Abstract
Abstract The invention relates to a machine for loading packages on a pallet, of the kind in which the successive layers of packages are introduced from the bottom. Said machine comprises, in combination, an area for stacking the packages in layers, constituted by parallel rollers, means for bringing the packages on to the said area, two means for lifting the load of packages during the course of operation through a height sufficient to permit the sliding under the said load of a layer of packages, each of the said lifting means acting in its turn, a horizontal translation means imparting a relative movement of translation between the whole of the said two lifting means and the said stacking area, and lateral retention means for the load of packages during the course of operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
A machine for loading packages on a pallet, of the kind in which the successive layers of packages are introduced from the bottom, characterized in that it comprises, in combination, and area for stacking the packages in layers and having parallel rollers, means for bringing the packages onto the said area, two lifting means facing each other on each side of said stacking area for continuously lifting successive layers wherein one layer is lifted by one of said lifting means through a height sufficient to permit another layer of packages to be slid under the first layer, the other layer is lifted by the other lifting means when said first lifting means is withdrawn depositing said first layer on said other layer, said first lifting means then returning to lift a successive layer and lateral retention means for stripping the layer off each of the lifting means as the lifting means is withdrawn.
Claim 2
Dependent Claim
153 words
A machine for loading packages on a pallet, of the kind in which the successive layers of packages are introduced from the bottom, characterized in that it comprises, in combination, and area for stacking the packages in layers and having parallel rollers, means for bringing the packages onto the said area, two lifting means facing each other on each side of said stacking area for continuously lifting successive layers wherein one layer is lifted by one of said lifting means through a height sufficient to permit another layer of packages to be slid under the first layer, the other layer is lifted by the other lifting means when said first lifting means is withdrawn depositing said first layer on said other layer, said first lifting means then returning to lift a successive layer and lateral retention means for stripping the layer off each of the lifting means as the lifting means is withdrawn.
Claim 3
Dependent Claim
19 words
A machine in accordance with claim 1 characterized in that a horizontally-sliding plate carries the said two lifting means.
Claim 4
Dependent Claim
35 words
A machine in accordance with claim 2, and further characterized in that vertical members rigidly fixed to the said plate serve for the vertical displacements of the said lifting means which are constituted by forks.
Claim 5
Dependent Claim
18 words
A machine in accordance with claim 1 characterized in that a horizontally-sliding frame carries the said stacking area.
Claim 6
Dependent Claim
30 words
A machine in accordance with claim 4, and further characterized in that fixed vertical members serve for the vertical displacement of the said lifting means, which are constituted by forks.
Claim 7
Dependent Claim
94 words
A machine in accordance with claim 1, characterized in that separating means permit the said lateral retention means to be moved father apart at the moment of evacuation of the load of packages, cam devices operatively connected with said separating means for controlling said separating means, supports and horizontal arms sliding horizontally in the said supports and carrying said lateral retention means, said arms being actuated in such manner as to adjust very rapidly the width of the load by means of said lateral retention means and to compact the load at each layer.
Claim 8
Dependent Claim
36 words
A machine in accordance with claim 1, characterized in that two supplementary means articulated on the said lateral retention means enable compacting of a layer of packages and the centering of a pallet to be effected.
Claim 9
Dependent Claim
40 words
A machine in accordance with claim 1, characterized in that it is associated with an aerial distributor of bare pallets permitting the formation of unit loads of packages of different qualities and dimensions on pallets of different qualities and dimensions.
