Abstract

The invention concerns a chopper used for chopping up, for example fresh or frozen meat. Said chopper is provided with a cutting device (5) capable of moving axially in the chopper (1) body, such that the forward stroke, and therefore the pressing zone, can be adapted to the corresponding material to be cut. For this purpose, said chopper comprises an intermediate part (21, 22) capable of being mounted removable.

Description

Die Erfindung betrifft einen Wolf für zu zerkleinerndes Schneidgut unterschiedlicher Konsistenz, insbesondere einen Fleischwolf, mit einem Wolfsgehäuse und einer darin angeordneten Fördereinrichtung für den Transport des eingespeisten Schneidgutes über eine Schneideinrichtung zu einer Förderöffnung, wobei die Schneideinrichtung im wesentlichen eine Lochscheibe und ein in Förderrichtung vor der Lochscheibe drehbares Schneidmesser aufweist.The invention relates to a wolf for to be shredded Cuttings of different consistency, especially one Meat grinder, with a wolf casing and one in it arranged conveyor for the transport of the fed Material to be cut via a cutting device a conveyor opening, the cutting device essentially a perforated disc and one in the conveying direction the perforated disc has a rotatable cutting knife.

Beim Zerkleinern von Schneidgut mit einer Konsistenz wie bei Frischfleisch in einem Wolf dieser Art mit noch geringerer Konsistenz oder ähnlichen Produkten mit geringeren Konsistenzen ist ein langer Förderweg in der Fördereinrichtung bis zu der Schneideinrichtung von Vorteil. Sobald das Schneidgut in den Bereich der Fördereinrichtung gelangt, unterliegt es einem von dieser generierten Förderdruck, und mit zunehmendem Förderweg baut sich in dem Schneidgut ein immer höherer Druck auf mit einem Maximum unmittelbar vor der Lochscheibe; er führt zu einer großen Zerkleinerungsleistung, weil das von dem Schneidmesser zerkleinerte Schneidgut mit diesem hohem Druck durch die Lochscheibe gefördert wird. Gleichzeitig ist es aber erforderlich, daß das aus der Lochscheibe austretende Schneidgut möglichst unmittelbar hinter der Lochscheibe aus dem Bereich des Wolfes entnommen wird, damit dort eine Engführung des Fertigproduktes nicht dazu führt, daß das Schneidgut wieder zusammengepreßt wird und verschmiert, sondern daß es statt dessen locker bleibt.When cutting material with a consistency like with fresh meat in a wolf of this kind with even less Consistency or similar products with lower Consistencies is a long funding path in the funding facility up to the cutting device is an advantage. As soon as the material to be cut is in the area of the conveyor arrives, it is subject to one generated by it Delivery pressure, and with increasing delivery route builds up in the material to be cut is subject to ever increasing pressure with a maximum immediately in front of the perforated disc; it leads to one great shredding performance because of the cutting knife shredded material to be cut with this high pressure is conveyed through the perforated disc. At the same time it is but required that that emerging from the perforated disc Cuttings as close to the perforated disc as possible is taken from the area of the wolf so there is no tight fitting of the finished product leads that the material to be cut is compressed again and smeared, but that it stays loose instead.

Mit einem solchen Wolf ist hingegen die Verarbeitung von festerem Schneidgut wie etwa von Gefrierfleisch nur eingeschränkt möglich. Das in Partikeln bestimmter Größe der Fördereinrichtung zugeführte Schneidgut neigt dazu, daß unter zu hohem Förderdruck die Partikel wieder zusammenfrieren und die Fördereinrichtung blockieren, so daß sie nicht mehr zerkleinert werden können. Deshalb muß ein für ein derartiges Schneidgut bestimmter Wolf anders beschaffen sein: das Schneidgut darf bei ihm nur einem kurzen Förderweg bis in die Schneideinrichtung unterzogen werden, damit der Druck im Schneidgut auf niedrigem Niveau verbleibt. Hingegen spielt der in dem Wolf bis zu der Förderöffnung verbleibende Weg im Anschluß an die Verarbeitung des Schneidgutes in der Schneideinrichtung nur eine untergeordnete Rolle, weil das nach wie vor gefrorene Schneidgut nicht zum Zusammenbacken neigt und deshalb nicht verschmieren kann.With such a wolf, however, is the processing of solid sliced goods such as frozen meat only to a limited extent possible. That in particles of certain size Material fed to the conveyor tends to if the delivery pressure is too high, freeze the particles together again and block the conveyor so that it can no longer be shredded. Therefore a must for procure such a cutting material certain wolf differently be: the material to be cut may only be a short one Conveyed to the cutting device so that the pressure in the material to be cut is at a low level remains. On the other hand, he plays up to in the wolf the conveyor opening remaining path following the Processing of the material to be cut in the cutting device only a subordinate role because the still frozen Cuttings do not tend to cake and therefore cannot smear.

Ein Wolf der eingangs näher bezeichneten Art ist deshalb in der Regel nur für eine der beiden verschiedenen Sorten Schneidgutes ausgelegt und zu gebrauchen. Es ist auch schon versucht worden, diesem Mangel abzuhelfen und einen Wolf so auszulegen, daß er universell anwendbar ist; dazu ist seine Druckzone - d.h. der Förderweg in der Fördereinrichtung sowie der anschließende Schneidweg in der Schneideinrichtung bis zum Austritt des Schneidgutes aus der Lochscheibe - auf einen Mittelwert gestellt worden, der dem unterschiedlichen Schneidgut natürlich jeweils nur unzureichend angepaßt sein kann. Ein solcher Kompromiß bei der Ausgestaltung der Druckzone kann eine optimale Behandlung verschieden strukturierten Schneidgutes verständlicherweise nicht gewährleisten.A wolf of the kind described in the beginning is therefore usually only for one of the two different varieties Cut goods designed and usable. It is also have already been tried to remedy this deficiency and one To interpret Wolf in such a way that it is universally applicable; to is its pressure zone - i.e. the conveyor path in the conveyor as well as the subsequent cutting path in the Cutting device until the material to be cut out the perforated disc - has been set to an average, of course, the different material to be cut can only be insufficiently adapted. Such a compromise in the design of the pressure zone can be optimal Treatment of differently structured material to be cut understandably not guarantee.

Aus der DE 36 18 051 A1 ist ein Kombinations-Fleischwolf bekannt, mit welchem durch das Verändern des Verhältnisses des Förderschnecken- bzw. des Zylindergehäuse-Durchmessers zur wirksamen Förderschnecken- bzw. Zylindergehäuse-Länge der Staudruck an der Wolfsscheibe derart beeinflußt wird, daß sowohl frisches wie auch gefrorenes Fleisch auf einer Maschine verarbeitet werden kann. Zu diesem Zweck wird das Wolfsgehäuse und die Förderschnecke durch einen entsprechenden Abschnitt verlängert.DE 36 18 051 A1 is a combination meat grinder known with which by changing the ratio of the screw conveyor or cylinder housing diameter for effective screw conveyor or cylinder housing length the back pressure on the wolf disk so affected is that both fresh and frozen Meat can be processed on a machine. To for this purpose the wolf housing and the screw conveyor extended by an appropriate section.

Die Erfindung hat sich deshalb die Aufgabe gestellt, einen derartigen Wolf der oben beschriebenen Bauart so auszubilden, daß er für ganz unterschiedliches Schneidgut hergerichtet werden kann und zwar so, daß dann aus jedem Schneidgut ein qualitativ hochwertiges Endprodukt herstellbar ist, welches in dieser Qualität ansonsten nur jeweils mit einem Gerät erreicht werden kann, das speziell für das jeweilige Schneidgut ausgelegt und für ein anderes hingegen nicht geeignet ist.The invention has therefore set itself the task to train such a wolf of the type described above, that it is for very different material to be cut can be prepared in such a way that then from each A high-quality end product can be cut which is otherwise only in this quality can be achieved with a device that is special designed for the respective material to be cut and for a other, however, is not suitable.

Erfindungsgemäß wird die Aufgabe mit den Merkmalen des Anspruches 1 gelöst. According to the invention the task with the features of Claim 1 solved.

Auf diese einfache Weise kann die Druckzone des Wolfes ganz unterschiedlichem Schneidgut optimal angepaßt werden, denn es kann mit unterschiedlichen Zwischenstücken dafür gesorgt werden, daß der Förderweg dem jeweiligen Schneidgut entsprechend verändert wird. Da der Wolf ansonsten unverändert bleibt, wandert die ohne das Zwischenstück in dem Wolf versenkt angeordnete Lochscheibe mehr oder weniger in Richtung der Förderöffnung, dabei den Förderweg in Förderrichtung nach der Lochscheibe verkürzend. Eine solche Distanzbuchse kann als einfach herzustellendes Drehteil ausgeführt werden, wobei es besonders günstig ist, wenn die Distanzbuchse - an einem Anschlagbund des Wolfsgehäuses für die Schneideinrichtung anschlagend - in das Wolfsgehäuse einsteckbar und an dessen Innenmantel radial gelagert ist; sein Ein- und Ausbau gestaltet sich dadurch einfach, so daß dazu weder Fachkenntnisse noch besondere handwerkliche Geschicklichkeit erforderlich sind.In this simple way, the pressure zone of the wolf completely different cutting goods are optimally adapted, because it can with different spacers be ensured that the funding route to the respective Material to be cut is changed accordingly. Since the wolf otherwise remains unchanged, it migrates without the intermediate piece perforated disc sunk in the wolf more or less in the direction of the delivery opening shortening the conveying path in the conveying direction after the perforated disc. Such a spacer can be easy to manufacture Turned part are executed, being special is favorable if the spacer - on a stop collar of the wolf housing for the cutting device striking - can be plugged into and attached to the wolf housing Inner jacket is mounted radially; its installation and expansion This is easy, so that neither specialized knowledge still special craftsmanship required are.

Besonders einfach kann die Erfindung an einem Wolf ausgebildet werden, bei dem die Fördereinrichtung und die Schneideinrichtung in dem rohrförmigen Wolfsgehäuse fluchtend in einer gemeinsamen Achse vorgesehen sind, die Schneideinrichtung mittels einer mit dem Wolfsgehäuse an dessen offener Stirnseite gewindeverbundenen, mit der Förderöffnung für das Fertigprodukt versehenen Spannbuchse axial spannbar ist.The invention can be embodied particularly simply on a wolf be in which the conveyor and the Cutting device in the tubular wolf housing are aligned in a common axis, the Cutting device by means of a with the wolf housing the open end of which is thread-connected, with the Delivery opening for the finished product provided clamping bush is axially clampable.

Es ist besonders zweckmäßig, wenn die Fördereinrichtung eine Förderschnecke aufweist, die zusammen mit dem Schneidmesser drehfest auf einer von einem Drehantrieb betriebenen Antriebswelle aufgebracht ist. Bei einer solchen Anordnung kann in einfacher Weise dafür gesorgt werden, daß der Transport des Schneidgutes bis in die unmittelbare Nähe der Schneideinrichtung schonend durchgeführt wird, wenn die Förderschnecke aus einem ersten, dauerhaft auf der Antriebswelle verbleibenden Schnecken-Segment und einem zweiten, zu dem Zwischenstück gehörenden und zusammen mit der Distanzbuchse leicht entfernbaren Schnecken-Segment besteht, so daß ein entsprechender Förderdruck bis zu der Lochscheibe ausgeübt wird, gleichgültig, ob diese am Ende eines langen oder eines kurzen Förderweges vorgesehen ist.It is particularly useful if the conveyor has a screw conveyor, which together with the Cutting knife rotatably on one of a rotary drive driven drive shaft is applied. With one Arrangement can be easily ensured that the transport of the material to be cut into the immediate Gently carried out near the cutting device will, if the screw conveyor from a first, permanent on the drive shaft remaining screw segment and a second, belonging to the intermediate piece and together with the spacer bush easily removable screw segment exists, so that a corresponding delivery pressure up to the perforated disc, regardless of whether this is at the end of a long or a short one Funding route is provided.

Die Förderschnecke wird zusammen mit der Antriebswelle radial sicher geführt, wenn das erste Schnecken-Segment mit seiner äußeren Mantelfläche an dem den Schneckengang kreiszylindrisch umhüllenden Innenmantel des Wolfsgehäuses und das zweite Schnecken-Segment mit seiner äußeren Mantelfläche an einem vergleichbaren Innenmantel der Distanzbuchse geführt ist; es ist am besten, wenn der Durchmesser des zweiten Schnecken-Segmentes gleich groß oder kleiner ist als der Durchmesser des ersten, so daß die Distanzbuchse keine besonders drastische Verminderung der Wandstärke an dem (umgebenden) Wolfsgehäuse erfordert.The screw conveyor is together with the drive shaft guided radially safely when the first screw segment with its outer surface on the worm gear Circular cylindrical enveloping inner casing of the wolf housing and the second snail segment with its outer Shell surface on a comparable inner jacket of the spacer sleeve is led; it is best if the Diameter of the second screw segment is the same size or smaller than the diameter of the first, so that the distance bushing is not a particularly drastic reduction the wall thickness on the (surrounding) wolf housing required.

Ein Längenausgleich findet dabei in einfacher Weise statt, indem zwischen der Spannbuchse und der Lochscheibe mindestens ein koaxialer Distanzring dann einfügbar ist, wenn das Zwischenstück aus dem Wolf entfernt ist; es läßt sich leicht so einrichten, daß die Spannbuchse zu der offenen Stirnseite des Wolfsgehäuses in gleicher axialen Zuordnung verbleibt.Length compensation takes place in a simple manner instead, by between the clamping bush and the perforated disc at least one coaxial spacer ring can then be inserted, when the adapter is removed from the wolf; it leaves easily set up so that the clamping bush to the open face of the wolf housing in the same axial Assignment remains.

Die Erfindung stellt dementsprechend mit ganz wenigen zusätzlichen, einfach geformten und leicht zu handhabenden Bauteilen sicher, daß ein Wolf der eingangs bezeichneten Art vielfältiger nutzbar und praktisch für alles Schneidgut einsetzbar ist, ohne daß die Qualität des Endproduktes berührt wäre. So ist frisches oder gefrorenes Fleisch genauso zerkleinerbar wie weicher oder sehr fester Käse oder dergleichen; jedes Schneidgut ist für die Bearbeitung in einem solchen Wolf geeignet, wenn nur die Druckzone entsprechend bemessen und die Lage der Lochscheibe in Bezug auf die Fördereinrichtung dazu passend hergestellt wird.The invention accordingly provides with very few additional, simply shaped and easy to use Components sure that a wolf of the aforementioned Kind of versatile and practical for all sliced goods can be used without affecting the quality of the end product would be touched. That's how fresh or frozen meat is can be crushed just like soft or very firm cheese or similar; every item to be cut is for processing suitable in such a wolf if only the pressure zone dimensioned accordingly and the position of the perforated disc manufactured in relation to the conveyor becomes.

An einem Wolf nach der Erfindung befindet sich entsprechend Fig.1 zunächst ein rohrförmiges Wolfsgehäuse 1, das mittels eines Halteflansches 26 mit den übrigen Baugruppen des Wolfes verbunden werden kann, insbesondere mit einem in einem Antriebsgehäuse untergebrachten Drehantrieb für eine Förderschnecke 3 und damit auch für eine Antriebswelle 2, mit deren Hilfe sowohl eine mit einer Förderschnecke 3 versehene Fördereinrichtung 4 als auch eine Schneideinrichtung 5 angetrieben werden. Zu der Fördereinrichtung 4 gehört weiterhin eine in den Innenmantel 6 des Wolfsgehäuses 1 in Länge der Förderschnecke 3 eingetiefte schraubenförmige Rille 7, welche die Förderwirkung für das Produkt verstärkt. A wolf according to the invention is located accordingly Fig.1 first a tubular wolf housing 1, the by means of a holding flange 26 with the other modules of the wolf can be connected, in particular with one housed in a drive housing Rotary drive for a screw conveyor 3 and thus also for a drive shaft 2, with the help of both one with a Conveyor screw 3 provided conveyor 4 as also a cutting device 5 are driven. To the Conveyor 4 also belongs in the inner jacket 6 of the wolf housing 1 in the length of the screw conveyor 3 recessed helical groove 7, which the conveying effect reinforced for the product.

Die Steigung der Förderschnecke 3 ist so gerichtet, daß ein in den Bereich der Fördereinrichtung 4 verbrachtes Schneidgut in einer Förderrichtung 8 transportiert wird, die mit einer dem Wolfsgehäuse 1, der Fördereinrichtung 4 und der Schneideinrichtung 5 gemeinsamen Achse 9 der Antriebswelle 2 übereinstimmt.The slope of the screw conveyor 3 is directed so that one brought into the area of the conveyor 4 Material to be cut is transported in a conveying direction 8, the one with the wolf housing 1, the conveyor 4 and the cutter 5 common axis 9 of the drive shaft 2 matches.

Die Schneideinrichtung 5 besteht aus einem mit der Antriebswelle 2 drehverbundenen Schneidmesser 10 aus radial gerichteten, an einer Messernabe 11 ansetzenden Schneidklingen 12 und einer Lochscheibe 13, die an dem Innenmantel 6 drehfest geführt ist. Eine in gleicher Weise an dem Innenmantel 6 drehfeste, großflächig durchbrochene Scheibe 14 trennt die Förderschnecke 3 von dem Schneidmesser 10, und ein wiederum drehfest an dem Innenmantel 6 geführter Lagerring 15 dient mit seiner Lagernabe 16 zur Lagerung der Antriebswelle 2; der Lagerring 15 ist wie die Lochscheibe 13 und die Scheibe 14 auch in dem Wolfsgehäuse 1 axial verschiebbar und überträgt eine von einer Spannbuchse 27 ausgeübte Spannkraft auf die eingesteckten Bauteile des Wolfes, die - außer der Förderschnecke 3 und dem Schneidmesser 10 - eine achsparallele rillenförmige Nut 17 aufweisen, die zusammen mit einem in der Zeichnung weggelassenen Noppen auf dem Innenmantel 6 in fachüblicher Weise eine Drehsicherung bilden.The cutting device 5 consists of a with the drive shaft 2 rotationally connected cutting knife 10 from radial directed cutting blades attached to a knife hub 11 12 and a perforated disc 13 on the inner jacket 6 is rotatably guided. One in the same way on that Inner jacket 6 non-rotatable, large openwork Disk 14 separates the screw conveyor 3 from the cutting knife 10, and in turn rotatably on the inner jacket 6 guided bearing ring 15 is used with its bearing hub 16 Bearing of the drive shaft 2; the bearing ring 15 is like the perforated disc 13 and the disc 14 also in the wolf housing 1 axially displaceable and transmits one of one Clamping bushing 27 exerted clamping force on the inserted Components of the wolf, which - except the screw conveyor 3 and the cutting knife 10 - an axially parallel groove-shaped Have groove 17, which together with one in the drawing omitted knobs on the inner jacket 6 in the usual way Form a rotation lock.

Die Spannbuchse 27 ist mittels eines Spanngewindes 18 mit dem Wolfsgehäuse 1 an dessen offener Stirnseite 23 verbunden und mit einer Förderöffnung 19 für das Fertigprodukt versehen.The clamping bush 27 is connected by means of a clamping thread 18 connected to the wolf housing 1 at its open end face 23 and with a conveyor opening 19 for the finished product Mistake.

Die Förderschnecke 3 ist - in Achsrichtung - zweigeteilt ausgeführt und besteht aus einem ersten Schnecken-Segment 20 und einem axial unmittelbar anschließenden zweiten Schnecken-Segment 21, welches radial und im eingebauten Zustand von einer Distanzbuchse 22 umgeben ist, die zusammen mit dem Schnecken-Segment 21 ein Zwischenstück 21,22 bildet, welches zwischen dem ersten Schnecken-Segment 20 und der Scheibe 14 eingefügt und auch wieder entnommen werden kann.The screw conveyor 3 is divided into two - in the axial direction executed and consists of a first screw segment 20 and an axially immediately following second Screw segment 21, which is radial and installed Condition is surrounded by a spacer 22, which together an intermediate piece with the screw segment 21 21, 22 forms which is between the first screw segment 20 and the disc 14 inserted and removed again can be.

Die Einzelheiten der Anordnung kommen am besten in den Fig.2,3 zum Ausdruck, die zwei unterschiedliche Gebrauchsformen des erfindungsgemäßen Wolfes veranschaulichen.The details of the arrangement come best into the Fig. 2,3 expressing the two different forms of use illustrate the wolf according to the invention.

In der Fig.2 ist der Wolf mit dem Zwischenstück 21,22 ausgerüstet, das, den Förderweg 8 in der Fördereinrichtung 4 verlängernd, die Schneideinrichtung 5 weit in Richtung auf die Förderöffnung 19 verschoben hat, so daß sich die Lochscheibe 13 nahe der Förderöffnung 19 befindet und das Fertigprodukt unmittelbar nach dem Zerkleinern den Wolf verläßt, während andererseits der Förderweg 8 für das Schneidgutes um die axiale Länge 1 des Zwischenstückes 21,22 verlängert ist. Die Distanzbuchse 22 muß nicht notwendig genauso lang sein wie das zweite Schnecken-Segment 21, wie das in der Fig.2 ausgeführt ist; eine ungefähre Übereinstimmung genügt und kann durch die axiale Lage eines Anschlagbundes 24 im Zuge des Innenmantels 6 des Wolfsgehäuse 1 für die Distanzbuchse 22 und des Stirnendes 25 des ersten Schnecken-Segmentes 20 so beeinflußt werden, daß beide Teile des Zwischenstückes 21,22 in Förderrichtung 8 etwa bündig enden. Es ist zweckmäßig, wenn die schraubenförmige Rille 7b in dem Wolfgehäuse 1 mit der Rille 7a in dem Zwischenstück 22 die gleichen geometrischen Abmessungen hat. 2 is the wolf with the intermediate piece 21, 22 equipped, the conveyor path 8 in the conveyor 4 extending, the cutting device 5 wide in Moved towards the delivery opening 19 so that the perforated disk 13 is located near the delivery opening 19 and the finished product immediately after crushing leaves the wolf while on the other hand the conveyor path 8 for the material to be cut about the axial length 1 of the intermediate piece 21.22 is extended. The spacer bush 22 does not necessarily have to be as long as the second Screw segment 21, such as that shown in Fig.2 is; an approximate match is sufficient and can be achieved by the axial position of a stop collar 24 in the course of Inner jacket 6 of the wolf housing 1 for the spacer bush 22 and the front end 25 of the first screw segment 20 are influenced so that both parts of the intermediate piece 21,22 end approximately flush in the conveying direction 8. It is useful if the helical groove 7b in the Wolf housing 1 with the groove 7a in the intermediate piece 22 has the same geometric dimensions.

Während die Anordnung der Fig.2 für relativ weiches Schneidgut geeignet ist, wird für festes Schneidgut besser diejenige der Fig.3 verwendet. Das Zwischenstück 21,22 ist aus dem Wolfsgehäuse 1 entfernt worden, so daß die Schneideinrichtung 5 weit in dessen Inneres gerückt ist und die Scheibe 14 nunmehr an dem Anschlagbund 24 anliegt. Der Förderweg 8 ist beträchtlich verkürzt. Ein an dem Wolfsgehäuse 1 drehfester Distanzring 28, dessen axiale Länge 1' der Länge 1 des Zwischenstückes 21,22 etwa gleich ist, dient zum Längenausgleich und ist zwischen dem Lagerring 15 und der Spannbuchse 27 eingefügt worden. Im übrigen bleibt der Wolf unverändert. While the arrangement of Fig.2 for relatively soft Sliced material is suitable for solid sliced material better that of Fig.3 used. The intermediate piece 21,22 has been removed from the wolf housing 1, so that the cutting device 5 moved far inside is and the disc 14 now abuts the stop collar 24. The conveyor path 8 is considerably shortened. An on the wolf housing 1 rotatable spacer ring 28, the axial length 1 'of length 1 of the intermediate piece 21,22 is approximately the same, is used for length compensation and is between the bearing ring 15 and the clamping bush 27 inserted Service. Otherwise the wolf remains unchanged.
