Abstract

Apparatus for supplying preselected numbers of superimposed prefabricated cardboard blanks of the type having alternating larger and smaller marginal flaps from an auxiliary magazine into the main magazine of a packing machine has a frame which carries the auxiliary magazine above the main magazine and is provided with several lugs which support the larger flaps of the lowermost blank in the auxiliary magazine. A photoelectronic detector monitors the height of the supply of blanks in the main magazine and transmits a signal when the height of the supply drops below a preselected value. This initiates pivotal movement of a pusher which is adjacent to one side of the pile of blanks in the auxiliary magazine whereby the pusher shifts a number of lowermost blanks relative to the lugs so that the lugs register with and can be bypassed by the shorter flaps of the thus released blanks which descend into the main magazine by gravity. The movements of the pusher are synchronized with the movements of an intercepting plate which is adjacent to a side of the pile of blanks in the auxiliary magazine opposite the pusher and serves to realign those blanks in the auxiliary magazine which might ha…
