Among the figure 1, the chromatography colour code, 2, photometer head, 3, chromatography colour code testing circuit, 4, the control computer, 5, the reversible electric machine control circuit, 6, motor and guiding mechanism, 7, synchronous head, 8,9, the chromatography space, 10, first forme colour code, 11, second forme colour code, 12, the 3rd forme colour code, 13, light source bulb, 14, diaphragm, 15, collector lens, 16, photoelectric device, 17, support, 18, the chromatography control cabinet, 19, photometer head, 20, the photometer head support, 21, reflecting plate, 22, drying box, 23, colour code, 24, reversible electric machine, 25, roller, 26 are adjusted in chromatography, forme.
Fig. 1 and Fig. 2 show the annexation of the utility model various piece, and the colour code on the forme is transferred on the printed article, and forming checked object is colour code 1.The incident light of photometer head 2 is beaten on " path " that colour code passes through, and reverberation enters photometer head 2, forms the signal of telecommunication by photoelectric device 16, and this signal is sent into chromatography colour code testing circuit 3, by amplification, differential, pulse shaping, forms colour code and space two paths of signals.Above-mentioned two paths of signals is sent into control computer 4, seek synchronous head by computer, calculate overprint error, and press the PID control law and calculate regulated quantity, form the control signal of certain hour width again by 8253 Timer, corresponding solid-state relay is connected, thereby drive reversible electric machine by certain direction rotating certain angle, by the displacement of dancer rools, reach the purpose of revising overprint error again.
The colour code 1 that this cover printing device is adopted as shown in Figure 3.Its characteristics have two.First forme of the first adopts the combination colour code, and it is made up of synchronous head 7 and chromatography space 8,9.It two is that the chromatography colour code 10,11 of follow-up forme should accurately " be inserted " " chromatography space " center, when the chromatography colour code of follow-up forme departs from chromatography space center line, overprint error has taken place promptly.Synchronous head is the beginning flag that detects, just because of designed synchronous head, just can save the address pulse generator.
The target of checking colors scanning is finished by photometer head.As shown in Figure 4, the light that the light source bulb 3 of photometer head 2 sends is converged to luminous point by diaphragm 14 by collector lens 15, project on the colour code 1 of printed article, because printed article and colour code are different to absorption of incident light, make reverberation that the variation of energy take place, the light that changes reflexes on the photoelectric device 16 signal of telecommunication that changes.This signal has reflected the colour code situation.
