Description

Tire Vulcanizing Equipment and Tire Vulcanizing Method {TIRE VULCANIZING SYSTEM AND TIRE VULCANIZING METHOD}

The present invention relates to a tire vulcanization plant and a tire vulcanization method for performing tire vulcanization, mold deformation, bladder deformation, mold preheating and the like.

In the conventional fully automatic tire vulcanizing press, the working time for loading, forming and unloading of the green tire is heated / pressurized while the tire mold assembly is closed. It is much shorter than the time to vulcanize by introducing the medium into the tire. Therefore, the tire mold opening and closing device and the tire loading and unloading device for opening / closing the tire mold assembly for loading / unloading the tire have low work efficiency.

In order to solve this problem, the applicant of the present invention has proposed a tire vulcanization facility disclosed in Japanese Patent Laid-Open No. 95-80846.

As shown in Figs. 16 and 17, these tire vulcanization facilities are vulcanization stations 501a and 501b, mold opening and closing stations 502a and 502b, tire mold conveyers 503a and 503b, and tire mold conveyer rails 504. ), Mold beds 505a, 505b ...), unloader 507a, loader 508a, vulcanized tire conveying conveyor 509a, live tire rack 510a and mold deformation station 511 To deform the tread mold, the sidewall mold, and the like in the tire mold assembly Ma to accommodate the specification change of the tire to be vulcanized, and to deform the inflatable bladder.

In such a tire vulcanization facility, the vulcanized tire mold assembly Mc is transferred from the vulcanization station 501a (or 501b) in which the plurality of tire mold assemblies Mc vulcanized are arranged to the tire mold conveyer 503a. It is accommodated and conveyed to the mold opening / closing station 502a (or 502b).

After the tire mold assembly Mc conveyed to the mold opening and closing station 502a is connected to the tire mold opening and closing device 506a (or 506b), the tire mold assembly Mc is opened by the tire mold opening and closing device 506a, The vulcanized tire is unloaded by the unloader 507a attached to the tire mold opening and closing device 506a. The green tire is then loaded using the loader 508a attached to the tire mold opening and closing device 506a. The loaded tire is molded during the tire mold closing step, and after the tire mold assembly Mc is closed, the heating / pressing medium is introduced into the tire and sealed, whereby the tire vulcanizing step is started.

Subsequently, the tire mold assembly Mc having started to be vulcanized is separated from the tire mold opening and closing device 506a, placed on the tire mold conveying machine 503a and conveyed, and returned to the vulcanization stations 501a, 501b ... .

In the above-described conventional tire vulcanization plant, a discharge device (control valve and conduit) for discharging the heating / pressurizing medium in the bladder is provided to each vulcanization station to shorten the working time at the mold opening and closing station. Therefore, such a facility is undesirable from an economic point of view. In particular, such a facility, in which control valves and conduits are provided separately for vulcanization control, has such disadvantages in economic terms when used in a facility for mass production of tires having the same vulcanization time.

In addition, when a conventional tire vulcanization facility is used in a production facility for small tires, such as tires for passenger vehicles, where the vulcanization time is very short, such as 8 to 12 seconds, such a facility needs the following matters.

In such a facility, the time for the mold conveying device to accept the tire mold assembly at the vulcanization station, the time for completing the work at the mold opening and closing station, and the time for the closed tire mold assembly to be transported back to the vulcanization station should be as short as possible. . The reason is that the same mold conveying device is used in both directions, so that if the mold assembly is conveyed to the mold conveying device, the time interval until the next casting conveyance is increased, and thus the number of molds constituting the tire vulcanization equipment cannot be increased. This is because a problem that economic efficiency is lowered is caused.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is generally used for a loaded mold assembly by having the discharge device not disposed at each vulcanization station but just before the mold loading side of the mold opening and closing station. To provide a more economic tire device installation and tire vulcanization method.

Further, another object of the present invention is that the vulcanization control valve or the like is not disposed at each vulcanization station, and the heating / pressing medium supply station is disposed on the mold unloading side of the mold opening / closing station, whereby It is to provide a more economical tire vulcanization plant and a tire vulcanization method which are generally used for feeding into a bladder of an unloaded mold assembly from and also for feeding a heating medium into a mold outside heating chamber.

In addition, another object of the present invention is that the first conveyer conveys the tire mold assembly from the mold opening and closing apparatus to the vulcanization station, and the second conveyer conveys the tire mold assembly from the vulcanization station to the mold opening and closing apparatus, thereby shortening the conveying time. It is to provide a more economic tire vulcanization equipment in which the number of tire molds constituting the equipment is increased.

For example, if the vulcanization time is 10 minutes, the conveyer reciprocating time is 40 seconds, and the processing time at the mold opening / closing station is 80 seconds, Japanese Patent Application Laid-Open No. 95-80846 Is disclosed.

The number of molds that can be processed by one mold opening and closing station is N1 = 10 × 60 / (40 + 80) = 5. . . 5 molds.

On the other hand, in the case of the installation according to the invention, the number of molds that can be processed by one mold opening and closing station is N2 = 10 x 60/80 = 7.5. . .7 molds, the number of molds that can be processed by the first and second mold conveyers is N3 = 10 x 60/40 = 15. . . 15 molds.

For the entire installation, the number of molds that can be processed is up to seven molds. In the system according to the present invention, the number of molds can be increased in comparison with the conventional equipment disclosed in Japanese Patent Laid-Open No. 95-80846.

In order to further increase the number of molds, the processing capacity of the mold opening and closing station should be increased as is apparent from the above calculated example. According to one solution to this problem, the two opening and closing stations only have to be arranged. However, this solution is not economically desirable.

Accordingly, the applicant of the present invention proposes a vulcanization facility in which the processing process of the mold opening and closing station is increased by performing the work process at the mold opening and closing station outside the mold opening and closing station.

In particular, the processing time of 80 seconds at the mold opening and closing station is a) time for opening and closing the mold (about 30 seconds), b) working time for the vulcanized tire removing device (about 10 seconds), c) spaced apart from the vulcanized tire. Bladder operating time (approximately 10 seconds) for peeling the bladder, d) operating time (approximately 10 seconds) of the live tire feeder, e) time for inserting the bladder into the live tire and forming it (approximately 20 seconds) Note that it consists of).

The processing capacity of the mold opening and closing station increases with the bladder assembly as it removes about 30 seconds (times c) and e) by means by which the vulcanized tire is separated from the mold and moved outside of the mold opening and closing station. In this regard, bladder peeled off the vulcanized tire. The bladder is inserted into the raw tire and formed in other bladder assemblies and tires, which are immediately supplied to the mold after separating the vulcanized tire and bladder assembly from the mold.

According to this method, trial calculations can be made with a vulcanization time of 10 minutes in the same manner as in the above calculation example.

The number of molds [N = 10 × 60 / (80-30) = 12] that can be processed by one mold opening and closing station is 12 molds.

The number of molds [N = 10 × 60/40 = 15] that can be processed by the first and second mold conveyers is 15 molds.
