Control part 72, a predefined side among instrumentation pulse P1 and the pulse P2, the pulse of instrumentation pulse P1 sends T1 blanking time among this embodiment.Pulse transmission T1 blanking time is the time that cam 61 rotates weeks, also is ink roller 41 to do the time of moving that once comes and goes between ink foundation roller 31 and inking roller 51.In addition, the time difference of the reception of control part 72 instrumentation pulse P1 and pulse P2 is reception of impulse time difference T2.The reception of impulse time difference, T2 was, the upper strata go out going out the time difference that ink roller 41 is contacted with the opportunity of inking roller 51 respectively of ink roller 41 and lower floor.
Then, control part 72 is calculated the value of the calculating Y that reception of impulse time difference T2/ pulse sends T1 blanking time, and will the value of calculating Y and predefined desired value Z compare.At the value of calculating Y and desired value Z not simultaneously, control part 72, to a scheduled side, in this embodiment to the cam drive mechanism 63a on upper strata, send constantly and drive signal N1, and to the opposing party, in this embodiment to the 63b of cam driving gear mechanism of lower floor, send and the different driving signal N2 of driving signal N1.
The cam drive mechanism 63a on upper strata, for the cam 61 that makes the upper strata by identical driving signal N1 rotating with now same speed, and pulse P1 is also sent with same interval.Relative therewith, the cam drive mechanism 63b of lower floor, the rotating speed of cam 61 that makes lower floor by the driving signal N2 that replaces is to rotate with different so far predefined speed.Therefore, because the transmission of pulse P2 is also inequality at interval, thereby the time difference of the reception of the pulse P1 of the reception of control part 72 and pulse P2 is that reception of impulse time difference T2 also changes.
Control part 72, the new value of calculating Y and predefined desired value Z are compared, consistent or when being contained in the numerical difference between of predefined regulation, the driving signal N2 that will send to the cam drive mechanism 63b of lower floor is back to original driving signal N1 and sends.
Be preferably, desired value Z be set under 1/2 the situation, the ink roller 41 that goes out on upper strata is contacted with going out the opportunity that ink roller 41 is contacted with inking roller 51 of opportunity of inking roller 51 and lower floor, the time difference on two opportunitys is made as to greatest extent.That is, can be with the opportunity that contacts that goes out ink roller 41 and inking roller 51 on upper strata, with the opportunity that contacts that goes out ink roller 41 and inking roller 51 of lower floor, the time of half of the time that the ink roller 4 that staggers comes and goes between 1 ink foundation roller 31 and inking roller 51, and alternately contact.
Therefore, the opportunity that contacts that goes out ink roller 41 and inking roller 51 on upper strata, with lower floor go out ink roller 41 and inking roller 51 to contact opportunity approaching, or the situation of carrying out is simultaneously eliminated, thereby bring the load of the motor that drives plate cylinder 93 up and down and blanket cylinder 92, can be to disperse at interval to greatest extent.Therefore, can not cause the irregular rotation of motor 94, the gradation unequal that can prevent to produce printing surface is even.That is, do not spend operator's manpower in operation fully,, can bring the raising of the quality of printing paper by easy device and simple control.
