Definitions

  • the invention relates to a yarn tensioning device having an inlet guide, an outlet guide and therebetween a thread drum having an axis of rotation and a working area, in the circumferential direction a thread path between the inlet guide and the outlet guide, wherein the working area is divided into at least two sections in the axial direction, which have different properties.
  • Out DE 33 36 651 A1 is a rotating yarn brake with integrated Vorbremsung known, with a thread is guided around a thread drum.
  • the thread drum has a working area, which is divided into two sections in the axial direction. The sections are provided with V-shaped grooves and have different diameters.
  • the yarn is first fed through the smaller diameter section and then passes through a diverter into the larger diameter section. Due to the diameter differences a tension is created in the thread which causes the thread to slip against the thread drum without slipping.
  • JP 2000351528 A For example, there is shown a thread tensioner having a thread drum with a working area of the thread drum divided into sections of different diameters. With the help of a coupling individual sections can be connected to a load device. As a result, a variable voltage can be introduced into a thread.
  • the sections each have a V-shaped groove for guiding the thread.
  • Another thread tensioning device is for example off DE 43 24 412 A1 known. It serves to provide a thread, which is withdrawn from a spool arranged in a gate, with a tension which is desired for a subsequent further processing of the thread.
  • the thread drum for example, braked or at a different speed than the thread be driven. If a thread passes through the thread path, then it is in the work area on the thread drum and is braked or accelerated accordingly, so that sets the desired tension in the thread.
  • Different threads usually have different properties as well. This can cause a thread drum that works well with one type of thread to fail with another type of thread. Accordingly, you can make the thread drum interchangeable. The operator will then use a matching thread drum depending on the type of thread used.
  • a thread tensioning device is usually required for each spool position.
  • a gate can have several hundred coil positions. For example, even if changing a thread drum requires only 15 seconds, a gate that has 800 spool positions requires 200 minutes, well over three hours.
  • the invention has for its object to achieve high flexibility with little expenditure of time.
  • a first portion has a smooth contact surface and a second portion has a V-shaped groove.
  • the smooth contact surface encloses an acute angle with the axis of rotation.
  • the contact surface is thus formed in the form of a cone section. The thread path can then be guided so that individual turns of the thread do not cross each other.
  • the groove has at least one wall in which teeth and interdental spaces alternately are arranged.
  • Such an arrangement is also referred to as "Criprad”.
  • a crimping wheel has the advantage that you can achieve a good frictional engagement between the thread drum and the thread.
  • dirt can settle out, for example residues of a finish, and that filaments can be pulled out with sensitive threads or yarns.
  • the groove is formed between two plate members, wherein a plate member facing the first portion forms a boundary for the first portion toward the second portion.
  • a plate member facing the first portion forms a boundary for the first portion toward the second portion.
  • the inlet guide and / or the outlet guide are adjustable relative to the thread drum between a first position, which is associated with the first portion, and a second position, which is associated with the second portion, adjustable.
  • the adjustment can consist both in that one adjusts the inlet guide and / or the outlet guide parallel to the axis of rotation and in that one adjusts the position of the thread drum parallel to the axis of rotation. It can thus be achieved that the thread at the inlet and / or the outlet of the respective section correctly is assigned. This keeps a load of the respective thread small.
  • a Fadenleit worn is arranged with at least one movable thread guide.
  • the yarn guide can be under the tension of a spring, for example.
  • the thread guiding element can be used to change the force with which the thread wraps around the thread drum.
  • the position of the thread guiding element and the thread drum is variable relative to one another in a direction parallel to the axis of rotation. Even when passing through the yarn guide then no impermissible stresses are applied to the thread. In addition to the thread guide alone, you can also adjust the entire Fadenleit Nur relative to the thread drum, where you can adjust either the thread drum or Fadenleit worn or both here.
  • a calming device is arranged in the thread path behind the inlet guide, the position of which is adjustable relative to the thread drum in a direction parallel to the axis of rotation.
  • a reassurance makes sense to achieve a uniform application of force to the thread when circulating around the thread drum. Due to the adjustability parallel to the axis of rotation can also be achieved here that the thread can pass through the thread tensioning device in a desired direction, preferably in a plane. If the thread is passed over the tapered smooth surface, however, the inlet and the outlet of the thread parallel to the rotation axis may be slightly apart.
  • Fig. 1 shows a thread tensioning device 1 with a base 2, on which a thread drum 3 is rotatably mounted.
  • the thread drum 3 can be rotatably connected to an electric motor 4, which can also be operated as a generator.
  • an inlet guide 5 and an outlet guide 6 are arranged.
  • a thread 7 is guided through the inlet guide 5, wraps around the thread drum 3 and is then guided through the outlet guide 6.
  • a calming device 8 is arranged, which is formed by two conically shaped plates 9, 10 which lie with their smaller diameter on each other.
  • the reassurance 8 dampens vibrations in the thread 7, which could be caused by the withdrawal of the thread 7 overhead, for example, from a coil, not shown.
  • a yarn guide 11 is arranged with a movable Fadenleitelement 12 which is movable in the direction of a double arrow 13, that is substantially transverse to the direction of the yarn 7.
  • the yarn guide 12 can by a spring not shown under a certain bias can be set.
  • the thread drum has a work area 14, which has a first portion 15 and a second portion 16.
  • the first section 15 has a smooth contact surface for the thread 7. It is slightly conically inclined, i. the abutment surface includes an acute angle with a rotation axis 22 of the thread drum 3. At the end with the smaller diameter, a cover plate 17 is provided, which projects radially beyond the first portion 15. This prevents that the thread 7 can be removed via the head of the first section 15.
  • the second section 16 has a V-shaped groove 18. How out Fig. 3 can be seen, the groove 18 at least one wall 19, in which teeth 20 and tooth spaces 21 are arranged alternately.
  • the second section 16 is thus designed as a "crimping wheel" and has a relatively good frictional engagement with the thread 7 when the thread 7 is guided through the second section 16.
  • the groove 18 is formed between two plates 23, 24.
  • the first section 15 facing plate 23 has a slightly larger diameter than the first portion 15 in the region of the plate 23 so that the plate 23 forms a boundary for the first portion 15 in the direction of the second portion 16.
  • the thread 7 can not accidentally slip out of the first section 15 in the second section 16 or vice versa.
  • the thread drum 3 has on its side facing the base 2 an extension 30 with an opening 25 which can be plugged onto a shaft of the motor 4. By attaching the thread drum can be rotatably connected to the motor 4.
  • the thread drum 3 may also have more than the two illustrated sections 15, 16. In many cases, however, you will get along with two different sections.
