2. Description of the Related Art In a sock circular knitting machine, a jack having a finger bat is fitted into a number of grooves on the outer periphery of a knitting machine cylinder by vertically moving a knitting needle. A knitting needle of a circular knitting machine is selectively pressed by a finger of a knitting machine needle selecting device provided around a knitting machine rotating cylinder.

An example of the needle selecting operation of the knitting needle of the knitting machine will be described with reference to FIG.
A finger 4 is attached to an end of a piezoelectric body 3 having a piezoelectric element 2 attached to both sides of a metal plate 1. A controller (electronic patterning control device) (not shown) attaches the finger 4 to the piezoelectric element 2 of the piezoelectric body 3. A pulse is applied through the conductor R. That is, to explain an example of the needle selection operation,
FIG. 8A shows a state where no pulse is applied to the piezoelectric element 2 of the piezoelectric body 3, and FIG. 8B shows a state where a pulse is applied to the piezoelectric element 2 of the piezoelectric body 3 and the piezoelectric body 3 is bent. It shows the state that it was turned on. In the state shown in FIG. 8A, the finger bat 6 of the jack 5 (or the knitting needle itself) comes into contact with the tip of the finger 4 and pushes the jack 5 rightward. As a result, the raising cam butt 7 at the lower end of the jack 5 cannot engage with the raising cam 8, and as a result, the knitting needle (not shown) abutting above the jack 5 performs a lifting movement. No stitches are formed with this knitting needle. On the other hand, in the state shown in FIG. 8B, since the finger 4 does not enter the movement path of the finger bat 6 of the jack 5 due to the bending of the piezoelectric body 3, the jack 5 maintains the vertical position, and as a result, the jack 5 is raised. The cam butt 6 engages with the raising cam 8 to push up the jack 5 upward, so that the knitting needle contacting above the jack 5 is given knitting operation. FIG. 8C is a perspective view of the jack 5.

The response speed in the needle selection operation can be further improved as compared with the conventional example in which the through hole 40 is not provided. On the other hand, in the needle selecting device, a finger topper is provided to perform a stopper function of the finger. FIG. 6B shows a topper 9 for the finger 4. The fin gas topper 9 is provided with two fin gas topper openings 9A and 9B on both sides of the central opening corresponding to the finger 4. That is, the finger 4 is divided into two parts 41 and 42 on both sides of the through hole 40 as a boundary.
And a fin gas topper opening 9B for the other portion 42. The fingers 4 are stored in a plurality of stages in the finger topper 9 and perform the needle selection operation as described above. FIG. 6B shows an example in which ten stages are provided, and fingers 4 are stored in each stage. Here, the stopper operation of the finger 4 at the finger topper 9 will be described.

The apertures 9A, 9 of the fin gas topper 9 at 1, 42
It comes into contact with the inner wall of B and is stopped. Jack 5
In FIG. 6 (B), when the front end portion that contacts the finger bat 6 is obliquely inclined, the front end is pressed as illustrated by an arrow mark when contacting the pad 6 in FIG. It is stopped by the inner wall of the stopper opening 9A.

However, when the through holes 40 are formed in the fingers 4 as described above, the portions 4 on both sides of the through holes 40 are formed.
In steps 1 and 42, deformation (thermal strain) and torsion occur due to the metal heat treatment in the manufacturing process of the finger 4 and the fingers 4 do not become parallel (different degrees of inclination). As shown in FIG. 7 (A), the finger 4 may hit one side in the metal topper 9. When observing the electronic waveform of the movement of the finger 4 at that time, the waveform is disturbed due to the above, and it affects the sock handle. Further, the above finger 4
Then, as described above, the butt 6 for the finger of the jack 5
As shown in FIG. 7 (B) , a load is applied when the finger 4 comes into contact with the upper surface, and as shown in FIG. 7 (B) , the finger 4 does not rise upward because the side surface 9A is worn and a step is generated on the side surface. May hinder a smooth needle selection operation. Therefore, in order to prevent the wear of the fin gas topper 9, the fin gas topper 9 may be made of a hard material that has been subjected to a quenching process. As shown in FIG. 7C, in combination with the fin gas topper 9 made of a hardened steel material,
The finger 4 is the inner wall 9A, 9B of the opening of the fin gas topper.
This makes it easier to bounce when it comes into contact with the device, which also hinders a smooth needle selection operation. The present inventor examined the use of a fin gas topper 9 as shown in FIG. 6B, which was not hardened as a whole, but was hardened only on one side half where wear prevention was required. In that case, it will prevent wear,
The bouncing phenomenon was not eliminated. In particular, recently, the speed of the needle selection device has been increased, and the speed of the knitting machine has been increased, and the rotation speed of the cylinder has been significantly increased. Therefore, the degree of wear of the fingers and the fin gas topper has also become remarkable. I have.

And a needle selecting device for a knitting machine characterized by comprising the above-mentioned finger and the above-mentioned fin gas topper. In particular, a needle selecting device for a knitting machine is a needle selecting device for a knitting machine that uses a piezoelectric body as a finger operating portion and applies a voltage to a piezoelectric element of the piezoelectric body to select a knitting needle of the knitting machine. It is characterized by .

[0008]

According to the above means, the finger is operated by the finger.
Part (piezoelectric body) attachment part, knitting needle or lower part of the knitting needle
Abutting part that contacts the finger bat of the jack
A finger connected between the center of the mounting part and the contact part
And the finger component is strip-shaped.
And a single contact with the fin gas topper section, so that the fin gas topper is divided into two parts on both sides of the conventional through hole, and corresponds to the finger. Unlike one in which one Fingas topper opening is opened, one Fingas topper opening is sufficient, and one stopper body in which the one Fingas topper opening is opened is , It can be made of a soft material that has not been subjected to a quenching process in consideration of the bouncing phenomenon, while the other stopper body can be made of a hard material that has been subjected to a quenching process in consideration of wear prevention. Therefore, the fin gas topper can prevent the bouncing phenomenon, can also prevent abrasion, improve durability, and have a long life. In addition, as a result of the finger being lighter, the needle selecting operation is remarkably speeded up as compared with the conventional case, and since the finger is configured to make a single contact with the finger topper, the conventional through-hole is formed. And the occurrence of thermal distortion (deformation), twisting, etc., which occur when two parts on both sides are provided with the through hole as a boundary, are reduced. In addition, the electronic waveform becomes normal, and the influence on the sock handle, which is caused by the disturbance of the electronic waveform, can be avoided (pattern mistakes can be eliminated). Further, since the surface area in contact with the fin gas topper is reduced, it is possible to prevent a phenomenon that the conventional finger adheres to the fin gas topper while being in contact with the fin gas topper. Furthermore, even when the speed of the knitting machine is increased and the load on the fingers is greatly increased, it is possible to prevent the wear of the sidewall of the finger topper due to the increase in the pressing force due to the high-speed rotation of the knitting machine. Prevention can be dealt with sufficiently.
Furthermore, since the needle selection speed is improved based on the weight reduction of the fingers, for example, conventionally, for example, 12 steps of fingers and a finger topper were required. It is possible to use only a suitable topper, and the number of drive circuit boards in the control for operating the fingers was reduced, and the needle selecting device was further reduced in size.
