【発明の名称】グリッパーコンベヤ
Document Type and Number:
Japanese Patent JP3362908
Kind Code:
B2
Abstract:
A gripper conveyor comprises a moving conveyor chain (1) which is provided with grippers (3), each of which includes a fixed clamping jaw (31), a pivotal clamping jaw (33) and a spring means (36) which biases respective grippers towards their closed positions and an opening mechanism (6; 41, 42, 68) which functions to open selected grippers (3) while the conveyor chain (1) is moving. The pivotal clamping jaw (33) of the gripper (3) is connected to a manoeuvering arm (37) which is activated by the opening mechanism. The manoeuvering arm (37) is mounted for limited pivotal movement in relation to the movable clamping jaw (33). An end-position means (45; 371) is provided for defining a pivotal end-position of the manoeuvering arm in a direction away from the movable clamping jaw. A biasing means (35) which is weaker than the spring means (36) functions to bias the manoeuvering arm (37) in a direction towards its end position.
