Description

Die Erfindung betrifft einen Allesschneider nach dem Oberbegriff des Patentanspruches 1 so wie er gattungsbildend beispielsweise aus der US 5,934,143 A oder der DE 44 32 973 A bekannt ist. Gegenstand der Erfindung ist insbesondere die Ausbildung der Antriebseinheit für den Allesschneider.The invention relates to a slicer according to the preamble of claim 1 as it is generic, for example from US 5,934,143 A or DE 44 32 973 A is known. The invention is particularly the formation of the drive unit for the food slicer.

Aus der DE 82 17 628 U1 ist eine Antriebseinheit für einen Allesschneider bekannt. Die bekannte Antriebseinheit für einen Allesschneider umfasst einen Elektromotor, der in einem schalenförmigen Gehäuse untergebracht ist und dessen Motorachse in eine Antriebsschnecke ausläuft, welche über ein Getriebe eine Messerscheibe antreibt. Die Messerscheibe ist mittels einer Haltescheibe und einem Gewindeteil an eine Lagerwelle geschraubt, die in einem Stützauge des Gehäuses befestigt ist. Der Elektromotor und ein mit der Motorwelle in Eingriff stehendes Antriebszahnrad sind auf einer Lagerplatte festgelegt. Die Lagerplatte ist durch Schrauben mit dem Gehäuse verbunden.From DE 82 17 628 U1 a drive unit for a food slicer is known. The known drive unit for a food slicer comprises an electric motor which is housed in a cup-shaped housing and whose motor axis terminates in a drive screw, which drives a knife disc via a gear. The knife disc is screwed by means of a retaining washer and a threaded part to a bearing shaft which is fixed in a support eye of the housing. The electric motor and a drive gear meshing with the motor shaft are fixed on a bearing plate. The bearing plate is connected by screws to the housing.

Nachteilig an dieser bekannten Antriebseinheit für einen Allesschneider ist, dass die Messerscheibe im Gehäuse gelagert ist und die Antriebseinheit auf einer vom Gehäuse getrennten Lagerplatte befestigt ist. Bei der Montage der Antriebseinheit ist dort besonders darauf zu achten, dass die Lagerplatte, auf der sich die Antriebseinheit befindet, bzgl. der Lagerung der Messerscheibe ausgerichtet werden muss. Insbesondere wenn der elastische Zahnriemenantrieb durch einen Direktantrieb ersetzt werden soll, sind enge Einbautoleranzen zwischen Lagerplatte und Lagerung der Messerscheibe einzuhalten.A disadvantage of this known drive unit for a food slicer that the cutter disk is mounted in the housing and the drive unit is mounted on a separate bearing plate from the housing. When installing the drive unit, special care must be taken there that the bearing plate on which the drive unit is located must be aligned with respect to the bearing of the knife disk. In particular, when the elastic toothed belt drive to be replaced by a direct drive, tight installation tolerances between the bearing plate and storage of the cutting disc must be followed.

Schließlich sei noch auf die DE 807 578 C, die DE 197 04 110 A sowie die US 5,298,821 A hingewiesen.Finally, attention should be drawn to DE 807 578 C, DE 197 04 110 A and US 5,298,821 A.

Der Erfindung liegt die Aufgabe zugrunde, einen Allesschneider zu schaffen, der eine vereinfachte Antriebseinheit aufweist. Insbesondere soll die Montage der Antriebseinheit vereinfacht werden. Des weiteren ist es Aufgabe der Erfindung eine Antriebseinheit für einen Allesschneider zu schaffen, die besonders leise arbeitet. Eine zusätzliche Aufgabe ist es, trotz vereinfachter Antriebseinheit die Lebensdauer des Allesschneiders zu erhöhen.The invention has for its object to provide a food slicer, which has a simplified drive unit. In particular, the assembly of the drive unit should be simplified. Furthermore, it is an object of the invention to provide a drive unit for a slicer that works very quiet. An additional task is to increase the lifetime of the food slicer despite the simplified drive unit.

Diese Aufgabe wird mit einem Allesschneider mit den Merkmalen des Anspruchs 1 gelöst. Durch die Integration des Lagers für das Rundmesser in die Lagerplatte, welche auch die Lagerstellen des Getriebes aufweist, ergibt sich eine kompakte Bauweise der Antriebseinheit. Ein weiterer Vorteil ist die Reduzierung der Teileanzahl. Die reduzierte Teileanzahl ermöglicht eine kostengünstige Fertigung und eine einfachere Montage. Die besonders steife Verbindung von Getriebe und Lager des Rundmessers ermöglicht es, enge Einbautoleranzen vorzusehen, wodurch sich ein sehr leiser Antrieb ergibt. Durch eine erhöhte Form- und Lagesteifigkeit der Getriebe- und Lagerverbindung können die Achsabstände genauer eingehalten werden, wodurch sich eine geringere Abnutzung der Zahnräder ergibt und sich die Lebensdauer erhöht.This object is achieved with a slicer with the features of claim 1. By integrating the bearing for the circular blade in the Bearing plate, which also has the bearing points of the transmission, results in a compact design of the drive unit. Another advantage is the reduction in the number of parts. The reduced number of parts allows cost-effective production and easier installation. The particularly rigid connection of gear and bearing of the circular blade makes it possible to provide tight installation tolerances, resulting in a very quiet drive. Due to an increased form and positional rigidity of the gear and bearing connection, the center distances can be maintained more accurately, resulting in less wear of the gears and increases the life.

In einer vorteilhaften Ausgestaltung sind an der Innenseite des Gehäuses Rastnasen angeformt, durch die das Lager des Rundmessers zur Öffnung des Gehäuses positioniert und fixiert ist. Die Lagerplatte ist dadurch über eine lösbare Schnappverbindung an der Innenseite des Gehäuses befestigt. Bei der Montage des Allesschneiders muss lediglich die vormontierte Baueinheit, welche durch Getriebe, Lagerplatte und erstem Lager des Rundmessers gebildet wird, an die Schnappverbindung an der Innenseite des Gehäuse angedrückt werden, um die komplette Antriebseinheit am Gehäuse des Allesschneiders zu befestigen. Dies hat den Vorteil, dass keine zusätzlichen Arbeitsschritte für die Befestigung notwendig sind und auf zusätzliche Befestigungsmittel verzichtet werden kann. Insbesondere können Schrauben oder ähnliche lösbare Befestigungsmittel eingespart werden. Zur Ausbildung der Lagerplatte kann besonders formsteifer Werkstoff mit Lagerqualitäten verwandt werden.In an advantageous embodiment, locking lugs are integrally formed on the inside of the housing, through which the bearing of the circular blade is positioned and fixed to the opening of the housing. The bearing plate is thereby secured via a releasable snap connection on the inside of the housing. When installing the food processor only the preassembled unit, which is formed by gear, bearing plate and the first bearing of the circular blade to be pressed against the snap connection on the inside of the housing to secure the complete drive unit to the housing of the food slicer. This has the advantage that no additional steps for the attachment are necessary and can be dispensed with additional fasteners. In particular, screws or similar releasable fastening means can be saved. To form the bearing plate can be used with dimensionally stable material particularly rigid material.

Die Rastnasen können im Nahbereich der Öffnung des Gehäuses befestigt sein. Am Rand der Öffnung des Gehäuses, durch welche die Drehachse des Rundmessers läuft, können beispielsweise drei um 120° versetzte Rastnasen angeformt sein, die drei zugeordnete Rastnuten am ersten Lager der Lagerplatte hintergreifen und dadurch die Lagerplatte an der Innenseite des Gehäuses fixieren. Diese Befestigungsart ist nicht nur besonders großseriengerecht, sondern garantiert gleichzeitig auch noch eine besonders genaue und lagesichere Zuordnung des Lagers für das Rundmesser zur Öffnung. Die Ausbildung der Schnappverbindungen, bzw. der Rastnasen an dem Gehäuse hat den Vorteil, dass die Teilevielfalt reduziert ist. Da die Lagerplatte bevorzugter Weise aus einem sehr steifen Material ausgebildet sein soll und das Gehäuse aus einem relativ weichen Material bestehen kann, ist es sinnvoll die Schnappverbindung bzw. die Rastnasen insbesondere am Gehäuse anzuformen, da das weichere Material des Gehäuses eine gewisse Elastizität der Schnappverbindung ermöglicht.The locking lugs can be fastened in the vicinity of the opening of the housing. At the edge of the opening of the housing, through which passes the axis of rotation of the circular blade, for example, three offset by 120 ° locking lugs may be formed, engage behind the three associated locking grooves on the first bearing of the bearing plate and thereby fix the bearing plate on the inside of the housing. This type of attachment is not only particularly suitable for mass production, but at the same time guarantees a particularly accurate and secure assignment of the bearing for the circular blade to the opening. The formation of the snap connections, or the latching lugs on the housing has the advantage that the variety of parts is reduced. Since the bearing plate should preferably be formed of a very rigid material and the housing may consist of a relatively soft material, it makes sense to mold the snap connection or the detents, in particular on the housing, since the softer material of the housing allows a certain elasticity of the snap connection.

In einer bevorzugten Ausführungsform ist das erste Lager des Rundmessers als Narbe ausgebildet, in der ein Lagerzapfen lösbar befestigt ist, auf dem das Rundmesser drehbar gelagert ist. Damit das Rundmesser leicht gereinigt werden kann, ist dieses lösbar mit dem Antrieb des Allesschneiders verbunden. Zur Befestigung des Rundmessers an der Antriebseinheit wird das Rundmesser über seine zentrale Öffnung auf den Lagerzapfen aufgesetzt und es ist auf diesem drehbar gelagert. Der Lagerzapfen wird zusammen mit dem aufgesetzten Rundmesser in die Narbe des ersten Lagers eingeführt und in dieser arretiert. Das Rundmesser ist auf dem Lagerzapfen frei drehbar und gleichzeitig in bezug auf die Antriebseinheit exakt positioniert. Da die Lagerplatte sowohl das Getriebe als auch das drehbar gelagerte Rundmesser trägt, ergibt sich ein sehr stabiler Aufbau der gesamten Antriebseinheit von Motorgetriebe und Rundmesser.In a preferred embodiment, the first bearing of the circular blade is formed as a scar, in which a bearing pin is releasably secured, on which the circular blade is rotatably mounted. In order for the circular blade to be easily cleaned, it is detachably connected to the drive of the food slicer. To attach the rotary blade to the drive unit, the circular blade is placed over its central opening on the bearing journal and it is rotatably mounted on this. The journal is inserted together with the attached circular blade in the scar of the first bearing and locked in this. The circular blade is freely rotatable on the journal and at the same time accurately positioned with respect to the drive unit. Since the bearing plate carries both the gear and the rotatably mounted circular blade, there is a very stable structure of the entire drive unit of motor gear and circular blade.

In einer bevorzugten Ausführungsform weist die Lagerplatte ein zweites Lager auf, das in einem Abstand zum ersten Lager des Rundmessers angeordnet ist und dieses zweite Lager das Getriebe trägt. Dadurch wird ein Getriebeaufbau realisiert, der einen sehr flachen Aufbau ermöglicht, d.h. der gesamte Allesschneider kann in einer sehr geringen Breite realisiert werden.In a preferred embodiment, the bearing plate on a second bearing, which is arranged at a distance from the first bearing of the circular blade and this second bearing carries the gearbox. As a result, a gear structure is realized, which allows a very flat structure, i. The entire food slicer can be realized in a very small width.

In einer vorteilhaften Variante umfasst das Getriebe ein Antriebszahnrad, welches mit einem Abtriebszahnrad gekoppelt ist, das in einem am Rundmesser befestigten Zahnkranz eingreift. Erfolgt der Antrieb des Rundmessers nicht direkt an dessen Drehachse, sondern möglichst weit außen in Nähe des Außenumfangs des Rundmessers, kann ein dort befestigter Zahnkranz in seinem Durchmesser relativ groß ausgebildet sein und das Abtriebszahnrad, weiches in den Zahnkranz eingreift, kann möglichst im Durchmesser klein ausgebildet sein, wodurch sich der Vorteil ergibt, dass in einer Getriebestufe eine möglichst hohe Übersetzung erreicht werden kann und das Rundmesser mit einer geringen Drehzahl aber mit einem hohen Drehmoment betrieben werden kann. Die Verwendung von schrägverzahntem Zahnkranz und Abtriebszahnrad hat den weiteren Vorteil, dass ein weitgehend spielfreier Antrieb ermöglicht wird.In an advantageous variant, the transmission comprises a drive gear, which is coupled to an output gear, which engages in a toothed ring attached to the circular blade. If the drive of the circular blade is not directly on the axis of rotation, but as far as possible outside near the outer periphery of the circular blade, a ring gear fixed there may be formed relatively large in diameter and the driven gear, soft engages the ring gear, can be made as small as possible in diameter be, resulting in the advantage that in a gear stage the highest possible translation can be achieved and the circular blade can be operated with a low speed but with a high torque. The Use of helical sprocket and driven gear has the further advantage that a largely backlash-free drive is possible.

Das Antriebszahnrad und das Abtriebszahnrad können drehfest miteinander verbunden sein. Insbesondere ist es von Vorteil, wenn das Antriebszahnrad und das Abtriebszahnrad aus einem Stück gefertigt sind. Dadurch reduziert sich die Teilevielfalt und eine möglichst steife Verbindung von Antriebszahnrad und Abtriebszahnrad wird ermöglicht. So kann in sehr kompakter Bauweise ein Getriebe realisiert werden, welches zwei Getriebestufen aufweist.The drive gear and the output gear can be rotatably connected to each other. In particular, it is advantageous if the drive gear and the output gear are made in one piece. This reduces the variety of parts and a possible stiff connection of drive gear and output gear is possible. Thus, in a very compact design, a gear can be realized, which has two gear stages.

Erfindungsgemäß ist an der Lagerplatte ein Flansch angeformt, gegen den der Antriebsmotor durch Halteelemente mit elastischen Eigenschaften positioniert ist. Der Motor ist mittels derartiger Halteelemente direkt an die Lagerplatte angeflanscht, welche das Getriebe trägt. Der Motor ist somit nicht am Gehäuse des Allesschneiders befestigt, sondern der Motor ist an der Lagerplatte befestigt und die Lagerplatte an einer Innenseite des Gehäuses fixiert. Dies hat den Vorteil, dass nicht nur Getriebe und Lagerplatte eine Baueinheit bilden, sondern auch der Antriebsmotor in die Baueinheit bestehend aus Getriebe und Lagerplatte mitintegriert ist. Dies hat den Vorteil, dass eine gesonderte Befestigung des Antriebsmotors an dem Gehäuse des Allesschneiders entfallen kann. Dies erleichtert die Montage und es kann auf zusätzliche Befestigungsmittel verzichtet werden.According to the invention, a flange is formed on the bearing plate, against which the drive motor is positioned by holding elements with elastic properties. The motor is flanged by means of such holding elements directly to the bearing plate, which carries the gearbox. The motor is thus not attached to the housing of the food slicer, but the motor is fixed to the bearing plate and the bearing plate fixed to an inner side of the housing. This has the advantage that not only gear and bearing plate form a structural unit, but also the drive motor in the assembly consisting of gear and bearing plate is mitintegriert. This has the advantage that a separate attachment of the drive motor to the housing of the food slicer can be omitted. This facilitates the assembly and it can be dispensed with additional fasteners.

Die Halteelemente mit elastischen Eigenschaften können als federnde Rasthaken ausgebildet sein, deren Haltenasen in Öffnungen am Motorgehäuse eingreifen. Das so ausgebildete Befestigungsmittel befestigt den Antriebsmotor am Flansch der Lagerplatte indem es den das Motorgehäuse in axialer Richtung gegen den Flansch drückt.The holding elements with elastic properties can be designed as resilient latching hooks whose retaining lugs engage in openings on the motor housing. The fastener thus formed secures the drive motor to the flange of the bearing plate by pressing the motor housing in the axial direction against the flange.

Vorzugsweise sind wenigstens zwei Rasthaken vorgesehen, die an der Lagerplatte bzw. an dem Flansch einander gegenüberliegend angeformt, wobei zwischen Rasthaken und Flansch ein elastischer Abschnitt ausgebildet sein kann. Dadurch wird der Motor in axialer Richtung gegen die Lagerplatte bzw. gegen den Flansch federnd vorgespannt. Durch die elastischen Abschnitte können Form- und Lagetoleranzen des Antriebsmotors und der Öffnungen am Motorgehäuse ausgeglichen werden.Preferably, at least two latching hooks are provided, which are formed opposite one another on the bearing plate or on the flange, wherein an elastic portion can be formed between the latching hook and the flange. As a result, the motor is resiliently biased in the axial direction against the bearing plate or against the flange. Through the elastic sections Form and position tolerances of the drive motor and the openings on the motor housing can be compensated.

In einer bevorzugten Ausführungsform trägt der Antriebsmotor auf seiner Motorachse eine Schnecke, die mit dem Antriebszahnrad in Eingriff ist. Schnecke und Antriebszahnrad bilden eine erste Getriebestufe mit einer hohen Übersetzung. Das Antriebszahnrad bildet vorzugsweise mit dem Abtriebszahnrad eine Einheit. Abtriebszahnrad und Zahnkranz des Rundmessers bilden eine zweite Getriebestufe, die ebenfalls eine hohe Übersetzung aufweist. Damit wird ein zweistufiges Getriebe mit sehr hoher Übersetzung ermöglicht. Dies hat den Vorteil, dass ein relativ kleiner Antriebsmotor mit großer Drehzahl verwendet werden kann, und das Rundmesser mit sehr geringer Drehzahl aber hohem Drehmoment betrieben wird.In a preferred embodiment, the drive motor carries on its motor axis a worm, which is in engagement with the drive gear. Worm and drive gear form a first gear with a high gear ratio. The drive gear preferably forms a unit with the output gear. Output gear and ring gear of the circular blade form a second gear, which also has a high gear ratio. This allows a two-stage gearbox with very high gear ratio. This has the advantage that a relatively small drive motor can be used at high speed, and the rotary blade is operated at very low speed but high torque.

Vorteilhafter Weise ist das Schneckenrad des Antriebsmotors nach der Montage des Antriebsmotors auf die Motorachse direkt aufgerollt. Die bekannten Antriebsmotoren für Allesschneider weisen üblicherweise eine Motorachse auf, die einen Absatz aufweist, an der eine gesonderte Schnecke aufgepresst oder aufgeschrumpft ist. Erfindungsgemäß weist der vormontierte Antriebsmotor eine Motorachse ohne Absatz auf. Nach der Montage des Antriebsmotors wird dann eine Schnecke direkt auf die glatte Welle aufgerollt. Dies reduziert die Fertigungskosten. Durch das Aufrollen der Schnecke auf eine glatte Motorachse kann insbesondere auf den Arbeitsgang der Herstellung eines Absatzes auf der Motorachse verzichtet werden, da kein Absatz auf der Motorachse nötig ist. Bei den bekannten Antriebsmotoren ist hingegen ein Wellenabsatz nötig, um einen Sitz für die gesonderte Schnecke zu bilden. Bei den bekannten Antriebsmotoren ist zudem die gesonderte Schnecke spanend gefertigt, was ein relativ kostenintensiver Fertigungsschritt ist. Des weiteren muss die gesonderte Schnecke auf die Motorachse des Antriebsmotors montiert werden. Im Gegensatz dazu ist das Aufrollen der Schnecke auf eine glatte Motorachse kostengünstiger und ein Montageschritt kann entfallen.Advantageously, the worm wheel of the drive motor is directly rolled up after mounting the drive motor on the motor axis. The known drive motors for food slicer usually have a motor shaft which has a shoulder on which a separate screw is pressed or shrunk. According to the invention, the preassembled drive motor has a motor axis without a shoulder. After mounting the drive motor, a worm is then rolled directly onto the smooth shaft. This reduces the manufacturing costs. By rolling the worm on a smooth motor axis can be dispensed with in particular the operation of producing a paragraph on the motor axis, since no paragraph on the motor axis is necessary. In the known drive motors, however, a shaft shoulder is necessary to form a seat for the separate screw. In the known drive motors, moreover, the separate screw is machined, which is a relatively expensive production step. Furthermore, the separate screw must be mounted on the motor shaft of the drive motor. In contrast, the rolling of the worm on a smooth motor axis is cheaper and an assembly step can be omitted.

Das freie Ende der Motorachse des Antriebsmotors, das die Schnecke trägt, kann mit seiner Stirnseite an einem an der Lagerplatte angeordneten Axiallager anliegen. Da das Ritzel des Antriebsmotors als Schnecke ausgebildet sein kann, ist sicherzustellen, dass in axialer Richtung der Motorachse auftretende Kräfte axial durch ein Lager abgestützt werden. Dies verhindert ein axiales Ausweichen der Motorachse, wenn der Motor das Antriebszahnrad mittels der Schnecke antreibt. Das Axiallager kann in einer Halterung, die in der Lagerplatte angeformt ist, befestigt sein.The free end of the motor axis of the drive motor, which carries the worm, can rest with its end face on a thrust bearing arranged on the thrust bearing. Since the pinion of the drive motor can be designed as a worm, ensure that forces occurring in the axial direction of the motor axis are axially supported by a bearing. This prevents axial deflection of the motor axis when the motor drives the drive gear by means of the worm. The thrust bearing can be mounted in a holder which is integrally formed in the bearing plate.

Der erfindungsgemäße Allesschneider weist eine Antriebseinheit auf, welche insgesamt einen sehr steifen und kompakten Aufbau aufweist. Durch diesen kompakten steifen Aufbau können sehr enge Fertigungstoleranzen realisiert werden. Die engen Fertigungstoleranzen ermöglichen einen weitgehend spielfreien Antrieb, der sich durch ein äußerst geringes Geräusch auszeichnet und einen schwingungsarmen Betrieb des Allesschneiders ermöglicht. Vorzugsweise kann der erfindungsgemäße Allesschneider deshalb mit einem Gleichstrommotor betrieben werden. Die Verwendung eines Gleichstrommotors ist vorteilhaft, da dieser mit einer geringeren Drehzahl betrieben werden kann, wodurch unerwünschte Schwingungen des Antriebes vermindert werden und aufgrund der geringeren Schwingungen auf eine Gummilagerung der Antriebseinheit am Gehäuse des Allesschneiders verzichtet werden kann. Trotz direkter Befestigung der Antriebseinheit an dem Gehäuse des Allesschneiders arbeitet der Allesschneider sehr geräuscharm.The food slicer according to the invention has a drive unit, which has a very rigid and compact construction overall. Due to this compact rigid construction very tight manufacturing tolerances can be realized. The tight manufacturing tolerances allow a largely backlash-free drive, which is characterized by an extremely low noise and allows low-vibration operation of the food slicer. Preferably, the food slicer invention can therefore be operated with a DC motor. The use of a DC motor is advantageous because it can be operated at a lower speed, which undesirable vibrations of the drive can be reduced and can be dispensed with due to the lower vibrations on a rubber mounting of the drive unit on the housing of the food slicer. Despite direct attachment of the drive unit to the housing of the slicer, the slicer works very quietly.

Eine bevorzugte Ausführungsform der Erfindung ist in den Zeichnungen näher erläutert.A preferred embodiment of the invention is explained in more detail in the drawings.
