FIG. 7 is a flowchart for explaining the operation, and FIG. 7 is a flowchart for explaining the stapling operation of the post-processing apparatus in FIG.

In FIG. 1, a plurality of bins 350 are arranged in a vertical direction, that is, in a direction orthogonal to the drawing, and are arranged so that their tips are directed upward. Paper P indicated by dashed line
Are sequentially discharged onto the bin 350 from the direction of the arrow A shown in the figure, and the rear end thereof contacts the fence 350a by its own weight and is aligned in the transport direction. The side fence shaft 401 of the fence unit (not shown) is arranged so as to extend in the direction in which the bins 350 are arranged, that is, in the up-down direction, and is movable in a direction perpendicular to the sheet discharging direction according to the size of the sheet P.

The staple unit 600 and the chuck unit 602 can be integrally moved in the direction in which the bins 350 are arranged. The staple unit 600 binds a sheet bundle P on the bin 350 with staples (staples). The chuck C of the chuck unit 602 reciprocates in the horizontal direction, moves from the home position a to the chuck position b, holds the sheet bundle P on the bin 350, and moves from the chuck position b to the staple position e of the staple unit 600. To the return position c on the bin 350.

Incidentally, the jogger unit 500 is provided with a sheet bundle P
The staple unit 600 and the chuck unit 602 can move independently of each other in the direction in which the bins 350 are arranged. This jogger unit 500
Is controlled to be located one or more bins below so as not to collide with the chuck unit 602 or the like.

The CPU 900 controls the sorting of the paper P on the bin 350, controls the horizontal movement of the side fence shaft 401 according to the paper size, controls the vertical movement of the staple unit 600 and the chuck unit 602, and controls the chuck C as described later. , And controls the holding and release of the sheet bundle P, and each drive is performed via a stepping motor or a solenoid. In FIG. 1, the sheet bundle P is chucked by the chuck C at the chuck position b and the staple unit 6 at the staple position e.
00, and is returned to the bin 350 by the chuck C at the return position c before the chuck position b. The home position a of the chuck C is set between the staple position e and the return position c, and as shown in FIG. 2, the chuck C is moved at the vertically movable position d between the home position a and the return position c. 602 is controlled to start moving up and down.

Next, the detailed structure of the chuck unit 602 will be described with reference to FIGS. The chuck unit 602 includes a mechanism W for reciprocating the chuck C in a horizontal direction, in addition to the chuck C for holding the sheet bundle P. A pair of upper and lower chuck levers 631 and 63 for holding and releasing the sheet bundle P are held on the chuck C.
0 is mounted so as to be openable and closable in the vertical direction. The upper chuck lever 631 is connected to the lever 6 via a spring 634.
33, and the chuck solenoid 635 rotates the lever 633 to thereby rotate the upper chuck lever 63.
1 and the lower chuck lever 630 open and close in the vertical direction.

The spring 636 is provided to assist the upper chuck lever 631 and the lower chuck lever 630 in opening in the vertical direction. Further, as shown in FIG. 5, the levers 631 and 630 of the chuck C are arranged at an angle of 30 ° with respect to the horizontal. This is because the bin 350 is inclined to align the sheet bundle P in the transport direction. Because it is. The stapler 601 of the stapling unit 600 is arranged so as to be inclined by 25 ° with respect to the horizontal so as to match the deflection of the sheet bundle P at the stapling position. The inclination of the stapler 601 is desirably within 10 ° from the inclination of the bin 350. If the angle is larger than that, the stapler 601 cannot cope with the deflection of the sheet bundle and often shifts.

Referring back to FIGS. 3 and 4, the structure of the moving mechanism W will be described. A slide shaft 642 for moving the chuck C is fixed to the chuck bracket 641, and the slide shaft 642 is provided on the slide bracket 643. The bearing 645 is attached together with a stopper so as to fit. The slide bracket 643 uses the groove 646 formed in the chuck bracket 641 as a guide so that the slide bracket 643 does not rotate around the slide shaft 642, and a roller 64 is formed on a shaft 647 formed in the slide bracket 643.
8 is attached. That is, the roller 648
Are inserted into grooves 646 formed in the chuck bracket 641 to prevent the slide bracket 643 from rotating.

The chuck C is moved horizontally by a chuck motor 656 attached to a chuck bracket 641 and a pulley 657 fixed to the shaft of the chuck motor 656.
A pulley 659 rotatably attached to a shaft 658 formed on the chuck bracket 641;
7, 659, and a mounting plate 661 for attaching the timing belt 660 to the slide bracket 643. Therefore, when the chuck motor 656 rotates, the timing belt 660 reciprocates in the horizontal direction, and the slide bracket 643 reciprocates in the horizontal direction. Note that the chuck motor 656 is configured by a stepping motor, and its moving distance and moving speed are controlled by the CPU 900.

A chuck home sensor 662 composed of a photo interrupter is attached to the chuck bracket 641. The chuck home sensor 662 detects the detection bracket 663 to which the slide bracket 643 is attached.
Forty-three home positions a are detected.

In the staple mode, first, the chuck solenoid 635 is off and the upper chuck lever 6 is turned off.
31 and the lower chuck lever 630 are open, and when the chuck motor 656 rotates, the upper chuck lever 631 and the lower chuck lever 630 rotate at a speed described later.
To the chuck position b (FIG. 4) in the direction of. And
When the chuck solenoid 635 is turned on, the lever 63
3 rotates counterclockwise around the shaft 651, and the spring 634 attached to the lever 633 rotates the upper chuck lever 631 around the shaft 652 in the clockwise direction in FIG.

The upper chuck lever 631 and the lower chuck lever 630 are provided with rollers 653a, 65
3b, the lower chuck lever 630 rotates around the shaft 654 in the counterclockwise direction in FIG. 4 in response to the movement of the upper chuck lever 631, and holds the sheet bundle P. here,
The movement amount of the upper chuck lever 631 and the lower chuck lever 630 is determined by the rotation center of the levers 631, 630, the point of force, and the point of action. In the present embodiment, the relationship between the distance between the point of action of the upper chuck lever 631 and the rotation fulcrum and the distance between the force point and the distance between the rotation fulcrum is set to approximately 3: 1, and the distance between the point of action of the lower chuck lever 630 and the rotation fulcrum. , And the relationship between the distance between the force point and the rotation fulcrum is set to approximately 1: 1, and the relationship between the movement amounts of the upper chuck lever 631 and the lower chuck lever 630 is set to approximately 3: 1.

The chucking force is determined by a spring 634 connecting the lever 633 and the upper chuck lever 631. The spring 634 is the upper chuck lever 631
The chuck force increases as the number of sheets P, that is, the thickness, of the sheet bundle P gripped by the lower chuck lever 630 increases, thereby preventing the sheet bundle P from being disturbed due to insufficient chuck force.

When the chuck motor 656 rotates in the reverse direction, the upper chuck lever 631 and the lower chuck lever 630 move to the staple position e at a speed described later, and the side ends of the sheet bundle P are bound by the staple 601 as shown in FIG. . Here, as shown in FIG.
A chuck paper presence / absence sensor 670 composed of an actuator and a photo interrupter is attached to 41, and the sheet bundle P presses the chuck paper presence / absence sensor 670 so that the CPU 900 detects the sheet bundle P. That is,
For example, when the user removes the sheet bundle P on the bin 350, the CPU 900 does not operate the staple 601 to prevent idle hit.

When the stapling operation is completed, the chuck motor 656 rotates forward, the chuck C moves in the direction of the bin 350, and returns the sheet bundle P to the return position c. Then, the chuck solenoid 635 is turned off and the upper chuck lever 6 is turned off.
31 and the lower chuck lever 630 are opened to release the sheet bundle P at the return position c on the bin 350. In this case, the upper chuck lever 631 and the lower chuck lever 630 are
6, the opening amount is limited by a stopper 664.

Next, the chuck motor 656 starts reverse rotation, and the chuck C starts moving in the direction of the home position a. Then, the CPU 900 counts the number of drive pulses of the chuck motor 656, and when performing the stapling operation on the next bin 350, when the chuck C reaches the vertically movable position d, moves the staple unit 600 in the vertical direction. The driving of the staple up / down motor (not shown) is started. That is, the chuck C returns from the vertically movable position d to the home position a, moves to the next bin 350, and stops when it reaches the home position a. And C
The PU 900 initializes the counter each time the chuck C returns to the home position a, and prevents the accumulated error of the counter.

Next, the schematic operation of the above embodiment will be described with reference to FIG. First, an operation mode signal (interrupt tray ejection signal) from the copier is received (step 6-).
1) Receiving the paper size data (step 6-)
2) When the sorter start signal (motor-on signal) is received (step 6-3), the operation mode and size data are determined by the motor-on signal, and the interrupt mode in step 6-4 and below or the sort stack in step 6-7 and below are determined. Transition to mode. Note that the sort / stack mode is started when a motor-on signal is received from the copying machine when the mode is not the interrupt mode.

In the interruption mode, it is checked whether or not the interruption tray is at the interruption position of the sheet transport path (step 6-5). If not, the interruption tray is moved to the interruption position (step 6). −
6). In this interrupt mode, the post-processing device only discharges the paper onto the interrupt tray, and ignores the size data, the discharge destination bin data, and the discharge signal from the copying machine.

In the sort / stack mode, first, it is checked whether or not the interrupt tray is located at a sheet receiving position which does not interrupt the transport path to the bin 350 (step 6).
7) If not at the paper receiving position, the interrupt tray is moved to the paper receiving position (step 6-8). Then
The main motor is turned on (step 6-9), and it is checked whether the size data is determined and the paper size can be jogged (step 6-10). If jogging is possible, the side fence shaft 401 is moved according to the sheet size (step 6-11).

Then, the size data from the copying machine is received again (step 6-12), the bin data of the discharge destination is received (step 6-13), and the paper discharge signal is received (step 6-14). Paper is carried in from the copier. Here, when the copying machine discharges the paper centered, a slanted portion is provided between the copying machine and the post-processing device to slant the paper and align it with the side edge. The pressure release solenoid for driving is turned on and off (step 6-25).

Next, when a stapling start signal is received (step 6-15), stapling is performed during sorting (step 6-16). Then, the deflection solenoid is turned on so that the sheet is guided on the bin 350 corresponding to the bin data of the discharge destination (step 6-17), and when it is detected that the sheet is discharged to the bin 350 (step 6). -18) Then, the above-described ejection end bin data is transmitted to the copying machine (step 6-19), and the deflection solenoid is turned off (step 6-20).

Next, when the size of the sheet discharged onto the bin 350 is jogable (step 6-21), the jog unit 500 is driven to align the width direction of the sheet (step 6-22). If no sort end signal is received from the copying machine, the process proceeds to step 6-23.
Then, the process returns to step 6-12, and the above operation is repeated. When the sort end signal is received, the main motor is turned off (step 6-24), and this process ends. If paper is being conveyed even when the motor-on signal from the copier is turned off, the operation is continued until all the paper is discharged to the bin 350.

Next, the stapling operation will be described with reference to FIG. As shown in FIG. 7A, the instruction data of the start staple bin is received from the copying machine (step 7-).
1) Then, when a staple start signal is received (step 7-2), this staple operation is started regardless of whether the sorting is being performed or after the sorting is completed (step 7-3).

First, it is checked whether or not the staple start bin is the first bin (home position of the staple unit 600) (step 7-4). If it is the first bin, FIGS. As shown in FIG. 2, the chuck motor 656 is rotated so as to advance the chuck C from the home position a to the chuck position b (step 7-7), and then the staple sequence counter is set to "1" (step 7-8). ). If the staple start bin is not the first bin, the staple unit 600 and the chuck unit 602 are lowered to the bin position corresponding to the instruction data of the start staple bin (step 7-5),
Next, the staple sequence counter is set to "5" (step 7-6). Then, the staple sequence counter is checked (step 7-9), and each of the values "1" to "6" is checked, as shown in FIGS.
The control shown in (g) is performed.

If the staple sequence counter is "1", the driving pulse of the chuck motor 656 corresponding to the moving distance of the chuck C is checked (step 7-10) as shown in FIG. b, the chuck motor 656 is stopped (step 7-
11). Then, the chuck C turns on the chuck solenoid 635 for chucking the sheet bundle P (step 7-12), and then the timer is started (step 7-13). Then, it is checked whether the timer value has passed, for example, 150 msec (step 7-14). When the timer value has passed, the staple sequence counter is set to "2" (step 7-15), and the step 7 shown in FIG. −
Return to 9. The timer value is a time for determining whether or not the chuck C has sufficiently chucked the sheet bundle P.
It is not limited to the above timer value.

When the staple sequence counter is "2", the sheet bundle is moved from the chuck position b to the staple position e as shown in FIGS. FIG.
As shown in (c), first, when the jogger unit 600 is located in the same bin as the chuck unit 602, the jogger unit 600 and the chuck unit 602 interfere with each other, so that the jogger unit 600 moves to another bin. (Step 7-16). And
If the jogger unit 600 is not located in the same bin as the chuck unit 602, the chuck motor 656 starts reverse rotation so that the chuck C moves to the staple position e (step 7-17), and the predetermined number of drive pulses is reduced. When output (step 7-18), the chuck motor 65
6 is stopped (step 7-19).

Next, the paper presence / absence sensor 670 for detecting the sheet bundle P is checked (step 7-20). If a sheet bundle is detected, the process proceeds to step 7-21. Jump to 25. In step 7-21, the staple unit 600 turns on a staple motor for binding the sheet bundle,
When the staple motor returns to the home position (Step 7-
22) The stapling motor is turned off to bind the sheet bundle (step 7-23). Then, a staple count signal indicating that the staple operation has been completed once is transmitted to the copying machine (step 7-24), and then the staple sequence counter is set to "3" (step 7-25), and FIG. Return to step 7-9 shown in a).

When the staple sequence counter is "3", the sheet bundle P is returned from the staple position e to the paper return position c as shown in FIGS. As shown in FIG. 7D, first, the chuck motor 656 is rotated so that the chuck C moves forward (step 7-26), and the number of drive pulses corresponding to the distance to the paper return position c is output (FIG. 7D). (Step 7-27), Stop the chuck motor 656 (Step 7-28). Then, the chuck solenoid 635 is turned off (step 7-29), a timer is started (step 7-30), and the timer value is set to 1 for example.
When 00 msec has elapsed (step 7-31), the chuck C
Is started (step 7-32). Next, the staple sequence counter is set to "4" (step 7-33), and the process returns to step 7-9 shown in FIG.

The timer value is also a time for determining whether or not the sheet bundle P is sufficiently separated from the chuck C, and is not limited to the timer value. Further, as shown in FIG. 2, the paper return position c is shifted to the near side by about 10 mm from the paper chuck position b, but any distance may be used as long as the vertical movement of the jogger unit 500 or the staple unit 600 is not hindered. The post-processing time can be shortened by returning the chuck position to the front side from the chuck position b.

When the staple sequence counter is "4", the chuck C is retreating, but the processing differs depending on whether or not all the sheet bundles P have been stapled, as shown in FIG. (Step 7-34). First, when the unprocessed sheet bundle P remains, the chuck C returns to the vertically movable position d shown in FIG. 2 (step 7-).
35), lowering to the next bin is started by driving a motor that moves the staple unit 600 and the chuck unit 602 up and down (step 7-3).
6). Then, when the chuck C returns to the home position a (step 7-37), the chuck motor 656 is stopped (step 7-38). Next, the staple sequence counter is set to "5" (step 7-39), and the process returns to step 7-9 shown in FIG.

When all the sheet bundles P have been stapled, the chuck motor 656 is stopped at the number of drive pulses when the chuck C is retracted to the home position a (steps 7-40, 7-41). Next, the staple sequence counter is set to "6" (step 7-4).
2), and return to step 7-9 shown in FIG. In addition,
As shown in FIG. 2, the vertically movable position d of the chuck C
Is shifted 15 mm closer to the front side than the paper return position c,
Any distance may be used as long as the vertical movement of the chuck C is not hindered, and the processing speed can be increased by starting the vertical movement of the staple unit 600 and the chuck unit 602 before returning to the home position a.

When the staple sequence counter is "5", the staple unit 600 is descending. First, as shown in FIG.
It is checked whether or not the staple unit 600 has been lowered to the advanceable position which is not hindered by the step (Step 7).
-43) If YES, the chuck C is advanced in the direction of the sheet bundle P (step 7-44). That is, the chuck C can quickly chuck the sheet bundle P by considering the vertical position of the staple unit 600, the advance speed of the chuck C when descending, and the position of the end face of the sheet bundle P. When the staple unit 600 reaches the position of the next bin (step 7-45), the staple unit 600 is stopped (step 7-46), and the staple sequence counter is set to "1" (step 7-45). 47), Step 7 shown in FIG.
Return to -9.

When the staple sequence counter is "6", as shown in FIG. 7E, the staple processing of all the sheet bundles P has been completed. In FIG. 7 (g), a mode cycle end signal indicating this is transmitted to the copying machine (step 7-48).
00 to the home position (steps 7-49, 50, 5)
1). Then, the staple sequence counter is cleared (Step 7-52), and Step 7 shown in FIG.
Return to -9.

Step S1 in which the chuck C moves from the home position a to the chuck position b, step S2 in which the chuck C moves from the chuck position b to the staple position e, step S3 in which the chuck C moves from the staple position e to the return position c, and from the return position c Step S of returning to the home position a via the vertically movable position d
4 will be described with reference to FIG.

In the step S1 of moving from the home position a to the chuck position b, the accuracy with which the chuck C stops at the chuck position b affects the positional accuracy of the sheet bundle P at the staple position e. Control is performed so that the speed gradually decreases as the distance approaches b. Accordingly, it is possible to prevent the displacement at the staple position e due to the inertia due to the mass of the sheet bundle P.

In the step S2 of moving from the chuck position b to the staple position e, the movement is started at a high speed without abruptly starting or stopping the movement so that the chucked sheet bundle P does not shift. .

In the step S3 of moving from the staple position e to the return position c, the sheet bundle P has already been stapled, and even if the movement is suddenly started, there is no deviation, so the movement is suddenly started. In addition, since the stop position may be overshot, it is driven to move at the highest speed and stop suddenly. Finally, since it is required to return quickly from the return position c to the home position a via the vertically movable position d, the movement is started at the highest speed and is driven to stop suddenly.

Also, the chuck position b and the staple position e
Since each stop position accuracy affects the needle position accuracy on the sheet bundle P, the needle position on the sheet bundle P can be adjusted. In this case, the adjustment can be made by increasing or decreasing the number of pulses of either one of the steps S1 and S2. However, the moving time is increased by increasing or decreasing the number of pulses at the highest speed in the steps S1 and S2. Can be adjusted without the need.

[0046]

As is clear from the above description, according to the present invention constructed as described above, the deviation of the paper bundle during the post-processing is reduced, so that the shape of the paper bundle after the post-processing is made clear. As well as minimize misalignment of the paper bundle during post-processing.
Can be suppressed .
