A tyre mounting/dismounting machine (1), comprising a base (2), rotating means (3) for supporting and blocking a wheel (100) and a column (4) associated to the base (2), a first arm (7) and a second arm (8) being slidably mounted on the column (4), an upper first debeader tool (13) and a lower second debeader tool (9) being mounted respective at free ends of each arm (7, 8). Mounted at the free end of the first arm (7) is a head (10) which is rotatable with respect to an axis (Y), from which head a mounting tool (11), a dismounting tool (12) and the first debeader tool (13) project, the tools (11, 12, 13) being mounted in reciprocal positions such that the tools (11, 12, 13) do not interfere with one another and such that by rotating the head (10) with respect to the first arm (7) a same work position can be reached for each of the tools (11, 12, 13). Means for blocking (14, 15, 16, 17) are associated to the head (10) in three different positions, a same work position for each of the tools (11, 12, 13) corresponding to each of the three different positions.
1). A tyre mounting/dismounting machine (1), comprising:
2). The machine (1) of claim 1, wherein the column (4) is mobile in a nearing and distancing direction from the means (3) for supporting and blocking the wheel (100).
3). The machine (1) of claim 2, wherein the column (4) is activated to near and distance the means (3) for supporting and blocking by means of a jack (30) housed on the base (2).
4). The machine (1) of claim 1, wherein the first arm (7) and the second arm (8) are activated to slide along the column (4) by means of a first jack (40) and a second jack (41) associated to the column (4).
5). The machine of claim 1, wherein the first arm (7) and the second arm (8) are fixed removably to a respective slide (5, 6) of the slides (5, 6) which are slidable along rails (49) fixed to the column (4).
6). The machine (1) of claim 1, wherein the axis (Y) about which the head (10) rotates is arranged such as substantially to cross the rotation axis (X) of the means (3) for supporting and blocking.
7). The machine (1) of claim 6, wherein the rotation axis (Y) of the head (10) is arranged perpendicular with respect to the rotation axis (X) of the means (3) for supporting and blocking.
8). The machine (1) of claim 1, wherein the tools (11, 12, 13) mounted on the head (10) are arranged radially at a step of 120° from one another.
9). The machine (1) of claim 1, wherein the first debeader tool (13) is formed by a circular body rotatably mounted on the head (10) such as to rotate idly with respect to an axis passing through a centre thereof, the circular body exhibiting a concavity facing towards the means (3) for supporting and blocking.
10). The machine (1) of claim 1, wherein the mounting tool (11) is formed by a bar fixed at an end thereof to the head (10).
11). The machine (1) of claim 1, wherein the dismounting tool (12) is formed by an oblong body fixed at an end thereof to the head (10) and exhibiting at a free end thereof a hook conformation.
12). The machine of claim 1, wherein the means for blocking comprise three radial appendages (14) which extend from the head (10) and are interposed between the tools (11, 12, 13), each appendage (14) being provided with a through-hole (15) which locates at a further hole afforded in the block (16) fixed to the first arm (7) in order to be crossed by a blocking bolt (17).
13). The machine (1) of claim 1, wherein the column (4) is vertically arranged.
14). The machine (1) of claim 1, wherein the first debeader tool (13) and the second debeader tool (9) are symmetrically mounted with respect to one another on a plane which is perpendicular to the rotation axis (X) of the means
