Description

  The present invention relates to a washing brush for a car wash machine used in a car wash machine for washing dirt or the like adhering to a surface to be washed of an automobile or a vehicle, and a car wash machine equipped with the washing brush for the car wash machine. .

  Various improvements have been made to cleaning brushes used in car wash machines for washing dirt or the like adhering to the surface to be cleaned of automobiles or vehicles, and car wash machines equipped with the wash brushes, depending on the purpose of use. For example, the brush piece has a nonwoven fabric piece extending from the attachment base portion fixed to the rotating body to the tip portion, and a foamed synthetic resin piece superimposed on the back surface extending from the attachment base portion to the middle portion of the nonwoven fabric piece. There is a car wash brush (Patent Document 1) characterized by this.

  The above brush for car washing has a waist of the brush piece strongly set by the foamed synthetic resin piece superimposed on the back surface extending from the attachment base portion to the middle portion of the nonwoven fabric piece, and the brush piece is applied to the surface to be washed as the rotating body rotates. Can be brought into contact with each other by surface contact. And the stain | pollution | contamination of a to-be-cleaned surface is wiped off with the nonwoven fabric piece of the free end part which comprises a brush piece.

  However, although the brush piece comes into surface contact with the surface to be cleaned, the non-woven fabric piece is momentarily struck against the surface to be cleaned as the rotating body rotates, and only touches the dirty surface. The contact pressure when contacting the surface to be cleaned is extremely low, and dirt such as dust and sand on the surface to be cleaned is removed, but dirt and dirt that adheres firmly to the surface to be cleaned is removed. It was very difficult to do.

  By the way, the dirt adhering to the surface to be cleaned of the body of an automobile or the like is a mixture of components such as dust, sand dust, smoke, pitch, tar, iron powder, scale, etc. Some components are only on the surface of the surface to be cleaned, such as dust and sand dust, and others are components that are firmly attached to the surface to be cleaned, such as water stains. In particular, scale dirt is applied to the surface of the vehicle body and forms a three-dimensional network structure on the vehicle body, and adheres firmly to the mesh portion of hydrophobic components such as wax and coating agent. Impurities such as rainwater are taken in, and the wax and coating agent components that have taken in the impurities are dissolved by the heat of the vehicle body. Therefore, scale dirt is a component of dirt that is very difficult to remove even if the brush pieces of the car wash brush are brought into contact with each other as the rotor rotates.

  In order to remove scale dirt as described above, scale remover spraying and brushing process in which scale remover is sprayed on the vehicle surface with a scale remover spraying apparatus and brushed with a rotating brush apparatus, and rinse water is sprayed with a rinse water spraying device. Removing the scale of the vehicle by the car wash machine, wherein the rinsing process, the drying process in which the air is sprayed by the drying apparatus, and the wax process in which the wax is sprayed by the wax coating apparatus are performed while the traveling frame is traveling in the above order. A method (Patent Document 2) has been devised.

  In the method for removing scale from a vehicle by the car wash machine of Patent Document 2, a scale obtained by adjusting a strong alkaline substance having a pH of 14 to about pH 12 to 14 is used as a scale remover, and the scale dirt is lifted from the surface of the vehicle. Peel off. The mechanism as described above is to chemically change hydrophobic scale dirt to hydrophilic fatty acid soap by contacting and chemically reacting scale dirt which is a hydrophobic component and strong alkaline scale remover. This is a chemical removal method for removing scale dirt from the vehicle surface.

  In the chemical removal method as described above, the scale remover does not penetrate into the hydrophobic scale dirt unless the penetrating power of the hydrophilic strong alkaline scale remover is increased. It is necessary to add a surfactant having a high penetrating power. The descaling agent having enhanced penetrating power penetrates into the dirt of the scale and peels off the dirt of the scale through the chemical reaction as described above, but also penetrates into the paint of the vehicle by brushing with the rotating brush device. The descaling agent that has permeated the painted surface remains as a stain on the painted surface as the vehicle dries, and has a problem of deteriorating the appearance of the vehicle.

FIG. 3 (c) and FIG. 3 (d) are side views of the brush piece, and FIG. 4 (a) is a cleaning brush for a car wash machine according to the first embodiment of the present invention. Sectional drawing which shows the mode at the time of washing | cleaning a vehicle body with the attached car wash machine, FIG.4 (b) is a fragmentary sectional view which shows the use condition at the time of car wash of the washing brush for car wash machines in 1st Example of this invention. is there.

  1 (a) and 1 (b), a washing brush 1 for a car wash machine has a brush portion 2 in which a rivet 8 is inserted into a brush piece 4 formed in a loop shape, and a metallic material such as aluminum or iron. It is formed by being inserted into groove portions 9 provided at four locations on the outer periphery of the substantially cylindrical shaft body 3 and fixed to the shaft body 3 with rivets 8. The brush piece 4 has a flat plate-like cleaning member 5, a protective member 7, and a reinforcing member 6 which are overlapped and formed in a loop shape. The brush piece 4 is outward so that one surface of the cleaning member 5 contacts the surface to be cleaned. The other surface of the cleaning member 5 is overlapped with one surface of the protection member 7, and the other surface of the protection member 7 is overlapped with one surface of the reinforcing member 6. The hole 10 of the brush piece 4 formed in a loop shape is formed in parallel to the longitudinal direction of the shaft body 3. In addition, the groove part 9 provided in the outer peripheral surface of the shaft body 3 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, the cleaning member 5, the protection member 7, and the reinforcing member 6 constituting the brush piece 4 will be described in detail.

  2 (a) and 2 (d), the cleaning member 5 includes an ultrafine fiber 14 constituting one side of the non-woven fabric 11, with one side of the flat non-woven fabric 11 being superimposed on both sides of the flat knitted fabric 12. In addition, the nonwoven fabric 11 and the knitted fabric 12 are intertwined by entanglement of the single fibers 19 constituting the knitted fabric 12, and the polymer elastic body 15 is attached to the surface of the ultrafine fibers 14 and the single fibers 19. It consists of a leather-like base material 29 in which the nonwoven fabric 11 and the knitted fabric 12 are integrated by adhering the single fiber 19 via the polymer elastic body 15. Note that polyurethane is used as the material of the polymer elastic body 15. The cleaning member 5 is formed with a plurality of mounting holes 20 into which the rivets 8 are inserted by a Thomson type, a cutter or the like.

  The thickness of the cleaning member 5 is preferably 0.5 mm or more and 4.0 mm or less, and when the thickness is less than 0.5 mm, it is easy to wear when it repeatedly comes into contact with the surface to be cleaned, and is inferior in durability, and the thickness exceeds 4.0 mm. In such a case, a liquid such as washing water becomes heavier during the car wash, the load on the drive source of the car wash machine increases, and the rotation of the car wash machine washing brush 1 becomes unstable. The cleaning member 5 can also employ a form in which one surface of the flat nonwoven fabric 11 is superimposed on one surface of the flat knitted fabric 12.

  In FIG. 2B, a plurality of ultrafine fibers 14 having a substantially round cross-section constituting the nonwoven fabric 11 are gathered, and a polymer elastic body 15 having ultrafine bubbles 16 is attached to the surface of each ultrafine fiber 14. By doing so, the converging body 13 is formed. The converging body 13 is formed with a concave portion 17 and a convex portion 18 that are formed between adjacent microfibers 14. In addition, as a material of the ultrafine fibers 14, synthetic fibers such as polyester and nylon are used, and the fineness is less than 1 dtex. The fineness of 1 dtex is a fiber that becomes 1 g at a yarn length of 10,000 m. Further, the cross-sectional shape of the ultrafine fiber 14 may be an irregular cross-section such as a triangle or a quadrangle other than the substantially round shape. Further, the ultrafine fiber 14 may be either a short fiber having a yarn length of 50 mm or less, or a long fiber having a yarn length exceeding 50 mm.

  In FIG.2 (c), the polymer elastic body 15 which has the ultrafine bubble 16 has adhered to the surface of the single fiber 19 which has the substantially round cross-section which comprises the knitted fabric 12. FIG. As a material of the single fiber 19, synthetic fiber such as polyester or nylon is used, and the fineness is 1 dtex or more. Moreover, the cross-sectional shape of the single fiber 19 may be an irregular cross section such as a triangle or a quadrangle other than the substantially round shape.

  The leather-like base material 29 used for the cleaning member 5 is manufactured by the following procedure. First, a flat knitted fabric 12 in which the single fibers 19 are formed by flat knitting, rubber knitting, pearl knitting, denby knitting, atlas knitting, cord knitting or the like is prepared. Next, the flat nonwoven fabric 11 which consists of a composite fiber which has water-soluble thermoplastic polyvinyl alcohol-type polymer on both surfaces of the knitted fabric 12, and crystalline thermoplastic polymer whose melting | fusing point is higher than the said water-soluble thermoplastic polyvinyl alcohol-type polymer. The composite fibers and the single fibers 19 are entangled and the nonwoven fabric 11 and the knitted fabric 12 are entangled to form a cloth-like body by piercing a special needle generally called needle punching. In addition to the needle punching, the composite fiber and the single fiber 19 can be entangled by high-pressure water flow, and the nonwoven fabric 11 and the knitted fabric 12 can be entangled to form a cloth-like body. The crystalline thermoplastic polymer having a higher melting point than the water-soluble thermoplastic polyvinyl alcohol polymer is a resin such as polyester or nylon. Next, the cloth-like body is dipped in hot water, the water-soluble thermoplastic polyvinyl alcohol polymer is extracted and removed, and the nonwoven fabric 11 layer is formed with the ultrafine fibers 14, and the polymer elastic body 15 is placed in the polyurethane solution. It is immersed and polyurethane is adhered to the surfaces of the ultrafine fibers 14 and the single fibers 19. At that time, a plurality of ultrafine fibers 14 are gathered and formed on the converging body 13. Next, by immersing the cloth impregnated with polyurethane in water and injecting carbon dioxide, the polyurethane is foamed, ultrafine bubbles 16 are formed, and the water is volatilized by heating. A flat leather-like base material 29 is produced. Instead of the knitted fabric 12, a flat woven fabric in which the single fibers 19 are formed of plain weave, twill weave, satin weave, or the like can also be used.

  In FIG. 3A, the protective member 7 is composed of a flat synthetic resin foam 21 having a plurality of closed cells 22. A plurality of mounting holes 23 into which the rivets 8 are inserted are formed in the protective member 7 by a Thomson type, a cutter or the like. The thickness of the protective member 7 is preferably not less than 0.5 mm and not more than 5.0 mm. When the thickness is less than 0.5 mm, the pressure on the cleaning member 5 is low and the cleaning performance of the brush piece 4 is low, and the thickness is 5.0 mm. When exceeding, it will become difficult to form the brush piece 4 in a loop shape.

  The synthetic resin foam 21 used for the protective member 7 is manufactured by the following procedure. First, in a rectangular parallelepiped mold, pellet-form or powder-form polyethylene, ethylene vinyl acetate, ethylene methyl acrylate, ethylene ethyl acrylate, ethylene butyl acrylate and other polyolefin-based synthetic resins, and additives such as foaming agents and crosslinking agents By mixing and heating, the synthetic resin is foamed and a covalently crosslinked structure is formed between the molecules of the synthetic resin. A foam in which a covalent cross-linked structure is formed between molecules of a synthetic resin is generally called a cross-linked foam, and since a bridge structure is formed between the molecules, it has excellent elasticity. . Next, the obtained cubic foam is sliced to a desired thickness to form a flat synthetic resin foam 21.

  The foaming ratio of the synthetic resin foam 21 is preferably 5 to 30 times. When the foaming ratio is less than 5 times, it is hard to form the brush piece 4 in a loop shape, and the foaming ratio is 30 times. When exceeding, the press against the cleaning member 5 is soft and the cleaning performance of the brush piece 4 is inferior.

  In FIG. 3B, the reinforcing member 6 is composed of a flat synthetic resin plate 24. A plurality of mounting holes 26 into which the rivets 8 are inserted are formed in the reinforcing member 6 by a Thomson type, a cutter or the like, and curved portions 25 are formed at four corners. Since the curved portions 25 are formed at the four corners of the reinforcing member 6, when the loop-shaped brush piece 4 is configured so as to be superimposed on the protective member 7, the brush piece 4 continues to abut on the surface to be cleaned. Even if an impact is received from the surface, the protective member is prevented from being broken or torn because it does not have a corner. The thickness of the reinforcing member 6 is preferably 0.1 mm or more and 1.0 mm or less, and when the thickness is less than 0.1 mm, the pressure on the cleaning member 5 is soft and the cleaning performance of the brush piece 4 is low. When it exceeds 0 mm, it is hard and it becomes difficult to form the brush piece 4 in a loop shape.

  As a material of the synthetic resin plate 24, a thermoplastic resin such as polyethylene, polystyrene, acrylic resin, vinyl chloride resin or the like is employed. Further, since the synthetic resin plate 24 in which the covalent cross-linking structure is formed between the molecules of the synthetic resin has the bridging structure formed between the molecules, the synthetic resin plate 24 has excellent elasticity and the configuration of the loop-shaped brush piece 4. When formed as a part, the brush piece 4 continues to contact the surface to be cleaned, and even if it receives an impact from the surface to be cleaned, it does not easily break or crack, leading to improved durability of the brush piece 4. In addition to the synthetic resin plate 24, the reinforcing member 6 may be a flat thermoplastic elastomer sheet, a film-like resin composition, or the like.

  Next, the manufacturing method of the washing brush 1 for car wash machines is demonstrated.

  First, as shown in FIG. 2 (a), FIG. 3 (a), and FIG. 3 (b), the plate is cut into a desired length and width, and the mounting holes 20, 23, and 26 are formed. A cleaning member 5, a protective member 7, and a reinforcing member 6 are prepared. Next, as shown in FIG. 3 (c), the cleaning member 5, the protective member 7 having a plurality of closed cells 22 and the reinforcing member 6 are overlapped, and the brush piece 4 is bent in the direction of the arrow. As shown in the figure, the cleaning member 5 has a hole 10, one surface of the cleaning member 5 is located outward, the other surface of the cleaning member 5 is overlapped with one surface of the protection member 7, and the other surface of the protection member 7. Forms a loop-like brush piece 4 superimposed on one surface of the reinforcing member 6. When the brush piece 4 is formed in a loop shape, the mounting hole 20 of the cleaning member 5, the mounting hole 23 of the protective member 7, and the mounting hole 26 of the reinforcing member 6 are overlapped so that they substantially coincide with each other. .

  Then, the rivet 8 is inserted into the mounting holes 20, 23, 26 of the brush piece 4 to constitute the brush portion 2, and the brush portion 2 is inserted into the groove portions 9 provided at four locations on the outer periphery of the shaft body 3. By fixing the rivet 8 to the shaft body 3 by a riveter or the like, the washing brush 1 for a car wash machine as shown in FIGS. 1 (a) and 1 (b) is manufactured.

  Next, operation | movement and an effect | action of the washing brush 1 for car wash machines are demonstrated using Fig.4 (a) and FIG.4 (b).

  In FIG. 4A, the washing brush 1 for a car wash machine is attached to the car wash machine, rotated by a drive source (not shown), and pressed the brush piece 4 against the surface of the vehicle body 27, which is the surface to be cleaned, from the front to the rear. Or move from the rear to the front. As shown in FIG. 4A, the brush piece 4 moves while being easily deformed along the shape and irregularities of the surface of the vehicle body 27. Needless to say, during this time, it is needless to say that liquid such as cleaning water or cleaning agent is sprayed from the car wash machine to the vehicle body 27 and / or the car wash machine cleaning brush 1. 4A is a top brush that cleans the hood, front window, roof, rear window, trunk, and the like of the vehicle body 27. As shown in FIG.

  Then, as shown in FIG. 4B, when the washing brush 1 for a car washer is rotated in the direction of arrow B and the brush piece 4 is pressed against the vehicle body 27, the hole portion 10 of the loop-like brush piece 4 is Since it is formed in parallel with the longitudinal direction of the shaft body 3, the brush piece 4 comes into contact with the vehicle body 27 by surface contact as the shaft body 3 rotates. Further, the cleaning member 5 constituting the brush piece 4 is in close contact with the vehicle body 27 while being pressed by the reinforcing member 6 and the protective member 7, and is in contact with the nip width W. Therefore, the brush piece 4 applies surface pressure to the vehicle body 27 by surface contact, and the cleaning member 5 comes into contact with the vehicle body 27 in close contact with the vehicle body 27. The piece 4 is removed as a film layer on the vehicle body 27 and is securely removed while rubbing off the dirt dirt 28 and the like firmly adhered, and the vehicle body 27 is washed.

  The cleaning member 5 is flexible because the polymer elastic body 15 having the foamed ultrafine bubbles 16 adheres to the surfaces of the ultrafine fibers 14 constituting the nonwoven fabric 11 and the single fibers 19 constituting the knitted fabric 12. Even if it is in contact with the vehicle body 27 while surface pressure is applied, the vehicle body 27 is not damaged. Further, the ultrafine fibers 14 constituting the nonwoven fabric 11 are a converging body 13 in which a plurality of fibers are gathered, and are firmly attached to the vehicle body 27 by the concave portions 17 and the convex portions 18 formed between the adjacent ultrafine fibers 14. Scale dirt 28 and the like are scraped off. Furthermore, since the nonwoven fabric 11 and the knitted fabric 12 are intertwined and integrated in the cleaning member 5, even if it repeatedly comes into contact with the vehicle body 27, the knitted fabric 12 suppresses the elongation of the nonwoven fabric 11, so that it is cut, torn, etc. Is highly durable. Even if the cleaning member 5 is damaged, the protective member 7 made of the synthetic resin foam 21 excellent in flexibility comes into contact with the vehicle body 27, and the reinforcing member 6 made of the hard synthetic resin plate 24 is attached to the vehicle body 27. Since it does not contact, the vehicle body 27 is not damaged.

  Next, the cleaning performance of the cleaning brush 1 for a car wash machine of the present invention was tested. The measurement was performed as shown below, and the results are shown in Table 1.

  As an example, a cleaning member 5 made of a leather base material 29 having a thickness of 1.2 mm, a length of 300 mm, and a width of 50 mm, a synthetic resin foam 21 having a thickness of 2.5 mm, a length of 300 mm, and a width of 50 mm 16 protective members 7 each made of a synthetic resin plate 24 having a thickness of 0.5 mm, a length of 300 mm, and a width of 50 mm were prepared. Next, the cleaning member 5, the protection member 7, and the reinforcing member 6 are overlaid, bent, and have a hole 10, one surface of the cleaning member 5 is located outward, and the other surface of the cleaning member 5 is The protection member 7 is overlapped with one surface, and the other surface of the protection member 7 forms a loop-shaped brush piece 4 that is overlapped with one surface of the reinforcing member 6. , 26 to insert the rivet 8 to form the brush portion 2. Next, the brush portion 2 is inserted into the groove portions 9 provided at four locations on the outer periphery of the substantially cylindrical shaft body 3 made of iron having a diameter of 114 mm and a length of 360 mm, and the rivet 8 is inserted into the shaft body 3. Fixed to. By forming four brush portions 2 in one groove portion 9, one washing brush 1 for a car wash machine for testing of the example was manufactured.

  As a comparative example, a cleaning member 5 made of a leather-like base material 29 having a thickness of 1.2 mm, a length of 300 mm, and a width of 50 mm, a synthetic resin foam 21 having a thickness of 2.5 mm, a length of 220 mm, and a width of 50 mm 16 protective members 7 each made of a synthetic resin plate 24 having a thickness of 0.5 mm, a length of 220 mm, and a width of 50 mm were prepared. In addition, two attachment holes were provided in the substantially central portion in the longitudinal direction of the cleaning member 5, the protective member 7, and the reinforcing member 6, respectively. Next, the cleaning member 5, the protection member 7, and the reinforcing member 6 are overlapped so that the mounting holes are substantially coincident with each other, and are folded in half at a substantially central portion in the longitudinal direction to form a brush piece. Was inserted to form a brush portion. Next, the brush portion was inserted into the groove portions provided at four locations on the outer periphery of the substantially cylindrical shaft body made of iron having a diameter of 114 mm and a length of 360 mm, and the rivet was fixed to the shaft body. By forming four brush portions in one groove portion, one cleaning brush for a car wash machine for testing of a comparative example was manufactured.
