Abstract

The invention provides a GD packaging machine safety interlocking fault diagnosis method and system, and the method comprises the steps: enabling a normally open contact and a normally closed contact corresponding to each safety switch of a packaging unit protective cover to be connected in series through a safety interlocking line, and enabling the normally open contact and the normally closed contact to be in signal connection with an OPC display screen of a packaging machine. And a PLC (Programmable Logic Controller) is arranged, and the input end of the PLC is independently arranged to be connected with a signal line between each normally-closed contact. And an input port of the PLC is numbered, and the number of the input port corresponds to each normally closed contact. And when the packaging machine operates, the voltage of the input port of the PLC is monitored in real time circularly according to the number of the input port so as to judge whether the corresponding normally-closed contact has a fault or not. The intelligent monitoring level of production of the GD packaging machine can be improved, and the production efficiency of the GD packaging machine is improved.

Description

technical field [0001] The invention relates to the technical field of monitoring of cigarette packaging machines, in particular to a method and system for diagnosing safety interlock failures of GD packaging machines. Background technique [0002] GD packaging equipment is an 8000-type packaging unit imported by my country's tobacco industry from G.D. Italy. The machine is equipped with a movable safety interlocking guard, which is used to protect the personal safety of the operator when the machine is running. When the machine is opened, the machine will stop immediately. Each safety switch will have a normally open contact and a normally closed contact. For the opening operation of each guard, that is, the action of the normally open contact, the OPC will display an indication that the corresponding safety guard is opened. However, the fault of the normally closed contact only prompts the safety protection chain fault information. GDX2 and GDX1 respectively contain 21 and...
