Machine vision equipment for sorting of products in a box
Deep Learning is one of the branches of artificial intelligence that is increasingly present in automated manufacturing processes. Artificial vision based on Deep Learning offers a multitude of solutions to solve the most complex vision and classification challenges in a simple way.
This technique manages to analyse images in a very similar way to humans by training convolutional neural networks, an image segmentation system that quickly adapts to new samples without the need to reprogramme algorithms, just by re-training the system by introducing the images of these new categories to be added.
Among the most outstanding utilities of Deep Learning are:
- Product classification and identification
- Verification of the integrity of the product or packaging.
- Locating, counting and checking the correct placement of features, parts and products in their assembly
- Reading alphanumeric characters on complex surfaces such as transparent and soft bottles or labels with defects.
Therefore, machine vision based on Deep Learning offers solutions to problems that cannot be solved through traditional vision.
In certain food processes in the meat sector where food is processed in line, it is common that at the end of the cutting lines it is the operators who identify the products and decide which further processing line they should go to.
This task is tedious and costly and can be replaced by a trained vision system for automatic sorting of the products, which allows the automation of the following processes. AI-Sorter is an automatic product classification equipment in real time by Deep Learning. It is used to classify different product references or categories. The equipment allows the classification process to be automated, reducing the error rate and significantly increasing effectiveness.
At the same time as classifying, the system detects quality defects, as once the product category has been identified, a specific quality inspection algorithm is executed, being able to detect contamination and defects in the slaughtering process.
This automation of the classification process in real time is achieved by training a neural network from thousands of images. Images are introduced and labelled indicating the reference with which we want the system to identify the product. In other words, the more images the system receives, the more this neural network is trained, until the system “learns” to identify the different product categories on its own.
What are its advantages?
High inspection yields
No reprogramming of algorithms necessary for introduction of new product categoriess
Reduction in labour costs
- Product identification
- Quality sorting
- Detection of processing defects: bones, calves, cartilage..
The AI-Sorter equipment has an image capture system composed of high-resolution RGB matrix cameras and LED lighting system, which allow to adopt optimal conditions for in-line image capture of the products contained in the cartons.
The monitoring and control module is integrated by a touch screen and an electrical cabinet, allowing maximum control of the process and of the inspection and sorting programmes.
The equipment can include a roller conveyor that is coupled to the conveyor belt already installed in the plant. The products are placed on plastic boxes, and are moved along the belt until they are analysed by the camera and then classified by the Deep Learning system according to their category or type of product.
For the implementation of the Deep Learning software, in charge of classifying the different types of products, INNDEO&INSPECTRA’s technical service, together with the client, uses the Deep Learning tool, by means of which the classification of the products will be created and trained.
