Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bookbinding device, and more particularly, to a fully automatic cover pasting device that automatically pastes a cover and a bookbinding, and more particularly to a method for gluing in this device. The present invention relates to an improvement in the means for crimping the inner cover and the cover.

(Prior Art) The present inventor has disclosed Japanese Patent Application No. 59-112259 (Showa 59-112259).
(filed on May 31, 2013), we proposed a fully automatic cover pasting device that automatically pasted the inside and cover.

The above-mentioned fully automatic cover pasting device includes a cover separating means, a cover transporting means, a center liner transferring means, a center liner gluing means, a means for crimping the cover and the inner liner, a bookbinding transfer/aligning means, and a cover transfer means in the device housing. A vertically reciprocating drive lifting means for combining the cover and the middle paper sent by the means and the middle paper transporting means and sending it to the bookbinding transfer/alignment means through the gluing means and the pressing means, and a means for controlling these drives are compactly equipped. It consists of In the fully automatic cover pasting device, the cover separation means, cover and center line transfer means, bookbinding transfer/alignment means, and push-up means are controlled according to a desired time program by a drive control means including one main motor. Driven. In addition, the lifting means in this fully automatic cover pasting device includes an insert plate, and this insert plate is inserted from below into the inner book, which is separated and transferred one by one with the spine facing up, and is also separated one by one. It is capable of reciprocating up and down so as to combine the inner cover with the transported cover and further move it up and down from this combined position through the gluing means and the crimping means to the binding transfer and alignment means.

On the other hand, the crimping means adopted in the prior invention mainly consists of a pair of pressure plates supported facing each other so as to be vertically swingable by a parallel link mechanism, and after combining the glued inside and cover, The upward movement of the pressing plate passes through the gap between the pressure plates, and the cover and the inside are crimped together by the upward movement against the downward force due to the pressure plate's own weight.

This fully automatic cover pasting device has become widely popular because of its compact structure and the ability to perform the processes from cover separation to binding and transfer fully automatically and quickly.

(Problems to be Solved by the Invention) However, the crimping means in the device of the prior invention performs crimping by forcing the combined cover and insert into the gap between the pressure plates. Therefore, the cover comes into sliding contact with the pressure plate in a state of surface contact and a state of pressure, so there is a large resistance, and thin covers such as vinyl or leather may wrinkle due to the resistance.

The present invention was made in view of the above circumstances, and in the fully automatic cover pasting device described above, the cover and the inner cover are crimped by linear pressure contact using a rotating roller, thereby reducing the resistance and making it thinner. It is an object of the present invention to provide a new fully automatic cover pasting device that does not cause wrinkles or the like even when the cover is covered with paper.

In addition, the above-mentioned alignment position 22 is a center line N glued by the gluing means 4 to the lower surface of the cover A sent from the cover transport means 2.
A pair of cover guide members 24, 24 extending from the cover separating means 1 are installed in a partitioned area directly below the crimping means 5 at the position where the sheets are combined. The cover guide member 24,
24 is a box 2 for the cover center rounding means 21;
The spacing is adjusted according to the width of the cover A using an adjustment handle 241 provided on the cover 10. A width fine adjustment member 242, 242 of a cross-section type that supports the side edge of the cover A is attached to the inner surface facing the tip of the guide member 24° 24 via adjustment screws 243. The cover sheet A transferred by the center rounding means 21 is held so as to be combined with the middle sheet N. Furthermore, strip-shaped plates 244, 244 that support the side edges of the cover A are removably attached to the lower sides of the width fine adjustment members 242, 242. The plates 244, 244 are used to prevent the cover A from loosening at the alignment position 22 when pasting a thin cover A; conversely, when pasting a thick cover A, the plates 244, 244 are used to prevent the cover A from loosening at the alignment position 22. If it exists, the cover A will be bent due to the action of the pinch rolls 56 of the crimping means 5 when the middle tension N mounted on the upper end of the middle insert plate 71 moves upward, so it must be removed. . Also.

The middle insert plate 71 moves up and down at the center of the alignment position 22, and the upper end of the middle insert plate 71, which looms up with the middle tension N mounted on it, touches the center lower surface of the cover A that has been sent above the alignment position 22. A guide roll 25° 25 for the intermediate plate is provided at a position corresponding to the alignment position 22 so as to properly match the position.

(Function) In the fully automatic cover pasting device configured as described above, the cover transport means 2 and the liner transport means 3 move forward as the drive control means 8 is driven. During this forward movement of the cover transporting means 2, the covers A separated one by one by the cover separating means 1 are transferred to the cover center rounding means 21, and the rounding means 21
The rounded cover A is aligned with the center @N at the alignment position 22
will be transferred to.

Further, at this time, the padding N supplied one by one from the padding supply means 31 is transferred to the gluing preparation position 32 via a waiting position W33. When the cover transporting means 2 and the padding transporting means 3 move back, the pushing up means 7 moves upward and pushes up the padding N at the gluing preparation position 32 in a mounted state, and the gluing means 4
Glue the outer surface of the Nakazuri N, and further push it up using means 7.
moves upward to unite the cover A and the padding N at the aligning position 22, and the crimping means 5 affixes the cover A and the padding N together to form a booklet B, which is bound by the pressing means 7. By the subsequent upward movement, the books are sent onto the binding transfer/alignment means 6. When the lifting means 7 reaches the top dead center, it quickly moves downward, and at this time, the cover transport means 2 and the middle tension transport means 3 begin to move forward,
As the transfer of the cover A and the inside N is resumed, the extrusion device 63 of the bookbinding transfer/aligning means 6 is operated in conjunction with this forward movement, and the bookbinding B on the bookbinding and aligning table 61 is pushed out in the alignment direction.

As described above, the cover sheet A sent to the alignment position 22 is combined with the inner sheet N whose outer surface is glued by the gluing means 4, and is stuck together by the pressing means 5 by the continuous upward movement of the inner insert plate 71. It is said that To explain this crimping process in more detail, the pinch roll 56.
The gap 56 is adjusted to match the thickness of the filling N to be treated. In this case, since the bookbinding transfer/aligning means 6 is rotatable around the support shaft 601, the adjustment can be easily made by rotating it and leaving the top of the crimping means 5 in an open state. Furthermore, the support frame 52 of the crimping means 5.
52 is flipped upward as shown in FIG. 4, and the spacing between the width fine adjustment members 242 and 242 is adjusted and the plates 244 and 244 are attached. Then, when the apparatus is started after the support frames 52, 52 and the bookbinding transfer/alignment means 6 are placed in the proper positions, the insert plate 71 rides on the insert N at the gluing preparation position 32. The cover sheet A moves upward, and its outer surface is glued by the gluing means 4. By the subsequent upward movement, the cover sheet A and the cover sheet N, which have been sent to the alignment position 22 by the cover sheet transport means 2, are combined, and the pinch rolls of the crimping means 5 When the combined cover A and padding N pass between 56 and 56, the cover A is folded from its center, and both are pasted together under the action of the pinch rolls 56 and 56. At this time, the cover A is pressed into line contact with the pinch rolls 56, and since each pinch roll 56 rotates on its axis, the resistance when passing through the gap is small, and extremely smooth integration is achieved. Furthermore, when the pinch rolls 56 are urged in the direction facing them by the tension springs 562, the cover A and the middle tension N move upward in the gap against this elasticity, so that the pressing force is reduced. is large, so that the above-mentioned attachment and integration can be carried out more reliably, and even if there is some variation in the thickness of the inner tension N, it is absorbed by the elasticity of the springs 562, and smooth attachment and integration can be achieved.

This series of operations is driven by one main motor 81 of the drive control means 8 according to a desired time program, and a booklet B, in which the cover A and the booklet N are pasted together, is automatically created on the bookbinding alignment table 61. They are arranged in a straight line. As in the embodiment, a compression coil spring 85 is attached to a swinging lever 83 for reciprocating the cover transporting means 2 and a booklet transporting means 3, and a lifting swinging lever 84 for reciprocating the lifting means 7 up and down. If a foreign object is caught during operation, or if a worker's hand is caught in the machine, the shock will be alleviated, and damage to the equipment and injury to the worker can be prevented. .

(Effects of the invention) As mentioned above, in the fully automatic cover pasting device of the present invention, 1
The pressure bonding for attaching and integrating the cover and the inner cover is done by pinch rolls that press in line contact, so the resistance is small and even thin covers can be bonded uniformly without wrinkles. I can do it. What's more, this pinch roll's facing distance can be adjusted with an adjustment screw, so
Adjustment can be easily made according to the thickness of the filling. Furthermore, since the support frame is pivotally supported on the housing of the device so that it can move up and down, by flipping it up, it is extremely easy to adjust each member in the alignment position directly below the crimping means. There is also the added advantage that it can be done.
