Description

ExtruderExtruders

Die Erfindung betrifft einen Extruder «1t Vorratsbehälter für Granulat und einer Stopfschnecke für thermoplastischen Kunststoff.The invention relates to an extruder with a 1t storage container for granulate and a screw feeder for thermoplastic material.

TheraopTastIsche Kunststoffe werden üblicherweise Mittels Extrudern zu Platten, Folien, Bahnen, Rohrprofi1en oder anderen Profilen verarbeitet. Therapeutic plastics are usually processed using extruders into sheets, films, sheets, tubular profiles or other profiles.

Beim Extrudieren werden die Plaste durch Umsatz mechanische" Energie y in Wärme (Innere und äußere Reibung) plastifiziert. Oblicherwe.se wirdDuring extrusion, the plastics are plasticized by converting mechanical energy into heat (internal and external friction).

die mechanische Energie mittels Schnecken zugeführt. Es gibt Ein- : schneckenextruder; Doppelschneckenextruder, gleichlaufend oder gegen- &Idigr;. läufig. Es gibt vorteilhafte Sonderformen, z. B. den Planetwalzen- % extruder.The mechanical energy is supplied by means of screws. There are single-screw extruders; twin-screw extruders, co-rotating or counter -rotating . There are advantageous special forms, e.g. the planetary roller extruder.

Allen Schneckenextrudern ist gemeinsam, daß die üblicherweise horizon- % tal angeordnete Schnecke in ihrem Gehäuse in Schneckenförderrichtung hinten mit dem Antrieb versehen ist und vorne ein Werkzeug besitzt, mit dem je nach Bestimmung Platten, Folien geformt werden.What all screw extruders have in common is that the screw, which is usually arranged horizontally , is fitted with a drive at the rear of its housing in the screw conveying direction and has a tool at the front with which sheets or films are formed, depending on the purpose.

Das Material wird in der Regel als Granulat mit einem Trichter aufgegeben, der über der Schnecke angeordnet 1st. Aus dem Trichter bzw. % Vorratsbehälter läuft das Granulat in die Schnecke.The material is usually fed in as granules using a hopper that is positioned above the screw. The granules flow from the hopper or storage container into the screw.

; Es 1st üblich, mit dem Granulat auch kleingehäckseite Abfälle, Insbesondere Randstrelfen aus dem Besäumen von extrudierter Bahnenware aufzugeben. Allerdings verhalten sich die kleingahäckselten Abfälle 1m Vorratstrichter anders als das Granulat. Es kann deshalb zu unerwünschten Ausmischungen können. Nacn einem älteren Vorschlag 1st deshalb vorgesehen, die Abfälle separat zum Granulat mit Hilfe einer : Stopfschnecke unMittel bar der Schnecke des Extruders aufzugeben. Das bringt jedoch andere Verfahrensprobleme mit sich. Der Erfindung Hegt daher die Aufgabe zugrunde, die Aufgabe der kltingehickseiten Abfälle einschl. Randstrelfen zu vereinfachen. Nach der Erfindung wird das r- dadurch erreicht, daß für die Material aufgäbe aus dem Vorratsbehälter ; eine Stcpfschnecke vorgesehen 1st und die das Abfallmaterial zuführende weitere Schnecke an die Stopfschnecke angeschlossen ist.; It is usual to feed small chopped waste, particularly edge strips from the trimming of extruded web material, with the granulate. However, the small chopped waste behaves differently in the storage hopper than the granulate. This can lead to undesirable mixing. According to an older proposal, the waste is therefore fed separately from the granulate using a stuffing screw directly into the extruder screw. However, this brings with it other process problems. The invention is therefore based on the object of simplifying the feeding of the small chopped waste including edge strips. According to the invention, this is achieved in that a stuffing screw is provided for the material feed from the storage container ; and the further screw feeding the waste material is connected to the stuffing screw.

Die weitere, material zuführende Schnecke kann verschiedenste Bauformen besitzen. Für den Extruder 1st es von Vorteil, wenn dieser als Planetwalzenextruder ausgeführt 1st.The additional screw that feeds the material can have a variety of designs. It is advantageous for the extruder to be designed as a planetary roller extruder.

In der Zeichnung 1st ein Ausführungsbeispiel der Erfindung dargestellt. The drawing shows an embodiment of the invention.

MU 1 sind die schematisch dargestellte Schnecke und Schneckengehäuse eines Planetwalzenextruders bezeichnet. Der Planetwalzenextruder besitzt eine zentrisch angeordnete und umlaufende Schnecke. Die zentrisch angeordnete Schnecke kämmt mit verschiedenen anderen als Planeten um die zentrisch angeordnete Schnecke herumlaufenden weiteren Schnecken, Die weiteren Schnecken kämmen Ihrerseits mit dem innenseitig verzahnten Schneckengehäuse.MU 1 is the schematically shown screw and screw housing of a planetary roller extruder. The planetary roller extruder has a centrally arranged and rotating screw. The centrally arranged screw meshes with various other screws that rotate as planets around the centrally arranged screw. The other screws in turn mesh with the internally toothed screw housing.

An den Planetwalzenextruder 1 1st eine Stopfschneckc 2 angeschlossen. Die Stopfschnecke 2 steht vertikal auf dem horizontal verlaufenden Extruder 1. Die Stopfschnecke 2 zieht Granulat, auf einem Vorratsbehälter ab. über die Drehzahl der Stopfschnecke läßt sich die Material aufgäbe genau einstellen.A stuffing screw 2 is connected to the planetary roller extruder 1. The stuffing screw 2 is positioned vertically on the horizontally running extruder 1. The stuffing screw 2 draws granulate into a storage container. The material feed rate can be precisely adjusted using the speed of the stuffing screw.

An die Stopfschnecke 2 ist ein Doppelschneckenextruder 4 angeschlossen. Der Doppelschneckenextruder besitzt zwei gegenläufig zueinander drehende Schnecken. Zum Schneckenantrieb sind ein Getriebe 5, Kupplung 6 und Elektrogetriebemotor 7 vorgesehen.A twin-screw extruder 4 is connected to the stuffing screw 2. The twin-screw extruder has two screws that rotate in opposite directions. A gear 5, coupling 6 and electric gear motor 7 are provided to drive the screws.

Das Gehäuse der Doppel schnecke 4 1st bei 8 ausgenommen, so daß zwischen die Schnecken Abfälle, hier Randstreifen, aufgegeben werden können.The housing of the double screw 4 1 is removed at 8 so that waste, here edge strips, can be fed between the screws.

Die Randstreifen fallen bei der Herstellung von Bahnenware an, die mit Hilfe des Extruders 1 hergestellt wird. Dabei wirkt der Extruder 1 in ein nicht dargestelltes Werkzeug, aus dem ein Material strang zwischen zwei Kalanderwalzen aufgegeben wird, der bereits in etwa die Breite der gewünschten Bahnenbreite besitzt. Zwischen den den Extruder nachgsschaltetsn, nicht dargestellten Kalanderwalzen wird de« Material eine definierte Dicke gegeben. Dabei stellen sich nicht definierte Breiten ein. Deshalb wird die aus den Kalandern austretende BahnenwareThe edge strips are produced during the production of web material, which is produced with the help of the extruder 1. The extruder 1 acts in a tool (not shown) from which a strand of material is fed between two calender rolls, which already has approximately the width of the desired web width. The material is given a defined thickness between the calender rolls (not shown) connected downstream of the extruder. This results in undefined widths. Therefore, the web material emerging from the calenders is

vor dem Aufwickeln auf Rollen besäumt. Dazu eignen sich scheibenförmige, sich drehende Messer, Die anfallenden Bahnenstreifen werden der Doppel schnecke 4 zugeführt. Das kann z. B. über Rollenführungen erfolgen, wenn der Anfang von Hand 1n den Extruder geführt wird und sichergestellt 1st, daß die Randstrelfen nicht abreißen. Dann zieht der Extruder die Randstreifen von alleine nach. Zur Führung der Randstrelfen eignen sich auch beliebige andere Transporteinrichtungen, z. B. Transportbänder.trimmed before winding onto rolls. Disc-shaped, rotating knives are suitable for this. The resulting web strips are fed to the double screw 4. This can be done, for example, via roller guides if the beginning is guided into the extruder by hand and it is ensured that the edge strips do not tear off. The extruder then pulls the edge strips along automatically. Any other transport devices are also suitable for guiding the edge strips, e.g. conveyor belts.
