Description of the Related Art In a knitting machine such as a sock circular knitting machine, a needle selecting device (needle selecting actuator) is used to perform a needle selecting operation of the knitting needle. To explain one example thereof, as shown in FIG. 7, a large number of needle selecting devices 3 for controlling the vertical movement of the knitting needles 2 arranged in the knitting cylinder-1 are arranged around the knitting cylinder-1. The needle device 3 is connected to the patterning controller 4, the pattern knitting procedure is sent from the patterning controller 4, and the knitting needle 2 is moved up and down to perform pattern knitting of socks. Although not shown here, a large number of needle selection jacks provided with protruding bats are arranged below the knitting needles 2, and a large number of knitting needles 2 are brought into contact with the upper portions of the jacks so that the yarn 5 Is supplied from the bobbin 6, and the needle selecting device 3 is caused to act on the needle selecting jack to move the knitting needle 2 up and down as described above to perform knit knitting of socks. Note that the needle selecting device 3 may directly act on the knitting needle 2.

The knitting needle 2 is selected by projecting it from the opening 11 of the stopper portion 10 of the support 8 and pressing or not pressing the pad as described above. The piezoelectric body 7 in the needle selecting device 3 is, for example, as shown in FIG. 6, a ceramic made by firing zirconic acid-lead titanate (P.Z.T.) or the like on both surfaces of the shim material 12. It is composed of a bimorph type piezoelectric body formed by sticking a piezoelectric element 13 made of a material. When a voltage (pulse) is applied to the piezoelectric element, distortion occurs or mechanical stress is generated. The mechanical vibration due to such a piezoelectric phenomenon is used to select the knitting needle, and as shown in the drawing, the piezoelectric body 7 is operated from the patterning controller 4 via the lead wire 14, and the finger By the operation of 9, the knitting needle 2 is selected. Although the piezoelectric driving method is described here, an electromagnetic driving method or the like is also available.

To bend the piezoelectric body 7 with the fingers 9 facing downwards,
Since the butt 16 of the needle selection jack 15 is not pressed,
The needle selection jack 15 maintains the vertical position, and as a result, the raising cam butt 17 at the lower end of the needle selection jack 15 engages with the raising cam 18, and the needle selection jack 15 and the knitting needle 2 that abuts above it are raised. The movement is effected, and as a result, the formation of the stitch by the knitting needle 2 is performed. On the other hand, as shown in FIG. 6 (A), when no voltage is applied (or when a negative pulse is applied), the piezoelectric body 7 does not bend, and therefore the butt 16 of the needle selection jack 15 is pressed. Therefore, the raising cam butt 17 at the lower end of the needle selection jack 15 is raised by the raising cam 1.
No mesh operation is given to the mesh needle 2 that is not engaged with the needle 8 and is in contact with the needle selection jack 15 above.

になる。Conventionally, in order to reduce the cost and the weight of the finger 9 in constructing the finger 9, FIG.
As shown in (A), the whole is not made of metal, but is made up of a metal portion 22 and a resin portion 23, and the metal portion 22 and the resin portion 23 having the pin insertion hole 20 are integrated, In some cases, one end of the metal portion 22 is embedded in the resin portion 23. However, when one end of the metal part 22 is embedded in the resin part 23 and integrated as described above, the metal and the resin are originally an inorganic substance and an organic substance, and therefore their adhesiveness is poor and they are separated at their interface. Tends to be easy. In particular, without using an adhesive, for example, when the metal part and the resin part are integrated with each other by resin molding, there is a tendency that they are more easily peeled off. Therefore, the metal portion 22 is provided with a hole 24 for strengthening the fixing with the resin, or as shown in FIG. 5B, a protruding portion 25 is provided at the end portion of the metal portion 22. Then, the fixing with the resin is strengthened, but in any case, the metal portion 22 falls off from the resin portion 23 and falls off. The inventors of the present invention diligently studied the reason for this, and in the conventional finger 9, the resin is interposed between the one end edge of the metal portion 22 and the pin insertion hole 20 (pin 21) inside the resin portion 23. As described above, when the needle is selected, a large impact is applied to the tip of the metal part 22 in the horizontal direction, and a large load is applied to the tip of the metal part 22 in the vertical direction. The load affects the resin interposed between the one end edge of the metal part 22 and the pin insertion hole 20 (pin 21), causing a crack in the resin part 23 in contact with the one end edge of the metal part 22. It has been found that the metal portion 22 falls off from the resin portion 23 and causes the metal portion 22 to fall off. Further, in the conventional finger, the pin insertion hole 20 gradually changes due to long-term use.
The diameter X of the metal part 22 may increase, which may adversely affect the device.
It was also found that it was caused by the wide interposition of resin between 1). In other words, in the above-mentioned conventional finger, the resin corresponding to the soft gum is hit by a hard metal, the gum is broken, and the metal part falls out, which further adversely affects the pin insertion hole 20 in the rear part. become.

着用穴が広がってしまうようなことを回避できる。In the present invention, even if the finger embeds the metal part in the resin part and integrates them, the end part of the metal part is in contact with the pin inserted in the pin insertion hole of the resin part. Therefore, even if an impact load is applied to the tip of the metal part during needle selection, the pin receives the impact and load. Therefore, in the conventional finger, resin is interposed between the end of the metal part and the pin. However, impact and load are concentrated on the resin portion to cause a crack, and eventually the metal portion in the resin has fallen off from the resin portion, but this can be prevented. In addition, the pin receives and relieves shocks and loads,
It is also possible to avoid the influence on the pin insertion hole and to prevent the pin insertion hole from expanding as in the conventional case.

The needle selecting device (needle selecting actuator) according to the present invention can be applied to various knitting machines such as sock knitting machines. In the circular knitting machine, the needle plate, that is, the knitting cylinder, rotates with respect to the machine base of the circular knitting machine, and the needle selection device is fixedly provided on the machine base of the circular knitting machine. When the needle selecting device according to the present invention is used in a circular knitting machine, when the individual fingers of the needle selecting device fixed to the machine stand are activated, the knitting needle finger butt in the rotating knitting cylinder is used. Alternatively, it is necessary that the knitting needle is configured so as to contact the lower end of the knitting needle. On the other hand, the needle selection device (needle selection actuator) according to the present invention,
It can also be used for flat knitting machines. In a flat knitting machine, a needle plate is fixedly provided on a machine base of the flat knitting machine, and a carriage including a needle selecting device and a yarn supplying device slides along the needle plate to knit a pattern knitted fabric. Therefore, when the carriage slides, the tip portion of the finger of the needle selecting device operates and contacts the finger butt of the knitting needle in the fixed needle plate or the lower end of the knitting needle. It must be configured to abut the finger butt of the jack that is placed.
