A cap unscrambler is a device used to organize disordered bottle caps into a neatly arranged sequence, supporting the automation of capping processes. Its design principle is primarily based on vibration and gravity, with common types including vibratory bowls and waterfall unscramblers. The vibratory bowl uses vibration and rotation to guide caps to the center and arrange them in order. The waterfall type relies on gravity to move caps from one horizontal plane to another, achieving a uniform distribution. During operation, the device organizes the disorganized caps through vibration or gravity, ensuring a smooth subsequent automated filling and capping process. Cap unscramblers are widely used in the food, beverage, pharmaceutical, and cosmetic industries, enhancing production line efficiency and cap handling precision, and are suitable for various sizes and types of caps.
