Abstract
A device for piling up flat workpieces especially box blanks characterized by a conveyor for transporting the box blanks in at least one stream of staggered blanks, a device for braking and separating the blanks in each stream of box blanks, a device for removing box blanks having contingent flaws from the conveyor, a piling device for forming piles of box blanks from the stream of blanks in the conveyor, a removing device for removing the piles of box blanks created in the piling device, a device for creating batches of box blanks standing on their edges from the piles and a device for transferring the piles of box blanks in an aligned fashion to the device for creating the batches. In particular the device for conveying includes a plurality of conveyors aligned one after the other in the direction of transport with the last conveyor in the direction of transport being pivotable around the drive roller and being part of the device for rejecting box blanks having contingent flaws. The drive for braking and separating includes a lower roll mounted between a pair of the conveyors coacting with the upper pressure roller which is moved into engagement to squeeze a box therebetween.
