JP 2002-87413 A

  By the way, in the discharged defective sheet, there is a case where confirmation work is performed on the content of the defect (for example, detailed points regarding the defect such as the position where the defect occurs, the cause of the defect, and the shape of the defective part). Specifically, this is a confirmation operation in which the worker specifies the defective content in the discharged defective sheet by visual observation or the like, and compares the specified defective content with the pass / fail judgment result by the inspection means. This confirmation work is performed in order to guide effective measures that lead to an increase in productivity by reducing defective sheets, and to check whether or not the inspection by the inspection means is performed normally.

  However, in general, in the hopper for defective products, a plurality of defective sheets with different inspection items determined to be defective are scattered. Therefore, before the above confirmation work, troublesome work for grasping the correspondence relationship between the defective sheet and the pass / fail judgment result (for example, checking the defective sheet one by one after taking into consideration the pass / fail judgment result by the inspection means) And it is necessary to grasp which defective sheet corresponds to which pass / fail judgment result), which may require a lot of time and effort. In addition, as a result, it takes time to complete the confirmation work, so it is not possible to execute effective measures leading to defect resolution at an early stage, or it takes time to confirm the reliability of the inspection by the inspection means. May be required.

  On the other hand, it is conceivable that one worker is attached to one inspection system (PTP packaging machine), and the above-described confirmation operation is performed each time one defective sheet is discharged. However, if the period during which the defective sheet is not discharged becomes longer, human resources may be wasted as a result.

  This invention is made | formed in view of the said situation, The objective is to provide the inspection system and PTP packaging machine which can perform the confirmation operation | work of a defective sheet quickly and easily.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. In the manufacturing process of the PTP sheet in which a predetermined article is stored in the pocket portion formed in the container film and the cover film is attached to the container film so as to close the pocket portion, the PTP sheet is finally obtained. By inspecting a plurality of inspection items with respect to an inspection object, an inspection system including an inspection unit that determines the quality of the PTP sheet in each inspection item,
Inspection information storage means for storing information related to the quality determination of the PTP sheet obtained by the inspection means;
Conveying means for conveying the PTP sheet;
Of the defective sheets that are the PTP sheets determined to be defective by the inspection means during the conveyance of the PTP sheet by the conveying means, only those that are determined to be defective in the selection items selected from the inspection items. Selective discharging means for selectively discharging;
Storage means for storing the defective sheets discharged by the selective discharge means in a state of being stacked in a line in the discharged order;
Take-out means capable of taking out the defective sheet from the storage means;
An inspection system comprising: display means for displaying the information stored in the inspection information storage means relating to the defective sheet taken out by the take-out means.

  Note that “a plurality of inspection items” refers to a case where there are a plurality of inspection items by one inspection means or a case where a plurality of inspection means for inspecting at least one inspection item are provided. Further, the “selection item” may be one or plural. Further, when there are a plurality of “selection items”, the selective discharge means may discharge only the defective sheets determined as defective in all of the plurality of selection items, or any one of the plurality of selection items The defective sheet determined to be defective in the step may be discharged.

  According to the means 1, only the defective sheets determined as defective in the selected inspection item (selected item) are selectively discharged and stored in the storage means. Therefore, regarding the defective sheet stored in the storage unit, it is possible to grasp the inspection items determined to be defective (that is, the rough contents of defects in the defective sheet) without checking the defective sheet itself. Further, when the defective sheet is taken out by the take-out means, the display means displays information relating to the quality determination of the taken-out defective sheet. Therefore, it is possible to easily collate the content of the defect in the actual defective sheet with the information related to the quality determination regarding the defective sheet.

  As described above, according to the above-described means 1, after grasping in advance the rough content of the defect in the defective sheet, based on the information related to the pass / fail judgment displayed on the display means, It is possible to easily collate with the information related to the quality determination regarding the defective sheet. Therefore, it is possible to quickly and easily confirm the defect content. As a result, it is possible to execute appropriate measures for eliminating defects earlier. In addition, since the confirmation work can be performed quickly, confirmation as to whether or not the pass / fail judgment relating to the selected item is normally performed by the inspection means, that is, the reliability confirmation of the inspection by the inspection means is earlier. It can be carried out.

  By the way, in order to display the information of the taken out defective sheets by the display means, the correspondence between each defective sheet stored in the storage means and the information related to the pass / fail judgment stored in the inspection information storage means is managed. It is necessary to keep it. Here, if it is configured such that defective sheets discharged in the storage means are stacked in a plurality of rows, etc., a sensor for grasping where the defective sheets are in order to manage the correspondence relationship, etc. A complicated device is required, and there is a risk that the device becomes complicated and the manufacturing cost increases.

  In this respect, according to the means 1, the defective sheets are stacked in a line in the discharged order, and therefore, in the storing means, the defective sheets are stacked in the order according to the discharging order. Therefore, the correspondence between each defective sheet stored in the storage means and the information related to the pass / fail judgment stored in the inspection information storage means without requiring a complicated device for grasping the position of the stored defective sheet Can be managed easily. Thereby, simplification of an apparatus and increase suppression of manufacturing cost can be aimed at more reliably.

  If the defective sheets are stacked and stored in a row, the number of stored defective sheets in the storage means may be limited to some extent. However, the storage means may not select all the defective sheets but select the defective ones. Since only the sheet is stored, a problem in the number of stored sheets is relatively difficult to occur.

Mean 2. The number of operations of discharging the defective sheet by the selective discharging unit and the number of operations of extracting the defective sheet by the extracting unit are grasped and stored in the storage unit based on the grasped both times. Estimated number information acquisition means for acquiring information relating to the number of defective sheets that should have been,
Real number information acquisition means for acquiring information relating to the number of defective sheets actually stored in the storage means;
The storage unit check unit for determining whether or not the information acquired by the estimated number information acquisition unit and the information acquired by the real number information acquisition unit are consistent with each other. Inspection system.

  According to the above means 2, the storage number check means provides information relating to the estimated number of stored defective sheets based on the number of operations of the selective discharge means and take-out means, and the actual number of defective sheets obtained by the real number information acquisition means. It is determined whether or not the information relating to the number of stored images is consistent. That is, the stored number check means determines whether or not the estimated number of stored defective sheets grasped by the operation of the selective discharging means and the actual number of stored defective sheets are equal. As a result, it is possible to detect that a defective sheet that should be stored due to an ejection error is not actually stored, or that a defective sheet that should not be taken out has been accidentally taken out. It can be ensured that the correct number of defective sheets are stored.

  If the estimated number of stored sheets is not equal to the actual number of stored sheets, and it cannot be ensured that the correct number of defective sheets are stored, PTP is used to prevent adverse effects caused by continued abnormal conditions. It is good also as performing the temporary stop process of the PTP packaging machine which manufactures a sheet | seat.

  Means 3. 3. The inspection system according to claim 2, wherein the real number information acquisition unit includes a height detection unit that detects a stacked height of the defective sheets in the storage unit.

  In the above means 1 and the like, since the defective sheets are stored in a state of being stacked in a line, the stacked height of the defective sheets is substantially proportional to the number of stored defective sheets.

  By utilizing this point, according to the means 3, the real number information obtaining means includes the height detecting means for detecting the stacked height of the defective sheets. Therefore, the number of defective sheets actually stored in the storage means can be easily grasped based on the stacked height of the defective sheets detected by the height detecting means.

Means 4. A plurality of the selective discharging means are provided,
Each of the selective discharge means discharges the defective sheets according to the different selection items,
The inspection system according to any one of means 1 to 3, wherein the storage means is provided corresponding to each of the selective discharge means.

  Hereinafter, an embodiment will be described with reference to the drawings.

  First, the PTP sheet 1 will be described. As shown in FIGS. 1 and 2, the PTP sheet 1 includes a container film 3 having a plurality of pocket portions 2 and a cover film 4 attached to the container film 3 so as to close the pocket portions 2. doing.

  The container film 3 is made of, for example, a transparent or translucent thermoplastic resin material that is relatively hard and has a predetermined rigidity, such as PP (polypropylene) or PVC (polyvinyl chloride).

  The cover film 4 is made of an opaque material (for example, an aluminum foil or the like) having a sealant made of, for example, a polyester resin applied on the surface.

  The PTP sheet 1 is formed in a substantially rectangular shape in a plan view, and two pocket rows composed of five pocket portions 2 arranged along the longitudinal direction of the sheet are formed in the lateral direction of the sheet. That is, a total of 10 pocket portions 2 are formed. Each pocket 2 stores one tablet 5 as an article (see FIG. 2).

  The PTP sheet 1 is manufactured into a sheet shape by punching a strip-shaped PTP film 6 (see FIG. 3) formed from the strip-shaped container film 3 and the cover film 4. The PTP film 6 in the present embodiment has a configuration in which the number of pocket portions 2 corresponding to one sheet is arranged along the width direction.

  Next, the PTP packaging machine 10 for manufacturing the PTP sheet 1 will be described. As shown in FIG. 4, on the most upstream side of the PTP packaging machine 10, the raw material of the strip-shaped container film 3 is wound in a roll shape. The drawer end side of the container film 3 wound in a roll shape is guided by the guide roll 14. The container film 3 is hooked on the intermittent feed roll 15 on the downstream side of the guide roll 14. The intermittent feed roll 15 is connected to a motor that rotates intermittently and transports the container film 3 intermittently.

  Between the guide roll 14 and the intermittent feed roll 15, a heating device 16 and a pocket portion forming device 17 are sequentially arranged along the conveyance path of the container film 3. Then, in a state where the container film 3 is heated by the heating device 16 and the container film 3 becomes relatively flexible, the pocket portion forming device 17 forms the plurality of pocket portions 2 at predetermined positions of the container film 3. In the present embodiment, the heating device 16 and the pocket portion forming device 17 correspond to pocket portion forming means. The pocket portion 2 is formed at an interval between the transport operations of the container film 3 by the intermittent feed roll 15.

  The container film 3 fed from the intermittent feed roll 15 is hung in the order of the tension roll 18, the guide roll 19 and the film receiving roll 20. Since the film receiving roll 20 is connected to a motor that rotates at a constant speed, the container film 3 is transported continuously and at a constant speed. The tension roll 18 is in a state where the container film 3 is pulled to the side where the container film 3 is tensioned by an elastic force, and prevents the container film 3 from slackening due to the difference in the transport operation between the intermittent feed roll 15 and the film receiving roll 20. The container film 3 is always kept in a tension state.

  A tablet filling device 21 is disposed between the guide roll 19 and the film receiving roll 20 along the conveyance path of the container film 3. The tablet filling device 21 has a function as a filling means for automatically filling the tablet 5 in the pocket portion 2. The tablet filling device 21 is configured to drop the tablets 5 by opening the shutter at predetermined intervals in synchronization with the transport operation of the container film 3 by the film receiving roll 20, and each pocket portion is accompanied by the shutter opening operation. 2 is filled with tablets 5.

  On the other hand, the original film of the cover film 4 formed in a band shape is wound in a roll shape on the most upstream side.

  The drawing end of the cover film 4 wound in a roll shape is guided toward the heating roll 25 by the guide roll 24. The heating roll 25 can be pressed against the film receiving roll 20, and the container film 3 and the cover film 4 are fed between the rolls 20 and 25. And the container film 3 and the cover film 4 pass between both the rolls 20 and 25 in a heating-pressing state, the cover film 4 is stuck to the container film 3, and the pocket part 2 is block | closed with the cover film 4. . Thereby, the PTP film 6 with which the tablet 5 was filled in each pocket part 2 is manufactured. In the present embodiment, the film receiving roll 20 and the heating roll 25 constitute a sealing means.

  The PTP film 6 sent out from the film receiving roll 20 is hung in the order of the tension roll 27 and the intermittent feed roll 28. Since the intermittent feed roll 28 is connected to a motor that rotates intermittently, the PTP film 6 is intermittently conveyed. The tension roll 27 is in a state in which the PTP film 6 is pulled toward the side to be tensioned by an elastic force, and prevents the PTP film 6 from slacking due to the difference in transport operation between the film receiving roll 20 and the intermittent feed roll 28. The PTP film 6 is always kept in tension.

  The PTP film 6 sent out from the intermittent feed roll 28 is hooked in the order of the tension roll 31 and the intermittent feed roll 32. Since the intermittent feed roll 32 is connected to an intermittently rotating motor, the PTP film 6 is intermittently conveyed. The tension roll 31 is in a state in which the PTP film 6 is pulled to the side where the PTP film 6 is tensioned by an elastic force, and prevents the PTP film 6 from loosening between the intermittent feed rolls 28 and 32.

  Between the intermittent feed roll 28 and the tension roll 31, a slit forming device 33 and a marking device 34 are sequentially arranged along the transport path of the PTP film 6. The slit forming device 33 has a function of forming a slit for separation at a predetermined position of the PTP film 6. The marking device 34 has a function of marking a predetermined position (for example, a tag portion) of the PTP film 6.

  The PTP film 6 sent out from the intermittent feed roll 32 is wound on the downstream side in the order of the tension roll 35 and the continuous feed roll 36. A sheet punching device 37 is disposed between the intermittent feed roll 32 and the tension roll 35 along the transport path of the PTP film 6. The sheet punching device 37 has a function as a sheet punching unit that punches the outer edge of the PTP film 6 in units of one PTP sheet. In the present embodiment, one PTP sheet 1 is obtained by one operation of the sheet punching device 37.

  The PTP sheet 1 punched by the sheet punching device 37 is transported by a take-out conveyor 38 to a transport / discharge device 53 described later.

  Further, a cutting device 41 is disposed on the downstream side of the continuous feed roll 36. Then, the unnecessary film portion 42 constituting the remaining material portion (scrap portion) remaining in a strip shape after being punched by the sheet punching device 37 is guided to the tension roll 35 and the continuous feed roll 36 and then guided to the cutting device 41. It is burned. The continuous feed roll 36 is in pressure contact with a driven roll, and performs a conveying operation while sandwiching the unnecessary film portion 42. The cutting device 41 has a function of cutting the unnecessary film portion 42 into a predetermined size and scrapping. The scrap is stored in the scrap hopper 43 and then disposed of separately.

  The rolls 15, 19, 20, 28, 31, 32 and the like have a positional relationship in which the roll surface and the pocket portion 2 face each other. Since the recessed part which accommodates is formed, the pocket part 2 is not crushed fundamentally. Further, the feeding operation is performed while the pocket portion 2 is accommodated in the recesses of the rolls 15 and the like, so that the intermittent feeding operation and the continuous feeding operation are reliably performed.

  Furthermore, the PTP packaging machine 10 selectively inspects the inspection target to be the PTP sheet 1 to selectively determine the quality of the PTP sheet 1 and the defective sheet 1A which is the PTP sheet 1 determined to be defective. The inspection system 50 is provided with a function of discharging.

  The inspection system 50 includes a pre-seal inspection unit 51, a post-seal inspection unit 52, a transport discharge device 53, a storage device 54 as a storage unit, a height detection sensor 55 as a height detection unit, a take-out device 56 as a take-out unit, A take-out operation device 57, a display device 58 as display means, a computer system 59, and a correspondence storage device 60 comprising a hard disk and the like are provided.

  The pre-seal inspection unit 51 is provided between the tablet filling device 21 and the film receiving roll 20. The pre-seal inspection section 51 is provided with a first inspection device T1, a second inspection device D, and a third inspection device A as inspection means in order from the upstream side. By these inspection devices T1, D, A, abnormalities relating to the tablet 5 and the container film 3 (sheet portion) are inspected. A more detailed configuration of each inspection apparatus T1, D, A will be described later.

  The post-seal inspection unit 52 is provided between the film receiving roll 20 and the tension roll 27. The post-seal inspection section 52 is provided with a fourth inspection apparatus E and a fifth inspection apparatus S as inspection means in order from the upstream side. By these inspection devices E and S, abnormality relating to the tablet 5 and the PTP film 6 (sheet portion) is inspected.

  Next, a more specific configuration of each inspection apparatus T1, D, A, E, S will be described with reference to FIG.

  Each of the inspection devices T1, D, A, E, and S includes an illumination device 110, a camera 111, a processing execution device 112, and the like.

  The illuminating device 110 transmits predetermined light (for example, an inspection target) from the opening side or the protruding portion side of the pocket portion 2 to the scheduled portion of the container film 3 or the PTP film 6 (that is, the inspection target). (Near-infrared light and visible light) can be irradiated.

  The camera 111 images the planned sheet portion from the opening side or the protruding side of the pocket portion 2. In the present embodiment, a CCD camera having sensitivity in the wavelength region of light emitted from the illumination device 110 is employed as the camera 111. Not limited to this, a CMOS camera may be employed. Note that a color CCD camera is employed for the camera 111 of some inspection apparatuses such as the third inspection apparatus A so that the colors can be identified.

  Image data (luminance image data or color image data) captured by the camera 111 is converted into a digital signal inside the camera 111 and then input to the processing execution device 112 in the form of a digital signal.

  The processing execution device 112 includes an image memory 113, an inspection result storage device 114, a determination memory 115, a data memory 116, a camera timing control device 117, and a CPU and an input / output interface 118. Various image processing such as processing, defect determination processing (inspection processing), and the like can be performed.

  The image memory 113 stores two-dimensional image data (image data) of a captured image output from the camera 111. An inspection is executed based on the image data stored in the image memory 113. Of course, when the inspection is executed, the image data may be processed. For example, it is conceivable to perform processing such as masking processing or shading correction. The shading correction is for correcting the lightness variation caused by the difference in position because there is a technical limit to uniformly illuminating the entire imaging range such as the container film 3 with the light of the illumination device 110. is there. Note that binarized image data obtained by performing binarization processing on image data at the time of inspection, masking image data subjected to masking processing, and the like are also stored in the image memory 113.

  The inspection result storage device 114 stores information such as coordinates related to image data, information related to pass / fail determination for a planned sheet part (inspection target), statistical data obtained by probabilistically processing the information, and the like. In the present embodiment, each of the inspection devices T1, D, A, E, and S inspects one or a plurality of predetermined inspection items X1 to X9 and Y1 to Y4, and own inspection result storage device 114. On the other hand, the information regarding the quality determination regarding the item which inspected is memorize | stored (refer FIGS. 6-10). The information relating to the pass / fail judgment includes more detailed information such as information indicating the position where the defect has occurred (for example, information specifying the tablet 5 in which an abnormality has occurred), but in FIGS. Information related to the determination is simplified. The inspection items X1 to X9 are items related to the quality of the tablet 5, and the inspection items Y1 to Y4 are items related to the quality of the sheet portion (the container film 3 and the cover film 4). Detailed contents of these inspection items X1 to X9 and Y1 to Y4 will be described later.

  Further, the information related to the pass / fail judgment is stored together with serial numbers LA1, LA2, LA3... (See FIG. 11) for specifying the scheduled seat portion (see FIGS. 6 to 10). 6 illustrates information related to the pass / fail determination stored in the first inspection apparatus T1, FIG. 7 illustrates information related to the pass / fail determination stored in the second inspection apparatus D, and FIG. FIG. 9 illustrates information related to pass / fail judgment stored in the fourth inspection apparatus E, and FIG. 10 illustrates information related to pass / fail determination stored in the third inspection apparatus A. The information regarding the quality determination memorize | stored is illustrated. In the present embodiment, the image memory 113 and the inspection result storage device 114 constitute inspection information storage means.

  The determination memory 115 stores determination values (threshold values, etc.) used for inspection. The determination value is set for each inspection item. The determination values used for the inspection include, for example, the dimensions of the PTP sheet 1, the pocket portion 2, the tablet 5, the shape and dimensions of the window frame for defining the inspection area, the threshold value for binarization processing, and the area determination The determination value, the color reference value related to the color identification inspection, and the like are included. In addition, among the determination values, there are determination values that are determined by statistically measuring inspection measurement results for items determined to be non-defective items in past inspections, such as determination values for inspecting tablet area values.

  The data memory 116 is constituted by, for example, a hard disk device. The data memory 116 stores defect determination date and time, image data, inspection conditions used for inspection, and the like.

  Further, in the present embodiment, the data memory 116 stores data related to the two-dimensional position of the pocket portion 2 with respect to the two-dimensional position of the tablet 5 in advance. In addition, data relating to the two-dimensional position of the pocket portion 2 in the normal PTP sheet 1 is also stored in advance in the data memory 116. By using these data, based on the position of the tablet 5, the position of the pocket portion 2 in the container film 3, and thus the position of the planned sheet portion in the container film 3 or the PTP film 6 can be specified.

  The camera timing control device 117 controls the imaging timing of the camera 111. Such imaging timing is controlled based on a signal from an encoder (not shown) provided in the PTP packaging machine 10, and imaging by the camera 111 is performed every time a predetermined amount of the container film 3 or the PTP film 6 is sent.

  The CPU and input / output interface 118 controls various controls in the inspection apparatuses T1, D, A, E, and S. For example, it has a function of executing various processing programs and transmitting / receiving various signals to / from the computer system 59. In addition, the CPU and the input / output interface 118 specify a planned sheet portion (inspection target) in the container film 3 or the PTP film 6 based on the positions of the pocket portion 2 and the tablet 5 in the image data. And the said serial number according to a conveyance order is set with respect to the specified sheet | seat planned site | part. The serial number of the planned sheet portion is increased one by one toward the upstream side in the conveyance direction. Of course, the serial numbers set for one scheduled sheet portion are the same in each of the inspection apparatuses T1, D, A, E, and S.

  Next, the configuration of each inspection device T1, D, A, E, S will be described in more detail.

The two claws 562 are maintained in a state of being rotated downward.

  Returning to FIG. 4, the take-out operation device 57 is operated by an operator or the like when taking out the defective sheet 1 </ b> A from the storage device 54. For example, a take-out input means (not shown) such as a push button is used. It has. The take-out operation device 57 outputs a predetermined take-out request signal to the computer system 59 when the input to the take-out input means is confirmed.

  The display device 58 includes, for example, a liquid crystal, and is configured to be able to send and receive signals to and from the computer system 59. The display device 58 can display various information based on signals received from the computer system 59.

  The computer system 59 includes a CPU as a calculation means, a ROM that stores various programs, a RAM that temporarily stores various data such as calculation data and input / output data, and a hard disk that can store various data for a long period of time. Yes. The computer system 59 can communicate with various apparatuses such as the inspection apparatuses T1, D, A, E, and S and the selective discharge apparatus 534, and controls the selective discharge apparatus 534 and the display apparatus 58. . For example, the computer system 59 can receive various types of information (image data, inspection conditions, information related to pass / fail determination, etc.) stored in each of the inspection apparatuses T1, D, A, E, and S. Based on the received information Control of the selective discharge device 534 and the like is performed.

  The computer system 59 is connected to input means (not shown) such as a keyboard and a touch panel, and one or a plurality of selections selected from the inspection items X1 to X9 and Y1 to Y4 by the input means. Items can be entered. The selection item is information for specifying a defective sheet 1A to be selectively discharged to the storage device 54 by the selective discharge device 534. The defective sheet 1A determined as defective in this selection item is selected by the selective discharge device 534. It will be discharged selectively. The input selection items are stored (updated) in the hard disk of the computer system 59, and the stored selection items can be displayed on the display device 58.

  However, in the present embodiment, when a selection item is input in a state where the defective sheet 1A is already stored in the storage device 54, a predetermined storage process is executed, and it cannot be changed to a new selection item. ing. That is, only when the defective sheet 1A is not stored in the storage device 54, it can be changed to a new selection item. Thereby, it is possible to prevent the defective sheets 1 </ b> A relating to different selection items from being simultaneously present in the storage device 54. Examples of the storage process include a process of displaying on the display device 58 that the defective sheet 1A is stored in the storage device 54 and that the selection item cannot be input (changed).

  Further, as shown in FIG. 13, the computer system 59 includes an inspection result processing unit 591, a discharge processing unit 592, an extraction processing unit 593, an estimated number information acquisition unit 594 as an estimated number information acquisition unit, and real number information. An acquisition processing unit 595 and a storage number check unit 596 as a storage number check unit are provided.

  The inspection result processing unit 591 associates a predetermined discharge order number with the serial number of the planned sheet portion related to the defective sheet 1A that has been determined to be defective in the stored selection item, and then identifies both of them as defects in the correspondence storage device 60. It has a function of sequentially storing data in a sheet table (see FIG. 14). Specifically, at the timing when the inspection by each of the inspection devices T1, D, A, E, and S with respect to one planned sheet portion is completed, based on the information related to the pass / fail judgment in the inspection devices T1, D, A, E, and S. Then, it is determined whether or not the PTP sheet 1 obtained from the one planned sheet portion is determined to be defective in the selection item. And when it is determined that the selection item is defective, the serial number of the scheduled part of the sheet relating to the PTP sheet 1 (defective sheet 1A) is associated with the discharge order number, and both are stored in the correspondence storage device. It is stored in 60 defective sheet tables.

  As the discharge order number, the initial value is set to 1, for example, and a value of a discharge order counter that is incremented by 1 each time information is stored in the defective sheet table is set (note that the discharge order number is set). The forward counter may be a loop counter that returns to an initial value when a predetermined maximum value is reached). For example, “1” is associated with the serial number of the defective sheet 1 </ b> A that is first discharged to the storage device 54 as the discharge order number. That is, it can be said that the discharge order number indicates the discharge order of the defective sheets 1A determined as defective by the selection item.

  In this embodiment, some of the inspection items executed by the inspection apparatuses T1, D, A, E, and S are duplicated. However, the inspection result processing unit 591 relates to the duplicate inspection items. Determines that the inspection item is defective if it is determined as defective by at least one of the inspection devices T1, D, A, E, and S. For example, regarding the inspection item X1, when the inspection devices T1 and D are determined to be good and the inspection devices A and E are determined to be defective, the inspection result processing unit 591 determines that the inspection item X1 is defective. In this embodiment, when there are a plurality of selection items, the inspection result processing unit 591 determines that the selection items are defective only when all the selection items are defective.

  The discharge processing unit 592 has a function of controlling the operation of the selective discharge device 534 and discharging only the defective sheet 1 determined to be defective by the selection item to the storage device 54. Specifically, the discharge processing unit 592 reaches the selective discharge device 534 when the defective sheet 1 </ b> A is determined to be defective in the selected item based on a signal from an encoder provided in the transport discharge device 53 (conveyor 532). When it is determined that it is immediately before, a discharge operation signal is sent to the selective discharge device 534.

  Further, the discharge processing unit 592 confirms the actual stored number of defective sheets 1A stored in the RAM or the like in the storage device 54. If the actual stored number is 0, the discharge processing signal is followed by the discharge operation signal. The second opening signal is output to the extracting device 56. The actual number of stored sheets is acquired by the real number information acquisition processing unit 595 (details will be described later). When the second opening signal is output, the second claw portion 562 is rotated downward. Therefore, the defective sheet 1 </ b> A discharged to the empty storage device 54 is supported by the first claw portion 561 instead of the second claw portion 562.

  On the other hand, when the actual number of stored sheets is one or more, the discharge processing unit 592 outputs only the discharge operation signal. Accordingly, the defective sheet 1A thrown into the storage device 54 is supported by the second claw portion 562 directly or through another defective sheet 1A.

  The take-out processing unit 593 controls the operation of the take-out device 56, takes out the defective sheet 1A from the storage device 54, and displays the information related to the quality determination of the taken-out defective sheet 1A on the display device 58. Have

  More specifically, when a take-out request signal is input from the take-out operation device 57, the take-out processing unit 593 confirms the actual number of stored defective sheets 1A in the storage device 54. When the actual number of stored sheets is one, the take-out processing unit 593 outputs the first opening signal to the take-out device 56 and rotates the first claw portion 561 downward. Thereby, one defective sheet 1A stored in the storage device 54 is taken out.

  On the other hand, when the actual number of stored sheets is two or more, the extraction processing unit 593 outputs a first release signal to the extraction device 56. As a result, only one of the plurality of defective sheets 1 </ b> A stored in the storage device 54 that is positioned at the lowest position (that is supported by the first claw portion 561) is taken out from the storage device 54. Next, the extraction processing unit 593 stops outputting the first opening signal and then outputs the second opening signal for a certain time. Thereby, the defective sheet 1A supported by the second claw part 562 is lowered, and the defective sheet 1A located at the bottom is supported by the first claw part 561. As described above, in the present embodiment, the plurality of defective sheets 1 </ b> A are not taken out at a time by shifting the rotation timings of both the claw portions 561 and 562.

  Further, the take-out processing unit 593 performs a process for causing the display device 58 to display information related to the pass / fail determination of the taken out defective sheet 1A immediately after sending the first opening signal. Specifically, the take-out processing unit 593 specifies a serial number associated with the same discharge order number as the value of a predetermined result display counter based on the defective sheet table. Then, information related to the pass / fail judgment relating to the serial number is extracted from the image memory 113 and the inspection result storage device 114 of each inspection device T1, D, A, E, S, and a signal for displaying the extracted information is displayed. The data is output to the display device 58. In the present embodiment, the take-out processing unit 593 outputs a signal for displaying a pass / fail judgment result by each of the inspection apparatuses T1, D, A, E, and S, information indicating the occurrence position of a defect, an image of the defective sheet 1A, and the like. Output. The initial value of the result display counter is the same as the value obtained by subtracting 1 from the initial value of the discharge order number (for example, 0), and immediately after the first release signal is sent, Increased by 1 before extracting information.

  Here, the above will be described in more detail with specific examples. For example, three defective sheets 1A are stored in the storage device 54, and the discharge order number relating to these defective sheets 1A is “1 (initial value)”. It is assumed that they are “2” and “3”. At this time, the defective sheet 1A having the discharge order number “1” has not been taken out yet, that is, the first release signal has not been sent yet, so the value of the result display counter becomes “0 (initial value)”. ing. In this state, when the take-out operation device 57 is operated and a take-out request signal is output from the take-out operation device 57 to the computer system 59, that is, removal of the defective sheet 1A from the storage device 54 is requested. Then, the first release signal is output from the take-out processing unit 593 for a certain period of time, and the defective sheet 1A having the discharge order number “1” is taken out from the storage device 54. In addition, the extraction processing unit 593 increments the value of the result display counter by 1 immediately after the output of the first release signal. As a result, the value of the result display counter becomes “1”. Subsequently, the take-out processing unit 593 specifies a serial number associated with the same discharge order number as the value of the result display counter (“1”), and information on pass / fail judgment relating to this serial number is provided for each inspection device T1, D, Extract from A, E, S. Then, by outputting a signal for displaying the extracted information to the display device 58, information related to the pass / fail judgment on the extracted defective sheet 1 </ b> A having the discharge order number “1” is displayed on the display device 58. The Rukoto. Further, after the output of the first opening signal is stopped, the second opening signal is output for a certain time. As a result, the defective sheet 1 </ b> A with the discharge order number “2” is supported by the first claw portion 561. If the take-out operation device 57 is operated again, the defective sheet 1A with the discharge order number “2” is taken out, and the value of the result display counter is updated to “2”. On the basis of the information, the display device 58 displays information relating to the pass / fail determination for the defective sheet 1 </ b> A with the ejected discharge order number “2”. Further, the defective sheet 1 </ b> A having the discharge order number “3” is supported by the first claw portion 561.

  Thus, when the defective sheet 1A is stored in the storage device 54, the take-out processing unit 593 operates as described above, but when the defective sheet 1A is not stored in the storage device 54, the first release signal The predetermined space-time processing is executed without performing output such as the above and updating the result display counter. Examples of the space-time process include a process of displaying on the display device 58 that the defective sheet 1A is not stored in the storage device 54.

  The estimated number information acquisition unit 594 should be stored in the storage device 54 based on the number of ejection operations of the defective sheet 1A by the selective ejection device 534 and the number of ejection operations of the defective sheet 1A by the extraction device 56. Information on the number of defective sheets 1A is acquired. In the present embodiment, the estimated number information acquisition unit 594 uses the storage device 54 based on the total number of discharge operation signals output from the discharge processing unit 592 and the number of first release signals output from the extraction processing unit 593. The number of defective sheets 1A that should have been stored in (the estimated number of stored sheets) is acquired. For example, when the total number of discharge operation signals output from the discharge processing unit 592 is three and the total number of first release signals output from the extraction processing unit 593 is one, the estimated number information acquisition unit 594 Obtains “2” as the estimated number of stored sheets.

  In the present embodiment, the estimated number information acquisition unit 594 temporarily stores the acquired estimated number of stored images in a RAM or the like. The stored estimated stored number is updated each time a new estimated stored number is acquired.

  When the selective discharge device 534 is discharged, a discharge execution signal is output from the selective discharge device 534 to the computer system 59 (estimated number information acquisition unit 594), and at the time of the extraction operation by the extraction device 56, the extraction device 56 The extraction execution signal may be output to the computer system 59 (estimated number information acquisition unit 594). Then, the estimated number information acquisition unit 594 acquires the number of sheets of defective sheets 1A (estimated number of stored sheets) that should be stored in the storage device 54, based on the number of the discharge execution signal and the extraction execution signal that are input. It is good. That is, in this embodiment, the estimated number of stored sheets is acquired based on the number of operation requests from the computer system 59 to the selective discharge device 534 and the extraction device 56, but the selective discharge device 534 and the extraction device 56 are obtained. The estimated number of stored sheets may be acquired based on the actual number of operations in step. Of course, the estimated number of stored sheets may be obtained more accurately by using both.

  The real number information acquisition processing unit 595 acquires information related to the number of defective sheets 1A actually stored in the storage device 54 based on the height information input from the height detection sensor 55. In the present embodiment, the hard disk of the computer system 59 stores in advance a number deriving table in which the type of height information and the number of defective sheets 1A are associated with each other. By referring to the table, the number of defective sheets 1A actually stored in the storage device 54 (actual stored number) is acquired based on the input height information. In the present embodiment, the real number information acquisition unit is configured by the height detection sensor 55 and the real number information acquisition processing unit 595.

  Further, the real number information acquisition processing unit 595 temporarily stores the acquired actual number of stored sheets in a RAM or the like. The stored actual stored number is updated each time a new actual stored number is acquired.

  The storage number check unit 596 determines whether the information acquired by the estimated number information acquisition unit 594 matches the information acquired by the real number information acquisition processing unit 595. In the present embodiment, the storage number check unit 596 determines whether or not the estimated stored number acquired by the estimated number information acquisition unit 594 is equal to the actual stored number acquired by the real number information acquisition processing unit 595. To do.

  The storage number check unit 596 also checks whether or not the actual stored number is equal to or less than the maximum stored number in the storage device 54 set in advance.

  When the estimated stored number is not equal to the actual stored number, or when the actual stored number exceeds the maximum stored number, the stored number check unit 596 executes the process when the number is abnormal. Examples of the process when the number of sheets is abnormal include a process of temporarily stopping the operation of the PTP packaging machine 10 and a process of notifying that there is an abnormality in the stored number of sheets. In the present embodiment, a process for temporarily stopping the operation of the PTP packaging machine 10 is executed as the process when the number of sheets is abnormal.

  Next, various processes performed by the computer system 59 will be described.

  As shown in FIG. 15, in the main process in the computer system 59, the selection item storage process in step S1, the correspondence specifying process in step S2, the discharge process in step S3, the removal process in step S4, and the process in step S5 The storage number check process is repeatedly executed every predetermined time (for example, several ms).

  First, the selection item storage process will be described. The selection item storage process is a process for storing the selection item input via the input unit in a hard disk or the like of the computer system 59. In the selection item storage process, as shown in FIG. 16, first, in step S11, it is determined whether or not a selection item has been input. If the selection item is input (step S11: YES), the process proceeds to step S12. On the other hand, when the selection item is not input (step S11: NO), the selection item storage process is terminated.

  In step S12, the actual number of stored defective sheets 1A obtained by the real number information acquisition processing unit 595 and stored in the RAM or the like is checked to determine whether or not the number of stored defective sheets 1A is zero. . The actual number of stored sheets is acquired by the stored number check process in step S5, and its initial value is set to zero. The process of step S12 prevents a change in the inspection items determined to be defective in the stored defective sheet 1A by prohibiting the change of the selection item in the state where the defective sheet 1A is already stored. To be done.

  If the actual number of stored sheets is not 0 (step S12: NO), in step S13, a process at the time of storage (for example, a process of outputting a signal for displaying that the selection item cannot be input to the display device 58). To finish the selection item storing process.

  On the other hand, when the actual number of stored sheets is 0 (step S12: YES), in step S14, the input selection item is stored in the hard disk of the computer system 59, and the selection item storage process is terminated. If a selection item has already been stored, it is updated to a newly input selection item.

  Next, the correspondence specifying process will be described. The correspondence specifying process is a process of associating the serial number of the defective sheet 1 </ b> A determined as defective in the selection item with the discharge order number and storing them in the defective sheet table of the correspondence storage device 60. In the correspondence specifying process, as shown in FIG. 17, first, in step S21, whether or not the inspection by one of the inspection devices T1, D, A, E, and S for one inspection object (planned sheet portion) is completed. Confirm. This is confirmed based on, for example, a signal from the fifth inspection apparatus S arranged on the most downstream side. If a negative determination is made in step S21, that is, if it is a stage before the inspection results by the respective inspection devices T1, D, A, E, and S are obtained, the correspondence specifying process is terminated.

  On the other hand, if an affirmative determination is made in step S21, the inspection target (scheduled sheet) that has been inspected is determined in step S22 based on the information relating to the pass / fail determination stored in each inspection device T1, D, A, E, S. It is confirmed whether or not (part) is determined to be defective in the selection item. If a negative determination is made in step S22, that is, if the inspection target that has been inspected is a non-defective product, or if it is a defective product but has been determined to be good in the selection item, the correspondence is specified. The process ends.

  On the other hand, if an affirmative determination is made in step S22, that is, if the inspection target that has been inspected is determined to be defective in the selected item, in step S23, the PTP sheet 1 related to the inspection target is determined. The serial number and the discharge order number are associated with each other, and the correspondence between the two is stored in the defective sheet table. As described above, the value of the discharge order counter is set as the discharge order number. For example, when the inspection item X1 is selected as the selection item and the inspection target of the serial number “LA4” is determined to be defective by the inspection item X1 (see FIGS. 6 to 9), the serial number “LA4” is used. The discharge order number (the value of the discharge order counter, whose initial value is 1 for example) is stored in the defective sheet table (see FIG. 14). Next, in step S24, the value of the discharge order counter is incremented by 1, and the correspondence specifying process is terminated.

  Next, the discharging process will be described. The process at the time of discharge is mainly a process for driving the selective discharge device 534 to store the defective sheet 1 </ b> A determined as defective by the selection item in the storage device 54. In the discharging process, as shown in FIG. 18, first, in step S31, based on the signal from the encoder provided in the transport / discharge device 53 (conveyor 532), the defect to be discharged whose failure is determined by the selection item. It is determined whether or not the sheet 1A is just before reaching the discharge rail 534A. If a negative determination is made in step S31, the discharging process is terminated.

  On the other hand, if an affirmative determination is made in step S32, a discharge operation signal is output to the selective discharge device 534. As a result, the discharge rail 534 </ b> A rotates downward, and the defective sheet 1 </ b> A determined to be defective as a selection item is discharged to the storage device 54.

  In step S33 following step S32, it is determined whether or not the actual number of stored sheets is zero. When the actual number of stored sheets is one or more (step S33: NO), the process proceeds to step S35 without outputting the second release signal. As a result, the discharged defective sheet 1A is supported by the second claw portion 562 directly or via another defective sheet 1A.

  On the other hand, when the actual number of stored sheets is 0 (step S33: YES), in step S34, the second opening signal is output to the take-out device 56 for a predetermined time, and the process proceeds to step S35. Due to the output of the second release signal, the defective sheet 1 </ b> A discharged to the storage device 54 in a state where the defective sheet 1 </ b> A is not stored is supported by the first claw portion 561.

  In the subsequent step S35, the value of the discharge operation number counter is increased by 1. The discharge operation number counter is used to count the total number of discharge operations, and its initial value is set to zero.

  In the subsequent step S36, the value of the waiting counter is set to a predetermined set value, and the discharging process is terminated. The waiting counter is used to skip the storage number check process in step S5 until the defective sheet 1A comes to rest in the storage device 54 after discharge (storage) or removal of the defective sheet 1A. The initial value is set to 0. The set value of the waiting counter is a real value larger than 0 based on the time required for the defective sheet 1A to come to rest in the storage device 54 after the defective sheet 1A is discharged (stored) or taken out. Yes, and stored in advance in the computer system 59.

  Next, the process at the time of taking out will be described. The processing at the time of taking out is mainly processing for executing the removal of the defective sheet 1A from the storage device 54 and the display of information relating to the quality determination of the taken out defective sheet 1A. In the extraction process, as shown in FIG. 19, first, in step S41, it is determined whether or not the extraction operation device 57 has been operated, that is, whether or not an extraction request signal has been input. If a negative determination is made in step S41, the removal process is terminated.

  On the other hand, if an affirmative determination is made in step S41, that is, if removal of the defective sheet 1A from the storage device 54 is requested, whether or not the actual number of stored defective sheets 1A is one or more in step S42. Determine whether or not. If a negative determination is made in step S42, that is, if the defective sheet 1A to be taken out does not exist in the storage device 54, a space time process (for example, to display that the storage device 54 is empty) is displayed in step S43. Is output to the display device 58), and the extraction process is terminated.

  On the other hand, when an affirmative determination is made in step S42, an extraction operation process is executed in step S44. In the take-out operation process, as shown in FIG. 20, first, in step S441, it is determined whether or not the actual number of stored sheets is one. If the actual number of stored sheets is one (step S441: YES), in step S442, the first release signal is output to the extraction device 56 for a certain period of time, and the extraction operation process is terminated. Thereby, the 1st nail | claw part 561 rotates below, and the 1 defective sheet 1A stored in the storage apparatus 54 is taken out.

  On the other hand, if the actual number of stored sheets is two or more (step S441: NO), first, in step S443, the first opening signal is output to the take-out device 56 for a certain period of time. As a result, among the plurality of defective sheets 1 </ b> A stored in the storage device 54, only the lowermost one supported by the first claw portion 561 is taken out from the storage device 54.

  Next, in step S444, after the output of the first opening signal is stopped, the second opening signal is output for a predetermined time. Due to the output of the second release signal, the defective sheet 1A supported directly or indirectly by the second claw portion 562 is lowered, and the defective sheet 1A positioned at the bottom is supported by the first claw portion 561; Become.

  In step S445 following step S444, the value of the waiting counter is set as the set value, and the take-out operation process is terminated.

  Returning to FIG. 19, in step S45 following the extraction operation process, the value of the extraction operation number counter is incremented by one. The take-out operation number counter is used to count the total number of take-out operations, and its initial value is set to zero.

  In subsequent step S46, the value of the result display counter is incremented by one. Thereby, the value of the result display counter becomes the same as the discharge order number relating to the taken out defective sheet 1A.

  In step S47, a result display process is executed, and the process at the time of extraction ends. In the result display process, a serial number associated with the same discharge order number as the value of the result display counter is specified based on the defective sheet table, and information regarding pass / fail judgment of the PTP sheet 1 related to this serial number is stored in each inspection device T1. , D, A, E, S. Then, a signal for displaying the extracted information related to pass / fail judgment is output to the display device 58. Thereby, the information regarding the pass / fail judgment result of the taken out defective sheet 1A such as the pass / fail judgment result by each of the inspection apparatuses T1, D, A, E, S, the information indicating the occurrence position of the fault, the image of the faulty sheet 1A, etc. It is displayed on the display device 58.

  Next, the storage number check process will be described. The stored number check process is a process for checking the number of defective sheets 1A stored in the storage device 54, such as whether or not the estimated stored number matches the actual stored number. In the storage number check process, as shown in FIG. 21, first, in step S51, it is determined whether or not the value of the wait counter is zero. That is, it is determined whether or not it is the timing immediately after the storage process of the defective sheet 1A in the storage device 54 and the extraction process of the defective sheet 1A in a state where a plurality of defective sheets 1A are stored. If the processing of step S51 is the timing immediately after the storage or removal of the defective sheet 1A, the defective sheet 1A is not stationary in the storage device 54, and the height acquired by the height detection sensor 55 is high. This is performed in order to obtain more accurate height information (actual number of stored sheets) in consideration of the possibility that the height information may not correspond to the actual number of stored sheets.

  If a negative determination is made in step S51, the process proceeds to step S52, the value of the waiting counter is decreased by 1, and the storage number check process is terminated.

  On the other hand, when an affirmative determination is made in step S51, that is, when it is considered that the height detection sensor 55 can obtain more accurate height information corresponding to the actual number of stored sheets, Control goes to step S53. In step S53, based on the height information input from the height detection sensor 55, the number of defective sheets 1A actually stored in the storage device 54 by the real number information acquisition processing unit 595 (actual storage number). ) Is acquired. The acquired actual stored number is stored in a RAM or the like.

  In step S54 following step S53, the number of defective sheets 1A that should be stored in the storage device 54 (estimated stored number) is acquired based on the value of the discharge operation number counter and the value of the extraction operation number counter. . In the present embodiment, the estimated number of stored sheets is acquired by subtracting the value of the take-out operation number counter from the value of the discharge operation number counter. The acquired estimated number of stored images is stored in a RAM or the like.

  Next, in step S55, it is determined whether or not the estimated stored number acquired by the estimated number information acquisition unit 594 is equal to the actual stored number acquired by the real number information acquisition processing unit 595. If a positive determination is made in step S55, the process proceeds to step S56.

  In a succeeding step S56, it is determined whether or not the actual stored number is equal to or less than the maximum stored number. If the determination in step S56 is affirmative, there is no problem with the number of stored sheets, and the stored number check process is terminated without performing any special process.

  On the other hand, if a negative determination is made in step S55 or step S56, the process for abnormal number of sheets is executed in step S57, and the storage number check process is terminated. In the present embodiment, when the number abnormality process is executed, the operation of the PTP packaging machine 10 is temporarily stopped and the main process is stopped.

  As described above in detail, according to the present embodiment, only the defective sheet 1 </ b> A determined to be defective in the selected inspection item (selected item) is selectively discharged and stored in the storage device 54. Therefore, regarding the defective sheet 1A stored in the storage device 54, it is possible to grasp the inspection items determined as defective (that is, the rough contents of defects in the defective sheet) without checking the defective sheet 1A itself. Further, when the defective sheet 1A is taken out by the take-out device 56, the display device 58 displays information related to the quality determination of the taken out defective sheet 1A. Therefore, it is possible to easily collate the content of the defect in the actual defective sheet 1A with the information related to the quality determination regarding the defective sheet 1A.

  As described above, according to the present embodiment, after the rough content of the defect in the defective sheet 1A is grasped in advance, the content of the defect in the actual defective sheet 1A is based on the information regarding the quality determination displayed on the display device 58. And information relating to the quality determination of the defective sheet 1A can be easily verified. Therefore, it is possible to quickly and easily confirm the defect content. As a result, it is possible to execute appropriate measures for eliminating defects earlier. Further, since the confirmation work can be performed quickly, confirmation as to whether or not the quality determination related to the selected item is normally performed in the inspection devices T1, D, A, E, and S, that is, the inspection device T1. , D, A, E, and S can confirm the reliability of the inspection earlier.

  Further, since the defective sheets 1A are stacked in a line in the discharged order, the defective sheets 1A are naturally stacked in the order in accordance with the discharge order in the storage device 54. Therefore, it is possible to easily manage the correspondence between each defective sheet 1A stored in the storage device 54 and the information related to the pass / fail determination stored in the inspection result storage device 114 and the like. Thereby, simplification of an apparatus and increase suppression of manufacturing cost can be aimed at more reliably.

  Further, if the defective sheets 1A are stacked and stored in a row, the number of stored defective sheets 1A in the storage device 54 may be limited to some extent, but not all the defective sheets 1A are stored in the storage device 54. Only the selected defective sheet 1A is stored. Therefore, it is possible to make the problem of the number of stored sheets less likely to occur.

  In addition, the storage number check unit 596 estimates the number of stored defective sheets 1A based on the number of operations of the selective discharge device 534 and the take-out device 56, and the actual number of defective sheets 1A obtained by the real number information acquisition processing unit 595 and the like. It is determined whether or not the number of stored images matches. As a result, the defective sheet 1A that should be stored due to an ejection error is not actually stored, the defective sheet 1A that should be taken out is not actually taken out, and the defective sheet 1A that should not be taken out originally. It can be detected that the sheet has been taken out by mistake, and as a result, it is possible to more reliably ensure that the correct number of defective sheets 1A are stored in the storage device 54.

  Furthermore, in this embodiment, the stored number check unit 596 checks whether the number of defective sheets 1A stored in the storage device 54 is equal to or less than the maximum stored number. Therefore, it is possible to prevent a situation where the storage device 54 is full and the defective sheet 1A cannot be stored, and the defective sheet 1A can be stored more reliably.

  In addition, since the defective sheets 1A are stored in a stacked state, the stacked height of the defective sheets 1A is substantially proportional to the number of stored defective sheets 1A. By utilizing this point, in the present embodiment, a height detection sensor 55 that detects the stacked height of the defective sheets 1A is provided. Therefore, the number of defective sheets 1A actually stored in the storage device 54 can be easily grasped based on the stacked height of the defective sheets 1A detected by the height detection sensor 55.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, one selective discharge device 534 is provided. However, as shown in FIG. 22, a plurality of selective discharge devices 534 are provided along the conveyance path of the PTP sheet 1, and each selective discharge device 534 is provided. In the discharge device 534, the defective sheets 1A relating to different selection items may be discharged to the storage devices 54 provided corresponding to the respective selective discharge devices 534. For example, in the first selective discharge device 534 along the conveyance path, the defective sheet 1A determined to be defective by a predetermined selection item (for example, the inspection item X1) is discharged, and the second along the conveyance path. The selective discharge device 534 may be configured to discharge the defective sheet 1A that has been determined to be defective by a selection item (for example, the inspection item X2) different from the predetermined selection item. With this configuration, it is possible to separately store the defective sheets 1 </ b> A having different selection items for the plurality of storage devices 54. Therefore, the confirmation work of the defective sheet 1A related to a certain selection item and the confirmation work of the defective sheet 1A related to other selection items can be performed in parallel. As a result, more appropriate measures based on multiple confirmation tasks (multiple examinations) can be implemented at an early stage.

  (B) In the above embodiment, the selective discharge device 534 is configured to store the defective sheet 1A in the storage device 54 as the discharge rail 534A rotates. On the other hand, as shown in FIGS. 23 and 24, the selective discharge device 535 includes a discharge rail 535A that constitutes a part of the transport table 531 and a drive unit 535B that can move the discharge rail 535A up and down. When the discharge rail 535A is moved upward, the defective sheet 1A is pushed into the storage device 61 from the lower opening of the storage device 61 disposed above the discharge rail 535A. May be.

  In this case, a drop restricting portion 62 that can be rotated by applying a force from below is provided in the lower opening of the storage device 61 so that the defective sheet 1 can be pushed into the storage device 61 from the lower opening. However, the defective sheet 1A stored in the storage device 61 may be configured not to fall. Further, in accordance with the storage device 61 being disposed above the transport table 531, the conveyor 536 is disposed below the transport table 531, and the PTP sheet 1 is sandwiched between the transport claws 537 protruding upward. It may be conveyed. Further, in order to store the defective sheet 1A in the storage device 61 more reliably, the PTP sheet 1 may be temporarily stopped when the defective sheet 1A is stored (the discharge rail 535A is moved up). When the PTP sheet 1 is transported with the transport claws 537 being sandwiched, the PTP sheet 1 can be temporarily stopped by temporarily halting the transport claws 537.

  In addition, as the take-out device 63 as the take-out means, as shown in FIG. 25, one having a suction means capable of sucking and holding the defective sheet 1A stored in the uppermost part of the storage device 61 may be used. In this case, a height detection sensor 64 is provided as a height detection means for the take-out device 63, and when the take-out device 63 is arranged in a stationary state vertically above the storage device 61 (for example, take-out The height of the defective sheets 1 </ b> A may be detected by the height detection sensor 64 at a time other than during operation.

  (C) In the above-described embodiment, the PTP film 6 has a configuration in which the number of pocket portions 2 corresponding to one sheet is arranged along the width direction. The number of pocket portions 2 corresponding to the number may be arranged.

  In this case, a plurality of transport / discharge devices 53, storage devices 54, and the like are provided, and the PTP sheet 1 obtained by punching depends on the arrangement position along the width direction of the PTP film 6 before punching. Alternatively, it may be configured to be distributed to different transport discharge devices 53 and the like. For example, when the PTP film 6 has a configuration in which the number of pocket portions 2 corresponding to three sheets are arranged along the width direction, three transport discharge devices 53 and three storage devices 54 are prepared. The PTP sheet 1 arranged on one edge side in the width direction of the PTP film 6 before the punching was guided to the first transport / discharge device 53 and the like, and arranged at the center in the width direction of the PTP film 6 before the punching. The PTP sheet 1 is guided to the second transport / discharge device 53 and the PTP sheet disposed on the other end in the width direction of the PTP film 6 before punching is guided to the third transport / discharge device 53 and the like. Also good. With this configuration, the cause of the failure can be identified earlier and easily. For example, when there are a relatively large number of defective sheets 1A stored in the first transport / discharge device 53 or the like, some defect is present in the portion corresponding to the portion of the container film 3 or the PTP film 6 on one side edge in the width direction. This makes it easier to predict whether this is occurring. Therefore, it is possible to execute more appropriate measures for eliminating the defects at an earlier stage.
