Description
Technical field
The present invention relates to a kind of method and a kind of corresponding processing machine, a kind of corresponding computer programs and a kind of corresponding computer programs product that axle is proofreaied and correct that be used on processing machine, carrying out.
Although following main with reference to printing machine, the present invention is not limited to this, relates to or rather article breadth all types of processing machines of processing of material web in other words.But the present invention especially can use on such as newspaper printing press, star print printing machine, intaglio press, in-line arrangement flexible printing machine, packages printing machine or printing machine for securities using at printing machine.The article breadth can be made of with form of film etc. paper, cloth, cardboard, plastics, metal, rubber.
Background technology
On processing machine especially printing machine, the article breadth along driven axle (breadth conveying axis) such as nippin rolIer or feed rolls and non-driven axial ratio such as slewing rollers, guide roller, dryer roll or chill roll motion.The article breadth is processed by means of most of same driven processing axles simultaneously, such as printing, stamping-out, cutting, fold or the like.
The web tension of article breadth influences by so-called clamped position, and described clamped position clamps described article breadth with the form that friction connects, form fit connects or power transmission connects.Normally driven conveying unit of said clamped position or processing unit.On intaglio press, clamped position is made of the printing unit usually, and the unit that frictional fit connects in this printing unit is present between driven printing cylinder, top press roll and the material web.Described article breadth can be divided into breadth tensioning section, and wherein, breadth tensioning section is subjected to the gauge of two clamped positions.Within breadth tensioning section, can arrange other driven axle and/or non-driven axle.
When quickening in other words the deboost phase (rotation speed change), must consume dynamic power, be used to make described non-driven acceleration to brake in other words.In this process, must apply the moment of inertia and the friction of non-driven roller.
Usually when process velocity (regulating the speed) is low, machine is adjusted, be used for maculature is reduced to bottom line.Acceleration by subsequently alignment and web tension deviation occur until reaching speed of production, must compensate described alignment and web tension deviation at this.
Open, the angular adjustment by means of the printing unit in boost phase reacts on the variable elongation that causes by quickening, and wherein comes the printing unit that successively accompanies is controlled in advance with the amplitude of the angular deflection of rising.
Can obtain described angular deflection by the enforcement of measuring driving (Messfahrt).But the shortcoming in this existence is, produces maculature and must analyze viewed registration error when measuring driving.Manual analyzing is easy to generate error, and analyzes because essential sensor element is expensive automatically.In addition, the enforcement of measuring driving relatively expends time in, because must correspondingly be that the different boost phase that is occurred implements to measure driving.
In addition, can be by calculating to determine pre-controlling value, because these pre-controlling values are proportional about the inverse and the acceleration of described non-driven inertia, elastic modelling quantity.Open, can manually pre-determine described inertia and elastic modelling quantity by the user.
This shortcoming by prior art solutions is input error may occur and always accurately not know necessary data on the other hand on the one hand when pre-determining data by the user, especially as elastic modelling quantity.
Summary of the invention
Therefore, task of the present invention is that a kind of the acceleration or improved axle bearing calibration during the deboost phase is described.
This task by a kind of by the described method that axle proofreaies and correct, a kind of that is used for of claim 1 by the described processing machine of claim 8, a kind of by the described computer program of claim 14 and a kind ofly be resolved by the described computer program of claim 15.Favourable improvement project is the theme of dependent claims and following explanation.
By especially carrying out web tension and/or alignment adjustment or adjusting by the method that is used for the axle correction of the present invention, considering in the process of the rotation speed change of the clamped position of gauge breadth tensioning section in the method under the situation of the elastic modelling quantity of material of described article breadth and at least one non-driven the moment of inertia that in described breadth tensioning section, exists that to gauge the clamped position of described breadth tensioning section and/or the processing axle that exists control in advance in this breadth tensioning section, wherein automatically determining the elastic modelling quantity of the material of described article breadth.The scheme of elastic modelling quantity of material that is used for determining the article breadth is open such as obtaining at DE 10 2,005 056 802 A1.
By proofread and correct especially web tension adjustment and/or alignment adjustment in breadth tensioning section, can reduce the shortcoming of prior art at the axle that is undertaken by the present invention during elastic modelling quantity under the situation of the elastic modelling quantity of the material of considering described article breadth and the non-driven the moment of inertia that at least one exists at the material of determining described article breadth automatically.
Advantageously, needn't know the material data that depends on production by calling of early stage production in other words in the material data of producing by input dependence, because can automatically try to achieve described data independently in other words.Can when machine down, determine to quicken the adjusting of compensation, wherein not produce maculature.
Compared with prior art be one by pre-control of the present invention and significantly improve,, and needn't react the error that has occurred because the pre-control of the predictability that the error that can expect is carried out can be provided now.By regulate the correction on the meaning of adjusting in other words in web tension, minimizing is quickened or the web tension of deboost phase changes, and this is directly obtaining embodiment aspect the minimizing of waste product.Change by littler web tension, reduce register partial difference equally, described register partial difference is proofreaied and correct by axle same explanation, on the meaning that the alignment adjustment is controlled in other words and is further reduced.Because additional pre-control can be formulated and more effectively be adjusted strategy, because can produce bigger influence to the article breadth.If reached stable status such as printing machine, so vertically register partial difference can be compensated quickly by means of the adjustment strategy of static state, and described pre-control is included in the adjustment strategy of described static state.If machine is in the dynamic transition stage such as the variation of web speed in the variation of the rated value by web tension or the machine, so described pre-control has just realized dynamic faster alignment adjustment.
By by measure of the present invention, when alignment adjusting and/or web tension adjusting, realized the more strong decoupling of described article breadth and reduced the described non-driven the moment of inertia and the influence of moment of friction.Print error static state between the unit and dynamic in other words at each processing unit and obtained reduction.In addition, can compensate registration error quickly.Reduced quicken or the deboost phase to the reaction of web tension, this especially makes and quickens more dynamically in other words faster in other words that braking procedure becomes possibility.Obviously reduced waste product maculature in other words in a word, this makes production cost reduce in addition.
Advantageously, all relevant axles of described breadth tensioning section are controlled in advance.Especially for adjusting the web tension of regulating in other words in the breadth tensioning section clamped position of described gauge breadth tensioning section is controlled in advance, and controlled in advance for the alignment of the processing axle within breadth tensioning section being adjusted the clamped position of regulating in other words described processing axle and/or described gauge breadth tensioning section.

Advantageously, under the situation of considering all non-driven corresponding (effectively) the moment of inertias that in breadth tensioning section, exist, control in advance.Can further improve the quality of pre-control thus.
Preferably all non-driven corresponding the moment of inertias that exist in this breadth tensioning section are concentrated to being total the moment of inertia of this breadth tensioning section consideration.This is can simply implement a but still measure that good result is provided." center of gravity formation " by hypothesis can only take in total the moment of inertia.This total the moment of inertia is such as trying to achieve with one of aforesaid way (measuring driving etc.).
Particularly advantageously, the pre-controlling value of pre-control that is used for described clamped position and/or processing axle is carried out static state and/or dynamic cascading (kaskadieren) in order to take off coupling with the clamped position and/or the processing axle of adjacent breadth tensioning section.Can with different factors such as with that put upside down, proportional, carry out cascade by mode share or dynamic etc., be used for making adjacent breadth tensioning section and take off coupling in the pre-control of relevant breadth tensioning section.
Also advantageously, additionally under the situation of the rotation speed change of considering described clamped position, control in advance.Because the error that can expect is proportional with the positive acceleration or the negative acceleration of the just described axle of the rotation speed change that is occurred, so advantageously when pre-control, this acceleration is taken in equally.Acceleration ratio is as determining such as the secondary differentiate of position sensor numerical value or a differentiate of velocity sensor numerical value by the differentiate to specific sensor values.For position measurement or tachometric survey, such as can the information that be imprinted on the article breadth being scanned such as mark, punching etc.Can determine by means of acceleration transducer equally.In addition, can consider to be used for web tension and to adjust the computing unit that alignment is in other words adjusted, wherein such as the nominal position that can transmit machine-guiding position, normal speed, rated acceleration, specified impact (Soll-Ruck), physical location, actual speed, actual acceleration or actual impact (Ist-Ruck) such as the numerical value of machine controlling organization being transferred to by means of field bus communication.Also can adjust the computing unit that alignment in other words adjusts and transmit the binary signal that display speed changes to being used for web tension, and can adjust the computing unit of alignment adjustment in other words and know impact given in advance regularly acceleration value in other words being used for web tension from the machine controlling organization.Can estimate acceleration such as driving moment by means of other process variable at last.

The specific embodiment
Fig. 1 show by of the present invention be configured to printing machine, preferred embodiment a kind of with 100 processing machines of representing generally.Printing material flows to this machine such as paper 101 by drawing in unit 110.Clamped position guiding and the printing and by pull out unit 115 once again transported out of described paper 101 by being configured to print unit 111,112,113,114.Describedly draw in unit, pull out unit and printing unit 110 to 115 and can locate ground, especially can carry out cylinder and proofread and correct the ground of angle correct in other words and arrange.Described printing unit 111 to 114 is in describedly to be drawn in unit 110 and pulls out in the zone of the adjustment web tension between the unit 115.
Described printing unit 111 to 114 has printing cylinder 111 ' to 114 ' respectively, top press roll 111 " to 114 " abut against described printing cylinder 111 ' to 114 ' with stronger pressure respectively.Can be individually and drive described printing cylinder 111 ' to 114 ' independently at this.Drive unit 111 under this has schematically illustrated " ' to 114 " '.Described top press roll 111 " to 114 " be configured to free to rotate.Described draw in unit and pull out unit 110 115 have the reverse cylinder that paper 101 in two delivery respectively in other words.Described draw in unit and pull out unit 110 in other words 115 also can be individually by drive unit 110 " ' in other words 115 " ' drive.The described unit of drawing in correspondingly forms the unit that is connected with the friction connected mode with the paper 101 that passes through continuously with pulling out unit 110,115 and printing unit 111 to 114.Describedly draw in unit 110, pull out unit 115 and printing unit 111 to 114 is represented clamped position respectively.
In being in the breadth section of each printing between unit 111 to 114, described paper 101 by explain in detail, come delivery with 102 rollers of representing.For the purpose of coming into plain view, not every roller all is furnished with Reference numeral 102.Especially can relate to deflecting roller, drying device, clipping device or the like at this.
Chill roll is passed through in guiding after the print steps of described breadth 101 in one of printing unit 111 to 114.In the breadth section that is between the first printing unit 111 and the second printing unit 112, arranged chill roll 121 for this reason, in the section that is between the second printing unit 112 and the 3rd printing unit 113, arranged chill roll 122, in the section that is between the 3rd printing unit 113 and the 4th printing unit 114, arrange chill roll 123, and in being in the 4th printing unit 114 and described section of pulling out between the unit 115, arranged the 4th chill roll 124.
Described chill roll 121 to 124 and described roller 102 have the effective moment of inertia that the boost phase to printing machine has a negative impact respectively.A kind of preferred embodiment shown according to printing machine controlled all clamped positions under the situation of the effective moment of inertia of the elastic modelling quantity of the material of considering described article breadth and described chill roll 121 to 124 and roller 102 in boost phase in advance.Described effective moment of inertia is in advance by means of measuring driving (Messfahrt) and analysis subsequently disposable trying to achieve usually.Automatically determine described elastic modelling quantity.The pre-control that enforcement takes in described elastic modelling quantity, effective moment of inertia and acceleration in boost phase.At this, such as can (differential is delayed element (differenzierend by means of the DT1-element
Glied)) implement pre-control with dynamic timing element, wherein select T1 pro rata with breadth length/machine speed.Pre-control can comprise the angle value of addition.As a result of, as by means of illustrated in fig. 4, in the desired section of article breadth, obtain the change curve of approximately constant of web tension and the register partial difference that is therefrom almost disappeared.
Determine that to being used for the scheme of elastic modelling quantity describes by means of Fig. 1 below.At first such as fixing described draw in unit 110 and make ensuing printing unit 111 move one can be given in advance angle delta
Preferably can in the adjustment of position, regulate by means of angular movement.Described angular movement can be carried out with little step size increments formula at this, is used for preventing that material from excessively extending towards plastic region.Can in the speed adjustment, regulate equally by means of angular movement.Also can in the moment adjustment, regulate by means of angular movement.In addition, preferably can in position adjustment or speed adjustment, regulate by simultaneously driving moment being limited by angular movement.At this advantageously, opposite with the moment adjustment, described angular movement-speed can be restricted and can move into more reposefully thus in the moment restriction.
Described elastic modulus E can be used formula E=(Δ Fl
o)/(A Δ l) calculate, wherein Δ F is the power that is consumed, l
oBe original length, A is the area of material web, and Δ l is resulting length variations.
Described power Δ F can measure by means of being arranged in the dynamometer (not shown) that is in the described breadth section of drawing between the unit 110 and the first printing unit 111.Described length l
oAnd be known or can measure in simple mode in the area A of drawing in unit 110 and the article breadth of first printing between the unit 111.At last, described length variations Δ l can be as the angular adjustment Δ
Determine with the product of the radius of roller platen or determine by means of position sensor (such as motor sensor).Scheme as an alternative also can be by predesignating web tension by means of determining tension variation in the power of drawing in unit and/or pulling out the vertical vibration roller in the unit.As long as have the vertical vibration roller in the unit drawing in unit and/or pull out, that just can utilize preestablishing of vertical vibration roller pressure that power is applied in the described article breadth.This power that is applied in then produces web tension.Equally can be by means of the power of the top press roll of not depressing fully preestablish web tension given in advance.If depress described top press roll, so also can apply web tension by curling round the roll.Utilize resulting data can determine to depend on the constant k=EA of production at last.
Scheme is used as the power parameter such as the measurement that can replace (existing) dynamometer with the motor torque that is consumed as an alternative.In this case, should the friction effect outside the breadth tension section be taken on the one hand, and should the pulling force outside the breadth tension section be taken on the other hand, because they correspondingly influence the motor torque that is consumed.Described pulling force can be ignored, if material web is outside two clamped positions that this material web is clamped in measuring process, just almost completely lax outside the drawn-back device 110 and second printing equipment 111 in embodiment chosen.Otherwise the web tension before measuring section after in other words can be distorted the web tension of trying to achieve from measured motor torque.
Next equally exemplarily the scheme that is used for definite inertia mass is showed now.As long as not knowing the described in other words inertia mass of described inertia mass leaves in the acceleration compensation (Beschleunigungskompensation) regularly as constant, so described inertia mass can be tried to achieve by means of measuring driving when the elastic modelling quantity of described article breadth is known, wherein proposes two kinds of flexible programs.In boost phase, can change on the one hand such as the web tension of determining by means of dynamometer to be produced.When elastic modelling quantity is known, calculate effective inertia mass by means of this measurement then according to web tension variation and machine acceleration.In boost phase, can determine the registration error that produced on the other hand.When elastic modelling quantity is known, can determine that the web tension that is produced changes according to described registration error.Can determine described effective inertia mass again with the machine acceleration.
Fig. 2 has drawn the change curve of web tension under dynamic situation in the prior art about the time in chart 10, two web tension change curves 13 and 14 have been shown in this chart 10.In chart 10, drawing web tension about the time t on x-axle 11 on the y-axle 12.Fig. 2 shows the web tension change curve that is under the dynamic situation, under this dynamic situation the roller that participates in is quickened.
Two web tension change curves 13 and 14 corresponding to different breadth tensioning sub-segments have been shown in chart 10.At breadth tensioning section of this research, this breadth tensioning section is divided into two breadth tensioning sub-segments that are adjacent to each other by non-driven axle, the roller that is cooled in the embodiment that is drawn.Clamped position (driven axle) is arranged respectively on the end of described breadth tensioning section, is driven roller platen in the embodiment that is drawn.With reference to Fig. 1, such as a kind of as can be seen described breadth tensioning section between printing unit 112 and printing unit 113, this breadth tensioning section roller 122 that is cooled is divided into two breadth tensioning sub-segments.To at length remark additionally at this, diagram by Fig. 1 shows by printing machine of the present invention, in this printing machine for pre-control not only consider described article breadth material elastic modelling quantity and also consider the effective the moment of inertia of described chill roll 122, in contrast, Fig. 2 then relates to a kind of printing machine, and described pre-control is not set in this printing machine.
Following the trend of article breadth, web tension change curve 14 pairing breadth tensioning sub-segments are between clamped position and the non-driven axle, and and then web tension change curve 13 pairing breadth tensioning sub-segments directly are between described non-driven axle and the ensuing clamped position in article breadth trend.
As can from as described in find out that described web tension has littler numerical value than being in the zone between described non-driven and the ensuing clamped position usually the chart 10 in the zone that is between clamped position and the ensuing non-driven axle.
In the boost phase 15 of pressing Fig. 2, dynamic power 16 poor corresponding between described web tension change curve 13 and 14, this power 16 is used to drive described non-driven roller.In the embodiment that is drawn, the article breadth accelerated to 200m/min from 30m/min in 90 seconds.In this process, must apply described non-driven the moment of inertia and the effective moment of inertia just that rubs.In boost phase, described web tension descends in the clamped position back and rose before ensuing clamped position, because described non-driven roller obtains quickening.
A kind of stable status appears again after quickening, this state in Fig. 2 on the right side of chart roughly as can be seen from t=150s.In this stable status, must apply described non-driven moment of friction.This just cause non-driven axle and in article breadth trend the higher web tension in ensuing clamped position back be used to drive described non-driven axle because described clamped position must consume a power.This power is equivalent to differ from 17 between shown web tension change curve 13 and 14.
Fig. 3 exemplarily shows the registration error that produces on the processing unit.In chart 20, drawn the change curve of register partial difference about the time, wherein draw two Figure 23 and 24 corresponding to different elastic modelling quantity.In chart 20, drawing described registration error about the time t on x-axle 21 on the y-axle 22.Drawn the boost phase from 30m/min to 250m/min in 90 seconds at this with material with different elastic modelling quantity.Described acceleration and the effective moment of inertia that remains to be considered are identical respectively concerning two curves.The material of the breadth of curve 23 correspondences has about 8.610
9N/m
2Elastic modelling quantity.The material of the breadth of curve 24 correspondences has about 3.610
9N/m
2Elastic modelling quantity.When identical and acceleration was identical in the moment of inertia of described non-driven roller, the Different Effects of dynamic registration error was tangible.
At last, Fig. 4 shows the change curve 33 of the registration error that produces on the processing unit when use is of the present invention.In chart 30, drawing described register partial difference about the time t on x-axle 31 on the y-axle 32.Drawn 30 seconds boost phase at this.Clearly, described register partial difference almost disappears.
Self-evident, in shown accompanying drawing, only show a kind of particularly preferred embodiment of the present invention.In addition, can under the situation of not leaving scope of the present invention, consider any other embodiment.
