Detailed description of the invention
Below, with reference to accompanying drawing the present invention will be described based on embodiment.
1. pore must trimming device
Fig. 1 is the front view of the pore palpus trimming device schematically shown involved by present embodiment.As shown in Figure 1, cutting tool 2 is installed on keeper 1, in this, identical with pore palpus trimming device in the past.
But the pore palpus trimming device involved by present embodiment is provided with the lubricant application unit from lubricant atomizer 3 jet lubrication agent M, in this, different from pore palpus trimming device in the past.
That is, the pore involved by present embodiment must possess by trimming device: make the tire rotation unit (not shown) that tire T rotates towards white arrow direction; The finishing object surface Ta of the tire T in rotation is applied to the lubricant application unit of lubricant M; For the cutting tool 2 by pore palpus S excision; And the osculating element (not shown) that cutting tool 2 is contacted with finishing object surface Ta.
Like this, for the pore palpus trimming device involved by present embodiment, owing to must repair by S the pore of the finishing object surface Ta being coated with lubricant M, the surface of tire T after curing can cause damage or pore must be repaired by S with producing scorch therefore, it is possible to need not worry.
Particular determination is not carried out to lubricant application unit, as long as although can apply lubricant to finishing object surface Ta, no matter which kind of unit all can use, but, because atomization jetting device lubricant being carried out to atomized spray can more efficiently apply compared with other lubricant application unit, therefore preferred above-mentioned atomization jetting device.
In addition, if lubricant atomizer 3 and cutting tool 2 are installed integratedly, then can have no lavishly lubricant M to be only coated on required position, therefore, it is possible to complete coating with MIN atomized spray amount, thus preferred which.
In addition, for lubricant atomizer 3 and cutting tool 2, as shown in Figure 1, preferably lubricant atomizer 3 is configured at the tire rotation direction upstream side of cutting tool 2.By implementing this configuration, can repair immediately after coating lubricant M, therefore, even if when using the lubricant of volatile lubricant, mobility, also can give full play to the function of lubricant and pore must be repaired by S.
In addition, although be must repair the pore produced in tread surface in FIG, for produce pore must position that is finishing object surface for, except tread surface, also comprise the surface in bead part, sidewall and counterfort portion.In this case, multiple cutting tool and lubricant atomizer can be installed on pore palpus trimming device, and they are configured in the mode corresponding with each finishing object surface, must repair pore thus simultaneously.
2. pore must method for trimming
Next, pore must be described by method for trimming.Pore involved by present embodiment must method for trimming be repair after applying lubricant M to finishing object surface Ta again, in this, different from pore palpus method for trimming in the past.
That is, in the pore palpus method for trimming of present embodiment, tire T being rotated lubricant M is applied to the finishing object surface Ta of tire T, then, then by making cutting tool 2 contact with the finishing object surface Ta being coated with lubricant M, pore must be excised by S.
Like this, owing to being must S excision by pore at the finishing object surface Ta being coated with lubricant M, therefore as method for trimming in the past, larger frictional force can not be produced between cutting tool 2 and finishing object surface Ta, thus need not worry and can cause damage or produce scorch by surface of tyre after curing.
As shown in Figure 2, especially, when repair object surface Ta be provided with print establish word L time, because of this article word height easily and cutting tool 2 cut wiping to pieces, when cutting wiping to pieces with cutting tool 2, likely can form cutting damage I.But, in the pore palpus method for trimming of present embodiment, as mentioned above, owing to being coated with lubricant M, be therefore difficult to form cutting damage I.Especially, if word height is below 1.5mm, then that can suppress cutting tool 2 further cuts wiping to pieces, thus fully can reduce the possibility forming cutting damage I.In addition, owing to further suppress the heat produced because of friction, therefore, it is possible to reduce the generation probability of scorch.In addition, establish for word L for print, consider from viewpoints such as cosmetic look in recent years and mostly use recessed word, if adopt this recessed word, what then can not produce cutting tool 2 cuts wiping to pieces, therefore need not worry and can form cutting damage I, thus preferred which.
In the pore palpus method for trimming of present embodiment, although do not carry out particular determination to lubricant M, preferably use not siliceous lubricant.Silicon be such as in order to prevent from conveyer from blocking just being coated on conveyer or radial runout (runout) automatically measure in line be coated on wheel rim and in the process of manufacture tire widely used lubricant, although do not have problems when the amount being attached to tire is trace, but when the lubricant must repaired used as pore, as shown in Figure 3, the surface of tyre whitening after repairing can be caused, thus become the main cause of claim (claim).Particularly be easy to produce this tire whitening in truck, objective tire for vehicles (TB tire).The origin cause of formation of the present inventor to this tire whitening is studied, and has found out the principle of following generation whitening.
Fig. 4 is the figure of the principle of the whitening that this tire is described.Generally, in order to prevent the deterioration caused because of ozone, WAX is made an addition to airtyred sidewall (SW).But for this WAX under the solid state of white, it is similar to the chemical constitution of silicon at normal temperatures, and SP value is also close, therefore this WAX has the character easily mixed with silicon.
Therefore, if by silicon (silicone oil) for lubricant, then the WAX in rubber diffuses to the surface because of concentration gradient, thus dissolves diffusion in a layer of silicon.And then the heat produced during finishing facilitates the diffusion of WAX.After finishing is complete, if silicon layer cooling, then the WAX after diffusion can be stranded in SW surface and form WAX layer, therefore, and the whitening because of outside stimulus.Therefore, preferably not siliceous lubricant is used.
In addition, the experimental result of the present inventor is learnt and preferably water is used as lubricant M.First, in the case of using water, foreign matter can not be caused residual and can not bubble as interfacial agent etc., therefore easily obtaining finished product better, and also can not produce the whitening caused because of silicon.And, although water is unfavorable in this one side of effect reducing coefficient of friction compared with silicon, but if moisture film can be controlled in suitable scope by the adjustment water yield, the water drift phenomenon then caused by moisture film can reduce coefficient of friction, thus pore must can be excised and don't establish word to cause damage to print.
And, as the atomized spray amount of the water carried out SW when pore must be repaired, such as when making tire be in the state (interior pressure is 0) of unaerated and make this tire rotate at steady state with the speed of about 3m/ second, preferred atomized spray amount be 1ml/ second ~ 10ml/ second.In addition, preferably atomized spray is carried out intermittently from tire both sides with vaporific.Even if when water is used as lubricant, also can greasy property be given full play to by carrying out atomized spray in such a situa-tion.
(experimental example)
Below, the present invention is carried out more specifically bright based on experimental example.
1. the finishing of pore palpus
Size: the pneumatic tire using 11R22.516PR, carries out the finishing of pore palpus under each condition illustrated in Table 1.
2. test method and result of the test
(1) test method
A. the generation damaged
Respectively 100 pneumatic tires are repaired, the generation rate of damage is investigated, and evaluates investigation result with index.When the number of generation damage is more, index is less, thus is judged as bad order.Herein, when generation 20 place is damaged, index is set to 80.
B. whitening
Respectively 10 pneumatic tires are placed 1 week, then also divide the color of 10 grades to sidewall to evaluate by sensory experience, peak is set to 100, makes evaluation result realize indexation thus.The less tire of index is whiter, shows that outward appearance is poorer.
(2) result of the test
Result of the test has been shown in table 1.
[table 1]
As shown in Table 1, employing in the experimental example 1 of lubricant, experimental example 3 ~ 7, the generation of cutting damage and scorch is suppressed.On the other hand, in the experimental example 2 do not made with lubricator, more cutting damage and scorch is created.
In addition, as shown in Table 1, for water is used for lubricant and with print set the projecting height of word as below 1.5mm tire for object and carried out pore must the experimental example 3 of finishing and experimental example 4 ~ 6 for, generation and the whitening of cutting damage are suppressed in the lump, obtain good result.
Especially, for being provided with recessed word at finishing object surface Ta and the atomized spray amount of water is set to for the experimental example 3 of the 5ml/s in the scope of 1ml/s ~ 10ml/s, cutting damage, whitening degree in all obtain the highest evaluation.
In addition, even if for not being provided with the atomized spray amount of recessed word by water and being set to the experimental example 6 of nearly 15ml/s, although obtained the highest evaluation result, but the surface of tire after conditioning remains water droplet.
On the other hand, for silicon being used for the experimental example 1 of lubricant, the evaluation result of whitening is not good.In addition, for setting with print the projecting height of word as the tire of the 2.0mm experimental example 7 that is object, creating the wiping of cutting to pieces of cutting tool because Yin Yin establishes word, therefore cannot suppress the generation damaged fully.
Although describe the present invention based on embodiment above, the present invention is not limited to above-mentioned embodiment.In the scope identical and equivalent with the present invention, various change can be applied to above-mentioned embodiment.
