Automatic packaging machine (3) for filling a bag (1) made of heat-sealable material, having an open upper end (2) with a dose of loose product; the packaging machine (3) has: a packaging conveyor (4); a pick-up head (7), which is supported by the packaging conveyor (4) to advance along a packaging path (P1); an input station (S1) where the empty bag (1) is grabbed by the pick-up head (7); an output station (S2) where the full, sealed bag (1) leaves the pick-up head (7); a filling device (18) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to supply the dose of product inside the bag (1) through the upper open end (2); and a sealing device (19) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to seal the full bag (1) through a heat-seal in correspondence with the open upper end (2).

Method to move containers (C) in a processing line (10) that comprises a station (11) for storing and picking up said containers (C) and a station (12) at least for filling said containers (C), said method providing, in said storage and pick-up station (11), to supply a container-holding tray (15) containing a plurality of said containers (C) disposed upended in said container-holding tray (15) with respect to their mouth (43), and subsequently to upend said containers (C) with the aid of upending means (20) so as to invert the orientation of said containers (C) and make them available with the side of the mouth (43) facing upward so that they can be picked up by extraction means (22).

A movement unit for articles includes a first carousel device having a first transporter member and first gripping heads mounted thereon and provided to move the articles into a single-row configuration. The movement unit further includes a second carousel device to receive the articles from the first carousel device, having a second transporter member and second gripping heads mounted thereon. Each second gripping head is configured to receive the articles from a respective first gripping head and to move the articles into a multi-row configuration.

The present invention relates to a method of packaging a set of stacked lids, which includes the steps of capturing an empty, flat package (12), comprising an inlet (25), by securing a vacuum terminal (8) in the immediate proximity of the inlet (25) of the package (12) and maintaining this package (12) straight; maintaining the vacuum terminal (8) activated, retaining the package (12), and producing an air jet towards the inlet (25) of the package (12) so as to open the inlet (25) of the package (12); maintaining a vacuum terminal (8) activated, retaining the package (12) and fitting the inlet (25) of the package (12) thus opened in a feed nozzle (5); transferring into the package (12) a set of stacked lids (6), the set of lids (6) passing through the feed nozzle (5) and the inlet (25) of the package (12) to the interior of the package (12).

The present invention also relates to a packaging device for sets of stacked lids.

A container filling apparatus of the present invention includes: a first supply apparatus configured to supply a content; a rotational body having a placement portion configured to carry the contents supplied by the first supply apparatus, the rotational body being configured to rotate with respect to an axis thereof to turn the placement portion; a second supply apparatus configured to place a container from above on the content placed in an upward-facing state on the placement portion; and an engagement portion provided on the rotational body and configured to engage with the container that is placed over the content by the second supply apparatus, wherein the container is disengageable from the engagement portion by the container being rotated by the rotational body at an angle.

A horn and an anvil are moved toward and away from each other by axially reciprocating a driving rod and thereby reciprocatingly rotating a forked lever in a predetermined angle range. The horn and the anvil are moved toward and pressed against each other with a predetermined force with a bag mouth b held therebetween. A sensor detects the position of a second mounting block secured to the rear end of a sliding shaft of the anvil, thereby detecting the distance between respective pressing surfaces of the horn and the anvil, i.e. the thickness m of a portion of the bag mouth held between the pressing surfaces. When the thickness m is not less than a predetermined threshold value M, a vibrator is activated to perform sealing. When the thickness m is less than the threshold value M, no sealing is performed.
