Description
Technical field
The utility model relates to printing machinery, especially a kind of roll web location print system.
Background technology
Printing for roll web, existing enterprise adopt more line compound/mode peeled off, compound/stripping process becomes the part of printing production line, whole production line aluminizes roll web, peel off pet layer behind the compound working procedure such as dyeing, and the transfer paper of producing is directly entered next step pattern printing on line.The result of this production technology is that production line draws longly, and floor space is big.Because the speed of production of most printing machines is higher than the speed of production of compounding machine far away, compound/stripping process is consuming time long and cause subsequent technique slow excessively, can't improve print speed printing speed, as long as there are some links to break down in process of production, then first finished paper of sliver is all cancelled, and causes very big waste.And because the trouble point is many, the control point is also many, and production efficiency is restricted.
In addition, because roll web is at the diverse location of reel, the suffered tension force of paper is different with deformation, and the open and flat back of roll web length can slightly change, so continuous reel paper feed accumulated error can strengthen rapidly, makes follow-up chromatography operation lose accurately.Simultaneously, the multi-stage mechanical transmission of long distance runs into situations such as paper feed skids through regular meeting, directly drops into printing and must lose positional accuracy.And, must avoid in the version seam printing on the transfer paper.
Summary of the invention
The utility model provides a kind of roll web location print system, purpose is to allow the full speed running of printing unit, significantly enhance productivity, even and the somewhere has fault that too big loss takes place also can not cause, guarantee that simultaneously the printing position is accurate on the transfer paper original pattern, avoid smoothly version seam or with the accurate alignment of location pattern of paper surface.
It is characterized in that of described web printing navigation system: system is by the system that unreels 1 of band contraposition splicing function, and independent tension force control control system 4 and printing unit 3 compose in series.
Independent tension force control control system is made up of the main frame of band microprocessor and peripheral detection head 5, encoder 6, servomotor tension force control executing agency 2; Detection head 5 and encoder 6 are connected to the input interface of microprocessor, and servomotor tension force control executing agency 2 is connected with the output interface of microprocessor by power amplifier.
The radium-shine cursor that detection head 5 detects on the roll web, encoder 6 is collected corresponding positional information simultaneously, and microprocessor is according to this photo-sensor signal will that collects and the rotating speed of encoder pulse signal controlling servomotor.
The utility model with former line compound/that stripping process changes off-line into is compound/peel off, the production line initiating terminal add the system that unreels of band contraposition splicing function and independently the paper tension controlling organization printing unit can accurately be located, print smoothly.
The utility model has the advantages that: floor space is significantly dwindled, and production efficiency significantly improves, and reduce at the control point, and loss significantly reduces, and fault rate descends, and the printing position is accurate continuously, accurately avoids the version seam.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is roll web (transfer paper) schematic diagram that enters production line.
Among the figure: the system that unreels of 1-band contraposition splicing function, 2-servomotor tension force control executing agency, 3-prints unit, 4-independence tension control system, the 5-detection head, the 6-encoder, 7-paper, literal on the 8-paper and pattern unit, cursor on the 9-paper, version seam between the 10-repetitive, the roll web that 11-repetitive, 12-have spliced.
The specific embodiment
Below the utility model is further specified: consult 1,2.For realize smoothly off-line of the present utility model compound/stripping technology, adopted following scheme:
1, roll web has been compounded with radium-shine cursor 9 or has not printed cursor and have version seam 10 to exist in the compound/stripping process of off-line, the fixed position of each repetitive 11 is (at the edge, not in the final finished printing zone, promptly not in literal and pattern unit 8) be printed on the cursor 9 of high position precision or version seam 10 is arranged, be used to provide the length of making repetitive to independent tension control system 4 and adjust and position probing, and can offer printing unit identification repetitive position.
2, roll web is without interruption can not interrupt.Therefore in the initial system that unreels 1 that needs band contraposition splicing function of production line, different independently roll webs accurately is spliced into continuously and satisfies the coil paper 12 of repeatable accuracy requirement by repeatable position, because splicing system carries the coil paper buffer storage, can not influence speed of production.
3, the every repetitive length unanimity of strict adjustment before entering the printing unit is accurate to guarantee follow-up printing chromatography position, and accumulated error is controlled at claimed range.This requirement is finished by independent tension control system 4, independent tension control system 4 detects radium-shine cursor 9 or version seam 10 by photoelectric sensor, while is in the phase place of fixed range place capturing and coding device 6, obtain positive and negative error in length through converting, driving servomotor tension force control executing agency 2 with this quickens or slows down to rotate, because paper can bring small length variations by tension force, can adjust the accurate chromatography of repetitive 11 length feasible printing unit with this.
4, print unit and carry position detecting device, decide the printing position, and skip version seam 10 or directly detection version seam 10 positions and skip version seam 10 by identification cursor 9 positions.
Described web printing navigation system is by the system that unreels 1 of band contraposition splicing function, and independent tension force control control system and printing unit 3 compose in series.Independent tension force control control system 4 is made up of the main frame of band microprocessor and peripheral detection head 5, encoder 6, servomotor tension force control executing agency 2; Detection head 5 and encoder 6 are connected to the input interface of microprocessor, and servomotor tension force control executing agency 2 is connected with the output interface of microprocessor by power amplifier.
Radium-shine cursor or version that detection head 5 has photoelectric sensor to detect on the roll web are stitched, encoder 6 is collected corresponding positional information simultaneously, because detection head 5 and encoder 6 relative distances are fixed, microprocessor is according to this photo-sensor signal will and the encoder pulse signal determining repetitive length that collect, thereby the rotating speed of control servomotor is adjusted.
Then control the servomotor rotating speed when detecting tested length cell length off-rating, reduce tension force, then control the servomotor rotating speed when detecting tested length cell length less than rated value, add hightension, so that repetitive length is controlled in the permissible accuracy scope, make the error in length scope be controlled at ± 0.3mm within.
Since unreel system 1 and tension control system 2 relative compound/the stripping system engaged position is much smaller, has therefore saved floor space.
Can realize continuous high-efficient web printing accurately according to the be linked in sequence system's of unreeling 1 tension control system 2 and printing unit 3 of Fig. 1.
