Vibratory Feeder Bowl Tracks
Track Cross-Sections
Hi-Negative Tracks
Hi-Negative Tracks have a 60° negative angle in the last quadrant of the vibratory feeder bowl. Some follow a transition from a positive angle to the negative angle. Typical parts oriented in these bowls are flat, irregular parts or parts with a projection on one side.
Positive Tracks
Positive Tracks have a less than 90° included angle between the track and the side wall of the vibratory bowl. Track angle is expressed in degrees of slope above the horizontal plane - usually 7°, 8°, 15°, or 60°.
Multiple Track
Multiple Track bowls have two or more tracks. Each track carries parts from the bottom of the vibratory bowl to its discharge. The discharge of stock bowls can have up to ten tracks. Advantages include higher production rates and the simultaneous delivery of fixed numbers of parts to the bowl's discharge.
Radius-Form Tracks
Radius-Form Tracks generally have a groove for the entire length of the track, but some just for the last quadrant. They are designed to feed a cylindrical part whose length is equal to or greater than its diameter. The track's radius should match the profile of the part being fed.
V-Form Tracks
V-Form Tracks contain grooves of 60°, 90°, 120°, or 150° as the included angle. Some run the entire track length, others only the latter part of the track. These tracks are designed to feed cylindrical parts.
Negative Tracks
Negative Tracks have a greater than 90° included angle between the track and the side wall of the bowl, expressed as degrees of slope below the horizontal plane - usually 15°, 30°, or 60°. Typical parts to orient include thin rectangular stampings and shallow pan or cap type parts.
