Description
Technical field
The present invention relates to a kind of knitting machine.
Background technology
Motion is imported in the knitting needle of knitting machine into great majority and still realizes by needle cam, its by sledge movements through needle-bar.These needle cams have the shaped form control structure that is used at the pin heel of the selected knitting needle of knitting process.Wherein be devoted to, the least possible knitting needle participates in knitting cycle simultaneously, that is to say, the knitting needle that is pushed out must be pulled as quickly as possible again.This result who causes is, the part that knitting needle retracts will released of shaped form control structure is very precipitous extension.In fact the angle of this shaped form control section just be not changed since initial knitting machine.
In this external straight-bar machines (Flachstrickmaschine), a plurality of Triangulums (Strickschlo β) move through needle-bar, so that the motion that lopping is essential imports in the knitting needle as usual alternately from left to right more from right to left.Therefore in straight-bar machines, these Triangulums must symmetric design.The result who causes like this is, although the speed that the speed of knitting needle when the forward travel that it carries out for lopping is equal to it when pulling back motion is in order to realize that reliable lopping should satisfy the standard that is different from fully when pulling back motion when the knitting needle forward travel.In addition, the forward travel of knitting needle also imports with identical form with the motion of pulling back, although this obviously helps forward travel and the motion of pulling back, if knitting needle can be with variable speed motion.
Realize the defective that pin drives because this class is known for a long time with Triangulum, proposed the knitting machine that single needle drives.This is shown and has described the self-supply type drive unit of each knitting needle that is used for straight-bar machines in EP 0717136A1.Wherein each knitting needle all joins with the linear electric motors coupling, and these linear electric motors can make knitting needle to implement its forward travel and the motion of pulling back with optimized order for lopping and optimized speed through suitably control.Even because under case of machines, also must have more than 1,000 knitting needle motion, so this known solution because the essential linear electric motors of each pin and cost costliness, and requires the control of great number to spend in addition with relatively short needle-bar.These numerous linear electric motors also must be supplied to electric current in addition, thereby the machine energy balance is caused obviously negative influence, and cause producing a large amount of heats.
Described straight-bar machines in DE 19531964A1, settled control guide rod (Steuerschieber) in its balladeur train, the control guide rod can be called in person with its front end form fit ground double team pin, and can be applied effect by stepper motor on its rearward end.Wherein on balladeur train, disposed a plurality of with the spacing identical control guide rod side by side with knitting needle.Import the motion of control in the guide rod into by stepper motor and be transferred on the knitting needle, and drive that these knitting needles stretch out or tractive they return.In order to realize continuous knitting cycle, in known device, be provided with two balladeur trains, these balladeur trains by needle-bar slide up and down the configuration track on.Knitting needle has the pin heel of two mutual dislocation, and wherein the control guide rod of two balladeur trains can act on respectively in one of two pin heels.At first, one of balladeur train is brought to the position, and by its control guide rod knitting needle is moved for lopping, and and then second balladeur train is brought to the position after first balladeur train simultaneously.In case second balladeur train applies effect with its control guide rod to knitting needle, then first balladeur train just moves to the second balladeur train front, so that then can be so that the motion of follow-up knitting needle.
This solution need be than obvious less motor in EP 0717136A1.But two balladeur trains with subordinate drive unit, guiding device and control device must be set, so also still relative both expensive of this solution.
Summary of the invention
The objective of the invention is to, propose a kind of knitting machine, wherein knitting needle can be driven respectively individually and according to the requirement of looped pile forming process in the mode of economical rationality.
This purpose realizes that by a kind of knitting machine this knitting machine has: at least one needle-bar, a plurality of knitting needles are bearing in this needle-bar movable along the longitudinally; At least one needle actuating device, it disposes movingly along at least one needle-bar, it is characterized in that: this needle actuating device has the motor stator of a plurality of arrangements arranged side by side, wherein can be to the rotor that is connected with each knitting needle by each stator
Apply effect.
Therefore in knitting machine of the present invention, any single knitting needle can be controlled according to optimized motion process for the knitting cycle of being sought.Particularly the motion of pulling back of the comparable knitting needle of speed of the forward travel of this knitting needle execution is less.And in forward travel with pull back and also can change speed between moving period.Utilize knitting machine of the present invention can realize than with triangle in addition
As the higher speed of the knitting machine of needle actuating device.Friction phenomenon between the shaped form control structure in pin heel and needle cam has then disappeared in knitting machine of the present invention.Therefore knitting needle also bears less wearing and tearing.Therefore knitting machine of the present invention only is equivalent to the corresponding power that single needle drives among the EP 0717136A1 aspect its power, but has not but had its defective expensive and high current drain.Knitting machine wherein of the present invention not only can be a straight-bar machines, and can be the circular knitting machine with cylindrical shape needle-bar.
One preferred embodiment in, motor can be linear electric motors, the structure of needle actuating device is simplified widely thus.Wherein linear electric motors can be asynchronous or synchronous linear electric motors, and both can be servomotors, also can be stepper motors.
When this needle actuating device by balladeur train when at least one needle-bar can move, then produce additional advantage.Wherein can take on this duty by having Trianguli known knitting machine in the same manner to guiding, supporting and the driving of balladeur train.Certainly also to be provided with a plurality of balladeur trains with a plurality of needle actuating devices.If knitting machine is a straight-bar machines, then can make a plurality of knitted fabrics in this way concurrently.
The design of stator and allocation plan can be selected for use according to corresponding requirement.One may scheme be, all stators all are designed to equal length.This advantage that has is, one type stator need only be provided, and this will make the manufacturing of knitting machine obtain simplifying.
On the contrary, in a kind of alternative design scheme, the length of stator can be different, and adapts to the needle stroke motion that will realize by them.Therefore the structure length of stator can be coordinated mutually with the working region.
Further advantageously, stator is seamlessly closely by putting, that is constitutes the stator bundle, so the rotor of knitting needle always is in the influence area of one of stator.
By stator and the rotor that is connected with knitting needle, not only can but also bed knife can be imported in the knitting needle driving force.Therefore possible is not only to make the knitting needle forward travel and the motion of pulling back, and it is stably remained in the centre position.
When each stator is divided into two and half districts on longitudinal direction, then produce additional advantage, wherein in each half district, can produce the irrelevant electric field in field with other half district.Therefore the rotor of pin can not experience acceleration shock from a stator to the transition of next stator.Or rather, produce uniform knitting needle motion.
In another design of knitting machine of the present invention, this needle actuating device can have a plurality of on the direction of motion of pin stacked stator row, the wherein stator of different lines layout mutually on side direction with staggering.This design helps being used in the very meticulous needle gage situation.Under very meticulous needle gage situation, the rotor of contiguous needles is configured on the different positions, and these positions correspond respectively to the position of one of stator row.Therefore, rotor and stator can have than pin and the big width of pin spacing.
The width of stator must equal the width of rotor at least, but preferably greater than this rotor width.Can guarantee that thus stator can quicken this rotor when slipping over rotor.
For realize with rotor configuration on the knitting needle or with the synergistic control element of knitting needle on, different schemes is provided equally.Rotor for example can be configured in the top side (Oberseite) of shank thus.But need following device in this design, it is fixed in the groove of needle-bar knitting needle when stator movement process rotor, because these stators also apply traction force on rotor.
In another selectivity scheme, rotor can stretch out in this needle-bar in opposite with a pinhock opposed side of at least one needle-bar, and can be applied effect by stator in both sides.Its rotor can directly be configured on the shank or with the synergistic control element of pin on.By the apply effect of stator in both sides, then it is cancelled out each other at epitrochanterian traction force, and being used for of therefore no longer needing to add has been fixed on the device of needle-bar groove with knitting needle.
Knitting machine of the present invention not only can be equipped with latch needles, and can be equipped with compound needle.Under the latch needles situation, the opening movement and the closing movement of this tongue are realized by yarn.Under the compound needle situation, pusher jack (Schieber) opening and closing that must be activated.This needle actuating device can have the additional stator that is used to influence the rotor that disposes on the pusher jack of compound needle for this reason.

The specific embodiment
The schematic diagram of Fig. 1 is with the solid line in the vertical view and be shown in dotted line first embodiment of needle actuating device, and shows the needle cam of the prior art needle actuating device that is used for contrasting with chain-dotted line.
Shown needle actuating device 100 is the needle actuating devices that are used to have the straight-bar machines of latch needles.The stator 1.1-1.19 that it is settled side by side by row constitutes, and these stators are configured on the balladeur train that herein is not shown specifically, and are oriented on the needle movement direction.Stator 1.1-1.19 and rotor 2 synergies, these rotors be fixed on the knitting needle or with the synergistic control element of knitting needle on, wherein only show a pin heel 51 herein.Stator 1.1-1.19 and rotor 2 common formation linear electric motors.The needle cam 60,61,62,63 that stator 1.1-1.19 and rotor 2 replace with the conventional needle drive unit shown in the chain-dotted line, and imitate its driving in the best way to each knitting needle.
The needle cam 60-63 that disposes on the cam base plate that is not shown specifically herein for example moves through this needle-bar on direction of arrow SB from right to left by balladeur train.This motion Once you begin just imports to the forward travel on the arrow V direction in the pin heel 51 by enduring pin part 60, and this pin heel is brought on the pin heel original position NFG by unshowned needle cam.Therefore knitting needle also is pushed forward on arrow V direction.Till when this forward travel continues to pin heel 51 and has arrived its highest progressive position NFH.Then, the shaped form control structure that is made of needle cam 60 and 61 that is used for pin heel 51 forces knitting needle to carry out the motion of pulling back on the arrow R direction.Then, this is pulled back and moves through cast-off cam (Nadelsenker) 63 and proceed.When pin heel 51 arrived knitting position (Kulierposition) NFK, the maille that then new having pre-determines size had just formed.With regard to described new knitting needle drive unit with stator 1.1-1.19, can imitate this motion process of knitting needle.If balladeur train moves on arrow SB direction, then the feasible rotor 2 that is configured in the pin heel 51 of stator 1.1-1.9 carries out the forward travel on arrow V direction.Wherein stator 1.1-1.19 at first takes rotor 2 on the position corresponding with pin heel position NFG.Then, stator 1.4-1.10 takes rotor 2 on the position corresponding with pin heel position NFH to.This is pulled back and moves through stator 1.11-1.19 and realize, on rotor places position with pin heel position NFK correspondence.So this knitting cycle finishes.
Yet needle actuating device 100 not only can be imitateed the motion process of needle cam 60-63, and can realize that explaining the knitting needle that shows optimization for lopping moves.Can import knitting needle motion in each stator 1.1-1.19, the speed of knitting needle motion is in the knitting needle forward travel and to pull back between moving period for knitting cycle be good.The acceleration of knitting needle and deceleration equally can be than realizing of finishing by the panelling (Schlosskurven) of machinery more neatly.The motion of pulling back of knitting needle can realize more apace that the knitting needle number that therefore participates in the kinking process obtains reducing, and this forms the positive effect that produces for looped pile.And the stroke that knitting needle is passed by can obtain shortening.
By stator control, in conjunction with balladeur train control, can realize at random almost that knitting needle moves, can realize new, also not known knitting method now thus.
Owing to saved the friction between pin heel 51 and the needle cam 60-63, can improve knitting speed significantly.Also reduced the noise that machine produces simultaneously.
Fig. 2 shows the part of knitting needle drive unit 100, and is along the partial side view of this knitting machine on the arrow directions X among Fig. 1.Can see needle-bar 40 and knitting needle 50 from this side view, this knitting needle is positioned in the groove 41 of needle-bar 40.In the pin heel 51 of pin 50, fixed to form fit rotor 2.The segmentation 22 of rotor grips the pin heel 51 of pin.The connection of this form fit is through suitably design, and feasible possible angular error with respect to stator 1.1-1.19 can be compensated.Form air-gap 102 between the active layer 11 of the body of rotor 2 and stator 1, this stator is fixed on the balladeur train 30.Stator 1 imports to motion on the rotor 2 in contactless mode.
The stator 1.1-1.19 of needle actuating device 100 is designed to the structure of whole equal length, therefore only needs one type stator.In contrast, Fig. 3 shows the needle actuating device 100 ' with stator 1.10-1.19, and the length of these stators is different, and selects for use according to the corresponding work zone of stator.Stator 1.10 and 1.11 has maximum working region, therefore also has the longest structure length L.The length L 1-L7 of stator 1.12-1.19 then is short by comparison.The whole stator surface of this needle actuating device 100 ' is less with respect to the stator surface of needle actuating device among Fig. 1 100 equally.
The detail view of needle actuating device 100 ' shows the course of work of this needle actuating device 100 ' among Fig. 4, and in addition, the method for operation of this course of work and needle actuating device 100 are equal to.What this Figure illustrates rotor 2 is applied motion between action period at it by stator 1.18.The unshowned herein balladeur train of stator 1.1-1.19 that has is between the moving period on the arrow SR direction, stator 1.19 advances on the VT1 of position rotor 2 on arrow V direction, and suitably motion is through rotor 2, makes that limit, the longitudinal side B19 of limit, the longitudinal side b of rotor 2 and stator 1.19 is overlapping.Stator 1.19 is fixed on rotor 2 among the VT1 of position, as long as it can affact on the rotor.The balladeur train that has stator continuing on the arrow SR direction motion through stroke SB-the trip corresponding to the width of stator-during, stator 1.18 will little by little cover rotor 2, and apply bed knife thereon.In case limit, the longitudinal side A18 of the longitudinal axis a of rotor 2 and stator 1.18 is overlapping, then stator 1.18 just makes rotor 2 move to position VT2 on arrow V direction.Suitably move through rotor 2 at this this stator 1.18, overlapping until limit, the longitudinal side B18 of limit, the longitudinal side b of rotor 2 and stator.Then, this stator 1.18 is fixed among the VT2 of position rotor 2, fully moves through rotor until it.Between balladeur train continued moving period along arrow SR direction, follow-up stator 1.17-1.11 applied effect in the mode identical with stator 1.18 to rotor 2.
If balladeur train moves on arrow SL direction, then knitting needle is carried out the motion of pulling back.In this case, stator 1.17 makes rotor 2 be pulled among the VZ1 of position last time in arrow R direction, and suitably moves through rotor 2 at this, makes that limit, the longitudinal side A17 of limit, the longitudinal side a of rotor 2 and stator 1.17 is overlapping.Continue motion through during the rotor 2 at stator 1.17, it is fixed on rotor among the VR1 of position, as long as also exist lid folded between stator 1.17 and rotor 2.
Balladeur train continued to move width through stroke SB that is stator along arrow SL direction during, 1.18 of stators little by little covered rotor 2, and effect bed knife thereon.In case limit, the longitudinal side B18 of limit, the longitudinal side b of rotor 2 and stator 1.18 is overlapping, then this stator just makes rotor 2 move among the RZ2 of position along arrow R direction.Suitably move through rotor 2 at this this stator 1.18, overlapping until limit, the longitudinal side A18 of limit, the longitudinal side a of rotor 2 and stator.As long as this stator 1.18 also partly covers rotor 2, it just is fixed on rotor among the RZ2 of position.Balladeur train along arrow SL direction-it is not shown herein-situation that continues to move under, this stator 1.19 applies effect in the mode identical with stator 1.18 to rotor 2.
Be appreciated that and disposing symmetrically with respect to Fig. 4 mirror under the situation of stator that the forward travel of rotor 2 can realize by the motion of balladeur train in arrow SL direction, and rotor 2 pull back that then the motion on arrow SR direction realizes by balladeur train in motion.
Be loaded with the balladeur train of stator 1.1-1.19 can step-less adjustment to predetermined high-speed motion through rotor 2.Wherein these stators can on any position of its resulting structure length, make rotor 2 forward travels, pull back the motion or be fixed on their positions.Under the forward travel and the motion conditions of pulling back of rotor 2, these stators can make the motion of rotor 2 step-less adjustment ground, until predetermined speed.
By control corresponding, just can realize being used for all motion processes that can expect of knitting needle to sledge drive and stator.
The width S B of stator 1.1-1.19 must be greater than the width LB of rotor 2.Wherein width S B determines according to ' maximum rotor movement travel/each stator ' with respect to the ratio of SL, by the acceleration possibility and the deceleration possibility of stator, determined by attainable spinner velocity and maximum carriage speeds.
Fig. 5 show this needle actuating device 100,100 ' course of work with the quite big degree of Fig. 4 on consistent description figure, wherein knitting needle should be fixed on the predetermined position of its moving region.Wherein having described rotor 2 by way of example is being fixed on during its time of staying below the stator 1.18.On the arrow SR direction between moving period, stator 1.19 makes rotor 2 move among the HP of position at the balladeur train that has stator 1.1-1.19, and rotor should be fixed in this position.At this, this stator 1.19 suitably moves through rotor 2, makes that limit, the longitudinal side B19 of limit, the longitudinal side b of this rotor 2 and stator 1.19 is overlapping.This stator 1.19 just is fixed on rotor 2 among the HP of position as long as rotor 2 is in the field of stator 1.19.
Continue to move along arrow SR direction through under stroke SB that is the stator width situation at balladeur train, 1.18 of this stators little by little cover rotor 2, and have strengthened its bed knife to rotor 2.In case limit, the longitudinal side A18 of limit, the longitudinal side a of rotor 2 and stator 1.18 is overlapping, then stator 1.18 is acting on the strongest bed knife on rotor 2.Then, this bed knife no longer changes, and suitably moves through rotor 2 until stator 1.18, makes that limit, the longitudinal side B18 of limit, the longitudinal side b of rotor 2 and stator is overlapping.In a word, stator 1.18 is as long as it can affact on the rotor and just be fixed on the predetermined position.
If balladeur train continues motion on arrow SR direction, then stator 1.17 just applies effect in the mode identical with stator 1.18 to rotor 2, if knitting needle also should be fixed in the unaltered position.This presses connotation and also is applicable to every other stator.
Because rotor 2 reduces in the time degree that covered by follow-up stator 1.17 and compared to some extent by the degree that previous stator 1.18 covers that carries out the transition to next stator 1.17 from a stator 1.18, pretend the bed knife that is used on the rotor 2 and always remain unchanged.
Fig. 6 shows another needle actuating device 100 " with the quite big degree of Fig. 4 on consistent description figure, the difference of itself and needle actuating device 100 and 100 ' is that each stator 1.1-1.19 is divided into two and half district A and B in the vertical.Each partly distinguishes A and B can control with being separated.Therefore rotor just can be realized as below will being described from a stator to next stator transition, and does not have acceleration shock on rotor 2:
At the unshowned balladeur train of stator that has between the moving period on the arrow SR direction, in the example shown, stator 1.19 makes rotor 2 advance on arrow V direction and moves among the VT1 of position, and at first suitably move through rotor 2 with its A that partly distinguishes then with its B that partly distinguishes at this, make that limit, the longitudinal side b of rotor 2 and the boundary line G1 between two stators 1.18 and 1.19 are overlapping.
The most late this time point, stator 1.18 partly distinguish B through suitably control, make rotor 2 and on identical direction, to move with the identical speed of A of partly distinguishing by previous activation stator 1.19.The balladeur train that has stator continues to move through stator width FB along arrow SR direction with Qi Ban district A and B during, partly the distinguishing B and will little by little cover this rotor of this stator 1.18, and therefore also bear the forward thrust to rotor 2 of increase.In case limit, the longitudinal side b of rotor 2 and stator 1.18 partly distinguish boundary line G2 overlaid between the B He Ban district A, the A that partly distinguishes of this stator 1.18 also is activated, and the only still forward travel by stator 1.18 of rotor 2.
If balladeur train continues to move on arrow SR direction, then stator 1.18 continues rotor 2 to be driven among its progressive position VT2 along arrow V direction.At this, these stator 1.18 motions are through rotor 2, and until limit, the longitudinal side b of rotor 2 and the boundary line G3 overlaid between stator 1.18 and 1.19, and this rotor fully is in the Ban Qu a-quadrant of stator 1.18.If balladeur train continues to move on arrow SR direction, then stator 1.17 will apply effect in the mode identical with stator 1.18 to rotor 2, and this is equally applicable to all follow-up stators.
Under the situation that balladeur train moves in the opposite direction, the A that partly distinguishes that at first activates stator 1.19-1.17 activates half district B then.So this rotor 2 is carried out to pull back and is moved but not forward travel.
Figure 7 illustrates the needle actuating device 100 of corresponding description with Fig. 1 " ', wherein needle actuating device 100 " ' be considered for having the straight-bar machines of compound needle.Be provided with two row stator 110N and 110S.Stator row 110N so is fixed on the unshowned herein balladeur train, makes these stators with length SLN the pin forward travel and the motion of pulling back can be imported in the rotor 2 that is connected with unshowned aciculiform shape.
On the contrary, stator row 110S is fixed on the balladeur train at one determining deviation A place, stator row 110N front, can import in the rotor 2 ' that is connected with pusher jack (Schieber) form fit of knitting needle with the pinhock closing movement open motion for the necessary pinhock of knitting process thereby these row have the stator of length SLS.The stator row
The spacing A of 110N and 110S depends on the spacing of pin heel with respect to the pusher jack heel, has disposed rotor 2 in the pin heel, has fixed this rotor 2 ' in the pusher jack heel.
The length SLS of pusher jack-stator is suitably selected, and makes that this pusher jack can be opened or be closed on any position that knitting needle may be in its motion process.
Under modern compound needle situation, this pusher jack by frictional fit be bearing in the needle body, so pusher jack can automatically remain on its position that is determined in advance, as long as it is not applied effect by needle cam.Adopting under this compound needle situation, these stator row 110S can pass through appropriate structuring, makes not to be that all stators are all settled mutually with being directly adjacent to.Or rather, they can be by configuration set in the place that must realize the pusher jack motion.The length SLS of stator will coordinate mutually with the pusher jack movement travel that will realize.
Figure 8 illustrates the side view of the needle actuating device 100 ' of Fig. 3.Rotor 2 is configured under this needle actuating device 100 ' situation on the knitting needle in needle-bar 40 zone.Therefore this needle actuating device only can be applicable to following knitting machine, and promptly the spacing of its pin and pin is greater than the width LB of the body 21 of rotor 2.This needle actuating device 100 ' needs aforesaid stator row 110.All knitting needles maybe import motion into the control element on the knitting needle, all have identical length.
In contrast, Fig. 9 shows the side view of needle actuating device 130, and it can be applicable to following knitting machine, and promptly the spacing of its pin and pin is less than the width LB of the body 21 of rotor 2.For this reason, this needle actuating device 130 has a plurality of stator row 110, and these stators are listed as with predetermined mutual spacing and are parallel to the configuration successively successively of needle-bar longitudinal side ground.In described present embodiment, three row 110,110 ', 110 " be fixed on the balladeur train 30.110 pairs of rotors 2 of stator row apply effect, and stator row 110 ' apply effect to rotor 2 ', stator row 110 " to rotor 2 " apply effect.Import in the knitting needle motion and the control element or the knitting needle that are connected with rotor 2, have the shortest structure length.The control element or the knitting needle that are connected with rotor 2 ' have medium structure length, with rotor 2 " control element that is connected and knitting needle have maximum structure length.Wherein knitting needle or control element suitably are configured in the groove of needle-bar, make knitting needle or the control element that the knitting needle be connected with rotor 2 or control element heel are connected with rotor 2 ', thereafter heel and rotor 2 again " knitting needle or the control element that are connected.Between continuation moving period of balladeur train 30, by stator row 110 motion is imported in the rotor 2 successively, by stator row 110 ' motion is imported in the rotor 2 ' then, and by stator row 110 " import motion into rotor 2 " in, wherein this order reruns constantly.
Figure 10 illustrates the side view of another needle actuating device 140.So far described needle actuating device 100,100 ', 100 ", 130 differences, under needle actuating device 140 situations, this rotor 2 is configured in the outside of needle-bar 40.Wherein each rotor 2 all passes through shank 23, and by unshowned, the shape syndeton of coincideing preferably, the control pusher jack (Steuerplatine) that maybe motion is imported on the pin with pin is connected.On end face, this rotor 2 has body 21, and has another body 21 ' on its bottom surface.The structure of two bodies 21,21 ' is identical.
For rotor 2 is applied effect, balladeur train 30 is loaded with the first stator row 110 of effect that the body 21 of rotor 2 is applied on its medial surface 31, and is loaded with another stator row 110 ' of effect that the body 21 ' of rotor 2 is applied on its medial surface 32.Two bodies 21,21 ' are applied effect simultaneously and synchronously by stator row 110,110 '.Just cancelled out each other thus perpendicular to the power that stator acts on the rotor 2.Therefore just need not those under needle actuating device 140 situations must bear the mechanical device of these power.
