2. Description of the Related Art Conventionally, discarded glass bottles and cans are separated and transported by type for recycling.
Each type is stored in the stock yard. For example, bottles are colored and colorless and recycling costs and sales prices are different, so they are sorted by color and stored in a stock yard, and cans are recycled differently from steel cans and aluminum cans. It is stored separately for each material. In particular, when sorting bottles, in order to facilitate color identification, store them in a container so as not to be damaged and transport them to a sorting plant, invert the containers with a container reversing machine, receive the bottles, and place them on a conveyor. Transfer and remove bottles and foreign substances that cannot be recycled during transportation. After that, the bottles were identified one by one by a color sorter,
They are conveyed by a sorting conveyor and stored in a stock yard classified by color such as colorless, brown and green, and a residue yard classified by other colors that cannot be used.
The cans are separated into steel cans and aluminum cans by a magnetic separator and stored in stock yards classified according to material. When a predetermined amount of separated waste is accumulated in each stock yard, the waste is transported to a recycling plant by type.

[0003]

However, in the above-mentioned conventional method, for example, for bottles, a CCD camera or an ITV
(Industrial television), colorless,
Although the colors are classified into brown, green, and other colors, the bottles are identified one by one, so the identification process takes a lot of time, and the efficiency is poor and the cost is increased. Also, if the bottles are dirty, labeled, or damaged during transportation, it is difficult to identify the colors, and all items that are difficult to identify are separated into other colors. Since the waste is sent to the residue yard as unusable waste, the amount of waste is large, the amount of recycled waste is reduced, and the recycling efficiency is reduced. The present invention has been made in view of such circumstances, and even if the waste separately collected by color or material is dirty or damaged, the recycling efficiency is high, and inexpensive waste that can be processed in large quantities can be produced. It is intended to provide a transport / storage device.
