Description
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 tire distortion, substandard products 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 (Japanese patent gazette 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 (Japanese patent gazette 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 (Japanese patent gazette 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 finish 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 be subjected to 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, thereby temperature deviation or cooling deviation on tire circumferential direction, occur.In addition, also there are problems such as device structure complexity, with high costs, 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 the complicated of the maximization of equipment and structure, 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 conventional art problem just, the post-curing inflator that significantly rises 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 the complicated of the maximization of equipping and structure and 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 described vulcanized tyre is rotated.

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 (hereinafter referred to as lower rim mechanism 2) of horizontally disposed 1 downside of vulcanized tyre of clamping; With the clamping device of vulcanized tyre 3 of 1 upper side of clamping vulcanized tyre (hereinafter referred to as last 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 passing the line that central point 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 inner ring side of last wheel rim 4 is provided with the peristome 4a that can allow fixed axis 33 described later pass.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 and drive belt 13 by drive pulley 12 rotary driving force is delivered to follow-up pulley 11, and wheel rim attaching parts 5 and 4 rotations of last wheel rim 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 " herein 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 herein, 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, needs the cost of equipment of overspending and labour to guarantee security simultaneously.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 by 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 present symmetry, come to rotate at a high speed vulcanized tyre 1, thereby form the forced convertion of influence in the periphery of vulcanized tyre 1, simultaneously to the cooling of expanding of vulcanized tyre 1 greater than free convection." 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 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 Lock Part 32, lock shaft 33 and locking 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 and cylinder device 36 constitute locking with rotating mechanisms 34, and locking makes turning cylinder 35 rotations with rotating mechanism 34 by cylinder device 36, thereby make 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 gas supply assembly that expands under the vulcanized tyre 1 pressure effect in vulcanized tyre 1; Expand with the air mechanism of taking a breath with under situations such as vulcanized tyre 1 rotation, replacing.
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 slotting thorough cut 32c (notch part) between the adjacent lock part 32b32b.Insert thorough cut 32c and form the protuberance 33a that passes lock shaft 33.Say again, the as above locking mechanism 31 of Gou Chenging, by 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 enter or withdraw from depressed part 32a, on the other hand, for example when driving Lock Part 32 toward backwards rotation, 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 alignedly with the central shaft of its axle center and above-mentioned lower rim mechanism 2, 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.
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 allow 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 of parts of bearings.The as above lower rim mechanism 2 of Gou Chenging, the following tire frame position 1b by clamping 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 by air and implement except that rotating the vulcanized tyre 1 by 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 near the device of the air the tyre sidewall 1c1d of vulcanized tyre 1 side surface part.
That is it is by together rotating with wheel rim mechanism 32 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 32 outer ring portion of wheel rim mechanism equally spacedly.In addition, tab member 42 is the plate objects with the radius of curvature bending suitable with each wheel rim mechanism 32 outer ring face, and it tilts with respect to the radial direction of each wheel rim mechanism 32.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 the so-called wing that retreats.Thus, by the tab member 42 common rotation with each wheel rim mechanism 32, air is got rid of mechanism 41 and can be formed under the situation that does not reduce the relative velocity on the circumferencial direction and comprise along the side surface direction composition of vulcanized tyre 1 or outwards disperse the air-flow of composition 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 jointly with wheel rim mechanism, 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 the territory, tyre sidewall 1c1d lateral areas of tire 1 that air as tab member 42 flows into the 1st area of space A of a side and near the 2nd area of space B of tyre sidewall 1c1d one side of tire 1.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 driving force of the driving mechanism of establishing in addition beyond will rotary drive mechanism 10 to be delivered to the structure of tab member 42.When rotating relatively, phase place constantly changes on the direction of rotation of tire 1 and tab member 42, thereby can realize balanced more exhaust effect on tire circumferential direction.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 be driven by different driving mechanism be set respectively in the above and below of vulcanized tyre 1.The driving mechanism of the driving force of sending outside the rotary drive mechanism 10 also can only be set for the tab member 42 of tire curing top 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 be subjected to the influence of the asymmetry of equipment peripheral temperature, the temperature of tire curing upper portion is often too high, perhaps the upper portion of vulcanized tyre 1 asymmetric with lower portion (for example the shape of tyre sidewall 1c1d is different) and cooling velocity occur under the situation such as deviation, the cooling velocity of also adjustable close side part and lower portion.In addition, the shape of tab member 42 that also can be by 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 32 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.
As shown in Figures 1 and 2, after vulcanizer 102 was finished sulfidization molding, machine 104 liftings were handled and loaded in each rotation, rotation places tire anchor clamps 104B in each mould 110.Reduce tire anchor clamps 104B then and clamp vulcanized tyre 1.Then, lifting, 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 mentioned above, 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 with forward rotation under 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 in locking.The protuberance 33a of therefore, rising lock shaft 33 passes slotting thorough cut 32c and enters in the depressed part 32a.Then, after lock shaft 33 arrived 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 charges into the expansion air of regulation air pressure in vulcanized tyre 1 by 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 by 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, replaces to expand when keeping in the vulcanized tyre 1 certain pressure and uses air.So, discharge on the one hand with vulcanized tyre 1 and carry out the expansion air that heats up after the heat exchange, the expansion air of the low temperature before the supply heat exchange in vulcanized tyre 1 on the other hand, thus 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 by 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 be subjected to the influence of free convection and vulcanized tyre 1 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 on the direction of principal axis and vertical with it plane and vulcanized tyre 1 tyre surface 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 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 1c1d moves with respect to ambient air, the surperficial relative velocity that forms tyre sidewall 1c1d is zero and distributes away from the big more air-flow of surperficial relative velocity more, it is so-called speed boundary layer, 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, the temperature boundary layer of close tyre sidewall thins out.The thin more thermal resistance of this boundary layer is low more, and tyre sidewall 1c1d can realize cooling more apace.Vulcanized tyre 1 need with the speed boundary layer fully the speed of attenuation rotate at a high speed, its rotating speed should be more than the 100rpm, is preferably more than the 200rpm, more preferably more than the 300rpm.As further raising rotating speed, then can realize cooling at faster speed.
In addition, near the air the tyre sidewall 1c1d that heats up because of heat exchange is 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 32 rotates, the tab member 42 that sets within it also will be rotated, and promptly rotate on the axle center with each wheel rim mechanism 32 is the circumferencial direction at center.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 32 side is pushed into tire 1 direction by tab member 42 from partition member 43, form and comprise along the air-flow (wind) of the tyre sidewall 1c1d direction composition of vulcanized tyre 1.
Thus, near the high temperature air the tyre sidewall 1c1d after the heat exchange is with from 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 1c1d of vulcanized tyre 1 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 again, near the 2nd area of space B the tyre sidewall 1c1d by by partition member 43 with the 1st area of space A is relative isolates, 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 1c1d more efficiently.
In addition, when making as so vulcanized tyre 1 that rotation is with cooling at a high speed, the air of each tyre sidewall 1c1d of upside and downside flows along the peripheral direction of vulcanized tyre 1.So can prevent that tyre sidewall 1d with downside from finishing the air that heats up after the heat exchange and rising because of free convection and rotate to the appearance of this state of upside tyre sidewall 1c.Therefore, two tyre sidewall 1c1d of upside and downside can realize cooling under identical condition.In addition, this rotates at a high speed under the centrifugal action that produces down, and the air of vulcanized tyre 1 inside 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 by employing and to make the vulcanized tyre 1 can be with 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 the inside and outside agonic cooling of cooling, tire of tire shape and can adjust or shorten cool time, also can tune in a vulcanisation cycle and finish cooling.In other words, post-curing inflator 101 also can possess can be adjusted to structure and the function of finishing cooling in a vulcanisation cycle, 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 the above-below direction of vulcanized tyre 1 and the circumferencial direction, cooled vulcanized tyre 1 is with regard to the good quality of oblatio.
After as above finishing the cooling of vulcanized tyre 1, discharging expands use air, and in locking mechanism 31, Lock Part 32 is forward rotation under the driving of rotating mechanism 34 of locking usefulness, 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, as shown in Figures 1 and 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.
Another embodiment that has diagrammatically shown the post-curing inflator among the present invention among Fig. 5, Fig. 6, Fig. 5 are longitudinal sectional view, and Fig. 6 is a vertical view, has shown post-curing inflator etc. respectively.Wherein, the parts identical with the post-curing inflator 101 of embodiment 1 are paid with identical symbol, and omit explanation.In addition, though do not show among the figure, parts or mechanism that air is got rid of explanation among 41 embodiment such as grade 1 of mechanism can be set aptly as required also.
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 be with any rotating speed rotation under 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 by 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 the outer ring face of cartridge unit 76b, the joint cylinder barrel 80 that bar 80a in the vertical direction advance and retreat are moved; 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 supported and make rotation that cartridge unit 76b rotates in the horizontal direction with cylinder barrel 82 by outer cylinder member 76.
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 as above locking mechanism 83 of Gou Chenging, by 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 enter 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 structure is identical with post-curing inflator 101 among the embodiment 1.
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 enters 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 the expansion air of air pressure.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 by rotating shaft member 75 separated by a distancely in the appearance, simultaneously, vulcanized tyre 1 be expanded to the shape that formalizes and keep 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 freely rotate with respect to outer cylinder member 76.Afterwards, running motor 77 makes spindle unit 75 rotations by pulley and belt drives.So vulcanized tyre 1 cooling of under rotation at a high speed, expanding.
Below, carry out following simulated test, to confirm the cooling effect of the post-curing inflator in the present embodiment 12.
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 schematic diagram 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, the dark more speed of then representing of tone is big more.Its result as shown in Figures 7 and 8, the air that the tyre sidewall 1d portion of the downside of vulcanized tyre 1 of producing in the tire outside as can be known heats up rises, and rotates 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 the inboard free convection that produces lifting cord liner (belt inner liner) portion of tire as can be known, and the formation temperature layering, produce temperature difference up and down.
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 schematic diagram of this analog result, is radial direction and vertical direction speed vector figure.Its result as shown in Figure 9, produce as can be known and comprise along the air-flow (direction of arrow) of the forced convertion character of the tyre sidewall 1c1d direction composition of vulcanized tyre 1, be monosymmetric air-flow on the direction of principal axis of benchmark with the center, equator of vulcanized tyre 1 promptly, near the air the tyre sidewall 1c1d is benchmark bilateral symmetry and eliminating of being forced to 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 schematic diagram 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.Consequently the relative velocity of the surrounding air of air-flow of Chan Shenging and circumferencial direction is very big, occupy mastery status (its influence is big), as Figure 10 and shown in Figure 11, as can be known for along 2 times outside air-flows of radial direction, after being equipped with tab member, comprise along air-flow (direction of arrow) increase of the tyre sidewall 1c1d direction composition of tire 1, can get rid of near the air of tyre sidewall 1c1d more efficiently.
As above, the post-curing inflator of embodiment 12 comprises: clamping is last lower rim mechanism 32 (the vulcanized tyre clamping devices) of the frame of the tire up and down position 1a1b of vulcanized tyre 1; Reach by wheel rim mechanism 32 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 from the outside, thus, can be at short notice vulcanized tyre 1 be cooled to below the set point of temperature.
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, 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, vulcanized tyre forms in both sides on the direction of principal axis that with the tire equator center is benchmark under the state of physics value of symmetry and realizes the cooling of expanding.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 12, 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 present 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 the above-below direction of vulcanized tyre 1 and the circumferencial direction 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 by 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 12, 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 described later 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 the situation of the cooling of expanding under the 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, vulcanized tyre 1 fully can 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, minimizing is the difference of both sides physics value on the direction of principal axis of benchmark with the tire equator center, thereby can improve harmony.
And, rotate vulcanized tyre 1 at a high speed by 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 the complicated of the maximization of device and structure, 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 the tyre sidewall 1c1d (near sideway stance) 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 32, comprises along the tab member 42 of the tyre sidewall 1c1d direction composition air-flow of vulcanized tyre 1 with generation with each wheel rim mechanism 32 common rotation, by tab member 42 these simple structures are set at each wheel rim mechanism 32 place, near the air of tyre sidewall 1c1d 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, comprise along the air-flow of the tyre sidewall 1c1d direction composition of vulcanized tyre 1, can select shape and configuration arbitrarily as long as tab member 42 can produce.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 1c1d vertical direction composition, the top of tab member 42 can bend towards tyre sidewall 1c1d one side of travel direction, or tab member 42 integral body can be oblique to the travel direction inclination.
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 1c1d etc. for example produces than other position form of this condition of high speed airflow more.At this moment, by 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, by 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 and is provided with the 1st area of space A that distinguishes the air inflow side in the tab member 42 and near the partition member 43 of the 2nd area of space B of the tyre sidewall 1c1d of vulcanized tyre 1 in the mechanism 41, 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 with the 1st area of space A is relative cuts apart, therefore can be stoped the air after the intensification to flow to the 1st area of space A by partition member 43 effectively.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, 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 among the embodiment 1, 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, replace when comprising 1 rotation of vulcanized tyre in the post-curing inflator of embodiment 1 and make expansion that vulcanized tyre 1 expands with the air mechanism of taking a breath, 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 12, 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 made 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, vulcanized tyre clamping device 2 can 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 12, as shown in Figure 3, post-curing inflator employing lower rim mechanism 32 (vulcanized tyre clamping device) on passing through under same position and the posture 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 by 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, configuration vulcanizer 102 and post-curing inflator 101 need keep at a certain distance away, relative therewith, the cool position fixed form, the distance that vulcanizer 102 and post-curing inflator are 101 is very near, thus can reduce device space (particularly Qian Hou 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 1c1d 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 near the tyre sidewall 1c1d of vulcanized tyre 1 air.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 by vulcanized tyre clamping device driving.At this moment, can drive it and rotate, or with the rotational speed different with vulcanized tyre 1 with the direction opposite with vulcanized tyre 1, 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 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 1c1d or remove this fixing rotating blade.
In addition, in the present embodiment 12, by last lower rim mechanism 32 (vulcanized tyre clamping devices) under the posture of horizontal arrangement clamping vulcanized tyre 1 make it rotation at a high speed, but not only be defined in this, also can make it rotation at a high speed in the posture clamping of tilting vulcanized tyre 1, 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 12, being illustrated in one of the lower position of the horizontal frame 6 cooling structure of vulcanized tyre 1, but not only be defined in 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 12, as shown in Figure 1, post-curing inflator employing lower rim mechanism 32 (vulcanized tyre clamping device) on passing through under same position and the posture 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 by 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 12 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 as shown in figure 12, also can adopt in the post-curing inflator being fixed, and remove near the tyre sidewall 1c1d removing component 51 of air and get rid of mechanism 41 as air with respect to the symmetrically arranged state of tyre sidewall 1c1d of vulcanized tyre 1.
Particularly, removing component 51 is to equate with the distance of tyre sidewall 1c1d with a side surface of the opposite face of tyre sidewall 1c1d and to be formed.And removing component 51 disposes up and down, and clamping is the tyre sidewall 1c1d of vulcanized tyre 1.The removing component 51 of upside is fixed on the tubular support component 22 by upside support component 52.On the other hand, the removing component 51 of downside is fixed on the shaft supporting part 33c of lock shaft 33 by downside support component 53.
In addition, as shown in figure 13, with annular region that tyre sidewall 1c1d faces mutually in, dispose a plurality of removing components 51 equally spacedly.And removing component 51 be with the plate object of the radius of curvature bending 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 component 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.
