Definitions

  • the invention relates to a coil for a braiding machine for braiding reinforcing inserts of a hose according to the preamble of claim 1.
  • 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.
  • the thread is removed from the spool core of each spool.
  • the bobbin is secured by a Abziehêt on a bobbin holder base of the bobbin holder, to prevent that in this case the bobbin is withdrawn from the spool.
  • the pull-off protection is designed as a bayonet closure, in which the closure elements of the coil core engage.
  • a coil of the type mentioned is from the DE 483 065 known.
  • 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.
  • 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.
  • the invention has for its object to provide a coil for a braiding machine for braiding reinforcing inserts of a hose, in which the Abzieh rejoin 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 Abziehsch 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 Abziehsch is accidentally locked.
  • 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 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.
  • the nose of the lever hooked in the wound thread, as between the nose of the lever and the thread is a Bordrand.
  • 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. 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.
  • 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.
  • the lever 20 engages in a space between two teeth of the gear 30 a.
  • the thread When the thread is withdrawn from the spool core 18, it first tensions.
  • a force is exerted on the deflection arm 22, which is transmitted via the joint 32 to the lever 20.
  • 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.
  • 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 Abzieh rejoin is realized, which prevents the removal of the spool core 18 of the coil holder 16.
  • Fig. 3 shows a spool core 18 in detail.
  • 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 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.
  • the nose 34 engages in the groove 36 and in the paragraph 38, as it is also represented by the nose 34.
