Embodiment Construction

[0029] Such as figure 1 The visual inspection system for the segment length of the composite filter rod shown has a detection drum, a rejecting drum, a transfer drum, and a filter rod collecting and conveying assembly that are sequentially connected to the smoke separating wheel of the filter rod forming machine. machine vision system.

[0030] The detection drum is composed of a detection drum shell, a spectroscope, a visual imaging diaphragm, and a high-light light source in the order from outside to inside; wherein, the spectroscope is close to the inside of the test drum shell, and the part of each spectroscope There are several through holes, and the inner side of each through hole is connected with a negative pressure air path, which is convenient for absorbing the filter rod.

[0031] The high-gloss light source can provide high-brightness illumination, and through the visual imaging diaphragm, the concentrated light source of the high-gloss light source can be turned ...

Abstract

The invention relates to a visual detecting system for composite filter rod section lengths. The system comprises such parts as a filter rod drum wheel module, a machine vision system, a filter rod collecting and conveying module and an industrial processor. The filter rod drum wheel module consists of a detecting drum wheel, an eliminating drum wheel and a transfer drum wheel. A main smoke separation wheel at the tail end of a composite filter rod forming unit is assembled with the detecting drum wheel, the eliminating drum wheel and the transfer drum wheel through a mechanical gear engagement mode for synchronous rotation. The detecting drum wheel consists of a detecting drum wheel outer shell, a light separation cover, a visual imaging diaphragm and a highlight light source from outsideto inside; and an air separation cover is arranged on the inner side of the eliminating drum wheel outer shell, communicates with a negative-pressure air distribution sleeve pipeline through one partof through holes, and communicates with a positive-pressure air distribution sleeve pipeline through the other part of through holes. The system can detect the length of each section of filter rods online, achieves high accuracy and consistency of measuring results, and can automatically sort and eliminate unqualified filter rods to achieve high detecting efficiency and low labor intensity.

Description

technical field [0001] The invention relates to a filter rod data detection and a sorting technology of qualified products and unqualified products. Background technique [0002] The ordinary filter rod is a filter section made of one material; the measurement of its length is very simple, just use a ruler to measure it directly. Composite filter rod is a kind of functional filter rod, which is an important product branch in the cigarette filter industry. Composite filter rod has filter segments made of two or more materials, and then spliced ​​and compounded according to the axial direction. Its total length The measurement method of the filter rod is as simple as the measurement method of the ordinary filter rod, and the two or more filter segments wrapped in the forming paper are invisible to the naked eye, and the length of each segment cannot be directly measured with a simple ruler. [0003] Domestic composite filter rod manufacturers mainly use microwave measuring in...
