发明名称 Apparatus for destacking at least two stacks of flexible flat structures, especially sheets or printed products
摘要 Different stacks repose upon the lower section or run of an endless, revolvingly driven roller grate or grid arrangement. The return section or return run of the roller grate arrangement extends above or in overlying relation to the stacks. Below the stacks there travels a conveyor belt or band, whose conveying direction is opposite to the direction of movement of the roller grate arrangement. The rolls of the roller grate arrangement are obliquely positioned with respect to its direction of movement. Each stack possesses, at the region of the stack corner directed towards the oncoming or moving rolls, a separation element which draws the corner of the momentarily lowermost product between two rolls or rollers. By means of the subsequent rolls which travel between the lowermost product and the stack this lowermost product is separated from the stack and falls onto the conveyor belt or, as the case may be, onto products already reposing upon such conveyor belt. During the bringing together or collating of the individual products of the different stacks, each separated product is deposited in each instance upon the products or products which have already been separated from the preceding stack or stacks, respectively. The outfed collated or combined stack is therefore constituted by a respective product which has been withdrawn from each of the stacks.
