Abstract
The present invention discloses a method and for implementing the equipment of this method, is used to monitor by means of extrusion head make the rubber be made up of one or more mixtures or the long profiles of thermoplastic.Extrusion head is with one or more single lead screw ex truding briquetting machine feed, and at its port of export the measurement device that shows pressure and temperature is housed.When the section bar band has departed from by the given every meter gravimetric value of demarcation of every meter heavy surely scale, controller just detects instant nip pressure and extrusion temperature at nozzle exit end, and when departing from the calibration value of adjusting immediately, controller just produces regulating action to the rotating speed of relevant single lead screw ex truding briquetting machine.
Description
The present invention relates to be according to the preorder of claim 1 partly method and according to the equipment of the preamble of claim 2.
The manufacturing equipment of the liquid band of being made up of two kinds of different rubber compositions has been known in DRP specification DE-PS2201631.The fly press of two stack settings operates in the injector head, material is combined in injector head flows band and extrude it (seeing United States Patent (USP) us-PS2,382,177).
The liquid band that squeezes out is passed through a belt conveyer scale of demarcating weight, and when departing from demarcation weight, for example: the drawing velocity with liquid band when demarcation weight is too high improves, so that reach the purpose of reduction weight by stretching.
In practice, liquid band equipment is to move with higher slightly discharge rate, and the liquid band that will squeeze out reaches its demarcation weight by stretching.
Such equipment, as the possibility of regulating only is can provide certain elongation to pushing the band that flows by improving or reduce draw speed, at this moment, liquid band is considered to the minimum speed of liquid band stretcher from the muzzle velocity of nozzle, should not reduce downwards in order to adjust this speed of section bar thickness again.
Carry out the adjustment of this sample by demarcating weight belt conveyor scale, it is too slow to work together, for example: if confirm that with scale the weight of liquid band is higher, so there has been one section very long liquid band not used, and when proofreading and correct this defective, a lot of useless section bar material occurred extraly.
Yet bigger as can be seen shortcoming is: the belt conveyer scale only can be measured the summation of extrusion modling productivity ratio, and can not grasp each productivity ratio of extrusion modling.If following, for example the single lead screw ex truding briquetting machine of injection vehicle sidewall ejects material on the high side, and in other words, the belt conveyer weigher has been confirmed material on the high side, so just improves draw speed.
By this measure, cross the demarcation gravimetric value that some times just reach liquid band afterwards again, still bear second extruding mixture, for example the rolling surface of wheel tyre by the upper compressive make-up machine.
Although the demarcation weight that liquid band is abideed by, each mixture exists different proportionate relationships each other, and it can cause the remarkable weakening of vehicle tyre.
Because the liquid band of common vehicle tyre is made up of three kinds and more kinds of different mixture even, so by means of the adjustment of belt conveyer weigher with gratifying function liquid towards band itself, the mutual part by weight of each mixture can not cause satisfactory result.
Be certain to search out a kind of solution, by means of it, not only the total amount of liquid band but also each component all can monitor and control the rubber composition that is combined into the band that flows in injector head.
Section bar manufacture method of being made up of a plurality of mixtures and equipment is at U.S. Pat-PS4, and is known in 097,566.
The section bar band that flows out from section bar band nozzle is through a measurer for thickness, is input on the transport tape after turning to 90 ° then, at this moment, off and on the distance of the guide ring that turns around of section bar band measured.The type band by every meter weight scale guiding, and is admitted by a conveyer belt that places its speed-controllable system at its rear according to required gravimetric value and to be imported after through the pulley of beating.The section bar band is transmitted the band elongation or has forged weak point when low excessively gravimetric value when too high gravimetric value, so that reach the demarcation weight of profile shapes.
What shown method adopted is automatic control technology, thereby be very expensive, and in addition also has a shortcoming in principle, if such as one of one of every meter weigher or guide ring distance-measuring device have assert that the section bar that has made does not meet required size, so must be by stretching or forging the short section bar of forming by two kinds of mixtures and bring and compensate.
Each drawing process for example by quickening conveyer belt, can cause the size that the section bar band is coarse and can not control, and just showing when this uses afterwards is potential weakness (fault).
Another shortcoming is: the time point that plays correction from the time point of determining to depart from section bar bandgap calibration weight ends, there have been a lot of materials to become waste product by equipment, because in instant measurement point and source of error or depart from and have many section bars to run between the calibration value point, and these bands can not re-use.
Task of the present invention is to point out a kind of method and an equipment, can avoid above-mentioned shortcoming thus, should guarantee: can promptly revise and demarcate the deviation between weight or revise the overall dimensions of whole section bar rapidly, can implement if especially revise its word one of forming by many different mixtures of each composition one of section bar, so that produce useless profile length as few as possible.
At this moment should get rid of each natural influence to the section bar band of manufacturing, the section bar band is a kind of unfavorable means to thickness correction because for example stretch, and in addition because each drawing process when the cooling section bar, can cause certain uncontrollable retraction.
This task reaches by the described method feature of characteristic in first claim and is resolved by the described equipment of characteristic in second claim.
By detecting the instant nip pressure and/or the extrusion temperature of each mixture, for example when arrival end enters the multichannel nozzle, if every meter calculating scale has been assert departing between the section bar band of extruding and calibrated length weight, just determine the quantity delivered of each single lead screw ex truding briquetting machine, allow to charging rate so according to its each single lead screw ex truding briquetting machine separately of quantity delivered.
By this measure, the section bar band is got back to every meter weight of its demarcation again, and the combination of materials composition of whole section bar band also gets back to it and demarcate component, and this demarcation component is related for departing from of section bar band whole calibrating weight.Can guarantee that thus fixed material component accurately observes the weight of whole section bar, and need not to implement physical action the section bar that has sprayed.This effect is followed and is come known shortcoming, for example: produce uncontrollable retraction at cooled region when above-mentioned section bar band extends, to reach the attenuating of weight.
Determined and demarcated deviation between weight when every meter weight scale, then can replace pressure and the temperature of measuring each single lead screw ex truding briquetting machine port of export selectively.If with the deviation of calibrated length weight, also can only detect the pressure of each single lead screw ex truding briquetting machine.There is a slighter pressure to descend if for example on a single lead screw ex truding briquetting machine, assert, if calibrated length weight is too little, this kind identification means following situation and is so: this single lead screw ex truding briquetting machine has been carried the material that lacks some a little than other single lead screw ex truding briquetting machine.By improving this single lead screw ex truding briquetting machine screw speed slightly, just can improve inlet amount, return to the weight of demarcation so again.
If except pressure detects, also carry out temperature detection, then can obtain better and more reliable result at each single lead screw ex truding briquetting machine port of export or in nozzle import department.
Can the viscosity of material of mixture in each single lead screw ex truding briquetting machine be taken in better by temperature detection.
Such as when detecting single lead screw ex truding briquetting machine, confirmed that according to the rising of calibrated length weight the temperature of a single lead screw ex truding briquetting machine raises, and not have record to reduce and the pressure decline that produces based on viscosity, this just indicates: this single lead screw ex truding briquetting machine discharging is too many.When temperature raise, viscosity of material reduced a little, and therefore the pressure in test point also slightly descends.Although do not note because pressure is descended, still can draw thus: this single lead screw ex truding briquetting machine exists giving of auxetic material slightly, in other words, because the rising of temperature brings the limited decline of viscosity of material, improve the ability of giving by this single lead screw ex truding briquetting machine and compensate.
Departing from every meter weight of demarcation determines by a demarcation actual value comparator.And be defeated by controller again, for example be a process computer.Earlier with the process computer programmed so that when this kind occurring and depart from, detect the actual value of material temperature and pressure at once, this value can be immediately at the input of nozzle or at spiral syringe place, collect by corresponding temperature and pressure scanning sampler, and compare with calibration value.
If controller has been determined an actual value that departs from calibration value on a sample point of pressure and/or person's temperature, then controller works to single lead screw ex truding briquetting machine corresponding driving device, and this drive unit is to should test point disposing.
Controller is designed program like this, and for example the deviation when between pressure and calibration value descends, and (1 crust equals 1.020 kilograms per centimeter to 0.5 crust
2), in other words, be under the decompression situation, so just the screw speed of single lead screw ex truding briquetting machine improves 2 revolutions at that time.
Thus, this single lead screw ex truding briquetting machine has been given many slightly materials, and the material pressure at the nozzle entrance point for example 0.5 clings to regard to rising again like this, and arrives above-mentioned calibration value.Owing to improve the feeding ability of this single lead screw ex truding briquetting machine a little, then the weight of section bar band returns to calibration value again simultaneously, and this calibration value is that the demarcation/actual value by every meter weight scale is relatively determined.
With this kind mode, the demarcation weight of the extrusion modling band for example be made up of three kinds of different mixtures adjusted again rather than must be the band directly generation effect in any way of extrusion modling itself.
An embodiment contrasts accompanying drawing and is illustrated, but the present invention is not limited.
Fig. 1 is the schematic diagram with three single lead screw ex truding briquetting machines of a control loop.
In the multichannel injector head 1 of a liquid band, for example there are three nozzles 2,3,4 working, they can pass through various rubber composition, come feed by three single lead screw ex truding briquetting machines that separate 5,6 and 7 respectively.
Input in nozzle 2,3 and 4 is installed with measurement mechanism 2a, and 3a and 4a are used for carrying out the measurement of pressure and temperature.
On controller 8, the instant calibration value of pressure and temperature can be adjusted and compare with instant detected actual value.
Further pass through connecting line 5a, 6a and 7a are connected the drive unit of single lead screw ex truding briquetting machine 5,6 and 7 with controller 8, so as to adjust calibration value and and the actual value of screw speed compare.On controller 8, also can adjust the instant calibration value of screw speed.
Also have every meter weight scale 9 in addition, be used for detecting the actual weight of the mobile band of forming by three kinds of different mixtures 10, also receive on the controller 8.
On controller, also can adjust the demarcation weight of every meter weight scale 9 of change.
The mobile band of being made up of three kinds of mixtures 10 that comes out from 1 extruding of multichannel shower nozzle flows through every meter weight scale 9.Deviation between every meter mobile band and predetermined demarcation weight is determined by controller 8.
For example every meter weight is very few has shown the material that comes out from one or more shower nozzle 2,3 and 4 extruding very little.
If controller 8 has been confirmed a value that every meter weight is too little, controller 8 is checked pressure and the temperature actual value in each nozzle 2,3 and 4 at once so.
Descended if confirm the pressure in nozzle 2, in other words, be lower than calibration value, this just means so: the material that single lead screw ex truding briquetting machine 5 is provided is than predetermined lacking.Therefore, the mobile band of being made up of all three mixtures just becomes lighter.
Also must detect together temperature simultaneously, because for example when temperature raises, then viscosity of material descends, and in other words, it is thinner that material becomes, and for this reason, measured material pressure has descended, and can not make the quantity of material of giving tail off thus.Therefore every meter weight scale is confirmed not change.If but the pressure of scanning sampling has descended, and do not have the rising of temperature, this just means: the quantity of material by the single lead screw ex truding briquetting machine screw rod transmission has reduced.
If not only the instantaneous sample of the instantaneous sample of pressure but also temperature all descends with predetermined value, and confirmed these numerical value by controller.So just at once to screw speed adjusting device generation effect.
Instant detected pressure and temperature value are tried to achieve by controller 8, can consider that these two values are used for controlling corresponding part by controller like this.
The every meter weight of band of flowing just in time reduces is to get very little this part by single lead screw ex truding briquetting machine 5 feed.
On the low side based on every meter weight having confirmed mobile band on the one hand, on the other hand based on the low side in pressure and temperature that nozzle 2 places of single lead screw ex truding briquetting machine 5 record by measurement mechanism 2a, controller 8 correspondingly improves the rotating speed (for example 1.5 revolutions) of single lead screw ex truding briquetting machine 5 this moment, this single lead screw ex truding briquetting machine has the extrusion capacity that increases slightly again like this, up to the given demarcation pressure in nozzle 2, and temperature recovered, and recovered every meter weight of demarcation of mobile band 10 thus.
After leaving every meter weight scale 9, the band 10 that flows arrives and enters the constriction zone that does not indicate among the figure, and it is made up of two tilting rolling conveyor zones.
The then mobile band 10 that moves on again enters cooled region, and and then is to enter in the equipment of sizing.
