The blank system is a system for ordering and moving PET bottles from disorder to order. The blank falls from the hopper into the guide rail under the action of the hoist. Due to the shape of the preform itself, the tail of the preform is turned toward Upper, the head is facing downward, and sliding forward under the action of its own gravity, and some of the preforms that fail to fall into the guide rail are returned to the hopper through the recovery conveyor belt under the action of the kicking device.
