Abstract

(57) [Summary] [Purpose] You can easily obtain the coating width and thickness as desired.
The coating liquid 3 is applied without scattering. A transfer roller 4 is placed on an object to be coated 2, the transfer roller 4 is relatively rolled along the object to be coated 2, and a coating liquid 3 is supplied from a coating liquid supply member 5 to the transfer roller 4. The coating liquid 3 is transferred from the transfer roller 4 to the object 2 to be coated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coating device for coating a coating liquid such as a paint or an adhesive onto an object to be coated. The coating device of the present invention is used for partial coating of adhesive or coating material, surface pattern coating, and the like.

[0002]

[Prior Art]

 Conventionally, when a coating liquid such as paint or adhesive is applied to the end surface in the axial direction of an annular object to be coated over the entire circumference, conventionally, a metering discharge nozzle a as shown in FIG. 2 or a spray nozzle b as shown in FIG. Is used. The object to be coated c is supported by the work holder d and is adapted to rotate in the circumferential direction at a predetermined speed.

[0003]

[Problems to be solved by the device]

 The conventional technology has the following problems. In the case of the constant-quantity discharge nozzle a of FIG. 2, it is difficult to select a nozzle a of a size and shape that matches the viscosity of the coating liquid e in order to obtain the desired coating width and thickness, and the coating speed Is difficult to adjust and manage. In the case of the spray nozzle b shown in FIG. 3, masking is necessary because partial coating cannot be performed, which is troublesome. In addition, since the coating area is widened, the yield of the coating liquid e is not good, and the coating liquid e is widely scattered around the object c to be contaminated, which is troublesome to clean and manage. Difficult to connect with processes and automate.

[0004]

[Means for Solving the Problems]

 In view of the above points, the present invention has been devised to solve the problems found in the above-mentioned conventional techniques, and in order to achieve this object, a relative position is provided on the article to be coated along with the article to be coated. (EN) Provided is a coating device including a transfer roller which rolls in a horizontal direction and a coating liquid supply member which supplies a coating liquid to the transfer roller.

[0005]

[Action]

 Place the transfer roller on the object to be coated, rotate the transfer roller relative to the object to be coated, supply the coating liquid from the coating liquid supply member to the transfer roller, and apply the coating liquid from the transfer roller to the object to be coated. Transfer to.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a work holder 1 supports an annular article 2 to be rotated in a circumferential direction at a predetermined speed. The coating device, which coats the coating liquid 3 around the circumference, is placed on the article 2 to be coated, and a transfer roller 4 that rolls at a fixed position along the article 2 to be coated, and the transfer roller 4 A coating liquid supply member 5 for supplying the coating liquid 3 to the coating liquid supply member 5. The coating liquid supply member 5 includes a tank 6, a nozzle 7, a fixed amount supply device 8, a roller support 9, and the tank 6. A cylinder 10 that moves up and down together with the transfer roller 4.

The size (particularly the width) and the shape (particularly the cross-sectional shape of the transfer groove) of the transfer roller 4 are determined according to the size and shape of the object 2 to be coated, the coating width, etc. When the work piece 1 is placed on the article to be coated 2, the work holder 1 is rotated to relatively move the transfer roller 4 along the article 2, and the application liquid 3 from the application liquid supply member 5 to the transfer roller 4 is kept constant. It is quantitatively supplied and the coating liquid 3 is transferred from the transfer roller 4 to the object to be coated 2. The thickness is arbitrarily determined depending on the feeding speed of the object to be coated 2 and the supply amount of the coating liquid 3.

According to the coating apparatus described above, the following effects can be obtained due to its configuration and operation. That is, the coating width can be freely changed depending on the size of the transfer roller 4, and the thickness can be arbitrarily determined by the feeding speed of the object to be coated 2 and the supply amount of the coating liquid 3. Further, since the coating liquid 3 does not scatter, masking is not required, the yield of the coating liquid 3 is improved, and the environment of the device can be improved by eliminating the contamination of the device. Connection with processes and automation can be facilitated. The object to be coated 2 is not limited to the endless one.

[0010]

[Effect of the device]

 The present invention has the following effects. That is, the coating width can be changed automatically depending on the size of the transfer roller, and the thickness can be arbitrarily determined by the feeding speed of the object to be coated and the supply amount of the coating liquid. In addition, since the coating solution does not scatter, masking is not required, the retention rate of the coating solution is improved, and the environment can be improved by eliminating the stains on the equipment. Connection and automation become easier. INDUSTRIAL APPLICABILITY The coating device of the present invention can be used for partial coating of metal fitting adhesive coating of a molded product and surface pattern formation.
