Automatic tyre removal and mounting device and tyre removal machines equipped therewith

An automatic device for mounting and removing a tyre (6) onto and from a wheel rim (5),

• comprising a lower base (2) having an upper surface from which a rotary shaft (3) projects for supporting a support and a locking means (4) for the wheel rim (5);
• means positioned inside the base (2) for moving the shaft (3) in a direction orthogonal to an axis thereof;
• a vertical frame (7) supported by the base (2), and a carriage (8) moveable vertically on said frame;
• a hollow shaft horizontally supported by said carriage, and aligned with the rotary shaft;
• said hollow shaft supporting at a free end thereof an operating head (16) having a tyre demounting tool projecting radially therefrom;
• the tyre demounting tool (25) being hinged to the operating head and pivotable about an horizontal axis orthogonal to the axis of the hollow shaft;
• and
• operating means for positioning the tyre demounting tool in a first position in which the tool (25) is inclined towards a center of the wheel rim, and in a second position in which the tool (25) is perpendicular to the axis of the hollow shaft.
