Description

本発明は、タイヤ加硫装置において、金型によって加硫成形された加硫後タイヤを冷却するために用いられる加硫後タイヤ冷却装置（ＰＣＩ装置：ポスト・キュア・インフレータ）に関する。 The present invention relates to a post-vulcanized tire cooling device (PCI device: post-cure inflator) used for cooling a post-vulcanized tire vulcanized by a mold in a tire vulcanizing device.

タイヤ加硫装置には、金型によって加硫成形された加硫後タイヤを冷却するための加硫後タイヤ冷却装置が設けられている。
この加硫後タイヤ冷却装置は、加硫後タイヤの内部にエアを供給して加硫後タイヤを内部から加圧させてタイヤ形状を保持させると共に、加硫後タイヤの上側ビード部と下側ビード部を上リムと下リムによって支持させるもので、従来は、この支持状態のまま自然放熱により冷却させるようになっている。 The tire vulcanizing device is provided with a post-vulcanized tire cooling device for cooling the vulcanized tire vulcanized and molded by a mold.
The vulcanized tire cooling device supplies air to the inside of the vulcanized tire, pressurizes the vulcanized tire from the inside to maintain the tire shape, and also holds the upper bead portion and the lower side of the vulcanized tire. The bead portion is supported by an upper rim and a lower rim. Conventionally, the bead portion is cooled by natural heat radiation while being in this supported state.

このような自然放熱による冷却では、冷却時間が長くなるという問題があり、このため、加硫後タイヤの外周面に風を吹き付けることで強制的に冷却させるようにした加硫後タイヤ冷却装置が提案されている（特許文献１参照）。 In such cooling by natural heat dissipation, there is a problem that the cooling time becomes long. For this reason, a vulcanized tire cooling device that is forced to cool by blowing wind on the outer peripheral surface of the vulcanized tire is provided. It has been proposed (see Patent Document 1).

この加硫後タイヤ冷却装置は、加硫後タイヤの外周に沿うように環状送気管を配管させ、この環状送気管に加硫後タイヤの外周面に風を吹き付けるようにノズル口を設け、このノズル口からの風の吹き付けによって加硫後タイヤを冷却させる構造になっている。 This post-vulcanized tire cooling device has an annular air pipe arranged along the outer circumference of the tire after vulcanization, and a nozzle port is provided in the annular air pipe so as to blow wind on the outer peripheral surface of the tire after vulcanization. The tire is cooled after vulcanization by blowing wind from the nozzle opening.

しかしながら、環状送気管のノズル口から加硫後タイヤの外周面に風を吹き付けるようにした従来の加硫後タイヤ冷却装置では、ノズル口からの吹き付けが局部的（スポット吹き付け）になるため、風が当る場所と、風が当らない場所とで冷却度合が不均一になり、タイヤバランス等のユニフォーミティーや性能が低下してしまうという問題があった。
又、風の吹き付けに伴い、加硫後タイヤから油煙が発生するが、従来では油煙の放散を遮る部材を備えていないため、油煙が周辺の部品等に付着し、これらを汚損させたり、動作不良を生じさせたりするといった問題があった。
特開２００２−３０７４４４号公報 However, in the conventional post-vulcanized tire cooling device in which wind is blown from the nozzle port of the annular air supply pipe to the outer peripheral surface of the vulcanized tire, since the spray from the nozzle port is localized (spot spray), There is a problem that the degree of cooling becomes uneven between the place where the wind is hit and the place where the wind is not hit, resulting in a decrease in uniformity and performance such as tire balance.
In addition, oil is generated from the tire after vulcanization with the blowing of wind, but since there is no member to block the diffusion of oil smoke in the past, the oil smoke adheres to surrounding parts, etc. There was a problem of causing defects.
JP 2002-307444 A

本発明は、加硫後タイヤに対して吹き付けた風が加硫後タイヤの外周面に満遍なく行き渡るようにさせることで均一な冷却を促すと共に冷却時間を短縮させることができ、又、加硫後タイヤから発生した油煙の放散を遮ることができるようにした加硫後タイヤ冷却装置を提供することを課題としている。 The present invention can promote uniform cooling and reduce the cooling time by allowing the wind blown to the tire after vulcanization to spread evenly on the outer peripheral surface of the tire after vulcanization. It is an object of the present invention to provide a post-vulcanized tire cooling device that can block the diffusion of oil smoke generated from a tire.

上記の課題を解決するために、本発明（請求項１）の加硫後タイヤ冷却装置は、

The plurality of air blowing means are air blowing fans, and generally face in the circumferential direction of the tubular hood so as to face the annular gap in a state set in a wind direction that blows wind on the outer peripheral surface of the vulcanized tire. It was set as the structure arrange | positioned at equal intervals.

又、本発明（請求項２）の加硫後タイヤ冷却装置は、
請求項１記載の加硫後タイヤ冷却装置において、複数個の送風手段の風向方向が、加硫後タイヤの中心を通る半径線から一定の角度を持つように設定されている構成とした。 Further, the tire cooling device after vulcanization of the present invention (Claim 2),
The vulcanized tire cooling device according to claim 1, wherein the wind direction of the plurality of air blowing means is set to have a certain angle from a radial line passing through the center of the vulcanized tire.

又、本発明（請求項３）の加硫後タイヤ冷却装置は、
請求項１又は請求項２記載の加硫後タイヤ冷却装置において、複数個の送風手段が前記筒状フードの上下方向に１段又は複数段に配設されている構成とした。 Further, the tire cooling device after vulcanization of the present invention (Claim 3) is:
In vulcanized tire cooling apparatus according to claim 1 or claim 2, wherein, also 1 stage a plurality of blowing means in the vertical direction of the cylindrical hood has a configuration which is arranged in several stages double.

本発明の加硫後タイヤ冷却装置は、加硫後タイヤの外周を全周に亘って囲むように筒状フードを配置した構成に特徴がある。
このような筒状フードを設けることにより、送風手段によって加硫後タイヤの外周面に吹き付けられた冷却媒体としての風は、外方に逃げるのを筒状フードによって遮られ、筒状フードと加硫後タイヤの外周面の間で反射しながら環状空隙内で拡散していく。
このように加硫後タイヤの外周面の回りに風の層ができるため、加硫後タイヤの外周面に風が満遍なく行き渡るようになり、よって均一な冷却を促すと共に冷却時間を短縮させることができる。 The post-vulcanized tire cooling device of the present invention is characterized by a configuration in which a cylindrical hood is arranged so as to surround the outer periphery of the post-vulcanized tire over the entire circumference.
By providing such a cylindrical hood, the wind as the cooling medium blown to the outer peripheral surface of the tire after vulcanization by the blowing means is blocked by the cylindrical hood from escaping outward, and the cylindrical hood and the hood are heated. It diffuses in the annular gap while reflecting between the outer peripheral surfaces of the tire after vulcanization.
In this way, a wind layer is formed around the outer peripheral surface of the vulcanized tire, so that the wind is evenly distributed on the outer peripheral surface of the tire after vulcanization, thereby facilitating uniform cooling and shortening the cooling time. it can.

又、加硫後タイヤから発生した油煙についても、筒状フードによって外方への放散を遮ることができるため、油煙が周辺の部品等に付着し、これらを汚損させたり、動作不良を生じさせたりするといった不具合を解消できる。 In addition, oil smoke generated from tires after vulcanization can be blocked by the cylindrical hood, so that oil smoke adheres to surrounding parts, causing them to become dirty or malfunction. Can solve problems such as.

また、送風手段としては、送風ファンを用いる。
送風ファンを用いると、環状送気管のノズル口からの送風に比べて送風範囲を広く取ることができ、極めて局部的な送風を回避できるし、ノズル口から圧縮空気を噴出させる環状送気管に比べてランニングコストが安くなる。 A blower fan is used as the blower .
When using a blower fan, it is possible to widen the air blowing range compared to blowing from the nozzle port of the annular air supply pipe, and it is possible to avoid extremely local blowing, and compared to the annular air supply pipe that ejects compressed air from the nozzle opening Running costs are reduced.

又、複数個の送風手段の風向方向を、加硫後タイヤの中心を通る半径線から一定の角度を持つように設定させると（請求項２）、環状空隙に生じた風の層を加硫後タイヤの外周に沿って一定方向に流動させることができる。
これにより、より一層に加硫後タイヤの外周面に風を満遍なく行き渡らせることができる。 Further, when the direction of wind of the plurality of air blowing means is set to have a certain angle from the radial line passing through the center of the tire after vulcanization (Claim 2 ), the wind layer generated in the annular gap is vulcanized. It can be made to flow in a certain direction along the outer periphery of the rear tire.
As a result, the wind can be evenly distributed over the outer peripheral surface of the tire after vulcanization.

又、複数個の送風手段は、筒状フードの上下方向に１段又は複数段に配設させることができる（請求項３）。
特に、送風手段を筒状フードの上下方向に複数段に配設させると、加硫後タイヤのトレッド部、ショルダー部、ビード部に至るまで、加硫後タイヤのタイヤ幅方向に満遍なく風を行き渡らせることができる。 Further, a plurality of blowing means are also one step in the vertical direction of the cylindrical hood can be arranged in several stages double (claim 3).
In particular, when the air blowing means is arranged in a plurality of stages in the vertical direction of the cylindrical hood, the wind is evenly distributed in the tire width direction of the vulcanized tire from the tread portion, the shoulder portion, and the bead portion of the vulcanized tire.

これにより、環状空隙Ｓに生じた風の層を加硫後タイヤの外周に沿って一定方向（矢印Ｂ方向）に流動させることができる。
尚、前期角度θは、環状空隙Ｓの間隔や送風ファン４による風速等に応じて適宜に設定するものである。 The plurality of blower fans 4 have a radial line R between the radial line R passing through the center C of the vulcanized tire 1 and the tangent line K to the outer periphery of the vulcanized tire 1 in the air direction (arrow A direction). Is set to have a certain angle θ.
Thereby, the wind layer generated in the annular gap S can be made to flow in a certain direction (arrow B direction) along the outer periphery of the tire after vulcanization.
