Suitable goods types and scene matching for fluent shelves The core requirements for fluent shelves for goods are "neatness, a certain degree of hardness, and suitability for sliding", mainly suitable for three types of goods and scenarios. One is boxed/boxed small items, such as daily necessities and food for e-commerce, cosmetics and stationery for retail. These types of goods have a regular shape and moderate weight (5-30kg per box), suitable for sliding along smooth bars; Secondly, small and medium-sized components in the manufacturing industry, such as screws and bearings in automotive parts, chips and resistors in electronic factories, can be used in conjunction with component boxes to achieve efficient picking of "one person, multiple positions"; The third is fast turnover production materials, such as packaging materials for food processing plants and fabric rolls for clothing factories (requiring customized curved fluent strips), which ensure the freshness of raw materials through "first in, first out" and avoid stockpiling. It should be noted that it is not suitable for overweight, oversized, irregularly shaped or easily deformed goods (such as bagged flour, soft packaged snacks), which are prone to getting stuck in flowing strips or unable to slide due to deformation.
