200914346 九、發明說明 【發明所屬之技術領域】 本發明是關於板狀構件搬運裝置的搬運滾子構件’詳 細地說是關於玻璃板構件等板狀構件搬運時承載板狀構件 朝搬運方向移動板狀構件用的搬運滾子構件。 【先前技術】 玻璃板等板狀構件搬運用的裝置，所採用的構成是由 來自於馬達的動力對配設成平行的複數旋轉軸進行驅動’ 利用該各旋轉軸的旋轉將板狀構件朝期望行進方向搬運。 於該構成的該搬運裝置中，上述各旋轉軸的旋轉是由安裝 在其軸線周圍的複數滾輪傳達至板狀構件，具體而言’是 從各滾輪半徑方向上方將板狀構件載置在滾輪上，透過摩 擦力使與各旋轉軸的旋轉連動形成旋轉之滾輪的旋轉傳達 至板狀構件下面（與滾輪的接觸面）對板狀構件進行搬 運。 上述滾輪設有軸孔（以下亦稱「輪轂孔」），該軸孔 是以穿通搬運裝置的各旋轉軸形成與該旋轉軸連結。因 此，於滾輪的軸孔內壁就會作用有旋轉軸大驅動力造成的 面壓，該面壓對策是以輪轂成型或鍵結合爲代表。具體而 言，前者是爲了降低面壓而加大軸孔的寬幅，即爲了增加 軸孔軸線方向的長度而成型爲輪轂。另外，後者是對軸孔 即圓孔進行切削，於輪轂內壁設置鍵槽'在旋轉軸表面裝 設鍵，將該鍵嵌合於鍵槽企圖達到增加旋轉軸和滾輪的連 -4- 200914346 結強度。 於此若論及滾輪的材質時’習知的搬運輸出機12用 滾輪是使用樹脂製滾輪’其代表已知有使用PEEK製滾輪 或POM製滾輪。然而，使用PEEK製滾輪時，由於是高 硬度但是爲高價的材質’因此在進行輪轂成型時有成本增 加的問題。另外，使用pom製滾輪時，由於是較便宜的 材質因此較少有PEEK製滾輪般成本增加的問題，但因是 軟質性材質所以進行結合時會有連結強度的問題。換句話 說，於習知搬運裝置的各旋轉軸的軸線周圍的滾輪（以下 稱「滾子構件」或「搬運裝置用滾子構件」）構成，是難 以達到能夠擔保與旋轉軸的連結強度和提供價廉物美的滾 子構件。 此外，如上述以習知的鍵結合使滾子構件和旋轉軸連 結的方法，在滾子構件側的鍵槽及旋轉軸側的鍵槽和鍵之 間會產生間隙，因此爲了抑制該間隙產生確保充分連結， 需要另外以螺絲結合滾子構件和旋轉軸，導致加工成本及 勞力增加或甚至產生旋轉軸表面損傷的弊害。再加上，若 有上述螺絲結合時’則在滾子構件彈性疲乏時就算要進行 更換也需每逢更換就需拆卸螺絲，導致勞力需求變大。 [專利文獻1 ]日本特開2 0 0 5 - 2 7 9 3 1 1號公報 【發明內容】 [發明欲解決之課題] 本發明是爲解決上述問題點而爲的發明，其目的是， -5- 200914346 針對玻璃板構件等板狀構件搬運用的裝置，提供一種可確 保滾子構件和旋轉軸的充分連結狀態，同時能夠達到降低 旋轉軸損傷、降低加工成本及勞力之可使板狀構件朝搬運 方向移動的搬運裝置用滾子構件。 [用以解決課題之手段] 本發明是針對由排列朝同方向旋轉驅動的複數多角形 狀旋轉軸搬運目的對象物的裝置，提供一種裝設在各旋轉 軸周線周圍可承載上述目的對象物的搬運裝置用滾子構 件。該滾子構件’具備：於軸線方向從一方端部至另一方 端部具有中空輪轂孔的筒狀輪轂構件；及在輪轂構件的軸 線方向大致中間位置於該輪轂構件外壁面周圍固定成環狀 的環狀構件。此外，輪轂構件的輪轂孔能以可滑動狀態嵌 合於各旋轉軸，例如最好是形成爲大致六角形狀。因此， 旋轉軸也需要形成可和輪轂孔嵌合的六角形狀等多角形 狀。 另外，輪轂構件和環狀構件是以熱塑性樹脂材料一體 成型’例如：熱塑性樹脂材料最好是以聚醯胺、聚縮醛 (POM)、聚碳酸酯、聚氧化二甲基苯、聚對苯二甲酸二 丁酯、超高分子量聚乙烯、聚偏二氟乙烯當中的任一材質 構成。再加上，輪轂構件和環狀構件，也可混合有除靜電 材料’例如：除靜電材料是使用碳。 . 此外’環狀構件的外周緣是以橡皮環包覆著，橡皮環 最好是以乙丙橡膠或矽橡膠構成。再加上，該橡皮環也可 -6- 200914346 添加有碳等除靜電材料。 另外，本發明的搬運裝置，具備有：形成排列朝同方 向旋轉驅動的複數多角形狀旋轉軸；裝設在各旋轉軸的軸 線周圍可和該各旋轉軸合作形成旋轉的滾子構件；及在各 旋轉軸分別裝設的滾子構件之間於內部穿通有上述旋轉軸 形成配設的中空棒構件。該滾子構件，具有：於軸線方向 從一方端部至另一方端部具有中空輪轂孔的筒狀輪轂構 件；及在輪轂構件的軸線方向大致中間位置於該輪轂構件 外壁面周圍固定成環狀的環狀構件，再加上，輪轂構件的 輪轂孔能以可滑動狀態嵌合於各旋轉軸，棒構件是可將分 別安裝在各旋轉軸的滾子構件定位在旋轉軸的軸線方向。 另’針封各個構成的構件其最佳材質或附加材料是和上述 搬運裝置用滾子構件相同。其他，由於能夠使用軟質材料 所以即將其與旋轉軸的嵌合精度稍微降低但材質本身具延 展性，因此能夠吸收製造誤差。其結果，能夠獲得成品率 佳的搬運裝置用滾子構件。 [發明效果] 根據本發明的搬運裝置用滾子構件及搬運裝置時，由 於是具有大致正六角形狀等多角剖面形狀的輪轂孔，因此 即使不進行鍵結合或另外的螺絲結合’但透過多角剖面形 狀與各旋轉軸的嵌合還是能夠同樣地使兩者於旋轉方向充 分連結。即，滾子構件和旋轉軸’由於是固定在旋轉方 向，即使於旋轉時作用有較大的負荷但因滑移或磨耗少因 200914346 此能夠維持確實的連結。 此外，滾子構件是以朝軸方向可滑動的狀態 轉軸，因於各旋轉軸中所配設的各個滾子構件之 棒狀構件，所以藉此不僅可使旋轉軸和滾子構件 轉軸的軸方向，還能夠將棒狀構件從旋轉軸抽出 出滾子構件就能夠容易更換彈性疲乏的滾子構件 另外’滾子構件，因是以多角剖面形狀和旋 形成連結，所以輪轂構件和環狀構件的材質能夠 軟質廣爲所用的工程塑料（樹脂材料）構成，可 如習知的PEEK材等耐熱高功能塑料（耐熱高 脂）。這表示不僅能夠減輕加工勞力、成本，還 降低材料成本。此外，上述軟化材料，也會有耐 的顧慮，但於該狀況時只要另外比橡皮環包覆在 的周圍（外周緣）就足以克服，例如只要使用 EPT等高耐熱性、高強度材質的橡皮環即可。另 運對象物而定，例如搬運玻璃構件時，滾子構件 象物的摩擦有時會產生靜電。於該狀況時習知的 等需要另外設置除靜電手段（電離器等），或者 碳等除靜電材料使滾子構件本身具有除靜功能電 此’本發明的滾子構件是能夠容易混合有除靜電 外’也可於本發明的滾子構件混合有除靜電材料 繞含有泛用除靜電材料的包覆橡膠藉此增大除靜 因此’本發明能夠以低成本提供一種除靜電功能 裝置、搬運裝置用滾子構件。再加上，滾子構件 連結於旋 間插設有 固定在旋 後只要抽 〇 轉軸嵌合 以上述的 以不使用 功能塑樹 能夠大幅 熱性問題 環狀構件 矽橡膠或 外，視搬 和搬運對 PEEK 材 難以混合 ，相對於 材料。此 後，再捲 電功能。 高的搬運 若是使用 -8- 200914346 如上述的軟質塑膠材料時也可利用射出成型，能夠避免如 PEEK材般硬質塑膠只能切削成型所造成製造成本增加的 問題。 【實施方式】 [發明之最佳實施形態] 以下，針對本發明搬運滾子構件的實施形態，以搬運 裝置例示的同時進行說明。首先，以本發明搬運滾子構件 的說明爲前提，說明安裝有該搬運滾子構件的搬運裝置。 第1圖是搬運裝置10從上方看時的平面圖，第2圖 是第1圖搬運裝置10從側方（紙面下方）看時的正面 圖。該搬運裝置10是以玻璃板爲搬運對象朝箭頭符號X 方向進行搬運。首先，搬運裝置10排列配設有可軸旋轉 的複數旋轉軸16，其軸線方向長度至少比玻璃板的寬度還 長。接著，於搬運裝置10的側方，安裝有馬達14，由來 自於馬達14的動力使複數的旋轉軸16形成軸旋轉。該搬 運裝置1 〇是形成爲利用該各旋轉軸1 6的旋轉使玻璃板 (板狀構件）朝期望行進方向搬運的構成。 上述搬運裝置10中’是由安裝在上述各旋轉軸16軸 線周圍的複數滾子構件1 2將各旋轉軸1 6的旋轉傳達至板 狀構件。第1圖例示的搬運裝置1 0是針對各旋轉軸1 6從 紙面左分安裝有4、5、4、5、4、5、4、5、4個滾子構 件1 2 ’但安裝在個旋轉軸1 6的滾子構件1 2的數量是根據 玻璃板或搬運裝置的尺寸等加以適當決定的設計事項。於 -9- 200914346 該滾子構件1 2是從滾輪的半徑方向上方將玻璃板下面 (和滾子構件12的接觸面）載置在滾子構件上，藉由與 各旋轉軸16的旋轉連動形成旋轉的滾子構件12的旋轉透 過摩擦力傳達至板狀構件下面搬運板狀構件。 其次，針對滾子構件1 2的細部進行說明。本實施形 態的說明中，滾子構件12是以第3圖、第4圖所示的2 個滾子構件的剖面圖爲例子進行說明。首先，於第3圖， (a)圖是表不滾子構件12的側面圖，（b)圖是表不 (a )圖滾子構件1 2的輪轂孔20a。該滾子構件1 2是以 POM (聚縮醛）爲主成份構成的樹脂製品。此外，滾子構 件12是大區分爲2個構件構成，即，是由：軸線方向設 有輪轂孔20a的中空輪轂構件20 ;及設置在輪轂構件20 外圍的環狀構件22所構成。該2個構件若考慮其連結強 度是以一體形成爲佳，由於是Ρ Ο Μ製所以不限於切削， 還能夠以便宜價格的射出成型。另，於第3圖的輪轂構件 12是以ΡΟΜ製品爲例進行了說明，但滾子構件12的材 質’也可以是其他的熱塑性樹脂材料例如：聚醯胺、聚碳 酸酯、聚氧化二甲基苯、聚對苯二甲酸二丁酯、超高分子 量聚乙烯、聚偏二氟乙烯等。 接著’針對滾子構件12的輪轂孔20a進行說明。從 第3 ( b )圖也可明顯得知輪轂孔2 0 a的剖面形狀爲六角形 狀。習知的滾子構件其旋轉軸爲圓柱形狀，所以爲該形狀 是基於規格上的認知以鍵結合等爲前提。本發明是排除上 述前提認知’其結果，創作出旋轉軸1 6和滾子構件1 2的 -10- 200914346 兩者剖面形狀，以剖面形狀的吻合形成嵌合結合。該形狀 是可相對於旋轉軸1 6的旋轉使旋轉軸1 6的外表面和滾子 構件1 2的輪轂孔2 0 a的內壁不滑移地形成固定狀態（相 對於旋轉方向）。因此，旋轉軸16及滾子構件12的成型 容易度或固定性良好的剖面形狀是圖示爲六角形狀的輪轂 孔2 0，但只要可使旋轉軸1 6的剖面形狀和滾子構件1 2的 輪轂孔20a的剖面形狀嵌合一致的多角形狀並不特別限定 於六角形狀。例如：即使是5〜1 2角形狀還是能夠發揮相 同效果，特此說明。此外，即使是其他的多角剖面形狀還 是能夠理解這是與滾子構件12的材質強度或輪轂構件20 的軸線長等互相結合之該當業者的設計事項。 另外’如以上所述，滾子構件1 2的環狀構件2 2是於 其外周緣22a承載著玻璃板等搬運對象物。此時搬運對象 物會因本身重量產生彎曲變形，在外周緣22a形成點接 觸。參照第4圖時，如（a)圖所示若將外周緣22a維持 成接近直角的形狀則與搬運對象物24會形成2點接觸 (若也考慮到紙面垂直方向時則成2邊接觸）。於該狀態 下搬運對象物24的本身重量會集中在2點22b，產生損壞 危險性。因此，於本實施形態的滾子構件12，如第4 (b )圖所示是去除外周緣的角，使其能夠以面接觸搬運 對象物2 4。 另一方面，若加大滾子構件12與搬運對象物24的接 觸面時於搬運中產生的靜電也會變大。爲了避免靜電產 生’本滾子構件1 2是以混合有碳等除靜電材料爲佳。該 -11 - 200914346 碳混合是於射出成型時加以混合即可。就只能切削成型的 PEEK材而言，由於是事先從peek製的構件切出成型因 此難以混合碳，但關於此點，本滾子構件由於是使用軟質 並且可射出成型的材料，因此改變碳混合量就能夠自由改 變除靜電功能。 其次’參照第5圖說明本滾子構件的變形例。於該圖 中’其箭頭符號Y方向看的圖是圖示在第6圖。另，對於 標有和第3圖相同參照圖號的構件是表示同一構件。從第 5圖、第6圖也可明確得知，該滾子構件1 12是於第3圖 的滾子構件1 2附加有環狀的構件2 6 (斜線表示）。該構 件2 6是以橡膠形成的構件（稱「橡皮環」），沿著環狀 構件22的外周緣22a包覆在其全周。如以上所述，相較 於PEEK等耐熱高功能塑料（耐熱高功能塑樹脂），P0M 等廣爲所用的工程塑料（泛用工程塑膠）爲質軟，具有耐 熱性低的特質。因此，容易於搬運對象物2 4的搬運中磨 損，特別是當搬運對象物24變高溫時磨損傾向就變強。 第5圖、第6圖滾子構件112的橡皮環26是爲了避免該 磨損而設置。 該橡皮環26是以乙丙橡膠（EPT橡膠）或矽橡膠爲 主成份構成爲佳。其理由是，其他的橡膠材料，相較於一 般泛用橡膠其耐熱性占優勢，此點能夠避免對環狀構件22 傳導熱。此外，即使是一般泛用橡膠等普遍的橡膠材料還 是能夠避免由滾子構件1 2直接承載搬運對象物2 4，因此 其優點爲橡皮環26磨損只要更換橡皮環即可，不需滾子 -12- 200914346 構件12 件2 2的 維護就變 又加 混合有碳 說明的內 型，但僅 能不夠的 除靜電材 射出成型 於此 12(112： 列的滾輪 滾子構件 有除靜電 是不混合 知對於滾 配設在搬: 夠，其是 件1 2全體 再加_ 著參照圖丨 中空棒狀 12及搬運 整體更換’再加上只要將橡皮環26包覆在環狀構 外周緣2 2 a就能夠形成裝設因此對於彈性疲乏的 容易並且低成本化。 上’於第5圖的滾子構件112的橡皮環26也以 等除靜電材料爲佳。如第3圖的滾子構件1 2所 容滾子構件其本身也可混合有除靜電材料加以成 有滾子構件本身的除靜電功能還是會有除靜電功 狀況’或者滾子構件是以切削成型就難以混合有 料。於該上述狀況時，同樣地因橡皮環26是以 製成，所以能夠容易混合有除靜電物質。 再度回到第1圖進行說明。針對搬運裝置用滾子 以下參照圖號1 12省略）從左算起第4列、第7 是和其他滾輪不同，以斜線表示。以斜線表示的 1 2是於上述的滾子構件1 2及/或橡皮環26混合 材料的滾子構件’沒有斜線標示的滾子構件1 2 有除靜電材料的滾子構件丨2。從該圖也可明確得 子構件1 2是否要混合有除靜電材料並不是針對 運裝置10的滾子構件12全部，只要—部份就足 該當業者根據搬運對象物的除靜電功能和滾子構 丨的成本做爲決定的設計事項。 上，第1圖中在旋轉軸丨6的參照圖號下方標示 號26。這是表示狀態爲內部穿通有旋轉軸1 6的 構件2 8。如以上所述，本搬運裝置用滾子構件 裝置是將旋轉軸16和輪轂孔20a爲同—多角 -13- 200914346 剖面形狀藉此提供可使兩者旋轉方向連結確實的構成°然 而，本滾子構件1 2基於其更換容易度而形成爲能夠滑動 於軸線方向。於是’本發明是在進行軸線方向的連結的同 時，將上述中空棒狀構件28穿通於旋轉軸16藉此執行對 旋轉軸1 6之滾子構件1 2的定位。 詳細地說，是在各旋轉軸所配設的滾子構件12各個 之間穿插有與該間隔同一長度的棒狀構件2 8。例如：以第 1圖最左列的旋轉軸1 6爲例示時，滾子構件1 2是於軸線 方向配設有4個，在滾子構件1 2之間（及端部）穿插有5 支棒狀構件。採用上述構成的搬運裝置1 0時，不僅能夠 容易固定滾子構件1 2，更換時只要從旋轉軸1 6依順序重 覆抽出棒狀構件28、滾子構件1 2，再放入就能夠完成更 換作業，能夠達到維修作業的效率性。 再加上，採用棒狀構件2 8形成的滾子構件1 2固定方 法時，只要改變棒狀構件28的長度就能夠移動滾子構件 1 2的位置，因應搬運對象物或滾子構件1 2全數量時的滾 子構件1 2的定位調整就變容易。另，棒狀構件28和滾子 構件12的固定，明顯得知是以前者的端部和後者的環狀 構件22的接觸形成固定。棒狀構件2 8，若考慮到除靜電 功能、耐熱性、加工容易度等時是以樹脂製爲佳，但也可 考慮採用金屬材料等。 以上’針對本發明的實施形態進行了說明，但於此所 揭示的內容僅例示內容，該當業者應能夠容易理解在不脫 離申請專利範圍精神、說明書揭示內容的範圍還有其他實 -14 -

A conveying roller member for a member. [Prior Art] A device for transporting a plate-shaped member such as a glass plate is configured such that a power from a motor is driven to a plurality of parallel rotating shafts arranged in parallel. The rotation of each of the rotating shafts causes the plate-shaped member to face It is desirable to carry in the direction of travel. In the transport device of the above configuration, the rotation of each of the rotating shafts is transmitted to the plate-like member by a plurality of rollers attached around the axis thereof, and specifically, the plate-shaped member is placed on the roller from the radial direction of each roller. Then, the rotation of the roller that rotates in conjunction with the rotation of each of the rotating shafts is transmitted to the lower surface of the plate-like member (the contact surface with the roller) by the frictional force to convey the plate-shaped member. The roller is provided with a shaft hole (hereinafter also referred to as "hub hole"), and the shaft hole is formed to be coupled to the rotating shaft by each of the rotating shafts of the feedthrough. Therefore, the inner wall of the shaft hole of the roller acts on the surface pressure caused by the large driving force of the rotating shaft, and the surface pressure countermeasure is represented by the hub forming or the key combination. Specifically, the former is to increase the width of the shaft hole in order to reduce the surface pressure, that is, to form the hub in order to increase the length in the axial direction of the shaft hole. In addition, the latter cuts the shaft hole, that is, the round hole, and provides a key groove on the inner wall of the hub. The key is mounted on the surface of the rotating shaft, and the key is fitted into the key groove in an attempt to increase the connection of the rotating shaft and the roller. . When the material of the roller is used here, the conventional roller for the conveyance output machine 12 is a resin roller, which is known to use a roller made of PEEK or a roller made of POM. However, when a roller made of PEEK is used, it is a material having a high hardness but a high price. Therefore, there is a problem that the cost is increased when the hub is formed. Further, when a pom-made roller is used, since it is a relatively inexpensive material, there is a problem that the cost is increased as compared with a PEEK-made roller. However, since it is a soft material, there is a problem in connection strength when bonding. In other words, it is difficult to achieve the connection strength between the axis around the axis of each of the rotating shafts of the conventional conveying device (hereinafter referred to as "roller member" or "roller member for conveying device"), and it is difficult to secure the connection strength with the rotating shaft. Provides inexpensive roller components. Further, as described above, the method of connecting the roller member and the rotating shaft by a conventional key combination causes a gap between the key groove on the roller member side and the key groove on the rotating shaft side and the key, so that sufficient clearance is ensured in order to suppress the gap. The connection requires additional screwing of the roller member and the rotating shaft, resulting in an increase in processing cost and labor or even a damage to the surface of the rotating shaft. In addition, if the above-mentioned screws are combined, it is necessary to remove the screws every time the replacement of the roller members is required, so that the labor demand becomes large. [Patent Document 1] Japanese Patent Laid-Open Publication No. H0 5 - 2 7 9 3 1 1 SUMMARY OF THE INVENTION [Problem to be Solved by the Invention] The present invention has been made to solve the above problems, and an object thereof is to provide - 5-200914346 A device for transporting a plate-shaped member such as a glass plate member is provided, and a plate-like member capable of ensuring a sufficient connection state between the roller member and the rotating shaft and reducing the damage of the rotating shaft and reducing the processing cost and labor can be provided. A roller member for a conveying device that moves in the conveying direction. [Means for Solving the Problem] The present invention provides an apparatus for transporting an object of interest by a plurality of polygonal rotating shafts that are rotationally driven in the same direction, and is provided to be mounted around the circumference of each rotating shaft to carry the object of interest. Roller member for conveying device. The roller member ′ includes a cylindrical hub member having a hollow hub hole from one end portion to the other end portion in the axial direction, and a ring shape is fixed around the outer wall surface of the hub member at a substantially intermediate position in the axial direction of the hub member. Ring member. Further, the hub hole of the hub member can be fitted to each of the rotating shafts in a slidable state, and is preferably formed into a substantially hexagonal shape, for example. Therefore, the rotating shaft also needs to have a polygonal shape such as a hexagonal shape that can be fitted into the hub hole. Further, the hub member and the annular member are integrally molded of a thermoplastic resin material. For example, the thermoplastic resin material is preferably polyamine, polyacetal (POM), polycarbonate, polyoxymethylenebenzene, polyparaphenylene. It is composed of any of dibutyl dicarboxylate, ultrahigh molecular weight polyethylene, and polyvinylidene fluoride. Further, the hub member and the annular member may be mixed with a static eliminating material. For example, the static eliminating material is carbon. Further, the outer periphery of the annular member is covered with a rubber ring, and the rubber ring is preferably made of ethylene propylene rubber or ruthenium rubber. In addition, the rubber ring can also be added to the static cleaning material such as carbon. Further, the conveying apparatus according to the present invention includes: a plurality of polygonal rotating shafts that are arranged to be rotationally driven in the same direction; and roller members that are rotatable around the axes of the respective rotating shafts to form rotations; and A hollow rod member formed by the above-described rotating shaft is interposed between the roller members respectively provided in the respective rotating shafts. The roller member has a cylindrical hub member having a hollow hub hole from one end portion to the other end portion in the axial direction, and is fixed in a ring shape around the outer wall surface of the hub member at a substantially intermediate position in the axial direction of the hub member. Further, the annular member of the hub member can be slidably fitted to each of the rotating shafts, and the rod member can position the roller members respectively attached to the respective rotating shafts in the axial direction of the rotating shaft. Further, the optimum material or additional material of each member of the needle seal is the same as that of the above-described roller member for a conveyance device. In addition, since a soft material can be used, the fitting precision with the rotating shaft is slightly lowered, but the material itself is malleable, so that manufacturing errors can be absorbed. As a result, a roller member for a conveying device having a good yield can be obtained. [Effect of the Invention] According to the roller member and the conveying device for a conveying device of the present invention, since the hub hole has a polygonal cross-sectional shape such as a substantially hexagonal shape, the multi-angle cross section is transmitted without the key joining or the other screwing. The fitting of the shape and each of the rotating shafts can also sufficiently connect the two in the same direction of rotation. In other words, since the roller member and the rotating shaft ' are fixed in the rotating direction, even if a large load acts during the rotation, the slip or the wear is small, and the positive connection can be maintained by 200914346. Further, the roller member is a state in which the roller member is slidable in the axial direction, and the rod member of each of the roller members disposed in each of the rotary shafts can thereby not only rotate the shaft of the rotating shaft and the roller member In the direction, the rod member can be easily extracted from the rotating shaft and the roller member can be easily replaced. The elastic roller member can be easily replaced. The roller member is formed by a polygonal cross-sectional shape and a rotary joint, so that the hub member and the annular member are connected. The material can be made of a wide range of engineering plastics (resin materials) that can be used in a soft manner, such as a heat-resistant high-performance plastic (heat-resistant and high-fat) such as a conventional PEEK material. This means not only reducing labor, cost, but also material costs. In addition, the above-mentioned softening material may also have a resistance problem, but in this case, it is sufficient to overcome the periphery (outer circumference) of the rubber ring, for example, a rubber having high heat resistance and high strength such as EPT is used. Ring can be. Further, depending on the object to be transported, for example, when the glass member is conveyed, static electricity may be generated by friction of the roller member. In this case, it is necessary to additionally provide a static elimination means (ionizer, etc.), or a static elimination material such as carbon so that the roller member itself has a static elimination function. The roller member of the present invention can be easily mixed. In addition, the roller member of the present invention can be mixed with a static eliminating material around the covering rubber containing the general-purpose static eliminating material to thereby increase the static elimination. Therefore, the present invention can provide a static eliminating function device and handling at a low cost. The roller member for the device. In addition, the roller member is coupled to the inter-rotation and is fixed to the rear of the screw, as long as the twirling shaft is fitted in the above-mentioned manner, so that the plastic member can be used without a function, and the annular member can be greatly heated. PEEK materials are difficult to mix, relative to materials. After that, re-roll the function. High handling If you use -8- 200914346 soft plastic materials as described above, you can also use injection molding to avoid the problem of increased manufacturing costs due to the fact that rigid plastics such as PEEK can only be cut and formed. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a conveying roller member according to the present invention will be described with reference to a conveying device. First, the conveyance device to which the conveyance roller member is attached will be described on the premise of the description of the conveyance roller member of the present invention. Fig. 1 is a plan view of the conveying device 10 as seen from above, and Fig. 2 is a front view of the conveying device 10 as viewed from the side (below the paper surface). The conveying device 10 conveys the glass plate as a conveyance target in the direction of the arrow X. First, the conveying device 10 is arranged with a plurality of shafts 16 that are pivotable, and the length in the axial direction is at least longer than the width of the glass sheet. Next, a motor 14 is attached to the side of the conveying device 10, and a plurality of rotating shafts 16 are pivoted by the power from the motor 14. The transporting device 1 is configured to convey the glass plate (plate member) in a desired traveling direction by the rotation of each of the rotating shafts 16. In the above-described conveying device 10, the rotation of each of the rotating shafts 16 is transmitted to the plate-like member by a plurality of roller members 1 2 attached around the axis of each of the rotating shafts 16. In the conveying device 10 illustrated in Fig. 1, four, five, four, five, four, five, four, five, and four roller members 1 2 ' are attached to the left side of the paper for each of the rotating shafts 16. The number of the roller members 1 2 of the rotating shaft 16 is appropriately determined depending on the size of the glass plate or the conveying device. -9-200914346 The roller member 12 is placed on the roller member from the upper side of the roller in the radial direction of the roller (and the contact surface of the roller member 12), and is interlocked with the rotation of each of the rotary shafts 16 The rotation of the roller member 12 that forms the rotation is transmitted to the plate-like member under the plate-like member by the frictional force. Next, the details of the roller member 12 will be described. In the description of the present embodiment, the roller member 12 will be described by taking a cross-sectional view of two roller members shown in Figs. 3 and 4 as an example. First, in Fig. 3, (a) is a side view showing the roller member 12, and (b) is a view showing the hub hole 20a of the roller member 12 in the figure (a). The roller member 12 is a resin product mainly composed of POM (polyacetal). Further, the roller member 12 is mainly composed of two members, that is, a hollow hub member 20 provided with a hub hole 20a in the axial direction, and an annular member 22 provided at the outer periphery of the hub member 20. It is preferable that the two members are integrally formed in consideration of the connection strength, and since they are made of Ρ Μ, they are not limited to cutting, and can be injection-molded at a low price. Further, the hub member 12 in Fig. 3 has been described as an example of a tantalum product, but the material of the roller member 12 may be other thermoplastic resin materials such as polyamine, polycarbonate, or polyoxymethylene. Base benzene, polybutylene terephthalate, ultra high molecular weight polyethylene, polyvinylidene fluoride, and the like. Next, the hub hole 20a of the roller member 12 will be described. It is also apparent from the third (b) diagram that the cross-sectional shape of the hub hole 20 a is hexagonal. Conventional roller members have a cylindrical shape, and therefore the shape is based on the assumption that the specification is based on key bonding or the like. The present invention excludes the above-mentioned premise, and as a result, creates a cross-sectional shape of both the rotating shaft 16 and the roller member 12 - -10-200914346, and forms a fitting joint by the anastomosis of the cross-sectional shape. This shape is such that the outer surface of the rotating shaft 16 and the inner wall of the hub hole 20 a of the roller member 12 are fixed in a fixed state (relative to the direction of rotation) with respect to the rotation of the rotating shaft 16 . Therefore, the cross-sectional shape in which the rotational axis 16 and the roller member 12 are easy to mold or have good fixation is a hub hole 20 which is illustrated as a hexagonal shape, but the cross-sectional shape of the rotating shaft 16 and the roller member 1 2 can be made. The polygonal shape in which the cross-sectional shape of the hub hole 20a is fitted is not particularly limited to a hexagonal shape. For example, even if the 5 to 12 corner shape can exert the same effect, it is hereby explained. Further, even if it is another polygonal sectional shape, it can be understood that this is a design matter of the manufacturer in combination with the material strength of the roller member 12 or the axial length of the hub member 20. Further, as described above, the annular member 22 of the roller member 1 2 carries a conveyance object such as a glass plate on the outer peripheral edge 22a. At this time, the object to be conveyed is bent and deformed by its own weight, and a point contact is formed on the outer peripheral edge 22a. When the outer peripheral edge 22a is maintained at a shape close to a right angle as shown in Fig. 4, a two-point contact is formed with the object 24 to be transported (if two sides are also taken into consideration in consideration of the vertical direction of the paper) . In this state, the weight of the object to be transported 24 is concentrated at 2:22b, which is dangerous to damage. Therefore, in the roller member 12 of the present embodiment, as shown in Fig. 4(b), the corner of the outer peripheral edge is removed, so that the object 24 can be conveyed by surface contact. On the other hand, when the contact surface between the roller member 12 and the object 24 to be conveyed is increased, the static electricity generated during transportation increases. In order to avoid static electricity generation, the present roller member 12 is preferably a static eliminating material such as carbon. The -11 - 200914346 carbon blend can be mixed during injection molding. In the case of a PEEK material which can only be cut and formed, it is difficult to mix carbon because it is cut out from a member made of peek in advance, but in this regard, since the roller member is made of a soft material and can be injection molded, the carbon is changed. The mixing amount is free to change the static elimination function. Next, a modification of the roller member will be described with reference to Fig. 5. In the figure, the figure seen in the direction of the arrow Y is shown in Fig. 6. In addition, members denoted by the same reference numerals as in Fig. 3 denote the same members. As is clear from Figs. 5 and 6, the roller member 12 is attached to the roller member 1 2 of Fig. 3 with a ring-shaped member 26 (indicated by oblique lines). The member 26 is a member formed of rubber (referred to as a "rubber ring") and is wrapped around the entire circumference of the annular member 22 around its outer periphery 22a. As described above, compared with heat-resistant high-performance plastics such as PEEK (heat-resistant high-performance plastic resin), P0M and other widely used engineering plastics (general engineering plastics) are soft and have low heat resistance. Therefore, it is easy to wear during transportation of the object to be transported 24, and particularly when the object to be transported 24 is heated to a high temperature, the tendency to wear becomes strong. The rubber ring 26 of the roller member 112 of Figs. 5 and 6 is provided to avoid such wear. The rubber ring 26 is preferably composed of ethylene propylene rubber (EPT rubber) or ruthenium rubber as a main component. The reason is that other rubber materials are superior in heat resistance to the general-purpose rubber, and this can avoid conduction of heat to the annular member 22. Further, even a general rubber material such as a general-purpose rubber can prevent the roller member 12 from directly carrying the object to be transported, and therefore has the advantage that the rubber ring 26 is worn as long as the rubber ring is replaced, and no roller is required. 12- 200914346 The maintenance of 12 parts 2 2 of the component is changed and the internal type of carbon is mixed. However, only the static electricity removal material can be injection molded on this 12 (112: the roller roller components of the column are not mixed with static electricity. It is known that the roll is arranged to move: enough, it is a piece of 1 2 plus _ with reference to the figure 丨 hollow rod 12 and the overall replacement of the transfer' plus the rubber ring 26 is wrapped around the outer periphery of the ring structure 2 2 a It is possible to form the mounting and thus it is easy and cost-effective to fatigue. The rubber ring 26 of the roller member 112 of the above Fig. 5 is also preferably an isostatic material. The roller member 1 of Fig. 3 The capacity roller member itself may be mixed with a static eliminating material to form a roller member itself, or may have a static eliminating function. Or the roller member is difficult to mix with the cutting material. Time Similarly, since the rubber ring 26 is formed, it is possible to easily mix and remove the static electricity removing material. The description will be made again back to Fig. 1. The roller for the conveying device is omitted below with reference to Fig. 1 12) and the fourth column is counted from the left. The 7th is different from other scroll wheels and is indicated by a slash. 1 2 is a roller member of the above-described roller member 12 and/or rubber ring 26 mixed material. The roller member 1 having no oblique line indicates a roller member 2 having a static eliminating material. It can also be seen from the figure whether or not the sub-assembly 1 2 is to be mixed with the static-removing material and is not the entire roller member 12 for the transport device 10, as long as the part is sufficient for the operator to remove the static electricity function and the roller according to the object to be transported. The cost of constructing is the design matter of the decision. In the first figure, the number 26 is indicated below the reference figure of the rotary shaft 丨6. This is a member 28 indicating that the state is internally passed through the rotating shaft 16. As described above, the roller member device of the present invention has a cross-sectional shape in which the rotating shaft 16 and the hub hole 20a have the same-polygon-13-200914346 cross-sectional shape, thereby providing a structure in which the two rotating directions can be reliably connected. The sub-member 1 2 is formed to be slidable in the axial direction based on the ease of replacement. Thus, the present invention performs the positioning of the roller member 12 for the rotating shaft 16 by piercing the hollow rod-shaped member 28 to the rotating shaft 16 while performing the axial direction coupling. Specifically, a rod-shaped member 28 having the same length as the interval is interposed between the roller members 12 disposed on the respective rotating shafts. For example, when the rotation axis 16 of the leftmost column of Fig. 1 is taken as an example, the roller member 12 is disposed in four in the axial direction, and five rollers are interposed between the roller members 12 (and the end portion). Rod member. When the conveying device 10 having the above configuration is used, not only the roller member 12 can be easily fixed, but also the rod member 28 and the roller member 12 can be repeatedly extracted from the rotating shaft 16 in order, and then placed in the vehicle. Replacement work can achieve the efficiency of maintenance work. Further, when the roller member 12 is formed by the rod member 28, the position of the roller member 12 can be moved by changing the length of the rod member 28, and the object or the roller member can be transported. The positioning adjustment of the roller member 12 in the full amount becomes easy. Further, the fixing of the rod-shaped member 28 and the roller member 12 is clearly known to be that the contact between the former end portion and the latter annular member 22 is fixed. The rod-shaped member 2 8 is preferably made of a resin in consideration of a static eliminating function, heat resistance, ease of processing, etc., but a metal material or the like can also be considered.
