Description

Die Erfindung betrifft eine Scheibenschneidmaschine zum Abschneiden von Scheiben aus insbesondere strangförmigem Schneidegut, vorzugsweise Lebensmittel, mit einem Maschinengehäuse, das einen Antriebsmotor und ein vom Antriebsmotor angetriebenes, rotierendes und/oder umlaufend bewegbares Kreismesser haltert, und mit einer Produktzuführung, die das Schneidegut dem Kreismesser zuführt. Die Scheibenschneidemaschine umfasst eine Anschlagplatte sowie einen verschiebbar angeordneten Schlitten, über den das Schneidegut dem Kreismesser zugeführt wird, wobei das Kreismesser direkt an einer im Antriebsmotor für das Kreismesser angeordneten Lagerwelle gelagert ist. Der Antriebsmotor umfasst zumindest einen Stator und einen Rotor.The invention relates to a slicing machine for cutting off slices from, in particular, strand-shaped material to be cut, preferably food, with a machine housing that holds a drive motor and a rotating and / or revolving circular knife driven by the drive motor, and with a product feed that feeds the material to be cut to the circular knife . The slicing machine comprises a stop plate and a displaceably arranged carriage, via which the material to be cut is fed to the circular knife, the circular knife being mounted directly on a bearing shaft arranged in the drive motor for the circular knife. The drive motor comprises at least one stator and one rotor.

Die EP 076 40 73 B1 offenbart eine derartige Schneidemaschine für Nahrungsmittel mit einem Maschinengehäuse und einem Kreismesser. Das Kreismesser ist an einer Lagerwelle gelagert, die durch einen Antriebsmotor mit einem Stator und einem Rotor angetrieben wird. Die Lagerwelle ist ausschließlich im Bereich des Antriebsmotors gelagert.the EP 076 40 73 B1 discloses such a food cutting machine with a machine housing and a circular knife. The circular knife is mounted on a bearing shaft which is driven by a drive motor with a stator and a rotor. The bearing shaft is only supported in the area of the drive motor.

Aus der WO2007/130292A1 ist eine Schneidmaschine bekannt, die einen Motor, eine Lagerwelle, und ein Messer aufweist, das direkt an einem Ende der Lagerwelle angeordnet ist. Ein Kontroller passt die tatsächliche Drehgeschwindigkeit des Messers an die gewünschte Drehgeschwindigkeit an.From the WO2007 / 130292A1 a cutting machine is known which has a motor, a bearing shaft, and a knife which is arranged directly at one end of the bearing shaft. A controller adjusts the actual speed of rotation of the knife to the desired speed of rotation.

Der Antriebsmotor für das Kreismesser lässt sich bei den bekannten Schneidmaschinen nur mit hohem Zeitaufwand in dem jeweiligen Maschinengehäuse der Schneidmaschine positionieren und ausrichten. Außerdem ist es schwierig, den Bereich eines Motorturms der Schneidmaschine, an dem die Motorwelle zur Messerachse hin durch das Gehäuse ragt, gegen Schmutz und Flüssigkeit abzudichten.In the known cutting machines, the drive motor for the circular knife can only be positioned and aligned in the respective machine housing of the cutting machine with great expenditure of time. In addition, it is difficult to seal the area of a motor tower of the cutting machine, where the motor shaft protrudes through the housing towards the knife axis, against dirt and liquid.

Aufgabe der vorliegenden Erfindung ist es demgegenüber, eine Scheibenschneidmaschine der eingangs definierten Art sowie ein Verfahren zur Herstellung der Scheibenschneidmaschine so zu modifizieren, dass der Antriebsmotor sich vergleichsweise einfach und mit geringem Zeitaufwand an dem Maschinengehäuse montieren und ausrichten lässt.In contrast, the object of the present invention is to modify a slicing machine of the type defined at the outset and a method for manufacturing the slicing machine so that the drive motor can be mounted and aligned on the machine housing comparatively easily and with little expenditure of time.

Gelöst wird diese Aufgabe hinsichtlich der Vorrichtung auf technisch besonders einfache und überraschend wirkungsvolle Weise durch eine gattungsgemäße Scheibenschneidmaschine, die sich dadurch auszeichnet, dass der Rotor lösbar von dem Stator ausgebildet ist. Dabei ist der Stator im Maschinengehäuse angeordnet. Das Maschinengehäuse weist eine Einführöffnung auf, an der im montierten Zustand der Stator angeordnet ist und durch die hindurch der Rotor zumindest teilweise in den Stator eingeführt ist. Die Scheibenschneidmaschine weist eine Fixiereinrichtung zur Befestigung von Rotor und Stator mittels Fixiermitteln am Maschinengehäuse auf.With regard to the device, this object is achieved in a technically particularly simple and surprisingly effective manner by a disk cutting machine of the generic type, which is characterized in that the rotor is detachable from the stator. The stator is arranged in the machine housing. The machine housing has an insertion opening at which the stator is arranged in the assembled state and through which the rotor is at least partially inserted into the stator. The disk cutting machine has a fixing device for fastening the rotor and stator to the machine housing by means of fixing means.

Der Stator ist im Inneren des Maschinengehäuses befestigbar. Der Rotor ist anschließend von außen durch die Einführöffnung in das Maschinengehäuse und den Stator einführbar. Der Motor wird nicht als Ganzes montiert. Stator und Rotor werden separat montiert. Dadurch wird eine umständliche und mit hohem Zeitaufwand verbundene Einführung des gesamten Motors in das Maschinengehäuse und eine Ausrichtung des Rotors aus dem Maschinengehäuse heraus vermieden. Insbesondere ist der Stator von innen in einem Motorturm der Scheibenschneidmaschine befestigt und der Rotor von außen am Motorturm befestigt. Der Motorturm lässt sich vergleichsweise schmal ausgestalten. Der vereinfachte Einbau des Motors wird durch den aus dem Stand der Technik nicht bekannten zusätzlichen Schritt der Einführung des Rotors in den Stator nach der Anordnung des Stators (ohne den Rotor und die Lagerwelle) im Maschinengehäuse bewirkt. Im Gegensatz dazu ist im Stand der Technik stets der gesamte Motor innen befestigt und die Motorwelle ragt durch das Gehäuse hindurch. Der Motor muss innerhalb des Motorturms von unten nach oben verschoben werden und die Lagerwelle dann durch eine Öffnung im Maschinengehäuse geführt werden. Das ist nur möglich, wenn der Motorturm sehr breit oder nicht einstückig ausgebildet ist.The stator can be fastened inside the machine housing. The rotor can then be inserted from the outside through the insertion opening into the machine housing and the stator. The engine is not assembled as a whole. The stator and rotor are mounted separately. This avoids the laborious and time-consuming introduction of the entire motor into the machine housing and an alignment of the rotor out of the machine housing. In particular, the stator is fastened from the inside in a motor tower of the disk cutting machine and the rotor is fastened from the outside on the motor tower. The motor tower can be designed to be comparatively narrow. The simplified installation of the motor is brought about by the additional step, not known from the prior art, of introducing the rotor into the stator after the stator has been arranged (without the rotor and the bearing shaft) in the machine housing. In contrast to this, in the prior art, the entire motor is always fastened inside and the motor shaft protrudes through the housing. The motor has to be moved upwards from below within the motor tower and the bearing shaft must then be guided through an opening in the machine housing. This is only possible if the motor tower is very wide or not in one piece.

In einer ersten Ausführungsform der Erfindung umfasst die Fixiereinrichtung erste Durchgangsöffnungen zur Einführung der Fixiermittel, die um die Einführöffnung herum angeordnet sind. Die Durchgangsöffnungen sind insbesondere symmetrisch um die Einführöffnung angeordnet. Durch die ersten Durchgangsöffnungen lassen sich Fixiermittel wie Schrauben oder Bolzen einführen.In a first embodiment of the invention, the fixing device comprises first through openings for introducing the fixing means, which are arranged around the insertion opening. The through openings are in particular arranged symmetrically around the insertion opening. Fixing means such as screws or bolts can be inserted through the first through openings.

Bei einer Weiterbildung dieser Ausführungsform weist der Stator in Umfangsrichtung Fixiermittelaufnahmen zur Aufnahme der Fixiermittel auf. Insbesondere lassen sich die Fixiermittel in den Fixiermittelaufnahmen befestigen.In a further development of this embodiment, the stator has fixation means receptacles for receiving the fixation means in the circumferential direction. In particular, the fixation means can be fastened in the fixation means receptacles.

Bei vorteilhaften Ausführungsformen weist der Rotor in Umfangsrichtung zweite Durchgangsöffnungen zur Einführung der Fixiermittel auf. Die Fixiermittel werden bei dieser Ausführungsform insbesondere durch die zweiten Durchgangsöffnungen hindurchgeführt, um den Rotor an dem Maschinengehäuse zu befestigen.In advantageous embodiments, the rotor has second through openings in the circumferential direction for introducing the fixing means. In this embodiment, the fixing means are in particular passed through the second through openings in order to fasten the rotor to the machine housing.

Eine bevorzugte Ausbildung der Scheibenschneidmaschine ist dadurch gekennzeichnet, dass die Fixiermittelaufnahmen des Stators und die zweiten Durchgangsöffnungen des Rotors an den ersten Durchgangsöffnungen der Fixiereinrichtung zur Einführung der Fixiermittel formschlüssig positionierbar sind. Bei dieser Ausführungsform werden die Fixiermittel insbesondere durch die zweiten Durchgangsöffnungen des Rotors und die ersten Durchgangsöffnungen um die Einführöffnung hindurchgeführt und in die Fixieraufnahmen des Stators eingeführt, in denen sie befestigt werden, zum Beispiel durch Verschrauben in Innengewinden der Fixieraufnahmen. Der Rotor ist dann an dem Maschinengehäuse und dem Stator befestigt. Der Stator ist nicht von innen an das Gehäuse geschraubt. Der Stator wird von innen nur an die richtige Stelle befördert, dann wird der Rotor von außen in den Stator eingeführt und die Fixiermittel, insbesondere Schrauben, die den Rotor an das Maschinengehäuse anschrauben, verschrauben den Stator ebenfalls von außen. Die Fixieraufnahmen des Stators wirken wie Muttern für diese Schrauben.A preferred embodiment of the disk cutting machine is characterized in that the fixation means receptacles of the stator and the second through openings of the rotor can be positively positioned at the first through openings of the fixation device for introducing the fixation means. In this embodiment, the fixing means are passed through the second through-openings of the rotor and the first through-openings around the insertion opening and introduced into the fixing receptacles of the stator, in which they are fastened, for example by screwing into internal threads of the fixing receptacles. The rotor is then attached to the machine housing and the stator. The stator is not screwed to the housing from the inside. The stator is only transported to the right place from the inside, then the rotor is inserted into the stator from the outside and the fixing means, in particular screws that screw the rotor to the machine housing, also screw the stator from the outside. The fixation mounts of the stator act like nuts for these screws.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Scheibenschneidmaschine ist dadurch gekennzeichnet, dass die Lagerwelle im Rotor teilweise oder ganz außerhalb des Maschinengehäuses angeordnet ist. Dies ermöglicht einen vergleichsweise einfachen Austausch der Lagerwelle.A preferred embodiment of the disk cutting machine according to the invention is characterized in that the bearing shaft in the rotor is arranged partially or entirely outside the machine housing. This enables a comparatively simple exchange of the bearing shaft.

Bei einer weiteren Ausführungsform der Scheibenschneidmaschine weist die Einführöffnung des Maschinengehäuses eine stufenförmige Vertiefung oder eine Fase zur zentrierenden Einführung des Rotors auf. Der Stator und der Rotor richten sich durch die Fase beim Befestigen am Maschinengehäuse passend aus.In a further embodiment of the disk cutting machine, the insertion opening of the machine housing has a step-shaped depression or a bevel for the centering insertion of the rotor. The stator and the rotor align themselves appropriately due to the chamfer when they are attached to the machine housing.

Die Scheibenschneidmaschine kann gemäß einer weiteren bevorzugten Ausgestaltung dadurch gekennzeichnet sein, dass an der Innenwand des Maschinengehäuses eine Halterung zum Halten des Stators und/oder des Rotors angeordnet ist. Die Halterung bewirkt insbesondere, dass Stator und Rotor sich automatisch beim Befestigen am Maschinengehäuse ausrichten, sodass bei der Montage alle Komponenten ineinanderpassen. Durch die Halterung wird der Stator stabil gelagert.According to a further preferred embodiment, the slicing machine can be characterized in that a holder for holding the stator and / or the rotor is arranged on the inner wall of the machine housing. In particular, the holder ensures that the stator and rotor align automatically when they are attached to the machine housing, so that all components fit into one another during assembly. The stator is stably supported by the bracket.

Eine vorteilhafte Ausführungsform zeichnet sich dadurch aus, dass am Rotor in Umfangsrichtung sowie anliegend am Maschinengehäuse und am Kreismesser eine Schutzkappe angeordnet ist. Die Schutzkappe dient der Abschirmung des Rotors, insbesondere von Schmutz aus der Umgebung.An advantageous embodiment is characterized in that a protective cap is arranged on the rotor in the circumferential direction and in contact with the machine housing and on the circular knife. The protective cap is used to shield the rotor, in particular from dirt from the environment.

Eine weitere bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass der Rotor einen am Maschinengehäuse und/oder am Stator fixierbaren Fixierteil aufweist, in welchem die Lagerwelle mit dem Kreismesser drehbar, und vorzugsweise gegenüber dem Inneren des Maschinengehäuses fluid-abgedichtet, gelagert ist. Der Rotor lässt sich durch den Fixierteil von außen an dem Maschinengehäuse und/oder dem Stator befestigen.Another preferred embodiment is characterized in that the rotor has a fixing part that can be fixed on the machine housing and / or on the stator, in which the bearing shaft with the circular knife is rotatably mounted and preferably fluid-sealed from the interior of the machine housing.

Die Scheibenschneidmaschine kann gemäß einer weiteren vorteilhaften Ausführungsform dadurch gekennzeichnet sein, dass der Rotor einen Anlageabschnitt aufweist, der einerseits fest auf der Lagerwelle sitzt und durch einen Verbindungsabschnitt mit Kugellagern verbunden ist, welche einen Halterungsabschnitt, der mit dem Stator verbunden ist, von der rotierbaren Lagerwelle trennen, wobei der Verbindungsabschnitt einen schmaleren Durchmesser aufweist als der Anlageabschnitt und der Halterungsabschnitt. Durch Abschnitte mit verschiedenen Durchmessern lässt sich unter anderem das Gewicht des Rotors reduzieren.According to a further advantageous embodiment, the slicing machine can be characterized in that the rotor has a contact section which on the one hand sits firmly on the bearing shaft and is connected by a connecting section to ball bearings which have a mounting section connected to the stator from the rotatable bearing shaft separate, wherein the connecting portion has a narrower diameter than the contact portion and the holding portion. Sections with different diameters can reduce the weight of the rotor, among other things.

Bei einer weiteren bevorzugten Ausführungsform weist der Stator einen Einführring zur Einführung in die Einführöffnung des Maschinengehäuses auf. Bei Verwendung eines solchen Einführrings kann die Einführöffnung mit kleinerem Durchmesser ausgebildet werden als dem Außendurchmesser des Stators.In a further preferred embodiment, the stator has an insertion ring for insertion into the insertion opening of the machine housing. When using such an insertion ring, the insertion opening can be designed with a smaller diameter than the outer diameter of the stator.

Eine bevorzugte Ausführungsform der Scheibenschneidmaschine ist durch einen einstückig ausgebildeten Motorturm gekennzeichnet. Der Antriebsmotor ist vergleichsweise einfach in einem einstückig ausgebildeten Motorturm montierbar. Hierzu wird der Stator in den Motorturm eingeführt und an der Einführungsöffnung positioniert. Der Rotor wird durch die Einführungsöffnung in den Stator eingeführt und an dem Motorturm und dem Stator befestigt. Nach der Montage ist der Stator innen im Motorturm befestigt und der Rotor von außen am Motorturm befestigt.A preferred embodiment of the slicing machine is characterized by a one-piece motor tower. The drive motor is comparatively easy to mount in a one-piece motor tower. For this purpose, the stator is inserted into the motor tower and positioned at the insertion opening. The rotor is inserted into the stator through the insertion opening and attached to the motor tower and the stator. After assembly, the stator is attached to the inside of the motor tower and the rotor is attached to the outside of the motor tower.

In den Rahmen der vorliegenden Erfindung fällt auch ein Verfahren zur Herstellung von erfindungsgemäßen Scheibenschneidmaschinen. Das Verfahren umfasst die folgenden Schritte:

  1. a) Bereitstellung des zweiteiligen Antriebsmotors mit dem Stator und dem vom Stator lösbaren Rotor sowie des Maschinengehäuses mit der Einführöffnung und der Fixiereinrichtung;
  2. b) Vormontage des Stators im Inneren des Maschinengehäuses an der Einführöffnung;
  3. c) Einführung des Rotors von außerhalb des Maschinengehäuses durch die Einführöffnung in den Stator;
  4. d) Befestigung des Rotors und des Stators durch die Fixiereinrichtung am Maschinengehäuse
  5. e) Befestigung des Kreismessers außerhalb des Maschinengehäuses am Rotor.
A method for producing disk cutting machines according to the invention also falls within the scope of the present invention. The procedure consists of the following steps:
  1. a) Provision of the two-part drive motor with the stator and the rotor detachable from the stator and the machine housing with the insertion opening and the fixing device;
  2. b) pre-assembly of the stator inside the machine housing at the insertion opening;
  3. c) introduction of the rotor from outside the machine housing through the introduction opening into the stator;
  4. d) Attachment of the rotor and the stator by the fixing device on the machine housing
  5. e) Attachment of the circular knife outside the machine housing on the rotor.

Bei einem solchen Verfahren lässt sich der Antriebsmotor besonders einfach in dem Maschinengehäuse montieren. Der Stator lässt sich vergleichsweise einfach in das Maschinengehäuse einführen und an der Einführungsöffnung positionieren. Der Rotor kann anschließend durch die Einführungsöffnung teilweise außen an dem Maschinengehäuse und teilweise in dem Rotor angeordnet werden. Ein mit hohem Zeitaufwand verbundenes Positionieren und Ausrichten des Antriebsmotors mit der Antriebswelle in dem Maschinengehäuse wird vermieden.With such a method, the drive motor can be mounted particularly easily in the machine housing. The stator can be inserted comparatively easily into the machine housing and positioned at the insertion opening. The rotor can then be arranged partly on the outside of the machine housing and partly in the rotor through the insertion opening. Positioning and aligning the drive motor with the drive shaft in the machine housing, which is very time-consuming, is avoided.
