Description

The present invention relates to a jacquard russell machine and a knitting method capable of obtaining a lace knitted fabric having a heavy texture by rough knitting using a thick yarn at a low cost.

A typical jacquard russell machine forms a plurality of wales by vertically knitting a plurality of warp yarns supplied by a ground warp with a knitting needle, etc. A net-like ground structure is formed by inserting each wale while being swung in the lateral direction by cam driving and connecting them to each other. Then, by shifting (acting) the guide through the insertion thread in the lateral direction at an appropriate timing, two adjacent insertion threads can be partially overlapped, and further, the handle thread supplied by the handle can be inserted. As a result, a knitted lace fabric with varying fabric thickness and through hole shape is knitted.
The ground texture is knitted with a uniform gauge over the entire width. For example, in the case of 24 gauge, 24 knitting needles are arranged per inch on the needle bed, and 24 guides are arranged per inch on each heel.
When the jacquard jar is composed of multiple sheets (for example, two front and back), pass the guides back and forth (1 in 1 out) so that the insertion threads do not overlap when viewed from the front, so-called half set. Therefore, the entire jacquard is designed to have 24 insertion threads per inch.
The thickness of the warp / insertion yarn to be used is restricted by the number of gauges (interval between adjacent knitting needles and guides) and the swing width of the reed. The larger the gauge number, the tighter the knitting because thinner yarns are used, and the higher the lace knitted fabric, which is generally thin and delicate.

  Thus, for example, in the knitting method of a lace knitted fabric disclosed in Patent Document 1, a basic knitting needle bed and an extended knitting needle bed are mixed in the needle bed and an extension gauge ridge is provided. In the ground structure where the interval between the wales is coarse, the handle thread is more likely to be loosened than the dense ground structure, the handle thread is lifted and the inserted thread is loosened, and the gap between the wales is coarse and thick. Insertion thread can be used. As a result, it is possible to obtain a knitted lace fabric with a heavy texture and partially different fabric thickness.

  However, the technique described in Patent Document 1 has a problem that the manufacturing cost increases because the structure of the knitting machine needs to be significantly modified.

In view of the above problems, an object of the present invention is to provide a jacquard russell machine and a knitting method that can obtain a lace knitted fabric having a heavy texture by rough knitting using a thick yarn at a low cost.

Jacquard Russell machine of the present invention, the needle bed, ground guide bars, jacquard reed, in jacquard raschel machine including a cam for controlling lateral swing motion of the jacquard reed, the needle n the (n per inch on the floor 12) , 14) , or 18) is arranged, and warp yarns are passed through the guide of the ground rod at a rate of n per inch corresponding to the knitting needle, and n per inch of the guide of the jacquard rod. through insertion yarns at a ratio of this, said by the driving cam is operated jacquard reed the two stitches between partial lateral swing, by 0.5 needles between partial displacement of the jacquard reed guide at any time, the guide The insertion yarn passed through is hung on an adjacent knitting needle .
Knitting method of the present invention, the needle bed, ground guide bars, jacquard reed, keep knitting method according jacquard raschel machine including a cam for controlling lateral swing motion of the jacquard reed, per inch n present on the needle bed ( n is one of 12, 14, and 18) , the warp thread is passed through the guide of the ground rod at a rate of n per inch corresponding to the knitting needle, and 1 inch is passed through the guide of the jacquard rod. through insertion yarns at a rate per n present, wherein the driving cam is operated jacquard reed the two stitches between partial lateral swing, by any displacement amount between 0.5 needles the jacquard reed comprises guide timing The insertion yarn passed through the guide is hung on an adjacent knitting needle .

In the present invention, the jacquard rod is swung by the distance between two stitches by driving the cam, and the guide of the jacquard rod is displaced (acted) by 0.5 stitches at an arbitrary timing. When the jacquard ガ イ ド guide and the insertion thread are displaced (actuated) by 0.5 stitches while the jacquard 横 is moved sideways by 2 stitches, the guide that was not displaced (actuated) on the adjacent wales. The two insertion threads, the insertion thread of the guide and the insertion thread of the displaced (actuated) guide, can be overlapped and inserted. Thereby, the thickness of the cloth, the shape of the through holes, and the like can be changed.
If the needle bed, ground and jacquard basins are configured with half the number of gauges (for example 24, 28, 36 gauges) of existing jacquard russell machines (n = 12, 14, 18), the guide interval will be reduced. Since it is possible to use thick yarn by expanding it, the jacquard kite can be diverted as it is, so that a knitted lace fabric with a rough texture and a heavy texture can be obtained at low cost.

Embodiments of the present invention will be described below with reference to the drawings.
The jacquard russell machine of the present invention is provided with a needle bed, a ground pad, a jacquard paddle, and a cam. The feature of the present invention is that a lace knitted fabric having a heavy texture can be obtained at a low cost by rough knitting using a thick yarn based on an existing jacquard russell machine without significant modification. is there. Therefore, the detailed description regarding the structure of a Jacquard Russell machine is omitted. This embodiment is based on an existing 24-gauge Jacquard Russell machine.
As shown in FIG. 1, n knitting needles N are arranged per inch on the needle bed. In this embodiment, n = 12, that is, a 12 gauge configuration, but using a needle bed of an existing 24-gauge Jacquard Russell machine, 12 knitting needles per inch may be arranged on this needle bed. .

  The ground guides are threaded at a rate of n = 12 per inch, corresponding to the knitting needles. Using the ground of an existing 24 gauge Jacquard Russell machine, you only need to pass 12 warps per inch through this ground guide. In other words, it is only necessary to pass warps through 12 guides per inch for every other guide, instead of 24 guides per inch arranged on existing ground. FIG. 1 shows chain-knitted meshes C1 to C4.

The insertion thread Y is passed through the guide of the jacquard jar at a rate of n = 12 per inch. The jacquard cage is controlled by the cam to control the amount of movement and the timing of its lateral movement. Each guide of the jacquard cage is displaced (acted) independently at any timing in the lateral direction by the jacquard mechanism. be able to.
As described above, in a general 24-gauge jacquard russell machine, when the jacquard kite is composed of two front and rear, for example, the insertion thread is half-set in a staggered manner (1 in 1 out) and 12 per inch. It is passed through the guide at the rate of the book, and when inserting two front and rear jacquard caskets in front, the insertion thread is 24 per inch. Therefore, one of the two front and rear jacquard cages used in a general 24-gauge jacquard russell machine may be directly used as the jacquard cage of the present invention.

The cam controls the amount of movement and the timing of movement of the jacquard basket.
Fig. 2 shows the lateral movement of the jacquard basket in an existing 24-gauge jacquard russell machine. Each guide and insertion thread of Jacquard 筬 is moved by approximately 1 stitch in the left-right direction by cam drive, and the guide and insertion thread are displaced (acted) by one stitch at any timing ( (Refer to dotted line A1 'in the 4th and 6th courses in Fig. 2), and by changing the insertion thread Y1' displaced and the adjacent insertion thread Y2 ', the thickness of the fabric and the shape of the through-holes can be changed. Yes.

FIG. 1 shows the lateral movement of the jacquard basket in the jacquard russell machine of the present invention. Each guide and insertion thread Y of the jacquard rod is moved laterally by the distance between the two stitches in the left-right direction in terms of 12 gauge by driving the cam.
The adjustment of the lateral movement of the jacquard can be easily performed by changing the shape of the cam. FIG. 3 (a) schematically shows the shape and drive of a cam (pattern wheel) in an existing 24-gauge Jacquard Russell machine. As shown in FIG. 3 (b), the amount of lateral movement of the follower 30 connected to the jacquard cage is increased by making the shape of the cam 20 rotating around the support shaft 10 higher than that of the existing cam 21. Can be changed from D1 to D2 (D1 <D2).
In the case of the insertion yarn indicated by reference numeral Y1, the insertion yarn Y1 is inserted into the second wale chain-knitted with a knitting needle of reference numeral N2 in the first course. Then, in the next second course, the insertion yarn Y1 moves laterally by the distance between two stitches in terms of 12 gauge, but since there is no knitting needle at this position, it is hooked on the knitting needle of the symbol N3 and chain knitting with the knitting needle N3. Inserted into the third wal. As a result, the adjacent second wales and third wales are connected by the insertion yarn Y1. In addition, since each insertion thread Y is adjusted so that an appropriate tension is always applied, the insertion thread Y does not sag.

The dotted line A1 in FIG. 1 indicates that one guide and the insertion thread Y1 are further displaced in the lateral direction in a state in which the guide and the insertion thread Y of the jacquard heel are moved in the lateral direction by two gauges in terms of 12 gauges ( The state of action) is shown. At this time, the displacement amount of the guide and the insertion thread Y1 is 0.5 stitches in terms of 12 gauge (one stitch in terms of 24 gauge). That is, the displacement L of the guide and the insertion yarn Y1 in the jacquard raschel machine of the present invention is the same as the displacement L of the guide and the insertion yarn Y1 ′ in the existing 24-gauge jacquard raschel machine shown in FIG. In this way, one of the two front and rear jacquard cages used in the existing 24-gauge jacquard russell machine can be used as it is as the jacquard cage of the present invention, and each guide of the jacquard cage can be displaced (action). The jacquard mechanism can be used as is.
The amount of movement of the guide and insertion thread Y in the lateral direction by cam driving is between the two stitches, and when the amount of displacement between 0.5 stitches is added to this, it moves by 2.5 stitches.
Since there is a knitting needle denoted by reference numeral N4 at a point where the insertion thread Y1 is displaced (acted) by 0.5 stitches in 12 gauge conversion in the horizontal direction, the insertion thread Y1 is hooked on the knitting needle N4 and chain-knitted with the knitting needle N4. Inserted into 4 wales. Further, since the insertion yarn indicated by the reference symbol Y2 is also hooked on the knitting needle N4 and inserted into the fourth wale, the insertion yarns Y1 and Y2 are overlapped, and the thickness of the fabric, the shape of the through holes, and the like can be changed. In the present invention, the needle bed, ground and jacquard rivets are composed of half the number of normal gauges (for example, 12 gauges (n = 12), which is half of 24 gauges). Spacing can be increased, coarse knitting using thick yarn can be realized, and a knitted lace fabric with a heavy texture can be obtained at low cost.

FIG. 4 shows a case where the amount of movement of the guide of the jacquard jar is slightly larger than that of FIG. In this case as well, both the insertion threads Y1 and Y2 can be inserted into the fourth wale by displacing (acting) the guide of the jacquard kite by 0.5 stitches (see dotted line A2).
As described above, in the present invention, “running the jacquard basket by two stitches” does not necessarily mean that the two jacquard baskets are pivoted accurately by two stitches. This means that when the heel guide is displaced by 0.5 stitches, the insertion thread is moved by approximately 2 stitches to the extent that it can be hooked on the adjacent knitting needle.
Moreover, in this embodiment, the needle bed, the ground and the jacquard basin are composed of 12 gauges (n = 12), which is half of the existing 24-gauge jacquard russell machine. Based on the existing 28 gauge or 36 gauge Jacquard Russell machine, the needle bed, ground and jacquard cage are composed of 14 gauge (n = 14) and 18 gauge (n = 18), which is half of that. May be. As a matter of course, the present invention can be applied to Jacquard Russell machines other than the existing 24, 28, and 36 gauges.
Further, a thick handle yarn may be inserted using a handle.

  The photograph in FIG. 5 is a knitted lace fabric knitted by the jacquard russell machine and the knitting method of the present invention. Compared to a typical lace fabric, it is a rough knitting using thick yarn, and it can be seen that it has a heavy texture.

The present invention relates to a jacquard russell machine and a knitting method capable of obtaining a lace knitted fabric having a heavy texture at a low cost by rough knitting using a thick yarn, and has industrial applicability.
