Abstract

A method and apparatus for manufacturing a film coated article by placing a pre-molded film into a loading station. The film has a decorative surface and a backing surface. The decorative surface is positioned juxtaposed the loading station. The film is transferred to a loader. The loader is positioned juxtaposed the backing surface. The loader and film are positioned in an open mold press between a cavity and a core. The film is transferred from the loader to the cavity. The decorative surface of the film is positioned juxtaposed the cavity. The cavity mates with the film and retains the film in position during the molding operation. The press is closed and a polymeric material is injected against the backing surface of the film. The polymeric material produces a molded article having a rigid substrate fused to the backing of the film and displaying the decorative surface. The press is opened and the molded article is transferred from the cavity to an unloader. The decorative surface of the article is positioned juxtaposed the unloader. The molded article is transferred to an unloading station and the unloader releases the molded article.

Dependent claims

A method of manufacturing a film coated article comprising the steps of:

providing a pre-molded thin flexible film having a decorative surface and a backing surface, said pre-molded thin flexible film having a three-dimensional shape;
moving a loading station to a first position accessible to an operator;
after said moving step, placing said pre-molded three-dimensional thin flexible film into said loading station and smoothing said pre-molded three-dimensional thin flexible film so that there are no wrinkles in said pre-molded three-dimensional thin flexible film, said decorative surface juxtaposed and mating with said loading station, said loading station retaining said pre-molded three-dimensional thin flexible film in an unwrinkled state;
after said placing step, moving said loading station from said first position to a second position, said second position being located above said first position and freeing said first position to receive said article;
after moving said loading station, transferring said pre-molded three-dimensional thin flexible film from said loading station to a robotically controlled loader, said loader juxtaposed and mating with said backing surface, said loader retaining said pre-molded three-dimensional thin flexible film in an unwrinkled state;
after transferring said pre-molded three-dimensional thin flexible film to said loader, positioning said loader and said pre-molded three-dimensional thin flexible film between an open mold press, said press having a cavity and a core;
after said positioning step, transferring said pre-molded three-dimensional thin flexible film from said loader to said cavity, said decorative surface juxtaposed and mating with said cavity, said cavity retaining said Pre-molded three-dimensional thin flexible film in an unwrinkled state;
closing said press and injecting a polymer material against said backing surface to produce the film coated article having a rigid substrate of the injected polymer material fused to said backing and displaying said decorative surface;
opening said mold and transferring said article to an unloader, said decorative surface juxtaposed said unloader;
transferring said molded article to an unloading station positioned near said first position while said loading station is in said second position;
and
releasing said molded article from said unloader at said unloading station.

providing a pre-molded thin flexible film having a decorative surface and a backing surface, said pre-molded thin flexible film having a first three-dimensional shape;
moving a loading station to a first position accessible to an operator;
after said moving step, placing said pre-molded three-dimensional thin flexible film into said loading station and smoothing said pre-molded three-dimensional thin flexible film so that there are no wrinkles in said pre-molded three-dimensional thin flexible film, said pre-molded three-dimensional thin flexible film having a decorative surface and a backing surface, the loading station having a second three-dimensional shape mating with said first three-dimensional shape;
after said placing step, moving said loading station to a second position and freeing said first position to receive the film coated article;
providing a robotically controlled loader;
after moving said loading station, transferring said pre-molded three-dimensional thin flexible film from said loading station to said loader, said loader juxtaposed said backing surface and having a third three-dimensional shape mating with said first three-dimensional shape, said loader retaining said pre-molded three-dimensional thin flexible film in an unwrinkled state;
after transferring said pre-molded three-dimensional thin flexible film to said loader, positioning said loader and pre-molded three-dimensional thin flexible film between an open mold press, said press having a cavity and a core, said cavity having a fourth three-dimensional shape mating with said first three-dimensional shape;
after said positioning step, moving said loader to position said pre-molded three-dimensional thin flexible film within said cavity;
after moving said loader, transferring said pre-molded three-dimensional thin flexible film from said loader to said cavity, said decorative surface juxtaposed said cavity, said cavity retaining said pre-molded three-dimensional thin flexible film in an unwrinkled state;
closing said press and injecting a molten plastic material that forms a rigid substrate against said backing surface to produce said molded article having said substrate fused to said backing and displaying said decorative surface;
opening said mold and transferring said molded article to a robotically controlled unloader, said decorative surface juxtaposed said unloader;
and
transferring said molded article to an unloading station near said first position, and releasing said molded article from said unloader at said unloading station.
