A device for handling piece goods, which piece goods are moved in at least three parallel rows, the device comprising - at least one transport device, by means of which transport device the moved piece goods can be transported in at least three rows in a transport direction to seizing ranges of the at least two manipulators, - wherein the device comprises at least two manipulators for piece goods, which manipulators can be controlled and moved independently of one another, - wherein at least one horizontal conveying device is associated with the seizing ranges of the at least two manipulators, which horizontal conveying device respectively adjoins the transport devices in an aligned manner, and which horizontal conveying device transports the piece goods in the transport direction, which piece goods are reaching the seizing ranges and are rotated and/or displaced therein by means of the manipulators, characterized by - at least two movable optical detection devices, which optical detection devices are assigned to the seizing ranges and/or the movement spaces of the at least two manipulators and which optical detection devices are each prepared and equipped for obtaining spatial coordinates and/or positional data and/or contour data of at least one piece good of the at least three rows, which piece goods are being moved in the transport direction, - wherein the at least two optical detection devices are designed to be movable on opposite longitudinal sides of the horizontal conveying device parallel to the transport direction in or against the transport direction, - wherein at least the manipulators and/or further conveying components of the device can be calibrated and/or controlled on the basis of the spatial coordinates and/or positional data and/or contour data. - at least one transport device, by means of which transport device the moved piece goods can be transported in at least three rows in a transport direction to seizing ranges of the at least two manipulators, - wherein the device comprises at least two manipulators for piece goods, which manipulators can be controlled and moved independently of one another, - wherein at least one horizontal conveying device is associated with the seizing ranges of the at least two manipulators, which horizontal conveying device respectively adjoins the transport devices in an aligned manner, and which horizontal conveying device transports the piece goods in the transport direction, which piece goods are reaching the seizing ranges and are rotated and/or displaced therein by means of the manipulators, characterized by - at least two movable optical detection devices, which optical detection devices are assigned to the seizing ranges and/or the movement spaces of the at least two manipulators and which optical detection devices are each prepared and equipped for obtaining spatial coordinates and/or positional data and/or contour data of at least one piece good of the at least three rows, which piece goods are being moved in the transport direction, - wherein the at least two optical detection devices are designed to be movable on opposite longitudinal sides of the horizontal conveying device parallel to the transport direction in or against the transport direction, - wherein at least the manipulators and/or further conveying components of the device can be calibrated and/or controlled on the basis of the spatial coordinates and/or positional data and/or contour data.
