Abstract

The figure illustrates a system for unloading cushions, such as molded polystyrene packaging cushions, from a press, conveying them with a trolley that holds the cushions in place by a suction, transporting the removed cushions by way of an air conveyor, and metering and positioning the cushions to receive the product to be protected at a packaging station.

System for Unloading, Conveying And Positioning Product Cushions

The figure illustrates a system for unloading cushions, such as molded polystyrene packaging cushions, from a press, conveying them with a trolley that holds the cushions in place by a suction, transporting the removed cushions by way of an air conveyor, and metering and positioning the cushions to receive the product to be protected at a packaging station.

Referring to the Figure, the cushions are formed in a two-part mold comprising halves 1 and 2. After being formed, halves of the mold separate and a trolley 3 moves into position between the mold halves. A bellows or some other mechanism moves the trolley face 4 into contact with the surfaces of the cushions 5. A partial vacuum is drawn on the trolley face 4 to grip the cushions as they are ejected from the mold, and holds them in place as the trolley moves along track 6 to a horizontal position over conveyors 8. After being positioned, the partial vacuum is released, and the cushions are allowed to drop onto the conveyors 8 for transport to another location. The trolley 3 then returns to repeat the cycle.

The cushions are transported, such as by an air conveyor, to a vertical chute
10. A metering mechanism 11 includes a pivoted arm 12 connected to a block 13 at one end. The opposite end rests on block 14, which is connected to a second pivoted arm 15. The blocks 13 and 14 are alternately moved into and out of the cushion path to meter the cushio...
