Furthermore, after the article (C) enters the belt conveyor (1a) of the yawing conveyor (1), the belt conveyor (1a) is rotated to move the entry side thereof to the continuous transfer arm (2).
When the belt conveyor (1a) is operated in the reverse direction and transferred from the entrance side to the continuous transfer arm (2), the article (C) can be moved forward and backward by 180 degrees. It can also be reversed and carried out to a subsequent process.

In this case, the sorting element includes classification of a non-defective product or a defective product, classification by reading an identification mark such as a bar code attached to the surface of the article (C), and the like, and upstream of the continuous transfer arm (2). It is also conceivable that the end is connected to the turntable (1c) of the yawing conveyor (1) and the continuous transfer arm (2) is also rotated in the horizontal direction in conjunction with the rotation of the yawing conveyor (1).

In the above-described embodiment, the case where the conveyor (A) in the previous process and the conveyor (B 1 ) (B 2 ) (B) in the subsequent process are connected is shown, but the present invention is not limited to this. The same applies to a pusher that moves toward the yawing conveyor (1) or another component such as a pusher that is connected to the downstream end of the continuous transfer arm (2) in a subsequent process.

<Structure of the Invention> Since the present invention has the above structure, it has the following advantages.

When the articles are received on the yawing conveyor from the conveyor or the pusher in the previous process, the yawing conveyor rotates a predetermined angle in the horizontal direction as necessary while transferring the articles downstream with the operation of the yawing conveyor, and is aligned with the continuous transfer arm. By doing so, the article is changed in direction and transferred onto the continuous transport arm, and the article is carried out to a subsequent process with the operation of the continuous transport arm, so that the article can be continuously operated only in the downstream direction.

従って、物品1個毎に返り工程がありしかも間欠的に
作動する従来のものに比べて、返り工程がなく物品1個
当りの処理時間を短くでき、結果的に高速処理が可能と

Therefore, as compared with the conventional one which has a return step for each article and operates intermittently, there is no return step and the processing time per article can be shortened, resulting in high-speed processing.

When the specification of the article changes and the positional relationship of the post-process to the pre-process changes, the continuous transfer arm is rotated in the horizontal direction around the center of the yawing conveyor, and the downstream end of the continuous transfer arm is extended and retracted. Since it is moved up and down to make it close to the subsequent process, and the rotation angle of the yawing conveyor is controlled again, it is possible to connect the preceding and succeeding processes without minimizing the operation control and greatly changing this.

Therefore, it is inexpensive compared with the conventional system that automatically controls all operations, and requires less adjustment work than the conventional system that requires the entire program to be newly set every time the specification of an article changes. It can be easily performed by people without specialized knowledge.

If the articles conveyed to the downstream end of the continuous transfer arm are sandwiched by the delivery hand and the articles are carried out to a predetermined position in the subsequent process, the positional accuracy in the subsequent process can be improved.

Therefore, even when the post-process requires a positional accuracy such as a bucket conveyor, the articles can be reliably transferred.
