Description

Adhesion impurity removal device on the surface of coater roll {AN APPARATUS FOR REMOVING THE ADHESION IMPURITY ON SURFACE OF COATER ROLL}

The present invention relates to a device for removing impurities deposited on the surface of the coater roll, and more particularly, it is easy to remove the fusion powder generated on the surface of the coater roll coating the organic solution on the surface of the steel sheet, dissolved impurities The present invention relates to an apparatus for removing fusion impurities on the surface of a coater roll capable of maintaining an optimal state of the coater roll so as to clean the roll surface and clean the surface of the roll to produce an organic steel sheet having excellent quality.

In order to improve the corrosion resistance in the areas where chemical conversion treatment and electrodeposition coating are difficult in the plated steel sheets generally used for home appliances and automobiles, a coater facility is applied to the surface of the steel sheet to apply organic resin coating.

FIG. 1 is a schematic view showing such a coater facility, as shown, a coater roll 3 external to the backing roll 6, a transfer roll 4 external to the outer circumferential surface of the coater roll 3, and the The pick-up roll 5 and the transfer roll 4 are formed by continuously forming a pickup roll 5 in which a part of the outer circumferential surface is immersed in the dream pan 8 filled with the organic resin solution. The solution transferred through the coater roll 3 was applied to the surface of the steel sheet wound around the backing roll 6.

However, fine organic matter adheres to the outer circumferential surface of the coater roll 3 during the organic coating operation, and an organic layer is fused to the surface of the coater roll 3 by mixing impurities into a solution filled in the drip pan 7. Impurity layer (hereinafter referred to as impurity) (F) is generated, and the operator cleans the coater roll 3 according to the coating state, and the outer circumferential surface of the coater roll 3 even after the organic coating operation is completed. Impurities (F) attached to the substrate must be removed, and when the impurity of the impurities (F) is removed, the surface coating work of the plated steel sheet causes a cause of greatly deteriorating the quality of the plated steel sheet product.

Accordingly, the conventional operation of removing the impurities F attached to the outer circumferential surface of the coater roll 3 stops the line in operation, and moves the drip pan 8 containing the solution back and forth to the cylinder 9. After the operation was completely withdrawn from the line, the operator sprayed the cleaning solution on the surface of the coater roll 3 located at the height and removed the impurity layer layer F having the organic layer attached to the roll surface as a cotton cloth.

However, such a conventional removal operation is difficult to completely remove the fusion organic layer (F) attached to the roll surface of the coater roll (3) is difficult to cause the coating defect during the operation of coating the organic solution on the steel sheet surface Due to the suspension of the equipment line in operation, workability is significantly reduced, and there is a problem that a danger occurs to the safety of an operator due to the handling of hazardous substances.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, the object of which is to safely and quickly remove the impurities attached to the surface of the coater roll during the coating operation, without interruption of the equipment line to improve the work productivity To provide an apparatus for removing fusion impurities on the surface of a coater roll, which can produce an organic coated steel sheet having a beautiful surface and excellent quality.

The operation of the present invention having the above configuration will be described.

In order to remove the fusion powder attached to the coater roll 3 using the apparatus 1 of the present invention, the upper and lower brackets 15a and 15b of the moving block 14 are installed in a vertically symmetrical structure. In the state where the rejection 50 is waiting on the side of the cotter roll 3, the external power is applied to the drive motor 31 fixedly installed on the base 19 to move the screw shaft 11 in the forward direction. When rotated, the movable block 14 having the upper and lower brackets 15a and 15b, which is screwed thereto and the upper and lower guide rods 12 and 13 are slidably assembled, is provided on the left side in the forward direction. Start to move horizontally to the right.

The horizontal movement of the moving block 14 is made and at the same time facing the outer peripheral surface of the coater roll (3), the injection pipe (51a), brush roll (52) (53) and absorbing, cotton cloth (54) (55) Only the lower side valve member of the valve member 51b assembled to the water supply line 51c is opened to the lower side removal part 50 arranged in order, and the upper side valve member keeps closing. Accordingly, the water for removal is supplied only to the injection pipe 51a disposed at the lower side of the removal unit 50, and the water sprayed through the injection nozzle 51 of the injection pipe 51a receives the coater roll 3. It is sprayed on the outer circumferential surface of).

At this time, the water supply line (51c) is connected to the main water supply line (51d) made of a flexible hose is easy to expand and contract according to the change in length, so that the water supply regardless of the movement of the moving block (14) You can do what you want.

Subsequently, at the same time as the water spray through the injection nozzle 51a, the contact roll 52b of the first brush roll 52 on the front side of the brush rolls 52 and 53 is rotated while the outer contact with the coater roll 3. The brush member 52c is in contact with the outer surface of the coater roll 3 to remove impurities while being driven to rotate.

At the same time, a second brush roll 53 having a driving gear 52e mounted on one end of the first shaft member 52d of the first brush roll 52 and a driven gear 53e geared at one end thereof is provided. The brush member 53c attached thereto while being rotated in the opposite direction to the first brush roll 53 is in contact with the outer circumferential surface of the coater roll 2 to remove impurities.

In addition, as the moving block 14 continues horizontal movement by the forward rotational driving force of the drive motor 31, water sprayed through the injection nozzle 51 is absorbed by the absorbent cloth 54, The outer surface of the water absorbed coater roll (3) is to be wiped clean by the cotton cloth (55).

On the other hand, when the horizontal movement of the movable block 14 is close to the rightmost end of the coater roll (3), the lower valve member 51b is closed to stop the water spray through the injection nozzle 51, When the removal unit 50 is positioned at the rightmost end of the coater roll 3, the power supply to the driving motor 31 is cut off to stop horizontal movement.

In this state, the removal unit 50 having the up-and-down symmetry structure is performed as the cylinder member 32 of the operation unit 30. When the cylinder member 32 fixed on the base 19 is moved forward, As the rack gear 34 mounted on the rod end is advanced, the pinion gear 33 geared with this is rotated in one direction and clockwise in the drawing, and the cylinder member is rotated 180 degrees until the pinion gear 33 is rotated 180 °. The forward operation of 32 continues.

At this time, the rotation of the pinion gear 33 of the cylinder member 32 when the upper and lower positions of the upper and lower brackets 15a and 15b assembled with the guide rods 12 and 13 attached thereto are completely switched. Forward operation is interrupted.

As described above, when the rotation of the removal unit 50 is completed, by applying an external power to the drive motor 31 that has been suspended, the moving block 14 is reversed in the reverse direction, to move from the right side to the left side in the figure. The screw shaft 11 is rotated in the reverse direction.

In this case, the moving block 14 is moved from the right side to the left side while supplying water to the spray nozzle 51 of the lower side removing unit 50 corresponding to the cotter roll 3 of the cotter roll 3. The operation of brushing impurities attached to the outer surface as brush rolls 52 and 53, absorbing water as the absorbent cloth 54, and cleaning the coater roll 3 cleanly as the cotton cloth 55 is the same as above. Will be repeated.

On the other hand, the operation to compress and remove the water absorbed in the absorbent, cotton cloth 54, 55 is to remove impurities at the rightmost end and the extreme end of the coater roll 3 before the rotation operation of the removal unit 50. The absorbent cloth 54 and the face cloth 55 of the irrelevant upper side removal part 50 are simultaneously made.

That is, when the upper and left ends of the cotter roll 3 of the moving block 14 are close to each other, absorption of the upper side removing part 50 that does not participate in the removal of impurities and assembly between the cotton cloths 54 and 55 is performed. The first, second, and third sliding bulkheads 57a, 57b, 57c, respectively, attached to the contact plate 58b of the third sliding bulkhead 57c and the guide rods 12, 13, respectively. The ends of the compression bar 58a start to contact each other.

Subsequently, when the horizontal movement of the movable block 14 is achieved, the distance between the contact plate 58b and the pressing bar 58a begins to narrow, thereby allowing sliding movement on the fixed sliding block 56a. The gap between the first and second sliding bulkheads 57a and 57b and the second and third sliding bulkheads 57b and 57c are narrowed, and the collection cloth 54 disposed therebetween is narrowed. ) And the cotton cloth 55 is compressed while reducing the first and second compression springs 54a and 55a embedded therein to have elastic restoring force.

Accordingly, the water absorbed by the collection cloth 54 and the cotton cloth 55 is squeezed and dropped to the bottom, and the dropped water is discharged and collected in the liquid box 58c, and collected in the liquid box 58c. Water is discharged downward through the discharge pipe 58d. At this time, the water collected through the collection box 59 fixed to the lower portion of the discharge pipe (58d) is discharged to the outside without contacting the coater roll (3).

In addition, the compression operation of the collection cloth, cotton cloth 54, 55 is stopped at the same time as the horizontal movement of the moving block 14 is stopped, and the compressed collection cloth 54 and cotton cloth to discharge the absorbed water ( 55 is a gap between the contact plate 58b and the pressing bar 58a when the moving block 14 is horizontally moved to a working position for removing impurities adhering to the surface of the coater roll 3. This is returned to its original state by the elastic restoring force of the first and second compression springs 54a and 55a which are freed away.

As described above, the transverse movement of the moving block 14 in the longitudinal direction of the coater roll 3, the collection, the compression of the cotton cloth 54, 55, the rotation of the moving block 14, the movement of the moving block 14 Rolling of the coater roll by removing the fusion impurities adhered to the surface of the coater roll 3 while reversing backward movement, collecting and compressing the cotton cloth 54 and 55, rotating the moving block 14, and moving forward. You can always keep clean.

According to the present invention as described above, by moving the drive shaft in the forward and reverse direction of the screw shaft, the moving block reciprocates in the longitudinal direction of the coater roll while spraying the cleaning water from the injection nozzle, a pair of brush rolls Are rotated in opposite directions to remove impurities fused to the surface of the coater roll, absorb water for washing as absorbent cloth and cotton cloth, and remove absorbed impurities and compress water absorbed cotton cloth to remove them. By discharging, the surface state of the coater roll can be kept clean at all times. Therefore, it is possible to prevent the occurrence of bonding of the steel sheet due to poor coating and to produce an organic resin coated steel sheet having a beautiful surface and excellent quality.

In addition, it is possible to remove impurities during the operation of the coater roll without stopping the line, thereby significantly improving the productivity of the work, and the effect of preventing the worker's safety accidents caused by harmful substances is obtained.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
