Description

Verstellvorrichtung für die Messertrommel von Entfleischungsmaschinen Es sind bereits Entfleischungsmaschinen bekannt, bei denen die faserhaltigen Pflanzenteile in den Spalt zwischen einer Brustplatte und einer exzentrisch zu dieser Platte umlaufenden Messertrommel eingeführt werden. Die Pflanzenteile, insbesondere Agavenblätter, werden hierbei u. a. zwischen Förderseilen @o. dgl. in Trommelachsenrichtung durch den genannten Spalt hindurchgezogen. Um den Eintritt der Pflanzenteile in den Spalt zu @erleichtern, pflegt man dabei der Brustplatte konische Gestalt zu geben, so daß sich der Spalt von der Eintrittsseite zur Austrittsseite hin keilförmig verjüngt.Adjustment device for the knife drum of meat removal machines Defleving machines are already known in which the fiber-containing plant parts in the gap between a breast plate and an eccentric to this plate revolving Knife drum are introduced. The parts of the plant, especially agave leaves, are here inter alia. between hoisting ropes @o. Like. In the direction of the drum axis pulled through the said gap. Around the entry of the plant parts into the gap To @ facilitate, one usually gives the breastplate a conical shape, like that that the gap tapers in a wedge shape from the entry side to the exit side.

Da man die Breite des genannten Spaltes sehr genau einstellen und möglichst auch während des Betriebes nachstellen muß, hat man bereits vorgeschlagen, entweder den Mäntelteil gegen die Achse der Messertrommel verschiebbar zu machen oder die Lauflager der Messertrommel auf einer Buchse anzuordnen, welche ihrerseits @exzentrisch um eine schwere Welle mit exzentrischen Lagerzapfen verstellbar ist. Durch eine solche doppelt exzentrische Lagerung kann man eine Welle bekanntlich in beiden Koordinaten der senkrecht zu ihrer Drehachse liegenden Ebene beliebig verschieben.Since you set the width of the mentioned gap very precisely and If possible, must also readjust during operation, it has already been suggested that either to make the jacket part displaceable against the axis of the cutterhead or to arrange the running bearings of the cutterhead on a bushing, which in turn @ eccentric is adjustable around a heavy shaft with eccentric bearing journals. As is well known, a shaft can be created by such a double eccentric mounting arbitrary in both coordinates of the plane lying perpendicular to its axis of rotation move.

Bei der erstgenannten Bauart muß man schwere und genau eingeschliffene Kreuzschlittenführungen verwenden, um den Mantelteil in beiden Koordinaten mit ausreichender Genauigkeit zu führen. Die an zweiter Stelle genannte Bauart läßt nur die Benutzung von Gleitlagern als Lauflager für die Messiertrommel zu, da die Anwendung der beschriebenen doppelt exzentrischen Lagerung zu einem Lauflagerdurchmesser führt, welcher für die Benutzung von wohlfeilen Kugellagern zu groß ist. Die Erfindung betrifft eine Bauart, Urelche zwar ebenfalls eine doppelt exzentrische Lagerung der Messertrommel vorsieht, welche aber für die Messertrommel die Benutzung eines Lauflagers normaler Abmessungen ermog-, licht, das sich infolgedessen auch leicht ;Üjs ,: Kugellager ausbilden läßt. Nach der Erfin düng liegt das Lauflager für die Messertrommel auf einer Buchse, die exzentrisch um eine verhältnismäßig dünne Welle verstellbar ist, welche ihrerseits an den Enden Exzenterscheiben trägt, die in festen Lagern verstellbar sind. Hierdurch wird erreicht, .daß nur noch eines der beiden Verstellager (nämlich die exzentrisch gelagerte Buchse) innerhalb des Lauflagers der Messertrommel liegt und daß der Durchmesser des Lauflagers -daher entsprechend verkleinert werden 'kam.In the case of the first type, heavy and precisely grounded ones have to be used Use compound slide guides to move the shell part in both coordinates with sufficient Accuracy to guide. The type mentioned in the second place can only be used of plain bearings as running bearings for the Messiertrommel, since the application of the described double eccentric bearing leads to a bearing diameter which is suitable for the use of cheap ball bearings is too great. The invention relates to a design, Urelche also have a double eccentric bearing the cutterhead provides, but which for the cutterhead the use of a Running bearing of normal dimensions allows light, which is also easy as a result ; Üjs,: can train ball bearings. According to the invention of the fertilizer is the bearing for the Cutter drum on a bushing that is eccentric around a relatively thin shaft is adjustable, which in turn carries eccentric disks at the ends, which are fixed in place Bearings are adjustable. This means that only one of the two is left Adjustment bearing (namely the eccentrically mounted bush) within the bearing the cutterhead and that the diameter of the bearing -therefore accordingly be scaled down 'came.

Die Zeichnung erläutert ein Ausführungsbeispiel der Erfindung. Fig. i zeigt einen senkrechten Axialschnitt durch die Messertrommel und ihre Lagerung: Fig.2 gibt die Seitenansicht des festen Lagers i g und Fig. 3 einen Schnitt nach der in Fig. i eingezeichneten Linie III-III wieder.The drawing explains an embodiment of the invention. Fig. i shows a vertical axial section through the cutterhead and its bearing: FIG. 2 shows the side view of the fixed bearing i g and FIG. 3 shows a section the line III-III drawn in FIG.

Die Messertrommel besteht aus einer Scheibe 4, an deren Umfang die Felge 5 mittels der Schraubenbolzen 6 befestigt ist. Auf der Felge 5 sitzen die Entfleischungsmesser 7. Die Nabe 8 der Scheibe 4 ist mit der Riemenscheibe g durch die Schraubenbolzen i o verbunden und mittels der als Lauflager dienenden Kugellager i i und 12, zwischen denen ein Distanzring 14 liegt, auf der Buchse 13 gelagert. Die Buchse 13 besitzt eine exzentrische Bohrung 15: Durch diese Bohrung ist die ` Welle 16 hindurchgeführt, Auf die beider-' 'seitigen Enden der Welle 16 sind .die Exzenterscheiben r 7 und 18 aufgekeilt, die in den festen Lagern ig und 2o liegen.The cutterhead consists of a disc 4, on the circumference of which Rim 5 is fastened by means of screw bolts 6. On the rim 5 sit the Defleving knife 7. The hub 8 of the disc 4 is through with the pulley g the screw bolts i o connected and by means of the ball bearings serving as running bearings i i and 12, between which a spacer ring 14 is located, mounted on the socket 13. The socket 13 has an eccentric hole 15: Through this hole is the `` Shaft 16 passed through, on both- '' ends of the shaft 16 are .the Eccentric disks r 7 and 18, which are located in the fixed bearings ig and 2o.

Die Einstellung der Messertrommel4-7 gegen den (nicht gezeichneten) Mantelteil erfolgt einerseits durch Verstellen der Buchse 13 auf ihrer exzentrischen Trägerwelle 16; andererseits durch Verstellung der die Welle 16 tragenden Exzenterscheiben 17; 18 innerhalb der festen Läger ig und 20. Zur Verstellung der Buchse 1 3 dient der Drehhebel 21. Zur Verstellung der Welle 16 dient der Drehhebel 22.The setting of the cutterhead 4-7 against the (not shown) Shell part takes place on the one hand by adjusting the socket 13 on its eccentric Carrier shaft 16; on the other hand, by adjusting the eccentric disks carrying the shaft 16 17; 18 within the fixed bearings ig and 20. To adjust the socket 1 3 is used the rotary lever 21. The rotary lever 22 is used to adjust the shaft 16.
