Definitions

  • the present invention relates to a self-running yarn feeder, i.e. a yarn feeder that runs independently from a carriage, installed in a flatbed knitting machine capable of feeding yarns for knitted fabric knitting to knitting needles arranged in line in needle beds.
  • a flatbed knitting machine is provided with a large number of knitting needles arranged in line along a needle bed gap and the knitting needles are driven so as to advance to and retract from the needle bed gap in order to knit a knitted fabric.
  • a general flatbed knitting machine is provided with a plurality of running paths bridged above the needle bed gap and a plurality of yarn feeders running on the running paths. Yarn feeder ports for feeding knitting yarns to the knitting needles are provided at the lower ends of the yarn feeders (for example, see Fig. 1 of Patent Literature 1).
  • the plurality of yarn feeders are configured so as to be capable of moving the yarn feeder ports in the up-down direction (for example, see Patent Literatures 1 and 2).
  • Yarn feeding positions at which the yarn feeders feed the knitting yarns to the knitting needles are positions at which the yarn feeder ports are descended, and the knitting yarns are fed to the knitting needles under equivalent conditions by making them close to each other. Collision and interference between the yarn feeder ports are prevented at standby positions at which the knitting yarns are not fed to the knitting needles and the yarn feeder ports are ascended.
  • the yarn feeders are entrained by a carriage running along needle beds in some cases, and in other cases they self-run independently from the running of the carriage.
  • the yarn feeder ports are moved in the up-down direction by entraining pins that are engaged for entraining (for example, see Figs. 2 to 10 of Patent Literature 1).
  • sliding resistance against the running of the yarn feeders is used for the up-down movement of the yarn feeder ports (see, Figs 11 and 12 of Patent Literature 1 and a paragraph 0058 of Patent Literature 2).
  • Prior art document US 4 738 124 A discloses a yarn feeder slide proposed for intarsia knitting on a flat knitting machine and provided with a braking device which has brake shoes projecting sideways on pivoted levers and which extend into a special longitudinal slot of the associated yarn feeder rail and can be jammed therein.
  • Two control regions for the braking device or for a moveable yarn feeder arm are provided and are spaced from one another in the direction of displacement of the yarn feeder slide so that the yarn feeder driving member located on the cam carriage of the flat knitting machine can be selectively lowered into both control regions of the yarn.
  • the sliding resistance for the self-running yarn feeders i.e. they are not driven by a carriage, that is used for the up-down movement of the yarn feeder ports, increases load for driving to run.
  • large driving force is required for running, and driving parts are caused to grow in size.
  • Large sliding resistance implicates large friction between the yarn feeders and railways along which they are caused to run, and there is a concern over abrasion of the railways.
  • small sliding resistance might cause uncertainty for switching the up-down movement of the yarn feeder ports reliably.
  • An object of the present invention is to provide a yarn feeder for a flatbed knitting machine, which is capable of self-running, i.e. running independently from a carriage, while reducing sliding resistance.
  • the present invention is a yarn feeder for a flatbed knitting machine provided with:
  • the sliding resistance of the brake member against the running path is increased to be larger than resistance received by movement of the brake member relative to the base body, so that a braking state is made in which the brake member stops relative to the running path even when the base body runs relative to the running path,
  • said pressing part and said pressure receiving part slide relative to each other in said functioning range.
  • said elevation mechanism comprises:
  • said elevation mechanism comprises:
  • said pressing part and said pressure receiving part oscillate about an oscillation shaft installed on said base body in said functioning range.
  • said base body has rollers running on a rail installed on said running path, and said sliding resistance is generated by the rail and said braking surface of said brake member.
  • a brake member is capable of moving relatively within a functioning range which is previously set to a base body.
  • the brake member is made into a state of being moved to either of both end portions of the functioning range with the movement thereof relative to the base body.
  • the base body entrains the brake member and the yarn feeder can self-run while reducing sliding resistance against a running path. If the base body is stopped running, moved a little in an opposite direction, and then stopped, the brake member is moved to an intermediate position of the functioning range with the movement thereof relative to the base body to become a braking state.
  • This relative movement enables an elevation mechanism to ascend the yarn feeder port to a standby position reliably.
  • the ascended yarn feeder port can be caused to stand by in a state in which collision and interference with other yarn feeder ports are prevented and the sliding resistance against the running path is increased by the brake member.
  • the state can be shifted by sliding between a pressing part of the base body and a pressure receiving part of the brake member.
  • the feeder rod runs together with the base body on which a guiding part is installed, so that the running position of the yarn feeder port can be caused to correspond to the base body.
  • the relative movement of the base body and the brake member causes the pressing part of the base body to be moved to the pressure receiving part from the end portion of the brake member while passing through a shift part.
  • the guiding part for guiding the up-down movement of the feeder rod is installed on the brake member, so that the feeder rod runs together with the brake member.
  • the feeder rod When the base body is started running in a state in which the brake member is stopped in the braking state against the running path, the feeder rod is descended with the elevation mechanism before the brake member is relatively moved to the end portion of the functioning range and is entrained.
  • the feeder rod can be caused to run so as to be entrained by the base body together with the brake member after the yarn feeder port is descended to the yarn feeding position.
  • the brake member can be shifted between the braking state and the braking-released state by relative movement with oscillation about an oscillation shaft installed on the base body.
  • a movement range of the brake member is restricted to a range about the oscillation shaft and a space necessary for the functioning range is reduced, thereby it is performed to reduce the mechanism in size.
  • rollers and the brake member share a rail of the running path and the braking part of the brake member is caused to directly work on the rail, thereby it is performed to increase the sliding resistance.
  • a schematic configuration and operations of a yarn feeder (hereinafter, abbreviated as YF in some cases) 4 as an example 1 of the present invention will be described with reference to Figs. 1 to 6 .
  • Figs. 7 , 8 illustrates schematic configuration of an example 2,3 of the present invention respectively.

  • a mechanism (not illustrated) to drive the belts 6, 7 is installed on an end portion of the running path 5 in the longitudinal direction.
  • wires or chains may also be used.

  • the upper rollers 11b are supported by a lever 11c and are compressed to an upper rail 5b by urging of a wire spring 12.
  • the lower rollers 11a and the upper rollers 11b respectively roll on a lower rail 5a and the upper rail 5b.
  • the brake member 3 is movable in the up-down direction and makes pressure contact with the lower rail 5a when moved downward to increase sliding resistance between the base body 1 and the running path 5.
  • the feeder rod 2 droops from the base body 1 and is movable in the up-down direction along an alternate long and short dash line 2a relatively to the base body 1 by an elevation mechanism 4a, which will be described later.

  • An upper portion of the yarn feeding chip 20 is held by holding parts 2b at the lower end of the feeder rod 2.
  • the feeder rod 2 forms a driven part 21 in an upper portion thereof.
  • the up-down movement of the driven part 21 is guided by guiding grooves 10a provided in the supporting plate 10.
  • the feeder rod 2 and the driven part 21 are arranged on the front surface side of the base body 1 and the supporting plate 10 is arranged on the further front surface side of the base body 1 relative to the driven part 21.
  • Fig. 2 is a simplified rear view of Fig. 1 illustrating (a) a state in which the yarn feeder port 20a of the feeder rod 2 is descended to the yarn feeding position 9 and (b) a state in which the yarn feeder port 20a of the feeder rod 2 is ascended to a standby position.
  • the YF 4 feeds the knitting yarn to the knitting needle from the yarn feeder port 20a descended to the yarn feeding position 9 while running to one side of the running path 5, for example, to the right side in Fig. 2(a) by being towed with the belts 6, 7. On the occasion when making the YF 4 stop to run, it is stopped to tow to the one side with the belts 6, 7.
  • the YF 4 restarts running in the state in which the yarn feeder port 20a is descended to the yarn feeding position 9.
  • the towing is stopped after pulling the belts 6, 7 a little to the other side and causing the base body 1 to run leftward to shift the state to a braking state illustrated in Fig. 2(b) .
  • the YF 4 is caused to continuously run while the running direction of the YF 4 is reversed from the one direction to the other direction, the towing direction with the belts 6, 7 is switched from the one direction to the other direction.
  • the base body 1 and the brake member 3 are once stopped, the base body 1 is towed to the other side by being towed to the other side by the belts 6, 7 and the brake member 3 is entrained to the other side.
  • the yarn feeder port 20a is once ascended to the standby position from the yarn feeding position 9, and then, is descended to the yarn feeding position 9 again.
  • the above-described operations of the YF 4 towed by the belts 6, 7 are performed in the same manner in the example 2 and the example 3, which will be described later.
  • the brake member 3 is supported on the base body 1 so as to be relatively movable in a predetermined functioning range in the running direction of the YF 4.
  • the functioning range is determined by function long holes 30 provided in the brake member 3.

  • the lower ends of the brake member 3 function as braking surfaces 31 facing the lower rail 5a of the running path 5.
  • the pressure receiving parts 30b are formed from the lower end of the brake member 3 , so as to be higher than the bottom surfaces of the one end portions 30a and the other end portions 30c.

  • the pressure receiving parts 30b receive downward pressures from the rollers 14 at the intermediate positions of the functioning range.
  • the braking surfaces 31 of the brake member 3 are compressed to the lower rail 5a of the running path 5, so that the sliding resistances against the running path 5 are increased.
  • the YF 4 ascends the yarn feeder port 20a to the standby position and stops in the braking state. Even in the state in which the rollers 14 press downward the pressure receiving parts 30b, the resistances of the rollers 14 and the brake member 3 against the relative movement are not so large, so that the braking state can be easily released by towing with the belts 6, 7.

  • An elevation mechanism 4a is formed across the feeder rod 2, the base body 1, and brake member 3, and the elevation mechanism 4a converts the relative movement of the base body 1 to the brake member 3 into up-down movement of the feeder rod 2 and ascends the feeder rod 2 in the braking state of the brake member 3.
  • the elevation mechanism 4a can move the follower 22 to the high position at the center of the elevation cam 32 to ascend the feeder rod 2 reliably by the movement of the base body 1 relative to the brake member 3 stopping in the braking state relative to the running path 5.

    wobei, wenn der Drückteil (14, 65) den Druckempfangsteil (30b; 63b) drückt, die Bremsfläche (31; 63b) zu dem Laufpfad (5) gedrückt wird,
    dadurch gekennzeichnet, dass:
    der Gleitwiderstand des Bremsglieds (3, 53, 63) gegen den Laufpfad (5) erhöht wird, sodass er größer als der durch die Bewegung des Bremsglieds (3, 53, 63) relativ zu dem Basiskörper (1, 51) empfangene Widerstand ist, sodass ein Bremszustand hergestellt wird, in dem das Bremsglied (3, 53, 63) auch dann relativ zu dem Laufpfad (5) stoppt, wenn der Basiskörper (1, 51) relativ zu dem Laufpfad (5) läuft,
    wenn sich das Bremsglied (3, 53, 63) zu einem der beiden Endteile (30a, 30c; 63a, 63c) des Funktionsbereichs mit einer Bewegung relativ zu dem Basiskörper (1, 51) bewegt, der Druck von dem Drückteil (14, 65) reduziert wird und der Gleitwiderstand der Bremsfläche (31; 63b) auf dem Laufpfad (5) reduziert wird, um den Bremszustand aufzuheben, sodass das Bremsglied (3, 53, 63) durch den Basiskörper (1, 51) mitgenommen wird, um zu laufen, und
    ein Hubmechanismus (4a, 50a, 60a), der eine relative Bewegung zwischen dem Basiskörper (1, 51) und dem Bremsglied (3, 53, 63) in eine Oben-Unten-Bewegung der Führerstange (2, 52, 62) umsetzt und die Führerstange (2, 52, 62) in den Bremszustand des Bremsglieds (3, 53, 63) hebt, zwischen der Führerstange (2, 52, 62), dem Basiskörper (1, 51) und dem Bremsglied (3, 53, 63) ausgebildet ist.
  2. Fadenführer (4, 50) für eine Flachstrickmaschine nach Anspruch 1, wobei der Drückteil (14) und der Druckempfangsteil (30b) relativ zueinander in dem Funktionsbereich gleiten.
  3. Fadenführer (4) für eine Flachstrickmaschine nach Anspruch 1 oder 2, wobei der Hubmechanismus (4a) umfasst:
    einen Führungsteil (1b), der an dem Basiskörper (1) installiert ist und die Oben-Unten-Bewegung der Führerstange (2) führt,
    eine Nockenplatte (32), die an dem Bremsglied (3) installiert ist und die Oben-Unten-Bewegung der Führerstange (2) antreibt, und
    einen angetriebenen Teil (21), der an der Führerstange (2) installiert ist und durch die Nockenplatte (32) angetrieben wird.
  4. Fadenführer (4, 50, 60) für eine Flachstrickmaschine nach einem der Ansprüche 1 bis 3, wobei:
    das Bremsglied (3, 63) eine derartige Form aufweist, dass ein Druck von dem Drückteil (31, 65) an dem Druckempfangsteil (30b, 63b) und eher nicht an den beiden Endteilen (30a, 30c, 63a, 63c) erhöht wird, und
    das Bremsglied (3, 63) Verschiebungsteile (30d, 30e; 63d, 63e) umfasst, auf die der Druck allmählich erhöht wird, wenn sie sich zu dem Druckempfangsteil (30b, 63b) von den beiden Endteilen (30d, 30e; 63d, 63e), an denen der Druck niedriger ist, bewegen.
  5. Fadenführer (50) für eine Flachstrickmaschine nach einem der Ansprüche 1, 2 und 4, wobei der Hubmechanismus (50a) umfasst:
    einen Führungsteil (54) und eine Nockenplatte (32) jeweils zum Führen und Antreiben der Oben-Unten-Bewegung der Führerstange (52), die an dem Bremsglied (53) installiert sind, und
    einen angetriebenen Arm (56), der an der Führerstange (52) installiert ist und durch die Nockenplatte (32) angetrieben wird.
  6. Fadenführer (60) für eine Flachstrickmaschine nach Anspruch 1, wobei der Drückteil (65) und der Druckempfangsteil (63b) um eine Oszillationswelle (65), die an dem Basiskörper in dem Funktionsbereich installiert ist, oszillieren.
  7. Fadenführer (4, 50, 60) für eine Flachstrickmaschine nach einem der Ansprüche 1 bis 6, wobei:
    der Basiskörper (1, 51) Rollen (11a, 11b) aufweist, die auf einer an dem Laufpfad (5) installierten Schiene (5a, 5b) laufen, und
    der Gleitwiderstand durch die Schiene und die Bremsfläche (31; 63b) des Bremsglieds (3, 53, 63) erzeugt wird.
