ABSTRACT:
A Full Depth Uncaser for automatically removing bottles from a case having a depth substantially equal to the bottle height, and delivering the bottles to a delivery conveyor. The Uncaser utilizes a system of individual grippers arranged in the general pattern of the bottles in the cases, with the various rows of grippers supported by continuous chains at each side of a gripper assembly. Each individual gripper utilizes an over-center toggle mechanism held to the open position by the toggle, and triggerable by the contact of the center member with the top of a bottle to allow a spring to cause the gripper to close on the neck of the bottle. Bottles are released onto the delivery conveyor by depression of the center member at that point to reset the over-center mechanism. Provisions for synchronizing the cases with the gripper motion as well as other features and improvements for such equipment are disclosed.
