The Computer integrated material handling is an autonomous equipment, composed of an automatic shuttle with shelving for vertical storage of products. This equipment allows you to store a work in progress and so, to ensure a buffer function during the manufacturing process. It applies to opening sashes (glassed or not) or to windows frames. It can also be implanted at the end of the process, for assembled windows, still as a buffer, in order to gather products per order, for instance, before palettizing. The sizing of the shuttle and the shelving is realized according to products (type and geometry); the technology used is the same whether it is opening sashes or assembled windows.
