First in first out
According to this principle, packages leave the accumulator in the same order they entered it i.e. the order in which they were produced. This makes it easy to remove only the affected packages from the line in the event of a production issue.
Packages queue up on a space-saving vertical spiral, available in different lengths to match the line's capacity. The filling machine determines the accumulator's speed at the infeed; the distribution equipment at the outfeed.
This device activates the accumulation function, feeding packages onto the spiral chain and releasing them again after the stop. It keeps the correct distance between packages, preventing crushes and consequently minimising package defects.
Several factors contribute to the easy operation of this machine: the Tetra Pak Operator Panel with its intuitive touch screen interface; easy access to essential working parts; large windows through which operators can observe accumulation at first hand.
