Abstract

PURPOSE: To conduct reception and transfer without collapsing the state that a cover is sticked to a text and the backbone of a book is formed. CONSTITUTION: A conveyor unit 2 is moved and rotated by combining the longitudinal oscillation and fan like vertical movement, a text and a cover are separated by an upper clamp 24, dropped on the conveyor 3 of the unit 2, fed forward and transferred to a forward front conveyor system 23. Accordingly, the unit is moved in the fan shape, the text and the cover are approached by a clamp, received, and can be separately by the clamp in the downward releasing direction while moving in the same advancing direction as the clamp. Since they are moved forward at an arbitrary speed by rotating a conveyor belt and transferred to the conveyor, they can be received and transferred without collapsing the state that the cover is sticked to the text.

Description

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-conveying device of this kind, a bookbinding machine, a device using an inclined feed conveyor 26 for a clamp 27 as shown in FIGS. There is a device that uses a vertical movement conveyor unit 26a that moves a belt conveyor that has been installed up and down.

[0003]

However, the former, FIG.
In the case of the inclined feed conveyor 26 of A and B, a long distance place and space are required to move downward while moving forward. In the latter case of FIG. 4, the conveyor unit 26a moved up and down, which shortened the length a little, but still required a distance. In addition, because the belt speed and vertical movement are limited due to the relationship between the speed of moving forward and the speed of being released from the clamp 27, and the speed at which the clamp 27 moves forward, the main body and the cover are received and conveyed. It is something that 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, the present invention will be described with reference to the drawings with reference to the following embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, first, the upper ends of swingable and swingable front and rear links 8 and 9 each having a lower end pivotally attached to a machine frame 1 10 and 12 are moved by a motor 4 in a moving direction of a clamp 24. Conveyor unit 2 equipped with a conveyor belt 3
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 forwarded to the front conveyor system 23 in the front. Next, 15 is an eccentric ring in which an eccentric sheave 17 in which a driving shaft 18 is arranged in an eccentric position is loosely fitted in a strap 16, and a tip of a rod 19 thereof is a link pivotally mounted 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.
Different Rs (A = B, P <R in FIG. 2D) 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.
