Fully Automatic Optical Tray Distribution System

Optical Tray Distribution

In this case the trays start their journey through the factory from a mezzanine floor where operatives load the trays with two lens blanks and full instructions as to the prescription to be produced in the form of a barcode printed on a card.  They then place stacks of six trays on a storage conveyor.  The trays are de-stacked and then conveyed to the ground floor of the factory.  They are then fed automatically to all of the process machines. The conveyor system is controlled by a PLC (programmable logic controller) which communicates with all the machines individual PLCs. Sending and receiving signals concerning the loading and unloading of trays.
