The specific embodiment

Fig. 1～Fig. 3 represents to have the schematic configuration of the gravure printing presses of control device of the present invention.This gravure printing presses has: the feeding portion 2 that is printed thing 1 that is made of sheet materials such as coil paper that is rolled into reel or resin-made membranes, the thing of sending from this feeding portion 21 that is printed is applied regulation tension force and it is supplied to the feeding portion 4 of preheater 3, a plurality of first～the 4th printing elements 5～8 along the landline setting that is printed thing 1 of deriving from above-mentioned preheater 3, thing 1 applies regulation tension force and with its efferent of drawing 9 to being printed of sending from the 4th printing element 8 of final stage, and be printed the reeling end 10 that thing 1 batches after the printing that will draw by this efferent 9.

Above-mentioned first～the 4th printing element 5～8 is provided with Printing Department 13, its have the galley tube 11 that is coated with printing ink on the side face and be arranged on described galley tube 11 above and the described thing 1 that is printed is crimped on pressure cylinder 12 on the galley tube, and be provided with donor rollers 14 and the distributing roller 15 that is printed thing 1 channeling conduct to above-mentioned at the entrance side and the outlet side of described Printing Department 13.In addition, the drive motors 16 that above-mentioned galley tube 11 is rotated driving is separately positioned on each printing element 5～8, and in the downstream of above-mentioned distributing roller 15 drier 18 with a plurality of guide reels 17 is set.

Between above-mentioned distributing roller 15 and drier 18, be provided with mark sensor 19, it is used for detecting the coating position that is coated in the printing ink that is printed on the thing 1 in Printing Department 13 is the printing position, in the correction mechanism 21 that is arranged at control module 20, according to the detection signal of described mark sensor 19 outputs, judge whether that 11 pairs in the galley tube that produces by above-mentioned each printing element 5～7 is printed the printing position dislocation (aiming at dislocation) that thing is implemented successively.Particularly, in above-mentioned mark sensor 19, the galley tube 11 that detects respectively by second～the 4th printing element 6～8 appends to the record mark that is printed on the thing 1 and appends to the interval of the record mark that is printed on the thing 1 by being positioned at first of its preceding-stage side～galley tube 11 of the 3rd printing element 5～7, and assay intervals and the predefined base interval (for example 20mm) to described record mark compares in above-mentioned correction mechanism 21, when the deviation of the assay intervals of above-mentioned record mark and base interval is setting when for example 1mm is above, then judge in this printing element, to have produced the printing dislocation.

Above-mentioned correction mechanism 21 constitutes, when judging the assay intervals that produced the record mark in any one of second～the 4th printing element 6～8 deviation with base interval is that printing more than the setting is when misplacing, to the printing element that produces described printing dislocation (below, be called discrete cell as required) a version tube phase place adjust, revise the control signal of above-mentioned printing dislocation to drive motors 16 outputs of above-mentioned discrete cell, and the control signal that will represent described version tube direction of phase adjustment and regulated quantity outputs to the compensation mechanism 22 of the carrying out version tube phase compensation in the printing element (below, be called the rear-stage side unit as required) of the rear-stage side that is positioned at above-mentioned discrete cell.

The compensation mechanism 22 that is arranged in the above-mentioned control module 20 constitutes, when adjusting by the version tube phase place of 21 pairs of discrete cells of above-mentioned correction mechanism, after the version tube phase place of rear-stage side unit being carried out initial compensation with its adjusting direction equidirectional and same degree ground, phase compensation amount after this initial compensation is reduced corresponding to elapsed time, and when the position that is printed after above-mentioned correction mechanism 21 prints the dislocation correction arrives the rear-stage side unit, after the version tube phase place of rear-stage side unit being compensated again, control the phase compensation amount correspondence elapsed time after this is compensated again and reduce with the version tube direction of phase adjustment equidirectional ground that sets by above-mentioned correction mechanism 21.Compensation rate again when accordingly the version tube phase place of rear-stage side unit being compensated again with the version tube phase adjusted amount of setting by above-mentioned correction mechanism 21, be configured to and the path that the is printed thing 1 corresponding value of having carried out between discrete cell that the printing dislocation revises and the rear-stage side unit, for example, under the path (length of landline) of above-mentioned discrete cell and rear-stage side unit and situation that the path of the printing element of discrete cell and its preceding-stage side equates, above-mentioned compensation rate again is configured to the value identical with the initial compensation amount.

Above-mentioned compensation mechanism 22 make the initial compensation of version tube phase place and the compensation rate the when phase compensation amount after the compensation reduces again reduce degree, according to revising the stroke variation that is printed thing 1 that the back produces and set printing dislocation by correction mechanism 21.Promptly, as shown in Figure 3, detection signal according to mark sensor (testing agency) 19 outputs of second printing element 6 of implementing the printing of second look, determine to have produced in above-mentioned second printing element 6 the printing dislocation, thereby this moment when controlling to the rotatable phase of the version tube 11 of second printing element 6 regulate revise above-mentioned printing dislocation after, the formed base material length L 12 of the total length that is printed thing 1 that between above-mentioned first printing element 5 and second printing element 6, is transferred amounts corresponding of temporarily stretching then with above-mentioned correction.Thereafter, because not producing the above-mentioned flexible thing 1 that is printed is imported between second, third printing element 6,7, reduce gradually with the above-mentioned accordingly stroke (base material length variations amount) that is printed thing 1 of the variation that is printed the substrate tension on the thing 1 that acts on conveying therebetween.

Like this, change when the corresponding elapsed time of stroke be printed thing 1 and be imported between second printing element 6 and the 3rd printing element 7 at its rear side the time, then because the variation of above-mentioned stroke, might be at two printing elements 6, produce the dislocation in printing position between 7, therefore as described below, change the degree that reduces of setting above-mentioned compensation rate corresponding to the stroke that is printed thing 1, initial compensation by making above-mentioned version tube phase place corresponding to elapsed time and compensate again after phase compensation amount reduce gradually, make the substrate tension of second printing element, 6 front and back keep constant, thereby prevent at above-mentioned two printing elements 6, printing dislocation between 7.

In the intaglio press of said structure, to import the printing element 5 and after it being implemented the printing of first look from the thing 1 that is printed that preheater 3 is derived, by in the printing element 6～8 that is arranged at its rear-stage side, the above-mentioned thing 1 that is printed being implemented the printing of second look later successively, and carry out polychrome printing, and according to the detection signal that is arranged on the mark sensor 19 in above-mentioned second～the 4th unit 6～8, judge whether to take place the printing dislocation, that is be more than the certain value, by the additional record mark of preceding-stage side printing element with by the assay intervals between the additional record mark of rear-stage side printing element and the deviation of predefined base interval.

Then, in judging any one (discrete cell) of above-mentioned second～the 4th printing element 6～8, produced under the situation of printing dislocation, in correction mechanism 21, version tube phase place to described discrete cell is regulated, revise the control of above-mentioned printing dislocation, and meanwhile, in compensation mechanism 22, with above-mentioned discrete cell in version tube direction of phase adjustment equidirectional and after same degree ground carries out initial compensation to the version tube phase place of rear-stage side unit, set table or operational data etc. according to predefined compensation rate, make the corresponding elapsed time of phase compensation amount after the above-mentioned initial compensation and the control that reduces.

For example, according to from implementing the detection signal of mark sensor 19 outputs of second printing element 6 of second look printing to being printed thing 1, judge the record mark in the expression first look printing position and the 21mm that is spaced apart of the record mark of representing the second look printing position, this assay intervals is only than the big 1mm of the base interval that is set to 20mm, promptly, at definite second printing element 6 is under the situation of discrete cell, the rotary speed of the galley tube 11 by making described second printing element 6 temporarily reduces, shown in the arrow A of Fig. 3,, the version tube phase place of above-mentioned second printing element 6 make it towards the direction displacement 1mm opposite with being printed thing 1 throughput direction thereby being carried out edition phase adjusted of tube.Thus, when implementing to revise the control of above-mentioned printing dislocation, the reduced 1mm of base material length (being printed the delivered length of thing 1) L12 between first printing element 5 and second printing element 6, thus revised above-mentioned printing dislocation.

In addition, in the control of revising above-mentioned printing dislocation, be positioned at the 3rd of second printing element, 6 rear-stage sides by making, the 4th printing element 7, the rotary speed of 8 galley tube 11 temporarily reduces, shown in the arrow B and Fig. 4 (b) of Fig. 3, the version tube phase place X3 that makes the 3rd printing element (rear-stage side unit) 8 towards be printed the phase adjusted amount corresponding value (1mm) of thing 1 throughput direction rightabout displacement with above-mentioned second printing element 6, and make the version tube phase place X4 court value (1mm) corresponding with above-mentioned initial compensation amount of the 4th printing element (rear-stage side unit) 8 in the same manner with being printed thing 1 throughput direction rightabout displacement.Thus, regulating the moment t0 that implements to revise the control of printing dislocation by version tube phase place to above-mentioned second printing element 6, carry out initial compensation (phase compensation), make the base material length L 23 between second printing element 6 and the 3rd printing element 7 and the base material length in its downstream dwindle 1mm respectively.Thus, can prevent between above-mentioned second printing element 6 and the 3rd printing element 7 and the tension force that is printed thing 1 between the 3rd printing element 7 and the 4th printing element 8 be subjected to the phase shift in above-mentioned second printing element 6 corrective action influence and change, and can prevent to produce the printing dislocation corresponding to mentioned strain changes.

As mentioned above, make the base material length L 23 between second printing element 6 and the 3rd printing element 7 having carried out initial compensation, with and after the base material length (the base material length between the 3rd printing element 7 and the 4th printing element 8) in downstream dwindles 1mm respectively, from this moment t0, by setting table etc. according to the compensation rate corresponding with the data A2 of the exponential curve shown in following formula (1) or predefined Fig. 4 (a), phase compensation amount after the above-mentioned initial compensation is reduced gradually, change corresponding to the stroke that is printed thing 1 that prints dislocation correction (phase adjusted of second printing element 6 is controlled) back generation by correction mechanism 21, implement to control a version phase place X3 who makes in above-mentioned the 3rd printing element 7 and the 4th printing element 8, X4 changes.

Promptly, revise to print to misplace by the version tube phase place of regulating second printing element 6 at above-mentioned moment t0, the base material length L 12 of winning between the printing element 5 and second printing element 6 is stretched, its stroke A2 represents as exponential curve shown in (1), for example changes corresponding to elapsed time shown in Fig. 4 (a).In addition, in following formula (1), X12 is the version tube phase adjusted amount of second printing element 6 that carries out at above-mentioned moment t0, and V is the transporting velocity (m/s) that is printed thing 1, and S12 is the path between first printing element 5 and second printing element 6.

A2＝X12?exp[-(V/S12)t]...(1)

In printing machine, path S12 between the path between first printing element 5 and second printing element 6 and second printing element 6 and the 3rd printing element 7 is set to 8333mm respectively, and the transporting velocity of base material (being printed thing 1) is set to 833.3mm/s, for the dislocation of the printing in above-mentioned second printing element 6 is revised, for example control, be positioned at first to making, second printing element 5, the direction of the base material contraction in length 1mm that is printed thing 1 between 6 is regulated version tube phase place, in the case, the data A2 shown in Fig. 4 (a) represents state that the stroke A2 of base material changes corresponding to elapsed time t etc.From these data A2 as can be seen, moment t0 in the control of implementing the above-mentioned printing dislocation of correction, by adjusting operation the substrate tension (acting on the tension force that is printed thing 1) between first printing element 5 and second printing element 6 is reduced corresponding to above-mentioned version tube phase place, and after temporarily producing the shortening amount of above-mentioned base material length L 12 shortening 1mm, along with elapsed time t, above-mentioned shortening amount is eliminated (minimizing).

Then, utilize detection such as timer printing dislocation correction (adjusting of the version tube phase place in second printing element 6) printing position afterwards by above-mentioned correction mechanism 21, promptly revise the printing position of stretching and whether arrived the 3rd printing element 7 owing to carrying out above-mentioned printing dislocation, confirming that above-mentioned printing position has arrived the moment t1 of the 3rd printing element 7, as Fig. 4 (b), (c) shown in, to the above-mentioned the 3rd, the 4th printing element 7,8 version tube phase place X3, X4 compensates respectively to the equidirectional of the version tube direction of phase adjustment of being set by above-mentioned correction mechanism 21 again, and with this compensation rate R31 again, R41 sets second printing element 6 for and is positioned at the 3rd of its rear-stage side, the 4th printing element 7, after the value of the path correspondence that is printed thing 1 between 8, set table exclusive disjunction data etc. according to predefined compensation rate, implement the version tube phase place X3 after control makes above-mentioned compensation again, the corresponding elapsed time of the compensation rate of X4 and reducing.

For example, the path that is printed thing 1 between first～the 4th printing element 5～8 is all set in the equally spaced common printing machine, at the moment t1 that has passed through the stipulated time of setting by above-mentioned timer, identical with the situation of initial compensation, by making the 3rd, the 4th printing element 7, the rotary speed of 8 galley tube 11 temporarily reduces, to the 3rd, the 4th printing element 7,8 version tube phase place X3, X4 compensates again, make its with above-mentioned second printing element 6 in the corresponding value R31 of version tube phase adjusted amount X12, R41 (=X12) carry out displacement (referring to the arrow B of Fig. 3) in the same direction.Thus, shown in Fig. 4 (b), (c), implement compensation again at above-mentioned moment t1, and make between second printing element 6 and the 3rd printing element 7 and after the base material length between the 3rd printing element 7 and the 4th printing element 8 dwindles 1mm respectively, in compensation mechanism 22, control accordingly since moment t1 and elapsed time t, above-mentioned phase compensation amount is reduced gradually.

After above-mentioned moment t1 implemented compensation again, corresponding elapsed time and the version tube phase place X4 that changes the version tube phase place X3 of the 3rd printing element 7 and the 4th printing element 8 were by following formula (2), (3) expression.In formula (2), (3), A2 is first printing element 5 of trying to achieve in the above-mentioned formula (1) and the variable quantity of the base material length between second printing element 6, and A3 utilizes second printing element 6 that the formula (3.1) identical with formula (1) try to achieve and the variable quantity of the base material length between the 3rd printing element 7.
