[0069] With reference to the accompanying drawings, the numeral 1 denotes an apparatus for mounting a tyre P on a respective rim C of a vehicle wheel R.

[0070] The apparatus 1 comprises a frame 100. The frame 100 comprises a base unit 101, resting on the floor. The frame 100 comprises a column 102 which rises from the base unit 101 along an axial orientation A.

[0071] In an embodiment, the frame 100 comprises a first operating arm 103, connected to the column 102. The first operating arm 103 extends from the column 102 parallel to the axial orientation A.

[0072] In an embodiment, the frame comprises a second operating arm 104. The first operating arm 103 and the second operating arm 104 are configured to hold tools adapted to mount the tyre P on the respective rim C. In an embodiment, the apparatus 1 comprises only the first operating arm 103, for all the mounting tools, both those for seating the bead and those to facilitate mounting operations.

[0073] The apparatus comprises a working tool 2 which is movable relative to the frame 100 (relative to the column 102) towards the wheel R to come into contact with the tyre P. The working tool 2 is movable along the axial orientation A (towards and away from the wheel R) relative to the first arm 103 and/or along a transverse orientation T perpendicular to the axial orientation A, relative to the column 102 (or more generally speaking, relative to the frame 100).

[0074] The apparatus comprises a chuck 3, connected to the base unit 101 of the frame 100. The chuck 3 rotates relative to the frame 100 about an axis of rotation R1, parallel to the axial orientation A.

[0075] In an embodiment, the chuck 3 is movable relative to the frame along the transverse orientation T. In other possible solutions of this disclosure, the chuck 3 is movable relative to the frame 100 along the axial orientation A.

[0076] According to an aspect of this disclosure, the frame comprises an axial actuator 105. In an embodiment, the axial actuator 105 is connected to the base unit 101 and rises along the axial orientation A.

[0077] In other embodiments, the axial actuator 105 is connected to (built into) the column 102.

[0078] In an embodiment, the second operating arm 104 is connected to the axial actuator and extends from it perpendicularly to the axial orientation. In other embodiments, the second operating arm 104 extends from the column 102 perpendicularly to the axial orientation A.

[0079] The apparatus 1 (the frame 100) comprises a supporting element 106. The supporting element is connected to the axial actuator 105. In an embodiment, the supporting element 106 is connected to the column 102 and is slidable relative to the column 102 along the axial orientation A.

[0080] In an embodiment, the axial actuator 105 comprises a cylinder 105A and a piston 105B. The cylinder 105A is fixed to the base unit 101 of the frame 100. The piston 105B is movable relative to the frame along the axial orientation A. The supporting element 106 is connected to the piston 105B (to a stem of the piston 1058) to move along the axial orientation A.

[0081] In an embodiment, the apparatus 1 comprises a bead seating device 4.

[0082] The bead seating device 4 is configured to seat the tyre P on the rim C of the wheel R. Bead seating is a preliminary operation for inflating the wheel R (with specific inflation parameters such as, for example, high flow rates), whereby the beads of the tyre P are bedded in the respective seats of the rim C before inflation of the wheel R is completed. The bead seating device 4 is therefore configured to generate an air flow to be injected between a flange of the rim and a bead of the tyre.

[0083] The bead seating device 4 includes a rigid element 401. The rigid element 401 is, for example, a rigid rod that extends along the transverse orientation T. The bead seating device 4 includes a slideway 402. The slideway 402 is connected to the supporting element 106. The rigid element 401 is coupled to the slideway 402. The rigid element 401 is movable relative to the slideway 402 along the transverse orientation T.

[0084] The rigid element 401 is movable inside the slideway 402 along the transverse orientation T.

[0085] According to an aspect of this disclosure, the bead seating device can be actuated manually or automatically by a transverse actuator.

[0086] In the case of manual actuation, the slideway 402 is a hollow box configured to guide the rigid element 401 during the sliding movement imparted to it by an operator. In the case of automatic actuation, the rigid element 401 is, for example, a stem of a piston of the transverse actuator (for example, a pneumatic reciprocating actuator) and the slideway 402 is defined by a cylinder of the transverse actuator. In this embodiment, the transverse actuator is connected to the supporting element 106 which entrains it along the axial orientation A. This embodiment is purely exemplary and automatic actuation might involve the use of an electric actuator.

[0087] It should also be noted that in a further embodiment, the bead seating device 4 might be actuated by a hybrid system. For example, the bead seating device 4 might be moved by the transverse actuator in an initial step of approaching, after which its position would be adjusted manually.

[0088] The bead seating device 4 is movable relative to the frame 100 (relative to the slideway 402) between a rest position P1, in which the bead seating device 4 is spaced from the rim C, and a working position P2, in which the bead seating device 4 is interposed between the flange of the rim C and the bead of the tyre P.

[0089] The bead seating device comprises an injection nozzle 403. The bead seating device comprises a duct 404. The duct 404 is configured to convey the air flow to the injection nozzle 403.

[0090] The duct 404 is, for example, a flexible hose connected to a compressor which supplies the air flow to be injected.

[0091] The injection nozzle 403 is configured to direct the air flow. The injection nozzle 403 is connected to the rigid element 401 to move with it along the transverse orientation T. The injection nozzle 403 is connected to the duct 404 to receive the air flow.

[0092] In an embodiment, the bead seating device 4 comprises a locking element 405. The locking element 405 is configured to lock (constrain) the rigid element 401 to the frame 100 (to the slideway 402) when the bead seating device 4 is at the working position P2. The locking element 405 is configured to inhibit the rigid element 401 from sliding in the slideway 402 when the bead seating device 4 is at the working position P2.

[0093] In an embodiment, the locking element 405 may be integrated in the transverse actuator to lock in place a movable element of the transverse actuator—for example, a piston in the case of a reciprocating actuator. In other embodiments, the locking element 405 is a threaded member which is screwed transversely (in the direction of movement of the rigid element 401 in the slideway 402) into a respective threaded socket of the slideway 402.

[0094] Therefore, the further the tip of the threaded member is screwed in, the greater the pressure it exerts on the rigid element 401. This pressure increases friction between the threaded member and the rigid element 401 until the value of that friction is high enough to counteract the forces caused by the injection of the air flow.

[0095] In an embodiment, the injection nozzle 403 is included in an injection plane P1. The injection plane is inclined to the transverse orientation T, that is to say, inclined to the predominant orientation of the rigid element 401.

[0096] The injection nozzle 403 comprises a first portion 403′ having a single flow section. The first portion 403′ is connected to the duct 404 to receive the air flow along a conveying orientation DC, preferably included in the injection plane PI. The injection nozzle 403 comprises a second portion 403″. The second portion 403″ comprises a first air flow section and a second air flow section which branch out from the single flow section of the first portion 403′.

[0097] More specifically, the injection nozzle 403 comprises a first opening 403A and/or a second opening 403B. The first opening 403A is associated with the first flow section to define a first air flow injection orientation D1. The second opening 403B is associated with the second flow section to define a second air flow injection orientation D2.

[0098] The first injection orientation D1 and/or the second injection orientation D2 are included in the inclination plane PI (that is, they are inclined to the transverse orientation T). The first injection orientation D1 and/or the second injection orientation D2 are inclined to each other). The first injection orientation D1 and/or the second injection orientation D2 are convergent, in the inclination plane, along the conveying orientation DC in a direction oriented from the second portion 403″ to the first portion 403′ of the injection nozzle 403.

[0099] Moreover, in a further embodiment, the second portion of the injection nozzle 403 might be divided into a plurality of flow sections, each having a respective opening and a respective injection orientation.

[0100] It should be noted that the nozzle might, in one embodiment, comprise only the first portion 403′, preferably with a constant cross section size, extending to the opening of the nozzle.

[0101] In an embodiment, the transverse orientation T is a radial orientation passing through the axis of rotation R1 of the chuck 3. In such an embodiment, the conveying orientation DC also passes through the axis of rotation R1, but not perpendicularly thereto. In this embodiment, therefore, the first injection orientation D1 and the second injection orientation D2 are inclined at the same angle of deviation AD relative to the axis of rotation R1, thus improving inflation uniformity and bead seating efficiency. In other words, the plane which includes the rigid element 401 and the axis of rotation R1 of the chuck 3 define a bisector of the angle between the first injection orientation D1 and the second injection orientation D2.

[0102] In other embodiments, the angle of deviation of the first injection orientation D1 and the angle of deviation of the second injection orientation D2 are different but are located on opposite sides of the plane which includes the rigid element 401 and the axis of rotation R1 of the chuck 3.

[0103] The bead seating device 4 includes an abutment element 406. The abutment element 406 is configured to come into abutment against the wheel rim C when the bead seating device 4 is at the working position P2.

[0104] The abutment element 406 preferably has a curved profile so it can surmount the rim C. In an embodiment, the abutment element 406 is perpendicular to the injection plane PI and rises therefrom to come into abutment against the rim C when the injection nozzle 403 is disposed between the bead of the tyre P and the rim C. In an embodiment, the abutment element 406 is disposed at the injection nozzle 403, preferably interposed between the first opening 403A and the second opening 403B.

[0105] The abutment element 406 is connected to a top surface of the injection nozzle 403, facing the flange of the rim C.

[0106] According to an aspect of this disclosure, the apparatus 1 comprises an inflator 5. The inflator 5 is configured to inflate the tyre P mounted on the rim C. More specifically, the inflator 5 is configured to complete inflation of the wheel R and thus comes into operation after the tyre P has been seated on the rim C.

[0107] The inflator 5 comprises one or more of the following features: [0108] an inflation duct, connectable to a valve of the rim C; [0109] optionally, a compressor, configured to generate an air flow to reach a desired inflation pressure; [0110] a pressure sensor, configured to detect the pressure inside the wheel; [0111] an inflation connector, located at one end of the inflation duct to connect to the valve of the rim; [0112] a pressure limiter, configured to interrupt air injection when the tyre pressure exceeds a threshold value.

[0113] In an embodiment, preferably in which the apparatus 1 is configured to automatically actuate the bead seating device 4 through the transverse actuator, the apparatus 1 comprises a control unit 6. The apparatus 1 comprises a user interface, configured to allow entering configuration data, preferably representing a diameter of the rim or, more generally speaking, geometrical characteristics of the wheel being mounted. In other embodiments, the configuration data are determined automatically through one or more sensors which are configured to detect the geometrical characteristics of the wheel being mounted.

[0114] The control unit 6 is configured to receive the configuration data. The control unit 6 is configured to generate drive signals in response to the configuration data. In an embodiment, the drive signals represent one or more of the following entities: the rest position P1 of the bead seating device 4, the working position P2 of the bead seating device 4, the maximum torque (force) deliverable by the transverse actuator, the axial position of the supporting element 106, the position of the working tool relative to the chuck 3. In an embodiment, the control unit is configured to receive control signals, for example from the transverse actuator. In an embodiment, the drive signals represent one or more of the following entities: the torque (force) delivered by the transverse actuator and/or by the axial actuator, the position of the bead seating device 4 relative to the chuck 3, the position of the chuck 3 relative to the frame 100.

[0115] In an embodiment, the control unit 6 is configured to determine the drive signals as a function of the control signals and of the configuration data.

[0116] In an embodiment, the control unit is programmed to disable the transverse actuator when the values of the delivered torque (force) exceed a limit torque (force) value (that is to say, the control unit includes a torque and/or force limiter). This prevents damage to the rim C if the working position P2 is calculated incorrectly and if the bead seating device 4 comes into contact with the rim C before reaching the working position P2.

[0117] In such a case, the resistance of the rim C increases the torque (force) delivered by the transverse actuator which, when the maximum torque (force) deliverable is exceeded, is disabled by a torque limiter of the control unit 6. This function may also be used for positioning. In effect, in an embodiment, the control unit 6 is configured to determine an axial position of the bead seating device 4 in response to the configuration data.

[0118] The control unit 6 is also configured to interrupt the transverse movement of the bead seating device 4 when it detects a minimum resistance, indicating that it has come into abutment against the rim C.

[0119] According to an aspect of it, this disclosure provides a method for mounting a tyre on a respective vehicle wheel rim.

[0120] The method comprises a step of providing a mounting apparatus 1 including a frame 100, a chuck 3 connected to the frame 100, a working tool 2 and a bead seating device 4.

[0121] The method comprises a step of positioning the tyre P on the rim C fixed to the chuck 3. In this step, the tyre P is only partly inserted into the correct seat of the rim C. More specifically, only one bead of the tyre P is interposed between the edges of the flange of the rim C.

[0122] In an embodiment, the method comprises a step of moving the working tool 2 into contact with the tyre P.

[0123] The method comprises a step of rotating the chuck 3 about the axis of rotation R1 of the wheel R in order to couple the tyre P to the rim C.

[0124] Through the step of moving the working tool 2 and the step of rotating the wheel R. the other bead of the tyre is also interposed between the edges of the flange of the rim C.

[0125] The method comprises a step of moving the bead seating device 4 relative to the chuck 3. The step of moving is performed along a transverse orientation T, perpendicular to the axis of rotation R1, between a rest position P1, in which the bead seating device 4 is spaced from the rim C, and a working position P2, in which the bead seating device 4 is interposed between the flange of the rim C and the bead of the tyre P.

[0126] The method comprises a step of seating the bead of the tyre P in the respective rim C by a step of the bead seating device 4 injecting an air flow between a flange of the rim C and a bead of the tyre P.

[0127] In the step of seating the bead, a rigid element 401 of the bead seating device 4 is constrained to the frame 100. The rigid element 401 receives a constraint force from the frame 100 to oppose the force generated by the air flow. This allows keeping the bead seating device 4 stationary at the working position P2 during the step of seating the bead.

[0128] The method comprises a step of moving a first operating arm 103 along an axial orientation A, parallel to the axis of rotation R1. The operating arm supports the working tool 2 and moves it along the axial orientation A.

[0129] In an embodiment, the method comprises a step of moving the chuck 3 along an orientation that is perpendicular to the axis of rotation R1 of the chuck 3. In addition, or alternatively, the chuck 3 is moved along the axial orientation A.

[0130] The method comprises a step of axially actuating. In the step of axially actuating, an axial actuator 105, connected to the base unit 101 and extending along the axial orientation A, moves along the axial orientation

[0131] A a supporting element 106 which supports the bead seating device 4.

[0132] Thus, an axial movement of the supporting element 106 also moves the bead seating device 4 along the axial orientation A.

[0133] The method comprises a step of sliding a rigid element 401 of the bead seating device 4 along the transverse orientation T in a slideway 402 of the bead seating device 4.

[0134] In an embodiment, the method comprises a step of manually actuating the bead seating device 4.

[0135] In the step of manually actuating, an operator moves the rigid element 401 relative to the slideway 402. The step of manually actuating also comprises a step of locking and/or unlocking. In the step of locking and/or unlocking, a locking element 405 inhibits the movement of the rigid element 401 relative to the slideway 402. For example, a threaded part inserted into the slideway 402 is screwed tight on the rigid element 401.

[0136] Tightening the rigid element 401 this way produces friction which makes the rigid element 401 become one with the frame 100 (with the slideway 402).

[0137] In addition, or alternatively, the method comprises a step of automatically actuating the bead seating device 4. In the step of automatically actuating, a transverse operator, preferably connected to the supporting element 106, moves the rigid element 401 relative to the slideway 402.

[0138] In the step of injecting, an injection nozzle 403 of the bead seating device 4 directs the air flow. In the step of injecting, a duct 404, connected to the injection nozzle 403, conveys the air flow to the injection nozzle 403. In the step of moving the rigid element 401, the injection nozzle 403, which is connected to the rigid element 401, is entrained in the movement along the transverse orientation T.

[0139] In the step of injecting, the injection nozzle 403 directs the air flow along an injection plane P1 that is inclined to the transverse orientation T, that is to say, inclined to the predominant orientation of the rigid element 401.

[0140] In an embodiment in which the injection nozzle comprises a first opening 403A and/or a second opening 403B through which the air flow is injected, the method comprises a first step of injecting and a second step of injecting. In the first step of injecting, the air flow is injected through the first opening 403A along a first injection orientation D1. In the second step of injecting, the air flow is injected through the second opening 403B along a second injection orientation D2.

[0141] In the step of injecting, the first injection orientation D1 and/or the second injection orientation D2 remain included in the inclination plane PI (that is, they are inclined to the transverse orientation T) and are inclined to each other. In the step of injecting, the first injection orientation D1 and/or the second injection orientation D2 are symmetrical about a plane which includes the rigid element 401 and the axis of rotation R1 of the chuck 3 (that is to say, the plane defines a bisector of the angle between the first injection orientation D1 and the second injection orientation D2).

[0142] In an embodiment, the method comprises a step of abutting. In the step of abutting, an abutment element 406 which is preferably perpendicular to the injection plane PI comes into abutment against the rim C when the bead seating device 4 is at the working position P2.

[0143] According to an aspect of this disclosure, the method comprises a step of inflating. In the step of inflating, an inflator 5 inflates the tyre P mounted on the rim C. More specifically, the inflator 5 completes inflation of the wheel R and thus comes into operation after the tyre P has been seated on the rim C. In the step of inflating, an inflation duct is connected to a valve of the rim C and to a compressor (or, alternatively, to a compressed air line which supplies the air flow through a compressor outside the apparatus), which generates an air flow at an inflation pressure. Also in the step of inflating, a pressure sensor, detects the pressure inside the wheel;

[0144] In an embodiment, preferably with the bead seating device 4 actuated automatically, the method comprises a step of controlling.

[0145] In the step of controlling, a control unit 6 receives configuration data, preferably representing a diameter of the rim, from a user interface.

[0146] The control unit 6 generates drive signals in response to the configuration data. In an embodiment, the control unit receives, for example from the transverse actuator, control signals representing one or more of the following entities: the torque (force) delivered by the transverse actuator, the position of the bead seating device 4 relative to the chuck 3, the position of the chuck 3 relative to the frame 100.

[0147] In an embodiment, the control unit 6 determines the drive signals as a function of the control signals and/or of the configuration data.

[0148] In an embodiment, the step of controlling comprises a step of limiting the deliverable torque. In the step of limiting the torque, the control unit disables the transverse actuator when the values of the torque (force) delivered exceed a limit torque (force) value (that is to say, the control unit includes a torque and/or force limiter). In an embodiment, the step of moving the bead seating device comprises a step of positioning by feedback. In the step of positioning by feedback, the control unit 6 determines an axial position of the bead seating device 4 in response to the configuration data. After that, the control unit 6 interrupts the transverse movement of the bead seating device 4 when it detects a minimum resistance, indicating that it has come into abutment against the rim C, hence that the bead seating device 4 has reached the working position P2.
