Abstract
Configuration: A knitted fabric having a plurality of triangular parts is designed so that the knitted fabric is knittable on a flat knitting machine. An external shape (30, 50) of a knitted fabric is input, the position of a center (C) at which apexes of respective parts into which the knitted fabric is divided gather is input, and the number of parts is determined. The knitted fabric is divided into a plurality of parts, each part having the shape of a triangle, the center (C) being the apex of the triangle, a peripheral edge of the knitted fabric being the base of the triangle, and lines connecting both ends of the base to the center (C) being the two sides of the triangle. Assuming that the peripheral edge of the knitted fabric is set in the course direction of knitting, whether the number of stitches corresponding to the length (d) of the base of each part can be decreased during knitting of the number of rows corresponding to the height (h) of that part while satisfying a condition of decrease is evaluated. If it is evaluated that the decrease is not possible, the number of parts is increased, or the base of the part is shortened. Then, flechage lines (60) are produced so as to be parallel to the course direction so that the difference in the number of rows between the two sides of each part due to a difference between lengths of the two sides is compensated for by flechage knitting that turns back in that part, and decrease courses are produced so that the same number of stitches as the number of stitches of the base are decreased. Effects: A knitted fabric that is knittable can be substantially automatically designed even in the cases of a knitted fabric having a complicated external shape and a knitted fabric whose center (C) is shifted from the center of its external shape.
Description
Technical field
The present invention relates to possess the design of the braided fabric of multiple contact pin of bringing together towards center.
Background technology
In the design of the complex-shaped braided fabric such as circular, oval, use leg-of-mutton contact pin, make the shape approximation of braided fabric.For example, at patent documentation 1(WO2009/022535) in, disclose circular-arc braided fabric has been divided into multiple contact pin, the situation from periphery towards center braiding.And if narrow in the process of braiding, knitting width gradually reduces towards center, braided fabric becomes circle.In addition, if take up one's knitting from the periphery of braided fabric, the base of contact pin is in periphery, and to walk crosswise direction parallel with the coil of braided fabric.
But, in the braiding of women's jacket, shawl etc., exist and wish the situation of contact pin towards the braided fabric brought together of the excentral position of circle.In addition, also exist and wish it is not circular, but the situation of oval-shaped braided fabric.So, contact pin is not isosceles triangle, and the shape of contact pin is also non-constant.Because if not isosceles triangle, the number of turns of wale direction is in two lateral plate differences, so, only, by narrowing, can not weave contact pin.Have again, the coil of the number of turns amount on the base of narrowing, wale direction need to the corresponding number of turns of the number of turns of narrowing.This be because, for example there is every 4 coils to walk crosswise to carry out the restriction of walking crosswise etc. with narrowing coil together for 1 time, be difficult to walk crosswise and narrow at whole coils.If the shape of contact pin is non-constant, also there is the situation that is not present in wale direction with the corresponding number of turns of the number of turns on base.Due to these, the design of contact pin becomes difficulty, is also difficult to carry out the design of braided fabric.

Detailed description of the invention
Represent the most preferred embodiment for carrying out an invention below.
Embodiment
Fig. 1～Figure 15 represents embodiment.Fig. 1 represents the knit design device 2 of embodiment, and knit design device 2 is made up of computer, possesses bus 4.The 6th, input part, at least possesses the manually input part such as mouse, keyboard, trace ball, stylus, in addition, also can possess the input part of automatic network, from the input part of moveable magnetic disc etc.The 8th, efferent, is to the efferent of network or to the efferent of moveable magnetic disc.The 10th, display, shows the braided fabric of design process etc., the 12nd, and color printer, the 14th, program internal memory, storage is for making computer bring into play the program of function as knit design device 2.
If specifying the profile He Qi center of braided fabric from input part 6 is the position that the summit of multiple contact pin is collected, further specify the sheet number of contact pin, contact pin generating unit 16 generates multiple contact pin, to braided fabric is divided into the multiple contact pin that are made up of triangle.In addition, in shawl etc., in the hole of aforesaid center in collar hole etc., so, the situation that exists center itself not weave.In this case, for example, generate contact pin, to wrap pin (Japanese original text: volt order) along the surrounding in hole.Therefore, exist actual contact pin shape to become along hole and will near the summit of 3 dihedrals, cut the situation of the trapezoidal shape that wraps pin.
The profile of braided fabric is not limited to circle, can be also polygon oval or as shown in Figure 14.In addition, the center that the summit of accessory is collected, in the case of the braided fabric for circular, can specify in the position that Cong Yuan center departs from.In the situation that being oval, be not limited to intersection point or the focus of oval major axis and minor axis, for example, the suitable position of being specified on oval major axis by operator becomes aforesaid center.Zhong of the present invention center is not the center with respect to the shape of the figure of braided fabric, and refers to the position that the summit of multiple contact pin is collected.
The shape of contact pin, in the situation that being oval-shaped braided fabric, departs from from isosceles triangle, even circular braided fabric, Cong Yuan center, Ruo Shi center is removed, and also departs from from isosceles triangle.Contact pin generating unit 16 for example waits certain angle to mark radially multiple lines towards the periphery of braided fabric from the center of braided fabric with 45 °～30 °.These lines are borders of contact pin, become two lateral plates of contact pin, and the periphery of the braided fabric of being divided by these lines is the base of contact pin.In the situation that there is major axis or diameter in braided fabric, preferably center is specified on these axles, preferably braided fabric is divided into 2 along these axles, the braided fabric that is divided into 2 is divided into respectively to multiple contact pin.Braided fabric with respect to these axisymmetric situations under, if contact pin is configured axisymmetrically with respect to these, only a side who is divided into 2 braided fabrics is processed.In addition, if braided fabric is divided into 2 along major axis, major axis doubles as the side into contact pin.
Contact pin evaluation section 18 is converted into the length on the base of contact pin coil and walks crosswise the number of turns of direction, the altitude conversion of contact pin is become to the number of turns of wale direction.And, evaluate during the side of braiding contact pin the number of turns on the base of the contact pin of can narrowing.For narrowing, have by every 4 coils and walk crosswise in preferred conditions such as each narrowing 2 circles in the left and right of contact pin, contact pin evaluation section 18 evaluates whether meet this condition.The number of turns of wale direction is the quantity of the coil along wale direction till to the limit from the base of contact pin.Meet the condition of narrowing in the case of not being evaluated as by contact pin evaluation section 18, contact pin generating unit 16 changes shape or the sheet number of contact pin, to meet the condition of narrowing, is again evaluated the condition that whether meets narrowing by contact pin evaluation section 18.
The handling part 20 that the turns back line (line of the braiding of turning back) that makes to turn back is walked crosswise direction along coil and is not limited in 1 contact pin, produces abreast but walk crosswise direction with coil in braided fabric.If because contact pin is not isosceles triangle, the number of turns of two lateral plates is inconsistent, so, by the braiding of turning back of carrying out in the way of contact pin or turn back in the end of contact pin, even if the number of turns of two lateral plates is inconsistent, also can weave contact pin.In addition, 1 line turning back is equivalent to the braiding that 2 coils are walked crosswise, and the braiding of turning back is called and turns back merely.The number of turns of the wale direction of line from multiple contact pin of turning back is that maximum lateral plate pulls out towards minimum lateral plate, and the great majority of the line that turns back turn back after by multiple contact pin.As actual braiding, 1 line that turns back is equivalent to the braiding that 2 coils that online end point turns back are walked crosswise, and in addition, also can turn back in the end of contact pin.
The line that preferably turns back roughly produces equably along the wale direction of braided fabric.In addition, in this manual, roughly generation or configuration are narrowed equably, and coil is walked crosswise and the line that turns back is to be configured to can not feel the inhomogeneous in appearance meaning.The quantity that the number of turns of wale direction is not folded back line divides exactly, and in addition, the situation that the quantity of also not walked crosswise by narrowing coil divides exactly is a lot.Therefore, be difficult to fully configure equably.
Narrowing handling part specifies narrowing coil to walk crosswise (coil of narrowing is walked crosswise) with respect to each contact pin.In addition, the position that narrowing coil is walked crosswise also can be in the contact pin difference of adjacency, and this point is different from the line that turns back.In addition, the coil of preferably narrowing is walked crosswise and is configured in contact pin roughly evenly along wale direction, and avoids the line that turns back.2 circle narrowings of each 2 circles are for example preferably walked crosswise in narrowing at every 4 coils in the left and right of contact pin.For example, the number of turns on the base of leg-of-mutton contact pin is 80 circles, is highly 20 circles, and the top of contact pin is cut away and done in echelon, and on the top (trapezoidal top) of contact pin, walking crosswise direction at coil has 4 circles.And, from the base of contact pin till the height on top is 19 circles (they being 20 circles to the limit).If during braiding 19 coils are walked crosswise, narrowing 76 circles, become at whole coils and walk crosswise and narrow, and are difficult to weave.
Because each 2 circles in left and right are aggregated in 1 coil and walk crosswise the narrowing of carrying out 4 circles, turn back by 1 time, braiding 2 coils are walked crosswise, so, preferably generating when contact pin, by the position of the dual-side of contact pin generating unit correction contact pin, so that making the difference of the number of turns of dual-side is even number, the multiple that the number of turns on base is 4.
Other handling part 24 carries out other processing relevant with braiding, for example, and the processing taking up one's knitting; Braiding finishes to wait appending of the bag pin that need to wrap in the situation of pin, texture pattern, intarsia designs etc.; Be body sheet at braided fabric, the designs of the sleeve of two have sleeve in the situation that etc.Data transaction portion 26, after the design of braided fabric completes, is converted to the design data of braided fabric the weave data that can be carried out by horizontal volume machine.
With reference to Fig. 1～Fig. 9, especially Fig. 2, illustrates the design of braided fabric.In addition, the design data of the braided fabric in design process is always presented at the display 10 of Fig. 1.Operator inputs the profile (step 1) of braided fabric from input part 6, the center that the summit of contact pin is collected is for example input on the major axis of braided fabric, the quantity (step 2) of input contact pin.Fig. 3, Fig. 4 represent with respect to the contact pin 32～39 of the profile 30 of identical braided fabric and contact pin 42～49.A-A is the major axis of the profile 30 of braided fabric, in Fig. 3, centered by the C of position, in Fig. 4, centered by the C ' of position.Contact pin 32～35 and contact pin 36～39 symmetries, contact pin 42～45 and contact pin 46～49 are also symmetrical.Change from C to C ' at Ruo Jiang center, the change of shape of contact pin, and center is removed greatlyr from the mid point of major axis, and the shape of contact pin is more inhomogeneous, and contact pin departs from from isosceles triangle.In addition, also can be as the C of Fig. 4 ", center is departed from from major axis A-A of braided fabric.In addition, the dotted arrow of Fig. 3, Fig. 4 represents the direction (wale direction) of braiding, and the periphery of the profile 30 of braided fabric is braiding top.In an embodiment, represent tubular knitted with respect to major axis A-A symmetry, but also can not carry out tubular knittedly, and for example carry out from Fig. 3, Fig. 4 to first-class knitting and forming.
If the profile of braided fabric determined, the sheet number of the position at center and contact pin is determined, generates contact pin by contact pin generating unit 16.For example, the drift angle of contact pin is cut apart the inside of profile 30 publicly, made multiple contact pin, obtain length d and the height h on the base of each contact pin, be converted into the number of turns on base and the number of turns of short transverse.In addition, require operator to input close direction (make contact pin near so that the direction that the summit of each contact pin is collected) (step 3).In addition, in the case of the sheet number of not inputting contact pin, sheet number that also can be using the standard values such as 8～12 as contact pin.In addition, in the case of not inputting close direction, also can according to make near in the summation of distance of the barring-on condition such as diminish, automatically generate close direction.
Contact pin evaluation section 18 is evaluated one side whether and meets the condition of narrowing, and one side makes the coil on the base of the contact pin center (step 4) of narrowing.(step 5) in the case of not meeting the condition of narrowing, changes the border of contact pin, to increase the quantity of contact pin or shorten the base that does not meet the contact pin of the condition of narrowing.If increase the quantity of contact pin, can more correctly make the periphery of the curve such as circle, ellipse approximate, still, need to make becomes each 1 narrowing of enclosing etc. in the narrowings of each 2 circles of the both sides of contact pin, has the situation that braid efficiency is low.
Fig. 5 a) in, the major axis A-A of profile 50 that by operator, center C is specified in to braided fabric is upper, generates multiple contact pin at Fig. 5 in b).Contact pin is generated as in the contact pin 51,55 contacting with major axis A-A, to make drift angle be α/2, in other contact pin 52～54, making drift angle is α, contact pin 51 '～55 ' with contact pin 51～55 for major axis A-A symmetry.Represent the height of contact pin with h, represent the length on base with d.Fig. 5 c) in, if specify close direction, for example, be designated as the position of close center b, move near the Xiang Gai position, summit that is designated as each contact pin, the arrow of Fig. 5 in c) is close direction.In the case of not inputting close center b, for conditions such as minimums, specify close center b by contact pin generating unit 16 according to the summation of the close distance in the summit that makes contact pin.In addition, close center b is used to specify the point that makes the close direction of contact pin, how to specify close center b to have impact to weaving easy degree.And, no matter where close center b is specified in, if depart from from horizontal volume machine, summit that braided fabric is also deformed into contact pin is collected to the center C of having specified in the step 2 of Fig. 2.
The condition that has met narrowing in all contact pin, as Fig. 6 a) as shown in, along the roughly configuration line that turns back equably of wale direction.Line 60 in the circle of the upper right quarter of figure is the lines that turn back, for example, from the right-hand member of contact pin 53 towards contact pin 54 sides.The quantity of the line that turns back turning back in contact pin is substantially equal to the poor ÷ 2 of the number of turns of the dual-side of contact pin.As shown in the circle of right median portion, the braiding walked crosswise by 2 coils of turning back forms, and the next wale that turns back between, produce the number of turns poor of 2 circles, therefore, at the end position of line that turns back, for example, substitute knittingly, carry out the tuck (step 6) of 1 circle.
The coil of narrowing is walked crosswise to (narrowing coil is walked crosswise) and be roughly configured in equably each contact pin along wale direction, the coil of the number of turns amount on base is by the center of narrowing (position that the summit of contact pin is collected).Walk crosswise and be not suitable for barring-on because carried out the coil of tuck, so the coil that preferably makes to have been undertaken by turning back tuck is walked crosswise from narrowing coil and walked crosswise eliminating.Fig. 6 b) represents narrowing line (narrowing circle the row along wale direction) 62.If make each contact pin close along close direction on display 10, become Fig. 6 c) such, the 64th, a needlework of the periphery of profile.
Will be to the additional three-dimensional shape of braided fabric, for example protuberance, as long as increase the length (number of turns of wale) of wale compared with the design of the braided fabric of plane.In addition, in the situation that collar hole etc. is arranged on to center, need only along collar hole each contact pin bag pin.Such example is illustrated in Fig. 7, adds three-dimensional shape by increasing coil along wale direction, and collar hole is set.
The top view of the shawl corresponding with the design of the contact pin of Fig. 7 is Fig. 8, and Fig. 9 is side view.The 80th, shawl, the 82nd, collar hole, r is its radius, the 84, the 84th, the precalculated position in arm hole, although be to arrange by cutting etc. after braiding, also can realize by knitting and forming.As described above, (step 8) of Fig. 2, in step 9, is converted to the weave data of horizontal volume machine in other the processing of input after contact pin.Horizontal volume facility have 2 above needle-bars, taking the major axis of braided fabric profile as boundary, weave a side, by rear needle-bar braiding the opposing party by front needle-bar.
Figure 10～Figure 13 is the design that represents carnival hat 90, and as shown in figure 10, the position of center C in skew, as shown in figure 11, has the protuberance of height h '.To this, by the order identical with Fig. 2, in side's configuration contact pin 91～95 of major axis A-A, configure contact pin 91 '～95 ' (Figure 12) the opposing party.Then, accordingly the region of having implemented hatched height h ' amount is appended to each contact pin (Figure 13) with protuberance.Later same with Fig. 2, can obtain the weave data of carnival hat 90.The 64th, play needlework.
Figure 14, Figure 15 represent the design of hexagonal braided fabric 100,101～106th, and contact pin, has symmetrical contact pin 101 '～106 ' in the opposition side of major axis A-A.If similarly design contact pin 101～105 with Fig. 2, become Figure 15 such, make contact pin 101～103 and contact pin 104～106 close as the arrow of figure.The 64th, play needlework.
Embodiment has feature below.
1) even if the braided fabric of removing from the center of profile for braided fabric and the center of complex appearance also can design the braided fabric that can weave.
2) if specify the profile of braided fabric and center, the sheet number of contact pin and the close direction (becoming the position of close center b) of the position collected as the summit of contact pin, can roughly automatically generate multiple contact pin, evaluation could be narrowed.In addition, can omit the sheet number of input contact pin and close direction.
3) even if contact pin is not isosceles triangle, also can weave.
4) because avoided the narrowing of turning back on line, so, do not exist because of with the narrowing barring-on together situation that the tuck of line departs from that makes to turn back.
5) because along wale direction approximate equality configure the narrowing coil line of walking crosswise and turn back, so the outward appearance of braided fabric is good.In addition, even in the situation that collar hole etc. is set, keeps intact and use the narrowing till collar hole and turn back, there is no need to configure again the narrowing coil line of walking crosswise and turn back.
6) Ruo Jiang center specifies on the major axis of braided fabric, if to a side of major axis carry out contact pin generation, narrow, turn back, near etc., the design data obtaining is copied to the opposing party of major axis.
7) braided fabric can be at random the clothes such as women's jacket, shawl, place mat fabric etc.In addition, can be also the braided fabric with the part beyond the part that formed by contact pin and contact pin.
