Gripper assembly for enhanced robotic palletising
A motorised bag gripper assembly is the latest innovative solution to emerge from the Chronos Richardson comprehensive research and development programme
The contract, which is worth almost three quarters of million pounds, was awarded to Chronos Richardson by Mitsui Engineering and Shipbuilding Company Limited, the main engineering contractor for the project.
Nippon Goshei have pioneered the process for producing high quality, high density plastic resins and the UK site will supply customers across Europe.
One of the main uses for the resin is in the manufacture of high quality food films used in the rapidly expanding ready meals market.

Ironically, another major customer for the resin is the manufacturer of the bags themselves used for the product.
Mitsui and Nippon Goshei set strict technical and process parameters for this vital equipment in terms of speed, accuracy, reliability and hygiene.
The bagging line includes a belt-fed, high speed Richard Simon UBM weigher, automatic MK4 bag placer and heat sealer, check-weigher, low level palletiser and shrink wrap equipment.
The bagging line is capable of filling either 20 or 25 kg bags at speeds of up to 600 bags an hour.
Conservative engineering and design parameters ensure that critical components work well below their ultimate capability, thereby providing long term reliability.
When required, product can be diverted to the second line, which can automatically fill octabins by multi-dumping product from the weigher to achieve the larger 550 kg target weights.
The octabins are placed automatically onto pallets and presented one at a time to the filling spout.
When filled, evacuated and sealed, the box is conveyed away ready for a new one to take its place.
All critical contact parts are constructed from polished stainless steel to facilitate product line changes and ensure the strict hygiene requirements are met.
Given the high value of the product, minimising 'giveaway' whilst still maintaining accurate target weights is vital.
The design features of the UBM weigher and controller optimise target weights and automatically compensate for any minor changes as they occur.
For 25 kg bags, accuracies of +/- 10 g are readily achieved.
Before installing the equipment on site, Chronos were required to demonstrate its effective operation during in-house trials witnessed by senior engineers from both Mitsui and Nippon Goshei.
