【発明の名称】グリッパーコンベヤ
Document Type and Number:
Japanese Patent JP3362907
Kind Code:
B2
Abstract:
A gripper conveyor includes a moving conveyor chain (1) which is provided with grippers (3). Each of the grippers (3) includes a fixed clamping jaw (31), a pivotal clamping jaw (33) and a spring (36) which biases the grippers (3) towards their closed positions. The conveyor includes an opening means (40) which functions to open selected grippers (3) while the conveyor chain moves, and the pivotal clamping jaw (33) of respective grippers (3) has a manouvering arm (37) which is activated by the opening means (40). The movable clamping jaw (33) is pivotally mounted on a shaft (32) for limited, free pivotal movement in the pivoting direction. Because the centre of gravity (331) of the movable clamping jaw (33) is distanced from the shaft (32) the movable jaw (33) is able to swing downwardly and outwardly into abutment with the support surface (N1, N11) on which the article, for instance a newspaper, to be gripped lies. Optionally, the outward swinging movement of the movable jaw (33) is assisted by a spring (35).
