Definitions

  • the invention relates to a flat knitting machine with at least two needle beds, with at least one movable over the needle beds away, occupied with knitting scooters and a yarn feeding with arranged above the needle beds yarn guide rails, in which are arranged by the at least one slide mitbewegbare yarn guide.
  • Such flat knitting machines correspond to the usual state of the art for many years. Increasingly, however, higher demands are placed on the patterning and the design of knitted pieces. In order to Also increase the demands on the machines for the production of such knitted fabrics, in particular of intarsia crocheted or of plated fabrics.
  • the US Pat. No. 5,615,562 discloses a special yarn guide which is self-propelled and can perform movements in and across the carriage direction.
  • the present invention has for its object to provide a flat knitting machine can be produced with the conventional knitted fabrics and knits with elaborate patterns or plated knitwear in a rational manner.
  • the flat knitting machine according to the invention thus provides a combination of a conventional thread feed, in which the thread guides are taken by suitable means of the carriage, and carriage-independently driven thread guide, both concepts of thread feed retain their full functionality. This is advantageous over some of the yarn feeding devices mentioned above, which are a compromise between the two types of yarn feeding.
  • each self-sufficient thread guide can have its own drive device in order to fully exploit the variability of the thread feed can.
  • the autarkic thread guide (s) are longitudinal in one or more separate thread guide rails slidably arranged. They can be moved in these rails over the entire length, without having to consider possible collisions with a guided by the slide yarn guide.
  • the yarn guide rails with mitbewegbaren from the carriage yarn guides and the yarn guide rails with autarkic yarn guides are alternately arranged parallel to each other above the needle beds to create similar conditions for the thread feed to the needles for both yarn guide types.
  • four yarn guides are arranged in the yarn guide rails for self-sufficient yarn guides.
  • yarn guide rails for the carriage mitbewegbaren yarn guide eight yarn guides can be arranged in each case.
  • the self-sufficient yarn guides and the co-moving with the slide yarn guide are arranged in common yarn guide rails. There are then fewer rails required than in a design with separate rails for the autarkic thread guide.
  • the self-sufficient yarn guide can be arranged in each case in one half of a rail and the movable mitschaubaren by the carriage yarn guide in the other half of the rail.
  • the self-sufficient yarn guide and be moved by the carriage with movable yarn guide in at least one of the halves of the yarn guide rail together.
  • a further alternative consists in that at least one half of one or more thread guide rails has two superimposed tracks, one or more independent thread guides being arranged in one of the tracks and one or more thread guides being moved by the carriage in the other track.
  • the yarn guide rails are at least partially disposed in a common horizontal plane above the needle beds.
  • the yarn guide arms are radially aligned with such an arrangement of the rails and all have the same shape and length, which allows for easier replacement and allows a more cost-effective and time-saving production.
  • the arrangements of the yarn guide rails described need not necessarily be symmetrical to the central axis of the knitting machine. Also asymmetric arrangements are conceivable.
  • the threads can be fed laterally as is usual.
  • the flat knitting machine may also have a carriage having an opening on the top has, are fed through the threads to the thread guides and further to the needles in the needle beds.
  • this solution can be dispensed with a whole series of Fadenleit- and thread tensioning elements, which are required for a lateral feed of the threads.
  • the thread tension is reduced by reducing the friction points in such a thread feed.
  • Fig. 1 shows a flat knitting machine 100 with a front needle bed 10 and a rear needle bed 10 'in cross section.
  • a carriage 20 is movable, are attached to the front and rear knitting locks 30, 30', with the knitting tools not shown here, which are stored in the needle beds 10, 10 ', can be controlled and moved .
  • the two needle beds include a comb gap KS between them. This is located on a central axis M of the flat knitting machine 100.
  • the outer thread guides 40, 40 ' which are further away from the machine axis M, are conventional thread guides which can be moved by the carriage 20 via catching means, not shown here.
  • the inner thread guides 50, 50 ' are self-propelled thread guides, which can thus be moved independently of the carriage 20. An up and down movement of the Fadenchangingarms or the Fadencoordinatingnüsschen is possible.
  • the arrangement of the yarn guides 40, 40 'and 50, 50' with respect to the stitch axis M is merely exemplary.
  • the thread guides 50, 50 'could also be arranged outside or in alternation with the thread guides 40, 40'.
  • the yarn guides 40, 40 'and 50, 50' are also arranged on a circular arc around the comb gap. However, they could also be in a common Horizontal just above the comb gap be arranged, as later with respect to Fig. 4 is clarified.
  • Fig. 2 shows one of the Fig. 1 corresponding sectional view through a second flat knitting machine 100 '.
  • the machine 100 ' differs from the machine 100 in the design of the carriage 20', which in contrast to the carriage 20 on its upper side has an opening 21, fed directly through the threads from above the yarn guides 40, 40 ', 50, 50' can be.
  • a completely open top construction of the carriage 20 ' is conceivable.
  • the supply of the threads from above has the advantage that it is possible to dispense with thread deflection devices, thread guide elements and thread tension elements which are necessary when the threads are fed laterally to the thread guides 40, 40 ', 50, 50'. Furthermore, the thread tension is reduced by reducing the friction points in such a thread feed.
  • FIG. 3a - 3d various arrangements of the two types of yarn guides 40, 40 'and 50, 50' are shown in yarn guide rails.
  • Fig. 3a is a plan view of four yarn guide rails 61, 62, 63, 64 shown, with the carriage 20 mitbewegbare yarn guide 40, 40 'are exclusively in the yarn guide rails 61 and 64.
  • the thread guides 40, 40 ' have on their upper side recesses 41, in the not shown, coupled to the carriage 20 driving devices can engage when the thread guides 40, 40' to be moved.
  • eight thread guides 40, 40 ' are arranged on the outer thread guide rails 61, 64, while only four self-contained thread guides 50, 50' are provided on the inner rails 62, 63.
  • Fig. 3b shows the example of a single yarn guide rail 60 a further possible division of the yarn guides 40, 40 ', 50, 50' with the various drive concepts. There are mounted on one of the halves of the yarn guide rail 60 only the carriage mitbewegbare yarn guide 40 and on the other half only self-sufficient yarn guide 50.
  • a yarn guide rail 60 ' is shown, are arranged in one half of both the carriage mitbewegbare yarn guide 40 and self-sufficient yarn guide 50, while only in the other half mitbewegbare yarn guide 40 are provided.
  • Fig. 3d 5 shows a single yarn guide rail 60 ", in which both the carriage co-moving yarn guides 40 and self-sufficient yarn guides 50 are arranged on the one half of the thread guides of the two drive concepts are mounted one above the other.
  • the principle can be used on one or both halves of the yarn guide rail ,
  • the Fig. 4a - 4d schematically show various possibilities of arranging the yarn guide rails on the carriage 20 with the knitting locks 30, 30 'of the flat knitting machine 100th
  • Fig. 4a the rails are arranged on an imaginary cylinder surface, so that the thread guide therein (not shown), the in Fig. 1 shown, to the center axis M inclined position take.
  • Fig. 4b however, the rails 61 'to 64' are all in one common arranged horizontally.
  • Fig. 4c shows a combination of the arrangements of the Fig. 4a and 4b ,
  • the inner yarn guide rails 62 ", 63" are arranged in a common horizontal plane and the outer yarn guide rails 61 "and 64" on an imaginary cylinder surface.
  • Fig. 4d the rails are arranged asymmetrically on an imaginary cylinder surface, so that the thread guide therein (not shown) also the in Fig. 1 shown, to the center axis M inclined position take.
  • Other variants of the asymmetrical arrangement of the yarn guide rails with respect to their number and in the Fig. 4a - 4c shown arrangements are possible.
