Vibratory Bowl Feeder with Vision Inspection System
Jump to: Video ||System Specifications || Quote Request Form || Download Flier

We included a vision system to inspect each oriented part prior to discharge in order to ensure 100% accurate orientation. A proximity sensor detected a part in place, signaling the camera to take a picture of the part. If a backward part was detected, the PLC that controlled the vision system activated an air jet which blew the part off the track and back into the bowl feeder for recirculation.
View this short video that demonstrates the vision inspection of the parts as they pass through the vibratory feeder bowl. Mis-oriented parts are detected by the vision system which activates the PLC to blow them back into the feeder bowl for recirculation. Correctly oriented parts exit the feeder bowl onto a belt conveyor system and into the next step of the fully automated assembly process.
System specifications
- Feed rate: 30 parts per minute.
- Input voltage: 120V, 60 Hz.
- Vibratory bowl:
- 18″ basic diameter.
- Bead blasted stainless steel construction.
- Purge gate for part changeover.
- Belt conveyor:
- Auto-Kinetics Model 55 standard duty belt conveyor, 40mm wide x 35″ long.
- Reverse mounted 1/8 HP 130V DC motor.
- Table mount stands with locating pins so conveyor could be removed and replaced accurately. This allowed the customer to remove the conveyor to change the grinding wheel in their machine.
- Bulk supply hopper:
- 2 cu. ft. capacity.
- Stainless steel bin and tray.
- Vision system: Keyence camera with proximity sensor and PLC.
- Controls:
- Performance Feeders PF-2R for bowl feeder and hopper.
- Dart #15DVE forconveyor.
- Mounting surface: 1.25″ thick steel plate with 5 legs and leveling screws.
- Sensors and valves provided:
- Photoelectric sensor on conveyor monitoring part level in conveyor. When conveyor is full, the bowl is turned off to prevent parts from backing up into the bowl.
- Proximity sensor on hopper monitoring parts level in bowl, turning on hopper when parts are needed.
- Proximity sensor on bowl feeder in camera area, sensing part in place for vision inspection.
- Solenoid valve package with regulator and flow controls for air jets.
