Abstract
A machine for fitting and removing a tyre from a corresponding rim of a wheel of a vehicle, comprising: a wheel-holder unit rotating about a first axis (A) and slidably coupled to a groove provided in a base; a column; an upper operating head, provided with at least one upper fitting tool, at least one further tool, angularly spaced from the upper fitting tool, by a predetermined angle, and a wall pressing tool that can be placed in a working position which is operatively in contact with the wheel simultaneously with the upper fitting tool.

A machine for fitting and removing a tyre from a corresponding rim of a wheel for a vehicle, comprising:
- a wheel-holder unit that is rotatable about a first vertical axis of rotation;
- a base provided with a groove, wherein the groove guides a movement of the wheel-holder unit with respect to the base;
- a column having a guide oriented vertically;
- an upper arm having a first end and a second end;
- an upper carriage coupled to the guide of the column and connected to the first end of the upper arm;
- an upper operating head, connected to the second end of the upper arm and provided with an upper fitting tool, the upper fitting tool defining a lever having an elongate shape along a longitudinal direction, and being configured to be operatively inserted between a bead of the tyre and an annular edge of the corresponding rim, in an operating configuration in which the upper fitting tool is oriented towards the wheel, to be positioned in a working position in contact with the tyre by translation of the upper operating head;
- a wall pressing tool connected to the upper operating head and oriented in a direction concordant with the upper fitting tool for being positioned simultaneously with the upper fitting tool in a working position, wherein the wall pressing tool and the upper fitting tool are both;
- simultaneously in contact with the tyre of the wheel positioned on the wheel-holder unit;
- wherein the upper operating head includes a connecting arm, the connecting arm having a first end, connected to the upper operating head or to the upper fitting tool, and a second end;
- and,
- wherein the wall pressing tool includes a contact element rotatably coupled to the second end of the connecting arm.
A machine for fitting and removing a tyre from a corresponding rim of a wheel for a vehicle, comprising:
- a wheel-holder unit that is rotatable about a first vertical axis of rotation;
- a base provided with a groove, wherein the groove guides a movement of the wheel-holder unit with respect to the base;
- a column having a guide oriented vertically;
- an upper arm having a first end and a second end;
- an upper carriage coupled to the guide of the column and connected to the first end of the upper arm;
- an upper operating head, connected to the second end of the upper arm, rotating about a second axis of rotation, provided with an upper fitting tool having an elongate shape along a longitudinal direction, to be operatively inserted between a bead of the tyre and an annular edge of the corresponding rim, and provided with at least one further tool, angularly spaced from the upper fitting tool by a predetermined angle, so that the tools are alternatively selectable by rotating the upper operating head in respective operating configurations in which they are oriented towards the wheel to be positioned in a working position in contact with the tyre by translation of the upper operating head;
- a lower operating head, coupled to the second end of a lower arm, the second end of the lower arm being slidably coupled to the column, the lower operating head being rotatable and provided with a first lower tool and a second lower tool, the first lower tool and the second lower tool being spaced radially by a predetermined angle, to be selectively and alternatively positioned in an operating configuration by rotation of the lower operating head, wherein the first lower tool is configured to adopt an active position and a rest position, and is rotatable about a fourth axis, transverse to an axis of rotation of the lower operating head, to pass from the rest position to the active position.
A machine for fitting and removing a tyre from a corresponding rim of a wheel for a vehicle, comprising:
- a wheel-holder unit rotating about a first vertical axis of rotation;
- a base provided with a groove, wherein the groove guides a movement of the wheel-holder unit with respect to the base;
- a column having a guide oriented vertically;
- an upper arm having a first end and a second end;
- an upper carriage coupled to the guide of the column and connected to the first end of the upper arm;
- an upper operating head, connected to the second end of the upper arm, provided with at least one upper fitting tool defining a lever having an elongate shape along a longitudinal direction, to be operatively inserted between a bead of the tyre and an annular edge of the corresponding rim, in an operating configuration in which the at least one upper fitting tool is oriented towards the wheel, to be positioned in a working position in contact with the tyre by translation of the upper operating head;
- a lower operating head, coupled to the second end of a lower arm and provided with at least one tool configured to operatively act on a lower bead of the tyre, the second end of the lower arm being slidably coupled to the column;
- a wall pressing tool, connected to the upper operating head and oriented in a direction concordant with the at least one upper fitting tool, for being positioned simultaneously with the at least one upper fitting tool in a working position, wherein the wall pressing tool and the at least one upper fitting tool are both, simultaneously in contact with the tyre of the wheel positioned on the wheel-holder unit, wherein the wall pressing tool is rotatably mounted to a second end of a connecting arm that is connected to the upper operating head at a first end.
