SU516252A1 - Container handling station for a pneumatic pipeline transportation system - Google Patents

Description

The invention relates to a pneumatic tubing container transport, namely, a station for stopping a container train or for single NELH containers. The container station is known to have a pneumatic conveying pipe installation containing a brake chamber with a bypass line, a sluice gate and a container position sensor. The aim of the invention is to accurately stop the containers at a given current and reduce the size of the station. This is achieved by the fact that the proposed station is equipped with two outlets to the atmosphere, connected to the main station at a distance from each other that is not for containers, but is connected to the bypass line from the blower station and in both branches and bypass line from two Shut-off dampers are installed on the sides of the duct connection, connected to a control device connected to the container position sensor. The drawing shows the proposed station. Line 1 is connected to the atmosphere by taps 2 and 3, in which shut-off control valves 4 and 5 are installed with actuators 6 and 7, with the edges of taps 2 and 3 nearest to each other located at a distance equal to the length of train 8. In the stop zone The structure 8 has a sensor 9, for example a reed switch, interacting with a magnet 10 fixed on one of the containers 11 of the composition 8. The output of the sensor 9 is connected to the input of the control unit 12, which is a logic circuit. To one end of the brake chamber 13, which is a continuation of line 1, is connected to the outlet of the duct 14, equipped with a shut-off valve 15, driven by an actuator 16. The second outlet of the duct 14, equipped with a shut-off regulator valve 17, driven by an actuator 1B, is connected to the highway 1 before entering the stop zone in the direction of travel of the train. Both outlets of the duct 14 form a bypass line 19, which can be used to bypass the carrier gas if the station is intermediate. In front of the station in line 1, a gateway 20 with an actuating mechanism 21 is installed before connecting the bypass line.

The actuators 6, 7, 16, 18 and 21 are connected to the outputs of the control unit 12, which performs 5shutting off the flaps depending on the input information received from the sensor 9.

The station operates as follows.

Before receiving the containers, the gateway 20 is open and the shutters 4, 5, 15 and 17 are closed.

Pneumatic 8 through inertia 1 (the atmospheric line on line 1 is not shown in the drawing, which is located near the end point and is always open when the train 8 moves to the stop point) enters the station. When the train passes with the magnet 10 installed on it, the sensor 9 installation points out a signal to the control unit 12 that the train 8 passes. The control unit 12 orders the signals of the following sequence: in nepBsw, the valve 15 opens, resulting in compressed air entering the chamber 13 movements of pneumoabout - the braking mode begins.

After a certain time interval, the signal formed by the control unit 12 opens the dampers 4 and 5 simultaneously. In this case, the taps 2 and 3 communicate with the atmosphere, and then the shut-off valve 17 opens.

The compressed air flow branches along the outlets of the duct 14, and since the outlet 3 is in communication with the atmosphere, the compressed air presses behind the composition with less force. By the force of the air flow in the chamber 13, the pneumatic composition 8 begins to shift to the right side. In block 12 control input data from the sensor

9, a signal is generated by the sign of movement, as a result of which the position of the shut-off damper 17 is adjusted and the forces of air flow are balanced on both sides of the pneumatic composition 8, which is in the exact stop zone, for example, under the hoppers 22. Cross section atmosphere, equal to half the cross section of the duct 14. Such a ratio of pipe sections allows you to get rid of the duration of the transition (oscillatory) process and in a short period of time makes a complete stop of the pneumatic composition 8 in tr buoy zone.

The stationary state of the pneumatic composition is signaled by the sensor 9, on the basis of which the flaps 17 and 15 simultaneously overlap; the pneumatic composition is in a stationary state.

The proposed station provides efficient, accurate stopping of containers without hydro-mechanical brake assemblies.
