Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, stacks a large number of voucher sheets into one book, forms such as various forms, or a large number of booklets such as books, and stacks them from the bottom. The present invention relates to a separating / conveying device that sequentially picks up and conveys one by one.

[0002]

2. Description of the Related Art In binding a form A as shown in FIG. 11, first, the sheets are collated and superposed,
As shown in FIG. 12 (a), temporary binding is performed by gluing the back A1 and then, for example, the actual fair 3-15.
Using a spine pasting machine as described in Japanese Patent No. 328, a spine tape B is glued to the back portion A1 of the form A as shown in FIG. 12 (a).

The form A is conveyed in such a posture that the back portion A1 extends in the conveying direction, and as shown by an arrow C in FIG. 12 (b), a back tape B is guided by a guide body (not shown).
As a result, as the form A is conveyed, the back part A1 is gradually wrapped and adhered. When transporting the temporarily bound forms A to the spine sticking machine, a large number of them are superposed on the table, and they are separated one by one in order from the bottom, and are transported. Conventionally, the structure has been as shown in FIG. 13 (a) or (b).

That is, in the structure shown in FIG. 13 (a), a groove extending along the transport direction is formed in a table 40 on which the stacked forms A are placed, and an endless chain 41 is rotatably arranged in the groove. , This endless chain 41
In addition, a claw 42 that hooks on the rear surface of the lowest form A is provided,
Further, a stopper 43 is provided on the table 40 to stop the second or more forms A, so that the claw 42 of the endless chain 41 pulls out only one of the lowest forms A and puts it on the backing machine. It is adapted to be transferred to the conveyor 44.

In addition, FIG. 13B shows a table 4
The feed roller 45 is rotatably arranged below 0, the roller 45 is brought into contact with the lower surface of the lowermost form A through the groove formed in the table 40, and the lowermost form A is rotated by the rotation of the roller 45.
It was designed so that only one copy was taken out.

[0006]

However, as shown in FIG. 13 (a).
In the means for pulling out the form A by the claw 42 provided on the endless chain 41 as described above, the claw 42 hits a narrow area on the rear surface of the form A, so that a dent-like scratch is likely to be formed on the part hit by the claw 42 was there. Further, since the protrusion size of the claw 42 must be set in accordance with the thickness dimension of the thinnest form A, if the thickness of the form A is large, the claw 42 may not be sufficiently caught and may not be pulled out. There was also the problem of saying that there was.

Further, since the orbiting time of the pawl 42 in the endless chain 41 is constant, the take-out interval is different when the length of the form A is different. Therefore, when the length of the form A is short, the take-out interval is long. It was also a problem that time loss occurred. On the other hand, FIG. 13 (a)
With the means for taking out using the roller 45 as described above, the form A can be taken out at a constant interval regardless of the length, but since the contact area between the roller 45 and the form A is small, the lower surface of the form A ( There is a possibility that a trace of the roller 45 hitting the front cover or the back cover may remain. In addition, the roller 45 is used for the form A.
Since it is applied to the lower surface of the sheet A, if the number of remaining sheets of the form A is reduced, there is a problem that the friction between the roller 45 and the form A is reduced and there is a risk of feeding failure.

An object of the present invention is to provide a separating and conveying apparatus which solves these problems.

[0009]

In order to achieve this object, the present invention provides a "separating / conveying device in which a large number of vertically stacked booklets are taken out in order from the lowermost stage and fed out. An endless belt for transporting booklets is circulated freely on a table for supporting, and a stopper for stopping the second or more booklets among the stacked booklets is vertically moved above the table. It is arranged so as to extend in the direction ".

In the present invention, the "booklets" are not limited to the above-mentioned forms and books, but include articles having a certain thickness.

[0011]

With this structure, since only one booklet can be pulled out from the lower side of the stopper, the booklets stacked on the table are fed one by one as the endless belt goes around. Be done. In this case, the booklet is in close contact with the endless belt over its entire length, and the booklet can be supported in a large area by the endless belt, so that the booklet is not scratched when it is fed out one by one. When one booklet comes out of the stopper, the next booklet is conveyed by the endless belt at the same time. Therefore, the booklets can be efficiently separated and conveyed regardless of their length.

Further, since the booklets are placed and conveyed on the upper surface of the endless belt, the friction between the endless belt and the booklets is significantly reduced even if the number of booklets on the table is reduced. Nothing, and therefore
The last one can be accurately conveyed without causing a feeding failure. By the way, as the bottommost booklet comes out of the stopper, the second-stage booklet sequentially contacts the endless belt from the rear end to the front end. In this case, if the length of the booklet becomes longer than a certain amount, the friction between the rear portion of the second-stage booklet and the endless belt becomes excessively large, and the second-stage booklet is separated during the separation of the second-stage booklet. There is a possibility that the rear end of the booklet may be caught in the endless belt or the paper may be wrinkled.

On the other hand, according to the second aspect of the invention, the rear portion of the second-stage booklet is floated from the endless belt due to the existence of the auxiliary stand, and the rear portion of the second-stage booklet is endless. Since it is possible to prevent contact with the belt, it is possible to reliably prevent the rear part of the booklet from being caught in the endless belt or wrinkled, and moreover, the guide that the upper surface of the auxiliary stand is tilted forward. Due to the action, there is an advantage that the form can be separated and conveyed smoothly.

Further, for example, when the back tape is stuck to the above-mentioned form by the back sticking machine, not only when the separate carrying device automatically carries the forms one by one to the back sticking machine, but also the separate carrying device is removed. In some cases, the forms may be manually fed to the spine pasting machine one by one, and thus the separating / conveying device may be detachably attached to a succeeding device such as the spine pasting machine. With such a configuration, the separation / conveyance device can be accurately positioned with respect to the subsequent device by fitting the recesses and the protrusions, and thus there is an advantage that the separation / conveyance device can be attached / detached efficiently and accurately.

Further, when the separating / conveying device is attached to a succeeding device such as a spine sticking machine and the endless belt of the separating / conveying device is transferred to the conveyor of the succeeding device, the endless belt can be constructed by constructing as in claim 4. Even if the booklets are continuously fed around at a constant speed and a constant speed is provided between the front and rear booklets on the conveyor of the subsequent device due to the speed difference between the endless belt and the conveyor, There is the advantage that the transport of the booklets with a distance to the subsequent device can be achieved with a very simple structure.
