Definitions

  • the invention relates to a winding unit of a cheese-producing textile machine according to the preamble of claim 1.
  • Fadenabzugsbevant device is for example in the DE 44 18 312 A1 described.
  • This known Fadenabzugsbevanter has a guide surface for the thread, which has the shape of a truncated cone, wherein the large diameter faces the spinning cop.
  • the truncated cone shell is penetrated by a truncated pyramid shell so that the edges of the truncated pyramid shell pierce the truncated cone shell and thereby form notches.
  • these devices Compared with other known thread take-off accelerators, these devices have the advantage that the thread balloon that forms when the thread is pulled off the head of the spinning cop, not destroyed or suppressed, but only shaped.
  • each of these Abspulinsvoriquesen consists of three telescoped tubular thread guide elements. That is, a lower, lowered over the Spinnkops guide element is guided vertically adjustable on a central yarn guide tube, which in turn is fixed by a clamping means to another tubular member which is stationary on a mounting plate of the winding unit.
  • the first tubular thread guide element which is cone-shaped in the region of its lower edge, is defined during the rewinding operation by means of an associated drive so lowered over the spinning cop, that the cone is always positioned in the region of the so-called Kopskegels the spinning cop.
  • the middle thread guide tube which is fixed by a clamping device on the upper tubular member, remains during Umspulvorganges in its tuned, for example, at the beginning of a new batch to the respective length of the spinning cops to be machined installation position and has on the input side a bottleneck.
  • a multiple thread balloon is divided.
  • the DE 42 21 559 A1 relates to a winding unit with a comparable Abspullosesvorraum.
  • This known Abspulosvorraum has a defined height adjustable, lowered over the Spinnkops, first thread guide element on which a likewise height-adjustable mounted thread guide bell is supported.
  • the thread guide bell is guided on a slide bar between two stops, by which the maximum adjustment of the terminal is specified and has, viewed in the direction of yarn travel, on the output side a bottleneck.
  • the length of a thread balloon which, as explained above, adjusts in a spinning cop in the thread withdrawal head, limited by the position of the bottleneck of the thread guide.
  • the thread guide elements Since the bottlenecks of the above-described thread guiding elements are constantly in contact with the running thread during the rewinding process due to the rotating yarn balloon, these areas are exposed to high wear. That is, the thread guide elements must be constantly checked for wear, especially in the area of their bottlenecks and replaced if necessary, the thread guide elements.
  • Winding machines are known in which in each case a special, pneumatically acted thread receiving device is installed in the field of winding units.
  • the thread takeup device is arranged in front of the unwinding position of the winding unit and has a lowerable via a spinning cop, acted upon with compressed air bell.
  • the bell is in turn connected to an adapter to which a vacuum-loadable gripper tube can be docked.
  • a ring-shaped balloon crusher is attached to the bell in the region of a slot open to the unwinding position by means of bolts, so that both the spinning cop and the thread taken up by the spinning cop can be easily transferred into the unwinding position of the winding unit.
  • annular balloon rings are known, inter alia, in connection with twisting machines, which assisted in the production of Zwwinspulen the unwinding of the original thread of so-called disc coils.
  • the diameter of this annular, set on a ring rail of the twisting machine, for example in the DE 37 34 467 A1 described balloon rings is well above the diameter of the disc coils. Since these balloon rings are exposed during operation by the thread of a considerable load, the balloon ring on a replaceable inner ring, which is designed as a wearing part. This means, if necessary, the inner rings of the balloon rings can be replaced without the balloon rings must be carefully unscrewed from the ring rail of the twisting machine before.
  • the invention has the object to improve such winding units to the effect that on the one hand high winding speeds can be realized, but on the other hand wear parts are easily and inexpensively replaceable.
  • the inventive design of the winding unit has the particular advantage that not only the possibility is given by the use of a thread guide device with a replaceable thread guide insert to operate the winding unit with high winding speed, but that, if necessary, there is the possibility that the strongest during the winding operation claimed component of this yarn guide device to renew easily. That is, with a corresponding wear of the thread guide insert this can be exchanged for a corresponding new component.
  • the thread guide insert is fixed by means of a magnetic holder non-positively and releasably connected to the thread guide device.
  • a magnetic holder which, as described in claim 3, preferably ferromagnetic projections and arranged in receiving bores permanent magnets, allows a quick change of the thread guide insert, without the use of a tool is necessary.
  • the thread guide insert is in a preferred embodiment at least partially made of a wear-resistant material, preferably made of a technical ceramic material. That is, the thread guide insert consists of a base body, for example, the cost-effective in printing or. Injection molding method is made of a metal or a plastic and are arranged on the ferromagnetic projections for the magnet holder and a wear-resistant thread inlet part. This yarn inlet part, which, as already mentioned above, preferably made of a technical ceramic material is made, it is insoluble, for example, by gluing, attached to the base body. Such a constructed thread guide insert can not only be produced relatively inexpensively but is also characterized by a long service life.
  • the thread guide insert has a clear width corresponding to the clear width of the tubular thread guide device.
  • the clear width of a loop-like opening of the thread guide insert is below the clear width of the thread guide device.
  • the eye-like opening of the thread guide insert for example, as described in claim 11, have a round cross section, or, as set forth in claim 13, have a polygonal cross-section.
  • the yarn inlet region of the yarn guide insert is preferably funnel-shaped, wherein the inlet surface of the yarn guide insert, viewed in longitudinal section, either rectilinear (Anspr. 8) runs or convexly curved (Anspr. 9) is formed.
  • the thread on the one hand at the beginning of the winding process can be easily blown up or sucked through the eye-like opening and that on the other hand, the rotating thread during the winding process, when it rotates in the opening, is not damaged.
  • the convexly curved inlet surface of the yarn guide insert additionally has notches. These notches initiate vibrations on the revolving thread, which also have a positive effect on the thread balloon.
  • FIG. 1 is a side view schematically a cross-wound producing textile machine, in the embodiment, a so-called cross-winding machine 1, shown.
  • spooling machines 1 have between their (not shown) Endgestellen a plurality of similar work or winding units 2.
  • these winding units 2 as is known and therefore not explained in detail, which are produced on a (not shown) ring spinning machine, only relatively little yarn material Aus doden spinning cops 9 rewound to large-volume cheeses 11.
  • the finished cheeses 11 are then transferred by means of an automatically operating service unit, such as a cheese changer, on a machine-spooled cross-bobbin transport device 21 and transported to a machine end side (not shown) Spulenverladestation or the like.
  • an automatically operating service unit such as a cheese changer
  • Such spoolers 1 have either, as in Fig. 1 indicated, a logistics device in the form of a bobbin and tube transport system 3 on or in the area of numerous jobs 2 each a work-station own coil magazine, preferably a so-called round magazine is arranged.

As indicated, the supplied spinning cops 9 are thereby initially positioned and rewound in a unwinding position 10, which is located in the region of the transverse transport sections 6 at the winding stations 2.
  • the individual winding units 2 have for this purpose, as is known and therefore only indicated, on various thread treatment and thread handling devices that not only ensure that the spinning cops 9 too bulky Reverse spools 11 can be rewound, but also ensure that the thread during the rewinding monitored and detected thread defects can be cleaned.
  • the winding device 24 which has a coil frame 18 which is movably mounted about a pivot axis 19, a coil drive means 26 and a Fadenchangier noticed 28.
  • the cross-wound bobbin 11 during the winding process for example, with its surface on a single-motor actuated drive drum 26 and is driven by this frictional engagement.
  • Fadenchangier driven 28 which has a finger thread guide 29 in the present embodiment.
  • Fadenchangier styles 28 are known and, for example in the DE 198 58 548 A1 described in detail.
  • such winding units 2 generally also each have a thread connecting device 13, preferably a pneumatically operated splicing device, a suction tube 12 which can be subjected to negative pressure and a gripper tube 25 which can also be pressurized with negative pressure.
