Abstract

This article describes an arrangement which provides the capability of dual grippers with a pitch motion on a robot to handle parts of different shapes or sizes. Robots often require a change of gripper configuration in order to handle a different size or different shape of parts. Accordingly, tool changes have been designed to handle these contingencies. However, a tool change may be impractical where the required change of gripper configurations is small, for example, a robot used for handling only two different size parts. Therefore, a much needed dual gripper has been provided which eliminates the necessity of a tool changer for handling parts of different sizes or shapes. The dual gripper consists of a dual yoke 3 which is attached to the shaft 8 of the rotary actuator 4.

Multi-Gripper Robot

This article describes an arrangement which provides the capability of dual grippers with a pitch motion on a robot to handle parts of different shapes or sizes. Robots often require a change of gripper configuration in order to handle a different size or different shape of parts. Accordingly, tool changes have been designed to handle these contingencies. However, a tool change may be impractical where the required change of gripper configurations is small, for example, a robot used for handling only two different size parts. Therefore, a much needed dual gripper has been provided which eliminates the necessity of a tool changer for handling parts of different sizes or shapes. The dual gripper consists of a dual yoke 3 which is attached to the shaft 8 of the rotary actuator 4.

Attached to one surface 9 of the yoke 3 is a special size gripper 1.

Attached to another surface 10 of the yoke 3 is another special size or shape gripper 2. Both grippers 1 and 2 can be activated by a common air line (not shown) or, if so desired, by individual air lines which give the capability of separate operation. The rotary actuator 4 is likewise pneumatically operated. However, hydraulic operation can be used.
