Abstract

Edging-separation devices enable cut remnants (edgings from the main sawn product) to be removed in the wood-working industry. They are used on the cut-out side of wood-working machines. In such devices, it is convenient to design them in such a way that there is no risk of breakdowns, e.g. due to deformation of separator plates, and, at the same time as the edging separation, the main product arriving in both a single bay and a multi-bay on the wood-working machine can be separated into various grades. The invention achieves this object by the use of an adjustable conveyor belt or an adjustable conveyor chain (3) and an adjustable deflector plate (9) or two adjustable deflector plates. <IMAGE>

Description

Technisches Gebiet, auf das sich die Erfindung bezieht:Technical field to which the invention relates:

Die Erfindung bezieht sich auf die Spreißelabscheidung und Hauptwarentrennung für eine Holzverarbeitungsmaschine; dabei wird durch Einsatz eines verstellbaren Kettenzuges zum Abtransport des Holzes, in Verbindung mit einem (oder zwei verstellbaren Abweisblechen gleichzeitig, sowohl eine Hauptwarentrennung, als auch eine Spreißelabscheidung im gleichen Arbeitsgang ermöglicht.The invention relates to the splinter separation and main product separation for a woodworking machine; The use of an adjustable chain hoist to remove the wood, in conjunction with one (or two adjustable baffle plates at the same time, enables both a main product separation and a splinter separation in the same work step.

Einschlägiger Stand der Technik mit Fundstellen:Relevant state of the art with sources:

Spreißelabscheidungseinrichtungen ermöglichen in der holzverarbeitenden Industrie eine Entfernung von Schnittreststücken (Spreißeln) von der gesägten Schnitt-Hauptware. Sie kommen auf der Ausschnittsseite von Holzverarbeitungsmaschinen zum Einsatz.Splinter separation devices enable the removal of cut pieces (splinters) from the sawn cut main goods in the woodworking industry. They are used on the cut-out side of woodworking machines.

Es sind bereits Spreißelabscheidungseinrichtungen bekannt, die mit ein bzw. zwei flexiblen Lamellen arbeiten. Diese Trennlamellen greifen in die Schnittfuge zwischen Hauptware und den Spreißeln ein. Alternativ hierzu werden auch Kettenzüge bzw. Transportbänder verwendet, die die Hauptware führen und transportieren, so daß die Spreißel rechts und links der Hauptware durch ihr Eigengewicht hinunterfallen und so von der Hauptware getrennt werden.Splinter separation devices are already known which work with one or two flexible lamellae. These separating lamellas engage in the kerf between the main goods and the splitters. As an alternative to this, chain hoists or conveyor belts are used to guide and transport the main goods, so that the splitters on the right and left of the main goods fall down due to their own weight and are thus separated from the main goods.

Das zuerst genannte Verfahren mittels Spreißelabscheiderlamellen birgt die Problematik des sicheren Einfädelns der Lamellen in die Schnittfuge. Hier kann es auf Grund der unterschiedlichen Struktur verschiedener Holzarten, so wie deren Zustand, zu Störungen in Form von Klemmen oder Deformation bzw. Beschädigung der Lamellen kommen. Bei dem zweiten Verfahren mittels Transportkette, bzw.-band sind solche Störungen nicht möglich, jedoch ist keine Hauptwarentrennung in Form von Sortierung der verschiedenen Stiele (einzelne Hauptwarenbretter oder -dielen) mit dieser Einricht möglich. Desweiteren ist hier eine Spreißelabscheidung nur für ximal zwei Stiele möglich.The first-mentioned method using a separator lamella has the problem of safely threading the lamella into the kerf. Due to the different structure of different types of wood, such as their condition, there may be faults in the form of clamps or deformation or damage to the slats. Such disturbances are not possible with the second method using a transport chain or belt, however, no main product separation in the form of sorting the different stems (individual main product boards or planks) is possible with this device. Furthermore, splinter separation is only possible for a maximum of two stems.

Darstellung der ErfindungPresentation of the invention

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, auf der Austrittsseite einer Holzverarbeitungsmaschine, die sowohl ein, als auch mehrstielig ankommende Hauptware in einem Arbeitsgang zu sortieren und gleichzeitig von den Spreißeln zu trennen, ohne daß Störmomente in Form von möglichen Deformationen von Spreißelab scheiderlamellen in Kauf genommen werden müssen. Bei der Erfindung kommt nämlich eine Hauptwarentransportkette bzw. ein Hauptwarentransportband in Verbindung mit ein bzw. zwei Spreißelabscheiderblechen zum Einsatz, die durch entsprechende Verstellung die geschilderte Aufgabe lösen. Dadurch werden die bisher bestehenden Unzulänglichkeiten mit Sicherheit ausgeschlossen.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem on the exit side of a woodworking machine that sorts both the single and multi-stemmed incoming goods in one operation and at the same time to separate them from the splitters without disturbing moments in the form of possible Deformation from Spreißelab cutting blades must be accepted. In the invention, namely, a main goods transport chain or a main goods transport belt is used in connection with one or two spreader separator plates, which solve the described task by appropriate adjustment. As a result, the existing shortcomings are definitely excluded.

Vorteilhafte Wirkungen der ErfindungAdvantageous effects of the invention

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß an Stelle von Spreißelabscheiderlamellen, Abweisbleche zum Einsatz kommen, die jeweils dicht unter die Schnittfuge zwischen Hauptware und Spreißeln positioniert werden und somit keine störungsbehaftete Einfädelung notwendig wird, wenn die Spreißel links und rechts der Hauptware - durch ihr Eigengewicht bedingt - auf den steil verlaufenden Abweisblechen in die Spreißelsammelzone herabrutschen.The advantages achieved by the invention are essentially to be seen in the fact that instead of spreader separator lamellas, deflector plates are used, which are positioned closely under the kerf between the main goods and the spreader bars and thus no faulty threading is necessary if the spreader bars are on the left and right the main goods - due to their own weight - slide down on the steep baffles into the chippings collecting zone.

Durch die in der Erfindung zusätzlich vorgesehene Transporteinrichtung mittels Kette, bzw. Band, die unter den gewünschten Stiel, bzw. die gewünschten Stiele der Hauptware positioniert werden kann, ist eine Sortierung der Hauptware in ein, zwei oder drei verschiedene Kategorien möglich, denn der jeweils nicht von der Transporteinrichtung getragene Teil der Hauptware fällt durch sein Eigengewicht auf tiefer liegende Sortierförderer.
Die Erfindung erlaubt somit eine gleichzeitige Hauptwarensortierung sowie Spreißelabscheidung in einem Arbeitsgang.By means of the transport device additionally provided in the invention by means of a chain or belt, which can be positioned under the desired handle or the desired handles of the main goods, the main goods can be sorted into one, two or three different categories, because each Part of the main goods not carried by the transport device falls on lower-lying sorting conveyors due to its own weight.
The invention thus allows a simultaneous main product sorting and splinter separation in one operation.

Durch diese Anordnung ist eine sehr schnelle Schnittfolge möglich, weil die Verstellung der Kette bzw. des Bandes und des Abweisbleches sofort nach Austritt des Schnittgutes erfolgen kann, während bei zweilamelligen Abscheidern erst verstellt werden kann, wenn die Hauptware die Lamellen verlassen hat.With this arrangement, a very quick sequence of cuts is possible because the adjustment of the chain or the belt and the deflector plate can take place immediately after the material to be cut out, while in the case of two-lamellar separators, it can only be adjusted when the main goods have left the lamellae.

Beschreibung wenigstens eines Weges zur Ausführung der Erfindung unter Bezugnahme auf die Zeichnungen.Description of at least one way of carrying out the invention with reference to the drawings.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.

Die Abbildung 1.1 zeigt einen bekannten Spreißelabscheider für ein-stielige Hauptware (1) von der Holzauslaufseite, der mittels Transportband bzw. -kette (3) arbeitet, bei dem die Spreißel (2) rechts und links von der Hauptware durch ihr Eigengewicht herunterfallen. Damit die Hauptware auf dem Transportband bzw. der Transportrolle geführt wird, wird sie von oben im Allgemeinen durch Rollen (4) gehalten.Figure 1.1 shows a known scraper separator for single-stem main goods (1) from the wood outlet side, which works by means of a conveyor belt or chain (3), in which the spreader (2) falls to the right and left of the main goods due to its own weight. So that the main goods are guided on the conveyor belt or the transport roller, they are generally held by rollers (4) from above.

Die Abbildung 1.2 zeigt denselben Spreißelabscheider für zweistielige Hauptware (5).Figure 1.2 shows the same spreader separator for two-tier main goods (5).

Die Abbildung 1.3 zeigt einen weiteren bekannten Spreißelabscheider für ein- und mehrstielige Hauptware (6), bei dem Trennlamellen (7) die Hauptware von den Spreißeln (2) trennen. Hier werden die Spreißel nach rechts und links durch die Trennlamellen weggeschoben. Für den Holztransport sorgen über die gesamte Schnittholzbreite hinausragende Rollen (8).Figure 1.3 shows another known separator for single and multi-stem main goods (6), in which separating lamellae (7) separate the main goods from the spreaders (2). Here the chisels are pushed to the right and left through the separating lamellas. Rollers (8) extend beyond the entire width of the sawn timber for the transport of wood.

Die Abbildung 2.1 zeigt den erfindungsgemäßen Spreißelabscheider, geeignet für ein- und mehrstielige Hauptware (6) (hier sind beispielsweise drei Stiele zu sehen), mit dem darunterliegenden Transportband bzw. der darunterhängenden Transportkette (3) für die Trennung der Hauptware und mit den Abweisblechen (9) für die Abscheidung der Spreißel. Dabei werden ein oder zwei Stiele zwischen den obenliegenden Andruckrollen (4) und dem darunter befindlichen Transportband oder der darunterliegenden Transportkette (3) gehalten und dabei einer bestimmten Sortierstelle zugeführt. Die restlichen Stiele (hier in der Abbildung 2.1 rechts davon) fallen durch ihr Eigengewicht auf das darunterliegende Förderband (10), und können somit einer anderen Sortierstelle zugeführt werden. Die beiden Spreißel (2) rechts und links der Hauptware rutschen durch ihr Eigengewicht auf den steil angeordneten Trennblechen herab und können in die Sortierstelle für Spreißel eingebracht werden.Figure 2.1 shows the splinter separator according to the invention, suitable for single and multi-stemmed main goods (6) (here, three stems can be seen for example), with the conveyor belt underneath or the transport chain underneath (3) for separating the main goods and with the deflector plates ( 9) for the separation of the splinters. One or two stems are held between the pressure rollers (4) on top and the conveyor belt or conveyor chain (3) underneath and are fed to a specific sorting point. The remaining stems (here on the right in Figure 2.1) fall due to their own weight onto the conveyor belt (10) underneath, and can therefore be fed to another sorting point. The two splitters (2) to the right and left of the main goods slide down on the steeply arranged dividers due to their own weight and can be inserted into the sorting point for splitters.

Sollen in einer Sonderanwendung alle Stiele der Hauptware in (hier in Abb. 2.1 nach rechts) das darunterliegende Förderband (10) eingebracht werden, so sorgt ein keilförmiger, einschwenkbarer Abweiser (11) (siehe Abb. 2.2) dafür, daß auf die Stiele, die sich zwischen den obenliegenden Andruckrollen (4) und dem darunter befindlichen Transportband, bzw. der darunter befindlichen Transportkette (3) (in diesem Fall in Abb. 2.1 nach rechts) in das unten befindliche Transportförderband fallen können. Dabei sind sowohl die Transportkette bzw. das Transportband (3), als auch die Abweisbleche (9) seitlich verschiebbar (siehe Doppelpfeile in Abb. 2.3), so daß die Spreißel und die Hauptware unabhängig von der Anzahl der Stiele und deren Breite immer in die richti Klassifizierungsstellen fallen bzw. transportiert werden können.If, in a special application, all stems of the main goods are to be inserted into the conveyor belt (10) below (here in Fig.2.1 to the right), a wedge-shaped, swiveling deflector (11) (see Fig.2.2) ensures that the stems, that can fall between the pressure rollers (4) on top and the conveyor belt underneath or the conveyor chain (3) underneath (in this case to the right in Fig. 2.1) into the conveyor belt below. Both the transport chain or the conveyor belt (3) and the deflector plates (9) can be moved laterally (see double arrows in Fig.2.3), so that the spreader and the main goods are always in regardless of the number of stems and their width correct classification points fall or can be transported.
