Process for controlling the operation of machines for processing articles, for example for packaging food products, and the machine thereof

摘要

A process for controlling the operation of machines for processing articles includes the step of synchronously controlling the movement or speed of a feeding device and an intake branch of the machine. The process provides a method of adapting a processing machine to adjust to discontinuities in an otherwise continuous flow of articles being supplied to the machine for processing. The process provides for the speed of the feeding device and the speed of the intake branch to both be reduced simultaneously. The speed of the feeding device is slowed sufficiently that it obtains a minimum speed at the time that the perceived discontinuity reaches the interface of the feeding device and the intake branch. Simultaneously, the speed of the intake branch is reduced to a substantially standstill condition at the time that the feeding device obtains its minimum speed. The process may further provide for the standstill condition of the intake branch to be maintained until the first article, positioned after the detected discontinuity, reaches the intake branch. The process may then provide for the reactivation of the intake branch so as to bring the feeding device and the intake branch back to their normal operating conditions.
