Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a decontamination device that moves along a floor surface to be worked on and wipes off dust and the like on the floor surface.

<Conventional technology> Various robots suitable for these tasks have been developed for various tasks that require remote control due to space constraints or the possibility of harm to the human body, and floor decontamination equipment has also been developed. This is one of them. Conventional floor decontamination equipment includes a rotating brush and a vacuum suction device, and uses the brush to scrape up dirt on the floor surface to be worked on, and collects the dust with the vacuum suction device. For this reason,
It is not possible to remove even the minute dust adhering to the floor surface, which is a problem that cannot be ignored in nuclear reactor equipment where radioactive dust is a problem, for example.

Therefore, a floor decontamination device for such equipment needs to be equipped with a rag to wipe away the dust on the floor surface being worked on, but currently known devices are equipped with a rag that is fixed so that it forms a flat surface. Since it is a type of cloth that is pressed against the floor surface, if the floor surface to be worked on has unevenness or undulations, the entire surface of the rag may not be pressed against the floor surface, resulting in incomplete wiping of the floor surface. It was hot.

<Problems to be solved by the invention> This invention was devised in view of the above-mentioned conventional problems, and it realizes fine-grained wiping work comparable to manual wiping work, and is capable of cleaning floors with unevenness and undulations. To provide a floor decontamination device that achieves complete wiping even on surfaces.

<Means for solving the problem> The floor decontamination device of the present invention wraps a rag around a pair of rolls supported by a support that moves along the floor surface to be worked on, and further pinches the rag. Then, a plurality of press rollers facing the floor surface and made of an elastic material are successively arranged in a row along a direction intersecting the moving direction of the support, and the row of press rollers is connected to the support roller. Arranged in multiple rows in the direction of body movement,
A resilient means for pressing the rag against the floor is interposed between each of these presser rollers and the support body that supports the presser roller so as to be able to reciprocate in a direction perpendicular to the floor. Shift the positions of the presser rollers in each row to the left and right so that the entire width of the rag is pressed against the floor surface, so that the rag is always pressed against the floor surface even if the work surface is uneven or undulating. It is something that can be done.

<Embodiment> As shown in FIG. 2, which shows a side view of an embodiment of the floor decontamination apparatus according to the present invention, a driving means for moving a wiping device section 2 equipped with a rag 1 along a floor surface 3 The vehicle is equipped with a traveling cart 6 that travels on the floor surface 3 by an endless toothed belt 5 driven by a traveling motor 4. The front and rear ends of the traveling truck 6 are equipped with sliders 8 that can be reciprocated in parallel to the traveling direction of the traveling truck 6 by a swinging motor 9, and the wiping device sections 2 are connected to these sliders 8 via slide mechanisms 7, respectively. Therefore, these wiping device parts 2 can reciprocate in parallel to the floor surface 3, and can also move in the vertical direction.

As shown in FIG. 1a, which shows an enlarged side view of the internal structure of the wiping device shown in FIG. 2, and FIG. includes a support body 10 consisting of a pair of side plates 10a and a support plate 10b spanned between the side plates 10a. On the side plate 10a, a rag roll 11 around which a strip of rag 1 is wound, a rag take-up roll 12 that winds up the rag 1 pulled out from the rag 11, and a guide roller 13 that guides the feeding of the rag 1 run, respectively. When the waste winding roll 12 is rotatably supported at right angles to the running direction of the trolley 6, and is rotated via a belt 15 by a drive motor 14 attached to the side plate 10a, the waste 1 is removed from the waste roll 1.
1 and is guided by a guide roller 13 and wound onto a waste cloth take-up roll 12.
A brake device 16 attached to the side plate 10a is connected to the rag roll 11 via a belt 17, which maintains the feeding of the rag 1 in a stopped state at an arbitrary position and removes slack in the rag 1. I'm starting to get it.

Further, a plurality of substantially U-shaped fixtures 19 are supported on the support plate 10b via pins 18 so as to be movable in a substantially perpendicular direction with respect to the floor surface 3. 19 and support plate 10b
It is always biased toward the floor surface 3 by a spring 20 interposed between the floor surface 3 and the floor surface 3 side. A press roller 21 made of an elastic material such as synthetic rubber or polyurethane foam is rotatably supported on each of these fixtures 19 via a shaft 22, and a plurality of press rollers 21 are arranged in a row. Three rows of rollers 23 perpendicular to the traveling direction of the trolley 6, that is, the moving direction of the wiping device section 2,
24 and 25 are formed, and the rag 1 from the rag roll 11 to the rag take-up roll 12 is brought into close contact with the floor surface 3 and pressed by the biasing force of the spring 20 and the elasticity of the presser roller 21 itself. Here, Fig. 1a
As shown in FIG. 1c, which shows a cross section taken along line A-A and cross-section shown along C-C, and shown in FIG. 23,2
5 and the roller row 24 are disposed in a staggered manner so as to be out of phase with each other in the left and right directions with respect to the moving direction of the wiping device section 2 and overlap each other in the front and back. These pressing rollers 21 press the rag 1 against the floor surface 3 throughout the width direction without any gaps.
That is, as described above, the roller rows 23, 24, 2
By making the width of each presser roller 21 relatively small in 5, it is possible to follow the irregularities and undulations of the floor surface 3 and press the cloth 1 against the floor surface 3, and each roller row 23, 24, 25, gaps in the width direction of the rag 1 that are inevitably caused by the fixtures 19 that hold these presser rollers 21 are eliminated by the front and rear roller rows, and the width of the presser rollers 21 is fixed, that is, within the predetermined wiping width of the wiping device 2. Achieves good work without leaving any residue.

To explain the operation of the floor decontamination device with the above configuration,
The traveling motor 4 is activated to press the rag 1 against the floor surface 3 while the wiping device section 2 is moved together with the traveling cart 6. At the same time, the swinging motor 9 is activated to move the wiping device section 2 back and forth. By moving the robot, it is possible to automatically perform an extremely good wiping operation in which dust is wiped off while scrubbing the floor surface. At this time, as a matter of course, the drive motor 14 is operated so that the clean cloth 1 is pressed against the floor surface 3 so that the cloth roll 11 is pressed against the floor surface 3.
The dirty rag 1 is wound up on a rag take-up roll 12. Further, during the above-mentioned wiping work, if there are small irregularities on the floor surface 3, the presser roller 21 is bent, and if there are even larger irregularities, the presser roller 21 moves up and down to move the cloth 1 onto the floor surface 3.
In addition, even if there are large irregularities that cannot be absorbed by the vertical movement of the presser roller 21, such as a manhole cover, the wiping device section 2 is moved up and down by the slide mechanism 7, so the wiping device 2 is moved up and down so that the wiping cloth 1 can be kept on the floor. 3 can always be pressed.

Note that, as described above, it is naturally possible to perform the wiping operation by using only one of the movements of the traveling trolley 6 and the reciprocating movement of the wiping device section 2 itself, without using both of them. In addition, in cases where the wiping device section 2 cannot be moved, such as at a corner near a wall, the drive motor 14 may be operated while the wiping device section remains stationary without moving using both of the above. The floor surface 3 can be wiped by feeding the cloth 1 while rotating the presser roller 21, and even during such wiping work, the elasticity of the presser roller 21 keeps the cloth 1 in close contact with the floor surface 3. wiping is done well.

Incidentally, the above-mentioned traveling of the traveling cart 6 and the reciprocating mechanism using the swinging motor 9 are both driving means of the wiping device section 2, but the present invention is not limited to this. Any means that moves the wiping device section 2 so that it can be used may be used. Also, the number of presser rollers and roller rows,
The size etc. are appropriately set depending on the width of the rag, the wiping width, etc.

<Effects of the invention> According to the floor decontamination device according to the invention, the rag is pressed onto the floor surface to be worked on without any gaps using a plurality of rows of rollers composed of presser rollers made of elastic material, so that manual work is not required. A fine-grained wiping work comparable to a rag work can be automatically performed, and complete wiping can be achieved even when working on an uneven or undulating floor surface.
