Description

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.
This invention relates to a paper aligning device for an automatic stapler that can align sheets discharged onto a paper discharge tray when the stapler performs a clinch 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 failure of the conveyance means that conveys the paper.
If you clinch at a certain position with the above-mentioned specially developed automatic stapler or an automatic stapler configured with a commercial product for office use, not only will the paper not be neatly stapled due to irregularities, but some parts of the paper will be stuck in the stapler. There is a problem that occurs when the needle comes off and cannot be stapled.

Therefore, this invention allows for neat binding by automatically aligning the sheets when clinching, and is especially effective for automatic stapler paper output or center type (reference or center type when copying). The purpose is to provide alignment equipment.

(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. The automatic stapler clinches the sheets with a stapler that moves back and forth, and is capable of moving in synchronization with the center on both sides of the paper output tray in order to align the side edges of the sheets discharged to the paper output tray. The present invention is characterized in that it is a paper aligning device for an automatic stapler in which aligning plates are provided oppositely and these aligning plates are linked to the stapler.

(E) Function In the automatic stapler paper aligning device of the present invention, when the stapler moves during clinching, both aligning plates move synchronously to the center side, and this movement moves each aligning plate to the side of the paper. Align the paper by pressing against the edges, and at the same time clinch the paper at the clinching position with the stapler.

(f) Effects of the Invention As a result of the above, according to the present invention, the sheets can be aligned using the left and right aligning plates during clinching, so the sheets can be neatly aligned and bound.In particular, since they are aligned from both sides, the center This is more effective for types of copiers that eject paper.

In addition, the paper alignment structure consists of an alignment plate linked to a moving stapler, so a dedicated drive source is not required.
It has a simple structure and 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 has ten paper discharge trays 11... stacked in the vertical direction, and each of the above-mentioned paper discharge trays 11... has bins 12.. attached on both sides.
12 or 13' engages with the spiral carved on the circumferential surface of the elevating rotary body 13', 13, and one rotation of the elevating rotary body 1313 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 5 formed by the upper and lower guide plates 14.14,
The sheets discharged by the upper and lower paper discharge rollers 16, 16 are received one by one in each paper discharge tray 11 and stacked.

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.

For this purpose, the automatic stapler 20 is also arranged obliquely in accordance with the inclination of the paper discharge tray 118 (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.

Furthermore, alignment plates 22 and 23 constituting a paper alignment device are provided upright on both sides of the above-mentioned paper discharge tray 11a.
2.23 moves synchronously to the center side, and aligns the sheet 2 on the sheet discharge tray 11a by abutting it from both sides.

One of the above-mentioned alignment plates 22 is connected to the interlocking frame 24 in an upright state, and the above-mentioned interlocking frame 24 has a three-dimensional shape in which the front end side is formed into a planar shape and the rear end side is formed into a sideways shape. is connected to a sliding frame 33 of the stapler 32, which will be described later, so as to be interlocked with the movement of the stapler 32 toward the clinch position A.

Furthermore, a rack rod 25 extending toward the center of the paper discharge tray 11 is connected to the tip of the interlocking frame 24 described above.

A side-faced rack rod 26 is connected to the above-mentioned alignment plate 23, and the lower horizontal portion of this rack rod 26 is supported by an appropriate support structure so as to be slidable only in the width direction at the bottom of the guide frame 17 of the sorter 10. , the horizontal part of the rack rod 26 and the above-mentioned rack rod 25 are opposed to each other, and racks 27 and 28 are carved on the opposite side, and an idler pinion 29 is interposed between them, mesh.

Note that the above-mentioned pinion 29 is connected to the above-mentioned guide frame 17.
Bearing appropriately at the bottom of.

Aligning plates 22 and 23 of the paper aligning device configured in this way
As will be described later, when the stapler 32 moves toward the clinch position A of the paper 21, the alignment plate 22 is moved toward the center via the interlocking frame 24.

Moreover, when the above-mentioned interlocking frame 24 moves to the center side,
Via the rack rod 25, pinion 29, and rack rod 26,
The other alignment plate 23 also moves toward the center.

As a result, both aligning plates 22 and 23 move synchronously to the center, and this movement allows both side edges of the paper 21 to be aligned.
When the sheets 21 are aligned, the stapler 32 clinches the sheets 21 to the clinch position.

Note that when the stapler 32 returns to its original position, both aligning plates 22 and 23 are also returned to their standby positions.

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 the same mechanical parts 30 and 31.

The above-mentioned sliding frame 33 is the clinch mechanism section 30 when viewed from above.
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 placing section 34 of the stapler 32 is bent, and the side on the moving mechanism section 31 side is high, and four guide rollers 35 are placed inside. It is pivoted (see Figure 6).

The above-mentioned guide rollers 35... are fitted to 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 1o, so that the sliding frame 3
3 is supported so that it can slide from the standby position to the clinch position A, and a spring 39 stretched between the fixed frame 36 and the sliding frame 33 urges the sliding frame 33 toward the anti-clinch position side (outside). ing.

The movement from the standby position to the clinch position [A] is driven by the aforementioned moving mechanism section 31, and the return is driven by the biasing force of the aforementioned spring 39.

The interlocking frame 24 of the above-mentioned one aligning plate 22 is connected to the vertical portion of the mounting section 34 of the above-mentioned sliding frame 33, and is interlocked with the sliding frame 33 moving the stapler 32 to the clinch position A. The interlocking frame 24 also moves in the same direction.

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.
The clinch levers 42 are 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 on the above-mentioned fixed frame 40 by a support shaft 43.

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 rotating cam 44 rotates once, the pin 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, by moving the aforementioned clinch lever 42 downward and causing its clinch roller 47 to press 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 comes into contact with a stopper 52 fixed to the fixed frame 36 when the stapler 32 moves to the clinch position. 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 swinging lever 61 pivotally supports a roller 63 which is in contact with the above-mentioned rotating cam 6°, and by locking one end of a spring 64 to the fixed frame 40 and the other end of the spring 64 to the swinging lever 61, the roller 63 can be rotated. The swing lever 61 is urged toward the rotating cam 60 so that the lever 63 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 contact the front face of the swing 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 or the pressing piece 65 can be brought into contact with each other. 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, when the rotating cam 60 makes one rotation and the swinging lever 61 makes one reciprocating motion, the sliding frame 33 also makes one reciprocating motion. By doing so, the stapler 32 can clinch the paper 21 at the clinch position A.

Furthermore, as described above, the stapler 32 is at the clinch position Δ
In synchronization with the movement to the side, the alignment plates 22 and 23 of the paper alignment device also move to the center of the paper output tray 11, and with this movement, the paper 21 on the paper output tray 11a is brought into contact with it from both sides. , the sheets 21 are aligned, so even if the sheets 21 sent out from the copying machine are ejected at irregular positions, the sheets 21 are aligned.
I can spell out the numbers 1 neatly.

Further, since the structure for aligning the paper sheets 21 is constructed in conjunction with the movement of the stapler 32, 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.
