Definitions

  • the invention relates to a device for winding an element built up of at least one elongate, threadlike strand on a winding element, said device comprising a frame provided with at least: an inlet for the elongate, threadlike element, and a winding element to be rotatably driven about a winding shaft, said device furthermore comprising drive means at least for rotatably driving the winding element.
  • the fibre or the yarn (or generally an elongate, threadlike element) is wound on a winding element, such as a bobbin, for further processing.
  • the elongate, threadlike element may be composed of one or more strands.
  • the device disclosed in the present application is suitable for handling single-strand as well as multi- (more than one) strand, elongate, threadlike elements.
  • Such a method of producing a twisted or twined elongate, threadlike element is labourious, not only because of the additional operations that are required, but also because of the additional production time required for the twisting/twining step after the winding step.
  • the winding element, on which the synthetic fibre wound in many windings must be manually removed from the winding device and be placed into a separate twisting or twining device. This latter operation takes time, and because of the additional manual operations that are required, it is not attractive both for economic reasons and for ergonomic reasons.
  • the object of the invention is to provide a device as referred to in the introduction that does not exhibit the above drawbacks.
  • the winding device is characterized in that twisting means are mounted in the frame, which twisting means impart one or more turns per unit length to the elongate, threadlike element before said elongate, threadlike element is wound on the winding element.
  • turns means “twists” (in the case of a single-strand elongate, threadlike element) or “twines” (in the case of a multi-string elongate, threadlike element).
  • twisting means comprise a twisting shaft to be rotatably driven by the drive means, which twisting shaft is mounted in bearings in the frame, in such a manner that a first end of the twisting shaft is located within the frame and the other, second end of the twisting shaft is located outside the frame.
  • the drive means may at least partially be disposed outside the frame and drive the second end of the twisting shaft rotatably. This latter aspect ensures that the winding device is easy to operate (read:drive).
  • the twisting means are readily accessible in the frame, for example for maintenance purposes, whilst parts forming part of the fixed structure, such as the drive means, do not interfere with an optimum twisting or twining operation of the twisting means.
  • the winding element can be mounted in bearings on the winding shaft, and the winding shaft is connected to the first end of the twisting shaft via bearings.
  • the winding shaft is in line with the twisting shaft.
  • the winding device is characterized in that the twisting means furthermore comprise at least one radially extending twisting arm mounted on the first end of the twisting shaft, which twisting arm is provided with a feed-through channel for the elongate, threadlike element, which extends from the free end of the twisting arm to the twisting shaft.
  • the twisting arm may be provided with a guide eye at its free end, which guide eye connects to a feed-through channel.
  • the feed-through channel is a slot or a bore formed in the surface of the twisting arm, whilst furthermore the guide eye and/or the feed-through channel are provided with a material having an enhanced hardness. More specifically, the guide eye and/or the feed-through channel are provided with ceramic guide surfaces.
  • the twisting arm in order to obtain an improved stability of the twisting arm during its rotation about the twisting shaft, is provided with a counterweight at the other end of the twisting shaft, seen in the longitudinal direction of the twisting arm.
  • the twisting means by which additional turns (twists or twines) per unit length can be effectively imparted to the elongate, threadlike element, are characterized in that the twisting shaft is provided with a longitudinal bore, which bore connects to the feed-through formed in the arm on the one hand and to a winding bore formed in the winding shaft on the other hand.
  • the bore may be right-angled near the connection to the feed-through channel formed in the twisting arm, in which case also the winding bore may be right-angled.
  • the bore in the twisting shaft is provided with friction-reducing means, which means may comprise one or more ceramic guide surfaces in the bore.
  • a specific embodiment which provides a compact, lightweight but in particular very functional design of the present invention, is characterized in that the winding shaft is provided with a support, on which the drive means for the winding element are placed.
  • the support may consist of a first supporting shaft, which is connected to the winding shaft, and a second supporting shaft, which is pivotally connected to the first supporting shaft.
  • the drive means comprise a driving roller which is rotatably mounted to the second supporting arm and which can be placed into abutment with the winding element.
  • this manner of driving the winding element for the purpose of winding the twisted twined elongate, threadlike element not only provides a construction which is not only compact but also inexpensive.
  • the driving roller can be placed into abutment with the winding element with an adjustable, constant force by power means, which power means may comprise a gas spring or a tension spring.
  • a rotatably driven guide roller extending parallel to the driving roller is mounted on the second supporting arm, which guide roller is provided with winding grooves extending over the circumferential surface thereof for carrying the elongate, threadlike element to the winding element.
  • a guide element extending parallel to the guide roller may be provided on the second supporting arm, over which guide element the elongate, threadlike element can be carried in the direction of the guide roller. Possible blockage or other transport problem of the elongate, threadlike element through the winding device is prevented in this way.
  • the guide roller ensures a very uniform distribution of the windings over the winding element.
  • the first end of the twisting shaft is provided with circumferential teeth for driving the winding element via the driving roller, which teeth rotatably drive the driving roller and the guide roller via one or more gear transmissions upon rotation of the twisting shaft.
  • This specific driving construction provides a winding device whose winding and twisting means are mounted in the frame completely clear of the fixed structure and the drive means, which enables a much more efficient operation of the winding device.
  • the support is according to the invention provided with one or more guide wheels for guiding the elongate, threadlike element from the winding bore to the winding element via the guide element and the guide roller.
  • guide means are provided on the support, which guide means extend in radial direction, beyond the free end of the winding shaft, for carrying the elongate, threadlike element arriving from the inlet, over the winding element, towards the twisting arm.
  • the winding device according to the invention leads to a significant simplification of the production process of, for example, synthetic yarns.
  • the device can be directly incorporated in the production line (directly behind the yarn-producing device, such as an extruder), as a result of which twisting and winding of the yarn exiting the yarn-producing device can take place directly.
  • the yarn tension is easy to control by means of the twisting arm and the brake means on the inlet side, for example in case of yarn fracture. This, too, leads to a small-sized winding device.

  • the inlet opening 3 is formed in supporting beams 4 a 4 b , which supporting beams are pivot-mounted in the frame 10 . This makes it possible to swing the supporting beams 4 a provided with the supply opening 3 aside so as to provide better access to the interior of the frame 10 and the parts disposed therein for maintenance or repairs or for exchanging the winding element 5 with the elongate, threadlike element 8 that is wound thereon.
  • FIG. 2 is a more detailed view of the winding device according to the invention and of the relevant parts thereof.
  • FIGS. 3 a - 3 f the construction of the winding device is shown from several different angles.
  • a part of the winding device according to the invention that is known per se is the winding shaft 6 ( FIGS. 3 a - 3 c ), on which a winding element 5 can be mounted in bearings.
  • the winding element 5 is freely rotatable about the winding shaft 6 , therefore.
  • the free end 6 b of the winding shaft 6 is secured by means of a nut or a shackle pin, which prevents the winding element 5 from running off the shaft.
  • the essential element of the invention is the possibility to impart one or more turns (twists or twines) per unit length to the elongate, threadlike element before the elongate, threadlike element 8 is wound on the winding element 5 .

  • a freewheel coupling 7 c may be arranged between the twisting shaft 7 and the belt pulley 7 b.
  • the twisting shaft 7 is mounted in bearings in the girder 10 a of the frame 10 (see FIG. 1 ), in such a manner that the end 7 a of the twisting shaft 7 extends into the frame 10 .
  • a twisting arm 11 is mounted to the first end 7 a of the twisting shaft 7 , which twisting arm extends radially from the twisting shaft 7 .
  • the twisting arm 11 comprises a free end 11 a and a plate member 11 b , which functions as a counterweight.
  • twisting shaft 7 Since the twisting shaft 7 is mounted in bearings in the frame 10 , the twisting shaft 7 will rotate when driven by the drive means 2 , as will the radially extending twisting arm 11 .
  • the twisting arm 11 describes a circular motion with the twisting shaft 7 as its centre, with the free end 11 a of the twisting arm 11 describing a circle having a radius at least equal to, but preferably larger than the maximum radius that the windings 8 of the elongate, threadlike element may reach upon being wound on the winding element 5 .
  • the threadlike element is introduced into the frame 10 via the inlet opening 3 (see FIG. 1 ) and carried in the direction of the free end 11 a of the twisting arm 11 .

  • the twisting arm 11 is provided with a feed-through channel 13 , which feed-through channel 13 extends in longitudinal direction from the guide opening 12 towards the position at which the twisting arm 11 is mounted on the first end 7 a of the twisting shaft 7 .
  • the elongate, threadlike element that is introduced via the inlet opening is carried through the frame 10 and over the winding shaft 6 /the winding element 5 , through the guide opening 12 , and further in the direction of the twisting shaft 7 via the feed-through channel 13 .
  • the twisting arm 11 undergoes a circular motion, which motion causes the elongate, threadlike element being carried through the inlet opening 3 and the guide opening 12 to be flung round the winding shaft 6 .
  • guide means 38 a - 38 b are provided in the frame 10 .
  • the guide means 38 ( 38 b , see FIG. 3 f ) are arranged between the inlet opening 3 and the winding shaft 6 , extending in radial direction beyond the free end 6 b of the winding shaft 6 , therefore.
  • the guide means 38 a - 38 b are configured as a circular tube having a radius which is much larger than the maximum radius that the winding element 5 with the windings 8 can reach. More specifically, the external radius of the guide ring 38 a - 38 b at least equals the length of the twisting arm 11 , seen in radial direction.
  • FIG. 3 f shows another embodiment of a winding device according to the invention, in which two guide rings 38 a - 38 b are used instead of one guide ring 38 a , by means of which guide rings the creation of balloons in the elongate, threadlike element and jamming of the device and possible thread fracture are avoided.
  • FIGS. 5 a - 5 b show, the threadlike element being carried through the feed-through channel 13 of the twisting arm 11 via the guide opening 12 is carried through a bore 32 formed in the twisting shaft 7 .
  • the bore 32 connects to the feed-through channel 13 via a right-angled portion 32 a.
  • the first end 7 a is freely rotatably connected to the semi-fixed structure by means of bearings 29 , which semi-fixed structure is represented by the flange 35 of the winding element 6 and the support 18 (yet to be explained) comprising the supporting arms 18 a and 18 b.
  • the winding shaft 6 is freely rotatable in the frame 10 with respect to the twisting shaft 7 .
  • the flange 35 of the winding shaft 6 is likewise provided with a bore 32 , which connects to the bore 32 at the location indicated at 32 b .
  • the bore 32 in the winding shaft 6 likewise exhibits a right angle, so that the bore 33 opens into the outlet opening 34 , which outlet opening 34 is formed in the outer surface of the flange 35 of the winding shaft 6 . Since the winding shaft 6 , the flange 35 and the support 18 , 18 a - 18 b are stationary (semi-fixed structure) with respect to the rotating twisting shaft 7 , additional turns (twists or twines) can be imparted to the elongate, threadlike element that is being carried through the bore 32 .
  • the elongate, threadlike element exiting from the outlet opening 34 now comprises a number of turns (twists or twines) per unit length and must be wound on the winding element 5 in several windings.
  • the elongate, threadlike element is carried to a guide element 17 via a number of guide wheels 19 before the elongate, threadlike element is received in the winding groove of the guide roller 16 for the purpose of being wound on the winding element 5 .
  • the elongate, threadlike element thus runs from the last guide wheel 19 , over a guide disc 39 a of a yarn slackener in the direction of an eye 19 ′ bent into a pigtail shape.
  • the guide disc 39 a is provided with a groove (e.g. a flat groove or a V-shaped groove) for receiving the elongate, threadlike element and is driven by a rotary shaft (not shown) via a magnetic coupling (not shown).
  • Said magnetic coupling operates according to the eddy current principle.
  • Said shaft is carried through the yarn slackener 39 and is driven by the twisting shaft 7 via the gear transmission 24 , 25 , 26 and the first gear transmission 21 , 22 , 23 .
  • the guide disc 39 a rotates in the direction of transport of the elongate, threadlike element.
  • the velocity of the rotating guide disc 39 a is higher than the velocity with which the elongate, threadlike element is carried through the device. This enables the yarn slackener 39 to reduce any stretch that may be present in the elongate, threadlike element. Because of this, the hardness of the bobbin is maintained at a constant level. A very high yarn tension during the winding process leads to a hard bobbin.
  • the guide roller 16 (see FIGS. 3 b and 3 f ) is provided with a helical winding groove extending over the outer surface thereof, which groove functions to ensure that the elongate, threadlike element is evenly wound over the full length of the winding element 5 .
  • the drive means comprise a driving roller 15 , which can be placed into abutment with the winding element 5 , for winding the elongate, threadlike element on the winding element 5 .
  • the force with which the driving roller 15 presses against the winding element and the windings 8 is adjustable, for example by means of the gas spring or tension spring 20 .
  • the driving roller 15 , the guide roller 16 as well as the guide element 17 are mounted on a second supporting arm 18 b , which supporting arm 18 b is pivotally connected to a first supporting arm 18 a .
  • the supporting arm 18 a is mounted in bearings 29 on the first end 7 a of the twisting shaft 7 .
  • the construction consisting of the support 18 (the first support 18 a and the second support 18 b ) together with the driving roller 15 , the guide roller 16 and the guide element 17 , is mounted in the frame 10 in a free-floating manner.
  • the winding shaft 6 can be mounted on the first supporting shaft 18 , which functions as a semi-fixed structure, via the flange 35 .
  • the first supporting shaft 18 a is provided with a number of fixing openings 37 , which function to receive fixing pins 36 for connecting the winding shaft 6 to the first supporting arm 18 a .
  • FIGS. 5 a and 5 b clearly show, the winding element 5 is mounted in bearings 30 on the winding shaft 6 .
  • the driving of the driving roller 15 and the guide roller 16 for the purpose of winding the elongate, threadlike element on the winding element 5 takes place as follows.
  • the first end 7 a of the twisting shaft 7 is provided with circumferential teeth 21 near the twisting arm 11 (see FIGS. 3 b , 3 d , 3 f , 5 a and 5 b ), over which a geared belt 23 is passed for driving a first gear 22 that is mounted on the first supporting arm 18 a.
  • a geared belt is driven via several gear transmissions (see FIG. 3 e ), which geared belt 28 drives the driving roller gear 15 a and the guide roller gear 16 a (see FIGS. 3 b , 3 c , 3 e ) for rotating the driving roller 15 and the guide roller 16 , respectively.
  • the driving roller 15 is thus pressed against the winding element 5 (and the windings 8 already present on the winding element) for rotating the winding element 5 on the bearings 30 (see FIGS. 5 a and 5 b ).
  • the driving roller 15 pulls the elongate, threadlike element through the device.
  • the elongate, threadlike element is introduced into the frame 10 via the inlet opening 3 and carried in the direction of the twisting arm 11 , to which arm a circular movement in the frame 10 is imparted by the rotary twisting shaft 7 , carrying along the elongate, threadlike element over the guide ring 38 a ( 38 b ).
  • Said circular movement of the twisting arm 11 makes a first contribution towards imparting a number of turns (twists or twines) per unit length to the elongate, threadlike element.
  • the threadlike element is passed through the guide eye 12 , after which it is carried through the bore 32 via the feed-through channel 13 and the right-angled bore portion 32 a .
  • the elongate, threadlike element exits the bore 32 via the right-angled winding shaft bore 33 and the outlet opening 34 . Because the outlet opening 34 forms part of the semi-fixed structure (consisting of the winding shaft 6 with the flange 35 , the first supporting arm 18 a and the second supporting arm 18 b ), which does not rotate along, the rotating twisting shaft 7 again imparts turns (twists or twines) to the elongate, threadlike element in the bore 32 .
  • the outlet opening 34 After the twisted, elongate, threadlike element has exited the outlet opening 34 , it is carried over a number of guide wheels 19 before being wound on the winding element 5 by the driving roller 15 via a guide element 17 and the guide groove 16 b of the guide roller 16 .
  • the guide ring 38 a is mounted on the first supporting arm 18 a .
  • a second guide ring 38 b may be used, over which the elongate, threadlike element can be passed before the elongate, threadlike element is carried in the direction of the twisting shaft 7 via the guide eye 12 and the feed-through channel 13 .
  • the use of a second guide ring 38 b leads to a considerably improved operation of the device, because the elongate, threadlike element is prevented from getting entangled in the driving construction (the rotating parts) when a brief instability occurs in the balloon.
  • the guide eye 12 and/or the feed-through channel 13 may be provided with a material of enhanced hardness. More in particular, the guide eye 12 and the feed-through channel 13 may be provided with ceramic contact surfaces.
  • the feed-through channel 13 is configured as a slot in FIG. 4 , but it may also be configured as a through-bore in the twisting arm 11 .
  • FIGS. 7 a and the 7 b show another aspect of the device according to the invention.
  • the device is provided with brake means 40 near the inlet opening 3 , which function to carry the elongate, threadlike element towards the winding/twisting unit via the inlet opening 3 with a certain amount of internal stretched tension.
  • the brake means 40 are arranged on a supporting plate 46 , which is mounted on the supporting beam 4 a .
  • the brake means 40 comprise a first brake unit built up of three braking wheels 41 , 42 , 43 .
  • the braking wheels 41 and 43 are rotatably connected to the supporting plate 46 about a fixed pin, and the third braking wheel 42 is movably provided in a slot 46 a formed in the supporting plate 46 .
  • the position of the braking wheels 42 in the slot 46 a is adjustable, so that a certain internal yarn tension is imparted to the elongate, threadlike element as it is passed over the guide wheels 41 , 42 and 43 .
  • the tension in the elongate, threadlike element is very important for the quality of the final twisted and wound elongate, threadlike element and for the operation of the winding/twisting device.
  • the braking action provided by the braking wheels 41 , 42 , 43 on the elongate, threadlike elements moving past is more or less constant.
  • the brake means 40 furthermore comprise a second brake unit, which is built up of two rotatable reel elements 44 - 45 disposed one above the other, each reel element 44 - 45 being provided with a groove 44 ′- 45 ′ formed in the circumferential surface. Also refer to FIG. 7 b.
  • the elongate, threadlike element is guided from the first brake unit 41 - 42 - 43 into the parallel grooves 44 ′- 45 ′ of the two reel elements 44 - 45 in several windings before being introduced into the device through the inlet opening 3 .
  • one of the reel elements more in particular the reel element 44
  • the other reel element 45 is likewise rotatable on a shaft 45 a , but in this case the rotation of the reel element 45 is braked by a magnetic brake 51 .
  • the magnetic brake 51 which operates according to the eddy current principle, decelerates the elongate, threadlike element present in windings in the grooves 45 ′- 44 ′ as it runs off the reel element 45 in the direction of the inlet opening 3 , resulting in an adjustable internal yarn tension.
  • the brake may also be configured as a speed-dependent hysteresis brake, i.e. the braking action depends on the number of revolutions of the device. The higher the number of revolutions, the greater the braking action of the brake 51 on the elongate, threadlike element moving past. In this way a more stable balloon is obtained over the entire speed range of the device.
  • the offset and the magnitude of the braking action are adjustable.
  • FIG. 8 shows yet another embodiment of the twisting shaft 7 a .
  • the bore 32 through the twisting shaft 7 a is provided with friction-reducing means, in this embodiment in the form of ceramic rings 61 a - 61 b , which function as guide surfaces for the elongate, threadlike element moving past.
  • ceramic guide rings 60 a - 60 b are arranged near the transition 32 a between the feed-through channel 13 in the twisting arm 11 and the bore 32 on the one hand and near the transition 32 b between the bore 7 a and the winding bore 34 on the other hand. This prevents abrasion and possible fracture of the elongate, threadlike element.
  • the number of turns (twists or twines) per unit length in the elongate, threadlike element depends not only on the rotational speed of the twisting arm 11 and the twisting shaft 7 but also on the winding speed as imparted by the driving roller 15 .
  • the rotational speed of the twisting arm 11 and the twisting shaft 7 is directly determined by the rotational speed of the twisting shaft 7 as imparted thereto by the drive means 2 .
  • the velocity at which the elongate, threadlike element is carried through the device according to the invention is determined by the rotational speed of the driving roller 15 , which is determined by selecting the correct transmission ratio is for the geared belt.
  • the winding device according to the invention makes it possible to impart 35 ⁇ 2S- or Z-turns (twists or twines) per linear metre to the elongate, threadlike element.
  • the number of S- or Z-turns (twists or twines) in the elongate, threadlike element can be adjusted at will during winding when using the device according to the present invention.
  • twisting/twining and winding in one device makes it possible to increase the production rate of twisted or twined yarn or synthetic fibre considerably, which leads to a significant improvement as regards the productivity and production capacity, but also as regards the pay-off period.
