Description

Die Erfindung bezieht sich auf eine Staubschutzanlage an einer Wickelmaschine, insbesondere an einer Schär- oder Zettelmaschine, mit der Fäden von Spulen insbesondere von einem Spulengatter abziehbar und als Fadenschar auf einen Wickelbaum aufwickelbar sind, mit einer innerhalb eines Gebäudes parallel zum Wickelbaum vertikal angeordneten, die gesamte Frontseite hinter der Maschine gegen Zugluft abschirmenden Abschirmwand, die mit einer einen Maschinenbedienplatz gegen Zugluft abschirmenden Schutzscheibe versehen ist, und mit einer zugluftseitig vor der Abschirmwand und oberhalb der Wickelmaschine angeordneten Luftabsaugeinrichtung.The invention relates to a dust protection system on a winding machine, in particular on a warping or warping machine, with which the threads of bobbins can be pulled off, in particular, from a creel and wound onto a winding tree as a thread family, with a vertically arranged inside a building parallel to the winding tree, the Entire front behind the machine shielding against drafts, which is provided with a protective screen shielding a machine operator station against drafts, and with an air suction device arranged in front of the shield and above the winding machine on the draft side.

Eine Staubschutzanlage mit den vorgenannten Merkmalen ist aus der DE 38 43 608 A1 bekannt. Die Abschirmwand der bekannten Anlage reicht von der Gebäudedecke bis zum Boden, auf dem die Anlage aufgebaut ist. Der Maschinenbedienplatz ist zwischen dieser Abschirmwand und der Wickelmaschine angeordnet. Da die Bedienungsperson infolgedessen von dem durch die Wickelmaschine erzeugten Luftstrom voll getroffen würde, ist vertikal über der Achse des Wickelbaums die mit der Abschirmwand verbundene Windschutzscheibe angeordnet. Die oberhalb der Wickelmaschine angeordnete Luftabsaugeinrichtung besteht aus einem Absaugtrichter, der über ein Rohrleitungssystem an eine Luftfördereinrichtung angeschlossen ist, mit der abgesaugte Luft über ein Filter zurück in den Raum gefördert wird. Der durch diese Staubschutzanlage erzielte Schutzeffekt ist verbesserungsfähig. Zum einen kann Zugluft und damit Staub seitlich von der Schutzsscheibe und von der Maschine bis zu der Bedienungsperson vordringen. Das ist wegen der immer höheren Wickelgeschwindigkeiten und der damit verbundenen Zugluftentwicklung nicht mehr annehmbar, zumal auch der Staubanfall durch größere Zugluftgeschwindigkeiten vergrößert wird. Um bei der bekannten Staubschutzanlage durch die Luftabsaugeinrichtung eine wirksame Absaugung im Fadenauflaufbereich der Wickelmaschine zu erreichen, muß der Absaugtrichter nahe der Fadenauflaufstelle angeordnet werden und dort hohe Luftgeschwindigkeiten bewirken. Das kann dazu führen, daß die Fadenschar in Unordnung gerät, beispielsweise dadurch, daß Fäden aus dem kurz vor der Auflaufstelle der Fäden auf den Wickelbaum vorhandenen Fadenleitriet herausgesaugt werden. Diese Gefahr ist insbesondere dann gegeben, wenn Betriebszustände und damit Fadenspannungen wechseln, beispielsweise beim Stillsetzen der Wickelmaschine. Als wesentliche weitere nachteilige Wirkung der bekannten Wickelanlage ist festzuhalten, daß die Staubabsaugung durch die bekannte Luftabsaugeinrichtung nur einen geringen Teil des insgesamt anfallenden Staubes beseitigen kann. Der weitaus größere Rest verteilt sich in der Umgebung der Anlage, z.B. durch benutzte Blaseinrichtungen zur Sauberhaltung staubkritischer Stellen z.B. am Spulengatter und/oder durch Luftbewegungen innerhalb des Gebäudes.A dust protection system with the aforementioned features is known from DE 38 43 608 A1. The shielding wall of the known system extends from the building ceiling to the floor on which the system is built. The machine operator station is arranged between this shielding wall and the winding machine. Since the operator would consequently be hit completely by the air flow generated by the winding machine, the windshield connected to the shielding wall is arranged vertically above the axis of the winding tree. The air suction device arranged above the winding machine consists of a suction funnel which is connected to an air conveying device via a pipe system is extracted with the extracted air back into the room through a filter. The protective effect achieved by this dust protection system can be improved. On the one hand, drafts and thus dust can penetrate laterally from the protective screen and from the machine to the operator. This is no longer acceptable due to the ever increasing winding speeds and the associated draft development, especially since the dust accumulation is also increased by higher draft speeds. In order to achieve effective suction in the thread run-up area of the winding machine in the known dust protection system by means of the air suction device, the suction funnel must be arranged near the thread run-up point and cause high air velocities there. This can lead to the thread coulter becoming disordered, for example in that threads are sucked out of the thread guide rod present shortly before the point of contact of the threads on the winding tree. This danger is particularly present when operating conditions and thus thread tension change, for example when the winding machine is stopped. As a further significant disadvantageous effect of the known winding system, it should be noted that the dust extraction by the known air extraction device can only remove a small part of the total dust. The much larger remainder is distributed in the vicinity of the system, for example by using blowing devices to keep dust-critical points clean, for example on the creel and / or by air movements within the building.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Staubschutzanlage mit den eingangs genannten Merkmalen so zu verbessern, daß mit der oberhalb der Wickelmaschine angeordneten Luftabsaugeinrichtung die gesamte Umgebung der Wickelanlage staubfrei gehalten werden kann.The invention is therefore based on the object of improving a dust protection system with the features mentioned at the outset so that the entire environment of the winding system can be kept dust-free with the air suction device arranged above the winding machine.

Diese Aufgabe wird dadurch gelöst, daß über die gesamte von der Wickelmaschine, deren Fadenschar und den Spulen eingenommene Länge innerhalb des Gebäudes angeordnete, den von der Fadenschar erzeugten Luftstrom zur Luftabsaugeinrichtung hin kanalisierende Seiten- und Deckenwände vorhanden sind.This object is achieved in that arranged over the entire length of the winding machine, its thread sheet and the bobbins inside the building, the air flow generated by the thread sheet to the air suction device channeling side and ceiling walls are present.

Durch diese Maßnahmen wird erreicht, daß eine einzige Luftabsaugeinrichtung in die Lage versetzt wird, den gesamten beim Aufwickeln anfallenden Staubanfall mit einfachen Mitteln zu beseitigen, ohne daß dabei der Wickelvorgang nachteilig beeinflußt werden könnte oder die Bedienungsperson auch nur im geringsten der Zugluft oder dem Staub ausgesetzt wäre. Dafür ist wesentlich, daß der von der Fadneschar erzeugte Luftstrom ausgenutzt wird, welcher mit Hilfe der Seiten- und Deckenwände der Staubschutzanlage zur Luftabsaugeinrichtung hin kanalisiert wird. Der apparative Aufwand der Staubschutzanlage bleibt also klein, verglichen mit allgemein bekannten Lösungen, bei denen eine Vielzahl von Luftabsaugeinrichtungen an denjenigen Stellen eingesetzt wird, an denen besonders viel Staub anfällt. Vor allem wird aber auch Staubanfall dort erfaßt, wo eine Einzelabsaugeinrichtung aus Wirtschaftlichkeitsgründen nicht eingesetzt werden kann. Durch die Kanalbildung mit Hilfe der Seiten- und Dekkenwände wird aber auch erreicht, daß innerhalb des Gebäudes vorhandene Luftbewegungen nicht zu einer Verteilung des Staubs im Gebäude führen können.These measures ensure that a single air suction device is able to remove all of the dust accumulated during winding up with simple means, without the winding process being adversely affected or being exposed to the drafts or the dust in the slightest way would. It is essential that the air flow generated by the Fadneschar is used, which is channeled with the help of the side and ceiling walls of the dust protection system to the air suction device. The outlay in terms of apparatus for the dust protection system thus remains small compared to generally known solutions in which a large number of air extraction devices are used in those places where a particularly large amount of dust is produced. Above all, however, dust accumulation is detected where a single suction device cannot be used for reasons of economy. The channeling with the help of the side and ceiling walls also ensures that existing air movements within the building cannot lead to a distribution of the dust in the building.

Wenn die Seiten- und Deckenwände dicht an die Außenkanten der Abschirmwand anschließen, kann die Absaugwirkung verbessert werden, indem Nebenluft vermieden wird.If the side and ceiling walls are close to the outer edges of the shielding wall, the suction effect can be improved by avoiding secondary air.

Eine bauliche Vereinfachung wird erreicht, indem die Schutzscheibe in die Abschirmwand fluchtend eingebaut ist, die den Maschinenbedienplatz von der Wickelmaschine trennt und daß die Abschirmwand bedarfsweise ein Steuerpult aufweist. Die Schutzscheibe kann infolgedessen vorgefertigter Bestandteil der Abschirmwand sein. Außerdem ist jedoch von Bedeutung, daß der Maschinenbedienplatz hermetisch gegen die Wickelmaschine abgedichtet wird. Zugleich ist die Abschirmwand dadurch ein Sicherheitselement, weil sie ein unbeabsichtigtes Berühren der in Betrieb befindlichen Wickelmaschine verhindert. Dadurch wird ein Eingreifen in den Wikkelprozeß jedoch nicht verhindert, wenn außerhalb der abschirmenden Wände ein Steuerpult vorhanden ist, das zweckmäßigerweise an der Abschirmwand vorgesehen ist.A structural simplification is achieved in that the protective screen is installed flush in the shielding wall, which separates the machine operator station from the winding machine and that the shielding wall has a control panel if necessary. As a result, the protective pane can be a prefabricated component of the shielding wall. It is also important, however, that the machine operator station is hermetically sealed against the winding machine. At the same time, the shielding wall is a safety element because it prevents accidental contact with the winding machine that is in operation. Intervention in the winding process is not prevented, however, if a control panel is present outside the shielding walls, which control panel is expediently provided on the shielding wall.

Um die direkte manuelle Einwirkung auf die Wickelmaschine zu ermöglichen, ist die Anlage so ausgebildet, daß die Abschirmwand aus der Abschirmstellung in eine in die direkte Bedienung der Wickelmaschine vom Bedienplatz aus ermöglichende Stellung beweglich ist. Diese Beweglichkeit wird dadurch erreicht, daß zur Bewegung der in ihrer Ebene seitlich geführten Abschirmwand eine steuerbare maschinelle Hubvorrichtung vorhanden ist.In order to enable direct manual action on the winding machine, the system is designed in such a way that the shielding wall can be moved from the shielding position into a position which enables direct operation of the winding machine from the operator station. This mobility is achieved in that a controllable mechanical lifting device is provided for moving the shielding wall which is guided laterally in its plane.

Um die Leistung der Luftabsaugeinrichtung so gering wie möglich zu halten, ist die von den Seiten- und Deckenwänden spulenseitig gebildete Luftzutrittsöffnung wandfrei.In order to keep the performance of the air extraction device as low as possible, the air inlet opening formed by the side and ceiling walls on the coil side is wall-free.

Weil es erforderlich ist, daß eine Bedienungsperson Zugang zu der Fadenschar und/oder zu den Spulen hat, beispielsweise um eine Fadenverknotung im Falle eines Fadenbruchs vorzunehmen, oder um volle Spulen aufzustecken, ist die Anlage so ausgebildet, daß die Seitenwände mit Zutrittstüren versehen sind und/oder einen Spulenwagen neben dem Spulengatter zu verschieben gestattenden Abstand aufweisen.Because it is necessary for an operator to have access to the thread sheet and / or to the bobbins, for example to make a thread knot in the event of a thread break, or to attach full bobbins, the system is designed so that the side walls are provided with access doors and / or have a coil carriage next to the creel to be displaceable distance.

Eine vorteilhafte Ausgestaltung der Anlage liegt vor, wenn die Deckenwand mit einer der Wickelmaschine benachbarten Absaugöffnung versehen ist, an die die außerhalb des von den Seiten- und Deckenwänden gebildeten Ansaugkanals gebildete Luftabsaugeinrichtung angeschlossen ist. In diesem Fall ist die gesamte Luftabsaugeinrichtung außerhalb der die Anlage umkleidenden Wände angeordnet, so daß der Platzbedarf entsprechend geringer ist. Andererseits ist die Zugänglichkeit entsprechend besser. Die Luftabsaugeinrichtung kann unabhängig von der Gestaltung der Kanalisierung des Luftstroms ausgebildet werden.An advantageous embodiment of the system is provided when the ceiling wall is provided with a suction opening adjacent to the winding machine, to which the air suction device formed outside the suction channel formed by the side and ceiling walls is connected. In this case, the entire air extraction device is arranged outside the walls surrounding the system, so that the space requirement is correspondingly less. On the other hand, accessibility is correspondingly better. The air suction device can be designed independently of the design of the ducting of the air flow.

Vorteilhaft ist es, daß die Seiten- und/oder Deckenwände vom Spulengatter zur Wickelmaschine den benachbarten Fäden der Fadenschar etwa parallel ist. Dadurch wird die Führung des Luftstroms an die räumlichen Gegebenheiten der Anlage angepaßt. Es werden die Wirkungen der Luftabsaugeinrichtung beeinträchtigende Toträume vermieden und die Luftabsaugeinrichtung benötigt eine entsprechend geringere Leistung. In diesem Sinne kann es vorteilhaft sein, daß die Seiten- und/oder Deckenwände mit Lufteintrittsdüsen versehen sind. Diese Luftdüsen sind entweder passiv, dienen also der Ansaugung von Seitenluft unter Wirkung der Luftabsaugeinrichtung, oder sie sind aktiv, indem Luft eingeblasen wird.It is advantageous that the side and / or top walls from the creel to the winding machine are approximately parallel to the adjacent threads of the thread family. This adjusts the flow of air to the spatial conditions of the system. Dead spaces impairing the effects of the air suction device are avoided and the air suction device requires a correspondingly lower output. In this sense, it can be advantageous that the side and / or ceiling walls are provided with air inlet nozzles. These air nozzles are either passive, that is, they serve to draw in side air under the action of the air extraction device, or they are active by blowing in air.

Die in den Fig.1,2 dargestellte Wickelanlage besteht im wesentlichen aus einer Wickelmaschine 10 mit einem maschinell angetriebenen Wickelbaum 15, der die Fäden 11 als Fadenschar 14 von Spulen 12 eines Spulengatters 32 abzieht und aufwickelt. Dabei verläuft die Fadenschar durch ein Fadenleitriet 37 zur geordneten Zuführung der Fäden 11. Von diesem Leitriet 37 verlaufen die Fäden um eine Führungswalze 38 zur Auflaufstelle 39, wo eine Anpreßwalze 40 wirkt, um den Wickel 41 zu komprimieren.The winding system shown in FIGS. 1, 2 essentially consists of a winding machine 10 with a mechanically driven winding tree 15, which pulls the threads 11 as a group of threads 14 from bobbins 12 of a creel 32 and winds them up. The thread family runs through a thread guide reed 37 for the orderly feeding of the threads 11. From this guide reed 37, the threads run around a guide roller 38 to the run-up point 39, where a pressure roller 40 acts to compress the winding 41.

Beim Wickeln der Fäden fällt Staub an. Beispielsweise sind die Spulen 12 staubig, die Fäden 11 reiben sich an Umlenk- und Bremsstellen des Spulengatters 32 und sie werden auch im Bereich der Wickelmaschine 10 beansprucht, nämlich am Fadenleitriet 37, an der Führungswalze 38 und beim Aufwickeln selbst durch die Anpreßwalze 40. Sämtliche mit dem Wickelprozeß verbundenen Bewegungsabläufe der Anlage führen zu Luftbewegungen, welche ihrerseits den Staub verwirbeln. Infolgedessen ist eine Staubschutzanlage vorhanden, die eine unkontrollierte Ausbreitung des Staubs verhindert. An der Frontseite 17 der Maschine ist eine Abschirmwand 19 vorhanden, die sich gemäß Fig.2 über die gesamte Breite der Wikkelmaschine 10 und darüber hinaus erstreckt. Die Abschirmwand 19 trennt einen Maschinenbedienplatz 20 von der Wickelanlage, so daß die Bedienungsperson 42 vollständig gegen Zugluft 18 geschützt ist. Die Abschirmwand 19 hat eine Schutzscheibe 21, durch die die Bedienungsperson 42 den Wikkelprozeß beobachten kann. Ein manueller Zugriff ist der Bedienungsperson 42 verwehrt, wenn die Abschirmwand 19 die mit ausgezogenen Strichen dargestellte Stellung einnimmt. Es ist jedoch ein Steuerpult 43 vorhanden, mit dessen Hilfe die Bedienungsperson 42 auf den Wickelprozeß Einfluß nehmen kann. Die Bedienungsperson 42 gewinnt dadurch manuellen Zugang zur Wickelmaschine 10, daß die Abschirmwand 19 aus dem Bewegungsbereich der Bedienungsperson 42 entfernt wird. Das wird beispielsweise durch eine in der Ebene der Wand 19 erfolgende Hubbewegung erreicht, mit der die Abschirmwand 19 vertikal hochgehoben wird und in die Stellung 27 gelangt. Das Anheben erfolgt mit der Hubvorrichtung 28, die beispielsweise aus einer motorischen Aufwickeleinrichtung für ein an der Abschirmwand 19 angreifendes Seil besteht. Die Hubvorrichtung 28 ist selbst über eine Befestigungseinrichtung 44 an einer Decke 50 des Gebäudes 16 befestigt. Für eine seitliche Führung der Wand 19 beim Hochheben sorgen beispielsweise U-förmige Führungsleisten 45.Dust accumulates when the threads are wound. For example, the bobbins 12 are dusty, the threads 11 rub against deflection and braking points of the creel 32 and they are also stressed in the area of the winding machine 10, namely on the thread guide 37, on the guide roller 38 and when winding up even by the pressure roller 40. All of them Movements of the system associated with the winding process lead to air movements, which in turn swirl the dust. As a result, there is a dust protection system that prevents the dust from spreading in an uncontrolled manner. On the front side 17 of the machine there is a shielding wall 19 which, according to FIG. 2, extends over the entire width of the winding machine 10 and beyond. The shielding wall 19 separates a machine operator station 20 from the winding system, so that the operator 42 is completely protected against drafts 18. The shielding wall 19 has one Protective pane 21 through which the operator 42 can observe the winding process. Manual access is denied to the operator 42 when the shielding wall 19 assumes the position shown in solid lines. However, there is a control panel 43 by means of which the operator 42 can influence the winding process. The operator 42 gains manual access to the winding machine 10 by removing the shield 19 from the range of motion of the operator 42. This is achieved, for example, by a lifting movement taking place in the plane of the wall 19, with which the shielding wall 19 is lifted vertically and reaches position 27. The lifting takes place with the lifting device 28, which consists, for example, of a motorized winding device for a rope acting on the shielding wall 19. The lifting device 28 is itself fastened to a ceiling 50 of the building 16 via a fastening device 44. U-shaped guide strips 45, for example, provide lateral guidance of the wall 19 when raised.

Über die gesamte Länge L der Wickelanlage erstrecken sich Seitenwände 24 und eine Deckenwand 25, die an dem der Wickelmaschine 10 abgewendeten Ende des Spulengatters 32 eine Luftzutrittsöffnung 29 bilden, die wandfrei ist, so daß der Zutritt von Luft 46 ungehindert ist. Die Seitenwände 24 haben einen ausreichenden Abstand A zum Spulengatter 32, so daß sich in dem dadurch gebildeten Zwischenraum 47 die Bedienungsperson 42 bewegen kann, beispielsweise um volle Spulen 12 aufzustecken. Der Abstand A ist jedenfalls so groß, daß auch ein Spulenwagen 31 verwendet werden kann, mit dem volle Spulen zum Spulengatter 32 transportiert oder in Abspulstellung gebracht werden. Um den Zugang zum Raum 47 zwischen den Seitenwänden 24 und dem Spulengatter 32 zu erleichtern, sind in den Seitenwänden 24 Zutrittstüren 30 vorhanden, beispielsweise auf Höhe des Spulengatters 23 oder auf Höhe der Fadenschar 14.Over the entire length L of the winding system extend side walls 24 and a top wall 25, which form an air access opening 29 at the end of the bobbin 32 facing away from the winding machine 10, which is wall-free, so that the entry of air 46 is unhindered. The side walls 24 are at a sufficient distance A from the creel 32 so that the operator 42 can move in the space 47 formed thereby, for example in order to attach full coils 12. In any case, the distance A is so large that a bobbin carriage 31 can also be used, with which full bobbins are transported to the creel 32 or are brought into the unwinding position. In order to facilitate access to the space 47 between the side walls 24 and the creel 32, access doors 30 are provided in the side walls 24, for example at the level of the creel 23 or at the level of the thread sheet 14.

Die Seitenwände 24 laufen den benachbarten Fäden 11w der Fadenschar zwischen dem Spulengatter 32 und der Wickelmaschine 10 etwa parallel, so daß sich dort eine Verringerung des Abstands der Seitenwände 24 vom Spulengatter 32 zur Wickelmaschine 10 ergibt, sofern diese kürzer als das Spulengatter 32 breit ist. Jedenfalls wird dadurch erreicht, daß die Kanalisierung der in den Raum zwischen die Wände 24, 25 einströmenden Luft 46 begünstigt wird. Der Raum zwischen den Wänden 24,25 wird so gering wie möglich gehalten. Abschirmwandseitig weisen die Wände 24 U-förmige Führungsleisten 45 für die Abschirmwand 19 auf. Auch die Deckenwand 25 ist zwischen dem Spulengatter 32 und der Wickelmaschine 10 dem Verlauf der Fadenschar 14 angepaßt, um den Kanalisierungsraum im Querschnitt so klein wie möglich zu halten.The side walls 24 run approximately parallel to the adjacent threads 11w of the thread sheet between the creel 32 and the winding machine 10, so that there is a reduction of the distance between the side walls 24 from the creel 32 to the winding machine 10, provided that it is shorter than the creel 32 wide. In any case, it is achieved that the channeling of the air 46 flowing into the space between the walls 24, 25 is favored. The space between the walls 24, 25 is kept as small as possible. On the shielding wall side, the walls 24 have U-shaped guide strips 45 for the shielding wall 19. The top wall 25 between the creel 32 and the winding machine 10 is adapted to the course of the thread sheet 14 in order to keep the cross-section of the sewage system as small as possible.

In den Fig.1,2 ist dargestellt, daß in den Seitenwänden 24 Lufteintrittsdüsen 34 vorhanden sind, was durch die Pfeile 48 symbolisiert wird. Dementsprechend kann Luft zutreten, die infolge der Düsenwirkung des Luftstroms 23 zwischen den Wänden 24,25 mitgerissen wird, oder es kann ein Gebläse dazu verwendet werden, um die Seitenluft einzublasen. Derartige Lufteintrittsdüsen 34 können auch in der Deckenwand 25 vorhanden sein.FIGS. 1, 2 show that air inlet nozzles 34 are present in the side walls 24, which is symbolized by the arrows 48. Accordingly, air can enter that is entrained between walls 24, 25 due to the jet effect of air flow 23, or a blower can be used to blow in the side air. Such air inlet nozzles 34 can also be present in the top wall 25.

Im Bereich der Wickelmaschine 10 ist in der Deckenwand 25 eine Absaugöffnung 33 vorhanden, die sich darstellungsgemäß über die gesamte Breite der Wickelmaschine erstreckt. Ihre exakte Bemessung ist an die tatsächlichen räumlichen Gegebenheiten anzupassen, wie auch an die Wirkung des Luftstroms 23 und an etwaige innerhalb des Luftkanals vorhandene Luftleiteinrichtungen. Die Luftaustritts- bzw. Absaugöffnung 33 führt in eine aus Luftleitungen 35 gebildete Absaugeinrichtung 22, in der beispielsweise ein Staubfilter 36 und ein Gebläse 49 angeordnet ist. Mit Hilfe des Gebläses 49 wird die Luft durch den Filter 36 gesaugt und gereinigt zurück in das Gebäude 16 gefördert.In the area of the winding machine 10 there is a suction opening 33 in the ceiling wall 25 which, as shown, extends over the entire width of the winding machine. Their exact dimensioning is to be adapted to the actual spatial conditions, as well as to the effect of the air flow 23 and to any air guiding devices present within the air duct. The air outlet or suction opening 33 leads into a suction device 22 formed from air lines 35, in which, for example, a dust filter 36 and a blower 49 are arranged. With the aid of the blower 49, the air is sucked through the filter 36 and conveyed back cleaned into the building 16.

Beim Betrieb der Wickelanlage wird durch die Fadenschar 14 innerhalb der Wände 24,25 bzw. des Bodens 51 ein Luftstrom 23 erzeugt, der beträchtlich ist. Er ist umso stärker, je höher die Wickelgeschwindigkeit ist. Diese vergrößert sich im Laufe der Entwicklung der Wickelmaschinen jedoch ständig, um eine hohe Produktion beim Wickeln zu erreichen. Dieser Luftstrom 23 wird dazu benutzt, die anfallenden Staubteilchen in Richtung auf die Absaugöffnung 33 zu fördern, was dadurch ermöglicht wird, daß die besagten Wände 24,25 einen Ansaugkanal bilden. Infolgedessen kommt die Luftabsaugeinrichtung 22 mit vergleichsweise geringer Leistung aus und vermag doch den gesamten Staubanfall der vergleichsweise großen Wickelanlage zu bewältigen.When the winding system is in operation, the thread sheet 14 generates an air flow 23 within the walls 24, 25 or the floor 51 which is considerable. The higher the winding speed, the stronger it is. However, this increases continuously in the course of the development of the winding machines in order to achieve high production during winding. This air flow 23 is used to convey the dust particles in the direction of the suction opening 33, which is made possible by the fact that said walls 24, 25 form an intake duct. As a result, the air suction device 22 manages with a comparatively low output and is nevertheless able to cope with the entire amount of dust generated by the comparatively large winding system.
