Abstract

The invention discloses an electronic alignment system, which comprises a sheet printed matter, and is characterized by also comprising a paper feeding roll, a rubber roll, a front-guide sensor, a side-guide sensor, a paper feeding roll driving device, a side-guide driving device, a front-guide servo controller, a side-guide servo driving controller and a connecting plate. The device directly detects positioning marks or edges printed on the sheet printed matter through the sensors, and feeds the detected signals to the servo controller, and the servo controller controls the servo device to perform fixed-position conveying and error correction on the sheet printed matter to position the single-paper printed matter. The electronic alignment system has the advantages that: the marks on the printed matter are directly detected by the sensors for positioning, and the positioning precision is high; and the paper feeding roll controls the sheet printed matter through an operating side paper feeding roll and a transmission side paper feeding roll so as to overcome errors of the sheet printed matter on the operating side and the transmission side caused by errors of a conveying platform when the conveying platform conveys the sheet printed matter.

Description

(1) Technical field: [0001] The invention is suitable for printing machines, especially for an electronic registration system and working method of sheet-shaped printed matter of printing machines. (two) background technology: [0002] With the increasingly fierce market competition, improving production efficiency and product quality is one of the main ways for printers to win the competition, and improving product precision is an effective way to improve quality. In the processing of sheet-fed printed products, before the sheet-fed printed products enter the processing station, it is necessary to adjust the sheet-fed printed products in the paper-feeding direction (paper running direction) and left-right direction (perpendicular to the paper running direction). To ensure that the paper is registered with the previous process during the printing process. The existing paper registration method is carried out through the direction of the mechanical front gauge and side gauge...
