Abstract: In a production line where various operations have to be performed on a unit that is conveyed through or assembled in the line, a control system for a set of actuators is provided that operates in discrete steps to carry out movement in a machine and is required to synchronize at points in speed and position. A controller is provided for each actuator, and a coordinator configured to determine or receive the position of the actuators and to receive or generate data concerning a waypoint, being positions and corresponding speeds for the actuators. The controllers are configured to change the speed of the actuators, and the coordinator starts the movement of at least one actuator on the basis of a point reached by another actuator, so as to achieve the desired synchronization.

Abstract: A labelling device includes a linearly displaceable piston operably connectable to a moving mechanism for moving the piston from a resting position to a labelling position. A label carrying mechanism is arranged at the distal end of the piston for carrying an adhesive label and affixing the adhesive label to an object via physical contact at the labelling position of the piston. A force-switching-state system is provided to maintain the piston in relation to the moving mechanism in an attracting force state and the piston moves with the moving mechanism. The physical contact creates an opposite repelling force from the object onto the label carrying mechanism causing separation of the displaceable piston from the moving mechanism. This separation causes a change of the force state of the displaceable piston from an attracting to a repelling force state, causing the linearly displaceable piston to move back to the resting position.
