This invention relates to a continuous lifter for traveling bogies.

[Prior Art] In factories and the like, it is common practice to transfer objects by utilizing the extra space near the ceiling.

Then, for example, a traveling cart supporting an object to be transferred is carried into the factory by running on rails arranged on the ceiling side, and lowered onto rails arranged on the floor side of a production line, etc. Conventionally, in order to lift it from the ceiling to the ceiling rail and carry it out,
An elevator was used to move up and down.

When the traveling carriage supporting the object to be transferred is transferred between the two rails using this elevator, it is carried out as follows.

For example, when moving a cart from a ceiling rail to a floor rail, an elevator is raised to the ceiling rail, the cart is mounted in the elevator, the elevator is lowered to the floor rail, and the cart is moved to the floor rail.

When transferring multiple carts that are continuously flowing, the elevator is equipped with a running cart on the ceiling side rail, descends to the floor side rail, transfers the running cart to this floor side rail, rises again, and performs the above-mentioned process. Repeat the process.

When moving the cart from the floor rail to the ceiling rail, the above steps are performed in reverse.

[Problems to be solved by the invention] By the way, in the case of the above-mentioned elevator, when a plurality of traveling carts supporting objects to be transported are continuously transferred, the elevator equipped with the traveling carts is Other objects to be transferred had to be kept on standby until the truck was replaced and returned to the original rail, making it impossible to quickly transfer the objects.

This invention was made in consideration of the above circumstances,
The purpose is to provide a continuous lifter for a rail running truck that can quickly change the conveyance line of objects to be transferred without interfering with the smooth flow of conveyance of objects to be transferred.

[Means for Solving the Problems] In order to solve the above problems, the present invention proposes two
In a continuous lifter for rail running bogies that is used to replace running bogies suspended between two running rails, a single ring is attached to a frame installed so as to surround the running rails so that its axis is horizontal. The ring is rotatably supported as shown in FIG. However, the rail missing portion of the predetermined length is formed so that the moving rail is fitted into each of the two traveling rails.

[Operation] According to the above configuration, by rotating the ring and sequentially fitting the movable rail into the missing rail portion of each traveling rail, the flow continuously flows on one of the upper and lower traveling rails. It is possible to quickly transfer the moving bogie to the other running rail.

[Example] An example of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view showing a continuous lifter for a rail traveling bogie according to the present invention, and FIG. 2 is a side view of FIG. 1.

In the figure, numeral 1 is a ceiling-side running rail installed on the ceiling of a building, etc., and 2 is a floor-side running rail for transporting objects 3 to a manufacturing line or the like. Reference numeral 4 denotes a continuous lifter for a rail running bogie according to the present invention, and by this lifter 4, the running bogie 5 supporting the transferred object 3 is moved from the ceiling side running rail 1 to the floor side running rail 2 or from the floor side running rail. 2 to the ceiling side traveling rail 1. In addition, in the vicinity where the continuous lifter 4 for rail running bogies is located, 2
The two running rails 1 and 2 are provided parallel to each other and on the same perpendicular line.

The continuous lifter 4 for rail traveling bogies is configured as follows.

A pedestal 6 is provided so as to surround the two running rails 1 and 2, and a ring 7 is rotatably supported within the pedestal 6 by support rollers 8, 9, and 10. This ring 7 has a diameter equal to the distance between the two running rails 1 and 2, and its center is on a perpendicular line that includes the two running rails 1 and 2, and is lower than the midpoint of the two running rails 1 and 2. It is located above. The support roller 10 is driven by a servo motor 1 for rotationally driving the ring 7.
1 is connected. Further, the ring 7 has two support shafts 12 and 13 extending parallel to the traveling rails 1 and 2 at positions facing each other and shifted by 180 degrees.
Arms 14 and 15 are rotatably supported on support shafts 12 and 13, respectively. Moving rails 16 and 17 are attached to the arms 14 and 15. The lengths of the arms 14 and 15 are set so that when the ring 7 rotates and the moving rails 16 and 17 are located on the same perpendicular line, they match the positions of the two traveling rails 1 and 2,
For this reason, the two traveling rails 1 and 2 are provided with rail missing parts 18 and 19 in which the portions where the moving rails 16 and 17 are located are removed. In other words,
The two running rails 1 and 2 are moving rails 16 and 17
1a, 1b and 2a, respectively in the parts where are located.
2b, and in order to connect them, moving rails 16, 17 are installed in the rail missing parts 18, 19.
are designed to fit together. Note that the traveling trolley 5 is self-propelled, and cables (not shown) are connected to the ceiling traveling rail 1, the floor traveling rail 2, and the moving rails 16 and 17 for supplying electric power to the traveling trolley 5.
is installed. Furthermore, moving rails 16, 17
Since the above-mentioned cable is connected to the ring 7, the ring 7 is configured to rotate 180 degrees from side to side.
A ring rotation drive control device 20 is connected to the servo motor 11 to control the servo motor 11 that rotates the ring 7 by 180 degrees left and right.

Next, the action will be explained.

A large number of objects 3 are transported on the ceiling traveling rail 1 1a.
When the object is transported from the side and is continuously transported to the 2b side of the floor-side traveling rail 2, the first traveling cart 5 supporting the transferred object 3 is moved from the 1a side of the ceiling-side traveling rail 1. Come and move rail 16
When the ring 7 stops, the ring 7 is rotated, for example, 180° to the right by the servo motor 11 controlled by the ring rotation drive control device 20. As a result, the movable rail 16 is moved to the rail missing portion 1 of the floor side traveling rail 2.
9 and connected to this traveling rail 2, the first traveling carriage 5 moves toward the 2b side of the floor-side traveling rail 2. At this time, the moving rail 17 is fitted into the rail missing part 18 of the ceiling side traveling rail 1,
The second traveling carriage 5 is moving to this moving rail 17.

Next, the ring 7 is rotated 180° to the left, and the moving rail 17 fits into the rail missing portion 19 of the floor-side traveling rail 2. Then, the second traveling carriage 5 moves toward the 2b side of the floor-side traveling rail 2. At this time, the third traveling carriage 5 is moving on the moving rail 16 that is fitted into the rail missing portion 18 of the ceiling side traveling rail 1, and the ring 7 is rotated 180 degrees to the right.

By repeating the above steps, the traveling carts 5 continuously flowing on the ceiling side traveling rail 1 are transferred to the floor side traveling rail 2 one after another without stopping this flow.

When transferring the object 3 from the 2a side of the floor side traveling rail 2 to the 1b side of the ceiling side traveling rail 1, the traveling trolley 5 moves from the floor side traveling rail 2 to the ceiling side traveling rail 1 side by the moving rails 16 and 17. The rest of the steps are similar to those described above.

In addition, the object 3 to be transferred is
From the a side to the 1b side or the floor side traveling rail 2 of 2
When flowing from side a to side 2b, move rail 16,
The ring 7 is fixed in a state in which the ring 17 is fitted into the rail missing parts 18 and 19 of the ceiling side running rail 1 and the floor side running rail 2, respectively.

As described above, since the traveling carts 5 supporting the objects 3 to be transferred are replaced one after another by the two moving rails 16 and 17, the conveyance line for the objects 3 to be transferred is maintained without interfering with the smooth conveyance flow of the objects 3 to be transferred. can be changed quickly.

[Effects of the invention] In summary, the invention provides the following effects.

(1) Since the moving rail is rotatably supported on a pair of support shafts extending from the rotatable ring end face,
