Definitions
- Thread withdrawal device for a cross-wound textile machine
- the invention relates to a thread withdrawal device for a cross-wound textile machine according to the preamble of claim 1.
- Textile machines producing cross-wound bobbins each have a thread take-off device in the area of their work stations which extracts the thread produced in a spinning device from the spinning device during the spinning operation and continues to convey it at a constant delivery speed in the direction of a winding device where the thread is wound into a cross-wound bobbin becomes.
- the thread withdrawal devices consist either, as described for example in DE 44 32 240 Al or in DE 39 17 047 Al, from a machine-length drive shaft, in each case a pivotally mounted pinch roller rests in the field of jobs, or the thread take-off devices each have a single motor Drive up.
- Such single-motor driven yarn draw-off devices are shown and described for example in DE 101 39 075 A1.
- These thread take-off devices each have a relatively large, single-motor driven thread withdrawal roller and a much smaller, pivotally mounted pinch roller, which is taken frictionally engaged during the spinning operation of the thread withdrawal roller.
- the thread take-off roll which is preferably reversibly drivable via a stepping motor, generally consists of a rotationally symmetrical die-cast or injection-molded body. That is, from a one-piece cast body having an inner mounting hub, an annular outer periphery and an intermediate, closed connection disc.
- a disadvantage of these proven thread take-off devices is the often poor cooling of the thread take-off roller drives. That is, in these known yarn draw-off devices, overheating of the yarn withdrawal roller drives may occur, in particular in unfavorable climatic conditions, during the spinning process.
- the present invention seeks to develop a yarn withdrawal device, in which during the spinning operation always sufficient cooling of the thread take-off roller drive is guaranteed.
- the thread take-off roll has a rotationally symmetrical base body which is designed such that during the rotation of the thread take-off roll, an air flow is created which cools the thread take-off roll drive.
- the thread take-off roller operates in the manner of a fan.
- Thread take-off roll in one piece, but largely open.
- the main body of the thread take-off roller on an outer bearing receptacle for fixing a thin-walled, profiled metal ring, an inner hub for attachment of the thread take-off roll on the motor shaft of the thread take-off roller drive and arranged therebetween air blades.
- the air blades initiate during the rotation of the thread take-off roll a clear, largely uniform air flow in the direction of the associated drive.
- the air blades are curved in the direction of rotation.
- the air blades have concavely curved surfaces which, when the regular thread take-off takes place in the direction of rotation of the thread take-off roll forward.
- the main body of the thread take-off roller is manufactured as an injection-molded or die-cast part.
- Such injection-molded or die cast parts are, in particular, if larger quantities are produced, relatively inexpensive and very accurate to manufacture.
- FIG.l perspective view of a job of a cheese-producing textile machine, with a single-motor driven thread withdrawal device and a thread take-off roll according to the invention
- FIG. 2 shows a perspective view of a thread take-off roll according to the invention with attached thread take-off roller drive.
- FIG. 1 shows a perspective view of a workstation 1 of an open-end rotor spinning machine.
- Such jobs 1 have, as is known and therefore shown only schematically, an open-end spinning device 2 for producing a thread 9 and a winding device 3, on which the thread 9 is wound into a cheese 8.
- the yarn 9 produced in the open-end spinning device 2 is thereby frictionally engaged by a yarn draw-off device 27, which can drive a yarn take-off roll 10 that can be driven by a single motor and a swivelable to the yarn take-off roll 10 entrained pinch roller 14, from which the open-end
- a pivotally mounted Anspinncousorgan 16 is also arranged, which after a yarn break through a suction nozzle 4 of the
- Reel 8 takes over retrieved thread 9 and prepares the thread end for re-spinning.
- a thread monitor 26 In the thread running direction behind the thread take-off device 27, a thread monitor 26, yarn storage devices 7 and 12 and a waxing device 5 are furthermore arranged.
- the yarn storage device 12 is designed as a vacuum-pressurizable storage nozzle, while the storage device 7 is designed as a mechanical yarn storage. That is, between two stationary Fadenleitorganen an adjustable Fadenleitorgan is arranged, which, acted upon by a stepping motor 28, is arranged to be movable relative to the yarn path.
- the winding device 3 is, as usual, from a creel 22 for rotatably supporting a cross-wound bobbin 8, a preferably via a reversible single drive 19 drivable Spulenantriebstrommel 23 and a Fadenchangier driving 24, which is driven for example via a stepping motor 20.
- a thread-centering device in the form of a pivotally mounted centering plate 17 can also be arranged, which, if required, can be folded by a drive 18 into the regular thread running path.
- work stations 1, as already indicated above have a suction nozzle 4, which is adjustable by means of a stepping motor 6 between a thread receiving position lying in the region of the winding device 3 and a yarn transfer position lying in the region of the spinning device 2.
- the thread take-off device 27 consists, as already indicated above, essentially of a drivable thread take-off roll 10, a swivelable to the thread take-off roll 10 and frictionally entrained by this pressure roller 14 and a thread take-off roller drive 13.
- the preferably designed as a stepper thread take-off roller drive 13 is in turn via a control line 35 at a workstation computer 25 connected.
- the thread withdrawal device 27 ensures both during the regular spinning operation for the removal of the spun yarn 9 from the open-end spinning device 2, as well as the Wiederanspinnen after a spinning interruption for the return of a prepared thread 9 in the open-end spinning device. 2
- the thread take-off roll 10 consists of a rotationally symmetrical basic body 15, manufactured, for example, by injection-molding or die-casting.
- the base body 15 in this case has a circular, outer bearing receptacle 29, on which a thin-walled, for example by high pressure internal deformation profiled metal ring 11, which preferably consists of steel or a stainless steel alloy, can be fixed.
- the thin-walled, profiled metal ring 11 is in contact with the yarn 9 during the winding operation and, in conjunction with the adjoining pressure roller 14, ensures that the yarn 9 is withdrawn continuously from the open-end spinning device 2.
- the main body 15 further has an inner hub 31, via which the thread withdrawal roller 10 can be fixed to the motor shaft 32 of the thread withdrawal roller drive 13.
- the air blades 33 initiate an air flow that cools the thread take-off roller drive 13.
- Thread take-off roller 10 are front and concave.
