Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Reinigen des Messerrings eines Messerring-Zerspaners.The invention relates to a device for cleaning the knife ring Knife ring chipper.
Zerspaner dieser Art sind in DE 32 47 629 C1 beschrieben. Sie umfassen im einzelnen einen Messerring mit einem Kranz von Messerpaketen sowie zwei diese tragenden Tragringe, die jeweils an den Enden der Messerpakete angeordnet sind. Jedes Messerpaket weist ein Messer auf, das gegen die Radialrichtung geneigt ist und dessen Schneide nach innen weist. Dabei ist ferner ein Rotor vorgesehen, der koaxial zum Messerring angeordnet und von diesem umschlossen ist. Jedes Messerpaket umfaßt einen Messerträger und eine Klemmplatte, die das Messer sandwichartig zwischen sich einschließen.Machiners of this type are described in DE 32 47 629 C1. They include in each a knife ring with a ring of knife packs and two these supporting rings, each at the ends of the knife packs are arranged. Each knife package has a knife that is against the Is inclined radially and the cutting edge points inwards. It is a rotor is also provided which is arranged coaxially to the knife ring and by this is enclosed. Each knife package includes a knife holder and a clamping plate sandwiching the knife between them.
Die Messer des Messerringes unterliegen einem relativ hohen Verschleiß. Sie müssen demgemäß in gewissen Zeitabständen nachgeschliffen werden. Außerdem kommt es zu einem Festklemmen oder Festbacken von Spänen oder Trümmern von Spänen in den Spalten zwischen dem Messerträger und dem Messerring oder dem Messer und der Klemmplatte oder dem Messerpaket und den Tragringen. Diese Ablagerungen müssen beseitigt werden, um ein einwandfreies Arbeiten des Zerspaners zu gewährleisten. Dies gilt insbesondere bei Verwendung von Schleifautomaten.The knives of the knife ring are subject to relatively high wear. she must be reground accordingly at certain intervals. In addition, chips are jammed or stuck or debris from chips in the gaps between the knife holder and the knife ring or the knife and the clamping plate or the Knife package and the carrying rings. These deposits must be removed to ensure that the chipper works properly. This applies in particular when using automatic grinding machines.
Seither hat man die Reinigung manuell vor dem Nachschleifen von Messern vorgenommen. Dies ist zeitraubend. Es erfordert insbesondere teure menschliche Arbeitskraft.Since then, cleaning has been done manually before sharpening knives performed. This is time consuming. It requires expensive ones in particular human worker.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, mit
der solche Messerringe auf rationellere Weise als seither gereinigt werden
können. Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst. The invention has for its object to provide a device with
such knife rings can be cleaned in a more rational way than since then
can. This object is solved by the features of
Demgemäß wird eine Vorrichtung vorgesehen, die eine Trageinrichtung zum Aufnehmen des zu reinigenden Messerringes aufweist, ferner ein Gehäuse, weiterhin ein Antrieb, um ein Umlaufen des zu reinigenden Messerringes um seine eigene Achse bewirken, und schließlich Elemente, die auf den Messerring einwirken, beispielsweise Reinigungsbürsten und Düsen zum Aufbringen von heißem Dampf, warmem oder kaltem Wasser und anderen Reinigungsmedien. Damit läßt sich ein verschmutzter und mit Ablagerungen behafteter Messerring bei minimalem Personalaufwand rasch und gründlich reinigen.Accordingly, a device is provided which a support device for Receiving the knife ring to be cleaned, furthermore a housing, still a drive to circulate around the knife ring to be cleaned effect its own axis, and finally elements related to the Act on the knife ring, for example cleaning brushes and nozzles Apply hot steam, warm or cold water and others Cleaning media. This can be a dirty and with deposits afflicted knife ring quickly and thoroughly with minimal personnel expenditure clean.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im einzelnen
folgendes dargestellt:
Der in Figur 1 gezeigte Messerring-Zerspaner umfaßt einen feststehenden
Messerring 1. Der Messering umschließt einen Rotor 2, der auf einer
Rotorwelle 2.1 sitzt. Messerring 1 und Rotor 2 sind koaxial zueinander
angeordnet. Der Messerring 1 ist in einem Gehäuse 3 fest eingebaut. Das
Gehäuse 3 weist einen Einlauf 3.1 zum Zuführen von Hackschnitzeln auf,
ferner einen Späneaustrittskanal 3.2, der den Messerring umschließt. The knife ring chipper shown in Figure 1 comprises a
In Figur 2 sind drei Messerpakete als Bestandteil des Messerringes 1
dargestellt. Jedes Messerpaket weist ein Messer 1.1 auf. Dieses ist zwischen
einem Messerträger 1.2 und einer Klemmplatte 1.3 eingespannt. Jedes
Messerpaket ist im vorliegenden Falle mit einem sogenannten Stockmesser
1.4 versehen. Die beiden Messer, nämlich das Messer 1.1 und das Messer
1.4, bilden jeweils miteinander einen Spalt 1.5 zum Durchtritt der Späne radial
nach außen.In Figure 2, three knife packs are part of the
In Phantomlinien sind Schaufeln des Rotors dargestellt. Siehe die Schaufel
2.1, die ein Spaltmesser 2.2 trägt. Man erkennt, daß die radiale Position des
Spaltmessers 2.2 ein kritisches Maß ist. Wird dieses überschritten, so kommt
es zu einer Kollision zwischen dem Spaltmesser 2.2 und dem Messer 1.1 des
Messerringes 1.Blades of the rotor are shown in phantom lines. See the shovel
2.1, which carries a splitting knife 2.2. It can be seen that the radial position of the
Splitting knife 2.2 is a critical measure. If this is exceeded, then comes
there is a collision between the splitting knife 2.2 and the knife 1.1 of the
Knife
Die in den Figuren 3 und 4 dargestellte Reinigungsvorrichtung zeigt
gestrichelt, und damit sehr schematisch, einen Messerring 1. Dieser befindet
sich in einer Reinigungsvorrichtung 10. Die Reinigungsvorrichtung 10 umfaßt
eine Trageinrichtung. Die Trageinrichtung umfaßt zwei Tragrollen 11.1, 11.2,
auf welchen der Messerring 1 abrollen kann. Die Tragrolle 11.2 ist von einem
Motor 11.3 antreibbar. Man erkennt ferner ein Gehäuse 12. Das Gehäuse 12
weist zwei Stirnwände auf 12.1 und 12.2 auf - siehe Figur 4. Die Stirnwand
12.2 läßt sich öffnen. Ein Wagen 13 dient zum Tragen und Einfahren des
Messerringes 1 in das Innere des Gehäuses 12 auf die Tragrollen 11.1, 11.2.The cleaning device shown in Figures 3 and 4 shows
dashed, and thus very schematically, a
Im Inneren des Gehäuses sind mehrere Reinigungselemente vorgesehen.
Dabei handelt es sich um Wasserstrahldüsen 14, rotierbare Bürsten 15,
Dampfdüsen 16 und Heißwasserdüsen 17.Several cleaning elements are provided inside the housing.
These are
Wenn der Messerring 1 in die Vorrichtung 10 eingesetzt ist, so versetzt der
Motor 11.3 die Rolle 11.2 in Umlauf. Diese nimmt den Messerring 1 mit,
sodaß dieser ebenfalls umläuft. Die genannten Reinigungselemente werden
sodann aktiviert. Dies kann durch ein bestimmtes Steuerschema in einem
bestimmten Rhythmus geschehen.When the
Statt der Tragrollen 11.1, 11.2 können auch Hängerollen vorgesehen werden.
Diese wären dann im oberen Bereich der Vorrichtung 10 anzuordnen, und
zwar nicht außerhalb des Messerringes 1 sondern innerhalb, um an dessen
Innenumfang anzugreifen.Instead of the support rollers 11.1, 11.2, hanging rollers can also be provided.
These would then have to be arranged in the upper region of the
