Device for depositing individual printed products, supplied in succession, in shingle formation

Abstract

A device for depositing individual printed products (4), preferably magazines, brochures or book blocks, that are supplied in succession by means of a feed conveyor (2) on a downstream conveyor (3) with slower transport speed (v3) in shingle formation (5), wherein said device comprises a stream feeder (1) that receives the printed products (4) from the feed conveyor (2) by means of rotating grippers (6a to e) that are opened and closed in the appropriate cycle with the aid of a stationary cam (12) and deposits the printed products on the downstream conveyor (3). In order to reliably and flawlessly deposit the printed products, particularly thick and/or less flexible printing products, in shingle formation, the stream feeder includes a plurality of grippers (6a to e) that are rotatively driven with a slower speed (v2) than the feed speed (v1), wherein the grippers (6a to e), opened for receiving the printed products, respectively include a short pocket (7) with a bottom stop (8), with which the respectively supplied printed product (4) comes in contact due to the higher feed speed (v1). The clamped transport takes place within an angular range (β) of the rotational movement of the grippers, namely up to a defined distance upstream of a stripping element (10) for reliably releasing the printed products (4). They drop on the downstream conveyor (3) along a short path.
