Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a closed control device for a movable panel that can be self-propelled while suspended from a main rail disposed on the ceiling side.

[Conventional technology]

Conventionally, a storage rail is connected to an end of a main rail provided on the ceiling side to form a storage compartment, and a large number of suspension-type movable panels that move along the main rail are provided in the storage compartment. There have been devised various devices in which the wide surfaces of the movable panels are housed and stored substantially parallel to each other so as to face each other, or are sequentially extended from the housed state and the wide surface of each moving panel is moved along the longitudinal direction of the main rail.

As one of them, for example, in Japanese Patent Laid-Open No. 51-90736, a self-propelled towing vehicle is suspended on a main rail, and a front end of a moving panel fed out from the storage rail is connected to a rear end of a preceding moving panel. In addition, there is a configuration in which a large number of moving panels are moved at once by pulling the leading moving panel by the towing vehicle.

[Problems to be Solved by the Present Invention]

In this case, since all the moving panels are pulled and moved by the towing vehicle in front of them, a gap is created between the moving panels at the front and rear adjacent positions. Therefore,
At the partition position, the trailing edge of the last towed moving panel must be pressed against the partition side walls to provide a tight seal between all moving panels.

In particular, since the weight of the moving panel when partitioning a high-height part such as a gymnasium, an auditorium, etc. is considerably heavy, a separate pressing device for pressing after the last moving panel is required.

Thus, when pushing only the last moving panel in the forward direction, the reaction force due to this force interacts with the moving panels adjacent to the front and rear, so the pressing force on the last moving panel by the pressing device must be made considerably large. It was not possible to increase the sealing pressure for sealing the gap between the moving panels one by one. Therefore, there is a drawback that the drive motor in the pressing device also becomes large in size.

[Means for solving problems]

Therefore, in the present invention, a trolley in which a plurality of moving panels suspended along the longitudinal direction of the main rail disposed on the ceiling side so as to be movable along the longitudinal direction thereof is disposed along the longitudinal direction of the main rail. In a self-propelled mobile panel configured so as to self-propell toward the partition wall along the main rail by a drive motor built in each mobile panel that is fed from a line, , A sensing means for sensing the moving panel or the partition wall when approaching the partition wall by a certain distance is provided, and when each of the moving panels is moving along the longitudinal direction of the main rail by a signal from the sensing means. , When the leading moving panel approaches the partition wall by a certain distance, the leading moving panel is stopped by itself, and when the succeeding moving panel approaches the preceding moving panel by a certain distance, Each moving panel is provided with a control means for controlling the moving panels to stop self-propelled, and then the driving motors of all the moving panels are re-driven to face the partition side walls so that the gaps between all the moving panels are eliminated. A control means for controlling so as to move in a closed manner is provided on each of the moving panels or outside.

[Operation and effect of the invention]

According to this configuration, each moving panel is provided with a sensing means for sensing when it comes close to the preceding moving panel or the partition wall by a certain distance, and by the control means provided in each moving panel. , While each moving panel is moving along the longitudinal direction of the main rail, when the leading moving panel approaches the partition wall by a certain distance, the leading moving panel is stopped by itself, and the following moving panel is When the moving panel that comes close to the preceding moving panel is stopped by a certain distance, the moving panel that follows is stopped by itself. Or when stopped by an emergency stop means for people or objectives attached to the front end face of the preceding moving panel, or when approaching a certain distance to the partition wall. When stopped at a predetermined position, so that subsequent movement panel stops at a state of being and close without colliding against the preceding moving panel has stopped,
The inconvenient movement phenomenon of each moving panel due to a collision can be eliminated.

Then, the control means provided separately for each of the moving panels or provided externally executes a control for re-driving the drive motors incorporated in each of the temporarily stopped moving panels. Each moving panel can be individually moved toward the side wall, and a separate device for partitioning is required.

Considering the close contact pressure between the adjacent end faces of the front and rear moving panels during the partitioning work, the preceding moving panel has the driving force of the driving motor of the moving panel and the driving force of each of the plurality of moving panels following it. The sum of each driving force by the motor acts and the front (leading) of it
Since you will be pressing the moving panel and other parts of
The sealing pressure can be increased as the sealing position of the preceding moving panel portion increases. In other words, even if the driving motor built in each moving panel has a small driving force, a large sealing pressure can be obtained as a whole.

Further, in order to re-drive all the stopped moving panels in the sealing direction all at once, by re-driving by remote control using the trolley wire etc. of the main rail by the control means provided for each moving panel or outside. Since it can be done by sending a signal, the sealing operation can be extremely simple.

The limit switch 42 connected to the detection sensor 36a at the time of partition is connected from the timer 41 to the reverse rotation prevention relay 40 NC (normally closed), and the limit switch 43 connected to the detection sensor 36b at the time of storage is reversed from the timer 41. NO (normally open) is connected to the prevention relay 40 (see FIG. 6).

The limit switch 42 operates due to the proximity of the front and rear moving panels at the time of layout to turn off the drive motor (M2).
Similarly, the limit switch 43 is actuated by the proximity of the front and rear moving panels during storage, and the drive motor (M2) is turned off and stopped.

In addition, the timer 41 which starts to operate by energizing the trolley wire 20 has a structure in which the drive motor (M2) is temporarily stopped, prior to the operation of the limit switch 42, and the drive motor is driven after a certain time. The motor (M2) is kept in the ON state.

A limit switch 44 with a self-holding function, which is associated with the emergency stop contact sensor 34, is connected to the leading movement panel (P1) so as to operate in preference to both the limit switches 42 and 43 ( (See FIG. 7).
R1 is a relay and THR2 is a contact.

The external control device 45 sequentially and intermittently feeds the moving panels (P1) and (P) located in the storage section 2 toward the main rail 1 and, on the contrary, positions them on the main rail (1) to partition a room or the like. An electric control device for performing control for intermittently moving the moving panels (P1) (P) into the storage rails 2a, 2b in the reverse order to the above, and an electrical control device for performing partition sealing control described later. Is equipped with a main switch (not shown) for switching the phase of the trolley wire 20 for rotating the drive motor (M1) forward and backward, while operating when each moving panel (P) is moved in the feeding direction. The limit switches (L1) (L2) (L4) and the limit switch (L3) that operates when the moving panels (P) are retracted are respectively connected.

The limit switch (L1) is the left and right storage rails 2
When the moving panel (P) in a, 2b is drawn out in the direction of the main rail 1, it is detected so that the storage section conveying device 8 is stopped. Limit switch (L
4) is for sensing when the front end of the movable panel (P) unwound from the storage section 2 has advanced over the first storage rail 2a and re-driving the storage section transfer device 8. .

The limit switch (L3) is provided on the main rail 1 close to the second storage rail 2b, and the front end of the moving panel (P) in the traveling direction in the main rail 1 contacts the limit switch (L3).
When it becomes N, the storage section transporting device 8 is driven for a fixed time. Therefore, when the moving panel enters the second storage rail 2b by an appropriate distance, the storage section transport device 8 is temporarily stopped.

The partition sealing control is performed after detecting that the front end of the final moving panel to the main rail 1 has passed by a limit switch (not shown). That is, the sensing lever 3 which is a stop means at the time of proximity provided on each moving panel on the main rail 1.
The movement of the detection sensor 36a for 5a causes all the moving panels (P) to temporarily stop self-propelled. After this temporary stop, the control device 3 built in each moving panel (P1) (P)
After a proper time, the timer 41 portion in FIG. 7 gives priority to the limit switch 42 regardless of the operating state of the limit switch 42 (operating state by turning off the driving motor (M2)), and drives motors (M2) built in all the moving panels. ) O
Set to N. As a result, all the moving panels (P) are simultaneously moved in the direction of the side wall 48 so that the adjacent moving panels can be sealed.

At this time, as a means for ensuring the sealing control, as shown in FIGS. 1 and 8, the main rail 1
Is a position distant from the side wall 48 by a predetermined dimension (l2) when all the movable panels are in a closed state, such as a size of a total sum of front dimension (l1) of the plurality of movable panels (P1) and (P), For example, a limit switch (L2) is provided near the entrance 46, and a drive motor (M2) for all moving panels until a sensing lever (not shown) on the final moving panel contacts the limit switch (L2).
Is held in the ON state (power supply to the trolley wire 20 in the control device 45 is held), and the time normally required for re-moving and sealing all the moving panels is set in advance in the external control device. 45 or control device 37 for each moving panel
It may be realized by setting it in the timer 41 and holding the signal for turning on the built-in drive motor (M2) for that time.

Next, this operation will be described.

First, the moving panel (P1) stored in the storage unit 2
(P), (P), etc. are sequentially sent into the main rail 1 by the storage section transporting device 8, where the current collector 31 in the current collecting device 30 provided on each moving panel comes into contact with the trolley wire 20 and then externally. When the main switch of the control device 45 is turned on, the trolley wire 20 of the main rail 1 is energized. This allows
The drive motor (M2) is normally rotated to move the moving panels (P1) (P) (P) from the doorway 46 toward the side wall 48.
... moves in the direction of arrow A.

A cycle in which, when the moving panel (P) comes into contact with the limit switch (L4) on the main rail 1, the trolley wire 20 is turned off via the external control device 45 and the storage section transporting device 8 is re-driven. By repeating the above, the moving panel (P) is sequentially drawn out.

In these cases, the partitioning detection sensor 36a is activated by the action of the reverse rotation prevention relay 40, but the storage detection sensor 36a is deactivated.

If there is an obstacle in the lower floor position of the main rail 1 in front of the leading movement panel (P1), the contact sensor 34 at the front end of the leading movement panel (P1) comes into contact with the obstacle and the control device 3
7 limit switch 44 is turned on and switch S2 is turned on.
N is self-held, so that the switch S1 is held OFF, and the drive motor (M
2) Stop.

Even when the leading moving panel (P1) is stopped, the succeeding moving panel (P) is self-propelled regardless of this, and therefore, toward the rear end surface of the stopped leading moving panel (P1). proceed. Then, the succeeding moving panel (P) advances in the direction of arrow A, and the sensing lever 35a protruding rearward from the rear portion of the leading moving panel (P1) pushes the sensing sensor 36a in the succeeding moving panel (P), and the limit switch 42 is turned on. It operates so as to stop the drive motor (M2). Therefore, this subsequent movement panel (P)
Can be stopped before colliding with the rear end face of the front moving panel (P1). Even when an arbitrary moving panel is stopped due to a failure or the like, the moving panels (P) following it can be stopped one after another in the same manner as described above.

Contrary to the above, each moving panel (P) in the main rail 1
When (P) and (P1) are self-propelled in the direction of the storage section 2 (direction of arrow B), the drive motor (M2) in each of the moving panels is reversed by the switch of the external control device 45. At this time, the storage sensor 36b is activated in each moving panel, and the partition sensor 36a is kept inactive to stop the self-propelling of the succeeding moving panel as described above. .

When moving in the direction of the partition wall, the front moving panel (P
After 1) stops in the state of being close to the side wall 48, the subsequent moving panel also temporarily stops. After that, the control device 4
5 through the trolley wire 20 again all moving panels,
By re-driving the drive motors (M2) built in itself at the same time to move them toward the side wall 48 of the partition all at once, the sealing work can be simplified.

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