Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schneiden von Lebensmitteln, insbesondere von Gemüse, Brot oder Käse, in Streifen- oder Würfelform, wobei ein Maga­zinstempel in einem Magazin von einem Ende aus das Schneid­gut taktweise durch eine Öffnung im Magazin am gegenüberlie­genden Ende schiebt, und wobei vor dem Magazin ein von einem Antriebsmotor aus angetriebenes Trennmesser das Schneidgut quer zur Vorschubeinrichtung abschneidet.The invention relates to a method and a device for cutting food, in particular vegetables, bread or cheese, in the form of strips or cubes, a magazine stamp in a magazine pushing the material to be sliced from one end in cycles through an opening in the magazine at the opposite end, and wherein in front of the magazine a cutting knife driven by a drive motor cuts the material to be cut transversely to the feed device.

Ein Verfahren dieser Art und eine Schneidmaschine hierfür ist z.B. in der DE-AS 17 79 153 beschrieben. Mit einer derar­ tigen Maschine können die verschiedenartigsten Lebensmittel in Streifen- oder Würfelform geschnitten werden. Das zu schneidende Gut fällt dabei von einem Vorfüllraum aus nach unten in das Magazin, welches im allgemeinen kastenförmig ist. Nach dem Schließen des Magazines durch eine Abdeckplat­te erfolgt, eventuell nach einer seitlichen, großflächigen Vorpressung durch einen seitlichen Verdichtungsstempel , das Schneiden des Gutes. Zu diesem Zwecke wird der Magazinstem­pel in Längsrichtung des Magazines von hinten her taktweise in Richtung auf ein am gegenüberliegenden Ende angeordnetes Gattermesser verschoben. Der Magazinstempel drückt damit das zu schneidende Gut durch das Gattermesser. Das Gattermesser besteht im allgemeinen aus zwei hintereinander angeordneten Reihen von jeweils parallel zueinander liegenden Messern, wo­bei eine Reihe senkrecht zur anderen Reihe liegt. Dadurch er­geben sich - im Querschnitt gesehen - eine Vielzahl von klei­nen Rechtecken, wodurch das Gut in Streifen längsgeschnitten durch das Gattermesser gedrückt wird. Zum Schneiden werden dabei die beiden senkrecht zueinander stehenden Messerrei­hen, die jeweils in einem Rahmen angeordnet sind, über die Rahmen noch in eine hin- und hergehende Schneidbewegung ver­setzt.A method of this type and a cutting machine therefor are described, for example, in DE-AS 17 79 153. With a derar machine, a wide variety of foods can be cut into strips or cubes. The material to be cut falls from a prefilling space down into the magazine, which is generally box-shaped. After the magazine has been closed by a cover plate, the material is cut, possibly after a lateral, large-area pre-pressing by means of a side compression stamp. For this purpose, the magazine stamp is shifted in the longitudinal direction of the magazine from the back in cycles towards a gate knife arranged at the opposite end. The magazine stamp thus pushes the material to be cut through the gate knife. The gate knife generally consists of two rows of knives arranged one behind the other, each lying parallel to one another, one row being perpendicular to the other row. In cross-section, this results in a large number of small rectangles, which means that the material is pressed lengthways into strips by the gate knife. For cutting, the two rows of knives which are perpendicular to one another and are each arranged in a frame are set in a reciprocating cutting movement over the frames.

Vor dem Gattermesser befindet sich ein rotierendes Trennmes­ser, das abschließend das Schneidgut in der gewünschten Län­ge quer zur Vorschubrichtung abschneidet. Auf diese Weise entsteht die Würfelform.There is a rotating cutting knife in front of the gate knife, which then cuts the material to be cut in the desired length transversely to the feed direction. In this way the cube shape is created.

Eine derartige Maschine ist insbesondere zum Schneiden von Fleisch oder von harten Lebensmitteln geeignet. Beim Schnei­den von klebrigen oder leicht haftenden Produkten, wie z.B. Käse, oder von Lebensmitteln, die sich stark komprimieren lassen, wie z.B. Brot, können sich jedoch Probleme ergeben. Tritt eine hohe Reibung während des Vorschiebens des Schneid­gutes in dem Magazin auf, wobei gleichzeitig auch in nachtei­liger Weise die Magazinwände verschmiert werden, ist eine entsprechend hohe Kraft für den Magazinstempel zum Vorschub notwendig. Weiterhin ergibt sich dadurch ein sehr unsauberer Schnitt. Gleiches gilt für Lebensmittel , die sich stark kom­primieren lassen. Auch hier wird ein sehr unsauberer Schnitt erzeugt.Such a machine is particularly suitable for cutting meat or hard food. When cutting sticky or slightly sticky products such as Cheese, or food that is highly compressible, such as Bread, however, problems may arise. If there is a high level of friction in the magazine during the advancement of the material to be cut, while the magazine walls are also smeared in a disadvantageous manner, a correspondingly high force is required for the magazine stamp to advance. This also results in a very unclean cut. The same applies to foods that can be highly compressed. Here too, a very unclean cut is created.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde ein Verfahren und eine Vorrichtung der eingangs erwähnten Art zu schaffen, mit der auch klebrige oder stark haftende sowie weiche Lebensmittel ohne besondere Schwierigkeiten in Streifen- oder Würfelform geschnitten werden können.The present invention is therefore based on the object of providing a method and a device of the type mentioned at the outset with which sticky or strongly adhering and soft foods can also be cut into strips or cubes without particular difficulty.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die nach dem Abschneiden durch das Trennmesser auf einen Rahmen mit mehreren auf Abstand zueinander liegenden Messern fallen­den Scheiben des Schneidgutes durch einen über dem Rahmen an­ geordneten und nach unten auf den Rahmen preßbaren Schneide­stempel durch den Rahmen mit den Messern gedrückt werden.According to the invention, this object is achieved in that, after cutting by the separating knife onto a frame with a plurality of spaced-apart knives, the slices of the material to be cut fall through one above the frame orderly and can be pressed downwards onto the frame by the frame with the knives.

Erfindungsgemäß wird nun nicht mehr das zu schneidende Gut in seiner Gesamtheit durch den Rahmen mit den Messern durch-­gedrückt, wobei der Magazinstempel das gesamte Schneidgut von hinter her entsprechend vorschieben muß, sondern es er­folgt erst eine Aufteilung des zu schneidenden Gutes in ein­zelne Scheiben, die anschließend einzeln durch den direkten Druck eines Schneidestempels durch den Rahmen mit den Mes­sern gedrückt werden. Dies bedeutet, zum Vorschieben des Schneidgutes, um dieses durch das Trennmesser in einzelne Scheiben abzuschneiden, ist erheblich weniger Kraftaufwand für den Magazinstempel notwendig. Durch die einzelne Behand­lung der abgetrennten Scheiben, die automatisch nach dem Trennschnitt durch das Trennmesser aufgrund des nächsten Vor­schubtaktes nach vorne umfallen und damit auf den Rahmen zu liegen kommen, lassen sich auf einwandfreie Schnitte in Wür­fel- oder Streifenform erreichen. Die von dem Schneidestem­pel zum Schneiden jeweils einer einzelnen Scheibe aufzubrin­gende Kraft ist deutlich geringer, wie die für eine Magazin­stempel zu erzeugende Kraft, wenn dieser das gesamte Schneid­gut durch ein Gattermesser drücken muß. Sind in dem Rahmen nur mehrere Reihen von Messern auf Abstand und parallel zu­einander angeordnet, erhält man eine Streifenform, sind zu­sätzlich noch quer dazu Messerreihen angeordnet, wird ein Gatterrahmen gebildet, der das Schneidgut in Würfelform schneidet. Dadurch daß der Schneidestempel das Schneidgut di­rekt durch den Rahmen drückt, wird ein sehr sauberer Schnitt auch bei einem weichen und/oder schmierenden Schneidgut er­reicht. Dies bedeutet, daß eine zusätzliche hin- und herge­hende Bewegung der einzelnen Messer im allgemeinen entfallen kann. Selbstverständlich ist es im Rahmen der Erfindung je­doch auch möglich, den Messern eine translatorische Bewegung zu erteilen.According to the invention, the material to be cut is no longer pushed through the frame with the knives in its entirety, the magazine stamp having to advance the entire material to be cut from behind, but instead the material to be cut is divided into individual slices then be pressed individually by the direct pressure of a cutting stamp through the frame with the knives. This means that much less effort is required for the magazine stamp to advance the material to be cut in order to cut it into individual slices using the cutting knife. The individual treatment of the separated slices, which automatically fall forward after the cutting cut by the cutting knife due to the next feed stroke and thus come to rest on the frame, allows perfect cuts in the form of cubes or strips to be achieved. The force to be applied by the cutting punch for cutting a single disk is significantly lower than the force to be generated for a magazine punch when the latter has to press the entire material to be cut through a gate knife. If only several rows of knives are spaced apart and parallel to one another in the frame, a strip shape is obtained, and if rows of knives are additionally arranged transversely to this, a Gate frame formed, which cuts the material to be cut into cubes. Because the cutting punch presses the material to be cut directly through the frame, a very clean cut is achieved even with a soft and / or lubricating material to be cut. This means that an additional reciprocating movement of the individual knives can generally be omitted. Of course, it is also possible within the scope of the invention to give the knives a translatory movement.

Zur Anpassung an unterschiedlich große Streifen- oder Würfel­formen ist es von Vorteil, wenn der Rahmen auswechselbar in der Ausschubabteilung angeordnet ist.To adapt to different sized stripes or cubes, it is advantageous if the frame is interchangeably arranged in the extension section.

Zum Sammeln oder zum Abtransport kann unter dem Rahmen ein Aufnahmebehälter oder ein Transportband angeordnet sein, das die in Streifen- oder Würfelform geschnittenen Teile zu ei­ner Weiterverarbeitungsstelle transportiert.For collection or removal, a receptacle or a conveyor belt can be arranged under the frame, which transports the parts cut into strips or cubes to a further processing point.

In vorteilhafter Weise wird man den Schneidestempel in Ruhe­stellung auf einem Niveau anordnen, das oberhalb der Höhe des Magazines liegt. Auf diese Weise wird der Trennschnitt und das Umkippen der abgetrennten Scheibe nicht behindert. Beim nachfolgenden Takt fährt dann der Schneidestempel nach unten und anschließend vor dem nächsten Vorschubtakt des Ma­gazinstempels wieder in seine Ruhestellung zurück.In an advantageous manner, the cutting punch will be arranged in the rest position at a level which is above the height of the magazine. In this way, the separating cut and the overturning of the cut-off pane are not hindered. At the next cycle, the cutting punch then moves down and then back to its rest position before the next feed cycle of the magazine stamp.

Der Schneidestempel kann auf beliebige Weise angetrieben wer­den. In einfacher Weise wird man hierzu eine Hydraulik- oder Pneumatikeinheit verwenden.The cutting punch can be driven in any way. A hydraulic or pneumatic unit will be used in a simple manner for this.

In einer sehr vorteilhaften Weiterbildung der Erfindung kann vorgesehen sein, daß an der vorderen Magazinöffnung eine Hal­terung für einen Rahmen eines Gattermessers angeordnet ist.In a very advantageous development of the invention, it can be provided that a holder for a frame of a gate knife is arranged on the front magazine opening.

Auf diese Weise wird eine universelle Verwendung der erfin­dungsgemäßen Vorrichtung möglich. So kann nach der vorste­hend beschriebenen Art eine Trennung des Schneidgutes erfol­gen oder auch, bei entsprechender Stillsetzung des Schneide­stempels und ggf. einer Abdeckung des Rahmens in der Aus­schubabteilung, nach einem Einsetzen eines Gattermessers in die Halterung Schneidgut in bekannter Weise geschnitten wer­den.In this way, a universal use of the device according to the invention is possible. For example, the material to be cut can be separated in the manner described above or, if the cutting punch is stopped appropriately and the frame is possibly covered in the extension department, cutting material to be cut in a known manner after inserting a gate knife into the holder.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung, aus dem weitere erfindungsgemäße Vorteile und Merkmale hervorge­hen, anhand der Zeichnung prinzipmäßig beschrieben.An exemplary embodiment of the invention, from which further advantages and features according to the invention emerge, is described in principle on the basis of the drawing.

Es zeigt:

  • Fig. 1: einen Horizontalschnitt nach Linie I-I der Fig. 2 (ohne Schneidestempel)
  • Fig. 2: eine Vorderansicht aus der Pfeilrichtung A gemäß Fig. 1 (ohne Trennmesser)
  • Fig. 3: einen Längsschnitt nach Linie III-III der Fig. 1.
It shows:
  • 1: a horizontal section along line II of FIG. 2 (without cutting stamp)
  • 2: a front view from the direction of arrow A according to FIG. 1 (without cutting knife)
  • 3 shows a longitudinal section along line III-III of FIG. 1st

Auf einem Maschinengestell 1 ist ein Magazin 2 angeordnet, dessen eine senkrechte Seitenwand 3 feststehend ist, während die andere seitliche Längswand durch einen Vorverdichtungs­stempel 4 gebildet ist. Eine Verdichtungswand 5 des Vorver­dichtungsstempels 4 stellt dabei die zweite senkrechte Sei­tenwand für das Magazin 2 dar. Selbstverständlich kann die Wand 5 auch als normale Seitenwand, wie die Seitenwand 3, ausgebildet sein.A magazine 2 is arranged on a machine frame 1, one vertical side wall 3 of which is fixed, while the other side longitudinal wall is formed by a pre-compression ram 4. A compression wall 5 of the pre-compression stamp 4 represents the second vertical side wall for the magazine 2. Of course, the wall 5 can also be designed as a normal side wall, like the side wall 3.

Über dem Magazin 2 ist eine Vorfüllkammer 7 angeordnet. Der Verdichtungsstempel 4 ist weiterhin mit einer horizontalen Abdeckplatte 9 versehen, die sich in Richtung auf die gegen­überliegende Seitenwand 3 des Magazines erstreckt. Die Brei­te der Abdeckplatte 9 ist dabei so gewählt, daß im geschlos­senen Zustande, d.h. in der vorderen Positions des Verdich­tungsstempels 4, in der die Verdichtungswand 5 die zweite Seiten- bzw. Längswand des Magazines 2 bildet, eine Einfüll­öffnung 10 zwischen dem Vorfüllraum 7 und dem Magazin 2 durch die Abdeckplatte 9 vollständig abgedeckt ist. In der Fig. 2 ist der Vorverdichtungsstempel 4 in seiner zurückgezo­ genen Position und in der Fig.1 in der vorgeschobenen Posi­tion dargestellt. Vor dem Magazin befindet sich eine Aus­schubabteilung 6, die eine Wannenform aufweist, wobei dessen Boden 8 sich ungefähr auf dem gleichen Niveau befindet wie der Boden des Magazines. In den Boden 8 der Ausschubabtei­lung 6 ist ein Rahmen 11 eingelassen, in dem mehrere Reihen von parallel und kreuzweise zueinander liegende Messer 12 befestigt sind. Auf diese Weise wird ein Gattermesser gebil­det. Vertikal über dem Rahmen 11 ist ein Schneidestempel 13 angeordnet, der in vertikaler Richtung durch eine Hydraulik­einheit 14 mit einem Zylinder und einem Kolben nach unten auf den Rahmen zu verschiebbar ist. Zwischen einer vorderen Öffnung 15 des Magazines 2 und der Ausschubabteilung 6 ist in einem Spalt ein Trennmesser 16 schwenkbar angeordnet. Hierzu kann das Trennmesser seitlich an einer Drehwelle 17 befestigt sein, die von einem nicht näher dargestellten An­triebsmotor 18 taktweise angetrieben wird.A prefilling chamber 7 is arranged above the magazine 2. The compression stamp 4 is further provided with a horizontal cover plate 9 which extends in the direction of the opposite side wall 3 of the magazine. The width of the cover plate 9 is chosen so that in the closed state, ie in the front position of the compression ram 4, in which the compression wall 5 forms the second side or longitudinal wall of the magazine 2, a filling opening 10 between the prefilling space 7 and the Magazine 2 is completely covered by the cover plate 9. 2, the pre-compression stamp 4 is retracted gene position and shown in Fig.1 in the advanced position. In front of the magazine there is an extension section 6 which has a trough shape, the bottom 8 of which is approximately at the same level as the bottom of the magazine. A frame 11 is embedded in the bottom 8 of the extension section 6, in which a plurality of rows of knives 12 lying parallel and crosswise to one another are fastened. In this way a gate knife is formed. A cutting punch 13 is arranged vertically above the frame 11 and can be displaced downwards on the frame by a hydraulic unit 14 with a cylinder and a piston. A separating knife 16 is pivotably arranged in a gap between a front opening 15 of the magazine 2 and the extension section 6. For this purpose, the cutting knife can be attached laterally to a rotary shaft 17, which is cyclically driven by a drive motor 18, not shown.

Das Magazin 2 ist auf seiner Rückseite ebenfalls offen. An dieser Stelle befindet sich ein Magazinstempel 19, der sich im wesentlichen über die Höhe und Breite des Magazines 2 er­streckt. Der Magazinstempel 19 wird ebenfalls in nicht näher dargestellter Weise durch eine Hydraulikeinheit 20 in Längs­richtung des Magazines 2 verschoben.Magazine 2 is also open on the back. At this point there is a magazine stamp 19 which extends essentially over the height and width of the magazine 2. The magazine stamp 19 is also moved in a manner not shown by a hydraulic unit 20 in the longitudinal direction of the magazine 2.

Unter der Ausschubabteilung 6 befindet sich im Bereich des Rahmens 11 ein Transportband 21. Die auf das Transportband 21 fallenden und in Streifen oder Würfel geschnittene Teile können durch das Transportband 21 zur Weiterverarbeitung oder zur Abpackung abtransportiert werden.Under the extension section 6 is in the area of Frame 11 a conveyor belt 21. The parts falling on the conveyor belt 21 and cut into strips or cubes can be transported away by the conveyor belt 21 for further processing or for packaging.

Die erfindungsgemäße Vorrichtung funktioniert nun auf folgen­de Weise.The device according to the invention now works in the following way.

Schneidgut 22 gelangt über die Vorfüllkammer 7 in das Maga­zin 2. Anschließend wird der Vorverdichtungsstempel 4 auf be­liebige Weise, z.B. wie dargestellt, durch eine mechanische Betätigungseinrichtung 23 zur Schließung des Magazines nach vorne in Pfeilrichtung verschoben. Dabei schließt die Abdeck­platte 9 das Magazin auf der Oberseite ab und die Verdich­tungswand 5 stellt die zweite Längswand des Magazines dar. Anschließend fährt der Magazinstempel 19 nach vorne und schiebt damit das Schneidgut 22, welches ggf. durch den Vor­verdichtungsstempel 4 vorkomprimiert worden ist, in Richtung auf das Trennmesser 16 vor. Dabei wird das Schneidgut 22 um die gewünschte Schnittbreite über das Trennmesser 16 hinaus verschoben, wonach ein Stopptakt eingelegt wird. Während des Stopptaktes wird über den Antriebsmotor 18 aus das Trennmes­ser 16 in Drehung versetzt und schneidet damit eine Scheibe von dem Schneidgut 22 ab. Das Trennmesser 16 wird so außer­halb angehalten, daß der weitere Vorschub des Schneidgutes 22 nicht behindert wird. Während des weiteren Vorschubes oder bereits nach dem Abtrennen der vordersten Scheibe fällt diese auf den unmittelbar davorliegenden Rahmen 11 mit den Messern 12. Wird nun der Schneidestempel 13 durch eine ent­sprechende Aktivierung der Hydraulikeinheit 14 nach unten verschoben und drückt auf die auf dem Rahmen 11 liegende Scheibe - gestrichelt in der Fig. 3 dargestellt -, so wird diese Scheibe während des weiteren Vorschubes des Schneide­stempels 13 durch die Öffnungen in dem Rahmen zwischen den Messern 12 hindurchgedrückt, wodurch die gewünschte Strei­fen- oder Würfelform entsteht.Cuttings 22 reach the magazine 2 via the pre-filling chamber 7. The precompression ram 4 is then moved in any direction, for example as shown, by a mechanical actuating device 23 for closing the magazine in the direction of the arrow. The cover plate 9 closes the magazine on the top and the compression wall 5 represents the second longitudinal wall of the magazine. The magazine stamp 19 then moves forward and thus pushes the material to be cut 22, which may have been pre-compressed by the pre-compression stamp 4, in the direction on the cutting knife 16. The material to be cut 22 is shifted beyond the cutting knife 16 by the desired cutting width, after which a stop cycle is inserted. During the stop cycle, the cutting knife 16 is set in rotation by the drive motor 18 and thus cuts a disk from the material to be cut 22. The cutting knife 16 is stopped outside so that the further advance of the material to be cut 22 is not hindered. During the further feed or after the front pane has been cut off, it falls onto the frame 11 with the knives 12 lying directly in front of it. If the cutting punch 13 is now moved downwards by a corresponding activation of the hydraulic unit 14 and presses on the pane lying on the frame 11 - dashed in the Fig. 3 -, this disc is pressed during the further advancement of the cutting punch 13 through the openings in the frame between the knives 12, whereby the desired strip or cube shape is created.

Zur seitlichen Führung der abgetrennten Scheibe dienen Sei­tenwände der Ausschubabteilung.Side walls of the extension department are used for lateral guidance of the separated disc.

In den Fig. 1 und 3 ist vor der vorderen Magazinöffnung 15 gestrichelt eine Halterung 24 dargestellt, in die im Bedarfs­falle ein Gatterahmen mit Gattermessern einschiebbar oder an diesem befestigbar ist. Auf diese Weise kann im Bedarfs­falle mit der gleichen Vorrichtung auch auf herkömmliche Wei­se, z.B. Fleisch, zuerst in Längsstreifen geschnitten und an­schließend durch das Trennmesser 16 in Würfelform gebracht werden.1 and 3, a holder 24 is shown in dashed lines in front of the front magazine opening 15, into which, if necessary, a gate frame with gate knives can be inserted or attached to it. In this way, if necessary, the same device can also be used in a conventional manner, e.g. Meat, first cut into longitudinal strips and then cut into cubes by the cutting knife 16.
