Packaging machine emergency protection switch tripping fault diagnosis system

Abstract

The invention discloses a packaging machine emergency protection switch tripping fault diagnosis system. The packaging machine emergency protection switch tripping fault diagnosis system comprises a monitoring mechanism for monitoring whether any power supply branch has a DC short circuit fault or not, a packaging machine emergency stop switch group S, a protective cover protection switch group 2S, a main controller and a display screen; the monitoring mechanism includes sub-monitoring components arranged in one-to-one correspondence with the power supply branches, and each sub-monitoring component includes a sub-signal processor and a current sensor; the current sensors in the sub-monitoring components are connected to the sub-signal processors, the sub-signal processors are connected with the main controller, and each emergency stop switch and each safety protection switch are respectively connected to the input end of the main controller in series; and the main controller is connected with the display screen. The packaging machine emergency protection switch tripping fault diagnosis system can directly indicate the specific position and function name information of the power supply branch which causes packaging machine emergency protection switch tripping, is provided with a faulty protective cover and emergency stop switch and causes circuit breaker and hard box machine tripping on the display screen, and electrical maintenance personnel is prevented from checking term by term.

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 ...

AI Technical Summary

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
