Provided is a device and method for transporting items. In a transmission device (1) used for transmitting goods (10) on a feeding device (2,3), the goods transmitted in a dense material flow (11) is distributed into at least two channels (13,14) along a transmission direction (TR) by means of at least one separation element (15). The transmission device possesses a detection device (30) in at least one area which distributes goods through at least one separation elements, used for identifying goods (10a) which has a reduced transmission speed relative to a transmission speed (vm) of the transmitted goods in a transmission device (1) and/or goods (10b) which has a substrate (GF) different form a known substrate (GFb) of the goods transmitted in dense material flow and/or states where goods lacks in at least one channel. The transmission device also comprises an operation device (34) used for locating and/or removing the goods identified by the detection device, wherein the operation device can be controlled through the detection device.
