This invention relates to a weight-measuring technique.

The aim of the invention is to increase speed, increase accuracy, decrease size and energy consumption.

FIG. 1 shows a block diagram of the device; in fig. 2 - time diagram of the device operation.

The diagram shows the axis 1 of the gear pair, connected to the arrow of the metering head, gears 2 and 3, selsyn-sensor A, selsyn-receiver 5, potentiometric sensor 6, first 7 and second 8 pulse formers, 9 pulse generator, assembly And - OR 10, third driver 11 pulses, analog-to-digital converter (A1SCH) 12, fourth driver 14 assembly pulses AND 14 and 15, fifth driver 16 pulses, AND circuit 17, counter 18 gross, counter 19 weight of the container, sixth driver 20 pulses, memory block 21, assembly OR 22 and block 23 in diction

The device works as follows.

When the discharger unloading relay is triggered, the signal to the input of the pulse generator 7 (Fig. 2a) is converted into a pulse, during which L1Sh 12 converts analog information from the potentiometric sensor 6 and the corresponding angle of rotation of the axis of the arrow of the measuring head 1 transmitted through gears 2 and 3, selsyn-receiver 4 and selsyn-sensor 5 to potentiometric sensor 6. According to the decay of the pulse at the output of the pulse former 7, the pulse former 11 generates a pulse gate counter Gross and 18 (FIG. 2c), which via gates 14 and assembly rewriting information A1SCH 12 into the counter 18 gross. When the load relay of the metering device is triggered, a pulse of line conversion (Fig. 2e) is formed at the front of the signal at the input of the pulse former 8 (Fig. 2d), its output converts the analog information from the potentiometric sensor 6 corresponding to the weight empty hopper dispenser.

shaper driver 8 shaper 13 forms a strobe pulse of a tare weight counter 19 (Fig. 2e), which gates, using the AND 15 assembly, overwriting information from ALUI 12 into a tare weight counter 19. By the pulse decay at the output of the pulse former 13, the former 16 generates a strobe pulse of the inverse counting (Fig. 2i), during which, if the number other than zero (Fig. 2g) is recorded in the tare weight counter 19 (Fig. 2g), i.e. . assembly output OR

22 logical level 1, sequential subtraction is performed from the tare weight counter 19 and the gross counter 18 until the number recorded in the tare weight counter 19 is zero and the pulse of the output pulse OR 22 is removed from the output gate of the inverted counting And 17 ( Fig. 2h), if zero is recorded in the tare weight counter, the pulse from the output of shaper 16 does not pass through the AND 17 circuit and the inverse counting mode is absent. By the decrease of the pulse at the output of the pulse former 16, the former 20 generates a write strobe pulse into memory block 21.

(Fig. 2k), according to which the information from the counter 18 is grossly overwritten into the memory block 21 and fed into the block

23indications.

Thus, the proposed device makes it possible to determine the net weight of the dosed material in each cycle of the dispenser and accumulate information about the consumption of material in the memory unit.
