Abstract:
1. An apparatus for inserting articles internally of boxes, which apparatus is operable in synchrony with a first conveyor and a second conveyor, the apparatus comprising: a frame positionable by a side of the first conveyor which moves articles in an advancement direction and in a horizontal advancement direction, with the second conveyor arranged by a side of the first conveyor; which moves boxes in a same advancement direction as the first conveyor a first thrust plate for pushing at least an article into a box; a first abutting blade for at least partially entering the box and providing an upper abutment for facilitating insertion of the article into the box; a first member hinged to the frame at a first hinge axis; a second member hinged to the first member at a second hinge axis; a third member hinged to the frame at the first hinge axis; a fourth member hinged to the second member at a third hinge axis and to the third member at a fourth hinge axis; the first member, the second member, the third member and the fourth member defining a first four-bar linkage; a fifth member hinged to the fourth member and to the second member at the third hinge axis; a sixth member hinged to the fifth member at a fifth hinge axis; a seventh member hinged to the sixth member at a sixth hinge axis and to the fourth member and to the third member at the fourth hinge axis; the fourth member, the fifth member, the sixth member and the seventh member defining a second four-bar linkage; an eighth member hinged to the frame at a seventh hinge axis and to the seventh member at an eighth hinge axis; the first hinge axis, the second hinge axis, the third hinge axis, the fourth hinge axis, the fifth hinge axis, the sixth hinge axis, the seventh hinge axis and the eighth hinge axis being horizontal and perpendicular to the advancement direction; the apparatus being positionable with respect to the first conveyor such that the second member is downstream of the third member with respect to the advancement direction; a first linear motor borne by the fifth member; a second linear motor borne by the fifth member; a first rod fixed to the first thrust plate and being moved by the first linear motor so as to move with an alternating motion in a horizontal and perpendicular direction to the advancement direction; a second rod fixed to the first abutting blade and being moved by the second linear motor in order to move with an alternating motion in a horizontal and perpendicular direction to the advancement direction; the first member and the third member being rotatable to move the fifth member in synchrony with the first conveyor and with the second conveyor and enable movement of the first thrust plate and the first abutting blade respectively by the first linear motor and the second linear motor in order to introduce at least an article internally of the box.
