Description

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

Conventionally, when stitching together thick documents, it is difficult to suddenly insert staples, so for example, as shown in Japanese Patent Publication No. 55-46845,
A document is placed on a movable mounting table, and after the document is fixed on the mounting table by a paper holding mechanism provided on the mounting table, perforation and stapling are performed. However, in a document binding machine having such a configuration, the surface of the mounting table serves as a reference surface for binding, so that the distance required for the perforation drill and the staple to descend is extremely long. For this reason, with conventional document binding machines, 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 midway through, and the punching and staple tip positions do not match. In some cases, it became difficult to drive staples.

In view of the above-mentioned problems in perforation and binding of document binding machines, the present invention is proposed for a document binding machine in which the required distance for lowering the drill and staples is small, and there are fewer perforation errors and staple driving. . To summarize the present invention, there is provided a document binding machine comprising a perforation station and a stapling station, which are provided adjacent to each other in the moving direction of a movable base on which documents are attached, in which the movable base faces directly below a drill that can lower the perforation station. A paper holder that is pressed downward by a biasing means such as a spring is provided on the top of the paper holder, and a document mounting table that can be raised toward the paper holder is mounted on the movable table, and the document mounting table and the paper holder are mounted on the movable table. This is a document binding machine that performs perforation and binding while the document is held between the presser feet.

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

In FIG. 1, the document stitching machine according to the present invention is
A base 1 that can be placed on a tabletop is provided, and a vertical support wall 2 is provided on the base 1, and a bearing block 3 is fixed to the front surface of the support wall 2. A pair of rotating sleeves 4A, 4B adjacent to each other in a direction perpendicular to the plane of the paper of FIG. , 5B and drive pulleys 7A, 7B of the drill drive motor 6 fixed to the back surface of the support wall 2, V belts 8A, 8B are stretched. Further, inside each of the rotary sleeves 4A, 4B, there are pivot shafts 10A, 10B which can rotate together with the corresponding rotary sleeves 4A, 4B and are sent vertically by a rack 9, which will be described later, relative to the rotary sleeves 4A, 4B. It is supported to be slidable in the vertical direction.

Therefore, the drilling station A is formed by attaching the drills 12 to the lower end chucks 11 of the pivot shafts 10A and 10B, respectively. A stitching station B is provided at a position perpendicular to the direction.

As shown in FIG. 2, the stitching station B is made as a block that can be opened and closed around the butterfly shaft 13 on the front side of the support wall, and when the stitching station B is opened to the position shown by the imaginary line,
The lower part of the drilling station A, that is, the pivot axis 10
The lower ends of A and 10B are opened forward, and the drill 1
2 can be easily replaced.

The stapling station B has a vertical staple guide 15 that guides the downward direction of the staples 14.
and a pair of mounting walls 16 and 17 located on both sides of the front of the staple guide 15. A staple mounting base 18 to which a large number of staples 14 can be attached is provided between these mounting walls 16 and 17, and the staples 14 on this staple mounting base 18 are stapled by a pressing member 20 pulled by a spring 19. It is urged toward the guide 15.

On the other hand, a vertical movement motor 21 and a staple driving motor 22 are installed in the space between the mounting walls 16 and 17. The vertical motor 21 is connected to the gear train 2
3, a pinion 24 meshed with a rack 9 for vertically moving the pivot shafts 10A, 10B is rotated. Further, the staple driving motor 22 is connected to a pinion 28 through a gear train 25 that engages with racks 27A and 27B that are integral with a staple driving plate 26 that can move up and down along the front surface of the staple guide 15.
A and 28B are driven.

Returning to FIG. 1, a movable table 29 is provided on the base 1 and is movable in the front-rear direction along the upper surface of the base 1. At the rear of the movable base 29, which can be moved to the position shown by the solid line in FIG. 1 and the position shown by the solid line in FIG. 3 by a moving motor 30 installed at the rear of the base 1,
A paper presser 31 is provided that can come into contact with the upper surface of the document X indicated by the imaginary line. Further, a document mounting table 33 is provided on the upper part of the movable table 29 and is supported by pantographs 32A and 32B so as to be able to be raised. This document mounting table 33 is connected to the pantograph 32.
The movable end of the slider 34 is moved upward toward the paper presser 31 by movement of the slider 34, and the movement of the slider 34 is carried out by a vertical movement motor built into the lower part of the movable table 29. This is done by a feed screw 36 driven by 35. Note that the document table 33 has a built-in staple cutting and bending mechanism similar to that of Japanese Patent Publication No. 56-7845, which is operated by a motor 37, but this staple cutting and bending mechanism is not the gist of the present application. Please refer to the same bulletin.

Since the document stitching machine has the above-described structure, in order to stitch documents, the movable table 29 is moved to the first position.
Place the document X in the position indicated by the solid line in the figure, and
When the document X is placed on the top and the vertical movement motor 35 is operated to raise the document mounting table 33, the document X is clamped between the paper presser 31 and the document mounting table 33. Therefore, drilling can be performed by lowering the drill 12, but the position of the document is determined by the paper presser 31.
Compared to the conventional structure in which the document is clamped by a clamping mechanism on the mounting table on which the document is placed, the descending distance of the drill is much smaller, preventing drilling errors, drill damage, and staple driving. There are far fewer mistakes made.

Next, while maintaining the raised position of the document table 33, the movable table 29 is moved by the moving motor 30 from the position shown in FIG. 1 to the position shown by the solid line in FIG.
The perforation a is located directly below the staple 14 as shown in the fourth figure. In this case, the moving distance of the movable base 29 is a small distance as understood from FIG. 4, so the positioning accuracy is high and the staples 14 can be reliably driven.

As is clear from the above description, according to the present invention, it is possible to provide a document stitching machine with a short descending distance for the drill and staples, thereby reducing drilling errors and drill breakage accidents due to eccentricity of the drill, and reducing staple driving errors. It is possible to achieve a device with less
