Description

see drive for pushing against the B & - current magnets, which can act to move gene edge brings certain tappet to effect. a plunger 6 is used. The plunger 6 has on his A pusher plate 4 for a specific sheet format and a fixed-free end. The plunger is in The low transport speed can vary from that of its rest position in the extended position, in the workhorse Sheet leading edge influenced light barrier 5 position drawn in dashed lines, the command to push the plunger against the for The electrical connections between the Transport direction parallel sheet long edge without light barrier and the preselection (not shown) each Delay on the electromagnet, the counter and between the electromagnet and The plunger drives, are passed on, even if the counter also not shown, gesteudie Light barriers in the same feed circuit to the transport direction run in the multi-core direction is vertical vertical plane, like the plunger. Cable 7.

Then the normal response delay is sufficient. With the housing 1 is an overarching bracket of the electromagnet connected to the plunger against tion 8, which has a threaded hole for a the middle of the longitudinal edge of this arc push forward to the clamping screw 9 and has a hole 10, sen. If the device is also intended for sheet formats with 15 F i g. 2 shows the device according to FIG. 1 in their longer longitudinal edges are set up, so must operating position on a processing machine. she the command to operate the plunger from the light is to one associated with the output of the machine Barrier delayed, namely rod 11 pushed open and clamped there. in the the delay must be equal to the time, those of the rest are only the exit arcs of the machine needs to see one half the length of the conveyor rollers 12 and 13. With 14, 14 'and 14 " differentiated between the edge of the sheet in the offset are the sheets and with 15 and 16 the conveyor belt position to be moved and the next to the delivery.

shorter longitudinal edge of one of the additionally usable The housing 1 is attached so that the sheet Cover the appropriate distance for other formats. The light barrier between the light source 2 and se delay times are very small, so that as the in FIG. 2 invisible receiver 3 Time interval between actuation of the light (Fig. 1) must happen. You interrupt barrier and the advance of the ram according to the light beam, whereby a counting pulse is sent to the a further development of the invention is issued in accordance with the preset counter, of the respective sheet measured in the conveying direction be adjustable by means of a potentiometer include 30 gene. The preset counter is therefore on the can, through which the delay time of an electronic number seven has been set, see delay element or the like. Can be changed. The six in the form of scales on the display Hegen-functional If the light barrier with the bend 14 has the offset device unbeeinßel and its drive combined in one housing, flows happens. With the entry of the seventh Boderart, that a light source and a receiver, especially 14 ', is the seventh counting pulse on the counter a selenium cell, in each of two discharges. Thereupon, as soon as the bow 14 ' runners of a fork-shaped housing are installed, was released from the output of the machine, a which contains an electromagnet whose movable short-term excitation of the electromagnet 5 is erased Armature is designed as a plunger. The housing loosens. As a result, the plunger 6 is out of the housing 1 may have a holder, for its attachment 40 vorntllt out into the position shown in FIG. 1 striam Output of a processing machine a chelt is indicated, and has 4 with its pusher plate Clamping screw is used. the sheet running straight through the light barrier In the drawing, an exemplary embodiment is pushed to the side so that this sheet 14 ' Device according to the invention shown. is now offset on the sheet 14. After that is the F i g. Fig. 1 is a side view of this device; 45 plunger 6 snapped back into housing 1, F i g. Figure 2 shows the device schematically in its so that the following six arcs, beginning Interaction with the processing machine and with the sheet 14 ", again only in the direction of transport the atrlage. the belts 15 and 16 shifted one above the other
