Method for controlling the movement of an operating assembly of an apparatus for the automatic processing of articles

A method for controlling a movement of an operating assembly of an apparatus for the automatic processing of articles, comprising:

• defining a movement trajectory of said operating assembly configured to perform a processing on an article of said articles,
• defining, for at least one segment of said movement trajectory, a deviation of said operating assembly from said movement trajectory, such that said operating assembly can be moved in safe conditions,
• defining, in said at least one segment of said movement trajectory, a safety trajectory alongside said movement trajectory at a distance substantially equal to said deviation,
• configuring an electric motor to move said operating assembly along at least a portion of said movement trajectory,
• arranging an auxiliary guide element at said safety trajectory,
• moving said operating assembly by said electric motor along at least a portion of said movement trajectory, and
• abutting said operating assembly with said auxiliary guide element to control the movement of said operating assembly by guiding it along said safety trajectory by said auxiliary guide element if, along said at least one segment of said movement trajectory, said operating assembly moves away from said movement trajectory by a distance equal to said deviation.

An apparatus for automatic processing of articles, comprising:

• an operating assembly configured to interact with an article of said articles and to perform said processing, and movable along a predefined movement trajectory,
• an electric motor configured to move said operating assembly along at least a portion of said movement trajectory,
• an auxiliary guide element alongside said movement trajectory at at least one segment of said movement trajectory,
• wherein said auxiliary guide element is:
• spaced from said movement trajectory by a distance equal to a deviation of said operating assembly from said movement trajectory such that said operating assembly can be moved in safe conditions, and
• configured to abut said operating assembly when said operating assembly moves away from said movement trajectory by a distance equal to said deviation, and to guide said operating assembly along a safety trajectory.
