DE3603218A1 - Device for setting a book-block transportation system, especially for adhesive binding machines - Google Patents

Abstract

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>

Description

Device for setting up a book block transport system. especially for perfect binding machines.

The invention is described in Buchb Io ck t ran sp or t systems, in particular in Klcbinding machines to adjust the distance between the individual Plates of a plate chain applied to the book block thickness.

A / In the DD-PS 111 330 a Pia11enke11enfuhrungsbah η for bookbinding machines, especially for hemming and perfect binding machines shown. The book blocks are held between zvvsi plate chains, one of which is rigidly mounted and the opposite plate chain movable to adjust the book block thickness to be processed is arranged. This setting is done by means of adjusting screw η and lock nuts. In the further development, the plate chains are made using of a handwheel. For this purpose, a book block is inserted at a measuring point within the transport system after beforehand a corresponding change in the plate chain position took place. It is then delivered until the required Pressure on the outsides of the block is achieved. so the transport system must be opened again for the necessary removal of the measuring block, counting the number of turns of the handwheel. This is followed by the same number of revolutions of the handwheel again the delivery up to the measured value.

This setting is with heavy exercise and long response times. Besides, the setting is relatively imprecise, as the final setting is only made by repeatedly counting the number of revolutions of the handwheel.

The aim of the invention is to avoid time-consuming and strenuous manual adjustment work, which could have subjectively influenced deficiencies in the bookbear during processing.

Π The invention is based on the object of a device to create, with which a precise determination of the to be set Size of the distance between the plate chains is made possible and the This value can be set automatically. The object is achieved in that a calibration point is arranged outside the transport system, its setting value by means of an adjusting spindle via a pair of bevel gears on an adjusting shaft and from this over several adjusting shafts to the resilient one Disk chain side is transferred. This is done on the machine frame analogous to the measuring point located within the plate chain, this calibration point was created, which dis the same spring characteristics like the resilient pattan chain side itself. A gear motor is driven by an adjusting spindle of the book blocks to be processed between the two plates of the Calibration point, one of which is resilient, clamped. The required pressure can be read from a scale, for the safe tensioning of the search blocks to be processed in the Plate chain is required. A limit switch is provided to avoid excessive pressure. The one in the calibration point The jammed book block remains until the respective one is processed Lot in this position. In contrast to the previous setting of the book block transport system using a handwheel the device according to the invention the prerequisite for automation the adjustment process.

work is eliminated while at the same time improving the setting quality and shortening the setting times. It is also possible to extend the application of the central distribution according to the invention to successor modules.

The invention is to be described in more detail on the basis of an exemplary embodiment explained. It shows:

Fig. 1 is a side view of the device for setting a book block transport system.

In the housing 1 is an adjusting spindle 2; 2 ' stored. On the gable wall of the housing 1, the resilient part of the calibration point 4 with the same spring characteristics is arranged analogously to the spring-loaded plate chain side 3. On the spindle 2 there is the counter-plate 5, which has the same height dimensions in relation to the resilient part 4 as the plate chain side 7 in relation to the resilient plate chain side 3 manufactured. The resilient plate chain side 3 is firmly connected to the adjusting spindle 2 '. The plate chain side 7 is arranged on the housing 1. The gear motor 10 initiates the rotation of the adjusting spindle 2; 2 "via a sprocket 11. Ü'osr a pair of bevel gears 12 and an adjusting shaft 14 are arranged parallel to the adjusting spindle 2; 2 'and also with the resilient plate chain side 3 over the entire Length of the plate chain reached with the required uniformity. A display scale 9 and an end switch 13 also belong to the calibration point 4; 5.

By adjusting the adjusting spindle 2; 2 "will be both the plate chain 3; 7 like the calibration point 4; 5 opened so wide that one of the book blocks 6 to be processed can be inserted, the one in it remains until the other book blocks of the same lot have been processed. By turning the adjusting spindle, this book block 6 compressed by means of the counter plate 5 so far that a solid Hold the book blocks S in the plate chain 3; 7 is guaranteed and a corresponding processing of the book blocks 6 is possible. By means of the display scale 9, the correct pressure can be set on read the book block S inserted in the calibration point 4; 5 will. The limit switch 13 prevents overload.
