Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Formteilen aus Schaumstoff-Partikeln nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for producing molded parts of foam particles according to the preamble of claim 1.
Partikelschaumstoffe sind seit langer Zeit bekannt und haben sich auf vielen Gebieten bewährt. Die Herstellung derartiger Schaumstoffe erfolgt durch Aufschäumen von mit Treibmitteln imprägnierten Schaumstoff-Partikel und nachfolgendem Verschweißen mittels Heißdampf der so hergestellten Schaumpartikel zu Formteilen bzw. Formkörpern. Die Schaumstoff-Partikel bestehen beispielsweise aus EPS (expandiertes Polystyrol), EPE (expandiertes Polyethylen), EPP (expandiertes Polypropylen) oder Copolymerisaten.particle foams have been known for a long time and have many fields proven. The Production of such foams is carried out by foaming foam particles impregnated with blowing agents and subsequent weld together by means of superheated steam the foam particles thus produced to form parts or moldings. The foam particles consist for example of EPS (expanded polystyrene), EPE (expanded polyethylene), EPP (expanded polypropylene) or copolymers.

Für manche Anwendungszwecke ist es jedoch unerlässlich, dass die Formteile eine gleichmäßige Dichteverteilung aufweisen. So werden zum Beispiel im Bauwesen nur Dämmplatten mit einer gleichmäßigen Dichteverteilung als normgerecht zugelassen.For some However, it is imperative that the molded parts a uniform density distribution exhibit. For example, in construction, only insulation boards are used with a uniform density distribution approved as standard.
Ausgehend von diesem Stand der Technik besteht somit eine Aufgabe darin, eine Vorrichtung zu schaffen, mit der aus Schaumstoff-Partikeln Formteile hergestellt werden können, die über das Volumen der Formteile eine zumindest weitgehend gleichmäßige Dichteverteilung aufweisen.outgoing There is thus an object of this prior art, a Device to create with the foam particles molded parts can be produced the above the volume of the moldings an at least substantially uniform density distribution exhibit.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in weiteren Ansprüchen definiert.These The object is achieved by a device having the features of the claim 1 solved. Advantageous embodiments The invention are defined in further claims.
Die Vorrichtung zur Herstellung von Formteilen aus Schaumstoff-Partikeln weist eine Form und einen mit zu plastifizierenden und zu verschweißenden Schaumstoff-Partikeln befüllbaren Schäumraum auf. Das Volumen des Schäumraums ist verringerbar. Der Schäumraum weist Formteilzonen auf, die in Richtung der Volumenreduzierung unterschiedlich tief ausgebildet sind. Zur Volumenreduzierung sind an der Vorrichtung mindestens zwei relativ zueinander verschiebbare Pressflächen vorgesehen. Den Pressflächen liegt in Vorschubrichtung jeweils mindestens eine Formteilzone gegenüber. Die Hubwege, die von den Pressflächen bei der Hubbewegung nach innen jeweils zurückgelegt werden, sind abhängig von der Tiefe der den Pressflächen jeweils gegenüberliegenden Formteilzonen festlegbar. Unter Formteilzonen sind in diesem Text die Bereiche des Schäumraums zu verstehen, die vom herzustellenden Formteil nach der Verdichtung im Schäumraum eingenommen werden. Beispielweise kann es sich bei dem herzustellenden Formteil um Fußbodenheizungsplatten handeln. Jedoch bestehen hinsichtlich der Abmaße und der Gestalt der herzustellenden Formteile grundsätzlich keinerlei Einschränkungen. Selbstverständlich ist es denkbar, mehr als zwei Pressflächen vorzusehen.The Device for the production of molded parts from foam particles has a Mold and a foam particles to be plasticized and welded fillable Foam room on. The volume of the foam chamber is reducible. The foaming room has molding zones that are in the direction of volume reduction are formed differently deep. For volume reduction are on the device at least two relatively displaceable pressing surfaces intended. The pressing surfaces lies in the feed direction in each case at least one molding zone opposite. The Stroke paths coming from the pressing surfaces in each case are covered in the stroke movement, depend on the depth of the pressing surfaces opposite each other Shaping zones can be specified. Below molding zones are in this text the areas of the foaming room to understand the molded part to be produced after compaction taken in the foaming room become. For example, it may be in the molded part around underfloor heating panels act. However, in terms of the dimensions and the shape of the molded parts to be produced exist in principle no restrictions. Of course it is it is conceivable to provide more than two pressing surfaces.
Bei einer speziellen Ausgestaltung der Erfindung sind die Pressflächen auf einer Seite der Form angeordnet und die Pressflächen sind in vor der Hubbewegung eingenommenen Ausgangsstellungen in Bewegungsrichtung der Pressflächen zueinander versetzt anordenbar, wobei die Hubwege der Pressflächen proportional zur Tiefe der den Pressflächen jeweils zugeordneten Formteilzonen festlegbar sind.at a special embodiment of the invention, the pressing surfaces arranged one side of the mold and the pressing surfaces are in front of the lifting movement taken starting positions offset in the direction of movement of the pressing surfaces to each other can be arranged, wherein the strokes of the pressing surfaces proportional to the depth the pressing surfaces respectively assigned mold part zones can be fixed.
Gemäß einer besonders vorteilhaften Ausführungsform können die Pressflächen in den Ausgangsstellungen derart angeordnet werden, dass der Schäumraum vor der Volumenreduzierung eine bezüglich einer senkrecht zur Richtung der Volumenreduzierung angeordneten Mittelebene spiegelsymmetrische Innenkontur aufweist.According to one particularly advantageous embodiment can the pressing surfaces be arranged in the initial positions such that the foaming space before the volume reduction a re one arranged perpendicular to the direction of volume reduction Center-level mirror-symmetrical inner contour has.
Bei einer weiteren Ausführungsform sind die Pressflächen auf zwei verschiedenen Seiten der Form angeordnet, wobei die Pressflächen die Form in Richtung der Volumenreduzierung beidseits nach außen begren zen, und wobei einander gegenüberliegende Pressflächen aufeinander zu bewegbar sind.In another embodiment, the pressing surfaces on two different sides of the Form arranged, wherein the pressing surfaces zen the shape in the direction of the volume reduction on both sides outside zen, and wherein opposing pressing surfaces are movable towards each other.
Beispielsweise ist mindestens eine der Pressflächen unabhängig von anderen Werkzeugzonen beheizbar.For example is at least one of the pressing surfaces independently heated by other tool zones.
Bei einer Ausführungsform ist mindestens eine von den Pressflächen jeweils gegenüberliegenden Querflächen beheizbar.at an embodiment is at least one of the pressing surfaces respectively opposite transverse surfaces heated.
Vorzugsweise ist die durch das Schmelzen des an den beheizten Flächen anliegenden Schaumstoffs resultierende Volumenreduzierung durch Schaumstoffpartikel kompensierbar, die dem Schäumraum aus einer Vorratszone zugeführt werden können.Preferably is that due to the melting of the voltage applied to the heated surfaces Foam resulting volume reduction by foam particles Compensable to the foam chamber supplied from a supply zone can be.
Vorzugsweise erfolgt die Bewegung der Pressflächen geradlinig und die Bewegungsvektoren der Pressflächen sind parallel zueinander ausgerichtet.Preferably the movement of the pressing surfaces takes place straight line and the motion vectors of the pressing surfaces are parallel to each other aligned.
Mit der erfindungsgemäßen Vorrichtung lässt sich im Vergleich zum Stand der Technik eine wesentlich homogenere Dichteverteilung über das Volumen der Formteile erreichen. Die erfindungsgemäße Vorrichtung erlaubt es, bei der Herstellung der Formteile Dampf und Rohmaterial einzusparen und die Zykluszeit im Vergleich zum Stand der Technik zu verkürzen.With the device according to the invention let yourself Compared to the prior art, a much more homogeneous density distribution over the Reach volume of the moldings. The device according to the invention allows steam and raw material in the production of molded parts save and the cycle time compared to the prior art To shorten.
