Vibratory bowl feeders

We produce heavy vibratory bowl feeders for automatic loading of billets.

Application

The vibratory bowl feeder is used to continuously arrange parts from a randomly poured bulk into one row one-by-one so that they can be subsequently processed by an automatic production line. The vibratory bowl feeder together with the bin tipper tends to be a cheaper and faster alternative to robotic bin picking. In forges, vibratory feeders are used to automatically load billets into the induction heater.

Principle

The material is placed in a spring-loaded bowl which is vibrated by two vibromotors. As the bowl vibrates, the material moves along a spiral feeding track out of the bowl. Adjustable guide slats drop the misoriented billets from the track back to the bottom of the bowl. The eccentric mass of the vibration motors is adjustable and determines the magnitude of the oscillation. The speed of the oscillations is determined by the speed of the vibromotors. The unbalance and speed of the vibromotor are selected so that the vertical acceleration of the vibrations does not exceed the gravitational acceleration, otherwise the material jumps and noise increases.

Features

Thanks to patented elliptical oscillation technology our vibratory feeders outperform all competitors. The elliptical oscillation ensures reliable feeding with high conveyor speed under various conditions, low noise, low energy consumption, less wear and up to several times longer lifetime.

Our vibratory feeders can be used for a wide range of round and square billets. The automatic speed control maintains constant vibration acceleration, allowing maximum feeding speed with minimum noise with both full and empty bowl. As standard, we produce vibratory feeders in three sizes with a diameter of 1300, 1800 and 2400 mm, in left and right versions. The feed track is made of wear-resistant steel with a thickness of at least 10 mm. This ensures a long service life even in continuous operation.

Equipment

Optional equipment of the vibratory bowl feeder is atuomatic speed control, frequency converter, side chute for emptying and camera for monitoring the stock. If the feeder is equipped with automatic speed control, the control software calculates the current fill weight and alerts the operator if a refill is required.
