Definitions

  • the invention relates to a drive unit for driving a turret winding head for winding roving on winding tubes.
  • rovings or lunts are produced, which are used as a template for the spinning to a fiber yarn, for example on a ring spinning machine.
  • the roving used for the template for ring spinning machines is usually made from a conveyor belt, which is warped on a drafting of the roving and then receives a slight rotation, so that the roving can be wound on a bobbin without distortion.
  • the given rotation may only be so high that the cohesion of the fibers for the winding and rewinding and the transport of the coils is strong enough.
  • this so-called protective rotation with regard to the distortion on ring spinning machines must be so low that no distortion disturbances occur in the further processing process.
  • the roving must be delayable despite the introduced protective rotation.
  • the conveyor belt used for the production of the roving consists of so-called short staple fibers.
  • fibers of cotton or mixtures of cotton fibers and man-made fibers are used.
  • dirt or short fibers and parts of fibers are removed from the conveyor belt and get into the environment.
  • flying components or resulting deposits pose a risk to the machine technology used.
  • the degree of soiling increases with changes in running conditions, in particular with an increase in the speed of the lint production.
  • winding machines which are suitable for continuous running at high speed threads and at a Spulhülsencic no change resp. Lower delivery performance.
  • a winding machine discloses, for example, the EP 1 053 967 .
  • the winding machine has a turret winding head, on which two bobbin spindles are held. A first bobbin is in a winding position and a second bobbin is in a doffing position. In the Dofferposition the full bobbins are removed from the mandrel and replaced by empty tubes. When the bobbins in the winding position are full, the turret is turned through 180 ° and the bobbin spindles swap positions.
  • the running threads are separated without interruption or reduction of delivery performance by the rotation of the revolver from the full bobbins and taken over by the empty tubes.
  • the spool pins are arranged horizontally.
  • the thread guide from which the thread changes to traversing is located at a certain distance from the traversing itself. This results in a longer path for the thread from the thread guide to the outermost position of the traversing, as if the traversing is in the middle position. Due to this, any movement of the traversing results in a certain delay.
  • the yarns processed in the described winding machines are endless threads made of a polymer. Therefore, as a rule, no dirt or flying dust as well as short fibers extracted from the fiber structure arise. In contrast, cotton processing is associated with a significant amount of dirt, dust and short fibers or fragments of fibers. This circumstance leads to the fact that cotton processing machines are equipped with cleaning and suction.
  • a revolver winding head according to the preamble of claim 1 is known from JP 7 133505 A known.
  • the object of the present invention is therefore to provide a device for winding roving, which enables a continuous roving of a roving and is able to keep the device from a raw material-related pollution, in particular should be maintenance-consuming components such as drives and bearings from contamination by flying around or Depositing dirt particles and short fibers are preserved.
  • the object is achieved by a revolver winding head for winding a roving with the features of independent claim 1.
  • the turret winding head comprises a closed housing, wherein a turret base plate is formed as a part of the housing.
  • a first spindle and a second spindle are arranged in the turret base plate outside the housing.
  • the first spindle is provided with a first drive and the second spindle with a second drive, wherein the drives are arranged within the housing.
  • the first and the second drive are each equipped with a fan.
  • an intake passage is provided on the intake side of the fan wheel, through which an intake of air through the impeller from outside the housing is provided.
  • the revolver winding head according to the invention is constructed in its design similar to the known turret winding heads from the man-made fiber technology.
  • the turret base plate is horizontal and the spindles mounted in the turret base plate are arranged vertically. This makes it possible to use according to the prior art flyer sleeves for winding. This has the advantage that there is compatibility with the subsequent final spinning processes and no rewinding or even retooling of the downstream machines has to take place. Flyer sleeves according to the prior art, for example, by the EP 0 927 696 disclosed.
  • the drive units include the motors and necessary gears and the power transmission elements such as belt drives or clutches and brakes or other equipment necessary for driving the various elements.
  • the turret base plate forms a part of the housing.
  • the motors for driving the spindles are equipped with a fan. Since during the winding process always one of the two spindles and thus also the associated drive is in operation, air is also routed to the cooling of the engine via the cooling fan via the corresponding fan. This circumstance makes use of the invention.
  • an intake passage On the suction side of the fan wheel, an intake passage is provided, which connects an opening in the housing with the suction opening of the fan wheel. As a result, we sucked air from outside the housing through the fan and blown it into the housing.
  • Each of the two spindle drives is provided with a separate intake duct for the respective fan wheel.
  • the two intake ports also connect two independent ports to the respective fan.
  • the intake ports are equipped with a filter. This filter prevents dust and dirt from being sucked in by a fan and inserted into the housing. Adapted to the dust concentration requirements within the housing, different types of filters can be used. Conceivable are simple mesh screens, filters made of textile fabric and other known from the prior art filter.
  • the housing is not made air or dustproof. Thus, no closure member is provided for the closure in the intake. Also, it is not necessary to seal the rotatable turret base plate against the housing wall.
  • the air drawn in by the operating fan is blown into the interior of the housing, causing an overpressure to the environment. If the overpressure reaches a certain value, the air escapes automatically through the existing deliberately created leaks into the environment.
  • the prevailing negative pressure in the housing corresponds to the pressure loss of all existing leaks and automatically adjusts itself due to the size of the leaks.
  • One of the leaks for example, is the intake passage of the inoperative drive of the spindle located in the doffer position. The prevailing in the interior of the housing overpressure ingress of contamination is avoided and it is given in a dusty environment high reliability.
  • the drive of a spindle is an electric motor with an attached fan.
  • hydraulic or pneumatic drives are provided for the power transmission from the electric motor to the spindle .

  • the turret base plate is held in a defined position.
  • the turret base itself can be driven by a motor which is provided with a belt or chain drive. It can also be provided a direct drive via a corresponding sprocket.
  • the air sucked in by the fan wheel of the drive in operation is supplied to the drive via a filter through the suction channel from outside the housing.
  • an overpressure arises within the housing, the size of which is determined by leaks present in the housing and the intake passage of the drive which is not in operation.
  • the air flowing outwards through the intake duct of the drive which is not in operation also leads to the cleaning of the filter installed in the intake duct and in the intake duct.
  • the amount of negative pressure can be determined by the number and size of the leaks in the housing.
  • the negative pressure and the type and size of the filter provided in the intake duct are selected such that self-cleaning of the filters in the intake duct results.

  • the traversing means 11 comprise a movable element which moves up and down along the winding tube 9, resulting in a uniform winding with roving of the, about the rotation axis 5 rotating, winding tube 10 results.
  • the second spindle 6 is in the representation of FIG. 1 in the doffing position.
  • the second spindle 6 has already been freed from the full winding tube.
  • the removal of full bobbins and the placement of empty bobbins 10 can be done automatically by appropriate manipulators or robots.
  • the spindle 6 is provided in its upper region with a fastening element 9.
  • the fastening element 9 is used to stabilize a winding tube 10 on the spindle 6.
  • An empty winding tube 10 is placed from above on the spindle 6 and then held by the fastener rotatably 9.
  • the fastening element 9 may be, for example, a pneumatic tensioning device, which is depressurized after placement of the winding tube and thereby undergoes a radial expansion, which results in a winding tube being clamped on the spindle 6.
  • the revolver base plate 2 When the winding tube 10 is provided with a full winding, the revolver base plate 2 is rotated about its axis 3 by half a turn (180 °) in the direction of arrow 8. As a result, the first and second spindles 4, 6 exchange positions.
