Device for loading a three-knife trimmer

Abstract

In a device for loading a three-knife trimmer with brochures, periodicals or like bound book blocks (1), comprising a feed conveyor (4), a stacking device (16) operable in magazine mode and counted stack mode and including a magazine (17) having a first upper magazine intermediate shelf (18) and a second lower magazine intermediate shelf (25), and comprising a delivery table (28) arranged below said magazine (17) and an ejector (29) for cyclically and synchronously feeding a stack (3) of book blocks to the intake device (35) of the three-knife trimmer, it is provided that the feed conveyor (4) is formed by a conveyor belt (5) continuously driven at a first velocity (vS) and by an accelerator conveyor (6) located directly downstream thereof in the feed direction and driven at a higher velocity (vB), and that a separating device (11) for book blocks (1) supplied in an imbricated flow (2) is arranged in the transition zone from the conveyor belt (5) to the accelerator conveyor (6) for holding back a following portion of the imbricated flow, whereby a gap is created in the imbricated flow (2) for the opening and closing of the first magazine intermediate shelf (18). The device is characterised by its simple construction and makes possible a high feed rate, in particular for thin book blocks.
