  • Patent number: 4802570
    Abstract: A yoke-type stripper for an article stacker in which a series of paddles extending horizontally from vertically moving conveyor chains each carries an article that becomes a member of the stack. The stripper has rear and front rows of laterally spaced apart vertical bars. Carrier bars extending horizontally from vertical bars in the rear row constitute the bottom of the yoke. The paddles have fingers which support the articles and which pass downwardly between the bars to let the bottom article in the stack rest on the top edges of the carrier bars. A shuttle table is located adjacent the yoke and the table has slots into which the yoke bars can shift. The carrier bars are at a higher level than the table top when the stack is accumulating. Fluid work cylinders shift the yoke and the stack therein to the table slots while the carrier bars are kept at said higher level clear of the table so the pads are not dragged.
