Patent ID: 8328140

Claim:
A system for transportation of goods in a loading space, which system comprises at least one conveyor ( 1 ) running substantially parallel with the floor ( 2 ) of the loading space, intended to have goods placed on it and drivable to and fro in the loading space, wherein the conveyor ( 1 ) comprises: a first element ( 3 ) comprising a goods-bearing belt ( 5 ) and a wall ( 6 ) disposed transversely to the driving directions of the conveyor ( 1 ), the goods-bearing belt being fastened to the wall via a first end portion ( 5 a ) so that the wall serves as a stop for goods on the belt, the wall being movable by means of a drive device and drive means ( 14 , 15 ) between a first extreme position (A) at or in the vicinity of an aperture to the loading space via which goods can be loaded onto and unloaded from the conveyor, and a second extreme position (B) at a far end of the loading space from said aperture, and a second element ( 4 ) which is disposed at or in the vicinity of the aperture to the loading space as a continuation of said first element ( 3 ) of the conveyor ( 1 ) and to which the goods-bearing belt ( 5 ) is fastened via a second end portion ( 5 b ) which through at least one toothed strip ( 9 ) cooperates with two elongate rollers ( 7 , 8 ) forming part of said second element and supported for rotation in the loading space at a distance from one another and about which, during movement of said transverse wall ( 6 ) between said extreme positions (A, B), said good-bearing belt being unwindable and windable so that the instantaneously uppermost strand ( 5 c ) of the goods-bearing belt ( 5 ) wound about the rollers serves as a movable loading and unloading surface for goods between said rollers, and at least one ( 7 ) of said elongate rollers ( 7 , 8 ) being drivable in rotation by the drive device for moving the transverse wall ( 6 ) via the drive means ( 14 , 15 ), wherein said drive means extend from said transverse wall to said far end of the loading space and therefrom around the drivable roller ( 7 ) and from said drivable roller ( 7 ) back to said wall between said extreme positions (A, B), and wherein movement of the wall unwinds or winds the goods-bearing belt ( 5 ).
