Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric partition device, and more particularly to a control device for the whole thereof.

[0002]

2. Description of the Related Art Conventionally, an electric partitioning device of this type is disclosed in Japanese Utility Model Laid-Open No. 63-169365. In this conventional device, a plurality of panels suspended by runners that run along the guide rails each have an internal controller that controls the running of each panel, and the power supply line and signal that are provided along the guide rails are provided. Electric power and signals are supplied from an external controller to each internal controller via a line to control the entire apparatus.

The power supply line and the signal line are composed of a plurality of conductive wires attached in the guide rails, and contacts of the runners of the respective panels are in sliding contact with each other.

If a plurality of such power supply lines and signal lines are provided, the cost becomes high. Therefore, an attempt is made to reduce this number as much as possible, that is, there is a plan to completely eliminate the signal lines and use only the power supply lines. There is.

Such a plan can be achieved by a signal transmission method by power line carrier on the power supply line or by pre-programming and storing the operation sequence of each panel in the internal controller of each panel.

[0006]

However, in the former signal transmission method described above, electric power and a signal are supplied by a contact provided on the runner of each panel slidingly contacting a plurality of strip-shaped conductive wires. Therefore, noise may occur at that portion, and normal signal transmission may not be possible.

Further, in the latter method of programming and storing the operation sequence, when any abnormal state occurs in any of the panels, the external controller recognizes the abnormal state or takes measures to cope with the abnormal state. There is a problem that you cannot take it.

The present invention has been made in view of the above problems, and an object thereof is to allow an external controller to recognize an abnormality in running of a panel and immediately deal with it without providing a signal line. An object of the present invention is to provide an electric partition device.

[0009]

In order to achieve the above object, the present invention provides a plurality of panels suspended by a runner which runs along a guide rail and an internal controller for controlling the running of each panel. In an electric partitioning device, which is provided respectively, so that power is supplied from an external controller to each internal controller via a power supply line provided along the guide rail, an obstacle detection means provided on each panel and an obstacle detection means The internal controller is actuated by the signal of 1) to connect the two forward / reverse switching conductive wires to each other, and the external controller is provided with each of the two forward / reverse switching conductive wires and one common conductive wire . The two conduction detecting means for respectively detecting the energization between the two and the two conduction detecting means are operated by detecting the energization. It is characterized in that it comprises a means.

In this case, the free-running runner is driven by a single-phase AC motor, and the power supply line connected to this single-phase AC motor is composed of two forward / reverse switching conductive wires and one common conductive wire. It is desirable to use three conductive wires.

Further, it is desirable that the safety means has a function of activating the alarm device by the continuity detection means.

Further, it is desirable that the internal controller has a function of stopping the traveling of the panel itself in which an abnormality has occurred by the operation of the obstacle detecting means.

[0013]

If any abnormality occurs in any of the panels during the opening / closing operation of the partition, for example, the panel hits an obstacle, a signal from an obstacle detecting means provided on the panel causes the internal controller to operate and the conducting means. Thus, the electric conduction is established between each of the forward / reverse switching conducting wires and the common conducting wire. The safety means operates by detecting the energized state by the two conduction detecting means, for example, stopping the power supply to the power supply line or activating the alarm device.

The three strip-shaped conductive plates 8a, 8b, and 8c constituting the above are attached in parallel with each other, and they are three leaf spring-like members provided on at least one runner 3 that suspends and supports each panel 2. The contacts 9a, 9b, 9c are always in contact.

Each of the contacts 9a, 9b, 9c is electrically connected to the internal controller 5, and the two contacts 9a, 9b are connected to the conduction switch 10.

The continuity switch 10 is adapted to be closed based on a signal issued from the internal controller 5 when the touch sensor 7 is activated.

Reference numeral 11 denotes an external controller mounted on the wall surface of the room, which includes a power source 12 and the conductive plates 8a, 8b, 8 described above.
The conductive lines 13a, 13b, and 13c are connected to c. The conductive lines 13 a and 13 b are for switching the motor 4 between the forward and reverse directions and are connected to the power source 12 through the forward and reverse switch 14. 13c is a common conductive line.
