Abstract
Description
PlattenoresseRecord fair
Die vorliegende Erfindung betrifft eine Plattenpresse mit einer durch einen Druckzylinder beaufschlagbaren unteren Heizpressplatte und einer ebenfalls durch einen Druckzylinder beaufschlagbaren oberen Heizpressplatte.The present invention relates to a platen press with a through a pressure cylinder pressurized lower heating press plate and also one by a pressure cylinder pressurized upper heating press plate.
Man presst in Plattenpressen dieser Art sehr lange Sperrhölzer, sogar bis 24 m lang, Platten oder verschiedenartige Sperrholzbalken. Die Erfindung bezweckt das Hervorbringen einer Plattenpresse von neuem Typ und mit einer Bauweise von geringerem Gewicht, den zuvor bekannten Plattenpressen gegenüber. Die erfindungsgemässe Plattenpresse ist dadurch gekennzeichnet, dass zwischen den Pressplatten eine Heizplatte starr abgestützt ist. Wenn man den Pressvorgang einleitet, hält man zum Beispiel die obere Pressplatte mit einer bestimmten Kraft gegen die Heizplatte angedrückt und man führt den zu pressenden Furnierstoss zwischen der Heizplatte und der unteren Pressplatte ein. Man presst die untere Pressplatte mit einer bestimmten Kraft an den Stoss an, wonach der Stoss vermöge der Wärme verleimt wird und zugleich der Pressdruck abfällt. Sobald der Pressdruck bei der halben Höhe angelangt ist, hebt man die obere Pressplatte an, führt einen Furnierstoss in den Zwischenraum ein, schliesst diesen und fährt dann mit den Pressphasen in oben beschriebener Weise in Abwechslung fort. Somit gibt die zwischenliegende Heizplatte sowohl an den darUberliegenden als auch an den darunterliegenden Stoss Wärme ab. Die Heizplatte ist ausserordentlich dAnn, da gegen dieselbe dauernd zu Beginn der Pressphasen Gegenkräfte wirken.In panel presses of this type, you press very long plywood, even up to 24 m long, panels or various types of plywood. The invention aims the creation of a platen press of a new type and of a lesser construction Weight compared to the previously known plate presses. The platen press according to the invention is characterized in that there is a rigid heating plate between the press plates is supported. For example, when you start the pressing process, you hold the upper one Press the press plate with a certain force against the heating plate and guide the veneer joint to be pressed between the heating plate and the lower pressing plate a. The lower press plate is pressed against the joint with a certain force, after which the joint is glued by virtue of the heat and at the same time the pressure drops. As soon as the pressing pressure is halfway up, the upper pressing plate is lifted on, introduces a joint of veneer into the gap, closes it and moves then alternate with the pressing phases in the manner described above. Consequently indicates the intermediate heating plate both on the overlying and the underlying shock dissipates heat. The heating plate is extremely thin, since opposing forces act against it continuously at the beginning of the pressing phases.
Die Erfindung wird im folgenden mit Hilfe eines Beispiels mit Hinweis auf die beiliegende Zeichnung beschrieben, worin Fig. 1 die Plattenpresse in der Seitenansicht darstellt.The invention is cited below with the aid of an example to the accompanying drawing, wherein Fig. 1 shows the platen press in the Side view represents.
Fig. 2 gibt den Schnitt längs der Linie I1-II in Fig. 1 wieder.FIG. 2 shows the section along the line I1-II in FIG.
Fig. 3 veranschaulicht graphisch die Pressphasen, auf die Zeitachse bezogen.3 graphically illustrates the pressing phases, on the time axis based.
Die Plattenpresse setzt sich aus einer Mehrzahl von aufeinanderfolgenden ringförmigen Gestellteilen 1 zusammen, die eine durch Druckzylinder 2 beaufschlagbare untere Heizpressplatte Bund eine gleichfalls durch Druckzylinder 4 beaufschlagbare obere Heizpressplatte 5 besitzen. Zwischen den Heizplatten ist eine Heizplatte 6 starr abgesetzt. Die Pressphasen 7 der Pressplatten 3,5 sind abwechselnd stattfindend angeordnet, wie in Fig. 3 dargestellt ist. Die Offenzeiten der Pressspalte der Platten 3,5 sind in dem Zeitdiagramm mit 8 bezeichnet. Die Pressdrücke zwischen den Pressplatten und der Heizplatte sind mit gestrichelten Linien v angezeigt.The platen press is composed of a plurality of consecutive annular frame parts 1 together, which can be acted upon by a pressure cylinder 2 Lower heating press plate federal government also acted upon by pressure cylinder 4 Have upper press heating plate 5. A heating plate 6 is located between the heating plates rigidly set off. The pressing phases 7 of the pressing plates 3, 5 take place alternately arranged as shown in FIG. The open times of the press nips of the panels 3, 5 are denoted by 8 in the timing diagram. The pressing pressures between the pressing plates and the heating plate are indicated with dashed lines v.
Es ist dem Fachmann einleuchtend, dass sich die Erfindung nicht auf die obenstehend dargestellten Beispiele einschränkt und dass sie vielmehr im Rahmen der nachstehenden Patentansprüche variieren kann.It is obvious to the person skilled in the art that the invention does not apply the examples shown above and that they are rather within the scope of of the following claims may vary.
