Abstract

The invention provides a knit design apparatus. In a course in which a cam system (C1) on the front side in the travelling direction of a carriage (34) of a flat knitting machine (32) knits a first knitted fabric (A) on the rear side in the travelling direction with respect to the boundary between intarsia pattern portions and a cam system (C2) on the rear side in the travelling direction knits a second knitted fabric (B) on the front side in the travelling direction with respect to the boundary. The knit design apparatus (2) detects from knitting data a stitch that is at an end of the first knitted fabric (A) and that projects further to the front side in the travelling direction than a course knitted immediately before, as a first stitch (K3-2, 45). In a case where the first stitch (K3-2, 45) is detected, a second stitch (46) in the second knitted fabric (B) positioned one course below the first stitch (K3-2, 45) is replaced by a miss stitch, thereby not reducing the knit efficiency while preventing the stocking yarn hooking on the boundary of the panel design.

Description

Knit design device

Technical field

The present invention relates to be used to design the knit design device of intarsia pattern.

Background technology

The knitted fabric of intarsia pattern uses the different stocking yarn of each decorative pattern, stocking yarn that normally color is different is woven through straight-bar machines.Intarsia pattern and braiding thereof are widely known by the people in addition.The inventor pays close attention to here is on the border of intarsia pattern, to hang the stocking yarn of adjacent decorative pattern with pinhock sometimes and inweave.If the yarn-feeding port that stops from adjacent decorative pattern is striden to the stocking yarn of knitted fabric and inweaved when the braiding of other decorative patterns, the then original stocking yarn and the stocking yarn of hook become 2 layers, and it is not distinct that decorative pattern becomes.

Figure 11 illustrates this problem.If the not shown cam carrier of straight-bar machines moves right from the figure left-hand, cam carrier possesses a pair of cam system in the front and back of direct of travel.Herein, establish the cam system in direct of travel the place ahead of cam carrier and use the decorative pattern in the left side of stocking yarn 41 braiding Figure 11, the cam system at direct of travel rear is used the decorative pattern on the right side of stocking yarn 42 braiding Figure 11.The pin 40 on the border of decorative pattern is assigned to the decorative pattern on right side on Last row, on this row, be assigned to the decorative pattern in left side.Pin 40 forms the last coil of the decorative pattern on right side on Last row, therefore be connected to the decorative pattern on right side from pin 40 from the stocking yarn 42 of yarn-feeding port 8.If begin from this state, form coil through pin 40 operations from the stocking yarn 41 of yarn-feeding port A, hour hands 40 hook stocking yarns 42 are then arranged and be pulled in the coil.

Figure 12 illustrates pin 40 and stocking yarn 41, the relation between 42 of this moment.Have the coil 44 that in the Last row of stocking yarn 42, weaves, remain in pin 40.Stocking yarn 42 is gone into to pin 40 side pressures by stocking yarn 41 then, easily hook.The coil configuration of the

stocking yarn

41,42 when Figure 13 illustrates stocking yarn 42 and is hooked in pin 40.Through the coil that the coil that has marked label K3-2 forms on pin 40,

stocking yarn

41,42 forms 2 layer line circles, so the color of coil is oozed out.In the frame in the left side of Figure 13 the operating space of pin is divided into lopping K in addition and tuck T representes, the row of the line display cam carrier of frame.The arrow of mark is represented the direct of travel of cam carrier in the outside of frame.

Also hook not of stocking yarn 42 also has the situation that can weave well under above-mentioned situation, and Figure 14 illustrates the coil configuration when weaving well.According to inventor's experience, the plane No. of loom is more little, braiding speed is high more in addition, and the hook of stocking yarn then takes place more easily, and the precision of the stop position of yarn-feeding port is low more, and the hook of stocking yarn then takes place more easily.If relevant prior art is shown, then patent documentation 1 (Japan Patent 4163130) shows following content here: in the embossing braiding, 2 rows that 1 row of coil column are divided into cam carrier weave.Application should technology, and the coil on the right side of Figure 11 is divided into 2 rows and weaves, and when pin 40 does not keep stocking yarn 42 under the state of Figure 11, does not produce the problem of hook.But like this braid efficiency descends.

Summary of the invention

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

The present invention is a kind of knit design device, generates the weave data of the intarsia pattern that is used on straight-bar machines, weaving, and it is characterized in that, comprising:

Detecting unit; Be used for detecting like lower coil as first coil from weave data: the cam system braiding in direct of travel the place ahead of the cam carrier that utilizes straight-bar machines with respect to the border of intarsia pattern lean on the direct of travel rear of cam carrier first knitted fabric, utilize the cam system braiding at the direct of travel rear of cam carrier to lean on the row of second knitted fabric in direct of travel the place ahead of cam carrier with respect to said border, in the coil of the end of said first knitted fabric with before just the row of braiding compare to the outstanding coil in direct of travel the place ahead of cam carrier; And

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

To replace with flotation line with respect to second coil that first coil is positioned at second knitted fabric of 1 row below,

Or first coil replaced with flotation line,

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

Hook is the stocking yarn that connects to second coil from yarn-feeding port when forming first coil.When second coil was changed into flotation line, the stocking yarn of hook was eliminated, and the situation of hook stocking yarn is eliminated when forming first coil.Then, when first coil was changed into flotation line, in the coil above 1 row of first coil, the moving direction of cam carrier was opposite with first coil, did not therefore produce the problem of hook.This be because; One of condition that produces hook is; Utilize first knitted fabric at cam system braiding direct of travel rear in direct of travel the place ahead of cam carrier, utilize second knitted fabric in the cam system braiding direct of travel the place ahead at direct of travel rear, thereby do not satisfy this condition.Same with the situation that first coil is replaced with flotation line, the coil that first coil is replaced with second knitted fabric also can prevent the hook of stocking yarn.This be because, can not satisfy under this situation the cam system braiding direct of travel rear in the direct of travel the place ahead that utilizes cam carrier first knitted fabric, utilize the condition of this generation hook of second knitted fabric in the cam system braiding direct of travel the place ahead at direct of travel rear.Among the present invention, eliminate the situation of hook stocking yarn when forming first coil as previously discussed, and need not reduce braiding speed.

Preferably, when detecting first coil, second coil is replaced with flotation line.Like this, because first coil connects a plurality of coils along coil line direction, so can obtain following effect: even connect under the situation of a plurality of coils along coil line direction at second coil, the length of the tuck between the decorative pattern of connection embossing does not increase yet yet.Preferably; At detecting unit when weave data detects following situation; Weave data processing unit correction weave data: with first coil is benchmark, and the yarn-feeding port of straight-bar machines of supplying with the stocking yarn of second knitted fabric is positioned at the position of next coil being supplied with stocking yarn along the direct of travel of cam carrier.Like this, can differentiate the possibility that whether has the hook that produces stocking yarn more reliably.In this specification, when relating to coil, row is meant the row of the coil of the width (reciprocating direction of cam carrier) along knitted fabric in addition.When relating to cam carrier, row is meant moving along the knitting width direction of cam carrier.Stringer is perpendicular to the direction of the row of coil, is the direction of knitting length.

Embodiment shown in Fig. 1～Figure 10 and distortion thereof.Fig. 1 representes 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, is used for position, scope etc. on the input picture.Also can replace pen 10 and use control stick, trace ball, mouse etc.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 handling part 22, weave data handling part 26, test section 28 pass through CPU20 and memory 24, reach not shown realizations such as program.Input handling part 22 is handled from the design of the knitted fabric of the intarsia pattern of inputs such as pen 10, keyboard 12, and the design that obtains is for example converted to color code etc. and is stored in memory 24.Weave data handling part 26 converts the design data of memory 24 to can be by the weave data of cross machine knitting.In addition weave data by the kind of arrangement that comprises coil and coil, between coil annexation, cam carrier control data, and the data of the control data of yarn-feeding port etc. constitute.The control data of yarn-feeding port is for example to make which yarn-feeding port from which position linkage through cam carrier, to remove at which position the data of interlock in.Test section 28 detects the position of the hook that can produce stocking yarn in the knitted fabric of intarsia pattern, detect this position after, weave data handling part 26 is revised weave datas to avoid producing the hook of stocking yarn.

Fig. 2 schematically representes the knitted fabric 30 of intarsia pattern, and knitted fabric 30 is made up of A, these 2 kinds of decorative patterns of B.Under the situation by straight-bar machines shown in Figure 3 32 making knit fabrics 30; From being located at a plurality of cam systems 35 of cam carrier 34; When for example weaving from the left-hand of Fig. 2 is right; The cam system C1 in direct of travel the place ahead of cam carrier 34 is assigned to decorative pattern A, the cam system C2 at rear is assigned to decorative pattern B.The cam system C2 in direct of travel the place ahead of cam carrier 34 is assigned to decorative pattern A from the dextrad of a Fig. 2 left side during braiding, the cam system C1 at rear is assigned to decorative pattern B.In addition the 36 of Fig. 3, the 36th, before and after a pair of needle-bar, the 38th, the thread-carrier track is the track of the not shown a plurality of yarn-feeding ports of guiding.And yarn-feeding port passes through cam carrier 34 interlocks via for example not shown linkage pin.

There is the situation to the side-prominent position of decorative pattern B through decorative pattern A in cam carrier 34 when the left-hand of Fig. 2 moves right.At this moment, the decorative pattern A that decorative pattern B leans on the direct of travel rear is compared in the cam system C1 in direct of travel the place ahead of cam carrier 34 braiding earlier.Under this situation, form decorative pattern A when the coil at the side-prominent position of decorative pattern 8, be easy to generate the hook of stocking yarn.Among Fig. 2, when cam carrier moves from right to left, also be easy to generate the hook of stocking yarn to the side-prominent position of decorative pattern B at decorative pattern A.

Expression is used for preventing the processing of hook of the stocking yarn of embodiment among Fig. 4, Fig. 5.Below, the label identical with the prior art of Figure 11～Figure 13 represented identical implication.When using stocking yarn 41 to form coil through pin 40, the hook of stocking yarn 42 becomes problem.Among the embodiment, the pin 40 that can go wrong does not weave (formation flotation line) to avoid forming coil before 1 row.Shift 1 pin so the configuration of yarn-feeding port 8 is as shown in Figure 4 to the right from pin 40, consequently, when utilizing pin 40 to use stocking yarn 41 to weave, do not produce the hook of stocking yarn 42.Fig. 5 illustrates the state of the pin 40 of this moment, and stocking yarn 42 separates from pin 40, and is not gone into to pin 40 side pressures by stocking yarn 41, therefore is difficult to introduce to pin 40.

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

Second knitted fabric for example weaves 3 coils on the initial row of Fig. 6, and cam system C1 does not weave (flotation line) in the position of second coil on next row, and cam system C2 utilizes stocking yarn 41 to form tucked loop T 1.Then cam carrier reverses and moves right from the left-hand of scheming; Form coil K3-2 etc. through cam system C1; The overlapping tucked loop T2 of cam system C2 that on this coil, moves through the back, the coil and the tucked loop T3 of 4 coils of formation on last row.Through tucked loop T1～T3, first knitted fabric and second knitted fabric are linked then.Produce stocking yarn hook be the position of coil K3-2, but under the position be flotation line.Therefore when forming coil K3-2, yarn-feeding port B is positioned at the position that connects to coil K3-3, does not produce the hook of stocking yarn.

Fig. 7 illustrates the example of the design of intarsia pattern, is the coil that can produce hook at the borderline coil 45 (belonging to decorative pattern A) of decorative pattern A, B.The moving direction of representing cam carrier in addition by arrow; Coil 45 belongs to decorative pattern A; Decorative pattern A is side-prominent to decorative pattern B in the position of coil 45; This moment, cam carrier to decorative pattern B side shifting, utilized the cam system weave pattern A in direct of travel the place ahead of cam carrier from decorative pattern A, utilized the cam system weave pattern B at direct of travel rear.When satisfying these conditions, produce the hook of the stocking yarn among Figure 11.

Fig. 8 illustrates the correction of the weave data among the embodiment, and arrow is represented the moving direction of cam carrier, below same.Make coil 45 under coil 46 (coil that belongs to decorative pattern B) change to flotation line.Can not produce the hook of stocking yarn thus.

Fig. 9 illustrates variation, and the coil 45 that makes the hook of stocking yarn become problem changes to flotation line.On the coil of 1 row upside of the coil that changes to flotation line, the direct of travel of cam carrier becomes on the contrary then, does not therefore produce the hook of stocking yarn.

Figure 10 illustrates second variation, and the coil 45 that makes 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 through the coil directly over the coil 45, but when forming this coil, same with Fig. 9, the direct of travel of cam carrier becomes on the contrary, so does not produce the hook of stocking yarn.

The embodiment of Fig. 8 and the variation of Fig. 9 are under the situation continuous along the coil of a plurality of flotation lines of coil line direction 46, different aspect the easy property of the tuck between the decorative pattern that connects intarsia pattern.Among the embodiment of Fig. 8, the coil of the decorative pattern A under the left side of the coil 46 of flotation line gets final product 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 the row direction continuously, the length of tuck does not increase yet.In the variation of Fig. 9, begin coil tuck to the upper right decorative pattern B 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 coil line direction consecutive hours, and the length of tuck increases.In second variation of Figure 10, owing to be easy to generate hook, the coil of the left of the coil 45 under changed to decorative pattern B is to the coil tuck of the upper right decorative pattern B of coil 45.Therefore coil 45 is along a plurality of coil consecutive hourss of coil line direction, and the length of tuck increases.

Among the embodiment, do not reduce braiding speed as previously discussed, do not need critically to control the stop position of yarn-feeding port, just can on the border of intarsia pattern, prevent the stocking yarn hook of adjacent decorative pattern and inweave.The plane No. of loom hour particularly, the stocking yarn of the decorative pattern that hook is adjacent easily on the border of intarsia pattern, so effect is remarkable.Knit design device can suitably be revised weave data automatically in addition.
