DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookbinding machine for receiving a body and a cover in the best condition without losing a state in which a cover is attached to the body and forming the back of the book, and moving the book reasonably. It concerns the device.

[0002]

2. Description of the Related Art Conventionally, as a drop transfer device of this type, a bookbinding machine uses a device using an inclined feed conveyor 26 with respect to a clamp 27 as shown in FIGS. There has been an apparatus that uses a vertically moving conveyor unit 26a that moves a belt conveyor attached and lowered up and down.

[0003]

However, the former, FIG.
In the case of the inclined feed conveyor 26 of (a) and (b), a long place and space are required to move downward while moving forward. In the case of the latter, FIG. 4, although the length was slightly shortened by the vertical movement of the conveyor unit 26a, a distance was still required. In addition, the belt speed and the vertical movement are restricted by the relationship between the speed at which the clamp 27 is released and conveyed forward and the speed at which the clamp 27 moves forward. Could not be in the best condition. According to the present invention, by moving the conveyor unit in a fan shape, the body and the cover are received closer to the clamp, and the body and the cover are separated from the clamp in a direction in which they move in the same traveling direction as the clamp and escape downward. It is possible,
Also, by rotating the belt, it can be moved forward at an arbitrary speed and transported on a conveyor, so that it can be received and transported without breaking the state where the cover is attached to the main body and the spine of the book is formed. The purpose is to do.

[0004]

SUMMARY OF THE INVENTION The gist of the present invention is that the upper end of a swingable front and rear link having a lower end pivotally connected to a machine frame can be moved in the clamp advancing direction by driving a motor. Each of the conveyor units in which the conveyor belt is mounted is pivotally attached to the front and rear portions thereof and connected to a driving shaft-driven swinging swinging device. The swinging swinging device synthesizes the swinging back-and-forth and fan-shaped vertical movements on the conveyor unit. The bookbinding machine is characterized in that the body and the cover are separated from the upper clamp, dropped on the conveyor belt of the conveyor unit, sent forward, and transferred to the front conveyor system ahead. It is a transport device. Next, embodiments of the present invention will be described with reference to the drawings.

[0005]

1, an upper end of a swingable front and rear link 8, 9 having a lower end pivotally attached to a machine frame 1, 10 and 12, respectively, is moved by a motor 4 in the traveling direction of the clamp 24. Conveyor unit 2 with conveyor belt 3 inside
Are connected to a swinging device M driven by a driving shaft 18 to be described later, and the swinging device M causes the conveyor unit 2 to swing forward and backward and to move up and down in a fan shape. The body and the cover 25 are separated by the upper clamp 24 and dropped on the conveyor belt 3 of the conveyor unit 2 so that the body and the cover 25 are separated from each other.
Is transported forward to a front conveyor system 23 in front of the vehicle. Next, reference numeral 15 denotes an eccentric ring in which an eccentric sheave 17 in which a driving shaft 18 is disposed at an eccentric position is loosely fitted in a strap 16, and a tip of a rod 19 of the eccentric ring is pivotally connected by a pivot shaft 21. It is pivotally connected to one end of the lever 20. A connecting rod 22 is pivotally connected between the other end of the link lever 20 and the tip of the arm rod 14 integrated with the link 8. In addition, 5 is a guide, and 6 and 7 are brackets. Further, in the embodiment shown in FIG. 1, the lengths A and B of the links 8 and 9 and the pitches P and R of the upper and lower pivot portions of the links 8 and 9 are different from each other (A> B and P <R in FIG. 2A). ), But the lengths A and B of the links 8 and 9 are different.
The pitch dimensions P, R of the upper and lower pivot portions of the links 8, 9 are the same. (A> B, P = R in FIG. 2B), link 8,
9 have the same length dimensions A and B and the pitch dimensions P and R of the upper and lower pivoting portions of the links 8 and 9 (A = B, C in FIG. 2).
P = R), the lengths A and B of the links 8 and 9 are the same, and the pitches P and P of the upper and lower pivots of the links 8 and 9 are the same.
R different (A = B, P <R in FIG. 2) can be selectively used.

[0006]

According to the present invention, by moving the conveyor unit in a fan shape, the main body and the cover are received closer to the clamp, and the main body and the cover are moved in the same traveling direction as the clamp and escaping downward. Can be separated. By rotating the conveyor belt, the belt can be moved forward at an arbitrary speed and transferred onto the conveyor, so that the state in which the cover is attached to the text can be received and transferred without breaking. In the device of the present invention, the front link is moved upward from the ordinary fan-shaped movement when receiving the text and the cover with the clamp released because the length dimension of the front and rear links is changed and the mounting pitch dimension is changed. Will receive the text and cover in a better way. In addition, when the conveyor unit that moves up and down in a fan shape by a crank that is synchronized with the clamp driven by the driving shaft moves downward from the upper end, the body and cover sandwiched between the clamps are released on the conveyor unit. The body and cover dropped on the belt of the conveyor unit move in the same traveling direction as the clamp by the rotation of the belt, and at the same time, the conveyor unit moves downward in the fan-shaped traveling direction by the clamp and link lever, The body and cover are separated from the clamp and moved forward and downward while moving the body and cover so that they can be transported to the front conveyor system near the lower end.
