Device for receiving an overload in a spine processing station of a book binding machine

Abstract

The invention provides a device for receiving an overload in a spine processing station of a book binding machine. In order that the back of the body which inserts into a clamp and is conveyed at the back processing station may process it, show around through between a support roller of position fixing, and press rollers in the state where it was inserted, and the press roller, linear movement is possible and so that thickness of the back which should be processed may be adjusted via a linear guide and a spindle driving device the spindle driving device, with an adjusting driving device, a spindle with a screw thread pivotable at a motor ceremony, It has a slidable internal thread mountain element to a spindle with the screw thread accommodated in rotation impossible, a spring elastic component connected with the spindle driving device is provided, and this spring elastic component, it is set up by an interval between the press roller and the support roller, which can be grasped by a sensor in order that displacement of a spindle with the screw thread may be enabled and the displacement may specify page number of the body, when target thickness of the back guided in between the press roller and the support rollers is exceeded in equipment which absorbs an overload. A driving shaft of the adjusting driving device, and an end by the side of an adjusting driving device of a spindle with the screw thread, it is slidably connected mutually impossible along a rotating shaft line of a spindle with the screw thread via a length compensation element, the spring elastic component is the inside of a hollow chamber provided in a housing of a spindle with the screw thread, equipment which having extended in same axis to a rotating shaft line of a spindle with the screw thread, and being supported by the driving shaft at the first end, and supporting inside a housing of a spindle with the screw thread at the second end and which absorbs an overload.

Description

technical field [0001] The present invention relates to a device according to the preamble of claim 1 for receiving an overload in a spine processing station of a bookbinding machine. Background technique [0002] EP2133212A1 discloses a spine processing station for a bookbinding machine, in which spines of book blocks transported suspended in a gripper are clamped during the processing of the corresponding spines by a milling device It is guided tightly through between the stationary support rollers and the pressure rollers which are arranged in the linear guide so as to be adjustable relative to the support rollers. In this case, in order to avoid damage to the threaded spindle, which moves the pressure roller in the direction of the spine, in the case of a book block with an excessive thickness, the threaded spindle is accommodated on a guide which passes through the spaced side. A helical compression spring, which is arranged laterally beside the threaded spindle-longit...

AI Technical Summary

Problems solved by technology

[0003] Due to the consequent positional offset with the tipping of the guide, a high-precision thickness sensor (with which the deflection of the guide relative to the machine part fixed on the machine frame can be detected) number of excess pages of the book block) can only be set with significant precision limits
