Abstract

PURPOSE:To prevent the deviation of a paper in accordance with the kind and the state of the paper and to improve productivity by varying a paper moving speed based on information on the size of the paper, the number of stacked papers or the thickness of the paper. CONSTITUTION:In the case of moving the bundle of the papers stacked on a bin 350 to a post-processing position, the paper moving speed is controlled to be varied based on the information on the size of the paper, the number of the stacked papers or the thickness of the paper. Namely, in the case that the bundle of the papers is thick and the size of the paper is large, the paper moving speed is made low to prevent the deviation of the paper. In the case that the bundle of the paper is thin and the size of the paper is small, the paper moving speed is made high because there is no fear of the deviation of the paper. Thus, the productivity in the post-processing for paper is kept at a specified level.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a sorting means that sequentially sorts sheets discharged from a copying machine main body and includes a bin for storing them, and a sorting means for aligning the sheets discharged into the bins. a paper moving means for moving the sheets aligned at one end of the bin to a processing position where stapling, punching, etc. are performed; and a processing means for performing stipple, punching, etc. processing on the moved sheets. The present invention relates to a paper post-processing device.

[Conventional technology]

Conventionally, paper stacks are discharged onto a sorter bin, the stacked paper stacks are aligned on one side of the bin, and then the paper stacks are moved to processing positions outside of the bin for stipples, punching, etc., and various types of processing are performed. Various post-processing devices have been proposed.

[Problem to be solved by the invention]

However, with conventional devices, this stack of paper was always moved at the same speed regardless of the paper type and condition (size, thickness, number of sheets loaded, etc.), so if the paper stack was large or the number of sheets loaded There was a problem with shifting when

On the other hand, if the speed is slowed down to avoid misalignment, there is a problem in that in the case of a stack of paper that is small in size and has a small number of stacked sheets, it takes more time to move (processing time) than necessary, which lowers productivity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper post-processing device that can prevent paper misalignment depending on the type and condition of the paper and improve productivity.

[Means to solve the problem]

The above purpose is to provide a sorting means having bins for sequentially sorting and storing sheets ejected from the copying machine main body, an aligning means for aligning the sheets ejected to the bins, and an aligning means for aligning the sheets at one end of the bin. In a paper post-processing device that has a paper moving means for moving the paper to a processing position where stapling, punching, etc. are performed, and a processing means that performs stapling, punching, etc. on the moved paper, the size of the paper and the number of sheets loaded1
This is achieved by providing a control means that varies the paper moving speed based on at least one piece of information such as paper thickness.

[Operation] The control means controls the paper moving speed to be variable based on at least one of information on the size of the paper, the number of bI sheets, or the paper thickness.

In other words, for example, if the paper is thick (thick paper stack) or large size paper, the paper movement speed is slowed down to prevent paper shifting, and if the paper is thin < (paper stack is thin) or small size paper In this case, there is no risk of paper misalignment, so the paper movement speed is increased in order to improve productivity.

FIG. 3 is a front view showing details of the souvenir sending section 100, and FIG. 4 (
al is a side view showing details of the souvenir sending section 100, in which copy paper discharged from the copying machine main body is placed on a guide plate 101.1.
02 and transported to the switching claw 103. This switching pawl 103 is connected to a switching solenoid (SQL) 107 via links 1°4, 105, 106, and when the solenoid 107 is turned off, the copy paper is moved to the diagonal section 200 provided below the souvenir sending section 100. Again, solenoid 1070
When it is turned on, it operates so as to feed each into one conveying section 100.

When the solenoid 107 is turned on, the switching pawl 103 operates, and the copy paper guided into the first conveying section 100 is transferred to the switching pawl 1.
03 is sent to a conveying roller 108 provided at the top of the scoop. The conveying roller 108 is made of EPDM or chloroprene rubber, and is moved by the driven roller 10 under the action of a leaf spring or the like.
9 is pressing, and conveying force is obtained. The conveying devices constituted by a combination of these conveying rollers 108 and driven rollers 109 are arranged in three vertical rows and convey the copy paper upward one by one. In this conveyance device, the copy paper is transferred to the guide plate 10.
1 and the guide plate t10, and is conveyed to the discharge roller 111, and is discharged to the brew tray 116.

The above-mentioned driven roller 109 and switching pawl 103 are attached to the kite plate 110, and as shown in the plan view of the guide plate 110 portion (not shown in FIG.
It is designed to rotate and open around the center. By rotating and opening the guide plate 110, the switching pawl 103 or the driven roller 109 is opened, making it easier to handle paper jams and the like in this area.

Copy paper conveyed by three vertical rows of conveying rollers 10B and driven rollers 109 is guided by guide plates 101, 114 and conveyed to a discharge roller 111. The material of the discharge roller 111 is also made of EPDM or chloroprene rubber like the conveyance roller 108.
The driven roller 115 of No. 1 is also the driven roller 109 of the conveying roller 108.
Similarly, it is pressed by a plate spring or the like and has a discharging force.

The copy paper that has been conveyed to the ejection roller 111 is ejected to the brochure tray section 116 shown in FIG. 1 by the action of the ejection roller 111 and the driven roller 115. As shown in FIG. 1, the bruft tray section 116 is located closer to the main body than the sorting bin 350. This means that the copy paper can be moved closer to the operator, which improves operability by making it easier for the operator to see and take out the copy paper, and also shortens the transport distance of the copy paper, reducing the time it takes to eject the copy paper. It has also been shortened. Further, since this proof tray portion 116 also serves as a part of the upper cover, which is an exterior body, there is no need to provide a dedicated proof tray.

FIG. 5 is an explanatory diagram showing the drive system of the souvenir sending section 100, and the souvenir sending section 100 is independently provided with a motor 117.
The driving force is transmitted by the timing belt 118 via gears 130 and 131 to timing pulleys 119 and 120 fixed to the shafts of the conveyance roller 108 and the discharge roller 111, respectively, and drives the conveyance roller 108 and the discharge roller 111. This is a configuration where there is

Further, a feature of the souvenir sending section 100 described above is that no conveying rollers are provided between the main body discharging section and the switching claw 103. This means that when the brochure tray section 116 is in use mode, the copy paper is conveyed by simply operating the drive motor 117 of the souvenir sending section 100 and the solenoid 107, and when the bin 350 is being used, the drive motor 117 of the souvenir sending section 100 is operated. , and the solenoid 107 are configured so that they do not need to be supplied with power, and are configured to efficiently supply power.

This souvenir sending section 100 is unitized and can be easily attached and detached. For example, as shown in the front view of another embodiment of the souvenir sending section 100 shown in FIG. Even if the ejection position of the copying machine body is different due to installation, this post-processing device can be used by simply replacing the unit U.

In FIG. 6, common members with those in FIG. 1 are given common symbols.

Next, the diagonal portion 200 in FIG. 1 will be explained in more detail.

The diagonal part 200 is a unit for changing the center reference of the copy paper discharged from the copying machine main body to the front end face reference in the conveyance path, and as shown in FIG. It is located in the vertical part below 103. The purpose of using the vertical conveyance path in this way is to downsize the entire apparatus and save space.

Copy paper discharged from the copying machine is guided by the switching claw 103 when the bin 350 is in use mode, such as sorting or stacking, and is sent to the lower diagonal receiving roller 201. The diagonal receiving roller 201 is made of EPDM or chloroprene rubber, and a driven roller 214 is pressed by a temporary spring or the like to obtain a conveying force.

FIG. 7 is a side view of the diagonal roller 202 portion, and shows that the copy paper is conveyed toward the reference guide 204 by approximately 25 mm.
Two diagonal rollers 202 are disposed with an inclination of ~30''. Similar to the diagonal section receiving rollers 201, these diagonal rollers 202 are also made of EPDM or chloroprene rubber.

A ball 215 pressurized by a compression spring 218 is used as a driven roller as shown in the enlarged sectional view shown in FIG. This prevents buckling, etc. The copy paper is conveyed diagonally to the reference guide 204 by the diagonal rollers 202 and then sent to the diagonal discharge roller 203. The diagonal discharge rollers 203 ensure the conveyance to the blowing path, and are made of the same material as the diagonal receiving rollers 201.

In FIG. 8, the driven case 219 and the holding member 2 are shown.
20 and a compression spring 21B, the driven ball 215 in the vertical conveyance path is pressurized.

The speed V in the conveying direction of the conveying roller is determined by the diagonal receiving roller 20.
The speed of 1 # 1 # The speed of the diagonal roller 202 v2 x the speed of the diagonal section discharge roller 203 ■. However, since the velocity v2 of the diagonal roller 202 has a component in the downward conveying direction, V 2 = V 2
m x CO3θ, and since Via=V2 in the example, V 2 = V 3 Cos θ.

Further, the relationship between the conveying forces F of the respective conveying rollers is as follows: conveying force Ft of the diagonal section receiving roller 201>conveying force F2 of the diagonal roller 202#conveying force F3 of the diagonal section discharging roller 203. The reason why only the conveying force F of the diagonal receiving roller 201 is increased in this way is that even if the leading edge of the copy paper is fed into the diagonal roller 202, the copy paper is kept diagonally until the trailing edge passes through the diagonal receiving roller 201. The purpose is to prevent this and keep the timing of the tilt constant. Furthermore, the reason why the conveyance force F3 of the diagonal discharge roller 203 is made equal to the conveyance force Ft of the diagonal roller 202 is to provide a margin for the diagonal conveyance distance.

Next, a method of driving each conveying roller of the diagonal section 200 will be described.

FIG. 9 is an explanatory diagram showing the drive system of the diagonal section 200. In FIG. 7.9, the driving force input from a timing pulley 210 fixed to the shaft of the diagonal section discharge roller 203 is transmitted to the diagonal section receiving roller 20 through a double-toothed timing belt 213.
The driving force is transmitted to the timing pulley 206 fixed to the shaft 1, and the diagonal portion receiving roller 201 obtains the driving force.

Fig. 10 is an enlarged front view of the drive transmission part, and Fig. 7.1 is an enlarged front view of the drive transmission part.
In Figure 0, since the axis of the diagonal roller 202 needs to be tilted diagonally, the helical gear 209 and the helical gear portion 208
The driving force is obtained from the double-tooth timing belt 213 via the idler 208, which is made up of a timing pulley portion 208b and a timing pulley portion 208b.

FIG. 11 is an explanatory diagram showing the oblique movement of the copy paper, and this figure shows the ideal movement of the copy paper when the copy paper is oriented obliquely.

That is, when the rear end of the copy paper P leaves the diagonal section receiving roller 201, the diagonal direction begins, and when the end surface hits the reference guide 204, the diagonal direction ends, and the copy paper P is straightly conveyed by the diagonal section discharge roller 203. It will be done.

FIG. 12 is a partial cross-sectional view of the reference guide 204,
In this embodiment, the reference guide 204 is fixed to the diagonal portion driving side guide plate 205 opposite to the diagonal portion driven guide plate 217 with a screw fastener.

The copy paper sent out from the diagonal section 200 is transferred to the lower conveyance guide plate 308 and the driven guide plates 309 and 310 in FIG.
and is sent to the deflection section B by conveying rollers 301 and 302 and driven rollers 305 and 306. The deflection section B is composed of a deflection section discharge roller 304, a driven roller 307, a driven guide plate 311, and a deflection claw 312.
12 can be individually operated by solenoids. The deflection claw 312 is opened and closed by a solenoid according to specified mode conditions to guide and stack one sheet of paper into each bin 350.

FIG. 13 is a perspective view schematically showing the rocking device, FIG. 14 is a plan view showing the relationship between the rocking device and the bottles, and FIG. 15 is a side view of the rocking device, showing an example of each bottle 350. A bottle fence 450 is erected on each edge, and a bottle rear end rising portion 508 is erected on the other side edge that is orthogonal to the edge where the bottle fence 450 is provided.

Further, an elongated portion 511 is provided on the edge opposite to the edge on which the bin fence 450 is provided.

As shown in FIG. 14, when the distance a from the bottle rear end rising portion 508 is the distance between the bottle fence 450 and the bottle rear end rising portion 508, the long portion 511
It is provided so as to extend over a predetermined length toward the bin fence 450 between a width C of 50 mm.

In this embodiment, the three dimensions are set between 125 and 140 mm. This is the result of experiment, 3 dimensions are 125mm
In the following case, when copy paper P of large size such as A3 is used, a moment as shown in the top view of the bin in Figure 16 is applied, and it is found that good shifting cannot be achieved. It has been found that if the width is 140 mm or more, a moment as shown in the top view of the bin in Figure 17 will be applied when using small-sized copy paper P such as B5 horizontal, making it impossible to achieve good shifting. Therefore, the three dimensions were set between 125 mm and 140 mm.

Further, in FIGS. 13 to 15, a swing shaft 5.degree. 2 having a round cross section is vertically provided so as to penetrate vertically through each long portion 511 provided in each bottle 350.

This swing shaft 502 is for aligning the position by coming into contact with the end face of the paper bundle, and the surface of the swing shaft 502 is made of a high-friction rubber member.

Sponge, sandpaper, sandblasting and adhesive treatments are applied. In addition, as shown in FIG. 15, the swing shaft 502 is designed to prevent excessive force from being applied to the stack of copy paper due to the elasticity of leaf springs 503a and 503b, which may damage or wrinkle the copy paper or overload the motor. It has become.

FIG. 18 is an explanatory diagram showing the action of the copy paper and the swing shaft 502. When the copy paper curls upward, the swing shaft 502
Even if you try to align it with 02, it will just slip and try to go up like the situation from ■ to ■ in the explanatory diagram of FIG. The friction member suppresses the slippage of the copy paper, ensures that the copy paper reaches the bin fence 450, and ensures good alignment.

Further, the upper end and the lower end of the swing shaft 502 are connected to the first
As shown in FIGS. 3 and 15, a timing belt 507a is inserted into the recesses of the holders 504a and 504b, and extends in the upper and lower regions of the bin 350 in substantially the same direction as the elongated portion 511. and 507b are respectively arranged. Then, the holder 504
2. The convex part of 504b enters and is fixed.

Of the pulleys 509, 510, and 512 on which the timing belts 507a and 507b are respectively hung, the pulleys 509 and 512 are respectively fixed to both ends of a drive shaft 514 that is provided to extend in the vertical direction. There is. The lower timing belt 507b is hung around a pulley 512 provided on the output shaft of the size movement motor 515.

Movement according to the size of the swing shaft 502 is performed by the size movement motor 5.
It is managed by the number of pulses given to 15.

For a certain paper size, the swing shaft 502 is stopped at a certain distance from the ejected copy paper by the size movement motor 515 (10 mm in this embodiment). At the same time when the ejection is completed and the copy paper falls to the rear edge rising part 508 of the bin, the swing shaft 502 is moved toward the copy desk side and the copy paper is bitten by a certain amount (5 mm in this embodiment) from the surface of the copy paper Ifi.
) is managed by pulses to have a

When the swing shaft 502 finishes pressing the copy paper and returns, it stops at the width of the - copy paper size and then returns to the normal position, or the speed at which the swing shaft 502 moves can be varied to ensure that the copies are aligned once. The paper is prevented from being separated from the bin fence 450 again due to its stiffness.

The copy paper stack is pressed against the bin fence 450 side by the swing shaft 502, and as a result, one side end surface of the copy paper stack is aligned. A method is used in which the copy paper is brought against the upright portion 508 of the bin, which is orthogonal to the alignment bin fence 450 on the other side end surface, and the copy paper is dropped by utilizing the slope of the bin 350 as one means of alignment. .

The bin 350 has been designed in various ways to facilitate paper alignment and stipple.

FIG. 19 is an explanatory diagram showing the state when the bin 350 is installed, and shows the bin main angle part 401 and the bin semi-angle part 402.
, 403 are moderate.

When the bin main angle portion 401 is set to a certain predetermined angle (30° in this embodiment), as the ejected copy paper is stacked, the copy paper gradually begins to buckle. This is noticeable on thin paper [see the copy paper buckling state (portion A) shown in FIG. 20]. Bin semi-angle part 403
The buckling of the copy paper described above can be prevented by supporting the weight of the copy paper to some extent at the bin semi-angular portion 403. In this embodiment, the angle of the bin semi-angular part 403 is 15''. However, if the length of the bin main angle part 401 is short and the length of the bin semi-angular part 403 is long, the copy will be made at the bin semi-angular part 402. There are cases where the weight of the paper is supported too much and the copy paper does not fall.Therefore, the bin main angle section 4
01 and the bottle semi-angular part 403 need to be appropriate lengths, preferably about 300 mm for the main bin angle part and about 80 mm for the bin semi-angular part.

Further, the bin semi-angular portion 402 is provided as a countermeasure against face curl. A stack situation of copy paper exhibiting face curl when the bin semi-angle section 402 is not shown in FIG. 21, and a stack situation of copy paper exhibiting face curl when the bin semi-angle section 402 is shown in FIG. 22. A comparison between the 0 section in FIG. 21 and the d section in FIG. 22 is shown. Copy 0 in Figure 21 indicates that the copy paper stack P is in bin 3.
However, in copy 0 in FIG. 22, the stack of copy sheets P is not far away from the top of the bin 350. This indicates that the shape shown in FIG. 22 allows a larger number of sheets to be stacked with respect to the stack of copy sheets P exhibiting face curl than the shape shown in FIG. 21. In this embodiment, the bin semi-angular portion 402 has a diameter of 15'' and a length of approximately 20 mm.

FIG. 23 is a front view showing the entire bin 350, and FIG. 24 is a plan view of the bin 350. A convex portion 411 protruding from the bottom of the bin 350 is used to suppress curling of copy paper. Copy paper discharged onto the bin 350 is aligned in one direction, but copy paper with large curls may climb over the bin fence 450 provided on the side of the bin 350, making alignment difficult. The convex portion 411 is installed to prevent copy paper from curling, etc., and to enable good alignment.

FIG. 25 is a partial sectional view of a bottle 350 with a curling press, and FIG. 26 is a partial sectional view of a bottle 350 without a curling press. It shows step by step the state over time when the paper is aligned.

In FIG. 24, 412, 413, and 414 are handles for fixing the bottle.

FIG. 27 is a side view of the bottle 350, showing the installed state. In the figure, 430a and 430b indicate side plates;
31a and 431b indicate bottle holder stands. Vinfence F
The bottle holder on one side fixes the bottle 350 on a stand 431a, and the bottle holder on the other side only supports the bottle 350 with a slight gap between the stand 431b and the bottle 350. By fixing the bin fence F side, the stipple position can be prevented from varying. Further, the small gap provided in the bottle holder on the side of the stand 43Ib allows thermal expansion of the bottle 350 to be absorbed.

In FIG. 24, reference numeral 511 is an elongated hole through which the swing shaft 502 moves in accordance with the paper size. Bin rib 415a
is provided to improve the falling property of copy paper. When the copy paper is loaded on the bin 350, the bin 350
To prevent bending, bottle ribs 415b, 415c,
The portion of 415e near the notch for taking out the copy paper is higher than the other ribs. When the copy paper is bent, the falling property of the copy paper is significantly deteriorated. Further, when the copy paper is swung by the swiveling shaft 502 shown in FIG. 13, the alignment accuracy may not be achieved even if the sagging copy paper is swung because it has no stiffness. The rib 415f of the bin 350 is designed to prevent the ejected copy paper from slipping into the long part 511 for the swing shaft.

Figure 28 shows a groove 415f near the long part 511 for the swing shaft.
The ribs 415f protrude above and below the bin 350 to prevent copy sheets to be stacked from going under and at the same time from entering the notch of the upper bin.

The arrangement of the ribs 415f is also 1 from the edge of the copy paper size.
It is set near 0mm, especially the long part 41.
Consideration has been given to ensuring that the edge surface of the paper, which tends to become zero, is guided reliably.

In addition, the shape of the rib 415f on the upper side of the bin 350 in FIG. 28 forms a gentle triangular shape on one side because it is ejected when the chucked copy paper stack P is stippled (described later) and then ejected. The copy paper is ribbed 415
This is to guide the guide so that it does not get caught in f. In the vicinity of the rising portion 508 of the rear end of the bottle in FIG. 23, the ribs 415'' are both low ribs 415f and 415h, as shown in FIG. 29, and gradually become higher up to the longer portion 511. This is done to ensure a large number of sheets can be loaded.Also, the rib position of the bottle rib 415g in Fig. 24 follows the rib 415f.This rib is provided to improve the falling of copy paper. There is.

The cutout 416 shown in FIG. 24 is a cutout for the chucking unit to chuck the copy sheets arranged on the bin 350.

The portion 417 in FIG. 24 is depressed below the other surface of the bottle 350, as shown in the side view of a portion of the bottle 350 in FIG. 30. This section 417 is provided for taking out small size paper. If the notch 422 for taking out the copy paper is made deeper, the portion 417 becomes unnecessary, but in that case, the strength of the bin 350 will be extremely deteriorated.

The portion 417 serves to maintain the bin strength and to make it easier to take out the copy paper when taking out the small size paper. Further, 418 in FIG. 24 is a notch for the paper discharge roller.

Figure 31 shows the discharge roller 304 and the rising portion 508 at the rear end of the bin.
FIG. 2 is an explanatory diagram showing the positional relationship between the ao and the ao, in which ao has an angle slightly larger than 90°. The b part is a straight part, and the 0 part is a curved part. The ejection roller 304 is not located on the same plane as the 0th copy, but protrudes further in the paper ejection direction than the 0th copy. The shape of the bottle rear end rising portion 508 shown in FIG. 31 is effective in terms of alignment accuracy in face curling. However, as the number of stacked sheets increases due to face curl, the stack of copy sheets P is stacked higher than the bin upright portion 420, resulting in "trailing edge rising X" as shown in FIG. 32. In this embodiment, by combining the shape of the rising portion 508 at the rear end of the bottle, which is effective against face curl, and the protrusion of the discharge roller 304 into the bin 350, it is possible to improve the alignment accuracy of the face curl, and to prevent the protrusion from occurring. By scraping off the copy paper with the discharge roller 304, problems such as the above-mentioned "back end rolling up" X are prevented.

419 in FIG. 23 and 421 in FIG. 24 are ribs provided to reinforce the bottle. Furthermore, alignment by dropping may not provide sufficient alignment accuracy depending on the type of copy paper. To compensate for this, a collapsing roller device 550 is provided.

FIG. 33 is a front view of the shifting roller device 550, and FIG. 34 is a plan view of the deflecting roller device 550.
A shifting roller 333 is attached to a driven shaft 332 held by a shifting roller holder 331 attached to a shaft 340 of 04. In addition, a drive pulley 334 is fixed to the deflection section discharge roller 304, a driven pulley 334 is fixed to the driven shaft 332, and a driven boot 17335 is fixed to the driven shaft 332.
The moving roller 333 is driven in conjunction with the round bell) 336. Driving boo 'J 334 and driven boo + J 335
has an inclination of 106, and the shifting roller 333 moves the copy paper diagonally to the bin fence 450.
It is possible to align both sides of the rear end rising portion 508 of the bottle.

FIG. 35 is an explanatory diagram showing the relationship between the copy paper P and the shifting roller 333, and shows the relationship between the deflection section ejection roller 304 and the driven roller 3.
The copy paper P conveyed by 07 is discharged into a designated bin 350 by opening the deflection claw 312. At this time, the shifting roller 333 is 5 to 7 mm away from the bin 350, and the copy paper P is discharged above the shifting roller 333 (state of ■). The rear end of the copy paper P is 20 to 30 mm from the rising portion 508 of the rear end of the bin depending on the speed at which it is ejected.
It pops out mm. The center of the shifting roller 333 is 15 mmg1 from the rising portion 508 of the rear end of the bottle, and
Copy paper P that is 20 mm away from zero and has fallen onto the shifting roller 333 is scraped onto the bin 350 by the shifting roller 333. The copy paper P that has fallen into the bin 350 is guided by the inclination of the bin 350 to the rear end rising portion 508 of the bin, and slips into the lower part of the shifting roller 333 (state of ■).

Thereafter, the swing shaft 502 is moved as described above at the timing when the rear end of the copy paper P contacts the bin rear end rising portion 508, and the copy paper P is brought into contact with the bin fence 450 to align the copy paper P. Thereafter, as shown in the front view of FIG. 36 showing the installed state of the collapsing roller device 550, by pulling the solenoid 342, the bracket 337 is pulled upward, and the bin 339 inserted into the hole 338 of FIG. 33 is raised. , the shifting roller holder 331 rotates counterclockwise around the shaft 340, and the shifting roller 333 falls onto the bottle 350. Then, by rotation of the shifting roller 333, the copy sheets are brought into alignment against the bin rear end rising portion 508 and the bin fence 450. The operating times of these swinging rollers and the shifting roller 333 are set so that they end before the next copy sheet is ejected or before it enters between the shifting roller 333 and the bin 350. The next copy paper is then aligned in the same way.

The copy paper is moved to the bin fence 45 by the shifting roller 333.
0 and the rear edge rising portion 508 of the bin. However, if the force to pull the copy paper is too strong, the copy paper P will buckle as shown in FIG. It is designed so that it can transport one sheet of paper, and it will slip after it hits a collision. For this reason, as shown in FIG. 38, a high friction member 333b is provided on a part of the low friction member 333a of the shifting roller 333 so as to protrude beyond the circumference of the shifting roller 333. In addition, as shown in the front view of the collapsing roller 333 in Fig. 39.40, a plurality of high friction members 33
3b may be provided.Furthermore, by providing an appropriate friction member on the bringing rollers 333 and setting the roller pressure, the same effect as described above can be obtained.

The stack of copy sheets aligned as described above is taken out in the direction of arrow X in FIG. 14 after various post-processing operations such as stapling operation, which will be described later, are executed. Since there is nothing in this take-out direction that would impede take-out, the copy paper take-out operation is easily performed.

Next, the stapler device F700 will be explained.

FIG. 41 is a perspective view of the stapler device 700, FIG. 42 is a plan view of the stave bluff placement, and FIG. 43 is a front view of the bearing portion, showing a side view of the bin 350 for stacking copy paper provided in multiple stages. A stapler device 700 is disposed at. In this stapler device 700, the stapler bluff 01 and the paper pulling device 615 are attached to the upper part of a plate-shaped bracket 703 and are each fixed thereto. The stay bluff 01 is used to drive stipples into each of the later copy sheets stacked on each bin (not shown), and the paper pulling device 615 grips the copy sheets stack on each bin. do,
It is meant to be transported almost horizontally. The bracket 70
A bracket 703 is attached to the part where one end of 3 is bent upward.
a is attached to the bracket 703a, and the 42nd,
The bearing 704 shown in FIG. 43 is fitted, and the retaining ring 7 shown in FIG.
It is fixed at 05. Holders 708 and 7 with bearings 704 attached to base 706 and top plate 707 in FIG.
09 through the slide shaft 710. Rollers 714 and 715 are provided on shafts 712 and 713 provided on bracket 711, and bracket 716 is sandwiched between rollers 714 and 715.

Furthermore, a drive belt 717 is provided upright along the side of the bin 350 and substantially parallel to it. This drive belt 717 is inserted between the bracket 703a and the mounting plate 718 and fixed with screws.

The drive belt 717 is passed between pulleys 719a and 719b which are vertically spaced apart from each other by a predetermined distance. Then, the boot +7
723 and a drive gear 724 fixed coaxially,
The drive pulley 7 is fixed to one end of a support shaft 726 through a gear 725 meshed with the drive gear 724.
Rotational driving force is transmitted to 19a. The drive belt 717 is conveyed by such a driving force transmission mechanism, and thereby the stay bluff 01 and the paper pulling device 615 are conveyed in the vertical direction.

Furthermore, a position sensor 7 is provided on the bracket 711.
27 is attached, and the position sensor 727 is provided to sandwich the bracket 716. Holes 716a for indicating positions are formed in the bracket 716 at predetermined intervals so as to correspond to the positions of the respective bins. With such a position detection mechanism, the stay bluff 0
1 and the paper pulling device 615 are controlled to be stopped at the installation position of each bin.

The protrusion 728 and sensor 729 in FIG. 41 are for determining the upper limit position of the bracket 703, and when the protrusion 728 enters the sensor 729, the motor 720 stops raising it.

FIG. 44 is an explanatory diagram for making it easier to understand the movement of the stay bluff 01, and describes the movement of the copy paper P discharged onto the bin 350, the movement of the chuck unit 731, and the position of the stay bluff 01.

The copy paper P discharged onto the bin 350 is discharged to a position as shown by 730d. Thereafter, it is placed in a position where it comes into contact with the bin fence 450 using the swinging device described above.

Then, when the copy is finished and the stipple starts,
The chuck section 620 moves from a position 620b indicated by a dashed dot line to another position 620c indicated by a dashed dot line, closes the chuck section 620 to sandwich the copy paper P, and stops at a position 620a indicated by a solid line. This operation moves the copy paper P to the position 730f, and a certain number of copy papers P are stippled on the bin 350 by the stay bluff 01.

Thereafter, the previous operation is reversed, and the copy paper P is returned to the position 730d. This completes the work for one bin 350, moves on to the next bin 350, and repeats the operation. The details of their operation will be explained later.

FIG. 45 is a front view of the paper pulling device 615, FIG.
47 and 48 are front views of the paper pulling device 615 in an operating state, showing a chuck section 620 that grips the stack of copy sheets P on the bin 350 and a reciprocating movement of this chuck section 620 in a substantially horizontal direction. A reciprocating mechanism 640 is provided to allow the reciprocating movement. In the chuck part 620, a pair of swinging levers 622 and 624 are connected to the substrate 621.
is attached so that it can swing freely, and this swing lever upper 6
22 and the lower swing lever 624 are operated by the solenoid 626, so that the upper chuck 623 and the lower chuck 625 are operated to grip the stack of copy sheets P.

In the reciprocating mechanism 640, a shaft 642 for sliding the chuck part is fixed to a frame 641, a bearing 629 to which a substrate 621 is fixed is engaged with this shaft 642, and is guided by this shaft 642. The chuck portion 620 moves back and forth. Further, a timing belt 643 is provided on the frame 641 for moving the chuck section 620 toward and away from the copy paper stack P.
is provided. The chuck section 620 and the timing belt 643 are fixed by an arm section 621a of the substrate 621. Pulleys 644 and 645 are fixed to both ends of the timing heald 643, and one pulley 644
is attached to a stepping motor 646. The output of the stepping motor 646 rotates the pulley 644 and moves the timing belt 643. Due to the movement of the timing heald 643, the chuck part 62 is identified to the timing belt 643 via the arm part 621a.
0 moves back and forth. A position sensor 650 is installed on the frame 641, and the substrate 6
A detection plate 630 is erected on 21 as a detection target, and this position sensor 650 detects the home position of the chuck section 620.

In the embodiment having such a configuration, when the stipple mode is started, first the drive belt 7 shown in FIG.
17 to the stay bluff 01 and paper pulling device 6
15 are integrally moved up and down, and as shown in FIG. Position sensor 7 in the figure
Based on the signal from 27, it is stopped at a position close to a predetermined bin 350. At this time, the solenoid 626 is turned off, and therefore both swing levers 622, 624 and chucks 623, 625 are placed in an open state.

Next, the stepping motor 646 rotates a predetermined amount to move the timing belt 643 and move the chuck section 620 forward toward the stack of copy sheets P.

By changing the rotational speed of the stepping motor 646, the speed at which the chuck portion 620 moves is controlled. In the case of this embodiment, the chuck unit 62O grips the aligned stack of copy sheets P with the chucks 623 and 625, and gradually accelerates at the start when moving back to the stipple position and gradually decelerates when stopped. This prevents aligned copy paper from becoming inconsistent due to inertia during acceleration and deceleration. When moving the same distance within the same time, uniform acceleration motion has the smallest maximum value of inertia, so in this example,
It accelerates and decelerates with constant acceleration.

When the chucks 623 and 625 are moved to a position where they can grip the stack of copy sheets P (FIG. 47), they are stopped there and at the same time, the solenoid 626 is turned on. By turning on the solenoid 626, the chucks 623 and 625 are closed as shown in FIG.
25 grips the edge portion of the copy paper bundle P. The movement at this time will be explained in more detail. That is, when the solenoid 626 is turned on, the lever 628 is pulled by the spring 627 hooked to the solenoid 62G, and the lever 62
The upper lever 622 engaged with the upper lever 622 rotates counterclockwise about the fulcrum 622a, and the upper chuck 623 lowers. Further, the lower lever 624 has a contact portion 624c with the upper lever 622.
The movement of the upper lever 622 is transmitted, the lever 624 rotates clockwise around the shaft 624a, the lower chuck 625 is raised, and the upper and lower chucks 623, 62
5 grips the copy paper stack P. The amount of movement of the upper chuck 623 and lower chuck 625 from their normal positions is determined by the lever 628.
It is determined by the length of the rotational fulcrum and the point of application of force point 2. In the case of this embodiment, when the moving amount of the chuck is expressed as a ratio, as shown in FIG.
The distance between and the fulcrum 622a is 92 mm, and the distance between the force point 622c and the rotation fulcrum 623a is 33 mm, so 9
2:33ζ2.79:1, and in the case of the lower chuck 625, the distance between the point of action 624b and the shaft 624a is 26 mm,
Since the distance between the force point 624c and the shaft 624a is 33 mm, the ratio of the amount of movement is 26:33=0.79:l,
The ratio of the moving distances of the upper chuck 623 and the lower chuck 625 is 2.79:0.79=3°53;1. In other words, when the upper chuck 623 moves downward by 3°5, the lower chuck 623 moves downward by 3°5.
25 will move up by 1. Also, the chuck force between the upper chuck 623 and the lower chuck 625 is provided by the solenoid 626.
It is determined by the force of the spring 627 attached to the. The spring 627 becomes longer and the chucking force increases as the number of copy sheets P held between the upper chuck 623 and the lower chuck 625 increases, thereby eliminating problems such as displacement due to insufficient chucking force.

In addition, if the chuck 623 or 625 grips only one corner of the copy paper, the fourth
As shown in Fig. 9, a moment is applied to the copy paper P, causing the copy paper P to tilt on the bin 350, causing the stipple position to vary, so the chucks 623 and 625 are branched as shown in Fig. 50. The copy paper P may be gripped at a plurality of locations to prevent the copy paper P from tilting even if a moment of inertia is applied.

Next, by reversing the stepping motor 646, the chuck unit 620 is moved back to its original position as shown in FIG. It is moved in parallel in the direction and drawn toward the stay bluff 01 side.

When the edge portion of the copy paper stack P is transported to a position where it can be stippled, it stops there. Thereafter, staples are driven into the edge portions of the copy paper bundle P by the stay bluff 01.

When the stay bluff operation is completed, the stepping motor 64
6 rotates in the normal direction, the chuck unit 620 moves forward, and after returning the staple rough copy paper P onto the bin 350, the solenoid 626 is turned off. As a result, the upper chuck 623 and lower chuck 625, which have been closed until now, will be opened. Thereafter, the chuck portion 620 is retracted to a predetermined position by rotating the stepping motor 646 in the reverse direction again. After that, the stay bluff 01 and the paper pulling device 615 move to the next bin 35.
0, where a stipple operation similar to that described above is repeatedly performed.

FIG. 51 is a front view of the paper alignment mechanism, and FIGS. 52 and 53 are front views of the paper alignment mechanism in an operating state. As shown in FIG. A bin fence 450 for aligning the copy paper stack P is provided at the opposing edge portion so as to rise from the bin 350. This bottle fence 4
The lower edge portion of 50 is rotatably attached to a support shaft 451 provided along the lower surface of the bin 350, so that the bin fence 450 can be tilted to the open position shown in FIG. It has become.

Both end portions of the support shaft 451 are rotatably supported by bearing pieces 456 formed downward at both end edge portions of the bottle 350. Further, a coiled spring 452 is attached to the support shaft 451.

Both winding end portions of the winding spring 452 are in contact with and locked against the lower surface side of the bottle 350 and the back side of the bottle fence 450, respectively, and the rotational force of the winding spring 452 causes the bottle fence 450 to move upward in the rising direction. It is beginning to receive force.

Further, the bin fence 450 is opened according to the vertical movement of the stay bluff 01 via a fence tilting member. This fence tilting member includes a fence movable plate 453 attached to the support shaft 451 side.
and the fence release plate 4 installed on the stay bluff 01 side.
It consists of 54.

A portion of the fence I+7i 453 is inserted into a fan-shaped hole in the one-piece portion 450a of the bin fence 450, and when the fence movable plate 453 is rotated downward, the fan-shaped hole in the one-piece portion 450a of the bin fence 450 is inserted. The lower part of the hole is abutted, so that the bin fence 450 is tilted according to the fence movable plate 453.

Furthermore, when the fence movable plate 453 is rotated upward, it is rotated away from the bin fence 450 side without contacting it, so the fence movable plate 453 is freely rotated. It happens.

Further, the rollers 454a of the fence release plate 454 are extended to a position where they come into contact with the fence movable plate 453, and the fence movable plate 454a is extended when the stay bluff 01 moves up and down.
The fence movable plate 453 is rotated by contacting the fence movable plate 453.

In the apparatus in this embodiment, when a sorting operation is first performed, the bin fence 450 is maintained in the upright position by the rotational force of a coiled spring 452, as shown in FIG. Accordingly, the edge of the copy IEP discharged onto the bin 350 comes into contact with the bin fence 450 to perform paper alignment.

When this sorting operation is completed, the above-mentioned stay bluff 0
1 begins to descend, stay bluff 01 example fence 'AH
The roller 454a of the Lt'rH 454 is brought into contact with the fence movable plate 453 of the bin 350 example. Then, the fence movable plate 453 is rotated to the lower position as shown in FIG. As the movable fence plate 453 rotates, the bin fence 450 is tilted against the rotational force of the coiled spring 452, thereby opening the bin 350. At this time, the bottle fence 450 and the fence movable plate 453
FIG. 2 - The bottle 350 has been pushed down to a lower position than the surface position A indicated by the dotted chain line. In this state, the stipple operation as described in the above embodiment is performed.

After the stipple operation is completed, the copy paper stack P is placed in the bin 350.
At the same time as the stay bluff 01 is returned to its original position, the stay bluff 01 is moved downward toward the next bin 350. Then, due to the downward movement of the stay bluff 01, the fence release plate 4
54 is removed from the fence movable plate 453 side, the bottle fence 450 is raised by the rotational force of the coiled spring 452 and returned to its original position. Such an opening operation and stipple operation of the bins 350 is similar to that of the sorted bins 35.
This is done for all 0's.

When stipple is performed on all copy paper stacks P,
The stay bluff 01 is raised and returned to the highest home position. The home position is located further above the first bin 350 located at the top. When the stay bluff 01 returns, the fence release plate 454 of the stay bluff 01 example moves to the fence movable plate 453.
However, in this case, as shown in FIG.
0 is not rotated at all. When the fence release plate 454 on the stay bluff 01 side is separated from the fence movable plate 453 side due to the upward movement of the stay bluff 01, the fence movable plate 453 is returned to the original position shown in FIG. 51 by its own weight.

FIG. 54 is a front view showing another embodiment of the paper alignment mechanism, in which an elastic body 455 that receives a fence movable plate 453 is installed on the bin fence 450 side. In such an embodiment, when the stay bluff 01 returns, when the fence movable plate 453 is rotated upward in an idling state, the fence movable plate 453 comes into contact with the elastic body 455 side and is received. The fence movable plate 453 is returned to its original position by the deflection repulsive force of the elastic body 455.

Fig. 55 is a perspective view showing another embodiment of the bin fence 450, Fig. 56 is a plan view of the embodiment of Fig. 55, Fig. 57 is a perspective view of the same embodiment in an operating state, and Fig. 58 is the same. 55 and 56, the fence 460 is pressed against each bin 350 and all bins 350 are
I try to use a single board for the alignment. The fence 460 is rotatably mounted at rotational supports 460a and 460b at the upper and lower ends. The rotation fulcrum 460b has a gear 460c, a gear 461 is meshed with the gear 460c, and the gear is driven by a drive motor 462.

When aligning the copy paper, the fence 460 is connected to the 55th, .
As shown in FIG. 56, the paper is aligned facing the bin 350. When all sorting is completed and stapling is to be performed, the fence 450 is rotated approximately 90 degrees as shown in Figures 57 and 58, leaving the bin 350 so that the copy paper P can be moved to the stipple position.

Among the signals exchanged with the copying machine, the signals sent from the copying machine to the stapler device 700 of the sorter include a sorter start signal, a copying machine discharge signal, a stipple start signal, a stipple end signal, a system reset signal, and a service signal. There are call reset ft number (S, C reset), status request signal, mode signal, size signal, output bin instruction signal, etc. Signals sent from stapler device 700 to the copying machine include model recognition signal, tray presence signal, stack over signal, bin over signal, cover oven signal,
The signals include a no staple signal, a JAM signal, a stipple impossible signal, a paper discharge signal, a WAIT signal, a BUSY signal, a mode end signal, a stipple count signal, and an abnormality signal.

The operation and control of the embodiment of the present invention will be described below with reference to flowcharts.

FIG. 60 is a flowchart of the overall operation of this embodiment. First, the mode signal sent from the copying machine is received in step 1-1). After copying has started, the size signal is received in step 1-2). Receive a sorter start signal (step 1-3). Upon reception of this mode signal, the sorter motor (when sorting is stacked) or Bruch motor (Bruf) is activated.

(at interrupt time) is turned on.

First, the blue mode (step 1-4) will be explained. After turning on the Bruch motor 117 in FIG. 1 (step 1-5), turning on the switching 5OL 107 in FIG.
7) The copy paper carried in from the entrance guide 102 (step 1-8) is discharged onto the upper draft tray 116 (step 1-9). After the copy paper is ejected, a paper ejection signal is sent to the copying machine (Step 1-10) to notify that the copy paper that has been carried in has been completely ejected. This operation is repeated until the copy is completed (step l-11).
). At this time, copy paper jam detection (not shown in the flowchart) is naturally performed. After copying is completed, the switch 5OL 107 turns off the Bruch motor 117 (step 1-12) and waits until the next copying operation.

Next, sort and stack modes will be explained.

After turning on the sorter motor 3]3 in Fig. 1 (Step 1
-13), can be oscillated by size signals, etc.

If it is determined that it is not possible, and if it is possible to swing (step 1-14),
The receiver moves the swing shaft 502 in FIG. 13 to the position corresponding to the size signal taken (step 115). Next, when the copy paper is ejected from the copying machine, the copying machine transmits a destination bin instruction signal and an ejection signal for the copy paper to be ejected (step 1-16). The destination bin 350 is determined by receiving the discharge signal (step 11).
7). Next, copy paper is carried in from the copying machine (step 1-18). After the paper is carried in, the entrance sensor is turned on, and at the timing when the population sensor is turned on, the deflection solenoid (SQL) determined by the discharge destination bin instruction signal is turned on (step 119), and the copy paper is guided to the bin 350. When copy paper is ejected (step 1-20), a paper ejection signal is sent to the copying machine (step 1-21), the bin 35
Notify the copying machine that the paper has been definitely ejected onto the top. Based on this signal, the copying machine determines the next destination and the destination after the jam has been cleared. Copy paper is ejected to bin 35.
0, and after an appropriate period of time has elapsed for the movement of the copy paper to settle down (for example, after 300 ms; step 1-22
), by turning on the size movement motor 515 in FIG. 13 and moving the swing shaft 502 (step 1-23), alignment in the direction perpendicular (horizontal) to the discharge direction is performed. In addition,
The timing for moving the swing shaft 502 is based on the detection of the trailing edge of the copy paper by the paper discharge sensors 322 and 324 (step 1-24).

After the swinging operation is completed, if the copy paper is curled, has scratches or folds on the surface, or is charged with a large amount of static electricity, it may rarely reach the end of the bin 350 or the bin fence 450.
There is copy paper that does not reach this point. Work is done to forcibly bring it to the edge.

Therefore, at the same time as the swing shaft 502 moves, the shifter 5OL
342 is turned on (Step 1-25), the rotating roller 333 contacts the upper surface of the paper, suppresses the curl, and forcibly moves it to the edge (for a certain period of time -200 m5; Step 1-26).

This shifting roller 333 is attached to each bin 350, and all of them are lowered at once by the shifting SQL 342. After completing this operation, turn off the 5QL342 (step 1
-27) Do.

The above operations are performed every time a copy is ejected, and the paper is sorted (step 1-28). When the sorting is completed in this manner, the sorter motor 313 is turned off (step 1-29) and stipple operation is performed. When the stapling start signal is received (step 1-30), the stapler device 700 is activated to stipple the stacked copy sheets (step 1-31). When the stapling operation is completed (step 1-32), the stapler device 7
00 and the swing shaft 502 move to the home position (step 1-33).

FIG. 61 is a flowchart explaining the alignment operation;
2 (al to d) are explanatory diagrams showing the operation of the swing shaft, in which the swing shaft 502 is positioned at a position based on the size signal (in this embodiment, the swing shaft 502 is moved to the position where the copy paper is ejected). axis 50
It is stopped in advance at a position 10 mm from the end face on the second side.

This is a position where the ejected copy paper P will not hit the swing shaft and cause jams, folds, etc. [Fig. 62 (a)
)), the copy paper is ejected, and after 300 ms, alignment is performed by swinging motion.

First, the size movement motor 515 (stepping motor) is moved so that the swing axis 502 approaches the paper by 25 mm, that is, the phase signal is applied in the CCW direction by the number of pulses equivalent to 15 mm.
10 from the port 803 and driven by the constant voltage driver 811 to move the swing shaft 502 [Step 2-1; FIG. 62(b)]. The speed at this time is 500
pps, and any speed that does not cause defects such as wrinkles, scratches, and folds on the copy paper P is sufficient. Due to this operation, the copy paper P discharged onto the bin 350 is pressed against the bin fence 450 by an excessive feed of 5 mm. This excessive pressing is to prevent variations in the length of the copy paper P and to achieve reliable alignment, and the
It doesn't have to be an appropriate value.

After pressing the copy paper P, it is stopped by - degrees (50 m5 in this embodiment; step 2-2). This is copy paper P
This is for stabilizing the motor 515 and for switching forward/reverse rotation of the size movement motor 515, and is not particularly necessary and does not require waiting.

Thereafter, the swing shaft 502 is moved 5 mm away from the paper, that is, by the number of pulses equivalent to 5 mm in the CW force direction [Step 2-3; FIG. 62(C)]. The speed at this time is 300 pps, which is slower than the speed at which the copy paper P returns due to excessive shearing, and may be at a speed that does not disturb the alignment once the copy paper P returns due to its elasticity.

Also, by returning 5 mm and stopping, the swing shaft 502 plays the role of a bin fence on the opposite side when it matches the paper width, and by stopping for another 50 ms (Step 2
-4), the copy sheets P are reliably aligned. Thereafter, the swing shaft 502 returns to the initial position in preparation for ejecting the next copy sheet (step 2-5; FIG. 61(d)) and stops (step 2-6). The speed at this time is sufficient as long as it is faster than the speed required to eject the next copy paper.

By the way, after the number of copy sheets stacked in the bin 350 exceeds the number of sheets that can be stippled (30 sheets in this embodiment), stapling of the ejected copy sheets is prohibited and sorting becomes obstructed. The I2 movement is stopped and the swing shaft 502 is retracted to the home position.

This operation will be explained below with reference to the flowchart in FIG. 63.

The number of copy sheets stacked on the bin 350 is detected (step 3-2) by counting when the copy sheets are discharged to the first bin (step 3-I). When it is determined that the discharge count value of the first bin exceeds the number of sheets that can be stippled (step 33), the swinging operation and the rolling motion are stopped (step 3-4), and the swinging shaft 502 is retracted to the home position (step 3-4). Step 3-5): From then on, no alignment is performed on the ejected copy paper. At the same time, stapling is also prohibited for previously ejected copy paper (step 3-6).

The stipple operation will be explained according to the flowcharts in FIG. 64 (al) to FIG. The operation starts by setting the sequence counter to 0 (step 4-1). First, the stapler device 700 at the home position is moved to the first bin to be stippled (
Step 4-2). After the stapler device 700 moves to the first bin, the operation proceeds based on the value of the stapling operation sequence counter described in FIG. 64 fal. When the stapler device 700 finishes moving to the first bin, the value of the stapling sequence counter is set from 0 to 1 (step 4-3).

When the value of the stipple sequence counter is negative (step 4-4), turn on the chuck motor (stepping motor) 646 as shown in FIG.
5) Advance the chuck section 620 in FIG. 45. Since the motor is a stepping motor, the amount of movement is determined by the number of pulses corresponding to the amount of movement (step 4-6). Also, the amount of movement at this time is from the home position of the chuck unit 620 (the position where the chuck home sensor 650 is on) to the position where the chuck unit 620 moves to the bin 35.
This is the amount by which a stack of copy paper above 0 can be chucked. When the chuck part 620 finishes moving forward (step 4-7)
, set 2 to the stipple sequence counter (step 4-8), and proceed to the next operation.

When the value of the stipple sequence counter is 2, the 64th
(Step 4-9) turns on the chuck SQL 626 as shown in C1, thereby chucking the stack of copy sheets. The stipple sequence counter is then set to 3 (step 4-10), and the next operation proceeds.

When the value of the stipple sequence counter is 3, the 64th
Start the timer (step 4) as shown in the figure (dl).
-11) Hold the state for 0.2 seconds, and after 0.2 seconds have passed (step 4-12), stop the timer (step 4
-13), set the stipple sequence counter to 4 (step 114), and proceed to the next operation.

When the value of the stipple sequence counter is 4, the chuck motor 646 is turned on, step 4-15), and the chuck unit 620 is moved to the home position, as shown in FIG. 64 (fe). The chuck home sensor 650 that detects the end of the home movement of the chuck part 620 is turned on (Step 4-16), the movement of the chuck part 620 to the home position is completed, and the chuck motor 646 is stopped (Step 4).
-17). The stipple sequence counter is then set to 5 (step 4-18), and the operation proceeds to the next step. At this time, the speed of the chuck motor 646 is uniformly accelerated so that the chucked stack of copy sheets does not shift.

In this example, it starts from 600pps and goes to 2000pps.
I'm slowing it up to s.

Also, the speed value is based on the size signal from the main unit and the value of the paper discharge counter explained in Figure 63. If the size is large or the number of sheets loaded is large, the moving speed is slowed down to prevent alignment during movement. This function prevents the stack of paper from shifting, and conversely increases the movement speed when the paper stack is small or the number of sheets loaded is small, thereby improving productivity.The information for changing the speed is as follows: Other factors include the thickness of the paper.

It goes without saying that the speed is the highest when there is no paper in the chuck, such as when the chuck is moving forward when the stipple sequence counter is 1 or when the chuck is moving backward when the stipple sequence counter is set to be described later. Furthermore, when chucking already stippled paper, such as when moving the chuck forward with stipple sequence counter 6, which will be described later, the paper will no longer shift, so problems such as scratches will not occur in the paper stack. Needless to say, it is relatively fast.

When the value of the stipple sequence counter is 5, the 64th
As shown in Figure (f), check the output of the paper presence/absence sensor 675 in Figure 48 (step 4-19), turn on the stipple motor when there is paper (step 420), and perform the stapling operation of the copy paper stack. . The end of the stapling operation is detected by the stipple home sensor 650 (Step 4-21), the stipple operation is ended (Step 4-22), and the stipple sequence counter is set to 6 (Step 4-23).
, proceed to the next operation. When the output of the paper presence/absence sensor 675 indicates that there is no paper, the stapling operation is not performed and the chuck 5
Turn off the OL626 (step 4-24) and set the stipple sequence counter to 8 (step 4-25)
), move on to the next operation.

When the value of the stipple sequence counter is 6 (step 4-26), the chuck motor 646 is moved forward again to return the stippled copy paper stack to the bin 350 as shown in FIG. 64(g) (step 4-26). 4-27). After feeding the set pulse amount (step 4-28), the chuck motor 648 is stopped (step 4-29), the chuck 5OL 626 is turned off (step 4-30), and the chuck arms 622 and 624 of the copy paper stack are released.

After that, start the timer (step 4-31), check the chuck SQL 626 response time for 0.2 seconds (step 4-32), and stop the timer (step 4-3).
3) Set the stipple sequence counter to 7. Step 4-34) and move on to the next operation.

When the value of the stipple sequence counter is 7, the 64th
As shown in Figure (h), the chuck part 620 is moved to the extent that it does not touch the bottle 350 in order to move to the lower bottle. As a result, the time from chucking to completing stipple per bottle can be shortened, and system productivity is increased. That is, the chuck motor 646 is started (step 4-35) and moved backward by the set pulse (step 4-35).
-36), and after the backward movement, the chuck motor 646 is stopped (step 4-37). Thereafter, the stipple sequence counter is set to 8 (step 4-38). When the stipple is completed, that is, when the stipple sequence counter is 8, the vertical movement motor 720 is turned on as shown in FIG. 64 (11) (step 4-38). 39), raise the stapler device 700. Then, the upper and lower home sensors 72
9 is turned on (step 4-40), the vertical movement motor 720 is turned off (step 4-41). Thereafter, the stipple sequence counter is set to 0 (step 4-42).

The operations of the stipple sequence counters 0 to 8 described above are performed until the stipple is completed.

Thereafter, the size movement motor 515 is turned on, and when the size home sensor 501 is turned on, the size movement motor 515 is turned off. The home movement of the stipple device 700 and the movement of the swing shaft 502 may be performed simultaneously, or the order may be reversed to that of this embodiment.

Next, the function of slowing up and slowing down vertical movement will be explained. This function gradually increases the movement speed at the start of vertical movement, moves at a constant speed when it reaches the set value, and when the vertical movement stops, gradually decreases the movement speed from before the bin position to stop, and then increases the movement speed to the set value. When it reaches this point, it moves at a constant speed and stops at the stop bin position.
