1. A weighing station for weighing and sorting objects to be weighed, the weighing station comprising: a) a load receiver for picking up a gravity force to be applied in a load transfer direction;b) a support element borne by the load receiver for temporarily holding and weighing at least one object;c) a conveyor element which, during or after the weighing step, rotates about an axis for transporting the at least one object from a weighing position on the support element;d) said conveyor element comprising a number of segmented areas that are disposed about the axis of the conveyor element in such a manner that during the weighing step, the at least one object to be weighed comes to lie in a respective segmented area;e) said conveyor element adapted to be rotated, in a conveying step, by a specifiable angle of rotation about its axis to transport the at least one object from the weighing position; andf) wherein the axis of the conveyor element forms an angle (β)<90° with the load transfer direction and wherein the conveyor element is further adapted to, as the at least one object is transported from the weighing position by the conveyor element, transport said object into a selected one of at least two different discharge areas adjacent to the conveyor element. 2. The weighing station of claim 1, wherein the axis of the conveyor element runs parallel to the load transfer direction. 3. The weighing station of claim 1, wherein the conveyor element is further adapted such that during the transport, a selected segmented area of the conveyor element sweeps over an area of the support element in which the at least one object to be weighed is located. 4. The weighing station of claim 3, wherein the segmented areas of the conveyor element are disposed about the axis of the conveyor element in such a manner that after one concluded conveying step, a subsequent, adjacent, segmented area is available for the further transport of a next object. 5. The weighing station of claim 1, wherein the segmented areas are uniformly spaced about the axis of the conveyor element and that the angle of rotation meets the requirement (α)=360°/n, where the angle of rotation a corresponds to the angle that is defined by each segmented area relative to the axis of the conveyor element. 6. The weighing station of claim 1, wherein the selection of the discharge area is defined by a speed of the conveyor element. 7. The weighing station of claim 1, wherein the transport into the first discharge area can be determined by the rotation of the conveyor element about its axis in a first direction of rotation while the transport into the second discharge area can be determined by the rotation of the conveyor element in the opposite direction of rotation. 8. The weighing station of claim 1, wherein the support element substantially has the shape of a downwardly tapering funnel segment so as to allow the at least one object to be weighed to rapidly assume a position of rest. 9. The weighing station of claim 8, wherein an angle of aperture of the funnel segment substantially corresponds to the angle that defines one of the segmented areas about the axis of the conveyor element. 10. The weighing station of claim 1, wherein the conveyor element comprises a wheel having a number of boundary components which extend with respect to the axis of the conveyor element such that adjacent boundary components define a respective segmented area of the conveyor element, and wherein to transport the weighed object further, a respective boundary component laterally acts upon said object to push it off the support element as the wheel is rotating. 11. The weighing station of claim 1, wherein the conveyor element and its driving mechanism as well as the support element are borne by the load receiver of a load cell. 12. The weighing station of claim 1, wherein the support element is as adapted to be able to receive and discharge, regardless of the format, objects of different shapes. 13. The weighing station of claim 1, wherein the conveyor element is adapted for continuous or quasi-continuous rotation into a first direction, with the rotation being interruptible or reversible in specifiable cases. 14. The weighing station of claim 1, wherein the conveyor element is adapted to be driven by means of a stepping motor or a magnetic drive. 15. The weighing station of claim 1, wherein at least one sensor is provided for detecting the angle of rotation (α). 16. The weighing station of claim 15 in which the sensor is a contactless sensor. 17. A system of weighing stations for weighing and sorting objects to be weighed, the system comprising: two or more weighing stations, each weighing station comprising:a) a load receiver for picking up a gravity force to be applied in a load transfer direction;b) a support element borne by the load receiver for temporarily holding and weighing at least one object;c) a conveyor element which, during or after the weighing step, rotates about an axis for transporting the at least one object from a weighing position on the support element;d) said conveyor element comprising a number of segmented areas that are disposed about the axis of the conveyor element in such a manner that during the weighing step, the at least one object to be weighed comes to lie in a respective segmented area;e) said conveyor element adapted to be rotated, in a conveying step, by a specifiable angle of rotation about its axis to transport the at least one object from the weighing position; andf) wherein the axis of the conveyor element forms an angle (β)<90° with the load transfer direction and wherein the conveyor element is further adapted to, as the at least one object is transported from the weighing position by the conveyor element, transport said object into a selected one of at least two different discharge areas adjacent to the conveyor element; andwherein at least one selected pair of neighboring weighing stations use a common discharge area for discharge of the same type.
