[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically changing the traveling direction of a moving wall by operating a switch.

[0002]

2. Description of the Related Art A moving wall is suspended from a rail provided on a ceiling and can move along the rail. A pressure contact member attached to upper and lower ends of the moving wall at predetermined positions is provided. It protrudes and is fixed. In this case, the moving wall is often required to move not only in a straight line but also in a changed direction, so that the rail is formed with a branch portion. Some of the branch portions have a rotary rotor having connection rails formed in a predetermined direction for connecting the entrance side rail and the exit side rail, like a point device of a rail on which a train travels.

[0003] Therefore, a direction changing device for a branch portion having a cross-shaped cross rail of a rotating rotor type is also known. However, in this conventional device, the suspension wheel is restrained so as to be located at the center of the branching portion, and the rotation rotor is not rotated if the vehicle is displaced from the center, and the rotation is controlled to stop if the vehicle is deviated from the center during rotation. ing. However, in reality, there is a possibility that the weight of the suspension vehicle may jump out of the rotating rotor. Therefore, in this device, there is a problem in centering of the suspension vehicle, and also a problem in restraining the suspension vehicle during rotation. Therefore, it takes time to change the direction of the suspension vehicle.

[0004] The applicant has filed an application for the registration of a utility model for an "automatic wall turning device" on April 29, 1991 as an improvement over the above-mentioned problems. This automatic direction change device is provided with a vertically movable pin on a top plate of a connection rail, which is an outer peripheral portion of a rotating rotor, and a stopper which is also vertically movable and constantly urges a spring force upward. A concave portion into which the upper end of the stopper is fitted is formed at a predetermined position, a second sensor for detecting the passage of the hanging vehicle by raising the pin is disposed, and further, the first sensor is mounted on the rail at a predetermined distance from the second sensor. It is a device provided in. However, such a configuration complicates the structure and greatly increases the manufacturing cost.

[0005]

As described above, the conventional branch device has the above-mentioned problems. The problem to be solved by the present invention is these problems, and it is possible to change the direction even if the suspension wheel is not accurately located at the center of the rotating rotor mounted on the branch portion. The present invention provides an automatic turning device for a moving wall which controls the rotating rotor to stop if it is stopped, and has a relatively simple structure and a low manufacturing cost.

[0006]

SUMMARY OF THE INVENTION The automatic turning device of the present invention has the following features to solve the above problems. That is, the above-mentioned automatic direction change device has a rotating rotor attached to a branch portion of the rail, and the ceiling rail extends in four or three directions, and sometimes in two directions around the rotating rotor. A connecting rail (a bottom plate having a guide groove) is also formed on the rotating rotor, and the hanging wheel rotates on the connecting rail of the rotating rotor, and when the traveling direction is changed by 90 °, the suspension wheel is again turned on. It moves and is guided to the ceiling rail.

Here, according to the present invention, the suspension wheel can rotate even if it is not located at the center of the rotating rotor. However, when the suspension wheel is apart from the center by more than a predetermined distance, the rotation is stopped. Is controlled. Therefore, a sensor is attached to the rotating rotor to check the position of the hanging vehicle. Also, the rotating rotor must be stopped at 90 ° rotation, a cross-shaped detection plate is provided above the center axis of the rotating rotor, and a proximity switch and a limit switch are mounted on the frame on which the rotating rotor is mounted. It is attached to the body.

[0008]

By the way, when the suspension vehicle enters the rotating rotor of the automatic turning device constructed as described above, the guide groove formed in the rotating rotor must be connected to the ceiling rail in a straight line. . Therefore, if the button on the control panel is pressed when the suspension vehicle enters the rotary rotor, the rotary rotor rotates 90 ° and stops. In this case, when the suspended vehicle is not located substantially at the center of the rotating rotor, the sensor detects the position of the suspended vehicle and the rotating rotor does not rotate. Even if the rotation starts, if the hanging wheel moves during rotation, it stops.

Along with the rotary rotor, a detection plate provided at the upper end of the center shaft also rotates, but the proximity switch detects the approach of the detection plate and stops when the rotary rotor rotates 90 °. Therefore, the direction of the hanging car is 90 °
It will be converted and the lifter will move from the rotating rotor to the ceiling rail. Of course, when it is not necessary to change the traveling direction of the suspension vehicle, the vehicle travels straight through the rotating rotor without rotating the rotating rotor. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
