Abstract

The baling press for fibrous material which may be damp, with two pressure boxes carried by a turntable, as in the main patent, has the two boxes guided along a restricted part of the main surface, then lifted to a crossing part of the frame into the pressing position. The interval surfaces of these pressure boxes are covered by a friction reducing layer of pref. high molecular low density polyethylene or polyamide material. This material can be in the form of plates which are secured by screws to the steel walls of the pressure boxes.

Description

Ballenpresse, insbesondere für langfaseriges GutBaling press, especially for long-fiber goods

Zusatz zu Patent ... (Pat.Anm. P 29 10 536.0) Die Erfindung bezieht sich auf eine Weiterentwicklung der Ballenpresse nach dem Hauptpatent.Addendum to patent ... (Pat.Anm. P 29 10 536.0) The invention relates on a further development of the baling press according to the main patent.

In dieser Lehre wird eine Ballenpresse vorgeschlagen, bei der zwei Preßkästen mittels einer Karussellanordnung um eine zwischen ihnen befindliche vertikale Rotationsachse aus einer Vorpreß- in eine Fertigpreßstation und umgekehrt bewegbar sind, wobei die Längsachsen der Grundflächen der beiden Preßkbsten Ubereinstimmend durch die Rotationsachse verlaufen und der Rahmen der Ballenpresse eine schmale, die Kontur der Preßkästen nur geringfügig überschreitende Grundfläche aufweist, und daß am oberen Querjoch des Rahmens im Bereich der Fertigpreßstation eine Hubvorrichtung zum Anheben des in dieser Station befindlichen, ungeteilt ausgebildeten Preßkastens bis über den gepreßten Ballen unter Aufrechterhaltung des Preßdruckes vorgesehen ist.In this teaching, a baler is proposed in which two Press boxes by means of a carousel arrangement around a vertical one located between them The axis of rotation can be moved from a pre-press station to a final press station and vice versa are, the longitudinal axes of the bases of the two Preßkbsten coinciding run through the axis of rotation and the frame of the baler has a narrow, the contour of the press boxes only slightly exceeds the base area, and that a lifting device on the upper cross yoke of the frame in the area of the finishing press station for lifting the undivided press box located in this station provided over the pressed bale while maintaining the pressure is.

Preßkästen nach dem Stand der Technik und nach dem Hauptpatent werden Ublicherweise aus Stahl hergestellt. Die Arbeiten mit dem Gegenstand des Hauptpatentes haben nur zu der Beobachtung geführt, daß beim Abziehen des einzelnen Preßkastens vom gepreßten und unter anhaltendem Preßdruck stehenden Ballen Schwingungen entstehen, die sich in einer raiternden Bevegung bemerkbar machen. Außerdem wurde eine konische oder keilförmige Ballenbildung nach dem Abziehen der Preßkästen beobachtet.Press boxes according to the state of the art and according to the main patent Usually made of steel. Work on the subject of the main patent have only led to the observation that when pulling off the individual press box vibrations arise from the pressed bale under sustained pressing pressure, which make themselves felt in a raiding movement. There was also a conical or wedge-shaped bale formation observed after peeling off the press boxes.

Diese Auswirkungen zu vermeiden, ist Aufgabe der zusätzlichen Erfindung.It is the object of the additional invention to avoid these effects.

Uberraschenderweise konnten diese Erscheinungen vermieden werden, wenn erfingungsgemäß die Innenfläche der Preßkästen mit einer reibungsarmen Schicht, insbesondere aus hochmolekularen Niederdruckpolyäthylen oder Polyamid, ausgekleidet ist, wobei es sich empfiehlt, die reibungsarme Schicht aus Platten zu bilden, die an die Wände der aus Stahl bestehenden Preßkästen angeschraubt sind.Surprisingly, these phenomena could be avoided, if according to the invention the inner surface of the press boxes with a low-friction layer, in particular made of high molecular weight low-pressure polyethylene or polyamide, lined is, whereby it is advisable to form the low-friction layer from plates that are screwed to the walls of the steel press boxes.

Die Auskleidung läßt sich auch mit Vorteil bei solchen Preßkästen anwenden, die noch anderen Prinzipien als denen der Erfindung konzipiert sind.The lining can also be used to advantage in such press boxes apply which are devised of principles other than those of the invention.

Der Vorteil der Erfindung ergibt sich nicht allein daraus, daß Kunststoff einen geringeren Reibungswiderstand als Stahl aufweist.The advantage of the invention does not arise solely from the fact that plastic has a lower frictional resistance than steel.

Maßgeblich ist vielmehr, daß die Differenz zwischen dem HaftreibungsfaktoryuO und dem Geitreibungsfaktorft bei Stahl wesentlich höher als bei Kunststoff, insbesondere bei den genannten Kunststoffsorten, ist. Die Differenzverminderung ist ursächlich für das Vermeiden von Schwingungen und Ratterbewegungen der Preßkästen und ihrer Hubantriebe beim Abziehen vom gepreßten Ballen.Rather, it is decisive that the difference between the static friction factor uO and the coefficient of sliding friction in steel is significantly higher than in plastic, in particular in the types of plastic mentioned. The difference reduction is causal for avoiding vibrations and chattering movements of the press boxes and their Lift drives when pulling off the pressed bale.

Zugleich wird mit der Erfindung eine dem Innenraumder Preßkästen genauer entsprechende Formgebung der gepreßten Ballen erzielt.At the same time, with the invention, one of the interior of the press boxes becomes more accurate corresponding shaping of the pressed bales achieved.

Die nach der Erfindung hergestellten Preßkdsten weisen auch eine größere Unempfindlichkeit gegen Verschmutzungen beim Pressen ungewaschener Wolle auf. Selbst das Pressen feuchten Maiiials bereitet keine Schwierigkeiten, wohingegen bei Preßkästen aus unbeschichtetem Stahl die Feuchtigkeit zu einer wesentlichen Steigerung des Gleitreibungsfaktors und danit zur Verstärkung der Schwingungen führen würde.The Preßkdsten produced according to the invention also have a larger one Insensitivity to soiling when pressing unwashed wool. Self pressing moist maizeials does not present any difficulties, whereas pressing boxes do made of uncoated steel the moisture to a substantial increase of the Sliding friction factor and danit for reinforcement of the vibrations would lead.

Schließlich ergibt aus der Anwendung der Erfindung ebe höhere Enddichte des Ballens bei gleicher Preßkraft und eine geringere Kastenabzugskraft.Finally, the application of the invention also results in higher final density of the bale with the same pressing force and a lower box pull-off force.
