A printing machine fault online detection device and detection method

Abstract

The invention discloses an on-line detection device for a printing machine breakdown and a detection method. The on-line detection device for the printing machine comprises an electronic detector, the electronic detector comprises a CCD camera, an external trigger and an analysis and processing module are connected with the CCD camera through data transmission lines respectively, the external trigger is installed at the position of a paper aligning device of the printing machine, detection identifications are further included, and the detection identifications are arranged at a seaming and a tail end of a forme of the printing machine. The on-line detection device for the printing machine breakdown and the detection method utilize detection identifications to dynamically acquire data of the operation status of the printing machine, therefore a basis for detecting the printing machine breakdown is provided; traditional printing machine breakdown detection is substituted to some extent, the degree of automation is high and the precision is high; the printing machine breakdown is ascertained rapidly, so that time for the printing machine adjustment and breakdown maintenance is saved a lot and the service efficiency of the printing machine is improved.

Description

technical field [0001] The invention belongs to the technical field of debugging and detection of printing machine equipment, and relates to an online fault detection device of a printing machine, and also relates to a detection method using the detection device. Background technique [0002] As the speed of printing equipment increases, if the printing machine breaks down, it will cause a large number of defective printed products and stop for maintenance, which seriously affects the printing production efficiency and economic benefits. Traditional printing machine fault detection methods mainly adopt repeated tests, shut down for maintenance, start-up trial printing, etc., and rely on the experience of maintenance personnel to make judgments. The fault detection process takes a long time, the accuracy is low, and the downtime is long. Development and requirements are extremely incompatible. [0003] The operating mechanism and operating status of the printing process are ...
