Embodiment
Below, with reference to accompanying drawing, embodiments of the present invention are described.In addition, in the following description, use the term of expression specific direction and position (such as required, comprise " on ", D score, " side ", " end " term), the use of these term is the invention easy understand in order to make with reference to accompanying drawing, and technical scope of the present invention be can't help the meaning of these terms and limited.In addition, following illustrative in nature is only example, does not limit the present invention, its applicable thing or its purposes.
Fig. 1 is the cut-open view of the green tire 1 of present embodiment.Green tire 1 is made up of (in FIG, omitting miscellaneous part) inner liner 2, bead core 3, belt 4, sidewall 5, tyre surface 6 etc.Green tire 1 is placed in mould, the capsule of insertion inner circumferential side is expanded and carries out vulcanization forming, form tire 7 thus.Fig. 2 represents the cut-open view of radial.
, before green tire 1 being shaped vulcanization forming is carried out to tire 7, be handled as follows the rubber flowing of inspection when vulcanization forming and whether suitably carry out.In the present embodiment, the sidewall 10 of green tire 1 is pasted the identification strip 8 being used for green tire trial-production, carries out vulcanization forming.
Can will have the material of the fusing point that can not melt in vulcanization forming described later, and when there is rubber flowing when the vulcanization forming of green tire 1, the material that can move elastic deformation along with it is for described identification strip 8.Particularly, can use the NR copy film of film-form as thick in 0.05mm for natural rubber (NR:NaturalRubber) making case.In addition, as shown in Fig. 3 (a), on the surface of identification strip 8, be printed with and arrange the pattern that two arrange the mark 9 that the circle being 10mm by diameter is formed along its length.Be configured to be point cantact between circle adjacent on length direction and Width.In circle, be printed with consecutive number (0 ~ 9) from the end side of identification strip 8 to another side.In addition, consecutive number is not limited to numeral, also can pay letter and wait other symbols (such as, a, b, c ... Deng).In a word, as long as can the symbol of specific each mark.
In the sidewall 10 that the identification strip 8 be made up of said structure is radially pasted onto green tire 1 and bead part 11.Paste position can be the entirety of sidewall 10 and bead part 11, also can be the first half of sidewall 10, Lower Half or pars intermedia.And then, shoulder portion 12 can also be comprised.
So, on the identification strip 8 of sidewall etc. being pasted onto green tire 1, each mark 9 is circle, be line symmetry relatively by the arbitrary line at its center.Particularly the relative straight line along the extension of green tire 1 radial direction and the straight line symmetry in line respectively with this linear vertical, be conducive to the rubber flowing after checking vulcanization forming.
The green tire 1 being pasted with described identification strip 8 is configured in mould.Now, capsule is inserted at the internal side diameter of green tire 1.Then, by close die, capsule is expanded, carry out vulcanization forming.
Fig. 3 (b) represents the state of the identification strip 8 on the tire 7 that obtained by vulcanization forming.In this embodiment, the lower side of identification strip 8 from the sidewall 10 of green tire 1 is pasted to bead part 11 ground, and vulcanization forming.After known vulcanization forming, (represent with arrow a in figure) between the number 0 and 1 respectively on identification strip 8, (represent with arrow b in figure) between 2 and 3, between 5 and 6, (in figure, represent with arrow c) that failing to obtain suitable rubber flows.Such as, between number 2 and 3 and between 5 and 6, boundary member overlap is become, the state of conquassation in the longitudinal direction.That is, can infer and to nip in the sidewall 10 of the tire 7 obtained, be i.e. so-called flowing crackle.
In addition, the result of vulcanization forming, what tire 7 occurred is bad except described nipping, and also has surface concave (wound or scorching) and air to enter.Scorching can wait the change of surface gloss to judge according to the word dimness of such as identification strip 8.Can infer that mark 9 overlapping that gas such as to enter between number 2 and 3, between 5 and 6 at each region occurs.In addition, near surface of tyre, there is gas when entering, expand from the teeth outwards.Therefore, it is possible to according to causing the vision shape of the mark 9 changed to infer the generation that gas enters because of this expansion.
So, as long as observe the state of each mark 9 of the identification strip 8 on the tire 7 after vulcanization forming, the state that rubber when just can grasp vulcanization forming effectively flows.Especially, due to each mark 9 with point cantact radial and circumferential any on arrange all continuously, and pay upper numeral, whether occur bad therefore, it is possible to rest in optional position at a glance.Because of ground, based on this result, carry out the length adjusting the material used, or the adjustment operation of amendment mould structure.In the amendment of mould structure, adjusted the easness of rubber flowing by the position or quantity changing air vent, prevent unsuitable rubber from flowing thus.
If again carry out vulcanization forming after the adjustment end of job, then can improve the state of rubber flowing.In this case, the vulcanization forming pasting identification strip 8 can again be carried out.Like this, by carrying out adjusting post-job vulcanization forming, rubber being flowed suitably, the generation of above-mentioned bad (nip, air enters, scorching) can be prevented.
In addition, the present invention is not limited to the structure that described embodiment is recorded, and can carry out various change.
In the above-described embodiment, the mark 9 of circle is arranged to point cantact in the radial direction and circumference of green tire 1, forms pattern thus, but also as shown in Fig. 4 (a), in the drawings Width can be arranged the large gap of a circle.In addition, as shown in Fig. 4 (b), on longitudinal in the drawings, the large gap of a circle can also be set.
In addition, in the above-described embodiment, form pattern by the mark 9 of circle, but also can be the such as structure shown in Fig. 4 (c) or Fig. 4 (d).But, if circle, when the identification strip 8 manufacture experimently for green tire pastes in the sidewall 10 of green tire 1 and bead part 11, even if radial skew relatively, the flowing of the rubber of the radial direction of tire 7 and circumference also can be checked whether suitably to carry out.
In Fig. 4 (c), being formed as in cancellate frame line, pay upper consecutive number (0 ~ 9) from the end side of the frame line being positioned at central authorities to another side.
In Fig. 4 (d), to specify Spacing to straight line formation scale, in the side of each scale, on paying, increase by the numeral of 10 successively from 0 to 100.
In addition, in the above-described embodiment, identification strip prints the pattern be made up of multiple mark 9, identification strip 8 is pasted on green tire 1, but also can be constructed as follows.
That is, described pattern can directly be printed on green tire 1, also can be formed on the colorful rubber beyond black.
In the former case, such as, reproduction technology can be utilized.
In the latter case, the colorful rubber that thickness is 0.3 ~ 0.4mm degree is pasted.When utilizing colorful rubber, even if when causing surface portion to invade inner because of rubber flowing, also by cutting off tire 7, and can easily grasp its intrusion state, therefore preferably.
