Definitions

  • centrifugal spinning is a long-known spinning process. Centrifuge spinning basically distinguishes between two different types of spinning, the so-called single-stage spinning and the so-called two-stage spinning.
  • both types of spinning material is first a reference material, either a stocked in a sliver canister sliver or roving available roving in a drafting, according to the desired yarn count, warped and conveyed via an axially slidably mounted yarn guide tube in a rotating at high speed centrifuge spinning element.
  • the emerging from the mouth of the yarn guide tube template material lays out, forming a yarn leg, to the centrifuge inner wall and is taken away by this. That is, the fiber material is rotated by the rotation of the rotating leg of the centrifuge spinning element.
  • the resulting by the rotation pitch thread is by the thread guide tube, the changierbar and axially displaceable is stored, deposited on the centrifuge inner wall and forms there a package, a so-called spinner cake.
  • the centrifuge speed and the delivery speed of the original material are coordinated so that the deposited as a spun cake thread already has its final rotation and wrapped in a subsequent operation on one, for example, on the thread guide tube or introduced from below into the centrifuge spinning element Umspulhülse can be.
  • the resulting in this rewinding spinning cops are later rewound by means of a downstream in the production process winding machine to large-volume cheeses.
  • a centrifugal spinning apparatus which has a tubular, supported in magnetic bearings centrifugal spinning element, which has a centrally disposed electromagnetic centrifuge drive.
  • Such designed centrifugal spinning devices are easily accessible both from above and from below, so that a rewinding either, as shown in DE 42 08 039 A1, can be introduced from below into the centrifuge spinning element or, as for example in DE 195 23 835 A1 described, slidably disposed on the yarn guide tube is and then introduced from above into the centrifugal spinning element.
  • tubular spinning centrifuges as also described in EP 0 931 864 A, are easily accessible, they have the considerable disadvantage that they have a relatively high energy consumption due to their design. That is, the position of the drive, whose rotor comprises the tubular centrifuge spinning element in the region of the largest diameter, leads to a relatively unfavorable energy use.
  • a much more favorable energy use results when a so-called pot centrifuge is used, that is, when a centrifugal spinning element is used which has a neck-like projection on which the electromagnetic drive of the spinning centrifuge is installed.
  • a spinning centrifuge constructed in this way is known, for example, from WO-98 / 11,284.
  • the rewinding tube is inserted into the centrifuge spinning element through a centrifuge opening opposite the centrifuge neck and the finished spinning cop is removed through the same centrifuge opening.
  • the filing of the spun cake from bottom to top That is, at the end of the spinning process, the rewinding is initiated by the rewinding when the Thread guide tube has reached its upper end position in the vicinity of the spinning centrifuge bottom.
  • the package is in this case from top to bottom, that is, starting at the sleeve tip, wound on the rewinding.
  • the spinning cops manufactured have proved to be disadvantageous in these known centrifugal spinning apparatus since the winding direction of such spinning cops differs from spinning cops which have been produced on ring spinning machines.
  • the present invention seeks to provide a centrifugal spinning device, which does not have the aforementioned disadvantages and in particular the production of spinning clots, which hardly differ from ring spinning heads.
  • the spinning device With the spinning device according to the invention, it has been possible in a simple manner to avoid the disadvantages of the known spinning devices. That is, the spinning cops present after the rewinding operation are constructed, for example, like spinning cops which have been manufactured on a ring spinning machine and can therefore be processed easily with the conventional winding technology. Furthermore, in the inventively designed centrifugal spinning the last deposited yarn layer of the spun cake remains accessible at all times, so that if necessary, for example, after a yarn breakage during the spinning process or a winding break during Umspulvorganges, at any time an external introduction of Umspulvorganges is possible.
  • the resulting in such an external introduction of the rewinding thread subsystem is relatively short, so that the resulting Spinnkops is then on the winder usually without rest can be unwound.
  • the resulting after an external initiation of the rewinding spinning cop can also be easily removed from the centrifuge spinning element.
  • a sensor device which monitors the current template material.
  • the sensor device which is preferably positioned between the drafting system and the thread guide tube, is connected via a signal line to a corresponding control device, preferably a workstation computer, so that, in the event of a thread break, it is ensured that, for example, the further supply of fiber material into the centrifuge spinning element is interrupted Umspulvorgang is initiated.
  • the sensor device can also, as described in claim 3, be arranged below the centrifuge spinning element and then monitors the rotating yarn leg. Also in this case, the sensor device is connected via a signal line to the workstation computer, which ensures that, in the event of a yarn breakage, the supply of fiber material into the centrifuge spinning element is stopped and a rewinding process is initiated.
  • a thread release device is present, which is defined on the winding cone of the package can be adjusted and thereby the rewinding of the rotating with the centrifuge package on the on the thread guide tube arranged, in the rewinding available Umspulhülse starts.
  • the thread release device is used both after a thread break during the spinning process as well as after a winding break during the rewinding. In both cases, the thread release device is employed on the winding cone of the rotating with the spinning centrifuge package and thus initiated a rewinding.
  • the doffing of the manufactured spinning cop is effected by the centrifuge neck opposite the centrifuge neck (claim 5).
  • the neck region of the centrifugal spinning element can be kept relatively small, which has a positive effect in particular on the energy consumption of the spinning device.
  • centrifuge spinning device generally designated by the reference numeral 1, of a centrifuge spinning machine (not shown) is shown schematically.
  • Such centrifuge spinning devices 1 equipped with a so-called pot centrifuge are known in principle and are described in relative detail, for example, in WO-98 / 11,284.
  • centrifugal spinning devices 1 preferably have a centrifuge spinning element 3 rotatably mounted in a spinning housing 2, which is supported in bearings 4 and driven by an electromagnetic drive 5 single motor.
  • the bearings 4 are preferably formed as a magnetic bearing, for example as a permanent magnet bearing.
  • the centrifuge spinning device 1 further has a thread guide tube 7 which can be inserted into the centrifuge spinning element 3.
  • the drive tube 7 is connected to a drive 8 indicated only schematically, which gives the thread guide tube 7 a traversing movement and axially displaces the thread guide tube 7 simultaneously with respect to the centrifuge spinning element 3.
  • a rewinding 9 is slidably mounted on the yarn guide tube 7, for example, on the hollow piston rod of the yarn guide tube 7 surrounding pneumatic cylinder 10, a rewinding 9 is slidably mounted on the yarn guide tube 7, for example, on the hollow piston rod of the yarn guide tube 7 surrounding pneumatic cylinder 10, a rewinding 9 is slidably mounted.
  • the pneumatic cylinder 10 is connected via a corresponding pneumatic line, in which a valve, for example, a 2/2-way valve 22 is turned on, connected to a (not shown) compressed air source.
  • the valve 22 is connected via a control line 21 to the workstation computer 19.
  • the rewinding 9 is fixed during the regular spinning process on the pneumatic cylinder 10 with respect to the yarn guide tube 7 in a rest position 11 and can be, for example, to initiate the Umspulvorganges, relocated in a Umspulgna 12 indicated by dashed lines.
  • the centrifuge spinning device 1 has a sensor device 13 for detecting a yarn breakage.
  • the sensor device 13 which monitors the current master material 18, is positioned in a preferred embodiment below the drafting device 6 and connected via a signal line 20 to a spinning station own control device 19.
  • the sensor device 13A which is likewise connected to the workstation computer via a signal line 20A, is designed, for example, as a light scanner and monitors the circulation of the rotating yarn leg 28.
  • a thread release element 14 is also provided.
  • the thread release element 14 in this case has an engagable to the winding cone 29 of the package 15 cutting edge 16 and a cutting edge 16 in the axial direction encompassing Fadenleitkontur 17 which are parallel to the centrifuge inner wall 25 via a drive 23 displaced.
  • the drive 23 of the thread release element 14 is connected via a control line 30 to the spinning station-own control device 19, the so-called workstation computer, and can be controlled via this defined.
  • a sliver-delay device for example a drafting device 6, arranged above the centrifuge spinning element 3, is fed with a sliver from a sliver (not shown) or with a supply material 18 from a flyer bobbin (also not shown).
  • the template material 18, for example, a roving is warped according to the desired fineness and passed over the yarn guide tube 7 in the centrifuge spinning element 3, where it is to form a rotating yarn leg 28 to the inner wall 25 of the circulating Centrifuge spinning element 3 applies and thereby receives a rotation. That is, the resulting from this rotation thread is positioned by the yarn guide tube 7 on the inner wall 25 of the centrifugal spinning element 3, that a defined package, a so-called spin cake 15 is formed.
  • the yarn guide tube 7 is oscillated up and down by the drive 8 and simultaneously lowered continuously in the direction of the centrifuge opening 27.
  • the spun yarn is thereby temporarily stored in the manner of a so-called Kopswicklung on the inner wall 25 of the centrifuge spinning element 3.
  • a rewinding operation is initiated. That is, the yarn guide tube 7 is first by the drive 8 in the next top dead center of its traverse stroke moved and then the rewinding 6 displaced by the pneumatic cylinder 10 from a rest position 11 in a rewinding position 12 in the region of the rotating yarn leg 28.
  • the control device 19 which interrupts the further supply of roving 18.
  • the spinning cop resulting from the rewinding is then doffed via the centrifuge opening 27 and fed, for example, to a downstream winding machine.
  • the directional control valve 22 then ensures that the pneumatic cylinder 10 moves the rewinding sleeve 9 from its rest position 11 into its rewinding position 12, while the drive 23 retracts the thread release device 14 parallel to the inner wall 25 into the centrifuge spinning element 3.
  • the thread release device 14 lies with its cutting edge 16 against the winding cone 29 of the package 15.
  • Garn emotions 15 a thread loop out, which winds around the rewinding 9 and thus initiates the rewinding.
  • the cutting edge 16 of the thread release device 14 engages close to the inner wall 25 of the centrifuge spinning element 3, it is not always possible to avoid that some winding layers of the spinning cake 15 are arranged below the cutting edge 16. These winding layers are raised during the Umwickelvorganges by the Fadenleitkontur 17 in the direction of the rewinding 9 and passed to this. In this way it is avoided that the thread release element 14 is wound.
  • the yarn package 15 originally deposited on the inner wall 25 of the centrifuge spinning element 3 is rewound onto the rewinding tube 9 prepared in the rewinding position 12, thereby forming a spinning cop.
  • the spinning cop (not shown) is then removed through the centrifuge opening 27 and transferred for further processing to a downstream textile machine, preferably a winding machine.
  • the thread release device 14 is also used when it has come to a winding break during Umspulvorganges. That is, if only a part of the package 15 could be wrapped on the rewinding 9.
