(Points of interest)
Rotating brushes used for so-called floor polishers that efficiently clean floor surfaces such as concrete and tiles in buildings and exteriors are generally virtual on the flocked surface of a disk-type brush stand. Either a plurality of flocked holes are drilled radially or virtually concentrically at a predetermined pitch, or a plurality of flocked holes are drilled at the same vertical and horizontal pitch across the entire surface of the flocked surface. It is intended to plant brush bristles in each flock hole arranged in any of them, such as a concentric circle that matches the rotation direction of the brush, or a direction orthogonal to the rotation direction, Or, it is general that the brush hair is planted so as to be evenly arranged with respect to the entire surface of the planted surface irrespective of the rotation direction. Hair arrangement In the effective radius range of the rotating brush, the number of brush hairs passing through the radius range will be coarse and dense, producing a part where many brush hairs pass and a part where brush hairs do not pass so much, Concentric contact irregularities are left behind, and when used for processing such as polishing, grinding, and deburring, concentric processing traces are generated, cleaning unevenness in cleaning and cleaning, and uneven coating in painting operations, etc. This has the disadvantage of reducing the quality and stability of the work.

    In order to eliminate these disadvantages, it has been widely used as a conventional technique to eliminate unevenness of contact by planting brush hairs without any gaps and to enable more uniform cleaning. When planted, dust and dust generated in the work process, cleaning agents, paint, etc. are involved, causing clogging between the brush hairs, greatly reducing work capacity, cleaning and replacement of rotating brushes, etc. On the other hand, there was a drawback that a great deal of labor and cost would be required for maintenance.

(Conventional technology)
Proposals that reflect this situation and serve as a breakthrough are not unheard of.
For example, as typified by what is proposed in Patent Document 1 (1) below, a rotation guide ring is arranged at each end of a revolving arm branched into a plurality from the rotation drive shaft, and a brush is attached to each rotation guide ring. Each of the brushes rotates with the rotation guide ring and revolves around the rotation drive shaft by the revolving arm. Even if the rotation drive shaft rotates at a low speed, cleaning unevenness and reattachment of foreign matter are assumed. A long channel brush is fixed in a spiral shape on the brush table flocking surface, as seen in Patent Document 1 (2), and there is no change in brush strength due to the seam. In some cases, a uniform and high strength can be maintained.

However, since the brush devices having the rotation and revolution mechanisms as shown in the former Patent Document 1 (1) require a complicated mechanism to rotate the brush, a dedicated rotation device is indispensable. There is a drawback that it becomes momentary and expensive, and the one having a long spiral brush as in the latter patent document 1 (2) has one channel brush that is continuous in a spiral band shape. Since the tip of the spiral is eccentric with respect to the center of rotation, it is difficult to stably control the center of rotation when cleaning or polishing, and it is difficult to guide the brush to the target position. It has the disadvantages.

(Awareness of problems)
As described above, various brush rotating mechanisms and rotating brushes that have been proposed in the past have the advantage of being able to prevent the occurrence of concentric contact unevenness, but both are complicated and expensive. In addition, the channel brush arranged in a spiral band has an eccentric arrangement with respect to the center of rotation, leaving a difficulty in operability. Improves flocking workability by work and can be produced more efficiently. Especially, in place of decontamination work in the area affected by the Fukushima Daiichi Nuclear Power Plant accident, instead of a deck brush that has been used by many people, Rotation that can be easily used by anyone so that it can be easily mounted on many commercially available rotating tools, etc. To be able to provide in an early as possible the brush was keenly and must shall be completed more efficiently and rapidly decontaminated.

(Object of invention)
Therefore, the present invention eliminates concentric rotation contact unevenness without requiring a complicated rotation drive mechanism and the like, and prevents clogging and uneven wear of the brush to balance the contact resistance with respect to the rotation axis, thereby rotating the rotation. A new rotating brush that improves the operation and inductivity of the brush that can be manufactured at low cost and can be easily mounted on many commercially available rotating tools. Judging whether it is possible to develop the technology, we started the development and research very quickly, and as a result of repeating trial and error over many years and many trial productions and experiments, this time finally the disc type brush with a new structure In the following, the configuration thereof will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As will be clearly understood from the embodiments representing the present invention shown in the drawings, the disc-type brush of the present invention basically comprises the following configuration.
That is, it has a connecting part set in the shape and size that can be attached and tightened to the rotary blade attachment part of the brush cutter in the center of the back surface, so that it can be attached to the rotary blade attachment part and operated. A brush base having a disk body having an outer diameter of 125 mm and a flocking surface opposite to the back surface is provided, and the brush base flocking surface is closer to the circular center of the flocking surface than the connection portion. The outer periphery is defined as one end, and the radius of curvature gradually increases in the clockwise direction from there to the other end that reaches the outer peripheral edge of the substantially disc body, and is regulated so as to make one round of the disc body. The same shape as either a single-row brush row in which brush hairs are planted in a predetermined bristle length and a predetermined bristle width along the virtual vortex curve, or a plurality of parallel brush rows 3 Article Uzujo units brush bristle, is positioned in the plant hair surface center around each other Each end cross, with an equal phase-like arrangement around the circumference with the opening angle to balance the 120 °, a predetermined width ensure eddy linear gap for preventing clogging between the Uzujo unit hole row radially adjacent It is a disk type brush which makes the composition constituted as a summary.

    As described above, according to the disk-type brush of the present invention, unlike conventional ones, a plurality of brush bristle rows are arranged concentrically on a conventional flocking surface from the unique characteristic configuration as described above. As a result, a difference in strength occurs in the contact pressure of each brush row so that a concentric layer is formed from the center to the centrifugal trap, and as a result, multiple concentric layered contact traces are formed on the surface of the contact object. However, the bristle of each spiral unit brush bristle row of the present invention is planted along a virtual spiral curve in which the radius of curvature gradually increases from the rotation center toward the centrifugal trap. Therefore, it can be used for various operations such as polishing, grinding, cleaning, cleaning, deburring, painting or brushing without leaving concentric contact marks on the surface of the contacted object. In the same shape swirl unit brush hair Are arranged in a uniform phase around the circumference with an opening angle that is balanced around the center of the flocked surface, compared to one in which only one swirl unit brush bristle row is implanted. The contact traces of the brush bristles can be made to be remarkably homogeneous, and each swirl unit brush bristle, each of which is arranged in an eccentric manner, has the contact frictional force with the contacted object surface as a center. Will be balanced so that the rotating disc-shaped brush can be controlled stably and easily by the operator, achieving higher work efficiency and work quality without requiring special skillful operation. Further, it is possible to obtain an excellent feature that durability can be remarkably increased by suppressing uneven wear of brush hairs.

    In addition, since a predetermined width is secured between the spiral bristle rows adjacent to each other in the radial direction, the surface of the contacted object comes into contact with the rotation of the disk-type brush. The centrifugal force that acts on the dust, dust, etc. collected by each swirl unit brush row and the dust itself, and the pushing force in the centrifugal direction due to the arrangement shape on the swirl curve of each swirl unit brush row Thus, the disc-shaped brush is automatically discharged one after another toward the outer side of the disc-shaped brush along the vortex-like gap. An extremely large effect is achieved that a reliable clogging prevention effect that could not be achieved can be achieved.

    Furthermore, the disc-type brush of the present invention has a predetermined bristle length and a predetermined bristle width along a plurality of virtual vortex curves so as to be arranged in a uniform phase around the circumference with an opening angle balanced around the center of the flocked surface. Since the brush hairs are implanted, the number of brush hairs implanted is smaller than that of a conventional type having a plurality of concentric brush rows or one spiral brush row. Even if it is greatly reduced, it becomes possible to achieve contact performance equivalent to or better than that of the conventional type. For example, even when the number of brush bristles is reduced by 20%, polishing, grinding, It is possible to demonstrate the unique performance of maintaining various work efficiency such as cleaning, cleaning, deburring, painting, or brushing at the same level or higher. Brush that ensures the same level of performance When manufacturing, both the number of flocking holes drilled on the brush table flocking surface and the number of manual flocking man-hours are both reduced by 20% or more, greatly reducing production costs, compared to conventional equivalents. The excellent effect of being able to provide the market as a much cheaper product can be demonstrated.

    The outer diameter of the brush base is set to be equal to or less than the diameter of the rotary blade of the brush cutter, and the connection part is set to a shape and size that can be attached and tightened to the rotary blade mounting part of the brush cutter. The brush cutter that is widely used exclusively for weeding work can be used for cleaning the outer walls of buildings, roofs, paved roads, etc., and until now it is not possible to rely on human power using deck brushes etc. It is considered that the cleaning work that could not be done can be made much more efficient and the labor burden can be greatly reduced, especially when performing decontamination work in a vast area after an accident at a nuclear power plant by human sea tactics However, it is possible to make it possible to use a brush cutter that is generally commercially available as a washing machine, and to greatly accelerate the decontamination work that does not proceed slowly.

    In addition, there are various commercially available tools in which the brush base connection portion has a socket insertion portion shape for impact wrench, a bit insertion portion shape for an electric screwdriver, and / or a mounting portion shape for a chuck of an electric drill. Can be easily integrated into any other tool and can be easily combined with existing tools that are widely used in various factory and daily work, so there is no need for special tools. However, there is an advantage that it can be easily used at low cost.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The brush base can be mounted on the rotating part of any of the rotary drive devices, and is on a virtual plane (more specifically, a flocked surface) perpendicular to the rotation center and opposite to the rotary drive device. Crossing the function of enabling the bristle of appropriate material and shape to be integrated into a protruding shape, and resisting the abutment pressure even when the bristle abuts and rotates against the contacted object In addition, it must be made of a material capable of ensuring rigidity capable of maintaining a flat plate shape, and set to a shape and size, and as shown in Examples described later, Alternatively, the back surface should have a connecting portion that can be concentrically connected to the rotating portion of the rotary drive device, and the reverse side of the back surface should be a flocked surface, but a spiral unit brush row to be described later Grooves and holes, penetrating long holes and long grooves, etc. were provided in areas other than the range where multiple strips were provided In addition, the outer diameter is set to be equal to or less than the diameter of the rotary blade of the brush cutter, and the connection portion is set to a shape and size that can be attached and tightened to the rotary blade mounting portion of the brush cutter.

    The virtual vortex curve assumes the placement position of the brush bristles on the brush table flocking surface, assumes the planting target and the target function, and rotates clockwise from the appropriate position near the circular center of the flocking surface to the centrifugal trap. Or one of the counterclockwise direction, the radius of curvature must be set to gradually increase, and a plurality of spiral unit brush rows arranged on the same brush stand flocking surface, They should consist of the same virtual vortex curve, and be arranged in a uniform phase around the circumference with an opening angle that balances around the center of the flocked surface.

    The swirl unit brush bristles share the function of allowing the bristles arranged in a spiral shape to come into contact with the surface of the object as the brush base rotates, along the virtual spiral curve set on the brush base flocking surface. It must be either a single-row brush row in which brush hairs of a predetermined bristle length and a predetermined bristle width are planted, or a plurality of parallel brush rows, and swirls of the same shape A plurality of strips of unit brush bristle rows should be arranged in an even phase around the circumference with an opening angle balanced around the center of the flocked surface. A plurality of parallel brush bristles are formed by arranging brush bristles in a sub-row shape. For example, two or more bristles are arranged in parallel. Or a plurality of brush hair bundles Contact brush bristles group that has been implanted in can be such as those formed by implanted at a predetermined pitch along a virtual spiral curve.

    The brush bristles rotate integrally with the brush table flocking surface and share the function of enabling friction, polishing, grinding, cleaning, brushing, painting, etc. in contact with the contacted object, more specifically, Depending on the purpose of use, synthetic resin, natural fiber, metal bundled wire or fiber material, soft or hard synthetic resin, foam synthetic resin, etc., column, block, rail, columnar Or it can be made of various materials such as a bundle of linear materials, and does not necessarily have to be planted in the flock hole, for example, it is integrated at the same time as the brush stand is molded In addition to being integrated by welding, bonding, etc., it can also be made of sponge or urethane foam continuously integrated into a rail shape extending along a virtual spiral curve. .

    The flocking hole shares the function of allowing the bristles to be planted along the virtual spiral curve of the brush table flocking surface, and turns clockwise or counterclockwise from the appropriate position near the circular center of the flocking surface to the centrifugal trap. It must be perforated in either direction around the imaginary spiral curve set to gradually increase the radius of curvature, and must be perforated at a predetermined pitch. In addition to being able to be planted by applying a retaining stopper without penetrating, as shown in the examples described later, penetrating the plate thickness of the brush base, the diameter of the planted surface is large, On the other hand, the back surface of the flange is set smaller than the opening diameter of the flange to form a brush hair tightening hole. Place the tightening wire along the flocking hole) The middle part of the tightening wire that passes from the tightening hole for bristles through the flocking surface flocking hole and the middle part of the bristles that are bent into the V-shaped or U-shaped bristles inserted into the flocking hole from the side Can be planted so as to bind the bristles in a continuous manner following the virtual vortex curve, and along the virtual vortex curve on the brush base flocking surface. It is possible to use either a single hole array formed by a plurality of holes at a predetermined pitch or a multiple parallel hole array.

    The vortex unit hole array is either a single hole array formed by drilling a plurality of flock holes at a predetermined pitch along a virtual spiral curve, or a plurality of parallel hole arrays. The unit hole array has a function of making it recognizable as a group of unit hole arrays, and as shown in the embodiments described later, the swirl unit hole arrays have an opening angle that balances around the center of the flocked surface. It can be configured to have a uniform phase arrangement around the circumference.

The vortex-like gap ensures a gap between each spiral unit hole row, and after brush hairs are implanted in each flock hole, a gap space can be secured between each spiral unit brush row, so that polishing and grinding can be performed. When used for cleaning, cleaning, painting, brushing, etc., it shares the function that can prevent clogging between each swirl unit brush bristle row, and at least each swirl unit hole row Between the virtual spiral curves, a gap should be ensured so as to be continuous in a spiral band having a substantially constant width.
