Abstract

The needle cylinder assembly is composed of parallel needle grooves along the shaft line. Needles are set in the groove to move in the needle grooves to the shaft direction by a cylinder. A reciprocating device moves a descending can assembly cross the needles on the needle cylinder. Multiple extruders, which have a ring around the cylinder, are fixed on the cylinder to move along the cylinder. The extruder makes a stitch on the needle by ascending a group of needles when the extruder moves on the cylinder and descending the needle, which is jointed with the descending cam assembly. The yarn is delivered to the needle when the cam assembly draws the needle downward.

The present invention relates to a method and apparatus for knitting a jersey fabrie with a design of multi-color intarsia, and in particular a special circular knitting which can be either a knitting machine or a single jersey knitted fabric. A method and apparatus for knitting a jersey knitted fabric of an Intasha design by controlling needle movement on a machine.

Both circular knitting machines and flat knitting machines are used to knit jersey knits and rib fabrie. Circular knitting machines have more feeds than flat knitting machines and can be operated at substantially higher speeds. The price of the knitted fabric by the circular knitting machine is lower than the price of the knitted fabric by the transverse knitting machine.

In a circular knitting machine the needles are arranged at regular intervals in the grooves of the cylinder dulene. In knitting, each needle is raised to a cleared position and pulled downward to form a slit. As the needle is raised, the needle latch is opened by a stitch loop that was in the needle hook before raising the needle. As the needle is pulled downward, the needle hook engages with the new yarn fed to the needle by a yarn feeder. The needle latch is closed by the ball ring on the needle as the cold loop slips over the latch. The new yarn coupled to the needle hook is pulled by a globular ring on the needle to form a new stitch. The needle, which is raised and supported downward, is released from the needle when the needle is pulled downward. The needles are gradually raised as the knitting machine rotates and pulled downward one by one by the cams. Depending on the cam length, the needles in front of the cam in the direction of knitting machine rotation are in the forward position to be raised, while at the same time the multiple needles on the cam are in the forward pulled position. Knitting can be knitted to a substantial length during every turn of the knitting machine by providing a knitting machine having a plurality of cams arranged at regular intervals and the same number of yarn guiders.

The cylinders and dials on the jersey circular knitting machine and the cylinders and dials on the jersey and rib circular knitting machine are rotated and at the same time the cam and yarn guiders are supported at rest, or in some cases the cylinders or cylinders and dials are held at the same time and Yarn guider can be rotated. The fabric to be knitted is rotated or supported with the cylinder depending on whether the cylinder is rotated or stationary.

So far, attempts to knit single flat knit jerseys without floats on circular knitting machines have been unsuccessful with the same color design as the Intasha color design. The knit bottom knit with floats makes the fabric somewhat heavy. On the other hand, a single flat knit jersey knit without intasha design knit or float can be knitted to have a design on both sides of a flat knit jersey knitting machine when it is knitted on a circular knit jersey knitting machine, and when the design does not appear on the front side of the knitting fabric. The callayan, like a float, remains on the back side of the knitted fabric and must be threaded on the back side of the knitted fabric or tripped in some form from the back side of the knitted fabric. The collar yarn on the back of the knitted fabric, such as float, or operated on the back of the knitted fabric, degrades and unaccepts the thread of the appearance of the circular knit. Trimming the calla yarn from the back side of the knitted fabric should be done with great care not to damage or weaken the knitted fabric. Moreover, trimming increases the price of the knitted fabric.

Apart from the appearance and acceptance of the ulticolor collar knit of this knit design, trimming the color yarn from the backside of the knit design increases the price of the knit fabric and is the most common in knitting such knit design knit into a circle on a circular knitting machine. The method and apparatus used as is complex and quite expensive. Needles for knitting designs in conventional methods and apparatus used to knit multi-color knit design knits with the exception of color strips are selected by so-called jacquard technology. The selected needle changes as the knitting operation progresses and the design changes. This jacquard technology controls needle jacks using needle ejected and punched cards, pattern drums, pattern drums and disks, punched metal tapes and pattern drums or photosensitive electronic tapes. Control with these jacks increases the size of the device, increases the cost, and increases the cost of implementing discrete jacquard technology.

In the present invention, it is possible to overcome the above-mentioned problems in knitting a knitted fabric having a geometric design of the color design Intasha and Dulticolor knit on a flat circular knitting machine, so that both the front and the back of the knitted fabric have a color design. Make a knitted fabric. This can be achieved in the present invention by moving the needle and yarn guide in a new way, ie by first moving in one direction and then in the opposite direction with respect to the cylinder and needle to knit the knitted fabric.

In the present invention, the needles are divided into groups of adjacent consecutive needles. The group of needles is advanced or raised alternately on the cylinder. The needles advanced or raised in the group are pulled downward by the knocking cams individually in succession one by one. The needle of the advanced or raised group is pulled by the lowering cam and at the same time successive needles of the next group to be knitted by this cam are raised.

One descending cam is installed for a pair of continuous needle groups. The lower cam is arranged at regular intervals around the cylinder and reciprocates back and forth around the cylinder. The yarn guide is installed at each lower cam position and repositioned with respect to the needle and the lower cam, where the needle and the lower cam are fed to the reciprocating end of the lower cam in each direction so that the needle is raised and lowered by the lower cam which moves in the opposite direction. As it is pulled in, it engages with the needle hook. The cam face of the lower cam is coincident in the opposite direction of the lower cam reciprocating motion. Therefore, the raised needles in either of the reciprocating directions of the lowering cam are successively pulled downward alternately by the inner cam moving next to the needle.

Each group of adjacent consecutive needles is equipped with a pusher that simultaneously raises the grouped needles on a cylinder. When raised, the grouped needles are individually supported in the raised position on the cylinder until pulled downward by the internal cams. As will be clear from the yarns of the invention described hereafter, the extruder for the even-numbered group of adjacent successive needles has one actuator, for example a cam and the extruder for the odd-numbered group of needles has a second Actuator, for example, a second cam. The actuator and the extruder are retracted when the actuator advances or raises the extruder to simultaneously raise the needles alternately up to their raised position. As is known, the needle is supported in the advanced or raised position until it is pulled in the direction by the lowering cam.

The reciprocating motion in each direction of the descending cam past the raised needle of the needle group associated with the descending cam produces a pair.

When the knitting stage in one direction is completed, the direction of movement of the lowering cam is reversed, the yarn guider is repositioned, and the naram cam is moved in the opposite direction past the advanced or raised needle of the needle group to produce the next knitting group. The reciprocating motion in this direction, the reciprocating motion in the opposite direction and the reciprocating motion in the opposite direction of the lowering cam are repeated while the knitted fabric is knitted. The yarn guider is repositioned so that the reciprocating motion of the down cam is reversed, and the course is organized when the down cam is reciprocated in the opposite direction after the associated forward or rising needle pulls the last needle of the group too downward, The lower cam continues until its reciprocating motion passes the last needle without knitting, and the Jangider is repositioned and the last group of needles that are knitted are advanced or raised so that the position latch is moved in the opposite direction of the lower cam. Open the needle latch for the retracted extruder to remove the reach and lower cams. The lower cam is then reciprocated in the opposite direction past the raised needle as described in detail below.

The color design knitted fabric according to the method and apparatus of the present invention has two or more colors. Color yarns, including white, are fed to the needles in a group of needles where the collar appears in the design by a yarn guider installed on the yarn carrier. The needles are pulled backwards or downwards through the raised needle, which is advanced or raised at the same time and then individually successively in alternating succession, initially reciprocating in one direction and then in the opposite direction, pulling the needle downwards, and the yarn being knitted and knitted do. By racking cylinders and needles against yarn carriers, extruders and extruder actuators and descending cams, the Intasha design, which is knitted in Dalayan on a knitted fabric after one or more stages are knitted, can be processed diagonally on the knitted fabric. have. Racking cylinders and needles and yarn guiders with respect to extruders and down cams allows the Inthasha design knitted with color yarns to be knitted into diamond patterns, circles or other design shapes as will be described in detail below.

The present invention will be described in detail with reference to the accompanying drawings as follows.

The method of the invention is carried out on a circular knitting machine of suitable size which is most suitable for carrying out the method according to the invention. As can be seen from the following description of the present invention, the specific structure of the apparatus for performing the method of the present invention can be modified according to the Intasha design to be knitted. For purposes of illustration and description, the present invention is, in the following description, adapted to a circular knitting machine having a needle cylinder of 33 inches diameter divided into 48 groups of needles of equal size. Each two adjacent needle clusters consist of 36 needles and knitting units. The present invention can be readily applied to cylinders of different sizes, different needle collective compartments and other section arrangements, as will all become apparent from the following description.

Referring to FIGS. 1A, 1B, 1C, and 1D, the essential differences between the prior art methods and the methods of the present invention will be shown and described, and for the sake of clarity the down cam is removed and FIG. In Figs. 1C and 1D, the cylinder groove at the end of the needle is omitted below the needle bit.

In the conventional method of knitting a jersey knit with a circular knitting machine, the lower cam and the yarn guider are supported in a stationary state and the needle cylinder is rotated or the needle cylinder is supported in a stationary state and the knit cam and the yarn guider are continuously rotated. In all these cases, as the down cam passes through each needle, the needle is raised first and the needle latch is opened, the needle hook is engaged with the yarn supplied to the needle by the yarn guider, the needle is pulled in the direction and the needle latch is closed. The old stitch loop is peeled off and the new stitch loop is supported by the needle on the needle. As will be apparent to those skilled in the art from the following description, the present invention can be readily applied to both needle cylinders in which the knitting machine stops or rotates. However, the invention described herein by way of clarity relates to a circular knitting machine in which a needle cylinder is at rest and causes lowering cams, yarn guiders and other components required for knitting operation to rotate or move laterally across the needle. .

In the conventional method carried out by a prior art circular knitting machine having a needle cylinder supported in a stationary state as shown in FIG. 1A, the needle 112 of the needle cylinder 100 in the needle groove 102 is first cammed. And as the yarn guider 113 is rotated to the needle cylinder (100) blunt, it is raised or heard alternately successively one by one by a conventional lowering cam (not shown). The needle latch opens as the needle is raised. The open needle hook engages with the yarn fed to the needle by the yarn guider 113. The needle with the binding yarn is pulled downward through the old stitch loop on the needle by the lowering cam to form a new stitch. As the needle is pulled downward, the needle latch is closed and the needle peels off the old stitch loop in the jersey knitted fabric. The new stitch loop is held by the needle. The lower cam assembly and the yarn guider continue to rotate around the stationary needle cylinder 100. If the cam assembly and the yarn guider are rotated depending on the down cams and yarn guiders arranged at regular intervals around the cylinder, a single stitch is formed on each of the down cams and the yarn guiders. The knitted end is helically passed around the cylindrical knitted tube.

In the method of knitting a jersey knit with a circular knitting machine of a stationary knitting cylinder according to the present invention, the needle in the needle groove of the stop needle cylinder has needles having the same number of needles by an extruder of the same length extending circumferentially around the cylinder. It is divided into groups. The lower cam assembly and the yarn guider reciprocate back and forth around the stationary needle cylinder.

Each group of needles described in detail below is lifted by an extruder. Each needle in the ascending group is alternately pulled downward in succession by the descending cam. Pulled downward. Pulling downwards, each needle forms a new stitch loop from the yarn fed to the needle by the yarn guider and strips the old stitch loop into the knitted jersey. If the raised needles of the first group of needles are alternately pulled downward by the downcam, the group following the needles is raised by the next extruder.

After pulling down and knitting the needles of the first group, the descending cam successively pulls up the rising needles of the second group, forming a new stitch loop with each needle already pulled, and forming a needle from the needle in the knitted jersey. Peel off the stitch loop. After pulling the needle of the second needle group downward, the down cam assembly and the Jan guider are rotated past the second needle group so that the down cam removes the needle butt of the second group needle, and then the second group needle is raised by the extruder. The extruder is retracted, the yarn guider is repositioned, and the direction of rotation of the lower cam assembly and the yarn guider relative to the stationary needle cylinder is reversed.

Referring to FIGS. 1B-1D showing the continuous operation of the needle according to the present invention, the lower cam assembly and yarn guider described in detail below in FIG. 1B pass through the needle 112 on the needle cylinder 100. Completing their movement to the left in Fig. 1b, the down cam (not shown) was raised by the butt 124 of the needle 112 of the first group of needles, the extruder 1 was retracted, and the down cam and yarn guider ( 214 starts moving to the right as shown in FIG. 1B.

As shown in FIG. 1C, the needles 112 of the first needle group are successively pulled downward and pulled sequentially in order as the lowering cam assembly and the yarn guider 214 move from left to right. The hook engages the yarn fed to the needle by the yarn guider 214 to form a new stitch loop on the needle with the yarn. As the lowering cam pulls the needle 112 of the first needle group downward, the extruder 2 begins to move upwards, engages with the needle butt 124 and raises the needle of the second needle group.

As shown in FIG. 1D, when the down cam assembly and the yarn guider 214 continue to move further from left to right, all the needles 112 of the first needle group are pulled down and all the needles of the second needle group ( 112 are pushed upwards by the extruder 2, and then the extruder 2 is retracted to remove the lowering cam, and the lowering cam and the yarn guider 214 are further moved to the right so that the needles of the second needle group ( 112 are successively pulled downwards alternately to form a new stitch loop on each needle currently being pulled.

As described in more detail below, the angled knit cam assembly and yarn guider 214 move past the needle 112 of the second needle group and the down cam removes the butt 124 of the needle of the second needle group, The yarn guider 214 is repositioned, the needles of the second needle group are raised again by the extruder 2 and the butt 124, and when the extruder 2 is retracted, the lower cam assembly and the yarn guider 214 are removed. As shown in FIGS. 1b to 1d, the movement is reversed from right to left.

As can be seen in FIG. 17, the cam hole 150 of the extruder 1 is pulled down in the cam track 152 and the needle 112 in the raised position until it is pulled down by the lowering cam 130a. To rise). As the lower cam ring 132 and the extruder cam ring 158 reach the position shown in FIG. 17, the latch release pin 202 is moved to the cam surface 178 of the latch release 174 (FIGS. 7a, 7b). 8A), the pin 202 and the extruder cam latch 184 are cammed down, and the latch 184 and the extruder cam stop 182 are disengaged. The extruder cam stop 204 (FIG. 7A) is in contact with the lower end of the lever 162.

The extruder cam ring stopper 184 and the down cam ring stopper 182 are separated, and the lowering cam ring 132 moves to the left side, and the extruder cam ring 158 is kept in a stopped state. As the lowering cam ring 132 continues to move to the left (FIG. 18), the lowering cam 130a pulls the raised needle 112 down in the knitted position until all the needles are pulled down by the extruder 1. The tip end (Fig. 7b) of the lowering ring stopper 182 is in contact with the upper end of the lever 162, and the extruder cam rings 158, the extruders 1, 2, the cams 130a, 130b. The cam guides 154, 154a, 154b, 156a, 156b and the needles 112 are in the positions shown in FIG. 7 and described by reference. This cycle of operations is repeated and the rows of stitches are knitted from left to right in each cycle and from right to left in each cycle.

In the above example, since 48 needle groups are installed around a cylinder having 24 lower cams corresponding to one of the two needle groups, the rows are individually organized in each cycle from left to right and each cycle from right to left. The stage has 24 sections.

In the embodiment of the invention shown and described, the extruders 1-48 (FIG. 5) overlap at their adjacent sides. The overlap length and the width of one needle groove are substantially the same. Thus, one needle in the needle groove at the adjacent adjacent edge is raised by the extruder as each extruder is raised. This general ascending operation of one needle that terminates the knitting operation of one needle group and begins the knitting operation of the next needle group, thus knitting a knitting stitch at the end of the knitted fabric organized by one needle group by the needle of the next needle group. To be interconnected with the knitted stitches. Thus the knitted fabric is combined. Rather than overlapping adjacent sides of the extruder, the extruders 1-48 are adjacent and the needle cylinder may be racked after each row of stitches have been knit.

For the purpose of racking the needle cylinder, in the examples of FIGS. 3 and 3A the ring gear 240 is fixed to the inner wall at the bottom of the cylinder 100 and extends around the inner wall. The pinion gear 250 meshed with the ring gear 240 is installed on the bears 101 and the support shaft 244 for rotation. The step motor 246 may be reversely rotated. Since the step motor 246 is operated in one direction, the needle cylinder 100 and the upper body fixed needle 112 are racked in one direction with respect to the extruder 1-48. Racking is reversed by operating the step motor 246 in the opposite direction.

In the example of FIGS. 3B and 3C, the needle cylinder 100 is installed for racking on a fixed cylinder base 101 'fixed to the support 260 (FIG. 3B). The racking control cylinder 262 is secured to the ring gear 264 with the teeth 266 with the upper end fixed to the needle cylinder 100 and the lower end spaced at equal intervals around its periphery. A war gear 268 that engages the teeth 266 of the ring gear 264 with the spiral gear 270 of the forward teeth extending along its periphery in the axial direction is provided at the periphery of the ring gear 264. The teeth 266 of the ring gear 264 and the square spiral gear 270 of the worm gear 268 are fixed to each other so that the rotation of the worm gear 268 and the ring gear in both rotation directions of the worm gear 268. There was a backlash and idle between movements of (264). Thus, one-quarter or ninety degree rotation of the worm gear 268 in all directions advances the control arm 262 and the needle cylinder 100 by one needle groove width or the needle cylinder 100 to the compressor (1-48). The needle length is reversed in accordance with the rotation direction of the worm gear 268 with respect to). The worm gear 268 may be rotated by a step motor control chain or other means. Also other means of racking the needle cylinder 100 and the needle 112 against the compressor 1-48 may be used.

When the extruder 1-48 having the same level as the adjacent edge is used and the knitting needle groups rack the needle cylinder against the extruder 1-48, the needle cylinder 100 racks in different directions at the ends of each knitting end when combined. This racking can be arranged or spaced at regular intervals so that it can be organized without racking in a selected number of stages. If the racking is spaced between the two ends, the eyelet is formed between the knitted, the length of the eyelet is knitted without racking according to the number of stages. In the operation and implementation of the method of the device of the present invention, the yarns, which are knitted according to the design to be knitted, are either one yarn guider installed on a single yarn carrier or one after another supplying yarns to the needles and on separate yarn carriers. It can be supplied to the needle in succession by two yarn guiders installed. In all of these cases, as the lowering cam rim 132 changes the moving direction at the end of the moving direction (Fig. 8 and Fig. 14), the angle at which the yarn is supplied to the needle is reversed so that the needle with the open hook is shown in Fig. 3a. Pulling down from the position to the position shown in FIG. 3 causes the yarn to be knitted to be joined by the open needle hook 114 and pulled down by the needle.

By choosing the color of the yarn to feed the needle, a single knit jersey with a wide variety of intasha designs can be knitted in a wide variety of colors. Thus, a selected group of needles around the needle cylinder may be supplied with yarns of a different color than white or white, and at the same time, other groups may be supplied with navy blue yarns, another group with yellow yarns, and another group with red yarns. One can supply colored yarns, and another group can supply green yarns. By placing a group of yarns of white or non-white color between each color, a low-knit fabric with stripes of a different color than the background that appears white or non-white color can be knitted. By racking the needle cylinder 100 on the needle cylinder base 102, the yarns are fed in one direction after each row is knitted and the other colored rows or vertical stripes knitted into the jersey fabric while the lower cam 132 is operated in reverse. Can be organized diagonally in knitted fabric. The width of the rows or vertical stripes knitted into the knit fabric depends on the yarn guider. Therefore, since a single yarn guider is installed in a needle end consisting of two needle groups, the width of the row or stripe knitted into the jersey by this needle end becomes the same as the needle end width. When two yarn guiders are installed correspondingly in each needle group, the width of the vertical row or stripe can be organized to match the width of the needle group. For example, the number of needles in the needle stage is selected so that two needle groups are alternately knitted from each of the two yarn guiders, so that the width of the column or stripe may vary. A yarn from two yarn guiders may be combined into the fabric as it starts knitting of the yarn from the second yarn guider on the last needle with the yarn from the first yarn guider. Since two yarns are fed to a single needle, a double yarn stitch loop is formed to join the knitted fabric. In the case of two yarn guiders in the needle stage, geometric designs other than stripes can also be organized.

Two yanketiers are provided at the needle ends with their yarn guides and supply differently colored yarns, racking the needle cylinder 100 on the cylinder base 102 and also knitting one or more ends at the needle ends. After racking the yarn carrier, a diamond intasha design can be organized. As racking occurs, the yarns of yarn guiders of one yarn carrier, for example, increase the number of needles that are knitted into white yarns, and the number of needles of yarn guide of yarn carriers of another carrier, for example, indigo yarn, decreases. do. As the cylinder optionally racks a selected number of needles in both directions each time and racks the yarn carrier, a wide variety of intasha designs in a single knit jersey knitted fabric can be knitted by the apparatus and method of the present invention. For racking purposes, the carrier may be a ring gear, a pinion and a step motor, for example, a ring gear 240, a pinion 242 and a step motor 246 (FIG. 3, 3a), a ring gear 246 and a worm Gear 268 (FIGS. 3B, 3C) or other racking device or the like.

By simply racking the cylinder, a straight, diagonal, striated stripe design can be organized without racking the yarn carriers and without using two yarn guiders for the needle ends. If the Gothic collar's design, in addition to the stripe, is to be knitted in a jersey knitted fabric, the cylinder and yankerier racking together with the two yarn guiders for the needle stage of the present invention is a relatively expensive and expensive method of needle and jacquard devices. You can carry out the design without using it. The present invention is relatively inexpensive to build and maintain and does not require needle jacks, needle selection and complicated control. The method is not complicated and can be easily performed by an operator.
