Abstract
A device for conveying and piling flat workpieces includes a conveyor comprising side-by-side endless belts with a vacuum chamber for each belt, which vacuum chambers are interconnected to a common source of vacuum and which chambers are separated by ducts which are in communication with either atmospheric air or pressurized air and contain ejector levers acting on an elongated flexible element to eject a sheet from the belts and to break the suction from the vacuum chambers on the sheet by uncovering openings in the ducts to supply air at atmospheric pressure or pressurized air to each of the vacuum chambers. The conveyor places the sheet in a piling store, which can then be removed as a batch of a certain number of sheets.
