Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a binding system suitably used for binding objects to be bound (work) such as cardboard.

Conventionally, as a binding device, for example, one shown in Japanese Patent Publication No. 51-30512 is known. In the prior art, for example, when binding both sides of a work, as shown in the above publication, a tandem type binding device in which a pair of binding machines including a stringing arm and a binding mechanism are juxtaposed is used. A work transfer conveyor was provided along with a carry-in conveyor on the entrance side and a carry-out conveyor on the exit side. Then, the work is present on the transfer conveyor and stopped at the bundling position, and while the work is bound, the next work is stopped on the carry-in conveyor and stands by, and is held as it is until the work is bound and finished. .

(Problems to be solved by the invention) In the conventional device, since the next work is put on standby until the binding of the previous work is completely completed, there is a limit in the binding efficiency, so that the replacement or the entrapment of the string is performed. If the operation is stopped when such a problem occurs, there is a problem that the work to be bound is accumulated and the flow of the whole line related to the work is obstructed.

An object of the present invention is to eliminate the above-mentioned problems of the prior art, and therefore to provide a binding system capable of significantly increasing the binding efficiency and thus preventing the work to be bound from accumulating. That is.

(Means for Solving the Problems) A feature of the bundling system according to the present invention is that the pair of bundling devices are vertically arranged and a transfer device that alternately feeds the loaded work to the pair of bundling devices is provided. The apparatus includes a pair of conveyors arranged at the same height as the transfer conveyors of each binding apparatus, a plurality of work placement tables that circulate through the positions of the pair of conveyors, and a pair of conveyors of the transfer apparatus. A stopper located at a position along the lower conveyor for stopping every other work carried into the lower conveyor at the rising position of the work table.
The plurality of work rests are separated from each other such that one of them is at a position of one of the pair of conveyors of the transfer device and the other is at a position of the other of the pair of conveyors. The platform is to include a pair of backing plates of the same level that sandwich the pair of conveyors of the transfer device and pass outside thereof.

(Operation of the above-mentioned means) The work carried in to this system is stopped by the stopper of the transfer device, reaches the position of the upper conveyor from the lower conveyor by the work placing table in that position, and the binding device above the conveyor. Sent to and bound there. With the movement of the work, the other work placement table reaches the position of the conveyor below the stopper. For the next work, the stopper does not stand up, so that the work passes through the lower conveyor and is sent to the lower binding device. Further, the next work is stopped by a stopper, and similarly placed on the work mounting table and moved up, and sent to the upper binding device.
