Online detection device for filter capsule filter stick

Abstract

The invention discloses an online detection device for a filter capsule filter stick, and relates to the field of filter capsule filter stick detection. The online detection device for the filter capsule filter stick comprises an image acquisition module, a control module and a touch display screen, wherein the image acquisition module comprises a detection channel, a shell and a cover plate, oneside of the detection channel is provided with an industrial camera, an optical lens and a plane mirror, the other side of the detection channel is provided with a light source, the image acquisitionmodule collects an image of the to-be-detected filter capsule filter stick through the industrial camera and transmits the image to the control module after the image is subjected to primary treatment, the control module processes the image acquired by the image acquisition module and judges whether the filter capsule filter stick has the defects of missing, adhesion and displacement or not, the control module sends a corresponding culling signal to a filter stick forming unit control system according to a judgment result, and the touch display screen is used for displaying operation information of the device and carrying out parameter setting. According to the online detection device, the defect detection accuracy of the filter capsule filter stick is improved, unqualified products can beprevented from flowing into a rolling and packaging link from the source, material consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of detection of pop-bead filter sticks, in particular to an on-line detection device for pop-bead filter sticks. Background technique [0002] In recent years, with the gradual upgrading of consumer demand, adding explosive beads to filter rods can not only reduce harm and reduce coke, but also further enhance the richness of cigarette products. Major tobacco factories have launched a variety of products with blasting bead filter rods, and quality problems such as missing, connecting beads, shifting and damage have occurred frequently, which will definitely bring consumers Reduced experience may even cause complaints; if the quality inspection of the filter rods is carried out during the forming stage of the pop-bead filter rods, the unqualified products are eliminated, and the defective filter rods are prevented from entering the cigarette manufacturing process, which will greatly improve the quality and consumption ...

Problems solved by technology

The main problem is that the light source and industrial camera adopt a non-integral design, and they need to be adjusted to ensure that they are on the same vertical plane during installation. Due to the gravity of the filter rod itself, the structural parts that fix the light source will inevitably be glued at the moment of starting and stopping. Therefore, it will affect the measurement; between the strip breaker on the original unit and the cutting inlet, it is necessary to add related fixed structural parts separately, and the distance between the camera and the filter rod is generally 200-500mm, which will have a certain impact on the normal operation of the operator and will not Beautiful; due to the open design, in order to avoid the impact of external light sources on the detection, there is a high requirement for the brightness of the light source, and the heat dissipation design of the light source needs to be considered. In addition, the light of the light source installed separately is emitted from the bottom to the top. eye damage
