Definitions

  • the invention relates to a flat knitting machine with at least two needle beds, with at least one carriage equipped with knitting cams that can be moved over the needle beds, and a thread feed device with thread guide rails arranged above the needle beds, in which thread guides are arranged that can be moved by the at least one carriage.
  • Such flat knitting machines correspond to the state of the art that has been common for many years. However, ever higher demands are being placed on the pattern and design of knitted fabrics. This also increases the demands on the machines for producing such knitted fabrics, in particular intarsia knitted fabrics or plated knitted fabrics.
  • Self-sufficiently driven thread guides have already been used, which can take up any desired position in the needle space of a knitting machine during the knitting process.
  • Devices for inserting threads have also become known, which can feed threads to the knitting needles above and separately from the actual thread guides.
  • U.S. 5,615,562 A discloses a special thread guide that is driven independently and can perform movements in and transverse to the direction of the carriage.
  • the object of the present invention is to provide a flat knitting machine with which conventional knitted fabrics and knitted fabrics with complex patterns or plated knitted fabrics can be produced 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 along by the carriage by suitable means, and thread guides driven independently of the carriage, with both thread feed concepts retaining their full functionality. This is advantageous over some of the thread feeding devices mentioned above which represent a compromise between the two types of thread feeding.
  • Each self-sufficient thread guide can expediently have its own drive device in order to be able to fully exploit the variability of the thread feed. However, it is also possible to provide two or more self-sufficient thread guides with a common drive device.
  • the autonomous thread guide or thread guides are arranged in one or more separate thread guide rails so that they can be displaced longitudinally. They can be moved in these rails over the entire length without having to take into account possible collisions with a yarn guide moved by the carriage.
  • the thread guide rails with thread guides that can be moved along by the carriage and the thread guide rails with self-sufficient thread guides are arranged alternately parallel to one another above the needle beds in order to be able to create similar conditions for the thread feed to the needles for both thread guide types.
  • thread guides are arranged in each case in the thread guide rails for autonomous thread guides.
  • Eight thread guides can be arranged in the thread guide rails for thread guides that can be moved along with the carriage.
  • the autonomous thread guides and the thread guides that can be moved along with the carriage are arranged in common thread guide rails. Fewer rails are then required than in an embodiment with separate rails for the autonomous thread guides.
  • the autonomous thread guides and the thread guides that can be moved along with the carriage are arranged together in at least one of the halves of the thread guide rail.
  • a further alternative is that at least one half of one or more thread guide rails has two tracks arranged one above the other, with one or more autonomous thread guides being arranged in one of the tracks and one or more thread guides moved by the carriage being arranged in the other track.
  • the thread guide rails are at least partially arranged in a common horizontal plane above the needle beds.
  • the threads can be fed in from the side, as is generally customary.
  • the flat knitting machine can also have a carriage which has an opening on the upper side through which threads can be fed to the thread guides and further to the needles in the needle beds.
  • 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 can be moved over the needle beds 10, 10', to which front and rear knitting cams 30, 30' are attached, with which knitting tools not shown here, which are mounted in the needle beds 10, 10', can be controlled and moved .
  • the two needle beds enclose a comb gap KS between them. This is located on a central axis M of the flat knitting machine 100.
  • Thread guides 40, 40' and 50, 50' are attached above the needle beds 10, 10' and the comb gap KS.
  • the outer thread guides 40, 40' which are further away from the machine axis M, are conventional thread guides, which can be moved along with the carriage 20 via driver devices (not shown here).
  • the inner thread guides 50, 50' are self-sufficiently driven thread guides, which can thus be moved by the carriage 20 independently. An up and down movement of the thread guide arm or the thread guide nut is also possible.
  • the arrangement of the thread guides 40, 40' and 50, 50' in relation to the stitch axis M is merely an example.
  • the thread guides 50, 50' could also be arranged on the outside or alternately with the thread guides 40, 40'.
  • the thread guides 40, 40' and 50, 50' are also arranged on a circular arc around the comb gap. However, they could also be arranged in a common horizontal plane just above the comb gap, as later with reference to FIG 4 is made clear.
  • FIG. 2 shows one of the 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, has an opening 21 on its upper side through which the threads are fed directly from above to the thread guides 40, 40', 50, 50' can become.
  • a construction of the carriage 20' that is completely open at the top is also conceivable. Feeding the threads from above has the advantage that thread deflection devices, thread guide elements and thread tensioning elements can be dispensed with, which are necessary when the threads are fed to the thread guides 40, 40', 50, 50' from the side. Furthermore, the thread tension is reduced by reducing the friction points with such a thread feed.
  • FIGs 3a - 3d are different arrangements of the two types of yarn guides 40, 40 'and 50, 50' shown in yarn guide rails.
  • Figure 3a a top view of four thread guide rails 61, 62, 63, 64 is shown, with thread guides 40, 40' that can be moved along with the carriage 20 being located exclusively in the thread guide rails 61 and 64. Separate thread guide rails 62, 63 are provided for the autonomous thread guides 50, 50'.
  • the thread guides 40, 40' have recesses 41 on their upper side, into which driver devices (not shown) coupled to the carriage 20 can engage when the thread guides 40, 40' are to be moved.
  • eight thread guides 40, 40' are arranged on the outer thread guide rails 61, 64, while only four independent thread guides 50, 50' are provided on the inner rails 62, 63.
  • FIG. 3b Using the example of a single thread guide rail 60, FIG. On one of the halves of the thread guide rail 60 only thread guides 40 which can be moved along by the carriage are attached and on the other half only self-sufficient thread guides 50 are attached.
  • a thread guide rail 60' is shown in which both thread guides 40 that can be moved by the carriage and autonomous thread guides 50 are arranged on one half, while thread guides 40 that can only be moved by the carriage are provided in the other half.
  • a single thread guide rail 60" is shown, in which both thread guides 40, which can be moved by the carriage, and autonomous thread guides 50 are arranged on one half.
  • the thread guides of the two drive concepts are mounted one above the other here. The principle can be used on one or both halves of the thread guide rail .
  • Figures 4a - 4d show schematically different possibilities for the arrangement of the yarn guide rails above the carriage 20 with the knitting cams 30, 30' of the flat knitting machine 100.
  • the rails are arranged on an imaginary cylinder surface, so that the thread guides (not shown) located therein 1 shown, take the central axis M toward inclined position.
  • the rails 61' to 64' are all arranged in a common horizontal plane.
  • Figure 4c shows a combination of the arrangements from the Figures 4a and 4b .
  • the inner thread guide rails 62", 63" are arranged in a common horizontal plane and the outer thread guide rails 61" and 64" are arranged on an imaginary cylindrical surface.
  • the rails are arranged asymmetrically on an imaginary cylinder surface, so that the thread guides (not shown) located therein also have the 1 shown, take the central axis M toward inclined position.
  • Other variants of the asymmetrical arrangement of the yarn guide rails in terms of their number and in the Figures 4a - 4c arrangements shown are possible.
