Definitions
- the invention also relates to a rotary drivable cutting blade for machines for slicing food products, in particular for high-speed slicer, which is attached to a drive shaft by means of an assembly area surrounding an axis of rotation, and outside the assembly area and within a cutting area a primarily flat distance range having.
- a cutting blade of this type is known from DE 10 2009 006 912.
- the circular cutting blade has elevations in the cutting area, which are intended to reduce the friction between the blade surface and the food slices.
- the elevations are formed as a dome-shaped or spherical segment-shaped ribs.
- the separated food disc is to touch only the crests of the ribs during the cutting process, whereby the friction between the food product and the knife is reduced.
- the elevations are for this purpose immediately adjacent to the cutting edge.
- Knives of the type mentioned rotate at a rotational speed of at least 1500 revolutions per minute and must be as stiff as possible and optimally balanced to produce an immaculate material to be cut.
- the elevations are held with plug-like fastening sections, which are anchored in the knife. As a result, there is no significant stiffening of the knife, although the elevations increase it at least in the cutting area.
- the invention is based on the object in cutting blades of the type mentioned in minimizing the weight to increase the rigidity and to achieve a good quality cutting.
- embossed in the distance range mutually recessed and raised formations are available.
- embossing of formations within the distance range a microstructural consolidation takes place which, at the same time as the shape of the shaping, results in a higher rigidity of the cutting blade.
- the formations are located in the distance range of the cutting blade, ie outside the cutting area, whereby they can be shaped so that they neither touch the food product nor the slices to be separated therefrom. ever According to shape, the formations can also serve to generate primarily local air angles in the rotating blade, thereby reducing the distraction of cut food slices. Since such cutting knives are to be statically and dynamically balanced, the formations can also be used to optimize the balancing. Due to the mutual forming a dynamic imbalance is almost avoided. At the same time a lesser plan strike is achieved.
- the structural strengthening effected by the embossing can still contribute to a considerable weight reduction of the cutting blade, since the material thickness can be reduced by an increased rigidity of the blade.
- the embossed formations have at most the same material thickness as the surrounding areas of the distance range. By embossing the formations can also be achieved a reduction in material thickness. This applies in particular to deep drawing of the formations.
- the shape of the formations can be chosen manifold. If you want to achieve the known from golf balls dimple effect in the cutting blade, the formations can be designed circular. If the formations should have an elongated shape, hollows are recommended. These may have a level reason to avoid sharp kinks, edges or breaks.
- the formations are radially extending, elongated troughs, grooves or ribs.
- the radial alignment increases the stiffness against the bend.
- the formations can be arranged over the circumference alternately to the inner and the outer side of the knife, so that - seen in the circumferential direction - results in a mountain-valley pattern.
- the flat distance range is thereby somewhat resolved by the alternating formations merge into each other and adjusts a wave pattern in the circumferential direction.
- This wave pattern requires a very high rigidity of the blade against deflection.
- the invention can be applied not only to a circular blade but also to a sickle blade. If necessary, the formations can be used specifically for the dynamic balancing.
- a cutting machine knife in particular a cutter knife is known in which radially in succession recesses and / or elevations are provided. You are not in the cutting area, but immediately behind it to get in contact with the shredded material.
- the depressions and elevations are therefore intended to improve the reduction performance, to increase the protein digestion and to achieve a more intensive emulsification of the material to be cut.
- a better sausage swirling should be achieved by the depressions and / or elevations.
- the depressions and / or elevations analogous to DE 10 2009 006 912 serve to contact the material to be cut, which is not the purpose of the invention.
- FIG. 1 the top view of a sickle knife according to the invention
- FIG. 2 a sector section of the sickle blades of FIG. 1 in perspective view
- FIG. 3 shows a plan view of a further embodiment of a sickle blade according to the invention
- FIG. 4 shows a sector section of the cutting blades of FIG. 3,
- Figure 5 a plan view of a third embodiment of a cutting blade according to the invention.
- FIG. 6 shows a sector cutout of the cutting blade of FIG. 5.
- the cutting blade 10 shown in FIG. 1 is intended for machines not shown for slicing food products, in particular for high-speed slicers. It has an assembly area 11 which surrounds an axis of rotation 12, the latter being guided centrally through a circular bore 13.
- the cutting blade 10 is fixed on one side by means of the mounting portion 1 to a drive shaft, not shown.
- a drive shaft not shown.
- it is designed as a sickle knife, it corresponds with its features those of DE 10 2007 040 350.
- Such sickle blades have a cutting edge 14, which deviates from a circular shape by circulating outwardly in a spiral around the axis of rotation 12.
- the cutting edge begins at an incision and ends at a radial end edge 16.
- the cutting edge 1 is flanked by a cutting area 17 between the mounting portion 11 and the cutting portion 17 extends a distance range 18.
- embossed protrusions 19 which are raised above the level of the distance range.
- the embossing is done primarily by deep drawing, whereby the formations are solidified in their structure, and have a slightly lower material thickness d as the surrounding, non-embossed distance range 18th
- the formations are circular, the diameter of the circles being smaller in the direction of the axis of rotation 12.
- the formations are alternately raised to the inner and the outer side of the knife, so that - figuratively speaking - mountains and valleys alternate. In the present case, the formations have a flat reason, but it is conceivable, the reason even uneven, for example, bulbous shape.
- the formations can be arranged one behind the other in the radial direction, with "mountains” and “valleys” also alternating in the radial direction. The same also applies in the circumferential direction, as can be seen for example from the sector detail of Figure 2.
- embossing the troughs not only a high rigidity of the cutting blade is achieved in total, but also a structural hardening within the deformations. This also leads to a smaller flick of the knife.
- embossing the troughs in an alternating direction inwards and outwards the dynamic balancing of the knife is ensured.
- the Aüsformungen are provided with throats 21, each producing the connection to the plane of the distance range 18, and the base 20. These throats can become smaller and flatter towards the axis of rotation to keep the stiffness from the knife center to the cutting edge.
- the circular formations can achieve a flow effect in the same way as the depressions (dimples) in the golf ball.
- the secondary angle reduces the air friction. Air swirls cause a reduced deflection of interleavers used during portioning. The same applies to the filing of the discs.
- the cutting blade becomes significantly stiffer, which can reduce the material thickness and weight of the knife. The same applies to the counterweight.
- FIG. 3 likewise shows the plan view of a sickle knife.
- the formations 19 are not circular, but elongated wells extending in the radial direction.
- the troughs have a flat bottom, but they can also be bulbous, wherein the bulge can extend to both the inside and the outside of the knife.
- the formations are raised alternately to the inside and outside of the knife. They are arranged one behind the other in the radial direction, alternated not only in the radial direction, but also in the circumferential direction in each case inwardly and outwardly raised formations.
- the embossing pattern is repeated from the closing edge 16 in the circumferential direction in the direction of the incision 15, wherein the dimensions become increasingly smaller analogous to the hole pattern of Figure 1.
- the formations are therefore greatest near the end edge 16 and smallest at the other end.
- the formations are each wider at their radially outer end than at their radially inner end.
- adjacent formations have a straight corner edge 22 in each case in the assembly area 1 or in the cutting area 17.
- the formations 19 are also deeper in the radial direction, wherein the depth is limited by the fact that during the cutting process, the molding should not touch the material to be cut.
- the cutting area 17 encloses an angle ⁇ with the plane of the distance range 18.
- Figures 5 and 6 show a further embodiment of the invention.
- the formations 19 extend in this case continuously from the cutting area 17 to the mounting area 1 1. They are shaped as radial, elongated, continuous troughs. They are raised relative to the plane of the distance range and change in the circumferential direction from the Messerinnen- and the knife outside raised formations, so again in the circumferential direction results in a mountain-valley shape. Especially in this embodiment, it is conceivable to make the mountain and valley formations into a wave formation, whereupon the planar webs 23 of the distance range which are still visible in FIG. 5 disappear.
- the formations 19 each have straight end edges 22 at their radially inner and at the radially outer end.
