Apparatus for transporting stacks of paper sheets to processing machines
First Claim
1. Apparatus for delivering discrete commodities to a processing machine, particularly for delivering spaced-apart stacks of paper sheets to a packing machine, comprising a first conveyor arranged to receive groups of commodities and to advance such groups in a predetermined direction along a predetermined path;
- first prime mover means for driving said first conveyor;
a gathering conveyor occupying a portion of said path and arranged to convert the commodities into a row on normally closely adjacent and/or actually abutting commodities and to advance the row in said direction, said gathering conveyor having a plurality of sections disposed one behind the other in said direction, means for individually moving said sections between first positions at a first level in which the commodities in said portion of said path are carried by said first conveyor and are out of contact with said sections and second positions at a different second level in which the commodities in said portion of said path are disengaged from said first conveyor by and rest on the respective sections, and second prime mover means for driving said sections in said direction; and
singularizing conveyor means arranged to receive successive commodities of the row from said gathering conveyor and to advance the received commodities in substantially uniformly spaced-apart positions toward the processing machine.

Abstract
Apparatus for advancing singularized stacks of paper sheets to a packing machine has an intermittently driven first conveyor which receives groups of abutting stacks at required or fixed intervals and overlaps in part with a continuously or intermittently driven gathering conveyor wherein successive groups are caused to form a continuous row. Successive foremost stacks of the row are taken over by a singularizing conveyor which moves the stacks apart and delivers them cyclically to the packing machine. The gathering conveyor has several sections which are disposed one behind the other in the direction of transport of stacks toward the singularizing conveyor and which can be lifted, individually or jointly, into engagement with stacks above them or lowered below the level of the first conveyor so that the latter can advance the stacks in a direction toward the singularizing conveyor. Detectors are provided to operate cylinder and piston units which raise or lower the sections of the gathering conveyor so that a section is lowered if it is not disposed below a stack or below a set of several stacks. The sections are lifted when the first conveyor is arrested upon completed advancement of a group into the range of the gathering conveyor.
