The main patent is based on the task of door assembly and to design door protection in such a way that a single safety element correspondingly linked to the machine control system always a machine shutdown or piston drive blockage occurs when one of the two doors is opened.

The design according to the main patent solves this problem simple Uleise by a common, mechanical switching element in connection with one likewise mechanical and from the latter actuated limit switches, however, practice has shown that these mechanical actuators are also technically untrained Operating personnel can be put out of function relatively easily can, without a shutdown or blocking of the sturgeon drive the waste press enters. Serious accidents and injuries can occur as a result.

This supplementary invention has therefore set itself the task of remedying this supernatant and to create a backup device in which due to their nature, effect soijie their schaltungsgemä'en V / erknüpfung with the press control a AuSerbetriebsetzEn same Z'jangsläufig shutdown BZÜ ^first Blockage of the press drive.

The drawing shows schematically an embodiment bz'-i. Arrangement example of the invention shown and based on its function this drawing explained in more detail.

Show it:

FIG. 3 shows a plan view of FIG. 2.

According to !? the perspective system representation in Fig. 1 mostly the depicted press in itself known! Jeise the one on top of the other lying areas of the drive elements a, the filling chute b and the actual Pre ^ space c.

Filling and PreSchacht b and c are covered by a door element 2, which can be swung out horizontally together via valuables warehouse 1, with locking mechanism 3, and in the door frame 2a for the area of the filling chute b, there is also an additional, horizontally pivotable Klanpe 5 with its own, which can be pivoted horizontally about axis h

Lock 6 is arranged. On the frame 5a of this flap 5 is now seated in a corresponding recess 2b of the frame 2a the shaft door 2 a so-called switching flag 13 or the like Actuator for the activation of the arranged on or in the housing G, electronic proximity switch 14 with electrical Connection or link 15 to the machine control, not shown.

The effect of this double, i.e. together on or for the two door elements 2, 2a and 5, 5a acting safety device bzui. The limit switch is now as follows:

a. By releasing the lock 6, the flap 5, 5a with their essentially vertical component of movement Closed down, i.e. opened, moves

the switching flag 13 according to the arrow P ^ in Fig. 3 by rotation about the axis h out of the inductive zone "s" below the electronic proximity switch 1if and the lack of damping of the switch 14 gives the machine control the impulse

to switch off the press.

b. If, however, the door 2, 2a after unlocking the elements 3 on the bearing 1 according to arrow P “opened and swiveled out, causes the horizontal sliding out of the

In order to effect this shutdown as early as possible at the beginning of an opening process, - _{dash-dotted lines at P 1} and P "- the switch 1 '+ is as far as possible L-eit from the two Schue-ikaxial 1 and k in the outermost corner area of the doors 5, 5a or 2, 2a arranged. Such a door lock cannot be put out of operation in a simple manner, i.e. without intervening in the electrical control.
