Abstract

The utility model discloses an electronic shaft control system for an imprinter, comprising a host which is under the monitoring of the user and collects chromatography error data from each extension workstations. A multicolor liquid crystal touch screen is hung outside the host and is connected with a plurality of extension workstations through CAN buses; an extension workstation is provided with a module with the function of signal processing and motor phase adjusting and the module is connected to a servo motor and a detection light eye; the detection light eye serves as a sensor and is used to detect the chromatography error of a printing and the servo motor is an actuator for adjusting the electronic shaft phase offset. Adopting advance technology and with a reasonably designed structure, the utility model is highly automatized and has reliable working performance. The utility model is easy to use and to maintain and can save energy.

Description

Printing machine electronical line shaft control system

Technical field

The utility model relates to a kind of control system that is used for intaglio press, flexible printing machine and offset press printing machine, particularly a kind of printing machine electronical line shaft control system.

Background technology

In recent years, very big variation has taken place in printing machine market both at home and abroad, because the production of globalization competition, the printing machine user has turned to outlet and high-end market gradually, to chase higher profit, therefore printing equipment is had higher requirement.At present external print line had trended towards using the printing equipment that has electronical line shaft already gradually, the European market has begun to eliminate traditional major axis printing machine, wherein representative manufacturer is a Heidelberg, Germany company, the fashionable whole world of printing machine that the said firm adopts the electronical line shaft control system of German power Xerox to produce has obtained splendid social repercussion and economic benefit.Compared with the above case, homemade printer technology level does not also reach middle and high end user's demand, and still being in traditional major axis printing machine is main production model, and the development work of novel electron axle printing machine also is in the starting stage.Along with the import of novel electron axle printing machine and the application of new technologies and methods, equipment purchasing and maintenance cost are corresponding to be increased substantially, and fault rate constantly increases, and maintenance and repair work is also owing to the labyrinth and the The application of new technique of equipment become difficult more.

The utility model content

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of technical indicator can satisfy the high-end user demand, and control technology advanced person is rational in infrastructure, easy and simple to handle, reliable operation, printing machine electronical line shaft control system easy to maintenance.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of printing machine electronical line shaft control system, it is characterized in that: it comprises a main frame that is used to gather each extension set work station chromatography error data and supplies user monitoring, the plug-in chromatic colour liquid crystal touch screen of described main frame, and be connected with a plurality of extension set work stations by the CAN bus, the extension set work station is equipped with the signal processing and motor phase is adjusted functional module, and with servomotor with detect the light eye and be connected, detect the light eye as sensor, be used to detect the chromatography error of printing, servomotor is for adjusting the executing agency of electronical line shaft phase deviation.

The utility model compared with prior art has the following advantages: the utility model adopts digital signal processor (DSP) and extensive gate array (FPGA), has guaranteed high speed that data are handled and anti-interference, and leaves very big leeway for expanding again of system; Adopt embedded chip to constitute embedded system, adopt advanced CAN bus to build the control network, this framework form makes data highly-efficient treatment, flexible, has guaranteed the expansion of the efficient of control system and printing color bits; The utility model control system adopts DSP56803 as the execution chip of adjusting printing deviation, and this chip is the instruction cycle of 25ns, cooperates high performance PWM output circuit, adopts advanced fuzzy control theory, and the print speed printing speed that makes system's adaptation is greater than 300m/s; The system deviation measurement function is finished by large-scale programmable logic array (FPGA), and the measuring-signal of this chip can reach 10ns from being input to output, has guaranteed the demand of system fully; Under control of the present utility model, the version roller only need arbitrarily be packed printing element into and do not needed to recover " zero-bit " again, thereby servomotor can forward the version roller to " zero-bit " automatically realize truly the pre-alignment of high accuracy, enter the register control printing state subsequently, make whole process become simply, quick; The utility model has guaranteed not have the use of axle (electronical line shaft) drive technology, each unit both can have been linked to be printed, but also individual operation, can realize a unit when printing, another unit prints preceding preparation, has reduced non-cutting time, made things convenient for the combination of machine, improve the printing precision of machine, shortened debug time, strengthened the adaptive capacity of equipment.Simultaneously can save the high-power driving motor, thereby save the energy.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in Figure 1, the utility model comprises a main frame that is used to gather each extension set work station chromatography error data and supplies user monitoring, the plug-in chromatic colour liquid crystal touch screen of described main frame, and be connected with a plurality of extension set work stations by the CAN bus, the extension set work station is provided with the signal processing and motor phase is adjusted functional module, and with servomotor with detect the light eye and be connected, detect the light eye as sensor, be used to detect the chromatography error of printing, servomotor is for adjusting the executing agency of electronical line shaft phase deviation.

Described main frame is equipped with DSP embedded 56803 chips, and dsp chip is as the execution chip of adjusting printing deviation.

During the utility model work, utilize and detect the measurement of light eye, gather actual print marker spacing signal, the extension set work station is handled this real data, obtain the actual print marker spacing distance of reflection phase deviation, and send the phase place adjustment to servomotor and instruct, control each color bits servomotor running, the phase deviation of electronical line shaft is adjusted, and upload the main frame monitoring by the CAN bus.
