Label paper inversion detection device and detection method thereof

Abstract

The invention discloses a label paper inversion detection device and a detection method thereof. The label paper inversion detection device comprises a supporting assembly and a detection assembly, wherein a first fixing block and a second fixing block in the supporting assembly slide left and right through a sliding assembly, and the detection assembly comprises an optical fiber sensor, a signal amplifier and an absolute value encoder. One side of the signal amplifier is connected with the optical fiber sensor, the received luminous flux is in direct proportion to the numerical value of the signal amplifier, and a first channel of the signal amplifier is used for outputting a label paper inversion signal and transmitting the signal to a data processing device. The absolute value encoder is used for recording the phase of the label paper on a positioning platform in real time. The data processing device is used for outputting a rejection signal and a shutdown signal to an original machine controller. According to the label paper inversion detection device and the detection method thereof, all positions of the detection assembly are adjusted, so that the detection effect is better; and whether label paper is inverted or not and whether the optical fiber sensor is dirty or not are detected through the detection assembly, the detection precision is higher, and manual operation is avoided.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a label paper inversion detection device and a detection method thereof. Background technique [0002] In the process of tobacco processing, high-speed packaging of soft packs is required, mainly through the control system in the original packaging equipment (hereinafter referred to as the original machine control), the label paper is first glued, and then attached to the packs one by one superior; [0003] Traditional label paper conveying and folding methods are mainly divided into pre-cut type and roll type. When using pre-cut label paper, in order to achieve better packaging folding effect of label paper, the edge of the label paper is pre-cut in advance, but in In the folding of trademark packaging, due to factors such as incoming materials and human misoperation, there will inevitably be the phenomenon of trademark paper being inverted. At present, traditional packaging e...

[0003] Traditional label paper conveying and folding methods are mainly divided into pre-cut type and roll type. When using pre-cut label paper, in order to achieve better packaging folding effect of label paper, the edge of the label paper is pre-cut in advance, but in In the folding of trademark packaging, due to factors such as incoming materials and human misoperation, there will inevitably be the phenomenon of trademark paper being inverted. At present, traditional packaging equipment mainly relies on visual inspection devices to check the appearance quality of cigarette packs. However, in actual production, cigarette packs Appearance quality inspection cannot accurately and reliably identify inverted cigarette packs, and the inspection space is small, and the appearance quality inspection device cannot be better arranged according to actual use, resulting in inverted cigarette packs flowing into subsequent processes, and this quality defect cannot be avoided by manual judgment , resulting in serious quality accidents, the market feedback rate is high
