Ultrasonic double-sheet control system based on Arduino software and hardware platform

Abstract

The invention discloses an ultrasonic double-sheet control system based on an Arduino software and hardware platform, and relates to the technical field of detection of an offset printing press. The ultrasonic double-sheet control system comprises an ultrasonic double-sheet detection sensor and a double-sheet logic controller, wherein the ultrasonic double-sheet detection sensor is used for detecting no-sheet, single-sheet and double-sheet signals; the double-sheet logic controller adopts Arduino UNO R3 as a main control board, utilizes software programming to achieve a counting function, andoutputs an alarm signal to realize double-sheet alarm and stop when the counter value overflows. The ultrasonic double-sheet detection control system minimizes the omission rate of double or multiplesheets, effectively avoids the equipment safety and blank sheet quality problems caused by detection omission of double sheets, and obtains better economic benefits. The control system is relatively independent to meet the versatility in different kinds of sheet-fed offset printing presses, and can be easily promoted and applied to any sheet-fed offset printing press only with simple signal interaction.

Description

technical field [0001] The invention belongs to the technical field of offset printing machine detection, in particular to an ultrasonic double-sheet control system based on an Arduino software and hardware platform. Background technique [0002] In recent years, as far as the development of sheet-fed offset press technology is concerned, the mechanical technology is relatively stable, and most manufacturers focus on the improvement of intelligent and automatic control. As a result, the running speed of the printing press and the stability of product quality have also been rapidly improved. As an essential part of the sheet-fed offset printing machine, the control technology of the sheet-fed feeder has also been greatly improved, especially the double-sheet detection system, and its detection method has also developed from a single mechanical type to a Mechanical, photoelectric, capacitive, ultrasonic and other combined use modes. [0003] During the operation of the paper...

Problems solved by technology

The early domestic offset printing machines used a single mechanical double-sheet detection method, which had many problems such as low sensitivity, high missed detection rate, and easy damage to the surface of the substrate when touching it.
