(Steel plate cleaning method)
Next, a procedure for cleaning the steel plate 12 using the steel plate cleaning apparatus 10 of this embodiment will be explained using FIGS. 9 and 10.

First, the steel plate 12 is transported by, for example, a forklift, and placed on the rail member 14 of the steel plate cleaning device 10 from the other end of the support member 30 in the installation direction. At this time, as shown in FIG. 10, the back surface of the steel plate 12 is supported by the plurality of support members 30, and the end surface abuts against the contact surface 38A of the abutment block 38 of the contact member 34, so that the rail member 12 positioned above. Note that, as shown in FIG. 9(A), the frame unit 16 is disposed at one end in the extending direction of the rail member 14, which is the initial position.

Next, a control panel (not shown) provided in the frame unit 16 is operated wirelessly using, for example, a remote control to start the steel plate cleaning apparatus 10. Then, the steel plate cleaning device 10 is operated based on a preset program to clean the steel plate 12.

Specifically, the upper brush motor 57 (see FIG. 7) rotates the upper brush roll 48A, and the lower brush motor 78 (see FIG. 8) rotates the lower brush roll 48B. Then, the frame unit 16 is moved along the rail member 14 by the frame moving motor 102, and the rotating pair of brush rolls 48 are brought into contact with the front and back surfaces of the steel plate 12, respectively, and brushed, thereby removing the particles that have adhered to the steel plate 12. Scrape off dirt such as mud.

Here, in this embodiment, as shown in FIG. 9(B), when cleaning the steel plate 12, the upper brush roll 48A is moved in the opposite direction (arrow S direction) to the horizontal movement direction (arrow R direction) of the frame unit 16. ). On the other hand, the lower brush roll 48B rotates in the same direction (arrow T direction) as the horizontal movement direction (arrow R direction) of the frame unit 16.

When the frame unit 16 horizontally moves to the other end in the extending direction of the rail member 14, a detection means (not shown) installed on the frame unit 16 detects the sensor 46 installed on the rail member 14, and the frame unit 16 changes direction. Ru.

Then, while cleaning the steel plate 12 again, the frame unit 16 is horizontally moved along the rail member 14 from the other end in the extending direction of the rail member 14 to one end in the extending direction. When the frame unit 16 returns to the initial position shown in FIG. 9(A), the program ends and the steel plate cleaning apparatus 10 stops.

Through the above procedure, the steel plate 12 is cleaned by the steel plate cleaning device 10. Note that the above procedure is an example, and the order may be different or other procedures may be included. For example, in the above procedure, the frame unit 16 is configured to reciprocate along the rail member 14, but it may be configured to stop at the other end in the extending direction of the rail member 14 without reciprocating.

In addition, the moving speed of the frame unit 16 is different when the rail member 14 of the frame unit 16 moves from one end in the stretching direction to the other end in the stretching direction, and when it moves from the other end in the stretching direction to one end in the stretching direction. A configuration may also be adopted in which the direction of rotation of the brush roll 48 is changed.

(action, effect)
According to the steel plate cleaning apparatus 10 of this embodiment, by rotating the brush roll 48 that is pivotally supported by the frame unit 16 while horizontally moving the frame unit 16 along the rail member 14, the brush roll 48 can be used to clean the rail member. The steel plate 12 placed on the steel plate 14 can be cleaned.

That is, since the brush roll 48 is moved to the steel plate 12 side, compared to a structure in which the steel plate 12 is moved to the brush roll 48 side, there is no need to transport the steel plate 12, and the steel plate 12 is not tilted or distorted. In addition, the overall length of the steel plate cleaning apparatus 10 can be shortened.

Further, according to the present embodiment, the brush roll 48 includes an upper brush roll 48A and a lower brush roll 48B. Therefore, the upper brush roll 48A can clean the front surface of the steel plate 12, and the lower brush roll 48B can clean the back side of the steel plate 12, making it possible to clean both sides of the steel plate 12 at once without turning the steel plate 12 over. I can do it.

Further, according to the present embodiment, the pair of brush rolls 48 are each fixed to the frame unit 16 while being allowed to move in the vertical direction by the gap adjustment mechanisms 64, 66, 86, and 88. Therefore, even when cleaning a deformed steel plate 12, for example, the pair of brush rolls 48 can follow the surface shape of the steel plate 12, and the cleaning performance of the steel plate 12 can be improved.

In particular, according to this embodiment, the gap adjustment mechanisms 66, 88 on the arm portions 54B, 56B side of the upper support frame 54 and lower support frame 56 have coil springs 66B, 88B. Therefore, by biasing the pair of brush rolls 48 toward the steel plate 12 by the coil springs 66B and 88B, the brush rolls 48 can be pressed against the front and back surfaces of the steel plate 12 with a predetermined pressure, thereby cleaning the steel plate 12. Performance can be further improved.

Further, according to this embodiment, when cleaning the steel plate 12, the upper brush roll 48A rotates in the opposite direction to the horizontal movement direction of the frame unit 16, and the lower brush roll 48B rotates in the opposite direction to the horizontal movement direction of the frame unit 16. rotate in the same direction.

In this way, by rotating the upper brush roll 48A in the opposite direction to the horizontal movement direction of the frame unit 16, dirt such as mud scraped by the upper brush roll 48A is suppressed from scattering on the surface of the cleaned steel plate 12. can do. Further, by rotating the lower brush roll 48B in the horizontal movement direction of the frame unit 16, resistance when the frame unit 16 moves horizontally can be reduced.

Further, according to the present embodiment, since the support member 30 and the abutment member 34 are provided on the rail member 14, the back surface of the steel plate 12 is supported by the support member 30, and the end face of the steel plate 12 is supported by the abutment member 34. By abutting against the rail member 14, the steel plate 12 can be positioned on the rail member 14. In particular, according to this embodiment, since the coil spring 40 is provided between the abutting block 38 of the abutting member 34 and the fixing part 36, the end face of the steel plate 12 is abutted against the abutting surface 38A of the abutting block 38. It can soften the impact when bumping into the object.

Further, according to the present embodiment, since the hair styling member 42 is provided on the outer periphery of the contact surface 38A of the abutment block 38, the flow of the brush bristles 52 of the brush roll 48 can be adjusted by the hair styling member 42. I can do it.

Specifically, as shown in FIG. 10, the axial length L1 of the brush roll 48 is larger than the width L2 of the steel plate 12. For this reason, when the steel plate 12 is cleaned by the brush roll 48, the brush bristles 52 at the axial end of the brush roll 48 may come into contact with the abutment member 34, causing the bristles 52 to vary.

At this time, since the hair styling member 42 extends diagonally outward from the outer periphery of the abutment surface 38A of the abutment block 38, the scattered brush bristles 52 are arranged along the hair styling member 42. 52 is suppressed. Thereby, it is possible to suppress the fact that the brush bristles 52 of the brush roll 48 vary and the cleaning efficiency of the steel plate 12 decreases.

(Other embodiments)
Although an example of an embodiment of the present invention has been described, the present invention is not limited to this embodiment, and various other embodiments are possible within the scope of the present invention.

For example, in the above embodiment, the frame unit 16 is provided with a pair of brush rolls 48, an upper brush roll 48A and a lower brush roll 48B. However, one brush roll may be provided only on either the upper side or the lower side of the frame unit 16, and one side of the steel plate 12 may be cleaned by this single brush roll.

Alternatively, a configuration may be adopted in which an injection device (not shown) is provided in the frame unit 16 and the injection device injects low-pressure water onto the steel plate 12 from which dirt such as mud has been scraped off. By using both the cleaning by the brush roll 48 and the jetting of low-pressure water, the cleaning ability of the steel plate 12 can be further improved, and the diffusion of dust and the like can be suppressed.

Alternatively, the frame unit 16 may be provided with a blower (not shown) that blows wind. By applying wind to the steel plate 12 using a blower, dirt such as mud scraped off from the steel plate 12 can be blown away in a predetermined direction, and the cleaning ability of the steel plate 12 can be further enhanced.
