Bowl feeder
Encyclopedia
Vibratory bowl feeders are the most common devices used to feed individual components ( aka : parts )in Industrial Assembly Automation Applications. Vibratory feeders are self-contained systems, comprising a specially tooled bowl feeder that orients the parts, a vibrating drive unit, upon which the bowl feeder is mounted, and a variable-amplitude control box. The bowl feeder, including an out feed accumulation track to convey parts along and discharge into the assembly machine comes in many shapes and sizes. The drive unit, available in both electromagnetic and pneumatic drives, vibrates the bowl feeder, forcing the parts to move up a circular, inclined track. The track is designed to sort and orient the parts in consistent, repeatable positions. The track length, width, and depth are carefully chosen to suit the application and component shape and size. Special track coatings are applied according to shape size and material of the component which aids traction, damage to the product and lower acoustic levels. A variable speed control box is used for controlling the vibration of the bowl feeder and stops the flow of parts to the out feed track via sensor
Sensor
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated...

Types of feeding systems

  • Bowl feeders: consists of a bowl top with a spiral track inside the bowl. The component parts are delivered from the bottom of the bowl feeder up the track into the top of the feeder as the bowl vibrates. The parts are the positioned in the proper position. These parts are usually then fed on to a vibratory or air track
  • Centrifugal feeders: also referred as ‘rotary feeders’, have a conical central driven rotor surrounded by a circular bowl wall. The feeder separate component parts utilizing rotary force and the parts revolve with high speed and are pulled to the outside of the bowl.

  • Step feeders: The component parts are collected from the hopper by elevating plates, pre-sorted and fed until they reach the desired transfer height. Key features of step feeder are that it operates quietly and without vibration.

  • Linear feeders: Horizontal conveying of components. Used to handle irregular supplies of parts from upstream equipment, creating a buffer store and smooth flow for further processes. Special application: Multi-track design, carpet feeder.

    : Bowl feeder coatings Minimise wear and tear, reduces noise and damage to parts.
  • Sound enclosure/cover: A foam-lined structure that absorbs the noise created by the vibratory feeder. Reduce noise and protects against dust and contamination.
  • Base plates: Enable easy mounting of the drive unit to the machine bed.
  • Sensors: Minimum/maximum level control on a linear track.
  • Hopper: Large, bulk container that stores material and regulates parts flow into the vibratory feeder system
