BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing and conveying green tires and an apparatus therefor, and more specifically, it improves the molding productivity of green tires and can be used for various types of molding, and is in a preferable condition in terms of tire quality. Storage and transportation of green tires that can be stored in a storage device (three-dimensional storage shelf) installed for each tire molding machine, and can be taken out from the storage device and automatically carried out to the vulcanizer side when necessary. The present invention relates to a method and an apparatus thereof.

[0002]

Conventionally, various inventions have been proposed as a method of storing various green tires molded by a tire molding machine and, if necessary, conveying them to a vulcanizer. For example, as disclosed in JP-A-51-126275 or JP-A-51-123286, the molded article is suspended on the same rail by a storage device for a conveyor storing a green tire. A method of suspending, carrying, and installing a green tire that holds a self-propelled trolley and, while holding it, goes through a painter process or is directly propelled to a vulcanizer and mounted on the vulcanizer.

However, according to the present invention, one or two green tires are conveyed, and there is a limit to the conveyance on the same rail. In addition, the storage device is of conveyor type,
Although it is a first-come-first-served basis, it cannot be stored or stored freely for various types of molding production. In addition, for various types of production, the number of storages must be increased, which requires a large space. Further, the storage device and the vulcanizer are attached in correspondence with each other, and there is a possibility that the synchronization may be lost due to the difference in the cycle between molding and vulcanization.

Further, the tire quality is greatly affected by the fact that the green tires are stored in a storage device on a flat surface and the storage environment is a normal factory environment (not air-conditioned). Further, in the invention of the automatic transporting device for raw tires between the molding and vulcanizing steps disclosed in Japanese Patent Laid-Open No. 62-251125, raw tires are placed on a tray and transported by an unmanned vehicle, and only the raw tires are stored in an intermediate three-dimensional shelf. In this method, an unmanned vehicle on the vulcanization side puts it on a tray and supplies it to a pallet stand in front of the vulcanizer.

However, this raw tire automatic conveying equipment requires an AGV system for both the molding process and the vulcanization process, which increases the cost and requires a considerably large space. In addition, since multiple storage units and vulcanizers are installed in one storage facility, the processing capacity of the storage facility is significantly burdened, and this capability also increases the production speed of the molding and vulcanizers. Is constrained. Further, the air conditioner is not provided as a storage facility, which has a great influence on the tire quality.

Further, in the invention of the raw tire supply equipment between the molding and vulcanizing steps disclosed in Japanese Patent Laid-Open No. 63-209904, a tray for loading 12 tires is carried by an unmanned vehicle and a conveyor to a three-dimensional shelf in front of the vulcanizer. It is a facility to store and supply to the pallet stand of each vulcanizer. However, since the cycle time of each vulcanizer is different in this raw tire supply equipment, when a request is made from several units at the same time, a waiting time occurs in the vulcanizer. Also,
Since there is a pallet stand, stacker rail, etc. in front of each vulcanizer, there is a problem in vulcanizer maintenance. Especially, there is a problem that it hinders the frequent setup change work.

The present invention has been devised in view of such conventional problems, and by installing a storage device (three-dimensional storage rack) in each air conditioning zone for each tire molding machine, a green space can be saved in a small space. It is possible to improve the molding productivity of tires, to support various types of production in molding, and to store it in a favorable condition for tire quality, and to take it out from the storage device and carry it to the vulcanizer side if necessary. It is an object of the present invention to provide a method of storing and conveying a green tire and a device therefor.
