Abstract

A device and a method for processing parent parts and for sorting waste parts thereby separated. For this purpose, an optical detection unit is provided, which is configured to detect at least one geometric feature G of each waste part and to generate a control signal S corresponding to the at least one detected geometric feature G. The control signal S is transmitted to a sorting unit. The fed waste part is sorted depending on the received control signal S. It is thus possible to assign the separated waste parts to a specific parent part. This in turn enables an assignment and determination of the material of which the waste part consists, which specifically corresponds to the material of which the parent part consists. This enables the waste parts to be separated into different categories.

First claim

What is claimed is:

1. A device ( 10 ) for processing metal parent parts ( 11 ) and for sorting metal waste parts ( 12 ), comprising:
at least one press ( 13 ) or at least one press station ( 14 ) having an upper tool ( 13 ) and a lower tool ( 14 ) for processing the parent part ( 11 ),
at least one separation unit ( 22 ), which is configured to separate at least one portion ( 24 ) of the parent part ( 11 ) to be separated, wherein each separated portion ( 24 ) forms a waste part ( 12 ),
a press ( 13 ) or press station ( 14 ) of the at least one press ( 13 ) or press station ( 14 ) forms the separation unit ( 22 ) and comprises a separation tool part ( 23 ) for separating the at least one portion ( 24 ) to be separated, and/or in that a press ( 13 ) or press stage ( 14 ) of the at least one press ( 13 ) or press stage ( 14 ) comprises a shaping tool part for shaping the parent part ( 11 ),
an optical detection unit ( 38 ), which is configured to detect at least one geometric feature (G) of each waste part ( 12 ), and to generate a control signal (S) corresponding to the at least one detected geometric feature (G), the at least one geometric feature (G) is the outer contour of the waste part ( 12 ) and/or the contour of a portion or region of the waste part ( 12 ), and,
a sorting unit ( 33 ), which is configured to remove and to deposit and/or to convey further onwards the at least one waste part ( 12 ) fed to the sorting unit ( 33 ), depending on the control signal (S).

2. The device according to claim 1 , characterized in that a marking unit ( 43 ) is provided and is configured to apply to the at least one portion ( 24 ) of the parent part ( 11 ) a marking (M 1 , M 2 , M 3 ) which characterizes the material of the parent part ( 11 ) and which constitutes at least one optically detectable geometric feature (G).

3. The device according to claim 2 , characterized in that the marking (M 1 , M 2 , M 3 ) to be applied in a material-dependent manner is predefined to the marking unit ( 43 ) depending on the material of the parent part ( 11 ).

4. The device according to claim 2 , characterized in that the marking unit ( 43 ) is configured to apply a marking (M 1 , M 2 , M 3 ) that protrudes and/or is recessed relative to the bordering surface of the portion ( 24 ) to be separated.

5. The device according to claim 2 , characterized in that the marking unit ( 43 ) comprises at least one laser ( 46 ) for engraving the marking (M 1 , M 2 , M 3 ) into the portion ( 24 ) of the parent part ( 11 ) to be separated.

6. The device according to claim 1 , characterized in that a marking unit ( 43 ) is provided and is configured to apply a marking (M 1 , M 2 , M 3 ) characterizing the material of the parent part ( 11 ) to the at least one portion ( 24 ) of the parent part ( 11 ), and in that the marking unit ( 43 ) comprises at least one marking plunger ( 44 ), which is arranged on the upper tool ( 15 ) and/or on the lower tool ( 16 ) of a press ( 13 ) or press station ( 14 ) of the at least one press ( 13 ) or press station ( 14 ).

7. The device according to claim 2 , characterized in that the marking unit ( 43 ) is configured to introduce the marking (M 1 , M 2 , M 3 ) in such a way that it is optically detectable on two opposite sides of the waste part ( 12 ).

8. The device according to claim 1 , characterized in that the sorting unit ( 33 ) comprises at least one feed channel ( 34 ) and at least two outlet channels ( 35 ), wherein the sorting unit ( 33 ) is configured to convey the at least one waste part ( 12 ) arriving at the feed channel ( 34 ) further on to one of the provided outlet channels ( 35 ) depending on the control signal (S).

9. The device according to claim 1 , characterized in that a conveying unit ( 28 ) for carrying away the at least one waste part ( 12 ) is provided, and in that the optical detection unit ( 38 ) is arranged adjacently to the conveying unit ( 28 ) and is arranged before the sorting unit ( 33 ) as considered in the conveying direction of the conveyed waste parts ( 12 ), or is arranged at a feed channel ( 34 ) of the sorting unit ( 33 ).

10. The device according to claim 1 , characterized in that the optical detection unit ( 38 ) comprises at least one camera ( 39 ).

11. The device according to claim 10 , characterized in that the at least one camera ( 39 ) is embodied as a monochrome camera.

12. The device according to claim 1 , characterized in that the sorting unit ( 33 ) comprises at least one sorting robot ( 36 ).

13. A method for processing metal parent parts ( 11 ) and for sorting metal waste parts ( 12 ) with a device ( 10 ) for processing metal parents parts ( 11 ) and for sorting metal waste parts ( 12 ), said device ( 10 ) comprising:
at least one press ( 13 ) or at least one press station ( 14 ) having an upper tool ( 13 ) and a lower tool ( 14 ) for processing the parent part ( 11 ),
at least one separation unit ( 22 ), which is configured to separate at least one portion ( 24 ) of the parent part ( 11 ) to be separated, wherein each separated portion ( 24 ) forms a waste part ( 12 ),
a press ( 13 ) or press station ( 14 ) of the at least one press ( 13 ) or press station ( 14 ) forms the separation unit ( 22 ) and comprises a separation tool part ( 23 ) for separating the at least one portion ( 24 ) to be separated, and/or in that a press ( 13 ) or press stage ( 14 ) of the at least one press ( 13 ) or press stage ( 14 ) comprises a shaping tool part for shaping the parent part ( 11 ),
