Detailed description of the present invention
An embodiment who is used for making the full duration carpet who selects the purpose that is used to represent has been shown in Figure 1A, and this embodiment comprises that a wool knitting yarn forms assembly 38 and a drum assembly 49, and they are by yarn creel 62,64 and 66 and cotton rope frame 68 and 70 feed.The formation of carpet backing and installation system is to lean on: the oncus on the mandrel that forms assembly 38 at wool knitting yarn is to the multiply cotton rope, such as cotton rope 30,32,34 and 36, lead, and round this mandrel and on cotton rope winding yarn, such as yarn 40, yarn is welded on the cotton rope, and yarn is cut off, so that produce a plurality of elongated fine hair article, or wool knitting yarn.Many wool knitting yarns, such as wool knitting yarn 42,44,46 and 48 are provided with abreast, and they are welded in the base fabric substrate 50 that is supported on the drum assembly 49.In this system, on single mandrel, form four wool knitting yarns simultaneously, as explaining below.Best, the surface of a cylinder 52 in transversal the drum assembly 49 nine positions of separating, such as being position 54,56,58 and 60, is provided with eight wool knitting yarns (only showing four) abreast in groups.Form in the process of carpet a end that the clip (not shown) is clamped base fabric simultaneously in the cylinder the inside in the cylinder rotation.
When guiding on cylinder during every group of eight wool knitting yarn, make the cylinder rotation, and move in the horizontal, like this, wool knitting yarn is moved on the base fabric, and move to a plurality of ultrasonic horn (not shown)s below, these ultrasonic horns the wool knitting yarn fusion weld to base fabric.When base fabric continues along the direction rotation of arrow 51 and horizontal when mobile along the direction of arrow 53, every group of eight wool knitting yarn form a wool knitting yarn of arranging spiral on cylinder 52.After one of cylinder changes, wool knitting yarn just soldered in one group is in connection with the first soldered wool knitting yarn, and separate with them and to equal in eight one group by the distance of a wool knitting yarn to the interval of the adjacent wool knitting yarn of next root, this is generally 0.2 inch for common wool knitting yarn density.After 10 of cylinder changes, first group of eight wool knitting yarn will with first of the second group of eight wool knitting yarn soldered end alignment, the adjacency of wool knitting yarn appears at the stitch connecting portion.There is this situation by one group of wool knitting yarn in whole transversal cylinder to next group wool knitting yarn, so, a carpet backing and installation system of having finished has appearred on cylinder now.At this moment stop the rotation of cylinder, stop the formation of wool knitting yarn, and the stitch connecting portion is aimed at a shearing device.Plate is in the slip underneath of wool knitting yarn and their welders separately, and they are improved, and leaves cylinder.This shearing device crosses along the stitch connecting portion of aiming at, and all wool knitting yarns and base fabric are cut off, and carpet is unclamped by cylinder, provides 15 feet long carpets, and this is equivalent to the girth of cylinder.Can install to another piece base fabric on the cylinder now, can navigate to the starting point place to this cylinder in the horizontal once more, can restart the formation of wool knitting yarn and wool knitting yarn is welded on the base fabric.Can be the edge trimming of the carpet that processes, to obtain one 12 feet * 15 feet square carpet, begin to make next piece carpet simultaneously.Figure 1B schematically shows one group of wool knitting yarn 59 spiralitys ground the how wool knitting yarn 61 adjacent with another group being separated and twines.Group 59 has a starting point 63, and group 61 has a starting point 65.Carry out spiral winding to organizing 59, like this, the wool knitting yarn that has just welded, for example in the position 67 wool knitting yarn in connection with the wool knitting yarn that has welded, 69 wool knitting yarn for example in the position.Little by little, the wool knitting yarn group 59 that has just welded is also in connection with the wool knitting yarn that has welded of adjacent group 61, such as in the position 71 and position 73.At last, 55 wool knitting yarn group 59 ends that just welded run into for the starting point 65 of organizing 61 ground, end in the position, as shown in the figure, form a stitch connecting portion.Subsequently, process stops, and the carpet backing and installation system of finishing is cut off, and leaves cylinder.
Can only adopt 72 wool knitting yarns to make a whole carpet, these wool knitting yarns can only adopt the yarn of 18,36 or 54 ends.In presents, adopt the yarn of 36 ends, like this, once on four wool knitting yarn mandrels, twine two one threads, can form wool knitting yarn quickly than a yarn that only twines with relatively more rational speed of wrap with a velamen.In addition, if adopt a plurality of ends, the favourable mixed and disorderly blending of yarn end can appear along the length of a wool knitting yarn; Like this, along a wool knitting yarn and can be being mixed by the end of an one thread the slightly different of color to the end of another one thread to another root wool knitting yarn by a wool knitting yarn, this can reduce owing to the different vitta defectives that cause of color.For increase or the more variable ability of style that more speed is arranged, can on a mandrel, twine three or more ends as needing; For example, three ends can be different colours or dissimilar yarns.
In Figure 1A, show and be used for large-duty three yarn creel assemblies 62,64 and 66.Assembly put be used for the moving yarn end 36 volume yarns and be used to back up 36 volume yarns of end, can adopt transfer tails that these backup reel for yarns are connected on the moving yarn volume in a conventional manner, thereby continuous yarn supply can be arranged.Another yarn creel assembly that illustrates is in order to be provided for the yarn that product changes.The 3rd yarn creel assembly can be used for further product and change, or is used for the operation of more end, so that operation or style change quickly as mentioned.
Show two cotton rope frame components 68 and 70, adorn 80 cotton rope volumes altogether.Because can on big volume, provide cotton rope, its depletion rate than yarn slowly many, so can not need to be used to connect the additional volume of transfer tails.When single cotton rope is not wound, wish these cotton ropes not to be carried out twist yarn, so, preferably rollably take out for each volume.Periodically, when stopping, can replenishing single cotton rope volume simultaneously as required for the good carpet of welding being shifted out by cylinder.Can adopt more cotton rope frame component, thereby make the replacing of volume become easier.Usually, for the change of yarn product, do not change cotton rope.
Fig. 2 show 2-2 that wool knitting yarn forms assembly 38 to end-view, and a basic single mandrel wool knitting yarn that shows the mandrel 74 that adopts four wool knitting yarns forms the details of device 72.The critical piece that wool knitting yarn forms device 72 is 76, two ultra-sonic welded assemblies 78 of 75, one Yarn winding devices of 74, one frameworks of mandrel and 84, one shearing devices 86 of 80, one yarn supply assemblies and a wool knitting yarn driven unit 88 of four sides.By an idle running feed roller 90 and the feed roller 92 that is driven yarn 40 is sent to, the hydraulic cylinder 94 that works round pivot 96 presses together these two rollers, yarn 40 is clamped, can be comprised one or more yarns end for each mandrel.Cotton rope 30,32,34 and 36 send to by an idle running feed roller 98 and the feed roller 100 that driven, and the hydraulic cylinder 102 that works round pivot 104 presses together these two rollers.Four cotton ropes are sent to the entrance point 106 of mandrel 74, guide every cotton rope by a pipe that separates in the center hollow part in mandrel there, keep these cotton ropes to be separated from each other, and prevent to tangle.Carriage 107 on the side in the downstream of shearing device 86 of mandrel is attached to this mandrel on the framework 75, and this structure makes the yarn that is wound be thrown off by mandrel, and forms four cut wool knitting yarns of the fine hair that separates.By an idle running outlet roller 109 and the outlet roller 111 that driven wool knitting yarn 42 ', 44 ', 46 ' with 48 ' send to, the hydraulic cylinder 119 that works round pivot 121 presses together these two rollers, and these wool knitting yarns are clamped.The roller 111 that is driven is fluted, and with the wool knitting yarn of civilian dress " U " font, idle roller 109 has the rib that fits into groove, makes wool knitting yarn therein.
Fig. 4 shows the port of export 108 that entrance point 106 that the yarn of this mandrel enters and yarn are gone out.Fig. 5 is the sectional view of an amplification of the port of export, the figure shows a Returning wheel for every one thread, and this is taken turns by passage 110 these yarns of guiding in the hollow at the center of mandrel 74.Wheel 112 guiding yarns 30, wheel 114 guiding yarns 32, wheel 116 guiding yarns 34, wheel 117 guiding yarns 36.These yarns will be directed in the groove on the mandrel bight, as below will discussing by passage 110.
Wind 76 twines yarn round mandrel, and twines on the supporting cotton rope in the groove on the bight of mandrel, and this wind comprises the peg or spindle 118 of a hollow, and it has a yarn entrance point 120 and a yarn outlet end 122.A bearing assembly 124 that is attached on the framework 75 rotatably maintains this peg or spindle.A motor 126 that works by a belt pulley and belt dressing 128 makes this peg or spindle rotation.When yarn 40 when mandrel 74 twines, cotton rope 30,32,34 and 36 march forward (downwards) in the axial direction along mandrel, are carrying cotton rope and yarn leaves wind, and arrival ultra-sonic welded assembly 78 and 80.
Fig. 3 shows the isometrical drawing of weld assembly 78, and this assembly is identical with assembly 80, and carriage all installs to two assemblies on the framework 75 in the mode of aiming on the relative side of mandrel 74 with 132 such as carriage 130.Basic weld assembly comprises the ultrasonic horn 134 and the ultrasonic drivers 136 that is attached on the framework 138 that are attached on the amplifier 135.Framework 138 is installed on the four lever linkage assemblies 140 and (shows two bars), and this linked component is attached on the carriage 132.At the U-shaped carriage 144 on the rod end 146 hydraulic cylinder 142 is attached on the framework 138, and hydraulic cylinder 142 is attached on the carriage 130 on the cylinder ends.The motion of hydraulic cylinder boom end 146 makes ultrasonic drivers, and amplifier and soldering tip assembly leave mandrel with forward direction motion, keep vertical with mandrel 74 simultaneously, thereby is squeezed in the yarn between the cotton rope on soldering tip and the mandrel; Mandrel in this state is as a ultrasonic anvil block.Yarn and cotton rope are pressed together, simultaneously ultrasonic energy is applied on the soldering tip, make that yarn and cotton rope are heated rapidly, thereby yarn fibers is melted each other, and cotton rope is melted at the position of their contacts.Yarn can not adhere on the soldering tip, and cotton rope can not adhere on the mandrel yet.The pressure of hydraulic cylinder has been determined in the squeezing action power that applied between mandrel and the soldering tip and between yarn in the middle of their and the cotton rope.This active force is a key factor determining to be coupled to the quantity of the ultrasonic energy on yarn and the cotton rope.Other factor is the amplitude and the frequency of the vibration of soldering tip.
Fig. 6 A-C shows the shape of soldering tip, and this soldering tip allows that a soldering tip once is welded to two cotton ropes on the yarn.Like this, there are four cotton ropes of the mandrel guiding of four sides only to need two soldering tips in order to weld along one.Soldering tip 134 has the surface 148 and 150 of two band angles, and yarn and cotton ropes (the two does not all illustrate) are pushed facing to the bight 152 and 154 of mandrel 74 respectively in this two-surface.These surfaces are sufficiently long, thereby if use a bigger mandrel 74a, identical soldering tip 134 still can be joined together yarn and cotton rope facing to the bight of mandrel 74a.For the mandrel of pros that go out as shown, surface 148 with 150 with 156 one-tenth miter angles in side of mandrel, shown in label 158.For the hexagonal mandrel that a soldering tip welds on two adjacent bights, this angle will be 30 degree.The shape of surface 154 (with surface 156) has been shown with the profile that amplifies in Fig. 6 B, and it has the leading-in end of a band angle, and this end has a radius of curvature 160, is used for guiding the yarn below soldering tip.Yarn can advance with the direction of arrow 162.In Fig. 6 C, the degree of depth 164 of soldering tip 134 is very little, make that the soldering tip stress that length produced by surface 148 and 150 is minimum, and this degree of depth is sufficiently big, so that remove all yarns that expection is used with the mandrel of wanting usefulness.The width 166 of soldering tip 134 is approximately 0.5 inch, this width and ultrasonic amplitude, and frequency, and the power of driver is relevant.
Referring to Fig. 5, each soldering tip such as soldering tip 134, is used to two supporting cotton ropes such as cotton rope 30 and 36, are welded on the winding yarn 40 thereon.Preferably this work is finished on the surface 148 and 150 of the band angle by soldering tip 134 is set, and like this, these surfaces are substantially perpendicular to by cotton rope and divide equally by the determined imaginary plane that comprises the angle of yarn in the both sides of every cotton rope.Like this, when yarn cut off is formed the cut wool knitting yarn of fine hair, form identical angle in the substrate of wool knitting yarn at wool knitting yarn of the both sides of cotton rope, these wool knitting yarns are welded in this substrate.Imaginary plane 153 is by cotton rope 30, and divides equally comprise angle 155 between the end 157 and 159 of yarn 40 crooked on the cotton rope 30.The surface 150 is substantially perpendicular to plane 153, as represented with label 161.Similarly, imaginary plane 163 is by cotton rope 36, and divides equally comprise angle 165 between the end 167 and 169 of yarn 40 crooked on the cotton rope 36.The surface 148 is substantially perpendicular to plane 163, as represented with label 171.Notice that imaginary plane 153 and 163 also intersects in the center or the shape center in the cross section of mandrel 74.
Referring to Figure 4 and 5, twining on four sliders 168,170,172 and 174 of yarn 40 on the side of mandrel 74.These sliders are maintained in the shallow slit in the side of mandrel.The purposes of these sliders is the girths that are increased in the mandrel that yarn looks by yarn before soldered.These sliders contiguous soldering tip 134 and 134 ' 176 places, position stop.If yarn is nylon 6-6, have been found that yarn shrinks significantly owing to the cooling after the ultrasonic heating, so when yarn movement left soldering tip, it crossed the slider at 176 places, and may be collapsed to a less girth, and can not bond on the mandrel.
After welding, must cut off yarn 40, so that it is thrown off by mandrel 74.When the middle cut-out between cotton rope strictly, the last lint height of yarn when wool knitting yarn being fitted in the carpet can be determined in cut end.When strictly cutting off and assembling, in last carpet product, do not need further lint to shear, still,, shear and may remain preferred for some product.Shearing device 86 in Fig. 2 is made of the circular shear blade of four rotations, and each blade is pressing a bed plate that is fixed on the mandrel.Figure 4 illustrates such bed plate 178 in the slit 180 that is installed in mandrel 74.Fig. 7 A show by the 7-7 of Fig. 2 to profile.With key circular blade 182 is rotatably installed on the axle 184, this blade can slide along axle in the axial direction, and spring 186 pushes away blade facing to bed plate 178.Circular clamping device 188 and 190 1 sides at blade, these clamping devices are securely fixed in yarn and supporting cotton rope in the groove on the bight of mandrel.Axle 184 rotatably mounted these clamping devices, but these clamping devices are not subjected to the torsional moment from axle 184; And these clamping devices can slide along axle in the axial direction.These clamping devices can freely rotate, and are irrelevant with the axle that is driven by the motion of cotton rope.Spring 192 and 194 is pressed to clamping device 188 and 190 respectively the bight 196 and 198 of mandrel 74 respectively.Clamping device is securely fixed in cotton rope (and be welded on this cotton rope yarn) in the groove on the bight of mandrel, and blade is applied to a dissection power on the surperficial yarn simultaneously, and it is cut off.Axle 184 be can be rotated to support in the housing 200, and motor 202 (partly illustrating) drives this axle rotatably.Fig. 7 B shows the figure that at a groove 197 in the bight of mandrel 74 one has amplified.The degree of depth of this groove is 199.The degree of depth 199 can the thickness of cotton rope about 25% and 75% between, so that it is firmly fixed, and in the process of welding, still can not disturb the surface 148 and 150 of soldering tip, and still support yarn, be not subjected to the restriction of mandrel, be used for after welding, transporting along mandrel.
When advancing the yarn that welded and cotton rope along mandrel 74, facing to rotation of blade 182 pulling yarns, when yarn was cut between blade and bed plate, blade cut off yarn.Fig. 8 shows blade 182, bed plate 178, the schematic cross sectional view of mandrel 74 and yarn 40.Yarn is brought into intersection area 206 between blade and the bed plate with the direction of arrow 204, cut yarn at this position blade.In order to cut off nylon 6-6 yarn effectively, have been found that, scribbling amorphous diamond at periphery (can be by Tetrabond, Inc. obtain, it is at Rockaway, the blade material of the tungsten carbide of the C-11 level sub-micron Multiarc of NJ, the subsidiary of Inc.) gets fine facing to the bed plate work of D2 high-speed tool steel.Referring to Fig. 7 C, the part of the blade that applies is part 203,205 and 207 preferably.Unbodied diamond coatings has the Vickers hardness of about 6000 units.In addition can work well coating be the further coating of the titanium nitride of 2 microns the coating of titanium carbide chemical vapour deposition and 2 microns.Such coating can have the Vickers hardness of about 2600 units.In order to improve the life-span on blade and bed plate surface, have been found that, adopt a coating felt pan 208 water and a kind of yarn coating, such as a kind of alkylphosphonate, cooling lubricant to be applied on the blade face be useful, make this felt pan keep moistening by adopting intravenous drip systems 209 or similar device.Such coating can be Zelex NK, and it can be by at Wilmington, and the E.I.DuPond Co. of DE obtains, and it is sold as a kind of antistatic yarn coating.It is mixed with distilled water, is 0.5-2.0% with the percent by volume at the mixture floating coat.Believe, the direction rotation that blade is advanced at yarn, and a circumferential speed rotation of the speed of under blade, passing through with a little higher than (approximately 3-10%) yarn, blade is the most effective cutting off aspect the yarn, and does not have undue wear.Believe that low speed can reduce rate of depreciation, and this direction of rotation makes that the increase of any yarn tension drops to minimum in the cutting-off process.This has caused the shear action of comparing with sawed-off effect, and on sawed-off, the circumferential speed of blade is than the speed that yarn advances faster (approximately wanting big 500-1000%).Yet, when blade rotates in the opposite direction and/or at full speed rotates with the side that advances with yarn, can occur and can like this, sawed-off effect occur by the cut-out that is subjected to.When adopting shear action, cut edge angle 210 on blade (Fig. 7 A and 7B) preferably is approximately 75 degree (for sawed-off 45 degree that act as), and the root-mean-square value (rms) that is coated with the coating on part 203,205 and 207 at the quilt of cut edge is about 1-2 microinch.Though described a kind of static bed plate and the blade of having adorned spring, being used for a blade and bed plate forces together, and loads onto spring and also is fine but be fixedly mounted in blade 182 on the axle 184 and bed plate 178 can be moved on mandrel 74 and face toward blade 18.
When the yarn on the cut-out mandrel, can cut off the yarn on the opposite flank at identical lengthwise position place of mandrel with two blades (and at the same time), because the cutter on relative side does not disturb each other.Also can cut off with the cutter of separating in the vertical along mandrel.This is possible because clamping device is securely fixed in cotton rope and the yarn loaded onto in the groove on the bight of mandrel, this be since in the process of cutting off cutter little tension force is applied on the yarn.Clamping device resists this tension force, and cotton rope is pulled out groove.Fig. 9 shows two cutters that have blade 212 and 214, and they can be in the identical lengthwise position on the relative side of mandrel 74.In these cases, when cutting off, the clamping device 216 of rotation and the 218 fixing yarns that cut off by blade 212, and clamping device 220 and 222 is fixed for the yarn of blade 214.Shown clamping device and alignment blade, if but they are set at the upstream side that separates and be positioned at contiguous blade with blade, the cut intersection area of more close yarn 206 (see figure 8)s, and they also can be worked.
Figure 15 shows two mandrel components 215 that have cutter, and these cutters can be shared the CD-ROM drive motor that is used for making the cutting axis rotation.In a kind of the setting, motor 224 can drive for the cutter shaft 230 of mandrel 232 with for the axle 226 of mandrel 228 by belt and pulley apparatus (not shown).In another kind is provided with, can be being installed in for the blade 234 of mandrel 228 and blade 236 on the identical axle 238 for mandrel 232, motor 242 drives this axle by a belt and pulley apparatus 240.Mandrel and this setting that is mounted to the cutter on the carriage 107 have obtained a kind of assembly cheaply of compactness, and it can easily keep in repair and maintain processing.In this was provided with, at first the identical lengthwise position at arrow 260 was carried out twice cut-out on each mandrel, then once cut off on each mandrel in the position of arrow 262, subsequently, once cut off on each mandrel in the position of arrow 264.On a given mandrel, can change this cut-out of 2: 1: 1 order, and not influence the generation of the wool knitting yarn on mandrel; For example, cut-out order in addition can be 1: 2: 1 or 1: 1: 2.More or less cutter motor is arranged, and other setting of belt drive and cutter shaft is possible, and can not influence the operation of quality and two mandrel wool knitting yarn assemblies 215.
Referring to the bottom of Figure 10, a plurality of wool knitting yarn guiding belt pulleys are arranged on the twin-core shaft assembly.For mandrel 228, belt pulley 244 and 246 guides the wool knitting yarn that come out by mandrel bight 248 and 250 respectively; Belt pulley 252 and 254 guides the wool knitting yarn that come out by mandrel bight 256 and 258 respectively.For mandrel 232 a similar belt pulley setting is arranged.Each belt pulley has a groove, holds wool knitting yarn, makes the wheel hub of that side of cotton rope towards belt pulley, and makes the periphery of lint towards belt pulley.Each twin-core shaft assembly is made 8 wool knitting yarns.
Figure 11 is the detail view that is shown in the wool knitting yarn formation assembly 38 of Fig. 1.Show the twin-core shaft assembly 215 of Figure 10 9 positions,, provide 72 wool knitting yarns such as transversal the position 54,56,58 and 60 that forms the width of assembly 38.Forming assembly 38 has for the common inlet squeezing roller of cotton rope with for the common inlet squeezing roller of fine hair yarn for all 72 wool knitting yarns, and for 72 wool knitting yarns common outlet squeezing roller is arranged.Referring to Fig. 2 cotton rope inlet squeezing roller is discussed, the feeding roller 92 that is driven that this inlet squeezing roller is shown as idle running feeding roller 90 and is rotated by motor 93.Referring to Fig. 2 yarn inlet squeezing roller is discussed, the feeding roller 100 that is driven that this inlet squeezing roller is shown as idle running feeding roller 98 and is rotated by motor 101.Referring to Fig. 2 wool knitting yarn outlet squeezing roller, the outlet roller 111 that is driven that this outlet squeezing roller is shown as idle running outlet roller 109 and is rotated by motor 113 are discussed.Be used for the wool knitting yarn guide roller 266 that wool knitting yarn is directed to drum assembly 49 (seeing Figure 1A) is in the top that forms assembly 38.
Combination driving for the wind of mandrel also can be arranged.For example, motor can drive 5 pairs of winds for 5 twin-core shaft assemblies, and motor can drive 4 pairs of winds for remaining 4 twin-core shaft assembly.Being provided with like this can be adopted a belt and belt pulley system, as among Figure 11 arrow 268 places partly illustrate.Framework 75 is fixed together all parts of wool knitting yarn assembly 38.
In drum assembly 49, a plurality of wool knitting yarn guiding pieces are arranged, be used for accurately a plurality of wool knitting yarns being directed on the base fabric, and be directed to ultrasonic horn below, be used for welding.Figure 12 A show be used for weld interval closely first wool knitting yarn welding soldering tip 270 of many wool knitting yarns and second soldering tip 271 amplification side view; And be used at interval closely many wool knitting yarns guide a wool knitting yarn of aiming at first soldering tip 270 to weld guiding piece 272.Each soldering tip is put into one and is similar in a weld assembly of the sort of assembly shown in Fig. 5, is used for yarn is welded on the supporting cotton rope on the mandrel.Diametrically each soldering tip is applied active force, such as shown in figure for soldering tip 270 with arrow 274, facing to base fabric substrate 50 with facing to cylinder 52 extruding wool knitting yarns.First soldering tip is used to a wool knitting yarn and spots weld slightly on the base fabric, keeps simultaneously by guiding piece 272 determined alignings, and soldering tip 271 can be applied to more energy on the wool knitting yarn that remains heat, and it is attached on the base fabric securely.The adduction effect of two soldering tips can be added to lot of energy in the welding to wool knitting yarn apace.Should keep the distance 273 between soldering tip 270 and 271 shorter, so that obtain the interests of this effect, but this distance also provides the regular hour, is used for making the heat from first soldering tip to penetrate the supporting cotton rope.Under the situation of the low speed that does not need to add apace big energy, may only need first soldering tip.When surperficial yarn being welded to when wool knitting yarn forms on the cotton rope on the mandrel, this a pair of soldering tip technology also may be useful.For example, in Figure 13 A-E, illustrate in greater detail soldering tip 270.Soldering tip in Figure 13 A has four Y-pieces 276,278,280 and 282, each is designed to be assemblied between the lint on the single wool knitting yarn, and contacts with the supporting cotton rope in the bottom of lint.Interval 284 between the Y-piece is identical with the interval of the desirable wool knitting yarn on finished carpet.For the interval of different wool knitting yarns, can use to have corresponding Y-piece different soldering tip at interval.In the height 286 of Y-piece and the finished carpet on the wool knitting yarn of desirable maximum lint height the maximum length of lint corresponding.Soldering tip have among Figure 13 B shown in length 288, this length and ultrasonic amplitude, frequency, and the power of driver is relevant.Figure 13 C shows the front end 290 of Y-piece 282 and the typical detail of tail end 292, shows a little radius 294, to help to guide smoothly wool knitting yarn below soldering tip.Figure 13 D shows the another kind of possible shape of Y-piece, and radius 294 ' stretch on the length of Y-piece wherein like this, when the slip underneath of wool knitting yarn at soldering tip, is little by little exerted pressure.Other shape also may be favourable, and first soldering tip 270 can have the shape different with second soldering tip 271.Figure 13 E shows the typical detail of shape at the top 296 of Y-piece 282, and it has the surface 298 of a concave, and this surface keeps this cotton rope not slide into the side in welding process along the length 288 guiding supporting cotton ropes of Y-piece, skids off below Y-piece.The surface of this concave entire radius 290 and 294 ' on stretch, the track of cotton rope that helped to make wool knitting yarn before the pressure of soldering tip and vibration are applied on the wool knitting yarn is below soldering tip.
Referring to Figure 12 B, guiding piece 272 has a plurality of slits, and such as slit 300, it has a very narrow width 302, this force on the wool knitting yarn lint towards each other, and force lint the supporting cotton rope above.Be shrunk to an interval at the interval that equals the wool knitting yarn in last carpet assembly, wanted for the slit of many wool knitting yarns.These slits are directed to soldering tip to the wool knitting yarn of appropriate intervals, and this soldering tip has the Y-piece at same interval, and this soldering tip nestles up the end 304 of guiding piece 272.Wool knitting yarn is with surperficial about 15 these soldering tips of angle convergence of spending for cylinder, and like this, the surface of the concave in soldering tip helps to make the track location of wool knitting yarn.On Y-piece, for the lint that is directed into the wool knitting yarn on it separately, thereby row's lint passes through along a side of a Y-piece, and another row's lint passes through along the opposite side of Y-piece, and exert pressure to it above the supporting cotton rope in the top of Y-piece 296.In a side of soldering tip 270, plow-shape spare 263 is inevitable shift the wool knitting yarn of previous welding onto side, thus single lint can not be trapped within the wool knitting yarn that is directed below, and soldered below soldering tip.On the relative side 308 of soldering tip 270, usually there not be previous soldered wool knitting yarn to exist, be installed on the guiding piece 272 so support finger 310 to one, be bearing in the outside lint on that side of soldering tip.Finger 310 contiguous soldering tips 271 stretch, and cross soldering tip and stretch, and are upwards fixing lint, cool down up to welding.If outside lint is not supported by finger 310, then find, process in heating neutralizes when soldered wool knitting yarn cools off, outside lint tends to downward covering, thereby in last carpet assembly this row's lint produce one and adjacent one arrange different can observable " striped ", even such striped is arranged after the shearing of lint, like this, carpet has a defective that is called as streak.
After welding on cylinder 52 was finished, cylinder continued the distance of a weak point of rotation, and a plate 265 being contained in below the guiding piece 300 is pressed along the direction of arrow 267.This plate 265 be crushed on be directed but also not soldered wool knitting yarn and soldering tip 270,271 below, like this, can be guiding piece, wool knitting yarn and soldering tip raise up, and are used for wool knitting yarn is cut off, the carpet of finished product is removed, and a new base fabric is penetrated on the cylinder.Can be guiding piece, wool knitting yarn and soldering tip are fallen, and plate is extracted out, thus wool knitting yarn is in the position facing to new base fabric, below the soldering tip that is prepared for welding, restarts to make the process of carpet.
Figure 14 shows a side view of belt component 311, and this assembly is to substitute for one of drum assembly, in this assembly, a plurality of rollers 312,314,316 and 318 are supporting endless base fabric substrate 50 for no reason, rather than a single swift 52 shown in the image pattern 1A.Like this, can provide a big base fabric ring, be used for making a long carpet, and the expense of neither one major diameter cylinder.Roller 316 can be reorientated easily, changes the length of this ring, to adapt to the size of carpet tile.The embodiment of Figure 14 also crosses the wool knitting yarn group on the length of roller 312, and this roller keeps transfixion, and is different with the embodiment of Figure 1A, and wool knitting yarn keeps motionless there, and cylinder crosses the distance between the wool knitting yarn group.Travelling carriage 320 is carrying wool knitting yarn directing assembly 322 and 324, the first weld assemblies, 326, the second weld assemblies 328, and wool knitting yarn welding guiding piece 272 '.Component class shown in these two weld assemblies and Fig. 5 seemingly still, has the soldering tip of Figure 13 A.Actionless bar 330 and rotatable threaded bar 332 are supporting travelling carriage 320, and bar 332 is driven by a motor (not shown) that is mounted; This threaded bar engages with a threaded nut in travelling carriage 320.Motor 334 is by a belt and belt pulley system 336 driving rolls 312.One or more in the roller 314,316 and 318 can be in the middle of protuberance a little, guarantee the fixing position of track on supporting rollern of base fabric substrate.For an edge guide member of base fabric,, also can help the location of track such as edge guide member 338.Framework 340 is supporting all parts of belt component 311.When the operation of the system of Figure 1A but when adopting belt component 311, may wish belt component 90 is orientated to and shown wool knitting yarn 42,44,46 become 90 degree with 48 direction, thereby they can be aimed at the direct of travel of the travelling carriage 320 that laterally moves, like this, the angle of wool knitting yarn can not change in the process that laterally moves.
Belt component 311 can move with many groups wool knitting yarn, as described with reference to Figure 1A, perhaps, it can only move with one group of wool knitting yarn, this wool knitting yarn transversal the whole length of roller 312 move in the horizontal, roller 312 is used as the ultrasonic anvil block for this assembly.Like this, only need to make considerably less wool knitting yarn, and only need considerably less surperficial yarn supply volume and supporting cotton rope volume.This forms a kind of package system of carpet cheaply, and still, the productivity ratio of this system is much lower in the system shown in Figure 1A.For some situation, this may be preferred.For example, if wish to make carpet in the place of sale, the low cost of this method of operation and compact advantage may be special hope.
Figure 15 shows the side view of a winding assembly 342, and this assembly is that drum assembly 49 and a kind of of belt component 311 of being discussed substitute.In this winding assembly 342, the necessary many wool knitting yarns of the whole width of carpet are directed on the welding roll 344, and they are connected with the base fabric substrate 50 of an elongated coil there, and are soldered on this volume base fabric, produce a whole volume carpet; Perhaps, if the supply that provides not have terminal can be provided base fabric, the supply that provides not have terminal can be provided the supporting cotton rope, and, can on flywheel, cut off carpet in the horizontal; Can make the process of carpet continuously.Can twine rolling to carpet, or can cut into carpet the length of interruption, and be piled up.If wish to make 12 feet full duration carpet, the number of the wool knitting yarn assembly 38 shown in Figure 1A must be increased to 10 times, and about 720 wool knitting yarns are provided, and correspondingly increase the number of surperficial yarn creel, such as 62 and the number of supporting-line rope support, such as 68.In addition, can add additional twin-core shaft assembly to wool knitting yarn and form on the assembly 38, can only need five assemblies 38 that improved so like this.
In Figure 15, winding assembly can adopt the top side solder technology of discussing, in this technology, wool knitting yarn be directed to the fork-shaped soldering tip below, maybe can adopt bottom side welding, as will discussing with reference to Figure 15 and 16A-D.Winding assembly 342 comprises a welding roll 344; A plurality of weld assemblies, such as 346,348,350 and 352; Base fabric substrate support device 353; Wool knitting yarn directing assembly 354 and 356; Welding roll CD-ROM drive motor 358; Carpet driving rolls 360 and carpet compression assemblies 362; All these is attached on the framework 364.
At first guiding is from the wool knitting yarn of wool knitting yarn assembly 38 on four isolated height in directing assembly 354, and directing assembly 354 is separated wool knitting yarn, near they desired last intervals in carpet backing and installation system.Each root in four adjacent wool knitting yarns is gone up at various height, tangles in order that handle easily and prevent.Guiding piece 354 comprises a motionless roller of the slit that has different in width; This roller can periodically revolve a part that turns around, so that make wearing and tearing evenly.Wool knitting yarn is remained on the height that they are directed in the directing assembly 356, and the wool knitting yarn that obtains in carpet in this directing assembly 356 being wanted is to the last interval of wool knitting yarn.Figure 16 A shows the passage in directing assembly 356, such as lower channel 363.Each passage has the inlet that is cut into fillet, such as the inlet in passage 363 365, lint, to 367,369 and 375, becomes as shown in the figure parallel orientation by their orientation guide of band angle such as lint.
Importantly make the angle of wool knitting yarn downward, the fillet part 373 of crossing the inlet 365 that is cut into fillet with angle 371, like this, lint " becomes the fan-shaped " that scatters when lint enters guiding piece 356, and lint can not tangle with other lint on the wool knitting yarn.This angle should be between about 5-45 degree, and is best, is approximately 20 degree.Importantly, when wool knitting yarn enters guiding piece 356, wool knitting yarn is remained apart, and they can not tangled each other.Realize that this point is the staggered path by a plurality of height that enter guiding piece.For example, to 367 and 375, per the 4th wool knitting yarn is in identical height for the lint that goes out as shown, and they separate enough far away, makes lint 367 can not tangle with lint 375.Adjacent wool knitting yarn 367 and 369 in the vertical directions are staggered separates enough distance, thereby lint 367 can not tangle with lint 369.Many round bars, such as bar 377 and 379, separated opening in the front of guiding piece 356, gone up facing to the slight scrubbing brush of lint (only showing two) at various height, prevents that they depart from orientation upwards when wool knitting yarn enters guiding piece 356; This guaranteed the cotton rope of wool knitting yarn will be in the passage 363 of guiding piece 356 centering.
Figure 16 C shows another width of cloth figure, how to illustrate wool knitting yarn is directed in the groove in welding roll 344 by the passage in the guiding piece 356.For example, the wool knitting yarn 48 that comprises supporting cotton rope 386 and first row's lint 388 and second row's lint 390 is downwards by passage 363, and towards fin 391, this fin is one of a plurality of fins on plow-shape spare 370.For the sake of clarity, omitted wool knitting yarn in adjacency channel.Formed passage 363 between parallel plate 392 and 394, these plates stretch downwards, cross the end 396 of the bottom of passage 363, and enter the groove on the roller 344.Plate 392 stretches groove 376, and plate 392 stretch groove 376 '.Rib 374 stretches between the end of plate 392 and 394, and these plates stretch into groove.Fin 391 is aimed at rib 374, and stretches along passage 363, before two row's lints 388 and 390 reach rib 374 they is separated.Fin 391 has a tip 398, and facing to the direction that wool knitting yarn advances, row separates them through out-of-date help when lint.The surface 400 of a concave is arranged at the top of rib 374, holds the supporting cotton rope, and keeps this cotton rope can not fallen by the top of rib, drops in the adjacent groove.If in last carpet backing and installation system, be changed, can change directing assembly 356 and welding roll 344, and substitute with guiding piece that new interval is arranged and roller by the interval (pitch) of a wool knitting yarn to another root wool knitting yarn.If provide necessary number in primary importance, can not need to change guiding piece 354 for the slit of wool knitting yarn.
Figure 16 D shows a section that passes welding roll 344, how shows base fabric 50 at wool knitting yarn, such as wool knitting yarn 48 and 46, and last location, and ultrasonic horn 384 welds how facing to rib 374 and 374 ' they are pressed together.Only adopt a ultrasonic drivers and amplifier, soldering tip 384 just can once weld many wool knitting yarns; For example, believe, can once be welded to eight wool knitting yarns on the base fabric 50 reliably with single soldering tip/driver/amplifier.
Figure 17 A shows one and is used for from the typical soldering tip 384 of the many piece wool knitting yarns of back of the body surface soldered on winding assembly 342.The edge 402 of soldering tip 384 and 404 can stretch crosses the soldering tip body, forms face of weld 406.Length 408 of face of weld 406 (seeing Figure 17 B) and ultrasonic amplitude, frequency, and the power of driver is relevant, preferably there is the molded lines of radius 410 on the surface, as seeing at the enlarged drawing of Figure 17 C.Radius 410 helps guiding base fabric and the wool knitting yarn below soldering tip, and this soldering tip pushes them and they are welded together simultaneously.Figure 15 illustrates a plurality of weld assemblies, be used for finishing at interval welding reliably closely.A plurality of weld assemblies of aiming at assembly 346 spot weld more than first group isolated wool knitting yarn on the base fabric slightly, and can disturbance by directing assembly 356 resulting alignings on the rib of welding roll 344.A plurality of weld assemblies of aiming at assembly 350 are welded to first group of many wool knitting yarn on the base fabric securely.A plurality of weld assemblies of aiming at assembly 348 spot weld more than second group isolated wool knitting yarn (being made up of all remaining wool knitting yarns) on the base fabric slightly, and can disturbance by directing assembly 356 resulting alignings on the rib of welding roll 344.A plurality of weld assemblies of aiming at assembly 352 are welded to second group of many wool knitting yarn on the base fabric securely.
After welding, have the base fabric of the wool knitting yarn of being loaded onto, be a kind of carpet backing and installation system 412 now, walk around roller 414, and walk around driving rolls 360.Compression assemblies 362 can be pressed to driving rolls 360 to idle roller 416 with being pivoted, is used for driving carpet backing and installation system 412 by winding assembly 342.Subsequently, carpet backing and installation system is crossed framework 364, is used for further processing.
Figure 18 shows the layout drawing of a complete carpet manufacturing system, and this system comprises that a plurality of wool knitting yarns form assembly 38 and a winding assembly 342.In the layout drawing that illustrates, five wool knitting yarns form assembly 38a, 38b, and 38c, 38d and 38e are configured to each 144 wool knitting yarns are provided, for 12 feet wide carpet products, 720 wool knitting yarns altogether.These wool knitting yarns are sent to a winding assembly 342a with a parallel row 418, and this winding assembly is designed to the width of transversal this assembly and accepts 720 wool knitting yarns.Provide a volume base fabric substrate 420.12 feet wide base fabric substrate 50 is passed through on the roller 422 that one 90 degree is turned, and is sent to winding assembly 342a, is used for being welded on the wool knitting yarn row.Each wool knitting yarn forms assembly by a yarn creel supply, and such as the coil holder 424 for assembly 38a, this coil holder is for fixing three yarn ends of as many as of each wind that form in the assembly, and perhaps 108 operation volumes are connected volume with 108; And by a supporting-line rope support supply, such as the coil holder 426 for assembly 38a, it has 144 operation volumes to be connected volume with 144.Be provided with traditional coiled material accumulator 428 and 430, in order that continuous operation is provided.Carpet backing and installation system 412a is wound in a volume in end 432; Floor covering is accumulated, and is used for segmentation to be transported in the storage area 434 product processing line.The whole process of equipment control device 405 controls.Guidance panel 407 allows that the operator imports.The controller 409,411,413,415,417 and 419 that scatters is controlled at the ultrasonic system on wool knitting yarn formation assembly and the winding assembly.
This wool knitting yarn forming process is particularly suitable for adopting prestained yarn (yarn of solution-dyed), because required institute yarn creel can be than needed significantly little with traditional carpet lint operation.In the time must changing coil holder for the change for each color of carpet, a little coil holder is an advantage.When prestained yarn was used to the wool knitting yarn carpet, carpet backing and installation system must because other step of bulking is provided in traditional carpet systems, such as carpet dyeing operation and kiss-coating drying process, be unnecessary through a bulking process of separating.Figure 19 shows special last machining production line, and it comprises 440, one inspections of 438, one traditional shears of device 436, one cooling chambers of 435, one bulk heating furnaces conveying device 442 that volume is opened, and a lap former 444.After reeling, the floor covering of finished product is stopped up by a banding machine 443, and is put on the estrade 445, waits ready for delivery.Be provided with traditional coiled material accumulator 446,448 and 450, in order that continuous operation is provided.Described bulking process and device in common pending application RD-7035-P1, this application here is incorporated into and is used as reference.
The assembly 38a-e that wool knitting yarn among Fig. 2 forms among assembly 38 and Figure 18 requires some special control to consider, can these considerations the most clearly be discussed referring to Fig. 2.In order to begin and stop the ultra-sonic welded process, and produce acceptable product, the amplitude of ultrasonic horn and the pressure of soldering tip must be along with the rising of the speed of wool knitting yarn and declines and are risen and descend.Yarn must be monitored and be controlled in service in stable state, the tension force on supporting cotton rope and the wool knitting yarn, and monitor ultrasonic power and control it as steady state value.For example, the ultrasonic controller 409 of distribution (forming assembly 38 with wool knitting yarn in Fig. 2 illustrates) be connected to ultrasonic drivers 136 and 136 ' on, and these drivers be connected to soldering tip 134 and 134 ' on.Machine controller 405 is connected to the controller 409 of distribution and with on other parts shown in the helical segment, will discusses below.
Except those parts of having discussed with reference to Fig. 2, wool knitting yarn formation assembly is also included within four motors on the cutter device 86; Voltage is arranged to pressure regulator 452 and 454 respectively for weld assembly 78 and 80, cylinder body 142 and 142 ' and ultrasonic drivers 136 and 136 '; For cylinder body 94,102 and 119 valve 456,458 and 460 are arranged respectively; And for the tensometer 462 of monitoring the tension force on one of wool knitting yarn of having finished with in order to monitor corresponding cotton rope, such as cotton rope 30, on the tensometer 464 of tension force.
Motor 113 is to be used for cotton rope is pulled through mandrel 74 along the oncus of mandrel, and is used for being soldered on the cotton rope and spurring wool knitting yarn after being cut off at yarn.When starting wool knitting yarn and form assembly, the speed of servo motor 113 is by the resolver monitoring of an installation, and the active force of cylinder body 142 and 142 ' applied increases, and the horn amplitude of ultrasonic drivers 136 and 136 ' applied increases.Active force and amplitude are all with the linearly proportional increase of climbing speed of the speed of motor 113.Consider that soldering tip and cylinder body have operating lag, some little hysteresis also can be arranged, purpose is that soldering tip always is welded to all yarns on the cotton rope, and does not have excessive welding and damage the fiber of any yarn.These active forces of machine controller 405 control, this controller control are passed to each voltage on each weld assembly to pressure regulator, such as 452 and 454, individual signals.These amplitudes of machine controller 405 control, this controller control is passed to each ultrasonic drivers on each weld assembly, such as 136 and 136 ', signal.When motor 113 rose to the speed of a stable state, machine controller was kept stable welding condition by amplitude control break success rate or energy control.Active force is retained as constant, and changes amplitude, so that the power that remains unchanged for each ultrasonic drivers and soldering tip.The efficient that has been found that ultrasonic drivers is along with this unit in continuous operating process is heated and changes.This variation of efficient has been proofreaied and correct in the change of the amplitude that holding power is constant, thereby obtains stable welding.Soldering tip itself has also been seen the heat temperature raising of attending the meeting, can lead by pipeline 455 and 457 pairs of cooling air, and the suffered temperature of restriction soldering tip face of weld rises; Also can be the cooling air guide towards driver.
When stopping wool knitting yarn and form, machine controller is begun to change by constant power control, realizes and starts opposite step, along with the decline of the speed of motor 113 lowers amplitude and active force.The basic value of amplitude is the amplitude of just being sampled before stopping to take place, because amplitude changes along with the carrying out of constant power control.Wool knitting yarn speed is about 3-5 second by the typical time that about 0-15 YPM rises.Have been found that in some cases, when starting and stopping, only need change active force, and amplitude remains unchanged, but preferred operation is to change active force and amplitude simultaneously.
Be directly coupled to drum assembly 49 or belt component 311, or the wool knitting yarn on the winding assembly 342 forms in the running of assembly, each driving in these assemblies is also spurred wool knitting yarn, so, must use for each wool knitting yarn and form assembly, such as 38, the tension force of single tensometer 462 monitoring wool knitting yarns.Subsequently, the speed of machine controller 405 governor motors 113 keeps the tension force of wool knitting yarn constant.This has prevented overtension and loose excessively, and these may be upset and form the wool knitting yarn process, and makes wool knitting yarn disconnected.Similarly, also must use the tension force that forms the single tensometer 464 monitoring cotton ropes of assembly 38 for each wool knitting yarn, the speed of machine controller 405 governor motors 93 keeps the tension force of cotton rope constant.Tensometer 462 and 458 is set is for before yarn is carried out the welding production wool knitting yarn and afterwards the circuit of same cotton rope is measured.
Yarn feeding roller motor 101 and wind motor 126 be by machine controller 405 control, like this, remains unchanged at the tension force that is sent to mandrel 74 and be wrapped in the yarn 40 on the mandrel.According to the indication from each operator of guidance panel 407 (seeing Figure 18), controller is set speed of wrap, the number along cotton rope per inch cotton rope that obtains being wanted.The speed of motor 101 is configured to be proportional to the speed of twining motor 126, so that obtain the tension force wanted based on successive approximation method.If be ready, can on the yarn between feeding roller 92 and the peg or spindle entrance point 120, use a tensometer, help to form tension force, and control this tension force, still, have been found that fixed speed ratios can work fine.
Shown mandrel 74 and be a kind of structure of hollow, supporting cotton rope (and/or carrying cotton rope) is by the center in the wind of surperficial yarn.The " mandrel structure of other " hollow can be worked well equally.Figure 20 A shows the star mandrel 466 that has three arms, and supporting cotton rope (or carrying cotton rope, if all supporting cotton ropes are soldered to the outside that is wrapped in the yarn on the mandrel) is by the arm of mandrel, such as 470 and 472, between depressed part, such as 468.Cotton rope by the center to oncus, transversal each other.Be provided with cutter round mandrel, such as 474, and ultrasonic horn, such as 476.Figure 20 B shows a kind of mandrel 478 of star four arms, in this mandrel, by the center to the cotton rope path of oncus preferably not with the centrally aligned of arm.The another kind remodeling of mandrel has been shown in Figure 20 C, and in this mandrel, 480 of mandrels are made two wool knitting yarns, and the guiding tube 482 and 484 for cotton rope is arranged.Can be arranged perpendicular to the cotton rope path to the surface of oncus 486 and 488,, make the twisting minimum of cotton rope if cotton rope has flat or oval-shaped side.Figure 20 D shows a kind of single wool knitting yarn mandrel 490 that has along the slit 492 at an edge, this slit guiding supporting cotton rope, and the groove that cuts off usefulness is provided.Figure 20 E shows the side view of the mandrel of Figure 20 D, shows the end 494 of the inclination on an edge of mandrel, helps yarn is transported on the ultrasonic horn, because the supporting cotton rope that does not engage with yarn at this edge is used for help and transports this yarn.In another mandrel embodiment that has just discussed, the cutting blade that illustrates does not need bed plate to realize the cut-out of yarn.Figure 20 F shows the side view of the mandrel 496 of an entity.By source that separates 498 and 500 feeding yarns about mandrel 498 rotations.Like this, can supply cotton rope 502 and 504 as shown in figure, rather than along mandrel, thereby this mandrel needs not be shape hollow or star that has for supporting cotton rope or carrying the passage of cotton rope.
Though described the present invention by making cut pile carpet, wool knitting yarn forms assembly 38 and can match with the mandrel component that is suitable for making annular fine hair wool knitting yarn.Such mandrel component can be based on annular fine hair wool knitting yarn device and process, the common pending application No.08/331 that these devices and process have been applied on October 28th, 1994, described in 074, this application here is incorporated into and is used as reference.In this case, may need more mandrel, because a mandrel is only made an annular fine hair wool knitting yarn,, thereby in carpet, may only need less wool knitting yarn just can obtain and the identical covering of cutting off of fine hair wool knitting yarn although every annular fine hair wool knitting yarn has two row's rings.Can give as described carpet annular fine hair wool knitting yarn and one of form in the assembly 49,311 or 342, form an annular fine hair wool knitting yarn carpet.Can adopt the described guiding of fine hair wool knitting yarn and the solder technology that are similar to for cutting off.Can adopt a different last machining production line for annular pile carpet, this depends on the purposes that carpet is planned.
