Column for equipment for stacking and transporting piled-up articles
A column for equipment for stacking and transporting piled-up and vertically separated articles includes a plurality of superimposed swingable brackets suitable to support the articles and associated to respective counter-weights. The central section of each of the brackets has a pair of ears for a pivot pin and a pair of stop fins inserted in respective grooves provided for on the body of the column. The rear section of each of the brackets is provided with at least one lateral appendage coupled with two counter-weights one of which is connected to the lateral appendage of the underlying bracket and the other of which is connected to the lateral appendage of the overlying bracket.
1. A column for equipment for stacking and transporting piled-up and separated articles, comprising:
a channel-shaped body, a plurality of superimposed swingable brackets designed to support the articles, said brackets being formed by a front section for supporting the articles, a central section for coupling with said body and a rear section, each one of said brackets being pivoted to the body so as to be rotated between a retracted inoperative position, in which it is substantially contained inside the body, an intermediate pre-loading position, in which the front section of the bracket is partially projecting from the body to receive an article, and an extracted loading position in which said front section is projecting substantially transversely from said body to support the article, wherein the central section is provided with means for pivoting to the body and wherein there are provided for actuator means for controlling the rotation of the bracket from the retracted position to the intermediate pre-loading position by a contiguous bracket and means for returning the bracket towards the retracted inoperative position,
the central section of each of the brackets having a pair of stop fins coplanar to the central section, each of the stop fins being inserted into a respective groove provided for on the body, said groove being formed by:
an initial section with a substantially horizontal lower surface on which the stop fin rests in said loading position of the bracket,
an end section with a vertical surface against which the stop fin rests in said inoperative position of the bracket, and
a slanting chute intermediate section suitable to allow the stop fin to pass through—during the rotation of the bracket between said inoperative and loading positions,
and the rear section of each of the brackets provided with at least one lateral appendage coupled to said actuator means.
2. A column according to claim 1 , wherein said central section has a pair of ears projecting downwards and provided with holes for a pivot pin inserted into a respective pair of holes provided on the body and defining said pivot means.
3. A column according to claim 1 , wherein said central section has a pair of coplanar fins projecting on opposite sides and bearing respective bushings inserted in a respective pair of holes ( 21 ) provided on the body ( 2 ) and defining said pivot means.
4. A column according to claim 2 , wherein said actuator means and said return means comprise respective counter-weights.
5. A column according to claim 3 , wherein said actuator means and said return means respectively comprise a cam member carried by said lateral appendage and a spring associated to one of said coplanar fins.
6. A column according to claim 4 , wherein said return means comprise two counter-weights respectively lower and upper, and each counter-weight has an upper hole and a lower slot, wherein
the lower counter-weight is connected to the lateral appendage of the bracket by means of the respective upper hole and to the lateral appendage of an underlying bracket by means of the respective lower slot, and
the upper counter-weight is connected to the lateral appendage of the bracket by means of the respective lower slot and to the lateral appendage of an overlying bracket by means of the respective upper hole-.
7. A column according to claim 1 , further comprising a longitudinal bar slidable in said body and having a row of openings which, in a raised locking position of said bar, are suitable to be engaged with said lateral appendages of the brackets so as to prevent the movement thereof.
8. A column according to claim 7 , wherein said longitudinal bar is actuated by the contiguous bracket of the plurality of superimposed brackets.
9. A column according to claim 1 , wherein the rear section of each of the brackets is inclined with respect to said central section.
10. A column according to claim 1 , wherein the front section of each of the brackets is covered with an anti-skid and/or anti-scratch material.
11. Equipment for stacking and transporting piled-up articles, comprising at least two columns according to claim 1 .
12. Equipment according to claim 11 , wherein said columns are vertical and said brackets in said extracted position extend horizontally.
13. Equipment according to claim 11 , wherein said columns are horizontal and said brackets in said extracted position extend horizontally.
14. Equipment according to claim 11 , wherein said columns are horizontal and said brackets in said extracted position extend vertically.
15. Equipment according to claim 11 , wherein said columns are inclined and said brackets in said extracted position extend vertically.
