Definitions

  • the invention relates to a centrifuge spinning method according to the preamble of claim 1, with which yarn of a classic character can be spun, and a device therefor.
  • a completely twisted yarn is placed in a centrifuge, which creates the problem of removing the winding from the centrifuge.
  • a mandrel is inserted into the still rotating centrifuge, which leads to a rewinding process, so that at the end of the operation the yarn is on the mandrel, from which it has to be rewound in a further step to a salable presentation.
  • a problem with this method is a yarn break, because the yarn end has to be found in the rotating centrifuge, which can only be solved with considerable effort.
  • GB-A-1 048 259 has disclosed a centrifuge spinning method and a centrifuge spinning device for spinning a yarn of a classic character, the centrifuge being rotatably arranged within a closed housing and air being blown out of the centrifuge.
  • the invention has for its object to provide a centrifuge spinning process of the type mentioned, which works with a low capital and energy input.
  • the purpose of the invention is to produce a ring yarn-like yarn of high quality with lower costs and less energy input than is possible with ring and rotor spindles of the prior art.
  • the object is achieved according to the invention by a centrifugal spinning method for spinning a yarn of classic character, by either spinning and removing a fully twisted yarn in a stage or a partially twisted yarn in a centrifuge in a first stage and the same in a second stage during the partially twisted yarn Remove the remaining rotations by winding, using the centrifuge, a drafting device, a piecing element and a thread guide tube that changes into the centrifuge; according to the invention, the centrifuge rotates in a room with negative pressure within the centrifuge but the normal air pressure and in the centrifuge is spun under normal air pressure, the vacuum being set so that essentially only the bearing friction of the centrifuge occurs when the centrifuge rotates and the air friction of the outer wall of the centrifuge is largely suppressed.
  • the space between the preferably bottle-shaped centrifuge and a surrounding housing is sealed from the environment and subjected to negative pressure.
  • the vacuum can advantageously be continuously pumped in to compensate for leaks.
  • the seal is located at a point that is at a short distance from the axis of rotation of the centrifuge, that is, preferably at its neck.
  • a vacuum centrifuge spinning device is characterized in that the centrifuge is rotatably arranged within a housing and the interior between the centrifuge and the housing can be subjected to negative pressure, but within the centrifuge there is normal air pressure, the negative pressure being adjustable so that when rotating in essentially only the bearing friction of the centrifuge occurs, but the air friction with respect to the housing is largely suppressed.
  • the centrifuge is advantageously bottle-like or bottle-shaped with a central, narrow neck.
  • the housing and / or centrifuge can consist of at least two parts which can be moved apart, one part of the centrifuge being rotatably mounted axially in one part of the housing and the other part axially in the other part of the housing. Further advantageous refinements of the invention are contained in the dependent subclaims.
  • the vacuum centrifuge spinning process and the vacuum centrifuge spinning device have the salient advantage that the specific capital and energy requirements, based on a yarn of the same strength and fineness, is lower than that of the known ring and rotor spinning.
  • a sufficiently simple spinning device can be constructed with the vacuum centrifuge spinning device, the speed of rotation being determined only by the strength of the centrifuge, without the energy expenditure for driving the device becoming too high.
  • speeds of up to 80,000 rpm and more can be achieved, so that the drafting system can be operated at much higher delivery speeds. It is therefore possible to spin with a specifically lower energy expenditure than is possible with ring and rotor spinning devices.
  • FIG. 1 shows a basic illustration of an example of a vacuum centrifuge spinning device 5 for carrying out the method.
  • the emerging sliver 13 arrives from a drafting device 1 into a piecing member 2, with which spinning is automatically carried out.
  • the piecing or swirl member 2 guides the yarn that forms in a thread guide tube 3 into a thread guide tube 4, which changes in the centrifuge 6 in the direction of the double arrow.
  • the thread guide tube With single-stage centrifugal spinning, the thread guide tube lays the yarn with a wild cross winding, with stage spinning in two stages, however, in a kind of parallel winding.
  • the centrifuge 6 is in a housing 5 ', which can in principle be opened to remove the centrifuge, which is indicated by the dividing lines 73, 73', by means of a bearing 10, freely hanging or free-standing, around a bottle-like neck 62 of the centrifuge 6 stored.
  • the neck 62 of the centrifuge 6 is hollow and at the same time forms the axis of rotation of the centrifuge 6 and the access for the thread guide tube 4 into the centrifuge 6, which can therefore preferably be described as bottle-shaped.
  • the centrifuge neck 62 has a diameter d h which, relative to the diameter d z of the centrifuge 6, is relatively small.
  • the centrifuge 6 is driven by means of a whorl, which is indicated by the curved reference arrow 12.
  • the centrifuge 6 is filled when the inner diameter of the yarn winding 9 is approximately 40 mm. In pure centrifugal spinning, the speed is now reduced to about 1/10, the negative pressure is eliminated and the yarn package 9 is removed from the housing by opening the housing, or the yarn can be spooled out of the housing without opening the housing or the centrifuge becomes.
  • spinning can be carried out directly from the jug, making good use of the capital tied up in a high drafting system.
  • the transport of the tape to the drafting system is facilitated in that a false wire element is arranged in front of the drafting system.
  • a sliver divider can be arranged between the false wire element and the drafting system, which supplies both drafting systems.
  • FIG. 2 shows the spinning elements located between two drafting devices 1, 1 'and can 14, namely false twist elements 15 and sliver dividers 16.
  • the former gives the belt 13 incorrect rotations, which enables transport to be carried out without distortion.
  • the latter distributes the fuse emerging from the false wire element 15 over two drafting devices 1, 1 '.
  • FIG. 3 shows the drafting and piecing element 2 in section.
  • the outlet rollers 17 of the drafting unit 1 are opposite the intake duct 18 of the piecing element 2, two tangential ducts 19, 19 ′ being acted upon by air being located therein;
  • an auxiliary suction duct 20 can be arranged in the region of the mouth of the suction duct 18.
  • the diameter of the intake duct 18 is preferably less than 3 mm.
  • Compressed air p ü enters the thread guide tube 3 via the channels 19, 19 'and forms a vortex, in the center of which there is negative pressure. As a result, a fiber ribbon is sucked in and twisted, which is supported by the auxiliary suction 20.
  • the thread guide tube 3 preferably has a diameter of less than 6 mm and opens into the same at the top dead center of the thread guide tube 4.
  • the drafting system axis 72 and the axis of the thread guide tube are perpendicular in alignment.
  • the drafting system axis 72 can, however, be inclined continuously up to an angle, preferably 45 degrees, against the axis of the thread guide tube; the fulcrum corresponds to the center of the lower roller of the drafting system. This allows the yarn character to be set within limits.
  • a optimal propagation of the spinning tension up to the clamping line of the drafting system is achieved, whereby a tendon-shaped deposit of the yarn in the centrifuge is avoided.
  • FIGS 4a to 4c show the process steps in pure centrifugal spinning.
  • the centrifuge 6 consists of two centrifuge parts, namely a centrifuge upper part 21 and a centrifuge lower part 22, inside is the yarn winding 9.
  • a doffer 23 is assigned, which consists of a holding part 42, which can be suitably held on the machine device and the one rotatable Spike 67 carries, on which a sleeve 28 is rotatably arranged, which is able to carry a yarn package 9.
  • the centrifuge 6 is moved apart while maintaining a residual speed of 1/10 of the operating speed, so that the doffer 23 can be inserted into the yarn package 9.
  • the speed is set to zero, as a result of which the yarn winding 9 shrinks onto the sleeve 28.
  • the yarn winding 9 is removed and can be rewound overhead from the sleeve 28, which is indicated in FIG. 4c by the pulling arrow 24 that pulls the thread 8.
  • the centrifuge 6 is closed and continues to spin.
  • the yarn winding 9 according to FIG. 4d is transferred to an auxiliary centrifuge 25 with a central mandrel 26. After delivery at a standstill, the auxiliary centrifuge 25 is brought to approximately 10,000 rpm. According to FIG. 4e, the yarn 8 can be rewound from the inside outwards with additional rotation. As a result, the yarn is given a few twists per meter if it is unwound at over 2,000 m / min. If the entire process is considered, there is again a step spinning process.
  • the yarn can be pulled out of the centrifuge with continued rotation and wound onto a spool which is in the immediate vicinity of the centrifuge, as shown in FIG. 5. It has proven to be advantageous to spin the yarn in two-stage centrifugal spinning give up at least 90 percent of the rotations, preferably 95%, in the first stage and the rest of the rotations in the second stage.
  • a vacuum centrifuge spinning device 5 which is similar to that in FIG. 1, there is a cutting and clamping device 27 and a winding device 29.
  • the thread guide tube 4 reaches its top dead center .
  • the yarn 8 is fixed by the cutting and clamping device 27 and thrown and wound onto the winding device 29 by an auxiliary roller 30, whereupon the work cycle is repeated.
  • the cutting and clamping device 27 can be moved in the direction of the double arrows in FIG. 5 and ensures a clean separation of the yarn.
  • FIG. 6 shows a preferred embodiment of a vacuum centrifuge spinning device, preferably for pure centrifugal spinning. Centrifuges for pure centrifuge spinning have a capacity of approx. 100 grams of yarn.
  • the vacuum centrifuge spinning device consists of a two-part housing 31, within which a bottle-shaped centrifuge 35 is arranged; in the space 40 between the housing 31 and the centrifuge 35 there is negative pressure p u ; inside the centrifuge 35 there is normal pressure p n .
  • the centrifuge can consist of at least two parts which are telescopically inserted into one another or are somewhat conical in shape, the expansion behavior of the centrifuge parts under centrifugal force being matched to one another both by a suitable choice of material and by suitable shaping of the centrifuge parts such that when the two are inserted into one another when rotating Centrifuge parts results in a hermetically sealed centrifuge.
  • the parts can be pressed together by axially acting compressed air.
  • One centrifuge part can be rotatably mounted in one part of the housing, the other in the other part of the housing, a drive motor being assigned to one of the centrifuge parts.
  • the centrifuge is run up to an intermediate speed which is chosen so high that the two centrifuge parts are tightened airtightly against one another due to different expansions, the inner centrifuge part being under the Centrifugal forces expands so that the centrifuge forms an airtight system and the space between the housing and the centrifuge is now evacuated to a vacuum p u ; then the centrifuge speed is increased until it reaches its operating speed.
  • the bracing is thus chosen so large that the axial forces caused by the vacuum subsequently applied are absorbed.
  • the housing 31 and the centrifuge 35 each consist of two parts 32, 33 and 36, 37, the upper, outer centrifuge part 36 being mounted in the upper housing part 32 by means of an axial fixed bearing 34, 34 '.
  • An axial seal 38 seals the upper centrifuge part 36 or the centrifuge neck 69 from the housing 31 in an airtight manner.
  • the lower, inner centrifuge part 37 which receives the yarn winding, is mounted in the lower housing part 33 by means of an axial floating bearing 39, 39 ', which can be moved apart in relation to the upper housing part 32 and the upper centrifuge part 36.
  • the lower housing part 33 receives an electric motor 41, which drives the lower centrifuge part 37.
  • the bearings only run under the load of the gyroscopic forces; the entire system is spring-loaded, so that in principle there is a free gyroscope.
  • the centrifuge parts 36 and 37 are nested and hermetically seal when rotating.
  • an overpressure p u can be applied axially from the outside to the lower housing part 33, which pushes the parts that are movable relative to one another.
  • the overpressure is set to zero; the materials and dimensions of the centrifuge parts 36, 37 are matched to one another in such a way that a centrifugal force between the jacket walls of the centrifuge parts 36, 37 results in a non-positive air-tight connection.
  • the centrifuge 35 has reached a minimum speed and the centrifuge parts 36, 37 are pushed into one another, the space 40 is evacuated; the centrifuge 35 then reaches its operating speed within the housing 31.
  • FIG. 7 shows a preferred embodiment of a vacuum centrifuge spinning device for two-stage step spinning, which deposits the yarn in parallel windings and normally has a capacity of at least 50 g of yarn.
  • a centrifuge 45 with only one axis 62, which - similar to the centrifuge 35 in FIG. 6 - consists of two centrifuge parts 46 and 47, the upper, outer centrifuge part 46 or the centrifuge neck 70 inside the housing 43 by means of a Fixed bearing 68, 68 'rotatably supported and sealed airtight to the outside with a seal 38.
  • An electric motor 41 ' is in turn an integral part of the housing 43 and the upper centrifuge part 46 and thus advantageously arranged here in a vacuum.
  • the housing 43 is swinging, so that the centrifuge 45 is gimbaled. At the opposite end, the housing 43 can be closed in an airtight manner by means of a movable cover 44, which is indicated by the double arrow.
  • the inner centrifuge part 47 is cup-shaped in the centrifuge part 46; the space 48 between the housing 43, cover 44 and centrifuge 45 can in turn be evacuated.
  • This vacuum centrifuge spinning device into which one spins in and out, only needs to be opened if the remnants of a yarn package have to be removed if the thread breaks.
  • the cover 44 is moved away and the housing 43 is opened.
  • a plunger 49 can suck on the bottom of the lower or inner partial centrifuge 47 by means of negative pressure pu and pull it out of the upper or outer centrifuge part 46.
  • the punch 49 is designed to be rotatable, the yarn package can also be removed in an orderly manner, since it remains on the wall of the centrifuge part 47 due to the centrifugal force. In the case of pure centrifugal spinning, on the other hand, spinning can continue despite thread break.
  • the procedure can be taken jointly so that a centrifuge part hangs on each housing part and the non-positive connection of the centrifuge parts can be established by applying an overpressure.
  • the overpressure is set to zero and, with sufficient speed, the space between the housing and the centrifuge is evacuated to practically vacuum. No forces act on the bearings of the centrifuge because one of the bearings is designed as a fixed bearing, the other as a floating bearing; the centrifuge runs gimballed.
  • FIG. 8 shows a further embodiment of a vacuum centrifuge spinning device.
  • a centrifuge 53 is arranged, which consists of two centrifuge parts 54, 55; the space 56 between the housing 50 and the centrifuge 53 can be practically evacuated to a vacuum.
  • the upper, outer centrifuge part 54 in the upper housing part 51 of the housing 50 has a bearing 57 which is mounted elastically for gimbal mounting in a molded rubber 58 and is sealed airtightly against the molded rubber 58 by means of a seal 59 against the centrifuge neck 71.
  • the upper housing part 51 also has a braking device 60.
  • the lower, inner centrifuge part 55 is suitably supported and driven at its lower, not shown end; it can be removed in the axial direction - similar to the centrifuges 35, 45 of FIGS. 6, 7 - from the upper centrifuge part 54, so that a yarn package or yarn remnants can be removed from the inner centrifuge part 55 during step spinning.
  • a force and / or positive connection between the centrifuge parts 54, 55 is achieved in that the outermost edges or ends of the centrifuge parts fit conically into one another or are provided with threads 61, 61 'or bayonet locks, so that the ends of the centrifuge parts 54, 55 according to Figure 8 interlock.
  • the centrifuge part 54 is prevented from rotating by the brake 60, the lower centrifuge part 55 being moved axially and with rotation against the upper centrifuge part 54, so that the centrifuge 53 is closed .
  • the opening of the centrifuge 53 takes place in reverse order, the same being stopped and the upper centrifuge part 54 being blocked by means of the brake 60, then the motor runs briefly in the opposite direction, so that the centrifuge parts 54, 55 separate; the yarn package inside shrinks.
  • the lower partial centrifuge 55 is rotated again separately by means of a motor, as a result of which the yarn package opens and becomes stiff, so that a doffer can be inserted and the yarn can be removed.
  • one of the housing parts of the housing can have a braking device for braking and stopping the assigned centrifuge part relative to the held, relatively movable centrifuge part of the centrifuge have, wherein this centrifuge part is preferably rotatably mounted within the associated housing part by means of a fixed bearing.

  • the vacuum centrifugal spinning process and the vacuum centrifugal spinning device are particularly suitable for producing yarns of a classic character, it being possible to spin with a specifically lower energy and thus capital expenditure than is possible with ring and rotor spinning devices of the prior art.
  • the specific energy and capital requirement, based on a yarn of the same strength and fineness, is lower than that of ring and rotor spiders of the prior art.
