Definitions

  • the invention relates to a thread holder and a rapier weaving machine with thread holder.
  • Thread holders so-called bolt clamps
  • one holding member is firmly connected to the other holding member.
  • a holding member is movably arranged on the other holding member, the one holding member being biased against the other holding member by means of a spring and the holding force being determined by the spring force, or the holding members being movable with respect to one another in the longitudinal direction.
  • These thread holders have the disadvantages that the clamping gap is changed in cross-section and width either against the force of the spring, which means e.g. a thread is relatively heavily stressed or is not possible due to the arrangement of the holding members, because the thread is damaged during insertion and is not provided.
  • the object of the invention is to improve a thread holder in such a way that the clamping gap can be set automatically as a function of the thread thickness.
  • the advantage of the invention is essentially to be seen in the possibility of changing the clamping gap.
  • the thread holder essentially consists of a first holding member 1, a second holding member 2, a retaining member 3, a sleeve 4, a support member 5, a screw 6 and an actuating lever 7.
  • the first holding member 1 is an elongated body with a first section 10 which is formed at one end of the body and a second section 11 which is tapered towards the other end of the body.
  • a U-shaped groove 12 is formed which extends in the longitudinal direction of the body.
  • a groove-shaped recess 13 is formed with a round base, the cross section of which increases starting from the free end of the second section 11.
  • the first holding member 1 has a bore 14 for the actuating lever 7, two holes 15 for fastening the Thread holder and a stop member 16 to prevent pulling a thread in the longitudinal direction of the thread holder.
  • the stop area for the thread is determined with the stop element 16, starting from the free end of the second section 11 to the holding element 16.
  • the second holding member 2 is an elongated needle with a bent section at one end, which forms an entry aid for the thread.
  • the needle 2 has a circular cross section and an outside diameter that is smaller than the width of the groove.
  • a pin 21 is provided on the needle.
  • the sleeve 4 has a through hole 22, the cross section of which is adapted to the pin.
  • the retaining element is a leaf spring 3, which has a through bore 23 with a countersink and a through hole 24.
  • the actuating lever 7 has a pivot pin 25 which determines the pivot axis of the actuating lever 7 and is pivotably arranged on the body 1.
  • the actuating lever is designed as a two-armed lever, a pin 26 being attached to one lever arm and a tab 27 being integrally formed on the other lever arm.
  • a recess 28 is formed, which is directed transversely to the needle axis and receives the pin 26.
  • Fig. 2 shows the thread holder in the assembled state.
  • Two support members 5 are arranged in the groove 12.
  • the needle 2 is arranged in the groove 12 and lies on the one hand on the support members 5 and on the other hand on an edge 31, so that between the needle 2 and the surface of the recess 13 in the first section 10 of the body 1 there is a wedge-shaped gap 32 which has a curved cross-sectional shape.
  • the needle 2 is loosely mounted with the pin 21 in the leaf spring 3.
  • the leaf spring 3 rests on the section 10 and is held by means of the screw 6.
  • the support members 5 have a through hole 33 to fix the support members 5 in the groove 12. As can be seen from FIG.
  • the needle 2 is arranged on the one hand at the point 35 and on the other hand on the support point 36, so that the needle 2 can be rotated about the pin 21.
  • This has the particular advantage that when a thread is drawn in, the needle 2 can assume the best holding position.
  • Further essential advantages of the thread holder are that the gap 32 is present in the holding area of the thread between the surface of the recess 13 and the outer surface of the needle 2 and there is no contact between the body and the needle and that the width of the gap 32 is adjustable, to adjust the clamping gap 32 to the thread thickness. For this purpose, only the number or thickness of the support members 5 must be reduced or increased.
  • the thread holder shown in FIG. 5 has essentially the same basic structure as the thread holder described above and comprises a first holding member 41, a second holding member 42, a return spring 43, two support members 45, a screw 46 and the operating lever 7, not shown.
  • the first holding member 41 is an elongated body with a first section 48 and a second section 11.
  • first section 48 there is an essentially U-shaped recess 49 which extends in the longitudinal direction of the body 41.
  • two recesses 50 are provided in the groove 49 in order to receive the support body 51.
  • two lugs 56 are formed to guide the needle 42 during the cleaning of the thread holder.
  • the second holding member is an elongated needle 42 with a bent section at one end, which forms the entry aid for the thread, and with a support body 51 at the other end.
  • the needle 42 is arranged in the recess 13, the support body 51 being movably received in the recesses 50 and the needle 42 resting on the edge 31.
  • the leaf spring 43 is fastened to the section 48 by means of the screw 46.
  • the leaf spring 43 has a portion 53 against which the needle 42 abuts to limit the upward movement of the needle 42.
  • the needle 42 is freely movable within the recess and can assume the best holding position with different thread thicknesses, or in other words, the thread holder adjusts itself.
  • the gap 32 is set analogously to the embodiment according to FIG. 2.
  • the support members 45 have an outline which corresponds to the groove 49.
  • Figure 6 shows another embodiment of a support body, e.g. a universal joint 57.
  • the thread holder shown in FIGS. 7 to 10 contains a lower part 70, a first holding member 71, a second holding member 72, a retaining member 73, three support members 75, a bearing part 76 and an actuating lever 77.
  • the lower part 70 is an elongated body with a shoulder 81 on which the actuating lever 77 is pivotably arranged and with two bearing points 82, 83 for the second holding member 72.
  • the first holding member 71 is an elongated body with a rectangular cross section, which has a sloping end face 85 and a groove 86 with a semicircular cross section, which extends in the longitudinal direction of the body.
  • a stop member 87 is fastened to the body in order to prevent the thread from being pulled through in the longitudinal direction of the body and to determine the holding area for the thread.
  • the retaining member 73 is a leaf spring which is connected by means of screws 88, 89 at one end to the first holding member 71 and at the other end to the bearing part 76.
  • a spring bar can be used instead of the leaf spring.
  • a holding member e.g. Leaf spring, spring bar or the like.
  • Thread breaks can thus be largely avoided.
  • the bearing part 76 is a cuboid body which has a section 90 on the underside for resting on the lower part 70 and a groove 91 for receiving the needle 72 and on the top a recess 92 for receiving the leaf spring 73, the groove 91 and the Recess 92 are arranged parallel to each other.
  • the support members 75 have an outline which corresponds to the recess 92 and a small thickness e.g. up to 0.5 mm.
  • the needle 72 is mounted on the lower part 70 and the body 71 is fastened to the lower part 70 via the leaf spring 73 such that the body 71 rests on the needle 72 at one end 95 on the needle 72 and a wedge-shaped gap 96 is formed .
  • the arrangement is designed such that there is no contact between the body 71 and the needle 72 in the holding area delimiting by the stop element 87.
  • the width of the gap can be changed by reducing or increasing the number or thickness of the support members 75.
  • the bearing points 82, 83 are designed as support bearings, so that the needle 72 is movable in the plane formed by the bearing surface.
  • the needle is e.g. U-shaped holding member 97 is provided.
  • the advantage of this arrangement is in particular that the needle can take the best holding position with different thread thicknesses.
  • the first holding member 71 can be mounted and the second holding member 72 can be fixed.
  • the needle 72 is floatingly supported in the lower part 70.
  • an elongated trough 99 is formed in the lower part 70, in which the needle can move in the longitudinal direction.
  • the embodiment shown in FIG. 11 can be selected to facilitate the adjustment of the gap 96.
  • an adjusting screw 98 is used to move the leaf spring 73, which is firmly connected to a block 100, and consequently to adjust the gap 96.
  • the thread holder consists of a tubular body 101 with an extremely acute-angled end face 102, a needle 103 with a bent section 104 at one end and a ball 105 at the other end, a holding member 106 for the needle 103 and a screw 107.
  • a hemispherical recess is formed in the holding part 106, which are designed such that the ball 105 is loosely supported when the holding part 106 is fastened to the body 101 by means of the screw 107.
  • the needle 103 is freely movable within the tubular body 101.
  • a cylindrical chamber 110 which surrounds the needle 103 and a bore 111 is provided, which can be connected to a compressed air source (not shown).
  • the thread holder contains two holding members 1, 2, which form a gap 32 with a round cross-sectional shape and increasing width.
  • the holding members 1, 2 are each mounted on the other holding member at at least one bearing point 36, which is designed as a support point. With this arrangement it is advantageously achieved that the mounted holding member can assume the best holding position.
  • the thread holder is particularly suitable for a rapier gripper of a rapier weaving machine.
