Description
Technical field
The present invention relates to the design of the braided fabric possessing the multiple contact pin collected 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.Such as, at patent document 1(WO2009/022535) in, disclose and the braided fabric of arc-shaped is divided into multiple contact pin, from the situation that periphery weaves towards center.And if narrow in the process of braiding, knitting width gradually reduces towards center, then braided fabric becomes circular.In addition, if take up one's knitting from the periphery of braided fabric, then 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., there is the situation of wishing the braided fabric that contact pin collects towards round excentral position.In addition, also exist and wish it is not circular, but the situation of the braided fabric of ellipse.So, contact pin is not isosceles triangle, and the shape of contact pin is also non-constant.Because if not isosceles triangle, then the number of turns in wale direction is different at two lateral plates, so, by means of only narrowing, can not contact pin be woven.The coil of the number of turns amount on base further, will narrow, needs the number of turns corresponding to the number of turns of carrying out narrowing in wale direction.This is because, such as there are every 4 coils and walk crosswise the restriction that execution 1 time and narrowing coil together walk crosswise etc., be difficult to walk crosswise at whole coil narrow.If the shape of contact pin is non-constant, then also there is the situation that the number of turns corresponding to the number of turns on base is not present in wale direction.Due to these, the design of contact pin becomes difficulty, is also difficult to the design carrying out braided fabric.

Patent document 1:WO2009/022535
Even if problem of the present invention is the braided fabric that the center collected for the braided fabric of the profile of complexity and the summit of accessory is removed from the center of profile, the design of braided fabric also easily can be carried out.
Summary of the invention
The invention provides a kind of knit design method braided fabric with multiple leg-of-mutton accessory being designed to be able to woven by flat knitting machine, it is characterized in that,
The profile of input braided fabric,
The position at the center that the summit inputting the accessory split by braided fabric is collected,
Determine the quantity of accessory,
By being summit by aforesaid center, the periphery of braided fabric is base, and multiple accessories that the triangle being dual-side by the line of the two ends on base and aforesaid central link is formed, braided fabric is split,
With the periphery of braided fabric for direction walked crosswise by the coil of braiding, evaluate and can weave the number of turns corresponding to the height of accessory, in other words, during the number of turns in the wale direction of accessory for each accessory, one side meets the condition number of turns that simultaneously narrowing is corresponding to the length on base of narrowing
When be evaluated as can not narrow, the base of the accessory that can not narrow is evaluated as by the quantity or shortening increasing accessory, can during the number of turns that braiding is corresponding to the height of accessory, one side meets the condition number of turns that simultaneously narrowing is corresponding to the length on base of narrowing
Then, walking crosswise direction with coil and produce the line that turns back abreast, so that the braiding of turning back by turning back at this accessory, correcting the difference of the number of turns caused by the length difference of the dual-side of accessory,
Produce narrowing coil to walk crosswise, so that the coil of the number of turns amount on base of narrowing.
In addition, the invention provides a kind of knit design device braided fabric with multiple leg-of-mutton accessory being designed to be able to woven by flat knitting machine, it is characterized in that possessing:
Input part, the profile of its input braided fabric and the position at center that the summit of accessory that braided fabric is split is collected;
Accessory generating unit, it generates is summit by aforesaid center, and the periphery of braided fabric is base, and multiple accessories that the triangle being dual-side by the line of the two ends on base and aforesaid central link is formed, braided fabric is split;
Accessory evaluation section, it is with the periphery of braided fabric for direction walked crosswise by the coil of braiding, and can evaluate during the number of turns that braiding is corresponding to the height of accessory for each accessory, the number of turns that the satisfied condition one side narrowing of narrowing of one side is corresponding to the length on base;
When be evaluated as can not narrow, be evaluated as the component on the base of the accessory that can not narrow for increasing the quantity of accessory or shortening;
Turn back handling part, and itself and coil are walked crosswise direction and produced the line that turns back abreast, so that the braiding of turning back by turning back in the inside of accessory or end, corrects the difference of the number of turns caused by the length difference of the dual-side of accessory; And
Narrowing handling part, it produces narrowing coil and walks crosswise, so that the coil of the number of turns amount on base of narrowing.
If the profile of input braided fabric, the position at the center that the summit inputting accessory is collected, then can split braided fabric by multiple accessory.Accessory is triangle, and the summit of accessory is collected to aforesaid center, and the periphery of braided fabric becomes the base of accessory, and, the line of the two ends on base and aforesaid central link is become dual-side.Because during needing till culminating, the coil of the number of turns that narrowing is suitable with the base of accessory, so, evaluate the condition one side that simultaneously can meet preferred narrowing and perform narrowing, in inexecutable situation, change shape or the quantity of accessory.If the center that the summit of accessory is collected departs from from the center of the profile of the braided fabric the meaning of figure, then accessory departs from from isosceles triangle.Therefore, the number of turns generation of the dual-side of accessory is poor, in order to correct this difference, walking crosswise direction produce the line that turns back turned back in the inside of accessory or end abreast with coil.In addition, produce narrowing coil and walk crosswise, so that the number of turns of the base amount of accessory of narrowing.In addition, when in order to collar hole etc. is set and the top of leg-of-mutton accessory is cut away do in echelon, can using the height of the height to the vertex of a triangle before cutting away as accessory, also can using the height of trapezoidal height as accessory.And, when using trapezoidal height as the height of accessory, the number of turns from base is deducted the number of turns after the number of turns of trapezoidal top as the number of turns of carrying out narrowing.
Therefore,
1) even if the braided fabric removed from the center etc. of circle of the profile becoming braided fabric of the center collected for the braided fabric of the profile of complexity and the summit of accessory, the braided fabric that can weave can also be designed.
2) if specify the profile of braided fabric and aforesaid center, then can roughly automatically generate multiple accessory, evaluation could be narrowed.
3) even if accessory is not isosceles triangle, also can weave.
In addition, in this manual, about knit design method record also former state be applicable to knit design device, otherwise, about knit design device record also former state be applicable to knit design method.Which of generation that the generation of line and narrowing coil walk crosswise first carries out turning back, difference walked crosswise by preferably make to turn back line and narrowing coil, also walk crosswise with the identical coil of the dual-side of accessory and narrow, can not depart from from pin when narrowing with the tuck together that turns back.In addition, the quantity increasing accessory or the process that the base of accessory is shortened also can be carried out in accessory generating unit, also can carry out in other part.The quantity of accessory can be inputted by operator, also can distribute the value prestored.Accessory is such as contact pin, but is not limited thereto.In addition, knit design method of the present invention produces by the weave data of flat knitting machine braid or the method for knitting program, passes through the use that obtained weave data etc. is weave data etc. by the situation of flat knitting machine braid.

Detailed description of the invention
Below, the most preferred embodiment for carrying out an invention is represented.
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 4.6 is input parts, at least possesses the manual input parts such as mouse, keyboard, trace ball, stylus, in addition, also can possess the input part of automatic network, input part etc. from moveable magnetic disc.8 is efferents, is the efferent to network or the efferent to moveable magnetic disc.10 is displays, the braided fabric etc. of Display designing process, and 12 is color printers, and 14 is program internal memories, stores for making computer play the program of function as knit design device 2.
If from the position that input part 6 specifies the summit of the profile of braided fabric and its center and multiple contact pin to collect, specify the sheet number of contact pin further, then contact pin generating unit 16 generates multiple contact pin, braided fabric to be divided into the multiple contact pin be made up of triangle.In addition, in shawl etc., because aforesaid center is in the hole of collar hole etc., so, there is the situation that center itself does not weave.In this case, such as, contact pin is generated, to carry out bag pin (Japanese original text: volt order) along the surrounding in hole.Therefore, there is actual contact pin shape to become and will cut the situation of the trapezoidal shape carrying out bag pin near the summit of 3 dihedrals along hole.
The profile of braided fabric is not limited to circle, also can be polygon oval or as shown in Figure 14.In addition, the center that the summit of accessory is collected, when for circular braided fabric, can specify in the position departed from from the center of circle.When for oval, be not limited to intersection point or the focus of oval major axis and minor axis, such as, the suitable position of being specified on the major axis of ellipse by operator becomes aforesaid center.Center in the present invention is not the center of the shape of figure relative to braided fabric, and refers to the position that the summit of multiple contact pin is collected.
The shape of contact pin, when for oval braided fabric, departs from from isosceles triangle, even the braided fabric of circle, if make center remove from the center of circle, then also departs from from isosceles triangle.Contact pin generating unit 16 such as waits certain angle to mark multiple line radially 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 divided by these lines is the base of contact pin.When braided fabric exists major axis or diameter, preferably center being specified on these axles, preferably braided fabric is divided into 2 along these axles, being divided into multiple contact pin respectively by being divided into the braided fabric of 2.At braided fabric relative in these axisymmetric situations, if contact pin is configured axisymmetrically relative to these, then only to being divided into a side of 2 braided fabrics to process.In addition, if braided fabric is divided into 2 along major axis, then major axis doubles as the side into contact pin.
The length on the base of contact pin is converted into the number of turns that direction walked crosswise by coil by contact pin evaluation section 18, the altitude conversion of contact pin is become the number of turns in wale direction.And, evaluate during the side of braiding contact pin, the number of turns on the base of contact pin of can narrowing.Have for narrowing and walk crosswise the preferred conditions such as 2 circles of narrowing in the left and right of contact pin by every 4 coils, contact pin evaluation section 18 evaluates whether meet this condition.The number of turns in wale direction is the quantity of the coil along wale direction of base to summit from contact pin.When being evaluated as the condition not meeting narrowing 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 whether meeting narrowing by contact pin evaluation section 18.
The handling part 20 that the turns back line line of braiding (carry out turn back) that makes to turn back is walked crosswise direction along coil and is not limited in 1 contact pin, but walks crosswise direction with coil and produce in braided fabric abreast.If because contact pin is not isosceles triangle, then the number of turns of two lateral plates is inconsistent, so, by the braiding of turning back 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 contact pin be woven.In addition, 1 line turned back is equivalent to the braiding that 2 coils are walked crosswise, and braiding of turning back is called merely turns back.The line that turns back is that maximum lateral plate pulls out towards minimum lateral plate from the number of turns in the wale direction multiple contact pin, and the great majority of the line that turns back turn back after by multiple contact pin.As the braiding of reality, 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 produces roughly equably along the wale direction of braided fabric.In addition, in this manual, to produce roughly equably or configuration narrowing coil is walked crosswise and the line that turns back is configured to feel the meaning uneven in appearance.The quantity that the number of turns in wale direction is not folded back line divides exactly, and in addition, situation about also not divided exactly by the quantity that narrowing coil is walked crosswise is a lot.Therefore, be difficult to fully configure equably.
Narrowing handling part specifies narrowing coil to walk crosswise (coil carrying out narrowing is walked crosswise) relative to each contact pin.In addition, the position that narrowing coil is walked crosswise also can be different in adjacent contact pin, and this point is different from the line that turns back.In addition, preferably narrowing coil is walked crosswise and is configured in contact pin roughly even along wale direction, and avoids the line that turns back.2 circle narrowings of each 2 circles walked crosswise by narrowing such as every 4 coils in the preferred left and right in contact pin.Such as, the number of turns on the base of leg-of-mutton contact pin is 80 circles, is highly 20 circles, is cut away at the top of contact pin and does in echelon, and on the top (trapezoidal top) of contact pin, walking crosswise direction at coil has 4 circles.And the height from the base of contact pin to top is 19 circles (being 20 circles to summit).If walk crosswise period at braiding 19 coil, narrowing 76 circle, then become to walk crosswise at whole coil and narrow, be difficult to weave.
Because each 2 circles in left and right are aggregated in 1 coil and walk crosswise the narrowing carrying out 4 circles, turned back by 1 time, weave 2 coils and walk crosswise, so, preferably when generating contact pin, by the position of the dual-side of contact pin generating unit correction contact pin, to make the difference of the number of turns of dual-side be even number, the number of turns on base is the multiple of 4.
Other handling part 24 carries out processing with relevant other of braiding, such as, and the process taken up one's knitting; Adding of bag pin, texture pattern, intarsia designs etc. when braiding to terminate etc. to need bag pin; When braided fabric be body sheet, have sleeve two sleeve designs etc.The design data of braided fabric, after the design of braided fabric completes, is converted to the weave data that can be performed by flat knitting machine by data conversion unit 26.
With reference to Fig. 1 ~ Fig. 9, especially Fig. 2, the design of braided fabric is described.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, and the center collected on the summit of contact pin is such as input on the major axis of braided fabric, the quantity (step 2) of input contact pin.Fig. 3, Fig. 4 represent contact pin 32 ~ 39 relative to 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 figure 3, centered by the C of position, in the diagram, centered by the C ' of position.Contact pin 32 ~ 35 and contact pin 36 ~ 39 are symmetrical, contact pin 42 ~ 45 and contact pin 46 ~ 49 also symmetrical.If changed from C to C ' at center, then the change in shape of contact pin, center is removed larger from the mid point of major axis, and the shape of contact pin is more uneven, and contact pin departs from from isosceles triangle.In addition, also can as the C of Fig. 4 ", center is departed from from the major axis A-A of braided fabric.In addition, the dotted arrow of Fig. 3, Fig. 4 represents the direction of braiding (wale direction), and the periphery of the profile 30 of braided fabric is braiding top.In an embodiment, what represent relative to major axis A-A symmetry is tubular knitted, but also can not carry out tubular knitted, and it is lower to first-class knitting and forming to carry out such as from Fig. 3, Fig. 4.
If the profile of braided fabric is determined, the position at center and the sheet number of contact pin are determined, then generate contact pin by contact pin generating unit 16.Such as, make the drift angle of contact pin publicly by the inside division of profile 30, make 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 that operator inputs close direction (make contact pin near so that the direction collected, the summit of each contact pin) (step 3).In addition, when not inputting the sheet number of contact pin, also can using the sheet number of the standard values such as 8 ~ 12 as contact pin.In addition, when not inputting close direction, also can according to make near in the summation of distance of barring-on the condition such as to diminish, automatically generate close direction.
Contact pin evaluation section 18 is evaluated whether one side and is met the condition of narrowing, and one side makes the coil on the base of contact pin narrow center (step 4).The (step 5) when not meeting the condition of narrowing, changes the border of contact pin, to increase the base of the contact pin of the quantity of contact pin or the condition of the satisfied narrowing of shortening.If increase the quantity of contact pin, then the periphery of the curve such as circle, ellipse can be more correctly made to be similar to, but, need the narrowing etc. making to become each 1 circle in the narrowing of each 2 circles of the both sides of contact pin, there is the situation that braid efficiency is low.
Fig. 5 a) in, by operator, center C is specified on the major axis A-A of the profile 50 of braided fabric, at Fig. 5 b) in generate multiple contact pin.Contact pin be generated as and make drift angle be α/2 in the contact pin 51,55 contacted with major axis A-A, make drift angle be α in other contact pin 52 ~ 54, contact pin 51 ' ~ 55 ' is symmetrical for major axis A-A with contact pin 51 ~ 55.Represent the height of contact pin with h, represent the length on base with d.At Fig. 5 c) in, if specify close direction, such as, be designated as the position of close center b, then move to this position near the summit being designated as each contact pin, Fig. 5 c) in arrow be close direction.When not inputting close center b, being the condition such as minimum according to the summation of the distance making the summit of contact pin close, specifying close center b by contact pin generating unit 16.In addition, close center b is the point being used to specify the direction making contact pin close, how to specify close center b to have impact to the easy degree of braiding.And no matter where specified in by close center b, if depart from from flat knitting machine, then the center C that the summit that braided fabric is also deformed into contact pin specifies in the step 2 at Fig. 2 collects.
When all contact pin meets the condition of narrowing, as Fig. 6 a) shown in, configure the line that turns back roughly equably along wale direction.Line 60 in the circle of the upper right quarter of figure is the lines that turn back, such as, from the right-hand member of contact pin 53 towards contact pin 54 side.The quantity of the line that turns back turned 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 in right median portion, the braiding formation walked crosswise by 2 coils of turning back, between the next wale turned back, is produced the difference of the number of turns of 2 circles, therefore, at the end position of line that turns back, such as, substitutes knitting, carry out the tuck (step 6) of 1 circle.
The coil carrying out narrowing is walked crosswise (narrowing coil walk crosswise) and be configured in each contact pin roughly equably 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).Because the coil having carried out tuck is walked crosswise be not suitable for barring-on, so, preferably make the coil having carried out tuck by turning back walk crosswise and walk crosswise eliminating from narrowing coil.Fig. 6 b) represent narrowing line (row along wale direction of narrowing circle) 62.If make each contact pin close along close direction on display 10, then become Fig. 6 c) like that, 64 be the periphery of profile play needlework.
To the shape of braided fabric additional stereoscopic, such as, to swell, as long as then increase the length (number of turns of wale) of wale compared with the design of the braided fabric of plane.In addition, when collar hole etc. is arranged on center, as long as along collar hole by each contact pin bag pin.Such example represents in the figure 7, by increasing the shape that coil carrys out additional stereoscopic along wale direction, arranges collar hole.
The top view of the shawl corresponding with the design of the contact pin of Fig. 7 is Fig. 8, Fig. 9 is side view.80 is shawls, and 82 is collar holes, and r is its radius, and 84,84 is precalculated positions of arm aperture, although be arranged by cutting etc. after braiding, also can be realized by knitting and forming.As described above, (step 8) of Fig. 2 in step 9, is converted to the weave data of flat knitting machine in other the process inputting after contact pin.Flat knitting machine has the needle-bar of more than 2, with the major axis of braided fabric profile for boundary, weaves a side by front needle-bar, weaves the opposing party by rear needle-bar.
Figure 10 ~ Figure 13 is the design representing carnival hat 90, and as shown in Figure 10, center C is in the position of 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, each contact pin (Figure 13) is appended to by implementing the region that hatched height h ' measures accordingly with protuberance.Later same with Fig. 2, the weave data of carnival hat 90 can be obtained.64 has been needlework.
Figure 14, Figure 15 represent the design of hexagonal braided fabric 100, and 101 ~ 106 is contact pin, have symmetrical contact pin 101 ' ~ 106 ' in the opposition side of major axis A-A.If design contact pin 101 ~ 105 in the same manner as Fig. 2, then become Figure 15 such, make contact pin 101 ~ 103 and contact pin 104 ~ 106 close as the arrow of figure.64 has been needlework.
Embodiment has feature below.
1) even if the braided fabric removed from the center of profile for braided fabric and the center of complex appearance, the braided fabric that can weave can also be designed.
2) if specify the profile of braided fabric and the center of position collected as the summit of contact pin, the sheet number of contact pin and close direction (becoming the position of close center b), then can roughly automatically generate multiple contact pin, evaluation could be narrowed.In addition, the sheet number of input contact pin and close direction can be omitted.
3) even if contact pin is not isosceles triangle, also can weave.
4) because avoid the narrowing of turning back on line, so, do not exist because of with narrowing barring-on together and make the situation that the tuck turning back line departs from.
5) to walk crosswise and turn back line, so the outward appearance of braided fabric is good because to configure narrowing coil substantially uniformly along wale direction.In addition, even if when arranging collar hole etc., the narrowing till using collar hole with keeping intact and turning back, there is no need to configure narrowing coil again and to walk crosswise and turn back line.
6) if center is specified on the major axis of braided fabric, if then to a side of major axis carry out contact pin generation, narrow, turn back, near etc., the design data obtained 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, also can be the braided fabric of the part had beyond the part and contact pin that are made up of contact pin.
