Definitions

  • the present invention relates to a masking tool employed to protect the projection(s) of an article such as a car body from a surface treatment such as coating, plating, vacuum evaporation, phosphatizing, and the like.
  • the present invention relates to a masking method employing said masking tool to protect said project­ion(s) of said article from said surface treatment.
  • the present invention relates to a masking member which comprises a cylinder having an inlet at one end and an outlet at the other end, a plural number of cap or clip type masking members and these being put in said cylinder to be placed one upon another, and a transport­ing means arranged in said cylinder to transport said masking members successively from the inlet to the outlet of said cylinder.
  • said masking members in said cylinder of said masking tool are successively transported from the inlet to the outlet of said cylinder by said transporting means and said masking members are successively put over said projections of said article before said surface treatment.
  • said projection(s) may be bolt rod(s), boss(es), panel edge(s) and the like, and a paint such as a polyvinylchloride-sol, a tar-urethane mixture and the like is coated on said underside of said car body for corrosion, sound, and vibration proofing.
  • many masking members should be put over said projections before said surface treatment. Further, in the case of a continuous mass-­production line, said masking members should be put over said projections in a short time. Still further, in a case of a continuous mass-production line, it is desirable that said masking members be automatically put over said projections.
  • a cap or clip type masking member has been provided to protect the projection(s) of an article.
  • Said masking member is made of a foamed plastic such as a foamed polystyrene and the like (USSN 276,407).
  • said masking member(s) is(are) put over said projection(s) of said article by hand and much labor and time have been necessary to protect said projection(s) before said surface treatment.
  • an object of the present invention is to save labor and time in the case of a masking process before a surface treatment.
  • Another object of the present invention is to provide a masking method suitable for automatic operation.
  • a further object of the present invention is to provide a masking method suitable for a continuous mass-production line.
  • a masking tool employed to protect the projection(s) of an article from a surface treatment which comprises a cylinder having an inlet at one end and an outlet at the other end thereof, a plural number of masking members which are put over said projections and are put in said cylinder to be placed one upon another, and a transporting means arranged in said cylinder to transport said masking member from the inlet to the out let of said cylinder and a masking method for the projection(s) of an article by employing a masking tool which comprises transporting said masking members in said cylinder from the inlet to the outlet thereof by said transporting means, and putting said masking members over the projection(s) of an article one by one.
  • FIG. 1 to FIG. 4 relate to a first embodiment of the present invention.
  • a masking tool(120) comprises a cylinder(121) having an inlet­(122) at one end and an outlet(123) at the other end, a friction sheet(129) attached to the inside of said cylinder (121), a plural number of cap type masking members(111) put in said cylinder(121) to be placed one upon another, and a piston(124) as a transporting means.
  • Said piston(124) is inserted into said cylinder(121) from said inlet(122) thereof and a handle(126) is connected to the piston rod­(124A) of said piston wherein a pin(128) of said piston rod(124A) is inserted in a groove(127A) of a bracket(127) of said handle(126).
  • each masking member(111) has an inserting hole(112) and is made of a material, such as of plastics or a rubber such as polystyrene, polyethylene, polypropylene, ethylene-propylene copolymer, polyvinylchloride, polyvinylidene chloride, polymethacrylate, styrene-butadiene copolymer, acrylonitrile-butadiene copolymer, polybutadine polyisoprene, polyisobutylene, polychloroprene, isoprene-­isobutylene copolymer, natural rubber, polyurethane, melamine resin, urea resin, phenol resin, epoxy resin and the like; foams of said plastics or said rubber; mixture of said plastics of said rubber with a filler such as a calcium carbonate, a talc, a bentonite, a fly ash, a blast furnace slag, and the like;
  • a filler
  • a plural number of said masking members(111) are placed one upon another as above described and if desired, said masking members(111) be attached respectively by an adhesive or by melting.
  • a plural number of said masking members(111) in said cylinder(121) of said masking tool(120) are successively transported from the inlet(122) to the outlet(123) by operation of said piston(124) by said handle(126) and said masking members(111) are put over cylindrical projections (131) of an article(130) one by one as shown in FIG. 3 and after this, a paint such as a polyvinylchloride-sol, an urethane resin, an asphalt, a rubber-asphalt mixture, a tar-urethane mixture and the like is coated on the surface of said article to form a coating layer(140) as shown in FIG. 3. After coating, said masking member(111) is removed from said projection(131) as shown in FIG. 4, said coating layer(140) is not formed on said projection(131).
  • said masking tool(120) be operated by a robot and in this case, said masking members(111) are automatically put over said projection(s)(131) without the necessity of a laborer's hands.
  • said piston(124) may be operated by a pressure oil cylinder, an electromagnetic cylinder, and the like instead of said handle(126).
  • FIG. 5 relates to a second embodiment of the present invention.
  • a masking tool(220) of this embodiment comprises a cylinder(221) having an inlet(222) at one end and an outlet(223) at the other end, a plural number of cap type masking members(111) are put into said cylinder(221) to be placed one upon another, and a pair of endless belts(224),­(224) act as a transporting means.
  • Each of said endless belts(224),(224) is suspended on a pair of rollers(225),­(226) wherein one set of said rollers(225) is rotatively attached to the inlet(222) of said cylinder(221) and the other set of said rollers(226) are rotatively attached to the outlet(223) of said cylinder(221).
  • Said endless belts (224),(224) are respectively made of a friction material such as a rubber, or cloth having a flocking layer and the like, and said masking members(111) are pressed between said pair of endless belts(224),(224) in said cylinder(221) of said masking tool(220).
  • a plural number of said masking members(111) are successively transported from the inlet(222) to the outlet (223) in said cylinder(221) by driving said rollers(225), (226) by a driving means such as a motor and the like to put said masking members(111) over the projection(s) of an article one by one.
  • FIG. 6 and FIG. 7 relate to a third embodiment of the present invention.
  • a clip type masking member(211) of this embodiment has a inserting ditch(212) and a plural number of said masking members(211) are put into said masking tool(120) or (220) as same as said masking members(111) of the first and second embodiments.
  • Said masking member(211) is put over a flat type projection(231) of an article(230) to protect said projection(231) from a surface treatment.
