Description

Der Erfindung betrifft ein Verfahren zum Bearbeiten eines plattenförmigen Werkstücks, eine Vorrichtung zum Sprühen einer Flüssigkeit und eine Verwendung einer solchen Vorrichtung zur durchlaufenden Bearbeitung eines plattenförmigen Werkstücks.The invention relates to a method for machining a plate-shaped workpiece, a device for spraying a liquid and a use of such a device for continuous machining of a plate-shaped workpiece.

Es ist bekannt, dass plattenförmige Werkstücke, wie zum Beispiel Möbelplatten aus Holz oder einem Holzwerkstoff, kantenseitig bzw. an ihrer Schmalseite mit einem sogenannten Kantenband beschichtet werden. Dies erfolgt in modernen Möbel-Fertigungsbetrieben in der Regel mittels einer mindestens eine Möbelplatte im Durchlauf bearbeitenden Maschine. Solche Maschinen werden auch als Durchlaufmaschine und/oder Kantenanleimmaschine bezeichnet. Innerhalb dieser Maschine wird die Möbelplatte beispielsweise mittels mindestens eines Förderbands (kontinuierlich) fortschreitend von einer Bearbeitungsstation zur nächsten bewegt. Somit durchläuft die Möbelplatte die Maschine.It is known that panel-shaped workpieces, such as furniture panels made of wood or a wood-based material, are coated on the edge side or on their narrow side with a so-called edge band. In modern furniture manufacturing companies, this is usually done by means of a machine that processes at least one furniture panel in a continuous process. Such machines are also referred to as throughfeed machines and / or edge banding machines. Within this machine, the furniture panel is moved progressively from one processing station to the next, for example by means of at least one conveyor belt (continuously). The furniture board thus runs through the machine.

Das Kantenband dient insbesondere auch dazu, die Optik der Möbelplatte zu verbessern und ergänzt hierbei die regelmäßig auf der oberen und/oder unteren Breitseite der Möbelplatte bereits vorhandene Dekorschicht. Darüber hinaus wird auch der hölzerne Kern der Möbelplatte durch das Kantenband und die Dekorschichten geschützt. Das Kantenband ist in der Regel aus polierbarem Kunststoff, wie z. B. Acryl oder dergleichen und kann durch eine thermische Behandlung zumindest einseitig klebfähig werden, wobei die thermische Behandlung beispielsweise mittels mindestens eines Laserstrahls oder mittels Plasmastrahlen erfolgt. Alternativ oder kumulativ kann auf das Kantenband und/oder die Schmalseite der Möbelplatte vor dem Anbringen ein Klebstoff aufgetragen werden.The edge band also serves, in particular, to improve the appearance of the furniture panel and here complements the decorative layer that is already regularly present on the upper and / or lower broad side of the furniture panel. In addition, the wooden core of the furniture board is protected by the edge tape and the decorative layers. The edge band is usually made of polishable plastic, such as. B. acrylic or the like and can be adhesive on at least one side by a thermal treatment, the thermal treatment being carried out, for example, by means of at least one laser beam or by means of plasma jets. Alternatively or Cumulatively, an adhesive can be applied to the edge band and / or the narrow side of the furniture panel before it is attached.

Beim Anbringen des Kantenbands bzw. beim Beschichten der Schmalseite der Möbelplatte mit dem Kantenband sollte jedoch verhindert werden, dass die auf der unterseitigen und/oder oberseitigen Breitseite der Möbelplatte bereits vorhandene Dekorschicht beschädigt und/oder dauerhaft verunreinigt wird. In diesem Zusammenhang ist insbesondere darauf zu achten, dass Klebstoffreste, aus der Klebefuge zwischen Kantenband und Möbelplatte heraustretendes Material (Klebstoff und/oder verflüssigter bzw. geschmolzener Kunststoff) und/oder (Fräs-)Späne nicht dauerhaft an der bzw. den Dekorschicht(en) anhaften kann bzw. können.When attaching the edge band or when coating the narrow side of the furniture panel with the edge band, however, it should be prevented that the decorative layer already present on the underside and / or the top broad side of the furniture panel is damaged and / or permanently contaminated. In this context, it is particularly important to ensure that adhesive residues, material (adhesive and / or liquefied or melted plastic) and / or (milled) chips that come out of the adhesive joint between the edge band and furniture panel do not permanently stick to the decorative layer (s) ) can adhere.

Hierzu kann ein Trennmittel und/oder ein antistatisches Mittel und/oder ein sonstiges Fluid zumindest auf Teilbereiche der unterseitigen und/oder oberseitigen Breitseite der Möbelplatte aufgebracht werden. Das Trennmittel wird hierbei zumindest in einem dem anzubringenden Kantenband zugeordneten Randbereich der Breitseite aufgetragen, um ein Anhaften von Klebstoff in diesem randseitigen Teilbereich der Breitseite zu verhindern. Hierbei konnten besonders gute Ergebnisse mit Trennmitteln erzielt werden, die relativ stark bzw. fest an der Oberfläche der Möbelplatte haften. Weiterhin können das Trennmittel und/oder das antistatische Mittel auch auf Bearbeitungswerkzeuge, wie zum Beispiel Fräsen, Abziehmesser und/oder Schwabbelscheiben, der Maschine aufgetragen werden.For this purpose, a release agent and / or an antistatic agent and / or some other fluid can be applied at least to partial areas of the broad side of the furniture board on the underside and / or on the top. The release agent is applied in this case at least in an edge area of the broad side associated with the edge band to be applied, in order to prevent adhesive from sticking in this edge-side partial area of the broad side. Particularly good results could be achieved with release agents that adhere relatively strongly or firmly to the surface of the furniture panel. Furthermore, the release agent and / or the antistatic agent can also be applied to processing tools, such as milling cutters, honing knives and / or buffing wheels, of the machine.

Zum Auftragen des Trennmittels und/oder des antistatischen Mittels und/oder sonstigen Fluids können Sprühvorrichtungen vorgesehen sein, die mit Sprühmittelbehälter zusammenwirken, in denen das Fluid gelagert wird. Der Sprühmittelbehälter kann mit einem Druckerzeuger verbunden sein, mittels dem in dem Sprühmittelbehälter ein Überdruck erzeugbar ist, sodass Fluid durch eine mit dem Sprühmittelbehälter verbundene Düse auf die Möbelplatte oder die Bearbeitungswerkzeuge gesprüht wird. Nachteilig an diesen Sprühvorrichtungen ist jedoch, dass das Fluid nicht exakt dosierbar ist, weil sich der Überdruck in dem Sprühmittelbehälter nach dem Abschalten des Druckerzeugers nur langsam abbaut. Weiterhin baut sich der Überdruck in dem Sprühmittelbehälter nach dem Abschalten des Druckerzeugers auch häufig nicht vollständig ab, sodass der Überdruck vor einem Wechsel des Sprühmittelbehälters durch vorsichtiges Öffnen eines Deckels des Sprühmittelbehälters manuell abgebaut werden muss. Außerdem können derartige Systeme aufwändig und kostenintensiv sein sowie ggf. zusätzliche Zulassungen benötigen.To apply the release agent and / or the antistatic agent and / or other fluid, spray devices can be provided which interact with spray agent containers in which the fluid is stored. The spray agent container can be connected to a pressure generator, by means of which an overpressure can be generated in the spray agent container, so that Fluid is sprayed through a nozzle connected to the spray container onto the furniture panel or the processing tools. A disadvantage of these spray devices, however, is that the fluid cannot be precisely metered because the overpressure in the spray agent container only decreases slowly after the pressure generator has been switched off. Furthermore, the overpressure in the spray agent container often does not decrease completely after the pressure generator has been switched off, so that the overpressure has to be reduced manually by carefully opening a lid of the spray agent container before changing the spray agent container. In addition, such systems can be complex and costly and may require additional approvals.

Aufgabe der Erfindung ist es daher, die geschilderten Probleme zumindest teilweise zu lösen und insbesondere ein Verfahren zum Bearbeiten eines plattenförmigen Werkstücks anzugeben, bei dem das Auftragen einer Flüssigkeit besonders exakt dosierbar ist. Zudem soll auch eine Vorrichtung zum Sprühen einer Flüssigkeit angegeben werden, mit dem die Flüssigkeit besonders exakt dosierbar ist. Weiterhin soll eine Verwendung einer entsprechenden Vorrichtung angegeben werden, durch die eine Flüssigkeit besonders exakt dosierbar ist.The object of the invention is therefore to at least partially solve the problems outlined and, in particular, to specify a method for machining a plate-shaped workpiece in which the application of a liquid can be dosed particularly precisely. In addition, a device for spraying a liquid is also to be specified, with which the liquid can be metered particularly precisely.

Hierzu dient ein Verfahren zum Bearbeiten eines plattenförmigen Werkstücks, wobei das Verfahren zumindest die folgenden Schritte aufweist:

  1. a) Bereitstellen eines Sprühmittelbehälters mit einer Flüssigkeit,
  2. b) Pumpen eines Gases in den Sprühmittelbehälter zur Erzeugung eines Überdrucks in einem Flüssigkeitsraum des Sprühmittelbehälters, sodass die Flüssigkeit aus einer mit dem Sprühmittelbehälter verbundenen Düse gesprüht wird,
  3. c) Beenden des Pumpens des Gases in den Sprühmittelbehälter, wenn das Sprühen der Flüssigkeit gestoppt werden soll,
wobei zumindest während Schritt b) oder Schritt c) zumindest ein Teil des Gases aus einer Gasöffnung des Sprühmittelbehälters aus dem Sprühmittelbehälter entweicht, sodass der Überdruck in dem Flüssigkeitsraum nach dem Beenden des Sprühens der Flüssigkeit in Schritt c) sinkt.A method for machining a plate-shaped workpiece is used for this purpose, the method having at least the following steps:
  1. a) Providing a spray agent container with a liquid,
  2. b) pumping a gas into the spray agent container to generate an overpressure in a liquid space of the spray agent container, so that the liquid is sprayed from a nozzle connected to the spray agent container,
  3. c) stop pumping the gas into the spray container if you want to stop spraying the liquid,
at least during step b) or step c) at least part of the gas escapes from a gas opening of the spray agent container from the spray agent container, so that the overpressure in the liquid space drops after the end of the spraying of the liquid in step c).

Das vorgeschlagene Verfahren dient zur durchlaufenden Bearbeitung eines plattenförmigen Werkstücks. Bei dem plattenförmigen Werkstück kann es sich beispielsweise um eine Holzplatte, Möbelplatte, Tischplatte, Arbeitsplatte oder dergleichen handeln.The proposed method is used for continuous machining of a plate-shaped workpiece. The plate-shaped workpiece can be, for example, a wooden panel, furniture panel, table top, worktop or the like.

In Schritt a) wird ein Sprühmittelbehälter mit einer Flüssigkeit im Bereich des plattenförmigen Werkstücks bzw. einer Bearbeitungsmaschine, wie zum Beispiel einer Kantenanleimmaschine, für das plattenförmige Werkstück bereitgestellt. Bei der Flüssigkeit kann es sich um ein Trennmittel und/oder ein antistatisches Mittel und/oder ein Poliermittel und/oder ein Reinigungsfluid handeln. Bei dem Sprühmittelbehälter handelt es sich insbesondere um einen (Kunststoff-)Behälter bzw. (Kunststoff-)Kanister. Der Sprühmittelbehälter weist einen Flüssigkeitsraum für die Flüssigkeit auf, der insbesondere ein Volumen von 5 Liter bis 25 Liter aufweist.In step a), a spray agent container with a liquid in the area of the plate-shaped workpiece or a processing machine, such as an edge banding machine, is provided for the plate-shaped workpiece. The liquid can be a release agent and / or an antistatic agent and / or a polishing agent and / or a cleaning fluid. The spray agent container is in particular a (plastic) container or (plastic) canister. Of the The spray container has a liquid space for the liquid, which in particular has a volume of 5 liters to 25 liters.

In Schritt b) wird ein Gas in den Sprühmittelbehälter zur Erzeugung eines Überdrucks in dem Flüssigkeitsraum gepumpt. Hierzu kann ein Druckerzeuger, beispielsweise nach Art einer (elektrischen) Pumpe, über eine Druckleitung mit dem Sprühmittelbehälter verbunden sein. Bei dem Gas handelt es sich insbesondere um Luft aus einer Umgebung des Sprühmittelbehälters. Durch den Überdruck wird die Flüssigkeit aus dem Flüssigkeitsraum über eine Flüssigkeitsleitung einer Düse zugeführt, die die Flüssigkeit (nach Art eines Sprays) versprüht. Das Versprühen der Flüssigkeit kann beispielsweise auf das plattenförmige Werkstück und/oder auf ein Bearbeitungswerkzeug für das plattenförmige Werkstück erfolgen.In step b) a gas is pumped into the spray agent container to generate an overpressure in the liquid space. For this purpose, a pressure generator, for example in the manner of an (electric) pump, can be connected to the spray agent container via a pressure line. The gas is, in particular, air from the vicinity of the spray agent container. As a result of the overpressure, the liquid is fed from the liquid space via a liquid line to a nozzle which sprays the liquid (like a spray). The liquid can be sprayed onto the plate-shaped workpiece and / or onto a machining tool for the plate-shaped workpiece, for example.

In Schritt c) wird das Pumpen des Gases in den Sprühmittelbehälter beendet, sodass das Sprühen der Flüssigkeit gestoppt wird. Hierfür kann eine Sensorik oder dergleichen vorgesehen sein, mit der erfassbar ist, wann sich ein plattenförmiges Werkstück vor der Düse befindet bzw. wann ein Spalt zwischen nacheinander zu bearbeitenden plattenförmigen Werkstücken vorliegt. Bevorzugt wird das Sprühen (immer) gestoppt, wenn sich kein plattenförmiges Werkstück vor der Düse.In step c) the pumping of the gas into the spray agent container is stopped, so that the spraying of the liquid is stopped. For this purpose, a sensor system or the like can be provided with which it is possible to detect when a plate-shaped workpiece is located in front of the nozzle or when there is a gap between plate-shaped workpieces to be processed one after the other. Spraying is preferably (always) stopped when there is no plate-shaped workpiece in front of the nozzle.

Die Verfahrensschritte a) bis c) können sich demnach sehr oft und schnell wiederholen.The process steps a) to c) can therefore be repeated very often and quickly.

Während Schritt b) und/oder Schritt c) entweicht zumindest ein Teil des Gases aus einer Gasöffnung des Sprühmittelbehälters aus dem Sprühmittelbehälter. Bei der Gasöffnung handelt es sich insbesondere um eine Öffnung in dem Sprühmittelbehälter, durch die der Flüssigkeitsraum des Sprühmittelbehälters mit einer Umgebung verbunden ist. Die Gasöffnung kann permanent geöffnet sein und/oder weist insbesondere einen Durchmesser von bis zu 10 mm [Millimetern] auf. Die Gasöffnung kann zeitweise geöffnet sein, z. B. indem ein Verschlussmittel bzw. Ventil darin betätigt (geöffnet / geschlossen) wird. Die Gasöffnung kann ggf. druckabhängig geöffnet werden, z. B. (automatisch) bei Erreichen bzw. Überschreiten eines Grenzdrucks im Sprühmittelbehälter.During step b) and / or step c) at least part of the gas escapes from a gas opening of the spray agent container from the spray agent container. The gas opening is in particular an opening in the spray agent container through which the liquid space of the spray agent container is connected to the surroundings. The gas opening can be permanently open and / or in particular has a diameter of up to 10 mm [millimeters]. The gas opening can be opened temporarily, e.g. B. by a closure means or valve is actuated (opened / closed) therein. The gas opening can be opened depending on the pressure, e.g. B. (automatically) when reaching or exceeding a limit pressure in the spray agent container.

Weiterhin ist die Gasöffnung insbesondere an einer Decke, insbesondere im Bereich eines Verschlusselements, des Flüssigkeitsraums angeordnet. Weiterhin tritt aus der Gasöffnung während des Sprühens der Flüssigkeit bevorzugt keine Flüssigkeit aus. Hierdurch sinkt der Überdruck in dem Flüssigkeitsraum unmittelbar nach dem Beenden des Sprühens der Flüssigkeit in Schritt c), sodass mit Abschalten des Druckerzeugers das Versprühen der Flüssigkeit unmittelbar beendet wird. Hierdurch kann die Flüssigkeit besonders exakt aufgetragen und dosiert werden.Furthermore, the gas opening is arranged in particular on a ceiling, in particular in the area of a closure element, of the liquid space. Furthermore, preferably no liquid emerges from the gas opening during the spraying of the liquid. As a result, the overpressure in the liquid space drops immediately after the end of the spraying of the liquid in step c), so that the spraying of the liquid is ended immediately when the pressure generator is switched off. This allows the liquid to be applied and dosed particularly precisely.

Zudem ist es vorteilhaft, wenn der Überdruck in dem Flüssigkeitsraum nach dem Beenden des Sprühens der Flüssigkeit in Schritt c) auf Atmosphärendruck sinkt. Bei dem Atmosphärendruck handelt es sich insbesondere um einen hydrostatischen Druck der Luft in der Umgebung des Sprühmittelbehälters. Der Atmosphärendruck beträgt insbesondere ca. 1 bar.In addition, it is advantageous if the overpressure in the liquid space drops to atmospheric pressure after the spraying of the liquid has ended in step c). The atmospheric pressure is, in particular, a hydrostatic pressure of the air in the vicinity of the spray agent container. The atmospheric pressure is in particular about 1 bar.

Weiterhin ist es vorteilhaft, wenn durch das Pumpen des Gases in den Sprühmittelbehälter in Schritt b) ein Überdruck in dem Flüssigkeitsraum von 0,05 bar bis 0,3 bar oberhalb eines Atmosphärendrucks erzeugt wird.
