Abstract

An inspection device in a radiation protection housing comprises an electromagnetic radiation-based inspection device, especially an X-ray device and a weighing device. The inspection device an endless conveyor belt for transporting products in a transport direction from an entry region to an inspection region, from there to a region for weighing, and from there to an exit region of the inspection device. An upper run of the endless conveyor belt in its path from the region for weighing to the exit region, traverses a height difference in in a height direction by means of an inclined region. The conveyor belt circulates around at least part of the inclined region and the weighing device, looking in the transport direction, is disposed immediately in front of the inclined region in the inspection device.

First claim

The invention claimed is:

1. An inspection device including:
(a) a radiation protection housing;
(b) an electromagnetic radiation-based inspection device;
(c) a weighing device;
(d) a conveyor operable to transport products in a transport direction along a product path through the inspection device from an entry region, then to an electromagnetic radiation inspection region of the electromagnetic radiation-based inspection device, then to a weighing region of the weighing device, and then to an exit region;
(e) wherein the product path from the weighing region to the exit region includes an inclined region that traverses an exit height difference in a height direction which extends orthogonal to both the transport direction and a width direction of the inspection device;
(f) wherein the conveyor includes a conveyor belt that circulates along the product path through both the electromagnetic radiation inspection region of the electromagnetic radiation-based inspection device and the weighing region of the weighing device and also circulates around at least part of the inclined region; and
(g) wherein the weighing region is disposed immediately in front of the inclined region in the transport direction:
wherein the weighing device comprises a weighing module that is insertable as a unit into the inspection device and removable as a unit from the inspection device, and wherein at least part of the inclined region is defined by a weighing module outlet ramp component fixed in place on the weighing module.

2. The inspection device of claim 1 wherein at least some of the inclined region is located within the radiation protection housing.

3. The inspection device of claim 1 wherein the weighing module includes a weighing platform for receiving a product to be weighed and wherein the weighing module outlet ramp component is isolated from the weighing platform.

4. The inspection device of claim 1 wherein at least part of the inclined region is defined by a component of a sorting device.

5. The inspection device of claim 1 wherein the weighing device includes a weighing cell and a weighing platform.

6. The inspection device of claim 5 wherein the weighing device further includes a belt guide unit aligned with the weighing platform in a fixed position on the weighing device at an upstream location relative to the weighing platform.

7. The inspection device of claim 1 wherein the product path from the entry region to the electromagnetic radiation inspection region represents an entry ramp that traverses an entry height difference in the height direction.

8. The inspection device of claim 7 wherein the entry height difference is greater than a product maximum height in the height direction.

9. The inspection device of claim 8 wherein the exit height difference is greater than the product maximum height in the height direction.

10. The inspection device of claim 1 wherein the exit height difference is greater than a product maximum height in the height direction.

11. The inspection device of claim 1 wherein the entry region and exit region are substantially aligned in the height direction.
