Description
Verfahren zur Durchlauf-Bearbeitung von plattenförmigen Produkten aus Holz, Holzwerkstoffen oder artverwandten Produkten.Process for continuous processing of plate-shaped products made of wood, wood-based materials or related products.
Die Erfindung betrifft ein Verfahren zur Durchlauf-Bearbeitung von plattenförmigen Produkten aus Holz, Holzwerkstoffen oder artverwandten Produkten.The invention relates to a process for the continuous processing of plate-shaped products made of wood, wood-based materials or related products.
Die Format- und Kantenbearbeitung im kontinuierlichen Durchlauf auf verketteten Anlagen und auf hohem Automatisierungsniveau ist in der Holzbe- und -verarbeitenden Branche und artverwandten Branchen bekannt. Hier werden Platten bei hoher Mengenleistung, je nach Erfordernis und Anwendungsfall z. B. formatiert, die Schmalflächen mit verschiedensten Kantenmaterialien beschichtet und nachbearbeitet. Der Plattentransport erfolgt kontinuierlich, wobei die erreichbare Vorschubgeschwindigkeit von der Art des zu bearbeitenden Materials, der Bearbeitungsaufgabe und den Nachbearbeitungsaggregaten abhängig ist. Ferner ist auch die Bohr- und Stationärfräsbearbeitung [Einbringen von Bohrungen für z. B.Format and edge processing in a continuous cycle on linked systems and at a high level of automation is known in the woodworking and processing industry and related industries. Here plates with high volume output, depending on the requirement and application z. B. formatted, the narrow surfaces coated with various edge materials and reworked. The plate is transported continuously, whereby the achievable feed rate depends on the type of material to be processed, the processing task and the post-processing units. Furthermore, drilling and stationary milling [making holes for z. B.
Verbindungsbeschläge, Dübellochbohrungen, Türbeschläge oder auch Fräsungen für Schlösser usw.] auf sogenannten Durchlaufbohr- und Fräsautomaten im Quer- Durchlauf nach dem Durchlauftakt-Prinzip bekannt. Der Plattentransport erfolgt durch Riemenförderer im Takt. Das heißt, es wird jeweils eine Platte in die Bearbeitungsstation gefördert, der Vorschub gestoppt, die Platte ausgerichtet, gespannt, die Bearbeitung durchgeführt, entspannt und schließlich ausgefördert.Connection fittings, dowel hole bores, door fittings or also millings for locks etc.] on so-called through-hole drilling and milling machines in cross-pass according to the pass-cycle principle. The plate is transported in cycles by belt conveyors. This means that one plate is fed into the processing station, the feed is stopped, the plate is aligned, clamped, the processing is carried out, relaxed and finally discharged.
Aufgrund der Vielzahl von durchzuführenden Operationen ist die mögliche Taktleistung begrenzt. Sie liegt in der Praxis je nach Bearbeitungsaufgabe bei ca. 12 - 25 Takten/min.Due to the large number of operations to be carried out, the possible clock power is limited. In practice, depending on the processing task, it is approx. 12 - 25 cycles / min.
Mit den oben genannten Format- und Kantenbearbeitungsanlagen ist bei vielen Anwendungsfälien eine wesentlich höhere Mengenleistung möglich, weshalb die erstrebenswerte Komplettbearbeitung [Format- und Kantenbearbeitung einschließlich Bohr- und Stationärfräsbearbeitung] innerhalb einer Fertigungslinie nicht sinnvoll realisiert werden kann, da die Möglichkeiten der Format- und Kantenbearbeitungsanlagen hierdurch unzulässig eingeschränkt würden. Daher wird die Bohr- und Stationärfräsbearbeitung in der Regel außerhalb der „Linie" auf
separaten Einzelmaschinen durchgeführt.With the above-mentioned format and edge processing systems, a much higher volume output is possible in many applications, which is why the desirable complete processing [format and edge processing including drilling and stationary milling] within a production line cannot be sensibly realized, since the possibilities of the format and edge processing systems would be impermissibly restricted by this. Therefore, drilling and stationary milling are usually outside the "line" carried out separate individual machines.
Es ist daher Aufgabe der vorliegenden Erfindung, die Mengenleistung bei der Bohr- und Stationärfräsbearbeitung so zu erhöhen, daß eine Integration dieser Bearbeitungen in eine Fertigungsstraße für die Format- und Kantenbearbeitung, ohne unzulässige Einschränkung der hier möglichen Mengenleistung und unter Berücksichtigung spezifischer Branchen- und Werkstoffanforderungen möglich ist. Die spezifischen Anforderungen sind vielfältig, so sind beispielsweise bei furnierten Platten häufig die späteren „Sichtseiten" mit hochwertigerem Furnier belegt als die „Innenseiten", oder nicht sichtbare Flächen nur mit einem Gegenzugpapier, welches häufigIt is therefore an object of the present invention to increase the quantity output in drilling and stationary milling so that an integration of these operations in a production line for format and edge processing, without undue restriction of the quantity output possible here and taking into account specific industry and material requirements is possible. The specific requirements are diverse, for example in the case of veneered panels, the later "visible sides" are often covered with higher-quality veneer than the "inner sides", or invisible surfaces are only covered with a backing paper, which is often
Materialschüsselungen zur Folge hat. Die große Zahl unterschiedlicher Holzarten und Beschichtungen mit unterschiedlichen physikalischen Eigenschaften, der nicht homogene Aufbau des Holzes und die damit verbundenen Formveränderungen sind weitere Faktoren, die ihre Berücksichtigung beim Verfahren gemäß dieser Erfindung finden sollen.Material inferences. The large number of different types of wood and coatings with different physical properties, the non-homogeneous structure of the wood and the associated changes in shape are further factors which are to be taken into account in the method according to the invention.
Diese Aufgabe wird bei einem Verfahren zur Durchlauf-Bearbeitung von plattenförmigen Produkten aus Holz, Holzwerkstoffen oder artverwandten Produkten durch folgende Verfahrensschritte gelöst: a. die zugeführten Platten werden so in einem Magazin zwischengepuffert, daß die zu bearbeitenden Flächen im Wechsel unten/oben liegen, b. zwei übereinanderliegende Platten werden gemeinsam so einer Bohr- und/oder Frässtation zugeführt, daß die zu bearbeitenden Flächen außen liegen, c. die übereinanderliegenden Platten werden in einem Takt gemeinsam und gleichzeitig an ihren außenliegenden Flächen und/oder ihren Schmalseiten bearbeitet, und d. die einseitig bearbeiteten Platten werden vereinzelt.This task is solved in a process for the continuous processing of plate-shaped products made of wood, wood-based materials or related products by the following process steps: a. the fed plates are buffered in a magazine in such a way that the surfaces to be processed are alternately below / above, b. two superimposed plates are jointly fed to a drilling and / or milling station in such a way that the surfaces to be machined are on the outside, c. the superimposed plates are processed together in one cycle and simultaneously on their outer surfaces and / or their narrow sides, and d. the plates processed on one side are separated.
Infolge dieser Ausgestaltung können immer zwei Platten gleichzeitig bearbeitet werden, wodurch eine höhere Mengenleistung erzielt werden kann. Dies erlaubt eine sinnvolle Integration der Bohr- und Stationärfräsbearbeitung in die bekannten, kontinuierlich arbeitenden Fertigungsstraßen für die Format- und Kantenbearbeitung. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.
Sofern aus konstruktiven Gründen, z. B. wegen Platzmangels in einer ersten, die Verfahrensschritte nach Patentanspruch 1 ausführenden Bearbeitungsvorrichtung, eine erneute Bearbeitung der bereits bearbeiteten Flächen erforderlich ist, können in vorteilhafter Weiterbildung der Erfindung die folgenden Schritte durchgeführt werden: a. nach dem Vereinzeln der Platten werden die Platten erneut so in einem Magazin zwischengepuffert, daß die bereits bearbeiteten Flächen jeweils unten/oben liegen, b. zwei übereinanderliegende Platten werden gemeinsam so einer Bohr- und/oder Frässtation zugeführt, daß die zu bearbeitenden Flächen außen liegen, c. die übereinanderliegenden Platten werden in einer zweiten Bohr- und/oder Frässtation in einem Takt gemeinsam und gleichzeitig an ihren außenliegendenAs a result of this configuration, two plates can always be processed simultaneously, as a result of which a higher volume output can be achieved. This allows a meaningful integration of drilling and stationary milling in the well-known, continuously working production lines for format and edge processing. Advantageous further developments result from the subclaims. If for structural reasons, e.g. B. due to lack of space in a first, the method steps according to claim 1 executing processing device, a new processing of the previously processed surfaces is required, the following steps can be carried out in an advantageous development of the invention: a. after the plates have been separated, the plates are buffered again in a magazine so that the surfaces that have already been processed are located below / above, b. two superimposed plates are jointly fed to a drilling and / or milling station in such a way that the surfaces to be machined are on the outside, c. the superimposed plates are combined in a second drilling and / or milling station in one cycle and simultaneously on their external ones
Flächen und/oder ihren Schmalflächen bearbeitet, um weitere Bohr- und/oder Fräsvorgänge durchzuführen, und d. die bearbeiteten Platten werden vereinzelt.Machined surfaces and / or their narrow surfaces to perform further drilling and / or milling operations, and d. the processed plates are separated.
Wenn die plattenförmigen Werkstücke auf beiden Seiten bearbeitet werden sollen, sind vorteilhafterweise die folgenden Verfahrensschritte vorgesehen: a. im Falle einer beidseitigen Flächenbearbeitung werden die Platten erneut so in einem Magazin zwischengepuffert, daß die zuvor bearbeiteten Flächen jeweils im Wechsel oben/unten liegen, b. zwei übereinanderliegende Platten werden so einer Bohr- und/oder Frässtation zugeführt, daß die bisher nicht bearbeiteten Flächen außen liegen, c. die übereinanderliegenden Platten werden in einem Takt gemeinsam und gleichzeitig an ihren bisher nicht bearbeiteten Flächen und/oder ihren Schmalseiten bearbeitet, und d. die beidseits bearbeiteten Platten werden vereinzelt.If the plate-shaped workpieces are to be processed on both sides, the following method steps are advantageously provided: a. in the case of double-sided surface processing, the plates are again buffered in a magazine so that the previously processed surfaces are alternately up / down, b. two plates lying one above the other are fed to a drilling and / or milling station in such a way that the previously unworked surfaces are on the outside, c. the superimposed plates are processed together in one cycle and simultaneously on their previously unprocessed surfaces and / or their narrow sides, and d. the plates processed on both sides are separated.
Damit nach einer vollständigen Bearbeitung alle Werkstücke gleich ausgerichtet sind, ist nach einer besonderen Weiterbildung vorgesehen, daß am Ende der vollständigen Bearbeitung der Platten jede zweite Platte so gewendet wird, daß ihre zuletzt bearbeitete Fläche unten liegt.So that after a complete machining all workpieces are aligned, a special development provides that at the end of the complete machining of the plates every second plate is turned so that its last machined surface is at the bottom.
Gemäß einer vorteilhaften Weiterbildung ist weiterhin vorgesehen, daß die Platten gereinigt werden, bevor sie im Magazin zwischengepuffert werden. Durch diese
Maßnahme wird ein sicherer Transport der übereinanderliegenden Platten gewährleistet und Ungenauigkeiten bei der Bearbeitung aufgrund von Verschmutzungen vermieden.According to an advantageous development, it is further provided that the plates are cleaned before they are buffered in the magazine. Through this This ensures a safe transport of the overlapping panels and avoids inaccuracies during processing due to contamination.
Unter Bezugnahme auf die Figuren wird im folgenden die Erfindung näher erläutert.The invention is explained in more detail below with reference to the figures.
Hierbei wird zunächst auf FIG. 1 mit den Bezugsziffern 1 - 9 Bezug genommen. Die entsprechenden Vorrichtungen werden, soweit dies zum Verständnis des Verfahrens erforderlich erscheint beschrieben, sind aber nicht dargestellt.First, FIG. 1 with the reference numbers 1-9. The corresponding devices are described insofar as this appears necessary for understanding the method, but are not shown.
Die zugeführten Platten (1 ) werden durch eine handelsübliche Reinigungsmaschine gesäubert (je nach Erfordernis Ober- und/oder Unterseite), um negative Einflüsse (z. B. Flächenbeschädigungen oder Bearbeitungsungenauigkeiten) bei den nachfolgenden Verfahrensschritten sicher auszuschließen.The supplied plates (1) are cleaned using a commercially available cleaning machine (top and / or bottom, depending on requirements) in order to reliably rule out negative influences (e.g. surface damage or processing inaccuracies) in the subsequent process steps.
Anschließend werden die Platten auf ein Riemenfördersystem mit aufgebauter Portalbrücke übergeben, an der pendelnd gelagerte, mit Dämpfungsmaterial beschichtete Haken befestigt sind, die ein sicheres und beschädigungsfreies Wenden auch sehr empfindlicher und weicher Materialien ermöglichen (im folgenden als „Pendelwender" bezeichnet).The plates are then transferred to a belt conveyor system with a built-in portal bridge, on which pendulum-mounted hooks coated with damping material are attached, which enable safe and damage-free turning of even very sensitive and soft materials (hereinafter referred to as "pendulum turner").
Das System läßt die Funktionen - jede Platte wendenThe system lets the functions - every plate turn
- nicht wenden- do not turn
- jede zweite Platte wenden (2)- turn every other plate (2)
- jede erste Platte wenden zu, so daß die gewünschte Lage der Bearbeitungsflächen (3) im nachgeschalteten Magazin in Abhängigkeit von den Vorbedingungen erreicht wird.- Turn each first plate so that the desired position of the processing surfaces (3) in the downstream magazine is achieved depending on the preconditions.
Die Übergabe in das Magazin erfolgt mit hoher Geschwindigkeit und ist gegen vorzeitiges Abkippen gesichert, so daß eine flache „Flugbahn" entsteht. Zusammen mit der begrenzten, auf die Materialeigenschaften abgestimmte Fallhöhe und den eingebauten Endlagendämpfern zur Aufnahme der kinetischen Energie erfolgt eine beschädigungsfreie Stapelbildung in der gewünschten
Form (3). Im nächsten Verfahrensschritt (4) werden dem Magazin mit Hilfe eines kombinierten Riemen-/Nockenkettensystems zwei Platten gleichzeitig entnommen und der ersten Bohrstation zugeführt. Das Transportsystem besteht aus zwei synchronisierten/kombinierten Riemen-/Nockensystemen (links/rechts), welche in den Bohrautomaten integriert sind. Die Werkstücke (untere Platte) liegen auf dem gegenüber dem Nockensystem geringfügig langsamer laufendem Riemen auf, so daß einerseits für einen formschlüssigen und damit verkantungsfreien, andererseits für einen von „Schleifspuren" freien Transport gesorgt ist. Das System arbeitet im Takt, fördert die beiden übereinanderliegenden Platten zunächst in die Bearbeitungsstation, die Bearbeitung wird ausgeführt, die Platten werden ausgefördert und auf ein in Durchlaufrichtung überlappend angeordnetes, mit dem Riemen-/Nockensystem synchronisiertes, kontinuierlich laufendes Riemenfördersystem weitgehend „kräftefrei" übergeben. Das System gewährleistet den beschädigungsfreien und sicheren Transport im „Doppelpack" auch bei relativ glatten Oberflächen und nicht ebenen Flächen, wie sie im beschriebenen Anwendungsgebiet vorkommen. Von hier werden die Platten gemeinsam einem Fördersystem mit integrierter Vereinzelungsvorrichtung zugeführt, vereinzelt (5) und anschließend mit Hilfe einer handelsüblichen Abblasmaschine rundum gereinigt.The transfer into the magazine takes place at high speed and is secured against premature tipping, so that a flat "trajectory" is created. Together with the limited drop height, which is matched to the material properties, and the built-in end position dampers for absorbing the kinetic energy, a damage-free stack formation occurs in the desired Form (3). In the next process step (4), two plates are removed from the magazine simultaneously using a combined belt / cam chain system and fed to the first drilling station. The transport system consists of two synchronized / combined belt / cam systems (left / right), which are integrated in the automatic drilling machines. The workpieces (lower plate) rest on the belt, which runs slightly slower than the cam system, so that, on the one hand, there is a form-fitting and therefore tilt-free, and on the other hand a "grinding marks" free transport is provided Plates first into the processing station, the processing is carried out, the plates are conveyed out and transferred to a continuously running belt conveyor system that is overlapping in the direction of flow and is synchronized with the belt / cam system and is largely "force-free". The system ensures damage-free and safe transport in a "double pack" even with relatively smooth surfaces and non-flat surfaces, such as those found in the application area described. From here, the plates are fed together to a conveyor system with an integrated separating device, separated (5) and then with the help completely cleaned on a conventional blow-off machine.
Im nächsten Arbeitsgang (6) erfolgt eine erneute Stapelbildung gemäßIn the next step (6), a new stack formation takes place in accordance with
Arbeitsgang (3), dann die Komplettierung der Bearbeitung (8) wie in Arbeitsgang (4) beschrieben.Operation (3), then completing the processing (8) as described in operation (4).
In Abhängigkeit von den Anforderungen werden die Platten gegebenenfalls gewendet (9), wobei die gleichen Funktionsoptionen wie bei Arbeitsgang (2) zur Verfügung stehen.Depending on the requirements, the plates may be turned over (9), whereby the same functional options as for operation (2) are available.
Die in FIG. 1 gezeigten und in den Verfahrensschritten (4) und (7) durchzuführenden Bearbeitungen sind beliebig gewählt und dienen nur der Veranschaulichung.The in FIG. 1 and to be carried out in process steps (4) and (7) are arbitrary and are used only for illustration.
Die Aggregatbestückung der Bearbeitungsstationen und damit die möglichen Bearbeitungen sind jeweils auf den Anwendungsfall abzustimmen. Im übrigen läßt sich das Verfahren flexibel auf den jeweiligen Anwendungsfall bezogen gestalten.
Sämtliche Transportsysteme sollten mindestens mit manuell regelbaren Vorschubantrieben ausgerüstet sein, um einen auf die jeweiligen Produkte abgestimmten Ablauf sicherzustellen.The assembly equipment of the processing stations and thus the possible processing must be matched to the application. Otherwise, the method can be designed flexibly in relation to the respective application. All transport systems should at least be equipped with manually controllable feed drives to ensure that the process is tailored to the respective products.
Mit der Erfindung werden insbesondere folgende Vorteile erzielt: Verdoppelung der Mengenleistung gegenüber der konventionellen Verfahrensweise, welches eine Integration der Bohr- und Stationärfräsbearbeitung in Linie mit einer kontinuierlich im Durchlauf arbeitenden Format- und Kantenbearbeitungsanlage sinnvoll möglich macht.In particular, the following advantages are achieved with the invention: Doubling of the quantity output compared to the conventional procedure, which makes it possible to integrate drilling and stationary milling in line with a continuously working format and edge processing system.

Here the panels are formatted, glued to the narrow surfaces of veneer edges, completely reworked and, depending on the product, further processing if necessary carried out. Then the cone turning station (3) is used to turn from "longitudinal" to "transverse" and transfer it to the format and edge processing system (4). This is where the cross-processing takes place (processing as in Appendix 2, depending on the product).
