(54) DEVICE FOR CONTROL AND ACCOUNTING OF EQUIPMENT OPERATION

I

The invention relates to devices for the automatic control and recording of equipment operation and is intended for monitoring and recording the operation of ring machines, machines for spiral wrapping rings, machines for making wings, and can be applied to dispatch control systems or automated systems in the tire industry, rubber industry and other industries.

A device for monitoring and recording the operation of production equipment, comprising a power sensor connected to threshold elements and a single vibrator, a coincidence circuit, a revolution counter connected to triggers, a time relay and a memory unit connected to a trigger and a coincidence circuit, a time interval generator connected through a matching circuit with an adder, a finished product counter connected to a matching circuit, triggers and revolution counters 1.

The disadvantage of this device is the inaccuracy of the accounting products, caused by the instability of the operation of the time relay.

The closest in technical essence to the proposed device is

To monitor and record equipment operation, it contains a sensor, an alarm device, a memory element and an And 2 element.

The reliability of this device is not high enough, since all the elements of the device circuit work with the frequency of the sensor signals.

The purpose of the invention is to increase the reliability of the device.

Claims (2)

The goal is achieved in that a device containing a sensor, an And element, a simple counter, a production counter, a memory element, an alarm indicator and an addition counter are entered, a comparison element, a control unit, a multiplication unit and a subtraction counter, and a sensor connected to the first counter inputs. and a subtraction counter, the second inputs of which are connected to the first input of the comparison elements and to the first output of the control unit, the input of which is connected to the memory element, and the second output to the first input of the multiplication unit, the second input of which is with the output of the first comparison element, the third input with the output of the subtraction counter, and the output of the multiplication unit is simply connected to the counter, the output of the addition counter is connected to the second inputs of the comparison elements to the first input of the AND element, the second input of which is connected to the output of the first comparison element The output of the element I is connected to the output counter, the output of the second element of the comparison is connected to the signaling device. The drawing shows a block diagram of the device. The device consists of a sensor 1, counters 2 and 3, connected to comparison elements 4 and 5 and a control unit 6, a memory element 7 connected to a control unit 6, a smart block 8 connected to a subtraction counter 3 of the first comparison element 4, control unit 6, counter 9 is simply connected to the output of multiplication unit 8, AND 10, connected to the addition counter 2, of comparison elements 4 and 5 and multiplication unit 8, production counter 11, connected to the output of comparison element 10, alarm 12, connected with the release of element 5 comparison, the comparison element 5 is connected with the comparison element 4, the control unit 6 is connected with the comparison elements 4 and 5. The device works as follows. From the memory element 7 into the addition counter 2 is entered ZERO, and into the subtraction counter 3, the normative number corresponding to the number of sensor operations during normal operation of the machine during a time equal to the period of control of the work. According to the signals from sensor 1, the content of counter 2 is increased, and the content of counter 3 is subtracted, i.e.; counter 2 works on addition, and counter 3 on subtraction. After a time equal to the monitoring period of the machine, the control unit 6 from the memory element to the input of the multiplication unit 8 produces a number equal to the average value of the sensor 1 response period, and to the input of the comparison elements 4 and 5 produces a standard number. At the same time, at the output of the element 4, the comparison will result in a signal if the actual number of operation of the sensor of the sensor 1, entered into the addition counter 2, is less than or equal to the standard number. On this signal, the contents of the counter 2 add, through the element 10, enters the production counter 11. and the contents of subtraction counter 3 are fed to multiplication unit 8 for calculating the time simply, which is then entered into counter 9 simply. If during the monitoring period the counter of the 3 subtraction had time to be reset, then the entire contents of the counter 9 simply changes. If the content of the addition counter 2 is greater than the standard number, then the output of the comparison element 5 is the output of the signal to the detector 12. The proposed design of the device improves the accuracy of control, the accuracy of the accounting information for developing optimal equipment control.
