Definitions

  • the present invention relates to a flatbed knitting machine provided with compound needles, each compound needle is formed by combining a needle body and a slider, and knits a fabric by opening and closing a hook of the needle body by a tongue of the slider, and a control method for the slider of the flatbed knitting machine.
  • Figs. 7 simplistically show a state in which a fabric is knitted by a flatbed knitting machine 1.
  • Needle grooves 5 are formed in each of a pair of needle beds 3,4 which are opposed to each other with respect to a needle bed gap 2.
  • Each of the needle grooves 5 is formed in an inclined manner such that one side thereof close to the needle bed gap 2 is positioned higher than the other side thereof away from the needle bed gap 2. Further, the needle grooves 5 are arranged in the direction perpendicular to the sheet on which the figures are drawn.
  • a needle plate and a sinker 5a are provided between the needle grooves 5, amd in the vicinity of a head end of the sinker 5a at the needle bed gap side, a wire 6 as a top tooth penetrates in the direction perpendicular to the sheet of the figure.
  • a yarn feeder 7 moves in the direction perpendicular to the sheet surface on which the figure is drawn, and feeds a knitting yarn 8 from a yarn feeder port 7a.
  • fig. 7(a) shows a case in which a plain knit fabric 9 and the like is knitted by using only the needle bed 3.
  • fig. 7(b) shows a case in which a rib knit fabric 10 and the like is knitted by using both of the needle beds 3, 4, respectively.
  • a compound needle 11 is put in as a knitting needle.
  • a needle body 12 is combined with a slider 13.
  • a slider groove 12b is also formed on the needle body 12 which has a hook 12a at a head end thereof.
  • the slider 13 is partially put in the slider groove 12b and makes aslide move with respect to the needle body 12 so as to open and close a hook mouth of the hook 12a by a tongue 13a which is formed in a head end of the slider 13.
  • the hook 12a is advanced into the needle bed gap 2 only from one needle bed 3, and then, when the hook 12a is withdrawn into the needle bed 3, the knitting yarn 8, which is fed from the yarn feeder port 7a and passes within a range through which the hook mouth of the hook 12a passes, is caught in the hook 12a.
  • An old stitch 9a is cleared from inside of the hook 12a when the hook 12a is advanced into the needle bed gap 2, moves onto the tongue 13a of the slider 13 waiting on the needle bed 3 side, and is retained therein.
  • the hooks 12a are, for example, alternately advanced into the needle bed gap 2 from both needle beds 3, 4, to thereby catch the knitting yarn 8, and then an old stitch 10a moves onto the tongue 13a after being cleared from the hooks 12a.
  • the hook 12a While retaining the old stitch 9a or 10a on the tongue 13a, the hook 12a is further withdrawn into the needle bed 3, 4, the hook mouth of the hook 12a is closed by the tongue 13a, and then the needle body 12 and the slider 13 are further withdrawn into the needle bed 3,4, so that as a result, the old stitch 9a or 10a is knocked over to form the plain knit fabric 9 or the rib knit fabric 10 and hangs down in the needle bed gap 2, and a new stitch is formed in the closed hook 12a.
  • the advancement and withdrawal of the needle body 12 or the slider 13 into and from the needle bed gap 2 is driven by a cam mechanism which is mounted on a carriage which runs back and forth in the direction perpendicular to the sheet surface on which the figure is drawn, and arranged so as to face each of the needle beds 3, 4.
  • the yarn feeder 7 moves in synchronization with the carriage.
  • the plain knit fabric 9 or the rib knit fabric 10 is knitted by repeating such operations of the carriage and the yarn feeder 7.

  • the rib knit fabric 10 which is knitted by using the needle beds 3, 4 at both sides of the needle bed gap 2 hangs down near the center of the needle bed gap 2.
  • the knitting yarn 8 has moved out of the knitting width from an end stitch at a termination side of the knitting and crosses over to the yarn feeder 7 so as to serve as a cross-over yarn.
  • This cross-over yarn crosses over to the yarn feeder 7, becomes the knitting yarn 8 that is fed when the carriage is inverted so that the termination side in an old course becomes a starting point side in a new course and a first stitch of the new course is formed.
  • the cross-over yarn which crosses over to the yarn feeder 7, is in a state of being folded back from the old stitch 9a or 10a retained on the tongue 13a, and passes through the position closer to the needle bed 3 in the plain knit fabric 9 or passes through the position closer to the center of the needle bed gap 2 in the rib knit fabric 10.
  • Such a difference in the position through which the knitting yarn 8 passes arises not only for end stitches of the knitting width but also for end portions of a section in which intarsia knitting is performed within the knitting width, or when a new stitch is knitted by performing a kick back of the yarn feeder 7.
  • the old stitch 10a is retained in the vicinity of a head end position of the tongue 13a.
  • the old stitch 10a may drop into the hook 12a again depending on conditions such as high knitting speed.
  • the knitting yarn 8 may get caught in the tongue 13a which has been advanced toward the needle bed gap 2, thereby making it difficult to catch the knitting yarn 8 in the hook 12a.

Procédé pour contrôler un coulisseau (13) d'une machine à tricoter à plat (21), la machine à tricoter à plat (21) comportant au moins deux fontures (3, 4) opposées entre elles en ce qui concerne un intervalle entre fontures (2), dans chaque fonture (3, 4) des gorges d'aiguilles (5) agencées côte à côte selon une ligne, la machine à tricoter à plat (21) comportant des aiguilles compound (11), chacune d'elles étant prévue dans une des gorges d'aiguille (5) et formée en combinant un corps d'aiguille (12), comportant un crochet (12a) au niveau d'une extrémité de tête, et un coulisseau (13) ayant un mouvement coulissant par rapport au corps d'aiguille (12) et comportant une languette (13a) au niveau d'une extrémité de tête, la languette (13a) ouvrant et fermant le crochet (12a), de sorte qu'une crosse de commande d'aiguille (22) du corps d'aiguille (12) et une crosse de commande de coulisseau (23) du coulisseau (13) sont entraînées par un système de cames (30) de façon à attraper un fil à tricoter (8) dans le crochet (12a) lorsque le crochet (12a) est avancé dans l'intervalle entre fontures (2) puis retiré dans la fonture (3, 4), et la machine à tricoter à plat est munie d'une came (41) dans une section correspondant à une partie se trouvant dans la trajectoire (23t) d'une route de tricotage à travers laquelle passe la crosse de commande de coulisseau (23) dans une opération de tricotage, au moment d'attraper le fil à tricoter (8) dans le crochet (12a),
    caractérisé par
    un contrôle de la position du coulisseau (13) en agissant sur la crosse de commande de coulisseau (23) pour le faire avancer dans une position haute dans une direction rentrant dans l'intervalle entre fontures (2) pour rendre dure une maille ancienne (9a, 10a) retenue sur la languette (13a) pour qu'elle tombe dans le crochet (12a), ou une position basse dans une direction de retrait par rapport à l'intervalle entre fontures (2) pour rendre dur le fil à tricoter (8) fourni par un distributeur de fil (7) pour qu'il soit attrapé sur la languette (13a).
  6. Procédé pour contrôler un coulisseau (13) d'une machine à tricoter à plat (21) selon la revendication 5, dans lequel
    le changement par le contrôle de la position du coulisseau (13) est réalisé en fonction d'un état de sélection d'aiguille de telle façon que l'action sur la crosse de commande de coulisseau (23) par l'intermédiaire de la came (41) varie en fonction du fait que la position à laquelle se trouve le fil à tricoter (8) s'étendant à partir du distributeur de fil (7) jusqu'à un tissu tricoté (9, 10), est plus proche de la fonture (3, 4) dans laquelle est prévue l'aiguille compound (11) qui attrape le fil à tricoter (8) que d'une position intermédiaire de l'intervalle entre fontures (2), pour modifier en fonction de cela la position du coulisseau (13) pour passer dans la position basse ou la position haute.
