2. Description of the Related Art Conventionally, a layout of a tire vulcanizing equipment is a mold storing equipment for stocking a plurality of types of vulcanizing molds three-dimensionally, such as a three-dimensional warehouse for vulcanizing molds and a stacker crane attached thereto. Is relatively separated from a vulcanizing station, a mold opening / closing station, a mold exchanging station, a mold carrier, and the like as disclosed in, for example, JP-A-7-80846 as direct vulcanizing equipment. In general, under such a layout, loading and unloading of the vulcanization mold to and from the three-dimensional warehouse is performed by a stacker crane, and the vulcanization mold unloaded therefrom is
To replace the vulcanized mold after use, transport the uncured vulcanized mold to a mold changing station using another cargo handling means such as a forklift or crane, where the vulcanized mold is held in a mold holder that tightens and holds the vulcanized mold. The vulcanization mold is changed from a used one to a newly carried out one.

[0003] Also, in this case, the tire vulcanized at the vulcanization station is taken out of the vulcanization mold, and the unvulcanized tire is loaded into the vulcanization mold. For the vulcanized mold with the mold holder delivered to the station, open the vulcanized mold at the mold opening / closing station, take out the vulcanized tire from the vulcanized mold, and unvulcanize it there It is carried out by sequentially bringing in the tires and closing the vulcanization mold under the action of the mold holder, after which the vulcanization mold with the mold holder is activated on the basis of the reactivation of the mold carrier. Return to original vulcanization station.

[0004]

In such a layout, a vulcanizing station, a mold opening / closing station, a mold exchanging station, etc., as direct vulcanizing equipment, apart from a three-dimensional warehouse and a stacker crane, are provided. Are arranged in a plane, there is a problem that the space occupied by the plane becomes large, and here, a plurality of cargo handling means separated from each other, that is, the vulcanization mold is placed in a three-dimensional warehouse. In addition to the mold carrier that transports the vulcanized mold with the stacker crane and mold holder to and from the vulcanizing station and the mold opening / closing station, the vulcanized mold carried out of the three-dimensional warehouse is transported to the mold changing station. Independent transportation means such as forklifts and cranes Because, along with the increase capital cost,
The space occupied by the plane has to be further increased, and furthermore, there is a problem that the operating rate of each transport means is low and the equipment is wasted much.

The present invention has been made as a result of studying to solve such problems of the prior art, and an object of the present invention is to provide a vulcanizing facility in a plane space. It is an object of the present invention to provide a layout of a tire vulcanizing facility which can effectively reduce both the occupied space and the facility cost, and can increase the operation rate of the conveying means to advantageously eliminate waste of the facility.

At least one of the mold changing stations is arranged along the traveling route. Here, preferably, a preheating station for the vulcanization mold is also provided in the mold storage facility.

In this layout, a vulcanization station,
More preferably, the vulcanization and pre-heating stations are completely penetrated into the mold storage facility and are positioned, for example, in a vertical relationship with respect to the vulcanization mold stocked in the mold storage facility, The occupied planar space can be effectively reduced as compared with the related art in which the stations and the like are juxtaposed in the same plane as the mold storage facility.

Incidentally, the stacker crane described in the prior art functions only for loading and unloading the vulcanized mold to and from the mold storage facility when exchanging the mold. On the other hand, the stacker crane described in the prior art is used. Since the mold transport cart is substantially forced to stop when exchanging the mold, the present invention pays attention to such a point, and at least one stacker crane traveling along the mold storage facility as a transport means. In addition to loading and unloading vulcanization molds to and from the mold storage facility, this stacker crane also carries in and out the vulcanization molds that have been transported to and from the mold change station, and the opening and closing stations for the vulcanization station and the mold. Between the vulcanization mold and the mold holder. The arrangement or installation of the mold carrier trolley, forklift, crane, etc. described in the prior art is made unnecessary, thereby realizing an effective reduction of the equipment cost and the occupied space, and at the same time, greatly increasing the operation rate of the stacker crane. Of waste.

That is, in the layout according to the present invention, the stacker crane is used for the ordinary vulcanizing operation.
By traveling between the vulcanization station and the mold opening and closing station, the vulcanization mold with the mold holder is transported from the vulcanization station to the mold opening and closing station, and the vulcanized tire is taken out from the vulcanization mold,
After loading the unvulcanized tire there, a similar vulcanization mold with a mold holder can be returned and transported to the original vulcanization station. In addition, the exchange work of the vulcanization mold that has been used for another vulcanization mold is carried out by a stacker crane from the vulcanization station to the mold exchange station, the process of transporting the vulcanization mold with the mold holder, which requires replacement. The process of transporting the vulcanized mold after removing the vulcanized tire at the mold opening / closing station to the mold changing station together with the mold holder by using a stacker crane, and the same stacker crane to provide mold storage equipment, preferably provided there. Removing the required vulcanization mold from the preheating chamber, and transporting the vulcanization mold to the mold exchanging station in a required order, and then, after exchanging the vulcanization mold, the vulcanization mold with a mold holder. Return to the original vulcanization station Beauty, the used molds, each storage conveyance to the mold storage facility, with the same stacker crane by causing a required sequence can be terminated smoothly and quickly enough.

[0010] Thus, under the high operating rate of the stacker crane, it is possible to greatly reduce the occupied space and the equipment cost as compared with the case where other transport means are arranged or installed.

Here, when a large number of vulcanizing stations are provided in the mold storage facility, the stacker crane travels on the same traveling route, or travels on both sides of the mold storage facility. According to the latter, a mold opening / closing station, a mold changing station, and the like can be installed on both sides of the mold storage facility.
