Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Aufschneiden von Lebensmittelprodukten, insbesondere Wurst, Fleisch oder Käse, mit einer Zuführeinrichtung, mit der wenigstens ein Produkt in einer Förderrichtung gefördert und einem der Zuführeinrichtung nachgeordneten Schneidmesser zugeführt werden kann, wobei die Zuführeinrichtung zumindest einen Schlitten aufweist, an dem wenigstens ein mit dem Produkt zusammenwirkender Produkthalter angeordnet ist, und wobei der Schlitten längs der Förderrichtung bewegbar ist.The present invention relates to a device for slicing food products, in particular sausage, meat or cheese, with a feeding device, with which at least one product can be conveyed in a conveying direction and fed to a cutting device arranged downstream of the feeder, wherein the feeding device has at least one slide at least one product holder cooperating with the product is arranged, and wherein the carriage is movable along the conveying direction.

Vorrichtungen zum Aufschneiden von Lebensmittelprodukten werden auch als Aufschneidemaschinen oder Slicer bezeichnet. Bei bekannten Vorrichtungen der eingangs genannten Art ist der Antrieb der Zuführeinrichtung als Spindel ausgebildet, die rotierend antreibbar ist. Bei der Spindel handelt es sich somit um einen rotierenden Antrieb für den Schlitten. Dabei ist der Schlitten mittels einer auf der Spindel aufgefädelten Mutter mit der Spindel gekoppelt, so dass die rotierende Bewegung der Spindel in eine translatorische Bewegung des Schlittens umgesetzt und der Schlitten längs der Förderrichtung verfahren werden kann. Der über die Spindel realisierte Antrieb für den Schlitten ist relativ aufwändig, auch hinsichtlich der zum Schutz bzw. der Reinigung der Spindel erforderlichen Maßnahmen.Devices for slicing food products are also referred to as slicers or slicers. In known devices of the type mentioned, the drive of the feeder is designed as a spindle which is driven in rotation. The spindle is thus a rotating drive for the slide. In this case, the carriage is coupled by means of a threaded on the spindle nut with the spindle, so that the rotating movement of the spindle can be converted into a translational movement of the carriage and the carriage can be moved along the conveying direction. The realized via the spindle drive for the carriage is relatively complex, also in terms of the protection or cleaning of the spindle required measures.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine verbesserte Zuführeinrichtung zu schaffen, die mit geringem Aufwand realisierbar ist und mittels der auf einfache und zuverlässige Weise der Schlitten angetrieben werden kann.The present invention is based on the object to provide an improved feeding, which can be realized with little effort and by means of which the carriage can be driven in a simple and reliable manner.

Die Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst und insbesondere dadurch, dass der Schlitten mit einem Linearantrieb gekoppelt ist, mittels dem der Schlitten längs der Förderrichtung verfahrbar ist.The object is achieved by a device having the features of claim 1 and in particular by the fact that the carriage is coupled to a linear drive, by means of which the carriage along the conveying direction is movable.

Bei der erfindungsgemäβen Vorrichtung wird der Schlitten somit durch einen Linearantrieb angetrieben. Dieser kann gegenüber einem Spindelantrieb einfacher in die Aufschneidevorrichtung integriert werden. Zudem verschmutzt der Linearantrieb im Vergleich zum Spindelantrieb weniger stark bzw. der Linearantrieb lässt sich einfacher reinigen.
Vorteilhaft ist ferner, dass der Linearantrieb direkt eine lineare Antriebsbewegung für den Schlitten erzeugt, so dass es nicht - wie bei einer Spindel - erforderlich ist, eine Drehbewegung in eine lineare Bewegung für den Schlitten umzusetzen. Gleichwohl erlaubt auch der Linearantrieb die Übertragung ausreichend großer Kräfte und die Ausführung hochpräziser und reproduzierbarer Zuführbewegungen.In the device according to the invention, the carriage is thus driven by a linear drive. This can be easily integrated into the slicing device compared to a spindle drive. In addition, the linear drive contaminates less than the spindle drive or the linear drive is easier to clean.
It is also advantageous that the linear drive directly generates a linear drive movement for the carriage, so that it is not necessary - as in a spindle - to implement a rotational movement in a linear movement for the slide. Nevertheless, the linear drive allows the transmission of sufficiently large forces and the execution of high-precision and reproducible feed movements.

Bevorzugt weist der Linearantrieb einen elektromagnetischen Linearmotor mit einem längs der Förderrichtung verlaufenden Stator und einem entlang des Stators verfahrbaren Läufer auf, welcher von dem Schlitten gebildet ist. Derartige elektromagnetische Linearmotoren werden auch als Wanderfeldmotoren bezeichnet.The linear drive preferably has an electromagnetic linear motor with a stator extending along the conveying direction and a rotor which can be moved along the stator and which is formed by the carriage. Such electromagnetic linear motors are also referred to as traveling-field motors.

Durch einen elektromagnetischen Linearmotor kann der Linearantrieb besonders einfach und verhältnismäßig kostengünstig realisiert werden. Auβerdem lassen sich derartige Linearmotoren auf elektrischem Wege einfach betreiben und steuern. Insbesondere eine exakte Ansteuerung und Verstellung des Linearmotors kann beispielsweise mittels einer, insbesondere digitalen, Steuerung und/oder Regelung einfach realisiert werden.By an electromagnetic linear motor, the linear drive can be realized in a particularly simple and relatively inexpensive. Moreover, such linear motors can be easily operated and controlled by electrical means. In particular, an exact control and adjustment of the linear motor can be easily realized for example by means of a, in particular digital, control and / or regulation.

Besonders bevorzugt umfasst der Schlitten zumindest einen Magneten, insbesondere Permanentmagneten, und am Stator ist zumindest eine bestrombare Spule zur Erzeugung eines mit dem Magneten wechselwirkenden Magnetfelds vorgesehen, durch das der Schlitten entlang des Stators bewegt werden kann. Das Magnetfeld kann beispielweise derart erzeugt werden, dass es sich entlang des Stators fortbewegt und dabei - in an sich bei einem elektromagnetischen Linearmotor bekannter Weise - den magnetischen Schlitten mit sich zieht. An am Schlitten vorgesehenen Permanentmagneten ist insbesondere vorteilhaft, dass keine elektrischen Stromleitungen zum Schlitten geführt werden müssen, die demzufolge beim Verfahren des Schlittens auch nicht mitgeführt werden müssen.Particularly preferably, the carriage comprises at least one magnet, in particular permanent magnets, and at least one energizable coil for generating a magnetic field interacting with the magnet is provided on the stator, by means of which the carriage can be moved along the stator. The magnetic field can be generated, for example, so that it moves along the stator and thereby - in itself in an electromagnetic linear motor known manner - pulls the magnetic slide with it. At permanent magnets provided on the slide is particularly advantageous that no electrical power lines must be guided to the carriage, which therefore also do not have to be carried during the process of the carriage.

Nach einer weiteren Ausgestaltung der Erfindung umfasst der Schlitten zumindest eine bestrombare Spule und entlang des Stators können Magnete, insbesondere Permanentmagnete, angeordnet sein, die mit dem von der Spule erzeugbaren Magnetfeld derart zusammenwirken, dass der Schlitten entlang des Stators bewegt werden kann. Bei dieser Ausgestaltung ist es somit erforderlich, dass die Spule des Schlittens bestromt wird, während die Magnete des Stators unbestromt sein können.According to a further embodiment of the invention, the carriage comprises at least one energizable coil and along the stator magnets, in particular permanent magnets, can be arranged, which cooperate with the magnetic field generated by the coil such that the carriage can be moved along the stator. In this embodiment, it is thus necessary that the coil of the carriage is energized, while the magnets of the stator can be energized.

Nach einer anderen bevorzugten Ausgestaltung der Erfindung weist der Linearantrieb wenigstens einen längs der Förderrichtung bewegbaren Mitnehmer auf, der, insbesondere berührungslos, mit dem Schlitten derart gekoppelt ist, dass der Schlitten einer Bewegung des Mitnehmers längs der Förderrichtung folgt.According to another preferred embodiment of the invention, the linear drive has at least one movable along the conveying direction carrier, which is in particular contactlessly coupled to the carriage such that the carriage follows a movement of the driver along the conveying direction.

Bevorzugt ist der Mitnehmer über zumindest ein, insbesondere permanentes, Magnetfeld mit dem Schlitten gekoppelt. Die berührungslose Kopplung zwischen dem Mitnehmer und dem Schlitten kann besonders einfach mittels des Magnetfelds realisiert werden. Dabei lassen sich auch starke Magnetfelder relativ einfach erzeugen.The driver is preferably coupled to the carriage via at least one, in particular permanent, magnetic field. The contactless coupling between the driver and the carriage can be realized particularly easily by means of the magnetic field. It is also possible to generate strong magnetic fields relatively easily.

Besonders bevorzugt umfassen der Mitnehmer und/oder der Schlitten jeweils zumindest einen Magneten, insbesondere einen Permanentmagneten. Zum Beispiel durch einen am Mitnehmer angebrachten oder den Mitnehmer bildenden Magneten und einem am Schlitten angebrachten Gegenmagneten kann das Magnetfeld zur Kopplung des Mitnehmers mit dem Schlitten besonders einfach erzeugt werden. Die Verwendung von Permanentmagneten hat insbesondere den Vorteil, dass diese kostengünstig und störungsunanfällig sind und damit ein dauerhaftes Magnetfeld erzeugt werden kann.Particularly preferably, the driver and / or the carriage each comprise at least one magnet, in particular a permanent magnet. For example, by a magnet attached to the driver or forming the driver and a counter-magnet mounted on the slide, the magnetic field for coupling the driver to the slide can be generated particularly easily. The use of permanent magnets has the particular advantage that they are inexpensive and trouble-prone and thus a permanent magnetic field can be generated.

Nach einer bevorzugten Weiterbildung der Erfindung umfasst der Linearantrieb zumindest einen doppeltwirkenden Hydraulikzylinder, dessen Kolben von dem Mitnehmer gebildet ist und wobei der Schlitten längs der Hydraulikzylinders bewegt werden kann. Der Mitnehmer ist somit innerhalb des Hydraulikzylinders angeordnet und aufgrund der Doppelwirkung des Hydraulikzylinders von beiden Seiten mit Hydraulikflüssigkeit beaufschlagbar. Dadurch kann die Position des Mitnehmers sowohl in Förderrichtung als auch entgegen der Förderrichtung mittels der im Hydraulikzylinder vorhandenen Hydraulikflüssigkeit mit hoher Genauigkeit eingestellt werden.According to a preferred embodiment of the invention, the linear drive comprises at least one double-acting hydraulic cylinder whose piston is formed by the driver and wherein the carriage can be moved along the hydraulic cylinder. The driver is thus arranged within the hydraulic cylinder and can be acted upon by hydraulic fluid from both sides due to the double action of the hydraulic cylinder. Thereby, the position of the driver can be adjusted both in the conveying direction and against the conveying direction by means of hydraulic fluid present in the hydraulic cylinder with high accuracy.

Ein Hydraulikzylinder ist vorteilhaft, da aufgrund der geringen Kompressibilität der Hydraulikflüssigkeit die Position des Mitnehmers längs des Hydraulikzylinders mit extrem hoher Genauigkeit eingestellt werden kann, so dass jedes gewünschte Bewegungsprofil für den Schlitten mit hoher Genauigkeit realisiert werden kann. Auβerdem können mittels der Hydraulikflüssigkeit auch vergleichsweise hohe Kräfte auf den Mitnehmer übertragen werden.A hydraulic cylinder is advantageous because, due to the low compressibility of the hydraulic fluid, the position of the driver along the hydraulic cylinder can be adjusted with extremely high accuracy, so that any desired motion profile for the slide can be realized with high accuracy. In addition, comparatively high forces can be transmitted to the driver by means of the hydraulic fluid.

Nach einer bevorzugten Ausgestaltung der Erfindung ist der Mitnehmer in einem längs der Förderrichtung verlaufenden, insbesondere zylinderförmigen, Hohlraum angeordnet. Wie vorstehend erwähnt wurde, ist bei aus dem Stand der Technik bekannten Vorrichtungen eine Spindel als Antrieb für den Schlitten vorgesehen. Dabei ist es insbesondere aus hygienischen Gründen und zum Schutz der Spindel vor Verschmutzung erforderlich, dass die Spindel in einem Gehäuse untergebracht ist. Demgegenüber kann durch die erfindungsgemäβe Anordnung des Mitnehmers in dem Hohlraum ein zusätzliches Gehäuse entfallen. Entsprechendes gilt für den vorstehend genannten Hydraulikzylinder. Dadurch verringert sich der Herstellungsaufwand für die Vorrichtung. Auβerdem kann die Vorrichtung kompakter gebaut werden, da an der Vorrichtung kein zusätzlicher Bauraum für ein Gehäuse vorgesehen werden muss.According to a preferred embodiment of the invention, the driver is arranged in a longitudinal direction of the conveying direction, in particular cylindrical, cavity. As mentioned above, in prior art devices, a spindle is provided to drive the carriage. It is necessary in particular for reasons of hygiene and to protect the spindle from contamination that the spindle is housed in a housing. In contrast, can account for an additional housing by the erfindungsgemäβe arrangement of the driver in the cavity. The same applies to the above-mentioned hydraulic cylinder. This reduces the manufacturing cost of the device. In addition, the device can be made more compact, since no additional space for a housing must be provided on the device.

Nach einer Weiterbildung der Erfindung unterteilt der Mitnehmer den Hohlraum in einen ersten Hohlraumabschnitt und einen zweiten Hohlraumabschnitt, der in Förderrichtung betrachtet hinter dem ersten Hohlraumabschnitt liegt, wobei zumindest ein Hohlraumabschnitt mit Hydraulikflüssigkeit beaufschlagbar ist, um den Mitnehmer zu bewegen. Der Hohlraumabschnitt kann somit beispielsweise nach Art eines einfachwirkenden oder eines doppeltwirkenden Hydraulikzylinders ausgestaltet sein, so dass der Mitnehmer mittels Hydraulikflüssigkeit längs der Förderrichtung bewegbar ist.According to a development of the invention, the driver divides the cavity into a first cavity section and a second cavity section, which, viewed in the conveying direction, lies behind the first cavity section, wherein at least one cavity section can be acted upon by hydraulic fluid in order to move the driver. The cavity section can thus be designed, for example, in the manner of a single-acting or a double-acting hydraulic cylinder, so that the driver can be moved along the conveying direction by means of hydraulic fluid.

Vorzugsweise sind beide Hohlraumabschnitte mit Hydraulikflüssigkeit gefüllt und jeweils mit einer Zu-/Ableitung für Hydraulikflüssigkeit verbunden, mittels der Hydraulikflüssigkeit in den jeweiligen Hohlraumabschnitt geleitet oder aus dem jeweiligen Hohlraumabschnitt entnommen werden kann.Preferably, both cavity sections are filled with hydraulic fluid and in each case connected to a supply / discharge line for hydraulic fluid, can be directed by means of the hydraulic fluid into the respective cavity section or removed from the respective cavity section.

Bei der Hydraulikflüssigkeit kann es sich um lebensmitteltaugliches Öl oder Wasser handeln.The hydraulic fluid may be food grade oil or water.

Bevorzugt ist der Linearantrieb gleichzeitig als Führung für den Schlitten ausgebildet. Antrieb und Führung verschmelzen so zu einer Einheit, so dass die Aufschneidevorrichtung kompakter gebaut werden kann.Preferably, the linear drive is at the same time designed as a guide for the carriage. Drive and guide merge into a single unit so that the slicing device can be made more compact.

Die Führung kann ein Rohr umfassen, dessen Längsachse in Förderrichtung verläuft.The guide may comprise a tube whose longitudinal axis extends in the conveying direction.

Bei einer bevorzugten Weiterbildung der Erfindung weist der Schlitten eine Hülse, insbesondere eine Gleithülse, auf, mittels welcher der Schlitten an dem Rohr beweglich angeordnet ist, wobei die Hülse das Rohr umgibt und der Mitnehmer innerhalb des Rohres angeordnet ist.In a preferred embodiment of the invention, the carriage on a sleeve, in particular a sliding sleeve, on, by means of which the carriage is movably disposed on the tube, wherein the sleeve surrounds the tube and the driver is disposed within the tube.

Es kann eine Steuerung vorgesehen sein, mittels der die Position des Schlittens einstellbar und/oder ein vorgegebenes Bewegungs- oder Geschwindigkeitsprofil für den Schlitten längs der Förderrichtung realisierbar ist. Die Steuerung kann mit der eigentlichen Steuerung der Aufschneidevorrichtung gekoppelt oder in diese integriert sein.A control may be provided by means of which the position of the carriage can be adjusted and / or a predetermined movement or speed profile for the carriage along the conveying direction can be realized. The controller may be coupled to or integrated with the actual control of the slicing apparatus.

Das Produkt kann mittels des Schlittens in der Förderrichtung gefördert werden. Die Zuführeinrichtung kann auch ein an sich bekanntes Endlosförderband aufweisen, auf dem das Produkt aufliegt und mit dem das Produkt gefördert wird. Der Schlitten und der Produkthalter können somit zum Beispiel mit dem Produkt mitbewegt bzw. mitgefahren werden, ohne dass das Produkt durch den Schlitten bzw. den Produkthalter gefördert wird, um beispielsweise erst gegen Ende des Aufschneidevorgangs den Produkthalter mit dem Produkt in Eingriff zu bringen.The product can be conveyed by means of the carriage in the conveying direction. The feeder may also comprise a per se known endless conveyor belt on which the product rests and with the Product is promoted. The carriage and the product holder can thus be moved along with the product, for example, without the product being conveyed through the carriage or the product holder in order, for example, to bring the product holder into engagement with the product only towards the end of the slicing process.

Der Begriff "Produkthalter" ist breit auszulegen. Es kann sich dabei nicht nur um eine Einrichtung handeln, die das Produkt hält. Vielmehr kann darunter auch eine Einrichtung verstanden werden, die irgendwie mit dem Produkt in Kontakt gebracht und/oder mittels der das Produkt - wie auch immer - gehandhabt werden kann. Der Produkthalter kann beispielsweise ein Produktschieber oder ein Produktniederhalter sein.The term "product holder" is to be interpreted broadly. It can not just be a device that holds the product. Rather, it can also be understood as meaning a device which can somehow be brought into contact with the product and / or by means of which the product can be handled - however it may be. The product holder may be, for example, a product pusher or a product depressor.

Der Produkthalter kann auch als Produktgreifer ausgestaltet sein, der zumindest eine Greifklaue aufweist, welche insbesondere in das hintere, vom Schneidmesser abgewandte Ende des Produkts eingreifen kann. Aufgrund des Eingriffs in das Produkt kann dieses nicht nur in Förderrichtung, sondern auch entgegen der Förderrichtung vom Produkthalter bewegt werden. Beispielsweise kann der Schlitten mit dem als Produktgreifer ausgebildeten Produkthalter dazu vorgesehen sein, das nicht aufgeschnittene hintere Produktende im Anschluss an den Aufschneidevorgang vom Schneidmesser wegzubewegen, also entgegen der Förderrichtung zu bewegen, um diesen Produktrest anschließend in einen Restebehälter abzuwerfen.The product holder can also be designed as a product gripper, which has at least one gripping jaw, which can engage in particular in the rear, remote from the cutting blade end of the product. Due to the intervention in the product this can be moved not only in the conveying direction, but also against the conveying direction of the product holder. For example, the carriage with the product holder designed as a product gripper may be provided for moving the uncut rear end of the product away from the cutting blade following the slicing process, ie moving it counter to the conveying direction in order to then dump this product residue into a residual container.

Die Erfindung betrifft auch eine Zuführeinrichtung für eine Vorrichtung zum Aufschneiden von Lebensmittelprodukten, die einen Schlitten aufweist, der längs einer Förderrichtung bewegbar ist, wobei an dem Schlitten wenigstens ein Produkthalter angeordnet ist, der mit einem Produkt zusammenwirken kann, wobei der Schlitten mit einem Linearantrieb gekoppelt ist, mittels dem der Schlitten längs der Förderrichtung verfahrbar ist.The invention also relates to a feed device for a device for slicing food products, which has a slide which is movable along a conveying direction, wherein on the carriage at least one product holder is arranged, which can interact with a product, wherein the carriage coupled to a linear drive is, by means of which the carriage is movable along the conveying direction.

Die in den Fig. 1 bis 4 dargestellte Vorrichtung 1 ist zum Aufschneiden von Lebensmittelprodukten 3 vorgesehen. Bei der Vorrichtung 1 werden gleichzeitig zwei Produkte 3, die auf einer Produktauflage 5 aufliegen, nebeneinander liegend, also in zwei Spuren, in einer Förderrichtung I einem Schneidmesser 7 zugeführt und von diesem aufgeschnitten. Die Vorrichtung 1 weist eine Zuführeinrichtung 9 auf, die einen Schlitten 11 umfasst, an dem zwei als Produktgreifer ausgebildete Produkthalter 13 angeordnet sind. Jeder Produkthalter 13 weist Greifelemente auf, die mit einem dem Schneidmesser 7 abgewandten hinteren Ende des in der jeweiligen Spur angeordneten Produkts 3 in Eingriff gebracht werden können.The in the Fig. 1 to 4 illustrated device 1 is provided for slicing food products 3. In the device 1 are simultaneously two products 3, which rest on a product support 5, lying side by side, ie in two tracks, in a conveying direction I a cutting blade 7 and cut from this. The device 1 has a feed device 9, which comprises a carriage 11, on which two product holders 13 designed as product grippers are arranged. Each product holder 13 has gripping elements with a rear end of the product arranged in the respective track 3 can be brought into engagement with the cutting blade 7.

Die Zuführeinrichtung 9 weist zudem zwei in Förderrichtung I verlaufende Führungen 15 auf, mittels welcher der Schlitten 11 längs der Förderrichtung I geführt ist. Dabei weist jede Führung 15 ein Rohr 15a auf, dessen Längsachse in Förderrichtung I verläuft. Der Schlitten 11 ist mittels jeweils einer Gleithülse 17 an jedem Rohr 15a angeordnet, so dass der Schlitten 11 entlang der Rohre 15a gleiten und somit längs der Förderrichtung I verfahren werden kann.The feeding device 9 also has two guides 15 extending in the conveying direction I, by means of which the carriage 11 is guided along the conveying direction I. In this case, each guide 15 has a tube 15a, whose longitudinal axis runs in the conveying direction I. The carriage 11 is arranged by means of a respective sliding sleeve 17 on each tube 15a, so that the carriage 11 can slide along the tubes 15a and thus can be moved along the conveying direction I.

Der Schlitten 11 kann dabei durch einen Linearantrieb angetrieben werden, der bei der Vorrichtung 1 folgendermaßen ausgestaltet ist. Der Linearantrieb weist Mitnehmer 19 auf, wobei jeweils ein Mitnehmer 19 im Inneren eines Rohres 15a angeordnet und längs des vom dem jeweiligen Rohr 15a gebildeten Hohlraums bewegbar ist. Dabei ist jeder Mitnehmer 19 mit dem Schlitten 11 über ein Magnetfeld derart gekoppelt ist, dass der Schlitten 11 der Bewegung des Mitnehmers 19 folgt.The carriage 11 can be driven by a linear drive, which is configured as follows in the device 1. The linear drive has drivers 19, wherein in each case a driver 19 is arranged in the interior of a tube 15a and along the cavity formed by the respective tube 15a is movable. In this case, each driver 19 is coupled to the carriage 11 via a magnetic field such that the carriage 11 follows the movement of the driver 19.

Insbesondere unterteilt der Mitnehmer 19 den Hohlraum im Inneren eines Rohres 15a in einen ersten Hohlraumabschnitt 21a und einen zweiten Hohlraumabschnitt 21b. Dabei liegt, wie aus den Fig. 2 und 3 ersichtlich ist, der zweite Hohlraumabschnitt 21b in Förderrichtung I betrachtet hinter dem ersten Hohlraumabschnitt 21a. Beide Hohlraumabschnitte 21a, 21b eines Rohres 15a sind mit einer Zu-/Ableitung 23 für Hydraulikflüssigkeit verbunden, über die Hydraulikflüssigkeit ein- und ausgeleitet werden kann.In particular, the driver 19 divides the cavity inside a tube 15a into a first cavity portion 21a and a second cavity portion 21b. It lies, how from the Fig. 2 and 3 can be seen, the second cavity portion 21b in the conveying direction I viewed behind the first cavity portion 21a. Both cavity sections 21a, 21b of a pipe 15a are connected to a supply / discharge line 23 for hydraulic fluid, via which hydraulic fluid can be introduced and removed.

Jedes Rohr 15a bildet somit einen doppeltwirkenden Hydraulikzylinder, dessen Kolben von dem Mitnehmer 19 gebildet ist. Wie erwähnt, ist jeder der beiden Mitnehmer 19 über ein Magnetfeld mit dem Schlitten 11 derart gekoppelt, dass der Schlitten 11 von den Mitnehmern 19 mitgenommen und somit angetrieben wird, wenn die Mitnehmer 19 längs der Rohre 15a bewegt werden. Das Magnetfeld kann beispielsweise dadurch erzeugt werden, dass an jedem Mitnehmer 19 und am Schlitten 11, insbesondere im Bereich der Gleithülsen 19, Permanentmagnete angeordnet sind, die ein ausreichend starkes Magnetfeld erzeugen, durch das der Schlitten 11 von den Mitnehmern 19 mitgezogen werden kann.Each tube 15a thus forms a double-acting hydraulic cylinder whose piston is formed by the driver 19. As mentioned, everyone is the two drivers 19 coupled via a magnetic field with the carriage 11 such that the carriage 11 is taken away by the drivers 19 and thus driven when the drivers 19 are moved along the tubes 15 a. The magnetic field can be generated, for example, by arranging permanent magnets on each driver 19 and on the carriage 11, in particular in the region of the sliding sleeves 19, which generate a sufficiently strong magnetic field by which the carriage 11 can be pulled along by the drivers 19.

Wie vorstehend erwähnt, sind die Hohlraumabschnitte 21a, 21b jedes Rohres 15a mit Hydraulikflüssigkeit gefüllt, die über die Zu-/Ableitungen 23 zugeführt bzw. abgeleitet werden kann. Dabei kann zum Beispiel die Zu-/Ableitung 23 des Hohlraumabschnitts 23a über eine Hydraulikleitung 25 mit der Zu-/Ableitung 23 des Hohlraumabschnitts 21b desselben Rohres 15a verbunden sein, so dass Hydraulikflüssigkeit über eine dazwischengeschaltete Pumpe 27 zwischen den Hohlraumabschnitten 21a, 21b desselben Rohrs 15a hin- und her gepumpt werden kann. Die Hydraulikleitung 25 und die Pumpe 27 sind in Fig. 3 exemplarisch für eines der beiden Rohre 15a gezeigt.As mentioned above, the cavity portions 21a, 21b of each tube 15a are filled with hydraulic fluid, which can be supplied via the supply / discharge lines 23. At this time, for example, the inflow / outflow 23 of the cavity portion 23a may be connected to the inflow / outflow 23 of the lumen portion 21b of the same tube 15a via a hydraulic line 25, so that hydraulic fluid is supplied through an interposed pump 27 between the lumen portions 21a, 21b of the same tube 15a can be pumped back and forth. The hydraulic line 25 and the pump 27 are in Fig. 3 shown by way of example for one of the two tubes 15a.

In Betrieb werden die Mitnehmer 19 in den beiden Rohren 15a dadurch in Förderrichtung I bewegt, dass in jedem Rohr 15a Hydraulikflüssigkeit aus dem zweiten Hohlraumabschnitt 21b in den ersten Hohlraumabschnitt 21a gepumpt wird. Aufgrund der magnetischen Kopplung wird der Schlitten 11 von den Mitnehmern 19 mitgezogen, so dass sich der Schlitten 11 und damit die Produkthalter 13 ebenfalls in Förderrichtung I bewegen. Um die Mitnehmer 19 und damit den Schlitten 11 und die Produkthalter 19 entgegen der Förderrichtung I zu bewegen, wird in jedem Rohr 19 die Hydraulikflüssigkeit in der umgekehrten Richtung aus dem ersten Hohlraumabschnitt 21a in den zweiten Hohlraumabschnitt 21b gepumpt.In operation, the drivers 19 in the two tubes 15a are thereby moved in the conveying direction I, that in each tube 15a hydraulic fluid from the second cavity portion 21b is pumped into the first cavity portion 21a. Due to the magnetic coupling of the carriage 11 is pulled along by the drivers 19, so that the carriage 11 and thus the product holder 13 also move in the conveying direction I. In order to move the drivers 19 and thus the carriage 11 and the product holder 19 counter to the conveying direction I, the hydraulic fluid in each tube 19 is pumped in the reverse direction from the first cavity portion 21a into the second cavity portion 21b.

Zur Einstellung der Position des Mitnehmers 19 bzw. zum Abfahren eines jeweils gewünschten Bewegungsprofils längs des jeweiligen Rohrs 15a kann eine nicht gezeigte Steuerung vorgesehen sein, die beispielsweise mit Sensoren gekoppelt ist, um jeweils die momentane Position des Mitnehmers 19 zu ermitteln. Die Steuerung kann dann die Pumpe 27 derart ansteuern, dass der Mitnehmer 19 gemäß einem gewünschten Geschwindigkeits- bzw. Bewegungsprofil verfahren wird. Die Steuerung kann insofern in herkömmlicher Weise gemäβ der jeweiligen Anwendung die Produktzufuhr realisieren.In order to adjust the position of the driver 19 or to drive off a respective desired movement profile along the respective tube 15a, a controller, not shown, may be provided, which is coupled, for example, with sensors in order to determine the instantaneous position of the driver 19. The controller can then control the pump 27 such that the driver 19 is moved according to a desired speed or movement profile. The controller can thus implement the product supply in a conventional manner according to the particular application.

Der Schlitten 11 und die Produkthalter 13 können zur Förderung der Produkte 3 vorgesehen sein. Die Produktauflage 5 kann jedoch auch von einem Endlosförderband gebildet werden, mit dem die Produkte 3 gefördert werden. In diesem Falle können der Schlitten 11 und die Produkthalter 13 insbesondere dazu vorgesehen sein, nach dem Aufschneidevorgang die übrigbleibenden, nicht aufgeschnittenen Enden der Produkte 3 entgegen der Förderrichtung I von Schneidmesser 7 wegzubewegen und diese einem Restebehälter zuzuführen.The carriage 11 and the product holder 13 may be provided for conveying the products 3. However, the product support 5 can also be formed by an endless conveyor belt with which the products 3 are conveyed. In this case, the carriage 11 and the product holder 13 may be provided, in particular, to move the remaining, not cut ends of the products 3 away from the conveying direction I of the cutting blade 7 after the slicing process and to supply them to a residual container.

Die in Fig. 5 dargestellte Vorrichtung 1' unterscheidet sich insbesondere durch die Ausgestaltung des Linearantriebs von der Vorrichtung 1 der Fig. 1 bis 4. Bei der Vorrichtung 1' ist der Schlitten 11 mit einem Linearantrieb gekoppelt, der einen elektromagnetischen Linearmotor umfasst, welcher einen längs der Förderrichtung I verlaufenden Stator 29 und einen entlang des Stators 29 verfahrbaren Läufer 31 aufweist, der als Teil des Schlittens 11 ausgebildet ist.In the Fig. 5 illustrated device 1 'differs in particular by the design of the linear drive of the device 1 of Fig. 1 to 4 , In the device 1 ', the carriage 11 is coupled to a linear drive which comprises a linear electromagnetic motor which has a stator 29 extending along the conveying direction I and a rotor 31 movable along the stator 29, which is designed as part of the carriage 11.

Bei der Vorrichtung 1' ist der Läufer 31 an einem quer zur Förderrichtung I liegenden Ende des Schlittens 11 angeordnet. An dem gegenüberliegenden Ende des Schlittens 11 ist eine Gleithülse 33 um eine rohrförmige Führung 35 angeordnet, mittels der der Schlitten 11 längs der Förderrichtung I geführt ist.In the device 1 ', the rotor 31 is arranged at a transverse to the conveying direction I end of the carriage 11. At the opposite End of the carriage 11, a sliding sleeve 33 is arranged around a tubular guide 35, by means of which the carriage 11 is guided along the conveying direction I.

Der Läufer 31 umfasst nicht dargestellte Permanentmagnete. Entlang des Stators 29 sind ebenfalls nicht dargestellte elektrische Spulen angeordnet, durch die ein Magnetfeld erzeugt werden kann, das mit dem Magnetfeld der Permanentmagnete des Läufers 31 derart wechselwirkt, dass der Läufer 31 längs der Förderrichtung I bewegt werden kann. Insbesondere kann durch die Spulen ein entlang des Stators 29 wanderndes Magnetfeld erzeugt werden, durch das der Läufer 31 mitgezogen wird. Dabei kann der Schlitten 11 je nach Bestromung der Spulen in Förderrichtung I oder entgegen der Förderrichtung I bewegt werden. Außerdem ist es möglich, den Schlitten 11 an einer bestimmten Position längs der Förderrichtung I zu halten.The rotor 31 includes permanent magnets, not shown. Along the stator 29 also not shown electric coils are arranged, through which a magnetic field can be generated, which interacts with the magnetic field of the permanent magnets of the rotor 31 such that the rotor 31 along the conveying direction I can be moved. In particular, a magnetic field traveling along the stator 29 can be generated by the coils, through which the rotor 31 is entrained. In this case, the carriage 11 can be moved in the conveying direction I or counter to the conveying direction I, depending on the energization of the coils. In addition, it is possible to keep the carriage 11 at a certain position along the conveying direction I.

Es sind auch alternative Abwandlungen der vorstehend beschriebenen Vorrichtung 1' ohne weiteres möglich. Beispielsweise kann der Stator 29 Permanentmagnete und der Läufer 31 kann bestrombare Spulen aufweisen, mittels denen ein Magnetfeld erzeugt werden kann, das mit den Permanentmagneten derart zusammenwirkt, dass der Läufer 31 längs der Förderrichtung I verfahren werden kann.Alternative modifications of the apparatus 1 'described above are also readily possible. For example, the stator 29 may comprise permanent magnets and the rotor 31 may comprise energizable coils by means of which a magnetic field can be generated which interacts with the permanent magnets such that the rotor 31 can be moved along the conveying direction I.

Auβerdem kann eine weitere Führung auch auf derjenigen Seite der Zuführeinrichtung 9 vorgesehen sein, längs der der Stator 29 verläuft, so dass der Schlitten 11 beidseitig geführt sein kann. Entsprechend kann auch auf der Seite der in Fig. 5 dargestellten Führung 35 ein weiterer elektromagnetischer Linearmotor mit einem sich längs der Förderrichtung I ersteckenden Stator und einem als Teil des Schlittens 11 ausgebildeten Läufer vorgesehen sein (nicht gezeigt). Der Schlitten 11 kann somit auch an seinen beiden quer zur Förderrichtung I liegenden Enden mittels jeweils eines elektromagnetischen Linearmotors angetrieben sein.In addition, a further guide can also be provided on that side of the feed device 9, along which the stator 29 extends, so that the carriage 11 can be guided on both sides. Accordingly, also on the side of in Fig. 5 a further electromagnetic linear motor having a stator extending along the conveying direction I and a rotor formed as part of the carriage 11 may be provided (not shown). The carriage 11 can therefore also be driven at its two transverse to the conveying direction I ends by means of a respective electromagnetic linear motor.

Außerdem ist es möglich, dass die beiderseits des Schlittens 11 angeordneten Linearmotoren gleichzeitig zur Führung des Schlittens 11 dienen, so dass die in Fig. 5 dargestellte, separate Führung 35 entfallen kann.In addition, it is possible that the linear motors arranged on either side of the carriage 11 simultaneously serve to guide the carriage 11, so that the in Fig. 5 shown, separate guide 35 can be omitted.
