A device for installation at a picking and/or packaging workstation for packing a packing order of several, in particular unequal packages onto a load carrier, comprising: - a placement area for the load carrier; - a workstation for an operator; - a computer with software for calculating an optimized packing pattern and a corresponding packing sequence of work steps; and - a display for displaying a workplace dialog, wherein the computer is designed to display instructions for a next work step of the packing sequence for placing the respective next package according to the optimized packing pattern on the display, further comprising at least one 3D sensor that is directed at the placement area for the load carrier, wherein the computer is designed to: - capture the data of the 3D sensor and determine an actual packing pattern on the load carrier from it; - compare the actual packing pattern with a target packing pattern that was to be expected after scheduled execution of the last work step; - perform a new optimization of the packing pattern in real time when there are deviations between the actual packing pattern and the target packing pattern, whereby the actual packing pattern is used as a boundary condition and the packing of the remaining packages in a remaining residual volume is optimized to obtain a new optimized packing pattern and a corresponding remaining packing sequence for the remaining packages; and - display instructions for a next work step of the remaining packing sequence for placing the respective next package according to the newly optimized packing pattern on the display, characterized in that the computer is designed to prompt the operator via the workplace dialog to confirm the deviation after detecting a deviation between the actual packing pattern and the target packing pattern, to calculate a newly optimized packing pattern only after confirmation has been given, and otherwise to prompt the operator via the workplace dialog to reposition the package according to the original packing pattern. - a placement area for the load carrier; - a workstation for an operator; - a computer with software for calculating an optimized packing pattern and a corresponding packing sequence of work steps; and - a display for displaying a workplace dialog, wherein the computer is designed to display instructions for a next work step of the packing sequence for placing the respective next package according to the optimized packing pattern on the display, further comprising at least one 3D sensor that is directed at the placement area for the load carrier, wherein the computer is designed to: - capture the data of the 3D sensor and determine an actual packing pattern on the load carrier from it; - compare the actual packing pattern with a target packing pattern that was to be expected after scheduled execution of the last work step; - perform a new optimization of the packing pattern in real time when there are deviations between the actual packing pattern and the target packing pattern, whereby the actual packing pattern is used as a boundary condition and the packing of the remaining packages in a remaining residual volume is optimized to obtain a new optimized packing pattern and a corresponding remaining packing sequence for the remaining packages; and - display instructions for a next work step of the remaining packing sequence for placing the respective next package according to the newly optimized packing pattern on the display, - capture the data of the 3D sensor and determine an actual packing pattern on the load carrier from it; - compare the actual packing pattern with a target packing pattern that was to be expected after scheduled execution of the last work step; - perform a new optimization of the packing pattern in real time when there are deviations between the actual packing pattern and the target packing pattern, whereby the actual packing pattern is used as a boundary condition and the packing of the remaining packages in a remaining residual volume is optimized to obtain a new optimized packing pattern and a corresponding remaining packing sequence for the remaining packages; and - display instructions for a next work step of the remaining packing sequence for placing the respective next package according to the newly optimized packing pattern on the display, characterized in that the computer is designed to prompt the operator via the workplace dialog to confirm the deviation after detecting a deviation between the actual packing pattern and the target packing pattern, to calculate a newly optimized packing pattern only after confirmation has been given, and otherwise to prompt the operator via the workplace dialog to reposition the package according to the original packing pattern.
