Abstract
Official abstract text for this publication.
A shearing mechanism is provided including a pair of blade units comprising shearing blades respectively; and a motion mechanism configured to move at least one of the pair of blade units along a predetermined trajectory in such a manner that a velocity thereof does not become zero while maintaining a relative posture of the pair of blade units, wherein the pair of blade units are configured to cut an object by overlapping the shearing blades of each other during the motion.
First claim
Opening claim text (preview).
What is claimed is: 1. A shearing mechanism, comprising: a pair of blade units comprising shearing blades respectively; and a motion mechanism configured to move at least one of the pair of blade units along a predetermined trajectory in such a manner that a velocity thereof does not become zero while maintaining a relative posture of the pair of blade units, wherein the pair of blade units are configured to cut an object by overlapping the shearing blades of each other during the motion. 2. The shearing mechanism according to claim 1 , wherein: the predetermined trajectory is a circular trajectory, and the motion is a circular motion. 3. The shearing mechanism according to claim 2 , wherein: the motion mechanism is configured to engage with the pair of blade units via an engagement portion, and one part of the engagement portion relatively performs the circular motion around other part of the engagement portion. 4. The shearing mechanism according to claim 2 , wherein: the circular motion is a constant velocity circular motion, and the pair of blade units are configured to cut the object by periodically overlapping the shearing blades of each other during the motion. 5. The shearing mechanism according to claim 3 , wherein: the motion mechanism has a plurality of eccentric cams, and the eccentric cam has two different rotational axes, one of the pair of blade units is engaged with one of the rotational axes, and other of the pair of blade units is engaged with other of the rotational axes. 6. The shearing mechanism according to claim 5 , wherein: the rotational axis is configured to directly accept a power of the motor. 7. The shearing mechanism according to claim 1 , wherein: the shearing blade with respect to at least one of the blade units comprises an extrusion surface at an end of the shearing blade, and the extrusion surface is configured to extrude a foreign object in contact with the extrusion surface during the motion. 8. The shearing mechanism according to claim 7 , wherein: the extrusion surface is configured to extrude the foreign object when the shearing blades are not overlapping.
