Definitions

  • the invention relates to an autonomous, ground-based industrial truck, which comprises a base vehicle with a drive and a load platform on which a load can be positioned, the load platform being provided with a first horizontally conveying load conveyor which is designed to carry the load placed on the load platform to move in the horizontal direction.
  • the invention also relates to a method for loading or unloading a loading unit, in particular a loading area of a truck or a freight train wagon, with an autonomous, ground-based industrial truck.
  • Driverless transport vehicles have recently been used frequently to transport loads in logistical processes, e.g. when loading and unloading trucks.
  • Driverless transport vehicles are ground-based conveyor vehicles with their own drive, which are automatically controlled and guided without contact.
  • the driverless transport vehicles are loaded with the loads or pick up the loads independently.
  • the loads are mostly pallets loaded with goods.
  • the goods can be placed loose or in transport containers, e.g. boxes, on the pallets.
  • a classic pallet truck e.g. a pallet truck or a high-lift truck with a fork made of two forks, has to rotate 180 ° twice per cycle turn and thus turn.
  • the proportion of time it takes to turn the vehicle is already relatively high in manually operated vehicles. In the case of automated vehicles, the turning maneuver can take up most of the time in the process.
  • autonomous undercarriage vehicles with conveyor technology are automated, flat vehicles with a load platform, which e.g. carry a roller conveyor as a load conveyor to move the load on the vehicle.
  • a pallet can be picked up, for example, by a stationary roller conveyor on one side of the vehicle and set down again on another stationary roller conveyor from the opposite side of the vehicle. Since the load platform is at a fixed height on the vehicle, the load can only be set down at staging positions that are at the same height as the load platform.
  • the disadvantage here is that the pallet that has been picked up cannot be set down on the floor (e.g. in a truck).
  • self-propelled forks with driven wheels have also been proposed.
  • Such self-propelled forks can drive under a pallet standing on a floor, lift it and transport it.
  • the disadvantage here is that the self-propelled fork tines must, in principle, be lower than the pockets of a pallet into which the self-propelled fork tines move.
  • the driven wheels of the self-propelled forks can only be very small.
  • such self-propelled forks are not able to drive over the ledges of a typical loading ramp.
  • the field of vision of the sensors attached to the self-propelled forks is very limited, which means that free navigation without markings on the ground is hardly possible.

  • the fork carrier device consists of a wider roller conveyor and a narrower roller conveyor, which is fixedly arranged at the front end of the wider roller conveyor.

  • the U.S. 2,466,055 A discloses an industrial truck in which the load-carrying means has roller tracks arranged next to one another and conveyor belts running on the roller tracks, as a result of which a load can be picked up and deposited by means of the conveyor belts.
  • the present invention is based on the object of designing an industrial truck of the type mentioned and a method for loading a loading unit with the industrial truck so that, on the one hand, loading units with uneven access can also be loaded and, on the other hand, the load can also be placed on the ground and / or off Soil can be absorbed.
  • this object is achieved according to the invention in that at least one height-adjustable load handling device with a further horizontally conveying load handling device is attached to the base vehicle, the load handling device being designed in such a way that when the load handling device is lowered, the load picked up by the load handling device touches the ground, and in the raised state of the load handling device, the load handling device of the load handling device forms a common conveying level with the load handling device of the basic vehicle, on which the load can be moved horizontally to and fro between the load platform of the basic vehicle and the load handling device, the basic vehicle having an electronic control device that has a enables fully automatic control of the drive system as well as the load handling device and the load handling device.
  • the height-adjustable load handling device with horizontally conveying load conveyor which is provided in addition to the basic vehicle, means that the basic vehicle itself can build higher.
  • the height of the basic vehicle is no longer limited by the fact that it must be able to drive under the load on the ground.
  • Picking up and / or setting down the load is now carried out by the height-adjustable load handling device.
  • the horizontally conveying load conveyor shifts the load from the base vehicle to the load handling device or from the load handling device to the basic vehicle. Due to the possible greater height of the basic vehicle, larger wheels, in particular larger drive wheels, can be installed on the basic vehicle, which allow driving on uneven entrances to the loading unit, for example loading ramps with steps or lane edges. Despite the height of the base vehicle and thus the load platform arranged on it, the load can be picked up from the ground and / or set down on the ground due to the presence of the load-bearing means.
