摘要： There is described package distribution apparatus (1) comprising an upstream conveying device (3) configured to advance a succession of packages (2) along an upstream advancement path (P) and a distribution device (4) configured to selectively distribute the packages (2) advancing along the upstream advancement path (P) into a first flow (F1) of packages (2) advancing, in use, along a first downstream path (Q) and a second flow (F2) of packages (2) advancing, in use, along a second downstream path (R). The distribution device (4) comprises an endless carrier (15), a plurality of independent carts (16) moveably coupled to the endless carrier (15) and an actuation unit (17) configured to selectively advance the carts (16) along the endless carrier (15) and along an endless path (S). Each cart (16) comprises a pushing element (18) configured to interact with one or more respective packages (2) while the respective cart (16) advances, in use, along a contact portion (19) of the endless carrier (15) for directing the one or more respective packages (2) onto the second downstream path (R). The contact portion (19) is designed such that each pushing element (18) advances along a rectilinear path (T1) when directing, in use, the respective one or more packages (2) onto the second downstream path (R).

摘要： There is described a method for controlling a plurality of carts (8) movable independently from one another along an endless track (7) and configured to perform at least one task in order to carry out at least one operation onto respective articles (3); the method comprising the steps of:
a) advancing the carts (8) along the track (7), the track (7) comprising at least one task section (13) and at least one transient section (14);
b) advancing each cart (8) along a task-assignment section (16) of the track (7) arranged upstream of the at least one task section (13);
c) advancing a plurality of articles (3) along a feeding path (Q) and through an operation station (A) at which the operation is carried out;
d) detecting the passage of each article (3) at a detection station (D) of the feeding path (Q) located upstream of the operation station (A); and
e) controlling one respective cart (8) to perform the at least one task if an article (3) is detected, during the step d) of detecting, when the cart (8) is moving along the task-assignment section (16).-

摘要： A method (400) for controlling a regulating valve (206) of a packaging machine (100), wherein the packaging machine (100) is a roll-fed packaging machine configured to receive a roll of a carton-based packaging material (102). The packaging machine (100) is configured to be connected to a processing line (202) via the regulating valve (206), wherein the processing line (202) is configured to feed a liquid food product (216) to the packaging machine (100) through the regulating valve (206). The method (400) comprises determining (S402) a product flow, using a flow meter (106), of the liquid food product in the packaging machine (100); determining (S404) an inlet pressure-measurement (306), using a pressure sensor (204), of the liquid food product in the packaging machine (100); and making use of the inlet pressure measurement to the packaging machine (100) for adjusting the regulating valve (206), said regulating valve being configured to receive an output signal from a flow feed forward module (308) in combination with an output signal from a flow proportional-integral-derivative (PID) module (310), wherein the flow feed forward module (308) has the inlet pressure measurement (306) and a flow set point as input signals, and wherein the flow PID module (310) has the product flow and the flow set point as input signals.

摘要： A method for controlling a flow regulating valve (6) of a filling machine (1) forming composite packages (2) from a multilayer composite packaging material and filling the composite packages with a pourable filling product, wherein a position of the regulating valve controls the flow of the product filling the packages, the method envisages: implementing a flow feedback control, receiving a flow set point (F SP ) and an inlet flow measurement (F IN ) and generating a feedback control contribution (C FB ) indicative of a difference between the inlet flow measurement and the flow set point; implementing a flow feed-forward control, receiving the flow set point (F SP ) and generating a feedforward control contribution (C FF ) using fluid-dynamic maps, which map an output position of the regulating valve with respect to flow and pressure values of the filling product; generating a virtual pressure (Pv) based on the feedback control contribution (C FB ) generated at the output of the flow feedback control module, wherein the flow feedforward control receives the virtual pressure (Pv) and generates at its output the feedforward control contribution (C FF ) based on the flow set point (F SP ) and the virtual pressure (P V ) using the fluid-dynamic maps. The feedforward control contribution (C FF ) determines a control signal (S c ) for adjusting an operating position of the flow regulating valve (6).
