Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an intra-pipe transport device using forced air flow, which is configured to propel a transport vehicle along the pipe pipe using forced air flow as a propulsion force. In order to safely transport a cart that has been moving at high speed into a loading section or an unloading section configured at a location, a cart stopping and sending device is configured to safely stop the cart using an air cushion and then send it out at a safe speed. Regarding.

Conventionally, a valve that can be opened and closed is provided in the pipeline, and by closing the valve, the moving trolley is safely stopped using an air cushion, and after stopping, the valve is opened. Since the trolley was sent out using the airflow for transporting the trolley in the pipeline, it was possible to safely stop the trolley, but since the transporting airflow was used to send out the trolley, it was not possible to control the delivery speed and send out the trolley safely. For example, if the conveyance interval between carts is narrow, if the valve is opened after the stopped cart is sent out, there is a risk that the following cart will be sent out at the same speed without stopping. There is a drawback in that stopping and then sending out the carts, such as adjusting the cart transportation intervals to match the needs of the carts, imposes restrictions on the transporting action of the intra-pipe transport device.

Therefore, there is an additional valve (hereinafter referred to as the first valve and the second valve) located on the upper side of the conveyance from the valve at a distance sufficiently far from the front and back length of the truck.

) to operate in opposition to the second valve, and a delivery device such as a pusher conveyor that engages and moves a cart such as a pusher conveyor is installed in the pipe line between these valves to close the second valve (to close the first valve). After that, the first valve is closed (the second valve is opened) to prevent the transport airflow from flowing into the pipe section. There is also a structure that prevents migration and sends out the following truck in a state where it can be safely stopped using an air cushion.

However, in this case, the first valve allows the carriage to be sent out at the desired speed without being affected by the conveying airflow, and is closed even when the second valve is opened for sending out, so that the conduit section of the following carriage is This allows the trolley to be stopped once and sent out without fail, and the transporting action of the in-pipe transport device is sufficiently ensured to allow the cart to be sent out safely. However, since the feeding is carried out by abutting and engaging a pusher or the like with the cart, there is a drawback that the structure of the cart is restricted and the structure of the pipe section cannot be avoided.

In view of the above points, the present invention effectively utilizes the propulsion function of the bogie, which is configured to be propelled by forced airflow in the conduit, to improve the structure of the bogie and improve the structure of the conduit. The purpose of the present invention is to provide a bogie stopping and sending device for an intra-pipe conveyance device that utilizes forced airflow, which can rationally and functionally stop and send out the bogie without causing any damage.

Next, embodiments of the present invention will be described based on FIGS. 1 to 6.

Reference numeral 1.1' indicates two parallel pipes in which forced air flows in opposite directions are generated, and reference numeral 2 indicates the pipes using the forced air flows in the pipes 1 and 1' as a driving force. It is a transport vehicle configured to move along the inside of pipes 1 and 1', and has a group of running wheels 2a that come into sliding contact with the inner surfaces of pipes 1 and 1', and a plate 2b that receives forced air flow. They are placed in the front and back.

MP is a strong dielectric u provided at one end of the group of pipes 1 and 1'.
A main pump for generating air flow, which is connected to one pipe 1
Air is sucked in from near one end of the pipe, and this sucked air is sucked into the other pipe 1'. 1 is configured to blow air sucked in from inside 1 into one of the pipes 1, thereby generating forced air flows in opposite directions within both pipes 1 and 1'. It is.

3A and 3B are terminal parts located on the downstream side of the air suction port 4' of the main pump MP of the one pipe line 1,
A first valve and a second valve are provided at three locations spaced apart from each other by a distance sufficiently longer than the length of the front and back of the truck 20, and these valves are used to cross and block the return pipeline 1 in order to stop the truck 2 using an air cushion. It is constructed so that it can be slid freely between a closed position that allows the carriage 2 to pass through, and an open position that allows the passage of the trolley 2, and is linked to open and close in a contradictory manner.

4 is the double valve 3A. The opening is close to the first valve 3A in the pipe section between 3B and 3B, and is connected to the auxiliary pump AP that operates in conjunction with the opening operation of the second valve 3B. When the second valve 3B is opened, an auxiliary forced air flow is blown into the truck 2 in the conduit section 1A, which has been stopped due to the closing of the second valve 3B.

Reference numeral 5 denotes a take-out route connected to the terminal end of the one pipe line 1 in order to move the cart 2 downward in an open state to the atmosphere, and 6 indicates a hydraulic cylinder I connected to the take-out route 5 and the starting end of the other pipe line 1/.
A half-cylindrical working pipe 8 in a horizontal position that can be selectively connected via a traverse mechanism is located above the traverse path of the working pipe 6 and is connected to the empty truck 2 on the working pipe 6. A hopper 9 is provided to allow the cargo to be dropped and supplied; 9 is a trolley booster provided to ensure that the trolley 2 of the work tube 6 is moved out from the take-out path 5; A stopper 11 using a shock absorber and stopping at a fixed position in the working pipe 6 is a pushing tool using a cylinder, which is provided to push the cart 2 from the working pipe 6 to the other pipe line 1'.

Reference numeral 012 denotes an on-off valve that is opened only when the truck 2 is transferred to prevent the intake air from escaping from the opening at the starting end of the other pipe line 1'.

According to the above configuration, by closing the second valve 3B,
By stopping the cart 2 moving in one of the pipes 1 within the pipe section 1 with an air cushion, opening the second valve 3B, and blowing an auxiliary forced air flow from the port 4,
This stopped cart 2 is sent out to the takeout route 5,
At the time of this delivery, the first valve 3A is in the closed position, thereby preventing the forced airflow in the pipe line 1 from entering the pipe line part 1, and also transporting the moving cart 2 into the pipe line part 1.
The air cushion stops before point A.

When the first valve 3A is opened, this stop truck 2 is moved into the conduit section by a forced air flow.

As described above in detail, the truck stopping and sending device in the intra-pipe conveyance device using forced air flow according to the present invention safely stops the truck 2 with an air cushion by using the two valves 3A and 3B that open and close in reverse. When the cart 2 located within the pipe section 1 is sent out, the following valve 3A reliably prevents the following cart 2 from moving into the pipe section 1A in a state where it can be stopped safely. The carriage 2 is sent out by blowing auxiliary forced airflow through an opening 4 provided in one of the conduit sections.

Therefore, according to the present invention, since the cart 2 that has been safely stopped in the pipe section 1A is sent out by air current, there is no need for structural improvement of the cart 2, and the structural improvement of one pipe section can be carried out at the port 4. Although it is only a very simple addition to the structure, such as providing a
The trolley 2 can be safely sent out at a desired speed.

As a result, the present invention adopts the means of providing two valves 2A and 2B, and allows the carriage 2 to be stopped and sent out safely and reliably while sufficiently ensuring the conveying action of the intra-pipe conveying device. It has now become possible to provide a bogie stop and delivery device for an intra-pipe conveyance device that utilizes forced airflow and has a simple structure.
