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 in a diagonal plane so that the distance from the first storage rail increases as the distance from the main rail increases, and an endless conveyance chain is provided from the first storage rail along both longitudinal directions of the main rail. On the other hand, a chain sprocket with a torque limiter is provided on each suspension 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 connected to the conveyance chain. Always engage with
The movable panel can be moved back and forth between the storage rail part and the main rail. Further, a configuration is disclosed in which another hanging support at the upper end of the movable panel is guided from the main rail to the second storage rail in a free state.

[Problems that this 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.

Furthermore, as described above, only one of the pair of suspension supports at the top of the movable panel is forcibly moved, so for example, when the movable panel is moved from the main rail to the storage rail section, the movable panel is attached to the rear suspension support. If the moving panel is pushed forward with its own body and its own weight is large, it becomes difficult to smoothly guide the hanging support on the front side in the direction of movement that is not forced to move toward the second storage rail. The same thing can be said when feeding out from the storage rail section to the main rail side.

Therefore, if the movable panel is made to be able to move on its own within the main rail using a drive device attached to the movable panel itself, but the storage section is configured to be fed out and put in using a separate storage section conveyance device, the above-mentioned problem will occur. will be resolved, but at this time of delivery,
When the engagement drive wheel attached to the moving panel engages the engagement rail attached to the main rail side, unexpected force is applied to both members due to misalignment of the engagement between the two and impact force. There was a problem.

[Means for solving problems]

Therefore, in the present invention, one end of each of the pair of storage rails is connected to one side of the main rail installed on the ceiling to form a storage section, and the suspension support at the upper end of each of the plurality of movable panels is connected to one side of the main rail installed on the ceiling. The suspension supports are fitted into both storage rails and the main rail so as to be movable along their longitudinal directions, and the suspension supports are inserted into both storage rails intermittently at appropriate pitches along their longitudinal directions. A storage section conveying device is provided for transporting both suspension supports to the main rail or from the main rail to both storage rails. An engagement rail such as a chain supported by a longitudinal support provided on the other side opposite to the connection opening with the storage rail is arranged, and a contact wire is arranged below the main rail along the other side. and on the top of each moving panel,
A horizontally rotatable current collector is provided to press and bias the contact wire toward the contact wire, and each movable panel is provided with a current collector,
A drive motor that is energized via the current collector is installed, and an engagement drive wheel such as a sprocket that can be meshed and engaged with the rail is provided protruding from the upper part of each moving panel, and the engagement drive wheel is connected to the An engagement drive wheel of a movable panel that is rotationally driven by a drive motor and moves toward the main rail from the storage rail supports the back surface of the engagement rail at a location where it engages with the engagement rail. The support body is configured to be provided with a buffer portion to which the engagement rail can retreat.

[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 panel itself is switched to be self-propelled by a drive device equipped with it, while
When each movable panel is fed out from the storage section into the main rail, the engagement drive wheel of the movable panel moving toward the main rail supports the back surface of the engagement rail at the location where it engages with the engagement rail. By providing a buffer part on the supporting body that allows the engagement rail to retreat, the force caused by collision between the two when the engagement drive wheel approaches and engages the engagement rail is alleviated, and these parts are This prevents damage and allows both to engage smoothly.

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 forward rotation direction, the drive motor M1 is rotated in the forward direction, and the storage rails 2a, 2b are held between the bodies 19, 19.
The lower sides of the endless chains 11, 11 are advanced in the direction of the main rail 1 (arrow A). Therefore, the movable panels P1, P2, P3, .
... 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 end arm 36 of the first movable panel P1, which has been turned on in advance, contact each conductive wire 26 of the contact wire 25. , 26, 26, the engagement drive wheel 34 is connected via the drive rotary motor M2.
While rotating, it approaches the engagement rail 22 at the bottom of the main rail 1 and engages with it. In this state, the moving panel P1
The protrusion 10 on both suspension supports 5, 5 is the clamping body 1
9 and 19, the engagement rail 22 and the engagement drive wheel 34 engage with each other, so the main rail 1 remains as it is.
The moving panel P1 moves toward the right end (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, and the engagement drive wheel 34 is smoothly attached to the main rail 1. The movable panel P can automatically move along the movable panel P, and the drive rotary motor M attached to the movable panel P
The motor M2 can start running with a large starting torque, and can be applied even if the predetermined horsepower of the motor M2 is small.

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 by more than its horizontal length and completely escapes from the intersection, the motor M1 is rotated forward and the second limit switch L2 is activated.
The moving panel P2 is sent in the direction of the main rail 1. When this movable panel P2 is sensed by the limit switch L1 in the same way as above, the drive motor M1 is stopped, and then the same operation cycle as above is repeated to move the movable panels P1, P2, P3... sequentially to the main rail. It can be rolled out towards 1.

In addition, as the tip of the arm 36 in the current collector 35 approaches the contact wire 25, the tip of each current collector 37 at the tip of the arm 36 is smoothly guided into the upper and lower separators 28 of the contact wire 25. Bracket 3 at line 25
A synthetic resin guide 45 for gradually pushing up the bracket 38 for the current collector 37 is fixed to the lower end.

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 point is activated, and the limit switch L5 on the movable panel P is also activated, causing the motor M
2 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, thereby moving the lower side of the endless chains 11, 11 to the clamping bodies 19, 19
At this point, both suspension 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, as the user moves appropriately in the direction of the arrow D, the limit switch L4 is touched and actuated to stop the drive motor M1, so that the endless chain 11,
The holding bodies 19, 19, 19, 19 in 11 will be waiting at predetermined locations.

Subsequent moving panels can then be sequentially advanced toward 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 three engagement drive wheels such as sprockets that can mesh and engage with the rails are provided protruding from the upper end surface of each of the movable panels, and the engagement drive wheels are connected to the In addition to being rotationally driven by a driving motor, each movable panel is provided with a horizontally rotatable current collector device on the upper end surface thereof so as to press and bias the movable panel toward the contact wire. Since the movable panel is configured to be movable, it can be easily moved even if the movable panel itself is heavy or has a long vertical length.

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 brought in and out from the storage rail to the main rail, or vice versa, in parallel to each other in a short time.

Furthermore, at a location where the engagement drive wheel of the movable panel that moves toward the main rail from the storage rail engages with the engagement rail, the engagement rail is attached to a support that supports the engagement rail from the back side. Since a buffer portion is formed that allows the engagement rail to retreat against the pressing force when the drive wheel approaches the engagement rail, it is possible to prevent the engagement drive wheel and the engagement rail from mismatching in meshing alignment. However, by retracting the engagement rail, the alignment of the two can be matched, and the impact force can be absorbed by the cushioning part, and the smooth engagement eliminates the occurrence of collision noise, improving the durability of the members, and improving the engagement. This has the effect of eliminating the inability of the movable panel to travel due to defects and damage caused by collisions between the two members.
