Definitions

  • the invention relates to a clapper for a braiding machine whose Bobbin top one serving as an axis of a thread bobbin sitting thereon Pipe sleeve having at its free end a head piece for securing the Seat of the bobbin on the tube sleeve is releasably held and with a Thread tensioner, the one exchangeably taken in the tubular sleeve, as Clamping element acting coil spring, which with a Spring end supported on the head piece.
  • the conversion includes, from the bobbins, the tension springs expand and by installing tension springs with such spring stiffness to replace, which causes a respective desired thread tension.
  • the head piece for Securing the bobbin a screwed to the pipe sleeve part.
  • the Part has an external thread, so that it is in an internal thread of the Pipe sleeve can be screwed.
  • the replacement of the tension springs thus requires the unscrewing of the head piece and the replacement of the Tension spring.
  • the header is then with a predetermined Screw torque back into the pipe sleeve.
  • the invention is based on the object, the assembly work for the Replacing an acting as a tensioning coil spring of To simplify the thread tensioner of a bobbin of a braiding machine and thereby also shorten.
  • the head piece can be inserted in the tubular sleeve or retractable shaft portion.
  • Pipe sleeve and shaft section are thereby designed such that they are against each other in a predetermined Plug position are fixed. These are latchable locking elements intended.
  • the assembly-consuming screwing is therefore by a simple Insertion or insertion process replaced, with latchable locking elements cause the lock in the predetermined insertion position.
  • the locking elements are designed such that the Mutual locking between tube sleeve and shank portion at any time easiest way from the outside can be solved again to the Shaft section to pull out of the tube sleeve, for example, to the Tension spring from the top closed by the shaft portion To remove tube sleeve.
  • Lockable and always releasable locking elements persist after a development of a located on the shaft portion spring tongue and an area of the wall of the wall adjacent to the spring tongue Pipe sleeve located recess into which a at the free end of the inserted deflected spring tongue existing snap stop engages as soon as the shaft portion has reached the insertion position, in which congruates the snap stop with the recess.
  • the recess is an approximately radially introduced into the tube sleeve Drilling.
  • the snap stop is one to the diameter of the bore appropriate thickening at the free end of the spring tongue.
  • the recess is a bore, it offers the advantage that in the Bore from the inside of the tube sleeve from protruding snap stop of outside is accessible. He can, for example, by means of a suitable Tool pushed back under renewed deflection of the spring tongue be, with which the shaft section again freely movable and out of the Pipe sleeve is pulled out.
  • head piece and pipe sleeve or Shank section at the initiation of insertion is not against each other can be rotated, which would make the assembly difficult again Headpiece and tube sleeve each corresponding to each other or in Activation engageable anti-rotation elements.
  • Anti-rotation elements can be designed as tongue and groove.
  • Shank portion of the head piece receives, for example, a projecting Spring, which in a recessed groove in the wall of the tube sleeve can intervene.
  • a projecting Spring which in a recessed groove in the wall of the tube sleeve can intervene.
  • tongue and groove Anti-rotation elements are present as tongue and groove Anti-rotation elements on top of each other, so correspond to each other, can the insertion or insertion movement of the shaft portion in the Tube sleeve into be completed until the snap stop on the Spring tongue snaps into its associated hole.
  • each forms a specific coil spring a header with shaft portion a preassembled replacement unit.
  • Each holding nip is advantageously an extension of the shaft portion pen protruding from it.
  • Each holding nubs has at least one radial projection, which against the each adjacent turn of the associated coil spring protrudes and thereby between the turns of the pats put on the holding Coil spring engages.
  • the coil spring is through the holding nubs, due to their Embodiment are resilient, releasably connected to the shaft portion, but still so firmly attached to them that they are in operation a braiding machine readily on the shaft portion and thus on Can support head piece.
  • the shank portion is together with the securing head piece with particularly advantageous integrated in a component.
  • the component an injection molded plastic, so that the plastic of the head piece without Another in a predetermined color code for certain properties of the associated coil spring can be colored.
  • a bobbin for a braiding machine is shown in section.
  • the Bobbin upper part 2 of the clapper 1 has an axis as sitting on it Thread bobbin 3 serving pipe sleeve 4 on.
  • Thread bobbin 3 serving pipe sleeve 4 on.
  • a head piece for securing the seat of the thread bobbin 3 on the tube sleeve.
  • 4 detachably held by a shaft portion 6 of the head piece 5 from above in the tube sleeve 4 is inserted.
  • On reaching into the tube sleeve 4 lower End of the shaft portion 6 is one end of a clamping element of a Thread tensioner acting coil spring 7, located in the tubular sleeve is located and thus supported on the head piece 5.
  • the lower end of the coil spring 7 acts on a in the pipe sleeve. 4 guided sliding pin 8.
  • the sliding pin 8 is by means of a bolt 9 with a Rocking lever 10 is connected, via the bearing 11 on the bobbin upper part. 2 is hinged pivotally.
  • a claw 12 At the free end of the rocker arm 10 is a claw 12, in the one Wire pull 13 is mounted.
  • the wire 13 is by an am Bobbin top 2 located eyelet 14 out.
  • the wire 13 carries at his free end a thread guide eye 15.
  • wire 13 with thread guide eye 15, rocker arm 10 with sliding pin 8 and coil spring 7 are elements a thread tensioner.
  • the thread tensioner holds one of the thread bobbin 3 in Direction of the indicated arrows withdrawn thread 16, during his Course through the eyes 17 and 18 for not shown Flecht gleich in the area of a Flechtscholle the braiding machine, under one predetermined thread tension.
  • the head piece 5 is about mushroom-shaped projections 19, which are visible here, because Fig. 2 a compared to Fig. 1 rotated by 90 ° view.
  • the head piece 5 with its insertable into the tube sleeve 4 shank portion 6 is an injection molded part made of plastic.
  • the shaft portion 6 has a molded spring tongue 20 on. At the free end of the spring tongue 20 is located a snap stop 21, here as a thickening 22 of the spring tongue 20 is formed.
  • a recess 23 in the form a simple hole. If the head piece 5 with its shaft portion. 6 inserted into the tube sleeve 4 from above, so first the thickening 22 at the free end of the spring tongue 20, the spring tongue 20 deflect until a Inserted position of the shaft portion is reached, in which the Snap stop 21, or the thickening 22, in the recess 23rd snaps or clicks. As a result, the head piece 5 with the tube sleeve 4th locked.
  • the head piece 5 with its shank portion 6 from the tube sleeve 4 again can be removed from the outside through the recess 23 on the Thickening 22, for example, with a suitable tool, so pressed be that the spring tongue 20 is deflected inwardly, whereby the Snap stop 21 out of engagement with the tube sleeve 4 comes.
  • anti-rotation elements which is caused by that the head piece 5 with its shank portion 6 relative to the tube sleeve 4th can not be twisted.
  • the coil spring 7 can be assembled by attaching to the holding nubs with the consisting of shaft portion 6 and head piece 5 a component form a preassemblable unit. Such units allow a change quickly accomplish the tension springs of a clapper.
