Description

The invention relates to mechanical engineering and may find application in the construction of automatic lines.

The aim of the invention is to increase the reliability of control and improve operating conditions due to the invariance of the device to external factors ”(mountains.

The drawing shows a functional diagram of the described device.

The device contains sensors 1-4 of the presence of a part on each machine of the line, a control indication unit 5 made of elements 6-9 of an individual (for each machine) light signaling located on a mnemonic display, an element 10 of a general light signaling. Between the sensors 1-4 and the control indication unit 5, an indication control unit 11 is included, comprising a switch 12, a pulse generator 13, and logic counters 14-17.

Each of the logical counting elements 14-17 is connected to the output of the corresponding sensor 1-4. Outputs: 18-21 logical counting elements 14-17 are connected to the control input 22 of the switch 12 and the corresponding elements 6-9 of the individual light signaling. The control inputs 23-26 of the logical counting elements 14-17 together with the switch 12 are connected to the output 27 of the pulse generator 13. To the output 28 of the switch 12 is connected to the element 10 of the General light signaling.

A device for monitoring the operation of an automatic line operates as follows. .

In the process of monitoring the operation of the automatic line, the generator 13 generates calibrated frequency pulses, which from the output 27 go to the control inputs 23-26 of the logical counting elements 14-17 and to the switch 12. Since the time spent on the part on each machine is different, the settings are different logical counting elements 14-17 installed in the block 11 control indication. If there is no part on any machine, one of the sensors 1-4 is activated, which includes the corresponding element 14-17. If the time of absence of a part on machine ‘exceeds the norm, then pulses of a calibrated frequency fill all the bits of the logical counting element, the last one is triggered, the signal from its output goes to the corresponding individual light signaling element and control input. 22 of the switch 12, which in turn connects the element 10 to the output of the generator 13. A flashing light of the general light signaling element 10 indicates to the operator a fault in the line, and the glow of a specific individual light signaling element indicates the place and nature of the malfunction.

The use of a pulse generator and logical counting elements in the device allows for high-quality control over the operation of the machines for a single time, the count of which does not depend on any external factors, since the response time of the logical counting elements will depend only on the frequency of the pulse generator.
