Description
本発明は、球状容器や湾曲底部を有する筒状容器、例えば石英ガラスルツボ等を安定に吊り上げることができ、かつ容器への装着および取り外しが容易な吊り具に関する。 The present invention relates to a hanger that can stably suspend a spherical container or a cylindrical container having a curved bottom, such as a quartz glass crucible, and can be easily attached to and detached from the container.
石英ガラスルツボを搬送する場合、衝撃を与えないように吊り具やパレットなどが使用されている。例えば、特開平１１−２６３６９６号公報（特許文献１）には、フレーム中央に開口部を有し、この開口部にルツボを載せるパレットが記載されている。しかし、パレットにルツボを載せるには、ルツボを持ち上げる必要があり、特に大型の石英ルツボは安全に持ち上げるのが容易ではない。 When conveying quartz glass crucibles, hanging tools and pallets are used so as not to give an impact. For example, Japanese Patent Application Laid-Open No. 11-263696 (Patent Document 1) describes a pallet having an opening at the center of a frame and mounting a crucible on the opening. However, in order to place the crucible on the pallet, it is necessary to lift the crucible, and particularly a large quartz crucible is not easy to lift safely.
また、紐やベルトを井桁状に組み合わせた吊り具や、たすき掛けに組み合わせた吊り具が知られている。この形状の吊り具は、中央の升目部分あるいは交差部分によってルツボの底部を支えるものであるため、吊り具をルツボに装着する際に、これらの部分をあらかじめルツボ底部の下側に差し込む必要があるが、ルツボ底部の下側に吊り具の中央部を差し込むにはルツボを持ち上げなければならない。また、吊り具を外す時にもルツボを持ち上げる必要があり、作業性に劣る。 In addition, a hanging tool that combines strings and belts in a cross-girder shape and a hanging tool that is combined with a rack are known. Since this type of lifting device supports the bottom of the crucible by a central square or crossing portion, when attaching the lifting device to the crucible, it is necessary to insert these portions below the bottom of the crucible in advance. However, the crucible must be lifted to insert the central part of the hanger under the bottom of the crucible. Moreover, it is necessary to lift the crucible when removing the hanger, resulting in poor workability.
さらに、４本の紐をルツボに掛け渡す吊り具が知られているが、これは紐が外れ易いので作業が面倒であり、四角形の枠を用いるものはルツボ側面の円筒状胴部と形状が合わず、吊り具の枠に弛みができるので、ルツボの固定が不安定になるなどの問題がある。 Furthermore, there is known a hanging tool that hangs four strings to the crucible, but this is troublesome because the string is easy to come off, and the one that uses a square frame is shaped like the cylindrical body on the side of the crucible. Since it does not fit, the frame of the hanger can be loosened, causing problems such as unstable crucible fixation.
従来の上記問題を改善した吊り具が特開２００４−２７７０３２号公報（特許文献２）に開示されている。この吊り具は縦向きのベルトと横向きのベルトが石英ルツボの側面に容易に掛け渡されるように一体に連結されているので、吊り具の着脱作業が容易であり、かつ安定に石英ルツボを支えることができる利点を有している。
本発明は、上記吊り具をさらに改善したものであり、石英ルツボ等の筒状容器全体を包み込みこんで吊り上げることによって、吊り上げ時の安定性をさらに高め、また着脱作業がさらに容易な吊り具を提供する。 The present invention is a further improvement of the above-described hanging tool. By wrapping and lifting the entire cylindrical container such as a quartz crucible, the lifting tool can be further improved in stability during lifting, and the lifting tool can be easily attached and detached. provide.

以下、図面を参照して本発明を具体的に説明する。
本発明の吊り具を図１に示す。図示するように、吊り具１０は、石英ルツボなどの筒状容器２０を包み込む筒状シート１１、該筒状シート底部１２の絞り固定手段１５、該筒状シート１１の上側に延びる吊りベルト１４を有している。
Hereinafter, the present invention will be specifically described with reference to the drawings.
The hanging tool of the present invention is shown in FIG. As shown in the figure, the hanger 10 includes a cylindrical sheet 11 that wraps a cylindrical container 20 such as a quartz crucible, a diaphragm fixing means 15 at the cylindrical sheet bottom 12, and a suspension belt 14 that extends above the cylindrical sheet 11. Have.
図示するように、筒状シート１１はその内部に収納する石英ルツボ等の筒状容器よりも横幅がやや大きいものが用いられる。また、筒状シート１１の高さは吊り上げたときに筒状容器の全体を包み込むことができるように該容器よりも高さの長いものが好ましい。該筒状シート１１の上部および底部は開口しており、この底部開口を通じて石英ルツボ等が出し入れされる。 As shown in the drawing, the cylindrical sheet 11 has a slightly larger width than a cylindrical container such as a quartz crucible housed therein. The cylindrical sheet 11 is preferably longer than the container so that the entire cylindrical container can be wrapped up when it is lifted. The upper part and the bottom part of the cylindrical sheet 11 are opened, and a quartz crucible and the like are taken in and out through the bottom part opening.
また、好ましくは、筒状シート１１の胴部１３には該胴部１３の周囲を巡るリング状の補強材１６が設けられている。このリング状補強材１６によって、該筒状シート１１を吊り下げたときに筒状に膨らんだ状態を保つことができ、該シートの底部開口を広げた状態で石英ルツボ等に被せることによって、石英ルツボ等を容易に内部に出し入れすることができる。 Preferably, a ring-shaped reinforcing material 16 that surrounds the periphery of the body portion 13 is provided on the body portion 13 of the tubular sheet 11. The ring-shaped reinforcing member 16 can keep the tubular sheet 11 in a swelled state when the tubular sheet 11 is suspended. By covering the quartz crucible or the like with the bottom opening of the sheet widened, A crucible or the like can be easily put in and out.
図示する例では、筒状シート底部１２の最下部に該底部１２の周囲を巡る紐１５が脱落しないように通し掛けられており、該紐１５を筒状容器胴部の横幅以下に結び止めすることによって該容器が脱落しないように収納する絞り固定手段が形成されている。該紐１５の取付方法としては、シート底部の開口縁を袋状に形成してその内部に回し通してもよく、または該底部１２の布地の表裏を交互に貫いて紐１５が該底部の最下部を一巡するように通し渡してもよい。 In the example shown in the figure, a string 15 that circulates around the bottom 12 is passed through the bottom of the cylindrical sheet bottom 12 so as not to drop off, and the string 15 is tied to a width equal to or less than the lateral width of the cylindrical container body. Accordingly, a throttle fixing means for storing the container so as not to drop off is formed. The string 15 may be attached by forming the opening edge of the bottom of the sheet in a bag shape and passing it through the inside, or alternately passing through the bottom and back of the fabric of the bottom 12 so that the string 15 is at the bottom of the bottom. You may pass through the lower part.
また、図示する例では、吊りベルトは筒状シート１１の前後および左右に合計４本の吊りベルト１４が設けられている。これらの吊りベルト１４は筒状シート１１の底部から上端部にかけて縦方向に固着されており、さらに該筒状シート１１の上端部から上方に延びて互いに連結されている。ホイスト等の搬送手段のフックをこの吊りベルト１４の連結部分に引っかけて全体を吊り上げる。 In the illustrated example, the suspension belt is provided with a total of four suspension belts 14 on the front and rear and on the left and right of the tubular sheet 11. These suspension belts 14 are fixed in the vertical direction from the bottom to the upper end of the tubular sheet 11, and further extend upward from the upper end of the tubular sheet 11 and are connected to each other. A hook of a conveying means such as a hoist is hooked on the connecting portion of the suspension belt 14 to lift the whole.
この吊りベルト１４は筒状シート１１の縦方向に固着されているので、全体を吊り上げたときに、荷重が上記吊りベルト１４に沿って縦方向に支えられることになり、筒状シート１１の上下の撚れが殆ど無く、安定に吊り下げることができる。なお、吊りベルト１４の本数は４本に限らない。３本でもよく、４本以上でもよい。 Since the suspension belt 14 is fixed in the vertical direction of the cylindrical sheet 11, when the whole is lifted, the load is supported in the vertical direction along the suspension belt 14. There is almost no twist of and can be suspended stably. Note that the number of the suspension belts 14 is not limited to four. Three or four or more may be used.
なお、吊りベルト１４の上端をあらかじめ連結した形状にせず、互いに分離した状態にして各々の上端にリングを設け、吊り上げるときに該リングを寄せ集めてホイスト等のフックに一体に引っかけるようにしてもよい。 The upper ends of the suspension belts 14 are not connected in advance, but are separated from each other, and a ring is provided at each upper end. When the suspension belt is lifted, the rings are gathered together and hooked on a hook such as a hoist. Good.
図示するように、筒状シート１１を搬送手段に吊り下げた状態で石英ルツボ２０の上方に設置する〔図２（Ａ）〕。該筒状シート１１の底部を開いた状態で石英ルツボ２０に向かって筒状シート１１を下降させ、該底部開口から石英ルツボ２０に被せる〔図２（Ｂ）〕。好ましくは、筒状シート底部の紐１５の位置が石英ルツボ底部の湾曲部の下側に達するまで該筒状シート１１を下降させる。次いで、該シート底部開口の大きさが石英ルツボ２０の横幅より狭くなるまで紐１５を絞ってシート底部の最下部を結び止めし、筒状シート内部に石英ルツボ２０を収納する〔図２（Ｃ）〕。この状態で全体を吊り上げ、目的地まで搬送する。 As shown in the drawing, the cylindrical sheet 11 is installed above the quartz crucible 20 while being suspended from the conveying means [FIG. 2 (A)]. With the bottom of the cylindrical sheet 11 open, the cylindrical sheet 11 is lowered toward the quartz crucible 20 and covered over the quartz crucible 20 from the bottom opening [FIG. 2 (B)]. Preferably, the cylindrical sheet 11 is lowered until the position of the string 15 at the bottom of the cylindrical sheet reaches the lower side of the curved portion at the bottom of the quartz crucible. Next, the string 15 is squeezed until the size of the opening at the bottom of the sheet becomes narrower than the lateral width of the quartz crucible 20, and the lowermost part of the bottom of the sheet is fastened. ]]. In this state, the whole is lifted and transported to the destination.
石英ルツボ１０を取り出すときには、筒状シート内部に石英ルツボ２０を収納した状態で吊り下ろし、台座や収納箱などに設置する〔図２（Ｃ）〕。次いで、紐１５の結びを解いてシート底部を開く。さらに、シート底部を開いた状態で筒状シート１１を吊り上げ、筒状シート１１を石英ルツボ２０から上方に引き抜く〔図２（Ｂ）〕。この筒状シート１１はシート底部が開いた状態なので、このまま石英ルツボ２０の収納場所まで移動させ〔図２（Ａ）〕、再び上記収納動作を繰り返すことによって連続的に石英ルツボの吊り下げ移送を行わせることができる。 When the quartz crucible 10 is taken out, the quartz crucible 20 is suspended in a state where the quartz crucible 20 is accommodated in the cylindrical sheet, and is installed in a pedestal or a storage box [FIG. 2 (C)]. Next, the string 15 is untied and the seat bottom is opened. Furthermore, the cylindrical sheet 11 is lifted with the sheet bottom open, and the cylindrical sheet 11 is pulled upward from the quartz crucible 20 [FIG. 2 (B)]. Since the cylindrical sheet 11 is in a state where the bottom of the sheet is open, the quartz crucible 20 is moved to the storage location of the quartz crucible 20 as it is [FIG. Can be done.
本発明の吊り具は、筒状シートを上方から容器に被せてシート底部を絞り固定することによって容易にシート内部に容器を収納でき、また絞り固定を解除することによって簡単に引き抜くことができるので、容器に対する脱着作業が極めて簡単かつ迅速であり、球状容器や筒状容器、底部湾曲容器などについても簡単に吊り下げ移送することができる。 The hanger of the present invention can easily store the container inside the sheet by covering the cylindrical sheet over the container from above and fixing the bottom of the sheet by squeezing, and can be easily pulled out by releasing the squeeze fixing. The detaching operation with respect to the container is very simple and quick, and a spherical container, a cylindrical container, a bottom curved container and the like can be easily suspended and transferred.
さらに本発明の吊り具は、容器をそのまま包み込んで吊り上げるので、球状容器や筒状容器、底部湾曲容器などについても移動中の荷崩れがなく、安定に移送することができる。また、筒状シートを上方から容器に被せて収納し、また上方から引き抜くので、シートを横に広げる必要がなく、作業スペースが狭い場所においても使用することができる。さらに、本発明の吊り具は、筒状シートの開口径より小さい大きさの容器について共通に使用することができる。 Furthermore, since the lifting tool of the present invention wraps and lifts the container as it is, the spherical container, the cylindrical container, the bottom curved container and the like can be stably transferred without being collapsed during movement. Further, since the cylindrical sheet is stored on the container from above and pulled out from above, it is not necessary to spread the sheet horizontally, and it can be used even in a place where the work space is small. Furthermore, the hanger of the present invention can be commonly used for containers having a size smaller than the opening diameter of the cylindrical sheet.
