Flexible Use and Reliable Protection of Goods to be Stored:

Cassette Flats

Cassette Flats – The Efficient Answer to New Challenges in Storage

For many applications in processing industry, coated material (aluminum, steel etc.) is essentially not delivered in form of coils, but stored in cut and processed state. An uninterrupted material flow for these plate stacks requires particular heavy-load rack systems ensuring protected storage and minimum pressure on items comprised, thus avoiding damage to surfaces and material structure. Another important condition is maximum flexibility with respect to an environment changing from day to day, and ensuring trouble-free handling under any circumstances.

Even though plate stacks may have to be piled up one above the other, insertion resp. removal should not be restricted, and an excessive load should not be applied, as some materials are very sensitive. For this reason, corresponding objects have to be stored at a sufficient distance with respect to each other, so they can be displaced without damages. ShuttleTower, an innovative storemaster®– invention for sheet warehouses with cassette flats, was developed with these particularities in mind, as conventional storage systems in corresponding situations are not able to maintain the speed of material flow nowadays required. This configuration proves its worth especially in sectors, in which sheet types frequently used, can be positioned only at limited numbers. In these situations, material by means of a stacker is taken out from sheet tower storage systems equipped with cassette flats, and transported to the machine – this the quickest way of handling.  This method enables any number of sheet types intended for subsequent processing to be contained in a warehouse.

Economically meaningful and efficient handling solutions are essential for all modern enterprises, particularly in phases of growing production. Besides optimum consumption of space, quick access, easy management and safe working environment are decisive criteria for purchase decisions in this branch of business. 70% of the throughput times within a factory can be assigned to internal transportation, so increased profitability cannot be achieved without evaluating this factor. Sheet storage equipment and systems configured by storemaster® offer individual solutions, and may –corresponding to the intention of the client-  cover the entire transport chain from goods receipt of raw material up to dispatching of the final products. The sheet storage design represents the core of an optimized material flow.

The advantage of cassette flats is their ability to store an extremely high number of material types on a narrow area, so this variability ensures a maximum of flexibility in daily use. As waiting phases of machines can considerably be reduced (sometimes they may even disappear completely), their utilization ratio correspondingly improves. As the necessity for complicated handling procedures is eliminated, safety at the working place is enhanced as well.

Device for Quick Exchange of Sheets + Disposal of Residual Grates + Collection of Parts

By means of this manual exchange portal for system pallets (flats of all kind) with a capacity of up to 3 t, the waiting phase for the sheet type of the following task, may be reduced to zero. This cost-efficient solution is advisable particularly in the case of long cutting cycles and large numbers of identical sheets per task. Further useful options include disposal of residual grates (refer to special flat for residual grates), removal of finished products or entire plates after cutting, resp. integration into other production sequences. Sheet supply or removal may be take place at either transfer point in all of the three directions.
