However, other shapes such as a corrugated shape and a diagonal line shape may be used, and these may be combined as appropriate. Moreover, even if it is a pattern and characters, such as a character, the rotary screen 21 should just be opened as it is.
The base material 2 is introduced from the vicinity of the free roller 33c from the direction of the arrow A, and is laminated on the belt 11 of the pattern coating apparatus 1. The belt 2 and the base material 2 in a laminated state move around the pattern coating apparatus 1 according to the roller group that rotates in the arrow B direction.
The coating material supply unit 4 is a nozzle that ejects the coating material, and is disposed inside the cylindrical rotary screen 21. The coating material supply unit 4 may be a brush or the like as long as it supplies a coating material, and is not limited to a nozzle. The coating material 3 is supplied to the base material 2 from the coating material supply unit 4 through the opening 22 of the rotary screen 21 at a position adjacent to the first pressing roller 35a.
As shown in FIG. 3, in the belt 11, the coating portion is recessed to form the recesses 12 and 12, and the recesses 12 and 12 are not formed in the uncoated portion. The recesses 12 and 12 are recessed by a predetermined depth, and the depth may be changed according to the viscosity of the coating material 3. The shape of the recesses 12 and 12 is formed according to the pattern coating. When pattern coating other than the present embodiment is performed, the recesses 12 and 12 corresponding to the pattern may be formed. When the coating material 3 is applied to the substrate 2 by the recesses 12 and 12, the applied material enters the recesses 12 and 12 on the belt 11 side and accumulates.
As shown in FIG. 1, the belt 11 may be stretched over a rotary screen 21, and the removal unit 6 may be disposed at a portion away from the rotary screen 21. The removal part 6 is a member with a protruding tip, and the belt 11 and the base material 2 are laminated, and the coating material 3 is applied thereon (see FIG. 4C), and an uncoated part. The coating liquid 3 adhered to the coating material or the coating material 3 applied to the coating part more than necessary can be peeled off.
The coating material 3 is supplied to the base material 2 through the opening 22 from the coating material supply unit 4 disposed inside the rotary screen 21, and the part to which the coating material 3 is supplied to the base material 2 In addition, it is necessary to control the movement of the belt 11 so as to correspond to the rotation of the rotary screen 21 so that the concave portions 12 and 12 of the belt 11 are positioned.
The movement control of the belt 11 is performed by the control ports 14 and 14 of the belt 11 and the convex portions 36 and 36 formed on the driving roller 32. As shown in FIG. 3, the control ports 14 are continuously opened on both sides in the width direction of the belt 11 from the front surface to the back surface. Convex portions 36 and 36 (see FIG. 1) are formed on the contact surface of the driving roller 32 with the belt 11, and the convex portions 36 and 36 engage with the control ports 14 and 14. Thereby, the movement of the belt 11 due to the rotation of the driving roller 32 can be adjusted, and the rotation speed of the rotary screen 21, the position of the opening 22, and the recesses 12, 12 of the belt 11 can be controlled to coincide. Become.
Next, the pattern coating method to the base material 2 is demonstrated.
As shown in FIG. 1, the base material 2 introduced from the direction of the arrow A is laminated with the belt 11. And if it conveys between the 1st press roller 35a and the rotary screen 21, the coating material 3 will be supplied from the coating material supply part 4 through the opening part 22 of the rotary screen 21 (explained above).
As shown in FIG. 4 (a), the belt 11 has recesses 12 and 12 formed at the supply position of the coating material 3, and the base material 2 is introduced and laminated as shown in FIG. 4 (b). It becomes. Then, as shown in FIG. 4C, the coating material 3 is supplied to the surface of the base material 2 from the laminated state of the belt 11 and the base material 2. In this state, the base material 2 to which the coating material 3 has been supplied by the pressing of the first pressing roller 35 a and the rotary screen 21 enters the belt 11 side corresponding to the recesses 12 and 12 of the belt 11.
The base material 2 supplied with the coating material 3 is conveyed to the rotary screen 21 and the drive roller 32. As shown in FIG. 1, the second base material 5 is introduced from the direction of the arrow C in the vicinity of the second pressing roller 35 b adjacent to the driving roller 32 pressed against each other, and further laminated. FIG. 4D shows a state where the three layers are stacked. It is pressed by the driving roller 32 and the second pressing roller 35b from the three-layered state, and the final pattern-coated substrate 2 can be carried out in the direction of arrow D in FIG.
