The yarn feeding device that the circular knitting machine of finished yarn is used can be used for acting on separately on the different circular knitting machines of pin and casting spring needle together.This device has one to be contained in rotating circumference yarn feeding part on the support that is fixed in truss, drives the buncher of this device usefulness on the support in addition and is used for guide and/or the detection agency that the yarn feeding part leads in/out yarn.For the low volume of the cost that makes device is little, adopt known stepper motor to drive, at least also be provided with one on the support and realize fricton-tight yarn feeding with periphery by motor-driven yarn feeding part, this part has also independently that yarn guides and detection agency simultaneously.
Description
The present invention relates to a kind of yarn feeding device, this device can be used for the textile machine of finished yarn, for example uses knitting garden machine that acts on pin separately or the knitting garden machine that uses casting spring needle together; This device has a yarn feeding part that utilizes its garden week yarn feeding, and this part is installed on the support on the fixing truss, and can rotate.Be installed with on the support and be used for guide and/or the detection agency that yarn was introduced and/or drawn to the yarn feeding part; This device drives by a rack-mount variable-speed motor.
Use in the spininess type acts on separately on the knitting garden machine of pin, for nonslipping yarn being provided for each knitting system, known method is, a yarn feeding part that is the yarn feeding barrel shape is set in each knitting system, yarn to be fed repeatedly is wrapped on this yarn feeding tube, forms a yarn reel.On the yarn feeding tube, the speed that yarn is introduced and drawn equates.All yarn feeding tubes all pass through an endless-belt transmission around machine run, and the shape of this belt generally is hole shape band or cog belt.Because the cause of affiliated belt guide, this endless-belt structure around machine run is very complicated.
In addition, because all yarn feeding parts that are the yarn feeding barrel shape are all by the endless-belt transmission, so whole yarn feeding part all can only provide the yarn of same quantity.Under certain condition of work, for example when weaving the product that has decorative pattern, each knits the yarn that a little needs varying number.Therefore above-mentioned yarn feeding device is inapplicable for this purpose.Must use for example so-called memory type yarn feeding device, its reel for yarn above yarn feeding tube can pull out from the head, by the transmission of connecting or cut off the yarn tube size of head is remained between two limiting values.When excessive traction yarn, to knit a rate of tension of locating yarn and only can regulate by Yarn Brake, this is difficult to accomplish on some yarn or is difficult to do accurately.
This memory type yarn feeding device also is known (seeing Germany exhibition patent specification 1635899), its each yarn feeding tube is all by a motor single driving, its structure is as follows: the garden cylindricality reel of yarn feeding tube constitutes the rotor of motor, and the supporting of rotor is positioned at the inside of reel.Motor and power supply link together, and are subjected to the control of a microswitch; Microswitch is subjected to a manipulation with the contacted garden of reel for yarn dish, so just can connect or cut off motor power, and make reel for yarn less than or greater than a certain definite size.Can not accomplish adjusting in this way to reel garden circular velocity.
Another kind of yarn stores and supplies to feed device (seeing Germany exhibition patent specification 2350979) also is known, this device has electric motor driven yarn storage tube, the revolution adjustment structure of its mechanism is as follows: motor is in the number of moving part scope, moment of torsion with substantial constant, the size of the moment of torsion of this driving yarn storage tube just can be regulated the rotating speed of this device corresponding to the size of reel for yarn with because of motor orders about the size of the power that reel for yarn axial displacement changes by the method.The principle of this device institute foundation is: utilize yarn storage tube to go up the variable resistance to sliding of reel for yarn as the parameter that directly influences revolution.But this resistance to sliding is relevant with the character of employed yarn.In addition, this adjusting is very rough in essence.
Also has a kind of known yarn feeding device (seeing German Democratic Republic patent specification 44941) that uses on the knitting garden machine that acts on pin separately that is applied in.In this device, each knits the variation of a little going up the yarn requirement is by programme controlled.For this purpose, this yarn feeding device has a conveying roller that is twining or twining yarn on it on the part circumference, and this roller can just constitute the rotor of motor by Motor Drive or itself.In this device, roller has the surface of delivered yarn fricton-tightly, and by certain means, guarantees that the revolution and the syringe of motor is synchronous automatically.Motor can be stepping motor or synchronous motor.But the document is disclosed only is the principle of this yarn feeding device; As for its detailed structure how, then not open.
Above-mentioned yarn feeding device with motor single driving yarn feeding part has following advantage: can abandon round the driving belt of whole circular knitting machine circumference.But on the other hand, the cost of this yarn feeding device is relative again with volume higher and bigger, and this is very disadvantageous for super spininess type knitting machine (for example 144 pins).
Task of the present invention is, makes a kind of general yarn feeding device, and this device has by the motor single driving, corresponding each knits a little yarn feeding part; Can accurately satisfy various instructions for uses, and can control separately and regulate the yarn feeding amount; It is low and take up an area of few characteristics to have cost in addition.
The solution of above-mentioned task is the yarn feeding device that this specification begins described type, it is characterized in that, motor is a known stepping motor; At least also have an electric motor driven yarn feeding part on support, this part can fricton-tightly be supplied with yarn by its circumference, and this part has independently yarn guiding and detection agency simultaneously.
In this device,, can help reducing the size of knitting machine circumferencial direction greatly if two yarn feeding parts relatively are installed in the both sides of support.The structure of a kind of embodiment that should preferentially adopt is, two yarn feeding parts that driven by same stepping motor are co-axially mounted on the axle of stepping motor, and have at least a yarn feeding part to link together by a clutch and the motor reel that can select to move.Above-mentioned clutch can be used electrical control, so just can handle according to program by a center command generator.
Certainly, this yarn feeding device also can be designed to following structure in principle: be contained in each or several thread wheels on the same yarn feeding part on the motor reel, drive by the stepping motor that is fixed on separately on the support.This structure has less relatively size.
The characteristics of this novel yarn feeding device are, simple in structure, volume is little, and this is because have only support and securing member thereof need take place on the circular knitting machine circumference, so that for being fed to few two one threads.Therefore being installed in a yarn feeding part on the support can drive or driven simultaneously, uses with what a kind of yarn feeding device can be finished many yarns conveying function of a weaving system (sinker type) and so-called reed eye machine (Ringelapparat) and send the yarn function.
The favourable structure of other of this novel yarn feeding device sees that dependent claims is described.

At Fig. 1 and the yarn feeding device shown in Fig. 2 is two kinds of only slightly different embodiment on detailed structure.This device has a support 1, has one to be used for the fixed structure that is connected with frame on this support, and frame can be the load-carrying ring or the coil holder frame of weaving loom.In the embodiment shown in fig. 1, this fixed structure is the part 2 that is positioned at the rectangular shape of support 1 end, and two fixing holes 3 are arranged thereon.In the embodiment shown in Figure 2, what be used for fixing support 1 is the part 4 that is positioned at the bow plate shape of bracket end, has limit groove 5(on this part and sees Fig. 3), so just the limit groove on the support can be stuck in above the retainer ring 6, and fixing by a fishbolt 7.Contact the end of a thread 8 is arranged in limit groove 5, and when support 1 was clamped on the retainer ring 6, these contact the end of a thread just can contact with cable 9 in known manner.
Fixing motor 10 on support 1, this motor can be self-drive synchronous motor, also can be stepping motor.In the end of stepping motor 10 fixed flange 11 is arranged, trip bolt 12 closely connects together the corresponding surface of this ring flange and frame 1.As depicted in figs. 1 and 2, in this structure, motor reel 13 is horizontal on the support that assembling finishes substantially.
At motor reel 13 radially, fixing two yarn feeding parts; This part is two jar shapes, and by the yarn feeding dish 14 that plastics or light metal are made, the surface 15 of these two yarn feeding dishes and support 1 is isolated from the outside stepping motor 10 jointly and comes.The diameter of each yarn feeding dish 14 is all relatively greater than the diameter of the yarn feeding tube of known active type or memory type yarn feeding device.Have the air vent 16,17 of shape of slit on the yarn feeding dish, wherein air vent 16 is opened on the end face of yarn feeding dish 14, and air vent 17 is opened on periphery, and fin in addition ventilates in the inside of yarn feeding dish 14.Can produce cooling blast shown in 20 by said structure, this air-flow passes the inner chamber of yarn feeding dish 14, can cool off stepping motor 10.In order to prevent to fly yarn and foreign material enter yarn feeding dish 14 inner chambers, on air vent 16, be covered with dustproof filter screen 21.Because air vent 17 also might stop up, so yarn feeding dish 14 is made smooth surface.In can also the zone that is covered by jar shape yarn feeding dish 14 on support 1, an air vent 170 be set at least, and this hole and compressed air customer be connected together with a vent hose.
The circumference area 22 of each yarn feeding dish 14 all is cylindricality, 23 of its root area are tapered, the whole shape of yarn feeding dish 14 is as a funnel like this, long and narrow air vent 17 is distributing above the circumference area 22 of cylindricality, form parting bead 24 between each air vent, the reel for yarn that yarn constituted 26 to be fed just is wrapped in (see figure 1) above the parting bead 24.Because the diameter of yarn feeding dish 14 is relatively big, so reel for yarn 26 can correspondingly keep the less number of turns, the yarn feeding dish 14 during the selection of its concrete number of turns should be able to guarantee to rotate fricton-tightly supplies yarn feeding line 25 or 25a.
On support 1, each yarn feeding dish 14 all is equipped with yarn guiding and detection agency.In the embodiment shown in fig. 1, this mechanism by three become certain spacing arrangement advance yarn circle ring 27,28,29(or 27a, 28a, 29a) and two yarn circle rings 30,31(or 30a, 31a) and two lever jacks 32,33(or 32a, 33a) composition.Advance yarn circle ring 27 to 29(or 27a to 29a) be installed on the cambered plate 34 coaxial line, 34 of cambered plates are fixed on the support 1.Three axis that advance yarn circle ring are vertical with motor reel 13 basically.Equally, two yarn circle rings 30,31 also are installed on the cambered plate 35.The yarn of discharging later 25 at yarn circle ring 31,25a is at a flexible lever jack 330(or 330a) the end, pass a circle ring 310(or 310a), lever jack 330(or 330a) also be fixed on above the support 1, and can swing, its function also will be mentioned hereinafter.Circle ring 311 is fixed circle rings that are positioned at circle ring 310 back.
Each yarn feeding dish 14 all can have two or guiding of more above-mentioned yarn and detection agency, so that the yarn of many dispersions successively is wrapped on the yarn feeding dish 14, thereby stores and carries.This embodiment is highly beneficial for the product of producing no technical decorative pattern.Compare with embodiment shown in Figure 1, this structure only needs half or yarn feeding dish still less just enough.
On support 1, cover a transparent colored lid 37, adorning an operation disruption indicator lamp below the lid.All electric devices all link to each other with the end of a thread 8 that contacts shown in Figure 3, and are communicated with supply line by this end of a thread again.
Advance yarn circle ring 27,28(or 27a, 28a at two on the cambered plate 34) between Yarn Brake 39 or 39a also are housed, with they measure the input yarn rate of tension so that reel for yarn 26 is adjusted to a suitable degree.
By advancing the yarn 25 or the 25a of 27 to 29 inputs of yarn circle ring, the frusta-conical surface 23(that is introduced to separately sees Fig. 2), the reel for yarn that constantly forms is pushed the reel for yarn of front to cylindrical surface 22 automatically subsequently, and yarn 25,25a pass yarn circle ring 30,31(or 30a, 31a from cylindrical surface 22 then) drawn with the speed same with advancing yarn.The axle 13 of stepping motor is horizontal basically; Yarn then is in plumbness as shown in the figure basically.
Fig. 3 and embodiment shown in Figure 4 be similar with Fig. 2 basically, so identical part all uses identical index sequence number.
The stepping motor 10 of supporting yarn feeding dish 14 has the microscler ring flange 11a that visits yarn feeding dish 14 outsides, and this ring flange is installed on support 1 in the swing axle journal 40 on yarn feeding dish 14 next doors, and the axis of axle journal 40 and motor axis 13 parallel.Can make yarn feeding dish 14 swing to position shown in Figure 4 with stepping motor 10 from position shown in Figure 3 by this structure, its hunting range is determined by spacer pin 42.
On the swing axle journal 40, have unillustrated elongated slot among the figure, by this elongated slot dull and stereotyped 11a is stuck between Fig. 3 and two positions shown in Figure 4, and can swings flexibly.
In the multiple-pin type circular knitting machine, be closely aligned yarn feeding device above the load-carrying ring 6, cause the operation of yarn feeding device to be hindered, as the operation etc. of threading a needle of yarn.Fig. 3 and swing type yarn feeding dish 14 shown in Figure 4 then permission move on to the approaching position that is easy to shown in Figure 4 with yarn feeding dish 14 where necessary, can also relay then and get back on the operating position shown in Figure 3.
Above-mentioned swing type is installed also has other selection scheme, for example make yarn feeding dish 14 along support 1 vertically move or flexible, or otherwise adjust.
The ring flange 11a that can swing can monitor by an electric switch that is fixed on the support 1 on its position of showing, and the action element of this switch is made of spacer pin 42, so just can prevent to open unintentionally machine.In addition, when ring flange 11a is in when showing the position, the malfunction indicator lamp below the lid 37 is also glittering.
In the present embodiment, a pinching screw 44 and two movable branching rods 45,46 are installed above the ring flange 11a of prolongation, there is the guiding device of yarn 25 or 25a the end of pole 45,46, and its shape for example can be the spool shape.In order on two direction of rotation of yarn feeding dish 14, to work, the movable axis of pole 45,46 be made adjustablely, enter the yarn feeding dish and alleviate the work of threading by hand from the tangent line direction to guarantee yarn.
Among the embodiment shown in the figure, this feed carrier constitutes by being full of compressed-air actuated injector 47,48, and wherein injector 47 plays a part Yarn Brake on the direction of arrow 49 indications; Injector 48 then plays a part on the direction of arrow 50 indications for the yarn feeding line.The mode that compressed air is transported to injector is seen shown in Figure 3, and compressed air both can pass through flexible pipe 47a, 48a, and the air circulating line that does not draw from a figure is introduced, and also can obtain by the cooling air that compiles from air vent 170; Compressed-air hose 47a, 48a are directed into (see figure 2) in the injector 47,48 then.
Passing the yarn of injector 47,48, is to be conducted through under contactless state basically, is braked or is supplied to feed.Flying foreign material such as yarn can automatically be blown off from yarn.Also can blow on this yarn feeding device other above part, from the cooling air of air vent 17 on the yarn feeding dish 14 to prevent to fly the deposition of yarn and dust.
The structure of embodiment shown in Fig. 5 is as follows: 10(sees Fig. 2 at stepping motor) axle 13 two ends respectively have a yarn feeding dish 14 to be positioned at the both sides of support 1, the structure of yarn feeding dish 14 and shown in Figure 2 basic identical.So same part is all titled with same index sequence number.Each yarn feeding dish 14 all has independently yarn guiding and detection agency, wherein only drawn be fixed on cambered plate 34 or 34a and 35 or 35a on advance yarn and yarn circle ring 29,29a or 30,30a.
In the present embodiment, have at least in two yarn feeding dishes 14 one with total stepping motor 10, but disengaging type connect together so that when breaking down-winding yarn-unlikely another yarn feeding dish 14 that influences by hand for example.Electromagnetic clutch 100 among the figure can be by the signal of telecommunication control from slip ring 101 inputs.
Express among the next embodiment at another figure of no use, each yarn feeding dish 14 all has stepping motor 10 separately, and its connection also can not used clutch.The advantage of this structure is, under shared same support 1 and the shared same condition that is positioned at the indicator lamp below the lid 37, can obtain a kind of narrow structure.
In control circuit shown in Figure 6, electrical network is connected on the main transmission machine, for example receives on the circular knitting machine.Power passes to gearbox 61 by a gear-box, and the output revolutions of this gearbox can stepless change.Gearbox 61 drives an increment type transmitter 62 again, contains the detection wheel that a rotating speed with main transmission 60 has fixed speed ratio in this generator, can carry out photo-electric type or electromagnetic type scanning to this detection wheel.Increment transmitter by power unit 63 feeds sends the impulse wave 64 with different spacing frequency at its output, and this impulse wave is introduced into same calculator 65 by power unit 63 feeds then.The step-by-step impulse control signal of being sent by the output of calculator 65 66 is sent to the input stage 67 of each yarn feeding device again, and by final amplifier 68 control step motor 10.Input stage 67 and final amplifier 68 preferably are installed on the printed substrate 69, and then this printed substrate are fixed on the shell 36 of each yarn feeding device.
In input stage 67 and/or final amplifier 68 electric switch 70 can be set, can the power supply of stepping motor 10 be cut off respectively or concentrate and cut off with hand by this switch, perhaps by means of lever jack 32,33(sees Fig. 1) parking of control machine.The shutdown function of above-mentioned single yarn feeding device also can be arranged on the calculator level 65 as required, and still this practice is only broken in yarn feeding device and thread-carrier at yarn, and is just meaningful when causing fabric portions ground or having broken away from knitting needle fully.Under this situation, can in the yarn feeding device that has cut off power supply, again yarn be received on the knitting needle as required, and corresponding yarn feeding dish 14 can still continue idle running, but not change the size of reel for yarn 26.
On all use the yarn feeding device of the circular knitting machine of effect pin separately, can connect above-mentioned calculator level 65, adopt this grade can guarantee on circuit that the absolute synchronization of all yarn feeding dishes 14 turns round.By gearbox 61 is adjusted accordingly in addition the peripheral speed of all yarn feeding dishes and the yarn feeding amount of yarn feeding device are changed simultaneously with same numerical value.Because stepping motor is the stepping amount of executable unit's machine revolution accurately all, so can guarantee of the speed operation of all controlled yarn feeding devices with absolute unanimity.Even at starting/stop phase, the stepping motor of machine also can keep synchronous operation.
When main transmission 60 sudden power of machine, yarn feeding dish 14 is not braked in the process that is rotated further at machine and continues synchronously yarn to be delivered to each from knitting needle and knit a little, at this moment because the effect of the coercive force of each stepping motor interior permanent magnet system, produce the Yarn braking of action voluntarily, thereby got rid of each yarn feeding device broken string of being worried and be sent to each and knitted a little the too much or very few situation of line.For above-mentioned reasons, when stopped status, it is motionless that the position stability ground of stepping motor 10 rotors keeps; But operation can be rotated on two direction of rotation with hand in order to try to make a match etc.However, this yarn feeding device can prevent the loose or coil snarling of yarn in normal operation, can also avoid adjusting a large amount of phenomenons that reduce of yarn feeding amount that knitting system produces on the other hand and take place, because the moment of torsion of stepping motor 10 will be strengthened to and be enough to resist yarn it is drawn the degree of wearing because of mistake.
This yarn feeding device can not only resemble works in the mode of positive operation shown in Figure 1, the yarn of introducing from the tangential direction of yarn feeding dish 14 25 at this moment, and the speed of 25a forcibly equals the speed of drawing of yarn; This device also can be worked under the mode of operation of non-homogeneous yarn consumption (so-called passive type) in case of necessity, at this moment goes out coil loop 30, and 30a(sees Fig. 5) layout should be able to make yarn 25,25a crosses the head of the yarn feeding dish 14 that is the yarn feeding barrel shape and draws.In this case, should suitably select to determine the voltage of the step frequency of stepping motor 10, make that yarn feeding device at least can be for feeding maximum yarn demand.If the yarn demand reduces, then the reel for yarns above the yarn feeding dish 14 26 increase, and send signal command stepping motor 10 up to detecting element and stop or stepping motor 10 is switched on the lower revolution.
Under specific situation, this yarn feeding device can also be used as the friction-type yarn feeder.At this moment the voltage of step frequency that should decision stepping motor 10 is selected enough highly, makes yarn feeding device as if supplied with the yarn of knitting system " excessive ", and at this moment all knitting needles all must come into operation.But have only a few loop yarn lines seldom on the reel for yarn 26, what therefore realized is not fricton-tight yarn feeding, but the portable type yarn feeding of yarn under the frictional force effect, its yarn feeding amount is relevant with the tension force of each one thread.
The yarn feeding device that control circuit is controlled in the schematic diagram of being represented by Fig. 6 also can be applied in the use of producing the annular distance fabric and act on separately on the circular knitting machine of pin.This circular knitting machine has self-figure limit device, or a kind of jacquard weave formula (Jacquard) knitting machine.In this case, will contain a decorative pattern generation circuit 71 in the control circuit, this circuit is received signal from the decorative pattern memory 72 on the machine, sends the control instruction of decorative pattern by cable 73.Decorative pattern memory 72 on the machine can resemble and make decorative pattern wheel or decorative pattern tube, forms such as punched card reader or memory under program known.The control instruction of decorative pattern is admitted to program counter 74, carried out necessary signal conversion later on by the cable output control instruction and the decorative pattern information of calculator level 65 in this calculator, this control instruction and decorative pattern information and step-by-step impulse 64 constitute the control signals 66 of each stepping motors jointly.
In so-called annular distance operation, when promptly producing the annular distance pattern fabric, so-called one-tenth ring device to be installed, on circular knitting machine so that weave desirable decorative pattern.Can the requirement according to decorative pattern start or stop yarn feeding device in aforesaid operations by the decorative pattern control circuit, also start or stop the Yarn guide mechanism that is fitted together simultaneously, Yarn guide mechanism respectively has quadruplet on the one-tenth ring device in each knitting system usually.So the yarn feeding device of quadruplet the above-mentioned type should be arranged on each knits a little, wherein always have a manipulation that is enclosed within decorative pattern memory 72 to work down.Under this duty, the stepping degree of accuracy of stepping motor 10 has great significance, because yarn feeding device is wanted and can very accurately be started and stop.This requirement can be met by following measure, makes program counter 74 contain the respective value that a cover is formed by the counting unit that can freely program, and this cover numerical value is handled by decorative pattern memory 72.
Counting unit also can allow two cover yarn feeding devices in the knitting needle co-operate of so-called exchange point (position that yarn is introduced and drawn during colour switching) by some, when from a kind of color transition to another color, can obtain flawless junction like this.
In the embodiment shown in fig. 1, each is responsible for driving a yarn feeding dish 14 to be equipped with two stepping motor 10(on the yarn feeding device), yarn 25 or 25a from yarn circle hole pass the circle hole 310 that is positioned on lever jack 330 or the 330a termination, 310a, and pass retainer plate hole 311 or the 311a that is fixed on the thread-carrier support.As mentioned above, flexible lever jack 330,330a are respectively connecting a switch 37 that is installed on the casing, and according to the diverse location of lever jack 330 or 330a, this switch can start or stop stepping motor, and what represent with solid line in Fig. 1 is the operating position; What dot is stop position.On the 3rd position, promptly when broken string took place, entire machine was stopped.
Use on the knitting garden machine that acts on pin separately at one, its Purely mechanical annular distance device control function is as follows:
In the moment of certain knitting system turn colors, a new annular distance thread-carrier is put on its yarn.At this moment will produce pulling force on yarn, this pulling force is that the threaded run by the annular distance thread-carrier is produced.At this moment lever jack 330 or 330a enter the operating position shown in the solid line among Fig. 1 with circle ring 310 and 310a, and stepping motor 10 is in on-state on this position.The annular distance thread-carrier that this on-state is maintained to the annular distance device loosens its yarn again, when causing the pulling force disappearance on the yarn.At this moment, flexible conductor rod 330 or 330a be because the effect of elastic force turns back to initial position, and take yarn to place that dotted line draws, and at this moment stepping motor 10 stops operating.
Yarn feeler 33 or 33a can have three kinds of different position of the switch, that is:
Position 1: stepping motor 10(or clutch 100) " leading to " do not stop entire machine,
Position 2: stepping motor 10(or clutch 100) " breaking " do not stop entire machine,
Position 3: stepping motor 10(or clutch 100) " breaking " stops entire machine.
In so-called selvedge operation, when promptly weaving lace, the fabric body is different with the needed yarn in fabric headdress flower limit.Because the stepping motor of yarn feeding device can be controlled respectively,, make the needs that adapt to various knit patterns for the amount of thread of feeding so can send control instruction according to the decorative pattern in the decorative pattern memory 72.
If being what is called, knitting lace has the additional decorative pattern that serves as a contrast yarn, and the pin thing does not need to inweave additional lining yarn on one's body, then should introduce by the active yarn-feed dish on the yarn feeding device 14 adding the lining yarn, the stepping motor 10 of this device or clutch 100 are connected or are turn-offed according to decorative pattern, and not needing has increased complex apparatus in addition again.
When braiding jacquard weave kind fabric, need this novel yarn feeding device to adopt the working method of active yarn-feed equally.Knitting needle on the decorative pattern information of storing in the decorative pattern memory 72 and each are knitted is a little selected in full accord.As mentioned above, program counter 74 and calculator level 65 calculate each stepping motor 10 and clutch 100 needed step frequencies thereof according to pattern structure, and supply to feed needed amount of thread with very high accuracy active type ground.
Suppose that every knitting needle will weave a mesh according to the decorative pattern shape, the yarn " X " that needs some, the amount of thread of the needs of the every knitting needle that need not weave is that " Y " (this part line is to constitute yarn to connect necessary ((float needle)), it is used to weave the next line mesh), then to distribute yarn definitely equably in positive mode.Even also can accomplish this point on the transition region of fringing decorative pattern or lace, knitting needle is selected because yarn feeding is simulation.Every needed amount of thread of knitting needle " Y " that does not drop into braiding is irrelevant and be constant with the intensity of product, because the sinker mesh between each knitting needle mesh all has identical length with the sliding pin of so-called yarn.Consequently only need change the yarn feeding amount of those braiding knitting needles during mass change, this can compile by program counter 74, and with 65 realizations of calculator level, both send corresponding step-by-step impulse jointly, should be for the amount of thread of feeding with 10 of stepping motors controlling each yarn feeding device.
In order to change the quality of fabric, only need adjust gearbox 61 and get final product in shutdown or in running status.
In addition, this yarn feeding device also can be used in loom, warp knitting machine, and the parallel on the machines such as Raschel looms is for feeding in the mechanism.At this moment can adopt the active type parallel for feeding, make the parallel of walking send the speed of latitude mechanism (for example wire loop on the wire loop loom) under the manipulation of control circuit, to make the unlikely peak tension that occurs on the parallel according to it by yarn feeding dish 14.
Above-mentioned all embodiment of this yarn feeding device not only can be directly installed on the various machines need yarn point near, also can be installed on the bobbin volume framework on machine next door.Because the stepping motor of each yarn feeding device can both independently be controlled, and stepping motor 10 itself can guarantee the yarn feeding dish 14 absolute synchronization rotation of all yarn feeding devices, so can connect together with concentrating detector and the control circuit settled by a control cable simply, detector and control circuit for example can be installed on the machine of finished yarn.When adopting knitting garden machine, equally long for the path of accomplishing yarn, bobbin can be rolled up framework and make annular, make it round the garden machine.
