PURPOSE:To obtain a stably separating operation of piled parts through a single driving system by providing a guide plate, on which a groove cam of a hysteresis path, whose advancing route is different from the return route, is formed, and connecting separating nibs to a cam follower, which moves along said groove cam. CONSTITUTION:When an elevating table 7 is raised by means of a cylinder 2 after a number of trays 6 are placed on a placing table 4, the cam follower 14 of a guide member 13 is restricted for its direction at the bottom end part of a shutter 17 and, therefore, is raised along the advancing route of a groove cam 16. At this time, more than one set of separating nib 10 is raised while being tuned, and their end parts are inserted between the collar parts 6a of the trays 6, with a group of the trays including the tray 6 at the second stage from the bottom being pushed up. Thereby, the tray 6 at the bottom stage is separated, and is made slide to be supplied in the second process. After that, the elevating table 7 is lowered and, in this case, the cam follower 14 is lowered along the return route of the groove cam 16, unloading the group of trays onto the placing table 4. |
