Description
Technical field
The present invention relates to supply with stocking yarn and the straight-bar machines of making knit fabric and give the yarn method to the knitting needle that carries out braid movement.
Background technology
All the time, on straight-bar machines, select to drive the knitting needle of on needle-bar, arranging setting, making knit fabric by being loaded into along the triangle on the cam carrier of needle-bar walking.On the straight-bar machines of V bed type, a pair of needle-bar is with before and after being configured in across the relative mode of tooth mouth.The tooth mouth extends upward at the right and left of straight-bar machines, and each needle-bar is higher with the tooth oral-lateral, along with the mode away from tooth mouth step-down tilts.The knitting needle that is selectively driven on each needle-bar is accepted the supply of stocking yarn and is formed coil from tooth mouth top with respect to tooth mouth advance and retreat.The stocking yarn of supplying with to knitting needle, the yarn-feeding port that possesses from the thread-carrier along the yarn feeder of the guide rail walking of setting up above the tooth mouth etc. supplies to knitting needle.A plurality of thread-carriers are set,, can switch stocking yarn and making knit fabric thus by cam carrier interlock optionally.
Fig. 3 represents to be loaded into the example of configuration of the triangle of cam carrier.On the base plate 1 of cam carrier, for example be mounted with two groups of cam systems 2,3 in the left and right sides of center line 1a.Each is organized cam system 2,3 and comprises and drive needle selecting cam 2b, the 3b that knitting cam 2a, 3a that knitting needle uses and needle selection are used to have the identical formation in the left and right sides.Be loaded into the quantity of the cam system of cam carrier, existing one group situation also has three groups of above situations.Existing each group of many group cam systems is the situation of identical formation, also promising different situations about constituting.The knitting needle that cam system 2,3 by this formation drives is a latch needles, at the front end with respect to tooth mouth advance and retreat pinhock is set, and opens and closes by needle latch, at tail end-side the pin heel that needle selection is used is set.The pin heel of the driving usefulness of knitting cam 2a, 3a effect is set between the front end of knitting needle and tail end.
Knitting cam 2a, 2b guide the driving of knitting needle to call in person with pin along pin heel path 4.On needle-bar, form on the left and right directions at Fig. 3 at the suitable up and down upwardly extending needle tray in side and to arrange with certain needle gage with Fig. 3.Each knitting needle is housed in respectively in the needle tray, in needle tray along the bearing of trend of needle tray and slide displacement.Pin heel path 4 is at the upper limb of rise cam 5 and draw between the lower edge of pin triangle 6 and form.Both sides at pin heel path 4 dispose the sitch cam 7,8 that is also referred to as stitch cam.
For example, the imaginary cam carrier situation of walking to the right-hand mobile mode shown in the arrow 1R with base plate 1.When the guiding of knitting needle by pin heel path 4 arrived hook yarn position 4a, stocking yarn supplied to the pinhock of knitting needle from the yarn-feeding port 9 of the thread-carrier of going ahead of the rest with amount of travel X0 with respect to hook yarn position 4a.The driving of the knitting needle that is directed along pin heel path 4 after transferring to the interval 4c of shoulder of level, begins to descend at hook yarn position 4a through the interval 4b of the chevron of central authorities with the pin heel once more.Be positioned at and compare keep left side and accepted knitting needle to yarn of hook yarn position 4a, it drives with the pin heel and is left behind along the inclined-plane of sitch cam 8.When this was left behind, stocking yarn was captured in pinhock, the knitting needle fastening in the old coil of shank side by knocking over.When knocking over, pinhock is closed by needle latch.Exist by back row side and accept earlier to give yarn and form under the situation of knitting needle of coil comparing hook yarn position 4a, on the pinhock of the knitting needle of hook yarn position 4a, be captured to the stocking yarn that the yarn-feeding port 9 of side in advance extends from the stocking yarn of being caught by the pinhock of the knitting needle of back row side.Under the situation of the knitting needle of not giving yarn than the knitting needle acceptance earlier of hook yarn position 4a, the knitting needle of hook yarn position 4a becomes the braiding end of approaching side, and the old coil of the shank side of itself is caught by pinhock to the stocking yarn that yarn-feeding port 9 extends from fastening in this knitting needle.
The thread-carrier fastening is in the linkage pin that haunts from cam carrier and interlock.The yarn-feeding port 9 of the thread-carrier in the cam carrier interlock is still in to yarn position 9a relatively with respect to the cam system of cam carrier.Compare hook yarn position 4a for yarn position 9a and become side in advance with amount of travel X0.
In the control of haunting of the linkage pin of cam carrier, under the situation about using, worry that each yarn-feeding port 9 takies near the same space the tooth mouth and interferes switching a plurality of thread-carriers.After making the preceding employed thread-carrier of switching keep out of the way the outside of knitting width, make and switch the employed thread-carrier interlock in back, then can avoid interfering, but the travel distance of cam carrier is elongated.In addition, as the knitted fabric of intarsia pattern, elaborate pattern, make a plurality of thread-carriers stay in the knitting width and under the reusable situation, thread-carrier is kept out of the way outside the knitting width by the boundary vicinity that finishes from the interval of the stocking yarn braiding of each thread-carrier.In order to make a plurality of thread-carriers stay in the knitting width and can switch, need make yarn-feeding port 9 can move up and down from the direction that thread-carrier lets droop (for example with reference to patent documentation 1).In addition, also can use yarn-feeding port 9 swing displacements and switching to yarn and the thread-carrier (for example with reference to patent documentation 2) kept out of the way.
Do not move if do not make thread-carrier and cam carrier interlock, but can then wait in expectation and to omit the walking of the needed cam carrier of switching that only is thread-carrier voluntarily, boost productivity.Also disclose the full-jacquard mechanism of following straight-bar machines: in the walking of a stroke of cam carrier, switch a plurality of self-propelled thread-carriers and use, and weave (for example with reference to patent documentations 3) such as intarsia patterns simultaneously.In the 4th hurdle of patent documentation 3 the 5th row～the 16 row, record following item: the part that is equivalent to yarn-feeding port 9 " slides up and down freely ", " be applied in elasticity upwards all the time, move up and down a little where necessary " by " helical spring " according to decorative pattern.With reference to accompanying drawing 8 of patent documentation 3 etc., this record may be interpreted as: by spring energized will be in the braiding in a plurality of intervals of intarsia pattern employed yarn-feeding port remain on the higher position and interfere avoiding, only in the braiding in each interval employed yarn-feeding port by moving up and down step-down.

Summary of the invention
For the height of yarn-feeding port 9 on the tooth mouth of thread-carrier, if even if also lower above knitting needle, then the vibration of stocking yarn is also less, thereby preferred, and described thread-carrier is supplied with the stocking yarn of the pinhock hook yarn that is used to make knitting needle.But worry yarn-feeding port 9 each other interference and the stocking yarn of yarn-feeding port 9 extensions that braiding is stopped during from braidings such as intarsia pattern or elaborate patterns the employed knitting needle problem of hook yarn mistakenly.The up-down mechanism of patent documentation 1 and patent documentation 2 described yarn-feeding ports 9 is provided with in order to prevent this problem.
But when the up-down mechanism of yarn-feeding port 9 was set, the formation of thread-carrier was complicated, has increased manufacturing cost.In addition, in the thread-carrier of patent documentation 3 described self-propelleds, possess the increase of the weight that up-down mechanism causes, the result also makes the load that drives walking increase.
Even the purpose of this invention is to provide the straight-bar machines of giving yarn that yarn-feeding port is moved up and down also can suit and give the yarn method.
The invention provides a kind of straight-bar machines, it is provided with a plurality of tracks above the tooth oral-lateral of the needle-bar that is disposed with knitting needle, the thread-carrier that possesses yarn-feeding port on each track voluntarily, give yarn and making knit fabric from yarn-feeding port to knitting needle, described knitting needle by along the driving of the cam carrier of needle-bar walking and successively with respect to tooth mouth advance and retreat to carry out braid movement, this straight-bar machines is characterised in that
Even the height that the height setting of the yarn-feeding port of thread-carrier is intersected, also can not interfere with the knitting needle that enters the tooth mouth in braiding for the yarn-feeding port of co-orbital thread-carrier not,
Comprise control device, this control device is in the speed of travel of a row inner control thread-carrier of braiding, carry out following adjustment: make thread-carrier with respect to the amount of travel of acceptance to the position of the knitting needle of yarn, with with respect to knitting width enter the knitting needle of side the time compare the time greatlyyer with respect to the knitting needle in the knitting width except this knitting needle, and make the height of the stocking yarn condition during according to braiding of giving yarn to knitting needle from yarn-feeding port form suitable hook yarn height.
In addition, among the present invention, it is characterized in that described control device is adjusted into the amount of travel of described thread-carrier on the continuous interval of the knitting needle of not giving yarn in described knitting width and becomes big.
In addition, among the present invention, it is characterized in that described control device is adjusted described amount of travel by changing described thread-carrier with respect to the speed of described cam carrier.
Further, what the invention provides a kind of straight-bar machines gives the yarn method, it is characterized in that,
The knitting needle that carries out braid movement with respect to tooth mouth advance and retreat from needle-bar is shifted to a side of needle-bar successively, and supplies with stocking yarn and during making knit fabric from the yarn-feeding port of tooth mouth top,
Adjust the amount of travel that yarn-feeding port is gone ahead of the rest to a side of this needle-bar with respect to this knitting needle, so that accept to give the hook yarn height on the knitting needle of yarn to become suitable according to the braiding condition.
According to the present invention, even with the height setting of the thread-carrier of self-propelled for the yarn-feeding port of co-orbital thread-carrier not intersect also not can with braiding in enter the height that the knitting needle of tooth mouth is interfered, therefore, even under the situation of using a plurality of thread-carriers, also can avoid interference with knitting needle.Because yarn-feeding port is higher, therefore can also make problem that the knitting needle that uses the stocking yarn that extends from the yarn-feeding port that stops woven hooks mistakenly etc. be difficult to take place.In addition, even, can not cause damage, can braiding not caused obstacle because of yarn-feeding port interference each other contacts yet.On the knitting needle of the braiding end of the approaching side of knitting width, the amount of travel of thread-carrier is less, therefore, even the yarn-feeding port of higher position is near knitting needle, draw stocking yarn with respect to pinhock at lower position from the old coil that is hooked in the shank side, also can make pinhock hook stocking yarn at the suitable height place midway of rising till the yarn-feeding port of higher position.With respect to other knitting needles in the knitting width, increase the amount of travel of thread-carrier, it is low therefore can to make pinhock hook the height of aspect ratio yarn-feeding port of stocking yarn, and what can suit gives yarn.Even on thread-carrier up-down mechanism is not set so that yarn-feeding port moves up and down, what also can suit gives yarn, therefore can reduce cost, and can also alleviate the load when driving walking.
In addition, according to the present invention, so that the amount of travel of thread-carrier adjusts the amount of travel of thread-carrier in knitting width the knitting needle of the yarn mode that continuous interval increases, therefore, for the knitting needle of giving yarn, can on the suitable height midway till the yarn-feeding port of higher position, make pinhock hook stocking yarn in rising.Owing to make the height of stocking yarn lower, therefore do not need to utilize obsolete knitting needle in the braiding, can realize the suitable yarn of giving by the amount of travel of adjusting thread-carrier.
In addition, according to the present invention, thereby owing to come the amount of travel of change speed adjustment thread-carrier according to the walking of the cam carrier that drives the knitting needle braiding, so can supply with stocking yarn aptly according to the braid movement of knitting needle.
And then, according to the present invention, adjust the amount of travel of yarn-feeding port with respect to knitting needle, so that accept to give the hook yarn height on the knitting needle of yarn to become suitable according to the braiding condition, therefore, even yarn-feeding port is moved up and down, what also can suit gives yarn.

The specific embodiment
Fig. 1 represents the basic ideas of giving the yarn method as the straight-bar machines of one embodiment of the present invention.(a) benchmark of the amount of travel of yarn-feeding port is set in expression with respect to the knitting needle midway of knitting width.(b) mode of expression to make hook yarn height become suitable according to the braiding condition adjusted the benchmark of yarn-feeding port with respect to the amount of travel of going ahead of the rest to the knitting needle of yarn object.
Shown in Fig. 1 (a), when being suitable for design of the present invention, even the aspect ratio of yarn-feeding port 10 as the suitable height height of the yarn-feeding port 9 of the benchmark of prior art, also can be to make the pinhock seizure stocking yarn 11 of knitting needle 12 near the state that is equal to prior art.For example in the conventional example of Fig. 3, will when giving yarn, the knitting needle of hook yarn position 4a realize that the situation of suitable hook yarn is as benchmark from the yarn-feeding port 9 of giving yarn position 9a of going ahead of the rest with amount of travel X0.Fig. 1 (a) has represented following situation: supply with stocking yarns 11 even exceed the yarn-feeding port 10 of the higher position of y from the benchmark than the yarn-feeding port 9 of prior art to knitting needle 12, if make the amount of travel X0 increase x of the amount of travel X2 of yarn-feeding port 10 than yarn-feeding port 9, then the inclination of stocking yarn 11 is also identical.Stocking yarn 11 is for example from extending until yarn-feeding port 9,10 for the pinhock of the knitting needle of yarn than knitting needle 12 acceptance earlier.But the best amount of travel that becomes suitable hook yarn height is according to the braiding condition relevant with knitting needle 12 and different.In addition, knitting needle 12 is not only the latch needles that is driven by triangle shown in Figure 3, and also can similarly be suitable for the present invention for for example No. 2946323 disclosed the sort of compound needle of Japan Patent.
Under the situation of using a plurality of yarn-feeding ports 10, dispose a plurality of tracks for yarn-feeding port 10 walkings.When the yarn-feeding port 10 of walking on different tracks can diverge to the intersection of advancing, even allow yarn-feeding port 10 contact each other of the degree of unlikely damage, the scope in the space that yarn-feeding port 10 passes through also can be widened at the tooth mouth, interferes with the knitting needle that enters the tooth mouth easily.The yarn-feeding port 9 of the aspect ratio prior art by making yarn-feeding port 10 exceeds the amount of y, yarn-feeding port 10 and the interference that enters the knitting needle of tooth mouth in the time of can avoiding by the tooth mouth etc.
Fig. 1 (b) represents following situation: knitting needle 12a, 12b, 12c, 12d, 12e, 12f ..., 12s braiding interval arranged side by side situation under, preferably according to each knitting needle 12a, 12b, 12c, 12d, 12e, 12f ..., the braiding condition on the 12s, make best amount of travel difference.Yarn-feeding port 10 knitting needle 12a, 12b, 12c, 12d, 12e, 12f ..., 12s the interval to right-hand move and under the situation of braiding, the knitting needle 12a of left end becomes approaching side.Thisly then weave to the woven stitch line of left to right-hand woven stitch line.Cam carrier as shown in the reference numeral 13, the counter-rotating direction of travel.When in right-hand braiding, making pinhock enter the tooth mouth, on the knitting needle 12a of left end, shift to shank from pinhock as old coil 14 at the coil that in the braiding of left, forms.
In order to become the coil that forms as new coil on the pinhock of the left end knitting needle 12a of the beginning of right-hand braiding, the stocking yarn 11a that begins to supply with from the yarn-feeding port 10 of giving yarn position 10a is drawn from the old coil 14 that shifts to shank.Because old coil 14 is hooked on the shank of knitting needle 12a, therefore the position of drawing stocking yarn 11a is lower than the position of the pinhock of knitting needle 12a.12a also is for knitting needle, and when the yarn-feeding port of going ahead of the rest with amount of travel X2 shown in Fig. 1 (a) 10 was supplied with stocking yarns 11, the position of drawing stocking yarn 11 was lower, so also step-down of the height of hook yarn.During the height step-down of hook yarn, worry that the shank side that hangs with old coil 14 to rising to the bait at knitting needle 12a gives yarn, be not caught in the pinhock and with old coil 14 by knocking over, or on latch needles, be hooked in the front end of needle latch and stocking yarn 11 cut off.Therefore, preferably,, will be set at forr a short time, supply with stocking yarn 11a in the higher position to the amount of travel X1 of yarn position 10a than the amount of travel X2 that gives yarn position 10d etc. with respect to the knitting needle 12d of centre with respect to the knitting needle 12a that enters side.On the knitting needle 12a of the braiding end of the approaching side of knitting width, give the amount of travel X1 of yarn position 10a less, even therefore the yarn-feeding port 10a of higher position is near knitting needle 12a, stocking yarn 11a is drawn on lower position with respect to pinhock from the old coil 14 that is hooked in the shank side, also can make pinhock hook stocking yarn 11a on the suitable height midway of the yarn-feeding port 10 of higher position in rising.
After the knitting needle 12a of approaching side, for knitting needle 12b, the 12c of continuous formation coil, 12d, 12e, 12f ... interval knitting needle 12d midway supplies with the stocking yarn of being caught for the pinhock of the knitting needle 12c of yarn by acceptance earlier to pinhock.Therefore, make yarn-feeding port 10 in advance in the mode of giving yarn position 10d that becomes the amount of travel X2 shown in Fig. 1 (a).From for the amount of travel X1 that gives yarn position 10a of the knitting needle 12a of braiding end to for knitting needle 12b, the 12c in continuous weaving interval, 12d, 12e, 12f ... the change of the amount of travel X2 that gives yarn position 10d etc., can yarn-feeding port 10 speed voluntarily be realized by change.But, for the knitting needle 12b adjacent with the knitting needle 12a of approaching side with amount of travel from X1 moment to be altered to X2 be difficult.Therefore, enter continuous formation coil knitting needle 12b, 12c, 12d, 12e, 12f ... when interval, by the continuous speed control of thread-carrier, amount of travel is changed to X2 from X1.
Continue untapped knitting needle 12e, 12f ... supply with under the situation of stocking yarn 11s to the pinhock of knitting needle 12s afterwards, make to the amount of travel X3 on the 10s of yarn position bigger than X2.Among Fig. 1 (a) with extend to the suitable part of the length of the stocking yarn 11 till the pinhock of the knitting needle of yarn until having accepted in the left side of knitting needle 12, therefore, when directly the amount of travel of part that will be suitable with the right side was made as X2, the height of the stocking yarn of supplying with to knitting needle 12 uprised.For the pinhock that makes knitting needle 12s hooks stocking yarn 11s reliably, what need make yarn-feeding port 10 gives the amount of travel X3 on the 10s of yarn position bigger than X2.
In addition, in Fig. 1 (a), on opening etc. under the initial situation of using stocking yarn 11, the maintenances such as yarn gripper that for example are provided with on the end of needle-bar by the left end of figure.The maintenance of the maintenance aspect ratio of the stocking yarn 11 on the end of needle-bar on the shank of the knitting needle that becomes approaching side midway 12 that repeats to weave is highly low.Supplying with under the situation of stocking yarns 11 to knitting needle 12 at first, the amount of travel of yarn-feeding port 10 is set according to the holding position of the stocking yarn on the end of needle-bar 11 and the interval that becomes between the knitting needle that enters side 12 of knitting width.Under making, reduce amount of travel and make and increase amount of travel under this highly lower situation and get final product to the height condition with higher of the stocking yarn 11 of yarn.
Fig. 2 can represent according to the electric formation simplification of summary of the straight-bar machines 20 of giving yarn method supply stocking yarn shown in Figure 1.The needle-bar 21 that left and right directions extends in the straight-bar machines 20 tool digraphs.Needle-bar 21 is provided with in couples in front and back.The needle-bar 21 of front and back is vacated at interval and relatively, the middle tooth mouth 22 that forms.Although omitted diagram, on needle-bar 21, be set up in parallel a plurality of knitting needles with certain needle gage.In the optionally driving of midway carrying out knitting needle of the cam carrier 23 that is mounted with triangle along needle-bar 21 reciprocal walkings.Near needle-bar 21 or its, also be provided with the cam carrier guide rail 24 of the walking of guiding cam carrier 23.Carry out along the driving of the walking of the needle-bar 21 of cam carrier 23 via synchronous belt 26 by motor 25.As motor 25, for example use servomotor.Belt pulley 27 is installed on the output shaft of motor 25, and putting on the shelf at belt pulley is provided with the synchronous belt 26 of non junction shape (ring-type).
Yarn-feeding port 10 is by the track guiding of the carrier rod 31 of the top that is set up in tooth mouth 22, from sagging along left and right directions thread-carrier 33 voluntarily.The height of yarn-feeding port 10 can be made as than height height suitable in the prior art.When making the height of yarn-feeding port 10 higher, even using on each carrier rod 31 under the situation of yarn-feeding port 10 arranging a plurality of carrier rods 31, also can avoid yarn-feeding port 10 to interfere mutually, diverge to the intersection of advancing, and can avoid the interference of yarn-feeding port 10 and the knitting needle that enters with respect to tooth mouth 22.Only show a yarn-feeding port 10 in the drawings, but also can guide same thread-carrier 33 in the inboard of for example carrier rod 31.Under this situation, both sides are respectively equipped with for thread-carrier 33 track voluntarily in the table of a carrier rod 31.In addition, can on perpendicular to the direction of paper, arrange a plurality of same carrier rods 31.
Thread-carrier 33 can drive synchronous belt 36 by motor 35 and walk.Belt wheel 37 is installed on the output shaft of motor 35, on belt wheel 37, is set up synchronous belt 36.Under the situation of using a plurality of thread-carriers 33, use same formation to get final product for each thread-carrier 33.Thread-carrier 33 does not contain the mechanism that yarn-feeding port 10 is moved up and down, and therefore can realize miniaturization, lightweight, alleviates the load of motor 35, can also make thread-carrier 33 walking at a high speed.As motor 35, can use servomotor, stepper motor.
The yarn method of giving shown in Figure 1, the cam carrier 23 that can be undertaken by control device 40 and the walking control of thread-carrier 33 realize.Control device 40 carries out the control of the integral body of straight-bar machines 20, comprises the driver 42 of the motor 25 that drives cam carrier 23 walkings and the driver 43 of the motor 35 that driving thread-carrier 33 is walked.Master controller 41 is set a plurality of woven stitch lines that make cam carrier 23 walkings according to by the decorative pattern data of the knitted fabric of straight-bar machines 20 braidings etc., determines employed knitting needle in each woven stitch line of braiding.Further, the control that master controller 41 walks cam carrier 23 and thread-carrier 33 for driver 42,43 is to form suitable amount of travel for employed each knitting needle of braiding in the timing of hook yarn.
In addition, in Fig. 1 (b), in a woven stitch line, the amount of travel on yarn position 10a, 10d, the 10s of giving of yarn-feeding port 10 is changed to X2 and then changes to X3 from X1, but also can change to X3, or change to X2 from X3 from X1.The change of any amount of travel can both realize by the speed change of yarn-feeding port 10.
