Definitions

  • the invention relates to a method for the dry printing of a workpiece or material to be printed using a hot stamping foil and a stamp and using heat, pressure and time, in which the workpiece and the stamp moves towards one another, with the hot stamping foil being clamped in contact, heat is transferred and moved away again, the hot stamping film being stuck onto the workpiece in accordance with the stamp and being removed from the workpiece after a cooling time, with the exception of the printed image.
  • a device for this which has a receiving station for the workpiece or printed matter, a cyclical or continuously operating feed device for the hot stamping foil, a stamping die made of elastically deformable material that can be moved relative to the receiving station, and a heating device for the stamping die.
  • the invention can be used in the direct hot stamping of workpieces, in particular on elastically flexible tubes, bottles or the like. It can also be used for hot embossing of printed matter, in particular labels, during sheet rotation or the like, that is, where the printed matter is thin-walled web-shaped and has no appreciable elastic resilience.
  • the hot stamping foil printing mentioned here is a dry printing process in which the hot stamping foil is glued or melted onto the surface to be printed.
  • the hot stamping foil itself consists of a carrier tape, a separating layer, expediently a protective lacquer, the actual ink layer, which often contains an additional metal layer, and the adhesive or connection layer to the surface to be printed, which is usually made of plastic.
  • a combined lifting and unrolling method in which the stamp is brought into contact with the workpiece by continuous application over the entire stamp surface and the stamp at least in the area of the stamp corresponds to the shape of the workpiece Is brought into shape.
  • the direction of movement of the continuous application is directed transversely to the working direction, that is to say to the direction in which the individual workpieces to be embossed are guided by the corresponding device. Workpiece and embossing die are thus moved towards each other, whereby the workpiece often stands absolutely still.
  • the stamp is so resilient due to its shape, its pronounced thin walls and the use of flexible material for its manufacture that this flexibility can be used to apply the stamp to the workpiece during the stamping process and to form.
  • a device for dry printing of a workpiece using a hot stamping film in which the stamp body of the stamp and ultimately the entire stamp are so thin and elastic that a local elastic deformation of the stamp in the system on the workpiece is possible to compensate for elevations and sink marks and thus reduce rejects.
  • the embossing stamp is equipped with a positive power transmission relief on the back of the stamp surface and a pressure cushion is used for the locally elastic deformation. This is aimed aims to put as little thermal and mechanical stress on the sensitive embossing die as possible.
  • the stamp surface can also be arranged on an endless belt, the embossing process then taking place with line contact.
  • line contact when rolling requires relatively high temperatures of the die because of the necessarily short contact time.
  • particularly high temperatures damage the die and lead to a reduction in the service life.
  • the arrangement of a positive power transmission relief on the back of the stamp surface brings about a certain complication and increases the manufacturing effort for the stamp.
  • the invention is based on the object of demonstrating a method of the type mentioned at the outset and an associated device by means of which it is possible to improve the adhesive strength of the embossed printed image on the workpiece or the printed material, and in particular with high outputs.
  • this is achieved in the method in that the surface of the workpiece, the hot stamping foil and the thin stamping die are moved in the same direction at the same or the radii corresponding speeds in mutual contact with surface contact and that the speed and the wrap angle or the flat distance Contact time of the stamp and the cooling time of the hot stamping foil can be controlled.
  • the new method makes it possible to determine the contact time on the one hand and the cooling time on the other hand independently of one another and to apply them uniformly to all surface areas of an embossing stamp or stamp surface. This also results in an improved, because uniform adhesive strength of the embossed image on the workpiece.
  • the contact time can be increased almost arbitrarily and sensitively via the speed of the movement in the working direction and the chosen wrap angle in coordination with the pulsating heating time of the die.
  • the contact time and the cooling time can be easily and precisely changed or adjusted to the respective printed image, which advantageously opens up the possibility of lowering the average temperature of the embossing stamp, because a sufficiently high contact time can be selected for the heat transfer. In this respect, the lifespan of the stamp increases considerably.
  • embossing itself high speeds can easily be achieved are used, so that a considerable increase in performance results even with a single-head design of a corresponding device.
  • the adhesive strength of the embossed image is not affected.
  • the embossing pressure can essentially be influenced by the three parameters of heat, pressure and time.
  • the new method also allows the use of stamps with multiple uses, which can be used to achieve an additional increase in performance. Due to the separately preselectable contact time on the one hand and the cooling time on the other hand, a case-specific adaptation to different materials of the hot stamping foil on the one hand and the workpiece or the printed material on the other hand can also be achieved. This means that the hot stamping foils that can be used can be used more universally and ultimately it does not matter what special plastic the tube or bottle to be stamped is made of. Compared to the lifting method with the rigid stamp, there is the further advantage that the contact pressure is only applied a portion of the surface of the die must be effective at the same time.
  • the speed and wrap angle are kept constant during embossing, so that different areas of the embossing die come into contact with the workpiece one after the other, but contact times match for each area and cooling times result.
  • An increase in speed for example, has the same effect on every surface area of the printed image. As new areas come into contact, other areas run out of the wrap angle and come out of contact. Matching contact times occur for each surface unit or for each location on each surface. An increase in speed can be counteracted by increasing the wrap angle in order to achieve the same results.
  • the heaters can also be used in a pulsating and timely manner, it is clear that the adhesive strength of the embossed image can be improved without restricting the output. It is therefore easily possible to achieve working speeds which correspond to those of screen printing stations or which are still comparatively higher. This is already the case when using a single use.
  • a force tape, pressure pad, a series of pressure rollers, or the like can be used to press the die; the thin embossing stamp is only guided according to the surface of the workpiece during the embossing. This takes place parallel to each other in surface contact in the working direction. It is understood that before reaching the surface contact and after removing the same, the embossing stamp, the hot stamping foil and the workpiece also have to be moved towards or away from each other, as is already done in the lifting process.
  • the hot stamping foil can be guided around the workpiece with a larger wrap angle than the stamping die, so that contact of the stamping stamp over the hot stamping foil with the workpiece is avoided for the realization of the cooling time on the corresponding cooling path.
  • the outward movement of the embossing stamp is possible regardless of the outward movement of the hot stamping foil from the workpiece.
  • the embossing stamp is preferably locally heated discontinuously. These heating pulses are adjusted to the wrap angle for the contact time, in such a way that the sufficient amount of heat is available during the contact time and can be transmitted. This takes place at a preferably relatively low temperature level in order to increase the service life of the stamp.
  • the device for carrying out the method is characterized according to the invention in that a drive for moving the surface of the workpiece and a drive for the embossing die are provided in the working direction, and a device for synchronizing the two drives and the feed device with regard to the speeds in the working direction are provided and that preferably adjustable guide devices are provided for the workpiece, the hot stamping foil and the stamp, which at least during stamping make mutual surface contact during the common movement in the working direction bring about. At least the workpiece or the material to be printed, the hot stamping foil and the stamping die are thus moved synchronously in order to achieve the surface contact that the guide devices enable. A relative movement of the parts in the working direction is avoided.
  • the embossing stamp can be arranged on a belt that moves back and forth in the working direction or on an endless belt. This serves to guide the embossing stamp.
  • the embossing stamp itself can be constructed depending on the application. It can be provided in a single or multi-use arrangement on the belt. Due to the local heating, it has heated and unheated zones.
  • masks can also be provided on the belt, that is to say unheated areas which essentially serve for uniform placement and guidance. It is easily possible to start the surface contact with an unheated mask and to use the embossing of the embossing stamp on part of the wrap angle for the actual contact time in which heat is transferred.
  • a force band an arrangement of pressure pads or pressure rollers is provided which keep the stamp or the band in surface contact with the hot stamping foil and the tool during the stamping. Although only a comparatively small force can be transmitted via these pressure elements this force may still be necessary to enable and guarantee the correct placement of the die.
  • the embossing die itself is a very thin-walled, flexible element which, in many cases, is also subject to considerable bending stress. In particular when an embossing stamp is arranged in an endless form or on an endless belt, the permanent bending stress occurs during work.
  • the force band or the other pressing elements can be provided with a device for the sensitive adjustment of a pretension or a pressing force. The contact forces should not only be small, but also adjustable.
  • a workpiece 1 is indicated in FIG. 1, which may consist, for example, of a blown plastic bottle, on the partial circumference of which the printed image is to be embossed.
  • the workpiece 1 is held in a pick-up station 2, which is only indicated, the pick-up station being part of a conveyor device (not shown) with which the workpieces are successively moved through the device in cycles. This can be done, for example, in the direction of arrow 3 or also perpendicular to the image plane.
  • the receiving station 2 is provided with a drive 4 in order to move the workpiece 1 in rotation according to arrow 5 during the stamping process (FIG. 2).
  • Arrow 5 or arrow 3 thus simultaneously represent the working direction in which the workpieces 1 are embossed one after the other and pass through the device.
  • a hot stamping foil 6 is provided above and initially at a distance from the workpiece 1 guided over rollers 7, 8, which are part of a guide device for the hot stamping foil 6.
  • the rollers 8 can be fixed in place, while the rollers 7 are arranged so that they can be pivoted downward into the region of the workpiece 1 (FIG. 2), so that they apply the hot stamping foil 6 to the circumference of the workpiece 1.
  • the result is an overall wrap angle, via which the hot stamping foil 6 is in contact with the surface of the workpiece 1, which is composed of a wrap angle 9, which represents the contact time, and a wrap angle 10, which represents the cooling time.
  • the hot stamping foil 6 also has a drive 11 which is only indicated schematically and which here intermittently, ie intermittently, feeds the hot stamping foil 6 according to arrow 3.
  • the hot stamping foil 6 there is a strip 12 which is designed as a finite strip strip and has a drive 14 which is cyclically controlled to and fro according to arrow 13.
  • the band 12 can consist of a piece of plastic film, a thin metal band or the like. It has an embossing stamp 15 at least at one point, with a base body 16 formed by the band 12, a stamp body 17 and a stamp surface 18 which is ultimately designed in accordance with the desired print image.
  • the stamping die 15 is heated in a pulsating manner by means of a heating device 19.
  • the embossing die 15 can be designed in detail, as is also shown and described in DE-PS 34 21 029 or DE-PS 38 29 297.
  • the belt 12 or the embossing die 15 is provided and movably guided with the aid of the drive 14 and a further roller 20, which in turn form a guide device.
  • a base plate 21 is assigned to the elements described, which is essentially for the arrangement of a Kraftband 22 is used, which is provided with a device 23 for sensitive application of a bias and is otherwise guided over four rollers 24, 25, 26, 27.
  • the roller 24 can be designed here as a drive or drive roller and can be mounted in a stationary manner on the base plate 21, while the roller 25 is arranged displaceably on the base plate 21 as a tension roller.
  • the power belt 22 is otherwise still guided over the rollers 26 and 27, which act as pressure rollers.
  • the rollers 26 and 27 are freely rotatably mounted on levers 28 and 29, the levers 28 and 29 being arranged so as to be pivotable and lockable about their bearing points on the base plate 21 in order to make the wrap angle 9 (FIG. 2) adjustable in this way .
  • the wrap angle 9 can be changed.
  • the wrap angle 9 can also be influenced to a limited extent over the time in which the heating device 19 is active and heats the embossing die 15.
  • the band 12 is designed to be extremely flexible, the force band 22 serves to transmit a finely adjustable contact pressure during the embossing process.
  • This stamping process is explained using FIG. 2: After the workpiece 1 has come to a standstill in the receiving station 2 below the base plate 21, the rollers 7 and subsequently or at the same time the base plate 21 are lowered onto the workpiece 1 in the direction according to arrow 30, so that the relative position shown in FIG. 2 results .
  • the drives 4, 11, 14, 24 are activated synchronously, so that the surface of the workpiece 1 according to arrow 5, the hot stamping foil 6 according to arrow 3, the band 12 with the die 15 according to arrow 13 and the force band 22 likewise according to arrow 3 move together under surface contact, the actual stamp 15 running under the rollers 26 and 27 during the stamping process.
  • the heating device 19 is set into operation and coordinated with this temporal process during the wrap angle 9, the melting and pressing of the hot stamping foil 6 in accordance with the print image provided on the stamp surface 18 on the workpiece. This includes the wrap angle 10 for the cooling time.
  • the end of the cooling time or the angle 10 can be influenced, the geometric limits of the two wrap angles 9 and 10 also being influenced by the temperature Heating device 19 is determined.
  • the remaining hot stamping foil is removed from the surface of the workpiece 1 at the end of the wrap angle 10. Embossing has been carried out. It goes without saying that, during this embossing, the force band 22 was also also moved via the drive 24 with surface contact.
  • the drive 24 Since the power strip 22 is guided on a somewhat larger radius than the surface of the workpiece 1, the drive 24 must run somewhat faster than the drive 14 of the strip 12 in order to avoid a relative movement, and this in turn faster than the hot stamping foil 6 or the Surface of the workpiece 1.
  • the differences result solely from the different radii, because overall a common movement must be achieved without any relative movement of the parts and while maintaining surface contact.
  • the individual elements return to the basic position according to FIG. 1.
  • the embossed workpiece 1 is continued one cycle and a new workpiece 1 passes under the base plate 21 so that the embossing process can be repeated.

  • the rollers 26 and 27 are shown mounted directly on the base plate 21, although these could of course also be mounted on levers 28, 29, as shown in the embodiment of FIG. 1. Since the difficulty with this oval bottle is that the respective wrap angles 9 and 10 also change continuously with the movement of the surface of the bottle according to arrow 5, a special effort is required to at least approximately constant contact times and cooling times for the individual surface areas of the To achieve the surface of the workpiece 1.
  • One possibility is to accelerate or slow down the synchronous running of workpiece 1, stamping foil 6, stamping die 15 and force band 22 in the sense of changing the semiaxes of the oval cross section during the stamping of a bottle.
  • Another possibility is to give the rollers 7 and 26 and 27 a control movement in order to change the wrap angle during the embossing by such movements.
