In the commercial production of licorice bites, each about 1 inch long, a group of extruded 54-inch licorice strips are lifted by a programmable controlled robot from the discharge end of a lower conveyor and deposited at the input end of an upper conveyor which carries the strips to a cutting station. The robot hand has a lower stainless steel blade for insertion under the group of licorice strips to wedge the sticky strips from a board on which they are being carried by the lower conveyor. The robot hand includes an upper bar. The bar is moved relative to the blade after insertion of the blade under the licorice strips, thereby clamping the strips between the bar and the blade. The arm of the robot then lifts the hand and clamped group of licorice strips and deposits the front ends of the strips at the input of the upper conveyor.

Apparatus for moving strips using mechanical manipulator

In the commercial production of licorice bites, each about 1 inch long, a group of extruded 54-inch licorice strips are lifted by a programmable controlled robot from the discharge end of a lower conveyor and deposited at the input end of an upper conveyor which carries the strips to a cutting station. The robot hand has a lower stainless steel blade for insertion under the group of licorice strips to wedge the sticky strips from a board on which they are being carried by the lower conveyor. The robot hand includes an upper bar having a food-grade rubber undersurface. The bar is lowered relative to the blade after insertion of the blade under the licorice strips, thereby clamping the strips between the lowered bar and the blade. The arm of the robot then lifts the hand and clamped group of licorice strips and deposits the front ends of the strips at the input of the upper conveyor.

In licorice manufacturing equipment, a cylindrical multibladed cutter assembly for cutting licorice strips into bite length has its blades radially positioned in a cylindrical roller and its cutting edges transverse to the direction of movement of a conveyor carrying extruded licorice strips. For the purpose of preventing the severed bites of licorice from becoming wedged between the adjacent cutting blades, ejector rods are provided, one between each pair of cutting blades. Camming means cam the ejector rods radially outwardly at the circumferential position at which cutting takes place, thereby to dislodge and eject the licorice bites from the cutter.
