Compensation stacking

PROBLEM

Stacks of magazines (as delivered to newsagents) and books are created in compensating stackers. Magazines/books are fed into the compensating stacker where they are collated into a stack (a pre set number). The stack is then transferred by conveyor to either a strapping machine or automatic palletizer. Due to the slippery nature of the covers, the magazines/books slip as the stack travels along the conveyor, resulting in incorrect stack heights, stacks falling over or poor stack presentation. 

SOLUTION

Static generating equipment is installed to ‘pin’ the magazines together, thus ensuring that it stays in perfect shape for the next operation. Each magazine entering the stacker is charged so the bond together as they are stacked. 

As the stack transfers to the strapping process a further charge is applied to the stack ensuring the transfer process to be completed without the stacked magazines from misaligning.  

This saves considerable manpower that is otherwise needed to re-stack the piles
