Abstract
A device for positioning an article (2) to be wrapped by a machine has a horizontal support body (3) centrally fixed on a vertical rotation shaft (4). The device (1) is equipped with at a least one plier device (5) connected, to turn together with the rotation shaft, to support the body (3), the plier device provided with at least two jaws (6,7). An opening apparatus (8) is connected to at least one of the jaws (6,7) to hold and to release the article (2). The at least one plier device (5) is connected to the support body (3) by a respective rotation device (9) for rotating the at least one plier device (5) and of the article held thereby, around an axis almost radial in respect to the support body (3).

Device for positioning an article (2) to be wrapped by a machine comprising:
- a support body (3) centrally fixed on a vertical rotation shaft (4), the device (1) being equipped with at least one pliers means (5) connected to the support body (3) to turn together with the support body (3), the at least one pliers means provided with at least two jaws (6, 7) opening means (8) connected to at least one of the jaws (6, 7) for moving the at least one pliers means to hold and to release the article (2), the at least one pliers means (5) being connected to the support body (3) by means of respective rotation means (9) for the rotation of said at least one pliers means (5) and of the article held thereby, around an axis almost radial in respect to the support body (3), such that when the article is in a predetermined inlet position facing the at least one pliers means (5), the article is positioned between opened jaws (6, 7) of said pliers means, said jaws hold the article following closure of the at least one of the jaws (6, 7) operated by the opening means (8);
- the support body (3) and the rotation means (9) rotate the at least one pliers means (5) and the article (2) respectively around a vertical axis and a radial axis of the support body until the article reaches a predetermined position and a predetermined outlet orientation;
- such that when said position and orientation are reached, the opening means (8) open the at least one of the jaws (6, 7) releasing the article, and,
- wherein at least one first jaw (6) is hinged to one end of a shaped arm (14) by a first pivot (16), an opposite end of the shaped arm (14) forming a first joint (17) with a second joint pin (18) provided on an external end of a rod means (19), the rod means axially driven by first cam means (20).

- the support body (3) and the rotation means (9) rotate the at least one pliers means (5) and the article (2) respectively around a vertical axis and a radial axis of the support body until the article reaches a predetermined position and a predetermined outlet orientation;
- such that when said position and orientation are reached, the opening means (8) open the at least one of the jaws (6, 7) releasing the article,
- wherein the rotation means (9) comprise a rotating element (10) connected to the support body (3) by means of a first connection means (11) provided with bearings (30) for the free rotation of said rotating element (10) around a radial axis;
- said rotating element (10) having transmission means (12) for moving the rotating element around the radial axis and transmitting said rotary motion to the support means (13) for the pliers means (5), and,
- wherein the transmission means (12) of the rotating element (10) comprise a first gear wheel engaged to a respective gear sector (31) fixed to an end of a respective oscillating arm (32) whose remaining end has an idle wheel (33) constrained between sidewalls of a groove (34) of a second cam means (35) in a rotating member (36) coaxial in respect to the rotation shaft (4).
