Automatic warehouse for the textile industry Safta Spa which duplicated the storage capacity.
Safta Spa was founded in 1925 with the production of textile fibers, in particular viscose-rayon, but in 1932 became one of the first Italian companies to introduce in the domestic market the cellulose processing. Thanks to particular techniques Safta was able to obtain a new film for the protection of the packaging, cellophane, becoming a worldwide leader in flexible packaging.The company is mainly recognized in the careful customization of various packaging, printed and plotted through special steel cylinders.
The problems of Safta’s warehouse arose right from the storage problems of these cylinders, extremely delicate and precious for the good result of the customizations.
Since 1994 the company has been equipped with an automatic storage system with a storage capacity of approximately 7040 locations; with the passing of time it was necessary to introduce some changes that could meet three specific goals: growth in activity, success of new markets and renew the warehouse now marked by the wear of time. The input and output stages represented a problem to the warehouse, because, being manually handled, often they caused damage to the printing cylinders.
The solution proposal by Automha has allowed Safta not to overturn the original warehouse structure, but to strengthen it through a review that has led to considerable optimization through significant saving. The storage business is organized in different areas depending on the merchandise type and the type of interaction with the production lines. The warehouse is thus divided into an area for raw materials and semi-finished products, a shipping warehouse and the warehouse for the storage of the printing cylinders. For the latter area, Automha has made a careful study of all types of cylinders, of handling flows and storage requirements, thereby enhancing the capacity of stocking and automate all operations in order to preserve the integrity of the goods . The shelving already in place has been refurbished and was built a new front, so doubling the storage capacity by combining two sheds which are first divided by a symmetrical rack. The plant built by Automha is thus constituted by 7 lines of two-faced double-deep shelves, plus 2 lines of shelves always single side, double depth. The total capacity of the warehouse has grown from 7400 to 14,700 locations. The warehouse is entirely served by double masts stacker cranes with telescopic forks moved by the transferring bridge. The input / output bay has been automated and the warehouse today receives 3 flows: the new cylinders awaiting engraving, worn cylinders waiting to be refurbished and the cylinders in movement towards the production department. Each cylinder is identified by a punching present on the central pivot and with a bar code label. During each mission the stacker crane port to the output bay two cylinders at one time, where are placed on special trolleys, after having verified the congruence of as extracted by reading the barcode applied. Today the operator must only manage the handling of the trolley already loaded.
The choice of this type of solution has allowed to duplicate the storage capacity, to minimize the number of active AS/RS and limit support infrastructure present in stock. Furthermore, the reuse of the existing structure has allowed the insertion of a flexible and compact machine, able to move at best between the stowage high density shelving.
