TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface rubbing device that rotates in contact with a target surface and applies a physical action such as a wiping action or a polishing action to the target face.
[0002]
[Prior art]
BACKGROUND ART In a building or the like, a floor polishing machine called a polisher is known as a working machine for efficiently performing operations such as floor cleaning and wax removal. This floor polishing machine attaches a circular brush or pad as a surface rubbing tool (floor rubbing tool) to an airframe having a driving source composed of an electric motor or the like and rotates the same, thereby moving the floor surface while moving. It is to clean.
[0003]
In the floor polisher, the floor rubbing tool may be replaced with a new one due to a decrease in polishing performance, or a floor rubbing tool may be replaced with one that performs a different rubbing action on the floor surface according to the work content. It is detachable from the fuselage.
[0004]
In the conventional floor rubbing device, the entire contact portion with the floor surface has a single circular or donut-shaped planar shape centered on the rotation axis (for example, see Patent Document 1).
[0005]

[0006]
[Problems to be solved by the invention]
For this reason, according to the conventional floor rubbing device, when the floor surface has irregularities, there is a problem that the followability to the irregularities is poor, and the finish tends to be uneven.
[0007]
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a surface rubbing tool that has good followability to irregularities on a target surface.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problem, a surface rubbing device according to an embodiment of the present invention is a surface rubbing device that is rotated while being in contact with a target surface, and includes a base and a distribution on the surface of the base. And a plurality of rubbing members (claim 1).
[0009]
In the surface rubbing tool, the plurality of rubbing members are distributed on a surface of the base. Each of the plurality of rubbing members applies a rubbing action to the target surface independently of the other rubbing members. For this reason, each of the plurality of rubbing members can easily follow the unevenness of the target surface, and the rubbing action can be applied to the target surface without unevenness.
[0010]
In the surface rubbing device, the rubbing member includes not only a pad-shaped member but also a brush-shaped member. Further, the base may be a plate or a roll. When the base is plate-shaped, the surface is flat, and when the base is roll-shaped, the surface is a peripheral surface.
[0011]
The shape and size of each rubbing member are arbitrary. The shape and size of all the rubbing members may be the same, or rubbing members of different shapes and sizes may be mixed.
[0012]
As a preferred embodiment, in each of the plurality of rubbing members, a contact portion to the target surface includes a first arc and a second arc at different positions on the outer periphery thereof, and The fixed state of the rubbing member to the base is the first fixed state in which the first arc is positioned forward in the rotation direction of the surface rubbing tool, and the second arc is the rotation of the surface rubbing tool. It can also be possible to change to the second fixed state positioned forward in the direction (Claim 2).
[0013]
The surface rubbing tool is used by positioning any one of the first arc and the second arc in each of the rubbing members in the rotation direction of the surface rubbing tool. The center of the arc is most protruding, and the arc has a smoothly curved shape rearward in the rotational direction, so that the arc can easily follow the concave portion of the target surface, particularly the concave portion. Therefore, the ability to follow the unevenness of the target surface is further improved.
[0014]
By the way, in each of the rubbing members, the portion where the largest rubbing action can be performed on the target surface is the arc portion located forward in the rotation direction. For this reason, the portion of the circular arc is liable to wear quickly. Therefore, by changing each of the rubbing members between the first fixed state and the second fixed state in accordance with the wear thereof, the service life of each rubbing member is at least two times. Extends twice. Therefore, economy is also improved.
[0015]
As a preferred embodiment, each of the rubbing members can be detachably attached to the base with a hook-and-loop fastener (claim 3). With this configuration, it is possible to replace the old and new rubbing members by using the base as it is, thereby further improving economical efficiency. In addition, the operation of attaching and detaching the rubbing members to and from the base can be easily and quickly performed, which is preferable.
[0016]
In addition, when the surface rubbing tool is rotated while the rubbing member is in contact with the target surface, the friction with the target surface causes the rubbing members to move between the rubbing members and the base. A force acts to shift the base along the circumferential direction. However, the hook-and-loop fastener is more favorable because it has a strong resistance to an external force that tends to shift laterally along the joining surface.
[0017]
As a preferred embodiment, the base may be provided with a compressibility capable of promoting the followability of the rubbing member to the target surface (claim 4). This is preferable because each of the rubbing members can independently follow the complicated unevenness of the target surface better.
[0018]
As a preferred embodiment, in each of the plurality of rubbing members, a contact portion with the target surface has an arc bulging forward at least in a part of the outer periphery in the rotation direction of the surface rubbing tool. And at least two of the plurality of rubbing members may have different circular arcs as the circular arc (claim 5).
[0019]
In this case, since the arcs of the at least two rubbing members have different radiuses, by performing the rubbing operation while moving the surface rubbing tool on the target surface, the area (wide area) on the target surface is increased. 3), any one of the at least two rubbing members more easily follows the different concave portions. Therefore, the finish of the rubbing work is improved.
[0020]
As a preferred embodiment, at least two of the plurality of rubbing members are arranged on the base at different distances from a rotation center of the surface rubbing tool. (Claim 6). In this case, by rotating the surface rubbing tool, the at least two rubbing members independently perform rubbing actions on different regions (there may be overlapping regions) of the target surface. Thus, even when the unevenness of the target surface is complicated, the followability to the unevenness is improved.
[0021]
As a preferred embodiment, the plurality of rubbing members are arranged in at least two rows inside and outside in a circumferential direction around the rotation center of the surface rubbing tool, and individual rubbing members constituting an inner row are The rubbing members constituting the outer row may be arranged between adjacent ones of the rubbing members.

In addition, it is optional to arrange any one of the group of large rubbing members and the group of small rubbing members inside (or outside). However, if the group of large rubbing members is arranged outside the group of small rubbing members (claim 10), the following various advantages can be obtained.
[0027]
That is, according to the configuration, when the surface rubbing tool rotates, a relatively outer wide area on the target surface is subjected to a rubbing action by the group of large rubbing members, and a relatively inner narrow area on the target surface. The area is rubbed by the group of small rubbing members. And, inevitably, the peripheral speed at the time of rotation of the group of large rubbing members located on the outside is higher than that of the group of small rubbing members located on the inside. A large area of the surface is efficiently and reliably rubbed.
[0028]
On the other hand, the group of small rubbing members has a smaller rubbing speed and a smaller rubbing area than the group of large rubbing members, but each has a smaller diameter. There is an advantage that it is excellent in follow-up ability. Therefore, by providing both the large rubbing member and the small rubbing member, the two advantages can be obtained at the same time.
[0029]
Further, since the group of large rubbing members is arranged outside the group of small rubbing members, the stability of the surface rubbing tool on the target surface is good. In addition, since most of the load applied to the surface rubbing device is supported by the group of large rubbing members on the outside having a large total contact area with the target surface, the resistance to the load is good, and the rubbing member is good. There is an advantage that the life of the whole is prolonged.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
[0050]
FIG. 1 is an overall perspective view of a rubbing tool according to an embodiment of the present invention, FIG. 2 is a bottom view of the rubbing tool of FIG. 1, and FIG. 3 is an example of a method of using the rubbing tool of FIG. FIG.
[0051]
In the present embodiment, the present invention will be described in detail by taking, as an example, a floor rubbing tool used for polishing and cleaning the floor of a building or the like. Therefore, the surface rubbing tool according to the present embodiment exerts a physical action such as a rubbing action and a polishing action on the floor surface as the target surface.
[0052]
However, the use of the rubbing tool according to the present invention is not limited to floor cleaning. For example, by changing the size and material to appropriate ones for each application, cleaning the inside and outside walls of buildings, cleaning the inner walls of tunnels, cleaning window glass, cleaning the surface of trains and automobiles, and tombstones It can be put to practical use as various types of surface rubbing tools according to the respective applications, such as surface cleaning of roads, road and park surface cleaning, and pool bottom and inner surface cleaning.
[0053]
As shown in FIG. 3, the surface rubbing tool 1 according to the present embodiment is used by being attached to a floor polisher 2 having an appropriate configuration known per se. The body 3 of the floor polishing machine 2 includes a driving source such as an electric motor 5 housed in a housing 4, a rotating disk 7 that is driven to rotate in a plane parallel to a floor 6 by the electric motor 5, A cover 8 fixed to the housing 4 to cover the turntable 7, an operation rod 9 extending obliquely rearward and upward from the cover 8, and a wheel for non-working movement rotatably supported by a rear portion of the cover 8; 10 is provided. An operation panel 12 including a switch and the like of the electric motor 5 is disposed near a T-shaped or the like grip portion 11 connected to the upper end of the operation rod 9.
[0054]
The surface rubbing tool 1 according to the present embodiment is attached to the lower surface 13 of the turntable 7. The surface rubbing tool 1 rotates while being in contact with the floor surface 6 and applies a predetermined rubbing action to the floor surface 6. Therefore, the operator holds the grip portion 11 of the operation rod 9 in his / her hand, and controls the position of the turntable 7 on the floor surface 6 as a surface to be cleaned while efficiently moving the floor surface 6. Can be cleaned. Note that the washing water or the washing liquid may be appropriately used depending on the specific contents or purpose of the floor polishing work.
[0055]
As shown in FIG. 1, the surface rubbing tool 1 includes a base 14 and a plurality of rubbing members 16, 16,... Distributed on a surface 15 of the base 14. Although not limited, the base 14 is a donut-shaped flat plate, and the flat lower surface 15 is provided with the plurality of rubbing members 16, 16. Are provided.
[0056]
As shown in FIG. 3, the base 14 is attached to the lower surface 13 of the turntable 7 such that the center X is aligned with the rotation center of the turntable 7 of the floor polishing machine 2. . The outer diameter of the base 14 is determined according to the outer diameter of the circular lower surface 13 of the turntable 7.
[0057]
The base 14 is formed in a donut shape because the rotating disk 7 of the floor polishing machine 2 has a nut receiving recess (FIG. 1) in the center of its lower surface 13 for receiving a nut for attachment to a rotary drive shaft. (Not shown). Further, the peripheral speed at the time of rotation at a position close to the center X of the base 14 is low, so that even if the pads 16 are provided, a very large rubbing effect cannot be obtained.
[0058]
When the plurality of pads 16, 16,... Are in contact with the floor surface 6, the surface rubbing tool 1 uses the rotating disk 7 as a target surface with the center X of the base 14 as a rotation center. It is rotationally driven in a plane parallel to the floor surface 6. At this time, each of the pads 16, 16... Rubs the floor 6 independently of the other pads 16. Therefore, each of the plurality of pads 16, 16... Can easily follow the unevenness of the floor surface 6, and the floor surface 6 can be rubbed evenly.
[0059]
In the present embodiment, the base 1 has a compressibility that can promote the following of the pads 16 on the floor 6. In this way, the compressibility of each of the pads 16 and the compressibility of the base 14 act in an additive manner. It is possible to better follow up.
[0060]
The base 14 is detachable from the turntable 7 of the floor polishing machine 2. In the present embodiment, a well-known surface fastener is used as a means for detachably attaching the base 14 to the turntable 7. That is, as shown in FIG. 3, on the lower surface of the turntable 7, either one of a male element and a female element f1 forming a pair of hook-and-loop fasteners is fixed, and the flat upper surface 17 of the base 14 is fixed. The other one of the male element and the female element constituting the hook-and-loop fastener, f2, is fixed thereto. Therefore, the work of attaching and detaching the base 14 to and from the turntable 7 can be easily performed.
[0061]
Each of the pads 16 may be formed integrally with the base 14. However, in the present embodiment, as shown in FIG. 1, the base 14 and the pads 16 are formed separately, and they are detachable from each other. Thus, the base 14 can be used as a common one, and only each of the pads 16 can be replaced with a new or old pad according to its wear, or replaced with another pad having a different rubbing action. it can. Therefore, economy is improved.
[0062]
Although not limited, as each of the pads 16, for example, a pad obtained by attaching abrasive grains to a nonwoven fabric can be used. In the pad 16, different types of rubbing action can be exhibited by changing the type of abrasive grains. In addition, a pad that does not have abrasive grains and performs a soft wiping action on a surface can also be used. Therefore, by preparing a plurality of sets of pads exhibiting different types of rubbing action, selecting a type corresponding to the purpose of cleaning and attaching it to the base 14, for example, a mere wiping action, stronger than that Different physical actions can be applied to the floor surface, such as a rubbing action or a polishing action, and a wax peeling action.
[0063]
The rubbing member 16 is not limited to the pad type shown in the figure, but may be a brush type. In this case as well, a plurality of sets of hairs having different hardness and length can be prepared and used in accordance with the work content.
[0064]
In the present embodiment, a known surface fastener is used as a means for detachably attaching the pad 16 to the base 14. That is, any one of the male element and the female element f1 forming a pair of hook-and-loop fasteners is fixed on the entire lower surface 15 of the base 14, and the entire upper surface 18 of each of the pads 16 is One of the male element and the female element f2 of the hook-and-loop fastener is fixed. Therefore, the work of attaching and detaching the pads 16 to and from the base 14 can be easily performed.
[0065]
When the floor polishing machine 2 is driven in a state where the pads 16 are in contact with or pressed against the floor surface 6, the friction between the pads 16 and the floor surface 6 causes the respective pads 16 and the base 14 to be in contact with each other. During this time, a force acts to shift the pads 16 laterally along the circumferential direction of the base 14. However, since the hook-and-loop fastener has a strong resistance to an external force which tends to cause a lateral displacement along the joining surface, there is no concern about lateral displacement even if the pad 16 is small.
[0066]
As another embodiment, each of the pads 16 may be directly attached to the lower surface 13 of the turntable 7 of the floor polishing machine 2 using the hook-and-loop fastener. In this case, the turntable 7 itself functions as the base 14.
[0067]
In a state where the pad 16 is attached to the base 14, the lower surface of the pad 16 becomes a contact portion 19 with the floor 6. In a preferred embodiment, each of the pads 16 has a first arc C1 and a second arc C2 at different positions on the outer periphery of the floor contact portion 19, as shown in FIG. As a specific mode having these requirements, in the present embodiment, the outer peripheral shape (at least the outer peripheral shape) of the floor contact portion 19 of each of the pads 16 is formed in a circular shape.
[0068]
In each of the pads 16, a part of the outer periphery of the floor contact portion 19 is the arc C <b> 1 swelling forward F in the rotation direction of the base 14. Since the center of the arc C1 is the most protruding and has a smoothly curved shape rearward in the rotation direction from the center, the arc C1 can easily follow (easily enter) a particularly small concave portion of the floor surface 6. . Therefore, the following ability of the pad 16 to follow the unevenness of the floor surface 6 is further improved, which is preferable.
[0069]
As described above, in this embodiment, a hook-and-loop fastener is employed as a means for attaching the pads 16 to the base 14. For this reason, the fixing state of each pad 16 to the base 14 can be changed in various ways.
[0070]
For example, as shown in FIG. 2, the pads 16 are fixed to the base 14 so that the first arc C1 is located forward F in the rotation direction of the base 14 at first ( Assume that the floor is polished by the surface rubbing tool 1 (first fixed state). In this case, in each of the pads 16, a portion where the greatest rubbing action can be performed on the floor surface 6 is the portion of the first arc C1. For this reason, the portion of the first circular arc C1 is apt to be worn fastest. Then, from the first fixed state, to the new fixed state (second fixed state) in which the second circular arc C2 is located forward F in the rotation direction of the base 14, the base 14 is The fixed state of each pad 16 can be changed for use. In this way, the service life of each pad 16 is at least doubled. Therefore, it is economical.
[0071]
In particular, in the present embodiment, since each of the pads 16 is circular, the state of fixing to the base 14 is changed three times or more, and arcs of different portions on the outer periphery are sequentially involved in polishing. You can also. In this manner, the service life of each of the pads 16 can be extended three times or more.
[0072]
By the way, due to repeated experiments, the rubbing effect of the surface rubbing tool 1 may vary depending on the mounting position of each pad 16 on the base 14, the number and size of the pads 16 and the like. Do you get it. Therefore, these preferred specific examples will be described below.
[0073]
In the present embodiment, the plurality of pads 16, 16,... Are composed of a group of large-diameter pads 16L, 16L, and a group of small-diameter pads 16S, 16S,. The large-diameter pad 16L is a large rubbing member that applies a relatively wide rubbing action to the floor surface 6 by the rotation of the base 14, and the small-diameter pad 16S is rotated by the rotation of the base 14. It is a small rubbing member that performs a relatively narrow rubbing action on the floor surface 6.
[0074]
Although not limited, the group of small-diameter pads 16S, 16S,... Is desirably arranged side by side in the circumferential direction around the rotation center X of the base. The group of large-diameter pads 16L, 16L... Is arranged outside the group of small-diameter pads 16S, 16S... In a circumferential direction about the rotation center X of the base 14. Is desirable.
[0075]
In the arrangement, an interval is provided between adjacent pads. By providing this interval, the independent followability of each pad 16 to the unevenness of the floor surface 6 is improved. The intervals also function as a discharge path for dirt and cleaning water on the floor 6 scraped off by the pads 16. Therefore, the discharge property of the cleaning water, wax separation debris, and the like is also improved.
[0076]
According to the arrangement of the pads 16, when the surface rubbing tool 1 rotates, a relatively outer wide area on the floor surface 6 is subjected to the rubbing action by the group of large-diameter pads 16L, 16L. , A relatively narrow area inside the floor 6 is rubbed by the group of small-diameter pads 16S, 16S,. Inevitably, the group of large-diameter pads 16L, 16L,... Located on the outside has a faster peripheral speed during rotation than the group of small-diameter pads 16S, 16S,. Therefore, a large area of the floor surface 6 is efficiently and reliably rubbed by the group of large-diameter pads 16L, 16L,.
[0077]
On the other hand, the group of small-diameter pads 16S, 16S... Has a smaller rubbing speed and rubbing area than the group of large-diameter pads 16L, 16L. ), There is an advantage that it is superior to the group of large-diameter pads 16L, 16L,... Therefore, by providing both the large-diameter pad 16L and the small-diameter pad 16S, the two advantages can be obtained at the same time.
[0078]
Also, since the group of large-diameter pads 16L, 16L,... Is arranged outside the group of small-diameter pads 16S, 16S,. good. In addition, a large load corresponding to the weight of the body 3 of the floor polisher 2 is applied to the surface rubbing tool 1, and most of the load is applied to the outer surface having a large total contact area with the floor surface 6. Since it is supported by the group of large-diameter pads 16L, 16L, there is an advantage that the resistance to the load is good and the life of each pad 16 as a whole is long.
[0079]
Furthermore, the large-diameter pad 16L and the small-diameter pad 16S are attached to the base 14 at different distances from the rotation center X of the base 14. Therefore, the rotation of the surface rubbing tool 1 causes the large-diameter pad 16L and the small-diameter pad 16S to independently rub different areas on the floor 6 respectively. Therefore, even when the unevenness of the floor surface 6 is complicated, the followability to that is further improved.
[0080]
According to the rubbing test, when the ratio between the diameter of the large-diameter pad 16L and the diameter of the small-diameter pad 16S was 7: 4, the finish of the rubbing operation was the best.
[0081]
As shown in FIG. 2, individual small-diameter pads 16S constituting the group of small-diameter pads 16S, 16S... Are arranged between adjacent groups of the group of large-diameter pads 16L, 16L. It is desirable to do. In this way, each of the group of large-diameter pads 16L, 16L,... And each of the group of small-diameter pads 16S, 16S,. And the finish of the rubbing work is further improved.
[0082]
The inventors of the present invention, as a comparative example, each of the small-diameter pads 16S located relatively inside the base 14 and the large-diameter pads 16L located relatively outside the base 14. The rubbing test was performed by arranging the centers of the bases 14 so as to be positioned on the radius of the circular base 14. However, in this case, the finish of the rubbing work was worse than in the case of the arrangement according to the present embodiment. This is because the inner small-diameter pad 16S and the outer large-diameter pad 16L are arranged on the radius of the base 14, so that they are inferior in independent followability to fine irregularities on the floor surface. Probable cause. However, even when the inner small-diameter pad 16S and the outer large-diameter pad 16L were arranged on the radius of the base 14, much better rubbing results were obtained compared to the conventional one. Needless to say.
[0083]
Further, as shown in FIG. 2, the group of small-diameter pads 16S, 16S... And the group of large-diameter pads 16L, 16L. Between the radius Tr of the circumscribed circle T and the radius Ur of the virtual inscribed surface U to the group of large-diameter pads 16L, 16L,..., The virtual circumscribed circle radius Tr ≧ the virtual inscribed circle radius Ur Are preferably arranged on the base 14 so that the following relationship is established. In this way, even when the surface rubbing tool 1 rotates at a fixed position on the floor 6, the group of small-diameter pads 16S, 16S, and the group of large-diameter pads 16L, 16L,. This is more preferable because there is no area left to be rubbed between.
[0084]
The surface rubbing tool 1 configured as described above, for example, attaches an appropriate number of replacement pads 16 in a state where the pads 16 are attached to the base 14 in the predetermined arrangement. , Can be sold to consumers. As another selling method, in a state where all the pads 16 are separated from the base 14, the pads can be bundled with the pads and sold together with the base 14 to a customer. In either case, the purchaser (user) needs to place the pad 16 on the base 16 in a predetermined arrangement shown in FIG. 2 when the pad 16 is replaced or newly attached, as shown in FIG. It is desirable to have them properly arranged.
[0085]
For this reason, in the present embodiment, as shown in FIG. 1, the base 14 is provided with a display M for indicating a mounting position of the pads 16. As the display M, for example, a circle corresponding to the contour of each of the pads 16 may be marked on the lower surface 15 of the base 14. In this way, the proper mounting positions of the plurality of pads 16, 16,... With respect to the base 14 are easy to understand, so that the user is kind and convenient.
[0086]
As another specific example of the display M, the hook-and-loop fastener for attaching the pad 16 to the base 14 can be used. That is, a circular surface fastener having a size corresponding to each pad 16 is provided on the lower surface 15 of the base 14 only at the position where each pad 16 is attached.
[0087]
Further, as shown in FIG. 1, in addition to the display M or without the display M, an information transmitting member N having predetermined information on a method of using the surface rubbing tool 1 is attached to the surface rubbing tool. 1, they may be sold as a unit 100. A typical example of the information transmission member N is an instruction manual. By doing so, the user can obtain the predetermined information on the rational use of the surface rubbing tool 1 at the same time as the purchase of the rubbing tool 1, so that the user can use the rubbing tool 1 without any mistakes.
[0088]
In this case, as the predetermined information, information that teaches that each of the pads 16 can be changed and used between the first fixed state and the second fixed state according to the wear thereof, Information indicating the mounting position of each of the pads 16 with respect to the base 14 as shown in FIG.
[0089]
The sales unit 100 may include the base 14 as a component or may not include the base 14. In other words, once the base 14 is purchased, it can be used for a longer period of time than the respective pads 16. Therefore, even if the plurality of pads 16 and the information transmission member N alone are set and sold as a replacement unit. Because it is good. Further, in the present embodiment, each pad 16 can be directly attached to the rotating disk 7 of the floor polishing machine 2 for use. In that case, the base 14 is not necessarily required. is there.
