  A conventional washing brush for a car washing machine and a car washing machine equipped with the washing brush have been disclosed, for example, as a technique having the characteristics as described above, but in the technique disclosed in Japanese Patent Application Laid-Open No. 2006-62484. Reduces the amount of expensive non-woven fabric used for the brush piece, and realizes low cost and uses a foamed synthetic resin piece with excellent elasticity for the mounting base of the rotating body. Therefore, the brush piece can be brought into contact with the vehicle body that is the surface to be cleaned, so that a high cleaning effect can be obtained. However, during the car wash, the nonwoven fabric piece located at the tip of the brush piece absorbs water and becomes heavy, increasing the load during rotation of the foamed synthetic resin piece located at the mounting base of the rotating body, and gradually. The bristles of the brush pieces are lost, and when they are rotated, the brush pieces are wound around the rotating body and the working radius is reduced. For this reason, it is difficult for the brush pieces to continuously contact the vehicle body, and there is a problem that unwashed parts are generated in the vehicle body and a high cleaning effect cannot be maintained for a long period of time.

Sectional drawing of (a), FIG.6 (a), FIG.6 (b), and FIG.6 (c) are top views of the brush piece in other embodiment.

  1 (a) and 1 (b), a washing brush 1 for a car wash machine is formed by bending a brush piece 3 and a reinforcing material 4 at substantially the center and overlapping the reinforcing material 4 on the back surface of the brush piece 3. The brush body 2 is inserted into protruding groove portions 6 provided at four locations on the outer periphery of a substantially cylindrical shaft body 5 made of a metal material such as aluminum, and fixed by a rivet 10. It is. The brush piece 3 is formed by integrating an upper brush piece 7 located in the vicinity of the cleaning side and a lower brush piece 8 located on the shaft body 5 side via a joint 9 by sewing, and is folded so as to have an approximately M-shaped cross section. Is formed. The brush piece 3 may be folded so as to have an approximate N-shaped cross section in addition to the approximate M-shaped cross section. Moreover, the groove part 6 provided in the outer peripheral surface of the shaft body 5 can be set in a timely manner according to the purpose of use, such as 6 places, 8 places, 12 places, etc. in addition to 4 equally divided places.

  Next, a method of forming the brush body 2 will be described with reference to FIGS. 2 (a) to 2 (d).

  In FIG. 2 (a), the brush piece 3 first superimposes one end of the flat upper brush piece 7 and one end of the flat lower brush piece 8, and the lower brush piece 8 One end portion of the other upper brush piece 7 is superimposed on the other end portion, and is formed in a generally elongated plate shape integrated through a joint portion 9 by sewing. In addition, mounting holes 11 formed of a Thomson type or the like are provided at four equally divided portions in the substantially central portion of the lower brush piece 8 in the longitudinal direction. Next, the brush piece 3 folds the substantially central portion in the short direction in the valley, and then folds the substantially central portion in the short direction of the two surfaces that are folded in the valley to form two space portions 31. At the same time, the four mounting holes 11 are overlapped and formed to have an approximately M-shaped cross section. In addition to the sewing, the joining portion 9 may be formed by a physical joining method such as screwing, riveting, hook-and-loop fastener, weaving, or a chemical joining method such as adhesion, welding, or fusion. Absent.

  In FIG. 2B, the reinforcing material 4 is a hollow portion 13 in which a polyolefin-based resin such as ethylene vinyl acetate, ethylene methyl acrylate, ethylene ethyl acrylate, ethylene butyl acrylate, ultra low density polyethylene, low density polyethylene, or polypropylene is foamed. It consists of a synthetic resin foam having a substantially cylindrical shape. The synthetic resin foam preferably has countless closed cells with low water absorption. The reinforcing material 4 has a mounting hole 12 at a substantially central portion in the longitudinal direction, and the mounting hole 12 penetrates toward the facing surface of the reinforcing material 4.

  The reinforcing material 4 is manufactured by the following procedure. First, a polyolefin resin, a foaming agent, a crosslinking agent, etc. are added to a substantially cylindrical mold and heated to foam the polyolefin resin and to form a covalently crosslinked structure between the polyolefin resin molecules. . Synthetic resin foams in which a covalently crosslinked structure is formed between resin molecules are generally called crosslinked foams and have excellent elasticity. Next, the obtained substantially cylindrical synthetic resin foam is cut to a desired length, and a mounting hole 12 is formed in a substantially central portion in the longitudinal direction by a Thomson type or the like.

  The foaming ratio of the synthetic resin foam is preferably adjusted from 2 to 15 times from the viewpoint of providing flexibility and imparting bristle to the brush body 2. If the expansion ratio is less than 2 times, it is too hard and the flexibility is impaired, and it becomes difficult to overlap the brush piece 3. It becomes difficult to give. In order to have more excellent flexibility and fur waist, it is desirable to adjust by 5 to 10 times.

  The foaming agent is not particularly limited as long as it is conventionally used for the production of synthetic resin foams. For example, sodium bicarbonate, ammonium bicarbonate, azodicarbonamide, benzenesulfonyl hydrazide, diester Pyrolytic foaming agents such as nitrosopentamethylenetetramine, toluenesulfonyl hydrazide, 4,4-oxybisbenzenesulfonyl hydrazide are preferably used, and the above materials may be used alone or in combination.

  The cross-linking agent is not particularly limited as long as it is conventionally used for production for the purpose of imparting elasticity to the synthetic resin foam. For example, dicumyl peroxide, 2,5-dimethyl Organic peroxides such as -2,5-bis-tertiary butyl peroxyhexene and 1,3-bis-tertiary peroxy isopropyl benzene are preferably used, and the materials may be used alone or in combination. There is no problem.

  In FIG. 2C, the brush body 2 is provided with a reinforcing member 4 having a substantially cylindrical hollow portion 13 in one space portion 31 of the brush piece 3 having an approximately M-shaped cross section. 11 and the attachment hole 12 of the reinforcing member 4 are inserted and formed so as to overlap each other.

  Then, as shown in FIG. 2 (d), the brush body 2 is folded in half at a substantially central portion in the longitudinal direction so that the reinforcing material 4 inserted into one space portion 31 of the brush piece 3 is outward. As shown in FIG. 1 (b), the brush body 2 is inserted into the groove 6 of the shaft body 5, and the rivets 10 are inserted into the overlapping mounting holes 11 and 12 and fixed to the shaft body 5, thereby being used for a car wash machine. The cleaning brush 1 is manufactured. Moreover, you may fold the brush body 2 in half at the approximate center part of a longitudinal direction so that the reinforcing material 4 inserted in one space part 31 of the brush piece 3 may become inward. Furthermore, the form which inserted the reinforcement material 4 in both the space parts 31 of the brush piece 3, and folded the brush body 2 in the approximate center part of the longitudinal direction is also employable.

  In addition to the substantially cylindrical shape as described above, the reinforcing member 4 is provided with a mounting hole 22 penetrating toward the opposite side at a substantially central portion in the longitudinal direction as shown in FIG. A generally drum-shaped reinforcing member 14 having a portion 23 can also be employed. When the substantially drum-shaped reinforcing material 14 is used, when the brush body 2 is folded in half, the thickness of the bottom surface of the folded-up brush body 2 is thinner than when the substantially cylindrical reinforcing material 4 is used. Therefore, the brush body 2 can be easily fixed to the shaft body 5 by the rivet 10.

  Further, as shown in FIG. 3 (b), the reinforcing member 24 having a square hollow section in which a square hollow portion 33 is formed, and a square hollow section in which a substantially round hollow portion 43 is formed as shown in FIG. 3 (c). It is also possible to use the reinforcing members 24 and 34 having a modified hollow cross section such as the reinforcing member 34 having the above. When the hollow rod-shaped reinforcing members 4, 14, 24, 34 as described above are used, when the brush body 2 comes into contact with the vehicle body that is the surface to be cleaned, the impact from the vehicle body is caused by the hollow portions 13, 23, 33, Since 43 absorbs rapidly, fur can be given to the brush body 2 over a long period of time. Even if a solid rod-shaped reinforcing material made of a synthetic resin foam having closed cells is used, there is no problem as long as it can overlap with the brush piece 3 and can give the brush body 2 bristles. .

  Further, as shown in FIG. 3 (d), the brush body 2 may be given bristles using a reinforcing material 44 made of a flat synthetic resin plate such as vinyl chloride, polystyrene, or acrylic. The reinforcing member 44 has an attachment hole 42 formed at a substantially central portion in the longitudinal direction, and curved portions 41 formed at four corners. Since the curved portions 41 are formed at the four corners of the reinforcing member 44, when the brush body 2 is configured to overlap the lower brush piece 8, the brush body 2 continues to contact the vehicle body and receives an impact from the vehicle body. However, since the corner portion is not provided, the lower brush piece 8 can be prevented from being torn or torn. In addition to the synthetic resin plate, a thermoplastic elastomer sheet, a film-like resin composition, or the like may be employed as the reinforcing material.

  Next, the material of the upper brush piece 7 will be described with reference to FIG.

  In FIG. 4A, the upper brush piece 7 is formed of a double structure made of a non-woven fabric 15 having a raised portion 19 formed on one side and a porous polyurethane having extremely fine bubbles 17. . The material as described above is manufactured by the following procedure. First, a plurality of fibers 16 were accumulated in a flat plate shape to form a cloth-like body. After a plurality of the cloth-like bodies were overlapped, a special needle was pierced and entangled three-dimensionally. A nonwoven fabric 15 is formed. The manufacturing method as described above is generally called needle punching. Next, the nonwoven fabric 15 is impregnated in the polyurethane solution, thereby filling the nonwoven fabric 15 with the polyurethane solution. Next, the non-woven fabric 15 filled with the polyurethane solution is immersed in water and carbon dioxide is injected into the water to cause carbonic acid foaming, and the non-woven fabric 15 and the porous polyurethane having ultrafine bubbles 17 are formed. A double structure comprising the base 18 is obtained. Next, the raised portion 19 is formed by polishing one side of the double structure using polishing paper or the like. Polyester is used as the material of the fiber 16, but spandex or the like called nylon, polypropylene, or urethane elastic yarn can be used alone or in combination. The fiber 16 may be either a short fiber or a long fiber. Generally, a short fiber is a fiber having a yarn length of 50 mm or less, and a long fiber is a fiber having a yarn length greater than 50 mm. The fiber 16 may be either a raw fiber or an ultrafine fiber. In general, the original yarn fiber is a fiber having a fineness of 1 dtex or more, the ultrafine fiber is a fiber having a fineness of less than 1 dtex, and 1 dtex is a fiber having a yarn length of 10,000 m and 1 g. That's it. Further, the double structure may be subjected to water repellent processing by using a method such as impregnation, immersion, spraying, or the like with a fluororesin or a urethane resin.

  When the above double structure is used for the upper brush piece 7, the upper brush piece 7 has porous polyurethane, so that it has excellent flexibility and evenly adheres to the vehicle body that is the surface to be cleaned, and is also non-woven fabric. 15 efficiently and reliably removes dirt. Further, when the raised portion 19 is in contact with the vehicle body, the coefficient of friction is improved compared to the case where the non-raised surface is in contact with the vehicle body, and the brushed portion 19 is more closely attached to the vehicle body. It is possible to scrape dirt accumulated on the uneven part.

  Moreover, the upper brush piece 7 can also use the flat nonwoven fabric 25 which consists of the some aggregate | assembly 20 like FIG.4 (b). As shown in FIGS. 4C and 4D, the assembly 20 is formed in a substantially wedge shape having a plurality of slits 27 in the longitudinal direction of the outer peripheral surface and a plurality of corners 28. It is. The nonwoven fabric 25 is manufactured in the following procedure. First, a synthetic resin such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyamide 6, polyamide 66, polyethylene, and polypropylene is melt-spun to obtain a raw yarn long fiber having a substantially round cross section. The obtained raw filament yarn is entangled three-dimensionally by needle punching to form a web that becomes a cloth-like body. Next, a high-pressure water stream of about 100 kg to 150 kg is applied to the web to bind the raw yarn long fibers, and the raw yarn long fibers are subjected to the high-pressure water flow, so that FIG. 6 (c) and FIG. ), A plurality of slits 27 are generated and subdivided along the longitudinal direction of the outer peripheral surface, and a plurality of subdivided ultrafine fibers 26 having corners 28 are formed. Next, a polymer elastic body 29 such as polyurethane is attached to the surface of the fiber 26 by using a method such as spraying, dipping, or impregnation to form a flat nonwoven fabric 25 composed of the aggregate 20 in which the elastic fibers 21 are converged. . The manufacturing method as described above is generally called a hydroentanglement method. In addition, the non-woven fabric 25 may be subjected to water repellent processing by using a method such as impregnation, immersion, spraying, or the like with a fluororesin or a urethane resin.

  When the non-woven fabric 25 is used for the upper brush piece 7, the non-woven fabric 25 has a polymer elastic body 29, so that it flexibly comes into contact with the vehicle body that is the surface to be cleaned and the corners 28 of the fibers 26 scrape dirt. Remove to take.

  In addition to the materials described above, the material used for the upper brush piece 7 located in the vicinity of the cleaning side is excellent in adhesion to the vehicle body and has high flexibility, woven fabric, knitted fabric, film-like resin A composition or the like can be used.

  Next, the material used for the lower brush piece 8 will be described.

  Since the lower brush piece 8 is located on the shaft body 5 side, it is preferable to use a material that has low water absorption and does not cause scratches even when contacting the vehicle body. For example, foamed polyolefin resin such as ethylene vinyl acetate, ethylene methyl acrylate, ethylene ethyl acrylate, ethylene butyl acrylate, ultra-low density polyethylene, low density polyethylene, polypropylene, etc., and a flat synthetic resin foam having countless closed cells Are preferably used.

  The synthetic resin foam is manufactured by the following procedure. First, a polyolefin resin, a foaming agent, a crosslinking agent, etc. are added to a mold having a legislative shape and heated to foam the polyolefin resin and form a covalently crosslinked structure between the molecules of the polyolefin resin. Synthetic resin foams in which a covalently crosslinked structure is formed between resin molecules are generally called crosslinked foams and have excellent elasticity. Next, the obtained synthetic resin foam having a legitimate shape is sliced to a desired thickness to form a flat synthetic resin foam.

  The synthetic resin foam used for the lower brush piece has a thickness of 1.5 to 3 mm and an expansion ratio of 8 to 12 times. Since the synthetic resin foam has closed cells, its water absorption is low and hardly absorbs water even during car washing. Further, since the expansion ratio is set at 8 to 12, it is flexible and does not cause any damage even if it contacts the vehicle body.

  In addition, about the material used for the lower brush piece 8, a thermoplastic elastomer sheet etc. can be used besides the above materials.

  The operation and action of the washing brush 1 for a car wash machine configured as described above are as follows.

  The washing brush 1 for a car wash machine has a brush body 2 having a brush piece 3 and a reinforcing material 4 and a shaft body 5, and the brush body 2 is formed on the outer periphery of the shaft body 5, and the brush piece 3 is an upper part. The brush piece 7 and the lower brush piece 8 are joined via a joint portion 9, the upper brush piece 7 is formed in the vicinity of the cleaning side, and the lower brush piece 8 is formed on the shaft body 5 side. Since the reinforcing material 4 is formed so as to overlap the piece 3, even if the brush piece 3, especially the upper brush piece 7 located in the vicinity of the washing side absorbs water during the car wash, the brush piece 3 Since the reinforcing material 4 is superposed on the brush body 2, the bristles of the brush body 2 are strongly held, and the brush body 2 does not wrap around the shaft body during rotation and the working radius does not decrease, and the brush body 2 rotates stably. For a long period of time and continuously contact the surface to be cleaned. It is possible. Therefore, since the washing brush 1 for a car wash machine can set the bristles of the brush body 2 strongly and can come into contact with the vehicle body, there is no generation of unwashed and a high washing effect is exhibited over a long period of time. be able to.

  Even if the upper brush piece 7 is made of expensive non-woven fabric 25 or a double structure made of porous polyurethane having non-woven fabric 15 and extremely fine bubbles 17, the lower brush piece 8 is inexpensive. Since a synthetic resin foam, a thermoplastic elastomer sheet, or the like is used and the brush piece 3 is formed via the joint portion 9, the production cost of the washing brush 1 for a car wash machine can be reduced.

  Next, the brush body 52 in another embodiment is demonstrated using FIG.

  5 (a) and 5 (b), the brush body 52 has an upper brush piece as opposed to a brush piece 53 in which a flat upper brush piece 57 and a lower brush piece 58 are integrated via a joint 59. A reinforcing material 54 made of a flat synthetic resin foam, a synthetic resin plate, a thermoplastic elastomer sheet or the like is sandwiched between 57 and the lower brush piece 58.

  The brush body 52 is manufactured by superimposing the reinforcing material 54 on the end of the lower brush piece 58, and further superposing one end of the upper brush piece 57, and sewing the joint 59 in a generally square shape. The

  Since the brush body 52 is formed by sandwiching the reinforcing material 54 between the joint portions 59 of the upper brush piece 57 and the lower brush piece 58, the upper brush piece 57 can be used even if water is absorbed during the car wash. Since the bristles are held by 54 and the upper brush pieces 57 adjacent to each other are prevented from sticking with water, a large contact area is ensured when the upper brush pieces 57 come into contact with the vehicle body. Therefore, the washing brush 1 for a car wash machine can remove the dirt adhering to the vehicle body quickly and reliably, so that the washing effect is greatly improved.

  Further, the four corners of the flat reinforcing member 54 may be formed in a curved shape. When the four corners of the reinforcing member 54 are formed in a curved shape, the reinforcing member 54 does not have corners at the four corners even when the brush body 52 continues to contact the vehicle body and receives an impact from the vehicle body. Therefore, the thread breakage of the joint portion 59 due to sewing can be prevented, and the upper brush piece 57 and the lower brush piece 58 can be prevented from being torn or torn.

  Further, the reinforcing material 54 may be overlapped on the joint portion 59 of the upper brush piece 57 and joined by sewing or the like without sandwiching the reinforcing material 54 between the upper brush piece 57 and the lower brush piece 58. Alternatively, the reinforcing material 54 may be overlapped under the joint portion 59 of the lower brush piece 58 and joined by sewing or the like. Furthermore, a form in which the reinforcing material 54 is overlaid on the joint portion 59 of the upper brush piece 57 and the reinforcing material 54 is overlaid under the joint portion 59 of the lower brush piece 58 and joined by sewing or the like can be employed. When the configuration as described above is adopted, workability can be simplified.

  Next, brush pieces 63, 73, and 83 according to other embodiments will be described with reference to FIG.

  In FIG. 6A, the brush piece 63 is an upper brush in which a plurality of divided pieces 61 are formed at the cleaning side end of the upper brush piece 67 by a slit 60 having an inclination angle θ with respect to the edge of the upper brush piece 67. The piece 67 and the lower brush 68 are formed through a joint 69 by sewing. In FIG. 6B, the brush piece 73 includes a joint portion 79 formed by sewing an upper brush piece 77 having a subdivided portion 76 formed by a subdividing machine or the like at an end portion on the cleaning side and a lower brush piece 78. It is formed through. In FIG. 6C, a brush piece 83 includes a subdividing portion 86 formed by a subdividing machine or the like at the cleaning side end, and an upper brush piece 87 having a plurality of divided pieces 81 formed by slits 80. The lower brush piece 88 is formed through a joining portion 89 by sewing.

  When the brush pieces 63, 73, 83 as described above are used, the washing brush 1 for a car wash machine is divided into fine pieces of the vehicle body by the divided pieces 61, 81 divided by the slits 60, 80 and the fine divided portions 76, 86. Since the divided pieces 61 and 81 and the fine divided portions 76 and 86 also come into contact with the uneven portions to scrape off the dirt, the cleaning performance is greatly improved. Further, in the case where a plurality of divided pieces 61 are formed by slits 60 having an inclination angle θ with respect to the edge of the upper brush piece 67 as in the brush piece 63, the divided pieces 61 have a cleaning locus inclined with respect to the vehicle body. Since the contact is made while drawing, it is possible to prevent the occurrence of streaky washing residue.
