Technical field
The present invention relates to quilting, particularly relate to the high speed multi-needle quilter and carry out quilting.More specifically, the present invention relates to the spininess chain stitch quilter, for example, other quiited products of manufacturing External cover of bed-mattress and broad-width multi-layer cloth and making.
Background technology
Quilting is a kind of sewing technology, textiles or other tissue layer can be combined thus, for the production of have ornamental and functional compressible material piece (panel) simultaneously.Stitching (stitch) pattern is for decorating the material piece with sewn designs, each layer of cloth that while stitching itself will be made quilt combines.Manufacture External cover of bed-mattress and comprise the extensive quilting technique of use.Large-scale quilting technique is used the high speed multi-needle quilter usually, along the band material of multilayer cloth, forms a series of External cover of bed-mattress.These extensive quilting techniques are used the chain-type stitch sewing head usually, and formation can be by the elasticity stitching chain of large bobbin thread supply.Some such machines can move under up to 1500 pins per minute or higher speed, drive a line or multirow pin at every turn, thereby stitch out pattern on 90 inches of width or wider band material simultaneously.In bed in the quilting technique of articles for use industry, persevering target is higher speed, larger pattern flexibility and the operating efficiency of Geng Gao.
The tradition multi-needle quilter has three-axis moving.X-axis be the band material of cloth during through the quilting station its motion vertically.Usually, this motion is two-way, and wherein the band material of cloth can be forward or counter motion, make to sew up to be achieved in any direction, for example, need to be on cloth quilting 360 degree patterns.The cloth integrator is followed this two-way machine usually, thereby can oppositely partly be with material, and needn't change along the quilting line direction of whole length band material.The band material also forms the Y-axis motion from a lateral movement to opposite side, also be used to form quilting pattern.Usually, it is static that quilting mechanism keeps in quilting technique, and control cloth motion simulation, thereby affect the quilting of various patterns.
X-axis and Y-axis are parallel to cloth quilting plane, and this is horizontal plane normally.The 3rd axle, Z axis, perpendicular to this cloth plane, the method for movement that moves back and forth pin that form to produce QUILTED STITCH to.Usually the eedle of the upper sewing head above the cloth plane, looper (looper) co-operating with cloth opposition side or downside, move back and forth perpendicular to Z axis, normally in X-direction.The suturing mechanism top that comprises the eedle driver, in traditional multi-needle quilter by the carrying of a large static bridge section.The suturing mechanism bottom that comprises the looper driver is contained on the cast iron platform.For example, three row can be installed on each corresponding upper and lower structure and sew up element.All pins all are connected to an independent main shaft and by its driving.
Traditional multi-needle quilter is used single large pressure foot, by the band material Partial shrinkage of all clothes of suture zone on band material width.In a kind of typical machine used in mattress industry, this pressure foot can be in each stitching process, and size is surpassed to the cloth area of 800 square inches, and to be compressed to thickness little of 1/4 inch.When after each stitching forms, from cloth, extracting pin out, pressure foot must still be reduced to cloth presser approximately 7/16 inch.Because cloth must form pattern with respect to sewing up the element motion in still below pressure foot, so pattern is parallel to the dilatory force distortion of cloth plane effect on cloth usually.These conventional machines weigh greatly, and occupy the suitable large tracts of land of mattress manufacture factory site face.
In addition, multi-needle quilter lacks flexibility.Most of machines provide the locking pin of straight line or an array, and these operate simultaneously, sew up identical pattern and the stitching of same train.Changing pattern needs the physics setting, rearranges or dismantles pin, and the pin threading that change is arranged.This reconfiguring between the waste working hour, machine stopping time is long.
Conventional chain-type stitch machine for quilting uses the shaft-driven crank mechanism of rotation, makes one or more pin through thick multilayer cloth.The active force of drive motors, and the inertia of connecting rod, force eedle to pass cloth.The eedle so produced the normally sine curve that moves, is that the curve meaned by equation y=sin (x) forms.For this application, the motion that does not meet the party's journey is called non-sinusoidal cuve.Therefore, the motion of eedle makes the eedle point from high position, and for example cloth top is 1 inch, is passed down through and is compressed to the roughly cloth of 1/4 inch, arrives below cloth the approximately position of 1/2 inch, in its reversing of motion in addition.Eedle carries upper thread through cloth, and forms ring in the looper side of cloth, by looper thread, is picked up.In the looper side of cloth, looper or bearded needle rotatablely move and move back and forth by sine curve around an axle.Looper enters with respect to the ，Shi Qi tip, position of eedle the upper thread ring that eedle forms, and in the looper side of cloth, the looper wire loop is passed to the upper thread ring.The motion of looper and the synchronized movement of pin, thus when eedle during the downward process in its cycle period, the upper thread ring is picked up by looper thread.Then, eedle rises and extracts out from cloth, stays upper thread and walks around looper and looper wire loop.
When from cloth, extracting pin out, cloth moves with respect to sewing up element, and eedle descends again through cloth, and dropping distance equals a stitch length of the previous pin crossing point of distance, thereby forms a stitching.When again when the cloth, eedle forms next upper thread ring ring through looper thread, the latter is that looper passes previous upper thread ring and before stings out.In this moment of cycle period, looper itself is extracted out from the upper thread ring, in its sine curve, moves back and forth, and stays the looper wire loop around the stitching auxiliary member, be called stop (retainer) in a lot of machines, for eedle decline next time keeps the looper wire loop open.In this process, along with the looper wire loop alternately forms and pass the upper thread ring, the upper thread ring forms and passes the looper wire loop, thereby forms the chain link replaced along cloth looper side eedle and looper thread, and it is visible only staying in cloth eedle side a series of stitchings that formed by upper thread.
In chain-type stitch formation machine, through experience for many years, can regulate the conventional sinusoidal motion of eedle and looper, keep reliable line to get ring, thereby can not miss stitching in the sewing process.In express stitcher, the motion of eedle makes needle point below the cloth plane, or supports below the needle plate of cloth, continues approximately 1/3 eedle cycle period, or 120 degree of eedle cycle period.
Through in the part eedle cycle period of cloth, preferably there is no the cloth motion simulation with respect to eedle at eedle.The inertia of machine element and cloth causes cloth to occur with respect to motion between some stitchings of eedle, and now eedle is through cloth.This causes the eedle deflection, and will cause and miss stitching, because looper misses the upper thread ring or eedle misses the looper wire loop, or because cloth stretches and distortion causes the loss of pattern definition.In addition, the restriction eedle is the speed through fabric through the time qualified eedle of fabric, and this has determined the ability of eedle through thick multilayer cloth.And, increasing eedle speed and need to increase the eedle travel distance, thereby cause upper thread too much below fabric loose, this must pull-up in the stitching forming process, makes stitching become tight.Therefore, to chain-type stitch, sewing has limitation in conventional eedle motion, particularly to the high speed quilting.
And the curved needle head in known multi-needle quilter produces the looper motion by driving cam follower on cam surface, this need to lubricate and form the wear-out part that needs maintenance.
In addition, the chain-type stitch that multi-needle quilter is used forms part, and each comprises the eedle moved back and forth through cloth from facing one side usually, and looper or bearded needle, looper is by the puncture needle top line ring that one side forms at the cloth back side, along the route vibration of the cloth back side one side.The chain type sewing comprises, by the eedle of the cloth back side one side and the interaction of looper, forms the alternately interlocking of a series of or chain type in the cloth back side one side between top line and bottom line, forms a uniserial top line stitching in the cloth top side simultaneously.Form reliably serial stitching and need to accurately set up eedle and the looper route that each sews up the element group, thereby eedle and looper can not miss the ring that picks up contrary line.Miss this ring and produce wrong stitching, this is the defect of sewing pattern.
Using the initial of quilting machines and periodically, must regulate the relative position of eedle and looper.Usually, this comprises the lateral adjustments of looper in the position of its vibration axis.In multi-needle quilter, this adjusting is to make the route of looper next-door neighbour eedle side, through directly over the eedle eye of top line.In this position, the upper thread ring forms on the eedle side, thus the looper point is inserted to the bottom line ring.The formation of these rings and interlocking chain-type stitch at length is disclosed in U.S. Patent No. 5154130, and this patent is by reference in conjunction with in this application.
Looper is regulated normally manual processes.Adjusting is undertaken by the technical staff when machine stops, wherein use the hand tools of some types to unclamp, reorientate, verification and tighten looper, thereby when eedle is near the eedle by the quilting fabric bottom side carries out the route nadir, looper, near eedle or lean against gently on eedle, is regulated certain operating personnel's time that takies.In multi-needle quilter, the quantity of pin can be a lot, and the adjusting time is long.Usually, the quilting line will only be regulated and stop nearly 1 hour or the longer time for eedle.
And regulating due to looper is manual process, is difficult to touch regulating element, is difficult to determine looper and eedle relative position, and is difficult to regulating element is remained on its position, simultaneously using the fixing or locking member of assembly as regulating error source.
Usually each comprises from facing one side back and forth through the eedle of cloth multi-needle quilter chain-type stitch forming element used, and looper or bearded needle, and looper is by the puncture needle top line ring that one side forms at the cloth back side, along the route vibration of the cloth back side one side.The chain type sewing comprises, by the eedle of the cloth back side one side and the interaction of looper, forms the alternately interlocking of a series of or chain type in the cloth back side one side between top line and bottom line, forms a uniserial top line stitching in the cloth top side simultaneously.Top line or upper thread from the fabric top side or facing one side through fabric, in the fabric bottom side or the back side one side form ring.Bottom line is only to remain in envers one side, forms an alternately chain of interlocked rings with the top line ring herein.
The high speed multi-needle quilter, those that use in External cover of bed-mattress is manufactured such as those, usually according to the pattern part sewing pattern of discontinuous series.Form noose stitching (tack stitch) in this sewing, and, when quilting pattern partly finishes, at least cut off top line.Then, fabric advances to new pattern part with respect to eedle and starts place, forms herein more noose stitching, and restarts sewing.A kind of high speed multi-needle quilter like this is referring to U.S. Patent No. 5154130 recited above.This patent is described a kind of method of cutting off line in this multi-needle quilter especially in detail.Therefore, need more reliable and more effectively line management in multi-needle quilter.
These characteristics and the requirement of high speed multi-needle quilter, and above-mentioned deficiency, the carrying out that has stoped traditional quilting machines more speed and larger pattern flexibility.Therefore, need to overcome these obstacles and increase quilting process operation efficiency, particularly the large volume quilting used for the bedding industry.

And in accordance with the embodiments illustrated, but the self-movement bridge section of carrying eedle and looper sewing mechanism has two axle movement, is respectively X1, Y1 and X2, Y2.Y-axis motion makes the motion of corresponding bridge section from a side to opposite side, is parallel to band and expects and cross its extension and the direction of motion; And X-axis motion makes the upper and lower motion of bridge section, be parallel to band and expect and be parallel to its direction of motion.In another embodiment, provide the bidirectional-movement of band material, the unnecessary X-axis motion that bridge section is provided.The X of bridge section, Y motion is by separating of each bridge section, controlled X and Y driver formed.Preferably, the motion of the Y-axis of bridge section has the scope of 18 inches, 9 inches in each direction of each side of center, and no matter is that band is expected or bridge section moves along directions X, and bridge section has 36 inches scopes with respect to the X-axis motion of band material.
According to some principle of the present invention, quilting machines has one or more quilting heads, can be at horizontal or vertical directional control eedle.According to other aspects of the invention, sewing head in a kind of machine is provided, can operate separately or one or more other this sewing head combination operation, in identical or different direction, perhaps identical or different speed or stitching speed (stitch rate), by same movement, be synchronized with the movement or independently moving, the identical or different pattern of sewing.
The quilting machines of some principle preferred embodiment according to the present invention, the sewing head that can be bundled together in static platform or motion bridge section is provided, and can arrange with one or more other sewing heads, thereby be bound together into separately and independent group in another platform or bridge section, with other combination operation or separately and separate control.
In illustrated embodiment of the present invention, bridge section separates with independent support and moves, and each bridge section upper support is several separates and the independent sewing heads that operate.Each bridge section can separate and independent control and motion, can move with respect to the quilting fabric flat transverse with vertically.Bridge section is contained on the common support leg, and supporting leg is separated near by the quilting fabric route, vertically extends, and makes the common linear bearing sliding system guiding of bridge section in being combined in each supporting leg.Each leg also carries a plurality of counterweights, one, each bridge section.The controlled servomotor of different independence drives each bridge section along vertical and level-horizontal direction.The motor of each bridge section produces the vertical and horizontal movement of bridge section.
In addition, according to some aspect of the present invention, each bridge section has independent controlled driver, makes to sew up element, eedle and looper and moves back and forth.Driver is the most practical is the rotation input, as from rotating shaft, operating element move back and forth connecting rod.The independent operation of the driver of each bridge section makes sewing head or sewing head group carry out independent sewing operation, or one or more free time and one or more other head sewing.Every stature has the element that response controller is controlled, and preferably response is sent to the data signal of all heads on common bus, and each controlled member has the decoding circuit of selecting for the bus signals of respective element.
In illustrated embodiment of the present invention, each sewing head, comprise each needle head and each curved needle head, be connected to public rotating driver by independent controlled clutch, clutch is handled by machine controller, head is opened or closed, thereby the pattern flexibility is provided.In addition, head can be arranged to sew up element pair, and each needle head has corresponding similar module curved needle head.Although every enemy can open and close separately, they open and close together usually, or simultaneously or, in the out of phase of its cycle period, this may wish most.In addition, only needle head can have the selection drive link, and curved needle head can be connected to the output of eedle drive motors, thus operation continuously.This connecting rod can be directly and permanent, but or can be adjustable switch or can be with respect to eedle driver phase modulation position, for example, by different driving mechanism is provided in the looper drivetrain.When using directly driving, the curved needle head driver is connected to input drive shaft by gear-box rather than clutch.Each curved needle head also has the alignment disk on the curved needle head driving shaft, when curved needle head is contained in machine, the phase place of each curved needle head with respect to other curved needle head or eedle driver can accurately be set.In addition, each curved needle head shell has two sizes in the plane perpendicular to eedle to be regulated, and while being convenient to curved needle head is installed, curved needle head is alignd with corresponding needle head.
In addition, according to other principle of the present invention, provide a plurality of presser feets, presser feet of an eedle of each needle head.This can reduce the cloth total amount that needs compression, reduces quilting machines and operates required power and active force.Each eedle, and corresponding looper, can move separately and control, or by than aggregate motion and the control of all that combined few in bridge section, and can selective actuation and stop.The startup of eedle and looper and stop being to provide, and preferably being realized by computer-controlled actuator, for example electronics, pneumatic, magnetic or other type actuator or motor or mobile connecting rod.
To sewing up element and the less gross pressure of pressure foot and the requirement of active force, allow quilting machines to there is the structure that weight is lighter, and in bed articles for use factory occupy than small size than small machine.In addition, use the independent presser feet presser feet of avoiding over to arrange a lot of pattern deformations that cause.Spacing between needle plate by fabric looper side and the rising presser feet of fabric eedle side is wider, can strengthen these advantages.This spacing can reach several inches.
According to other principle of the present invention, the eedle that chain-type stitch forms machine can be driven into the motion different from conventional sinusoidal motion.In illustrated embodiment of the present invention, drive a chain-type stitch to form the eedle of head, perhaps a plurality of chain-type stitchs form every eedle of head, thereby compare with the situation of conventional sine mechanism needle movement, in the major part of its cycle period in lifting position, and at the smaller portions puncture cloth of its cycle period.And according to the present invention illustrated embodiment, drive eedle, it is moved downward through cloth, move downward the movement velocity that velocity ratio extracts out from cloth fast.In another embodiment of the present invention, provide sinusoidal motion.
In the embodiment asymmetric, that the non-sine eedle moves, eedle decline is substantially equal to through the degree of depth of cloth the degree of depth that sinusoidal motion provides, but with conventional sinusoidal motion, compare, motion is very fast and arrive its stroke minimum point in the smaller portions of its cycle period.Yet eedle rises slower than its decline from its stroke minimum point, the time existed below cloth is at least the same with conventional sinusoidal motion long or longer, thereby looper has time enough to pick up the upper thread ring.As a result, eedle forms the cloth puncture force larger than prior art, and eedle deflection and cloth deformation ratio prior art are little, and this is shorter through the time of cloth mainly due to eedle.
According to the present invention, the quilting machines of some principle embodiment provides a kind of mechanical linkage, and wherein hinged lever or driver make the eedle motion depart from sine curve.A kind of cam also can provide the curve different from sine curve with the cam follower structure.Similarly connecting rod also can drive presser feet.

U.S. Patent application No.09/686041 has disclosed a kind of quilting machines this motion, that have the SERVO CONTROL quilting head that is suitable for implementing, and quotes as a reference here.Use this equipment, by the controller of sequencing, control the quilting head servomotor, thereby carry out sewing movement.For the present invention, director demon manipulation sewing head, drive eedle by motion described here.In another embodiment, the needle head of quilting machines has mechanical linkage, and design becomes eedle provides the non-sine motion, as mentioned above.The mechanism that carries out this motion can be formed by connecting rod and the element of asymmetric weight, its Mass Distribution departs from the asymmetric force that asymmetrical movement produces, and makes to be different from the vibration effect minimum that the disresonance of conventional harmonic sine function, irregular acceleration that the non-sine motion causes produce.In certain embodiments, itself has shell mechanism sewing head, while being contained in bridge section right overhead, for reinforcing, strengthen and sclerosis bridge section, makes vibration minimum.
In addition, according to principle of the present invention, curved needle head rotatablely moves input to convert two independently motions to, and the cam follower that need to not slide on cam.Therefore, curved needle head is adjustment of balance mechanism, there is the element of minimum number and do not need to lubricate, thus the maintenance needs minimum.Similarly, the structure of needle head does not need to lubricate yet.
According to other principle of the present invention, the looper adjustment feature is provided, for the looper of regulating chain stitch quilter-eedle relation, particularly on multineedle sewing machine, use.Adjustment feature comprise there is regulating element easily touch the looper retainer, make thus the looper point towards the eedle motion and away from eedle.In one embodiment, single two-way adjustable bolt or other element make the looper point move in either direction.Locking element also preferably provides separately.In order to regulate looper, controller makes to sew up element and advances to and pick up constantly adjusting position of ring, and now they stop and entering the safety lock pattern, for regulating looper.Then, when regulating end, element is sewed up in the controller reversion, thereby does not form stitching in cloth.
According to a further aspect of the present invention, provide eedle-looper proximity transducer, this sensor is connected to indicator, and its signal is to sew up the position of the looper of element group with respect to eedle, is shown to the operator who regulates looper.Preferably, the luminous indication looper of coloud coding lamp is with respect to the position of eedle, and wherein a kind of indication is to arrange when correct, and one or more indications are to arrange when incorrect.Incorrect indication can comprise that looper is disembarked pin too closely or a kind of coloud coding lamp when too far away luminous, and another indication is that looper is when other direction is too far away.
In illustrated embodiment of the present invention, the looper retainer has palp governor motion, and the operator moves a direction in office with an independent adjusting and regulates the lateral attitude of looper with respect to eedle thus.This mechanism comprises the looper retainer, and wherein the looper element is contained on pivot, with respect to the eedle of sewing mechanism at lateral bearing looper point.Regulating looper point position is by a direction or another direction, rotating independent adjusting bolt, makes the looper point with respect to the eedle side-to-side movement.Looper is biased in the adjusting bolt end at its retainer medi-spring, thus when bolt when direction is rotated, spring is yielded to the bolt active force; When bolt, when other direction rotates, spring rotates looper towards bolt.Adjusting bolt and spring are clamped in it by looper and regulate rear position, and can tighten the lock bolt be contained on retainer, looper is clamped in to it and regulates rear position.
The other feature according to the present invention, provide and detect the sensor of looper with respect to the eedle position, and this can be to detect the circuit form contacted between looper and eedle.Indicator lamp can be provided, for example, the operator that notice is carried out the looper adjusting when eedle contact looper, thus can accurately consider contact formation/braking point when regulating.Sensor can be also some other looper and/or eedle position monitoring device.
According to principle of the present invention, multi-needle quilter has single wire cutter in each eedle position.Wire cutter is preferably located on each curved needle head of spininess chain sitch sewing machine, and each device can operate separately.In a preferred embodiment, each curved needle head of multi-needle quilter has wire cutter, and wire cutter has movable blade or set of blades, cuts off at least top line under the order of machine controller.Device also preferably cuts off bottom line, and, when carrying out this process, preferably clamps bottom line or looper thread, until sew, proceeds, normally at the reposition by quilted fabric.When but quilting machines has individually actuating or separately controllable sewing head, can single installation or removal the time, looper of each this head partly has separately controllable wire cutter.
In order to reduce to miss the possibility of stitching, can use initiatively or the guiding of passive looper thread tail, when starting, below needle plate, handle or otherwise guiding looper thread tail.In certain embodiments, provide looper thread deflector guiding looper thread, thereby eedle can not miss the looper thread triangle.In addition, when particularly pattern starts after cutting off looper thread, provide a kind of control method that starts to separate, miss a kind of feature of selecting of stitching when avoiding starting.Starting separation characteristic is to make eedle separate and distinguish a kind of application of motion characteristics with the looper driver.Use and start partition method, the initial motion of eedle and looper driver carries out respectively when starting, thereby stitching is picked up, can predict.This guarantees that by picking up at eedle before bottom line ring triangle looper picks up top line and realize, this is a kind of a kind of method that alternative approach is provided starting partition method, and for example looper thread is handled.This is assist by a pair of eedle guiding of each looper drive location, and this guides one on looper to eedle, one on curved needle shell, the two is all adjustable.The guiding of two-shipper pin has limited the eedle deflection perpendicular to the looper plane of movement, increases thus the reliability that stitching forms.
Another kind of scheme is that cut-outs top line is scraped to the cloth top, comprises that line scraper mechanism and the motion of bridge section strike off the cycle, before a new pattern part starts, it is cut off after from cloth removal cut-out top line.In addition, provide line the pleating cycle, will cut off the top line tail and be placed in the cloth back side when starting the sewing pattern curve.The pleating cycle is missed the possibility of stitching while also reducing to start.Strike off and the pleating cycle can be combined into noose between pattern, cuts off the part of line, hand pick (jump), noose and beginning sequence.
A kind of noose stitching sequence (tack-stitch sequence) lockstitch also is provided, makes the minimum possibility that also further reduces to miss stitching of eedle deflection, this is particularly useful when starting the noose sequence.This sequence is included in pattern direction sewing certain distance, for example about one inch, is then starting to turn back to home position along same straight line before normal pattern sewing along sewing thread.In this sequence, use long stitching to sew up element in conjunction with being interrupted with respect to cloth to carry.This is interrupted bull ladle and draws together the another kind of cycle period of eedle through cloth, and with respect to eedle, does not carry cloth, then suspends the eedle cycle period, extracts eedle from cloth out, and cloth moves with respect to eedle simultaneously.It is indispensable that cloth or eedle stop not being, but can be at other eedle or cloth motion simulation of slowing down more reposefully that move.The reverse directions in pattern of no matter when sewing, particularly when the sewing that oppositely causes use when in pattern, the previous stitching formed had returned, can use this stitching sequence.This is particularly useful in starting the noose process, and can or cannot be applied to finish noose.In the sewing process, preferably use continuously and carry, rather than be interrupted and carry.While for the position at previous cut-out line, starting sewing pattern, from being interrupted, carry the stitching sequence to be transitioned into continuous conveying stitching, use a series of interruptions-continuous transition stitching.
And, according to the principle of the invention, every line of quilting machines or other Sewing machines has the line tension monitoring device.The line tension control device of every this line can change it automatically to be regulated, thereby regulates the tension force of line in response to monitoring result.Preferably, to every line of machine, provide closed loop feedback to control.During each device operation, the tension force of independent measurement line is also proofreaied and correct tension force by the root line.
The bridge section drive system provided makes bridge section independently moving and control, and accurate and rapidly travelling bridge section, keeps its direction in abandoned situation.This feature for carrying out novel bind, can start separately and stop bridge section by the method for synchronization thus, thus alignment pattern and avoid between pattern wasting cloth.In addition, eedle that can be by different bridge section is at the noose stitching of not sewing in the same time.
The independent controlled motion of difference bridge section and different motion degree provide the ability of manufacture wide region pattern and the larger flexibility of selection and manufacture pattern.Can manufacture unique quilting pattern, for example, the different pattern that those different eedles or eedle combination are manufactured.For example, can move different bridge sections at the different pattern of sewing in the same time mutually.
Feature of the present invention provides a lot of new patterns and pattern stitching process.Some of them are at least parts as the feature of equipment obtains in accordance with the principles of the present invention result.Below detailed description in, provide some special applications in connection with the discussion of accompanying drawing and equipment operating.
This mechanism has low inertia than traditional quilting machines.Quilting speed has been increased to 1/3, for example, reached 2000 pins per minute.
To sewing up element and the less gross pressure of pressure foot and the requirement of active force, allow quilting machines to there is the structure that weight is lighter, and in bed articles for use factory occupy than small size than small machine.In addition, use the independent presser feet presser feet of avoiding over to arrange a lot of pattern deformations that cause.
In addition, do not need quilting fabric is moved by side to opposite side and need under large pressure foot, not push cloth from one, make machine there is simple cloth route, thereby make machine dimensions less, be more suitable for automatic distributing processing.

The curve 700,710 of Fig. 2 B means quilting machines sewing head tip positions, is with the upper/lower positions of distance pin or the inch number of down position and period position leave the function representation of the number of degrees that the cycle starts fully.Cycle starts to be defined as minimum pin position 180 degree before and 0 degree position of curve.
Curve 700 is symmetrical sine curves 700 of standard, represents the needle movement of prior art sewing head, for example in the described quilting machines of U.S. Patent No. 5154130, occurs.This pure sinusoidal motion is to be produced by the other sewing head assembly embodiment shown in Fig. 2 C, and this will be described in greater detail below.This curve 700 has extreme lower position 701 at 180 degree, and definition pin height is 0.0 inch, here with for referencial use planting (attention, " pin height " is according to tradition actual measurement in the horizontal direction, the pin side usually is called cloth " top " side thus, or even cloth 12 is in end face 16).Curve 700 has the eedle position 702 of pushing up most at 0 degree and 360 degree in cycle, and now eedle is elevated to the some height of 1.875 inches more than 701 planes.From descending most approximately 0.5 inch of eedle position 701, eedle is through being placed on for example plate 38 of needle plate plane 704() on the zone 803 that occupies of one deck fabric thickness, for example cloth 12.Under the compression of presser feet, for example presser feet 158, the finish coat of the cloth 12 that zone 703 and plane 704 are separated, and distance is descended the approximately height of 0.75 inch of eedle position 701 most.As a result, eedle, in point 705 drops to area of cloth 703, is entering slightly spending over 100 of cycle; And rose from cloth before just entering about 260 degree in cycle, stay eedle at least partially in spending through about 159 of the cycle in cloth, this depends on fabric thickness.Under this motion, the eedle point from about 116 degree in cycle to about 244 degree below needle plate, or spend the cycle at about 128 of sine curve 700.
The second half period of curve 710 and the first half asymmetric, in last 180 degree in cycle, eedle rises along the curve identical with sine curve 700 from upper/lower positions 700.As a result, the eedle of curve 710 is only about 116 degree in cloth district 703, from about 140 degree in cycle, to about 256, spends.The eedle of curve 710 from the cycle about 144 the degree to about 240 the degree below needle plate, or 710 cycles of curve about 96 the degree.
With curve 700, compare, the eedle with curve 710 actions passes quickly cloth in about 4 degree in cycle, and curve 700 is about 15 degree in cycle; Remaining on the shorter time of area of cloth 703, be 116 degree, and curve 700 is 159 degree; The time that has roughly the same length for the looper below needle plate, curve 710 is 60 degree, and curve 700 is about 64 degree.Therefore, the feature of eedle point action is non-type asymmetric sine curve or non-sine motion.
The point motion of the pin 132 of curve 710 representatives is what by hinged eedle driver 110, to be formed.Pin 132 rest on through speed, eedle the speed that time length in cloth and pin exit cloth, be the determining positions of relative length and pivot pin 117 by the diameter of crank 106, connecting rod 114,116 and 120 pivoting point that forms with respect to pivot pin 121.These provide the variable numerical value of eedle required reciprocating action in time, can carry out mathematical computations by computer model or experience and determine.It should be noted, curve 710 is only to use hinged eedle driver 110 how to drive an example of eedle.Different application may need the different pattern of eedle reciprocating action in time, and the diameter of crank 106, connecting rod 114,116 and 120 and the position of pivot pin 117 can suitably revise, thereby required eedle reciprocating action pattern is provided.
The curve 714 of Fig. 2 B means the action of a point on presser feet 158.The absolute position of presser feet 158 also be can't help offset axis and is meaned, but curve 714 has meaned the relative position of presser feet 158 with respect to eedle 132 effectively.Presser feet 158 from about 140 degree in cycle to about 80 degree of about 220 degree in its upper/lower positions.And it is quicker than its release cloth that moves upward that presser feet 158 moves downward the compression cloth.Wish that through before cloth cloth is fully compressed and stablizes at eedle 132.In addition, presser feet 158 is extracted out slower, the motion minimum of cloth when eedle 132 is extracted out from cloth.When carrying out eedle curve movement 710, presser feet curve movement 714 is non-sinusoidal cuve or motion.
The motion of a point on the presser feet 158 of curve 710 representatives is to be formed by hinged presser foot driver 144.The time length of presser feet 158 fall off rates, presser feet compression cloth and the speed that presser feet 158 rises from cloth are by the relative length of the diameter of crank 140, connecting rod 146,150,152 and pivotally connected determining positions that pivot pin 151 forms with respect to pivot pin 153.These provide the variable numerical value of presser feet required reciprocating action in time, can carry out mathematical computations by computer model or experience and determine.It should be noted, curve 714 is only to use hinged presser foot driver 144 how to drive an example of presser feet 158.Different application may need the different pattern of presser feet reciprocating action in time, and the diameter of crank 106, connecting rod 114,116 and 120 and the position of pivot pin 151 can suitably revise, thereby required presser feet reciprocating action pattern is provided.
Referring to Fig. 3, output belt pulley 166 is fixed on output shaft 168, and output shaft 168 is contained in by bearing 178 that shell 170 is interior can be rotated.Actuator 176 is fixed on eedle driving shaft 32, and is contained in by bearing 178 that shell 170 is interior can be rotated.Actuator 176 has the first semicircle flange or flange 180 radially extended, and along the direction that is basically parallel to center line 184, extends, and the drive surfaces of aliging on a pair of diameter is provided, and one of them is illustrated in 182.Drive surfaces 182 is basically parallel to the longitudinal centre line 184 of eedle driving shaft 32.
Sliding part 186 has the first semicircle flange or flange 188, and along the direction that is basically parallel to center line 184 towards annular flange, 182 extend.Flange 188 has the drive surface of aliging on a pair of diameter, and one of them is illustrated in 190, can insert the drive surface 182 of relative flange 180 and from wherein extracting out.Sliding part 186 passes through actuator 192 with respect to output shaft 168 translations.Actuator 192 has annular piston 194, is contained in the interior slip of ring cavity 196 of shell 100, thereby forms the fluid chamber 198,200 adjacent with piston 194 opposite ends.Annular seal ring 202 is for forming Fluid Sealing between the wall in piston 194 and fluid chamber 198,200.Sliding part 186 can rotate by bearing 204 with respect to the installation of piston 194.
When operation, eedle driving shaft 32 stops at required angular orientation, and, by pressure fluid, for example forced air, be incorporated into fluid chamber 198.From Fig. 3, piston 194 from the left movement to the right side, thereby make drive surface 190 motion of sliding part 186 relative with drive surface 182, as shown in Figure 3A.Clutch 100 with engagement like this, eedle driving shaft 32 direct mechanical are connected to sliding part 186 and output shaft 168, and output belt pulley 166 is followed the rotation of eedle driving shaft 32 exactly.The rotation subsequently of eedle driving shaft 32 causes output shaft 168 to rotate simultaneously.
When eedle driving shaft 32 is parked in required angular orientation again, from fluid chamber's 198 releasing pressurized fluids and be applied to fluid chamber 200.From Fig. 3, piston 194 moves to a left side from the right side, thereby makes the contact separation of drive surface 190 motions and drive surface 182, and throws off with clutch 100.Like this, drive surface 182 rotations are crossed and are driven flange 188, and 32 rotations of eedle driving shaft, independent irrelevant with output shaft 168.
But, in disengaged condition, need to when clutch 100 separates, make output shaft 168 remain on fixing angle position.Like this, sliding part 186 has the second semicircular ring lock flange 206, from Fig. 3, along the direction that is basically parallel to center line 184, extends to left side.Alignment lock face 205 on the lock flange diameter.In addition, semicircle lock flange 208(Fig. 3 B) be contained on the radial wall 210 of shell 170.Alignment lock face 207 on lock flange 208 diameters.Like this, when eedle driving shaft 32 is parked in required angular orientation, because piston 194 moves to a left side from the right side, with clutch 100, separate, as shown in Figure 3, the lock face 205 of lock flange 206 moves to the position that lock flange 208 is close to lock face 207, as shown in Figure 3 B.Like this, when eedle driving shaft 32 stops, cylinder body 192 operations make clutch 100 engagements and separate, that is, make power shaft 32 mesh and separate with output belt pulley 166, in order to optionally handle a sewing head 25.In addition, when clutch 100 separates, output belt pulley 166 remains on required fixed angle position, thereby pin 132 and presser feet 158 remain on required angle position separately, wait for the operation subsequently of clutch 100.

Final result is, wig-wag shell 240 is crooked or tilts, and makes an end 276 than the contrary other end 278 more outwards or more close needle plate 38.In other words, in the position of the eccentric shaft 250 shown in Fig. 4 B, eccentric shaft outer end 253 is positioned at below rotating shaft 270, and eccentric shaft the inner 251 is positioned at above rotating shaft 270.And on the first circumferential point 272 diameter groups of wig-wag shell 240 cross sections, contrary second point 274 more outwards or more close needle plate 38.When eccentric shaft 250 rotates 180 degree from its illustrated position with respect to its center line 271, eccentric shaft outer end 253 is positioned at rotating shaft 270 tops, and eccentric shaft the inner is positioned at rotating shaft 270 belows.Like this, the second point 274 of wig-wag shell 240 is outwards towards moving near needle plate 38, and the 1: 272 inwardly motion.When the further rotation 180 of eccentric shaft 250 is spent, wig-wag shell 240 and wig-wag main body 242 are returned to its position shown in Fig. 4 B.Therefore, eccentric shaft 250 further fully rotation cause a little 272,274 continuously towards needle plate 38 translations and leave needle plate 38, pass through the displacement shown in arrow 280.Like this, the continuous rotation of eccentric shaft 250 makes wig-wag shell 242 swing or wave with respect to rotating shaft 232.Referring to Fig. 4 A, angular oscillatory motion is delivered to curved needle shaft 218, thereby makes looper flange 220, looper retainer 214 and the reciprocal angular movement of looper 216 experience.
Referring to Fig. 4 A, stop cam 258 is connected to outer wig-wag gear 256, makes it also with respect to rotating shaft 270 rotations.Stop cam 258 has the crank 260 that radially departs from rotating shaft 270.The near-end of stop actuating arm 262 is contained on crank 260 and can rotates, and stop 234 is contained in the far-end of stop actuating arm 262.Stop actuating arm 262 slides after installing in the hole 264 of back-up block 266.Back-up block 266 hingedly is contained in end face 268(Fig. 4 of looper drive enclosure 238).Therefore, power shaft 226 and outer stop cam 258 often turn a full circle and will cause stop 234 around needle shaft along a closed-loop or orbital motion, thereby form the required knot of chain-type stitch.The feature of stop route is with respect to the determining positions of crank 260 by the length of actuating arm 262 and back-up block 266.
Looper and stop driver 212 are a kind of fairly simple mechanisms that rotatablely moving of power shaft 226 converted to two self-movements of looper 216 and stop 234.The unfavorable cam-follower slided on cam that is used in of looper and stop driver 212, therefore do not need to lubricate.Reduced thus the maintenance demand.Looper and stop driver 212 are high speed and the balanced controls that use the minimum number element, for moving back and forth of looper 116 and stop 234 is provided.Therefore, looper provides reliable and effective looper function together with corresponding eedle driver with stop driver 212.
Fig. 4 means a kind of looper driven unit 26 of multi-needle quilter 10, and wherein pin is horizontal alignment.Looper driven unit 26 can comprise selects connector 210, and for example, clutch 210, can be connected to the drive train of synchronizeing with the driving of crew-served eedle driven unit by the input of driven unit 226 209.Looper driven unit 26 comprises framework 219, the mode top loading of driven unit 226 and 210 mutually to align.Framework 219 is contained in the rear portion 24 of corresponding bridge section 21,22, makes the corresponding needle head assembly 25 of curved needle head assembly 26 alignment.The output of clutch 210 drives the looper drive 212 with output shaft 218, and output shaft 218 has flange 220, and looper retainer 214 is installed on flange 220.In the multi-needle quilter of other type, this looper retainer 214 is waved by the common driver connecting rod of the drive train that for good and all is connected to the eedle driver, can together with other looper, around a common axis, swing, as described in U.S. Patent No. 5154130.Chain-type stitch forms the character of machine and the quantity of pin is not the essence of concept of the present invention.
Usually, looper 216, when being installed on looper retainer 214, swings along route 800 on axle 218, forms collaborative stitching with eedle 132 and forms relation, as shown in Figure 4 C.Stitching to eedle and looper forms more thoroughly describing referring to U.S. Patent No. 5154130 of relation and motion.In the stitching forming process, looper point 801 enters the ring 803 of the top line 222 that eedle 132 provides.In order to pick up this ring 803, the lateral attitude of the point 801 of looper 216 remains on adjustment state, makes it be close to eedle 132 processes.The adjusting of looper 216 is to realize with the axle 218 that is parked in its wobble cycle, makes looper point 801 lateral alignment pins 132, as shown in Figure 4 C.In this adjusting, point 801 transverse shiftings of looper 216, that is, and perpendicular to pin 132 and perpendicular to the route 800 of looper 216.
As shown in Fig. 4 C and 4D, the preferred embodiment of looper 216 is made by the entity stainless steel part, has hook portion 804 and base part 805.Far-end at hook portion 804 is looper point 801.Base part 805 is pieces that hook portion 804 stretches out from its top.Base part 805 has from its erection column 806 of stretching out of bottom, and looper 216 is contained in the hole 807 of retainer 214 and can rotates thus.
Adjusting is that the Allen bolt 812 in being screwed in retainer 214 is realized, thereby at the point 813 that departs from post 806, clings on the pedestal 805 of looper 216.Compress Spring 814 supports looper pedestal 805 at the point contrary with bolt 812 815, thereby 812 points 801 that will make looper 216 that tight a bolt will make the point 801 of looper 216 towards leaving eedle 132 motions towards eedle 132 motions and unclamp bolt 812.Lock bolt 816 for looper 216 being locked in to its adjusting position at retainer 214, and unclamp looper 216 and regulated.Lock bolt 816 is clipped in post 806 in hole 807 effectively, keeps it not rotate.
In fact, preferably regulate the position of looper 216, make point 801 or contact pin 132 just, or minimally leaves eedle 132.For the ease of reaching this position, a kind of electronics indicating circuit 820 is provided, schematically show in Fig. 4 F.Circuit 820 comprises the looper 216 be contained in retainer 214, and retainer 214 is contained on the flange 220 of axle 218, as shown in Figure 4 D by electrical insulator 821.Retainer 214 is electrically connected to LED or some other visual detectors 822, and indicator 822 is connected between retainer 214 and power supply or electric signal source 823, and power supply or signal source 823 are connected to the earthing potential of frame 11.Eedle 132 also is connected to earthing potential.Like this, when looper 216 contact pin 132, through the closing of circuit of indicator 822 and power supply or signal source 823, activate indicator 822.
The operator can regulate looper 216 by front and back adjusting bolt 812, thereby forms the contact point just separated between eedle 132 and looper 216.Then, the operator makes looper as required in this position or unidirectional retreating arranges or other, then by tighting a bolt, 816 looper 216 is locked on its position.
When carrying out the looper adjusting, quilting machines 10 stops, and makes pin in 0 degree or dieback dot center position, controller 19 makes to sew thus, and element advances to the cycle gets ring (Fig. 4 C) constantly, now element stops, and machine enters the safety lock pattern, makes the operator carry out the looper adjusting.After eedle and looper setting, under operator's input, the controller 19 of quilting machines 10 makes looper and eedle move along forming stitching direction direction in addition.This is to drive servo-drive system 67 and 69 by reverse drive pin and looper, makes eedle driving shaft 32 and looper driver 37 toward back rotation, and looper and eedle are retreated in its cycle, thereby makes eedle return to its 0 degree position.This stop to form stitching, and this is to wish to occur because looper regulate be usually between these patterns, complete best.By stoping stitching to form, whether looper is regulated any position of trace along the line and is completed, and no matter need to continue along straight line or route sewing.And, retained by the looper thread of pruning and the condition of top line in described trim lines condition of wiping off, as the description below with reference to Fig. 5-5D.
Single needle sewing machine is used multiple thread cutting device.The device shown in Fig. 5 850 for example.It comprises and moves back and forth linear-motion actuator 851, and this can be pneumatic.Double hook cutting knife 852 slides after installing on actuator 851, when it starts towards actuator 851 pulled straight.Actuator 851 is arranged on that on sliding shoe 858, (Fig. 5 is not shown, be illustrated in Fig. 2 C embodiment), make actuator 851 and associated component towards the motion of the pin hole of needle plate 38 and leave pin hole, its position occupied get back to the resting position that does not stop looper 216 when moving to cutter sweep and starting.Cutter 852 has upper thread hook 854 and looper thread hook 853, and each is hooked in when actuator 851 starts hooks corresponding top and bottom line.Hook 853 and 854 all has cutting edge, utilizes these swords to cut off line separately.Static overcoat 855 is fixed on actuator 851, has the surface that is designed to cut off with cutter 852 co-operatings of sliding line.When carrying out, cutter 852 is parked in retracted position, and the upper thread tail is unclamped, but keeps the bottom line tail to be clipped in cutter 852 and be fixed between the elastic metallic folder 856 of overcoat 855 bottoms.This folder prevents that looper from going offline, can be near cutting position, and make thus the looper thread tail can be very short.Fig. 5-5D means in machine to have the assembly perpendicular to the orientation pin.But in quilting machines 10, pin 132 horizontal alignments, perpendicular to vertical cloth charge level 16, and the orientation of looper 216 is along 16 swings in plane of horizontal horizontal direction parallel, the point 801 of looper 216 points to the left side (from the place ahead of Fig. 1) of quilting machiness 10.
Fig. 5 A means a kind of looper driven unit 26 of multi-needle quilter 10, and wherein pin is horizontal alignment.When the stitching chain sewing that continues discrete pattern or pattern part finishes, pin 132 and looper 216 are parked in the position shown in Fig. 5 A usually, wherein pin 132 is extracted this moment in the sewing cycle, upper thread 222 and the looper thread 224 looper side in the cloth 12 by quilting out at the pin hand hay cutter of the fabric 12 by quilting from cloth.Upper thread 222 extends around the looper hook 804 of looper 216 downwards and returns to fabric 12 from cloth 12, and looper thread 224 stretches out from line source 856, through looper hook 804, from the hole of looper 216 points 801 out, enters cloth 12.
Looper side at cloth 12, there is a cutter sweep 850 on each of a plurality of curved needle heads 26, each cutter sweep 850 has its actuator 851, and actuator 851 is equipped with pneumatic control line 857, is connected to the output of quilting machines controller 19 by suitable interface (not shown).Single thread-cutting device 850 itself is thread-cutting device used in the single needle sewing machine of prior art.
According to the present invention, in multi-needle quilter, by mode described here, use a plurality of devices 850.Referring to Fig. 5 and 5A, in each looper assembly 26 of spininess chain stitch quilter, install 850 position and be, when launching, install 850 cutter 852 between looper 216 and cloth 12, and connect into operation under the computer of the controller 19 of quilting machines is controlled.When in the cycle, cutting off the moment of line, as shown in Figure 5A, controller 19 starts actuator 851, makes the ring of cutter 852 through upper thread 222, thereby hooks pin and looper thread, as shown in Figure 5 B.Then, cutter 852 is retracted and cut off upper thread 222 and the looper thread 224 stretched out from cloth 12.Two cut end of upper thread 222 discharge, and extend to the cut end of cloth as looper thread 224.But the end that looper thread 224 extends to looper 216 still is jammed, as shown in Figure 5 C.This clamping keeps the looper thread end, thereby forms ring when continuing sewing, prevent that linear chain from starting the unexpected stitching quantity of front loss, and this will cause the defect of institute's sewing pattern.
Avoid losing the Additional Protection of stitching while starting as sewing, the orientation of looper makes, and when the end of looper thread 224 is not jammed, the end of line 224 is orientated a correct side of pin under Action of Gravity Field, thereby starts a series of stitching.By this way, form the probability encircled in the several stitchings of beginning that continue the sewing of noose stitching and beginning pattern high.
For having selective operating head or can installing separately and respectively, dismantle or be reset at the multi-needle quilter of the head of sewing in bridge section, the feature of above-mentioned trim lines is particularly useful.Each cutter sweep 850 has a curved needle head assembly and can together with each curved needle head assembly, dismantle, install and move.In addition, in the situation that head is selective operation, this feature makes each thread-cutting device controlled separately.
Prune feature for supplementary cords, line tail curette (wiper) 890 is housed on upper thread assembly 25.In addition as shown in Figure 5 C, curette 890 comprises that the line hook strikes off element 891, hingedly is contained near the pneumatic actuator 892 of eedle 132, after upper thread 221 cuts off, makes to strike off element 891 and rotates around the horizontal axis perpendicular to eedle 132.When starting, actuator 892 in presser feet bowl 158 inboards around the point of eedle 132 the inswept element 891 that strikes off, the line tail of upper thread 221 is dragged to the eedle side of cloth 12 and arrives presser feet bowl 158 inboards from cloth 12.From then on position starts, and when starting to sew, top line will can not be clipped under presser feet, thereby, when eedle descends for the first time when pattern starts, the line tail easily is rolled onto cloth 12 back sides usually.
Fig. 5 D means line tension control system 870, and it can, similarly for each root line of Sewing machines, be specially adapted to every independent line of above-mentioned multi-needle quilter.Line, for example looper thread 224, usually from line source 856, stretch out and pass thread tensioner 871, and it produces friction to line, thus the line that will move downstream is tensioned to looper 216.Device 871 is adjustable, for the tension force of control line 224.System 870 comprises line tension monitor 872, and line 224 extends between regulating wheel 871 and looper 216 through monitor 872.Monitor 872 comprises a pair of fixing wire carrier 873, the sensor 874 that line activated on arm 875 between the two laterally promotes and deflection, actuator arm 875 is supported on cross force converter 876, measures tensioned thread 224 and is applied to the cross force on sensor 874, produces the line tension measured value.Every line 222 and 224 has such line tension and controls.
Replace using line tail curette 890, as shown in Figure 5 C, or other mechanism that holds after cutting off and continue to cut off freely top line before the reposition sewing, can carry out the apparatus control sequence, reach the result that the line tail strikes off function.Fig. 5 E is illustrated in sewing pattern while partly finishing, before being cut off online, and top line 222 states after just execution set tie lines mark sequence.Illustrated top line 222 401 extends to the pinprick of eedle 132 through top line regulating wheels 402 from the top line source, this be can controller 19 output actuator 403 operations controlled.Between regulating wheel 402 and eedle 132, top line 222 is through pulling open mechanism 404, and it comprises the pusher 405 that actuator 406 drives, and actuator 406 is also to be controlled by the output of controller 19.In Fig. 5 E, the pusher 405 shown in solid line is in its retracted position.When actuator 406 starts, pusher 405 moves to the extended position 407 shown in its dotted line, and it is also the position shown in dotted line that top line is moved to.It is to be transmitted a signal to actuator 403 execution of top line regulating wheel 402 by controller 19 that top line pulls open, thereby discharges one section short time interval of tension force of top line 222, and line pulls open mechanism 404 and receives pulse during this period.The pulse that line pulls open mechanism 404 comes from the signal that controller 19 is dealt into the actuator 406 that pulls open mechanism 404, makes pusher 405 strut top line 222, thereby pulls open the loose top line of a segment length from top line source 401.In addition, make eedle 132 with respect to cloth 12 roughly one section short distance of several inches of motion, pull the relaxation length of top line through eedle 132, increase the line tail of certain-length between eedle 132 and cloth 12.This relative motion can be by front forward (FWD) material 12 or motion bridge section 21,22 or the two realization of all moving.
After pulling open as mentioned above top line 222, cut off line 222 and 224 and clamp looper thread, as described with reference to figure 5C.In this embodiment, still do not need to exist scraper mechanism 890.On the contrary, can utilize and strike off action.In this moment of operation, the top line tail is passed down through cloth 12 from eedle 132 and arrives clothes below by the position of its cut-out, and as shown in Fig. 5 F, and diagonal applies line tension.Then, eedle 132 advances to a new starting position 410 with respect to cloth 12, that is, bridge section or cloth can move, or the two all moves, and tape, to the cloth top, then is started to sewing, as shown in Fig. 5 G.
Then, no matter whether use before this moment curette 890, carry out pleating (tuck) cycle of top line, wherein operate sewing head through a stitching cycle, the top line tail is arrived below clothes 12 through cloth 12, caught by looper 216 herein, as shown in Fig. 5 H.Then, formerly front regulating wheel 402 starts under the top line 222 tension force effects that apply, and eedle 132 is done exercises by the kerf with respect to cloth 12, leaves and get back to the original position 410 of line through cloth 12, as shown in Fig. 5 I.For this motion, the pattern choice direction that controller 19 is sewed by translation.This motion is enough to move remaining top line tail to cloth 12 bottoms or looper side, and will not pull out cloth by the top line tail again.The length of this motion can be different for different application.
Moving line can be that for example, straight line, circular arc, triangle, straight line and circular arc and combination or some other motion or combination, can take eedle to 410 two inches of distance and positions or be less than two inches.According to length Machinery Design or line of cut tail program composition, can use different path lengths.Route preferably is orientated, and any top line produced at eedle 132 is loose, is arranged in pattern route one side of avoiding line to be absorbed in sewing pattern or being encountered by eedle 132.For quilting machines 10, preferably, the realization of this motion is by keeping cloth 12 static and along the route on the parallel cloth 12 planes bridge section 21,22 that moves.When pleating end cycle, machine is in position shown in Fig. 5 J.
The needs that start of pattern are sewed up element--eedle 132 and looper 216 co-operatings, thereby upper thread 222 and looper thread 224 are alternately picked up the wire loop that other line forms, and start to form chain-type stitch.When in the middle of the stitching sequence, carrying out the stitching cycle period,, once chain starts to form, eedle 132 descends and picks up through cloth 12 ring 412 formed between looper 216, top line 222 and looper thread 224, be sometimes referred to as triangle, the formation of ring is that the action by stop or distributor 234 realizes, as shown in Fig. 5 K (for Fig. 5 F more thoroughly explained referring to U.S. Patent No. 5154130.Fig. 5 A-5G of the present invention is the sequential illustrations that a common chain-type stitch forms the cycle).But line not yet is arranged in cloth 12, looper thread 224 stops below needle plate 38 and below stop 234.Particularly, looper thread 224 is clipped in (Fig. 5 J) between cutting knife 852 and elastic clip 856.Therefore, triangle 412 does not also exist by its normal form, and this ring is caught and needed not to be fully predictable by eedle 132.As a result, miss the possibility increase of the first stitching.The more important thing is and have a kind of unacceptable possibility, that is, will miss each stitching subsequently, until when the stitching of some uncertain quantity week, after date formed the first stitching.This will cause defective product and need repairing product or scrap products.
Have been found that by control wire, make looper pick up the top line ring before eedle is picked up the bottom line ring, greatly improve the reliability that while starting sewing pattern, stitching forms.This can realize by redirecting the looper thread tail.More reliably, this can also sew up element by change and constantly realize toward each other, that is, eedle is constantly with respect to the looper moment, thereby the first ring of picking up is the top line ring of being picked up by the looper that advances.This also can, by the moment of control wire like this or stitching element, make eedle miss the bottom line ring when eedle descends for the first time and complete.A kind of mode that said process is occurred is to guarantee that when eedle descends for the first time eedle reaches " mistake " side of bottom line.When the looper side when the looper thread tail from the looper point along eedle is returned, bottom line " mistake " side in eedle.
Before starting sewing, after eedle 132 moves to a reposition of cloth 12, eedle 132 is above cloth 12, and top line 222 passes 132 of eedles from bobbin to the line tail.At a normal stitching, in the cycle, eedle 132 is from the cloth top, and as shown in Fig. 5 L, looper 216 advances as shown in the figure.The tail of looper thread 224 is below needle plate 38 and below stop 234.When tradition starts, looper 216 descends and retracts with eedle 132, may be, but optional, between bottom line 224 and looper 216, pass, as shown in Fig. 5 M, form the bottom line ring, as shown in Fig. 5 N.This makes looper thread 224 be wrapped in the following upper thread 222 near looper 216 of stop 234, as shown in Fig. 5 O, forms the triangle of distortion, increases the possibility that eedle 132 misses its ring next time descended.
According to one embodiment of present invention, when in Fig. 5 P starting position, this is similar with figure L's, and eedle separates with the looper driver, and eedle remains on its dieback dot center position.The looper driver half period of then advancing, make looper 216 move to the position shown in Fig. 5 Q, thereby looper 216 retracted from the route of eedle 132.Then, the looper driver remains on its half period position, and the eedle driver starts simultaneously, makes eedle 132 drop to its half period position, eedle 132 and bottom line 224 is separated, as shown in Fig. 5 R.Then, eedle with the looper driver, again link together and together with advanced in unison, looper 216 starts to pick up the eedle ring near 3/4ths positions in stitching cycle thus, as shown in Fig. 5 S, and proceeds to from here the complete cycle position shown in Fig. 5 T.Then element continues motion through next cycle, now can form by the version stitching, as Fig. 5 U to as shown in 5X.Roughly, in the position of Fig. 5 X, the looper thread tail is pulled out from the holding action of thread cutter.
Eedle separates when starting with the looper driver, as mentioned above, misses stitching while avoiding starting.Eedle with there is other purposes separating of looper drive periodic, for example be convenient to the pruning of line.
As the another kind of mode of using above-mentioned beginning partition method, miss the possibility of stitching in the time of can reducing to start by the line tail that redirects or guide looper thread, thereby prevented that before the top line ring is picked up by looper the bottom line ring from being picked up by eedle.Realize that this redirecting can, by movement or other location (Fig. 5 J) of thread cutter and clip 850, make looper thread 224 tails leave the eedle side of looper.Can use line pusher mechanism or other looper thread to redirect technology, make looper pick up the top line ring before eedle is picked up the bottom line ring.
Increasing the another kind of phenomenon of missing the probability of stitching while starting is, distributor or stop 234 can not form triangle with looper thread 224, until towards needle plate 34 and cloth 12 stretch bending needlework 224.The looper thread 224 of being clamped by thread cutter 850 remains to and arrives stop 234.Before sewing starts, may be loose at the considerable looper thread of looper thread urogenesis between the clip position of looper 216 and thread cutter 850.Thisly loosely can form the large wire loop that swings to the opposition side of looper from eedle, reduce to pick up the possibility of stitching in any period demand, or even after eedle descends for the first time, thereby the beginning of stitching chain postponed unpredictablely.This delay can form unacceptable long gap in sewing pattern, needs repairing or abandons the material piece.Can reduce the loose possibility that causes these problems of this looper thread by the restriction looper thread.Realize that this restriction can be by dress looper thread deflector 430 below needle plate 38, as shown in Fig. 5 Y.Can leave the direction of looper thread 224 tails of looper 216 for being controlled at while starting such as the structure of line deflector 430, and affect the spacing of looper thread tail and looper, make eedle 132 can after looper is picked up the upper thread ring, not miss the looper wire loop.No matter whether this structure of picture looper thread deflector 430, use the beginning isolation technics, all improves the reliability that stitching forms.In some cases, the reliability of raising is enough to allow to omit the beginning separation characteristic.
Fig. 5 Y also means traditional eedle protection section 460, and it is contained on the pedestal 805 of looper 216, and this is illustrated in Fig. 4 D better.By it pivotally is contained on looper 216, and be locked in (Fig. 4 D) in hole 461 by bolt (not shown), can regulate eedle protection section.This eedle protection section 460 prevents from descending eedle 132 partially on the right side of advancing looper 216, makes it remain on the looper left side, and as shown in Fig. 5 R and 5S, thereby looper 216 is picked up ring and can not be jumped over stitching.
An improved embodiment that can select, as shown in Fig. 4 G, wherein has two-shipper pin protection assembly 470.Assembly 470 comprises the first eedle protection section 471 and the second eedle protection section 472.The function class that the first eedle protection section 471 carries out is similar to eedle protection section 460, and also hingedly adjustable ground be contained on the pedestal 805 of looper 216.The second eedle protection section 472 is rods of a kind of circular cross-section, and adjustable ground is contained in the hole of mounting blocks 473 and can rotates, and mounting blocks 473 is rigidly fixed to the looper side of needle plate 38.Eedle protection section 472 eedle 132 that prevents from descending further is biased to the left side of the looper 216 that advances, thereby looper 216 can not arrive the right side of upper thread 222, misses the top line ring and skips stitching, but being through (Fig. 5 S) between upper thread 222 and eedle 132.The second axis 474 of eedle protection Bu472 center in parallel looper plane of movement and needle plate plane of circular cross-section, be the horizontal of level in described machine.Eedle protection section 472 has eccentric pedestal 475, and its axis 476 separates with axis 474 but be parallel, and eccentric pedestal 475 is contained in piece 473 holes.Like this; eedle protection section 472 adjustable grounds are contained in the installing hole of piece 473 and can rotate; thereby make itself or its axis 474 towards eedle 132 motions or leave eedle 132, being fixed on its position by the Allen bolt 477 of tightening piece 473 herein.
Technology for the noose stitching sequence of sewing also is improved, and reduces to miss the possibility of stitching, particularly in starting noose stitching sequence process.Preferably, start noose stitching sequence and be to want the sew short distance of about an inch of the direction of pattern to start by edge, before then continuing forward on the line of identical stitching, on initial stitching, sew and get back to starting position.When starting, several long stitchings of sewing, be then the stitching of normal length.Typical normal stitching rate can be the several stitchings of per inch.In order to start the noose sequence, at first line is arranged on to the initial point of pattern curve, this can use above-mentioned striking off and the pleating cycle.Then the stitching in two triple-lengths of direction sewing of leaving initial point along the pattern curve, be then the stitching of a normal length.The stitching of 7 normal lengths of then sewing is got back to initial point.And then put upside down sewing direction, surpass initial stitching along the sewing of pattern curve.
When normal sewing pattern, the conveying of bridge section or cloth or simultaneously carry the two, preferably form and sew up elements relative in the continuous conveying action of cloth.But, in the noose sequence, particularly, in those parts of using the noose sequence longer than normal stitching, the conveying obtained is intermittent.But intermittent delivery is preferably not unexpected, but in not slower this motion in inserting cloth of quick relative movement and eedle or there is no mild transition between this motion between the stitching element in cloth and cloth of eedle.When sewing normal length stitching, or the long stitching of sewing before or afterwards, carry preferably continuous in stably.
Usually, the high speed sewing when quilting pattern is undertaken by continuous stitching sewing, and the motion of eedle is the time or is at least the SIN function of needle gage.In above-mentioned so-called intermittent delivery process, eedle motion can be thought the non-sine function of distance, when eedle puncture cloth eedle move back and forth faster than sine, slower when eedle is extracted out from cloth.The transition of eedle speed can be mild.Such eedle velocity variations is applied in any sewing pattern use reverse situation.Sewing originates in eedle by the motion of the halted state with respect to cloth, is the useful another kind of situation of this eedle actuation movement.The noose sewing is the common example of these situations and this eedle velocity variations of needs.
For example, eedle speed can be from stopping beginning and moving under consecutive periods speed, making its action is the SIN function of time, but the conveying respect to one another of cloth and eedle is very fast when eedle is extracted out from cloth, slower when eedle puncture cloth, making the eedle motion is the non-sine function motion with respect to the distance of cloth.Under this motion, can sew and slightly be greater than average stitching, the cloth conveying of then puncturing between cloth at eedle can be reduced to gradually continuous sewing and continue the normal needle gage carried out.Then, when carrying out noose, eedle is put upside down with respect to the direction of cloth, and slightly is longer than the similar sequence of normal stitching by the motion of non-sine eedle, then is transitioned into the normal size stitching.No matter whether travel direction is put upside down, and can carry out similar system.This has reduced wrong formation stitching, has missed stitching and thread breakage.Realize that eedle can make bridge section move with respect to machine rack by (1) with respect to the motion of cloth, keeps cloth static simultaneously; (2) keep bridge section static with respect to machine, make cloth motion simulation simultaneously; Perhaps (3) bridge section and cloth while are with respect to the combination relative motion of machine rack.
The mode of carrying out above-mentioned motion can be, considers machine part and the inertia of cloth and other impact of cloth distortion and acceleration, deceleration, eedle deflection and other factors, optimizes or minimizes these impacts.For example, while normally sewing in the figure main case body, eedle can move back and forth by a series of stitching cycle sine of relative motion between cloth and eedle, is parallel to the motion on cloth plane, and motion is continuous, under constant speed.In this example, eedle can per minutely move back and forth 1400 circulations, and eedle is 200 inches per minute with respect to the motion of cloth.Then, when sewing noose sequence, the speed of this parallel motion and reciprocating engine needle movement can slow down by direct ratio, that is, be respectively 100 inches and 700 circulations per minute per minute.Then; for the noose stitching; eedle moves back and forth that speed can change and the non-sine motion; for example; can puncture the partial periodicity of cloth with the motion of the speed of 2100 circulations of per second at eedle, then between the puncture cloth, slow to per second hundreds of or still less, the stitching of sewing normal length or the long stitching than normal length; can order as controller, make eedle deflection minimum and cloth distortion minimum.Like this, eedle moves back and forth when the puncture cloth and accelerates to larger circulation rate, between the stitching puncture, decelerates to slower circulation rate.Be transitioned into normal stitching or from before or after normal stitching transition at the noose stitching, the transition stitching of can sewing.This sequence can be for noose stitching sewing, or when in any pattern, sewing direction is put upside down.
A linear servo motor stator 39 is contained in frame 11 each side and vertically extends, and is parallel to vertical rail 40.The armature of linear servo motor 35,36 is separately fixed on each platform 41 of lower and upper lifter 33,34.Controller 19 is controlled lower servomotor 35, make the upper and lower motion on stator 39 of lower bridge section 21, keep bridge section 21 opposite ends levels, and on controlling, servomotor 36 makes bridge section 22 upper and lower motion on identical stator 39, keeps the opposite ends level of bridge section 22 simultaneously simultaneously.Vertically travel mechanism 30 comprises digital encoder or decomposer 50, and each lifter carries one, and accurately the position of measuring table 41 on track 40, feed back to controller 19 by information, contributes to accurate location and the level of bridge section 21,22.Although be preferred such as the linear electric machine of linear servo motor, also can use other driver, for example ball bolt and rotating servo motor, or other drive unit.Encoder 50 is preferably exported the absolute encoder of actual position signal.
Kinematic system 20 comprises transverse horizontal motion 85, for each bridge section 21,22.Each bridge section 21,22 has a pair of tongue 49, and opposite ends left side right from it stretched out rigidly, bridge section 21,22 is supported on the platform 41 of lifter 33,34.Tongue 49 laterally moves under the operation of transverse horizontal bridge section motion 85 on lifter platform 41.The laterally extending guide structure 44 of tongue 49 carrying of each bridge section 21,22, guide structure 44 is with the track form in the bearing 43 of the platform 41 across corresponding lifter 33,34 (Fig. 6 A and 6G).Linear servo motor stator bar 60 is fixed on the tongue 49 of each bridge section 21,22 1 side, and parallel orbit or guide structure 44 extend.The armature of linear servo motor 45,46 is fixed on a platform 41 of each corresponding bridge section 21,22, and its installation is in response to signal and stator pole 60 co-operatings the transverse shifting stator pole 60 of controller 19.The transverse horizontal motion comprises the decoder 63 of each bridge section 21,22, is positioned near the armature of servomotor 45,45 of corresponding lifter platform 41, and horizontal bridge section position information is fed back to controller 19, contributes to the accurate control of horizontal bridge section position.Bridge section the 21, the 22nd, independent controlled, thus vertical upper and lower motion and horizontal left and right motion, and with coordination mode operation, the quilting pattern of sewing on cloth 12.In illustrated embodiment, but 18 inches of each bridge section transverse shiftings (9 inches of decentre position +/-), and each bridge section can move up and down 36 inches (18 inches of decentre position +/-).The vertical moving range of lower and upper bridge section 21,22 can be overlapping.
The driven roller 18 at frame 11 tops is also the part of whole kinematic system 20, is that the conveying servomotor 64 by frame 11 tops drives, and as shown in Figure 6, this carries servomotor 64 on the right side of frame 11 (for the downstream).When starting, servomotor 64 driven roller 18 downstream transport cloth material strip material 12, and it is upwards drawn between the part 23 and 24 through quilting stations and two bridge sections 21 and 22 along plane 16.Roller 18 also drives the Timing Belt 65 on the frame 11 in quilting machines 10 left sides, as shown in Figure 6A.Each bridge section 21,22 also can have a pair of pinch roll 66, replaces dummy roll 15, and its axle journal is contained on the corresponding lifter platform 41 of the corresponding bridge of support section 21,22.These rollers 66 are clamped cloth 12 at the height of bridge section 21,22, make the height minimum of the transverse shifting of cloth at sewing head 25,26.Pinch roll 66 is by being with 64 synchronously to drive, thereby, in the district of nipping that becomes pair roller 66, its surperficial tangential motion drives cloth 12.
As shown in Figure 6A, utilize the static lifter platform 41 of supporting bridge section 21,22, starter motor 64, by driven roller 18, advances downstream and upwards band material 12 between the pinch roll 66 of bridge section 21,22.Then, roller 18 rotates the band driving cogwheel 600 in frame 11 left sides, rotating band 65.The roller 66 of two bridge sections 21,22 is driven by the motion with 65, thereby when bridge section 21,22 vertically fixedly the time, they have identical tangential velocity, when cloth 12 is driven while making progress with cloth 12 rollings by the motion of roller 18.On the other hand, when conveying roller 18 and cloth 12, when static, be with 65 maintenances static, as shown in Figure 6B.When being with 65 when static, any bridge section 21,22 moves up or down, will force roller 66 with respect to 12 motions of band material, also with respect to being with 65 motions.Roller 66 is with respect to being with 65 motions to make roller 66 rotation, and rotary speed make between them the to nip roller surface in district keeps static on band material 12, thereby roller 66 rolls along static cloth material strip material 12 surfaces.In addition, the aggregate motion of band material 12 and bridge section 21,22 is with the aggregate motion that is delivered to roller 66, effectively deduct moving upward of bridge section 21,22 from the moving upward of band material 12, thereby be with cloth 12 motions at the total surface of the roller 66 in the district of nipping of the roller 66 complete.Being synchronized with the movement between the pinch roll 66 of band material 12 and each bridge section 21,22 keeps longitudinal tension force on cloth 12, and clamps cloth 12 in each bridge section 21,22, the horizontal cloth distortion of opposing band material 12.
Make, with the 65 synchronous structures that drive the motion of pinch roll 66 and bridge section 21,22 and band material 12, also to be illustrated in Fig. 6 C and 6D, and Fig. 6 A as above and 6B.Be with 65 to walk around inserted tooth driven roller 600, the latter drives (Fig. 6 D) by conveying roller 18 by gear assembly 601.Be with 65 also to walk around drive pulley 606 and loose pulley 607, the two is contained on the lifter platform 41 of lower bridge section 21 and can rotates; And walk around loose pulley 608 and drive pulley 609, the two is contained on the lifter platform 41 of bridge section 22 and can rotates, and all these are in frame 11 left sides.Drive pulley 606 is to be driven by the motion with 65, and by gear mechanism 610(Fig. 6 D) drive the pinch roll 66 of lower bridge section 21; And drive pulley 609 is also driven by the motion with 65, and drive the above pinch roll 66 of bridge section 22 by gear mechanism 611.Gear mechanism 610 and 611 drive ratios with respect to driven wheel mechanism 601, making the tangential velocity of roller 66 and roller 18 is zero with respect to band material 12.It should be noted that the position regardless of bridge section 21 and 22, it is identical that the route with 65 keeps.
In addition, to be illustrated in the bottom of Fig. 6 D and Fig. 6 E, 6F be a pair of roller that is similar to roller 18 to entrance roller 15.If so provide and drive these rollers 15, and, according to the induction system of the band material 12 of quilting machines 10 upstreams, these rollers can be that need or unwanted, thus roller 15 also by being with 65 drivings, the gear mechanism 612 driven as the roller 605 with 65 drives.In this case, by the gear ratio of coupling rightly between mechanism 601 and 612, roller 15 should keep the tangential velocity identical with conveying roller 18.But, preferably making roller 15 rotate freely as dummy roll, and only provide single roller 15 with upstream side above cloth 12, cloth 12 is wrapped in around it.The diagram as gear mechanism 612 is the same with explanation substantially with 611 for each gear mechanism 601,610.
The downstream motor coordination that vertically moves through controller 19 and cloth material strip material 12 of bridge section 21,22.The coordination mode of motion, remain in its 36 inches vertical stroke range bridge section 21,22 effectively.In addition, the motion of two bridge sections 21,22 makes the different piece of sewing different pattern or pattern.Like this, its independent motion is also coordinated, thereby two bridge sections 21,22 remain on it separately in stroke range, and this may need them to operate under different sewing velocities.Its realization can be controlled a bridge section by controller 19 is independent, and the motion of another bridge section depends on or be subordinated to another bridge section, but other movement combination may adapt to different pattern and situation better.
Control the operation of two eedles driving servo-drive systems 67 of the common eedle driving shaft 32 that drives respectively each bridge section 21,22 by controller 19, the speed of controller syringe needle 25.Similarly, two loopers controlling the common looper band drive system 37 that drives each bridge section 21,22 by controller 19 drive in each bridge section 21,22 of servo-drive system 69(one) operation, control the speed of curved needle head 26.By the different operating of two servo-drive systems 67 and two servo-drive systems 69, the sewing head 25,26 in different bridge section 21,22 can be driven under different rates.But needle head 25 and the curved needle head 26 of identical bridge section 21,22 move under identical speed, and synchronously coordinate to form stitching, but these can be relative to each other phasing slightly, for suitable ring pick up, eedle deflection or other purpose.
In addition, the horizontal movement of bridge section is controlled in some cases, and they are moved in opposite directions, thereby the sewing operation of carrying out by any bridge section 21,22 is tending towards eliminating cloth 12 transversely deformings.For example, when two bridge sections 21,22 are sewing identical patterns, can control them and in the opposite direction form circle.Different pattern also can be controlled, thereby actual capabilities are eliminated the cross force that acts on band material 12 to the greatest extent.
Above-described embodiment has independent driving servo-drive system, for needle head assembly 25 and the curved needle head assembly 26 of each bridge section 21,22.Particularly, each bridge section 21,22 comprises that eedle drives servo-drive system 67, and the signal of controlled device 19 is controlled respectively, driving shaft 32; Then drive all needle head assemblies 25 of each bridge section, each needle head assembly 25 is optionally meshed by clutch 100, this is also by the signal manipulation of controller 19.And, each bridge section 21,22 also comprises that looper drives servo-drive system 69, also separately by the signal controlling of controller 19, rotating band 37, drive thus all curved needle head assemblies 26 of corresponding bridge section, each curved needle head assembly 26 is selectively meshed by similar clutch 210, and this is also by the signal manipulation of controller 19.Independent driver 67 and 69 is convenient to start separation characteristic, as mentioned above, and the eedle deflection compensation, can also be applied to other controlled working.
Here also illustrate and described a lot of other feasible bridge section designs, needle head assembly and eedle and looper and control thereof.Express end portion or the tongue 49 of bridge section 21 or 22 in Fig. 6 H, wherein eedle drive motors 67 drives needle head assembly 25 and the curved needle head assembly 26 of same bridge section simultaneously after connecting.The direct driver output axle 32 of servomotor 67, this is the eedle driving power shaft of this bridge section.Axle 32 drives inserted tooth band 32a thus, and inserted tooth band 32a drives looper to drive power shaft 37a, and looper drives power shaft 37a to replace the looper rotating band 37 of previous embodiment.For this embodiment, eedle 132 drives together with looper 216, is not separately to control or phasing.Owing to sewing up element, be mechanical connection, dynamic failure and other fault seldom cause the mechanical failure of machine.Yet recovering the independent ability of controlling eedle and curved needle head can drive servo-drive system 69 by retaining looper, and by differential driving 69a, its output is connected to axle 37a, differential driving 69a is increased between tape drive 32a and looper driving shaft 37a.
Looper driving shaft 37a is connected to segmentation axle 37c by band 37b, and the latter forms by the torque tube 37d of alternate series and gear-box 210a.Gear-box 210a replaces looper driving clutch 210, but drives continuously looper and the stop driver 212 of curved needle head assembly 26, rather than optionally drives each as front embodiment is described.Eedle is enabled separately or is stopped using and determines whether this cover stitching element participates in the pattern sewing.Although clutch 210 can replace gear-box 210a, due to looper 216, not through the cloth be sewed, no matter whether driven corresponding eedle driven unit 25 is, and looper 216 can continuous service.
The curved needle head assembly 26 of this embodiment, assembly 26a as shown in Figure 2 C, comprise looper substantially as above and stop driver 212.They each also comprise needle plate 38, be illustrated as rectangular slab 38a, with respect to the looper drive enclosure 238 with pin hole 81, fix.Each gear-box 210a has output shaft, by the axle collar 440, be locked on the power shaft of looper and stop driver 212, thereby these axles relative to each other only axially can be regulated.Each gear-box 210a is supported by two bearings 441, and each side of gear-box 210a has one, around the axle 37c as gear-box 210a input drive shaft.Each bearing 441 is fixed in holder 442, and latter's bolted is in bridge section.Like this, gear-box 210a is only axially adjustable with respect to axle 37c.
When curved needle head assembly 26a is contained in the rear portion 24 of bridge section 21,22, can carry out 4 adjustings.Two Level tunes can be for regulating the assembly 26a in bridge section.Before screw down clips gripping member 442, gear-box 210a can located lateral on axle 37c, make eedle hole 81 lateral alignment eedles 132.Then can unclamp the axle collar 440, assembly 26a is moved or leaves it towards eedle driven unit 25, thereby regulate needle plate 38a with respect to fabric plane 16.The angular adjustment of looper and stop driver 212 can be by the driver 212 by shell 238 the disk (not shown) of power shaft with the aligned hole 444 of shell 238, align.This is by the axle through hole 444 rotary driver 212 by straight pin (not shown), until pin inserts the hole of alignment disk.When completing adjusting, tighten the axle collar 440.The vertical adjusting of looper 216 is to have regulated by reference to the above-mentioned looper of Fig. 4 E.
Fig. 2 C also expresses the needle head assembly 25 that produces the motion of simple sinusoidal eedle, and camera needle assembly embodiment 25a is the same.Each needle head assembly 25a comprises clutch 100, for optionally power being delivered to eedle driver 102a and presser foot driver 104a from eedle driving shaft 32.Eedle driver 102a, presser foot driver 104a and clutch 100 and axle 32 are supported on eedle drive enclosure 418.Eedle driver 102a comprises crank 106, by output belt pulley 166 process rotating bands 164 drivings of clutch 100.Crank 106 is mechanically connected to eedle retainer 108 by direct eedle drive link 110a.The arm of crank 106 or eccentric 112 is connected to connecting rod 110a mono-end and can rotates.The other end of connecting rod 110a is connected to the pin 123 that the piece 122 from moving back and forth axle 124 stretches out and can rotates, and axle 124 is extensions of eedle retainer 108.Axle 124 is installed rear reciprocating linear motion, as above with reference to the described assembly 25 of Fig. 2.Presser foot driver 104a is similar to the described presser foot driver 104 above with reference to Fig. 2 A substantially.The element of needle head assembly 25a is by allowing head not needing the material operated under lubricating condition to make.
In typical structure, quilting machines 10 quiltings can be transported downstream to the band material 12 of material piece cutting machine and trimmer, or quilting can roll and be sent to the band material 12 of off-line cutting and clipping device.The motion of band material 12 and bridge section 21,22 also can be harmonious with the material piece cutting operation that the material piece cutting assembly 41 at frame 11 tops is carried out.Material piece cutting machine 71 just has in the cut-out of the driven roller 18 cross-section band material 12 in downstream 72, and in a pair of pruning of frame 11 two opposite sides or rip cutting 73, and rip cutting 73 is near cutting off 72 downstream, for pruning the selvedge of band material 12 both sides.
Cut off 72 and be contained on track 74, from the position of rest in frame 11 left sides, traverse across frame 11.Connect to the end 72 by exporting with inserted tooth band 76, the AC motor 75 be fixed on frame 11 drives these heads to move on track 74.Cut off 72 and comprise a pair of cutting wheel 77 rolled along the contrary side of cloth 12, make cloth 12 between the two, thereby expect 12 preceding limb transverse cuts quilting material piece from band.Take turns 77 gears and connect to the end 72, the speed of taking turns 77 cutting edges is directly proportional to a speed of 72 traverse tracks 74.
When the material block edge correctly is positioned at the cutting position that cutting wheel 77 courses form, controller 19 makes to cut off an operation of 72 and synchronizes with motor 75 startups.When cutting off action, controller 19 makes cloth 12 motions stop at this position.In cutting operation process, controller 19 can stop the sewing that sewing head 25,26 is carried out; Perhaps, when material 12 stops being cut, can continue sewing by motion bridge section 21,22, make sewing head 25,26 carry out any vertically moving with respect to cloth 12.
Rip cutting 73 is pruned or rip cutting when cutting head 72 moves downstream at the band material of cut cloth 12 or material piece.Each rip cutting 73 has a set of relative conveyer belt 78, with a pair of rip cutting wheel 79, coordinates to drive.The U.S. Patent No. 6736078 that the structure of these rip cuttings 73 and the detailed explanation of operation are submitted on March 1st, 2002 referring to people such as Kaetterhenry, title is " Soft Goods Slitter and Feed System for Quilting ", and this patent is incorporated herein by reference document.
Conveyer belt 78 79 moves with wheel together with tooth, and when band expect 12 while advancing through rip cutting 73 by the drive systems of conveying roller 18.At cutting head 72 after band material is cut material cutting block, be with 78 with conveying roller open shop in 18 minutes, will expect that piece is from being with 78 supernatants to fall.Rip cutting 73 laterally can be regulated on the laterally extending track 80 that strides across frame 11 width, thereby adapts to the band material 12 of different in width, as U.S. Patent No. 6736078, discloses.This adjusting is under the control of controller 19, to carry out after the material piece is cut off and removes with 78 from pruning.Rip cutting 73 and the lateral attitude on frame 11 thereof are adjusted to consistent with the edge of cloth 12, are to carry out under the control of controller 19, and its mode is according to U.S. Patent No. 6736078 and with reference to the explanation here.
Use said structure, controller 19 is along forward direction moving belt material, make bridge section up and down, the right side and left movement, make lower bridge section up and down, the right side and left movement, the Kai Heguan of selective each eedle of conversion and looper driver, and control eedle and the right speed of looper driver, and all with various combination and composite sequence, very pattern and the operation efficiently of wide region are provided.For example, the sewing of simple line is very fast and multiple combination arranged.With previous quilting machines, compare, the sewing pattern of continuous 180 degree patterns (Yi Bian those are from being sewn into opposite side only proal) and 360 degree patterns (those need oppositely sewing) is many, and speed is fast.Discrete pattern, needed a pattern part, sewing noose stitching, cut off line and jumped to the beginning of a new pattern part, can be sewed with more pattern and higher efficiency.Different pattern can connect.Different pattern can be sewed simultaneously.Cloth can move or be static when sewing pattern.Sewing can be synchronizeed and carry out with the cutting of material piece.The material piece can be sewed under different eedle speed, and the pattern different piece can sewing simultaneously under friction speed.Eedle arrangement, spacing and position can change automatically.
For example, the simple straight line of sewing parallel band material 12 length can be by being fixed on select location by bridge section, and then only the operation by driven roller 18 is advanced through machine band material 12.Drive sewing head 25,26 o'clock, form under the speed that stitching is synchronizeed in the speed with the band material, thereby keep required stitching density.
The continuous linear that band material 12 is crossed in sewing can and move horizontally bridge section by fixed band material 12, operates similarly sewing head simultaneously.A plurality of sewing heads can operate in the bridge section of motion simultaneously, the fragment of sewing same lateral line, thus the motion of bridge section only needs to equal the level interval between eedle.As a result, the x wire sewing is very fast.
When being machine stitching, continuous pattern repeatedly repeats those patterns that the identical patterns shape forms.Only by band, expect can be called the standard continuous pattern with respect to the available continuous pattern of sewing head one-way movement, wherein sewing head connects into transverse shifting.This is sometimes referred to as 180 degree patterns.Their sewing on quilting machines 10 are by the vertical position of fixed bridge section and move conveying roller 18 and make 12 motions of band material, and only make 21,22 horizontal movements of bridge section.On quilting machines 10, band material 12 is not with respect to frame 11 transverse shiftings.
Fig. 7 A is an example of standard continuous pattern.For all eedles traditional multineedle sewing machine of identical patterns of sewing simultaneously, as long as there is the eedle of the two between-line spacing distance B illustrated pattern 900 of can sewing.Distance B is the preset parameter of machine, can not change with pattern is different.This is to fix because of the eedle line-spacing, and all eedles must move together.For quilting machines 10, as mentioned above, distance B can be arbitrary value because alternately stitching can one eedle sewing in bridge section, other stitching can be sewed with the eedle in another bridge section simultaneously.These two bridge sections can be by any motion of relation toward each other.In addition, if two bridge section intervals vertically apart from 2D, the eedle of each bridge section starts at point 901 and 902, for example, when they can material going along be upwards carried, along opposite lateral, move, thereby the alternate row 903 of sewing out with 904 as identical mirror image.By this way, can eliminate the motion of bridge section and act on the cross force on cloth, thereby make the cloth distortion minimum.
The continuous pattern that need to move with respect to sewing head two-way tape material is referred to herein as 360 degree patterns.These 360 degree patterns can be sewed by various ways.Band material 12 can keep static in a pattern repeat length, with the motion of bridge section, completes whole sewing, then band material 12 advance a repeat length, stop, and next repeat length also can only be sewed by the motion of bridge section.More effective and method high yield of this 360 degree continuous pattern of sewing comprises advances band material 12, forms the required vertical band material part of pattern and moves with respect to head, and the sewing of bridge section is only by the horizontal movement with respect to band material 12 and frame 11.When a point of pattern reaches while needing oppositely vertically sewing direction, stop band material 12 by stopping conveying roller 18, and the one or more bridge section that carries out sewing moves upward.Must be again oppositely the time when vertical direction, bridge section moves downward, and the band material is still static, until bridge section reaches initial position, from then on position start its vertically mobile and band material motion stop.Then recover the motion of band material, carry the pattern vertical portion until pattern needs again reverse.The combination that bridge section and band material vertically move prevents that bridge section from walking out scope.
An example of 360 degree continuous pattern 910 is illustrated in Fig. 7 B.This pattern sewing starts, and for example, at point 911, and vertical curve 912 is only by upwards vertically band material motion sewing.Then, at point 913, band material stops and only with the motion of horizontal bridge section, horizontal line 914 is sewn into a little to 915, then only by the bridge section motion that makes progress, be sewn into suture 916, then only laterally bridge section move to sewing thread 917, then only downward vertically bridge section moves to sewing thread 918, and the laterally bridge section of only following moves to sewing thread 919, and then only downward vertically bridge section moves to sewing thread 920.Then, only with horizontal bridge section motion sewing thread 921, then only with bridge section motion sewing thread 922 upwards, then only with horizontal bridge section motion sewing thread 923 to point 924.At this point along the line 923, it is following than any point of pattern maximum distance far away all that bridge section arrives its initial position.Then, bridge section moves downward sewing thread 925 as far as point 926, the close point 915 that vertically bridge section moves and starts of this point, and at point, its initial vertical position is got back to by 926 bridge sections, and its vertical mobile stopping, being with material to move upward sewing thread until put 927 thus.Then, only laterally bridge section motion sewing thread 928 to point 929, the starting point of getting back to pattern.
The discontinuous pattern partly formed by discrete pattern, assignee by the applicant is called the TACK&JUMP pattern by trade mark, according to the mode identical with continuous pattern, sew, the noose stitching is carried out in beginning and end at each pattern part, trim lines after each pattern part completes, and make cloth with respect to eedle advance to next pattern start the place.180 degree and 360 degree patterns are processed into continuous pattern.An example of this 360 degree patterns 930 is illustrated in Fig. 7 C.A kind of plain mode of this pattern of sewing is the motion sewing pattern with bridge section, and noose pattern line of cut then only jump to next the repetition with the motion of band material.But the motion of the band material shown in Fig. 7 B is increased to pattern sewing part can productivity gain.
According to the described concept of U.S. Patent No. 6026756, different pattern can link together.Fig. 7 D is an example of the connection pattern that can sew on quilting machines 10, wherein there is no the vertical movement of bridge section, the opposition side that two bridge sections become mirror image by the sewing four-leaf clover shape pattern 941 of jointly sewing.In addition, a bridge section can sew as the pattern 941 of 360 degree discontinuous pattern, simultaneously another bridge section sewing straight-line pattern.
Fig. 7 E means continuous 360 degree patterns 950, and its sewing is with a bridge section one of them pattern 951 of sewing, the sew mirror image 952 of identical patterns of another bridge section.This pattern 950 is to use with the pattern 910 of Fig. 7 B similarly to be with the vertical mobile logic sewing of material and bridge section.In minute timing of determining the vertical movement between bridge section and band material, controller 19 was analyzed pattern before sewing starts.In such decision, the beginning repeated at each pattern, the identical when lateral attitude while repeating to finish must start with pattern, and vertically be with material level to put must identical or trip (upstream) more on the lower.The sewing of pattern 950 can be with lower bridge radicals by which characters are arranged in traditional Chinese dictionaries first sew a little 953 noose stitching sewing pattern 951.This sewing will use the horizontal movement of bridge section and only the band material is vertically mobile, until the point of arrival 954.Then, the band material stops, and bridge section vertically sews, make progress again downwards, and the point of arrival 955, at this point, watchman's wooden clapper is in the lengthwise position with its identical band material at point 954 and identical vertical position.Then, recover the band material and carry and once vertically move, and for this sequence that repeats of the second half patterns 956.
When the point of arrival 957, the second bridge section starts pattern 952, and the noose stitching, at point 953, by the mode identical with the first bridge section sewing pattern 951, sew, but level or horizontal direction is reverse.Sewing is proceeded, and for two patterns 951 and 952, bridge section is identical with the band material and simultaneously vertically mobile.Sewing is proceeded, until the lower bridge section point of arrival 958, and the noose stitching cut off line of sewing herein.After repeating an above pattern, the second bridge section arrives identical point, and sewing noose stitching cut off line.
Form another pattern by move a bridge section pattern of formation another bridge section that moves, two different patterns can be sewed simultaneously.The operation of two bridge sections and the sewing head above it is controlled with respect to public imaginary axis, the speed of this imaginary axis can increase, until a bridge section arrives its maximal rate, and another bridge section is moving than under low velocity, and velocity ratio is determined by the pattern demand.The pattern 960 of Fig. 7 F means that this on the one hand.With the vertical curve of a bridge section sewing pattern 961, another bridge section is the Z-shaped line of sewing pattern 962 simultaneously, and the sewing speed of two bridge sections must be different.Because the sewing series of pattern 962 is longer than pattern 961, therefore with imaginary axis or maximum sewing velocity under drive pattern 962 under the reference value 1:1 ratio that arranges.If the line of pattern 962 is miter angles, for example, the sewing speed of pattern 961 will be set as 0.707 times of speed of pattern 962.
Sewing pattern can by composite bridge section when cloth advances vertically and horizontal movement, thereby make process optimization become possibility.Fig. 7 G, for example, mean pattern 970, and it is formed by straight border pattern 971 combined diamond shape patterns 972 and circular pattern 973.If whole material piece is greater than 36 inches vertical bridge section strokes, for example, if size L is 70 inches, sewing is carried out as follows: use 360 degree logics, when band material is static, the at first diamond of the material to be sewn piece first half 974 and circle, one of them bridge section sewing diamond, another bridge section sewing circle, or some other combinations.Then, sewing border pattern 971, in this process, the band material moves upward 35 inches, sews as mentioned above vertically and horizontal line.Then, the diamond of material to be sewn piece Lower Half 975 and circle.In addition, during the material to be sewn piece first half, the upper bridge upper circle of section's sewing and diamond shape pattern, the lower bridge lower circle of section's sewing and diamond (two row).Then, after the sewing boundary line, circle and the diamond shape pattern of material piece Lower Half can be distributed similarly between bridge section.
Use above-mentioned quilting machines 10, can sew or unpractical other pattern impossible for the prior art machine.For example, Fig. 9 means the part 500 of quilting band material 12, the above quilting two pattern parts 501 and 502.In order to simplify, select these two patterns as continuous unidirectional pattern, but the principle that these patterns of contact sewing are discussed, with the principle that a lot of patterns of the above-mentioned Fig. 7 of contact A-7G are discussed, be combined, produce other more complicated pattern and combinations of patterns, thereby the advantage of additional features and stitching process is provided.The pattern 501 and 502 of band material part 500 has some denominators and some special natures.These two is continuous unidirectional types of patterns, and each fixedly completes respectively on the eedle multi-needle quilter separately, and wherein identical patterns extends to another from a material piece.Pattern 501, for example, be called " cepaeform " pattern, by replacing, basic sine curve 503 and 504 forms.These curves 503,504 can be thought identical, but differ from 180 degree phase places, thereby their polymerizations separation form illustrated cepaeform pattern 501.Pattern 502 is called " diamond " pattern, is to be formed by the Z-shaped line 505 and 506 replaced.These lines or curve 505 and 506 also can be thought identical, but differ from 180 degree phase places, thus their also polymerizations separate to form illustrated diamond shape pattern 502.Two curves the 503, the 504th of pattern 501, formed by the pattern repetition period 507, and two curves the 505, the 506th of pattern 502 were simultaneously formed by the repetition period 508.These two patterns 501 and the 502 little length 510 by band material 12 are separately.
Each pattern 501 and 502 can be thought and is comprised of following part respectively: (1) initial length 511 and 512 strides across 180 degree of pattern repetition period or half; (2) intermediate length 513 and 514, stride across one or more 360 degree of pattern repetition period, or complete cycle; And (3) finish length 515 and 516, also stride across 180 degree of pattern repetition period.These length 511-516 is for moving upward in Fig. 9 through quilting machines 10 and from the top of figure to the band material 12 of bottom quilting.Pattern 501 and every curve of 502 start with noose stitching sequence 517, and finish with noose stitching sequence 518.The noose of these curves starts and finishes and vertically the approaching of the beginning noose stitching sequence 517 of the end noose stitching sequence 518 of a pattern and next pattern, and is the special advantageous characteristic of this aspect of the present invention.The length 210 of the band material 12 between pattern 501 and 502 can be less than pattern 180 the degree length, even be significantly less than, be for example 90 degree, 15 the degree or be 0 degree.Between pattern, length 210 may reside on the material piece that is comprised of two identical or different patterns of material piece, illustrated two patterns 501 and 502 for example, or may reside in two borders of expecting between piece.During border when interior pattern length 210 between two patterns, can be at this zone cutting material piece, thus make to expect cloth waste minimum or the Waste reduction of the band material 12 between piece.In Fig. 9, it is long that each pattern 501 and 502 is expressed as two pattern period, each respectively by the long initial length 511 or 512 of half period, complete cycle long intermediate length 513 or 514 and the long end length 515 or 516 of half period form.
Although each pattern 501 and 502 can be sewed on the prior art multi-needle quilter, for example U.S. Patent No. 5154130 is disclosed, and some restrictions are wherein arranged, as understandable with reference to figure 9A.This in part because, use traditional multi-needle quilter, the multirow eedle is contained on a public rigidity sewing header structure, eedle is fixed on this sewing head, and the capable constant spacing that is limited to of eedle, all eedles of all row are sewed simultaneously, and keep the fixed relationship definite in the layout of sewing head structure by it.These stitchings that simultaneously form are to utilize in position 521 and the first row eedle of each interval lateral separation 522, and in position 523 and the second row eedle of each interval lateral separation 524, two row eedles separate fore-and-aft distance 525.This eedle is arranged the relative dimensions part of the cepaeform design that forms pattern 501 in Fig. 9 A, particularly vertically.Similarly size restrictions comes from the eedle position 526 of article one lateral separation distance 527 and the eedle position 528 of second spacing distance 529.In Fig. 9 A, the lateral separation 527 and 529 of pattern 502 does not need (in Fig. 9 A not being) identical with the distance 522 and 524 of pattern 501.Due to the structural limitations of equipment, the fore-and-aft distance 525 of row is identical for pattern 501 and 502.These distances 525,527 and 529 form the size of the diamond design part of pattern 502 in Fig. 9 A.
Use every 4 eedles from every two eedles of sewing pattern 501() be transitioned in every two eedles of sewing pattern 502(and use every 7 eedles), as shown in Figure 9 A, need to change the eedle setting.For most prior art machine at least, eedle arranges normally manual operations of replacing.In addition, pattern 502 can replace with those patterns that 4 eedles identical with pattern 501 are used in restriction, for example has 4 row rather than the diamondoid pattern of 7 row, thereby change to pattern 502 from pattern 501, does not need to change eedle.And, because all eedles of the fixing machine of eedle are starting in the same time and stopping mutually, occupy any row with them irrelevant on sewing head; And put necessary longitudinal separation distance 525 by the start and stop bits sewing of different rows eedle and pattern curve 503 that be positioned at position 521 and 523 and 504 respectively, make to occupy only curve 503 of certain-length band material or 504 half length part, beginning and end in each pattern 501 and 502 equal distance 525.This causes the cloth waste material of generation or the length 530 of refuse to equal double length 525 between adjacent patterns on band material 12, and these must cut away and abandon.Correspondingly, this needs pattern to extend to the cutting upstream and downstream end of material piece.This just can not produce the material piece that pattern leaves material piece end, makes the pattern curve of different eedle bar sewing start and stop at identical point.And, the noose stitching of the lateral alignment of the eedle sewing of different eedle bars or the unknown.In addition, the combination of the equipment and process of prior art still can not make the curve of two patterns of quilting material piece start and stop alignment and more closely be separated from each other on identical material piece, as shown in Figure 9.
According to one embodiment of present invention, the pattern shown in Fig. 9 obtains on improved multi-needle quilter.The limitation of this pattern is that the repeat length 507 of pattern 501 is basic identical with the repeat length 508 of pattern 502.In this embodiment, multi-needle quilter, for example disclose in U.S. Patent No. 5154130, there is automatic retraction or select eedle, thereby eedle can, and another eedle is sewed.In addition, this multi-needle quilter makes band material 12 with respect to the eedle bar or that the relative motion of bridge section of sewing head is housed is reverse.Although the method for explaining here is the machine fixing with respect to the machine stands longitudinal for sewing head, band material 12 is vertically travelled forward, and at least short distance is moved backward, but these explain also be applicable to sewing head in bridge section by array fixing machine, make sewing head with respect to vertically motion together of cloth.The diagram of the method is referring to Fig. 9 B-9I.
Referring to Fig. 9 B, band material 12 advances through the quilting station along the direction of arrow 531, and the quilting station has the eedle strip array 532 that comprises upstream eedle bar 533 and downstream eedle bar 534.Eedle bar 533 and open fixing distance 525 in 534 minutes.The eedle sewing pattern curve 503 of upstream eedle bar 533 is by the 523 sewing noose stitching sequences 517 in the eedle position.When band material 12 advances a distance 525, as shown in Fig. 9 C, the eedle of downstream bar 534 starts and passes through in the eedle position 521 sewing noose stitching sequences 517 and starts sewing pattern curves 504, thereby is starting to locate starting position that identical lengthwise position the aligns curve 504 that starts to sew with curve 503.Then, along with two eedle bars 533 and 534 sew curve 503 and 504 simultaneously, band material 12 is advanced further, until the ，Ci position, position of Fig. 9 D sewing noose stitching sequence 518, cut off line and inactive bar 533 in position 523 eedle.Then continue sewing, make the position 521 of eedle at bar 534, until the band material is in the position shown in Fig. 9 E.In this position of band material 12, the eedle of bar 534 sewing noose stitching sequence 518, then cut off the eedle of line and inactive bar 534, finishing patterns 501 thus.
Now machine is prepared sewing pattern 502, but band material 12 has been crossed upstream bar 533, must a slow astern distance 525 arrive the position shown in Fig. 9 F, thereby can be by the sequence sewing pattern 502 of the described sewing pattern 501 of contact Fig. 9 B-9E above being similar to.For sewing pattern 502, the eedle in the position 528 of bar 534 starts, and sewing noose stitching sequence 517 starts curves 505, wherein along with band material 12 distance 525 of advancing starts sewing.Like this, at distance 510 places of distance pattern 501 ends, start pattern 502, there is no the cloth waste.Then, when in position shown in Fig. 9 G, the eedle of the position 526 on bar 534 starts, and sewing noose stitching sequence 517 starts curve 506.Then, in two eedle bars 533 and 534 sew curve 503 and 504 o'clock simultaneously, band material 12 is advanced further, until arrive ，Ci position, the position sewing noose stitching sequence 518 of Fig. 9 H, cuts off the eedle of position 528 on line and inactive bar 533.Then continue sewing, the position 526 of eedle in bar 534, reach position shown in Fig. 9 I until band is expected.In this position of band material 12, the eedle of bar 534 sewing noose stitching sequence 518, then cut off the eedle of line and inactive bar 534, and finishing patterns 502 thus.If near pattern 502 another patterns 501 or 502 of sewing that complete, the necessary distance of back leg 525 of band material 12 arrives the beginning of next pattern.
Because eedle bar 533 moves together with 534, when the noose stitching sequence 518 of the noose stitching sequence 517 of construction drawing 9C and 9G and Fig. 9 D and 9H, start other eedle, result will be with these other eedles in the curve of the being sewed noose stitching sequence of sewing midway.This may be unwanted aspect aesthetic view point.As a kind of selection, these eedles can be in the situation that do not cut off line and stop using, and this will cause not wishing that the line occurred processes problem, causes the line order loose or miss stitching.Based on these and other reason, preferably, there is the sewing pattern combination of pattern shown in Fig. 9 501 and 502 character with quilting machines 10 preforms, as described below with reference to Fig. 9 J-9N.
Use above-mentioned quilting machines 10 simplyr to combine with the pattern 501 shown in Fig. 9 and 502 of sewing more neatly.Fig. 9 J means bridge section 21 and the 22 any original positions at its stroke range middle part of quilting machines 10, and enough height on frame allows certain for down stroke.When the curve 503 of pattern 501 starts to locate, can start sewing when the eedle of the lower bridge section 21 of sewing noose stitching sequence 517.Then, lower bridge section 21 curve 503 that starts to sew moves downward simultaneously, and band material 12 is static, and upper bridge section 22 moves upward to identical starting position, arrives position shown in Fig. 9 K.This action can be followed or replace with band material 12 and move upward.When in original position, the eedle of upper bridge section 22 then starts place's sewing noose stitching sequence 518 at curve 504.Because the sewing head of bridge section 21 and 22 can independent operation, so noose stitching sequence 518 can be by 22 sewing of upper bridge section, with continue to sew the incessantly normal stitching of curve 503 of bridge section 21 at present.In addition, the distance that lower bridge section 21 moves downward can be any distance in its stroke range, makes bridge section 22 have enough gaps in original position.By moving downward a complete pattern cycle 513, for example, use the above-mentioned method that reduces the distortion of band material, the curves 503 and 504 of can sewing with the bridge section 21 and 22 of opposite direction transverse shifting.
Then, in bridge section 21 and 22 vertical when static, band material 12 moves upward, and curve 503 and 504 is sewn into pattern to be finished, as Fig. 9 M.In the process that arrives this state, the position shown in band material 12 process Fig. 9 L, the now end of arrival curve 503, and bridge section 21 sewing noose stitching sequences 518.When carrying out this noose stitching sequence, band material 12 can continuous motion, and bridge section 22 sewing curves 504 and not interrupting, and bridge section 21 carries out other horizontal and vertical movement.
After pattern 501 finishes, as shown in Fig. 9 M, band material 12 stops, and bridge section 21 and 22 moves upward, until bridge section is in the identical original position shown in Fig. 9 J.Then, start or stop as required needle head, prepare the new pattern of sewing.In this case, start 3 middle sewing heads, between each of each 4 stature in starting for sewing pattern 501, thus all 7 stature sewing patterns 502.Then, carry out the sewing of pattern 502 according to the basic mode identical with sewing pattern 501.
In addition, for quilting machines 10, advance immediately after the curve 503 that finishes pattern 501 curve 505 of beginning sewing pattern 502 of lower bridge section 21, or even upper bridge section 22 is still at the curve 504 of sewing pattern 501.This is illustrated in Fig. 9 N.When two bridge sections sew different pattern, the controller 19 of quilting machines 10 is controlled the motion of bridge sections, and the mode of the motion of band material and sewing head driving is the stitching density that keeps sequencing, and for example, the curve for two bridge sections sewing, be typically 7 stitchings of per inch.Usually this is by keeping a bridge section vertically static, and the band material, with the sewing velocity sewing of head to fix of fixed speed motion or static bridge section, completes compensating motion by the sewing head of controlling in other bridge section and other bridge section simultaneously.
Described Fig. 9-9M although contacted continuous, unidirectional pattern, this is also more clearly to explain some feature and principle.These features and principle can be applied to other pattern characteristics, those that for example describe with reference to figure 7-7G.May comprise two-way situation about vertically moving for those patterns, the Method And Principle of Fig. 9-9M can be identical purely vertically the moving forwards or backwards with respect to other pattern or pattern characteristics.
The cutting of material piece can be synchronizeed with quilting.When on band material length, from band material 12, laterally the point of cutting material piece arrives cutting-blade head 72, band material conveying roller 18 stops band material 12 and is cut.Sewing can be proceeded, and by band material, is not moved upward and replace with bridge section and move downward and interrupt.This is controlled by controller 19, the sewing that the band material 12 that roller 18 drivings are advanced is carried out than bridge section is moved upward is faster, therefore bridge section is enough the highest more than upper/lower positions at it, thereby, in the cutting operation process when the band material stops, allowing bridge section to sew downwards.
While using different eedles combination sewing different pattern between difference material piece, or during by the different piece of different eedles combination material to be sewn pieces, controller can be controlled eedle and moves or stop.
