Said regulating body is mounted in such a way as to be axially displaceable in relation to the non-displaceable cutting heads (10.1, 10.3), hereby enabling the distance between the apertured plates (9.1, 9.3) and the corresponding cutting head to be adjusted simultaneously. At least one other apertured plate (9.2, 9.4) is located between said two apertured plates (9.1, 9.3) and is supported relative to the adjacent apertured plates (9.1, 9.3) by distance rings (21.2, 21.4).

Description

Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes Device for comminuting a material to be comminuted
Die Erfindung betrifft eine Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes, insbesondere für die fleischverarbeitende Industrie, mit zwei aus jeweils einer Lochplatte und einem davor rotierenden Schneidkopf mit Schneidklingen bestehenden Schneidsätzen mit einstellbarem Spalt zwischen der jeweiligen Lochplatte und den Schneidklingen des Schneidkopfes, wobei die Lochplatten gegen Anschläge innerhalb eines gemeinsamen Stellkörpers gehalten sind, der axial gegenüber den unverstellbar angeordneten Schneidköpfen verstellbar gelagert ist und die Lochplatten gemeinsam in ihrem /Abstand zum zugehörigenThe invention relates to a device for shredding a comminution material, in particular for the meat processing industry, with two cutting sets, each consisting of a perforated plate and a rotating cutting head with cutting blades, with an adjustable gap between the respective perforated plate and the cutting blades of the cutting head, the perforated plates against stops within a common actuator body is held, which is axially adjustable relative to the non-adjustable cutting heads and the perforated plates together in their / distance to the associated
Schneidkopf verstellt.Cutting head adjusted.
Eine derartige Vorrichtung ist aus der DE 29 15 409 AI bekannt. Diese Vorrichtung hat erhebliche Vorteile, was die Verstellbarkeit der Lochplatten und der Schneidklingen anbelangt. Hierdurch wird die Qualität des Zerkleinerungsverfahrens wesentlich verbessert.Such a device is known from DE 29 15 409 AI. This device has considerable advantages in terms of the adjustability of the perforated plates and the cutting blades As. This significantly improves the quality of the shredding process.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Zerkleinerungs- und auch Emulgationsgrad der Vorrichtung nochmals zu verbessern.The object of the present invention is to further improve the degree of comminution and also emulsification of the device.
Zur Lösung dieser Aufgabe führt, dass zwischen den beiden Lochplatten zumindest eine weitere Lochplatte angeordnet ist, die sich gegenüber den benachbarten Lochplatten über Distanzringe abstützt.To achieve this object, at least one further perforated plate is arranged between the two perforated plates, which is supported relative to the adjacent perforated plates via spacer rings.
Durch den Einsatz von mindestens drei Lochplatten und entsprechenden Schneidköpfen kann das Eingangsprodukt gröber sein, ohne das Ausgangsprodukt zu beeinflussen. Bei gleichem Eingangsprodukt wird das "Ausgangsprodukt gegenüber einer Zweiplattenvorrichtung feiner und besser emulgiert.By using at least three perforated plates and corresponding cutting heads, the input product can be coarser without influencing the output product. With the same input product, the " output product is emulsified more finely and better than a two-plate device.
Werden vier oder auch mehr Platten hintereinander eingesetzt, kann das Ausgangsprodukt nochmals verbessert werden .If four or more plates are used one after the other, the starting product can be further improved.
In einem bevorzugten Ausführungsbeispiel sind die Distanzringe gleich ausgebildet, so dass die Herstellkosten verringert werden können. In diesem Fall werden die Distanzringen in den Stellkörper eingeschoben und treffen aufeinander. Sie werden letztendlich zwischen einem Flansch eines Stirnringes und einem Spannring verspannt. Zumindest einige der dazwischen angeordneten Lochplatten können gegen federgelagerte Druckbolzen, die sich in den Distanzringen befinden, abgestützt werden.In a preferred embodiment, the spacer rings are of identical design, so that the manufacturing costs can be reduced. In this case, the spacer rings are inserted into the actuator body and meet. They are ultimately clamped between a flange of a face ring and a clamping ring. At least some of the perforated plates arranged in between can be supported against spring-loaded pressure bolts which are located in the spacer rings.
Bei einem anderen Ausführungsbeispiel ist vorgesehen, dass zumindest ein Teil der Lochplatten zwischen den Distanzringen und separaten Spannringen eingespannt wird. Hierdurch kann die Feststellung der Lochplatten verbessert werden, so dass nicht die Gefahr besteht, dass die Lochplatten mit den Schneidköpfen mitdrehen. In diesem Fall ist auch vorgesehen, dass sich die Distanzringe gegen Ringschultern in dem Stellkörper abstützen. Das bedeutet, dass die Distanzringe zwischen diesen Ringschultern und den Spannringen eingespannt sind. Hierdurch ist der Zusammenbau des gesamten Zerkleinerungsbereiches erleichtert.Another exemplary embodiment provides that at least some of the perforated plates are clamped between the spacer rings and separate clamping rings. In this way, the fixing of the perforated plates can be improved, so that there is no risk that the perforated plates rotate with the cutting heads. In this case it is also provided that the spacer rings are supported against ring shoulders in the actuating body. This means that the spacer rings are clamped between these ring shoulders and the tension rings. This simplifies the assembly of the entire shredding area.
Im übrigen werden die Lochplatten bevorzugt gegen die Ringanschläge von der gleichen Seite her gehalten, die in einem vorgegebenen Abstand innerhalb des Stellkörpers ausgebildet sind.In addition, the perforated plates are preferably held against the ring stops from the same side, which are formed at a predetermined distance within the actuating body.
Die vorliegende Erfindung umfasst auch ein Verfahren zum Zerkleinern eines Zerkleinerungsgutes, insbesondere für die fleischverarbeitende Industrie, mit aus zumindest einer Lochplatte und einem davor rotierenden Schneidkopf mit Schneidklingen bestehenden Schneidsatz mit einstellbarem Spalt zwischen der jeweiligen Lochplatte und den Schneidklingen des Schneidkopfes, wobei die Lochplatte gegen Anschläge innerhalb eines Stellkörpers gehalten ist, der axial gegenüber dem unverstellbar angeordneten Schneidkopf verstellbar gelagert ist und die Lochplatte in ihrem Abstand zum Schneidkopf verstellt. Wesentlich ist dabei, dass der Spalt zwischen Lochplatte und Schneidklinge beim Abschalten des Antriebs für den Schneidkopf vergrössert (Warteposition) bzw. beim Anlaufen des Antriebes verringert (Arbeitsposition) wird.The present invention also encompasses a method for comminuting a comminuted product, in particular for the meat processing industry, with a cutting set consisting of at least one perforated plate and a rotating cutting head with cutting blades with an adjustable gap between the respective perforated plate and the cutting blades of the cutting head, the perforated plate against stops is held within an actuating body, which is axially adjustable relative to the non-adjustable cutting head and adjusts the perforated plate in its distance from the cutting head. It is essential that the gap between the perforated plate and the cutting blade is enlarged when the drive for the cutting head is switched off (waiting position) or is reduced when the drive starts up (working position).
Der Schneidkopf befindet sich, wie oben erwähnt, auf der Hauptmotorwelle und ist dort festgelegt. Befindet sich das Zerkleinerungsprodukt im Gehäuse und dreht der Schneidkopf, so drückt er das Produkt durch die Lochplatte bei gleichzeitigem Schneiden. Dabei wirken hohe Kräfte auf den Schneidkopf und somit auch auf die Welle. Diese Kräfte bewirken, dass die Welle zurückgedrückt wird.As mentioned above, the cutting head is located on the main motor shaft and is fixed there. If the comminution product is in the housing and the cutting head turns, it pushes the product through the perforated plate while cutting at the same time. High forces act on the Cutting head and thus also on the shaft. These forces cause the shaft to be pushed back.
Beim Abschalten des Hauptmotors lassen auch die von dem Zerkleinerungsprodukt ausgehenden Kräfte nach und die Haupt otorwelle bewegt sich in entgegengesetzter Richtung. Das bedeutet, dass bei jedem Ein- und Abschalten der Maschine ein unnötiger Verschleiss an den Schneidklingen und Schneidköpfen stattfindet. Aus diesem Grunde ist vorgesehen, dass die Schneidköpfe bei stehendem Hauptmotor eine andere Position, nämlich die Warteposition, einnehmen, als bei der Arbeitsposition, beim laufenden Hauptmotor. In der Warteposition halten die Schneidklingen ein grösseren Abstand von der Lochplatte ein als in der Arbeitsposition = Scherposition. When the main motor is switched off, the forces emanating from the comminution product also decrease and the main motor shaft moves in the opposite direction. This means that every time the machine is switched on and off, there is unnecessary wear on the cutting blades and cutting heads. For this reason, it is provided that the cutting heads assume a different position, namely the waiting position, when the main motor is at a standstill, than when the main motor is in the working position. In the waiting position, the cutting blades keep a greater distance from the perforated plate than in the working position = shear position.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt inFurther advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
Figur 1 einen teilweise dargestellten Längsschnitt durch einen Zerkleinerungsbereich einer erfindungsgemässen Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes ;1 shows a partially shown longitudinal section through a shredding area of a device according to the invention for shredding a material to be shredded;
Figuren 2 und 3 Längsschnitte durch weitere Ausführungsbeispiele von Zerkleinerungsbereichen von Vorrichtungen ge äss Figur 1.FIGS. 2 and 3 are longitudinal sections through further exemplary embodiments of comminution areas of devices according to FIG. 1.
Gemäss Figur 1 ist von einer Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes, etwa entsprechend der DE 39 15 409 A 1, im wesentlichen nur ein Zerkleinerungsbereich 1 gezeigt. Dieser Zerkleinerungsbereich 1 weist eine Eintrittsöffnung 2 für das Zerkleinerungsgut sowie einen Auswurfbereich 3 auf, der im vorliegenden Ausführungsbeispiel von einer Haube 4 abgedeckt ist.According to FIG. 1, essentially only one shredding area 1 is shown of a device for shredding a shredded material, roughly in accordance with DE 39 15 409 A1. This shredding area 1 has an inlet opening 2 for the shredded material and an ejection area 3, which is covered by a hood 4 in the present exemplary embodiment.
Das Zerkleinerungsgut wird von der Eintrittsöffnung 2 zum Auswurfbereich 3 parallel zu einer Längsachse 5 einer Antriebswelle 6 gefördert, wobei die Antriebswelle 6 durch die Eintrittsöffnung 2 in ein etwa zylindrisches Gehäuse 7 einragt, welche einerseits mit einem Einlauftrichter 8 in Verbindung steht und andererseits von der Haube 4 abgedeckt ist .The comminuted material is conveyed from the inlet opening 2 to the discharge area 3 parallel to a longitudinal axis 5 of a drive shaft 6, the drive shaft 6 protruding through the inlet opening 2 into an approximately cylindrical housing 7, which is connected to an inlet funnel 8 on the one hand and from the hood on the other hand 4 is covered.
In dem Gehäuse 7 sind drei Schneidsätze A, B und C vorgesehen. Jeder Schneidsatz A, B und C besteht aus einer Lochplatte 9.1, 9.2 und 9.3 sowie einem Schneidkopf 10.1, 10.2 und 10.3, welcher Schneidklingen 11.1, 11.2 und 11.3 aufweist. Die Schneidklingen 11.1, 11.2 und 11.3 streifen an den Lochplatten 9.1, 9.2 und 9.3 entlang bzw. sind in einem Abstand etwa gleich Null entlang den Lochplatten geführt. Bohrungen 12.3 in der Lochplatte 9.3 sind grösser als Bohrungen 12.2 in der Lochplatte 9.2. Diese sind wiederum grösser als Bohrungen 12.1 in der Lochplatte 9.1.Three cutting sets A, B and C are provided in the housing 7. Each cutting set A, B and C consists of a perforated plate 9.1, 9.2 and 9.3 and a cutting head 10.1, 10.2 and 10.3 which has cutting blades 11.1, 11.2 and 11.3. The cutting blades 11.1, 11.2 and 11.3 graze along the perforated plates 9.1, 9.2 and 9.3 or are in a distance of approximately zero along the perforated plates. Holes 12.3 in the perforated plate 9.3 are larger than holes 12.2 in the perforated plate 9.2. These are again larger than holes 12.1 in the perforated plate 9.1.
Die Schneidköpfe 10.1 bis 10.3 sitzen drehfest auf der Antriebswelle 6 und drehen mit der Antriebswelle 6 um die Längsachse 5. Die Lochplatten 9.1 bis 9.3 sind dagegen ortsfest in einem hülsenförmigen Stellkörper 13 angeordnet. Dieser sitzt wiederum in dem Gehäuse 7, wobei ein Aussengewindeabschnitt 14 an dem Stellkörper 13 in einen Innengewindeabschnitt 15 an dem Gehäuse 7 eingreift. Beim Drehen des Stellkörpers 13 kann dadurch dieser Stellkörper 13 in Richtung der Längsachse 5 bewegt werden, wobei die Lochplatten 9.1 - 9.3 mitgenommen und hierdurch der Abstand jeder Lochplatte zu der entsprechneden Schneidklinge 11.1 - 11.3 verändert wird.The cutting heads 10.1 to 10.3 sit on the drive shaft 6 in a rotationally fixed manner and rotate with the drive shaft 6 about the longitudinal axis 5. The perforated plates 9.1 to 9.3, on the other hand, are arranged in a stationary manner in a sleeve-shaped adjusting body 13. This in turn is seated in the housing 7, with an external thread section 14 on the actuating body 13 engaging in an internal thread section 15 on the housing 7. When the adjusting body 13 is rotated, this adjusting body 13 can thereby be moved in the direction of the longitudinal axis 5, the perforated plates 9.1-9.3 being carried along and the distance of each perforated plate from the corresponding cutting blade 11.1-11.3 being changed thereby.
Das Drehen des Stellkörpers 13 geschieht bevorzugt über ein nicht näher gezeigtes Schneckengetriebe oder auch einen Schrittmotor auf dessen Abtriebswelle ein entsprechendes Ritzel sitzt, welches mit einer Verzahlung 16 eines Stirnrandes 17 in Eingriff steht. Dieses Stirnrand 17 ist durch entsprechende Schrauben 18 mit dem Stellkörper 13 verbunden .The actuating body 13 is preferably rotated via a worm gear (not shown in more detail) or also a stepper motor on the output shaft of which a corresponding pinion is seated, which meshes with a payment 16 of an end edge 17. This end edge 17 is connected to the actuating body 13 by corresponding screws 18.
Im vorliegenden Ausführungsbeispiel ragt vom Stirnrad 17 ein Innenflansch 19 in den Stellkörper 13 und bildet einen Ringanschlag 20.3 für die Lochplatte 9.3 aus. Andererseits trifft auf die Lochplatte 9.3 ein Distanzring 21.3 mit federgelagerten Druckbolzen 22.3. Diese Druckbolzen 22.3 drücken die Lochplatte 9.3 gegen den Ringanschlag 20.3, um eine sich ändernde Lochplattendicke zu korrigieren. Der Distanzring 21.3 bildet wiederum einen Ringanschlag 20.2 für die Lochplatte 9.2 aus, die sich ebenfalls durch federgelagerte Druckbolzen 22.2 gegen diesen Ringanschlag 20.2 gedrückt wird.In the present exemplary embodiment, an inner flange 19 projects from the spur gear 17 into the actuating body 13 and forms an annular stop 20.3 for the perforated plate 9.3. On the other hand, a spacer ring 21.3 with spring-loaded pressure bolts 22.3 meets the perforated plate 9.3. These pressure bolts 22.3 press the perforated plate 9.3 against the ring stop 20.3 in order to correct a changing perforated plate thickness. The spacer ring 21.3 in turn forms a ring stop 20.2 for the perforated plate 9.2, which is also pressed against this ring stop 20.2 by spring-loaded pressure bolts 22.2.
Der Druckbolzen 22.2 befindet sich in einem weiteren Distanzring 21.2, der wiederum einen Ringanschlag 20.1 für die Lochplatte 9.1 ausbildet.The pressure pin 22.2 is located in a further spacer ring 21.2, which in turn forms a ring stop 20.1 for the perforated plate 9.1.
Den Abschluss der Schneidsätze A, B und C bildet dann ein in den Stellkörper 13 eingeschraubter Spannring 23.1.The conclusion of the cutting sets A, B and C then forms a clamping ring 23.1 screwed into the adjusting body 13.
Von der Haube 4 überdeckt, sitzt auf der Antriebswelle 6 ein Auswerfer 24.Covered by the hood 4, an ejector 24 sits on the drive shaft 6.
Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:
Zerkleinerungsgut, insbesondere Brät, wird durch die Eintrittsöffnung 2 eingeführt und gelangt in den Bereich von Schneidsatz C. Die Lochplatte 9.3 steht still, während der Schneidkopf 10.3 mit der Antriebswelle 6 dreht, so dass das Schneidgut während dem Eindrücken in die Bohrungen 12.3 durch die Messerklingen 11.3 zerkleinert wird. In den Bohrungen 12.3 mit dem grössten Durchmesser findet eine grobe Vorzerkleinerung statt.Comminuted material, in particular sausage meat, is introduced through the inlet opening 2 and reaches the area of the cutting set C. The perforated plate 9.3 stands still while the cutting head 10.3 rotates with the drive shaft 6, so that the material to be cut is pressed into the holes 12.3 by the knife blades 11.3 is crushed. A rough pre-shredding takes place in the holes 12.3 with the largest diameter.
Von dem Schneidsatz C gelangt das Brät zu dem Schneidatz B mit der Lochplatte mit den Bohrungen 12.2 mittleren Durchmessers . Auch hier wird das Brät in diese Bohrungen 12.2 hineingedrückt und gleichzeitig durch die an der Lochplatte 9.2 entlangfahrenden Schneidklingen 11.2 zerkleinert .From the cutting set C, the sausage meat reaches the cutting set B with the perforated plate with the holes 12.2 of medium diameter. Here, too, the sausage meat is pressed into these bores 12.2 and, at the same time, comminuted by the cutting blades 11.2 traveling along the perforated plate 9.2.
Nunmehr gelangt das zu zerkleinernde Gut zum Schneidsatz A, in dem die Lochplatte 9.1 mit den Bohrungen 12.1 mit dem geringsten Durchmesser angeordnet ist. Auch hier wird das Brät in diese Bohrungen 12.1 hineingedrückt und beim Hineindrücken durch die Schneidklingen 11.1 weiter zerkleinert .Now the material to be shredded reaches the cutting set A, in which the perforated plate 9.1 with the bores 12.1 with the smallest diameter is arranged. Here, too, the sausage meat is pressed into these bores 12.1 and further crushed when it is pushed in by the cutting blades 11.1.
Schliesslich gelangt das zerkleinerte Gut in den Auswurfbereich 3, in dem es von dem Auswerfer 24 einer nicht näher gezeigten AuswurfÖffnung zugeführt wird.Finally, the comminuted material arrives in the ejection area 3, in which it is fed by the ejector 24 to an ejection opening (not shown in more detail).
Wird festgestellt, dass die Tätigkeit zwischen Schneidklingen und Lochplatten nicht mehr optimal ist, muss der Abstand zwischen Schneidklingen und Lochplatten verstellt werden. Hierzu wird der nicht näher gezeigte Antrieb in Tätigkeit gesetzt, so dass er über das Verzahnung 16 das Stirnrad 17 und mit dem Stirnrad 17 auch den Stellkörper 13 dreht. Dabei kämmt das Innengewinde 15 in dem Aussengewinde 14, so dass der Stellkörper 13 entlang der Längsachse 5 bewegt wird.If it is determined that the activity between the cutting blades and perforated plates is no longer optimal, the distance between the cutting blades and perforated plates must be adjusted. For this purpose, the drive (not shown in detail) is activated so that it rotates the spur gear 17 via the toothing 16 and also the actuating body 13 with the spur gear 17. The internal thread 15 meshes in the external thread 14 so that the actuating body 13 is moved along the longitudinal axis 5.
Ein Zerkleinerungsbereich 1.1 nach Figur 2 unterscheidet sich von demjenigen nach Figur 1 dadurch, dass die Distanzringe eine unterschiedliche Ausgestaltung aufweisen und insbesondere einen unterschiedlichen Durchmesser besitzen. Ferner weist nur der Distanzring 21.3 einen federbelasteten Druckbolzen 22.3 auf. Die Lochplatte 9.2, welche in dem Anschlag 22.2 des Distanzringes 21.3 sitzt, wird in diesem Anschlag 22.2 von einem weiteren Spannring 23.2 gehalten, der in den Stellkörper 13.1 eingeschraubt ist .A shredding area 1.1 according to FIG. 2 differs from that according to FIG. 1 in that the spacer rings have a different design and in particular have a different diameter. Furthermore, only the spacer ring 21.3 has a spring-loaded pressure pin 22.3. The perforated plate 9.2, which is seated in the stop 22.2 of the spacer ring 21.3, is held in this stop 22.2 by a further clamping ring 23.2, which is screwed into the actuating body 13.1.
Der Distanzring 21.2 weist einen grösseren Durchmesser auf als der Distanzring 21.3 und sitzt in einer Ringschulter 25, die in den Stellkörper 13.1 eingeformt ist. Das Ausführungsbeispiel eines Zerkleinerungsbereiches 1.2 gemäss Figur 3 unterscheidet sich von demjenigen nach Figur 2 dadurch, dass noch ein weiterer Schneidsatz D in einen Stellkörper 13.2 eingesetzt ist. Dieser Schneidsatz D besitzt einen Distanzring 21.4, der wiederum einen Ringanschlag 20.4 für eine Lochplatte 9.4 ausbildet. An diesem Ringanschlag 20.4 wird die Lochplatte 9.4 durch einen weiteren Spannring 23.4 gehalten. Der Distanzring 21.4 sitzt wiederum in einer Ringschulter 25.4 in dem Stellkörper 13.2.The spacer ring 21.2 has a larger diameter than the spacer ring 21.3 and is seated in an annular shoulder 25 which is molded into the actuating body 13.1. The exemplary embodiment of a comminution area 1.2 according to FIG. 3 differs from that according to FIG. 2 in that a further cutting set D is inserted into an adjusting body 13.2. This cutting set D has a spacer ring 21.4, which in turn forms a ring stop 20.4 for a perforated plate 9.4. The perforated plate 9.4 is held on this ring stop 20.4 by a further clamping ring 23.4. The spacer ring 21.4 is in turn seated in an annular shoulder 25.4 in the actuating body 13.2.
Auf den Schneidsatz D folgt zum Auswurfbereich hin der Schneidatz A, zur Eintrittsöffnung 2 hin der Schneidsatz B und darauf der Schneidsatz C. The cutting set D is followed by the cutting set A towards the ejection area, the cutting set B towards the inlet opening 2 and then the cutting set C.
