Automatic stacker cranes were first used in a cold store in the USA in 1962 and there are now many installations throughout the world. The store height can be increased considerably, to 16-20 m, or even higher if the rack frame is used to support the roof of the cold store. The operation of such a store can be by using a crane with the operator inside the store, driving the crane from a heated, insulated cab, or can be fully automatically operated by a computer. One crane can service some 4000 pallet positions at the rate of 50 pallets per hour. 

This is about 9 bags per minute, or one pallet of 40 bags every 4.5 minutes. An automatic bagging and palletizing unit will be specified to reduce operating costs. The drum and carton filling operations will be done manually (see Fig. 5E-1). 

A fork-lift truck will be used to take the pallets from the packaging area to the warehouse. Two trucks will be needed to keep pace with the automatic bagging equipment. If 2 each are used for storing cartons and drums, 1 for handling raw materials, and 5 for loading railroad cars and trucks, a total of 12 will be required. 

A variety of compound processing units are available which automatically treat, dry and often stack the compound into pallets for storage. These machines can be of the type which handle individual sheets of rubber compound, or can pass a continuous sheet, or strips through the system and then wig-wag it into the storage units. 

Filling Conveyor. Filling line transfer system is an automatic, nonsynchronus, variable-speed drive unit complete with filling pallets and nests for the five different munitions filled and closed on the line. This unique system moves work pallets from station to station and provides accurate shot pin alignment for the work piece as various operations are performed, and features automatic acceleration and deceleration of the filling pallets. Operation is unusually smooth, quiet and safe. 

After pressing, the munitions are released and travel to a manually-operated stop where an operator removes the filled and closed munitions and transfers them to the degreaser (cleaning) unit. The empty pallets are automatically released from this station and travel back to the front of the line to accept empty munitions for another cycle. 

Safe separation studies were conducted to achieve increased production and cost effectiveness with improved safety. A typical ammunition production line flow diagram (in this case for the manufacture of 105 mm projectile) consists of several work areas as shown in Fig 8. ( (l) Receiving and storage, (2) Box open and inspect (3) Melt Pour (U) Cool (5) Hold (6) Funnel Pull and (T) Riser Preparation.) Explosive material is transferred by automatic conveyor between these work areas. The requirement was to establish safe separation between explosive boxes, pallets with and without funnels, buckets, and to determine critical height of continuous feed flake Comp B and TNT. The objective of these tests was to establish minimum nonpropagation distances between these items so that an explosion chain reaction will be prevented. 

Palletizers can be furnished with automatic pallet dispensers, glue systems, automatic bottom-pad dispensers, and automatic tier-sheet dispensers. Palletizers offered are required to have a programmable logic controller (PLC) for multisize cases. It is possible to program different tier and pallet patterns into a PLC unit, and thus change over from one size to the other by means of selector switches. A palletizer can automatically arrange the cases for each tier, dispense the pallet, or insert the tier or tie sheets. These functions can alternatively be performed manually by an operator.
