Abstract

Automatic power-on device ripping paper copy checks can be used in the field of computer technology for the copy paper separator from the print computer reports. For now used separators are not needed for lanes when separating in the case of a smaller one than the number of copies designed, perform manual shutdown control ripping paper. On The diagram shows the separator device with three copy paper reels. When the separator starts with rheostat controlling the motor winds the copying paper to one or more copies reels and switches the switch from 1-3 to 1-2 and charge the corresponding capacitor. If the copy paper breaks in the track, pulling the corresponding spring switches the switch back to position 1-3 and charge appropriate the capacitors through the corresponding diode and the delay circuit discharges to the switch circuit that disconnects the motor from voltage.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically switching the ripping paper break when it is separated. For the copier paper separators used so far, it is necessary to turn off the ripping control manually for paths not used for separation in case of a smaller number of copies than the separator is designed for.

SUMMARY OF THE INVENTION The subject of the invention is an apparatus for automatically switching on a ripping paper rupture connected to a power supply circuit, the output of which is connected to a capacitor via a switch that is connected to a copying paper lever mechanism and connected to a motor switching circuit via a delay circuit. By eliminating the manual shutdown of unused tracks, the operation of the separators is accelerated and simplified.

A schematic block diagram is shown for the separator with three copying paper reels.

A 220 V mains voltage is connected to terminals A and B, which is then fed through the control rheostat R and the switching circuit SO to the motor M. At the same time, the line voltage is supplied to the NO supply circuit, at the output of which is a DC voltage suitable for controlling the switching circuit These are connected via diodes D and via the delay circuit Z0 to the switching circuit SQ.

The operation of the device according to the invention is as follows: When starting the separators with the control rheostat R, the copying paper starts to wind on the reel or according to how many copying papers are separated and into which paths they have been inserted. By tensioning the coiled copier paper, the respective Sp switch switches from position 1-3 to position 1-2 and charges the corresponding capacitor C. If copying paper breaks when the separators run, the contacts are folded back due to the loss of copying paper and the spring of the spring. the switches Sp to position 1-3 and the charge of the capacitor through the diode D and the delay circuit Z0 discharges into the switching circuit SO which disconnects the motor M from the voltage. The delay circuit has the task of eliminating short-term folding of the switch contacts, which is caused by the variation of the copying paper pull during separation. The entire circuit returns to its original state after releasing the control rheostat R.
