at a bearing 29 which is fastened by screws 30 to the rails 32 and 33 of the carrier 31 by adjusting the bolt 28 and thus the control member 27 the halves 22 and 23 may be pivoted sideways thereby opening and closing the transport container 21 for the actuation of the bolt 28 a thrust bolt 4 is provided at the loading station 2 which is controlled via a linkage 5 with respect to the amount of piece goods that is conveyed towards the transport containers a thrust bolt 6 provided for the same purpose at the unloading station 3 is actuated by a servo device 7 which is controllable with respect to the working cycle of the packing unit that is interconnected with this transport device 1 the transport containers 21 that have been loaded at the loading station 2 engage the transport wheel 12 as soon as the respective adjustable abutment 51 is released the transport containers 21 are then conveyed to the unloading station 3 the engagement is achieved such that due the force of the spring 42 the clamping part 35 is forced against the contact surface 17 of the transport wheel 12 so that a frictional connection is achieved in the case that a transport container 21 is already present at the unloading station 3 the drive connection is suspended and the transport container 21 is not conveyed any further since the protruding projection.
