Synchronous Control Method of Print Head and Cylinder in Nano Direct Platesetter

Abstract

The invention relates to a system and a method for synchronously controlling a print head and a roller in a nanometer computer to plate. The system comprises the print head and the roller, possesses a controller unit, a roller servo driver, a roller servo motor, a print-head servo driver, a print-head servo driver, a print-head servo motor and an encoder; the controller unit generates a cam table; a set of cam table parameters are stored for cooperating with a sheet material; a lifting point, in the cam table, of a printing apparatus along with a roller tail clamp is X; if the sheet material size is not changed and the print head is at an original position, the controller unit controls the roller to return to the roller zero position; the controller unit controls the print head to an assigned position; the cam table is started; and when the controller unit controls the roller, corresponding displacement is obtained through the cam table, and the print head executes motion along with a roller main shaft. The system realizes the function that the print head synchronously tracks roller motion, the system running safety is improved, relatively high processing precision and flexibility are provided, and production efficiency is substantially improved.

Description

Technical field [0001] The invention relates to a synchronous control technology for a plate making machine, in particular to a system and method for synchronous control of a print head and a cylinder in a nano direct plate making machine. Background technique [0002] During the printing process of the nano plate making machine, the print head device following the continuous rotation of the drum to produce corresponding displacement is the key to the whole system. Its performance plays a vital role in the quality, loss and production efficiency of plate imaging, and it is also the entire production line. One of the most complicated links in electrical control. Therefore, to improve the quality of printing, the stable operation of the equipment and safety are of the utmost importance. It is necessary to improve the performance of the overall control system. The existing nano direct plate making machine adopts a single movement mode when operating, and the rotation of the main sh...
