Definitions
- the present invention relates to a device for the continuous manufacture of blanks for the production of boxes or lids, said blanks comprising a rigid core composed essentially of a material sensitive to moisture and / or considered to be bacteriologically impure in its subsequent conditions of use, said rigid core being completely wrapped in a film of flexible synthetic material.
- the invention also relates to the products obtained by the implementation of the device according to the invention, namely the blanks and the packaging obtained from said blanks.
- the invention relates generally to the field of the implementation of techniques and methods making it possible to obtain, from materials sensitive to humidity and / or considered to be bacteriologically impure, a product whose technical resistance in a humid environment approaches "dry" and bacteriologically acceptable characteristics.
- the device which is the subject of the present application uses two (or more) materials so that the external material forms a sort of second skin while not being integral with the internal material in order to allow good recycling conditions.
- the external material will be a film (polyethylene, polypropylene or other) which must envelop the rigid core to be protected as precisely as possible on all of its faces.
- the rigid (or semi-rigid) core will essentially consist of a corrugated cardboard blank comprising fold lines, suitable cutouts, etc.
- the blanks thus produced can be shaped either as a single box, or in trays, or in a box type "American box", this without limitation.
- composite blanks are particularly advantageous for recycling the waste products used, which is not currently possible.
- US-A-2 613025 generally describes a cardboard blank wrapped between two sheets of flexible plastic material welded on the periphery.
- the cardboard blank has folds made before the cardboard is protected by the plastic film.
- the final shaping is carried out in a conventional manner, by film-film heat sealing.
- patent EP-A-0375643 (NORPAPP) describes a corrugated cardboard blank for making boxes or lids.
- the blank is wrapped by a waterproof plastic film.
- the film is loosely mounted, which creates the risk of water condensation in the event of thermal variations and hygrometric, therefore a deterioration of the blank in terms of its physical resistance and its bacteriological qualities.
- This patent describes in particular blanks completely wrapped in plastic film over their entire periphery, in particular at all of the blunt edges, such as incisions or slits.
- the blanks proposed are not satisfactory, the finished products obtained by their implementation not being sufficiently resistant. Resistance can only be obtained by the use of staples, which is strictly prohibited in certain industries, in particular food.
- the first object of the invention is to propose a machine (or device) for obtaining composite blanks.
- the invention also relates to improved composite blanks obtained by the use of the aforementioned machine.
- a device is proposed for the continuous manufacture of composite blanks for the production of boxes or lids, said blanks comprising a rigid core composed essentially of a material sensitive to humidity and / or considered to be bacteriologically impure in the subsequent conditions of use, said rigid core being completely wrapped in a film of flexible synthetic material, characterized in that it essentially comprises:
- solder-cut station comprising an electrode and a counter-electrode each disposed on a support comprising the necessary tools and forms, said supports being opposite and at least one of them being movable in the direction the second, said solder-cut being intended to connect them hermetically the two films on each of the free edges of the cardboard blank and to prepare the gluing zones for the production of the finished products.
- the subject of the invention is also the composite blanks thus obtained.
- FIG. 1 is a schematic top view of a device according to the invention.
- FIG. 2A is a more precise schematic view from above of a description according to the invention.
- Figure 2B is a side elevational view of the device of Figure 2A;
- FIG. 3 is a partial sectional view at the electrodes and against welding-cut electrodes
- FIG. 4 schematically illustrates the production of holes in the film by heating tips;
- FIG. 5 schematically illustrates the production of welds with cuts in the film, then allowing the mounting of the final packaging in an automatic manner on conventional machines.
- the device according to the invention essentially comprises a supply of blanks (2) of cardboard, or similar product, brought on a conveyor (3).
- the film (2) is brought between two films, respectively upper and lower, not shown in this figure, which are welded upstream of the blank by a transverse welding clamp to the zone referenced (4).
- the films pass through a lateral tensioning zone (5), comprising symmetrical means for tensioning the films in the direction perpendicular to their direction of advance.
- This zone also includes welding-cutting means which will be described later.
- the cardboard blank (2) here arranged in a direction different from that shown in FIG. 1, is supplied from a storage magazine (7) of known type. It is extracted therefrom in a conventional manner and is brought to a conveyor belt (8). At the end of the strip (8) the blank is sandwiched between two respectively upper (9) and lower (10) films fed from motorized reels (11, 12) in a manner known per se.
- the coils and the power supply are such that the films are brought into longitudinal tension, with known devices of brakes and cells.
- the two films are welded together and cut by a transverse sealing bar (13).
- the films are taken laterally by the clamps (14) each consisting of two motorized bands pulling the films outwards relative to the cardboard blank, before and during the passage through said zone (26).
- the bands (14) are divergent to achieve tension. It is at this level that the two welded-cut supports (15,16) are shown schematically in Figure 3.
- the two supports are two supports equipped with electrodes (17) and counter-electrodes (18) and with sealing bars intended to connect together the lower and upper films already pre-positioned and to prepare the areas which will be used for the glue for mounting the final packaging.
- the two supports are equipped with electrodes and counter-electrodes allowing to marry all the forms of the blank to be protected by maintaining the holes and notches both on the periphery and in the body of the product (holes for stacking, ventilation, water drainage, etc.).
- Said supports will have a height-adjustable stroke in order to be able to pass products to be protected of different thicknesses and so that the welds of the two films are as close as possible to the edges of the product.
- the two supports will have openings (19) at the level of the holes and notches to be released, making it possible to evacuate the surplus films by suction (20).
- the gluing zone (22) is prepared for the final shaping of the packaging.
- a "window" will be created in the film by means of a seal around the perimeter and the suction of the piece of film corresponding to the area of gluing.
- the geometric shape of the "window” can be variable.
- Gluing zones will also be provided in order to be able to position a glued cover on the finished packaging. These zones will be arranged in the same way as the above-mentioned assembly zones. It goes without saying that we can combine the different principles of preparation of the gluing areas.
- the finished products will either be stacked in a store (25) in order to make bundles which will then be taken up to be put on assembly machines, or transferred directly to the assembly machines.
