The yarn feeder for a flat knitting machine according to the present invention can solve the problem that the yarn feeding position is erroneous by changing the yarn feeding position in the process of knitting using the flat knitting machine.

It is a figure showing roughly the structure of one embodiment of a flat knitting machine concerning the present invention. BRIEF DESCRIPTION OF THE DRAWINGS It is the figure 1 which shows schematically the structure of the yarn feeding mechanism in one Embodiment of the yarn feeder for flat knitting machines which concerns on this invention. FIG. 3 is a second diagram schematically illustrating a structure of a yarn feeding mechanism in an embodiment of a yarn feeder for a flat knitting machine according to the present invention. It is a figure which shows roughly the structure of one Example of the yarn feeding mechanism in one Embodiment of the yarn feeder for flat knitting machines which concerns on this invention.

  Hereinafter, the yarn feeder for a flat knitting machine according to the present invention will be described in detail with reference to related drawings.

  As shown in FIGS. 1 to 4, the present invention provides a weft feeder 20 for a flat knitting machine in which the yarn feeding position can be changed. The weft feeder 20 for a flat knitting machine is used in an area set between two needle beds 11 and 12 in the flat knitting machine 100. The weft knitting machine yarn feeder 20 according to the present invention includes a drive mechanism 21 and a yarn feed mechanism 22, and the drive mechanism 21 includes a motor 23 and a drive plate 24 connected to the motor 23. . The motor 23 is controlled by receiving an electronic signal when the knitting conditions of the flat knitting machine 100 are changed. The drive plate 24 moves linearly in conjunction with the motor 23.

  As shown in FIGS. 2 to 4, the yarn feeding mechanism 22 includes a transition plate 25 connected to the drive plate 24 and a yarn feeding arm 26 assembled to the transition plate 25. The transition plate 25 is configured to move according to the drive plate 24. In one embodiment of the weft feeder for a flat knitting machine according to the present invention, the drive plate 24 includes a protrusion 241 provided at the end of the transition plate and protruding toward the transition plate 25. The mounting rail 257 for providing the portion 241 is provided, and the mounting rail 257 does not need to be provided with a portion having undulations, and may be any as long as the protruding portion 241 interlocks the transition plate 25.

  The transition plate 25 includes guide holes 251 other than the circular holes. In one embodiment of the yarn feeder for a flat knitting machine according to the present invention, the guide hole 251 includes two inclined surfaces 252 and 253 provided to face each other, and the two inclined surfaces 252 and 253 are supplied to the flat knitting machine. It is arranged on the movement locus of the thread device 20. The guide hole 251 may be trapezoidal. The yarn supplying arm 26 includes a guide post 261 provided in the guide hole 251, and the guide post 261 is set to have a length so as to contact at least the guide hole 251 of the transition plate 25. The yarn feeding arm 26 includes a yarn feeding end 262 facing one of the needle beds 11 (or 12).

  The structure of the yarn feeder 20 for a flat knitting machine according to the present invention will be specifically described with reference to FIGS. FIG. 3 shows an initial state of the weft feeder 20 for a flat knitting machine, and FIG. 4 shows a state after adjustment. In the initial state, the operation starts when the drive mechanism 21 receives an electronic signal. The drive plate 24 is interlocked and moved in the propulsion stroke (see 240 in FIG. 3), and the drive plate 24 is moved in the displacement stroke 254 in conjunction with the transition plate 25. The movement in the displacement stroke 254 is also a linear movement. Further, when the transition plate 25 moves in the displacement stroke 254, if the guide hole 251 is displaced according to the transition plate 25, the guide post 261 changes its position in the guide hole 251 (see FIG. 4), and the yarn feeding The arm 26 is displaced when the guide post 261 changes its position (see the moving direction 291 shown in FIG. 4), and by changing the yarn supplying position with respect to the needle bed 11 (or 12) of the yarn supplying end 262, The yarn feeding position of the flat knitting machine yarn feeder 20 is changed.
