(54) INSTALLATION FOR PNEUMATIC CARGO TRANSPORTATION IN CONTAINERS OR CONTAINER COMPOSITIONS

The installation contains terminal stations 1 and 2, which through segments 3 turnouts 4 are connected by two main pipelines .5 and. Near the stations 1 and 2 there are tin blower stations 7, which are connected to pipelines and 6 through valve 8, and to stations 1 and 2 - through valves 9. The installation will also contain intermediate air-treatment stations 10. At stations 11 that are calculated with valves, pipelines 5 and 6 incorporate sluice devices consisting of a pipe section 12, the length of which is determined by the length of the composition and the area of its braking in the sluice device, and sluice gates 13 and 14, allowing the compositions to pass freely in the open position. Transport pipelines communicate with at1 ") the sphere by nozzles 15. The gaps between adjacent blower stations (for example, and 10) are divided into control areas bypass devices so that no more than one container composition can be located at each control section.

Bypass devices are made of a section 16 of a bypass pipe connected in parallel to the transport pipeline, with a valve 17 installed on it. At the inlets and outlets of the bypass sections, the position sensors 18 and 19 are installed (passing), the position position sensors 20, and at the exit of the switches, sensors 21 of the position of the trains. Inside the sluice device, the composition position sensor 22 is installed at a distance of the composition from the first along the movement of the sluice gate 14, and the composition position sensors 23 are installed at the distance of the composition from the switches 4.

the outputs of the sensors 18-23 are connected respectively to the inputs of the local control units 24-26 (see FIG. 2) connected by their outputs with the inputs of the respective local execution devices 27-29.

The actuator 27 is connected to the actuator 30 of the valve 17 of the bypass device with a position sensor 31.

Actuator 28 is associated with actuators 32 and 33 with position sensors 34 and 35, actuator1 "1 36 and 37 sluice gates with sensors 38 and 39 position and 40 actuator valves of air nozzles embedded at the end of the loading and unloading station and near the sluice gate , with 41 position sensor.

The actuator 29 is connected to an arrow actuator 42 with its position sensor 43, with actuators.

44 and 45 valves 8 and 9 with their sensors 46 and 47 position and actuator; 40 with sensor 41 position.

On terminal and intermediate stations (see pos. 1, 2, 10 in Fig. 1), besides, blocks 48 are installed for monitoring and correcting time intervals of movement between trains, which are connected to sensors 21 or 20 of trains and local units 25 and 26 of the control.

Block 48 (see fig. 3) consists of a time relay 49 connected to the output of the sensor, for example, 20, the position of the capacitors, the generator 50 of single pulses connected through

Open contact 49.1 of the relay 49 to one of the inputs of the trigger 51, the other input of which is connected to one of the inputs of the second trigger 52 and through the delay element S3 to the output of the logic element 54, which is the output of the block 48.

The inputs of the element 54 are connected respectively to the output of another element And 55, connected by its inputs to the outputs of both triggers 51 and

52 and to the output of the element OR 56, the input

which, via delay elements 57 and 58, are associated respectively with the output of block 25 (or 26) and with the output of generator 50, the output signal from block 25 (or 26) is also fed to another input of trigger 52.

The installation works as follows.

5 The actuators of the head and intermediate blower stations 7 and 10 are switched on. In the absence of compositions, the installation takes the initial position, in which the valves 17 on the bypass sections are closed, the sluice devices are in the Intake position, i.e. the lock gate 14 is open, the valve 11 is closed, the valve 9 is open, the lock gate 13 is closed, the valve (not shown in the drawings) in the bypass pipe behind the gate 13 is closed.

The switches 4 are installed in the position on Reception of the composition in terminal (loading and unloading) stations 1 and 2. The composition is introduced into station 1 by a special device (not shown in the drawings). The automation unit at the discharge station (not shown in the drawings) signals the local control unit 26 that the train is ready for launch. When a signal is received from the local control unit 24 by the bypass device via the communication line, that the control section is free, the local control block 26 is sent to the input of the control and correction unit 48 to signal the technological readiness of the train to start. The other input of block 48 receives a signal received from the impact of the previous composition on sensor 21 (see Fig. 1) located at the output of terminal station 2. After the arrival of this signal after a time not less than the specified time ut, the control and correction unit 48 will output the signal to the local control unit 26 permits the train to start up and returns to its original state. The control unit 26 through the local actuator 29 will start the train from station 2.

The launched train, leaving station 2 and affecting sensor 21, the signal from which will again start the control and correction unit 48, moves along the main pipeline 6 and, upon entering the bypass device, acts on sensor 18 (see Fig. 1 and 2), the signal from which arrives at the local control unit 24 and is memorized. If, up to this point, the local control unit 24 on the communication line from the local control unit 24 of the next bypass device (not shown) does not receive a signal from the previous composition on the sensor 19, then the local control unit 24 sends the first bypass device command to the local actuator 27, which includes the actuator 30 of the valve 17 and opens it. As soon as the local control unit 24 receives such a signal, it will issue a command to the actuator 27, which turns on the actuator 30 of the valve 17 and closes it. If by the time the signal was generated by the sensor 18 located at the input of the first bypass device, the signal from the sensor 19 located at the exit of the bypass device following the direction of movement was received, then the first bypass device remains in its original state open for movement.

The exit from the bypass device, the composition acts on the sensor 19 for passing the composition, the signal from which is sent to the local control unit 24 from the output of which, via a line "to the input to the local control unit 26, receives a signal that the control section is free, and from station 2 The next lineup is launched.

When the first train enters the lock device, the position sensor 22 triggers and sends a signal to the local control unit 25, which

in the absence of a compound in front of the sensor 19, the position in the control section of the pipeline 6 generates a signal to the local actuator 29 to switch the air distribution valves to the position of starting the train, after which the signals from the corresponding sensors through the local actuator 28 act on the unit 25 block 48 control and

O correction of the technological readiness of the composition to exit the lock device. After a period of time not less than d1, after the arrival of this signal, block 48 will generate a signal

5 to the local control unit 25, which, in turn, gives the command to the local HjC complete device 28 to close the valve installed behind the sluice gate 13. This

The 0 signal will then return block 48 to its original state.

When leaving the lock device, the composition acts on the sensor 20, the signal from which enters the field. The control unit 25, which, together with the local executive device 28, prepares the sluice device for the next train. Thereafter, at the output of the local control unit 25, a signal appears.

0 pals that the control area is free. This signal on the communication line arrives at the local control unit 24 of the bypass device.
