Operate to push out the objects to be sorted, and the objects to be sorted are sorted by a predetermined weight. The

選別コンベヤ型の重量選別機として、特開２００１−１９８５３１号公報がある。この従来技術は、選別コンベヤを被選別物の重量により沈下させて選別するために、選別コンベヤを弛ませて巻き掛け必要があり、選別コンベヤを搬送下手側の押し方向から駆動しなければならない。このため、選別コンベヤが長くなり、駆動構成が複雑化しコスト高となる不具合があった。 There exists Unexamined-Japanese-Patent No. 2001-198531 as a sorting conveyor type weight sorter. In this prior art, in order to drop the sorting conveyor by the weight of the object to be sorted, the sorting conveyor needs to be loosened and wound, and the sorting conveyor must be driven from the pushing direction on the lower conveyance side. For this reason, there is a problem that the sorting conveyor becomes long, the drive configuration becomes complicated, and the cost increases.

しかし、この実施形態では、選別コンベヤ５４を所定幅の幅広に構成し、選別コンベヤ５４の一側を沈ませることにより重量測定するので、構成を簡単化しコストの低減を図ることができる。 However, in this embodiment, since the sorting conveyor 54 is configured to be wide by a predetermined width and the weight is measured by sinking one side of the sorting conveyor 54, the configuration can be simplified and the cost can be reduced.

なお、前記計量器５９を図１１に示すように構成してもよい。フレーム部に選別コンベヤ５４の搬送方向に直交する軸に計量アーム５９ａを軸支し、且つ、計量アーム５９ａを選別開口部５８の搬送上手側に配設する。そして、この計量アーム５９ａの一端に計量板５９ｂを取り付け、バネ力調節自在のバネ５９を計量アーム５９ａの他端に連結している。そして、計量板５９ｂの搬送下手側に対向する誘導板５６には、搬送上手側に向かって下り傾斜の傾斜面部５６ａを形成している。 The measuring instrument 59 may be configured as shown in FIG. A weighing arm 59a is pivotally supported on an axis orthogonal to the conveying direction of the sorting conveyor 54 in the frame portion, and the weighing arm 59a is disposed on the upper conveyance side of the sorting opening 58. A measuring plate 59b is attached to one end of the measuring arm 59a, and a spring 59 with adjustable spring force is connected to the other end of the measuring arm 59a. The guide plate 56 facing the lower conveyance side of the measuring plate 59b is formed with an inclined surface portion 56a inclined downward toward the upper conveyance side.

前記構成によると、被選別物の選別排出に際し、計量板５９ａの搬送下手側を下方に円滑に回動させて、被選別物を円滑に排出することができる。また、計量板５９ｂの搬送下手側に対向する誘導板５６を搬送上手側に向かって下り傾斜の傾斜面部５６ａを形成することにより、選別コンベヤ５４の下方への沈み込みが円滑化し、被選別物を円滑に排出することができる。 According to the said structure, in the case of the sorting discharge of a to-be-sorted object, the conveyance lower side of the measurement board 59a can be smoothly rotated below, and to-be-sorted object can be discharged | emitted smoothly. Further, the guide plate 56 facing the lower conveyance side of the weighing plate 59b is formed with the inclined surface portion 56a inclined downward toward the upper conveyance side, so that the sinking of the sorting conveyor 54 is facilitated, and the object to be sorted is obtained. Can be discharged smoothly.
