The transfer section is equipped with a chain drive device having a large number of transfer claws that move intermittently at predetermined intervals in a groove provided in the same direction as the horizontal transfer surface, and above the transfer section there is a tip position of the transfer section. a temporary paper-receiving fork that protrudes to the same height or a lower position to receive the form body, and retreats to a position facing the conveying section to drop and stack the form body onto the conveying section; The fork tip side has a temporary paper receiving part that moves up and down with a predetermined stroke and can move horizontally or tilted, and a paper receiving part on both sides of the paper receiving part on the upstream and downstream sides of the transfer part in the form transfer direction, and below the form body. The present invention provides a collating machine characterized by having a suction device provided on the side or top side for supplying paper sheets such as front and back covers, thereby solving the problems of the prior art.

[Effect]

In the present invention, a suction device located upstream of the temporary paper receiving section sends the cover etc. to the transfer section, and this cover etc. is transferred to the temporary paper receiving section side by a chain drive device, and is sent from the collator as needed. For example, the first
The temporary paper receiver receives the form body, the cover sheet, etc. is transferred under the temporary paper receiver, and the temporary paper receiver drops the form body onto the cover sheet, etc.,
After that, the blockage state of the supply path of the form body from the collator to the transfer unit is released, and a predetermined number of form bodies are sent from the collator side onto the first form body,
Then, the stacked form body is sent by a chain drive device to a suction device located on the downstream side of the temporary paper receiving section, and the back cover etc. are placed thereon.

〔Example〕

As shown in the plan view of Fig. 1, the collating machine of the present invention includes a transfer section A, paper feed sections _B1 , _B2 for covers etc., and a temporary section for temporarily receiving the first set of form bodies. It consists of a paper receiving section C, a conveyor section D, and a collator E that continuously transports the form body.

The transfer section A includes a horizontal transfer surface having a transfer guide wall that regulates the paper position, and a large number of transfer claws that are regulated and move intermittently at predetermined intervals through grooves provided in the transfer direction of the horizontal transfer surface. When collating documents, the back cover is first fed to the above-mentioned transfer section A by the paper feed section _B1 , and then the transfer claw moves the back cover to the next paper feeding position, that is, the collator. It is transported to the unloading side position of the transport section E and stopped. Next, the collator E feeds the required set of form bodies (for example, 20 sets of 6 slips, etc.) onto the back cover one set at a time. However, for at least the first set, the temporary paper receiving fork of the temporary paper receiving section C provided at a position opposite to the collator E moves forward to temporarily receive the paper, and at the same time as the back cover is transferred to the position of the collator E, Paper is fed from the paper receiving fork.

Next, the transport claw transports the set of several dozen sets of the back cover and the form body to the next paper feeding position, that is, paper feeding section _B2 , and stops there. Next, the front cover is fed from the paper feed section _B2 , and the front cover, several dozen sets of form bodies, and the back cover are collated in this order to obtain one book of forms. In addition to the paper feed sections B ₁ and B ₂ for the front and back covers, a paper feed section for inserting instructions, blotting paper, etc. may be provided as necessary.

In the above explanation, when paper feed section _B1 operates, the other paper feed sections also operate at the same time, and together with the operation of temporary paper receiving section C and transfer section A, collation is performed continuously and efficiently. It is something.

Next, the configuration of each part will be explained.

Transfer section A is located at the distal end of the conveyance section of collator E, and is a device that moves the paper in a direction perpendicular to collator E. Figure 2 is a side view of Figure 1, and Figure 3 is a side view of transfer unit A. FIG. 3 is an explanatory diagram illustrating the relationship between main parts and paper feed section _B1 . This transfer section A includes a frame 1, horizontal transfer surfaces 6, 6', 6'', transfer claws 3, 3' that move in grooves 8 provided along the horizontal transfer surfaces,
