Combined vertical tray loading system and tray loading method

The invention discloses a combined vertical tray loading system and a tray loading method. The combined vertical tray loading system comprises a tray conveyor, a distribution conveyor, a tray loadingdistributor, a sensor and a controller, the tray loading distributor is connected and installed below an output end of a cloth conveyor, the tray conveyor is installed below the tray loading distributor, and the conveying direction of the tray conveyor is consistent with or perpendicular to the conveying direction of the cloth conveyor. The system and method solve the technical problem that an original tray loader developed based on a flat tray and a tray loading method cannot achieve uniform loading of all parallel independent fermentation cylinders in a combined vertical tray in a matched mode. The development of the combined vertical tray automatic fermentation system which is energy-saving, environment-friendly, efficient and lower in manufacturing and using cost becomes possible, andthe development and promot
