Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a pile pattern forming device for a circular knitting machine for knitting socks, stockings, etc. This invention relates to a pile patterning device suitable for a wide range of pile patterning using a fine gauge for knitting.

(Prior Art) A pile patterning device for this type of circular knitting machine that has already been proposed is constructed as shown in FIGS. 11 to 14 (Japanese Patent Publication No. 5345/1983).

That is, in FIGS. 11 to 14, a well-known knitting machine cylinder b is rotatably fitted in a machine frame a of a circular knitting machine, and a large number of longitudinal A groove c is formed,
As shown in FIGS. 13 and 14, each vertical groove c has a knitting needle d and a sinker select jack e.
are alternately fitted so as to be moved up and down by a cam member f or the like. Further, a sinker bet (also referred to as an outer sinker ring) g is provided on the upper outer circumferential side of the knitting machine cylinder b, and is fixed to the machine frame a.
In this sinker bet g, sinker grooves h are formed radially in the horizontal direction and are shifted by one pitch with respect to each of the vertical grooves c. Furthermore, each sinker groove h
Each sinker i is fitted so as to be slidable in the horizontal direction, and each sinker i has a tapered surface i ₁ at the upper end of the sinker select jack e, as shown in FIG. It is formed so as to come into contact with e ₁ . Furthermore, in each sinker i, the upper claw i ₂ is formed to form a long sinker loop (pile), and each sinker i below the upper claw i ₂ has a short lower claw i ₃ . Shinkaroop (flat knitting)
It is formed to organize. Further, a sinker cap k is provided above the sinker bed g so as to cover each of the sinkers i, and a sinker ring j is provided inside the sinker bed g located on the opposite side of the sinker cap k. The sinker i is provided to guide the sinker i in the axial direction of the eccentric cylinder b.

On the other hand, on the machine frame a outside the knitting machine cylinder b, as shown in FIG.
A plurality of solenoid actuators m selectively push each of the taper actuating pieces _m1 of each of the butts _e2 of each of the sinker select jacks e. It is provided.

Therefore, as shown in FIG. 13, the pile patterning device in the circular knitting machine described above rotates when the knitting machine cylinder a rotates when plain knitting is performed using the base yarn BY and the pile yarn PY. At the same time that the knitting needle d is moved up and down by a cam member consisting of a raising cam and a lowering cam (not shown), each sinker i is guided by the sinker ring j and slides inward, and the lower claw i ₃ of each sinker i is guided by the sinker ring j. It is now knitted into short sinkal loops (flat knitting).

On the other hand, as shown in FIG.
When pile knitting is carried out in PY, as the knitting machine cylinder a rotates, the knitting needles d are moved up and down by a cam member consisting of a raising cam and a lowering cam (not shown), and at the same time each sinker i is moved to the sinker ring j. Each sinker i is guided and slides inward.
At the same time as knitting a short deer loop (flat knitting) with the lower nail i ₃ of By selectively pushing each butt _e2 of each sinker select jack e with each taper operating piece _m1 of m, the upper end _e1 of each sinker select jack e is brought into contact with the tapered surface _i1. come into contact with Then, by pushing the tapered surface i ₁ of the upper end e ₁ of each sinker select jack e,
The entire sinker i is guided by the sinker ring j and slides inward, and the upper claw i ₂ of each sinker i knits a long sinker loop (pile knitting) (see Figure 14). ).

(Problem to be Solved by the Invention) However, as shown in FIG. 13, the pile pattern forming device in the above-mentioned circular knitting machine has knitting needles d and sinker select jacks e in each longitudinal groove c, and a cam member f, etc. Since the needles are fitted alternately so as to move up and down, the needle pitch is doubled, which not only makes the gauge width coarser but also increases operating resistance, making high-speed knitting difficult.
It is difficult to create a pile pattern using a fine gauge that knits fine stitches.

On the other hand, a pile pattern forming device in a circular knitting machine is equipped with a large number of pins using a ratchet mechanism in order to form a pile pattern on socks, for example, as in the invention described in Japanese Patent Publication No. 41-22345. By intermittently rotating the pin drum, each pin of this pin drum is selectively pushed through multiple fingers, jack sliders, and sinker sliders, and at the same time, knitting needles that move up and down are used to knit plain socks. However, this specific example not only has a complicated structure and a large number of components, but also increases the size of the entire device.Moreover, the ratchet mechanism requires a pin drum with a large number of pins. Due to the intermittent rotation, the pile patterning operation is slow and high-speed pile patterning operation cannot be achieved, making it difficult to improve productivity.

The present invention has been made in view of the above-mentioned circumstances, and aims to improve productivity by miniaturizing the entire device, performing pile patterning operation at high speed, and knitting fine stitches. To provide a pile patterning device suitable for a wide range of pile patterning using a fine gauge.

(Means for Solving the Problems and Their Effects) The present invention provides knitting needles in a knitting machine cylinder so as to be moved up and down by a cam member, a sinker bed on the upper outer periphery side of the knitting machine cylinder, and a cam groove in the sinker bed. A plurality of upper and lower pairs of select jacks and pile sinkers are slidably fitted so as to be pushed horizontally by each horizontal feed cam member, and each butt is formed at the outer end of each select jack. , each actuator is provided on each of the butts so as to be pushed by the knitting program signal of the pattern control device, a pile loop land and a nose are formed on the upper part of each of the pile sinkers, and one end of each of the pile sinkers is connected to the select gear. For example, when creating a pile pattern on plain socks, each actuator is selectively pushed by the knitting program signal of the pattern creation control device. Each butt of the select jack is pushed, and the pile sinker that engages with each select jack is pushed in the horizontal direction, and at the same time, the knitting needle moves up and down to create a pile pattern on the plain color of the socks, creating a high-speed pile pattern. This action improves productivity and allows a wide range of pile patterns to be created using a fine gauge that knits fine stitches.
