Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a movable panel that can move on its own while suspended from a main rail provided on the ceiling side.

[Conventional technology]

Conventionally, a storage rail is connected to the end of a main rail installed on the ceiling to form a storage section, and a large number of suspended movable panels that move along the main rail are connected to each other within the storage section. Various 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 moving panel that is let out from the storage rail is connected to the rear end of the preceding moving panel. There is also a structure in which a large number of movable panels are moved at once by towing the leading movable panel by the towing vehicle.

However, in cases where the height from the ceiling to the floor of the room is considerably high, such as in a gymnasium or school auditorium, the weight of each movable panel becomes considerably heavy. Therefore, in order to engage all the movable panels with one tow vehicle and move them all at once as in the prior art, the drive motor of the tow vehicle also has to be large. It was hot.

[Problems to be solved by the present invention]

Therefore, a current collector installed in each movable panel is used from a contact wire placed along the main rail to drive a built-in drive motor for each movable panel, so that the motor can move the panel along the main rail. If each movable panel is made to move independently, the drive motor can be downsized and the above problem can be solved.

However, if the leading self-propelled panel or any one of these self-propelled panels breaks down and stops, or the front end of the leading movable panel in the direction of travel comes into contact with an appropriately determined position, for example, the end position of an indoor partition. When the moving panel reaches the partition position and stops, the moving panel that follows collides with the rear end of the stopped moving panel. As a result, the movable panel that is stopped will move due to the impact force of the collision, and the following movable panels will also collide one after another, creating the risk of damaging parts such as the drive transmission part of each movable panel. .

[Means for solving problems]

Therefore, in the present invention, a movable panel suspended in a main rail disposed on the ceiling so as to be movable along its longitudinal direction is connected to a contact wire disposed along the longitudinal direction of the main rail. The movable panel is configured to self-propel along the main rail by a built-in drive motor supplied with electricity, and in the self-propelled state, one movable panel of both front and rear movable panels located adjacent to each other is provided with a protruding sensing lever extending toward the other moving panel, and can come into contact with the sensing lever when the other moving panel approaches the one moving panel by a certain distance. A sensing sensor is provided, and the sensing sensor is configured to stop the self-propulsion of the other moving panel.

[Action and effect]

According to this configuration, each of the plurality of movable panels that self-propels along the main rail is provided with a protruding sensing lever that extends toward the mating movable panel both forward and backward, such as near its front end and near its rear end. On the other hand, each moving panel is equipped with a sensor that detects when the sensing lever approaches, so when any preceding moving panel among the moving panels moving in the same direction stops, the adjacent moving panel When the following moving panel approaches the stopped moving panel,
The sensor on the moving panel that approaches the sensing lever provided on the stopped moving panel comes into contact with it, and the activation of this sensor stops the drive motor of the following moving panel that is moving and stops self-propulsion. be.

Therefore, the subsequent moving panel can be stopped before it collides with the stopped moving panel.

As a result, when the preceding moving panel comes to an emergency stop due to a malfunction, when it stops due to an emergency stop means for personnel or objects attached to the front end surface of the preceding moving panel, or when it stops at a predetermined position, Since the subsequent moving panels stop in a state close to the stopped moving panel without colliding with it, it is possible to eliminate an inconvenient movement phenomenon of each moving panel due to collision.

This is to stop the movement of the moving panel P. This safety device is optional.

Further, each moving panel P is provided with means for sensing proximity to the preceding moving panel.

A sensor is installed, and the ON/OFF signal of the sensor is transmitted to the movable panel P.
When a following moving panel approaches a preceding moving panel, the self-propelling of the following moving panel P is stopped in conjunction with a control device 37 built in, which will be described later.

In the embodiments shown in FIGS. 1, 8 and 9,
Two directions: to stop the movable panel that is drawn out from the storage section 2 and self-propelled in the direction of arrow A, and to stop the movable panel that is self-propelled in the direction of arrow B as it is retracted into the storage section 2. It is to be controlled with respect to

Therefore, in order to control the partition when drawing out from the storage section 2, for each movable panel, a sensing lever 35a is installed at the rear of the front side of the preceding movable panel P.
A sensing sensor 36a is provided at the front part of the surface side of the following moving panel P. In order to sense when the leading moving panel P1 approaches the side wall 48 in the room,

A sensing lever 35b is provided at the rear part of the back side of the moving panel P, and a sensing sensor 36b is provided at the front part of the back side of the following moving panel P.

The control device 37 incorporated in each of the movable panels P has a function of controlling the power supply from the collectors 31, 31, 31 to ON/OFF of the drive motor M2, and has an electromagnetic contact connected to the drive motor M2. Vessel 3
The relay 39 of No. 8 is associated with the reverse rotation prevention relay 40.

A limit switch 42 connected to the sensor 36a for partitioning is connected NC (normally closed) from the timer 41 to the relay 40 for preventing reverse rotation, and a limit switch 43 connected to the sensor 36b for storing the storage is connected from the timer 41 to the relay 40 for preventing reverse rotation. Connect NO (normally open) to relay 40 (see Figure 6).

When the front and rear movable panels come close to each other during partitioning, the limit switch 42 is activated to turn off and stop the drive motor M2, and similarly when the front and rear movable panels are stored, the limit switch 43 is activated and the drive motor M2 is turned off and stopped. The motor M2 was turned off and stopped.

Further, the timer 41, which starts operating when the contact wire 20 is energized, gives priority to the operation of the limit switch 42 when the drive motor M2 is temporarily stopped, and after a certain period of time stops the drive motor M2. It is kept in the ON state.

A limit switch 44 with a self-holding function, which is related to the emergency stop contact sensor 34, is connected to the leading moving panel P1 so as to operate in priority to 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 advances the movable panel P located in the storage section 2 toward the main rail 1, and conversely moves the movable panel P located on the main rail 1 that partitions the room etc. is an electrical control device for intermittently feeding the storage rails 2a and 2b in the reverse order, and the control device 45 includes a main switch (not shown) for rotating the drive motor M1 in forward and reverse directions.

Connect to 3 and 3 respectively.

The limit switch L1 senses when the movable panel P in the left and right storage rails 2a, 2b is extended in the direction of the main rail 1, and is associated with stopping the storage section conveying device 8. The limit switch L2 senses when the rear end of the movable panel P drawn out from the storage section 2 appropriately advances beyond the first storage rail 2a, and re-drives the storage section conveyance device 8.

The limit switch L3 is provided on the main rail 1 close to the first storage rail 2a, and when the front end of the moving panel P in the main rail 1 in the traveling direction contacts the limit switch L3 and turns on, the storage section transport device 8 is driven for a certain period of time. let

Next, this effect will be explained.

First, moveable panel P stored in storage section 2
1, P, P... are sequentially sent into the main rail 1 by the storage section transport device 8, where the current collector 31 in the current collector 30 provided on each moving panel is connected to the contact wire 2.
0, the switch of the external control device 45 is turned off.
When turned on, the contact wire 20 of the main rail 1 is energized. As a result, the driving motor M2 is rotated in the forward direction, and each moving panel P1, P, P... moves in the direction of arrow A from the entrance/exit 46 toward the side wall 48.

When the movable panel P contacts 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 transport device 8 is re-driven, repeating the cycle and moving sequentially. Roll out panel P.

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 P1, the contact sensor 34 at the front end of the leading moving panel P1 comes into contact with the obstacle, and the limit switch 44 of the control device 37 is turned on.
However, the switch S2 is self-held in the ON position, and thereby the switch S1 is held in the OFF position, thereby stopping the drive motor M2 in the movable panel.

Even when the leading moving panel P1 is stopped, the following moving panels P are self-propelled regardless of this, so they advance toward the rear end surface of the stopped leading moving panel P1. And the eighth
As shown in FIG. 9, the subsequent moving panel P
moves in the direction of arrow A, and the sensing lever 35a protruding backward from the rear of the leading moving panel P1 pushes the sensing sensor 36a on the trailing moving panel P,
Drive motor M2 via limit switch 42
It operates to stop. Therefore, this subsequent moving panel P can be stopped before colliding with the rear end surface of the leading moving panel P1. Subsequent moving panel P
can also be stopped one after another in the same manner as above.

This self-propelled stop operation also stops the following moving panels when the leading moving panel P1 stops close to the side wall 48 or when any other moving panel stops due to a failure etc. They are the same in that they can be

In contrast to the above, when each movable panel P, P, P1 is self-traveled within the main rail 1 in the direction of the storage section 2 (in the direction of arrow B), the drive motor of each movable panel is controlled by a switch of the external control device 45. Reverse M2. 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. .

In this way, if the following moving panel approaches within a certain distance of the preceding moving panel, the following moving panel will automatically stop self-propelling, and the following moving panel will be able to move closer to the preceding moving panel. This eliminates the possibility of a collision from behind pushing the stopped movable panel forward and colliding with people or objects in front of it. There is no inconvenience that the following moving panel itself that collides with moves backward.

In addition, in the present invention, by attaching an electromagnetic brake to the drive motor M2 or the transmission mechanism 27 in each moving panel, it is possible to quickly stop the rotation of the engagement drive wheel 29 at the same time as the drive motor M2 is stopped. By doing so, the moving distance due to the driving inertia of the moving panel can also be shortened.
