Abstract

The inventive method for knitting fabric and design device can capture a knitting yarn which is floating from a tip part and difficult to capture surely in the hook of a knitting needle. When a stitch loop is transferred to the knitting needle of a rear needle bed in order to increase the stitch loop formed by the knitting needle of a front needle bed, the knitting yarn is also fed to the hook of the knitting needle from a yarn carrier to form a new stitch loop. When the knitting needle is pulled in to the front needle bed side, the stitch loop remaining in the knitting needle raises a latch and displaces it to close the hook. Since the knitting yarn hanging down from the distal end of the feeder of the yarn carrier extends in the direction perpendicular to the paper surface and passes through the open/close range of the latch, the knitting yarn can be captured in the hook.

Coil is admitted the center upper portion that can be arranged on standing part 19 with transfer cam 16 with freeing in and out.It is symmetrical shapes that coil is admitted with transfer cam 16, in its two side ends, near the partial depth inclination of central authorities.
The upper barring-on of rise cam 12 admits dual-purpose transfer cam 17 roughly to form the triangle that the top is two chevrons side by side, in the pin heel of the knitting needle of the side directed barring-on side of upper limb, admits the pin heel of the knitting needle of side at lower edge side guiding barring-on.Admit the upper barring-on that is provided with of dual-purpose transfer cam 17 to guide triangle 21 at barring-on, connecting guide board triangle 22 in its both sides.
Under the situation of the knitting needle 3 that drives the barring-on side, shown in double dot dash line, the moving part 20 of rise cam 12 is become get the hang of, shown in solid line, make barring-on admit dual-purpose transfer cam 17 to become out state.On knitting needle 3,4, be provided with two and receive the pin heel of the driving that braid movement uses through cam system 10, upper needle heel 23 receives the effect of barring-on with three angular components 18, and bottom pin heel 24 receives the effect of coil formation with three angular components 15.If supposition has been loaded the cam carrier of cam system 10 under the situation that the left of scheming moves, the upper needle of the knitting needle 3 of barring-on side heel 23 is moved on the path shown in the double dot dash line with bottom pin heel 24.In addition, (a) that representes corresponding diagram 1 respectively with 23a, 23b, 23c, 24a, 24b, 24c be the upper needle heel 23 of (c) and the position of bottom pin heel 24 (b).And the position shown in the thread-carrier 6 is the position that the yarn feeding of stocking yarn 7 is received in the pinhock 3a of knitting needle 3 from the feed of thread-carrier 6.
Fig. 3 be to use Fig. 2 cam system 10, utilize widening shown in Figure 1 action, the knitting needle 4 of back needle-bar 2 carried out admitting as coil the state of the braid movement of side.The cam system 10 of Fig. 1 is loaded on the cam carrier of preceding needle-bar 1, and in Fig. 3, is loaded on the cam carrier of back needle-bar 2, therefore, for the ease of explanation, makes the tooth oral-lateral for down, representes symmetrically with Fig. 2.In Fig. 3, use identical reference marks with the part that Fig. 2 is corresponding, omit repeat specification.But admit at drive coil under the situation of knitting needle 4 of side, shown in double dot dash line, the moving part 20 of rise cam 12 formed get the hang of, shown in solid line, barring-on admits dual-purpose transfer cam 17 to form the state that comes out.
And knitting needle 4 also receives the effect of compressing tablet 25,26,27, in Fig. 2, has omitted diagram.Shown in Figure 1 identical in cam system 10 and the Japanese special fair 2-10262 communique for example, knitting needle 4 is in three positions, at the position needle selection of the effect that receives compressing tablet 25,26,27.In addition, knitting needle 3,4 also with Japan special fair 2-10262 communique in shown in Figure 2 basic identical.
Can change the effect of compressing tablet 25,26,27 respectively and do not act on.Admit side to make knitting needle 4 do the time spent as coil, shown in double dot dash line, intermediate preforms 27 is not acted on.In case make compressing tablet 25,26 act on knitting needle 4, then the bottom pin heel 24 of knitting needle 4 does not receive the effect of the standing part 19 of rise cam 12, and the coil that receives central authorities is admitted the effect with transfer cam 17, rises to the tooth oral-lateral.In case knitting needle 4 rises, upper needle heel 23 and barring-on are admitted the lower edge butt of dual-purpose transfer cam 17, descend along the guide surface that is formed on lower edge.In case the triangular facet 13a butt on the inclined-plane of heel 24 of bottom pin and sitch cam 13 then is directed, descends along triangular facet 13a.In addition, (a) that representes corresponding diagram 1 respectively with 23a, 23b, 23c, 24a, 24b, 24c be the upper needle heel 23 of (c) and the position of bottom pin heel 24 (b).
Fig. 4 be to use Fig. 2 cam system 10, make knitting needle 3 carry out the state of the braid movement of knitted fabric.On knitted fabric, make the front end of knitting needle 3 temporarily get into tooth mouth 5, up to coil arc 8 from latch needles 3b retreat move back the circle position.Because knitted fabric 9 is afterburning by the below to tooth mouth 5, therefore, the coil arc 8 that is connected with knitted fabric 9 rests near the front end of preceding needle-bar 1.Fig. 4 (a) is a needle-bar 1 before the knitting needle 3 in moving back circle position entering tooth mouth 5 is withdrawn into, and admits the state of the yarn feeding of stocking yarns 7 from thread-carrier 6.Shown in Fig. 4 (b), if knitting needle 3 is drawn in preceding needle-bar 1, retreated from tooth mouth 5, then coil arc 8 begins to close latch needles 3b.Shown in Fig. 4 (c), latch needles 3b closes pinhock 3a, if up to the front end of coil arc 8 disengaging knitting needles 3, from the position height of the sagging stocking yarn 7 of the feed of thread-carrier 6 lower ends, then can't stocking yarn 7 be captured in the pinhock 3a and sting yarn.Like the explanation of in patent documentation 4, Fig. 2 being carried out, in the long not back between knitting zone, the height of stocking yarn 7 increases, and the braid movement of knitted fabric is difficult to sting yarn.
Fig. 5 is the transition status that carries out the cam system 10 under the situation of braid movement of knitted fabric of Fig. 4.Braid movement at knitted fabric drives under the situation of knitting needle 3, shown in solid line, makes the moving part 20 of rise cam 12 be the state that comes out, and shown in double dot dash line, makes barring-on admit dual-purpose transfer cam 17 for getting the hang of.In addition, even under the state of Fig. 2, make knitting needle 3 carry out the braid movement that barring-on is used, if the coil that relative knitting needle 4 is carried out under Fig. 3 state is admitted the braid movement of usefulness, knitting needle 3 also forms the coil arc identical with knitted fabric.In addition, in addition, (a) that representes corresponding diagram 4 respectively with 23a, 23b, 23c, 24a, 24b, 24c be the upper needle heel 23 of (c) and the position of bottom pin heel 24 (b).And the position shown in the thread-carrier 6 is the position of admitting the yarn feeding of stocking yarn 7 from the feed of thread-carrier 6 to the pinhock 3a of knitting needle 3.
Fig. 6 is the simplification example of knitted fabric 9.At the area of the pattern 9xa of the interval braiding of the X of wale direction A,, in the area of the pattern 9ya of A, in each row, weave the area of the pattern 9yb of B respectively in the Y interval of wale direction.And,, only weave the area of the pattern 9za of A in the Z interval of wale direction.On such knitted fabric 9, the ledger line of the end 28 of area of the pattern 9yb or from the end 29 subtract line etc. the time, need carry out the processing of connecting line.
Fig. 7 representes that the summary of the straight-bar machines 30 of making knit fabric 9 constitutes.On preceding needle-bar 1, be provided be mounted with can weave, the cam carrier 31 of the cam system of barring-on, widening etc.Cam carrier 31 selectively drives thread-carrier 6a, the 6b that can move along the thread-carrier track 32 that is erected at tooth mouth top, vertically moving back and forth of needle-bar.The area of the pattern of the A of Fig. 6 is by the stocking yarn 7a braiding of supplying with from thread-carrier 6a, and the area of the pattern of B is by the stocking yarn 7b braiding of supplying with from thread-carrier 6b.On straight-bar machines 30, from upright tapered bobbin 33a on the bobbin cradle 33, the 33b of being located at through top spring (day ば ね) device 34 or yarn feeding device 35, supply with stocking yarn 7a, 7b to each thread-carrier 6a, 6b with the tension force of almost fixed.When taking up one's knitting knitted fabric 9, the end of clamping stocking yarn with the anchor clamps 36 of end that are arranged on needle-bar.Under the situation of the knitted fabric 9 of weave diagram 6, even the X of the wale direction that takes up one's knitting is interval, clamp the end of stocking yarn 7b with anchor clamps 36, up to the end 28 of the interval area of the pattern 9yb of Y that takes up one's knitting always.Therefore, when taking up one's knitting end 28, the position of the stocking yarn of supplying with from thread-carrier 6b 7 is the high positions of floating from tooth mouth 5.Therefore,, utilize, then can be more positively the stocking yarn 7 of high position be captured in the pinhock 3a if be conceived to the braid movement of widening shown in Figure 1 though the braid movement of knitted fabric shown in Figure 4 is difficult to stocking yarn 7 is captured in the pinhock 3a.
In addition; Need the stocking yarn 7 of high position be captured and be not only in the pinhock 3a in braiding during intarsia designs, during the flotation line braiding that after knitting needle is not woven continuously, weaves or in knitted fabric, restart to weave independently also needs during knitted fabric regional such as pocket.If also utilize widening in this case, then can really stocking yarn 7 be captured in the pinhock 3a.
Fig. 8, Fig. 9 and Figure 10 are the knitted fabric 9 about Fig. 6, the state that behind the X interval of wale direction that is through with, carries out the braiding in Y, Z interval.The relative row number of numeral that shows as row in the left side of each figure.In the row of odd number, cam carrier is moved to the left, in the row of even number, cam carrier is moved right.The mark of representing as system on the right side of each figure is Fig. 2, the cam system 10 shown in 3 and 5 to be loaded on each cam carrier 31 under three the situation, and which expression uses.S1 representes that system, the S2 of side represent that middle system, S3 represent the system of back row side in advance.Therefore, when cam carrier was moved to the left, the cam system 10 in left side was S1, and the cam system 10 on right side is S3, and when moving right, the cam system 10 on right side is S1, and the cam system 10 in left side is S3.In addition, the use of cam system is an example.And, as shown in Figure 9, owing to repeat the pattern of row 7 and row 8, repeated multiple times, therefore, row 9 later numerals are not to be the meaning of benchmark, the 9th later row with row 1.
On row 1, use thread-carrier 6a and the S1 of system shown in a, at preceding needle-bar 1, utilize the last row in the X interval of stocking yarn 7a woven stitch stringer direction.Using system S2 simultaneously, needle-bar 1 needle-bar 2 barring-ons backward in the past in the area of the pattern of A.The purpose of this barring-on is in tooth mouth 5, to form the part of intersecting with stocking yarn 7a.The position that forms cross section is preferably near the end of braiding amplitude of knitted fabric 9.If in the area of the pattern of A, utilize ribbed knitting etc. to form cross section, or with knitted fabric 9 braiding pouches, the end exist connect before needle-bar 1 and after the stocking yarn of needle-bar 2, then do not need to form in addition cross section.
From the take up one's knitting interval initial row of Y of wale direction of row 2.As shown in Figure 7, supply with the left standby of the thread-carrier 6b of stocking yarn 7b at preceding needle-bar 1.Under the situation of the X having woven the wale direction is interval, also weave B in the X interval area of the pattern, stocking yarn 7b from the feed of the lower end of thread-carrier 6b not with anchor clamps 36 but be connected with the end of area of the pattern of B after the braiding.Under this state, if using system S3, will be as the thread-carrier 6b shown in the b to right-hand drive, then stocking yarn 7b hangs on the cross section that forms on the row 1 back to 28 yarn feedings of the end of Fig. 6.The widening braiding is carried out in end 28.As stated, owing to utilize widening, therefore,, also can capture really in the pinhock 3a of knitting needle 3 even the position of the stocking yarn 7b that supplies with from thread-carrier 6 is high.
In addition, if the formation or the specification of thread-carrier 6 and cam system 10 are different, then cam carrier 31 is difficult to one side and drives thread-carrier 6b and simultaneously carry out widening sometimes.In this case, utilize moving right of cam carrier 31, stop after making thread-carrier 6b move to the area of the pattern 9yb of B earlier.End 28 at area of the pattern 9yb; Though the position of the stocking yarn 7b that supplies with from thread-carrier 6b is high; But separately the woven stitch line gets final product, that is, put down thread-carrier 6b, with the row of sky cam carrier 31 be moved to the left; Cam carrier 31 is moved right, utilize widening that stocking yarn 7b is captured on the pinhock 3a.
In row 3; Thread-carrier 6b is moved to the left; Using system S1 forms with the coil of following with the coil arc of knitting needle 4 widening of back needle-bar 2 and carries out adding pin to the knitting needle 4 of the area of the pattern 9ya of the A of adjacency in the end 28 that row 2 has been carried out widening.The widening, the coil arc after widening on the knitting needle 4 of back needle-bar 2 that are utilized in row 2 carry out knocking over, become old circle arc.
In row 4, the system that utilizes S1 is to right-hand drive thread-carrier 6b, the system that utilizes S2 backward needle-bar 2 add pin needle-bar 1 barring-on forward.For adding pin, to the stretch barring-on of stocking yarn 7b and the S2 of system of opposite direction, can form the strand coiling in the end of the area of the pattern side of the A of preceding needle-bar 1 through the S1 of system.
In row 5, the system S1 of utilization makes thread-carrier 6b get into the area of the pattern side of A, carries out the barring-on on the knitting needle 3 of needle-bar 1 before the coil of knitting needle 4 barring-ons of needle-bar 2 turns back to backward in row 1 again.In order to form cross part, under the situation of carrying out widening, remove, discharge the coil arc on the knitting needle 4 that is formed on back needle-bar 2.Therefore this cross section, no longer needs after row 2 finishes because the starting point during as ledger line plays a role.
In row 6, to adding after the pin of the end of the area of the pattern of the A of adjacency, system S1 drives the row that thread-carrier 6b weaves the area of the pattern of B.And system S2 drives the area of the pattern of thread-carrier 6a braiding A.And using system S3, will remain on coil arc knitting needle 3 barring-ons of needle-bar 1 forward on the knitting needle 4 of back needle-bar 2 in row 2 widening, in the end 28 of the area of the pattern of B
6 yarn treatment, can prevent to decoherence to end 28 from row 2 to row.In widening, utilize the coil arc after the widening to carry out though this prevents to decoherence, prevent that the method for decoherencing from being example, also can use the method beyond this method.
If do not prevent to decoherence, also can remove the coil arc after the widening.If only remove the coil arc after the widening, its result forms and the general same coil arc of knitted fabric, can under the high situation in yarn feeding positions such as ledger line or flotation line braiding, use.And, also can be behind ledger line, in same woven stitch line, after forming the coil arc on the knitting needle different, remove the coil arc after the widening with the knitting needle that is used for widening.
And, temporarily, carry out widening with coil arc barring-on, in case will utilize the new coil arc that forms of widening to remove, its result turns back to the preceding state of barring-on.For example; When the ledger line of the area of the pattern of the B that takes up one's knitting, the coil arc of the end of the area of the pattern of A is carried out barring-on, carries out widening, in woven stitch line identical or follow-up woven stitch line with widening; After the area of the pattern of B forms the coil arc; In case remove in the end of the area of the pattern of A and to utilize the new coil arc that forms of widening, then the coil arc of the area of the pattern of A returns the state before the barring-on, can weave the ledger line of the area of the pattern of B really.
On row 7 and row 8, utilize the S1 of system, S2 simultaneously to drive thread-carrier 6a, 6b one side the row braiding A of necessary amount and the area of the pattern of B repeatedly.
On row 9, cam carrier is moved to the left, weave at the area of the pattern of identical row conversion A and the area of the pattern of B, weave last row.Utilize the S3 of system with the coil arc of the end 29 of the area of the pattern of B knitting needle 3 knitting needle 4 barring-ons of needle-bar 2 backward of needle-bar 1 in the past at last.
On row 10, utilize the S1 of system that thread-carrier 6b is returned to the area of the pattern drive of B.
On row 11, utilize the S1 of system one side that thread-carrier 6b is driven to the area of the pattern side of A, one side in the area of the pattern of B, carried out from the end for 29 adding pin and forming coils to the knitting needle 3 of second preceding needle-bar 1 to the knitting needle 4 of the back needle-bar 2 of end 29.
On row 12, utilize the S1 of system, will be formed on coil arc knitting needle 3 barring-ons of needle-bar 1 forward on the knitting needle 4 of back needle-bar 2 in the end 29 of the area of the pattern of B.It is capable of using that 12 yarn treatment prevents to decoherence in the end that subtracts line 29 from row 9 to row.This prevents to decoherence also is example, is not limited to this method certainly.
On row 13, using system S1, near the knitting needle 3 that the end of the braiding amplitude of the area of the pattern of A, carries out needle-bar 1 in the past is the barring-on of the knitting needle 4 of needle-bar 2 backward.
On row 14, make thread-carrier 6b return the area of the pattern of B.
On row 15; One side make thread-carrier 6b beyond the braiding amplitude of knitted fabric 9, move with than the coil position behind barring-on on the row 13 more away from the area of the pattern of B, one side makes the coil arc behind barring-on on the row 13 be sidelong pin at the knitting needle 3 of preceding needle-bar 1.Like this, can be really the end 29 from the area of the pattern of B be subtracted connecting line that line produces and capture near the braiding end of knitted fabric 9, prevent to float at tooth mouth 5.
On row 16, thread-carrier 6b is returned than the position of the knitting needle after the widening 3,4 more near the position of the area of the pattern side of B.
On row 17, utilize the S1 of system to drive thread-carrier 6b, add pin in the outside of the braiding amplitude of knitted fabric 9.Owing to utilize the widening of row 15, really connecting line is captured knitting needle 4, therefore, also can add pin really.System S2 will utilize the knitting needle 4 of the new coil arc that forms of the widening on the row 15 needle-bar 2 from the back to remove.The coil arc that removes is used as the stocking yarn that subtracts line that adds pin in the outside of knitted fabric 9 and absorbs.And; The coil arc of old coil arc that becomes the coil arc of new formation is by the coil arc of barring-on on row 13; The widening that the part of this coil arc is utilized on the row 15 hangs over preceding needle-bar 1 side, therefore, is absorbed by the coil arc of the knitting needle 3 of preceding needle-bar 1; Its result, the barring-on on row 13 returns the original place in row 17.
On row 18,19, weave the area of the pattern of A repeatedly to the Z interval of wale direction, with the row of requirement.Required row is to the last will be formed on the outside pin that adds in row 20 to remove, and the connecting line that subtracts line can not left behind from tooth mouth 5 with knitted fabric 9 yet, floats from tooth mouth 5.
In addition, after row 15 is carried out widening, after the row of braiding requirement,,, also can not carry out the processing on the row 20 in case add pin in row 17 formation if the knitting needle 4 of coil arc needle-bar 2 from the back is removed.
Figure 11 is illustrated in the effect that forms cross section on the row 1 of Fig. 8.Figure 11 (a) is illustrated in cam carrier 31 on the row 1 drives state from thread-carrier 6a to left.Supply with the outside standby of the thread-carrier 6b of stocking yarn 6b in the braiding amplitude of knitted fabric 9.Under the situation of the area of the pattern that in advance weaves B on the knitted fabric 9, stocking yarn 7b becomes connecting line from the feed of the lower end of thread-carrier 6b.
After Figure 11 (b) was illustrated in and forms the formed cross section of barring-on on the row 1 of Fig. 8, cam carrier was to the state of right-hand drive thread-carrier 6b on row 2.For the end 28 of weave diagram 6, be that starting point 40 is supplied with the stocking yarn 7b that becomes connecting line with the cross section.Under the situation that starting point 40 is not set, when braiding end 28, direct supply company wiring is played in the end of the area of the pattern of the B of before braiding.The position of the area of the pattern of the B of braiding for example is the zone of knitted fabrics 9 such as 9b1,9b2 earlier, can carry out various variations as required, and therefore, the braiding condition of carrying out the end 28 of ledger line also changes.If starting point 40 is set, though from area of the pattern 9b1,9b2 to the connecting line 7b1 of starting point 40, the change in location of 7b2, also can make from the position relation of starting point 40 connecting line 7b0 of 28 stablely to the end, the braiding condition is fixed.
Figure 12 and Figure 13 are the expression summary order of the consideration method that widening catches connecting line and the summary formations of the design apparatus that generates the weave data that comprises this order utilized discussed above.Shown in figure 12, under the situation of utilizing straight-bar machines shown in Figure 7 30 braidings knitted fabric 9 shown in Figure 6, at step s1 input pattern data.Judge whether that at step s2 stocking yarn 7b becomes the interval of connecting line.When judgement has connecting line, utilize widening to catch connecting line at step s3.In step s2, judge when not having connecting line, carry out the braiding of common knitted fabric etc.
Shown in figure 13, design apparatus 50 is the software that designs knitted fabric to be installed on the general calculation machine 51 form.Can install or recording medium is installed on the external record device 55 through the download of communicator 54 and install.Comprise in this software generation with order shown in Figure 12, utilize widening to catch the program of the weave data of connecting line.Display unit such as input units such as keyboard, digital quantizer, mouse 52, graphic alphanumeric display 53, can be connected with computer 51 with external record device 55 of the communicator 54 of PERCOM peripheral communication, dismantled and assembled various recording mediums etc. through LAN etc.The operator is to input unit 52 input design datas, and one side is checked the design result that on display unit 53, shows, one side is carried out the design of knitted fabric 9.If the operator judges that the interval that forms connecting line is long, the pinhock 3a, the 4a that in the braid movement of common knitted fabric etc., are difficult to capture knitting needle 3,4 are last, then indicate widening.According to this indication, computer 51 appends the weave data of widening.The weave data that has appended widening is transported to straight-bar machines 30 through communicator 54, record on the recording mediums such as CD or USB from external record device 50 after, the input straight-bar machines 30, carry out the braiding of knitted fabric 9.
