Abstract: The invention provides an adjustable tray dispenser having a plurality of tray guides for individually dispensing trays from a tray stock. Each of the tray guides is driven by a flexible drive shaft coupled to a gear box. The flexible drive shafts enable the independent adjustment of each tray guide with respect to each other, the dispenser, and the tray stock. A motor coupled to the gear box provides variable speed rotational motion to the flexible drive shafts. Each of the tray guides has a dispensing head that includes a timing adjustment mechanism. The timing adjustment mechanism enables the synchronization of all of the dispensing heads prior to tray dispensing. The independent adjustment ability of the tray guides enables use of the system with any size or shape tray.
