Abstract

The vegetable (G), which can be a carrot or a stalk of celery, is moved by a pushing element (7) along a guide with a v-shaped cross section (9) to a cutting blade (10) for the removal of a front segment. The position is detected by a sensor. When the sensor recognizes the rear end of the vegetable another cut is made. The item (G) is pushed into a tube (20) moving from a horizontal into a vertical position in order to guide the vegetable (G) to the cutting unit (30) creating star-, shamrock-, heart- or other attractively shaped slices.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Schneiden von länglichen, vorzugsweise wurzelgemüsen, insbesondere Karotten in Scheiben mit dekorativer Formgebung, mit mindestens einem Ketten- oder Bandfördervorrichtung, die das Gemüse von einer Eingabeseite zu einer ersten Station, in der das Gemüse beidseitig an den Enden abgeschnitten wird und zu einer zweiten Station mit formgebenden Schneidmatrize gelangt und in einer anschliessenden Station mit ein- oder mehrschneidigen, rotierenden Schneidscheibe in Scheiben geschnitten wird.The present invention relates to a device for cutting elongated, preferably root vegetables, in particular carrots in decorative ornamental discs, with at least one chain or belt conveyor device which cuts the vegetables from an input side to a first station where the vegetables are cut off at both ends is and reaches a second station with forming cutting die and sliced in a subsequent station with single or multi-bladed rotating cutting disc.

Gemüse wird zu verschiedensten Zwecken zu dekorativen Formen zurechtgeschnitten und anschliessend in Scheiben geschnitten. Beispielsweise werden so Karotten, Sellerie, Rettich oder auch Kartoffeln zugeschnitten. Anschliessend werden diese Scheiben beispielsweise einem Salat beigefügt oder auf Fleischplatten zur Dekoration hingelegt oder schliesslich auch frittiert um schliesslich ein dekoratives fertiges Produkt zu erhalten. In Haushalten wird dies meist von Hand erledigt, wobei auf dem Markt entsprechende Ausstecher oder Spezialmesser erhältlich sind. Aus der DE-A-102 36 357 ist eine einfache Handvorrichtung bekannt, die aus einem Rohr besteht mit einer einseitig angeordneten Schneidmatrize und einer Vielzahl von quer zur Längsrichtung verlaufenden Schlitze durch die mittels einem Messer die länglich zugeschnittenen Gemüseteile quer geschnitten werden können um so schliesslich entsprechend geformte Scheiben oder Würfel zu erhalten. Eine solche Vorrichtung ist für Haushalte sowie kleinere Gastronomiebetriebe geeignet.Vegetables are cut into decorative shapes for various purposes and then sliced. For example, carrots, celery, radish or even potatoes are cut to size. These slices are then added, for example, to a salad or put on meat plates for decoration or finally deep-fried to finally obtain a decorative finished product. In homes, this is usually done by hand, with the market corresponding cookie cutters or special knives are available. From the DE-A-102 36 357 is a simple hand device is known which consists of a tube with a cutting die arranged on one side and a plurality of slots extending transversely to the longitudinal direction through which the oblong cut vegetable parts can be cut transversely by means of a knife so as finally to obtain correspondingly shaped discs or cubes. Such a device is suitable for households and smaller catering establishments.

Für die hier interessierende industrielle Fertigung sind verschiedene Lösungen bekannt. Hierbei hat es sich herausgestellt, dass eines der wesentlichsten Probleme darin besteht, das zuzuschneidende Gemüse möglichst exakt ausgerichtet auf die Formgebende Matrize zuzuführen. Eine Lösung für dieses Problem zeigt beispielsweise die US-A 3,974,725 . In dieser Vorrichtung wird das Gemüse mittels drei synchronlaufenden Vorschubbändern realisiert. Ein erstes Band bildet die Auflagefläche während zwei zur Zuschneidstation hin konisch zusammenlaufende Bänder vertikal angeordnet sind und so einen konischen Kanal zusammen mit dem Trägerband der Auflagefläche bildet. Da Gemüse eine ausserordentlich unregelmässige Form aufweist und insbesondere auch eine Konizität haben kann, führt dies dazu, dass das Gemüse bezüglich deren Längsachse am Ende der Einlaufstrecke keineswegs exakt ausgerichtet ist. Während der erste senkrecht zur Längsrichtung des Gemüses anzubringende Schnitt nicht unbedingt äusserst exakt senkrecht verlaufen muss, ist dies jedoch beim zweiten Schnitt eher heikel. Denn diese Schnittfläche wird anschliessend benötigt, um das Gemüse vorwärts zu schieben auf eine Schneidmatrize zu. Ist diese Schnittfläche nicht senkrecht sondern geneigt, so wird entsprechend das Gemüse nicht gerade auf die Schneidmatrize zugeführt und das zu schneidende dekorative Muster wird nur teilweise erzielt und entsprechend müssen solche nicht korrekt geschnittene Gemüse aussortiert werden. Dies erzeugt einen erheblichen Ausschussanteil.Various solutions are known for the industrial production of interest here. It has been found that one of the most important problems is to feed the vegetables to be cut as exactly as possible aligned with the forming die. One solution to this problem is shown by the example US-A 3,974,725 , In this device, the vegetables are realized by means of three synchronous feed belts. A first band forms the support surface while two bands converging conically towards the cutting station are arranged vertically, thus forming a conical channel together with the carrier band of the support surface. Since vegetables have an extraordinarily irregular shape and in particular may also have a conicity, this leads to the fact that the vegetables with respect to their longitudinal axis at the end of the inlet line is by no means exactly aligned. While the first perpendicular to the longitudinal direction of the vegetable to be attached cut does not necessarily run extremely precisely vertically must, but this is rather tricky in the second cut. Because this cutting surface is then needed to push the vegetables forward on a cutting die. If this cut surface is not vertical but inclined, then the vegetable is not fed straight to the cutting die and the decorative pattern to be cut is only partially achieved and accordingly such incorrectly cut vegetables must be sorted out. This generates a considerable amount of rejects.

Das Wissen um diese Problematik führt dazu, dass beispielsweise für Karotten besondere Züchtungen vorhanden sind, die kaum konisch sind, sondern eine mindestens annähernd zylindrische Form über einen grossen Teil ihrer Länge aufweisen. Auch bei diesen Züchtungen ist jedoch eine gewisse Konizität immer noch vorhanden und zusätzlich varieren die Karotten im Durchmesser und ein gewisser Anteil konischer Rüben ist immer noch vorhanden. Entsprechend ist der Ausschussanteil trotz der Verwendung von Rüben dieser speziellen Zucht immer noch über 10 %. Diese Problematik ist schon seit langem bekannt und entsprechend geht aus der GB-A-2 315 991 eine verbesserte Variante hervor, bei dem das Gemüse in halbzylindrischen Schalen auf die Schneidmatrize zugeschoben werden. Im Wissen um das Problem der Konizität der Karotten wird hier zusätzlich die Möglichkeit offenbart, diese halbzylindrischen Zuführungsschalen selber konisch zulaufend zu gestalten. Dies gibt aber keine vernünftige Lösung. Wie bereits erwähnt, kann die Form des zuzuschneidenden Gemüses von kegelförmig bis zylindrisch beliebig varieren, der Durchmesser abweichend sein und auch die Rundheit zu wünschen übrig lassen. Eine Anpassung dieser Zuführung an die Form des zuzuschneidenden Gemüses erfolgt nicht. Entsprechend ist auch bei einer Vorrichtung der hier offenbarten Ausgestaltung mit einem erheblichen Ausschussanteil zu rechnen.The knowledge of this problem means that, for example, for carrots special varieties are present, which are hardly conical, but have an at least approximately cylindrical shape over a large part of their length. However, even with these varieties a certain conicity is still present and in addition the carrots vary in diameter and a certain proportion of conical beets is still present. Accordingly, despite the use of beets from this particular breed, the reject rate is still over 10%. This problem has long been known and accordingly goes from the GB-A-2 315 991 an improved variant in which the vegetables are pushed in semi-cylindrical shells on the cutting die. In the knowledge of the problem of the conicity of the carrots is additionally disclosed here the possibility of making these semi-cylindrical feed trays themselves tapered. But this is not a sensible one Solution. As already mentioned, the shape of the vegetables to be cut can vary from conical to cylindrical, the diameter may differ and also the roundness leaves something to be desired. An adaptation of this feed to the shape of zuzuschneidenden vegetables is not. Accordingly, even with a device of the embodiment disclosed here, a considerable amount of rejects can be expected.

Schliesslich ist auf dem Markt eine Vorrichtung gemäss Oberbegriff des Patentanspruches 1 bekannt, bei der eingabeseitig das Gemüse durch eine relativ kurze Zuführungsstrecke durchgeführt wird, in der Kunststofflappen von mehreren Seiten her das Gemüse elastisch führen, um es zentrisch auszurichten. Diese Lösung hat sich aber keineswegs bewährt. Die Führung innerhalb der Durchführungsstrecke ist relativ kurz und bei der Durchführung des zweiten Schnittes hängt das Gemüse klemmend zwischen diesen Kunststofflappen doch neigt das Gemüse unter Einfluss der Schwerkraft mehr oder weniger stark nach unten, so dass dieser zweite Schnitt praktisch konstant mehr oder weniger stark geneigt verläuft. Ist der Durchmesser geringer, so ist entsprechend auch die Haltekraft geringer, ist der Durchmesser des zuzuschneidenden Gemüses grösser so neigt das Gemüse dazu sich in der Durchführungsstrecke zu verklemmen. Entsprechend darf die Variation des zuzuschneidenden Gemüses nicht zu stark abweichen und muss folglich bereits vorsortiert werden.Finally, in the market, a device according to the preamble of claim 1 is known, in the input side, the vegetables is performed by a relatively short feed path, in the plastic cloth from several sides lead the vegetables elastic to align it centric. This solution has by no means proven itself. The leadership within the implementation route is relatively short and in the implementation of the second cut the vegetables hanging between these plastic cloths but the vegetables tend under gravity more or less down, so that this second cut is practically constant more or less inclined , If the diameter is smaller, then the holding force is correspondingly lower, the diameter of the zuzuschneidenden vegetables is greater so tends the vegetables to jam in the implementation route. Accordingly, the variation of the zuzuschneidenden vegetables must not deviate too much and therefore must be pre-sorted.

Es ist folglich die Aufgabe der vorliegenden Erfindung eine Vorrichtung der eingangs genannten Art zu schaffen, die eine möglichst exakt zentrierte Zuführung des Gemüses zur Schneideschablone sicherstellt und entsprechend den Ausschussanteil vermindert. Diese für den Gemüseverarbeiter ökonomisch äusserst wesentliche Aufgabe löst eine Vorrichtung mit den Merkmalen des Patentanspruches 1.It is therefore an object of the present invention to provide a device of the type mentioned above, which ensures the most accurate possible centered feeding the vegetables to the cutting template and reduces the proportion of rejects accordingly. This economically essential for the vegetable processor solves a device having the features of claim 1.

Im Zuführungstisch 5 ist eine Ketten- oder Bandfördervorrichtung integriert angeordnet. Die Ketten- oder Bandfördervorrichtung kann eine beliebige Länge aufweisen an der eine oder mehrere Bedienungspersonen stehen können um das zuzuschneidende Gemüse lagekorrekt auf die Ketten- oder Bandfördervorrichtung aufzulegen. Die Ketten- oder Bandfördervorrichtung. 6 ist mit mehreren Mitnehmer 7 versehen, die das aufgelegte Gemüse zu einer Schneidvorrichtung 10 vorschieben. Rein symbolisch ist mit 8 der Antrieb der Fördervorrichtung angedeutet.The entire device is designated overall by 1. It comprises a frame 2 with feed side legs 3 and two guide columns 4, which together carry a feed table 5. In feeder table 5 a chain or belt conveyor is arranged integrated. The chain or belt conveyor may be of any length the one or more operators can stand on the vegetables to be cut correct position on the chain or belt conveyor. The chain or belt conveyor. 6 is provided with a plurality of carriers 7, which advance the laid vegetables to a cutting device 10. Purely symbolically indicated by 8 of the drive of the conveyor.

Das zu schneidende Gemüse ist lediglich symbolisch dargestellt und mit G bezeichnet. Das Gemüse variiert im Durchmesser, in der Länge und in der Form. Bei der erfindungsgemässen Vorrichtung spielt dies jedoch eine untergeordnete Rolle. Die Mitnehmer 7 schieben das Gemüse auf dem Zuführungstisch 5 vor, wobei entsprechende Führungsmittel vorhanden sind, beispielsweise längs verlaufende Stege, die quer zur Verschieberichtung ein V-Provil definieren und so das Gemüse in einer Prismaführung 9 in eine korrekte Längsausrichtung zur Schneidevorrichtung 10 führt. Die Schneidvorrichtung ist mit einer hier nicht dargestellten Sensorüberwachung ausgerüstet, die den Anfang eines Gemüses erkennt und in einem vorgebbaren Abstand von diesem Anfang eine Frontscheibe abschneidet. Bei den Karotten, Rüben oder Rettich entspricht dies normalerweise der Krautseite. Der Sensor schaltet einen entsprechenden Ablauf der darin besteht, dass die Förderkette beziehungsweise das Förderband angehalten wird und ein Schneidmesser 11 über eine Antriebsäule 12 betätigt wird. Die Antriebsäule 12 kann einen hydraulischen oder elektromechanischen Antrieb enthalten. Das abgeschnittene Teil kann entweder unter Schwerkraft Einfluss am Ende des Förderbandes auf eine Rutsche fallen oder mittels einem hier ebenfalls nicht dargestellten Schieber aus dem Schnittbereich befördert werden. Danach wird das Gemüse weiter vorbewegt, bis die Sensoren entweder das Ende des Gemüses oder einen mindest Querschnitt des Gemüses feststellen, worauf die Überwachungssensoren wiederum denselben Schneidzyklus auslösen.The vegetables to be cut are only shown symbolically and marked G. The vegetables vary in diameter, length and shape. In the device according to the invention, however, this plays a subordinate role. The drivers 7 advance the vegetables on the feed table 5, with corresponding guide means being provided, for example longitudinal webs which define a V-Provil transverse to the direction of displacement and thus guide the vegetables in a prism guide 9 in a correct longitudinal orientation to the cutting device 10. The cutting device is equipped with a sensor monitoring, not shown here, which detects the beginning of a vegetable and cuts off at a predeterminable distance from this beginning a windscreen. For carrots, turnips or radishes this is usually the herb side. The sensor switches a corresponding sequence which consists in that the conveyor chain or the conveyor belt is stopped and a cutting blade 11 is actuated via a drive column 12. The drive column 12 may have a hydraulic or electromechanical drive included. The cut part can either fall under gravity influence at the end of the conveyor belt on a chute or be transported by means of a slide also not shown here from the cutting area. Thereafter, the vegetables are advanced further until the sensors detect either the end of the vegetables or a minimum section of the vegetables, whereupon the monitoring sensors in turn trigger the same cutting cycle.

Anschliessend schiebt der Mitnehmer 7 von der Ketten- oder Bandfördervorrichtung 6 getrieben das Gemüse in einer fluchtend mit der entsprechenden Prismaführung ausgerichteten Zentrierrohr 20. Bezüglich der genaueren Ausgestaltung des Zentrierrohres, welches das Herzstück der vorliegenden Erfindung betrifft, wird auf die später folgende Beschreibung der Figur 2 verwiesen in der das Zentrierrohr detailliert dargestellt ist. Sobald das Gemüse im Zentrierrohr 20 eingeschoben und das Ende gerade geschnitten ist, schwenkt dieses von seiner horizontalen Lage in eine vertikale Lage, die hier mit 20' bezeichnet ist. In der geschwenkten Lage 20' ist das Zentrierrohr 20 exakt ausgerichtet, senkrecht über einer Schneidmatrize 30 ausgerichtet gehalten. In dieser Position ist auch ein Transportmittel 40 exakt über das geschwenkte Zentrierrohr 20' angeordnet. Dieses Transportmittel 40 besteht aus einem Stössel 41, der mittels einer Kolbenzylindereinheit 42 beziehungsweise einem Elektromotor mit einer Förderspindel auf und ab bewegbar ist. Die Kolbenzylindereinheit 42 beziehungsweise der Elektromotor mit Spindel ist oberhalb eines Querträgers 4', der die beiden Führungssäulen 4 verbindet, gehalten. Der Stössel 41 senkt sich von der Kolbenzylindereinheit 42 getrieben in das Zentrierrohr 20' und stösst das darin gelagerte Gemüse nach unten durch die Schneidmatrize 30 hindurch.Subsequently, the driver 7 driven by the chain or belt conveyor 6 pushes the vegetables in a centering tube 20 aligned with the corresponding prism guide. With regard to the more specific embodiment of the centering tube, which concerns the heart of the present invention, reference is made to the description of FIG referenced in the centering tube is shown in detail. Once the vegetables are inserted in the centering tube 20 and the end is cut straight, this pivots from its horizontal position in a vertical position, which is here designated 20 '. In the pivoted position 20 ', the centering tube 20 is aligned exactly, held vertically aligned above a cutting die 30. In this position, a transport means 40 is arranged exactly above the pivoted centering tube 20 '. This transport means 40 consists of a plunger 41, by means of a piston-cylinder unit 42 and a Electric motor with a feed spindle is movable up and down. The piston-cylinder unit 42 or the electric motor with spindle is above a cross member 4 ', which connects the two guide columns 4, held. The plunger 41, driven by the piston-cylinder unit 42, descends into the centering tube 20 'and pushes the vegetables stored therein downwards through the cutting die 30.

Bezüglich der Ausgestaltung der Schneidmatrize 30 wird auf die Beschreibung der Figuren 3 und 4 verwiesen. Die Schneidmatrize 30 ist in einer schienenförmigen Halterung 50 auswechselbar gehalten. Anschliessend an der Schneidmatrize 30 folgt ein Führungsrohr 60. Das Führungsrohr 60 ist so ausgelegt, dass lediglich das mit der dekorativen Formgestaltung zugeschnittene Gemüseteil in dieses Führungsrohr gelangt, während die äusseren Bereiche, das heisst die weggeschnittenen Gemüseteile, aussen am Führungsrohr 60 entlang gleiten und auf eine Rutsche 61 gelangen. Diese Rutsche 61 wird vom Führungsrohr 60 durchsetzt. Das Führungsrohr 60 endet kurz oberhalb einer rotierenden Schneidscheibe 70. Die Schneidscheibe 70 kann ein oder mehrere Schneiden 71 aufweisen, je nach der erforderlichen Arbeitsgeschwindigkeit und der Dicke der abzuschneidenden Scheiben. Entsprechend kann die Schneidscheibe 70 auswechselbar sein oder mit verstellbaren Schneiden 71 versehen sein. Solche Schneiden mit verstellbaren Schneidklingen sind auch für diese Anwendung bereits bekannt. Die Schneidscheibe 70 ist auf einer Antriebswelle 72 gelagert die über einen Riemen 73 von einem Elektromotor 74 angetrieben ist. Mit S sind die zugeschnittenen Gemüsescheiben gekennzeichnet. Diese fallen in ein hier nicht dargestellten Auffangbehältnis.With regard to the configuration of the cutting die 30, reference is made to the description of Figures 3 and 4. The cutting die 30 is held interchangeable in a rail-shaped holder 50. Subsequently, the cutting die 30 is followed by a guide tube 60. The guide tube 60 is designed so that only the vegetable part cut to the decorative shape passes into this guide tube, while the outer regions, ie the cut vegetable parts, slide outside on the guide tube 60 and on a chute 61 arrive. This chute 61 is penetrated by the guide tube 60. The guide tube 60 ends shortly above a rotating cutting disc 70. The cutting disc 70 may have one or more cutting edges 71, depending on the required operating speed and the thickness of the slices to be cut off. Accordingly, the cutting disc 70 can be exchangeable or be provided with adjustable cutting 71. Such cutting with adjustable cutting blades are also for this application already known. The cutting disc 70 is mounted on a drive shaft 72 which is driven via a belt 73 by an electric motor 74. S denotes the cut vegetable slices. These fall into a collection container, not shown here.

Aus der Figur 5 ersieht man, dass völlig unproblematisch zwei Arbeitslinien parallel geführt werden können. Hierzu wird lediglich ein entsprechendes Gestell benötigt und beide Führungsrohre 60 führen auf eine einzige Schneidscheibe 70. Hingegen müssen zwei unabhängig voneinander arbeitende Ketten- oder Bandfördervorrichtungen vorhanden sein, ebenso wie zwei Prismen, zwei Zentrierrohre, zwei Schneidmatrizen 30, und ebenso muss die entsprechende Sensorik für jede Arbeitslinie separat vorhanden sein. Dies liegt daran, dass das Gemüse sehr unterschiedlich ist und somit die beiden Arbeitslinien bezüglich der schrittweisen Fortbewegung völlig unabhängig voneinander arbeiten.From Figure 5 it can be seen that completely unproblematic two lines of work can be performed in parallel. For this purpose, only a corresponding frame is required and both guide tubes 60 lead to a single cutting disc 70. On the other hand, two independently working chain or belt conveyors must be present, as well as two prisms, two centering tubes, two cutting dies 30, and also the corresponding sensors for Each working line should be available separately. This is because the vegetables are very different and thus the two working lines with respect to the gradual locomotion work completely independently of each other.

In der Figur 2 ist das besonders erfindungswesentliche Zentrierrohr 20 perspektifisch im Detail dargestellt. Es umfasst das eigentliche Rohr 21, welches von mehreren Längsschlitzen 22, die parallel zur Längsachse verlaufen durchsetzt sind. Das eigentliche Rohr 21 hat eine Einführungsöffnung 23 und eine Austrittsöffnung 24. Die Längsschlitze 22 können offene Längsschlitze sein, die sich einerseits von der Einführungsöffnung 23 in Richtung zur Austrittsöffnung 24 erstrecken beziehungsweise in der Gegenrichtung von der Austrittsöffnung zur Einführungsöffnung hin verlaufend sind. In der hier dargestellten Ausführungsform sind die Längsschlitze 22 nicht bis in diese entsprechenden Öffnungen 23, 24 erstreckend, sondern als geschlossene Langlöcher ausgebildet. Diese Langlöcher sind über dem Umfang verteilt abwechslungsweise in Längsrichtung versetzt gestaltet. Gleichmässig über dem Umfang verteilt sind beispielsweise vier oder sechs gleichartig gelagerte Schlitze vorhanden während die versetzt verlaufenden Langlöcher um eine halbe Teilung der anderen Langlöcher angeordnet sind. Dies ergibt insgesamt acht oder zwölf gleichmässig über den Umfang verteilte Langlöcher.In FIG. 2, the centering tube 20, which is particularly important to the invention, is shown in detail in detail. It comprises the actual tube 21, which are penetrated by a plurality of longitudinal slots 22 which are parallel to the longitudinal axis. The actual tube 21 has an insertion opening 23 and an outlet opening 24. The longitudinal slots 22 may be open longitudinal slots, on the one hand from the insertion opening 23 in the direction of Exit or extend in the opposite direction from the outlet opening to the insertion opening 24. In the embodiment shown here, the longitudinal slots 22 are not extending into these corresponding openings 23, 24, but formed as closed slots. These slots are distributed over the circumference alternately designed offset in the longitudinal direction. Uniformly distributed over the circumference, for example, four or six identically mounted slots are present while the offset slots are arranged by half a pitch of the other slots. This results in a total of eight or twelve evenly distributed over the circumference slots.

Über das Zentrierrohr 20 sind hier zwei Halteringe 25 gestülpt. Diese Halteringe 25 dienen der Halterung von Federelementen 26 die verschieden ausgestaltet sein können. In jedem Fall sind die Federelemente 26 gewölbt gebogen. Mit ihrem gewölbten Teil ragen sie durch die Längsschlitze beziehungsweise den Langlöchern in das Innere des Zentrierrohres hinein. Die beiden Enden der Federelemente 26 liegen ausserhalb des Rohres 21 des Zentrierrohres 20. Somit ragt lediglich der gewölbt verlaufende Anteil der entsprechenden Federelemente 26 in das Rohr 21 hinein. Die Federelemente 26 sind in jedem Fall Biegefedern. Sie können aber entweder als Blattfedern gestaltet sein oder aber, wie hier dargestellt und besonders bevorzugt Torsionsfedern sein.About the centering tube 20 two retaining rings 25 are slipped here. These retaining rings 25 are used to hold spring elements 26 which can be configured differently. In any case, the spring elements 26 are bent arched. With their curved part they protrude through the longitudinal slots or slots into the interior of the centering tube. The two ends of the spring elements 26 are outside of the tube 21 of the centering tube 20. Thus, only the curved part of the corresponding spring elements 26 projects into the tube 21. The spring elements 26 are in each case bending springs. However, they can either be designed as leaf springs or, as shown here, and particularly preferably torsion springs.

Die Torsionsfedern haben ein oder mehrgängige Wickel 27 deren ein Ende vom Wickel 27 zu einer grossen Wölbung 28 geformt ist, während das andere Ende des Wickels ein gerade geformtes Halteende 29 bildet. Dieses gerade Ende ist in einer Bohrung 200 eingesteckt. Mittels einer Sicherungsschraube, die in einer radial verlaufenden Gewindebohrung steckt, wird die Torsionsfeder verdrehgesichert gehalten. Es sind jeweils Federelemente 26 an beiden Seiten des Halteringes 25 befestigt. Das gewölbte Ende 28 der Torsionsfeder kann dabei auch den benachbarten Haltering unterqueren.The torsion springs have one or more coils 27 whose one end from the coil 27 is formed into a large curvature 28, while the other end of the coil forms a straight shaped retaining end 29. This straight end is inserted in a bore 200. By means of a locking screw, which is inserted in a radially extending threaded hole, the torsion spring is held against rotation. There are each spring elements 26 attached to both sides of the retaining ring 25. The curved end 28 of the torsion spring can also pass under the adjacent retaining ring.

Neben der hier dargestellten und erläuterten Befestigungsform der Biegefeder kommen selbstverständlich auch andere Befestigungsarten in Frage. Beispielsweise können die Halteringe radial verlaufende Nuten 201 aufweisen, in denen der jeweilige Wickel 27 formschlüssig eingreifend gehalten ist. Dies ist rein beispielsweise dargestellt, doch wird durch diese Lösung die Torsionswirkung der Feder geringfügig reduziert.In addition to the illustrated here and explained form of attachment of the bending spring are of course other types of attachment in question. For example, the retaining rings may have radially extending grooves 201, in which the respective winding 27 is held positively engaging. This is shown purely as an example, but this solution slightly reduces the torsional effect of the spring.

Schliesslich ist in den Figuren 3 und 4 ein Ausführungsbeispiel einer Schneidmatrize 30 dargestellt. Diese umfasst einen peripheren Ring 31, der an zwei einander diametral gegenüberliegenden Seiten mit Führungen 32 versehen ist. Dank diesen Führungen 32 lässt sich die Schneidmatrize leicht auswechseln und exakt einführen. Eine Kerbung 33 dient dazu die Schneidmatrize in der korrekten Lage zu sichern. Im Innern des peripheren Ringes 31 sind eine Vielzahl von Halterippen 34 vorhanden, die eine dekorativ gebogene zentrische Schneide 35 exakt mittig halten. Die Halterippen 34 sind selbstverständlich ebenfalls als Schneiden ausgestaltet. Vorteilhafterweise ist das der Schneidmatrize folgende Führungsrohr 60 in der Formgebung der zentrischen Schneide 35 angepasst. Hierdurch wird erreicht, dass jene Teile des Gemüses, der ausserhalb des Bereiches der zentrischen Schneide 35 liegen und abgeschnitten werden, nicht in das Führungsrohr gelangen und entsprechend über die Rutsche 61, die vom Führungsrohr 60 durchsetzt wird transportierbar ist.Finally, an embodiment of a cutting die 30 is shown in Figures 3 and 4. This comprises a peripheral ring 31, which is provided on two diametrically opposite sides with guides 32. Thanks to these guides 32, the cutting die can be easily replaced and inserted exactly. A notch 33 serves to secure the cutting die in the correct position. in the Inside the peripheral ring 31, a plurality of retaining ribs 34 are provided, which hold a decorative curved central cutting edge 35 exactly centered. The holding ribs 34 are of course also designed as cutting. Advantageously, the guide tube 60 following the cutting die is adapted in the shape of the central cutting edge 35. This ensures that those parts of the vegetables, which lie outside the region of the central cutting edge 35 and are cut off, do not enter the guide tube and can be transported via the chute 61, which is penetrated by the guide tube 60.
