Description
Technical field
The present invention relates to a kind of device that is used on two vertical conveyer belts, laying unidirectional layer and multiaxis to braiding machine.
Background technology
According to claim 1 device as described in the preamble such as known from DE10049280A1 and describe in detail by means of Fig. 4 and 4a in the literature.In addition, one group one group ground of yarn (gruppenweise) laterally moves around between two vertical conveyer belts with the form of yarn beam, in addition, also is like this in the zone of turning back when arriving each vertical conveyer belt.Direction vertical with the direction of vertical conveyer belt or that tilt is represented in definition " laterally " herein.Therefore, one group one group ground of yarn beam lies low mutually with parallel direction and lays, and implements transverse motion in the zone of turning back.
In the embodiment according to the Fig. 4 of DE10049280A1 and 4a, thread-carrier is also implemented transverse motion (Versatzbewegung).If thread-carrier arrives each vertical conveyer belt and the yarn of yarn beam is delivered on the stay hook of vertical conveyer belt, then this thread-carrier is implemented and the vertically opposite motion of throughput direction of conveyer belt, arrives the idle stay hook of next group up to the yarn beam that is positioned at outside the stay hook.Afterwards thread-carrier begin its in the opposite direction lay motion.Utilization can realize the weft patterns (Schussmusterung) of the unidirectional ply that each lays according to the device of DE10049280A1, promptly the unidirectional ply that produces vertically on, the quantity of the weft yarn that lays can be different, thereby also produces one group of space one group or single (L ü cken).In according to the embodiment of the Fig. 4 of DE10049280A1 and 4a, on vertical conveyer belt, be provided with under two hook rows' of extending of being parallel to each other the situation and can realizing this purpose with higher quality.Therefore, the thread-carrier of enforcement transverse motion not only must be parallel to vertical conveyer belt but also must move transverse to vertical conveyer belt, and also twice decline successively in addition, promptly is directed into and lays near the plane.Feeler must implement to lay the stretch journey (Teilstrecke) of track in the position of its decline.In addition, if yarn beam is being passed on the direction from outside to inside on the idle stay hook, then also need extra hold down gag.
Therefore, for lay smooth unidirectional ply must be in according to the embodiment of the Fig. 4 of DE10049280A1 and 4a on three orthogonal directions guiding and control thread-carrier, need hold down gag in addition.Yarn has also brought restriction in whole device size design to laying of two hooks row.Generally speaking structural expend very high.
Therefore in DE10048280A1, also described the possibility that belongs to prior art, implemented transverse motion by means of special traversing comb formula frame (Versatzrechen) by means of Fig. 3 and 3a.The principle of traversing comb formula frame is such as known from DE3641640C1.In addition, importantly at the function distinguishing that lays between motion and the transverse motion.In the end of laying track, thread-carrier sails out of through vertical conveyer belt that it set, and traversing comb formula frame synchronously and with the phase place identical with vertical conveyer belt moves on the throughput direction of vertical conveyer belt.In addition, the next yarn of guiding passes the stay hook guiding of vertical conveyer belt and is received by the stay hook of traversing comb formula frame.Traversing then comb formula frame moves to its traversing position on the direction opposite with the throughput direction of vertical conveyer belt, this traversing comb formula frame carries yarn simultaneously.Meanwhile, thread-carrier can carry out it towards the drawback movement of opposed vertical conveyer belt and at this moment will be arranged in the yarn of traversing comb formula frame at one side tractive.Traversing comb formula frame turn round at last its direction of motion and once more with vertical conveyer belt synchronously and with a kind of like this phase place with respect to vertical conveyer belt, promptly the yarn of being pulled out by thread-carrier is derived and the stay hook that is positioned on vertical conveyer belt receives from the stay hook of traversing comb formula frame.
For a long time, known traversing comb formula frame is proved to be feasible in practice.In addition, what be worth to improve is transition stage: if yarn beam is given the stay hook of carrier chain by thread-carrier, single yarn may be torn.This can cause forming fault (Gassenbildung) unfriendly in the fringe region of the unidirectional ply that produces.More critical is that yarn is inwardly returned to idle stay hook from traversing comb formula frame.Because the stress of yarn can be different, then yarn also can be unevenly from the landing of traversing comb formula frame.Have avulsed danger on the stay hook of carrier chain in addition.Produced the danger of bigger formation fault thus, this can disturb when knitting (Verwirken) greatly and the quality of the unidirectional layer of final production can descend.
Utilize device to lay unidirectional ply according to DE19726831C2 with gantry structure.Here traversing on the sidepiece of portal jib crane at machine frame that extends in vertical conveyer belt top reversion sails.On portal jib crane, have the thread-carrier that is designed to the derrick car form, its can portal jib crane vertically on travel.In addition, thread-carrier also can travel on the third direction, promptly perpendicular to the direction of laying the plane.If the precise control of the different motion conditions of thread-carrier and device ground is harmonious mutually, then deposit a large amount of possibilities that variedly yarn beam or single yarn stress compatibly are laid between vertical conveyer belt.In DE19726831C2, also have brief prompting, promptly traversing comb formula frame can be installed to portal jib crane (" laterally gantry bogey ") and go up and therewith motion.Do not provide details, affiliated accompanying drawing is also schematically illustrated.
Summary of the invention
Therefore the objective of the invention is to, the device that a kind of article starts the type of at first mentioning is proposed, utilize this device not having to implement transverse motion reliably with higher speed under the extra structural situation about expending, and can not damage or the yarn of tensioning yarn beam unevenly, thereby avoided the formation of harmful fault.
This type of device of the feature of purpose of the present invention by having claim 1 is realized.
In device according to the present invention, utilize thread-carrier itself to implement transverse motion as beforely.In addition, this thread-carrier is by compressing the support of comb formula frame, and this compresses comb formula frame and is synchronized with the movement with thread-carrier during transverse motion.Here, compressing comb formula frame can be with first component motion motion, and this component motion can will compress near the stay hook that comb formula frame is directed to vertical conveyer belt or removes from vertical conveyer belt according to control.Second component motion that compresses comb formula frame is parallel to the cross moving track extension of thread-carrier.Compress comb formula frame and have tooth portion, compress between the yarn of the yarn beam that comb formula frame utilizes this tooth portion can nip externally to extend near stay hook row; Owing to compress between comb formula frame nips the yarn of yarn beam from the top, compress comb formula frame and yarn is remained on and lays in the less interval, plane, and therefore yarn is no longer skidded off during transverse motion from the stay hook of vertical conveyer belt.If the idle stay hook of next group arrives vertical conveyer belt, then thread-carrier lays motion with opposite direction towards opposed vertical conveyer belt, makes yarn slide and be delivered on the stay hook of vertical conveyer belt from the tooth portion that compresses comb formula frame thus.
Advantage according to device of the present invention is that thread-carrier is not only laying on the track but also can be retained in the same plane of movement all the time on cross moving track; No longer need of short duration sinking.Equally also being enough to provides unique plane of movement for compressing comb formula frame.Be arranged in a plane though compress two component motions of comb formula frame, only the yarn that just can will be positioned at the stay hook back of vertical conveyer belt by the motion in first component motion is transported to and lays near the plane and remain on the stay hook back reliably.
According to first kind of optional improvement project, thread-carrier can extend in parallel to each other with the plane of movement that compresses comb formula frame.If yet the tracks that compresses comb formula frame has realized special effect extending to the intilted slightly plane of movement of the direction of laying the plane.The yarn line segment that also helps to be positioned at the stay hook back that moves downward of tooth portion compresses reliably and keeps in this embodiment.
According to another favourable improvement project, the yarn outlet of thread-carrier has reed (Riet).The yarn of realizing leaving thread-carrier thus overcomes the orderly guiding of fault.
In addition, for the high requirement of unidirectional ply quality and under the situation of not too thick yarn advantageously, the distribution of the distribution of opening and the stay of reed (Stege) and stay hook on vertical conveyer belt and to compress the distribution of the tooth portion on the comb formula frame consistent.Yet should weigh not necessarily.
In addition, a kind of favourable improvement project according to device of the present invention is that also along reed hold down gag is set in the both sides of thread-carrier, it can roll away from or be drawn into according to the position of the switch on the direction of laying the plane.In case thread-carrier traverses the stay hook top in the vertical conveyer belt that arrives, then this type of hold down gag can be rolled away from momently and yarn beam descends to the direction of laying the plane in the back of stay hook.In case compress the comb formula frame yarn beam of nipping, then hold down gag is exactly unnecessary and can be drawn into again.
Particularly advantageous is that device design according to the present invention is useful on gantry system that supplies with yarn.In addition, movably be fixed on the Buddhism crane if compress comb formula frame, then it only moves just enough in its first component motion with respect to compressing comb formula frame.Under same case, second component motion is provided by portal jib crane self.
Optionally, also can movably be arranged on the frame compressing comb formula frame.Also can consider it is arranged on the thread-carrier.Other favourable design provides in other dependent claims.Owing to compress comb formula frame in principle all the time through (can be into rectangle but also can be crooked sealing) track of sealing, the part that then can utilize rotation preferably changes design motion process in the mild transition of direction apace and at needs.
The invention still further relates to a kind of according to claim 18 multiaxis as described in the preamble to braiding machine.This type of multiaxis belongs to prior art to braiding machine, referring to such as DE19726831C2.In addition, before and after on the traffic direction of vertical conveyer belt, a plurality of supply stations that correspond respectively to a unidirectional layer are set.

Thread-carrier 9 surpasses in the end regions of laid processes, on outside direction implements transverse motion, the i.e. motion opposite with the traffic direction 5 of vertical conveyer belt 3 after vertical conveyer belt 3, and the yarn of the yarn beam 13 on the lateral surface that is positioned at stay hook 4 arrives the stay hook 4 that next group leaves unused again and is delivered on it.Here, thread-carrier 9 has been described in the tracks of laying the sealing on the plane of movement that extends above the plane.This tracks lays track by two and two cross moving tracks combine.Lay track transverse to vertically conveyer belt 3 extensions, wherein, " laterally " here comprises " oblique in sidepiece 1 " and therefore comprises " oblique in vertical conveyer belt 3 ".Two are laid parallel track in vertical conveyer belt 3 extensions, and exactly, the row in the outside near stay hook 4 extends.Therefore, the tracks of thread-carrier 9 is described out the big X of uninterrupted expression in single deployment cycle, or approximate 8 shape or Roman number X.Lay track in vertically motion while and the coordination realization mutually on portal jib crane 6 of the oblique operation between the conveyer belt 3 by motion on the sidepiece 1 of portal jib crane 6 at machine frame and thread-carrier 9.
Hold down gag 11a, 11b are set on thread-carrier 9 for this reason.Fig. 4 has showed first kind of embodiment of hold down gag 11a.On the traffic direction 10 of thread-carrier 9 near the left side of reed 12 and the hold down gag 11a that the right side is provided with a slab respectively.It has the profile (Fig. 4) of corner fittings form, and its length extends on the length overall of reed 12 and exceed this length overall, referring to Figure 10 and 11.Two hold down gag 11a movably are fixed on the thread-carrier 9 perpendicular to the plane of movement of thread-carrier and control (decline) position from idle (mentioning) position transfer to work by device.In its operating position, hold down gag 11a is directed into and lays near the plane.
The hold down gag 11a on the right is arranged in idle position in the diagrammatic sketch of Fig. 4, and the hold down gag 11a on the left side is arranged in the position of its work in the figure.Obviously as seen, the yarn of yarn beam 13 be lowered by stay hook 4 stiff end, be on the so-called needle-bar (Nadelbett) 30 and be positioned at the back of stay hook safely thus or the hook that is fixed hooks.Hold down gag 11a pneumatically or electromagnetic ground is operated and implement rectilinear motion alternately the time.
In Fig. 5 and 6, showed another kind of embodiment.Herein, thread-carrier 9 have can swing go out oral 25.The longitudinal axis that its swinging axle 27 is parallel to reed 12 extends.Going out hold down gag 11b and the reed 12 that has rigidity position lath-shaped thereon on oral 25.For one among the hold down gag 11b is brought in its operating position, will go out oral 25 at thread-carrier 9 upper offsets, lay near the plane thereby relevant hold down gag 11b is directed to, referring to Fig. 6.Its effect is with the same at the embodiment according to Fig. 4.All have following advantage in any situation, promptly needn't be whole thread-carrier 9 implement extra perpendicular to the motion of laying the plane, and only be have less weight and therefore lighter governor motion remain fast and accurately to move and control.
Portal jib crane 6 respectively forms a housing 14 in the zone of its end, this housing holds its gear 7.In addition, in each housing 14, compress comb formula frame 15 and movably be bearing on the holding device 28, referring to Fig. 2 and 3.Each compresses comb formula frame and has dull and stereotyped shape, has tooth portion 16 thereon.The stay hook 4 of tooth portion 16 on vertical conveyer belt 3.Compressing comb formula frame 15 in the diagrammatic sketch of Fig. 4 to 9 is being parallel to and is laying the plane and to move with laying in the plane of extending at less interval, plane.The plane of movement that compresses comb formula frame 15 also can extend on the direction of laying the plane to the inherence slightly down, as passing through shown in the straight line 33 among Fig. 4.Tilt corresponding to straight line 33 if compress the plane of movement of comb formula frame 15, then compress the function that comb formula frame 15 is also carried out hold down gag.Yarn beam 13 can be remained on safely the back of stay hook 4 thus.Therefore, hold down gag 11a, 11b can design forr a short time as the case may be or design with littler stroke, in some cases even can fully phase out hold down gag.
Because the both sides at device all have the comb of compressing formula frame 15 and its mirror image equally designs, by means of Fig. 4 to 13 function that one of them compresses comb formula frame 15 is only described below.To this, Fig. 4 to 9 has showed that vertical conveyer belt 3 perpendicular to its sectional view longitudinally, wherein, showed the different motion stage of the workpiece during traversing process.Figure 10 to 13 is views that are attached to Fig. 7 to 9 of observing from the top; It wherein, can observe the part that is positioned at thread-carrier 9 belows of reed 12 and visual means internally corresponding to the sectional view of observing downwards near the thread-carrier 9 of reed 12 tops.In addition, in Figure 10 to 13, utilize Reference numeral 31 to amplify the single yarn of having represented yarn beam 13.
Compress in the zone of vertical conveyer belt 3 of comb formula frame 15 under it and be set in place outside the stay hook 4 on vertical conveyer belt 3.By means of driving and control device can make and compresses comb formula frame 15 and occupy outside position or occupy inside position.Fig. 4 to 6 and 10 has showed outside position, and has showed inside position in Fig. 7 to 9 and 11 to 13.Compressing comb formula frame 15 from an evolution to the process of another position moves in its first component motion; It extends on the direction of double-head arrow 29, promptly perpendicular to the vertical direction of conveyer belt, referring to Figure 10.In its outside position (Figure 10), compress comb formula frame 15 hook 4 that obviously is fixed and outwards remove; (Figure 11 to 13) stay hook 4 closely opposes with less interval mutually with the tooth portion that compresses comb formula frame 15 in inside position.
During thread-carrier 9 transverse motions, compress comb formula frame 15 and occupy its inside position; , compress comb formula frame 15 and be arranged in its outside position vertically then opposite during the laid processes of motion between the conveyer belt 3 at thread-carrier 9.Describe below under use compresses the situation of comb formula frame 15 and how to launch transverse motion.
Thread-carrier 9 traverses above the stay hook 4 of the vertical conveyer belt 3 that arrives in the end of laying track; In addition, hold down gag 11a, 11b are arranged in the position of its inoperative and compress comb formula frame 15 and be arranged in its outside position, referring to Fig. 5 and 10.Next hold down gag 11a, 11b drive in its operating position, at first also are retained in its outside position and compress comb formula frame 15; This state is shown in Fig. 4 and 6 and yet relate to Figure 10.From Fig. 4,6 and 7 obviously as seen, with the yarn of yarn beam 13 on the anchor portion of stay hook 4, be to remove from stay hook 4 with subregion 13a on the so-called needle-bar 30.
In order to implement traversing process in an orderly manner, to compress in next step that comb formula frame 15 is brought in its inside position and therefore and then hold down gag 11a, 11b will be turned back to again in its idle position, referring to Fig. 7 with to the transition portion of Fig. 8 for harmonious.This transition portion also in Figure 11 as seen.In the process that carries out the transition to its inside position, the tooth portion 16 that compresses comb formula frame 15 is engaging-in between the yarn of the outside near the yarn beam 13 of stay hook 4 extensions.In addition, this structure so realizes, the tooth portion 16 that compresses comb formula frame 15 acts on the yarn of yarn beam 13 from above, promptly acts on the hold down gag on this meaning equally.The result causes being positioned at according to the yarn of Fig. 8 yarn beam 13 below, zone of the needle-bar 30 on the stay hook 4; The subregion 13a that stretches out disappears.It is desirable to, the yarn beam 13 of newly laying also can abut in existed, be arranged on the yarn beam 13 on the stay hook 4 and be present in the more top zone of stay hook 4.
From Fig. 8 visible compressing comb formula frame 15 and the position of thread-carrier 9 with respect to vertical conveyer belt 3 implement transverse motion.Because this transverse motion is implemented by means of portal jib crane 6, thread-carrier 9 and compress 15 synchronous operations of comb formula frame, exactly, in the diagrammatic sketch of Fig. 8 perpendicular to drawing plane and outlying observation person.In contrast, vertically conveyer belt 3 moves towards the observer perpendicular to the drawing plane.Therefore the expansion of transverse motion is no longer described in Fig. 8.But its from top observation according to the diagrammatic sketch of Figure 11 to 13 obviously as seen.Mention, the single yarn 31 of the yarn beam 13 shown in amplifying to a great extent can be such as being the yarn of the leftmost side of the yarn beam of carrying in the accompanying drawings.The tooth portion 16 in four outsides of its compacted comb formula frame 15 covers and lays the width traction along stay hook 4 total, arrives the first idle stay hook 4 up to it.In addition, it remains on the back of the stay hook 4 that has existed all the time safely, because it is pressed downward tightly by the tooth portion 16 that compresses comb formula frame 15.
Lay the hook of the corresponding idle leftmost side of width if reached next, then thread-carrier 9 is in portal jib crane 6 next laid processes of enterprising Xingqi.Therefore it traverses above the row of stay hook 4 on the direction of opposed vertical conveyer belt 3 to the inherence.The yarn of yarn beam 13 skids off and slip between idle stay hook 4 from the tooth portion 16 that compresses comb formula frame 15 thus, and referring to Fig. 9, wherein, thread-carrier 9 is to left movement.Because during laid processes, portal jib crane 6 turns back in its original position again, compresses comb formula frame 15 and also turns back to together on the frame in its original position with portal jib crane, in addition, compresses comb formula frame and occupies its outside position again.Therefore, compress comb formula frame 15 has similarly illustrated the basic configuration of rectangle in any deployment cycle with respect to frame the tracks of sealing.This rectangle also can have the angle of rounding, is varied to occluded ellipse, ellipsoid or according to how realizing practically that the control (wherein decide on higher speed) that compresses comb formula frame 15 realizes being out of shape.When thread-carrier 9 and portal jib crane 6 arrives opposed vertical conveyer belt 3, there is foregoing same precondition.This process can be carried out repetition in same mode.
What must remind is only to have described an embodiment by means of accompanying drawing.Compressing comb formula frame 15 also can also be parallel to the direction motion of vertical conveyer belt 3 and place its fixture by this way.Therefore, its second component motion that is parallel to tracks extension of thread-carrier 9 needn't under any circumstance all be applied by portal jib crane 6.This promptly compresses comb formula frame 15 and is installed on frame or the thread-carrier 9 such as being this situation.
Compressing comb formula frame 15 in the accompanying drawing in front illustrates with pin that is designed to the straight line stretching, extension and the tooth portion 16 that moves on the direction of first component motion that compresses comb formula frame 15 all the time.But according to single situation can advantageously be another kind of profile of tooth also.Figure 14 has showed a kind of like this profile of tooth of change, particularly referring to the subregion of irising out.According to diagrammatic sketch, tooth portion has the shape of plain hook 32.Plain hook is positioned on the plane of motion that compresses comb formula frame 15.In addition, dog hole 32a be designed to yarn beam 13 yarn grab the hole.Be directed near the row of stay hook 4 with its first component motion if compress comb formula frame 15, then motion is grasped in the hook 32 extra side of also carrying out with its dog hole 32a on the yarn of yarn beam 13.Here, when shifting to stay hook 4, tilt and move downward,, then strengthened and grasped and keep effect as illustrating by means of Fig. 4 (referring to Reference numeral 33) at its plane of movement if compress comb formula frame 15.
