[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for driving a work moving apparatus for performing operations such as moving, transporting and mounting various works.

[0002]

2. Description of the Related Art Generally, as operation switches for machinery,
A push button switch, a toggle switch, a sheet switch, or the like is often used. Even if a wired or wireless remote control method is adopted in consideration of workability,
Any of the switches described above is used for the operating device.
Any of the above switches has been used in an operating device for operating a drive of a work moving device for performing operations such as moving, transporting, and mounting various works.

[0003]

By the way, in a conventional work moving apparatus for performing operations such as moving, transporting and mounting various works, when a switch of the operating apparatus is fixed to the work moving apparatus, the operating apparatus is not operated. Since the operator cannot move away from the work moving device, he cannot perform any operation other than the driving operation.

On the other hand, even when the driving operation is performed by a remote control method, a push button switch, a toggle switch, or
The operating device on which the seat switch and the like are arranged must be at least a certain size, and the operator of the operating device always has both hands or one hand restrained by the operating device,
After all, work other than the driving operation could not be performed. Therefore, when performing operations such as moving, transporting, and mounting various works using the work moving device, in addition to the number of workers required for the work, the operator of the operating device responsible for only the driving operation is required. Was needed.

[0005] Further, when performing operations such as moving, transporting and mounting various works using a work moving device, it is necessary to exchange operational signals between the operator of the operating device and the operator. It is indispensable, and if communication between the operator and the operator is lacking, the workability is reduced, which may result in unsafe work. Therefore, the operator of the operating device and the operator need to be located as close as possible in order to reliably exchange operational cues. It was restrained and reduced operability and workability.

As a method for solving the above-mentioned problems, a method has been considered in which the operating device is made as small as possible and temporarily installed using a magnet or the like in the vicinity of the work section and the operator himself operates the operating device while working. , When the work range is wide, or when it is necessary to work while moving,
It was impossible for the operator to operate the operation device while working himself, and the effects of reducing the number of personnel engaged in the work, improving workability, and improving safety could not be expected.

[0007] The present invention has been made in view of the above circumstances, and even when the working range is wide or when it is necessary to work while moving, the operator of the operating device is restrained by the operating device. It is an object of the present invention to provide a method and an apparatus for driving a work moving device using a line switch that enables operations other than the driving operation without being performed.

[0008]

According to a first aspect of the present invention, there is provided a method for driving a work moving apparatus using a line switch, wherein the work is supported by the work moving apparatus and is fixed. When reaching the position, the driving operation of the work moving device is performed by a line switch connected to a driving unit of the work moving device, and the line switch is detachably attached to the work or a peripheral portion thereof. The drive operation of the work moving device is performed by operating the line switch.

According to a second aspect of the present invention, there is provided a drive operating device for a work moving device using a line switch, wherein the driving portion drives the work moving device which supports the work and reaches a fixed position, and is connected to the drive portion. And a line switch for operating the drive of the drive unit, wherein the line switch is detachably attached to the work or its peripheral part.

The drive unit 6 is connected to the air bearings 8, 8 # so that signals are transmitted. The cord 27 # is bundled together from the viewpoint of workability and maintainability, and is covered with a protective spiral 29.

The dimensions of each part constituting the operation unit 20a are as follows.
For example, the thickness of the base plate 25 is 3 mm, the thickness of the sheet magnet 26 is 3 mm, and the thickness of the operation unit 20a is about 15 mm. The operation unit 20a including three line switches 21, 22, and 23 arranged side by side on one plane has a width of about 52 mm.

The operation section 20a must be arranged over the entire range in which the operator pushes and pulls the work 2 in order to adjust the horizontal position during the final positioning work of the work 2. Operation unit 20 according to the size of 2
The length of a is set. For example, if the work 2 has a length of 3.2
m, 1.6m width ceiling frame,
The length of the operation unit 20a is set to 1 m, and sheet magnets 26 for detachably attaching the operation unit 20a to the work 2 or its peripheral portion are attached to three places of the operation unit 20a.

Further, when the work 2 is larger than a certain size as in the case described above, a plurality of workers are required to perform the mounting work, and therefore, it is preferable to arrange the operation section 20a at a plurality of places. When the operation unit 20a is arranged at a plurality of places, as shown in FIG. 1, the signal transmission cords 27 # wired to the three line switches 21, 22, and 23 that constitute each operation unit 20a , Joint 30, one cord 27 wired to each line switch 21, one cord 27 wired to each line switch 22, and one cord 27 wired to each line switch 23.
Performs signal transmission to the sequencer 28 which is integrated into the transporter 1 for ceiling work. That is, the plurality of operation units 20a are connected in parallel at the joint 30. Hereinafter, in this embodiment, the number of workers is two, and the operation units 20a are arranged at two places, one at a time within the range where each worker pushes and pulls the work 2.

The length of the cord 27 # for transmitting signals from the three line switches 21, 22, and 23 constituting the operation unit 20a to the transporter 1 for ceiling work is determined by the length of the work 2 on which the operation unit 20a is mounted. It is necessary to have a sufficient length to raise it to a mounting position at a high place such as a ceiling.
The length is about 3 m.

Hereinafter, the work of mounting the work 2 to a high place such as a ceiling using the transporter 1 for ceiling work will be described. First, the work 2 is placed on the work table 4 of the transporter 1 for ceiling work via the work holding mechanism 7,
The operator 40 boards the operator boarding platform 11. The operator 40 operates the operating device 13 to move the self-propelled trolley 3 to a position immediately below a predetermined mounting position to roughly perform horizontal positioning, and then to place the work table 4 at a high mounting position such as a ceiling. To the vicinity of.

The driving operation of the ceiling work transporter 1 after the rough positioning of the work 2 is completed by the above operation is performed by the driving operation device 20 of the work moving device using the line switch of the present invention. That is, the operation is performed by attaching the operation unit 20a to the work 2 and operating the operation unit 20a.

The operating device 1 is mounted on the operator mounting base 11.
Thereafter, the operator 40 who has operated the work 3 is engaged in the work of attaching the work 2 as another worker together with another worker who is waiting. First, the two workers ride on a stepladder or an aerial work vehicle arranged in the vicinity of the work 2 and arrange the work 2 for mounting.

Next, the operation unit 20a is operated to turn on the air bearings 8, 8 #. By this operation, air is pressure-fed from a pressurizing source (not shown) to the air bearings 8, 8 # via the air hose 9, and an air film is formed between the work table 4 and the work holding mechanism 7. This air film reduces the frictional resistance to 2-3 / 1000, so that several hundred kilograms of the work 2 can be moved in the horizontal direction with a small force.

The two workers adjust the horizontal mounting position by pushing and pulling the work 2 by hand, but the operation unit 20a is arranged over the entire range in which the worker pushes and pulls the work 2. The worker himself / herself checks the horizontal position of the work 2 and pushes and pulls the work 2 by hand to adjust the horizontal position of the work 2 without releasing the hand from the work 2 By operating the operation unit 20a with the operation of one finger, the operation of slightly raising / stopping the work table 4 or the operation of slightly lowering / stopping the work table 4 can be performed.

The operator places the work 2 at a predetermined position in the horizontal direction, raises the work table 4 and places the work 2 at a high mounting position such as a ceiling, and then moves the work 2 in the horizontal direction. By operating the operation unit 20a while holding the hand so that the position does not fluctuate, the air bearings 8, 8 # are turned off to fix the position of the work 2. Thereafter, the operation unit 20a is detached from the work 2 and attached to the work table 4 or the like, and the operation is shifted to a work of attaching the work 2 to a high mounting position such as a ceiling. After the completion of the mounting operation, the work table 4 is lowered and the operation for mounting the next work 2 is started.

As described above, the operation unit 20a is provided with the work 2
Can be arranged over the entire range pushed and pulled by the worker when performing the adjustment work of the horizontal position of....
Since there is no protrusion, erroneous operation is unlikely to occur, so the operator himself pushes and pulls the work 2 to adjust the horizontal mounting position, and operates with one finger without releasing the hand from the work 2 The unit 20a can be operated. Therefore, an operator of the operating device that is in charge of only the driving operation is not required, and the number of personnel can be reduced.

For example, in the installation work of the ceiling / equipment unit, three to four persons in total, two to three workers in addition to one operator of the operating device 13 which is conventionally in charge of only driving operation, are used. By adopting the method and apparatus for driving the work moving device using the line switch according to the present invention, the operator of the operating device 13 can perform the work after the rough positioning of the work 2 is completed. The operator can participate in the installation work as a worker, so that the work can be performed by a total of two personnel including one other worker.

Further, the worker himself / herself adjusting the horizontal position of the work 2 by pushing and pulling the work 2 manually checks the horizontal position of the work 2 while operating the operation unit 20a. Since the operation is performed, it is not necessary to exchange an operation signal between the operator of the operating device and the operator, which is indispensable in the past, and the workability is greatly improved and the safety is also improved.

In the above embodiment, the operation unit 2
Numeral 0a is composed of three line switches 21, 22, and 23, each of which is an operation of slightly raising / stopping the work table 4, an operation of turning on / off the air bearings 8, 8 #, and a slightly lowering / stopping of the work table 4. However, the driving operation of the transporter 1 for ceiling work, which can be controlled using the operation unit 20a, is not limited to the above three types of operations, and can be used for controlling other driving operations. It is.
Further, by appropriately increasing or decreasing the number of line switches constituting the operation unit 20a, the number of driving operations of the transporter 1 for ceiling work controlled by the operation unit 20a can be increased or decreased.

In the above embodiment, the operation unit 2
Although the length of 0a is set to 1m, the length of the operation unit 20a depends on the size of the work to be handled by the worker or the width of the work range when the worker needs to work while moving. Just set it. Similarly, the number of bases for arranging the operation unit 20a is two in the above embodiment, but may be appropriately increased or decreased according to the case.

Further, in the above embodiment, the operation unit 2
The sheet magnet 26 is attached to the operation unit 20a in order to detachably attach the operation unit 20a to the work 2 or its peripheral portion. However, for example, the use of a temporary fixing jig is also conceivable.

Furthermore, in the above embodiment, the work moving device driven and operated by the operation unit 20a is the transporter 1 for ceiling work, but the work moving device using the line switch of the present invention of the present invention. The application target of the drive operation method and apparatus of the present invention is not limited to the transporter 1 for ceiling work, and can be applied to the drive operation of various other work moving devices.

As described above, the operating portion 20a of the drive operating device of the work moving device using the line switch is manufactured from inexpensive material by simple processing, has a simple structure, is not damaged even by a large external force, and is applicable. Is very practical.

[0037]

According to the method and the apparatus for driving a work moving device using the line switch of the present invention, the line switch is attached to the work or its peripheral portion and is long, so that the line switch can be used by the worker. Is operated without departing from the work position, so that the drive unit can drive and operate the work moving device. Therefore, the worker can perform work without being restricted by the driving operation, so that workability can be significantly improved. In addition, since the line switch is thin, the line switch can work smoothly without obstructing the movement of the work.
