Abstract

The invention relates to a method and a device for loading a device for eccentrically slicing veneering. Known slicing devices are problematic in that the process for loading the same with a block of wood is relatively time-consuming and at least partly difficult to perform. The aim of the invention is thus to improve one such slicing device in such a way that the loading process is simplified and accelerated. To this end, a device for milling (2) grooves (3) comprises a measuring device (14) which is used to determine the cross-section of the block of wood (4); the position of the grooves (3) and the cross-section of the block of wood (4) can be recorded as data; and a grip device (17) and a tool carriage (5) of the slicing device (1) can be controlled according to the data in such a way that the block of wood (4) can be placed in the slicing device (1) and the tool carriage (5) is positioned in relation to the block of wood (4) in a starting position for the slicing. The invention also relates to the production of veneering.

Description

Beschickung einer Furniermessermaschine Loading a veneer knife machine
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Beschicken einer Vorrichtung zum exzentrischen Schneiden von Furnieren aus einem Holzblock gemäß dem Oberbegriff des Anspruchs 1. Vorrichtungen zum exzentrischen Schneiden, auch Staylog- Messermaschinen genannt, werden eingesetzt, um von einem Holzblock dünne Tafeln, die auch Furniere genannt werden, abzuschneiden.The invention relates to a method and a device for loading a device for eccentric cutting of veneers from a block of wood according to the preamble of claim 1. Devices for eccentric cutting, also called Staylog knife machines, are used to make thin sheets of a block of wood, which also Veneers are called to cut off.
Bei den Staylog- Messermaschinen wird der Holzblock auf einer durch eine ebene Mantelfläche gebildeten Auflagefläche einer Balkenkonstruktion eingespannt. Diese ist um ihre horizontale Längsachse drehbar gelagert, so dass mit jeder Drehbewegung ein Furnier mit einem parallel oder in einem spitzen Winkel zu der Längsachse gelagerten und auf die Balkenkonstruktion zu bewegbaren Messer abgeschnitten wird. Eine solche Messermaschine ist z.B. aus der DE 102 61 918 C bekannt.With the Staylog knife machines, the block of wood is clamped on a support surface of a beam construction formed by a flat outer surface. This is rotatably mounted about its horizontal longitudinal axis, so that with each rotary movement a veneer is cut off with a knife mounted parallel or at an acute angle to the longitudinal axis and movable towards the beam construction. Such a knife machine is e.g. known from DE 102 61 918 C.
Nach dem Beenden eines Messervorgangs ist es relativ arbeits- und zeitaufwändig, einen neuen Holzblock einzuspannen. Hierfür muss der Holzblock, in den in eine Längsseite schmale Nuten eingefräst sind, mit Hilfe z.B. eines Hakengehänges über die Auflagefläche und mit den Nuten zu Halteklauen gebracht werden, Das Spiel zwischen den Halteklauen und den Wänden der Nuten ist sehr klein, so dass das Einspannen eines schweren, langen Holzblocks schwierig ist und entsprechend viel Zeit erfordert.After finishing a knife process, it is relatively laborious and time-consuming to clamp a new block of wood. For this, the block of wood, into which narrow grooves are milled into one long side, must be e.g. of a hook sling over the support surface and with the grooves to the holding claws. The play between the holding claws and the walls of the grooves is very small, so that clamping a heavy, long wooden block is difficult and accordingly takes a lot of time.
Weiterhin muss das Messer in Arbeitsposition gefahren werden. Hierfür muss der Werkzeugschlitten so weit in Richtung des Holzbalkens gefahren werden, dass das Messer knapp nicht den Holzblock berührt.The knife must also be moved to the working position. To do this, the tool slide must be moved so far in the direction of the wooden beam that the knife barely touches the wooden block.
Aufgabe der Erfindung ist es, das Beschicken einer Messermaschine zu vereinfachen und die Rüstzeit, das ist die Zeit vom Ende eines Messervorgangs bis zum Beginn des folgenden, zu verkürzen.The object of the invention is to simplify the loading of a knife machine and to shorten the set-up time, that is the time from the end of a knife operation to the beginning of the following one.
Die Aufgabe ist durch die kennzeichnenden Merkmale der unabhängigen Ansprüche 1 beziehungsweise 2 gelöst. Dadurch, dass in einer Vorrichtung zum Fräsen der Querschnitt des Holzblock bestimmt wird, dass als Daten die Lage der Nuten und der Quer- schnitt des Holzblocks erfasst werden und dass mit Hilfe der Daten der Holzblock in die Vorrichtung eingebracht und ein Messer in eine Startposition gefahren wird, muss das Bedienpersonal den Holzblock nur vor dem Fräsen manipulieren und ist von den weite- ren, teilweise körperlich schweren Arbeiten mit dem Holzblock entlastet. Hierdurch kann sich das Bedienpersonal besser auf das eigentliche Messern konzentrieren, was sich positiv auf die Qualität der Furniere auswirkt.The object is achieved by the characterizing features of independent claims 1 and 2, respectively. The fact that the cross-section of the wooden block is determined in a device for milling, that the position of the grooves and the cross-section of the wooden block are recorded as data, and that the wooden block is inserted into the device with the aid of the data and a knife is moved into a starting position the operator only has to manipulate the block of wood before milling and is work, which is sometimes physically difficult, with the wooden block. This allows the operating personnel to concentrate better on the actual knives, which has a positive effect on the quality of the veneers.
Weiterhin wird die Zeit für das Beschicken und Anfahren um bis 70 % reduziert und die Produktivität der Messermaschine entsprechend erhöht.Furthermore, the time for loading and starting is reduced by up to 70% and the productivity of the knife machine is increased accordingly.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung.The subclaims relate to the advantageous embodiment of the invention.
Die Erfindung wird anhand eines in der Zeichnung schematisch dargestellten Beispiels weiter erläutert. Es zeigenThe invention is further explained using an example shown schematically in the drawing. Show it

Figur 2 eine Seitenansicht senkrecht zu der Ansicht nach Figur 1 auf die Beschik- kungsvorrichtung, teilweise geschnitten.FIG. 2 shows a side view, perpendicular to the view according to FIG. 1, of the charging device, partly in section.
Wie aus Figur 1 ersichtlich, sind eine Vorrichtung zum exzentrischen Schneiden von Furnieren 1 , kurz Staylog- Messermaschine 1 auf einem Grundrahmen, und eine her- kömmliche Vorrichtung zum Fräsen 2 von Nuten 3 in einen Holzblock 4 benachbart aufgestellt.As can be seen from FIG. 1, a device for eccentric cutting of veneers 1, in short Staylog knife machine 1, is placed on a base frame, and a conventional device for milling grooves 2 into a wooden block 4 is placed adjacent.
Die Staylog- Messermaschine 1 umfasst in bekannter Weise einen Werkzeugschlitten 5 und eine Staylog- Balkenanordnung 6. Der Werkzeugschlitten 5 mit einem Messer 8 ist in einer horizontalen Ebene hin und her beweglich gelagert, wie durch einen Pfeil 7 symbolisiert. Die Staylog- Balkenanordnung 6 ist so auf dem Grundrahmen befestigt, dass eine horizontale Längsachse ihrer Balkenkonstruktion 9 parallel zum Messer 8 verläuft. Auf einer durch eine ebene Mantelfläche gebildeten Auflagefläche 10 der Balkenkonstruktion 9 ist der Holzblock 4.a einspannbar.The Staylog knife machine 1 comprises, in a known manner, a tool slide 5 and a Staylog bar arrangement 6. The tool slide 5 with a knife 8 is movably mounted to and fro in a horizontal plane, as symbolized by an arrow 7. The Staylog beam arrangement 6 is fastened to the base frame in such a way that a horizontal longitudinal axis of its beam construction 9 runs parallel to the knife 8. The wooden block 4.a can be clamped on a support surface 10 of the beam construction 9 formed by a flat lateral surface.
Vom Werkzeugschlitten 5 aus gesehen hinter der Staylog- Balkenanordnung 6 ist die Vorrichtung zum Fräsen 2 mit zwei antreibbaren Fräswerkzeugen 13 auf Schienen gelagert, wobei sie parallel zu der Balkenkonstruktion 9 verfahrbar ist. Ein Tisch 11 ist so zu dem Fahrweg der Vorrichtung zum Fräsen 2 angeordnet, dass sich seine obere Tischebene 12 entsprechend der Tiefe der Nuten 3 unterhalb der obersten Begrenzung der Fräswerkzeuge 13 befindet. In die Tischebene 12 ist parallel und vorzugsweise symmetrisch zur Längsachse eine Aussparung eingelassen, so dass die Fräswerkzeuge 13 innerhalb der Aussparung verfahrbar sind. Ein anderer Holzblock 4.b ist mit einer weitgehend ebenen Fläche mit Hilfe nicht dargestellter Spannvorrichtungen auf der Tischebene 12 in einer wählbaren Position einspannbar.Seen from the tool slide 5 behind the Staylog bar arrangement 6, the device for milling 2 with two drivable milling tools 13 is mounted on rails, wherein it can be moved parallel to the bar construction 9. A table 11 is arranged in relation to the path of the milling device 2 in such a way that its upper table level 12 is located below the uppermost limit of the milling tools 13 in accordance with the depth of the grooves 3. A recess is made in the table plane 12 parallel and preferably symmetrically to the longitudinal axis, so that the milling tools 13 can be moved within the recess. Another wood block 4.b is with a largely flat surface can be clamped in a selectable position on the table level 12 with the aid of clamping devices (not shown).
An einer Stirnseite der Vorrichtung zum Fräsen 2 ist eine Messvorrichtung 14 so verfahrbar angeordnet, dass der Querschnitt des anderen Holzblocks 4.b bestimmt wer- den kann. Die Messvorrichtung 14 ist hierfür längs einer Schiene 15 mit Hilfe eines Antriebs quer zur Längsachse des Tisches 11 verfahrbar. Ist die Messvorrichtung 14 z.B. ein Lichtgitter, so ist an der einen Stirnseite der Vorrichtung zum Fräsen 2 ein Sender und auf der anderen Stirnseite ein Empfänger angeordnet, wobei der Sender und der Empfänger synchron verfahrbar sind. Die Vorrichtung zum Fräsen 2 und die Staylog- Balkenanordnung 6 überspannt eine Tragkonstruktion 16, an der eine Greifvorrichtung 17 horizontal verfahrbar gelagert ist. Die Greifvorrichtung 17 besteht aus zwei Armen 17.1 und 17.2, die vertikal und parallel zur Längsachse des Tisches 11 verfahrbar sind. Im Übrigen ist die Greifvorrichtung 17 im wesentlichen starr. Die gesamte Anordnung ist an eine zentrale Steuerung - z.B. eine SPS (speicherprogrammierbare Steuerung) oder einen Rechner - angeschlossen, welche die Arbeitsabläufe der Vorrichtung zum Fräsen 2, der Beschickungseinrichtung und der Staylog- Messermaschine 1 bestimmt.On one end of the milling device 2, a measuring device 14 is arranged so that the cross section of the other wooden block 4.b can be determined. For this purpose, the measuring device 14 can be moved along a rail 15 with the aid of a drive transversely to the longitudinal axis of the table 11. Is the measuring device 14 e.g. a light grid, a transmitter is arranged on one end of the milling device 2 and a receiver is arranged on the other end, the transmitter and the receiver being movable synchronously. The milling device 2 and the stay log bar arrangement 6 span a supporting structure 16 on which a gripping device 17 is mounted so that it can be moved horizontally. The gripping device 17 consists of two arms 17.1 and 17.2, which can be moved vertically and parallel to the longitudinal axis of the table 11. In addition, the gripping device 17 is essentially rigid. The entire arrangement is connected to a central controller - e.g. a PLC (programmable logic controller) or a computer - connected, which determines the work processes of the milling device 2, the loading device and the Staylog knife machine 1.
Im Betrieb ist der Holzblock 4.a auf der Balkenkonstruktion 9 eingespannt und wird in der bekannten Art gemessert.In operation, the wooden block 4.a is clamped on the beam structure 9 and is measured in the known manner.
Während des Messerns wird der andere Holzblock 4.b mit geeigneten Mitteln auf der Tischebene 12 positioniert und mit den Spannvorrichtungen eingespannt. Der Antrieb der Fräswerkzeuge 13 wird eingeschaltet und die Fräsvorrichtung 2 längs der Schienen von einer Endposition in eine andere Endposition verfahren. Hierbei erzeugen die Fräswerkzeuge 13 die beiden parallelen Nuten 3. Gleichzeitig oder anschließend wird die Messvorrichtung 14 gleichmäßig quer zur Längsachse des Tisches 1 1 verfahren und hierbei der Querschnitt des anderen Holzblocks 4.b bestimmt und zumindest vorübergehend gespeichert. Anschließend werden die Spannvorrichtungen gelöst, und die Greifvorrichtung 17 hebt den anderen Holzblock 4.b vom Tisch 11 und transportiert ihn in Richtung Staylog- Balkenanordnung 6. Hierbei wird der andere Holzblock 4.b entweder in eine Warteposition zwischen der Vorrichtung zum Fräsen 2 und der Staylog- Messermaschine 1 ge- fahren oder - wenn in der Balkenkonstuktion 9 kein Holzblock 4.a eingespannt ist - direkt auf der Auflagefläche 10 der Balkenkonstruktion 9 abgelegt, wie unten weiter beschrieben wird.During the cutting, the other wooden block 4.b is positioned on the table level 12 using suitable means and clamped with the clamping devices. The drive of the milling tools 13 is switched on and the milling device 2 is moved along the rails from one end position to another end position. Here, the milling tools 13 produce the two parallel grooves 3. Simultaneously or subsequently, the measuring device 14 is moved uniformly transversely to the longitudinal axis of the table 11 and the cross section of the other wooden block 4.b is determined and at least temporarily stored. The clamping devices are then released and the gripping device 17 lifts the other wood block 4.b from the table 11 and transports it in the direction of the stay log beam arrangement 6. Here, the other wood block 4.b is either in a waiting position between the milling device 2 and the Staylog knife machine 1 drive or - if no wooden block 4.a is clamped in the beam construction 9 - placed directly on the support surface 10 of the beam construction 9, as will be described further below.
Diese Vorgänge können mit Ausnahme des Positionierens halb- oder vollautomatisch gesteuert werden.With the exception of positioning, these processes can be controlled semi or fully automatically.
Jetzt kann ein neuer Holzblock 4.b auf dem Tisch 1 1 positioniert werden, und die beschriebenen Vorgänge beginnen erneut.Now a new block of wood 4.b can be positioned on the table 11 and the processes described begin again.
Sobald der Holzblock 4.a bis auf einen nicht weiter verwertbaren Rest zu Furnieren gemessert ist, wird der Werkzeugschlitten 5 zurück in eine Ausgangsstellung gebracht. Gleichzeitig wird die Balkenkonstruktion 9 in eine Position gedreht, in der sich die Auflagefläche 10 unten befindet, und der Holzblock 4.a wird entfernt.As soon as the wood block 4.a has been cut to veneer except for a remainder that cannot be used, the tool slide 5 is brought back into a starting position. At the same time, the beam structure 9 is rotated into a position in which the support surface 10 is at the bottom, and the wooden block 4.a is removed.
Die Balkenkonstruktion 10 wird anschließend in eine Position gedreht, in der die Auflagefläche oben ist und den anderen Holzblock 4.b aufnehmen kann. Die Greifvorrichtung 17 bringt diesen genau so auf die Auflagefläche 10, dass sich aus dieser heraus- ragende Spannklauen in den Nuten 3 befinden. Hierbei ist ein von der Greifvorrichtung 17 zurückzulegender Weg aus den Lagen der Fräsköpfe 13 und der Auflagefläche 10 bekannt und entsprechend programmiert, so dass das Ablegen des anderen Holzblocks 4.b automatisch erfolgt. Gleichzeitig wird der Werkzeugschlitten 5 in eine Arbeitsposition vorgefahren, wobei diese aus dem Querschnitt des anderen Holzblocks 4. b berechnet wird.The beam structure 10 is then rotated into a position in which the support surface is on top and can accommodate the other wooden block 4.b. The gripping device 17 brings it onto the support surface 10 in such a way that clamping claws protruding therefrom are located in the grooves 3. Here, a path to be covered by the gripping device 17 from the positions of the milling heads 13 and the contact surface 10 is known and programmed accordingly, so that the other wooden block 4.b is deposited automatically. At the same time, the tool slide 5 is moved into a working position, which is calculated from the cross section of the other wooden block 4. b.
Die Greifvorrichtung 17 wird in eine Warteposition gefahren, um dann wieder einen neuen Holzblock 4.b aufzunehmen, sobald dieser mit den Nuten 3 versehen ist.The gripping device 17 is moved into a waiting position in order to then pick up a new wood block 4.b as soon as it is provided with the grooves 3.
Die Vorgänge wiederholen sich dann. The processes are then repeated.
