Description
Technical field
The utility model relates to a kind of constant linear velocity tenslator, is specifically related to a kind of open width coiling constant linear velocity tenslator, belongs to the sheet-like article permanent tension control technology of reeling.
Background technology
The sheet-like article that comprises line, fabric, adhesive plaster, people's leather, plastic sheeting, paper in carrying out open width winding process process, all relates to the tension force of debatching, rolling and the control of linear velocity.
For the dye gigging technology of fabric finishing industry, the tension force of its fabric debatching, rolling and linear velocity control will directly influence fabric front and back aberration and left, center, right aberration.For this reason, the utility model mainly is to make improvements at the tenslator that the included open width of prior art dye gigging technology is reeled.
The open width wind2 as shown in Figure 1.Can understand by accompanying drawing 1, work as motor M
2Rotation speed n
2Invariable, then in its winding process, along with the continuous increase of rolling coil diameter D, fabric movement linear velocity V
2With proportional increasing; Tension force F will be linear growth with the increase of coil diameter D.This inconsistent of fabric front and back tension force just occurred, and the aberration of fabric before and after directly causing.For fear of the generation of described aberration, open width dye gigging technological requirement after described open width wind2 starts, should keep fabric movement linear velocity V
2Constant, make fabric tension F constant, this just requires motor M
2Rotation speed n
2Be inverse proportion descends along with the increase of rolling coil diameter D.This relation spiral characteristic that is referred to as winding machinery in the field of business.This coiling characteristic curve as shown in Figure 2, it is a hyperbola.
Since fabric be have certain thickness, thereby on-line velocity V
2Under the constant situation, to large winding diameter, in order to obtain same coil diameter increment, the time of its required package is different from little coil diameter.For this reason, want to keep fabric movement linear velocity V
2Constant, this just must know instant coil diameter, and realizes linear velocity V by the rotating speed of adjusting motor M 2
2Constant.
Because dye jigger is alternately finished dye gigging technology by debatching, 2 main drive rollers of rolling.And rolling speed is constant, can guarantee the conformability of Fabric impregnation dye liquor time, thereby obtains the dye-uptake of uniformity.And the reaction of the fabric fixation of dye gigging technology is carried out in package.Thereby, decide the tension force debatching and can guarantee fabric homogeneous band liquid, can not cause wrinkling rolling.This is the place of described permanent tension force and linear velocity control positive role.
In order to know coil diameter immediately, to regulate motor M
2Rotation speed n
2, this just requires to carry out immediately the measurement of coil diameter, the conventional 3 kinds of methods that mainly contain of calibrating;
A kind of is the linear velocity method of calculation, this method adopts the frequency converter with Tension Control function, carries out tension force by the PLC programmable controller and sets, by linear velocity trans feedback line speed signal, the instant adjustment received (moving back) winding up roller drive motor rotating speed, to guarantee fabric movement linear velocity V
2Constant.But this method not only requires it to have operating parameters memory store function before stopping, and because skid " the throwing switch " on the included roller that tests the speed of fabric on-line velocity sensor device part, and cause the unfounded of speed sampling signal.Especially because the difference of fabric thickness, and along with the variation of tension force, factor such as expanded level is inconsistent behind the belt strap liquid, and be difficult to record the true line speed of debatching.Add and only use the built-in tension function module of frequency converter, its Tension Control precision is in 5～10% scope, and this does not meet the dye gigging technological requirement.
The method of another kind of measurement of film reel diameter is the thickness product separating method.This method of calibrating is to calculate instant coil diameter in real time according to the note ring signal.This method is because fabric thickness is a uncertain factor, thereby its control accuracy is also not ideal enough.
The third is direct caliper measure.This direct caliper measure adopts feeler lever and super sonic or CCD pattern sensor, and coil diameter is measured immediately.Though the coil diameter of this method is to have surveyed standard, its control is followed coil diameter by motor speed and is made linear change.Its control curve almost is bar straight line (as shown in Figure 3), and this does not meet the winding machinery characteristic curve, so that fabric movement linear velocity control accuracy inaccuracy.This is present city for reflecting the yardage roll serious major reason of aberration defect in aberration and the limit end to end in the huge dye jigger production.
In sum, the constant linear velocity constant tension control device of prior art dye jigger, it is poor all to exist control accuracy, does not meet the winding machinery characteristic, so that causes yardage roll deficiency such as aberration in aberration and the limit end to end.

K=f (D)) is overlapped into same curve with curve 1 (n=f (M)), make the output speed of rolling, debatching drive motor, controlled by actual winding machinery characteristic, realize dye gigging technological process rolling-debatching-rolling ... move again and again by same processing line speed, thereby realize the purpose of this utility model.
For above-mentioned conception, the utility model realizes that the technical scheme of its purpose is:
A kind of constant linear velocity tenslator that is particularly suitable for dye jigger tension adjustment posture tenslator phase configuration, comprise the rotating shaft of tension adjustment frame boom, drive receipts, the motor of debatching roller and the frequency converter that is electrically connected with described motor, its innovative point is, also comprises:
One excitation curve plate; Excitation curve plate and the quiet connection of described rotating shaft that is in the rotation zero-bit; The segment of curve of excitation curve plate is to meet winding machinery characteristic curve μ
KThe curve of=f (D);
The electrical quantity sensor of the linear output of one analog quantity; The segment of curve of described electrical quantity sensor and excitation curve plate is directly faced and is provided with, and keeps spacing between the two; The mouth of described electrical quantity sensor is electrically connected with the frequency converter input end; Electrical quantity sensor accepts the excitation curve plate and the spacing between it changes, to frequency converter output μ
K=f (D) hyperbola changes electric quantity signal, makes the described motor speed of the instant adjustment of frequency converter frequency conversion.
Can understand by above given technical scheme, the utility model is that the boom rotating shaft with existing equipment tension adjustment frame extends to outside the dye jigger cylinder body, adopt the angular displacement signal of boom, relative displacement by excitation curve plate and electrical quantity sensor, electrical quantity sensor is accepted the excitation curve sheet separation and is changed, and output μ
K=f (D) hyperbola changes electric weight, changes the output frequency of frequency converter, and the instant rotating speed of receiving (moving back) volume drive motor that changes is realized the control of fabric movement constant linear velocity, thereby realized the purpose of this utility model.Said motor can be a common electric machine, also can be variable-frequency motor.
The utility model is a kind of electromechanical integrated device, has mechanical memory function during parking, and the convenient process speed of pressing is once more driven; Electrical quantity sensor is ripe standard electronic product, has output linearity height, becomes advantages such as the level and smooth and waterproof of the amount of sending, solar heat protection, good in anti-interference performance.The boom angular displacement that the excitation curve plate can be constituted according to dye jigger maximum coil diameter and different coil diameter, design meets winding machinery characteristic curve μ
K=f (D) curve, simple for production; And be fixed on " zero-bit " of boom rotating shaft with screw very easily.
Further innovative point of the present utility model is:
Also comprise can with the lifting mode tapered tension micro-adjusting mechanism of 2 underliquor guide roller phase configuration; Described tapered tension micro-adjusting mechanism; By lifting jockey pulley, sprocket wheel, chain, cylinder assembly, can form by the reducing valve and the speed difference transmitter of control mechanism control with source of the gas pipeline bonded assembly; The lifting jockey pulley can be moved up and down by the fabric draw by 2 underliquor guide rollers; Lifting tension force roll shaft and chain one end link, the chain other end via be bearing on the vehicle frame and the sprocket wheel of rotating rotating shaft static connection and the binding of cylinder assembly piston rod; Reducing valve is connected with the cylinder assembly pipeline; Speed difference transmitter and the sprocket wheel interlock that drives by chain; μ by the output of speed difference transmitter
KLock signal, by the rotating speed of frequency converter regulation and control receipts, debatching roll drive motor, fine setting is received, both linear velocities of debatching reach consistent with each other.
We can be understood that by fabric warrping dyeing technique process fabric will travel forward through some fabric guide rolls (passive) and spreading roll (fixing).And fabric must overcome the additional tension that its friction resistance moment produces when the passive fabric guide roll of draw; And fabric passes through the fixedly formed cliding friction of spreading roll, removes to produce radial tension, also produces weft tension simultaneously.The above-mentioned fabrics mechanicalness tension variation that produces in service directly has influence on the homogeneity of belt strap liquid, during especially by spreading roll, will directly influence the homogeneity of fabric width band liquid, and this is the major cause that causes the left, center, right aberration.
Because the existence of described lifting mode tapered tension micro-adjusting mechanism is as debatching roller linear velocity V
1During less than the wind-up roll linear velocity, the lifting jockey pulley descends; Work as V
1＞V
2The time, the lifting jockey pulley rises, and works as V
1=V
2The time, the stop motion of lifting jockey pulley.Should be noted that here cylinder assembly is the equal of a counterweight.The dipping and heaving of lifting jockey pulley drives sprocket rotation, and exports μ with the speed difference transmitter of sprocket wheel interlock
KFeedback signal is regulated the rotating speed of described drive motor by frequency converter, until V
1=V
2Till.
Because debatching roller and wind-up roll are all directly calibrated the constant linear velocity control that meets the winding machinery characteristic by aforementioned, thereby the stroke of the lifting jockey pulley of this lifting mode tapered tension micro-adjusting mechanism is short, belongs to the regulation and control of speed elementary errors.Not only it takes up space for a short time, and can eliminate the tension force that debatching and rolling produce because of the dead slow speed difference.Meanwhile, the initial tension when described counterweight cylinder assembly can be set fabric by the lifting jockey pulley, for example, cloth coil coil-diameter ratio is 1: 4 o'clock, its when minimum coil diameter cylinder assembly by reducing valve feed-in 0.2Mpa pressurized air; To the balancing force of lifting jockey pulley generation 400N, remove lifting jockey pulley deadweight 200N, then the fabric single load bearing is 100N, this is the initial tension of fabric.Ascending when the cloth coil diameter, the compressed-air actuated pressure of reducing valve feed-in cylinder assembly is reduced to 0.15Mpa by 0.2Mpa, and the fabric single load bearing is then reduced to 50N by 100N, thereby forms the tapering Tension Control.Fabric tension has decrescence effectively compensated the rolling coil diameter and has increased the tension increment that causes spreading roll.
The control mechanism of described reducing valve comprises first gear and second gear; First gear and the quiet connection of boom rotating shaft, the quiet connection of manual axle of second gear and reducing valve, first gear is meshed with second gear; By the angular transposition of boom rotating shaft, drive the manual axle of reducing valve, realize the adjusting of reducing valve supply gas pressure.What this technical scheme provided is the preferred reducing valve control setup of a kind of the utility model institute.But being not limited to this, by the manual control setup etc. of axle of PLC control Electromagnetic Drive reducing valve, also all is good for example.
