Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a circular knitted cylindrical raised product and an apparatus for producing the same, and more specifically, the present invention relates to a circular knitted cylindrical raised product and an apparatus for manufacturing the same, and more specifically, the cylindrical raised product is raised only around one-half of the circumference in the rotational direction of the cylinder, and other The present invention relates to a circular knitted cylindrical raised product whose parts are plain knitted or patterned knitted, and an apparatus for producing the same.

<Prior art> The circular knitted cylindrical hair product and the manufacturing apparatus thereof according to the present invention are those in which a raising brush is provided on the circular knitting machine table to raise the circular knitted fabric in the cylindrical rotation direction at the same time as knitting. However, currently, the cylindrical brushed product has a sinker loop formed on the inner surface of the entire circumference in the direction of rotation of the cylinder.
This top part was to be raised.

Therefore, it has been impossible to apply loop raising only to about one half of the circumference in the direction of rotation of the cylinder and to form plain knitting or patterned knitting in the other parts. The reason is that if you apply the sinker to only about one-half of the circumference in the direction of rotation of the cylinder, and do not apply the sinker to the other parts,
Although it is possible to obtain such a circular knitted cylindrical raised product, it has the disadvantage that it cannot be commercialized because the flat knitted or patterned knitted part where no sinker is applied pulls and becomes unbalanced. .

<Problems to be Solved by the Invention> In view of the above-mentioned circumstances, the present invention has been developed by applying loop raising only to about one half of the circumference in the direction of rotation of the cylinder, and using flat knitting or patterned knitting which does not cause tension in the remaining part. The purpose of the present invention is to provide a circular knitted cylindrical raised product consisting of parts and its manufacturing equipment.

<Means for solving the problem> Therefore, the present invention uses a knitting yarn consisting of a front yarn, a core yarn, and a back yarn, and forms a sinker loop with the back yarn around one-half of the inner surface. The top of the loop is raised in the cylindrical rotation direction, the remaining half circumference is plain knitted or patterned, and the stitches in the plain or patterned part are wider than the raised part, and in addition, the cylindrical part of the raised part is The above problems are solved by providing a large-diameter circular knitted cylindrical raised product characterized in that the terminal sinker loop in the rotating direction is smaller than other sinker loops in the raised part.

The present invention also provides an apparatus capable of manufacturing a large-diameter circular knitted cylindrical raised product that solves the above-mentioned problems. The apparatus for producing a large-diameter circular knitted cylindrical raised product of the present invention is characterized in that the circular knitting machine is capable of producing approximately 200 knitted circular knitted fabrics knitted by flat knitting or pattern knitting.
A means for widening the stitch of one turn is provided, and the means for widening the stitch is composed of a lowering cam of the knitting needle and a lever mechanism for moving the cam in the vertical direction. This lever mechanism includes a ring cam 19 that protrudes radially outward from about one half of the circumference of the cylindrical outer edge 17 of the hook, members 20 and 21 that move radially outwardly by engaging with this ring cam 19,
22, and members 23 and 24 that are connected to the member that moves in the radially outward direction and convert this radially outward movement into downward movement. The knitting needle lowering cam 16 is connected to members 23 and 24 that convert the movement downward, and by moving the knitting needle lowering cam 16 downward, the retraction amount 26 of the knitting needle is increased. It is characterized by what it did.

In the present invention, a large-diameter circular knitted cylindrical raised product refers to a circular knitted cylindrical raised product with a cylinder diameter of approximately 7 inches or more, which is used for purposes such as pants and sweaters other than socks.

<Function> In the large-diameter circular knitted cylindrical raised product of the present invention, knitting yarn consisting of a front yarn, a core yarn, and a back yarn is used to
Form a sinker loop with the back thread for 1/2 of a turn, raise the top of the loop in the direction of rotation of the cylinder, and leave about 2
By making the stitches in the plain knitting or patterned knitting part wider than the raised part in flat knitting or patterned knitting for one round, the imbalance between the raised part and the plain knitting or patterned part is corrected, and the flat knitting or patterned knitting Or eliminate the occurrence of tension in the pattern knitting part. Furthermore, by making the terminal sinker loop of the raised part in the cylindrical rotation direction smaller than the other sinker loops of the raised part, it is possible to prevent the raised part from covering the pattern at the starting end of the flat knitting or patterned knitting part and causing irregularities.

In addition, in the apparatus for manufacturing a large diameter circular knitted cylindrical raised product of the present invention, a ring cam 19 that protrudes radially outward at approximately one half of the circumference of the cylindrical outer edge 17 of the hook is provided with a member that moves in the radially outward direction. 20, 21, and 22 are engaged, and these move in a radial outward direction during approximately one half of the circumference of the hook. This movement is transmitted to the knitting needle lowering cam 16 by members 23 and 24 that convert this radially outward movement into downward movement, and the knitting needle lowering cam 16 moves downward. As a result, the retraction amount 26 of the knitting needles becomes large during about 1/2 of a turn, and the stitches of about 1/2 of a turn of the circular knitted fabric knitted by plain knitting or patterned knitting become wider.

<Example> The attached FIGS. 1 and 2 show a circular knitted cylindrical raised product showing an example of the present invention.

In No. 1, the outer yarn is made of sweat-absorbing acrylic yarn, and cotton yarn may also be used. 2 is a core yarn made of spandex yarn, which may also be a nanlon yarn. 3 is a backing yarn made of interwoven yarn that can generate negative static electricity, and may be made of wool or cotton.

Figure 2 shows pants made of cylindrical circular knitted fabric, which may be sweaters or the like, but excludes socks.
indicates the back of the inside out. Approximately one-half of the circumference of the back side in FIG. 2 is made up of a flat knitted or patterned knitted portion 9, but the stitches 10 are wider than those of the raised portion.

Further, the terminal sinker loops 11, 11, 11 of the raised portion 7 in the cylindrical rotation direction 5 are made smaller by 3 to 5 loops. This is because the raising 6 is performed in the cylindrical rotation direction 5, so it is difficult to see in Figure 2, but it is necessary to correct the unevenness caused by the raising 6 covering the pattern of the starting end 12 of the plain or patterned part. That's why.

The following FIGS. 3, 4, and 5 show a circular knitted cylindrical raised product and a manufacturing apparatus thereof, showing one embodiment of the present invention. The circular knitting machine has a sinker 12 for forming a sinker loop 4, and is provided with a nap brush 13 for raising the nap in the cylindrical rotation direction 5, and 14 is a saucer for the nap, and the flat knitting or pattern knitting part 9 A lever mechanism 18 provided on the outer edge 17 of the cylinder is operable to lower a cam 16 for lowering the knitting needle 15 to widen the stitches around the remaining half circumference. This is fundamentally different from conventional control drum-based actuation.

Here, the lever mechanism 18 means that a roller 20 that rotates on the surface of a cylindrical outer edge 17 and a stepped ring cam 19 attached to the approximate radius thereof is connected to a sliding rod 22 together with a seat plate 21.
move back and forth. The forward and backward movement of the sliding rod 22 operates a lowering cam 16 at the tip of the lever 25 via a bar 24 from an L-shaped support rod 23 fixed thereto, thereby adjusting the retraction amount 26 of the knitting needles 15...15. In addition,
15a is the butt part of the knitting needle, 27 is a cylindrical cylinder, 28 is a bevel gear, 29 is a raising cam, 3
0 is a cam ring, and 31 is a cam holder.

<Effects of the invention> It is possible to produce circular knit cylindrical raised products such as pants, sweaters, etc., where the front side is plain knitted or patterned knitted and the back side is internally raised, and the front side is smart and the back side has good heat retention. We have created a device that can produce items that do not have taut patterned parts. This is different from the conventional method in which a lowering cam is operated from a control drum, and provides a useful and novel circular knitted cylindrical raised product that can be knitted even with knitting yarn that does not stretch and can be easily adjusted, and its manufacturing device. It is something to do.
