An apparatus for collecting a flattened tubular box, for opening-out and transferring the tubular box towards a receiving station has a first member hinged to a frame, bearing first aspirating means. Second, third, and fourth hinged members and the frame forming a four-bar linkage. A fifth member, hinged to the fourth member, bears second aspirating means. An abutting member is arranged between the first member and the receiving station inferiorly of the tubular box. The apparatus is being designed such that when the tubular box is in the folding position, a second wall of the box can be intercepted by the second aspirating means and folded progressively with respect to the first wall, the first aspirating means disengage the first wall, and the box moved by the second aspirating means up to rest on the abutting member with a consequent complete opening-out of the tubular box. |

1. An apparatus (1) for collecting a tubular box (2) in a flattened configuration, opening-out the tubular box (2) and for transferring the tubular box (2) towards a receiving station (R) of the tubular box (2), comprising:
a store (15) for storing the tubular box (2) in a flattened configuration, the store (15) having an outlet (U) from which the tubular box (2) can be collected, the tubular box (2) comprising a first sheet (6) and a second sheet (7) which are in contact with one another or in close proximity to one another, the first sheet (6) being connected to the second sheet (7) at two common and opposite ends, the first sheet (6) being provided with a first wall and a second wall (9) which are separated from one another by a first fold line (11), the tubular box (2) in the flattened configuration being stored in the store (15) at a first angle (a) of inclination with respect to a horizontal plane (0) so that the first sheet (6) of the tubular box (2) is facing towards an outer side of the outlet such that the first wall (8) of the first sheet (6) is at a greater height or elevation than the second wall (9) with respect to the first fold line (11), the apparatus (1) further comprising: a frame (10) positioned in a vicinity of a box receiving station (R) and the outlet (U) of the store (15); a first member (21) which is hinged to the frame (10) at a first hinge axis (31) in a position below the outlet of the store (15), the first member bearing first aspirating means (17); a second member (22) hinged to the frame (10) at a second hinge axis (32); a third member (23) hinged to the frame (10) at a third hinge axis which coincides with the first hinge axis (31); a fourth member (24) hinged to the second member (22) at a fourth hinge axis (34) and to the third member (23) at a fifth hinge axis (35); the second member (22), the third member (23), the fourth member (24) and the frame (10) forming a four-bar linkage; a fifth member (25) having a first end, a second end, and a central portion and being hinged via the central portion to the fourth member (24) at a sixth hinge axis (36), the fifth member bearing second aspirating means (18) at the central portion thereof; a sixth member (26), which is hinged to the frame (10) at a seventh hinge axis which coincides with the first hinge axis (31) and the third hinge axis; and a seventh member (27), which is hinged to the sixth member (26) at an eighth hinge axis (38) and which is hinged to the first end of the fifth member (25) at a ninth hinge axis (39), the sixth member (26) and the seventh member (27) being configured to move the fifth member (25), an abutting member (20) for encountering the first wall (8) of the first sheet (6) of the tubular box (2), which abutting member (20) is arranged between the first member (21) and the receiving station (R) and is arranged inferiorly of or below the tubular box (2) when the tubular box (2) is in the folding position (P); the apparatus being configured such that: the first member (21) is rotatable to bring the first aspirating means (17) to intercept and retain the first wall (8) of the first sheet (6) at the outlet (U) of the store (15) and is further rotatable to collect and take out the tubular box (2) in flattened configuration from the outlet (U) of the store (15) and bring the tubular box (2) retained by the first aspirating means (17) downward into an unfolding position (P) which is below the outlet (U) of the store (15); when the tubular box (2) is brought into the unfolding position (P) and retained by the first aspirating means (17) in this unfolding position (P), the fifth member (25) is rotatable to bring the second aspirating means (18) to intercept and retain the second wall (9) of the first sheet (6) and then the first member (21) and fifth member (25) are further rotatable to move the first wall (8) and the second wall (9) to rotate the second wall (9) with respect to the first wall (8) about a hinge axis that coincides with the first fold line (11); and the first member (21) is further rotatable for disengaging the first aspirating means (17) from the first wall (8) and the fifth member (25) is further rotatable so that the tubular box (2) can be moved by the second aspirating means (18) from the unfolding position (P) up to coming to rest on the abutting member (20) with a consequent complete opening-out of the tubular box (2). |
