Tray for transporting a load in an order-picking system, unloading device and loading device

A computer-implemented method for controlling (60) a position changing device (35) for changing a pose of a load (4) and for the situational positioning of the load (4) by a control device (50), comprising the following steps:

• acquiring a loading order for loading a tray (1) with a load (4) by a computer system (51),
• acquiring load dimensions by a load acquisition system (52) and transferring the acquired load dimensions from the load acquisition system (52) to the computer system (51),
• acquiring a loading width (d1, d2) of the tray (1) by a tray acquisition system (53) and transferring the acquired loading width (d1, d2) from the tray acquisition system (53) to the computer system (51),
• comparing the load dimensions with the loading width (d1, d2) by the computer system (51),
• determining, by the computer system (51), a loading pose for the load (4) which is to be placed on the tray (1), wherein the loading pose is determined using the load dimensions in such a way that a rotation of the load (4) on the tray (1) is restricted by the loading width (d1, d2),
• generating, by the computer system (51), a control specification (59) for controlling (60) the position changing device (35) to bring the load (4) into the loading pose, and
• transferring the control specification (59) from the computer system (51) to the control device (50) and control of the position changing device (35) according to the control specification (59) by the control device (50).
