Definitions

  • a disadvantage of the transport described is that dirt particles, nits, short and foreign fibers and other, loosely adhering to the fiber material and entrained by this foreign body can lead to errors in the knitwear and soiling of the mesh formation organs. Unlike normal spinning are no winder od. Like. Exists, detected by means of which impurities and other defects in the fiber material and possibly can be eliminated by cutting the temporary yarn and subsequent splicing.
  • the technical problem of the present invention is to design the initially described device so that it is easier to handle, can be easily adapted to the needs of the case and allows even more effective cleaning of the fiber stream.
  • the suction device can adjoin an open gap, ie. H. no closed system is needed for the air duct, which facilitates access to the various components.
  • Fig. 1 shows roughly schematically in a vertical partial section a stitch-forming machine in the form of a circular knitting machine 1 with a needle cylinder 2, are slidably mounted in the usual knitting needles 3, which at a designated below as a knitting knitting with the aid of lock parts, not shown in a for receiving fiber material suitable receiving position can be moved.
  • the circular knitting machine 1, the z. B. can be configured as a right / left circular knitting machine, stands on an indicated by the reference numeral 5 bottom of a hall or a knitting room. From the hall floor 5, an operator can operate the knitting machine 1. In addition, 5 more cans 6 are parked on the hall floor, in which existing fibers 7 Lunten are stored.
  • the Lunten 7 are od over conveyor belts 8.
  • a drafting 9 supplied, which is accessible to the operator of a above the hall floor 5 arranged working platform 10 from.
  • each knitting system, if necessary, an auxiliary thread 12 are supplied, which is withdrawn from a supply spool 14.
  • the auxiliary thread 12 can either directly by means of a thread guide directly or, as Fig. 1 shows are fed via an output roller pair 11a of the drafting system 9 the knitting system.
  • FIG. Fig. 2 A coming from the drafting 9, not shown fiber strand, which consists of substantially untwisted, mutually parallel staple fibers is, as is more accurate Fig. 2 can be seen, fed to an associated knitting system by means of a generally designated by the reference numeral 15 transport device.
  • the transport device 15 contains at least one swirl element 16 and a spinning or transport tube 17 (FIG. Fig. 2 ), in the embodiment according to Fig. 1 because of the comparatively large distance of the circular knitting machine 1 from the drafting system 9 three transport units, each having a swirl member 16a, 16b, 16c and a transport pipe 17a, 17b, 17c, are connected behindereinder.
  • the first swirl element 16a in the transport direction of the fiber material 4 is arranged directly behind the pair of output rollers 11a and the exit section 18 of the drafting system 9, while the last transport tube 17c in the transport direction is arranged close to hooks 19 (FIG. Fig. 2 ) ends at the respective knitting system in the fiber receiving position driven knitting needles 3 ends.
  • a suction element 20 may be arranged, the z. B. is connected to a central suction 21.
  • the ends of the air ducts 25 adjoining the outside of the body 23 are supplied with compressed or blast air by means not shown the swirling member 16 draws the fiber material appearing in the exit nip 18 of the pair of outgoing rollers 11a into the transporting pipe 17 and at the same time also passes it through the transporting pipe 17 in the direction of the knitting system in question. Because of the oblique arrangement of the air ducts 25 also air vortex 26 are generated in the transport tube 17 so that the coming of the output rollers 11a fiber material is not only sucked, but also spun to the temporary yarn 22 by a large number of revolutions are granted, which Compact fiber material at the same time.
  • the temporary yarn 22 retains the rotations substantially to the end of the transport tube 17, whereupon these rotations are then dissolved again until the fiber material 4 enters the knitting needles 3, ie they are reduced to zero (false-twist effect). Therefore, a compacted but almost untwisted fiber material 4 enters the knitting needles 3.
  • Fig. 1 three transport units from twisting organs and transport tubes 16a / 17a to 16c / 17c are connected in series. These transport units may be in accordance with Fig. 1 be arranged with preselected angles relative to each other, whereby it is possible to transport the refined, coming from the drafting 9 fiber material over relatively long distances without being damaged.
  • Circular knitting machines of the type described are z. B. from the documents PCT WO 2004/079 068 A2 and DE 10 2006 006 502 A1 which are hereby made the subject of the present disclosure in order to avoid repetition by reference to them.
  • Fig. 3 shows analogously to Fig. 1 a drafting system 9, in contrast to Fig. 1 two adjacent transport paths for fiber material and therefore each have two adjacent transport units 16a, 17a and 16b, 17b and 16c, 17c.
  • Fig. 3 shows analogously to Fig. 1 a drafting system 9, in contrast to Fig. 1 two adjacent transport paths for fiber material and therefore each have two adjacent transport units 16a, 17a and 16b, 17b and 16c, 17c.
  • the lower rollers 11, 11a of the drafting system 9 are shown to simplify the illustration.
  • Fig. 3 one each at the end of each last transport tube 17c arranged yarn guide 30 through which the supplied fiber material 4 the knitting needles 3 is supplied ( Fig. 2 ).
  • the negative pressure in the regions adjoining the gaps 27a, 27b takes into account the blowing air emerging from them and the blowing air generated by the respective swirling element (eg 16a) and the suction capacity of the swirling element adjacent to the relevant gap 27a, 27b (For example, 16b) should be adjusted so that on the one hand achieves a favorable cleaning effect and on the other hand, the transport of the temporary yarn 22 when passing through the gaps 27a, 27b and the remaining sections of the transport route is not affected.
  • the angle at which the end surface 33a is inclined relative to the axis of the transfer tube 17a may be different, as in FIG Fig. 4 a comparison with an inclined end face 33b at the outlet end of the transport tube 17b shows.
  • FIG. 4 Thus, as a whole, an embodiment with an obliquely downwardly pointing end face (eg 33a in FIG Fig. 4 ) in combination with an attached from below to this suction device 31, z. B. in the position 31a2. Loose entrained particles are particularly easily excreted from the fiber stream or temporary yarn 22 in this case, assisted by gravity.
  • the inlet end of the subsequent transport tube through this itself, as in Fig. 1 is indicated, or also by the inlet opening of a swirl member (eg 16b) connected to the respective transport tube. That depends on the particular construction and z. B. depends on whether the twisting element is arranged in front of the inlet end of the transport tube or is penetrated over its entire length from the transport tube. Overall, therefore, the length x indicates the smallest distance between two transport units each consisting of a swirl element 16 and a transport tube 17.
  • a further advantageous embodiment provides, although the transport tubes 17a, 17b and 17c all straight form and arrange with mutually parallel axes, however, to provide a transversely to the transport direction v extended offset between the axes of successive transport tubes.
  • Fig. 4 shows, z. B. between the axes of the transport tubes 17 a and 17 b, an offset or distance A1 and between the axes of the transport tubes 17 b and 17 c offset A2.
  • Fig. 9 shows another preferred and currently considered best embodiment of the invention, in contrast to Fig. 4 only two transport units, each with a swirl element 35a, 35b and a transport pipe 36a, 36b connected thereto are shown, although three or more transport units could also be present here.
  • the parts 35a, 36a form here a preceding and the parts 35b, 36b a subsequent transport unit.
  • an open gap 39 is provided, which is intended to form a vent opening.
  • a suction device 40 is arranged. This points contrary to Fig.
  • a suction chamber 42 connected to a suction pipe 41, which is closed off by a first end wall 42a and a second end wall 42b which expediently lies parallel thereto, which are arranged substantially perpendicular to the transport direction of the fiber material and at a distance from one another.
  • the transport tube 36a of the preceding transport unit projects through a passage of the first end wall 42a and extends with its free, the outlet end 37 forming end portion to the gap 39 and arranged there second end wall 42b.
  • This end wall 42b is provided with an exit opening 43 opposite the entry end 38a of the following transport unit, whose inner cross section is larger than the outer cross section of the transport tube 36a of the preceding transport unit at this point.
  • the invention is not limited to the described embodiments, which can be modified in many ways.
  • the described and apparent from the drawing angle at which the end faces are chamfered at the outlet ends of the transport units to be considered as examples, which may be departed from as appropriate.
  • the transport tubes 17 and 36 can have other than the here implicitly assumed, circular inner contours. If the contours deviate from the circular shape, it is expedient to use the dimension of the mean inner diameter of a transport tube as a measure. Further, it may be appropriate to use transport tubes whose inner diameter gradually from the inlet openings in the direction of the Auseriesöffinieux, z. B.
