Vibratory feed controller provides solutions for Easiweigh's multi-lane / stand-alone machines

Easiweigh of Worcester specializes in the design and manufacture of custom-engineered weighing systems. Around 90% of the company's business is for the food industry, the remainder going to the hardware market for handling small components. All of the company's machines employ vibrating feeder systems to transport product between feed delivery systems and weighing stations. On many of these machines, the feeders are controlled by vibration controllers from REO UK.

For the food industry, Easiweigh supplies machines for many different weighing and measuring applications including bagging, tray filling and boxing of raw produce through to portioning cooked meal ingredients (wet and dry material). Most of the company's machines are for multi-lane, continuous feed lines but it also offers units for low volume / small batch applications. The machines offer accuracies determined in grams up to hundreds of kilos.

REO's controllers - REOVIB - are employed by Easiweigh principally for PLC controlled multi-lane machines with more than eight lines and some stand-alone units. The REOVIB are frequency inverters that produce an output frequency independent of the mains frequency to drive vibrating feeders. They can be programmed to provide the correct vibration amplitude to achieve the required delivery rates. Frequency can be varied on the 'fly' so that feed rates might be adapted readily to match different / changing requirements.

"We have been using REO controllers for a number of years," said Chis Breeze, Technical Manager at Easiweigh. “The REOVIB gives us an effective solution for our larger machines, particularly where PLC's are involved. The company has also been very accommodating; helping with development and producing customized units to fit our control panels.

REOVIBs can be used for linear, bowl and hopper feeding arrangements permitting a wide scope for potential applications.

Easiweigh is a member of the GSH Group which specializes in product handling systems.
