Description

[Detailed description of the invention] The present invention relates to a coating device for applying a coating material such as an adhesive or a paint onto a substrate to be coated using a rubber roll. A coating material 3 such as adhesive or paint is supplied and stored in the upper part between the rubber rolls 1 and the second metal roll 4 arranged below the rubber roll 1 in parallel with the rubber roll 1. In a coating device that applies a coating material 3 to a substrate 10 through a substrate 10, a gate 6 that can be opened and closed is provided on a liquid flow prevention plate 5 disposed on both sides of a rubber roll 1 and a first metal roll 2. - Connect the artificial side of container 80 to the outside of container 8 and
This relates to a coating device in which a filter 9 is disposed on the outlet side of the coating device.

In a general coating device, as shown in FIG. 1, a coating material 3 such as an adhesive or paint is supplied and stored in the upper part between a rubber roll 1 and a first metal roll 2, and a substrate 10 to be coated is coated. When being fed over the second metal roll 4, the coating material 3 adhering to the rubber roll 1 is transferred onto the substrate 10 to be coated.

Here, 11 is the motor, 12, 13.14 is the Cheno, and 15
is a pressure adjustment spring.

When the coating material 3 is applied to the substrate 10 to be coated, foreign matter adhering to the surface of the substrate 10 to be coated adheres to the rubber roll 1,
There is a strong tendency for foreign matter to be mixed into the coating material 3 stored between the rubber roll 1 and the first metal roll 2, and the amount thereof to be increased.

In this case, depending on the size of the foreign matter, the size of the gap between the first metal roll 2 and the rubber roll 1, the accumulation of foreign matter, the flow condition of the coated material (viscosity, etc.), the product may be coated again with the coated material 3. It adheres irregularly to the surface of the coating base material 10.

Conventionally, in the case of this foreign matter removal, the apparatus is stopped once, the applied material 3 such as adhesive that has accumulated on the upper part between the rubber roll 1 and the first metal roll 2 is removed, and each roll 1° 2.4 is cleaned. The distance between the rolls 1 and 2 may be adjusted, and a new coating material 3 such as adhesive may be put into operation.In addition, if the coating material 3 is a solvent type such as paint and has a low viscosity, there is no fluid flow prevention plate 5. , collect the paint etc. vIJ3 that flows down from this part,
There are examples of reuse.

However, the viscosity of application 3 of adhesive etc. is high (approximately 13,000~
35,000 cps) has a relatively short usable life (20
~40 minutes), the latter method of the conventional example cannot be used.

In other words, the coating material 3 such as an adhesive is hardened relatively quickly (in about one hour) in the route for recovering the coating material 3, making it impossible to circulate the coating material 3 in the route.

Therefore, generally only the equipment shown in Figure 1 is used.
If foreign matter enters the coating i#3 in the -L section between the rubber roll 1 and the first metal roll 2, leave the foreign matter coated on the coated substrate 10 together with the coated material 3. mosquito,
Further, the only method available is to temporarily stop the apparatus, discard the coated material 3 contaminated with foreign matter, and supply a new coated material 3, as in the former method.

The present invention has been developed in view of the above points, and the purpose of the present invention is to open the gate, put the coating material into the container, and remove foreign matter with the filter, without stopping the device. It is an object of the present invention to provide a coating device that can apply a coating material to a substrate to be coated, and can prevent foreign matter from adhering to the substrate to be coated.

The present invention will be explained in detail below with reference to Examples.

The applied material 3 such as adhesive or paint on the upper part between the rubber roll 1 and the first metal roll 2 is agitated by the rotation of each roll 1, 2.

Foreign matter tends to move in the direction from A to mouth depending on the agitation situation of the applied material 3.

Taking advantage of this phenomenon, a gate 6 is provided on the liquid flow prevention plate 5, and this gate 6 is closed by an opening/closing plate 7 that can be opened and closed.

A container 8 is removably connected to the outside of this gate 6 in a cassette type, and a filter 9 is provided on the opposite side of the container 8 from the gate 6.
It is designed to fall in the direction of.

However, when foreign matter gets mixed into the applied material 3 such as adhesive or paint on the upper part between the rubber roll 1 and the first metal roll 2, and the amount thereof becomes relatively large, the opening/closing plate 7 is opened and the gate 6 is opened properly. When the container is opened for a period of time (approximately 3 to 6 minutes), the applied material 3 flows into the container 8 through the gate 6.

At this time, as the rubber roll 1 and the first metal roll 2 are operated, the foreign matter in the applied material 3 moves from i to mouth and enters the container 8.

After an appropriate period of time, close the gate 6, remove the container 8, and add the applied material 3.
is immediately returned to the upper part between the rubber roll 1 and the first metal roll 2.

The foreign matter on the filter 9 is discarded, and the container 8 is cleaned and used again.

As described above, in this invention, a gate that can be opened and closed is provided on the liquid flow prevention plate, and the inlet side of the container is connected to the outside of the gate, and a filter is placed on the outlet side of the container, so that by opening the gate, The coating material can be poured into a container and foreign matter can be removed by a filter, and the foreign matter can be prevented from adhering to the substrate to be coated, and the foreign matter can be removed without stopping the apparatus.
