A large number of small parts, connectors, consumables and other materials flow through the crates between the various production stations, the customer in the warehouse for the ingredients, the selection of robots to depalletize the crate stacks. 3D vision system for positioning the crates accurately gripped placed on the conveyor belt, at the same time, return to the warehouse of empty crates depalletized return to the position. Most of the crates are made of plastic, with different colours and sizes, and arranged in different stacking patterns such as side-by-side and back-to-back, which requires a certain level of gripping accuracy. By using the large field of view laser 3D vision system, to help customers realise the efficient flow of materials.
