Abstract
A kind of printing surface of printing machine pick-up unit that coarse adjustment is carried out in zone color matching of being used for, purpose is for providing a kind of pick-up unit of printing surface of printing machine, it can reduce the influence of subjective factor, and it is poor to detect and readjust increasing of measuring-signal again when changing the forme font.Finish like this: be used for amplifying output terminal from the sensor amplifier of the measured value signal of sensor, can link to each other by the input end of the amplifier block of external world control with gain, the control input end of amplifier block links to each other with switch, and the output terminal of amplifier block links to each other with the input end of A-D converter.
Description
The present invention relates to a kind of pick-up unit of printing surface of printing machine, it can be used to the color matching of coarse adjustment zone.
European patent document EP-PSO, 095,606 discloses the method and apparatus of a kind of mensuration press printing original text sample or forme surface fit (thing), and the region-type that it finishes surperficial sleeving fastening degree by a pick-up unit with some sensors detects.Before beginning detection, calibrate each sensor with checking fringe with minimum and maximum surperficial fit.
Regulate the sensor on printing example or single next door by the one or more sensors in the further calibration detection apparatus or additional sensor.Simultaneously, all the sensors is regulated in identical value.This calibration and adjusting are operated in calibration areas on printing example or the die and the calibration range and finish.Utilize printing example surface seal type and have repeatability than being easier to this invention.
By calibration striped, calibration range and the font of printing example or forme and the automated location identification of dimensions, this measurement mechanism is applicable to the original text sample of different fonts and different size.
This detection method and the shortcoming of finishing the used equipment of this method are: when the forme font not simultaneously, it must redeterminate and readjust the gain of measuring-signal.To operate by hand owing to this process again, so it can be subjected to the influence of subjective factor and reduce reliability.
The object of the present invention is to provide less and the printing surface of printing machine pick-up unit that reliability is higher of a kind of elapsed time.
Technical assignment of the present invention is to design a kind of like this pick-up unit, and it can reduce the influence of subjective factor and the gain of the test signal of need not resurveying and reset when changing font.
Task of the present invention can be finished by following approach: be used for amplifying the sensor amplifier output terminal from the measured value signal of sensor, increasing difference with it can be linked to each other by the input end of the amplifier unit of external world control; The control input end of amplifier unit links to each other with switch: the output terminal of amplifier unit links to each other with the input end of A-D converter.
The present invention will describe in detail according to following this embodiment.Be depicted as the block scheme of apparatus of the present invention on unique figure of accompanying drawing.Provided the sensor that is used for measuring wide look district (farbzon-en breiten spalte) among the figure, it has sensor amplifier 1,2,3, n, and links to each other with amplifier unit 4.The measuring-signal gain of amplifier unit 4 can be by extraneous conversion.The number of variable number of stages of amplification and forme font to be measured is suitable.Can measure required gain according to font, and in amplifier unit 4, carry out coarse adjustment.Available switch 5 is controlled number of stages of amplification.Both available computers was come gauge tap by the quantity that enters font, and also available for example keyboard mode comes gauge tap 5.The measured value that amplifies by the font number can convert digital signal to A-D converter 6, and delivers to the data handling machine place and handle.
