Abstract: At a conveyor forefront portion, velocity distribution of an airflow is provided. The velocity distribution is wind velocity distribution in a vertical direction of an airflow from a surface of an upper rectifying plate to a surface of a conveyor at the conveyor forefront portion, and has a maximum value in a range of less than 10 mm downward of the vertical direction from the rectifying plate surface. Moreover, a ratio obtained by dividing the maximum value by a wind velocity in the vicinity of the surface of the conveyor is 4 or more, and 12 or less. In a range other than the range of less than 10 mm, the airflow has a wind velocity equal to the wind velocity in the vicinity of the surface of the conveyor.

Abstract: A separation method includes: conveying a separation subject comprising a group of pieces placed on a conveyor in one direction; detecting, by a detecting device, compositions of pieces in the group of pieces placed on the conveyor; generating, by a blower, airflow at an end portion of the conveyor in a conveying direction in which the conveyor conveys the separation subject, the airflow having a velocity matching or substantially matching a conveying speed of the conveyor; stabilizing the airflow by a current plate placed along a trajectory of the group of pieces; and by a jetting device, obtaining position information of a piece of a particular material detected, and jetting pulse air toward the piece of the particular material when the piece of the particular material, which is travelling through air from the conveyor and whose travel is assisted by the airflow, passes by the jetting device.

Abstract: A separation apparatus includes a first air blower, a plurality of regulating plates, and a second air blower. The first air blower generates a first airflow toward a jumping direction of a separation target at a tip end of the conveyor. The first airflow has a wind speed that matches a transporting speed of a conveyor. The regulating plates are disposed along a flight path of the separation target. The second air blower generates a second airflow toward the flight path from below the flight path.

Abstract: A separation method for extracting a target 1 from a separation subject (101) in which the target (1) to be extracted and a non-target (2) are mixed. The method includes the steps of distinguishing the target (1) from the non-target (2); obtaining positional information of the target (1) distinguished; attaching a liquid to the target (1) based on the positional information; and extracting the target (1) from the separation subject (101) by bringing a catch member (140) into contact with the separation subject (101) such that viscosity of the liquid causes the target (1) to adhere to the catch member.

Abstract: A separation object including at least two types of resins with different glass transition temperatures (glass transition temperature of a first resin 1<glass transition temperature of a second resin 2) is placed on a separating member 3. Next, primary heating is applied at a temperature between the glass transition temperatures of the first resin 1 and the second resin 2, and pressurization is additionally performed to cause the first resin 1 to adhere to the separating member 3.
