Description
With reference to the related application that is transferred present assignee by the inventor, content disclosed herein is to combine U. S. application №, requires German application P34 29 193.8.Lawyer's document 85465, PA45.
The invention relates to textile machine, or rather, is about the device of giving textile machinery yarn supplies such as knitting machine, loom.The present invention be particularly suitable for being applied in need knitting machine with predetermined tension force feeding yarn on.
From the 3rd, 858, No. 416 US Patent can be recognized a kind of Yarn supply device, comprises a cylinder that is contained on the drive motor axle for the yarn element on this device, be about to the yarn confessed on the circumferential surface of cylinder around several circles, fricton-tight to guarantee for yarn.A motor is used as the drive motor of cylinder, and its speed can be regulated by the method that changes power line voltage on a kind of concrete device, and the method for pulse that then can be by control feed-in motor on the concrete device of another kind is regulated.By the velocity variations of motor, make for the speed of yarn cylinder synchronous with the speed maintenance of the knitting machine of being furnished with this Yarn supply device.For it, a pulse converter links to each other with the rotor of circular knitter, and send a kind of pulse output signals of representing the circular knit motor speed, this output signal is converted to an aanalogvoltage by a frequency, this aanalogvoltage sends with a speed measuring motor that is connected with drive motor or increment conv, and the output signal that has been converted to correspondent voltage is compared.By a regulating control, when the control skew occurring, the speed of confession yarn cylinder just is adjusted to the pulse converter predetermined target value by circular knitter.
For the tension force that will feed the yarn on the pin remains on the predetermined value, in this Yarn supply device, supply the downstream part of yarn cylinder to be provided with a tension sensing device in working direction, i.e. probe along yarn.Signal of sensor connects the signal that the source takes place same expected value can be by selectively by the switch activated regulating control that is input to, and by controlling and driving motor correspondingly, regulating control is just determined yarn tension according to predetermined target value.
In having the circular knitter of needle-thread tensioning control device, the Yarn supply device that links to each other with cam system sometimes must be by a certain pattern for yarn in the process of knitting machine one commentaries on classics or several commentaries on classics, sometimes cut-off yarn in temporary transient suddenly this means the influence of the variation of the mode of operation that supplies the yarn situation must be subjected to a specific needle-thread tensioning control device simultaneously.Generally also by certain pattern work, the demand of yarn also is different to jacquard knitting machine in each cam system, is constantly changing.For yarn feeding, must correspondingly use so-called storage feeder, yarn is drawn bobbin bank or overhead from bobbin when needing, and still, has used after these yarn feeders, just yarn feeding energetically.
For all these application scenarios, the yarn amount fluctuation that its each cam system unit time extracts out is very big, therefore, must keep synchronous Yarn supply device to be unsuitable for being used in this occasion with an outer impulse source pulse converter of the cylinder rigid joint of circular knitter (for example with).
A target of the present invention will be created a kind of Yarn supply device exactly, can be with this Yarn supply device according to specific yarn-using amount requirement with yarn feeding device, supply yarn independently and energetically with predetermined tension force, and do not need with an external clock pulse be that sync souce keeps synchronously.In this device, even when zero yarn amount, just when the extraction of yarn was interrupted, the tension force of yarn still can be kept.This is a particular importance in as needle-thread tensioning control device above-mentioned.And this Yarn supply device simplicity of design is given prominence to its numerous possible application.
Briefly, the speed of drive motor with represent the signal of sensor of yarn feed speed synchronous, sensor (promptly pop one's head in) is contained in the place of seeing the supply roll back certain distance of yarn towards the yarn working direction.
If at the output place yarn of Yarn supply device motion (when the need yarn time) is arranged, probe will determine whether yarn advances by predetermined yarn speed.Probe sends the output signal of representing yarn speed, is synchronous because supply the drive motor of yarn element with this output signal, is moving under corresponding superficial velocity so drive motor drives for the yarn element, like this, just can press required amount of thread for yarn.
Occasion at elastomeric yarn, when the motion change of yarn, the length of the yarn that occurs later along the working direction feed element of yarn changes and can be absorbed by the elasticity of yarn itself, if this absorption is talked about not enough fully, it is suitable then on the yarn advance route that supplies between yarn element and the sensor thread reserve being set, this deposit is by obtaining as this way of U-shaped yarn circle, and on the route of U-shaped yarn circle, yarn is guided by corresponding steering component.Deposit for fear of yarn when the requirement of yarn changes becomes excessive big or excessively little, and Yarn supply device preferably has an energy size of yarn deposit is maintained regulating control on the designated value.
In described concrete device, Yarn supply device can with zero tension force or certain force of strain to yarn feeding device for yarn.Because along with the performance of the final yarn of the product that will produce and the difference of other factors, the tension force of yarn usually also is different, so in a kind of concrete device of preferential employing, be provided with control by the controlled tension device of feeding the tension force of the yarn that for the yarn element, this device is located at on the yarn road between yarn element and the probe.These tensioners preferably have an energy automatically yarn tension to be remained on regulating control on the predetermined designated value in needs.
Use stepping motor for the drive motor of yarn element is suitable, the output signal of sensing device or probe is fed into this motor, and if required, this signal can be converted into corresponding step-by-step impulse sequence and be exaggerated.In addition, Yarn supply device also can have a servo-operated regulator, and it is according to the speed of constantly adjusting drive motor (definitely, this drive motor is a stepping motor) as the signal of sensor of instruction.
The speed of advance of yarn can be measured with any suitable method, and this way should be able to obtain as far as possible accurately to represent the output signal of the speed of advance of yarn.If probe is to use with the fricton-tight cooperation of yarn and be connected the low inertia measuring pulley of a signal converter, then require the condition that reaches very simple.This signal converter can be an electrical generator, its output and the proportional voltage of measuring pulley speed, and perhaps, it can also be the digital reader of an angle, its direct instrumentation measuring pulley, such as, use method of optics.
Has such tension element in the above-mentioned tensioner that is used for being created in the yarn tension that specified time needs, this tension element can move between two yarn count support points, the working direction of yarn laterally acts on the yarn relatively, and load an adjustable power, this adjustable power can be gravity, spring force or electromagnetic force.
This Yarn supply device preferably also has one and connects sensor output signal, and the telltale of yarn feeding amount in the unit of display time, this telltale also can add the telltale for yarn tension that demonstration is recorded by yarn tension measuring device is set.Use this way, just can in needs, read the yarn feeding amount of each cam system of circular knitter, and it is adjusted to designated value, and do not need specialized equipment for this purposes.
On the other hand, or additionally, Yarn supply device also can have a signal line connecting, can inquire the output signal of probe and/or the signal of expression hello yarn tension by this channel.By this connecting device, each Yarn supply device, such as each Yarn supply device with circular knitter of a plurality of cam systems also can be connected to a central display, also can selectively an automonitor be linked to each other with this central display.Showed the deviation that surpasses permissible value if the yarn feeding of each cam system measures, this monitor unit is just carried correct amount to the drive motor that connects Yarn supply device, perhaps even make the entire machine parking.If each Yarn supply device is joined the unsuitable words of the expense of a private read out instrument, also can connect a manual read out instrument with certain interval, so that monitor yarn feeding amount and/or tension force with the connecting device on each Yarn supply device.
If the drive motor of Yarn supply device links to each other with a reserve motion switch, in fact resetting then of knitting machine became than being easier to when knitting machine need carry out start-up function or Yarn break when stopping.Because have a reserve motion switch just can be before resetting knitting machine with excessive extraction and the yarn that flexibly hanging is recoiled and is gone back have prescribed tension so that guarantee the yarn of each cam system at once.
In a good concrete device; tension probe can link to each other with drive motor; like this; if being reduced to a predetermined threshold values and yarn feeding under the tension force of yarn ends; when just knitting machine is shut down; this tension probe will be exported a signal and make drive motor counter-rotating, and reverse drive unrolls yarn for the yarn element, till reaching predetermined yarn tension value.After yarn breakage or yarn were tied together again, the yarn tension that needs also can automatically rebulid in this way.Move to an ad-hoc location on the spy arm expert trend of the closing appliance that inputs or outputs, can unroll like this.
Such just as has been noted, the fancy yarn Yarn supply device is independently, does not need the system of external sync accessory equipment.Configuration aspects, if all be contained on the same bearing for the electric switch element of yarn element (being in this Yarn supply device) with sensing device and controlling and driving motor for yarn cylinder or circle drum, then whole device becomes a compact structure, and it can method routinely be contained in the suitable place with the machine of yarn.
This Yarn supply device can not only be used to have the circular knitter of needle-thread tensioning control device, jacquard knitting machine etc., in general, also can be used in any with on the textile machinery of yarn, if on this machine with predetermined yarn tension continuously or intermittently, or with the yarn feeding amount that changes to being important words with the yarn feeding device yarn feeding.This Yarn supply device is particularly suitable for knitting hosiery machine, also the Yarn supply device of not finding to have the requirement that can satisfy these machines till now.Especially be used for knitting in the seamless hosiery machine of the senior hosiery of women, the circle length of long part can correspondingly continuously change by the method that raises or the reduction needle stand changes the consumption yarn amount of machine revolution continuously on the leg.The fancy yarn Yarn supply device can automatically be regulated according to these requirements, and does not need special control command or machine circuit.
And, in general in this Yarn supply device, be positive for yarn, also because its simplicity of design, do not have complicated part in addition and unusual, and can be contained between the bobbin of circular knitter and the thread-carrier Anywhere.Its easy operating all can be worked in any position, does not need maintaining.When the performance of machine and kind changed, Yarn supply device need not done any change.Originally installation of Xu Yaoing and adjusting work all can save, and routinely, this work is very time taking, and can only be finished by skilled workman.
Fig. 1 is corresponding Yarn supply device scheme drawing of the present invention and relevant circuit block diagram.
Fig. 2 is the lateral plan of the actual concrete device of Yarn supply device of Fig. 1.
The Yarn supply device of representing among the figure has a casing 1, and it can be installed in on the textile machinery of yarn, for example is loaded on the frame of circular weaving machine with U-shaped framework 2 among the figure and clamp screws 3.The yarn tube 4 of confession yarn element is contained on the casing 1 and with stepping motor 6 and directly is connected.
For controlling the yarn feed speed of feeding to yarn, be installed in the same side of casing in the mode that parallels with axis for yarn tube 4 as detector or probe, and link to each other with the speed measuring motor 9 that is loaded on casing 1 by axle 8, also available angle sign indicating number reader or other pulse transducer replace speed measuring motor 9.
Leave the yarn 11 of measuring wheel 7 and drawn by two coaxial output guide eyelits 16, two guide eyelits 16 are fixed on the casing 17 by carriage 17.Monitored by the spy arm 18 that is installed in the output closing appliance in the casing at the two output yarns 11 of leading between the yarn outlet hole 16.Visit that arm 18 is fixed on that 19 of casing 1 go up and rotatable.Be sent to such as yarn feeding device such as the cam system of circular weaving machine by the yarn that comes out of output guide eyelit 16.
The input of yarn 11 is monitored by an input closing appliance that is contained in the casing 1.It is visited arm 21 and is supported and can be rotated around it by fulcrum 20.Visit arm 21 and monitor yarn 11 motions in the downstream (along the yarn movement direction) of second output guide eyelit 13.In the zone between yarn feeding tube 4 and measuring wheel 7, yarn 11 is advanced via tension roller 22, and this roller is loaded on the bar 23, bar 23 be loaded on casing 1 point 24 places and can be around this spot wobble.Bar 23 joins at 24 and second bar 25 of point.The control position approximate horizontal of bar 25 also is equipped with a pouring weight 26 thereon.Pouring weight 26 can move at its axis of bar 25 upper edges.
Can regulate the position of pouring weight 26 on bar 25 at any time according to scale 27.
As shown in Figure 2, under normal operation, the mounting means of tension roller is to make to be positioned at the yarn feeding tube 4 surface straight line that links to the yarn 11 on measuring wheel 7 surfaces and two surfaces certain departing from arranged.Can make yarn have certain deposit by means of this departing from.According to shown in Figure 2, when axle 24 rotates along clockwise direction, just can utilize this deposit when bar 23,25.
The speed measuring motor 9 that links to each other with measuring wheel 7 among Fig. 1 is connected with distributor circuit 33 with data preparation.They are by lead 30, and its function of switch 31(will be given explanation in the back) be connected with lead 32.This speed measuring motor is represented the signal of yarn movement speed to data preparation and distributor circuit 33 outputs with the form of aanalogvoltage.
Electric voltage/frequency converter 35 warps 34 link to each other with distributor circuit 33 with data preparation.Conv 35 converts the analog signal (this signal may be exaggerated) of speed measuring motor 9 outputs to spike train in data handing and distributor circuit 33, its impulse rate is represented yarn speed.Pulse output signals 36 warps 37 input control circuits 38, the mouth of control circuit 38 are then joined by line 39 and stepping motor 6.
Telltale 41 warps 40 link to each other with electric voltage/frequency converter 35.Speed measuring motor represents that the pulse output signals of yarn gait of march then demonstrates the data of yarn movement speed at any time on this telltale.This telltale is positioned at a side (see figure 2) of casing 1.
Be output speed measuring motor pulse output signals, electric voltage/frequency converter 35 is furnished with external signal line, and available socket 42 connects, and whereby, also can measure this signal beyond yarn feeding device.To elaborate to this below.
The brush 50 of the potential device of representing among Fig. 1 49 is connected with the revolution axle 24 of bar 23,25.This potential device sends the signal of indication rod 23,25 angle positions (being the position of tension roller 22).This signal imports regulating control 52 into by circuit 51.Regulating control 52 contains an expected value transmitter; And this transmitter is joined by circuit 53 and control circuit 38.
It is line 55 among the figure that electric current is transported to separately circuit part supply line by electric supply installation 54, and leading to separately, the circuit of circuit part then is 56-58.
The electric current that provides to data preparation and distributor circuit 33 is through line 59 and switch 60 inputs.This switch 60 mechanically joins with tension roller 22.Two opposite polarity supply line 61,62 link to each other with switch 60, so data preparation and distributor circuit 33 can be judged switch 60 residing positions according to the polarity of circuit 59.
The function of described Yarn supply device is as follows:
It is zero that initial imagination needs the need for equipment amount with yarn.The yarn feeding device present position as shown in Figure 2.At this moment, yarn has its tension value of certain tension force by the determining positions of pouring weight 26 at bar 25.
Then supplied with by Yarn supply device when the device that uses yarn need be used yarn, as when the needle-thread tensioning control device of circular weaving machine is imported yarn, yarn is then via 16 inputs of output thread eye.Thereby 7 of measuring wheels inhour rotates (see figure 2)s, then reduced promptly by the yarn of tension roller deposit and partly used up.
In case measuring wheel 7 begins to rotate, 9 of speed measuring motors send output signal (being directly proportional with yarn movement speed) via line 30 and pass to electric voltage/frequency converter 35 by data preparation and distributor circuit 33 again.Be converted into the stepping pulse signal with corresponding step frequency at this analog output signal, its signal value also is directly proportional with yarn movement speed.This pulse output signals 36 passes to stepping motor 6 through control circuit 38 and circuit 39 then, and this motor-driven yarn feeding tube 4 rotates, and its circumferential velocity is consistent with yarn movement speed.The pulse of passing to stepping motor 6 by control circuit 38 can be represented the full-shape increment or the segment angle increment of stepping motor.
Meanwhile, computing machine 44 is by the data of line 43 receptions about yarn movement speed.These data or be stored in the computing machine or be used to produce output signal and as shown in Figure 1 via circuit 45,47 and its position of switch 48() and deliver to telltale and be revealed.
Do not consider now yarn is how to import the yarn operative installations in order.Stepping motor 6 drives the speed of yarn feeding tube 4 and the yarn feeding amount size was relevant at that time, and its size is by measuring wheel 7 decisions.Pass through the effect of speed measuring motor 9 stepping motors 6 and the circuit between them 33,35,38 like this, measuring wheel 7 and stepping motor 6 strict synchronism.
The tension force that is delivered to yarn feeding device by yarn is determined by the position of pouring weight 26 on second bar 25.In case yarn uses when stopping, the speed of measuring wheel 7 also decreases, and then the speed of stepping motor 6 is descended.So the speed of yarn feeding tube 4 also just reduces up to yarn feeding device and stops fully for line.Even yarn also kept its predetermined tension value when machine stopped, this effect is to be finished by the tension roller that works between yarn feeding tube 4 and measuring wheel 7.
When for the yarn velocity variations, the yarn storage content that is formed by tension roller 22 also changes thereupon.Its storage content of effect by potential device 49 and regulating control 52 can keep certain.Therefore potential device 49 can learn that by the signal that line 51 sends expression tension roller 22 positions at any time yarn feeding tube 4 and measuring wheel 7 grip the storage content of yarn between the point.Above-mentioned signal is compared with an expected value in regulating control 52 and is sent signal according to its possible deviation.This signal imports control circuit 38 into via line 53 again, and circuit 38 then correspondingly changes its output signal via line 39 and passes to stepping motor 6 to be made it rotate a certain angle to compensate this deviation.Just can eliminate deviation through above-mentioned a series of adjustment.
The yarn tension value of determining can be by a probe 69 monitorings, and it delivers to data preparation and distributor circuit 33 via circuit 70 with corresponding monitor signal, by circuit 33 corresponding data is defeated by computing machine 44 again.When desiring to know yarn tension, its data can be shown on telltale 41 through switch 48 by output line 46.
If during machine switched off, the yarn tension of Yarn supply device is zero.For example because during yarn coil sagging (be its sagging be lower than predetermined lower bound), pouring weight 26 makes the yarn tension roller go to its end position and bar 23,25 is started and its switch that links to each other 60 around its fulcrum.Above-mentioned action can produce following effect.The pulse transducer that warp 102 sends the pulse of isopulse frequency is switched on by line 101.Data preparation and distributor circuit 33 provide the counter-rotating instruction of stepping motor 6 to control circuit 38 through electric voltage/frequency converter.After the impulse singla feed-in stepping motor 6 that pulse generator 100 sends, 6 of stepping motors are to the direction starting in contrast to yarn feeding.Begin sagging yarn is wound up up to making the yarn tension roller get back to its normal position again with 60 groups times its normal positions of switch for yarn tube 4 thus.This moment, the impulse singla transmitter quit work immediately.
If without pouring weight 26, also can adopt adjustable spring, electromagnetic force or other method application of load in yarn tension roller 22.Tension roller 22 also can directly be become one with probe 69, and promptly the yarn tension roller produces to open with doing to measure yarn tension simultaneously and uses.
In described concrete device, the output signal of speed measuring motor 9 is through suitable conversion and amplify back direct control stepping motor 6.In addition, the output signal of speed measuring motor 9 also can be used as expected value and keeps stepping motor 6 and speed measuring motor 9 synchronous.Constantly regulate the rotating speed of stepping motor 6 according to the servo-operated regulator in this expected value control circuit.
With yarn output, the input closing appliance of visiting arm 18 and 11 outputs of 21 monitoring yarns and input, when broken yarn, then can visit arm 18 and 21 fire switchs 31 by it respectively.The output signal of speed measuring motor 9 interrupts making stepping motor 6 stalls on the one hand, and stop signal is delivered to the engine installation of knitting machine via line 72 on the other hand.When output and (or) when input was visited arm 18 or 21 and is arranged in the position of the 18a of Fig. 2 or 21b separately, 21 on switch was communicated with two lines in left side among Fig. 1.When above-mentioned position, output or input are visited arm 18 or 21 and are added with certain spring force; So visit arm 18 or 21 and can only lean on conscious manual activation to regulate its position this moment.The effect of doing like this is that warp 73 makes stepping motor 6 counter-rotatings to electronic control circuit transmission signal.So, visit arm 18 or 21 and just can make stepping motor do of short duration counter-rotating thereby can establish the working tension of yarn again by regulating output or input when broken yarn with subsequently again during binder yarn.
At last, there has been junction block 42 just can export the signal of representing yarn tension or yarn movement speed to central exterior display device or central control apparatus.Central authorities' control apparatus can be when needed set up synchronized relation between each Yarn supply device (such as Yarn supply device of circular knitter) by the electronic control circuit 38 of each Yarn supply device.Control command equally also can be delivered to electric voltage/frequency converter by junction block 42, passes to electronic circuit 38 from that again.
Whole as shown in Figure 2 Yarn supply device is contained in the rectangular box 1 compactly, is equipped with in the main side of casing 1 for yarn tube 4, measuring wheel 7 and telltale 41.When yarn inputs or outputs closing appliance when working, or when other objectionable service conditions occurring, monitor lamp 730 will be bright.
