Definitions

  • the invention relates to a winder for automatic bobbin changing according to the preamble of patent claim 1.
  • hooks are provided for lifting and laying the thread when changing the bobbin above and below the position of the mandrel fitted with the new sleeve, which hooks can be pivoted about approximately vertical axes.
  • the thread guide is not sufficiently precise, particularly as a result of the catch hooks swinging through. Therefore, it is not always guaranteed that the cut end of thread will be spooled over by the knot wrap on the new tube. It occasionally hangs freely and can get caught when the spool is ejected. It also happens that the thread slides laterally from the full sleeve when folded over to the new sleeve.
  • the invention has for its object to improve a winder according to the preamble of claim 1 so that an absolutely exact thread guidance is guaranteed when changing the bobbin. This is said to cause the unwanted specified Effects are avoided.
  • Claims 2 and 3 contain advantageous constructive refinements of the invention.
  • the winding machine consists of a housing 1-, a coil turret 3 which is rotatably mounted on the housing 1 about its axis 2 and a carriage 4 which can be moved back and forth at right angles to the axis 2 for the purpose of adaptation to the respective coil diameter, as by the arrow 5 indicated.
  • the coil turret 3 is equipped with two diametrically opposed mandrels 6, 7 which serve to receive coil sleeves.
  • two diametrically opposed, hook-shaped knives 8, 9 are attached, which grip over the edge of the attached sleeve 10.
  • the knife holder forms the stop for the sleeve 10.
  • an embodiment was selected for the drawing in which only a single sleeve or coil is seated on each mandrel.
  • a traversing device 12 with a traversing thread guide 13 is arranged on the carriage 4 above a pressure roller 11.
  • the traversing range is limited by the dash-dotted lines 14, 15 shown in FIG. 2.
  • the traversing area ends, in particular on the side facing the housing 1, at a certain distance from the edge of the attached sleeve 10.
  • the end area of the sleeve not swept by the traversing i.e. the area between the level of the knives 8, 9 and the adjacent end of the traversing area is the so-called knot winding area 16.
  • An approximately vertical bar 17 is attached to each side of the slide 4.
  • Two round guide rods 18, 19 are mounted in these two lateral strips, one above the plane of the axis of the mandrel 6 facing it and the other below this plane.
  • sheets 20, 21 are firmly connected by lateral holding plates 22, 23.
  • the sheets 20, 21 engage in the Darge in Fig. 1 with solid lines , approximately horizontal engagement position like pliers, but at a distance, around the mandrel 6 equipped with an empty sleeve 10.
  • the holding plates 22, 23 are connected to one another by an articulated coupling rod 24 in such a way that the joint 25 on the upper holding plate 22 lies on one side of the plane defined by the two rod axes, but the joint 26 on the lower holding plate 23 the other side of this level.
  • the piston of a cylinder 27, which is articulated on the base plate of the slide 4 acts on the holding plate 22. By actuating the cylinder 27, the two sheets 20, 21 can simultaneously be pivoted back into the almost vertical positions 20a, 21a, indicated by dash-dotted lines.
  • the leading edge 28 of the upper plate 20, which extends substantially over the entire length of the mandrel 6 is parallel to the axis of mandrel 6. In the engaged position, it lies approximately in the middle above the Verbindun g s-line between the traversing yarn guide 13 and the axis of the mandrel 6. It is provided approximately in the middle of the knot winding area 16 with a hook-like projecting stop 29.
  • the front edge 30 of the lower plate 21 also runs parallel to the axis of the mandrel 6. lies approximately in the vertical tangential plane of the mandrel 6 facing away from the carriage 4. It is also provided with a hook-like projecting stop 31, which, however, lies in the traversing area, and not far from the center.
  • a cylinder 32 Between the two rods 18, 19 there is a cylinder 32 with a piston rod 33 which carries a cross member 34.
  • Two rings 35, 36, 37, 38 are fastened to the two ends of the crossmember 34 reaching the rods 18, 19, one 35, 37 on one side of the traverse, the other 36, 38 on the other side.
  • the rings sit on the rods 18, 19 and are movable relative to them in the longitudinal direction, but non-rotatable.
  • a finger 39 is attached to the ring 36, which sits on the upper rod 18 in FIG. 2 to the right of the cross member 34.
  • a finger 40 is attached on ring 37, which is on lower rod 19 in Fig. 2 to the left of the crossbar, i.e. that is, at an angle to the finger 39, is seated.
  • the fingers 39, 40 are arranged at right angles to the rods 18, 19, extend in the engagement position approximately horizontally from the slide 4 in the direction of the turret 3 and extend with their free ends beyond the edges 28, 30.
  • the fingers 39, 40 maintain their relative position to the sheets 20, 21 because of their non-rotatable arrangement relative to the rods 18, 19, i.e. the free ends of the fingers 39, 40, in particular that of the upper insert, are at a short distance from the edges 28, 30.
  • the sheets 20, 21 and the fingers 39, 40 are in the folded-back position in which they have no function. As indicated by dash-dotted lines in FIG. 2, the fingers 39, 40 are moved back beyond the center of the traversing area.
  • the turret 3 pivots through 180 ° in the direction of arrow 41, so that the full spool reaches the right. In this position it is indicated by the circular line 42.
  • the carriage 4 moves in the direction of the still empty spool 10 of the other mandrel, which is now pivoted into the operating position.
  • the thread 43 which is guided around the empty tube 10 is initially wound even further as the traversing continues on the full bobbin.
  • the upper plate 20 touches the thread 43 with its leading edge 28, which is designed as a guide rail, and lifts it out of the traversing thread guide 13. As a result, the thread moves - regardless of the point at which it was lifted out of the traversing thread guide - towards the center of the traversing region.
  • the front edge 30 of the lower plate 21 also touches the thread.
  • the fingers 39, 40 move synchronously out of their rest position towards the end of the sleeve 10 at which the knives 8, 9 are arranged. As a result, the thread 43 is guided along the guide rails 28, 30.
  • the upper finger 39 moves up to the stop 29.
  • the thread is guided precisely in a narrow opening with little play.
  • the lower finger 40 moves a little further, namely to ; beyond the knives 8, 9 and the end of the sleeve 10.
  • the piece of thread guided around the sleeve 10 therefore runs obliquely to the edge of the sleeve. It lies on the sleeve in the upper area and extends beyond the sleeve edge in the lower area, penetrating the plane in which the knives 8, 9 rotate.
  • the thread 43 is held at a safe distance from the edge of the full bobbin 42 by the stop 31 of the lower plate 21, so that it cannot slip off the edge under any circumstances.
  • the fingers 39, 40 initially remain in the advanced position.
  • the following thread forms a small winding on the sleeve 10, which lies on the cut end of the thread.
  • the metal sheets 2Q, 21 fold back.
  • the fingers 39, 40 move back to the rest position.
  • the thread moves now move freely towards the center of the traversing area and is thereby gripped by the traversing thread guide 13. Then the construction of a new coil begins.
