A customer working with metal bolts without heads was using a conventional linear conveyor system to feed the bolts along the process. With this system, the bolts would frequently become wedged between moving parts, creating a logjam as bolts accumulated behind the wedged pieces. This caused substantial downtime because it required workers to stop the conveyor while they manually broke up the accumulation then loosened the wedged pieces.
The customer purchased a bowl feeder mounted with a MARTIN® NTS™ Pneumatic Linear Vibrator, in which the bowl is supported and balanced by leaf springs. Because the frequency and amplitude of the NTS are adjustable, the customer was easily able to fine tune the settings so that the metal bolts are moved gently through the process.
