Abstract
A shaping or cutting machine, especially a skinner, at which an operator hand-feeds material to be cut or shaped toward a blade. Hand proximity detection devices are provided for operator safety; machine-vision across a surveilled volume before the blade, and conduction sensing devices. The blade is mounted on a rapidly retractable frame. Power from release of a spring physically moves the blade to a safe position if a hand is sensed. A gripping roller is driven by a rapidly stoppable motor.
Claims14
1) A machine for shaping an item held by an operator's hand or hands;
- the machine having a chassis and having a blade supported at a Run Position on a blade mount, the item being advanced at a feed velocity and in a direction toward the blade, characterised in that the machine includes a proximity sensing device configured to detect the operator's hand when in unsafe proximity to the blade and if detected, of activating a retraction mechanism adapted to use power derived from energy held in an internal energy storage and release device to physically retract the blade from the Run Position in the direction at a velocity greater than the feed velocity and place the blade in a Safe Position.
