Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document stitching machine for stitching together a large number of documents.

Conventionally, when binding thick documents, it was difficult to staple without staples, so for example,
As shown in the qttas publication, after placing a document on a movable mounting table and fixing it on the document mounting table using a paper holding mechanism provided on this mounting table, drilling and stabilizing are performed. ing. However, in a document binding machine having such a structure, since the surface of the stand serves as a reference surface for binding, the distance required for the perforation drill and the staple to descend becomes extremely long. For this reason, with the conventional 4) M stapler, there are many accidents in which the tip of the punching drill becomes eccentric during punching and the hole cannot be drilled accurately, or the punching drill breaks in the middle, and the tip of the punch and the staple do not match. However, there were cases where it was difficult to drive the staples, resulting in m & c.

In view of the above-mentioned problems with drilling and stitching of type 4 binding machines, this book@Akira is a type 4 binding machine that has a short downward distance for drills and staples, and has fewer drilling errors, stable driving, and mistakes. This is a proposal for a machine. To summarize the present invention, there is provided a document stitching machine comprising a perforation station and a staple and seam station, which are provided adjacent to each other in the direction of movement of a movable table on which a barb is attached, in which the perforation station is directly below a drill that can be lowered. A paper holder is provided on the movable stand facing toward the paper holder, a document holder that can be raised toward the paper holder is mounted on the movable stand, and a document is held between the document holder and the paper holder. It is located in a document stitching machine that performs punching and stitching.

Hereinafter, details of one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a document binding machine according to the present invention.

It is equipped with a base / that can be placed on a table top, on which a vertical support wall 2 is provided, and a bearing block 3 is fixed to the front surface of this support wall. This bearing block 3 has a pair of rotating sleeves adjacent to each other in a direction perpendicular to the plane of the paper in FIG. A and #B are rotatably supported, and these rotating sleeves! A, 4I
Driven pulleys jA and jB in the middle of H and drive pulleys 7A and 7B of the drill drive motor 6 fixed to the back of the support wall
V bell) fA and gB are connected between the two. Further, inside each of the rotating sleeves 4 (A, 4!B), there is a pivot shaft IOA that can rotate together with the corresponding rotating sleeves 4ZA and 4!B and is sent vertically by a rack 9, which will be described later.
10B is supported to be slidable in the vertical direction with respect to the rotating sleeve IIA and Hiroshi 7B.

Therefore, the drilling station A is formed by jetting the drills 12 onto the lower end chucks l/ of the pivot shafts #7A and 10B, respectively.

At a position adjacent to the front of this drilling station A, that is, at a position perpendicular to the alignment direction of the drill 12.

A stitching station B is provided.

As shown in FIG. 2, the binding station B is made as a block that can be opened and closed around the line axis /3 on the side of the support wall pN, and when this binding station B is opened to the virtual water preparation position.

The lower part or pivot axis 10A of the drilling station A.

The lower end of 10B is opened forward, allowing the drill 12 to be easily replaced.

Stapling station B includes a vertical staple guide /j that guides the downward direction of staples /4I, and a pair of mounting walls /4 and /7 located on both sides in front of this stable guide /S. Between these walls /A and /, there is a staple mount to which a large number of staples can be attached. The tensioned suppressing member 20 urges the staple guide ISK.

On the other hand, a vertical movement motor/and a staple driving motor 2 are installed in the space between the additional walls /4 and /7. The vertical motor 2/ rotates, via a gear train 23, a binion 21I meshed with a rack 9 that vertically moves the pivot shafts #7A and 10B. Further, the staple driving motor 22 is connected to a staple driving plate 26 which can move up and down along the front surface of the stable guide 15 via a gear train 2S.
Rack 27A integrated with.

Drives pinions 2gk and 2gB that mesh with 27B.

Returning to FIG. 1, a movable table 2q is provided on the base l and is movable in the front and back direction along the upper surface of the base l. Documents A paper presser 3/ is provided which can come into contact with the upper surface of the paper. Also, this movable table λ
A document mounting table 33 supported by pantographs 32k and 32B so as to be raised upwards is provided at the upper part of the t.

This document tray 33 is lifted toward the paper presser 3/ by the movement of a slider 3'l that moves the movable end of the bank graph 32B, and the movement of this slider 3'l is a vertical motor 3S built into the lower part of the movable table 29.
This is done by a feed screw 36 driven by. What, the aforementioned document mounting table? 3 is operated by motor 37! Although a mechanism for stable cutting similar to A-7g data publication is included, this staple mounting mechanism is not the gist of the present application, so please refer to the same publication.

Since the document stitching machine has the above-described structure, in order to stitch documents, move the movable table 29 to the position shown by the solid line in FIG. When the document mounting table 33 is raised by operating the 3S, the document X is clamped between the paper presser 31 and the document 411 table 33. Therefore, drilling can be performed by lowering the drill/tool, but since the position of the 4F is determined by the position of the paper presser 3, the document cannot be placed on the mounting table 1 using the clamp mechanism. Compared to the traditional clamping structure, the descending distance of the drill is much smaller.

The chances of drilling errors, drill damage, and stable driving errors are much lower.

Next, while maintaining the raised position of the document area 1 unit 33, the moving motor 30 moves the movable table λ9 from the position shown in FIG. 1 to the position shown by the solid line in FIG. It is located directly below the stable 14t. In this case, the moving distance of the movable base knob is a small distance, as can be seen from FIG. 7, so the positioning accuracy is high, and staples can be driven reliably.

As is clear from the above description, according to the present invention, it is possible to provide a document binding machine with a short descending distance for the drill and the stable, thereby reducing drilling errors and drill breakage accidents due to eccentricity of the drill, and reducing the number of drill breakage accidents due to eccentricity of the drill. A device with fewer typing errors can be achieved.
