A fault diagnosis system for the tripping of the emergency protection switch of a packaging machine

Abstract

The invention discloses a tripping fault diagnosis system for an emergency protection switch of a packaging machine, which includes a monitoring mechanism for monitoring whether a DC short-circuit fault occurs in any power supply branch, an S group of emergency stop switches in the packaging machine, and a 2S group of protective cover switches , a main controller, and a display screen; the monitoring mechanism includes a sub-monitoring component that is set in one-to-one correspondence with the power supply branch, and the sub-monitoring component includes a sub-signal processor and a current sensor; the current sensor in the sub-monitoring component is connected to the sub-signal processor, The sub-signal processors are respectively connected with the main controller, and each emergency stop switch and safety protection switch are respectively connected in series with the input end of the main controller; the main controller is connected with the display screen. The present invention can directly indicate on the display screen what causes the emergency protection switch of the packaging machine to trip, the existing fault protection cover, emergency stop switch, and the specific location and function name information of the power supply branch that causes the trip of the circuit breaker and hard box machine, avoiding electrical The maintenance personnel will check each item one by one.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a fault diagnosis system for tripping of an emergency protection switch of a packaging machine. Background technique [0002] GD packaging equipment is an 8000-type packaging unit imported from Italian G.D company in my country's tobacco industry. Due to its high production speed and effective operation rate, this machine has become an ideal model for connecting high-speed cigarette machines in the tobacco industry. But there are still some deficiencies in some local control parts. [0003] GD packaging equipment is equipped with an emergency protection switch. The power supply supplies power to all motors on the production line through the emergency protection switch. In an emergency, the power supply to all motors on the production line is cut off, thereby interrupting the operation of the machine and ensuring the safety of the machine and operators. [0004] The root ...

Problems solved by technology

However, there are many branch circuits in each institution, and the instantaneous current of any branch circuit is too large, which can cause the circuit breaker in the controlled area to be overloaded, resulting in emergency protection switch

After these problems occur, electrical maintenance personnel must check item by item, which increases a lot of workload and greatly reduces work efficiency
