1320769 九、發明說明： 【發明所屬之技術領域】 技術領域 本發明係與一種用於改良在濾紙長度上之密封性質之 5 控制的裝置有關。 特別是與在用於製造過濾包之機器中所進行的方法有關， 該過濾包含有一種用於容納例如茶、浸劑和類似物之產品 為。 【先前技術】 10 登明昔景 在此種機器中，該過濾包的開放端係必須被密封的 (在該產品被填滿至該袋内之後）：該密封作用可以藉由任 何一些已知的方法來達成，舉例來說，其可藉著利用一釘 書針或是將該過濾包與標籤連接之絲線（其係藉著將該絲 15線本身之長度或以其他條絲線來繫結），或是藉著將濾紙 之網狀物的該重疊部分密封而達成。 在密封的情況下，該作業可以藉由具有加熱裝置之傳 密封方式來進行，或者在最新—代的解決方法中，其係 藉由將使用#設置成與該產品接觸的音極之超音波裝置來 20密封。 在實務中，音極係為該轉換元件，其係將能量供應轉 換為被施加於該欲被密封的產品上之振動。 舉例來說，利用此種解決方式之機器係被揭示於本發 申叫人所申凊之專利申請案⑽乃8中。 5 1320769 在該解決方式中，該用於製造用來容納浸劑產品之過 濾包的裝置，係具有一被一第一驅動軸所驅動之旋轉式輸 送輪鼓’以將濾紙的網狀物沿著一路徑來進料，在該路徑 上設置有：一用於將該濾紙網狀物進料之工作站；一用於 5將連續的標籤進料之工作站；一用於進料繫繩的工作站， 该繫繩係將過濾包分別連接至該標籤；一用於依據預定的 模式來設置該繫繩之工作站；與數個面對該進料路徑並被 設計以將該繫繩與該等標籤連結至該濾紙網狀物之密封 器。該等係為音極（sonotr〇(je)之密封器，會在一密封位置 10與等待位置之間進行一預定動作，此一動作係經過一與 所有密封器共同連接之傳動元件，而藉著一第二凸輪傳動 轴來導入該等所有密封器之同時地與同步地的動作該第 二凸輪傳動軸係連接至驅動該輸送輪鼓之第一轴所連接之 同一動力來源。 15 換句話說，該音極係被設置在一相對該底部之較佳位 置上，而濾紙網狀物係在其上移動，此一較佳位置係依據 该濾紙本身的固有性質，而依據其被進料的速度以及欲被 密封的組成物（濾紙、繫繩與標籤）一個疊著一個的厚度 而定。 申"s人已經發現在音極的發射表面與產品支樓表面之 間的相對位置會對良好的密封性質產生一基本的變化。 在實務中’密封性質的一致性也係直接地與音極以及 產品支撐表面之間的接觸力（除了接觸時間和音極作用頻 率之外）成比例，這意味著所施加的壓力應儘可能保持恆 6 丄320769 疋。這一點總是不易達成的，因為該等欲被密封的組成物 (如上所述）在厚度上並不總是完全地相同，而其等之總厚 度會在相當廣泛的範圍中變化；結果，所施加至該等移動 至密封區域（在音極下方）之產品的壓力，會容易在不同 5的產品之間改變，因而導致不一致的密封性質。 本發明因此具有克服上述缺點的目的，其係藉由一會使得 該密封器音極在將被密封的產品上施加一實質上一致的接 觸力，該力的施加係與該產品出現於該密封區域同步。 【發明内容】 10 發明內玄· 依據本發明，本發明之目的可以藉由一用於密封用在 容納浸劑的產品之過濾包的裝置所達成，其至少包含：— 密封音極元件，其係被設置以使其面對一第一路徑，該平 面網狀物係、被沿著該路徑進料，以依據預定的排列模式而 15將该繫繩與標籤彼此密封並密封至該滤紙的平面網狀物·’ 驅動構件’其係用於對該密封音極元件導入一朝向與遠離 一雄封位置之特定動作；該驅動構件依序包含由密封音極 元件所啟動以在該密封音極元件上作用，並且被設計來對 該在封音極兀件本身施加—預定力量之第一構件、用於應 對《亥第構件的作用（也就是，用來減少其之強度）之第二 構件’以及用於在將該渡包組成物通過該密封音極元件下 方的預定步驟時，使該第二構件無法作用之第三控制構 件’以得到一預定的密封接觸。 •1^11要說明 7 本發明與上述目的有關之技術特點，係被明確地描述 在下面的申請專利範圍中，而其之優點可依據參照該等隨 附的圖式之詳細描述而可瞭解，該等例示說明一較佳具體 例之圖式，僅是藉由舉例的方式而不是要限制本發明概念 5 的範圍，且其中： 第1圖係為-用來製造用於浸劑產品之過渡包的裝置 P刀側視圖，4裝置具有依據本發明之密封裝置，以利 用薄膜來包裝產品群組。 第2和3圖係分別為第i圖之裝置的H部分的細節 10之侧視圖和前視圖，其之一些零件係以剖面顯示以增進理 解。 【實施方式】 主發明較_隹具體例之詳細描诂 參照该等隨附的圖式，特別是在第i圖中，依據本發 15明的裝置係被用來密封用在容納浸劑產品之過濾包。 藉著例不說明的方式，每個過濾包是利用濾紙（在第 1圖中以虛線顯示）的平面網狀物i所製成，且其係被附 加一標籤和一將標籤連接至該過濾包本身的繫繩。 該係以元件符號2來代表的裝置之整體，可以形成一 20用於製造整個過濾包並將其等以產品填充之更複雜的機 器。因為這種類型的機器係被詳細地描述於例如與本案相 同的申請人所提出申請之專利申請案B02002A000798的 習知技藝中，其係廣為人知而將不在此贅述。 該裝置2實質上包含有： 8 1320769 --密封音極元件，其係被設置以使其面對一第一路 徑P，該平面網狀物1係被沿著該路徑進料（參照第i 圖中之《 P)’以依據預定的排列模式而將該繫繩ia 與標籤lb彼此密封，並密封至該遽紙的平面網狀物1; 5 -驅動構件4,其彳㈣於㈣㈣音極元件導入一朝 向與遠離一密封位置之特定動作。 如同樣例示說明在第2和3圖中的，該驅動構件4 包含有： -第一構件5，其係被密封音極元件3所啟動設計來 10對該密封音極元件3本身施加一預定力量F(如在第丨圖 中之對應的箭號所示）； .第二構件6，其係用於對應該第一構件5的作用， 也就是’用來減少其之強度； -第二控制構件7，其係用於在將該濾包組成物通過 15該密封音極元件3下方之預定步驟時，使該第二構件6 無法作用，以允許一預定的密封接觸。 更明確地說，在一較佳具體例中，該用於驅動該密封 a極元件3的驅動構件4，可以包含一由凸輪構件9所 驅動的四點連桿組8 (其係被部份地例示說明在第1圖 20 中），其係被設計成會沿著一個別的第二封閉路徑〇而移 動该密封音極元件3的工作端，該封閉路徑包含有_ 该第一路徑P 一致的密封部分s以及一延伸在第—路禋 P之外的返回部分R。 9 1320769 在這個特定的情況中，該第一和第二構件…將 會形成該四點連桿組8的―部份。 更詳，..田地檢視（再次參照第2和3圖），該第一構件 可以由被置在相點連桿组8的該等臂之一上 的螺旋彈簧5m之彈性構件所組成。 該第二構件6可以由—氣虹6c所組成（舉例來說’ 早啟動式），其會將該四點連桿組8的該臂8a之一端形 成該密封音極①件3而在另—端形成凸輪構件9。 ίο 15 20 該氣缸6會容納該螺旋彈簧5m，其係以—種使得在 該密封音極元# 3沿著其之路徑十的前述部分而移動 時’會與該螺旋彈簧作用的方式來界定該第—構件卜 前述的第三控制構件7可以包含—用於將一加壓流 體（例如空氣）加入或排出該氣紅6c之單元^，藉由此 種方式而依據該密封音極元件3所沿著移動的第二路徑 〇之該部分，來改變力量F施加至密封音極元件3的強 度。 換句話說，該空氣係在該密封音極元件3沿著該密 封部分S移動時由氣缸6c排出（因而其只會施加有該 具有微幅過度運轉之彈簧5m的負載 )而該氣虹6c 係在該靜止的該路徑之返回部份R時被以空氣填充 可破了解的是’本發明可以-些方式來修改與調整而不 會因此背離本發明概念的範圍。此外，本發明的所有細節 都可以技術上等效的元件來替換。 【圖式簡單說明】 10 1320769 第1圖係為一用來製造用於浸劑產品之過濾包的裝置 之部分侧視圖，該裝置具有依據本發明之密封裝置，以利 用薄膜來包裝產品群組。 第2和3圖係分別為第1圖之裝置的Η部分的細節 5 之側視圖和前視圖，其之一些零件係以剖面顯示以增進理 解。 【主要元件符號說明】 1 濾紙平面網狀物 7 第三控制構件 la 繫繩 7a 〇〇 早兀 lb 標籤 8 四點連桿組 2 裝置 8a 臂 3 密封音極元件 9 Λ輪構件 4 驅動構件 0 第二封閉路徑 5 第一構件 F 力量 5m 螺旋彈簧 P 第一路徑 6 第二構件 R 返回部分 6c 氣缸 S 密封部分 11
