Abstract

Abstract An apparatus for handling palletized goods stacked in tiers consists of a pivoted cradle having two substantially perpendicular supports for the goods, one of said supports normally constituting a horizontal loading plane and the other a vertical supporting plane, said planes being adapted alternatingly to support the goods due to the pivoting movement of the cradle. According to the invention the supporting plane is composed of a plurality of carriages which are movable towards and away from the loading plane in such a way that the various tiers are separable from each other when supported by the supporting plane formed of the carriages.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 197 words
Apparatus for handling palletized goods and the like stacked in tiers, said apparatus consisting of a pivoted cradle (1) having two supports (2, 3) for the goods substantially perpendicular to each other, one of said supports normally constituting a horizontal loading plane (2) and the other a vertical supporting plane (3), said planes being adapted alternatingly to support the goods due to the pivoting movement of said cradle (1), characterized in that said supporting plane (3) is composed of a plurality of parts in the form of carriages (9) which are movable towards and away from said loading plane (2) in such a way that the various tiers (10) are separable from each other when supported by the supporting plane formed of the carriages (9), said carriages (9) cooperating with a drive mechanism (16-18) which is adapted to impart to said carriages (9) such a displacing movement that the relative distance between said carriages (9) is always the same, the supporting plane of said carriages (9) comprising two legs (21, 22) directed at right angles to each other, one (22) of which makes 30°-45° with the axis of rotation (4) or the like of said cradle (1).
Claim 2
Dependent Claim 197 words
Apparatus for handling palletized goods and the like stacked in tiers, said apparatus consisting of a pivoted cradle (1) having two supports (2, 3) for the goods substantially perpendicular to each other, one of said supports normally constituting a horizontal loading plane (2) and the other a vertical supporting plane (3), said planes being adapted alternatingly to support the goods due to the pivoting movement of said cradle (1), characterized in that said supporting plane (3) is composed of a plurality of parts in the form of carriages (9) which are movable towards and away from said loading plane (2) in such a way that the various tiers (10) are separable from each other when supported by the supporting plane formed of the carriages (9), said carriages (9) cooperating with a drive mechanism (16-18) which is adapted to impart to said carriages (9) such a displacing movement that the relative distance between said carriages (9) is always the same, the supporting plane of said carriages (9) comprising two legs (21, 22) directed at right angles to each other, one (22) of which makes 30°-45° with the axis of rotation (4) or the like of said cradle (1).
Claim 3
Dependent Claim 35 words
Apparatus as claimed in claim 1, wherein the outermost carriage (9) as counted from the loading plane (2) is connected to a frame (11) for a cover (12) hingedly mounted thereto for the stacked goods.
Claim 4
Dependent Claim 39 words
Apparatus as claimed in claim 1 or 2, wherein the loading plane (2) is provided with a fixed support (14) for the pallet (15), said support (14) being of at least generally the same shape as the carriages (9).
Claim 5
Dependent Claim 26 words
Apparatus as claimed in claim 1, wherein the drive mechanism (16-18) includes a shear mechanism (16) the junctions (17) of which cooperate with the carriages (9).
Claim 6
Dependent Claim 27 words
Apparatus as claimed in claim 4, wherein the shear mechanism (16) is acted upon by a hydraulic piston (18) or the like for driving the carriages (9).
Claim 7
Dependent Claim 28 words
Apparatus as claimed in claims 1, 2, 4 or 5, wherein the carriages (9) are adapted to be displaceable along common guides (19) secured in the cradle (1).
Claim 8
Dependent Claim 34 words
Apparatus as claimed in claim 6, wherein bars (20) extending in parallel with the guides (19) are arranged in the supporting plane of the carriages (9) to support goods situated between the carriages (9).
Claim 9
Dependent Claim 24 words
Apparatus as claimed in claims 1, 2, 4, 5 or 7, wherein the supporting plane of the carriages (9) is generally semicircular in cross-section.
