Description

  The present invention relates to a parts billing program, a recording medium, a parts billing system, and a parts billing method for automating replenishment billing work for parts prepared in a production line for supply to a production line.

Parts used in the production line must be prepared in the production line without excess or deficiency and appropriately replenished as necessary. The amount of parts used varies from production line to production line depending on the operating status of the production line. In the batch automatic ordering method, the stock increases unnecessarily. The number of parts that can be stocked varies from production line to production line. Thus, for example, a system has been developed in which an ordering instruction card is issued when a part is consumed, the information is transmitted to a parts supplier through the Internet, and an appropriate replenishment is requested for each production line ( Patent Document 1).

  Here, the conventional technique has the following problems to be solved. In the ordering instruction card system, a card for specifying a part and its necessary replenishment amount is issued at the same time as the part is consumed, so that a replenishment request can be made reliably. However, capital investment for issuing ordering instruction cards is required. In addition, it is necessary to have a patrol person who monitors the issue status of the ordering instruction card and collects it, and personnel costs cannot be ignored. The present invention has been made paying attention to the above points, and it is an object of the present invention to provide a system capable of automatically and automatically replenishing parts with simple equipment.

In each embodiment of the present invention, the above-described problems are solved by the following configurations.
<Configuration 1> An identification information acquisition unit that acquires identification information attached to a part to be supplied to a production line, and production plan data that uses the part specified by the identification information are read to determine the use schedule of the part. The use schedule calculation means for calculating, the existing number calculation means for calculating the existing number of the parts prepared to be supplied to the production line, the existing number of the parts and the use schedule of the parts are compared, A parts billing system comprising: a replenishment time calculating means for calculating a time when the parts need to be replenished; and an output control means for controlling an output of the calculated replenishment time of the parts.

  When identification information such as a barcode attached to a part is read, the time when the part needs to be replenished can be automatically calculated and the result can be output. Since the replenishment time is automatically calculated from the relationship between the existing number of parts prepared on the production line and the use schedule of the parts, the status of the production line can be accurately and promptly communicated to the manager. By displaying the information indicating the replenishment time, it is possible to inform the manager of the intention of the replenishment request as it is.

  <Structure 2> In the parts billing system according to Structure 1, the output control means outputs a calculation record of past replenishment times of parts having a predetermined relationship with the parts specified by the identification information.

  In the system of this embodiment, the terminal device 11 is arranged on the production line, and the terminal device 12 is arranged in the warehouse. Although there are usually a plurality of production lines, only one line is displayed here. The server 15 is arranged at an arbitrary location on the network 10. Further, in this embodiment, the server 15 acquires parts identification information, calculates the parts replenishment time, generates replenishment request information, and displays them on the production line or warehouse. However, all or part of these functions may be shared by the terminal device 11 or the terminal device 12. Both terminal devices 11 and 12 are used for outputting information. Therefore, it can be replaced with a display or the like that is directly controlled via the network 10. That is, the system of the present invention can be realized by the server 15 alone, or can be realized by only the terminal devices 11 and 12 connected via the network 10. Furthermore, it can be realized by a combination of the terminal device 11 or the terminal device 12, peripheral equipment, and the server 15.

FIG. 2 is a hardware block diagram of the system main part of the present embodiment.
The system shown in FIG. 1 is realized by hardware as shown in FIG. A terminal device 11 disposed on the production line side and a terminal device 12 disposed on the warehouse side are connected to the network 10. The terminal device 11 controls the display 51, the printer 107, the barcode reader 50, the lamp 53, and the speaker 52. The terminal device 12 controls the display 90, the printer 207, the barcode reader 91, the lamp 93, and the speaker 92. The displays 51 and 90 and the printers 107 and 207 are used to output the parts replenishment timing, parts replenishment request information, status information, and the like. The bar code readers 50 and 91 are used cordlessly. The network 10 includes an intranet that connects a production line and a warehouse. An information reading sensor 75 for reading the identification information of the part is disposed on the part conveyance path between the production line and the warehouse. This number and arrangement location are arbitrary. The read identification information is transferred to the server 15 through the network 10. FIG. 2B shows a detailed hardware structure of the terminal devices 11 and 12. Since the internal configurations of the terminal apparatuses 11 and 12 are substantially the same, only one terminal apparatus 11 will be described.

  The internal bus 120 of the terminal device 11 includes a CPU (Central Processing Unit) 122, a ROM (Read Only Memory) 123, a RAM (Random Access Memory) 124, an HDD (Hard Disk) 125, an input / output interface 126, A network interface 121 is connected. The input / output interface 126 is connected to the mouse 103, the display 51, the keyboard 106, the printer 107, and the barcode reader 50. Further, the lamp 53 and the speaker 52 are connected to the input / output interface 126. The arithmetic processing unit 20 illustrated in FIG. 1 includes a CPU 122, a ROM 123, a RAM 124, and the like. The storage device 30 illustrated in FIG. 1 includes a ROM 123, a RAM 124, and an HDD 125. The computer program executed by the CPU 122 is stored in the ROM 123 or loaded into the RAM 124 as appropriate.

Is done.

FIG. 3 is an explanatory diagram showing a specific example of the system of the present invention.
As shown in the figure, a work table 61 is arranged on the production line 60, and an operator 62 assembles a product using a part 63. The shelf 65 accommodates parts 70 to be supplied to the production line. A barcode is printed on the component 70 as shown in the lower figure. Here, an example in which the barcode is optically read by the barcode reader 50 is shown. However, for example, wireless reading of identification information using an IC tag is also possible. Optical reading of two-dimensional barcodes is also possible. The output of the barcode reader 50 is acquired by the terminal device 11 and transferred to the server 15. The terminal device 11 displays a component replenishment time, status information, and the like on the display 51 arranged in the production line 60. In addition, a speaker 52 and a lamp 53 are provided in order to notify the worker 62 of the arrival of the supplemental parts.

  On the other hand, on the warehouse side, replenishment parts 81 are stocked on shelves provided in the warehouse 80. The parts 81 are picked up from the warehouse 80 and transported toward the production line 60 using the transport device 76. The processing result is input to the terminal device 12 using the barcode reader 91 when picking up a component. When the barcode attached to the component 81 is read by the barcode reader 91, this information is input to the terminal device 12. The terminal device 12 controls the display 90, the speaker 92, or the lamp 93. The display 90 displays replenishment time, parts replenishment request information, status information, and the like. In addition, when there is a request for replenishment of parts, the speaker 92 is sounded or the lamp 93 is lit to call the warehouse manager's attention. In addition, an identification information sensor 75 is arranged on a conveyance path through which the component conveyance device 76 passes in order to read a barcode of the component 77 loaded on the conveyance device 76. This output is directly transferred to the server 15 by radio, for example.

  The system configured as described above generally operates as follows. First, in the production line 60, for example, the operator 62 operates the barcode reader 50 to read the identification information of any part. When this identification information is transferred to the server 15, the server 15 reads the production plan data 33 and calculates the use schedule of the part. At the same time, the number of existing parts stored on the shelf 65 is checked. This is calculated from the production plan data 33 and information indicating the past replenishment time. Then, the existing number of parts and the use schedule of the parts are compared to calculate a time when a new part needs to be replenished. The calculated component replenishment time is displayed on the display 51 and the display 90 at the same time. At this time, the parts replenishment request information addressed from the production line to the warehouse is also displayed.

  The parts replenishment request information is information indicating that when and how many parts are requested to be replenished. In principle, all parts used in the production line are operated in the same way. However, for example, for a part group that is a plurality of parts supplied to the production line and is used together in the same product, the above operation may be performed for only one of the parts. That is, identification information attached to any part belonging to the group is acquired. Thus, when the replenishment time is calculated, the same replenishment time calculation process is automatically executed for all parts belonging to the group. There is no need to read the barcodes of all parts one by one. This can save labor in parts management. For the above operation, the data stored in the storage device 30 may be configured as follows.

FIG. 4 is an explanatory diagram of data stored in the storage device of the system of this embodiment.
FIG. 4A shows the contents of data in which the component identification information 31 and the component name 32 are associated with each other. Prepare this data for all parts used. Used for specific display of part names. FIG. 4B shows the contents of the production plan data 33. The production plan data 33 includes, for example, information such as how many products are produced on the operating day of the production line, and information such as product production plans for each time zone. FIG. 4C shows the contents of the part data 34 listing the parts and quantities used in the product. As shown in the figure, the part data 34 includes data of part names, identification information, and the number of used parts of all parts used for each product.

  With reference to the production plan data 33, information on how many products in a certain time zone are produced is extracted, and with reference to the part data 34, the parts and quantities used for the product are read out. Thereby, the use schedule of each component can be calculated. FIG. 4D shows the contents of the calculated use schedule 36. The use schedule 36 includes data such as a part name, part identification information, and how many parts will be used by when. FIG. 4E shows the contents of the existing number 37 of parts. This is data that is calculated at the same time when the component replenishment time is calculated. It includes information indicating the part name, the part identification code, and the number of parts actually remaining. FIG. 4F shows the contents of the replenishment time 38. It includes information indicating the part name, identification information, and date and time when the part should be replenished. FIG. 4G shows the contents of the part group data 41. Here, for example, an identification information list of a group of parts used for the same product is included. As a result, when the replenishment time is calculated for any of these components, the replenishment time can be automatically calculated for all the parts belonging to the group at the same time.

  Next, the function of each means in the arithmetic processing unit 20 of the server 15 will be described. The identification information acquisition unit 21 shown in FIG. 1 has a function of acquiring identification information 72 attached to a component supplied to the production line 60 through the network 10 or the like. The identification information 72 is read by the barcode reader 50 and transferred to the server 15 through the terminal device 11. The use schedule calculation unit 22 reads the production plan data 33 of the product using the part specified by the identification information 72. Then, the use schedule of the part is calculated. The existing number calculating means 23 has a function of calculating the existing number of parts housed in a shelf 65 or the like prepared for supply to the production line 60.

  The replenishment time calculation means 24 compares the existing number of parts with the planned use of the parts, and predicts when the parts will be insufficient. As a result, the time when the parts need to be replenished is calculated. For example, it is assumed that the number of existing parts becomes 0 after 3 days. In this case, the time may be calculated such that a new part is replenished after two days. The number of replenishments for one time may be determined in advance for each part. Further, when the number of existing parts becomes one day, the calculation may be performed based on a rule that parts for two days are always prepared. The output control means 25 has a function of controlling the output of the calculated parts replenishment timing, replenishment request information, status information, etc. to the display and other output means. Further, the output control means 25 has a function of controlling to output past replenishment time calculation records of parts having a predetermined relationship with the parts specified by the identification information. For example, all the parts used on the same production line may be output to the display at the same time. Moreover, all the parts used for a specific product may be output to the display. Further, the parts may be listed and output in the order of replenishment request. The warehouse management unit 26 functions to calculate the number of remaining parts in the warehouse when the parts are unloaded from the warehouse, compare it with the appropriate inventory quantity, and maintain the appropriate inventory. Since the parts ordering process is executed automatically, the burden on the warehouse manager can be reduced.

FIG. 5 is an explanatory diagram of an output example displayed on a display or the like by the output control means.
FIG. 5A shows the output contents of the replenishment time 38 and the replenishment claim information 42. A table as shown in this figure is displayed on the display. Here, a list of all parts for which replenishment is requested is displayed in the order of request. From the left, the output is the part name, part code, replenishment deadline, replenishment number, and elapsed time. The replenishment deadline indicates the date and time to be replenished. The replenishment number is the number of parts that need to be replenished. These constitute replenishment claim information. By transmitting this replenishment request information to the terminal device on the warehouse side and displaying it on the display arranged on the warehouse side, the intention of the replenishment request is automatically communicated to the manager of the warehouse. The replenishment request information is displayed immediately after the part identification information is read on the production line side.

  The manager on the warehouse side starts work so that the parts are transported and delivered to the production line by the replenishment deadline included in the replenishment request information 42. However, when the replenishment request information is newly displayed or updated, if the manager on the warehouse side does not monitor the display, the work start timing is delayed. Therefore, an output device other than the display is used together to alert the administrator. The speaker 92 emits a certain alarm sound. The lamp 93 blinks to alert a remote place. In addition, it is preferable to output status information together with replenishment request information to the display.

  FIG. 5B shows the contents of the status information 44. The status information 44 includes, for example, the display of the part name of the part for which replenishment is requested and the processing executed for the part. “Billing acceptance” is displayed as “−” before the billing is accepted after the supplementary billing information is displayed on the display, and “◯” when the billing is accepted. “Picking complete” is displayed as “-” after the request is received and before the picking of the part is completed in the warehouse, and “◯” is displayed when it is completed. “Transferring” changes the display from “−” to “◯” when a transport vehicle that transports parts from the warehouse to the production line passes through a predetermined location. “Arrival” is changed from “−” to “◯” when the parts are transferred from the transport vehicle to the shelf and replenishment is confirmed. Since this status information can be used for parts conveyance and replenishment result management, it is preferable to store the status information in the storage device 30 as it is.

  For example, the status information 44 is sequentially updated by the following operation. First, when a manager on the warehouse side confirms a replenishment request for parts, information to that effect is input to the terminal device 12. This can also be input using the keyboard or mouse of the terminal device 12. However, a simpler method can be adopted. When the barcode of the part is read by the barcode reader for request reception, the request reception notification is automatically transmitted to the server 15. Even when picking is completed, the barcode of the picked component may be read with a barcode reader for notifying the completion of picking. While the parts are being transported by the transporting vehicle, the information reading sensor 75 shown in FIG. 3 detects the passage of the transporting device 76 and reads the barcode of the part 77 loaded thereon. As a result, the server 15 is notified of the information that the conveyance is in progress. When a part arrives at the production line, the bar code of the arrival part may be read using a bar code reader for arrival confirmation.

  Control is performed so that the status information shown in FIG. 5B is output from immediately after the supply of the component replenishment request information shown in FIG. 5A until the completion of the supply of the component. The corresponding status information should be deleted at the same time as the replenishment is completed. In addition, for example, an elapsed time display is included in order to confirm a response until the replenishment of parts is completed after the replenishment request information is output. For example, the display portion of the elapsed time may be changed from blue to yellow to red over time. Thereby, for example, it is possible to call attention to a component whose replenishment deadline is approaching. Such an elapsed time display may be included on the state information side. Display rules may be freely determined.

FIG. 6 is an operation flowchart of the server 15.
An example of the computer program of the server 15 will be described with reference to FIG. First, in the production line 60, the worker 62 proceeds with product assembly work, and manages replenishment of parts at a predetermined timing. For this, the identification information of any part stocked on the shelf 65 is read using the barcode reader 50. The identification information is transferred from the terminal device 11 to the server 15. The identification information acquisition means 21 of the server 15 acquires the identification information in step S11 and starts processing for replenishment request. The identification information acquired by the identification information acquisition unit 21 is passed to the use schedule calculation unit 22.

  In step S <b> 12, the use schedule calculation unit 22 reads the production plan data 33 in the storage device 30. In step S13, information capable of calculating the use schedule of the corresponding part is extracted from the production plan data. For example, the expected number of use for two days from that day is obtained. Next, in step S14, the existing number calculating means 23 calculates the number of parts remaining in the current production line. The existing number can be calculated from the number of parts that existed on the shelf at the start of production, the number of parts that have been used in production so far, and the number of parts that have been replenished. In step S15, the replenishment time calculation means 24 compares the scheduled use of the part with the existing number and calculates when the part should be replenished.

  In step S16, a replenishment time calculation record of related parts is read. Of those stored in the replenishment time 38 of the storage device 30, the one currently requested for replenishment is read. This is taken out, the process proceeds to step S17, and a replenishment claim information list as shown in FIG. 5 is generated. In step S <b> 18, the output control unit 25 transfers the supplement request list to the terminal device 11 and the terminal device 12. The terminal device 11 displays the list on the display 51, and the terminal device 12 displays the list on the display 90. Furthermore, the terminal device 12 on the warehouse side turns on the lamp 53 in step S19. In step S <b> 20, the warehouse-side terminal device 12 outputs a warning sound using the speaker 52. Thereafter, the process proceeds to step S21 to start displaying elapsed time. The elapsed time is sequentially updated with reference to the clock.

FIG. 7 is a flowchart of the elapsed time display control operation.
In step S31, the output control means 25 sequentially reads the time data of the system clock, and in step S32, selects the display of the elapsed time and its display color. The elapsed time is displayed as the time from when the supplementary billing information list is transmitted until the current time. The display color is blue for an elapsed time, for example, within 6 hours, yellow for more than 6 hours and up to 10 hours, and red for 10 hours or more.

FIG. 8 is a flowchart of the update control operation for the state information 44.
First, when the replenishment request information list is displayed on the display 90 on the warehouse side, the manager executes a replenishment request information confirmation process in step S41. Thereby, in step S42, the state information is rewritten such that the confirmation process is completed. Next, the manager of the warehouse 80 picks up the necessary number of parts stacked on the shelf. At the end of the pickup, for example, the bar code reader 91 is operated again. As a result, the process proceeds from step S43 to step S44, and the status information is updated such that the pickup is completed. Further, when the part is placed on the transport device 76 and transport is started, the identification information sensor 75 reads the identification information of the part. Thereby, the process proceeds from step S45 to step S46, and the state information is updated. Finally, when the conveying device 76 arrives at the production line 60 and stores the parts on the shelf 65, the worker 62 on the production line operates the barcode reader 50 and executes a confirmation process in step S47. In step S48, the corresponding part of the supplementary billing information list displayed on the display 51 or 90 is deleted. The display method of this status information and the change method thereof are arbitrary. Change characters, symbols, colors, blinking display, enlarged display, etc. according to certain rules. The certain rule is a rule indicating a correspondence relationship between the urgency level and the display method.

FIG. 9 is a flowchart showing the processing operation of the component group.
When each part is handled as a group, the processing shown in this figure is executed. First, in step S51, the component group data 41 is referred to using the identification information acquired by operating the barcode reader 50 as a key. If the component group data includes identification information of the corresponding component, the identification information of all components belonging to the component group is extracted one by one (step S52). Then, in the next step S53, a replenishment time calculation process is executed for all parts. As a result, it becomes possible to read the identification information of one component and manage all the components.

FIG. 10 is a flowchart of the parts management operation in the warehouse.
First, in step S61, it is assumed that parts are picked up at the warehouse based on replenishment request information. At this time, the remaining inventory number is calculated by subtracting the number of parts picked up. In the next step S62, the stock quantity is compared with the appropriate stock quantity. The appropriate inventory quantity is determined for each part in advance. In step S63, if the inventory quantity is lower than the appropriate inventory quantity, it is determined that the order is due. If the stock quantity is equal to or greater than the proper stock quantity, the process is terminated. In step S64, a part ordering process is executed. This makes it possible to automatically place an order for warehouse parts and secure an appropriate inventory.

  As described above, in the present invention, when the identification information attached to a part is read, the replenishment time of the part at that time is calculated. The timing for acquiring the identification information is arbitrary. The parts may be supplied immediately before being supplied to the production line or after being supplied to the production line. As the information reading means for reading the identification information, an arbitrary means such as an optical one, a magnetic one, a mechanical one, or an electromagnetic wave can be used. The server may acquire identification information through the network. The production plan data of a product using a part may be anything as long as it displays the use schedule of the part. In the so-called Kanban system, it is only necessary to have production plan data that has been finalized (closest to the present) for a short period of time. The part use schedule calculated based on the production plan data is preferably specific numerical data in which the relationship between the passage of time and consumption is clarified. Thereby, the replenishment time of components can be calculated accurately.

  It is desirable that the existing number of parts in the production line is the exact number of parts prepared in the production line when the use schedule of the parts is calculated. When calculating the replenishment time of parts, it is preferable to calculate according to a rule that a predetermined number of replenishments are required a predetermined time before the time when parts are actually insufficient. The output device that is controlled by the output control means and outputs a part replenishment request or the like is preferably arranged at a place where a manager of the production line or a person in charge of accepting a part replenishment request can monitor. The output device may be a display that displays image information, a screen, a printer that prints on paper, a speaker that outputs information by voice, and the like. The output control means may simultaneously control a plurality of output devices and output a component replenishment request to a plurality of locations.

  When predicting the replenishment time of one part, it is convenient if the replenishment time of other parts having a predetermined relationship can be calculated simultaneously. The method for selecting parts having a predetermined relationship is arbitrary. Although it may be specified manually by operating the computer, it is preferable that it is automatically related in advance. When a plurality of parts are handled as a group, the relation between the parts is arbitrary. A plurality of parts used for the same product and a plurality of parts used for a plurality of products shipped in combination have a great effect when grouped. The identification information is preferably different for each part. For example, the grouped parts may share part of the identification information or add information indicating that they belong to the same group.

  When requesting replenishment of parts, a predetermined number is designated and charged. This number may be appropriately determined according to the criteria such as how often replenishment is requested and how many parts can be stocked on the production line. The display method of the component replenishment time display, the component replenishment time calculation record display, the component replenishment request information, the status information, etc. is arbitrary. What is necessary is just to display a required matter by arbitrary expressions on an output device.

  The part status information such as picking up and transporting may be displayed in letters or symbols. When the component replenishment request information is output to the output device, the component status information is automatically displayed thereafter. The information reading means is also used at the end of component replenishment. It is possible to scan and input a barcode having the meaning of completion of replenishment. This barcode may be printed on a delivery slip or the like, for example. It is also possible to read and input the identification information of the corresponding part. In any case, it is preferably input during the component replenishment confirmation process.

  A conveyance path for conveying supplemental parts to the production line is provided, for example, between a warehouse for storing the parts and the production line. The structure of this conveyance path is arbitrary. The status information can be updated by reading the identification information of the supplementary part in a contact or non-contact manner at any location on the transport path. The status information may be updated by, for example, a process of adding information such as where the supplemental parts are present and when they arrive at the production line.

  With the above system, the parts replenishment claim process can be simplified and the communication work can be automated. The equipment can be used with inexpensive bar code readers and general-purpose board computers, thus reducing costs. Moreover, the processing can be speeded up compared to the conventional method. Moreover, since the proper parts can be supplied by operating the system, the in-process inventory can be reduced. Furthermore, by automating the liaison work, it is possible to eliminate parts delivery mistakes and reduce the man-hours for parts replenishment request paperwork. In addition, status information such as charged, urgent, in-delivery, and received can be displayed at all times, so that reliable and reliable parts management can be performed.

  Note that the computer program executed by the arithmetic processing unit may be modularized in units illustrated in functional blocks, or may be integrated by combining a plurality of functional blocks. Further, the above computer program may be used by being incorporated into an existing application program. The computer program for realizing the present invention can be recorded on a computer-readable recording medium such as a CD-ROM and installed in an arbitrary information processing apparatus for use.
