Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention hangs via a runner of a rail arranged on the ceiling of a room in a building, and moves along the rail to obtain an indoor space. The present invention relates to a partitioning panel for partitioning at a position for multipurpose use and a drive mechanism for a moving body such as a crane for transporting articles in a factory.

[Conventional technology]

Conventionally, as a drive mechanism for a partition panel, a drive motor that engages a runner rotatably with a ceiling rail, suspends and supports the partition panel on the runner, and rotates the runner in the partition panel is used. A mechanism is known in which the runner rolls along the ceiling rail based on the rotation of the drive motor to move the partition panel in a predetermined direction (Japanese Patent Laid-Open No. 60-98081).

In this mechanism, the runner is integrally formed on the upper end of the vertical shaft projecting above the partition panel and rotates about the vertical shaft, and the vertical shaft penetrates below the runner. The auxiliary runner, which is rotatably held, is installed, the ceiling rail is divided into a runner running part and an auxiliary runner running part, and the runner runs in the runner running part and is provided below the runner. The auxiliary runner is designed to run in the auxiliary runner running section.

Further, the crane normally travels in a straight line, and can be moved in a curved portion by a mechanism including a rack and a pinion.

[Problems to be Solved by the Invention]

However, in the conventional partition panel drive mechanism described above, the ceiling rail is usually formed in an R shape at the corner portion and is not formed at a right angle, so construction is difficult and the installation location of the rail is restricted. There is a problem in that the appearance becomes poor and the corners do not travel smoothly because a mechanism for traveling in the corners is not provided.

In addition, since the crane normally travels in a straight line, the moving mechanism of the corner portion has not been sufficiently studied, and the same problem as described above has occurred.

The object of the present invention is to smoothly run the corner portion, the rails in the corner portion can be arranged almost at a right angle for easy construction, and there are few restrictions on the installation location of the rail.
Another object of the present invention is to provide a drive mechanism for a moving body that maintains a good appearance.

[Means for solving the problem]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a drive runner, which is formed on the upper part of the moving body so as to support the moving body and to be rollable along a drive rail and to be rotatable, is provided. And the drive runner supports the moving body,
It is formed so as to be rotatable about a support shaft that is rotationally driven, and has a drive force transmission mechanism between the support shaft and a drive roller that rolls on a drive rail, and at a position facing the drive roller. It employs a means of having a driven roller that freely rotates without being connected to a driving force transmission mechanism.

Further, according to the second aspect, an outer roller that moves along the outer peripheral wall or an inner roller that moves along the inner peripheral wall is provided in the turning region formed by the outer peripheral wall and the inner peripheral wall in the corner portion of the drive rail. In addition, a means is adopted in which the inner peripheral wall of the drive rail has a corner that allows the inner roller to move rotationally and a corner that stops the inner roller.

[Operation] By adopting the above means, in the first aspect of the present invention, the movable body is supported by the drive runner disposed above the movable body, and the drive runner rolls on the drive rail. Since the moving body moves and the drive runner turns and changes its direction in a predetermined direction at the corner portion of the drive rail, the moving body can change its direction substantially at right angles and move. Further, when the drive runner turns, the drive roller rolls on the drive rail via the drive force transmission mechanism based on the drive force of the support shaft of the drive runner, and the driven roller rolls according to the movement of the drive roller. As a result, the drive runner can swivel smoothly and reliably in the predetermined direction at the corner.

Further, in the second invention, in the corner portion of the drive rail, the outer roller or the inner roller moves along the outer peripheral wall in the turning region formed by the outer peripheral wall and the inner peripheral wall of the drive rail, and the inner roller is When the inner roller reaches the corner of the inner peripheral wall for stopping the rotation of the inner roller, the drive runner stops rotating and moves straight from that position.

It is like this. A drive runner 18 for moving the partition panel 1 is disposed above the vertical shaft 14, and a rotary shaft 19 as a support shaft extending downward from the center of the lower part of the drive runner 18 and the vertical shaft 14 are provided. A connecting shaft 20 connected by universal joints 21a, 21b whose both ends can freely rotate is interposed between the two, and the rotational force is transmitted to the drive runner 18 via the connecting shaft 20.

The bevel gear 25, which is also provided in the inner end portion of the support shaft 26 of the drive roller 22 and 24, also constitutes a drive force transmission mechanism, so that the rotational drive force from the rotary shaft 19 is transmitted to the drive roller 22. The drive roller 22 is driven to rotate. The driving roller 22 is rotationally driven by the driving force transmission mechanism, and the driven roller 23 located at a position facing the driving roller 22 is not rotationally driven but is freely rotatable, so that the driving runner 18 can smoothly swivel. .

Outer rollers 27 are rotatably supported at the four corners of the upper surface of the drive runner 18. The drive rail 30 can be moved along the straight portion 31 and the outer peripheral wall 33 of the corner portion 32. Between the two outer rollers 27 (above the drive roller 22), two inner rollers 28 are rotatably supported at a position higher than the outer roller 27, and a linear portion 31 of the drive rail 30 or Corner section 32

Is guided in a predetermined direction by the inner peripheral wall 34 and the outer peripheral wall 35. Therefore, in this case, the outer peripheral wall 33 can be omitted.

An operating shaft 37 extending in the horizontal direction is rotatably supported in the lower part inside the partition panel 1, and one end (the left end in FIG. 1) of which is attached with a ceiling-to-ground floor contact motor 38 and the other end. A shaft hole 39 for operating a manual handle is formed in the portion. A lozenge-shaped vertical movement member 40 is supported on the operating shaft 37 so as to be movable in opposite directions with respect to the operating shaft 37 at the left and right facing portions, and the vertically facing portion is moved up and down by the rotation of the operating shaft 37. You can move.

The lower end of a ceiling-mounting lifting shaft 41 extending in the vertical direction is integrally attached to the upper end of the vertical moving member 40.
The upper end of 41 is attached to the lower end of a rubber ceiling cushion 43 extending in the lengthwise direction on the upper end surface of the partition panel 1. Further, an upper end of a floor contact lift shaft 44 extending in the vertical direction is integrally attached to a lower end portion of the vertical movement member 40, and a lower end portion of the floor contact lift shaft 44 extends along a lower end surface of the partition panel 1. It is also mounted on top of a rubber floor cushion 45.

Then, by operating the arm-contacting floor contact motor 38 or a manual handle (not shown), the upper end of the vertical movement member 40 moves upward and the lower end moves downward, the contact cushion 43 comes into contact with the ceiling, The floor-contacting cushion 45 is in contact with the floor to ensure the shielding between the rooms on both sides of the partition panel 1.

Surface of the partition panel 1 (front surface of FIG. 1)
A partition photocell 46 is attached to the upper left part of the vehicle, and a starting light projecting tube is provided at a position facing the phototube 46 so that the traveling motor 2 rotates when the light from the projecting tube strikes. . A reflection-type traveling stop photoelectric tube 47 is attached to the upper part of the left end surface of the partition panel 1, and the traveling motor 2 is stopped by the intensity of light received. A reflection type storage stop photocell 48 is attached to the upper part of the rear surface of the partition panel 1 so that the storage of the partition panel 1 is stopped by receiving light.

Further, a ceiling / contact floor contact photocell 49 is attached to an upper portion of the right end surface of the partition panel 1, so that the ceiling / contact floor contact motor 38 is operated. A storage start photoelectric tube 50 is attached below the same floor contact photoelectric tube 49 so that the storage of the partition panel 1 can be started by receiving light from a light projecting tube provided on a frame (not shown). There is. A battery charging terminal 51 is provided below the right end surface of the partition panel 1 so that the battery 3 can be sequentially charged. Further, an operation panel 52 is provided on the lower part of the front surface of the partition panel 1 so that the traveling motor 2 and the ceiling contact floor contact motor 38 can be operated.

Now, the operation and effect of the drive mechanism of the partition panel 1 configured as described above will be described.

As shown in FIG. 1, first, when the partition photocell 46 senses light from the wall side of the storage (not shown), the traveling motor 2 is driven to rotate. When the traveling motor 2 is rotationally driven,
The rotation of the rotary shaft 5 is transmitted via the differential gear 7 to rotary shafts 6a and 6b extending from the differential gear 7 in both the left and right directions.
a and 6b rotate in the same direction. These rotating shafts 6a, 6b
When it rotates, the bevel gears 17a attached to its both ends are
Since 17b meshes with the bevel gear 16 attached to the lower end of the vertical shaft 14, the vertical shaft 14 rotates and their rotation directions are the same for both vertical shafts 14. Rotation of both vertical shafts 14 is a connecting shaft
20 is transmitted to the rotary shaft 19 of the drive runner 18, and the rotation of the rotary shaft 19 is transmitted via the bevel gears 24 and 25 to the drive roller 22.
Is transmitted to Since the drive roller 22 rolls on the drive rail 30, the partition panel 1 moves in a predetermined direction.

When the first partition panel 1 reaches the corner portion 32 of the drive rail 30, the outer roller 27 of the drive runner 18 enters the turning area 60 of the drive rail 30 as shown in FIG. One of the inner rollers 28 reaches the inner peripheral wall 34 of the corner portion 32. When the drive runner 18 further moves, the entire drive runner 18 enters the turning area 60, as shown in FIG.

Then, as shown in FIG.
When the inner roller 28 rotates, the inner roller 28 moves to the inner peripheral wall 34 and the outer peripheral wall.
While moving along 35, the outer roller 27 is an outer peripheral wall.
It moves along 33 and the inner peripheral wall 34 of the straight portion 31. At this time, since the corner portion of the inner peripheral wall 34 on which the inner roller 28 moves is a rotation-permissible corner portion 61 formed in an R shape for allowing the inner roller 28 to rotate, the inner roller 28 is fixed to the inner peripheral wall. It smoothly moves along the rotation allowable corner portion 61 of 34.

Next, as shown in FIG. 8, when the drive runner 18 rotates 270 degrees, the corner portion of the inner peripheral wall 34 where the inner roller 28 is located is formed in a right angled shape for stopping the rotation of the inner roller 28. Since it is the stop corner portion 62, the rotation of the inner roller 28 is restricted by this rotation stop corner portion 62, and the drive runner 18
Does not rotate any more. Therefore, the drive runner 18 starts to move forward (left side in FIG. 8) from that position. Subsequently, as shown in FIG. 9, the drive runner 18 moves to another straight line portion 31b extending from the rotation region 60 in a direction orthogonal to the straight line portion 31a of the drive rail 30. In this way, the drive runner 18 changes its moving direction to a right angle and moves smoothly.

The connecting shaft 20 provided between the drive runner 18 and the partition panel 1 has its upper and lower ends connected by universal joints 21a and 21b, so that the partition panel 1 is pulled by the drive runner 18. As it is driven smoothly, the drive rail 30 is formed at a right angle,
Easy to install the drive rail 30 on the ceiling,
Moreover, there are few restrictions on the selection of the installation location for installing the drive rail 30. Also, the appearance when looking at the ceiling from below is good.

Next, when the partition panel 1 approaches the frame, the light from the traveling stop phototube 47 is reflected on the frame, and the traveling stop phototube 47 senses the light and stops the traveling motor 2. At this time, since the drive runner 18 travels ahead of the partition panel 1, it stops at a position preceding the stop position of the partition panel 1 and stops in a form of pulling the partition panel 1.

Next, the second partition panel 1 also moves out of the storage as in the case of the first partition panel 1 described above, approaches the first partition panel 1, and the traveling stop photoelectric tube 47 It operates and comes into contact with the first partition panel 1 and stops. At this time, the first ceiling-mounted floor-contact photocell 49 operates, the ceiling-mounted floor-contact motor 38 rotates, and the vertical movement member 40 deforms. The cushion 43 contacts the ceiling, and the floor-contact lifting shaft 44 descends so that the floor-contact cushion 45 contacts the floor. Therefore, the space between the upper edge of the partition panel 1 and the ceiling and the space between the lower edge of the partition panel 1 and the floor are completely shielded, and functions such as hermeticity and sound insulation are exhibited. Subsequently, the partition panel 1 is similarly sequentially withdrawn from the storage, and the partition is completed.

 Next, the storage of the partition panel 1 will be described.

Phototube 50 to start storing light from a light-emitting tube installed on the frame
When the contacting floor contacting motor 38 is rotationally driven, the contacting up-and-down shaft 44 moves down and the contacting cushion 43 moves away from the ceiling. Get off the floor. Then, the traveling motor 2 is rotationally driven in the opposite direction to the above, and the differential device 7, the rotary shafts 6a and 6b, and the vertical shaft 1 are driven.
4. The drive roller 22 rotates in the opposite direction to the above through the connecting shaft 20. Therefore, the drive runner 18 is
Move the top towards the storage. Then, the partition panel 1 is stored toward the storage. In the storage, the storage stop photoelectric tube 48 is attached to the storage inner wall or the partition panel 1.
The partition panel 1 stops moving when it senses the light reflected by. Similarly, the partition panel 1 is sequentially stored in the storage.

In this case, the number of drive runners 18 may be one, and smooth turning is possible not only in the straight section but also in the corner section 32.

(2) Inner peripheral wall 34 in the turning region 60 of the drive rail 30
The shape of the corner of the drive runner 18 is 270
Although it is supposed to rotate by 90 degrees, it may be rotated by 90 degrees or the like depending on the purpose.

(3) In the above embodiment, the driving rail 30 in the corner portion 32 is formed at a right angle, but it may be formed in a slightly R shape. In this case as well, the drive runner 18
The corner section 32 can be moved smoothly.

(4) Photocell 46 for partition, photocell 47 for stopping travel, photocell 48 for storage stop, photocell 49 for touch-to-contact floor contact in the above embodiment
The installation position of the storage start phototube 50 may be any position such as the front surface, the back surface, or both end surfaces of the partition panel 1, depending on the installation location, shape, purpose of use, etc. of the partition panel 1.

(5) By changing the height of the inner roller 28 and the height of the inner peripheral wall 34 in correspondence with each other, the drive runner 18 can be shifted from a straight running to a branched rail.
