Problems solved by technology

This method brings many problems: it requires many man-hours, many labor costs and many working hours and it enlarges the coating booth
When this roller coating device is applied to coat a coated object whose coating surface is a curved surface, it is difficult to apply the roller brush uniformly on the curved surface
Therefore, it is considered more difficult to automate this coating process

[0295] First, an embodiment of the first invention will be described below.

[0296] figure 1 It is a perspective view generally showing a coating apparatus including a pressure supply roller for coating as a first embodiment of the present invention. exist figure 1 Among them, the pressure supply roller for coating according to the first embodiment of the present invention is a part of the roller brush assembly 10 .

[0297] First, the pressure supply roller for coating according to the first embodiment of the present invention will be described below.

[0298] figure 2 is a longitudinal sectional view showing the roller brush assembly viewed in the axial direction. image 3 for along figure 2 A cross-sectional view taken along line A-A in .

[0299] Such as figure 2 with 3 The roller brush assembly 10 shown includes a solid cylindrical body 11 and a roller brush 12 attached to the outer circumference of the solid cylindrical body 11 in an assembled manner.

[0311] Next, a second embodiment of the present invention will be described.

[0312] The second embodiment concerns the way of feeding the paint to the axial center hole 13 of the solid cylindrical body 11 comprising a pressure feed roller for coating and the way of supporting the solid cylindrical body 11 .

[0313] as combined Figure 29 As mentioned, in a conventional roller coating device, the paint is delivered to the roller from one end of the roller, and the roller is supported in the manner of a cantilever beam. Therefore, the conventional roll coater has the disadvantages as described above. In the current embodiment, the paint pressure supply tube 24 (see figure 1 ) is connected to both ends of the axial center hole 13 of the solid cylindrical body 11. The coating pressure supply roller is rotatably supported at both ends by arms 31 , and these arms 31 are connected together by a lower frame 32 , thereby forming a support 30 .

[0318] Next, a third embodiment of the present invention will be described.

[0319] Such as figure 1 As shown, the coating device of the third embodiment includes a rotatable support mechanism 40 for rotating the support member 30 supporting the roller brush assembly 10 in the direction of arrow A, and for making the roller brush assembly rotate along the arrow A The vertically movable support mechanism 50 that moves vertically in the direction of B.

[0320] This support 30 comprises two arms 31 and a lower frame 32 bridging between those arms. The two arms 31 rotatably support the roller brush assembly 10 between them. The support 30 is mounted on a rotatable support mechanism 40 , and the rotatable support mechanism 40 is mounted on a vertically movable support mechanism 50 .

[0321] The rotatable support mechanism 40 is constructed such that the plate 41 extends on the upper surface of the lower frame 32 parallel to the axis of the roller brush assembly 10 . The pla...

Abstract

An object of the present invention is to provide a coating device of the roller type which reduces a waste of coatingmaterial and distributes the coating material uniformly to the roller brush. The coating device includes a solid cylindrical body (11) being solid except an axial center hole (13), and radial holes (14) radially extended from a plurality of positions of the axial center hole (11), a roller brush (12) applied to the outer periphery of the solid cylindrical body (11), coating-material press feeding pipes (24) connected to both ends of the axial center hole (13) of the solid cylindrical body (11), and an arm part (31) for supporting the solid cylindrical body (11) at both ends of the solid cylindrical body (11). Those components are entirely supported by a turnable support mechanism (40) and a vertically movable support mechanism (50).

Description

technical field [0001] The present invention relates to a pressure feed roll for coating, a roll coater, a curved surface operable roll coater, and an automatic coater using those, and a coater method. More specifically, the present invention relates to a roller coating which is very suitable for delivering paint or the like to a roller brush by means of a pump or the like. Background technique [0002] Roll coaters have been used in various fields. Such roll coaters are used, for example, in automobile manufacturing plants. In this factory, a roll coater is used to form a protective film on the painted film surface of an automobile in order to protect the painted film from rainwater, iron powder, pollen, bird droppings, etc. and thus prevent deterioration of the coating quality. [0003] In known roller coating devices, the roller is manually turned in a paint container filled with paint and the paint is allowed to penetrate into the roller. This method makes it difficul...
