A Numerical Control System of Can Printing Machine Based on Digital Motion Controller

Abstract

A digital motion controller-based numerical control system for printing can machines, including: a Windows-based man-machine communication touch screen operation control module; a digital motion controller; a motion execution module; a reducer module; and a Windows-based man-machine communication touch screen operation The control module and the digital motion controller are connected through an Ethernet network cable, and the digital motion controller and its I / O sub-board are directly connected to the I / O signal connection terminal of the motion execution module, that is, the AC servo motor; the digital motion controller is connected to the motion controller through the Ethernet bus. The execution module is connected to the servo AC motor; the digital motion controller is connected to four AC servo motors to form a double closed-loop motion control system. The system structure of the present invention is simple, each component is relatively independent, part of the hardware can be directly purchased from commercially available products as components, not only the performance can be compared with it, the cost is reduced, but also the assembly, use and upgrade are extremely simple, and can be extended to pop cans in batches Printing production line and similar iron printing production line.

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
