Shown in Fig. 7 (b) and 8 (b), by stretching out of bar portion 52, moving part 33 overcomes the motive force of second pushing part 43, slides and is pressed down along guide part 32.Along with the slip of moving part 33, cam part 27 is rotated guide part 32 run-off the straights.At this moment, main roller 11 can rotate on the direction that auxiliary wheel 12 is pressed down, that is: with regard to the first holding unit 6A, the rotation direction of main roller 11 is the clockwise direction (arrow D1) among the figure; With regard to the second holding unit 6B, the rotation direction of main roller 11 is the counter clockwise direction among the figure.Therefore, even impose resistance by 47 pairs of auxiliary wheels 12 of detent, main roller 11 still can rotate.As a result, do not have significant frictional force between main roller 11 and the auxiliary wheel 12 and occur, thereby auxiliary wheel 12 can be depressed.
Shown in Fig. 7 (c) and 8 (c), along with bar portion 52 continue stretch out, auxiliary wheel 12 is along with moving part 33 is directly upwards inwardly pressed down at tire together, and directly upwards separates certain clearance with main roller 11 at tire.Then, casingply sheet Cp is set in the gap between main roller 11 and the auxiliary wheel 12.
In addition, in each holding unit 6A and 6B, when the pressure-air in the cylinder barrel 51 of actuator 13 was released, bar portion 52 was withdrawn in the cylinder barrel 51.Therefore, under the effect of second pushing part 43, moving part 33 is raised along guide part 32, thereby can slide on the direction of cam part 27.
Therebetween, shown in Fig. 9 (a), auxiliary wheel 12 is raised with moving part 33, thereby levels off to main roller 11.Thereby, in each holding unit 6A and 6B, main roller 11 contacts at the outer surface Cpo that tire directly makes progress with body piles Cp, and auxiliary wheel 12 contacts at the inner surface Cpi that tire directly makes progress with casingply sheet Cp, thereby clamps casingply sheet Cp (see figure 1).
In addition, shown in Fig. 9 (b), by one-way clutch 35 (as shown in Figure 6), main roller 11 direction that is raised along auxiliary wheel 12 that is under an embargo is rotated, that is: with regard to the first holding unit 6A, main roller 11 rotation on counterclockwise in the drawings is under an embargo; With regard to the second holding unit 6B, main roller 12 rotation on the clockwise direction in the drawings is under an embargo.And, because detent 47 applies the rotation (as shown in Figure 6) of resistance to auxiliary wheel 12, produce significant frictional force between auxiliary wheel 12 and the main roller 11.So, across casingply sheet Cp when the excircle of main roller 11 slowly rotates, auxiliary wheel 12 is promoted to itself and main roller 12 position when tire axial is arranged shoulder to shoulder.Auxiliary wheel 12 is a kind of desirable situations along the slow lifting of main roller 11, caused its maintained position (holding position) to be offset because can prevent casingply sheet Cp like this because of involving fast, also can prevent to be spurred by accident the generation of the fold that is caused because of casingply sheet Cp.Must notice that the setting of detent 47 is optionally, detent 47 can be omitted.
Figure 10 (a) and (b) show state when the pressure F greater than first pushing part, 36 motive forces acts on main roller 11.In this case, in renitency F, main roller 11 can be guided by cam part 27 with moving axially portion 10, and outwards moves along tire axial.
As pressure F during less than the motive force of first pushing part 36, main roller 11 moves inward along tire axial with moving axially portion 10.By the first such pushing part 36, axially pushing unit 48 is formed among each holding unit 6A and the 6B, and continues to promote main roller 11 along tire axial inside (towards the direction of core 2).
In addition, shown in Figure 10 (c), radial push unit 49 is formed among each holding unit 6A and the 6B, directly makes progress at tire by cylinder portion 16 and inside pushes along tire radial push main roller 11.Axial pushing unit 48 like this and radial push unit 49 constitute thrust unit 50.When casingply sheet Cp was attached to the outer surface of core 2 as described later, thrust unit 50 absorbed the out-of-flatness on the inboard surperficial M1 of formation of tyre surface among Fig. 1, the inboard surperficial M2 of formation of sidewall sections and the inboard surperficial M3 of formation of bead portion.
The operation of the building mortion 1 in the present embodiment below will be described.
Shown in Figure 11 (a), under main roller 11 and auxiliary wheel 12 state that roughly tire of edge wheel is axially arranged shoulder to shoulder as mentioned above, each holding unit 6A and 6B keep casingply sheet Cp.At this moment, because of the external diameter of auxiliary wheel 12 external diameter less than main roller 11, auxiliary wheel 12 upwards is in the inboard of main roller 11 in the footpath of tire, thereby is prevented from interfering with core 2.
By mobile device 7 move radially device 57, a pair of holding unit 6A and 6B can radially move inward along tire, thus the extending part 62 that casingply sheet Cp is extended between main roller 11 can contact with the outer surface of core 2.
In addition, as Figure 11 (a) with (b), when separated from one another, both are moved radially device 57 and are radially shifted to the inboard of core 2 along tire under the effect of the axial moving device 56 of mobile device 7 for a pair of holding unit 6A and 6B.So each main roller 11 can form surperficial M2 along the inboard surperficial M1 of formation of the tyre surface of core 2, sidewall sections inboard in turn along the width of tire and the inboard surperficial M3 of formation of bead portion moves.
Each main roller 11 rolls along the outer surface of core 2 across casingply sheet Cp.At this moment, when each main roller 11 is pressed against casingply sheet Cp on the core 2, the main roller 11 of the first maintaining part 6A is along (arrow D1) smooth and easy rotation clockwise, main roller 11 edge (arrow D2) smooth and easy rotations counterclockwise of the second maintaining part 6B, thus casingply sheet Cp is attached on the core 2.In addition, each auxiliary wheel also is rotated, and the direction of rotation is reverse with corresponding main roller 11.By in clamping casingply sheet Cp, rotating in this way, main roller 11 and auxiliary wheel 12 increase the length of extending part 62 on tire width direction when discharging casingply sheet Cp, thereby casingply sheet Cp efficiently is attached on the outer surface of core 2.In addition, because of the drag effect of detent 47 in the rotation of each auxiliary wheel 12, hinder its rotation (as shown in Figure 6), be suppressed so discharge the problem of casingply sheet Cp and so on fast.
In addition, by thrust unit 50, each main roller 11 can absorb the out-of-flatness that core 2 forms on the surperficial M; Thrust unit 50 comprises axial pushing unit 48 and radial push unit 49.This point is very desirable, make each main roller 11 be able to along the tire width direction uniformity push casingply sheet Cp.
Shown in Figure 12 (a), when each main roller 11 arrived at the surperficial M3 of the inboard formation of bead portion, the attached subsides of a slice casingply sheet Cp were accomplished.Shown in Figure 12 (b), axial moving device 56 and move radially device 57 along tire axial with described a pair of holding unit 6A and 6B outer side shifting to core 2, along tire radially with holding unit 6A and 6B outer side shifting (making progress) to core 2, thereby holding unit 6A is separated with core 2 with 6B.
Next, as described in Figure 13, core 2 rotates predetermined angularpitch (angular pitch) θ P under core tumbler 3 driving of (as shown in Figure 1).In the present embodiment, angularpitch θ P is the central angles of core 2 upper edge tire circumferential directions two casingply sheet Cp adjacent one another are around the L shaped one-tenth of central axis C of back shaft 8.For example, if the number of the casingply sheet Cp that will be attached is set at N, then angularpitch θ P is set to the 360/N degree, thereby can optionally be set within 0～360 degree scope.
Then, similar with above-mentioned situation, a slice casingply sheet Cp is attached, and adjoins the last casingply sheet that is attached.By repeating said process, forming device 1 is being attached to multi-disc casingply sheet Cp on the outer surface of core 2 on the tire circumferential direction continuously, thereby forms casingply.
Such forming device 1 in the present embodiment can be attached to casingply sheet Cp the outer surface of core 2, simultaneously in the length that increases the extending part 62 of casingply sheet Cp between main roller 11 on the tire width direction.Therefore, forming device 1 can highly precisely be attached to casingply sheet Cp on the core 2, to manual operations and similar.
In addition, because forming device 1 comprises core tumbler 3, the latter can make core 2 turn over predetermined angularpitch θ P along tire circumferential direction, thereby forming device 1 can be attached to casingply sheet Cp on the core 2 in turn, and needn't move described a pair of holding unit 6A and 6B along the circumferencial direction of tire.Therefore, this can suppress the increase of forming device 1 size, can boost productivity simultaneously.
In addition, because of each main roller 11 can absorb out-of-flatness on the inboard surperficial M1 of formation of tyre surface, the inboard surperficial M2 of formation of sidewall sections and the inboard surperficial M3 of formation of bead portion, so casingply sheet Cp can be by highly accurately and the attaching of uniformity ground.
And, to compare with the situation of the fast driving parts that use cylinder and so on, mobile device 7 is watched servomotor 73 and 61 mobile each main roller 11 by driving first, second, thereby casingply sheet Cp can be attached by cardinal principle constant speed ground.Therefore, forming device 1 can attach casingply sheet Cp with higher accuracy on width.In this case, in mobile device 7, the mobile control that preferably can be controlled device (not shown) or similar device of each main roller 11 on core 2 upper edge tire width directions.
As shown in figure 14, each main roller 11 is represented with S (mm/second) along the translational speed of outer surface on tire width direction of core 2; On the motion track U of the axis of main roller 11 11c, the distance between optional 2 R1 and the R2 on tire axial is represented with X (millimeter); The distance that directly makes progress at tire between 2 R1 that should be optional and the R2 is represented with Y (millimeter).In this case, the mobile device 7 traveling time Tn (second) that moves main roller 11 preferably satisfies following relational expression:
By making mobile device 7 move main roller 11 according to above-mentioned traveling time Tn, casingply sheet Cp just can with the speed of constant by uniformity attach on the core 2, thereby can form casingply C with higher accuracy.
Figure 15 (a) has schematically showed forming device 1 among another embodiment to 15 (c).Shown in Figure 15 (a), attached label apparatus 4 comprises the first attached label apparatus 4A and along the circumferencial direction and the first attached label apparatus 4A isolated second attached label apparatus 4B of core 2.Such forming device 1 can attach two casingply sheet Cp simultaneously, thereby can boost productivity.
In addition, in the forming device 1 in the present embodiment, core tumbler 3 (as shown in Figure 1) can make core 2 turn to the second attached label apparatus 4B along its circumferencial direction from the first attached label apparatus 4A.In addition, core tumbler 3 is preferably by using pivoting controller 3C (as shown in Figure 1) optionally to repeat attached subsides step and mobile step.In attached subsides step, core 2 turns over an angularpitch θ P at interval according to regular time at every turn; In mobile step, attached label apparatus 4A and 4B are moved into the preposition place when attached subsides step finishes.
In attached subsides step, as Figure 15 (a) with (b), core 2 rotates with angularpitch θ P continuously, is in initial position, casingply sheet Cp1 place by the attached subsides of the first attached label apparatus 4A until the second attached label apparatus 4B.
In addition, in mobile step, as Figure 15 (b) with (c), the rotation of core 2 makes the second attached label apparatus 4B face next attached subsides position PL1 of casingply sheet Cp2, and described casingply sheet Cp2 is the casingply sheet of first attached label apparatus 4A last attached subsides in attached subsides step.
As mentioned above, by alternately repeating attached subsides step and mobile step, forming device 1 is attached to the outer surface of core 2 with casingply sheet Cp, thus high accuracy, high efficiency attaching casingply sheet Cp.
Angle theta 1 between the first attached label apparatus 4A and the second attached label apparatus 4B can be set by suitable.Yet if angle theta 1 is too little, long mobile step consuming time need be performed repeatedly, thereby might cause casingply sheet Cp efficiently not attached.On the other hand, if fruit angle theta 1 is too big, then might cause the increase on forming device 1 size.In view of this, the angle theta 1 between the first attached label apparatus 4A and the second attached label apparatus 4B is preferably greater than and equals 30 degree, more preferably greater than equaling 60 degree.In addition, angle theta 1 is more preferably smaller or equal to 60 degree preferably smaller or equal to 90 degree.
Although more than described specific preferred embodiment of the present invention, the present invention is not limited to the specific embodiment shown in the figure.For implementing the present invention, various changes can be implemented.For example, 3 or more attached label apparatus 4 can be set.
