Abstract

A vibratory feeder bowl is utilized to feed transistor chips to a work station. At the terminus of the feeder bowl the transistor chips are uniformly oriented and in a continuous line. Oriented transistor chips 1 hang by their collector balls 2 onto ledge 3. As chips 1 turn corner 4 of the overfeed control section they see an initial turn 4 in ledge 3. Turn 4 performs two functions. First, it provides a downward velocity to chips 11 so that the second steeper turn 5 does not seem so steep to the chips. Secondly, turn 4 tilts the chips forward as they travel along the incline. Chips 1 flow down around second turn 5 and then straight into end track 6. If chips 1 are not being picked up from the end track 6, they back up in a line as shown.

Vibratory Feeder Bowl With Overfeed Control

A vibratory feeder bowl is utilized to feed transistor chips to a work station. At the terminus of the feeder bowl the transistor chips are uniformly oriented and in a continuous line. Oriented transistor chips 1 hang by their collector balls 2 onto ledge 3. As chips 1 turn corner 4 of the overfeed control section they see an initial turn 4 in ledge 3. Turn 4 performs two functions.

First, it provides a downward velocity to chips 11 so that the second steeper turn 5 does not seem so steep to the chips. Secondly, turn 4 tilts the chips forward as they travel along the incline.

Chips 1 flow down around second turn 5 and then straight into end track 6. If chips 1 are not being picked up from the end track 6, they back up in a line as shown. When the total force, which builds up on chips 1 due to the length of the line of chips, becomes large enough chips 7, 8, or 9 or all three chips are forced out of line as shown by the arrows. The chip or chips forced out of line fall into hole 10 and are returned to the center of the vibratory feeder bowl.
