中’為了使袋體與内容物之搬送速度正確地同步，較佳為 應用隨著正時滑輪之旋轉而行進之正時皮帶作為吸引輸送 帶之皮帶。 圖1 3係表示以支承構件丨〇 7支承於寬度方向兩側之緣 部101形成有齒103之正時皮帶105的構造（參照專利文獻 2)。從將吸引輸送帶小型化之觀點，正時皮帶i 〇5係要求較 /專又’支承構件1 〇7之支承面1 〇9係承抵物品之荷重， 以使正時皮帶105不會因載置於正時皮帶丨〇5之物品的荷 重而變曲。 然而’於支承構件丨07確保支承面丨〇9之部分，除了 會限制用以將負壓導引至正時皮帶i 〇5之通氣孔i丨丨之槽 11 3的寬度以外，亦會限制通氣孔丨丨丨之配置與廣度。此係 不利於使通氣孔1丨i吸引物品之吸引力增大。又由於將 201113212 因此 負壓分配於複數個# 113之分歧路115係不可或缺 會妨礙吸引輸送帶之小型化。 、

又，本發明，其特徵在於’具備：正時"，係通氣 孔貫通於帶體之寬度方向兩側之緣部之間且在較該緣部靠 寬度方向之内方設置有排列於該長邊方向的複數個齒；底 面材，係將該正時皮帶之齒滑動自如地支承於該長邊方向 且形成有將負壓導引至該通氣孔的風路；以及2條氣密概 墊，係延伸於長邊方向且為該帶體兩側之緣部所分別滑動 接觸。 ^又，本發明，其特徵在於：該底面材具有以底面承抵 。亥正時皮帶之齒的導引槽；該風路係於該導引槽之底面開 放，該2條氣密襯墊係彼此隔著該齒所通過之間隔配置於 該導引槽之内側。 4 201113212 又，本發明，其特徵在於，具備：吸引輸送帶，係使 通氣孔貫通於帶體之寬度方向兩側之緣部之間且在較該緣 部靠寬度方向之内方設置有排列於該長邊方向之複數個齒 的正時皮帶行進於水平方向，並藉由導引至該通氣孔之負 壓吸引以該正時皮帶承抵之袋體；以及插入裝置，係使推 件往被該吸引輸送帶吸引之該袋體前進的方向及從該袋體 後退的方向來回運動，方兮故* 動在該推件剛進至該袋體之過程中將 物品推入該袋體。 :’本發明’其特徵在於，具備：底面材，係將該正 :=之齒支承成可滑動自如且形成有將負壓導引至該正 時皮帶之通氣孔的風路；以及2條氣密概塾，係延伸於該 =S皮帶之長邊方向且為該正時皮帶之帶體兩側之緣部所 为別滑動接觸。 ^ =本發明，其特徵在於’具備：膜料供應手段，係 度方向之尺寸受規定之膜料的途中，將膜料形成 马在寬度方向對折重疊的 立的形狀後予以送出；以及製袋裝 料之長軎延伸於°亥膜料之寬度方向的熱切刀，按壓於該膜 料彼此=向的途中，以該熱切刀之熱使該對折重疊之膜 成且=接’且將該膜料在長邊方向之途中載斷，藉此形 成具有開口部之袋體。 較帶體之綠：正時皮帶及吸引輸送帶之氣密構造，由於在 較帶體之緣部靠寬度方 之緣部發揮以下功置有齒，因此可使帶體 旋轉而行進於其長h 使正時皮帶隨著正時滑輪之 再長邊方向瞎， f帶體兩側之緣部分別滑動接 201113212 觸於2條氣密概塾。因此，7 ^ u u此可抑制從支承齒之底面材的風 路導引至正時皮帶之通氣孔的負@，從帶體兩側之緣部與 底面材之間茂漏，以使通氣孔吸引載置於帶體之物品的吸 引力增大。 又本發明之正日寺皮帶之齒，由於亦可發揮補強帶體 之緣部内方之部位的功能，目此風路之寬度即使是齒之齒 寬之半以上的大小，正時皮帶亦不會因載置於帶體之物 0口的荷重而谷易地彎曲至寬度方向。因此，該吸引輸送帶 之氣密構造有利於分別#大通氣孔及風&以增大上述吸引 力。 再者，根據本發明之正時皮帶及吸引輸送帶之氣密構 ^藉由從風路導引至正時皮帶之通氣孔之負壓的作用， 帶體與導引槽之内側的區域，其氣壓係較大氣壓低。由於 基於此等區域與大氣之壓力差，帶體兩側之緣部即被按壓 於2條氣密襯墊，因此該正時皮帶及吸引輸送帶之氣密構 造即可顯著地達成上述效果。 根據本發明之裝袋裝置’藉由將推件來回運動之速度 設定成較高，即可容易地增加每既定時間單位可插入於袋 體之物品的數量。又，由於吸引輸送帶可抑制從吸引手段 導引至皮帶之通氣孔的負壓從帶體兩側之緣部與底面材之 間沒漏’因此具有無需使吸引手段之輸出不必要地增大的 優點。此外，該裝袋裝置係可達成與上述正時皮帶及吸引 輸送帶之氣密構造相同之效果。 6 201113212 【實施方式】 針對本發明之實施形態之正時皮帶、吸引輸送帶之氣 密構造、以及裝袋裝置，根據圖式加以說明。 [實施例1] 如圖1所示，正時皮帶i係在將帶體3寬度方向兩側 之緣部5之間分成兩部分的位置貫穿有通氣孔7,且將以等 間距排列於…之長邊方向的複數個齒9設置於帶體3 之下面。全部之齒9係配置於較帶體3兩側之緣部5靠寬 度方向之内方。帶冑3之緣部5係將其下面形成為平滑之 滑動面。作為帶體3,較佳為應用將能耐受長邊方向之張力 的心線穿通於柔軟性優異之氯平橡膠者。 [實施例2] 如圖2、3所示’吸引輸送帶之氣密構造"，係具備: 正時皮帶1 ;底面# 15 ’係形成有將負壓導引至通氣孔7 的風路13 ;以及2條氣密襯墊17，係帶體3兩側之緣部$ 的下面分別滑動接觸。底面材15係以延伸於長邊方向之導 引槽19的底面承抵正時皮帶i之齒9。導引槽以寬度係 設定成較帶體3之全寬稍寬’導引槽19之深度係設定成盥 將齒9之齒高加上帶體3之厚度後的高度大致相等。風路 13係開放於導引槽19底面之長孔或槽形部，透過導管23 連接於吸引手段。此處 所謂吸引手段只要是如鼓風機等 之吸引口般吸引空氣者即可。 上述吸引手段起動後，大氣即從通氣孔7穿過彼此相 鄰之齒9之間的空隙往風路13流人。例如，將正時皮帶ι 201113212 捲掛於正時滑輪，使正時皮帶丨順著該正時滑輪之旋轉而 行進時’帶體3兩側之緣部5的下面係分別滑動接觸於2 條氣密襯墊1 7。藉此，可抑制大氣穿過帶體3之緣部5與 導引槽1 9之内側面之間。換言之，由於可抑制從風路i 3 導引至通氣孔7之負壓從帶體3兩側之緣部5與底面材15 之間汽漏，因此可使通氣孔7產生能良好地吸引載置於帶 體3之物品的吸引力。 而且’大氣從通氣孔7往風路13流入時，帶體3與導 引槽19底面之内側的區域，其氣壓係較大氣壓低。基於此 等區域與大氣之壓力差，帶體3兩側之緣部5即受到箭頭p 方向之力，而分別按壓於2條氣密襯墊17。藉此，由於帶 體3之緣部5即緊貼於氣密襯墊丨7 ,而可進一步抑制負壓 從帶體3兩側之緣部5與底面材15之間洩漏，因此可使上 述吸引力增大。 又，底面材15之風路13亦可在2條氣密襯墊17之内 側的範圍自由地設定其配置與形狀。χ，由於齒9亦可發 揮補強帶體3之緣部5内方之部位的功能，因此風路13之 寬度即使設定成擴及齒9之齒寬之1/2〜3/4的大小，正時 皮帶1亦不會因載置於帶體3之物品的荷重而容易地彎曲 至寬度方向。因此’吸引輸送帶之氣密構造u有利於分別 擴大通氣孔7之直徑及風路13之寬度以增大上述吸引力。 將普及型之正時皮帶與以上所述之正時皮^ i加以比 較。圖4係表示將齒9之齒寬與帶體3之全寬大致相等之 正時皮帶25插人於導引槽19之例。起動連接於風路13之 8 201113212 吸引手段後，大氣雖從通氣孔7往風路13流入，不過與此 同時，由於大氣係穿過帶體3兩侧之緣部5與導引槽1 9之 内側面的間隙’因此通氣孔7之吸引力即減少該分量。又， 由於愈為了使通氣孔7之吸引力達到所欲之強度而增大上 述吸引手段之輸出’穿過緣部5與導引槽19之内側面之間 隙之大氣的量亦愈增大’因此吸引手段之效率便無可避免 地會降低。 [實施例3] 如圖5所示，吸引輸送帶之氣密構造26，係具備：正 時皮帶1;平板狀之鋁製的底面材15;安裝於底面材15之 上面的2條氣密襯墊17 ;以及分別安裝於該等氣密襯墊17 的2條滑材27。 對在實施例2已述之元件，以下亦使用相同稱呼，並 省略其說明。滑材27係在超過帶體3全寬之大小之物品載 置於正時皮帶丨的情況下’用以將該物品支承成可滑動自 如。氣密襯墊17與滑材27之材質係不鏽鋼。帶體3之全 寬係50mm，通氣孔7之直徑係8mm。複數個通氣孔7之= 距係35mm。氣密襯墊17之厚度係大致等於齒9之齒厚: 從底面材15至滑材27上面之高度係2.2酿。此係大致等 於正時皮帶1之全厚。 [實施例4] 如圖6所示’吸引輸送帶之氣密構造29，係於 之底面材15形成2條凸條部31，以該等凸條部3 導引槽!9,且將由超高分子聚乙烯構成之凹形構件置 201113212 於導引槽19之底面。凹开;j播从1 * 構件33係將底板部37與2條氣 达、襯塾17予以一體化者，1 八f δ亥底板部37係將緊貼於導 引槽19底面並將正時皮帶1的齒9承抵成可滑動自如。由 於凹形構件33之底板部37蚪喜Λ - 7對齒9之摩擦係數較小，因此 相較於以底面材丨5直接支承齒9者，可降低正時皮帶丨行 進時之阻力。符號35係指形成於與底板部37之風路I 致之位置的通風路。 帶體3之全寬係意指正時皮帶1之皮帶寬度[叫，若以 齒9之齒寬為[s]，則單側之緣部5的寬度⑷係―卜 s)/2’較佳為設定於5mn〇_之範圍。或者，若帶 體3之厚度為[t]，則亦可將[ 肝LCT」a又疋於3t$ σ $ i5t之範 圍。 此外’本發明在不超出其要旨之範圍’根據發明 技術領域之通常知識者之知識，亦可實施錢加以改良、 修正或變形之形態。雖圖示了通氣孔7貫穿帶體3之位置 係與彼此相鄰之齒9之間(谷)一致的形態，不過通氣孔7亦 可貫穿齒9。底面材15與氣密襯塾17亦可為一體。帶體3 亦可為無端狀。又’通氣孔7之形狀 '配置、個數、或尺 寸係屬可適宜地變更的事項。 [實施例5] 針對具備正時皮帶1之 吋反妒i之褒k裝置加以說明。_ 7係 不具備膜料供應手段201、製袋襄置203,搬送袋體2〇5之 吸引輸送帶207、將物& 211供應至與袋體2〇5之開口部 2〇9相對向之位置之物品供應手段213、以及插入裝置出 10 201113212 之裝袋裝置200的概略。圖8係表示藉由插入裝置215之 後述動作’物品21 1剛要插入前之袋體205之開口部209 的形狀。 膜料供應手段20 1，如圖7所示，係將捲繞成捲軸狀之 膜料217’形成為在其寬度方向之途中對折重疊的形狀，再 送出至箭頭T之方向。製袋裝置203係以熱切刀219將對 折重疊之膜料217予以加熱，再以熱切刀219之熱來熔斷 此等膜料彼此’藉此形成矩形之袋體2〇5。上述熔斷之部位 22 1則成為對折重疊之膜料2丨7彼此融接之袋體2〇5的側緣 部。 吸引輸送帶207係藉由使支承於已述之底面材丨5之複 數個正時皮帶丨往箭頭τ之方向行進來搬送承抵於正時 皮帶1之袋體205 〇為了使袋體2〇5吸附於正時皮帶1之帶 體3 ’於正時皮帶丨之通氣孔7係從吸引手段導入負壓。又， 如在實施例2所述般’由於藉由帶體3之緣部5緊貼於氣 密襯整1 7 ’可抑制負壓從帶體3兩側之緣部$與底面材i 5 之間洩漏’因此具有無需使將負壓導引至通氣?L 7之吸引 手奴之輸出不必要地增大的優點。 其次’針對插入裝£ 215之構成加以說明。由於在以 下:斤述之驅動源或導引手段可應用公知之技術，因此各別 詳、田說月係予以省略。例如，作為驅動源亦可應用氣缸、 :壓缸、伺服馬達、附減速機之旋轉機、或隨著旋轉機之 :使動作#伸縮的電動紅等。作為導引手段亦可應用使 牛滑動自如地卡合於導軌而成之滑動對偶。 201113212 插入裝置215，如圖9、1 〇所示，係具備：使滑件227 來回運動於水平方向的直線動作手段229、於滑件227透過 導引手段23 1升降自如地連結有立起部233的門形從動保 持具241、將物品211支承於與袋體2〇5相同高度的支承體 243、延伸於水平方向的直線軌道245、以及配置於直線軌 道245之上方的凸輪執道247。 直線動作手段229，係將螺合於進給螺桿249之滾珠螺 帽251連結於滑件227，以驅動源使進給螺桿249旋轉，藉 此使滑件227沿著進給螺桿249移動。進給螺桿249之= 端係旋轉自如地支承於插入裝置215之筐體。推件235，係 以彼此隔離於推件235來回運動之方向的方式，將大致[ 字形之插入爪253及進給爪255安裝於框架237。箭頭f、 R係指推件235與滑件227 一起對袋體2〇5前進或後退之方 向。 從動保持具241之立起部233,係於其内側安裝有可轉 動接觸於直線執道245或凸輪執道247的從動滾輪257。 又，從動保持具241，係於其立起部239固定有推件235之 框架237。支承體243係由山形之輕量型鋼構成的一對導軌 259。導軌259係以其凸緣261來支承物品21丨。導轨259 之凸緣263係用以限制物品21!從一對導執259之内側逸 脫。於一對導軌259之間，亦可設置平滑之底板。 物品供應手段213,雖以於旋轉輪265捲掛有無端皮帶 267者表示於圖10,不過只要是可將物品2ιι從箭頭f之 方向往-對導& 259之内側導人者，並不限制於該圖之形 12 201113212 態。又’於一對導軌259之内側配置有複數個滾輪269。此 係為了使載置於以驅動源行進之無端皮帶267的物品2丨j， 剛從無端皮帶267脫離之後，能以其慣性力滑動。符號271、 273係分別指導轨259之導入部及送出部。 圖10所示之支承板275，係用以支承直線軌道245及 配置於直線軌道245上方之銷277’固定於插入裝置215之 筐體。凸輪軌道247，如圖9所示，係具有將一端279延伸 於箭頭F之方向的傾斜部281、以及將另一端283延伸於箭 頭R之方向的水平部285，以將一端279承抵於直線軌道 245之姿勢，旋轉自如地支承於銷277。傾斜部28丨係只要 疋呈往箭頭R之方向上升傾斜的形狀即可。圖9之符號287 係指用以使銷277插通至凸輪軌道247的插通孔。 以下，說明插入裝置215之動作。圖7所示之製袋裝 置203依序將複數個袋體2〇5予以成形，再藉由袋體搬送 手段207搬送此等袋體205。接著，當一個袋體2〇5之開口 部209到達推件235之插入爪253的正面時，袋體搬送手 段207即停止袋體205之搬送。在該狀態下，#由插入裝 置215之直線動作手段229使滑件227進行來回運動，執 行以下所述動作之第1步驟〜第4步驟。 第1步驟’係在滑件227前進之過程中從動滾輪257 從以虛擬線257·表示於圖9之位置，沿著直線執道245往 箭頭F之方向移動。圖11(昀係表示在本步驟正在執行之期 間，從物品供應手段213供應之物品211，觸碰到推件235 之進給爪2 5 5而停止之時。 13 201113212 進步’從動滾輪257往箭頭ρ之方向移動，從其下 側接觸至凸輪軌道247之傾斜部28卜由於傾斜部28 1係藉 由從動滾輪257推升，因此凸輪軌道247係以銷277為支 點往使一端279上升之方向旋轉。從動滚輪257通過藉此 張開之傾斜部281之一端279與直線執道245的間隙之後， 凸輪軌道247即因自重而往使一端279下降之方向旋轉， 再·人將一端279承抵於直線執道245 ^在滑件227到達前進 之極限時，推件235之進給爪255便到達以實線表示於圖 u(b)之位置。同時，推件235之插入爪253則到達以實線 表示於圖12(a)之位置。 如上述般，在從動滾輪257沿著直線執道245移動之 過転中從動保持具241之高度係藉由直線軌道245定位。 因此，推件235之插入爪253及進給爪255各自的高度， 系與支承於支承體2 4 3的物品2 11 —致。隨著滑件2 2 7前 進’物品211即藉由插入爪253推入袋體2〇5，至物品211 1體插入於袋體205。此處，「一致」意指插入爪253及進 給爪25 5之前端係位於物品2丨丨之稍了側。 第2步驟’係在滑件227後退之過程中從動滾輪257 沿著直線轨道245往箭頭R之方向移動，而到達凸輪轨道 247之傾斜部281的一端279。另一方面，推件235之插入 爪253即從在第i步驟插入於袋體2〇5之物品211脫離， 並自袋體205後退。 第3步驟’係滑件227進一步後退’從動滾輪257即 跨上傾斜部28丨。在此時點，由於從動滾輪257之荷重係向 14 201113212 輪軌道247’因此凸輪執道247係維持將一端 Μ承抵於直線軌道245之姿勢。往箭…方向移動的從 動滾輪257 ’係順著凸輪軌道247之傾斜部281上升之後， 即如者水平部285移動。藉此，由於從動保持& 241與從 動滾輪257起上升之後即以水平移動，因此推件235之 進給爪255係如以虛擬線255,表示於圖"⑻般通過物品 211之上方。 第4步驟，係從動滚輪257從凸輪執道247之水平部 285的另一端283脫離，回歸至以虛擬線257，表示於圖9之 位置。在此時點，推件235之進給爪255係較物品2ιι進 一步後退，而到達以虛擬線255”表示於圖n(b)之位置。 又，由於從動滾輪257係在從水平部285之另一端283脫 離之後，即下降至承抵於直線執道245之高度，因此推件 235亦與從動保持具241 —起下降。 接著’袋體搬送手段207即恢復袋體205之搬送，在 後接於已插入有物品21 1之袋體205之另一袋體2〇5的開 口部209到達推件235之插入爪253的正面時，袋體搬送 手段207即停止袋體205之搬送。插入裝置215便執行第2 次之第1步驟。在該期間，另一物品2丨丨即從物品供應手 段213供應至表示於圖n(a)之位置。 另一方面’從以虛擬線255”表示於圖11(b)之位置前 進之推件235的進給爪255，係將在第1次之第1步驟期間 所供應之物品21 1予以卡止，使此物品2 11前進。藉由執 行第2次之第2步驟〜第4步驟，推件235之進給爪255 15 201113212 即通過在第2次之第1步驟期間所 間所供應之物品211的上方， 同時推件235之插入爪253,如以虎椒綠，r 虛擬線253’表示於圖12(a) 般，通過在第1次之第1步驟期 邓朋間所供應之物品211的上 方，而到達以虛擬線253”表示之位置。 然後，藉由進一步反覆進行第 J罘i步驟〜第4步驟，在 第1次之第1步驟期間所供應之物0 °口 211，如圖12(b)所示 般’便藉由推件235之插入爪253 3J從一對導軌259之間推 出，而插入於圖8所示之袋體2〇5的開口部2〇9。又，由於 每次物品211插人於1個袋體205時，袋體搬送手段2〇7 係反覆進行袋體205之搬送與停止，因此插入裝置215便 可使依序供應自物品供應手段213之複數個物品2n，分別 插入於藉由吸引輸送帶207搬送之複數個袋體2〇5。 插入裝置2 1 5 ’係以將一對可動導件3〇丨設置於一對導 執259與開口部2〇9之間較佳一對可動導件如，係將各 自之突端303言史置成楔形，且將剖面形成為彼此向内之槽 形。再者，插入裝置215，係以具備：將一對可動導件3〇1 移動自如地導引至箭頭F、R之方向的導引手段、以及使一 對可動導件3〇 1進退於此方向的導驅動手段較佳。 此時，預先使可動導件301從圖示之位置後退，以使 可動導件301之突端303從袋體2〇5之開口部2〇9脫離， 在第1步驟物品21 1剛要從一對導軌259之間推出之前， 使對可動導件301前進，使各自之突端3〇3進入開口部 2〇9。藉此，可使開口部2〇9較物品2丨丨之尺寸更大地張開， 而可事先預防要插入於袋體205之物品211被開口部2〇9 16 201113212 卡住等的不良。 又’亦可於吊持在正睥 設置吸附墊3〇7,藉由從二丰方之導管3〇5的下端 塾307的負壓，在斜引手段透過導管305導引至吸附 袋體2〇5之二ΪΓ可動導件301剛要前進之前，吸引 指，以使開口部209往正時皮帶i之上 方張開。又，亦可太 必 方τ在一對可動導件3〇1正從袋體2〇5後退 時，使各自之突端3〇3傾 1貝针至彼此接近之方向，在突端303 進入開口部20Q r主 .、，& ' 使各自之突端303之間隔拉開的方 式，使可動導件301 计 動作。藉此’使張力產生於袋體2〇5 之開口部2〇9,即可預防開口部2⑽之鬆弛。 ，此外’本發明在不超出其要旨之範圍，根據發明所屬 技術領域之通常知識者之知識，亦可實施加以各種改良、 修正或變形之形態。亦可省略圖7所示之膜料供應手段201 與製袋裝置203 ’而將物品211插入於現成之袋體。此時， 亦可將現成之袋體直接供應至吸引輸送帶207之正時皮帶i 亦可省略進給螺桿249與滾珠螺帽25 1，而應用 將β件227接合於活塞桿之驅動源以作為直線動作手段 229 〇 亦可將吸引輸送帶207搬送袋體205之速度予以倍

This is not conducive to increasing the attraction of the vent 1i to attract items. In addition, due to the fact that 201113212, the negative pressure is distributed to a plurality of #113 divergent roads 115 is indispensable, which hinders the miniaturization of the suction conveyor belt. [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei. No. 292-254. [PRIOR ART] The present invention is directed to providing a good attraction and attraction. A timing belt that contributes to the miniaturization of the conveyor belt, a suction conveyor dense structure, and a bagging device. The present invention relates to a timing belt which is disposed between a rim portion of a vent hole passing through both sides of a wide production direction, and is arranged in a longitudinal direction of the belt: a plurality of teeth, characterized in that: The teeth are disposed in the width direction from the edge portion of the belt body. Further, the present invention is characterized in that "there is a timing", and the vent holes are formed between the edge portions on both sides in the width direction of the belt body, and are arranged in the width direction of the edge portion. a plurality of teeth in the longitudinal direction; the bottom material is slidably supported by the teeth of the timing belt in the longitudinal direction and is formed with an air path for guiding the negative pressure to the vent hole; and two airtight systems The pads extend in the longitudinal direction and are in sliding contact with the edges of the two sides of the strip. Further, the present invention is characterized in that the bottom material has a bottom surface. a guiding groove of the tooth of the timing belt; the air path is opened on the bottom surface of the guiding groove, and the two airtight gaskets are disposed inside the guiding groove at intervals between the teeth. In addition, the present invention is characterized in that the suction belt is provided with a vent hole penetrating between the edge portions on both sides in the width direction of the belt body and arranged in the width direction of the edge portion. a timing belt of a plurality of teeth in the longitudinal direction travels in a horizontal direction, and attracts a bag body that is received by the timing belt by a negative pressure guided to the vent hole; and an insertion device that pushes the pusher Moving back and forth to the direction in which the bag is attracted by the suction conveyor belt and moving backwards from the bag body, the article pushes the article into the bag body just as the pusher has just entered the bag body. . The present invention is characterized by comprising: a bottom material, wherein the teeth of the positive:= are slidably formed and a wind path for guiding a negative pressure to the vent hole of the timing belt; and two The airtightness is extended in the longitudinal direction of the belt and is the sliding contact of the edges of both sides of the belt of the timing belt. ^ = The present invention is characterized in that: "the film supply means is provided, and the size of the film is in the middle of the predetermined film material, and the film is formed into a vertical shape in which the horses are folded in the width direction; and the bag is formed; The long slit of the charging material extends in the width direction of the film material, and is pressed against the film material in the middle of the direction of the film, and the film of the folded film is overlapped by the heat of the hot cutting blade and the film is formed The material is loaded in the middle of the longitudinal direction, thereby forming a bag body having an opening. The green color of the belt: the airtight structure of the timing belt and the suction conveyor belt, because the edge of the belt body is at the edge of the width, the following functions are provided, so that the belt body can rotate and travel long. h Make the timing belt 瞎 with the longer side of the timing pulley, and the edges of the sides of the f-belt are respectively slid and connected to 201113212 to touch the two airtight profiles. Therefore, 7 ^ uu can suppress the negative @ from the air path of the bottom material of the supporting tooth to the vent hole of the timing belt, and leak from the edge between the both sides of the belt body and the bottom material to make the vent hole The attraction of the items placed on the belt is increased. Further, since the teeth of the Zhengri Temple belt of the present invention can also function to reinforce the inner portion of the edge portion of the belt body, the width of the air passage is not greater than half the width of the teeth, and the timing belt is not It will be bent to the width direction due to the load placed on the 0-port of the belt. Therefore, the airtight structure of the suction conveyor belt facilitates the respective #large vent holes and wind & to increase the above-mentioned attractive force. Furthermore, according to the present invention, the timing belt and the airtight structure of the suction conveyor belt act by the negative pressure of the vent hole guided from the air passage to the timing belt, the inner side of the belt body and the guide groove, Its air pressure is low and the air pressure is low. Since the edge portions on both sides of the belt are pressed against the two airtight gaskets based on the pressure difference between the regions and the atmosphere, the airtight structure of the timing belt and the suction conveyor belt can remarkably achieve the above effects. The bagging apparatus according to the present invention can easily increase the number of articles that can be inserted into the bag per predetermined time unit by setting the speed at which the pusher moves back and forth to be high. Further, since the suction belt can suppress the negative pressure from the suction means to the vent hole of the belt from leaking between the edge portions of the both sides of the belt and the bottom material, there is no need to unnecessarily increase the output of the suction means. The advantages. Further, the bagging device can achieve the same effect as the airtight structure of the timing belt and the suction conveyor. [Embodiment] The timing belt, the airtight structure for sucking the conveyor belt, and the bagging device according to the embodiment of the present invention will be described with reference to the drawings. [Embodiment 1] As shown in Fig. 1, the timing belt i is inserted into the vent hole 7 at a position where the edge portions 5 on both sides in the width direction of the belt body 3 are divided into two, and will be arranged at equal intervals in ... A plurality of teeth 9 in the longitudinal direction are disposed below the belt body 3. All the teeth 9 are arranged in the width direction of the edge portion 5 on both sides of the belt body 3. The edge portion 5 of the belt 3 has a smooth sliding surface formed on the lower surface thereof. As the belt body 3, it is preferable to apply a core wire which can withstand the tension in the longitudinal direction to the chlorine rubber which is excellent in flexibility. [Embodiment 2] As shown in Figs. 2 and 3, the "airtight structure of the suction conveyor belt" includes: a timing belt 1; a bottom surface #15' is formed with a wind passage for guiding the negative pressure to the vent hole 7. 13; and two airtight gaskets 17, the lower sides of the edge portions of the ligaments 3 are respectively in sliding contact. The bottom material 15 is supported by the teeth 9 of the timing belt i at the bottom surface of the guide groove 19 extending in the longitudinal direction. The guide groove is set to be slightly wider than the full width of the belt body 3 by the width. The depth of the guide groove 19 is set to be substantially equal to the height of the tooth 9 plus the thickness of the belt body 3. The air passage 13 is open to the long hole or the groove portion of the bottom surface of the guide groove 19, and is connected to the suction means through the duct 23. Here, the suction means may be any one that attracts air like a suction port such as a blower. After the above-described attraction means is started, the atmosphere flows from the vent hole 7 through the gap between the teeth 9 adjacent to each other to the air path 13. For example, when the timing belt ι 201113212 is hung on the timing pulley so that the timing belt 行进 travels along the rotation of the timing pulley, the lower sides of the edge portions 5 on both sides of the belt body 3 are respectively slidably contacted with two Airtight gasket 17. Thereby, it is possible to suppress the atmosphere from passing between the edge portion 5 of the belt body 3 and the inner side surface of the guide groove 19. In other words, since the negative pressure from the air passage i 3 to the vent hole 7 can be suppressed from leaking between the edge portion 5 on both sides of the belt body 3 and the bottom surface member 15, the vent hole 7 can be sucked well. The attraction of the item placed in the body 3. Further, when the atmosphere flows from the vent hole 7 to the air passage 13, the region inside the bottom surface of the belt body 3 and the guide groove 19 has a low air pressure and a low air pressure. Based on the pressure difference between the regions and the atmosphere, the edge portions 5 on both sides of the belt body 3 are pressed by the force in the direction of the arrow p, and are pressed against the two airtight gaskets 17, respectively. Thereby, since the edge portion 5 of the belt body 3 is in close contact with the airtight gasket 7 , it is possible to further suppress the leakage of the negative pressure from the edge portion 5 and the bottom surface member 15 on both sides of the belt body 3, thereby making it possible to Increased attraction. Further, the air passage 13 of the bottom member 15 can be freely set in the range of the inner side of the two airtight gaskets 17, and its arrangement and shape can be freely set. In other words, since the teeth 9 can also function to reinforce the inner portion of the edge portion 5 of the belt body 3, the width of the air passage 13 is set to be larger than the tooth width of the teeth 9 by 1/2 to 3/4. The timing belt 1 is also not easily bent to the width direction due to the load of the articles placed on the belt body 3. Therefore, the airtight structure u of the suction conveyor belt is advantageous in expanding the diameter of the vent hole 7 and the width of the air passage 13 to increase the above-mentioned attractive force. The popular timing belt is compared with the timing paper described above. Fig. 4 shows an example in which the timing belt 25 is inserted into the guide groove 19 with the tooth width of the tooth 9 substantially equal to the full width of the belt body 3. After the start of the connection to the air passage 13 201113212, the atmosphere flows from the vent hole 7 to the air passage 13, but at the same time, the atmosphere passes through the edge portion 5 and the guide groove 19 on both sides of the belt body 3. The gap in the inner side of the gap ′ thus the attraction of the vent 7 reduces this component. Further, as the attraction force of the vent hole 7 is increased to the desired intensity, the output of the attraction means is increased as the amount of the atmosphere passing through the gap between the edge portion 5 and the inner side surface of the guide groove 19 is increased. Therefore, the efficiency of the attraction will inevitably decrease. [Embodiment 3] As shown in Fig. 5, the airtight structure 26 for sucking the conveyor belt includes a timing belt 1; a flat aluminum bottom material 15; and two airtight seals attached to the upper surface of the bottom material 15. A gasket 17; and two sliding materials 27 respectively attached to the airtight gaskets 17. For the elements already described in the second embodiment, the same reference numerals are used hereinafter, and the description thereof will be omitted. The sliding material 27 is used to support the article in a slidable condition when the article exceeding the full width of the belt body 3 is placed on the timing belt loop. The material of the airtight gasket 17 and the sliding material 27 is stainless steel. The belt body 3 has a full width of 50 mm and the vent hole 7 has a diameter of 8 mm. The number of vents 7 is 35 mm. The thickness of the airtight gasket 17 is substantially equal to the tooth thickness of the tooth 9: the height from the bottom material 15 to the upper surface of the sliding material 27 is 2.2. This system is roughly equal to the full thickness of the timing belt 1. [Embodiment 4] As shown in Fig. 6, the airtight structure 29 of the suction conveyor belt is formed by the bottom material 15 forming two ridge portions 31, and the ridge portions 3 are guided by the ridges 9 and will be super A concave member made of high molecular weight polyethylene is placed on the bottom surface of the guide groove 19 at 201113212. The groove is opened from the 1* member 33, and the bottom plate portion 37 is integrated with the two gas linings and the linings 17, and the first and second f δ hai floor portions 37 will be closely attached to the bottom surface of the guiding groove 19 and will be positive. When the teeth 9 of the belt 1 are slidably slidable. Since the friction coefficient of the pair of teeth 9 of the bottom plate portion 37 of the concave member 33 is small, the resistance of the timing belt yoke can be reduced as compared with the case where the teeth 9 are directly supported by the bottom material 丨5. Reference numeral 35 denotes a ventilation path formed at a position opposite to the air passage I of the bottom plate portion 37. The full width of the belt body 3 means the belt width of the timing belt 1 [called, if the tooth width of the tooth 9 is [s], the width (4) of the one-side edge portion 5 is preferably s)/2'. It is set to the range of 5mn〇_. Alternatively, if the thickness of the strip 3 is [t], the [liver LCT" a may be further limited to the range of 3t$ σ $ i5t. Further, the present invention may be modified, modified, or modified in accordance with the knowledge of those of ordinary skill in the art without departing from the scope of the invention. Although the position in which the vent hole 7 penetrates the belt body 3 is shown to be the same as the space between the teeth 9 adjacent to each other (valley), the vent hole 7 can penetrate the teeth 9. The bottom material 15 and the airtight lining 17 may also be integrated. The belt body 3 can also be endless. Further, the shape of the vent hole 7 'arrangement, the number, or the size is a matter that can be appropriately changed. [Embodiment 5] A device 具备 k having a timing belt 1 will be described. _7 is not provided with the film supply means 201, the bag making means 203, the suction conveyance belt 207 of the conveyance bag body 2〇5, and the object & 211 is supplied to the opening part 2〇9 of the bag body 2〇5. The article supply means 213 at the position and the outline of the bagging device 200 of the insertion device 10 201113212. Fig. 8 is a view showing the shape of the opening 209 of the bag body 205 just before the insertion of the article "object 21 1" by the insertion device 215. As shown in Fig. 7, the film supply means 20 1, the film material 217' wound in a roll shape is formed into a shape which is folded in half in the width direction, and is sent to the direction of the arrow T. The bag making device 203 heats the film material 217 which is folded and folded by the heat cutter 219, and then fuses the film materials to each other by the heat of the heat cutter 219, thereby forming a rectangular bag body 2〇5. The portion 22 1 to be fused is a side edge portion of the bag body 2 〇 5 in which the film materials 2 丨 7 which are folded in half are joined to each other. The suction conveyor belt 207 conveys the bag body 205 that is supported by the timing belt 1 by moving a plurality of timing belts supported by the bottom material 丨 5 described above in the direction of the arrow τ. 5 The vent hole 7 of the belt 3' adsorbed to the timing belt 1 is introduced into the vent hole 7 of the timing belt from the suction means. Further, as described in the second embodiment, since the edge portion 5 of the belt body 3 is in close contact with the airtight lining 1 7 ', the negative pressure can be suppressed from the edge portion $ and the bottom surface member i 5 on both sides of the belt body 3. The leakage between the 'therefore has the advantage that there is no need to direct the negative pressure to the ventilation. The output of the attractive slave is unnecessarily increased. Next, the description of the composition of the insertion device 215 will be described. Since the known technology can be applied to the driving source or the guiding means of the following, the details are omitted. For example, as the drive source, an air cylinder, a cylinder, a servo motor, a rotating machine with a speed reducer, or an electric red that rotates the motion # may be applied. As the guiding means, a sliding pair in which the cow is slidably engaged with the guide rail can be applied. As shown in FIGS. 9 and 1B, the insertion device 215 includes a linear motion means 229 for moving the slider 227 back and forth in the horizontal direction, and a rising portion is detachably connected to the slider 227 through the guiding means 23 1 The gate-shaped driven holder 241 of 233, the support body 243 that supports the article 211 at the same height as the bag body 2〇5, the linear track 245 extending in the horizontal direction, and the cam track 247 disposed above the linear track 245 . The linear motion means 229 connects the ball nut 251 screwed to the feed screw 249 to the slider 227, and drives the source to rotate the feed screw 249, thereby moving the slider 227 along the feed screw 249. The end of the feed screw 249 is rotatably supported by the housing of the insertion device 215. The pusher 235 is attached to the frame 237 by the substantially [shaped insertion claw 253 and the feed claw 255 so as to be spaced apart from each other in the direction in which the pusher 235 moves back and forth. The arrows f and R refer to the direction in which the pusher 235 and the slider 227 advance or retreat toward the bag body 2〇5. The rising portion 233 of the driven holder 241 is attached to the driven roller 257 which is rotatably contacted with the straight path 245 or the cam track 247. Further, the driven holder 241 has a frame 237 to which the pusher 235 is fixed to the rising portion 239. The support body 243 is a pair of guide rails 259 made of mountain-shaped lightweight steel. The guide rail 259 supports the article 21 by its flange 261. The flange 263 of the guide rail 259 is used to restrict the article 21! from escaping from the inside of the pair of guides 259. A smooth bottom plate can also be provided between the pair of guide rails 259. The article supply means 213 is shown in FIG. 10 for the endless belt 267 being wound around the rotating wheel 265. However, as long as the article 2 ι can be directed from the direction of the arrow f to the inside of the guide & 259, Limited to the shape of the figure 12 201113212 state. Further, a plurality of rollers 269 are disposed inside the pair of guide rails 259. In order to cause the article 2丨j placed on the endless belt 267 traveling with the drive source, it can be slid by its inertial force immediately after being detached from the endless belt 267. Reference numerals 271 and 273 refer to the introduction portion and the delivery portion of the guide rail 259, respectively. The support plate 275 shown in Fig. 10 is for supporting the linear rail 245 and the pin 277' disposed above the linear rail 245 to be fixed to the housing of the insertion device 215. The cam track 247, as shown in FIG. 9, has an inclined portion 281 that extends the one end 279 in the direction of the arrow F, and a horizontal portion 285 that extends the other end 283 in the direction of the arrow R to bear the one end 279 against the straight line. The posture of the rail 245 is rotatably supported by the pin 277. The inclined portion 28 may be formed in a shape that is inclined upward in the direction of the arrow R. Symbol 287 of Fig. 9 refers to an insertion hole for inserting the pin 277 to the cam track 247. Hereinafter, the operation of the insertion device 215 will be described. The bag making device 203 shown in Fig. 7 sequentially forms a plurality of bag bodies 2 to 5, and then transports the bag bodies 205 by the bag body transporting means 207. Next, when the opening portion 209 of one bag body 2〇5 reaches the front surface of the insertion claw 253 of the pusher 235, the bag body transporting hand 207 stops the conveyance of the bag body 205. In this state, the slider 227 is moved back and forth by the linear motion means 229 of the insertion device 215, and the first to fourth steps of the following operation are performed. In the first step, the driven roller 257 moves in the direction of the arrow F along the straight line 245 from the position indicated by the virtual line 257· at the position of Fig. 9 during the advancement of the slider 227. Fig. 11 (昀 shows the time when the article 211 supplied from the article supply means 213 is stopped while the feeding claw 255 of the pusher 235 is touched during the execution of this step. 13 201113212 Progress 'driven roller 257 Moving in the direction of the arrow ρ, from the lower side thereof to the inclined portion 28 of the cam track 247, since the inclined portion 28 1 is pushed up by the driven roller 257, the cam track 247 is pivoted to the end 279 with the pin 277 as a fulcrum. The direction of the rising direction is rotated. After the driven roller 257 passes through the gap between the one end 279 of the inclined portion 281 and the straight line 245, the cam track 247 rotates in the direction in which the one end 279 descends due to its own weight, and the person ends the end 279. In response to the straight line 245 ^ When the slider 227 reaches the forward limit, the feed claw 255 of the pusher 235 reaches the position indicated by the solid line in the figure u(b). Meanwhile, the insertion claw 253 of the pusher 235 The arrival is indicated by the solid line at the position of Fig. 12(a). As described above, the height of the driven holder 241 in the transition of the driven roller 257 along the straight path 245 is positioned by the linear track 245. Therefore, the insertion claw 253 and the feeding claw 255 of the pusher 235 The height of the self is the same as that of the article 2 11 supported by the support body 2 4 3 . As the slider 2 2 7 advances, the article 211 is pushed into the bag body 2〇5 by the insertion claw 253 to the article 211 1 body. Inserted in the bag body 205. Here, "consistent" means that the insertion claw 253 and the feed claw 25 5 are located on the slightly side of the article 2 。. The second step ' is in the process of the slider 227 retreating from the process. The moving roller 257 moves along the linear track 245 in the direction of the arrow R to reach the one end 279 of the inclined portion 281 of the cam track 247. On the other hand, the insertion claw 253 of the pushing member 235 is inserted into the bag body 2 from the i-th step. The article 211 of the crucible 5 is disengaged and retracted from the bag body 205. The third step 'the slider 227 is further retracted', the follower roller 257 is stepped over the inclined portion 28A. At this point, due to the load of the driven roller 257 14 201113212 Wheel track 247 ′ thus the cam track 247 maintains the posture of the one end Μ to the linear track 245. The driven roller 257 ′ moving in the direction of the arrow ′ rises along the inclined portion 281 of the cam track 247 If the horizontal portion 285 moves, thereby, since the slave keeps & 241 and slave After the wheel 257 rises, it moves horizontally, so the feed claw 255 of the pusher 235 is as shown by the virtual line 255 above the article 211 in the figure <(8). In the fourth step, the driven roller 257 is driven from the cam. The other end 283 of the horizontal portion 285 of the executor 247 is disengaged and returns to the virtual line 257, which is shown at the position of Fig. 9. At this point, the feed claw 255 of the pusher 235 is further retracted from the item 2 ι, and arrives to be virtual. Line 255" is shown at the position of Figure n(b). Further, since the driven roller 257 is detached from the other end 283 of the horizontal portion 285, that is, lowered to the height of the straight line 245, the pusher 235 is also lowered from the driven holder 241. Next, the bag body transport means 207 transfers the bag body 205, and the opening portion 209 of the other bag body 2''' which is attached to the bag body 205 into which the article 21 1 has been inserted reaches the insertion claw 253 of the pusher 235. At the front side, the bag transport means 207 stops the conveyance of the bag body 205. The insertion device 215 executes the first step of the second time. During this period, another item 2 is supplied from the item supply means 213 to the position shown in Figure n(a). On the other hand, the 'feeding claw 255 of the pusher 235 which is advanced from the position shown in Fig. 11(b) by the virtual line 255 is to lock the article 21 1 supplied during the first step of the first time. The article 2 11 is advanced. By performing the second step 2 to the fourth step, the feeding claws of the pusher 235 are 255 15 201113212, that is, the articles supplied during the second step of the second time. Above the 211, at the same time, the insertion claw 253 of the pusher 235, as in the case of the tiger pepper green, the r virtual line 253' is shown in Fig. 12(a), through the articles supplied by the Deng Peng room in the first step of the first time. Above 211, the position indicated by the virtual line 253" is reached. Then, by further performing the steps J to i to the fourth step, the 0° port 211 supplied during the first step of the first step is as shown in FIG. 12(b). The insertion claw 253 3J of 235 is pushed out between the pair of guide rails 259, and is inserted into the opening portion 2〇9 of the bag body 2〇5 shown in Fig. 8 . Further, when the article 211 is inserted into one bag 205, the bag transporting means 2〇7 repeatedly transports and stops the bag body 205, so that the insertion device 215 can be sequentially supplied from the article supply means 213. The plurality of articles 2n are respectively inserted into a plurality of pockets 2〇5 conveyed by the suction conveyor 207. The insertion device 2 1 5 ' is configured to set a pair of movable guides 3 于 between a pair of guides 259 and the opening 2 〇 9 , preferably a pair of movable guides, for example, to set the respective protruding ends 303 It is wedge-shaped and forms a profile into a groove shape that is inward of each other. Further, the insertion device 215 is provided with a guiding means for guiding the pair of movable guides 3〇1 to the directions of the arrows F and R, and for moving the pair of movable guides 3〇1 forward and backward. The guiding means of the direction is preferred. At this time, the movable guide 301 is retracted from the position shown in the figure so that the protruding end 303 of the movable guide 301 is detached from the opening 2〇9 of the bag body 2〇5, and in the first step, the article 21 1 is just one from the first step. Prior to pushing out between the guide rails 259, the movable guides 301 are advanced so that the respective projecting ends 3〇3 enter the opening portions 2〇9. Thereby, the opening portion 2〇9 can be opened larger than the size of the article 2丨丨, and the defect that the article 211 to be inserted into the bag body 205 is caught by the opening portion 2〇9 16 201113212 can be prevented in advance. In addition, the suction pad 3〇7 may be disposed in the front of the suction tube, and guided to the adsorption bag body 2 through the conduit 305 by the oblique introduction means from the negative pressure of the lower end 塾307 of the conduit 3二5 of the Erfeng square. Before the movable guide 301 is just advanced, the finger is attracted so that the opening 209 is opened above the timing belt i. Further, when the pair of movable guides 3〇1 are retracted from the bag body 2〇5, the respective distal ends τ may be tilted by 1 bar to the direction in which they approach each other, and the opening end 303 enters the opening portion. 20Q r main.,, & 'The movable guide 301 is operated in such a manner that the intervals of the respective protruding ends 303 are pulled apart. Thereby, the tension is generated in the opening portion 2〇9 of the bag body 2〇5, and the slack of the opening portion 2 (10) can be prevented. In addition, the present invention may be embodied in various modifications, alterations, and modifications without departing from the spirit and scope of the invention. The film supply means 201 and the bag making means 203' shown in Fig. 7 may be omitted and the article 211 may be inserted into the ready-made bag. At this time, the ready-made bag body may be directly supplied to the timing belt i of the suction conveyor belt 207. The feed screw 249 and the ball nut 25 1 may be omitted, and the application of the β-piece 227 to the driving source of the piston rod may be applied. As the linear motion means 229, the speed at which the suction conveyor 207 is transported to the bag body 205 can be multiplied, and the two C-packages 215 arranged in the direction of the arrow F can simultaneously insert the article 211 into two or more pockets. 2 () 5. Further, the bag sealing device that seals the opening 209 of the bag body 2〇5 after the insertion device 215 inserts the article 211 into the bag body 205 may be disposed on the suction conveyor belt 2〇7 to transport the inserted article 2 1 1 . The bag body 205 is on the way. 17 201113212 The present invention is a technique useful for the transport and positioning of various articles. Further, since the present invention can insert an article at a high speed without relying on a human hand, it is a useful technique for loading an article into a plurality of pockets, for example, by mailing a catalogue by direct mail.
