Definitions

  • the object forming the basis of the present invention is to further increase the productivity of known circular knitting machines with structurally simple measures.
  • a circular knitting machine with a needle cylinder, in which cylinder needles are mounted to be longitudinally displaceable, and a dial, in which rib dial needles are mounted to be radially displaceable, which is characterised in that auxiliary elements, in particular sinkers, associated with the cylinder needles and auxiliary elements, in particular sinkers, associated with the rib dial needles, as well as separate thread feeds to the cylinder needles and to the rib dial needles are provided, and that separate tubular knits can be produced simultaneously or one after the other with the cylinder needles and with the rib dial needles.
  • tubular knits can be produced on the cylinder and on the dial at the same time, as a result of which productivity is doubled in comparison to conventional knitting machines.
  • the two tubular knits can be knitted identically or differently, e.g. in different colours.
  • the thread feeds can be formed by a joint thread guide with multiple eyelets or by multiple separate thread guides.
  • the circular knitting machine according to the invention can, of course, also be operated as a conventional machine, which produces a tubular knit only on the cylinder.
  • the production of a knit exclusively on the dial is also possible.
  • the removal of the produced webs can be performed in different ways.
  • tubular knits formed by the cylinder needles and the rib dial needles can be removable jointly by a removal device or by separate removal devices.
  • Knitted webs produced simultaneously on the cylinder and on the dial lie one inside the other.
  • a joint removal device equipped with a spreader and with a cutting device on both sides can be provided for these.
  • the produced knits can then be wound onto a double winder as four flat-lying webs.
  • a joint removal device which has an open frame and a cutting device on one side.
  • the two tubular knits lying one inside the other are cut open on one side and spread. They are then wound as two wide, flat-lying webs by a withdrawal winding roller.
  • the circular knitting machine can also have a removal device with an open frame and a removal device without an open frame. This allows one tubular knit to be wound up directly and the other tubular knit to be cut open, spread and wound as flat-lying web.
  • one or two folding devices are provided for the produced tubular knits. If four fabric webs are produced by cutting open the tubular knits on both sides, then four folding devices can also be provided.
  • auxiliary elements configured as sinkers perform a retraction movement and perform a raising movement on a withdrawing movement of the cylinder needles during stitch formation.
  • Very high knitting speeds can be reached as a result of this relative movement between the needles and the auxiliary elements, since the needles only need to perform approximately half the reciprocating movement in comparison to machines with fixed sinkers or sinkers that move with the needles in the same direction.
  • auxiliary elements are preferably configured as sinkers, latch needles, compound needles or bearded needles can be used as needles.
  • cylinder cam segments which have needle cams for controlling the raising and withdrawing movement of the cylinder needles and sinker cams, with which the auxiliary elements for the cylinder needles can be caused to perform vertical movements and/or a swivelling movement around a horizontal axis.
  • the auxiliary elements act as knock-over or holding-down sinkers and assure a reliable stitch formation.
  • dial cam segments can be provided, which have needle cams for controlling the raising and retraction movement of the rib dial needles and sinker cams, with which the auxiliary elements for the rib dial needles can be caused to perform radial movements and/or a swivelling movement around a horizontal axis. Because of the necessary radial movement at least of the rib dial needles, the configuration of the dial cam segments is clearly more complex than the configuration of the cylinder cam segments. This applies all the more, the smaller the diameter of the dial.
  • the auxiliary elements are also mounted respectively in the needle cylinder and the dial. They can thus be controlled jointly with the needles of corresponding cylinder and/or dial cam segments.
  • the auxiliary elements can also be mounted in separate devices like sinker rings. Control of the movement of the auxiliary elements in the dial by means of the dial cam segments is particularly demanding in this case.
  • the auxiliary elements must be radially moved and swivelled.
  • auxiliary elements can also be fixed knock-over bits.
  • Cam parts or other drive devices for moving the auxiliary elements can be omitted in this configuration.
  • cylinder needles and/or the rib dial needles can be configured as bearded needles and the associated auxiliary elements can be configured as beard-closing elements.
  • Circular knitting machines with correspondingly configured cylinder needles are known, for example, from GB 188449 A1 or GB 114144 A1.
  • the dial can be height-adjustable and the auxiliary elements and the thread feed to the rib dial needles or the thread feed to the cylinder needles can be rendered inoperative, so that a fine rib tubular knit can be produced jointly with the cylinder needles and with the rib dial needles.
  • FIG. 1 is a schematic partial view of a needle cylinder and a dial of a circular knitting machine according to the invention
  • FIG. 2 is a view corresponding to FIG. 1 of the circular knitting machine with lowered dial;
  • FIG. 3 is a detail view of a cylinder cam part of the circular knitting machine from FIG. 1 ;
  • FIG. 4 is a detail view of a dial cam part of the circular knitting machine from FIG. 1 .
  • FIG. 1 The detail view of a circular knitting machine 10 in FIG. 1 shows a needle cylinder 11 and a dial 12 .
  • Cylinder needles 13 are mounted to be longitudinally displaceable in the needle cylinder 11 .
  • Each needle 13 has an associated auxiliary element 15 in the form of a sinker for stitch formation.
  • rib dial needles 14 and associated auxiliary elements 16 in the form of sinkers are mounted in the dial 12 .
  • a thread 17 , 18 is fed respectively to both the cylinder needles 13 and to the rib dial needles 14 .
  • a first tubular knit 19 is produced from thread 17 by means of the cylinder needles 13 .
  • the rib dial needles 14 at the same time form a second tubular knit 20 from thread 18 , which lies within the first tubular knit 19 and is removed together with this. Therefore, with the represented circular knitting machine 10 double the amount of fabric can be produced at the same time as on conventional circular knitting machines. It is, of course, also possible to produce the tubular knits 19 and 20 one after the other. In this case, the tubular knits 19 and 20 can even be produced in different fineness qualities, patterns and colours.
  • FIG. 1 shows the circular knitting machine 10 with a dial 12 raised in relation to the needle cylinder 11
  • machine 10 in FIG. 2 is represented with the dial 12 in a lowered position.
  • the sinkers 15 and 16 are in a non-operating position. Only one thread 17 is fed, from which the cylinder needles 13 and the rib dial needles 14 jointly produce a fine rib tubular knit 21 .
  • FIG. 3 shows a detail drawing of a cylinder cam segment 30 of the circular knitting machine 10 from FIG. 1 .
  • the movements of the cylinder needles 13 and the sinkers 15 are controlled with the cam segment 15 .
  • a needle control cam 32 into which the needles 13 engage with a butt 33 , is provided to control the vertical movements of the needles 13 in the direction of double arrow 31 .
  • the sinkers 15 perform vertical movements in the direction of double arrow 34 as well as a swivelling movement around a butt 35 .
  • the butt 35 is mounted in a control cam 36 , which controls the vertical movements.
  • Upper and lower swivel cams 37 , 38 are provided for the swivelling movement.
  • the cam segment 30 is configured in such a way that the needles 13 and the sinkers 15 are movable relative to one another, i.e. the sinkers 15 are retracted during a raising movement of the needles 13 and raised and swivelled during a retraction movement of the needles 13 . This leads to relatively small vertical movements of both the needles 13 and the sinkers 15 , which allows very high machine speeds.
  • FIG. 4 shows a dial cam segment 40 of the circular knitting machine 10 from FIG. 1 configured in a similar manner to the cylinder cam segment 30 .
  • the rib dial needles and the associated control cam for their radial movements have been omitted from this drawing for reasons of clarity.
  • the cam segments 40 are arranged above the dial 12 and have a first control cam 41 for the radial movement of the sinkers 16 on their underside.
  • the sinkers 16 also perform swivelling movements, which are controlled by a front and a rear swivel cam 41 , 43 .
  • the centre of rotation for the swivelling movements lies in the control cam 41 .
  • the dial cam segments 40 are also configured in such a way that the rib dial needles 14 and the sinkers 16 perform relative movements in order to shorten the relative movements of the needles.
  • the circular knitting machine shown in FIGS. 1 to 4 is merely a possible exemplary embodiment of a circular knitting machine according to the invention.
  • Compound needles or bearded needles could also be used in place of the shown latch needles 13 and 14 .
  • the auxiliary elements 15 and 16 do not have to be sinkers, instead they can also be configured as beard-closing elements, for example.
  • the simultaneous formation of knits on the needle cylinder and the dial is also possible with such variants.
