Abstract

A strip-shaped or reciprocating knife has at least ore elongated cutting blade (1) provided with a plurality of cutting teeth (2) and intermediate cutting gaps (5), the cutting teeth (2) being provided with additional, finer teeth (8). In order to achieve from beginning to end a smooth and clean cut of the goods to be cut, the additional teeth (8) are produced by providing opposite tooth spaces (9) on both sides of the knife, arranged so close to one another that sharp teeth (12) are formed between the spaces. The additional teeth provided on both sides of the knife form a sharp cutting edge which is symmetrically arranged on both sides of the knife and extends over the cutting teeth (2).

Description

Die Erfindung betrifft ein Band- oder Gattermesser mit mindestens einem langgestreckten Schneidblatt, das eine Vielzahl von Schneidzähnen und dazwischenliegenden Schneidlücken aufweist, wobei die Schneidzähne mit einer zusätzlichen feineren Verzahnung versehen sind.The invention relates to a band or gate knife with at least an elongated cutting blade that has a variety of cutting teeth and intermediate cutting gaps, being the cutting teeth with an additional finer Teeth are provided.

Ein derartiges Bandmesser ist aus der DE 41 38 025 A1 bekannt. Die Schneide des in dieser Druckschrift offenbarten Bandmessers ist durch schräg verlaufende Zuschliffsflächen auf einer oder auf beiden Seiten des Messers gebildet. Bei einseitiger Zuschliffsfläche sind die Zahnlücken der zusätzlichen Verzahnung ebenfalls einseitig eingebracht. Bei beidseitigen Zuschliffsflächen sind die Zahnlücken der zusätzlichen Verzahnung in abwechselnden Abschnitten auf beiden Seiten des Messers in die Zuschliffsflächen eingeschliffen.Such a band knife is known from DE 41 38 025 A1. The cutting edge of the band knife disclosed in this publication is due to inclined grinding surfaces on one or formed on both sides of the knife. With one-sided The grinding surface is the tooth gap of the additional toothing also introduced on one side. With grinding surfaces on both sides are the tooth gaps of the additional toothing in alternating sections on both sides of the knife ground into the ground surfaces.

Weist bei dem bekannten Messer nur eine Seite der Schneide eine schräg verlaufende Zuschliffsfläche mit darin eingeschliffenen Zahnlücken auf, so sind beide Seiten der Schneide durchgehend asymmetrisch zueinander ausgebildet. Als Nachteil dieser asymmetrischen Anordnung hat sich herausgestellt, daß das Messer beim Schneiden des Gutes aus seiner Geradeausrichtung zu der von der Zuschliffsfläche abgewandten Seite quer zur Laufrichtung abgelenkt wird. Ein gerader, glatter Schnitt kommt daher nicht zustande.Has only one side of the cutting edge in the known knife a sloping ground surface with ground in it Tooth gaps are on both sides of the cutting edge consistently asymmetrical to each other. As a disadvantage this asymmetrical arrangement has been found that the knife when cutting the material from its straight line across to the side facing away from the ground surface is deflected to the direction of travel. A straight, smooth cut therefore does not come about.

Da bei beidseitigen Zuschliffsflächen der Schneide die Zahnlücken der zusätzlichen Verzahnung in aufeinanderfolgenden Abschnitten abwechselnd auf beiden Seiten eingeschliffen sind, ergeben sich in Querrichtung des Bandmessers versetzt zueinander angeordnete Schneidbereiche in den Zahnlücken der zusätzlichen Verzahnung. Die mit einer bestimmten Breite versetzt zueinander angeordneten Schneidbereiche führen zu einem erhöhten Reibwiderstand beim Schneiden des Gutes. Der Reibwiderstand hat seinerseits eine Erwärmung des Messers sowie des geschnittenen Gutes zur Folge. Darüber hinaus fällt durch den sich über eine bestimmte Breite erstreckenden Versatz der Schneidbereiche ein Verlust von Schneidgut an. Dieser Verlust oder andere Rückstände des Schneidgutes setzen sich dann leicht in den Schneidlücken und Zahnlücken der zusätzlichen Verzahnung fest. Bei zusätzlicher Erwärmung verkleben die Schneidverluste und Rückstände leicht das Messer, was sich insbesondere bei frischen Backwaren bemerkbar macht. Daher läßt bei seitlichem Versatz der Schneidbereiche ein glatter, sauberer Anschnitt und Durchschnitt des Gutes zu wünschen übrig.Because there are tooth gaps on both sides of the cutting edge the additional interlocking in successive Sections are alternately ground on both sides, arise in the transverse direction of the band knife offset to each other arranged cutting areas in the tooth gaps of the additional Gearing. The offset with a certain width mutually arranged cutting areas lead to a increased frictional resistance when cutting the material. The frictional resistance in turn has a heating of the knife as well of the cut good. It also fails the offset of the over a certain width Cutting areas a loss of material to be cut. That loss or other residues of the material to be cut will then settle easily in the cutting gaps and tooth gaps of the additional Gearing firmly. With additional heating, they stick together Cutting losses and residues easily the knife what is especially noticeable with fresh baked goods. Therefore leaves a smooth, clean cut and average of the good to be desired left.

Herstellungstechnisch ist das aus der DE 41 38 025 A1 bekannte Bandmesser zudem relativ aufwendig. Zur Herstellung der Schneide werden zuerst die schräg verlaufenden Zuschliffsflächen auf beiden Seiten des Bandmessers angebracht. Dann erfolgt das Einschleifen der wellenförmigen Schneidzähne und Schneidlücken sowie der zusätzlichen Verzahnung abwechselnd auf beiden Seiten in bestimmten Abschnitten.Technically, this is known from DE 41 38 025 A1 Band knives also relatively expensive. To make the First cut the oblique ground surfaces attached to both sides of the band knife. Then grinding of the wave-shaped cutting teeth and Cutting gaps and the additional toothing alternately on both sides in certain sections.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Band- oder Gattermesser zu schaffen, das einen optimal glatten sauberen Schnitt und Durchschnitt des Schneidgutes gewährleistet und einfach herzustellen ist.The present invention is based on the object To create band or gate knives that are optimally smooth ensures clean cut and average of the material to be cut and is easy to manufacture.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einem Band- oder Gattermesser der eingangs genannten Art die zusätzliche Verzahnung durch beidseitiges, gegenüberliegendes Einbringen von Zahnlücken hergestellt ist, die so eng benachbart zueinander angeordnet sind, daß sich zwischen ihnen scharfe Zähne herausbilden und die beidseitig eingebrachte zusätzliche Verzahnung eine sich über die Schneidzähne erstreckende und beidseitig symmetrische scharfe Schneide bildet. The object is achieved in that at one Band or gate knife of the type mentioned the additional Interlocking through bilateral, opposite insertion is made up of tooth gaps that are so closely adjacent are arranged to each other, that between them sharp Form teeth and the additional one introduced on both sides Toothing extending over the cutting teeth and symmetrical sharp edge on both sides.

Aufgrund der erfindungsgemäßen Konstruktion des Band- oder Gattermessers wird ein im Querschnitt auf beiden Seiten symmetrisches Schneidblatt mit einem in der Symmetrieebene sich über die Schneidzähne erstreckenden Schneidbereich erreicht. Dadurch wird der Reibwiderstand auf ein Minimum reduziert. Es ergibt sich ein glatter sauberer Schnitt des Schneidgutes mit einem einheitlichen Schnittbild. Der Verlust von Schneidgut wird ebenfalls erheblich reduziert. Da die beidseitig eingebrachte zusätzliche Verzahnung die Schneide des Messers bildet, entfällt ein gesondertes, vorangehendes Zuschleifen des Schneidblattes in Form von Zuschliffsflächen auf beiden Seiten des Messers. Der Herstellungsaufwand verringert sich daher erheblich.Due to the construction of the tape or Gate knife becomes a symmetrical cross section on both sides Cutting blade with one in the plane of symmetry itself reached over the cutting teeth extending cutting area. This reduces the frictional resistance to a minimum. It the result is a smooth, clean cut of the material to be cut a uniform sectional view. The loss of clippings is also significantly reduced. Because the inserted on both sides additional teeth form the cutting edge of the knife, there is no separate, previous grinding of the Cutting blade in the form of ground surfaces on both sides of the knife. The manufacturing effort is therefore reduced considerably.

Vorzugsweise erstreckt sich die Feinverzahnung über das gesamte Schneidblatt, so daß auch die Schneidlücken mit der zusätzlichen Verzahnung versehen sind.The fine toothing preferably extends over the entire Cutting blade, so that the cutting gaps with the additional teeth are provided.

In einer besonders vorteilhaften Ausführung ist die Feinverzahnung durch beidseitiges Einbringen von Zahnlücken hergestellt, so daß sich zwischen den eingebrachten Zahnlücken Zähne herausbilden und die Zähne und Zahnlücken jeweils beidseitig gegenüberliegen. Das Einbringen der Zahnlücken kann z. B. durch Schleifen, Fräsen oder Stanzen erfolgen.The fine toothing is in a particularly advantageous embodiment produced by inserting tooth gaps on both sides, so that between the introduced tooth gaps Form teeth and the teeth and tooth gaps on both sides opposite. The insertion of the tooth gaps can e.g. B. done by grinding, milling or punching.

Aufgrund der erfindungsgemäßen zusätzlichen Verzahnung hat sich überraschenderweise herausgestellt, daß selbst schnelllaufende Bandmesser sich gegenüber herkömmlichen Bandmessern beim Schneiden des Produktes sich nicht mehr so stark erwärmen. Dies trägt einerseits dazu bei, daß das Schneidgut bedeutend weniger zum Verkleben in den Schneidlücken und an den Schneidzähnen neigt und somit sich ein gleichmäßiger Schnitt ergibt. Andererseits kann das Schneidgut bei einer höheren Temperatur gefahren und somit die Auskühlzeit zum Beispiel des zu schneidenden Backgutes verkürzt werden, was eine höhere Produktivität des gesamten Herstellungs- und Arbeitsverfahrens ermöglicht. Because of the additional toothing according to the invention surprisingly, it turned out that even high-speed Band knife compared to conventional band knives no longer heat up so much when cutting the product. On the one hand, this contributes to the fact that the material to be cut is significant less for gluing in the cutting gaps and on the Cutting teeth tends and therefore a uniform cut results. On the other hand, the material to be cut can be used at a higher level Temperature and thus the cooling time, for example the baked goods to be cut, which is a higher Productivity of the entire manufacturing and working process enables.

Weiterhin hat sich überraschenderweise herausgestellt, daß durch die zusätzliche Verzahnung die Geräuschentwicklung insbesondere bei schnellaufenden Bandmessern gegenüber herkömmlichen Bandmessern erheblich reduziert wird.Furthermore, it has surprisingly been found that due to the additional toothing the noise development in particular with high-speed band knives compared to conventional ones Band knives is significantly reduced.

In einer bevorzugten Ausführung sind die beidseitig angeschärften Bereiche der Schneidzähne und Schneidlücken durch die beidseitig eingebrachte zusätzliche Verzahnung gebildet.In a preferred embodiment, they are sharpened on both sides Areas of the cutting teeth and cutting gaps the additional toothing introduced on both sides is formed.

Die Schneidzähne können beidseitig mit einer Vorfase versehen sein.The cutting teeth can be pre-chamfered on both sides his.

Die Ausbildung der feinverzahnten Schneidzähne kann den Anforderungen an das zu schneidende Produkt angepaßt werden. Insbesondere können die Schneidzähne spitz ausgebildet sein, so daß ihre beidseitigen Flanken konkav gebogen sind und in die ebenfalls konkav gebogenen Schneidlücken übergehen. Andererseits können die Schneidzähne auch konvex gebogen sein, so daß ihre beidseitigen Flanken mit einem konvexen Bogen in die konkav gebogenen Schneidlücken übergehen.The formation of the fine-toothed cutting teeth can meet the requirements be adapted to the product to be cut. In particular, the cutting teeth can be pointed, so that their flanks on both sides are concave and in the concavely curved cutting gaps also pass. On the other hand the cutting teeth can also be convex, so that their flanks on both sides with a convex arc in the pass over concave curved cutting gaps.

Wie aus der Zeichnung hervorgeht, bestehen die Band- oder Gattermesser aus mindestens einem langgestreckten Schneidblatt 1, das eine Vielzahl von Schneidzähnen 2, 3 bzw. 4 und dazwischenliegenden Schneidlücken 5, 6 bzw. 7 aufweist. Die Schneidzähne 2, 3 bzw. 4 und Schneidlücken 5, 6 bzw. 7 sind beidseitig mit gleichem Fasenwinkel angeschärft.As can be seen from the drawing, the band or Gate knife made of at least one elongated cutting blade 1, which has a plurality of cutting teeth 2, 3 or 4 and in between Gaps 5, 6 and 7 respectively. The Cutting teeth 2, 3 and 4 and cutting gaps 5, 6 and 7 are sharpened on both sides with the same bevel angle.

Die angeschärften Bereiche der Schneidzähne 2, 3 bzw. 4 und Schneidlücken 5, 6 bzw. 7 sind mit einer zusätzlichen, feineren Verzahnung 8 versehen. Die Verzahnung 8 ist durch beidseitiges Einschleifen, Fräsen oder Stanzen von Zahnlücken 9, 10 bzw. 11 hergestellt, so daß sich zwischen den Zahnlücken 9, 10 bzw. 11 Zähne 12, 13 bzw. 14 herausbilden und die Zähne 12, 13 bzw. 14 und Zahnlücken 9, 10 bzw. 11 jeweils beidseitig gegenüberliegen. Die beidseitig angeordnete zusätzliche Verzahnung 8 bildet die angeschärften Bereiche der Schneidzähne 2, 3 bzw. 4 und Schneidlücken 5, 6 bzw. 7. Ein gesondertes, vorangehendes Anschärfen der Schneidzähne 2, 3 bzw. 4 und Schneidlücken 5, 6 bzw. 7 mit einem bestimmten Fasenwinkel kann daher entfallen.The sharpened areas of the cutting teeth 2, 3 or 4 and Cutting gaps 5, 6 and 7 are with an additional, finer Provide teeth 8. The toothing 8 is by bilateral Grinding, milling or punching tooth gaps 9, 10 or 11 produced so that between the tooth gaps 9, 10th or 11 teeth 12, 13 or 14 and the teeth 12, 13 or 14 and tooth gaps 9, 10 or 11 are opposite each other on both sides. The additional toothing arranged on both sides 8 forms the sharpened areas of the cutting teeth 2, 3 or 4 and cutting gaps 5, 6 and 7. A separate, preceding one Sharpening of cutting teeth 2, 3 or 4 and cutting gaps 5, 6 or 7 with a certain bevel angle can therefore be omitted.
