Abstract

A gripper, an automatic analyzer, and a gripping method in which the gripper includes a connection rod that extends in a first direction; a first arm that is pivotally supported at one end of the connection rod and that extends in a second direction; a second arm that is pivotally supported at the other end of the connection rod and that extends in a third direction; a first gripping arm that is rotatably formed about a first rocking bearing and that extends in a fourth direction; and a second gripping arm that is rotatably formed about a second rocking bearing and that extends in a fifth direction. A straight line connects the first rocking bearing to the second rocking bearing becomes parallel with the first direction, the second direction becomes parallel with the third direction, and the fourth direction and the fifth direction are in point symmetry to a vessel.

Dependent claims

A gripper comprising:

a rod-shaped member that extends in a first direction in a horizontal plane;
a first arm that is pivotally supported at one end of the rod-shaped member, the first arm extending in a second direction different from the first direction in a horizontal plane;
a second arm that is pivotally supported at another end of the rod-shaped member on an opposite side where the first arm is pivotally supported, the second arm extending in a third direction different from the first direction in a horizontal plane;
a first gripping part rotatably formed about a first site that is one end of the first arm where the first arm is not connected to the rod-shaped member, the first gripping part extending in a fourth direction different from the second direction in a horizontal plane;
and
a second gripping part rotatably formed about a second site that is one end of the second arm where the second arm is not connected to the rod-shaped member, the second gripping part extending in a fifth direction different from the third direction in a horizontal plane,
wherein when a target is sandwiched by the first gripping part and the second gripping part and the target is gripped, or the gripped target is released, the gripper operates such that a straight line connecting the first site to the second site becomes in parallel with the first direction, the second direction becomes in parallel with the third direction, and the fourth direction and the fifth direction are in point symmetry to the target.
