Description

[Detailed description of the invention] The present invention is based on the method of filling sand into the concave surface of the uneven patterned surface of the decorative surface of an architectural panel with a box-shaped cross section. The present invention relates to a wiping device useful in an intermediate process of manufacturing panels.

More specifically, when filling and fixing sand to the concave surface of a decorative surface, the adhesive or the paint that functions as an adhesive and coating film is applied to the entire surface of the decorative surface, but it is not concave, that is, it exists on the convex surface. This invention relates to a device useful for wiping off paint, etc.

For example, the manufacturing of architectural panels as shown in FIG. 1 was mostly done manually.

With this method, it is difficult to achieve high work efficiency, cost, and uniform quality.

Also, when wiping paint etc. on the convex surface via the roller, the second
As the female part deforms as shown by the two-dot chain line in the figure,
In this area, there was an inconvenience that the paint etc. on the concave surface was also wiped off.

The present invention eliminates these drawbacks, and one embodiment of the wiping device according to the present invention will be described in detail below with reference to the drawings.

FIG. 3 is an explanatory diagram showing the principle of the above-mentioned device, and numeral 1 denotes a guide roller, which is formed into a step-like outer shape that corresponds to the cross-sectional shape of the object A to be wiped to some extent.

The object to be wiped A has a decorative surface C with an uneven pattern in which a concave surface a and a convex surface are randomly arranged, and also has a side wall d, an insertion edge e, an insertion groove (female part) f, and an extension part g. This is an architectural panel with a box-shaped cross section.

Reference numeral 2 denotes a wiping roller which supports the guide roller 1 and the object to be wiped A so as to have a gap through which the guide roller 1 and the object to be wiped A can pass through while rolling in contact with the wiping roller without causing deformation.

The outer peripheral layer of the wiping roller 2 is made of a material having high elasticity and high frictional resistance, such as rubber.

3 is a dampening roller that applies cleaning agent 4 to the outer peripheral surface of the wiping roller 2 by rolling or contacting the same.

As the material of the dampening roller 3, metal or the like is sufficient.

Further, when the wiping roller 2 and the dampening roller 3 are brought into contact, the contact is made with a gap sufficient to cause capillary action, and the number of rotations is the same as that of the wiping roller.

The cleaning agent 4 has characteristics such as the ability to dissolve adhesives, paints, etc., and its vaporization rate to a certain extent.

That is, it has the property of being able to dissolve or wash away paint or the like that adheres to the wiping roller while it rotates about 3 to 20 cm around the outer periphery.

Specific examples include toluene, thinner and other solvents.

Reference numeral 5 uses a doctor knife to prevent the cleaning agent 4, paint, etc. present on the outer peripheral surface of the wiping roller 2 from being led out to the unwiped surface.

This doctor knife 5 rotates in the direction of the arrow around a fulcrum 6, and the contact pressure is adjusted by a weight 7.

Note that the contact between the doctor knife 5 and the wiping roller 2 is such that there is no gap.

Reference numeral 8 denotes an auxiliary roller which, as shown in FIG. 3, conveys the insertion edges and extensions of the male and female parts of the construction panel while imparting elasticity.

The purpose of this roller 8 is to prevent deformation as shown by the two-dot chain line in FIG.

In other words, this is to prevent the finished product from exhibiting its original appearance unless silica sand is attached to both ends of the decorative surface.

In other words, the convex surface of the uneven surface has no paint or the like at all, and only the concave surface has paint or the like, so that the homogeneous surface is in the state before the sand is sprinkled.

Note that the conveying guide roller 1 and the auxiliary roller 8 are set at the same circumferential speed.

This is to prevent slippage from occurring with the object A to be wiped.

Next, the operation of the device according to the present invention will be explained in detail. First, the object A to be wiped has a cross section as shown in FIG.

The uneven pattern on the decorative surface is a pattern as shown in FIG. 1, and the depth h is about 0.3 to 0.9 mm.

In this case, it is set to 0.7 mm. The guide roller 1 and the dampening roller 3 are made of metal, the former having a diameter of 150 mm and the latter having a diameter of 100 mm.
φmm, the shaft and frame of the wiping roller 2 are made of metal, the outer peripheral surface is made of butyl rubber with a hardness of 50°, and the thickness is about 20 mm.The cleaning agent 4 is toluene, the doctor knife is a steel plate (about 1 mm thick), the weight is 2 kg, and the auxiliary roller. 8 is made of rubber, hardness is 50°,
The outer diameter was 8 mmφ, and the circumferential speed of all rollers was adjusted to the same 6 Qm/min via gear G, belt, etc.

As the paint for sand adhesion, a formulation was used in which the ratio of solid content such as alkyd resin, pigment, and extender to diluent was 1:1.

Furthermore, the gap between guide roller 1 and wiping roller 2 is 0.4 m.
It was set as m.

Further, in this embodiment, three such units were installed at 1 m intervals as shown in FIG.

Therefore, 8-square architectural panels having an uneven pattern surface coated with about 10 microns of the above paint using a spray gun were continuously supplied.

The wiping roller 2-1 wipes off only the uncured paint on the convex surface of this panel.

At this time, most of the paint film present on the convex surface is wiped off by the action of the elasticity of the rubber of the wiping roller and the frictional resistance.

The next-stage wiping roller 2-2.23 continuously performs such an operation in order to almost completely wipe off only the uncured paint present on the convex surface.

Further, the auxiliary roller 8 rotates while holding the guide roller 1, the insertion edges of the male and female parts, and the extension part, and conveys the product without slipping and while reinforcing the easily deformable end portions of the box-shaped cross section.

Further, the wiped paint and the like come into contact with the dampening roller 3 via the cleaning agent 4 while remaining attached to the wiping roller 2.

The adhering paint, so-called wiped off paint, and the like are dissolved by the cleaning agent 4 and transferred to the cleaning agent storage tank W via the dampening roller 3.As the roller rotates, the remaining amount of the cleaning agent 4 on the wiping roller 2 is removed. transported together with the

Then, when observing the decorative surface obtained by the device according to the present invention, it was found that the paint on the concave surface a was hardly wiped off, and only the paint on the convex surface was almost completely wiped off.

The decorative surface of the construction panel after sand was sprinkled on the decorative surface and excess sand was removed has a surface condition as shown in Figure 1.
There was no sand on the convex surface, and the decorative surface consisting of a mirror surface and an undulating surface made of sand enhanced the three-dimensional effect.

What has been described above is only one embodiment of the wiping device according to the present invention, and it is possible to install wind, a blowing mechanism, etc. between the wiping roll and the next wiping roll, or apply heat to the guide roller. You can also

Further, a metal fitting 9 may be provided to prevent the cleaning agent from leaking onto the decorative surface.

As mentioned above, according to the wiping device according to the present invention, the surface (
Continuously and reliably removes uncured paint, etc., with a very thin film thickness, which exists on the decorative surface, which has a randomly uneven patterned surface, and further removes the paint, etc., which exists on the convex surface. It has the feature of being wipeable.

Another feature is that uncured paint etc. on the convex surface of the uneven patterned surface which is not completely smooth or flat can be tracked and wiped off by elasticity and frictional resistance.
