Title:
WIPER MECHANISM FOR OPTICAL SORTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/123990
Kind Code:
A1
Abstract:
Provided is a wiper mechanism for an optical sorting machine, whereby a wiper reciprocating drive mechanism is not fouled by dust or the like, and a transparent plate of an optical part can be cleaned. The wiper mechanism for the optical part in the optical sorting machine has a falling space in which a sorted object falls, and a sealed space in which an optical detection means for detecting the sorted object is disposed. The optical part of the optical sorting machine has a transparent plate for enabling detection of the sorted object by the optical detection means in a partition wall between the spaces. A wiper for coming in contact with the transparent plate and cleaning the transparent plate is disposed in the falling space of the optical part, and a reciprocating drive mechanism for causing the wiper to slide along the transparent plate is disposed in the sealed space. Movable parts of the wiper and the reciprocating drive mechanism are connected so as to be integrally movable by a magnetic force via the partition wall between the spaces.
