ABSTRACT:
Apparatus for transferring articles such as glass containers from a first conveyor, on which the containers are traveling generally horizontally in line one after another, on to a second conveyor extending generally at right angles to the first conveyor from one side of the first conveyor. The apparatus is operable in cycles to transfer on each cycle a group of articles from the first to the second conveyor with the articles in the group extending in a row transversely of the second conveyor. The apparatus includes a support, a first carriage on the support movable generally parallel to the second conveyor, a second carriage on the first carriage movable with respect to the first carriage generally parallel to the first conveyor, and a third carriage on the second carriage movable vertically with respect to the first and second carriages. The third carriage carries a pusher bar. The carriages are driven by separate motors under the control of a programmable controller which operates the motors during each cycle of the machine to drive the carriages to cause the pusher bar to transfer a group of articles from the first conveyor on to the second conveyor. A software system allows the desired motion to be plotted along each axis as a motion profile formed as a velocity versus time plot superimposed on the plots for the other axes. Before the motion plots are downloaded for use in operating the stacker, the stacker movements they represent are verified by a pictorial simulation of a stacker bar operating cycle in a video monitor.
