This is known. For example, in the paper laminator of Patent Literature 1, when joining the folded bent paper after adhesive coating, a plurality of vacuum rollers arranged in the vertical direction are used, and the paper is rotated while the vacuum roller is rotated. By sucking, the paper is always guided until bonding. Thereby, even if it sends out paper at high speed, it is unlikely that a paper will jump out after falling, and paper can be bonded together in the state in which the edge part coincided cleanly. Moreover, when it presses by a press plate and bonds papers together, it slides to the position which piled up the paper after adhesive application on the rail.

In addition, for example, in the paper half-folding adhesive coating bookbinding apparatus of patent document 2, the half-folding mechanism which folds rectangular paper in half, the adhesive application mechanism which adheres and adheres to the half-folded paper, and a base plate I) Pressing the half-folded papers superimposed on the sheet is pressurized to bond the papers from the folds of paper to bonding. In this bookbinding apparatus, in order to guide the left and right edges of the half-folded paper after adhesive application sent out from the adhesion | coating application roller which comprises an adhesion | coating application mechanism, a pair of paper width regulation guide arrange | positioned in reverse H shape is used. As a result, both corners of the folded paper sequentially stacked on the base are made to coincide.

It is comprised so that it may bond with respect to the printing paper 8 pushed out last time.

As shown in FIG. 7, in the paper-binding machine 1 of this example, by the reaction force when the printing paper 8 is received by the rail 6, it is attached to both side ends 802 of the printing paper 8 by the reaction. The tip end of the bent contact portion 52 of the pair of leaf springs 5 is held in the state where the bite is held, and the pressing press plate 71 keeps the printing paper 8 in close contact with the rail 6. It is configured to push out.

In addition, the pair of leaf springs 5 are held in the state of being bitten into both side ends 802 of the printing paper 8 until the moment the printing paper 8 is bonded by the pushing press plate 71. The bent end 801 of the printing paper 8 is brought into close contact with (6).

As shown in FIG. 8, the laminated bookbinding machine 1 of the present example can bond a plurality of printing papers 8 and bind them together, and as shown in FIG. 9, between the printing papers 8. Plural bonding is also possible through the thick paper 80 and bookbinding is possible.

For the bonding of the printing paper 8 of the present example, an acetic acid emulsion type adhesive 83 is used, for example. By using the thick paper 80, the absorbency of the water in the adhesive 83 adhesively applied to the printing paper 8 can be improved, so that the inexpensive acetic acid emulsion type adhesive 83 can be easily used. Can be.

As a result, as shown in FIG. 9, the thick paper 80 is bonded at a position apart from the bend end 801 of the printing paper 8 by a predetermined width to alternate the thick paper 80 and the printing paper 8. It can be bonded by binding.

By the way, when the printing paper 8 after adhesive coating was placed on the rail 6, when the adhesive agent on the outer surface 82A of the printing paper 8 adhered to the surface of the rail 6, the extrusion press plate When the printing paper 8 is pushed out by the 71, the adhesive attached to the rail 6 becomes a slip resistance, which may cause the slippage of the printing paper 8 to be bad.

On the other hand, in this example, the structure which used the pair of leaf springs 5 is prevented from having a problem with bookbinding under the influence of the adhesion of the adhesive agent to the rail 6.

When bookbinding is performed by the paper-binding machine 1 of this example, the bending end 801 is provided in the clearance gap formed by the drum 31, the some paper-feeding roller 34, the adhesive application roller 32, and the pressure roller 33. First, the printing paper 8 folded in half is inserted from the printing paper 8 by rotating the drum 31, the plurality of paper feed rollers 34, the adhesive coating roller 32, and the pressure roller 33. Adhesively apply | coated to one outer side surface 82A.

And the printing paper 8 adhesively apply | coated is sent out to the some suction roller 4, and it is sent out on the rail 6 by the some suction roller 4. As shown in FIG. At this time, in this example, the tip of the bent contact portion 52 of the pair of leaf springs 5 is elastically deformed in contact with the printing paper 8 so that the feeding of the printing paper 8 is carried out in a predetermined width direction position [ Center position between frames 2A]. And when the printing paper 8 abuts on the rail 6, the sticking of the printing paper 8 is prevented by the some suction roller 4. In addition, by the reaction force when the printing paper 8 is received by the rail 6, as shown in FIG. 7, a pair of leaf springs 5 are provided at both side ends 802 of the printing paper 8. The leading end of the bent contact portion 52 of the bite enters. As a result, the state where the pair of leaf springs 5 are elastically deformed is maintained, and the pair of leaf springs 5 prevents the printing paper 8 from jumping off the rails 6.

Subsequently, the pushing paper plate 71 pushes the printing paper 8 sent out over the rail 6 to the predetermined lamination position 702 and joins the printing paper 8 pushed out last time. At this time, the pair of leaf springs 5 in contact with the printing paper 8 is elastically deformed while being bitten into both side ends 802 of the printing paper 8, and the printing paper 8 The leaf spring 5 is guided and pushed to the lamination position 702 by being bited.

Thereby, even when the adhesive agent 83 which flowed away from the outer side surface 82A of the printing paper 8 adheres on the rail 6, the printing paper 8 is turned over by the extrusion press plate 71. In the movement joined to the printing paper 8 pushed out to the paper, the tip of the bent contact portion 52 of the pair of leaf springs 5 is bitten into both side ends 802 of the printing paper 8 (8) can be prevented from jumping from above the rail (6). For this reason, when the printing paper 8 pushed out the last time in the lamination | stacking position 702 and the printing paper 8 pushed out by the pushing press plate 71 are joined, the bending end of printing paper 8 comrades is carried out. The positions of the 801 and both side ends 802 can be effectively matched to a predetermined widthwise position (center position between the frames 2A).

For this reason, according to the laminated bookbinding machine 1 of this example, bookbinding of the half-folded printing paper 8 can be performed by making the position of end surface 801, 802 effectively match.

(Example 2)

This example is an example devised so as to prevent the printing paper 8 from being bent (twisted) when the printing paper 8 is adsorbed by the suction roller 4, especially when the printing paper 8 is thin.

A pair of wires 53 to be pulled and tension applying means 54 for applying a predetermined tension to the pair of wires 53 are provided.

The wire 53 of this example is a φ0.5 mm wire made of stainless steel, and is hung up and down with respect to the frame 2A at a position facing the plurality of suction rollers 4 arranged on the pair of inner frames 2A. It is. The wire 53 is disposed in the vicinity of both side ends 802 of the printing paper 8, specifically, at a position for pressing the range within 3 mm from the side end 802 of the printing paper 8. In addition, it is more preferable that the position pressed by the wire 53 is a position of 1 to 1.5 mm from the side end 802 of the printing paper 8.

The tension applying means 54 of the present example is a tension spring 54, and the tension spring 54 is attached to each of the pair of wires 53. As shown in FIG.

As shown in FIGS. 10-12, the wire guide 55 for fixing the arrangement position of the wire 53 is provided in the up-and-down position of the frame 2A. One end of the wire 53 is fixed to the wire guide 55 or the frame 2A, the other end of the wire 53 is mounted to one end of the tension spring 54, and the other end of the tension spring 54 is the frame. It is fixed to 2A.

By changing the spring constant of the tension spring 54, the tension applied to the wire 53 can be adjusted to the target tension.

The paper binding machine 1 of this example has both side ends of the printing paper 8 by the wire 53 subjected to the tension by the tension spring 54 when the suction roller 4 feeds out the printing paper 8. It is comprised so that the vicinity of 802 may be pressed against the suction roller 4. Moreover, the paper-binding machine 1 is comprised so that the pushing press plate 71 may push out from between the wire 53 and the suction roller 4, while bending the printing paper 8, as shown in FIG. have.

In the laminated bookbinding apparatus 1 of this example, bookbinding is performed using the thin paper (about 0.1 mm) as the printing paper 8. The thickness of the printing paper 8 can be 0.08-0.12 mm. In addition, for the printing paper 8, if the paper quality is soft, a thickness thicker than 0.12 mm can also be used.

In this example, the other structure of the paper-binding machine 1 is the same as that of Example 1 above.

When bookbinding is performed by the paper-binding machine 1 of this example, the bending end 801 is provided in the clearance gap formed by the drum 31, the some paper-feeding roller 34, the adhesive application roller 32, and the pressure roller 33. First, the printing paper 8 folded in half is inserted from the printing paper 8 by rotating the drum 31, the plurality of paper feed rollers 34, the adhesive coating roller 32, and the pressure roller 33. Adhesively apply | coated to one outer side surface 82A.

And the printing paper 8 adhesively apply | coated is sent out to the some suction roller 4, and it is sent out on the rail 6 by the some suction roller 4. As shown in FIG. When the printing paper 8 abuts on the rail 6, the feeding power by the suction roller 4 acts on the printing paper 8, and this feeding output tries to distort the printing paper 8.

On the other hand, in this example, the pair of wires 53 provided with the tension by the tension spring 54 allow the vicinity of both side ends 802 of the printing paper 8 to the suction roller 4. Pressurize. Then, the printing paper 8 can be prevented from being warped (to be in an upright state).

Subsequently, the pushing paper plate 71 pushes the printing paper 8 sent out over the rail 6 to the predetermined lamination position 702 and joins the printing paper 8 pushed out last time. At this time, as shown in FIG. 12, the pushing press plate 71 pushes out between the wire 53 and the suction roller 4, bending the printing paper 8. As shown in FIG. Thereby, the printing paper 8 can be pushed out between the wire 53 and the suction roller 4, without moving the wire 53 and the tension spring 54 especially. For this reason, when the printing paper 8 pushed out last time in the lamination | stacking position 702 and the printing paper 8 pushed out by the pushing-up press plate 71 are joined, it does not produce wrinkles etc. by curvature, etc. The printing paper 8 can be bonded together suitably.

For this reason, according to the paper-binding machine 1 of this example, bookbinding of the half-folded printing paper 8 can be performed suitably, without generating wrinkles etc.

In this example, the wire 53 and the tension applying means 54 can also be applied to the laminated bookbinding machine 1 shown in the first embodiment.
