Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention separates light and flexible items such as vinyl bags and paper bags from waste that contains relatively heavy materials such as glass bottles and empty cans. This relates to a device for

[Conventional technology]

The equipment that separates and sorts substances with different specific gravities as described above is
Conventionally, wind sorting devices that utilize wind power have been common.

This type of wind sorting device has an air outlet and a suction hood that sucks air facing each other, and by passing the material to be sorted between them, it is separated into light substances that are sucked in with the air and thick substances that are not sucked. be.

In this case, the materials to be sorted are allowed to fall under their own weight, or are conveyed almost horizontally using a vibrating conveyor or the like.

[Problem to be solved by the invention]

In the conventional wind sorting device as described above, when the material to be sorted falls under its own weight, the 3f11 overspeed of the material is high, and the separation performance is poor because the clumps of the material to be sorted are not loosened. When a vibrating conveyor is used, there are drawbacks such as the outlet being clogged or heavy materials falling onto the outlet because the material to be sorted passes directly over the outlet.

Furthermore, since air that is not needed for sorting is sucked from the supply section and the discharge section of the substance to be sorted, it is necessary to increase the amount of suction air from the suction hood.

Another problem was that garbage packed in vinyl cannot be air-separated as it is, so the bag must be torn open to remove the contents.

[Means to solve the problem]

In order to solve the above problems, the present invention provides an apron conveyor in which a large number of projecting pieces are arranged and fixed at appropriate intervals on the outside of an endless belt arranged diagonally upward, and the upper side is used as a conveying side that runs diagonally upward. The lower claw of the drum, which is located on the apron conveyor and has a large number of claws on its outer periphery, moves in the opposite direction to the transport direction of the apron conveyor, and garbage-filled plastic bags, etc. are thrown into the apron conveyor. The present invention provides a separation device that does not utilize wind power, and includes a roll feeder that is driven to tear the materials by interaction with the projecting pieces of the apron conveyor.

[Effect]

Since this invention has the above-mentioned configuration, if garbage such as vinyl is directly thrown between the roll feeder and the apron conveyor, the bag will be torn by the protrusions of the conveyor moving in the opposite direction and the claws of the roll feeder. Bulky, lightweight items such as bags are caught on the protrusions of the conveyor, transported upwards, and discharged.

On the other hand, small items with relatively high specific gravity, such as bottles and cans, slip between the protrusions of the conveyor and the claws of the roll feeder, slide down the conveyor, and are discharged downward.
