On the other hand, the number of the driven shafts 25 can be increased or decreased in correspondence with the drive shaft 35 and the conveying member 30, which will be described later.

A driven ring 26 is provided at the upper end of the driven shafts 25 and a driven ring 26 is disposed inside the intermediate housing 13. Each of the driven rings 26 is inserted into an intermediate through hole 13a formed in the intermediate housing 13 and the driven ring 26 has an outer diameter larger than the intermediate through hole 13a, Can be prevented from being detached from the inside of the intermediate housing 13. [ The intermediate elastic member 27 is also installed on the driven shafts 25 and is disposed between the driven ring 26 and the bottom surface of the intermediate housing 13. [ The intermediate limiter ring 28 is fixedly mounted on the follower shafts 25 and can be disposed outside the intermediate housing 13 to limit the maximum rising height of the follower shafts 25.

The drive shafts 35 are provided in a number corresponding to the respective slave shafts 25 and are disposed on the straight line with the respective slave shafts 25 opposed to each other. The upper end of each driving shaft 35 is inserted into an upper through hole 10a formed in the upper housing 10. A lower end of each driving shaft 35 is in contact with each of the driven rings 26 opposed to each other, (39). The drive ring 39 is disposed inside the intermediate housing 13 and has an outer diameter larger than that of the upper through hole 10a to prevent the drive shaft 35 from being detached from the inside of the intermediate housing 13. [

Further, the conveying member 30 is disposed inside the upper housing 10. [ Each of the conveying members 30 is disposed between a plurality of protrusions 34 and protrusions 34 which are radially extended with respect to a predetermined center of rotation and are spaced from each other and are spaced from the apexes of the protrusions 34 And has depressed portions (32) formed therein. The depressed portion 32 and the protruding portion 34 of the transfer member 30 are alternately formed and the depressed portion 32 and the protruded portion 34 may be formed in plural corresponding to each other. Further, each of the conveying members 30 may have the same shape.

The conveying members 30 are provided in plural so as to correspond to the drive shaft 35. For example, the conveying members 30 are provided with the front and rear conveying members 30a and 30c and the front and rear conveying members 30a and 30b, And a central transferring member 30b disposed between the transferring members 30a and 30c. Each of the conveying members 30 is rotatable together with the respective forward, middle and rear conveying shafts 31a, 31b and 31c corresponding to each other and each of the conveying shafts 31 is rotatable together with the upper housing 10 And can be rotatably connected.

As described above, the drive shafts 35 are respectively located below the respective conveying members 30. A roll bracket 37 is connected to the upper end of each drive shaft 35, and the pushing roll 38 can be rotatably connected to the roll bracket 37. An upper elastic member 36 is provided between each of the roll brackets 37 and the bottom surface of the upper housing 10 and the upper elastic member 36 can provide an elastic force toward the transfer member 30. [ . For example, the upper elastic member 36, the intermediate elastic member 27, and the lower elastic member 19 may be coil springs.

That is, each of the pushing rolls 38 can move along the depressed portion 32 and the protruding portion 34 of the conveying member 30 by the rotation of the conveying member 30. For example, when the front pushing roll 38a is positioned on the projecting portion 34a of the front transfer member 30a, the forward drive shaft 35a descends and the forward slave shaft 25a descends, The lower housing 17 is inclined toward the front pushing shaft 60a as the lower housing 25 is lowered. Therefore, the front pushing shaft 60a is lowered so that the cleaning member 20 can press the plating roll 8 in a tilted forward direction.

The driving roll 70 is located at one side of the cleaning member 20 and can be disposed behind the cleaning member 20 around the rotation direction of the plating roll 8, for example. The driving roll 70 can abut against the plating roll 8 and rotate in the direction opposite to the plating roll 8 and the lower ends of the cleaning member 20 and the driving roll 70 can rotate in the direction opposite to the center of the plating roll 8 Are located at the same radius as the reference.

The rotation shaft 75 is axially coupled to the driving roll 70 and is rotatable together with the driving roll 70. A power transmission shaft 71 is disposed above the rotation shaft 75. [ The bearing block 76 supports both sides of the rotary shaft 75 so that the rotary shaft 75 can rotate. The power transmitting shaft 71 may be disposed inside the upper housing 10 and may be disposed behind the conveying shaft 31c of the rear conveying member 30c. The lower end of the fixed shaft 72 is connected to the bearing block 76 and inserted into the upper rear through hole 10b formed in the bottom surface of the upper housing 10 at the upper end of the fixed shaft 72, .

The lower support ring 74 is fixedly mounted on the fixed shaft 72 and is located below the bottom surface of the upper housing 10. The driving elastic member 77 may be installed between the lower supporting ring 74 and the bottom surface of the upper housing 10 to provide an elastic force toward the driving roll 70. Therefore, the driving roll 70 is rotatable together with the plating roll 8 in close contact with each other, and the impact applied to the plating roll 8 through the buffering force of the driving elastic member 77 can be minimized.

The first drive belt 92 may be connected to a pulley (not shown) fixed to the rotation shaft 75 and the power transmission shaft 71 and the power transmission shaft 71 may rotate together with the drive roll 70 And can be rotated by the rotation shaft 75. The power transmission shaft 71 and the rear conveying shaft 31c and the rear conveying shaft 31c and the central conveying shaft 31b and the central conveying shaft 31b and the front conveying shaft 31a are connected to each other at positions corresponding to each other. And are connected to the second to fourth drive belts 93, 94 and 95, respectively, so that they can rotate together.

That is, as each of the conveying shafts 31 rotates, the respective forward, middle, and rear conveying members 30a, 30b, and 30c corresponding to the conveying shafts 31 rotate together, (32) and the protruding portion (34) of the cover (30). For example, each of the conveying members 30 may be provided with five depressions 32 and protrusions 34. In this case, the rear conveying member 30c and the center conveying member 30c, The member 30b has an arrangement angle? 1 so as to be shifted by about 24 degrees. The central conveying member 30b and the front conveying member 30a are equally disposed with respect to the arrangement angles of the rear and central conveying members 30c and 30b and each of the conveying members 30a, 30b, and 30c has a different phase difference do.

11 to 14 are views showing the operation of the roll cleaning apparatus shown in Fig. 11 is a view showing a standby position of the roll cleaning apparatus. As shown in Fig. 11, the roll cleaning apparatus 100 can be installed on the upper side of the plating roll 8. As shown in Fig. As described above, the upper housing 10 can move along the longitudinal direction of the plating roll 8 by being movable along the fixed beam 80. An intermediate housing 13 connected to the lower portion of the upper housing 10 and the lower housing 10 by driving the cylinder 88 connected to the upper portion of the upper housing 10 to raise and lower the cylinder rod 89, The housing 17 and the cleaning member 20 can be moved up and down toward the plating roll 8. [ That is, the cleaning member 20 has a standby position spaced apart from the surface of the plating roll 8, and is switchable to an operating position in which the cleaning member 20 is in contact with the surface of the plating roll 8 through the driving of the cylinder 88.

11 to 14 are views showing the operation of the roll cleaning apparatus shown in Fig. As shown in Fig. 12, when the cleaning member 20 is placed in the operating position, the driving rolls 70 are rotated by abutting against the plating roll 8, thereby rotating the conveying members 30. Therefore, when the front drive shaft 35a is placed at the apex of the protrusion 34a by the rotation of the front transfer member 30a, the lower end of the front drive shaft 35a is lowered.

12, the front slave shaft 25a disposed at the lower portion of the front drive shaft 35a is lowered by the front drive shaft 35a, and by the descent of the forward slave shaft 25a, (17) is inclined toward the front pushing shaft (60a). That is, as the lower housing 17 is tilted, the front pushing shaft 60a descends and the cleaning member 20 is shifted to the first operating position in which it tilts forward.

On the other hand, since the driving roll 70 is continuously rotated in contact with the plating roll 8, each of the conveying members 30 also continuously rotates. 13, the front drive shaft 35a rotates the restoring force (elastic force) of the upper elastic member 36 disposed between the roll bracket 37 and the upper housing 10 And moves toward the depression 32a. In this case, the front drive shaft 35a is spaced apart from the front drive shaft 25a disposed at the lower portion, and the front drive shaft 25a is disposed between the driven ring 26 and the intermediate housing 13, (Elastic force) of the lower housing 17 and the upper surface of the lower housing 17 is positioned in parallel with the horizontal direction. As the driven ring 26 is lifted, the front pushing shaft 60a rises through the restoring force (elastic force) of the lower elastic member 19 disposed between the lower housing 17 and the lower limit metering 18, Position.

14, the central conveying member 30b has an arrangement angle deviated from the front conveying member 30a by about 24 degrees, and the center conveying member 30b and the rear conveying member 30c are also shifted by about 24 degrees Respectively. 13 and 14, when the central drive shaft 35b and the central follower shaft 25b are lowered by the central transfer member 30b, the cleaning member 20 is rotated along the vertical direction on the plating roll 8 and the rear drive shaft 35c and the rear slave shaft 25c are lowered by the rear transfer member 30c, the lower housing 17 descends toward the rear pushing shaft 60b, 20 are switched to the third operating position which is inclined rearward.

That is, the present invention can polish the plating roll 8 by sequentially pressing the cleaning member 20 toward the front, the center and the rear using the driving member 40. Further, the roll cleaning apparatus 100 does not need to have a separate energy source by using the rotating force of the plating roll 8 as it is. In particular, by maintaining the contact surfaces of the cleaning member 20 and the plating roll 8 uniformly, the fatigue and wear of the cleaning member 20 can be minimized, thereby maximizing the efficiency and productivity of the plating process.
