It assumes a standby position with the top of the body protruding from the top. Container gripping (4) Mechanism (in the old version, the four drums (C) pushed upward in the manner described above were gripped by the fully blind gripping anim (10) with gripping claws at the tips), and then The four drums (9) are given simultaneous lifting action, and are a type of chuck or lock structure. Therefore, the container gripping mechanism (H) is placed relative to the drum can (C) so that it can be moved along the path, and is mounted to be vertically movable with respect to the housing (8,). The shaft (14) and the lower end of the shaft (14). It has a set of four gripping arms (1O) which are attached so as to be openable and closable, and a frame (, 9) that supports a set of four shafts (14) at predetermined intervals.

Above, the four axes (14) are 1. Prior to lifting, the frame (9) by the drum and can transfer lane (16) closes the gripping arm (10) and moves the four drums and cans onto its upper end. (as if holding it in place)
! has been completed. As a forming member of such a container gripping mechanism, gripping arms (,1Q,,) are provided in the housing (8).
The four shafts ( 14
) is incorporated with a gripping arm opening/closing device consisting of a pressure spring (not shown), a guide groove, a hydraulic cylinder mechanism, etc., which are interlocked with the vertical movement of the handle. On the other hand, in the frame (9), a container gripping mechanism (H) is attached to a drum (

Therefore, the roller (4) attached to the tip of the link (3)
is guided by the guide groove (4) and moves toward the center (0) of the arrangement of the drums (C), thereby pinching the arrangement interval of the four drums <C> held by the gripping arms (10). Thereafter, the apparatus of the present invention is transported onto the drum transport conveyor (17) by the drum transport lane (16), and the frame (9) is lowered as shown by the arrow (B), and the separately supplied pallet ( 18) Lower the drum (C) onto the top. Thereafter, the gripping arm opening/closing device is restarted, and the gripping arm (10) releases the drum can (C) from its gripping state. Therefore, four drums (C) are placed on the pallet (1B) with an arrangement interval in between, and these drums are installed on the drum transport conveyor (17) and at the end of the conveyor (17). The lid (19) (8) assumes a posture in preparation for transport to a storage room (not shown). At this time, the device of the present invention returns the link mechanisms (2) and (3) to their original positions by reversing the drive device (D) (indicated by the arrow (A)), and moves the gripping arm (10) to the second position. It is maintained in the open state shown by the solid line in the figure. The device of the present invention is then transported back to the standby position above the drum head jack (12) by the drum transfer lane (16), and is transferred to the following drum (C) according to the operating procedure described above. Repeat the array interval adjustment operation.
