[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to a work floor used when a worker on the floor manually performs manual work from below on the bottom of a workpiece that is being supported and transported by a suspended transport device, for example. It is related to the device.

0002

2. Description of the Related Art Conventionally, for example, a hanging conveyance device has a structure as seen in Japanese Utility Model Application No. 59-131357. That is, a trolley guide rail is installed on the ceiling side, and a conveyed object support device is provided on the trolley device that is supported and guided by the trolley guide rail. A trolley drive rail is installed above the trolley guide rail, and a trolley drive device is supported and guided by the trolley drive rail.

According to this conventional configuration, by interlocking the trolley drive device with the trolley device, the trolley device can be supported and guided by the trolley guide rail, and the transported object can be supported by the conveyed object support device integrated with the trolley device. It is possible to transport objects on the transport route. Then, the worker on the floor can perform the desired work on the bottom of the object to be transported from below.

0004

However, according to the above-described conventional structure, the trolley guide rails are arranged at a constant level and the objects to be conveyed are conveyed at a constant height.
Due to the height of the worker or the work position of the transported object, the assembly work must be performed in an awkward position.
This not only led to industrial accidents, but also led to discrimination among workers due to height differences, and the unreasonable posture made it impossible to perform work quickly and accurately.

[0005] An object of the present invention is to provide a work floor device that allows the worker to perform various tasks while always maintaining a suitable posture, regardless of the worker's height or the work position of the workpiece. It is in.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a working floor device of the present invention includes a plurality of working floors arranged below a transport path for supporting and transporting a workpiece and along this transport path. At the same time, a lifting device is provided to raise and lower each of these working floors separately, and a relay floor is provided between the adjacent ends of each working floor so as to be relatively swingable, and the free end is a fixed floor at the remaining end of each working floor. A slope that can freely come into contact with is connected so as to be able to swing up and down.

[0007]

[Operation] According to the configuration of the present invention, the worker operates the lifting device to raise and lower the work floor while knowing his own height and work position in this work process. The floor can be brought to the most desirable level. Therefore, the operator can perform the desired work on the workpiece being transported on the transport path while always maintaining a suitable posture.

[0008] As each work floor is raised and lowered individually, a difference in level tends to occur between the edges of adjacent work floors, but this can be absorbed by the relay floor that relatively swings according to the difference in level. Workers can use the transfer floor to walk between work floors without tripping. In addition, a level difference will occur between the end of the work floor and the fixed floor, but this can be absorbed by a slope that swings up and down according to the level difference, so that the worker can use the slope to Able to get on and off the work floor without tripping.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a hanging conveyance device, which includes a trolley guide rail 2 installed on the ceiling side, a trolley device 3 supported and guided by the trolley guide rail 2, and a support device (hanger device) provided at the bottom of the trolley device 3. ) 4, a drive device rail 5 installed above the trolley guide rail 2, and a drive device 6 supported and guided by the drive device rail 5.

The support device 4 supports a car body 7, which is an example of an object to be processed, and transports the car body 7 on a fixed transport path 8. A pit 9 is formed below the transport path 8 along this transport path 8, and the outside of this pit 9 serves as a fixed bed 10. In the pit 9, a plurality of flat work floors 11 are arranged along the conveyance path 8, and each work floor 11
The part marked is the work process section.

Each of the working floors 11 can be raised and lowered, and a lifting device 12 for raising and lowering the working floors 11 individually is provided in the pit 9. That is, in each work process section, a base frame 13 is disposed within the pit 9, and the work floor 11 is disposed on the base frame 13 so as to be movable up and down via a pair of left and right pantograph mechanisms 14. A plurality of cylinder devices 15 are arranged between the base frame 13 and the work floor 11. By these 13 to 15, the elevating device 12
Configure.

Furthermore, a pedal-type operating tool 16 for operating the elevating device 12 is provided on the work floor 11, and this operating tool 16 may be provided outside the work floor 11 or the like. Further, a plurality of stopper devices 17 are arranged on the base frame 13 to abut the lower surface of the work floor 11 from below to regulate the lowering limit of the work floor 11, and these stopper devices 17 are mechanically adjustable. configured.

A flat intermediate floor 20 is provided between adjacent ends of the work floor 11 so as to be able to swing relative to each other. That is, one end of the relay floor 20 is connected to one of the work floors 11 via a horizontal axis 21 in the left-right direction so as to be able to swing vertically, and the other end of the relay floor 20 is connected to a horizontal axis 22 in the left-right direction. It is connected to the other work floor 11 via the elongated hole 23 so as to be able to swing up and down relatively.

Furthermore, a slope 24 is connected to the remaining end of each work floor 11 so as to be able to swing up and down. That is, the flat plate-shaped slope 24 has its base end connected to the end of the work floor 11 via the front-rear shaft 25 so as to be able to swing up and down relatively.
A roller 26 provided at the free end of the slope 24 is supported and guided by a guide rail 27 provided on the fixed bed 10 side and becomes movable.

The operation of the above embodiment will be explained below. For example, before starting work in the morning, a worker operates the lifting device 12 to raise and lower the work floor 11 while knowing his/her own height and work position in this work process. That is, the worker moves onto the work floor 11 and operates the operating tool 16 with his/her foot to cause the cylinder device 15 to extend and contract. As a result, the work floor 11 is raised and lowered while maintaining parallelism via the pair of pantograph mechanisms 14, thereby making it possible to bring the work floor 11 to the most preferable level.

In this state, the trolley device 3 moves while being supported and guided by the trolley guide rail 2 as the drive device 6 is interlocked with the vehicle body 7 supported by the support device 4.
can be transported on the transport path 8. Therefore, as mentioned above, since the work floor 11 is set at the most preferable level, the worker can perform the desired work while always maintaining a suitable posture with respect to the vehicle body 7 being transported on the transport path 8. can be done.

[0017] During the work, the operator must use the operating tool 16.
The level of the work floor 11 can be arbitrarily adjusted by stepping on the button. Further, a locking device (not shown) is provided to prevent the work floor 11 from being raised or lowered unexpectedly due to the operator inadvertently stepping on the operating tool 16.

As described above, by raising and lowering each work floor 11 individually, a difference in level tends to occur between the ends of adjacent work floors 11. This means that one end of the relay floor 20 is
It swings up and down relative to one working floor 11 via the horizontal shaft 21, and the other end of the relay floor 20 swings up and down relative to the other working floor 11 through the horizontal shaft 22 and the elongated hole 23. It can be absorbed through this relay bed 20 by moving up and down relative to each other. Therefore, the worker can use the transfer floor 20 to walk between the work floors 11 without stumbling.

[0019] Furthermore, a level difference is likely to occur between the end of the work floor 11 and the fixed bed 10. This is because the base end of the slope 24 swings up and down relative to the end of the work floor 11 via the front-rear shaft 25 according to the difference in level, and the roller 26 provided at the free end of the slope 24 moves against the guide rail. By moving while being supported and guided by 27, it can be absorbed through this slope 24. Therefore, the worker uses the slope 24 to
It is possible to get on and off the work floor 11 without tripping.

In the above embodiment, the trolley device 3 and the drive device 6
Although the suspended conveyance device 1 is shown, it may be a monorail type in which a support device 4 is provided on a self-propelled vehicle that runs while being supported and guided by rails.

[Effects of the Invention] According to the present invention having the above configuration, the worker can:
By raising and lowering the work floor by operating the lifting device while knowing your own height and working position in this work process, you can bring the work floor to the most favorable level, and therefore The operator can perform the desired work on the workpiece being transported along the route while always maintaining a suitable posture. Therefore, work can be performed more quickly and accurately without causing industrial accidents and without causing discrimination among workers due to height differences.

[0022] As each work floor is raised and lowered individually, a difference in level tends to occur between the ends of adjacent work floors, but this can be absorbed by the relay floor that swings relative to each other in accordance with the difference in level.
Therefore, the worker can use the transfer floor to walk between the work floors without stumbling. In addition, a difference in level tends to occur between the edge of the work floor and the fixed floor, but this can be absorbed by a slope that swings up and down according to the difference in level, so workers can use the slope to , you can get on and off the work floor without tripping.
