Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire vulcanizing method, and more particularly, to a tire vulcanizing step and a step of charging a green tire into a sector mold of a vulcanizing container in a separate step. The present invention relates to a novel tire vulcanization method that improves tire productivity and uniformity in vulcanization.

[0002]

2. Description of the Related Art A conventional vulcanizing method of a tire vulcanizer using a sectional container is a method in which a green tire is put into a sector mold provided in the vulcanizer, and vulcanization is performed after clamping. .

That is, a bladder mechanism is incorporated at the center of a sector mold provided in a tire vulcanizer. When vulcanizing a green tire, the sector mold in an open state is used. Green tires are loaded and installed in the bladder mechanism provided in the center.

Then, the vulcanizer body is operated via a lifting / lowering / pressurizing means to lower the upper mold attached to the inner top plate, and to press the side surface of the green tire against the lower mold attached to the base plate. At the same time, each sector mold is moved horizontally through a sectional container consisting of an outer ring and a segment attached to the top plate of the vulcanizer and pressed against the tread of the green tire. A heating and pressurized fluid such as steam is introduced into the tire via a bladder, and vulcanization is performed while applying an internal pressure to the tire.

[0005]

However, since the conventional vulcanization method as described above has a structure in which the sector mold and the vulcanization mechanism are integrated, during the vulcanization of the tire, It is necessary to keep the green tire formed by the molding machine on standby, and therefore, there is a problem that productivity cannot be improved, and the apparatus itself is large and requires a large space. Since the setting to the sector mold and the vulcanization are performed in the same configuration, there is a problem that the uniformity of the tire cannot be improved.

SUMMARY OF THE INVENTION It is an object of the present invention to improve productivity and improve tire uniformity by performing a step of setting a green tire in a sector mold and a step of vulcanizing in separate steps. It is possible to make the whole device compact.
An object of the present invention is to provide a tire vulcanizing method that can cope with a small space.

[0007]

In order to achieve the above object, the present invention conveys a green tire molded by a tire molding machine to a bladder setting device by a conveying device, sets the green tire, and then inserts and removes the green tire. Put the vulcanizing container in the open state waiting on the centering device by the device into the sector mold, clamp the sector mold with the press device, transport the vulcanizing container to the vulcanizing device, and heat and vulcanize. After that, the vulcanizing container is transported again to the pressing process, the sector mold is opened, and then transported to the centering device.The molded tire is taken out by the tire loading / unloading device and transported to the next process. It is an abstract.

[0008] Further, while the green tire in the vulcanizing container is being vulcanized by the vulcanizing apparatus, the next green tire is put into the sector mold of the vulcanizing container to perform pre-setup. Is also possible.

According to the present invention, a green tire molded by a tire molding machine is transported to a bladder setting device by a transport device, the green tire is set on the bladder, and shaping is performed. The green tire into the sector mold of the vulcanizing container that has been opened by the tire loading / unloading device, centering the mold, clamping the sector mold, and vulcanizing the mold. Transport the vulcanizing container to the vulcanizing unit,
Vulcanizing, removing the vulcanized container from the vulcanizing device, opening the sector mold of the vulcanized container and removing the molded tire, and moving the removed tire to the next step Transporting and returning the vulcanizing container provided with the sector mold to the step of centering the green tire.In such a step, the setting step of the green tire in the sector mold and the vulcanizing step are separated. By performing the process, the productivity can be improved, the uniformity of the tire can be improved, and the cost of the tire can be reduced.

[0010] Further, by performing the step of setting the green tire in the sector mold and the step of vulcanizing in separate steps, the entire apparatus can be made compact and, as a result,
It can handle even small spaces.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic structural view of a tire vulcanizing method embodying the present invention, in which a green tire W formed by a tire forming machine is conveyed to a vulcanizing apparatus, and until the formed tire is unloaded. Are performed by the following steps.

That is, the green tire W formed by the second-stage forming machine 1 is gripped by the transfer device 2 and transferred to the bladder setting device 3, where the green tire W is set on the bladder and shaped. Next, the green tire W on which the bladder is set is loaded into the sector mold 7 of the vulcanizing container 6 in an open state, which stands by the centering device 5 by the tire loading / unloading device 4, and is centered.

Thereafter, the sector mold 7 of the vulcanizing container 6 is conveyed to a press 9 via a conveying device 8 such as a conveyor and clamped, and the vulcanizing container 6 containing the sector mold 7 is vulcanized. It is transported to the device 10. Then, after heating and vulcanizing for a predetermined time in the vulcanizing apparatus 10, the vulcanizing container 6 whose vulcanization is completed is carried out from the vulcanizing apparatus 10 to the press apparatus 9.

In the pressing device 9, after the sector mold 7 of the vulcanizing container 6 is opened, it is conveyed to the centering device 5 via the conveying device 8, and the formed tire Wa
Is taken out by the tire loading / unloading device 4 and transported to the next step by the tire transporting conveyor 12 through the cooling device 11.

As described above, in the present invention, the step of setting the molded green tire W in the sector mold 7 and the step of vulcanizing are performed in separate steps, so that the green tire W is formed into a mold during tire vulcanization. It can be set to perform continuous production, thereby improving the productivity of the tire.In addition, the uniformity of the tire must be reduced in order not to set the green tire in the mold inside the vulcanizer. It can be improved.

Further, by arranging the entire apparatus on a line, each apparatus can be made compact, so that it can be used even in a small space.

[0018]

According to the present invention, the green tire molded by the tire molding machine as described above is transported to a bladder setting device by a transport device and set, and then the green tire is loaded by a tire loading / unloading device by a centering device. Put the waiting vulcanizing container into the sector mold of the vulcanizing container in the open state, clamp the sector mold with a press device, transport the vulcanizing container to the vulcanizing device, heat and vulcanize it, The container is again carried out to the press process, and after releasing the sector mold, the container is conveyed to a centering device, and the formed tire is loaded into the tire.
Since it is taken out by the take-out device and conveyed to the next step, the following excellent effects can be obtained. (a). By setting the green tire in the sector mold and performing the vulcanization step in separate steps, it is possible to set the green tire in the mold during tire vulcanization and perform continuous production. Thereby, the productivity of the tire can be improved. (b) Since the green tire is not set in the mold inside the vulcanizer, the uniformity of the tire can be improved. (c) By arranging the entire device on the line, each device can be configured compactly, so that it can be used even in a small space.
