Definitions
- the invention relates to an anvil of an ultrasound sealing unit for sealing at least two material fields, which consist of plastic-coated carrier material, with a sonotrode which can be moved relative to the anvil, the sealing surface located on the front of the anvil body being profiled by means of raised and recessed areas.
- a carrier material coated with plastic As a carrier material coated with plastic, one can think of, for example, paper, cardboard or cardboard of a plastic packaging, which is sealed in various places in the manufacturing machine by sealing.
- Gable packs made of plastic-coated paper are known, the gable roof of which has two material fields sealed to one another at the top.
- a wide variety of devices can be used to seal such material fields, which can also be referred to as a double web, sealing rib, flap or upper transverse sealing seam, for example heat baking, hot air or ultrasound.
- the sealing unit according to the invention uses ultrasound, which is generated by a sonotrode and is introduced into the material fields to be sealed, which are located between the anvil and the sonotrode.
- the front surface of the sonotrode is generally flat, while the anvil opposite the sonotrode has already been profiled.
- the invention is therefore based on the object of creating an anvil of the type mentioned at the outset such that more than just two material fields or layers can be sealed to one another with the resultant ultrasound sealing unit.
- the raised areas are designed as narrow ribs, of which a lower holding rib running along the free lower edge of the sealing surface and at a distance above and parallel to the latter a central sealing rib extending over the entire width of the sealing surface are arranged.
- the direction of movement of the sealing unit, in which the anvil described here is preferably to be regarded as stationary, is perpendicular to this.
- the narrow ribs protrude from this front sealing surface as raised areas, the width of which can be, for example, 1, 5 mm or 2 mm or 3 mm, depending on the size of the material fields to be sealed.
- the sealing surface is assumed to be rectangular with a width and a height, the width is assumed to be longer than the height.
- the transverse sealing seam of the elongated material fields to be sealed with one another also extends in the direction of this width, and is moved in the direction parallel to the sealing surface and is also moved away from it again.
- This, for example, essentially rectangular sieve surface has a free lower edge, which in the preferred embodiment of the anvil is the same as the front lower edge of the anvil. At this lower edge there is the holding rib, the function of which is to hold the two material fields together while the sealing takes place over them.
- the middle rib on the other hand, namely the sealing rib, preferably extends over the entire width of the sealing surface and therefore essentially also has the width of this sealing surface explained above.
- This middle sealing rib should only be slightly interrupted, if at all.
- An anvil with this structure allows the use of ultrasound to seal material fields, and the narrow ribs (the sealing rib can also have a width comparable to the holding rib) bundle the ultrasound and thus the sealing energy in such a way that more than just two material fields or layers of, for example, plastic-coated paper, can be sealed together. Another advantage is that when the The sealing unit can be sealed even in a clean room under aseptic conditions.
- a 2-liter gable package made of plastic-coated paper is to be sealed, it has proven to be advantageous that the width of the sealing surface is approximately 120 mm, while its height is between approximately 15 and 30 mm.
- 4600 N can be applied via the retaining ribs.
- the load on the filling material and also the tensile stresses in the paper can be successfully blocked during the sealing process.
- gable packs with a holding seam can be produced, which are easier to handle by the end user, because the resulting holding seam in the product blocks when the end user squeezes a liquid-filled pack, which otherwise brings the paper to the sealing seam Tensile forces.
- the eluent pack produced with such an anvil ultimately has a better seal.
- an upper cosmetic rib is arranged at a distance above and parallel to the sealing rib.
- the above-mentioned distance between the sealing rib and the holding rib can be in the range between 3 mm and 10 mm, preferably 5 mm, if the width of the sealing surface is approximately 120 mm.
- the width of the cosmetic rib itself can be approximately 2 mm with the above-mentioned regions in the sense of wider or narrower ribs.
- the distance between the cosmetic rib and the holding rib in the case of an anvil for sealing a 2 liter gable pack is preferably 12 mm, but this distance may also be in the range between 10 mm and 15 mm. This distance also depends on the size of the pack and thus the corresponding anvil.
- the distance between the cosmetic rib and the sealing rib is then calculated as the difference between the two distances mentioned above, for a 2 liter gable pack and a width of the sealing surface of 120 mm, that is about 7 mm.
- the anvil according to the invention which is characterized in that the Kgsmetikrippe is designed as a raised plateau, the extends to the free upper edge of the material fields to be sealed.
- Both embodiments of cosmetic ribs serve to connect the material fields to be sealed together at their free upper edge so that, for example, the entire sealing rib of the gable pack is closed at the top. Not only does this look better, it also improves hygiene because there is no gap at the top of the package where the dirt or dust could fall.
- the cosmetic rib according to the second embodiment which is designed as a raised plateau, has a particularly good effect when the pack or the material fields have a raw paper edge at the top, ie a coarse, open paper edge from which dust could escape. The raised plateau then compresses the material fields and holds the fibers of the raw paper edge together by sealing.
- the raised plateau represents an optimized cosmetic rib for this purpose.
- a stop extending approximately perpendicularly from the sealing surface and extending over the entire width of the sealing surface is attached to and parallel to the upper edge of the sealing surface.
- it serves to keep the locking rib straight, i.e. setting up the top edge of the two material fields so that, for example, the sealing seam of a pack is always sealed straight.
- the stop can be used to maintain a minimum distance between the front surface of the anvil on the one hand and the sonotrode on the other hand, for example by ensuring that an arm attached to the sonotrode hits against this stop when the anvil and sonotrode move together.
- the front surface of the anvil is not necessarily identical to the sealing surface.
- the only requirement is that the sealing surface is completely on the front surface of the anvil.
- the front surface of the anvil is limited by the outer limits of the sealing surface
- another, also possible and described below, embodiment has an anvil body, the front surface of which extends beyond the abovementioned stop, for example upwards around the same Height as the sealing surface.
- a web extending over the holding rib and the sealing rib is provided as a further raised area.
- This web has an essentially flat surface parallel to the entire sealing surface and is used to compensate for differences in level of the material fields to be sealed, for example if two layers come next to three layers.
- sealing is always difficult in the areas that are step-shaped in cross-section, for example an area of two layers of material in addition to three layers. In the area of the two Among other things, the contact pressure of the sealing jaws is too low.
- the web In the direction of the width of the sealing surface, the web also has a width that is between 4 and 7 mm. The width of the web is equal to the distance between its front edge and its rear edge. Its leading edge is the one closest to the end edge of the sealing surface (at one end of its width).
- the front, approximately flat surface of the web protrudes approximately as far out of the basic or rear overall plane of the end face as the holding rib or the sealing rib. However, it is particularly preferred if the web even projects 0.2 to 1 mm forward over the foremost surface of the ribs mentioned.
- the flat front surface of the web can preferably be approximately square. This raised surface means that much more ultrasonic energy and thus sealing energy can be introduced into the material fields in front of the web than in the neighboring areas, where only a narrow sealing rib is arranged.
- thermoplastic melts on the surface of the material fields to be sealed in the area of the web, and one obtains a problem-free victory even over the level of the different layers of material arranged one above the other and next to one another, for example the level between one and two layers or two and three layers .
- the holding rib is interrupted by a recess which is located approximately half the width of the sealing surface, preferably slightly shifted towards the inlet-side end edge of the sealing surface.
- the front end edge of the sealing surface is referred to here as the inlet-side end edge because the material fields to be sealed are introduced from this side into the distance between the anvil and the sonotrode, more precisely between the sealing surface of the anvil and the front surface of the sonotrode.
- the direction of movement of the sealing rib of a gable pack is therefore parallel to the sealing surface and intermittently moves from its inlet-side end edge to the opposite, outlet-side end edge.
- the aforementioned recess is located further away from the inlet-side end edge of the sealing surface. It is particularly favorable not to arrange the recess directly halfway across the width of the sealing surface, but rather a little further to the inlet side mentioned End edge of the sealing surface.
- the word "something" means about 10 mm.
- this recess is arranged in the central region of this sealing rib, if possible.
- the cosmetic rib is interrupted by a narrow adjustment groove, the inlet-side edge of which is arranged close to the inlet-side edge of the web.
- This adjustment groove makes it easier to adjust the anvil relative to the product to be processed, i.e. relative to a material edge.
- the width of the adjustment groove is approximately 0.5-8 mm, is preferably in the range between 1 and 6 mm and has achieved good results with a width of 3 mm in a particularly preferred experiment. If it is stated that the inlet-side edge of the adjustment groove is arranged "closely" next to the inlet-side edge of the web explained above, then this is understood to mean a range of "a few millimeters" which represents the distance between the two edges.
- the area of the anvil body located behind the sealing surface is provided with a recess from the lower surface.
- a gable package with a screw cap the screw cap of which is located on one of the sloping top panels. If you now want to seal the closure seam with the anvil described according to the invention, then this must grip around the closure seam on both sides with the sonotrode, and at the same time there must be enough space for the closure cap. For this purpose, the aforementioned recess is used, which is why it is molded into the anvil body from the lower surface thereof.
- this recess means a certain weakening of the anvil body in the lower area behind the sealing surface
- the above-mentioned extension of the anvil body beyond the upper end edge of the sealing surface also results in a stiffening of the entire anvil such that the desired high compressive forces can be achieved without every warping of the tool can be transferred.
- the treatment surface can be cooled particularly well.
- the removal of higher temperatures in the area of the sealing rib and the web works well with this heat sink in the holes because the distance between the hot surfaces and the coolant holes can be kept small.
- decoupling holes are provided in the anvil body.
- ultrasonic vibrations can be decoupled from tool areas which do not need to vibrate or which are also not intended to use vibrational energy. In this way, too, the ultrasonic energy can be concentrated at those points in the material fields where heating is desired in an effective and targeted manner.
- this can be part of a sealing unit which can be used in an aseptic area for sealing sterile filled packs.
- the anvil is arranged stationary in the direction of movement relative to the sonotrode.
- the gap for introducing the material fields to be sealed to one another is generated by the movement of the sonotrode perpendicularly to and away from the sealing surface of the anvil. Due to the contour on the sealing surface of the anvil, material tolerances can be compensated for with advantage.
- Figure 1 schematically and broken the closure seam of a gable pack between
- FIG. 2 shows a first embodiment of an anvil in side view
- Figure 3 shows a second embodiment of an anvil in the view comparable to Figure
- FIG. 4 shows a perspective rear view of an anvil according to FIG. 2 or FIG. 3,
- Figure 5 is a front perspective view of an anvil according to the embodiment of
- FIG. 1 shows a broken and enlarged section according to the oval X in Figure 5.
- Two material fields 1 form a closure rib, shown in FIG. 1, of a 2 liter gable pack 2, on the inclined partial top wall 3 of which a closure cap 4, which closes a pouring opening, is attached.
- the two material fields 1 of the pack 2 to be sealed with one another are located precisely in the gap between the flat front surface ⁇ of the sonotrode 6 and the profiled sealing surface 8 of the anvil 9 Cutout 12 upwards.
- the screw cap 4 has space in the recess 12 in order to get past the tool without undesired contact.
- the anvil 9 is fastened to the frame 13, to which the sonotrode 6 is also attached via support arms 14.
- a plate-shaped decoupling slot 15 which runs parallel to the sealing surface 8 in the anvil body 10 and lateral decoupling grooves 16 which also penetrate the anvil body 10 serve to mechanically decouple the ultrasonic energy.
- a bore 17, which extends in the direction of the width B of the entire anvil and thus also its sealing surface 8, passes as a cavity through the anvil body 10, through which a flow agent, for example cooling water, can be passed. From the perspective rear view of FIG. 4, one can see screw holes 18 on the rear surface on the outside and a pin hole 19 on the inside at a distance from each other.
- the sealing surface 8 can be regarded as approximately rectangular overall with a width B (FIG. 4) and a height H (FIGS. 2 and 6). If the gable pack 2 has a volume of 2 liters, the height H is preferably 23 mm. It is useful if this height is between 15 and 30 mm.
- the total height h of the front surface 21 of the anvil is approximately twice the height H of the sealing surface.
- the width B of the sealing surface and thus also of the entire anvil is preferably 120 mm. This width extends from the front or inlet end edge 22 to the outlet end edge 23 of the sealing surface 8.
- the sealing surface 8 of the anvil 9 is profiled with raised and recessed areas. The raised areas are labeled 24-28.
- ribs 24-26 are designed as ribs 24-26, one as a stop 27 and one as a web 28.
- the lowermost rib which is designed as a lower holding rib 24, runs along the free lower edge 29 of the sealing surface 8.
- the middle sealing rib 25 runs over the entire width (B) of the sealing surface (8).
- an upper cosmetic rib 26 runs parallel to it.
- the upper edge of the sealing surface 8 is designated 31. It can be seen that the stop 27 extends at this upper edge 31 and parallel to it over the entire width B of the sealing surface 8.
- the height H of the stop 27 from the lower holding rib 24 is in the range between 15 and 30 mm and is preferably 23 mm.
- the lower holding rib 24 is interrupted by a recess 32. This is approximately half the width B of the sealing surface 8, the distance d (FIG. 6) of the recess 32 from the inlet-side end edge 22 of the sealing surface 8 in the example considered here being 50 mm, namely the center of the entire width B, minus 10 mm.
- the recess 32 is therefore somewhat closer to the inlet-side end edge 22 than to the opposite, outlet-side end edge 23.
- the cosmetic rib 26 (and also the cosmetic rib 26 'of the other in a manner not shown) Embodiment) is interrupted by a narrow adjustment groove 33.
- Their inlet-side edge 34 which in the illustration in FIGS. 5 and 6 is the left edge, closer to the inlet-side end edge 22, is arranged close to the inlet-side edge 35 of the web 28.
- the width of the web 28, measured over the entire width B of the sealing surface 8, is in the range between 4 and 7 mm, and is preferably quite exactly 7 mm.
- the center of the recess 32 from the outlet-side end edge 23 is at a distance which is between 60 and 80 mm and is preferably 70 mm.
