Description
Technical field
The present invention relates to the sensor of a kind of labelling on the material track of optical detection operating.
Background technology
Such sensor is such as known from EP1050843A2 or from EP2278361A1.
The sensor of labelling on the material track of optical detection operating is used for example in printer, in order to that measures and regulate if desired between the folder followed one another is so-called to version accuracy.
In printing technology, term " to version accuracy " refers to the printed monomer layer location accuracy relative to nominal position. Therefore, the respective color layer of the color part of multiple arranged in succession must accurately be stacked printing, in order to produces the image completing printing with desired color impression. Otherwise, the image completing to print seems fuzzy and is inferior in quality. Therefore, according to disturbing parameter accordingly, for instance relate to all bound pair versions or side to version.
In order to automatically calibrate version deviation, in printer and particularly in intaglio press uses so-called to version regulate. For this, in each folder namely from second folder by sensor optical detect respective markers operating material track on position.
In order to identify version mark, light source light beam is directed on track. Being returned to optical receiver in part through lens by conduction to the light of backscatter by track, this optical receiver can convert according to the respective color on time detecting track and indicate edge accordingly.
If for version mark such as selects triangle, then the time difference between the mark edge straight respectively of version mark is longitudinal tolerance to version by two of same color, and the time difference between the single mark edge to version mark is the side tolerance to version.
At next step, calculating adjustment order in the regulators from the sensor signal of optical receiver, this adjustment order is fed to corresponding to version adjustment motor. By being adjusted via to version adjustment motor, then shorten or extend the orbital path between two printing elements when week bound pair version, and when side is to version, the orbital path between two printing elements is shifted to respective side.
Although to version regulate in use these sensors, but always under certain conditions also may determine that print image in version deviation.Its major reason is in that, due to the modification multiformity of available print color and background, becomes increasingly difficult to ensure high-contrast for all combinations of print color and background and therefore reliably version measured.
Summary of the invention
Therefore, the task of the present invention is to provide a kind of sensor, and this sensor is not when about all possible combination that can be reliably used for print color and background when can realize the loss of degree of accuracy.
This task is solved by sensor according to claim 1.
The sensor of the labelling on the material track of optical detection operating according to the present invention includes: light source, and it generates hot spot on the material track in operating, and wherein the intensity of hot spot can be controlled by driver; Optical receiver, it is for receiving the light from the reflection of hot spot aspect; Signal processing unit, it is for analyzing the output signal of optical receiver; And switch unit, it for switching between teaching model and detection pattern, and wherein under teaching model, the intensity of hot spot is changed by driver, and in a detection mode, the intensity of hot spot is kept constant by driver.
The understanding that the present invention is based on is, the modification multiformity of the raising of background and print color causes that the dynamic range at optical receiver place improves, and this dynamic range is no longer able to reliably be analyzed by ensuing signal processing unit. Therefore, when weak receive signal, signal to noise ratio is no longer enough to analyze reliably, and when strong when receiving signal, the output signal of optical receiver becomes saturated, and therefore cannot be used for contrast equally and compare.
But if according to the present invention arranges teaching model in the sensor, under this teaching model, the intensity of hot spot is changed by driver, then the accessible reliability that can targetedly compensate the dynamic range therefore sensor that receive signal is promoted to close to 100%.
Alternatively also or additionally, it is possible between optical receiver with signal processing unit, be connected the adjustment amplifier for optimally Automatic level control.
At this, the adjustment amplifier in meaning of the present invention is the amplifier with the controlled magnification factor in variable outside.
At this, the controllable driver in meaning of the present invention is the power model of the controlled power in the variable outside having and flowing to light source.
Under teaching model, the intensity of hot spot is preferably changed into by driver so that the output signal of optical receiver is in optimum control scope. Utilize the clock frequency of currently available such as 500kHz, it is possible in version mark, perform this teaching model. At this, the clock frequency of 500kHz is corresponding to the clock cycle of 2 μ s. If suppose further that average printed mark has 5mm length and typical orbital velocity is 600m/min, then the hot spot of sensor in 500 μ s through printed mark. It is to say, when 2 μ s clock cycle, printing at one can through 250 different clocks under teaching model in labelling, in order to changes the intensity of hot spot step by step and is adjusted in optimal level.
But generally should also be as the change detecting in the output signal of optical receiver step by step in a detection mode. But being made by the position of the switch of the switch unit according to the present invention, signal processing unit may identify which: sensor is currently under teaching model and still runs in a detection mode. Owing to teaching model is just expired only in the short time period of a few μ s or in the short-circuit journey of several μm as set forth above, the actual determination signal that should be identified during teaching model therefore even counter can be released for signal processing unit.For this, stroke sensor that signal processing unit can employ other systematic parameter, such as track cylinder or the orbital velocity being currently stored in system.
The principle that optimal level controls and/or suitable strength controls be similar in a certain way audio compressor or audio extender are used in acoustic technique, such as during SoundRec when recording the previously given technological limit of medium restriction or extended dynamic scope.
But such as also use audio compressor to process each sound component in sound figure targetedly. It is thus possible, for instance the song of people has the dynamic of height naturally, it makes problematic with undressed form, makes singing occur in the foreground relative to all the other vestiges. But be by mean of audio compressor can these level fluctuations balanced, be achieved in persistently high average level and the signal existence being therefore obviously improved.
In so-called downward audio compressor, in acoustic technique, the audio input signal of amplifier is reinstated less magnification factor from certain level and is amplified. And in so-called upwards audio compressor, the audio input signal being in below certain level of amplifier is amplified by higher magnification factor. Of course, it is also contemplated that the nonlinear characteristic curve of the combination of two kinds of principles and magnification factor, wherein under any circumstance all carry out the compression of the dynamic range of audio input signal.
When audio input signal had small dynamic range, there is reverse situation. In this case, it is used for improving dynamic range by audio extender. It is to say, this refers to, slight passage is amplified more slightly, and loud passage is amplified more ringingly.
Not only compressor is can serve as but also can serve as expander according to the adjustment amplifier of the present invention and/or the controllable driver according to the present invention.
According to a preferred implementation, optical receiver is installed so that the direct reflected light of hot spot is fallen on optical receiver. If in this case the surface of the span of control of optical receiver with the delustring of the material track of operating is coordinated mutually, then optical receiver quilt extremely toning when the reflective surface of the material track of operating. On the contrary, if the span of control of optical receiver coordinated mutually with reflective surface, then the blackout on the surface of delustring is in noise. It is to say, there is the typical case of HDR so that use compression method described above.
According to another preferred implementation, optical receiver is installed so that being fallen on optical receiver by the light of diffusing scattering of hot spot. If the span of control of optical receiver is coordinated mutually with the frosting of the material track of operating in this case, then obtain, when optical receiver is in the reflective surface of material track of operating, the signal level that the established angle according to optical receiver is less, but this signal level is likely to for colour switching to be little to distinguish with frosting. Accordingly, there exist the situation of low-dynamic range so that use extended method described above.
To the analysis of the light being directly mirrored of hot spot and the analysis by the light of diffusing scattering of hot spot is respectively provided with merits and demerits. Therefore, preferred embodiment specify according to another: the light that is directly mirrored and by the light of diffusing scattering in two reception passages separately analyzed, and then will provide for the reception passage of more reliable signal respectively for analyzing.
Determine that optimal level control and/or optimal strength different schemes occur when encouraging actual.
A kind of scheme is in that, carries feedback signal for determining optimal level control and/or encouraging for optimal strength to signal processing unit. It means that the output signal regulating amplifier is observed, and it is adjusted according to the obtained envelope curve power to controllable driver and to the magnification factor regulating amplifier so that desired control occurs. The method can be applied easily, but the shortcoming with certain ineffective time so that in the other situation of little poor contrast, it is likely to still nonrecognition transient process.
Another kind of scheme especially for the application of time-critical is in that, it is possible to carry feed-forward signal for determining optimal level control and/or encouraging for optimal strength to signal processing unit. For this, before original optical receiver, connect another optical receiver. According to connect preceding optical receiver obtained envelope curve, then to the power of controllable driver and to regulate amplifier magnification factor performs adjustments so that connection posterior optical receiver place appearance desired control. If depending on the contrast difference of edge shape reliably identifying labelling on the material track of operating, then must assure that in addition in the method: just do not carry out in poor contrast other time to the power of controllable driver with to the adjustment of the magnification factor regulating amplifier speculating. Due to this requirement, it may also be envisaged that, before original optical receiver, connect multiple optical receiver so that obtaining multiple feed-forward signal in different levels, described feed-forward signal show that degree of accuracy promotes step by step. Therefore, such as can be optimized according to compression method and/or according to extended method in the first order of dynamic range, and determine in the second level and do not allow the power to controllable driver and magnification factor is performed the time adjusted so that then exist for optimal level control and/or all desired parameters for optimal strength excitation in last level. Further, it is also possible to imagine similarly, different feedforward levels is not connected but in parallel. It is also contemplated that the series connection of the combination of different feedforward levels and parallel connection.
It has been shown that at least four situation should be distinguished when optimal level controls and/or when optimal strength encourages, in order to the labelling on the material track of reliable fashion optical detection operating. At this, it is in the following assumed to: the light being directly mirrored of hot spot is fallen on optical receiver. Additionally, the similar situation about being fallen by the light of diffusing scattering on optical receiver considering to be applicable to hot spot.
The background of the material track of operating has frosting, and labelling itself is also made up of delustring color. In this case it will be appreciated that first the magnification factor regulating amplifier is adjusted on intermediate value, and then intensity excitation is chosen as so that the control of the output regulating amplifier when delustring background is similarly in intermediate range. Colour switching (level raises or level declines) based on labelling then reliably can be identified at optical receiver place.
The background of the material track of operating has reflective surface, and labelling is made up of delustring color. In this case it will be appreciated that first the magnification factor regulating amplifier is adjusted on intermediate value, and then intensity excitation is chosen as so that the control of the output regulating amplifier when reflective background is in upper extent. Then, the conversion on the delustring color of labelling causes that strong level declines, and this level declines and reliably can be identified at optical receiver place.
The background of the material track of operating has frosting, and labelling is made up of reflective color.In this case it will be appreciated that first the magnification factor regulating amplifier is adjusted on intermediate value, and then intensity excitation is chosen as so that the control of the output regulating amplifier when delustring background is in low scope. Then, the conversion on the reflective color of labelling causes that strong level raises, and this level raises and reliably can be identified at optical receiver place.
The background of the material track of operating has reflective surface, and labelling itself is also made up of reflective color. In this case it will be appreciated that first the magnification factor regulating amplifier is adjusted on intermediate value, and then intensity excitation is chosen as so that the control of the output regulating amplifier when reflective background is similarly in intermediate range. Colour switching (level raises or level declines) based on labelling then reliably can be identified at optical receiver place.
Situation four kinds described totally observed display, being marked at optical receiver place and not only level can have been caused to raise, but also can cause that level declines on the material track of operating. Now in order to reliably detecting is decline level rising or level to distributing to the contrast variation from background to labelling or distribute to from the contrast variation being tagged to background on the contrary, time window already mentioned above can be used again, in described time window, it is blocked to the power of controllable driver and to the change of the magnification factor regulating amplifier. Described time window is determined by the feedforward level provided for it so that the sensor of the labelling on the material track detecting operating originally can adopt lower row logic:
If occurring that in time window a level raises and a level declines or occurs that a level declines and a level raises on the contrary, then it is labelling.
And if occur in time window multiple level raise and/or multiple level decline, then these level can not be explicitly assigned to labelling. Then, the corresponding error reporting of superior system forwards.
Specifying according to another preferred implementation, light source is high-capacity LED (LED represents light emitting diode or light emitting-type diode or photism diode). Now, high-capacity LED can be used for the light intensity in 50 candelas (luminous intensity unit, symbol: cd) scope and can be used for until 100 lumens (unit of luminous flux, symbol: Im) when hundreds of milliampere diode current. High-capacity LED can be used as the monochromatic LED with the spectrum of white light color and the distribution of the approaches uniformity in visible range. But alternatively, it is also possible to employing can multiple colour light emitting so-called multi-colored led. For example, it is possible to by 3 LED chips of basic colors red, green and blue or even basic colors red, green and blue and white 4 LED chips are arranged on SMD carrier.
LED driver such as can realize with the form of the pulsewidth modulation of two superpositions. Utilize pulsewidth modulation to adjust the brightness of effective diode current and then diode, and the clock of corresponding LED is responsible in the second pulsewidth modulation. As known from fiber waveguide transmission technique field, the clock frequency in 1 megahertz range can be realized without problems when LED. The clock of LED this have the advantage that in addition, also has dark value (LED closedown) can use in each pulse except brightness value (LED unlatching). After LED amplifier, then can deduct brightness value from dark value so that interference effect can be eliminated whereby.
Specifying according to another embodiment, optical receiver is color-electric pressure converter. Color-electric pressure converter such as can be made up of 3 photodiodes, is connected to the color filter of basic colors red, green and blue before described photodiode. Photoelectric current is the tolerance that the light in respective wavelength scope is incident. Then, after each photodiode, it is connected to current-voltage converter so that output voltage is finally the tolerance that the light in respective wavelength scope is incident.
According to the present invention, after this voltage, connect from now on the adjustment amplifier controlled for optimizing level.
Therefore, when measuring three basic colors red, green and blues, three adjustment amplifiers are then correspondingly also needed to.
A particularly preferred application according to sensor of the invention is the application to the measuring cell in version actuator as printer.

Detailed description of the invention
Fig. 1 illustrate according to first embodiment according to sensor of the invention 101, after this sensor is disposed in the folder 102 of intaglio press. Folder 102 schematically shows printing cylinder 103(roller platen) and shaping drum 104. Each folder of intaglio press follows one another layout, and wherein material track 105 is without interruption through each folder. Roller platen 103 is driven when contacting with material track 105 by shaping drum 103 in the way of power cooperation. In order to be conducive to the color transmission from shaping drum 104 to material track 105, material track can arrive roller platen 103 not long ago with electrostatic charging.
Each folder prints labelling (also known as to version mark) on material track. Figure 1 illustrates three labellings and labelling 106, labelling 107 and labelling 108. It means that material track 105 passes through three folders. That is, for instance labelling 106 is derived from the first folder, labelling 107 is derived from the second folder, and labelling 108 is derived from the 3rd folder.
Sensor 101 is provided with the high-capacity LED 109 with white light emission as light source. LED109 is by the LED driver that can encourage to supply power, and wherein power can be controlled by control and analytic unit.
The light beam generated by LED109 leaves sensor 101 by the mirror 111 that can partly penetrate and via lens 112, and generates hot spot 113 on material track. Surface according to material track, the light of hot spot 113 radiation diagram specific to respective surfaces is reflected. A part for described reflected light is detected by lens 112, and the mirror that can be partly penetrated is transmitted on optical receiver 114.
Optical receiver 114 is made up of three photodiodes in principle, and described photodiode is respectively provided with the preceding wave filter of connection of basic colors red, green and blue. The photoelectric current of three photodiodes is transmitted to adjustment amplifier 115 by current-voltage converter.
Because three photoelectric currents must be exaggerated, so regulating amplifier 115 to be actually three amplifiers separately, their magnification factor can also be separately controlled by three level regulators separately.The outfan of three amplifiers is also analyzed dividually by control and analytic unit 116. Additionally, control and analytic unit 116 also control level actuator dividually. But for the sake of simplicity, hereinafter this whole assembly is referred to as adjustment amplifier 115.
The output signal 117 regulating amplifier 115 is fed to control and analytic unit 116. Control and analytic unit 116 have again three outfans, namely for controlling to adjust the first control output end 118 of the magnification factor of amplifier 115, for controlling the second control output end 119 and the signal output part 120 of LED driver, from described signal output part 120, sensor signal and measurement result are handed to higher level to version actuator by fieldbus (such as Ethernet electric lines of force (Powerlink)).
For optimal level control and/or in order to optimal strength encourages, control to analyze the level of the output signal 117 regulating amplifier 115 with analytic unit 116. If level toning, then control and the magnification factor regulating amplifier is reduced 10dB by control output end 118 by analytic unit. If also there is toning after this reduction always, then in the value before the magnification factor regulating amplifier being reset to again, and then pass through control output end 119 by the power reduction 10dB of LED driver 110. This process repeats always, until output signal 117 no longer toning. Then, this output signal 117 optimally controls by adjusting the magnification factor regulating amplifier 115 accordingly via control output end 118.
It is to say, the optimal level according to Fig. 1 controls and/or optimal strength excitation carries out according to feedback principle. But in the application of real time critical, the shortcoming that feedback principle has intrinsic ineffective time. This shortcoming can be avoided by when the structure according to feed for ward principle as shown in Figure 2.
Fig. 2 illustrate according to the second embodiment according to sensor of the invention. Only explain the principle difference with Fig. 1 below. All the other consult the description according to Fig. 1.
Sensor according to Fig. 2 is made up of feedforward level 201 and original measurement level 203 now. Measuring level 203 and obtain feed-forward signal by front feeder line 202, this feed-forward signal comprises the rough estimate value of the level information about labelling and positional information. These information then tested magnitude 203 controls for optimal level and/or for optimal strength excitation. Then pass through signal output part 204, sensor signal and measurement result and hand to higher level to version actuator by fieldbus (such as Ethernet electric lines of force).
The model of action of feedforward level 201 is equal to the model of action of the sensor 101 according to Fig. 1 in principle, say, that the optimal level of feedforward level 201 controls and/or optimal strength encourages based on the feedback principle described in the first embodiment. Due to ineffective time, although therefore feedforward level 201 only can determine that the rough estimate value of the level information about labelling and positional information, but these estimated values are enough to ensure that optimal level control and/or optimal strength excitation for measuring level 203. Additionally, the other model of action about feed for ward principle consults being described above in description beginning.
Fig. 3 illustrate according to the 3rd embodiment according to sensor of the invention. Only explain the principle difference with Fig. 1 below. All the other consult the description according to Fig. 1.
When sensor 301 according to Fig. 3, being in that with respect to the difference of the sensor 101 of Fig. 1, the light path of present light beam extends to so that can abandon the mirror that use can be semi-permeable. This is advantageously, it is possible to avoid by can the loss that causes of semi-permeable mirror. To achieve it, the optical axis 303 of the optical axis 302 of light source and optical receiver is inclined by so that the angle of incidence of optical axis 302 exactly corresponds to the angle of emergence of optical axis 303.
Fig. 4 illustrate according to the 4th embodiment according to sensor of the invention. Only explain the principle difference with Fig. 3 below. All the other are consulted according to Fig. 1 and the description according to Fig. 3.
When sensor 401 according to Fig. 4, being in that with respect to the difference of the sensor 301 of Fig. 3, the angle of incidence of optical axis 402 is no longer correspond to the angle of emergence of optical axis 403. This causes, it is to avoid from the directly reflection of material track one side. More precisely, only also have hot spot be reflected to optical receiver by the light of diffusing scattering so that optical receiver less toning when the strong reflection surface of material track. Sometimes, it is also possible to expect, by combined for two kinds of layouts according to Fig. 3 with according to Fig. 4, as this such as described in EP2278361A1.
