Description
Technical field
The present invention relates to a kind of method for being used to controllably start loom and tapping machine, wherein loom is by means of main driving
Mechanism is driven, and tapping machine driven by means of the auxiliary drive mechanism of electric notor formula.
Background technology
Such loom and tapping machine are known.Tapping machine has single drive mechanism wherein, the drive mechanism
Central drive shaft be connected with electric notor, the motion of opening device is left by central drive shaft guiding.The tapping machine
It is such tapping machine, opening device can be disengaged with the motion of the drive shaft in center and coupled wherein, e.g. St ubli companies
Structure type be 2881 dobbies or the structure types of St ubli companies be that the structure types of LX or Bonas companies is SI
Jacquard.
Loom drive shaft (in addition motion (woven reed (Webblatt), if be possible to machinery lead latitude element) by the drive
Moving axis guiding leave) in terms of it with least one directly drive the drive shaft, be generally likewise constructed to the execution of motor
Device is connected.Such direct drive mechanism be in its mechanical structure it is very simple, it is almost non-maintaining and can be very
Accurately adjust.
In addition the drive mechanism of loom and tapping machine (is referred to as converting below by means of common DC voltage intermediate circuit
Device intermediate circuit) it is connected, so that they can construct energy stream each other.
It is for one in the shortcoming of the above-mentioned direct drive mechanism of loom, for the high dynamic required by loom
Starting for necessary to larger peak power directly must be provided by actuator.The peak power can be substantially straight
Electric supply system was connected to supply.Such power peak can be horizontal in stable supply system and suitable transfer pipeline
Cause strong voltage disturbance in the case of section, it proceeds to the intermediate circuit voltage of the converter for direct drive mechanism
In and cause to interrupt caused by the upset of loom start in this place.When loom is driven at weaker supply system, this is asked
Topic also significantly intensifies.This is this with the transfer increased of the textile manufacturing in developing country and newly industrializing country
Situation is increasingly common.More unfavourably also there is this relation, i.e. when due to rated voltage level and/or electric supply system
Type when to cause pre- transformer (Vortrafo) be required, the pre- transformer is by its additional direct impedance from waiting to start
The angle of loom set out and network is become weaker.
If to the loom being provided on the first beating (Blattanschlag) rotating speed (referred to hereinafter as working speed)
Starting is no longer possible for these reasons, then known countermeasure is, makes rotating speed reduction.That is, for the first beating
Working speed then more or less significantly in being provided under the running speed of object in itself.But, this can
Cause start position (starting flag) and unacceptable mass loss in fabric (Webware).Running speed it is usual
Reduction be equally unacceptable solution because the completion of object can correspondingly last much longer, this is by fabric
(Weberei) rentability is placed in risk.
The U1 of file DE 200 21 049 are compared to immediate prior art for the separation for loom and tapping machine
There is such possibility, i.e. be so designed that the known from the C1 of file DE 100 53 079 of tapping machine for drive mechanism
Preferential starting, that is, cause its pass through its kinetic energy aid in loom subsequent starting process.This tapping machine is accelerated to
The rotating speed on working speed that the terminal of loom start should reach.During final loom start, tapping machine by making again
Move and support to provide kinetic energy (that is during its start-up period) for its starting.
The U of file DE 200 21 049 are (especially because it focuses on the common motor utilized for loom and tapping machine
The drive mechanism solution of formula element) propose, the braking procedure of tapping machine with the beginning of loom start used and
Equably carried out (in practice) during the starting process.
However, it has proven that such feedback (R ü ckeinspeizung) is not optimal, because being knitted in this tapping machine
Machine is started will feed back the more energy being in a ratio of needed for loom when starting.In the drive mechanism for loom and tapping machine
In common converter intermediate circuit, voltage level then can consumingly be raised and energy must be converted into brake drag
Heat and loss can be produced for process.
The content of the invention
Therefore the task of the present invention is, by the improvement of the feedback energy on the power to tapping machine make full use of come
Reduce loom maximum power requirement, wherein process safety should by maintain the voltage limit in converter intermediate circuit come
Ensure.It should also be as receiving the knocking over (Abschlag) in the starting dynamics of loom.
The task is solved by the feature of independent patent claim in the method according to the invention.
On the one hand the method for being used to starting according to the present invention, which includes starting to tapping machine, predetermined crosses rotating speed (below
Referred to as step 1) and on the other hand include the rotating speed reduction of so adjustment tapping machine, that is, cause tapping machine rotating speed trend it is oblique
Degree is in the section later of start-up period compared to more negative in section a little earlier (being referred to as step 2 below).
Steps noted above 1 is that crossing rotating speed, (tapping machine is accelerated to this in being beaten up relative to working speed first
Cross rotating speed) it is scheduled or is accurately defined in its value and/or in its limes superiors.Ground is particularly preferred, rotating speed is crossed automatically extremely
Still calculated less according to machine data, preferably also according to process data.Thus ground in more detail in content further below
Study carefully.
Step 2 (advantageously surrounds the starting from t2 to t3 of loom completely for time range t1 to t3 on its time
Journey can also decline together with the starting process) trend of non-ramped shaped is provided with for the rotating speed of tapping machine, i.e., with step
Rotating speed of crossing in rapid 1 starts non-constant gradient.Gradient is moved towards in this way, causing the slightly slow time section in starting process
In, energy backflow is compared to bigger in time section a little earlier.It means that the braking of tapping machine do not equalize (ramp type
Ground) carried out by loom start, but in the slightly slow section of start-up period and preferably relative to the end of loom start
Point is strengthened.Thus the actual energy requirement of loom is considered in the case where considering thermal loss and other losses.
When being also most strong in terms of loom of the demand in starting, according to the feedback of energy of the present invention or power therefore
Demand is realized adaptively (that is with especially strong degree).
Temporal average value of the gradient that advantageously rotating speed of tapping machine is moved towards between time point t2 and time point t'
So born not as good as the temporal average value between time point t' and t3.The gradient moved towards in the rotating speed of this tapping machine is started
The terminal in stage is compared to more negative in the period a little earlier of start-up period.It means that the destination county in start-up period is compared
More energy feed back to loom from tapping machine at the beginning of start-up period.
Similar favourable rotating speed trend is arranged to, and the gradient of the rotating speed trend of tapping machine is in time point t2 and time point t'
Between temporal average value compared between time point t' and t3 temporal average value have lower absolute value.
With being particularly preferred, the gradient of the rotating speed trend of tapping machine is in the whole of start-up period in the terminal of start-up period
It is most negative in period.In the design, therefore energy back is maximum in the destination county (in time point t3) of loom start
's.
If the gradient of the rotating speed trend of tapping machine (which time point being slower according to) from time point t1 or t2 is
The function strictly monotonously declined, the energy from tapping machine to loom, which is flowed into, constantly to be lifted, and this is relatively precisely demonstrated by
The actual energy requirement of loom.
The rotating speed trend for being used for the loom of starting in a preferred embodiment is not also preset to ramp type, but has
The gradient of decline in whole starting process (between time point t2 and t3) or at least towards its terminal.Therefore power disappears
Consumption is averaged, that is to say, that power peak is smaller formed in the terminal of loom start, and energy is simplified from there through tapping machine
On rise dynamic auxiliary (Starthilfe).Herein it should be noted that the rotating speed of loom currently can be regarded as such value, it is calculated
On moment of inertia (it is then defined) average from its kinetic energy and energy draw.
As listed above, the rotating speed of crossing referred to of tapping machine is applying number of machines preferably by means of arithmetic element
Calculated in the case of.It is also preferred that tapping machine rotating speed move towards for the whole start-up period of loom by
Calculated in arithmetic element in the case of application machine data, the rotating speed trend of wherein tapping machine has herein been preferably oriented at
In the calculating of dynamic loom at desired power demand.
The machine data referred to is preferably such machine data, and it partly or wholly considers following group：Open
On the energy of the moment of inertia of mouthful machine and/or loom, tapping machine and/or loom average moment of inertia, network it is related and supply
To the characteristic of related data such as common exchanger intermediate circuit, tapping machine and loom drive mechanism it is technical
Characteristic, the peak power etc. of supply.
Not only machine data but also process data in order to improve accuracy be preferably applied in calculate tapping machine cross rotating speed
And in other rotating speed trend.The process data preferably at least partly applied is based preferably on calculating or estimation
Loom loses and advantageously equally based on tapping machine loss.It is based preferably on the duration of the start-up period referred to of loom
Such data fall within the process data.
Two steps 1 and 2 are more accurately explained below.
Tapping machine is calculated in terms of step 1 crosses rotating speed.Loom is at least preferably at least considered as machine data and is opened
Average moment of inertia on the energy of mouth machine.Here, the average moment of inertia on energy is the used of the flywheel mass of consideration
Property torque, its (using and working machine (loom or tapping machine) identical running speed rotate) have it is identical with related working machine
Kinetic energy.
By the relation of moment of inertia average on the two energy of loom and tapping machine, the relation of two kinetic energy is certainly
Start and be also secured in identical size.Now it is possible that tapping machine to be accelerated to so high rotating speed excessively (in calculating)
On, that is, cause its it is subsequent brake again in the case of provide so many energy so that starting of the energy for loom
Enough.To the sample calculation of this system for being used for free of losses：
It is applicable for loom：
Average moment of inertia on energy：
Working speed for startup：
Thus kinetic energy is drawn：
It is applicable for tapping machine：
Average moment of inertia on energy：
Working speed for startup：
Thus following kinetic energy：。
In order to which the energy requirement of loom is completely covered, tapping machine must have (7896+ when loom start starts
3948) J=11844J kinetic energy, this corresponds to 735min-1Rotating speed.But, so big size of tapping machine drive mechanism from
Cost angle is not desirable, so that above-mentioned mode (energy requirement for being used for loom start is all taken from tapping machine)
It is unpractical.But sample calculation is shown, average moment of inertia is to be used to determine tapping machine in loom start on energy
The speed curves (Drehzahlprofil) or the significant numerical value of tracks of period.
Another important numerical value is the cyberrelationship and the relation between supply and demand having already mentioned above.Preferably especially consider to use herein
In the characteristic value of the supply of loom and the common exchanger intermediate circuit of tapping machine.
In addition advantageously consider that the assembling of supply is used for the peak power of the duration of loom start, such as twice of volume
Determine power.It is equally important that pre- transformer is for example because whether dedicated network (such as IT networkings) is applied in fabric.Herein
The power and short-circuit voltage or internal driving of pre- transformer are important.
The cyberrelationship and the relation between supply and demand enumerated in above-mentioned scope should be associated with machine data, equally for example loom and
The technical characteristic of the drive mechanism of tapping machine, the maximum current and/or actuator or motor of such as adjuster are most
Big rotating torque.
The desired loss of loom treating during starting process first is important in terms of process data.This can for example from
The current needs that estimation or (when loom is run in advance) are equalized by it in the temperature of transmission oil are considering to use
If the life-span rethinks that oil temperature and being possible to considers to estimate in the case of new running speed.Tapping machine includes opening device
The loss of (bar, flat bar) is Preferably also taken into account.
Started from the whole energy requirement (summation of the balance of kinetic energy and loss in working speed) of loom
Average power and peak power can be calculated in journey and duration of starting.It can estimate again from cyberrelationship and the relation between supply and demand
Meter, for the power (peak power first) by tapping machine rise dynamic auxiliary whether and which kind of degree to be necessary with or can
Use.
Corresponding to the degree according to a preferred form of implementation by means of the average moment of inertia on the energy of tapping machine
It is determined that when loom start starts, tapping machine crosses rotating speed, so that can be provided in the case of to braking again on working speed needs
The energy or power wanted.If this occurs in the case where adopting the braking again of the average ramped shaped of tapping machine with the time, with
The approach obtains minimum possible values, and the value has allowed for the rotating speed excessively for energy back of tapping machine.
Therefore it can be produced for the purpose of the starting support of loom separately through using step 1 by means of approach identified above
Mathematically clear and definite preset value for the rotary speed property of tapping machine.But found out within the scope of this invention, such as above
Through as implementation, same shape, that is ramp shaped braking of the tapping machine during loom start is not optimal
's.It is that tapping machine has been fed back when loom start starts than much more energy required for loom in this case.Due to
The high voltage not allowed in exchanger intermediate circuit, this very quickly can cause to disturb (especially in passive network supply)
Start and interrupt caused by disorderly.
Solved according to the problem of the invention by applying step 2.Risen by tapping machine rotating speed during loom start
More negative gradient in the slightly slow section in dynamic stage, energy back little or no first into exchanger intermediate circuit, with
Increased time and the energy that therefore increased power demand or energy requirement are fed back for loom are correspondingly more.
Before steps noted above 1 and 2 is performed preferably in terms of the arithmetic element referred to according to machine data or
If being possible to be determined according to process data, by the energy of tapping machine starting support whether be entirely in the urgent need to.When
When being, operator advantageously either requires activation or permits starting support or thus recognize, it automatically swashs
It is living.In the case of the latter but it will be appreciated that operator provides and do not activated the possibility of dynamic auxiliary.

Fig. 3 show with it is similar in t1 in fig. 2<Schematical speed versus time-chart in the case of t2, but carry
The local maximum of the rotating speed of tapping machine, and
Fig. 4 is shown in t1>Schematical speed versus time-chart in the case of t2.
Embodiment
Fig. 1 shows computational methods, and the computational methods are the following is starting point, i.e., at each time point of loom start
The power demand of loom is aided in by share, wherein share relatively sees holding identical (such as 40%).Loom start should so enter
OK, i.e. so that the rotating speed ramped shaped calculated by the average moment of inertia of kinetic energy and energy brought up to the time on working speed.
Here, then the expected power demand with the share for keeping percentage constant of loom is capped, it is possible to, time point
T2 (that is starting time point of loom) is not in before time point t1, and tapping machine has reached it at time point t1
Predetermined crosses rotating speed.
In calculation procedure 1A, the power demand maximum first of loom is determined by machine data and process data 1A'.
Consider the average moment of inertia on the working speed and energy of loom in this example as machine data.It is used as process data
The loss to be expected of introduction loom or loss torque and the starting expressed as time or the angular range streaked continue
Time.
Loom is suitably calculated first in start-up course destination county, the kinetic energy i.e. in the case of working speed.The energy
To draw the moment of accelerating mechanically worked by way of dividing ground the angular range streaked.The loss torque of expectation is in work
It is added into the case of rotating speed wherein, the oil temperature that the loss torque is depended primarily in transmission mechanism.What is so occurred is total
Torque is multiplied with working speed provides the maximum demand power of loom.
The maximum demand power relatively provides such machine data in terms of it now, and the machine data shows
The feature of cyberrelationship and the relation between supply and demand；It include possible pre- transformer characteristic (rated power, short-circuit voltage or
Internal impedance) and feed unit for converter intermediate circuit characteristic (passive or active network supply, if having
Possible boost chopper function, peak power).Opposed is estimation.Which for example store in the table, in peak power
Which voltage disturbance involved pre- transformer or involved feed unit can expect in situation.Then, if in conversion
Total voltage interference so to be expected in device intermediate circuit is so strong, so that the voltage requirements at motor clamper
It is no longer able to low voltage monitoring that is capped and/or triggering converter intermediate circuit and causes starting to be interrupted, so in tapping machine side
Face must correspondingly supply additional energy or power.This treats the power fraction that is put into by tapping machine as calculation procedure 1A value
1a'(demands) provide.
Desirably, simultaneously or immediately calculation procedure 1B is implemented parallel to calculation procedure 1A, wherein opening driving
The known torque capacity of mechanism is multiplied with its working speed.Obtain the peak power of opening drive mechanism.If before being possible to
Also loss torque is subtracted from torque capacity.Be open drive mechanism such calculating peak power as calculation procedure 1B value
1b'(possibilities) provide.
Compare 1a'(demands first in calculation procedure 2) and 1b'(possibilities).If demand is more than possibility, foregoing
The problem of type, can not be excluded when starting onto intentional working speed.Therefore reaction is triggered in step 2B.This can
It is present in the alarm signal at operator, if being possible to related to requirement, recalls lower working speed and with test
Mode starts machine, referring to path 2b'.In this way, the actual observation of converter intermediate circuit can be passed through by step 1A estimation
Behavior is corrected.Another possibility is that, under the corresponding instruction circular at operator, automatically reduce working speed.
If here, then involved machine start can also be used for confirming and be possible to correct the hypothesis from step 1A.Reduce
Working speed should be calculated so herein, i.e. so that demand 1a' and possibility 1b' is entirely identical for the working speed
High.
(mathematically being expressed with Min (1a', 1b')) less one in two values 1a', 1b' is delivered to calculating as 2c'
Step 3 place.By the way that the half of the peak power is multiplied with the time needed for loom start, obtain waiting to throw in terms of tapping machine
The energy entered, the tapping machine must then maintain the energy at the time point t2 of loom start.From the additional energy of tapping machine
Rotational speed omega was calculated in amount, working speed and the average moment of inertia of energyÜ,FBM, tapping machine must time point t2 (compared to
Working speed) there is this to cross rotational speed omegaÜ,FBM.(in order to understand also referring to the system for free of losses in more foregoing
The computing example enumerated).
Loom in starting in the case of power demand developed in the mode that rotating speed is proportional and the time is proportional, therewith
Correspondingly (according to the above-mentioned agreement for this method), power to be put into terms of tapping machine equally develops (until most Zhongdao
Value 2c').By the fact and for ωÜ,FBM(t2) known value can be straight for each arbitrary time point t from now on
To at time point t3 loom start end calculate for tapping machine rotating speed value ωFBM(t).Pass through product in time
Get angle and move towards φFBM(t).Associatedly, as driven adjuster to need preset value, such as in region [t2 ...
T3] in equidistant time point for formed carry ωFBMOr φ (t)FBM(t) value of the ordinate value of subordinate is to (grid
Point), software routines (Software-Routine) (if being possible in adjuster is driven in itself) generation therefrom is corresponded to
The expression mathematically of electric cam (Kurvenscheibe).The forwarding for calculating the data needed of loom is sharp in Fig. 1
Marked with 1a''.
Another favourable computational methods are to apply multinomial, and its coefficient is determined into, are thus risen in the desired manner for loom
The rotating speed trend or angle trend of the pre-qualified tapping machine of dynamic scope.
Three exemplary trends of the rotating speed of tapping machine (FBM) and loom (WM) are presented corresponding to the present invention in fig. 2
It is used as the function of time.At time point t0, start tapping machine and until time point t1 advance to it is predetermined, especially calculate
Mistake rotational speed omegaÜ,FBMUpper (see above).Loom is started at time point t2 and is reaching time point t3's from time point t2
In start-up period, working speed ω is started toarb.Energy feeds back to loom with limiting from tapping machine during the start-up period, its
In the possible computational methods relevant with this have been envisaged above.
For the present invention importantly, tapping machine rotating speed trend gradient loom start-up period it is slightly slow
Compared to more negative in section a little earlier in section (it is between time point t2 and t3).Slightly slow section is not forcibly adjacent herein
The section being connected at time point t3 and/or a little earlier be not contiguous to forcibly time point t2 (or t1, when t1 is later than t2, ginseng
See Fig. 4) place；Can also be compared to each other on the contrary periods of the time point t2 (or t1, when t1 is later than t2) between t3 with
Interior gradient trend.
It can be learnt from Fig. 2, the utilization solid line of the rotating speed trend of tapping machine (referred to here as FBM') is in this embodiment
Existing gradient even about the whole period of start-up period is most negative in the terminal of start-up period, that is to say, that curve when
Between there is at point t3 most negative slope (Steigung) in scope between t2 and t3.Preferably the rotating speed of tapping machine is moved towards
Gradient between time point t2 and the time point t' exemplarily marked in fig. 2 not as good as between time point t' and t3 when
Between on average value so bear.
It is also possible that the morning that the rotating speed of tapping machine is moved towards in start-up period between time point t2 and t3 is interim or even short
Temporarily there is positive gradient, that is to say, that positive slope, followed by gradient and then again change are negative.
The rotating speed presented with solid line of loom (referred to here as WM') is moved towards
It is existing, as this assumes in above-mentioned computational methods.Depict for the alternative of loom (referred to here as WM'') dotted line
Rotating speed trend, there is the positive gradient successively decreased during startup of the rotating speed between time point t2 and t3 wherein.Such
Power consumption is average than in the case of linear startup in the case of trend, because power peak is in the terminal of loom start
Less formed.The exemplarily corresponding rotating speed trend of tapping machine (referred to here as FBM'') is equally presented with dotted line.It is more flat
Smooth trend compared to rotating speed move towards FBM'(especially towards loom start-up period terminal, that is time point t3) it is corresponding
More flat herein in loom moves towards WM'' because energy back the start-up period of loom terminal for ramped shaped liter
It is less than the rotating speed WM' of loom for high situation about previously discussing.
In addition the 3rd modification in fig. 2 is drawn into using chain-dotted line.The rotating speed trend of loom (referred to here as WM''')
With S-shaped shape, this S-shaped shape also occurs again in tapping machine (referred to here as FBM''') rotating speed trend.From tapping machine to
Energy back (being moved towards according to the more flat rotating speed of the difference and then after time point t2) at loom is in the rotating speed of loom
Rise most drastically during be king-sized.Towards the start-up period of loom two rotating speeds of terminal trend (FBM''' and
WM''') planarize again.
Situation about being described above the local maximum for presenting the rotating speed of tapping machine in figure 3.It must check respectively for, should
Whether local maximum is on the reliable maximum (top) speed in tapping machine.
Such case is depicted in Fig. 4, i.e. time point t1 is slower compared to time point t2.Because (as beginning described in that
Sample) from demand angle, loom is not acquired an advantage at the beginning of start-up period from the support in terms of tapping machine, in opening
Machine is before time point t1 reaches its rotating speed excessively calculated, and (in time point t2) can start loom.Importantly, the opening
And then machine is ready to transfer energy at loom in the time interval from t1 to t3.
The manipulation of the main driving mechanism of loom and the electron assistant drive mechanism of tapping machine is undertaken by controller, the controller
It is prior art and is not therefore more fully described herein.Calculations set forth above utilizes the fortune being connected with the controller referred to
Unit is calculated to perform.
