Loom of the present invention is pressed circular configuration design (referring to Fig. 1,2), mainly comprise annular reed 3 and support 13, the shuttle 5 of operation in annular reed 3 and the core 4 at annular reed center that upper and lower reed plate 22,23 and dent therebetween 12 are formed, be distributed on around the annular reed 3 many groups shedding motion 1 and through yarn feeding device 2, it is characterized in that also comprising the core elevating mechanism 14 that is positioned at annular reed 3 centers, and with communication line 29 and described shuttle 3, shedding motion 1, through yarn feeding device 2 master control set 9 that line program controls of going forward side by side that links to each other with core elevating mechanism 14; Described shuttle 5 is electric shuttle 5 (referring to Fig. 1,2,3,4,5), the decelerator 26 and the power wheel 17 that comprise small machine 16 in the roller 24 that is installed in shuttle body 30 bottoms and the shuttle body 30, link to each other successively with small machine 16, and pirn 18 and spring support 20 thereof; The dent 12 of described annular reed 3 is paid for the engaged transmission of mating mutually with described power wheel 17; Also comprise and be installed in the shuttle body 30 inboard conducting strips 15 that are electrically connected with small machine 16; Be equipped with on the upper and lower reed plate 22,23 of described annular reed 3 and described conducting strip 15 electrode in contact 11; Reductor 26, uni-drive gear box 27 and lifting screw 28 that described core elevating mechanism 14 (referring to Fig. 2,6) comprises motor 25, joins successively with motor 25; Described core 4 can be installed in the upper end of described lifting screw 28, and the position is corresponding with the height of annular reed 3, so that the height basically identical of fell and annular reed 3.
One of key technology of loom of the present invention is described electric shuttle 5 (hereinafter to be referred as shuttle 5 or an electronic shuttle 5).It comprises three major parts (referring to Fig. 3,4,5): the one, and shuttle body 30 is designed to streamlined; The 2nd, shuttle operation part, the decelerator 31 and the power wheel 17 that mainly comprise small machine 16 in the roller 24 that is packed in shuttle body 30 bottoms and the shuttle body 30, link to each other successively with small machine 16; The dent 12 of described annular reed 3 is paid for the engaged transmission of mating mutually with described power wheel 17; Also comprise and be installed in the shuttle body 30 inboard conducting strips 15 that are electrically connected with small machine 16; On the upper and lower reed plate 22,23 of described annular reed 3, be equipped with and described conducting strip 15 electrode in contact 11.When master control set 9 transmits work order by communication line 29, described electrode 11 is connected electricity, bring power, and the described small machine that is attached thereto 16 is rotated, and then make decelerator 26 and power wheel 17 rotations that link to each other successively with small machine 16 by contacted conducting strip 15 with it.Because described power wheel 17 is meshed with the dent 12 of described annular reed 3, and described annular reed 3 be fixed on its support 13 motionless, so, described shuttle 5 just can mesh in the rotation processes at the dent 12 of described power wheel 17 with annular reed 3, travel forward voluntarily, also being described power wheel 17 rolls across a tooth on fixing cylindrical dent 12, just walk the forward distance of a tooth of shuttle 5.Because rotating with dent 12 engagements of annular reed 3, action of centrifugal force, described power wheel 17 can keep the works fine state all the time.Though the walking of shuttle 5 relies on power wheel 17 and the active force that dent 12 engagements provide, the passive rolling that also needs to be packed in the roller 24 of shuttle body 30 bottoms cooperates, and it can support whole shuttle 5 and move soon in that the upper surface of reed plate 23 down is sliding.Again because annular reed 3 (comprising upper and lower reed plate 22,23 and described electrode 11) provides a circuit orbit or race, so shuttle 5 can be made circular motion around the core 4 of annular reed 3 centers.Third part is that weft yarn is supplied with or the wefting insertion part.This part mainly comprises pirn 18 and spring support 20 thereof.Spring support 20 is packed on the shuttle body 30, and pirn 18 is being supported in clamping.Weft yarn 7 can be drawn from warp-wise on the pirn 18, and the spring 32 on the support has certain force of strain when weft yarn 7 is drawn, so that along with the operation of shuttle 5 and the warp thread 6 of opening interweave smoothly in described core 4 vicinity (referring to Fig. 1,2).Compare with existing loom, loom of the present invention does not have the essential complicated picking mechanism of ordinary loom when weaving multiple layer fabric (particularly).The motion of the conventional shuttle of existing circular loom is all adopted and is positioned at the mechanical arm that annular reed 3 center transmission mechanisms stretch out and promotes or drive, thereby it also must have a cover complicated mechanical transmission device and a control device, the shuttle 5 of loom of the present invention adopts electricity directly to drive the small machine 16 that is built in shuttle body 30 source that is used as power, abandon original circular loom shuttle and drive necessary complicated mechanical transmission device and control device, thereby can make that loom structure of the present invention is simple, cost descends, maintenance also meets the designing requirement of modern comfort brevity and lucidity easily.The electronic shuttle 5 of loom of the present invention is not owing to need complicated external picking mechanism or the pushing mechanism just can trouble-free operation in annular reed 3, thereby can be called shuttle 5 or automatic shuttle 5 voluntarily yet.
The dent 12 of the described annular reed 3 of loom of the present invention is paid for the engaged transmission of mating mutually with described power wheel 17; Comprise two layers of meaning: mean that on the one hand described dent 12 is not the same with conventional dent shape and structure, i.e. the present invention requires dent 12 that the matching relationship that is meshed with described power wheel 17 will be arranged.In other words, dent 12 and layout thereof will have modulus and the pitch that matches with described power wheel 17.And the profile of tooth of dent 12 both can be the tooth-formation of gear structure; Being gear pair engagement (corresponding power wheel 17 also can be called gear 17), also can be the cylindrical structural of sprocket wheel, and promptly sprocket wheel is paid engagement (corresponding power wheel 17 also can be called sprocket wheel 17).For simply, the fit form that the embodiment of the invention has adopted sprocket wheel to pay.But the engagement of described power wheel 17 and described dent 12 can be adopted the mesh form of gear pair fully.Mean that on the other hand described dent 12 is more than the effect of conventional dent, promptly it not only comprise conventional dent the reed effect that should play, also played the effect of the not available shuttle engaged transmission of conventional dent simultaneously.In other words, two all over the body of the annular reeds 3 of loom of the present invention are to knit reed, are again that the transmission of shuttle 5 operations is paid.Design directly is meshed with dent 12 (gear or chain strip) though the embodiment of the invention has provided this power wheel 17, but do not get rid of other engagement design form, for example, do not change the planform of annular reed 3 and dent 12, but a circle tooth bar is installed in addition on the correct position between the upper and lower reed plate 22,23, make it to be meshed, can realize purpose of the present invention equally with described power wheel 17.
The described annular reed 3 of loom of the present invention (referring to Fig. 3,4,5) mainly comprises upper and lower reed plate 22,23, is fixed on the dent 12 and the inboard betwixt electrode of installing respectively up and down 11 in the outside therebetween.Described dent 12 should match with the width and power wheel 17 installation sites of described shuttle body 30 with the distance between the outside in electrode 11 is in upper and lower reed plate 22,23, contact so that described electrode 11 is gone up the conducting strips of installing 15 with shuttle body 30 inboards, and can provide electrical source of power to the small machine 16 that is electrically connected with conducting strip 15 by described conducting strip 15; Described power wheel 17 is suitably meshed, to drive shuttle 5 even running in annular reed 3 with dent 12.For described conducting strip 15 better or is more stably contacted with electrode 11, further feature of the present invention is to have designed the spring 33 that is built in 30 li of shuttle bodies, and described conducting strip 15 and shuttle body 30 built-in springs 33 are connected.Be subjected to the effect of shuttle body 30 built-in springs 33, can keep conducting strip 15 to contact with the all-the-time stable of electrode 11.
Small machine 16 of the present invention both can be an alternating current generator, also can be direct current generator.The embodiment of the invention has adopted direct-flow small motor 16.Corresponding direct-flow small motor 16, electrode 11 and conducting strip also can be described as positive and negative electrode 11 (11 ') and positive and negative conducting strip 15 (15 ').For safety, exchange small machine 16 no matter be to use, also be to use direct-flow small motor 16, voltage should be controlled in the safe voltage scope.Simultaneously, upper and lower reed plate 22,23 also should be the insulating materials manufacturing.In addition, for direct current generator 16, both can use the power supply power supply of AC-DC, also can adopt the storage battery power supply.When adopting the storage battery power supply, storage battery also can be placed in the described shuttle body 30, directly is direct current generator 16 power supplies.
For shuttle 5 supporting design, 2 points to be described also with annular reed 3: for make shuttle 5 in annular reed 3, operate steadily, smooth and easy and sliding soon, one will design the body width and the shape of shuttle body 30; The 2nd, think about the installation site of described power wheel 17 in shuttle body 30.The former can guarantee that the conducting strip 15 on the described shuttle body 30 smoothly contacts all the time with electrode 11 on the annular reed 3, and the latter then can guarantee dent 12 correct engagement on power wheel 17 and the annular reed 3 in the shuttle body 30.The shuttle 5 shuttle bodies 30 of the embodiment of the invention design camber line shape that the curvature that is shaped as respectively the electrode 11 installed with described annular reed 3 inner and outer rings and dent 12 of both sides is complementary inside and outside width, the corresponding coupling of width consistent or smaller (referring to Fig. 4,5) of the intermediate host partial width of shuttle body 30 and the span width or the race of annular reed 3 inner and outer rings in other words.Though it is sliding type that embodiment provides the way of contact of described conducting strip 15 and electrode 11, but can be designed as other ways of contact fully, the way of contact of for example rolling, but this moment should correspondingly improve or redesign the intermediate host partial width or the shape of shuttle body 30.
Another key technology of loom design of the present invention is the core elevating mechanism 14 (being called for short elevating mechanism 14) that is installed on annular reed 3 centers.Reductor 31, uni-drive gear box 27 and lifting screw 28 that described elevating mechanism 14 (referring to Fig. 2,6) comprises motor 25, joins successively with motor 25.Described motor 25 is common alternating current generator.Supporting with it reductor 31 can be reduced to the speed of motor 25 enough low, again the reduction of speed by uni-drive gear box 27 be transformed into vertical transmission by horizontal transmission, thereby drive moving up and down of lifting screw 28.This transmission mechanism that overlaps lifting screw 28 is also uncomplicated, is that this area scientific and technical personnel institute is understood and realization easily.But note design principle of the present invention, promptly reasonable in design the adjustable height that is installed in described annular reed 3 center lifting screws 28 or speed and the described shuttle 5 that moves in a circle around annular reed 3 center lifting screws 28 (driving weft yarn 7) movement velocity matching relationship, make the position of the core 4 that is installed in lifting screw 28 upper ends corresponding with the height of annular reed 3, keep the formed cloth fell basic horizontal of core 4 peripheries, in other words with the height and position basically identical of annular reed 3, so that warp thread 6 is smooth with weft yarn 7, be woven into the fabric 8 that is attached to core 4 surfaces reposefully.Though the embodiment of the invention has only provided a kind of comparatively simple mechanical type core and has touched elevating mechanism 14, but and get rid of and adopt other forms of mechanical lifting gear 14, do not get rid of (on-mechanical formula) elevating mechanism 14 that adopts other kinds yet, as, hydraulic pressure lifting mechanism, Pneumatic type hoist structure etc., as long as satisfy described design principle of the present invention, all to get final product in other words by design principle design of the present invention.
Described core 4 is the hollow fabric form supporters by shape of product requirement design.Which type of core 4 is arranged, just can weave out which type of hollow fabric 8.In theory, the shape of core 4 can be arbitrarily, thereby the shape of hollow fabric 8 also is arbitrarily.But after will considering that in fact fabric 8 weaves, the problem that withdraws from of core 4.According to actual needs, the shape and structure that utilizes the hollow fabric 8 of several typical cases that loom of the present invention woven as shown in figure 12.The material of core 4 is generally timber or plastics.It will have the planform that cooperates with lifting screw 28 upper ends, so that can stably be installed on the lifting screw 28, can successfully take down from lifting screw 28 after weaving end again.The concrete structure that embodiment has adopted jackscrew suit or snap ring to install.
Another innovative point of loom of the present invention is the combined type design of loom integral body, be its any one principal organ or device, as, through yarn feeding device 2, shedding motion 1, annular reed 3 and shuttle 5, core 4 and elevating mechanism 14 thereof, and described each device carried out programme controlled master control set 9 etc., can independently exist, between them without any mechanically contact, therefore, install, adjust, maintenance, change each or certain part wherein, all do not have what influence or essence influence each other.Particularly this combined type designs, and has greatly strengthened the applicability of loom of the present invention, has also created low-cost condition for the raising of loom of the present invention, improvement.For example, the shedding motion 1 of the embodiment of the invention and adopted 6 groups of designs (referring to Fig. 1) through yarn feeding device 2 when it being reduced to 4 groups, perhaps is increased to 8 groups, even more, can not have influence on core 4 and elevating mechanism 14 thereof.Can not have influence on annular reed 3 and support 13 thereof and the shuttle 5 of operation in annular reed 3 yet.What of design textile 8 required warp thread 6 radicals shedding motion 1 and through what of 2 groups of numbers of yarn feeding device depend primarily on.If every group of shedding motion 1 and warp thread 6 radicals that can settle through 2 of yarn feeding devices are certain, when Dobby Weave Design need significantly increase warp thread 6 radicals, loom of the present invention just can be simply by increasing shedding motion 1 and solving through the quantity of yarn feeding device 2.According to calculating, generally use 4-16 group shedding motion 1 and just can satisfy actual needs through yarn feeding device 2.Again for example,, just can only increase the diameter dimension of annular reed 3, can not change core 4 and elevating mechanism 14 thereof if want to increase the diameter dimension of annular reed 3.Also can increase or not increase shedding motion 1 uniform around the annular reed 3 accordingly and, also can not have influence on the electric shuttle 5 that annular reed 3 in, moves simultaneously through the group number of yarn feeding device 2.Suppose that according to the designing requirement of organizing that stage is produced fabric, the diameter of the annular reed 3 of embodiment design is too little, the annular reed 3 that needs super-large diameter just can be finished the work, and so, the annular reed 3 that only needs to make a required diameter size gets final product.Utilize this fabricated structure of loom of the present invention, can be existing through yarn feeding device 2, shedding motion 1, shuttle 5, core 5 and elevating mechanism 14 thereof, and described each device carried out passing such as programme controlled master control set 9 (except that elevating mechanism 14, each device has all designed castor, only need pass) near the new annular reed 3, just can be assembled into a new playscript with stage directions invention loom with it.Its cost low, the height of its efficient, its specificity is strong, does not say and bright.After interim task was finished, loom can also restore at an easy rate.Again for example, change structure, the shape of electric shuttle 5 separately, except that needing that the corresponding mating part that uses annular reed 3 as race is done the corresponding change, the mechanism of other parts or device can not make any changes.This has brought very big facility for promoting the use of of new technology.Therefore, loom of the present invention has simple in structure, processing ease, the outstanding feature that wide adaptability and practicality are good.
The basic configuration of the annular reed 3 that loom Combination Design of the present invention is used and the annular reed of existing circular loom are basic identical, but its concrete structure, have all done obvious improvement with the fit system of shuttle and the shape and structure of dent 12; Annular reed 3 with its around uniform shedding motion 1 and also used for reference the version of existing circular loom through yarn feeding device 2, but shedding motion 1 and through the group number of yarn feeding device 2 also far more than existing circular loom, and each shedding motion 1 and through 2 heald frames that can carry of yarn feeding device, heald and warp thread quantity also much larger than common circular loom, but with regard to non-circular ordinary loom, the little model machine of computer particularly, described shedding motion 1 and through yarn feeding device 2 and to utilize their master control set of programme-control 9 all be prior art (referring to Chinese patent ZL95200613.8 number) in essence.For with loom Combination Design of the present invention, only to existing shedding motion 1 with through yarn feeding device 2 and utilize their master control set of programme-control 9 to make matching or adaptations.This understands easily and can realize without creative work for those of ordinary skills.
Loom of the present invention designs for fabricated structure.Described shedding motion 1, shuttle 5 and elevating mechanism 14 are independent separately, each other without any mechanical connection, are to utilize communication line 29 and described master control set 9 to couple together, and by master control set 9 they are carried out the programme-control of work and coordination.Fig. 7 has represented system's control block diagram of 9 pairs of shedding motions 1 of the described master control set of loom of the present invention, shuttle 5 and elevating mechanism 14; Fig. 8 has represented the master control system FB(flow block) in the described master control set 9 of loom of the present invention; Fig. 9 has represented in the described master control set 9 of loom of the present invention FB(flow block) to shedding motion 1 control; Figure 10 has represented in the described master control set 9 of loom of the present invention FB(flow block) to electric shuttle 5 controls; Figure 11 has then represented in the described master control set 9 of loom of the present invention FB(flow block) to 14 controls of core elevating mechanism.In described each program, 9 pairs of shedding motions 1 of master control set, the program of controlling through yarn feeding device 2 are prior aries, need not give unnecessary details; For electric shuttle 5 control programs and elevating mechanism 14 control programs, though newly establish, all very simple.Because only needing to control it, the former whether moves and the speed speed, the latter also only need to control its lifting whether with the speed speed, as for cooperatively interacting between the rising or falling speed of the speed of service of shuttle 5 and core elevating mechanism 14, with the high and low position of maintenance fell and the height basically identical of annular reed 3, it is a simple linear relationship programming, also uncomplicated, the those of ordinary skill in this field can be realized easily without creative work.
The operation principle of loom of the present invention following (referring to Fig. 1,2): warp thread 6 is drawn through yarn feeding device 2 from each group, by the corresponding heald 10 that passes on each group shedding motion 1 of Dobby Weave Design requirement, enter respectively between the dent 12 of annular reed 3, draw back bondage or mounting board again on top according to the core 4 of fabric form requirement design (Fig. 2 embodiment provide connect frustum of a cone shape for cylinder).At this moment, the top height and position of core 4 basic with annular reed 3 upper and lower reed plates 22,23 between the center consistent, the top height and position of core 4 will make in the shuttle body 30 pirns 18 be drawn out to one section weft yarn, the 7 basic maintenance levels of (workspace) between near core 4 fells in other words.Weft yarn 7 can be with any one or one group of warp thread 6 bondage or the mounting board top at described core 4.Require to set the fabric structure parameter according to product design on the keyboard in master control set 9, as through close, filling density, organization chart and opening pegging plan etc., and provide other weaving process parameters, as shuttle speed, core raising speed etc.After preparation finishes, check errorlessly, can drive.Under the enabled instruction of master control set 9, shuttle 5 is that driving force can be slided fast operation with the electricity between the upper and lower reed plate 22,23 of annular reed 3.Under described control of correspondent program, the warp thread 6 on one group of shedding motion 1 in shuttle 5 operation the place aheads should keep open state; Warp thread 6 openings form in canopy, shuttle 5 can pass through smoothly; Owing in shuttle 5 operation, can draw continuously, equably from the pirn in the shuttle body 30 18 and discharge weft yarn 7 in other words, thereby, when shuttle 5 described when in canopy, passing through, near the fell place core 4 has promptly finished interweaving through, weft yarn 6,7.When shuttle 5 passes through one group behind yarn feeding device 2 and shedding motion 1, master control set 9 just can detect corresponding signal, after shuttle 5 has just been passed through one group requires the warp let-off in time and conversion open state through yarn feeding device 2 and shedding motion 1 according to Dobby Weave Design, keeps and is waiting for passing through in other words of shuttle 5 next time and interweaving of shuttle 5 next circle.After shuttle 5 is casted off one or more layers, core 4 is under the lifting of its elevating mechanism 14, the height of back one deck weft yarn 7 of interweaving that in time moves upward to keep the basic horizontal at fell center and shed open center, keeps the basic horizontal of one section weft yarn 7 in the workspace in other words.Shuttle 5 is round and round along through canopy race operation, wefting insertion or provide weft yarn 7 and warp thread 6 to interweave constantly or continuously simultaneously, core 4 also corresponding in time by lifting, thereby can weave described fabric 8 in the gabarit of core 4.Because warp thread 6 is to send to its center (core 4) warp-wise around uniform annular reed 3, though and weft yarn 7 also is to draw along the warp-wise of annular reed 3, but it and interweaving of warp thread 6 are owing to the circumferential movement of shuttle 5 along annular reed 3 realizes interweaving, therefore, interweaving of this warp, weft yarn 6,7 is not that the formed plane of ordinary loom interweaves, but solid interweaves or three-dimensional interweaves (non-stricti jurise); In fact more precisely, do not interweave between warp, the weft yarn 6,7, but around knitting---weft yarn 7 is knitted at plane pile warp yarn 6.Just be attached to the gabarit of the core 4 of its shape of decision through, the fabric 8 of weft yarn 6,7 after knitting, and with core 4 little by little by 14 liftings of core elevating mechanism and along the axial rising of annular reed 3, the fabric 8 that promptly weaves is separated from the XY working face when weaving and rises along the Z axle, thereby is made into the hollow fabric of described three-dimension curved surface.As for multiply cloth, be prior art, can directly implement to utilize for loom of the present invention.Several fabric tissues commonly used are set in aforesaid corresponding program, call during use to get final product.If new organization design, revise or set by keyboard in the master control set 9 and screen and also be easy to.Therefore, hollow fabric and two or more the hollow solids that use loom of the present invention can weave out various multi-layer three-dimension curve forms do not have special-shaped hollow the knitting that seam is combined into one.Figure 12 has only provided the shape and structure schematic diagram of several typical multi-layer three-dimension curved surface hollow fabric embodiment that loom of the present invention weaves out.Wherein, a represents the hollow fabric of multi-layer three-dimension cylinder; B represents the hollow fabric of multi-layer three-dimension cylinder; C represents the hollow fabric of multi-layer three-dimension circular cone stage body; D represents multi-layer three-dimension cylinder and the hollow fabric of the jointless abnormity of circular cone stage body; E then represents the hollow fabric of the streamlined curved body of multi-layer three-dimension.Be not difficult to find out that from Figure 12 d its body is the assembly of Figure 12 a and c body.This means, the as a whole hollow fabric of three-dimension curved surface abnormity of the no seam combination of every two or more bodies between each body shown in Figure 12, loom of the present invention all can be weaved.According to described weaving principle, at the as a whole hollow fabric of three-dimension curved surface abnormity of the no seam combination of its allothimorph shown in Figure 12 or body, loom of the present invention can not weaved equally.Figure 13 has also only provided the institutional framework schematic diagram of several typical multi-layer three-dimension hollow fabric embodiment that loom of the present invention weaves out.Wherein, a represents eight Five Wei fabric institutional framework schematic diagrames;
