Method for servicing a tired-wheel
A tired-wheel having a wheel-rim and a tire thereon is automatically serviced. The method includes loading the tired-wheel onto a motor-driven support mounted for rotation about an axis of rotation, centering the tired-wheel with respect to the axis of rotation, and holding it by use of the motor-driven rotatable support, urging the wheel-rim against the rotatable support by use of an urging device so as to make the tired-wheel rigid in rotation with the rotatable support, disassembling the tire from the wheel-rim by use of a pair of working arms, moving away the urging device and removing the disassembled tire, loading a new tire onto the wheel-rim, repositioning the urging device and urging the wheel-rim against the rotatable support, and mounting the new tire onto the wheel-rim by use of the pair of working arms.
1. A method for automatically servicing a tired-wheel having a wheel-rim and a tire thereon, comprising:
loading said tired-wheel onto a motor-driven support mounted for rotation about an axis of rotation,
centering said tired-wheel with respect to said axis of rotation, and holding said tired-wheel by said motor-driven rotatable support,
urging the wheel-rim against said rotatable support by an urging device so that said tired-wheel rotates with said rotatable support,
disassembling said tire from said wheel-rim by a pair of working arms,
moving away said urging device and removing said disassembled tire,
loading a new tire onto the wheel-rim,
repositioning said urging device and urging said wheel-rim against said rotatable support, and
mounting said new tire onto said wheel-rim by said pair of working arms.
2. A method according to claim 1 , comprising reading information data identifying said tired-wheel.
3. A method according to claim 2 , wherein said reading comprises reading the diameter and the thickness of said tire.
4. A method according to claim 3 , wherein said reading comprises reading a chip built into said tired-wheel.
5. A method according to claim 2 , wherein after said tire has been disassembled from said wheel-rim, information is entered into a chip built into said tire.
6. A method according to claim 5 , wherein after said tire has been disassembled, the method comprising printing a list of any service operations carried out.
7. A method according to claim 1 , wherein said reading comprises locating the position of an inflation valve in the wheel-rim of said tired wheel.
8. A method according to claim 1 , wherein the step of loading said tired-wheel comprises
lying said wheel on a support structure designed to be moved from a rest or wheel-receiving position to a working position above said rotatable support by loading and unloading structure,
clamping said wheel on said support structure by a plurality of clamping elements,
moving said loading-unloading structure away from said support structure,
moving said support structure to a working position, thereby bringing the loaded wheel above said rotatable support, and
causing said wheel controllably to return closer towards said support structure, thereby bringing said wheel onto said rotatable support.
9. A method according to claim 8 , wherein said wheel is moved away from, and towards to, said support structure by said clamping elements.
10. A method according to claim 1 , wherein said disassembling step comprises removing an inflation valve built-into said tired-wheel by pulling said inflation valve off.
11. A method according to claim 10 , comprising fitting a new inflation valve.
12. A method according to claim 1 , comprising the step of automatically inflating said tire after the same has been fitted onto said wheel rim.
