The automatic warehouse Chronos 812 has been designed for handling any kind of fabric rolls. The maximum dimensions of the fabric rolls are:

• Diameter = 400mm
• Fabric height 1600mm
• Roll weight 35 kg

The machine is made by three stations:

• Preloading / unloading station: it takes care of managing the rolls entering the warehouse (positioned on the lower belt) through a FIFO type queue, up to a maximum of 9 pieces, which will be stored inside the warehouse itself; it also guarantees the unloading of the pieces leaving the warehouse. Both stations are made with PVC belts, directly controlled by the warehouse software.
• Management warehouse: it is the actual warehouse, where fabric rolls are allocated in cradles, handled using a chain guided revolver system. The handling phase both in and out of this station is managed by the warehouse software.
• Interfacing station with spreader / unroller: this station automatically picks up the pieces returned by the spreading (with a special roll rewinding cycle) and gives the next one to the spreading to continue the process.

The warehouse structure can be customized, according to the number of rolls to manage, both in height and in length. The modularity of the machine also allows to manage rolls of different diameters. The strength of the 812 Chronos machine consists in making the next roll immediately available before the unloading operation of the previous one is completed. In this way, the dead times of processing are reduced, increasing the productivity of the spreading line and the related cutting connected to it. Chronos can manually manage the work queue (taking charge of a sequence of fabric rolls to be processed) or it can acquire the work queue to be created using the planning & management software. Included within IMA lines, the 812 Chronos warehouse meets the requirements of industry 4.0. It is also interfaceable with other external systems (to be estimated case by case).
