Description

Knit design device

Technical field

The present invention relates to the knit design device for designing intarsia pattern.

Background technology

The knitted fabric of intarsia pattern uses the stocking yarn different to stocking yarn, normally color that each decorative pattern is different to be woven by straight-bar machines.In addition intarsia pattern and braiding thereof are widely known by the people.What inventor paid close attention to herein is sometimes on the border of intarsia pattern, hang the stocking yarn of adjacent decorative pattern with pinhock and inweave.If the yarn-feeding port stopped from adjacent decorative pattern inweaves when the braiding of other decorative patterns across the stocking yarn to knitted fabric, then original stocking yarn and the stocking yarn of hook become 2 layers, and decorative pattern becomes not distinct.

Figure 11 illustrates this problem.If the not shown cam carrier of straight-bar machines moves from figure from left to right, cam carrier possesses a pair cam system in the front and back of direct of travel.Herein, if the cam system in the direct of travel front of cam carrier uses stocking yarn 41 to weave the decorative pattern in the left side of Figure 11, the cam system at direct of travel rear uses stocking yarn 42 to weave the decorative pattern on the right side of Figure 11.The pin 40 on the border of decorative pattern is assigned to the decorative pattern on right side in Last row, and this row is assigned to the decorative pattern in left side.Pin 40 forms the last coil of decorative pattern on right side in Last row, is therefore connected to the decorative pattern on right side from pin 40 from the stocking yarn 42 of yarn-feeding port 8.If from this state, operate the stocking yarn 41 from yarn-feeding port A by pin 40 and form coil, then have hour hands 40 hook stocking yarn 42 and be pulled in coil.

Figure 12 illustrates the relation between pin 40 now and stocking yarn 41,42.There is the coil 44 woven in the Last row of stocking yarn 42, be held in pin 40.Then stocking yarn 42 is entered to pin 40 side pressure by stocking yarn 41, easy hook.The coil configuration of the stocking yarn 41,42 when Figure 13 illustrates that stocking yarn 42 is hooked in pin 40.By the coil that the coil having marked label K3-2 is formed on pin 40, stocking yarn 41,42 forms 2 layer line circles, and therefore the color of coil is oozed out.In the frame in the left side of Figure 13 in addition, the operating space of pin is divided into lopping K and tuck T represents, the row of the line display cam carrier of frame.The arrow marked in the outside of frame represents the direct of travel of cam carrier.

Stocking yarn 42 also not hook under above-mentioned situation, also have the situation that can weave well, Figure 14 illustrates coil configuration when weaving well.In addition according to the experience of inventor, the plane No. of loom is less, braiding speed is higher, then the hook of stocking yarn more easily occurs, and the precision of the stop position of yarn-feeding port is lower, then the hook of stocking yarn more easily occurs.If illustrate relevant prior art herein, then patent document 1(Japan Patent 4163130) show following content: in embossing braiding, be divided into 2 of cam carrier rows to weave 1 of coil column row.Apply this technology, the coil on the right side of Figure 11 be divided into 2 rows and weave, when pin 40 does not keep stocking yarn 42 under the state of Figure 11, do not produce the problem of hook.But like this braid efficiency declines.

Summary of the invention

Problem of the present invention is, does not reduce braid efficiency and prevents the hook of the stocking yarn in the boundary portion of intarsia pattern.

The present invention is a kind of knit design device, generates the weave data be used at the intarsia pattern of fabric on flat knitting machine, it is characterized in that, comprising:

Detecting unit, for detecting if lower coil is as the first coil from weave data: weave the first knitted fabric leaning on the direct of travel rear of cam carrier relative to the border of intarsia pattern in the cam system in the direct of travel front utilizing the cam carrier of straight-bar machines, the cam system braiding at the direct of travel rear of cam carrier is utilized to lean in the row of second knitted fabric in the direct of travel front of cam carrier relative to described border, coil outstanding to the direct of travel front of cam carrier compared with the row just woven before in the coil of the end of described first knitted fabric, and

Weave data processing unit, when detecting the first coil, revise weave data as follows:

Second coil of the second knitted fabric be positioned at below 1 row relative to the first coil is replaced with flotation line,

Or the first coil is replaced with flotation line,

Or the first coil is replaced with the coil of the second knitted fabric.

When forming the first coil, hook is the stocking yarn connected to the second coil from yarn-feeding port.When second coil is changed into flotation line, the stocking yarn of hook is eliminated, and when forming the first coil, the situation of hook stocking yarn is eliminated.Then, when the first coil is changed into flotation line, in the coil above 1 row of the first coil, the moving direction of cam carrier is contrary with the first coil, does not therefore produce the problem of hook.This be due to, producing one of condition of hook is, utilize first knitted fabric at the cam system braiding direct of travel rear in the direct of travel front of cam carrier, utilize second knitted fabric in the cam system braiding direct of travel front at direct of travel rear, thus do not meet this condition.Same with the situation the first coil being replaced with flotation line, the coil the first coil being replaced with the second knitted fabric also can prevent the hook of stocking yarn.The cam system in the direct of travel front of cam carrier is utilized to weave first knitted fabric at direct of travel rear, utilize the condition of this generation hook of the second knitted fabric in the cam system braiding direct of travel front at direct of travel rear this is because, can not meet in this situation.As previously discussed in the present invention, the situation of hook stocking yarn when eliminating formation the first coil, and do not need to reduce braiding speed.

Preferably, when detecting the first coil, the second coil is replaced with flotation line.Like this, because the first coil connects multiple coil along coil line direction, so can obtain following effect: even if when the second coil also connects multiple coil along row direction, the length of the tuck between the decorative pattern of connection embossing does not also increase.Preferably, when detecting unit detects following situation from weave data, weave data processing unit correction weave data: with the first coil for benchmark, the yarn-feeding port supplying the straight-bar machines of the stocking yarn of the second knitted fabric is positioned at direct of travel along cam carrier to the position of next coil supply stocking yarn.Like this, the possibility that whether there is the hook producing stocking yarn can more reliably be differentiated.In addition, in this description, when relating to coil, row refers to the row of the coil of the width (reciprocating direction of cam carrier) along knitted fabric.When relating to cam carrier, row refers to the movement in the knitting width direction along cam carrier.Stringer is perpendicular to the direction of the row of coil, is the direction of knitting length.

Detailed description of the invention

Optimum embodiment for carrying out an invention below is shown.Scope of the present invention should add the possibility based on the change of prior art and explain in the record of claim.

[embodiment]

Embodiment shown in Fig. 1 ~ Figure 10 and distortion thereof.Fig. 1 represents the structure of knit design device 2, and 4 is bus, and 6 is colour picture monitor, and 8 is printer, and 10 is pen, the position on input picture, scope etc.Also pen 10 be can replace and control stick, trace ball, mouse etc. used.12 is keyboard, and 14 is network interface, and 16 is external memory drive.

Knit design device 2 is made up of computer, possesses CPU20 and memory 24.Input processing portion 22, weave data handling part 26, test section 28 are by CPU20 and the realization such as memory 24 and not shown program.Input processing portion 22 processes the design of knitted fabric of the intarsia pattern from the input such as pen 10, keyboard 12, the design obtained is converted to such as color code etc. and is stored in memory 24.The design data of memory 24 converts to by weave data handling part 26 can by the weave data of cross machine knitting.In addition weave data is made up of the data of annexation, the control data of cam carrier and the control data of yarn-feeding port etc. between the kind of the arrangement and coil that comprise coil, coil.The control data of yarn-feeding port such as makes which yarn-feeding port from which position linkage by cam carrier, which position to remove the data of interlock in.Test section 28 detection in the knitted fabric of intarsia pattern can produce the position of the hook of stocking yarn, and after this position being detected, weave data handling part 26 revises weave data to avoid producing the hook of stocking yarn.

Fig. 2 schematically represents the knitted fabric 30 of intarsia pattern, and knitted fabric 30 is made up of these 2 kinds of decorative patterns of A, B.As shown in Figure 3 straight-bar machines 32 making knit fabric 30 when, from the multiple cam systems 35 being located at cam carrier 34, such as, when weaving from the from left to right of Fig. 2, the cam system C1 in the direct of travel front of cam carrier 34 is assigned to decorative pattern A, the cam system C2 at rear is assigned to decorative pattern B.During braiding left from the dextrad of Fig. 2, the cam system C2 in the direct of travel front of cam carrier 34 is assigned to decorative pattern A, the cam system C1 at rear is assigned to decorative pattern B.In addition 36,36 of Fig. 3 is a pair, front and back needle-bars, and 38 is thread-carrier tracks, is the track guiding not shown multiple yarn-feeding ports.And yarn-feeding port passes through cam carrier 34 interlock via such as not shown linkage pin.

When cam carrier 34 moves from the from left to right of Fig. 2, there is the situation by the decorative pattern A position outstanding to decorative pattern B side.Now, the cam system C1 in the direct of travel front of cam carrier 34 first weaves and compares the decorative pattern A of decorative pattern B by direct of travel rear.Under this situation, when forming the coil at the decorative pattern A position outstanding to decorative pattern 8 side, easily produce the hook of stocking yarn.In Fig. 2, when cam carrier moves from right to left, also easily produce the hook of stocking yarn at the position that decorative pattern A is outstanding to decorative pattern B side.

The process of the hook for preventing the stocking yarn in embodiment is represented in Fig. 4, Fig. 5.Below, identical with the prior art of Figure 11 ~ Figure 13 label represents identical implication.When using stocking yarn 41 to form coil by pin 40, the hook of stocking yarn 42 becomes problem.In embodiment, the pin 40 that can go wrong does not weave (formation flotation line) to avoid the formation of coil before 1 row.So the configuration of yarn-feeding port 8 shifts 1 pin to the right from pin 40 as shown in Figure 4, consequently, when utilizing pin 40 to use stocking yarn 41 to weave, the hook of stocking yarn 42 is not produced.Fig. 5 illustrates the state of pin 40 now, and stocking yarn 42 is separated from pin 40, and is not entered to pin 40 side pressure by stocking yarn 41, is therefore difficult to introduce to pin 40.

Fig. 6 represents that the hook of stocking yarn becomes the position of problem and the flow process of stocking yarn around thereof.The label K3-2 of Fig. 6 represents and is equivalent to the first coil in claims by the coil of the second stringer from left to right in the 3rd row from lower.Position under 1 row of coil K3-2 is flotation line, does not form coil.The position of the flotation line under 1 row is the position of the second coil in claims.The knitted fabric utilizing stocking yarn 41 to weave is the first knitted fabric in claims, and the knitted fabric utilizing stocking yarn 42 to weave is the second knitted fabric.And represent the moving direction of cam carrier with the arrow in the left side of Fig. 6, K represents lopping, and T represents tuck.In the frame in the left side of Fig. 6, compare the keep left coil of side of longitudinal two-wire bar and utilize cam system C1 to be formed, coil on the right side utilizes cam system C2 to be formed.

In the initial row of Fig. 6, the second knitted fabric such as weaves 3 coils, and in next row, cam system C1 does not weave (flotation line) in the position of the second coil, and cam system C2 utilizes stocking yarn 41 to form tucked loop T1.Then cam carrier reverses and moves from the from left to right of figure, coil K3-2 etc. is formed by cam system C1, on the coil by the overlapping tucked loop T2 of the cam system C2 of rear movement, last row forms coil and the tucked loop T3 of 4 coils.Then by tucked loop T1 ~ T3, the first knitted fabric and the second knitted fabric are linked.What produce the hook of stocking yarn is the position of coil K3-2, but immediately below position be flotation line.Therefore, when forming coil K3-2, yarn-feeding port B is positioned at the position on the right side of the pin forming coil K3-2, does not produce the hook of stocking yarn.

Fig. 7 illustrates the example of the design of intarsia pattern, belongs to decorative pattern A at the borderline coil 45(of decorative pattern A, B) be the coil that can produce hook.In addition the moving direction of cam carrier is represented by arrow, coil 45 belongs to decorative pattern A, outstanding to decorative pattern B side at the position decorative pattern A of coil 45, now cam carrier moves from decorative pattern A to decorative pattern B side, utilize the cam system weave pattern A in the direct of travel front of cam carrier, utilize the cam system weave pattern B at direct of travel rear.When meeting these conditions, produce the hook of the stocking yarn in Figure 11.

Fig. 8 illustrates the correction of the weave data in embodiment, and arrow represents the moving direction of cam carrier, below equally.The coil immediately below coil 45 is made to change to (belonging to the coil of decorative pattern B) coil 46 of flotation line.The hook of stocking yarn can not be produced thus.

Fig. 9 illustrates variation, and the coil making the hook of stocking yarn become problem changes to the coil 46 of flotation line.Then, on the coil on the upside of 1 row of coil changing to flotation line, the direct of travel of cam carrier becomes contrary, does not therefore produce the hook of stocking yarn.

Figure 10 illustrates the second variation, and the coil 45 making the hook of stocking yarn become problem changes to the coil of decorative pattern B.So decorative pattern A is outstanding to decorative pattern B by the coil directly over coil 45, but when forming this coil, same with Fig. 9, the direct of travel of cam carrier becomes contrary, does not therefore produce the hook of stocking yarn.

The embodiment of Fig. 8 and the variation of Fig. 9 are along in the coil 46 continuous print situation of the multiple flotation line in row direction, different in the easiness of the tuck between the decorative pattern connecting intarsia pattern.In the embodiment of Fig. 8, from the coil of the decorative pattern A of the lower-left of the coil 46 of flotation line to the coil tuck of the decorative pattern B of the below of the coil 46 of flotation line, though the coil of flotation line 46 on row direction continuously, the length of tuck does not also increase.In the variation of Fig. 9, to the coil tuck of the decorative pattern B of the upper right of the coil 46 of flotation line from the coil of the decorative pattern A of the left of the coil 46 of flotation line.Therefore, the coil 46 of flotation line is along row direction consecutive hours, and the length of tuck increases.In second variation of Figure 10, owing to easily producing hook, from changing the coil of left of affiliated coil 45 to decorative pattern B to the coil tuck of the decorative pattern B of the upper right of coil 45.Therefore coil 45 along row direction multiple coil consecutive hours, the length of tuck increases.

As previously discussed in embodiment, do not reduce braiding speed, do not need the stop position critically controlling yarn-feeding port, just can on the border of intarsia pattern, prevent the stocking yarn hook of adjacent decorative pattern and inweave.The particularly plane No. hour of loom, the stocking yarn of the decorative pattern that easy hook is adjacent on the border of intarsia pattern, therefore Be very effective.Knit design device suitably can revise weave data automatically in addition.
