Forklift for the handling of pneumatic tires provided with transponder

1. A forklift for the handling of pneumatic tires each having a central cavity and a transponder, the forklift comprising:

a gripping device configured to engage one or more pneumatic tires;

a reader device comprising an antenna and configured to communicate with transponders of the one or more pneumatic tires;

a displacement unit which supports at least the antenna of the reader device and is configured to move the antenna between a waiting position, wherein the antenna is arranged at a certain distance from the one or more pneumatic tires engaged by the gripping device, and a working position, wherein the antenna is arranged in close proximity to the one or more pneumatic tires engaged by the gripping device and communication is enabled with respective transponders thereof.

2. The forklift of claim 1 , wherein in the working position the antenna of the reader device is arranged within the respective central cavity of at least one of the one or more pneumatic tires.

3. The forklift of claim 1 , wherein the displacement unit is configured for moving the antenna of the reader device along both a horizontal direction and a vertical direction perpendicular to the horizontal direction.

4. The forklift of claim 3 , wherein the displacement unit is configured for moving the antenna of the reader device essentially along the horizontal direction in order to move the reader device nearer to/further away from the one or more pneumatic tires and for moving the antenna of the reader device along the vertical direction in order to slide the reader device along the one or more pneumatic tires.

5. The forklift of claim 1 , wherein the displacement unit comprises an arm, which at a first end is hinged so as to rotate around a horizontal axis of rotation and at a second end opposite the first end it supports the reader device.

6. The forklift of claim 5 , wherein the displacement unit comprises a telescopic member configured to impart a linear movement, is mounted at the second end of the arm, and directly supports the antenna of the reader device.

7. The forklift of claim 1 , wherein the displacement unit is configured for rotating the antenna of the reader device around a longitudinal axis thereof.

8. The forklift of claim 1 , further comprising:

a driver cabin that is closed at a top portion via roof;

wherein the displacement unit is mounted on the roof of the driver cabin.

9. The forklift of claim 1 , further comprising:

a support body whereupon the gripping device is mounted and configured for sliding there along;

wherein the displacement unit is mounted on the top of the support body.

10. The forklift of claim 1 , wherein:

the reader device comprises the antenna and a transmission component; and

only the antenna of the reader device is mounted on the displacement unit in order to be moved by the displacement unit itself between the waiting position and the working position.

11. The forklift of claim 1 , wherein:

the reader device comprises the antenna and a transmission component; and

the entire reader device is mounted on the displacement unit in order to be moved by the displacement unit itself between the waiting position and the working position.

12. The forklift of claim 1 , further comprising:

a camera arranged next to the reader device and configured for framing the one or more pneumatic tires when the reader device is in the working position.

13. The forklift of claim 1 , further comprising:

a computer configured to

receive from an operator of the forklift a number of pneumatic tires loaded onto the gripping device,

receive from the reader device a number of transponders read,

verify that the number of pneumatic tires loaded onto the gripping device is equal to the number of transponders read, and

generate an error signal if the number of pneumatic tires loaded onto the gripping device is different from the number of transponders read.

14. A method of operating a forklift for the handling of pneumatic tires each having a central cavity and a transponder, the method comprising:

engaging one or more pneumatic tires; and

moving an antenna between a first position, wherein the antenna is arranged at a certain distance from the engaged one or more pneumatic tires, and a second position, wherein the antenna is arranged in close proximity to the engaged one or more pneumatic tires and communication is enabled with respective transponders thereof.

15. The method of claim 14 , wherein in the second position the antenna is arranged within the respective central cavity of at least one of the one or more pneumatic tires.

16. The method of claim 14 , comprising moving the antenna in a first direction, along an axis extending through the central cavities of the engaged one or more pneumatic tires, and a second direction perpendicular to the first direction.

17. The method of claim 14 , further comprising rotating the antenna around a longitudinal axis of a displacement unit providing at least a portion of the movement between the first position and the second position.

18. The method of claim 14 , further comprising:

receiving input from an operator of the forklift corresponding to a number of pneumatic tires engaged by a gripping device thereof;

receiving input from a reader device associated with the antenna and corresponding to a number of transponders read;

verifying that the number of pneumatic tires engaged by the gripping device is equal to the number of transponders read; and

generating an error signal if the number of pneumatic tires engaged by the gripping device is different from the number of transponders read.
