Abstract

The invention describes a transfer conveying apparatus (1) having small conveying rollers (14) which form a conveying plane (13) for an item of transported goods (3) for a main conveying direction and at least one auxiliary conveying direction with a pivoting apparatus for pivoting the small conveying rollers (14) about pivot axes which extend perpendicularly with respect to the conveying plane (13) and with a drive apparatus for the small conveying rollers (14). A load-bearing frame of the transfer conveying apparatus (1) having at least one row (11) of the small conveying rollers (14) arranged transversely with respect to the main conveying direction and having pivoting transfer and drive transfer for the row (11) of the small conveying rollers (14) forms a conveying module which is connected detachably to a base module having at least one pivoting drive arrangement and at least one small-roller drive arrangement.
