Abstract

A sorting mechanism that only removes workpieces (10A). The sorting mechanism (1) allows the workpieces (10A) to pass among the workpieces (10A, 10B) conveyed along the conveyor path (20) and prevents the workpieces (10B) from passing. The stopper (33) of (32) displaces between a blocking position that blocks the movement of the conveyed workpiece and a non-blocking position that does not block the movement, and the front end portion (42a) of the arm portion (42) The release member (4) is disposed closer to the conveyor path (20) than the arm portion of the restricting member, and a rotational force application mechanism that causes the rotational force in the direction of disposing the stopper to the blocking position to act on the restricting member. The bolt (36) restricts the first arm portion of the member and brings the front end portion (362a) into contact with the arm portion of the releasing member. When the restricting member arranges the stopper in the blocking position, the bolt of the restricting member secures the arm of the releasing member. The part is arranged in a position that only contacts the workpiece (10A).

Description

technical field [0001] The invention relates to a sorting mechanism for workpieces. Background technique [0002] Patent Document 1 discloses a sorting mechanism in which an area inclined so that the inner peripheral area is lower than the outer peripheral area is provided on the conveyance path of the workpiece, and a predetermined line is provided at the boundary between the outer peripheral area and the inner peripheral area. The gate member having an opening of a small size allows only workpieces of a size that can pass through the opening among the workpieces conveyed to the outer peripheral area to pass through the opening of the gate member and move toward the inner peripheral area. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Publication No. 59-7081 [0006] The problem to be solved by the invention [0007] In the sorting mechanism disclosed in this patent document 1, as long as the workpieces can pass through the ...

AI Technical Summary

Problems solved by technology

[0008] Therefore, when the workpiece to be taken out through the gate member (target workpiece) and the non-target workpiece smaller in size than the target workpiece are mixed with the workpiece conveyed in the conveyance path, the target workpiece cannot be taken out by using the sorting mechanism of Patent Document 1.
