Definitions

  • the present invention relates to a method for the attaching and removing of a masking member.
  • adhesive tape has been used as a masking member. Nevertheless, it may take much labor to attach and remove adhesive tapes to said masking parts. Accordingly, a masking member using polystyrene foam as a material is provided instead of adhesive tape (for instance, Tokkai Sho 64-43376).
  • a masking member (1)A consisting of a panel body (2)A on whose underside an adhesive layer (3)A is coated as shown in Fig.8, a plug type masking member (1)B consisting of a flange part (3)B as shown in Fig.9, a masking member (1)C consisting of a cylindrical body having an inserting hole (3)C as shown in Fig.10, a masking; member (1)D consisting of a panel body (2)D having a pinching ditch (3)C having a taper shape in the entrance of said pinching ditch (3)C as shown in Fig.11, a masking member (1)E consisting of a vessel body (2)E having a knob (3) E standing from the botton of said vessel body (2)E as shown in Fig.12, a masking member (1)F standing from the top of said vessel body (2)F as shown in Fig.13, and the like are provided.
  • said masking member (1)A is used in a case where the masking part is a plane
  • said masking member (1)B and said masking member (1)E are respectively used in a case where the masking part is a hole
  • said masking member (1)C is used in a case where said masking part is a projection or pole
  • said masking member (1)D is used in a case where said masking part is a panel
  • said masking member (1)F is used in a case where said masking part is a projection.
  • said masking parts may be more than 200 parts for each car-body. Therefore it has been a very significant problem of how to attach quickly and surely said masking members to said masking parts.
  • the present invention provides a method for the attaching or removing of a masking member where said masking member is attached and removed by pinching said masking member by a pincers as a means of solving said problem of the prior art.
  • Said many types of masking members are pinched by said pincers to attach and remove to/from said masking parts.
  • Said pincers can hold said masking members mechanically. Accordingly, in the present invention, the mechanically attaching and removing of a masking member without work by hand has become possible and a fully automatic process of surface treatmemt using a masking member can be attained.
  • Fig.1 to 7 show the embodiment of the present invention and Fig.1 is a front view of a pincers
  • Fig.2 is a diagram showing the attaching and removing of said masking member (1)A
  • Fig.3 is a diagram showing the attaching and removing of said masking member (1)B
  • Fig.4 is a diagram showing the attaching and removing of said masking member (1)C
  • Fig.5 is a diagram showing the attaching and removing of said masking member (1)D
  • Fig.6 is a diagram showing the attaching and removing of said masking member (1)E
  • Fig.7 is a diagram showing the attaching and removing of said masking member (1)F
  • Figs.8 to 13 show many types of masking members
  • Fig.8 is a perspective view of said masking member (1) A
  • Fig.9 is a perspective view of said masking member (1)B
  • Fig.10 is a perspective view of said masking member (1)C
  • Fig.11 is a perspective view
  • a pincers (10) comprise a Y-shaped supporting frame (11), a a pair of movable arms (12), (12) pivotally attached to the ends of said frame (11), spikes (12)A, (12)A respectively formed at the ends of said movable arms (12), (12), a magnetic cylinder (13) connected to the root of said supporting frame (11), and links (14), (14) connecting a piston rod (13)A of said magnetic cylinder (13) with said movable arms (12), (12).
  • said magnetic cylinder, (13) comes into action to pull said piston rod (13)A into said magnetic cylinder (13) as shown in Fig.2, and said movable arms (12), (12) are closed reciprocally by said links (14), (14) to stick said spikes (12)A, (12)A into the side of said panel body (2)A of said masking member (1)A and thus said masking member (1)A is held by said pincers.

  • Said masking member (1)C is attached to said projection (21)C by inserting said projection (21)C into said inserting hole (3)C of said masking member (1)C.
  • said spikes (12)A, (12)A of said movable arms (12), (12) of said pincers (10) are pressed into the upper and lower surfaces of said masking member (1)D to hold said masking member (1)D by said pincers (10) as shown in Fig.5 the same as the case of said masking member (1)A.
  • Said masking member (1)D is attached to said panel masking part (21 )D of said article (20) by inserting said panel masking part (21)D into said pinching ditch (3)C of said masking member (1) D.
  • said spikes (12)A, (12)A of said movable arms (12), (12) of said pincers (10) are pressed into the side of said knob (3)E of said masking member (1)E to hold said masking member (1)E by said pincers (10) as shown in Fig.6 the same as the case of said masking member (1)A.
  • Said masking member(1)E is attached to said hole by inserting said vessel body (2)E into said hole (21)E.

Abstract

L'objet de l'invention réside dans le fait que, lorsque l'on applique un traitement de surface à la surface d'un article, il est possible de poser automatiquement une matière de masquage afin de protéger une partie de la surface de l'article, à laquelle le traitement de surface ne doit pas être appliqué, sur ladite partie ou de la retirer de cette dernière. A cette fin, la matière de masquage est serrée à l'aide d'une pince afin de la poser sur ladite partie ou de la retirer de celle-ci.
