DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric partitioning device and, more particularly, to a device for controlling the direction of a rotating rail.

[0002]

2. Description of the Related Art Conventionally, in an electric partition device in which the traveling direction of each partition panel can be changed by turning the pivot rail while the traveling device is located in the pivot rail, Generally, the direction of the rotating rail is controlled by setting the rotating range of the moving rail to about 90 °.

[0003] In such a control of the direction of the rotating rail, a fixed type rotation stopper for restricting the turning angle of the rotating rail can be installed, so that stop control at the end of the turning of the rotating rail is easy. In addition, there is an advantage that the trolley does not reversely enter a trolley wire, which is a power supply system generally used in the electric partitioning device.

[0004]

However, in such control, the turning direction of the rotating rail is set in advance to either the left or right, so that the partition panel is moved in the opposite direction to the turning direction of the rotating rail. It is necessary to take a switchback method in which the partition panel is once moved in the same direction as the turning direction of the rotating rail, and then the partition panel is moved backward, in order to change the direction of the partition panel. However, there is a problem that the control program becomes complicated and it takes time to change the direction of the partition panel.

[0005] In order to solve such problems, the present invention simplifies a control program for changing the direction of the partition panel, and efficiently changes the direction of the partition panel. It is an object of the present invention to provide a rotation rail orientation control device.

[0006]

In order to achieve the above-mentioned object, an apparatus for controlling the direction of a turning rail of an electric partitioning device according to the present invention is provided at an intersection of the partitioning rail fixed to a ceiling. A traveling device in which a rotating rail selectively aligned with any one of the rails is provided on the ceiling so as to be pivotable by a vertical drive shaft interlocked with a motor, and is provided on a plurality of partition panels so as to be rotatable around the vertical axis, While being mounted so as to be able to self-run along, each partition panel is movably suspended below each rail, and the turning rail is turned while the traveling device is positioned within the turning rail. Thereby, in the electric partition device that can change the traveling direction of each partition panel, in a state where the traveling device that has traveled on the partition rail has entered the rotary rail and stopped. The rotating rail can be turned in either direction to the left or right with respect to the traveling direction of the traveling device, and the traveling device always rotates while maintaining the same traveling direction as when entering the rotating rail. The turning direction of the turning rail is controlled so that the rail can travel from the rail to the partitioning rail. According to this feature, the turning rail is controlled so as to be able to turn in either the left or right direction with respect to the traveling direction of the traveling device, so that the partition panel can be turned in any direction, and Even after the change, the traveling device can be made to travel without retreating while maintaining the same traveling direction as before, so that the control program for changing the direction of the partition panel can be simplified and the direction change can be shortened. It can be performed efficiently in a short time.
