Abstract

A pile changing device for a printing press delivery mechanism which includes a first conveyor for delivering sheets from the press seriatim to a piling space, the sheets being accumulated on a pile board in the form of a skid. A track extends from the piling space to a second conveyor. A fork lift mechanism is provided having a carriage which is shiftable on the track. Control means, which is automatically triggered when the skid becomes full, causes the fork lift mechanism to remove the skid from the piling space and to deposit it on the second conveyor. Upon removal of the full skid from the piling space the control means causes feeding of an empty skid via a third conveyor from a skid magazine into a precise sheet-receiving position. an auxiliary pile board is interposed on the path of the delivered sheets during the brief interval when there is no skid in sheet-receiving position. In the preferred embodiment of the invention the fork, in addition to its shifting movement, undergoes lifting, lowering and rotational movement in effecting transfer of the full skid.
