In a packaging line (1) comprising a plurality of robots (7), in order to be able to replace a faulty unit, in particular robot (7), quickly and with minimal, preferably no manpower, in particular during running operation of the packaging line (1), the unit to be changed is automatically decoupled from the power and data feeds and from the purely mechanical connections and is removed from the packaging line (1), preferably transversely to the throughput direction (10′) of the packaging line (1), and the new unit is automatically introduced in the opposite direction, is positioned, and is mechanically fixed, and the energy and data supplies are automatically coupled.

A device assembling system includes a management apparatus, a material apparatus, and an execution apparatus. The management apparatus is communicatively connected to the material apparatus and the execution apparatus, and the material apparatus and the execution apparatus are installed into an overall structure. The management apparatus is configured to obtain a maintenance task of a maintenance device. The maintenance task includes an operation type and an operation object. The management apparatus parses the maintenance task into a first control instruction and a second control instruction. The material apparatus receives the first control instruction, and searches for a to-be-assembled part according to the first control instruction, that is, the material apparatus may determine a position of the to-be-assembled part. The execution apparatus receives the second control instruction, and obtains the to-be-assembled part and assembles the to-be-assembled part to a device according to the second control instruction.
