SU580569A1 - Device for comparing the quantity of planned production with actual value - Google Patents

Description

The invention relates to devices for monitoring and recording the operation of machines and apparatus, and is intended to compare planned and actual production of products.

Devices are known for controlling the production rhythm by comparing the planned and actual production of products using an information board. In these devices, the information display shows the actual value of production in this area, as well as the planned task for a certain period of working time, such as shifts, days, ten-day, etc. 1. These known devices are characterized by the impossibility of quickly assessing the production situation, as the planned task is not displayed in real time (i.e. the information corresponds to the planned task at the end of the monitored period of working time). The closest technical solution to the invention is a device for comparing the planned and actual production of products, comprising an actual output sensor, a pulse generator and a switch block 2. However, it is inconvenient in operation due to the discrete temporal nature of the displayed information; in addition, it is inconvenient to use it for the purposes of dispatching control and regulation of production.

In order to simplify the proposed device, a time marker generator, a scoreboard and a serially connected frequency divider, a counter and a switch are introduced,

a pulse generator, a time stamp generator and a switch block are connected to the corresponding inputs of the frequency divider, and the actual output sensor is connected to the input of the switch, the outputs of which are connected to the scoreboard iK.

The drawing shows a diagram of the proposed device.

It contains the board 1, controlled by switch 2, one of the inputs of which is plugged into the sensor 3 of the actual output. The second input of the switch 2 is connected to the output of the counter 4, the input of which is connected to the output of the frequency divider 5 connected to the switch block 6. The counting input of the divider 5 is connected to the generator of 7 pulses, and its triggering input is connected to the generator of 8 time marks.

Before starting work, the operator (dispatcher) sets in block 6 the value of the division factor of divider 5, equal to the planned target of the manufactured products for the planned working period of time. Next, the device works automatically. The generator 7 continuously generates pulses arriving at the counting input of the divider 5. In the case of the trigger pulse coming to the trigger input of the divider 5 from the generator 8 output, it passes the number of pulses to the input of the counter 4, paiBHoe to the value of the division factor at block 6. With the arrival of the next pulse, the trigger input of the divider 5 is repeated, and "and the input of the counter 4 receives the next packet of pulses. The division factor of counter 4 is constant and is equal to the number of generator pulses; there are 8 time stamps issued by it for the time period for which the production task is planned (shift, day, decade, etc.). In connection with this, the frequency of the signals arriving at the switch 2 exactly corresponds to the reciprocal of the planned task on the / input of the counter 4, and the device is synchronized with the astronomical time using the time stamp generator. The switch -2-after the arrival of the next control signal commutes on board 1 (its planned part) the next combination of digits corresponding to the planned task for the given time moment. From the actual generation sensor 3, in the case of manufacturing a regular part (assembly), a pulse arrives at the second input of switch 2, which translates the display 1 (“the actual part) into a position corresponding to the regular combination of its significant digits. By comparing the planned and actual output values, it is possible to control the rhythm of the production process at any point in time. Thus, the proposed device allows to simplify management by setting on the keyboard of unit 6 directly the value of the scheduled task for a predetermined period of working time. In addition, D01st, the accuracy of operation of the device as a result of setting the exact value of the scheduled task, when the number of products produced in the planned time interval is arithmetically times the number of time intervals in this interval, is needed. Apparatus of the Invention A device for comparing the planned and actual output of a product, comprising an actual output sensor, a pulse generator and a switch block, distinguished from the fact that, in order to simplify the device, a time marker generator, a scoreboard and serially connected frequency divider are inserted into it , a counter and a switch, the pulse generator, a time stamp generator and a switch box are connected to the corresponding inputs of the frequency divider, and the actual output sensor is connected to the input of the comm tator, the outputs of which are connected to the board.
