It is provided so as to detect the engagement at a position outside the lateral width of the panel so as not to exist. The detection of engagement with the wall surface is necessary for the first panel in the series of panels.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

1 to 4 of the drawings are views for explaining an example of an electric sliding wall which is an embodiment of the present invention.
In the figure, A to F are ceiling rails, and each block A
~ F are independent of each other. Here, block A is a linear part of a single ceiling rail for arranging panels suspended by a pair of front and rear runners in a row to form a wall,
C and F are two parallel storage sections for storing a large number of panels side by side in a vertical orientation in this figure. Block F is a front runner ceiling rail and C is a rear runner ceiling rail.
The block D is a guide portion that guides one side of a pair of runners of the panel suspended on the A side to the block F, the block.
B and E are turning parts that turn the running direction of the runner,
A turntable (not shown) attached to the ceiling rail allows plane rotation between the broken line state and the solid line state in the figure.

FIG. 3 shows the connection relationship between the panel and its hanging state and the electrical wiring for signal transmission / reception provided between the external operation control panel 30 and the microcomputer provided on the panel 20 (hereinafter referred to as the local CPU 21). It is a figure for explaining.
In this figure, a panel 20 is suspended by a ceiling rail 1 by a pair of front and rear first runners 5a and 5b, each of which is rotatable around a vertical axis, and is mounted on a drive shaft of a wheel 2 which is a traveling means of these runners. On the connected drive shaft 3,
Driving motors M ₁ and M ₂ are connected via a panel drive gear 22 and an electromagnetic clutch 23, respectively. A third vertical seal drive motor M ₃ for vertically driving a vertically movable sound-insulating sealing material 24 provided at the lower part of the panel is also assembled to this panel. Reference numeral 7 is a hanging bolt that suspends the panel by a runner.

Next, electrical wiring for transmitting and receiving signals will be described. The signal power line 31 from the external operation control panel 30 (hereinafter simply referred to as control panel) shown in FIG. 3 is connected to the power supply line laid on the ceiling rail in the area of block A shown in FIG. To do. The laid power supply lines of the other blocks B to F are also electrically connected to the control panel 30 independently of each other.

The signal power line 31 is connected so that signals can be transmitted from the current collectors 10a and 10b of the first runner 5a and the second runner 5b to the local CPU 21. Therefore, when the runner of the panel 20 is suspended in the block A, the electrical connection with the control panel 30 can be maintained through the power supply line 4 laid in the block A, and similarly suspended in the blocks B to F. During this time, the electrical connection between the local CPU 21 of the panel and the control panel 30 is maintained through the power feed line 4 laid in each of the blocks C to F. When one runner is suspended on the ceiling rail of block A and the other runner is suspended on the ceiling rail of block B, this panel is connected to the control panel 30 by two kinds of power lines. Will be.

Note that the local CPU 21 of the panel controls each motor M ₁ , so as to perform a predetermined traveling operation corresponding to a command from the control panel 30.
It is connected to the drive units of M ₂ and M ₃ .

A second limit switch 25 is attached to each of the front and rear ends of the panel 20, and when the panel hits a wall, an adjacent panel, or is in the vicinity of a person, the vehicle travels. So that it can be stopped
It is connected to the local CPU21. The detailed structure of the second limit switch 25 is shown in FIG.
The fitting rubber 26 assembled to the tip of the second limit switch 25 is provided at the tip of the switch so as to project, and the fitting rubber 26 is fitted into the facing recess 27 formed at the rear end of the preceding panel to switch the switch. It is designed to operate.

Returning to FIG. 3, a first limit switch 40 is provided on both side surfaces of the runner 20 in the left-right direction of FIG. 3 (that is, the traveling direction of the panel in the block A of the ceiling rail). And the function is explained in FIG.

That is, as is already understood from the explanation of FIG. 2, in the configuration of this example, the panel suspended from the ceiling blocks C and F forming the storage portion is 90 degrees horizontal when the runner travels in the block A direction. It has been rotated and therefore
The first limit switch 40 shown in FIG. 3 is located on the side surface of the storage section facing the lateral width direction of the panel.

Therefore, it is turned in the turning section (blocks B and E) and blocks C and F
When viewed from the direction of the arrow A in Fig. 2 of the panel 20 that has been hung up by the vehicle, this panel runs in the D ₁ -D ₂ direction in Fig. 1, so the panel mounted on the side of the runner When the limit switch 40 of No. 1 is engaged by the proximity of adjacent panels (actually runners), the engagement is detected, and this is transmitted as a signal to the local CPU 21 mounted on the panel, and the first and second The drive of the motor is stopped, the rotation of the wheels of the runner is stopped, and the running of the runner is stopped there. In this example, as can be seen from FIG. 1, by setting the width dimension p of the runner larger than the width dimension d of the panel 20, the runners can be stopped without the panels colliding with each other. As a result, it is possible to prevent damage to the panel surface and generation of collision noise.

FIG. 5 briefly explains the traveling control of the panel provided with such a switch, and the traveling of the runner is stopped by the detection of the engagement of the switch after the traveling is started. . The switch in the flowchart of FIG. 5 is the second limit switch 25 when the panel is carried out from the storage section to form the partition, and the switch in the flowchart of FIG. 5 is stored when the panel is stored in the storage section. Is the first limit switch
40.

(Effect of the Invention) According to the present invention, each panel of the electric sliding wall can be reliably stopped at a predetermined position in the storage portion, so that the whole can be controlled without any trouble when the drive control is automated and unmanned. effective.

In addition, in the storage section composed of parallel two-row ceiling rails, the first switch means provided on the runner prevents the panel from colliding in the width direction. Since the first switch is provided, even if each runner slips, it is possible to reliably drive the vehicle to a predetermined position. Further, in the single-ceiling rail of the block A, the second switch means can prevent the front and rear panels from colliding with each other, and there is an advantage that stable and safe operation can be performed for a long time without a failure.

Furthermore, since the second limit switches provided at the front and rear ends of the panel can stop the panel traveling even when the vehicle comes into contact with an obstacle while the panel is traveling, there is an advantage that safety of traveling work can be achieved.
