<p>PROBLEM TO BE SOLVED: To facilitate an exchange of trays by a method wherein when pellets are packed in the trays, a stage is moved in a direction X and at the same time, at the time of the exchange of the trays, the stage is rotated. SOLUTION: Pellets are picked up at a pickup position P, are freely carried at the distance in a direction Y and are packed in trays 5 by a pickup part. At this time, when the pellets are packed in the trays 5, a tray stage 24, which is freely rotatable with roughly the center of the upper surface of the tray stage as its axis C, is moved in a direction X to move the position for packing the pellets to the carrying line of the pellets, which are carried by the pickup part, and at the time of an exchange of the tray 5, the stage 24 is rotated to move the tray 5 to the exchange position. Thereby, an exchange of the trays 5 can be easily made.</p> |
