Definitions

  • the invention relates to a thread guide element for a finger thread guide according to the preamble of claim 1.
  • Such thread guide elements are fundamentally known in connection with finger thread guides which change a thread running on the surface of a cross-wound bobbin.
  • finger thread guides are described with fixed to their body thread guide elements.
  • Finger thread guides are known in which the base body consists of a magnesium die-cast part. At the free end of the magnesium body are connected via flexural elastic rods, preferably carbon fiber rods, ceramic thread guide elements. That is, in corresponding holes of the magnesium body are fixed by means of adhesive carbon fiber rods on which, preferably also by an adhesive bond, each designed as a ceramic sleeve thread guide element is attached.
  • flexural elastic rods preferably carbon fiber rods
  • ceramic thread guide elements are not subject to any significant wear even with aggressive yarn, there is always the risk that the thread guide elements, for example, as a result of bending moments, never the high-frequency laying of a thread can be completely ruled out, easily break off or that the ceramic flakes off the carbon fiber rods.
  • Known finger thread guides also have the disadvantage that the adhesive bonds in the region of the carbon fiber rods form mechanical weak points, which can neither be reliably avoided, nor can be subsequently eliminated reasonably inexpensively.
  • Finger thread guides are described, each having two trained as a cylindrical hollow body, formed of a metal alloy thread guide elements at the free end of their body, which form a yarn guide fork, in which a running on a cross-wound yarn during the winding process is performed.
  • the thread guide elements are either embedded positively or non-positively in the body or stored on additional support rods made of carbon fibers.
  • thread guide elements made of a metal alloy has the advantage that this material is much less sensitive to breakage than ceramic.
  • thread guide elements made of a metal alloy are less resistant to abrasion, that is, such Fingerfaden intro must be replaced significantly more frequently due to wear on the thread guide elements, as finger thread guides, which have ceramic thread guide elements.
  • the invention has the object to develop finger thread guides with interchangeable, relatively inexpensive thread guide elements, wherein the thread guide elements should be designed so that they can be securely fixed on one hand connected to the main body of the finger thread guide support bars, on the other hand, if necessary problem-free are interchangeable.
  • This object is achieved by a thread guide element for a finger thread guide, as described in claim 1.
  • the thread guide element is a replaceable positionable on support rods, thin-walled embossed part, which consists of a metallic material and has two coupled by a connecting web, slotted sleeves.
  • a trained thread guide element not only has the advantage that the embossing part can be fixed securely and always exactly aligned on the support rods, but can also in case of need, that is, if advised after a certain period of operation of the finger thread guide due to wear marks on the thread guide element a change of the thread guide element appears, can be exchanged quickly and easily.
  • embossed part tempered spring steel, which is cured after its molding.
  • tempered spring steel which is cured after its molding.
  • Such made of a tempered spring steel, hardened embossed part is on the one hand insensitive to shock loads and on the other hand also relatively wear-resistant.
  • the embossed part is subjected to a surface treatment after curing, with hard chrome plating preferably being used as the surface treatment.
  • a hard chromium-plated embossed part is not only characterized by a very low coefficient of friction, which leads to a gentle treatment of the thread to be traversed, but is also relatively insensitive to environmental influences.
  • the connecting web has at least one locking contour, which in the assembled state of the embossing part engages a locking projection on the main body of the finger thread guide form fit.
  • Such additional positive locking of the embossing part prevents the embossing part during the winding operation with time centrifugal force can shift outward. That is, the detent contour on the embossing part, in conjunction with a latching lug on the main body of the finger thread guide, ensures that the embossing part is reliably positioned on the support rods during its entire service life.
  • the slotted sleeves of the embossing part on a clear inner diameter which is matched to the outer diameter of the associated, designed as carbon fiber rods support rods.
  • the inner diameter of the slotted sleeves is chosen so that on the one hand in the assembled state, a bias is given, which is sufficiently large to handle the relative forces between sleeves and carbon fiber rods occurring during operation frictionally and on the other hand is small enough to pull up the sleeves on the carbon fiber rods to avoid damage as possible.
  • An appropriate dimensioning of the sleeves and support rods allows in case of need, the easy replacement of a worn stamping, but still ensures a reliable locking of the stamping on the support rods.
  • a device which facilitates the assembly of the embossing part on the support rods or the disassembly of the embossing part of the support rods.
  • a device may have various configurations, but preferably always has a clamping device for fixing the main body of the finger thread guide and a tool for lifting the locking contour of the embossing part of the locking projection of the body and the axial displacement of the embossing part on the support rods.
  • the Fig. 1 shows a front perspective view of the upper part of a workstation 1 of a cheese producing textile machine.
  • workstations 1 usually have a winding unit housing 4 equipped with an input device 3, which, inter alia, also accommodates a workstation-specific control device 5.
  • a winding device 6, which essentially consists of a creel 7 for holding a cross-wound bobbin tube 8, a bobbin drive roller 9 and a thread traversing device 2 for traversing a bobbin, is arranged on the winding head housing 4 exists during the winding operation on the cheese reel 8 and a cheese winding yarn.
  • the finger thread guide 10 is in turn connected via a fastening and locking element 17 to the motor shaft 18 of a reversible drive device 12, which in turn via a control line 13 with the workstation's own control device. 5 connected is. That is, the finger thread guide 10 can be controlled via the control device 5, so that during the winding process, for example, the thread laying speed and / or the width of the thread laying can be set exactly.
  • the Fig. 2 shows a equipped with a thread guide element 11 according to the invention finger thread guide 10, on a larger scale.
  • the finger thread guide 10 has a made of a plastic base body 14, in which during the manufacturing process support rods 15, 16 and a fastening and locking element 17 were cast with.
  • the carbon fiber rods formed as support pins 15, 16 are significantly longer than the female plastic body 14 receiving them formed. This means that the support rods 15, 16 protrude clearly beyond the base body 14 in the region of the free, narrow end of the main body 14 and thereby form support elements for a thread guide element 11 of the finger thread guide 10.
  • the arranged on the support rods 15, 16 thread guide element 11 is inventively designed as a stamping member 19 and has, as in particular also from Figure 3 clearly seen, two slotted sleeves 20A and 20B, which are coupled via a connecting web 21.
  • the slots of the sleeves 20A, 20B are arranged so that they point outwards, that is, the slots are positioned so that it is always ensured that during the Fadenchangtechnik the leadership of the thread through the slots can not be affected.
  • the slotted sleeves 20A, 20B are also with respect to their clear inner diameter d on the outer diameter D of the support rods 15, 16 is started. That is, the clear inner diameter d of the slotted sleeves 20A, 20B is selected so that the sleeves are fixed after their mounting on the support rods 15, 16 with a certain bias on the support rods.
  • the bias is preferably chosen so that on the one hand after assembly ensures a secure hold of the slotted sleeves 20A, 20B on the support pins 15, 16, on the other hand during assembly a relatively easy mounting of the sleeves on the support rods is possible. This means that damage to the support rods 15, 16 made of a carbon fiber material should be avoided as much as possible during assembly of the embossing part 19.
