Description

Method and tricot machine for being prepared to tricot machine

Technical field

The present invention relates to a kind of for preparing tricot machine the method for (Einarbeiten) new flower-shaped (Muster), at this The yarn of warp thread is penetrated into sley point (Legenadel) and being total to by sley point and knitting needle (Wirknadel) in method Same-action forms at least one coil column (Maschenreihe).

In addition, having at least one main shaft, at least one yarn guiding chase comb the present invention relates to a kind of tricot machine (Legebarre), at least one knitting needle sley bar, yarn balancing device, at least one yarn feed drive device and at least one knit Object pulling device (Warenabzug).

Background technique

Usual necessary data use for can be also simply referred to as the known knitted fabric (Wirkware) of " flower pattern ".Especially Ground, band yarn movement (Legung) belong to the data for the magnitude of the yarn warp let-off and for the magnitude of fabric extraction.Therefore work as Because such as warp beam damages (abgearbeitet) or tricot machine completely and should be changing to another flower pattern and must carry out standard to tricot machine When standby, operator penetrates into yarn in sley point, one or more coil columns is generated, wherein in each stitch forming process It pulls yarn with tightening manually afterwards, yarn feed drive device is then started with the yarn warp let-off value of setting, machine can produce in column Other coil, until can utilize fabric traction device extraction generate knitted fabric, then start fabric traction device and It can start to produce.

However when that should generate new flower-shaped, it is not or not necessarily all necessary data is for using.In general, setting band yarn fortune It is dynamic, that is to say, that sley point is moved towards relative to the movement of knitting needle.However the yarn warp let-off for example must be measured rule of thumb.In this regard, Need the certain experience and corresponding feeling of operator.In each work step, correspondingly exists and pass through operation Risk caused by fault and shortage professional knowledge.As a result, at knitting element (Wirkelement) and/or also in process material It is damaged at material, such as yarn.Preparation is correspondingly time-consuming and high-cost.

Summary of the invention

Task of the invention lies in simplify the preparation carried out to tricot machine in new flower-shaped situation.

The task solves in the following manner in the method for the type that beginning refers to, that is, measures the tension of the yarn fed And the tension is limited in preset maximum value.

The limitation of yarn tension avoids excessively high yarn tension.Therefore braiding tool is reduced quite significantly The damage of (Wirkwerkzeug, sometimes referred to as circle forming) or thread material.In addition, the limitation of the tension of the yarn fed is permitted Limitation in terms of the parameter of Xu Ke unrestricted choice, so that operator can only also work in the working region of limitation.This into One step simplifies preparation because modification possibility and therefore same likelihood of failure can be kept into it is smaller.Of circular yarn Power preferably measures at the component for not guiding yarn directly herein.This is not related to the tension of single yarn equally, but is related to The tension present in the entirety of the yarn conveyed as beam of a loom.

Preferably, coil column is formed in the process (Kriechgang) that tricot machine is run with crawl speed.Therefore it is adopting With it is new flower-shaped when preparation during, can with low-down speed run tricot machine.The tension of yarn is actually independent of in warp The operating rate of volume machine.

Preferably, yarn is measured in the tension at following time point, i.e., sley point reaches it after knitting needle at the time point Rollback point.Here, carrying out the maximum deflection of sley point.At this point, the spacing of different knitting elements is maximum.Correspondingly Ground, the tension of same yarn is maximum herein.It is sufficient that, measures tension herein and the tension is made to become other processing mode Basis.

Preferably, tension is adjusted by adjusting yarn feed drive device.Yarn feed drive device initiatively drives warp beam, warp The yarn of yarn is extracted out from the warp beam.In production run (continuously generating knitted fabric in the production run) later, yarn Line feed drive device is run with constant yarn warp let-off value.Yarn warp let-off value is usually illustrated with " mm/R ", i.e. millimeter every lacquer. To tricot machine using it is new flower-shaped when preparation when one of task be, measure relevant yarn warp let-off value.It can be by following Mode measures yarn warp let-off value, i.e. setting tension and such moving yarn feed drive device in closed loop regulating loop, i.e., so that Also reach but be less than the tension.When yarn feed drive device exports excessive length of yarn for every stitch forming process When, tension is too low.When yarn feed drive device exports very few length of yarn for every stitch forming process, tension is excessively high.With Correspondingly, " conveying speed " can be adjusted to suitable yarn using relatively simple adjusting for yarn feed drive device In line warp let-off value.Here, yarn feed drive device in the stage of preparation continuously advance be not necessarily it is necessary.Yarn Feed drive device can also be run with relaying, i.e., convey some yarns in short time and then stop again.Therefore it should only avoid excessive Peak tension.In addition, can also there is low-down tension or complete in the yarn completely transiently during stitch forming process Tension is not present entirely.Yarn feed drive device is only run on positive driving direction in any situation, that is to say, that in this way Direction on, i.e., yarn feed drive device exports yarn in the direction.

Preferably, start fabric traction device and after starting fabric traction device yarn feed drive device metering needle pair Continue in the preset time.The change for obtaining the appearance of knitted fabric by starting fabric traction device.Do not knitting In the case that object is extracted out, each coil column is to a certain extent it may be said that " (auf Block) blockingly " is generated.The line of each coil column Enclose knitted fabric production mode reform actually against each other.It is then obtained by starting fabric traction device slightly different outer It sees.Depending on what speed to run fabric traction device with, more loose or more close knitted fabric structure is obtained.Yarn feed drive Then the adjusting of device also has an impact the structure of knitted fabric, because when yarn feed drive device is defeated for every stitch forming process It is comparable to realize more loose needle in the case where every stitch forming process smaller length of yarn when sending biggish length of yarn Fabric.After starting fabric traction device, operator can then be examined, and whether knitted fabric corresponds to demand or expectation.If It is unlikely to be such situation, the changeable setting for tension of operator.

Preferably, the yarn warp let-off value of yarn feed drive device is indicated.Yarn warp let-off value, example are generated from yarn tension Such as the every lacquer of mm/R, i.e. millimeter.When knitted fabric has desired appearance and desired tactile, the yarn warp let-off value can be indicated, To use the yarn warp let-off value again in the production process later of identical flower pattern.Instruction herein can be optically via display Device carries out.But instruction can also be, printing or in other manners storage yarn warp let-off value.Important is only the yarn warp let-off Value later, that is in the production again of identical flower pattern for using and can be input in braider.

Preferably, preset maximum value is set with the percentage (Bruchteil) of a basic value.Basic value pair In can be set known to each machine and by manufacturer.Maximum value for example obtains from the measurement at corresponding tricot machine, wherein This is also contemplated that fluctuation.Then certain percentage of basic value can for example be set as tension.Therefore it is absolute setting is not needed Value.

The task solves in the following manner for the tricot machine for the type that beginning refers to, i.e. yarn tension measurement dress It sets and is connected with control device, which adjusts yarn feed drive device in the study stage.

As illustrated above in association with method, the yarn of the yarn of warp thread therefore can be measured using yarn tension measuring device Line tension and make the tension become adjustment yarn feed drive device yarn warp let-off value basis.Therefore, volume is on the one hand avoided Knit the overload of element and thread material.On the other hand, operator has the simple of the appearance and tactile for changing the knitted fabric generated A possibility that.Operator merely has to change theoretical value, and control device adjusts yarn feed drive device using the theoretical value.

Preferably, yarn tension measuring device is arranged at yarn balancing device.Yarn balanced component is raw in tricot machine It is necessary when producing knitted fabric, because generating the yarn consumption of fluctuation in stitch forming process.Inside the yarn consumption Fluctuation can be balanced via yarn balancing device.Now, the yarn balancing device can be used in a manner of simple, for surveying Take yarn tension." measurement " in the meaning of result numerically is often unwanted.Thread tension device can also It is arranged at the fixed part of yarn balancing device.

Preferably, yarn tension measuring device measures the total tension of multiple yarns.Thus it obtains on the width of tricot machine Certain balance.Thus the influence of each yarn and its tension is kept into smaller, and the total tension of multiple or even whole yarns Obtain meaningful magnitude.

Herein preferably, yarn tension measuring device measures at yarn guidance and tensile members (Fadenkreuz) Power.Yarn guidance and tensile members are the bar of elastic bearing in simplest situation, warp thread the yarn warp let-off to sley point Yarn guiding notch in front of, via the bar guiding warp thread yarn.When sley point is at its rollback point in knitting needle after When, then yarn guidance and tensile members have its maximum deflection.At the moment, maximum yarn tension can be measured.Yarn Power is herein preferably at fixed (feststehend) component, for example in the bullet of carrying yarn guidance and tensile members It is measured in region between property component and the bracket of tricot machine.

Preferably, yarn tension measuring device is synchronous with main shaft.Then yarn tension measuring device can just be said above Corresponding tension is measured at the time of bright, and there is the maximum distance of itself and knitting needle in the moment sley point.

Detailed description of the invention

The present invention is described in conjunction with the accompanying below with respect to a kind of preferred embodiment.Wherein:

Fig. 1 shows the extremely schematical view of a part of tricot machine, and

Fig. 2 shows the schematic diagrames of tension trend.

Specific embodiment

Tricot machine 1 (a part for presenting the tricot machine) has sley point 2, which is arranged in not further presentation Yarn guiding chase comb at.In addition, tricot machine has knitting needle 3, which is arranged at the knitting needle sley bar not presented further.In warp knit When machine is run, sley point 2 and knitting needle 3 are moved relative to each other, to form the coil of knitted fabric.Relative motion has so herein Section, i.e., move across the gap between knitting needle 3 in sley point 2 in the section, and there is such section, the area Ji Gai Longitudinal extend that sley point is parallel to knitting needle sley bar in section moves.

In such movement, the yarn 4 extracted out by warp beam 5 is processed into the coil of knitted fabric.

Yarn 4 is directed to the yarn guidance for being configured to bar 6 and tensile members.Bar is supported at elastic parts 7.When yarn 4 Tension change when, elastic parts 7 allow bar 6 certain mobility.Such tension change forms circulation for every coil It generates at least once, as this can be as learning in Fig. 2.

Fig. 2 shows the first curve 8 (tension that first curve reflects each yarn 4) and the second curve 9, (this second Curve reflects the corresponding tension trend of whole warp thread).The tension trend presented in curve 9 can be surveyed from the movement of bar 6 It takes.In this regard, being disposed with sensor 10 at elastic parts 7, which measures the tension of elastic parts 7 and therefore measures by bar 6 are applied to the power on elastic parts 7.Certainly it also it is possible that using another sensor, is formed to measure by yarn 4 The tension of warp thread.Sensor 10 can be formed for example by strain measurement item, which is arranged in the bracket 18 of tricot machine Between the retainer 19 of elastic parts 7 being fixed at bracket 19.Sensor is therefore located at immovable component and sensing Device is located at the element-external of the direct guidance yarn of tricot machine.

Sensor 10 is connected with control device 11.Control device 11 is connected with the yarn feed drive device 12 of warp beam 5.

Tricot machine 1 has main shaft 13.Main shaft 13 is responsible for most of movement of braiding tool.Main shaft especially controls sley point 2 With the movement of knitting needle 3.In brief, one turn of main shaft 13 in most cases promotes stitch forming process, hence for master Each reincarnation of axis 13 is at coil column.

Rotation angle sensor 14 detects the turned position of main shaft 13 and the turned position is equally notified control device 11.

It is not presented fabric traction device further, the knitted fabric of formation is using the fabric traction device from passing through sley point 2 and knitting needle 3 formed working region in extract out.

When tricot machine puts into operation, yarn 4 is threaded into sley point 2.This is usually in the situation of yarn guiding chase comb disassembly Middle progress, in yarn guiding chase comb disassembly, sley point 2 can be had better access to.After yarn is threaded into, yarn guiding chase comb is being brought to it just It is assembled at normal operating position and at this.Then machine is slowly placed in movement and is first checked for, sley point 2 by operator Whether gap knitting needle 3 between can be travelled across, without colliding.If being likely to require amendment.

Then operator implements first coil forming process first.Hereafter, yarn 4 is tightened manually.Hereafter it is followed by one A or multiple other stitch forming process, until forming at least one continuous coil column on the working width of tricot machine 1. Between each stitch forming process, yarn 4 is tightened manually.

When carrying out the formation of continuous coil, the yarn feed drive device 12 of warp beam 5 puts into operation.Then warp beam 5 conveys Yarn 4.Then coil is formed first blockingly, that is to say, that coil is closely against each other.Hereafter, what is do not presented further knits Object pulling device puts into operation and can start the production of fabric.

But this is the following is prerequisite, i.e., certain parameter of the production of known knitted object, particularly for so-called The value of the yarn warp let-off, the value are typically illustrated with mm/R, i.e. millimeter every lacquer.In addition to the movement of actual band yarn and loop density Other than (it can be influenced by fabric traction device), the yarn warp let-off is the important value in knitted fabric production.

When that should generate new flower-shaped, the value of the yarn warp let-off is not for using.The yarn warp let-off is with the experience and feeling of operator To adjust.Here, being generated in each work step through operation error and lacking risk caused by professional knowledge.It thus can be Damage is generated at knitting element, that is, sley point 2 and knitting needle 3.In addition, yarn 4 can also be damaged.

In order to mitigate the problem, the tension of the yarn 4 fed is measured by means of sensor 10 and transfers the actual tension It notifies to control device 11.Control device 11 compares actual tension with the theoretical tension that can be set, and so adjusts now Yarn feed drive device 12, i.e., so that being no more than theoretical tension, which is can preset maximum value.

When yarn feed drive device 12 is so steered, i.e., so that the every lacquer of yarn feed drive device send more yarn 4 i.e. When biggish length of yarn, then tension declines.When yarn feed drive device 12 so drives, i.e., so that yarn feed drive device When every lacquer conveys less yarn, that is, lesser length of yarn, then tension improves.It can be real by the processing mode of the automation Existing, tricot machine is to a certain extent it may be said that itself is gropingly close to the right value of the yarn warp let-off.

It, should " learning process " continuation when fabric traction device starts and coil becomes much larger.Accordingly, for each coil Also the larger lengths of yarn 4 are brought.Correspondingly, yarn feed drive device slightly must quickly rotate warp beam 5, so as to needle To the larger lengths of every stitch forming process delivered yarn 4.Tension is also measured herein and yarn feed drive device 12 is so adjusted, I.e. so that being no more than maximum tension.

Tension is not necessarily as absolute value input.Each tricot machine 1 usually has basic value, and the basic value is for example by manufacturer Setting can be measured when tricot machine puts into operation for the first time.Then operator can set such as base via input unit 15 The percentage share of plinth value, i.e. percentage, to adjust maximum tension.Operator then can be visually or by feeling inspection It looks into, whether which has generated the desired quality of knitted fabric.If such situation is unlikely to be, via input unit 15 changeable percentage values.

Once knitted fabric is produced with satisfactory quality, the value of the yarn warp let-off is just indicated via display device 16.Display Device is schematically presented herein.It centainly uses display herein or printer is not inevitable.Also it is possible that only storing yarn The value of the line warp let-off, thus then the value of storage is used for production process later.

Then the knitted fabric comprising identical flower pattern later can be produced using the value of the yarn warp let-off.

Discribed process preferably carries out during tricot machine is run with crawl speed, so that operator can be It is constantly checked in the situation of slow speed, actually whether to the appearance of prestige and desired tactile production knitted fabric.

Yarn balancing device is formed with the guidance of the yarn of bar 6 and elastic device 7 and tensile members, needs this at runtime Yarn balancing device, to balance the yarn consumption fluctuated in stitch forming process.It now can be additionally flat using the yarn Weigh device, constantly to measure the tension of yarn.

As can be learnt from the curve of Fig. 2, the quite significant earthwave of the tension of yarn 4 in stitch forming process It is dynamic.This is because yarn consumption equally fluctuates in stitch forming process.Rollback point after sley point 2 is in knitting needle 3 Place, more specifically when on this side of the hook portion 17 of knitting needle 3, tension is maximum.Here, sley point 2 has most relative to knitting needle 3 Big deflection.By detecting the rotation angle sensor 14 of the angular position of rotation of main shaft 3, now it is possible that detecting sley point 2 The position, so that control device 11 equally only detects corresponding tension value at the time point.Control device 11 is therefore in certain journey It may be said that forming the snapshot of tension at following time point, i.e., main shaft 13 is located at preset angle of rotation position at the time point on degree In setting, and at the time point only by tension with it is preset or can preset maximum value compare.
