16-way Modular Adjacent Mutual Control Configuration Paper Break Detection Control Method for Newspaper Offset Press

Abstract

The invention discloses a 16-way modular adjacent mutual control configuration paper break detection and control method for a newspaper web offset printing machine. Firstly, a basic module is constructed, which includes a microcomputer PC and 16 pairs of I / O input and output ports are programmable logic controller PLC, 16 pairs of input and output ports are respectively connected to 16-channel paper-breaking detection heads and 16-channel paper cutter drive system, and the 16 detection heads and The 16 paper cutters can drive and output arbitrary configurations; secondly, multiple basic modules are connected and communicated through Ethernet, and each module sends its own local 16-way paper break detection head input signal to the left and right adjacent modules at the same time, Simultaneously receive input signals from the 16-way paper-breaking detection head from the left and right adjacent modules; thirdly, the 16-way paper-breaking knife output of each module can be freely configured by the microcomputer keyboard or screen to be input from the left neighbor, itself A total of 48 detection head signals with the right neighbor can be driven arbitrarily.

Description

technical field [0001] The invention relates to a method for detecting paper breakage of a newspaper roll-fed offset rotary press, in particular to a method for detecting and controlling paper breakage of a newspaper roll-fed offset rotary machine in a modular mutual control configuration. Background technique [0002] The paper break detection system is an essential protection system for newspaper web offset printing presses. Its function is: once the paper breaks at a certain point in the printing machine's paper path, the corresponding paper break detection head will immediately send a signal to stop the machine; It also drives the paper cutter configured at the entrance of the corresponding paper tape to cut off the paper supply, so as to prevent the continuous paper tape from continuing to enter the printing cylinder and cause winding, which will eventually crush the rubber of the printing roller or even damage the machine parts. [0003] Due to the increasing number of...

The disadvantage is: the above-mentioned versatility is based on the detection and drive channel system with a relatively large margin

When applied to small units, more redundant detection and driving channels will lead to excess resources and increase costs, and even so, when encountering larger or super-large printing units, there may still be insufficient channels, and it is still inseparable Targeted special design
