Fill Level Check by Ultrasonic Distance Sensors with IO-Link on Vibratory Bowl Feeders

To reliably replenish the supply of screws, rivets or bolts in vibratory bowl feeders, the fill level must be constantly monitored. The vibration of the container separates the objects down a spiral chute and transports them away which depletes the supply in the feeder. The fill level is monitored by an ultrasonic distance sensor with IO-Link. This sensor delivers two digital switch signals regardless of the material. The switching points are set via IO-Link. The operator is therefore informed of the fill level at two stages: if the container is well filled or if it is almost empty.
