Abstract

A wood cutting machine having a knife-like blade for cutting and chipping wood into large pieces. The blade is oriented at an angle to the direction of wood grain thereby lowering the force required to cut the wood.

Description

Die Erfindung betrifft eine Zerkleinerungsmaschine für länqliche Holzstücke, z.B. Holzbalken oder Baumstämme, bei der an einem stoßweise vorschiebbaren Schlitten ein Messer mit quer zur Holzfaserrichtung lieaender Schneide angeordnet ist.The invention relates to a shredding machine for elongated pieces of wood, e.g. Wooden beams or tree trunks, in which a knife with a cutting edge that is transverse to the wood fiber direction is arranged on a slide that can be pushed forward intermittently.

Derartige Maschinen zerteilen das Schnittgut in mehr oder weniger große Stücke quer zur Faserrichtung. Die bisher bekannten und im Handel erhältlichen Maschinen haben jedoch den Nachteil, daß ihr Kraftbedarf sehr hoch ist und daß die quer abgeteilten Holzstücke nicht in Faserrichtung aufgespalten sind.Such machines cut the clippings into more or less large pieces across the grain. The previously known and commercially available machines, however, have the disadvantage that their power requirement is very high and that the transverse pieces of wood are not split in the direction of the fibers.

Der Erfindung liegt die Aufgabe zu Grunde, eine Holzbalken-Zerkleinerungsmaschine mit erheblich geringerem Kraftbedarf aufzuzeigen, welche zudem die abgteilten Holzstücke bei Bedarf auch in Faserrichtung aufspaltet.The invention is based on the object of demonstrating a wooden beam comminution machine with considerably less power, which also splits the divided pieces of wood in the direction of the fibers if necessary.

Diese Aufgabe wird nach dem Anspruch 1 dadurch gelöst, daß der Schlitten in seinem oberen Teil pendelnd aufgehängt ist und daß der Anstellwinkel der dem einlaufenden Schnittgut zugekehrten, nicht angeschärften Fläche des Messers zum Boden eines dieses Schnittqut führenden Kanals bis zum Beginn des Schneidvorgangs unter dem Einfluß der Schwerkraft durch eine erste, auf der Holzeinlaufseite befindliche Stelleinrichtunn auf 50° bis 80°, vorzugsweise auf 65° bis 70°, nach oben zu und ggfs. der Anstellwinkel beim Schneidvorgang selbst unter dem Einfluß des Schneidwiderstands durch eine unterhalb auf der Holzauslaufseite befindliche zweite Stelleinrichtung auf etwa 45° nach unten zu begrenzt wird. Dadurch, daß das Messer zunächst unter dem Einfluß der Schwerkraft mit großem Anstellwinkel am Schnittnut angreift und erst dann, nämlich nach einem selbsttätigen Schwenken des Schlittens unter dem Einfluß des Schneidwiderstands den eigentlichen Schneidvorgang mit geringerem Anstellwinkel durchführt, tritt eine erhebliche Kraftersparnis ein, die bis zu 60% betragen kann. Für stark asthaltiges Holz werden große und für Hartholz kleine Anstellwinkel im Rahmen der vorstehend angegebenen Bereiche angewandt. Zur Anoassung sind jene Stelleinrichtungen verstellbar ausgebildet.This object is achieved according to claim 1 in that the sled is suspended in its upper part and that the angle of attack of the non-sharpened surface of the knife facing the incoming clippings to the bottom of a channel leading this clippings channel until the beginning of the cutting process under the influence gravity by a first actuator located on the wood inlet side to 50 ° to 80 °, preferably 65 ° to 70 °, and possibly the angle of attack during the cutting process itself under the influence of the cutting resistance by a second one located below on the wood outlet side Actuator is limited to about 45 ° down. Because the knife first acts under the influence of gravity with a large angle of attack on the cutting groove and only then, namely after an automatic swiveling of the slide under the influence of the cutting resistance, does the actual cutting process with a smaller angle of attack, a considerable saving in force occurs, which can be up to Can be 60%. For wood with strong knots, large angles of attack for hardwood are used within the ranges specified above. For adjustment purposes, those adjusting devices are adjustable.

Um besonders zähe Holzstücke in Faserrichtunq aufzuspalten, ist wenigstens ein Spaltmesser am Schneidmesser in jeweils einer zu diesem rechtwinkligen und zum Schneidgut hin gerichteten Ebene angeordnet.In order to split particularly tough pieces of wood in the direction of fibers, at least one splitting knife is arranged on the cutting knife in each case in a plane perpendicular to the latter and directed towards the material to be cut.

Vorteilhaft ist das Messer über ein gleichsinnig abgeschrägtes Keilstück am Schlitten auswechselbar befestigt; der Keilwinkel des Messers liegt dabei zwischen 20° und 40° und der des Keilstücks bei etwa 45°. Die Holzteile werden dadurch so starken Zugspannungen ausgesetzt, daß sie quer zur Faserrichtung aufbrechen, was das Trocknen und die Handhabung beim Heizen fördert.The knife is advantageously fastened interchangeably to the slide by means of a wedge piece which is beveled in the same direction; the wedge angle of the knife is between 20 ° and 40 ° and that of the wedge piece is about 45 °. The wooden parts are exposed to such strong tensile stresses that they break open transversely to the grain, which promotes drying and handling during heating.

Zur Belegung des pendelnd aufgehängten, mit einem Schneidmesser versehenen Schlittens kann ein vorzugsweise verstellbares Kurbelgetriebe, ggfs. mit Untersetzungsgetriebe, verwendet werden.A preferably adjustable crank gear, possibly with a reduction gear, can be used to occupy the pendulum-suspended carriage provided with a cutting knife.

Es kann dazu aber auch eine Hydraulikzylinder-Kolben-Einheit verwendet werden; der Schlitten wird dann vorteilhaft über ein Gleitfuhrungsstück nendelnd aufgehängt. Ferner kann dann am Schlitten eine Stanae parallel befestigt sein, die je einen Anschlag für den oberen bzw. unteren Totnunkt der Schlittenbewegung trägt: am Gleitführunasstück ist dabei ein von diesen Anschlägen mechanisch steuerbares Hydraulikventil angebracht, das durch eine Feder in der ge-wählten Stellunq gehalten wird. Beim Anhebvorgang des Schlittens samt Messer schwenkt das Gleitführungsstück bis zum Anschlagen an die erste, also obere Stelleinrichtung zurück, sobald sich das Messer aus dem Schnittnut herausbeweot hat. Beim Absenkvorgang greift das Messer zunächst mit ziemlich großem Anstellwinkel eine gewisse Länge vor dem Ende des Schnittguts an und schiebt dieses so weit vor, bis das Gleitführungsstück an der zweiten, also unteren Stelleinrichtung anschlänt. Von da ab wird geschnitten, und zwar mit kleinerem Anstellwinkel.A hydraulic cylinder / piston unit can also be used for this; the slide is then advantageously suspended by a sliding guide piece. Furthermore, a stanae can then be fastened in parallel on the slide, each bearing a stop for the upper and lower dead center of the slide movement: there is on the sliding guide piece mounted in a mechanically controllable by these attacks hydraulic valve, the selected e-by a spring in the g Stellunq is maintained. During the lifting process of the slide together with the knife, the sliding guide piece swings back until it strikes the first, that is to say upper, control device as soon as the knife has moved out of the cutting groove. During the lowering process, the knife first engages with a fairly large angle of attack a certain length before the end of the clippings and pushes them forward until the sliding guide piece snakes on the second, ie lower, adjusting device. From there, the cut is made with a smaller angle of attack.

Je weiter das Gleitführungsstück samt Schlitten und Messer zurückoendelt, deso dicker werden die abgeschnittenen Holzstücke: diese Dicke kann also durch jene beiden Stelleinrichtungen eingestellt werden; sie wird umso geringer, je dicker das Schnittgut ist. Wenn man eine einheitliche Dicke der Holzstücke erreichen will, wird am hinteren Ende des Schnittgutkanals ein einstellbarer Anschlag für den unteren Ouerschnittsteil des Schnittguts angebracht; die zweite, untere Stelleinrichtung wird dann gafs. überflüssig.The further back the slideway piece, including the slide and knife, the thicker the cut pieces of wood become: this thickness can therefore be adjusted using these two adjusting devices; it gets smaller the thicker the clippings. If you want to achieve a uniform thickness of the pieces of wood, an adjustable stop is attached to the lower end of the clippings at the rear end of the clippings channel; the second, lower setting device is then gafs. superfluous.

Zwecks Verbesserung der Schnittgut-Zuführung kann der Schnittgutkanal in Transportrichtung trichterförmig verennt ausnebildet sein. Um mehrere dünne Schnittgutteile nebeneinander verarbeiten zu können, wird der Boden des Schnittgutkanals zu seiner Querschnittsmitte hin muldenförmig vertieft ausgebildet: zur weiteren Verbesserung dienen schräg stehende Bleche, welche die unteren Ecken des Schnittgutkanals überdecken. Ein ungewolltes Zurückschieben des Schnittguts kann dadurch verhindert werden, daß an der Decke des Schnittgutkanals innen Zacken oder scharfkantioe Klappen schwenkbar angebracht sind, die in das Schnittgut oben etwas eindrinnen; auch kann der Boden des Schnittgutkanals in Transportrichtung stufen- oder sägezahnförmig abfallend ausgebildet sein. Schließlich können am Roden des Schnittgutkanals an seinem hinteren Ende Tragrollen angebracht sein, auf denen das Schnittgut vor Beginn des Schneidvorgangs durch das Messer vorgeschoben wird.In order to improve the supply of clippings, the clippings channel can be designed to be funnel-shaped in the transport direction. In order to be able to process several thin clippings next to each other, the bottom of the clippings channel is recessed in the shape of a trough towards its cross-section center: sloping plates that cover the lower corners of the clippings channel are used for further improvement. An unintentional pushing back of the clippings can be prevented by pivoting peaks or sharp-edged flaps on the inside of the clippings duct, which slightly penetrate into the clippings above; also the bottom of the clippings channel in the transport direction should be stepped or sawtooth-shaped. Finally, support rollers can be attached to the clearing of the clippings channel at its rear end, on which the clippings are pushed by the knife before the cutting process begins.

Das Ende der Absenkbewegung wird einstellbar ausgebildet, um den Messerverschleiß ausgleichen zu können. Die Umsteuerung der Schlittenbewegung vom Anheben zum Absenken erfolgt dann, wenn das untere Ende des Schlittens die erste, obere Stelleinrichtung überfahren hat.The end of the lowering movement is designed to be adjustable in order to compensate for knife wear. The reversal of the carriage movement from lifting to lowering takes place when the lower end of the carriage has passed over the first, upper actuating device.

Gemäß Fig. 1 und la ist am Ende eines Transoortkanals 9 für das Schnittgut 8 oben ein Gleitführungsstück 6 für einen Schlitten 5 pendelnd aufgehängt, der über ein Keilstück 2 ein Schneidmesser 1 mit quer zur Holzfaserrichtung liegender Schneide trägt. Dieser Schlitten ist durch eine Hydraulikzylinder-Kolben-Einheit 4 stoßweise vorschiebbar. In angehobenem Zustand nimmt der Schlitten unter dem Einfluß der Schwerkraft durch Anlaae des Gleitführungsstücks an eine erste, auf der Holzeinlaufseite befindliche verstellbare Stelleinrichtung 7 einen ziemlich großen Anstellwinkel α1 zum Schnittnutkanal ein, mit dem das Messer auch beim Absenken am Schnittqut oben angreift und dieses dann vorwärts schiebt; unter dem Einfluß des Schneidwiderstands qe- lanqt der Schlitten sodann durch Anlage des Gleitführungsstücks an eine unterhalb der ersten auf der Holzauslaufseite befindliche zweite Stelleinrichtung 10 in eine Lage mit wesentlich gerinoerem Anstellwinkel α2, mit dem bis zum Boden des Kanals geschnitten wird, worauf die Anhebbewegung einsetzt. Eine erneute Ahsenkbewegung setzt ein, sobald das untere Schlittenende die erste, obere Stelleinrichtung 7 erreicht hat.1 and 1 a, at the end of a transoort channel 9 for the clippings 8, a sliding guide piece 6 for a carriage 5 is suspended, which carries a cutting knife 1 with a cutting edge lying transversely to the wood fiber direction via a wedge piece 2. This slide can be pushed forward in steps by a hydraulic cylinder-piston unit 4. In an lifted state, the slide under the influence of gravity by contact of the sliding guide piece on a first, on the wood inlet side adjustable adjusting device 7 a rather large angle of attack α 1 to the cut groove channel, with which the knife acts on the cut groove even when lowering and this then forward pushes; under the influence of the cutting resistance qelan q t the slide then by contacting the sliding guide piece with a second adjusting device 10 located below the first on the wood outlet side into a position with a substantially lower angle of attack α 2 , with which cutting is made to the bottom of the channel, whereupon the lifting movement begins. A new axis movement begins as soon as the lower slide end has reached the first, upper adjusting device 7.

Messer 1 und Keilstück 2 sind gleichsinnig an der Holzauslaufseite abgeschrägt. Am Messer ist in einer zu ihm rechtwinkligen und zum Schnittgut hin gerichteten Ebene ein Spaltmesser 3 angebracht.Knife 1 and wedge piece 2 are beveled in the same direction on the wooden outlet side. A splitting knife 3 is attached to the knife in a plane perpendicular to it and directed towards the clippings.

Gemäß Fig. 2 ist am im Führungsstück gleitbar angeordneten Schlitten 5 einer derartinen Zerkleinerungsmaschine eine Stange 16 oarallel befestigt: sie trägt je einen Anschlag 17, 18 für den oberen bzw. unteren Totpunkt der Schlittenbewegung. Am Gleitführunnsstück ist ein von diesen Anschlä- gen mechanisch steuerbares Ventil 19 für die Hydraulikzylinder-Kolben-Einheit angebracht, das durch eine Feder 20 in der gewählten Stellung A oder ß gehalten wird.According to FIG. 2, a rod 16 is fastened on the slide 5 of such a shredding machine which is slidably arranged in the guide piece: it carries a stop 17, 18 for the top and bottom dead center of the slide movement. On a Gleitführunnsstück g of this Anschlä- en mechanically controllable valve 19 is mounted for the hydraulic cylinder-piston unit, which is held by a spring 20 in the selected position A or ß.

An der Decke des Transportkanals 9 sind innen scharfkantige Klapoen 12 schwenkbar angebracht, die ein Zurückschieben des Schnittguts 8 verhindern. Der Boden dieses Kanals weist an seinem hinteren Ende Tragrollen 14 für das Schnittgut 8 auf.On the ceiling of the transport channel 9, sharp-edged Klapoen 12 are pivotally attached, which prevent the clippings 8 from being pushed back. The bottom of this channel has support rollers 14 for the clippings 8 at its rear end.

Die Hubbewegung des Schlittens kann dazu benutzt werden, um z.B. mittels einer Ratsche weiteres Schnittgut an die Zerkleinerungsmaschine heranzuführen. Bei großen Bäumen wird zweckmäßig vor dem Transportkanal 9 eine klappbare Rampe 21 vorgesehen, die mittels eines Beins 22 aufgestellt werden kann.The lifting movement of the slide can be used to e.g. to bring further clippings to the shredding machine with a ratchet. In the case of large trees, a foldable ramp 21 is expediently provided in front of the transport channel 9, which ramp can be set up by means of a leg 22.

Gemäß Fig.3 ist zur Bewegung des pendelnden Schlittens 5 ein Kurbelgetriebe 24 angebracht, das über ein Untersetzunsgetriebe 25 angetrieben wird. Statt einer unteren Stelleinrichtung 10 ist hier am hinteren Ende des Transportkanals 9 ein einteilbarer Anschlag 23 für den unteren Querschnittsteil des Schnittquts R angebracht, der eine gleichmäßige Dicke der abgeschnittenen Holzteile gewährleistet. Der Boden des Transportkanals weist in Transportrichtung abfallende sägezahnförmige Stufen 13 auf, welche den Vorschub des Schnittguts 8 fördern.According to FIG. 3, a crank mechanism 24, which is driven by a reduction gear 25, is attached to the movement of the oscillating carriage 5. Instead of a lower actuating device 10, an adjustable stop 23 for the lower cross-sectional part of the cut R is attached to the rear end of the transport channel 9, which ensures a uniform thickness of the cut wooden parts. The bottom of the transport channel has sawtooth-shaped steps 13 sloping in the transport direction, which promote the feed of the clippings 8.
