Definitions

  • the present invention relates to a cutting device according to claim 1 and a method for producing a cutting punch according to claim 12.
  • a cutter for punching round packaging corners is from DE 202 16 772 U1 famous.
  • Star-shaped cutting punches are used on this cutting device, which are present together with correspondingly star-shaped recesses as a punching tool.
  • the cutting punch has a two-dimensional cutting contour that corresponds to the shape to be punched out.
  • EP 3 109 017 B1 discloses a thermoforming packaging machine whose cross-cutting device is designed as a film punch in order to sever a film web in a direction transverse to the transport direction between adjacent troughs.
  • packaging in particular round packaging corners, has hitherto been punched or produced by means of crush cutting.
  • the problem is that high production costs arise in the production of stamping tools due to their high manufacturing accuracy.
  • extremely high punching forces result from the operation of punching tools, which have to be absorbed by means of a complex construction. This is also accompanied by increased energy consumption on the packaging machine.
  • the punching process can produce a significant amount of waste material, which is present, for example, in the form of a residual skeleton, which has to be wound up at the exit of a thermoforming packaging machine with a relatively large volume and then has to be disposed of at high cost.
  • increased foil consumption can occur due to the complex structure and the geometry of the punching tools.
  • the invention is based on the object of providing a cutting device and a method for producing a cutting punch, as a result of which the above disadvantages described in connection with the prior art can at least be reduced.
  • the invention relates to a cutting device that is designed to cut substantially round packaging corners from a film web, the cutting device having at least one cutting tool that includes a cutting punch that has at least one concavity on its outside that is provided for forming a cutting edge of the cutting punch is.
  • the cutting edge has a cutting contour that runs both in the transverse and in the longitudinal extension of the cutting punch.
  • the cutting contour thus runs three-dimensionally on the body of the cutting punch, i.e. not just two-dimensionally parallel to the cutting plane, as is the case with known punching punches.
  • the cutting edge according to the invention continues to cut through the film web with increasing penetration depth (i.e. advancing in the cutting or film plane) until the film cut is completely made.
  • the cutting edge can be pulled through the film web by means of comparatively low cutting forces.
  • the cutting edge when the cutting punch is in the fastened state on the cutting device, the cutting edge has a curved cutting contour when viewed both in the horizontal and in the vertical plane of projection. Consequently, the cutting edge used in the invention differs from cutting edges, such as are typically formed on cutting dies of punching tools, by a cutting contour whose profile deviates from the film shape to be cut out. This allows the cutting edge according to the invention not to pierce the film web with the entire cutting edge at once during the cutting process, but instead initially to a certain extent in a punctiform manner and, with increasing penetration depth, pulls the film web along its cutting contour and severs it.
  • the cutting edge according to the invention promotes a cutting progression along its three-dimensional cutting contour that increasingly progresses in the cutting or foil plane, which can be carried out without any problems at a high cutting speed to increase productivity and on the other hand requires lower cutting forces compared to known abrupt punching processes. Overall, the energy balance of the cutting device can also be significantly improved as a result.
  • gradually continuing along the cutting edge In the course of the cut, film sections of any shape can also be better completely cut free, because the film sections can be prevented from folding away around a residual connection.
  • Another advantage of the invention is that, in contrast to conventional punching or shearing, no recess with narrow tolerances and also no hold-down device with narrow tolerances are necessary. This reduces manufacturing costs. This also results in the possibility of a compact design for the cutting device.
  • a further consequence of this is that, by means of the cutting device according to the invention, complete film sections can be produced from the film web with a reduced use of material. As a result, both a weight-reduced residual foil lattice and better handling of the same are made possible.
  • the cutting edge preferably has a star-shaped cutting contour projected at least partially in a cutting plane.
  • This geometry favors a complete cutting free of a film section because, together with the cutting edge according to the invention, it reliably completely severs the respective remaining connections at the cutting lines that essentially converge to a point, i.e. at star points or in notches in between.
  • This is not always possible with known punches, which only have a two-dimensional cutting edge with a star-shaped cutting contour, since a residual film connection can sometimes not be completely severed because the film section deviates towards the film web instead of being completely cut out. This happens above all with known punches if the cutting speed is set too low for them or their two-dimensional cutting edge is blunted.
  • the three-dimensional and star-shaped cutting edge contour on the cutting stamp in the present variant of the invention can positively influence the ability to completely cut the film material free, even if the cutting edge sharpness is low.
  • the cutting punch has a plurality of tips, which are formed both in the transverse and in the longitudinal extension of the cutting punch.
  • the cutting stamp thus has a dome-like cutting head, the tips of which taper both in the transverse extension and in the longitudinal extension of the cutting stamp.
  • One variant provides that along the cutting contour of the cutting edge the points formed in the longitudinal extent of the cutting punch correspond to the points formed in the transverse extent of the cutting punch.
  • the longitudinal points converge with the transverse points, resulting in a molded body that is easy to produce. This would result in a star-shaped cutting contour in the horizontal projection plane.
  • the respective tips can have a comparable grinding thickness or inner curvature.
  • An inner contour produced at the tips could enclose an angle of approximately 20° to 40° towards the cutting edge, for example. Even blunt cutting edges can still lead to excellent cutting results due to the varying height of the cutting contour.
  • An expedient variant provides that along the cutting contour of the cutting edge the tips formed in the longitudinal extension of the cutting stamp are formed between the tips formed in the transverse extension of the cutting stamp. Viewed in a horizontal projection plane, the cutting punch would still have a star-shaped cutting line course, as would be the case with the longitudinal and transverse points that converge as described above. However, in contrast to the above variant, there are now external transverse peaks and internal longitudinal peaks. This can be advantageous because it allows the cutting progression to be produced from the inner longitudinal tips outwards to the outer transverse tips, so that an adjacent cutting blade bordering the cutting contour on the outside can continue to cut smoothly.
  • the cutting punch has at least one indentation which, superimposed with the first concavity, forms the cutting edge.
  • the first concavity formed on the cutting punch, together with the depression on the cutting punch can produce a three-dimensional cutting contour for the cutting edge, which provides a cutting contour progressing out of the cutting plane.
  • the indentation can be cone-shaped in the longitudinal direction of the cutting punch.
  • Such a geometry is easy to manufacture and, above all, favors the shaping of the tips described above.
  • the conical indentation together with the concavity formed on the cutting punch promotes the production of a sharp cutting edge.
  • an advantageous embodiment provides that the indentation is at least partially in the form of a truncated cone with respect to a longitudinal axis of the cutting punch. In terms of production technology, this is easy to implement because a simple CNC machine can be used for this, which can produce the cutting punch in just a few steps and without multi-axis operation.
  • the cutting punch is particularly robust and wear-resistant when it is designed in one piece.
  • the cutting stamp can be produced from a single workpiece blank, in particular by means of a machining production process. It would be conceivable, for example, to manufacture the cutting stamp using a CNC milling machine.
  • the cutting die preferably has four concavities on its outside. These can be formed on the cutting punch on the circumferential side and opposite one another, so that together they form a star shape.
  • the cutting device can be used particularly advantageously on a thermoforming packaging machine which has a forming station, a sealing station, a transverse cutting station and a longitudinal cutting station in one transport direction.
  • the cutting device can be used as a tool module at the cross-cutting station in order to cut out substantially round packaging corners from a film web, consisting of sealed packaging troughs, fed to the cross-cutting station.
  • the invention also relates to a method for producing a cutting punch which is used on a cutting device for producing round packaging corners.
  • the method according to the invention provides that at least one concavity is produced on an outer side of a workpiece blank, with a depression being produced on another side of the workpiece blank in such a way that the concavity overlaps a cutting edge of the cutting punch with a transverse and forming a cutting contour running in the longitudinal extension of the cutting punch.
  • a cutting punch produced in this way has a cutting edge with a three-dimensional cutting contour which, in order to cut a substantially round film section from a film web, cuts through the latter with increasing penetration depth. This means that a reduced use of force and a complete cut-out of the foil are possible without any problems. In addition, excellently high cutting speeds can be driven with it, which means that overall the productivity of a packaging machine on which the cutting stamp is used can be increased.
  • the method according to the invention can be carried out without any problems using a single-axis CNC machine.
  • This can be a CNC milling machine that is designed without multi-axis operation.
  • a preferred variant provides that a cylindrical milling tool is used to produce the concavity and an at least partially conical, parabolic or cylindrical milling tool to produce the depression. In this way, cost-effective production can be achieved. It would even be conceivable that the concavity and the deepening are produced using the same milling tool.
  • the cutting tool for the concavity and the cutting tool for the indentation produce the cutting edge of the cutting punch by means of an at least temporarily simultaneously controlled feed movement or are used in subsequent, separate work steps. These variants can be performed using the same CNC machine.
  • the cutting punch is hardened at least along its cutting edge by means of a thermal process. Wear resistance can thus be increased.
  • thermoforming packaging machine 1 shows an intermittently operating thermoforming packaging machine 1 in a perspective view.
  • This thermoforming packaging machine 1 has a forming station 2, a sealing station 3, a cross cutting device 4 and a longitudinal cutting device 5, which are arranged in this order in a transport direction R on a machine frame 6.
  • the thermoforming packaging machine 1 has a transport chain 11, which grips the lower film 8 and transports it further in the transport direction R per main work cycle, in particular transport chains or clamp chains 11 arranged on both sides.
  • the forming station 2 is designed as a deep-drawing station, in which depressions are formed in the lower film 8 by deep-drawing, for example by means of compressed air and/or vacuum.
  • the forming station 2 can be designed in such a way that several troughs are formed next to one another in the direction perpendicular to the transport direction R.
  • a filling section 12 is provided in the transport direction R behind the forming station 2, in which the troughs formed in the lower film 8 are filled with products.
  • the sealing station 3 has a hermetically sealable chamber 3a in which the atmosphere in the troughs is released before sealing with the upper film 10, e.g. B. evacuated and / or replaced by gas flushing, with a replacement gas or with a gas mixture.
  • the upper film 10 e.g. B. evacuated and / or replaced by gas flushing, with a replacement gas or with a gas mixture.
  • the cross-cutting device 4 is designed to cut through a film web F fed into it, consisting of the lower film 8 and the upper film 10 sealed therewith, in a direction transverse to the transport direction R between adjacent troughs.
  • the cross-cutting device 4 works in such a way that the lower film 8 is not severed over the entire width, but rather is not severed at least in an edge region. This enables controlled further transport through the transport chain 11.
  • the longitudinal cutting device 5 can be designed as a knife arrangement with which the film web F, ie the lower film 8 and the upper film 10, between adjacent troughs and are severed at the lateral edge of the lower film 8 in the transport direction R, so that there are isolated packages behind the longitudinal cutting device 5 .
  • These chain guides 13 are each protected from the outside by a side panel 14 of the thermoforming packaging machine 1 and, if necessary, attached to the side panel 14 .
  • the side panel 14 can be a sheet metal part.
  • the thermoforming packaging machine 1 also has a controller 19. It has the task of controlling and monitoring the processes taking place in the thermoforming packaging machine 1.
  • a display device 20 with operating elements 21 serves to visualize or influence the process sequences in the thermoforming packaging machine 1 for or by an operator.
  • Figures 2a to 2d show a cutting device 15 leading to the cross-cutting device 4 figure 1 heard.
  • the cutting device 15 comprises a cutting tool 16 and a hold-down device 17 positioned above it Figure 2a the cutting device 15 is shown in an open position.
  • the cutting tool 16 and/or the hold-down device 17 are mounted so that they can be adjusted in height.
  • the cutting tool 16 has a plurality of cutting punches 18 spaced apart from one another.
  • the respective cutting stamps 18 are designed to cut round packaging corners from the film web F.
  • cutting blades 22 are fixed between the respective cutting punches.
  • the cutting knives 22 can cut through the film web F in a direction transverse to the transport direction R between adjacent troughs.
  • the hold-down device 17 has a die 23 corresponding to a horizontally projected geometry of the cutting stamps 18 and the cutting knives 22 positioned between them.
  • the die 23 is equipped with star-shaped openings 24 as penetration openings for the cutting die 18, in which the show the Figures 2b to 2d ,
  • the cutting die 18 can immerse in order to produce round packaging corners in the film web F.
  • cutting punches 18 mounted on the cutting tool 16 each have a cutting edge 25, which extends both in the transverse and in the longitudinal direction of the Cutting punch 18 extending cutting contour 26 forms.
  • the cutting contour 26 is thus with respect to a cutting plane E (see Figure 3a ), in which the film web F is guided, formed three-dimensionally.
  • FIG Figures 2b to 2d How the cutting punch 18 and the cutting blade 22 positioned between them work together with the die 23 formed within the hold-down device 17 is illustrated in FIG Figures 2b to 2d shown.
  • FIG 2b shows that tips 27 formed on the respective cutting punches 18 initially dip into the die 23 formed on the hold-down device 17 when the cutting device 15 closes. This ensures that during the cutting process the film web F is not cut with the entire cutting edge 25 at once (see Figure 3a ) is pierced, but rather the points 27 are initially pricked into the film web F at certain points. The tips 27 continue to cut through the film web F with increasing penetration depth until a complete star-shaped cutout (see Fig 3g ) is made. Because the tips 27 of the respective cutting stamps 18 pierce the film web F with increasing penetration depth, ie with an increasing cross section, the respective cutting edge 25 of the cutting stamps 18 can sever the film web F with a reduced cutting force.
  • Figure 2b also shows that when the cutting device 15 is closed, the tips 27 of the cutting stamps 18 first cut the round packaging corners out of the film web F.
  • the cutting blades 22 positioned between the cutting punches 18 penetrate through the die 23 formed in the hold-down device 17, as a result of which cross-sections are produced between the round, already cut-out packaging corners.
  • the outer cutting stamps 18 shown on the cutting tool 16 have a blade 28, by means of which the film web F can be severed on its outer sides.
  • the Figures 2a to 2d show that the respective cutting dies 18 have a dome-like cutting head.
  • the cutting punch 18 with little effort pierce the tips 27 into the film web F ahead of time, resulting in a cutting path that draws into the film web F.
  • the result of this is that small tensions form within the film web F during the cutting process, which enables the film to be cut out more precisely.
  • the Figures 3a to 3g show how the cutting stamp 18 penetrates further and further with its cutting edge 25 into the film web F with increasing penetration depth.
  • the foil web F is in Figure 3a positioned within the cutting plane E. In this cutting plane E, the film web F is held in reserve for the cutting process between the cutting tool 16 and the hold-down device 17 positioned above it.
  • Figure 3a shows that the cutting stamp 18 already punctuates the film web F with its tips 27 in a punctiform manner. The tips 27 can penetrate into the film web F with comparatively little effort.
  • the Figure 3a shows that the cutting edge 25 of the cutting die 18 between the tips 27 is mostly still positioned below the film web F. As the cutting stamp 18 penetrates the film web F more and more, the cutting edge 25 cuts through the film web F more and more, resulting in a complete cutout. This is what they show Figures 3b to 3g .
