Abstract:
1. A method for operating an electromagnetic transfer system ( 10 ) used to convey items ( 1 : 1 a ) to a downstream conveyor device ( 15 ), the system comprising a carrier path ( 20 ), on which there is at least one movable transport element ( 22 ) for an item ( 1 ; 1 a ) that is moved along on a transport surface ( 24 ) by said transport element ( 22 ), said transport element ( 22 ) having at least one permanent magnet element ( 32 ) that is arranged to be functionally connected to individually-energizable inductor coils ( 31 ) which are arranged along the carrier path ( 20 ), wherein position-detecting means ( 35 ) for ascertaining a position of the transport element ( 22 ) are provided on said carrier path ( 20 ) and, in a delivery region ( 37 ), the item ( 1 ; 1 a ) is delivered from the transport surface ( 24 ) to the downstream conveyor device ( 15 ), said conveyor device having a separate drive ( 38 ), the method comprising, in order to reduce spacing (A, A1, A2) between individual items ( 1 ; 1 a ) on the downstream conveyor device ( 15 ), at least one of the following steps: (A) a conveyor speed (v4) of said conveyor device ( 15 ) is reduced intermittently at a point of delivery from the transport surface ( 24 ) to the conveyor device ( 15 ) in relation to a speed (v2) of the transport element ( 22 ); and (B) the speed (v2) of the transport element ( 22 ) is increased at the point of delivery in relation to the conveyor speed (v4) of the conveyor device ( 15 ).
