Description

Open combined winding device for knitting for circular knitting machine}

The present invention relates to an open and open winding device for knitted fabrics for circular knitting machines. More specifically, in knitted fabrics containing spandex, when winding a cylindrically knitted fabric, it is folded and rolled. At this time, the folded part is not pressed, so fold marks are left. To prevent wrinkles from leaving marks that remain after processing, unfold one side of the round fabric that is knitted and roll it on a paper pipe to prevent it from folding. After winding the fabric woven on a circular knitting machine into a tube shape or cutting it into a sheet, It relates to a winding device for open knitting for circular knitting machines that produces final fabric rolls according to the winding form that is opened and wound on a roll.

Knitted fabric is a fabric in which the structure is formed by intertwining ring-shaped stitches without intersecting threads. It has excellent stability against wrinkles compared to other fiber fabrics such as knitted fabrics or non-woven fabrics, and has hygroscopicity, elasticity, and elasticity due to the porous structure. It has excellent wearing comfort characteristics.

Since only one type of knitting yarn, either warp or upward, is used in knitting, the knitting yarns are not divided into warp and weft threads like in cross-structure knitting, but the horizontal portion of the knitting yarn is used to distinguish the knitting direction of the fabric. The section is divided into courses and the vertical portion is divided into wales.

The machine that produces such knitted fabrics is called a knitting machine. The knitting machine forms knitting loops by individually or collectively moving knitting needles with hooks formed at the tip and performs the knitting work of binding adjacent knitting loops to each other. Depending on the direction, it is classified into warp knitting and weft knitting.

Among these, weft knitting machines can be further divided into circular knitting machines and flat knitting machines. The circular knitting machine to which the present invention belongs is a type of circular knitting machine, and knits tubular knitting fabrics. In the case of a conventional circular knitting machine, the tubular knitted fabric produced from the circular knitting machine is folded and wound, or the tubular knitted fabric is cut and then unfolded and wound.

Conventionally, the winding roll on which the fabric is wound is separated into two, one of which is wound and stored in a cylindrical form, and the other is stored in a layered form.

To solve this inconvenience, currently woven fabrics are wound into bundles of flat (fabric) cloth through a fabric winding device located below each circular knitting machine.

However, according to the conventional winding method, although produced on the same circular knitting machine, differences in characteristics such as tension and density occur between the wound knitted fabric and the laminated knitted fabric, making it difficult to provide knitted fabric of uniform quality.

A side plate 240 and a horizontal frame 260 connected to the upper part of the side plate 240 mounted on both sides are coupled (cross-shaped arrangement) orthogonally to the horizontal frame 260 and form a plane surface as the cylindrical fabric passes through. A main body 200 having a slit frame 280 with slits 282 formed thereto; A supporter 320 coupled to the upper part of the horizontal frame 260 and connected slanted upward, and a fabric weaving portion 300 attached to the upper end of the supporter 320; A deployment frame 400 attached to the lower part of the horizontal frame 260 and spreading the fabric L passing through the slit 282 of the slit frame 280; It is comprised of an idle roller (IR) that continuously moves the unfolded fabric through the deployment frame 400, and a fabric roll (PR) that winds and stores the fabric (L).

The slit frame 280 is formed in a square shape and is made up of a plurality of pipes arranged in parallel therein. Slits 282 are formed between the pipes to guide the fabric so that it can be transferred in a plate shape.

The cylindrical fabric (L0) can be cut in the longitudinal direction, unfolded into a plate, and discharged as a single-ply fabric, which can then be wound on a fabric roll (PR).

A cutter unit 500 is mounted on one end of the slit frame 280 to cut the cylindrical fabric L0. The cutter unit 500 cuts the cylindrical fabric (L0) in the longitudinal direction to create the unfolded fabric (L).

The cutter unit 500 includes a body 510 having a cutting groove 520 into which the fabric L0 is inserted, a cutting blade 530 standing perpendicular to the cutting groove 520, and the cutting blade 530. Includes a motor 540 that rotates.

Therefore, just before the cylindrical fabric L0 enters the slit 282, it is continuously cut by the cutting blade 530, and it can be spread into a plate shape on the deployment frame 400 and wound on the fabric roll PR.

The deployment frame 400 is formed into a '〉' shape by bending on both sides based on the middle of the circular rod, is attached to the lower part of the horizontal frame 260, and is cut while passing through the slit 282 of the slit frame 280.
