Description
Technical field
The utility model belongs to printing machinery registration technology field, is the improvement for the web press cover Barebone that uses colour code alignment mode specifically.
Background technology
Web press adopts colour code alignment mode more, by benchmark colour code and the time of actual colour code appearance or the length of appearance, printing registration device control compensating roller or servomotor automatically adjust by the algorithm of agreement, thereby realize vertical and axial alignment.When the printing scanning head runs into the color that can't discern, as printing chalk or colourless or light gloss oil on the white substrate, during printing ink etc., printing machine can't be realized the colour code target alignment mode of checking colors to the colour cell of using this type of printing ink gloss oil.In the prior art, general settling mode carries out alignment for the pattern that adopts " colour code is to forme ", and when using this cover quasi-mode, one of them detects the benchmark colour code of printing two cursors of each colour cell, and another is then closed.Colour cell printing position signal is provided by the encoder of this colour cell axle head.
The many employings of the encoder of web press commonly used 3600 pulses weekly, so just each circumference is decomposed into 3600 five equilibriums, if the forme girth is 600mm, each unit that controls vertical precision is exactly 0.16mm so, this precision 0.1mm that carries out alignment than " colour code is to the colour code " pattern of use is much lower, when overprint error during less than 0.16mm, the cover Barebone can't be discerned, and does not also have automatic compensation certainly.
From top principle as can be seen, " colour code is to forme " cover quasi-mode mainly contains following shortcoming: 1) the forme girth more little the situation chromatography precision higher, with the production accordance of reality a certain distance is arranged.2) the selected reference colours of great majority " colour code is to forme " cover quasi-mode are designated as the colour code of first printing element, colour code is under the squeegee pressure and paper tension effect of each colour cell, unavoidably can produce some size distortions and position labile state, thereby the chromatography precision and the stability of actual colour cell under the quasi-mode are overlapped in influence " colour code is to forme ".3) " colour code is to forme " cover quasi-mode is trapped standard when deviation occurring, Chromatic Printing Control System can't be as automatically adjusting under " colour code is to colour code " pattern and compensating, need manual intervention to lock to the position of overlapping alignment request and again, operator's intensity is higher, and can't carry out adjusting.
Certainly improve chromatography precision and response time under " colour code is to forme " pattern by the halving precision that improves encoder, but this method may be brought redefining of signals collecting operation method and backoff algorithm and influence transfer of data and processing, need to revise the program and the algorithm of alignment, user or producer to equipment are new challenges, the increase that also can bring cost simultaneously.

Description of drawings
Accompanying drawing 1 is that the colour code of prior art is to colour code alignment system architecture schematic diagram;
Accompanying drawing 2 is that the colour code of prior art is to forme alignment system architecture schematic diagram;
Accompanying drawing 3 is example structure schematic diagrames of the present utility model.
Accompanying drawing acceptance of the bid keep the score state as follows: the 1-printable fabric; The 2-forme; The actual colour code of 3-; 4-benchmark colour code; 5-benchmark colour code probe; The actual colour code probe of 6-; 7-forme axle; 8-printing registration device; The pulse of 9-benchmark colour code; The actual colour code pulse of 10-; 11-pulse cover calibration signal; The 12-rotary encoder; 13-colour code dish; 14-simulates colour code; The pulse of 15-simulation colour code.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, the previous black colour code on the printable fabric 1 is the colour code of front colour cell (colour cell 1) printing, also is benchmark colour code 4; Second colour code is assumed to be redness, and this red colour code is actual colour code 3, and the reference cursor that is colour cell also is the alignment foundation.Colour code to colour code alignment system in, this benchmark colour code 4 was popped one's head in 5 o'clock by the benchmark colour code, rectangular pulse A, B can occur on oscillogram.Red colour code also claims actual colour code 3 for treating the colour code of alignment colour cell (colour cell 2) printing.Actual colour code 3 was popped one's head in 6 o'clock by actual colour code successively, two rectangular pulse C, D can occur on oscillogram.Printing registration device 8 is by benchmark colour code and the time of actual colour code appearance or the length of appearance, and registration device control compensating roller or servomotor automatically adjust by the algorithm of agreement, thereby realize vertical and axial alignment.Punctual with colour cell 1 cover when colour cell 2, lock pulse A and D in same sweep gate can realize the alignment locking and carry out error compensation automatically.
When the colour code of print couple printing is water white transparency class printing ink/gloss oil, scanning head can't be discerned.In this case, most web presses will provide " colour code is to forme " pattern to carry out alignment, as shown in Figure 2, the black colour code is the colour code of front colour cell (colour cell 1) printing on the printable fabric, as the alignment foundation of the benchmark cursor 4 of colourless colour code colour cell (colour cell 2).When cursor passed through scanning head, a rectangular pulse appearred on oscillogram.Different with " colour code is to colour code " pattern is that this colour cell only disposes a benchmark colour code probe 5, is used to scan benchmark colour code 4 (black mark), when colour code passes through scanning head, a rectangular pulse A can occur on oscillogram.This moment, colour cell 2 axle head encoders 12 produced periodic pulse signal.Punctual when colour cell 2 with colour cell 1 cover, can in sweep gate, lock rectangular pulse A, this moment, rectangular pulse A and forme axle head encoder 12 some signals were set up antagonistic relations and locking, thereby realized the alignment locking.In less registration error scope, the corresponding relation error between pulse A and the code device signal is compensation automatically.But the big or shutdown when error, when printing conditions such as disconnected paper or tension variation changed, this corresponding relation can destroy and can't reduce automatically.Simultaneously, the registration error response is limited by the girth of encoder halving precision and forme.
Accompanying drawing 3 is depicted as the signal of the utility model one embodiment.The utility model mainly is simulation " colour code is to colour code " pattern, and the deficiency that " colour code is to forme " pattern exists is improved, and concrete grammar is as follows:
Install a colour code dish 13 on the forme axle 7 of forme 2 additional, the diameter and the thickness of colour code dish 13 do not have specific (special) requirements.Under possible situation, the diameter of colour code dish 13 is the bigger the better, and the quality of colour code dish 13 is light more good more.Colour code dish 13 is fixed on forme axle 7 ends (also can be installed on the mechanical drive shaft or servomotor power transmission shaft that links with forme, show in the diagram) by expansion loop or nut.Colour code dish 13 subscripts are shown with the visual colour code (can be scanned the effectively colour code of identification of probe) of or inequality specification identical with the benchmark colour code, are called simulation colour code 14 at this, and simulation colour code 14 quantity do not require.But spacing therebetween should guarantee that two adjacent colour codes can well be discerned and unlikely generation is misread or the phenomenon of pulse overlap.
As shown in Figure 3, on forme axle 7, install a colour code dish 13 additional, choose " colour code is to colour code " pattern, with another group scanning head is that actual colour code probe 6 is aimed at colour code dish 13, it is 5 constant that simulation colour code 14 on the scanning colour code dish, benchmark colour code are popped one's head in, and is used to scan benchmark colour code 4.When equipment moved, the actual colour code probe 6 of scanning colour code dish 13 produced the pulse signal of a series of five equilibriums, and these pulse signals can be corresponding to the out of phase of forme.Signal is with " colour code is to colour code " pattern input printing registration device 8 like this, be actually the colour code input on the simulation printable fabric 1,8 meetings of printing registration device " think " that these signals are that colour code produces on the printable fabric, so just can utilize " colour code is to colour code " pattern to carry out alignment.
In the application of reality, only need regulate colour cell 2 in the starting stage of equipment operation meets the requirements with reference colours target registration error, benchmark colour code 4 will form the corresponding relation of pulse signal with colour code dish 13 patrix mimic colourations mark 14, as shown in Figure 3, reference pulse A and colour code dish pulsed D, will two can realize register control after the pulse signals locking, its alignment precision and response time, precision will be basic identical with " colour code is to colour code " pattern.
