Device for transferring mail bins

A transfer device for a linear conveyor, the transfer device comprising a fixed framework placed on one side of the linear conveyor, and an object transporter structure for moving objects towards the framework in a transfer direction that is different from the conveying direction of said conveyor, said transporter structure extending across the linear conveyor and in the transfer direction on one side of the conveyor, said transporter structure being mounted in said framework to move in a substantially vertical direction in order to occupy a transfer position in which the transporter structure is disposed above the linear conveyor or a retracted position in which the transporter structure is disposed below the linear conveyor, wherein said framework forms two substantially parallel and horizontal margins on said side of the conveyor, between which the transporter structure can be raised and lowered, the transporter structure being disposed below the two margins when it occupies its retracted position, and above the two margins when it occupies its transfer position, and wherein the two margins are offset in the vertical direction so that an object placed on the transporter structure rests on the two margins so that it is tilted when the transporter structure is in its retracted position.
