Description

The invention relates to the control and recording of the production process, is intended to compare planned and actual production workings and can be used, for example, in conditions of conveyor production.

The purpose of the invention is to improve the accuracy of the device by controlling the dynamics of output.

The drawing shows a block diagram of the device.

The device contains a series-connected pulse generator 1, the first counter 2, the first code comparison unit 3, the switch 4 and the indicator 5, production output sensor 6, the second counter 7, the second code comparison unit 8, the register 9 and the switch unit 10, the first 1 1 and second 12 delay elements.

The device works as follows.

Before starting work on the block of 10 switches, time marks and the planned output rate of the products are set on each switch group. On the first group of switches, the start time of the shift and the planned output rate of the output (in seconds, minutes), which should be below the medium shift, are set. On the second group of switches, the time of the expected end of the production period and the planned output rate at the level of the medium shift are set. On the third group of switches, the transition time is set to a planned output rate exceeding the average shift. On the other groups of switches, the time and the planned output rate are set in the same way, taking into account interruptions in work (after each break, the planned output rate is set slightly below the average-change rate, and then - out). The counter 2 and the register 9 are reset to their initial state through their installation inputs along the circuit of the initial installation of the device (not shown). On counter 7, the current time is set. The pulse generator 1 continuously generates pulses arriving at the counter 7 and the second delay element 12. At the output of counter 7 there is a code corresponding to the time. This code is fed to the second input of the second block 8, the first input of which is connected to the output of the delay element 12, and the third to the first output of the AND block of the switches. Before the start of the shift on the first digit of the register 9, there is a signal that connects the first group of switches of the switch block 10. Thus, at the third input of the second block 8 there is a combination corresponding to the start time of the work shift, and when the state of the counter 7 coincides with this value, a signal appears at the output of the second block 8.

which brings the shift register to the next state (the signal appears at the second output bit), and a second group of switches of the switch unit 10 is connected. The gating of the comparison operation of the codes arriving at the second and third inputs of block 8 is performed by the second delay element 12. Strobe pulses arrive at the first input of the block.

It is delayed, which excludes the possibility of accidental coincidence of codes at the inputs of block 8 when switching over counter 7. From the output of block 10 of switches to the input of first block 3, a code is received corresponding to the specified one for the generation period

5 planned rate of output. With the next coincidence of the code values of the counter 7 and the switch 10 block installed at the output, the register 9 connects the next group of switches and to the input

Q block 3 sets the planned output rate.

At the same time, the pulses from the pulse generator 1 are fed to the input of the first delay element 11 and the counter 2, which sums these pulses and from its output

5 to the input of the first block 3 receives a code corresponding to the state of the counter. A code corresponding to the currently planned output rate was set on a different input of block 3 from the block of 10 switches. The gating of the comparison operation of the codes arriving at the third and second inputs of the block 3 is carried out by the first delay element 11 m. Strobe pulses arrive at the first input of block 3 with a delay, which excludes the possibility of random coincidence of the codes at the inputs of the coincidence circuit when switching the counter 2. When the codes coincide at the inputs of block 3, a signal appears at the output of it that switches to switch 4 and simultaneously translates counter 2 to the zero state. Commutator 4 after the arrival of the control signal commutes on the indicator 5 (the planned part of it) the next combination of digits corresponding to the planned task at the moment. Counter 2 starts a new counting of pulses and when the codes on the inputs of block 3 coincide, the next control signal goes to switch 4, which commutes another combination of digits on the planned part of indicator 5.

0 From the sensor 6 production output in the case of manufacturing the next part (node), a pulse arrives at the second input of the switch 4, which translates the indicator 5 (its actual part) to the position corresponding to the next combination of its significant digits.

On Efem of planned breaks, the switch unit sets the output output to zero, and the signal from the first output of the switch block prevents counter 2 from counting pulses from the pulse generator 1.

By comparing the planned and actual values of output, fixing the lag of the actual production of products from the planned and revealing the reasons for the lag, you can quickly manage the production process.
