Device for setting a book-block transportation system, especially for adhesive binding machines

摘要

The invention is applied in adhesive binding machines for setting the distance between the individual plates of a plate chain to the thickness of the book block. The object of the invention is to achieve correct setting without physical stress. The said object is achieved in that a calibration point (4; 5) is arranged outside the transportation system (3; 7), the setting value of this calibration point being transferred to the transportation system by means of a setting spindle (2; 2'). To this end, the calibration point is provided on the machine frame, analogously to the measurement point within the transportation system, and has the same spring characteristic as the plate chain itself. Via a setting spindle (2; 2'), the book block 6 which is to be processed is clamped by a geared motor (10) between two plates (3; 7), one of which is of resilient design. The spring force achieved can be read off from a scale (9). The setting spindle (2; 2'), for its part, is connected via a pair of bevel gears (12) to a setting shaft (14) which transmits the movements of the setting spindle (2; 2') to adjustment shafts arranged parallel thereto. Uniform adjustment of the entire book block transportation system is thus possible. IMAGE
