Abstract

A transport device and a method for producing a coin with use of the transport device. The transport device is used to transport blanks to a minting station. A drivable first transport part having a plurality of first transport pockets is provided. A first clearance exists between the outer contour of the blank and the inner contour of the first transport pocket. The transport device has a second transport part having a plurality of second transport pockets. A second clearance is provided between the outer contour of the blank and the inner contour of the second transport pocket. The second clearance is larger than the first clearance. The blanks are transferred at a transfer location from a particular first transport pocket into a second transport pocket. The blanks are transported in the second transport pocket to the minting station, and a coin is minted there from the blank.

First claim

a transport device ( 15 ) comprising:
a drivable first transport part ( 19 ), including a plurality of first transport packets ( 20 ) each configured to receive a single multi-part blank of the plurality of multi-part blanks ( 16 ) and each of the first transport packets ( 20 ) configured to provide a first clearance (S 1 ) between an outer contour ( 51 ) of the received single multi-part blank ( 16 ) and an inner contour ( 50 ) of the first transport pocket ( 20 ),
a drivable second transport part ( 26 ), including a plurality of second transport pockets ( 27 ) each configured to receive the received single multi-part blank ( 16 ) of the first transport pocket ( 20 ), and configured to provide a second clearance (S 2 ) between the outer contour ( 51 ) of the received single multi-part blank ( 16 ) and an inner contour ( 52 ) of the second transport pocket ( 27 ), wherein the first clearance (S 1 ) is smaller than the second clearance (S 2 ),
the transport device ( 15 ) having a transfer location ( 34 ), at which the received single multi-part blank ( 16 ) is transferred from the drivable first transport part ( 19 ) to the drivable second transport part ( 26 ),
the drivable second transport part ( 26 ) further including a minting station ( 17 ) configured to mint the multi-part coin from the received single multi-part blank ( 16 ), the drivable second transport part ( 26 ) configured to transport the received single multi-part blank ( 16 ) from the transfer location ( 34 ) to the minting station ( 17 ) to be minted and the drivable second transport part ( 26 ) configured to transport the minted multi-part coin from the minting station ( 17 ) to a removal location ( 40 ).

2. The transport device system according to claim 1 , characterised in that the plurality of constituents of each of the multi-part blanks ( 16 ) comprises an inner constituent ( 43 ) and an outer constituent ( 46 ).

3. The transport device according to claim 2 , characterised in that at least one preparation station ( 44 , 47 ) is arranged adjacently to the first transport part ( 19 ) and is configured to prepare each of the received single multi-part blanks ( 16 ) for a subsequent minting operation at the minting station ( 17 ).

4. The transport device system according to claim 3 , characterised in that the at least one preparation station includes a joining station ( 47 ), at which at least the inner constituent ( 43 ) and the outer constituent ( 46 ) of the plurality of constituents are joined together to form each of the received single multi-part blank ( 16 ).

5. The transport device according to claim 3 , characterised in that the outer constituent ( 46 ) of each of the received single multi-part blank ( 16 ) is formed from a pre-constituent blank disc ( 42 ), the at least one preparation station includes a hole-forming station ( 44 ) and/or a forming station, at which a hole ( 45 ) is formed in the pre-constituent blank disc ( 42 ) to form the outer constituent ( 46 ) comprising a ring.

6. The transport device system according to claim 1 , characterised in that a control device ( 30 ) is provided, which is configured to control a first drive ( 22 ) for the drivable first transport part ( 19 ) and a second drive ( 29 ) for the drivable second transport part ( 26 ).

7. The transport device system according to claim 1 , characterised in that the drivable first transport part ( 19 ) is a first revolving plate ( 21 ) and/or the drivable second transport part ( 26 ) is a second revolving plate ( 28 ).

8. The transport device system according to claim 7 , characterised in that the first revolving plate ( 21 ) has a larger diameter than the second revolving plate ( 28 ).

9. The transport device system according to claim 1 , characterised in that the number of first transport pockets ( 20 ) at the drivable first transport part ( 19 ) is greater than the number of the second transport pockets ( 27 ) at the drivable second transport part ( 26 ).

10. A method for producing the minted multi-part coin with use of the transport device system according to claim 1 , said method comprising the following steps:
transporting the received single multi-part blank ( 16 ) in one of the plurality of first transport pockets ( 20 ) of the drivable first transport part ( 19 ) to the transfer location ( 34 ), while providing the first clearance (S 1 ) between the outer contour ( 51 ) of the received single multi-part blank ( 16 ) and the inner contour ( 50 ) of the one first transport pocket ( 20 ),
