Description

one

The invention relates to devices for the automatic control and recording of work, and can be applied in the systems of dispatching and automated production management for automatically recording the production of piece goods and simple equipment in all industries.

A device is known for automatically controlling and recording the operation of equipment, including its electron-pulse counters, sensors of the state of the equipment, a time relay, a pulse generator.

However, this device can take into account only the shear, its quantity of output by the Stake or site, without distinguishing between the range of finished products, which may differ from each other by the number of technological operations required for their manufacture.

The purpose of the invention is to expand the functionality of the device, i.e. implementation of automatic recording of output by the machine (unit) not only of the total quantity, but also of each individual size, as well as improving the accuracy of time control of just equipment.

This is achieved by the fact that the equipment status sensors are connected to matching blocks, the output of the first of which is connected to one of the inputs of the first AND circuit, the other input of which is connected to the output of the first memory -1H. The input of the first memory block is connected to the output of the second matching unit, and the reset bus of the first memory block is connected to the Soros busbar of the second memory clock and to the output of the reset circuit. The input of the reset circuit is connected to the output of the third matching unit and to one of the inputs of the second AND circuit, the other input of the KOTOpoii is connected to the output of the second power supply unit. The input of the second memory unit is connected to the output of the first AND circuit and to one of the key inputs, the other input of which is connected to the output of the first time relay n

the pulse shaper input. The output of the pulse shaper is connected via a switch to one of the meters of output. One of the inputs of the first time relay is connected to the output of the second circuit "And,

the second inputs of the first and second time relays through the switch are connected to the first and second time of the driver circuits. The key output is connected to the first input of the second time relay, the output of which is connected to one of the inputs of the third I. The second input of the latter is connected to a pulse generator, and its output is simply a counter.

The drawing shows a block diagram of a device for monitoring and recording equipment operation.

Sensors L 2 and 5 are connected via blocks 4.5 and 6 of the matching to one of the inputs of the first And 7 circuit, the input of the first memory block 8, and through the OOR circuit 9 to the reset buses of the first 6 and second 10 memory, the second output The I & P circuit is connected to the input of the first time relay 12, the relay output is connected to the key 13 and the driver of 14 pulses, the output of the control switch is to the second relay 15 of time. Relays J and 15, as well as the driver of 14 pulses are connected via the first (16 -16j), the second (Ub Idj) and

the third (- 16) position of the switch 16, respectively, to the first and the second time to set the G / a circuit. Jd to one of the counters W of the output. The inputs of the third circuit "and 20 are connected to a time relay 16 and a pulse generator 21, and its output to counter 2 is simple.

The device works as follows.

11 when a signal arrives from the sensor, signifying the beginning of the assembly cycle of a unit of production, through matching unit 5 to the input of memory circuit 8, the latter goes into one of the stable states. At one of the inputs of the circuit "And 7, the potential appears, i.e., the circuit" And prepared by one input. When the next assembly operation is performed, the signal from the sensor / through the matching unit 4 is fed to another input of the “AND 7” circuit. At the output of the latter, a signal is generated, the effect of which is the memory 10 and the “And //” circuit, as another input of the circuit “And prepared earlier by a signal from sensor 3 through the matching unit 6. There is a start at the input of relay 12 of time. But the expiration of the time required to manufacture a unit of a product with a certain number of operations and controlled time by the driving circuit 17, the installation of which is set by shifting the switch to one of the corresponding positions 16 (a, b, s, ..., 1) of the switch depending on the size of output appears at the output of time relay 12 and at the input of shaper 14 pulses. From the generator output, a pulse with a certain amplitude and duration is applied to one of the counters 19 of the output, switched by a switch to one of the positions (a, b, c, ..., /). There is a fixation of the unit of production.

Simultaneously with the appearance of a signal at the output of the time relay 12, the control key 13 is transferred to the opposite state.

A time relay 15 starts up, the delay time of which is set by one of the position 10 (a, and, s, ..., 1) of the switch. The setpoint is determined by the timing circuit 18. When a certain predetermined amount of time is exceeded, the output of the relay 1b receives a resolution signal to one of the circuit inputs AND 20 of this moment, the time is simply fixed by equipping the meter 22, to the input of which minute pulses go through the circuit. mu “And 26 / s generator 21.

From the moment the new product starts to be manufactured with the key 13, the signal from the output of the circuit “AND 7 is transferred to the initial state and the time is simply stopped by the equipment.

If the sequence of assembly operations is not followed, the signal to the relay 12 is not received and the unit of output is not recorded in the meter. The counter also fails in the event that at least one of the technological operations is missing during the assembly, since the device returns to its original state before the output of the relay 12 is signaled.
