A and the backward stroke B are formed in parallel to form an elongated arrangement, but the distance between the outer conveyor 4 outside the forward stroke A is narrowed so that the work operator can easily reach the field of view. It can be set as a compact arrangement | positioning thru | or a laying form. Since each take-out conveyor 4 is provided in parallel to the outside of the outward travel A of the tray conveyor 1, the take-out operation position located on the outer side of each take-out conveyor 4 is in a direction parallel to the outward travel A, Therefore, it is possible to perform a quick work processing operation.

また、前記のようにトレイコンベア１の往行程Ａの終端部に搬送されたトレイＴは、端部ローラ１６、１７上面で内側のスピンベルト１３、１４と、外側の幅寄せベルト１８との回転によって復行程Ｂ側へ搬送案内される。端部ローラ１６、１７は横方向のロール軸１５周りに回転駆動、又は回転自在であるから、端部ローラ１６、１７の支持構成が簡単でありながら、トレイＴの折返搬送を速やかに的確に行わせて、トレイＴの循環搬送を円滑に行わせることができる。 Further, as described above, the tray T conveyed to the end portion of the outward travel A of the tray conveyor 1 is rotated by the inner spin belts 13 and 14 and the outer width-adjusting belt 18 on the upper surfaces of the end rollers 16 and 17. Is guided to the backward stroke B side. Since the end rollers 16 and 17 are rotationally driven or rotatable around the roll shaft 15 in the horizontal direction, the support structure of the end rollers 16 and 17 is simple, and the folding and feeding of the tray T can be performed quickly and accurately. This allows the tray T to be circulated and transported smoothly.
