Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, soft version back of the body mark is printed on the paper tape material back side and prints dark together colour code, the 1st edition printed patterns completed by intaglio printing unit, adopt gravure apparatus, the 2nd edition printed patterns completed by cylinder printing element, adopt cylinder printing equipment, the 3rd edition embossed pattern completed by embossing units, adopts embossing printing equipment; At each unit discharge end, a color mark sensor (being single electric eye) is set, each color mark sensor is all realized signal with chromatography controller and is connected, and chromatography controller is connected respectively with the encoder for servo motor of unit roller.
The model that color mark sensor (photoelectric sensor) adopts is SICK DC 10.
Chromatography controller controller as a whole, for storing colour cell program prepared in advance and carrying out chromatography computing, carries out chromatography action.
Full servo back head-stamp brush of the present invention and gravure, cylinder, embossing, to version control method, are specifically implemented according to the following steps:
Step 1, first by one group of complete servo soft version back of the body head-stamp brush device at the paper tape material back side, print successively the colour code (mark) of one dark color according to setting interval, the spacing of each colour code is uniform, the mark printing out by this printing equipment has the advantages that precision is high, is the basis of this automatic overprint system.
Step 2, secondly, be printed on the paper tape material of back side colour code again through three editions printings, be that paper tape material is by follow-up intaglio printing, when cylinder printing and embossing units, at each unit discharge end, a color mark sensor (being single electric eye) is set, detect respectively the current back of the body red ink paste used for seals mark of paper tape material by single electric eye of each unit discharge end setting, if current back of the body red ink paste used for seals mark and intaglio printing, cylinder printing, embossing icon is in the time of alignment position, record respectively the position of each unit drives encoder for servo motor, and benchmark using this position signalling as the chromatography of each unit, and store in chromatography controller.
Step 3, because the back of the body red ink paste used for seals target spacing on paper tape material is uniformly, no matter how machine speed changes, the invariant position of the each group of encoder for servo motor that step 2 is stored.In intaglio printing, cylinder printing, in embossing printing process, each unit detects back of the body red ink paste used for seals timestamp by single electric eye separately, Color mark signal is transported to chromatography controller, if while there is deviation in the reference position that the position of this unit encoder for servo motor and step 2 record, directly adjusted the phase place of this unit (colour cell) encoder for servo motor by chromatography controller, make this unit encoder for servo motor pulse position identical with the reference position of storage before, to guarantee the accurate of each unit chromatography, reduce interacting between each unit, improve overall chromatography precision.
With reference to Fig. 2, the complete servo soft version back of the body head-stamp brush device structure using in the inventive method is, roller A1 was installed between the wallboard of frame both sides, crossed roller B4, the roller 5 of undertaking the printing of, roller 8, anilox roll 9, roller 5, roller 8, the anilox roll 9 of undertaking the printing of tangent contact successively, the driving end of swing arm 3 is connected with cylinder 2, the rubber roll of swing arm 3 other ends is connected with the rotating shaft of the roller 5 of undertaking the printing of, and the roller 5 of undertaking the printing of is coaxially connected with traction servomotor 14; The mount pad of roller 8 and anilox roll 9 is connected with pedestal by line slideway 13, realization slides axially, the power transmission shaft of roller 8 and roller servomotor 17 are in transmission connection, roller 8 is connected by meshing transmission with anilox roll 9 by roller gear 15, anilox roll gear 16, the power transmission shaft of roller 8 also with from version cylinder 6 is connected, the power transmission shaft of anilox roll 9 is connected with damping cylinder 7, the mount pad of anilox roll 9 is provided with squeegee pressure and adjusts knob 12, the scraper mechanism 10 of anilox roll 9 is provided with inking pressure and adjusts knob 11, realizes moving left and right in Fig. 2.
As shown in Figure 2, undertake the printing of roller 5 (traction steel rider) by traction driven by servomotor; In swing arm 3, with rubber roll, realize traction function; Roller 8, by roller driven by servomotor, can make roller 8 clutches from version cylinder 6, printing knob 12 capable of regulating squeegee pressures; Anilox roll 9 is connected by a pair of roller gear, anilox roll meshed transmission gear with roller 8, in the time stopping printing, damping cylinder 7 promotes to move after anilox roll 9, make roller 8 and cable roll 9 form certain gap but gear is not thrown off, cable roll 9 does not stop operating, reach damping effect, ink transfer pressure is adjusted by squeegee pressure knob 11, scraper mechanism 10 adjustable doctor angle and the pressure of supporting installation on cable roll 9, and the mark precision that this printing equipment prints out is significantly improved.
Automatic overprint control method of the present invention, required colour code is printed on to the back side of stock in flexographic printing mode, single electric eye is easy to identification, colour code is as the benchmark colour code of automatic overprint, intaglio printing, cylinder printing, knurling rolls are single serve transmission, printing, keep when embossing every group synchronous, but that printing and embossing phase place are distinguished is adjustable, on printing, knurling rolls axle head, approach switch is installed, as mechanical zero.First, manually carry out after every alignment of the same colour, chromatography controller is arrived as zero point in storage true qualities encoder for servo motor position, secondly, in the time of chromatography subsequently, detect every look colour code position by photoelectric sensor, automatically calculate colour code and the phase difference between zero point by chromatography controller, if chromatography is accurate, this phase difference is steady state value, if have deviation with standard value, by chromatography controller control servomotor, adjust roller position corresponding with reference position, at roller (gravure printing roller, cylinder roller, knurling rolls) manufacturing process external diameter respectively has deviation, chromatography controller can utilize corrected parameter to be solved, like this in existing cylinder printing, in gravu re system and synchronous embossing print system, can realize completely automatically version is printing automation and carries out off-line operation.
The full-automatic overprinting method control procedure of the present invention is simple, easy to operate efficient, realize completely and automatically detect and adjust, do not need follow-up artificial observation operation, significant wallpaper printing and the synchronous embossing chromatography precision of improving, experimental results show that, can reach ± 0.2mm of printing element automatic overprint precision, can reach ± 0.3mm of embossing units automatic overprint precision, for high-quality wallpaper provides Reliable guarantee.
