At Wakefield plant Acmi supplied five end of lines, two for PET bottles and three for can lines. The last line commissioned by Acmi was line n°7 which had a very high filling speed equal to 120.000 cans per hr. The exceptional filling speed led to the splitting in two of the end of line to cater for a palletisation speed of over 160.000 cans per hr even with the 3x2 cans. The Acmi supply of equipment begins with a series of pack conveyors which are completely automated both with respect to switching from a single to double lane, and also in handling the different formats requested that range from 3x2, 4x2 and 4x3 for the pack containing 24 cans packed in trays.  Following on from that point, you will encounter the two second generation model Twisterbox layer formation systems constructed with carbon pliers, heart of the entire palletisation system. 

THE TWISTERBOX SUCCESS

The Twisterbox layer formation system is one of the most successful Acmi technologies and has literally revolutionised the concept of palletisation. In the plant at Wakefield there are a total of six Twisterboxes installed, thus proving that it is a very appreciated and extremely performing machine, which is also innovative, easy to use, maintenance free and with a completely automatic change over format. It is important to underline that the second generation of the most famous Acmi patent has been further improved both in terms of the programming as well as mechanical aspects. One of the most interesting Twisterbox’s component is the gripping head which is the keystone of the whole system. The two Twisterbox systems on line n°7 receive the packs from the pack conveyors, which are also equipped with an automatic format change over, and form the layers feeding two high speed high level infeed palletisers mod. Faster. The pallets coming out from the two Faster palletisers are transferred by a series of roller conveyors to two pallet stretch wrappers with superior top cover and automatic spool change over. The two stretch wrappers are positioned one after the other in succession. The end of line composed in this manner has:

• an elevated production speed,
• contained energy consumption,
• low maintenance and running costs.

One single operator is capable of running the entire system by means of a single operators panel.
