Machine and method for filling containers
First Claim
1. A machine for filling containers, each container having a longitudinal axis, the machine comprising:
- a conveying device;
at least one handling unit configured to be fed by the conveying device along a transfer path, the at least one handling unit including a support device configured to receive and retain a container and at least one filling device selectively activated for feeding a pourable product into the container while the at least one handling unit travels along the transfer path;
a pressurizing circuit selectively in communication with the container advancing along the transfer path to feed an operative fluid that is pressurized at a pressure higher than atmospheric pressure into the container;
a decompression circuit selectively in communication with the container advancing along the transfer path to discharge excess pressure with respect to the atmospheric pressure, after completion of the filling of the container with the pourable product;
at least one actuating device selectively switched to an active state to rotate the container about the longitudinal axis while the container is advanced along the transfer path; and
a control unit configured to;
control activation and deactivation of the at least one filling device and the at least one actuating device;
control connection of the pressurization circuit and the decompression circuit with the container; and
simultaneously maintain the at least one actuating device in an active state while the decompression circuit is in communication with the container so as to rotate the container about the longitudinal axis during decompression.

Abstract
A machine for filling containers, each container having a longitudinal axis, the machine comprising: a conveying device; at least one handling unit including a support device configured to receive and retain a container and at least one filling device selectively activated for feeding a pourable product into the container while the at least one handling unit travels along the transfer path; a pressurizing circuit; a decompression circuit; at least one actuating device; and a control unit configured to: control activation and deactivation of the at least one filling device and the at least one actuating device; control connection of the pressurization circuit and the decompression circuit with the container; and simultaneously maintain the at least one actuating device in an active state while the decompression circuit is in communication with the container so as to rotate the container about the longitudinal axis during decompression.

14. A method for filling containers, each container having a longitudinal axis, the method comprising:
-
advancing at least one handling unit along a transfer path; feeding a container to the handling unit to be retained and advanced along the transfer path; filling the container with a pourable product by activating at least one filling device of the handling unit while the handling unit is advanced along the path; pressurizing the container to a pressure higher than atmospheric pressure while the handling unit is advanced along the transfer path; performing decompression of the container by discharging excess pressure with respect to the atmospheric pressure while the handling unit is advanced along the transfer path and after completion of the filling of the container with the pourable product; and rotating the container about the longitudinal axis during decompression. - View Dependent Claims (15, 16, 17, 18)
