Definitions

  • the present invention relates to a device for partially embossing sealed blanks and to a method for partially embossing sealed blanks.
  • Food containers are often sealed today with sealable lids. This is especially true for foods that are consumed directly from the container.
  • the containers are usually formed directly in a device, filled with the intended product and then sealed with a sealing plate.
  • prefabricated containers are filled in a machine and sealed with a sealing plate.
  • Such devices are known as so-called "fill-seal" machines (FS machines).
  • FS machines fill-seal machines
  • the sealing plates required for the closure of the container are usually prefabricated sealing plates, which are manufactured in large quantities and stored or transported in stacks. These sealing boards are often made of aluminum or a laminate comprising an aluminum layer.
  • the sealed blanks are supplied to the food-filling machine by means of a feeder, for example, the above-mentioned fill-seal machines and sealed sealed directly on the edge of the filled container.
  • the often additionally printed and stamped according to the contours of the container sealing plates are stacked. Since the sealing plates are transported and delivered in stacks, the sealing plates must be unstacked again by means of the feed device and fed individually to a filled container. The stacking of the flat and smooth sealing boards, however, causes them to stick together with considerable adhesion in the stack (glass plate effect). However, the orderly unstacking of the sealing plates is difficult to control and it is not guaranteed that the sealing plates individually destacked and each supplied to a container or sealed. To ensure the unstacking of individual sealing plates, it is known, for example, to emboss the sealing plates.
  • EP 0 960 024 is a method for only partial embossing of lids known.
  • the partial embossing of the lid is achieved by means of reading marks on the foil material, from which material the lids are punched out. These reading marks allow the correct positioning between the printed parts of the films and the parts of the film or embossing tools to be embossed.
  • EP 1 790 470 a method for the partial embossing of lids is described, wherein the geometric position of the embossing tool is adjustable to the film web and the partial embossing is introduced only every second lid.
  • An object of the present invention is to provide an apparatus and a method for producing partially embossed sealing boards, which can be processed easily and trouble-free.
  • the embossing tool in turn comprises a die and a male. It is on the patrix the desired Tiefzugkontur or the three-dimensional relief imaged by mechanical methods. And indeed, the patrix has the three-dimensional relief in a raised and mirror-image form. The counterpart of the patrix, the die or stamp, has the three-dimensional relief in laterally correct and recessed form.
  • On the contoured side of the male part three-dimensional elements are arranged in an outer area and in a central area. The male part is rotatably supported in its spatial position about an axis A substantially perpendicular to the film strip.
  • embossing and punching tool are combined in a tool.
  • the film web is gradually shifted in the transport direction or machine direction of the device.
  • the embossing tool arranged in front of the punching tool generates the desired contour by means of a lifting movement by deep drawing in the sealing plate, before the next lifting movement takes place, the foil strip is moved in the direction of transport via corresponding transport means such that the foil strip or the now partially embossed sealing plate touches the position of the punching tool comes to rest, where it is punched out of the foil strip during the next stroke movement.
  • the male of the embossing tool is rotatably mounted about an axis A, which is substantially perpendicular to the film strip, can be achieved by a simple rotation of the male by an angle ⁇ about the axis A, that no two successive sealing blanks, after punching in a stack to lie on each other, have a congruent imprint.
  • ⁇ about the axis A
  • the three-dimensional elements are arranged randomly in the outer and in the central region. Particularly preferably, the three-dimensional elements are arranged randomly in the outer region.
  • the three-dimensional elements in the outer region and in the central region of the male are arranged on circular lines, preferably at regular intervals.
  • the three-dimensional elements can have different shapes.
  • it may be cylindrical, preferably circular cylindrical, projections which extend substantially perpendicularly away from the surface of the male.
  • the individual three-dimensional elements have a different height. That is, the male part has three-dimensional elements, part of which has a first height, while the other three-dimensional elements have a second height different from the first one. It is also possible that there are even more groups of three-dimensional elements having, for example, a third and a fourth height.
  • the male part is rotatably supported by an angle ⁇ .
  • the angle ⁇ corresponds to the midpoint angle of a circular sector, which is defined by two adjacent three-dimensional elements.
  • the angle ⁇ is in a preferred embodiment in a range of 2 ° to 90 °, more preferably in a range of 3 ° to 45 °, and most preferably in a range of 4 ° to 15 °.
  • the three-dimensional elements can be designed differently as already stated and, for example, have different heights.
  • the three-dimensional elements have a height in the range of two to five times the thickness of the film strip. Particularly preferably, they have a height in the range of three to four times the thickness of the film strip. Again, all three-dimensional elements may have the same height within the specified ranges, or the three-dimensional elements may have two or more different heights. Three-dimensional elements of different heights further reduce the effect of stacking sealed platelets sticking together.
  • a typical thickness of films or film tapes used for the production of sealing plates according to the invention is in the range from 20 ⁇ m to 50 ⁇ m, preferably in a range from 24 ⁇ m to 40 ⁇ m and particularly preferably in the range from 30 ⁇ m to 36 ⁇ m.
  • Two examples of typical thicknesses for the films used are 25 ⁇ m and 35 ⁇ m.
  • the most preferred ranges for the height of the three-dimensional elements can be determined, which corresponds to three to four times the thickness of the film strip used.
  • the height of the three-dimensional elements is in the range of 60 ⁇ m to 200 ⁇ m, preferably in the range of 72 ⁇ m to 160 ⁇ m and more preferably in the range of 90 ⁇ m to 144 ⁇ m. Accordingly, the areas corresponding to two to five times the film thickness can be determined for the height of the three-dimensional elements.
  • the height of a three-dimensional element is measured from the film surface to the tip or end face of a three-dimensional element.
  • the outer borders Three-dimensional elements area of the male directly to the edge of the male. Furthermore, the outer area is arranged concentrically to the central area. The central area also has three-dimensional elements at least on its outer periphery.
  • the die and the male of the embossing tool are adapted in their contour or their circumference of those of the sealing plate. The same applies to the contour of the punching tool.
  • the die and the male of the embossing tool have a circular contour or a circular circumference.
  • embossing tool and the punching tool are arranged adjacent and both tools are operable synchronously.
  • the inventive method for producing partially embossed sealing plates for containers, in particular for food, is carried out on a device described above.
  • a continuous film strip of the device is fed via rollers.
  • the film strip is preferably already pre-printed and then wound up on a roll.
  • the continuous foil strip with the previously printed sealing plates is fed to the embossing tool.
  • the transport of the film strip is gradual and between the feed steps, the foil strip is stationary.
  • the partial embossing of the sealing plate is produced by means of a lifting movement by the embossing tool or its male part.
  • the foil strip or the now partially embossed sealing plate is moved forward in the transport direction and positioned over the punching tool.
  • the partially embossed sealing plate is punched out and stacked via a collecting channel.
  • the male of the embossing tool becomes a substantially perpendicular to the foil strip standing axis A by at least one angle ⁇ twisted.
  • the angle ⁇ is in a preferred embodiment in a range of 2 ° to 90 °, more preferably in a range of 3 ° to 45 ° and most preferably in a range of 4 ° to 15 °.
  • the angle ⁇ 4.39 °.
  • the male is thus rotated between two strokes by the rotation angle of 4.39 °.
  • the angle ⁇ is small, so that the rotation of the male in the process does not speed limiting.
  • the male is rotated back after an initial rotation by the angle ⁇ between two strokes by an angle ⁇ in the opposite direction of rotation.
  • FIG. 1 shows a plan view of a male part 1 of a stamping tool.
  • the male part 1 is rotatably supported about an axis A and has an outer region 3 and a central region 5.
  • Both the outer region 3 and the central region 5 comprise three-dimensional elements 7.
  • the three-dimensional elements 7 are arranged in the outer region 3 on two concentric circular lines.
  • the central region 5 also has three-dimensional elements 7 arranged on its circular circumference. However, the region lying between the outer region 3 and the central region 5 is free of three-dimensional elements 7. Shown below is the contour of the sealing plate 9, which extends virtually in its periphery to the edge of the male part 1.
  • FIG. 2 shows the male 1 FIG. 1 in two different rotational positions.
  • the male part 1 was rotated by the first rotational position by an angle ⁇ in the two rotational position.
  • the arranged in the outer region 3 of the male part 1 on two concentric circular lines three-dimensional elements 7 are arranged offset on the two circular lines, so that after a rotation of the male part 1 by an angle ⁇ about the standing substantially perpendicular to the male axis A each have a three-dimensional element 7 of the inner concentric circle line to lie on the angular position, on which, prior to rotation, a three-dimensional element 7 of the outer concentric Circular line was and vice versa.
  • FIG. 3 shows a cross section through a section of a male part 1 with three-dimensional elements 7, 7 'and 7 "with different heights.
