As shown in Figure 6, main roller 11 is pivotally supported on the first axle 25 by bearing 44.Therefore, main roller 11 is made it can rotate around the axis of the tangent line along tire circumferential direction by the mode supported.In addition, the one-way clutch (one-way clutch) 35 only allowing to rotate along a direction is provided with in main roller 11.Specifically, in fig. 2, the main roller 11 of the first holding unit 6A only can be made (as shown in arrow D1) clockwise and rotate, and the main roller 11 of the second holding unit 6B only can be made (as shown in arrow D2) counterclockwise and rotate.In addition, exemplarily, the outer surface of main roller 11 is provided with anti-slip rubber or similar material (not shown).
In addition, cam part 27 is arranged on one end relative with the place end of main roller 11 on the first axle 25, thus can rotate around the axis identical with the axis of main roller 11.In a top view, cam part 27 is formed as being roughly rectangle.
Cam part 27 by bearing 28 pivotally support by the first axle 25, bearing 28 is different from the bearing 44 of main roller 11.Therefore, cam part 27 and main roller 11 can independently rotate separately.
In addition, as illustrated in Figures 5 and 6, the cam part 27 in the present embodiment is provided with the first projection bar 31, guidance part 32, moving part 33 and the second axle 34.Wherein, the first projection bar 31 is fixed on the outer surface of cam part 27, outwardly gives prominence to from this; Guidance part 32 is fixed on the outer surface of cam part 27, extends perpendicular to the first projection bar 31; Moving part 33 slides along the length direction of guide part 32; Second axle 34 is fixed on moving part 33, is parallel to the first axle 25 and extends, and supports auxiliary wheel 12 rotationally.
Guide part 32 is fixed in cam part 27, and in front view, guide part 32 and cam part 27 cooperation are formed as L shape.In addition, as shown in Figure 6, fall arrest parts 37 are arranged on one end of guide part 32, and extend perpendicular to the length direction of guide part 32, fall for preventing moving part 33.
Second projection bar 38 is arranged on moving part 33, is roughly parallel to the first projection bar 31 and extends.Second pushing part 43, exemplarily, is made up of extension spring, this extension spring hooking and between the second projection bar 38 and the first projection bar 31 extend.Therefore, moving part 33 to be promoted by towards main roller 11 further towards cam part 27.
It is less than main roller 11 that the auxiliary wheel 12 of the present embodiment is formed as external diameter, and by bearing 46 pivotally support by the second axle 34.Because the second axle 34 and the first axle 25 extend parallel to each other, so auxiliary wheel 12 and both main rollers 11 all rotate around the axis of the tangent line along tire circumferential direction.In addition, braking parts 47 is arranged on auxiliary wheel 12, for imposing resistance to resist the rotation of auxiliary wheel 12.
Braking parts 47 comprises: frictional disk 47a, spring 47b and holding tray 47c.Wherein, frictional disk 47a contacts with the side surface of auxiliary wheel 12, imposes resistance to the rotation of auxiliary wheel 12; Frictional disk 47a is pressed to auxiliary wheel 12 by spring 47b; Holding tray 47c is used for keep-spring 47b.
In addition, actuator 13 is arranged between arm 29 and moving part 33 in a hanging manner.Exemplarily, actuator 13 is formed by cylinder, cylinder comprise tubulose cylinder barrel 51 and by feed the pressure-air of cylinder body 51 effect under the bar portion 52 of stretching out from cylinder body 51.The end that actuator 13 is positioned at side, cylinder body 51 place at it is pivotally fixed on by pin 54 exemplarily, and for example, the outer end place of arm 29, the end being positioned at side, place, bar portion 52 at it is fixed on moving part 33.
The operation of each holding unit 6A and 6B will be described herein.In each holding unit 6A and 6B, as shown in Fig. 7 a and 8a, at main roller 11 and auxiliary wheel 12 along the axial side by side arrangement of tire and under the state kept in touch each other, when there being pressure-air to be fed in the cylinder barrel 51 of actuator 13, bar portion 52 stretches out.
As shown in Fig. 7 (b) He 8 (b), by stretching out of bar portion 52, moving part 33 overcomes the motive force of the second pushing part 43, slides and be 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 straight.Now, the direction that main roller 11 can be pressed down at auxiliary wheel 12 is rotated, that is: with regard to the first holding unit 6A, the rotation direction of main roller 11 is the clockwise direction (arrow D1) in figure; With regard to the second holding unit 6B, the rotation direction of main roller 11 is the counter clockwise direction in figure.Therefore, even if impose resistance by braking parts 47 pairs of auxiliary wheels 12, main roller 11 still can rotate.As a result, do not have significant frictional force between main roller 11 and auxiliary wheel 12 and occur, thus auxiliary wheel 12 can be depressed.
As shown in Fig. 7 (c) He 8 (c), along with bar portion 52 continue stretch out, auxiliary wheel 12 is inwardly pressed down together along with moving part 33 in tire radial direction, and separates certain gap with main roller 11 in tire radial direction.Then, carcass ply synusia Cp is arranged in the gap between main roller 11 and auxiliary wheel 12.
In addition, in each holding unit 6A and 6B, when the pressure-air in the cylinder barrel 51 of actuator 13 is released, bar portion 52 is retracted in cylinder barrel 51.Therefore, under the effect of the second pushing part 43, moving part 33 is promoted along guide part 32, thus can at the square upward sliding towards cam part 27.
Therebetween, as shown in Fig. 9 (a), auxiliary wheel 12 is promoted together with moving part 33, thus levels off to main roller 11.Thus, in each holding unit 6A and 6B, main roller 11 and the body piles Cp outer surface Cpo in tire radial direction contacts, and auxiliary wheel 12 contacts with the inner surface Cpi of carcass ply synusia Cp in tire radial direction, thus clamps carcass ply synusia Cp (see Fig. 1).
In addition, as shown in Fig. 9 (b), by one-way clutch 35 (as shown in Figure 6), main roller 11 is prohibited to be rotated along auxiliary wheel 12 by the direction promoted, that is: with regard to the first holding unit 6A, main roller 11 in the drawings counterclockwise on rotation be prohibited; With regard to the second holding unit 6B, main roller 12 in the drawings clockwise on rotation be prohibited.And, because braking parts 47 applies the rotation (as shown in Figure 6) of resistance to auxiliary wheel 12, between auxiliary wheel 12 and main roller 11, produce significant frictional force.So, across carcass ply synusia Cp while the excircle of main roller 11 slowly rotates, auxiliary wheel 12 is promoted to itself and main roller 12 along position during tire axial side by side arrangement.Auxiliary wheel 12 is a kind of desirable situations along the slow lifting of main roller 11, because can prevent carcass ply synusia Cp from offseting because of the position (holding position) being caused it to be kept by involving fast like this, also can prevent because of carcass ply synusia Cp surprisingly pulled the generation of fold that causes.Notably, the setting of braking parts 47 is optionally, and braking parts 47 can be omitted.
Figure 10 (a) and the state of (b) display when there being the pressure F being greater than the first pushing part 36 motive force to act on main roller 11.In this case, while renitency F, main roller 11 can with to move axially together with portion 10 guide by cam part 27, and along tire axial outwards movement.
When pressure F is less than the motive force of the first pushing part 36, main roller 11 moves inward along tire axial with moving axially together with portion 10.By the first such pushing part 36, axial pushing unit 48 is formed in each holding unit 6A and 6B, and continues to promote main roller 11 along tire axial inside (direction towards core 2).
In addition, as shown in Figure 10 (c), radial push unit 49 is formed in each holding unit 6A and 6B, and the pressing inside in tire radial direction by cylinder portion 16 comes along tire radial push main roller 11.Axial pushing unit 48 like this and radial push unit 49 form thrust unit 50.When carcass ply synusia Cp is attached to the outer surface of core 2 as described later, thrust unit 50 absorbs in Fig. 1 the out-of-flatness being formed inside tyre surface and to be formed inside surperficial M1, sidewall sections and to be formed inside surperficial M2 and bead portion on surperficial M3.
Below by the operation of the building mortion 1 in description the present embodiment.
As shown in Figure 11 (a), at main roller 11 and auxiliary wheel 12 as mentioned above roughly along under the state of the axial side by side arrangement of tire of wheel, each holding unit 6A and 6B keeps carcass ply synusia Cp.Now, the external diameter because of auxiliary wheel 12 is less than the external diameter of main roller 11, and auxiliary wheel 12 is in the inner side of main roller 11 in the radial direction of tire, is thus prevented from interfering with core 2.
By the radial-movement devices 57 of mobile device 7, a pair holding unit 6A and 6B radially-inwardly can move along tire, thus the extending part 62 that carcass ply synusia Cp is extended between main roller 11 can with the exterior surface of core 2.
In addition, as shown in Figure 11 (a) He (b), when a pair holding unit 6A and 6B is separated from one another under the effect of the axial moving device 56 of mobile device 7, both are shifted to the inner side of core 2 along tire radial direction by radial-movement devices 57.So each main roller 11 can be formed in turn to be formed inside surperficial M1, sidewall sections along the width of tire and form surperficial M3 inside surperficial M2 and bead portion and move inside the tyre surface of core 2.
Each main roller 11 rolls along the outer surface of core 2 across carcass ply synusia Cp.Now, while carcass ply synusia Cp is pressed against on core 2 by each main roller 11, the main roller 11 of the first maintaining part 6A is along (arrow D1) smooth and easy rotation clockwise, carcass ply synusia Cp along (arrow D2) smooth and easy rotation counterclockwise, thus is attached on core 2 by the main roller 11 of the second maintaining part 6B.In addition, each auxiliary wheel also rotates, and direction and the corresponding main roller 11 of rotation are reverse.By rotating while clamping carcass ply synusia Cp in this way, main roller 11 and auxiliary wheel 12 increase the length of extending part 62 on tire width direction while release carcass ply synusia Cp, thus are efficiently attached on the outer surface of core 2 by carcass ply synusia Cp.In addition, because the drag effect of braking parts 47 is in the rotation of each auxiliary wheel 12, it is hindered to rotate (as shown in Figure 6), so the problem of release carcass ply synusia Cp and so on is able to suppressed fast.
In addition, by thrust unit 50, each main roller 11 can absorb core 2 and form out-of-flatness on surperficial M; Thrust unit 50 comprises axial pushing unit 48 and radial push unit 49.This point is very desirable, makes each main roller 11 be able to press carcass ply synusia Cp along tire width direction uniformity.
As shown in Figure 12 (a), when each main roller 11 arrive to form surperficial M3 inside bead portion time, affixed being accomplished of a slice carcass ply synusia Cp.As shown in Figure 12 (b), described a pair holding unit 6A and 6B moves to the outside of core 2 along tire axial by axial moving device 56 and radial-movement devices 57, along tire radial direction, holding unit 6A and 6B is moved (upwards) to the outside of core 2, thus holding unit 6A with 6B is separated with core 2.
Next, as described in Figure 13, core 2 rotates predetermined angularpitch (angular pitch) θ P under the driving of core tumbler 3 (as shown in Figure 1).In the present embodiment, angularpitch θ P is along the central angle that tire circumferential direction two panels carcass ply synusia Cp adjacent one another are is formed around the central axis CL of back shaft 8 on core 2.For example, if be set as N by by the number of carcass ply synusia Cp attached, then angularpitch θ P is set to 360/N degree, thus can optionally be set within 0 ~ 360 degree of scope.
Then, similar with above-mentioned situation, a slice carcass ply synusia Cp is attached, and adjoins last by the carcass ply synusia attached.By repeating said process, multi-disc carcass ply synusia Cp is attached to continuously on the outer surface of core 2 by forming device 1 on tire circumferential direction, thus forms casingply.
Forming device 1 such in the present embodiment, can be attached to the outer surface of core 2 by carcass ply synusia Cp, increase the length of the extending part 62 of carcass ply synusia Cp between main roller 11 on tire width direction simultaneously.Therefore, carcass ply synusia Cp can highly precisely be attached on core 2 by forming device 1, to hand-manipulated 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, thus carcass ply synusia Cp can be sequentially attached on core 2 by forming device 1, and described a pair holding unit 6A and 6B need not be moved along the circumferencial direction of tire.Therefore, this can suppress the increase of forming device 1 size, can boost productivity simultaneously.
In addition, because each main roller 11 can absorb the out-of-flatness being formed inside tyre surface and to be formed inside surperficial M1, sidewall sections and to be formed inside surperficial M2 and bead portion on surperficial M3, thus carcass ply synusia Cp can by highly accurately and uniformity attach.
And compared with the situation of the fast driving parts of use cylinder and so on, mobile device 7 moves each main roller 11 by driving first, second to watch servomotor 73 and 61, thus enables carcass ply synusia Cp be attached by cardinal principle constant speed.Therefore, forming device 1 can attach carcass ply synusia Cp with higher accuracy in the direction of the width.In this case, in mobile device 7, each main roller 11 preferably can be controlled the control of device (not shown) or similar device on core 2 along the movement on tire width direction.
As shown in figure 14, each main roller 11 represents along the translational speed of outer surface on tire width direction of core 2 with S (mm/second); On the motion track U of the axis 11c of main roller 11, the distance between 2 optional R1 and R2 on tire axial represents with X (millimeter); Distance between these 2 optional R1 and R2 in tire radial direction represents with Y (millimeter).In this case, the traveling time Tn (second) that mobile device 7 moves main roller 11 preferably meets following relational expression:
By making mobile device 7 move main roller 11 according to above-mentioned traveling time Tn, carcass ply synusia Cp just can be attached on core 2 by uniformity with the speed of constant, thus can form casingply C with higher accuracy.
Figure 15 (a) schematically illustrates the forming device 1 in another embodiment to 15 (c).As shown in Figure 15 (a), affixed device 4 comprises the first affixed device 4A and along the circumferencial direction of core 2 and the isolated second affixed device 4B of the first affixed device 4A.Such forming device 1 can attach two carcass ply synusia Cp simultaneously, thus can boost productivity.
In addition, in forming device 1 in the present embodiment, core tumbler 3 (as shown in Figure 1) can make core 2 turn to the second affixed device 4B along its circumferencial direction from the first affixed device 4A.In addition, core tumbler 3 optionally repeats affixing step and mobile step preferably by use pivoting controller 3C (as shown in Figure 1).In affixing step, core 2 turns over an angularpitch θ P according to fixed time interval at every turn; In mobile step, affixed device 4A and 4B is moved into preposition place at the end of affixing step.
In affixing step, as shown in Figure 15 (a) He (b), core 2 rotates with angularpitch θ P continuously, until the second affixed device 4B is in carcass ply synusia Cp1 position affixed by the first affixed device 4A at first.
In addition, in mobile step, as shown in Figure 15 (b) He (c), the rotation of core 2 makes the second affixed device 4B in the face of next affixed position PL1 of carcass ply synusia Cp2, and described carcass ply synusia Cp2 is the first affixed device 4A last affixed carcass ply synusia in affixing step.
As mentioned above, by alternately repeating affixing step and mobile step, carcass ply synusia Cp is attached to the outer surface of core 2 by forming device 1, thus high accuracy, high efficiency attaching carcass ply synusia Cp.
Angle theta 1 between first affixed device 4A and the second affixed device 4B can by suitable setting.But if angle theta 1 is too little, longer mobile step consuming time then needs to be performed repeatedly, thus likely causes carcass ply synusia Cp efficiently not attached.On the other hand, if fruit angle theta 1 is too large, then the increase in forming device 1 size is likely caused.In view of this, the angle theta 1 between the first affixed device 4A and the second affixed device 4B is preferably greater than or equal to 30 degree, more preferably greater than equaling 60 degree.In addition, angle theta 1 is preferably less than or equal to 90 degree, is more preferably and is less than or equal to 60 degree.
Although the foregoing describe the specific preferred embodiment of the present invention, the present invention is not limited to the specific embodiment shown in figure.For implementing the present invention, various change can be implemented.Such as, 3 or more affixed device 4 can be set.
