Description

Die vorliegende Erfindung betrifft ein Verfahren zur Einstellung des Schneidspaltes an einer Aufschneidevorrichtung zum Schneiden von Lebensmittelprodukten, wobei die Aufschneidevorrichtung ein rotierend angetriebenes Messer, eine Schneidkante und eine Verstellvorrichtung aufweist, die das Messer senkrecht zur Schneidkante auf die Schneidkante zu oder von dieser weg bewegt, bei dem das Messer zunächst durch die Verstellvorrichtung bewegt wird bis eine Berührung des Messers mit der Schneidkante stattfindet und anschließend durch die Verstellvorrichtung ein gewünschter Abstand zwischen Messer und Schneidkante eingestellt wird. Des Weiteren betrifft die vorliegende Erfindung eine Vorrichtung zur Schneidspalteinstellung einer Aufschneidevorrichtung.The present invention relates to a method for adjusting the cutting gap on a slicing device for cutting food products, the slicing device having a rotary driven knife, a cutting edge and an adjustment device which moves the knife perpendicular to the cutting edge towards or away from the cutting edge the knife is first moved by the adjustment until a contact of the knife takes place with the cutting edge and then set by the adjustment a desired distance between the blade and cutting edge. Furthermore, the present invention relates to a device for cutting gap adjustment of a slicing device.

Ein derartiges Verfahren ist aus dem Stand der Technik, beispielsweise der EP 1409210 B1 sowie der WO 2005/009696 bekannt. Das dort beschriebene Verfahren ist jedoch vergleichsweise aufwändig durchzuführen und führt oftmals nicht zu zufriedenstellenden Ergebnissen.Such a method is known in the art, for example EP 1409210 B1 as well as the WO 2005/009696 known. However, the method described there is comparatively complicated to perform and often does not lead to satisfactory results.

Es war deshalb die Aufgabe der vorliegenden Erfindung ein Verfahren und eine Aufschneidevorrichtung zur Verfügung zu stellen, das/die die Nachteile des Standes der Technik nicht aufweist.It was therefore the object of the present invention to provide a method and a slicing apparatus that does not have the disadvantages of the prior art.

Gelöst wird die Aufgabe mit einem Verfahren zur Einstellung des Schneidspaltes an einer Aufschneidevorrichtung zum Schneiden von Lebensmittelprodukten, wobei die Aufschneidevorrichtung ein rotierend angetriebenes Messer, eine Schneidkante und eine Verstellvorrichtung aufweist, die das Messer senkrecht zur Schneidkante auf die Schneidkante zu oder von dieser weg bewegt, bei dem das Messer zunächst durch die Verstellvorrichtung bewegt wird bis eine Berührung des Messers mit der Schneidkante stattfindet und anschließend durch die Verstellvorrichtung ein gewünschter Abstand zwischen Messer und Schneidkante eingestellt wird und bei dem der Schleppfehler

  • des Rotationsantriebs des Messers und/oder
  • des Antriebs der Verstellvorrichtung, die das Messer senkrecht zur Schneidkante bewegt,
bei der Berührung des Messers mit der Schneidkante ermittelt wird.The object is achieved with a method for adjusting the cutting gap on a slicing device for cutting food products, wherein the slicing device has a rotary driven knife, a cutting edge and an adjustment that moves the knife perpendicular to the cutting edge on the cutting edge to or from this, in which the knife is first moved by the adjusting device until a contact of the knife with the cutting edge takes place and then by the adjusting a desired distance between the blade and cutting edge is adjusted and in which the following error
  • the rotary drive of the blade and / or
  • the drive of the adjusting device, which moves the knife perpendicular to the cutting edge,
is determined by the contact of the knife with the cutting edge.

Vorzugsweise ist die Drehrichtung des Messers bei der Fahrt gegen das Messer entgegengesetzt der Drehrichtung im Schneidbetrieb. Dies verhindert eine Beschädigung der Messerschneide bei dem Einstellprozess.Preferably, the direction of rotation of the knife when driving against the knife is opposite to the direction of rotation in the cutting operation. This prevents damage to the knife edge in the adjustment process.

Die Rotation des Messers während des Einstellprozesses hat wesentliche Vorteile gegenüber dem Stand der Technik. Wird das Messer bei Einstellen nicht rotativ bewegt, erfolgt lediglich eine punktuelle Berührung zwischen Messer und Schneidkante an 2 Punkten. Da dieser Berührpunkt je nach relativer Stellung der Messerrotationsachse zur Schneidkante und je nach Ausführung der Schneidkante stark variieren kann, ergibt eine Messung nach dem Stand der Technik eine nur ungenaue Messung. Beim Rotieren des Messers beim Einstellen hingegen wird vorzugsweise die gesamte Überlappungsebene von Messer und Schneidkante jeweils komplett abgefahren.The rotation of the blade during the adjustment process has significant advantages over the prior art. If the knife is not moved rotationally when set, only a point contact between knife and cutting edge takes place at 2 points. Since this contact point can vary greatly depending on the relative position of the blade rotation axis to the cutting edge and depending on the design of the cutting edge, a measurement according to the prior art results in an inaccurate measurement. When rotating the knife during adjustment, however, the entire overlapping plane of the knife and the cutting edge is preferably completely traversed.

Die zu diesem Gegenstand der vorliegenden Erfindung gemachten Ausführungen gelten für die anderen Ausführungen gleichermaßen und umgekehrt.The statements made on this subject of the present invention apply equally to the other embodiments and vice versa.

Die vorliegende Erfindung betrifft ein Verfahren zur Einstellung des Schneidspaltes an einer Aufschneidevorrichtung. Mit einer derartigen Aufschneidevorrichtung werden Lebensmittelriegel, beispielsweise Wurst- Käse oder Schinkenriegel in Lebensmittelscheiben aufgeschnitten. Beim Aufschneiden wirken ein rotierend angetriebenes Schneidmesser und eine Schneidkante schneidend zusammen. Der Schneidspalt ist der Abstand zwischen dem Schneidmesser und einer Schneidkante. Dieser Schneidspalt muss sehr genau eingestellt werden. Ist er zu groß, werden die Produkte zumindest abschnittsweise nicht geschnitten sondern gehackt. Ist er zu klein, kommt es zu einem ständigen, unerwünschten Kontakt zwischen dem Schneidmesser und der Schneidkante, was einen starken Verschleiß des Messers nach sich zieht.The present invention relates to a method for adjusting the cutting gap on a slicing device. With such a slicing device food bars, such as sausage cheese or ham slices are cut into food slices. When cutting a rotating driven cutting blade and a cutting edge act together cutting. The cutting gap is the distance between the cutting blade and a cutting edge. This cutting gap must be set very accurately. If it is too big, the products are at least partially not cut but hacked. If it is too small, there will be a constant, unwanted contact between the cutting blade and the cutting edge, resulting in heavy wear of the blade.

Bei dem erfindungsgemäßen Verfahren ist nun vorgesehen, dass das Messer von einer Verstellvorrichtung senkrecht zur Schneidkante so lange verschoben wird, bis das Messer die Schneidkante berührt. Ausgehend von dieser Berühr-Position als Nullposition kann dann das Schneidmesser von der Verstellvorrichtung um einen definierten Abstand von der Schneidkante wegbewegt werden, der grade so groß ist, dass das Messer nicht gegen die Schneidkante stößt bzw. nicht so groß ist, dass ein Hacken der Produkte resultiert. Dieser Abstand ist der gewünschte Schneidspalt.In the method according to the invention it is now provided that the knife is displaced by an adjusting device perpendicular to the cutting edge until the blade touches the cutting edge. Starting from this contact position as zero position then the cutting blade can be moved away from the adjusting device by a defined distance from the cutting edge, which is just so large that the knife does not hit against the cutting edge or is not so large that a hacking of Products results. This distance is the desired cutting gap.

Gemäß einer ersten erfindungsgemäßen Ausführungsform der vorliegenden Erfindung wird der Schleppfehler des Rotationsantriebs des Messers bei der Berührung der Schneidkante ermittelt. Während dieser Einstellung dreht sich das Schneidmesser oder es pendelt um seine Rotationsachse hin und her. Dabei wird das Messer solange von einer Verstelleinrichtung linear entlang seiner Rotationsachse in Richtung der Schneidkante bewegt, bis es diese berührt. Insbesondere wenn das Messer mit einem vergleichsweise geringen Drehmoment rotierend angetrieben wird, stellt sich bei der Berührung des Messers mit der Schneidkante ein Schleppfehler ein, da das zur Verfügung gestellte Drehmoment nicht groß genug ist, die von einer Regelung geforderte Soll-Position zu halten. Die Ist-Position des Messers wird folglich der Soll-Position hinterher hinken. Diese Differenz wird als Schleppfehler bezeichnet. Sobald folglich ein solcher Schleppfehler eintritt, weiß die Maschinensteuerung, dass das Messer die Schneidkante berührt hat und die lineare Verstellung des Messers in Richtung der Schneidkante wird gestoppt. Ausgehend von dieser Berühr-Position als Nullposition kann dann das Schneidmesser um einen definierten Abstand von der Schneidkante wegbewegt werden, der grade so groß ist, dass das Messer nicht gegen die Schneidkante stößt bzw. nicht so groß ist, dass ein Hacken der Produkte resultiert. Dieser Abstand ist der gewünschte Schneidspalt.According to a first embodiment of the present invention, the following error of the rotary drive of the knife is determined upon contact of the cutting edge. During this adjustment, the cutting blade rotates or oscillates about its axis of rotation back and forth. The knife is as long as one Adjustment linear moves along its axis of rotation in the direction of the cutting edge until it touches them. In particular, when the blade is driven to rotate with a comparatively small torque, a tracking error arises when the blade touches the cutting edge, since the torque provided is not large enough to maintain the desired position required by a control. The actual position of the knife will consequently lag behind the nominal position. This difference is referred to as a following error. Consequently, as soon as such a following error occurs, the machine control knows that the knife has touched the cutting edge and the linear displacement of the knife in the direction of the cutting edge is stopped. Starting from this contact position as a zero position, the cutting blade can then be moved away from the cutting edge by a defined distance, which is just so great that the blade does not hit against the cutting edge or is not so large that chipping of the products results. This distance is the desired cutting gap.

Bei einer zusätzlichen oder alternativen Ausführungsform der vorliegenden Erfindung wird der Schleppfehler des Antriebs der Verstellvorrichtung ermittelt, die das Schneidmesser senkrecht zur Schneidebne linear verschiebt, ermittelt. Sobald das Messer die Schneidkante berührt, tritt ein Schleppfehler beim Antrieb der Verstellvorrichtung ein, da die von einer Regelung geforderte Soll-Position von dem Antrieb nicht gehalten werden kann. Die Ist-Position des Messers wird folglich der Soll-Position hinterher hinken. Diese Differenz wird als Schleppfehler bezeichnet. Sobald folglich ein solcher Schleppfehler eintritt, weiß die Maschinensteuerung, dass das Messer die Schneidkante berührt hat. Der Anrieb wird dann vorzugsweise sofort abgestellt. Ausgehend von dieser Berühr-Position als Nullposition kann dann das Schneidmesser um einen definierten Abstand von der Schneidkante wegbewegt werden, der grade so groß ist, dass das Messer nicht gegen die Schneidkante stößt bzw. nicht so groß ist, dass ein Hacken der Produkte resultiert. Dieser Abstand ist der gewünschte Schneidspalt. Vorzugsweise pendelt das Messer bei der Verschiebung des Messers hin und her.In an additional or alternative embodiment of the present invention, the following error of the drive of the adjusting device is determined, which moves the cutting blade perpendicular to the Schneidebne linear determined. As soon as the knife touches the cutting edge, a following error occurs when the adjusting device is driven, since the desired position required by a control can not be held by the drive. The actual position of the knife will consequently lag behind the nominal position. This difference is referred to as a following error. Consequently, as soon as such a following error occurs, the machine control knows that the knife has touched the cutting edge. The anhydride is then preferably turned off immediately. Starting from this contact position as a zero position, the cutting blade can then be moved away from the cutting edge by a defined distance, which is just so great that the blade does not hit against the cutting edge or is not so large that chipping of the products results. This distance is the desired cutting gap. Preferably, the knife oscillates during the displacement of the knife back and forth.

Die zu diesem Gegenstand der vorliegenden Erfindung gemachten Ausführungen gelten für die anderen Gegenstände der vorliegenden Erfindung gleichermaßen und umgekehrt.The statements made on this subject of the present invention apply equally to the other objects of the present invention and vice versa.

Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung pendelt oder rotiert das Schneidmesser bei der Einstellung des Einstellung des Schneidspaltes, insbesondere bei der Ermittlung der Berührposition als Nullposition um seine Rotationsachse. Pendeln im Sinne der Erfindung bedeutet, dass das Schneidmesser bei dem Einstellvorgang vor- und zurückrotiert, besonders bevorzugt keine vollständige Drehbewegung vollführt.According to a preferred embodiment of the present invention, the cutting blade oscillates or rotates when setting the setting of the cutting gap, in particular when determining the contact position as a zero position about its axis of rotation. Commuting within the meaning of the invention means that the cutting blade rotates back and forth in the adjustment process, particularly preferably does not perform a complete rotational movement.

Erfindungsgemäß ist bei dieser Ausführungsform nun vorgesehen, dass die Veränderung eines Parameters des Pendel-/Rotationsantriebs bei der Berührung des Messers mit der Schneidkante gemessen wird. Vorzugsweise handelt es sich bei diesem Parameter um einen Schleppfehler des Pendel-/Rotationsantriebs. Ausgehend von dieser Berühr-Position als Nullposition kann dann das Schneidmesser um einen definierten Abstand von der Schneidkante wegbewegt werden, der grade so groß ist, dass das Messer nicht gegen die Schneidkante stößt bzw. nicht so groß ist, dass ein Hacken der Produkte resultiert. Dieser Abstand ist der gewünschte Schneidspalt.According to the invention, it is now provided in this embodiment that the change in a parameter of the pendulum / rotary drive is measured when the blade touches the cutting edge. Preferably, this parameter is a following error of the pendulum / rotary drive. Starting from this contact position as a zero position, the cutting blade can then be moved away from the cutting edge by a defined distance, which is just so great that the blade does not hit against the cutting edge or is not so large that chipping of the products results. This distance is the desired cutting gap.

Vorzugsweise vollführt das Schneidmesseresser bei der Einstellung des Schneidspaltes zumindest zeitweise eine Schraubenbewegung; d.h. es rotier/pendelt und wird gleichzeitig axial verschoben bis es die Schneidkante berührt und/oder bis der gewünschte Schneidspalt eingestellt ist.Preferably, the cutting blade knife performs at least temporarily a screw movement when setting the cutting gap; i.e. it rotates / oscillates and is simultaneously moved axially until it touches the cutting edge and / or until the desired cutting gap is set.

Die Produktauflage 3 ist hierbei zum Beispiel eine Rollenbahn und/oder ein Förderband und gestattet ein möglichst leichtgängiges Transportieren des Lebensmittels 2 in Richtung eines Schneidmessers 4The slicing device 1 according to the invention is arranged on a base 10 by means of the frame 11. A food bar 2, for example a sausage, meat or cheese seal, rests on the product support 3. The product support 3 is in this case, for example, a roller conveyor and / or a conveyor belt and permits the smoothest possible transporting of the food 2 in the direction of a cutting knife 4

Das Lebensmittel 2 wird hierbei von einer Fördervorrichtung 30 in Richtung des Schneidmessers 4 gefördert. Bei dem Schneidmesser kann es sich beispielsweise um ein Kreis- oder ein Sichelmesser handeln. Die Fördervorrichtung 30 ist hier beispielhaft durch einen Spindelantrieb 32 ausgebildet, auf welchem ein Greifer 34 schlittenartig geführt ist, der in klammerartigem Eingriff mit dem hinteren Ende des Lebensmittelriegels steht. Durch die Rotation der Spindel 32 bewegt sich der Greifer 34. Durch den Greifer 34 wird die Förderbewegung, des Spindelantriebs 32 auf das Lebensmittel 2 übertragen. Für die Ausgestaltung der Fördervorrichtung 3 sind aber auch viele andere Ausgestaltungen bekannt und einsetzbar. Die Förderung des Lebensmittelriegels kann aber auch allein oder zusätzlich durch Transportbänder erfolgen, die sich unterhalb und/oder oberhalb des Lebensmittelriegels 2 befinden.The food 2 is thereby conveyed by a conveyor 30 in the direction of the cutting blade 4. The cutting blade may be, for example, a circular or a sickle blade. The conveyor device 30 is here exemplified by a spindle drive 32 on which a gripper 34 is guided in a slide-like, which is in a clamp-like engagement with the rear end of the food bar. By the rotation of the spindle 32, the gripper 34 moves. By the gripper 34, the conveying movement, the spindle drive 32 is transmitted to the food 2. For the design of the conveyor device 3 but also many other configurations are known and can be used. The promotion of the food bar can also be done alone or in addition by conveyor belts that are located below and / or above the food bar 2.

Das Schneidmesser 4 befindet sich in der Regel in einem Schneidmessergehäuse 40. Das Schneidmesser 4 besitzt einen hier nicht weiter dargestellten Schneidmesserantrieb, der das Schneidmesser 4 in Rotation 41 versetzt. Das Schneidmesser 4 ist zum Beispiel auf einem Planetengetriebe angeordnet und führt so neben der Rotation um seine Drehachse auch eine Rotation der Drehachse um die Achse des Planetengetriebes aus. Hieraus resultiert, dass das Schneidmesser 4 periodisch umläuft und zum Beispiel von oben an das Lebensmittel 2 heranfahrend in dieses eindringt und eine Lebensmittelscheibe (nicht dargestellt) abtrennt, die dann nach unten auf ein ebenfalls nicht dargestelltes Förderband fallen lässt. Durch die planetenartige Umlaufbewegung des Schneidmessers 4 wird das vordere Ende 20 des Lebensmittels 2 regelmäßig wieder freigegeben und die Fördervorrichtung 30 fördert in diesem Zeitsegment das Lebensmittel 2 gerade um die Scheibendicke nach vorne. Das Freigeben des vorderen Endes 20 des Lebensmittels 2 kann aber auch dadurch erreicht werden, dass es sich um ein Sichelmesser handelt. In diesem Fall kann auf die Planetenbewegung des Schneidkopfes verzichtet werden. Beim Schneiden wirkt das Schneidmesser 4 mit einer Schneidkante 42, die sich hier am vorderen Ende der Produktauflage 3 befindet. Erfindungsgemäß wird vorgeschlagen, dass eine Verstellvorrichtung angeordnet ist, die bewirkt, dass der Abstand zwischen dem Schneidmesser 4 und dem vorderen Ende 20 des Lebensmittels 2 und/oder der Schneidkante 42 veränderbar ist. Diese Verschiebung des Schneidmessers entlang seiner Rotationsachse und relativ zu der Schneidkante 42 wird in dem vorliegenden Fall zur Einstellung des Schneidspaltes herangezogen, indem das Schneidmesser beabstandet von der Schneidkante so lange auf diese zu bewegt wird, bis das Messer die Schneidkante berührt. Bei dieser Berührung wird dann beispielsweise die Veränderungen der Rotation des Schneidmessers, beispielsweise in Form eines Schleppfehlers, gemessen, um die Berührung des Schneidmessers mit der Schneidkante festzustellen. Gemäß einer bevorzugten Ausführung vollführt das Schneidmesser bei der Messung keine vollständigen Umdrehungen, sondern pendelt, von dem Rotationsantrieb angetrieben hin und her. Alternativ dreht sich das Messer um seine Rotationsachse. Beispielsweise wird bei dem Rotationsantrieb oder Pendelantrieb das Auftreten eines Schleppmomentes ermittelt und/oder es wird eine veränderte Stromaufnahme oder eine veränderte Spannung in dem Rotationsantrieb gemessen. Beim "Schleppmoment" wird das Messer, vorzugsweise mit einem geringen Drehmoment, rotativ angetrieben und ständig die Ist-Position des Rotationsantriebs mit einer Soll-Position verglichen. Weicht die Ist-Position von der Soll-Position ab (= Schleppfehler) geht man davon aus, dass das Messer die Schneidleiste berührt hat und die Nullstellung erreicht ist. Sobald die Berührung des Messers mit der Schneidkante festgestellt wurde, wird seine Verstellung in Richtung der Schneidkante vorzugsweise gestoppt oder zumindest vermindert und das Schneidmesser kann, ausgehend von dieser "Null-Position", von der Verstellvorrichtung wieder um ein definiertes Maß von der Schneidkante wegbewegt werden. Dieser Abstand ist dann der gewünschte Schneidspalt. Alternativ oder zusätzlich wird der Schleppfehler des Antriebs der Verstellvorrichtung, die das Schneidmesser in Richtung der Schneidkante und davon weg bewegt, gemessen. Dabei wird das Messer von der Verstellvorrichtung mit einem sehr geringen Strom und einer geringen Geschwindigkeit axial entlang seiner Rotationsachse in Richtung die Schneidkante gefahren. Dabei wird ständig die Ist-Position des Verstellantriebs mit der Soll-Position verglichen. Weicht die Ist-Position von der Soll-Position ab (= Schleppfehler) geht man davon aus, dass das Messer die Schneidleiste berührt hat und die Nullstellung erreicht ist. Ausgehend von dieser Nullstellung kann dann der gewünschte Schneidspalt eingestellt werden.The cutting blade 4 is usually located in a cutting blade housing 40. The cutting blade 4 has a cutting blade drive not shown here, which puts the cutting blade 4 in rotation 41. The cutting blade 4 is arranged, for example, on a planetary gear and thus performs in addition to the rotation about its axis of rotation and a rotation of the axis of rotation about the axis of the planetary gear. This results in that the cutting blade 4 rotates periodically and, for example, from the top of the food 2 approaching penetrates into this and a food slice (not shown) separates, which can then fall down on a likewise not shown conveyor belt. Due to the planetary orbital movement of the cutting blade 4, the front end 20 of the food 2 is released regularly and the conveyor 30 promotes food in this time segment 2 straight to the pane thickness forward. The release of the front end 20 of the food 2 can also be achieved in that it is a sickle knife. In this case, can be dispensed with the planetary movement of the cutting head. When cutting the cutting blade 4 acts with a cutting edge 42, which is here at the front end of the product support 3. According to the invention it is proposed that an adjusting device is arranged, which causes the distance between the cutting blade 4 and the front end 20 of the food 2 and / or the cutting edge 42 is variable. This displacement of the cutting blade along its The axis of rotation and relative to the cutting edge 42 is used in the present case for adjusting the cutting gap by the cutting blade spaced from the cutting edge as long moved to this until the blade touches the cutting edge. In this contact, then, for example, the changes in the rotation of the cutting blade, for example in the form of a drag error, measured to determine the contact of the cutting blade with the cutting edge. According to a preferred embodiment, the cutting blade does not perform complete revolutions in the measurement, but oscillates, driven by the rotational drive back and forth. Alternatively, the knife rotates about its axis of rotation. For example, in the rotary drive or pendulum drive, the occurrence of a drag torque is determined and / or an altered power consumption or a changed voltage in the rotary drive is measured. When "drag torque", the knife, preferably with a low torque, rotatively driven and constantly compared the actual position of the rotary drive with a desired position. If the actual position deviates from the setpoint position (= following error), it is assumed that the knife has touched the cutter bar and the zero setting has been reached. Once contact of the knife with the cutting edge has been detected, its displacement towards the cutting edge is preferably stopped or at least reduced and the cutting knife, starting from this "zero position", can again be moved away from the cutting edge by a defined amount by the adjustment device , This distance is then the desired cutting gap. Alternatively or additionally, the following error of the drive of the adjusting device, which moves the cutting blade in the direction of the cutting edge and away from it, measured. The knife is driven by the adjusting device with a very low current and a low speed axially along its axis of rotation in the direction of the cutting edge. In this case, the actual position of the adjusting drive is constantly compared with the desired position. If the actual position deviates from the setpoint position (= following error), it is assumed that the knife has touched the cutter bar and the zero setting has been reached. Starting from this zero position then the desired cutting gap can be adjusted.
