System for controlled distribution of components

A system for controlled distribution of components for timepieces, for an installation for automatic assembly of all or part of an article produced from at least one of said components, the system comprising:

• a vibrating bowl provided with an enclosure having a wall extending around a vertical axis of revolution of the bowl and wherein said components are placed in bulk, and
• an articulated gripping arm provided to distribute said components to said automatic assembly installation,
• the vibrating bowl comprising an ascending helical ramp extending along an internal face of said wall between a base and an upper edge of said vibrating bowl constituting an exit of said ramp, said components being able to travel along this ramp towards a supply platform including a first part having an upper face on which at least one component travels from said exit to a distribution zone to be seized by the articulated gripping arm, said supply platform including a second part positioned below said first part and including a linking portion connected to a lower face of said first part and guide portions positioned on two sides of said linking portion in a width direction and forming an obtuse angle with the linking portion, said supply platform being connected to said exit and extending above or in the enclosure of the vibrating bowl, said guide portions configured to direct improperly oriented components discharged from the upper face to the enclosure of the vibrating bowl.
