Abstract
Loader of signatures or sheets with scale-shaped arrangement comprising a retractable plane (10) onto which a small stack (7) of signatures or sheets (3) is deposited, which is unloaded onto the plane (2′) of a feeder (2) after the retractable plane (10) has moved back. The latter is located at a minimum difference in height relative to the horizontal upper part (5′) of a conveyor belt (5) of the signatures or sheets (3) coming from the loader (1) and at a short distance from the plane (2′) of the feeder (2).
Claims5
A loader of signatures or sheets (3) with scale-shaped arrangement to be deposited onto the plane (2′) of a bookbindery feeder (2), characterized in that it comprises a retractable plane (10) onto which a stack (7) of signatures or sheets (3) is deposited which lies at a minimum difference in height relative to the horizontal upper part (5) of a conveyer belt (5) for signatures or sheets (3) with scale-shaped arrangement, so that as a result the stack (7) on the retractable plane (10) is low, and which is located at a short distance from the plane (2′) of the feeder (2) and offset from the mechanisms (14) of the feeder (2) which is then downloaded onto the plane (2′) of the feeder (2) after the retractable plans (1) has moved back,
- and a level sensor (18) which detects the lack of a stack or the presence of a stack which is too low (21) on the plane (2′) of the feeder (2) and causes the retractable plane (10) to move into the path of the signatures or sheets (7) as they fall from the conveyor (5) so that a small stack (7) thereof will be loaded onto the retractable plane (10).
