Description

Circular screen printer multi-shaft motion control system based on the CAN bus

Technical field

The utility model belongs to technical field of textile printing, is specifically related to a kind of circular screen printer multi-shaft motion control system based on the CAN bus.

Background technology

Textile printing and dyeing industry occupies bigger ratio in the Chinese national economy income.The height of textile class depends on dyeing and finishing post processing level to a great extent.As the key equipment of finishing process in printing and dye-ing, circular screen printer becomes the main flow process equipment of present stamp industry with its exclusive advantage, and is able to extensive use.Country lists the technological transformation of dyeing in one of industry of textile industry emphasis support in recent years, transformation by decades, the printing and dyeing industry of China has been made significant headway and has been developed, but on key technology, still exist bigger gap with external advanced level, not high as the level of informatization, the various piece self-organizing system forms " information island ".Along with the demand of development of market economy and international market, to the quality of textile, designs and varieties, repdocutbility etc. require more and more higher, and printing and dyeing are as the important process stage of textile, and the total quality of textile is had important effect.Must improve the high technology content of printing equipment for this reason, improve its automaticity.Domestic novel circular screen printer is in the development stage always, and Cheng Shu product is introduced to the market without comparison.Though import circular screen printer performance is good, extremely expensive, cause many stamps producer to be hung back.This situation has limited the competitiveness of the high-grade stamp product of China in the international market greatly, has hindered the development of numerous domestic stamp producer on high-grade ROTARY SCREAM PRINTING fabric.

Summary of the invention

The purpose of this utility model provides a kind of circular screen printer multi-shaft motion control system based on the CAN bus, and it is not high to have solved existing control system automaticity, expensive problem.

The technical scheme that the utility model adopted is, a kind of circular screen printer multi-shaft motion control system based on the CAN bus, comprise the CPU module and the CAN bus interface module that are connected by the CAN bus, the other end of CAN bus interface module is connected with two or more slave station control modules that is in series, be connected with the operational module that two or more are in series on each slave station control module, be connected with a printing cell on each operational module respectively, two or more operational modules are also connected with display module.

Characteristics of the present utility model are that also CPU module wherein adopts the special risc processor 80960SB of the English that has FPU Float Point Unit, and clock frequency is 16MHz, and CU201/E is 20MHz.

The utility model is based on the circular screen printer multi-shaft motion control system of CAN bus, replace traditional mechanical cam and gear with multi-axis motion controller, brought huge flexibility to the Machine Design manufacturing, the electricity consumption submode is realized coordinate synchronization between the mechanical movement axle.Set up a digital communications network, thereby effective coordination, each motion process synchronously realizes high-precision multiaxial motion control based on the real-time high-efficiency of CAN bus.In addition, all often control nodes of the control system in past are all concentrated and are arranged on the big control panel, and this has often brought very big ineffective activity to system, if certain vitals breaks down and will cause the significant impact of system on the control panel.Have characteristics such as high-performance, high reliability, real-time are good based on the control network of CAN bus and will make stable synchronous operation more flexibly between each control node.Each servo-driver of native system has all designed the CAN interface, compares with traditional control network based on the CAN bussing technique, need not other conversion equipments, has omitted otherwise designed CAN node.The mode of fieldbus is controlled servo-drive system, the control of completing place, speed, commentaries on classics distance simultaneously, can not only satisfy the motion control requirement of modern automation better, and it is simpler and more direct, reliable aspect the hardware connection, its formed complete servo-drive, make driving, I/O, HMI in the consolidated network system, have characteristics such as how main ability, information guiding communication, information command priority and reliability.
