Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a paper sheet storage device that can be used in a base paper discharge device of a rotary copying machine.

(b) Prior art As a paper sheet storage device that can be used for the original paper ejection device of a rotary copying machine, for example, the Japanese Patent Publication No. 58-18916
The method described in the publication No. 1 is proposed.

The paper sheet storage device described in the above publication is
A liner (receiving member for paper sheets) having an L-shaped cross section is provided on the downstream side of a pair of mutually meshing spur gears for conveyance (sheet conveyance means). It is configured to store used base paper. When the inside of the liner is filled with used base paper, the liner is removed upward and the base paper is discarded together with the liner, but there is no means for holding the base paper at the upstream end of the liner. Because they are not prepared,
When the liner was removed in an upward direction, there was a risk that the upstream end of the base paper would remain inside the apparatus body.

In addition, a paper sheet storage device has been proposed in which a lid body is attached to a housing-shaped paper sheet receiving member so as to be openable and closable, and the lid is opened when the receiving member is attached to the device main body, and the lid is closed when the receiving member is removed from the device main body. (1987-)
(See Publication No. 169961).

Note that the lid described in this publication is only for closing the receiving member, and is not for holding paper sheets.

(C) Problems to be Solved by the Invention As mentioned above, in the conventional technology, since the used base paper has highly viscous printing ink attached to it, the upstream end of the used base paper is attached to the conveying gear or the main body of the device. When the liner is removed upwardly, the upstream end of the base paper remains stuck inside the apparatus main body, resulting in a problem in that the paper cannot be ejected smoothly.

In addition, as mentioned above, used base paper has highly viscous printing ink attached to it, so if this end remains inside the main body of the device, it is not only difficult to remove it, but also This ink adheres to the fingertips of the operator who is trying to remove the base paper,
This paper ejection work was extremely troublesome.

Furthermore, the lid described in Japanese Utility Model Application Publication No. 59-169961 is intended only to close the receiving member and not to clamp paper sheets. ) is separated from the rotating body, so even if paper sheets are caught in the lid,
its upstream end depends outside the receiving member;
There is a possibility that problems similar to those described above may occur.

When the paper sheet is discharged and transferred by the rotating body, the paper sheet is bent in a meandering manner on the downstream side of the rotating body, so that a long portion hangs down outside the receiving member.

The present invention aims to solve the various problems of the above-mentioned prior art all at once.

(d) Means for Solving the Problems The present invention provides at least a pair of disks or cylinders that are in contact with each other at a part of the circumference for conveying paper sheets, and are arranged on rotational axes that are parallel to each other. A paper sheet receiving member is removably attached to the downstream side along the paper sheet conveying direction of the paper sheet conveying means installed respectively, and a paper sheet receiving member is detachably attached to the upstream end of the paper sheet receiving member on the upstream side. In a paper sheet storage device in which an extending clamping claw that clamps paper sheets is openable and closable, the clamping claw is opened when the receiving member is attached to a paper sheet conveying means side. The tip of the lever is located on the side of the flat surface of the disk or cylinder, and the holding claw is configured to close when the receiving member is separated from the main body of the device. It is something.

(e) Effect In the present invention, since the upstream end of the receiving member is provided with means capable of holding paper sheets, when the receiving member in which paper sheets are stored is removed from the main body of the apparatus, If the paper sheets are clamped by the clamping means, no part of the paper sheets remains inside the apparatus main body.

Further, since the tip of the holding claw of the receiving member is located on the side of the plane of the disk or cylinder,
The upstream end (terminus) of the paper sheet conveyed and discharged by the rotating body is held by the holding part, and when the receiving member is removed from the apparatus main body, the upstream end of the paper sheet is does not hang outside the receiving member.

... and the stepped pins 7... are base paper peeling claws arranged so as to face each other. These base paper peeling claws 9, 9, 9 extend parallel to the rotational axis of the plate cylinder 2, and are fixed to a support shaft 10 rotatably mounted on the chassis of the apparatus main body 1. (10) is bell crank 11 and connecting rod 1
2 to the plunger 14 of the solenoid 13. Therefore, when the plunger 14 performs a pulling action, the bell crank 11 moves toward the support shaft 10.
The plate is slightly rotated counterclockwise (FIG. 1) about , and the sharply formed tips of the paper peeling claws 9, 9, 9 come close to the peripheral side wall of the plate cylinder 2. When the plate cylinder 2 rotates clockwise in this state, the tips of the peeling claws 9, 9, 9 touch the mounting ears of the base paper 4 and the plate cylinder 2.
The used base paper 4 is inserted between the plate cylinder 2 and the base paper mounting portion 6 of the plate cylinder 2, and the used base paper 4 is sequentially peeled off from the plate cylinder 2.

A base paper storage device 15 as a paper sheet storage device is provided downstream of the base paper peeling claws 9, 9, 9 along the base paper transport direction. The raw paper storage device 15 includes a container holding member 18, which is provided with a plurality of pairs of mutually meshing spur gears 16...17... on the upstream end thereof as paper sheet conveyance means, and a container holding member 18 that is detachable from the container holding member 18. It is composed of a housing-shaped container 19 as a receiving member which is freely attached. Note that the container holding member 18 is detachably attached to the main body 1 of the apparatus.

The spur gear pairs 16...17... are connected to a drive shaft 20 and a driven shaft 21 extending parallel to the rotational axis of the plate cylinder 2.
The drive shaft 20 is connected to the rotating shaft of the motor via a transmission gear 20a fixed to the end thereof and a reduction gear 22 rotatably mounted on the device main body 1. There is. The transmission gear 20a and the reduction gear 22 are configured to be able to approach and separate from each other, and when the container holding member 18 is inserted in the left direction (upstream direction) with respect to the device main body 1, they mesh with each other, and when they are inserted in the right direction (downstream direction), they mesh with each other. direction), they will separate.

The container holding member 18 is provided with outwardly projecting pins 23 on both side walls thereof.
is a recess 2 provided in the chassis of the device main body 1.
4, this container holding member 1
8 is fixed to the main body 1 of the device.

Further, a hole 2 of an appropriate diameter is provided in the side wall of the container 19.
5 is opened, and a ball 40 which is biased to protrude toward the container 19 is attached to a portion of the container holding member 18 corresponding to this hole 25. This ball 40 has a slightly larger diameter than the hole 25, and by fitting into the hole 25, the container 19 is fixed to the container holding member 18.

A cover 27 with a substantially L-shaped cross section is attached to the upper part of the container 19 so that it can be opened and closed, and one end is fixed to a swing shaft 226 that is rotatably attached to the upper part of the downstream side of the container 19. L-shaped first levers 28, 28 are fixed to both ends of the swing shaft 26. When the container 19 is inserted into the device main body 1, the upper edge of the horizontal arm portion of the first levers 28, 28
Some pins 29 protruding inside the device main body 1,
Cam parts 28a, 28a that slide with the cover 29 are formed, and pressing pieces 28b, 28b for manually opening the cover 27 are also formed.

Further, the other end of a first torsion spring 30, one end of which is locked to the side wall of the container 19, is locked to the acute arm portion of the first levers 28, 28,
The cover 27 is rotated counterclockwise by the torsion spring 30, that is, the free end of the cover 27 is rotated toward the container 1.
It is elastically biased in a direction toward the upstream end of 9.

A clamping claw 31 that can selectively come into contact with the upstream edge of the container 19 is fixed to the free end of the cover 27 by rivets 32, 32. Further, guides 33 extending from the container holding member 18 are provided between the spur gears 16 at positions facing the drive shaft 20.

When the container 19 is inserted into the device main body 1, the first lever 2 is pressed as described above.
The cam portions 28a, 28a of 8, 28 are in contact with the pins 29, 29 of the device main body 1, and the cover 27 is rotated slightly clockwise against the first torsion spring 30 with its pivot shaft 26 as the center. Maintain a biased posture. At this time, the holding claws 31, 31 are
inserted between the drive shaft 20 and the driven shaft 21,
and is in sliding contact with the lower part of the drive shaft 20 (fourth
figure). Therefore, the used base paper 4 conveyed by the pair of spur gears 16...17...
It is stored in the container 19 without getting stuck on 1 and 31.

On the other hand, if the container 19 is even slightly removed from the device main body 1, the cam portion 2 of the first lever 28
8a and the pins 29, 29 of the device main body 1 are separated, the cover 27 is attached to the first torsion spring 3.
The elastic force of 0 causes the pivot shaft 26 to be rotated counterclockwise about the pivot shaft 26 . Therefore, the free end portions of the clamping claws 31, 31 are pressed against the upstream edge of the container 19, and the used base paper 4 is held against both 31, 19.
(Fig. 5).

Note that after the container 19 is completely removed from the device main body 1, the pressing piece 28 of the first lever 28
b, 28b with your fingertips, the cover 2
7 rotates largely clockwise around its pivot shaft 26 and becomes completely open. At this time, after the first torsion spring 30 is once compressed,
Since the cover 27 passes through the consideration point and is opened again, the once opened cover 27 maintains that position (6th
figure). Therefore, once the cover 27 is completely opened, the used base paper 4 filled in the container 19 can be discharged without continuing to press down the pressing pieces 28b, 28b.

Further, inside the downstream inner wall 19a of the container 19, a detection plate 3 whose upper end edge is fixed to a support shaft 34 extending parallel to the swing shaft 26 of the cover 27 is provided.
5 is provided. At the end of this support shaft 34 is a second lever 3 as shown in solid lines in FIGS. 7 and 8.
6 is fixedly installed, and a magnet piece 37 is fixed to the free end of this second lever 36. A magnetic sensor 38 made of a reed switch, a Hall element, etc. is provided at a portion of the device main body 1 corresponding to the magnet piece 37. A second torsion spring 39 for rotationally biasing the detection plate 35 in a clockwise direction is attached to the support shaft 34, and a second torsion spring 39 is attached to the support shaft 34 to rotate the detection plate 35 clockwise.
The free end of the detection plate 35 is biased toward the upstream side until it is full (FIG. 7). At this time, the second lever 36 is also biased clockwise, and the magnetic sensor 38
is in contact with the magnet piece 37. Therefore, the magnetic sensor 38 outputs a signal indicating that the container 19 is not yet filled with the base paper 4.

However, when the container 19 is filled with used base paper 4, the detection plate 35 is pressed downstream by the base paper 4, and the detection plate 35 pushes the support shaft 34 against the second torsion spring 39. The center is offset counterclockwise (Fig. 8). Then, the second lever 36 is also biased counterclockwise, and the magnet piece 37 is separated from the magnetic sensor 38, so that the magnetic sensor 38 detects that the container 19 is full of used base paper 4. A signal is output. By this output, starting of the original paper storage device 15 is prohibited, and a display to that effect is displayed on the operation panel (not shown) of the device main body 1.

Note that if the container 19 is not fully inserted into the device main body 1, the magnet piece 37 and the magnetic sensor 3
8 does not make contact, and in this case as well, the magnetic sensor 38 outputs the same signal as when the container 19 is filled with the base paper 4.

That is, this magnetic sensor 38 detects whether or not the container 19 is filled with used base paper 4, and also detects whether or not the container 19 is fully inserted into the main body 1 of the apparatus. However, in any of the above cases, it is not preferable to operate the original paper storage device 15, so the configuration is such that activation thereof is prohibited as described above.

Then, the used base paper 4 peeled off from the plate cylinder 2 by the base paper peeling claws 9, 9, 9 is transferred to the spur gear pair 1.
6...17... are transported and stored in the container 19,
When the container 19 is filled with the base paper 4, the detection plate 35 is biased toward the downstream side. Then, the magnetic sensor 38 outputs a signal indicating that the base paper 4 is full, and a message indicating this is displayed.The operator follows the display and pulls out the container 19 toward the downstream side.
The upstream end of the last stored base paper 4 is taken out to the outside while being held between the holding claws 31, 31 fixed to the cover 27 and the upstream end of the container 19.

In this case, in the unlikely event that the base paper 4 is the spur gear pair 16...17...
When the base paper 4 becomes entangled, the entangled base paper 4 can be easily removed from the outside by removing the container 19 and then removing the container holding member 18 downstream from the apparatus main body 1.

In this embodiment, spur gear pairs 16, 17, etc. are used as means for conveying the base paper 4, but rollers with knurling on the circumferential side or rubber rollers may be used instead.

It is also possible to provide a clip that can be opened and closed at the upstream end of the container 19 as a means for holding the base paper, and to open and close this clip from the outside.

Further, in this embodiment, the paper sheet storage device is used in a rotary copying machine, but it goes without saying that it can be used not only in a rotary copying machine but also in various devices for storing paper sheets, such as a shredder.

(G) Effects of the Invention In the present invention, since the upstream end of the paper sheet receiving member is provided with means capable of holding the paper sheets, the receiving member in which the paper sheets are stored can be moved downstream. There is no possibility that the upstream end of the paper sheet will remain inside the apparatus main body when it is removed in the direction of the paper sheet.

Therefore, when this paper sheet storage device is employed in a rotary copying machine, used base paper can be reliably removed.

Further, in the present invention, since the holding claws of the receiving member are located on the side of the plane of the disk or cylinder, the upstream end (used The terminal end of the paper sheet is held by the holding part, and when the receiving member is removed from the apparatus main body, the upstream end of the paper sheet does not hang down outside the receiving member.

Therefore, the printing ink adhering to the base paper does not adhere to the inside of the apparatus main body or the operator's fingertips and stain them.
