Abstract:
1. A rotary labelling machine comprising: a carrousel to be pivotally driven by a carrousel motor; a plurality of container stations supported by said carrousel, wherein each container station comprises a container-holding plate and a plate motor suitable to rotate the plate about its own axis, control means suitable to control the movement of the plates as a function of the movement of the carrousel, wherein said control means comprise carrousel sensor means suitable to detect the movement of the carrousel and to generate a reference signal representative of a movement parameter of the carrousel; a plurality of local control units, each being connected with one of the plate motors, respectively, and being arranged in the vicinity of the plate motor or within a housing thereof and configured to receive and process said reference signal and generate a specific local control signal for said motor as a function of the reference signal; signal propagation means connected between the carrousel sensor means and each of the local control units and configured such that, when the labelling machine is working, the propagation means receive the reference signal from the carrousel sensor means and propagate said same reference signal to each of the local control units, wherein each of the local control units comprises a processor and a memory data-connected with the processor, the processor being configured to generate said specific local control signal as a function of the reference signal and data and/or specific control programs residing in said memory.
