Description

Vorrichtung zum ein- oder mehrseitigen Umleimen von Holzteilen mit Vollholz-oder stärkeren Furnierkanten Es ist in der holzverarbeitenden Industrie bekannt, Vollholz- oder Furnierkanten an Holzteilen, z. B. an Tischplatten, beliebiger Form anzuleimen, d. h. die Holzteile mit den Kanten zu umleimen. Die bisher üblichen Arbeitsmethoden sind jedoch sehr umständlich und zeitraubend und verhindern in vielen Fällen einen glatten Arbeitsverlauf innerhalb eines festgelegten Fertigungsprogramms.Device for one-sided or multiple-sided gluing of wooden parts with Solid wood or thicker veneer edges It is used in the woodworking industry known, solid wood or veneer edges on wooden parts, z. B. on table tops, any To glue the form, d. H. to glue the wooden parts with the edges. The usual ones so far However, working methods are very cumbersome and time consuming and prevent in many Cases a smooth work process within a defined production program.

Bei den bekannten Spanntischen zur Kantenumleimung kann es vorkommen, daß bei zu großem seitlichem Preßdruck das zu umleimende Teil aus der Presse herausspringt, was nicht selten eine Verletzung der Bedienungsperson zur Folge hat. With the known clamping tables for edge banding, it can happen that if the side pressure is too great, the part to be glued jumps out of the press, which often results in injury to the operator.

Den bekannten Vorrichtungen gegenüber zeichnet sich der Gegenstand der Erfindung dadurch aus, daß bei ihm gerade oder gebogene Leisten unter Druck passend zugeschnitten werden können. Die Druck elektrode drückt dabei die Platte undl die zu verleimenden Kanten bündig, so daß nicht wie bisher ein Niederklopfen von Hand erforderlich ist. Ferner kann das zu umleimende Gut bei zugefahrener Presse nicht herausspringen, so daß die Unfall gefahr weitgehend vermindert wird. Diese und weitere Vorteile werden erfindungsgemäß dadurch erzielt, daß über den Rand des Gutes hinausragende Teile der Elektrodenplatten einen Führungsspalt der Druckzulagen bilden, dessen lichte Weite größer ist als die Dicke der Druckzulagen. The subject stands out from the known devices of the invention in that it is straight or curved strips under pressure can be cut to fit. The pressure electrode presses the plate undl the edges to be glued flush so that there is no knocking down as before by hand is required. Furthermore, the material to be glued can be removed when the press is closed do not jump out, so that the risk of an accident is largely reduced. These and further advantages are achieved according to the invention in that over the edge of the Good protruding parts of the electrode plates create a guide gap for the pressure supports form, the clear width is greater than the thickness of the pressure supplements.

An Hand der Zeichnung werden ein Ausführungsbeispiel und weitere Einzelheiten der Erfindung näher erläutert. An exemplary embodiment and others are illustrated with the aid of the drawing Details of the invention explained in more detail.

Fig. 1 stellt einen Schnitt gemäß der Linie A-B der in Fig. 2 im Grundriß dargestellten Preßvorrichtung dar. Das mit den Leistenstücken 1, 2, 3 und 4 zu um leimende Holzteil 5 ist zwischen den Elektrodenplat ten 6 und 7 angeordnet, wobei dile Elektrodenplatte 7 nach Art eines Deckels aufklappbar ausgebildet sein soll. Bei zugefahrener Presse (Fig. 1) werden die ringsherum angeordneten Druckzulagen 8 und 9 mit Hilfe eines z. B. mit gasförmigen oder flüssigen Mediums aufblähbaren Druckelemente 10 ,und 11 gegen die Furnierleisten 1 bis 4 gepreßt, wobei zu beachten ist daß die an den Stoßstellen der Furnierleisten liegenden Druckelemente 9 erst später, d. h. nach dem Pas sendschnei den der Leistenüberlappungsstellen, mit Druck beaufschlagt werden. Das Passendschneiden erfolgt vorteilhafterweise von Hand durch Aufklappen des an jeder Stoßstelle angeordneten Elektrodenteiles 12, Aushängen der entsprechenden Druckzulage 9 und dann durcheinen einzigen Sägeschnitt durch die beiden sich überlappenden Enden zweier Furnierleisten. Erst nach diesem Vorgang wird die entsprechende Druckzulage 9 wieder eingehängt, das Elektrodenteil 12 wieder zugeklappt und dadurch der Hochfrequenz-Stromkreis über Endschalter geschlossen sowie das bzw. die entsprechnden Druckelemente mit Druck beaufsehlagt. Nach verhältnismäßig kurzer Zeit ist der im Hochfrequenzfeld durchgeführte Umleimungsvorgang beendet, so daß das Druckmedium der Drud<-elemente 10 und 11 wieder abgelassen werden kann. Fig. 1 shows a section along the line A-B in Fig. 2 in The pressing device shown in plan. That with the strip pieces 1, 2, 3 and 4 to be glued wooden part 5 is arranged between the electrode plates 6 and 7, wherein the electrode plate 7 can be opened in the manner of a cover target. When the press is closed (Fig. 1), the pressure supplements arranged around it are 8 and 9 with the help of a z. B. inflatable with gaseous or liquid medium Pressure elements 10, and 11 pressed against the veneer strips 1 to 4, which should be noted is that the pressure elements 9 lying at the joints of the veneer strips only later, d. H. after the cut of the groin overlap, with pressure be applied. The fitting cutting is advantageously carried out by hand Unfolding the electrode part 12 arranged at each joint, unhooking the corresponding pressure allowance 9 and then by a single saw cut through the two overlapping ends of two veneer strips. Only after this process If the corresponding pressure support 9 is attached again, the electrode part 12 again Folded shut and thereby the high-frequency circuit is closed via limit switches as well as that or the corresponding pressure elements are subjected to pressure. According to proportionately The banding process carried out in the high-frequency field is completed in a short time, so that the pressure medium of the Drud elements 10 and 11 are drained again can.

Hierbei werden die Druckzulagen 8 und 9 mit Hilfe der Gummiringe 13 über die Haken 14 in ihre ursprüngliche Lage zurückgebracht. Die Haken 14 sind vorteilhaft auf Laschen 15 und diese auf Gummigeweberiemen 16 zur Schonung der Druckelemente 10 und 11 befestigt. Die Druckzulagen 8 und 9 werden in dem vom Gut und den beiden überstehenden Rändern der Elektrodenplatten 6 und 7 gebildeten Spalt geführt, d. h., die Druckzulagen 8 und 9 müssen in jedem Falle dünner gewählt werden als das zu umleimende Gut 5.Here, the pressure supports 8 and 9 are secured with the aid of the rubber rings 13 returned via the hooks 14 to their original position. The hooks 14 are advantageous on tabs 15 and these on rubber fabric belts 16 to protect the printing elements 10 and 11 attached. The pressure supplements 8 and 9 are in the one of the good and the two protruding edges of the electrode plates 6 and 7 formed gap, d. In other words, the pressure layers 8 and 9 must be chosen thinner than that in any case Good to be glued 5.

Hierdurch wird außer dem Vorteil einer guten Führung der Druckzulagen noch der Vorteil erzielt, daß die Miterwärmung der Druckzulagen durch den zwischen den Druckzulagen und den Elektrodenplatten entstehenden Luftspalt stark herabgemindert und dadurch der Wirkungsgrad der Anlage erhöht wird.This also has the advantage of good guidance of the pressure supplements still achieved the advantage that the co-heating of the pressure supplements by the between the air gap created by the pressure supplements and the electrode plates is greatly reduced and thereby the efficiency of the system is increased.

Der Gegenstand der Erfindung ist nicht auf das Ausführunglispiel beschränkt, sondern er kann in mannigfacher Weise abgewandelt werden. So können die Druckzulagen nicht nur aus Holz sondern wenn dies aus Fertigkeitsgründen erforderlich sein sollte, auch aus anderen Stoffen, z. B. aus Vulkanfiber, mit oder ohne Metalleinlagen oder aus geschichteten Werkstoffen bestehen. Ferner können die Druckzulagen an ihrer Oberfläche, insbesondere an ihrer Auflagefläche mit Vorsprüngen versehen sein, um dadurch infolge des sich bildenden Luftspaltes die Miterwärmung der Drnckzulagen weiter zu vermindern. The subject of the invention is not limited to the exemplary embodiment limited, but it can be modified in many ways. So can the pressure supplements not only made of wood but if this is necessary for reasons of skill should also be made of other materials, e.g. B. made of vulcanized fiber, with or without metal inserts or consist of layered materials. Furthermore, the pressure supplements can be attached to their Surface, in particular be provided on its support surface with projections to as a result of the air gap that forms, the pressure allowances are also heated to decrease further.

Ebenso ist es möglich, an Stelle der Haken irgendwelche andere Haltemittel, beispielsweise Ketten, Seile od. dgl., zu verwenden. Schließlich können auch die zum Zurückziehen der Druckinlagen. dienenden Gummiringe durch andere bekannte Zugmittel, wie z. B. durch Zugfedern, ersetzt werden. It is also possible to use any other holding means instead of the hooks, For example, chains, ropes or the like. To use. Finally, the to withdraw the pressure inserts. serving rubber rings by other known traction means, such as B. be replaced by tension springs.
