Definitions
- the invention relates to a material handling vehicle, in particular a forklift truck, with at least one lifting mast and a load carrying means carrier arranged vertically to the mast and an antenna arranged in the area of the lifting mast for wireless communication with an identification system, in particular with RFID transponders.
- the antenna device is used in particular for Pulklesen of metallic containers, lattice boxes, barrels, etc.
- a forklift RFI D system which has at least one first RFID antenna positioned on a fixed portion of a mast of the forklift. At least one further antenna is arranged on the movable section of the load receiving means.
- the disadvantage of this is that the reception conditions are not optimal if the RFID tags are mounted at very different positions.
- the invention relates to an industrial vehicle with at least one mast and a vertically arranged thereon movable to the mast
- the antenna extends this maximum over the entire Hubmast endeavor and Hubmastlessness.
- the antenna comprises any number of radiation elements which are distributed over the entire Hubmastbus. This will ensure an optimal placement of the antenna without
- the radiowaves emanating from the radiating elements of the antenna can reach the pulp directly without disturbing obstacles by the arrangement according to the invention.
- the radiation elements are linearly polarized.
- Radiation elements continuously successively activated by an electronic circuit or control.
- the radiation elements are activated individually at a time interval by an electronic circuit or control.
- Fig. 1 is a side view of a schematically simplified representation of a
- FIG. 2 is a front view of the vehicle of FIG. 1,
- Fig. 3 is a simplified illustration of an antenna having a plurality of
- a material handling vehicle in particular a forklift 1 with a load in the form of a plurality of stacked lattice boxes 10 are shown.
- the layers of lattice boxes 10 are spaced from each other by the container foot pieces 10a.
- the lattice boxes are equipped with RFID transponders for individual recognition in the pulping process.
- the forklift 1 comprises two lifting masts 1.1, 1.2 and arranged thereon a load-carrying means carrier 1.3 which is movable vertically to the masts and has two load forks 1.4, 1.5.
- antennas 20 are arranged over the entire Hubmast love. These can be arranged on the surface of the lifting masts 1.1, 1.2 or integrated into the surface.
- the antennas 20 may have any number of radiation elements 20.1 n .
- Drawings can be optimally read if the antenna 20 is positioned so that the radio waves starting from the beam element 20.1 n can reach and penetrate the pulp as close as possible and without disturbing obstacles.
- the UHF frequency range, HF or LF is used.
- the antenna width is preferably chosen narrow, ie about 200 mm analog hub width so there is no obstruction of the driver.
- the antenna length can be configured analogously to the lifting mast height.
- the antennas are very flat (about 25 mm) so that no problems arise for the lifting unit in which the forks are anchored.
- beam elements 20.1 n can be integrated over the entire lifting mast height or length.
- Linearly polarized beam elements are preferably used because the beam propagation through the container foot gaps is better.
- Radiation elements 20.1 n are successively activated by an electronic circuit / control separately or by the associated reader itself only one at a time interval, for example, a quarter of a second.
- an active jet element is always located precisely in the optimum position for the container foot gap as a result of the additional stroke movement.
- the antenna emitters can be integrated directly into the mast 1.1, 1.2 for new truck models. Whether multiple jet elements or a jet element which is moved mechanically, electrically or pneumatically on or in the mast is no matter.
