Next, the operation of the electric sliding door constructed as described above will be explained.

Now, FIG. 3 shows the opened state of the door in which the panels P1 to P8 are stored in the first and second storage rails 6.7 and the hinged door P9 is rotated directly below the main rail 5.

From this state, rotate the hinged door P9 to open the panels P1 to P1.
When the closing push button switch (as shown) is closed to close the door, the rotation of the gear motor 0 causes the sprocket wheel 62, chain 63, sprocket wheel 59, 57, chain 64, and sprocket wheel 48 to be moved. The bolt 46 is rotated through the bolt 46, and the hinge door P9 is thereby rotated counterclockwise in FIG. 3 about the bolt 46.

Then, when the hinge door P9 rotates until it becomes parallel to the wall surface W as shown by the dashed line in Figure 3 and is stopped, the timer of the electric control circuit (as shown) times up and the gear motor 0 is stopped. At the same time, the relay of the electric control circuit operates to start the motor 39, and the double chain 34
is rotated in the direction of the arrow in FIG. 3, and the first and second runners 13
．． 26 is moved toward the main rail 5 along both storage rails 6.7, and each panel P1 to P8 is also moved in the same direction.

When the first runner 13 of the first panel P1 operates the first limit switch LSI, the stopper 41 of the first stop device 40 is moved down, and the first runner 13 of the second panel P2 is stopped, and the second and subsequent panels are stopped. panels P2 to P8 are stopped.

When the first panel P1 is transferred to the main rail 5 and its second runner 26 operates the second limit switch LS2, the stopper 41 of the first stop device 40 is moved upward and the second and subsequent panels P2 to P8 are moved again. Ru.

Then, when the first runner 13 of the second panel P2 operates the limit switch LSI, the stopper 41 is moved down again to stop the third and subsequent panels P3 to P8, and the second runner 26 of the second panel P2 is activated. When the limit switch LS2 is activated, the stopper 41 is moved upward, and the third and subsequent panels P3 to P8 are moved again.

Thereafter, in the same manner as the above-described panel feeding operation, the remaining panels P3 to P8 are also smoothly fed out one by one from the storage rail 6.7 to the main rail 5 at regular intervals without interfering with each other.

When all the panels P1 to P8 are sent out to the main rail 6, the motor 39 stops and the chain 34 stops sending out the panels, and at the same time, the relay in the electric control circuit is activated and the gear motor 0 is reversed again. , the hinged door P9 is rotated clockwise about the bolt 46 from the position shown by the dashed line in Figure 3.

When the hinged door P9 is moved directly below the main rail 5 and stopped by a stopper (not shown) provided on the main rail 5, the timer times up and the hinged door P9 where the geared motor 0 has stopped is stopped.

At the same time, the enlargement/reduction panel P9' of the hinge door P9 is enlarged by an enlargement/reduction device (not shown), and each panel P
1 to P8 and the door P9 are pressed against each other, and a floor contact device (not shown) provided at their lower ends is also pressed against the floor surface, completing the closing of each panel.

On the other hand, when the opening push button switch (not shown) is closed in order to open the hinged door P9 and send the panels P1 to P8 to the storage rail to open the door from the closed state of the door shown in FIG. P9 scaling panel P
9' is reduced, and at the same time as this operation is completed, the gear motor 0 is rotated in the normal direction, and the hinge door P9 is rotated counterclockwise in FIG. The gear motor 0 is also stopped due to time-up of the timer.

Thereafter, the motor 39 is reversed, the panels P1 to P8 are moved toward the storage rail 6°7, and at the same time as the one-way motor 39 is started, the stopper 43 of the second stop device 42 is moved down and the panels P1 to P8 are stored in the second position. Second runner 26 of panel P7
is stopped, and therefore panels P7-P1 are stopped.

When the second runner 26 of the final panel P8 that is first transferred in the storage direction is guided to the second storage rail 7, the runner 2
6, the third limit switch LS3 is activated, thereby the stopper 43 of the second stopping device 42 is moved upward, and the second and subsequent panels P7 to P1 are again transferred in the storage direction.

When the stopper 43 of the first stop device 42 is moved up, it is automatically moved down and stopped, so the third and subsequent panels P6 to P1 are stopped, and the second panel P7 switches the nomit switch LS3. When activated, the stopper 43 is moved upward again and the third and subsequent panels P6 to P1 are transferred.

Thereafter, the above-described panel storage operation is sequentially repeated, and the panels P6 to P1 are smoothly stored one by one into the storage rail 6.7 at regular intervals without interfering with each other.

When the storage of panels P8 to P1 is completed, the motor 39 and bubble chain 34 stop, the gear motor 0 is reversed, and the hinge door P9 is rotated from the position indicated by the chain dotted line in Figure 3 directly below the main rail 5 around the bolt 46. moved and stopped,
Complete opening the door.

Now, in the embodiment of the present invention, a flange part is formed in the middle of the bolt 17 for suspending the panel, so that the weight of the panel acts on the upper surface of the runner main body 14 through the flange part 17a, and the double chain 34 A sprocket wheel 18 driven by is rotatably supported on the upper surface of the flange portion 17a via a lining 23, and a leaf spring 21 is pressed onto the upper surface of the wheel 18 via the lining 23 with a bolt 22. Therefore, even if the subsequent panel is stopped by the stoppers 41 and 43, the sliding wheel 18 will idle against the frictional resistance between the sprocket wheel 18 and the flange portion 17a, allowing the double chain 34 to continue rotating. This allows only the preceding panel to be transferred intermittently, and the bolt 22
sprocket wheel 1 by adjusting the tightening force of
The pressure contact friction resistance of No. 8 can be adjusted to the optimum state according to the weight of the panel.

That is, as the weight of the panel increases, the force for conveying the panel also increases proportionally, but the pressure friction resistance of the sprocket wheel 18 is adjusted so that the panel is only rotated idly by a force slightly greater than this force. , the power for transporting the panel by the double chain 34 and its fluctuation can be reduced, and the panel can be transported smoothly.

Note that the present invention can also be embodied in the following embodiments.

(a) Leaf spring 21. Instead of the bolt 22, a coil spring (not shown) is fitted into the upper end of the bolt 17, and the coil spring is pressed into contact with the chain holder 20 by a nut.

(b) The power transmission mechanism using the sprocket 18 of the first runner 13 and the double chain 34 is replaced by a mechanism such as a timing belt and a timing pulley.

As detailed above, the present invention is designed to prevent a runner for suspending and transporting panels from being transported along an upper banger rail by a panel transporting device, to be stopped by a stopper and to apply a certain external force, that is, to push the panel. A follower that interlocks with the belt-shaped conveyor is attached by pressure bonding so that the pressure friction resistance can be adjusted by a biasing means so that the belt-shaped conveyor is rotated idly only when a force greater than the force necessary for conveying the belt is applied. By this, even if a subsequent panel is stopped by a column or a panel stop device for intermittent transfer of panels, it is possible to continue driving the band-like conveyance body of the panel conveyance device and to convey the preceding panel. This has the effect of reducing the power required for successive driving of the belt-like conveying body and the fluctuation thereof, thereby allowing the panel to be conveyed smoothly, and furthermore, the structure and manufacturing are simple, and costs can be reduced.
