Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Einstreichen einer flüssigen oder pastösen Ausgleichsmasse in die offenen, porenartigen Hohlräume an den angeschnittenen Kantenflächen von Werkstücken aus Spanmaterial gemäß den Gattungsmerkmalen des Patentanspruchs 1.The invention relates to a device for painting a liquid or pasty leveling compound in the open, pore-like cavities on the cut Edge surfaces of workpieces made of chip material according to the Generic features of claim 1.

Spanplatten werden aus einer Schüttung, die im Windsichtverfahren gebildet wird, gepreßt, wobei die feinen Holzpartikel sich beidseits an den Außenflächen der Spanplatte finden, während zur Mitte der Spanplatte hin die groberen Späne angeordnet sind. Bei der Fertigung von Möbel- oder Innenausbauteilen aus einem solchen Spanplattenmaterial muß auch an den Schmalflächenseiten eine Oberflächenbeschichtung aufgebracht werden, durch die hindurch die grobere Struktur des Spanplattenmaterials zur Mitte hin nicht sichtbar sein soll. Besondere Schwierigkeiten ergeben sich hierbei dann, wenn das betreffende Werkstück an seinen Schmalflächenseiten mit einer besonderen Kontur versehen ist, wie einer Kantenrundung oder -profilierung, die entlang der Werkstückkanten angefräst wird. Hierbei ergeben sich in der Regel angeschnittene Kantenflächen an den Werkstücken, in deren Bereich ein mehr oder weniger breiter Streifen sich erstreckt, an dem das grobere, gebundene Spanmaterial freiliegt. Hier bestehen zwischen den einzelnen Spanpartikeln offene, porenartige Hohlräume, die den angeschnittenen Kantenflächen ein zerklüftetes Aussehen geben. Particle boards are made from a bed made using the air classifier method is formed, pressed, the fine wood particles on both sides of the outer surfaces of the chipboard find the larger ones towards the center of the chipboard Chips are arranged. In the manufacture of furniture or Interior components made of such a chipboard material must a surface coating also on the narrow surface sides are applied, through which the coarser Structure of the chipboard material not towards the middle should be visible. Particular difficulties arise in this case when the workpiece in question has its Provide narrow sides with a special contour is like an edge rounding or profiling that goes along the workpiece edges are milled. Here result usually cut edge surfaces on the workpieces, in their area a more or less broad Streak extends to where the coarser, bound Chip material is exposed. Here exist between the individual Chip particles open, pore-like cavities that the cut edges give a rugged appearance.

Es gibt verschiedene Verfahren und Vorrichtungen, um in solche angeschnittenen Kantenflächen von Werkstücken aus Spanplattenmaterial eine Ausgleichs- oder Vergütungsmasse einzustreichen, mit der die offenen Poren an den Kantenflächen der Werkstücke geschlossen werden, damit sich hier eine glatte Oberfläche bildet, auf die ein Beschichtungsmaterial, wie eine Folie, ein Furnier oder ein Lack, so aufgetragen werden kann, daß im nachhinein an der Sichtseite die grobe Spanstruktur nicht mehr zu erkennen ist. Unmittelbar beim Aufbringen haben die Ausgleichsmassen eine flüssige oder pastöse Konsistenz und sie härten nach dem Auftragen aus. In bekannter Weise wird das Einstreichen mittels eines Rakels, einer Rolle oder eines Spatels vorgenommen, an dem die Werkstücke im Durchlauf vorbeigeführt werden. Da sich an der Anlaufseite des Rakels ein Stau der Ausgleichsmasse bildet, ist ein kontrollierter Auftrag der Ausgleichsmasse nicht zu erzielen, entsprechend zeigt die Oberfläche der ausgehärteten Ausgleichsmasse Unregelmäßigkeiten, die in einer aufwendigen Nachbearbeitung beispielsweise durch Schleifen beseitigt werden müssen. Es ist deshalb auch schon vorgesehen worden, die auf die Werkstück-Kantenflächen aufzutragende Ausgleichsmasse auf ein umlaufendes Band aufzubringen, an dem die Werkstücke mit ihren zu beschichtenden Kantenflächen vorbeigeführt werden.There are various methods and devices to get in such cut edge surfaces from workpieces Chipboard material is a leveling or remuneration compound with which the open pores on the edge surfaces of the workpieces are closed so that there is a forms a smooth surface on which a coating material like a foil, a veneer or a varnish, so applied can be that in retrospect the coarse chip structure is no longer recognizable. Right away when applying the leveling compounds have a liquid or pasty consistency and they harden after application out. In a known manner, the painting is carried out by means of a Squeegee, a roller or a spatula on which the workpieces are passed in one pass. That I a jam of the balancing mass on the starting side of the squeegee forms, is a controlled application of the balancing mass cannot be achieved, the surface of the cured leveling irregularities in complex post-processing, for example Loops must be eliminated. That's why it is has already been provided on the workpiece edge surfaces leveling compound to be applied to a rotating one Apply tape on which the workpieces with their be guided past the edge surfaces to be coated.

Ergänzend hierzu beschreibt das Dokument US 5 085 891 A eine Versiegelungsvorrichtung zur Nachbehandlung von Kanten an Werkstücken, die aus einer Materialkomposition bestehen. Die bekannte Vorrichtung weist einen Körper nach Art eines Gleitsteins mit einer Nut auf, die an die Kantenkontur des jeweiligen Werkstücks angepaßt ist. Im Bereich dieser Nut findet sich eine Einlaßdüse, durch die hindurch ein Kanten-Versiegelungsmaterial, wie ein geschmolzener thermoplastischer Kunststoff, eingedrückt wird. Aufgrund einer erzeugten Relativbewegung zwischen dem Werkstück und der genannten Vorrichtung wird entlang der gesamten Werkstückkante eine Beschichtung aufgebracht. Eine ähnliche Vorrichtung beschreibt ebenfalls das Dokument AU 549 776 B, auch hier wird ein Versiegelungsmaterial auf das Kantenprofil einer Platte aufgebracht, die aus einem Partikelwerkstoff besteht.In addition to this, the document US 5 085 891 A describes a Sealing device for post-treatment of edges on workpieces that consist of a material composition. The known device has a body like a Sliding block with a groove on the edge contour of the is adapted to the respective workpiece. In the area of this groove there is an inlet nozzle through which an edge sealing material like a melted thermoplastic Plastic that is pushed in. Due to a generated Relative movement between the workpiece and the above Device is along the entire edge of the workpiece applied a coating. A similar device also describes document AU 549 776 B, also here is a sealing material on the edge profile of a Plate applied, which consists of a particle material.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mit der ein exakteres Einstreichen der Ausgleichsmasse unter tieferem Eindringen in die angeschnittenen Kantenflächen der Werkstücke infolge eines hohen Preßdrucks in der länglichen Hohle oder Nut des Gleitsteins möglich ist. Diese Aufgabe wird nach der Erfindung bei einer solchen Vorrichtung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.The invention is based on the object of a device of the type mentioned at the beginning, with the one more precise application of the leveling compound under deeper Penetration into the cut edge surfaces of the workpieces due to a high pressure in the elongated Hollow or groove of the sliding block is possible. This object is achieved according to the invention in such Device by the characterizing features of the claim 1 solved.

Für die Erfindung ist wesentlich, daß die zu behandelnden Werkstück-Kantenflächen über eine längere Strecke hinweg in Kontakt mit der Ausgleichsmasse gebracht werden, wobei durch entsprechende Querschnitts- und Oberflächengestaltung der länglichen Hohle oder Nut im Gleitstein Einfluß auf eine glatte Ausbildung der Oberfläche der ausgehärteten Ausgleichsmasse genommen werden kann.It is essential for the invention that the to be treated Workpiece edge surfaces over a longer distance in Be brought into contact with the balancing mass, whereby through appropriate cross-sectional and surface design the elongated hollow or groove in the sliding block influences one smooth formation of the surface of the hardened leveling compound can be taken.

Die Erfindung wird nachfolgend anhand der Zeichnung an einem Ausführungsbeispiel noch näher erläutert. Dabei zeigen:

Im einzelnen zeigt Figur 1 ein Werkstück 1, bei dem es sich um eine Leiste handelt, die aus einem Spanplattenmaterial geschnitten worden ist. Wie insbesondere Figur 3 veranschaulicht, hat das Werkstück 1 eine durch Fräsen hergestellte, gerundete Kantenfläche 2, an der entsprechend dem Spanplatten-Ausgangsmaterial besonders im mittleren Bereich zwischen groberen Spanpartikeln offene Poren bestehen, die für eine nachfolgende Beschichtung geschlossen werden müssen. Hierzu wird auf die Kantenfläche 2 des Werkstücks 1 eine Ausgleichsmasse aufgetragen und in die Poren eingestrichen, was im Durchlauf geschieht. Dazu wird das Werkstück 1 gegen eine Fördervorrichtung 3 gedrückt, die aus einer Mehr- oder Vielzahl von Vorschubrollen 4 besteht, die sich zu einer geradlinigen Förderstrecke ergänzen.1 shows a workpiece 1 in which it is is a strip made of a chipboard material has been cut. As particularly illustrated in FIG. 3, the workpiece 1 has a milling rounded edge surface 2, on the corresponding to the Chipboard base material, especially in the middle area There are open pores between coarse chip particles that must be closed for a subsequent coating. For this purpose, the edge surface 2 of the workpiece 1 applied a leveling compound and brushed it into the pores, what happens in the run. To do this, the workpiece 1 pressed against a conveyor 3, the a plurality or a plurality of feed rollers 4, which complement each other to form a straight conveyor line.

Gegenüber der Fördervorrichtung 3 ist ein Gleitstein 5 angeordnet, zwischen dem und der Fördervorrichtung 3 das Werkstück 1 hindurchgeführt wird, wobei der Gleitstein auch das Andrücken des Werkstücks 1 an die Fördervorrichtung 3 besorgen kann.A sliding block 5 is arranged opposite the conveying device 3, between that and the conveyor 3 that Workpiece 1 is passed, the sliding block also pressing the workpiece 1 onto the conveyor device 3 can get.

Der Gleitstein hat entlang seiner dem Werkstück 1 zugekehrten Längsseite eine Hohle oder Nut 6, deren Querschnittsgrundform Figur 3 zu entnehmen ist. Das Werkstück 1 taucht mit seiner zu behandelnden Kantenfläche 2 in diese Nut 6 ein, weshalb eine Anpassung der Querschnittsgestalt der Nut 6 an die jeweilige Querschnittsform der Werkstück-Kantenfläche 2 erforderlich ist. Je nach Ausbildung der Werkstück-Kantenfläche 2 muß ein entsprechend angepaßter Gleitstein 5 verwendet werden.The sliding block has facing the workpiece 1 Long side a cavity or groove 6, the basic cross-sectional shape Figure 3 can be seen. The workpiece 1 dips with its edge surface 2 to be treated in this groove 6 a, which is why an adjustment of the cross-sectional shape of the groove 6 to the respective cross-sectional shape of the workpiece edge surface 2 is required. Depending on the design of the workpiece edge surface 2 must have an appropriately adapted sliding block 5 can be used.

In die Nut 6 des Gleitsteins 5 wird die Ausgleichsmasse eingedrückt, dies geschieht über einen Kanal 7, von dem aus zwei kanalförmige Einlässe 8 abgezweigt sind, wie sich aus den Figuren 2 und 3 ergibt. An der Mündungsstelle der Einlässe 8 hat die Nut 6 ihren größten Querschnitt, hier ist ein vergrößerter Nutraum 9 gebildet, um an dieser Stelle eine größere Menge der Ausgleichsmasse zur Verfügung zu haben. Von diesem vergrößerten Nutraum 9 aus nimmt das in Richtung des Pfeils A durchlaufende Werkstück 1 an seiner Kantenfläche 2 die Ausgleichsmasse mit, die bis zum Auslaufende am Nutstein 5 mehr und mehr verpreßt wird, weil sich zum Auslaufende hin der Querschnitt der Nut 6 verjüngt. Man erkennt hierzu in Figur 1 einen relativ zur Werkstück-Kantenfläche 2 zum Auslaufende hin ansteigende Nutgrund 10, durch den ein sich zum Auslaufende hin verjüngender Mitnahmespalt 11 für die Ausgleichsmasse gebildet ist. Damit sich die Ausgleichsmasse nicht aus dem Mitnahmespalt 11 herausgedrückt, ist für eine Abdichtung gesorgt, wie Figur 3 veranschaulicht. Die zu beschichtende Kantenfläche 2 des Werkstücks 1 ist durch parallele Längskanten 12 begrenzt, die dicht an den Flanken 13 der Nut 6 anliegen und daran entlanggleiten. Hierdurch wird verhindert, daß die Ausgleichsmasse auf die Seitenflächen des Werkstücks 1 übertritt, wo sie deren Oberflächengüte beeinträchtigen würde.The balancing mass is in the groove 6 of the sliding block 5 indented, this happens via a channel 7 from which two channel-shaped inlets 8 are branched out as is Figures 2 and 3 results. At the mouth of the inlets 8, the groove 6 has its largest cross section, here is an enlarged groove space 9 is formed to at this point to have a larger amount of the balancing mass available. From this enlarged groove space 9 takes in Direction of arrow A passing workpiece 1 on it Edge surface 2 with the leveling compound that to the end of the outlet on the sliding block 5 is pressed more and more because the cross section of the groove 6 tapers towards the outlet end. One can see this in Figure 1 relative to Workpiece edge surface 2 rising towards the end of the runout Groove bottom 10, through which a tapering towards the outlet end Driving gap 11 formed for the balancing mass is. So that the leveling compound does not come out of the driving gap 11 pushed out, provides a seal, as Figure 3 illustrates. The edge surface to be coated 2 of the workpiece 1 is by parallel longitudinal edges 12 limited, which lie close to the flanks 13 of the groove 6 and slide along it. This prevents the leveling compound on the side surfaces of the workpiece 1 passes where they affect their surface quality would.

In Figur 1 ist das Spaltmaß S am Auslaufende der Nut 6 des Gleitsteins 5 und das Spaltmaß S' an der Einlaufseite angegeben, wobei letzteres um einiges größer als das Spaltmaß S am Auslaufende des Mitnahmespaltes 11 ist. Aufgrund der Wählbarkeit dieses Spaltmaßes S kann man die Schichtdicke bestimmen, mit der die Ausgleichsmasse auf die Werkstück-Kantenfläche 2 aufgetragen werden soll. In Figure 1, the gap dimension S at the outlet end of the groove 6 of the Sliding block 5 and the gap dimension S 'indicated on the inlet side, the latter being somewhat larger than the gap dimension S at the outlet end of the driving gap 11. Due to the Selectability of this gap dimension S can be the layer thickness determine with which the compensating mass on the workpiece edge surface 2 should be applied.

Der Gleitstein 5 wird gegen das jeweilige Werkstück 1 tastend angedrückt, was bedeutet, daß er etwaigen Toleranzen der Werkstückkante nachfolgt und keine Zwänge zwischen dem Gleitstein 5 und dem jeweiligen Werkstück 1 bestehen können. Damit ein Anecken an der Einlaufseite des Gleitsteins 5 unterbunden ist, erweitert sich hier die Nut 6, um eine Einlaufschräge 14 zu bilden.The sliding block 5 is groping against the respective workpiece 1 pressed, which means that he has any tolerances follows the workpiece edge and no constraints between the Sliding block 5 and the respective workpiece 1 can exist. So that a bump on the inlet side of the sliding block 5 is prevented, the groove 6 expands here by one Form slope 14.

In der Regel wird eine Ausgleichsmasse verwendet, die durch Wärme verflüssigbar, also schmelzbar ist. Damit sich keine allzu schnelle Erkaltung und Erstarrung der Ausgleichsmasse, die über den Mitnahmespalt 11 in der Nut 6 mitgezogen wird, einstellt, ist im Gleitstein 5 ein Heizstab 15 angeordnet, der im wesentlichen parallel zur Nut 6 liegt.As a rule, a leveling compound is used, which by Heat can be liquefied, i.e. it can be melted. So that none too rapid cooling and solidification of the balancing mass, pulled along in the slot 6 in the groove 6 is, a heating rod 15 is in the sliding block 5 arranged, which is substantially parallel to the groove 6.

Der Gleitstein 5 ist an einem Support 16 angeordnet, der in Richtung zur Fördervorrichtung 3 hin zustellbar ist, wobei der Support 16 in insgesamt drei Achsen verstellbar ist. Die elastische Anlage des Gleitsteins 5 an der Kantenfläche 2 des Werkstücks 1 ist durch eine Druckfedervorrichtung 17, 18 bewirkt, die aus einem Pneumatikzylinder und aus auftrennbaren Schubstangen 17 besteht, damit der Gleitstein 5 am Support 16 ausgewechselt werden kann. Der Federweg des Gleitsteins 5 gegenüber dem Support 6 wird zum einen durch Schraubbolzen 19 begrenzt, welche diese beiden Teile miteinander verbinden, wobei der Gleitsein 5 auf dem Schaft der Schraubbolzen 19 axial verschieblich ist. Die Endlage des Gleitseins 5 wird durch einen Anschlag bildende Muttern 20 vorgegeben, die zur Justage des Gleitsteins 5 verstellt werden können. Der Federweg des Gleitsteins 5 zum Support 16 hin wird durch Anschlagbolzen 21 begrenzt, die am Support 16 sitzen und in Richtung zum Gleitstein 5 hin vorstehen. Die pneumatische Anfederung des Gleitsteins 5 gleicht die bei einem Spanmaterial nicht zu vermeidenden Toleranzen aus, damit die Werkstückkanten 12 stets in Kontakt mit den Nutflanken 13 bleiben, vgl. Figur 3.The sliding block 5 is arranged on a support 16, which in Direction to the conveyor 3 is deliverable, wherein the support 16 is adjustable in a total of three axes. The elastic contact of the sliding block 5 on the edge surface 2 of the workpiece 1 is by a compression spring device 17, 18 causes that from a pneumatic cylinder and from separable Push rods 17 so that the sliding block 5th can be replaced at Support 16. The travel of the The sliding block 5 opposite the support 6 is on the one hand Bolt 19 limits which these two parts together connect with the sliding 5 on the shaft the bolt 19 is axially displaceable. The end position the sliding 5 is by a stop forming nuts 20 specified, which is adjusted to adjust the sliding block 5 can be. The travel of the sliding block 5 to support 16 out is limited by stop bolts 21, which are on the support 16 sit and protrude towards the sliding block 5. The pneumatic suspension of the sliding block 5 is the same the tolerances that cannot be avoided with a chip material so that the workpiece edges 12 are always in contact with the Groove edges 13 remain, cf. Figure 3.

Eine entsprechende Durchlaufmaschine oder -vorrichtung kann hintereinander mehrere solche Trägersysteme aufweisen, wie es im Prinzip in Figur 1 dargestellt ist. Man kann damit zum einen die Schichtdicke der aufgetragenen Ausgleichsmasse beeinflussen, zum anderen aber auch kompliziertere Profilierungen an den Werkstück-Kantenflächen 2 partiell beschichten, indem man beispielsweise mit einem Gleitstein 5 einen konvex gerundeten Bereich und mit einem anderen Gleitstein 5 einen konkav gerundeten Bereich der Werkstückkantenfläche 2 beschichtet.A corresponding continuous machine or device can have several such carrier systems in succession, such as it is shown in principle in Figure 1. You can use it on the one hand, the layer thickness of the applied leveling compound influence, but also more complicated Profiling on the workpiece edge surfaces 2 partially coat, for example with a sliding block 5 a convex rounded area and with another Sliding block 5 a concavely rounded area of the workpiece edge surface 2 coated.
