Gravity-fed cutlery sorting device

Non-powered automatic spoon and chopstick sorting device using gravity drop and separation slits

This technology is a non-powered cutlery sorting device that features a concave, downward-sloping plate with separation slits, allowing only the thinner chopsticks to fall through. A lower chopstick transport section and a vertically stacked collection unit gather spoons and chopsticks separately.

Large dining facilities like highway rest areas, cafeterias, and wedding halls typically rely on users to sort cutlery at return stations, but frequent errors or improper placement often necessitate additional labor for re-sorting. Existing automatic sorting devices are complex, expensive, and require significant installation space due to their motorized components.

This technology operates without electricity, using only the weight and thickness of the cutlery to sort them. Nozzles at the top of the sorting plate spray liquid to provide a pre-rinse during transport. The slit width is adjustable, and the unit is mounted on wheels for easy mobility. It is ideal for cafeterias and banquet halls, significantly reducing labor for sorting and pre-washing.

Key Features:

• A cutlery sorting section featuring a concave, downward-sloping plate with separation slits along the center for chopsticks to fall through via gravity
• A concave chopstick transport section positioned below the sorting section at a downward slope to move chopsticks that have fallen through the slits toward the other end
• A collection unit vertically stacked at the ends of the sorting and transport sections to gather spoons at the top and chopsticks at the bottom
• Anti-slip ridges formed on the sorting plate, which features symmetrical slopes on both sides of the slits, and multiple nozzles that spray liquid toward the slopes
