Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coating device for the seam fastening portion of a roof panel. the goby tightening part,
The present invention relates to a trolley-type painting device that can perform painting using a painting roller that is displaced in the front-rear direction.

[Conventional technology]

As a method for joining roof panels in which peaks are formed parallel to each other at appropriate intervals, as shown in FIG. 7, adjacent roof panels 1a and 1b are joined by
A jointing method is employed in which the two panels are overlapped and connected to each other on the upper side of the peak 2 formed between the two panels.

This seam tightening method is carried out at a roof panel installation site using an automatic seam tightening machine that travels over the peak 2, and a seam tightening section 3 that protrudes along the longitudinal direction above the peak 2. can be formed.

When such an automatic seam tightening machine is used, pressure marks of the forming roller often remain as scratches on the left and right side surfaces 4, 4 of the seam tightening portion 3 formed by the forming roller. If these scratches are left as they are, depending on the material of the roof panel, they may cause rust, or even if there is no risk of rust, they may impair the aesthetic appearance.

Therefore, in order to solve this problem, it is necessary to paint the seam tightening part with an appropriate paint. However, in the past, there was no dedicated coating equipment that could efficiently coat this uniquely shaped joint, and the coating had to be done manually with a brush, which took a lot of time and effort.

By the way, Japanese Patent Laid-Open No. 57-35961 discloses that a trolley-type coating machine is self-propelled, and the side surface of a coating roller provided on one side of the trolley is aligned with a vertical plane forming a right angle with the horizontal plane of a fillet weld. By bringing it into close contact,
A device is described that allows fillet welds to be painted.

Then, the painting roller is made to swing along the painting surface faster than the movement of the cart.
As a result, the coating roller moves back and forth in a circular arc, and when it is located at the apex of the arc, the coating roller temporarily deforms greatly and presses against the coating surface with a force of varying degrees of strength, resulting in coating. It can be painted without causing unevenness.

[Problem to be solved by the invention]

However, in order to take advantage of the deformation of the coating roller, a large deformed area must be ensured, and if the swing mechanism is not made small, the cart must be placed on top of the narrow peak that forms the seam tightening part. However, there are some drawbacks that make it difficult to apply, such as the inability to do so.

Furthermore, the seam tightening portion is thin and flat, and does not have large rigidity against lateral forces. Therefore, when a swing-type rocking device is applied to the seam tightening part, there is a risk that the seam tightening part may be deformed, which poses a problem that it is not preferable for painting the seam tightening part.

In addition, as mentioned above, the seam tightening part has not only a flat surface but also a top that must be painted, and the pressure marks of the forming roller of the automatic seam tightening machine that remain on the seam tightening part are the same as those of the seam tightening part. It may vary depending on the height. Moreover, there are special characteristics such as the fact that the heights of the haze tightening parts themselves are not necessarily the same.

Although a conventionally existing simple coating device using two rollers is described in, for example, Japanese Utility Model Application Publication No. 171563/1983, the part to be coated on the object to be coated is unique due to the configuration of the device. The disadvantage is that it does not provide flexibility in changing the painting area.

By the way, when painting the seam tightening part, if only two painting rollers are arranged as described above, the painted surface may shift when the worker moves it manually. Therefore, it is preferable to mount the coating roller on a trolley and run the wheels of the roller along one of the surfaces of the object to be coated, so that the trajectory of the coating roller is maintained at a constant height. Therefore, it is desirable to be able to adjust the height of the coating roller when the height from the copying surface to the coating area differs.

The present invention was made in view of the above problems, and its purpose is to be able to simultaneously paint the flat side surface of the thin seam tightening part and the top thereof, and to provide a structure using a trolley in order to simplify and smooth the painting work. In this case, the painting area is not uniquely regulated on the tracing surface, and the height at which the painting roller is arranged is changed according to the size and height of the seam tightening part, and
The coating roller can be moved back and forth against the painted surface on a moving coating device, without applying unnecessary force to the seam tightening part, and without causing uneven coating or uncoated areas. To provide a coating device for a seam fastening part of a roof panel, which realizes coating of a desired part quickly and reliably.

At this time, since the painting rollers 23a and 23b are reciprocating back and forth, the painting rollers 23a and 23b repeatedly contact and roll on the same part of the seam tightening part 3, resulting in unpainted areas and uneven painting. There is no risk of this occurring. Of course, in order to completely repeat the painting of the same area, it is required that the backward speed of the painting rollers 23a and 23b, that is, the movable body 8, be sufficiently higher than the forward speed of the truck 5.

In the above example, all of the paint supply means are mounted on the trolley, but for example, paint can be supplied from a pump and paint tank unit that are separated from the trolley and made independent, using a long flexible pipe that does not interfere with the movement of the trolley. It may also be configured such that the paint is fed under pressure to the paint dripping unit. Furthermore, the structure of the coating roller is not limited to the above-described example, and therefore, the method of supplying paint to the coating roller may be any method that is compatible with the structure of the coating roller. Furthermore, an operating means for separating the two painting rollers against the biasing force of a spring, a means for fixing both rollers in a separated state, etc. can also be used together.
