Description
Technical field
The present invention relates to a kind of weaving unit of weaving loom, textile mills' process equipment especially, such as gigging machine or drawing frame, ring spinning frame, pneumatic spinning machine or wing cushion roving frame.Weaving unit on these equipment has comprised several lower rolls and has been interacted to the load device of the material that will weave by top roll.For the step that in lower roll or the top roll is produced load and operates such weaving unit.
In addition, be processed into uniform fibers band as far as possible in order to make textile raw material, the weaving unit of weaving loom has carried out corresponding setting.There is row's drawing mechanism the weaving unit, is the adjacent roller in several front and back generally speaking to form, textile raw material roller between to prolong the so-called in a lateral direction clamping lines of conveyer belt clamped.Because roller is to demonstrating pitch speed different and that on direction of transfer, increase progressively, the textile raw material of forming by one or several fiber band processing of being weaved at last, and carried out size simultaneously relatively.
Except correct selection pitch speed, the up-down rollers that has influence on the weaving unit also can exert an influence to the quality of fiber band with the textile raw material load pressure that will weave.In view of this reason, the load device of weaving unit is provided with, and load coefficient is arranged to desirable numerical value before fabrication processes begins, and this numerical value is decided according to the textile raw material that will weave generally speaking.
Background technology
Corresponding D E 33 25 422 A1 have described the load device of weaving unit, and its load cell is the unit of pushing by pressurizing unit control, such as cylinder form.Load pressure can be changed after replacement of products, in order to consider the variation of property of raw material.
To this Comparatively speaking, DE 197 04 815 A1 also stress, for example through cylinder simultaneously the assistance of regulating relevant pressure-regulating valve can control down adjustable individually on the pressure roller load force.
Even load force meeting counter extensioin pressure roller even the stretching material regulated in the said machine at that time exert an influence, still, in order to continue to improve the quality permission improvement peak load power existence of product.Therefore charger perhaps more precisely is that the charger method of operation is exactly the purpose that proposes this invention.It make as much as possible lower compression roller load force on the reliable adjustment and special silk thread quality that equates become a kind of maybe.
Summary of the invention
In view of load operating method, the grade of load on basis can be regulated through weaving loom lathe data and/or expanded material data and also be about to solve under the assistance of operating system.Thus, silk thread quality of improve producing and the uniformity that particularly has a notable feature are very possible, because operating system can be considered the data that change the more definition under various most, and can regulate contiguous by the load of definition of data.On pressure roller and to the influential pressure of stretching silk thread, can be used for preparing burden always.
The content of comparing all descriptions with state-of-the art is a great advance, because pointed out the inhomogeneities of the material that in most of the cases stretches here, can consider in real time that again the stretching material is inhomogeneous simultaneously.The possibility of result is that load force must guarantee will remain on the minimum level line fully in the pressure roller, guarantees that the locking device of stretching material between last lower compression roller is reliable and secure at present.Because because the extruding force of friction generates trace and a small amount of surface temperature of pressure roller exist simultaneously always, compare with conventional equipment like this, can realize the revolution that reaches higher at maximum surface temperature charger pressure roller.
The raising of final charger revolution makes the spinning preparation machine speed of production that improves equipment (for example become a kind of possibility; Gigging machine or drawing frame; Ring spinning frame, the speed of open-end spinning frame or wing cushion roving frame), product quality also can get a promotion simultaneously.
Favourable part is; If service time and/or temperature that the lathe data comprise running time and/or charger be surface temperature especially; Pressure roller and/or a lower compression roller at least one; This just shows, can cause product quality to descend when drawing process begins after charger does not move for a long time.Can reduce the temperature of pressure roller on the charger especially in the downtime, because can keep its whole temperature in surface at temperature constant state lower compression roller upper surface.The most special advantage is during the startup stage of drawing process, in order to ensure the reliable locking device at this stage fiber material, can improve on pressure roller the grade of load with fibrous material.Seeing that roll wear in order to realize above-mentioned advantage, finally can be adjusted to a littler numerical value with the load force that relies on running time or roller temperature.
Load is provided with and can stepless in all cases or progressively carries out.Load is provided with the pitch speed that top roll load (measured value and actual value) and up-down rollers can be set; The weaving peak width, (predraft zone central roll is to the distance of clamping lines, and the inlet roller of main stretch zones is to right with intermediate calender rolls; Intermediate calender rolls to the supply of material roller to); The degree of drawing that single roller is right, the size of total degree of drawing and other all variablees of weaving unit.Just the concrete running parameter of weaving loom does not belong to device data, more is to be appreciated that with the relevant data of production process.Some signals also belong to device data, such as: because the procedure fault signal that the conveyer belt fracture shows, some also belong to device data by the external data that preposition or rearmounted weaving loom provides.
This also is an advantage, and the data of the material that weave comprise thickness, humidity; Temperature, the coefficient of friction between fiber and the fiber, upper surface quality; Such as the moisture (especially in cotton textiles) that exists and the characteristic and the quantity of gloss, fibre length, purity; Characteristic, length weight or want the uniformity of textile material.Because so-called size fluctuates under given conditions, so can reach a kind of balance to load setting through the control system, this balance makes fiber band more even.
It has also brought benefit to self equally; When the data of wanting textile material can be at the inlet of weaving unit; Outlet; Or calculate between the road of gateway, load coefficient can be provided with roughly on the basis of the numerical value that inlet calculates, and the calculating through outlet calculating and gateway accurately is provided with again.Be provided with and in so-called open loop or closed loop, carry out.
Advantage is device data and wants the data of textile raw material to detect by sensor.These sensors comprise the UV sensor that can detect the attribute of wanting textile raw material, infrared ray sensor and microwave remote sensor; Temperature sensor; Velocity sensor; Sensor that can the acquisition environment condition, such as air humidity; Or pressure sensor.
The detection data of several sensors is interrelated also to be an advantage, because the quality of fabrication processes not only depends on parameter.In fact in order to obtain high-quality, any one relevant device data all must be considered.
The deeper advantage of this invention is to weave the unit after the conveyer belt fracture, can rework through improving load gradually.After result of variations is come out with the corresponding data of wanting textile raw material (such as thickness and uniformity) variation, need reappose the fibrous raw material that to weave.The variation meeting of fibrous raw material thickness uniformity to final products in conventional steps exerts an influence.This invention can guarantee the even stretching in the thickness position through the load setting to weaving unit roller.Sent the material afterload can reset to low value at conveyer belt, the load of the load of fibrous raw material and relevant device parts can remain on the alap value like this.
The material of weaving is transported to weaving unit or model jar.After the model jar of adjustment conveyor-belt apparatus was changed, the weaving unit improved load gradually and works on.When the model jar was changed, the connection of corresponding fibre bundle made thickness produce variation.To stretch in order reaching as far as possible uniformly, can to improve load at short notice, this also is an advantage.Improving load can be through changing realization to data or the device data of wanting textile raw material in the control system, such as when the model jar was changed, respective sensor was changed the signal of generation.
More advantages are, the setting of can loading separately of top roll and lower roll can be optimized and revised each load like this, reduces the wearing and tearing of roller upper surface, guarantees as far as possible evenly to stretch.
Most characteristic is, what load can be by independent control, machinery, pneumatic, hydraulic pressure, electricly be provided with load cell electromagnetism.This component structure is very little, can very simply be integrated in the weaving unit.In addition, also can realize continuously or the load setting of short-term through the of short duration operate time.
The load of up-down rollers is depended in the setting of weaving peak width of weaving unit, because two right clamping distances of adjacent roller depend on the size of load.If load improves, clamping distance is forced to dwindle.Because the rubber of top roll is close to lower roll.The desirable clamping distance of single fiber is calculated, and weaving peak width relevant when advantage is high load capacity also becomes big.When load reduced during simulation, the weaving peak width also reduced.For fear of roller overheated with the damage fiber quality, be necessary depending on that load or the single roller of respective rollers upper surface temperature or the revolution of all rollers regulate.
The characteristics of weaving unit, its load device contain a controlled system control load cell, during equipment work, the load coefficient of load device can be adjusted by the explanation of control system, particularly diligent introduction.Load also can automatically adjust, and can regulate automatically continuously if desired.According to the current techniques situation, load such as wants the structure of textile raw material that change has taken place under special circumstances, can be manually through pressure-regulating valve or regulate bolt adjustment accordingly.Weaving loom allows to carry out work according to the above, and its these advantages can be with reference to corresponding chapters and sections in describing.
Under any circumstance, load cell is a machinery at least, hydraulic pressure, electric, the load cell of electromagnetism, this also is its advantage.Load cell pressure electrodeless or that progressively produce on roller can be very soon and is not needed manually to regulate.
The weaving unit comprises the sensor that at least one links to each other with the control system, and sensor is in order to calculate device data above-mentioned or to want the textile raw material corresponding data, and load coefficient can be regulated at these enterprising row in data basis.Process with the definite load coefficient of other modes also can be considered.Such as, will load in the put procedure in specific certain period and improve at the very start in put procedure, base load can be come out through other data computation.
Biggest advantage is that at least one sensor is placed on the inlet of weaving unit, between outlet and the gateway.The data of calculating can be carried out single or correlation analysis by the control system, for can be at the load coefficient of one of analysis foundation adjusted or all load cells.
Advantage is, several sensors measurement data interrelated.In order to obtain high product quality as much as possible, Several Parameters can be handled through the control system with this kind mode, proceeds to the load coefficient adjustment subsequently.
Advantage: device data has comprised the use and the downtime of draw-gear; Temperature, especially upper surface temperature are the upper surface temperature of one of them top roll or lower roll at least; The top roll load; The rotary speed of one of them top roll or lower roll, weaving peak width, total degree of drawing of degree of drawing between single top roll and the single lower roll and weaving unit.Especially after fabrication processes is stagnated a period of time, product quality often occurs and descend.This is that its adhesive force is also followed decline because the roller of weaving unit cools down.Can guarantee the clamping force at this section fibrous material in period through improving load coefficient period at this section, this also is the big advantage at the fabrication processes period of operation.Final load coefficient can be adjusted to a low numerical value according to working time and roll temperature, reduces the wearing and tearing of roller and improves process velocity through the rotating speed that improves weaving unit roller.
The advantage that also has is that the data of the material that will weave comprise thickness, humidity, temperature; Coefficient of friction between fiber and the fiber, upper surface quality, such as the moisture that exists and the characteristic and the quantity of gloss, fibre length; Purity, characteristic, length weight or want the uniformity of textile material.Under normal conditions, the material size always fluctuates, and this situation just can be considered when the adjustment load coefficient.
Another advantage is after the conveyer belt fracture, and it is ready to improve load weaving unit gradually by the control system.Reappose the fibrous raw material that to weave afterwards, just be placed on the so-called conveyer belt conveyer.The variation meeting of fibrous raw material thickness uniformity to final products in conventional steps exerts an influence.This invention can guarantee the even stretching in the thickness position through the load setting to weaving unit roller.Sent the material afterload can reset to low value at conveyer belt, the load of the load of fibrous raw material and relevant device parts can remain on the alap value like this.So need not go beyond the maximum positive temperature, roller still can turn round under the situation that rotating speed improves.
The same at least model jar of weaving loom links to each other, and the material that weave is transported to weaving unit or model jar.After the model jar of adjustment conveyor-belt apparatus was changed, the weaving unit improved load gradually by the control system and works on.Advantage can be with reference to above explanation with after conveyer belt fracture, corresponding load to be set the same.
Last advantage is, the setting of can loading separately of top roll and lower roll.Want the thin and thick position of textile raw material to be provided with according to the position of inside, weaving unit and the right varying strength of roller that has passed through.Through calculating actual value, can guarantee to produce fast the uniform final products of quality like this and when producing, product also played protective effect to equipment simultaneously being provided with separately of load.

In order to make all even successive stretching become possibility, it is right on frock, to have added 6,7,8 rollers, and stress element 16 demonstrates, and each roller is to all being along with each the common operation work of charger pressure roller.Roller is to can be by machinery, and is pneumatic, hydraulic pressure, and electronic or electromagnetic stress element constitutes, and under corresponding connection 17 is assisted, is connected with one of them operating system 13.Generally, control system 13 and operating means 14 such as keyboard, also have output unit 15, like display, connect.
In charger 1 exit, be close to a calender roller to 11 with oil can 12, installed one in addition and measured frock 9, indicate measuring chamber 10 measuring on the frock 9, when measuring, can sliver 4 sizes be counted.This size just thickness can change into a measuring-signal S2 through an electronic sensor that does not section out, and this measuring-signal can connect 17 through another and be transferred in the operating system, and evaluation calculates in operating system.Especially can the mean intensity of silk thread 4 and in silk thread 4 remaining inhomogeneous value count.If the silk thread that slides 4 does not meet the demands, in order in loading procedure, to regulate load level automatically, all can be delivered in the stress element 16 through a signal except stretching before and/or main the stretching,
A kind of in addition possibly be to appear at place thicker in the charger diverse location in the corresponding clear and definite lathe data and the change of stretching material data load.If it is with certain lathe data or the lathe data of confirming in real time or the stretching material data of confirming before is a condition, the load level that must improve by this way can remain on the reduced levels in normal loading procedure as much as possible.Therefore the result show this invention make the uniformity of stretching silk thread 4 become a kind of maybe because through the automatic adjusting of load level can for other charger 1 at a high speed or low cruise or the parameter during the actual loaded process use and regulate.
