Definitions

  • the present invention relates to a spinning machine with at least one spinning station, the spinning station comprising a spinning device with an inlet for a fiber material and an outlet for the yarn produced from the fiber material in the spinning device, a delivery device for feeding the fiber material into the spinning device and a winding device for Has winding of the yarn produced.
  • a method for removing an end portion of a yarn at a spinning station of a spinning machine before a subsequent piecing process comprising a spinning device with an inlet for a fiber material and an outlet for the yarn produced from the fiber material in the spinning device, a delivery device for the Has supply of the fiber material in the spinning device and a winding device for winding the yarn produced, and wherein after an interruption of the spinning process at least the end portion of the yarn to be removed is unwound from the winding device.
  • the object of the present invention is therefore to propose a spinning machine and a method for removing an end section of a yarn on a spinning machine before a subsequent piecing process, with the aid of which the piecing times can be shortened compared to the prior art.
  • the spinning station comprises a yarn end discharge which is arranged at least partially between the outlet of the spinning device (comprising, for example, a spinneret or a spinning rotor) and the winding device, and with the aid of which an end section of the yarn produced can be separated and removed from the remaining yarn ,
  • the removal of the yarn section not suitable for the piecing process can thus be carried out directly at the spinning station, specifically before a service robot or corresponding operating personnel arrives at the respective spinning station.
  • the yarn can be started immediately after the interruption for the subsequent one Prepare piecing process. While it will usually be necessary after a yarn break, Detaching the yarn end from the bobbin surface and then feeding it to the yarn end discharge (e.g. by means of a separate gripping device) opens up enormous advantages for the spinning station in accordance with the invention, in particular for performing a quality cut. In principle, it is thus possible to slowly throttle the production of the yarn after the detection of a deviation in a previously defined yarn parameter.
  • the units mentioned delivery device, winding device, take-off device
  • the yarn end is now at a defined position and can be fixed accordingly if necessary, for example with the aid of a pair of rollers of the take-off device. If the fixation finally takes place in the area of the yarn end discharge according to the invention, the yarn end can be reliably grasped by the yarn end discharge without additional handling means being necessary.
  • the end section of the yarn which does not meet the specifications is then unwound from the winding device, the end section in the case of slow throttling of the delivery speeds preferably corresponding at least to the section which was produced from the start of the throttling.
  • the unwound end section can finally from the yarn end discharge, for example, wound up or suctioned off and finally separated and discharged accordingly (e.g. into the area of a central collection point).
  • the yarn end discharge comprises a suction channel, via which the end section of the yarn can be sucked in and / or the separated end section of the yarn can be removed.
  • the suction channel can be connected to a central vacuum source of the spinning machine. It is of course also grateful to equip the suction channel with its own vacuum source, for example a Venturi nozzle, which is only put into operation if a corresponding end section of a yarn has to be removed at the respective spinning station.
  • the yarn end discharge comprises a cutting unit, by means of which the end section to be removed can be separated from the rest of the yarn.
  • a cutting unit by means of which the end section to be removed can be separated from the rest of the yarn.
  • the cutting unit is integrated in the above-mentioned suction channel, a compact unit is obtained, with the aid of which the end section to be removed can be both separated and removed, ie disposed of. If necessary, the cutting unit can be brought into the region of the end section of the yarn and / or can be switched on or off.
  • the yarn separation device of a yarn monitoring unit (“cleaner"), which can also be designed as a cutting unit if required.
  • the yarn separation device is preferably positioned between the suction channel of the yarn end discharge and the take-off device and monitors predetermined properties or the presence of the yarn produced in the area of the yarn monitoring unit.
  • a separate cutting device within the suction channel could finally be dispensed with in this embodiment.
  • the spinning station for. B. formed by a pair of draw-off rollers, take-off device for withdrawing the yarn from the spinning device, the yarn end discharge being arranged between the outlet of the spinning device and the take-off device.
  • the spinning station for. B. formed by a pair of draw-off rollers, take-off device for withdrawing the yarn from the spinning device, the yarn end discharge being arranged between the outlet of the spinning device and the take-off device.
  • the resulting yarn end can be fixed between the rollers of the take-off device if necessary, the fixing, i. H. the associated stopping of the take-off rollers can be initiated by a sensor which monitors the presence of a yarn at a defined point after the exit of the spinning device.
  • the take-off rollers finally release the yarn end before it is finally caught by the yarn end discharge and z. B. is sucked into said suction channel (with appropriate reverse rotation of the spool mounted in the winding device).
  • the advantage here lies in the fact that the yarn ends even then is still fixed by the take-off device at a defined point when the end section of the yarn is separated from the yarn end discharge and removed.
  • the robot that arrives on demand can finally grip the yarn end before the actual piecing process, so that time losses can be avoided by searching for the yarn end.
  • the winding device and / or the take-off device have a reversibly drivable drive unit. Even if it would be sufficient for the unwinding of the yarn section to be removed to equip the units mentioned with a freewheel device, it is advantageous if an active drive is possible against the conveying direction prevailing during the spinning process. In this way, a controlled unwinding of the end section of the yarn is possible, whereby an undefined overrun of the respective bobbins can be avoided.
  • the spinning machine has a multiplicity of spinning stations arranged next to one another, each spinning station comprising a separate yarn end discharge.
  • the spinning positions are independent of one another, so that the end section of the yarn which is unsuitable for spinning can always be removed at the spinning position at which re-spinning is to take place.
  • suction channel of the yarn end discharge is connected to a suction device of the delivery device.
  • suction devices are usually present, for example, in the area of a drafting device of an air spinning machine or a disintegrating roller of a rotor spinning machine and serve to remove fluff, dust or other contaminants. If the suction channel is now coupled to such a suction device, a separate suction device can be dispensed with.
  • the connection between the suction channel and the suction device of the delivery device can be done for example by means of pipe sections and / or corresponding flow switches.
  • a valve and / or a flow switch is assigned to the suction channel, with the aid of which the air pressure within the suction channel can be regulated.
  • the suction channel can be coupled to a central suction system of the spinning machine.
  • a vacuum or air flow is finally applied to the suction channel, which causes the yarn end to be sucked in.
  • the valve or the flow switch is advantageously controlled with the aid of a corresponding control unit, which in turn can be connected, for example, to a yarn sensor.
  • the winding device comprises a yarn traversing device, the yarn traversing device being associated with a yarn lifting device, with the aid of which the yarn can be brought out of the effective range of the yarn traversing device.
  • the yarn lifting device comprises a lifting element which can be moved relative to the yarn, preferably with the aid of a pneumatic cylinder.
  • the yarn finally runs over the lifting element and can therefore no longer come into contact with the traversing elements of the traversing unit.
  • the yarn lifting device, or the pneumatic cylinder moves back into its starting position, in which the traversing elements again cause a traversing movement of the yarn while it is moving from the winding device is wound up.
  • the lifting element extends at least across the width of the winding device. This ensures that the yarn is securely caught by the lifting element when it is activated. A movement of the lifting element in the width direction of the winding device (i.e. in the axial direction of an inserted bobbin) is therefore not necessary.
  • the lifting element can be rod-shaped, for example, and can be connected to a corresponding drive element, for example the pneumatic cylinder mentioned.
  • the yarn traversing device used has one or more traversing elements (e.g. in the form of a thread guide) which, if necessary, can be moved, pivoted or otherwise moved in such a way that they can be brought into a position in which they no longer come into contact with the yarn when the yarn is being unwound (from the winding device).
  • traversing elements e.g. in the form of a thread guide
  • wing traversing device This usually has two or more counter-rotating wing elements, which alternately come into contact with the yarn to be wound and finally move it back and forth accordingly when winding.
  • the unwinding position is a position in which the traversing element or elements can no longer come into contact with the yarn running between the winding device and the take-off device. If the wing elements mentioned are used, they would be rotated into a position in which the sections which come into contact with the yarn during winding are in an area which is outside the course of the yarn during unwinding.
  • the method according to the invention for removing an end section of a yarn on a spinning machine before a subsequent piecing process is finally distinguished according to the invention in that the end section of the yarn is unwound from the winding device after an interruption of the spinning process, and in that the end section is used as a component of the spinning station trained yarn end removal is detected, separated from the remaining yarn and then removed from the area of the spinning station, the yarn end removal being arranged at least partially between the outlet of the spinning device and the winding device.
  • the yarn can thus be processed individually at each spinning station before a service robot or corresponding operating personnel who carry out the piecing process have arrived at the spinning station.
  • the end of the yarn is located at a defined location, namely preferably in the area of the yarn end discharge, and can be fixed there as required (as mentioned above).
  • the yarn end discharge can be carried out according to one or more of the features already explained, although this is not absolutely necessary.
  • the conveying speeds of the delivery device, the take-off device for drawing off the yarn from the spinning device and the winding device are gradually reduced to a standstill before the end section of the yarn to be removed is unwound.
  • the reduction is advantageously carried out in such a way that the end of the yarn produced is after the reduction has ended between the exit of the spinning station and the winding device, preferably between the exit of the spinning station and the take-off device.
  • At least a section of the yarn end discharge preferably also extends into this area.
  • the yarn end resulting from the reduction in the delivery speeds is at a defined point and after the above units have stopped can be safely captured by the yarn end discharge, e.g. B. sucked in.
  • the yarn already wound on the winding device is fed backwards until the desired end section has been taken up by the yarn end discharge.
  • the end section is then cut off and disposed of (for example via a suction system of the spinning machine connected to the suction channel). If the yarn has been continuously pinched by corresponding take-off rollers of the take-off device after the yarn has been unwound and during the removal of the end section of the yarn, the yarn end produced by the removal of the yarn end section is finally also in the area of the take-off device.
  • This yarn end can now be gripped specifically by a service robot or an operator and fed to the subsequent piecing process.
  • a valve and / or a flow switch is assigned to the suction channel and that the air pressure within the suction channel is regulated with the aid of the valve and / or the flow switch.
  • the air flow prevailing in the flow channel can thus be individually adapted. An air flow is therefore preferably only generated if removal of a yarn end section is provided. In the normal spinning process, the valve is finally closed or the flow switch is adjusted accordingly until there is no more energy-consuming air flow within the suction channel.
  • the spinning station has a take-off device for drawing off the yarn from the spinning device, the yarn end being removed between the outlet of the spinning device and the take-off device.
  • the area mentioned is generally easily accessible, so that the end of the yarn can be reliably detected by a robot or an operator and fed to the piecing process, in which the end of the yarn is connected to the fiber material coming from the delivery device before the actual spinning process is continued.
  • the end section of the yarn to be discharged is unwound from a spool of the winding device, in that at least one drive of the spool is driven counter to the winding direction prevailing during the spinning process.
  • This enables a controlled unwinding process in which loop formation or other undesirable reduction in the yarn tension can be prevented.
  • the coil can be driven directly.
  • the winding device comprises a yarn traversing device and the yarn traversing device is assigned a yarn lifting device, the yarn being removed with the help of the yarn lifting device at least during the unwinding of the end section to be removed Yarn is brought out of the knitting area of the yarn traversing device.
  • the traversing device ensures that the yarn produced is deposited on the bobbin in a known manner during the spinning process, contact between the traversing device and the yarn during the unwinding process is undesirable in order to avoid damage to the yarn and / or traversing device.
  • This can be achieved in a simple manner by the yarn lifting device mentioned in that the yarn is moved in the area of the traversing device until it is no longer in contact with the traversing device.
  • Figure 1 shows a schematic side view of a spinning station 1 of an air spinning machine (as an example of a spinning machine according to the invention) during the spinning process, the air spinning machine generally comprising a plurality of spinning stations 1 arranged one behind the other perpendicular to the plane of the drawing and preferably of a similar design.
  • the air spinning machine has in the Figure 1 Example shown via a delivery device 7 designed as a drafting system, which is supplied with a fiber material 4, for example in the form of a doubled conveyor belt. Furthermore, the spinning station 1 shown has a spinning device 2 spaced apart from the delivery device 7 with an inlet 3 for the fiber material 4 and an internal air swirl chamber, not shown.
  • the fiber material 4 or at least some of the fibers of the fiber material 4 are provided with a rotation in a known manner within the air vortex chamber in order to produce the desired yarn 6.
  • the rotation is created by a targeted air flow in the area of a spindle tip, the air flow being generated by air nozzles opening tangentially into the air swirl chamber.
  • the spinning station 1 shown comprises a take-off device 12 formed by a pair of take-off rolls and a take-up device 8 connected downstream of the take-off roll pair and having an exchangeable bobbin 20 for winding up the yarn 6 drawn out of the spinning station 1 through the outlet 5.
  • the spinning machine can be equipped with a yarn monitoring unit 21, which predefined parameters of the yarn 6 (e.g. the yarn thickness, the yarn tenacity or other representative of the quality of the yarn 6) Parameters) and / or the presence of the yarn 6 is monitored at the corresponding position.
  • the yarn monitoring unit 21 preferably works without contact.
  • the device according to the invention does not necessarily have to have a drafting system, as is shown in Figure 1 is shown.
  • the extraction roller pair is also not absolutely necessary.
  • the spinning machine according to the invention can also be designed as a rotor spinning machine, the spinning device 2 in this case comprising a rotor and the delivery device instead of the drafting device comprising a feed roller and an opening roller.
  • the figures show a winding roller 22, via which the spool 20 can be set in rotation.
  • a yarn traversing device 16 e.g. in the form of a wing traverse
  • the conveying speeds of the delivery device 7, the take-off device 12 and the Winding device 8 gradually reduced. A reduction can also take place before the spinning machine is switched off.
  • the individual conveyor speeds should be such be throttled so that the spinning process is maintained as long as possible. An uncontrolled tearing of the yarn 6 can be avoided in this way. Rather, the aim of reducing the conveying speeds is to ensure that the stable spinning process comes to a standstill by falling below defined conveying speeds and that, from a certain point in time, no more yarn 6 is produced from the fiber material 4. At this point, the desired interruption of the yarn production finally occurs, in which the yarn 6 detaches from the fiber material 4 without the application of a separate force. This can be achieved, for example, by reducing the conveying speed of the delivery device 7 to such an extent that it no longer delivers a sufficient amount of fiber material 4 in order to form a yarn 6 therefrom.
  • the pair of draw-off rollers can be operated for a short period of time until the end of the yarn 6 that has come to a definite position after the delivery device 7, the take-off device 12 and the winding device 8 have come to a standstill, as shown in FIG Figure 2 is shown.
  • the take-off device 12 or the winding device 8 In order to be able to stop the take-off device 12 or the winding device 8 at the right time, it may be advisable to equip the spinning machine with a sensor which, for example, can be integrated in the yarn monitoring unit 21 or can also be positioned at a separate location.
  • the sensor is designed to be able to detect the end of the yarn 6.
  • the take-off device 12 and the winding device 8 can be stopped either immediately or with a certain time delay with the aid of the appropriate control and / or regulating unit, so that the end of the yarn 6 finally lies between the Output 5 of the spinning station 1 and the take-off device 12 is located.
  • the spinning station 1 now has its own yarn end discharge 9.
  • this has a suction channel 11, which is connected, for example, via a flow switch 15 or else directly (not shown) to a section of a suction system 23 of the spinning machine.
  • the flow switch 15 can also be coupled to the suction device 13 of the delivery device 7, as shown in the figures. By switching the flow switch 15, it is finally possible to apply suction to the suction device 13 of the delivery device 7 in the normal spinning process, while in the course of the removal of an end section of the yarn 6 described below (e.g.
  • the suction channel 11 with the Suction system 23 is connected - with simultaneous deactivation of the suction device 13 of the delivery device 7. Additionally or alternatively, it is also possible to equip the suction channel 11 with a valve 14, with the aid of which a regulation of the air volume flow within the suction channel 11 is also possible.
  • the suction channel 11 should be pressurized as soon as the spinning process has ended and the yarn end is in a position as shown in FIG Figure 2 is shown.
  • the pair of rollers of the extraction device 12 and the bobbin 20 is driven counter to the direction of rotation prevailing in the spinning process (see rotation arrows), so that the yarn 6 is unwound again from the bobbin 20 (the take-off device 12 and the bobbin winding device 8 preferably have individual drives for this purpose in order to implement the reverse direction of rotation mentioned).
  • a yarn lifting device 17 to the yarn 6 in this area, which, for example, has a lifting element 18 extending over the width of the bobbin 20 and a pneumatic cylinder 19 connected to it features. How out Figure 2 can be seen, the yarn 6 is finally moved so far against the yarn traversing device 16 until the yarn 6 can no longer get into the effective area thereof (see Figures 2 to 4 ).
  • the yarn 6 is now unwound from the bobbin 20 until the end section of the yarn 6 which is unsuitable for a subsequent piecing process is located within the suction channel 11.
  • the length of the yarn 6 can correspond, for example, to a predetermined length, which is determined using a sensor or the number of revolutions of the bobbin 20 or the rollers of the take-off device 12. If, as described above, the yarn production is interrupted by throttling the delivery speeds, it is advisable to remove at least the section that was produced during this throttling, since its quality usually does not meet the requirements.
  • the yarn end discharge 9 is deactivated again, i. H. the valve 14 is closed, the discharge switch is adjusted in favor of the suction device 13 and / or the air flow within the suction channel 11 is interrupted by deactivating the suction system 23.

  • one of the two traversing elements 24 alternately comes into contact with the yarn and finally moves it (in relation to FIG Figure 6 ) from right to left (and vice versa) to ensure the desired traversing, ie the lateral movement of the yarn 6, which is additionally guided in its movement via a deflection element 25.
  • the traversing elements 24 are brought into a position such as that of the essentially horizontally extending traversing element 24 in Figure 6 occupies. Since contact between the yarn 6 and the traversing elements 24 is excluded in this position, there is no mutual impairment during the desired unwinding. As soon as yarn 6 is finally to be wound onto the bobbin 20 again, the traversing elements 24 rotate again in the opposite directions mentioned and again effect the desired traversing of the yarn 6.
