The device performs loading portions of bulk cargo, which have a limit on the height of their fall during loading, in automatic or semi-automatic modes.

In order to load disposable cargoes into the transport container in automatic mode, the operator dials on the dial

field 28 the number of portions of cargo to be moved to the transport capacity.

The volume of the displaced cargo can be specified in the form of the number of portions determined by the distance between adjacent filling sensors placed in the bunker-daughter to limit the height of the load falling, or as the number of full metering bins

In the first case, the operator presses the A5 Portion button on the remote, in the second case, the Bunker button 44, and then the Start button 1.

On a signal from button 1, the Start is set to the single state of the sixth trigger 7, the signal from the output of the sixth trigger 7 is fed to the first inputs of the first, second and third elements And 9-10. At the same time, the signal from button 1 Start through the fifth element OR 15 is fed to the input of the unit 1 of the second flip-flop 3 and sets it to the one state, B. As a result, the signal from the direct output of the second flip-flop 3 turns on the drive 32 of the receiving hopper and the load begins to flow into the metering hopper.

As the hopper of the metering unit fills, the lower filling sensor 31 triggers, the signal from which, passing through the ninth 19th and seventh 17 research institute elements, is fed to the input of the first delaying element 21 and the third element OR 13. The output signal from the third element OR 13 enters to the input of the installation in the 1st fifth trigger 6 and sets it to one state, which leads to the activation of the actuator 35. As a result, the weight sensor is removed from the stop of the metering hopper and does not interfere with its movement.

The signal from the filling sensor, delayed by the first delay element 21, sets in one state the third trigger 4, the signal from the output of which arrives at one input 36 of the drive 38 for moving the dosing hopper downward, which causes the latter to move towards the transport capacity and prepare the site. for the arrival of a new portion of cargo in the metering hopper,

The downward movement of the metering hopper continues until the metering movement of the metering hopper is triggered. The signal from the displacement sensor 33 arriving

to the third input of the second element OR 12, sets to the zero state the third trigger 4, which turns off the drive 38 and thereby stops moving down the dosing bin,

At the same time, the signal from the output of the second element OR 2, having passed through the tenth element OR, sets the fifth trigger 6 to the zero state, as a result of which the drive 35 returns the weight sensor to the working position.

Then, the cycle of operation of the device is repeated until the next batch of loads is accumulated in the dispensing bin and the next filling sensor activates.

When the metering hopper is filled with a load, the upper filling sensor 31 is triggered, the signal from which is fed to the input of the first element OR 11. The signal from the output of the element OR 11 sets the second trigger 3 to zero, as a result of which the actuator 32 closes the gate of the receiving hopper.

At the same time, the signal from the upper filling sensor enters the third input of the seventh element of the IPI 17, the signal from the output of the seventh element OR 17, as well as when the previous filling sensors are triggered, triggers the weight sensor drive 35 to move it out of order and to turn on the drive 38 one input 36 to move the dosing hopper down.

In this case, the metering hopper moves downward until the level sensor turns on, which generates a signal when it touches the bottom of the transport tank or the level of the pre-loaded cargo.

The signal from the level sensor sets the first trigger 2 to one 5 state and simultaneously arrives at the first input of the second element OR 12, according to the signal from whose output the third 4 and fifth fifth 6 triggers are set to zero.

The signal from the output of the third trigger 4 is fed to one input 36 of the actuator 38, as a result of which further downward movement of the metering hopper stops.

At a signal from the output of the first trigger 2, the actuator 29 opens the gate of the metering hopper and the cargo is poured into the transport container.

When the fifth trigger 6 is set to the zero state, the weight sensor returns to the initial state.

After unloading the cargo from the bunker-bin to the transport tank, the hopper should return the original

condition. For this, the signal from the level sensor, delayed by the time determined by the fourth element 24, delays the loading process. The control circuit for pressing the sensor and returning the weight sensor to the initial operating state enters the second input of the first element AND 8. However, the signal at the output of the first element And 8 is generated only when the test trigger 7 is in a unit state, which indicates the need to continue the Portion button 45, does not depend on the multiplicity of the number of portions specified for loading the portions of the cargo, the number of portions g capable of being placed in the dose-bunker.

the element OR 18, a-from its output, to the input of the third delay element 23 and to the second input of the third element OR 13. By the signal from the output of the third element OR 13, the fifth trigger 6 is set to one and the drive 35 rejects the weight sensor to an inoperative position.

The delay time of the signal introduced by the fourth delay element 24 is longer than the time it takes for the load to completely drain from the metering hopper.

According to the signal from the output of the third delay element 23, the fourth trigger 5 is set to one, which leads to the inclusion on input 37 of the actuator 38 of moving up the dosing hopper.

At the same time, the signal from the output of the third delay element 23, delayed by the second delay element 22, for the time required to prevent the batch bin from damaging the cargo when closing, sets the first trigger 2 to zero, which causes the gate 29 to close the gate .

The metering hopper is moved upwards by the actuator 38 until the initial state sensor has failed a signal indicating that the metering hopper has returned to its initial state.

These portions of the 45 Portions button do not depend on the multiplicity of the number of portions of cargo specified for loading, the number of portions g capable of being placed in the dose hopper.

The termination of the device in the automatic mode is as follows.

The duration of the device operation depends on the number of portions set for the load, the volume of which is determined by the distance between the filling sensors' ports (if you press 25 that Portion button) or the number of full metering bins (if the Bunker button is pressed).

In the case of setting the number of ports at the output of the third element I, the signals from the output of the sixth trigger 7, the button Portia 45 pressed and the signal from the filling sensors 31 produce a signal arriving at the second input of the sixth element OR 16.

Similarly, the second element AND 9 gives you a signal arriving at the first input of the sixth element OR 16, according to the signal from the output of the sixth trigger 7, and signals from the upper sensor filled and from the pressed button 44 Bunker

The signal is from the code of the sixth element OR. 16 enters the second output of counter 26 and decreases its content by 1.

Thus, as far as loading

At THIS, the signal from sensor 34 of the metering unit and its subsequent

stubs to the input of the fourth element OR 14 and to the input of the tenth element I1Sh 20. As a result, the fourth 5 and fifth 6 trigger, respectively, are set to zero, which causes the actuator 38 to turn off at the upstream movement of the hopper and turn on the actuator 35 to return the weight sensor to the working position.

At the same time, the signal from the initial state sensor, delayed by the fifth delay element 25, is the time required for the hopper to completely stop the loading process. The operation of the control circuit when the pressure sensor is pressed and the weight sensor returns to the initial operating state is fed to the second input of the first element AND 8. However, the signal at the output of the first element AND 8 is generated only when the test trigger 7 is in the single state, which indicates the need to continue the loading process. The operation of the control scheme when pressing

These buttons 45 Portions do not depend on the multiplicity of the number of portions of cargo specified for loading, the number of portions g capable of being placed in the metering bin.

The termination of the device in automatic mode is as follows.

The duration of the device. depends on the number of portions specified for the loading, the volume of which is determined by the distance between adjacent filling sensors (if the Portion button is pressed) or on the number of full dosing bins (if the Bunker button is pressed).

In the case of setting the number of servings. - at the output of the third element I, the signals from the output of the sixth trigger 7, the pressed Portia button 45 and the signals from the filling sensors 31 generate a signal arriving at the second input of the sixth element OR 16.

Similarly, the second element AND 9 generates a signal arriving at the first input of the sixth element OR 16, by the signal from the output of the sixth trigger 7, by the i signals from the upper filling sensor and from the pressed button 44 Bunker.

The signal is from the code of the sixth element OR. 16 enters the second output: the counter 26 and reduces its contents by 1.

Thus, as far as loading

unloading, i.e. during the repetition of the operation cycles of the device, the contents of the counter 26 are reduced.

Upon completion of loading the given

the volume of the load contents of the counter 26 becomes zero. In this case, the signal from the corresponding output of the decoder 27, indicating the performance of the specified work, sets the sixth trigger 7 to zero, the signal from the output of which blocks the passage of signals through the first element 8 and the device to continue operation, after which

the device is automatically terminated.

In the process of loading, the operator can move from the automatic mode of operation of the device to the semi-automatic. To this end, he must turn off the 45 Portion and 44 Bunker buttons and then manipulate the 1, 41, 43 and 42 Start, Stop, Up, Down buttons.

When you press the Start button, the shutter of the receiving bunker opens, as a result of which the bulk load begins to flow into the metering hopper. As the load is filled-in the metering bin, the filling sensors are activated and the drive is switched on to move the metering bin to "nz."

When the level sensor triggers when the bottom of the transport container or the level of the previously loaded cargo is touched, the movement of the dosing hopper stops and its display opens.

After the load is discharged from the metering hopper (within the time determined by the fourth delay element 24), the latter returns to its original state and the gate of the receiver opens. This completes the cycle of operation of the device.

Pressing the button 41 Stop, the operator has the opportunity to close the shutter of the receiving hopper and stop moving the hopper up or down.

When the Down button 42 is pressed, the dosing bin is moved down until the level sensor is triggered.

I will act on the button 43 Up, the operator moves up the bunker and with a delay determined by the second element of delay 22, closes the gate of the bunker.

During operation, the operator can determine the weight of the load accumulated in the metering hopper by measuring instrument 40 connected to the weight sensor 39.
