Definitions

  • packing strips preferably of so-called push-through packs, which consist of a film strand made of a well for receiving tablets, coated tablets or the like. containing the bottom film web and a cover film closing the cups and connected to the bottom film web by sealing, it is of great importance that the individual desired packing units are punched out in such a way that little or no waste is produced. This is called waste-free punching cut, which is performed so that when cutting the film webs, the rear edge of a packing strip corresponds to the front edge of the following packing strip. There is therefore no waste between the individual packaging strips.
  • Another promotion that is placed on such packing strips is that the corners of the packing strips must be rounded. This is very important for the further processing of the packaging strips, since otherwise difficulties in inserting the packaging strips into folding boxes or the like. surrender. Furthermore, packs with non-rounded corners would pose a risk of injury both for the processor and in particular for the end user.
  • JP patent application 55/45360 JP patent application 55/45360 to proceed during the production of the packing strips in such a way that the corners in the conveying direction at the front have a different radius than the corners at the rear in the conveying direction.
  • this should avoid the sharp protrusion which arises when the circular lines with the same radii intersect when the circular lines intersect.
  • FIG. 4 of the aforementioned Japanese patent application it has been shown that a complete elimination of sharp protrusions cannot be achieved with this procedure, there is only a weakening of the sharp protrusions produced with the previously known procedure.
  • packaging strips which have rounded corners with different radii are not popular with the pharmaceutical industry since, apart from the uneven external appearance, they can cause difficulties in further processing, in particular when cartoning.
  • a method and a punching tool for producing packing strips that have rounded corners with the same radii would now be desirable to be punched out without waste. who can, can be processed without problems and pose no risk of injury.
  • the method according to the invention with the characterizing features of the main claim has the particular advantage that no sharp, hook-shaped projections occur on the edges of the packing strips when punching out packing strips without waste.
  • the die of the corresponding punching tool has rounded corners with the same radii.
  • the arrangement is such that the rounded corners at the front in the direction of movement of the packing strips each consist of two circular lines with the same radius, which are connected to one another by a tangent.
  • these packaging strips can be cartoned without difficulty. There is no longer any risk of injury due to the corner design according to the invention.
  • FIG. 7 shows a section through the punching tool
  • FIG. 8 shows the film webs from which the packing strips are punched out, in particular a packing strip which has just been punched out, .
  • Fig. 9 on an enlarged scale the section designated X in Fig. 8.
  • Figures 1 and 2 show packing strips 11 and 12, which arise in the conventional procedure when the foil webs to be punched out are offset in the feed direction.
  • the packing strip 11 shown in FIG. 1 Most frequently, however, a packing strip 12 with hook-like projections 13, as shown in FIG. 2, is produced by the known method.
  • a packing strip 14 according to FIG. 3 is generated if, in addition to the feed offset, there is also a lateral offset of the corresponding film webs.
  • FIGS. 4, 5 and 6 show packing strips 15, 16 and 17 which have been produced under the same conditions as the packing strips 11, 12 and 14 shown with FIGS. 1, 2 and 3, but according to the method according to the invention. It can be seen that there are no annoying, more or less sharp projections. As can be seen from the packing strip 17 shown in FIG. 6, this is even the case when there is a double offset of the film webs - feed and lateral offset. In addition to the good external appearance of the packing strips 15, 16 and 17 shown with FIGS. 4, 5 and 6, these packs Processing strips without any problems and pose no risk of injury to processors or end users.
  • the punching tool 18 shown in FIG. 7 is used to generate the packing strips 15, 16 and 17.
  • the course of the punching line of the longitudinal edge 19 of the punching tool 18 is chosen such that even with a film offset 20, as indicated in FIGS Punching line 19 of the punch 18 cuts the edge 21 of the previously punched-out packing strip in such a way that there are no sharp edges on the longitudinal edge of the following packing strip 22, as can be seen particularly clearly in FIG. 9.
  • the punching line 19 of the punching tool 18 is formed from two circular lines 23 and 24 and a straight line 25 tangent to the circular lines 23 and 24.
  • the radius 26 of the circular line 23 corresponds to the radius 27 of the circular line 24.
  • the arrangement is such that the size of the radii 26 and 27 is adapted to the size of the radius 28 - rounded corners of the rear edge of the packing strips. This results in rounded corners with the same radii for each packing strip.
  • Fig. 9 also clearly shows that in this Vert way of operation and formation of the punched edge 19 of the punch Tool 18 a relatively large feed or lateral offset can occur without the known disturbing, sharp, hook-like projections. - This results from the tangent 25 connecting the two circular lines 23 and 24 to one another. This tangent 25 intersects the edge 21 of the previously punched-out packing strip, which forms the longitudinal edge of the following packing strip, in a straight region, so that an obtuse angle 29 is formed. The feed offset must of course not be so great that the circular line 23 intersects the circular line 30, since a packing strip 12 would then arise in accordance with FIG. 2.
  • the center of the circular line 24 is offset from the center 33 of the circular line 23 - as seen in the direction of advance of the packing strips 22.
