Abstract

A rejector device for rejecting discrete products from a product stream includes a transporting means, a rejecting means, and at least two collection containers. The rejecting means can reject the products of the product stream either into one collection container or into the other. In the process, the products are rejected either towards one side of the transporting means or towards the other. The arrangement of the collection containers one above the other on one side of the transporting means makes it possible for the operator to remove products from both collection containers from one side of the rejector device.

First claim

The invention claimed is:

1. A rejector device for rejecting discrete products from a product stream, the rejector device including:
(a) transporting means for conveying products in a conveying direction along a conveying path, the transporting means having a first side along the conveying path and a second side along the conveying path, the first side and second side being spaced apart in a transverse direction which extends transverse to the conveying direction so that the first side and second side lie opposite to each other across the conveying path;
(b) rejecting means for rejecting selected products from the products conveyed along the conveying path such that each selected product is moved from the conveying path towards a one of the first side and the second side of the transporting means chosen for that selected product;
(c) a first collection container for receiving a respective selected product moved from the conveying path by the rejecting means toward the first side of the transporting means; and
(d) a second collection container for receiving a respective selected product moved from the conveying path by the rejecting means toward the second side of the transporting means, wherein the first and second collection containers are arranged at least partially one above the other in a Z direction which extends perpendicular to both the conveying direction and the transverse direction, and wherein the first collection container and the second collection container are each accessible from one of the first side and the second side of the transporting means.

2. The rejector device of claim 1 wherein the first collection container and the second collection container are each located at least partially on the one of the first side and second side of the transporting means from which they are accessible.

3. The rejector device of claim 1 wherein a respective one of the selected products moves along a first path when rejected from the conveying path towards the first side of the transporting means and moves along a second path when rejected from the conveying path towards the second side of the transporting means, wherein the first path leads into the first collection container and the second path leads into the second collection container.

4. The rejector device of claim 3 wherein the first collection container is arranged adjacent to the first side of the transporting means.

5. The rejector device according to claim 3 wherein the second path leads under the transporting means into the second collection container.

6. The rejector device of claim 3 wherein the second path is formed at least in part along a chute.

7. The rejector device of claim 6 wherein the chute along at least a portion of a length thereof comprises a closed channel.

8. The rejector device of claim 1 wherein the second collection container extends in the transverse direction under the transporting means from the first side of the transporting means to the second side of the transporting means.

9. The rejector device of claim 1 wherein the first collection container includes a first product removal opening and the second collection container includes a second product removal opening, the first product removal opening and the second product removal opening each being in an accessible location with respect to the one of the first side and the second side of the transporting means from which the first collection container and second collection container are accessible.

10. An inspection system including:
(a) inspection means for inspecting at least one characteristic of each product in a stream of products, the inspection means including at least one of a weighing machine, an electromagnetic radiation scanning device, and an optical code recognition device; and
(b) a rejection device including,
(i) transporting means for conveying the stream of products in a conveying direction along a conveying path from the inspection means, the transporting means having a first side along the conveying path and a second side along the conveying path, the first side and second side being spaced apart in a transverse direction which extends transverse to the conveying direction so that the first side and second side lie opposite to each other across the conveying path;
(ii) rejecting means for rejecting selected products from the stream of products conveyed along the conveying path such that each selected product is moved from the conveying path towards one of the first side and the second side of the transporting means chosen for that selected product;
(iii) a first collection container for receiving a respective selected product moved from the conveying path by the rejecting means toward the first side of the transporting means; and
(iv) a second collection container for receiving a respective selected product moved from the conveying path by the rejecting means toward the second side of the transporting means, wherein the first and second collection containers are arranged at least partially one above the other in a Z direction which extends perpendicular to both the conveying direction and the transverse direction, and wherein the first collection container and the second collection container are each accessible from one of the first side and the second side of the transporting means.

11. The inspection system of claim 10 wherein the first collection container and the second collection container are each located at least partially on the one of the first side and second side of the transporting means from which they are accessible.

12. The inspection system of claim 10 wherein a respective one of the selected products moves along a first path when rejected from the conveying path towards the first side of the transporting means and moves along a second path when rejected from the conveying path towards the second side of the transporting means, wherein the first path leads into the first collection container and the second path leads into the second collection container.

13. The inspection system of claim 12 wherein the first collection container is arranged adjacent to the first side of the transporting means.

14. The inspection system according to claim 12 wherein the second path leads under the transporting means into the second collection container.

15. The inspection system of claim 12 wherein the second path is formed at least in part along a chute.

16. The inspection system of claim 15 wherein the chute along at least a portion of a length thereof comprises a closed channel.

17. The inspection system of claim 10 wherein the second collection container extends in the transverse direction under the transporting means from the first side of the transporting means to the second side of the transporting means.

18. The inspection system of claim 10 wherein the first collection container includes a first product removal opening and the second collection container includes a second product removal opening, the first product removal opening and the second product removal opening each being in an accessible location with respect to the one of the first side and the second side of the transporting means from which the first collection container and second collection container are accessible.
