Accordingly, the foreign substances adhering to the upper roll 5a and the lower roll 5b are removed to prevent quality defects (slippery scratches, scratches, imperfect scratches, and the like) generated during the production of the screed.

4 to 6, a roll cleaning apparatus 1 according to a preferred embodiment of the present invention includes a main body 100, an upper cleaning unit 200, a lower cleaning unit 300, a rotation motor 400, And an elastic portion 500.

Here, each of the upper cleaning device 200 and the lower cleaning device 300 may include rotary brushes 210 and 310.

The main body 100 is provided with an upper cleaning device 200, a lower cleaning device 300, a rotation motor 400 and an elastic part 500. The upper cleaning device 200 and the lower cleaning device 200 are fixed by the elastic part 500, Each of the cleaning devices 300 is in close contact with the upper roll 5a and the lower roll 5b, respectively.

The rotary brushes 210 and 310 installed in the upper cleaning device 200 and the lower cleaning device 300 are driven by the rotary motor 400 so that the rotary brushes 210 and 310 are rotated Thereby removing the foreign matter adhered to each of the roll 5a and the lower roll 5b.

Referring to FIG. 5, the rotary brushes 210 and 310 may include rotary brushes 211 and 311 and rotary brush drive shafts 212 and 312. The rotary brush driving shafts 212 and 312 may be connected to the rotary motor 400 using a link or a gear device so as to receive the rotary force of the rotary motor 400. [

5, the rotary brushes 210 and 310 are arranged in such a manner that a plurality of rotary brushes 211 and 311 can be closely contacted to the outer circumferential surfaces of the upper roll 5a and the lower roll 5b, Type < / RTI > type.

That is, the rotary brush driving shafts 212 and 312 provided between the rotary brushes 211 and 311 are rotated by the rotary brushes 211 and 311 during the rotation of the rotary brushes 211 and 311, And may be installed in the same shape as the universal joint so as to be in close contact with the outer circumferential surfaces of the respective guide grooves 5b.

4A and 4B, each of the upper cleaning device 200 and the lower cleaning device 300 having the rotary brushes 210 and 310 is rotated by an elastic part 500 5a and the lower roll 5b, respectively.

The elastic part 500 includes an upper guide 510 connected to the upper cleaning device 200 by a connecting member, a lower guide 520 connected to the lower cleaning device 300 and an upper guide 510, And an elastic member 530 installed between the lower guide 520.

The elastic member 530 is provided between the upper guide 510 and the lower guide 520 so that the upper guide 510 and the lower guide 520 can be separated from the upper roll 5a and the lower roll 5b Respectively. Here, as the elastic member 530, a spring or the like may be used.

The roll cleaning apparatus 1 according to the preferred embodiment of the present invention may further include moving parts 600a and 600b and a guide roller 700. [

Referring to FIGS. 4A and 4B, the moving parts 600a and 600b may be installed in at least one of the upper guide 510 and the lower guide 520. FIG.

The moving parts 600a and 600b may include a frame 610, a motor 620, and a moving roller 630.

The frame 610 is installed between the lower guide 520 and the motor 620, as shown in Figs. 4A, 4B and 6. That is, the frame 610 is installed in the lower guide 520 to support the motor 620.

A moving roller 630 is installed on the shaft of the motor 620.

As the motor 620 is driven, the moving roller 630 in close contact with the lower roll 5a is rotated.

Depending on the installation positions of the moving parts 600a and 600b, the roll cleaning device 1 according to the preferred embodiment of the present invention may be arranged in the longitudinal direction of the roll (axial direction of the roll) or in the circumferential direction of the roll As shown in Fig. In more detail, the roll cleaning apparatus 1 reciprocates along the roll length direction or reciprocates along the roll circumferential direction along the direction of the rotation axis of the movement roller 630 of the movement units 600a and 600b .

Referring to FIG. 4A, the moving unit 600a is installed so that the roll cleaning apparatus 1 can reciprocate along the roll length direction. In other words, the roll cleaning device 1 is allowed to reciprocate along the roll longitudinal direction by allowing the rotary shaft of the moving roller 630 to cross perpendicularly to the rotary shaft of the rolls 5a and 5b.

Referring to FIG. 4B, the moving part 600b is installed so that the roll cleaning device 1 can reciprocate along the circumferential direction of the roll. That is, by setting the rotating shaft of the moving roller 630 in the same direction as the rotating shaft of the rolls 5a and 5b, the roll cleaning device 1 can reciprocate along the circumferential direction of the roll.

Accordingly, the roll cleaning apparatus 1 according to the preferred embodiment of the present invention moves along the movement path of the slab.

As shown in FIG. 2, a plurality of lower rolls 5a are provided adjacent to each other. Therefore, the roll cleaning device 1 according to the preferred embodiment of the present invention by the moving part 600b includes a plurality of upper rolls (5a) and the lower roll (5b).

The roll cleaning device 1 can reciprocate along the movement path of the slab in accordance with the rotational direction (clockwise or counterclockwise) of the motor 620 of the moving part 600b.

The guide roller 700 may be installed on at least one of the upper guide 510 and the lower guide 520, as shown in FIG. 4B.

The guide roller 700 may be formed in a shape other than the motor 620 in the moving part 600b. That is, the guide roller 700 may include a frame 710 and a guide roll 720.

Therefore, as the roll cleaning apparatus 1 moves by the moving part 600b closely attached to the lower roll 5b, the guide roller 700 also moves closely to the upper roll 5a. Thus, since the upper guide 510 and the lower guide 520 are separated from the upper roll 5a and the lower roll 5b, the roll cleaning device 1 can be easily moved.

4B, the lower guide 520 is provided with a moving part 600b, and the upper guide 510 is provided with a guide (not shown) It is needless to say that the moving part 600b may be installed in each of the upper guide 510 and the lower guide 520. [

The operation principle of the roll cleaning apparatus 1 according to the preferred embodiment of the present invention having the above structure will be described. The upper roll 5a and the lower roll 5b are cleaned by the elastic part 500, The apparatus 200 and the lower cleaning apparatus 300 are brought into close contact with each other to easily remove foreign matter adhered to the upper roll 5a and the lower roll 5b.

Further, when the roll cleaning apparatus 1 is moved, the rollers 600a and 600b and the guide rollers 700 reciprocate along the roll longitudinal direction or the roll circumferential direction.

Particularly, when moving in the circumferential direction of the roll, the upper cleaning device 200 and the lower cleaning device 300 are separated from the upper roll 5a and the lower roll 5b by the moving part 600b and the guide roller 700, Therefore, the roll cleaning device 1 can be easily moved.

As used in this embodiment, the term " portion " refers to a hardware component such as software or an FPGA (field-programmable gate array) or ASIC, and 'part' performs certain roles. However, 'part' is not meant to be limited to software or hardware. &Quot; to " may be configured to reside on an addressable storage medium and may be configured to play one or more processors.
