Enmin FQIN digital frequency controllers for feeder optimisation

Enmin’s digital frequency controllers assist users to find the correct resonance frequency to ‘tune’ electromagnetic vibratory feeders.

Electromagnetic vibratory feeders all suffer from the inherent problem of repetition of build since they all are a combination of a machined base and a fabricated tray or bowl. The latter being the problem since no two will ever be exactly the same. The result of this condition lies in tuning the electromagnetic feeder to achieve the best possible conveying rate. Traditionally, springs would be altered or weights added to the system to compensate.

Enmin’s digital frequency controllers simplify the optimisation of the feeders.

The FQIN model can be used to service vibratory feeders from 4 to 15 A power. Operating from a standard single-phase power supply, the simple push-button operation quickly searches for the resonance frequency; and combined with amplitude adjustment, the vibratory feeder is able to be tuned to its maximum potential.

The problem of tuning any electromagnetic vibratory feeder is more apparent when the tray or bowl fabrication is of a more complicated design. For standard tray or bowl designs, the R series feeder controllers are acceptable. When multiple drives are employed either side by side or inline, the tuning function becomes much more difficult, so the FQIN overcomes this problem.

Many other features are available as standard with the Enmin FQIN, such as password protection which denies access to unauthorised personnel, connections for operational feedback load sensors and delay start and stop functions. The digital readout display program provides a host of messages for the ease of operation, fault finding and operating conditions. The FQIN is built to IP55 standard and complies with European CE standards for electromagnetic compatibility.
