Description
Technical field
The present invention relates to the control of printing machine ink amount supply, particularly a kind of printing machine ink amount supply automatic control system that adopts computer and automatic electronic control technology that ink amount supply process in the printing machine course of work is accurately controlled belongs to computer and electronic auto-control technology field.
Background technology
Printed matter is wanted to describe diversified color, the Protean world truly.The performance of printed matter color has direct relation with the supply of printing machine ink amount, if want the color representation power that reaches careful, just need accurately control printing machine ink amount supply.In addition, modern most of pressworks all are the short run operations, once print several thousand even 100 printed matters once secondary forme, therefore to often change forme, and each color of opening the forme performance all can vary, and the ink amount supply of printing process is also just made a world of difference, and forme of every replacing will be readjusted ink amount supply, this just requires in the short as far as possible time ink amount supply process to be adjusted to optimum Working, makes printed matter reach the optimum color effect.
Adopt computer and automatic electronic control technology that ink amount supply process in the printing machine course of work is accurately controlled one of direction that has become Development of Modern Print Technique, represent five big printing machine manufacturer Heidelbergs of world's printing technology highest level, graceful rowland, Goebel, little gloomy, Mitsubishi all is applied in this technology in the middle of its printing machine, because can shorten printing process non-cutting time (mainly being to change plate to produce the time of qualified printed matter) so greatly, printing process was shortened in 5 minutes by about 15 minutes non-cutting time, also be more prone to simultaneously produce color printed matter true to nature, productivity ratio and product quality all are improved.
The ink amount supply process relates to following several respects: ink-covered area China ink amount is regulated, whole China ink amount is regulated and ink-water balance (glue seal).Go out the China ink amount by ink foundation roller corner size adjustment integral body, regulate little ink-covered area China ink amount by regulating each regional area gap length of ink roller, whole China ink amount is regulated and has been guaranteed correctly duplicating of printing image whole image contrast and tone, because it is different that the printing image distributes on the whole space of a whole page, each zone is also different to the demand of quantity of ink, therefore, along the ink roller axis direction ink foundation roller is divided into some little ink-covered areas, the China ink amount difference that different ink-covered areas is sent is to satisfy the different demands of each regional area of image to the China ink amount.Ink foundation roller corner size is regulated by servomotor, precision can reach 1 degree, little ink-covered area gap length is realized by the motion of minitype motor driving mechanical part, the conventional machinery parts have eccentric wheel, linkage and parallel movable block etc., displacement detects and feedback by potentiometer, and precision reaches 0.01mm at present.
Main ink amount supply control mode is to adopt the computer expansion board clamping at present, by integrated circuit board the bottom execution unit is controlled.This mode system flexibility is little, is not easy to expand combination, and system's formation and line are also complicated, are not easy to installation and maintenance.Adopt at present potentiometer that mechanical location is detected and feed back, potentiometer directly contacts with mechanical moving element, and signal is analog quantity, and also needing to carry out the AD conversion could controlled system accept, and reliability and precision are all low.
Summary of the invention
The object of the invention provides a kind of printing machine ink amount supply that adopts computer and automatic electronic control technology that ink amount supply process in the printing machine course of work is accurately controlled and controls control system automatically, it is the upgrading of the applicant having been authorized utility model patent " Electronic Control in the automatic control of printing machine mass colour ", it is more accurately easy to be quick that the black amount in ink-covered area is regulated, and the while can be united other control functions of printing machine such as ink foundation roller corner size adjustment (adjusting of whole China ink amount) and ink-water balance (glue seal) adjusting and be reached the accurately purpose of control of printing ink quantity supply process.
In order to reach above-mentioned target, the present invention is by the following technical solutions: printing machine ink amount supply automatic control system, it is characterized in that being provided with and contain the computer of controlling software and comprise the centralized Control layer, the exchanges data layer, carry out the sandwich construction embedded control system of key-course, wherein, the centralized Control layer is a central control unit, adopt ARM7 or ARM9 core processor and UCOSII embedded real-time multi-task operating system, be provided with the Ethernet interface that carries out communication with computer and external network, the order of receiving computer and control centre, system is controlled, give computer and control centre with the feedback information of system simultaneously, data exchange layer and execution key-course are controlled and monitored by 485 EBIs; The exchanges data layer is a communication unit, is provided with two independent 485 EBIs, is used for the data information exchange between centralized Control layer and the execution key-course; Carrying out key-course is the ink knife driver element, control information by 485 buses and exchanges data layer communication unit receiving computer and centralized Control layer central control unit, mechanical execution unit position is accurately controlled, and fed back self working state in real time; Every ink knife drive plate is made up of some driver modules, the processor of ink knife driver module receives through the computer of exchanges data layer communication board transmission and the control information of central control unit by 485 bus driving circuits, after control information handled, by the drive circuit drive motors, the ink knife mechanical movement of driven by motor ink-covered area realizes ink-covered area China ink amount control.
The centralized Control floor is provided with 8 road light and isolates input, output interface, is used for jointly controlling with the printing machine other system; Each driver module of carrying out key-course has independent controller, control an ink-covered area machinery execution unit, the shared one group of power supply of all driver modules on the same ink knife drive plate, adopt reducing motor to drive mechanical execution unit motion, detect the position and the direction of motor rotation axis by code device signal, thereby mechanical execution unit is accurately located.Have only grid line to connect between computer and the sandwich construction embedded control system, inner each key-course of sandwich construction embedded control system all adopts the bus mode line, and has only a pair of power line and pair of data lines.
Advantage of the present invention and beneficial effect:
1, with the control computer proprietary control software is installed, can be realized remote monitoring and diagnosis maintenance, can realize each key-course program of remote update sandwich construction embedded system by internet.
2, system can expand combination according to printing machine ink fountain quantity and ink-covered area quantity, is fit to the printing machine of various models.
