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 German Patent No. 2653328, a driving device is mounted on the moving panel itself,
This self-propels along the main rail, and when moving the moving panel from the storage section to the main rail, it is connected by a connecting rail that can rotate horizontally.
The direction is changed by rotating the movable panel together with the connected rail.

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, each movable panel has a long vertical length and is considerably heavy. Therefore, the structure described above has the disadvantage that the structure of the storage section is extremely complicated and must be made sturdy.

[Problems that this invention attempts to solve]

Therefore, on one side of the main rail installed on the ceiling,
One end of each of the pair of storage rails is connected to form a storage section, and the suspension support at the upper end of each of the plurality of movable panels is movable along the longitudinal direction within both storage rails and the main rail. The two hanging supports are intermittently conveyed along the longitudinal direction of the two storage rails at appropriate pitches, and both hanging supports are fed out onto the main rail, or both are fed out from the main rail. The above-mentioned drawbacks can be solved by providing a storage section conveyance device for feeding the storage section into the storage rail. There was a problem in that it moved laterally toward the storage rail and could not move smoothly in the direction of 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. A hanging support is inserted into both storage rails and the main rail so as to be movable along the longitudinal direction thereof, and a hanging support is inserted into the lower surface of the top plate of both storage rails so as to move intermittently along the longitudinal direction. An endless conveying body configured to A pair of front and rear clamping bodies are fixed at appropriate intervals, and the length of the pair of clamping bodies along the width direction of the storage rail is smaller than the hollow inner width dimension of the storage rail, and the pair of runner receiving surfaces on the storage rail are fixed. This is set larger than the guide groove width between the two.

[Effect]

With this configuration, when the movable panel is fed out from the storage section into the main rail, and vice versa, when the movable panel is fed into the storage section from the main rail, a pair of front and rear panels attached to the endless transport body arranged along the storage rail of the storage section are used. The clamping body can clamp the front and rear of the protrusion of the suspension support on the movable panel and transport it.

The length of the pair of clamping bodies along the width direction of the storage rail is set to be smaller than the hollow inner width dimension of the storage rail and larger than the guide groove width between the pair of runner receiving surfaces of the storage rail. At the intersection of the storage rail and the main rail, the length of the pair of clamping bodies stopped there is used to guide the protrusion on the suspension support in the movable panel toward the main rail, and the suspension support is The suspension support is made unable to move laterally until it crosses the intersection, allowing the suspension support to run smoothly along the main rail without being displaced laterally in the direction of the storage rail.

[Example] Next, the present invention will be explained based on an example. In the figure, 1 indicates a main rail installed on the ceiling via a suspension frame (not shown), and one end of the main rail 1 has a The storage section 2 is formed by joining a pair of storage rails 2a and 2b arranged in parallel at appropriate intervals in a substantially perpendicular direction in a plan view.

Fold the lower ends of b, 3a', and 3b' inward,
The upper surfaces thereof are configured to form runner receiving surfaces 4a, 4b, 4a', 4b' which are inclined downward toward the center. As shown in FIG. 10, the hollow inner width dimension of the main rail 1 and storage rails 2a, 2b is H1, and the guide groove width between the pair of runner receiving surfaces 4a, 4b, 4a', 4b' on the main rail and storage rails is H1. Let the dimension be H2.

When the storage rails 2a and 2b are moved from the main rail 1 to the storage rails 2a and 2b, the rotating rollers 8a and 8b are in contact with one runner receiving surface 4b', and the rotating rollers 8c and 8d are in contact with the other runner receiving surface 4a'. 2a, 2b
It is configured to run inside in its longitudinal direction. Further, on each upper surface of the roller receiving plates 7, 7, a protrusion 10 is provided which engages and disengages a storage section conveying device 9 provided along each storage rail 2a, 2b, which will be described later. At this time,
In a plan view of the hanging support 5, a protrusion 10 is provided at approximately the center thereof. Further, a rotor 10a may be provided at the upper end of this protrusion 10.

The storage section conveying device 9 provided along the longitudinal direction of the pair of storage rails 2a and 2b is connected to both storage rails 2.
Endless chain 1 arranged along the upper surfaces of a and 2b
1, 11, sprocket wheels 12, 12, 13, 13 that wrap around and support these, and a drive motor M1 that can rotate in forward and reverse directions, and both storage rails 2
One vertical plate 3 of the main rail 1 on the opposite side to the connection opening at the intersection of a, 2b and the main rail 1
Sprocket wheels 13, 13 are fixed to the drive shaft 15, which is rotatably supported by a bracket, on the outside of the openings 14, 14 drilled in a.
Sprocket wheels 12, 12 are fixed to the free ends of the storage rails 2a, 2b on the long shafts 16, which are also rotatable, and an endless chain 1 is wound between the sprocket wheels 12, 13.
1 is a top plate 18 whose lower side is storage rails 2a and 2b.
The drive shaft 15 is arranged on the bottom surface of the drive shaft 15 so that its upper side is located on the top surface of the top plate 18, and the drive shaft 15 is configured to be rotated forward and backward by a drive motor M1 via a chain.

A pair of front and rear clamping bodies 19, 19 are placed on the outer circumferential surfaces of the endless chains 11, 11, so that the thickness t1 of the movable panel P and the adjacent movable panels P, They are attached at an appropriate pitch t3 corresponding to the sum of the predetermined gap t2 between the two. These clamping bodies 19, 19 are configured to move each hanging support 5 back and forth along storage rails 2a, 2b while sandwiching the front and back of the protrusion 10 on the upper surface of each hanging support 5 from above.

The pair of holding bodies 19, 19 is the eighth
As shown in Figures to Figure 10, it can be stopped at each intersection between the main rail 1 and the storage rails 2a, 2b.
In the stopped state, the protrusion 10 on the upper surface of the suspension support 5 is guided along both the clamping bodies 19, 19, and the suspension support 5 can move along the main rail 1.

At this time, the left and right length l2 of the pair of clamping bodies 19, 19 is smaller than the hollow width dimension H1 of the storage rails 2a, 2b, and the width of the guide groove between the pair of runner receiving surfaces 4a', 4b' in the storage rails. Dimension H

As a result, when the pair of rotating rollers 8b and 8c move from the inclined runner receiving surface 4b of the main rail 1 to the inclined runner receiving surfaces 4a' and 4b' of the storage rail at the intersection, the rotating rollers and the inclined runner receiving surface come into contact with each other. It is configured to make it impossible for the hanging support 5 to tilt or move toward the storage rail due to the point 45 changing to the lower side, and to allow the hanging support 5 to move substantially linearly along the main rail 1 without meandering. It is something to do.

It goes without saying that the present invention can also be applied to a case where the runner receiving surface is substantially horizontal.

In addition, the main rail 1 and storage rails 2a, 2b
On the lower surface of the top plate at each intersection with
A pair of left and right guide bodies 46, 46 are fixed to each other to prevent the postures of the parts 9, 19 from tilting to the left or right.

Reference numeral 20 indicates movable panels P1, P2, P3... located on the storage rails 2a, 2b, on the main rail 1.
The movable panels P1, P2, P3, etc., which are located on the main rail 1 and partition the room etc., are intermittently drawn out in sequence toward the storage rails 2a, 2b in the reverse order. The control device 20 is equipped with a main switch (not shown) for rotating the drive motor M1 in forward and reverse directions, and also moves each movable panel P in the feeding direction. limit switches L1 and L2 that operate when each movable panel P is moved; and limit switches L3 and L3 that operate when each moving panel P is moved in;
Each is connected to L4. The limit switch L1 is provided in one vertical plate 3 of the main rail 1, and the limit switch L1 is installed in the left and right storage rails 3.
When the movable panels P in a and 2b are paid out in the direction of the main rail 1, this is sensed and related to stop the storage section conveyance device 9. 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 9. The limit switch L3 is provided on the main rail 1 near the second storage rail 2b, and the limit switch L4 is provided on the main rail 1 near the second storage rail 2b.
a, 2b, both of which are used when the movable panel P approaches the terminal end of the main rail 1 provided with the storage section and from the main rail 1 to the storage rail 2.
This is related to the ON/OFF operation of the storage section conveyance device 9 when loading into the storage section a, 2b, and as the movable panel P advances within the main rail 1, the front end of the movable panel P in the direction of travel moves into the limit switch L3.
When the limit switch L4 comes into contact with and turns on, the storage section conveyance device 9 is driven, and when the limit switch L4 turns on, the storage section conveyance device 9 is stopped.

The storage rails 2a and 2b in the main rail 1
A support 2 is provided along the longitudinal direction of the main rail 1 on the lower surface of the runner receiving surface 4a on the opposite side to the joining opening with the main rail 1.
1 is fixed and inserted into the opening of the support body 21 with the back surface of the engagement rail 22 such as a chain supported, and the engagement rail 22 is fixed with screws 23 at appropriate intervals. The support body 21 at the location where the engagement drive wheel 34 (to be described later) approaches and engages the front surface of the engagement rail 22 from the storage portion 2 is provided with rubber or the like that allows the engagement rail 22 to retreat in response to the tilting impact force. A buffer section 24 is formed to accommodate a buffer material.

Further, reference numeral 25 denotes a plurality of conductive wires 26, 2 disposed substantially parallel to the lower part of the engagement rail 22.
6, 26, each conductive wire 26 has skirt portions 27, 27 having flexibility in the upper and lower sides, respectively.
The separators 28 are sandwiched between longitudinal separators 28 that are made of electrical insulating material and have a horizontal U-shaped cross section, and then inserted into the grooves of longitudinal wiring holders 29 that are also made of electrical insulating material. It is fixed to a bracket 30 which is arranged parallel to each other in multiple upper and lower stages and protrudes downward from the side surface 3a of the main rail 1.

Reference numeral 31 denotes a drive device attached to each of the movable panels P, and the drive device 31 includes a forward/reverse rotation drive motor M with a deceleration mechanism housed within the thickness of the movable panel P.
2, an engagement drive wheel 34 such as a sprocket fixed to a drive shaft 33 that is driven by the drive motor M2 via a transmission mechanism 32 and protrudes upward from the upper end of the movable panel P; It consists of a current collector 35 which is provided horizontally rotatably and which collects current from the aforementioned contact wire 25 and supplies the power to the drive rotary motor M2. A bracket 38 incorporating multiple stages of current collectors 37, 37, 37 capable of contacting the respective conductive wires 26, 26, 26 of the contact wire 25 is pivotally supported via a shaft 39 so as to be vertically movable and horizontally rotatable. The base of the arm 36 is pivoted horizontally to a support 40 protruding from the upper end surface of the moving panel P, and a bracket 41 fixed to the support 40 and the base of the arm 36 are connected by a spring 42 to each of the current collectors 3.
The tip surfaces of the contacts 7, 37, and 37 are pressed so as to come into contact with the conductive wires 26, 26, and 26 of the contact wire 25.

Further, 43 is a control device incorporated in each of the movable panels P, which has a function of controlling ON/OFF of the power supply from the collectors 37, 37, 37 to the driving rotary 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 driving rotary 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 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.

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
At this time, until the limit switch L3 is activated, the endless chain 1 of the storage section conveying device 9 is stopped.
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. In this way, when the suspension support 5 crosses the intersection with the storage rail along the main rail 1, even if the rotating roller tries to move laterally toward the storage rail at the intersection, the pair of clamping bodies 19, 19 Since the protrusion 10 is guided so as not to be able to move laterally, the hanging support 5 will not accidentally fit into the storage rail side.

When both suspension supports 5, 5 of the movable panel P come to a position facing both storage rails 2a, 2b,
By sensing this and operating the limit switch L3, the drive motor M1 of the storage section conveying device 9 is reversely rotated, and the two hanging supports 5, 5 are held by the clamping bodies 19, 19 on the lower sides of the endless chains 11, 11. Storage rail 2 in the direction of arrow D, which is perpendicular to the current direction of travel.
Leads to a, 2b. Then, when moving appropriately in the direction of arrow D, the limit switch L4 is touched and actuated, and the drive motor M1 is stopped.
19, 19 will be waiting at a predetermined location.

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

[Effect of idea]

As described above, according to the present invention, the endless conveyor that intermittently moves the movable panel only to the storage section of the movable panel has a protrusion that protrudes upward from both suspension supports of each movable panel. Since a pair of front and rear clamping bodies that clamp the front and rear sides of the direction are fixed at appropriate intervals, the movable panel can be moved from the storage rail to the main rail, or vice versa, from the main rail to the storage rail in a state parallel to each other and in a short time. , it can be made to be able to be rolled out.

Then, the length along the width direction of the storage rail of a pair of clamping bodies for clamping the protrusion protruding upward at substantially the center in a plan view on both suspension supports of each movable panel is determined. Since it is set to be smaller than the hollow inner width dimension and larger than the guide groove width between the pair of runner receiving surfaces on the storage rail, it is difficult to move along the main rail at the intersection between the storage rail and the main rail. Even if the suspension support tries to tilt or move sideways due to the discontinuity or inclination of the runner receiving surface on the lower surface,
This has the effect of preventing this, allowing the suspension support to move substantially linearly along the main rail, and eliminating failures at intersections.
