It is conveyed to adjuster 15.Default weight per unit area is conveyed to adjuster 15 as rated value or control parameter 17, and will
It is compared with the second regulation parameter 14a for weight per unit area.
Due to adjusting deviation, adjuster 15 tries to achieve different default adjusting parameters, and these adjusting parameters are applied to different
Adjustment link 18,19,19 ', 19 ", 19 " ' ... on, these adjustment links influence fiber alignment and/or unit area weight again
Amount.
For the adjustment link 19,19 ', 19 of fiber alignment ", 19 " ' ... can be de- yarn roller 8, press roller 9,9 ' and/
Or the high dynamic servo-driver or Linear actuator of mixed and disorderly roller 10 (Fig. 3), by the adjustment link adjust these rollers 8,
9th, 9 ', 10 distances to each other and its differential.In addition servo-driver or Linear actuator can act as adjustment link 19, borrow
Help the size in the combing gap that the adjustment link is arranged at tambour 5.
Pressure yarn is for example carried out to copolymer of fiber suede 20 relative to the low peripheral speed of de- yarn roller 8 by press roller 9, and herein
Fiber is set to redirect in transverse direction.But, the pressure yarn of copolymer of fiber suede 20 causes the desired unit plane of then copolymer of fiber suede 20
Product weight is improved, and thus copolymer of fiber suede 20 becomes tightr and thereby produces small production length.This causes also to reduce follow-up setting
Standby speed of production.In order to compensate this unfavorable effect, can via before carding equipment 1 for weight per unit area
Adjustment link 18 reduce feeding fiber block amount, therefore the fiber block of more thin layer is transported on conveyer belt, but this is more
The fiber block of thin layer quickly guides carding equipment 1 into, so that the regulation parameter of weight per unit area 14a is again close to list herein
The control parameter 17 of position area weight.
By reducing the gap between de- yarn roller 8 and press roller 9, identical effect is realized.This also causes fiber in transverse direction
Redirecting for reinforcement on direction, thus improves the weight per unit area of copolymer of fiber suede 20, and so as to reduce production length.
Under both of these case, MD/CD ratios all become big.The multi-stag pressure yarn of copolymer of fiber suede 20 has the following advantages that：Can extremely accurate set
MD/CD ratios are put, wherein, the maximum effect to fiber alignment is produced by the differential taken off between yarn roller 8 and the first press roller 9.
Differential between first and second press rollers 9,9 ' improves desired result.
For example can be via the adjustment link 19,19 ' and 19 of servo motor " peripheral speed of de- yarn roller 8 is adjusted to
290m/min, is adjusted to 170m/min, and the peripheral speed of the second press roller 9 ' is adjusted by the peripheral speed of the first press roller 9
It is 140m/min to save, therefore obtains about 2 MD/CD values, so that obtaining the fiber alignment that MD/CD values are for 1.1.In the process
Period, for example, the adjustment link 18 for weight per unit area is improved, so that the regulation parameter 14a of weight per unit area is again
Adapt to the control parameter 17 of weight per unit area.
In the case where desired MD/CD values are 3.1, can be via the adjustment link 19,19 ' and 19 of servo motor "
The peripheral speed of de- yarn roller 8 is adjusted to 280m/min, the peripheral speed of the first press roller 9 is adjusted to 210m/min, and
The peripheral speed of the second press roller 9 ' is adjusted to 180m/min, therefore obtains about 1.6 stagnation pressure yarn ratio, so that obtaining
MD/CD is than the fiber alignment for 3.1.Equally herein, during the process, for example, the adjustment for weight per unit area is improved
Link 18, so that the regulation parameter 14a of weight per unit area adapts to the control parameter 17 of weight per unit area again.
The embodiment of the de- yarn unit of with the top and lower section according to Fig. 1, in the downstream of press roller 9,9 ' in transmission
The arrangement with the first measuring cell 13 has the following advantages that respectively in region with 11：Copolymer of fiber suede 20 is not yet enhanced just
By shredding until turning into single fiber.If two copolymer of fiber suede 20 are combined and fiber alignment is then just measured, that
Because different suede structures can produce the problem for making whole adjusted design scheme substantially become more sophisticated.This is especially in suction
The fiber of the advance opening for going out be transmitted back to due to the edge suction in carding equipment during when produce have a strong impact on, therefore
The fluctuation in bandwidth is no longer unified and/or can be appeared in fiber alignment.
It is to this alternative arrangement, what copolymer of fiber suede that measuring cell is disposed over and lower section was combined
In region, wherein, under the conveyer belt that measuring cell 13,14 can be arranged below, and so that from below below measurement
Copolymer of fiber suede 20.In the region of conveyer belt up, the copolymer of fiber suede 20 as usual from above the measurement of top.The arrangement
Very save space and can due to dead time for being changed but it is favourable.
Adjuster 15 advantageously refers to integrated characterisitic family adjuster, and it can depict complexity by means of fuzzy logic
Effective correlation.The adjuster 15 is simultaneously the integrated building block of the control device of carding equipment 1, the carding equipment
Therefore, it is possible to compensate the fault parameter for producing in the process, such as fluctuation or different fiber contents.Adjuster 15 is always
Only readjust the adjustment link 19,19 ', 19 step by step ", 19 " ' ..., wherein time interval of the adjustment to calculate
Carry out, the time interval is made up of time of measuring and dead time.For example the time of one second can be defined as time of measuring.Extremely
Distance of the time by adjustment link to be adjusted for example away from the first or second measuring cell 13,14 (for example takes off yarn roller 8 or pressure yarn
Distance of the servo motor of roller 9,9 ' away from the second measuring cell 13) calculated with reference to the speed of production of copolymer of fiber suede 20.For adjustment
Link 18,19,19 ', 19 ", 19 " ' ... the value of adjustment be empirical value, it can be for different fiber types
In different and input regulator 15.Similarly, the characterisitic family of adjuster be based on for the material of copolymer of fiber suede, MD/CD ratios,
Thickness and the empirical value so as to the weight per unit area for copolymer of fiber suede.These values store the characterisitic family in adjuster 15
In and therefore controlled at regulation parameter (13a, 14a) deviation control parameter (16,17) rotating speed or roller gap change it is big
It is small.Especially (wherein directly change weight per unit area) when roller gap is changed, can be directly realized by for unit area
