PLC Controlled Automatic Object Detection and Diversion Unit

The project illustrates an efficient product industry model. The project we have completed is basically a factory automation model that certifies the products in terms height, weight or volume or all at a time with the arrangement of proper sensors. Since the finished products in a factory has to pass the quality tests in terms of height or weight, our project ensures to relieve the burden of manual inspection and further re-processing if required (i.e. if the product does not meet the required criteria, it has to be re-processed). The chief criterion we have focused upon this time is height. So the automation and quality assurance focuses the required height to be maintained for the finished products (with certain range or threshold).

The objects would be rolled over a belt drive (conveyer belt) and successive three height sensors would determine the required height. The three height sensors are the key components to decide whether the product passes the required height tests or not. The lowest height sensor signal that the object has a height below the standards and the uppermost sensor does the opposite; it shows that the height is more than that specified. The middle sensor determines the standard height and assures that the product has met the required height standards.

The other unit comprises of the diversion unit that dispatches the product to its proper place. If it has met the required height standards, the diversion would place the object to one container and if the product fails to meet the height standards, the diversion would then dispatch the object to another box suggesting the re-processing. The inclusion of proper cup-shaped unit provides the constant direction to the product when it drops off from the conveyer belt to the diversion height, which is separated by some height.
