Description

  The present invention relates to a flat knitting machine capable of performing plating knitting using two yarn feeding carriers provided on the same yarn path track and supplying a main yarn and a splicing yarn to a knitting needle with a difference in front and back.

  Conventionally, in a flat knitting machine used mainly for knitting gloves and socks, a pair of needle beds facing each other with the mouth of the mouth alternately are used to knitting a tubular knitted fabric that becomes gloves and socks. Yes. The driving of the knitting needles arranged in parallel with each needle bed is performed by a cam mounted on a carriage that reciprocates along the needle bed, and the knitting needles advance and retreat with respect to the tooth opening. A yarn feeding carrier that feeds the knitting yarn is entrained by the carriage and supplies the knitting yarn to the knitting needle that is in the middle of moving out of the tooth mouth after having advanced into the tooth mouth. When two yarn feeding carriers, a main yarn carrier and a splicing carrier, are used to feed the main yarn with a difference in front and back so that the main yarn comes first and the splicing yarn comes back, the main yarn is knitted in a knitted tubular knitted fabric. Plating knitting is performed with the yarn on the front side and the splicing yarn on the back side.

  When the main yarn carrier and the splicing carrier are provided on the same yarn path track, the main yarn carrier precedes one of the reciprocating movements and the splicing carrier precedes the other. However, if the relative position of the yarn feeder is switched by changing the distance between the two yarn carriers in accordance with the direction of movement along the carriage, the longitudinal relationship between the main yarn and the splicing yarn can be maintained in both the reciprocating directions. (For example, refer to Patent Document 1). In Patent Document 1, the main yarn and the splicing yarn are described as a front yarn and a ground yarn, respectively. The plating knitting is described as splicing knitting. Further, the yarn path track is described as a yarn path rail.

  Patent Document 1 also discloses a configuration in which two control rods are provided in parallel with the yarn path rail. Each control rod can be displaced from the outside of the carriage so as to be in contact with or separated from the yarn path rail. One control rod carries the splicing carrier and the other control rod carries both the yarn feeding carriers to the carriage. It is possible to switch whether or not to perform. When the entraining state of the splicing carrier is released at the side end of the needle bed, the splicing carrier can be stopped and the cylindrical knitted fabric can be knitted only with the main yarn fed from the main yarn carrier. When using splicing yarn to reinforce a tubular knitted fabric, it is possible to stop the splicing carrier during knitting of parts that do not require strength, reduce the amount of splicing yarn used, and reduce manufacturing costs. it can.

Hereinafter, in the present specification, the configuration related to the main yarn and the configuration related to the splicing yarn are distinguished by attaching A and B to the same reference numerals. A description of matters common to the main yarn and the splicing yarn will be made with A and B omitted. As a condition for performing the plating knitting, when the main yarn carrier 9A and the splicing carrier 9B move in both the front side and the back side of the paper, the main yarn feeder 15Aa and the splicing yarn feeder 15Ba It is necessary to change the context. Therefore, the main yarn supplying member 15A and the splicing yarn supplying member 15B are both folded inward when contacting on the yarn supplying track 5, and the main yarn supplying port 15Aa is added. The yarn feeder 15Ba can be overtaken.
The carriage 7 is also provided with a brush 17. The knitting needle 20 provided side by side on the needle bed 2 is a latch needle, and a hook provided at the tip on the side of the tooth opening 3 is opened and closed with the spatula. The brush 17 opens a spatula from the outside. The needle bed 2 is also provided with a sinker 21 that moves back and forth between the adjacent knitting needles 20 to the tooth opening 3. The knitting needle 20 and the sinker 21 are driven by a knitting needle driving cam 22 and a sinker driving cam 23 mounted on the carriage 7, respectively.

  2A and 2B show a schematic configuration of a part related to the control rod 11, where FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a right side view. The yarn path tracks 5 and 6 are supported on both sides in the axial direction by yarn path support members 31 and 32, respectively, and are bridged above the needle bed 2 (not shown). The control rod 11 is provided between the yarn path tracks 5 and 6, and is one side of the parallelogram link so that it can be displaced toward and away from the yarn path track 5. The stationary side of the parallelogram link facing this one side is such that the base ends of the link arms 35 and 36 are swung to the link support members 33 and 34 attached to the inside of the yarn path support members 31 and 32 of the yarn path track 5. It becomes the part between the fulcrum supported movably. The control rod 11 is pin-coupled between the free ends of the link arms 35 and 36. The yarn path tracks 5 and 6 and the control rod 11 are shown in a shortened manner in the left-right direction in the figure for convenience of explanation.

  The control rod 11 is pin-coupled to the tip of the link driving member 37 in the vicinity of the right end side. The proximal end of the link driving member 37 is coupled to the distal end of the plunger of the solenoid 38. In the state shown in the figure, the solenoid 38 is OFF, the plunger protrudes by spring bias, and the control rod 11 is in a state of approaching the yarn path track 5. In this state, the leading end 12Aa of the main yarn entrainment pin 12A provided in the entrainment unit 8 protrudes toward the yarn path track 5 by urging by the spring 18A. The splicing yarn entrainment pin 12B not controlled by the control rod 11 and the tips 12Ba, 13a of the entrainment pin 13 also project toward the yarn path track 5 by urging by the springs 18B, 19. The main yarn entrainment pin 12A, the splicing entrainment pin 12B, and the entrainment pin 13 are provided with restriction pins 12Ab, 12Bb, and 13b for restricting the protruding amount, respectively. Since the bearing 14 is provided in a portion to be contacted by the control rod 11 to control the main yarn entrainment pin 12 </ b> A, the contact state is maintained smoothly even if the main yarn entrainment pin 12 </ b> A is moved along with the carriage 7. be able to. If the contact resistance can be reduced without rotating, the contact portion may be provided on a part of the main yarn entrainment pin 12A without using the bearing 14, or a contact member may be provided.

  FIG. 3 shows a state in which plating knitting is performed using the main yarn carrier 9A and the splicing carrier 9B. For example, as shown in the figure, when the main yarn carrier 9A is disposed on the left side and the splicing carrier 9B is disposed on the right side, the splicing carrier 9B precedes at the time of the right row 15R shown in FIG. At the time of 15L on the left side shown in (b), the main yarn carrier 9A precedes. However, in the positional relationship between the main yarn feeder 15Aa and the splicing yarn feeder 15Ba, the main yarn feeder 15Aa is preceded in both directions. In FIG. 3A, the main yarn carrier 9A and the splicing carrier 9B are brought into an approaching state in which a predetermined approaching distance is maintained while being entrained in the arrangement direction side of the splicing carrier 9B. In FIG. 3B, the main yarn carrier 9A and the splicing carrier 9B are brought into a separated state maintaining a predetermined separation distance while being entrained in the arrangement direction side of the main yarn carrier 9A. The leading ends 12Aa and 12Ba of both the main yarn entraining pin 12A and the splicing yarn entraining pin 12B protrude and engage with the main yarn engaging recess 9Ab and the splicing engagement recess 9Bb, respectively, and thereby the main yarn carrier 9A. In addition, both the spun yarn carrier 9B and the spun yarn carrier 9B are simultaneously entrained. Since the main yarn entrainment pin 12A and the splicing entrainment pin 12B are accommodated in the entrainment unit 8, the distance between the center lines 12Ac and 12Bc is kept constant. If the carriage 7 that travels back and forth between the main yarn carrier 9A and the accessory yarn carrier 9B is entrained, the main yarn and the accessory yarn are fed with a difference in the front and back, and the front and back needle beds are switched according to the traveling direction, A tubular knitted fabric is plated.

  FIG. 4 shows a simplified state in which the main yarn carrier 9A is stopped and the knitted fabric is knitted using only the splicing carrier 9B. When the solenoid 38 is turned on and the plunger is sucked, the link driving member 37 is also pulled and the control rod 11 is separated from the yarn path track 5. The main yarn entrainment pin 12A is in a sunk state via the bearing 14, and the state where the tip 12Aa engages with the main yarn engaging recess 9Ab is released. In the splicing carrier 9B, both the right row 15BR shown in FIG. 4 (a) and the left row 15BL shown in FIG. 4 (b) are independently carried and knitting using only the splicing yarn can be performed.

  As shown in FIG. 3 (a), the main yarn entrainment pin 12A and the splicing entrainment pin 12B have their tips 12Aa and 12Ba engaged with the main yarn engaging recess 9Ab and the splicing engagement recess 9Bb, respectively. In contact with the wall surfaces on both sides in the entrainment direction. As shown in FIG. 4 (a), when the distance between both side portions of the tips 12Aa and 12Ba is dA and dB, the distance dA of the main yarn entrainment pin 12A is equal to that of the splicing entrainment pin 12B. It is larger than the interval dB. In addition, the main yarn engaging recess 9Ab and the splicing engagement recess 9Bb have a distance sA, sB between the wall surfaces on both sides in the entrainment direction that is greater than the main yarn engaging recess 9Ab. Is bigger. As a result, the splicing entrainment pin 12B in the splicing engagement recess 9Bb is longer than the distance that the tip 12Aa of the main thread entrainment pin 12A can move in the entrainment direction in the main thread engagement recess 9Ab. The distance that the tip 12Ba of the can move in accordance with the entrainment direction becomes larger. In plating knitting, the supply of splicing yarn is performed at a position farther from the top of the main yarn than the main yarn in a range that is a shoulder on the posterior side of the top of the mountain-shaped cam with respect to the knitting needle 20 driven by the knitting needle driving cam 22. Need to do the yarn. By enlarging the moving range of the splicing carrier 9B, the splicing of the splicing yarn to the main yarn can be performed with a sufficient front-rear difference even if the entrainment direction is switched.

  FIG. 5 shows a schematic configuration of a capacitive touch panel operating glove 40 as an example of a tubular knitted fabric that can be knitted by the flat knitting machine 1. The touch panel operating glove 40 uses conductive knitting yarn as a main yarn, and is provided with plating knitting portions 41, 42, 43, 44, 45 at fingertips. Since such a glove is knitted from the tip of the finger bag, the plating knitting portions 41, 42, 43, 44, 45 are knitted at the time of knitting each finger bag, and the main yarn carrier 9A is illustrated on the way. As shown in FIG. 4, the main body is rested from the middle of the finger pouch and the body portion and the subsequent portions are knitted as the main yarn resting portion 46. The wrist portion forms a rubber thread insertion portion 47 by inserting an elastic thread. By providing the plating knitting portions 41, 42, 43, 44, 45 only in such necessary portions, the amount of expensive conductive knitting yarn used can be reduced.

  Further, since the main yarn comes out on the surface of the knitted fabric, by switching between the plating knitting and the rest by using the main yarn carrier 9A, it has various functions such as decoration of patterns and anti-slip of unevenness and the like. Knitted fabric can be knitted.
