DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to an automatic stapler that clinches sheets discharged from a copying machine with a stapler.
The present invention relates to a paper alignment device for an automatic stapler that can align sheets discharged onto a paper discharge tray when the stapler performs a clinching operation.

(b) Conventional technology Conventionally, there have been automatic staplers that clinch paper ejected from a copying machine, but this conventional device uses a stick that was specially developed to be attached to the copying machine. Was.

For this reason, it is not only expensive, but also large in size, and when attached to a copying machine, it becomes bulky.

As a means to solve this problem, we developed the use of a stapler that is commercially available for office use.

(c) Problems to be Solved by the Invention However, the paper ejected from the copying machine is not always ejected to a fixed position due to the movement of the conveying means that feeds the paper, so the above-mentioned specially developed automatic stapler Or, if you use an automatic stapler made of commercially available office products to clinch at a certain position, not only will the sheets not be stapled neatly due to misalignment, but some of the sheets will come off the stapler and become stapled. The problem is that there are cases where this is not the case.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a paper aligning device for an automatic stapler that can neatly staple sheets by automatically aligning the sheets during clinching.

(d) Means for Solving the Problems This invention allows the clinch position of sheets discharged from a copying machine onto a paper output tray to be moved from a standby position set on one side of the paper output tray to the clinch position. This is an automatic stapler that clinch sheets with a stapler that moves back and forth, and a base wall for aligning the discharged sheets is erected on the side edge of the paper output tray on the side opposite to the stapler, and the stapler The present invention is characterized in that the paper aligning device of an automatic stapler is provided with a backing plate that aligns the sheets by applying them to the base wall.

(E) Function In the automatic stapler paper aligning device of the present invention, when the stapler moves during clinching, the backing plate moves in the same direction in conjunction with this movement to press the paper against the base wall of the opposing paper output tray. to align the sheets, and at the same time, the stapler clinch the sheets at the clinching position.

(f) Effects of the Invention As a result of the above, according to the present invention, since the sheets can be aligned between the base wall and the backing plate during clinching, the sheets can be neatly aligned and bound.

Further, since the paper alignment structure is constructed by connecting a moving stapler with a backing plate, no dedicated drive source is required, the structure is simple, and it works reliably.

(g) Examples of the invention An embodiment of the present invention will be described in detail below based on the drawings.

The drawings show an automatic stapler for a copying machine in which an automatic stapler is incorporated into a sorter of a copying machine, and the sorter 10 shown in FIGS. 1 and 2 includes a sheet aligning device.

In the above-mentioned sorter 10, the sorter 10 stacks 10 paper discharge trays 11 in the vertical direction, and each of the above-mentioned paper discharge trays 11... has pins 12 attached on both sides.
．． 12 engages with a spiral carved on the circumferential surface of the lifting rotor 13.13, and one revolution of the lifting rotor 13.13 causes
Go up or down one by one.

After the paper copied by the copying machine (not shown) is discharged into the paper discharge path 15 formed by the upper and lower guide plates 14 and 14,
Each paper ejection tray 11 receives and accumulates sheets ejected by upper and lower paper ejection rollers 16, 16 one by one.

It should be noted that the configuration of the sorter 10 described above is a well-known technology, so its details will be omitted.

The automatic stapler 20 incorporated in the above-mentioned sorter 10 has a paper discharge tray 11a supported by the above-mentioned elevating rotary body 13.
A clinch operation is performed on the stacked sheets 21 (21a, 21b).

For this purpose, the automatic stapler 20 is also arranged obliquely in accordance with the inclination of the paper discharge tray 11a (see FIG. 1).

As shown in FIG. 2, the above-mentioned automatic stapler 20 is disposed on one side of the front end of the paper ejection tray 11, and is set at a standby position at a position that does not interfere with paper ejection. Move to clinch position tilA.

Further, a base wall 22 constituting a paper alignment device for aligning the sheets 21 is provided upright on the side edge of each paper discharge tray 11 facing the automatic stapler 20 described above. By applying the , you can align the paper.

On one side of the paper discharge tray 11 facing the base wall 22 described above, a backing plate 23 constituting a sheet aligning device is located, and the plate 23 is connected to a support frame 24 and connected to the support frame 24. 24 is connected to a stapler, which will be described later, and in conjunction with the movement of this stapler, the paper 21 described above is attached to the base wall 2.
2 and performs the aligning action.

Next, the configuration of the above-mentioned automatic stapler 20 will be explained.

That is, as shown in FIGS. 3 and 4, the above-mentioned automatic stapler 20 has a clinch mechanism section 30 and a moving mechanism section 31 arranged side by side, and the sliding frame 33 on which the stapler 32 is mounted is configured by these. It is formed across both side structural parts 30 and 31.

The above-mentioned sliding frame 33 is the clinch mechanism section 30 in plan view.
The side is short and the moving mechanism section 31 side is long (the third
(see figure), and the cross section is U-shaped (see figure 4).
When viewed from the back, the side on the clinch mechanism section 30 side is low and horizontal, and the mounting section 34 of the stapler 32 is bent and formed, and the side on the moving mechanism section 31 side is high (with four guide rollers on the inside). It is pivoted at an angle of 35-1° (see Figure 6).

The guide rollers 35 described above move the sliding frame 33 to the standby position by fitting into the upper and lower rail sides 38 and 38 of the C-shaped rule 37 fixed to the fixed frame 36 installed on the sorter 10. The sliding frame 33 is supported by a spring 39 tensioned between the fixed frame 36 and the sliding frame 33. It is biased toward the needle loading position.

The movement from the standby position to the clinch position A is driven by the movement mechanism 31, and the movement from the standby position to the needle loading position is driven by disengaging the movement mechanism 31, thereby driving the movement of the spring. It is driven by a biasing force of 39.

The above-mentioned support frame 24 is connected to the mounting portion 34 of the above-mentioned sliding frame 33, and the above-mentioned support frame 24
In conjunction with moving the stapler 32 to the clinch position A, the support frame 24 and the backing plate 23 also move in the same direction.

When the backing plate 23 is moved, the sheets 21a on the paper discharge tray 11a are pressed against the base wall 22 side like the moved sheets 21b, and the sheets 21 are aligned.

The aforementioned clinch mechanism section 30 is configured as follows.

That is, in FIGS. 3, 4, and 5, the upper part of the inverted U-shaped fixed frame 40 fixed to the sorter 10 side has a drive shaft 41 extending to the other moving mechanism part 31. The drive shaft 41 is controlled one rotation via an appropriate motor and reduction gear (not shown).

Further, a clinch lever 4 is provided at the bottom of the drive shaft 41 described above.
This clinch lever 42 is formed by connecting a pair of left and right sides in an inverted U shape on the front end side, and each of the base ends is pivotally supported by a support shaft 43 to the above-mentioned fixed frame 40.

A pair of eccentric rotary cams 44 are fixed to the aforementioned drive shaft 41 in correspondence with the aforementioned clinch levers 42, and a cam groove 45 is carved on the outer surface of the rotary cam 44.
5 is fitted with a pin 46 implanted in the clinch lever 42 (see FIG. 5).

Therefore, when the rotary cam 44 rotates once, the bin 46 is guided by the cam groove 45, so the clinch lever 4
The free end side of 2 moves up and down by 1.

A clinch roller 47 is installed on the free end side of the above-mentioned clinch lever 42, and the shaft portion 48 of the clinch roller 47 engages in a long groove 49 to enable vertical displacement. It is biased towards the side.

Therefore, when the aforementioned clinch lever 42 moves downward and the clinch roller 47 presses down the stapler 32, the paper 21 can be clinched at the clinch position A with the staples.

A tongue piece 51 is connected to the lower front end of the mounting portion 34 on which the stapler 32 is placed, and this tongue piece 51 contacts a stopper 52 fixed to the fixed frame 36 when the stapler 32 moves to the clinch position A. Then, the stapler 32 is positioned at the clinch position A.

The aforementioned moving mechanism section 31 is configured as follows.

That is, in FIG. 3, FIG. 4, and FIG. 6, a substantially heart-shaped rotating cam 60 is fixed to the shaft end of the drive shaft 41, and the upper end of the swinging lever 61 is fixed close to this rotating cam 60. is swingably supported on the fixed frame 40 by a support shaft 62.

The above-mentioned swing lever 61 pivotally supports a roller 63 which is in contact with the above-mentioned rotating cam 60. One end of a spring 64 is locked to the fixed frame 40, and the other end of the spring 64 is locked to the swing lever 61. The swing lever 61 is urged toward the rotating cam 60 so that it is always in pressure contact with the rotating cam 60.

Therefore, when the rotary cam 60 is controlled to rotate once, the swing lever 61 will reciprocate once.

A pressing piece 65 is attached to a support shaft 66 at the lower end of the swing lever 61 mentioned above.
A contact piece 67 is connected to the upper front surface of the pressing piece 65 to abut the front face of the swinging lever 61, and is biased by a spring 68.

A contact lever 69 is located on the bottom upper surface of the sliding frame 33 at a position facing the pressing piece 65,
The middle part of the abutment lever 69 is pivotally supported by a support shaft 71 on a support member 70 which is erected and fixed on the bottom upper surface of the sliding frame 33.
A roller 72 that comes into contact with the above-mentioned pressing piece 65 is pivotally supported on the rear end side, and the lower surface of the front end side is brought into contact with a stopper 73 connected to the above-mentioned support member 70, so that the roller 72 comes into contact with the pressing piece 65. The abutting position is regulated, and a spring 74 presses and biases it.

Therefore, when the aforementioned swing lever 61 swings forward, the contact lever 69 is pushed by the pressing piece 65, the sliding frame 33 moves to the clinch position A side, and the swing lever 61 retreats backward. Then, the sliding frame 33 can also be retreated to the standby position by the spring 39 urging the sliding frame 33.

Therefore, one rotation of the rotary cam 60 causes the swinging force to be -61
When the slide frame 33 makes one reciprocation, the movement of the moving mechanism 31 is synchronized with the operation of the clinch mechanism 30, so that the stapler 32 moves to the clinch position A of the paper 21. can clinch.

Furthermore, as described above, the stapler 32 is moved to the clinch position A.
In synchronization with the movement to the side, the backing plate 23 of the sheet aligning device also moves to the base wall 22 side of the paper discharge tray 11 that faces it, and at the time of this movement, the paper 21 on the paper discharge tray 11a
Since the sheet a is moved and aligned against the base wall 22 like the sheet 21b, the force of the sheet 21 sent out from the copying machine (
Even if the sheets 21 are discharged in the negative alignment (1 position), the sheets 21 can be neatly aligned and bound.

In addition, the alignment structure of the paper 21 is such that the moving stapler 32
Since the abutment plate 23 is connected to the back plate 23, there is no need for a dedicated drive source, the structure is simple, and it works reliably.

Note that the paper alignment device of the present invention is not limited to the configuration of the embodiment.
