Next, the stapler 700 will be described. FIG. 6 is a perspective view of the stapler apparatus 700, showing the bins 350 for stacking copy paper provided in multiple stages.
A stapler device 700 is disposed on the side of the stapler device 700. In this stapler device 700, the stapler 701
And a sheet pulling device (chucking unit) 615,
It is attached to the upper part of the plate-shaped bracket 703 and is fixed respectively. The stapler 701 drives a stapler into each of the finished copy paper bundles stacked on each of the bins (not shown), and the paper drawing device 615 grips the copy paper bundles on each of the bins. , Which are transported almost horizontally. Drive motor 72
The drive belt 717 is transported and driven by the drive force transmission mechanism 0, and thereby the stapler 701 and the sheet pulling device 615 are vertically moved.

FIG. 7 is an explanatory view for making the movement of the stapler apparatus 700 easy to understand. The movement of the copy paper P discharged onto the bin 350, the movement of the chuck section 620, and the position of the stapler 701 will be described. The copy paper P discharged onto the bin 350 is discharged to a position indicated by 730d. Then, bin fluence 4 is performed by the paper alignment device described above.
It is provided at a position where it abuts on 60. Thereafter, when the stapling operation is started, the check section 620 moves from the position 620b indicated by the dashed line to the position 620c indicated by the other dashed line,
The check section 620 is closed to sandwich the copy paper P, and stops at the position 620a indicated by the solid line. By this operation, the copy paper P moves to the position of 730f, and a certain number of copy papers P are stapled on the bin 350 by the stapler 701. Thereafter, the reverse operation is performed, and the copy paper P is 730
It is returned to the position of d. This completes the work for one bin 350, goes to the next bin 350, and repeats this operation.

FIG. 8 is a front view of the sheet pulling device 615, and includes a check section 620 for gripping the copy sheet bundle P on the bin 350, and a reciprocating mechanism 640 for reciprocating the check section 620 substantially horizontally. And In the check section 620, a pair of swing lever upper 622 and swing lever lower 624 are swingably attached to the substrate 621, and the swing lever upper 622 and swing lever lower 624 are connected to a solenoid 626. , The upper chuck 623 and the lower chuck 625 operate to hold the copy sheet bundle P. Reciprocating mechanism 6
40 is a shaft 64 for sliding the chuck portion on the frame 641.
2 is fixed, a bearing 629 fixed to the substrate 621 is engaged with the shaft 642, and the chuck portion 620 is guided by the shaft 642 to reciprocate. The frame 641 is provided with a timing belt 643 for moving the check section 620 toward and away from the copy sheet bundle P. The check section 620 and the timing belt 643 are fixed by an arm section 621a of the substrate 621. Both ends of the timing belt 643 are wound around pulleys 644 and 645, and one pulley 644 is attached to a stepping motor 646. The pulley 644 rotates by the driving of the stepping motor 646, and the timing belt 643 moves. Timing belt 643
As a result, the check section 620 fixed to the timing belt 643 via the arm section 621a reciprocates. The frame 641 has a position sensor 6
A detection plate 630 is set up on the substrate 621 as a detection target, and the position sensor 650 detects the home position of the check section 620.

In the embodiment having such a configuration,
When the stapling mode is started, first, the stapler 701 and the sheet pulling device 615 move up and down integrally by the drive belt 717 shown in FIG. 6, and as shown in FIG. 615 is transported toward a predetermined bin 350 where the copy paper bundle P on which staples are to be driven is deposited, and the position sensor 72 shown in FIG.
Based on the signal from 7, the bin is stopped at a position close to a predetermined bin 350. At this time, the solenoid 626 is turned off, so that the swinging levers 622 and 624 and the chucks 623 and 625 are in an open state. At the same time as the above operation, the fence motor 462 is turned on and the bin fence 460 is opened. Next, the stepping motor 646 rotates a predetermined amount, moves the timing belt 643, and moves the check section 620 forward toward the copy sheet bundle. By changing the rotation speed of the stepping motor 646, the speed of the check unit 620 at the time of movement is controlled. In the case of this embodiment, the check section 620 grips the aligned copy paper bundle with the check pieces 623 and 625, gradually accelerates at the start when returning to the staple position, and gradually decelerates at the stop, thereby aligning. This prevents used copy paper from fluctuating due to inertia during acceleration and deceleration. In the case of moving at the same distance within the same period of time, since the maximum value of the inertial force is the smallest in the uniform acceleration movement, in the present embodiment, the acceleration / deceleration is performed at the constant acceleration.

When the chucks 623 and 625 move to a position where they can grip the copy sheet bundle, they stop there and at the same time the solenoid 626 is turned on. Solenoid 6
The check 623, 625 is closed by turning on 26, and the edges of the copy sheet bundle are gripped by the check 623, 625. If only one corner of the copy paper is gripped by the check 623 or 625, a moment is applied to the copy paper P due to inertia at the time of drawing the paper, and the copy paper P
Is tilted on the bin 350, and there is a problem that the staple position varies. Therefore, a plurality of portions of the copy paper P are gripped so that the copy paper does not tilt even when a moment due to inertia is applied. Next, the stepping motor 64
As a result of the reverse rotation of 6, the chuck unit 620 returns to the original position while holding the copy paper bundle, whereby the copy paper bundle moves in a substantially horizontal direction and is drawn to the stapler 701 side. When the edge portion of the copy sheet bundle is transported to a position where stapling is possible, it stops there. After that, the stapler 701 performs stapling on the edge portion of the copy sheet bundle. When the stapling operation is completed, the stepping motor 646 rotates forward, the check section 620 moves forward, and the stapled copy paper P is returned onto the bin 350, and then the solenoid 626 is turned off. As a result, the top of the previously closed chuck 62
3 and the lower check 625 are opened. Thereafter, the check portion 62 is rotated again by the reverse rotation of the stepping motor 646.
0 retreats to a predetermined position. After that, stapler 70
1 and the sheet pulling device 615 are transported downward toward the next bin 350, where the same stapling operation as described above is repeatedly performed. When stapling has been performed on all copy paper bundles, the stapler 701 moves up and returns to the highest home position.

FIG. 9 is a perspective view showing the bin fluence 460 of the embodiment. In the figure, the bin fluence 460 is pressed against each bin 350 so that the paper alignment of all the bins 350 is performed by one sheet. The fence 460 is rotatably attached to upper and lower rotation fulcrums 460a and 460b. The rotation fulcrum 460b has a gear 460c, and the gear 460c is meshed with a gear 461.
The gear 461 is driven by a drive motor 462. When aligning the copy paper, the fence 460 aligns the paper with the bin 350 as shown in FIG. When all sorts are completed and stapling is performed, the bin fence 460 is rotated by about 90 °, separated from the bin 350, and the copy paper P can be moved to the stapling position.

A signal from the group is received via an I / O port 806,
The output of O port 803 and CTC 804 causes SSR8
07, various drivers 808, 809, 810, 811,
812, and controls each load described later via a phase signal generation unit 813. An optical fiber (not shown) is connected to the copying machine by a UART 805 via a receiver 814 and a driver 815 to exchange status and instruction signals. Among the signals exchanged with the copier, the signals sent from the copier to the stapler 700 of the sorter include a sorter start signal, a copier discharge signal, a staple start signal, a staple end signal, a system reset signal, and a service. Call reset signal (SC reset),
There are a status request signal, a mode signal, a size signal, a discharge bin instruction signal, and the like. The signals sent from the stapler 700 to the copying machine include a model recognition signal, a tray paper signal,
There are a stackover signal, a binover signal, a cover open signal, a needleless signal, a JAM signal, a staple disable signal, a paper discharge signal, a WAIT signal, a BUSY signal, a mode end signal, a staple count signal, an abnormal signal, and the like.

FIGS. 11 and 12 are flow charts showing the overall operation of this embodiment. First, a mode signal sent from a copying machine is received (step 1-1), and after a copy is started, a size signal is received (step 1-1). Next, a sorter start signal is received (step 1-2). With this reception, the sorter motor (at the time of sorting or stacking) or the proof motor (at the time of proofing or interrupting) is turned on by the mode signal. First, the proof mode (steps 1-4) will be described. The proof motor 117 shown in FIG. 1 is turned on (step 1-
5) After that, the switching SOL is turned on (step 1-6),
Upon receiving the paper discharge signal (step 1-7), the copy paper carried in (step 1-8) from the entrance guide 102 is discharged to the upper proof tray 116. After the copy sheet is discharged (step 1-9), a discharge signal is transmitted to the copying machine (step 1-10) to notify that the copy sheet that has been carried in has been discharged. Thereafter, this operation is repeated until the copy is completed (step 1-11). At this time, the jam detection of the copy paper (not described in the flowchart) is naturally performed. After the copy is completed, the switching SOL and the proof motor 117 are turned off (step 1-12), and the process stands by until the next copy operation.

Next, the sort and stack modes will be described. After turning on the sorter motor 313 in FIG. 1 (step 1-13), it is determined whether swinging is possible or not based on a size signal or the like. If swinging is possible (step 1-14), a position corresponding to the received size signal is determined. To the paper alignment axis 502 in FIG.
Is moved (step 1-15). Next, when the copy paper is discharged from the copying machine, a copy destination bin designation signal and a discharge signal of the discharged copy paper are transmitted from the copying machine (step 1-16). The destination bin 350 is determined by receiving the discharge signal (step 1-1).
7). Next, copy paper is carried in from the copying machine (step 1-18). After the carry-in, the entrance sensor is turned on. At a timing after the entrance sensor is turned on, the deflection solenoid (SOL) determined by the discharge destination bin instruction signal is turned on (step 1-19), and the copy paper is transferred to the bin 350. Lead. When the copy paper is discharged (step 1-20), a paper discharge signal is transmitted to the copying machine (step 1-21), and bin 3 is output.
Inform the copying machine that the paper has been reliably discharged onto the copying machine. Based on this signal, the copying machine determines the next discharge destination and the discharge destination after the recovery of the jam. After an appropriate time elapses until the copy paper is set on the discharged bin 350 and the operation of the copy paper is settled (for example, after 300 ms; Step 1-2)
2), to turn on the size moving motor 515 of FIG. 3, sheet
By moving the alignment shaft 502 (step 1-2)
3) Align the paper in a direction (horizontal) perpendicular to the discharge direction. The timing at which the paper aligning shaft 502 is moved is detected based on the trailing edge of the copy paper detected by the paper discharge sensors 322 and 324 (step 1-24).

The above operation is performed every time a copy is ejected, and sorting is performed. When the sorting is completed in this manner (Step 1-25), the sorter motor 313 is turned off (Step 1-26), and the stapling operation is performed. When the stapling start signal is received (Step 1-27), the stapler 700 is operated (Step 1-28), and stapling of the stacked copy sheets is performed. When the stapling operation is completed (Step 1-29), the stapler 700 and the paper alignment shaft 502 move to the home position (Step 1-30).

FIG. 13 is flowchart for explaining a paper alignment operation, 14 to 18 shall apply an explanatory view showing the operation of the sheet aligning shaft, sheet alignment axis 502 position based on the size signal as described above ( In the present embodiment, a position 10 mm from the end surface on the side of the paper alignment shaft 502 where the copy paper P is discharged.
Has been stopped in advance. Use of copy paper P is this is to be discharged
The position is such that jamming, paper folding, etc. do not occur when hitting the paper alignment shaft 502 (FIG. 14). After an appropriate time has passed since the copy paper P was discharged, paper alignment is performed by the paper alignment operation of the paper alignment shaft 502. The appropriate time is a time until the operation of the copy paper P discharged onto the bin 350 is settled, and can be changed according to the paper size (for example, 3).
00 ms). The paper alignment axis 502 is 1 in the copy paper P direction.
An output is performed from the I / O port 803 so as to move by 5 mm, that is, the number of pulses equivalent to 15 mm in the CCW direction, and the size moving motor 515 is driven by the constant voltage driver 811 to move the paper alignment shaft 502 (step 2).
-1; FIG. 15).

The speed at this time is 500 pps, but may be any speed that does not cause any troubles such as wrinkles, scratches or breaks in the copy paper P. By this operation, the first paper alignment operation of aligning the copy paper P with the bin fluence 460 is performed, and the operation of dropping the bin P using the inclination of the bin 350 is promoted. An appropriate time until the paper falls (can be changed depending on the paper size, for example, 50 m
s) After stopping the paper aligning shaft 502 (Step 2)
2) Further, the paper alignment shaft 502 is moved so as to approach the 10 mm bin fluence 460, and the second paper alignment is performed.
The operation is performed (Step 2-3; FIG. 16). The copy paper P discharged onto the bin 350 by this operation is pressed against the bin fence 460 by 5 mm over feed. This excessive pressing is for achieving a variation in the length of the copy paper P and a reliable alignment.
An appropriate value may be used instead of 5 mm. After pressing the copy paper P, the paper alignment shaft 502 is stopped for a predetermined time (in this embodiment, 50 ms; step 2-4). This is because the copy paper P is settled and the size movement motor 515 is switched between forward and reverse rotations. This is not particularly necessary, and there is no need to wait. Thereafter, the paper alignment shaft 502 is moved away from the 5 mm paper, that is, moved in the CW direction by the number of pulses equivalent to 5 mm (Step 2-5; FIG. 17). The speed at this time is 500 pps, which is slower than the speed of returning due to the over-adjustment of the copy paper P, and a speed that does not disturb the alignment once due to the return of the copy paper P due to the stiffness. Further, by stopping the carriage back by 5 mm, the paper aligning shaft 502 plays the role of the opposite bin fluence when the paper width matches the paper width. Further, by stopping the carriage for 50 ms (Step 2-6), the copy paper P is surely removed. Will be aligned.

The longer the stop time is, the better the alignment accuracy is. Therefore, the paper alignment shaft 502 is stopped until the leading edge of the copy paper P to be discharged next is detected by the paper discharge sensors 322 and 324. Therefore, the stop time varies depending on the size (the maximum is 500 ms in the embodiment). Thereafter, the paper alignment shaft 502 returns to the initial position (step 2-7; FIG. 18) and stops (step 2-8) in preparation for the discharge of the next copy sheet P. The speed at this time may be any speed that is higher than the speed at which the next copy paper P is discharged.
Also, upon operation of FIGS. 14 to 18, sheet alignment axis 502
And the constants of the springs 503a and 503b supporting the same, the paper aligning shaft 502 bounces during the movement and becomes a load in the movement direction, and the size movement motor 515 may lose synchronism. By changing the speed at the time of stop and stop, the bounce of the paper alignment shaft 502 is eliminated and the step out of the size movement motor 515 is prevented. . By the way, after the number of stacks of the copy paper P in the bin 350 exceeds the stapleable number (30 in this embodiment), stapling of the discharged copy paper P is prohibited, and the sorting is prevented. sheet aligning stop operation becomes, and the sheet aligning <br/> shaft 502 is retracted home position Chillon f.

[0024]

As described above, according to the present invention,
The paper alignment member is moved from the first stop position, which is the home position, to a third stop position for bending the paper between the home position and the fence, and a second width from the fence to the stop position is longer than the paper width. Since the stop position, in other words, when the paper aligning member comes into contact with one side of the paper, a position where a gap is provided between the other side surface of the paper and the fence is provided to adjust the posture of the paper, It is possible to prevent the paper from being aligned obliquely or to perform the paper alignment in a state in which the paper is not sufficiently dropped, and to ensure the paper alignment.
