<p>PROBLEM TO BE SOLVED: To prevent the aggregation of plastic containers in a bridge state by a method in which in a space extending in the cross direction below a hopper, a spiked drum having numbers of spikes on the surface is rotated, at least one inner wall of a hopper is oscillated, its outside is coupled with an oscillator. SOLUTION: In a space 2 extending in the cross direction below a hopper 1, a spiked drum 4 having numbers of spikes on the surface is installed to be rotated by an axis 5. At least one inner wall 1a of the hopper 1 is oscillated by an upper axis 21, and its outside is coupled with an oscillator 24. The oscillator 44 is an eccentric disk 23 which is rotated by an axis 22, and the spiked drum 4 is constituted from disks which are made eccentric in the opposite directions to each other. In this way, the aggregation of waste plastic bottles 12 charged into the hopper 1 can be always disassembled to prevent clogging by the aggregation of the bottles 12 in a bridge state.</p> |
