Definitions

  • the invention relates to a device for the dry printing of a workpiece using a hot stamping foil and a stamp and using heat, pressure and time, in which the workpiece and the stamp moves relative to one another, with the hot stamping foil being held in contact, with intermediate clamping Heat is transferred and moved away again, the hot stamping foil being stuck onto the workpiece in accordance with the stamp and being detached from the workpiece after a cooling time with the exception of the printed image, with a receiving station for the workpiece, a cyclically operating feed device for the hot stamping foil and a heating device for the made of elastically preformable material and having a stamp body.
  • the invention can be used in particular in the printing of flexible hollow bodies made of plastic or with a plastic layer arranged on their surface using the hot stamping foil printing method.
  • blown plastic bottles especially for the cosmetics industry - regardless of the cross-section - can be printed. It does not matter how the surface of the workpiece to be printed is designed in detail; this surface can in particular be flat, convex-round, convex-oval or also concave.
  • 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 of the workpiece to be printed.
  • the hot stamping foil itself consists of a carrier tape, a separating layer, expediently a protective lacquer, the actual color layer, which often contains an additional metal layer, and the adhesive or
  • connection layer to the plastic surface to be printed All other layers apart from the carrier tape are applied to the surface to be printed during the printing process and, after appropriate cooling, are torn off from the hot stamping film or the carrier tape where they were glued or connected to the surface to be printed.
  • a device of the type described at the outset is known from DE-PS 34 21 029, in which the two essential previous printing processes, namely the lifting process on the one hand and the rolling process on the other hand, are described.
  • DE-PS 34 21 029 in turn now shows a method for dry printing, in which the embossing stamp is brought into contact with the workpiece by continuous application over the entire stamp surface and the embossing stamp, at least in the region of the stamp surface, corresponds to the shape of the workpiece Is brought into shape.
  • the embossing stamp consists of a base body, for. B. a thin metal strip, and a stamp body such. B. from a rubber mixture which has a stamp surface corresponding to the desired print image. The heat is generated in the base body and passes through the stamp body through heat conduction into the stamp surface, where it is transferred to the hot stamping foil and the surface of the workpiece to be printed.
  • the workpieces to be printed can only be produced with tolerances, that is to say in certain tolerance bands, with regard to the formation of their surface to be printed.
  • tolerances that is to say in certain tolerance bands
  • the occurrence of unevenness, sink marks in two dimensions, etc. cannot be avoided.
  • the hot stamping foil does not have the necessary contact with the surface to be printed. This can be counteracted by pressing harder from the back of the workpiece, for example by inflating a bottle to be printed.
  • Another possibility is to make the stamp thicker. Both measures can also be used in combination; however, they prove to be disadvantageous both individually and in combination.
  • the invention has for its object to provide a device of the type described above, with the workpieces with geometric deviations in the surface, for example with sink marks, bumps and / or wall thickness differences, especially with flexible hollow bodies, with good service life clean and with great performance can be printed using the hot stamping foil printing process, whereby the sensitive embossing stamp is subjected to as little thermal and mechanical stress as possible.
  • the stamp body is so thin-walled that when it is placed on the workpiece to be printed it rests elastically deforming on the surface thereof, that the Stamp body on its side facing away from the stamp surface has a positive force transmission relief which corresponds to or is similar to the stamp surface, and that the stamp body on the side facing away from the stamp surface is assigned an elastic pressure pad for the elastic deformation of the stamp body.
  • the stamp body is particularly thin-walled, in such a way that it can elastically deform locally within its surface, so that there is the possibility of following the unevenness and incidence on the workpiece to be printed within a flat surface, for example.
  • a positive force transmission relief is provided on the back of the stamp body, that is to say points which deliberately serve to transmit forces to the stamp body and the stamp surface. These are not particularly large forces, but first and foremost to apply forces that are as small as possible locally, but which are sufficient to produce a clean print image. The relatively small forces also have an advantageous effect with regard to the service life of the embossing stamp and thus also of the stamp body, because the elastic material is not mechanically stressed to this extent. The resetting behavior of the elastic material of the stamp body as well as other components of the stamp is not damaged.
  • This power transmission relief is positive, ie represents a positive. It has the same or similar appearance to the right side as the printed image on the workpiece which is to be produced.
  • the contact surface of the power transmission relief can protrude from the rear surface of the stamp body or can also be enclosed flush in this surface. It is also possible to choose the width dimensions of the contact surface differently from the design of the stamp surface on the stamp body. However, both must always correspond to each other, ie there must be power transmission from the back to the front from the transfer relief to the stamp area.
  • an elastic pressure pad for the elastic deformation of the stamp body is arranged or in any case provided for action, so that with the help of this pressure pad the thin stamp body can be elastically deformed locally, so that sink marks and unevenness are bridged, specifically without the stamp body being loaded mechanically and thermally more than necessary.
  • the ways in which the forces are conducted are very short.
  • the large, thin-walled body of the stamp has an advantageous effect on great flexibility and thus in compensating for the imperfections, sink marks and differences in wall thickness, when working with the smallest pressures in the pressure pad.
  • the set-up time of a printing press which is equipped with the new device, is considerably shortened because the stamp adapts better and to a greater extent to the tolerances. After all, the energy consumption is considerably reduced.
  • the thermal energy to be used in hot stamping foil printing is approximately 1/20 to 1/30 of the thermal energy previously required.
  • the elevated points on the stamp surface of the stamping die are pressed against the workpiece to be printed with less force than previously in the region of the unevenness of the workpiece, this pressing being done with very low pressure by the pressure pad. This avoids pinching with the material of the stamp body, so that there are no line thickness differences due to pinching.
  • the pressure pad only has to be pretensioned to such an extent that the necessary force is generated in order to bring the raised points in the area of the stamp surface into contact with the unevenness on the surface of the workpiece to be printed, matched to the elasticity of the stamp.
  • the heating device can be provided on or in the stamp body and can be arranged locally in accordance with the printed image, and that the heating device also forms the power transmission relief.
  • the heating device is designed as a printed circuit board, the individual conductors being guided and arranged such that they are at least similar to the printed image. Since the material of the heating device is inelastic because it consists of metal, hard points thus arise in the elastic material of the stamp body, namely the power transmission relief, which is effectively present without the after Back protruding raised areas are present. Since the heating device is no longer provided on the base body of the die, but directly on or in the die body, extremely small paths are created in connection with the small wall thickness of the die body, via which the heat must be transported by heat conduction.
  • the heating device no longer extends flatly over the base body of the embossing stamp, but is arranged locally in accordance with the printed image, so that, as it were, each raised point of the stamp surface, which forms the printed image as a whole, is heated individually.
  • the stamp body made of elastically deformable material is provided on one side of a carrier body and the force transmission relief made of elastically deformable material is provided on the other side of the carrier body.
  • the carrier body itself can be a metal strip, in particular for handling purposes, or else a rubber band.
  • the locations of the power transmission relief project beyond the surface on the back of the stamp body, so that in this way they enable the transmission of minimal but sufficiently large forces by contact with the pressure pad.
  • the force transmission relief can be designed, in particular, on its contact surface to the pressure pad similarly, namely, the same, smaller or larger than the stamp surface of the stamp body.
  • the power transmission relief consists of a conductor track made of metal, it is expedient that the guide of the conductor track is ultimately smaller than the outline of the stamp surface of the stamp body.
  • the power transmission relief consists of raised points made of elastically deformable material, an enlargement compared to the stamp surface of the stamp body can be useful here, ie the positive on the back The resulting letters and lines are larger in width and height than the letters that form the printed image in the stamp area.
  • the heating device can be provided in the stamp body between the relief having the stamp surface and the power transmission relief and at the same time form the carrier body, so that the stamp body can be handled simultaneously with the aid of the carrier body or the heating device, i. H. can be held and guided in a machine.
  • the carrier body has a double function.
  • the stamp body can be provided with the power transmission relief in the form of a reciprocating plate or a rotating belt.
  • a reciprocating drive on a belt is also possible.
  • the training in detail depends on the desired service life, the speed at which printing is to be carried out, etc.
  • the device according to the invention makes it possible to create hot stamping stations which can also be used as work stations in combination with screen printing stations, because with the device according to the invention the working speed can be increased during hot stamping so that it reaches the working speed of the screen printing stations, so that both different printing stations can ultimately be operated in a work line side by side or in succession without interference.
  • the heating device may be provided outside the stamp body and for the heat to be transferred directly to the stamp surface.
  • the heat transfer can be generated, for example, by an infrared source.
  • the heat is applied directly to the stamp surface without contact or with contact via an intermediate roller or the like, so that it ultimately does not have to travel any further in the stamp body during the subsequent contact during hot stamping foil printing, but is directly available at the printing point.
  • a screen can be provided between the heating device and the stamp surface of the stamp body, the heating device and / or the screen being arranged to be stationary or adjustable.
  • Such an aperture allows, for example in connection with an infrared heating source, to transfer heat specifically to the stamp surface and to leave the neighboring surfaces of the stamp body, which can act as a support surface, comparatively colder, so that printing errors are already impossible in this way .
  • the screen can also be cooled, particularly when it is fixed in place, so that it does not itself become a radiant source due to the infrared radiation.
  • the hardness of the pressure pad should be adapted to the hardness of the material of the stamp body, in such a way that the elastic deformation of the stamp body is possible. If the stamp body is made particularly soft, the pressure pad is also made particularly soft. If the stamp body has a greater hardness, that must also Pressure pads will be able to overcome this greater hardness. Of course, it makes sense to choose the design that is as soft as possible, because it is not a question of generating a high contact pressure of the stamp surface against the hot stamping foil and thus of the surface of the workpiece to be printed, but only of the elastic, local deformation of the stamp body. This deformation should be such that, despite this deformation of the stamp body, all locations on the stamp surface are pressed against the hot stamping foil with approximately the same contact pressure.
  • the force transmission relief can be formed on its contact surface equal to the stamp surface of the stamp body and a distribution rubber band can be provided between the contact surface and the pressure pad.
  • This rubber band protects the pressure-sensitive pressure pad against the force transmission relief being pressed into the material of the pressure pad and thus prevents damage to the pressure pad.
  • the distribution rubber band supports the forces transmitted via it on the pressure pad over a larger area, which is useful for increasing the service life.
  • a hydraulic or pneumatic cushion, a cushion made of foam or the like can be provided as the pressure cushion.
  • a pneumatically inflatable bellows also fulfills its function here.
  • An embodiment of the pressure pad as a tampon is also possible.
  • a printed circuit board with a carrier film and a resistance metal track located thereon can be provided as the heating device, in accordance with the design and arrangement of the printed image.
  • several resistance metal tracks can be arranged aucti.
  • the carrier film only has the task of receiving and holding the resistance metal track.
  • Both the carrier film as well the resistance metal track are extremely thin and can be arranged directly behind the stamp body, such that the resistance metal track is facing the stamp body. It is of course also possible to mold the circuit board into the material of the stamp body. In this case, there are particularly short paths of heat conduction.
  • a heat insulation layer made of elastic material can be provided between the carrier foil of the printed circuit board and the pressure pad.
  • This layer can be part of the pressure pad or an independent layer made of a material that differs from that of the pressure pad.
  • the stamp body itself can be designed in some areas as a support mask, while in other areas it has the stamp surface. These two areas mentioned can also be made of different materials, for example.
  • the stamp body having the stamp surface expediently consists of a material mixture which is a good heat conductor. In the area of the support mask, a material can be used which is poorly heat-conducting. In connection with the locally acting heating device, it is achieved that the required high temperature for embossing is only established where the stamp body has the stamp surface, while the temperature on the parts forming the support mask is lower, so that there is a detachment of the ink layer not done by the stamping foil. However, it is also possible to design the areas forming the support mask from a material which is a good conductor of heat, in which case these areas must then be cooled.
  • the pressure pad can be permanently connected to the stamp body, so that the stamping die is, as it were, in one piece. Split training is also possible although this is generally not recommended.
  • the connection between the pressure pad and the stamp body enables the spring properties of the pressure pad to be matched precisely to the elasticity of the stamp body.
  • the pressure pad can in particular have a greater wall thickness than the stamp body, so that local compressions of the pressure pad do not manifest themselves or only in a change in the contact pressure.
  • the pressure pad can also consist of heat-insulating material and thus take over the function of the heat insulation layer. A separate layer of thermal insulation is thus eliminated.
  • the pressure pad can be designed to generate a pressure of approximately 100 g / cm2. This extremely low contact pressure makes it clear that it is not important to use high contact pressures for hot stamping foil printing; it is only necessary to achieve a good surface contact of the stamp surface even on the unevenness of the surface of the workpiece to be printed.
  • the pressure pad primarily serves for the elastic deformation of the stamp body and the force to be applied by it is matched to this. In addition, it also ensures contact with the hot stamping foil or the contact of the hot stamping foil with the workpiece surface.
  • the embossing stamp 1 has a stamp body 2, which consists of a rubber mixture and which bears a stamp surface 3 formed by raised spots, which in negative form corresponds to the printed image, that is to say the image appearing on the workpiece to be printed.
  • Other areas of the stamp body 2 or the stamp surface 3 can form a support mask 4.
  • a heating device 5 is arranged, which is essentially designed as a printed circuit board and can thus have a carrier film 6 on which one or more Resistance metal tracks 7 are arranged, in relation to the raised positions of the stamp surface 3, which must be heated accordingly.
  • the comparatively hard and thus inelastic points of the resistance metal tracks 7 form a positive, recessed force transmission relief which serves to transmit small but necessary forces from the pressure pad into the stamp surface and thus onto the workpiece.
  • a pressure pad 8 made of compensating, resilient material, for example made of foamed plastic, is provided on the back of the stamp body 2 thus formed.
  • the spring hardness of the pressure pad 8 is matched to the spring hardness of the material of the stamp body 2.
  • a heat insulation layer 9 can be arranged between the pressure pad 8 and the stamp body 2 with the heating device 5. This heat insulation layer 9 may also be absent if the material of the pressure pad 8 itself provides sufficient heat insulation. It can be seen from Figure 1 that the stamp body 2 locally heated individually is there, where the stamp surface 3 is located. The areas of the support mask 4, however, are not heated. These areas of the support mask 4 will therefore assume a lower temperature on the surface than the stamp surface 3.
  • FIG. 2 shows a section of an embossing stamp 1, which has the structure shown in FIG. 1, at the moment of contact via a hot stamping foil 10 on the surface 11 of a workpiece 12 to be printed.
  • the conditions are exaggerated to solve the problem of sink marks and to clarify irregularities in the course of the surface 11 of the workpiece 12.
  • This surface 11 may have bumps 13, sink marks or the like as they occur in a surface which is in itself flat.
  • a good print image on the surface 11 of the workpiece 12 is generated when, despite the unevenness 13, the raised areas of the stamp body, ie the stamp surface 3, come into contact with the corresponding areas on the surface 11.
  • the widths 14 of the raised areas of the stamp surface 3, for example the font thickness, must not undergo any changes when compensating for the unevenness 13, that is to say in particular they must not be squeezed locally or, on the other hand, have insufficient contact with the hot stamping foil 10 and the surface 11. Too little contact would lead to defects in the printed image. Excessive contact leads to disturbingly deep impressions in the surface 11. It can also be seen from FIG. 2 that the pressure pad 8 per se only has to exert a comparatively low pressure force, in such a way that the stamp body 2, which itself is very thin , is deformed elastically to the required extent.
  • the die 1 can be attached to a lifting head 15, which is only indicated schematically here, in accordance with a double arrow 16, while the workpiece 12 is supported on a table 17.

  • the entire stamp body can also be made from a continuous piece of material.
  • the local assignment of the heating device makes one part of the surface of the stamp body 2 a stamp surface 3 and the other part a support mask 4.
  • FIG. 5 shows the heating device 5 belonging to the exemplary embodiment of FIGS.
