Definitions

  • the innovation relates to a device for automatically pulling in the outer thread end of balls in each of the balls wound by means of a winding arm on a winding mandrel.
  • a device of the type mentioned is described in DE-PS 25 13 144. It is therefore known to place the end of the thread by means of the winding arm and with the aid of a thread guide over the end face of the tubular free end of the winding mandrel protruding from the ball and after cutting the end of the thread by negative pressure into the tube suck in while the ball is still on the mandrel. Despite additional support means provided for the end of the thread on the end of the intake pipe, malfunctions frequently occur as a result of blockages by threads and lint.
  • the previously closed banderole is pushed overhead onto the ball while it is still sitting on the winding mandrel.
  • the trimmed outer thread end is gripped and fixed by the banderole.
  • it can be pulled out of the sleeve relatively easily during transport and handling of the balls, which is felt to be a defect.
  • the innovation is therefore based on the object of creating a device of the type mentioned which is very simple and cheap, but on the other hand very reliably pulls the outer thread end into the interior of the ball.
  • the free end of the winding mandrel protruding above the ball is designed as a hook head, in the hook mouth of which the thread end can be inserted and can thus be drawn into the ball when the ball is removed from the winding mandrel.
  • the hook head can be freely rotated about the central longitudinal axis of the winding mandrel and by an eccentrically arranged weight on it in relation to the axis of rotation Standstill of the winding mandrel in a predetermined position deviating from the vertical can be moved into a certain rotational angle position.
  • the outer thread end can be moved directly and solely by means of the winding arm into the hook jaw turned by the weight into the correct position be inserted.
  • the hook mouth should pick up the end of the thread and hold it when the ball is pulled off the winding mandrel so that it is drawn into the ball, but on the other hand care must be taken to ensure that the hook mouth does not prevent the ball from being pulled off the winding mandrel.
  • the hook jaw consists of an insertion slot which extends radially from the outside inwards and axially in the oblique direction from the free end of the hook head to the ball and from an adjoining axially extending slot Skein of extending slot exists.
  • the hook mouth should hold and guide the outer thread end when pulling the ball off the winding mandrel, but should not exert a stronger pull on the thread end, because otherwise the ball will be deformed.
  • a further expedient embodiment of the innovation provides that the axially outer end of the hook mouth is formed by the peripheral surface of a pin or bearing inserted into the hook head.
  • the innovation has the significant advantage that the hook head can still be retrofitted to already used coil winding machines, preferably on those in which previously closed banderoles are pushed overhead onto the finished wound balls. This then leads to the fact that with these automatic winding machines the outer thread ends previously only defined by the banderole can now be fixed inside the ball. Even if, in individual cases, one end of the thread is not correctly gripped by the hook mouth and should be pulled into the ball when the ball not provided with the banderole is pulled from the winding mandrel, there is no interference because the end of the thread is still at least gripped and fixed by the banderole.
  • Yet another advantage of the innovation is that no be for the retraction of the outer thread end in the ball special drive is needed. Accordingly, the proposed mechanical gripping of the thread end and its pulling into the ball during the pulling movement of the ball from the winding mandrel is a new manufacturing process which is very advantageous because of its simplicity and reliability.
  • FIG. 1 shows, as a detail of an automatic coil winder, a winding mandrel 12 which is rotatably mounted on a pivotable mandrel bar 10 and on which a coil 16 can be wound by means of a rotatingly driven winding arm 14.
  • the winding arm 14 rotates about a horizontal axis
  • the winding mandrel can be pivoted in the vertical central plane of the axis of rotation of the winding arm 14 by means of the mandrel bar 10.
  • the winding mandrel 12 performs a rotary movement about its longitudinal axis.
  • the winding mandrel 12 is preferably composed of individual struts 18 which are evenly distributed over the circumference and are articulated in such a way that they can be radially expanded or contracted. During the winding process, the struts 18 assume the spread position, and for the axial pulling of a completely wound ball 16 from the winding mandrel 12, the struts 18 are drawn in radially.
  • Such expandable mandrels are known (see. DE-PS 25 13 144) and common in practice. It is therefore not necessary to go into them in detail.
  • the ball pick-up 20 consists, in a known embodiment, of a plurality of gripper-shaped movable arms which, in this phase, where they are guided over the ball-1, already carry a prepared, closed band 22, which is applied to the ball 16 on the outside in this way. Thereafter, the ball 16 is pulled upwards in the direction of the arrow by the ball pickup 20 from the winding mandrel 12 shown in FIG. 2 only with its upper end for the sake of simplicity.
  • the hook head 5 essentially consists of a stationary lower part 26 and an upper part 28 which can be rotated relative to it about the longitudinal axis.
  • the lower part 28 is screwed tightly to the winding mandrel 12 by means of screw thread 30.
  • the upper part 28 is rotatably mounted on the lower part with the aid of a ball bearing 32.
  • the upper part 28 is provided or formed with a weight 34 arranged eccentrically to the axis of rotation of the bearing 32, which has a tendency to assume the lowest possible position in the case of an inclined position of the hook head which deviates from the vertical and thereby the upper part 28 into a certain position Angular position rotates.
  • the upper part 28 is shaped or milled in such a way that a hook jaw 36 is formed.
  • This consists of an insertion slot 38, which runs obliquely downwards from the outside radially and an adjoining retaining slot 40, which extends axially away from the ball.
  • a ball bearing 44 is mounted on a bearing pin 42 according to FIG. 5 its outer Circumferential surface comes into contact with a thread end 24a inserted into the hook jaw 36.
  • the exemplary embodiment according to FIGS. 6 and 7 largely corresponds to the hook head according to FIG. 5, only the ball bearing 44 is replaced by a pin 46 which cannot be rotated into the upper part 28.
  • the thread end 24a then does not slide over a rotatable bearing surface, as shown in FIG. 5, but over the fixed but smooth peripheral surface of the pin 46. Since the upper part 28 is essentially cylindrical on the inside according to FIG. 6, the ends of the pin 46 are 7 also rounded accordingly, so that the pin fits exactly into the upper part 28.
