Parts supply system

A parts supply system comprising:

• first storing means for storing a plurality of trays loaded with respective parts, each tray being provided with a tray mark corresponding to the respective part loaded in the tray;
• a plurality of tray carrier means each having a respective carrier code, each tray carrier means for conveying only a respective one of said plurality of trays from said storing means;
• second storing means for storing a correspondence between each tray carrier code of a respective tray carrier means and a tray mark of a tray conveyed by said respective tray carrier means;
• and
• circulation means for circulating the plurality of tray carrier means to be loaded with respective of said plurality of trays along a circulation path which includes at least a tray loading position for receiving said trays, a parts supply position for allowing a robot to pick up the parts stored in said trays, and a tray discharge position for discharging said trays.

A parts supply system comprising:

• a storing section configured to store a plurality of trays loaded with respective parts, each tray being provided with a tray mark corresponding to the respective part loaded in the tray;
• a plurality of tray carriers each having a respective carrier code, each tray carrier configured to convey one of said plurality of trays from said storing section;
• a table configured to store a correspondence between each tray carrier code of a respective tray carrier and a tray mark of a tray conveyed by said respective tray carrier;
• and
• a circulation mechanism configured to circulate the plurality of tray carriers to be loaded with respective of said plurality of trays along a circulation path which includes at least a tray loading position for receiving said trays, a parts supply position for allowing a robot to pick up the parts stored in said trays, and a tray discharge position for discharging said trays, and wherein when a tray in a respective tray carrier is emptied at said parts supply position and is discharged at said tray discharge position, the respective tray carrier is reloaded with a new tray with the same parts as the discharged tray at said tray loading position.
