Description

Straight-bar machines and used the traversing braid method of straight-bar machines
Technical field
The present invention relates to the braid method on the straight-bar machines, particularly relate to the traversing braid method of the mobile and needle-bar that has used cam carrier.
Background technology
The productivity ratio of straight-bar machines and cam carrier are proportional with respect to the speed of needle-bar.This be because, the quantity of the pin of cam carrier operation is proportional with the speed of cam carrier, and the quantity of the coil that is woven by the quantity decision of the pin of cam carrier operation.Therefore, make the cam carrier high speed can improve braiding speed, but cam carrier is the heavier parts of the cam system that possesses the operation pin, the selecting mechanism that reaches which pin that determines the operation needle-bar etc., there is restriction in high speed.
If show relevant prior art, can enumerate patent documentation 1:JP1996-13294A and disclose each shog technology freely that makes the straight-bar machines front and back here.And traversing itself be known, for example can make four needle-bars all traversing straight-bar machines also be known.Traversing being mainly used in makes coil move on needle-bar, and the length that can make shog for example is about 2 inches, and the speed of the needle-bar in traversing is for example about 1/10 of cam carrier speed.Traversing in addition cam carrier break away from knitting width and carry out between reversal stage, carry out simultaneously coil formation and traversing be ignorant.
Patent documentation 1:JP1996-13294A
Summary of the invention
Problem of the present invention is to improve braiding speed through increasing cam carrier with respect to the speed of the pin of needle-bar.
The present invention provides a kind of straight-bar machines, comprising:
At least one needle-bar has a plurality of pins, moves freely in the longitudinal direction;
Cam carrier moves along the length direction of needle-bar, the pin of operation needle-bar and making knit fabric; And
Controller, control cam carrier and needle-bar, said straight-bar machines be characterised in that,
Be provided with the needle-bar control module, in order to weave, cam carrier move and make advance before and after the pin of needle-bar in, needle-bar is moved to the opposite direction of the moving direction of cam carrier.
Preferably; During moving on the knitting width of cam carrier at knitted fabric; The needle-bar control module makes needle-bar move continuously to the opposite direction of cam carrier, and thus, cam carrier weaves with the speed of needle-bar speed and cam carrier speed sum.
In addition, preferably, during moving on the knitting width of cam carrier at knitted fabric, the needle-bar control module makes needle-bar move to the opposite direction of cam carrier, while and make the needle-bar velocity variations that needle-bar is moved.
For example the needle-bar control module speed that makes needle-bar is bigger than the speed between acceleration region and deceleration zone on the acceleration region of cam carrier and deceleration zone.
In addition, for example, from jersey on the change circle that rib fabric changes, the needle-bar control module makes needle-bar speed littler than the needle-bar speed on the jersey.Here, if increasing needle-bar speed to the change circle that jersey changes, the consumption of yarn is reduced, and correspondingly prevent the yarn residue from rib fabric.
For example, the needle-bar control module is compared when carrying out the little operation of load to yarn when cam carrier carries out the big operation of load to yarn, reduces needle-bar speed.
The present invention also provides a kind of braid method, uses the straight-bar machines that comprises following parts:
At least one needle-bar has a plurality of pins, moves freely in the longitudinal direction;
Cam carrier moves along the length direction of needle-bar, the pin of operation needle-bar and making knit fabric; And
Controller, control cam carrier and needle-bar, said braid method be characterised in that,
In order to weave, cam carrier move and make advance before and after the pin of needle-bar in, needle-bar is moved to the opposite direction of the moving direction of cam carrier.
In addition, in this specification,, on the contrary, also directly be suitable for controlling organization based on the controller of straight-bar machines about the record of braid method about the record of straight-bar machines and the needle-bar braid method mobile simultaneously that directly is suitable for making straight-bar machines with cam carrier.
The invention effect
Among the present invention, cam carrier moves with cam carrier self speed and the needle-bar speed sum pin with respect to needle-bar.Therefore the cam carrier speed more independent than cam carrier with respect to the speed of pin is big, and the stroke of the stroke ratio needle-bar of cam carrier is short.Therefore can not increase the cam carrier self speed and improve braiding speed.And owing to do not increase the cam carrier self speed, so the vibration of cam carrier do not increase yet, and need not strengthen the driving mechanism of cam carrier yet.And the time that is used to cam carrier is reversed on needle-bar is not elongated yet.And at cam carrier when the direction of drawing yarn moves, can shorten the length of drawing yarn and reduce load yarn.For example can directly use existing traversing mechanism in the moving of needle-bar, also can increase the traversing width and the translational speed of needle-bar, further improve braid efficiency from existing straight-bar machines.About the moving of needle-bar, traversing and mobile is the same meaning in addition.
Mobile time is about equally on the maximum sideslip width at the time of moving on the knitting width of knitted fabric and needle-bar for example to establish cam carrier.Under this situation, preferred cam carrier makes needle-bar roughly move to constant speed to the opposite direction of cam carrier during moving on the knitting width of knitted fabric.Here, the speed of establishing with needle-bar speed and cam carrier speed sum weaves, and needle-bar speed, is that traversing speed is for example 1/10 of cam carrier speed, and then braiding speed improves about 10%.
Cam carrier is different for the response performance of speed controlling with needle-bar.If stop and maximum speed between the acceleration and deceleration time estimate response performance, then the cam carrier with high-speed mobile is generally low than needle-bar response performance.This makes cam carrier move this above-mentioned control with respect to pin with the aggregate velocity of cam carrier self speed and needle-bar speed becomes possibility.For example if the deficiency of the acceleration and deceleration performance of the acceleration and deceleration performance compensation cam carrier through needle-bar, the vibration that then can not increase cam carrier, and drive cam carrier with the high acceleration and deceleration on apparent.
For example weave in the high-quality knitted fabric, cam carrier is moved at the uniform velocity weave, preferably do not weave in the interval that cam carrier carries out acceleration and deceleration.This is in and makes needle-bar with big speed action when cam carrier quickens, and when quickening to finish, reduces needle-bar speed.And when cam carrier slows down, make needle-bar with big speed action.So, cam carrier with respect to the velocity mode of the pin of needle-bar near square wave, initial in the end of acceleration region and the zone of slowing down, cam carrier moves near movement at the uniform velocity on apparent.Therefore having enlarged can be with the scope of stable quality making knit fabric, and the actual acceleration-deceleration of cam carrier do not increase, and does not therefore become the reason of vibration.
In jersey and the rib fabric, the consumption of the yarn of every knitting width is different, the yarn that need Duo than jersey in the rib fabric.Therefore knit stitches is when jersey becomes rib stitch, and the undersupply of yarn brings bigger load to yarn.Therefore if, then can reduce braiding speed partly, reduce load to yarn reducing needle-bar speed to the change circle that rib fabric changes from jersey.
In addition, when carrying out the bigger operation of load to yarn,, then can prevent the yarn disconnection if reduce needle-bar speed or make needle-bar to move with cam carrier is equidirectional.For example on the pin that keeps a plurality of tucks, weave, bigger to the load of yarn.When carrying out this operation more lentamente, the load of yarn is reduced.In addition when fancy yarn etc. is used in braiding than the coil of tender yarn line, reduce braiding speed if compare during with other coils of braiding, can prevent that then yarn from breaking off.Except preventing that yarn from breaking off, if when carrying out more difficult knit operation, reduce the speed of cam carrier with respect to pin, then braiding becomes easy.

Embodiment
The braid method of the straight-bar machines 2 of expression embodiment and embodiment among Fig. 1~Fig. 7.Among each figure, the 4, the 6th, needle-bar, the 4th, back needle-bar, the 6th, preceding needle-bar.Needle-bar 4 is freely traversing through motor M2 and not shown ball-screw etc., and needle-bar 6 is likewise freely traversing through motor M3 and ball-screw etc.If traversing direction is the length direction of needle- bar 4,6, with respect to the reference position for example to the right 1 inch, 1 inch to the left, add up to traversing 2 inches etc.± 1 inch traversing is according in once-through operation, making the traversing moving length of coil wait to confirm, also can for example ± 5 making needle- bar 4,6 traversing on inch stroke that grade is bigger.Among the embodiment, except utilize needle-bar 4, barring-on and situation that coil is moved between 6 on the length direction of needle- bar 4,6, needle- bar 4,6 moves to equidirectional with constant speed simultaneously.Therefore needle-bar 4, relatively moving between 6 be can not produce, ribbed knitting and needle-bar 4, the barring-on between 6 easily carried out.
One of needle- bar 4,6 only can be traversing situation under, be suitable for embodiment when on needle-bar that can be traversing, weaving.This is external only to use as plain stitch under a side the situation of needle-bar, also can only make the shog of locking pin fabric.And knownly possess four needle-bars, make all traversing straight-bar machines freely of these needle-bars.Known in addition possess the auxiliary also traversing straight-bar machines freely of needle-bar such as two barring-on needle-bars etc. and barring-on needle-bar except that two needle-bars.Also can likewise be suitable for embodiment for these straight-bar machines.
The 8th, cam carrier, the length direction on the top of needle- bar 4,6 along needle- bar 4,6 moves, and for example moving of cam carrier 8 carried out through utilizing motor M1 to drive cingulum 10.The 12nd, the controller of straight-bar machines; Possess LAN interface 14, data parsing portion 16 and pattern generation portion 18; LAN interface 14 and not shown LAN between carry out input and output of weave data etc., also can replace LAN interface 14 and read in weave data through disc driver etc.Data parsing portion 16 resolves weave datas, shift motion, the cam carrier 8 of inspection cam carrier 8 move during knit stitches variation and have or not the difficult braiding of operation etc.
Pattern generation portion 18 generates the velocity mode of cam carrier 8, the velocity mode of needle- bar 4,6 according to the parsing of the weave data in the data parsing portion 16.Data parsing portion 16 and pattern generation portion 18 also can be arranged at the design apparatus that generates weave data in addition.The velocity mode of the analysis result of weave data and their pattern regulation cam carrier 8 and needle-bar 4,6.For example the length direction along straight-bar machines 2 is provided with not shown gauge, detects the position of cam carrier 8 with respect to gauge.Then as being the pattern of benchmark, generate velocity mode, and the velocity mode of needle-bar of cam carrier with the position of the cam carrier on the gauge.This external schema generation portion 18 is corresponding to the needle-bar control module.The 20th, thread-carrier is supplied with stocking yarn from sidepiece stretcher 22 grades to the pin of needle-bar 4,6.Thread-carrier 20 generally exists a plurality of, but here only illustration one.
Speed controlling portion 24 is through control motor M1~M3, according to the velocity mode that generates by pattern generation portion 18, and the walking of control cam carrier 8 and needle- bar 4,6 traversing.The needle selecting device in the cam carrier controller 26 control cam carriers 8 that are provided with on the cam carrier 8 and the knitting cam of control pin use gauge 28, obtain the position of cam carrier 8 with respect to straight-bar machines 2 main bodys.The position of obtaining from gauge 28 being added the amount after the traversing amount of upper stitch bed 4,6, is the position of cam carrier 8 with respect to needle-bar 4,6.It is traversing in the other direction with needle- bar 4,6 to establish cam carrier 8 here.
Needle selecting device is configured in the both sides of knitting cam along the direction of travel of cam carrier 8.When cam carrier 8 moves, select the pin that carries out the pin of tuck and carry out lopping, barring-on etc. by needle selecting device on needle-bar 4,6.Cam carrier 8 operates in the pin of selecting in tuck, the lopping etc. through knitting cam, after from needle- bar 4,6 outstanding modes it being advanced, it is retreated, and carries out the formation of coil etc.And the needle selecting device at the rear through knitting cam select next pin that is operating as lopping, barring-on, tuck etc., and in not weaving inactive pin.Speed controlling portion 24 is imported the position of cam carriers 8 with respect to the straight-bar machines main body from cam carrier controller 26; Additional calculation is carried out in position to the needle- bar 4,6 obtained by encoder or the not shown sensor of motor M2, M3; Obtain the position of cam carrier 8, to cam carrier 8 outputs with respect to needle- bar 4,6.
Fig. 2 schematically representes the traversing scope of needle-bar 4,6.30,31 expressions are to the traversing to greatest extent needle-bar in left side of figure, and 32,33 represent traversing to greatest extent to the right needle-bar.The solid line of figure representes to be in the needle- bar 4,6 of normal place.Needle- bar 4,6 to the left side of figure and to the right all can be traversing for example each 1 inch, add up to 2 inches.Certainly increase traversing stroke, more more effectively embodiment of the present invention more.The speed of travel of cam carrier 8 for example is about 1~2m/s, the traversing speed of needle- bar 4,6 for example be its about 1/10.Because cam carrier 8 is walked with permanent speed at a high speed, and is therefore longer from stopping to the acceleration and deceleration time of permanent speed.Relative therewith, the speed of needle- bar 4,6 when traversing is less, so the acceleration and deceleration time is shorter.In addition, cam carrier 8 is because so that walking thereby vibration are also bigger at a high speed, but needle- bar 4,6 is owing to move and be supported on the not shown straight-bar machines main body needle-bar through ball-screw etc., and therefore vibration is also less.In other words, needle- bar 4,6 is compared cam carrier 8, and is higher for the response performance of speed controlling.
Fig. 3 representes that knitting width for example is a velocity mode more in short-term, cam carrier and needle-bar about 5~15 inches.The solid line of figure is represented the speed of cam carrier, and needle-bar and cam carrier are in the opposite direction, and the needle-bar before and after making moves with identical speed.The chain-dotted line of figure is represented the speed of cam carrier with respect to the pin of needle-bar, and this is the aggregate velocity of cam carrier speed and needle-bar speed.This some be common in Fig. 3, Fig. 4 and Fig. 6, Fig. 7.Be woven in cam carrier and carry out, make roughly constant speed ground motion of needle-bar for the Zone Full of knitting width with respect to the interval of the speed constant of pin.Therefore as from shown in solid line to the single-point line of Fig. 3, the speed of the cam carrier on apparent, to be cam carrier increase with respect to the speed of pin, and correspondingly braiding speed improves.In addition owing to be not to increase actual cam carrier speed, so the vibration of cam carrier do not increase, and required time of the cam carrier action, i.e. the counter-rotating action that stop, quickening once more and reverse after slowing down is not long yet.
Fig. 4 representes that knitting width is the example of the velocity mode for example more than 20 inches the time.Because on the beginning zone of the end region of the acceleration of cam carrier and deceleration is not movement at the uniform velocity, therefore worries to influence when weaving the quality of knitted fabric.Because needle-bar is with the response performance generation velocity variations faster than cam carrier, therefore in the acceleration region of cam carrier and deceleration zone temporarily with big speed drive needle-bar.So, cam carrier with respect to the relative velocity of pin shown in the chain-dotted line of Fig. 4 near square wave, can weave with stable quality with the initial of the zone of slowing down at the end of acceleration region.50, the 51st, can increase the zone of knitting width.The length that needle-bar moves during making the cam carrier acceleration and deceleration is compared generally shorter with the stroke of needle-bar, therefore remaining stroke is allocated in the interval that cam carrier moves at the uniform velocity.As a result,, also can increase the speed of cam carrier on apparent, improve braiding speed even in the interval that cam carrier moves at the uniform velocity.
As stated, under the knitting width situation narrower, can make the at full throttle traversing situation of needle- bar 4,6 more on the whole at knitting width than setting.Under the knitting width situation narrower than setting; With at acceleration region and the deceleration zone is at full throttle traversing compares; Preferably at full throttle traversing with respect to knitting width integral body, and only reducing traversing speed or the traversing direction of reversing to the change circle of rib fabric variation and the position that is difficult to weave from jersey.Be under the situation more than the setting at knitting width on the contrary, when making needle- bar 4,6 at full throttle traversing with respect to knitting width integral body, the situation that surpasses length that can be traversing is more.At knitting width is under the situation more than the setting; Preferably at full throttle traversing at acceleration region and deceleration zone; Other zones at knitting width are traversing with the speed littler than maximum speed; From jersey on change circle that rib fabric changes and the position that is difficult to weave, reduce traversing speed or the traversing direction of reversing.
Effect through representing with the relation of thread-carrier 20 needle- bar 4,6 and cam carrier are moved among Fig. 5.Here, establish thread-carrier 20 and emit yarn from the sidepiece stretcher 22 in left side, cam carrier moves right from figure left-hand figure, and needle- bar 4,6 moves left from figure dextrad figure.60, the 61st, knitting width uses pin and the making knit fabric of this scope, and the 62, the 63rd, there is not the configuration of the needle-bar when traversing.Needle- bar 4,6 moves left from figure dextrad figure, so the shift motion of thread-carrier 20 shortens, and for example stroke shortens the amount from the thread-carrier position shown in the dotted line of Fig. 5 to the thread-carrier position shown in the solid line.Therefore emit the contraction in length of yarn via sidepiece stretcher 22, can reduce load yarn.
The control of the traversing speed that Fig. 6 representes to accompany with the change of knit stitches.The yarn consumption amount of every knitting width is less on the jersey, and the yarn consumption amount of every knitting width is bigger on the rib fabric.Therefore from jersey when rib fabric changes, temporarily not enough from the quantity delivered of the yarn of thread-carrier, yarn is applied load.Therefore if side by side reduce needle-bar speed with changing to rib fabric, then can temporarily reduce braiding speed, reduce the load of yarn in this part from jersey.And from rib fabric when jersey changes, the yarn consumption amount reduces, therefore temporarily between thread-carrier and needle-bar yarn become superfluous.Therefore from rib fabric when jersey changes, if the temporary transient translational speed that increases needle-bar, then can reduce the surplus of yarn.In the example of Fig. 6 also be, in the acceleration region of cam carrier and the temporary transient traversing speed that increases needle-bar in the zone of slowing down, the interval lengthening that cam carrier moves at the uniform velocity with respect to the pin of needle-bar, knitting width increases.Make length that needle-bar moves than under the short situation of the range of needle-bar through the acceleration and deceleration of accompanying with the variation of the right ends of knitting width, knit stitches; Utilize remaining stroke that needle-bar is roughly moved at the uniform velocity to the opposite direction of cam carrier, the braiding speed on the cam carrier increases.
Velocity mode when Fig. 7 representes to carry out the bigger braiding of load to yarn.When for example continuous a plurality of rows form tuck on same needle and since in the tuck old coil not from the pin knocking over, so on a pin, keep multiple coil.As a result, the load for yarn becomes big, yarn disconnection sometimes.And unactual to the speed of every pin change cam carrier, needle-bar, therefore for comprising the interval of carrying out, compare other intervals and reduce braiding speed the pin of the bigger operation of the load of yarn.
Fig. 7 representes the pattern of the shog speed on this interval.Temporarily increase the speed of needle-bar at the two ends of knitting width, increase interval with respect to cam carrier and the motion of pin constant speed ground.Then, needle-bar and cam carrier are moved to equidirectional, reduce the superficial velocity of cam carrier in the interval of loading big braiding.The remainder stroke of needle-bar is allocated in other intervals comparably, increases the apparent translational speed of the cam carrier on the little interval of load.So in the big operation of load, with respect to the little operation of load, the translational speed of cam carrier reduces about 20%, can prevent that yarn from breaking off on apparent.In addition as stated, cam carrier is high less than needle-bar for the response performance of velocity mode.Therefore replace carrying out speed controlling through cam carrier, it is easier to carry out speed controlling through needle-bar.
Among the embodiment, the velocity mode of needle-bar and cam carrier has been represented a stroke, but in the actual braiding, row of every pair of knitting width braiding of cam carrier and needle-bar is just to the opposite direction action of reversing.As a result, with the velocity mode speed reversal direction of Fig. 3, Fig. 4, Fig. 6, Fig. 7 and when repeating to move, can make cam carrier and needle-bar carry out reciprocating action repeatedly.
Obtain following effect among the embodiment.Increase the translational speed of cam carrier, can increase braiding speed with respect to pin.Like this, need not increase the actual speed of cam carrier, therefore vibration does not increase, and is used to make the time of cam carrier counter-rotating not increase yet.And can be in the amount of drawing of the yarn that when thread-carrier is drawn yarn, reduces cam carrier when walking.Can shorten the stroke of cam carrier in addition.And it is higher to utilize needle-bar and cam carrier to compare the response performance of velocity variations, enlarges cam carrier and carries out the interval of constant speed walking with respect to pin, or is absorbed in the not enough or superfluous amount of the yarn on the variation part of knit stitches.And, can temporarily reduce the speed of cam carrier for the interval of the operation that is difficult to weave.
