Device for inserting the cutting knife into the cutter bar, in particular from Papi ersehne id e «~

machinery"

S ch / se]

The insertion of the tendon knives into the measuring instruments « serbalicen of paper cutting machines has been carried out so far, that the cutter is placed on the cutting table and then the cutter bar is moved down until

he has arrived in the insertion position for the knife * During this process, the knife must be stopped by the operator so that the knife bar is also precisely positioned. can be driven »The insertion is therefore relatively time-consuming and cumbersome, especially since the cutter bar from Hand must be brought into the insertion position. Furthermore, there is the risk that during the retraction of the beam the operator can easily injure himself in the knife.

The invention now relates to a device for inserting the cutting knife into the cutter bar of in particular Paper cutting machines that make it possible to insert the knife into the knife bar quickly and easily, that the press beam is provided with a holding device that accommodates the knife to be used, so that when it is raised of the press bar the knife is brought into the insertion position on the knife bar * There is a holding device of at least two support screws that can be inserted into the press beam, which are in the area of the knife support with one of the knife edges adapted incline are provided. placed so that the knife is well guided in the gap that is formed by the slope of the support screw and the elastic Seheibe is*

The invention is explained in more detail below with reference to the exemplary embodiment shown in the drawing demonstrate:

Pig, 1 is an erased representation of a cutting machine with the knife to be used in the knife sharks

Fig * 2 a vertical section to this «

As shown in Fig. _# 1 and 2, the Bressbalken is shown once in the lower position in solid lines and once in the upper position in dash-dotted lines of the press beam is carried out by hydraulic means »Two visual hoods 3 are inserted into the press beam, which have a slope 9 * Between the press beam 5 and screw 3 or * the slope 9, an elastic washer is inserted so that the knife 4 in the gap between slope 9 and disc 10 is guided »The press beam 5 is moved by a hydraulic system 8 *

The knife 4 is inserted into the knife holder 2 in the following way:

First, the press beam is lowered onto the cutting table 7.

driven * In this position the knife h to be used is placed on the support screws 3 in the position as shown in Pig _# 2 in solid lines. The cutter bar 2, however, is in its upper position * If now the press beam, that is moved 5 in the upper position in dot-dash position, then passes the knife * t in the region of the cutter bar 2, d _# h _# it is so far raised until the knife comes to rest on the shoulder of the knife bar and thus the fastening screw 6 can be inserted into the bores of the knife 11. The support screws 3 are then unscrewed from the press beam so that the press beam is ready for use again _#
