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, in a rotating brush for a car wash machine in which brush elements are implanted around the rotating shaft, the density of the brush elements is dense on the inner side in the radial direction with respect to the rotating shaft, and is implanted on the outer side. A rotating brush for car wash machines (Patent Document 1) is devised in which the state is repeated in the circumferential direction of the rotating shaft.

  In the cleaning brush for cleaning dirt and the like adhering to the surface to be cleaned, the cleaning brush is formed of a pedestal, a channel brush, and a metal fitting, and the channel brush includes a brush piece, a core wire, and a belt-like body. The brush piece is formed of a long film-shaped resin composition and a flat synthetic resin foam, and the long film-shaped resin composition and the flat plate-shaped resin composition.

There is a cleaning brush characterized in that (Patent Document 2).

JP 2002-160611 A JP 2005-305072 A

  The rotating brush for a car wash machine of Patent Document 1 is configured such that the density of the brush element is dense on the inner side in the radial direction with respect to the rotation axis and rough on the outer side, so that the brush element is given a fluff. In addition, it is possible to provide a rotating brush with good car washability without leaving unwashed parts in the recesses of the vehicle body. However, since the brush elements are all made of a material having substantially the same rigidity, if the rigidity of the material is increased, the fluff will be stronger, but it will be easier to attach scratches to the vehicle body. Further, if the rigidity of the material is lowered, scratches on the vehicle body are difficult to adhere, but there is a problem that the fluff is weak and the cleaning performance of the rotating brush for a car wash machine is inferior.

  The cleaning brush of Patent Document 2 is formed by laminating a flat synthetic resin foam on a long film-shaped resin composition, and the film-shaped resin composition is formed so as to contact the surface to be cleaned. Synthetic resin foam that gives excellent elasticity to the film-like resin composition, and because the film-like resin composition can strongly set the elasticity and abut against the surface to be cleaned, it exhibits excellent cleaning performance can do. However, the film is generally a resin composition having a thickness of less than 0.5 mm, and since the thickness is small, the impact resistance is extremely weak, and the film-like resin composition repeatedly contacts the surface to be cleaned. If it continues, tearing, breaking, cutting, tearing, etc. will occur. Therefore, there has been a problem that the durability of the cleaning brush is extremely low.

  In addition, the synthetic resin foam has a problem that the cost of the cleaning brush is increased because the cost is higher than that of the film-shaped resin composition.

  The present invention solves the above-described conventional problems, and does not cause scratches on the surface to be cleaned, and a cleaning brush for a car wash machine that exhibits excellent cleaning performance over a long period of time without generation of washing residue, and The object is to provide a car washing machine equipped with the washing brush for the car washing machine at a low cost.

Example 1
1A is a front view of a washing brush for a car wash machine according to the first embodiment of the present invention, FIG. 1B is a cross-sectional view of the brush body, and FIG. 2A is a front view of the cleaning member. 2B is a cross-sectional view taken along the line AA of FIG. 2A, FIG. 2C is a perspective view of the reinforcing member as seen from the front side, and FIG. FIG. 2C is a cross-sectional view taken along the line BB of FIG. 2 and FIG. 3 is a perspective view of the shaft body to which the locking member constituting the washing brush for the car wash machine according to the first embodiment of the present invention is fixed viewed from the front side. FIG. 4 is a perspective view of the manufacturing state of the channel brush as seen from the front side.

  1 (a) and 1 (b), a washing brush 1 for a car wash machine has a brush piece 6 comprising a long washing member 7 and a reinforcing member 8 sandwiched between a core wire 10 and a belt-like body 11. At the same time, the brush body 4 formed by the long channel brush 5 formed by folding is a substantially cylindrical shape made of a metal material such as aluminum or iron, or a synthetic resin material such as vinyl chloride or polyacetal. The shaft 3 is wound around the outer periphery of the shaft 3 in a spiral shape, and covers both ends of the brush body 4 so that the locking tool 12 is covered, and both ends of the locking tool 12 are fixed to the shaft 3 with screws 13. The brush part 2 is comprised.

  The core wire 10 constituting the channel brush 5 has a substantially cylindrical shape having a substantially round cross section, and is made of a metal material such as aluminum or iron. Moreover, the strip | belt-shaped body 11 consists of metal materials, such as aluminum, iron, and stainless steel, in the elongate shape which has a substantially U-shaped cross section.

  In FIG. 1B, the brush piece 6 is formed in the channel brush 5 by laminating the long cleaning member 7 and the reinforcing member 8 and being sandwiched between the core wire 10 and the belt-like body 11. The superposed cleaning member 7 and the reinforcing member 8 are folded so as to have a substantially V-shaped cross section so that the cleaning member 7 faces outward. Accordingly, in the brush piece 6, the cleaning member 7 comes into contact with the surface to be cleaned as the shaft body 3 constituting the cleaning brush 1 for a car wash machine rotates. Further, the finely divided portions 9 are formed at both ends of the cleaning member 7, and the hair length of the cleaning member 7 is set to be larger than the hair length of the reinforcing member 8. Further, the reinforcing member 8 is set so as to be more rigid than the cleaning member 7.

  Next, the manufacturing method of the washing brush 1 for car wash machines will be described in detail.

  First, as shown in FIG. 2A, a cleaning member 7 made of a long synthetic resin fiber is prepared. 2 (a) and 2 (b), the cleaning member 7 has a long shape having a substantially corrugated cross section, and subdivided portions 9 are formed at both ends. Since the cleaning member 7 has a substantially corrugated cross section, a plurality of grooves 14 are formed on the surface. The thickness of the cleaning member 7 is set to about 0.5 to 3 mm, and the width is set to about 1 to 10 mm. When the thickness is less than 0.5 mm, the durability is poor, and when it exceeds 3 mm, the flexibility is impaired. When the width is less than 1 mm, the fluff is weak, and when it exceeds 10 mm, the flexibility is inferior. Moreover, although the width | variety and length of the bristle 15 per one formed in the subdivision part 9 depend on the width | variety and length of the cleaning member 7, a width | variety is about 0.05-0.5 mm, long The length is desirably set to about 10 to 50 mm. When the width is less than 0.05 mm, it is easy to cut and the durability is inferior, and when it exceeds 0.5 mm, the scraping performance of the dirt adhering to the fine irregularities of the surface to be cleaned is inferior. When the length is less than 10 mm, the dirt scraping performance is inferior, and when the length exceeds 50 mm, the fluff is extremely weak. In addition, the cross-sectional shape of the cleaning member 7 is not particularly limited, and may be a substantially round cross-section. For example, the cross-sectional cross-section, M-shaped cross-section, N-shaped cross-section, saddle-shaped cross-section, etc. It doesn't matter.

  The cleaning member 7 is made of an ultra-low density polyethylene, a low density polyethylene, a linear low density polyethylene, a medium density polyethylene, a high density polyethylene, a polypropylene-based thermoplastic resin, an ethylene-α olefin copolymer elastomer, ethylene A monofilament polymer-alloyed by blending a polyolefin-based thermoplastic elastomer such as an α-olefin cross-linked copolymer elastomer and a styrene / ethylene / block copolymer elastomer. The reason why the thermoplastic alloy is blended with the thermoplastic elastomer and polymer alloyed is to impart flexibility to the cleaning member. The weight blending ratio of the thermoplastic resin and the thermoplastic elastomer is desirably set to 1 to 10 parts by weight of the thermoplastic elastomer with respect to 100 parts by weight of the thermoplastic resin. When the thermoplastic elastomer is less than 1 part by weight, it is difficult to impart flexibility to the cleaning member 7, and when it exceeds 10 parts by weight, the fluff of the cleaning member 7 becomes weak and the durability is inferior. Become.

  One index indicating the rigidity of the cleaning member 7 is hardness, and the hardness is preferably set to 40 ° or more and less than 70 °. If the hardness is less than 40 °, it is too soft and is likely to wear when it comes into contact with the surface to be cleaned, and is inferior in durability. If it is 70 ° or more, it is too hard to easily cause scratches on the surface to be cleaned . In addition, hardness represents the hardness of a substance and is the hardness measured by the durometer hardness test described in the hardness test method of JISK6253 vulcanized rubber and thermoplastic rubber.

  The cleaning member 7 is manufactured by the following procedure. First, pelletized or powdered thermoplastic resin and thermoplastic elastomer are heated and melted at a temperature equal to or higher than the melting point. In that case, you may mix | blend additives, such as a ultraviolet absorber, a crosslinking agent, and a pigment, as needed. Next, spinning is performed through a generally corrugated die attached to the tip of the extruder. After extrusion, the filament is stretched in the longitudinal direction with a stretching machine while being heated, and after stretching, the monofilament is formed by cooling and solidifying in a step called annealing. The manufacturing method as described above is generally called extrusion molding. Next, the obtained monofilament is cut into a desired length, and a predetermined length at both ends of the monofilament is processed by a subdivision machine having a dividing blade and a cutter rotating at a predetermined rotation speed. The cleaning member 7 in which the subdivided portions 9 having the plurality of brush hairs 15 are formed at both ends is manufactured.

  The above-described method of stretching the monofilament in the longitudinal direction is called uniaxial stretching. Uniaxial stretching is a processing method in which stretching stress is applied only in one direction. In the direction parallel to the stretching direction, molecular orientation occurs, so the tensile strength is remarkably improved, but the direction perpendicular to the stretching direction is tensile strength. Therefore, it has a property that it is easy to tear in a direction parallel to the stretching direction. Therefore, the cleaning member 7 can form the finely divided portion 9. The molecular orientation means that linear molecules are arranged in a certain direction by the action of an external force in a molten or solid state.

  Next, as shown in FIG. 2C, a reinforcing member 8 made of a long synthetic resin fiber is prepared. 2 (c) and 2 (d), the reinforcing member 8 is formed in a long shape having a cross-shaped cross section. Since the reinforcing member 8 has a cruciform cross section, the wash water can be temporarily stored in the four corners 16, so that the water retention during the car wash is increased and the cleaning performance of the brush piece 6 is improved. It leads to improvement. Further, since the reinforcing member 8 has the core portion 17 at the center of the cross section, the rigidity is improved, and when the reinforcing member 8 is superimposed on the cleaning member 7 and formed on the brush piece 6, the cleaning member 7 is given a strong bristle waist. be able to. The width and height of the reinforcing member 8 are set to about 0.5 to 3 mm. When the width and height are less than 0.5 mm, the durability is poor, and when it exceeds 3 mm, the flexibility is impaired. In addition, the cross-sectional shape of the cleaning member 7 is not particularly limited, and may be a substantially round cross-section, for example, an irregular cross-sectional shape such as an M-shaped cross-section, an N-shaped cross-section, a saddle-shaped cross-section, or an approximate corrugated cross-section. It doesn't matter.

  The reinforcing member 8 is a monofilament made of a polyolefin-based thermoplastic resin such as ultra-low density polyethylene, low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, and polypropylene. A polyolefin-based thermoplastic resin has a water absorption rate of 0%, and the hair does not become weak due to water absorption. Further, the weight of the washing brush 1 for the car wash machine becomes heavy due to water absorption, so that the load on the drive source of the car wash machine does not increase, and a stable rotational drive is maintained for a long period of time. Further, due to water absorption, there is no problem of freezing of the brush piece 6 in winter, particularly in cold regions. Furthermore, polyolefin-based thermoplastic resins are inexpensive.

  One index indicating the rigidity of the reinforcing member 8 is hardness, and the hardness is preferably set to 70 ° or more and 90 ° or less. When the hardness is less than 70 °, it is too soft and it is difficult to impart strong bristle to the cleaning member 7, and when it exceeds 90 °, it is too hard and the brush piece 6 repeatedly contacts the surface to be cleaned. The hair breaks early and the durability is inferior. In addition, hardness represents the hardness of a substance and is the hardness measured by the durometer hardness test described in the hardness test method of JISK6253 vulcanized rubber and thermoplastic rubber.

  The reinforcing member 8 is manufactured by the following procedure. First, a pellet-like or powdery thermoplastic resin is heated and melted at a temperature equal to or higher than the melting point. In that case, you may mix | blend additives, such as a ultraviolet absorber, a crosslinking agent, and a pigment, as needed. Next, spinning is performed through a cross-shaped base attached to the tip of the extruder. After extrusion, the filament is stretched in the longitudinal direction with a stretching machine while being heated, and after stretching, the monofilament is formed by cooling and solidifying in a step called annealing. The manufacturing method as described above is generally called extrusion molding. Next, the obtained monofilament is cut into a desired length, and the reinforcing member 8 is manufactured. The hair length of the reinforcing member 8 is set to be equal to or less than the hair length of the cleaning member 7.

  Next, as shown in FIG. 3, a locking tool 12 having a plurality of claws 18 is fixed with screws 13 in the vicinity of both end portions of the outer peripheral portion of the substantially cylindrical shaft body 3. Then, as shown in FIG. 4, a plurality of cleaning members 7 and reinforcing members 8 are superimposed on a long band-like body 11 having a substantially U-shaped cross section. The central portion is installed on the base 19 so as to overlap the upper portion of the belt-like body 11. Note that the cleaning member 7 is positioned above the belt-like body 11 and the reinforcing member 8 is positioned above the cleaning member 7. Next, using the vertical roll 20, the brush piece 6 composed of the cleaning member 7 and the reinforcing member 8 overlapped with each other with the core wire 10 is sandwiched, and the core wire 10 is pushed into the inside of the substantially U-shaped band 11. . Next, the belt-like body 11 is caulked from both sides using the horizontal rolls 21 installed on both sides of the belt-like body 11. As a result, as shown in FIG. 1B, the substantially central portion of the long brush piece 6 configured to have the cleaning member 7 on the outside and the reinforcing member 8 on the inside becomes the core wire 10 and the belt-like body 11. A channel brush 5 that is sandwiched and folded is formed.

  And the brush piece 6 formed in one edge part of the brush body 4 which consists of channel brushes 5 is cut off, and the edge part of the said channel brush 5 is formed in the both sides of the one locking tool 12 shown in FIG. It is inserted between the claws 18 and fixed by folding the claws 18 inward. Next, while rotating the shaft body 3, the brush body 4 composed of a single long-shaped channel brush 5 is twisted around the outer periphery of the shaft body 3 to be spirally wound, and the channel The brush piece 6 formed on the other end portion of the brush 5 is cut out, and the other end portion of the brush body 4 is formed by the claw 18 formed on the other locking member 12 attached to the outer peripheral portion of the shaft body 3. A washing brush 1 for a car wash machine comprising a brush portion 2 to which is fixed is manufactured as shown in FIG. In addition, when inserting the edge part of the brush body 4 between the nail | claws 18 formed in the both sides of the locking tool 12, it does not cut out the brush piece 6 formed in the edge part of the brush body 4, but between nail | claws 18 A form to be inserted into is also adopted.

  In this embodiment, the cleaning member 7 and the reinforcing member 8 have different cross-sectional shapes. However, if the cleaning member 7 and the reinforcing member 8 have different rigidity, the cleaning member 7 and the reinforcing member 8 The cross-sectional shapes may be substantially the same. When the cross-sectional shapes of the cleaning member 7 and the reinforcing member 8 are substantially the same, it is possible to use a base having the same shape when melt spinning, and it is not necessary to prepare a plurality of different bases. Connected. The conditions such as the cross-sectional shape of the cleaning member 7 and the reinforcing member 8 and the polyolefin-based material used are appropriately determined depending on the usage environment, cost, and other conditions of the cleaning brush 1 for a car wash machine.

  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 rigidity lower than that of the reinforcing member 8 while the brush piece 6 is given a strong bristle by the reinforcing member 8 having a rigidity higher than that of the cleaning member 7 as the shaft body 3 rotates. The flexible cleaning member 7 contacts the surface to be cleaned. Therefore, the cleaning brush 1 for a car wash machine exhibits excellent cleaning performance without causing scratches on the surface to be cleaned.

  Further, since the finely divided portions 9 are formed at both ends of the cleaning member 7, the brush bristles 15 formed by the finely divided portions 9 scrape off the dirt adhering to the fine uneven portions of the surface to be cleaned, Remove. Therefore, the cleaning performance of the car brush washing brush 1 is greatly improved.

  Further, since the cleaning member 7 has a plurality of groove portions 14 formed in the longitudinal direction, since the cleaning water can be temporarily stored in the groove portions 14, water retention during car washing is increased. Therefore, the cleaning performance of the washing brush 1 for a car wash machine is dramatically improved.

  Further, since the cleaning member 7 and the reinforcing member 8 are made of synthetic resin fibers having excellent wear resistance, even if the brush piece 6 continues to contact the surface to be cleaned repeatedly, it is difficult to break, break, etc. The machine cleaning brush 1 has excellent durability.

  Furthermore, since the cleaning member 7 and the reinforcing member 8 are made of synthetic resin fibers having a low-cost polyolefin-based thermoplastic resin, the cleaning brush 1 for a car wash machine can be provided at a low cost.

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

  As Example 1, a plurality of long cleaning members 7 having a substantially corrugated cross section having a thickness of 0.6 mm, a width of 7 mm, and a length of 240 mm were prepared. At both ends of the cleaning member 7, subdivided portions 9 made of brush bristles 15 having a width of 0.05 mm and a length of 10 mm were formed. A plurality of long reinforcing members 8 having a cross-shaped cross section having a width of 1 mm, a height of 1 mm, and a length of 160 mm were prepared. Next, the brush member 6 is formed by superimposing the substantially central portions of the cleaning member 7 and the reinforcing member 8 in the longitudinal direction, and the brush member 6 is sandwiched between the core wire 10 made of aluminum and the strip 11, The brush body 4 including the channel brush 5 having the brush pieces 6 folded together was formed. The brush piece 6 was formed such that the cleaning member 7 was outward and the reinforcing member 8 was inward. Next, the brush piece 6 formed at one end of the channel brush 5 is cut off in the vicinity of the belt-like body 11 over the longitudinal direction of 50 mm of the channel brush 5 and has a diameter of 114 mm and a length of 360 mm. It was fixed in the vicinity of the end of the outer peripheral portion of the substantially cylindrical shaft body 3 made of iron by using a locking tool 12 attached with a screw 13. Then, the channel brush 5 is spirally wound around the outer periphery of the shaft body 3, and the brush piece 6 formed on the other end of the channel brush 5 is also strip-shaped over the longitudinal direction of the channel brush 5. Cut out in the vicinity of the body 11 and fixed with a locking tool 12 to produce one washing brush 1 for a test car wash machine. The cleaning member 7 was blended with 5 parts by weight of an ethylene-α-olefin copolymer elastomer to 100 parts by weight of low-density polyethylene and had a hardness of 65 °. On the other hand, the reinforcing member 8 was made of low-density polyethylene and had a hardness of 80 °. Moreover, the width | variety of the strip | belt-shaped body 11 was 5 mm, and it wound around the outer peripheral part of the shaft 3 helically, and set the space | interval of the adjacent strip | belt-shaped body 11 to 25 mm.

  As Comparative Example 1, the brush piece 6 is composed of only the cleaning member 7, the weight of the brush piece 6 is substantially the same as that of Example 1, and the cleaning member 7 is made of synthetic resin fiber having a substantially corrugated cross section made of low-density polyethylene. A single washing brush 1 for a car wash machine having the same conditions as the washing brush 1 for a car wash machine of Example 1 was prepared except that it was used. The hardness of the cleaning member 7 of Comparative Example 1 was 80 °.

  As Comparative Example 2, the brush piece 6 is composed only of the cleaning member 7, the weight of the brush piece 6 is substantially the same as that of Example 1, and the cleaning member 7 is 100 parts by weight of low density polyethylene, and ethylene-α-olefin. A single washing brush 1 for a car wash machine having the same conditions as the washing brush 1 for a car wash machine of Example 1 above is used, except that a synthetic resin fiber having a substantially corrugated cross section containing 5 parts by weight of a copolymer elastomer is used. did. The hardness of the cleaning member 7 of Comparative Example 2 was 65 °.

  Next, the washing brushes 1 for the car wash machine of Example 1, Comparative Example 1 and Comparative Example 2 configured as described above are respectively attached to a rotating test machine and rotated at a constant rotational speed of 240 rpm, while on one side. A white solid-coated steel sheet coated with pseudo-stain is prepared, and the direction of the shaft body 3 is 30 mm from the virtual circle drawn by the tip of the brush piece 6 attached to the outer periphery of the shaft body 3 rotating at the rotational speed. The white solid-coated steel sheet is disposed in a close position with the dirt surface facing the shaft body 3 and the dirt surface of the steel sheet for 1 minute while spraying cleaning water at a spray rate of 6 L / min. The pseudo-stain on the steel plate was removed by bringing the brush piece 6 into contact therewith.
