Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock raising method and apparatus.

[0002]

2. Description of the Related Art In order to keep warmth in circular knitted knitted goods such as socks, it is often desired to nap them. In response to this demand, attempts have been made to raise a knitted fabric simultaneously with knitting on a circular knitting machine, as in Japanese Patent Publication No. 59-14585 and Japanese Utility Model Publication No. 58-42476.

However, in all of these conventional techniques, a raised brush using a needle for implanting stainless steel wire or the like is pressed against the surface of the knitted fabric. As a result, there are many accidents where needles break and bite into knitted products.

In the case of socks, since the knitted fabric is loosened during knitting, the bag portion consisting of the heel portion or the like catches the needle, and the brush cannot raise the heel portion. For example, the conventional socks for cold weather disclosed in Japanese Utility Model Publication No. 58-48321 are:
It consisted of bar-shaped socks with no heel bag.

BEST MODE FOR CARRYING OUT THE INVENTION Next, the sock raising method and apparatus of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view of essential parts showing an embodiment of a single knitting machine. FIG.
FIG. 2A is a rear view showing an embodiment of the nip disc including the fabric cap according to the present invention.
2B is a cross-sectional view taken along the line AA of FIG. 2A. FIG. 3 is a plan view in which a sock manufactured by the method of the present invention is turned upside down.

The single knitting machine S shown in FIG. 1 is a B type / K type sock knitting machine. Reference numeral 1 is a rotating cylinder body, 2 is a needle of a knitting needle, and 3 is a sinker for moving back and forth to press a knitted fabric or to form a pile. 4 is a sinker
Ring 5 is a sinker bed and 6 is a sinker cap. The sinker cap 6 is pivotally attached to the shaft 7 so that the sinker cap 6 can be raised when not knitting.

Numeral 8 is a nip disk comprising the fabric cap of the present invention. The nip disc consisting of the fabric cap referred to in the present invention,
The knitted fabric is a disk-shaped plate which is pressed from above so that it does not float up, and the slits 9 and 10 serve as knitting yarn guides.

A guide pin 11 is vertically provided on the upper surface of the center of the fabric cap 8.
The pin 11 is axially supported by a ring 13 via a vertical key groove 12 so as to be vertically movable. The ring 13 is supported by the lever 14, and the other end of the lever 14 is screwed into the hole 16 of the sinker cap 6 by the bolt 15 so that the fabric cap 8 is integrated with the sinker cap 6. Can operate. One end of the rod 17 is fixed to the upper end of the guide pin 11, and the lever is attached to the other end of the rod 17.
A tension spring 18 is biased between the spring 14 and the spring 14. However, this structure is merely an example even if it gets tired.

FIG. 2 shows a nip disk 8 comprising the fabric cap of the present invention. The slits 9 and 10 have tips 10a so that the knitting yarns can be easily guided.
Has a tongue piece 9a that is acutely angled or bent upward.

The upper surface of the sinker ring 4 is formed with an inverted conical taper 4a so that the knitted fabric can be smoothly pulled into the cylinder body 1 and its diameter is reduced. Therefore, in the case of this embodiment, the outer periphery 19 of the lower surface of the fabric cap 8 is an inclined surface along the taper 4a. A rough surface 20 such as a file surface is formed on the surface of the outer circumference 19. The rough surface 20 of the present invention is too strong for a brushed brush made of a needle-implanted needle such as a stainless steel wire or a protrusion such as Oroshi gold, and is too weak for a hair-polished brush that is worn away. It is preferably a rough surface having no catch such as a filed surface. The position and the like of the rough surface 20 in this embodiment are merely examples, and for example, the flat back surface 21 may be provided with a slightly wider area, or the rough surface may be formed in a spiral pattern that is sub-shaped in the advancing direction of the knitted fabric. Good. The rough surface 20 can be roughened by sanding, pressing with an inverted rough surface, engraving with a punch, satin treatment with a chemical treatment, or the like.

The rough surface 20 formed on the surface of the nip disk 8 made of this fabric cap is brought into contact with the inner surface 23 of the knitted fabric of the sock 22 shown in FIG. The sock 22 of this embodiment is high socks up to the knee length, the leg 25 is made of flat knitting, the instep part 26 is made of ridged pile knitting, and the other part 27 is heel / sole. -The toe part is made of pile knit. Therefore, in the raised hair 24 of the present invention, the leg portion 25 of the flat knit portion is slightly raised. On the other hand, in the pile knitting portion below the ankle portion 28 where heat retention is desired, since the rough surface 20 makes stronger contact with the top of the rising pile, sufficient raising is performed.

FIG. 4 is an explanatory view of a principal part mainly showing a longitudinal section of a rib knitting machine comprising a double knitting machine D, showing another embodiment of the method and apparatus of the present invention. The rib nitter D has upper and lower two cylinders, an upper cylinder 101a and a lower cylinder 101b. Therefore, by using a double-headed needle and freely transferring this needle to the upper and lower cylinders 101a and 101b, the surface of the lower cylinder 101b can be changed to the upper cylinder 101b.
The back stitch is knitted with a to enable various knitting such as rib knitting.

The rotation of the cylinders 101b and 101a is transmitted by the bevel gears 129a and 129b and the vertical axis 130, the speed can be changed by the speed change mechanism 131, and the reciprocating rotation can be performed by the clutch 132. That is, the rotation of the cylinder 101 is performed by fitting it into the tubular portion of the sleeve gear-133.

The knitted fabric 122 has a cylinder 101.
It is wound up through a fabric tube 135 via a fabric guide 134 therein. However, when the knitted fabric 122 is a sock, since there are bag portions such as a heel portion and a toe portion, it is necessary to take measures to eliminate looseness of the knitted fabric at this portion and obtain a uniform winding tension. .

The presser weight 136 for knitting the bag portion according to the present invention is therefor. Presser
The shaft 137 of the weight 136 rotates together with the cylinder 101, although the transmission mechanism is omitted in FIG. The claw piece 138 at the lower end of the presser weight 136 is a pin 1
It is rotatably pivotally attached to 39 and can move up and down. Therefore, when the bag portion is knitted, the loose knitted fabric of the bag portion is wound around the claw piece 138 and pulled, so that a uniform winding tension can be obtained.

In the case of the double knitting machine D, the nip disc 108 of the present invention utilizes this presser weight 136. The shaft 140 of the nip disk 108 penetrates the shaft 137 of the presser weight 136 so as to cover it. Although the transmission mechanism is omitted in FIG. 4, the key groove 141 prevents rotation.

A cylindrical presser disc piece 142 is fixed to the lower end of the shaft 140 of the nip disc 108. The presser disc piece 142 has a roughened surface 120 on the outer peripheral surface. The rough surface 120 contacts the inner surface 143 of the knitted fabric 122 that is wound while rotating, and the raised surface 124 is applied to the surface portion of the knitted fabric inner surface 123 between the rough surface 120 and the fabric tube 135.

[0020]

According to the method and apparatus of the present invention, it has become possible to nap a sock having a heel portion, which has been impossible in the past.

Since the method and apparatus of the present invention do not use a raised brush composed of a needle for implanting stainless steel wire or the like, it is possible to prevent an accident where the needle is broken and enters the product.

By using the method and apparatus of the present invention, the pile knitted portion and the flat knitted portion can be raised under the same conditions, and the flat knitted portion is lightly raised and the pile knitted portion is finished with stronger raising. You can
