Definitions

  • the invention relates to a thread store according to the preamble of claim 1.
  • Such a thread store is known from EP 0 534 263.
  • the thread store disclosed there has an essentially cylindrical storage drum, on the circumferential surface of which thread turns can be deposited.
  • the thread supply stored there can be withdrawn overhead through a central draw-off eye.
  • a thread brake is provided there so that the thread can be drawn off with a specific thread tension.
  • a brake strip made of a flexible material is glued into a truncated cone-shaped holding member.
  • the inside of the holding element is spring-loaded on a trigger sliding surface of the drum end region.
  • the thread is clamped between the take-off sliding surface and the braking surface of the brake strip in this thread storage device.
  • the funnel-shaped braking surface rests on a curved trigger sliding surface of the front drum area.
  • the contact surfaces between the braking surface and the trigger sliding surface are minimal. Because of the only punctiform thread clamping, the brake strip is only loaded linearly there. In the case of a thread store constructed similarly to the described embodiment, this has the consequence that the thread imprints the brake strip over the course of time on a circumferential washboard-shaped wave structure. With a brake strip destroyed in this way, it is no longer possible to pull off the thread evenly. As a result of the cushioning acting only at the front and in the coaxial direction to the drum axis, the brake ring performs an overall movement when the thread is drawn off, which occurs during a complementary radial cushioning, as is the case with the memory on the market, degenerates into a wobble movement.
  • a funnel-shaped holding element according to US Pat. No. 4,068,807, which has a rubber disc which serves as a braking element, performs a purely axial evasive movement.
  • a funnel-shaped holding member is provided in the support area on a curved drum face with a metal coating which, due to the only axially acting forces, pinches the thread at a point.
  • a large number of thread brakes are known from WO 91/14032, which are essentially actively modulated. There the thread is mostly angled towards the brake strip and pulled under the latter. From Fig. 29 there plate-like brakes in the form of a flat truncated cone jacket are already known, which pinch the thread at a point.
  • a thread store is known from AT 328 993, in which the end face of a measuring drum is designed as a conical surface which interacts with the end face of a clamping plate.
  • the clamping plate is provided with an insert made of elastic material in the area interacting with the conical surface.
  • the clamping plate is rotatably mounted on a sleeve which is displaceable in a sleeve. When the thread tension changes, the clamping plate can lift off the end face, in order to modulate the brake pressure acting on the thread, similar to US Pat. No. 4,068,807.
  • the invention is therefore based on the object of developing a generic thread store in such a way that the thread take-off is improved.
  • the contact surface between the braking surface and the trigger sliding surface has been considerably enlarged.
  • the contact surface now has the shape of the surface of a truncated cone.
  • the opening angle of the funnel-shaped brake strip corresponds to the angle of the truncated cone-shaped trigger sliding surface.
  • the thread is pulled between the flat support of the brake strip and the trigger sliding surface.
  • the thread is preferably drawn off in such a way that it leaves the thread brake in the tangential direction to the take-off sliding surface. This is preferably achieved in that the thread take-off eye is located in the region of the imaginary cone tip of the take-off sliding surface. This ensures that the contact force of the brake strip on the storage drum is independent of the thread tension. This results in a constant thread tension.
  • a preferred further development of a thread store of the generic type to reduce an evasive movement of the holding member provides an intermediate layer of elastic material between the holding member and the brake strip.
  • the brake strip itself can consist of highly flexible material due to the intermediate layer of elastic material.
  • the intermediate layer preferably consists of a foam body. If the holding surface of the holding member runs parallel to the brake strip, the intermediate layer has a substantially rectangular cross section. The radial latitude the foam body can be slightly less than the radial width of the brake strip.
  • the thickness of the intermediate layer is preferably smaller than the width of the brake strip, but larger than the maximum thread thickness that can be stored.
  • the elastic intermediate layer between the holding member and the brake strip has the advantage that the brake strip can dodge locally in the direction of the holding member when the thread is drawn off. The evasive movement can thus take place in the direction of the surface normal of the brake strip.
  • an evasive movement of thread brake elements to a braking surface or counter-braking surface has already been proposed.
  • the braking elements are formed by plates.
  • a continuous, consistently smooth braking surface is an advantage.
  • the holding member is cushioned in the axial direction.
  • the brake strip is preferably formed from a thin, internally smooth metal strip, the thickness of which is preferably less than 0.1 mm.
  • the brake strip preferably does not itself have to contribute to the dimensional stability of the brake arrangement, it can be designed to be highly flexible, preferably from a very thin metal foil.
  • the axial cushioning of the holding member can be adjusted to adjust the contact force of the brake ring on the drum end area.
  • the spring travel of the intermediate layer is preferably less than a twentieth, preferably about a fiftieth, of the circumference of the storage drum.
  • the trigger sliding surface which is assigned to the drum end region, also forms a surface section of a cone here. This surface section can be smaller or larger in its radial extent than the width of the braking surface.
  • the thread store preferably has a stationary drum, on which by means of a motor-driven Winding arm the thread turns are deposited.
  • the maximum storable thread thickness is much smaller than the width of the trigger slide surface or the width of the brake strip. Together with the high flexibility of the brake strip and its flat cushioning relative to the holding member, a local deflection (deflection) of the brake strip in the direction of its surface normal can therefore be achieved.
  • the surface section of the brake strip which does not deviate because of the thread intermediate layer, remains essentially at rest, as does the holding member.
  • a version of the invention provides that a truncated cone-shaped braking surface rests flat on the frustoconical end region of the drum, which is supported by a ring section encompassing the storage drum at the drum end.
  • the frustoconical brake strip protrudes freely into the gap between the rings.
  • An annular spring element preferably acts on the support ring.
  • the annular spring element preferably has an internal damping.
  • An elastic foam has proven to be advantageous as the material. With this spring element, the support ring is attached to a mounting ring.
  • the brake assembly consisting of foam body and brake strip together with ring section and fastening ring is clipped into a holding ring with the fastening ring.
  • the retaining ring is fastened to an arm of the storage drum housing and can be displaced in the axial direction together with the retaining ring.
  • the displaceability in the axial direction is preferably carried out by a Piston cylinder unit, which is driven pneumatically. If necessary, a spring can serve as the restoring force. It is also conceivable to use an electromagnet for the axial displacement of the retaining ring.
  • the axial displacement of the retaining ring is accompanied by a change in the preload with which the brake strip rests on the braking surface.
  • the variation of the pretension is preferably carried out in time with the weft insertion of a weaving machine or the like. With this timing, the braking effect can be actively modulated during thread take-off.
  • the braking is increased by compressing the foam ring at the end of the weft insertion.
  • the damping of the spring element has the advantage that, even at high clock rates, no resonance frequencies are excited in the brake arrangement, which can lead to a dirty thread take-off.
  • the thread store 1 has a motor housing 22 which has a thread insertion opening 23 at its lower end, which leads into a hollow shaft of the motor.
  • the motor housing 22 is fastened to a carrier 25.
  • a thread depositing arm 24 rotating around the storage drum 2 is driven by the motor and deposits thread turns 3 on the surface of the storage drum 2.
  • Windows 27 are provided in the storage drum 2, through which organs reach in a known manner to promote the thread turns 3 in the take-off direction.
  • the thread 5 is withdrawn overhead from the storage drum 2, namely through a thread withdrawal eye 4 which is arranged axially to the storage drum 2.
  • the storage drum 2 forms a trigger sliding surface 6 at its trigger end region 2 ′.
  • the trigger sliding surface 6 is formed by a truncated cone, through which the cylindrical surface of the storage drum 2 merges into the end face of the storage drum 2. This trigger sliding surface 6 thus forms a surface section of a cone.
  • the width of the conical surface is preferably about 1 cm.
  • the thread 5 slides in a circumferential manner on this take-off sliding surface 6 when the thread is drawn off.
  • a braking surface 8 is provided which is supported on the pull-off sliding surface 6 in a spring-loaded manner.
  • the thread is thus drawn between two spring-loaded surfaces, namely on the one hand the trigger sliding surface 6 and on the other hand the braking surface 8.
  • the surfaces 6 and 8 lie flat on one another.
  • the braking surface 8 is formed by the inner surface of a braking strip 9.
  • the brake strip 9 consists of an approximately 0.1 mm thick or thinner sheet which is bent to form a truncated cone. The seam of the sheet metal strip runs obliquely to the radial, so that a regular, continuous thread pull tension is achieved. However, it is also provided that the brake strip can, for example, be pressed or deep-drawn from a single piece.
  • the brake strip 9 is highly flexible. It can be deformed with little force.
  • the brake strip 9 is fastened to a holding surface 11 of the holding element 10 by means of a foam body 12, which also has the shape of a truncated cone.
  • the foam body 12 is glued to the outer surface 9 'of the brake strip opposite the braking surface 8.
  • the foam body 12 forms thus an elastic intermediate layer between the holding member 10 and the brake strip 9.
  • the cross section of the foam body 12 is rectangular and the holding surface 11 is also conical and arranged parallel to the brake strip 9.
  • the foam body 12 can be compressed almost by its entire thickness by being acted upon.
  • the thickness of the foam body 12 is smaller than the width of the brake strip 9, but larger than the largest possible storeable thread thickness, so that the spring travel is sufficient for a local evasive movement of the brake strip when the thread is pulled through.
  • the size ratio of the thickness of the intermediate layer and the storage drum circumference is particularly conducive to this.
  • the spring travel of the intermediate layer is less than one twentieth of the circumference of the storage drum, and in the exemplary embodiment it is approximately one fiftieth.
  • the thread thicknesses are predominantly much smaller (at least one order of magnitude) than the intermediate layer thickness.
  • the foam body 12 has a radial extension of approximately 12 mm.
  • the radial extent of the brake strip 9 is approximately 15 mm, so that almost the entire outer surface of the brake strip 9 is glued to the foam body 12.
  • the other side of the foam body 12 is glued to the holding surface 11 of the holding member.
  • the holding surface 11 is formed by a section 10 'of the holding member, which also has a truncated cone shape.
  • One yourself Webs 21, which leave windows 16 open between them, are integrally formed in the withdrawal direction and adjoining the section 10 '.
  • the webs 21 extend radially inwards and axially on the take-off side and open into a holder for a thread take-off bushing 14, which is arranged centrally.
  • the thread take-off bushing 14 has a pull-off eye character and protrudes into a funnel-shaped opening 17 of a fastening part 15, with which the holding member 10 is fastened to a carrier 20 fixed to the housing.
  • the carrier 20 is, however, additionally adjustable in the axial direction compared to the carrier 25.
  • a total of eight compression springs 13 are provided which are aligned axially to the drum axis and which are arranged circumferentially around the cylindrical thread take-off sleeve 14.
  • these springs can be more or less tensioned, as a result of which the contact force of the braking surface 8 on the trigger sliding surface 6 can be adjusted.
  • the fastening part 15 is shifted in the direction x.
  • the fastening part 15 has an external thread section 18 which surrounds the funnel-shaped opening and which can be screwed to the carrier 20 via a nut 19.
  • the partial region 26 of the brake strip 9, which receives the thread 5 between itself and the take-off sliding surface 6, can form a formation 26.
  • the thread is shown greatly enlarged in strength.
  • This formation 26 carries out a circular orbital movement around the axis of the thread storage device when the thread is drawn off, while the remaining area of the brake strip 9 remains at rest on the take-off sliding surface 6 in flat contact.
  • the foam body 12 is compressed at the corresponding points.
  • the evasive movement of the brake strip 9 takes place in the direction of its surface normal, namely in the direction of the parallel holding surface 11. It is considered advantageous that in this embodiment the holding member 10 is essentially not moved when the thread is drawn off.

  • the thread is pulled between the trigger sliding surface 6 and the braking surface 8. Both surfaces are made of metal and are essentially smooth. A braking effect is achieved in that the brake strip 8 is pressed onto the trigger sliding surface 6 due to the resilient action by the spring elements 31. When the thread 5 is pulled through this thread brake, there is an evasive movement due to a slight compression of the plastic part 12.
  • the thread take-off eye 4 is arranged coaxially to the axis of the storage drum 2.
  • the axial distance of the thread take-off eye 4 from the end face of the storage drum 2 is chosen so that the thread 5 leaves the take-off sliding surface 6 parallel to the surface tangent.
