Definitions
- the invention relates to a method and a device for cutting a foodstuff, in particular compressible cheese or meat, which is fed to a cutting unit.
- cutting devices e.g. Devices are provided with rotating cutting discs, which are performed at high clock rates against the products to perform the necessary cuts.
- Such devices are expensive to manufacture, in operation and in maintenance. Due to the rotation of the cutting discs, which have to be reground on a regular basis, a massive impact on the material takes place, so that particles are released and thrown away, resulting in contamination of the device.
- the cutting discs and the parameters for their operation are each adapted to the product to be processed, whereby the application is limited or an individual control is provided. If, for example, soft bread is to be cut, then high speeds are required so that it is not compressed when applying a cut. However, if products with different properties are to be processed at the same time, an individual adaptation is hardly possible.
- the producer usually dispenses with an ideal cutting process.
- the clippings are optionally weighed prior to packaging.
- an improved method and a cutting device are to be specified, in which thin slices of foods with high precision and high clock rates can be cut off.
- the sliced food slices should have flat cut surfaces and uniform thicknesses. The precision should be maintained even when the strength properties of the supplied food or parallel feed units changed.
- the cutting device should be simple and can be maintained with little effort.
- the method and apparatus are for cutting a food which is supplied as a unit or in parallel in a plurality of preferably bar-shaped food units.
- the cutting device comprises a cutting unit with at least one cutting tool, a pushing unit with at least one pushing tool, at least one driving device for driving the cutting tool and the pushing tool, and a conveying table on which the food is deposited and pushed by the pushing tool towards the cutting tool.
- the drive device is controlled in a work cycle such that the pusher tool in a first cycle section detects the food on the back and pushes towards the cutting tool and is released from the food and withdrawn, after which in a second cycle section the cutting tool is guided against the food and on the front of the food is cut off a food slice.
- the food Before carrying out the cutting process, the food is thus conveyed against the cutting tool and relieved by the pushing tool. Therefore, when performing the cutting operation during which a blade is passed through the food, no pushing forces are applied to the food and the blade.
- the blade is loaded only with forces that run parallel to it, which is why the cut can be performed with maximum precision. Since the food is also loaded only with forces that are perpendicular to it, deformations of the food are avoided and achieved flat cut surfaces.
- the cuts can be carried out with a cutting tool with a blade which is supplied with ultrasonic energy at least during the cutting process.
- the cutting unit preferably comprises a bearing device, by means of which at least one ultrasonic generator is held vertically displaceably, which is connected via a coupling element with a blade.
- the blade is thus held by the ultrasonic generator.
- a mounting surface is provided on the back of the blade or an extremity formed thereon, on which a first end piece of an arcuate, preferably U-shaped coupling element is welded, the second end piece has a connecting element, preferably a threaded bore, which is detachable with the ultrasonic generator connected is.
- the coupling element is for example a bent rod with a round profile or a polygonal profile, which is aligned with the first end piece preferably perpendicular to the blade back and thus perpendicular to the cutting direction and parallel to the transport direction of the food.
- the foodstuff is wholly or partly stored on a support region of an elastic element, which is compressed during the advancement of the food in the support area and stretches after releasing the pushing tool in the support area.
- the elastic element undergoes during the delivery process a similar force as the food. That is, the food and the respective portion of the elastic element in the contact area of the food are compressed during the feed under the action of the pushing tool. After retraction of the pusher, the food can relax. The relaxation of the food is actively supported by the elastic element, which also expands. After retraction of the pushing tool, a rapid reduction of the forces within the food and thus a reduction of the deformation of the food takes place before carrying out the cutting process.
- the single or multi-part conveyor table on several parallel aligned conveying channels, in each of which at least one elastic element is arranged and in which cylindrical or rod-shaped parts of the food can be promoted.
- the elastic element is for example a stored on the conveyor table elastic bearing plate. If delivery channels are provided, at least one rope-shaped, cord-shaped or belt-shaped elastic element is arranged in each delivery channel.
- two string-shaped or belt-shaped elastic elements extend parallel to each other, the ends of which are held in the input area and in the outlet area of the associated conveyor channel and possibly interconnected.
- the elastic elements are preferably arranged symmetrically in each conveying channel, so that the food is supported evenly on both sides.
- elastic elements which consist of elastomers, preferably fluoroelastomers.
- a hold-down device which has a rotatably and elastically held rod, to which a preferably elastic hold-down plate is preferably fastened for each of the conveying channels.
- any foods such as meat products, cheese, vegetables, or bread
- FIG. 1a shows an inventive device 10, which is suitable for cutting various foods 8.
- the device 10 comprises a cutting unit 1 with four cutting tools 11A, ..., 11D, a pushing unit 2 with a pushing tool 21, two driving devices 12, 22 for driving the cutting tools 11 and the pushing tool 21, and a conveyor table 3, on which the food 8 can be deposited and pushed by the pusher 21 toward the cutting tools 11A, ..., 11D.
- Said parts 1, 2, 3 and 4 of the device 10 are held by a mounting structure 5, which consists of longitudinal struts, cross braces and columns, which are not shown in order not to cover the device parts 1, 2, 3 and 4.
- the food 8 is fed in parallel to the four cutting tools 11A, ..., 11D in twelve cylindrical or rod-shaped units 8A, ..., 8L so that three of the food units 8A, ..., 8L of each of the cutting tools 11A; ...; 11D cut simultaneously.
- the parallel-fed food units 8A, ..., 8L are held in a desired position by a blank holder 4 while the cut is being performed.
- the cutting unit 1 comprises the four cutting tools 11A; ...; 11D (see also FIG. 6 ), which in this preferred embodiment are each connected to an ultrasound generator 13 and can be vertically lowered by drive devices 12A, 12B and lifted again to cut food slices 81 from the food units 8.
- the food slices 81 fall on a conveyor belt 92 of a receiving conveyor 9, which has a drive motor 91.
- a control unit 6 which can control the cutting unit 1, the pushing unit 2, the ultrasonic generators 13 and the take-off conveyor 9.
- the control unit 6 is connected to the cutting unit 1 via a first control line 61, a second control line 62 to the push unit 22, a third control line 63 to the ultrasonic generators 13, and a fourth control line 69 connected to the removal conveyor 9.
- the control unit 6 can be supplied via a keyboard 60 and by measuring devices 68, such as measurement formers and sensors, information by means of which the cutting process and the conveying process can be controlled.
- information about the positions of the food units 8 is determined by means of first sensors 68.
- second sensors 67 further process variables can be determined.
- the temperature and consistency of the foodstuffs are measured and, depending on this, the ultrasonic frequency, the cutting speed and the pushing speed are set.
- an application program is provided for controlling all processes, in particular the cutting processes and conveying processes.
- the cutting processes and conveying processes run cyclically and out of phase in common working cycles.
- the 8A,..., 8L are grasped by the pushing tool 21 on the rear side and pushed against the cutting tool 11.
- the pusher 21 is released and retracted by the food units 8A, ..., 8L.
- the cutting tools 11A, ..., 11D guided vertically against the food units 8, with a food slice 81 cut off at the front of each food unit 8A, ..., 8L.
- the cutting tools 11A, ..., 11D are again guided vertically upwards, so that the front sides of the food units 8A, ..., 8L are exposed again.
- the food units 8A, ..., 8L become the next one Work cycle again sequentially detected by the pushing tool 21 and processed by the cutting tools 11A, ..., 11D.
- the duration of the two sections of the working cycle is preferably selected depending on the nature of the food units 8A, ..., 8L. While in the processing of food units 8A, ..., 8L with higher strength, the pushing operation is performed faster and thus shorter first cycle sections are selected, the cutting operation is preferably done somewhat slower, so longer second cycle sections are selected.
- Food units 8A, ..., 8L with lower strength are preferably conveyed more slowly and can be cut faster for this purpose.
- the same food units 8A, ..., 8L may have different strengths at higher and lower temperatures, for which reason the length of the cycle sections is preferably chosen taking into account the measured temperatures.
- the frequency of the ultrasonic energy is preferably selected depending on the nature and temperature of the food units 8A, ..., 8L.
- the food units 8A, ..., 8L can relax and resume their original shape, and thus food slices 81 can be precisely cut off.
- pressure from the pusher tool is prevented from being exerted on the blades of the cutting tools 11A, ..., 11D.
- FIG. 2 shows a part of the device 10 of FIG. 1 with the cutting unit 1, the pushing unit 2 and the conveyor table 3, which consists of two parts 31, 32.
- the conveyor table 3 has twelve conveyor channels 33A, ..., 33L in which the bar-shaped food units 8A, ..., 8L are stored and be conveyed parallel to each other.
- the conveying channels 33A, ..., 33L there are provided pairs of cord-shaped, rope-shaped or belt-shaped elastic members 34A, ..., 34L, preferably at the same height on each side of a channel wall of one of the conveying channels 33A, ..., 33L arranged and stretched over the entire length of the conveyor table 3.
- the pairs of elastic members 34A, ..., 34L are connected to each other on both sides of the conveyor table 3 and form a self-contained O-ring which is stretched over the conveyor table 3.
- Each of the bar-shaped food units 8A, ..., 8L is therefore supported by a pair of elastic members 34A, ..., 34L.
- the surface texture and the elasticity of the elastic elements 34A, ..., 34L are selected such that the portion of the elastic elements 34A, ..., 34L in the contact area of the food units 8A, ..., 8L during the advancement of the food units 8A , ..., 8L is compressed and stretches after releasing the pushing tool 21 in the support area.
- the front sides of the food units 8A, ..., 8L held by hold-down plates 43A, ..., 43L of a blank holder 4 are pushed over the elastic members 34A, ..., 34L, while the elastic members 34A,. ., 34L are at least partially compressed as far as the food units 8A, ..., 8L are compressed.
- the pusher tool 21 which has a pusher plate 21A, ..., 21L for each of the food units 8A, ..., 8L
- the aforementioned relaxation of the food units 8A, ..., 8L takes place with the assistance of the elastic members 34A, ..., 34L, whereby at the same time any deformation on the front side of the food units 8A, ..., 8L is canceled.
- the relaxation takes place in a very short time.
- the elastic members 34A, ..., 34L adapt to the stored food units 8A, ..., 8L, and therefore differences between the food units 8A, ..., 8L are automatically compensated.
- the elastic members 34A, ..., 34L are therefore different if the individual food units 8A, ..., 8L have different holidays.
- the support in the promotion, positioning and relaxation of the food units 8A, ..., 8L thus takes place with simple measures, which means that it is possible to dispense with complex measuring devices and control devices which could alternatively be used to achieve an increased accuracy of the cutting process.
- the high precision can therefore be achieved with the precisely operating pushing unit 2 and the cutting device 1 according to the invention.
- the thrust unit 2 in FIG. 7
- the thrust drive 22 comprises a drive motor 221, which has a drive wheel 223, a drive belt 224 and two thrust wheels 225 with two thrust belts 226A, 226B is coupled to which the pushing tool 21 is coupled by means of coupling elements 227.
- the pusher tool 21 is therefore driven by two push belts 226A, 226B and parallel to the cutting tools 11A, ..., 11D kept aligned. This will ensure that all food units 8A, ..., 8L are advanced evenly.
- FIG. 3 shows the device 10 of FIG. 2 with the pushing unit 2 from the other side.
- the second part 32 of the conveyor table 3 is not shown, so that the remaining elastic elements 34A, ..., 34L are visible.
- the first elastic element 34A was further removed from the conveyor table 3 and is shown isolated.
- the elastic member 34A is a self-contained ring having two portions 34A1, 34A2 which are parallel to each other within the associated conveying channel 33A.
- FIG. 3 further shows the first push belt 226A, which is also coupled to the pushing tool 21 by a coupling element 227.
- FIG. 4 shows the device 10 of FIG. 3 from below with the first part 31 of the conveyor table 3, on the front side, the elastic elements 34A, ..., 34L are attached. Furthermore, a plate-shaped elastic element 340 is shown, which can be placed on the conveyor table 3 instead of the cord-shaped elastic elements 34A, ..., 34L in order to store larger food pieces 8 and to process them according to the invention.
- the plate-shaped elastic member 340 similarly promotes relaxation of the conveyed food 8 and thus promotes precise performance of the cutting operation.
- FIG. 4a shows the attachment of the cord-shaped elastic members 34A, ..., 34L on the back of the second part 32 of the conveyor table 3.
- the elastic elements 34A, ..., 34L each circumscribe a bolt 35 which is preferably provided with a circular groove the associated elastic element 34 is held.
- FIG. 4b shows the attachment of the string-shaped elastic members 34A, ..., 34L on the front side of the first part 31 of the conveyor table 3.
- the conveyor table 3 has front mounting holes 36 in which the elastic members 34A, ..., 34L are held.
- the elastic elements 34A, ..., 34L are used, for example, at the front in a hook-shaped cutout within the mounting openings 36, stretched over the conveyor table 3 and hooked on the rear side to the associated bolt 35.
- FIG. 5 shows a part of the device 10 of FIG. 1 with the hold-down 4, by means of which the supplied food units 8A, ..., 8L can be held in the cutting region of the cutting tools 11A, ..., 11D.
- the holding-down device 4 comprises a rod 41, which is rotatably mounted on both sides by means of shafts 42 and on which a hold-down plate 43,..., 43L is arranged for each conveying channel 33A,..., 33L.
- elastic hold-down plates 43, ..., 43L made of plastic are provided, which extend parallel to the conveying channels 33A, ..., 33L.
- the shaft 42 shown is pivotally connected via a lever 44 to a rod 45, the two spring elements 46A, 46B are held on both sides of nuts 47A, 47B. Between the spring elements 46A, 46B, the rod 45 is held by a holding arm 48, which is connected via a retaining strip 49 with the mounting structure 5 of the cutting device 10. By means of the rod 45 and the spring elements 46A, 46B, the lever 44 is held in a central position and can be rotated with appropriate force on both sides.
- the hold-down 4 can therefore adapt flexibly to volume changes of the food units 8A, ..., 8L.
- FIG. 6 shows the dismantled cutting unit 1 of the device 10 of FIG. 1 , the two identically constructed Includes cutting modules, which are held by a mounting plate which is part of the mounting structure 5 of the device 10.
- Each of the cutting modules comprises a drive unit 12A; 12B and a bearing device 120A connected to the mounting structure 5; 120B, which allows a respective first and second bearing block 16A, 16B to lower and raise vertically.
- two ultrasonic generators 13A, 13B and 13C, 13D are arranged, which are each connected via a coupling element 15 with a cutting tool 11A, 11B, 11C or 11D.
- the cutting tools 11A, ..., 11D each comprise a blade, at the back of which the arcuate coupling elements 15 are welded, whereby the ultrasonic energy can be advantageously coupled into the blades.
- FIG. 7 shows the pushing unit 2 of FIG. 1 from underneath.
- the pushing tool 21 is held by a carriage 23 which is slidable along rails 25A, 25B fixed to two mounting brackets of the mounting structure 5.
- the drive unit 22 is also held with the drive motor 221, which is coupled via a drive wheel 223, a drive belt 224 and two push wheels 225A, 225B with two push belts 226A, 226B, to which the push tool 21 is coupled by means of coupling elements 227.
- the sliding tool 21 held by a vertically displaceable push rod 24 is also telescopically extendable.
- the pushing tool 21 remains horizontally aligned in every vertical position after the extension of the push rod 24.
- the pusher 21 can therefore be lowered and raised by means of a pneumatic drive, whose connections 28 are shown, and moved back and forth by means of the carriage 23.
- food units 8A, ..., 8L of any dimensions on the backside can be centrally grasped and pushed forward.

Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schneiden eines Nahrungsmittels, insbesondere von komprimierbarem Käse oder Fleisch, welches einer Schneideinheit zugeführt wird.The invention relates to a method and a device for cutting a foodstuff, in particular compressible cheese or meat, which is fed to a cutting unit.
In zahlreichen industriellen Anwendungen, insbesondere in der Nahrungsmittelindustrie, sind Produkte mit vorgesehenen Abmessungen bereitzustellen. Oft werden Brot, Fleischwaren, insbesondere Wurstwaren, oder Käse in Tranchen aufgeteilt und verpackt. Dazu werden Schneidvorrichtungen, z.B. Vorrichtungen mit rotierenden Schneidscheiben vorgesehen, welche mit hohen Taktfrequenzen gegen die Produkte geführt werden, um die erforderlichen Schnitte auszuführen. Derartige Vorrichtungen sind aufwendig in der Herstellung, im Betrieb und in der Wartung. Durch die Rotation der Schneidscheiben, die regelmässig neu geschliffen werden müssen, erfolgt eine massive Einwirkung auf das Material, so dass Partikel herauslöst und weggeschleudert werden, wodurch eine Verschmutzung der Vorrichtung resultiert.In many industrial applications, especially in the food industry, products of the intended dimensions must be provided. Often bread, meat products, in particular sausages, or cheese are divided into pieces and packed. For this purpose, cutting devices, e.g. Devices are provided with rotating cutting discs, which are performed at high clock rates against the products to perform the necessary cuts. Such devices are expensive to manufacture, in operation and in maintenance. Due to the rotation of the cutting discs, which have to be reground on a regular basis, a massive impact on the material takes place, so that particles are released and thrown away, resulting in contamination of the device.
Weiterhin sind die Schneidscheiben und die Parameter für deren Betrieb jeweils an das zu verarbeitende Produkt anzupassen, wodurch der Einsatzbereich beschränkt ist oder eine individuelle Ansteuerung vorzusehen ist. Sofern beispielsweise weiches Brot geschnitten werden soll, so sind hohe Drehzahlen erforderlich, damit dieses bei der Applikation eines Schnittes nicht zusammengedrückt wird. Sofern gleichzeitig Produkte mit unterschiedlichen Eigenschaften verarbeitet werden sollen, ist eine individuelle Anpassung jedoch kaum möglich.Furthermore, the cutting discs and the parameters for their operation are each adapted to the product to be processed, whereby the application is limited or an individual control is provided. If, for example, soft bread is to be cut, then high speeds are required so that it is not compressed when applying a cut. However, if products with different properties are to be processed at the same time, an individual adaptation is hardly possible.
Zudem nehmen die rotierenden Schneidscheiben zusammen mit den Antriebsvorrichtungen viel Raum in Anspruch, so dass hinsichtlich der eingesetzten Mittel, einschliesslich der benötigten Räumlichkeiten, eine geringe Effizienz resultiert. Ferner resultieren bei Produkten mit grossen Abmessungen besondere Anforderungen an die Schneideeinheit. Gegebenenfalls muss die Schneidscheibe entlang einer Bahn geführt werden, um den gewünschten Schnitt in der erforderlichen Länge auszuführen.In addition, take the rotating cutting discs together with the drive devices much space, so that with regard to the means used, including the required premises, low efficiency results. Furthermore, special requirements for the cutting unit result in products with large dimensions. If necessary, the cutting disc must be guided along a path to perform the desired cut in the required length.
Mit steigender Präzision bei der Bearbeitung eines Produkts steigt üblicherweise auch die Bearbeitungszeit. Da beim Schneiden von Nahrungsmitteln die Durchsatzrate Vorgang hat, verzichtet der Produzent üblicherweise auf einen idealen Schnittverlauf. Dafür wird das Schnittgut vor dem Abpacken gegebenenfalls gewogen.With increasing precision when processing a product usually also increases the processing time. Since the throughput rate has process during the cutting of food, the producer usually dispenses with an ideal cutting process. For this purpose, the clippings are optionally weighed prior to packaging.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein verbessertes Verfahren und eine verbesserte Vorrichtung zum Schneiden von Nahrungsmitteln zu schaffen.It is therefore an object of the present invention to provide an improved method and apparatus for cutting food.
Insbesondere sind ein verbessertes Verfahren und eine Schneidvorrichtung anzugeben, bei denen dünne Scheiben von Nahrungsmitteln mit hoher Präzision und hohen Taktraten abgeschnitten werden können.In particular, an improved method and a cutting device are to be specified, in which thin slices of foods with high precision and high clock rates can be cut off.
Die geschnittenen Nahrungsmittelscheiben sollen ebene Schnittflächen und gleichmässige Dicken aufweisen. Die Präzision soll dabei auch dann erhalten bleiben, wenn die Festigkeitseigenschaften des zugeführten Nahrungsmittels oder parallel zugeführter Nahrungsmitteleinheiten ändert.The sliced food slices should have flat cut surfaces and uniform thicknesses. The precision should be maintained even when the strength properties of the supplied food or parallel feed units changed.
Die Schneidvorrichtung soll einfach aufgebaut sein und mit geringem Aufwand gewartet werden können.The cutting device should be simple and can be maintained with little effort.
Diese Aufgabe wird mit einem Verfahren und einer Vorrichtung gelöst, welche die in Anspruch 1 bzw. Anspruch 8 angegebenen Merkmale aufweisen. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved by a method and a device which are as defined in
Das Verfahren und die Vorrichtung dienen dem Schneiden eines Nahrungsmittels, welches als Einheit oder parallel in mehreren vorzugsweise stangenförmigen Nahrungsmitteleinheiten zugeführt wird. Die Schneidvorrichtung umfasst eine Schneideeinheit mit wenigstens einem Schneidwerkzeug, eine Schubeinheit mit wenigstens einem Schubwerkzeug, wenigstens eine Antriebsvorrichtung für den Antrieb des Schneidwerkzeugs und des Schubwerkzeugs, und einen Fördertisch, auf dem das Nahrungsmittel abgelegt und mittels des Schubwerkzeugs zum Schneidwerkzeug hin gestossen wird.The method and apparatus are for cutting a food which is supplied as a unit or in parallel in a plurality of preferably bar-shaped food units. The cutting device comprises a cutting unit with at least one cutting tool, a pushing unit with at least one pushing tool, at least one driving device for driving the cutting tool and the pushing tool, and a conveying table on which the food is deposited and pushed by the pushing tool towards the cutting tool.
Erfindungsgemäss wird die Antriebsvorrichtung in einem Arbeitszyklus derart gesteuert, dass das Schubwerkzeug in einem ersten Zyklusabschnitt das Nahrungsmittel an der Rückseite erfasst und hin zum Schneidwerkzeug stösst und vom Nahrungsmittel wieder gelöst und zurückgezogen wird, wonach in einem zweiten Zyklusabschnitt das Schneidwerkzeug gegen das Nahrungsmittel geführt und an der Frontseite des Nahrungsmittels eine Nahrungsmittelscheibe abgeschnitten wird.According to the invention, the drive device is controlled in a work cycle such that the pusher tool in a first cycle section detects the food on the back and pushes towards the cutting tool and is released from the food and withdrawn, after which in a second cycle section the cutting tool is guided against the food and on the front of the food is cut off a food slice.
Vor der Durchführung des Schneidevorgangs wird das Nahrungsmittel somit gegen das Schneidwerkzeug gefördert und vom Schubwerkzeug entlastet. Bei der Durchführung des Schneidevorgangs, während dessen eine Klinge durch das Nahrungsmittel geführt wird, wirken daher keine Schubkräfte auf das Nahrungsmittel und die Klinge ein. Die Klinge wird nur mit Kräften beaufschlagt, die parallel dazu verlaufen, weshalb der Schnitt mit maximaler Präzision ausgeführt werden kann. Da das Nahrungsmittel ebenfalls nur mit Kräften beaufschlagt ist, die senkrecht dazu verlaufen, werden Deformationen des Nahrungsmittels vermieden und ebene Schnittflächen erzielt. Besonders vorteilhaft und präzise können die Schnitte mit einem Schneidwerkzeug mit einer Klinge ausgeführt werden, dem zumindest während des Schneidevorgangs Ultraschallenergie zugeführt wird. Die Schneideeinheit umfasst vorzugsweise eine Lagervorrichtung, mittels der wenigstens ein Ultraschallgenerator vertikal verschiebbar gehalten ist, der über ein Kopplungselement mit einer Klinge verbunden ist.Before carrying out the cutting process, the food is thus conveyed against the cutting tool and relieved by the pushing tool. Therefore, when performing the cutting operation during which a blade is passed through the food, no pushing forces are applied to the food and the blade. The blade is loaded only with forces that run parallel to it, which is why the cut can be performed with maximum precision. Since the food is also loaded only with forces that are perpendicular to it, deformations of the food are avoided and achieved flat cut surfaces. Particularly advantageously and precisely, the cuts can be carried out with a cutting tool with a blade which is supplied with ultrasonic energy at least during the cutting process. The cutting unit preferably comprises a bearing device, by means of which at least one ultrasonic generator is held vertically displaceably, which is connected via a coupling element with a blade.
In einer vorzugsweisen Ausgestaltung wird die Klinge somit vom Ultraschallgenerator gehalten. Vorzugsweise ist auf dem Klingenrücken oder einer daran angeformten Extremität eine Montagefläche vorgesehen, auf der ein erstes Endstück eines in einem Bogen verlaufenden, vorzugsweise U-förmigen Kopplungselements angeschweisst ist, dessen zweites Endstück ein Verbindungselement, vorzugsweise eine Gewindebohrung, aufweist, welches mit dem Ultraschallgenerator lösbar verbunden ist.In a preferred embodiment, the blade is thus held by the ultrasonic generator. Preferably, a mounting surface is provided on the back of the blade or an extremity formed thereon, on which a first end piece of an arcuate, preferably U-shaped coupling element is welded, the second end piece has a connecting element, preferably a threaded bore, which is detachable with the ultrasonic generator connected is.
Das Kopplungselement ist beispielsweise ein gebogener Stab mit einem Rundprofil oder einem Mehrkantprofil, der mit dem ersten Endstück vorzugsweise senkrecht zum Klingenrücken und somit senkrecht zur Schnittrichtung und parallel zur Transportrichtung des Nahrungsmittels ausgerichtet ist.The coupling element is for example a bent rod with a round profile or a polygonal profile, which is aligned with the first end piece preferably perpendicular to the blade back and thus perpendicular to the cutting direction and parallel to the transport direction of the food.
Mit dieser Schneidevorrichtung kann das Nahrungsmittel praktisch ohne Kraftaufwand geschnitten werden. Während des Schneidevorgangs wirken daher kaum Kräfte auf das Nahrungsmittel ein, weshalb eine maximale Präzision bei der Durchführung des Schnittvorganges erzielt wird.With this cutting device, the food can be cut with virtually no effort. During the cutting process, therefore, hardly any forces act on the food, which is why maximum precision is achieved in performing the cutting process.
In einer vorzugsweisen Ausgestaltung ist das Nahrungsmittel auf einem Auflagebereich eines elastischen Elements ganz oder teilweise gelagert, welches während des Vorschubs des Nahrungsmittels im Auflagebereich gestaucht wird und sich nach dem Lösen des Schubwerkzeugs im Auflagebereich dehnt. Das elastische Element erfährt während des Fördervorgangs eine ähnliche Krafteinwirkung wie das Nahrungsmittel. D.h., das Nahrungsmittel und der betreffende Abschnitt des elastischen Elements im Auflagebereich des Nahrungsmittels werden während des Vorschubs unter Einwirkung des Schubwerkzeugs gestaucht. Nach dem Rückziehen des Schubwerkzeugs kann das Nahrungsmittel relaxieren. Die Relaxation des Nahrungsmittels wird durch das elastische Element, welche sich ebenfalls ausdehnt, aktiv unterstützt. Nach dem Rückziehen des Schubwerkzeugs erfolgt vor Durchführung des Schneidevorgangs ein rascher Abbau der Kräfte innerhalb des Nahrungsmittels und somit ein Abbau der Deformation des Nahrungsmittels.In a preferred embodiment, the foodstuff is wholly or partly stored on a support region of an elastic element, which is compressed during the advancement of the food in the support area and stretches after releasing the pushing tool in the support area. The elastic element undergoes during the delivery process a similar force as the food. That is, the food and the respective portion of the elastic element in the contact area of the food are compressed during the feed under the action of the pushing tool. After retraction of the pusher, the food can relax. The relaxation of the food is actively supported by the elastic element, which also expands. After retraction of the pushing tool, a rapid reduction of the forces within the food and thus a reduction of the deformation of the food takes place before carrying out the cutting process.
In einer vorzugsweisen Ausgestaltung weist der ein- oder mehrteilige Fördertisch mehrere parallel zueinander ausgerichtete Förderkanäle auf, in denen je wenigstens ein elastisches Element angeordnet ist und in denen zylinderförmige oder stangenförmige Teile des Nahrungsmittels gefördert werden können.In a preferred embodiment, the single or multi-part conveyor table on several parallel aligned conveying channels, in each of which at least one elastic element is arranged and in which cylindrical or rod-shaped parts of the food can be promoted.
Das elastische Element ist beispielsweise eine auf dem Fördertisch abgelegte elastische Lagerplatte. Sofern Förderkanäle vorgesehen sind, ist in jedem Förderkanal wenigstens ein seilförmiges, schnurförmiges oder riemenförmiges elastisches Element angeordnet.The elastic element is for example a stored on the conveyor table elastic bearing plate. If delivery channels are provided, at least one rope-shaped, cord-shaped or belt-shaped elastic element is arranged in each delivery channel.
Vorzugsweise verlaufen in jedem der Förderkanäle zwei schnurförmige oder riemenförmige elastische Elemente parallel zueinander, deren Enden im Eingangsbereich und im Ausgangsbereich des zugehörigen Förderkanals gehalten und gegebenenfalls miteinander verbunden sind. Die elastischen Elemente sind vorzugsweise symmetrisch in jedem Förderkanal angeordnet, so dass das Nahrungsmittel auf beiden Seiten gleichmässig gestützt wird.Preferably, in each of the conveyor channels, two string-shaped or belt-shaped elastic elements extend parallel to each other, the ends of which are held in the input area and in the outlet area of the associated conveyor channel and possibly interconnected. The elastic elements are preferably arranged symmetrically in each conveying channel, so that the food is supported evenly on both sides.
Vorzugsweise werden elastische Elemente verwendet, die aus Elastomeren, vorzugsweise Fluorelastomeren, bestehen.Preferably, elastic elements are used which consist of elastomers, preferably fluoroelastomers.
Im Bereich des Schneidwerkzeugs ist vorzugsweise ein Niederhalter vorgesehen, der einen drehbar und elastisch gehaltenen Stab aufweist, an dem vorzugsweise für jeden der Förderkanäle eine vorzugsweise elastische Niederhalteplatte befestigt ist. Mittels des Niederhalters wird das Nahrungsmittel fixiert, ohne dass es komprimiert oder deformiert wird.In the region of the cutting tool, a hold-down device is preferably provided, which has a rotatably and elastically held rod, to which a preferably elastic hold-down plate is preferably fastened for each of the conveying channels. By means of the hold-down the food is fixed without being compressed or deformed.
Mittels der erfindungsgemässen Vorrichtung können beliebige Nahrungsmittel, wie Fleischwaren, Käse, Gemüse, oder Brot, in feinen Nahrungsmittelscheiben mit hoher Präzision geschnitten werden. Aufgrund der hohen Präzision kann in der Folge darauf verzichtet werden, das geschnittene Nahrungsmittel zu wägen. Stattdessen können die Nahrungsmittelscheiben gezählt und in der gewünschten Anzahl verpackt werden.By means of the device according to the invention, any foods, such as meat products, cheese, vegetables, or bread, can be cut in fine food slices with high precision. Due to the high precision can be waived in the sequence subsequently to cut the food. Instead, the food slices can be counted and packaged in the desired number.

Das Nahrungsmittel 8 wird den vier Schneidwerkzeugen 11A, ..., 11D in zwölf zylinderförmigen oder stangenförmigen Einheiten 8A, ..., 8L parallel zugeführt, so dass jeweils drei der Nahrungsmitteleinheiten 8A, ..., 8L von einem der Schneidwerkzeuge 11A; ...; 11D gleichzeitig geschnitten werden. Frontseitig sind die parallel zugeführten Nahrungsmitteleinheiten 8A, ..., 8L von einem Niederhalter 4 in einer gewünschten Position gehalten, während der Schnitt ausgeführt wird.The food 8 is fed in parallel to the four
Die Schneideeinheit 1 umfasst die vier Schneidwerkzeuge 11A; ...; 11D (siehe auch
Ferner ist eine Steuereinheit 6 vorgesehen, welche die Schneideeinheit 1, die Schubeinheit 2, die Ultraschallgeneratoren 13 und den Abnahmeförderer 9 steuern kann. Die Steuereinheit 6 ist über eine erste Steuerleitung 61 mit der Schneideeinheit 1, eine zweite Steuerleitung 62 mit der Schubeinheit 22, eine dritte Steuerleitung 63 mit den Ultraschallgeneratoren 13 und eine vierte Steuerleitung 69 mit dem Abnahmeförderer 9 verbunden. Der Steuereinheit 6 sind über eine Tastatur 60 und von Messgeräten 68, wie Messungsformern und Sensoren, Informationen zuführbar, mittels denen der Schneideprozess und der Förderprozess gesteuert werden können. Mittels ersten Sensoren 68 werden beispielsweise Informationen zu den Positionen der Nahrungsmitteleinheiten 8 ermittelt. Mittels zweiten Sensoren 67 können weitere Prozessgrössen ermittelt werden. Vorzugsweise werden die Temperatur und die Konsistenz der Nahrungsmittel gemessen und in Abhängigkeit davon die Ultraschallfrequenz, die Schnittgeschwindigkeit und die Schubgeschwindigkeit eingestellt. Zur Steuerung aller Prozesse, insbesondere der Schneidprozesse und Förderprozesse ist ein Anwendungsprogramm vorgesehen.Further, a control unit 6 is provided which can control the
Die Schneideprozesse und Förderprozesse verlaufen zyklisch und phasenverschoben in gemeinsamen Arbeitszyklen. In einem ersten Abschnitt eines Arbeitszyklus werden die 8A, ..., 8L vom Schubwerkzeug 21 an der Rückseite erfasst und gegen das Schneidwerkzeug 11 gestossen. Nachdem die gewünschte Verschiebung erreicht ist, die typischerweise der Dicke einer zu schneidenden Nahrungsmittelscheibe 81 entspricht, wird das Schubwerkzeug 21 von den Nahrungsmitteleinheiten 8A, ..., 8L wieder gelöst und zurückgezogen. Erst anschliessend, in einem zweiten Abschnitt des Arbeitszyklus werden die Schneidwerkzeuge 11A, ..., 11D senkrecht gegen die Nahrungsmitteleinheiten 8 geführt, wobei an der Frontseite jeder Nahrungsmitteleinheit 8A, ..., 8L eine Nahrungsmittelscheibe 81 abgeschnitten wird. Noch innerhalb des zweiten Abschnitts des Arbeitszyklus werden die Schneidwerkzeuge 11A, ..., 11D wieder vertikal nach oben geführt, so dass die Frontseiten der Nahrungsmitteleinheiten 8A, ..., 8L wieder frei liegen. Nach Abschluss des Arbeitszyklus werden die Nahrungsmitteleinheiten 8A, ..., 8L im nächsten Arbeitszyklus wieder sequenziell vom Schubwerkzeug 21 erfasst und von den Schneidwerkzeugen 11A, ..., 11D bearbeitet. Die Dauer der beiden Abschnitte des Arbeitszyklus wird vorzugsweise in Abhängigkeit der Beschaffenheit der Nahrungsmitteleinheiten 8A, ..., 8L gewählt. Während bei der Verarbeitung von Nahrungsmitteleinheiten 8A, ..., 8L mit höherer Festigkeit der Schubvorgang schneller durchgeführt wird und somit kürzere erste Zyklusabschnitte gewählt werden, erfolgt der Schneidevorgang vorzugsweise etwas langsamer, weshalb längere zweite Zyklusabschnitte gewählt werden. Nahrungsmitteleinheiten 8A, ..., 8L mit geringerer Festigkeit werden vorzugsweise langsamer gefördert und können dafür schneller geschnitten werden. Dieselben Nahrungsmitteleinheiten 8A, ..., 8L können bei höheren und tieferen Temperaturen unterschiedliche Festigkeiten aufweisen, weshalb die Länge der Zyklusabschnitte vorzugsweise unter Berücksichtigung der gemessenen Temperaturen gewählt wird. Ebenso wird die Frequenz der Ultraschallenergie vorzugsweise in Abhängigkeit der Beschaffenheit und der Temperatur der Nahrungsmitteleinheiten 8A, ..., 8L gewählt.The cutting processes and conveying processes run cyclically and out of phase in common working cycles. In a first portion of a working cycle, the 8A,..., 8L are grasped by the pushing
Aufgrund des Rückzugs der Schubwerkzeugs 21 nach Abschluss des Fördervorgangs können die Nahrungsmitteleinheiten 8A, ..., 8L relaxieren und ihre ursprüngliche Form wieder annehmen, weshalb Nahrungsmittelscheiben 81 präzise abgeschnitten werden können. Gleichzeitig wird verhindert, dass ein Druck vom Schubwerkzeug auf die Klingen der Schneidwerkzeuge 11A, ..., 11D ausgeübt wird.Due to the retraction of the pushing
Jede der stangenförmigen Nahrungsmitteleinheiten 8A, ..., 8L wird daher durch ein Paar von elastischen Elementen 34A, ..., 34L gestützt. Die Oberflächenbeschaffenheit und die Elastizität der elastischen Elemente 34A, ..., 34L sind dabei derart gewählt, dass der Abschnitt der elastischen Elemente 34A, ..., 34L im Auflagebereich der Nahrungsmitteleinheiten 8A, ..., 8L während des Vorschubs der Nahrungsmitteleinheiten 8A, ..., 8L gestaucht wird und sich nach dem Lösen des Schubwerkzeugs 21 im Auflagebereich dehnt.Each of the bar-shaped
Die Frontseiten der Nahrungsmitteleinheiten 8A, ..., 8L, die von Niederhalteplatten 43A, ..., 43L eines Niederhalters 4 gehalten werden, werden über die elastischen Elementen 34A, ..., 34L gestossen, während die elastischen Elemente 34A, ..., 34L zumindest anteilsweise soweit gestaucht werden, wie die Nahrungsmitteleinheiten 8A, ..., 8L komprimiert werden. Nach der Rückführung des Schubwerkzeugs 21, welches für jede der Nahrungsmitteleinheiten 8A, ..., 8L eine Schubplatte 21A, ..., 21L aufweist, erfolgt die erwähnte Entspannung der Nahrungsmitteleinheiten 8A, ..., 8L mit Unterstützung der elastischen Elemente 34A, ..., 34L, wodurch gleichzeitig eine allfällige Deformation an der Frontseite der Nahrungsmitteleinheiten 8A, ..., 8L aufgehoben wird. Aufgrund der Unterstützung dieses Vorgangs durch die elastischen Elemente 34A, ..., 34L erfolgt die Relaxation in sehr kurzer Zeit.The front sides of the
Während des Fördervorgangs passen sich die elastischen Elemente 34A, ..., 34L an die gelagerten Nahrungsmitteleinheiten 8A, ..., 8L an, weshalb auch Unterschiede zwischen den Nahrungsmitteleinheiten 8A, ..., 8L automatisch ausgeglichen werden. Die elastischen Elemente 34A, ..., 34L denen sich daher unterschiedlich, falls die einzelnen Nahrungsmitteleinheiten 8A, ..., 8L unterschiedliche Festlichkeiten aufweisen.During the conveying operation, the
Die Unterstützung bei der Förderung, Positionierung und Relaxation der Nahrungsmitteleinheiten 8A, ..., 8L erfolgt somit mit einfachen Massnahmen, weshalb auf komplexe Messvorrichtungen und Steuervorrichtungen verzichtet werden kann, welche alternativ eingesetzt werden könnten, um eine erhöhte Genauigkeit des Schneidevorganges zu erzielen. Erfindungsgemäss kann die hohe Präzision daher mit der präzise arbeitenden Schubeinheit 2 und der erfindungsgemässen Schneidvorrichtung 1 erzielt werden.The support in the promotion, positioning and relaxation of the

Die Schneidewerkzeuge 11A, ..., 11D umfassen je eine Klinge, an deren Rücken die in einem Bogen verlaufenden Kopplungselemente 15 angeschweisst sind, wodurch die Ultraschallenergie vorteilhaft in die Klingen ein gekoppelt werden kann.The
Mit diesen Schneidewerkzeugen 11A, ..., 11D können die Nahrungsmitteleinheiten 8A, ..., 8L praktisch ohne Kraftaufwand geschnitten werden. Während des Schneidevorgangs wirken daher praktisch keine Kräfte auf das Nahrungsmittel ein, weshalb eine maximale Präzision erzielt wird.With these
