Technology supplied by Bosch Rexroth has enabled consumer-goods company Unilever to eliminate gripper problems that were occurring during pick-and-place operations on its Twister ice-lolly production line at its plant in Gloucestershire.

The grippers previously used on the Twister line were creating problems within three weeks of installation, with clear signs of wear. The grippers were failing to properly hold onto the ice creams and were letting them fall onto the production floor.

Bosch Rexroth was called in to work with Unilever to carry out an accurate sizing calculation to ensure that any new gripper was suitable for the job. Once calculations were completed, the decision was taken to trial two Bosch Rexroth GSP-A-25 grippers that only opened to the required 45º.

After several weeks in the field, an examination of the new grippers showed that there were no signs of wear at all. The decision was then taken to acquire eight sets of six grippers mounted on an angled mounting plate similar to the one that was currently in use, along with manifolds for the pipe work.

Key benefits of product application

  • The new grippers, fingers and plate supplied by Bosch Rexroth have solved Unilever’s gripper problem and are said to ensure that, with any future maintenance, a complete head could be replaced that would offer very fast changeovers and minimal downtime.
  • Unilever engineering technician Chris Burch said he was impressed that Bosch Rexroth continued to work with the company to find the most suitable solution.
  • The total outlay for the Twister solution was approximately £14,000; according to Burch, the cost of the solution was swallowed by the replacement and downtime costs associated with the previous grippers.
  • Burch said he believes the new technology is efficient and can be maintained much more easily and cost effectively than the previous gripper.
