Abstract

In an attachment device, the atmospheric pressure of a lower space which is formed by a container and an attachment film and the atmospheric pressure of an upper space which is formed by a lid and the attachment film are varied to cause elastic deformation of the attachment film, so that a decorative sheet is attached to a cowl. Disposed inside the container are: a jig that puts the cowl in place; and a restriction plate which is disposed at a location close to the cowl so as to cause at least a part of the cowl to be exposed to the attachment film side, and which has a reception surface that restricts the elastic deformation of the attachment film. In addition, the reception surface is provided with a small through-hole that allows the air inside the lower space to flow therethrough.

First claim

The invention claimed is:

1. A sticking apparatus configured to stick a decorative material, which is attached to a sticking film, on an object housed in a container by changing a pressure inside a first space defined by the container and the sticking film and a pressure inside a second space defined by a lid body and the sticking film and thereby elastically deforming the sticking film, wherein
the container contains therein:
a jig configured to position the object; and
a restricting section disposed in a location that is close to or in contact with the object positioned by the jig, the restricting section having a receiving surface configured to restrict elastic deformation of the sticking film by making contact with the sticking film, wherein at least part of the object is exposed so as to face the sticking film through the receiving surface, and
the receiving surface is provided with a hole portion configured to allow air in the first space to flow therethrough.

2. The sticking apparatus according to claim 1 , wherein
the receiving surface is formed so as to be in parallel to a direction of a surface of the sticking film in a normal state in which the sticking film is not elastically deformed.

3. The sticking apparatus according to claim 1 , wherein
the receiving surface is placed above an intermediate part of the container in a height direction thereof.

4. The sticking apparatus according to claim 1 , wherein
the restricting section includes, near a peripheral part of the container, a shock-absorbing section protruding toward the sticking film from the receiving surface, and the sticking film is contactable with the shock-absorbing section.

5. A sticking apparatus configured to stick a decorative material, which is attached to a sticking film, on an object housed in a container by changing a pressure inside a first space defined by the container and the sticking film and a pressure inside a second space defined by a lid body and the sticking film and thereby elastically deforming the sticking film, the sticking apparatus comprising:
a gas flow circuit that includes a first flow channel communicating with the first space, a second flow channel communicating with the second space, and a converging flow channel into which the first and second flow channels converge;
a suction mechanism connected to the converging flow channel and configured to suction gas from the gas flow circuit;
a first measuring unit configured to measure the pressure inside the first space;
a second measuring unit configured to measure the pressure inside the second space; and
a flow rate regulating unit provided in the second flow channel and configured to regulate a flow rate of the gas in the second flow channel based on the measured pressure inside the first space and the measured pressure inside the second space.

6. The sticking apparatus according to claim 5 , wherein
the sticking apparatus includes a plurality of sticking stations, each including the container, and
the first flow channel branches off and is connected to each of the containers of the plurality of sticking stations, the first flow channel being configured to selectively communicate with one of the containers.

7. The sticking apparatus according to claim 6 , wherein
the plurality of sticking stations share the lid body,
the second flow channel includes a coupling mechanism at an intermediate position between the flow rate regulating unit and the second space, and
the coupling mechanism includes a movable-side terminal configured to move integrally with the lid body, and a fixed-side terminal provided on each of the plurality of sticking stations and configured to be detachably coupled to the movable-side terminal so that the second flow channel is placed in a communication state.

8. A sticking apparatus configured to stick a decorative material on an object, the sticking apparatus comprising:
a first sticking unit configured to place a sticking tool having a sticking film and stick the decorative material on the sticking film in a state in which a sticking surface of the decorative material is exposed; and
a second sticking unit provided in a location different from a location of the first sticking unit, and including a container configured to house the object and a lid body configured to be detachably attached to the container with the sticking film, on which the decorative material was stuck in the first sticking unit, being sandwiched between the container and the lid body, the second sticking unit being configured to stick the decorative material on the object by changing a pressure inside a first space defined by the container and the sticking film and a pressure inside a second space defined by the lid body and the sticking film and thereby elastically deforming the sticking film.

9. The sticking apparatus according to claim 8 , wherein
the sticking apparatus includes a plurality of sticking stations, each including the first sticking unit and the second sticking unit excluding the lid body, and
the lid body is shared by the plurality of sticking stations.

10. The sticking apparatus according to claim 9 , wherein
the sticking apparatus includes a suction mechanism configured to impart a suction force to the first space and the second space, and
the suction mechanism is shared by the plurality of sticking stations.

11. The sticking apparatus according to claim 9 , wherein
in two sticking stations of the plurality of sticking stations, the second sticking units are adjacent to each other, and
the lid body is moved between the second sticking units of the two sticking stations by a lid body driving unit.

12. The sticking apparatus according to claim 11 , wherein
when the first sticking unit in one of the two sticking stations performs an operation to stick the decorative material on the sticking film, the second sticking unit in another one of the two sticking stations performs an operation to stick the decorative material on the object, and when the second sticking unit in the one of the two sticking stations performs an operation to stick the decorative material on the object, the first sticking unit in the other one of the two sticking stations performs an operation to stick the decorative material on the sticking film.

13. A sticking method of sticking a decorative material, which is attached to a sticking film, on an object housed in a container by changing a pressure inside a first space defined by the container and the sticking film and a pressure inside a second space defined by a lid body and the sticking film and thereby elastically deforming the sticking film, the sticking method comprising:
a first step of positioning the object on a jig provided in the container and exposing at least part of the object through a receiving surface of a restricting section so as to face the sticking film, the restricting section being disposed in a location that is close to or in contact with the object;
a second step of, after the first step, depressurizing the first and second spaces and at this time, causing air in the first space to flow through a hole portion formed in the receiving surface; and
a third step of, after the second step, sticking the decorative material on the object by introducing air into the second space to thereby elastically deforming the sticking film toward the object, while causing air to flow through the hole portion from a side of the first space closer to the sticking film toward another side thereof across the receiving surface from the sticking film, and restricting elastic deformation of the sticking film around the object by the receiving surface.
