  • the robot is designed, for example, as an articulated robot and the reading device is located on the robot.
  • the robot preferably has a suction gripper or a gripper gripper for receiving piece goods.
  • the invention has the advantage that general cargo can already be sorted during the implementation. This is done by selecting a target position for the respective conversion of an object, wherein the target positions can be variably programmed in the control of the robot.
  • the invention can also use existing identification means of piece goods, without having to be adapted.
  • Fig. 1 shows an embodiment of the invention, in which a plurality of pallets are arranged around a robot 20 around.
  • a first pallet 40 On a first pallet 40 is located the piece goods 10 to be converted, this first removal position being marked with X.
  • the other pallets at positions A, B, C and D represent the different target positions for the sorting of the piece goods.
  • An additional pallet at position E is provided for piece goods for which no target position could be determined.
  • conveyor belts may also be provided at the destination positions, which transport articles deposited thereon.
  • Each of the piece goods 10 is expediently provided with a non-contact detectable identification means 11.
  • a non-contact detectable identification means 11 may be, for example, a barcode or an RFID transponder. If a barcode is used, the piece goods may be stacked on the first pallet 40 such that the barood is always on the same side of the items. Such an orientation would allow a robot 20 to selectively pass the particular item to a bar code scanner with this page. If the items with their barcodes are not aligned to one side, multiple pages of items need to be scanned.
  • an identification means 11 various information can be included, which can be read by a reading means. According to the invention, it is determined from the deposited information to which target position an object is to be converted. For a piece of goods 10 thus no target position can be determined if it has no means of identification 11, because this example has been resolved or can not be read. If a barcode is located on the side of the item at which the item is picked up by the robot with a gripper, there is the possibility that the gripper may obscure the barcode and that it can not be scanned. In both cases, the respective object is converted to the pallet at the storage position E. The items sold there must be sorted. This can be done manually or by an additional robot, for example another
  • the target position of the associated piece goods 10 can be contained directly. If piece goods are always sorted by a robot to the same positions, this position can be stored in the means of identification so that it can be read out directly from the controller of the robot and converted into robot movements. If the destination positions change, however, the data content of the identification means must be adapted.
  • the target position can only be determined indirectly from an identification means 11. If the piece goods are, for example, postal parcels, a destination address can be stored in the identification means. From this, the controller of the robot can determine the target position for sorting by storing an assignment between destination addresses and the target positions in the controller. For example, postal packages with different postal code areas are sorted on different pallets or conveyor belts. The robot controller calls this assignment and determines the target position of the associated piece goods.
  • the identification means contains no destination information, but only an identification of the respective piece goods.
  • the controller of the robot has access to an assignment of
  • Identifications of objects to target positions For example, all objects with a product number in a certain number range are converted to a specific target position.
  • the indirect determination of a target position for example, from a postal destination address or an identification number has the advantage that the required assignment between these data and the destination positions can be changed. If the infrastructure or the further processing process changes for a specific group of unit loads, only the assignment in the controller of the robot has to be changed without the data content of the identification means having to be changed. For an assignment, thus any data can be used by information carriers that already exist for other purposes are, so that existing identification means for the application of the method according to the invention need not be changed.
  • the target position can be determined by the reading device or the controller of the robot. If the reading device is designed to determine the target position, it transmits it to the controller of the robot. If the controller of the robot determines the target position itself, the reading device 30 transmits the information read from the identification means 11 to it.
  • the robot 20 can be designed in the usual way, as is known from the prior art for the transfer of piece goods. Particularly advantageous is an articulated robot has proven that is movable in all axes. If an articulated robot is used, which is only vertically and horizontally movable, this can be arranged on a rotary plate to allow movement to multiple target positions.
