Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamper device for a bookbinding machine, and in particular, a bookbinding machine that holds and holds the body from both sides so that each process necessary for bookbinding can be performed on the body that is bound into one book. This relates to a clamper apparatus.

In a bookbinding machine that glues the back of a stack of papers that are bound into a single book and attaches a cover to the booklet, and then performs wireless binding, the body is sandwiched between a pair of plates called clampers. In this state, it is moved to each processing step necessary for bookbinding.
An example (first example) in the background art of the clamper device in such a bookbinding machine is shown in FIGS.

  The clamper device of the bookbinding machine has a structure in which the body 100x is sandwiched between a fixed clamp plate 251 and a movable clamp plate 252, and the movable clamp plate 252 is moved by a clamp moving bearing 254 guided and held by a shaft 253. Thus, the main body 100x placed so that the back portion is aligned by the alignment receiving base 255 is sandwiched between the fixed clamp plate 251 and the movable clamp plate 252.

As described above, when the body 100x is sandwiched between the clampers (251, 252), the end of the body 100x is aligned and the back portion is horizontally aligned. The parts may be misaligned or the orientation of the body may change.
In each processing step necessary for bookbinding, for example, milling, gluing, service pasting, etc., the body is clamped with a strong force using a spring so that the body does not vibrate or slip. There is an example of doing so.
However, if it is sandwiched by this strong force, the body that has been displaced cannot be corrected.
If they were misaligned, it was time consuming because the clampers had to be opened and realigned and then pinched again.
Moreover, even if it pinches again, the shift | offset | difference will arise similarly by the impact at the time of the pinching.

Therefore, an auxiliary clamp plate is provided inside a pair of clamp plates, and the auxiliary clamp plate temporarily sandwiches the body with a relatively weak pressure before sandwiching between the pair of clamp plates, and then sandwiches the main body. A device has been proposed.
A second example of such background art is shown in FIGS. 11 (a) and 11 (b).

  In this second example, the body 100y is sandwiched between the fixed clamp plate 303 that is in surface contact with one surface of the body 100y and the guide plate 312 that is in surface contact with the other surface. However, the guide plate 312 is pressed against the movable clamp plate 305 via the coil spring 313 and is brought into pressure contact with the other surface of the main body 100y so as to be in a pinched state.

The movable clamp plate 305 has a structure in which the rotational force of the cam 311 is transmitted through an intermediate transmission mechanism and the guide plate 312 is pressed by the coil spring 313.
Further, the back portion of the main body 100y is arranged in contact with the platen 301 (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 61-135671 (FIGS. 1 and 2)

  In the second example in the background art described above, a guide plate 312 as an auxiliary clamp plate is provided inside a pair of clamp plates (fixed clamp plate 303 and movable clamp plate 305), and this guide plate 312 is connected to a coil spring. The guide plate 312 is pressed against the other surface of the main body 100y by being pressed by the movable clamp plate 305 through 313, and is in a main clamp state. In addition, the guide plate 312 can be brought into surface contact with the other surface of the main body 100y by the weak force of the coil spring 313 so that the guide plate 312 is temporarily sandwiched by the relatively weak force. Even if the guide plate 312 is pressed with a relatively weak force, as long as the guide plate 312 is in surface contact with the body even if it is a weak force, the book Disturbance of the 100y is difficult to fix, thin and weak hips aligned hard paper, with respect to this body must release the pressure that is once clamped, there is a problem in that.

  In this example, the movable clamp plate 305 is moved while measuring the distance between the movable clamp plate 305 and the body 100y, and when the predetermined distance is detected, the movable clamp plate 305 is stopped and temporarily moved. Since it is necessary to be in a pinched state, there is a problem in that the paper and the body are thin due to insufficient pressure for temporary pinching and the paper and the body are thin and weak.

  In view of the problems in the background art described above, the object of the present invention is to easily correct the disturbance even on thin, weak paper and the body, and in the temporary pinching state and the main pinching state.
