Definitions

  • the invention relates to a cylindrical winding tube according to the preamble of claim 1.
  • This winding tube is known from DE 39 23 305 A1 (IP-1650).
  • This winding tube is used to wind up a thread, in particular chemical thread, the thread being caught in "synchronism". Reference is made to the description of DE 39 23 305 A1.
  • the thread catch slot of the known bobbin tube consists of an insertion piece and a clamping piece.
  • the insert is so wide that the thread easily falls into the bottom of the insert.
  • the clamping piece is very narrow and serves to exert considerable tensile forces on the thread.
  • a thread trap is provided in the known winding tube in the area of the insertion piece, which does not hinder the radial penetration of the thread into the insertion piece, but blocks the radial exit from the clamping piece, preferably blocks it in a form-fitting manner.
  • the object of the invention is to improve the thread trap. It is particularly important that very high and very suddenly occurring thread forces act on the thread trap in the case of thick threads or threads of high strength. If the winding tube is wound out of cardboard or layers of paper, there is a risk that in such a case also consist of layers of paper Thread trap is torn apart layer by layer.
  • the solution results from claim 1.
  • the peculiarity of this solution is that the thread trap is formed by a locking edge formed on the sleeve, which covers the entire sleeve thickness, so that the thread always acts on the entire sleeve thickness and not only on individual layers of the sleeve.
  • the locking edge lies in such a way that the thread that has fallen into the opening of the drop-in piece - seen radially - runs below the locking edge. If the thread is now guided along the flank of the thread catch slot facing the axial center of the sleeve, it first falls into the bulge and is then gripped by the entire thickness of the locking edge and carried along. This creates an increasing wrap around the thread on the locking edge with the result that the thread increasingly constricts the paper layers of the winding tube that are exposed on the locking edge and thereby further solidifies the winding tube in this area.
  • the locking edge is essentially axially directed. You can also form an obtuse angle with the catch slot, as long as this angle is in the self-locking range, d. H. as long as there is no danger that the thread slips axially on the locking edge.
  • the locking edge can also form an acute angle with the catch slot. The resulting arrow-shaped projection must not be weakened inadmissibly. If the aspect of simple production is also taken into account, the axially parallel alignment of the locking edge appears to be particularly advantageous.
  • Figures 1 and 2 illustrate the structure and operation of the winding tube according to the invention.
  • the circular cylindrical winding tube 1 has the catch slot 2 at one end, adjacent to its end face.
  • the catch slot extends in the circumferential direction over an angle of z. B. 120 ° or more. If one assumes that both the surface of the sleeve 1 and the thread move in the direction of the arrow 3, the catch slot begins with an insertion piece 4.
  • This insertion piece 4 is distinguished by the fact that it has a relatively large width in comparison to the thread diameter .
  • the insert can z. B. extend over 90 ° of the coil circumference.
  • the clamping piece 5 then follows.
  • the clamping piece 5 has a small width relative to the thread diameter. The clamping piece is so narrow that it is suitable to exert considerable tensile forces on the thread.
  • a thread trap 6 lies in the area of the drop-in piece 4.
  • the thread 8 is drawn off by thread guide 14 by means of a suction gun, not shown, or a driven, full bobbin (cf. PCT / DE 89/00094).
  • the thread is delivered by a delivery unit 23, not shown, or the chemical thread is freshly spun and comes directly from the spinneret.
  • the winding spindle 15 with the empty tube 1 stretched thereon is driven essentially at a surface speed which corresponds to the thread speed.
  • the The winding spindle 15 has been moved into the thread run such that the direction of the surface movement of the winding tube corresponds to the thread running direction 3.
  • the thread is guided into the normal plane of the catch slot by a thread guide 23 lying in front of the winding tube 1 in the thread running direction. It is drawn off via thread guide 14, which is located somewhat to the side of the normal plane of the thread catching slot, specifically on the side facing the axial center of the winding tube.
  • the thread trap 6 is formed by a bulge 20 which is delimited by a locking edge 19 on the side facing the clamping piece 5.
  • the bulge affects the flank of the insertion piece of the thread catch slot, which faces the axial center of the sleeve.
  • the bulge 20 is located in an area of the insertion piece, in which the insertion piece extends to the inner circumference of the winding tube (area of an opening).
  • the ends 17 and 18 of this incised area are at such a distance from the blocking edge 19 that the thread dropped into the insert 4 forms a secant of the inner circumference of the winding tube, as shown in FIG. 2C.
  • the axial extent of the bulge 20 is not critical. It can be a few millimeters, in any case sufficient that there is sufficient length for gripping the thread.
  • the locking edge 19 has an axially parallel course in the exemplary embodiment. Under this condition, the bulge 20 is easy to manufacture.
  • the locking edge 19 can also form an obtuse angle with the flank of the thread catching slot.
  • the angle must not be chosen so large that the thread which is guided around the blocking edge 19 automatically slips in the direction of the insertion piece. In any case, there must be self-locking for the thread.
  • the locking edge can also form an acute angle with the flank of the insertion piece 4. It would be harmless if the thread in here on the locking edge Direction slips on the wedge gap 21 formed with the bulge 20. However, the arrow-shaped projection, which is formed here by the locking edge, must remain sufficiently strong to exert the forces required to tear the thread.
  • the thread guides 14, 23 on the one hand and the sleeve on the other hand are positioned so that the thread wraps around the sleeve in the normal plane of the catch slot, preferably at more than 90 ° and hardly more than 180 °.
  • FIG. 2A shows the rotational position of the winding tube, in which the front end of the insertion piece 2 of the catch slot has reached the point at which the thread 8 runs onto the winding tube.
  • Fig. 2B shows that as the winding tube continues to rotate, the thread falls into the sinker 4.
  • the insertion piece is chosen so large in its axial width that the thread reaches the bottom of the insertion piece without any major obstacle. It should be particularly mentioned that the insertion piece is essentially as deep as or deeper than the clamping piece of the catch slot to be described below. In its central area, however, the insertion piece is pierced down to the inner circumference of the winding tube 1. The ends of this pierced area 17 and 18 lie on a secant of the inner circumference.
  • the thread thus falls to the bottom of the sinker or forms a secant between the ends 17 and 18 of the pierced area to the inner circumference of the winding tube.
  • the thread running speed is slightly - in the order of 1% - greater than the translational speed of the catch slot or the sleeve.
  • the resulting Relative speeds do not have an effect in the form of frictional forces acting on the thread, since the insertion piece 4 is so wide that it does not significantly impede the thread.
  • the resulting thread tension forces and relative speeds are sufficient to pull the thread as deep as possible into the catch slot or the insertion piece and the clamping piece.
  • the function of the thread trap is shown with reference to FIG. 2C. It should be mentioned that the thread with the running direction 3 runs exactly in the normal plane of the catch slot 2, but that the thread center running over the thread guide 14 has a movement component in the direction of the longitudinal center of the winding tube. The deviation is a few degrees. As a result, the thread running out of the drop-in piece 4 in FIG. 2C rests against the flank of the drop-in piece, which faces the axial longitudinal center of the winding tube.
  • the thread comes past the bulge 20 by turning the winding tube further, it also slides into this bulge due to its laterally directed component. Since the bulge also lies in the penetrated area of the insertion piece 4, the thread which forms the secant to the inner circumference in this area passes under the blocking edge 19 which delimits the bulge 20. This locking edge opposes the thread coming out of the insertion piece against a form-fitting obstacle. If the locking edge has moved past the tangent between the roller 14 and the winding tube by further rotation of the winding tube, the thread is increasingly deflected at the locking edge. By means of this deflection, the locking edge is pressed together, so that the paper layers from which the sleeve is wound are pressed together and stiffened.
  • the thread is held on the bottom of the groove. It can therefore not be pulled radially out of the subsequent clamping piece.
  • the clamping forces that are exerted on the thread in the clamping piece therefore only have an effect in the circumferential direction and thread running direction, but not in a radial direction transverse to the thread. The clamping forces are therefore only converted into thread tension.
  • the clamping piece 5 is now designed so that very suddenly clamping forces are exerted on the thread. This happens because the clamping piece very suddenly narrows relative to the insertion piece to such an extent that strong frictional engagement or practically positive engagement occurs between the thread and the side walls of the catch slot. It must be taken into account here that multifilament chemical threads are involved which, in comparison with the winding tubes made of cardboard or layers of paper, offer multiple possibilities of engagement for a positive connection.
  • 2E shows a rotational position in which the thread 8 is deflected for the first time at the blocking edge 19 of the thread trap 6.
