FlexiBowl® allows the orientation and separation of components, by the combined movements of a servomotor and an impulse generator.

The FlexiBowl® system is highly versatile and able to feed objects of any:

  • Geometry
  • Surface
  • Material

This is possible thanks to the vast choice of rotary discs, available in multiple colours, textures, resistances and degrees of surface adhesion.

The working principle is very simple and straightforward: the bulk feeder releases and lets the parts fall onto the FlexiBowl® surface and they are effectively separated by the combination of bidirectional rotation and the impulse generator. Once the parts are singulated, the camera recognizes them and sends the coordinates to the robot for the pick-up.

The set of instructions allows changing the speed parameters, the acceleration and the impulse frequency according to the parts’ geometry, to achieve an optimal result.

FlexiBowl Traditional


Traditional Operating Mode

The flex feeder routine includes 3 different activities:

• Dropping refers to the action of the bulk feeder
• Separating refers to the action of the flexible feeder
• Picking refers to the action of the robot

By splitting and confining every single phase of the process in a dedicated sector, dropping, separating and picking take place at the same time.

This process usually lasts 0.5 seconds, which is a benchmark in the flexible feeding market.




FlexiTrack enables the circular conveyor tracking of the FlexiBowl. In the FlexiTrack vision system operates in a separate sector located right before the robot picking area. The robot and vision processing are simultaneous so the time waste in processing data is reduced. In this system a second camera is positioned before the bulk feeder to balance the parts dropping.
Multiple parts


Multiple Parts Feeding

Multiple Parts Feeding allows simultaneous feeding of different components.

Up to 6 different types of components can be managed by the same FlexiBowl® reliably. A separate bulk feeder is needed for every single type of component.

Multiple parts feeding allows to minimize layout and production costs. The feature can be equipped to FlexiBowl 500, 650 and 800.
