Description

アンローディング装置およびこれを備えたタイヤ加硫機、並びに、加硫済タイヤの製造方法およびアンローディング装置の改造方法Unloading device, tire vulcanizer equipped with the same, and method of manufacturing vulcanized tire and method of modifying unloading device
　本発明は、アンローディング装置およびこれを備えたタイヤ加硫機、並びに、加硫済タイヤの製造方法およびアンローディング装置の改造方法に関する。 The present invention relates to an unloading device, a tire vulcanizer equipped with the same, and a method of manufacturing a vulcanized tire and a method of modifying the unloading device.
　タイヤ加硫機によってタイヤを加硫すると、加硫容器を開いた後に加硫済タイヤから油煙が発生する。油煙は、近年特に高まっている環境規制や機械保全の観点から回収することが望ましい。 When a tire is vulcanized by a tire vulcanizer, oil smoke is generated from the vulcanized tire after the vulcanizing container is opened. It is desirable to recover oil smoke from the viewpoint of environmental regulation and machine maintenance which are particularly increasing in recent years.
　特許文献１には、加硫容器を開いた後に加硫容器内の気体を吸引することによって油煙を回収する装置が開示されている。 Patent Document 1 discloses an apparatus for recovering oil smoke by suctioning a gas in a vulcanization vessel after opening the vulcanization vessel.
特許第５６９４９３２号公報Patent No. 5694932 gazette
　特許文献１では、加硫済タイヤが金型やブラダから離れた際に発生する油煙を回収するために、加硫容器を開いた直後に気体を吸引するものである。 In patent document 1, in order to collect | recover the oil smoke which generate | occur | produces when a vulcanized tire remove | deviates from a metal mold | die or a bladder, gas is attracted | sucked immediately after opening a vulcanization container.
　本発明者等は、油煙の発生状況について検討したところ、加硫容器を開いた直後よりも、金型内に位置する加硫済タイヤからブラダを引きはがす、或いはアンローディング装置で加硫済タイヤを取り出す工程で多くの油煙が発生することが分かった。 The present inventors examined the generation of oil smoke and found that the bladder was peeled off from the vulcanized tire positioned in the mold immediately after opening the vulcanizing container, or the vulcanized tire was removed by an unloading device. It was found that a lot of oil smoke was generated in the process of taking out.
　このような事情に鑑みてなされたものであって、本開示は、加硫済タイヤから発生する油煙を効果的に吸引することを目的とする。 The present disclosure has been made in view of such circumstances, and an object of the present disclosure is to effectively suck oil smoke generated from a vulcanized tire.
　本発明の一態様に係るアンローディング装置は、加硫機本体の型で加硫された加硫済タイヤを該型の上方から掴んで支持する支持部と、前記支持部の上方に設けられたカバー部と、該カバー部の下方空間を吸引する吸引装置とを備えている。 An unloading device according to one aspect of the present invention is provided with a support portion for gripping and supporting a vulcanized tire vulcanized by a mold of a vulcanizer main body from above the mold, and provided above the support portion A cover portion and a suction device for suctioning a space under the cover portion are provided.
　油煙の発生状況について検討したところ、型でタイヤを加硫して型を開いた直後よりも、型内に位置する加硫済タイヤからブラダを引きはがす、或いはアンローディング装置で加硫済タイヤを取り出す工程で多くの油煙が発生することが分かった。そこで、加硫済タイヤを型の上方から掴んで支持する支持部の上方にカバー部を設け、カバー部の下方空間を吸引装置によって吸引することとした。これにより、カバー部の下方に位置する加硫済タイヤから発生する油煙を効果的に吸引することができる。 The situation of the generation of oil smoke was examined, and the bladder was peeled off from the vulcanized tire located in the mold immediately after the mold was vulcanized and the mold was opened, or the vulcanized tire was unloaded by an unloading device. It was found that a large amount of oil smoke was generated during the removal step. Therefore, the cover portion is provided above the support portion for gripping and supporting the vulcanized tire from above the mold, and the space below the cover portion is sucked by the suction device. Thus, oil smoke generated from the vulcanized tire located below the cover portion can be effectively sucked.
　本発明の一態様に係るアンローディング装置では、前記カバー部の平面視中央部には、上方に向けて開くことができる蓋部が設けられている。 In the unloading device according to one aspect of the present invention, a lid portion that can be opened upward is provided at a central portion in a plan view of the cover portion.
　カバー部の平面視中央部に、上方に向けて開くことができる蓋部を設けることとした。この蓋部は、平面視中央部に設けられているので、加硫機本体に設けられた中心機構の上端に当接する位置に設けられ、中心機構の上端に当接した場合に上方に開く。このように中心機構の上部がカバー部を貫通できるので、カバー部の高さを、中心機構を収容できる高さとする必要はない。したがって、カバー部の高さを低くすることでタイヤ加硫機の全高を高く見直す必要が無い。
　特に、中心機構が、加硫済タイヤに固着したブラダを加硫タイヤから取り外す際に上昇する動作を行う場合には、中心機構が上昇する前に（換言すると中心機構の上昇の完了を待たずに）アンローディング装置を中心機構の上方に位置させることができるので、サイクルタイムを短縮することができる。
　また、蓋部に外力が働かない場合は閉状態となるように、蓋部を閉方向に付勢する付勢手段（バネなど）を設けることが好ましい。
　さらには、蓋部を開いた時に油煙がアンローディング装置上方へ逃げることを防ぐために、蓋開口部を上下に伸縮可能な蛇腹等で密封することも可能である。 A lid portion that can be opened upward is provided at a central portion in plan view of the cover portion. The lid portion is provided at the central portion in plan view, and thus is provided at a position abutting on the upper end of the central mechanism provided on the vulcanizer main body, and opens upward when abutting on the upper end of the central mechanism. Since the upper portion of the central mechanism can penetrate the cover in this manner, the height of the cover does not have to be the height that can accommodate the central mechanism. Therefore, it is not necessary to review the entire height of the tire vulcanizer high by lowering the height of the cover portion.
In particular, when the central mechanism performs an operation to ascend when removing the bladder fixed to the vulcanized tire from the vulcanized tire, before the central mechanism ascends (in other words, it waits for completion of the central mechanism to rise). ) The cycle time can be reduced since the unloading device can be located above the central mechanism.
Further, it is preferable to provide biasing means (spring or the like) for biasing the lid in the closing direction so that the lid is closed when no external force is exerted.
Furthermore, in order to prevent oil smoke from escaping above the unloading device when the lid is opened, it is possible to seal the lid opening with a bellows or the like that can be extended and retracted.
　本発明の一態様に係るアンローディング装置では、前記吸引装置を制御する制御部を備え、前記制御部は、前記加硫機本体の外方の所定位置に該加硫済タイヤを載置した後の所定期間にわたって、前記吸引装置による吸引を行う。 The unloading device according to an aspect of the present invention includes a control unit that controls the suction device, and the control unit is configured to set the vulcanized tire at a predetermined position on the outer side of the vulcanizer main body. The suction device performs suction for a predetermined period of time.
　アンローディング装置によって加硫済タイヤを加硫機本体の外方に移動させた後にも、加硫済タイヤから油煙が発生することが分かった。そこで、加硫機本体の外方の所定位置に加硫済タイヤを載置した後の所定期間にわたって油煙を吸引することで、加硫機外部で飛散している油煙も回収することを可能とした。
　なお、吸引制御は加硫済タイヤのアンローディング前から加硫機外方への載置後の所定期間まで連続吸引しても良いし、アンローディング時のみあるいは加硫済タイヤを所定位置に載置する所定期間で吸引しても良い。 It was found that oil smoke was generated from the vulcanized tire even after the vulcanized tire was moved outward of the vulcanizer main body by the unloading device. Therefore, by sucking oil smoke over a predetermined period after placing the vulcanized tire at a predetermined position on the outer side of the vulcanizer main body, it is possible to collect oil smoke scattered outside the vulcanizer. did.
Suction control may be continuous suction from unloading before unloading of the vulcanized tire to a predetermined period after mounting on the outer side of the vulcanizer, or only at unloading or placing the vulcanized tire at a predetermined position. Suction may be performed for a predetermined period of time.
　本発明の一態様に係るアンローディング装置では、前記カバー部には、前記下方空間の周囲を包囲するように下方に向けてガスを噴出するガス噴出部が設けられている。 In the unloading device according to one aspect of the present invention, the cover portion is provided with a gas ejection portion which ejects gas downward so as to surround the periphery of the lower space.
　下方空間の周囲を包囲するように下方に向けてガスを噴出するガス噴出部をカバー部に設けることとしたので、加硫済タイヤから放出される油煙を下方空間内に留めることができる。 Since the cover portion is provided with the gas ejection portion for ejecting gas downward so as to surround the periphery of the lower space, oil smoke emitted from the vulcanized tire can be retained in the lower space.
　本発明の一態様に係るタイヤ加硫機は、型内でタイヤを加硫する加硫機本体と、上記のいずれかのアンローディング装置と、を備えている。 A tire vulcanizer according to an aspect of the present invention includes a vulcanizer main body that vulcanizes a tire in a mold, and any one of the above-described unloading devices.
　上記のアンローディング装置を備えているので、加硫済タイヤから発生する油煙を効果的に吸引することができる。 Since the above-described unloading device is provided, oil smoke generated from the vulcanized tire can be effectively sucked.
　本発明の一態様に係る加硫済タイヤの製造方法は、加硫機本体の型で加硫された加硫済タイヤを該型の上方から掴んで支持する支持部と、前記支持部の上方に設けられたカバー部と、を備えたアンローディング装置を用いた加硫済タイヤの製造方法であって、前記型から前記加硫済タイヤを前記支持部によって支持するときに、前記カバー部の下方空間を吸引する。 According to one aspect of the present invention, there is provided a method of manufacturing a vulcanized tire, comprising: a support portion for gripping and supporting a vulcanized tire vulcanized by a mold of a vulcanizer main body from above the mold; A method of manufacturing a vulcanized tire using an unloading device including a cover portion provided on the cover portion, wherein the vulcanized tire is supported by the support portion from the mold; Aspirate the lower space.
　油煙の発生状況について検討したところ、型でタイヤを加硫して型を開いた直後よりも、型内に位置する加硫済タイヤからブラダを引きはがす、或いはアンローディング装置で加硫済タイヤを取り出すタイミングで多くの油煙が発生することが分かった。そこで、加硫済タイヤを型の上方から掴んで支持する支持部の上方にカバー部を設け、カバー部の下方空間を吸引することとした。これにより、カバー部の下方に位置する加硫済タイヤから発生する油煙を効果的に吸引することができる。 The situation of the generation of oil smoke was examined, and the bladder was peeled off from the vulcanized tire located in the mold immediately after the mold was vulcanized and the mold was opened, or the vulcanized tire was unloaded by an unloading device. It was found that a lot of oil smoke was generated at the timing of taking out. Therefore, the cover portion is provided above the support portion for gripping and supporting the vulcanized tire from above the mold, and the space below the cover portion is sucked. Thus, oil smoke generated from the vulcanized tire located below the cover portion can be effectively sucked.

　以下に、本発明にかかる一実施形態について、図面を参照して説明する。
　図１には、タイヤ加硫機１が示されている。タイヤ加硫機１は、加硫機本体２と、アンローディング装置３とを備えている。 Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
A tire vulcanizer 1 is shown in FIG. The tire vulcanizer 1 includes a vulcanizer main body 2 and an unloading device 3.
　加硫機本体２は、金型（型）４を備えている。金型４は、上下方向に立設された４本のフレーム５の間に設置されている。各フレーム５は、図２に示すように、平面視した場合に四角形の下板６ａ及び上板６bの両側面に配置されている。金型４は、内部にてタイヤを高温高圧下で加硫する加硫容器とされている。金型４は、下型４ａと上型４ｂとを備えている。下型４ａは、フレーム５の下方に配置された下板６ａに固定されている。上型４ｂは、下型４ａに対して接近離間するように上下方向に移動可能な上板６ｂに固定されている。 The vulcanizer body 2 is provided with a mold 4. The mold 4 is installed between four frames 5 erected in the vertical direction. As shown in FIG. 2, each of the frames 5 is disposed on both side surfaces of the lower plate 6 a and the upper plate 6 b of the square in a plan view. The mold 4 is a vulcanizing container for vulcanizing the tire under high temperature and high pressure inside. The mold 4 comprises a lower mold 4a and an upper mold 4b. The lower mold 4 a is fixed to a lower plate 6 a disposed below the frame 5. The upper mold 4b is fixed to an upper plate 6b movable in the vertical direction so as to approach and separate from the lower mold 4a.
　図１は、下型４ａと上型４ｂとが接近して金型４が閉じた状態である。この状態では、アンローディング装置３は、図２に示すように、加硫機本体２の外方、具体的にはタイヤコンベア７の上方に位置している。 In FIG. 1, the lower mold 4a and the upper mold 4b are close to each other, and the mold 4 is closed. In this state, as shown in FIG. 2, the unloading device 3 is located outside the vulcanizer main body 2, specifically, above the tire conveyor 7.
　アンローディング装置３は、加硫済タイヤを掴んで支持する支持部１０を備えている。支持部１０は、タイヤの径方向に移動可能とされた複数の爪部を有しており、これら爪部がタイヤの内周縁を係止することによってタイヤを掴むようになっている。アンローディング装置３は、上方から下方へ移動してタイヤを掴む。 The unloading device 3 includes a support 10 for gripping and supporting a vulcanized tire. The support portion 10 has a plurality of claws movable in the radial direction of the tire, and these claws grip the tire by engaging the inner peripheral edge of the tire. The unloading device 3 moves downward from above to grip the tire.
　アンローディング装置３は、支持部１０の上方に、カバー部１１を備えている。カバー部１１は、略円筒形状のカバー本体１１ａと、カバー本体１１ａの下部に接続されたフード部１１ｂとを備えている。フード部１１ｂは、カバー本体１１ａから下方に向かって外方に広がる円錐形とされている。フード部１１ｂの外径は、タイヤの外径以上の大きさとされている。 The unloading device 3 includes a cover 11 above the support 10. The cover portion 11 includes a substantially cylindrical cover main body 11 a and a hood portion 11 b connected to the lower portion of the cover main body 11 a. The hood portion 11b is formed in a conical shape that spreads outward from the cover main body 11a downward. The outer diameter of the hood portion 11 b is equal to or larger than the outer diameter of the tire.
　アンローディング装置３は、スイングアーム１２を備えている。スイングアーム１２によって、支持部１０及びカバー部１１は、加硫機本体２の外側の所定位置を支点Ｏ１（図２及び図４参照）として揺動する。 The unloading device 3 includes a swing arm 12. By the swing arm 12, the support portion 10 and the cover portion 11 swing with a predetermined position on the outside of the vulcanizer main body 2 as a fulcrum O1 (see FIGS. 2 and 4).
　図３には、上型４ｂが上方に移動した状態、即ち金型４が開いた状態が示されている。この状態では、アンローディング装置３の支持部１０が下型４ａと上型４ｂとの間でかつ、加硫済タイヤＴの上方に位置している。支持部１０及びカバー部１１は、図示しない制御部の指示によって、金型４上方の加硫済タイヤ取出位置（図３及び図４参照）と、加硫済タイヤ冷却位置（図１及び図２参照）となるタイヤコンベア７の上方との間を往復動する。 FIG. 3 shows a state in which the upper mold 4b has moved upward, that is, a state in which the mold 4 is opened. In this state, the support portion 10 of the unloading device 3 is located between the lower mold 4 a and the upper mold 4 b and above the vulcanized tire T. The supporting unit 10 and the cover unit 11 are instructed by the control unit (not shown) to take out the vulcanized tire take-out position above the mold 4 (see FIGS. 3 and 4) and the vulcanized tire cooling position (see FIGS. 1 and 2). Reciprocate between the upper part of the tire conveyor 7 to be referred to.
　図１～図４に示すように、アンローディング装置３のカバー本体１１ａには、吸引装置１５が取り付けられている。吸引装置１５は、カバー本体１１ａに上流端が接続された吸引配管１５ａと、吸引配管１５ａの下流端が接続された吸引ファン１５ｂとを備えている。吸引ファン１５ｂは、図示しない制御部によって起動及び停止が制御される。吸引ファン１５ｂを動作することによって、吸引配管１５ａを介してカバー部１１内、より具体的にはフード部１１ｂの下方空間の気体ないし油煙が吸引される。 As shown in FIGS. 1 to 4, a suction device 15 is attached to the cover main body 11 a of the unloading device 3. The suction device 15 includes a suction pipe 15a whose upstream end is connected to the cover body 11a, and a suction fan 15b whose downstream end is connected. The suction fan 15 b is controlled to start and stop by a control unit (not shown). By operating the suction fan 15b, gas or oil smoke in the space inside the cover portion 11, more specifically, in the lower space of the hood portion 11b is sucked through the suction pipe 15a.
　カバー部１１の上部すなわちカバー本体１１ａの上端の平面視中央部には、カバー本体１１ａの上端に形成された開口を塞ぐ蓋部１１ｃが設けられている。蓋部１１ｃは、図１の破線で示すように、一端をヒンジとして上方に回動して開くことができるようになっている。蓋部１１ｃは、バネ等の弾性部材によって閉方向に付勢されており、所定値以上の外力が加わらない限り開かずに閉状態となるようになっている。 A lid portion 11c is provided at the upper portion of the cover portion 11, that is, in the central portion in plan view of the upper end of the cover main body 11a, for closing an opening formed at the upper end of the cover main body 11a. The lid portion 11c can be opened upward by pivoting upward as one end thereof is a hinge as shown by a broken line in FIG. The lid portion 11c is biased in the closing direction by an elastic member such as a spring, and is closed without opening unless an external force equal to or greater than a predetermined value is applied.
　図３に示すように、金型４の中心軸線に沿って立設する中心機構１７が設けられている。中心機構１７は、ブラダＢを備えている。ブラダＢは、タイヤの内面を押圧した状態で、加熱および加圧して加硫処理を行うために用いられる。図３では、ブラダＢが膨張して加硫済タイヤＴの内面に固着している状態を示している。中心機構１７は、制御部の指令によって、ブラダＢとともに上下方向に伸張および短縮が可能とされている。中心機構１７が上方に伸張することによって、加硫済タイヤＴの内面に固着したブラダＢが取り外されるようになっている（図５Ｃ参照）。 As shown in FIG. 3, a central mechanism 17 is provided to stand along the central axis of the mold 4. The central mechanism 17 includes a bladder B. The bladder B is used to heat and pressurize the rubber while the inner surface of the tire is pressed. In FIG. 3, the state which the bladder B expand | swells and adheres to the inner surface of the vulcanized tire T is shown. The central mechanism 17 can be extended and shortened in the vertical direction together with the bladder B by an instruction of the control unit. By expanding the central mechanism 17 upward, the bladder B fixed to the inner surface of the vulcanized tire T is removed (see FIG. 5C).
　タイヤ加硫機１は、タイヤを加硫する各工程における動作を制御する制御部を備えている。制御部は、例えば、ＣＰＵ（Central　Processing　Unit）、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、及びコンピュータ読み取り可能な記憶媒体等から構成されている。そして、各種機能を実現するための一連の処理は、一例として、プログラムの形式で記憶媒体等に記憶されており、このプログラムをＣＰＵがＲＡＭ等に読み出して、情報の加工・演算処理を実行することにより、各種機能が実現される。なお、プログラムは、ＲＯＭやその他の記憶媒体に予めインストールしておく形態や、コンピュータ読み取り可能な記憶媒体に記憶された状態で提供される形態、有線又は無線による通信手段を介して配信される形態等が適用されてもよい。コンピュータ読み取り可能な記憶媒体とは、磁気ディスク、光磁気ディスク、ＣＤ－ＲＯＭ、ＤＶＤ－ＲＯＭ、半導体メモリ等である。 The tire vulcanizer 1 includes a control unit that controls the operation in each step of vulcanizing the tire. The control unit is configured of, for example, a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), a computer readable storage medium, and the like. Then, a series of processes for realizing various functions are stored in the form of a program, for example, in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing and arithmetic processing. Thus, various functions are realized. The program may be installed in advance in a ROM or other storage medium, may be provided as stored in a computer-readable storage medium, or may be distributed via a wired or wireless communication means. Etc. may be applied. The computer readable storage medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory or the like.
　次に、タイヤをアンローディングする工程について説明する。なお、以下の各工程は、制御部の指示によって行われる。 Next, the process of unloading the tire will be described. The following steps are performed according to an instruction from the control unit.
　図５Ａは、タイヤを加硫した後で金型４が閉じた状態が示されている。この状態は、図１及び図２と同様である。 FIG. 5A shows the mold 4 closed after vulcanizing the tire. This state is the same as in FIG. 1 and FIG.
　そして、図５Ｂに示すように、上型４ｂが上昇して金型４が開く。図５Ｂの状態は、図３及び図４と同様である。アンローディング装置３に干渉しない高さまで上型４ｂが上昇すると、上型４ｂの上昇途中で、アンローディング装置３が中心機構１７の直上まで移動する。このとき、中心機構１７は、上方に伸張せずに下方に位置した状態とされている。図５Ｂの状態に至るまでに、吸引装置１５が起動し、フード部１１ｂの下方空間の吸引が開始される。したがって、アンローディング装置３が加硫済タイヤＴの上方に位置したときには、加硫済タイヤＴから発生する油煙が吸引される。吸引装置１５による油煙の吸引は、以降の工程においても継続して行われる。 Then, as shown in FIG. 5B, the upper mold 4b is raised and the mold 4 is opened. The state of FIG. 5B is the same as that of FIGS. 3 and 4. When the upper die 4 b is lifted to a height not interfering with the unloading device 3, the unloading device 3 moves to a position just above the central mechanism 17 while the upper die 4 b is lifted. At this time, the central mechanism 17 is in a state of being positioned downward without extending upward. By the time the state of FIG. 5B is reached, the suction device 15 is activated, and suction in the space below the hood portion 11b is started. Therefore, when the unloading device 3 is positioned above the vulcanized tire T, the oil smoke generated from the vulcanized tire T is sucked. The suction of oil smoke by the suction device 15 is continuously performed also in the subsequent steps.
　そして、図５Ｃに示すように、中心機構１７が上方に伸張する。これにより、加硫済タイヤＴからブラダＢが取り外される。このタイミングにおいても上型４ｂが上昇し続けている。 Then, as shown in FIG. 5C, the central mechanism 17 extends upward. Thereby, the bladder B is removed from the vulcanized tire T. The upper mold 4b continues to rise at this timing as well.
　そして、図５Ｄに示すように、上型４ｂの上昇が終了するタイミングでは既に、アンローディング装置３の支持部１０及びカバー部１１が下降し、支持部１０が加硫済タイヤＴの内周縁を係止する。このとき、カバー部１１の蓋部１１ｃが中心機構１７の上端に接触することによって開く。蓋部１１ｃが開いても、吸引装置１５によって吸引が継続して行われているので、油煙が開口から放出されることは殆どない。 Then, as shown in FIG. 5D, at the timing when the lifting of the upper mold 4b is finished, the support portion 10 and the cover portion 11 of the unloading device 3 have already been lowered, and the support portion 10 is the inner peripheral edge of the vulcanized tire T. Lock it. At this time, the cover 11 c of the cover 11 is opened by contacting the upper end of the central mechanism 17. Even if the lid portion 11 c is opened, since the suction is continuously performed by the suction device 15, oil smoke is hardly emitted from the opening.
　そして、図５Ｅに示すように、アンローディング装置３が上昇し、支持部１０で加硫済タイヤＴを掴んだまま持ち上げる。このとき、上型４ｂは上昇完了位置にて停止されている。 Then, as shown in FIG. 5E, the unloading device 3 ascends and lifts the vulcanized tire T while holding it by the support portion 10. At this time, the upper mold 4b is stopped at the rising completion position.
　その後、図５Ｆに示すように、アンローディング装置３が中心機構１７の上方から退避し、図５Ｇ及び図５Ｈに示すように、タイヤコンベア７（図４参照）上に加硫済タイヤＴを載置する。そして、次ステップで図示しない加硫前タイヤが配置された後、図５Ｉに示すように、上型４ｂを下降させ、金型４を閉じる動作を開始する。図５Ｈ及び図５Ｉに示すように、加硫済タイヤＴを加硫機本体２から取り出した後であっても、所定期間にわたって、タイヤコンベア７上の加硫済タイヤＴの上方にカバー部１１を位置させた状態で吸引装置１５によって油煙を吸引し続ける。 Thereafter, as shown in FIG. 5F, the unloading device 3 retracts from above the central mechanism 17, and as shown in FIGS. 5G and 5H, the vulcanized tire T is loaded on the tire conveyor 7 (see FIG. 4). Place. Then, after the tire before vulcanization is placed in the next step, as shown in FIG. 5I, the upper mold 4 b is lowered to start the operation of closing the mold 4. As shown in FIGS. 5H and 5I, even after the vulcanized tire T is taken out of the vulcanizer main body 2, the cover portion 11 is provided above the vulcanized tire T on the tire conveyor 7 for a predetermined period. In the state in which the is placed, suction of oil smoke is continued by the suction device 15.
　以上の通り、本実施形態によれば以下の作用効果を奏する。 As described above, according to this embodiment, the following effects can be obtained.
　油煙の発生状況について検討したところ、金型４でタイヤを加硫して金型４を開いた直後よりも、金型４内に位置する加硫済タイヤＴからブラダＢを引きはがす、或いはアンローディング装置３で加硫済タイヤＴを取り出す工程で多くの油煙が発生することが分かった。そこで、加硫済タイヤＴを金型４の上方から掴んで支持する支持部１０の上方にカバー部１１を設け、カバー部１１の下方空間を吸引装置１５によって油煙を吸引することとした。これにより、カバー部１１の下方に位置する加硫済タイヤＴから発生する油煙を効果的に吸引することができる。 The situation of generation of oil smoke was examined, and the bladder B was peeled off from the vulcanized tire T located in the mold 4 rather than immediately after the tire was vulcanized with the mold 4 and the mold 4 was opened, or It was found that a large amount of oil smoke was generated in the step of taking out the vulcanized tire T by the loading device 3. Therefore, the cover portion 11 is provided above the support portion 10 for gripping and supporting the vulcanized tire T from above the mold 4, and the suction device 15 sucks oil smoke in the space below the cover portion 11. Thus, oil smoke generated from the vulcanized tire T located below the cover portion 11 can be effectively sucked.
　カバー部１１の平面視中央部の上端に、上方に向けて開くことができる蓋部１１ｃを設けることとした。この蓋部１１ｃは、平面視中央部に設けられているので、加硫機本体２に設けられた中心機構１７の上端に当接する位置に設けられ、中心機構１７の上端に当接した場合に上方に開く（図５Ｄ参照）。このように中心機構１７の上部がカバー部１１を貫通できるので、カバー部１１の高さを、中心機構１７を収容できる高さとする必要はない。したがって、カバー部１１の高さを低くすることができるので、タイヤ加硫機の全高を高く見直す必要が無く、加硫機本体構造のコストアップや生産性を損ねることはない。 At the upper end of the central portion of the cover 11 in a plan view, a lid 11 c that can be opened upward is provided. Since the lid portion 11 c is provided at the central portion in a plan view, the lid portion 11 c is provided at a position to abut on the upper end of the central mechanism 17 provided on the vulcanizer main body 2 and abuts on the upper end of the central mechanism 17. Open upwards (see FIG. 5D). As described above, since the upper portion of the central mechanism 17 can penetrate the cover portion 11, the height of the cover portion 11 does not have to be the height that can accommodate the central mechanism 17. Therefore, since the height of the cover portion 11 can be reduced, there is no need to review the entire height of the tire vulcanizer high, and the cost increase of the vulcanizer main body structure and the productivity are not impaired.
　加硫済タイヤＴに固着したブラダＢを加硫済タイヤＴから取り外す際に中心機構１７が上方に伸張する。このとき、カバー部１１に蓋部１１ｃが設けられているので、中心機構１７の上昇によるカバー部１１との干渉を考慮する必要がない。したがって、中心機構１７が上昇する前に（換言すると中心機構１７の上昇の完了を待たずに）、アンローディング装置３を中心機構１７の上方に位置させることができる（図５Ｂ参照）。これにより、タイヤを加硫する際のサイクルタイムを短縮することができる。 When the bladder B fixed to the vulcanized tire T is removed from the vulcanized tire T, the central mechanism 17 extends upward. At this time, since the cover 11 c is provided in the cover 11, it is not necessary to consider the interference with the cover 11 due to the ascent of the central mechanism 17. Therefore, the unloading device 3 can be positioned above the central mechanism 17 before the central mechanism 17 is lifted (in other words, without waiting for the completion of the lifting of the central mechanism 17) (see FIG. 5B). Thereby, the cycle time at the time of vulcanizing a tire can be shortened.
　また、開閉可能な蓋部１１ｃを設けることによって、中心機構１７の上昇高さに関わらず支持部１０を加硫済タイヤＴの近くの高さに位置させることができるので、支持部１０の下降ストロークを短くすることができ、さらにサイクルタイムを短縮することができる。 Further, by providing the lid 11c which can be opened and closed, the support 10 can be positioned at a height near the vulcanized tire T regardless of the elevation height of the central mechanism 17, so the descent of the support 10 The stroke can be shortened, and the cycle time can be further shortened.
　蓋部１１ｃに外力が働かない場合は閉状態となるように、蓋部１１ｃを閉方向に付勢する付勢手段を設けることとした。これにより、中心機構１７の上端に接触して開とされる場合のほかは常に蓋部１１ｃが閉じられていることになり、油煙を効果的に吸引することができる。
　或いは、蓋部１１ｃ開時にわずかではあるが油煙がアンローディング装置３上方へ逃げることを防ぐために、蓋開口部を上下に伸縮可能な蛇腹等で密封し更に吸引効率を向上させることも可能である。 An urging means is provided to urge the lid portion 11c in the closing direction so that the lid portion 11c is closed when no external force acts on the lid portion 11c. As a result, the lid 11 c is always closed except when it is opened in contact with the upper end of the central mechanism 17, and oil smoke can be effectively sucked.
Alternatively, in order to prevent oil smoke from escaping to the upper side of the unloading device 3 although it is slightly when the lid 11c is opened, it is possible to seal the lid opening with upper and lower expandable bellows and further improve suction efficiency. .
　アンローディング装置３によって加硫済タイヤＴを加硫機本体２の外方に移動させた後にも（図５Ｈ及び図５Ｉ参照）、加硫済タイヤＴから油煙が発生することが分かった。そこで、加硫機本体２の外方の所定位置（例えばタイヤコンベア７上）に加硫済タイヤＴを載置した後の所定期間にわたって油煙を吸引することによって、油煙を効果的に吸引することができる。 Also after moving the vulcanized tire T to the outside of the vulcanizer main body 2 by the unloading device 3 (see FIGS. 5H and 5I), it was found that oil smoke was generated from the vulcanized tire T. Therefore, oil smoke can be effectively sucked by suctioning oil smoke over a predetermined period after the vulcanized tire T is placed at a predetermined position (for example, on the tire conveyor 7) outside the vulcanizer main body 2 Can.
　なお、本実施形態は以下のように変形することができる。
　例えば、図６に示すように、フード部１１ｂの外周縁に沿ってエア（ガス）を下方に噴出するノズル（ガス噴出部）２０を設けても良い。ノズル２０は、図７に示すように、円管をリング状に曲成し、下方に複数の噴出孔２０ａを設けた構成とされている。ノズル２０には空気供給管２１が接続されており、空気供給管２１を介して図示しないコンプレッサからエアが供給される。
　なお、ガス噴出部形状は丸孔２０ａに限らず、例えば図示しないスリット形状とすることで広範囲な噴出機能を持たせることができる。 The present embodiment can be modified as follows.
For example, as shown in FIG. 6, a nozzle (gas ejection part) 20 may be provided which ejects air (gas) downward along the outer peripheral edge of the hood part 11b. As shown in FIG. 7, the nozzle 20 is formed by bending a circular pipe in a ring shape, and providing a plurality of ejection holes 20 a at the lower side. An air supply pipe 21 is connected to the nozzle 20, and air is supplied from a compressor (not shown) via the air supply pipe 21.
In addition, the gas ejection part shape is not limited to the round hole 20a, and for example, a wide range of ejection functions can be provided by using a slit shape (not shown).
　このようにノズル２０を設けることで、図８に示すように、矢印Ａ１方向にエアを噴出させて加硫済タイヤＴを包囲するようにエアカーテンを形成し、加硫済タイヤＴから放出される油煙を下方空間内に留めて効果的に吸引することができる。
　なお、図示しないが、ガス噴出部を設ける代わりにフード１１ｂ外周縁下端からタイヤ支持部１０下端まで更に円筒状カバーを設けることで油煙を前述同様に下方空間に留めることも可能である。この場合も、アンローディング装置３の高さに影響を及ぼすことはなくタイヤ加硫機の全高を高く見直す必要が無い。 By providing the nozzle 20 in this manner, as shown in FIG. 8, an air curtain is formed so as to blow air in the direction of arrow A1 to surround the vulcanized tire T, and is released from the vulcanized tire T. Oil smoke can be trapped in the lower space and effectively aspirated.
Although not shown, oil smoke can be retained in the lower space as described above by further providing a cylindrical cover from the lower end of the outer peripheral edge of the hood 11b to the lower end of the tire support 10 instead of providing the gas jet portion. Also in this case, the height of the unloading device 3 is not affected, and it is not necessary to review the entire height of the tire vulcanizer high.
　また、本実施形態は、アンローディング装置の改造方法にも用いることができる。具体的には、支持部１０を備えたアンローディング装置に対して、支持部１０の上方にカバー部１１を設け、かつ、カバー部１１の下方空間を吸引する吸引装置１５を設ける改造を施す。これにより、既存のアンローディング装置に対して油煙を効果的に吸引できるように改造することができ、蓋部１１ｃの開閉構造により加硫機全高を改造する必要はない。 Moreover, this embodiment can be used also for the remodeling method of an unloading apparatus. Specifically, the unloading device provided with the support portion 10 is modified by providing the cover portion 11 above the support portion 10 and providing the suction device 15 for suctioning the space below the cover portion 11. As a result, the existing unloading device can be remodeled to be able to suck oil smoke effectively, and there is no need to remodel the full height of the vulcanizer by the opening and closing structure of the lid portion 11c.
