US 12,233,673 B2 · Tyre-removal apparatus with automatically pivoting tool

Abstract

A tyre-removal apparatus includes a base having a support for receiving and rotating a wheel, and a frame joined to the base having an upright with a longitudinal axis substantially parallel to an axis of rotation of the wheel. A support arm associated with the upright is movable substantially parallel to the axis of rotation of the wheel. A tool for operating on the wheel is mounted pivoting on the support arm. A sensor associated with the tool detects a parameter representing contact between the tool and the wheel, and is connected to a control unit controlling an actuator associated with the support arm, to pivot the tool between a withdrawn position with respect to the axis of rotation of the wheel and an advanced position with respect to the axis of rotation of the wheel, depending on the parameter representing contact between the tool and the wheel.

Apparatus for mounting a tyre on a rim of a wheel and/or for removing a tyre from a rim of a wheel of a vehicle, comprising:

a base having a support for receiving and rotating the wheel;
a frame joined to the base and having an upright with a longitudinal axis substantially parallel to an axis of rotation of the wheel;
a support arm associated with the upright and movable in a direction substantially parallel to the axis of rotation of the wheel;
a tool for operating on the wheel, said tool being mounted pivoting on the support arm;
a sensor associated with the tool and able to detect at least one parameter representing contact between the tool and the wheel,
characterized in that
the sensor is operationally connected to a control unit able to control an actuator, associated with the support arm, so as to pivot the tool between a first withdrawn position with respect to the axis of rotation of the wheel and a second advanced position with respect to the axis of rotation of the wheel, depending on the at least one parameter representing the contact between the tool and the wheel.

Method for removing a tyre from a rim of a wheel of a vehicle, comprising the steps of:

clamping a wheel comprising a rim and a tyre on a support for receiving and rotating the wheel about an axis of rotation;
positioning a tool for operating on the wheel, in the vicinity of a first edge of the rim of the wheel, said tool being mounted pivoting on a support arm;
moving the support arm along a direction substantially parallel to the axis of rotation of the wheel;
rotating the support;
detecting, with a sensor associated with the tool, at least one parameter representing contact between the tool and the wheel,
characterized in that it comprises the step of:
sending a signal, relating to the at least one parameter, representing the contact between the tool and the wheel, to a control unit able to control an actuator so as to pivot the tool, and the step of:
pivoting the tool between a first withdrawn position with respect to the axis of rotation of the wheel and a second advanced position with respect to the axis of rotation of the wheel, depending on the at least one parameter representing the contact between the tool and the wheel.
