Field of the Invention The present invention includes a multi-stage vulcanizing station for vulcanizing a tire, which requires a small installation space, a low installation cost, and allows a mold to be changed in a short time, and means for handling tires before and after vulcanization. It relates to a vulcanization system.

[0002]

2. Description of the Related Art When vulcanizing a tire, a vulcanizer 90 as illustrated in the front view of FIG. 15 has been widely used. Each vulcanization mold 92 of this vulcanizer 90
Actually makes the same movement on the left and right of the figure, but for simplicity,
The left half shows a state in which an unvulcanized tire 93 is put into a vulcanization mold 92, and the right half shows a state in which a vulcanized tire 94 is taken out from the vulcanization mold 92. In this vulcanizer 90, two vulcanizing molds 92 are arranged in a plane with the center axis of the tire being vertical, and can vulcanize two tires at a time. In addition, this vulcanizer 90

Is attached, so that it can be adapted to various production situations.

[0003]

By the way, when mass-producing tires, a large number of such vulcanizers 90 are conventionally installed, but according to this, all of the vulcanizing molds 92 are used. In addition to being arranged in a plane, the mold opening / closing means 9 whose operating time is extremely short compared to the operating time of the vulcanizing mold 92
8 and the means for handling the tires are also provided in the same number as the vulcanizer 90, so that there is a problem that the space efficiency and the equipment cost efficiency are poor. Also,
When exchanging the mold for size change, stop all the operation of the vulcanizer, remove the mold to the vulcanizer, and,
Installation must be performed. In addition, even after the vulcanization mold was attached, a preheating time was required to raise the temperature of the cooled mold to a predetermined temperature before starting the actual vulcanization. In addition, the downtime of the vulcanizer due to the exchange of these dies greatly impeded productivity. Further, a large space is required, such as a space for approaching the mold replacement, a work space for the mold replacement, and a space for temporarily placing the old and new molds, which is also a problem.

On the other hand, Japanese Patent Application Laid-Open No. 9-48026 discloses a vulcanizer in which a plurality of dies are arranged in such a manner that the center axis of the tire is oriented horizontally, and the four A tire vulcanizing apparatus has been proposed in which a single mold opening / closing apparatus is installed in response to the demand, and the installation space is reduced and the equipment cost is reduced. However, this proposal also requires that the molds be arranged in a plane, and that the mold opening / closing device also needs to move horizontally between the positions corresponding to the molds. Has not been able to achieve significant miniaturization. In addition, the problems of productivity reduction and space efficiency reduction due to vulcanization mold replacement have not been solved. The present invention has been made in view of such problems, and can significantly reduce installation space, effectively reduce equipment costs, and perform vulcanization without lowering productivity and space efficiency. It is an object of the present invention to provide a vulcanizing station and a vulcanizing system capable of exchanging a mold.

[0005]

The present invention has been made to achieve the above-mentioned object, and its gist structure and operation will be described below.

[0006] The vulcanizing system according to the first aspect of the present invention provides a vulcanizing mold that can be split by the action of an external force in a direction parallel to the center axis of the tire, which imparts a product outer shape to the tire. The mold assembly containing the core for specifying the inner surface shape is heated so that it can be inserted into and removed from the mold assembly with the central axis perpendicular to the space, and from above and below the accommodated mold assembly. An upper platen and a lower platen are provided, and vulcanizing presses, each of which operates independently, are arranged in two or more stages up and down, and accommodate the vulcanizing mold in the above-mentioned posture so that it can be taken in and out in at least two directions. At least one multi-stage vulcanization station, each vulcanization mold comprising at least one vulcanization mold storage shelf disposed above or below any of the vulcanization presses. Between the height corresponding to the less and vulcanizing mold accommodating shelf to the elevator base to lift displacement, in addition to entering out the mold assembly for each of the vulcanizing press,

Here, the core is a so-called core that specifies the inner shape of the tire by passing a fluid through a rubber bag.
It may be a bladder or a hard core formed by combining a plurality of rigid pieces. The tire may be handled as an assembly of the tire and the core while the core is fitted to the inner surface of the tire, and this assembly is hereinafter referred to as a "tire". When a bladder is used as the core, this is hereinafter referred to as "tire with bladder".
Call.

[0008] According to this, since each of the plurality of vulcanizing presses is arranged in a vertical relative positional relationship,
A number of molds can be installed in a plane space for one mold,
The installation space can be reduced. Also, since the respective vulcanizing presses stacked in multiple stages vertically operate independently of each other, it is possible to put and remove the respective mold assemblies of the respective vulcanizing presses in a required order and timing, Therefore, a small-sized device for taking in and out the mold assembly is sufficient, which can contribute to space saving.

Furthermore, since one mold opening / closing station shared by a plurality of vulcanizing presses is arranged adjacent to the multi-stage vulcanizing station, space efficiency can be improved. In addition, when moving the mold assembly into and out of each vulcanizing press, the lifting base of the mold opening and closing station is displaced up and down instead of moving in a plane. And a space-saving vulcanizing system can be configured.

[0010] In addition, at the time of mold replacement, the mold assembly transfer means of the mold opening and closing station uses the vulcanized mold from which the vulcanized tire has been removed to the vulcanized mold for mold replacement. Immediately after being temporarily placed on the storage shelf, it can be moved to a position corresponding to the next vulcanizing press, and the mold assembly immediately after vulcanization can be pulled out from the vulcanizing press. Further, the mold assembly transfer means transfers the mold assembly before the start of vulcanization to a vulcanizing press, and then pulls the prepared vulcanizing mold into a vulcanizing mold storage shelf, where it is not vulcanized. After setting the vulcanized tire, the mold assembly of this new vulcanizing mold can be transferred to a standby vulcanizing press. As described above, since the mold can be changed without stopping the vulcanization system, this does not cause a decrease in productivity. Further, since the vulcanization mold storage shelf is installed up and down on the vulcanization press, no extra space is required for this.
