Abstract
A linear motor system includes a track and at least one movable member coupled to the track and configured to move along the track. The at least one movable member includes a first element, a second element relatively movable with respect to the first element, and at least one movement detector configured to transmit a movement signal. A processing unit is configured to calculate a movement of the movable member, the second element and/or the first element as a function of the movement signal received from the movement detector.
Claims21
A forming assembly configured to form a plurality of packages, the forming assembly comprising:
- a pair of endless tracks;
- a pair of movable members, each one of which movably coupled to, and cyclically movable along, one respective track;
- each movable member of said pair of movable members comprising:
- a coupling element configured to couple the movable member to the respective track,
- a second element, relatively movable so as to move linearly or angularly with respect to the coupling element and the respective track,
- a forming unit cyclically movable and configured to form the packages,
- wherein at least one movable member of the pair comprises at least one movement detector mounted on the second element and configured to transmit a movement signal indicative of movement of at least the second element, and
- wherein the forming assembly comprises a processing unit configured to calculate a movement of the second element as a function of the movement signal received from the movement detector.
A linear motor system, comprising:
- a track;
- at least one movable member coupled to the track and configured to move along said track, the at least one movable member comprising:
- a coupling element coupling the movable member to the track,
- a second element, relatively movable so as to move linearly or angularly with respect to the coupling element and the track, and
- at least one movement detector, mounted on the second element and configured to transmit a movement signal indicative of movement of at least the second element;
- and
- a processing unit, configured to calculate a position of the second element as a function of the movement signal received from the movement detector.
A movable member couplable to a track, the movable member comprising:
- a coupling element couplable to the track and configured to move along said track,
- a second element, relatively movable so as to move linearly or angularly with respect to the coupling element and the track,
- at least one movement detector mounted at the second element and configured to transmit a movement signal indicative of movement of at least the second element, and
- a processing unit configured to calculate a movement of the second element as a function of the movement signal received from the movement detector.
