Patent ID: 7900915

Claim:
A device for the transport and the weighing of objects successively passing by the device, in particular letters, wherein the objects extend in a first direction (X) and a second vertical direction (Z) perpendicular thereto, with a surface facing a third direction (Y) perpendicular to the X and Z directions, and wherein the objects are conveyed, coming from a supply device, with a front edge in the lead, an upper edge facing upwards, a lower edge facing downwards and a rear edge facing away from the conveyance device, to an immediately following transport unit, the device further comprising: a) a transport unit coupled as a preload to a weighing cell in order to detect the weight of the objects by means of the weighing cell during further conveyance; b) the transport unit comprising at least two opposing transport elements that form a nip in order to convey an object between them, and of which at least one transport element is drivable; c) the spatial dimensions of the transport elements of the transport unit that form the nip circumscribing a space in the X, Y, and Z directions; d) wherein the transport unit is constructed to take up the object starting with its front edge in order to convey it further; and e) wherein at least one of one or more guide elements is provided outside the space, which applies a guidance force to the object in the direction Y perpendicular to the directions X and Z in order to avoid a lateral deflection or fluttering of the object, particularly in the area of its edges, when the transport unit has seized or drawn in the object at its front edge.
