Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a welding and painting room in which workpieces can be conveniently transferred between the welding and painting rooms and the air in each room can be purified.

[Background technology]

For example, in buildings using the dry method 1 method, workpieces such as frames that make up architectural panels used as walls, floors, etc.
It is necessary to weld welding members such as joint fittings for the connection. After welding, a paint is applied to the welded part or the entire surface of the workpiece for rust prevention and the like.

Traditionally, such welding and paint application work was performed in separate work areas, which caused problems such as time-consuming transportation between the work areas.
The work efficiency was poor.

It should be noted that smoke is generated during welding, and paint mist is also generated during painting work, so it is necessary to conveniently exhaust the smoke and paint mist outdoors.

(Objective of the Invention) The present invention provides a work transport device that passes through both chambers in a box body having a welding chamber and a painting chamber, thereby making it possible to perform welding and painting operations in a series and eliminate smoke and paint mist caused by welding. The purpose is to provide a welding and painting room that can efficiently discharge waste and improve the working environment.

Further, the relay conveyor 14 has a plurality of guide rollers 16 at its end whose upper end is at the same height as the upper running surface of the endless chain 57.
- and - are arranged side by side at different positions on the front and back sides of the side plate 47 and near the outermost position of the rotating body 55.

The running conveyor 43 has the same structure as the intermediate conveyor 14 except for its shorter length, and is formed as a slat conveyor that moves on rails 42 and 42 and is provided with an endless chain 57 having slats.

The second transport conveyor 12BSfi output conveyor 15 both uses four roller conveyors 41-- similar to the transport conveyor 11.

The welding and painting room 2 has a box body 25 in which the storage room 24, the welding room 21, the compartment 23, and the painting room 22 are arranged side by side as described above.

The box body 25 has a front plate 62, a rear plate 63, and a side #1i64.6.
The rack has a box-like shape with the upper part of the rack 4 covered by an upper slope 65, and a floor plate 67 that separates an underfloor space 66 from the floor surface is horizontally extended between the racks. Also, a middle plate 69.69 that separates the passage 29 is provided on the side plate 64.64, and the rooms 21 to 24 are connected between them.
It is divided into

As schematically shown in FIG. 5, the underfloor space 66 is provided with a base 70, 70 below the middle plate 69, and between the storage chamber 24 and the welding chamber 21 and at the center of the compartment 23. Foundations 71, 72 are provided which also cross the passage 29.

The base 70.70 has openings 75.75.76.76 connecting the underfloor space 66 below the welding room 21 and the painting room 22 and the underfloor space 66 of the passage 29.

In addition, the floor body 67 of the welding room 21 and painting room 22 is provided with two relatively long rows of exhaust ports 31.3132.32 extending laterally, and a screen-shaped ventilation frame is attached to the exhaust ports 31.32. It will be done.

Further, the upper plate 65 is provided with a horizontally elongated ventilation box 92 to which a blower 91,91 is attached at the upper part of the welding chamber 21, and inside the ventilation box 92, the upper plate 65
An air purifier 9 having a filter, etc. in the cutout opening.
3 is installed.

An air purifier 94 is also attached to the upper plate 65 above the painting chamber 22.

The father plate 65 has a pair of exhaust fans 96.9 on each side thereof.
6 are juxtaposed, the ducts 97.97 of which are connected to the passage 29.

Note that each of the gaps G facing the painting room 22 is provided with an air curtain device 102 for shielding the gaps G.

[For production]

Therefore, the work W stored in the storage chamber 24 is moved downstream using the conveyor 11.

Furthermore, by moving the intermediate conveyor 14.14 laterally according to the length of the workpiece W, the worker in the work space S can approach the end of the workpiece W, thus making it easier to weld the welded parts. do.

Also, outside air is forced in from the blower 91 and into the ventilation box 92.
After the air is purified by the air purifier 93, the welding room 21
from the exhaust port 31 to the underfloor space 66' and the opening 7.
6. Through the underfloor space 66, the air is forcibly exhausted outdoors from the duct 97 by the exhaust fan 96, and thus generated in the welding room 21.
Smoke from welding can be removed along with the airflow, keeping the inside of the welding chamber 21 clean.

Further, the welded workpieces are transferred to the first conveyor 1 in the compartment 23.
It is cooled while passing through 2A. Further, the workpiece W is transported to the second transport conveyor 12B, and the workpiece W is transferred to the painting robot 100.
Depending on the method, a painted finish or painting only the welded parts is performed.

Also, in the painting room 22, a duct 97 is opened by driving the exhaust fan 96.
By creating a negative pressure in the underfloor space 66 through the air purifier 94, clean air is sucked in from the air cleaner 94 and flows down in the painting room and the exhaust port 30. Further, the cleaner 99 absorbs the paint mist, cleans it, and then exhausts it.

〔Effect of the invention〕

In this way, the welding and painting room of the present invention forms the welding room and the painting room via a partition, and is provided with a workpiece conveyance device that penetrates each room, and the welding room and the painting room are provided with a floor. While the exhaust port leading to the body is opened, the duct leading to the exhaust fan is connected to the space under the floor, so workpieces can be transported continuously from the welding room to the painting room, eliminating manual movement in between, improving work efficiency. At the same time, smoke and paint mist generated by welding can be efficiently discharged to the outside, improving the working environment and increasing productivity.
