However, in the above-mentioned prior art, in the case of relatively small-sized works, after the two works are simultaneously conveyed to the sorting position via the carry-out conveyor, these works are different from each other. It is necessary to move the workpiece in the direction, and a dedicated sorting means different from the sorting means for sorting large workpieces one by one is used. For this reason, various sorting means must be prepared according to the size of the work, the equipment cost rises, and the preparation work such as replacement of the sorting means takes a lot of trouble and time. Has been done.

The present invention is intended to solve this type of problem, and it is not necessary to prepare a dedicated sorting means or the like for the molded products having different sizes, and the molded products having different sizes are the same. An object of the present invention is to provide a method for automatically distributing molded articles that can be efficiently and easily distributed by a structure.

[0005]

In order to achieve the above-mentioned object, the present invention conveys a molded product delivered from a press machine to a pair of distribution positions via a pair of delivery conveyors,
An automatic distribution method of automatically distributing the molded products to the left and right through a pair of pushing means provided at the distribution position, wherein the molded products carried out from the press machine can be individually carried by each carry-out conveyor. In the case of dimensions, a step of individually conveying the molded product to the pair of distribution positions by respective carry-out conveyors, and after the respective molded products are conveyed to the pair of distribution positions, the pair of extrusion means are A step of displacing each of the molded products to the left and right by moving in different directions, while the molded product carried out from the press is larger than a size that can be individually conveyed by each carry-out conveyor, Integrally transporting the molded product of (1) to the pair of distribution positions by the pair of carry-out conveyors, and transporting the single molded product to the pair of distribution positions. After that, a step of integrally moving the pair of pushing means arranged in advance at one of the distribution positions toward the other distribution position to distribute the single molded product leftward or rightward, It is characterized by being provided.

[0006]

In the above-described method for automatically distributing molded products according to the present invention, when a relatively small-sized molded product is conveyed to each distribution position by each carry-out conveyor, the pair of pushing means move in different directions. The respective molded products are distributed to the left and right. On the other hand, in the case of a molded product having a relatively large size, a single molded product is integrally conveyed by a pair of carry-out conveyors and is integrally arranged at a pair of distribution positions. Then, the pair of pushing means moves integrally from one distribution position to the other distribution position, and the single molded product is distributed leftward or rightward. Therefore, molded products having different sizes can be easily distributed through the same pushing means, and the structure can be simplified.
