Description

The output of the block for determining the number of the defective device is connected to the input of the block 8 of the memory of all channels. The counter 9 position pulses of the product of all tracking channels receives pulses when there is a enable signal from the output of the code comparison unit 10 through an AND 11 logic element, another input of which is connected to the output of the position sensor 6 of the finished loop.

The device works as follows.

When a defect is detected on an infinite workpiece 1, the workpiece quality control sensor 2 generates a signal from the inputs of the unit 3 for determining the number of the defective product 4. The number of the defective product is determined by comparing the signals from the cut sensor 5 and the sensor 6 of the finished product, the outputs of which are to the unit determining the number of the defective product and the quality control sensor 2 of the workpiece. At the same time, the signal from the quality control sensor is fed to the input of the switch 7 of the channels of the finished product, which switches the switch and the next channel. The rejected item number enters memory block 8 of all channels, however, it is recorded only in the one to which the signal from switch 7 is fed. At the time of writing to the memory block, the counter 9 of the position pulses of the product is in the outgoing state, i.e. in the zero position. In this case, at the output "more than block 10 of the comparison of codes, a sitnal appears, which through a logical element AND AND allows the input to the counter 9 of the signals from the sensor of the final product. These signals stay until the number in the counter is larger or smaller than the number recorded in the block. For example: the register contains the number 15.45, and the number in the counter is 13.0. In this case, the block compares the meter to get three more pulses. When the number in the counter is 16, which is larger than the register, the comparison unit returns the channel to its original state and issues a signal to sort out the sort.

Thus, the device can work

immediately all the channels or some of them. In each specific case, the number of channels is determined depending on the maximum rhythm mode in the technology of operations at a given grading site.
