Description

Post-curing inflator and tire curing cooling means

Technical field

The present invention relates to a kind of expansion cooling tire curing post-curing inflator (post cure inflator) and make the cooling means of vulcanized tyre expansion cooling.

Background technology

Generally speaking, the carcass parts as the inside tires fortifying fibre often use organic fibers such as polyester, nylon or staple fibre.After sulfuration finishes; This fortifying fibre can shrink in the cooling procedure of tire; Because factors such as the inequality of parts and configuration, completed state cause amount of contraction unbalanced; Only make it under laying state, carry out nature cooling, the difference of this amount of contraction can cause distortion, the substandard products of tire appearance, or influence the harmony (uniformity performance) of tire.

Therefore; Usually after sulfidization molding finishes; In tire, enclose air, in the state that maintains its normal shape; In post-curing inflator, be cooled to (be generally below 100 ℃, be preferably below 80 ℃) (for example patent documentation 1 (jp patent publication spy opens flat 6-143298 number)) below the set point of temperature of contraction convergence of fortifying fibre.

This post-curing inflator of developing in the past and using is that two platform position, clamping tires that carry out the tire cool processing make its upset to move two treatment bench positions, so-called two point form post-curing inflator (for example patent documentation 2 (jp patent publication spy opens flat 11-320564 number)) about being provided with.

But in recent years,, occurred shortening the requirement of tire cool time, so begin to develop and use the post-curing inflator that satisfies the time requirement of shortening tire cool in every respect along with the shortening of cure time.For example; In patent documentation 3 (jp patent publication spy opens 2002-307444 number); Passage in the in-house formation hollow of wheel rim at the tire frame position of clamping tire has been proposed; In this hollow channel, charge into the cooling air and make it mobile, spray air or water smoke in the outside of tire simultaneously, to force to accomplish at short notice the post-curing inflator of tire cool.

But there is vulcanized tyre long problem cool time in the post-curing inflator in the patent documentation 1.But also exist following problem; For example receive the influence of free convection, tire curing upper temp is often too high, when the equipment environment temperature is asymmetric; The temperature towards vulcanizer one side is also often too high in the vulcanized tyre; In addition, cause the tire environment temperature difference to occur because aspects such as the type of tire, structure, material are asymmetric, vulcanized tyre can't obtain balanced cooling on above-below direction or circumferencial direction; Under the influence of the temperature difference that this inhomogeneous cooling causes, fluctuation can appear in tapering quality aspects such as (conicity).

In addition, when using the post-curing inflator in the patent documentation 2, be difficult to realize the equilibrium cooling of tire whole outer surface, thus on tire circumferential direction appearance temperature deviation or cooling deviation.In addition, have also that device structure is complicated, with high costs, problems such as the frequency safeguarded and expense height.

For cooling medium such as the use in the patent documentation 3 cooling air or water smokes tire is forced the post-curing inflator that cools off, stains such as water spots often appear in the position that cooling medium such as water are sprayed onto, thereby the tire outward appearance is caused bad influence.In addition; Because need be in mechanisms such as drive source that supply cooling medium are set on every side that installs and pipe arrangements; This type of peripheral equipment will cause maximization and structure complicated of equipment; Simultaneously, the use of peripheral equipment will cause the raising of component costs, and the running of drive source will cause the significantly rising of operating cost.

Summary of the invention

The present invention makes in view of above-mentioned technical problem in the past just, maximization that its purpose is to provide the quality of a kind of cooling that can be at short notice vulcanized tyre be fit to improve tire, can not cause equipping and structure complicated and the post-curing inflator that significantly rises that can not cause component costs and operating cost.

For addressing the above problem, post-curing inflator provided by the present invention comprises: the tire curing vulcanized tyre of clamping clamping device; With the rotary drive mechanism that said vulcanized tyre is rotated.

In addition, each rotation is handled and loaded on the rear side central frame 112A that machine 104 is arranged on vulcanizer frame 112.Each rotation is handled and loaded the rotary middle spindle of machine 104 and is led platform 134 (support portion) on to be arranged on along what the guide rail 133 of rear side central frame 112A setting went up and down with rotating freely, and each rotation is handled and loaded machine 104 and all had turning arm 104A and tire anchor clamps 104B.Turning arm 104A is installed in to lead on the platform 134 and also can it rotates freely for axle, through not shown a plurality of hydraulic pressure or pneumatic cylinder tire anchor clamps 104B is rotated between vulcanizer 102 and post-curing inflator 101.Tire anchor clamps 104B has the jaw 104a more than 3 that can on the radiation direction, open simultaneously or shrink equally spaced to be set up on its circumferencial direction; Make it to open after can each jaw 104a being inserted into vulcanized tyre 1 or having cooled off in the tire 1 ' under contraction state and grasp tire frame position, and can each jaw 104a be shunk once more and decontrol each tire 1,1 '.

Be provided with among the rotary motion trace a of above-mentioned each turning arm 104A and discharge conveyer belt 105.Discharging conveyer belt 105 is the roller bearing type conveyer belts that are made up of a plurality of roller bearings, is positioned at the below that machine 104 is handled and loaded in rotation, and near the position in expansion cooling end 103 outsides, be arranged on the fore-and-aft direction with cooling end 103 with arranging.Each discharges conveyer belt 105, and in order not influence the up-down of lower rim mechanism 2, also can guarantee to have cooled off tire from vulcanizer 102 1 side direction carrying conveyer belt 106 lopsidedness ground can be configured to carrying conveyer belt 106 ground in own wt effect lower slider.Carrying conveyer belt 106 is belt conveyors, is arranged on the rear of post-curing inflator 101 at a distance from certain intervals, and will be transported to tyre inspection operation or finished product storehouse as later process from the tire of cooling 1 ' that release conveyer belt 105 sends.

As shown in Figure 3, the cooling end 103 that respectively expands in the post-curing inflator 101 comprises: the clamping device of vulcanized tyre 2 of horizontally disposed 1 downside of vulcanized tyre of clamping (below be called lower rim mechanism 2); With the clamping device of vulcanized tyre 3 of 1 upper side of clamping vulcanized tyre (below be called wheel rim mechanism 3).Last wheel rim mechanism 3 comprises: under airtight conditions clamping vulcanized tyre 1 on tire frame position 1a on wheel rim 4; And the last wheel rim attaching parts 5 that link to each other with last wheel rim 4.In addition, vulcanized tyre 1 is the shape that benchmark forms symmetry with the central point on the direction of principal axis, and center, tire curing equator is defined as the line that the central point that passes on the direction of principal axis and vertical with it plane and vulcanized tyre 1 tyre surface intersect.

Above-mentioned upward wheel rim 4 is formed into to have and the corresponding external diameter disc of the diameter of the last tire frame 1a of portion.The peristome 4a that the fixed axis 33 that the inner ring side of last wheel rim 4 is stated after being provided with and can letting passes.The upper fixed of last wheel rim 4 has last wheel rim attaching parts 5.Last wheel rim attaching parts 5 are made into cylindrical shape to surround peristome 4a, and the central shaft on its central shaft and last wheel rim 4 vertical directions is overlapping.

The last wheel rim mechanism 3 that as above constitutes can rotate with any direction and rotating speed under rotary drive mechanism 10 effects.Rotary drive mechanism 10 comprises: be horizontally fixed on the follow-up pulley 11 on the rotary drive mechanism 10 outer ring faces; Be arranged on the drive pulley 12 of follow-up pulley 11 sides; The driving belt 13 that connects follow-up pulley 11 and drive pulley 12; And the tire CD-ROM drive motor 14 that links to each other with drive pulley 12.And rotary drive mechanism 10 can through drive pulley 12 with drive belt 13 rotary driving force is delivered to follow-up pulley 11, wheel rim attaching parts 5 and last wheel rim 4 rotations drivings in drive 1 high speed of vulcanized tyre that is bearing on the wheel rim 4 and rotate.

For example shown in Fig. 9, " rotation at a high speed " here is meant at this and forms this part the influence of air-flow greater than the rotary speed of the forced convertion of free convection periphery of vulcanized tyre 1.Particularly, be velocity of rotation when making vulcanized tyre 1 with the above rotating speed rotation of 100rpm (inferior/minute).Say that again the velocity of rotation of " rotation at a high speed " gets final product, but is preferably more than the 200rpm, more preferably more than the 300rpm, is preferably in addition below the 1000rpm, more preferably below the 800rpm more than 100rpm.The reason of capping is here; Rotating speed is continued to improve in the back even acquire a certain degree; Cooling effect (required cool time) is no change almost but, can cause the durability of equipment significantly to reduce on the contrary, and the cost of equipment and the labour that need overspending simultaneously are to guarantee security.Say that again when being equipped with fin, the effect when then it rotate with the rotating speed below the 500rpm is suitable with the effect when rotating with 800～1000rpm when not being equipped with.

So; Rotary drive mechanism 10 is to form the forced convertion of influence greater than free convection in the periphery of vulcanized tyre 1 at this; Come to rotate at a high speed vulcanized tyre 1; Can forced convertion take away the heat in the vulcanized tyre 1 energetically, thereby can at short notice it be cooled to below certain temperature.In addition, be to be the monosymmetric air-flow on direction of principal axis of benchmark through producing above-mentioned forced convertion with the center, equator of vulcanized tyre 1, can cool off vulcanized tyre 1 on the ground of the bilateral symmetry on the direction of principal axis that with the center, equator is benchmark.So can improve expand cooled quality, particularly uniformity.In other words; Post-curing inflator; So that the center, equator of vulcanized tyre 1 is the physics value that both sides on the direction of principal axis of benchmark demonstrate symmetry; Come to rotate at a high speed vulcanized tyre 1, thereby form the forced convertion of influence, simultaneously to the cooling of expanding of vulcanized tyre 1 greater than free convection in the periphery of vulcanized tyre 1." physics value " in the specification is meant the property value of at least one physical property factor from the physical property factors such as middle dilatability of hardness, hot strength, ductility, gum intensity, bounce-back property, tension resistance to spalling, compression set, mar proof, the bent cracking of folding, casing ply (carcasscord), might not refer to the property value of property sexual factor.

As shown in Figure 3, the above-mentioned inner ring side that goes up the last wheel rim attaching parts 5 in the wheel rim mechanism 3 is disposed with: with the last wheel rim supporting mechanism 21 of wheel rim mechanism 3 on the free rotation ground supporting; Releasably to connect the locking mechanism 31 of going up wheel rim mechanism 3 and lower rim mechanism 2.Last wheel rim supporting mechanism 21 comprises: along the cylindrical shape tubular support component 22 of last wheel rim attaching parts 5 inner ring faces setting; And be arranged on the parts of bearings 23 between tubular support component 22 and the last wheel rim attaching parts 5.The upper end of tubular support component 22 is fixedly installed on the horizontal frame 6.In addition, horizontal frame 6 constitutes the part of the not shown frame structure that keeps the post-curing inflator posture.On the other hand, parts of bearings 23 is to be permanently connected tubular support component 22 and last wheel rim attaching parts 5, with free rotation ground supporting in the horizontal direction simultaneously on above-below direction.So, last wheel rim supporting mechanism 21 on the certain altitude position of horizontal frame 6 regulation with free rotation ground supporting on wheel rim mechanism 3.

The above-mentioned inner ring side that goes up wheel rim supporting mechanism 21 is provided with locking mechanism 31.Locking mechanism 31 comprises that Lock Part 32, lock shaft 33 and locking are with rotating mechanism 34.Lock Part 32 is with in the tubular support component 22 that is entrenched in wheel rim supporting mechanism 21 freely to rotate.In addition, the front end position of turning cylinder 35 links to each other with the upper portion of Lock Part 32 free to rotately.Turning cylinder 35 is horizontally disposed with, and its rear portion links to each other with cylinder device such as hydraulic cylinder or pneumatic cylinder 36.Turning cylinder 35 constitutes locking with rotating mechanism 34 with cylinder device 36, and locking makes turning cylinder 35 rotations with rotating mechanism 34 through cylinder device 36, thereby makes the Lock Part 32 can be in forward or backwards rotation.

The depressed part 32a that the Lock Part 32 that above-mentioned locking is rotated with rotating mechanism 34 has lower opening.The top centre of depressed part 32a is provided with pore 32d, and pore 32d in the vertical direction runs through the upper wall portions of Lock Part 32, and its other end links to each other with air hose 7.The feeder that does not show among air hose 7 and the figure links to each other.Feeder comprises: supply is expanded with air so that the vulcanized tyre 1 pressure effect gas supply assembly of expansion down in vulcanized tyre 1; Expand with the air mechanism of taking a breath with replacement under situation such as vulcanized tyre 1 rotation.

In addition, the lower end of depressed part 32a is formed with from sidewall and stretches to the outstanding lock part 32b of inner ring direction on four sides, and is formed with between the adjacent lock part 32b, 32b and inserts thorough cut 32c (notch part).Insert thorough cut 32c and form the protuberance 33a that passes lock shaft 33.Say again; The locking mechanism 31 that as above constitutes; Through locking with rotating mechanism 34 for example when the twist-lock parts 32 to the forward, then can make the protuberance 33a and the slotting thorough cut 32c consistency from top to bottom of lock shaft 33, and the protuberance 33a of lock shaft 33 can freely get into or withdraw from depressed part 32a; On the other hand; For example when toward backwards rotation driven locking parts 32, then can make the protuberance 33a and the lock part 32b consistency from top to bottom of lock shaft 33, and the protuberance 33a of lock shaft 33 is fixed in the depressed part 32a.

The above-mentioned protuberance 33a of above-mentioned lock shaft 33 is set at the four sides of upper end, and it is outstanding to point to the outer ring direction.In addition, lock shaft 33 is configured with the central shaft of its axle center with above-mentioned lower rim mechanism 2 with aliging, has: the axial region 33b that hangs down from the upper end; With the shaft supporting part 33c that forms in axial region 33b lower end.

Lower rim mechanism 2 can be arranged on the above-mentioned shaft supporting part 33c freely to rotate.Lower rim mechanism 2 comprises: under airtight conditions, keep the lower rim 16 of the following tire frame position 1b of vulcanized tyre 1; The lower rim support component 17 that links to each other with lower rim 16; And lower rim support component 17 can be connected with rotating freely the lower rim bindiny mechanism 18 on the shaft supporting part 33c of lock shaft 33.

Above-mentioned lower rim 16 is formed into the disc that has with footpath outside the diameter of the following tire frame 1b of portion is corresponding.The inner ring side of lower rim 16 is provided with the peristome 16a that can let said fixing axle 33 pass.The below of lower rim 16 is fixed with lower rim support component 17.Lower rim support component 17 is made into cylindrical shape to surround peristome 16a, and the central shaft of its central shaft and lower rim 16 is overlapping.In addition, the inner ring side of lower rim supporting mechanism 17 is provided with the lower rim bindiny mechanism 18 that is made up of parts of bearings.The lower rim mechanism 2 that as above constitutes, the following tire frame position 1b through grasping vulcanized tyre 1 and along with the rotation of last wheel rim mechanism 3 is rotated is with respect to lock shaft 33 free rotation ground supportings vulcanized tyre 1.

In addition, the elevating mechanism that does not show among the lower end of lock shaft 33 and the figure links to each other.Elevating mechanism can make tire placement location that lock shaft 33 do not show in the drawings and than free lifting between the higher tire installation site of shown position.Say again, can be at the tire placement location with vulcanized tyre 1 from 2 loading and unloading of lower rim mechanism.On the other hand, in the tire installation site, the last tire frame position 1a of vulcanized tyre 1 is gripped by last wheel rim mechanism 3, and by lower rim mechanism 2 and on carry out cooling processing under the state of wheel rim mechanism 3 clampings.

About above-mentioned cooling processing,, can also get rid of mechanism 41 through air and implement except that rotating the vulcanized tyre 1 through rotary drive mechanism 10.It is the rotations that utilize rotary drive mechanism 10 to produce that air is got rid of mechanism 41, and mandatory eliminating is the tyre sidewall 1c, near the device of the air the 1d of vulcanized tyre 1 side surface part.

That is it is through together rotating with wheel rim mechanism 3,2 that air is got rid of mechanism 41, and formation comprises along the side surface direction composition of vulcanized tyre 1 or the air-flow of radial direction composition.Specifically, air is got rid of mechanism 41 and is separately positioned on wheel rim mechanism 3 and lower rim mechanism 2 places, and is furnished with a plurality of tab member 42 of the driving force of transmitting the rotary drive mechanism generation.As shown in Figure 4, these tab member 42 are with on the circumference that is arranged on each 3,2 outer ring portion of wheel rim mechanism equally spacedly.In addition, tab member 42 is with the crooked plate object of the radius of curvature suitable with each wheel rim mechanism 3,2 outer ring face, and it tilts with respect to the radial direction of each wheel rim mechanism 3,2.That is an end of tab member 42 inner ring sides more is inclined to upper reaches one side of direction of rotation (direction of arrow among the figure) with respect to the other end, promptly forms so-called swept-back wing.Thus; Through the tab member 42 common rotation with each wheel rim mechanism 3,2, air is got rid of mechanism 41 and can under the situation that does not reduce the relative velocity on the circumferencial direction, be formed and comprise the air-flow of outwards dispersing composition along the side surface direction composition of vulcanized tyre 1 or along radial direction.In addition, this air is got rid of the centrifugal fan structure that mechanism 41 also can adopt similar multiple wing centrifugal fan.Say that again tab member 42 not only can be rotated with wheel rim mechanism jointly, also can do relative rotation.

Be provided with the partition member 43 of getting rid of mechanism's 41 parts as air from seen tire 1 opposite one side of tab member 42 directions that are arranged on upside and downside.Partition member 43 is divided into tyre sidewall 1c, the 1d regions of tire 1 that air as tab member 42 flows into the 1st area of space A of a side and near the tyre sidewall 1c of tire 1, the 2nd area of space B of 1d one side.That is partition member 43 is the cylindrical shape thing that connects from top to bottom.The internal diameter that the partition member 43 that is provided with can make tab member 42 sides (side) is littler than opposite side internal diameter near the internal diameter of the top of tab member 42 outer ring sides and this side.Thus, partition member 43 can prevent that the air in the 2nd area of space B from flowing into the 1st area of space A, can concentrate among the 1st area of space A air before the heat exchange simultaneously and make it flow into tab member 42 in large quantities.

In addition, can adopt driving force of decomposing partial rotation driving mechanism 10 and the structure that is transferred to tab member 42, also can adopt the structure that the driving force of the driving mechanism of establishing in addition beyond the rotary drive mechanism 10 is delivered to tab member 42.When rotating relatively, phase place constantly changes on the direction of rotation of tire 1 and tab member 42, thereby can on tire circumferential direction, realize balanced more exhaust effect.In addition, when beyond rotary drive mechanism 10, establishing airfoil parts 42 in addition the driving mechanism of driving force being provided, can the tab member 42 that driven by different driving mechanism be set respectively in the above and below of vulcanized tyre 1.The tab member 42 that also can be merely tire curing top is provided with the driving mechanism of the driving force of sending outside the rotary drive mechanism 10 separately.So can adjust the cooling capacity of the vulcanized tyre 1 of the upper portion that is positioned at vulcanized tyre 1 and following side branch.That is, can carry out more senior adjustment to the upper and lower temperature difference of vulcanized tyre 1.Therefore; For example receive the influence of the asymmetry of equipment peripheral temperature; The temperature of tire curing upper portion is often too high; The perhaps upper portion of vulcanized tyre 1 asymmetric with lower portion (for example the shape of tyre sidewall 1c, 1d is different) and the cooling velocity of also adjustable close side sections and lower portion appears under the situation such as deviation in cooling velocity.The shape of tab member 42 that in addition, also can be through changing tire curing upside and downside or increase and decrease its sheet number individually to adjust the cooling capacity of tire curing upper portion and lower portion.

In addition, be provided with a part of cooling air supply mechanism 44 of getting rid of mechanism 41 as air from seen tire 1 opposite side of partition member 43 directions that are arranged on upside and downside.Cooling air supply mechanism 44 comprises: form and the ring-type pipe arrangement 45 that is configured with the last wheel rim attaching parts 5 of surrounding each wheel rim mechanism 3,2 and lower rim support component 17; The cooling air supply device that in the figure of ring-type pipe arrangement 45 supplied with cooling air, does not show; And be arranged on the ring-type pipe arrangement 45 with airfoil parts 42 and spray the nozzle that does not show among the figure of cooling air.In addition, nozzle also can be the through hole that forms on the ring-type pipe arrangement 45.

Below, the operating condition of the post-curing inflator 101 that as above constitutes is described.

Like Fig. 1 and shown in Figure 2, after vulcanizer 102 was accomplished sulfidization molding, machine 104 up-downs were handled and loaded in each rotation, rotation places tire anchor clamps 104B in each mould 110.Reduce tire anchor clamps 104B then and grasp vulcanized tyre 1.Then, up-down, rotating tire's anchor clamps 104B vulcanized tyre 1 rotate the cooling end 103 that respectively expands that is transported to post-curing inflator 101 from each mould 110.The tire placement location that in the figure that lower rim mechanism 2 is dropped to the lower position, does not show; After vulcanized tyre 1 decline of handling and loading machine 104 along with each rotation has been carried to each lower rim mechanism 2; Machine 104 risings, rotation are handled and loaded in each rotation, leave the cooling end 103 that respectively expands.

As stated, vulcanized tyre 1 is removed to lower rim mechanism 2, and as shown in Figure 3, the following tire frame position 1b of vulcanized tyre 1 is by lower rim 16 clampings of lower rim mechanism 2.Subsequently, lock shaft 33 rises, lower rim mechanism 2 and vulcanized tyre 1 rise thereupon.At this moment, in the locking mechanism 31, Lock Part 32 is forward rotation under locking with the driving of rotating mechanism 34, makes the protuberance 33a of lock shaft 33 and the slotting thorough cut 32c consistency from top to bottom of Lock Part 32.The protuberance 33a of therefore, rising lock shaft 33 passes and inserts in the thorough cut 32c entering depressed part 32a.Then, after lock shaft 33 arrived the tire installation sites as upper limit position, its rising was stopped, and the last tire frame position 1a of vulcanized tyre 1 is by last wheel rim 4 clamping under airtight conditions of last wheel rim mechanism 3.

Subsequently, in the locking mechanism 31, Lock Part 32 backwards rotation, lock part 32b is with respect to the protuberance 33a consistency from top to bottom of lock shaft 33.Gas supply mechanism entry into service in the feeder that does not show among the figure then, air is used in the expansion that in vulcanized tyre 1, charges into regulation air pressure through air hose 7 grades.The result; The protuberance 33a of lock shaft 33 by the lock part 32b in the depressed part 32a after fixing on the above-below direction; The state that wheel rim mechanism 3 and lower rim mechanism 2 are fixed through lock shaft 33 separated by a distancely in the appearance, simultaneously, vulcanized tyre 1 is expanded to the regulation shape and keeps its shape.

Then, the ventilation mechanism in the feeder turns round aptly, and replacement is expanded and used air when keeping in the vulcanized tyre 1 certain pressure.So, discharge on the one hand the expansion of carrying out heating up after the heat exchange with vulcanized tyre 1 and use air, air is used in the expansion of the low temperature before the supply heat exchange in vulcanized tyre 1 on the other hand, thereby can cool off efficiently in the inside realization of vulcanized tyre 1.

In addition, after tire CD-ROM drive motor 14 runnings in the rotary drive mechanism 10, rotate upward wheel rim mechanism 3, drive the vulcanized tyre 1 that is bearing in the wheel rim mechanism 3 and rotate at a high speed through drive pulley 12, driving belt 13 and follow-up pulley 11.So the periphery of vulcanized tyre 1 forms the forced convertion of influence greater than free convection, the heat in the vulcanized tyre 1 is taken away in forced convertion energetically.Thus; With the cooling of under the state that stops, expanding of vulcanized tyre 1; Or mainly receive the influence of free convection and vulcanized tyre 1 is expanded compare under the situation of cooling in rotation, vulcanized tyre 1 can be cooled to below the set point of temperature in the shorter time.

In addition; Vulcanized tyre 1 is the shape that benchmark is symmetry with the central point on the direction of principal axis; Thereby vulcanized tyre 1 at a high speed the forced convertion that produces of rotation be with center, tire curing equator, promptly pass line that central point and vertical with it plane and vulcanized tyre 1 tyre surface on the direction of principal axis intersect and be monosymmetric air-flow on the direction of principal axis of benchmark.So vulcanized tyre 1 has been in the direction of principal axis bilateral symmetry property cooling that with the center, equator is benchmark, thereby improved the cooled quality that expands, particularly harmonious.

In addition; Along with the rotation of vulcanized tyre 1; After each tyre sidewall 1c, 1d moved with respect to ambient air, the surperficial relative velocity that forms tyre sidewall 1c, 1d was zero and distributes promptly so-called speed boundary layer away from the big more air-flow of surperficial relative velocity more; Get rid of under the air-flow effect that mechanism 41 causes at air, this speed boundary layer is thinner during than rotating tire's only.Identical therewith, in the temperature field, thin out near the temperature boundary layer of tyre sidewall.The thin more thermal resistance of this boundary layer is low more, and tyre sidewall 1c, 1d can realize cooling more apace.Vulcanized tyre 1 needs with the fully next rotation at a high speed of speed of attenuation of speed boundary layer, and its rotating speed should be more than the 100rpm, is preferably more than the 200rpm, more preferably more than the 300rpm.Like further raising rotating speed, then can realize cooling at faster speed.

In addition, the tyre sidewall 1c that heats up because of heat exchange, near the air the 1d are got rid of mechanism's 41 mandatory eliminatings by air.That is after having begun to cool down under the rotation of vulcanized tyre 1, the sub-cooled air sprays to tab member 42 from the ring-type pipe arrangement 45 in the cooling air supply mechanism 44.In addition, after each wheel rim mechanism 3,2 rotates, the tab member 42 that sets within it also will be rotated, and promptly on the axle center with each wheel rim mechanism 3,2 is the circumferencial direction at center, rotate.So; Comprise that the air before the heat exchanges such as cooling air in the 1st area of space A of each wheel rim mechanism 3,2 side is pushed into tire 1 direction by tab member 42 from partition member 43, form the tyre sidewall 1c that comprises along vulcanized tyre 1, the air-flow (wind) of 1d direction composition.

Thus, near the high temperature air tyre sidewall 1c, the 1d after the heat exchange is with to leave vulcanized tyre 1, and by the air of tab member 42 before the 1st area of space A supply heat exchange, to replenish the air of discharging in the above described manner.Therefore, the tyre sidewall 1c of vulcanized tyre 1,1d can exist the air of the big temperature difference to carry out heat exchange with it always.Thereby can be cooled at short notice below the fixed temperature.In addition, when being equipped with tab member 42 and not being equipped with, compare, realize equal effect in rotating speed that can be lower or shorter time.

Say that again near the 2nd area of space B the tyre sidewall 1c, 1d is isolated by partition member 43 and the 1st area of space A relatively, therefore, can stop with vulcanized tyre 1 heat exchange after the hot-air of the 2nd area of space B that heats up mobile to the 1st area of space A.So, only there is the preceding air of heat exchange in the 1st area of space A, this air flows into tab member 42, therefore can realize the cooling of tyre sidewall 1c, 1d more efficiently.

In addition, when making as so vulcanized tyre 1 that rotation is with cooling at a high speed, each tyre sidewall 1c of upside and downside, the air of 1d flow along the peripheral direction of vulcanized tyre 1.So can prevent that accomplishing the air that heats up after the heat exchange with the tyre sidewall 1d of downside rises because of free convection and rotate to the appearance of this state of upside tyre sidewall 1c.Therefore, two tyre sidewall 1c of upside and downside, 1d can realize cooling under identical condition.In addition, this rotates at a high speed under the centrifugal action that produces down, and vulcanized tyre 1 inner air will be created in monosymmetric air-flow on the direction of principal axis, thereby can be from symmetry (equilibrium) cooling of both sides on the inside impeller-hub direction of vulcanized tyre 1.So; Have through employing and to make the vulcanized tyre 1 can be with the for example post-curing inflator 101 of the rotary drive mechanism 10 of rotation at a high speed more than the 100rpm; To the having or not of rotating speed, tab member 42,42 of vulcanized tyre 1 and tab member counterrotating have or not or up and down tab member 42 rotating speed separately etc. adjust aptly; Can realize adapting to inside and outside the cooling, tire of tire shape agonic cooling and can adjust or shorten cool time, also can tune to and in a vulcanisation cycle, accomplish cooling.In other words; Post-curing inflator 101 also can possess can be adjusted in a vulcanisation cycle structure and the function of accomplishing cooling, for example to the having or not of rotating speed, tab member 42,42 of vulcanized tyre 1 and tab member counterrotating has or not or the structure and the function of the adjustment that suits such as tab member 42 rotating speed separately up and down.In addition, owing to can realize balanced cooling on above-below direction and the circumferencial direction of vulcanized tyre 1, cooled vulcanized tyre 1 is with regard to the good quality of oblatio.

After as above accomplishing the cooling of vulcanized tyre 1, discharging expands use air, and in locking mechanism 31, Lock Part 32 is forward rotation under locking with the driving of rotating mechanism 34, makes the protuberance 33a of lock shaft 33 and the slotting thorough cut 32c consistency from top to bottom of Lock Part 32.Lock shaft 33 descends subsequently, places the interior protuberance 33a of depressed part 32a to pass slotting thorough cut 32c and withdraws to the outside.Then; After lower rim mechanism 2 together dropped to the tire placement location that does not show among the figure with cooled vulcanized tyre 1 and stops, like Fig. 1 and shown in Figure 2, rotation was handled and loaded machine 104 and is taken out vulcanized tyre 1; Like this, do not produce stand-by time and can begin the next cooling of vulcanized tyre 1.

(embodiment 2)

Below the other embodiment of post-curing inflator is described.

Shown in figure, post-curing inflator comprises: the lower rim mechanism 2 of horizontally disposed 1 downside of vulcanized tyre of clamping; Last wheel rim mechanism 3 with 1 upper side of clamping vulcanized tyre.Last wheel rim mechanism 3 can rotate with any rotating speed down in rotary drive mechanism 74 effects.Rotary drive mechanism 74 comprises: the rotating shaft member 75 that is connected with wheel rim mechanism 3; With free rotary ground supporting rotating shaft member 75 and with the outer cylinder member 76 of rotating shaft member 75 in vertical direction; And pass through pulley or drive the CD-ROM drive motor 77 that belt links to each other with the upper end of rotating shaft member 75.Rotating shaft member 75 is provided with pore 75b, pore 75b up/down perforation, and its other end links to each other with feeder through the air hose that does not show among the figure.

Support the outer cylinder member 76 of above-mentioned rotating shaft member 75, also as shown in Figure 5, be fixedly installed on the horizontal frame 78.The outer ring face side of outer cylinder member 76 disposes rotating mechanism 79.Rotating mechanism 79 comprises: be arranged on cartridge unit 76b the outer ring face, can make joint that bar 80a in the vertical direction advance and retreat move with cylinder barrel 80; Can with engage engage with the bar 80a of cylinder barrel 80, be fixedly installed on the bond pad 81 on the rotating shaft member 75; And by outer cylinder member 76 supporting and make rotation that cartridge unit 76b rotates in the horizontal direction with cylinder barrel 82.

The below of above-mentioned rotating mechanism 79 is provided with locking mechanism 83.Locking mechanism 83 comprises: the protuberance 75a that is formed at the bottom (leading section) of rotating shaft member 75; And the Lock Part 84 that links to each other with last wheel rim mechanism 3.Lock Part 84 is provided with the depressed part 84a of top opening.The upper end of depressed part 84a is provided with from sidewall stretches to the outstanding lock part 84b of inner ring direction on four sides, and is formed with slotting thorough cut (notch part) between the adjacent lock part 84b84b.Slotting thorough cut forms the protuberance 75a that passes rotating shaft member 75.Say again, the locking mechanism 83 that as above constitutes, through rotating mechanism 79 for example when to the forward rotating rotating shaft member 75; Then can make protuberance 75a and slotting thorough cut consistency from top to bottom; And protuberance 75a can freely get into or withdraw from depressed part 84a, on the other hand, and for example when the time toward backwards rotation rotating shaft member 75; Then can make protuberance 75a and lock part 84b consistency from top to bottom, and protuberance 75a is fixed in the depressed part 84a.Other the structure with embodiment 1 in post-curing inflator 101 identical.

Below, the operating condition of the post-curing inflator that as above constitutes is described.

At first, the tire placement location that in the figure that lower rim mechanism 2 is dropped to the lower position, does not show, vulcanized tyre 1 carries in lower rim mechanism 2, and vulcanized tyre 1 is by 2 supportings of lower rim mechanism.Subsequently, lower rim mechanism 2 together rises with locking mechanism 83, lower rim mechanism 2 and vulcanized tyre 1 rise thereupon.At this moment, be positioned at the rotating shaft member 75 of the top of locking mechanism 83, after forward rotation under the driving of rotating mechanism 79, the slotting thorough cut 32c consistency from top to bottom of protuberance 75a and Lock Part 32.Therefore, the protuberance 75a of the Lock Part 84 of rising gets in the depressed part 84a.Then, behind the tire installation site that lower rim mechanism 2 arrives as upper limit position, its rising is stopped, and vulcanized tyre 1 is by the clamping under airtight conditions of last wheel rim mechanism 3.

Subsequently, in the rotating mechanism 79, rotating shaft member 75 is by backwards rotation, and the lock part 84b of Lock Part 84 is with respect to the protuberance 75a consistency from top to bottom of rotating shaft member 75.Then, the gas supply mechanism entry into service in the feeder that does not show among the figure, in vulcanized tyre 1, charge into decide air pressure expansion use air.The result; The protuberance 75a of rotating shaft member 75 by the lock part 84b in the depressed part 84a after fixing on the above-below direction; The lock-out state that wheel rim mechanism 3 and lower rim mechanism 2 are fixed through rotating shaft member 75 separated by a distancely in the appearance; Simultaneously, vulcanized tyre 1 is expanded to institute's shaped and keeps its shape.

Subsequently, the bar 80a that engages with cylinder barrel 80 retreats, and behind the engagement relationship of releasing and bond pad 81, rotating shaft member 75 just can rotate from bent with respect to outer cylinder member 76.Afterwards, running motor 77 makes spindle unit 75 rotations through pulley and belt drives.So vulcanized tyre 1 cooling of under rotation at a high speed, expanding.

Vulcanized tyre 1 is accomplished cooling, discharge to expand with behind the air, in locking mechanism 83 and the rotating mechanism 79, through with the opposite action of action that is connected above-mentioned lower rim mechanism 2 and last wheel rim mechanism 3 state that unlocks.Then, after lower rim mechanism 2 together drops to the tire placement location that does not show among the figure with cooled vulcanized tyre 1 and stops, taking out vulcanized tyre 1, the expansion cooling of the next vulcanized tyre 1 of beginning.Other operation process is identical with post-curing inflator 101 among the embodiment 1.

Below, carry out following simulated test, to confirm the cooling effect of the post-curing inflator in the present embodiment 1,2.

At first investigated flow regime in the past, that when leaving standstill vulcanized tyre 1, produce air-flow around its of (rotating speed 0rpm).Fig. 7 and Fig. 8 are the sketch map of this analog result.Fig. 7 is radial direction and vertical direction speed vector figure, and Fig. 8 is the isopleth map of radial direction speed composition.Among Fig. 8, tone representes that more deeply then speed is big more.Its result such as Fig. 7 and shown in Figure 8 can know that the air that the tyre sidewall 1d portion of the downside of vulcanized tyre 1 of producing in the tire outside heats up rises, and rotate to the air-flow (by the air-flow that free convection forms, the direction of arrow) of the free convection character of upside tyre sidewall 1c.And can know the inboard free convection that produces lifting cord liner (belt inner liner) portion of tire, and the formation temperature layering, temperature difference up and down produced.

Next has investigated that vulcanized tyre 1 is installed in the post-curing inflator that is equipped with tab member 42, and during with 500 times/minute rotating speed rotation vulcanized tyre 1 around produce the flow regime of air-flow.Fig. 9 is the sketch map of this analog result, is radial direction and vertical direction speed vector figure.Its result is as shown in Figure 9; Can know the air-flow (direction of arrow) of the forced convertion character that produces the tyre sidewall 1c comprise along vulcanized tyre 1,1d direction composition; Be monosymmetric air-flow on the direction of principal axis of benchmark with the center, equator of vulcanized tyre 1 promptly, near the air tyre sidewall 1c, the 1d is benchmark bilateral symmetry and eliminating of being forced property on direction of principal axis with the center, equator.

Investigated in addition and contrasted under the situation that is equipped with tab member 42 and is not equipped with, during with 600 times/minute rotating speeds rotation vulcanized tyre 1 around produce the flow regime of air-flow.Figure 10 and Figure 11 are the sketch map of this analog result.Figure 10 is the isopleth map (under the situation of no fin) of radial direction composition.Figure 11 is the isopleth map (having under the situation of fin) of radial direction composition.And among two figure, all deeply feel more and show that speed is big more with tone.The relative velocity of the air-flow that consequently produces and the surrounding air of circumferencial direction is very big; Occupy mastery status (its influence is big); Like Figure 10 and shown in Figure 11, can know for along 2 times outside air-flows of radial direction, be equipped with tab member after; Comprise the tyre sidewall 1c along tire 1, air-flow (direction of arrow) increase of 1d direction composition, can get rid of tyre sidewall 1c, near the air of 1d more efficiently.

As above, the post-curing inflator of embodiment 1,2 comprises: clamping is upper and lower wheel rim mechanism 3,2 (the vulcanized tyre clamping devices) of upper and lower tire frame position 1a, the 1b of vulcanized tyre 1; Reach through wheel rim mechanism 3,2 and drive the rotary drive mechanism 10 of vulcanized tyre 1 high speed rotation; This post-curing inflator constitutes; So that this tire curing peripheral forced convertion that forms influence greater than free convection; Vulcanized tyre 1 rotates to come this rotary drive mechanism 10 to make; Thereby utilize forced convertion to take away vulcanized tyre 1 heat (promptly energetically vulcanized tyre 1 being cooled off) energetically, thus, can be at short notice vulcanized tyre 1 be cooled to below the set point of temperature from the outside.

At this moment; Vulcanized tyre 1 is the shape that benchmark is symmetry with the central point on the direction of principal axis; Thereby the forced convertion that produces of the high speed rotation of vulcanized tyre 1 has been to be symmetrical air-flow on the direction of principal axis of benchmark with center, tire curing equator, in addition, and the air that exists for the inboard of vulcanized tyre 1; Also can be created in monosymmetric air-flow on the direction of principal axis, thereby can obtain monosymmetric internal surface temperature distribution on direction of principal axis.That is, the vulcanized tyre state that forms the physics value of symmetry in both sides on the direction of principal axis that with the tire equator center is benchmark is realized down expanding cooling off.Therefore, vulcanized tyre 1 can realize with the center, equator being the symmetry cooling of both sides on the direction of principal axis of benchmark, thereby can improve after the cooling quality of vulcanized tyre 1, for example harmony, tapering etc.

Be in the present embodiment 1,2; As the cooling means of vulcanized tyre 1; Be so that the tire equator center of vulcanized tyre 1 be both sides on the direction of principal axis of benchmark demonstrate the physics value of symmetry and to form influence and form air-flow greater than the forced convertion of free convection in the periphery of vulcanized tyre 1 at this, make this vulcanized tyre 1 cooling of expanding.Therefore, under the effect of this forced convertion, balanced cooling on above-below direction and the circumferencial direction of vulcanized tyre 1 can be realized, thereby the quality of vulcanized tyre 1, for example harmony, tapering etc. can be improved after the cooling.And, because the air-flow that produces forced convertion character through the outside at vulcanized tyre 1 to be carrying out positive cooling from the outside to vulcanized tyre 1, thereby can realize the expansion cooling of vulcanized tyre 1 at short notice.

Particularly, in embodiment 1,2, make vulcanized tyre 1, thereby can when shortening cool time, improve the quality with the rotating speed high speed rotating more than the 100rpm.Lower velocity limit value about rotation at a high speed is the reason of 100rpm; As after state among Figure 15 and Figure 16 shown in the chart; Vulcanized tyre is rotated and when making it expand cooling with the rotating speed of 100rpm, compare with expand the down situation of cooling of non-rotary state, tapering can improve more than 30%; And can shorten cool time more than 20%, can obtain significant effect.In addition; When rotating vulcanized tyre 1 at a high speed with the rotating speed more than the 100rpm; Can vulcanized tyre 1 fully be cooled to the temperature that thermal contraction does not take place; So for example can prevent the cooled thermal contraction of carcass parts as fortifying fibre, reducing with the tire equator center is the difference of both sides physics value on the direction of principal axis of benchmark, thereby can improve harmony.

And; Rotate vulcanized tyre 1 at a high speed through rotating driving device 10; Make vulcanized tyre 1 in rotation, realize cooling, thereby need not to increase the operating cost of cooling, compared with the mode of drive source and pipeline with use cooling in the past simultaneously; Avoid maximization and structure complicated of device, also avoided the increase of component costs.

In addition; The rotation that utilizes rotating driving device 10 to produce comes near the mandatory eliminating air of (near sideway stance) the tyre sidewall 1c, 1d of vulcanized tyre 1; Be equipped with the air that imports cold air from the outside simultaneously and get rid of mechanism 41; Therefore compare with the situation of cooling with only rotating vulcanized tyre 1, can be in the shorter time vulcanized tyre 1 be cooled to below the set point of temperature.

Particularly; In embodiment 1; Air is got rid of to be equipped with in the mechanism 41 and is arranged in each wheel rim mechanism 3,2, comprises the tyre sidewall 1c along vulcanized tyre 1, the tab member 42 of 1d direction composition air-flow with each wheel rim mechanism 3,2 common rotation with generation; Through tab member 42 these simple structures being set at each wheel rim mechanism 3,2 place; Tyre sidewall 1c, near the air of 1d of vulcanized tyre 1 can be got rid of effectively, thereby more symmetrical physics value can be realized in the both sides on the direction of principal axis that with tire equator face center is benchmark.In addition, in the post-curing inflator of embodiment 2, also can be equipped with identical tab member 42.

Say again,, can select shape and configuration arbitrarily as long as tab member 42 can produce the tyre sidewall 1c that comprises along vulcanized tyre 1, the air-flow of 1d direction composition.For example the sheet number of tab member 42 can be an odd number, and the angle of inclination of each tab member 42, shape, size can have nothing in common with each other, and also can be made into plate shaped.In addition, in order to comprise more heterogeneous air-flow for tyre sidewall 1c, 1d vertical direction composition, the top of tab member 42 can bend towards tyre sidewall 1c, 1d one side of travel direction, or tab member 42 integral body can be to the travel direction tilt.

In addition, tab member 42 also can be set to satisfy in the desired site of vulcanized tyre 1, and the thickest position of tyre sidewall 1c, 1d etc. for example produces than other position form of this condition of high speed airflow more.At this moment, through the more air stream that flows of the desired site at vulcanized tyre 1, can take away than other position and more many heat, thereby can realize emphasis cooling desired site.Under more desirable state, realize cooling so can make vulcanized tyre 1.Above-mentioned " satisfying ... this condition " is meant; Be provided with sheet number, angle of inclination, shape etc. for for example tab member 42 are the air-flow variable factor of typical example; Through adjusting at least one in these a little air-flow variable factors, come to produce than the more air-flow in other position in the desired site of vulcanized tyre 1.

In addition; Air among the embodiment 1 is got rid of the partition member 43 of the 2nd area of space B of the tyre sidewall 1c, the 1d that are provided with the 1st area of space A that distinguishes the air inflow side in the tab member 42 and vulcanized tyre 1 in the mechanism 41 near; Thereby the 2nd air in the area of space B when heating up with vulcanized tyre 1 heat exchange; Because the 2nd area of space B is cut apart by partition member 43 and the 1st area of space A relatively, so can stop the air after the intensification to flow effectively to the 1st area of space A.So, only there is the preceding air of heat exchange in the 1st area of space A, this air flows into tab member 42, therefore can carry out the cooling of vulcanized tyre 1 more efficiently.In addition, in the post-curing inflator of embodiment 2, also can be equipped with identical partition member 43.

In addition, embodiment 1 air is got rid of mechanism 41 and is equipped with the cooling air supply mechanism 44 of airfoil parts 42 supplied with cooling air, and constitutes to vulcanized tyre 1 supplied with cooling air, thereby can cool off vulcanized tyre 1 more efficiently.In addition, in the post-curing inflator of embodiment 2, also can be equipped with identical cooling air supply mechanism 44.

In addition; Replacement makes expansion that vulcanized tyre 1 expands with the air mechanism of taking a breath when comprising 1 rotation of vulcanized tyre in the post-curing inflator of embodiment 1; Can cool off it in the inner product polar region of vulcanized tyre 1, thereby can cool off vulcanized tyre 1 more efficiently.In addition, in the post-curing inflator of embodiment 2, also can be equipped with identical ventilation mechanism.

Among the embodiment 1,2; As shown in Figure 1; Supporting is taken out of vulcanized tyre 1 and the cooling of expanding from the vulcanizer 102 of sulfidization molding as the green tire 107 of tire base, its comprise with in the cure time in the vulcanizer 102 vulcanized tyre 1 be cooled to the rotating speeds below the set point of temperature such as 80 ℃ and rotate the rotary drive mechanism 10 of vulcanized tyre 1 at a high speed.

Therefore; Can be positively sulfidization molding green tire 107 is processed till the vulcanized tyre 1 in vulcanizer 102 a sulfidization molding cool off vulcanized tyre 1 in circulation timei; Therefore need not behind the sulfidization molding to wait for that vulcanized tyre 1 is mounted to vulcanized tyre clamping device 2 and begins to expand and cools off.In addition, can vulcanized tyre clamping device 2 be controlled at essential minimum number, therefore can simplify the structure of post-curing inflator 101, reduce component costs and assembly cost simultaneously.Therefore in addition, vulcanized tyre clamping device 2 is set at the position of regulation, can improve the precision when vulcanized tyre 1 is mounted to vulcanized tyre clamping device 2.So, can with after the cooling of expanding the quality of vulcanized tyre 1 maintain higher state, reduce the fluctuation of quality aspect simultaneously.

In addition; In the present embodiment 1,2; As shown in Figure 3; Post-curing inflator is employed under same position and the posture through upper and lower wheel rim mechanism 3,2 (vulcanized tyre clamping devices) and carries out the entire process from clamping vulcanized tyre 1 to the cooling of expanding, and the fixed post-curing inflator that a place carries out the cool position of above-mentioned processing position only is set.Therefore, device structure is simple, thereby can improve mechanical precision, also can improve simultaneously the precision of tire curing carrying location, clamping etc., thereby harmony that can be through improving tire etc. are further improved the quality of tire.In addition, also can improve the reliability of equipment, reduce frequency and the expense thereof suspending, safeguard.In addition; For spinning upside down the expand cool position evolutionary mode of cooling of vulcanized tyre clamping device 2; Need keep at a certain distance away and dispose vulcanizer 102 and post-curing inflator 101, relative therewith, the cool position fixed form; The close that vulcanizer 102 and post-curing inflator are 101, thus can reduce device space (particularly before and after amplitude size) is set.So; Use unloader as carrying under the situation of the carrying mechanism of vulcanized tyre 1 to post-curing inflator 101 from vulcanizer 102; The radius of turn of this unloader reduces, so turning moment diminishes, and can be accurately vulcanized tyre 1 be carried to vulcanized tyre clamping device 2.

In addition; Air among the embodiment 1 is got rid of mechanism 41 and is directly utilized the rotary driving force of rotary drive mechanism 10 to rotate near the air of both sides face of vulcanized tyre 1; With the facial air-flow that forms in the both sides of vulcanized tyre 1 respectively; But, its constitute the rotation that utilizes rotary drive mechanism 10 to produce bring into play mandatory eliminating near the tyre sidewall 1c, 1d of vulcanized tyre 1 function of (near sideway stance) air get final product, himself can be and fix non-rotary structure.

In addition, also can be in the two sides portion of vulcanized tyre 1 symmetry or get rid of mechanism 41 respectively near air is set, at this moment collaborative with the rotation of vulcanized tyre 1, with advection forcibly or remove the tyre sidewall 1c of vulcanized tyre 1, near the air the 1d.According to above-mentioned formation, air is got rid of mechanism 41 and also can promptly be can't help to drive with the drive source that the vulcanized tyre clamping device is identical not through vulcanized tyre clamping device driving.At this moment, can drive it rotating, or to rotate with vulcanized tyre 1 different rotating speed with the 1 opposite direction of vulcanized tyre, thus, with vulcanized tyre 1 matches desired conditions under cool off.

In addition; Air is got rid of mechanism 41 and also can be made up of the 1st air eliminating mechanism and the 2nd air eliminating mechanism; The 1st air is got rid of mechanism and is utilized the rotary driving force of above-mentioned rotary drive mechanism to rotate near the air of a certain side surface part of vulcanized tyre 1; Formation with respect to the air-flow of this side surface part forcibly to get rid of; The 2nd air is got rid of mechanism and is arranged on tire curing another side symmetrically, and collaborative with above-mentioned tire curing rotation, with advection forcibly or stir near the tire curing opposite side face air with its eliminating.Say that again the air of opposite side is got rid of mechanism and can be adopted the fixed tab corresponding with tyre sidewall 1c, 1d or remove this rotating blade of fixing.

In addition; In the present embodiment 1,2; Through upper and lower wheel rim mechanism 3,2 (vulcanized tyre clamping devices) under the posture of horizontal arrangement clamping vulcanized tyre 1 make it rotation at a high speed; But, can not make it rotation at a high speed in the posture clamping of tilting vulcanized tyre 1 only for due to this yet, for example can the posture of vertical direction, promptly under the posture that is horizontal of the axle of vulcanized tyre 1 clamping vulcanized tyre 1 rotate at a high speed.When rotating at a high speed vulcanized tyre 1 under the posture of vertical direction, can further improve with the center, equator is the symmetry of direction of principal axis two sidewinds of benchmark, thereby further improves the symmetry of cooling, and the quality of direction such as harmony.

In addition; Among the embodiment 1,2; Being illustrated in one of the lower position of the horizontal frame 6 cooling structure of vulcanized tyre 1, but not only for due to this, also can adopt with horizontal frame 6 is that centre symmetry is provided with the structure that the mechanism of same structure spins upside down.

In addition; In the present embodiment 1,2; As shown in Figure 1; Post-curing inflator is employed under same position and the posture through upper and lower wheel rim mechanism 3,2 (vulcanized tyre clamping devices) and carries out the entire process from clamping vulcanized tyre 1 to the cooling of expanding, and the fixed post-curing inflator that a place carries out the cool position of above-mentioned processing position only is set.Therefore, device structure is simple, thereby can improve mechanical precision, also can improve simultaneously the precision of tire curing carrying location, clamping etc., thereby harmony that can be through improving tire etc. are further improved the quality of tire.In addition, also can improve the reliability of equipment, reduce frequency and the expense thereof suspending, safeguard.

More than based on desirable embodiment 1,2 explanation the present invention, as long as in the scope that does not exceed above aim, can carry out suitable change to the present invention.Promptly shown in figure 12, also can adopt in the post-curing inflator being fixed, and remove near tyre sidewall 1c, the 1d removal parts 51 of air and get rid of mechanism 41 as air with respect to the symmetrically arranged state of tyre sidewall 1c, 1d of vulcanized tyre 1.

Particularly, remove parts 51, to equate with the distance of tyre sidewall 1c, 1d with a side surface of the opposite face of tyre sidewall 1c, 1d and to be formed.And remove parts 51 and dispose up and down, clamping is tyre sidewall 1c, the 1d of vulcanized tyre 1.The removal parts 51 of upside are fixed on the tubular support component 22 through upside support component 52.On the other hand, the removal parts 51 of downside are fixed on the shaft supporting part 33c of lock shaft 33 through downside support component 53.

In addition, shown in figure 13, with annular region that tyre sidewall 1c, 1d face mutually in, dispose a plurality of removal parts 51 equally spacedly.And remove parts 51 be with the crooked plate object of radius of curvature that vulcanized tyre 1 outer ring face is suitable, and tilt with respect to the radial direction of vulcanized tyre 1.That is an end of removing parts 51 outer ring sides more is inclined to upper reaches one side of direction of rotation (direction of arrow among the figure) with respect to the other end.

In addition, an end of removal parts 51 outer ring sides also can more be inclined to a dirty side of direction of rotation (direction of arrow among the figure) with respect to the other end.In addition, removing parts 51 also can be provided with tab member 42, partition member 43 or 44 combinations of cooling air supply mechanism that the air of Fig. 3 is got rid of in the mechanism 41.Say again, remove parts 51, remove near this condition of air the tyre sidewall, do not limit and to be fixed on lock shaft and the cartridge as long as satisfy and to relatively rotate with respect to tire curing tyre sidewall.
