This low cost conveyor system features a dc motor driven system with vertical gauging unit, inductive and optical proximity detectors. The unit is fully self contained comprising a power supply, interface unit and a range of sensors and solenoid actuators.

The conveyor system carries out a simple parts selection process. The first selection is made on the basis of component height, tolerances can be set on the gauging unit allowing rejection of under and oversized components. Rejected components are ejected from the conveyor using a solenoid operated actuator.

Correctly sized components are sorted into plastic or steel. This detection process being carried out by a combination of optical and inductive detectors.

The interface circuits allow the conveyor system to be operated from any standard industrial PLC system using 24V dc logic levels. There is space within the interface board to drive the optional width detector 34-110 or an additional user defined detector.

The Single Conveyor can be upgraded to a Dual Conveyor by ordering Upgrade Pack 34-105.

The system requires a PLC capable of driving the following inputs and outputs:

    Inputs to PLC
  • Optical Proximity - 2
  • Vertical Gauge - 3
  • Material Detector - 1
  • Start Button - 1
  • Stop Button - 1
    Outputs from PLC
  • Conveyor Motor - 1
  • Gauge Motor - 1
  • Dispenser Solenoid - 1
  • Parts Selector/Ejector - 2

This application can be controlled from any of the PLC devices.
