Abstract

PURPOSE:To miniaturize a motor-driven runner and increase driving forces for the runner by integrating a runner body having plural driving rollers, the driving portion of the main body, an electricity collecting mechanism and a partition hanging into one structure. CONSTITUTION:Six driving rollers 12 each having a gear 12c provided on the back face thereof are axially attached to both sides of a runner main body 11. The main body 11 is provided with a hollow hanging bolt 13 and a sleeve 13c which is threadbly engaged in the bolt 13, to hang a partition panel P. A transmission shaft 14 is passed through the hanging bolt 13 and is connected at its lower end to the extension shaft 15 of a motor and all the rollers 12 can be driven by a gear mechanism. Further the main body 11 is provided with a blush 17 and a guide roller 18 to form a motor-driven runner 10. The runner 10 is disposed in front of and behind the upper edge of the panel P and electricity is collected from a trolly wire TW so that the runner 10 travels on a hunger rail HR. The runner can thus be miniaturized and also made strong enough to stably travel.

Description

[Detailed description of the invention] Industrial applications This invention uses a motor C to move a large partition panel.

Therefore, the present invention relates to an electric runner for a movable partition that is electrically driven.

Conventional Technology Event facilities such as hotels and halls use large partition panels that are movably suspended from hanger rails installed on the ceiling via runners, allowing the facility to be partitioned as desired. One of the partitioners is busy.

Partition panels for movable partitions are several meters high and 10 meters wide.
As mentioned above, there are few large ones with a weight of 1 or more, so recently there is a strong demand to electrify them.Therefore, a motor is built into the top of the partition panel and this motor is used to drive the runner. , a technique has been proposed in which the runner is an electric runner (for example, Japanese Patent Laid-Open No. 2-30875).

The electric runner in this product has a stacked structure of upper and lower layers, the lower part is a hanging runner having support rollers for suspending the partition panel, and the upper part is a driving roller having a driving roller. It is a runner for use. The drive roller is connected to the motor via a transmission shaft, and contacts the top surface of the hanger rail to make the whole run, while the support roller rolls on the bottom surface of the hanger rail and supports the weight of the partition panel. There is.

Problems to be Solved by the Invention In the conventional technology, since the electric runner has a stacked structure of upper and lower layers, the height in the vertical direction becomes high.
There was a problem that the required cross-sectional area of Hungarian Rail became large. Further, since the drive roller has a structure in which the drive runner is pushed up by a spring or the like and brought into contact with the upper surface of the runner rail, there is an unavoidable drawback that the drive force of the runner may be insufficient.

Therefore, in view of the problems of the prior art, an object of the present invention is to minimize the required cross-sectional area of the hanger rail by making the entire runner an integral structure, and by making the drive roller also serve as a support roller. To provide an electric runner for a partition panel that can stably obtain a driving force.

Means for Solving the Problems The present invention has a structure in which a runner body has a plurality of driving rollers on both sides thereof, and a partition panel is rotatably hung from the lower surface of the runner body. A hollow suspension bolt to be suspended, a transmission shaft that is inserted through the suspension bolt and connected to the motor in the partition panel, a gear mechanism that connects the transmission shaft and the drive roller, and a current collector located on the top of the runner body. The gist is to have a mechanism.

Note that the gear mechanism may transmit the rotation of the transmission shaft to all drive rollers.

Further, the transmission shaft can also be connected to the motor via a telescoping mechanism.

Effect: With such a configuration, the drive roller can support the partition panel via the runner body and the hanging bolt, and the drive roller is coupled to the motor via the gear mechanism and the transmission shaft. By starting the motor, the entire vehicle can be moved stably.

When the gear mechanism transmits rotational force to all drive rollers, each drive roller can be actively driven at the same time,
Since it is possible to realize so-called all-wheel drive, there is no risk that the overall running performance will be impaired, even when, for example, the vehicle crosses a break in the Hunger Rail at a branch point in the Hunger Rail.

If the transmission shaft and the motor are connected via the telescoping mechanism, the telescoping mechanism expands and contracts while maintaining the connection between the transmission shaft and the motor, so the height of the partition panel relative to the hanging bolts can be freely adjusted.

Example Examples will be described below with reference to the drawings.

Such electric runners 10 are assembled into a partition panel P as a set of two (FIG. 5), and the partition panel P can be moved and run along the Hunger rail HR.

The partition panel P has a surface material P2 on both sides of the frame P1.

A trolley wire TW is provided at the top of the Hunger rail HR (FIGS. 5 and 6).

The Hungarian Rail HR is a long profile member in which the electric runner 10 can run. Hunga Rail HR connects a pair of rail bodies HRI and H through an upper connecting member HR2.

Good (Figure 8).

The Hungerail HR as a whole shall be attached to the lower surface of the structural material of the building and laid on the ceiling surface of the building.

- Since power can be supplied to the motor M via the cable 17c, the electric runner 10 can run back and forth and move the partition panel P by the motor M.

The rotation of the motor M is caused by the extension shaft 15 and the coupling member 15.
This is because the rotation of the transmission shaft 14 is simultaneously transmitted to all the drive rollers 12, 12, . . . via the gear mechanism, as described above. At this time, the control device C is installed in the partition panel P (Fig. 5), and a control signal from the outside is transmitted to the control device C using a pair of conductors TWI, TWI. . In addition to sending a forward command and a backward command to the motor M, the control device C can also optimally adjust and control the output torque of the motor M by adjusting the voltage applied to the motor M, for example.

The electric runner 10 can change its running direction via a rotary device 2o installed in the middle of the Hungerail HRSHR (FIG. 7).

The rotary device 20 has almost the same shape as the Hunger Rail HR, and consists of a rotating part 21 located at the same height as the Hunger Rail HRSHR, and a fixed part 22 that supports the rotating part 21 from above. A short trolley wire TW is disposed so as to be continuous with the trolley wire TW of Hunger Rail HR, -HR. However, each trolley wire TW on the rotary device 20 side and the Hungerail HR side has an electric runner 1 at each end.
A guide member TW4 is attached for guiding the brushes 17, 17, . . . 0 (FIG. 8).

The guide member TW4 has conductors TWI, TW on its lower surface side.

b, 21b, and a thrust bearing 21c.

A worm wheel 21d is fitted onto the upper end of the shaft 21a, and a worm 21e driven by a motor (not shown) meshes with the worm wheel 21d. Further, the fixing part 22 includes a bracket 22a', a spacer 22b
, 22b, by bolt 22 Cs 22 c,
It is fixed to the top of Hungerail HRSHR.

... are arranged so as to be able to slide freely. When the lower ends of the actuator rods 23, 23 come into contact with the dog 16e of the electric runner 10, they move upward, and the limit switch LS is activated.

LS... can be operated. Further, an arm 21d1 is provided protruding from the worm wheel 21d, and another limit switch LSa can be operated by a dog 21d2 at the tip of the arm 21d1.

The electric runner 10 that has advanced along one of the hangarails HR enters the rotating section 21 and is stopped at an appropriate position in the center thereof. At this time, if it is detected via the dog 16e that only the central one of the actuator rods 2B, 2B... is raised by the operation of the corresponding limit switch LS, the electric runner 10 can easily stop at the appropriate position. be able to.

Next, when the worm 21e is rotationally driven, the rotating part 21 can be rotated in the horizontal direction via the worm wheel 21d and the shaft 21a, and the rotation angle at this time can be detected by the limit switch LSa. Therefore, if the rotating part 21 is rotated by a predetermined angle and the electric runner 10 is restarted, the electric runner 10 will become the Hungerail HR.

It is possible to change direction and proceed in the direction of a branch road (not shown) in a direction different from the HR direction. Note that since the trolley wire TW is also disposed on the upper surface of the rotating section 2, the electric runner 10 can freely stop and start not only along the hanger rail HR but also inside the rotating section 21. I can do it.

Since two electric runners 10.10 are used for the partition panel P, in order to change the direction of the partition panel P, the front electric runner 10 and the rear electric runner 10 are used.
In contrast, the direction changing operations by the rotary device 20 may be performed individually and sequentially.

Furthermore, at this time, the running speeds of the front and rear electric runners 10.10 do not become the same due to the rotation of the partition panel P, so if the same driving torque is generated,
There is a possibility that unexpected stress may be applied to one electric runner 10. Therefore, while the partition panel P is turning, the driving torque of the electric runner 10 on the higher running speed side is increased, that electric runner 10 mainly turns the partition panel P, and the other electric runner 10 is
It is preferable to operate so as to follow this.

Further, when the electric runner 10 is viewed from above, any drive rollers 12 and 12, including at least two drive rollers 12 and 12 located diagonally on the runner body 11, may be simultaneously driven. As described in detail, according to the present invention, the runner main body having the drive roller, the suspension bolt, the transmission shaft, the gear mechanism, and the current collection mechanism are combined into one body, resulting in a compact integrated structure as a whole. Moreover, since the drive roller also serves as a support roller,
Since the required cross-sectional area of the hanger rail is kept to a minimum and a plurality of drive rollers can be driven at the same time, a strong driving force can be stably obtained, which is an excellent effect.
