200934637 九、發明說明 【發明所屬之技術領域】 本發明是關於將標籤搬運到嵌入成型機的模具內的標 籤搬運方法及標籤搬運裝置。 【先前技術】 曰本特許第2797043號公報（專利文獻1)的第1圖及 φ 第4圖中，揭示有對類模芯的外圍藉著吸引手段的吸氣捲 繞標籤，在捲繞於類模芯的狀態下將標籤供給至射出成型 模具內對習知射出成型模具的標籤供給裝置及方法。該先 前的技術是以朝著橫向的狀態配置收納著複數片標籤的標 籤料斗。並且使用具備吸盤的吸附裝置，從設置在標籤料 斗一方端部的標籤取出口以吸盤吸附標籤水平方向取出標 籤。隨後，捲繞取出後的標籤朝載台移動標籤，對類模芯 進行標籤的捲繞。 【發明內容】 〔發明所欲解決的課題〕 從橫向姿態的標籤料斗水平抽取標籤的構成隨著收容 在標籤料斗的標籤數量的減少，會減小吸盤抵接在標籤表 面時的反力。因此，會妨礙吸盤進行正確的吸附使得標籤 有脫落之虞。因此，可考慮將標籤料斗保持在鉛直縱向姿 態，從其上端開口部以吸盤鉛直朝上抽取標籤搬運的方 法。但是，一但採用此一方法時，即使因層疊在標籤料斗 -5- 200934637 收仓標籤的減少而必須進行補充時，在標籤搬運裝置的運 轉中因吸盤的妨礙而不能從上端開口部補充標籤。因此， 對標籤料斗每進行標籤的補充時，必須停止標籤搬運裝置 的運轉’而導致嵌入成型生產效能的降低。 另一方面’可考慮對標籤料斗不採用補充標籤的方 法’而是以更換標籤料斗的方式。但是，即使採用此一手 法’不但造成標籤料斗更換上的繁雜，更換時仍必須停止 標籤搬運裝置的運轉，仍就不會改變嵌入成型生產效能的 降低。 又’專利文獻1記載的技術是以吸附裝置吸附標籤 後，將標籤在吸附狀態下移動至捲繞載台，因此標籤料斗 的配置位置和吸附裝置的構造會受限定。具體而言，從標 籤料斗取出標籤的取出裝置的構造，及將取出後的標籤捲 繞在載台的標籤搬運裝置的構造由於分別受到限定，因此 會有導致標籤供給裝置的設計的自由度降低的問題。 本發明的目的是提供嵌入成型系統的運轉中可對標籤 料斗執行標籤的補充，藉此可避免嵌入成型系統生產效能 降低的標籤之搬運方法及標籤搬運裝置。 除了上述目的，本發明的目的是提供作爲從標籤料斗 取出標籤的標籤取出機構的構造，及將捲繞取出後的標籤 搬運到載台的標籤搬運裝置的構造是可採用任意構造的設 計自由度高的標籤搬運裝置。 〔解決課題的手段〕 -6- 200934637 本發明涉及的標籤之搬運方法爲嵌入成型系統的標籤 之搬運方法。本發明的標籤之搬運方法，具有從層疊收容 在標籤料斗的複數片標籤將1片標籤以標籤取出機構從標 籤料斗的下部分離後抽取的特徵。 根據本發明，即使在包含標籤取出機構的搬運裝置的 運轉中，可以從標籤料斗的上部補充標籤，因此可避免嵌 入成型系統生產效能的降低。 0 將與標籤料斗所抽取1片標籤對向的一對端緣部以至 少一對的端緣部夾持移送裝置夾持後移送爲佳。如此一 來，藉著至少一對端緣部夾持移送裝置，可賦予標籤預定 的張力予以移送，因此可防止標籤產生皺折與扭曲，有助 於藉標籤搬運裝置所成型的嵌入成型工件成型品品質的提 升。 以將標籤料斗存放在存放部爲佳。該存放部具備藉開 門力容許安全門的開門且可藉著開門力的解除自動關閉安 Φ 全門的關門手段，並且即使安全門開門時也可構成使包含 標籤取出機構及端緣部夾持移送機構的標籤搬運裝置運 轉。藉此，由於在標籤料斗進行標籤補充成型作業操作員 開啓安全門時，仍可繼續進行包含標籤取出機構及端緣部 夾持移送裝置之標籤搬運手段的運轉，因此可避免嵌入成 型系統生產效能的降低。又，標籤補充後成型作業操作員 即使未進行關門操作，仍可進行開門力的解除，即手從安 全門離開即可藉關門手段自動關閉安全門以確保安全。因 此，不會因成型作業操作員疏忽或忘記而導致安全上的問 200934637 題。 標蕺料斗是以具備避免層叠收容的複數片標籤的重量 形成過剩重量對最下層的標籤造成負荷的負荷重量限制手 段爲佳。藉此，對最下層的1片標籤不致產生過勝負荷， 因此即使使用層疊收容片數大的大型標籤料斗，仍可容易 從其下部將最下層的標籤分離抽取。又因爲使用層疊收容 片數大的大型（長尺寸）的標籤料斗，可以抑制每單位時間 的標籤補充次數，可減輕成型作業操作員的負擔。 以端緣部夾持移送裝置夾持著從標籤料斗的下部藉標 籤取出機構分離抽取1片標籤的狀態移送到標籤供給裝置 爲止，標籤供給裝置只須將接受自端緣部夾持移送裝置的 1片標籤供給至嵌入成型機的模具，即可藉著嵌入成型機 效能良好地並可確保成型作業操作員安全地進行高品質嵌 入成型工件成型品的成型。 另外，本發明涉及的標籤搬運裝置是包含標籤料斗所 構成，從層疊收容在標籤料斗的複數片標籤抽取1片的標 籤，將標籤供給至嵌入成型機所具備的模具的標籤供給裝 置。本發明的標籤搬運裝置具備從標籤料斗的下部分離抽 取1片標籤的標籤取出裝置。根據本發明的標籤搬運裝 置，即使在含嵌入成型機、標籤供給裝置及標籤取出機構 之標籤搬運裝置的運轉中，仍然可以從標籤料斗的上述補 充標籤，可避免嵌入成型機系統生產效能的降低。 加以具體化的本發明標籤搬運裝置在將收納有多數片 標籤的標籤料斗取出的標籤搬運到捲繞在類模芯的捲繞架 -8- 200934637 台之前’從裝塡著標籤的標籤料斗分離標籤取出時，藉著 標籤定位機構將標籤的位置定位至正確的位置。因此不會 降低標鐵對類模芯的定位精度。 標籤定位機構在使用具備作爲標籤其一部分大致形成 線對稱的中心線的標籤時，以構成與標籤的前端緣及後端 緣抵接進行標籤的定位爲佳。標籤定位機構一旦爲以上構 成時，可簡單且確實進行標籤的定位。 Φ 更加以具體化的本發明的標籤搬運裝置，包含··收納 多數片標籤的標籤料斗，及標籤取出機構。標籤搬運裝置 在標籤取出機構與標籤供給機構之間，具備：將標籤料斗 所抽取的標籤以預定的姿勢放置到中間架台上的標籤定位 機構，及將放置在標籤定位機構的中間架台上的標籤搬運 到標籤供給裝置的捲繞架台的標籤搬運機構。 標籤取出機構是從標籤料斗逐片地取出標籤，將標籤 放置在中間台架上。標籤搬運機構是將中間架台上的標籤 φ 搬運到標籤捲繞在類模芯的捲繞架台上。標籤供給裝置在 捲繞架台中，將標籤捲繞在類模芯的外圍並在射出成型模 具內捲繞於類模芯的狀態下供給標籤。尤其是以具備從中 間架台將標籤取出機構所取出來標籤的位置定位在正確位 置的標籤定位機構爲佳。標籤取出機構和標籤搬運機構之 間一旦設置放置標籤的中間架台時，標籤取出機構的構造 及標籤搬運機構的構造可以是任意的構造。因此可以提高 標籤供給裝置設計的自由度。並且即使設置中間架台’本 發明中可以使中間架台上所取出來標籤的位置藉著標籤定 -9- 200934637 位機構定位在正確的位置，不致使得標籤對類模芯的定位 精度降低。 標籤定位機構的構造爲任意的構造。例如，可以標籤 定位機構作爲具備第1止動機構和第2止動機構的構造。 第1止動機構可以阻止標籤取出機構從中間架台所取出的 標籤在上述中間架台的表面滑動移動到上述捲繞架台定位 的進行方向，並且第2止動機構可阻止抵接第1止動機構 的標籤回到和進行方向相反的方向。上述的標籤定位機構 中，在第1止動機構和第2止動機構之間夾著標籤，藉以 決定標籤的位置。因此，可以簡單的構成進行標籤的定 位。並且第1及第2止動機構構成本發明的引導部。 再者，具體的第1止動機構，可具備；與標籤抵接的 第1止動部，及只在發揮止動功能時將第1止動部定位在 中間架台上，不需要發揮止動功能時，使得第1止動部退 避到容許標籤通過的退避位置的退避機構的構造。且具體 的第2止動機構，具備：與標籤抵接的第2止動部，及只 在發揮止動功能時將第2止動部定位在中間架台上，不需 要發揮止動功能時，使得第2止動部退避到容許標籤通過 的退避位置的第1進退機構的構造。使用上述構造之第1 及第2止動機構時，根據需要可以將第1及第2止動部定 位在中間架台上，因此，第1及第2止動機構的存在不會 導致使得標籤供給裝置設計自由度降低的大的原因。 又，第1止動機構的第1進退機構是在標籤從標籤取 出機構放置到中間架台之前將第1止動部定位在中間架台 -10- 200934637 上。並且，第2止動機構的第2進退機構是在標籤從標籤 取出機構放置在中間架台之後，到標籤抵接在第1止動部 瞬間爲止前，預先使得第2止動部位於退避位置，在標籤 抵接到第1止動部的瞬間前使第2止動部定位在中間架台 上。如此一來，第2止動部在標籤放置於中間架台上時不 會造成妨礙。並可以第1止動部確實停止放置在中間架台 上的標籤。另外，可藉著第2止動部確實阻止標籤朝著相 n 反方向移動，將標籤定位在正確位置。 並且，也可以具備將標籤推壓到中間架台矯正標籤捲 邊（翹曲）的壓緊手段。設置上述的壓緊手段時，搬運前可 以矯正標籤的捲邊（翹曲），更可以提高標籤的捲繞精度。 另外設置壓緊手段的場合，第1及第2止動機構是構 成在壓緊手段將標籤朝向中間架台推壓時，使第1及第2 止動部退避到退避位置。如此一來，即使具備第1及第2 止動機構仍可進行標籤的推壓。 Φ 標籤搬運機構只要可藉著標籤定位機構維持著決定後 的標籤位置（朝進行方向的標籤位置），將標籤搬運到捲繞 架台的機構即可不論任何的構造。例如，標籤搬運機構可 以是把持與標籤進行方向正交的寬度方向兩端的一對夾 具；使一對夾具在對應中間架台的第1位置和對應捲繞架 台的第2位置之間滑動的滑動機構；及控制至少一對夾具 及滑動機構的動作的動作控制裝置所構成。該具體的標籤 搬運機構構成端緣部夾持移送裝置。此時，動作控制裝置 如以下控制動作。首先，以一對夾具把持著和標籤定位機 -11 - 200934637 構所定位之標籤進行方向正交的寬度方向兩端。接著使得 —對夾具從第1位置滑動到第2位置’隨後打開一對夾具 將標籤放置在捲繞架台上。接著進行使一對夾具從第2位 置滑動到第1位置的動作。以一對夾具把持著標籤將標籤 從中間架台搬運到捲繞架台時，可維持著定位狀態的姿勢 (位置關係），不致使標籤彎曲或扭轉可進行搬運。因此’ 不需要以捲繞架台進行標籤的再次定位，無須進行矯正。 標籤取出機構可以是任意的取出構造。以使得1片標 籤露出的標籤取出口向下的姿勢配置標籤料斗的場合，作 爲標籤取出機構是使用將取出構造配置在標籤取出口的下 方，從標籤取出口取出1片標籤，將標籤送出到中間架台 所構成的構造即可。 再者，此時的標籤取出機構可以爲具備配置在標籤取 出口的下方之可移動的吸附部及吸附部移動裝置的吸附裝 置，及標籤送出裝置所構成。在吸附部移動裝置吸附從標 籤取出口露出的1片標籤的吸附位置和吸附部位在待機狀 態的待機位置之間，移動吸附部。並且標籤送出裝置在吸 附部從吸附位置移動到待機位置的過程，將標籤取出口所 抽出的1片標籤朝著中間架台在不拘束標籤的狀態下送 出。採用以上的構造時，可在標籤料斗的下方精巧地配置 標籤取出機構。其結果，同時可獲得標籤供給裝置的精巧 化構造。 另外，吸附裝置可以使用具備隔開間隔所配置的2個 吸附管嘴作爲吸附部，並且從2個吸附管嘴吸引空氣，產 -12- 200934637 生吸附力所構成的裝置。並且該吸附裝置在吸附部從吸附 位置移動到待機位置的過程中，從吸附管嘴吸引空氣到達 標籤送出裝置的動作範圍爲止。又吸附部移動裝置藉著以 迴轉中心爲中心的擺動運動，構成使吸附部在吸附位置和 待機位置之間移動。採用以上的構成時，只以吸附管嘴的 迴轉動作即可將標籤從標籤料斗取出，標籤取機構的構造 變得簡單。 Φ 又，標籤送出裝置是以使用具備被配置在和標籤取出 口對向的對向位置，接受來自標籤取出口所抽出的1片標 籤並爲了將標籤送出到中間架台而轉動的具有環形皮帶的 搬運輸送帶裝置爲佳。使用此構造的標籤送出裝置時，不 需要大的設置空間，即可將取出後的標籤順利送出到中間 架台。 本發明也可以掌握嵌入成型系統的標籤的供給方法。 本發明的標籤供給方法是從收納有多數片標籤的標籤料斗 〇 逐片取出標籤並將標籤放置到中間架台上，隨後將中間架 台上的上述標籤搬運到標籤捲繞在類模芯的捲繞架台，於 捲繞架台將標籤捲繞在類模芯的外圍，捲繞在類模芯的狀 態下供給標籤至射出成型模具內。並且，於中間架台將標 籤的位置定位在正確的位置。且在標籤的位置定位之前或 之後，將標籤推壓到中間架台矯正標籤的捲邊（翹曲）。之 後’保持著矯正後的狀態將標籤搬運到捲繞架台。 〔發明效果〕 -13- 200934637 根據本發明’嵌入成型系統的運轉中可執行標籤的補 充’可避免嵌入成型系統生產效能的降低。 【實施方式】 以下’根據圖示說明本發明運用在嵌入成型的較佳實 施形態。第1圖是表示具備本發明標籤搬運裝置的嵌入成 型系統的實施形態之一例的槪略上視圖，第2圖爲第1圖 的Π-Π箭頭方向圖’第3圖是表示嵌入成型工件成型品的 一例的放大縱剖視圖。並且圖示是用於說明的圖，爲容易 理解，將其一部分誇張描繪’並且各部的尺寸比例和實際 的尺寸比例不同。 第1圖、第2圖、第3圖中，嵌入成型系統丨，具 備：射出成型機（嵌入成型機）2;對嵌入成型機2所具備 的固定模具21供給標籤L的標籤供給裝置3;及包含從 層疊收容有多數片標籤L的標籤料斗4抽取最下層的1片 標籤L的標籤取出機構50及將標籤取出機構5〇取出到中 間架台13上的標籤L搬運到標籤供給裝置3的標籤搬運 機構51的標籤搬運裝置6。 嵌入成型機2是作爲第3圖表示的標籤L和使得該標 籤L在表面一體化之合成樹脂製杯子或截錐形容器等成型 品1 0所構成的嵌入成型工件成型品1 1射出成型之用。如 第1圖表示，具有：安裝在習知的固定台板20上的固定 模具21’及安裝在活動台板22的活動模具23，活動模具 23是藉著合模機構24朝向固定模具21進退（第1圖的箭 -14- 200934637 頭XI、X2方向）。 固定模具21具有和杯子或截錐形容器等所構成之嵌 入成型工件成型品11的外面一致的截錐形凹部21a°該 凹部21a的周圍壁，例如複數個吸•送氣通路（省略圖示） 朝徑向外側延伸連通，各吸•送氣通路是藉著未圖示的轉 換閥連通於吸氣手段和送氣手段（皆未圖示）。並且’截錐 形凹部21a連通於射出機構25» φ 活動模具23在其前端突設有和杯子或截錐形容器等 所構成的嵌入成型工件成型品11內面一致的截錐形的模 芯26。嵌入成型機2的側方設置有標籤搬運裝置6。 標籤供給裝置3，具備：類模芯30;將此類模芯30 安裝在和前端側的固定模具21對向面上的第1把持臂 31;吸附墊32;將此吸附墊32安裝在和前端側的活動模 具23對向面上的第2把持臂33:組裝第1、第2把持臂 31、33使其可朝著第1圖的箭頭XI、X2方向及Yl、Y2 〇 方向移動的成型品取出機34及組裝在該成型品取出機34 使第1、第2把持臂31、33朝著上述箭頭XI、X2方向及 Yl、Y2方向進退的進退裝置（省略圖示）。 類模芯30的外形狀和嵌入成型工件成型品11(參閱 第3圖）的外形狀一致，其外面具備多數個吸氣孔30a，各 吸氣孔30a是經由未圖示的轉換閥連通於吸氣手段和送氣 手段（皆未圖示）。並且，吸附墊32是經未圖示的轉換閥 連通於吸氣手段和送氣手段（皆未圖示）。 如第1圖、第2圖表不’標籤料斗4被以重叠狀態收 -15- 200934637 納有多數片標籤L之收納部41傾斜的狀態配置。並且標 籤料斗4在收納部41的下側端部具有標籤取出口 4a，上 側端部具備標籤塡充口 4b。標籤取出口 4a自然地使標籤 不致落下支撐著最下部的標籤。本實施形態的標籤料斗4 是以傾斜的姿勢配置在存放部8內，使標籤取出口 4a對 向於標籤搬運裝置6的標籤取出機構50，並使得構成標 籤塡充口 4b的上端部開口較標籤取出口 4a後退到與方向 D的相反側方向。 標籤料斗4被存放在具備安全門81的存放部8。存 放部8爲安全門81和框架82所構成。安全門81具有一 面開口的箱形狀。框架82具有可收納標籤搬運裝置6整 體並收納標籤料斗4下側半部的構造。框架82的後方端 部形成有開口部82 A(第2圖）。安全門81是藉一對鉸鏈 機構83安裝在框架82來封閉開口部82 A。一對鉸鏈機構 83被沿著朝開口部82A的上下方向延伸的一邊在上下方 向隔開間隔配置，連結著安全門81與框架82。 如第1圖表示，一對的鉸鏈機構83上設有以彈簧作 爲驅動源的關門手段84。關門手段84根據成型作業人員 爲了開啓安全門8 1對安全門8 1所施加的開門力，容許一 邊壓縮彈簧一邊開啓安全門81 (參照第2圖的2兩點虛 線）。並且關門手段84構成一旦解除開門力時，藉著被壓 縮彈簧的恢復力自動關閉安全門81。再者，本實施形態 的系統即使形成安全門81已開啓的狀態，仍可持續進行 含標籤取出機構50及標籤運送機構51的標籤搬運裝置6 -16- 200934637 的運轉。因此，爲了補充標籤L到標籤料斗4，成型作業 人員即使開啓安全門81’仍可持續進行含標籤取出機構 50及標籤運送機構51的標籤搬運裝置6的運轉，因此可 避免嵌入成型系統1之生產效能的降低。又，標籤L的補 充後成型作業人員即使未進行關門操作，僅藉著開門力的 解除’即手從安全門8 1離開，即可藉著關門手段84自動 地關閉安全門8 1以確保安全。因此，根據本實施的形 態，成型作業人貝不致因關門操作的疏忽或忘記而損及安 全。並且在系統的外側設置柵欄的場合可以不需要安全門 81 〇 標籤料斗4的構造只要是可以從標籤取出口 4a抽出 標籤即可’任意的構造皆可。例如，第7圖及第8圖表示 具體的標鑛料斗4具備一對的側壁4c、4c，及連結一對 側壁4c、4c的底壁4d。該標籤料斗4在和底壁4d對向 的部分具備開口部4e。因此從上方往標籤料斗4看去 〇 時，如第8圖表示，可看見標籤L。並在一對側壁4c、4c 上具備標籤取出口 4a的附近與最下層的標籤L接觸支撐 著標籤的標籤支撐部4f。又標籤料斗4的一對側壁4c的 內壁部’從接近標籤取出口 4a的位置朝向標籤塡充口 4b 隔開預定的間隔，設有以實線表示的彼此相對的一對嵌合 溝槽40 ° 對嵌合溝槽40可以通過開口部4e自由嵌卸 地嵌入構成負荷重量限制手段的隔板41的寬度方向兩端 部。如第8圖表示，接近標籤取出口 4a位置的一對嵌合 溝槽40嵌合隔板41的場合，鄰接著標籤取出口 4a的最 -17- 200934637 下層標籤L不會有來自隔板41存在於標籤塡充口 4b之間 區域的多數標籤L的重量的負荷。可容易分離抽取最下層 的標籤L。因此，可以使用標籤L的層疊收容片數大的大 型（長尺寸）的標籤料斗4。其結果，可抑制每單位時間標 籤L的補充次數，可減輕成型作業人員的負擔。設置隔板 41的場合’在系統運轉的中途，隔板41下方的標籤量形 成某程度減少時，抽去隔板41，使隔板41上方的標籤L 落下到隔板41的下側。並且隨後，再度將隔板41嵌合到 嵌合溝槽41。實際的隔板41是採用金屬製厚度薄的隔 板。因此即使隔板41再***的場合，尤其不會造成阻 礙。並且收納在標籤料斗4的標籤量爲適量，或者標籤的 重量卿的場合，可不須採用隔板41。 再者’第7圖及第8圖表示，也可以如兩點虛線表 示，隔開預定間隔在標籤料斗4的長方向隔開預定間隔， 複數處設置嵌合溝槽40，將兩點虛線表示的隔板41自由 嵌卸地從上側嵌入到各嵌合溝槽40內。即，也可以採使 用複數隔板（負荷重量限制手段）41的構成。此時，在補充 標籤時，只要從位在下方的隔板41依序進行抽取和再插 入即可。並且當然也可以使隔板41的***及抽取自動 化。 本實施的形態中，標籤料斗4是以使得1片標籤露出 的標籤取出口 4a向下的姿勢配置，因此標籤取出機構50 是被配置在標籤取出口 4a的下方，構成可從標籤取出口 4a取出1片的標籤L(分離抽取），將標籤L送出到中間架 200934637 台13。並且’標籤搬運機構51是作爲將放置在中間架台 13上的標籤搬運供給到標籤供給裝置3的捲繞架台14爲 止之用。本實施形態中，藉著標籤取出機構50;標籤搬 運機構51;及在中間架台13將以標籤取出機構50所取 出來的標籤L的位置定位在正確位置的標籤定位機構7, 藉此構成標籤搬運機構6。 本實施形態的標籤搬運機構51是由藉著標籤取出機 φ 構50夾持著從標籤料斗4的下部所取出標籤L的寬度方 向兩端緣部（第1圖的箭頭W方向的兩端緣部），將其標籤 L移送到標籤供給裝置3對類模芯30的交接位置（後述的 捲繞架台14)爲止的端緣部夾持移送裝置所構成。 如第4圖、第5圖詳細表示，本實施形態中，標籤取 出機構50被配置在標籤取出口 4a的下方，爲具備可移動 的吸附部52及吸附部移動裝置53的吸附裝置50A，及標 籤送出裝置50B所構成。標簾送出裝置50B，具有：鈹配 〇 置在和標籤取出口 4a對向的對向位置，接受從標籤取出 口 4a所抽出的1片標籤L並轉動將標籤L送出到中間架 台13用的兩組環形皮帶（輸送帶）54、55。以向上的斜度 延伸彼此平行的兩組環形皮帶54、55背隔開預定的間隔 配置。該等環形皮帶54、55的原動滑輪54a及原動滑輪 55a、從動滑輪54b及從動滑輪55b分別被固定在朝寬度 方向（第5圖的箭頭W方向）延伸的轉軸56上。原動滑輪 54a、55a是根據來自控制裝置12的控制訊號藉著可數字 控制的伺服馬達等的電動馬達56 a(第5圖）旋轉驅動。兩 -19- 200934637 組的環形皮帶54、55之間的空間配置有吸附裝置52。 吸附裝置52具備以隔開間隔所配置的2個吸附管嘴 52a作爲吸附部52。吸附部移動裝置53是在吸附部52吸 附從標籤取出口 4a露出的1片標籤L的吸附位置（第4圖 中，以實線表示的吸附部52存在的位置）和吸附部52位 於待機狀態的待機位置（第4圖中，以虛線表示的吸附部 52存在的位置）之間’以迴轉中心c爲中心使吸附部52 擺動。吸附裝置52在吸附部52從吸附位置移動到待機位 置的過程中，從2個吸附管嘴52a吸引空氣到達標籤送出 裝置5 OB的動作範圍爲止。亦即，藉著2個吸附管嘴52a 吸引空氣所產生的吸附力結合1片的標籤L和吸附部 52。並且在吸附部52從吸附位置迴轉到待機位置爲止的 過程，從標籤料斗4抽出標籤L，在標籤到達標籤送出裝 置50B上的瞬間前，停止從吸附管嘴53a吸引空氣。其結 果，標籤L搭在標籤送出裝置50B的搬運輸送帶裝置的 環形皮帶54、55之上，藉旋轉的環形皮帶54、55送出到 中間架台1

Field of the Invention The present invention relates to a label transport method and a label transport device for transporting a label into a mold of an insert molding machine. [Prior Art] In the first diagram and the φ fourth diagram of Japanese Patent No. 2970034 (Patent Document 1), an air-wound label is attached to the periphery of the core-like core by suction means, and is wound around A label supply device and method for feeding a label to a conventional injection molding die in a state in which a mold core is supplied to an injection molding die. This prior art technique is to arrange a label hopper in which a plurality of labels are accommodated in a state of being horizontal. Further, using the suction device provided with the suction cup, the label is taken out from the label take-out port provided at one end portion of the label hopper in the horizontal direction of the suction cup suction label. Subsequently, the unwound label is moved toward the stage, and the label-like core is wound. [Problem to be Solved by the Invention] The configuration of extracting the label horizontally from the label hopper in the horizontal posture reduces the reaction force when the suction cup abuts against the label surface as the number of labels accommodated in the label hopper decreases. As a result, the suction pad is prevented from being properly absorbed, causing the label to fall off. Therefore, it is conceivable to maintain the label hopper in a vertical longitudinal posture and to extract the label from the upper end opening portion with the suction cup vertically upward. However, when this method is used, even if it is necessary to replenish the labeling hopper-5-200934637, the labeling device cannot be replenished from the upper end opening due to the obstruction of the suction cup during the operation of the label conveying device. . Therefore, when the label hopper is replenished for each label, the operation of the label transporting device must be stopped, resulting in a reduction in the productivity of the insert molding. On the other hand, the method of replacing the label hopper with the label hopper may be considered. However, even if this method is used, not only is the label hopper replacement complicated, but the label handling device must be stopped during replacement, and the reduction in the productivity of the insert molding is not changed. Further, in the technique described in Patent Document 1, since the label is adsorbed by the adsorption device and the label is moved to the winding stage in the adsorbed state, the arrangement position of the label hopper and the structure of the adsorption device are limited. Specifically, the structure of the take-out device for taking out the label from the label hopper and the structure of the label transport device for winding the removed label on the stage are limited, respectively, and thus the degree of freedom in designing the label supply device is lowered. The problem. SUMMARY OF THE INVENTION An object of the present invention is to provide a label-removing method for labeling a hopper in operation of an insert molding system, thereby avoiding a label carrying method and a label handling device which have reduced productivity in an insert molding system. In addition to the above object, an object of the present invention is to provide a structure of a label take-out mechanism that takes out a label from a label hopper, and a structure of a label transport device that transports the packaged label to a stage, and can adopt a design freedom of any configuration. High label handling device. [Means for Solving the Problem] -6- 200934637 The method for transporting a label according to the present invention is a method of transporting a label embedded in a molding system. The label transporting method of the present invention has a feature of separating one label from a lower portion of the label hopper by a plurality of labels attached to the label hopper, and extracting the label from the lower portion of the label hopper. According to the present invention, even in the operation of the conveying device including the label take-up mechanism, the label can be replenished from the upper portion of the label hopper, so that the reduction in the production efficiency of the insert molding system can be avoided. 0 It is preferable to transfer the pair of end edge portions facing the one label of the label hopper with at least one pair of end edge portions of the transfer device. In this way, by the at least one pair of edge portions holding the transfer device, the predetermined tension of the label can be transferred and transferred, thereby preventing the label from being wrinkled and twisted, and facilitating the molding of the insert molding formed by the label handling device. Product quality improvement. It is preferable to store the label hopper in the storage section. The storage unit is provided with a door closing mechanism for allowing the safety door to open by the door opening force, and can be automatically closed by the release of the door opening force, and can be configured to include the label take-out mechanism and the edge edge clamping transfer mechanism even when the safety door is opened. The label handling device operates. Thereby, since the operator can open the safety door when the label hopper performs the label refilling operation, the operation of the label conveying means including the label take-out mechanism and the edge-edge nip conveying device can be continued, thereby avoiding the production efficiency of the insert molding system. reduce. In addition, after the label is replenished, the operator of the molding operation can release the door opening force even if the door closing operation is not performed, that is, the hand can be automatically closed by the door closing means to ensure safety by leaving the door. Therefore, there will be no safety question 200934637 due to the negligence or forgetting of the molding operator. The standard hopper is preferably a load weight limiting means having a weight which prevents the stacking of the plurality of sheets from being stacked and which causes an excess weight to load the lowermost label. As a result, there is no excessive load on the lowermost one label. Therefore, even if a large label hopper having a large number of stacked sheets is used, the lowermost label can be easily separated and extracted from the lower portion. Further, since a large (long-sized) label hopper having a large number of stacked accommodating sheets is used, the number of times of label replenishment per unit time can be suppressed, and the burden on the molding operation operator can be reduced. The end edge portion holding and conveying device holds the state in which the label is separated and removed from the lower portion of the label hopper by the label taking mechanism, and is transferred to the label supply device. The label supply device only needs to receive the transfer device from the end edge portion. The one-piece label is supplied to the mold of the insert molding machine, and the insert molding machine can perform well and ensure that the molding operator can safely perform molding of the high-quality insert molding workpiece. In addition, the label conveying device according to the present invention includes a label hopper, and a label is supplied from a plurality of sheets of labels attached to the label hopper, and the label is supplied to a label supply device of a mold provided in the molding machine. The label transport device of the present invention includes a label take-out device that separates and extracts one label from the lower portion of the label hopper. According to the label transporting apparatus of the present invention, even in the operation of the label transporting apparatus including the insert molding machine, the label supply device, and the label take-out mechanism, the above-described supplementary label of the label hopper can be prevented, and the production efficiency of the insert molding machine system can be prevented from being lowered. . The label transport device of the present invention, which is embodied by the label hopper that takes out a plurality of label hoppers, is transported to the label hopper of the label before being carried around the winding frame -8-200934637 of the core-like core. When the label is removed, the label positioning mechanism is used to position the label to the correct position. Therefore, the positioning accuracy of the standard iron core is not lowered. When the label positioning mechanism uses a label having a center line which is substantially line-symmetric as a part of the label, it is preferable to form a label by abutting against the front end edge and the rear end edge of the label. Once the label positioning mechanism is constructed as described above, the label positioning can be performed simply and surely. Φ More specifically, the label transport device of the present invention includes a label hopper for storing a plurality of sheets of labels, and a label take-up mechanism. The label transport device includes, between the label take-up mechanism and the label supply mechanism, a label positioning mechanism that places the label extracted by the label hopper in a predetermined posture on the intermediate frame, and a label to be placed on the intermediate frame of the label positioning mechanism The label transport mechanism that is transported to the winding stand of the label supply device. The label removal mechanism removes the label piece by piece from the label hopper and places the label on the intermediate stage. The label transport mechanism transports the label φ on the intermediate frame to the winding frame of the mold core. The label supply device feeds the label in a state in which the label is wound around the periphery of the core-like core and wound around the core-like core in the injection molding mold. In particular, it is preferable to position the label positioning mechanism at a position where the label is taken out from the intermediate frame by the label take-out mechanism. When the intermediate stage on which the label is placed is provided between the label take-up mechanism and the label transport mechanism, the structure of the label take-up mechanism and the structure of the label transport mechanism can be of any configuration. Therefore, the degree of freedom in designing the label supply device can be improved. And even if the intermediate gantry is provided, the position of the label taken out on the intermediate gantry can be positioned at the correct position by the label -9-200934637 position mechanism, so that the positioning accuracy of the label on the core-like core is not lowered. The configuration of the label positioning mechanism is an arbitrary configuration. For example, the label positioning mechanism can be configured to have the first stopper mechanism and the second stopper mechanism. The first stopping mechanism can prevent the label taken out from the intermediate frame by the label taking-out mechanism from slidingly moving on the surface of the intermediate stage to the direction in which the winding frame is positioned, and the second stopping mechanism can prevent the first stop mechanism from being abutted The label returns to the opposite direction. In the above-described label positioning mechanism, a label is interposed between the first stopper mechanism and the second stopper mechanism to determine the position of the label. Therefore, the positioning of the label can be made simply. Further, the first and second stopper mechanisms constitute the guide portion of the present invention. Further, the specific first stopper mechanism may include a first stopper portion that abuts against the label, and a first stopper portion that is positioned on the intermediate frame only when the stopper function is exerted, and does not need to be stopped. In the case of the function, the first stopper is retracted to the structure of the retracting mechanism that allows the retracted position through which the label passes. Further, the specific second stopper mechanism includes a second stopper that abuts against the label, and when the second stopper is positioned on the intermediate frame only when the stopper function is exerted, and the stop function is not required to be performed, The structure of the first advancing and retracting mechanism that retracts the second stopper to the retracted position at which the tag is allowed to pass. When the first and second stopper mechanisms of the above configuration are used, the first and second stoppers can be positioned on the intermediate frame as needed. Therefore, the presence of the first and second stoppers does not cause the label to be supplied. The reason for the reduced freedom of design of the device. Further, the first advancing and retracting mechanism of the first stopper mechanism positions the first stopper portion on the intermediate frame -10-200934637 before the label is placed from the label take-up mechanism to the intermediate gantry. Further, the second advancing and retracting mechanism of the second stopper mechanism is such that the second stopper portion is positioned at the retracted position before the label is placed on the intermediate frame from the label take-up mechanism until the label abuts on the first stopper portion. The second stopper is positioned on the intermediate stage before the moment when the label abuts on the first stopper. As a result, the second stopper does not interfere when the label is placed on the intermediate frame. And the first stop can surely stop the label placed on the intermediate stand. In addition, the second stop can be used to prevent the label from moving in the opposite direction of the phase n, positioning the label in the correct position. Further, a pressing means for pressing the label to the intermediate frame to correct the label curl (warpage) may be provided. When the above-mentioned pressing means is provided, the curling (warpage) of the label can be corrected before the conveyance, and the winding accuracy of the label can be improved. Further, when the pressing means is provided, the first and second stopper means are configured to retract the first and second stoppers to the retracted position when the pressing means presses the label toward the intermediate frame. In this way, the label can be pressed even if the first and second stopper mechanisms are provided. Φ The label transport mechanism can maintain the determined label position (label position in the forward direction) by the label positioning mechanism, and the mechanism for transporting the label to the winding frame can be of any configuration. For example, the label transport mechanism may be a pair of clamps that grip both ends in the width direction orthogonal to the direction in which the label is oriented, and a slide mechanism that slides the pair of clamps between the first position corresponding to the intermediate stage and the second position of the corresponding winding frame And an operation control device that controls the operation of at least one pair of clamps and sliding mechanisms. The specific label transport mechanism constitutes an end edge holding and transporting device. At this time, the motion control device operates as follows. First, the pair of jigs are held at both ends in the width direction orthogonal to the direction in which the label positioned by the label positioning machine -11 - 200934637 is positioned. Then, the slide is slid from the first position to the second position, and then a pair of jigs are opened to place the label on the winding table. Next, an operation of sliding the pair of jigs from the second position to the first position is performed. When the label is held by a pair of jigs and the label is transported from the intermediate stage to the winding stand, the position (positional relationship) of the positioning state can be maintained, and the label can be conveyed without being bent or twisted. Therefore, there is no need to reposition the label with the winding stand, and no correction is required. The label take-up mechanism can be any take-out configuration. When the label hopper is disposed in such a manner that the label take-out opening in which one label is exposed is downward, the label take-out mechanism is disposed under the label take-out port by using the take-out structure, and one label is taken out from the label take-out port, and the label is sent out. The structure formed by the intermediate gantry can be used. Further, the label take-out mechanism at this time may be constituted by a suction device including a movable suction unit and a suction unit moving device disposed below the label take-out port, and a label dispensing device. The adsorption unit moves the adsorption unit between the adsorption position of the one label exposed from the label take-out port and the standby position of the adsorption position in the standby state. Further, in the process in which the label ejecting unit moves from the suction position to the standby position, the label ejecting unit sends out one of the labels ejected from the label take-out port toward the intermediate stage without restricting the label. With the above construction, the label take-up mechanism can be delicately arranged under the label hopper. As a result, a compact structure of the label supply device can be obtained at the same time. Further, the adsorption device can use a device in which two adsorption nozzles arranged at intervals are used as adsorption portions, and air is sucked from the two adsorption nozzles to produce an adsorption force of -12-200934637. Further, the adsorption device draws air from the adsorption nozzle to the operation range of the label delivery device while the adsorption unit is moving from the adsorption position to the standby position. Further, the adsorption portion moving means is configured to move the adsorption portion between the adsorption position and the standby position by the swing motion centering on the rotation center. According to the above configuration, the label can be taken out from the label hopper only by the swing operation of the adsorption nozzle, and the structure of the label take-up mechanism can be simplified. Φ Further, the label feeding device is provided with an endless belt that is disposed at an opposite position to the label take-out port, receives one sheet of the label taken from the label take-out port, and rotates in order to feed the label to the intermediate stage. It is better to carry the conveyor belt device. When the label feeding device of this configuration is used, the removed label can be smoothly sent out to the intermediate stage without requiring a large installation space. The present invention also provides a method of supplying a label to an insert molding system. The label supply method of the present invention is to take out a label from a label hopper containing a plurality of sheets of labels and place the label on the intermediate stage, and then carry the label on the intermediate stage to the winding of the label around the core. The gantry is wound around the periphery of the core-like core on the winding gantry, and is wound around the core-like core to supply the label to the injection molding die. Also, the position of the label is positioned at the correct position on the intermediate stand. And before or after the position of the label is positioned, the label is pushed to the curl (warping) of the intermediate stage correction label. Thereafter, the label is conveyed to the winding stand while maintaining the corrected state. [Effect of the Invention] -13- 200934637 According to the present invention, the "replenishment of the label can be performed in the operation of the insert molding system" to avoid a decrease in the production efficiency of the insert molding system. [Embodiment] Hereinafter, the present invention is applied to a preferred embodiment of insert molding according to the drawings.

Further, the drawings are diagrams for explanation, and for easy understanding, a part thereof is exaggerated and drawn, and the size ratio of each part is different from the actual size ratio. 1st, 2nd, and 3rd, the insert molding system 具备 includes an injection molding machine (embed molding machine) 2; and a label supply device 3 for supplying a label L to the fixed mold 21 provided in the insert molding machine 2; And a label take-out mechanism 50 that extracts one of the lowermost labels L from the label hopper 4 in which the plurality of sheet labels L are stacked, and a label L that takes out the label take-up mechanism 5 to the intermediate rack 13 and transport it to the label supply device 3 The label transport device 6 of the label transport mechanism 51. The insert molding machine 2 is formed by inserting a molded article 1 1 composed of a label L shown in Fig. 3 and a molded article 10 such as a synthetic resin cup or a truncated cone container in which the label L is integrated on the surface. use. As shown in Fig. 1, there is a fixed mold 21' mounted on a conventional fixed platen 20 and a movable mold 23 mounted on the movable platen 22, and the movable mold 23 is advanced and retracted toward the fixed mold 21 by the mold clamping mechanism 24. (Arrow-14 - 200934637 in Figure 1 Head XI, X2 direction). The fixed mold 21 has a frustoconical recess 21a that conforms to the outer surface of the molded workpiece 11 formed by a cup or a truncated cone or the like. The peripheral wall of the recess 21a, for example, a plurality of suction/supply passages (not shown) The suction and the air supply passages are connected to the air suction means and the air supply means (none of which are shown) by a switching valve (not shown). And the 'cut-cone recess 21a communicates with the injection mechanism 25» φ. The movable mold 23 has a truncated-conical core which protrudes from the inner surface of the insert-molded workpiece 11 formed by a cup or a truncated cone or the like at its front end. 26. A label conveying device 6 is provided on the side of the insert molding machine 2. The label supply device 3 includes: a mold core 30; a first holding arm 31 that mounts such a mold core 30 on a surface facing the fixed mold 21 on the front end side; an adsorption pad 32; and the adsorption pad 32 is mounted on the The second grip arm 33 on the opposite surface of the movable mold 23 on the distal end side is assembled with the first and second grip arms 31 and 33 so as to be movable in the directions of arrows XI and X2 and Y1 and Y2 第 in the first drawing. The molded product extracting machine 34 and the advancing and retracting device (not shown) that the first and second gripping arms 31 and 33 move forward and backward in the directions of the arrows XI and X2 and the Y1 and Y2 directions are assembled. The outer shape of the core-like core 30 is the same as the outer shape of the insert-molded workpiece molded article 11 (see FIG. 3), and a plurality of intake holes 30a are provided on the outer surface thereof, and each of the intake holes 30a is communicated via a switching valve (not shown). Suction means and air supply means (all not shown). Further, the adsorption pad 32 is connected to the air suction means and the air supply means (none of which are shown) via a switching valve (not shown). As shown in Fig. 1 and the second chart, the label hopper 4 is placed in a state in which the accommodating portion 41 of the plurality of sheet labels L is inclined in a state of being overlapped by -15-200934637. Further, the label hopper 4 has a label take-out port 4a at the lower end portion of the accommodating portion 41, and a label nip port 4b at the upper end portion. The label take-out port 4a naturally causes the label to not fall to support the lowermost label. The label hopper 4 of the present embodiment is disposed in the storage portion 8 in an inclined posture, and the label take-out port 4a is opposed to the label take-up mechanism 50 of the label transport device 6, so that the upper end opening of the label filling port 4b is made larger. The label take-out port 4a is retracted to the side opposite to the direction D. The label hopper 4 is stored in the storage portion 8 having the safety door 81. The storage portion 8 is composed of a security door 81 and a frame 82. The safety door 81 has a box shape with an open side. The frame 82 has a structure in which the label transporting device 6 is housed and the lower half of the label hopper 4 is housed. An opening portion 82A (Fig. 2) is formed at the rear end portion of the frame 82. The safety door 81 is attached to the frame 82 by a pair of hinge mechanisms 83 to close the opening portion 82A. The pair of hinge mechanisms 83 are disposed at intervals along the upper and lower sides extending in the vertical direction of the opening 82A, and the safety gate 81 and the frame 82 are coupled. As shown in Fig. 1, a pair of hinge mechanisms 83 are provided with a closing means 84 using a spring as a driving source. The closing means 84 opens the safety door 81 (see the two-dot virtual line of Fig. 2) in order to open the door opening force applied to the safety door 81 by the molding operator. Further, the closing means 84 constitutes that the safety door 81 is automatically closed by the restoring force of the compressed spring once the door opening force is released. Further, even if the system of the present embodiment is in a state in which the safety door 81 is opened, the operation of the label transporting device 6-16-200934637 including the label take-out mechanism 50 and the label transport mechanism 51 can be continued. Therefore, in order to replenish the label L to the label hopper 4, the molding worker can continue the operation of the label transporting device 6 including the label take-up mechanism 50 and the label transport mechanism 51 even if the security door 81' is opened, so that the production of the insert molding system 1 can be avoided. Reduced performance. Further, even if the closing operation of the label L is not performed, the door can be automatically closed by the door closing means 84 by the door closing means 84 to ensure safety even if the door opening operation is not released, i.e., the hand is separated from the safety door 81. Therefore, according to the state of the present embodiment, the molding worker does not suffer from the safety or negligence of the door closing operation. Further, when the fence is provided outside the system, the safety door 81 is not required. 〇 The structure of the label hopper 4 can be extracted from the label take-out port 4a. For example, Fig. 7 and Fig. 8 show that the concrete hopper 4 has a pair of side walls 4c and 4c and a bottom wall 4d that connects the pair of side walls 4c and 4c. The label hopper 4 is provided with an opening 4e at a portion opposed to the bottom wall 4d. Therefore, when looking at the label hopper 4 from above, as shown in Fig. 8, the label L can be seen. Further, the pair of side walls 4c, 4c are provided with a label support portion 4f which is in contact with the lowermost label L in the vicinity of the label take-out opening 4a and supports the label. Further, the inner wall portion ' of the pair of side walls 4c of the label hopper 4 is spaced apart from the label ejector opening 4a by a predetermined interval from the position close to the label ejector opening 4a, and a pair of fitting grooves opposed to each other by solid lines are provided. The 40° pair fitting groove 40 can be fitted into both end portions in the width direction of the partition plate 41 constituting the load weight limiting means by the opening portion 4e. As shown in Fig. 8, when the pair of fitting grooves 40 near the label take-out port 4a are fitted to the partition plate 41, the lowermost label L of the most -17-200934637 adjacent to the label take-out port 4a does not have the partition 41. The load of the weight of most of the labels L existing in the area between the label filling ports 4b. The lowermost label L can be easily separated and extracted. Therefore, it is possible to use the large (long-sized) label hopper 4 in which the number of sheets L is stacked. As a result, the number of times of the label L per unit time can be suppressed, and the burden on the molding worker can be reduced. When the partition 41 is provided. When the amount of the label under the partition 41 is reduced to some extent during the operation of the system, the partition 41 is removed, and the label L above the partition 41 is dropped to the lower side of the partition 41. And then, the spacer 41 is again fitted to the fitting groove 41. The actual separator 41 is a separator having a thin metal thickness. Therefore, even if the partition 41 is reinserted, it is particularly resistant. Further, when the amount of the label stored in the label hopper 4 is an appropriate amount or the weight of the label is used, the spacer 41 does not have to be used. Further, in the seventh and eighth figures, it may be represented by a two-dotted broken line, and a predetermined interval is formed at a predetermined interval in the longitudinal direction of the label hopper 4, and a fitting groove 40 is provided at a plurality of points, and a dotted line of two dots is indicated. The spacer 41 is detachably fitted into each of the fitting grooves 40 from the upper side. That is, a configuration using a plurality of partitions (load weight limiting means) 41 may be employed. At this time, when the label is replenished, it is only necessary to sequentially extract and reinsert from the partition 41 positioned below. Also, of course, the insertion and extraction of the spacer 41 can be automated. In the embodiment of the present invention, the label hopper 4 is disposed in a downward posture in which the label take-out port 4a in which one label is exposed is downward. Therefore, the label take-up mechanism 50 is disposed below the label take-out port 4a, and is configured to take the outlet 4a from the label. One piece of the label L (separate extraction) is taken out, and the label L is sent out to the intermediate frame 200934637. Further, the label transport mechanism 51 is used as a winding frame 14 for transporting the label placed on the intermediate stage 13 to the label supply unit 3. In the present embodiment, the label ejecting mechanism 51; the label transport mechanism 51; and the label positioning mechanism 7 that positions the label L taken out by the label take-out mechanism 50 at the correct position in the intermediate rack 13 to constitute the label Transport mechanism 6. In the label transport mechanism 51 of the present embodiment, both end edges in the width direction of the label L taken out from the lower portion of the label hopper 4 are sandwiched by the label extractor φ structure 50 (the both end edges in the arrow W direction of Fig. 1) In the part, the label L is transferred to the end edge portion holding and conveying device up to the delivery position of the mold core 30 (the winding frame 14 to be described later). As shown in FIG. 4 and FIG. 5 in detail, in the present embodiment, the label take-out mechanism 50 is disposed below the label take-out port 4a, and is an adsorption device 50A including a movable suction unit 52 and an adsorption unit moving unit 53, and The label delivery device 50B is configured. The stencil dispensing device 50B has a 铍 〇 〇 的 的 和 和 和 和 和 和 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 标签 的 的 的 的 的 的 的Two sets of endless belts (conveyor belts) 54, 55. The two sets of endless belts 54, 55 extending parallel to each other with an upward slope are spaced apart by a predetermined interval. The motive pulley 54a, the motive pulley 55a, the driven pulley 54b, and the driven pulley 55b of the endless belts 54, 55 are fixed to the rotating shaft 56 extending in the width direction (the direction of the arrow W in Fig. 5). The primary movable pulleys 54a and 55a are rotationally driven by an electric motor 56a (Fig. 5) based on a control signal from the control unit 12 via a digitally controllable servomotor or the like. The space between the endless belts 54, 55 of the two -19-200934637 group is provided with an adsorption device 52. The adsorption device 52 includes two adsorption nozzles 52a disposed at intervals, as the adsorption portion 52. The adsorption unit moving device 53 sucks the adsorption position of one label L exposed from the label take-out port 4a in the adsorption unit 52 (the position where the adsorption unit 52 is indicated by a solid line in Fig. 4) and the adsorption unit 52 is in the standby state. In the standby position (the position where the adsorption portion 52 is indicated by a broken line in Fig. 4), the adsorption portion 52 is swung around the center of rotation c. The adsorption device 52 draws air from the two adsorption nozzles 52a to the operation range of the label delivery device 5OB during the movement of the adsorption unit 52 from the adsorption position to the standby position. That is, the adsorption force generated by the suction of the two adsorption nozzles 52a combines the label L and the adsorption portion 52 of one sheet. When the adsorption unit 52 is rotated from the suction position to the standby position, the label L is taken out from the label hopper 4, and the suction of the air from the adsorption nozzle 53a is stopped before the label reaches the label delivery unit 50B. As a result, the label L is placed on the endless belts 54, 55 of the conveyance belt unit of the label dispensing unit 50B, and is fed to the intermediate stage 13 by the rotating endless belts 54, 55.

孔18a和18b的內部，使第2止動部19c、19d的前端部 退避到容許標籤通過的退避位置。 該例雖是使用銷狀的一對第1止動部19a、19b及一 對第2止動部19c、19d，但是該等止動部當然也可以分 別藉1個構件所構成。 本實施的形態中，第1止動機構7A使得一對第1止 動部19a、19b的前端部突出中間架台13的塊體部13a、 13b的表面，藉以阻止標籤取出機構50的標籤送出裝置 5 0B因慣性力使得送出到中間架台13上的標籤L在塊體 部13a ' 13b的表面上滑動而朝著捲繞架台14定位的進行 方向飛出。並且第2止動機構7B的一對第2止動部 19c、19d利用抵接在第1止動機構7A的一對第1止動部 19a、19b的標籤抵接時的反作用來阻止回到和進行方向D 相反的方向。 本實施形態中，第1止動機構7A的第1進退機構 19B將從標籤取出機構50所送出的標籤L放置在中間架 台13的塊體部13a、13b上之前，將第1止動部19a、 19b的前端部定位在中間架台13上。又第2止動機構7B 的第2進退機構19B將標籤L從標籤取出機構50送出到 中間架台13的塊體部13a、13b之後，到標籤L抵接在第 1止動部19a、19b的瞬間爲止預先將第2止動部19c、 -22- 200934637 19d定位在退避位置，到標籤L抵接在第1止動部19a、 19b的瞬間前使第2止動部19c、19d的前端部位在中間 架台13上。其結果，第2止動機構7B在標籤L放置在 中間架台13的塊體部13a、13b上時不會造成阻礙。並且 可以第1止動部19a、19b確實停止放置在中間架台13上 的標籤L。另藉著第2止動部19c、19d可以確實阻止朝 著相反方向的移動，將標籤定位在正確的位置上。 φ 如上述標籤定位機構7是在第1止動機構7A的一對 第1止動部19a、19b和第2止動機構7B的一對第2止動 部19c、19d之間夾持著標籤，決定使標籤L位置形成正 確的位置（正確姿勢）。即使得一對第1止動部19a、19b 和一對第2止動部19c、19d之間的間隔尺寸Lx與沿著標 籤L的進行方向D所測得的尺寸實質上一致，藉此可進 行標籤的定位。再者，該實施形態中，中間架台1 3構成 可分離爲兩個塊體13a及13b，第1止動機構7A構成可 〇 和塊體13b —起移動。因此，根據本實施形態，因應標籤 形狀的不同，可以移動塊體13b變更上述的間隔Lx。並 且使塊體13a和塊體13b分離變更間隔Lx的場合，只要 在其間所形成間隙內嵌入另外準備的輔助塊體消除間隙即 可。 如第1圖、第4圖至第6圖表示，本實施形態的標籤 搬運機構51，係由：把持著和標籤L的進行方向D正交 的寬度方向W兩端的一對夾具59;使一對夾具59滑動的 一對汽缸裝置57所成的滑動機構；及控制裝置12所構 -23- 200934637 成。一對夾具59分別可動作地被安裝在朝著直線方向延 伸的臂部58的一端。臂部58的另一端被固定在水平方向 延長收縮的一對汽缸裝置57的活塞桿57a的前端。構成 滑動機構的一對汽缸裝置57使得一對夾具59在對應中間 架台13的第1位置P1 (第1圖及第5圖）和對應捲繞架台 14的第2位置P2(第1圖及第2圖）之間滑動。一對汽缸 裝置57是位在一對環形皮帶54、55的寬度方向（第5圖 的箭頭W方向）兩側的上方位置。如第5圖表示，一對汽 缸裝置57是相對於一對環形皮帶54、55平行配置。一對 汽缸裝置57的各前室是經由送·排氣管18a連通到電磁 轉換閥12的第1埠12a，各個後室則是經送·排氣管1 8b 連通到電磁轉換閥12的第2埠12b。並且，電磁轉換閥 12的供氣埠12c是經由供氣管18c連通於空氣壓縮機等 的高壓空氣供給源17。電磁轉換閥12是根據來自控制裝 置12的控制訊號切換，將高壓空氣供給各汽缸裝置57的 前室或後室使汽缸桿57a進退。並且，EX是表示排氣 淳。 根據控制裝置1 2的動作控制，首先，以一對夾具5 9 把持著和標籤定位機構7所定位標籤L的進行方向D正 交的寬度方向W的兩端。之後使汽缸裝置57動作，讓一 對夾具59從第丨位置1»1滑動到第2位置P2。接著打開 一對夾具57將標籤L放置在捲繞架台14上。並使得汽缸 裝置57動作，進行一對夾具59從第2位置P2滑動到第 1位置P1的動作。如本實施形態，以一對夾具5 9把持著 -24- 200934637 標籤L的兩端將標籤L從中間架台13搬運到捲繞架台14 時，維持著標籤定位機構17所定位的姿勢（位置關係）， 不致使標籤彎曲或扭轉可進行搬運。因此不需要以捲繞架 台14進行標籤L的再次定位或矯正。 如本實施形態所記載，在標籤取出機構50和標籤搬 運機構51之間設有放置標籤的中間架台13時，標籤取出 機構50的構造及標籤搬運機構51的構造可以是任意的構 φ 造。因此可以提高標籤供給機2的設計自由度。 接著，上述實施形態的系統中，針對標籤搬運到捲繞 架台14上之後的動作說明如下。標籤L載放在捲繞架台 14的預定位置的時刻，標籤供給裝置3的第1把持臂31 和類模芯30及第2把持臂33和吸附部32是在實線表示 的待機位置P3待機。在此，藉著成型品取出機34的未圖 示的進退裝置將第1把持臂31朝箭頭XI方向移動，使 類模芯30抵接或接近捲繞架台14上的標籤L的寬度方向 . 中央部。 接著，從類模芯30的多數個吸氣孔30a吸氣。藉以 使類模芯30周邊部的空氣產生朝著吸氣孔30a的空氣流 動。藉著該空氣的流動標籤L從抵接類模芯30外圍一部 份的寬度方向中央部跨寬度方向的兩端緣部依序朝著類模 芯30的外圍被吸引後彎曲，最終捲繞在類模芯30的外圍 上。接著，以未圖示的進退裝置朝箭頭X2方向移動第1 把持臂3 1，回到實線表示的待機位置P3。 接著，以未圖示的進退裝置使第1把持臂31和類模 -25- 200934637 芯30及第2把持臂33和吸附部32前進到P4位置。在此 時刻嵌入成型機2的固定模具21和活動模具23已開啓。 因此，第1把持臂31及第2把持臂33進入開啓的模具 21、23間，使類模芯30與固定模具21的截錐形凹部21a 對向的同時，各吸附部32在上述開模的前段形成而和外 嵌保持在活動模具23的模芯26的嵌入成型工件成型品 1 1(參閱第3圖）對向。 其次，藉未圖示的進退裝置使第1把持臂31朝著固 定模具21的方向（第1圖的箭頭XI方向）前進，將類模芯 30***到固定模具21的截錐形凹部21a停止。在此，解 除類模芯30產生對標籤L的吸氣而切換成送氣，同時使 固定模具21側的未圖示的吸•送氣通路負壓化，將標籤 L吸附保持在截錐形凹部21a的內面。亦即，標籤L從類 模芯分離被安裝在截錐形凹部21a內。 另一方面，以未圖示的進退裝置使第2把持臂33朝 著活動模具23存在的方向（第1圖的箭頭X2方向）前進。 將第2把持臂33停止在吸附部32抵接或接近以嵌入活動 模具23的模芯26的狀態所保持之嵌入成型工件成型品 1 1(參閱第3圖）底部的位置。在此，藉吸氣使得吸附部32 負壓化並在吸附部3 2吸附保持著嵌入成型工件成型品1 1 的底部。藉此，將嵌入成型工件成型品11從活動模具23 的模芯26交接到吸附部32。 如上述，從類模芯30對截錐形凹部21a之標籤L的 交接結束時，以未圖示的進退機構使第1把持臂31回到 -26- 200934637 P4位置的實線表示的位置。並從活動模具23的模芯26 對吸附部32之嵌入成型工件成型品11的交接結束時，以 未圖示的進退機構使第2把持臂33回到P4位置的實線表 示的位置。 接著，以未圖示的進退機構使第1把持臂31及第2 把持臂33後退到P3位置爲止。在此，解除吸附部32的 吸氣來解放嵌入成型工件成型品11。解放後的成型品11 爲輸送帶等搬運手段（省略圖示）所接收加以適當回收。 第1把持臂31及第2把持臂33後退到P3位置爲止 的期間，藉著合模機構24使活動模具23朝著固定模具 21前進。並且，使兩模具21、23合模將活動模具23的 模芯26***固定模具21的截錐形凹部21a。其結果，形 成模芯26的外面、截錐形凹部21a的內面、標籤L的內 面及活動模具23的前端面所圍繞的嵌入成型工件成型品 11成型用的空腔（省略圖示）。在此狀態下，從射出機構 25射出熔融樹脂塡充到上述未圖示的空腔內。 塡充到空腔內的熔融樹脂是以預定時間核模的狀態保 持著，因此和標籤L的內面側持續熔合形成一體化凝固。 藉以成型爲標籤L及將此標籤L 一體化的合成樹脂製的 杯子或截錐形容器等成型品1〇所成的嵌入成型工件成型 品11(參閱第3圖）。在此，解除因固定模具21側的未圖 示之吸•送氣通路的吸氣所致的負壓化。再者，反覆上述 的動作，可以連續製造嵌入成型工件的成型品。 上述的實施形態中，利用吸氣將標籤L安裝在固定模 -27- 200934637 具21的凹部21a的內周圍。但是對於利用靜電吸附力將 標籤安裝在固定模具21的凹部21a內周圍的習知的射出 成型機，當然同樣可運用本發明。利用靜電吸附力將標籤 安裝在固定模具21的凹部21a內周圍的場合，只要如第 9圖所示構成標籤供給裝置3即可。靜電帶電裝置1〇〇具 備帶電用電極1〇1、高電壓產生器102及選擇手段103。 類模芯30是使用具導電性的模芯。在標籤L捲繞在類模 芯30的捲繞架台14附近，以具有導電性的類模芯30爲 一方的帶電用電極’配置標籤L帶有靜電之靜電帶電裝置 100的另一方的帶電用電極101。 捲繞架台14配置如第1〇圖表示的板1〇4。該板104 收容著提高標籤L的棒型的一對活動構件1〇5。一對活動 構件105是如第10圖表示，非動作時是位在比接觸面 106後退的第1位置P5，動作時從第1位置P5越過接觸 面106移動到接近類模芯30的第2位置P6。未圖示的活 動構件驅動裝置，使得2個活動構件105與吸引裝置的標 籤L對類模芯30的捲繞動作同步從第1位置P5移動至第 2位置P6，捲繞動作結束時，使2個活動構件105動作從 第2位置P6回到第1位置P5。並且，2個活動構件105 位於第2位置P6時，決定2個活動構件105之間的距離 將類模芯30定位在2個活動構件105之間。因此，形成 2個活動構件105朝著類模芯推高標籤L。藉著該2個活 動構件105推高標籤L，通過設置在類模芯30的周圍壁 部3 0b的複數個吸氣孔3 0a，以自類模芯30內部吸氣產 200934637 生的吸引力，有助於標籤吸附在類模芯30外圍面的吸附 作業。其結果，可促進對類模芯30進行標籤L吸附作業 之速度的提升。 另外也可以在第1〇圖以虛線表示的帶電用電極101， 的位置配置帶電用電極。第10圖以虛線表示的帶電用電 極101’的位置配置帶電用電極的場合，也可預先以防止 靜電帶電的材料形成板104。此外，以類模芯30作爲放 φ 電用的—方電極的場合，從高電壓產生器102產生的高壓 電的峰値與脈衝寬度可根據標籤L的形狀及類模芯30的 形狀適當加以決定。並且一般電壓的峰値多數是在 20~30kV的範圍。 靜電帶電裝置100是根據來自選擇手段103的選擇操 作’形成動作狀態或非動作狀態。使用以上的靜電帶電裝 置100時’運用標籤供給機3的射出成型機利用靜電吸附 力將標籤L吸附在模具內周圍面的場合或不吸附的場合皆 Q 可供給標籤。並且爲了防止板104的帶電，也可以防止靜 電帶電的材料形成板104。 採用以上的構成時，捲繞架台14中標籤L捲繞在類 模芯30時，可賦予標籤l帶電電荷。因此不需要在捲繞 架台14和模具21、23之間設置大的帶電裝置。又對類模 芯30之標籤l的吸附，也可利用靜電吸附力，以獲得標 籤捲繞作業之速度的提升。 再者’標籤供給裝置3本質上的功能並非經常須大致 胃時進行吸氣之標籤的捲繞和使標籤的帶電，當然也可以 -29- 200934637 在根據吸氣標籤對類模芯30上的捲繞結束之後，進行標 籤的帶電。當然是利用靜電吸附力的場合的標籤必須以具 有可帶電的合成樹脂材料等的絕緣性材料形成。 第11圖是表示本發明其他實施形態主要部的構成 圖。該實施形態中，更具備將標籤L推壓至中間架台13 的塊體部13a、13b矯正標籤L的捲邊（翹曲）的壓緊手段 107，以汽缸將壓板108朝著塊體部13a、13b下壓，在壓 板108和塊體部13a、13b之間壓緊標籤。預先設置上述 A 的壓緊手段107，搬運前可以矯正標籤的捲邊（翹曲），可 提高標籤的捲繞精度。並且該實施形態中，第1及第2止 動機構7A及7B根據壓緊手段107移動的壓板108將標 籤朝著中間架台13推壓時，使第1及第 2止動部 19a〜19d退避到退避位置。因此藉著第1及第2止動機構 7A及7B，在標籤L定位後的狀態下，不會移動標籤L可 壓緊標籤L。因此不會使標籤的定位精度降低。 再者，壓緊手段107進行的壓緊步驟也可以藉著標籤 @ 定位機構7決定標籤的位置之後，或者正確決定標籤位置 之前的其中之一實施。正確決定標籤的位置之前也實施壓 緊的場合，藉著第1止動機構7A停止標籤之後，使第1 止動機構7A的第1止動部退避後，實施壓緊手段1〇7的 壓緊。藉壓緊手段107先實施壓緊的場合，是在壓緊之後 再度使第1及第2止動機構7A及7B動作進行標籤的定 位。 上述的實施形態中，標籤雖大致呈弧形，但是標籤的 -30- 200934637 形狀不僅限於上述實施形態的標籤的形狀。例如，第12 圖是表不將黏貼在細長箱外面的標籤L’的一例定位在標 籤定位機構7的第1及第2止動部19a〜19d，藉著標籤搬 運機構的一對夾具59把持著位在標籤L’寬度方向的端部 的狀態。第12圖中’夾具是以虛線表示。並且以夾具59 把持標截L’ 一部分的場合’也可在符號59’表示的位置把 持標籤L’。以上的場合，只要改變一對汽缸裝置57的啓 φ 動位置即可。 又上述實施形態使用的類模芯30，吸附標籤L的周 圍壁部30b的外圍面具有截錐面形狀。因此，由於形成在 類模芯30的複數個吸氣孔2b的位置，或吸附前標籤和類 模芯3 0的位置關係的偏移，使得標籤不能被吸附在類模 芯30上的正確位置’而多少會產生偏移。如此的偏移， 可藉著類模芯30加工精度的提升、上述標籤定位精度的 提升加以消除。但是，期待即使不提升類模芯的加工精 φ 度，或者提升標籤定位精度所需以上的精度，仍可將標籤 吸附在類模芯外圍面的正確位置的技術。在實現以上的期 待’只要使用13(A)圖及（B)表示的類模芯30,即可。並且 第13(A)圖的剖面圖雖圖示著標籤，但是未圖示通氣孔。 該類模芯30’中’捲繞標籤l的區域R1形成比其他區域 (未捲繞標籤的區域）R2更朝著類模芯30,的中心部Co側 下陷的凹部。亦即’只要使捲繞標籤L的區域下陷，在其 凹陷捲繞標籤即可。從另外角度來看，是形成藉區域R1 形成標籤捲繞用的定位部。採用此一構成，藉著吸氣將標 -31 - 200934637 籤吸附在類模芯時，標籤進入到凹部’可藉此進行標籤對 類模芯的定位。 【圖式簡單說明】 第1圖是表示本發明一實施形態的槪略上視圖。 第2圖爲第1圖的Π-Π箭頭視圖。 第3圖是表示嵌入成形工件成型品之一例的放大縱剖 視圖。 第4圖是表示標籤搬運裝置之一實施形態的放大側視 圖。 第5圖是省略標籤料斗顯示之第4圖的上視圖。 第6圖爲說明標籤搬運機構的一對夾具和標籤的關係 所使用的圖。

L X :間隔 P1 :第1位置 P 2 :第2位置 P3 :待機位置In the embodiment of the present invention, the label feeding device 50B conveys the label using the conveyance belt device, and conveys one label extracted from the label take-out port 4a to the intermediate frame 13 without being restrained. With the above configuration, a small label take-out mechanism 50 can be disposed below the label hopper. Further, the structure of the label take-up mechanism 50 can be simplified by simply rotating the suction nozzle 52a and taking out the label from the label hopper. Further, when the label feeding device 50B 200934637 formed by the conveyance belt device is used, the taken-out label can be smoothly sent to the intermediate stage 13 by the inertial force without requiring a large installation space. As shown in Fig. 4 and Fig. 5, the intermediate stage 13 (first stage) 13 is made of a metal plate having a smooth surface. The width direction dimension of the intermediate stage 13 (the dimension in the arrow direction of Fig. 5) is set smaller than the width direction dimension of the label L. The intermediate stage 13 is provided with a gantry portion formed by two blocks 13a and 13b and a label positioning mechanism 7. The two blocks 13a and 13b have a structure in which the surface is flat and slid. Further, the two blocks 13a and 13b are formed with four through holes 18a to 18d extending in the thickness direction of the blocks 13a and 13b. In Fig. 2, illustration of the through holes 18a to 18d provided in the block portions 13a and 13b is omitted. The block portions 13a, 13b determine that their configuration does not cause a large step or a large gap between the endless belts 54, 55 of the conveying conveyor device. The label positioning mechanism 7 of the present embodiment includes a first stopper mechanism 7A and a second stopper mechanism 7B. The first stopper mechanism 7A includes a pair of pin-shaped first stopper portions 19a and 19b that abut against the front end edge of the label L, and a first advance/retraction mechanism 19A. The first advancing and retracting mechanism 19A protrudes from the through holes 18a and 18b (Fig. 5) only when the stopper function is exerted, and the distal end portions of the pair of first stopper portions 19a and 19b are located on the intermediate frame 13. When the first advance/retract mechanism 19A does not need to exhibit the stop function, the pair of first stoppers 19a and 19b are pulled into the inside of the through holes 18a and 18b, and the distal ends of the first stoppers 19a and 19b are retracted. Go to the retreat position where the label is allowed to pass. The second stopper mechanism 7B includes a pair of pin-shaped second stopper portions 19c and 19d and a first advancing and retracting mechanism 19B which are in contact with the rear end edge of the label L. The second advancing and retracting mechanism 19B protrudes from the through holes 18c and 18d (Fig. 3) at the distal end portions of the pair of second stopper portions 19c and 19d-21-200934637 only when the stopper function is exerted, and the distal end portion thereof is located at the intermediate frame 13 on. When the second advance/retract mechanism 19B does not need to exhibit the stop function, the pair of second stopper portions 19c and 19d are pulled into the through holes 18a and 18b, and the distal ends of the second stopper portions 19c and 19d are retracted. Go to the retreat position where the label is allowed to pass. In this example, a pair of pin-shaped first stopper portions 19a and 19b and a pair of second stopper portions 19c and 19d are used. However, these stopper portions may of course be constituted by one member. In the embodiment of the present embodiment, the first stopper mechanism 7A causes the front end portions of the pair of first stopper portions 19a and 19b to protrude from the surfaces of the block portions 13a and 13b of the intermediate frame 13, thereby preventing the label ejecting mechanism 50 from being ejected by the label ejecting mechanism 50. The 0B is caused by the inertial force so that the label L fed to the intermediate stage 13 slides on the surface of the block portion 13a' 13b and flies in the direction in which the winding frame 14 is positioned. Further, the pair of second stopper portions 19c and 19d of the second stopper mechanism 7B are prevented from coming back by the reaction of the abutting of the labels of the pair of first stopper portions 19a and 19b of the first stopper mechanism 7A. The direction opposite to the direction D. In the first embodiment, the first advancing and retracting mechanism 19B of the first stopper mechanism 7A places the first stopper 19a before placing the label L sent from the label taking-out mechanism 50 on the block portions 13a and 13b of the intermediate frame 13. The front end portion of 19b is positioned on the intermediate stage 13. Further, the second advancing and retracting mechanism 19B of the second stopper mechanism 7B sends the label L from the label taking-out mechanism 50 to the block portions 13a and 13b of the intermediate frame 13, and then the label L abuts on the first stopper portions 19a and 19b. The second stopper portions 19c and -22-200934637 19d are positioned at the retracted position in advance, and the distal end portions of the second stopper portions 19c and 19d are brought before the moment when the label L comes into contact with the first stopper portions 19a and 19b. On the intermediate stand 13 As a result, the second stopper mechanism 7B does not cause an obstruction when the label L is placed on the block portions 13a and 13b of the intermediate stage 13. Further, the first stopper portions 19a and 19b can surely stop the label L placed on the intermediate stage 13. Further, by the second stopper portions 19c, 19d, it is possible to surely prevent the movement in the opposite direction and position the label at the correct position. φ is such that the label positioning mechanism 7 holds the label between the pair of first stopper portions 19a and 19b of the first stopper mechanism 7A and the pair of second stopper portions 19c and 19d of the second stopper mechanism 7B. , decided to position the label L to the correct position (correct posture). That is, the interval dimension Lx between the pair of first stopper portions 19a and 19b and the pair of second stopper portions 19c and 19d substantially coincides with the dimension measured along the direction D of the label L, whereby Position the label. Further, in this embodiment, the intermediate stage 13 is configured to be separable into two blocks 13a and 13b, and the first stopper mechanism 7A constitutes a movable portion and a block 13b. Therefore, according to the present embodiment, the above-described interval Lx can be changed by moving the block 13b depending on the shape of the label. Further, when the block 13a and the block 13b are separated and changed by the interval Lx, a separately prepared auxiliary block eliminating gap may be embedded in the gap formed therebetween. As shown in Fig. 1 and Fig. 4 to Fig. 6, the label transport mechanism 51 of the present embodiment holds a pair of jigs 59 at both ends in the width direction W orthogonal to the direction D of the label L; A sliding mechanism formed by a pair of cylinder devices 57 that slides the clamp 59; and a control device 12 constructed as -23-200934637. A pair of jigs 59 are operatively attached to one end of the arm portion 58 extending in the linear direction. The other end of the arm portion 58 is fixed to the front end of the piston rod 57a of the pair of cylinder devices 57 which are extended and contracted in the horizontal direction. The pair of cylinder devices 57 constituting the slide mechanism have the pair of jigs 59 at the first position P1 (the first and fifth figures) corresponding to the intermediate frame 13 and the second position P2 of the corresponding winding frame 14 (the first figure and the 2)) slide between. The pair of cylinder devices 57 are positioned above the both sides of the pair of endless belts 54, 55 in the width direction (the direction of the arrow W in Fig. 5). As shown in Fig. 5, the pair of cylinder devices 57 are arranged in parallel with respect to the pair of endless belts 54, 55. Each of the front chambers of the pair of cylinder devices 57 is connected to the first port 12a of the electromagnetic switching valve 12 via the delivery/exhaust pipe 18a, and each of the rear chambers is connected to the electromagnetic switching valve 12 via the delivery/exhaust pipe 18b. 2埠12b. Further, the air supply port 12c of the electromagnetic switching valve 12 is connected to a high-pressure air supply source 17 such as an air compressor via the air supply pipe 18c. The electromagnetic switching valve 12 supplies high-pressure air to the front or rear chamber of each cylinder device 57 to advance and retreat the cylinder rod 57a in accordance with the control signal switching from the control unit 12. Also, EX is the exhaust enthalpy. According to the operation control of the control device 12, first, both ends of the width direction W orthogonal to the traveling direction D of the label L positioned by the label positioning mechanism 7 are held by the pair of jigs 5 9 . Thereafter, the cylinder device 57 is operated to slide the pair of jigs 59 from the first position 1»1 to the second position P2. Next, a pair of jigs 57 are opened to place the label L on the winding stand 14. The cylinder device 57 is operated to perform an operation of sliding the pair of jigs 59 from the second position P2 to the first position P1. In the present embodiment, when both ends of the -24-200934637 label L are held by the pair of jigs 59, the label L is transported from the intermediate stage 13 to the winding stand 14, and the position (positional relationship) at which the label positioning mechanism 17 is positioned is maintained. ), the label can be handled without bending or twisting the label. Therefore, it is not necessary to perform repositioning or correction of the label L by the winding stand 14. As described in the present embodiment, when the intermediate frame 13 on which the label is placed is provided between the label take-out mechanism 50 and the label transport mechanism 51, the structure of the label take-up mechanism 50 and the structure of the label transport mechanism 51 may be of any configuration. Therefore, the design freedom of the label feeder 2 can be improved. Next, in the system of the above embodiment, the operation after the label is transported to the winding frame 14 will be described below. When the label L is placed at a predetermined position of the winding frame 14, the first grip arm 31, the core-like core 30, the second grip arm 33, and the adsorption portion 32 of the label supply device 3 stand by at the standby position P3 indicated by the solid line. . Here, the first grip arm 31 is moved in the direction of the arrow XI by the advance/retract device (not shown) of the molded product extractor 34, so that the mold core 30 abuts or approaches the width direction of the label L on the winding frame 14. Central Department. Next, the air is sucked from the plurality of intake holes 30a of the core-like core 30. Thereby, the air at the peripheral portion of the core-like core 30 is caused to flow toward the air of the suction hole 30a. By the flow label L of the air, the both end edges of the center portion in the width direction of the peripheral portion of the abutting mold core 30 are sequentially attracted toward the outer periphery of the mold core 30 and then bent. On the periphery of the mold core 30. Next, the first grip arm 3 1 is moved in the direction of the arrow X2 by an advance/retract device (not shown) to return to the standby position P3 indicated by the solid line. Next, the first grip arm 31, the mold-type 25-200934637 core 30, the second grip arm 33, and the suction portion 32 are advanced to the P4 position by an advance/retract device (not shown). At this time, the fixed mold 21 and the movable mold 23 of the insert molding machine 2 are opened. Therefore, the first grip arm 31 and the second grip arm 33 enter between the open molds 21 and 23, and the mold core 30 is opposed to the frustoconical concave portion 21a of the fixed mold 21, and the adsorption portions 32 are opened at the same time. The front stage is formed to oppose the insert molded workpiece molded product 1 1 (see Fig. 3) which is externally held by the core 26 of the movable mold 23. Then, the first grip arm 31 is advanced in the direction of the fixed mold 21 (the direction of the arrow XI in the first drawing) by the advance/retract device (not shown), and the mold core 30 is inserted into the frustoconical recess 21a of the fixed mold 21 to stop. . When the mold core 30 is released, the suction of the label L is switched to the air supply, and the suction/supply passage (not shown) on the side of the fixed mold 21 is negatively pressurized, and the label L is adsorbed and held in the frustoconical recess 21a. Inside. That is, the label L is mounted in the frustoconical recess 21a from the core of the mold. On the other hand, the second grip arm 33 is advanced in the direction in which the movable mold 23 exists (the direction of the arrow X2 in Fig. 1) by an advance/retract device (not shown). The second grip arm 33 is stopped at a position where the suction portion 32 abuts or approaches the bottom of the molded workpiece molded product 1 1 (see Fig. 3) held in a state of being fitted into the core 26 of the movable mold 23. Here, the suction portion 32 is negatively pressurized by the suction, and the bottom portion of the insert molded workpiece 1 1 is adsorbed and held by the adsorption portion 32. Thereby, the insert molded workpiece molded article 11 is transferred from the mold core 26 of the movable mold 23 to the adsorption portion 32. As described above, when the transfer of the label L to the frustoconical recess 21a is completed by the mold core 30, the first grip arm 31 is returned to the position indicated by the solid line at the position -26-200934637 P4 by the advance/retract mechanism (not shown). When the transfer of the insert molded workpiece 11 to the suction unit 32 is completed from the core 26 of the movable mold 23, the second grip arm 33 is returned to the position indicated by the solid line at the position P4 by an advance/retract mechanism (not shown). Next, the first grip arm 31 and the second grip arm 33 are retracted to the position P3 by an advance/retract mechanism (not shown). Here, the suction of the adsorption unit 32 is released to release the molded workpiece 11 which is embedded. The molded article 11 after liberation is appropriately collected and collected by a conveying means (not shown) such as a conveyor belt. While the first grip arm 31 and the second grip arm 33 are retracted to the position P3, the movable mold 23 is advanced toward the fixed mold 21 by the mold clamping mechanism 24. Further, the two molds 21, 23 are clamped to insert the core 26 of the movable mold 23 into the frustoconical recess 21a of the fixed mold 21. As a result, a cavity for forming the molded workpiece 11 to be molded around the outer surface of the core 26, the inner surface of the truncated conical recess 21a, the inner surface of the label L, and the front end surface of the movable mold 23 (not shown) is formed. . In this state, the molten resin is injected from the injection mechanism 25 into the cavity (not shown). The molten resin which is filled into the cavity is held in a state of being subjected to the nucleation for a predetermined period of time, so that the inner surface side of the label L is continuously fused to form an integrated solidification. The insert molded workpiece 11 is formed by molding a molded article such as a label L and a synthetic resin cup or a truncated cone container in which the label L is integrated (see Fig. 3). Here, the negative pressure due to the suction of the suction/supply passage (not shown) on the fixed mold 21 side is released. Further, by repeating the above operation, the molded article in which the molded workpiece is embedded can be continuously manufactured. In the above embodiment, the label L is attached to the inner periphery of the concave portion 21a of the fixed mold -27-200934637 by the suction. However, it is a matter of course that the present invention can be applied to a conventional injection molding machine in which a label is attached to the periphery of the concave portion 21a of the fixed mold 21 by electrostatic attraction. When the label is attached to the periphery of the concave portion 21a of the fixed mold 21 by electrostatic attraction, the label supply device 3 may be constructed as shown in Fig. 9. The electrostatic charging device 1 includes an electrode for charging 1, a high voltage generator 102, and a selection means 103. The core-like core 30 is a core having conductivity. In the vicinity of the winding stand 14 in which the label L is wound around the mold core 30, and the charging type electrode 30 having one of the conductive cores 30 is disposed, the other charging of the electrostatic charging device 100 with the label L is performed. Electrode 101. The winding stand 14 is provided with a plate 1〇4 as shown in Fig. 1 . The plate 104 houses a pair of movable members 1〇5 of a bar type that raises the label L. The pair of movable members 105 are shown in FIG. 10, and are moved to the first position P5 that is retracted from the contact surface 106 during the non-operation, and moved from the first position P5 to the second surface of the proximity core 30 from the first position P5 during the operation. Position P6. In the movable member driving device (not shown), the two movable members 105 are moved from the first position P5 to the second position P6 in synchronization with the winding operation of the label L of the suction device with respect to the mold core 30, and when the winding operation is completed, The two movable members 105 are moved from the second position P6 to the first position P5. Further, when the two movable members 105 are located at the second position P6, the distance between the two movable members 105 is determined. The mold core 30 is positioned between the two movable members 105. Therefore, the two movable members 105 are formed to push the label L toward the core of the mold. By the two movable members 105, the label L is pushed up, and the plurality of suction holes 30a provided in the peripheral wall portion 30b of the core-like core 30 absorbs the attraction of the original mold core 30. It helps the label to be adsorbed on the peripheral surface of the mold core 30. As a result, the speed of the label L adsorption operation of the core-like core 30 can be promoted. Further, the charging electrode may be disposed at a position of the charging electrode 101 indicated by a broken line in the first drawing. In the case where the charging electrode is disposed at the position of the charging electrode 101' indicated by a broken line in Fig. 10, the plate 104 may be formed in advance with a material for preventing electrostatic charging. Further, in the case where the mold core 30 is used as a square electrode for φ electric power, the peak value and pulse width of the high voltage generated from the high voltage generator 102 can be appropriately selected according to the shape of the label L and the shape of the mold core 30. Decide. And the peak value of the general voltage is mostly in the range of 20~30kV. The electrostatic charging device 100 is formed in an operating state or a non-operating state in accordance with a selection operation from the selecting means 103. When the above-described electrostatic charging device 100 is used, the label can be supplied by the injection molding machine using the label feeder 3 when the label L is adsorbed on the peripheral surface of the mold by electrostatic attraction or when it is not adsorbed. Also, in order to prevent charging of the board 104, it is also possible to prevent the statically charged material from forming the board 104. According to the above configuration, when the label L is wound around the core 30 in the winding stand 14, the label 1 can be charged. Therefore, it is not necessary to provide a large charging device between the winding stand 14 and the dies 21, 23. Further, for the adsorption of the label 1 of the mold core 30, the electrostatic adsorption force can also be utilized to obtain an increase in the speed of the label winding operation. Furthermore, the intrinsic function of the label supply device 3 is not that the labeling of the inhaled label and the charging of the label are often required in the case of the stomach. Of course, it can also be used on the analog core 30 according to the inhalation label. After the winding is completed, the label is charged. Of course, the label in the case where the electrostatic adsorption force is used must be formed of an insulating material having a chargeable synthetic resin material or the like. Figure 11 is a block diagram showing the main part of another embodiment of the present invention. In this embodiment, the pressing means 107 for correcting the curl (warpage) of the label L by pressing the label L to the block portions 13a and 13b of the intermediate frame 13 is further provided, and the pressing plate 108 is directed toward the block portion 13a by the cylinder. And 13b is pressed down, and the label is pressed between the pressure plate 108 and the block portions 13a, 13b. The pressing means 107 of the above A is provided in advance, and the curling (warpage) of the label can be corrected before the conveyance, and the winding accuracy of the label can be improved. Further, in this embodiment, when the first and second stopper mechanisms 7A and 7B press the label toward the intermediate frame 13 by the pressure plate 108 that is moved by the pressing means 107, the first and second stopper portions 19a to 19d are retracted. Go to the retreat position. Therefore, with the first and second stopper mechanisms 7A and 7B, the label L can be pressed without moving the label L in the state in which the label L is positioned. Therefore, the positioning accuracy of the label is not lowered. Further, the pressing step by the pressing means 107 may be carried out by the labeling @positioning mechanism 7 after determining the position of the label or by correctly determining one of the positions of the label. When the pressing is performed before the position of the label is correctly determined, after the first stopper mechanism 7A stops the label, the first stopper of the first stopper mechanism 7A is retracted, and then the pressure of the pressing means 1〇7 is performed. tight. When the pressing means 107 is first pressed, the first and second stopper mechanisms 7A and 7B are operated again after the pressing, and the label is positioned. In the above embodiment, the label is substantially curved, but the shape of the label -30-200934637 is not limited to the shape of the label of the above embodiment. For example, Fig. 12 shows an example in which the label L' adhered to the outside of the elongated case is positioned on the first and second stopper portions 19a to 19d of the label positioning mechanism 7, and is held by a pair of jigs 59 of the label transport mechanism. The state of the end in the width direction of the label L' is placed. In Fig. 12, the jig is indicated by a broken line. Further, in the case where the gripper 59 holds a part of the mark L', the label L' can be held at the position indicated by the symbol 59'. In the above case, it is only necessary to change the position of the opening of the pair of cylinder devices 57. Further, in the core-like core 30 used in the above embodiment, the peripheral surface of the peripheral wall portion 30b of the adsorption label L has a truncated cone shape. Therefore, due to the position of the plurality of suction holes 2b formed in the core-like core 30, or the positional relationship between the label and the core-like core 30 before the adsorption, the label cannot be adsorbed to the correct position on the mold core 30. 'How much will produce an offset. Such an offset can be eliminated by the improvement of the machining accuracy of the core-like core 30 and the improvement of the positioning accuracy of the above-mentioned label. However, it is expected that the technique of adsorbing the label to the correct position of the peripheral surface of the core-like core can be achieved without increasing the precision of the core of the core or the accuracy required to improve the positioning accuracy of the label. In order to achieve the above-mentioned expectation, it is sufficient to use the analog core 30 indicated by the figures 13(A) and (B). Further, although the cross-sectional view of Fig. 13(A) shows a label, the vent hole is not shown. The region R1 in which the label 1 is wound in the core 30' of this type forms a recess which is depressed toward the center portion Co side of the core-like core 30 than the other region (the region where the label is not wound) R2. That is, as long as the region where the label L is wound is depressed, the label can be wound in the recess. From another point of view, it is formed by the formation region R1 to form a positioning portion for label winding. With this configuration, when the label -31 - 200934637 is adsorbed on the core-like core by suction, the label enters the recessed portion, thereby positioning the label-like core.
