Abstract

A feeder system (1) for supplying electrical components (20) to a pick-and-place machine (14). The feeder system has a two storage hoppers (2a,2b) respective storage outlets (6a,6b), There is a pick up location (3) and a passage (4) provides communication between the storage outlets (6a,6b) and the pick up location (3). A first fluid jet outlet 31 associated with storage outlets (6a,6b) provides fluid blasts to agitate components (20) the hoppers (2a,2b). A second fluid jet outlet (32) associated provides fluid blasts to propel the components (20) towards the pick up location (3).

Claims

1. A feeder system for supplying electrical components to a pick-and-place machine, the feeder system comprising:

at least one component storage means with two or more storage outlets;

a pick up location;

a passage providing communication between said storage outlets and said pick up location;

a first fluid jet outlet associated with one or more of said storage outlets for providing fluid blasts to agitate components in said component storage means; and

a second fluid jet outlet associated with said passage and proximate to said first fluid jet outlet for providing fluid blasts to propel said components located in said passage to said pick up location.

2. A feeder system as claimed in claim 1, wherein said first fluid jet outlet is located to provide air blasts through at least a first and second one of said storage outlets.

3. A feeder system as claimed in claim 1, wherein said first fluid jet outlet is located in a wall of said passage.

4. A feeder system as claimed in claim 1, wherein there are pressurised air supply means operatively coupled to said first and second fluid jet outlets by respective valves.

5. A feeder system as claimed in claim 1, wherein there is a third fluid jet outlet,

and wherein said first fluid jet outlet is located to provide air blasts through at least a first one of said storage outlets, and said third fluid jet outlet is located to provide air blasts through at a second one of said storage outlets.

6. A feeder system as claimed in claim 1, wherein said passage comprises an upwardly inclined portion which is upwardly inclined towards said pick up location.

7. A feeder system as claimed in claim 1, wherein an end of said upwardly inclined portion is directly coupled to said pick up location.

8. A feeder system as claimed in claim 1, wherein there is an intermediate portion of said passage between said pick up location and said upwardly inclined portion.

9. A feeder system as claimed in claim 1, wherein said storage means comprises at least two hoppers, each hopper being associated with one of said storage outlets.

10. A feeder system as claimed in claim 9, wherein each of said hoppers may comprise a first funnel portion for guiding components into a second funnel portion,

wherein said second funnel portion is adapted to receive said components such that a surface thereof is aligned to an alignment plane,

and wherein said second funnel portion is adapted to funnel said components into said hopper outlet.

11. A method for supplying electrical components to a pick-and-place machine by a feeder system having a component storage means with two or more storage outlets coupled by a passage to a pick up location, and having first and second fluid jet outlets, said second fluid jet outlet proximate to said first fluid jet outlet, the method comprising the steps of:

providing air blasts to said first fluid jet outlet associated with said storage outlets to agitate said electrical components stored in said component storage means, the agitation thereof allowing for the possibility of one or more components to pass through said storage outlets and into said passage; and

supplying air blasts to said second fluid jet outlet associated with said passage thereby propelling said components located in said passage to said pick up location.
