Abstract

PURPOSE:To feed containers stacked in a container hopper of a packaging machine automatically by a method wherein a storage device is separated from a packaging machine and is made movable, and stacked containers stored in the storage device are divided by a shutter mechanism into portions, and the received stacked containers are raised and laterally moved directly above a container hopper. CONSTITUTION:Since a storage device 2 is independently movable, it is sent to a position at the end of a packaging machine 10. At that position, when a shutter plate 45 is moved by a shutter mechanism 4 to a position to match guide plates 41, 43, stacked containers (m) move further forward as a whole and sent to a position between the foremost stacked containers (m) and said guide plate 43 at the leading end. A movable block 62 and push-up plate 63 of an elevator 60 are raised by the function of a belt 64, and push up the stacked containers (m) sent between the shutter 45 and the guide plate 43 by the push-up plate 63, and are inserted in a bucket 73 standing-by above. The bucket 73 stops at a position at which the lower end of the bucket 73 matches the upper end of a hopper 102 of the packaging machine 10. When a stopper claw 74 turns clockwise and is released from the bottom of the bucket 73, the stacked containers (m) in the bucket 73 are fed in the hopper 102.
