Abstract
Device for weighing flat objects in motion comprising a conveyor (12) with drive rollers (22A, 22B) for conveying the flat objects along a transport path (14), a weighing plate (16) facing said transport path and comprising a set of free rollers (160) for receiving the flat objects, and a weighing sensor (18) attached to the weighing plate for measuring the weight of the flat objects during their passage between the conveyor and the weighing plate, wherein the weighing sensor is arranged above the transport path and the conveyor is adapted to move vertically in order to press the flat objects in motion against the weighing plate.

Device for weighing flat objects in motion comprising a conveyor (12) comprising drive rollers (22A, 22B) having a first horizontal axis for conveying along a horizontal transport path (14) the flat objects laying on the conveyor by one of their flat surface, a weighing plate (16) above the conveyor and facing said horizontal transport path and comprising a set of free rollers (160) having a second horizontal axis for receiving the flat surface of the flat objects oriented horizontally, and a weighing sensor (18) attached to the weighing plate for measuring the weight of the flat objects during their passage along the horizontal transport path between the conveyor and the weighing plate, the weighing sensor senses a load applied to at least the weighing sensor,
- wherein the weighing sensor is arranged above the conveyor and the horizontal transport path and the conveyor is configured to move vertically and thereby press, in a vertical direction, the flat objects in motion against the weighing plate such that the sensed load is inversely proportional to the weight of the flat objects.
