Abstract
Description
Die Erfindung betrifft ein Rotationsmesser zum maschinellen Zerteilen von Schneidgut, insbesondere von Lebensmitteln wie Käse, Wurst, Schinken und dergleichen.The invention relates to a rotary blade for the automatic cutting of cuttings, in particular of foods such as cheese, sausage, ham and the like.
Ein derartiges Rotationsmesser in Form eines scheibenförmigen Umlauf-Schneidmessers ist aus der
Derartige Schneidmesser arbeiten mit hohen Schnittfrequenzen von über 1.000 Schnitten/min. und die vom jeweiligen Produkt geschnittenen Scheiben werden bei einer industriellen Fertigung zu Stapeln herausgebildet, welche dann anschließend abgepackt werden.
Im Geschäftsbereich werden die geschnittenen Scheiben weitestgehend auf Paletten in gefächerter Form aufgelegt, um in ansprechender Form im Ladenbereich angeboten werden zu können.Such cutting blades operate at high cutting frequencies of over 1,000 cuts / min. and the slices cut by the respective product are formed into stacks in an industrial production, which are then subsequently packaged.
In the business area, the cut slices are placed on pallets in a fan-shaped form as far as possible in order to be offered in an appealing form in the shop area.
Neben rotationssymmetrischen Rundmessern haben sich in der Vergangenheit immer stärker Messer durchgesetzt, die eine sichel- oder spiralförmige Außenkontur aufweisen, wobei in einem Winkelbereich die Außenkontur eine Lücke aufweist, so dass einmal pro Umdrehung das Schneidgut durch die Lücke vorgeschoben werden kann. Durch solche Rotationsmesser, die auch als Slicermesser bezeichnet werden, lassen sich sehr viel höhere Schneidleistungen erzielen, da gegenüber den Rundmessern nicht mehr erforderlich ist, das Messer nach jedem Schnitt quer zur Rotationsachse aus dem Arbeitsbereich herauszufahren, um das zu zerschneidende Produkt für die nächste Scheibe zustellen zu können, wobei für die Schneidbewegung das Messer immer in entgegengesetzte Richtung vorgefahren werden müsste.
Mit derart ausgebildeten Schneidmessern können die Schneidleistungen von zu schneidenden Lebensmitteln wesentlich gesteigert werden. Dies bei Drehzahlen bis 1.500 Umdrehungen/min., was aber auch abhängig ist vom jeweiligen Schneidgut, insbesondere von dessen Konsistenz, die wiederum die Schnittfesdgkeit wesentlich bestimmt.
Der kontinuierliche Vorschub des Schneidgutes in Richtung des Schneidmessers bewirkt aber gleichfalls einen erhöhten Druck und somit eine erhöhte Reibung zwischen dem Schneidmesser und dem Schneidgut, was halt nicht nur zu Reibungsverlusten führt, sondern auch die Oberflächen der erhaltenen Scheiben beeinträchtigt und aufgrund der auch entstehenden höheren Reibungswärme zu optischen und geschmacklichen Beeinträchtigungen des geschnittenen Gutes führen kann.In addition to rotationally symmetrical circular blades have in the past increasingly enforced knives having a sickle or spiral outer contour, wherein in an angular range, the outer contour has a gap, so that once per revolution, the cut material can be advanced through the gap. By means of such rotary knives, which are also referred to as slicer knives, it is possible to achieve much higher cutting performance, because compared with the circular knives it is no longer necessary to move the knife out of the working area after each cut transversely to the rotation axis in order to cut the product to be cut for the next slice to be able to deliver, for the cutting movement, the knife would always have to be driven in the opposite direction.
With such trained cutting knives, the cutting performance of food to be cut can be significantly increased. This at speeds up to 1,500 revolutions / min., Which is also dependent on the particular material to be cut, in particular of its consistency, which in turn essentially determines the Schnittfesdgkeit.
However, the continuous feed of the material to be cut in the direction of the cutting blade also causes increased pressure and thus increased friction between the cutting blade and the cutting material, which not only leads to friction losses, but also affects the surfaces of the resulting discs and due to the resulting higher frictional heat can lead to visual and taste impairments of the cut material.
Die Nachteile sollen mit den Lösungen der bereits oben genannten
Zu diesem Zweck besitzen die Umlauf-Schneidmesser auf ihrer mit der Stirnfläche des Schneidgutes zusammenarbeitenden Messerseite eine verhältnismäßig kleine ringförmige Zone und einen radial weiter innen liegenden Bereich, der dem Schneidgut zugewandten Messerseite vertieft ausgebildet ist, um die Berührungsflächen zwischen dem Schneidgut und den Umlaufschneidmessern zu verringern, wodurch gleichfalls die Schwingungen in den Umlauf Schneidmessern herabgesetzt werden sollen.The disadvantages should be with the solutions of the above mentioned
For this purpose, the recirculating cutting knives have on their cooperating with the end face of the material to be cut knives a relatively small annular zone and a radially inner area, the cutting material facing knife side is formed recessed to reduce the contact surfaces between the cutting material and Umlaufschneidmessern , whereby also the vibrations in the circulation cutting knives should be reduced.
Ein Rotationsmesser der gattungsgemäßen Art ist mit der
Nachteilig bei dieser Lösung ist, dass sich beim bestimmungsgemäßen Einsatz in den Vertiefungen der Schneidkante des Schneidmessers Schneidgut ansammelt bzw. festgehalten wird, was wiederum die Schneidqualität, aber insbesondere die Qualität der geschnittenen Scheiben, negativ beeinflusst.A rotary knife of the generic type is with the
A disadvantage of this solution is that when used properly in the wells of the cutting edge of the cutting blade slicing accumulates or is held, which in turn affects the cutting quality, but especially the quality of the cut slices, negative.
Der Erfindung liegt die Aufgabe zugrunde, Rotationsmesser für Lebensmittel-Schneidemaschinen zum maschinellen Zerteilen von Schneidgut, vorzugsweise zum Schneiden von Lebensmitteln zu entwickeln, mit denen qualitätsgerechte Produktscheiben hergestellt und abgelegt werden können, dies bei einer weiteren Verbesserung der Wirtschaftlichkeit und unter Vermeidung der Nachteile der bekannten Lösungen des Standes der Technik.The invention has for its object to develop rotary blade for food slicing machines for machine cutting of cutting material, preferably for cutting food, with which quality product slices can be produced and stored, this with a further improvement in cost-effectiveness and avoiding the disadvantages of the known Solutions of the prior art.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst, besondere Ausgestaltungen und vorteilhafte Lösungen sind in den Unteransprüchen angegeben.This object is achieved with the features of claim 1, particular embodiments and advantageous solutions are given in the dependent claims.
Die Merkmale des Oberbegriffs des Anspruchs 1 sind dabei aus der
Nach der Erfindung hergestellte Rotationsmesser in Form von Sichelinessern und Kreisessem sind durch die Ausbildung und Gestaltung ihrer Schneidenbereiche charakterisiert, welche herausgebildet werden durch die Schneide des jeweiligen Rotationsmessers und der sich der Schneide anschließenden Schneidenfläche, welche mit vorbestimmbaren Winkeln, den Schneidenwinkeln, ausgebildet sind.
Dies in der Art und Weise, dass die umfänglich umlaufende Schneidenfläche eines Rotationsmessers mit schneidenwinkelveränderlicher Größe ausgeführt ist, somit die jeweilige Schneidenfläche, wiederum bezogen auf deren umfänglichen Umlauf, eine wellenförmig verlaufende Oberflächenstruktur besitzt.
Dabei gehört es gleichfalls zur Erfindung, dass die Schneidenwinkel von nach der Erfindung hergestellten Rotationsmessern in stetiger oder unstetiger Folge mit ungleichgroßen Winkelmaßen ausgebildet sind, wobei die einzelnen Schneidenwinkel an jeder Stelle der jeweiligen Schneidenfläche vorgesehen werden können, was insbesondere abhängig ist von den zu schneidenden Produkten.Rotary blades made in accordance with the invention in the form of sickle liqueurs and circular knives are characterized by the design and configuration of their cutting edges, which are formed by the cutting edge of the respective rotary blade and the blade surface adjoining the blade, which are formed with predeterminable angles, the cutting angles.
This in such a way that the circumferentially circumferential cutting surface of a rotary knife is designed with cutting angle variable size, thus the respective cutting surface, again with respect to the circumferential circulation, has a wavy running surface structure.
It is also part of the invention that the cutting angle of rotary knives according to the invention are formed in a continuous or discontinuous sequence with unequal angular dimensions, the individual cutting angle can be provided at any point of the respective cutting surface, which is particularly dependent on the products to be cut ,
Durch die Ausbildung der Schneidenbereiche, speziell der Schneidenflächen mit unterschiedlich großen Schneidenwinkeln und deren umfänglichen Ausbildungen auf den Schneidenflächen der Rotationsmesser, werden qualitätsgerechte Schneidvorgänge gewährleistet. Dies betrifft sowohl die Schneidvorgänge beim unmittelbaren Anschnitt des zu schneidenden Produktes, aber auch in der weiteren Folge des gesamten Schneidvorganges und des sich daran anschließenden Ablegens der geschnittenen Produktscheiben. Durch die Wahl der unterschiedlichen Schneidenwinkel und deren Ausbildungen auf der Schneidenfläche eines Rotationsmessers sind die Möglichkeiten geschaffen worden, den Schneidvorgang unmittelbar dem jeweils zu schneidenden Produkt anzupassen, dies sowohl beim Anschnittvorgang, dem weiteren Durchschneiden und dem Ablegen, da die einzelnen Lebensmittelprodukte unterschiedliche Konsistenzen und Festigkeiten besitzen. Unter Berücksichtigung dieser Eigenschaften erfolgt die Ausbildung und Anordnung der Schneidenwinkel auf der jeweiligen Schneidenfläche, somit werden Schneidenbereiche von Rotationsmessern geschaffen, die den gegebenen praktischen Bedingungen gerecht werden, was sich in verbesserten Schneidvorgängen und verbesserten Produktqualitäten von geschnittenen Lebensmitteln ausdrückt.Due to the design of the cutting areas, especially the cutting surfaces with different sized cutting angles and their circumferential formations on the cutting surfaces of the rotary blades, quality cutting processes are guaranteed. This applies both to the cutting operations in the immediate cut of the product to be cut, but also in the further consequence of the entire cutting process and the subsequent deposition of the sliced product slices. By choosing the different cutting angle and their training on the cutting surface of a rotary blade, the possibilities have been created to adjust the cutting process directly to the respective product to be cut, both the gate, the further cutting and depositing, since the individual food products different consistencies and strengths have. Taking into account these properties, the formation and arrangement of the Cutting angle on the respective cutting surface, thus cutting areas of rotary knives are created that meet the given practical conditions, which is reflected in improved cutting operations and improved product qualities of cut foods.
Von besonderem Vorteil ist, dass die Schneidenbereiche von Rotationsmessern in den bereits genannten Formen, ob als Sichelmesser oder Kreismesser ausgebildet, gemäß der Erfindung gestaltbar sind.
Dies betrifft auch typische Aufschnitt-Schneidmesser, welche in der Praxis als Slicermesser bekannt sind.
Hier handelt es sich um Sichel- oder auch Kreismesser. Die Sichelmesser sind dabei mit einem Ausschnitt ausgebildet, so dass bei jedem Umlauf des Slicermessers durch diese Lücke der Vorschub des Schneidgutes erfolgt. Kreismesser, welche als Aufschnitt-Schneidmesser zum Einsatz kommen, sind in ihrer kreisrunden Grundstruktur unverändert, laufen um ihre Achse um und werden, um den Vorschub des Schneidgutes zu gewährleisten, in wechselnder Folge vom Schneidgut weg oder zum Schneidgut geführt oder alternativ erfolgt die Zuführung bzw. Rückführung des Schneidgutes zum Kreismesser.
Die Ausbildung und Gestaltung der Schneidenbereiche dieser Slicermesser erfolgt nach den Merkmalen der vorliegenden Erfindung.It is particularly advantageous that the cutting areas of rotary blades in the forms already mentioned, whether designed as sickle blades or circular blades, can be shaped according to the invention.
This also applies to typical sliced cutting knives, which are known in practice as slicer knives.
These are sickle or circular knives. The sickle blades are formed with a cutout, so that with each revolution of the slicer blade through this gap, the feed of the material to be cut takes place. Circular knives, which are used as a slicing knife, are unchanged in their circular basic structure, run around their axis and, in order to ensure the feed of the material to be cut, are guided in alternating sequence away from the material to be cut or to the material to be cut or, alternatively, the supply or Return of the material to be cut to the circular blade.
The design and design of the cutting areas of these slicer knives is carried out according to the features of the present invention.
Es liegt im Rahmen der Erfindung, dass die jeweilige Schneidenfläche eines Rotationsmessers mit Schneidenwinkeln ausgebildet ist, welche in wechselnder Folge unterschiedliche Winkelmaße besitzen.It is within the scope of the invention that the respective cutting surface of a rotary blade is formed with cutting angles, which have different angular dimensions in alternating sequence.
Durch die unterschiedliche Ausbildung der Schneidenwinkel und deren Ausbildung und Anordnung auf den Schneidenflächen von Rotationsmessern, werden der Prozess des Anschneidens des zu schneidenden Gutes und der sich nachvollziehende weitere Schneidvorgang positiv beeinflusst. Ferner wird auch der Ablageimpuls der geschnittenen Produktscheiben positiv beeinflusst, da ein stumpfer Schneidenwinkel sich positiv auf das Ablegen der geschnittenen Produktscheiben auswirkt, demgegenüber ein relativ stumpfer Schneidenwinkel für den Anschneidvorgang negativ wirkt, so dass es vorteilhaft ist, im Anschnittbereich einen Schneidenwinkel mit einem geringeren Winkelmaß gegenüber dem nachgeordneten Schneidenwinkel für das Ablegen auszufuhren.
Die Kombination und Wählbarkeit der größenmäßigen Ausbildung der Schneidenwinkel und deren Anordnung auf der jeweiligen Schneidenfläche beeinflussen somit positiv die Schneidvorgänge, dies in Abhängigkeit der vorherrschenden Bedingungen beim Schneiden von Lebensmittelprodukten unterschiedlicher Festigkeiten und Konsistenzen.
Dabei kommt ferner vorteilhaft zum Tragen, dass die Modifikation des oder der Schneidenwinkel senkrecht zur Fortbewegungsrichtung des Schneidgutes sowohl die Schneidkräfte beeinflusst werden als auch der Ablagevorgang von geschnittenen Produktscheiben.Due to the different design of the cutting angle and their formation and arrangement on the cutting surfaces of rotary blades, the process of cutting the material to be cut and the traceable further cutting process are positively influenced. Furthermore, the deposit pulse of the sliced product slices positively, since a blunt cutting angle has a positive effect on the laying of the sliced product slices, while a relatively blunt cutting angle for the cutting process has a negative effect, so that it is advantageous to perform a cutting angle in the gate area with a smaller angle with respect to the downstream cutting angle for depositing ,
The combination and selectability of the size design of the cutting edges and their arrangement on the respective cutting surface thus positively influence the cutting operations, depending on the prevailing conditions when cutting food products of different strengths and consistencies.
It is also advantageous to bear in mind that the modification of the edge angle or angles perpendicular to the direction of movement of the material to be cut both the cutting forces are affected and the storage process of sliced product slices.

Der Schneidenfläche 3 schließt sich in radialer Richtung ein schräges Flächenteil 4 an, welches übergeht in ein parallel verlaufendes Flächenteil 6, welches, bezogen auf die Mittelachse des Sichelmessers 1, senkrecht verläuft.
Im Flächenteil 6 des Sichelmessers 1 ist im Zentrum vom Sichelmesser 1 eine Aufnahmeöffnung 9 vorgesehen, über welche das Sichelmesser 1 zur Aufnahmeeinheit einer Lebensmittelschneidemaschine Aufnahme findet. Über gleichfalls im Flächenteil 6 vorgesehene Durchgangsbohrungen 11 erfolgt die Befestigung des Sichelmessers 1 zur Lebensmittelschneidemaschine. Vorgesehene Bohrungen 10 im Flächenteil 6 des Sichelmessers 1 dienen der Aufnahme von Auswuchtkörpern, um den Rundlauf des Sichelmessers 1 zu gewährleisten.
Um einen Lagebezug zwischen dem Schneidenwinkel 7 des Sichelmessers 1 zu dessen Drehbewegung fixieren zu können und somit in der Folge die Anordnung weiterer Schneidenwinkel, ist auf dem Flächenteil 6 vom Sichelmesser 1 ein sogenannter Kodierpunkt 8 vorgesehen.Starting in the
