Patent

CA 2608648

A scoring bridge includes a plurality of moveable mounted carriages. The carriages each have a rotor, and the bridge has a linear stator to move the carriages. The position of a carriage designated as a reference carriage is recorded as it moves past a motion detector. The position of each remaining carriages is recorded as they individually move past the detector. The difference between the position of a carriage and the position of the reference carriage is an offset that is added to the position reading of the carriage to accurately space the carriage form the reference carriage. Each of the carriages can have a scoring assembly that includes servomotor acting through a gear arrangement on a scoring wheel. The servomotor applies a constant load to the scoring wheel and adjusts the load for any positive or negative displacement of the scoring wheel from a reference position.

La présente invention a trait à un pont de rayage comportant une pluralité de chariots montés mobiles. Les chariots comportent chacun un rotor, et le pont comporte un stator linéaire pour le déplacement des chariots. La position d'un chariot désigné comme chariot de référence est enregistrée lors de son passage devant un détecteur de mouvement. La position de chacun des autres chariots est enregistrée lors de leur passage individuel devant le détecteur. La différence entre la position d'un chariot et la position du chariot de référence constitue un décalage qui est ajouté au relevé de position du chariot en vue d'un espacement précis du chariot par rapport au chariot de référence. Chacun des chariots peut comporter un ensemble de rayage comprenant un servomoteur fonctionnant à travers un engrenage sur la molette. Le servomoteur assure l'application d'une charge constante à la molette et ajuste la charge pour tout déplacement positif ou négatif de la molette à partir de la position de référence.
