Description

The invention relates to devices for counting wound paper. By main auto No. 103681-9, a device is known for eliminating the re-counting of a paper layer removed from a roll, comprising a level sensor of paper wound on a roll made in the form of two tachometers, one. of which is mounted on the axis of the bearing shaft of the food-cutting machine, and the second - on the axis of the winding roll, and the control unit with a memory unit containing two ’counter-register and the comparison circuit SHCH].

However, the known device does not generate a control signal for the operating modes of the machine, in particular the signals Start braking, and Stop, which leads to the winding of rolls of different diameters in different times.

The purpose of the invention is the expansion of functionality.

This goal is achieved by the fact that an additional control unit, coincidence circuits and switching units, the inputs of which are connected bitwise with the corresponding outputs of the register counters, and the outputs with the inputs of the coincidence circuits whose outputs are connected, are introduced into the device to eliminate the re-accounting of the paper layer removed from the roll with inputs of an additional control unit.

The specified device, in addition to performing the main function of eliminating the re-counting of a layer of paper removed from the roll, generates signals · Start braking and Stop the machine when the specified roll winding radius is reached. .

The drawing shows a diagram of the proposed device.

The device contains a level sensor 1 of the winding roll, made in the form of two tachometers 2 and 3, one of which is mounted on the axis of the winding roll 5, and the second on the axis of the carrier shaft 4 of the machine, and a control unit 6 with a memory unit 7, containing two counters register 8.9 50 and comparison circuit 10, additional control unit 15, coincidence circuits 13 and 14, and switching blocks 11 and 12, the inputs of which are connected bitwise to the corresponding outputs of the counter-registers 8 and 9, and the outputs are connected to the inputs of circuits 13 and 14 matches whose outputs are connected to the inputs of the complementary Foot control unit 15 having outputs 16 and 17 Starting tsrmo / Kenya and stop respectively of

As a result, the machine start is inhibited.

When writing to the counter-register 9, the number of pulses from the output of the tachometer .3, equal to N _o . a signal appears at the output 17 of the additional control unit 15, with which the machine will stop.

The proposed device allows you to automatically control the braking and stopping of the slitting machine when the specified radius of the coil is reached at any winding speed, which allows winding coils of constant diameter.
