Description

Die Erfindung betrifft eine Vorrichtung zum Schneiden von Obst, Gemüse oder dergleichen in Scheiben, mit einer Messer­halteplatte, an deren Vorderkante ein V-förmiges Schneid­messer angeordnet ist, welches aus zwei Messerklingen be­steht; zwei im wesentlichen parallel angeordneten Rahmen­leisten, die durch die Messerhalteplatte und mindestens einen weiteren Quersteg miteinander verbunden sind; und einer an den Rahmenleisten geführten, parallel zur Messer­halteplatte einschiebbaren Schieberplatte, wobei zwischen der hinteren Kante der Schieberplatte und dem Schneidmesser ein schmaler Spalt verbleibt.The invention relates to a device for cutting fruit, vegetables or the like into slices, with a knife holding plate, on the front edge of which a V-shaped cutting knife is arranged, which consists of two knife blades; two frame strips arranged essentially in parallel, which are connected to one another by the knife holding plate and at least one further crosspiece; and a slide plate guided on the frame strips and insertable parallel to the knife holding plate, a narrow gap remaining between the rear edge of the slide plate and the cutting knife.

Eine derartige Vorrichtung ist beispielsweise aus der EP 0 306 017 A2 bekannt, wobei allerdings das dort verwendete V-förmige Schneidmesser einstückig ausgebildet ist, was insbesondere fertigungstechnisch ungünstig ist.Such a device is known for example from EP 0 306 017 A2, although the V-shaped cutting knife used there is formed in one piece, which is particularly disadvantageous in terms of production technology.

Der Stand der Technik, von dem die vorliegende Erfindung ausgeht, ist in den Zeichnungen anhand der Figuren 1 und 2 aufgezeigt, wobei Fig. 1 in schematischer Darstellung eine Vorrichtung nach dem Oberbegriff von Anspruch 1 zeigt, wie sie von der Amelderin bereits seit einiger Zeit vertrieben wird. Fig. 2 zeigt in vergrößerter Darstellung die ent­sprechende Anordnung der Messerklingen in der Vorrichtung nach Fig. 1.The state of the art, from which the present invention is based, is shown in the drawings with reference to FIGS. 1 and 2, FIG. 1 schematically showing a device according to the preamble of claim 1, as has been used by the Amelder for some time is distributed. FIG. 2 shows an enlarged representation of the corresponding arrangement of the knife blades in the device according to FIG. 1.

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 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 additionally provided with 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 Profil­ stufen 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 stages 16 usually 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 one another, their mounting in the knife holding plate 4 being carried out by rivet-like, corresponding bores 17 of the two knife blades 10 and 12 penetrating plastic knobs. The plastic knobs are manufactured by injection molding.

Die bekannte Vorrichtung ist insofern nachteilig, als es sehr schwierig ist, die beiden Messerklingen genau auf einer Schneidebene zu halten, so daß beim Überschreiten bestimmter Schneidkräfte, z. B. beim Schneiden verhältnismäßig harter Gegenstände, ein Aufheben der Messerklingen unausweichlich ist. Eine entsprechende Verschiebung der beiden Messerklingen gegeneinander verstärkt sich dann im Laufe der Zeit immer mehr und führt schließlich zu einem Unbrauchbarwerden der gesamten Vorrichtung.The known device is disadvantageous in that it is very difficult to keep the two knife blades exactly on a cutting plane, so that when certain cutting forces, e.g. B. when cutting relatively hard objects, picking up the knife blades is inevitable. A corresponding displacement of the two knife blades against each other then increases more and more over time and ultimately leads to the entire device becoming unusable.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die bekannte Vorrichtung dahingehend weiterzubilden, daß eine zuverlässige Halterung der Messerklingen zu gewährleisten, um so die Funktionsfähigkeit und Lebensdauer der Vorrichtung insgesamt zu verbessern.The present invention is therefore based on the object of developing the known device to ensure that the knife blades are held reliably in order to improve the overall functionality and service life of the device.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Umfangsrand der Messerklingen zumindest in ihrem hinteren, an die V-Spitze des Schneidmessers angrenzenden Bereich formschlüssig von angespritzten Kunststoffsträngen in Form eines liegenden U-Profils gehalten wird. Durch diese Ausge­staltung der Halterung der Messerklingen in der Messerhalte­platte können das bisher auf Dauer unvermeidliche Aufheben der Klingen und daraus entstehende Fehlstellen in der gemein­samen Schnittebene zuverlässig vermieden werden.According to the invention, this object is achieved in that the peripheral edge of the knife blades is held in a form-fitting manner by injection-molded plastic strands in the form of a lying U-profile, at least in its rear area adjacent to the V-tip of the cutting knife. This configuration of the mounting of the knife blades in the knife holding plate makes it possible to reliably avoid the lifting of the blades, which has hitherto been inevitable in the long run, and the resulting defects in the common cutting plane.

In einer besonderen Ausführungsform der Erfindung gehen die angespritzten Kunststoffstränge vollständig in die Kunst­stoffmasse der Messerhalteplatte über und durchsetzen gleich­zeitig den hinteren Bereich der Messerklingen an mindestens einer Stelle. Dabei ist es besonders bevorzugt, daß im hin­teren Bereich jeder Messerklinge entweder mindestens eine separate Bohrung vorgesehen ist oder jeweils eine Randaus­sparung, wobei die Randaussparungen nach Zusammenbau der Messerklingen zum Schneidmesser zusammen die Form einer einzigen länglichen Bohrung aufweisen. Die Kunststoffstränge verhindern dadurch sowohl ein Ausweiten des U-Profils und damit ein Lockern des Formschlusses, gewährleisten darüber hinaus aber auch noch eine exakte Sicherung der Messerklingen gegen eine Verschiebung in der Ebene der Schneidfläche.In a special embodiment of the invention, the molded plastic strands completely merge into the plastic mass of the knife holding plate and at the same time penetrate the rear region of the knife blades at at least one point. It is particularly preferred that either at least one separate hole is provided in the rear area of each knife blade or one edge cutout each, the edge cutouts having the shape of a single elongated hole together after the knife blades have been assembled to form the cutting knife. The plastic strands thus prevent the U-profile from expanding and thus loosening the positive locking, but also ensure that the knife blades are precisely secured against displacement in the plane of the cutting surface.

Eine weitere Ausführungsform der Erfindung schlägt vor, daß die Messerklingen so angeordnet sind, daß wenigstens ein Ansatz der einen Messerklinge zumindest teilweise unter der anderen Messerklinge liegt, wobei besagter Ansatz gegenüber dem Hauptteil der einen Messerklinge abgeknickt, abgeschrägt, als Stufe ausgebildet oder in ähnlicher Weise ausgeformt ist. Durch diese erfindungsgemäße Maßnahme wird einer Auf­weitung der Messerklingen im Bereich der Messerspitze zu­sätzlich wirkungsvoll entgegengewirkt, wobei durch die ent­sprechende Abknickung, Stufenausbildung oder Abschrägung der unten liegenden Messerklinge gewährleistet ist, daß die Schneidflächen der Messerklingen tatsächlich exakt in einer Ebene liegen und dort auch zuverlässig verbleiben.A further embodiment of the invention proposes that the knife blades are arranged in such a way that at least one attachment of one knife blade lies at least partially below the other knife blade, said attachment being kinked, beveled, designed as a step or similar in relation to the main part of the one knife blade is formed. This measure according to the invention additionally effectively counteracts a widening of the knife blades in the area of the knife tip, whereby the corresponding kinking, step formation or beveling of the knife blade located below ensures that the cutting surfaces of the knife blades actually lie exactly in one plane and also remain there reliably.

Die Erfindung sieht weiterhin vor, daß die Messerklingen ein Profil mit einer Stufe aufweisen, das im hinteren, an die Messerspitze angrenzenden Bereich der Messerklingen so ab­gerundet ist, daß sich bei zusammengesetzten Messerklingen eine nahezu halbkreisförmige Profilführung ergibt. Durch diese besondere Ausgestaltung des hinteren Bereichs der Messerklingen wird eine besonders feste Halterung derselben durch die angespritzten Kunststoffstränge im besonderen sensiblen Bereich der V-Spitze des Schneidmessers möglich, da der gesamte Umfangsrand formschlüssig umgriffen werden kann.The invention further provides that the knife blades have a profile with a step which is rounded in the rear area of the knife blades adjacent to the tip of the knife so that an almost semicircular profile guidance results when the knife blades are assembled. This special design of the rear area of the knife blades makes it particularly firm due to the molded plastic strands in the particularly sensitive area of the V-tip of the cutting knife, since the entire circumferential edge can be encompassed in a form-fitting manner.

Erfindungsgemäß wird somit eine gattungsgemäße Vorrichtung zur Verfügung gestellt, deren Messerklingen besonders sicher und fest in der Messerhalteplatte gehalten werden und bei der selbst bei hohen mechanischen und thermischen Belastungen sichergestellt ist, daß die Schneidflächen der Messerklingen zuverlässig in einer Ebene verbleiben. Zusätzlich ist an­zumerken, daß die erfindungsgemäß zur Anwendung kommenden Spritzgußtechniken besonders leicht zu führen sind, da kein Kernzug zum Entformen notwendig ist.According to the invention, a generic device is thus made available, the knife blades of which are held particularly securely and firmly in the knife holding plate and which ensures that the cutting surfaces of the knife blades remain reliably in one plane, even under high mechanical and thermal loads. In addition, it should be noted that the injection molding techniques used according to the invention are particularly easy to use, since no core pull is necessary for demolding.

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

  • Fig. 3 die erfindungsgemäße Vorrichtung in schematischer Darstellung;
  • Fig. 4 die Anordnung und Ausgestaltung der erfindungs­gemäßen Messerklingen in vergrößerter Darstel­lung; und
  • Fig. 5 eine andere Ausgestaltung der erfindungsgemäßen Messerklingen.
Further advantages and features of the invention result from the following exemplary embodiment, which is explained with reference to the accompanying drawings. It shows:
  • Figure 3 shows the device according to the invention in a schematic representation.
  • 4 shows the arrangement and configuration of the knife blades according to the invention in an enlarged representation; and
  • 5 shows 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 Messer­ klinge 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 according to the prior art, these profile steps run straight from one end of the knives blade to another. 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 at the other end it ends in a curve, 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 Messer­ klingen 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 illustration in 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 which are 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 case of temperature fluctuations, initially during molding, but later also during cleaning processes with hot water, etc., since the profile-free edges 20 enable thermal compensation in the event of plastic and metal shrinkage. 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 bends towards the main part of the knife blade 12 , beveled 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 molded plastic strands overlap at least this area of the knife sound form-fitting from both sides and reach through the holes 17 at the same time.

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.

Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the drawings and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments.
