Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a conveying device for a suspended moving panel.

[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. 55-59288, a pair of storage rails are disposed on the main rail, the first storage rail being arranged at approximately right angles to the main rail in plan view, and the second storage rail being arranged at right angles to the main rail in plan view. The connection is made obliquely in plan view so that the distance from the first storage rail increases as the distance from the main rail increases, and one endless conveyance chain is provided along the longitudinal direction of the main rail from the first storage rail. On the other hand, a chain sprocket with a torque limiter is provided on each hanging support that is attached to the upper end of each movable panel so that it can move from the main rail to the first storage rail, and this chain sprocket is always connected to the conveyance chain. When engaged, the movable panel can be moved back and forth between the storage rail and the main rail. Further, a structure is disclosed in which the other end of the upper end of the movable panel is guided from the main rail to the second storage rail in a free state.

[Problem that the invention attempts to solve]

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 conveyance chain and move them all at once, as in the prior art, the conveyance chain must be made large enough to withstand it, and at the same time. This transport chain driving motor also had the disadvantage of being large.

In addition, as mentioned above, only one of the pair of claws at the top of the movable panel is forcibly moved, so for example, when moving the movable panel from the main rail to the storage rail section, if the movable panel has a large weight, it will be forced to move. It becomes difficult to smoothly guide the suspension support on the front side in the direction of travel that is not connected to the second storage rail. The same thing can be said when extending the moving panel from the storage rail to the main rail.

The present invention aims to solve this problem.

[Means for solving problems]

In order to achieve the above object, the present invention connects one end of each of the pair of storage rails to one side of the main rail installed on the ceiling to form a storage section, and connects the upper end of each of the plurality of movable panels. The hanging supports are fitted into both storage rails and the main rail so as to be movable along their longitudinal directions, and the hanging supports are inserted into both storage rails at appropriate pitches along their longitudinal directions. A storage section conveying device is provided for intermittently transporting both suspension supports onto the main rail or from the main rail to both storage rails. An engagement rail such as a chain is disposed along the other side opposite to the connection opening with the storage rail, and
A contact wire is arranged at the bottom of the main rail along the other side, each of the moving panels is equipped with a drive motor, and the upper part of each moving panel is equipped with a sprocket, etc. that can mesh with the rail. protrudingly provided with an engagement drive wheel, the engagement drive wheel is rotationally driven by the drive motor, and is attached to a horizontally rotatable arm of a current collector provided on the upper end surface of each movable panel. The collector is regulated so as to be biased to protrude toward the contact wire, and the distance between the front surface of the collector and the surface of the contact wire in the movable panel that moves toward the main rail from the storage rail is controlled by the engagement drive. The distance is set to be smaller than the distance between the front end of the ring and the engagement rail.

[Effect]

With this configuration, when the movable panel is fed out from the storage section into the main rail, and vice versa, when it is fed into the storage section from the main rail, the movable panel is moved by the storage section conveyance device provided in the storage section, and the movable panel is moved from the main rail. Inside, the movable panels are switched to be self-propelled by the drive device provided on the movable panels themselves, and when each movable panel is fed out from the storage section into the main rail, the sprocket is activated because the drive motor of the movable panel has already started rotating. The engagement drive wheels such as the above engage with the engagement rails of the chain while rotating, so when the engagement drive wheels approach the engagement rails while in a stopped state, the tips of the engagement teeth of the engagement drive wheels There is no possibility that the rollers collide with the rollers of the engagement rail chain and cannot be engaged.
Both can be engaged smoothly.

Also, before the engagement drive wheel meshes with the engagement rail,
Since the drive motor has already started rotating, the engagement drive wheel can start to mesh with the engagement rail when the motor's starting torque is sufficiently large, and even if the drive motor's starting torque is small, It can be used.

Further, reference numeral 43 denotes a control device incorporated in each of the movable panels P, which has a function of controlling ON/OFF of energization from the collectors 37, 37, 37 of the drive motor M2, Turn on the main switch S that operates the control device 43 in advance.
As a result, when the movable panel P located in the storage section approaches the main rail 1, each conductive wire 26, 26, 26 in the contact wire 25 is
When the respective collectors 37, 37, 37 come into contact with each other, the engagement drive wheel 34 can approach and engage the engagement rail 22 in a pre-rotated state. Contrary to the above, the limit switch L5 is set so that the moving panel P is connected to the main rail 1.
When the storage section 2 approaches a certain end along the line, the drive motor M2 is turned off so as to sense a predetermined position and stop there.

In these cases, a torque limiter 44 is provided at the engagement drive wheel 34 that meshes with the engagement rail 22, and the engagement drive wheel 34 is configured to idle if a rotational force of a certain level or more is applied to the engagement drive wheel 34.

Next, this effect will be explained.

The movable panels P1, P2, P3... stored in the pair of storage rails 2a, 2b are held by the protrusions 10, 10 on the suspension supports 5, 5 at the upper ends of the front and rear pairs of endless chains 11, 11, respectively. When the main switch of the control device 20 is turned on in the normal direction, the drive motor M1 is rotated in the normal direction, and the storage rails 2a, 2 are held between the bodies 19, 19.
The lower sides of the endless chains 11, 11 in b are advanced in the direction of the main rail 1 (arrow A). Therefore,
Movable panels P1, P2, and P3 are stored in the storage rails 2a and 2b separated by an appropriate pitch t3.
... moves in the direction of the intersection with the main rail 1 as a whole.

The first moving panel P1 is the storage rail 2a, 2b
When moving from to main rail 1, limit switch L1
The current collectors 37, 37, 37 at the tip of the upper arm 36 of the first movable panel P1, which has been turned on in advance, contact each conductive wire of the contact wire 25. 26, 26, 26, the engagement drive wheel 34 rotates via the drive motor M2, approaches and engages the engagement rail 22 at the lower part of the main rail 1.

In this state, the movable panel P1 both hanging supports 5,5
While the protrusion 10 is removed from the clamping bodies 19, 19, the engagement rail 22 and the engagement drive wheel 34 engage with each other, so that the movable panel P1 moves directly toward the right end of the main rail 1 (arrow B).

Therefore, there is no inconvenience such as when the engagement drive wheel 34 collides with the engagement rail 22 at a substantially right angle while it is in a stopped state, such as collision without the two meshing being aligned. The movable panel P can automatically run on its own along the movable panel P.Moreover, it can start traveling with the starting torque of the drive motor M2 attached to the movable panel P increased, and the predetermined horsepower of the drive motor M2 can be increased. It can be applied even to small objects.

When the tip of the movable panel P1 comes into contact with the limit switch L2 at the point where the movable panel P1 moves beyond its horizontal length and completely escapes from the intersection, the drive motor M1 is rotated in the forward direction and the second limit switch L2 is activated. The moving panel P2 is sent in the direction of the main rail 1. When this moving panel P2 is sensed by the limit switch L1 in the same manner as above, the drive motor M1 is stopped, and then the same operation cycle as above is repeated, and the moving panels P1, P2, P3...
... can be sequentially fed out toward the main rail 1.

In addition, as the tip of the arm 36 in the current collector 35 approaches the contact wire 25, the contact wire 25 is adjusted so that each current collector 37 at the tip of the current collector 36 is smoothly guided into the upper and lower separators 28 in the contact wire 25. A synthetic resin guide 45 for gradually pushing up the current collector 37 is fixed to the lower end of the bracket 30.

On the contrary, the movable panels located on the main rail 1 are moved to the storage rails 2a,
To feed into the section 2b, turn on the main switch in the control device 20 in the reverse direction. As a result, when the front end of the movable panel P in the direction of movement (arrow C) approaches the end of the main rail 1, the limit switch L3 at that location is activated, and the limit switch L5 on the movable panel P is also activated to activate the drive motor M2. Stop and stop the moving panel P.

At this time, until the limit switch L3 is activated, the endless chain 1 of the storage section conveying device 9
Since the front and rear gaps between the clamping bodies 19 and 19 in the clamping bodies 1 and 11 are located at a position that does not impede the advancement of the projections 10 of the hanging support 5, each of the projections 10 fits into the front and rear clearances of the clamping bodies 19 and 19. become. Both suspension supports 5, 5 of the movable panel P are connected to both storage rails 2.
a, 2b, this is sensed and the limit switch L3 is operated to reversely rotate the drive motor M1 of the storage section conveying device 9, and the clamping body 19 on the lower side of both endless chains 11, 11 is rotated in the opposite direction. ,1
At 9, both hanging supports 5, 5 are guided to storage rails 2a, 2b in the direction of arrow D, which is perpendicular to the direction of movement up until now. Then, when moving appropriately in the direction of arrow D, the limit switch L4 is touched and actuated to stop the drive motor M1, so that the endless chain 1
Clamping bodies 19, 19, 19, 19 in 1, 11
will be waiting at a predetermined location.

Subsequent moving panels can then be sequentially advanced towards the intersection and the same cycle described above can be repeated.

[Effect of idea]

In this way, according to the present invention, the main rail has
Along the longitudinal direction, an engagement rail such as a chain is arranged on the other side opposite to the connection opening with the storage rail, and a contact wire is arranged at the bottom of the main rail along the other side, Each movable panel is equipped with a drive motor, and an engagement drive wheel such as a sprocket that can mesh and engage with the engagement rail is provided protruding from the upper end surface of each movable panel. A current collector is provided on the upper end surface of each movable panel and includes an arm that is rotatably driven by the drive motor and is horizontally rotatable so as to press and bias the current collector toward the contact wire. As a result, the movable panels were configured to be able to move on their own.
Even if the movable panel itself is heavy or has a long vertical length, it can be easily moved.

In addition, since a conveyance device that intermittently moves the movable panel only in the storage section of the movable panel,
The movable panels can be drawn in and out from the storage rail to the main rail, or vice versa, in parallel to each other in a short time.

Further, on the upper end surface of each movable panel, a current collector attached to a horizontally rotatable arm of the current collector is regulated so as to protrude toward the contact wire, and is directed from the storage rail to the main rail. The distance between the front surface of the current collector and the surface of the contact wire in the movable panel that moves closer was set to be smaller than the distance between the front end of the engagement drive wheel and the engagement rail, so that the movable panel When moving toward the main rail from the storage rail, power supply can be started from the contact wire before the engagement drive wheel on the moving panel engages with the engagement rail, and the engagement drive wheel is engaged. Since the drive motor has already started rotating before it engages with the matching rail,
When the electric motor starting torque becomes sufficiently large, the engagement drive wheel can begin to mesh with the engagement rail.

Therefore, according to the present invention, the meshing engagement between the engagement drive wheel and the engagement rail becomes smooth, and there is no possibility that the movable panel cannot run due to poor engagement or damage due to collision between the two members, and the drive motor and It has the effect of being downsized.
