Beschreibung  description
Die Erfindung betrifft einen Spinnbalken zur Herstellung von schmelzgesponnenen Filamenten nach dem Oberbegriff von Anspruch 1. The invention relates to a spinning beam for the production of melt-spun filaments according to the preamble of claim 1.
Die bekannten Spinnbalken weisen Spinndüsenpakete auf, die reihenförmig an der Unterseite des Spinnbalkens angeordnet sind. Je nach Größe der Anlage werden mehrere Spinnbalkenmodule fest nebeneinander angeordnet, die über Rohrleitungen für das Wärmeträgermedium fest miteinander verbunden sind. Der hohe Platzbedarf der nebeneinander angeordneten Spinnbalkenmodule ist von der Montagesituation der Heizstäbe und Pumpe abhängig, die nur unter großem Aufwand gewartet und ggf. getauscht werden können, da hierfür ausreichend Platz zwischen den Spinnbalkenmodulen vorhanden sein muss. Eine Anpassung an eine vergrößerte Anlagenkapazität ist nur mit großem Aufwand möglich. The known spinning beams have spinneret packs which are arranged in rows on the underside of the spinneret. Depending on the size of the system several spin-beam modules are arranged firmly next to each other, which are firmly connected to each other via pipes for the heat transfer medium. The high space requirement of juxtaposed Spinnbalkenmodule depends on the mounting situation of the heating elements and pump, which can be maintained only with great effort and possibly replaced, as this sufficient space between the spinning beam modules must be present. An adaptation to an increased plant capacity is possible only with great effort.
Die EP 2122019 B1 offenbart eine Vorrichtung zum Schmelzspinnen synthetischer Elemente, bei dem die Spinnpumpe an einem separaten Pumpenträger angeordnet ist, der beabstandet vom Gehäuse des Spinnbalkens angeordnet ist. Es ergibt sich ein sehr großer Abstand zwischen der Pumpe und der Spinndüse, der mit dem technologischen Nachteil einer längeren Verweilzeit verbunden ist und aufgrund des Platzbedarfes eine mögliche Erweiterung der Anlage nur mit hohem Aufwand realisierbar macht. Aufgabe der vorliegenden Erfindung ist es, die bekannten Spinnbalken konstruktiv zu vereinfachen, einen erleichterten Zugang zur Wartung der Pumpe zu ermöglichen bei gleichzeitig kompakter Bauweise. EP 2122019 B1 discloses a device for melt-spinning synthetic elements, in which the spinning pump is arranged on a separate pump carrier, which is arranged at a distance from the housing of the spinning bar. This results in a very large distance between the pump and the spinneret, which is associated with the technological disadvantage of a longer residence time and makes a possible expansion of the system can be realized only with great effort due to the space required. Object of the present invention is to simplify the known spinning beam design, to allow easier access to the maintenance of the pump while compact design.
Die Aufgabe wird gelöst durch einen Spinnbalken zur Herstellung von schmelzgesponnenen Filamenten, bei dem über einen extern angeordneten Extruder flüssiger Kunststoff zu mindestens einer Pumpe gefördert wird, die den flüssigen Kunststoff zu mindestens einem Spinnpaket mit einer Spinndüse fördert, wobei zumindest die Pumpe und das Spinnpaket von einem Wärmeträgermedium beheizt werden, das in einem Boiler erhitzt wird. The object is achieved by a spinning beam for the production of melt-spun filaments, in which via an externally arranged extruder liquid plastic is conveyed to at least one pump, which promotes the liquid plastic to at least one spin pack with a spinneret, wherein at least the pump and the spin pack of a heat transfer medium to be heated, which is heated in a boiler.
Die Erfindung ist dadurch gekennzeichnet, dass die Pumpe, der Boiler und eine Öffnung zur Aufnahme eines Spinnpaketes in einer modularen Baugruppe angeordnet sind, die einzeln oder mehrfach hintereinander in einen Rahmen eines Spinnbalkens einsetzbar und befestigbar ist. The invention is characterized in that the pump, the boiler and an opening for receiving a spin pack are arranged in a modular assembly, which can be used and fastened one or more times in succession into a frame of a spinning beam.
Der Spinnbalken lässt sich damit beliebig um weitere Spinnpakete erweitern, wodurch die Anlagenkapazität sehr leicht einer steigenden Produktion angepasst werden kann. As a result, the spinning beam can be expanded to include additional spin packages, so that the capacity of the system can easily be adapted to increasing production.
Bevorzugt weist die modulare Baugruppe eine Aufhängung auf, die mindestens zwei Querträger umfasst. Die Querträger sind so dimensioniert, dass sie in den Rahmen des Spinnbalkens einsetzbar sind. An den Querträgern erfolgt der gesamte Aufbau der modularen Baugruppe. Preferably, the modular assembly has a suspension comprising at least two cross members. The cross members are dimensioned so that they can be used in the frame of the spinner. On the cross members, the entire structure of the modular assembly takes place.
Zu einer weiteren Verbesserung dient, dass die Querträger mit mindestens einer Wärmekammer derart verbunden sind, dass eine Öffnung zur Aufnahme mindestens eines Spinnpaketes gebildet wird. Die Querträger und die Wärmekammer bilden damit einen Rahmen, in dem die Öffnungen zur Aufnahme der Spinnpakete angeordnet sind. Die Verbindung der Querträger mit den Wärmekammern ergibt einen tragenden Rahmen, an dem alle anderen Bauteile der modularen Baugruppe befestigbar sind Serves for a further improvement that the cross member are connected to at least one heat chamber such that an opening for receiving at least one spin pack is formed. The cross member and the heat chamber thus form a frame in which the openings for receiving the spin packs are arranged. The connection of the cross member with the heat chambers gives a supporting frame to which all other components of the modular assembly can be fastened
Bevorzugt ist die Pumpe liegend und quer bzw. orthogonal zu einer Längsseite des Rahmens angeordnet. Damit kann die Pumpe von einem Betriebsgang des Gerüstes aus gewartet werden, ohne dass große Demontagearbeiten erforderlich sind. Preferably, the pump is lying and arranged transversely or orthogonal to a longitudinal side of the frame. Thus, the pump can be maintained from an operation of the scaffold without major disassembly work is required.
Eine weitere Verbesserung wird dadurch erreicht, dass der Boiler liegend und quer bzw. orthogonal zu einer Längsseite des Rahmens angeordnet ist. Beide Maßnahmen, nämlich die liegende Anordnung des Boilers und der Pumpe orthogonal zur Längsseite des Rahmens ermöglicht eine kompaktere Bauweise des Spinnbalkens, da für die Wartung beider Bauteile kein Platzbedarf zwischen den Spinnpaketen bzw. zwischen den Baugruppen erforderlich ist. Dies erfolgt ausschließlich am Bediengang des Gerüstes, der genug Platz für das Wechseln der langen Heizstäbe und der Pumpen aufweist. Insbesondere durch diese Anordnung des Boilers wird der Platzbedarf für die einzelnen Baugruppen verringert, wodurch mit einer geringeren Teilung auch die Leitungen für den flüssigen Kunststoff kürzer ausgelegt werden können. Die seitliche Anordnung des Boilers ermöglicht auch einen guten Zugang zur Pumpe und zur Monomerabsaugung. Der verfügbare Platz zwischen den Blasschächten wird für den Boiler genutzt, so dass keine zusätzliche Standfläche für einen separat stehenden Boiler auf der Stahlplattform erforderlich ist. Die Anordnung des Boilers ermöglicht eine geringe Teilung, da die Heizstäbe etwa 90° zur Spinnbalkenachse liegen. Die Pumpe und der Boiler müssen nicht exakt rechtwinklig zum Längsträger angeordnet sein. Auch eine leicht schräge Anordnung von beispielsweise 75° der Längsachse des Boilers und der Pumpe zum Längsträger, bei dem die Komponenten, beispielsweise die Heizstäbe, über den Bediengang ausgetauscht werden können, würde unter den Begriff quer bzw. orthogonal fallen. Beim Stand der Technik sind die Pumpe und der Boiler zwischen den Spinnpaketen demontierbar angeordnet, so dass der Abstand zwischen den Spinnpaketen durch den Demontageplatz der austauschbaren Komponenten bestimmt wird. Nach dieser Erfindung kann die Anordnung der Spinnbalken in einem sehr dichten Abstand zueinander erfolgen, was die Gesamtanlage kompakter macht und die Schmelze führenden Leitungen verkürzt, was den verfahrenstechnischen Vorteil der kürzeren Verweilzeit für den flüssigen Kunststoff bedeutet. A further improvement is achieved in that the boiler is arranged lying and transversely or orthogonal to a longitudinal side of the frame. Both measures, namely the horizontal arrangement of the boiler and the pump orthogonal to the longitudinal side of the frame allows a more compact design of the spinner, since no space requirement between the spinning packages or between the modules is required for the maintenance of both components. This is done exclusively at the operation of the scaffold, which has enough space for changing the long heating rods and the pumps. In particular, by this arrangement of the boiler, the space required for the individual modules is reduced, whereby the lines for the liquid plastic can be designed shorter with a smaller pitch. The lateral arrangement of the boiler also allows good access to the pump and to the monomer extraction. The available space between the blower ducts is used for the boiler, so that no additional floor space is required for a separate boiler on the steel platform. The arrangement of the boiler allows a small pitch, since the heating rods are about 90 ° to the spinning beam axis. The pump and the boiler do not have to be arranged exactly at right angles to the longitudinal member. Also, a slightly oblique arrangement of, for example, 75 ° of the longitudinal axis of the boiler and the pump to the side rail, in which the components, such as the heating elements, can be exchanged via the service gear would be among the Term transverse or orthogonal fall. In the prior art, the pump and the boiler between the spin packs are arranged removable, so that the distance between the spin packs is determined by the disassembly of the exchangeable components. According to this invention, the arrangement of the spinning beam can be done in a very close distance from each other, which makes the overall system more compact and shortens the melt-carrying lines, which means the procedural advantage of shorter residence time for the liquid plastic.
Bevorzugt wird die Pumpe mittels einer Welle von einem Antrieb angetrieben, wobei der Antrieb an einem Gerüst außerhalb des Spinnbalkens angeordnet ist. Durch die Demontage der Welle wird die Pumpe sehr leicht zugänglich und kann durch Lösen weniger Schrauben leicht demontiert werden. Preferably, the pump is driven by a shaft by a drive, wherein the drive is arranged on a frame outside of the spinning beam. By disassembling the shaft, the pump is easily accessible and can be easily disassembled by loosening a few screws.
Durch die Anordnung mehrerer modularer Baugruppen zu einem Spinnbalken, werden alle Boiler mittels Rohrleitungen mit einer Vakuumstation und einem Kondensor verbunden. Insbesondere dadurch, dass die Boiler mittels einer Rohrleitung miteinander verbunden sind, entsteht ein System kommunizierender Röhren, wodurch für jede modulare Baugruppe eine identische Heizsituation entsteht. By arranging several modular assemblies into a spinning beam, all boilers are connected by piping to a vacuum station and a condenser. In particular, the fact that the boilers are connected to each other by means of a pipe, creates a system of communicating tubes, creating an identical heating situation for each modular assembly.
Eine weitere Verbesserung wird dadurch erreicht, indem der flüssige Kunststoff über einen Flanschanschluss mittels mindestens einer Rohrleitung zu den Pumpen geleitet wird, wobei die Rohrleitungen fallend angeordnet sind. Damit können sich keine Ablagerungen von flüssigem Kunststoff unterschiedlicher Viskosität bilden. Die Ausführung ermöglicht im Unterschied zum Stand der Technik kurze Schmelzeleitungen mit entsprechend kurzen Verweilzeiten für den flüssigen Kunststoff. Die Erfindung wird anhand der beiliegenden Zeichnungen näher erläutert. In diesen zeigen A further improvement is achieved by the liquid plastic is passed via a flange connection by means of at least one pipe to the pump, wherein the pipes are arranged falling. Thus, no deposits of liquid plastic of different viscosity can form. The design allows in contrast to the prior art short melt lines with correspondingly short residence times for the liquid plastic. The invention will be explained in more detail with reference to the accompanying drawings. In this show

Der Antrieb 4 kann außerhalb des Rahmens 2 an einem Gerüst angeordnet sein, das den modular aufgebauten Spinnbalken 1 aufnimmt. Ebenfalls innerhalb des Spinnbalkens 1 ist ein Boiler 25 angeordnet, der beispielsweise Diphyl als Heizmedium aufnimmt. Zur Erwärmung des Wärmeträgermediums sind an dem Boiler 25 Öffnungen 26 angeordnet, in die Heizstäbe einschiebbar sind. Nach außen hin sind sowohl der Boiler 25 wie auch die Öffnungen 26 für die Heizstäbe durch jeweils eine Abdeckung 6, 7 verschlossen. Oberhalb des Spinnbalken 1 ist eine Vakuumstation 8 mit einem Kondensor 9 montiert, die über eine Rohrleitung 10 mit einer Wärmekammer 27a verbunden sind. Die Wärmekammer 27a korrespondiert mit mindestens einer weiteren Wärmekammer 27b, so dass die Spinndüsen mindestens von zwei Seiten umschlossen sind, wobei ein zirkulierender Kreislauf des Heizmediums zwischen der Vakuumstation 8, den Wärmekammern 27a, 27b und dem Boiler 25 entsteht. Sowohl der Kondensor 9 wie auch die Vakuumstation 8 sind mit ihren Nebenaggregaten am Spinnbalken 1 befestigt. Ein Wärmeträgermedium, beispielsweise Diphyl, wird innerhalb des Boilers 25 durch die Heizstäbe in einen dampfförmigen Zustand versetzt, so dass der Dampf die Wärmekammern 27a, 27b durchströmt. Ein innerhalb des Wärmekreislaufes auftretendes Kondensat wird über Kondensatleitungen zur Vakuumstation 8 und zum Kondensor 9 zurück geführt. FIG. 1 shows a modularly constructed spinning beam 1 which has a peripheral frame 2 on which all essential components are arranged or fastened. The frame 2 is formed from a circumferential U or double T-beam, in which a modular assembly 20a (Figure 2) can be suspended or used. The frame 2 is rectangular in construction and has two narrow sides 2a and two longitudinal sides 2b. Within the modular assembly 20a openings 23a, 23b, 23c are arranged for spin packs to be inserted, which can be closed by covers 3a, 3b, 3c and insulation, which are arranged on the frame 2. Outside the spinning beam 1, a drive 4 is arranged for a pump 24, wherein the drive 4 with the pump 24 via a shaft 5 is connectable. The pump 24 is arranged lying and transversely or orthogonal to the longitudinal side of the spinner 1 and promotes the liquid plastic through the nozzles of the spin packs. The drive 4 can be arranged outside the frame 2 on a scaffold, which accommodates the modularly constructed spinning beam 1. Also within the spinning beam 1, a boiler 25 is arranged, the For example, absorbs Diphyl as a heating medium. To heat the heat transfer medium 25 openings 26 are arranged on the boiler, in the heating elements can be inserted. Outwardly, both the boiler 25 and the openings 26 for the heating elements are each closed by a cover 6, 7. Above the spinning beam 1, a vacuum station 8 is mounted with a condenser 9, which are connected via a pipe 10 to a heat chamber 27a. The heat chamber 27a corresponds to at least one further heat chamber 27b, so that the spinnerets are enclosed at least from two sides, whereby a circulating circulation of the heating medium between the vacuum station 8, the heat chambers 27a, 27b and the boiler 25 is formed. Both the condenser 9 and the vacuum station 8 are attached with their ancillaries on the spinning beam 1. A heat transfer medium, for example Diphyl, is placed inside the boiler 25 by the heating elements in a vaporous state, so that the steam flows through the heat chambers 27a, 27b. A condensate occurring within the heat cycle is returned via condensate lines to the vacuum station 8 and to the condenser 9.
Figur 1 zeigt weiterhin einen Flanschanschluss 11 für eine Rohrleitung, über die von einem extern angeordneten Extruder flüssiger Kunststoff zur Pumpe 24 gefördert wird. Der Flanschanschluss 11 ist ebenfalls am Spinnbalken 1 befestigt und mittels Rohrleitungen 12 mit der Pumpe 24 und den Spinndüsen verbunden. Weiterhin weist der Spinnbalken 1 eine begehbare Oberfläche auf, unter der eine Isolierung 13 angeordnet ist. Die modulare Baugruppe 20a nach Figur 2 umfasst im Wesentlichen eine Aufhängung 21 , die mindestens zwei Querträger 21a, 21 b aufweist, zwischen denen die Wärmekammern 27a, 27b und die Öffnungen 23a, 23b, 23c für die Spinnpakete mit den Spinndüsen angeordnet sind. Es ist erkennbar, dass in diesem Ausführungsbeispiel der Spinnbalken 1 für drei Spinnpakete mit je einer Spinndüse ausgelegt ist, da jede Öffnung 23a, 23b, 23c ein Spinnpaket aufnehmen kann. Der Spinnbalken 1 kann aber auch nur für ein Spinnpaket, zwei Spinnpakete, oder für mehr als drei Spinnpakete konzipiert werden. In Längsrichtung des Spinnbalkens 1 sind also die Spinnpakete hintereinander angeordnet, um eine variable Anzahl von Spinnstreckanlagen zu erzeugen. Die Wärmekammern 27a, 27b sind integraler Bestandteil der Aufhängung 21 und verbinden die Querträger 21a, 21 b miteinander, so dass eine selbsttragende modulare Baugruppe 20a innerhalb des Spinnbalkens 1 entsteht. Damit das Wärmeträgermedium zirkulieren kann, sind die Wärmekammern 27a, 27b im Bereich der Querträger 21a, 21 b derart miteinander verbunden, dass die Spinnpakete auch an zwei weiteren Seiten, den Stirnseiten, gleichmäßig erwärmt werden. An den Querträgern 21a, 21b sind Auflagen 22a - 22d angeordnet, mit der die modulare Baugruppe 20a in den Rahmen 2 oder in ein Gerüst einhängbar ist. Auf der gegenüberliegenden Seite zu den Wärmekammern 27a, 27b ist am Querträger 21b der Boiler 25 liegend angeordnet. Hierzu sind in dem Ausführungsbeispiel Winkelprofile an einer Stirnseite an dem Querträgers 21a, 21 b angeordnet, an denen der Boiler 25 einstellbar befestigt wird. Der Boiler 25 ist liegend so platziert, dass die Öffnungen 26 für die Heizstäbe ohne weitere Demontage von einem Gang eines Gerüstes zugänglich sind. Dazu ist der Boiler 25 quer bzw. orthogonal zu einer Längsseite 2b des Rahmens 2 bzw. zur Längsseite 2b des Spinnbalkens 1 angeordnet. Eine weitere Rohrleitung 10 führt das Wärmeträgermedium aus der Wärmekammer 27b zum Kondensor 9 ab. FIG. 1 further shows a flange connection 11 for a pipeline, via which liquid plastic is conveyed to the pump 24 by an extruder arranged externally. The flange 11 is also attached to the spinning beam 1 and connected by means of pipes 12 to the pump 24 and the spinnerets. Furthermore, the spinning beam 1 has a walk-on surface, under which an insulation 13 is arranged. The modular assembly 20a according to Figure 2 essentially comprises a suspension 21, which has at least two transverse beams 21a, 21b, between which the heat chambers 27a, 27b and the openings 23a, 23b, 23c are arranged for the spin packs with the spinnerets. It can be seen that in this embodiment, the spinning beam 1 is designed for three spin packs, each with a spinneret, since each opening 23a, 23b, 23c can receive a spin pack. The spinning beam 1 can also be designed only for a spinning package, two spin packages, or for more than three spin packages. In the longitudinal direction of the spinning beam 1 so the spin packs are arranged one behind the other to produce a variable number of spinning lines. The heat chambers 27a, 27b are an integral part of the suspension 21 and connect the cross members 21a, 21b with each other, so that a self-supporting modular assembly 20a is formed within the spinner 1. In order for the heat transfer medium to circulate, the heat chambers 27a, 27b are connected to one another in the region of the cross members 21a, 21b in such a way that the spin packages are evenly heated on two further sides, the end faces. On the cross members 21a, 21b pads 22a - 22d are arranged, with which the modular assembly 20a in the frame 2 or in a framework can be suspended. On the opposite side to the heat chambers 27a, 27b, the boiler 25 is arranged lying on the cross member 21b. For this purpose, angle profiles are arranged on an end face on the cross member 21a, 21b, in which the boiler 25 is adjustably mounted in the embodiment. The boiler 25 is placed horizontally so that the openings 26 for the heating rods are accessible without further disassembly from a gangway of a scaffold. For this purpose, the boiler 25 is arranged transversely or orthogonally to a longitudinal side 2b of the frame 2 or to the longitudinal side 2b of the spinning beam 1. Another pipeline 10 leads the heat transfer medium from the heat chamber 27b to the condenser 9.
Die modulare Baugruppe 20a umfasst damit die Aufhängung 21 , die durch die zwei Querträger 21a, 21 b mit den dazwischen angeordneten Wärmekammern 27a, 27b verbunden ist. Die Wärmekammer 27a ist über eine Rohrleitung 28 mit dem Boiler 25 verbunden, der ebenfalls Bestandteil der modularen Baugruppe 20a ist. Weiterer Bestandteil der modularen Baugruppe 20a ist die Pumpe 24, die an bzw. im Bereich der Wärmekammer 27b liegend angeordnet ist und alle innerhalb der Baugruppe integrierten Spinndüsen mit extrudiertem Kunststoff versorgt, sowie die Rohrleitung 10. Die Querträger 21a, 21 b weisen weiterhin Auflagen 22a - 22d auf, an denen die modulare Baugruppe 20a in den Rahmen 2 oder in ein Gerüst einhängbar und befestigbar ist. The modular assembly 20a thus includes the suspension 21, which is connected by the two transverse beams 21a, 21b with the heat chambers 27a, 27b arranged therebetween. The heat chamber 27a is connected via a pipe 28 to the boiler 25, which is also part of the modular assembly 20a. Another component of the modular assembly 20a is the pump 24, on or in the area of Heat chamber 27b is arranged horizontally and supplies all integrated within the assembly spinnerets with extruded plastic, as well as the pipe 10. The cross member 21a, 21b further have pads 22a - 22d, in which the modular assembly 20a in the frame 2 or in a framework can be hung and fastened.
Die Pumpe 24, die über eine Welle 5 mit dem Antrieb 4 verbunden ist, wird über die Rohrleitung 12 mit flüssigem Kunststoff von einem außerhalb des Spinnbalkens 1 angeordneten Extruder versorgt. Hierzu wird über den Flanschanschluss 1 der flüssige Kunststoff zur Pumpe 24 und von dieser über weitere Rohrleitungen zu den Spinndüsen geleitet. Von Vorteil ist, dass alle Rohrleitungen, die flüssigen Kunststoff zu den Spinndüsen leiten, fallend angeordnet sind, damit ein Zurückfließen der flüssigen Schmelze zum Extruder oder zur Pumpe 24 beim Austausch von Komponenten vermieden wird. Innerhalb der Rohrleitungen für flüssigen Kunststoff, beispielsweise der Rohrleitung 12, können an einer oder mehrerer Stellen Mischer integriert sein, die den geschmolzenen Kunststoff durchmischen. The pump 24, which is connected via a shaft 5 to the drive 4, is supplied via the pipe 12 with liquid plastic from an outside of the spinning beam 1 arranged extruder. For this purpose, the liquid plastic is passed to the pump 24 via the flange connection 1 and from there via further pipelines to the spinnerets. It is advantageous that all pipelines which conduct liquid plastic to the spinnerets are arranged to fall, so that a backflow of the liquid melt to the extruder or to the pump 24 during the exchange of components is avoided. Within the pipes for liquid plastic, such as the pipe 12, mixers can be integrated at one or more points, which mix the molten plastic.
In dem Ausführungsbeispiel der Figuren 3 und 4 sind vier modulare Baugruppen 20a, 20b, 20c, 20d an einem Rahmen 2 angeordnet und bilden den Spinnbalken 1. Jede modulare Baugruppe 20a - 20d wird mit beiden Querträger 21a, 21 b in den Rahmen 2 eingehängt, wobei die Auflagen 22a - 22d auf einem Profil des Rahmens 2 aufliegen und mit diesem verbunden sind. Jede modulare Baugruppe 20a - 20d kann in diesem Ausführungsbeispiel zwei Spinnpakete mit jeweils einer Spinndüse aufnehmen, die in die Öffnungen 23a, 23b einsetzbar und mit den Abdeckungen 3a, 3b verschließbar sind. Unter den Abdeckungen 3a, 3b können die Spinnpakete durch einsetzbare Wärmeblöcke nach oben isoliert werden, die eine umlaufende Dichtung aufweisen, um innerhalb der Öffnung 23a, 23b einen Kamineffekt zu vermeiden. Die Spinnpakete sind parallel zwischen den Längsseiten 2b des Rahmens 2 angeordnet. Eine Vakuumstation 8 und ein Kondensor 9 sind für den Wärmekreislauf aller Baugruppen mit allen Boilern 25 über Rohrleitungen verbunden, wobei von jedem Boiler 25 eine Rohrleitung 28 das Wärmeträgermedium zu den Wärmekammern 27a leitet. Dabei sind die Boiler 25 über eine Rohrleitung 14 untereinander verbunden, so dass sich für jede modulare Baugruppe 20a - 20d auch bei Mehrfachanordnung der gleiche Wärmekreislauf ergibt. Über einen einzigen Flanschanschluss 11 werden alle Spinnpakete von einem externen Extruder mit flüssigem Kunststoff versorgt. Hierzu ist eine Rohrleitung 12 angeordnet, die ausgehend von dem Flanschanschluss 11 den flüssigen Kunststoff zu den Pumpen 24 leitet. Die Vorderseite des Spinnbalkens 1 , in deren Bereich die Antriebe 4 angeordnet sind, ist für das Bedienungspersonal zur Wartung der Pumpen 24 leicht zugänglich, so dass von dieser Seite auch die Heizstäbe in den Boilern 25 gewechselt werden können. Dazu sind die Boiler 25 liegend und quer bzw. orthogonal zur Längsseite 2b des Rahmens 2 angeordnet. Dadurch, dass auch die Pumpe 24 liegend und quer bzw. orthogonal zur Längsseite des Spinnbalkens 1 angeordnet ist, kann der gesamte Spinnbalken 1 aus einer Position gewartet werden. Beide Maßnahmen, nämlich die liegende Anordnung des Boilers 25 und der Pumpe 24 quer bzw. orthogonal zur Längsseite des Rahmens 2 ermöglicht eine kompaktere Bauweise des Spinnbalkens 1 , da für die Wartung beider Bauteile kein Platzbedarf zwischen den Spinnpaketen bzw. zwischen den Baugruppen erforderlich ist. Dies erfolgt ausschließlich am Bediengang des Gerüstes, der genug Platz für das Wechseln der langen Heizstäbe und der Pumpen 24 aufweist. Bezugszeichen In the exemplary embodiment of FIGS. 3 and 4, four modular assemblies 20a, 20b, 20c, 20d are arranged on a frame 2 and form the spinning beam 1. Each modular assembly 20a-20d is suspended in the frame 2 with both cross members 21a, 21b. wherein the supports 22a - 22d rest on a profile of the frame 2 and are connected thereto. Each modular subassembly 20a-20d, in this exemplary embodiment, can accommodate two spin packs each having a spinneret which can be inserted into the openings 23a, 23b and closed by the covers 3a, 3b. Under the covers 3a, 3b, the spin packs can be insulated by insertable heat blocks upwards, which have a circumferential seal to avoid a chimney effect within the opening 23a, 23b. The spin packs are arranged in parallel between the longitudinal sides 2b of the frame 2. A vacuum station 8 and a condenser 9 are connected for the heat cycle of all modules with all boilers 25 via pipes, from each boiler 25, a pipe 28, the heat transfer medium to the heat chambers 27a directs. The boilers 25 are connected to each other via a pipe 14, so that the same heat cycle results for each modular assembly 20a - 20d even with multiple arrangement. All spinning packages are supplied with liquid plastic from an external extruder via a single flange connection 11. For this purpose, a pipe 12 is arranged, which, starting from the flange connection 11, directs the liquid plastic to the pumps 24. The front side of the spinning beam 1, in the area of which the drives 4 are arranged, is easily accessible to the operating personnel for the maintenance of the pumps 24, so that the heating elements in the boilers 25 can also be changed from this side. For this purpose, the boiler 25 are arranged horizontally and transversely or orthogonal to the longitudinal side 2b of the frame 2. Due to the fact that the pump 24 is also arranged lying horizontally or orthogonally to the longitudinal side of the spinning beam 1, the entire spinning beam 1 can be maintained from one position. Both measures, namely the horizontal arrangement of the boiler 25 and the pump 24 transversely or orthogonal to the longitudinal side of the frame 2 allows a more compact design of the spinner 1, since no space requirement between the spinning packages or between the modules is required for the maintenance of both components. This takes place exclusively at the operating passage of the scaffold, which has enough space for changing the long heating rods and the pumps 24. reference numeral
