DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive runner which is disposed in a rail provided on an internal ceiling of a building and supports a moving body such as a partition panel for suspending and moving along a rail. It is.

[0002]

2. Description of the Related Art Conventionally, there is a partition panel for partitioning a large space such as a wedding hall into small spaces according to the number of users. The partition panel, which is a moving body, is suspended by a drive runner that moves in a rail provided on a ceiling, and advances or retreats in a suspended state as the drive runner moves. When the plurality of partition panels are stopped at predetermined positions, they are brought into close contact with each other to form a wall and partition the space.

[0003] Generally, a drive runner for transporting a partition panel has a motor inside, and a driving force of the internal motor is transmitted to wheels, and the wheels roll along a rolling surface in a rail. As a result, the drive runner runs on the rails. The control of the operation such as advance, retreat or turning of the partition panel is based on the fact that a photoelectric sensor mounted on the drive runner detects a dog for position detection. That is, the photoelectric sensor detects dogs disposed at predetermined points along the rolling surface, and instructs acceleration, deceleration, and the like in the control unit based on the detection signal.

[0004]

However, the wheels of the drive runner do not always roll smoothly on the rolling surface. For example, when the rail is formed by press working, the rolling surface may not always be formed completely flat. In this case, the wheels roll on the rolling surface while slightly swaying left and right with respect to the traveling direction. Also,
A partitioning panel is suspended from the drive runner, and the partitioning panel swings back and forth and right and left as it moves, so that the drive runner also swings. The surface rolls. On the other hand, since the dog is arranged on the rolling surface in the rail, if the wheel sways as described above, the wheel comes into contact with the dog and the dog is broken, or the dog is dropped. There was a problem.

An object of the present invention is to provide a dog which does not break or fall off even when a wheel or the like on a driving runner comes into contact, and a mounting structure thereof.

[0006]

In order to solve the above-mentioned problems, the present invention is based on the present invention, wherein the present invention is arranged such that a moving body is suspended and supported in a rail, and the moving body is moved along the rail. The gist is that a dog body provided on the rail and having a detected part formed on the top is formed of an elastic material, corresponding to a position detecting device disposed on a driving runner that conveys the driving runner. Further, in the invention according to claim 2, the driving runner which is arranged in the rail to suspend and support the moving body, and conveys the moving body along the rail, on the rolling surface, rolls. The gist of the invention is that a dog with an elastic member interposed therebetween is provided between the detected portion and the mounting base on the side of the wheel.

[0007]

According to the above construction, according to the first and second aspects of the present invention, the detected portion at the dog apex is detected by the detecting device for detecting the position of the driving runner itself. On the other hand, when the drive runner rolls on the rolling surface and sways to the left and right because the elastic member is interposed between the mounting base and its detected part, the wheels etc. stand on the rolling surface from the side. When the dog comes into contact with the dog, the flexible member bends and releases the pressing force due to the contact.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a partition panel driving runner according to an embodiment of the present invention.

First, the overall outline will be described with reference to FIG. Rail T installed on the ceiling of a hall such as a wedding hall
A pair of drive runners R1 and R2 are provided in the inside.
The two drive runners R1 and R2 suspend the partition panel 3 as a moving body via the connecting shaft 15. Rail T
Is a press-formed box having a wide opening at the center of the lower surface along the length direction and a substantially channel-shaped cross section. And
Side pieces on both sides of the opening formed along the back surface of the ceiling 7 of the rail T are referred to as guide rails Ta, and the guide rails T
The upper surface of “a” is a rolling surface 6. A trolley rail 8 is disposed on the upper inner side surface of the rail T along the longitudinal direction. The trolley rail 8 has four trolleys 9
Are arranged. The two drive runners R1 and R2 have an outer shell formed by a substantially rectangular parallelepiped metal body case 4, and two wheels 5 axially mounted on both sides roll on a rolling surface 6 formed on a rail T. By doing so, both drive runners R1 and R2 move along the rail, and transport the partition panel 3 to the partition position. still,
Since both runners R1 and R2 have the same configuration, only the drive runner R1 will be described below, and description of the configuration of the runner R2 will be omitted.

As shown in FIG. 1, the drive runner R1 is mounted on the rolling surface 6 in the rail T. Drive runner R
A current collecting member 11 is disposed at a substantially central position on the surface side of the upper wall 10 of the first main body case 4. The current collecting member 11 is a power supply unit for supplying power from the trolley 9 to the inside of the drive runner R1, and includes four current collectors 12 that are in sliding contact with the corresponding trolleys 9, respectively. Two of the current collectors 12 are used for power supply (AC 100 V), and the other two current collectors 12 are used for multiplex transmission signals (DC 100 V). These current collectors 12 are connected to a control panel 13 in the partition panel 3 by lead wires 16 inserted through the connection shaft 15.
It is connected to the.

A pair of AC geared motors (not shown) are provided inside the main body case 4 of the drive runner R 1, and each of the transmission mechanisms 25 has a tooth clutch 24.
The driving force is transmitted to the small gears 26 which are axially mounted on both outer sides of the main body case 4 via the gears. The transmission mechanism 25 turns on and off the tooth clutch 24 by exciting and degaussing a coil (not shown) inside the transmission mechanism 25, so that the driving force of the motor is connected to or disconnected from the small gear 26. .

A wheel rotation gear 27 is mounted on the axle of the wheel 5 inside the wheel 5, and the wheel rotation gear 27
Is adapted to rotate integrally with the wheel 5.
The wheel rotation gear 27 is meshed with the small gear 26, and is configured to rotate by receiving a driving force of a motor. Therefore, since both wheels 5 are self-propelled drive wheels, the drive runner R1 can move forward and backward by forward / reverse rotation of the motor. It is possible to convert. Further, since the driving force can be turned on and off by the tooth clutch 24, the speed can be easily adjusted. A pair of front and rear guide rollers 28 are mounted on the upper ends on both outer sides of the main body case 4.

A pair of photoelectric sensors 14 as a detecting device is mounted on the lower wall 17 of the main body case 4 at a position facing the left and right guide rail portions Ta. The photoelectric sensor 14 has a detection unit 18 having a light-emitting unit and a light-receiving unit whose lower wall 17 protrudes toward the lower surface side at the tip. A plurality of dogs 19 for detecting the position of the drive runner R1 are provided upright on the inner side of the rolling surface 6. On the top of the dog 19, a reflection plate 20, which is a portion to be detected, that reflects the light emitted from the photoelectric sensor 14 is mounted. The reflection plate 20 is attached to the top of a dog body 21 made of silicone rubber, which is an elastic member. I have. The main body 21 is adhesively fixed at a predetermined position on the rolling surface 6 by a mounting base 22 formed at the lower end. The position of the mounting base 22 of the dog main body 21 is shifted inward from the reflection plate 20, and the reflection plate 20 is positioned closer to the wheel 5. The photoelectric sensor 14 that has detected the dog 19 sends a detection signal such as a detection position or the number of detections to the control panel 13.

A bearing portion 30 is fixed to the lower wall 17 of each main body case 4 at the front and rear, and a rotation shaft 32 of a swing member 31 is supported. The tip side of the swing member 31 is the lower wall 15 of the main body case.
Is projected downward from the hole 33 provided in the
By rotating around the rotation shaft 32, the wobbling movement of the partition panel 3 and the drive runner R1 when moving is absorbed. Hanging bolts 34 are provided on the back surface of the swinging member 31.
The suspension plate 35 formed with a projection is fixed by a fixing bolt 36.
It is fastened by. The suspension bolt 34 is connected to the connection shaft 15 protruding above the partition panel 3,
The partition panel 3 is suspended via the connecting shaft 15. Note that a guide roller 37 serving as a guide when the drive runner R1 rotates is mounted on the suspension plate 35.

The partition panel 3 which is a moving body has a height of about 3
m, a width of about 1 m, and a thickness of about 10 cm.
An upper surface cushion 38 is mounted on the upper surface, and a lower floor cushion (not shown) is mounted on the lower surface. And
When the partition panel 3 is placed at the partition position, the ceiling cushion 38 comes into contact with the ceiling by the ceiling-contacting mechanism (not shown), and the floor cushion comes into contact with the floor. As a result, the partition panel 3 is firmly fixed, and the shielding effect is enhanced.

Next, the operation of the two drive runners R1 and R2 using the dog 19 and the mounting structure will be described. The drive runners R1 and R2 mounted on the rolling surface 6 in the rail T move in the rail T by rolling the rolling surface 6 by driving the wheels 5. Here, when the rolling surface 6 is not completely flat, or when the partition panel 3 swings with the movement of the drive runners R1 and R2, the drive runner R
Wheels 1 and 2 are provided with unevenness of rolling surface 6 and partition panel 3.
It moves while swaying left and right with the sway of. Here, dog 1 with wheels 5 of drive runners R1, R2 just
At the position 9, it swings right and left and contacts the reflection plate 20 of the dog 19. Then, a lateral pressing force is applied to the dog 19. Since the main body 19 is a flexible member made of silicone rubber, the dog 19
Deflects elastically and releases the pressing force. When the wheel 5 separates from the reflection plate 20, the main body 19 returns to the original position again by the elastic force of the rubber.

With this configuration, the following effects can be obtained. (I) Even if the wheels 5 of the drive runners R1 and R2 just swing right and left at a certain dog 19 and come into contact with the reflection plate 20 of the dog 19, the pressing force is released by the elasticity of the main body 19, so that the reflection plate 20 Will not break. Also,
Since an excessive load is not applied to the mounting base 20, the dog 19 does not fall off. (Ii) The dog 19 that has once bent and released the pressing force is the wheel 5
As soon as there is no contact with the main body 19, it returns to its original position by the elastic force of the main body 19, so that the detection of the photoelectric sensor 14 is not hindered. (Iii) Since the reflection plate 20 is unlikely to be broken, it is possible to use a material having relatively low strength as compared with the related art.
Similarly, as the adhesive for fixing the dog 19, an adhesive having relatively low adhesiveness can be used. (Iv) Since the mounting base 22 of the dog 19 is located more inside than the position of the reflection plate 20, the mounting work of the dog 19 on the rolling surface 6 becomes easy, and the mounting base 22 after the installation and the rolling are rolled. It becomes easy to confirm the adhesion state with the surface 6.

Although one embodiment of the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and may be embodied in other modes as described below. (1) In the above embodiment, the elastic member dog body 21 is made of silicone rubber, but may be made of other natural or synthetic rubber. For example, butadiene rubber, styrene-butadiene rubber, chloroprene rubber and the like can be mentioned. Also,
As shown in FIG. 4, the dog main body 40 may be constituted by a coil spring. It is easy to change the strength of the coil spring by changing its diameter or thickness. (2) In the above-described embodiment, the reflection plate 19 of the dog 19 and the mounting base 22 are located at shifted positions. However, the reflecting plate 19 may be set upright. (3) The movable body in the present invention is a partition panel 3
Is used, as long as it is supported by the drive runners R1 and R2, and this can be applied to a crane or the like, or a lift having a seat for carrying a person. (4) In the above embodiment, the detection device is a photoelectric sensor. However, it is needless to say that the detection device can be applied to another detection device such as a proximity sensor. In this case, an iron plate may be used instead of the reflection plate 20. (5) In the above embodiment, the main body 20 is integrated with the mounting base 22, and all parts except the reflection plate 20 are made of an elastic member made of silicone rubber. However, since it is sufficient that the pressing force of the wheel 5 in the lateral direction can be released, it is not necessary that the entire dog body be an elastic member. (6) In the above embodiment, the dog is set up on the rolling surface 6, but it is not always necessary to be on the rolling surface 6 depending on the position of the sensor. The same effect is obtained when the main body case 4 comes into contact other than the wheels 5 of the drive runners R1 and R2. Alternatively, only the mounting base 22 may be configured separately. The number of the drive runners R1 and R2 may be one or three or more. The shape of the rail T can be appropriately changed according to conditions such as the weight of the drive runners R1 and R2 and the size of the room. In addition, the present invention can be freely modified and implemented without departing from the gist thereof.

[0019]

As described above in detail, according to the dog or the dog mounting structure of the present invention, when a pressing force is applied to the dog by the wheels of the drive runner, the elastic member releases the pressing force to the dog. Problems caused by stress concentration are eliminated.
