Definitions

  • the invention relates to a machine for processing synthetic Threads with a large number of processing points with supply spools, of which at least one thread runs off, with winding devices, each with a driven drive roller with a vertical one Axis and an axis parallel to the drive roller, in their distance to Drivable roller changeable, applying a coil to the driving roller Have spool shaft, and with the thread in short strokes along the coil-laying installation devices, wherein between the Winding devices and the laying devices for building the Winding a relative movement takes place.
  • a machine with such a device is from the DE 31 22 385 A known. It allows the production of coils Parallel winding in which the winding layers are cylindrical and shorten with increasing diameter.
  • the relative The stroke movement between the spool and the laying device is carried out here Up and down guidance of the laying device achieved. This changed the thread length between the feed point of the thread Laying device and its point of contact on the spool. This leads to an increase in the length of the thread Tension in the thread when the thread length decreases a decrease in the thread tension and can be particularly who are sensitive to different tensile loads, too Lead to quality impairments.
  • the invention was based on the task of a machine variable thread lengths between the Avoid the supply spool and the winding spool or so far to mitigate that they have no adverse effect on the Quality of the thread.
  • the movable up and down Winding devices on a common, up-and-down-led Store bank.
  • the vertical devices Guide and to transfer the rotary drive for the winding devices and to control this vertical movement are e.g. of bobbins on roving machines known and can in this or a similar shape.
  • the lifting height this bank decreases with increasing diameter of all coils will.
  • this batch change is not desired or it is preferred to break a thread at one of the workplaces the wrapping process on a newly attached, to continue empty sleeve.
  • a second embodiment according to claim 4 that the Up-and-down movement of the winding devices remains unchanged and the laying devices individually and depending on the increase of the diameter of the coil to which they are assigned, in the sense be moved so that they are the predetermined by the laying device Reduce the lifting height with increasing diameter of the coil. In this way, coils with conical ends are also produced. This is an up-and-down movement with less Amplitude and frequency that are not detrimental to the Quality of the thread affects.
  • the facilities for moving the laying devices can be designed according to claim 5, such as this from DE 26 51 816 C is known.
  • This embodiment offers the Advantage that the individual coils are wound independently be removed at any time and through an empty sleeve can be replaced at the wrapping again with the largest Beginning stroke of laying begins.
  • the increase in coil diameter and the changing altitude of the winding devices detected by sensors and via a control device the laying devices are motorized.
  • the laying devices have a device that the gradually reduced laying stroke over almost the entire length the sleeve a short-wave back and forth laying over an essential smaller width overlaid.
  • Such devices are known for example from DE 26 51 816 C and DE 31 22 385 A.
  • Claim 6 is the facility in itself from the DE 31 22 385 A known manner.
  • the round, eccentrically rotatably mounted on the circumference and by the disc driven by a groove running on the circumference of the thread DE 26 51 816 C lays the thread in an approximately sinusoidal Wave around the circumference of the coil.
  • the amplitude of this wave and so that the width of the laying can be chosen by choosing the diameter this disc can be changed. However, this also means the speed of the disc and hence the frequency of the wave proportional is changed, a maximum crossing angle of the threads not be exceeded.
  • the machine has no delivery plant, the take-off speed of the thread and its throughput speed through the machine then through the Speed or peripheral speed of the drive roller determined.
  • the throughput speed the thread is generally chosen to be constant.
  • the drive of the coils by means of a drive roller offers the advantage that the thread speed regardless of the increase in Wind diameter remains the same. Since that too Thread length between an inflow point and an upwind point Thread as a result of the essentially stationary according to the invention The arrangement of the laying devices remains the same Device according to the invention very good conditions for Use of treatment facilities even for threads with the highest Requirements for constant tension in the machining area.
  • the device according to the invention lends itself between the supply spool and the winding devices a thread treatment device interpose.
  • this from an adjustable thread brake, by means of which the thread tension in the area of winding onto the bobbin of those being removed from the supply spool can.
  • Offers further options for editing the thread a thread feed mechanism in the form of a pair of rollers or one Godet device. By setting the delivery speed accordingly this thread feeder in relation to Pull-off speed of the winding device can then already a defined delay or - with the addition of a thread heating device - a defined shrinkage of the thread respectively.
  • the thread treatment device can be in one Crimping, swirling, heating or splitting device or their sensible combination.
  • a Splitting device will be several, together by the supply spool running threads separated from each other and each for itself wound on a spool. This facility sets exactly the same Take-off speed at all, the split individual threads upwinding upwind devices ahead by the circumferential drive of the coils, regardless of where appropriate only slightly different diameters is guaranteed.
  • Fig. 1 is a work station 1 of the machine according to the invention shown for processing synthetic threads. It goes without saying that the machine has a large number of juxtaposed has similar jobs. Not closer to that The illustrated machine frame is at every work station a supply spool 2 with a large diameter and straight flanks held stationary, the thread on cops without issuing one Rotation should be rewound. In extension of the axis of the Feed bobbin 2, a thread guide 3 is arranged.
  • the machine also has a coil bank 4, which according to the Arrow A can be moved up and down.
  • This coil bank which can be moved up and down, has a total of 5 designated lifting device.
  • Two disks 18 and 19 are also free on the frame of the machine rotatably mounted, which have a thread groove on their circumference and one of which (19) laterally with one outside its axis of rotation lying thread guide pin 20 is provided.
  • the radial position this thread guide pin 20 to the axis of rotation of the disc 19 is on adjustable way not shown here.
  • These discs 18 and 19 form a laying device designated overall by 21.
  • the friction roller 6 displaces the bobbin tube 14 or the coil 16 in rotation. This turns the treating thread 22 attached to the bobbin tube 14 from the Supply spool 2 is pulled through the thread guide 3 and on the coil 16 wound. It runs through the thread groove of the Disk 19 in the thread groove of the disk 18 and offset the two This causes the discs to rotate. From the thread groove of the disc 18 the thread 22 runs over the thread guide pin 20 to the winding 15 of the Coil 16.
  • the thread guide pin is displaced 20 and moves the point of the thread to the winding 15 by twice the amount of its eccentricity to the axis of rotation of the Disc in the direction of the axis of the coil 16.
  • the lifting height of the coil bank 4 is based on a maximum value with simultaneous start of wrapping at all workplaces a machine gradually reduced, so that cylindrical thread layers decreasing length are formed and coils with tapered Embankments arise. After all the coils of the machine at the same time have reached the extent indicated by dashed lines, the Machine stopped, the full bobbins exchanged for empty tubes and the next trigger wound.
  • thread guide 3 and the laying device 21 as a dash-dotted frame indicated thread treatment device 23 may be arranged.
  • she consists in the simplest form according to FIG. 1a of an adjustable Thread tensioning device, which here in its simplest form as Pin thread brake 24 is shown. Both of them from thread 22 wrapped pins 25, 26 are around a parallel to them, on the axis between them can be swiveled and locked. With such a thread brake, the thread tension between the thread brake 24 and the winding point of the thread 22 on the spool and thus the hardness of the spool 16 or the elasticity of the thread can be influenced.
  • this Delivery roller pair 27 has the advantage that the thread tension regardless of the possibly changing or fluctuating Pull-off force set from the supply spool 2 and possibly higher or less can be selected than this pull-off force.
  • the delivery roller pair 27 in the thread run one Galetten / laying roller combination 28 is subordinated, there is the possibility to stretch the thread 22 cold or if - how indicated by dashed lines - a heating device 29 provided will stretch or shrink the thread hot.
  • the thread treatment device 23 also other or further devices such as a thread swirling nozzle 30, a false twist device, not shown or include anything else.
  • FIG. 1 requires the synchronous one Coil build-up at all workplaces. If the opportunity flying change full of coils may be desired the embodiment shown in Fig. 2 can be selected. At this is the coil bank 4 in always the same large stroke on and off moves. The necessary shortening of the thread laying with increasing Coil diameter is achieved here in that the Laying device 21 the stroke of the spool bank with increasing Coil diameter increasing correction stroke superimposed.
  • the discs 18 and 19 are at each work station mounted on a swivel arm 31 which by means of a. a drive 32 containing an electric stepper motor is pivotable up and down.
  • This drive 32 is controlled by means of a control device 33, which is the current coil diameter and the respective height position of the coil bank is abandoned. Due to the angular position of the coil 16 supporting swivel arm 10 is represented coil diameter detected by an angle encoder 34 on the shaft 11 of this coil arm and fed via line 35 to control device 33.
  • the height position of the coil bank 4 is determined by a linear scale 36 sensing sensor 37 and detected via line 38 fed to the control device 33.
  • the swivel arm 31 of a laying device stands 21 in the middle position.
  • the swivel arm 31 performs one of the lifting movements of the Spool bank following pivoting movement of increasing width, so that the constant laying stroke of the winding device 17 through the increasing, correcting correction stroke of the laying device 21 is increasingly reduced. In this way, one Job-specific parallel winding generated.
  • the control is in reset the starting position, i.e. the swivel arm 31 in the middle position.
