Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyance facility using an elevator.

When a self-propelled trolley transports cargo between the inside and outside of the elevator, the self-propelled trolley must always be reciprocated along a fixed path to prevent it from colliding with the elevator's elevating body. It has to run. For this purpose, in the past, guide rails and the like were buried or grooves were cut in each floor surface and the floor surface of the elevator. However, in this case, large-scale construction work is required on the floor surface, and furthermore, the guide rails and grooves constructed on each floor surface make it impossible for other traveling bodies to run smoothly.

The purpose of the present invention is to make it possible for a self-propelled cart to always travel back and forth on a fixed path while making each floor surface and the floor surface of the elevator body flat, and to form the elevator body so that no wasted space is created. The purpose of the present invention is to provide a transportation facility that can utilize an elevator.

In order to achieve this object, the conveyance equipment using an elevator of the present invention is configured such that a self-propelled cart having a cargo receiving platform that can be raised and lowered on the upper part is configured to be able to run between the floor and the elevating body of the elevator. A telescopic guide body is disposed between the front end of the truck and the rear wall of the elevating body, and the end of a cable that can be fed out from the elevating body is connected to the self-propelled truck.

According to this configuration of the present invention, the self-propelled vehicle can be run on an integrated route by the expansion and contraction guidance of the guide body disposed between the self-propelled vehicle and the elevating body, and furthermore, both floor surfaces can be made flat. . Furthermore, when the self-propelled trolley is positioned inside the elevating body, most of the deflated guide body is stored inside the self-propelled trolley, and the traveling of the self-propelled trolley and the lifting and lowering of the loading platform are carried out via cables. This can be done using signals or power supply.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIGS. 1, 4 to 6, 1 is a self-propelled trolley, which includes a main body 2, a load receiving platform 3 attached to the upper part of the main body 2 so as to be able to rise and fall, and wheels 4 attached to the lower part of the main body 2. Consisting of An elevating drive motor 5 is disposed on one side of the main body 2, and a pair of left and right eccentric cams 8 are connected to a rear transverse shaft 7 which is interlocked and connected to the elevating drive motor 5 via a winding transmission mechanism 6. At the same time, a pair of left and right eccentric cams 11 are attached to a front transverse shaft 10 which is interlocked and connected to the rear transverse shaft 7 via a winding transmission mechanism 9. And each eccentric cam 8, 11
Cam rollers 12 and 13 are attached to the load receiving platform 3 side so as to come into contact with the load receiving platform 3 from above. Therefore, by rotating both horizontal shafts 7 and 10 in the same direction by the lifting drive motor 5, the loading platform 3 can be lifted and lowered by the rotating eccentric cams 8 and 11 via the cam rollers 12 and 13. A running drive motor 14 is disposed on the other side of the main body 2, and this running drive motor 14 is interlocked and connected to the wheel shaft of the wheel 4 via a winding transmission mechanism 15. Therefore, by driving the traveling drive motor 14 in forward and reverse directions, the self-propelled trolley 1
can be run back and forth. A through hole 16 is formed in the rear wall of the main body 2, and a telescopic guide body 17 is disposed through the through hole 16 and a large part of the guide body 17 can be stored inside the main body 2. Although the guide body 17 is of a four-stage telescopic type in the embodiment, the number of stages is not limited. The small-diameter end of the guide body 17 is connected to the front end of the main body 2 via a pin 18, and the large-diameter end is fixed to the rear wall 21 of the elevating body 20 of the elevator 19. Therefore, the self-propelled trolley 1 has the position of the elevating body 20 on the elevating body floor surface 22 when the guide body 17 is contracted, and the first floor 23 or the second floor 24 (or more floors) where the guide body 17 is extended. It becomes possible to travel on a fixed route between the positions on the floor surface 25. The elevator 19 is the elevating body 20
It is composed of an elevating path 26 for the elevating body 20, an elevating wire rope 27, communication paths 28, 29 corresponding to the floors 23, 24, and the like. A reel 30 is provided near the rear wall 21 of the elevating body 20,
Cable 31 wound on this reel 30 and fed out
The end portion of is connected to the self-propelled trolley 1. This cable 31 is a collection of power supply lines, signal lines, and the like. The load 32 is placed on a wagon 33.

In the solid line in FIG.
A wagon 33 carrying a load 32 is stopped at a fixed position on the floor 25 of the second floor 24 corresponding to number 0. In order to transfer the wagon 33 to the first floor 23 from this state, first the self-propelled trolley 1 formed by lowering the loading platform 3 is advanced and positioned at the lower part of the wagon 33 as shown by the imaginary line in FIG. 1 from this elevating body floor surface 22
When moving forward toward the floor surface 25, the guide body 17 gradually extends, and the self-propelled cart 1 is guided by the guide body 17 and moves forward on a fixed path. With the self-propelled cart 1 positioned below the wagon 33, the load receiving platform 3 is raised, and the load 32 is lifted up through the wagon 33 as shown by the solid line in FIG. Next, the self-propelled cart 1 is moved backward, and the wagon 33 is pulled into the elevating body 20 as shown by the imaginary line in FIG. During this backward movement, the guide body 17 gradually contracts, and the self-propelled cart 1 is guided by the guide body 17 and moves backward on a fixed path. The cable 31 is automatically wound onto the reel 30 when moving backward. Thereafter, the elevator 19 is operated, and the elevator 20 is moved to the first floor 23 as shown by the solid line in FIG. Then, the self-propelled trolley 1 is advanced to move the wagon 33 to a fixed position on the first floor 23 as shown by the imaginary line in FIG. After that, the self-propelled trolley 1 is moved backward into the elevating body 20. Thereafter, the elevating body 20 is raised to correspond to the second floor 24, thereby returning to the state shown by the solid line in FIG. 1 again.

By performing the opposite operation to the above, the first floor
3 wagons 33 can be moved to the second floor 24. The traveling of the self-propelled trolley 1 and the raising and lowering of the loading platform 3 are performed by operating a control section provided in the elevating body 20 and by signals via a cable 31. Further, in the embodiment, a format in which the cargo 32 is handled via the wagon 33 is shown, but this is a format in which the terminal end of the conveyor or a fixed frame is arranged at a fixed position on each floor 23, 24, and the cargo 32 is handled directly. You can. Furthermore, guide body 1
7 may be arranged with its large diameter end fixed to the main body 2.

According to the present invention having the above configuration, the self-propelled trolley can be made to reciprocate on a fixed route by the telescopic guidance of the guide body disposed between the self-propelled trolley and the elevating body of the elevator, and only by providing the guide body. The structure can be simplified because it can be done easily. Furthermore, since the floor surface of the elevator and each floor surface can be made flat, large-scale construction work is not required, and since each floor surface is flat, other traveling objects can run smoothly.
Moreover, when the self-propelled trolley is positioned inside the elevating body, the guide body contracts and most of it is stored inside the self-propelled dolly, so there is almost no space for the guide body in the elevating body. It can be formed so that no wasted space is created. Further, the running of the self-propelled cart and the lifting and lowering of the loading platform can be reliably performed by control from the lifting body side using signals and power supply via the cable.
