The filled cartons each weighed 15 kilograms, so durable boxes are required to sustain this weight, however manually forming, filling and sealing these boxes was a time consuming task. Twin walled boxes were required which can be difficult to form on an automatic case erecting system as there is a high risk of failure due to the heavy board that needs to be opened and folded.
Consequently, Endoline installed their fully automatic 221 case erector, which has an integrated dual opposing vacuum technology. Two vacuum systems are used that clamp to each side of the case during the forming processing, applying the same amount of pressure to simultaneously open it from both sides. This system allows for consistent, positive opening of the case.
The machine also includes pneumatic rockets which open the outer case flaps before the inner case flaps, which overcomes issues with folding the case flaps that more conventional case erectors regularly have.
Endoline equipment is available in Australia and New Zealand through Walls Machinery.
