Beschreibungdescription
Hintergrund der ErfindungBackground of the invention
Die Erfindung betrifft eine Vorrichtung zum Zerteilen von Bearbeitungsgut, insbesondere zum Würfeln von Lebensmitteln, mit einem entlang eines Schneidgatters um eine Drehachse rotierenden Schneidwerkzeug, welches mittels mindestens einer Abstütz- einrichtung radial außen in axialer Richtung gestützt ist. Die Erfindung betrifft ferner eine damit ausgestattete Küchenmaschine.The invention relates to a device for cutting material to be processed, in particular for dicing foodstuffs, having a cutting tool which rotates about a rotation axis along a cutting gate and which is supported radially on the outside in the axial direction by means of at least one support device. The invention further relates to a food processor equipped therewith.
Stand der TechnikState of the art
Eine gattungsgemäße Vorrichtung zum Würfeln von Lebensmitteln, insbesondere von Obst und Gemüse, ist aus der deutschen Gebrauchsmusterschrift DE 203 14 247 U1 bekannt. Sie besteht aus einem ortsfest im Maschinengestell angeordneten Würfelgatter und einem zu diesem parallel rotierenden Messer. Das über einen Zuführschacht in die Vorrichtung eingeführte Bearbeitungsgut wird zunächst von dem Messer in Scheiben geschnitten, welche nachfolgend vom Messer durch das Würfelgatter gepresst wird. Das Messer ist balkenförmig ausgebildet und weist zwei Messerklingen auf, die spiegelbildlich zueinander angeordnet und mit der Antriebswelle der Vorrichtung verbunden sind.A generic device for dicing food, especially fruit and vegetables, is known from German Utility Model DE 203 14 247 U1. It consists of a stationary arranged in the machine frame cuboid and a parallel to this rotating knife. The material to be processed introduced into the device via a feed chute is first sliced by the knife, which is then pressed by the knife through the dice gate. The knife is bar-shaped and has two knife blades, which are arranged in mirror image to each other and connected to the drive shaft of the device.
Die Messerklingen bilden mit dem Würfelgatter einen sich bei Drehung des Messers verengenden Keilspalt aus, mittels dessen die zum Schneiden des Bearbeitungsguts im Würfelgatter erforderlich Axialkraft erzeugt wird. Die entsprechende Gegenkraft wird durch eine Abstützeinrichtung in Form von zwei sich zum Würfelgatter hin konisch verjüngenden Stützrollen aufgefangen, die im zuerst vom Messerbalken überstrichenen Bereich des Würfelgatters in Höhe des Außenumfangs des Messers angeordnet sind. Der komplementär zur den konischen Stützrollen geformte Außenumfang jeder Messerklinge läuft beim Betrieb der Vorrichtung je Umdrehung einmal in die Rolle ein, welche die auf das Messer wirkenden axialen, vom Würfelgatter weg gerichteten Reaktionskräfte aufnimmt und in das Maschinengestell ableitet. Hierdurch wird ein unzulässiges Verbiegen des Messers vermieden, welches zu einem ungleichmäßigen Bearbeitungsergebnis und zu einem Kontakt des Messers mit dem Zuführschacht führen kann. Über eine Klemmeinrichtung können die konischen Rollen in ihrer axialen Position relativ zum Maschinengestell eingestellt werden.The knife blades form with the cube gate a wedge gap narrowing when the blade rotates, by means of which the axial force required to cut the work piece in the cube gate is generated. The corresponding opposing force is absorbed by a supporting device in the form of two support rollers tapering conically towards the cube gate, which are arranged in the region of the cube gate swept first by the cutter bar at the level of the outer circumference of the blade. The complementary to the conical support rollers shaped outer circumference of each knife blade During operation of the device, once per revolution, it enters the roller, which picks up the axial forces acting on the blade away from the cube gate and discharges them into the machine frame. As a result, an impermissible bending of the knife is avoided, which can lead to an uneven machining result and to a contact of the knife with the feed chute. About a clamping device, the conical rollers can be adjusted in its axial position relative to the machine frame.
An dieser Vorrichtung kann nachteilig sein, dass die Messerklingen bei jeder Umdrehung gegen die konische Mantelfläche der Stützrollen laufen, wodurch die Geräuschemission der Vorrichtung erhöht wird. Darüber hinaus besteht die Gefahr, dass Bestandteile des Bearbeitungsguts beim Einlaufen der Messerklingen in die Stützrollen zwischen diese und den Außenumfang des Messers geraten. Bei falscher Einstellung der Stützrollen sind ein erhöhter Verschleiß oder sogar eine Beschädigung von Messer oder Abstützeinrichtung nicht ausgeschlossen.On this device may be disadvantageous that the knife blades run at each revolution against the conical surface of the support rollers, whereby the noise emission of the device is increased. In addition, there is a risk that components of the material to be processed when entering the knife blades in the support rollers between these and the outer circumference of the knife. If the support rollers are set incorrectly, increased wear or even damage to the knife or support device is not excluded.
Die deutsche Auslegeschrift DE 1 156 267 beschreibt eine ähnliche Maschine zum Schnitzeln von im Wesentlichen würfelförmigen Stücken aus Hackfrüchten oder dergleichen, bei der das Balkenmesser sichelförmig ausgebildet ist. Der radial außen liegende Umfang jeder Messerklinge ist zu einem Wulst mit rechteckigem Querschnitt verdickt. Die Wülste sind in einer inneren Radialnut des im Nutbereich geteilten Gehäuses geführt. Bei einem Verbiegen des Messers über ein vorgegebenes Maß hinaus ist somit grundsätzlich die Möglichkeit gegeben, dass sich die Wülste an der dem Würfelgatter abgewandten Axialfläche der Radialnut abstützen. Die Wülste sind ferner mit angeschrägten Frontflächen ausgestattet, welche beim Rotieren des Messers Bearbeitungsgut aus der Radialnut entfernen.German Auslegeschrift DE 1 156 267 describes a similar machine for chopping substantially cube-shaped pieces of root crops or the like, in which the bar knife is sickle-shaped. The radially outer periphery of each knife blade is thickened into a bead having a rectangular cross section. The beads are guided in an inner radial groove of the housing divided in the groove area. In a bending of the knife over a predetermined amount, in principle, there is the possibility that the beads are supported on the axial surface of the radial groove facing away from the cube gate. The beads are further equipped with tapered front surfaces, which remove machining material from the radial groove during rotation of the knife.
Auch bei dieser Ausführung kann die Gefahr eines erhöhten Verschleißes bestehen, insbesondere bei einer engen Passung zwischen den Wülsten und der Radialnut.Also in this embodiment, the risk of increased wear exist, especially with a tight fit between the beads and the radial groove.

Ein anders Wirkprinzip ist aus der Gebrauchsmusterschrift DE 20 2006 017 087 U1 bekannt. Dabei wird das Bearbeitungsgut, beispielsweise Fleisch, mittels eines Pressstempels durch eine Gattermessereinrichtung getrieben. Die Gattermessereinrichtung besteht aus einem ersten Führungsrahmen mit mehreren zueinander parallel ausgerichteten Gattermessern, welche in einer Ebene senkrecht zur Vorschubrichtung des Bearbeitungsguts linear hin- und her bewegt werden, wodurch das Bearbeitungsgut eingeschnitten wird. Die Gattermessereinrichtung ist ferner mit einem zweitenA different principle of action is known from the utility model DE 20 2006 017 087 U1. In this case, the material to be processed, for example meat, is driven by means of a ram through a Gattermessereinrichtung. The gate blade device consists of a first guide frame with a plurality of parallel aligned Gattermessern which are linearly reciprocated in a plane perpendicular to the feed direction of the Bearbeitungsguts, whereby the Bearbeitungsgut is cut. The gate meter device is further provided with a second one
Führungsrahmen ausgestattet, in welchem gleichfalls zueinander parallel beabstandete Gattermesser angeordnet sind. Diese bewegen sich, zu den ersten Gattermessern um 90° gedreht, gleichfalls in einer zur Vorschubrichtung senkrechten Ebene. Das Bearbeitungsgut wird von den Gattermessern stabartig geschnitten und nachfolgend von einem stromab des Gattermessers zu diesem parallel rotierenden Messer in Würfel getrennt. Lagerung sowie Aufbau des Messers sind in dieser Druckschrift nicht beziehungsweise nur andeutungsweise dargestellt.Fitted guide frame in which also parallel spaced gate blades are arranged. These move, rotated 90 ° to the first gate knives, also in a plane perpendicular to the feed direction. The processed material is cut rod-like by the Gattermessern and subsequently separated from a downstream of the Gattermessers to this parallel rotating knife into cubes. Storage and structure of the knife are not or only hinted at in this document.

Der Erfindung zugrundeliegende AufgabeThe problem underlying the invention
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zum Zerteilen von Bearbeitungsgut so weiter zu entwickeln, dass auch bei einem kostengünstigen Aufbau eine sichere Funktion, ein leiser Betrieb und eine einfache Handhabung ermöglicht werden, insbesondere für das Würfeln von weniger harten Lebensmitteln, beispielsweise Obst oder Gemüse. Die Vorrichtung soll dabei grundsätzlich auch zum Einsatz im für den Heimbereich vorgesehenen Küchenmaschinen geeignet sein.The invention has for its object to develop a generic device for cutting processed material so that even with a cost-effective design a safe function, quiet operation and ease of use are possible, especially for dicing less hard foods, such as fruit or vegetables.

Erfindungsgemäße LösungInventive solution
Die der Erfindung zugrunde liegende Aufgabe wird bei einer Vorrichtung der eingangs genannte Art dadurch gelöst, dass das Schneidwerkzeug mindestens ein Schneidmesser sowie einen im Bereich seines Außenumfangs vollständig umlaufenden, zur Anlage an die mindestens eine radial außen wirkende Abstützeinrichtung vorgesehenen Messerträger aufweist.The object underlying the invention is achieved in a device of the type mentioned above in that the cutting tool has at least one cutting blade and a fully circumferential in the region of its outer circumference, to bear against the at least one radially outwardly acting support means provided blade carrier.
Da die Abstützeinrichtung den umlaufenden Außenumfang des Messerträgers stützt, ist ein zyklisches und störungsanfälliges Einlaufen des Schneidwerkzeugs in die Abstütz- einrichtung nicht erforderlich. Das Schneidwerkzeug kann vielmehr in dem zugehörigen Vorrichtungsgehäuse positioniert werden, wodurch die Lage des Außenumfangs des Messerträgers relativ zu der mindestens einen Abstützeinrichtung im Wesentlichen festgelegt ist. Es ist durch die Erfindung erreichbar, dass der Außenumfang des Messerträgers beim Betreiben der Vorrichtung zwar an der oder den Abstützeinrichtungen entlang läuft, seine Lage gegenüber diesen insgesamt jedoch, von fertigungsbedingten Form- und Lageabweichungen sowie elastischen Verformungen abgesehen, nicht verändert. Hierdurch kann die Handhabung der Vorrichtung erheblich vereinfacht werden, da eine Justierung der Abstützeinrichtungen in der Regel nicht erforderlich ist oder zumindest erheblich vereinfacht wird. Infolge dessen können die Abstützeinrichtungen und die Vorrichtung insgesamt konstruktiv recht einfach gehalten werden, so dass die Vorrichtung nicht nur für den professionellen Einsatz geeignet ist. Durch das Wegfallen des zyklischen Einlaufens in die Abstützeinrichtung kann ferner der Geräuschpegel beim Betreiben der Vorrichtung gesenkt werden. Darüber hinaus ist erreichbar, dass dieSince the support device supports the circumferential outer circumference of the knife carrier, a cyclical and trouble-prone running of the cutting tool in the support device is not required. Rather, the cutting tool can be positioned in the associated device housing, whereby the position of the outer periphery of the blade carrier relative to the at least one support device is substantially fixed. It is achievable by the invention that the outer periphery of the knife carrier while operating the device while running on the or the support means along its position relative to these, however, apart from production-related shape and position deviations and elastic deformations, not changed. As a result, the handling of the device can be considerably simplified, since an adjustment of the support means is usually not required or at least considerably simplified. As a result, the support means and the device can be kept structurally quite simple overall, so that the device is not only suitable for professional use. By eliminating the cyclical shrinkage in the support device can also reduce the noise level Operating the device can be lowered. In addition, it is achievable that the
Vorrichtung problemlos und, bei geeigneter Werkstoffauswahl, auch in der Spülmaschine gereinigt werden kann.Device easily and, with a suitable choice of material, even in the dishwasher can be cleaned.
Bevorzugte Ausgestaltung der ErfindungPreferred embodiment of the invention
Vorteilhafte Aus- oder Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments or developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
Grundsätzlich ist es möglich, die Abstützung trotz umlaufenden Außenumfangs des Messerträgers auf die Bereiche des Schneidwerkzeugs zu beschränken, in denen die Schneidmesser angeordnet sind. Dies kann beispielsweise durch entsprechend angeordnete, stirnseitige Verdickungen des Außenumfangs erfolgen. Mit Vorteil ist die Anlage zwischen Messerträger und Abstützeinrichtung jedoch kontinuierlich vorgesehen, wodurch der Betrieb besonders leise und zuverlässig erfolgten kann.In principle, it is possible to limit the support, despite the circumferential outer circumference of the knife carrier, to the regions of the cutting tool in which the cutting blades are arranged. This can be done for example by appropriately arranged, frontal thickening of the outer periphery. Advantageously, however, the system between the knife carrier and supporting device is provided continuously, whereby the operation can be particularly quiet and reliable.
Mit besonderem Vorteil ist der Messerträger im Bereich der Drehachse mit einer Kupplungseinrichtung zur Einleitung eines Antriebsmoments versehen, welche einen zügigen und einfachen Wechsel des rotierenden Schneidwerkzeugs ermöglicht. Der konstruktive Aufbau und die Handhabung der Kupplungseinrichtung können insbesondere dadurch vereinfacht werden, dass die Axialkräfte zumindest anteilig über die Abstützeinrichtung in das Vorrichtungsgehäuse abgeleitet werden.With particular advantage, the knife carrier is provided in the region of the axis of rotation with a coupling device for introducing a drive torque, which allows a quick and easy change of the rotating cutting tool. The structural design and the handling of the coupling device can be simplified in particular by the fact that the axial forces are at least partially diverted via the support device into the device housing.
Bei einer bevorzugten Ausführung der Erfindung ist zur Verringerung von Materialaufwand und Gewicht des Schneidwerkzeugs vorgesehen, dass der Messerträger radial außen ein zur Anlage an die Abstützeinrichtung vorgesehenes Ringelement aufweist, welches den betreffenden Außenumfang ausbildet. Dieses Ringelement ist mit Vorteil durch das oder die ohnehin erforderlichen Schneidmesser mit der Kupplungseinrichtung verbunden, so dass der Aufbau des Schneidwerkzeugs nochmals vereinfacht werden kann.In a preferred embodiment of the invention, in order to reduce the material expenditure and the weight of the cutting tool, it is provided that the knife carrier has radially outwardly a ring element provided for abutment against the supporting device, which forms the respective outer circumference. This ring element is advantageously connected by the or required anyway cutting blade with the coupling device, so that the structure of the cutting tool can be further simplified.
Die Abstützeinrichtung ist nach einer besonders vorteilhaften Ausbildung der Erfindung zur axial gleitendreibenden Anlage an dem Messerträger des Schneidwerkzeugs vorgesehen. Durch den Verzicht auf rollreibende Wälzkörper werden der Aufbau der Vorrichtung kostengünstiger und deren Reinigung erleichtert. Die Gleitreibung wird durch entsprechende Materialpaarungen zwischen Messerträger und Abstützeinrichtung, beispielsweise die Verwendung von Kunststoffen wie Polyoxymethylen (POM) oder Polyamid (PA), gering gehalten, wobei sich Säfte aus dem Bearbeitungsgut nochmals reibmindernd auswirken.The support device is according to a particularly advantageous embodiment of the invention for axially slidably abutting the blade carrier of the cutting tool intended. By dispensing with rolling rolling elements, the structure of the device are cheaper and easier to clean. The sliding friction is kept low by appropriate material pairings between knife carrier and support device, for example, the use of plastics such as polyoxymethylene (POM) or polyamide (PA), with juices from the material to be processed again reduce friction.
Nach einer bevorzugten Ausführung ist die mindestens eine Abstützeinrichtung an einem Gehäuseteil vorgesehen, auf welches das Schneidwerkzeug drehbar aufsetzbar ist. Das Gehäuseteil kann beispielsweise eine zylindrische Form aufweisen, wobei der Messer- träger mit seinem Außenumfang auf der Stirnfläche dieses Zylinders aufliegt. In ein derartiges Gehäuseteil kann ferner ohne besonderen Aufwand ein zum Zwecke von Austausch oder Reinigung entnehmbares Schneidgatter eingesetzt werden.According to a preferred embodiment, the at least one support device is provided on a housing part, on which the cutting tool is rotatably mounted. The housing part may for example have a cylindrical shape, wherein the blade carrier rests with its outer periphery on the end face of this cylinder. In such a housing part can also be used without special effort a removable for the purpose of replacement or cleaning cutting gate.
Mit besonderem Vorteil weist die Abstützeinrichtung eine Anzahl von lösbaren Riegel- elementen auf, welche zum Umgreifen des Außenumfangs des Schneidwerkzeugs ausgebildet sind. Die axiale Sicherung des Schneidwerkzeugs kann durch diese Ausbildung besonders einfach realisiert werden. Darüber hinaus kann die Handhabung hierdurch einfacher und intuitiver gestaltet werden.With particular advantage, the support device has a number of releasable locking elements, which are designed to encompass the outer circumference of the cutting tool. The axial securing of the cutting tool can be particularly easily realized by this training. In addition, handling can be made simpler and more intuitive.
Konstruktiv bevorzugt ist dabei eine Ausführung, bei welcher der Außenumfang des Schneidwerkzeugs auf seiner dem Gehäuseteil abgewandten Axialfläche mit einem umlaufenden Wulst ausgestattet ist, der von den Riegelelementen rastend umgriffen wird. Zur Festlegung der Riegelelemente in ihrer Schließstellung sind keine weiteren Einrichtungen erforderlich. Die gilt insbesondere dann, wenn die Riegelelemente hakenförmig ausgebildet und tangential zum Umfang des Gehäuseteils schwenkbar mit diesem verbunden sind. Zur Vergleichmäßigung der Lastübertragung vom Schneidwerkzeug in das zugeordnete Gehäuseteil sind dabei vorzugsweise vier Riegelelemente gleichmäßig über den Umfang des Gehäuseteils verteilt angeordnet. Kurzbeschreibung der FigurenStructurally preferred is an embodiment in which the outer periphery of the cutting tool is provided on its side facing away from the housing part axial surface with a circumferential bead, which is encompassed by the locking elements latching. To fix the locking elements in their closed position no further facilities are required. This applies in particular when the locking elements are hook-shaped and tangentially connected to the circumference of the housing part pivotally connected thereto. To even out the load transfer from the cutting tool into the associated housing part, preferably four locking elements are distributed uniformly over the circumference of the housing part.

Ausführliche Beschreibung der Erfindung anhand zweier AusführungsbeispieleDetailed description of the invention with reference to two embodiments
Richtungs- und Lageangaben in der nachfolgenden Beschreibung beziehen sich auf die übliche, unter anderem in Fig. 2 gezeigte Einbau- und Betriebsstellung der Vorrichtung. Die in Fig. 1 und 2 dargestellte Vorrichtung 1 zum Würfeln von Lebensmitteln umfasst eine aus einer mit seitlichem Haltegriff 2 versehene, zylindrische Schüssel 3, die zum Aufsetzen auf eine nicht abgebildete Küchenmaschine vorgesehen ist. Die Küchenmaschine weist eine nach oben auskragende Antriebswelle auf, welche im Betrieb die Schüssel 3 im Bereich einer zentralen, hülsenartigen Ausnehmung 4 durchdringt.Direction and position information in the following description refers to the usual, shown in Fig. 2, for example installation and operating position of the device. The device 1 for dicing food shown in FIGS. 1 and 2 comprises a cylindrical bowl 3 provided with a lateral handle 2 and intended for placement on a food processor, not shown. The food processor has an upwardly projecting drive shaft, which in operation penetrates the bowl 3 in the region of a central, sleeve-like recess 4.
Auf den oberen Rand der Schüssel 3 ist ein Gehäuseteil 5 aufgesetzt, welches einerseits das dynamische Schneidwerkzeug 6 und andererseits das statische Schneidgatter 7 aufnimmt. Das Gehäuseteil 5 ist mit einem Deckel 8 verschließbar, welcher im Bereich des Schneidgatters 7 einen nach oben auskragenden Zuführschacht 9 für die Zufuhr des Bearbeitungsguts aufweist. Die nicht gezeigte Antriebswelle der Küchenmaschine ist in an sich bekannter Weise im oberen Bereich der Ausnehmung 4 zur Übertragung des Drehmoments formschlüssig in eine Kupplungseinrichtung 10 des Schneidwerkzeugs 6 eingelassen.On the upper edge of the bowl 3, a housing part 5 is placed, which on the one hand receives the dynamic cutting tool 6 and on the other hand, the static cutting gate 7. The housing part 5 can be closed with a lid 8, which in the region of the cutting gate 7 has an upwardly projecting feed chute 9 for the supply of the processed material. The drive shaft of the food processor, not shown, is inserted in a manner known per se in the upper region of the recess 4 for transmitting the torque in a form-fitting manner in a coupling device 10 of the cutting tool 6.
Das Gehäuseteil 5 ist, wie aus Fig. 3 und 4 ersichtlich, kreisscheibenförmig ausgebildet und mit einem exzentrisch angeordneten, näherungsweise rechteckigen Durchbruch 1 1 für den Durchtritt des Bearbeitungsguts versehen, welcher sich im unteren Bereich konisch verjüngt. Auf im sich verjüngenden Teil des Durchbruchs vorgesehene Stützrippen 12 ist das gleichfalls rechteckige Schneidgatter 7 flächenbündig mit derThe housing part 5 is, as shown in FIGS. 3 and 4, formed circular disk-shaped and provided with an eccentrically arranged, approximately rectangular opening 1 1 for the passage of the processed material, which tapers conically in the lower region. On provided in the tapered portion of the opening support ribs 12 is also rectangular cutting gate 7 flush with the
Oberseite 13 des Gehäuseteils 5 aufsetzbar. Im Gehäuseteil 5 befindet sich ferner mittig eine im Wesentlichen zylinderförmige, in Betriebsposition vertikale Bohrung 14, deren Mantelfläche bereichsweise in den Durchbruch 1 1 übergeht. Das Schneidgatter 7 weist aus diesem Grund eine der Mantelfläche folgende Einbuchtung 15 auf.Top 13 of the housing part 5 can be placed. In the housing part 5 is also centrally located a substantially cylindrical, in the operating position vertical bore 14, whose lateral surface partially merges into the opening 1 1. For this reason, the cutting gate 7 has a recess 15 following the lateral surface.
Die Bohrung 14 ist zur Aufnahme der hülsenartigen Kupplungseinrichtung 10 des Schneidwerkzeugs 6 vorgesehen, welche zum Aufsetzen auf die Antriebswelle der Küchenmaschine nach unten offen ausgebildet ist. Nach oben hin ist das Schneidwerkzeug 6 im Bereich der Kupplungseinrichtung 10 mit einem umlaufenden Kragen 16 und einem Stift 17 (siehe Fig. 2) versehen, welche koaxial zueinander sowie zur Drehachse der Antriebswelle angeordnet sind. Das Schneidwerkzeug 6 wird einerseits über die untere Mantelfläche der Kupplungseinrichtung 10 in der Bohrung 14 und andererseits mittels Kragen 16 beziehungsweise Stift 17 an einem nach unten auskragenden Ringvorsprung 18 des Deckels 8 radial drehgelagert.The bore 14 is provided for receiving the sleeve-like coupling device 10 of the cutting tool 6, which is designed to be open on the drive shaft of the food processor down. Towards the top, the cutting tool 6 is provided in the region of the coupling device 10 with a circumferential collar 16 and a pin 17 (see FIG. 2), which are arranged coaxially to one another and to the axis of rotation of the drive shaft. The cutting tool 6 is on the one hand on the lower surface of the coupling device 10 in the bore 14 and on the other hand by means of collar 16 or pin 17 radially rotatably mounted on a downwardly projecting annular projection 18 of the lid 8.
Das Schneidwerkzeug 7 ist ferner mit einem zur Drehachse koaxial ausgerichteten, im Bereich seines Außenumfangs vollständig umlaufenden Ringelement 19 ausgestattet, welches über zwei sich horizontal erstreckende, einander gegenüberliegendeThe cutting tool 7 is further equipped with a coaxially aligned to the axis of rotation, in the region of its outer circumference completely encircling ring member 19 which extends over two horizontally extending, opposite one another
Schneidmesser 20 mit dem oberen Teil der Kupplungseinrichtung 10 verbunden ist. Ringelement 19 und Kupplungseinrichtung 10 bilden somit gemeinsam einen Messerträger für das Schneidwerkzeug 6 aus. Die Schneidmesser 20 sind in üblicher Weise derart geneigt angeordnet, dass das vom Schneidwerkzeug 6 in Scheiben quergeschnittene Bearbeitungsgut bei dessen Rotation in Richtung des Pfeils A infolge Keilwirkung durch das Schneidgatter 7 getrieben und dort längsgeschnitten wird.Cutting knife 20 is connected to the upper part of the coupling device 10. Ring element 19 and coupling device 10 thus form together a knife carrier for the cutting tool 6. The cutting blades 20 are arranged inclined in a conventional manner such that the material to be cut transversely from the cutting tool 6 is driven through the cutting gate 7 during its rotation in the direction of the arrow A as a result of wedge action and is cut longitudinally there.
Entlang des Außenumfangs gleichmäßig verteilt sind am Gehäuseteil 5 Abstützeinrichtungen 21 in Form hakenartiger Riegelelemente 22 angeordnet, die an ihrem unteren Ende jeweils um eine vertikale, tangential zum Außenumfang des Gehäuseteils 5 ausgerichtete Drehachse 23 schwenkbar sind. In den Fig. 3 und 4 sind die Riegelelemente 22 in ihrer entriegelten Stellung abgebildet, während die nachfolgenden Fig. 5 und 6 diese in verriegeltem Zustand zeigen.Along the outer circumference are evenly distributed on the housing part 5 support means 21 are arranged in the form of hook-like locking elements 22 which are pivotable at its lower end in each case about a vertical tangential to the outer circumference of the housing part 5 oriented rotation axis 23. 3 and 4, the locking elements 22 are shown in their unlocked position, while the following FIGS. 5 and 6 show them in the locked state.
Bei der Inbetriebnahme der Vorrichtung 1 wird die Kupplungseinrichtung 10 in dieWhen commissioning the device 1, the coupling device 10 in the
Bohrung 14 eingeschoben, bis die untere Axialfläche 24 des Ringelements 19 auf der Oberseite 13 des Gehäuseteils 5 aufliegt. Nachfolgend werden die geöffneten Riegelelemente 22 durch ein zum Zentrum des Gehäuseteils 5 gerichtetes Schwenken mit ihrem oberen Horizontalschenkel 25 über die obere Axialfläche 26 des Ringelements 19 geschoben, bis diese aneinander anliegen. Die Riegelelemente 22 bilden mit dem Ringelement 19 dabei ein bistabiles System aus, welches infolge elastischer Verformung der Riegelelemente 22 sowie der in das Gehäuseteil 5 hinein versetzten Drehachsen 23 in verriegeltem Zustand eine Vorspannkraft in Verriegelungsrichtung erzeugt. Beim manuellen Lösen werden die Riegelelemente 22 nach dem Überwinden eines Totpunkts ohne weiteres Zutun mit einer in Richtung ihrer Entriegelungsposition wirkenden Gegenkraft beaufschlagt. Beim Betreiben einer mit der Vorrichtung 1 ausgestatteten Küchenmaschine entsteht infolge Schrägstellung der Schneidmesser 20 in Verbindung mit dem Widerstand des Schneidgatters 7 eine auf das Schneidwerkzeug 6 wirkende, nach oben gerichtete Axialkraft, welche von den Abstützeinrichtungen 21 in das Gehäuseteil 5 abgeleitet wird. Die Riegelelemente 22 dienen somit nicht nur dem Zusammenhalt von Schneidwerkzeug 6 und Gehäuseteil 5, vielmehr bilden Ringelement 19, Oberseite 13 des Gehäuseteils 5 und die Riegelelemente 22 miteinander ein geräuscharmes, einfach handzuhabendes und zu reinigendes Axiallager für das Schneidwerkzeug 6 aus.Inserted bore 14 until the lower axial surface 24 of the ring member 19 rests on the upper side 13 of the housing part 5. Subsequently, the open locking elements 22 are pushed by a directed to the center of the housing part 5 pivoting with its upper horizontal leg 25 on the upper axial surface 26 of the ring member 19 until they abut each other. The locking elements 22 form with the ring member 19 while a bistable system, which generates a biasing force in the locking direction due to elastic deformation of the locking elements 22 and the offset into the housing part 5 in rotational axes 23 in the locked state. When manually releasing the locking elements 22 are applied after overcoming a dead center without further action with an acting in the direction of its unlocking counter-force. When operating a kitchen appliance equipped with the device 1, an upward axial force, which acts on the cutting tool 6 and is deflected by the supporting devices 21 into the housing part 5, is produced as a result of inclination of the cutting blade 20 in conjunction with the resistance of the cutting gate 7. The locking elements 22 thus serve not only the cohesion of cutting tool 6 and housing part 5, but rather form ring member 19, top 13 of the housing part 5 and the locking elements 22 with each other a low-noise, easy-to-handle and to be cleaned thrust bearing for the cutting tool 6.
Bei der Ausführung nach Fig. 7 ist die obere Axialfläche 26 des Ringelements 19 des Schneidwerkzeugs 6 an dessen Außenumfang mit einem umlaufenden Wulst 27 versehen, welcher beim Schließen der Riegelelemente 22 rastend umgriffen wird. Der obere Horizontalschenkel 25 jedes Riegelelements 22 ist zu diesem Zweck mit einer den Wulst 27 in Verriegelungsstellung aufnehmenden Kröpfung 28 ausgestattet. Der Vorrichtung 1 ist ferner noch eine in Fig. 3 gezeigte Ausstoßeinrichtung 29 zugeordnet, die ein zum Schneidgatter 7 komplementäres Raster quaderförmiger Vorsprünge 30 sowie ein Griffstück 31 aufweist und zum manuellen Reinigen des Schneidgatters 7 benutzt werden kann.In the embodiment of Fig. 7, the upper axial surface 26 of the ring member 19 of the cutting tool 6 is provided on its outer periphery with a circumferential bead 27 which is encompassed latching when closing the locking elements 22. The upper horizontal leg 25 of each locking element 22 is equipped for this purpose with the bead 27 in the locking position receiving crank 28. The apparatus 1 is also associated with an ejector 29 shown in Fig. 3, which has a complementary to the cutting gate 7 grid of parallelepiped projections 30 and a handle 31 and can be used for manual cleaning of the cutting gate 7.
Gehäuseteil 5, Deckel 8 sowie Ringelement 19 und Kupplungseinrichtung 10 der Vorrichtung 1 sind bevorzugt durch Spritzgießen von Kunststoff hergestellt, wobeiHousing part 5, cover 8 and ring member 19 and coupling device 10 of the device 1 are preferably made by injection molding of plastic, wherein
Verschleiß und Reibwiderstand der aufeinander gleitenden Flächen durch eine geeignete Materialpaarung gering gehalten werden. Die Schneidmesser 20 können beispielsweise aus Metall gefertigt und radial außen und radial innen mit dem Werkstoff von Ringelement 19 und Kupplungseinrichtung 10 umspritzt werden. Alternativ ist angedacht, das komplette Schneidwerkzeug 6 wie auch das Schneidgatter 7 jeweils einstückig inWear and frictional resistance of the sliding surfaces are kept low by a suitable material pairing. The cutting blade 20 may be made of metal, for example, and radially outside and radially inwardly with the material of ring member 19 and coupling device 10 are encapsulated. Alternatively, it is envisaged that the complete cutting tool 6 as well as the cutting gate 7 in each case in one piece
