Description
Die Erfindung betrifft einen Zerspaner zum Herstellen von Spänen, insbesondere für die Spanplattenindustrie.The invention relates to a chipper for producing chips, especially for the chipboard industry.
Eine besonders verbreitete Gattung eines solchen Zerspaners ist der Messerringzerspaner (vgl. DE 32 47 629 C1). Messerringzerspaner sind in einer großen Vielfalt von Bauarten bekannt geworden. Sie weisen einen Messerring auf, umfassend zahlreiche Messereinheiten, die jeweils einen Tragklotz sowie ein von diesem getragenes Messer umfassen. Der Messerring umschließt einen Rotor, der die zu zerspanenden Hackschnitzel dem Messerring radial von innen nach außen zufördert. Der Messerring ist seinerseits von einem Gehäuse umschlossen.A particularly widespread type of such a chipper is the Knife ring chipper (see DE 32 47 629 C1). Knife ring chippers are in a wide variety of designs have become known. You assign one Knife ring on, comprising numerous knife units, each one Include support block and a knife carried by this. The knife ring encloses a rotor that removes the wood chips to be machined Knife ring fed radially from the inside to the outside. The knife ring is in turn enclosed by a housing.
Die Messer des Messerrings verlaufen im wesentlichen parallel zur Messerringachse. Zwischen einem jeden Messer und der benachbarten Messereinheit befindet sich ein Spalt, durch den die Späne radial nach außen treten. Die Tragklötze weisen auf ihrer dem Rotor zugewandten Seite jeweils eine Verschleißfläche auf.The knives of the knife ring run essentially parallel to Knife ring axis. Between each knife and the neighboring one Knife unit is a gap through which the chips radially outwards to step. The support blocks each have on their side facing the rotor a wear surface.
Weiterhin sind Messerwellenzerspaner bekannt. Diese weisen eine Messerwelle mit Messern auf. Die Messer sind ebenfalls über den Umfang der Messerwelle verteilt angeordnet, weisen jedoch mit ihren Schneiden nach außen (vgl. DE 30 18 110 A1).Knife shaft chippers are also known. These have a Knife shaft with knives on. The knives are also about the scope of the Knife shaft arranged in a distributed manner, but with their cutting edges outside (cf. DE 30 18 110 A1).
Allen diesen Zerspanern ist gemeinsam, daß sie Zuführorgane für das zu zerspanende Gut haben. So ist beim Messerringzerspaner dem Messerring zunächst eine Vibrationsförderstrecke zugeordnet, an die sich eine Fallstrecke anschließt. Die Fallstrecke kann Leitbleche aufweisen, die das zu zerspanende Gut auf einem Zickzack-Weg leiten. All these chippers have in common that they have feeders for the have good machining. So is the knife ring with the knife ring chipper First of all, a vibration conveyor section is assigned to which there is a drop section followed. The fall path can have baffles that are to be machined Guide well on a zigzag path.
Bei allen Zerspanern besteht das Bedürfnis, den Durchsatz des zu zerspanenden Gutes, d.h. die pro Zeiteinheit durchgesetzte Menge zu erfassen.With all hoggers there is a need to increase the throughput of the good, i.e. the amount enforced per unit of time to capture.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, mit der es möglich ist, den Durchsatz oder die Mengenleistung eines Zerspaners zu jedem beliebigen Zeitpunkt zu erfassen, und zwar möglichst die Menge des absolut trockenen Gutes.The invention has for its object to provide a device with which is possible the throughput or the volume output of a chipper to be recorded at any time, if possible the quantity of the absolutely dry good.
Diese Aufgabe wird durch Merkmale von Anspruch 1 gelöst.This object is achieved by the features of claim 1.
Die Erfinder haben demgemäß eine verblüffend einfache Maßnahme ergriffen. Sie haben eine Dehnungsmeßeinrichtung in den Förderweg des zu zerspanenden Gutes eingebaut. Die Dehnungsmeßeinrichtung greift dabei einerseits an einem Bauteil an, auf welches der Gutstrom aufprallt, und zum anderen an einem starren Bauteil des Maschinengestells. Beim Aufprall des Gutstromes erfährt die Dehnungsmeßeinrichtung eine Längung. Das Maß der Längung hängt ab von der Intensität des Aufpralles, die wiederum eine Funktion der aufprallenden Masse sowie deren Geschwindigkeit ist. Somit läßt sich zu jedem Zeitpunkt der Durchsatz erfassen. Darüber hinaus kann man durch mathematische Integration die Gesamtmenge des Gutes ermitteln, das während einer bestimmten Zeitspanne in den Arbeitsbereich der Maschine eintritt.The inventors have accordingly taken an amazingly simple measure. You have a strain gauge in the conveying path of the metal-cutting goods. The strain gauge intervenes on the one hand on a component to which the material flow impinges, and on another on a rigid component of the machine frame. When the Gutstromes the strain gauge is elongated. The measure of Elongation depends on the intensity of the impact, which in turn is one The function of the impacting mass and its speed is. Thus leaves record throughput at all times. In addition, you can determine the total amount of the good by mathematical integration during a certain period of time in the working area of the machine entry.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im einzelnen folgendes dargestellt:
- Fig. 1
- zeigt einen Zerspaner von vorn, d.h. in einer Ansicht auf diejenige Seite, auf der sich der Gehäusedeckel mit dem Einlaß für die Hackschnitzel befindet.
- Fig. 2
- zeigt den Zerspaner gemäß Figur 1 in vergrößertem Maßstab in einem Axialschnitt.
- Fig. 3
- zeigt in vergrößertem Maßstab den Einlaß für die zu zerspanenden Hackschnitzel.
- Fig. 1
- shows a chipper from the front, ie in a view of the side on which the housing cover with the inlet for the chips is located.
- Fig. 2
- shows the chipper according to Figure 1 in an enlarged scale in an axial section.
- Fig. 3
- shows on an enlarged scale the inlet for the wood chips to be cut.
Wie man aus den Figuren im einzelnen sieht, weist der Zerspaner einen
ringförmigen Messerkorb 1 auf. Dieser ist umschlossen von einem Gehäuse 2,
und umschließt seinerseits einen Rotor 3. Der Messerkorb 1 ist aufgebaut aus
zwei Ringen 1.1 und 1.2, ferner aus Messereinheiten.As you can see from the figures in detail, the chipper has one
ring-shaped knife basket 1. This is enclosed by a
Das Gehäuse 2 weist einen Einlaß 2.1 für die zu zerspanenden Hackschnitzel
auf, ferner einen Ringkanal 2.2, in dem die Späne gesammelt und aus dem
sie abgeführt werden.The
Entscheidend für die Erfindung ist die Gestaltung des Einlasses 2.1 sowie einer darin vorgesehenen Dehnungsmeßeinrichtung. Der in Figur 3 genauer dargestellte Einlaß 2.1 weist als Leitorgane Prallplatten 2.1.1, 2.1.2 und 2.1.3 auf. Diese leiten das zu zerspanende Gut entlang eines Zickzack-Weges - siehe gestrichelte Linie mit Pfeilen.Decisive for the invention is the design of the inlet 2.1 and a strain gauge provided therein. The one in Figure 3 in more detail Inlet 2.1 shown has baffles 2.1.1, 2.1.2 and 2.1.3 as guide elements on. These guide the material to be cut along a zigzag path - see dashed line with arrows.
Man erkennt eine Dehnungsmeßeinrichtung 4. Diese umfaßt eine Konsole 4.1
sowie einen Dehnungsmeßstreifen 4.2. Die Konsole 4.1 ist an einer
Wandung 2.5 des Einlasses 2.1 fest angeschweißt. Das freie Ende der
Konsole 4.1 stützt die obere Prallplatte 2.1.1 ab. Die obere Prallplatte 2.1.1 ist
ausschließlich von der Dehnungsmeßeinrichtung 4 getragen. Sie könnte an
dieser gelenkig angeschlossen sein.A
Der Dehnungsmeßstreifen 4.2 ist einerseits an der starren Wandung 2.5 des Einlasses 2.1 befestigt, andererseits an der oberen Prallplatte 2.1.1. Die obere Prallplatte 2.1.1 erfährt durch den Aufprall des Gutstromes eine Durchbiegung, so daß der Dehnungsmeßstreifen 4.2 eine entsprechende Verkürzung oder Längung ausführt.The strain gauge 4.2 is on the one hand on the rigid wall 2.5 of the Inlet 2.1 attached, on the other hand to the upper baffle 2.1.1. The upper Baffle plate 2.1.1 experiences a through the impact of the material flow Deflection so that the strain gauge 4.2 has a corresponding Shortening or elongation.
Eine hier nicht dargestellte Einrichtung zum Erfassen der Feuchte des Gutstromes erlaubt die Umrechnung der pro Zeiteinheit durchgesetzten Menge des Gutes in absoluten Gewichtswerten, d.h. frei von Feuchtigkeit. Eine solche Einrichtung arbeitet berührungslos, beispielsweise nach dem Prinzip der Induktivität.A device, not shown here, for detecting the moisture of the Gutstromes allows the conversion of those implemented per unit of time Quantity of the goods in absolute weight values, i.e. free of moisture. Such a device works without contact, for example after Principle of inductance.
