2. Description of the Related Art A moving partition is constructed so that it can be pulled out from a storage part in order to partition a large space into a smaller space. A traveling rail is arranged on the ceiling, and a suspension vehicle attached to the upper end of the partition is used for the above traveling. It is installed on rails and rolls. Such moving partitions include a cross traveling type moving partition and a curve traveling type moving partition depending on the form of the traveling rail arranged on the ceiling. In the former partition, the traveling rails intersect in a cross shape or a T shape. On the other hand, the latter partition uses curved rails. Of course, each has advantages and disadvantages, and it is only necessary to use an appropriate one according to the application, but the present invention is intended for the latter curve traveling type moving partition, and FIG. The outline of a curved traveling type moving partition is shown.

By the way, the curved traveling type moving partition shown in the figure has two storages, and the partition stored in the storages is pulled out to partition a predetermined room space. Therefore, each storage rail (b), (b) ... branches off from the drawer rail (a), and the storage rail
Moving panels (c), (c) ... are hung from (b) and (b). Here, a branch block is provided at the portion B between the drawer rail (a) and the storage rail (b). In the curve type moving partition, each moving panel (C),
(C) The location where ... is stored is predetermined, and a predetermined suspension vehicle will not enter the other storage rail (b).

A partition rail (d) is continuous with the drawer rail (a), and the moving panels (c), (c) ... Are arranged along the partition rail (d). FIG. 4 shows a suspension vehicle installed in a branch block B between the drawer rail (a) and the storage rail (b). As shown in the figure, a guide block (e) is fixed to the ceiling of the rail, and a guide roller (f) is attached to the upper part of the suspension vehicle. The guide roller (f) hits the guide block (e) to determine the traveling direction of the suspension vehicle, that is, the storage rail (b) into which the suspension vehicle enters. Therefore, the guide block (e) in each branch block B
And the height of the guide roller (f) of each suspension car is adjusted.

Although a large room is partitioned by the curved traveling type moving partition shown in FIG. 3, there are only one partition method. However, in reality, as shown in FIG. 5, it is desired to change the size of the partitioned room. Therefore, there are three partition rails (g), (h) and (ri) on the ceiling rail of the room. However, in the structure of the suspension vehicle or rail shown in FIG.
A suspension vehicle cannot enter by freely selecting (G), (H), or (R).

Therefore, even in such a curved traveling type moving partition, a partition rail is selected and the moving panel is selected.
As conventional examples capable of moving (C), (C) ..., Japanese Utility Model Laid-Open No. 5-45738 and Japanese Patent Application Laid-Open No. 2-108777 are known. However, the device described in each of these publications has a complicated structure and is high in cost, and cannot be used easily.

[0007]

As described above, the conventional curved traveling type moving partition has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a rail branching device capable of selecting a rail to enter, and a curve traveling type moving partition provided with a plurality of partition rails.

[0008]

In the rail branching device of the present invention, a swing cam is attached to the branching portion of the rail. The swing cam has a structure capable of swinging by a predetermined driving means, and operates so that the swing cam moves in and out of a branched rail space. The swing cam hits a guide roller attached to the suspension vehicle to control the traveling direction of the suspension vehicle. The swing cam has a guide surface that curves along the guide groove, and is advanced to guide the guide roller when the suspension vehicle is traveling in a curve, and is retracted when the suspension vehicle is to travel straight.

Here, the driving means for the swing cam is not particularly limited, and for example, a rotary cam, a magnet, a gear mechanism or the like can be adopted. Also, it is possible to swing by manually operating the handle. And, the rail branch device is provided with a sensor such as a photoelectric tube,
I am able to confirm the existence of a suspension car. That is, the swing cam functions so as not to operate when the suspension vehicle exists in the branch rail. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

1 (a), 1 (b), 2 (a) and 2 (b) are schematic views of a branching device for a curved traveling type moving partition of the present invention. This branching device is attached to the branching portion A in FIG. 5 and controls the suspension vehicle so as to travel to the partition rail (g) or the partition rail (h). Further, as shown in FIG. 4, the suspension vehicle which is installed in the rail and suspends the moving panel has a guide roller attached to the upper portion thereof, and the route for the suspension vehicle to enter the storage rail is regulated. However, the number and height of the guide rollers are determined by the relationship between the pull-out rail and the guide block mounted on the branch portion of the storage rail.

In FIGS. 1 and 2, 1 is a swing cam, 2 is a rotary cam, and 3 is a coil spring. The swing cam 1 is attached by cutting a part of a rail side piece 4.
A support shaft 5 is provided on one side of the swing cam 1, and the support shaft 5 is attached to a rail upper piece so that the swing cam 1 can swing about the support shaft 5. The oscillating cam 1 forms a curved guide surface 6, and the guide surface 6 is formed so as to conform to the guide groove 7a of the rail. That is, when the hoisting vehicle moves on the rail, the guide roller contacts the guide surface 6 of the swing cam 1 and is guided in the direction of the guide groove 7a. vice versa,
If it does not hit the guide surface 6, it moves in the direction of the guide groove 7b.

The rocking cam 1 shown by the solid line in FIG. 1 (a) is a case in which the guide groove 7b is closed and the guide groove 7a side is opened. 1 swings, and the guide groove 7b can be opened as shown by the swing cam 1 by the one-dot chain line. Therefore, the hoisting vehicle that has proceeded from the right direction will proceed straight ahead and proceed toward the guide groove 7b. Here, the swing cam 1 has a coil spring 3
Are connected to each other and urge a spring force to draw them toward the rotary cam 2. Therefore, the swing cam 1 does not separate from the rotary cam 2 and can swing with the rotation of the rotary cam 2.

The rotary cam 2 rotates about its shaft 8, and a motor 9 is provided on the ceiling to drive the rotary cam 2. However, the shaft 8 extends the plug 10 downward so that it can be operated even when the motor 9 does not operate due to a power failure or the like. Therefore, it is possible to fit the socket into the plug 10 through the opening of the ceiling panel 11 and rotate the rotating cam 2 with the handle.

By the way, when the moving panel is moved, which direction the swing cam 1 faces and which guide groove 7 is used.
I don't know if a and 7b are closed. Therefore, the dock 12 is extended to the rocking cam 1 and rocked together with the rocking cam 1, and the tip position of the dock 12 is detected by a sensor. In the figure, proximity switches 13a and 13 are used as sensors.
b is used, and the tip of the dock 12 is the proximity switch 13
When it is close to a, only the guide groove 7a is opened, and the suspension vehicle 14 is bent and moved. On the contrary, if the tip of the dock 12 is close to the proximity switch 13b, the guide groove 7
When b is opened, the suspension vehicle 14 goes straight. An indicator lamp is provided on the control panel to indicate which side of the guide grooves 7a, 7b is open.

The rotary cam 2 is brought into contact with the swing cam 1 to swing the swing cam 1. The swing cam 1 shown in FIG.
As shown in (b), the cam roller 15 is rotatably supported, and the rotary cam 2 is in contact with the cam roller 15.
Reference numeral 16 in the figure is a pin for fixing one end of the coil spring 3 connected to the swing cam 1. The other end of the coil spring 3 is fixed to a fixed pin 17 provided on the rail side, and the swing cam 1 is always pulled to the fixed pin 17 side.

As described above, in the branching device of the present invention, the swinging cam is attached to the branching portion and the guide groove is opened / closed so that the traveling direction of the suspension vehicle can be selected.
In the above embodiment, the rotary cam 2 is used as the swinging means of the swinging cam, but the driving means for swinging the swinging cam 1 is not limited. For example, a worm gear can be attached to the support shaft 5 and a worm can be engaged with this gear, or it can be swung using an electromagnet. If a groove cam is used as the rotating cam and the cam roller 15 attached to the swing cam 1 is loosely fitted in the groove, the swing cam 1 requires the coil spring 3 in order to be completely restrained by the rotary cam. do not do.

The swing cam 1 shown in FIG.
Since the opening a is opened, the suspension vehicle 14 can move only along the guide groove 7a. Then, if the swing cam 1 retracts and the guide groove 7b is also opened, the suspension vehicle 14 moves along the linear guide groove 7b. The branching device of the present invention is provided with a safety device for restricting the swing of the swing cam. That is, the photoelectric conversion tube 18 is provided on the branch rail in order to prevent the suspension vehicle from swinging when the suspension vehicle is present inside the branch rail. In particular, when the width of the moving panel is small, the swing cam 1 may malfunction, so it is necessary to prevent this. As described above, the branching device of the present invention has the swing cam attached to the branching portion, and the following effects can be obtained.
