Abstract
Abstract A system for the transfer of loads from a wheeled transporter to a roller conveyor. The system includes two transfer conveyors which are arranged in alignment with a roller conveyor supplying a machine. Strips are provided on the wheeled transporter which form spaces therebetween to receive bars which project laterally from a pallet on the wheeled transporter. The pallet can be raised and lowered so that the bars can be moved onto the two transfer conveyors to facilitate transfer of the loads from the wheeled transporter to the two transfer conveyors which in turn transfers the loads to the roller conveyor or supply of the machine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
A system in particular for transferring loads from a wheeled transporter on which they are carried on a pallet in a palletised condition, to a roller conveyor on which they are to be disposed in a loose condition, comprising: two transfer conveyor means arranged in alignment with said roller conveyor, said two transfer conveyor means being parallel to the longitudinal axis of said roller conveyor and movable to the same height as said roller conveyor, and said two transfer conveyor means being mutually spaced at a distance sufficient to permit the passage therebetween of said wheeled transporter carrying the palletised loads; strips on said wheeled transporter forming a conventional platform portion for the loads carried in the palletised condition, said strips having therebetween spaces, a series of bars adapted to be received in said spaces, said two transfer conveyor means being intended to co-operate with said series of bars which, before the transfer step, are slid below the loads, into said spaces between said strips forming said platform portion of the pallets which carry the loads, and means varying the relative height between said transporter and said two transfer conveyor means, the length of said bars being such that they project laterally from the pallet and that they can come into a position of bearing onto said two transfer conveyor means after the relative height as between the wheeled transporter and said two transfer conveyor means has been suitably varied.
Claim 2
Independent Claim
240 words
A system in particular for transferring loads from a wheeled transporter on which they are carried on a pallet in a palletised condition, to a roller conveyor on which they are to be disposed in a loose condition, comprising: two transfer conveyor means arranged in alignment with said roller conveyor, said two transfer conveyor means being parallel to the longitudinal axis of said roller conveyor and movable to the same height as said roller conveyor, and said two transfer conveyor means being mutually spaced at a distance sufficient to permit the passage therebetween of said wheeled transporter carrying the palletised loads; strips on said wheeled transporter forming a conventional platform portion for the loads carried in the palletised condition, said strips having therebetween spaces, a series of bars adapted to be received in said spaces, said two transfer conveyor means being intended to co-operate with said series of bars which, before the transfer step, are slid below the loads, into said spaces between said strips forming said platform portion of the pallets which carry the loads, and means varying the relative height between said transporter and said two transfer conveyor means, the length of said bars being such that they project laterally from the pallet and that they can come into a position of bearing onto said two transfer conveyor means after the relative height as between the wheeled transporter and said two transfer conveyor means has been suitably varied.
Claim 3
Dependent Claim
52 words
A system according to claim 1, wherein said wheeled transporter includes: legs; and, said varying means includes hydraulic lifting means for providing said transporter with a raised position corresponding to a load-transporting position thereof, and a lowered position corresponding to a load-transferring position in which said wheeled transporter rests on said legs.
Claim 4
Dependent Claim
17 words
A system according to claim 1, wherein said varying means includes means for raising or lowering same.
Claim 5
Dependent Claim
19 words
A system according to claim 1, wherein said two transfer conveyor means are slightly inclined relative to the horizontal.
Claim 6
Dependent Claim
70 words
A system according to claim 1, 2, 3 or 4, wherein: said two conveyor means are longitudinally spaced from said roller conveyor, so as to leave a sufficiently wide gap for the bars to pass therethrough, when they arrive at the end of said two conveyor means, and said gap being sufficiently narrow not to impede the movement of the load from said two conveyor means to said roller conveyor.
