Description

  • It is a device for removing from a substrate after proposed a film printing projecting film parts.
  • At the Foil printing, parts of a film on the surface of a Applied substrate. The job is done on the substrate by means of a film carrier provided with the film, which has a printing form with a given contact pressure and under the influence of heat on the Pressed material pressed becomes. In this case, the predetermined by the printing form areas firmly anchored the film in the substrate. Depending on the thickness and Deformability of the substrate, after contact pressure and printing form arises during film printing a more or less strong impression of transferred to the substrate Film layer. Will an embossing tool with Structure used, so can Parts of the printed image with a grid-like surface structure be provided. Furthermore, can Parts of the transferred film layer higher or higher lower than the structural surfaces. By means of the printing form, a relief can be embossed.
  • The Printing form ensures that only the desired ones Regions of the film are applied to the substrate. The remaining areas remain on the film carrier. They are used together with the film carrier after printing lifted off the substrate. To ensure a high quality print image, is a marginal sharpness with high precision in the range of 0.01 mm necessary. It needs a precisely defined Foil print image, which stands sharp on the substrate.
  • When disadvantageous proves that at the edges of the on the substrate transferred during the printing process Slide small film parts remain, which protrude from the substrate. These parts are also called baubles or foil particles. They adhere more or less loose, but process-related without fixed Anchoring at the edge areas of the foil print image. These slide parts take care of one low edge sharpness and for a poor quality print. Relevant parameters for training such protruding film parts are the nature of the film, their detachment behavior in Connection with the nature of the surface of the substrate, the Moment of force during film transfer as well as the temperature in the process. To get a good print, have to the protruding foliate parts in an additional step after Completing the printing process will be removed. This is done so far manually. It is therefore with a high expenditure of time and costs connected.
  • Of the Invention has for its object to provide a device available which is the machine removal of projecting film parts allow for a film print of the substrate. This is the removal the slide parts during carried out the transport of the printing material.
  • These The object is achieved by a device having the features of the claim 1 solved. The device is equipped with a brush roller equipped, which a brush trim having. After film printing, the film is equipped with the film Printing material relative to the brush roller transported. The distance between the rotational or longitudinal axis the brush roller and the transport distance of the printing substrate is smaller than the radius the brush roller or agrees with the radius of the brush roller. This ensures that that the brush trim touches the substrate. The brush roller is rotated, causing the brush trim with the surface of the substrate interacts. Due to the friction between the brush trim and the surface of the printing material, the projecting film parts at the edges of the Foil printing of the substrate solved. The foil print image anchored in the substrate is retained and will not be affected. The force that the Brush roll on applies the substrate, and the rotational speed of the brush roller can in dependence be adjusted by the film and the printing material.
  • The brush roll has a brush body, in which the brush trim is anchored. Advantageously, the brush body is an elongate cylindrical body whose longitudinal axis with the rotation axis of the brush roller coincides. The brush trim is radially outward from the brush body. This can be the brush trim from artificial or natural Bristles or other cylindrical or conical elements, which has a scraping or scouring effect on the surface of a Exercise substrate. The brush trim is specified such that the force on the substrate is sufficient is great to solve the protruding film parts, but without the To damage the substrate and the film transferred to the substrate.
  • Further the device is equipped with a suction device, which by means of the brush roller detached from the substrate Suction film parts. The suction device is located in the immediate vicinity Close to the brush roll, so that the film parts immediately after their detachment from taken up by the suction through the suction and transported away become. Another contamination of the substrate with the detached film parts is avoided.
  • The device ensures that the not firmly anchored to the substrate parts of the film be reliably removed and transported away after the process of film printing. This ensures an improvement and refinement of the edges of the film areas transferred to the printing substrate. A higher edge definition is achieved, resulting in a high-quality print image.
  • The inventive device can be integrated in a film printing device. She can as Additional unit to be installed in a film printing machine. So can the brush roller and the suction device after the printing tool in a film printing machine be arranged. The removal of the protruding film parts or film particles takes place while the transport of the substrate provided with the film.
  • To An advantageous embodiment of the invention is the device with a deflection roller for deflecting the printing material on the brush roller fitted. The guide roller is part of the transport route of the Printing material. In this case, the guide roller and the brush roller aligned parallel to each other. At the guide roller are the protruding film parts spread from the substrate. Thereby increases the distance between the individual projecting film parts. This favors the Interaction of the individual film parts with the brush roller and thus the removal of the film parts of the substrate.
  • To a further advantageous embodiment of the invention are the Deflection roller and the brush roller driven in the same direction to the rotation. This means that the direction of rotation of guide roller and brush roller is the same. In that area, in which the brush roller the guide roller closest comes, the movement is in reverse. Of the brush border moves against the transport direction of the substrate on the surface of the substrate along. This will change the interaction between the substrate and the brush trim reinforced and the release the projecting film parts of the substrate favors.
  • To a further advantageous embodiment of the invention is the Sum of half the diameter of a brush body of the brush roller and the length of the brush fitting larger than in the radial direction the distance between the longitudinal axis the brush roller and the longitudinal axis of the Deflecting. In the brush body of brush roll is the brush trim arranged. The sum of half the diameter of the brush roller and the radial length of brushing corresponds to the radius of the brush roller measured from the longitudinal axis the brush roller up to the longitudinal axis facing away Ends of the brush trim. As the radius of the brush roller is larger as the distance between the longitudinal axis the brush roller and the guide roller is an interaction between the brush roller and a printed on the guide roller transported substrate guaranteed.
  • To a further advantageous embodiment of the invention is the Extraction device equipped with at least one suction nozzle. The suction nozzle points an elongated one Shape up and stretch across the entire brush roller. This ensures that that the suction device over the entire width of the brush roller Can accommodate film parts.
  • To a further advantageous embodiment of the invention is the suction nozzle arranged in the tangential plane of the guide roller or the brush roller. It is exploited that the dissolved of the substrate foil particles due to the brush roller lent momentum in the tangential plane of the guide roller remove. The suction nozzle is thus aligned so that the film particles when loosening Already move the substrate in their direction.
  • To a further advantageous embodiment of the invention is the brush border anti-electrostatic. This will prevent the brush trim can charge electrostatically. The charge of brush fill would do it to lead, that the film particles and possibly other impurities the brushing be liable. This would be the Process of removing the protruding film parts of the substrate affect.
  • To a further advantageous embodiment of the invention the brush trim from a natural one or artificial produced material.
  • The inventive device is characterized by the fact that the printing material relative to the surface of a brush roll is transported to protruding film parts of the substrate to solve, and that the detached one Folienile picked up by a suction and transported away become.
  • To an advantageous embodiment of the substrate via a Transported deflecting roller. Advantageously, the deflection roller in the same direction as the brush roller driven for rotation.
  • Further Advantages and advantageous embodiments of the invention are the subsequent description, the drawings and the claims.
