1276599 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於作爲搭載乘客而將其 」來利用之皮帶式乘客輸送機，特別是 【先前技術】 作爲電動步道加以利用之皮帶式乘 無端環狀皮帶。無端環狀皮帶係藉由設 降口之間的複數個導引滾筒所支承，而 環。以往的乘客輸送機，係具有以配置 滑輪來驅動皮帶之結構。驅，動部多數係 降口附近。 乘客輸送機係具有：作爲搭乘中的 抓持而準備的手扶帶。手扶帶爲無端環 扶帶係以由搭乘口至下降口爲止’沿著 下降口至搭乘口爲止，通過輸送機裝置 行循環。手扶帶，係藉由設置於輸送機 動機構，與皮帶相同的速度驅動。一般 係將手扶帶夾持於驅動滾筒與加壓滾筒 來將手扶帶夾持驅動者爲眾所皆知。 近年，爲了提高乘客的輸送效率’ 乘口附近及下降口附近之皮帶速度爲以 間部之皮帶速度快的中間加速型皮帶式 例如，日本特許3 3 0 8 2 9 8號公報所 移送之「電動步道 關於其驅動機構。 客輸送機，係具備 置於由搭乘口至下 藉由驅動部加以循 於皮帶的祈返部之 設置於搭乘口或下 支承，爲了使乘客 ，捲掛於欄杆。手 欄杆上移動，而由 內返回的方式，進 裝置內的手扶帶驅 ，手扶帶驅動機構 之間，藉由摩擦力 而亦可見，對於搭 往程度者，而在中 乘客輸送機。 記載之「輸送裝置 (2) (2)1276599 」’其具有移動速度慢之低速移送部、與移動速度快之高 速移送部。此輸送裝置係藉由將乘客從低速移送部轉乘至 高速移送部、或從高速移送部轉乘至低送移送部，來達到 中間加速型。 又日本特開平7-23 28 85號公報所記載之「電動步道」 ’其將移送速度不同之複數個皮帶直列地配置。可伸縮之 多數個伸縮托板捲掛於這些皮帶全體。伸縮托板係受到皮 帶驅動而循環移動。此「電動步道」係藉由因應各皮帶的 速度使伸縮托板伸縮，來達到中間加速型。 【發明內容】 但，乘客輸送機係當運送距離變長時，作用於皮帶的 負擔變大。因此，會有僅藉由配置於皮帶折返部之驅動部 無法傳達充分的驅動力之情況產生。例如，皮帶搖擺地朝 前後脈動。如此的問題不僅存於皮帶式電動步道，亦爲移 動距離長的皮帶式輸送裝置全體之共通問題。 如上述般，即使在皮帶長的情況，也能以驅動滾筒與 加壓滾筒夾持皮帶，產生摩擦力來驅動皮帶，但皮帶會因 運轉條件而承受過大的張力或面壓力。因此，會有皮帶壽 命降低之虞。 且，在被分類成中間加速型之乘客輸送機中，如曰本 特許第3 3 0 8 2 9 8號公報所記載之「輸送裝置」般，在移動 速度不同的移送部之間所產生的轉移部之速度變化爲不^ 續。故，在轉移部，也會有乘客搖晃或跌倒之情事，對於 -6- (3) (3)1276599 乘客安全上並不理想。 又，在日本特開平7-23 2 8 8 5號公報所記載之「電動步 道」，當伸縮托板延伸時，會有伸縮托板無法物理性地縮 短的缺失之可能性產生。 因此，針對運送距離長的皮帶式乘客輸送機，被要求 可使對於皮帶部分的負擔少、可正確且圓滑地驅動；及確 保在運轉中對於乘客之安全性兩立之中間加速型皮帶式乘 客輸送機。 [用以解決課題之手段] 本發明之皮帶式乘客輸送機，係具有供乘客搭乘而將 其移送之皮帶；及至少在主框內使此皮帶循環之驅動系統

皮帶係相互地在第1循環路徑不同之部分，分別與搭乘皮 帶接觸’以驅動搭乘皮帶。 理想是，驅動皮帶係在第1循環路徑中，在至少乘客 搭乘於搭乘皮帶的區間的至少一部分，與搭乘皮帶接觸， 在該處將驅動力傳達至搭乘皮帶。 -7- (4) (4)1276599 理想是，爲了提昇驅動力的傳達效率，而在驅動皮帶 與搭乘皮帶的相互接觸之至少一方的面設置嚙合部。 又，對於所設置之複數個驅動皮帶，亦設置複數個驅 動機構。例如’設置使第1驅動皮帶循環之第1驅動機構' 及使第2驅動皮帶循環之第2驅動機構。藉此，能夠構成= 對於搭乘口、下降口的速度，增加中央部的速度之中間加 速型皮帶式乘客輸送機。例如，使用較以第1驅動機構所 循環的第1驅動皮帶的速度大之速度，藉由第2驅動機構來 使第2驅動皮帶循環。在此情況，搭乘皮帶係適用可朝循 環方向伸縮之構造者。 在此情況，爲了使搭乘皮帶的循環速度穩定地變遷， 而進一步在第1驅動皮帶接觸於搭乘皮帶的區域、與第2驅 動皮帶接觸於搭乘皮帶的區域之間，進一步設置接觸於搭 乘皮帶而賦予驅動力之至少一個滾筒。此滾筒之周速係設 定成較第1驅動皮帶的循環速度大、且較第2驅動皮帶的循 環速度小。理想爲設置複數個滾筒。各滾筒的周速係設定 成越接近第2驅動皮帶側者越大。用來使滾筒旋轉之驅動 力係由第1驅動皮帶或第2驅動皮帶的至少其中一方輸入。 又，亦可在第1驅動皮帶接觸於搭乘皮帶的區域、與 第2驅動皮帶接觸於搭乘皮帶的區域之間，設置接觸於搭 乘皮帶而賦予驅動力之至少一個中間驅動皮帶。 爲了使驅動皮帶彼此之間的速度變化圓滑，而第1驅 動皮帶、第2驅動皮帶及中間驅動皮帶係分別以在寬度方 向分割成複數個之分割帶所構成。各驅動皮帶之複數個分 -8- (5) (5)1276599 割帶係配置成沿著折返端的位置所相反沿著的方向平行且 相互地偏移之鋸齒狀。根據相鄰的驅動皮帶之分割帶的折 返端之位置所形成的鋸齒形狀彼此相互地嚙合配置。 中間驅動皮帶之速度係設定成較第1驅動皮帶的速度 大且較第2驅動皮帶的速度小。理想爲中間驅動皮帶係設 置複數個，各％間·驅動皮帶之周速係設定成越接近第2驅 動皮帶側越太‘:。:用來使中間驅動皮帶循環之驅動力係由第 1驅動皮帶或第:2驅動皮帶之至少其中一方供紿至中間驅動 皮帶。 又，第1驅動皮帶係著色有第1顏色、第2驅動皮帶係 著色有第2顏色，而至少一個滾筒或中間驅動皮帶著色有 第1顏色與第2顏色之中間顏色。在此情況，搭乘皮帶係以 透過其至少一部分，具有可供乘客確認的透光性者來構成 第1驅動皮帶、第2驅動皮帶、及至少一個滾筒或中間驅動 皮帶所著色之各顏色。 在滾筒或中間驅動皮帶設置有複數個之情況時，各滾 筒的周速或各中間驅動皮帶的循環速度係設定成越接近第 2驅動皮帶側者越大。又，複數個滾筒或複數個中間驅動 皮帶係著色成：伴隨著由第1驅動皮帶接近第2驅動皮帶， 由接近第1顏色的顏色變遷成接近第2顏色之顏色爲佳。 【實施方式】 以下參照各圖，說明本發明的實施形態之乘客輸送機 (6) (6)1276599 [第i實施形態] 具有使乘客搭乘而將其移送之皮帶；及至少使此皮帶 在主框內循環之驅動系統。皮帶係構成具有搭乘皮帶與驅 動皮帶之雙重構造。搭乘皮帶係沿著設置於主框內的第i 循環路徑循環。驅動皮帶係沿著設置於第1循環路徑的內 側之第2循環路徑循環。而驅動皮帶係藉由接觸於搭乘皮 帶的內周面之至少一部分，來將使搭乘皮帶循環用的驅動 力傳達至搭乘皮帶。驅動系統係包含用來產生使驅動皮帶 循環的驅動力之驅動機構。 首先，參照圖1至圖4，說明關於第1實施形態。乘客 輸送機全體結構如圖1所示。乘客輸送機1係具備使乘客搭 乘而將其移送之皮帶的皮帶式乘客輸送機。皮帶係藉由驅 動系統循環於主框2內。皮帶係以搭乘皮帶3與驅動皮帶4 所構成之雙重構造。 搭乘皮帶3係沿著設置於主框2內的預定循環路徑（第 1循環路徑）循環。驅動皮帶4係沿著設置於第1循環路徑 的內側之第2循環路徑循環移動。驅動皮帶4 ( 4a、4b、4c )係藉由接觸於搭乘皮帶3的內周面，來將使搭乘皮帶3循 環的驅動力傳達至搭乘皮帶3。又，乘客輸送機1係具備用 來驅動驅動皮帶4 ( 4a、4b、4c )之驅動機構5 ( 5a、5b、 5c) 在實施形態，如圖1及圖2所示的驅動皮帶4之導引手 段6係以導引滾筒等所構成。導引手段6係配置於主框2之 內部。導引手段6係包含賦予驅動皮帶4之適當的張力之張 - 10- (7) (7)1276599 力器。 驅動皮帶4係以沿著成爲搬運方向的主框2之長方向呈 直列地排列的方式，設置3條。相對於此，搭乘皮帶3係以 循環連續於乘客輸送機全長之1條皮帶所構成。各驅動皮 帶4a、4b、4c係在各循環路徑中的一部分，與搭乘皮帶3 接觸地配置。驅動皮帶4a、4b、4c係分別在與各搭乘皮 帶之接觸部，將驅動力傳達至搭乘皮帶3。第1驅動皮帶4a 係架掛於直徑大的折返滾筒8與直徑小的折返滾筒4f之間 。第2驅動皮帶4b係架掛於直徑小的一對折返滾筒4g之間 。第3驅動皮帶4c傲與第1驅動皮帶43的情況同樣地，架 掛於直徑大的折返滾筒8與直徑小的折返滾筒4 f之間。第 3驅動皮帶4 c在乘客輸送機的長方向，由中心位置與第1 驅動皮帶4a對稱地配置著。 第2驅動皮帶4b係配置於第1驅動皮帶4a與第3驅動皮 帶4c之間，捲掛第1驅動皮帶4a及第3驅動皮帶4c之折返 滾筒4f、與捲掛第2驅動皮帶4b之折返滾筒4g係配置成相 互相鄰。而搭乘皮帶3係架掛於配置於主框2的一端側之一 方側的折返滾筒8與配置於主框2的另一端側之另一方側的 折返滾筒8之間。 在圖1所示的實施形態，在搭乘皮帶3的循環路徑中乘 客所搭乘的部分之範圍內，驅動皮帶4係構成與搭乘皮帶3 接觸。亦可在搭乘皮帶3的歸路部分，驅動皮帶4與搭乘皮 帶3接近之區段，由驅動皮帶4將驅動力傳達至搭乘皮帶3 -11 - (8) 1276599 ^ 其次，參照圖1及圖2，說明關於用來驅動設置於主框 、 2的兩端部1A、1C之第1驅動皮帶4a的第1驅動機構5a、 及用來驅動第3驅動皮帶4c之第3驅動機構5c。再者，第3 驅動皮帶4c的構造係與第1驅動皮帶4a之構造相同，因此 ，第3驅動機構5c也與第1驅動機構5a相同。但其循環方 向爲相互相反之關係。 如圖1及圖2所示，第1驅動機構5 a係具有驅動滑輪7 鲁 。此驅軌滑輪7係設置成：在搭乘皮帶3的折返部3 a，與該 搭乘皮帶3嚙合。爲了確保該嚙合部的執行長度，第i驅動 皮帶4a係使用導引滾筒8 a，導引於驅動滑輪7。具體而言 ，如圖2所示，第1驅動皮帶4 a係由搭乘皮帶3的內周面分 離而沿者驅働滑輪7的外周面廷迴，藉由拆返滾筒8而再次 與ί合乘皮帶3重疊。導引滾筒8 a之旋轉軸係可自由旋轉地 安裝於主框2之適當部位。 乂 ’與驅動滑輪7冋軸地附設有定時滑輪9。在電動機 ® 1 〇的驅動軸1 0 a ’安裝定時滑輪1 0 b。而在定時滑輪」〇b與 疋時滑輪9之間架掛定時皮帶丨丨。亦可使用鏈齒代替定時 滑輪9、1 〇b，使用鏈條代替定時皮帶。 當連結構件10驅動定時皮帶丨丨時，與此同步，驅動滑 輪7旋轉。此結果，驅動皮帶4a被驅動，搭乘皮帶3循環 移動。搭乘皮帶3及驅動皮帶4a的各折返部係相互重疊捲 掛於折返滾筒8。因此，搭乘皮帶3係以與驅動皮帶h相 等的速度循環。 再者，第3驅動機構Sc也將第3驅動皮帶&驅動成與 - 12- (9) (9)1276599 搭乘皮帶3之移動速度相等。由各驅動皮帶4a、4b、4c將 驅動力傳達至ί合乘皮帶3的部分之結構如後所說明。 其次，說明關於第2驅動皮帶4 b。第2驅動皮帶4 b係 藉由設置於主框2的中央部1B的第2驅動機構5b所驅動。 如圖3所詳細顯示般，第2驅動機構5b係具偶複數個驅動 滾筒12及加壓滾筒13 〇 第2驅動皮帶4 b係在其循環軌道的一部分，受到驅動 滾筒1 2及加壓滾筒1 3所夾持。加壓滾筒1 3係藉由所附設的 彈簧I4之彈力，將第2驅動皮帶4b按壓於相對向的驅動滾 筒1 2。藉此，驅動力係由驅動滾筒1 2確實地傳達至第2驅 動皮帶4b 〇 各驅動滾筒1 2係與此同軸地附設有鏈齒1 5 a。又，:第2 驅動機構5b係進一步具備鏈齒1 5b、1 5c、1 5d。這些鏈齒 1 5 b、1 5 c、1 5 d係與鏈齒1 5 a —同地架掛無端狀鏈條1 6。 鏈齒15b係受到彈簧16a所支承，藉由彈簧16a的彈 力，對於鏈條1 6賦予張力。與鏈齒1 5 d同軸地安裝有定時 滑輪1 7。圖1及圖3所示的電動機1 8係具有安裝於驅動軸 1 8 a之定時滑輪18 b。而在此定時滑輪1 8 b與定時滑輪1 7之 間架掛有定時皮帶1 9。 當起動電動機18，而定時滑輪18b旋轉時，則與此同 步，鏈條1 6循環。此結果，驅動皮帶4b被循環，而驅動 力被傳達至搭乘皮帶3。包含於第2驅動機構5b之驅動滾 筒12、定時滑輪17、18b等之直徑係設定成··第2驅動皮 帶4 b的移動速度形成與搭乘皮帶3之移動速度枏等。 -13- (10) (10)1276599 爲了使驅動皮帶4a、4b、4c同步，亦可加以機構性 地連結。在此情況，如圖1之2點虛線所示，設置連結折返 滾筒4 f、4 g之驅動皮帶連結用的定時皮帶4 e。藉此，亦可 相互補足驅動力之不足。即，電動機〗8的動力由第2驅動 皮帶4 b經由定時皮帶4 e進一步傳達至第1驅動皮帶4 a及 第3驅動皮帶4c。此結果，與這些驅動皮帶4a、4b、4c接 觸的搭乘皮帶3係藉由設置於第1驅動機構5 a與第3驅動機 構5 c的電動機1Ό及設置於第2驅動機構5 b的電動機1 8所產 生的穩定之驅動力來循環。 再者，鏈條16係亦可使用其他形式的無端動力傳達構 件例如定時皮帶或具有齒之皮帶。定時皮帶1 1、1 9亦可使 用使用其他形式的無端動力傳達構件例如鏈條或具有齒之 皮帶。在此情況，各鏈齒1 5 a、1 5 b、1 5 c、1 5 d或定時滑 輪9、1 Ob、17、18置換成適合於該無端動力傳達構件之定 時滑輪或鏈齒、具有齒之滑輪。 其次，參照圖4，說明關於由驅動皮帶4 ( 4a、4b、4c )將驅動力傳達至搭乘皮帶3的機構之結構。圖4係包含沿 著圖1中的IV-IV線的剖面之斜視圖。在圖1， 「IV-IV」 的顯示係附於複數處所，這些複數處所之構造實質上相互 相同。 如圖4所示，皮帶式乘客輸送機1係沿著循環方向，在 搭乘皮帶3的雨側具有導軌20。導軌20係具有隧道型鋼同 樣的剖面形狀。再者，導軌20係僅設置於搭乘皮帶3與驅 動皮帶4並進之區段，未設置於其他區段。 -14- (11) (11)1276599 搭乘皮帶3係一般使用於以往的皮帶式乘客輸送機者 相同，剖面形狀呈薄矩形之所謂平皮帶。又，如圖4所示 ，驅動皮帶4係形成剖面呈薄矩形之所謂平皮帶。在接觸 於搭乘皮帶3中乘客所搭乘側之下面的驅動皮帶4之下側’ 水平地設置有支承板2 1。支承板2 1係支承驅動皮帶4。 減低在與驅動皮帶4之間所產生的摩擦力之手段謀求 於支承板2 1爲佳、。作爲減低摩擦力的手段，如圖4所示， 除了在支承板2 1設置可自由地旋轉的支承滾筒2 2的方法外 ，還具有在支承板2 1上設置低摩擦的樹脂披覆層之方法。 由驅動皮帶4傳達至搭乘皮帶3的驅動力之傳達效率係 依存於驅動皮帶4與搭乘皮帶3之間的嚙合效率或摩擦係數 、和作用於搭乘皮帶3與驅動皮帶4之相互間的按壓力。 爲了提昇嚙合效率，軟質層3 d設置於搭乘皮帶3之至 少與驅動皮帶4接觸的面。在本實施形態，搭乘皮帶3係藉 由芯材3 c與覆蓋此芯材3 c的周圍之軟質層3 d所構成。 一方面，驅動皮帶4係具有：爲了增加抓力，而設置 例如凹凸等之面粗糙度粗之內周面4d。粗的內周面4d係 因與搭乘皮帶3之軟質層3d接觸而嚙合，所以可確實地在 兩者之間進行驅動力傳達。 芯材3 c係沿著搭乘皮帶3之寬度方向配置，維持平皮 帶剖面形狀。芯材3 c係防止搭乘皮帶3由支承板2 1分離。 芯材3 c係以不會有損搭乘皮帶3之屈曲性的方式，在搭乘 皮帶3的循環方向，隔著一定間隔水平地排列設置著複數 個。 -15- (12) (12)1276599 在搭乘皮帶3的兩側之緣部3 b朝寬度方向突出的芯材 3c，可自由旋轉地安裝著滾筒3e。滾筒3e係嵌入至導軌 2 0的凹部，予以導引搭乘皮帶3之循環移動。再者，導軌 2 〇係除了隧道型鋼之外，亦可爲L型鋼、1型鋼或H型鋼 。搭乘皮帶3及驅動皮帶4係爲了提昇兩者間之嚙合效率， 亦可如第2實施形態之個6所示般加以構成。 驅動皮帶4係內裝有作爲延伸限制構件之複數個吊索 4h，吊索4h係爲補強用鋼絲，沿著循環方向埋入於驅動 皮帶4，以維持驅動皮帶4的長方向之強度。因此，即使受 到乘客搭載於搭乘皮帶3，使負荷施加於驅動皮帶4之情況 ，也不會產生驅動皮帶4破損或延伸之情事。 在驅動皮帶4與搭乘皮帶3之間所產生的嚙合力係大幅 度地依存於：受到乘客搭乘於搭乘皮帶3將搭乘皮帶3朝驅 動皮帶4按壓之力。由於更多的乘客搭乘於搭乘皮帶3，越 可提升由搭乘皮帶3傳達至驅動皮帶4之傳達效率，故非常 理想。 作用於驅動皮帶4與搭乘皮帶3之間的按壓力亦依存於 搭乘皮帶3的自重特別是乘客所搭乘的範圍之搭乘皮帶3的 自重、及作用於搭乘皮帶3本身之張力。特別是在搭乘皮 帶3的折返部分，作用於驅動皮帶與搭乘皮帶之間的按壓 力係大幅度地依存於作用於搭乘皮帶3全體之張力。 因此’即使在乘客未搭乘於搭乘皮帶3之情況，由驅 動皮帶4可確實地將驅動力傳達至搭乘皮帶3地，設置賦予 搭乘皮帶3張力之手段爲佳。作爲張力賦予手段，能夠使 -16- (13) 1276599 I 用在以往之皮帶式乘客輸送機設置於手扶帶之驅動裝置的 • 機構。但，藉由張力賦予手段賦予至搭乘皮帶3之張力係 亦可比起以往的皮帶式乘客輸送機之搭乘皮帶大幅度縮小 。因此，施加於搭乘;皮帶3之負、荷僅有稍許。. 皮帶式乘客輸送機1係如圖1所示，支承導引搭乘皮帶 3之支承滾筒2 3位於導軌2 0及支承板2 1中斷之區段。支承 滾筒23亦可置換成適當形狀之導軌。 φ 又，在乘客不搭乘之範圍的主框內，至少搭乘皮帶3 屈曲的區段，適宜地設置導引滾筒或滑輪。再者.，在設置 於以往的皮帶驅動裝置般的張力賦予手段設置於搭乘皮帶 之情況時，在搭乘皮帶屈曲之區段的附近，設置賦予張力 之張力器滾筒。 若根據本貧施形態的話，可獲得以下般的優良效果。 在使用於乘客輸送機之皮帶，被同時要求可承受高度 張力之機械強度、與乘客搭乘時之觸感與外觀等之質感。 φ 在使用以往的皮帶驅動裝置的狀態下，無法同時達到上述 要求。相對於此，若根據本實施形態之皮帶式乘客輸送機 1的話，驅動皮帶4維持高度的機械強度即可，對於循環方 向之搭乘皮帶3的機械強度亦可低。 電動機1 0、1.8之動力係被傳.達至驅動皮帶4，以該動 力使驅動皮帶4循環移動。搭乘皮帶3係與該驅動皮帶4嚙 合，僅與該驅動皮帶4 一體地循環移動。即，搭乘皮帶3係 由於幾乎不會承受對於循環方向之負荷，故機械強度亦可 低。 -17- (14) 1276599 因此，在皮帶式乘客輸送機1，能夠設計重視質感之 ’ 搭乘皮帶3。再者，搭乘皮帶3的剖面形狀之維持係藉由設 置如圖2所示的芯材3c，可不需要犧牲質感而能容易地達 又，驅動皮帶4係由於可使用剖面形狀單純之平皮帶 ，故容易成形。驅動皮帶4係因實質上確保循環方向之強 度即可，所以亦可容易確保強度。且，捲掛驅動皮帶4之 φ 滾筒8的形狀亦可爲單純者。 由於能夠將搭乘皮帶3的全體形狀作成與以往形狀相 同，故對於乘客而言不會有不舒服感，亦可與以往相同地 確保安全性。且，由於搭乘皮帶3與驅動皮帶4不會相對地 滑動，故當緊急停止時，搭乘皮帶3不會空轉，而可確保 與以往相同之安全性。 又，驅動力係由於由驅動皮帶4 a、4 b、4 c，以複數個 處所傳達至搭乘皮帶3，故可防止過大的負荷施加至驅動 φ 皮帶4a、4b、4c之其中任一個。換言之，即使搭乘皮帶3 的全長無論變得多長，藉由增加驅動皮帶4之數量，即可 供給充分之驅動力。 . 再者，根據本發明所構成的驅動皮帶4及驅動機構5的 結構亦可在一個乘客輸送.機設置一個。在實施形態，第1 驅動機構5a與第2驅動機構5b具有不同之構造，但不限於 此。亦可所有複數個驅動機構5爲相同構造。 [第2實施形態] -18- (15) (15)1276599 關於第2實施形態之皮帶式乘客輸送機3 1，參照圖5及 圖6進行說明。乘客輸送機3 1係具有：中間部分3 1 B之搭 乘皮帶33的速度較成爲搭乘口或下降口的端部31A、31C 之速度大的「中間加速型」者。在第2實施形態，具有與 第1實施形態相同功能之構成要素係賦予相同符號，省略 其重複的說明。 如圖5所示，乘客輸送機31係具備：搭乘皮帶33、第1 驅動皮帶34a、第2驅動皮帶34b、與第3驅動皮帶34c。搭 乘皮帶33係供乘客直接搭乘之皮帶，沿著設置於主框32內 的循環路徑循環移動。第1驅動皮帶34a及第3驅動皮帶 3 4 c係配置靠近於成爲搭乘口或下降口側的乘客輸送機之 端部3 1 A、3 1C，以驅動搭乘皮帶33。第2驅動皮帶34b係 配置於乘客輸送機3 1之中間部分3 1 B，以驅動搭乘皮帶3 3 〇 第1驅動皮帶34a及第3驅動皮帶34c係作爲端部31A、 3 1C較短之區段’沿著搬運方向延伸。在搭乘口側，驅動 皮帶與搭乘皮帶3 3 —同被折返而導引至滾筒8上側。在下 降口側，驅動皮帶與搭乘皮帶3 3 —同被折返而導引至滾筒 8下側。乘客輸送機3 1的幾乎所有區間被第2驅動皮帶3 4b 所佔據。再者，第2驅動皮·帶34b之結構亦可作成：分成 複數個，以分擔對於搭乘皮帶3 3之驅動力。 各驅動皮帶34a、34b、34c係藉由具有與先前參照圖 1及圖2作了說明之第1驅動機構5a大致相同之結構的驅動 機構3 5 (弟1驅動機構3 5 a、第2驅動機構3 5 b、第3驅動機 -19- (16) (16)1276599 構35c )來驅動。此時，第1驅動皮帶34a係以速度VI來循 環，第2驅動皮帶34b係以較速度VI更大的速度V2來循環 〇 爲了在第1驅動皮帶34a與第2驅動皮帶34b之間設置 速度差，而適宜地設定設置於各驅動皮帶34a、34b滾筒 鏈齒或定時滑輪之直徑等。再者，如圖5所示的第2驅動機 構3 5b係如圖3所示的第2驅動機構5b、與加壓滾筒13和驅 動滾筒12之位置關係爲夾持搭乘皮帶33形成上下相反。如 圖5所示的第2驅動機構35b之驅動滾筒12係在外周具有齒 槽。如圖6所示，第2驅動皮帶34b之外周面係形成齒槽 3 4d，與驅動滾筒12之齒槽嚙合。 搭乘皮帶33係使用至少在循環方向，W((V2/V1)-1 ) X 1 00%彈性地延伸之構件。在乘客輸送機3 1，第1驅動 皮帶34a、第2驅動皮帶34b、及第3驅動皮帶34c係分別以 速度VI、V2、VI來驅動。因伴隨此，搭乘皮帶33延伸， 所以在端部3 1 A、3 1 C附近以速度v 1移動，而在中間部分 3 1B以速度V2移動。 如此’能夠在搭乘皮帶3 3使用伸縮性構件之理由係在 第1實施形態的效果也作過說明般，搭乘皮帶3 3在循環方 向不需要大的強度之故。 如圖6所示’在乘客輸送機31所使用的搭乘皮帶33也 與以往的皮帶式乘客輸送機所使用者同樣地成形爲剖面薄 之矩形之平皮帶。搭乘皮帶3 3的寬度方向之兩側緣部係藉 由導引滾筒3

彈性材料所構成的披覆層33c內。 在第2實施形態，在第1驅動皮帶3 4 a的速度V Γ與第2 驅動皮帶3 4b之速度V2之間產生差。因此，需要防止搭 乘皮帶3 3與驅動皮帶3 4 a、3 4 b、3 4 c之間的滑動。因而被 要求在搭乘皮帶3 3與驅動皮帶3 4 a、3 4 b、3 4 c之間驅動力 之更高的傳售效率，也就是搭乘皮帶3 3與驅動皮帶3 4 a、 34b、34c之間的確實嚙合。 因此’在搭乘皮帶3 3的內周面形成齒槽3 3d，在驅勸 皮帶34a、3 4b、3 4c之外周面形成齒槽34d。此時，齒槽 3 3 d及齒槽3 4 d係分別形成互補之形狀。這些齒槽3 3 d、 3 4 d之形狀係除了在搭乘皮帶3 3、驅動皮.帶3 4 a、3 4b、 34c的表面實施如圖6所示般的凹凸形狀以外，尙可作成 三角波浪狀的山與谷之形狀、齒輪的齒槽般形狀。 芯材3 3 a係如圖6所示，具有朝搭乘皮帶3 3的內周面 側突出之芯材突出部3 3 e。此芯材突出部3 3 e係與驅動皮 帶34a、34b、34c之齒槽34d嚙合。藉此，因芯材3 3a可 穩固地嚙合於球投入機構3 4，故可提升驅動力之傳達效率 -21 - (18) 1276599 再:者，芯材突出部3 3 e之前端形狀係除了形成配合驅 • 動皮帶34a、34b、34c之齒槽34d的槽形狀之形狀以外’ 亦可將芯材突出部3 3 e之前端形狀作成方形’而設置芯材 突出部33e嚙合於驅動皮帶34a、. 34b、34c之齒槽34d的 矩形溝槽。又，如圖6所示的搭乘皮帶3 3與驅動皮帶34 a、 3 4 b之嚙合構造係當然能適用於第1實施形態。 爲了提高循環方向的強度及剛性，而將鋼帶3 4 e埋入 φ 於驅動皮帶34a、34b、34c的內部。此鋼帶3.4e亦可爲第1 實施形態所示的補強用吊索4h。再者，與圖所示的驅動皮 帶4相較，驅動皮帶34a、34b、34c係在於如圖6所示，設 置齒槽34d之表面形狀、及內裝作爲補強材之鋼帶34e的 點，與驅動皮帶4不同。 搭乘皮帶33係在由第1驅動皮帶34a上移行至第2驅動 皮帶34b之際，急劇地延伸，由第2驅動皮帶34b上移行至 第3驅動皮帶34c之際急劇地收縮。因此，爲了防止搭乘 φ 皮帶33劣化，防止局部的荷重施加於搭乘皮帶33爲佳。其 一例，將如圖6所示的.速度變更手段37設置於第1驅動皮帶 3 4a與第2驅動皮帶34b之間。速度變更手段37係爲了將搭 乘皮帶33之速度由VI逐漸地變化成V2而設置的。 以下，參照圖6更詳細地說明速度變更手段37。如圖6 所示’速度變更手段37係具有複數個滾筒組38。滾筒組38 係以具有與驅動皮帶大致相同寬度之寬廣滾筒的驅動滾筒 3 8

旋轉周速，係設定成：由第2驅動皮帶3 4 b的旋轉速度至 第3驅動皮帶3 4x的旋轉速度爲止，逐漸地變慢。即，以 -23- (20) (20)1276599 折返滾筒及驅動滾筒作爲基準的傳達滾筒之直徑比率設定 成逐漸變大。 傳達滾筒 38bl、 38b2、 38b3、 38b4、 38b5、 38b6、 3 8 b 7的外周面係若驅動力相互地傳達的程度會產生摩擦力 的話，亦可爲作成平滑。具體而言，各傳達滾筒的外周面 係以密著度高之軟質材料來形成爲佳。又，亦可在傳達滾 筒的外周面設置齒槽，在傳達滾筒38bl、38b2、38b3、 38b4、38b5、38b6、38b7之間藉由齒槽彼此嚙合，來傳達 驅動力。 因速度變更手段37具有上述結構，所以驅動滾筒38a3 、3 8 a4之周速係越接近第2驅動皮帶3 4 b側者變得越大。 以接近第1驅動皮帶34a側的驅動滾筒38a3之，.周速係.變得 較第1驅動皮帶34a的循環速度稍大，且較接近第2驅動皮 帶34b側的驅動滾筒38a4較第2驅動皮帶34b的循環速度小 的方式，設定各傳達滾筒之直徑。 再者，在驅動滾筒爲2個以上之情況也相同。又，若 在第1驅動皮帶34a至第2驅動皮帶34b之間，驅動滾筒的 周速呈階段性地變化的話，折返滾筒4f、4g間之驅動滾

passenger conveyor that is used as a passenger to be used, and in particular, [Prior Art] A belt type used as an electric walkway Endless loop belt. The endless endless belt is supported by a plurality of guide rollers between the landing ports, and the ring. Conventional passenger conveyors have a structure in which a pulley is arranged to drive a belt. Drive, the majority of the movement is near the mouth. The passenger conveyor has a hand strap that is prepared as a grip during riding. The hand strap is an endless loop. The strap is looped from the drop to the drop port along the drop to the ride. The hand strap is driven at the same speed as the belt by being placed on the conveyor mechanism. It is generally known that the hand strap is clamped to the drive roller and the pressure roller to hold the hand strap. In recent years, in order to improve the passenger's transportation efficiency, the belt speed near the mouth and the vicinity of the lowering port is an intermediate acceleration belt type with a belt speed at the middle. For example, the Japanese Patent No. 3 3 0 8 2 8 8 The electric walkway has a drive mechanism. The passenger conveyor is provided with a prayer seat that is placed on the belt from the ride to the bottom by the drive unit, and is mounted on the ride or the lower support, so that the passenger is hung on the railing. The hand rail is moved, and the way of returning from the inside, the hand strap drive in the device, and the driving mechanism between the hand straps are also visible by the friction force, and the passenger conveyor is in the middle of the ride. The "conveyor (2) (2) 1276599" described in the description has a low-speed transfer unit with a slow moving speed and a high-speed transfer unit with a fast moving speed. This conveying device achieves the intermediate acceleration type by transferring the passenger from the low speed transfer portion to the high speed transfer portion or from the high speed transfer portion to the low feed transfer portion. Further, the "electricized walkway" described in Japanese Laid-Open Patent Publication No. Hei 7-23-28-85 is arranged in a plurality of belts having different transfer speeds. Retractable Most of the telescopic pallets are hung on the entire belt. The telescopic pallet is driven by the belt to circulate. This "electricized walkway" achieves an intermediate acceleration type by expanding and contracting the telescopic pallet in response to the speed of each belt. SUMMARY OF THE INVENTION However, when the passenger conveyor becomes long as the transport distance becomes long, the burden on the belt becomes large. Therefore, there is a case where a sufficient driving force cannot be transmitted only by the driving portion disposed in the belt folding portion. For example, the belt oscillates back and forth. Such a problem is not only present in the belt type electric walkway, but also a common problem of the entire belt conveyor having a long moving distance. As described above, even in the case where the belt is long, the belt can be gripped by the driving roller and the pressure roller, and frictional force is generated to drive the belt, but the belt is subjected to excessive tension or surface pressure due to operating conditions. Therefore, there will be a drop in belt life. Further, in the passenger conveyor classified into the intermediate acceleration type, as in the "conveying device" described in Japanese Patent Publication No. 3 3 0 8 9 8 , the transfer unit having different moving speeds is generated. The speed of the transfer unit changes to no longer. Therefore, in the transfer department, there are also passengers shaking or falling, which is not ideal for passenger safety of -6-(3) (3)1276599. Further, in the "electricized walk" described in Japanese Laid-Open Patent Publication No. Hei 7-23 2 8 8 5, when the telescopic pallet is extended, there is a possibility that the telescopic pallet cannot be physically shortened. Therefore, for a belt type passenger conveyor having a long transportation distance, it is required to have a small burden on the belt portion, which can be driven correctly and smoothly; and an intermediate acceleration type belt passenger that ensures safety for passengers during operation. Conveyor. [Means for Solving the Problem] The belt type passenger conveyor of the present invention is a belt having a belt for passengers to carry and which is transported; and a drive system for circulating the belt at least in the main frame. The construction of the belt has a dual construction of a belt and a drive belt. The ride belt loops along the first circulation path provided in the main frame. The drive belt is circulated along a second circulation path provided inside the first circulation path. Further, the drive belt transmits the driving force for circulating the belt to the boarding belt by contacting at least a part of the inner circumferential surface of the boarding belt. The drive system includes a drive mechanism that generates a driving force for circulating the drive belt. It is better to set a plurality of drive belt systems. In this case, a plurality of driving belts are in contact with each other in the portion different from the first circulation path to drive the riding belt. Preferably, the drive belt is in the first circulation path, and at least a part of the section where the passenger rides on the boarding belt contacts the boarding belt, and the driving force is transmitted to the boarding belt. -7- (4) (4) 1276599 It is preferable to provide an engaging portion on at least one surface of the driving belt and the boarding belt in order to improve the transmission efficiency of the driving force. Further, a plurality of driving mechanisms are also provided for the plurality of driving belts provided. For example, 'the first drive mechanism that circulates the first drive belt is provided' and the second drive mechanism that circulates the second drive belt. Thereby, it is possible to configure an intermediate acceleration type belt type passenger conveyor that increases the speed of the center portion with respect to the speed of the boarding pass and the descending port. For example, the second drive belt is circulated by the second drive mechanism at a speed higher than the speed of the first drive belt that is circulated by the first drive mechanism. In this case, the rider belt is suitable for a structure that can expand and contract in the circulation direction. In this case, in order to stably change the circulation speed of the boarding belt, the contact area between the first driving belt contacting the boarding belt and the area where the second driving belt is in contact with the boarding belt is further provided in contact with the boarding belt. At least one roller that imparts a driving force. The peripheral speed of the drum is set to be larger than the circulation speed of the first drive belt and smaller than the circulation speed of the second drive belt. It is desirable to provide a plurality of rollers. The peripheral speed of each drum is set to be larger as it approaches the second drive belt side. The driving force for rotating the drum is input from at least one of the first drive belt or the second drive belt. Further, at least one intermediate drive belt that is in contact with the ride belt and is provided with a driving force may be provided between a region where the first drive belt contacts the boarding belt and a region where the second drive belt contacts the boarding belt. In order to make the speed change between the drive belts smooth, the first drive belt, the second drive belt, and the intermediate drive belt are respectively divided into a plurality of divided belts in the width direction. A plurality of points of each drive belt -8- (5) (5) 1276599 The cutting belts are arranged in a zigzag shape which is parallel and offset from each other along the opposite direction of the position of the folded end. The zigzag shapes formed by the positions of the folded ends of the divided belts of the adjacent drive belts are engaged with each other. The speed of the intermediate drive belt is set to be higher than the speed of the first drive belt and smaller than the speed of the second drive belt. It is desirable to set a plurality of intermediate drive belt systems, and the peripheral speed of each of the % drive belts is set to be closer to the second drive belt side. : The driving force for circulating the intermediate drive belt is supplied to at least one of the first drive belt or the (2) drive belt to the intermediate drive belt. Further, the first driving belt is colored with the first color, the second driving belt is colored with the second color, and at least one of the rollers or the intermediate driving belt is colored with the intermediate color of the first color and the second color. In this case, the boarding belt passes through at least a part thereof and has a light transmissive property for the passenger to confirm, and the colors of the first driving belt, the second driving belt, and the at least one drum or the intermediate driving belt are colored. In the case where a plurality of rollers or intermediate drive belts are provided, the peripheral speed of each roller or the circulation speed of each intermediate drive belt is set to be larger as it approaches the second drive belt side. Further, the plurality of rollers or the plurality of intermediate drive belts are colored such that the color close to the first color is changed to a color close to the second color as the first drive belt approaches the second drive belt. [Embodiment] Hereinafter, a passenger conveyor (6) (6) 1276599 according to an embodiment of the present invention will be described with reference to the drawings. [Embodiment Embodiment] A belt having a passenger boarded and transported; and at least the belt is mainly provided The drive system in the loop. The belt system has a dual construction with a riding belt and a driving belt. The belt is looped along the i-th cycle path provided in the main frame. The drive belt system circulates along the second circulation path provided on the inner side of the first circulation path. On the other hand, the drive belt transmits the driving force for circulating the belt to the boarding belt by contacting at least a part of the inner peripheral surface of the boarding belt. The drive system includes a drive mechanism for generating a driving force for circulating the drive belt. First, the first embodiment will be described with reference to Figs. 1 to 4 . The overall structure of the passenger conveyor is shown in Figure 1. The passenger conveyor 1 is a belt type passenger conveyor having a belt for transporting passengers and transferring them. The belt loops through the main frame 2 by the drive system. The belt is constructed in a double structure of the riding belt 3 and the driving belt 4. The boarding belt 3 is circulated along a predetermined circulation path (first circulation path) provided in the main frame 2. The drive belt 4 is cyclically moved along a second circulation path provided inside the first circulation path. The drive belt 4 (4a, 4b, 4c) transmits the driving force for circulating the boarding belt 3 to the boarding belt 3 by coming into contact with the inner peripheral surface of the boarding belt 3. Further, the passenger conveyor 1 is provided with drive mechanisms 5 (5a, 5b, 5c) for driving the drive belts 4 (4a, 4b, 4c). In the embodiment, the guide belts 4 are shown in Figs. 1 and 2 The guiding means 6 is constituted by a guide roller or the like. The guiding means 6 is disposed inside the main frame 2. The guiding means 6 comprises a sheet - 10- (7) (7) 1276599 force that imparts the proper tension to the drive belt 4. The drive belts 4 are provided in such a manner that they are arranged in a line in the longitudinal direction of the main frame 2 which is a conveyance direction. On the other hand, the boarding belt 3 is constituted by one belt that is continuously continuous over the entire length of the passenger conveyor. Each of the drive belts 4a, 4b, and 4c is a part of each of the circulation paths, and is disposed in contact with the boarding belt 3. The drive belts 4a, 4b, and 4c transmit the driving force to the boarding belt 3 at the contact portion with each of the boarding belts. The first drive belt 4a is hung between the large-diameter folding drum 8 and the small-diameter folding drum 4f. The second drive belt 4b is hung between the pair of folding rollers 4g having a small diameter. Similarly to the case of the first drive belt 43, the third drive belt 4c is hung between the folding drum 8 having a large diameter and the folding drum 4f having a small diameter. The third drive belt 4c is disposed symmetrically with the first drive belt 4a from the center position in the longitudinal direction of the passenger conveyor. The second drive belt 4b is disposed between the first drive belt 4a and the third drive belt 4c, and retracts the folding drive drum 4f of the first drive belt 4a and the third drive belt 4c and the second drive belt 4b. The drums 4g are disposed adjacent to each other. On the other hand, the take-up belt 3 is hung between the folding drum 8 disposed on one side of the one end side of the main frame 2 and the folding drum 8 disposed on the other side of the other end side of the main frame 2. In the embodiment shown in Fig. 1, the drive belt 4 is configured to come into contact with the boarding belt 3 within a range in which the passenger rides in the circulation path of the boarding belt 3. Alternatively, in the returning portion of the belt 3, the drive belt 4 and the boarding belt 3 are in a section close to each other, and the driving force is transmitted from the driving belt 4 to the boarding belt 3 -11 - (8) 1276599 ^ Next, referring to FIG. 1 and 2. The first drive mechanism 5a for driving the first drive belt 4a provided at both end portions 1A and 1C of the main frame 2, and the third drive mechanism 5c for driving the third drive belt 4c will be described. Further, since the structure of the third drive belt 4c is the same as that of the first drive belt 4a, the third drive mechanism 5c is also the same as the first drive mechanism 5a. However, their circulation directions are opposite to each other. As shown in Figs. 1 and 2, the first drive mechanism 5a has a drive pulley 7 Lu. The drive rail pulley 7 is provided to be engaged with the boarding belt 3 at the turn-back portion 3a of the boarding belt 3. In order to secure the execution length of the engaging portion, the i-th drive belt 4a is guided to the drive pulley 7 by using the guide roller 8a. Specifically, as shown in FIG. 2, the first drive belt 4a is separated from the inner peripheral surface of the boarding belt 3, and is pressed back along the outer peripheral surface of the driver's drive pulley 7, and is again retracted by the drum 8 By the belt 3 overlap. The rotating shaft of the guide roller 8a is rotatably attached to an appropriate portion of the main frame 2. A timing pulley 9 is attached to the drive pulley 7 to the shaft. The timing pulley 1 0 b is mounted on the drive shaft 1 0 a ' of the motor ® 1 。. The timing belt 架 is hung between the timing pulley 〇b and the 滑轮 pulley 9. It is also possible to use a chain tooth instead of the timing pulley 9, 1 〇b, and a chain instead of a timing belt. When the joint member 10 drives the timing belt loop, in synchronization with this, the drive pulley 7 rotates. As a result, the drive belt 4a is driven and the ride belt 3 is circulated. Each of the folding portions of the belt 3 and the driving belt 4a are overlapped and wound around the folding drum 8. Therefore, the boarding belt 3 is circulated at a speed equal to that of the driving belt h. Further, the third drive mechanism Sc also drives the third drive belt &le to be equal to the movement speed of the - 12-(9) (9) 1276599 riding belt 3. The structure in which the driving force is transmitted to each of the driving belts 4a, 4b, 4c to the portion of the yucking belt 3 will be described later. Next, the second drive belt 4b will be described. The second drive belt 4b is driven by the second drive mechanism 5b provided in the central portion 1B of the main frame 2. As shown in detail in Fig. 3, the second drive mechanism 5b is provided with a plurality of drive rollers 12 and a pressure roller 13 〇 the second drive belt 4 b is attached to a part of its circulation track, and is driven by the roller 1 2 and the pressure roller. 1 3 clamped. The pressure roller 13 presses the second drive belt 4b against the opposing drive roller 12 by the elastic force of the attached spring I4. Thereby, the driving force is reliably transmitted from the driving roller 12 to the second driving belt 4b. The driving rollers 12 are coaxially attached with the fastener elements 15a. Further, the second drive mechanism 5b further includes sprocket 15b, 15c, and 15d. These sprocket teeth 1 5 b, 1 5 c, and 15 5 are spliced with the sprocket 1 5 a in the same place as the endless chain 16 . The sprocket 15b is supported by the spring 16a, and the tension of the chain 16 is imparted by the spring force of the spring 16a. A timing pulley 17 is mounted coaxially with the sprocket 15d. The motor 18 shown in Figs. 1 and 3 has a timing pulley 18b attached to the drive shaft 18a. A timing belt 19 is hung between the timing pulley 18b and the timing pulley 17. When the motor 18 is started and the timing pulley 18b is rotated, the chain 16 is circulated in synchronization with this. As a result, the drive belt 4b is circulated, and the driving force is transmitted to the boarding belt 3. The diameters of the drive roller 12, the timing pulleys 17, 18b, and the like included in the second drive mechanism 5b are set such that the moving speed of the second drive belt 4b forms a moving speed 搭乘 or the like of the boarding belt 3. -13- (10) (10) 1276599 In order to synchronize the drive belts 4a, 4b, 4c, they may be mechanically coupled. In this case, as shown by the dotted line in Fig. 1, a timing belt 4 e for connecting the drive belts of the folding rollers 4 f and 4 g is provided. In this way, it is also complementary to the lack of sufficient driving force. That is, the power of the motor 8 is further transmitted from the second drive belt 4b to the first drive belt 4a and the third drive belt 4c via the timing belt 4e. As a result, the boarding belt 3 that is in contact with the drive belts 4a, 4b, and 4c is provided by the motor 1 provided in the first drive mechanism 5a and the third drive mechanism 5c, and the motor 1 provided in the second drive mechanism 5b. The resulting stable driving force is cycled. Further, the chain 16 can also use other forms of endless power transmitting members such as timing belts or belts with teeth. Timing belts 1 1 and 19 can also use other forms of endless power transmission members such as chains or belts with teeth. In this case, each of the sprocket 1 5 a, 1 5 b, 1 5 c, 15 5 or the timing pulley 9, 1 Ob, 17, 18 is replaced with a timing pulley or a sprocket suitable for the endless power transmitting member, Tooth pulley. Next, a configuration of a mechanism for transmitting a driving force to the boarding belt 3 by the driving belt 4 (4a, 4b, 4c) will be described with reference to Fig. 4 . Fig. 4 is a perspective view showing a section taken along the line IV-IV in Fig. 1. In Fig. 1, the display of "IV-IV" is attached to a plurality of spaces, and the structures of these plural spaces are substantially identical to each other. As shown in Fig. 4, the belt type passenger conveyor 1 has a guide rail 20 on the rain side of the boarding belt 3 along the circulation direction. The guide rail 20 has the same cross-sectional shape as the tunnel profile steel. Further, the guide rail 20 is provided only in a section in which the boarding belt 3 and the driving belt 4 are advanced, and is not provided in other sections. -14- (11) (11) 1276599 The belt 3 system is generally used in the same way as the conventional belt type passenger conveyor. The so-called flat belt has a thin rectangular cross section. Further, as shown in Fig. 4, the drive belt 4 is formed as a so-called flat belt having a thin rectangular cross section. A support plate 21 is horizontally disposed in contact with the lower side of the drive belt 4 below the side on which the passenger is riding in the boarding belt 3. The support plate 2 1 supports the drive belt 4. It is preferable to reduce the frictional force generated between the drive belt 4 and the support plate 2 1 . As a means for reducing the frictional force, as shown in FIG. 4, in addition to the method of providing the supportable plate 2 2 which is freely rotatable on the support plate 21, a resin coating layer having a low friction is provided on the support plate 2 1. method. The transmission efficiency of the driving force transmitted from the driving belt 4 to the boarding belt 3 depends on the meshing efficiency or the friction coefficient between the driving belt 4 and the boarding belt 3, and the pressing force acting between the boarding belt 3 and the driving belt 4 . In order to improve the meshing efficiency, the soft layer 3d is disposed on the surface of the boarding belt 3 that is at least in contact with the drive belt 4. In the present embodiment, the boarding belt 3 is composed of a core material 3c and a soft layer 3d covering the periphery of the core material 3c. On the other hand, the drive belt 4 has an inner peripheral surface 4d having a rough surface roughness such as a concavity and convexity in order to increase the grip force. Since the thick inner peripheral surface 4d is engaged with the soft layer 3d of the boarding belt 3, the driving force can be reliably transmitted between the two. The core material 3c is disposed along the width direction of the boarding belt 3, and maintains the cross-sectional shape of the flat belt. The core material 3 c prevents the boarding belt 3 from being separated by the support plate 2 1 . The core material 3c is arranged in a plurality of horizontally at regular intervals in the circulation direction of the boarding belt 3 so as not to impair the flexibility of the boarding belt 3. -15- (12) (12) 1276599 The drum 3e is rotatably attached to the core member 3c which protrudes in the width direction from the edge portion 3b of both sides of the belt 3. The drum 3e is fitted into the recess of the guide rail 20, and guides the cyclic movement of the boarding belt 3. Furthermore, the guide rail 2 can be L-shaped steel, 1 type steel or H-shaped steel in addition to the tunnel profile steel. The belt 3 and the drive belt 4 are configured to improve the meshing efficiency between the two, as shown in the sixth embodiment. The drive belt 4 is provided with a plurality of slings 4h as extension limiting members, and the slings 4h are reinforcing wires which are embedded in the driving belt 4 in the circulation direction to maintain the strength of the driving belt 4 in the longitudinal direction. Therefore, even if a passenger is mounted on the boarding belt 3 and a load is applied to the driving belt 4, the driving belt 4 is not broken or extended. The meshing force generated between the drive belt 4 and the boarding belt 3 largely depends on the force that the passenger rides on the boarding belt 3 to press the boarding belt 3 toward the driving belt 4. Since more passengers are riding on the belt 3, the communication efficiency transmitted from the boarding belt 3 to the driving belt 4 can be improved, which is preferable. The pressing force acting between the drive belt 4 and the boarding belt 3 also depends on the self-weight of the boarding belt 3, particularly the self-weight of the boarding belt 3 in the range in which the passenger is riding, and the tension acting on the boarding belt 3 itself. In particular, in the folded portion of the belt 3, the pressing force acting between the driving belt and the boarding belt largely depends on the tension acting on the entire traveling belt 3. Therefore, even if the passenger does not ride on the boarding belt 3, the driving belt 4 can surely transmit the driving force to the boarding belt 3, and it is preferable to provide a means for imparting the tension of the boarding belt 3. As the tension applying means, -16-(13) 1276599 I can be used in a mechanism in which a conventional belt type passenger conveyor is provided in a driving device of a walking belt. However, the tension applied to the boarding belt 3 by the tension applying means can be greatly reduced compared to the conventional belt type passenger conveyor belt. Therefore, it is applied to the boarding; the negative and the load of the belt 3 are only slightly. . The belt type passenger conveyor 1 is as shown in Fig. 1, and the support roller 2 3 supporting the guide belt 3 is located in a section where the guide rail 20 and the support plate 21 are interrupted. The support roller 23 can also be replaced with a rail of a suitable shape. φ In addition, in the main frame of the range where the passenger does not ride, at least the section where the belt 3 is flexed is provided with a guide roller or a pulley. Again. When the tension applying means such as the conventional belt driving device is installed on the boarding belt, a tensioner drum that applies tension is provided in the vicinity of the section where the belt is flexed. According to this lean form, the following excellent effects can be obtained. In the belt used for the passenger conveyor, the mechanical strength that can withstand high tension and the touch and appearance of the passenger when riding are required. φ In the state where the conventional belt drive device is used, the above requirements cannot be achieved at the same time. On the other hand, according to the belt type passenger conveyor 1 of the present embodiment, the drive belt 4 can maintain a high mechanical strength, and the mechanical strength of the boarding belt 3 in the circulation direction can be low. Motor 1 0, 1. The power of 8 is passed. The drive belt 4 is reached, with which the drive belt 4 is cyclically moved. The belt 3 is engaged with the drive belt 4, and only circulates integrally with the drive belt 4. In other words, the boarding belt 3 is mechanically inferior because it hardly receives the load in the circulation direction. -17- (14) 1276599 Therefore, in the belt type passenger conveyor 1, it is possible to design a boarding belt 3 that emphasizes texture. Further, by maintaining the cross-sectional shape of the boarding belt 3 by providing the core material 3c as shown in FIG. 2, it is possible to easily reach the belt without sacrificing the texture, and the driving belt 4 is a flat belt which can be used in a simple cross-sectional shape. Therefore, it is easy to form. Since the drive belt 4 can substantially ensure the strength in the circulation direction, the strength can be easily secured. Further, the shape of the φ roller 8 of the winding drive belt 4 may be simple. Since the overall shape of the boarding belt 3 can be made the same as the conventional shape, the passenger does not feel uncomfortable, and the safety can be ensured in the same manner as in the related art. Further, since the boarding belt 3 and the driving belt 4 do not slide relative to each other, the boarding belt 3 does not idle during an emergency stop, and the same safety as in the past can be ensured. Further, since the driving force is transmitted to the boarding belt 3 at a plurality of places by the driving belts 4a, 4b, 4c, it is possible to prevent an excessive load from being applied to any one of the driving φ belts 4a, 4b, 4c. In other words, even if the total length of the boarding belt 3 becomes long, a sufficient driving force can be supplied by increasing the number of driving belts 4. . Furthermore, the structure of the drive belt 4 and the drive mechanism 5 constructed in accordance with the present invention can also be transported in one passenger. Set one machine. In the embodiment, the first drive mechanism 5a and the second drive mechanism 5b have different structures, but are not limited thereto. It is also possible that all of the plurality of drive mechanisms 5 have the same configuration. [Second Embodiment] -18- (15) (15) 1276599 A belt type passenger conveyor 3 1 according to a second embodiment will be described with reference to Figs. 5 and 6 . The passenger conveyor 31 has a "intermediate acceleration type" in which the speed of the intermediate belt 3 1 B is higher than the speed of the end portions 31A and 31C of the riding port or the descending port. In the second embodiment, the components having the same functions as those of the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated. As shown in FIG. 5, the passenger conveyor 31 includes a boarding belt 33, a first driving belt 34a, a second driving belt 34b, and a third driving belt 34c. The riding belt 33 is a belt for the passenger to directly ride, and is circulated along a circulation path provided in the main frame 32. The first drive belt 34a and the third drive belt 3 4 c are disposed adjacent to the end portions 3 1 A, 3 1C of the passenger conveyor that are the riding port or the descending port side to drive the boarding belt 33. The second drive belt 34b is disposed in the intermediate portion 3 1 B of the passenger conveyor 31 to drive the boarding belt 3 3 〇 the first drive belt 34a and the third drive belt 34c are used as the shorter end portions 31A, 3 1C The segment ' extends along the carrying direction. On the side of the boarding pass, the drive belt and the boarding belt 3 3 are folded back and guided to the upper side of the drum 8. On the lower side, the drive belt and the boarding belt 3 3 are folded back and guided to the lower side of the drum 8. Almost all sections of the passenger conveyor 31 are occupied by the second drive belt 3 4b. Further, the structure of the second drive belt/belt 34b may be formed to be divided into a plurality of pieces to share the driving force for the boarding belt 3 3 . Each of the drive belts 34a, 34b, and 34c is a drive mechanism 35 having substantially the same structure as the first drive mechanism 5a described above with reference to Figs. 1 and 2 (the first drive mechanism 3 5 a, the second drive) Mechanism 3 5 b, 3rd drive -19- (16) (16) 1276599 structure 35c) to drive. At this time, the first drive belt 34a circulates at the speed VI, and the second drive belt 34b circulates at a speed V2 greater than the speed VI. In order to set the speed between the first drive belt 34a and the second drive belt 34b. The difference is set, and the diameter of the roller sprocket or the timing pulley provided in each of the drive belts 34a and 34b is appropriately set. Further, the second drive mechanism 35b shown in Fig. 5 is formed such that the positional relationship between the second drive mechanism 5b and the pressure roller 13 and the drive roller 12 as shown in Fig. 3 is such that the clamped travel belt 33 is vertically opposed. The drive roller 12 of the second drive mechanism 35b shown in Fig. 5 has a tooth groove on the outer circumference. As shown in Fig. 6, the outer peripheral surface of the second drive belt 34b is formed with a tooth groove 34d to engage with the tooth groove of the drive roller 12. The riding belt 33 is a member that elastically extends at least in the circulation direction, W ((V2/V1)-1) X 100%. In the passenger conveyor 3 1, the first drive belt 34a, the second drive belt 34b, and the third drive belt 34c are driven at speeds VI, V2, and VI, respectively. As a result, the boarding belt 33 extends, so that it moves at a speed v 1 near the end portions 3 1 A and 3 1 C and at a speed V2 at the intermediate portion 3 1B. Thus, the reason why the stretchable member can be used for the boarding belt 3 3 is that the effect of the first embodiment is also described, and the boarding belt 3 3 does not require a large strength in the circulation direction. As shown in Fig. 6, the boarding belt 33 used in the passenger conveyor 31 is also formed into a rectangular flat belt having a thin cross section similarly to the user of the conventional belt type passenger conveyor. Both side edges of the belt 3 3 in the width direction are supported by the guide rollers 36. The belt 3 3 is the same as that of the first embodiment. -20- (17) (17) 1276599 The ground has a plurality of core materials 3 3 a arranged at equal intervals in the circulation direction of the boarding belt 3 3 . The plurality of core materials 33a are coupled to each other by a telescopic sling 33b. The extension sling 33b is an extension restricting member for extending the extension required to extend the circulation direction of the belt 33 and preventing the belt 3 3 from being excessively stretched. The core material 3 3 a and the telescopic sling 33 b are embedded in the coating layer 33c composed of the elastic material constituting the boarding belt 33. In the second embodiment, a difference occurs between the speed V Γ of the first drive belt 34 4 a and the speed V 2 of the second drive belt 34 bb. Therefore, it is necessary to prevent slippage between the take-up belt 3 3 and the drive belts 3 4 a, 3 4 b, 3 4 c. Therefore, it is required to have a higher driving efficiency between the riding belt 3 3 and the driving belts 3 4 a, 3 4 b, 3 4 c, that is, the riding belt 3 3 and the driving belts 3 4 a, 34b, 34c. The exact engagement between the two. Therefore, the tooth groove 3 3d is formed on the inner circumferential surface of the boarding belt 33, and the tooth groove 34d is formed on the outer peripheral surface of the belts 34a, 34b, and 34c. At this time, the slots 3 3 d and the slots 3 4 d respectively form complementary shapes. The shape of these grooves 3 3 d, 3 4 d is in addition to the belt 3 3, driving the skin. The surface of the belts 3 4 a, 3 4b, and 34c has a concave-convex shape as shown in Fig. 6, and the crucible can be formed into a triangular wave-shaped shape of a mountain and a valley, and a tooth-like shape of a gear. As shown in Fig. 6, the core material 3 3 a has a core protruding portion 3 3 e that protrudes toward the inner peripheral surface side of the boarding belt 33. The core protruding portion 3 3 e is engaged with the tooth groove 34d of the driving belts 34a, 34b, 34c. Thereby, since the core material 3 3a can be stably engaged with the ball input mechanism 34, the transmission efficiency of the driving force can be improved-21 - (18) 1276599 Further, the shape of the front end of the core protruding portion 3 3 e is The shape of the groove shape of the tooth groove 34d of the drive belts 34a, 34b, and 34c is formed to be 'other than the shape of the front end of the core protrusion 3 3 e. The core protrusion 33e is provided to be engaged with the drive belt 34a. , Rectangular grooves of the grooves 34d of 34b, 34c. Further, the meshing structure of the boarding belt 3 3 and the driving belts 34 a and 3 4 b as shown in Fig. 6 can of course be applied to the first embodiment. In order to increase the strength and rigidity in the circulation direction, the steel strip 3 4 e is embedded in φ inside the drive belts 34a, 34b, 34c. This steel strip 3. 4e may be the reinforcing sling 4h shown in the first embodiment. Further, as compared with the drive belt 4 shown in the drawing, the drive belts 34a, 34b, and 34c are provided with the surface shape of the tooth groove 34d and the point of the steel strip 34e as a reinforcing material, as shown in FIG. It is different from the drive belt 4. When the first drive belt 34a is moved to the second drive belt 34b, the ride belt 33 abruptly extends, and when the second drive belt 34b moves to the third drive belt 34c, it contracts rapidly. Therefore, in order to prevent deterioration of the boarding φ belt 33, it is preferable to prevent a local load from being applied to the boarding belt 33. An example of this would be shown in Figure 6. The speed changing means 37 is provided between the first drive belt 34a and the second drive belt 34b. The speed changing means 37 is provided to gradually change the speed of the ride belt 33 from VI to V2. Hereinafter, the speed changing means 37 will be described in more detail with reference to Fig. 6 . As shown in Fig. 6, the 'speed changing means 37 has a plurality of drum sets 38. The drum set 38 is a drive roller 38 8a, 3 8a4 having a wide drum having substantially the same width as the drive belt; and a transfer drum 38b1, 38b2, 38b3, 38b4, 38b5, 38b6 having a narrow width narrower than the rollers. , 38b7 -22- (19) (19) 1276599 constitutes. The grooves 3 8 c 3 and 3 8 c 4 which are engageable with the slots 33d formed on the inner circumferential surface of the boarding belt 33 are provided on the outer circumferential surfaces of the driving rollers 3 8 a 3 and 3 8 a 4 . The transfer roller 3 8 b 1 is disposed coaxially with the folding roller '4 f. The transfer roller 3 8 b 2 is disposed coaxially with the folding roller 4 g. The transfer roller 3 8 b3 is disposed coaxially with the drive roller 3 8 a 3 . The transfer roller 3 8 b 4 is disposed coaxially with the drive roller 3 8 a4. The conveying rollers 38b5 are in contact with the conveying rollers 3 81^1, 38133, respectively. The transfer rollers 38匕6 are in contact with the transfer rollers 38133, 38b4, respectively. The conveying rollers 38b7 are in contact with the conveying rollers 38b4, 38b2, respectively. In order to reliably convey the power transmission of the rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, 38b7, the conveying rollers 38b5, 38b6, 38b7 are pressed against the conveying rollers 38b1, 38b2 by the springs 38e5, 38e6, 38e7. 3 8b3 - 3 8b4 Here, the rotational speeds of the drive rollers 38a3, 38a4 are set such that the circulation speed of the first drive belt 34a gradually increases to form the circulation speed of the second drive belt 34b. Specifically, the ratio of the diameters of the transfer rollers 38b1, 38b2, 38b3, and 38b4 to the folding rollers 4f and 4g and the drive rollers 38a3 and 38a is set to be from the first drive belt 34a side to the second drive belt 34b. On the side, it becomes smaller in stages. Further, the moving speed is decelerated by the second drive belt 34b toward the third drive belt 3 4c. Therefore, the rotational peripheral speed of the drive roller of the drum set 38 provided as the speed changing means 37 between the second drive belt 34b and the third drive belt 34c is set to be rotated by the second drive belt 3 4 b. The speed gradually becomes slower until the rotation speed of the third drive belt 3 4x. That is, the ratio of the diameter of the transfer roller, which is -23-(20) (20)1276599 folding roller and drive roller as a reference, is set to gradually increase. The outer peripheral surfaces of the conveying rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, and 3 8b 7 may be smoothed if the driving force is transmitted to each other to the extent that frictional force is generated. Specifically, it is preferable that the outer peripheral surface of each of the conveying rollers is formed of a soft material having a high degree of adhesion. Further, a tooth groove may be provided on the outer circumferential surface of the transmission roller, and the driving force may be transmitted by the mesh grooves being meshed between the transmission rollers 38b1, 38b2, 38b3, 38b4, 38b5, 38b6, and 38b7. Since the speed changing means 37 has the above configuration, the peripheral speed of the drive rollers 38a3, 38 a4 becomes larger as it approaches the second drive belt 3 4b side. In the drive roller 38a3 close to the side of the first drive belt 34a, Weekly speed system. The diameter of each of the communication rollers is set such that the circulation speed of the first drive belt 34a is slightly larger than the circulation speed of the drive roller 38a4 closer to the second drive belt 34b side than the second drive belt 34b. In addition, the case where the drive roller is two or more is the same. Further, when the peripheral speed of the drive roller is changed stepwise between the first drive belt 34a and the second drive belt 34b, the drive roller and the transfer roller between the folding rollers 4f and 4g may have the same configuration as described above. By the first drive belt 34a. The speed of the upper belt 3 3 which is separated from the second drive belt 34b is gradually increased from V 1 to V 2 . As a result, the boarding belt 33 is interposed between the first drive belt 34a and the second drive belt 34b in a stepwise manner. Therefore, it is possible to prevent a large load from being locally applied to the riding belt 33. -24- (21) (21) 1276599 The boarding belt 33 that has reached the second drive belt 34b extends ((V2/V1) -1) X 1 〇〇% when it is located on the first drive belt 34a. When this state is maintained, it moves in the same direction as the second drive belt 34b. Therefore, in order to positively engage the tooth groove 34d formed in the boarding belt 33, the tooth groove 34d formed in the first drive belt 34a, and the tooth groove 34d2 formed in the second drive belt 34b, the distance between the slots 34d2 is P2. It is set to be V2/V1 times the distance P1 between the slots 34d1. Further, the pitch of the slots 28cl, 38c2 formed in the drive rollers 38a3, 38a4 is set to be larger than the distance P1 between the slots 34d1 and smaller than the pitch P2 between the slots 34d2. The pitch of the tooth grooves 3 8c4 of the drive roller 3 8 a4 close to the second drive belt 3 4 b side is set to be larger than the distance between the teeth 38c3 of the drive roller 38a3 on the side closer to the first drive belt 34a. As described above, when the speed of the boarding belt 3 3 is changed, it is preferable to notify the passenger of the change. Therefore, the first drive belt 34a and the second drive belt 34b are colored in different hues or colors, respectively. In this case, the passenger can confirm the color of the drive belts 34a, 34b and the drive rollers 38a3, 38a4, and the boarding belt 3 3, in particular, the cover layer 3 3 c is formed at least in part by a light transmissive material. As the light transmissive material, a transparent or translucent member may be used, and a plurality of holes may be provided on the net. As an example of coloring, the color of the second drive belt 34b is colored to reflect a high-speed color, and the color of the first drive belt 34a is colored to reflect a color at a slower speed. For example, the second drive belt 34b is colored red, and the first drive belt 34a is colored yellow. Further, when the colors of the driving rollers 38a3 and 38a4 which are the intermediate speeds are made of orange and the intermediate color of -25-(22) (22) 1276599 yellow, the moving speed can be visually changed gradually. At this time, the color of the driving rollers 3 8 a3, 3 8 a4 is closer to the first driving belt 34a, as. The closer to the yellow orange, the closer to the second drive belt 34b, the closer to the red orange is preferred. Furthermore, the colors of the driving belts 3 4 a, 3 4 b, 3 4 c and the driving rollers 3 8 a3 and 3 8 a4 may be colored (colors with colors) other than yellow, orange and red, and Limited to colored, it can also be achromatic without different tone. by. The driving belt 34a is changed in color by the driving rollers 38a3, 38a4 to the second driving belt 34b, and may be a gradation (g r a d a t i ο η ) according to a change in brightness or a change in chroma. Fig. 6 shows a portion in which the first drive belt 34a which is the one end portion 31 of the take-up port or the lowering port of the belt type passenger conveyor 31 is converted into the second drive belt 34b. The third drive belt 34c having the same structure as the first drive belt 34a and the third drive mechanism 35c having the same structure as the first drive mechanism 35a are disposed at the end portion 3 1 C opposite to the belt type passenger conveyor 31. . Further, the speed changing means 37 having the same structure as the speed changing means 37 is disposed between the third drive mechanism 35c and the second drive mechanism 35b.

The passenger conveyor of the third embodiment differs from the passenger conveyor 3 1 described in the second embodiment in the configuration of the = drive belts 34a, 34b, 34c and the speed changing means 37. Therefore, the differences from the previous embodiment will be described, and the other portions will be referred to the first and second embodiments, and the description thereof will be omitted. Further, in Fig. 7, in order to create the visible speed changing means 3, the driving belt and the riding belt 33 contacting the upper surface of the speed changing means 37 are shown by a two-dotted broken line. As shown in Fig. 7, the passenger conveyor is in the first embodiment. Between the region where the drive belt 62 is in contact with the boarding belt 33 and the region where the second drive belt 63 and the boarding belt 33 are in contact with each other, there is provided a group of intermediate drive belts 64 as a speed changing means 37. The intermediate drive belt 64 is in contact with the boarding belt 33 to impart a driving force. Further, the intermediate drive belt 64 may be arranged in plural in the conveyance direction between the first drive belt 62 and the second drive belt 63. The first drive belt 62, the second drive belt 63, and the intermediate drive belt 64 are divided into a plurality of division belts 62a, 62b, 62c, 62d, 62e, ..., 63a, 63b, 63c, respectively, in the width direction. 63d, 63e···; 64a, 64b, 64c, 64d, 6 4 e constituting each of the division belts 62a, 62b, 62c, 62d, 6 2 e ···; 63a, 63b' 63c, 63d, 63e· 64a, 64b, »27- (24) (24) 1276599 64c, 64d, 64e~ are arranged in parallel along the transport direction, and the positions of the respective folded portions are mutually along the transport direction.

The zigzag shape of the arrangement of the folded portions of 64d, 64e, .... Further, the shape of the folded portion of the drive belt adjacent to each other is arranged in a state of being meshed with each other in the conveyance direction. That is, the folded portion of the dividing belts 62a, 62b, 62c, 62d, 62e, ... of the first driving belt 62 and the dividing belts of the intermediate driving belt 64 are 6 4 a, 6 4 b, 6 4 c, 64 d, 6 The folding portions of 4 e... are engaged with each other. Further, the folded portions of the divided belts 6 4 a, 6 4 b, 6 4 c, 6 4 d, 64e of the intermediate drive belt 6 4 and the divided belts 63a, 63b, 63c, 63d, 63e of the second drive belt 63 are included. The folding portions are engaged with each other. Each of the divided belts is supported by the folding drum at the position of each of the folded portions. The folding rollers 69a, 69b, 70a, 70b, 70c, and 70d are respectively disposed in a direction orthogonal to the conveying direction of the passenger conveyor and arranged in a direction parallel to each other. In Fig. 7, in order to see the folding rollers of -28-(25) 1276599 disposed on the inner side of the drive belt, the plurality of split strips on the deep side are removed and shown. As shown in Fig. 7, the odd-numbered divided strips 62a, 62c, 62e, ... are counted by the end of the first drive belt 62 and hung on the folding drum 7A. The split strips 6 2 b, 6 2 d..., which are even numbers from the end, are hung on the folding drum 6 9 a. The odd-numbered dividing belts 63a, 63c, 63e, ... are counted from the end portions of the second driving belt 63, and are hung on the folding drum 6 9 b. The split strips 6 3 b, 6 3 d... which are even numbers from the end are attached to the folding drum 7 〇 d. Further, the divided bands 64a, 64c, 64e, ... which are odd-numbered in the width direction of the intermediate drive belt 64 are hooked on the folding rollers 6 9 a, 70c. The split strips 6 4 b, 6 4 d... which are even numbers from the end are hung on the folding drum, 69b, and are arranged such that the folded portions are engaged with each other, and the riding belt 33 is attached from the riding port to the lowering opening. The section on which the passenger is boarding must be separated from the first drive belt 6 2 by 6 2 a, 6 2 b, 62 c, 6 2 d, 6 2 e · · ·, the split belt 64a, 64b, 64c of the intermediate drive belt 64 One of the second drive belts 63 of the second drive belt 63 is in contact with 64d, 6 4 e.... Therefore, the riding belt 33 can obtain a reliable driving force from the driving belts 62, 63, 64. Further, the arrangement having such overlapping portions is not limited to the "intermediate acceleration type". It can also be applied to the arrangement of the drive belts 4a, 4b, 4c of the passenger conveyor 1 according to the first embodiment. The speed of the intermediate drive belt 64 is set to be larger than the speed VI of the first drive belt 62 and smaller than the speed V2 of the second drive belt 63. The driving force for circulating the intermediate drive belt 64 is obtained by the first drive belt 62 or the second drive belt 63. -29- (26) (26) 1276599 The driving force is transmitted to the first drive belt 6 2, the second drive by the drive rollers 65a, 65b, 65c; the transmission pulleys 66a, 66b1, 66b2; and the timing belts 67a, 67. Belt 6 3, intermediate drive belt 6 4. The drive roller 65 5 a is in contact with the first drive belt 62. The drive roller 65b is in contact with the intermediate drive belt 64. The drive roller 65c is in contact with the second drive belt 63. The transmission pulley 66a is mounted coaxially with the drive roller 65a. The transmission pulleys 6 6b 1 and 66b2 are mounted coaxially with the drive roller 65b. The timing belt 67a is attached to the conveying pulleys 66a and 66bl. The timing belt 67b is hung on the conveyance of the pulleys 6 6b 1 and 6 6c. The diameters of the transmission pulleys 66a, 66b 1, 66b2, and 66c are set such that the speeds of driving the stagnations 62, 63, and 64 are changed stepwise in the order of the first drive belt 62, the intermediate drive belt 64, and the second drive belt 63. fast. Further, it is preferable that the intermediate drive belt 64 is provided with a complex array. In this case, the circulation speed of each of the intermediate drive belts 64 is set to be larger as it approaches the second drive belt 63 side. Thereby, the speed of the boarding belt 33 which is separated by the first drive belt 62 and directed toward the second drive belt 63 can be increased from VI to V2 in a plurality of stages. In other words, the speed of the second drive belt 63 can be smoothly changed. As shown in Fig. 7, the first drive belt 62 has a pitch 71 having a pitch P on the outer circumference, and the intermediate drive belt 64 has a pitch on the outer circumference: P2. The tooth groove 72 and the second drive belt 63 are serrations 73 having a pitch P3 on the outer circumference. The pitches P1, P2, and P3 are in the relationship of PI < P2 < P3. The ratio of the diameters of the transmission pulleys 66a, 66b1 is set to the ratio of the pitches P1, P2, and the ratio of the diameters of the transmission pulleys 66b2, 66c is set to the ratio of the pitches P2, P3. -30- (27) (27) 1276599 In addition, the belt 3 3 is gradually extended as the speed increases. In other words, when the moving speed of the boarding belt is changed from VI to V2, the second driving belt 63 does not extend sharply at a short distance and extends little by little. Therefore, it is possible to prevent a large load from being applied to the part, and thus the durability of the second drive belt 633 can be improved. Further, as shown in Fig. 7, the transmission pulleys 6 6 a and 6 6 c are attached to the shaft via the couplings 6 8 a and 6 8 c, respectively. By having the coupler 6 8 a, the split belts 62a, 62b, 62c, 62d, 62e, ..., of the first drive belt 62 are directed toward the intermediate drive belt 64, the split belts 6 4 a, 64b, 64 c, 64d, 64e···, the position of the tooth groove 7 1 of the first drive belt 62 and the tooth groove 72 of the intermediate drive belt 64 which overlap each other on the travel line L1 which is moved by the engagement portion between the belt 33 and the drive belts 62 and 64, Consistent. Similarly, by having the coupler 68c, the split belts 6 4 b, 6 4 d... of the intermediate drive belt 6 4 are directed toward the split belts 63 a, 63 c, 6 3 e... of the second drive belt 6 3 The groove 33 of the intermediate drive belt 64 and the groove 73 of the second drive belt 63 are aligned with each other by the movement line L2 of the belt 3 3 and the engagement portions of the drive belts 6 4 and 6 3 . Further, the folding rollers 69a and 69b provided on the transition lines L1 and L2 are provided with the dividing belts having different speeds. Therefore, the folding rollers 69a, 69b correspond to the dividing belt and are divided in the width direction. The respective folding rollers 69a and the folding rollers 69b are supported coaxially with each other and rotated individually. Further, the folding rollers 69a and 69b disposed at intervals may be fixed to the rotating shaft, and the other folding rollers 69a and 69b may be rotatably attached to the rotating shaft. The folding rollers 70a, 70b, 70c, and 70d disposed outside the positions of the transition lines L1 and L2 are one of the products in the width direction. -31 - (28) (28) 1276599 'The distance s 1 around the circulation path of the folding rollers 70a, 70b, 70c, 70d and the distance S around the circulation path of the folding rollers 6 9 a, 6 9 b as shown in Fig. 8 The distance difference between 2 is set to be an integral multiple of PI, P2, and P3 between the slots 71, 72, and 73 of the split tape wound around the bottom. Thereby, the positions of the slots of the adjacent split belts formed as one drive belt can be matched. As described above, by the drive belt constituting the passenger conveyor, as shown in Fig. 7, the moving speed of the boarding belt 33 is gradually increased from VI to V2. Further, in the third embodiment, the speed changing means 3 7 for increasing the speed has been described. However, since the speed changing means for deceleration is only the reverse configuration of the speed changing means for increasing the speed, the description thereof will be omitted. Further, the intermediate drive belt 6 4 ' of the third embodiment may be omitted by the first drive belt 62 and the second drive belt 6 3 in a plurality of drive belts. In this case, it is arranged in a zigzag shape of the folded portion formed in the divided belts 6 2 a, 6 2 b, 6 2 c, 6 2 d, and 6 2 e of the first drive belt 62, and is formed in the second drive. The zigzag shapes of the folded portions of the divided belts 63a, 63b, 63c, 6 3 d, 6 3 e... of the belt 63 are engaged with each other. Further, the circulation speed of the second drive belt 63 can also be made faster than the circulation speed of the first drive belt 62. [Effect of the Invention] According to the present invention, it is possible to suppress a large load from being locally applied to a belt type passenger conveyor of a constant speed type. Therefore, in the passenger conveyor, the abrasion or fatigue of the riding belt can be alleviated. In addition, this passenger conveyor can provide stable operation even when the -32- (29) (29) 1276599 has a long transport distance. Further, according to the present invention, even in the case of the intermediate acceleration type passenger conveyor which increases the conveyance speed from the boarding pass to the lowering port, it is possible to form a traveling belt for the passenger to ride with a continuous belt. Therefore, since the conveyance speed is continuously changed, the feeling of uneasiness of the passenger accompanying the speed change can be alleviated. Moreover, since the riding belt is continuous, it is possible to prevent foreign matter such as pebbles from being caught in the driving system of the passenger conveyor. In other words, it is possible to provide an intermediate-accelerated belt type passenger conveyor that can ensure the safety of passengers to operate. [Industrial Applicability] The belt type passenger conveyor of the present invention can also be utilized as a cargo conveyor in the field of logistics. .
