Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a closed control device for a movable panel that can move by itself on a main rail provided on the ceiling side.

[Conventional technology]

Conventionally, a storage section is formed by connecting a storage rail to the end of a main rail provided on the ceiling side, and a large number of 8-hung movable panels that move along the main rail are connected to adjacent movable panels within the storage section. Various types of movable panels have been devised in which the movable panels are put in and stored in a substantially parallel manner so that their wide faces face each other, or they are sequentially let out from this stored state so that the wide faces of each movable panel are moved along the longitudinal direction of the main rail.

For example, in Japanese Patent Application Laid-Open No. 51-90736, a self-propelled towing vehicle is suspended from the main rail, and the front end of a movable panel that is let out from the storage rail is connected to the rear end of the preceding movable panel. In addition, there is a structure in which a large number of movable panels are moved at once by pulling the leading movable panel by the towing vehicle.

, [Problems to be solved by the present invention] In this case,
Since all of the movable panels move while being towed by the towing vehicle in front of them, gaps are created between the movable panels at adjacent positions before and after being towed. Therefore, in order to seal the movable panels so that there are no gaps between them at the partition position, it is necessary to press the rear end of the last movable panel to be pulled toward the partition side wall.

In particular, when partitioning areas with high ceiling heights such as gymnasiums and auditoriums, the weight of the movable panels becomes considerably heavy, so a separate device is required to press the rear of the last movable panel.

When only the last movable panel is pushed forward in this way, the reaction force due to this force acts on the movable panels adjacent in front and behind, so that the pressing force is the same for all movable panels. Therefore, unless the pressing force applied to the last moving panel by the pressing device is considerably increased, it is not possible to increase the sealing pressure for sealing the gaps between each moving panel, and the driving motor for that device also becomes large. There were drawbacks.

[Means for solving problems]

Therefore, in the present invention, the main
- a plurality of movable panels scaled so as to be movable along the longitudinal direction of the main rail; each movable panel has a built-in drive that is powered by a contact wire disposed along the longitudinal direction of the main rail; It is configured to self-propel along the main rail toward the partition wall by a motor, and among the front and back removable panels located adjacent to each other, the subsequent moving panel has a movement relative to the preceding moving panel. A sensing means is provided that causes the following moving panels to stop automatically when they approach a certain distance, and the plurality of moving panels are temporarily stopped at a position immediately before the partition, and then the drive motors of all the moving panels are re-driven, and all of the moving panels are stopped. The moving panels are controlled so that they move in a sealed manner toward the partition side walls so that there is no gap between them.

[Action and effect]

According to this configuration, among the forward and backward removable panels located adjacent to each other in the self-propelled state, the subsequent moving panel has the following:
We have installed a sensing means that can detect when the preceding moving panel approaches a certain distance, so this can be used to detect when the preceding moving panel has come to an emergency stop due to a failure, or when the preceding moving panel is attached to the front end surface of the preceding moving panel. When stopped by an emergency stop means for personnel or objects, or when stopped at a predetermined position on a partition, the subsequent moving panel can be moved close to and without colliding with the stopped preceding moving panel. Since the moving panel stops, it is possible to eliminate an inconvenient movement phenomenon of each moving panel due to a collision.

After all movable panels are stopped, each movable panel is moved toward the partition side wall by re-driving the drive motor built into each panel, so there is no need for a separate device for partitioning. become.

Considering the close contact pressure on the adjacent end faces of the front and back moving panels during partitioning work, the driving force of the preceding moving panel is generated by the driving motor of the moving panel in question, and the driving force of each of the following moving panels. Since the total sum of the driving forces from the motors acts to press the part in front of it, the sealing pressure can be increased at the sealing point of the preceding moving panel part. In other words, each movement Even if the driving force of the drive motor built into the panel is small, a large sealing pressure can be obtained as a whole.

Furthermore, in order to re-drive the previously stopped movable panels all at once in the sealing direction, it is possible to send a re-drive signal by remote control using the main rail's trolley wire, so the sealing operation is extremely simple. Can be done.

Further, each moving panel (P) is provided with an approach sensing means for stopping the self-propulsion of the following moving panel when approaching the rear of the preceding moving panel (P). For example, a sensing lever extending toward the rear of the preceding moving panel (P) is provided to protrude substantially horizontally, while the sensing lever comes into contact with the preceding moving panel (P) when the sensing lever approaches the preceding moving panel (P). A sensor is provided to detect the sensor, and the ON/OFF signal of the sensor is sent to the movable panel (P

In the embodiment shown in FIG. 1, in order to stop the movable panel that is drawn out from the storage section 2 and self-propelled in the direction of the arrow A, and on the contrary, to move it self-propelled in the direction of the arrow B so as to be retracted toward the storage section 2. It controls in two directions: to stop the panel and to stop the panel.

Therefore, for control at the time of partitioning when drawing out from the storage section 2, for each movable panel, the preceding movable panel (P)
A sensing lever 35a is provided on the rear surface side of the moving panel (P), and a sensing sensor 36a is provided on the front surface side of the following moving panel (P).

In order to sense when the leading moving panel (Pl) approaches the side wall 48 in the room, a sensing lever 3 is attached to the side wall 48.
5a is provided protrudingly. On the other hand, in order to control the storage when retracting toward the storage section 2, the sensing lever 35b is placed at the rear of the back side of the preceding moving panel (P), and the sensing lever 35b is placed at the front of the back side of the following moving panel (P). A sensing sensor 36b is provided in the section.

A control device 37 incorporated in each of the movable panels CP)

The limit switch 42 connected to the sensor 36a for partitioning is connected from the timer 41 to the reverse rotation prevention relay 40 (NG (normally closed)), and the limit switch 43 connected to the sensor 36b for storage is connected to the reverse rotation from the timer 41. Connect No (normally open) to the prevention relay 40 (see Figure 6).

Due to the proximity of the front and rear movable panels during partitioning, the limit switch 42 is activated and the drive motor (M2) is turned off.
Similarly, due to the proximity of the front and rear movable panels during storage, the limit switch 43 is actuated to turn off the drive motor (M2) and stop the drive motor (M2).

Further, a timer 41 that starts operating when the contact wire 20 is energized gives priority to the operation of the limit switch 42 after the drive motor (M2) has been temporarily stopped, and after a certain period of time, the drive motor (M2) is activated. This is to keep the motor (M2) in the ON state.

Note that a limit switch 44 with a self-holding function related to the emergency stop contact sensor 34 is connected to the leading moving panel (Pl) so as to operate in priority to both limit switches 42 and 43 ( (See Figure 7).

R1 is a relay, and THR2 is a contact.

The external control device 45 controls a movable panel (
The movable panel (PI) (P), which is located on the main rail (1) and partitions the room, is moved in the opposite direction to the above. This is an electric control device that performs control for intermittently loading the storage rails 2a and 2b in sequence, and partition sealing control, which will be described later. Therefore, a main switch (not shown) for switching the phase of the contact wire 20 is provided, and limit switches (L; 1) (R2) (R4) are activated when each movable panel (P) is moved in the feeding direction; Each movable panel (P) is connected to a limit switch (R3) that is activated when the movable panel (P) is moved in.

The limit switch (Ll) is the left and right storage rail 2a.
, 2b is extended in the direction of the main rail 1, this is sensed and associated to stop the storage section conveyance device 8.

The limit switch (R4) senses when the front end of the movable panel (P) paid out from the storage section 2 appropriately advances beyond the first storage rail 2a, and re-drives the storage section conveyance device 8. It is something.

The limit switch (R3) is installed on the main rail 1 near the second storage rail 2b, and the front end of the moving panel (P) in the main rail 1 in the direction of movement contacts the limit switch (R3) and
If N is reached, the storage section conveyance device 8 is driven for a certain period of time. Therefore, when the movable panel enters the second storage rail 2b by an appropriate distance, the storage section transport device 8 temporarily stops.

The partition sealing control is performed after the passage of the front end of the final moving panel to the main rail 1 is detected by a limit switch (not shown). That is, the sensing lever 3 which is an approach stop means provided on each of the moving panels on the main rail 1
Due to the activation of the sensing sensor 36a for 5a, all the movable panels (P) temporarily stop moving on their own. After this temporary stop, the control device 3 built in each moving panel (PI) (P)
After an appropriate period of time, the timer 41 section in 7 will automatically turn on the built-in drive motors ( M2) to O
Set it to N. As a result, all the movable panels (P) are controlled to simultaneously move toward the side wall 48 to seal adjacent movable panels.

At this time, as a means for ensuring the sealing control, as shown in FIGS. 1 and 8, the main rail 1
, a distance of a predetermined distance (12) from the side wall 48 when all the movable panels are in a sealed state, such as approximately the sum of the frontage dimensions (7!l) of the plurality of movable panels (PI) (P). A limit switch (R2) is provided at a position, for example, near the doorway 46, and the driving motor (M2) in all moving panels is installed until a sensing lever (not shown) in the last moving panel contacts the limit switch (R2).
(maintaining the power supply to the contact wire 20 by the control device 45) and the external control device in advance for the time normally required for all the movable panels to be moved and sealed again. 45 or a control device 37 for each moving panel
This may be realized by setting the timer 41 and holding a signal for turning ON the built-in drive motor (M2) for that time.

Next, this effect will be explained.

First, the movable panel (PI) stored in storage section 2 (
P) (P)... are sequentially sent into the main rail 1 by the storage section transport device 8, and after the current collector 31 in the current collector 30 provided on each moving panel comes into contact with the contact wire 20, When the main switch of the external control device 45 is turned on, the contact wire 20 of the main rail 1 is energized. This results in
Rotate the drive motor (M2) forward and move each moving panel (Pi) (P) (P) from the doorway 46 toward the side wall.
... moves in the direction of arrow A.

When the movable panel (P) comes into contact with the limit switch (L4) on the main rail 1, the contact wire 20 is turned off via the external control device 45, and the storage section conveyance device 8 is driven again. Repeat this to move the moving panels (P) out one by one.

In these cases, the partition sensor 36a is activated by the anti-reverse relay 40, but the storage sensor 36b is deactivated.

If there is an obstacle at the lower floor position of the main rail 1 in front of the leading moving panel (Pl), the contact sensor 34 at the front end of the leading moving panel (Pl) comes into contact with the obstacle, and the control device 3
7 limit switch 44 is ONL, switch S2 is O
Self-maintenance is maintained at N, which turns off switch S1.
is held at □ to stop the drive motor (M2) in the movable panel.

Even when this first moving panel (Pl) is stopped, the following moving panel (P) is moving independently, so it moves towards the rear end of the stopped first moving panel (Pi). proceed. and the subsequent moving panel (
P) advances in the direction of arrow A, the sensing lever 35a protruding backward from the rear of the leading moving panel (Pl) pushes the sensing sensor 36a of the following moving panel (P), and the drive motor (M2 ) operates to stop the vehicle. Therefore, this subsequent moving panel (P) can be stopped before colliding with the rear end surface of the leading moving panel (Pl). Even when any movable panel stops due to a failure or the like, the subsequent movable panels (P) can also be stopped one after another in the same manner as described above.

Contrary to the above, each moving panel (P) (P
) (PL) in the direction of the storage section 2 (in the direction of arrow B), the drive motors (M2) in each of the movable panels are reversed by a switch of the external control device 45. At this time, the storage sensor 36b in each movable panel is activated, and the partition sensor 36a is kept inactive, so that the self-propulsion of the following movable panel can be stopped in the same way as described above. .

When moving in the direction of the partition, the leading moving panel (Pl)
After the panel stops in close proximity to the side wall 4B, the following moving panels also temporarily stop. Thereafter, all the movable panels are moved from the control device 45 via the contact wire 20 in the direction of the side wall 48 of the partition by re-driving the internal drive motor (M2) all at once. This means that sealing work can be done easily.

At this time, even if the driving force of the drive motor built into each moving panel is small, a large sealing pressure can be obtained as a whole, and the end faces of the adjacent moving panels can be completely and firmly sealed.
