Definitions

  • Traversing thread guides of the type mentioned are known in a variety of configurations from the prior art. At the workstations of a textile machine producing cross-wound bobbins, these are used to evenly wind a continuously fed thread onto a take-up spool that is put into circulation, the thread being moved back and forth in the axial direction of the take-up spool by means of the traversing thread guide.
  • the traversing thread guide performs an oscillating movement along a longitudinal axis of the traversing rod adjacent to the surface of the take-up spool and parallel to its axis, which leads to a uniform winding of the thread on the take-up spool.
  • the thread guide element has a thread insertion slot, via which the thread to be wound on the take-up spool enters the thread guide channel of the thread guide element, through which the thread is guided along the cross-wound bobbin during the oscillating movement of the traversing thread guide.
  • the thread guide element is positioned as close as possible to the winding point, ie the point where the thread runs onto the bobbin.
  • the nip area between a bobbin drive roller and the winding bobbin is reduced, which increases the risk of the thread guide element touching or even getting caught on the cheese.
  • the bobbin surface is not perfectly smooth but rather has a wavy surface.
  • damage to the holding frame, the thread guide element or the entire traversing thread guide can also occur, which tears off due to the acting transverse forces.
  • the object of the invention is to provide a traversing thread guide which ensures reliable thread transfer while avoiding the risk of snagging on the surface of the bobbin.
  • the wall sections each have a supporting surface formed by a plane on their upper side facing away from a base surface of the thread guiding element.
  • the wall sections are half-shell shaped bodies which are connected to the base of the thread guide element and extend over an area above the base of the thread guide element and delimit a thread guide area between the base and the wall sections.
  • the wall sections are spaced apart transversely to the running direction of the thread through the thread guide channel and thus form a thread insertion slot through which the thread to be guided enters the thread guide channel running below the thread guide slot, based on the position of use.
  • the upper sides of the wall sections which face a cross-wound bobbin in the position of use, each have a support surface which is formed by a plane, i. H. any straight line through any two points of the support surface lies entirely in the same plane.
  • a flat support surface on the thread guide element By forming a flat support surface on the thread guide element, a defined surface is provided on the traversing thread guide, which surface can come into contact with the cross-wound bobbin during winding operation.
  • the planar configuration reduces this considerably Measure the risk that there is a snagging of the thread guide element with the thread winding arranged on the cheese. If the support surfaces come into contact with the surface of the cross-wound bobbin, this reliably slides off the surface of the cross-wound bobbin, even with coarse windings, so that there is no snagging or the risk of snagging is significantly reduced. Trouble-free winding operation is thus guaranteed via the fundamentally freely selectable dimensioning of the support surface.
  • the alignment of the individual support surfaces of the two wall sections can basically be freely selected. In principle, there is also the possibility of arranging the supporting surfaces of the two wall sections in different planes. According to a particularly advantageous embodiment of the invention, however, it is provided that the supporting surfaces are arranged in a common plane.
  • the two support surfaces of the wall sections arranged adjacent to one another lie in a common plane, as a result of which a common support surface arranged at a uniform distance from the surface of the cross-wound bobbin is formed, which additionally reduces the risk of snagging with a winding arranged on the cross-wound bobbin , after the two support surfaces together form a total support surface arranged at the same distance from the surface of the cross-wound bobbin.
  • the design of the support surfaces can also be freely selected. According to an advantageous embodiment of the invention, it is provided that the support surfaces are aligned parallel to the base surface of the thread guide element.
  • This embodiment of the invention represents a particularly simple and inexpensive construction of the traversing thread guide which, with a corresponding arrangement relative to the cross-wound bobbin, reliably and effectively minimizes the risk of the thread winding snagging on the cross-wound bobbin.
  • the support surfaces are inclined towards one another and/or in the direction of an end face of the thread guide element.
  • the support surfaces are inclined towards one another, it is provided that the support surfaces, starting from their outer, lateral edges extending in the direction of the yarn travel, in decrease or increase towards the thread insertion slot. In other words, the support surfaces are at a smaller or greater distance from the base surface in the area of the thread insertion slot than in the area of the outer side edges of the support surface.
  • the planes of the support surfaces are at an angle of more than 140°, preferably more than 160°, particularly preferably 175° cut up to 195°.
  • the angles given are the angles enclosed by the planes of the support surfaces.
  • the slight inclination of the support surfaces produced by this angle increases the security against the thread guide element getting caught.
  • the tops of the wall sections are rounded in the area of their inner edges, front edges, side edges, secondary edges and/or rear edges, preferably with a radius of 0.3 to 7 mm, particularly preferred 0.3 to 4mm.
  • the inner edges are the edges of the wall sections that face one another and delimit the thread guide slot.
  • the edges of the wall sections running in the transition area between the support surfaces and the end faces are referred to as front edges.
  • the side edges run between the support surfaces and the side surfaces that extend in the direction of the running of the yarn.
  • the thread guide element has secondary edges if, according to an advantageous embodiment, it is provided with lateral and front transition sections on the wall sections, with the secondary edges extending between these areas.
  • the trailing edges are the sections of the wall sections that are oriented opposite to the running direction of the yarn.
  • a rounding of one or more edges additionally reduces the risk of the thread guide element snagging on the surface of the cheese. through the Roundings are generally formed in the areas closest to the cross-wound bobbin in such a way that they do not form a point of attack for the thread arranged on the cross-wound bobbin.
  • the design of the wall sections in particular the shape of the support surface in the area of the upper sides, can in principle be freely selected, with the wall sections usually having at least one upper side spaced from the base surface with the support surface and a front surface and side surface extending between the upper side and the base surface.
  • the wall sections each have a lateral transition section in the region between the support surface and a side surface, which falls in the direction of the side surface.
  • the lateral transition section is a section that rises from the side surfaces in the direction of the support surfaces, through which the thread guide element is rounded off in a supplementary manner and, in the event of contact with the cross-wound bobbin, there is particularly reliably no snagging.
  • the wall sections in the area between the end face and the side surface have front transition sections tapering towards the end face of the thread guiding element.
  • Such front transition sections also reduce the contact area of the thread guide element with the cheese and additionally reduce the risk of snagging.
  • the rear edges and the inner edges are connected to one another in a rounded manner.
  • a rounding, as well as the rounding of the trailing edge and inner edge represents an additional measure to increase the operational reliability of the traversing yarn guide.
  • the upper sides in the area between the rear edge and the supporting surface have a rear transition section which is inclined in the direction of the base surface.
  • the rear transition section is that section of the wall section which is directed counter to the thread running direction and which, thanks to this configuration, also contributes to preventing the thread guide element from getting caught.
  • the thread guide element can be connected in one piece to the base support or glued to it, by means of which the traversing thread guide can be attached to a traversing rod.
  • the thread guide element is detachably connected to the base support. This offers the possibility of manufacturing the thread guide element from a material that differs from the material of the base support, for example a ceramic material that has good sliding properties and low wear properties.
  • the thread guide element can be exchanged in a simple manner without a complete exchange of the traversing thread guide being necessary.
  • the orientation of the front face in relation to the base area can in principle be freely selected. According to an advantageous development of the invention, however, it is provided that the end face and the base face enclose an angle of 75° to 90°, preferably 80°. According to this embodiment of the invention, the end face is particularly preferably arranged slightly inclined in the direction of the base area. This alignment of the end face with respect to the base area additionally prevents the traversing thread guide from getting caught with the thread arranged on the cross-wound bobbin.
  • FIG 1 a work station of a textile machine producing cross-wound bobbins is shown in a schematic representation in the region of the cross-wound bobbin 22 .
  • Textile machines of this type generally have a large number of similar work stations arranged next to one another in a row, in which a thread 24 is wound onto a cross-wound bobbin 22 .
  • the thread 24 is in the direction of the cross-wound bobbin 22 is transported and wound up there.
  • the thread 24 runs through different units, for example a thread sensor (not shown here), before it runs onto the cross-wound bobbin 22, which is rotated by a bobbin drive roller 23 in a frictionally engaged manner.
  • the thread 24 running onto the cross-wound bobbin 22 is thereby traversed by a traversing thread guide 1, which can be displaced along a longitudinal axis of a traversing rod 21, and runs onto the cross-wound bobbin 22 in intersecting windings.
  • the traversing thread guide 1 has a thread guide element 3 made of a ceramic material and a base support 4 which is connected to the thread guide element 3 and by means of which the traversing thread guide 1 is detachably fastened to the traversing rod 21 .
  • the thread guide element 3 is arranged at the front end of the base support 4 viewed in the thread running direction F and has two wall sections 7, 8 connected to a base surface 16 and arranged at a distance from it in sections to form a thread guide section.
  • the wall sections 7, 8 are arranged at a distance from one another, viewed transversely to the direction of thread travel F, so that inner edges 20 of the wall sections 7, 8 that face one another and extend in the direction of thread travel F form a thread insertion slot 2, at which - viewed in the direction of the base surface 16 -
  • a thread guide channel 5 connects, through which the thread 24 extends during the winding process of the thread 24 onto the cheese 22 and during the adjustment movement of the traversing thread guide 1 along the traversing rod 21 alternately rests against the opposite sides of the thread guide channel 5.
  • the wall sections 7, 8 each have a support surface 9, which is formed by a plane, with the support surfaces 9 being in one plane in the illustrated embodiment common level are arranged.
  • the support surfaces 9 do not run parallel to the base surface 16 of the thread guide element 3, but rather have an inclined alignment, starting from their rear edges 11 and sloping down to the front end surfaces 13 running transversely to the thread running direction F.
  • the wall sections 7, 8 also have a lateral transition section 18, which extends between the support surface 9 and the side surface 12, which extends parallel to the direction of travel of the yarn F.
  • a front transition section 17 on the wall sections 7, 8 connects the end faces 13 to the side surfaces 12, with the front transition sections 17 being inclined starting from the side surfaces 12 in the direction of the thread guide channel 5, so that the thread guide element 3 tapers in the thread running direction F.
  • the wall sections 7, 8 each have a rear transition section 14 which is inclined in the direction of the base surface 16 in relation to the support surfaces 9.
  • the rear edges 11 delimiting the rear transition sections 14 counter to the direction of yarn travel F like the side edges 15 in the transition area between the lateral transition section 18 and the side surface 12, the secondary edge 19 in the transition area between the lateral transition section 18 and the front transition section 17 and the front edge 10 in the Transition area between the support surface 9 and the end face 13 rounded.
  • the facing inner edges 20 of the wall sections 7, 8 in the area of the thread insertion slot 2 are rounded.
  • the thread guide element 3 made of a ceramic material is connected to the base support 4, which has a fastening recess 6 for fastening to the traversing rod 21 for receiving suitable fastening means.
