Description

Die Erfindung betrifft ein Verfahren zum Steuern einer Schneidemaschine, sowie eine Schneidemaschine für Lebensmittel. Ein Verfahren und eine Vorrichtung gemäß des Oberbegriffs der Ansprüche 1 und 7 sind etwa aus der EP 0 574 649 A1 bekannt.The invention relates to a method for controlling a cutting machine, as well as a cutting machine for food. A method and an apparatus according to the preamble of claims 1 and 7 are approximately from the EP 0 574 649 A1 known.

Aus der DE 1 961 069 A ist eine Schneidemaschine für Lebensmittel bekannt, die mit einem rotierenden Schneidmesser von einem strangförmigen Schneidgut Scheiben abtrennt. Über einen Kettenrahmen und einen Abschläger werden die abgetrennten Scheiben automatisch auf einer Ablagefläche abgelegt. Der Abschläger wird dabei über einen Hubmagneten angetrieben, der dem Abschläger einen konstanten Bewegungsablauf vorgibt.From the DE 1 961 069 A is a cutting machine for food is known, which separates with a rotating blade from a strand-like cutting slices. About a chain frame and a decoy the separated slices are automatically stored on a shelf. The Abschläger is driven by a solenoid, which dictates the Abschläger a constant movement.

Die DE 29 42 418 C2 zeigt ebenfalls eine Schneidemaschine für Lebensmittel mit einem angetriebenen Abschläger. Als Antrieb wird ein mehrpoliger Elektromagnet verwendet, um das Reversieren des Abschlägers besser steuern zu können.The DE 29 42 418 C2 also shows a food slicer with a powered slicer. The drive is a multi-pole electromagnet used to better control the reversing of the blower.

In der Praxis stellt sich oft das Problem, mit dem Schnittgut ein exaktes Ablagebild zu schaffen. Es hat sich gezeigt, dass unterschiedliche Lebensmittelscheiben sich jeweils individuell verhalten, indem sie z. B. unterschiedlich stark an dem Kettenrahmen haften oder nach dem Verlassen des Abschlägers auf der Bahn bis hin zu der Ablagefläche eine eigene Flugcharakteristik aufweisen.In practice, the problem often arises of creating a precise storage image with the clippings. It has been shown that different food slices each behave individually by z. B. different degrees of adhesion to the chain frame or have after leaving the Abschlägers on the web up to the storage area own flight characteristics.

Der Erfindung liegt die Aufgabe zugrunde eine Steuerung einer Schneidemaschine zu entwickeln, die es ermöglicht, auch bei unterschiedlichem Schneidgut ein möglichst gutes Ablagebild zu erzielen.The invention has for its object to develop a control of a cutting machine, which makes it possible to achieve the best possible storage image even with different cutting material.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren nach den Merkmalen des Anspruchs 1 und eine Schneidemaschine nach den Merkmalen des Anspruchs 7 gelöst.This object is achieved by a method according to the features of claim 1 and a cutting machine according to the features of claim 7.

Die Schneidemaschine weist einen mit einer Steuerungsvorrichtung verbundenen Abschläger auf. Diese steuert den Abschläger anhand unterschiedlicher Antriebsprofile, wobei ein Antriebsprofil anhand eines vorgegebenen Parameters bestimmt wird. Als Parameter kann z. B. die Scheibendicke oder der Scheibendurchmesser der abgetrennten Lebensmittelscheiben dienen. Die abgetrennten Scheiben haften auf dem Transportkettenrahmen abhängig von ihrer Scheibendicke oder ihrem Durchmesser unterschiedlich stark. Vorzugsweise werden die Lebensmittelscheiben auf Dornen der Transportketten des Kettenrahmens aufgespießt und müssen dort von einem Abschläger herausgelöst werden. Diese Kraft ist abhängig von der Scheibendicke bzw. dem Scheibendurchmesser. Es besteht auch die Gefahr, dass sehr dünne Scheiben durch eine falsch bemessene Auslösekraft beschädigt werden. Ein passendes Antriebsprofil variiert nun die Auslösekraft der Scheiben, indem das Anfangsmoment des Abschlägers abhängig von dem Parameter variabel gesteuert wird. Darüber hinaus ist als weiterer Parameter die Art des zu schneidenden Lebensmittels, wie z. B. Käse, Wurst, Fleisch, Fisch oder Gemüse vorgesehen. Jedes dieser Lebensmittel besitzt eine individuelle Haftung bzw.The cutting machine has a beater connected to a control device. This controls the decoy on the basis of different drive profiles, wherein a drive profile is determined based on a predetermined parameter. As a parameter z. B. serve the thickness of the disc or the diameter of the separated food slices. The separated slices adhere to different degrees on the transport chain frame depending on their slice thickness or their diameter. Preferably, the food slices are skewered on thorns of the transport chains of the chain frame and must be removed there from a slapper. This force depends on the thickness of the disc or the diameter of the disc. There is also the danger that very thin disks will be damaged by a wrongly sized release force. A matching drive profile now varies the release force of the discs by variably controlling the initial torque of the decanter, depending on the parameter. In addition, the type of food to be cut, such as. Cheese, sausage, meat, fish or vegetables. Each of these foods has an individual liability or

Ablösekraft vom Transportkettenrahmen, die mit einem entsprechenden Antriebsprofil berücksichtigt wird.Removal force from the transport chain frame, which is taken into account with a corresponding drive profile.

Außer der Auslösekraft kann das Antriebsprofil noch weitere Variationen des Antriebs vornehmen. So ist beispielsweise vorgesehen, dass der Weg, insbesondere der Schwenkwinkel oder die Geschwindigkeit abhängig von einer gewünschten Ablageposition der Lebensmittelscheiben variiert wird. In der Praxis ist es oftmals wünschenswert aus mehreren Scheiben des Schnittguts zweidimensionale Figuren wie z. B. Kreise oder Vierecke zu legen. Dabei ist eine exakte Positionierung jeder einzelnen Scheibe wichtig. Über die variable Steuerung des Schwenkwinkels und/oder der Geschwindigkeit und/oder des Umkehrpunkts des Abschlägers kann eine verbesserte Genauigkeit bei der Positionierung der Scheiben erzielt werden.In addition to the release force, the drive profile can make further variations of the drive. For example, it is provided that the path, in particular the swivel angle or the speed is varied depending on a desired storage position of the food slices. In practice, it is often desirable from several slices of the crop two-dimensional figures such. B. circles or squares to lay. An exact positioning of each individual disc is important. By the variable control of the swivel angle and / or the speed and / or the reversal point of the whipper, an improved accuracy in the positioning of the slices can be achieved.

In einer Ausführung ist vorgesehen, dass eine Datenbank vorgesehen ist, die eine Anzahl an unterschiedlichen Antriebsprofilen aufweist. Anhand der vorgegebenen Parameter bestimmt die Steuerungsvorrichtung das für die jeweilige Aufgabe am besten geeignete Antriebsprofil über eine Selektion und steuert den Abschläger anhand dieses selektierten Antriebsprofils. Die Auswahl der Antriebsprofile kann die Steuerungsvorrichtung anhand fester Zuordnungen zwischen Parametern und Antriebsprofilen, vorzugsweise Verweistabellen, oder anhand eines Algorithmus vornehmen.In one embodiment, it is provided that a database is provided which has a number of different drive profiles. On the basis of the predetermined parameters, the control device determines the drive profile most suitable for the respective task via a selection and controls the stripper on the basis of this selected drive profile. The selection of the drive profiles, the control device based on fixed assignments between parameters and drive profiles, preferably look-up tables, or make an algorithm.

In einer Ausführung kann vorgesehen sein, dass die Steuerungsvorrichtung einen Optimierungsalgorithmus aufweist und das Antriebsprofil anhand der vorgegebenen Parameter bestimmt, indem ein individuelles Antriebsprofil mit diesem Optimierungsalgorithmus berechnet wird oder indem ein vorhandenes Antriebsprofil mit dem Optimierungsalgorithmus angepasst wird.In an embodiment it can be provided that the control device has an optimization algorithm and the drive profile is determined on the basis of the predetermined parameters by calculating an individual drive profile with this optimization algorithm or by adapting an existing drive profile with the optimization algorithm.

Die Vorgabe der Parameter kann besonders komfortabel bereits durch die für einen Schneidebetrieb zwingend notwendigen Einstellungen der Schneidemaschine, wie z. B. der Scheibendicke oder durch Übermitteln der Werte aus einem weiteren zentralen Steuergerät automatisch erfolgen. In dem Fall ist ein zusätzlicher Bedienungsschritt zur manuellen Eingabe der Parameter nicht notwendig. Es ist jedoch auch vorgesehen, dass die Schneidemaschine eine mit der Steuerungsvorrichtung verbundene Eingabevorrichtung, vorzugsweise Tastatur oder Touch-Screen, zur manuellen Eingabe von Parametern aufweist.The specification of the parameters can be particularly comfortable already by the mandatory for a cutting operation settings of the cutting machine, such. B. the thickness or by transmitting the values from another central control unit automatically. In that case, an additional operation step for manually entering the parameters is not necessary. However, it is also envisaged that the cutting machine has an input device connected to the control device, preferably a keyboard or a touch screen, for the manual input of parameters.

In einer Ausführung ist vorgesehen, dass die Steuerungsvorrichtung den Antriebsmotor des Abschlägers steuert, um das entsprechende Antriebsprofil zu erzielen. Der Antriebsmotor kann als elektrischer Synchronmotor oder Schrittmotor ausgeführt sein. Die Steuerung kann erfolgen, indem der Speisestrom des Antriebsmotors, insbesondere die Polarität, und/oder die Frequenz und/oder die Stromaufnahme gezielt variiert wird. So kann zu jedem Zeitpunkt ein bestimmtes Antriebsmoment, und/oder ein bestimmter Umkehrpunkt und/oder eine bestimmte Geschwindigkeit des Abschlägers eingestellt werden. Ein besonders gutes Ergebnis lässt sich erzielen, indem ein Sensor vorgesehen ist, der der Steuerungsvorrichtung eine Rückmeldung über den Weg bzw. die Geschwindigkeit des Abschlägers gibt. Insbesondere kann ein Wegsensor mit dem Antriebsmotor oder dem Abschläger verbunden sein. Alternativ oder zusätzlich kann anhand der Parameter des Antriebsmotors, insbesondere der Stromaufnahme das notwendige Drehmoment und damit das Gewicht der zu transportierenden Lebensmittelscheiben ermittelt werden. Durch Auswertung der Sensorsignale und/oder der Parameter des Antriebsmotors in der Steuerungsvorrichtung kann eine exakte Regelung des Abschlägers erzielt werden.In one embodiment, it is provided that the control device controls the drive motor of the Abschlägers to achieve the corresponding drive profile. The drive motor can be designed as a synchronous electric motor or stepper motor. The control can be effected by selectively varying the supply current of the drive motor, in particular the polarity, and / or the frequency and / or the current consumption. Thus, a specific drive torque, and / or a specific reversal point and / or a specific speed of the decanter can be set at any time. A particularly good result can be achieved by providing a sensor which provides the control device with feedback about the path or the speed of the blower gives. In particular, a displacement sensor can be connected to the drive motor or the striker. Alternatively or additionally, the necessary torque and thus the weight of the food slices to be transported can be determined on the basis of the parameters of the drive motor, in particular the power consumption. By evaluating the sensor signals and / or the parameters of the drive motor in the control device, an exact control of the Abschlägers can be achieved.

  • FIG. 3 : A variant of the drive of the blower.

In der Figur 1 ist schematisch der Aufbau einer Schneidemaschine 1 dargestellt. Beispielhaft ist ein sogenannter Vertikalschneider gezeigt. Das bedeutet, die Schneidemaschine 1 weist ein angetriebenes Schneidmesser 11 auf, welches in einer vertikalen Schneidebene B rotiert.In the FIG. 1 schematically the structure of a cutting machine 1 is shown. By way of example, a so-called vertical cutter is shown. That is, the cutting machine 1 has a driven cutting blade 11 which rotates in a vertical cutting plane B.

Über eine verstellbare Anschlagplatte, die parallel zum Schneidmesser 11 angeordnet ist, wird ein Schneidspalt eingestellt. Die Breite des Schneidspaltes bestimmt die Dicke der von einem Lebensmittelstrang 14 abgeschnittenen Scheiben. Die abgeschnittenen Scheiben werden von einer Transportvorrichtung aufgenommen und über einen Transportkettenrahmen 3 und eine Ablagevorrichtung 4 auf einen Ablagetisch 43 abgelegt. Von dort können die abgetrennten Scheiben entnommen werden.Via an adjustable stop plate, which is arranged parallel to the cutting blade 11, a cutting gap is set. The width of the cutting gap determines the thickness of the sliced from a food strand 14 slices. The cut-off wheels are picked up by a transport device and deposited on a storage table 43 via a transport chain frame 3 and a storage device 4. From there, the separated slices can be removed.

Der Lebensmittelstrang 14 wird zum Schneiden auf einen Schlitten 12 aufgelegt und von diesem geführt. Der Schlitten 12 ist senkrecht zu dem Schneidmesser 11 bzw. der Schneidebene B angeordnet und parallel zu der Schneidebene B verschiebbar in einem Maschinengehäuse 15 gelagert. Das Maschinengehäuse 15 nimmt die Antriebsmotoren und Steuergeräte der Schneidemaschine 1 auf. Der Schlitten 12 wird zum Schneiden entweder manuell oder motorisch angetrieben, wobei je Schnitt ein Hub ausgeführt wird. An seiner Vorderseite, d. h. an der einem Bediener zugewandten Seite, weist der Schlitten 12 eine Handschutzplatte auf, die den Schlitten 12 nach vorne abdeckt. Die Handschutzplatte verhindert, dass ein Bediener unbeabsichtigt mit seiner Hand in den Schneidebereich des Messers 11 gelangt.The food strand 14 is placed on a carriage 12 for cutting and guided by this. The carriage 12 is arranged perpendicular to the cutting blade 11 or the cutting plane B and mounted parallel to the cutting plane B displaceable in a machine housing 15. The machine housing 15 accommodates the drive motors and control devices of the cutting machine 1. The carriage 12 is driven for cutting either manually or by motor, wherein each cut a stroke is performed. At its front, d. H. on the side facing an operator, the carriage 12 has a hand guard plate which covers the carriage 12 to the front. The handguard prevents an operator from inadvertently getting his hand into the cutting area of the knife 11.

Beim Schneiden ist es notwendig, dass der Lebensmittelstrang 14 der Schneidebene B bzw. dem Schneidmesser 11 kontinuierlich zugestellt wird. Dafür weist der Schlitten 12 eine Zustelleinrichtung 13 auf, die das Schneidgut 14 zustellt.When cutting, it is necessary that the food strand 14 of the cutting plane B and the cutting blade 11 is continuously delivered. For this purpose, the carriage 12 has an infeed device 13 which delivers the material 14 to be cut.

Die abgetrennten Scheiben des Lebensmittelstrangs werden hinter dem Schneidmesser 11 von dem Transportkettenrahmen 3 aufgenommen, der zum Transport von abgetrennten Scheiben mehrere parallel umlaufende Ketten 31 aufweist. Die Ketten 31 weisen zum Halten der Scheiben Kettenglieder mit Drahtspitzen auf, auf die Lebensmittelscheiben aufgespießt werden. Das Ablegen der Scheiben erfolgt mittels einer Ablagevorrichtung 4, die in den Figuren 2 und 3 vergrößert dargestellt ist. Die Ablegevorrichtung 4 umfasst einen Abschläger 41, der um eine horizontal verlaufende Drehachse A schwenkbar gelagert ist. Der Abschläger 41 weist mehrere beabstandete Finger 42 auf, die zwischen die umlaufenden Ketten 31 des Transportkettenrahmens 3 eingreifen und die Scheiben auf einer Ablagefläche 43 ablegen. Zum Ablegen der Scheiben schwenkt der Abschläger 41 um eine horizontale Drehachse A. Dabei löst er die auf den Kettenspitzen festsitzenden Scheiben und nimmt diese in seiner Schwenkbewegung mitThe separated slices of food strand are received behind the cutting blade 11 of the transport chain frame 3, which has a plurality of parallel circumferential chains 31 for the transport of separated slices. The chains 31 have to hold the discs on chain links with wire tips, are impaled on the food slices. The discarding takes place by means of a storage device 4, which in the Figures 2 and 3 is shown enlarged. The laying device 4 comprises a knocker 41, which is mounted pivotably about a horizontally extending axis of rotation A. The stripper 41 has a plurality of spaced fingers 42 which engage between the circulating chains 31 of the transport chain frame 3 and deposit the discs on a shelf 43. To deposit the discs, the striker 41 pivots about a horizontal axis of rotation A. In doing so, it releases the discs which are stuck on the chain tips and carries them along in its pivoting movement

In den Figuren 2 und 3 ist der Bewegungsablauf des Abschlägers 41 beim Ablegen der Scheiben auf die Ablagefläche 43 dargestellt. Der Bewegungsablauf des Abschlägers 41 ist variabel und wird von einer Steuerungsvorrichtung 6 entsprechend einem bestimmten Antriebsprofil gesteuert. Dabei kann das Moment, und/oder die Geschwindigkeit, und/oder der Wegverlauf, und/oder der Umkehrpunkt des Abschlägers 41 anhand variabel gestaltet werden.In the Figures 2 and 3 the sequence of movement of the Abschlägers 41 when placing the discs on the shelf 43 is shown. The movement sequence of the whipper 41 is variable and is controlled by a control device 6 in accordance with a specific drive profile. In this case, the moment, and / or the speed, and / or the route, and / or the turning point of the punch 41 can be made variable based.

Der Abschläger 41 ist um eine horizontale Achse A schwenkbar gelagert. Eine Abtriebswelle 51 eines elektrischen Antriebsmotors 5 ist mit dem unteren Abschnitt des Abschlägers 41 verbunden. Die in Figur 2 dargestellte Variante zeigt eine Lösung, die der die Abtriebswelle 51 des Motors 5 die Schwenkachse A des Abschlägers bildet. Bei der in Figur 3 dargestellten Variante ist der Abschläger 41 über ein Getriebe mit einem Zahnriemen 52 mit der Abtriebswelle 51 verbunden.The beater 41 is pivotally mounted about a horizontal axis A. An output shaft 51 of an electric Drive motor 5 is connected to the lower portion of the striker 41. In the FIG. 2 illustrated variant shows a solution that forms the output shaft 51 of the motor 5, the pivot axis A of the Abschlägers. At the in FIG. 3 illustrated variant of the Abschläger 41 is connected via a gear with a toothed belt 52 to the output shaft 51.

Ein Steuergerät 6 ist in dem Maschinengehäuse 15 angeordnet und regelt den elektrischen Antriebsmotor 5 über eine Verbindungsleitung. Dazu weist der elektrische Antriebsmotor 5 einen Sensor auf, der die Position bzw. den Weg des Abschlägers 41 misst und an das Steuergerät 6 übermittelt. Das Steuergerät 6 kann so anhand eines gewünschten Antriebsprofils das notwendige Antriebsmoment oder die erforderliche Geschwindigkeit bestimmen und den Antriebsmotor 5 exakt ansteuern.A control unit 6 is arranged in the machine housing 15 and controls the electric drive motor 5 via a connecting line. For this purpose, the electric drive motor 5 has a sensor which measures the position or the path of the striker 41 and transmits it to the control unit 6. The controller 6 can thus determine the necessary drive torque or the required speed based on a desired drive profile and drive the drive motor 5 exactly.

Das Antriebsprofil wird von dem Steuergerät 6 automatisch ermittelt, indem aus einer Auswahl mehrerer parallel in dem Speicher 61 abgespeicherten Antriebsprofilen ein bestimmtes Antriebsprofil ausgewählt wird. Als Kriterien für die Auswahl des Antriebsprofils dienen dabei Parameter, wie die Art des Schneidguts, der Durchmesser des Schneidguts, die Dicke der abgetrennten Scheiben sowie das gewünschte Ablagebild und/oder die gewünschte Schnittgeschwindigkeit. Diese Kriterien werden dem Steuergerät 6 von einer zentralen Schneidemaschinensteuerung übermittelt, oder über eine Eingabevorrichtung 7 direkt eingegeben.The drive profile is determined automatically by the control unit 6 by selecting a specific drive profile from a selection of a plurality of drive profiles stored in parallel in the memory 61. As criteria for the selection of the drive profile serve parameters such as the type of material to be cut, the diameter of the material to be cut, the thickness of the separated slices and the desired storage image and / or the desired cutting speed. These criteria are transmitted to the control unit 6 from a central cutting machine control, or entered directly via an input device 7.
