Description

Verfahren und Ifaschine zum Trocknen und Glätten von Furnieren Bei dem Verfahren zum -Trocknen und Glätten von Furnieren nach der Erfindung werden die Furniere zwischen beheizten- Walzen hindurchgeschickt, die von Gruppe zu Gruppe mit immer höher ansteigendem Druck gegeneinander anliegen. Die Maschine zum Trocknen und Glätten von Furnieren nach der Erfindung besteht aus mehreren in senkrechten und waagerechten Reihen angeordneten, angetriebenen und geheizten Walzen, deren Lager bis auf die untersten senkrecht be«-eglidi sind.Method and machine for drying and smoothing veneers Bei the method for drying and smoothing veneers according to the invention the veneers are passed between heated rollers, which are passed from group to group abut against each other with increasing pressure. The machine for drying and smoothing of veneers according to the invention consists of several in vertical and horizontal rows arranged, driven and heated rollers, their Bearings are vertical except for the lowest.

Das neue "erfahren zeigt folgende Vorteile: Der Trockenvorgang geht schnell und kräftig vor. sich, da Trockengut und Trockenwalze in. stetig wechselndem Kraftschluß sind. Dieser Vorgang gewährleistet eine gute Wärmeübertragung, dadurch bedingt, daß Sehwaden sich nicht mehr zwischen dem Trockengut und der Trockenwalze halten können.The new "experience" shows the following advantages: The drying process works quickly and vigorously. because the material to be dried and the drying roller are constantly changing Are frictional. This process ensures good heat transfer, thereby requires that the visual calves are no longer between the material to be dried and the drying roller can hold.

Die Maschine arbeitet ohne Unterbrechung und ohne Bedienung. Der Trockenvorgang kann dauernd überwacht werden. Materialzerstörungen und -verletzungen sind ausgeschlossen, weil das Trockengut mit zunehmender Beanspruchung auch widerstandsfähiger wird.The machine works without interruption and without operation. The drying process can be monitored continuously. Material destruction and damage are excluded, because the dry goods also become more resistant with increasing use.

Die Maschine ist in den Zeichnungen beispielsweise dargestellt.The machine is shown in the drawings as an example.

Abb. i ist eine schematische Darstellung. Abb. a und 3 zeigen in Aufriß und Grundriß die Ausführung der -Maschine.Fig. I is a schematic representation. Fig. A and 3 show in elevation and ground plan the execution of the machine.

In mehreren senkrechten, voneinander durch Zwischenräume getrennten Reihen- sind Walzen b bis m im Rechteck angeordnet. Nur die untersten Walzen g, k, 1, m, i jeder Reihe sind in Lagern gelagert, die sich in senkrechter Richtung nicht verschieben können. Die übrigen Walzen sind in Lagern drehbar, die in senkrechter Richtung geführt sind. Die oberen Walzen ruhen daher auf den unteren Walzen, so daß der Druck, mit dem die `Valzen gegeneinander anliegen, von einer waagerechten Reihe zur anderen immer höher ansteigt. Die Walzen sind geheizt, und zwar dienen gelenkige und, wenn nötig, ausziehbare Glieder p zur Führung des Wärmeträgers von einer Walze zur nebenliegenden, während Schläuche den Wärmeträger von einer waagerechten Reihe zur andern leiten. Der Wärmeträger wird je an einem Walzenende zu-, am andern Walzenende abgeleitet, vorzugsweise derart, daß der Wärmeträger im Gegenstrom zum Arbeitsgut, also im Sinne des Pfeiles n (Abb. 1)3 fließt. Rollers b to m are arranged in a rectangle in several vertical rows separated from one another by spaces. Only the lowest rollers g, k, 1, m, i of each row are stored in bearings that cannot move in the vertical direction. The other rollers are rotatable in bearings that are guided in the vertical direction. The upper rollers therefore rest on the lower rollers, so that the pressure with which the rollers rest against one another rises ever higher from one horizontal row to the other. The rollers are heated, and articulated and, if necessary, extendable members p are used to guide the heat transfer medium from one roller to the next, while hoses guide the heat transfer medium from one horizontal row to the other. The heat transfer medium is fed to one end of the roller and discharged at the other end of the roller, preferably in such a way that the heat transfer medium flows in countercurrent to the material to be worked, that is, in the direction of arrow n (Fig. 1) 3.

Jedem Walzengang ist eine Waagerechtfördervorrichtung, z. B. ein Rollgang a1, a'-', vor- und dem letzten Walzengang nachgeschaltet, z. B. der Rollgang n-3.Each roller conveyor is a horizontal conveyor, for. B. a roller table a1, a'- ', upstream and downstream of the last roller gear, z. B. the roller table n-3.

Die Walzen werden durch Zahnradgetriebe angetrieben, derart, daß ein Zahnrad durch Riemen und Riemenscheibe angetrieben wird und von ihm aus alle Walzen durch ineinandergreifende Stirnräder bewegt werden. Besondere Kettentriebe dienen zum Antrieb der Rollgänge a1, n-2 usw.The rollers are driven by gear trains, such that a Gear is driven by belt and pulley and from it all the rollers be moved by intermeshing spur gears. Special chain drives are used to drive the roller tables a1, n-2 etc.

Das Arbeitsgut wird im Sinne des. Pfeiles o (Abb. i) zwischen den Walzen hindurch und über die Rollgänge geleitet. Dabei gelangt es zuerst zwischen die minder schwer belasteten Walzen b-c bis h-d und dann zwischen immer schwerer belastete Walzen. Mit der Belastung steigt auch die Temperatur. Je weiter ein Werkstück gelangt, um sG-trocIdener und daher um so fester wird es. Es wird deshalb auch immer widerstandsfähiger gegen Druck und Temperatur. Die sich bildenden Schwaden haben reichlich Raum, zwischen den Walzen abzuziehen.The work is in the sense of. Arrow o (Fig. I) between the Rollers passed through and over the roller tables. It gets between first the less heavily loaded rollers b-c to h-d and then between increasingly heavier loaded rollers. The temperature rises with the load. The further a workpiece gets to sG-trocIdener and therefore the more solid it becomes. It will therefore always be more resistant to pressure and temperature. Have the plumes that form plenty of room to pull off between the rollers.
