Method and apparatus for sorting wastes

摘要

A method for sorting wastes wherein waste or recyclable material is supplied in carrier bags. A sorting apparatus includes a conveyor provided for receiving the carrier bags for separation from each other by guiding the carrier bags into containers according to an allotment. An RFID identifier is connected to each carrier bag. A closing member is provided with the RFID identifier in closing, or as verification of closing. At least one sensor is utilized on the basis of the information read from the RFID identifier of the closing member. At least one handling device, such as a robot, is provided wherein the at least one handling device is controlled to transfer the carrier bags to be sorted from the conveyor into the different allotments on the basis of the information given by the RFID identifiers. The invention also relates to an apparatus.

1. A method of using a waste sorting system for sorting individual carrier bags, each of which contains only one of multiple waste materials or only one of multiple recyclable materials,
the waste sorting system comprising: closing means used for closing or verification of closing of each of the individual carrier bags, a waste type of the one of multiple waste materials or the one of multiple recyclable materials being visually marked on the closing means of each of the individual carrier bags, an RFID identifier arranged in the closing means of each of the individual carrier bags for identifying the one waste material or the one recyclable material in each of the individual carrier bags, a conveyor capable of conveying each of the individual carrier bags, multiple handling devices (R1, R2, R3, R4, R5) arranged one after another along a length of the conveyor, each of the handling devices including: multiple sensor devices (S1, S2, S3, S4, S5) capable of reading the RFID identifier of each of the individual carrier bags, and multiple containers arranged adjacently to each of the handling devices (R1, R2, R3, R4, R5), the method comprising the following steps:
supplying only one of the multiple waste materials or the one recyclable material in each of the individual carrier bags;arranging each of the individual carrier bags one after the other on the conveyor while the conveyor is moving;moving each of the individual carrier bags via the conveyor until the one of the sensor devices (S1, S2, S3, S4, S5) is able to read at least part of the RFID identifier on one of the individual carrier bags arranged alongside a route of the conveyor, and then;depositing the one waste material or the one recyclable material from each of the individual carrier bags into an appropriate one of the multiple containers based on the RFID identifier read by the sensor device associated with the appropriate one of the multiple containers, andholding the waste material or the one recyclable material from each of the carrier bags in the containers for further processing.
