Description

Technical Field [0001] The present invention relates to a drip pan maintenance apparatus and a maintenance method for a drip pan,

The present invention relates to a drip pan maintenance apparatus and a drip pan maintenance method. More particularly, the present invention relates to a drip pan maintenance apparatus capable of improving the cleanliness of a drip pan by replacing or cleaning a drip pan even on-line, and a method of maintaining the drip pan using the maintenance apparatus.

Generally, a black resin steel sheet refers to a steel sheet excellent in lubricity and workability coated with a black resin on a strip in a coater.

1, the black resin solution contained in the drip pan 2 is poured in the pick-up roll 3 and then transferred to the applicator roll 5 through the transfer roll 4 And the applicator roll 5 forms a gap with the backing roll 6 to apply the black resin solution deposited on the applicator roll 5 to the strip as it passes through the gap.

When the strip 1 is coated with the black resin solution, the black resin solution flowing from the pickup roll 3, the transfer roll 4, or the applicator roll 5 is collected and reused.

For this purpose, a drip pan 2 is provided below the pickup roll 3, the transfer roll 4 and the applicator roll 5, and a black resin solution flowing down from the surface of each roll or strip is supplied to the drip pan 2, Respectively.

Such a conventional drip pan has a form of a box opened on its top surface, and a black resin solution is contained therein. As the part of the pickup roll 3 is immersed in the resin solution, the resin solution is deposited on the surface of the pickup roll 3 in accordance with the rotation of the pickup roll 3 and sequentially transferred to the transfer roll 4 and the applicator roll 5 ).

At this time, a solution supply pipe 7 for supplying a black resin solution may be provided on the upper side of the drip pan 2.

An invention related to such a drip pan is Korean Patent Laid-Open Publication No. 2013-0071855 (2013.07.01) of the present applicant entitled " Drip pan for preventing black resin solution from solidifying ".

However, since the drip pan 2 is fixed integrally with the pickup roll 3, there is a problem that replacement of the drip pan 2 is difficult.

In addition, even when the on-line (on-line (product movement and product production)) operation is performed, the drip pan can not be automatically changed when the post-treatment solution is changed, and the drip pan 2 is difficult to be cleaned cleaning).

Further, since the replacement and cleaning of the drip pan 2 are difficult, there is a problem that the cleanliness of the post-treatment solution deteriorates.

The drip pan maintenance apparatus 1 is an example of cleaning the drip pan 2 by moving the drip pan 2. The drip pan maintenance apparatus 1 is not limited to this example, 12) It goes without saying that the cleanliness can be maintained by washing and drying.

The control unit 600 may control the door 120 to open the door 120 when the drip pan 2 moves along the horizontal linear guide 310.

Hereinafter, a drip pan maintenance method (S1) according to an embodiment of the present invention will be described with reference to FIGS. 8 and 9. FIG.

The drip pan maintenance method (S1) maintains the drip pan (2) by using the drip pan maintenance apparatus (1). In describing the drip pan maintenance method (S1) The components of the drip pan maintenance apparatus 1 are denoted by the same reference numerals, and a description of each component of the drip pan maintenance apparatus 1 will be omitted.

The drip pan maintenance method (S1) includes moving a drip pan from the post-processing position to the cleaning position (S10), spraying a cleaning agent to the drip pan moved to the cleaning position (S20); Spraying a rinsing solution onto the drip pan (S30); And drying the drip pan (S40).

9 (a) and 9 (b), in step S10 of moving the drip pan from the post-processing position to the cleaning position, the resin solution 20 contained in the drip pan 2 The drip pan 2 is moved to a cleaning position for cleaning the drip pan S at a post-processing position where the strip is post-processed.

The drip pan 2 positioned at the post-processing position can be moved to the cleaning position along the linear guide 300 by the moving part 400.

At this time, the replacement drip pan 2a waiting at the replacement position can be moved along the linear guide 300 to the post-processing position for smooth line operation of the post-processing process.

That is, when the drip pan 2 located at the post-processing position is moved to the cleaning position, the replacement drip pan 2a, which is waiting at the replacement position for making the drip pan replaceable, moves along the linear guide 300 And moved to the post-processing position.

Then, the resin solution 20 is accommodated in the replacement drip pan 2a moved to the post-processing position, so that the replacement drip pan 2a can perform a post-treatment process of coating the strip.

In the step S20 of spraying the cleaning agent to the drip pan moved to the cleaning position and the step S30 of spraying the rinse solution to the drip pan, as shown in FIG. 9C, The cleaning liquid and the rinse solution can be sequentially sprayed onto the drip pan 2 through the nozzle 510 of the drip pan. Accordingly, the surface of the drip pan 2 can be cleaned.

In step S40 of drying the drip pan, dry air is sprayed to the drip pan 2 using the air blower 520 to dry the drip pan 2 as shown in Fig. 9 (c) .

Then, the dried drip pan 2 moves to the replacement position and can perform the role of the replacement drip pan 2a.

The drip pan maintenance apparatus 1 moves the drip pan 2 used in the coater apparatus 10 to clean and dry the drip pan 2 and moves the replacement drip pan 2a to the coater apparatus 10, Can be smoothly performed.

Further, the drip pan maintenance apparatus 1 cleans and dries the contaminated drip pan 2 to maintain it in a clean state. That is, the surface cleanliness of the drip pan 2, which is contaminated due to the contamination of the resin solution 20, is maintained.

Since the drip pan maintenance apparatus 1 removes the resin solution 20 remaining in the drip pan 2 when the resin solution 20 is replaced with the resin solution 20 remaining in the drip pan 2, It is possible to prevent contamination of the other resin solution supplied by the resin.
