Definitions
- Machine for producing a knitwear made of fiber material in particular circular knitting machine
- the invention relates to a machine of the type specified in the preamble of claim 1 for producing a knitwear made of fiber material, in particular a circular knitting machine.
- Machines of this type are characterized by the fact that, instead of conventional yarns, predominantly or exclusively threads are used which consist of largely untwisted staple fibers arranged parallel to one another.
- Such threads are produced in draw frames, which are immediately upstream of the stitch forming sites of the machine from them fed Lunten or tapes and converted to ensure trouble-free transport of the drafting to the stitch forming sites with the aid of spin organs in temporary yarns whose turns only shortly before the enema be broken down again into the stitch formation points (false-twist principle).
- the actually processed into knit fabric threads therefore consist essentially of untwisted, parallel fibers, which is why the finished knitwear is characterized by an extreme softness. If necessary, additional auxiliary yarns consisting of classical yarns can be incorporated, but this is basically not necessary.
- a known machine designed as a circular knitting machine of the type described at the outset (PCT WO 2004/079068 A2) has a drafting system for each stitch formation point. Since the drafting systems can not be made arbitrarily small, it results in a significant space and handling problem. It is therefore provided, for example, to arrange the drafting systems with comparatively large distances from the circular knitting machine and to surround them with an elevated platform from which the drafting systems are accessible.
- the technical problem of the invention is to design the machine of the type described so that the drafting arranged even at high system densities close to the machine and yet easy to use, maintained and possibly repaired. This problem is solved by the characterizing features of claim 1.
- the invention has the advantage that the drafting systems can be operated from below and / or from the side in comparison to the hitherto exclusively customary manner.
- known pressure arms in which the so-called. Upper rollers are mounted, are arranged so that they can be pivoted downwards or to the side instead of upwards.
- Another preferred option is to mount at least selected functional parts, in particular drafting device elements such as rollers or straps, on a component which can be pulled downwards or sideways out of the associated drafting arrangement in the manner of an insertion part. This makes it possible to bring the drafting systems close to the stitch formation or knitting points, although they are preferably arranged above the knitting points, but nevertheless remain in the grip area of the operator working on the machine. The operator can therefore, without having to leave the usual work space to perform all necessary work on the drafting systems by folding the functional parts down or to the side or pulls out.

- the term "handle area” is understood to mean that area which preferably has an ergonomically favorable and / or z. B. by work instructions, standards or otherwise prescribed distance above a soil 7 od.
- the circular knitting machine 1 of interest in the context of the present invention is designed as a so-called spinning knitting machine.
- Each stitch formation or knitting point 6 is assigned to a drafting 8, which is fed to a tipped from a pot 9 sliver 10.
- This sliver 10 is refined in the drafting unit 8 in a conventional manner to a thread 11 and preferably presented by means of a Faderrschreibers 12 the knitting needles 3 for stitch formation.

- the embodiment of FIGS. 1 and 2 is characterized in that the axes of the drafting rollers 18 are all arranged horizontally in Nutzsmstand.
- the drafting 8 can be at least partially opened by their essential functional parts according to the invention are mounted at least partially pivotally downwards in the drafting units 8. This is indicated in Fig. 1 by a so-called.
- FIGS. 3 and 4 differs from the embodiment of FIGS. 1 and 2 mainly characterized in that the drafting 8 are here mounted in a relation to FIG. 1 rotated by 90 ° position on the circular knitting machine 1 and are arranged vertically instead of horizontally in use , The same parts are therefore provided in FIGS. 3 and 4 with the same reference numerals as in FIGS. 1 and 2.

False-wire effect be resolved again. Because of the selectable length of the radially to the circular knitting machine 1 arranged transport tubes 23, the distance of the drafting units 8 from the central axis of the needle cylinder 2 can be comparatively large and largely arbitrarily selected. As a result, the distance between two adjacent drafting units 8 that results in the circumferential direction can also be set to a preselected value enabling pivoting of the pressure arms 19. Corresponding spinning devices 21 can be provided in the exemplary embodiment according to FIGS. 1 and 2.
- FIGS. 3 and 4 compared to that of FIGS. 1 and 2 has the advantage that the drafting rollers 18, since they are perpendicular, extended in a simple manner by in the circumferential direction of the needle cylinder 2, circularly mounted and arranged above the drafting equipment Drive belt can be driven.

- FIG. 3 shows that here two or more drafting devices can be arranged with their rollers 18 coaxially one above the other. This makes it possible to halve or even reduce the space required in the circumferential direction for the drafting 8, since in this case, two or more threads from each drafting segment can be guided to adjacent knitting points, as shown in FIG. 3 by two threads 11th is indicated. As a result, the packing density stretched goods can be doubled or tripled.
- the invention has hitherto been described on the basis of drafting arrangements 8, which are distinguished by the fact that the axes of rotation of all drafting device elements, which may also include functional parts in the form of straps 24 (FIG. 4), are arranged parallel to one another.
- the axes of rotation of the embodiment of FIGS. 1 and 2 during operation are horizontal and the axes of rotation of the embodiment of FIGS. 3 and 4 arranged vertically.

- the pairs I and II of the drafting system members 28, 29 form a drafting zone 41, wherein the peripheral speeds of the drafting system members 28, 29 z. B. are selected so that a distortion of the fiber material 27 is obtained between 5 and 15 times, which comes close to the delay in a conventional flyer.
- the fiber material 27 is subjected to a main delay between the nip lines 28 and 39 or in a zone 42, which leads to an extension of the fiber material 27 z. B. leads to 50 times or more and to a preselected final fineness.
- the described drafting system 25 has at least two pairs of drafting devices which cause a folding of the fiber material 27. These are in Figs. 5 and 6, the pairs II and III, whose Klernmlinien 37 and 38 between them a Forming the folding zone 43. In contrast to the delay zones 41 and 42 takes place between the nip lines 37 and 38 only a tension distortion instead, preferably z. B. is 10% and just enough to keep the fiber material 27 stretched and to effect a defined folding.
- the center axes of the rollers 31 of the pair III are tilted or pivoted by 90 ° with respect to the center axes of the rollers 29 of the pair II.
- the center axes of the drafting device elements 28 are arranged parallel to those of the drafting device 29 and the center axes of the drafting device 35 parallel to those of the rollers 31.

- the distance D and the width B are set that results in a W-shaped fold and the original width B of the fiber material of B. 2 20 mm is reduced to a final width of about 5 mm.
- This width corresponds approximately to the diameter of a standard roving, with the result that the fibrous material reduced to this width can be spun in the usual way without further intermediate step and / or fed to the stitch-forming machines according to FIGS. 1 to 4.
- Such folding is achieved when the distance D is about twice as large as the width B.
- the conditions desired in the individual case can easily be determined by experiments.

- FIG. 5 shows that the driven roller 35b is rotatably mounted on a further component in the form of an arm 50, which is pivotably mounted with a pivot pin 51 on a part of the housing 46 which is at the very front in the direction of transport 26.
- the pivot axis is arranged parallel to the axis of rotation of the roller 35b. Therefore, the roller 35b can be pivoted in Fig. 5 downwards in accordance with a double arrow y_ from the drafting system 25 out in a dash-dotted line indicated position in which the functional part 35b and the exit slit between the straps 34a, 34b are accessible.

- the upper rollers 31b which are normally only entrained by frictional force, in FIG. 5 by positive locking.
- the driving roller 31a of the (lower) strap 34a in FIG. 5 is expediently driven by means of a toothed belt indicated by arrows r, which is wound around a toothed belt pulley 55 whose axis of rotation coincides with the pivot axis of the pivot pin 53.
- the toothed belt pulley 55 is preferably mounted on a shaft projecting through the entire drafting group, perpendicular to the input rollers 28a, 28b, from which the drives for the rollers 31a of the other drafting arrangements 25a, 25b, etc. are also derived.
- rollers 31a, 31b circumferentially with radial pins 56 (Fig. 6) which engage in holes 57 which are attached to the edges of the straps 34a, 34b and arranged one behind the other in the transport direction 26. This makes it possible to drive both straps 34a, 34b forcibly and completely without slippage, which promotes a uniform refinement of the fiber material 27.
- Fig. 5 shows schematically how, despite the hinged arrangement of the various functional parts, a suction / blowing air device can be provided in order to keep the drafting device 25 largely free of lint or the like.
- a suction / blowing air device can be provided on both sides of the output rollers 35a, 35b in order to keep the drafting device 25 largely free of lint or the like.

- the automatic threading the fiber material 27 is substantially facilitated in the largely closed drafting system 25.
- a distance 64 in FIG. 6 shows that the guidance of the folded fiber material 27 by the pair of rollers IV does not expediently take place exactly in the center in comparison with the fiber course in the roller pairs I and II. Since the usually occupied with a rubber layer rollers 35b (Fig. 5) because of the high speeds of z. B. 2000 rpm to 4000 rpm are subject to a certain wear, the rollers 35b can be turned if necessary. As a result, the running time of the rollers 35b can be doubled even without costly traversing.

- the fiber materials 27 are therefore, as there parallel to the bottom 7 ( Figures 1 and 3) and perpendicular to the knitting needles 3 by the Vorverzugs- and folding zones 67, 68 stirred before they are stirred into strappy assemblies 69 a, 69 b.
- Each two straps 70a and 70b of these assemblies 69a and 69b are placed around two rollers 71a, 71b and two deflecting elements 72a, 72b and form between them guide tracks 73, which at the exit of the rollers 29a, 29b approximately at the height of the predetermined by the transport direction 26 web begin and then extend obliquely downwards in the direction of the lower deflecting elements 72a, 72b.
- the inclination angle is z. B.
- the main drafting zone 66 connects with the parts 35a, 35b, 50, 51, 58 and 59, taking into account this inclination angle substantially in the same manner as in Fig. 5 .
- the fiber streams occurring are introduced obliquely into the knitting needles 3.
- a resulting from Fig. 7 difference from Fig. 5 thus consists in that the emerging from the drafting 65 threads may be introduced obliquely as in Fig. 5 in the knitting needles 3, but at the same time the pivotable pressure arms 44 (Fig. 6) and the arms 52 are lower in comparison to FIG. 5 and therefore are even more easily accessible to the operator 5, without restricting their headroom.

- the drafting system 74 is constructed analogously to FIG. 7 and provided with four pairs I to IV of drafting devices according to FIGS. 9 to 12.
- the first pair I includes two input rollers 80a and 80b which form a pre-delay zone with rollers 81a, 81b of the second pair II, while the fourth pair IV includes two output rollers 82a, 82b.
- the rollers 80a, 80b and 81a, 81b are vertical, while the rollers 82a, 82b are horizontal.
- two strapping assemblies 83a and 83b are arranged, which, analogous to FIG. 7, have rollers 84a and 84b, deflecting elements, not shown, and strapping 85a and 85b guided thereon.

- the conditions according to the above explanations are chosen so that the fiber material in the folding zone between the rollers 81a, 81b and 84a, 84b z. B. V-, N- or W-shaped, before it is fed by means of the straps 85a, 85b the exit gap between the output rollers 82a, 82b and is subjected to this of the main delay.
- the fibrous material emerging from the exit slit is then preferably converted into a temporary yarn by means of a spinning device 21 (compare FIGS. 4, 7 and 8) or another spinning element and transported to the knitting needles 3.
- a special feature of the drafting system 74 is that it can be at least partially opened by the fact that at least the strap assemblies 83 completely on a cassette-shaped, in Fig. 9, 9a, 11 and 12 by hatching made more visible component in the form of a Insertion part 89 are mounted.
- This insertion part 89 is seated in a downwardly open recess 90 (FIG. 9 a) of the housing 76 and has z. B. - considered in the transport direction of the fiber material - as leading and trailing boundaries each have guide surfaces 90a ( Figure 9a) which cooperate with corresponding guide surfaces 90b ( Figures 8, 9 and 9a) defining the recess 90.
- the guide surfaces 90b as shown in FIGS. 8 and 9, 9a, are vertical during operation.
- the insertion part 89 including the two strap assemblies 83a, 83b in the direction of a double arrow s can be pulled down from the drafting device 74, as shown in Fig. 9a, or be reused.
- the drafting system 74 is therefore arranged analogously to FIG. 3 above the stitch formation points 6, but in the grip area of the operator 5, then this is possible without leaving the working space 4, pulling the insertion part 89 downwards in order to move it into the apron assemblies 83 functional parts to maintain and / or repair.
- the position of the guide surfaces 90b parallel to the axis of rotation 87 (FIG. oblique position to the axis of rotation 87 may be provided, in which case the insertion part 89 would be pulled out obliquely downwards.
- the housing 76 and the insertion part 89 can be provided with cooperating, for better clarity omitted locking means and possibly also with other positioning means to correctly position the insertion part 89 in the position shown in FIG. 9 working position in the drafting system 74 and fix.
- the lower driven output roller 82b shown in Fig. 9 is also preferably mounted on the insertion member 89 (see Fig. 9a) so that its position relative to the driven apron 85b can be easily adjusted with the insertion member 89 pulled out.
- the insertion part 89 may be provided with spring elements, not shown, or the like, in order to press the driven strap assemblies 83b against the driving strap assemblies 83a.
- each drafting device 74 two drafting sections in tandem construction are preferably arranged next to each other analogously to FIG. Therefore, the drafting system 74, two inlet funnel 88, two pairs of input rollers 80a and 80b, two straps 85a, 85b, etc., so that at the same time two fiber materials refined in parallel operation and adjacent knitting points of the circular knitting machine 1 can be supplied.
- the driven rollers 80b of the pairs I are expediently arranged on the outer side of the housing 76 and are rotatably mounted there on pivotally mounted pressure arms 91 (eg, FIGS.
- the pressure arms 91 can be pivoted to the side and to the outside in the manner known per se by vertical pivot pins 92 (FIGS.
- the functional parts can be made accessible by pulling out the insertion part 89 downwards and / or the pressure arms 91 are pivoted to the side. If it is desired to make at least the driven output rollers 82b accessible independently of the other functional parts, they can be mounted analogously to FIG. 7 on a separate, downwardly pivotable arm.
- the pressure arms 91 may also be formed as shown in Figs. 4a and 4b.
- FIG. 10 also shows that the drafting devices 74 can be arranged very close to each other. Because of the described segmental design, they lie radially to the central axis 87 (FIG. 8) of the needle cylinder 2 and therefore have their smallest distance a where the filaments emerge, whereas they have larger distances b where the fibrous materials are fed.
- the drive for the driving rollers 80a, 81a of the first and second pair I and II takes place in the embodiment of FIGS. 8 to 12 by means of vertical drive shafts, are wound on the pulleys 94, 95.
- the desired gear ratio and the required direction of rotation can be adjusted by means of spur gears 96, 97 (FIG. 9).
- the drive for the driving rollers 84a of the strap assemblies 83a is transmitted from the drive shaft of the toothed belt pulley 95 to the horizontally lying shafts of these rollers 84a by means of bevel gears 98 diagrammatically indicated in FIG.
- the arrangement is suitably made so that these bevel gears 98 simultaneously represent clutches which cooperate with corresponding bevel gears on the shafts of the rollers 84a. Therefore, when pulling out the insertion part 89 from the drafting system 74 (FIG. 9a), its separation from the drive is automatically effected. If the insertion part 89, on the other hand, retracted into the drafting system 74, then the cooperating bevel gears are automatically coupled to each other drivingly.
- the driving rollers 82a of the output roller pair IV would, if they are to be driven by means of vertical standing waves, also be coupled via bevel gears with these waves. In view of the high rotational speeds of these rollers 82a, 82b, this could lead to problems or require costly gearboxes. According to the invention, it is therefore proposed to provide the driving output rollers 82a of the folding drafting systems 25, 65 and 74 with drives assigned to them individually. This is indicated schematically in FIGS. 9 and 9a, wherein a motor 99 is accommodated in the housing 76, which is drivingly coupled via a toothed belt 100 to a toothed belt pulley which is seated on the shaft of the driving output roller 82a. With the same motor 99, of course, both (or more) pairs of output rollers IV can be driven when the drafting units 74 are arranged as shown in FIGS. 8 to 12 for parallel processing of two (or more) fiber materials.

- the strap assemblies 105 and the nozzle assembly 107 are each formed as insertion parts 108, 109, which can be pulled out in the direction of arrows u down from the drafting system 102.
- the design of the insertion parts 108, 109 may be selected analogously to FIGS. 9 and 9a.
- coupling 110 for the insertion part 108 shows the strap assemblies 105 can be decoupled when pulling out of the insertion part 108 of overlying drive members whose axes are parallel to those of the rollers 106.
- the input rollers 103 and the output rollers 104 can also be arranged in a respective insertion part 103a, 104a, which is connected to a further coupling 110 to the drive or decoupled from it.
- the driven rollers of the pair I also in analogy in Fig. 8 to 12, mounted on a common, not shown, pivotable to the side of pressure arm, which could also be replaced by two individual pressure arms.
- the embodiment according to FIG. 14 differs from that according to FIG. 13 in that it is designed as a 4-roll folding drafting system 111 without kink K (FIG. 7).
- horizontal input rollers 112 of the first pair I and with these the Vorverzugszone forming during operation also horizontal rollers 113 of the second pair II in a insertion part 114 forming cassette are arranged.

- the axes of the input rollers 112 and the rollers 113 of the pair II are horizontal here, the axes of the belt assemblies 115 and of output rollers 116, however, arranged vertically. Therefore, the driving rollers of the pairs I and II, as indicated in Fig. 9 for the rollers 84a, e.g. driven by means of bevel gears 117, 118, which mesh with sitting on the shafts 112, 113 further bevel gears and at the same time serve as couplings when pulling out or insertion of the insertion part 114. As a result, the rollers 112, 113 are automatically coupled with the movements of the insertion part 114 with a non-illustrated, explained below drive or decoupled from these.
- the driven drafting system members of the apron assemblies 115 and the output rollers 116 may, analogously to FIG. 4, be mounted on the sides of the drafting system 111 such that the pressure arms can be swung away.
- a particularly preferred embodiment results if the apron assemblies 115 and the output rollers 116 are fastened analogously to FIG. 13 on insertion parts 115b and 116a, respectively, which can be pulled down in the direction of the arrows 1.
- FIG. 15 shows a four-roller drafting system 119, which is currently considered to be the best embodiment of the invention and which differs from that of FIG. 14 in that the axes of input rollers 120, apron rollers 121 and
- Output rollers 122 are all arranged vertically in operation, while further, arranged between the input and Riemchenwalzen 120, 121 rollers 123 have horizontal axes.
- the distances between the nip lines of these rolls become in proportion to the width of the fed fiber sliver chosen so that the folding required for the above-mentioned conditions are not met, for example by the distances of the nip lines are chosen to be much larger than the widths of the fiber ribbons.
- rollers 120 and 123 oblique or over an angle of 90 ° helically curved guide elements 124 od. Like. Are provided, on the one hand prevent folding, on the other hand promote a mere deflection of the sliver by 90 °.

- the distance between the nip lines of the rollers 132 and the rollers 133 of the Riem- chen assembly 130 with eg also 30 mm compared to the only about 4 "mm wide sliver set so large that there is no re-folding It would also be conceivable to arrange corresponding baffles between the rollers 132 and 133 of the baffles 124 according to Fig. 15. Moreover, the drafting device 127 can be realized simply by adding between the rollers of the second and third pairs of a conventional 4-roller drafting system the rollers 132 are installed.
- the embodiment of FIG. 16 has, moreover, as the exemplary embodiment of FIG. 15, the advantage that only one drive bevel gear 134 is required to drive the rollers 132, since the axes all other rollers 128, 129, 131 and 133 during operation vertically arranged and can be connected via the couplings 110. Therefore, it is usually sufficient to store only the rollers 132 in an additional insertion part 135 which can be pulled out in the direction of an arrow n down from the drafting system 127, while the other pairs of rollers analogous to Fig. 13 to 15 to the there described insertion parts can be stored. Apart from that, it is clear that the embodiments of FIGS. 14 to 16 could be provided with a nozzle 107.

- only two toothed belts and drive motors are required because the rollers 103 and 106 here z. B. by spur gears 150, 151 can be coupled to a drive shaft of the rollers 106.
- Figs. 13 to 16 show that in all cases either as insertion parts 108, 109, 114, 115b, 116a, 125 and 135 or as pressure arms designed components can be provided to analogous to Fig. 1, 3 and 8 all make essential functional parts of the workspace 4 accessible.
- it is expedient to use the insertion parts in particular where, according to FIG. 10 in the vicinity of the knitting points particularly small distances a of z. B. a few millimeters between the drafting units are desirable, since in such a case to the side swivel or sliding parts would hinder a close arrangement of the drafting systems.
- a particularly preferred for the purposes of the invention embodiment of a insertion part 153 is shown in Fig. 18.

- a cover plate 161 Fig. 13
- the parts 160 and 161 which in Fig. 13 to 15 schematically indicated couplings represent 110, automatically separated.
- the arrangement is such that upon retraction of the insertion part 153 in the drafting housing automatically the coupling pin 160 enters the coupling sleeve 163 and thereby connects the Riemchen- assembly with the associated drive.
- the housing 154 After the housing 154 has been attached to the cover plate 161, it is fastened with fastening screws screwed into the bore 155.
- the other described insertion parts with vertically arranged functional parts can be designed accordingly, wherein the straps are missing depending on the case.
- such insertion parts can also be provided, which are provided with horizontal functional parts (eg, 123 in Fig. 15).
- the bevel gears 98 described with reference to FIGS. 9, 9a or the bevel gears 118 or 126 shown in FIGS. 14 and 15 occur.
- Fig. 18 shows that the insertion part 153 according to the above-described tandem construction above and below the crossbar 154b each has a double-strap assembly.
- the shafts or drive rollers of these modules are only one-sided, d. H. on the side of the crossbar 154b and thus cantilevered so that the straps guided by them can be withdrawn and replaced after removal of the insertion part 153 from the drafting system upwards or downwards and replaced.

- the assembly of drafting on a stitch-forming machine in Fig. 1, 3 and 8 is shown only by way of example. In fact, it would also be possible to mount the drafting systems differently, in particular on a separate, close to the machine or this surrounding frame, for example, to retrofit an existing machine later with the described drafting equipment. It may also be advantageous, the straps, z. B.
- the strap assemblies 30a, 30b in Fig. 5, in Transport direction 26 form longer than usual and assign them an axially displaceable in the transport direction 26 clamping device that produces in the main drafting zone an additional clamping zone in the gap formed by the straps, as schematically indicated by an arrow in Fig. 5.
- the usual Klemmcreme can be adapted to the length of the fibers used and improve the uniformity of the exiting fiber materials.
