Can printing machine numerical-control system based on digital motion controller

Abstract

The invention relates to a can printing machine numerical-control system based on a digital motion controller, and the can printing machine numerical-control system comprises a human-machine communication touch screen operation control module based on a windows platform, a digital motion controller, a motion actuation module and a reducer module, wherein the human-machine communication touch screen operation control module based on the windows platform is connected with the digital motion controller through an Ethernet network cable, and the digital motion controller and an input / output (I / O) sub-board of the digital motion controller are directly connected with an I / O signal connection terminal of the motion actuation module, i.e. an alternative-current servo motor; the digital motion controller is connected with the motion actuation module i.e. the alternative-current servo motor through an Ethernet bus; and the digital motion controller is connected with four alternative-current servo motors to form a double-closed-loop motion control system. The system is simple in structure, each constitutional part is relatively independent, partial hardware can be directly purchased in the market to be used as the constitutional part, not only can the performance be comparable and the cost be reduced, but also simplicity in assembling, application and upgrading can be realized, and the tank printing machine numerical-control system can be mass popularized to a pop can printing production line and similar iron production lines.

Description

technical field [0001] The invention relates to a motion control system in the technical field of industrial control automation, in particular to a motion control system for shaftless printing of pop cans based on a digital motion controller. Background technique [0002] The transmission of the current can printing production line mainly relies on mechanical components such as gears and shafts fixed on the production machine to transmit the power of the main shaft motor to each printing unit. Due to the long distance and various mechanical transmission mechanisms in the power transmission, the entire The transmission chain is vividly called the mechanical long axis. The shaftless printing system for cans mentioned in this patent actually replaces the complicated and traditional mechanically driven long shaft with the electronic long shaft (virtual) driven by digital servo. [0003] The traditional mechanical long-axis transmission mode is mainly characterized by a wide ran...

Problems solved by technology

[0003] The traditional mechanical long-axis transmission mode is mainly characterized by a wide range of speed adjustment of the gearbox and high precision requirements, but it also has many disadvantages: 1) high manufacturing cost, difficult installation and maintenance; 2) printing accuracy and printing speed are affected by the mechanical structure 3) If one axis is disturbed, it will cause the fluctuation of the entire mechanical axis; 4) When the specifications of the printed products are different, the mechanical parts need to be replaced, and the flexibility is poor
