Stacks of superimposed paper sheets are formed from a succession of layers each of which contains a given number of groups of sheets. One or more layers which contain a first number of groups can be followed by one or more layers containing a different second number of groups so that a stack can contain layers which, in turn, contain different numbers of groups and hence different numbers of sheets. The number of sheets in each stack and in each layer is a whole multiple of the number of sheets in a group. If the average number of sheets in a series of successive stacks is to deviate from a whole multiple of the number of sheets in a group, successive stacks contain different numbers of sheets; each such number is a whole multiple of the number of sheets in a group but the total number of sheets in the series of stacks divided by the number of stacks which form the series can deviate from such whole multiple.

Method of accumulating stacks of paper sheets or the like

Apparatus for accumulating stacks of paper sheets or the like

Apparatus for accumulating discrete stacks of superimposed note books has a feeding conveyor which delivers note books seriatim into each of a battery of receptacles forming a row which extends transversely of the direction of feed of note books. Each receptacle has a composite bottom wall with two elongated horizontal carriers which are movable sideways toward and away from each other to constitute a platform for an oncoming note book in those positions in which they are closer to each other and to provide an opening for gravitational descent of a note book onto a stacking table therebelow in those positions in which they are more distant from each other. The carriers are parallel to the direction of feed of note books into the respective receptacles, one carrier of each bottom wall is connected to a first reciprocable support, and the other carrier of each bottom wall is connected to a second reciprocable support. The supports form part of a parallel motion mechanism which is actuatable by a double-acting pneumatic cylinder and piston unit to move the carriers of each bottom wall toward and away from each other. The cylinder and piston unit is actuated in response to signals transmitted by a photocell which monitors the feed of note books to the receptacles. The stacking station accommodates a vertically movable table which supports the growing stacks and is caused to descend upon accumulation of complete stacks to thereby deposit the fully grown stacks onto the upper reaches of belts forming part of a take-off conveyor.
