Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a bookbinding applicator for pasting other signatures or postcards, single-cut sheets, etc. to a bookbinding signature. In order to prevent the adhesive application line from bending or shifting from the specified position along the edge of the paper when applying the adhesive to bond paper sheets such as signatures, postcards and cut sheets to each other. The present invention relates to a bookbinding paper sheet pasting machine having a paper sheet pasting guide.

(Prior art) As shown in Fig. 3, a bookbinding sticker can glue and stick paper sheets 4 and 4a of various sizes. If they are different, after the paper sheet is fed onto the transport table 3 of the applicator by the suction device and the pawl device, the paper sheet is likely to be bent, and the paper sheet fed in the correct posture has the paper sheet end portion. It is bent or displaced due to the pressure contact force of the gluing means applied to the work, which requires skill in adjustment. When the paper sheet on the side to be glued is bent by the push pin 2 and glued,
The glue is not glued to the correct position parallel to the edge of the paper sheet 4 but is glued diagonally, which causes a problem in the sticking quality.

(Purpose of the Invention) The present invention guides a paper sheet on the gluing side correctly in the transportation direction so that the paper sheet is not bent and pushed on the transportation table of the pasting machine and is not glued to the edge of the paper sheet. It is intended to provide a bookbinding paper sticking machine capable of accurately performing gluing along a book.

(Structure of the Invention) The present invention includes a push-out means for pushing push-out pins on an endless chain at regular intervals so as to push out a paper sheet for sticking,
A main guide that is provided parallel to the feeding direction and guides one side of the paper sheet, and a gluing means that is provided on the main guide side and that glues parallel to the edge of the paper sheet that is conveyed by the pushing means; In a bookbinding paper sticking machine provided with a polymerization means for superposing the following paper sheets on the upper side of the formed paper sheet and pasting them together, in parallel to the conveying direction relative to the main guide and the gluing means, The front stage is a guide having an L-shaped cross section, the rear stage is a U-shaped guide having a U-shaped cross section, and the middle of the guide is a wing guide for introducing a paper sheet in which the upper plate of the U-shaped guide is open toward the front stage. It is a bookbinding paper sticking machine equipped with.

(Operation of the Invention) In the present invention, a guide is provided in parallel with the conveying direction at a position of the gluing section that faces the portion where the gluing roller is in pressure contact with the paper sheet. The application head provided in the gluing means is, for example, a rubber roller if the means is roller application means,
The wire gluing means is a flexible member such as a stretchable spring wire. Usually, such a flexible member is pressed with a comparatively weak force to a portion of the paper sheet corresponding to the glue application to carry out the gluing. However, the displacement stress due to the pressure contact strain of the roller is applied to the paper sheet at the pressed portion. Even if a bending stress is generated on the paper sheet while the paper sheet is being applied and conveyed while hanging and pushing the paper sheet with the push pin, the paper sheet is conveyed in the conveying direction by the guide provided opposite to the main guide and the gluing means. Can be guided in parallel with each other, so that the paper sheet is not bent, and is linearly parallel to the end of the paper sheet 4 as shown in FIG. As a result, the glue application line 10 can be formed in a dot shape, and the occurrence of bending of the application line can be prevented.

(Embodiment) A preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a general bookbinding machine, in which endless chains 1 are provided with push pins 2 at equal intervals. 3, a pushing means provided so as to project from 3 and a sticking paper sheet 4 such as a postcard to be pushed by the pushing pin 2 along the edge parallel to the conveying direction, a bond, an aqueous solution synthetic glue, and a maroon type adhesive. An adhesive roller 5 for applying an adhesive such as a coating agent or an application head 5a such as a wire for intermittent vertical movement at a predetermined timing is provided, and a flat pressure type pressure applying means provided downstream of the adhesive applying means. It is to be crimped by. The main guide plate 8 is provided on one side of the transport table 3 along the transport direction.

FIG. 2 is a perspective view of a bookbinding sheet sticking machine to which a sticking guide 7 of the present invention is attached, and the guide 7 is a main guide plate 8.
To the upper surface of the transport table 3 in parallel and parallel to the fixed table with a space slightly smaller than the size of the pasted paper sheet, or mounted on the lower side of the transport table 3 (see FIG. (Not shown) is attached so as to be swingable and repeatable in the direction perpendicular to the conveying direction. The guide 7 is a guide 7a having an L-shaped cross section at the front stage and a U-shaped guide 7c having a rear cross section at the rear stage.
In the middle thereof, there is provided a wing guide 7b for introducing a paper sheet having a shape in which the upper plate of the U-shaped guide is opened toward the front stage direction. First of all, the pasting paper sheet 4 such as a postcard should be a pasting guide 7
It is fed by a suction device (not shown) between the L-shaped guide 7a and the main guide plate 8 and is conveyed forward by the push pin 2 while being abutted against the main guide plate 8 at that time. One end of the insert sheet 4 is regulated and conveyed by the sticking guide 7, and when the guide 7 moves down into the wing 7b of the guide 7 and is carried into the channel of the U-shaped guide 7c, the application of the gluing means 5 is performed. An adhesive is glued to the end edge of the sticking paper sheet 4 on the main guide 8 side by the head 5a, and then the sticking paper sheet 4a such as a signature is fed onto the guide table 9 and The signature sheet 4a is superposed on the postcard sheet 4 from the upper side of the guide table 9 while being pushed by the push pin 2 together with the paper sheet 4 which has been glued previously.

(Advantages of the Invention) The present invention is a bookbinding paper sheet pasting machine provided with a guide facing the main guide for paper sheet feeding and the gluing means, such as a postcard and the like. In the case of gluing in a line shape to the end of the pasted paper sheet to be pasted to another paper sheet, the guide can prevent the paper sheet from bending due to the pressure contact stress to the paper sheet of the gluing means, Even in the case of gluing in a dot shape, gluing can be performed correctly in parallel along the edge of the pasted paper sheet, which is effective for improving the quality of the pasted product and is of practical value.
