  • the present invention relates to a device for winding a thread on a bobbin, with a pointer-like lever mounted on an axis of rotation, which can be driven in an oscillating manner Laying the thread in the longitudinal direction of the bobbin.
  • the invention is now to provide a thread laying unit, which also in allows an undisturbed operation in an environment with a lot of fiber flying.
  • Each thread laying unit has a single position control and thus the use of any Wrapping laws may be possible.
  • the device at the beginning mentioned type the axis of rotation into the interior of a dustproof housing and is connected inside a housing to a drive having a motor.
  • the device according to the invention makes it extremely immune to Dust from fiber fly.
  • a first preferred embodiment of the device according to the invention is characterized in that that said drive is a drive member fixed on the axis of rotation and Motor driven drive means for this includes, the drive member and Drive means are designed so that a reduction between the motor and the axis of rotation consists.
  • the reduction has the advantage that the greatest moment of inertia is caused by the thread laying lever and the drive element is formed, acts as little as possible on the motor, so that an inexpensive drive motor with relatively low power can be used.
  • a second preferred embodiment of the device according to the invention is characterized in that that the drive means by a drive wheel which can be driven by said motor and by two traction elements anchored to it with one end, such as strings, wire ropes or belts are formed, the traction elements with their other end on the drive element are attached and each traction element for driving the drive element in one of the two stroke directions is provided.
  • This design of the drive means has the advantage that the inertial forces occurring are low are. Since two traction elements are used, one of which drives the drive element is naturally tense, a possible relaxation of the other plays Switzerlandorgans in the area of movement reversal points do not matter, so a very high Traversing speed and also very high positioning accuracy of the thread laying lever is achieved.
  • a third preferred embodiment of the device according to the invention is characterized in that that the motor is designed as a stepper motor and that a sensor for detection the passage of the thread through the center of the stroke and the signal from the sensor Control electronics of the stepper motor is supplied.
  • the control electronics are also fed the applicable winding laws, so that the control electronics always "knows" how big the stroke has to be and how many Steps of the stepper motor correspond to this stroke.
  • the sensor checks whether between two consecutive passes through the center of the stroke actually the correct number of times Steps has been taken and gives a corresponding control signal to the in the event of a deviation Stepper motor. Since the stepper motor at most steps but never lose more steps than can be made a controlled operation for small and medium-sized companies Speeds possible. In addition, this control is with a suitable choice of the sensor very inexpensive.
  • the sensor is preferably attached to the drive element and as a position transmitter acting magnet and a detector fixedly arranged in the center of the stroke.
  • the Housing and the drive member are preferably made of a suitable plastic, so that the whole thread laying unit can be manufactured at very low cost and therefore for use in large quantities on machines with many individual positions suitable is.
  • the winding unit of a production machine shown in the figures consists essentially of a motor drivable spindle 1 for receiving a coil sleeve 2, on which a coil 3, for example a cheese, is wound up, and from a thread laying unit 4 for laying a thread F which is drawn off from a supply spool, not shown.
  • the coil 3 lies along a surface line on a freely rotatable roller 5, which is on a suitable carrier part the production machine is mounted.
  • Fig. 2 which is a variant of the thread laying unit 4 shows, the spindle 1, the coil sleeve 2, the coil 3 and the roller 5 are not shown.
  • the thread laying unit 4 which is used to produce the desired winding, contains as The most important element is a finger or pointer-shaped thread guide 6, which is motorized driven axis of rotation 7 is mounted.
  • the axis of rotation 7 is perpendicular to the coil axis and oriented perpendicular to the plane of the drawing, so that the thread guide 6 during operation of the winding unit performs an oscillating movement in a plane perpendicular to the axis of rotation 7.
  • the thread guide 6 is provided at a free end with a longitudinal slot 8 in which the thread F is led.
  • a guide rail 9 is arranged in front of the thread guide 6, which is partially wrapped in thread F.
  • the thread F does not run as shown shown supply spool to the guide rail 9 and from this through the longitudinal slot 8 of Thread guide 6 to roller 5.
  • the mutual position of thread guide 6 and guide rail 9 and the length of the longitudinal slot 8 are chosen so that the thread F during the movement of the Thread guide 6 does not touch the bottom of the longitudinal slot 8.
  • the thread guide 6 is depending on the direction of rotation of the axis of rotation 7 in one direction or the other swiveled and sweeps over a swivel angle of about 40 ° to 60 °.
  • the axis of rotation 7 is guided in the interior of a dustproof housing 10, which contains the drive of the axis of rotation 7 or at least essential parts of this drive.
  • a dustproof housing 10 which contains the drive of the axis of rotation 7 or at least essential parts of this drive.
  • the front of the housing 10 facing the viewer is omitted.
  • a wing-like drive member 11 of the shape of a Angular segment or circular sector fixed.
  • the attachment point of the drive member 11 is in the Area of its central angle or tip.
  • On the circular arc surface of the drive element 11 are the one ends of two pulling members running away in opposite directions 12 attached, which are formed by strings, wire ropes or straps.
  • the traction elements 12 run from the drive member 11 via deflection rollers 13 to a motor 14 driven Driving wheel 15, on which they are anchored with their other ends and which they several times embrace.
  • the drive wheel 15 and the deflection rollers 13 spanned level obliquely to the level of the drive member 11, the two levels in by the from the deflection rollers 13 to the attachment points on the drive member 11th Touch the traction elements 12 formed straight lines.
  • the slope between the two levels is necessary because the drive wheel 15 outside the plane of the drive member 11 must be.
  • the drive wheel 15 also symbolizes the motor 14, which is in this variant is located inside the housing 10, which is small enough of the engine is possible.
  • the motor can of course also be next to the drive wheel 15, for example below this, arranged and with the drive wheel via a gear or the like be connected.
  • the motor 14 is arranged outside the housing 10 and the drive shaft 16 of the drive wheel 15 is through the front housing wall to the outside guided.
  • the respective passage opening is also in the drive axis 16 dust-tight sealed in the housing wall with an O-ring.
  • the drive axle 16 must also pass through the drive member 11, which is connected to this Purpose of a said pivot angle of the drive member 11 of about 40 ° to 60 ° Breakthrough of the type indicated in Fig. 2.
  • the arrangement of the motor 14 outside the housing 10 has the advantage that with the discharge the engine heat no problems arise.
  • the one with the reference symbol 17 designated control electronics of the motor 14 arranged outside the housing 10 his. If the motor 14 is arranged outside the housing 10, the deflection rollers 13 are for Tensioning the tension members 12 resiliently mounted. When the motor 14 is arranged inside the housing is, it is mounted so that the drive wheel 15 acts as a pretensioning member (see EP-A-0 829 444).
  • Motor 14 is preferably a stepper motor.
  • the housing 10 and the drive element 11 are for example made of an inexpensive plastic, preferably injection molded.
  • the drive member 11 carries one on its front, near the circular arc-shaped end face Position transmitter 18, which is preferably cast into the drive element 11 Magnet is formed.
  • the position transmitter 18 is a detector arranged in the middle of the stroke 19 assigned, the signals of which are supplied to the control electronics 17.
  • the detector 19 can be arranged inside or outside the housing 10; in the latter case (Fig. 1) the housing material must be magnetically permeable.
  • the control electronics 17 contains the winding laws to be applied to the winding unit in question or receives this from a central machine control and controls depending on the Diameter of the coil 3 the number of steps of the motor 14.
  • the through the position transmitter 18 and sensor formed detector 19 checks whether between two successive passes of the position sensor 18 is actually carried out by the middle of the stroke, the correct number of steps is and gives a corresponding control signal to the stepper motor in the event of a deviation. Since the stepper motor at most steps, but never lose more steps than prescribed can therefore be controlled operation at low and medium speeds possible.
  • an encoder can be arranged on the drive axis (motor shaft) 16 and this can be assigned a suitable scanner (see also EP-A-0 838 422). Aggregates for highest thread speeds you can use an energy storage device like that in EP-A-0 838 422 described type can be equipped.
