  • Method for removing a cap from a container with a cap engaging unit
    Patent number: 5430923
    Abstract: The automated container cap remover and method for cap removal includes a drive for causing relative rotation to occur between a container cap and a cap engaging unit. The drive brings the cap engaging unit into engagement with the cap and then slips to permit the cap to be unscrewed from the container. A control unit senses the torque created by the relative rotation between the cap and cap engaging unit, and when a drop in torque is sensed, the control unit causes the drive to move the cap and cap engaging unit out of engagement.
