Definitions

• the present invention relates to an automatic installation and method for decorating embossed or unfinished glass or plastic articles.
• these items are first placed manually by an operator in a screen printing machine which deposits on each article in a predetermined pattern a sub-item. layer from a two-component organic ink.
• the articles are deposited by an operator one after the other on a transfer conveyor of these articles in a drying tunnel where they undergo a prepolymerization to sufficiently dry the ink, while leaving it slightly sticky on the surface.
• the passage time of the articles in the drying tunnel is quite long, of the order of 15 to 20 minutes.
• the articles are deposited by an operator at the exit of the tunnel in a hot stamping machine to ensure the transfer of a paper film by adhesion to the ink previously deposited on each article.
• the paper film is deposited only on the screen-printed patterns.
• Articles thus covered with a decoration with a metal relief resembling for example letters or glued patterns, are then deposited in a final package.
• the temperature in the drying tunnel is an important parameter requiring a very narrow permissible temperature range and the maintenance at a substantially constant temperature and difficult to obtain due to the drafts and the regulation of the heating elements of the dryer. kiln drying tunnel. Items cooked outside this range are defective.
• the object of the invention is to provide an automatic decoration installation in relief of glass or plastic articles which makes it possible to increase the rates of production, while reducing the scrap rate and obtaining a more qualitative and
• the invention therefore relates to an automatic installation embossed decoration of raw or finished glass or plastic material, characterized in that it comprises a support for continuous movement of articles between different stations comprising:
• the displacement support comprises a table movable in rotation or a conveyor belt
• the loading station comprises means of dedusting and / or of decontamination and / or of surface treatment
• the polymerization installation comprises at least one ultraviolet-type lamp or ultraviolet-type light-emitting diodes,
• the exposure time of each article in the prepolymerization station is about one second and at a distance from said at least one lamp or said diodes between about 5 and 10 centimeters, and
• the exposure time of each article in the polymerization tunnel is between about 30 and 45 seconds.
• the invention also relates to an automatic process for embossing raw or finished glass or plastic articles, characterized in that after having deposited the articles on a support, these articles are continuously moved and:
• a paper film is hot-laid by adhesion to the ink of said decoration of each article, and
• FIG. 1 diagrammatically shows an installation designated by the general reference 1 and intended to automatically produce rough or finished glass articles or plastic articles, a decoration with relief and giving a shiny metal appearance. gold or silver for example.
• Articles 10 are constituted for example by glass or plastic bottles of all shapes.
• the installation comprises a support 1 1 of continuous movement of articles 10 between different stations, including processing, to obtain the output of articles 10 having a relief decoration.
• the support 1 1 is constituted by a movable table rotation, such as a carousel with several processing stations.
• the support 11 may be constituted for example by a conveyor belt or by any other continuous movement system of the articles 10.
• the installation comprises a transport element 12 of the articles 10 between a storage point 13 and the carousel 11.
• This transport element 12 is constituted by a conveyor, such as for example an endless conveyor belt or by any other appropriate system of known type.
• the loading station 14 is equipped with a treatment unit of each article 10, of known type, comprising, for example, dedusting means and / or decontamination means, for example by ionized air and / or surface treatment means, for example by plasma.
• the carousel 11 comprises a station 15 for screen printing a sublayer forming a decoration on each article 10 by means of a UV ink.
• the screen printing of a UV ink uses known means including a polyester fabric screen, for example nylon, and a squeegee.
• the UV inks have, among other things, the advantage of not drying in the mesh of the screen.
• the carousel 11 is also provided with a prepolymerization station 16 disposed after the laying station 15 with respect to the direction of movement of this carousel 11.
• This prepolymerization operation makes it possible to sufficiently dry the ink previously deposited on each article 10, while leaving it slightly tacky on the surface.
• the prepolymerization station 16 comprises at least one ultraviolet-type lamp, not shown, or light-emitting diodes also of ultraviolet type, not shown.
• the exposure time of each article 10 in this prepolymerization station 16 is very short and about one second and each article 10 is placed at a distance from said at least one lamp or diodes between about 5 and 10 centimeters.
• the partial flash drying of the UV ink by means of an ultraviolet source is very fast and thus makes it possible to obtain a surface of the slightly tacky ink.
• prepolymerization stations 16 may be placed in series on the carousel 11 following one another or in parallel.
• each article 10 comprises, in a predetermined pattern, an underlayer of ink.
• the pre-decorated articles are conveyed by the carousel January 1 in a hot laying station 17 of a paper film by adhering to the previously deposited ink.
• the hot stamping station 17 is of known type and comprises for example a roll or a platinum coated with a silicone, not shown, heated to a temperature of the order of about 200 ° C.
• the marking station 17 ensures the transfer of a paper film by adhesion to the ink previously deposited on each article 10.
• the paper film is deposited only on the screen-printed patterns which makes it possible to obtain a decoration with a relief metal resembling for example letters or patterns of various shapes.
• the embossed decoration thus obtained has for example a shiny metal appearance of the gold or silver type.
• the articles 10 move continuously to an unloading station of these articles 10 where a manipulator arm, not shown, deposits these fully decorated articles on a conveying element 19, as for example a conveyor belt, of known type.
• a conveying element 19 as for example a conveyor belt, of known type.
• Articles 10 scroll continuously through a final ultraviolet polymerization tunnel of the decor previously deposited on each of these articles.
• the exposure time of each item is approximately 30 to 45 seconds.
• Articles 10 are then checked and packaged.
• the installation according to the invention makes it possible to obtain a high production rate because of a shorter cycle time than in the installations used until now, while reducing the rejection rate because of a smaller sensitivity to temperature variations.
• the articles obtained have a brighter decor and the use of a UV ink, prepolymerized very quickly allows the transfer of the hot stamping film immediately after which significantly limits the decoration cycle articles.
• the final ultraviolet polymerization makes it possible to obtain a better resistance of the decoration on the articles.
