Definitions

  • the invention relates to a machine of the type specified in the preamble of claim 1 for the production of a knitted fabric made of fiber material, in particular a circular knitting machine, as they are known from DE 2451900 is well known.
  • 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 points of the machine from them supplied Lunten or tapes and converted to ensure trouble-free transport from the drafting to the Ma-schen Struktursstellen by means of spin organs in temporary yarns whose rotations until shortly before the inlet into the stitch formation sites are dismantled again (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, designed as a circular knitting machine of the type described ( 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. This makes it possible to arrange a large number of drafting devices on the circumference of the circular knitting machine, but this is achieved with the disadvantage that the operator working on the circular knitting machine, if an error occurs in one of the drafting units, leave the usual working space in front of the machine, enter the work platform, from there from the error and then return to the usual work space must.
  • 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.
  • 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 possibility 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 a push-in 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.
  • Fig. 1 and 2 schematically show a circular knitting machine 1 with a rotatable needle cylinder 2, are mounted in the knitting needles 3 slidably.
  • a working space 4 is schematically indicated, in which an operator 5 stops during normal work on the circular knitting machine 1.
  • the height of the circular knitting machine 1 is dimensioned in a conventional manner so that a plurality of stitch forming or knitting 6, which are formed by lock parts, not shown, and of which in Fig. 1 only one is shown in the grip area of the operator 5 is located.
  • 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 device 8 in a conventional manner to a thread 11 and preferably presented by means of a yarn guide 12 the knitting needles 3 for stitch formation.
  • an auxiliary thread is further indicated, which can also be supplied to the yarn guide 12.
  • drafting group 8a in the exemplary embodiment, which provide the threads 11 for six adjacent, here by the yarn guide 12 marked knitting points.
  • z. B six drafting 8 arranged coaxially horizontal rollers side by side, so that the Fig. 2 apparent, bar-shaped arrangement with z. B. four drafting groups 8a results, which are arranged on the circumference of the needle cylinder 2 and provide threads 11 for a total of 24 knitting points.
  • the drafting units 8 are arranged so that they are like the knitting points 6 in the grip region of the operating on the circular knitting machine 1 operator 5.
  • the drafting 8 z. B. attached to a support ring 15 which is supported by means of columns 16 on a base or lock plate 17 of the circular knitting machine 1.
  • the arrangement is also made such that the nip lines formed by three or more pairs of functional parts (eg drafting rollers 18 or the like) do not lie in horizontal planes but in a corresponding manner Fig. 1 lie in oblique planes, wherein the respective cans 9 facing input roller pairs are higher than the circular knitting machine 1 facing output roller pairs above the ground 7.
  • the embodiment according to Fig. 1 and 2 is characterized in that the axes of the drafting rollers 18 are all arranged horizontally in the use state.
  • 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.
  • the embodiment according to Fig. 3 and 4 differs from the embodiment according to Fig. 1 and 2 mainly in that the drafting 8 here in one opposite Fig. 1 rotated by 90 ° position mounted on the circular knitting machine 1 and are arranged vertically instead of horizontally in use. Same parts are therefore in Fig. 3 and 4 with the same reference numerals as in Fig. 1 and 2 Mistake. Pairs of associated drafting 8 come accordingly Fig. 4 to lie next to each other. Fig. 4 also shows that here the pressure arms 19, which carry the so-called top rollers (18a) are pivotable about pivot axes 20, compared to Fig. 1 are also rotated by 90 ° and are vertical.
  • Fig. 4a and 4b 4 shows a conventional pressure arm 19 and its actuating and locking elements 19a, 19b in the closed state (FIG. Fig. 4a ) and in the open state ( Fig. 4b ) demonstrate.
  • the pressure arms 19 have a sufficiently large swivel range and when opening a drafting system 8 does not encounter immediately against an adjacent drafting, according to the embodiment according to Fig. 3 and 4 as only in Fig. 4 is indicated, be provided that the drafting 8 leaving threads 11 are fed by means of spinning devices 21 to the associated knitting points.

  • 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 in the embodiment according to Fig. 1 and 2 be provided.
  • the embodiment has Fig. 3 and 4 towards the Fig. 1 and 2 the advantage that the drafting rollers 18, since they are perpendicular, can be driven in a simple manner by extending in the circumferential direction of the needle cylinder 2, circularly mounted and arranged above the drafting drive belt.

  • the drive torques transmitted by means of the toothed belts would have to be converted by means of bevel gears or the like into torques for the lower rollers arranged horizontally here.
  • Fig. 3 shows that here two or more drafting with their rollers 18 can be arranged coaxially one above the other. This makes it possible to halve or even more to reduce the space required in the circumferential direction for the drafting 8, since in this case, two or more threads from each drafting segment segment can be guided to adjacent knitting points, as in Fig. 3 is indicated by two threads 11. As a result, the packing density stretched goods can be doubled or tripled.
