At this time, the coating liquid supply unit 110 is a roller in the lateral direction formed of a material such as a metal material.

The coating liquid reservoir 120 is disposed below the coating liquid supply unit 110 and the first coating liquid transfer unit 140 to be described later and is supplied with the coating liquid on the outer peripheral surface of the coating liquid supply unit 110 when the coating liquid supply unit 110 rotates.

The coating liquid reservoir 120 is connected to the first coating liquid transfer unit 140 to allow the coating liquid to be dropped and collected when the coating liquid is transferred to the first coating liquid transfer unit 140 through the coating liquid supply unit 110. [ As shown in FIG.

The coating liquid thickness regulating member 130 is disposed on the outer circumferential surface of the coating liquid supply unit 110 to adjust the coating thickness of the coating liquid applied to the outer circumferential surface of the coating liquid supply unit 110, And a lifting driver 134.

The coating thickness adjusting unit 132 adjusts the thickness of the coating liquid applied to the coating liquid P on the outer circumferential surface of the coating liquid supplying unit 110 by raising and lowering the coating liquid to a thickness corresponding to the thickness of the coating layer C formed on the coating target P, It applies to this.

The lifting and lowering driving unit 134 lifts the coating thickness adjusting unit 132 to a height corresponding to the thickness of the coating liquid coating, and for example, a cylinder or the like is applied thereto.

The first coating liquid transferring part 140 is disposed in a state in which a part of the outer circumferential surface is in close contact with the front of the coating liquid supplying part 110 and when the coating liquid applied to the coating liquid supplying part 110 is buried in the outer peripheral surface in a clockwise rotation To the second coating liquid transfer unit 150, which will be described later.

On the other hand, the first coating liquid transfer unit 140 is a roller in a transverse direction formed by a rubber material or the like and is manufactured to have a hardness of 80 °.

In this case, the first coating liquid transfer unit 140 is preferably disposed so as not to touch the surface of the coating liquid stored in the coating liquid reservoir 120 so that the coating liquid is delivered only by contact with the coating liquid supply unit 110.

In addition, a plurality of the coating liquid supply unit 110 and the first coating liquid transfer unit 140 may be arranged so that at least one of the coating liquid supply unit 110 and the first coating liquid transfer unit 140 are sequentially arranged to correspond to the length of the coating target P, respectively.

The second coating liquid transfer unit 150 is disposed in a state in which a part of the outer circumferential surface of the second coating liquid transfer unit 140 is in close contact with the inclined front side of the first coating liquid transfer unit 140 so that the first coating liquid transfer unit 140 is rotated clockwise The coating liquid is applied to the outer circumferential surface of the coating material P so as to form a coating layer on the coating surface of the coating material P.

At this time, the second coating liquid transfer unit 150 is a roller in the transverse direction formed of a metal material or the like.

The second coating liquid transfer unit 150 functions to raise the coating liquid on the coating surface of the coating target P when the coating target P is supplied by the coating target supply unit 160.

Here, the coating object P refers to a paper, a photograph, a roll paper, and the like, and is cut or supplied or continuously supplied, but is not limited thereto and is applicable to various kinds of objects.

The coating object supply unit 160 is spaced apart from the second coating liquid transfer unit 150 by a thickness of the coating object P and is spaced apart from the second coating liquid transfer unit 150 by a thickness of the coating object P, (See FIG. 3) so that the coated surface of the coating object P is coated.

In this case, it is preferable that the coating object supply unit 160 and the second coating liquid transfer unit 150 are disposed on the same vertical line, and the coating point on the bottom surface of the coating target P and the top surface thereof The coating operation can be performed.

On the other hand, the coated object supply unit 160 is a transverse roller formed of a rubber material or the like and is manufactured to have a hardness of 60 to 70 degrees.

Here, the coated object supply unit 160 is manufactured to have a lower hardness than the first coating liquid transfer unit 140 made of the same rubber material. This is because the object to be coated in the coating object supply unit 160 is a coating object P such as paper, photograph, roll paper or the like, unlike the coating liquid in the first coating liquid transfer unit 140, P is smoothly supplied without slip.

The coating object supply unit 160 includes a rotation unit 162 for rotating and a lift unit 164 for moving the rotation unit 162 to adjust the gap between the second coating liquid transfer unit 150 and the second coating liquid transfer unit 150. (See Fig. 4)

That is, the coating object supply unit 160 can be implemented through the lifting unit 164 in which the height adjustment according to the thickness of the coating target P is controlled by the control unit.

The coating object supply unit 160 may be provided with radial projections and depressions along the outer circumferential surface thereof to prevent slipping of the coating object P during the supply thereof. (See Fig. 5)

The drying unit 170 is disposed in front of the second coating liquid transfer unit 150 and functions to apply heat or hot air to the coating layer C applied to the surface of the coating target P to dry the coating layer.

The control unit includes a first driving unit for rotating and driving the coating liquid supply unit 110, a lifting and driving unit 134 of the coating liquid thickness adjusting member 130, a second driving unit for rotating and driving the first coating liquid delivering unit 140, A second driving unit for rotating the coating liquid transfer unit 150 and a rotation unit 162 for rotating the coating object supply unit 160 and controls the operation of the first to third driving units and the rotation unit 162 So as to be rotated in the clockwise direction (reference in FIG. 3).

The reason why the coating liquid supply unit 110, the first coating liquid transfer unit 140 and the second coating liquid transfer unit 150 are rotated upward (clockwise - reference to FIG. 3) is that the rotation of the coating liquid supply unit 110 Since the coating liquid of the coating liquid reservoir 120 is buried in the first coating liquid transfer unit 150, the coating liquid is delivered only through the upper end of the outer peripheral surface of the first coating liquid transfer unit 140 and the second coating liquid transfer unit 150, to be.

If the direction of rotation of the second coating liquid transfer unit 150 and the coating target supply unit 160 are different from each other, the coating material P is drawn well when the coating material P is drawn in. However, Since the coating is not uniform, there is a problem that the coating must be performed several times.

As a result, when the rotation directions of the second coating liquid transfer unit 150 and the coating object supply unit 160, which are the introduction units, are the same in the direction of travel of the coating material, coating can not proceed. The coating material can be coated smoothly by the difference in the material of the coating material supply part 160 formed by the transfer part 150 and the rubber material and the hardness of the coating material supply part 160, There is an advantage such as being.

Therefore, the operation of the coating apparatus 100 according to the present invention is as follows.

First, when the coating liquid is stored in the coating liquid reservoir 120 and the lower portion of the outer peripheral surface of the coating liquid is immersed in the coating liquid, the coating liquid is supplied to the outer circumferential surface of the coating liquid supply unit 110, .

At this time, the coating thickness control unit 132 is positioned on the coating liquid supply unit 110 by the elevation driving unit 134 so that the thickness of the coating liquid transferred to the first coating liquid transfer unit 140 becomes .

Next, when the first coating liquid transfer unit 140 is rotated upward, the coating liquid is transferred to the second coating liquid transfer unit 150 at a point of contact with the coating liquid supply unit 110.

The coating object P supplied between the second coating liquid transfer unit 150 and the coating object supply unit 160 is supplied to the second coating liquid transfer unit 150 while being supplied by the rotation of the coating object supply unit 160, The coating liquid is supplied to the surface of the coating layer (C).

Next, the coated coating layer C of the coating target P is dried by the drying unit 170 in the discharging process of the coating target P.
