Detection system of cigarette loose ends

Abstract

The invention discloses a cigarette empty end detection system, which comprises a power supply, a synchronization unit, a data acquisition unit, an analog-to-digital conversion unit, a main control unit, and a rejection unit; the output terminal of the synchronization unit and the input of the analog-to-digital conversion unit and the rejection control unit Both terminals are connected, the synchronization unit is used to provide a synchronous clock signal for the analog-to-digital conversion unit, the main control unit and the rejection control unit, the output terminal of the capacitive sensor is connected to the input terminal of the analog-to-digital conversion unit, and the output terminal of the analog-to-digital conversion unit The input end of the main control unit is connected, and the output end of the main control unit is connected with the rejecting unit; a kind of cigarette end detection system of the present invention adopts the capacitive sensor with good stability and can adapt to various complex environments as the detection device, The hardware circuit adopts programmable control FPGA as the main processing chip, which not only can meet the complex and changeable production environment of the tobacco factory, but also improves the rejection rate of problematic cigarettes and greatly improves the quality of the product.

Description

technical field [0001] The invention relates to a cigarette empty end detection system for a packaging machine, in particular to a cigarette empty end detection system. Background technique [0002] The detection and processing of cigarette empty ends by the cigarette packaging machine is mainly through a group of empty end detectors installed at the small package mold box. When the detector detects one or more empty end cigarettes in the mold box, the mold box will be changed The 20 cigarettes within will be removed from the production line, and the rejected cigarettes will be treated as waste cigarettes regardless of whether they are good or bad. At the same time, the packaging accessories of the cigarette pack will also be removed. A great waste is generated, which is not in line with today's production philosophy of improving quality and reducing consumption; [0003] At present, some domestic companies have launched a single cigarette detection and elimination system t...

Problems solved by technology

[0002] The cigarette packaging machine detects and processes the empty end of cigarettes mainly through a group of empty end detectors installed at the small package mold box. When the detector detects one or more empty end cigarettes in the mold box, the mold box is changed. The 20 cigarettes within will be removed from the production line, and the rejected cigarettes will be treated as waste cigarettes regardless of whether they are good or bad. At the same time, the packaging accessories of the cigarette pack will also be removed. A great waste is generated, which is not in line with today's production philosophy of improving quality and reducing consumption;

[0003] At present, some domestic companies have launched a single cigarette detection and elimination system to detect empty cigarettes. However, due to the late start in China, there is no mature technology and means, and there is a problem that the rate of proposal is not high. In the case of a large number of manual interventions , the rejection rate is generally below 60%, resulting in the problem of incomplete removal of problematic cigarettes and poor quality; at the same time, the rejection detection system is generally composed of photoelectric sensors, which have relatively high requirements for the environment, which leads to the adaptability and stability of the system Sex is not high
