Definitions

  • the invention relates to a circular knitting machine in the preamble of claim 1 specified genus.
  • a tubular one is usually used first Knitwear produced, which then folded into a double-layer web, in this Form fed to a take-off and / or winding device and finally to a Take-up roller is wound up or otherwise deposited.
  • a take-off and / or winding device is fed to a take-off and / or winding device and finally to a Take-up roller is wound up or otherwise deposited.
  • a spreader is usually arranged in the means producing the knitwear.
  • Circular knitting machines of the type described at the outset are therefore already known that serve the purpose, not the one coming out of the machine, closed Tubular goods, but one cut open on its long side and then onto the pulling off and winding up the double-width spread fabric (DE-T2-069 121 291, US-A-5 566 558, WO-A-00/506 78).
  • deduction and if necessary also winding rollers are provided, which are about twice as long as their usual length have, and the machine diameter must be much larger in this case fail than is common practice.
  • An advantage of this type of machine is in it seen that the two arise when winding a tubular knitted fabric Buckled edges are eliminated.
  • the invention has the advantage that the faults observed so far in spread material can be largely avoided. This is attributed to the fact that the knitwear also in the between the spreader and the junction of the V-roller area is performed and z. B. at a radial distance can be held by the machine axis, which is essentially that of the spreader manufactured radial distance corresponds. This will remove the fabric after leaving the Breithalters up to where it runs onto the junction of the V-rollers, on undesirable radial movements prevented and without formation of jams on the V-rollers transferred.
  • a circular knitting machine contains a frame 1, which in the embodiment three spaced at angular intervals of approx. 120 °, radially from the machine externally projecting feet 2 to 4, wherein the foot 2 is a main foot and each of the Feet 3 and 4 is a side foot.
  • the main foot 2 does not serve to accommodate one shown drive motor and other electrical or electronic assemblies as well as controls for the circular knitting machine, while the side feet 3, 4 to on an existing switch unit are free of such units.
  • the frame 1 also has an upper support ring 5, in which a cylinder support ring 6 is rotatably mounted, on which a needle carrier 7, only schematically indicated, is in shape a needle cylinder is attached, which together with the cylinder support ring 6 by one
  • the central or machine axis 8 of the circular knitting machine is rotatably mounted in the frame 1.
  • the support ring 5 serves u. a. to accommodate a conventional, the needle carrier 7 surrounding Castle shell, of which only one segment 5a is shown for the sake of simplicity.
  • the frame 1 has a lower support ring 9, which with the help of auxiliary feet 10 can be parked on the floor.
  • the lower support ring 9 is used for rotating Storage of a turntable 11 on which a frame 12 is attached, the one in general carries the take-off and / or take-up device designated by the reference number 14, by means of which a knitted fabric 15 produced by the needle carrier 7 and indicated in FIG. 3 can be drawn off and wound up.
  • the frame 12 contains two fixed or in an upper section rotatably mounted deflection rods 16, in a section immediately below two fixed or rotatably mounted, preferably substantially horizontal and V-shaped arranged V-rollers 17 intended for spreading the knitted fabric, below of these and in a central part of the frame 1 two or more, synchronized with the V-rollers 17 rotatable and rotating take-off rollers 18 and in a lower section finally a loosely rotatably mounted winding roller 19 in the frame 12, at least a drive roller 20, which bears against its circumference, is associated with the roller during operation the circular knitting machine knitted fabric 15 supplied by the take-off rollers 18 in known Way on the take-up roller 19.
  • the circular knitting machine a cutting device 21 mounted in the frame 1 and provided with a rotatable knife on, which serves the purpose of knitting fabric 15 coming from needle carrier 7 after or if necessary, also before passing the deflecting rods 16 along a side line cut open.
  • the cutting device 21 is preferably displaceable on a rod 21a, to allow adaptation to different fabric widths.
  • the V-rollers 17 can either stand still or rotate and if necessary with the help of a separate rotary drive, e.g. B. a drive shaft, regardless of the take-off rollers 18th be driven.
  • the knitted fabric coming from the needle carrier 7 15 spread out along the cutting line by means of the V-rollers 17 until they have a single-layer, in forms a substantially flat path, and then with the help of a rotatably mounted in the frame 1 Deflection roller 22 (FIGS. 2 and 3) the take-off rollers 18 and from there the take-up roller 19 fed. It is then wound up by this with a width twice that Width of the one produced with the needle carrier 7 and normally on opposite Side edges folded, two-layer tubular goods corresponds.
  • At least one driver 23 is provided on the underside of the cylinder support ring 6, which is used for synchronous rotation of the frame 12 with the cylinder support ring 6 and in a coupling receptacle 24 is attached.
  • a spreader 25 is arranged within one of the means 5a. This serves the purpose of section 15a in a double-layer, flat web 15b to convert the spreading device containing the V-rollers 17 in this form is fed.
  • Circular knitting machines of this type are generally known and therefore need a person skilled in the art not explained in more detail (DE-T2-691 21 291, US-A-5 566 558, WO-A-00/506 78).
  • the shape of the spreader 25 used according to the invention results in particular from 4 and 5.
  • the spreader 25 contains two parallel and arranged in an upper plane, comparatively long rods 26 and 27, at the ends of each one obliquely downwards extending, comparatively short rod 28 to 31 is attached.
  • Bars 28, 29 5 and 30, 31 also run toward one another in pairs in a triangular shape and are connected in pairs at their free ends in such a way that the connection points each form a first and second lateral end 32, 33, which in a lower, for upper level parallel level of the spreader 25 is located.
  • the length of the spreader 25 significant distance of the ends 32, 33 is therefore compared to that perpendicular to it measured distance of the upper rods corresponding to the width of the spreader 25 26, 27 comparatively large.
  • the two ends 32, 33 are further connected to one another by a rod 34.
  • the Rod 34 is like the rods 26, 27 preferably made of z. B. three telescopic mutually displaceable and fixable relative to each other by means of adjusting screws 35 Sections. Therefore, the length of the spreader 25 can be solved by loosening the set screws 35, moving the sections and then tightening the set screws again 35 can be changed.
  • a pivot bearing 36 e.g. in the form of a sleeve, arranged by means of connecting arms 37 on the rods 26, 27 and optionally 34 is attached and for rotatably receiving a holding rod 38 serves. This can, in a manner known per se, coaxial to the machine axis 8 (FIG.
  • the end 32 could be formed exactly like the end 33 and the Cutting device 21 can be arranged completely under the spreader 25.
  • the knife of the cutting device could also protrude between the rods 30, 31.
  • FIG. 4 the relative position of the reference to FIG. 1 is also shown in an enlarged view to 3 described deflecting rods 16 and V-rollers 17 can be seen, whose axes in essentially lie in planes that go to the upper and lower planes of the spreader 25 are arranged in parallel.
  • This material web 15b is then, as described, through a narrow, out between the deflection rods 16 formed by the cutting device 21st Continuously cut on a lateral longitudinal fold and with the help of the V-rollers 17 spread.
  • the deflecting rods 16 are fixedly or rotatably mounted in bearings 42.
  • a guide element 44 is arranged according to the invention.
  • the guide member 44 is z. B. a rod, especially a round rod, and with one end at the bottom of the second end 33 of the spreader 25 attached.
  • the guide element protrudes from this 44 preferably essentially parallel to the machine axis 8 (FIG. 3) downwards, its outer radial distance from the machine axis 8 preferably to close the connection 43 approach substantially the same as the radial distance of the Outside surface of the end 33 of the machine axis 8 is.
  • the guide element 44 is bent radially inward along a section 44a or curved and extends to the junction 43, so that one radially outside lying guide surface of the guide element 44 there a soft, heel-free Transition area to the beginning of the V-rollers 17 creates. It is in principle regardless of whether the two deflecting rods 16 are additionally present or not. are the deflecting rods 16, which is expedient, then the guide element 44th at least so thin that it protrude through the gap between the deflecting rods can, as Fig. 4 shows.
  • connection point 43 between the V-rollers 17 is according to a preferred embodiment the invention formed by a head piece 45 (Fig. 6).
  • the V-rollers 17 can be rotated and / or swiveled and / or with not shown as required Fixing screws can be fixed non-rotatably on the lugs 46.
  • the head piece 45 also preferably has a receptacle 47 for the associated, radially inwardly bent end 44a of the guide element 44.
  • V-rollers 17 can be pivoted in a corresponding manner by means of the lugs 46 to store that the angle they enclosed is changeable.
  • the V-rollers can also be rotated and / or rotated in other ways depending on the needs be pivotally arranged.
  • a particularly important advantage of the guide element 44 is that it can be made comparatively thin. Good results are e.g. B. with a achieved a maximum of 9 mm thick round rod, the bent end 44a of a length of 77 mm. But also z. B. diameter of the guide element 44 from 2 mm to 40 mm are usable. Because of this construction, it is possible that trained as a knee Headpiece 45 transverse to the gap between the deflecting rods 16 even then comparatively train broadly if this gap is chosen very narrow. Such as B. Fig. 4 shows According to the invention, the flattened fabric is not by the head piece 45, but spread apart by the thinner guide element 44 and only then on the V-rollers 17 transferred.
  • the invention is not restricted to the exemplary embodiment described, which is based on can be modified in numerous ways. This applies in particular to training and Arrangement of the guide element 44.
  • These include in particular Arrangements expedient, the adjustment of the guide element 44 in the radial and / or axial direction and thus in each case the production of a position of the guide element 44 enable that depending on the individual case as the convenient location is felt.
  • the guide element 44 is made of one material should be produced, that compared to that used to manufacture the knitted fabric 15 Yarn ensures the best possible friction. Furthermore, the Invention does not apply to the described size specifications for the guide element 44 limited, which are only to be regarded as examples.
  • the needle carrier 7 could instead of Needle cylinder can also be designed as a dial or in addition to the needle cylinder also include a dial. Finally, it is understood that the different characteristics also used in combinations other than those shown and described can be.
