BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an online sorter device for sequentially distributing printed sheets discharged from a printing device such as a stencil printing device to a plurality of stacked bins for collating or sorting. Regarding

[0002]

2. Description of the Related Art Printed paper discharged from a printing machine or copied paper discharged from a copying machine is automatically distributed and stored in a plurality of storage shelves (hereinafter referred to as "bins"). A sorter device that collates with is well known. As such a sorter device, for example, JP-A-60-
In Japanese Patent Laid-Open No. 248566 and Japanese Patent Laid-Open No. 5-318899, a sorter device equipped with a bin unit configured by stacking a plurality of bins is connected to a sheet discharge port of a printing device, and the bin unit of the sorter device is vertically moved. A so-called "bin unit lifting type" on-line sorter device that reciprocates is shown.

When the above-mentioned online sorter device is connected to a stencil printing device of plate making and printing type to perform a collating operation, generally, in the sort mode, when the bin unit is raised or lowered, printed sheets are put in each bin. A system is adopted in which the bin units are sequentially stored and the bin unit is lowered or raised while a document is changed and a plate making process for a new master is being performed. These methods are so-called "one-way sorting" in which the storage operation is performed only when the bin unit is raised or lowered.

Conventionally, the operation of lowering or raising the bin unit for returning the home position to the home position, in which the operation of storing the paper in the bin is not performed, is performed within the time of the plate making process, and is a predetermined constant value. It was designed to operate at speed and the operator could not change that speed. When the online sorter is used by connecting it to the stencil printing machine, a so-called "continuous mode" for the purpose of preventing backslip in addition to the general sort mode for collating A "group mode" for dividing the printed matter into a plurality of groups can be selected.

In the stencil printing machine, when printed matter immediately overlaps on the discharge tray, the ink on the image side of the printed matter underneath is transferred to the back side of the printed matter above it, so-called back-sliding problem occurs. I have something to do. Therefore,
It is the "continuous mode" that uses multiple bins of the online sorter device to gain time until the printed materials overlap each other, and tries to prevent backsiding, and this also ensures that one-way sorting is always performed. It has become. That is, this "continuous mode" is a mode in which a large number of printed materials having the same image are sequentially and repeatedly stored in the bin of the sorter by one-way sorting even if a new original is not made. It is also possible to divide the printed matter into a plurality of groups by performing the same operation as in the "continuous mode", which is the "group mode".

In the conventional online sorter apparatus, the descending or ascending speed for the bin unit to return to the home position is constant even in the "continuous mode" and the "group mode", and moreover, in the sort mode. It was set to the same speed as if.

In the "continuous mode" for preventing backslipping, for example, in the case of a sorter having 20 bins, the printed matter will inevitably overlap with the 21st sheet. In the case of paper with poor ink absorption or a large number of solid images, it is desirable to secure a time of several minutes as the time interval until the printed matter overlaps. If the printed material is discharged at the discharge speed of sheet / minute, the discharging operation to 20 bins is only 2
It ends in 0 seconds.

Therefore, for example, in the technique disclosed in Japanese Patent Application Laid-Open No. 6-32039, the printing apparatus is temporarily stopped during the discharge of the 20th to 21st sheets, and the bin unit of the sorter apparatus is set to the home position during that period. It is descending or raising to return to the position.

[0009]

The printed paper discharged from the paper discharge port of the stencil printing machine through the belt conveying device and onto each bin of the sorter device depends on the kind, thickness, size, etc. of the paper, or Depending on the degree of solidity of the printed image, the discharge speed of the printed paper discharged onto the bin may vary, which may cause a phenomenon in which the leading end of the printed paper slightly pops out on the bin. As shown in FIG. 8, when the pop-out amount varies and becomes large, the printed paper Pa does not return to the bin 51, which causes a problem that the paper alignment on the bin 51 deteriorates. It was In the same figure, the symbol a indicates the amount of paper popping out in the above-mentioned trouble.

If the discharging speed is set to a small value in order to prevent the paper from popping out, the printed paper Pa does not completely reach the bin 51 and the printed paper Pa is not completely delivered to the bin 51, as shown in FIG. A trouble phenomenon of "remaining trailing edge of paper" in which the trailing edge remains outside the bin 51 occurs, and in this case also, the printed sheet Pa does not return to the bin 51, and the alignment of sheets on the bin 51 is poor. It was a problem of becoming. In the figure, reference numeral b indicates the remaining amount of the trailing edge of the sheet in the above-mentioned trouble.

In the above technique for preventing backslipping, if the moving speed at the time of lowering or ascending for returning the bin unit to the home position is high, it is not possible to take a sufficient time interval for drying the image of the printed matter. There is a problem.

In view of such a problem, as a measure against the above-mentioned problems, we have detected the size of the paper conveyed to each bin and automatically based on the detection data the conveyance speed of the belt conveyance device. A new technology of controlling is under development.

By the way, on the other hand, we have
After storing the printed paper in each bin, if the moving speed of the descending or ascending for returning the bin unit to the home position is increased, an appropriate vibration is given to each bin and the part that has jumped out of the bin It was discovered that the printed sheets of paper return to the top of the bin along the inclination of the bin, which eventually leads to better alignment of the paper on the bin. However, on the other hand, if the moving speed is increased, there is a problem that noise and vibration of the sorter device increase. By increasing the moving speed,
On the one hand, there are advantages and disadvantages such as improved paper alignment, and on the other hand, problems such as noise and vibration problems. We end up with the question of whether to make adjustments.

Therefore, in order to solve such a problem, the present invention secures sheet alignment on the bin and increases noise and vibration in an online sorter device used particularly by connecting to a stencil printing device. It is an object of the present invention to provide an improved sorter device capable of coping with the above.

Next, the main control configuration for controlling the operations of the stencil printing apparatus 1 and the sorter apparatus 2 will be described with reference to FIG. In the figure, reference numeral 3 is a print control device and reference numeral 4
Indicates a sorter control device, respectively. The print control device 3 and the sorter control device 4 are electrically connected to each other and send and receive various command signals, on / off signals, and data signals. The print control device 3 and the sorter control device 4 both include a microcomputer (not shown), and
It has a PU (central processing unit), an I / O (input / output) port, a ROM (read-only storage device), a RAM (readable / writable storage device), etc., and is connected by a signal bus. Print control device 3 and sorter control device 4
Is provided on a board (not shown) provided in the machine body portion 10 of the stencil printing apparatus 1.

The print control device 3 is electrically connected to the operation panel 80, the paper size detection sensor 5 and the bin unit ascending / descending speed data memory 6 and has a command signal and / or an on / off signal or the like. Sending and receiving data signals. That is, various keys, ten keys 81, print start key 82, mode selection key 83, speed up key 8
The data signal and the on / off signal from the speed down key 86 and the speed down key 86 are transmitted to the print control device 3. The print control device 3 determines each L of the LED lamp group 84 in the display device such as the LED based on the mode signal from the mode selection key 83.
A signal for turning on the ED lamp is transmitted to a power supply unit (not shown) of each LED lamp, and the mode signal is transferred to the sorter control device 4. The print control device 3 transmits a signal for turning on a lamp of a predetermined level of the LED 87 to a power supply unit (not shown) of the LED 87 based on the moving speed setting signal from the speed up key 85 and the speed down key 86, and The moving speed setting signal is transferred to the sorter control device 4. As will be described later, the print control device 3 supplies a signal for turning on the heavy duty LED lamp 88 based on the heavy duty loading signal from the heavy duty loading sensor 8 transferred from the sorter control device 4 to a power supply unit (not shown). No) to send. on the other hand,
The paper size detection sensor 5 transmits a paper size signal to the print control device 3. The print control device 3 transfers the paper size signal to the sorter control device 4.

The ROM in the print control device 3 is provided with a bin unit ascending / descending speed data memory 6, and as will be described later, a program relating to control of the moving speed of the bin unit 50, moving speed data and the like are stored in advance. Remembered The print control device 3 operates such as starting, stopping and timing of each device such as the document reading unit 30, the plate discharge unit 19, the plate making unit 21, the paper feed unit 28, the print unit 27, the paper discharge unit 18 of the stencil printer 1. Although the entire system is controlled, its illustration is omitted to clarify the features of this embodiment. Print control device 3
The internal RAM temporarily stores the calculation result of the CPU, and stores the data signal and ON / OFF signal input from the various keys at any time.

The sorter control device 4 includes a paper passage sensor 60, a bin unit lifting speed sensor 63, and a bin unit home position sensor 7 in addition to the printing control device 3 described above.
Is electrically connected to and receives on / off signals and data signals from these. On the other hand, the sorter control device 4 is electrically connected to the motor 62 for raising and lowering the bin unit, the stapler device 9 and the intermediate conveyance device 52 which will be described later, and transmits a command signal which will be described later to them based on the above-mentioned respective signals. is doing.

That is, the paper passage sensor 60 detects the passage of the printed paper Pa each time it passes through the paper receiving port 59, and sends a paper passage signal to the sorter control device 4. The sorter control device 4 transmits a drive command signal to the motor 62 for lifting the bin unit based on the paper passage signal. The drive command signal is the printed paper P.
The drive operation of the motor 62 is controlled so that the lead cams 57a and 57b rotate exactly one revolution each time a passes one sheet of the sheet receiving port 59, whereby the bin 51 is raised by one stage ( Or descend). The bin unit ascending / descending speed sensor 63 is provided on the shaft 56 of the ascending / descending means 69.
The rotational angular velocities of a and 56b are detected, and the speed signal is transmitted to the sorter control device 4. The bin unit home position sensor 7 detects the home position of the bin unit 50 and sends the position signal to the sorter control device 4.
When the speed signal is transmitted to the print control device 3, it is collated with the moving speed data in the bin unit ascending / descending speed data memory 6, and the sorter control device 4 descends or returns to the home position of the bin unit 50. The rising movement speed is controlled and corrected so as to match the predetermined speed data in the bin unit lifting speed data memory 6.

The sorter control device 4 controls the entire system relating to operations such as starting and stopping of the sorter device 2. The sorter control device 4 has a function of a moving speed changing unit that changes the moving speed based on the moving speed setting signal transferred from the print control device 3. More specifically, the sorter control device 4 reduces the moving speed when the continuous mode or the group mode is selected to be lower than the speed for the sort mode when the sort mode is selected, and sets the desired continuous mode ( Function for speed for group mode),
When the sort-and-staple mode is selected, a function of increasing the moving speed to a speed for the sort-and-staple mode by increasing it from the speed for the sort mode, and the paper size detection sensor 5 detect that it is a postcard size. When the continuous mode or the group mode is selected, the moving speed is further reduced to the postcard speed by further reducing the moving speed from the desired continuous mode (group mode) speed, and the paper size input. Means (not shown)
When the postcard size is input by, and the continuous mode or the group mode is selected, the moving speed is further reduced from the desired continuous mode (group mode) speed to be the postcard speed. And a sorter device connected in series is connected to the stencil printing machine 1, and when the continuous mode or the group mode is selected, the moving speed is set to the desired continuous mode (group mode) described above.
It also has the function of increasing the continuous use speed by increasing the speed.

Here, a numerical example (required time described later) for the sorter control device 4 to change the moving speed is listed as follows for each mode.

Level of movement speed Level 7 to Level 1 Speed for sort mode ……………………………… 20 to 40 seconds Speed for continuous mode (group mode) …… 60 to 120 seconds Sort and staple mode Speed for use ………… 10 to 20 seconds Speed for postcards ………………………………………… 120 to 180 seconds Speed for heavy use ……………………………………………… 30 ˜60 seconds As the multiple continuous speed, the speed is increased to a speed higher than the speed for the continuous mode (group mode) and lower than the speed for the sort mode.

As the method of increasing / decreasing the moving speed by the sorter control device 4, the same method as the method of sliding the entire range of level 7 to level 1, the speed for sort mode and the speed for continuous mode (group mode) are used. There are two ways to increase or decrease within the range (change from standard level 4). In the latter case, the speed range is, for example, 10 to 180.
Can be set to seconds.

Further, a ROM (not shown) in the sorter control device 4 stores in advance programs, data and the like for executing the operation in each mode described later. The RAM in the sorter control device 4 temporarily stores the calculation result of the CPU, or the data signal or ON / OFF signal transferred from the print control device 3 or the data signal or ON / OFF signal transmitted from each sensor. Memorize the signal at any time.

Next, a series of operations when the stencil printing apparatus 1 and the sorter apparatus 2 are connected will be described. First, the sort mode will be described with reference to FIGS. Here, it is assumed that 20 copies of printed matter are to be printed per page in an original of 5 pages, for example. First, the operator sets five originals (not shown) on the original tray 29a of the ADF 29 of the stencil printer 1 and then presses the mode selection key 83 once to select the sort mode. Normally, as described above, the non-sort mode is set, but when the mode selection key 83 is pressed once to select the sort mode, the LED lamp 84a for displaying the sort mode is turned on.

Next, 20 which is the number of sheets to be printed is input with the ten keys 81. Since the device is used in the office, and it is neither urgent nor automatically stapled after printing, the speed down key 86 is pressed to move the bin unit 50 downward or upward for returning to the home position. The speed is set from the standard speed "level 4" to the lower "level 2".

Next, the operator presses the print start key 8
When 2 is pressed, the plate cylinder 11 having the used master S of the previous plate wound around the outer peripheral surface is rotated in the counterclockwise direction by the driving means, and the used master S is separated by the peeling roller pair 19b. , 19c, the outer peripheral surface of the plate cylinder 11 is peeled off.
The used master S that has been peeled off is a pair of peeling rollers 19
It is conveyed by b and 19c, and is discarded inside the plate discharge box 19a. After that, the plate cylinder 11 further rotates and stops at the plate feeding position shown in FIG. When the plate cylinder 11 stops at the plate feeding position,
The master clamper 25 is rotated in the clockwise direction by the opening / closing means (not shown), and the plate cylinder 11 enters the plate feed standby state shown in FIG. 1 to complete the so-called plate discharging process.

A plate making process is performed in parallel with the plate discharging process described above. The image of the first original sent by the ADF 29 is read by the original reading unit 30 and converted into an image signal. In the plate making unit 21, the thermal head 22 selectively generates heat based on the image signal to perform punching and plate making on the master S. The master S that has been prepressed has a pair of conveying rollers 24a, 2
Master clamper 25 expanded at the plate feeding position by 4b
The front end of the master S, which has been subjected to plate making, is locked by the master clamper 25 and wound around the outer peripheral surface of the plate cylinder 11.
When it is determined that the set amount of the master S that has been prepressed is completed by rotating the platen roller 23 by a predetermined number of steps of the stepping motor (not shown), the rotation of the platen roller 23 is stopped and the master S that has been prepressed is stopped. The plate making process ends when the trailing end is cut by the cutter portion 26 and the master S for one plate that has been already made is completely wound around the outer peripheral surface of the plate cylinder 11.

Then, the printing process is started. At this time, the bin unit 50 is most lowered and returned to the home position. That is, the uppermost bin 51 a of the bin unit 50 faces the sheet receiving port 59. First, the paper feed roller 15 conveys the uppermost first printing paper P on the paper feed tray 14 toward the feed roller pair 16a, 16b. The conveyed printing paper P is inserted between the plate cylinder 11 and the press roller 17 at a predetermined timing synchronized with the rotation of the plate cylinder 11 by the feed roller pair 16a and 16b. The press roller 17 that has been separated from the outer peripheral surface of the plate cylinder 11 moves upward, and is wound around the outer peripheral surface of the plate cylinder 11 that rotates in the clockwise direction.
When the printing paper P is pressed against the plate, the ink is transferred to the plate cylinder 1.
The image of the first original is printed by passing through the perforated portion of the master S, which has been plate-made, from an opening portion (not shown) of FIG. The printed paper Pa printed in this way is printed on the plate cylinder 1 by the paper ejection claws 18A of the paper ejection unit 18.
The sheet is separated from the outer peripheral surface of the sheet 1, is discharged onto the conveyor belt 18c, and is further conveyed to the intermediate conveying device 52 by the conveyor belt 18c while being sucked by the suction fan 18d.

As shown in FIG. 2, the printed paper Pa carried on the endless belt 53a of the intermediate carrying device 52 is carried to the paper receiving port 59 by the endless belt 53a while being sucked by the suction device 54. The printed paper Pa conveyed in this manner is discharged onto the uppermost bin 51a of the bin unit 50 facing the paper receiving port 59 at this time. Immediately after that, stencil printer 1
Thus, the second sheet is printed by the same operation as described above.
On the other hand, the first printed sheet (hereinafter referred to as "printed matter")
However, when the paper passage sensor 60 detects that the paper has passed through the paper receiving port 59, the sorter control device 4 causes the lead cams 57a and 57b to detect the detected signal.
By controlling the drive operation of the motor 62 so as to rotate just one revolution, the bin 51 of the bin unit 50 is raised by one stage. In this way, the second print is the bin unit 5.
0 is discharged onto the second-stage bin 51b.

In this way, the printed matter is sequentially transferred to the bin 51.
When the 20th printed material is discharged to the uppermost bin 51t of the bin unit 50, the printing operation of the stencil printing apparatus 1 is stopped. And the sorter device 2
In accordance with the command from the sorter control device 4, the motor 6
2 rotates the lead cams 57a and 57b in the opposite direction to the upward movement, whereby the bin unit 50 descends and returns to the home position. In this case, the moving speed for returning the bin unit 50 to the home position is selected as “level 2” by the moving speed input means of the operation panel 80 and is stored in the bin unit lifting speed data memory 6 in advance. “Level 2” is selected from among the values that are set, and the bin unit 50 descends relatively slowly and quietly.

In the meantime, in the stencil printing machine 1, A
The second document is sent from the DF 29 to the document reading unit 30,
The image of the second original is read by the original reading unit 30 and plate-made by the master S, and the master S that has already made the plate is the plate cylinder 11
The operation of being wound around the outer peripheral surface is performed. Bottle unit 5
When 0 descends at the moving speed of "level 2" and reaches the home position, the home position is detected by the bin unit home position sensor 7, and the print control device 3 detects two sheets by the stencil printing device 1 based on the position signal. The printing operation of the image of the original of the eye is started. Then, the printed material corresponding to the image of the second original is printed in the bin unit 50.
Is discharged onto the uppermost bin 51a, and the bin unit 50 is sequentially operated in the same manner as described above.

The moving speed for returning the bin unit 50 to the home position is as follows when the sort mode is selected in the sorter device 2 of the bin unit 50 having the 20-stage bins 51 as in this embodiment. The required time can be selected from the range of 20 to 40 seconds. That is, when the moving speed is converted into the time required for the moving distance per bin, 1 bin / 1.0
The range is from 1 second / 2.0 seconds.

Next, the sort and staple mode will be described (see claim 3).

Since the operation in each step of the stencil printing apparatus 1 using each mode described below is the same as that of the sort mode described above, the description thereof will be omitted as appropriate. When the operator presses the mode selection key 83 twice, the sort and staple mode display LED lamp 84b is turned on. Thus, when the sort and staple mode is selected, a command signal is transmitted from the sorter control device 4 to the motor 62, and the sorter control device 4 sets the moving speed for returning the bin unit 50 to the home position to the highest speed. It is automatically set to "Level 7". That is, when the sort and staple mode is selected, the sorter control device 4 increases the moving speed above the standard speed when the sort mode is selected. That is, in order to perform the stapling operation, the paper alignment of the printed matter on each bin 51 is very important. Therefore, the movement speed is increased and the vibration is utilized to automatically improve the paper alignment. is there.

However, when the standard paper is used and the solid portion of the image is small, the level of the moving speed selectively input by the moving speed input means is preferentially applied. ing. That is, the operator can press the speed down key 86 to change from "level 7" to "level 6" or "level 5". Besides, in the sort and staple mode, the moving speed may be automatically increased as compared with the case of the sort mode. For example, if the sort mode is 20 to 40 seconds, the sort and staple mode is 10 to 20 seconds.
The moving speed is automatically increased.

Next, the continuous mode will be described (see claim 2). This continuous mode is used, for example, for fine paper or PPC.
This is used when you want to print cleanly on paper, such as paper, where back-printing does not easily occur. For example, suppose that one manuscript sheet is used to obtain 50 printed materials without back-printing. First, the operator first receives the original tray 29 of the ADF 29 of the stencil printing machine 1.
Pressing the mode selection key 83 three times after setting one original document (not shown) on LEa displays LE for continuous mode display.
The D lamp 84c lights up. Next, after inputting 50, which is the number of sheets to be printed, with the ten keys 81, the speed down key 86 is pressed to change the moving speed to, for example, "level 3".
Set to. If the moving speed is not input without pressing the speed down key 86, the normal standard speed "level 4" is set in this case as well.

Then, the operator presses the print start key 8
When 2 is pressed, in the stencil printing apparatus 1, as in the case of the sort mode, the operation of each process is sequentially performed, starting from the plate discharging process, such as plate making, plate feeding, printing, and paper discharging. Then, the first printed material is the bin unit 50.
After the paper is discharged onto the uppermost bin 51a, the bin unit 50 moves up by one stage and the second printed material is transferred to the second bin 5a.
It is discharged on 1b.

In this way, the printed matter is sequentially transferred to the bin 51.
When the 20th printed material is discharged onto the lowermost bin 51t of the bin unit 50, the printing operation of the stencil printing apparatus 1 is stopped. In the sorter device 2, the motor 62 rotates the lead cams 57a and 57b in the direction opposite to the ascending direction based on a command from the sorter control device 4, whereby the bin unit 50 descends and returns to the home position. In this case, the moving speed is "level 3" according to the operator's instruction.
Is selected, and the robot descends at the selected moving speed.

During that time, that is, until the bin unit 50 descends and returns to the home position, the stencil printing machine 1 merely waits for the end of the descent, and the plate making process is not performed. As soon as the bin unit 50 returns to the home position, the initial position of the bin unit home position sensor 7 is detected, and the print control device 3 prints the image of the 21st document by the stencil printing device 1 based on the detection signal. Resume operation. Then, the 21st printed matter in total is discharged onto the uppermost bin 51a of the bin unit 50, and the 22nd sheet is stored on the second bin 51b in the same manner as described above. The printing operation is stopped again when the 40th sheet is discharged onto the lowermost bin 51t. Then, in the same manner as the above-described operation, the remaining 10 sheets are sequentially printed and sequentially discharged from the uppermost bin 51a to each bin 51.

However, it should be noted that in this continuous mode, the range of the moving speed of "level 3" selected according to the operator's instruction is different from the moving speed in the case of the sort mode described above. . That is, when the continuous mode is selected, the sorter control device 4
The moving speed is automatically reduced as compared with the case where the sort mode is selected. For example, "Level 7"
The moving speed of the bin unit 50 corresponding to "level 1" is in the range of 60 seconds to 120 seconds in the required time. Therefore, even if the highest speed "level 7" is selected in the continuous mode, the moving speed is only 1 bin / 3 seconds. This is because it takes time rather than the function of aligning sheets to prevent back-back, so execution of this function is prioritized, and the bin unit 50 is brought to the home position with low noise and low vibration. This is because it is better to restore it, and there is no stapling operation in the continuous mode.

Next, the group mode will be described (see claim 2). This group mode is used when the printed matter is grouped by the same operation as the continuous mode. Further, similarly to the continuous mode, it may be used when it is desired to perform clear printing on a printing paper such as a high-quality paper or a PPC paper, which is likely to cause back-back, so as to prevent back-back. For example, 2 for one document
Suppose you want to obtain 00 prints and 20 prints divided into 10 classes (groups). First, the operator first receives the document receiving tray 2 of the ADF 29 of the stencil printing machine 1.
When the mode selection key 83 is pressed four times after setting one original document (not shown) on 9a, the LED lamp 84d for displaying the group mode is turned on. Next, after inputting 20 (sheets) × 10 (group) which is the output condition to be printed with the ten keys 81, the speed down key 86 is pressed to set the moving speed to, for example, “level 3”. If the moving speed is not input without pressing the speed down key 86, the "level 4" of the normal standard speed is used in this case as well.
Is set to.

Then, the operator presses the print start key 8
When 2 is pressed, in the stencil printing apparatus 1, similarly to the operation in the continuous mode, starting from the plate discharging step, the plate making is sequentially performed.
The operation of each process such as plate feeding, printing, and sheet discharging is executed. Then, after the first printed material is discharged onto the uppermost bin 51a of the bin unit 50, the bin unit 5
0 goes up by 1 level and the second printed material is the second bin 51b.
Discharged on top. In this way, when the printed matter is sequentially discharged onto the bin 51 and the tenth printed matter is discharged onto the tenth bin 51j (not shown), the printing operation of the stencil printer 1 Is stopped. And the sorter device 2
In accordance with the command from the sorter control device 4, the motor 6
2 rotates the lead cams 57a and 57b in the opposite direction to the upward movement, whereby the bin unit 50 descends and returns to the home position. In this case, "level 3" is selected as the moving speed according to the instruction of the operator, and the moving speed is lowered at the selected moving speed.

During that time, that is, until the bin unit 50 descends and returns to the home position, the stencil printing machine 1 merely waits for the end of the descent, and the plate making process is not performed. As soon as the bin unit 50 returns to the home position, its initial position is detected by the bin unit home position sensor 7, and the printing control device 3 prints the image of the 11th original by the stencil printing device 1 based on the detection signal. Resume operation. Then, the eleventh printed sheet in total is discharged onto the uppermost bin 51a of the bin unit 50, and the twelfth sheet is stored on the second bin 51b in the same manner as described above. The printing operation is stopped again when the 20th sheet is discharged onto the 10th-stage bin 51j. In this way, the same operation as described above is repeated 18 times and the remaining 1
Eighty sheets are sequentially printed, and finally the uppermost bin 51a.
The printing operation ends when 20 sheets are discharged to the second stage bin 51b, 20 sheets to the 10th stage bin 51j (not shown), respectively.

However, even in this group mode,
The range of the moving speed of "level 3" selected according to the operator's instruction is different from the moving speed in the case of the sort mode as in the continuous mode. That is, when the group mode is selected, the sorter control device 4 automatically reduces the moving speed more than when the sort mode is selected. For example,
Bin unit 5 corresponding to "Level 7" to "Level 1"
The moving speed of 0 is in the range of 60 seconds to 120 seconds in the required time. Therefore, even if the highest speed "level 7" is selected in the group mode,
The moving speed is only bin / 3 seconds. This is because it takes time rather than the function of aligning sheets to prevent back-back, so execution of this function is prioritized, and the bin unit 50 is brought to the home position with low noise and low vibration. This is because it is better to restore it, and there is no stapling operation in the group mode.

Further, in this group mode, the bin unit 50 may be controlled to operate as follows, not limited to the above example. That is, similar to the above operation example, when the tenth printed material is discharged onto the tenth bin 51j (not shown), a predetermined time, for example, when the continuous mode is selected or in the above example The printing operation of the stencil printing apparatus 1 is stopped for the same time as the time required for the bin unit 50 to descend and return to the home position. After a predetermined period of rest, the printing operation of the stencil printing machine 1 is started,
The eleventh printed material is discharged onto the same tenth bin 51j (not shown). When the passage of the eleventh printed matter is detected by the sheet passage sensor 60 at the sheet receiving port 59, the sorter control device 4 causes the lead cams 57a and 57b to move in the direction opposite to the above-described direction based on the detection signal. By controlling the driving operation of the motor 62 so as to rotate exactly once, the bin 51 of the bin unit 50 can be controlled.
Is lowered by one step. In this way, the twelfth printed material is discharged onto the bin 51i (not shown) in the ninth stage of the bin unit 50. In this way, the printed matter is sequentially transferred to the bin 51.
When the 20th printed material is discharged to the uppermost bin 51a of the bin unit 50, the printing operation of the stencil printing apparatus 1 is stopped for the predetermined time. After a lapse of a predetermined time, the printing operation of the stencil printing apparatus 1 is started, and the 21st printed matter is discharged onto the same uppermost bin 51a. In this way, the 21st printed matter is fed into the paper receiving port 59.
When the paper passage sensor 60 detects the passage, the sorter control device 4 drives the motor 62 so as to rotate the lead cams 57a and 57b exactly once in the opposite direction to the above-described direction based on the detection signal. By controlling, the bin 51 of the bin unit 50 is raised by one stage. Then, the same operation as the above-described operation is repeated, the remaining number of sheets is sequentially printed, and finally 20 sheets are placed in the uppermost bin 51a, 20 sheets are placed in the second-stage bin 51b, ...
The printing operation ends when 20 sheets are discharged to the 0-th bin 51j (not shown). The predetermined time period is measured by an internal timer (not shown) provided in the print control device 3.

Postcards can be printed using the continuous mode, and the printed postcards can be distributed and discharged into the bins 51 of the bin unit 50 for storage (see claims 4 and 5). The operation is similar to that in the continuous mode described above. When printing on postcards, backlining is not allowed in particular.For example, if there is a backlining in the postmark section of the address or the postal code column, etc., it is only that, and the backlining part is corrected or the postcard itself is discarded. It wastes time and costs.

Therefore, the paper size detection sensor 5 shown in FIG. 6 provided on the paper feed table 14 of the stencil printing machine 1 detects that the card is a postcard size, and the mode selection key 83 selects the continuous mode. In this case, the sorter control device 4 reduces the moving speed from the standard speed "level 4" in the continuous mode to automatically set it to the lowest speed "level 1". Here, as an example of the postcard size, a postcard manufactured by 148 mm × 100 mm can be cited. Of course, even in this case, if the operator wants to print at "level 2", he / she can press the speed up key 85 to change to "level 2" below the standard speed "level 4" in continuous mode. is there.

Besides this, in the case of printing on a postcard, the moving speed may be automatically set lower than that in the continuous mode according to claim 2. In this case, it is 60 to 120 seconds in the continuous mode according to claim 2, but is 120 to 180 seconds in the case of printing on a postcard.

Printing on the postcard can of course be performed in the same manner as in the above example using the group mode described above.

In addition to the above example, when the postcard size is input by the paper size input means (not shown) provided on the operation panel 80 and the continuous mode or the group mode is selected by the mode selection key 83, The sorter control device 4 may reduce the moving speed from the standard speed "level 4" in the continuous mode to automatically set the minimum speed "level 1". Also in this case, similarly to the above example, if the operator wants to print at "level 2", the speed up key 85 is pressed to change to "level 2" below the standard speed "level 4" in continuous mode. Of course, it is possible. In addition to this, in the case of printing on a postcard, the moving speed may be automatically set lower than that in the continuous mode according to claim 2. in this case,
It is 60 to 120 seconds in the continuous mode according to claim 2, but is 120 to 180 seconds in the case of printing on a postcard.

Next, a modification of the above embodiment will be described with reference to FIG. 7 (see claim 6).

This modification is different from the above embodiment in that one sorter device 2A is further connected downstream of the sorter device 2 so as to be connected, and a plurality of images printed corresponding to one original image are printed. Connected to the sorter control device 4 to detect the overlap of the sorter devices 2 and 2A in order to sequentially distribute and eject one printed sheet for each bin over the two sorter devices 2 and 2A. Duplicated sensor 8 (see FIG. 6)
When the continuous mode or the group mode is selected by the mode selection key 83, the sorter control device 4 sets the moving speed to be lower than that when the continuous mode or the group mode according to claim 2 is selected. The only difference is that it has the function of further increasing the speed.

In this modification, the so-called "double station" is called, and two sorter devices 2 and a sorter device 2A having substantially the same configuration as the sorter device 2 are provided downstream of the stencil printer 1. It is connected in series to increase the number of bins and used as a 40-bin sorter.

At the lowermost part of the bin unit 50 of the sorter device 2, there is provided a multiplex transport unit 65 so as to face the downstream side of the intermediate transport device 52. The continuous transport unit 65 has a configuration similar to that of the intermediate transport device 52, is wound between a drive roller 65b connected to a drive motor (not shown) and a driven roller 65c, and has a plurality of openings (not shown). ), And a suction fan (not shown) that sucks air in the space inside the endless belt 65a and sucks printed paper (not shown) that is being conveyed onto the endless belt 65a. It is mainly composed of a suction device 66. The rear end of the multi-row transport unit 65 faces the sheet receiving port 67 of the sorter device 2A. The sorter device 2A includes a bin unit 70 in which a plurality of bins 71 for distributing and ejecting and storing the printed sheets conveyed by the multi-stage conveying unit 65 of the sorter device 2 according to a selected mode, and a bin unit 70. It is mainly composed of an elevating means (not shown) for elevating the unit 70. The lifting means has the same structure as the lifting means 69 of the sorter device 2. At a predetermined portion of the sorter device 2, a double-strip attachment sensor 8 for detecting the connection state between the sorter device 2 and the sorter device 2A is provided. The double attachment sensor 8 is an electric switch provided together with a communication line routed between the sorter device 2 and the sorter device 2A. Note that, in FIG. 7, the plate making unit 21, the plate discharging unit 19, and the like of the stencil printing apparatus 1 are omitted.

Next, a description will be given of the operation in the case of printing 50 sheets of printed matter by using the continuous mode in this "double-up" mode, for example, using one sheet of the original without back-printing.

First, the operator A of the stencil printing machine 1
When one mode of the document (not shown) is set on the document receiving table 29a of the DF 29 and the mode selection key 83 is pressed three times, the continuous mode display LED lamp 84c is turned on. Next, press the numeric keypad 81
Then, the speed down key 86 is pressed to set the moving speed to, for example, "level 3". If the moving speed is not input without pressing the speed down key 86, the normal standard speed "level 4" is set in this case as well.

The first to twentieth printed materials are discharged from the bin 51a of the first sorter device 2 to the bin 51t, and the bin unit 50 rises. Immediately thereafter, from the twenty-first sheet. The printed materials up to the 40th sheet are sequentially transported by the multiple-strip transport unit 65 and discharged from the bin 71a of the second sorter device 2A to the bin 71t. Here, when the 40th printed matter is sequentially stored by the bin unit 70 of the sorter apparatus 2A, the printing operation of the stencil printing apparatus 1 is stopped. Then, the bin unit 50 in the sorter device 2 and the bin unit 70 in the sorter device 2A slowly descend to return to the home position. Bin unit 5 in this case
Even if the moving speed for returning the home position of 0 and the bin unit 70 to each home position is higher than that in the case where there is no overlap, it is possible to obtain a sufficient time until the overlap of the printed matter. When it is detected that there is a multiple station, the multiple station LED lamp 88 is turned on, and the sorter control device 4 selects the continuous mode according to claim 2 in which the moving speed is not the multiple station. It slides to the higher speed side. For example, the bin unit 50 and the bin unit 7 corresponding to "level 7" to "level 1"
The moving speed of 0 is slid to the high speed side in the range of 20 bins / 30 seconds to 60 seconds. Also in this overlapped printing, it is of course possible to perform the same printing as described above in the group mode.

Note that the embodiment of the present invention is not limited to the "double station" of the modified example, but may be one in which three or more sorter devices, that is, a plurality of sorter devices, are connected and operated as necessary. .

In the above-mentioned embodiment and modification,
In the case of normal printing in the non-sort mode, all printed sheets Pa are discharged and stored in the uppermost bin 51a.

In the above-mentioned embodiment and modification,
The home positions of the bin units 50 and 70 are set to the uppermost bins 51a and 71 of the bin units 50 and 70, respectively.
Although the position a is opposed to the sheet receiving ports 59 and 67, the position is not limited to this, and the position where the lowermost bins 51t and 71t of the bin units 50 and 70 are opposed to the sheet receiving ports 59 and 67 is not limited to this. It may be. In this case, the bin unit home position sensor is the bin unit 5
It may be arranged so that the positions of the uppermost bins 51a and 71a of 0 and 70 can be detected.
This is the speed at the time of ascent for returning the bin units 50, 70 to their home positions.

[0110]

As described above, according to the first aspect of the present invention, the configuration and operation allow the user or operator to consider the thickness and type of printing paper, the size, the solidness of an image, and the like. If you want to improve the alignment of the paper on the bin, you can set the moving speed of the descending or ascending movement to return the bin unit to the home position to increase the speed of the paper using vibration. The alignment can be improved. On the other hand, in the case where low noise and low vibration are strongly demanded in the usage environment of the device, the moving speed can be set to be decelerated. In this way, the user or the operator can freely select and use the moving speed within a certain range, so that it is possible to respond to the needs of the user or the operator.

According to the second aspect of the present invention, when the continuous mode or the group mode is selected by the input operation of the continuous mode or the group mode input means, the moving speed varying means makes the input operation of the sort mode input means. Since the moving speed is automatically reduced compared to the case where the sort mode is selected by, the time for fixing the ink is gained and the ink slowly descends or rises.Therefore, a sufficient time interval for preventing backslipping is required. In addition to being obtained, it is possible to operate with low noise and low vibration.

According to the third aspect of the present invention, when the sort-and-staple mode is selected, high accuracy is required for aligning the sheets on the bin. Therefore, the moving speed varying means automatically increases the moving speed by the input operation of the sort mode input means as compared with the case where the sorting mode without staples is selected, thereby aligning the sheets on the bin, That is, the sort and staple mode can be executed with high accuracy.

According to the invention described in claims 4 and 5, the case where the paper is a postcard size and the case where the paper is a non-general paper,
Since the moving speed varying means automatically switches and controls the moving speed, in the case of a postcard that does not allow backlining,
Since it slowly descends or rises more slowly than in the case of general paper, it is possible to reliably prevent the occurrence of backsiding.

According to the sixth aspect of the present invention, since the total number of bins is multiple, the set value of the moving speed in the continuous mode or the group mode can be made larger than that in the case of one continuous line. . Therefore, when the sorter device is used in a cascade and the continuous mode or the group mode is selected by the input operation of the continuous mode or the group mode input means, the moving speed varying means,
Since the moving speed is further increased more than in the case of claim 2, the total time from the plate discharge by the printing device to the end of the collating operation by the sorter device can be shortened.
