16) Modular drawer cabinet
Modular drawer cabinets make efficient use of storage space by providing secured enclosed storage for small or high value parts. The operator has a clear view of all stored items as the drawers are withdrawn from the cabinet.
An added value of modular drawers is that each drawer can be positioned or sub-divided into smaller storage cells. Modular drawer cabinets, used extensively in tool cribs, parts supply rooms and maintenance areas, provide higher density, improved organization, more security and protection and a greater utilization of storage space.
Such modular drawer cabinets may be wheeled or fixed in place.
Palletizers are special machines capable of building a complete unit load on a pallet. Although the most common application is for cases, some palletizers can also handle sacks and bags. A less common palletizer application would be for special products such as sheet stock.
There are two general methods employed for automatically building a full pallet. One makes use of a fixed position or overhead gantry robot with end effectors suited to the individual loads, such as vacuum lifts or a gripper. The other method employs more complex mechanisms for forming pallet layers off line, one at a time, and then shifting or transferring each successive layer onto the pallet as it is lowered via a lift/lower table.
18) Fixed Aisle Storage & Retrieval
Fixed Aisle (F/A) Storage & Retrieval Systems consist of one or more long, narrow aisles framed on both sides by a steel (and sometime extruded aluminum) storage rack structure into and from which loads are automatically stored and retrieved under computer control. The storage/retrieval function in each aisle can be performed a variety of ways. However, the most common was is by a machine that consists of a floor running, traveling structural frame or vertical mast that guides and supports a hoisting carriage on which loads are carried. One or more shuttles or insertion/extraction devices on the hosted carriage manipulates loads into and out of adjacent or opposing storage rack positions. All three machine motions; horizontal (down aisle), vertical and shuttle action are independently and automatically controlled.
