Definitions

  • the invention relates to a method and a device with which perforated films can be produced.
  • films such as plastic films, metal foils or plastic-metal composite films are provided with a number of holes, the holes are often to have only a small hole diameter.
  • various processes are known for the production of perforated films.
  • the DE 299 08 254 U1 discloses the production of perforated films by means of two counter-rotating rollers, between which the film to be perforated is passed.
  • the rollers are provided with cutting teeth which form short tears in the film passing between the rollers, which are more or less widened by the wedge shape of the teeth.
  • the JP 2001 001 007 A discloses a method for producing a perforated film by means of a profile roller and an elastic pad.
  • the metal foil to be perforated is placed on the elastic base over which the profiled roller is rolled.
  • portions of the elastic base penetrate into recesses of the roller and separate film sections from the film. This is a punching process.
  • thin sheets for example, not too thin metal foils can be punched by punch, each punch then on the other side of the foil an insert is associated with a cutting opening, which forms a cutting gap with the punch.
  • This method reaches its limits with decreasing sheet metal or film thickness, because the cutting gaps must be narrower than the film thickness. With thin films, it is hardly possible to achieve sufficient free-standing quantities. For very small hole diameters of e.g. 100 microns is also difficult to ensure that all punches (for example, several hundred or several thousand) find in the associated holes of the insert.
  • first holes are produced in the film, for example by the film being pierced at several points. Subsequently, the edges of the resulting holes of the film are pressed. This measure ensures that standing away from the edges of the hole short Folienzipfel or lobes do not close the resulting hole again. Rather, these lobes or flaps are deformed so that they, even if they relax elastically something, the resulting hole can not close.
  • This method is suitable both for metal foils and plastic films or composite films, such as metallized plastic films or metal foils with plastic coating, paper with metal coating, paper with plastic coating or coated films made of different materials.
  • the film thickness can vary within wide limits.
  • Method is particularly suitable for processing films with a thickness of a few tens of micrometers, for example 50 microns. It can holes are introduced into the film whose diameter is smaller or larger than the film diameter. For example, holes with a diameter of 100 ⁇ m can be inserted into an aluminum foil with a thickness of 50 ⁇ m. While the hole is first opened in the step of piercing the film, it is fixed in the step of pressing the edge of the hole concerned. The hole shape can be maintained or changed depending on the process. The hole shape can be largely determined or left to random process influences.
  • the generated holes may be substantially round or polygonal or irregularly shaped.
  • the hole shape may be influenced by the cross-sectional shape of a needle-like tool for piercing the film and / or, if it has no circular cross-section, by the orientation of the cross section of the tool to the film transport direction.
  • the shape of the hole can be influenced by the way the hole edges are pressed.
  • the holes are preferably made with needle-like tools having a tip and a conically flared portion. After the tip has penetrated through the preferably held resting film, the tool is axially moved further, whereby the resulting hole is widened. The material displaced thereby forms lobes or lobes that stand away from the film. When pressing these tabs or lobes are pressed against the back of the film or compressed into it. The resulting hole edges are relatively smooth. They essentially exist from drawn into the hole, former surface areas of the film. Also, the film back is largely smooth by pressing.
  • Another object of the invention is to provide a device for producing perforated films.
  • a corresponding device has a means for piercing the film and a means for preferably stationary or, if necessary, moving storage of the film during the piercing operation. Furthermore, a means for pressing the edges of the holes produced is provided. The means for pressing the edges of the holes produced allows a fixation of the holes produced in the stitch process, so that they can not close unintentionally. They are fixed in their shape and in diameter.
  • the means for piercing the film is preferably in at least one tool having an elongated working part with a tip, starting from which increases the cross section of the working part.
  • the working part is formed at least partially or conically as a whole.
  • the diameter increase of the working part away from the tip may be linear, progressive or degressive or degressive-progressive degressive (s-shaped) or otherwise formed.
  • the tip of the working part may be a point point or a cutting edge. In the case of a point tip, the tip is formed by a sphere portion or similarly shaped surface area of very small radius.
  • the working part ends in a straight or curved edge, which creates a small cut on the film during insertion, which is widened by the working part.
  • the tool can be used for punching a linear axial back and forth to carry out walking movement. It is also possible to attach the tool or several tools to a rotating machine element, for example a roller, in order to perforate a passing film.
  • a support means is then not necessary for the film. As support means can serve as an air cushion, for example.
  • the position of the resulting by the insertion of the tools on the film tabs or lobes can be set as it favorable for the subsequent compression process is to push the rag or tail on the back of the film, but not in the tap hole.
  • the working part of the tool can have a circular cross section, a knife cross section, a polygonal cross section or another cross section. Knife and polygon cross-section allow the targeted determination of the positions of the first edge of the edge of the hole or flap.
  • a knife cross-section is, for example, a slender triangular cross-section (two corners and edges bent away from each other) or a triangular or polygonal cross-section with at least one very acute angle (for example a narrow rhombus).
  • the film is placed on the means for storing the film when piercing, for example, a support table.
  • This is preferably provided with openings into which the needles or other tools can enter.
  • These openings preferably have a diameter which is significantly greater than the diameter of the working part associated with the relevant opening. The diameter is preferably so large that no cutting gap is created.
  • the annular space between the working part and the wall of the opening has a width which is greater than the film thickness to prevent pinching the pierced in the opening hole edges.
  • a transport device In order to move the film continuously or in accordance with the cycle of the piercing movement of the needle-like tools in a stepwise manner, a transport device is preferably provided.
  • the transport device can at the same time form the means for pressing the edges of the holes produced in the unit.
  • two rollers which progressively convey the film and between which the film passes, can simultaneously cause the edges of the holes to be pressed.
  • jaws that squeeze the film can periodically clamp and progressively promote the film.
  • FIG. 1 schematically illustrates a device 1 which serves for perforating a film 2, which is guided through the device 1 as a film web.
  • the film 2 is e.g. wound on a bale 3, which is supported by a take-off device 4 and, if necessary, selectively driven to rotate.
  • the take-off device 4 can serve as a transport device for the stepwise movement of the film 2.
  • grippers or rollers may be provided which promote the film 2 gradually.
  • To the device 1 includes a means 5 for piercing the film 2.
  • To the means 5 in the present embodiment includes a support means in the form of a lower tool 6. This is designed as a perforated plate over the preferably flat top slides the film 2. The upper side of the perforated plate forms a support surface 7 for the film 2.
  • To the means 5 further includes an upper tool 8 with a tool guide plate 9 preferably with a flat bottom.
  • the tool guide plate 9 forms a gap with the support surface 7.
  • openings 10 are formed, which are in the lower tool 6 formed openings 11 opposite.
  • the diameters of the openings 10, 11 may be the same or different from each other.
  • the upper tool 8 further comprises a head support plate 12 in which heads 13 are held by needle-like tools 14 for piercing the film.
  • the tools 14 have a cylindrical shaft 15, for example, which protrudes into the openings 10 and is guided in a sliding manner. From the shaft 15, a working part 16 extends away, whose Preferably, the diameter is substantially smaller than the diameter of the opening 11.
  • the working part 16 is preferably a straight portion which extends longitudinally to the shaft 15 and ends at a tip 18 via a conical portion 17 ( Figure 2).
  • the head support plate 12 and the tool guide plate 9 are, as indicated in Figure 1, for example, mounted movably with respect to each other, the tool holder plate 9 is resiliently biased against a stop of the head support plate 12 away.
  • the head support plate 12 is connected to a not further illustrated drive which is adapted to give it a reciprocating motion, as indicated in Figure 1 by an arrow. The stroke of the movement is so great that, on the one hand, the tool guide plate 9 can be lifted off the foil and, on the other hand, the working parts 16 of the tools 14 can be stung through the foil 2.
  • the device 1 further includes a means 19 for pressing the film 2 for fixing holes produced.
  • this means 19 is formed by a fixed element 20 and a movably arranged element 21, which preferably have in each case flat pressure surfaces 22, 23 on the sides facing each other.

  • both elements 20, 21 can not only to each other and away from each other but additionally in the direction of the film 2 are oscillated back and forth to promote the film 2 gradually.
  • the device 1 is used, for example, for perforating plastic or metal foils, for example aluminum foils or for perforating composite foils, which consist of plastic as well as of metal or else of other materials. Preferably, it serves to perforate films whose material is plastically deformable.
  • the top plate 2 holds corresponding tools 14 in several rows, which preferably extend over the entire width of the film 2 or at least over the width of the area to be perforated.
  • the tools 14 of the individual rows may be offset from each other or arranged in a different pattern.
