Stabilising device for stabilising articles during raising and grouping of the articles

A stabilising device for stabilising articles during raising and grouping thereof, comprising:

• an abutting bar, configured and predisposed for being abutted by the articles which are raised upwards during operations for grouping thereof;
• a support element of the abutting bar;
• vertical sliding guides, the support element being predisposed so as to be coupled to the vertical sliding guides and in order to be able to freely slide along the vertical sliding guides so as to enable displacement upwards of the abutting bar pushed by the articles which are raised upwards during the operations for grouping thereof;
• a contact element, predisposed on the support element so as to be translatable with respect to the support element, activating means of the contact element, configured and predisposed so as to be able to be activatable for moving the contact element from a non-operative position, at which the contact element is distant from the vertical sliding guides, to an operative position, at which the contact element is in contact with at least one of the vertical sliding guides so as to provide a friction force resistant to the free sliding of the support element with respect to the vertical sliding guides and therefore provide a braking action to the movement of the abutting bar, the contact element comprising a through-hole,
• the activating means of the contact element comprising:
• a vertical rod, which is predisposed so as to coaxially cross the through-hole and which is pivoted to the relative ends so as to be activatable in rotation according to a rotation axis that is offset with respect to the relative axis and to the centre of the through-hole, and
• rotation activating means for activating the vertical rod in rotation about the offset rotation axis so that the rotation of the vertical rod in a rotation direction or another with respect to the offset rotation axis determines translation of the contact element with respect to the support element from the relative non-operative position to the relative operative position and vice versa.
