Straw Defective Product Inspection Machine with Automatic Labeling System

Straw Defective Product Detection And Rejection Equipment

System configurations

Sample

Straw is a drinking tool equipped with many restaurants and beverages, and it is also an item that directly contacts the oral cavity. Therefore, many food production and processing factories have high requirements on the quality of products, such as the appearance of straws. Color, black spots, stains, impurities, hair, etc. Problems will affect consumers' experience of use, so it is of great significance to eliminate defective products before the products leave the factory.

System features

The entire inspection system is assembled into the straw lamination equipment in a modular way, and integrates the hardware and inspection software of the vision system. The maximum inspection speed is 900 pieces/min.The labeling machine is connected to the labeling machine for automatic labeling, and the back-end manual intervention is processed. After the finished product is detected, the counting and statistical function can be realized.

The equipment can operate 7*24 hours a day, greatly improving production efficiency. Pipette detection device

Each device is equipped with 3 sets of high-pixel industrial cameras to conduct a comprehensive defect inspection on the appearance of the straw products after film packaging. After the system collects the sample images, the image processing software is compared with the standardized sample to determine the good and bad products. The software will open the sample comparison standard, and the production personnel at the customer site can control the comparison accuracy and select the most suitable accuracy standard for their own production conditions, thereby controlling the defect rate.

The installation position of the detection module is shown as follows:

3. Detection details: After preliminary communication between the two parties, comprehensively considering the complexity and feasibility of the system,

Observation and inspection requirements and confirmation of indicators (see Annex 1: Inspection Standards for Defective Paper Straws):

note:

1. In actual detection, due to the influence of the critical fluctuation state of the data of some detection items, it will lead to a certain probability.

If the product is falsely detected, it can be adjusted through the parameter setting of the system software to achieve the actual effect.

2. Black spots, stains, impurities, hair and other defect features (different colors), the gray value contrast difference corresponding to the detection index should be greater than 40 (it can be understood as: placing the sample at an arm distance, about 30cm or more, can be Defect features seen by visual inspection) can be effectively detected. If the sample has transparent oil stains or light-colored black spots, and the gray value contrast difference is low (below 40), the detection effect cannot be achieved.

3. The horizontal direction of the straw belt is the blind area of the camera's field of view, so the defect features at this position cannot collect images for input.

Line recognition, but this position is relatively narrow, the vertical distance is about 1.0mm.
