Description

Die Erfindung betrifft eine Vorrichtung zum Schneiden von Obst, Gemüse oder dergleichen in Scheiben mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a device for cutting fruit, vegetables or the like into slices with the features of the preamble of claim 1.

Bei einer solchen aus der GB-A-1 586 848 bekannten Vorrichtung verlaufen die Spitzen der Messerklingen jeweils winklig aus und sind winklig aneinander angesetzt. Auch die Profile der Messerklingen stoßen dabei stumpf aufeinander. Dies beeinträchtigt die Stabilität der Messerklingen.In such a device known from GB-A-1 586 848, the tips of the knife blades each run out at an angle and are attached to one another at an angle. The profiles of the knife blades also butt against each other. This affects the stability of the knife blades.

Eine ähnlich ausgebildete Vorrichtung zeigt die EP 0 306 017 A2, die in den Figuren 1 und 2 dargestellt ist, wobei Fig. 2 in vergrößerter Darstellung die Anordnung der Messerklingen der in Fig. 1 gezeigten Vorrichtung wiedergibt.A similarly designed device is shown in EP 0 306 017 A2, which is shown in FIGS. 1 and 2, FIG. 2 showing the arrangement of the knife blades of the device shown in FIG. 1 in an enlarged view.

Wie in Fig. 1 dargestellt, umfaßt die bekannte Vorrichtung 1 zwei Rahmenleisten 2, die in ihrem hinteren Teil von einer Messerhalteplatte 4 und in ihrem vorderen Teil von zwei an der Unterseite der Vorrichtung 1 angeordneten und in der Zeichnung nicht dargestellten Querstegen zusammengehalten sind. Im vorderen Teil der Vorrichtung 1 ist eine parallel zur Messerhalteplatte 4 einschiebbare Schieberplatte 8 angeordnet, die in einer seitlichen Nut in den Rahmenleisten 2 geführt wird und in eingerastetem Zustand so angeordnet ist, daß zwischen dem hinteren Abschnitt der Schieberplatte 8 und einem Schneidmesser 6, das am vorderen Rand der Messerhalteplatte 4 befestigt ist, ein schmaler Spalt verbleibt. Die Schieberplatte 8, auf der das Schneidgut geführt wird, weist zusätzlich für diesen Zweck vorgesehene Längsrillen 9 auf.As shown in Fig. 1, the known device 1 comprises two frame strips 2, which are held together in their rear part by a knife holding plate 4 and in their front part by two transverse webs arranged on the underside of the device 1 and not shown in the drawing. In the front part of the device 1 is a parallel to the knife holding plate 4 insertable slide plate 8 is arranged, which is guided in a lateral groove in the frame strips 2 and is arranged in the engaged state so that between the rear portion of the slide plate 8 and a cutting knife 6, the is attached to the front edge of the knife holding plate 4, a narrow gap remains. The slide plate 8, on which the material to be cut is guided, also has longitudinal grooves 9 provided for this purpose.

In Fig. 2 ist die Anordnung von Messerklingen 10 und 12 des Schneidmessers 6 der bekannten Vorrichtung 1 in vergrößerter Darstellung gezeigt. Die gestrichelten Linien geben dabei jeweils eine Profilstufe 16 der Messerklingen 10 und 12 an, wobei die zu Schneidkanten 11 und 13 hin liegenden Bereiche der Messerklingen 10 und 12 höher liegen als die an die Umfangsränder 14 und 15 angrenzenden Bereiche. Die Profilstufen 16 bestehen dabei normalerweise aus Abschrägungen, wobei die durch diese Abschrägungen verbundenen Bereiche der Messerklingen parallel zueinander verlaufen.2 shows the arrangement of knife blades 10 and 12 of the cutting knife 6 of the known device 1 in an enlarged view. The dashed lines each indicate a profile step 16 of the knife blades 10 and 12, the areas of the knife blades 10 and 12 lying towards cutting edges 11 and 13 being higher than the areas adjacent to the peripheral edges 14 and 15. The profile steps 16 normally consist of bevels, the areas of the knife blades connected by these bevels running parallel to one another.

Bei der bekannten Vorrichtung wird eine V-Spitze 19 des Schneidmessers 6 dadurch gebildet, daß die beiden Messerklingen 12 und 13 bündig aneinanderstoßen, wobei ihre Halterung in der Messerhalteplatte 4 durch nietenartige, entsprechende Bohrungen 17 der beiden Messerklingen 10 und 12 durchsetzende Kunststoffnoppen erfolgt. Die Kunststoffnoppen werden im Spritzgußverfahren hergestellt.In the known device, a V-tip 19 of the cutting knife 6 is formed by the two knife blades 12 and 13 abutting each other, their mounting in the knife holding plate 4 through rivet-like, corresponding bores 17 of the two knife blades 10 and 12 penetrating plastic knobs. The plastic knobs are manufactured by injection molding.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Vorrichtung bezüglich ihrer Stabilität und damit ihrer Funktionsfähigkeit und Lebensdauer zu verbessern.The invention has for its object to improve the above-mentioned device in terms of its stability and thus its functionality and life.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Gegenstand der Unteransprüche sind bevorzugte Ausgestaltungen der Erfindung.According to the invention, this object is achieved by the features of claim 1. The subclaims relate to preferred embodiments of the invention.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus dem folgenden Ausführungsbeispiel, das anhand der beiliegenden Zeichnungen erläutert wird. Dabei zeigt:

Further advantages and features of the invention result from the following exemplary embodiment, which is explained with reference to the accompanying drawings. It shows:
Fig. 3
the device according to the invention in a schematic representation;
Fig. 4
the arrangement and design of the knife blades according to the invention in an enlarged view; and
Fig. 5
another embodiment of the knife blades according to the invention.

Fig. 3 zeigt eine ähnliche Darstellung wie Fig. 1. Ein wesentlicher Unterschied zwischen der erfindungsgemäßen Vorrichtung gemäß Fig. 3 und der Vorrichtung nach dem Stand der Technik gemäß Fig. 1 besteht in der unterschiedlichen Führung des Stufenprofils, das in beiden Zeichnungen mit den gestrichelten Linien auf den Messerklingen angedeutet ist. Bei der Vorrichtung nach dem Stand der Technik verlaufen diese Profilstufen geradlinig von einem Ende der Messerklinge zum anderen. Bei der erfindungsgemäßen Vorrichtung endet das jeweilige Profil an einer vorderen Seitenkante der Messerklinge vor der Rahmenleiste 2, während es am anderen Ende in einer Rundung ausläuft, so daß sich bei zusammengesetzten Messerklingen ein nahezu halbkreisförmiges Auslaufen des Stufenprofils am oberen Ende des V-förmigen Messers 6 ergibt.FIG. 3 shows a representation similar to FIG. 1. An essential difference between the device according to the invention according to FIG. 3 and the device according to the prior art according to FIG. 1 lies in the different guidance of the step profile, which is indicated by the dashed lines in both drawings Lines on the knife blades is indicated. In the device after State of the art, these profile steps run in a straight line from one end of the knife blade to the other. In the device according to the invention, the respective profile ends at a front side edge of the knife blade in front of the frame strip 2, while it ends in a curve at the other end, so that when the knife blades are assembled, an almost semicircular runout of the step profile at the upper end of the V-shaped knife 6 results.

Der Verlauf dieses Profils läßt sich noch einmal besonders deutlich in der vergrößerten Darstellung von Fig. 4 erkennen. Die Profilstufen 16 enden hier kurz vor Erreichen der Seitenkanten 20 der Messerklingen 10 und 12, wobei die den Schneidkanten 11 und 13 zugewandten Bereiche der Messerklingen höher liegen als die dem Umfangsrand 14, 15 zugewandten Bereiche. Dadurch wird eine weitere Entlastung der sensiblen V-Spitze 19 des Messers 6 gegen Schiebekräfte in der Schneidfläche erreicht, da die nicht von den Profilstufen 16 durchsetzten vorderen Seitenkanten 20 der Messerklingen 10, 12 sich nunmehr frei in den entsprechenden Schlitzen in den Rahmenleisten 2 verschieben können. Hierdurch wird das Auftreten von Schubkräften bei Temperaturschwankungen, zunächst beim Ausformen, später aber auch bei Reinigungsvorgängen mit heißem Wasser usw. zuverlässig vermieden, da durch die profilfreien Kanten 20 ein thermischer Ausgleich bei Schwindungen von Kunststoff und Metall möglich wird. Die formschlüssige Halterung der Messerklingen 10 und 12 des Schneidmessers 6 erfolgt in der angegebenen Weise zumindest im Bereich der V-Spitze 19 des Schneidmessers 6. Dabei ist in diesem Bereich ein Ansatz 18 der linken Messerklinge 12 vorgesehen, der gegenüber dem Hauptteil der Messerklinge 12 abgeknickt, abgeschrägt oder als Stufe ausgebildet ist, so daß er unter den dort befindlichen Abschnitt der rechten Messerklinge 10 zu liegen kommt. Zur weiteren Verbesserung der Halterung in diesem Bereich sind mindestens zwei Bohrungen 17 vorgesehen, von denen jeweils eine in einer der beiden Messerklingen 10 und 12 angeordnet ist. Die formschlüssig angespritzten Kunststoffstränge überlappen zumindest diesen Bereich der Messerklingen formschlüssig von beiden Seiten und durchgreifen dabei gleichzeitig die Bohrungen 17.The course of this profile can again be seen particularly clearly in the enlarged representation of FIG. 4. The profile steps 16 end here shortly before reaching the side edges 20 of the knife blades 10 and 12, the areas of the knife blades facing the cutting edges 11 and 13 being higher than the areas facing the peripheral edge 14, 15. This further relieves the sensitive V-tip 19 of the knife 6 against pushing forces in the cutting surface, since the front side edges 20 of the knife blades 10, 12 not penetrated by the profile steps 16 can now freely move in the corresponding slots in the frame strips 2 . This reliably prevents the occurrence of shear forces in the event of temperature fluctuations, first when molding, but later also during cleaning processes with hot water, etc., since the profile-free edges 20 make thermal compensation possible in the event of shrinkage of plastic and metal. The form-fitting holding of the knife blades 10 and 12 of the cutting knife 6 takes place in the specified manner at least in the area of the V-tip 19 of the cutting knife 6. In this area, an extension 18 of the left-hand knife blade 12 is provided, which kinks relative to the main part of the knife blade 12 , bevelled or designed as a step, so that it comes to rest under the section of the right knife blade 10 located there. To further improve the mounting in this area, at least two bores 17 are provided, one of which is arranged in one of the two knife blades 10 and 12. The positively molded plastic strands overlap at least this area of the knife blades in a form-fitting manner from both sides and at the same time pass through the bores 17.

Wie in Fig. 5 dargestellt, können alternativ auch in jeder Messerklinge 10, 12 Randaussparungen 21, 22 vorgesehen sein, die zusammen die Form einer einzigen länglichen Bohrung annehmen, welche dann von den Kunststoffträgern durchsetzt werden kann.As shown in FIG. 5, edge cutouts 21, 22 can alternatively also be provided in each knife blade 10, 12, which together take the form of a single elongated bore, which can then be penetrated by the plastic carriers.
