SU559102A1 - Device for measuring the size of products by rolling - Google Patents

Description

carry, connected to the second inputs of the control units 3, 4, controlled doublers 7, 8 frequencies, connected by signal inputs to the first outputs, and controlled inputs to the second outputs of the 5 3, 4 control blocks, computing unit 9, connected to the control outputs Doublers of 7.8 frequencies, and a registration unit 10 connected to the output of a computing unit 9.10. Each control unit contains a delay line 11, the output of which is a switch. It is connected to the signal input of the key element 12, and the time relay 13, the output of which is connected to the control input of the key 15

item 12.

The device works as follows

When roller sensors 1 and 2 roll back a flat part of the measured product, the sequence of pulses from both roller sensors goes through delay line 11, key element 12 of blocks 3, 4 of control and doublers-7 and 8, passing pulses without doubling, to computing unit 9.

At the moment of collision of one of the roller sensors, for example, 1, irregularity is triggered by sensor 5 and irregularities through the time switch 13 prohibit the passage of pulses through key element 12 and simultaneously issue a command to double pulses from roller sensor 2 to doubler 8.

When a roller sensor 1 degrades with irregularities, the sensor 5 irregularities through the time relay 13 with time delay removes the prohibition of the passage of pulses through the key element 12 and stops doubling of the pulses by doubler 8,

When driving over the unevenness of the roller sensor 2, it is produced; similar operations.

 Thus, the proposed device allows one to remove from the result of the calculations the distorted sequences of pulses arising both when driving and when the rollers descend from an unevenness, and to replace them with a sequence of pulses from another sensor that runs around a flat surface. In addition, when the sensors are running around a flat surface, pulse sequences are averaged.

In order to improve the accuracy of the measurement, the device is equipped with two sensors of unevenness mounted on roller sensors and two measuring channels, each of which contains a control unit, the first input of which is connected to the output of the corresponding roller sensor, and the second - to the output of an irregularity sensor, and a controlled frequency doubler, the signal input of which is connected to the first output of the control unit of the same channel, and the control input connected to the second output of the control unit of another channel.

2. The device according to claim 1, which is such that the control unit of each channel is designed as a key element, the signal input of which is connected via a delay line to a roller sensor, and the output to a signal element the input of the controlled frequency doubler of the same channel, and the time relay, the input of which is connected to the roughness sensor, and the output to the control input of the key element and to the control input of the controlled doubler of the other channel.
