Automatic tray filler

The utility model provides an automatic tray filler which comprises a rack and a longitudinal sliding rail arranged on the rack. The automatic tray filler is characterized in that movable frames with transverse sliding rails are arranged on the longitudinal sliding rail, and clamping and holding, turning and moving mechanisms are arranged on the transverse sliding rails of the movable frames. Two clamping and holding and turning mechanisms can be driven by two movable cantilevers conveniently to move along the transverse sliding rails on the movable frames to clamp and hold or loosen goods, meanwhile, the goods move along the transverse sliding rails, the lateral displacement of the clamped and held goods is achieved, the clamped and held goods are turned over through clamping and holding and turning mechanisms, the longitudinal displacement of the clamped and held goods is achieved through the movement of the movable frames along the longitudinal sliding rail so that tray filling of the goods can be facilita
