System and method for diagnosing state of FOCKE packaging machine tobacco bale group input unit

Abstract

The invention discloses a system and method for diagnosing the state of an FOCKE packaging machine tobacco bale group input unit. The system is characterized in that a PLC controller is respectively connected with a computer, a digital quantity input module, an analog quantity input module, an ELAU servo driving system and a 413 packaging machine; the digital quantity input module is respectively connected with a zero position sensor I, a zero position sensor II and a zero position sensor III; and the analog quantity input module is connected with a main encoder. The method comprises the following steps of starting and detecting whether a 413 packaging machine inlet system works normally or not, and starting a diagnosis process after abnormity; comparing a mechanical zero position with a zero position electrical angle and adjusting to be consistent; detecting the state of a packet missing detector, and ensuring that the state is normal; and detecting whether a turnover station motor controller, a tobacco bale extractor motor controller, a tobacco bale conveying motor controller and a tobacco group conveying motor controller are synchronous or not, and synchronizing when not synchronous. According to the device and the method, the fault detection of the FOCKE 413 packaging machine tobacco bale input unit can be quickly and effectively carried out.

Description

technical field [0001] The invention belongs to the technical field of cigarette equipment, and in particular relates to a system and a method for diagnosing the state of an input unit of a FOCKE packer cigarette pack group. Background technique [0002] FOCKE 413 packaging machine completes the box and box transparent paper packaging function of the FXS packaging unit. The structure of the entrance unit is relatively complicated. Qualified cigarette packs are extracted from the upstream machine, and after turning over, they are combined into a two-layer 10-box cigarette pack group. And then sent to the subsequent station. There are four servo motors to drive the belt and mechanical parts to complete various functions in the process from a single cigarette pack to the cigarette pack forming process, which are the overturning station motor, the cigarette pack extractor motor, the cigarette pack conveyor belt motor and the cigarette pack conveyor belt The motor and the whole ...

AI Technical Summary

Problems solved by technology

However, during the operation of the equipment, due to various factors, the input unit of the cigarette packs is likely to be uncoordinated, resulting in the servo drive failure of the input device at the entrance of 413, failure-free removal of the cigarette packs and the carton label paper on the follow-up station Inspection, self-inspection and other failures cause disorder in the input system of cigarette packs and seriously affect the efficiency of equipment

However, the slight misalignment is not obvious mechanically, and the parameter setting of the electric cam is also difficult to reflect

This has resulted in a wide range of troubleshooting for this type of fault, which is difficult to deal with, takes a long time, and is even difficult to fundamentally solve this type of fault.
