Description

  The present invention relates to a booklet manufacturing apparatus such as a calendar, and more particularly to a booklet manufacturing apparatus capable of automatically binding a plurality of paper sheets using a paper binding tool.

  As a means for binding booklets such as calendars and notebooks, metal binding metal fittings formed in a spiral or ring shape have been widely used. However, since metal binding metal fittings cannot be incinerated, these booklets When disposing of the booklet, it is necessary to remove the binding bracket from the paper booklet body, separate it and dispose of it, and there is a problem that it is very complicated. There is a possibility of being discarded as garbage, and there is a problem from the viewpoint of environmental protection.

Therefore, in recent years, a paper binding tool having an advantage that the whole can be incinerated without requiring separation work at the time of disposal has been developed and supplied to the market.
JP 2005-111835 A Japanese Patent No. 3754601 JP-A-8-318687

  As shown in FIG. 2, a paper binding tool described in Japanese Patent Application Laid-Open No. 2005-111835 basically has a base 21 and extends from the base 21 in a predetermined direction. And a plurality of claw-like portions 20 formed by slightly bending the distal end portion 20a to the outside, the paper binding tool having such a structure. No. 19 is difficult to apply to an automatic machine in the booklet manufacturing process, and the attachment work (binding operation) to the booklet body must be performed manually, and the booklet cannot be mass-produced. There is.

  This point will be described in detail. For example, a conventional metal fitting formed by bending or curving a wire in a comb shape so that a number of claw-shaped portions are adjacent to each other at equal intervals in the longitudinal direction is manufactured. By processing the raw material (wire) using a dedicated machine, it is possible to make the shape of the claw-shaped part constant, and to align the position of each tip cleanly, and to each tip The state where the parts are aligned can be maintained for a long time.

  Therefore, when the binding metal fitting is attached to the booklet main body (that is, a bundle of paper sheets) and the operations for binding the paper sheets are performed, the binding holes of the bundled paper sheets (sequentially spaced on one side of each paper sheet). The claw-like portions can be accurately inserted into each of the plurality of holes) by mechanical means. Then, by further bending or curving each claw-shaped portion, it is possible to bind the sheets firmly so that each paper sheet does not fall off.

  On the other hand, the paper binding tool 19 as shown in FIG. 2 is subjected to an external force at the time of transfer, storage, etc., even if the positions of the tips 20a can be neatly aligned immediately after manufacture. Or due to a change in humidity or the like, the shape (curvature) of each claw-shaped portion 20 may vary, and the positions of the respective tip portions 20a may not be aligned, resulting in a random pile shape. In such a case, it becomes very difficult to insert the respective claw-shaped portions 20 into the binding holes of the bundled paper sheets by mechanical means.

  In addition, after inserting the claw-like portions 20 into the binding holes of the bundled paper sheets, it is necessary to bond the tip portions 20a to the base portion 21, but the positions of the tip portions 20a are not aligned. In some cases, it becomes difficult to bond automatically by mechanical means. Therefore, at present, booklet production (binding operation) using such a paper binding tool 19 is exclusively performed manually.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a booklet manufacturing apparatus that can automatically mount and automatically bond a paper binding tool by mechanical means. And

  The booklet manufacturing apparatus of the present invention includes a paper binding tool having a plurality of nail-like portions extending in a curved state from a base portion in a predetermined direction, and a front end portion of the nail-like portion mounted on the booklet body. An automatic bonding means for automatically bonding the base, and a support for holding the paper binding tool mounted on the booklet body. The automatic bonding means includes a base and a tip of the paper binding tool. Is formed by two members sandwiched in close contact with each other at a predetermined pressure from the outside, and of these two members, the top edge of the member that contacts the tip of the claw-shaped portion is aligned It is characterized in that a flange is formed.

  The support preferably has a portion holding the paper binding tool configured as a curved surface with a curvature corresponding to the curvature of the claw-shaped portion, and the opening direction of the binding hole in the booklet body (booklet paper) It is configured to move appropriately in a direction that coincides with the direction perpendicular to the leaves), and the shape is corrected by pressing the paper binding tool sandwiched by the automatic bonding means in the major axis direction of the ellipse. It is preferable to be configured.

  The booklet manufacturing apparatus of the present invention is a case where the shape (curvature) of the nail-like portion of the paper binding tool to be applied varies, and the positions of the tip portions are not aligned and are in a random pile shape. Even if it exists, the booklet can be bound by accurately aligning the positions and automatically bonding them.

  Further, the support is configured to press the paper binding tool in the major axis direction of the ellipse, thereby correcting the shape of the paper binding tool so that the nail-like portion is in a state close to a perfect circle. be able to.

  Hereinafter, an embodiment of a “booklet manufacturing apparatus” according to the present invention will be described with reference to the accompanying drawings. In the booklet manufacturing apparatus according to the first embodiment of the present invention, after the paper binding tool having a plurality of claw-like portions extending in a curved state from the base portion in a predetermined direction is automatically attached to the booklet main body. It is configured to automatically bond the tip and the base of the paper binding tool. Basically, it is a means for automatically mounting the paper binding tool on the booklet body to be processed (automatic mounting) Means), automatic bonding means for adhering and binding the tip of the nail-shaped portion of the paper binding tool attached to the booklet main body to the base, a control device, other peripheral devices, and an accessory It consists of parts.

  FIG. 1 is a side view of an automatic bonding means which is one of the most important components in a booklet manufacturing apparatus according to the present invention, and is an explanatory view of a bonding process of a paper binding tool. In the present embodiment, the automatic bonding means is constituted by an ultrasonic horn 1 that contacts an object and applies ultrasonic vibrations, and an abutment plate 2 that is disposed as a “backing” on the opposite side of the object. Yes. In FIG. 1, 3 is a support, 18 is a booklet body, 18a is a binding hole, and 19 is a paper binding tool.

  When the front end portion 20a of the claw-shaped portion of the paper binding tool 19 is advanced into the binding hole 18a of the booklet main body 18 by automatic mounting means (not shown), and the mounting of the paper binding tool 19 on the booklet main body 18 is completed. For the subsequent bonding process, as shown in FIG. 1 (1), the support 3 is set in a fixed position, and the paper binding tool 19 is held by the support 3 while being attached to the booklet body 18. The

  Next, the horn 1 moves from the outside of the base 21 (right side in FIG. 1) toward the base 21 and from the opposite side (outside of the tip 20a of the claw-like part, left side in FIG. 1) of the claw-like part. The abutment plate 2 moves toward the distal end portion 20a, and the base 21 and the distal end portion 20a are sandwiched between the horn 1 and the abutment plate 2 from the outside with a predetermined pressure as shown in FIG. It will be in the state which adhered to the shape.

  In this state, ultrasonic vibration emitted from an ultrasonic oscillator (not shown) is transmitted to the horn 1, and ultrasonic vibration is applied from the horn 1 to the base portion 21 and the distal end portion 20 a. A thermoplastic (heat seal) adhesive is applied to either the inner side surface (the surface abutting on each other) of the tip portion 20a or the base portion 21, or both inner side surfaces, and is generated along with ultrasonic vibration. The adhesive is temporarily softened by the heat to be applied, and the tip portion 20a and the base portion 21 are bonded.

  As shown in FIG. 1 (1), the paper binding tool 19 has a shape of each nail-like portion due to an external force acting at the time of transfer or storage, or due to a change in humidity or the like. In this case, the base 21 and the tip 20a are simply sandwiched between the horn 1 and the abutment plate 2 in some cases. However, in the booklet manufacturing apparatus according to the present embodiment, the upper edge of the plate 2 is not sufficient. The flange 2a is formed, and when the tip 20a and the base 21 are sandwiched between the abutment plate 2 and the horn 1, the position of the tip 20a is aligned by the flange 2a. Ring size It can be suitably avoid the problem of uneven.

  In addition, when the base 21 and the tip 20a are sandwiched between the horn 1 and the abutment plate 2, the paper binding tool 19 tends to become a vertically long ellipse as shown in FIG. 1 (2). In the booklet manufacturing apparatus of the present embodiment, the support 3 is appropriately moved up and down (moves appropriately in a direction that coincides with the binding hole opening direction in the booklet main body). As shown in FIG. 1 (3), the nail-like portion of the paper binding tool 19 is pushed up by pushing up the paper binding tool 19 in a state sandwiched between the lower side and pressing in the vertical direction (the major axis direction of the ellipse). The shape is corrected so that is close to a perfect circle.

  The support 3 is configured such that a portion (upper surface) for holding the paper binding tool 19 is a curved surface having a curvature corresponding to the curvature of the claw-shaped portion of the paper binding tool 19. Furthermore, even when the shape is corrected by pressing in the vertical direction, the formation of the bent portion and the deviation of the curvature in the nail-like portion are avoided, and the nail-like portion of the nail-like portion is entirely surrounded. It can be corrected to an ideal shape so that the curvature is constant.

  In addition, when the step of pushing up the paper binding tool 19 from below by raising the support 3 is configured to be performed before adhesion by ultrasonic waves, only the effect that the shape of the paper binding tool 19 can be corrected. In addition, an advantageous effect can be expected even when trying to align the position of the tip portion 20a by the flange 2a of the contact plate 2.

  This point will be described in more detail. When the uneven tip end portion 20a is sandwiched by the abutment plate 2 having the flange 2a formed on the upper edge, among the plurality of tip end portions 20a, the position is higher than the standard position. For the tip portion 20a at a high position, the height position of the tip portion 20a is regulated and aligned with the standard position by the engagement of the flange 2a, but the tip portion at a position lower than the standard position. For 20a, the flange 2a may not work effectively. At this time, when the support 3 is raised and the paper binding tool 19 is pushed up from below, the tip portion 20a at a position lower than the standard position is biased toward the flange 2a within the range of rigidity of the claw-shaped portion. As a result, the distal end portion 20a located at a position lower than the standard position can be aligned with the standard position.

  In the present embodiment, as described above, the ultrasonic welding horn 1 and the plate 2 are used as the automatic bonding means, but the bonding method applied in the booklet manufacturing apparatus of the present invention is not necessarily limited. The method is not limited to the method using ultrasonic waves, and a pair of heating plates for softening the heat seal adhesive can be applied instead of the horn 1 and the plate 2. In this case, among the pair of heating plates, the heating plate that comes into contact with the front end 20a side of the paper binding tool 19 is formed with a flange at the upper edge, like the contact plate 2 shown in FIG. When 20a and the base 21 are sandwiched between the heating plates, it is preferable that the position of the tip 20a is aligned by the flange.

It is a side view of the automatic adhesion | attachment means (horn 1, this board 2) in the booklet manufacturing apparatus which concerns on this invention, Comprising: Explanatory drawing of the adhesion process of a paper binding tool. The perspective view of the paper binding tool 19. FIG.
