Description
Technical field
The present invention relates to a kind of device for laying unidirectional layer on two longitudinal conveyer belts and multiaxis to braiding machine.
Background technology
Such as known from DE10049280A1 and describe in detail by means of Fig. 4 and 4a in the literature according to claim 1 device as described in the preamble.In addition, yarn a group by a group (gruppenweise) moves with the form of yarn beam transverse reciprocating between two longitudinal conveyer belts, in addition, is also like this when arriving each longitudinal conveyer belt in return region.Definition " transverse direction " represents direction that is vertical with the direction of longitudinal conveyer belt or that tilt herein.Therefore, yarn beam mutually lies low with parallel direction a group by a group and lays, in return region, implement transverse motion.
In the embodiment of Fig. 4 and 4a according to DE10049280A1, transverse motion (Versatzbewegung) also implemented by thread-carrier.If thread-carrier arrives each longitudinal conveyer belt and is delivered to by the yarn of yarn beam on the stay hook of longitudinal conveyer belt, then the motion contrary with the throughput direction of longitudinal conveyer belt implemented by this thread-carrier, until the yarn beam be positioned at outside stay hook arrives the idle stay hook of next group.Back yarn guider start its in the opposite direction lay motion.Utilize the weft patterns (Schussmusterung) that can realize the unidirectional ply that each lays according to the device of DE10049280A1, namely in the longitudinal direction of the unidirectional ply produced, the quantity of the weft yarn laid can be different, thus also produces a group by a group or single space (L ü cken).Arrange on longitudinal conveyer belt in the embodiment of Fig. 4 and 4a according to DE10049280A1 two hooks extended parallel to each other are arranged and can realize this object with higher quality.Therefore, the thread-carrier implementing transverse motion not only must be parallel to longitudinal conveyer belt but also must move transverse to longitudinal conveyer belt, and also necessary successively twice decline in addition, be namely directed into and lay near plane.The stretch journey (Teilstrecke) of laying track is implemented in the position that feeler must decline at it.In addition, if yarn beam is passed on idle stay hook on direction from outside to inside, then extra hold down gag is also needed.
Therefore, must boot up three orthogonal sides and control thread-carrier in the embodiment of Fig. 4 and 4a according to DE10049280A1 to lay smooth unidirectional ply, need hold down gag in addition.What yarn was arranged to two hooks lays the restriction also brought in the size design of whole device.Generally speaking structural expend very high.
Therefore in DE10048280A1, also describe by means of Fig. 3 and 3a the possibility belonging to prior art, implement transverse motion by means of special traversing comb frame (Versatzrechen).The principle of traversing comb frame is such as known from DE3641640C1.In addition, importantly the function distinguishing between motion and transverse motion is being laid.In the end laying track, thread-carrier sails out of through its longitudinal conveyer belt arranged, and traversing comb frame synchronously and move on the throughput direction of longitudinal conveyer belt with the phase place identical with longitudinal conveyer belt.In addition, the stay hook guiding the yarn come to pass longitudinal conveyer belt guides and is received by the stay hook of traversing comb frame.Then traversing comb frame moves upward to its traversing position in the side contrary with the throughput direction of longitudinal conveyer belt, and this traversing comb frame carries yarn simultaneously.Meanwhile, thread-carrier can carry out it towards the drawback movement of opposed longitudinal conveyer belt and at this moment will be arranged in the yarn of traversing comb frame at its side tractive.Traversing comb frame is finally turned round its direction of motion and again synchronous with longitudinal conveyer belt and with so a kind of phase place relative to longitudinal conveyer belt, and the yarn namely pulled out by thread-carrier is derived from the stay hook of traversing comb frame and received by the stay hook be positioned at longitudinal conveyer belt.
For a long time, known traversing comb frame is proved to be feasible in practice.In addition, what be worth improvement is transition stage: if yarn beam is given the stay hook of carrier chain by thread-carrier, single yarn may be torn.This can adversely cause forming fault (Gassenbildung) in the fringe region of the unidirectional ply produced.More critical is inwardly returned to idle stay hook from traversing comb frame by yarn.Because the stress of yarn can be different, then yarn also can unevenly from the landing of traversing comb frame.Avulsed danger on the stay hook having carrier chain in addition.Thereby produce the danger of larger formation fault, this can greatly disturb when knitting (Verwirken) and the quality of the unidirectional layer of final production can decline.
The device with gantry structure is utilized to lay unidirectional ply according to DE19726831C2.Here traverse the portal jib crane reversion on the sidepiece of machine frame extended above longitudinal conveyer belt to sail.Portal jib crane has the thread-carrier being designed to derrick car form, and it can travel in the longitudinal direction of portal jib crane.In addition, thread-carrier also can travel perpendicular on the direction laying plane on third direction, namely.If the precise control ground of the different motion conditions of thread-carrier and device is mutually harmonious, then deposit a large amount of variedly by possibility that yarn beam or single yarn stress are compatibly laid between longitudinal conveyer belt.In DE19726831C2, also there is brief prompting, namely traversing comb frame can be installed to portal jib crane (" horizontal gantry bogey ") and go up and therewith move.Do not provide details, affiliated accompanying drawing also schematically shows.
Summary of the invention
Therefore the object of the invention is to, the device that a kind of article starts the type first mentioned is proposed, utilize this device when do not have extra structural expend reliably implement transverse motion with higher speed, and can not damage or the yarn of tensioning yarn beam unevenly, thus avoid the formation of harmful fault.
Object of the present invention is realized by the such device with the feature of claim 1.
In a device in accordance with the invention, utilize thread-carrier itself to implement transverse motion as beforely.In addition, this thread-carrier is by compressing the support of comb frame, and this compression comb frame is synchronized with the movement with thread-carrier during transverse motion.Here, compressing comb frame can with the first component motion motion, and this component motion can according to controlling to remove near the stay hook compressing comb frame and be directed to longitudinal conveyer belt or from longitudinal conveyer belt.The second component motion compressing comb frame is parallel to the cross moving track extension of thread-carrier.Compress comb frame and there is teeth portion, compress comb frame utilize this teeth portion can nip the yarn beam extended near stay hook row in outside yarn between; Due to compress comb frame from top nip yarn beam yarn between, compress comb frame and yarn remained on and lays in the less interval of plane, and therefore make yarn no longer skid off from the stay hook of longitudinal conveyer belt during transverse motion.If the stay hook that next group is left unused arrives longitudinal conveyer belt, then thread-carrier carries out laying motion towards opposed longitudinal conveyer belt with contrary direction, makes yarn slide from the teeth portion compressing comb frame and be delivered to the stay hook of longitudinal conveyer belt thus.
Advantage according to device of the present invention is, thread-carrier not only can be retained in same plane of movement all the time laying on track but also on cross moving track; No longer need of short duration sinking.Equally also be enough to provide unique plane of movement for compressing comb frame.Although two component motions compressing comb frame are arranged in a plane, just the yarn after the stay hook being positioned at longitudinal conveyer belt can be transported to by means of only the motion in the first component motion and lay near plane and reliably to remain on after stay hook.
According to the first optional improvement project, the plane of movement of thread-carrier and compression comb frame can extend in parallel to each other.If but the tracks compressing comb frame extends at plane of movement slightly intilted to the direction laying plane, then achieve special effect.Moving downward of teeth portion also contributes to reliably being compressed by the yarn line segment be positioned at after stay hook and keeping in this embodiment.
According to the improvement project that another is favourable, the yarn outlet of thread-carrier has reed (Riet).The yarn realizing leaving thread-carrier thus overcomes the orderly guiding of fault.
In addition, when the high requirement for unidirectional ply quality and when not too thick yarn advantageously, the distribution of the distribution of opening and the stay (Stege) of reed and the stay hook on longitudinal conveyer belt and consistent in the distribution compressing the teeth portion on comb frame.But this measurement not necessarily.
In addition, a kind of favourable improvement project according to device of the present invention is also, arranges hold down gag in the both sides of thread-carrier along reed, and it can roll away from or be drawn into according to the position of the switch on the direction laying plane.Once thread-carrier traverses above the stay hook of the longitudinal conveyer belt arrived, then this type of hold down gag can be rolled away from momently and yarn beam declining to the direction laying plane below at stay hook.To nip yarn beam once compress comb frame, then hold down gag is exactly unnecessary and can be again drawn into.
Particularly advantageously, apparatus design according to the present invention has gantry system for supplying yarn.In addition, be movably fixed on Buddhism crane if compress comb frame, then it only moves just enough relative to compression comb frame in its first component motion.In the same circumstances, the second component motion is provided by portal jib crane self.
Optionally, also compression comb frame movably can be arranged in frame.Also can consider to be arranged on thread-carrier.Other favourable design provides in other dependent claims.Owing to compressing comb frame (can be orthogonal but also can be bending closing) track in principle all the time through closing, then can utilize the part of rotation rapidly and change in nyctitropic gentle transition at needs and design motion process preferably.
The invention still further relates to one according to claim 18 multiaxis as described in the preamble to braiding machine.This type of multiaxis belongs to prior art to braiding machine, see such as DE19726831C2.In addition, before and after on the traffic direction of longitudinal conveyer belt, multiple supply station corresponding respectively to a unidirectional layer is set.
Multiaxis according to the present invention is to the structure of braiding machine, and at least one supply station is designed with according to the device according to any one of claim 1 to 17.

Detailed description of the invention
The multiaxis schematically shown in Fig. 1 is utilized to produce with the multiaxis of the form of the band be made up of two unidirectional layers to yarn fabric to braiding machine.This multiaxis has with the frame of two spaced sidepiece 1 compositions to braiding machine and extends in the longitudinal direction of tape yams fabric to be produced.With the longitudinal conveyer belt 3 circulated that is mutually horizontally arranged at interval two in frame 1, its commutate on reversing shaft 26 and by be arranged in docking station 22, sightless drive unit drives.Longitudinal conveyer belt 3 moves on traffic direction 5.Longitudinal conveyer belt 3 is with the form design of carrier chain in an example shown, and this carrier chain has common stay hook 4, the detail view shown in amplifying see lower right in Fig. 1.Unique row's stay hook 4 is only set in an example shown on each longitudinal conveyer belt 3; But known can also arrange two row or multi-row stay hook 4 for each longitudinal conveyer belt 3.
Two longitudinal conveyer belts 3 define and lay plane, lay in plane lay single unidirectional layer at this.Two unidirectional layers 17 and 18 are laid in selected embodiment.Wherein the first unidirectional layer 17 is with extending longitudinally towards the extending longitudinally of frame and therefore also towards the multiaxis produced to yarn fabric of 45° angle.Second unidirectional layer 18 is equally with extending longitudinally towards frame of 45° angle, but contrary with the direction of the first thread layers 17.
In order to lay two unidirectional layers 17,18, arrange two supply stations 20,21 before and after in the longitudinal direction of frame, the structure of these two supply stations is identical.Need the yarn of the yarn beam 13 of laying is extracted from creel 23; Intermediate storage mean equally also can be used as yarn storehouse.Yarn runs to and is laying with fixing motor pattern the thread-carrier 9 moved in the plane of movement above plane, and yarn beam 13 is alternately delivered on the stay hook 4 of longitudinal conveyer belt 3 by this thread-carrier on the path that circulation is laid.Realize two in this way with the unidirectional layer 17,18 of the plane form be made up of the yarn extended in parallel.
Supply station 20,21 is designed with according to the device for laying unidirectional ply of the present invention.Also will be described these devices in more detail hereinafter.At supply station, below common docking station 22 is set, in this docking station, fixes single unidirectional ply 17,18 stackedly, as by knitting or stitching devices, as from longitudinal seam 19.This connection also can be realized by flattener or dual-band extruder.Then can be wound up on cylinder as the processing of blank for other.Other station Reference numeral 24 represents.
Gantry system of laying according to having portal jib crane 6 of yarn realizes.In the moving region of portal jib crane 6, on the upper side of sidepiece 1, there is tooth bar 2, utilize this rack position to control the motion of portal jib crane 6 exactly.Therefore portal jib crane 6 has gear 7, in its engaging-in tooth bar 2.The cross section that the device in the region of the first or second supply station 20,21 extends perpendicular to the elongation of frame can be observed particularly well from Fig. 2.Be used as the riding roller of portal jib crane 6 according to the embodiment middle gear 7 of Fig. 2 simultaneously.But also special riding roller can be set and gear 7 only for controlling the position of portal jib crane 6 exactly.The traffic direction replaced of portal jib crane 6 is illustrated by double-head arrow 8.
In each in the supply station 20,21 of two same configuration, portal jib crane 6 has the form of bridge shape support, and it is supported on the sidepiece 1 of frame and transverse to the sidepiece of frame with its end and extends.In addition, " transverse direction " can represent " perpendicular to sidepiece 1 ", also can represent " oblique in sidepiece 1 ".On portal jib crane 6, thread-carrier 9 can be sailed in the reversion that comes up of the longitudinal direction of portal jib crane.The traffic direction of thread-carrier on portal jib crane 6 is represented by double-head arrow 10 in Fig. 1 to 3.The unshowned unique motor that is driven through of portal jib crane 6 and thread-carrier 9 realizes.The motion of longitudinal conveyer belt 3, portal jib crane 6 and thread-carrier 9 must be mutually harmonious exactly by the control of device.
Thread-carrier 9 in the end regions of laid processes, in outward direction exceed longitudinal conveyer belt 3 after implement transverse motion, namely contrary with the traffic direction 5 of longitudinal conveyer belt 3 motion, until the yarn being positioned at the yarn beam 13 on the lateral surface of stay hook 4 again arrives the idle stay hook 4 of next group and is delivered on it.Here, thread-carrier 9 describes and is laying the tracks closed on the plane of movement extended above plane.This tracks lays track by two and two cross moving tracks combine.Lay track to extend transverse to longitudinal conveyer belt 3, wherein, " transverse direction " here comprises " oblique in sidepiece 1 " and therefore comprise " oblique in longitudinal conveyer belt 3 ".Two are laid parallel track and extend in longitudinal conveyer belt 3, exactly, extend near the row of stay hook 4 in outside.Therefore, the tracks of thread-carrier 9 describes out the uninterrupted large X represented in single deployment cycle, or is similar to shape or the Roman number X of 8.The motion on portal jib crane 6 is simultaneously and mutually coordinate to realize by the motion of portal jib crane 6 on the sidepiece 1 of machine frame and thread-carrier 9 to lay the oblique operation of track between longitudinal conveyer belt 3.
Yarn beam 13 is left thread-carrier 9 in below through reed 12 and is commutated immediately.In some cases advantageously, perforate is consistent with the distribution of stay hook 4 on longitudinal conveyer belt 3 with the distribution of the reed stay of reed 12; But this measurement not necessarily.Be positioned at reed 12 on thread-carrier 9 and laying moving on rails all the time above the plane of the highest jut through stay hook 4.If thread-carrier 9 has exceeded the row of stay hook 4 when outside motion, then yarn beam 13 must have been reduced, make thus its yarn arrive safely stay hook 4 below or hooked by stay hook.
Hold down gag 11a, 11b are set on thread-carrier 9 for this reason.Fig. 4 illustrates the first embodiment of hold down gag 11a.At the hold down gag 11a arranging a slab near the left side of reed 12 and right side respectively on the traffic direction 10 of thread-carrier 9.It has the profile (Fig. 4) of corner fittings form, and its length extends and exceeds this overall length, see Figure 10 and 11 in the overall length of reed 12.Two hold down gag 11a to be movably fixed on thread-carrier 9 perpendicular to the plane of movement of thread-carrier and by the control of device from idle (mentioning) position transfer to (decline) position of work.In its operating position, hold down gag 11a is directed into and lays near plane.
In the diagram of Fig. 4, the hold down gag 11a on the right is arranged in idle position, and the hold down gag 11a on the left side is arranged in the position of its work in the figure.Obviously visible, the yarn of yarn beam 13 to be lowered by the stiff end of stay hook 4, i.e. so-called needle-bar (Nadelbett) 30 and be positioned at safely thus stay hook after or the hook that is fixed hook.Hold down gag 11a pneumatically or electromagnetically operates and implement rectilinear motion alternately time.
Illustrate another kind of embodiment in figs. 5 and 6.Herein, thread-carrier 9 has and swingable goes out oral 25.The longitudinal axis that its swinging axle 27 is parallel to reed 12 extends.Going out the hold down gag 11b and reed 12 on oral 25 with the lath-shaped that rigidity is located thereon.In order to bring in its operating position by hold down gag 11b, oral 25 will be gone out at thread-carrier 9 upper offset, thus relevant hold down gag 11b is directed to lays near plane, see Fig. 6.Its effect is the same with at the embodiment according to Fig. 4.All there is following advantage in any situation, namely need not implement extra perpendicular to the motion of laying plane by whole thread-carrier 9, and be only there is less weight and therefore lighter governor motion needs fast and accurately to move and control.
Portal jib crane 6 is each in the region of its end forms a housing 14, and this housing holds its gear 7.In addition, in each housing 14, compressing comb frame 15 is movably bearing on holding device 28, see Fig. 2 and 3.Each compression comb frame has dull and stereotyped shape, has teeth portion 16 thereon.Teeth portion 16 is towards the stay hook 4 on longitudinal conveyer belt 3.Compress in the diagram of Fig. 4 to 9 comb frame 15 be parallel to lay plane and with and lay in plane that the less interval of plane extends and move.The plane of movement compressing comb frame 15 also can extend on the direction laying plane to inherence slightly down, as in the diagram by shown in straight line 33.If the plane of movement compressing comb frame 15 is tilt corresponding to straight line 33, then compress the function that comb frame 15 also performs hold down gag.Yarn beam 13 can be remained on after stay hook 4 safely thus.Therefore, hold down gag 11a, 11b can design less as the case may be or design with less stroke, even can fully phase out hold down gag in some cases.
Compress comb frame 15 and its mirror image equally designs because all have in the both sides of device, only describe by means of Fig. 4 to 13 function that one of them compresses comb frame 15 below.To this, Fig. 4 to 9 illustrates the sectional view of longitudinal conveyer belt 3 perpendicular to its longitudinal direction, wherein, illustrates the different motion stage of the workpiece during traversing process.Figure 10 to 13 is the views being attached to Fig. 7 to 9 from top view; It corresponds to the sectional view near the thread-carrier 9 above reed 12 observed downwards, wherein, can observe reed 12 and the part be positioned at below thread-carrier 9 of visual means from inside.In addition, in Figure 10 to 13, utilize Reference numeral 31 to amplify the single yarn illustrating yarn beam 13.
Be arranged on outside the stay hook 4 be positioned on longitudinal conveyer belt 3 in the region of longitudinal conveyer belt 3 of compression comb frame 15 belonging to it.Compression comb frame 15 can be made to occupy outside position or occupy inside position by means of driving and control device.Fig. 4 to 6 and 10 illustrates outside position, and in Fig. 7 to 9 and 11 to 13, illustrate inside position.Compress comb frame 15 in from an evolution to the process of another position to move in its first component motion; It extends on the direction of double-head arrow 29, namely perpendicular to the direction of longitudinal conveyer belt, see Figure 10.In the position that it is outside (Figure 10), compress comb frame 15 hook 4 that is obviously fixed and outwards remove; In inside position, the teeth portion of (Figure 11 to 13) stay hook 4 and compression comb frame 15 closely opposes mutually with less interval.
During thread-carrier 9 transverse motion, compress comb frame 15 and occupy its inside position; Then contrary during the laid processes that thread-carrier 9 moves between longitudinal conveyer belt 3, compress comb frame 15 and be arranged in its outside position.The following describes and how to launch transverse motion when using and compressing comb frame 15.
Thread-carrier 9 traverses above the stay hook 4 of the longitudinal conveyer belt 3 arrived in the end laying track; In addition, hold down gag 11a, 11b are arranged in the position of its inoperative and compress comb frame 15 and be arranged in its outside position, see Fig. 5 and 10.Following hold down gag 11a, 11b drive in its operating position, and compress comb frame 15 and be first also retained in its outside position; This state illustrates in figs. 4 and 6 and yet relates to Figure 10.From Fig. 4,6 and 7 obviously, the yarn of yarn beam 13 in the anchor portion of stay hook 4, namely, so-called needle-bar 30 is removed from stay hook 4 with subregion 13a.
In order to traversing process can be implemented in an orderly manner, in the next step compression comb frame 15 to be brought in its inside position and therefore and then hold down gag 11a, 11b to be returned in its idle position, see Fig. 7 and the transition portion to Fig. 8 in order to harmonious.This transition portion is also visible in fig. 11.In the process being transitioned into its inside position, between the yarn compressing the engaging-in yarn beam 13 extended near stay hook 4 in outside of the teeth portion 16 of comb frame 15.In addition, this structure so realizes, and the teeth portion 16 compressing comb frame 15 acts on the yarn of yarn beam 13 from above, namely act on hold down gag equally in this sense.Result causes being positioned at below the region of the needle-bar 30 on stay hook 4 according to the yarn of Fig. 8 yarn beam 13; The subregion 13a stretched out disappears.It is desirable that the yarn beam 13 of newly laying also can to abut in yarn beam 13 that existed, that be arranged on stay hook 4 and be present in stay hook 4 more above region.
Transverse motion is implemented in position relative to longitudinal conveyer belt 3 at compression comb frame 15 as seen from Figure 8 and thread-carrier 9.Because this transverse motion is implemented by means of portal jib crane 6, thread-carrier 9 and the synchronous operation of compression comb frame 15, exactly, perpendicular to drawing plane and away from observer in the diagram of Fig. 8.In contrast, longitudinal conveyer belt 3 perpendicular to drawing plane towards motion of an observer.Therefore the expansion of transverse motion is no longer described in fig. 8.But its to observe from above in the diagram according to Figure 11 to 13 obviously visible.Mention, the single yarn 31 amplifying the yarn beam 13 illustrated to a great extent can be such as the yarn of the leftmost side of the yarn beam of conveying in the accompanying drawings.The teeth portion 16 in four outsides of its compacted comb frame 15 covers and lays width traction along the total of stay hook 4, until it arrives the first idle stay hook 4.In addition, it remains on after the stay hook 4 that existed all the time safely, because it is pressed downward tightly by the teeth portion 16 compressing comb frame 15.
If reach the hook that next lays the corresponding idle leftmost side of width, then thread-carrier 9 carries out its next laid processes on portal jib crane 6.Therefore it traverses to inherence above the row of stay hook 4 on the direction of opposed longitudinal conveyer belt 3.The yarn of yarn beam 13 skids off from the teeth portion 16 compressing comb frame 15 and slides between idle stay hook 4 thus, and see Fig. 9, wherein, thread-carrier 9 is to left movement.Because during laid processes, portal jib crane 6 returns in its original position, compresses comb frame 15 and also turns back to together with portal jib crane in frame in its original position, in addition, compresses comb frame and again occupies its outside position.Therefore, comb frame 15 has similarly illustrated the basic configuration of rectangle in any deployment cycle tracks closed relative to frame is compressed.This rectangle also can have the angle of rounding, is changing into occluded ellipse, ellipsoid or realizes distortion according to the control (wherein depending on higher speed) how realizing compressing comb frame 15 practically.When thread-carrier 9 and portal jib crane 6 arrive opposed longitudinal conveyer belt 3, there is foregoing same precondition.This process can carry out repetition in the same manner.
Must remind, by means of drawings merely depict an embodiment.Compress comb frame 15 to be still parallel to the direction motion of longitudinal conveyer belt 3 and to be placed in its fixture by this way.Therefore, the second component motion that its tracks being parallel to thread-carrier 9 extends need not under any circumstance all be applied by portal jib crane 6.This is such as this situation, namely compresses comb frame 15 and is installed on frame or thread-carrier 9.
Compress in accompanying drawing above comb frame 15 all the time be designed to pin that straight line stretches and illustrate compressing together with teeth portion 16 that the direction of the first component motion of comb frame 15 is run.But can be also advantageously another kind of profile of tooth according to single situation.Figure 14 illustrates a kind of like this profile of tooth of change, particularly see the subregion irised out.According to diagram, teeth portion has the shape of plain hook 32.Plain hook is positioned on the plane of motion of compression comb frame 15.In addition, dog hole 32a is designed to the grasping holes of the yarn of yarn beam 13.If compressing comb frame 15 is directed near the row of stay hook 4 with its first component motion, then the extra side that hook 32 also performs on the yarn of yarn beam 13 with its dog hole 32a captures motion.Here, moving downward in its plane of movement surface thereof when shifting to stay hook 4 if compress comb frame 15, as illustrated by means of Fig. 4 (see Reference numeral 33), then enhancing and capture and keep effect.
