  • Patent number: 9725253
    Abstract: A material handling system for the disposal of materials in multi-floor buildings. The material handling system has one or more main chutes each having one or more sets of loading stations, queue chutes, and gates. The queue chutes store material to be disposed, which is held back from entering into the main chute by the gate. The material is loaded into the queue chute via an opening in the loading station. The opening of the gates is controlled using a material handling system controller, which is controlled via a control panel or automatically using a timer or based upon the output of one or more level sensors that can determine the fullness of the queue chutes. The main chutes can have primary gates to allow for safe maintenance of the system. The loading stations can have secondary access to the main chutes.
