Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes forced airflow or the like as a propulsion force to move a load carrying cart along the transfer pipe, thereby transporting the cargo within the transfer pipe in an intra-pipe transfer device for transporting cargo. The present invention relates to an unloading device for an intra-pipe transfer device that accepts a transport cart moving along a transfer pipe midway through the transfer pipe and unloads the cargo.

Especially when the cargo is powdery material such as earth, sand, cement, etc.
When unloading the cargo, it is most advantageous mechanically and in terms of efficiency to invert the cart and drop it in, but the conventional unloading devices have the following problems. There was a point.

In other words, in the unloading device of such an intra-pipe transfer device, it is necessary to carry out the cart from a predetermined transfer pipe, and after unloading, carry it in again. However, in conventional equipment, a mechanism for transferring the trolley between the two pipelines and a mechanism for carrying out the unloading operation are provided separately, and both operations are performed separately. This not only made the mechanism more complicated, but also required the process of receiving and passing the trolley between the two mechanisms, and although it was a drop-in type of unloading work, it was difficult to see from the overall unloading work. This required a considerable amount of work time and was inefficient.

In view of this, the present invention aims to combine unloading work using a drop-in method with work for transferring cargo onto a trolley, thereby making it possible to perform unloading work very rationally and efficiently. It is something.

The unloading device for an intra-pipe conveyance device of the present invention is an unloading device for an intra-pipe conveyance device that receives a transport cart moving along the transfer conduit midway through the transfer conduit and unloads the cargo. , a plurality of conduits for receiving and discharging cargo carriers are formed with an opening at the top of each conduit, and are arranged in parallel with each other at appropriate intervals, and these conduits are A conduit revolution mechanism is provided in which the conduits are integrally rotated around an axis in the longitudinal direction provided at a central position between each conduit, and the positions can be interchanged. A conduit rotation mechanism is provided to rotate each conduit around its center so that the opening thereof faces downward when the conduit revolves, and the lower part of the revolution path of the conduit is The cargo receiving device is characterized in that it is equipped with a device.

In other words, by rotating a plurality of conduits around their respective centers and revolving around the central axis between each conduit, the positions of the conduits are exchanged with each other, and the carriage moves from the receiving position to the delivery position. At the same time as the transfer is carried out, during the transfer, the trolley is reversed along with the conduit, and the cargo can be dropped and discharged through the opening at once.

Therefore, according to the present invention, the unloading operation consisting of the two steps described above can be carried out continuously by simply rotating both pipes, and
This can be done reliably, improving the efficiency of unloading work.Moreover, when moving by traversing a pipe, for example, the time for moving the pipe later must be included in the unloading work time, but the unloading work efficiency is improved. By revolving the pipelines as one, they exchange positions with each other, so the unloading time is reduced to the time it takes to move one pipeline to the other. The time required for unloading work is extremely short.

In addition, it is possible to unload cargo at the same time while the transport carts are exchanging positions for receiving and sending out (during revolution of the pipeline).
There is no need for a separate space for unloading on a plane (this results in an advantageous arrangement of the entire device).

Next, embodiments will be described based on the drawings.

FIG. 1 shows an intra-pipe transfer device, in which transfer pipes A and B are arranged parallel to each other at appropriate intervals, and PA and PB are arranged in opposite directions in the transfer pipes A and B. 4 is a pump that generates an airflow that flows in the direction; 4 is a cargo carrier that moves along the transfer pipes A and B by receiving the airflow and using it as a propulsion force; , B is an unloading device configured at the end of the cargo transport direction, and performs unloading work on the cart 4 moving along one transfer pipe A, and unloads the cart 4 after unloading. is configured to be moved through the other transfer pipe B.

Figures 2 and 3 A and 3 show the trolley 4, which is

In the figure, 4a is a lid that swings open and close the cargo loading section 4A, and due to its weight, it is in the closed position when the trolley 4 is in the normal position, and when the trolley 4 is in the inverted position. It is configured to be in an open position.

Moreover, this truck 4 is used in a three-tube connected state.

FIG. 4, FIG. 5, FIG. 6, and FIG. 7 show the unloading device C.
1A and IB are the transfer pipe A.

A bogie receiving conduit and a delivery conduit are arranged parallel to each other at appropriate intervals, and these connect to the three-car connected bogie 4. The trolley 4 is long enough to be stored inside and is located inside.
. . . has openings 1a, 1b . . . on the upper part corresponding to the lid 4a . And its center a.

They are relatively connected via a frame F in a state where they can freely rotate around 5.

2 is the pipe IA around the axis 0 in the longitudinal direction of the pipe at a central position between the pipes IA and IB.

1B is integrally rotated to reversibly switch the connection state of the pipes IA and 1B to the transfer pipes A and B (a pipe revolution mechanism is provided, which is driven by the motor 2A to rotate the pipes IA and 1B together). The receiving pipe 1A or 1B, which connects the frame F to the transfer pipe A through the two sprocket wheels 2B, 2B and the transmission chain 2C, rotates in one direction around the axis 0 to move along the lower revolving path. It is something to do.
