PURPOSE:To enhance efficiency of stacking, by raising containers on a self-running pallet table, stacking them after passing a stocker opening part by means of detention by a one-direction swingable detent arm one after another, and then taking out those sunk one after another through release of the arm. CONSTITUTION:When a table 12 is raised according to a vertical motion signal after a self-running pallet is stopped in any desired position, a container 1 passes an opening 42, and a detent arm 5 comes in contact with a detained part 1a to make upward swing. When this contact is put free, return to the original position is made by the own weight. After this return, the arm 5 retains the container 1, and containers are stacked with respect to a container stocker 2. In the takeout process, the table 12 is moved upward, at a specific stroke after shifting the pallet to the desired position, and the arm 5 is moved by a signal transmitter to a position where engagement with the above-mentioned detained part 1a is no more possible. Then containers are moved downward by the sinking table 12, and when the undermost container 1 is passed from the opening 42, signal emission from the transmitter will be shut off to actuate return of the arm 5 to its original position. Thereby the efficiency of stacking can be enhanced. |
