Description
Die Erfindung betrifft eine Messerbefestigung bei Holzhack maschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a knife attachment at Holzhack machines according to the preamble of patent claim 1.
Eine Messerbefestigung dieser Gattung ist aus der US-PS 35 42 302 bekannt. Bei diesem Stand der Technik sind die Messer an der Hackscheibe mittels Schrauben befestigt, die durch zwei die Messer zwischen sich einklemmende Haltestücke und durch die Hackscheibe verlaufen. Die Schrauben sind hierbei vergleichs weise groß und erfordern daher zum Festziehen und Lösen ein entsprechend hohes Drehmoment. Die Folge ist, daß das Auswech seln der Messer aufwendig ist und üblicherweise von mindestens zwei Personen durchgeführt werden muß.A knife attachment of this type is from the US PS 35 42 302 known. The knives are in this state of the art attached to the chopping disc by means of screws, which are by two the knives between clamped holding pieces and through the Chopping disk run. The screws are comparative as large and therefore require tightening and loosening correspondingly high torque. The result is that the exchange seln the knife is complex and usually of at least two people must be carried out.
Der Erfindung liegt die Aufgabe zugrunde, eine Messerbefesti gung der im Oberbegriff des Patentanspruchs 1 angegebenen Gat tung so weiterzubilden, daß das Auswechseln der Messer erleich tert wird.The invention has for its object a Messerbefesti supply of the Gat specified in the preamble of claim 1 training so that the replacement of the knife easier is tert.
Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeich nete Erfindung gelöst.This object is characterized in that in claim 1 nete invention solved.
Aus der FR-PS 24 77 945 ist bereits eine Holzhackmaschine be kannt, bei der Messer und Messerhalter durch getrennte Schrau ben befestigt sind. Ein Füllstück im erfindungsgemäßen Sinne ist dort allerdings nicht vorgesehen.From FR-PS 24 77 945 is already a wood chipper knows the knife and knife holder by separate screw ben are attached. A filler in the sense of the invention is not provided there, however.
Auf Grund der erfindungsgemäß vorgesehenen Aufteilung der Mes serbefestigung kann für das Messer ein relativ kleines Befesti gungsglied verwendet werden, während zur Befestigung des Füll stückes ein entsprechend größeres Befestigungsglied dient. Zum Auswechseln des Messers braucht daher nur das (vergleichsweise kleine) erste Befestigungsglied gelöst und wieder angezogen werden, während das von dem zweiten Befestigungsglied gehaltene Füllstück nicht gelöst zu werden braucht. Hierdurch ist das Auswechseln der Messer sehr einfach und kann von nur einer Person durchgeführt werden. Ein weiterer Vorteil der Erfindung besteht darin, daß identische (standardisierte) Messer bzw. Messerkassetten für unterschiedliche Hackscheiben verwendet werden können. Hierzu ist lediglich erforderlich, daß die Füll stücke an die unterschiedlich geformten Hackscheiben angepaßt werden. Die Messer bzw. die Haltekassetten für die Messer kön nen dagegen völlig identisch bleiben. Die standardisierten Mes ser können somit auch bei bereits existierenden Scheiben einge setzt werden.Due to the division of the mes provided according to the invention Ser fastening can be a relatively small fastening for the knife supply member used while attaching the fill piece serves a correspondingly larger fastener. To the Replacing the knife therefore only needs this (comparatively small) first fastener released and tightened again while the one held by the second fastener Filler does not need to be loosened. This is it Changing the knives very easily and can be done by just one Person. Another advantage of the invention consists of identical (standardized) knives or Knife cassettes used for different chopping discs can be. All that is required is that the filling pieces adapted to the differently shaped chopping discs will. The knives or the holding cassettes for the knives can however, remain completely identical. The standardized meas ser can thus be used even with existing disks be set.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unter ansprüchen angegeben.Advantageous embodiments of the invention are in the sub claims specified.
Fig. 1 zeigt einen Längsschnitt durch einen Teil einer Hack scheibe mit einer Messerbefestigung nach einer ersten Ausführungsform. Fig. 1 shows a longitudinal section through part of a chopping disk with a knife attachment according to a first embodiment.
Fig. 2 zeigt einen entsprechenden Schnitt durch eine abgewan delte Ausführungsform. Fig. 2 shows a corresponding section through a modified embodiment.
In der Fig. 1 ist eine Hackscheibe 10 mit einer Öffnung 12 für den Durchgang der Hackspäne dargestellt. Die Hackscheibe 10 hat an einer der neben der Öffnung 12 gelegenen Kante, in der Fig. 1 der linken Kante, eine treppenstufenartige Ausnehmung 14 zur Aufnahme eines Spanführungsteils und einer Messerhalterung. An die Ausnehmung 14 schließt sich ein Verschleißblech 16 an. Eine Anzahl von Öffnungen 12, Ausnehmungen 14 und dahinterliegenden Verschleißblechen 16 sind mit gleichen Zwischenräumen an der Hackscheibe 10 vorgesehen.In FIG. 1, a rotor disc 10 is illustrated with an opening 12 for the passage of the wood chips. The chopping disk 10 has, on one of the edges located next to the opening 12 , the left edge in FIG. 1, a step-like recess 14 for receiving a chip guiding part and a knife holder. A wear plate 16 connects to the recess 14 . A number of openings 12 , recesses 14 and wear plates 16 located behind them are provided with the same spaces on the chopping disk 10 .
In der Ausnehmung 14 ist ein Füllstück 18 eingesetzt, das in der Ausnehmung 14 mittels eines Bolzens 20 gehalten wird, der in das Füllstück 18 eingeschraubt und auf der Unterseite der Hackscheibe 10 mittels einer Mutter 22 festgezogen ist. Dieses Füllstück 18 ist so geformt, daß es in die bereits vorgesehenen Ausnehmungen 14 in der Hackscheibe 10 hineinpaßt. Das Füllstück 18 ist seinerseits an seinem oberen, der Öffnung 12 zugekehrten Teil mit einer Ausnehmung 24 versehen. In diese Ausnehmung 24 ist eine Haltekassette eingesetzt, die aus einem Oberteil 26 und einem Unterteil 28 besteht. Diese Teile sind so geformt, daß sie zwischen sich ein Messer 30 aufnehmen können. In ihrer zusammengefügten Lage, wo das Oberteil 26 und das Unterteil 28 der Haltekassette das Messer 30 zwischen sich aufnehmen, paßt diese Haltekassette in die Ausnehmung 24 des Füllstückes 18. Die Haltekassette weist hierbei durchgehende Löcher für ein von oben eingeschraubtes Befestigungsglied, wie eine Schraube 32, auf, das in das Füllstück 18 eingeschraubt ist. In dieser Lage haben das Oberteil 26 und das Unterteil 28 der Haltekassette einen Spielraum zwischen ihren waagerechten Oberflächen, um durch Anziehen der Schraube 32 eine auf das Messer 30 wirkende Klemmkraft zu erzeugen, die es sicher zwischen dem Oberteil 26 und dem Unterteil 28 der Haltekassette festhält. Um zu verhin dern, daß einzelne Späne von den abgetrennten Holzhackstücken zwischen die Grenzflächen zwischen Messer 30 und Unterteil 28 der Haltekassette sowie zwischen Unterteil 28 und Füllstück 18 und zwischen Füllstück 18 und Hackscheibe 10 eindringen, sind alle diese Teile so angeordnet, daß die Weite der Öffnung 12 treppenstufenförmig abwärts zunimmt, wie bei 34, 36 und 38 in der Fig. 1 gezeigt ist.In the recess 14 , a filler piece 18 is inserted, which is held in the recess 14 by means of a bolt 20 which is screwed into the filler piece 18 and tightened on the underside of the chopping disk 10 by means of a nut 22 . This filler 18 is shaped so that it fits into the recesses 14 already provided in the chopping disk 10 . The filler 18 is in turn provided with a recess 24 on its upper part facing the opening 12 . In this recess 24 , a holding cassette is inserted, which consists of an upper part 26 and a lower part 28 . These parts are shaped so that they can hold a knife 30 between them. In its assembled position, where the upper part 26 and the lower part 28 of the holding cassette hold the knife 30 between them, this holding cassette fits into the recess 24 of the filling piece 18 . The holding cassette here has through holes for a fastening member screwed in from above, such as a screw 32 , which is screwed into the filler piece 18 . In this position, the upper part 26 and the lower part 28 of the holding cassette have a clearance between their horizontal surfaces in order to generate a clamping force acting on the knife 30 by tightening the screw 32 , which holds it securely between the upper part 26 and the lower part 28 of the holding cassette . In order to prevent that individual chips from the separated wood chippings penetrate between the interfaces between knife 30 and lower part 28 of the holding cassette and between lower part 28 and filler 18 and between filler 18 and chopping disk 10 , all these parts are arranged so that the width of the Opening 12 increases downward in a step-like manner, as shown at 34 , 36 and 38 in FIG. 1.
Bei der in der Fig. 2 veranschaulichten Ausführungsform sind die für die beiden Figuren gemeinsamen Teile mit denselben Be zugszeichen wie in der Fig. 1 mit dem Zusatz "a" bezeichnet. Die Hackscheibe 10 a hat eine Ausnehmung 14 a mit lotrechten Wänden. Das Füllstück 18 a besteht aus einem unteren Teil 40, der an dem hinteren Teil der Ausnehmung 14 a der Hackscheibe 10 a angeschweißt ist, und einem oberen Teil 42, der mittels eines Bolzens 20 a festgezogen ist, der durch die Hackscheibe 10 a zu deren Unterseite hindurchgeht, wo der Bolzen 20 a mit Hilfe ei ner Mutter 22 a festgezogen ist. Der obere Teil 42 des Füllstücks 18 a bildet einen Messerhalter und ist mit einer Erhöhung 44 aus gebildet, die in eine entsprechende Ausnehmung in dem Messer 30 a eingreift. Hinter dem Messer 30 a, in der Drehrichtung gesehen, ist der obere Teil 42 mit einem eigenen Verschleißblech 46 ver sehen. Das Messer 30 a und das Verschleißblech 46 sind am oberen Teil 42 von der Oberseite der Hackscheibe 10 a her mit Hilfe von Schrauben 48, 50 festgezogen, derart, daß diese Teile leicht ausgewechselt werden können.In the embodiment illustrated in FIG. 2, the parts common to the two figures are identified by the same reference numerals as in FIG. 1 with the addition "a" . The chopping disk 10 a has a recess 14 a with vertical walls. The filler 18 a consists of a lower part 40 , which is welded to the rear part of the recess 14 a of the chopping disk 10 a , and an upper part 42 , which is tightened by means of a bolt 20 a , through which the chopping disk 10 a Bottom passes where the bolt 20 a is tightened with the aid of a nut 22 a . The upper part 42 of the filler 18 a forms a knife holder and is formed with an elevation 44 , which engages in a corresponding recess in the knife 30 a . Behind the knife 30 a , seen in the direction of rotation, the upper part 42 is seen with its own wear plate 46 ver. The knife 30 a and the wear plate 46 are tightened on the upper part 42 from the top of the chopping disk 10 a by means of screws 48 , 50 , such that these parts can be easily replaced.
