(Operation of the second invention)
In the tire balance correcting device of the second invention having the above-described configuration, the curable material adhesion amount control means (C18a) at the time of setting the adhesion angle upper limit of the curable material adhesion amount control means (C18) is a unit of the curable material. A circle determined by the adhesion angle upper limit setting value θ1a by keeping the discharge weight m of time constant, setting the adhesion angle θ1 to the upper limit setting value θ1a, and adjusting the rotation angular velocity ω of the rotary table (11). The weight of the curable material that adheres in the range of -θ1a ≦ θ1 ≦ θ1a in the arc-shaped material attachment region is controlled.
In this case, the curable material can be adhered in a thinly dispersed state within the range of -θ1a ≦ θ ≦ θ1a (relatively wide range) of the arc-shaped material adhesion region on the inner surface of the tire, so that the curable material is swelled in a narrow region. As compared with the case where the tire is made, it is possible to prevent the curable material from peeling off or detaching from the inner surface of the tire (T).
Further, in the second invention, the adhesion angle θ1 is set to an upper limit set value θ1a, and θ1a which defines the range of −θ1a ≦ θ1 ≦ θ1a of the arc-shaped material adhesion region determined by the rotation position θ1a is set to θ1a ≦ π / 6.

In the case of (π / 60)> θ1a, the area of the curable material adhering to the arc-shaped material adhering area becomes smaller, so that the adhesive force of the curable material to the arc-shaped material adhering area becomes smaller, and the material adhering area becomes smaller. It is easy to break off from Therefore, by setting (π / 60) ≦ θ1a, it is possible to prevent the adhesion of the curable material to the arc-shaped material attachment region from decreasing. For this reason, the adhesion area of the curable material to the tire inner surface increases, and the adhesive force of the curable material to the tire inner surface increases. Since the tire (T) repeatedly undergoes elastic deformation while the vehicle is running, if the adhesive force of the curable material to the inner surface of the tire is small, peeling or detachment of the curable material from the arc-shaped material attachment region occurs. However, as described above, by setting (π / 60) ≦ θ1a, the adhesive force of the curable material to the tire inner surface is increased, and the curable material is separated from the arc-shaped material adhered region.

(Operation of First Embodiment)
In the tire balance correcting apparatus according to the first embodiment having the above-described configuration, the rotary table 11 includes a circumferential position of a light point which is a position opposite to a center of gravity of the tire with respect to a center line of the tire, and the center of gravity. The tire having the unbalanced moment M0 (M0 = Wr (gcm)) determined by the amount of eccentricity r from the center line and the weight W of the tire is detachably supported. When the tire T is fixedly supported on the rotary table 11, the light point position of the tire T is fixed in a state in which it matches a predetermined position (reference position) in the circumferential direction of the rotary table 11.
The unbalanced moment amount M0 is input by a ten-key UIa after inputting an unbalanced moment amount input designation key UIa of a UI (user interface).

The material attachment radius storage means C8 stores a radius R (cm) of the arc-shaped material attachment region on the inner surface of the tire from the tire center line.
The discharge weight range per unit time storage means C9 stores the upper limit set value (ma) and the lower limit set value (mb) of the range of the discharge weight m of the curable material per unit time.
The table rotation speed range storage means C10 stores an upper limit set value (ωa) and a lower limit set value (ωb) of the rotation angular speed ω of the rotary table.
During one rotation, the maximum balance adjustment amount determining means C11 performs the rotation of the rotary table during one rotation according to the upper limit setting angle θ1a, the upper limit setting value ma of the discharge weight m, and the lower limit setting value ωb of the rotation angular velocity ω. The maximum balance adjustment amount per rotation {(ma / ωb) · 2Rsin θ1a} determined by the maximum weight of the curable material that adheres to the arc-shaped material attachment region {(ma / Rωb) · 2Rθ1a} is determined.

  The adhesion angle range setting means C15 includes a range of θ (−θ1 ≦ θ ≦ θ1) set to limit the range of the arc-shaped material adhesion region where the curable material discharged from the nozzle adheres to the inner surface of the rotating tire. ) Is set. The discharge execution rotation position setting means C16 is for adhering the curable material discharged from the nozzle 34 to the inner surface of the tire T which makes one revolution, in the range of the arc-shaped material adhesion region determined by the adhesion angle θ1 (radian). Of the light point at which the curable material is to be discharged (−θ1−α) ≦ θ ≦ (θ1−α), and the calculated value is set.

The rotation control means C2 controls the operation of the table driving device (D2 + M2) to rotate the rotary table 11 and the tire T at a set rotational angular velocity ω.
The light point rotational position detecting means C17 detects the rotational position θ of the reference position of the rotary table 11 (that is, the light point position of the tire) with respect to the nozzle 34 based on the detection signal of the rotary table rotational position sensor SN1. The curable material adhesion amount control unit C18 switches the switching valve V to the discharge position when the rotation position θ of the light point is (−θ1−α) ≦ θ ≦ (θ1−α). The curable material for adjusting the moment amount M0 is discharged. The unbalanced moment M0 is corrected by the curable material discharged from the nozzle 34 adhering to the arc-shaped material adhering region on the inner surface of the tire T.

When the unbalanced moment amount M0 is larger than the maximum balance adjustment amount {(ma / ωb) · 2Rsin θ1a} during one rotation, the curable material adhesion amount control unit C18 repeats the tire T multiple times (for example, n), the curable material is discharged during each rotation and adheres to the inner surface of the tire T to correct the unbalanced moment M0.
During the second and subsequent rotations of the plurality of rotations (n times), the curable material adhesion amount control means C18a at the time of setting the upper limit of the adhesion angle of the curable material adhesion amount control means C18 performs By keeping the discharge weight m per unit time constant, setting the adhesion angle θ1 to the upper limit set value θ1a, and adjusting the rotation angular velocity ω of the rotary table, an arc-shaped material determined by the adhesion angle upper limit set value θ1a The weight of the curable material adhering in the range of -θ1a ≦ θ1 ≦ θ1a in the adhesion region is controlled.

In this case, the correction amount of the unbalance moment amount during each of the second and subsequent rotations of the plurality of (n) rotations is the maximum balance adjustment amount {(ma / ωb) · 2Rsin θ1a} during one rotation. . When the maximum balance adjustment amount {(ma / ωb) · 2Rsin θ1a} during one rotation is repeated a plurality of times ((n−1) times), the total imbalance correction amount is (n−1) ｛(ma / ωb). ) · 2Rsinθ1a｝ The difference between the unbalanced moment amount M0 and (n-1) {(ma / ωb) · 2Rsin θ1a} can be expressed by the following equation.
[M0− (n−1) ｛(ma / ωb) · 2Rsin θ1a｝]... (5)
The value of the above equation (5) (the remaining unbalance moment that cannot be corrected by the balance correction of (n-1) rotations) is greater than 0 and not more than the maximum balance adjustment amount {(ma / ωb) · 2Rsin θ1a} during one rotation. In the case of (1), the “remaining unbalance moment amount” expressed by the above equation (5) is adjusted during the first rotation.
In the first embodiment, the adjustment of the “remaining unbalance moment” expressed by the above equation (5) is performed by correcting the balance during the first rotation of the n rotations. It is also possible to correct the balance during rotation.

The unbalance moment amount M0 corrected during the first rotation of the plurality of rotations is equal to or less than the maximum balance adjustment amount {(ma / ωb) · 2Rsin θ1a} during the one rotation and a predetermined set value 設定 (mb / ωa). If it is larger than 2R sin θ1a｝, the curable material adhesion amount control means C18a at the time of setting the adhesion angle upper limit of the curable material adhesion amount control means C18 keeps the discharge weight m of the curable material per unit time at a constant ma. Further, by setting the adhesion angle θ1 to the upper limit set value θ1a and adjusting the rotational angular velocity ω of the rotary table, the range of −θ1a ≦ θ ≦ θ1a of the arc-shaped material adhesion region determined by the adhesion angle upper limit set value θ1a. Controls the weight of curable material that adheres to the surface.
As described above, by setting the adhesion angle θ1 to the maximum value (upper limit value) θ1a, the adhesion area of the curable material to the tire inner surface increases, so that the adhesive force of the curable material to the tire inner surface increases. Become. For this reason, peeling or detachment of the curable material from the arc-shaped material attachment region can be prevented.

The unbalanced moment amount M0 to be corrected during the first rotation of the plurality of rotations is calculated by subtracting the minimum adhesion weight m2 = (mb / Rωa) of the curable material per unit length of the arc-shaped material adhesion region from the circle. When it is smaller than the maximum balance adjustment amount per rotation (mb / ωa) 2Rsinθ1a at the time of the minimum adhesion weight when it is attached to the maximum length 2Rθ1a of the arc-shaped material adhesion region, the curable material adhesion amount control means C18 The curable material adhesion amount control means C18b at the time of setting the ejection weight lower limit sets the rotation angular velocity ω to ω = ωa, sets the ejection weight m = mb, and adjusts the adhesion angle θ1.
As described above, by setting the rotational angular velocity ω to the maximum (upper limit value) ωa and setting the ejection weight m to the minimum value (lower limit value) mb, the adhesion angle θ1 can be increased. For this reason, the adhesion area of the curable material to the tire inner surface increases, and the adhesive force of the curable material to the tire inner surface increases. For this reason, peeling or detachment of the curable material from the arc-shaped material attachment region can be prevented.

As described above, when the tire T is rotated a plurality of times, and the curable material is discharged during each rotation and adhered to the inner surface of the tire T to correct the unbalanced moment amount M0, the embodiment 1 The nozzle position control means C3 stops the elevating table 6 so as to discharge the curable material to the same position on the inner surface of the tire during each rotation, and holds the position of the nozzle in a stopped state.
In this case, since the curable material is attached to the arc-shaped material attachment region on the inner surface of the tire in a plurality of times, a large amount of the curable material is formed in comparison with a case where a large amount of the curable material is ejected and attached at a time. It is possible to reduce the amount of the curable material that has been discharged, and to uniformly adhere the curable material.

An ultraviolet irradiation light source arranged opposite to a moving path of the curable material discharged and attached to the inner surface of the rotating tire irradiates the curable material made of an ultraviolet curable resin with ultraviolet light. For this reason, when the curable material discharged and adhered to the arc-shaped material adhered region of the tire T is cured, the tire T can be cured on the spot without being transported to an ultraviolet irradiation chamber or the like. Correction work efficiency is improved.
Further, in the first embodiment, the nozzle 34 is disposed so as to face the inner surface of the tread (portion to be grounded) of the tire T that rotates together with the turntable 11, and the ultraviolet curable material discharged from the nozzle 34 is Adhere to the arc-shaped material attachment area on the inner surface of the. Since the inner surface of the tread of the tire T has a large area and a substantially constant radius, the ultraviolet curable material can be easily attached to a region having a constant radius. Since the ultraviolet curable material can be easily attached to the region having a constant radius while rotating the tire T, the work of correcting the unbalance moment M0 of the tire T can be performed in a short time. In addition, since the inner surface of the tread has a small amount of deformation, the ultraviolet curable material adhered to that portion is not easily peeled off.

As mentioned above, although the Example of this invention was described in full detail, this invention is not limited to the said Example, Various changes are made within the range of the gist of this invention described in the claim. It is possible. Modified embodiments of the present invention are exemplified below.
(H01) In Example 1 of the present invention, when correcting the unbalanced moment amount M0 by rotating the tire a plurality of times and discharging the curable material during each rotation and attaching the curable material to the tire inner surface, Instead of discharging the curable material to the same position on the inner surface of the tire during each rotation, the curable material is discharged to a different position on the inner surface of the tire during at least one of the plurality of rotations than during the other rotations. It is possible to provide a nozzle position control means capable of adjusting the position of the nozzle. The adjustment of the position of the nozzle can be performed by moving the elevating table 6 up and down. In addition, it is also possible to configure so that the direction of the nozzle can be adjusted. In this case, it is possible to change the position where the curable material adheres to the inner surface of the tire T by adjusting the direction of the nozzle.
(H02) When the curable material is discharged and adhered to the different inner surface positions of the tire, the radius from the rotation center of the curable material adhesion region is the same as the radius from the rotation center of the other curable material adhesion region during rotation. Is adjustable.
(H03) When the curable material is ejected and adhered to the different tire inner surface positions, the radius of the curable material adhered region from the rotation center is different from the radius of the other curable material adhered region during rotation. The position of the nozzle can be adjusted to a value.

(H04) In the above embodiment, the attachment angle θ1 is set to the upper limit set value θ1a, and θ1a that defines the range of −θ1a ≦ θ1 ≦ θ1a of the arc-shaped material attachment region determined by the rotation position θ1a is θ1a ≦ π / 6. Can be set to In this case, there are the following advantages. That is, assuming that the weight per unit length of the curable material attached to the arc-shaped material attachment area is m, the weight contributing to the correction of the unbalanced moment M0 is m · m. cos θ. Therefore, as the value of θ increases, the weight of the weight m that contributes to the correction of the unbalanced moment M0 decreases, and the weight of the entire tire increases. However, when θ1a ≦ (π / 6) is set, it is possible to prevent the above problem from occurring.
(H05) In the above embodiment, it is possible to set (π / 60) ≦ θ1a. In this case, it is possible to prevent the adhesion area of the curable material to the arc-shaped material attachment region from becoming small. For this reason, the adhesion area of the curable material to the tire inner surface increases, and the adhesive force of the curable material to the tire inner surface increases. Since the tire repeatedly undergoes elastic deformation during running of the vehicle, if the adhesive force of the curable material to the tire inner surface is small, peeling or detachment of the curable material from the arc-shaped material attachment region is likely to occur. However, as described above, by setting (π / 60) ≦ θ1a, the adhesive force of the curable material to the inner surface of the tire increases, and the curable material peels or separates from the arc-shaped material adhered region. Can be prevented.

(H06) In the balance correcting device of the third embodiment, the wheel S is rotated a plurality of times, and the curable material is discharged and adhered to the inner surface of the side surface of the wheel H during each rotation to correct the unbalance moment M0. In this case, a plurality of ring-shaped recesses having different radii are formed, and the curable material is formed in a ring-shaped recess different from other rotations during at least one of the plurality of rotations by the nozzle position control means. It is possible to adjust the position of the nozzle so as to discharge the ink.
(H07) The ultraviolet irradiation light source of the present invention can be constituted by one or more ultraviolet lamps 37.
(H08) Further, as the ultraviolet irradiation light source, an arc-shaped material adhering area in the range of -θ1 ≦ θ ≦ θ1 on the inner peripheral surface of the tire T or an arc-shaped material in the range of -θ1 ≦ θ ≦ θ1 of the ring-shaped concave portion of the wheel T It is possible to use an ultraviolet irradiation light source that can irradiate ultraviolet light only to the material adhesion area, or an ultraviolet irradiation light source that can irradiate ultraviolet light to the entire circumference of the tire inner peripheral surface or the entire circumference of the ring-shaped concave portion. is there.
(H09) When irradiating the ultraviolet-curable material with ultraviolet rays in order to cure the ultraviolet-curable material adhered to the arc-shaped material-attached region, irradiation may be performed while the tire T or the wheel S is stopped, or the (rotation stopping step). ) It is possible to irradiate while rotating.
