Definitions
- the invention relates to a method for decorating the cylindrical walls of containers, for example the cylindrical skirts of flexible tubes before the latter are filled with the product which they are intended to distribute. It relates more particularly to decoration by hot stamping or by hot plating of transfer films.
- Any type of cylindrical wall is envisaged: metallic, typically of aluminum alloy, metalloplastic or entirely plastic, mono - or multilayer.
- the problem which the invention proposes to solve relates to the decoration of the skirt of the flexible tube when the latter can only be decorated after having been shaped into a cylinder. This is immediately the case with aluminum alloy tubes. This is also systematically the case for tubes entirely made of plastic, the skirt of which is obtained by extrusion, called “plastic tubes”. This can also happen for tubes entirely made of plastic called “laminated tubes” or for metalloplastic tubes.
- the flexible plastic tubes called “laminated” include a head and a flexible skirt, obtained from a band called “laminated”, generally comprising several-plastic-layers._LcLjups_is obtained., By cutting in. a cylindrical sleeve, itself obtained by rolling a flat strip.
- the rolling is carried out so that the strip is shaped into a cylinder, the edges of said strip being placed opposite one another, generally with a slight overlap, then welded together.
- the cylinder thus formed is cut to the desired length to make the skirt, then a tube head is welded to one end of said skirt.
- plastic flexible tubes are obtained either entirely by molding (typically by injection) or, as in the case of laminates, by welding a head to a cylindrical skirt, the cylindrical skirt having in this case been obtained by extrusion a thin cylindrical plastic profile and then cut it to the desired length.
- hot stamping can be carried out on the strip before it is shaped into a cylinder with known techniques of printing on flat strips such as that described in application FR 2. 171 170 (MADAG), where the strip is marked by a printing member comprising an oscillating arm mounted on a pivot which compresses the strip which runs while remaining in abutment on a roller or also that described in US 5368680 (KURZ), where higher rates can be obtained by passing the strip to be marked and the transfer film in the air gap between a marking cylinder and at least one support cylinder.
- MADAG 171 170
- KURZ US 5368680
- Such an operation therefore requires either a decrease in the rate on the complete production line (in this case, this hardly exceeds 60 tubes / minute while the other elements of the production chain can easily reach 1 0 tubes / minute ), or the production on two or more parallel lines of hot stamping using existing devices, or even the output of the production lines for a treatment in recovery (disengaging).
- the Applicant has therefore set itself the objective of carrying out hot stamping of decorations on cylindrical objects online while respecting a production rate compatible with the production line, that is to say capable of processing at least 100 tubes. per minute, and preferably at least 120 tubes per minute.
- a first object of the invention is a method for decorating the cylindrical wall of containers, characterized in that it comprises at least the following steps: a) mobile mandrels mounted on a loop circuit are used, each mandrel having a diameter slightly smaller than the diameter of the cylindrical wall of the container and being mounted on a support capable of moving so that the axis of the mandrel remains parallel to a given direction D, the mounting of the mandrel on its support being carried out so that 'It can rotate around its axis while resisting a force exerted perpendicular to said axis; b) each container is successively brought into line with a mandrel and then fitted onto said mandrel; c) the mandrel thus coated with said container is brought into the vicinity of a pressure cylinder which can rotate about an axis parallel to said direction D; d) during its movement towards said pressure cylinder, said mandrel is rotated about its axis; e) one scrolls.
- said pressure cylinder is driven, for example using a motor, typically an electric motor, with a continuous rotational movement around said axis, said axis being fixed;
- mobile mandrels mounted on a loop circuit are used, for example mounted on a turntable. These mobile chucks are limited in number, typically a few tens.
- the mounting the mandrel on its mobile support must allow the latter on the one hand to rotate around its axis, on the other hand to resist a force exerted perpendicular to said axis.
- a rolling bearing is used.
- the mandrel is mounted on its movable support so that it can also move along its axis. In this way, a certain correction can be made, if necessary, on the longitudinal positioning of the container, that is to say on the longitudinal positioning of the decoration already printed on its wall.
- the rotary table advantageously rotates step by step, the mandrel being located at each stop in line with a zone for handling or treating the container, for example: fitting of said container by its cylindrical wall around a mandrel, deposition or marking of a decoration on the cylindrical wall, unloading of the container provided with its decoration, etc. (other stations can be used for various completions of the container).
- a station allowing the removal of the core resulting from the molding of the tube head, the removal of a cover to close the dispensing orifice, the automatic screwing a stopper, or even the fixing, by pushing in then snapping onto the neck, of a hinged capsule, etc.
- the containers are brought successively to the right of a mandrel, typically using pins mounted on a transfer chain, then fitted onto the mandrels over a length appropriate to the decor to be printed.
- the fitting is preferably carried out until the inside of the tube head abuts on the head of the mandrel, which allows to have an indexing axial decoration on the tube skirt.
- the mandrel can also be actuated by an axial translation device.
- the pressure cylinder is driven in a continuous rotation movement, preferably constant, about its fixed axis which is parallel to the direction of the axis of the mandrel.
- the. mandrel is brought into contact.
- the pressure cylinder so that it exerts a force distributed as regularly as possible on a generator thereof.
- Said distributed force is used either to deposit the decoration using the transfer film (decal), or to mark said decoration, the surface of said pressure cylinder being engraved (for example marking, hot or cold, or even form of a decoration in relief by plastic deformation of the wall of the container).
- the controlled tangential arrival of the mandrel in the vicinity of the pressure cylinder allows the support of the mandrel, designed to rotate said mandrel, not to be subjected to too violent shock.
- the mandrel coated with said container is animated with a rotational movement such that when the mandrel arrives at the pressure cylinder, the tangential speed of the cylindrical wall of the rotating container is substantially equal to the tangential speed of the surface of the pressure cylinder, typically equal to ⁇ 1%, preferably equal to ⁇ 0.5%.
- the mandrel is rotated for example by a servomotor which allows large accelerations in rotation, thus making it possible to pass from a zero tangential speed to a tangential speed equal to that of the surface of the pressure cylinder after a lapse of less time than that which corresponds to the movement of the container between the previous step of the process (for example fitting the container onto the mandrel) and the step of depositing or marking the decoration.
- a servomotor which allows large accelerations in rotation, thus making it possible to pass from a zero tangential speed to a tangential speed equal to that of the surface of the pressure cylinder after a lapse of less time than that which corresponds to the movement of the container between the previous step of the process (for example fitting the container onto the mandrel) and the step of depositing or marking the decoration.
- said pressure cylinder is a marking cylinder: it has an engraved surface according to the desired decoration.
- the force applied by the raised parts of the etched surface causes the compression of a part of the transfer film which thins and adheres to the wall of the cylindrical container.
- the marked part of the transfer film which remains stuck to the wall of the container is detached from said support strip, thus materializing the decoration to be produced. . . .
- the marking cylinder is generally a massive cylindrical block rotating around its axis. It can however take other forms, provided that the engraved surface rests on a cylindrical surface and rotates around the axis of said cylindrical surface.
- the marking is done hot with a heating marking cylinder which marks a thermal transfer film: under the effect of temperature and pressure, the plastic material of the marked area of the transfer film acquires adhesive properties and s' thins, the border between the marked part and the unmarked part becoming, after cooling, an easy tear zone.
- the support strip is kept on the cylindrical wall of the container for a certain time after it has left the marking zone. This time is sufficient to allow the support strip and the marked transfer film to cool down to a temperature which facilitates the detachment of said film by cutting along the border between the marked area and the unmarked area.
- the marking cylinder rotates about its axis, preferably with a continuous and constant speed, which facilitates the control of the rotation of the mandrel.
- the support strip provided with the transfer film can also travel at a constant speed, substantially equal to ⁇ 1%, preferably ⁇ 0.5%, at the common tangential speed of the etched surface of the marking cylinder and the wall. of the container.
- a system for advancing the strip making it possible to slow down and then to accelerate said support strip in the interval time between the start of a mandrel with a marked container and the arrival of a new mandrel with a not yet marked container. Whether at constant speed or not, the support strip passes while passing in the area of .
- marking that is to say in the air gap between the marking cylinder and the mandrel, so that it is trapped and then compressed during the mutual approach of the mandrel and the engraved surface of the marking cylinder. It scrolls between a supply coil and a reception coil, passing through a succession of rollers whose distribution makes it possible, by varying the tension of the strip, to stabilize its movement.
- any transfer film - which can in particular give an effect other than that of a metallic gloss - can be used.
- the mandrel is brought into contact with the marking cylinder so that the cylindrical wall of the body is present tangentially to the etched surface of the marking cylinder and the latter exerts a force on said mandrel through the transfer film support strip and the wall of the container, the assembly being driven by the same tangential speed.
- the axis of rotation of the marking cylinder is kept fixed and the mandrel is put into rotation before it arrives in the vicinity of the cylinder marking, ensuring that it can reach the appropriate speed before reaching said marking area.
- the position of the axis of the marking cylinder is defined relative to the trajectory of the mandrels so that when they come into contact with each other, a force is applied to the contact generator, low enough for the mandrel to be able to mechanically resist and large enough for the transfer film to be marked by the reliefs of the engraved surface of the cylinder.
- the marking device preferably using mandrels having, at least in line with the wall of the container intended to be marked, a cylindrical wall with circular cross section.
- the wall of the container is not necessarily cylindrical with a circular section but it must be flexible enough to be able to follow the circular cylindrical shape of this part of the mandrel when the container is fitted and held on said mandrel.
- the marking area of the skirt is located at a sufficiently large distance (typically corresponding to the radius of the circular cylindrical part of the mandrel) from the dispensing head because the peripheral edge of the shoulder - more rigid - is not axisymmetric.
- the bearing force is between 2 N / mm and 40 N / mm while the etched surface of the marking cylinder is brought to a temperature between 80 ° C and 250 ° C.
- the support strip remains in contact with the mandrel on a given angular opening, sufficiently large (at least 20 °, preferably at least 30 °) to allow the support strip and the marked transfer film move away from the heating block and cool down to a temperature which facilitates the detachment of the film by cutting along the border between the marked area and the unmarked area but the angular opening is limited due to the size, since she can't cut the trajectory of the containers mounted on the mobile mandrels.
- the support band is maintained contiguous to the cylindrical wall of the container -jusqu'à-ce_que_celle-cLatlessnessr ⁇ e_uoe jemp_érqtyre_ average , less than 80 ° C, preferably less than 60 ° C
- the support strip is therefore moved away from the surface of the container so that the marked part of the transfer film remaining glued to the wall of the container is detached from said support strip, thus materializing the decoration.
- the mandrel being able to make a turn on itself with the engraved surface of the marking cylinder in continuous support, the decoration can be carried out on the whole of the
- This decoration can be of axial symmetry but it is possible to produce the decoration at a desired position on the cylindrical wall of the container: after fitting of the container on the mandrel-immobile. on_fait _ojjmerJe_m. diLn_etPD-e ⁇ ectjje_ an optical determination of a pre-marked index on the container - for example during the offset printing of a decoration without a shiny gold or silver effect on the container -, and the rotation of the mandrel is calculated so that the container comes into contact with the surface of the cylinder by presenting itself in a predefined angular position.
- the device proposed in the example below includes equipment which makes it possible to perform such angular indexing.
- the decoration positioning index is pre-printed in a not very visible place, that is to say as far as possible from the most exposed place of the decoration, namely the part of the decoration designed to be seen first by the consumer (particular aesthetic aspect, brand, slogan, ).
- the imprecision of the pre-impression combined with that of the marking can give, despite the use of the optical locating device mentioned above, offsets likely to degrade the visual appearance sought for this strategic part of the decor.
- the optical tracking device mentioned above is advantageously supplemented by a second optical device, typically a video camera, connected to a correcting computer system which, using image analysis software, allows finely readjusting the position of the mandrel both angularly (modification of the angular correction mentioned above) and axially (correction using an axial translation device actuating either the mandrel or the marking cylinder).
- a second optical device typically a video camera
- a correcting computer system which, using image analysis software, allows finely readjusting the position of the mandrel both angularly (modification of the angular correction mentioned above) and axially (correction using an axial translation device actuating either the mandrel or the marking cylinder).
- the method according to the invention can also extend to the formation of a relief decoration on the cylindrical wall of containers. In such a case, it is not necessary to run a transfer film support strip since the etched surface sinks directly into the cylindrical wall.
- the the angular indexing principle mentioned in the previous paragraph can also be applied.
- the method according to the invention can also extend to the decoration of the cylindrical wall of a container in which the decoration is pre-printed using an ink or a varnish which retains or on the contrary repels the film. transfer coming to be uniformly pressed on the cylindrical wall of the container under the effect of the support of an unetched cylinder.
- Another object of the invention is a device making it possible to implement the above method applied to the decoration of cylindrical bodies, typically the cylindrical skirts of flexible tubes, characterized in that it is a machine comprising a fixed plate placed facing a rotary plate operating step by step, said rotary plate being provided with mandrels which can rotate about their axis, said axis being parallel to the axis of rotation of the plate, said mandrels being brought successively to the course of the rotation of the plate into several working zones formed on the fixed plate, these working zones comprising at least: a) a feeding zone where the cylindrical bodies are brought in front of a mandrel and then fitted around said mandrel; b) a marking zone comprising: - at least one marking cylinder in continuous rotation, preferably with a constant speed of rotation, the axis of which is placed in a place such that when a mandrel arrives at the right of said cylinder, that -this comes into contact with said mandrel by exerting a bearing force, preferably distributed
- the marking zone can include more than one marking cylinder, which makes it possible to increase the production rates by simultaneous treatment of several containers. This nevertheless requires an arrangement of the tray and the other work areas since the containers must be moved everywhere and treated simultaneously in a group.
- this device is advantageously supplemented in the marking zone by a device for passing through a transfer film support strip, making the strip pass so that it passes through the film. space between said marking cylinder and the surface of the cylindrical body when a mandrel is brought into this working area, said device being provided with systems making it possible to control the tension of the strip, in particular at the outlet of the air gap of the marking device.
- the marking cylinder is preferably heated.
- the new device can advantageously result from the arrangement of an existing device, called a capper, in which one can find:
- a capping area - optional - where, typically, the plugs are brought individually to the right of a tube, rotated and then screwed onto the threaded neck of the head (in the case of screw caps) or pushed in then snapped onto said neck (in the case of rigid capsules provided with pivoting covers (service capsules)).
- this zone preferably located directly upstream of the marking zone; this zone can also be equipped with an additional device, typically a video camera, connected to a correcting computer system which, using image analysis software, allows fine adjustment of the position of the mandrel to the angularly and axially
- OJ OJ - said marking area; - an - optional - control zone (typically using a video camera), of the decorations obtained (positioning, quality of transfer, detachment, highlighting) - said evacuation zone of the flexible tubes.
- the workstation located directly upstream of the hot stamping station is provided with an optical tracking system making it possible to detect, using a photoelectric cell, the angular position of a spot materializing a particular point known from the background already printed.
- the mandrels are provided with drive means, which allow them to be actuated in rotation by running a belt.
- the drive belt 25 is toothed and drives a toothed wheel integral with the axis of rotation of said mandrel.
- the mandrel at the marking station is in phase with the rotation of the marking cylinder - the speed of rotation of the mandrel is defined so that the cylindrical surface of the body and the engraved surface of the marking cylinder have the same tangential speed - , it suffices to detect the angular position of the pre-printed index on the body placed on the mandrel located at the station (n-1) to know the angular offset compared to the mandrel being marked and consequently compared to the engraved surface of the marking cylinder. Using an appropriate algorithm, the automation calculates the correction necessary to bring the body in the right position and at the right speed to the marking station n. This correction is made during the movement of the mandrel from the station (n-1) to the station (n).
- the use of a common drive belt on these two stations, said belt itself being driven by a single servomotor improves the accuracy by avoiding any backlash resulting from a change of engine or belt .
- the same capper can be used to perform relief decorations: the support strip is removed from the transfer film and the drive device for said strip.
- Another object of the invention is a method for decorating the cylindrical walls of containers in which, instead of marking the areas defining the decoration, they are printed with a varnish or an ink called "in love" that is to say an ink comprising an adhesion promoting agent promoting the adhesion of the transfer film to the printed decoration, typically a varnish or an ink comprising organic particles (for example acrylic, etc.) under-polymerized.
- the cylinder is then a simple support cylinder exerting pressure on the wall of the container so that the part of the transfer film adhering to the printed part of the wall is detached from the support strip. when the latter is distant from the wall of the container.
- the method thus comprises the following steps: a) .on. used mobile mandrels.
- each mandrel having a diameter slightly less than the diameter of the cylindrical wall of the container and being mounted on a support capable of moving so that the axis of the mandrel remains parallel to a given direction, the mounting of the mandrel on its support being carried out so that it can rotate around its axis while resisting a force exerted perpendicular to said axis; b) each container is brought successively to the right of a mandrel then fitted onto said mandrel; c) the cylindrical wall of each container is printed according to the desired decoration with an ink or a varnish promoting the adhesion of a transfer film; d) the mandrel thus coated with said container is brought into the vicinity of a pressure cylinder, said cylinder being driven in a rotational movement about its axis; e) during its movement towards said pressure cylinder, said mandrel is rotated at a speed correlated with that of the pressure cylinder so that when the mandrel arrives at
- another object of the invention is a process similar to the previous one, in which the cylindrical wall of each container is on the contrary printed according to the desired decoration with an ink or a varnish comprising an adhesion inhibiting agent, that is to say that is to say an ink or a varnish preventing the adhesion of said transfer film to the printed decoration, typically an ink or a varnish comprising particles based on silicones and / or waxes.
- an adhesion inhibiting agent that is to say that is to say an ink or a varnish preventing the adhesion of said transfer film to the printed decoration, typically an ink or a varnish comprising particles based on silicones and / or waxes.
- the force causes compression of the transfer film and results in the adhesion of a part of said transfer film on the unprinted part of the cylindrical wall of the container.
- said transfer film has adhesive properties such as for example a hot melt.
- a heating pressure cylinder will be used so that when the pressure cylinder is pressed on the sleeve through the transfer film, the latter acquires said adhesive properties and thus adheres strongly to the unprinted part of the wall. cylindrical container.
- a device with a rotary plate such as that described above can be used to carry out such decorations: a printing station for the tube skirt is provided upstream from the station for pressing the support cylinder against the wall of the tube to through the support strip of the transfer film.
- printing can be carried out using a conventional device, typically. offset machine placed. sure. JaJigne de_faJorication_eo 3mont of said rotary table device. It is also possible to envisage carrying out the printing by arranging a printing station in the rotary plate device itself, upstream from the station where the transfer film is pressed against the wall of the container. Printing can for example be carried out by flexography using an engraved cylinder. The angular indexing of the decoration to be printed can be carried out using the method described above, with the difference that the printing cylinder takes the place of the marking cylinder.
- Figure 1 schematically illustrates a hot stamping device of cylindrical bodies of the prior art
- FIG. 2 schematically illustrates a device for hot marking of cylindrical bodies according to the invention.
- Figure 3 illustrates an enlarged detail of Figure 2a, more particularly showing the vicinity of the hot stamping area.
- This device comprises a marking cylinder 1 having a planar etched surface 2.
- the marking block is heated and allows hot marking using a thermal transfer film. It moves tangentially to the wall of the container 3. Once the entire cylindrical wall is marked, it is moved away from the support strip 4 of heat transferable film and brought back in ⁇ mont to make a new pass on a new container. It therefore performs an alternating movement of advance - retreat, of step type at each cycle.
- Such an alternating movement slows the production rates, so that even the most efficient machines do not exceed 60 tubes / minute
- the device illustrated schematically in Figures 2 and 3 corresponds to a station of a machine called “capper” which performs the parade and in high speed a number of finishing operations on flexible tubes.
- This machine comprises a fixed plate placed opposite a rotary plate operating step by step. The movement of the plate is symbolized in FIG. 2 by the arrow referenced R.
- the rotary plate is provided with mandrels, such as the mandrels referenced 12 and 13. These mandrels are mounted on the rotary plate so that their axis remains parallel to the axis of rotation of the plate and that they can rotate around their axis. They are further guided so that they can perform a movement of axial translation of small amplitude (of the order of a millimeter). Said mandrels follow a circular trajectory 20 and are brought successively during the rotation of the plate into several working zones provided on the fixed plate:
- a hot marking zone 10 comprising: a marking cylinder 11 in continuous rotation R ′. a device 30 for passing a support strip 14 of heat transferable film, bringing said strip into the air gap of the marking device; said device being provided with a system of rollers 31 the arrangement and the controlled drive speed make it possible to control the tension of the support strip 14 at the outlet from the air gap of the marking device - a zone for evacuating the flexible tubes thus decorated (not shown)
- the mandrel 12 intended to arrive at the marking station (where it is indicated by the reference 13) is rotated about its axis by virtue of the movement of a toothed drive belt 16 which drives a toothed wheel 15 integral with the axis of rotation of said mandrel.
- the drive belt 16 is itself actuated by a servomotor (not shown), which makes it possible to pass from a zero tangential speed to a tangential speed equal to that of the heating marking cylinder.
- the latter rotates at a speed such that the etched surface of the marking cylinder 11 moves in a given time over a circumferential length equal to the perimeter of the tube skirt.
- a servomotor not shown
- This speed must be reached and regulated after a period of time less than that which corresponds to the movement of the container from one working area to the next, that is to say, continuing our example, less than 0 , 3 s. It therefore requires a servomotor capable, via the belt 16 and the toothed wheel 15, of driving the mandrel with accelerations clearly greater than 15 r / s 2 .
- the support strip remains in abutment on the mandrel on a given angular opening, sufficiently large (at least 20 °, preferably at least 30 °) to allow the support strip and the transfer film marked with s '' move away from the heating block and cool down to a temperature facilitating the detachment of the film by cutting along the border between the marked area and the unmarked area (duration of the support hold in the order of 0.02 s) .
- the angular opening is however limited due to the bulk, since it cannot cut the trajectory of the containers mounted on the mobile mandrels
- the work station located directly upstream of that of the hot stamping the position of which is symbolized by the mandrel 12 is provided with a system optical tracking 40 for detecting using a photoelectric cell the angular position of a spot materializing a particular point known from the already printed decoration.
- the mandrel 12 is provided with a toothed wheel 15 integral with its axis of rotation, which makes it possible to actuate the said mandrel in rotation by running the drive belt 16.
- the notched belt 16 is passed to the marking station (station n, the position of which is symbolized by the mandrel 13) and to the station directly upstream (station (n-1), the position of which is symbolized by the mandrel 12), so that the mandrels are in constant contact with said belt from the start of the locating step (post (n-1)) to the end of the marking step post n).
- the movement of said belt is regulated by a single servomotor.
- the two mandrels placed in these work stations rotate in synchronization, and the speed of rotation of the mandrel 13 is defined so that the cylindrical surface of the body and the engraved surface of the marking cylinder 11 have the same tangential speed, it suffices to detect using the optical locating device 40 the angular position of the index pre-printed on the body placed on the mandrel 12 located at the station (nl) to know the angular offset with respect to the cylindrical body of the mandrel 13 and consequently with respect to. the. engraved surface of the marking cylinder. Using an appropriate algorithm, the automation calculates the correction necessary to bring the cylindrical body of the mandrel 12 in the right position and at the right speed to the marking station n. This correction is made during the movement of the mandrel 12 from the station (n-1) to the station (n).
- the optical locating device 40 is advantageously supplemented by a video camera (not shown) connected to a computer system which, using image analysis software, makes it possible to automatically readjust the position of the mandrel to the both angularly (modification of the angular correction mentioned in the previous paragraph) and axially (correction
- ADVANTAGES o hot compression of the tubular wall also has the beneficial 0 effect of dimensionally stabilizing the cylindrical wall of the body, in particular when the latter is made of plastic.
