Description

Die Erfindung betrifft eine Spule für eine Flechtmaschine zum Flechten von Verstärkungseinlagen eines Schlauches gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a coil for a braiding machine for braiding reinforcing inserts of a hose according to the preamble of claim 1.

Derartige Spulen für Flechtmaschinen sind aus dem Stand der Technik bereits seit langem bekannt. Die einzelnen Spulen, die auf der Scheibe der Flechtmaschine angeordnet sind, bewegen sich auf kreisförmigen Sinusbahnen um einen Schlauchrohling herum, um auf dessen äußerer Oberfläche eine Verstärkungseinlage zu flechten. Hierbei wird von dem Spulenkern einer jeden Spule der Faden abgezogen. Der Spulenkern ist über eine Abziehsicherung auf einem Spulenhaltersockel des Spulenhalters gesichert, um zu verhindern, dass hierbei der Spulenkern von der Spule abgezogen wird. Bei den aus dem Stand der Technik bekannten Spulen ist die Abziehsicherung als Bajonettverschluss ausgebildet, in den Verschlusselemente des Spulenkerns eingreifen. Mit Hilfe einer solchen Abziehsicherung kann ein Abziehen des Spulenkerns von der Spule wirksam verhindert werden. Es ist jedoch festzustellen, dass der Bajonettverschluss einen komplizierten Aufbau aufweist und darüber hinaus viel Bauraum benötigt. Der von der Abziehsicherung benötigte Bauraum steht nicht für den Spulenkern zur Verfügung, so dass sich das Volumen des auf den Spulenkern aufgewickelten Fadens reduziert. Dies führte dazu, dass die Spulen häufiger gewechselt werden müssen.Such spools for braiding machines have been known for a long time from the prior art. The individual coils, which are arranged on the disc of the braiding machine, move on circular sinusoids around a tube blank to braid on the outer surface of a reinforcing insert. In this case, the thread is removed from the spool core of each spool. The bobbin is secured by a Abziehsicherung on a bobbin holder base of the bobbin holder, to prevent that in this case the bobbin is withdrawn from the spool. In the case of the coils known from the prior art, the pull-off protection is designed as a bayonet closure, in which the closure elements of the coil core engage. With the help of such Abziehsicherung peeling of the bobbin from the coil can be effectively prevented. However, it should be noted that the bayonet lock has a complicated structure and also requires a lot of space. The space required by the Abziehsicherung is not available for the bobbin, so that reduces the volume of the wound on the bobbin thread. As a result, the coils have to be changed more frequently.

Eine Spule der eingangs genannten Art ist aus der DE 483 065 bekannt. Bei der aus dieser Druckschrift bekannten Spule ist der Spulenkern zwischen dem Spulenhaltersockel des Spulenhalters und der Fadenbremse angeordnet, so dass die Fadenbremse ein Abziehen des Spulenkerns von der Spule wirksam verhindert. Zum Austausch des Spulenkerns ist es jedoch notwendig, die Fadenbremse von dem Spulenhalter zu entfernen.A coil of the type mentioned is from the DE 483 065 known. In the known from this document coil of the bobbin between the bobbin holder base of the bobbin holder and the yarn brake is arranged so that the yarn brake effectively prevents removal of the bobbin from the coil. However, to replace the spool core, it is necessary to remove the thread brake from the spool holder.

Aus der DE 842 522 ist eine Spule bekannt, bei der der Spulenkern zwischen dem Spulenhaltersockel des Spulenhalters und der Fadenbremse eingeklemmt ist. Die Fadenbremse enthält einen Kugelkopf, der in eine Aussparung des Spulenkerns eingreift. Am anderen Ende des Spulenkerns greift ein Zapfen des Spulenkerns in eine Vertiefung des Spulenhaltersockels ein, der mit einer Feder in Längsrichtung federnd gelagert ist. Durch Herunterdrücken des Spulenkerns entgegen der Federkraft kann der Spulenkern aus dem Kugelkopf der Fadenbremse gelöst werden, so dass der Spulenkern freigegeben wird und ausgetauscht werden kann.
Aus der GB 17,153 ist eine Spule bekannt, die einen Spulenkern mit einer Hohlachse aufweist. Durch die Hohlachse des Spulenkerns wird die Längsachse des Spulenhalters geführt. An der Längsachse des Spulenhalters befindet sich eine Feder, die aus der Hohlachse des Spulenkerns herausragt und durch die der Spulenkern auf dem Spulenhalter zurückgehalten wird. Eine Spule mit ähnlichem Aufbau ist aus der US 2,028,744 bekannt.
Der Erfindung liegt die Aufgabe zugrunde, eine Spule für eine Flechtmaschine zum Flechten von Verstärkungseinlagen eines Schlauches zu schaffen, bei der die Abziehsicherung einen einfachen Aufbau aufweist und wenig Bauraum benötigt. Der Erfindung liegt ferner die Aufgabe zugrunde, eine Flechtmaschine mit derartigen Spulen zu schaffen.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 und des nebengeordneten Anspruchs 5 gelöst.
Der Vorteil der Erfindung ist darin zu sehen, dass die Fadenbremse einen einfachen Aufbau hat und dennoch die Abziehsicherung in die Fadenbremse integriert ist. Ein weiterer Vorteil des Ausführungsbeispiels ist darin zu sehen, dass die Nase, die an dem Hebel befestigt ist, beim Aufschieben des Spulenkerns auf den Spulenhalter automatisch in die Nut des Spulenkerns eingreift. Somit ist es ausgeschlossen, dass die Abziehsicherung versehentlich nicht arretiert wird.From the DE 842 522 a coil is known in which the bobbin is clamped between the bobbin holder base of the bobbin holder and the thread brake. The thread brake includes a ball head which engages in a recess of the spool core. At the other end of the spool core engages a pin of the spool core in a recess of the bobbin holder base, which is spring-mounted with a spring in the longitudinal direction. By pushing down the spool core against the spring force, the spool core can be released from the ball head of the thread brake, so that the spool core is released and can be replaced.
From the GB 17,153 a coil is known which has a coil core with a hollow axis. Through the hollow axis of the spool core, the longitudinal axis of the bobbin holder is guided. On the longitudinal axis of the bobbin holder is a spring which protrudes from the hollow axis of the bobbin and is retained by the bobbin on the bobbin holder. A coil of similar construction is from the US 2,028,744 known.
The invention has for its object to provide a coil for a braiding machine for braiding reinforcing inserts of a hose, in which the Abziehsicherung has a simple structure and requires little space. The invention is also based on the object to provide a braiding machine with such coils.
The object is solved by the characterizing features of claim 1 and the independent claim 5.
The advantage of the invention is the fact that the yarn brake has a simple structure and yet the Abziehsicherung is integrated into the yarn brake. Another advantage of the embodiment is the fact that the nose, which is attached to the lever, automatically engages when pushing the bobbin on the bobbin holder in the groove of the spool core. Thus, it is impossible that the Abziehsicherung is accidentally locked.

Gemäß einer Weiterbildung der Erfindung nach Anspruch 2 hat das Zahnrad einen größeren Durchmesser als der Spulenkern und ist koaxial an dem Ende des Spulenkerns befestigt, das dem Spulenhaltersockel zugewandt ist, wobei die Nut durch einen Absatz gebildet wird, der auf der vom Spulenhaltersockel abgewandten Seite des Zahnrades zwischen dem Zahnrad und dem Spulenkern entsteht. Der Vorteil dieser Weiterbildung ist darin zu sehen, dass Spulenkern und Zahnrad aus einem einzigen Bauteil bestehen und somit kostengünstig, z.B. im Spritzgussverfahren, aus Kunststoff hergestellt werden können.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 3 enthält der Spulenkern zwei voneinander beabstandet Bordränder, wobei zur Ausbildung zwischen dem Bordrand, der dem Spulenhaltersockel am nächsten liegt und dem Zahnrad ein Abstand verbleibt. Der Vorteil dieser Weiterbildung ist darin zu sehen, dass ein Spulenkern mit Bordrändern ein größeres Fadenvolumen aufnehmen kann als ein Spulenkern ohne Bordränder. Das Spulenvolumen kann somit nochmals erhöht werden. Ein weiterer Vorteil ist darin zu sehen, dass ein Spulenkern mit Bordrändern eine höhere Ausfallsicherheit aufweist. So kann z.B. nicht der Fall auftreten, dass sich die Nase des Hebels in dem aufgewickelten Faden verhakt, da zwischen der Nase des Hebels und dem Faden ein Bordrand liegt.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 4 ist die Nase derart bemessen, dass sie auch in der Freigabeposition in die Nut des Spulenkerns eingreift. Der Vorteil dieser Weiterbildung ist darin zu sehen, dass die Nase zu jedem Zeitpunkt in die Nut eingreift und somit zu jedem Zeitpunkt sichergestellt ist, dass der Spulenkern nicht von dem Spulenhalter abgezogen werden kann.According to one embodiment of the invention according to claim 2, the gear has a larger diameter than the spool core and is coaxially fixed to the end of the bobbin, which faces the bobbin holder base, wherein the groove is formed by a shoulder which faces away from the bobbin holder base of the Gear between the gear and the coil core is formed. The advantage of this development is the fact that coil core and gear consist of a single component and thus cost, for example by injection molding, can be made of plastic.
According to one embodiment of the invention according to claim 3, the spool core contains two spaced-apart edges of the board, wherein for training between the edge of the board, which is closest to the bobbin holder base and the gear remains a distance. The advantage of this development is the fact that a bobbin with margins can accommodate a larger volume of thread than a bobbin without margins. The coil volume can thus be increased again. Another advantage is the fact that a coil core with margins has a higher reliability. For example, it can not be the case that the nose of the lever hooked in the wound thread, as between the nose of the lever and the thread is a Bordrand.
According to one embodiment of the invention according to claim 4, the nose is dimensioned such that it engages in the release position in the groove of the spool core. The advantage of this development is the fact that the nose engages in the groove at any time and thus ensures at any time that the bobbin can not be removed from the bobbin holder.

Fig. 1 zeigt in stark schematischer Darstellung eine Flechtmaschine 2 zum Flechten von Verstärkungseinlagen eines Schlauches. Die Flechtmaschine 2 weist eine Scheibe 4 auf, auf der mehrere Spulen 6 angeordnet sind. Die Spulen 6 bewegen sich auf kreisförmigen Sinusbahnen 8, 10 um das Zentrum 12 der Scheibe 4 herum. Durch das Zentrum 12 der Scheibe 4 wird ein (in der Fig. 1 nicht gezeigter) Schlauchrohling geführt, der während der Bewegung der Spulen 6 auf den Sinusbahnen 8, 10 Fäden von den Spulen abzieht. Durch die kreisförmige Bewegung der Spulen 6 um den Schlauchrohling herum wird auf den Schlauchrohling eine Verstärkungseinlage aufgeflochten. Hierbei bewegen sich die Spulen 6 auf einer Sinusbahn 8, 10 im Uhrzeigersinn und auf der anderen Sinusbahn 8, 10 gegen den Uhrzeigersinn. Das Verfahren zum Flechten einer Verstärkungseinlage eines Schlauches mit Hilfe der gezeigten Flechtmaschine ist an sich aus dem Stand der Technik bekannt und soll daher nicht näher erläutert werden.An embodiment and further advantages of the invention will be explained in connection with the following figures. It shows:

Fig. 1 shows a highly schematic representation of a braiding machine 2 for braiding reinforcing inserts of a hose. The braiding machine 2 has a disc 4, on which a plurality of coils 6 are arranged. The coils 6 move on circular sinusoids 8, 10 around the center 12 of the disc 4 around. Through the center 12 of the disc 4 is a (in the Fig. 1 not shown) tube blank, which deducts threads from the coils during the movement of the coils 6 on the sinusoids 8, 10. Due to the circular movement of the coils 6 around the tube blank, a reinforcing insert is braided onto the tube blank. In this case, the coils 6 move on a sinusoidal track 8, 10 in the clockwise direction and on the other sinusoidal track 8, 10 in the counterclockwise direction. The method for braiding a reinforcing insert of a Hose with the aid of the braiding machine shown is known per se from the prior art and will therefore not be explained in detail.

Fig. 2a zeigt eine Spule 6 und Fig. 2b einen Spulenträger 16 im Detail. Der Spulenträger weist einen Spulenhalter 16 und einen Spulenhaltersockel 14 (siehe Fig. 2b) auf. Auf den Spulenhalter 16 wird zur Vervollständigung der Spule 6 ein Spulenkern 18 drehbar gelagert aufgeschoben (siehe Fig. 2a). An dem Spulenhaltersockel 14 befindet sich ein beweglich gelagerter Hebel 20, der mit einem Umlenkarm 22 in Wirkverbindung steht. Parallel zu dem Spulenhalter 16 verläuft ein Arm 24 mit einer Öse 26 und einem Fadenauge 28. Der auf den Spulenkern 18 aufgewickelte Faden wird zunächst durch die Öse 26 und davon ausgehend über den Haken des Umlenkarmes 22 durch das Fadenauge 28 geführt. Vom Fadenauge 28 wird der Faden schließlich auf den (in den Figuren nicht gezeigten) Schlauchrohling geführt. Fig. 2a shows a coil 6 and Fig. 2b a bobbin 16 in detail. The bobbin has a bobbin holder 16 and a bobbin holder base 14 (see FIG Fig. 2b ) on. On the spool holder 16, a spool core 18 is rotatably mounted to complete the coil 6 (see Fig. 2a ). On the bobbin holder base 14 is a movably mounted lever 20, which is in operative connection with a deflection arm 22. Parallel to the bobbin holder 16 extends an arm 24 with an eyelet 26 and a thread eye 28. The wound on the bobbin 18 thread is first passed through the eyelet 26 and starting over the hooks of the Umlenkarmes 22 through the thread eye 28. From the thread eye 28, the thread is finally guided to the (not shown in the figures) tube blank.

Der Hebel 20 greift in einen Zwischenraum zwischen zwei Zähne des Zahnrades 30 ein. Wenn der Faden von dem Spulenkern 18 abgezogen wird, so spannt er sich zunächst. Durch die Fadenspannung wird auf den Umlenkarm 22 eine Kraft ausgeübt, die über das Gelenk 32 auf den Hebel 20 übertragen wird. Bei einer bestimmten Fadenspannung wird der Hebel 20 entgegen der Rückstellkraft einer Feder aus dem Zwischenraum zwischen zwei Zähnen des Zahnrades 30 herausgezogen, so dass das Zahnrad 30 dann für eine Drehung freigegeben ist. Der Hebel 20 befindet sich dann in der Freigabeposition für das Zahnrad. Aufgrund der Freigabe des Zahnrades 30 dreht sich der Spulenkern 18 und der Faden wird von dem Spulenkern 18 abgezogen. Dadurch sinkt die Fadenspannung, so dass der Hebel 20 durch die Rückstellkraft der Rückstellfeder wieder in die Ausgangsposition überführt wird und in die Zähne des Zahnrades 30 eingreift. Der Hebel 20 geht erst dann wieder in die Freigabeposition über, wenn sich genug Fadenspannung aufgebaut hat. Durch das Zusammenspiel von Hebel 20 und Zahnrad 30 wird in dem Spulenträger also eine an sich bekannte Fadenbremse aufgebaut, die die Fadenspannung des Fadens annähernd konstant hält.The lever 20 engages in a space between two teeth of the gear 30 a. When the thread is withdrawn from the spool core 18, it first tensions. By the thread tension a force is exerted on the deflection arm 22, which is transmitted via the joint 32 to the lever 20. At a certain yarn tension, the lever 20 is pulled against the restoring force of a spring from the space between two teeth of the gear 30, so that the gear 30 is then released for rotation. The lever 20 is then in the release position for the gear. Due to the release of the gear 30, the spool core 18 rotates and the yarn is withdrawn from the spool core 18. As a result, the thread tension decreases, so that the lever 20 is transferred by the restoring force of the return spring back to the starting position and engages the teeth of the gear 30. The lever 20 does not return to the release position until enough thread tension has built up. Due to the interplay of lever 20 and gear 30 so a known thread brake is constructed in the bobbin, which keeps the thread tension of the yarn approximately constant.

Am oberen Ende des Hebels 20 weist der Hebel 20 eine Nase 34 auf, die sich ausgehend vom Hebel 20 nach radial innen erstreckt. Die Nase 20 greift oberhalb des Zahnrades 30 (also auf der von dem Spulenhaltersockel 14 abgewandten Seite des Zahnrades 30) in eine Nut 36 (siehe auch Fig. 3) des Spulenkerns 18 ein. Die Nase 34 ist derart dimensioniert, dass sie sowohl in der Ausgangsposition des Hebels als auch in der Freigabeposition des Hebels in die Nut 36 des Spulenkerns 18 eingereift. Durch den Eingriff der Nase 34 in die Nut 36 ist eine Abziehsicherung realisiert, die das Abziehen des Spulenkerns 18 von dem Spulenhalter 16 verhindert. Wenn der Spulenkern 18 von dem Spulenhalter 16 abgezogen werden soll, um einen neuen Spulenkern auf den Spulenhalter 16 schieben zu können, so wird der Hebel 20 über die Freigabeposition so weit hinausgezogen, dass die Nase 34 aus der Nut 36 vollständig herausgezogen ist und den Spulenkern 18 freigibt.At the upper end of the lever 20, the lever 20 has a nose 34, which extends from the lever 20 radially inward. The nose 20 engages above the gear 30 (ie on the side facing away from the coil holder base 14 side of the gear 30) in a groove 36 (see also Fig. 3 ) of the spool core 18 a. The nose 34 is dimensioned such that it engages in the groove 36 of the spool core 18 both in the initial position of the lever and in the release position of the lever. The engagement of the nose 34 in the groove 36 a Abziehsicherung is realized, which prevents the removal of the spool core 18 of the coil holder 16. When the spool core 18 is to be withdrawn from the bobbin holder 16 in order to push a new bobbin on the bobbin holder 16, the lever 20 is pulled over the release position so far that the nose 34 is completely pulled out of the groove 36 and the bobbin 18 releases.

Fig. 3 zeigt einen Spulenkern 18 in detaillierter Darstellung. An einem Ende des Spulenkerns 18 ist das Zahnrad 30 koaxial befestigt. Der Durchmesser D des Zahnrades 30 ist größer als der Durchmesser d des Spulenkerns 18. Die Nut 36 am Ende des Spulenkerns 18 wird durch einen Absatz 38 gebildet, der zwischen dem Zahnrad 30 und dem Spulenkern 18 entsteht. Der Spulenkern 18 enthält neben dem Zahnrad 30 zusätzlich zwei voneinander beabstandete Bordränder 40, 42, zwischen denen der Faden auf den Spulenkern 18 aufgewickelt wird. Der Spulenkern 18 mit dem Zahnrad 30 und den Bordrändern 40, 42 wird bevorzugt einteilig im Spritzgussverfahren aus Kunststoff hergestellt. Der Spulenkern 18 wird derartig auf den Spulenhalter 16 der Spule 6 (siehe Fig. 2b) aufgeschoben, dass das Zahnrad 30 dem Spulenhalter 16 zugewandt ist und die Nase 34 des Hebels 20 oberhalb des Zahnrades 30 in die Nut 34 bzw. in die Stufe 38 eingreift. Fig. 3 shows a spool core 18 in detail. At one end of the spool core 18, the gear 30 is coaxially mounted. The diameter D of the gear 30 is greater than the diameter d of the spool core 18. The groove 36 at the end of the spool core 18 is formed by a shoulder 38 which is formed between the gear 30 and the spool core 18. The spool core 18 contains in addition to the gear 30 in addition to two spaced-apart rim edges 40, 42, between which the thread is wound onto the spool core 18. The spool core 18 with the gear 30 and the rim edges 40, 42 is preferably made in one piece by injection molding of plastic. The bobbin 18 is so on the bobbin holder 16 of the coil 6 (see Fig. 2b ), that the gear 30 faces the bobbin holder 16 and engages the nose 34 of the lever 20 above the gear 30 in the groove 34 and in the stage 38.

Fig. 4 zeigt einen Querschnitt durch den Spulenhalter 18 entlang der Linie IV/IV. Das Zahnrad 30 weist einzelne Zähne 44 auf, wobei in den Zwischenraum zwischen zwei Zähnen 44 jeweils der Hebel 20 (siehe Figuren 2a und 2b) eingreift, wenn er sich in der Ausgangsposition befindet. Hierbei greift dann die Nase 34 in die Nut 36 bzw. in den Absatz 38 ein, so wie es auch durch die Nase 34 dargestellt ist. Fig. 4 shows a cross section through the coil holder 18 along the line IV / IV. The gear 30 has individual teeth 44, wherein in the space between two teeth 44 each of the lever 20 (see FIGS. 2a and 2 B ) engages when it is in the home position.
