Electromagnetic transfer system
The invention relates to an electromagnetic transfer system ( 100 ) having a preferably closed carrier path ( 20 ), along which a multiplicity of individually activatable induction coils ( 25 ) are arranged, and having conveying elements ( 30, 30 a to 30 e ), which are arranged in a movable manner on the carrier path ( 20 ) and each have a driver element ( 38 ), which serves for conveying in each case at least one article ( 1 ) from a first conveying arrangement ( 11 ), along a conveying route ( 18 ) in the region of the transfer system ( 100 ), into a second conveying arrangement ( 12 ) arranged downstream, wherein the driver elements ( 38 ) are in abutting contact with the at least one article ( 1 ) at least along the conveying route ( 18 ), and wherein the conveying element ( 30, 30 a to 30 e ) has, as drive element, at least one permanent-magnet element ( 31 ) arranged in operative connection with the induction coils ( 25 ). According to the invention, it is provided that the driver element ( 38 ) is arranged on the conveying element ( 30, 30 a to 30 e ) such that it can be moved, in particular pivoted, in order to be brought into abutting contact with, and removed from abutting contact with, the at least one article ( 1 ), wherein the driver element ( 38 ) is moved by at least one actuating element ( 43, 44 ) arranged at a fixed location on the carrier path ( 20 ).
1. An electromagnetic transfer system ( 100 ) having a carrier path ( 20 ), along which a multiplicity of individually activatable induction coils ( 25 ) are arranged, and having conveying elements ( 30 , 30 a to 30 e ), which are arranged such that the conveying elements can move on the carrier path ( 20 ) and each have a driver element ( 38 ), which is used to convey in each case at least one article ( 1 ) from a first conveying device ( 11 ) along a conveying section ( 18 ) in a region of the transfer system ( 100 ) into a second conveying device ( 12 ) arranged downstream, the driver elements ( 38 ) being in touching contact with the at least one article ( 1 ), at least along the conveying section ( 18 ), and the conveying element ( 30 , 30 a to 30 e ) having, as drive element, at least one permanent magnet element ( 31 ) arranged in operative connection with the induction coils ( 25 ),
wherein the driver element ( 38 ) is supported for pivoting movement on a carrier element ( 33 ) of the conveying element ( 30 , 30 a to 30 e ) such that the driver element ( 38 ) can be moved to be brought into touching contact and out of touching contact with the at least one article ( 1 ), wherein the movement of the driver element ( 38 ) is carried out by at least one actuating element ( 43 ; 43 a , 44 ; 44 a ) arranged at a fixed location on the carrier path ( 20 ), wherein the conveying element ( 30 , 30 a to 30 e ) further has a locking element ( 41 ) which keeps the driver element ( 38 ) in a conveying position, the locking element ( 41 ) formed as a spring element ( 41 ) arranged on the carrier element ( 33 ), and
wherein the at least one actuating element ( 43 ; 43 a , 44 ; 44 a ) is arranged to cause the driver element ( 38 ) to pivot into and out of touching contact with the at least one article ( 1 ) while the conveying element ( 30 , 30 a to 30 e ) moves along portions of a straight path.
2. The transfer system as claimed in claim 1 , wherein the actuating element ( 43 ; 43 a , 44 ; 44 a ) is formed as a rail and, in order to control the movement of the driver element ( 38 ), forms a guide ( 46 , 47 ) which interacts with a guide pin ( 40 ) arranged at least indirectly on the driver element ( 38 ).
3. The transfer system as claimed in claim 1 , wherein the actuating element ( 43 ; 43 a , 44 ; 44 a ) is arranged only in regions of the carrier path ( 20 ) in which a movement of the driver element ( 38 ) takes place.
4. The transfer system as claimed in claim 1 , wherein the articles ( 1 ) in the region of the transfer system ( 100 ) are conveyed along a rectilinearly formed conveying section ( 18 ), in that the carrier path ( 20 ) has a curved entry region ( 23 ) and a curved exit region ( 24 ) and a rectilinearly formed carrier path section ( 21 ) arranged parallel to the conveying section ( 18 ), and in that the actuating element ( 43 , 44 ) is arranged at least in the region of the entry region ( 23 ) or the exit region ( 24 ).
5. The transfer system as claimed in claim 1 , wherein spacings between the articles ( 1 ) in a region of the conveying section ( 18 ) are changed with respect to spacings (a) of the articles ( 1 ) in a region of the first conveying device ( 11 ) by a retardation or an acceleration of the conveying elements ( 30 , 30 a to 30 e ).
6. The transfer system as claimed in claim 1 , wherein the carrier element ( 33 ) is formed as a format part and is arranged replaceably on the conveying element ( 30 , 30 a to 30 e ).
7. The transfer system as claimed in claim 1 , wherein a third conveying device ( 50 ), in a region of which the driver elements ( 38 ) are arranged in touching contact with the articles ( 1 ) only in some regions, is provided between the two conveying devices ( 11 , 12 ).
8. The transfer system as claimed in claim 7 , wherein the actuating elements ( 43 a , 44 a ) are arranged in a region of the third conveying device ( 50 ).
9. The transfer system as claimed in claim 1 , the transfer system ( 100 ) having a closed carrier path ( 20 ).
