Description

【0001】
【発明の属する技術分野】
本発明は、特に粉粒体からなる被包装物の供給充填を良好に行うことのできる粉粒体の供給装置に関するものである。
【0002】
【従来の技術】
この種の粉粒体の供給装置としては、ホッパー部材の下側に設けられた粉粒体の供給部と連接して粉粒体を受け入れる粉粒体受入口と粉粒体を送り出す搬出口とを備えた粉粒体移送筒状部材が設けられ、この粉粒体移送筒状部材の内側に粉粒体を水平方向に搬送するスクリュー搬送羽根が設けられたスクリューコンベア部材が配設され、このスクリューコンベア部材に連結され、前記スクリュー搬送羽根を回転駆動することによって前記粉粒体が水平方向に移送されて粉粒体搬出口から粉粒体が供給されるように構成されたものが知られている(たとえば、特許文献1などを参照。)。
【0003】
【特許文献1】
特開平9−253476号公報
【0004】
また粉粒体の性質として粒径の大小や粉体の形状あるいは嵩密度の違いや湿気の度合いなどの諸条件によって粉粒体の流動性などの要素が変化するために、一般的に粉粒体の供給装置では、ホッパー部材の内部では粉粒体を送り出す側の付近においては、スクリューコンベア部材側に向けて粉粒体を集めながら送り出すために窄まった形状(上方が開放状態に壁面が傾斜した形状)となっており、また粉粒体の性質として粒径の大小や粉体の形状あるいは嵩密度の違いや湿気の度合いなどの諸条件によって粉粒体の流動性などの要素が変化するため、粉粒体がホッパーの下端側に設けられた粉粒体受入口の内壁面に付着してしまうことがあり、粉粒体がホッパー部材の内壁面の間に架け渡されて橋状となる架橋現象(ブリッジ現象)が発生してしまうとスクリューコンベア部材に設けられたスクリュー搬送羽根が回転作動しても粉粒体が供給されなくなってしまう。
【0005】
このため前述した特許文献1においては、ホッパー部材の内部側にスクリュー搬送羽根と接触して振動が生じる振動板および振動伝達板を設け、スクリュー搬送羽根の回転に伴う振動板振動により振動伝達板も同時に揺れが生じ、これによりホッパー部材の内部の粉粒体に振動を与えることとなり、ホッパー部材の内部に形成された粉粒体によるブリッジが崩壊される。このため粉粒体はホッパー部材の下部側に円滑に送り込むことができ、スクリュー搬送羽根によって粉粒体を移送することができるように構成している。
【0006】
【発明が解決しようとする課題】
しかしながら、前述した特許文献1にあっては、ホッパー部材の内部側に支持軸、振動板および振動伝達板などの構成要素を収納する必要があり、またその組み付けなど煩わしいものであるとともに、構造的に複雑化してしまうという問題もある。
【0007】
そこで本発明は、従来の問題点に注目し、粉粒体を受け入れる粉粒体受入口の内壁面に粉粒体が付着することを抑制し、安定的に粉粒体を送り出すことのできる粉粒体の供給装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
この請求項1による発明では、粉粒体を貯留するホッパー部材と、このホッパー部材の下端側に連接され前記粉粒体を受け入れる粉粒体受入口と粉粒体を送り出す粉粒体搬出口とを備えた粉粒体移送筒状部材と、この粉粒体移送筒状部材の内側に配設され、粉粒体を水平方向に搬送するスクリュー搬送羽根を設けたスクリューコンベア部材と、このスクリューコンベア部材に連結され、前記スクリュー搬送羽根を回転駆動することによって前記粉粒体を水平方向に移送するための駆動手段と、からなる粉粒体の供給装置において、前記スクリュー搬送羽根の回転方向と対峙する前記粉粒体受入口の壁部を垂直あるいはスクリュー搬送羽根の回転方向と反対側に鋭角に設置してなることを特徴とする粉粒体の供給装置である。
【0009】
また請求項1において、請求項2では、前記スクリュー搬送羽根の回転駆動による粉粒体の移送方向と対峙する前記粉粒体受入口の壁部をほぼ垂直あるいは粉粒体の移送方向と反対側に鋭角に設置してなることを特徴とする粉粒体の供給装置である。
【0010】
また請求項1または請求項2において、請求項3では、前記粉粒体の性質に合わせて前記壁部の取り付け角度を任意に変更可能に設定してなることを特徴とする粉粒体の供給装置である。
【0011】
また請求項1から請求項3のいずれか1項に記載において、請求項4では、前記粉粒体受入口に外部側から振動発生装置によって衝撃を与えてなることを特徴とする粉粒体の供給装置である。
【0012】
また請求項1から請求項4のいずれか1項に記載において、請求項5では、前記粉粒体搬出口には、粉粒体の加圧によって開閉可能に設けられた開閉弁部材を配設してなることを特徴とする粉粒体の供給装置である。
【0013】
また請求項1から請求項5のいずれか1項に記載において、請求項6では、前記駆動手段の回転数あるいは回転速度などを設定することによって粉粒体の供給充填量を制御する制御手段を設けてなることを特徴とする粉粒体の供給装置である。
【0014】
【発明の実施の形態】
本発明の請求項1では、粉粒体を貯留するホッパー部材と、このホッパー部材の下端側に連接され前記粉粒体を受け入れる粉粒体受入口と粉粒体を送り出す粉粒体搬出口とを備えた粉粒体移送筒状部材と、この粉粒体移送筒状部材の内側に配設され、粉粒体を水平方向に搬送するスクリュー搬送羽根を設けたスクリューコンベア部材と、このスクリューコンベア部材に連結され、前記スクリュー搬送羽根を回転駆動することによって前記粉粒体を水平方向に移送するための駆動手段と、からなる粉粒体の供給装置において、前記スクリュー搬送羽根の回転方向と対峙する前記粉粒体受入口の壁部を垂直あるいはスクリュー搬送羽根の回転方向と反対側に鋭角に設置してなることを特徴とする粉粒体の供給装置であるため、スクリュー搬送羽根の回転駆動に伴い、粉粒体が搬送羽根の動きに連れてスクリュー搬送羽根の回転方向と対峙する粉粒体受入口の壁部へと送り込まれながら螺旋状のスクリュー搬送羽根の向きに沿って粉粒体移送筒状部材の内部にて粉粒体が水平方向に移送される。この際、スクリュー搬送羽根の回転方向と対峙する粉粒体受入口の壁部を垂直あるいはスクリュー搬送羽根の回転方向と反対側に鋭角に設置しているため、粉粒体が粉粒体受入口の壁部の内壁面に付着しようとしても壁面が垂直あるいは若干オーバーハングしているため多少は付着はするものの堆積することができずスクリュー搬送羽根によって粉粒体が押されながら一方向に供給案内され、粉粒体移送筒状部材に設けられた粉粒体搬出口を介して粉粒体移送筒状部材の搬出側から充填部へと粉粒体が供給される。この場合、請求項2の構成のように、スクリュー搬送羽根の回転駆動による粉粒体の移送方向と対峙する粉粒体受入口の壁部をほぼ垂直あるいは粉粒体の移送方向と反対側に鋭角に設置してなることにより、同様に壁部に堆積することを未然に予防することができる。
【0015】
また請求項3では、請求項1または請求項2において、前記粉粒体の性質に合わせて前記壁部の取り付け角度を任意に変更可能に設定してなることにより、取り扱う粉粒体の性質、たとえば粉粒体の粒径や粘性や付着性の高い粉粒体あるいは流動性の良い粉粒体などの諸条件に合わせて粉粒体受入口の取り付け角度を設定することにより、粉粒体の付着を抑制しつつ良好に粉粒体を送り出すことが可能となる。
【0016】
また請求項4では、請求項1から請求項3のいずれか1項において、前記粉粒体受入口に外部側から振動発生装置によって衝撃を与えてなることにより、粉粒体受入口の内面部分に付着する粉粒体を、振動発生装置による衝撃によって事前に落下させることができ、粉粒体受入口の壁部の設置条件と相まって壁部への粉粒体の付着、架橋などの現象をさらに抑制することができる。
【0017】
また請求項5では、請求項1から請求項4のいずれか1項において、前記粉粒体搬出口には、粉粒体の加圧によって開閉可能に設けられた開閉弁部材を配設してなることにより、スクリューコンベア部材の回転動作によって送り出される際に生じる粉粒体の加圧あるいは粉粒体の重さによる加圧によって安定した状態にて開閉作動することができるものであり、安定した粉粒体の充填作動を行うことができる。
【0018】
また請求項6では、請求項1から請求項5のいずれか1項に記載において、前記駆動手段の回転数あるいは回転速度などを設定することによって粉粒体の供給充填量を制御する制御手段を設けてなることにより、粉粒体の供給量を簡単に変更することができるという効果がある。この際、粉粒体の粉体、粒体などの粒の大きさ粉粒体の湿り気の度合いなどの諸条件に合わせてスクリーンコンベア部材に設けたスクリュー搬送羽根の回転速度や回転時間などを任意に設定することにより良好に供給することができるという効果がある。
【0019】
【実施例】
以下、本発明の実施例を添付図面を基づいて説明する。本発明に係る粉粒体の供給装置の構造を充填包装装置に適用した例を基にしてその概略構成とその動作について、第1実施例として図1から図4を参照にして述べる。
【0020】
同図において、充填包装装置の全体概要の構成として、包装フィルムFを巻回したフィルム原反1が充填包装装置の機台の側方に設けられた保持枠2に装着されて支持されており、前記フィルム原反1から引き出し案内された包装フィルムFは、フィルム供給案内機構3を介して所定のテンションが付与されて一旦上方へと引き出し案内され、充填包装装置の上部側に設けられたフィルム製袋折返し機構4により包装フィルムFの長手方向に沿って二つ折りに折り返して下方へ引き出し案内するように構成されている。
【0021】
この実施例では、この下方へ引き出し搬送される二つ折りフィルムFは、縦シール機構5へと案内される。縦シール機構5は、たとえばサーボモータからなる駆動手段によって回転可能に設けられ、対向する一対の縦シールロール5Aの外周に沿って2列にそれぞれ設けられた縦シール部材5Bによって、二つ折りに折り返され包装フィルムFが縦方向に各々折返し縁部と折返し端部同志(左右両縁部)との2箇所をそれぞれヒートシールすることによって縦シールFH箇所が包装フィルムFの両側端に形成され、次いで前記縦シール機構5の下方に配設された横シール機構6によってヒートシールされて横シールFS箇所が形成される。
【0022】
この場合、横シール機構6は、たとえばサーボモータからなる駆動手段によって回転可能に設けられ、対向する一対の横シールロール6Aの外周の幅方向に沿ってそれぞれ設けられた横シール部材6Bによって、横方向に所定間隔を置いてヒートシールされて横シールFS箇所が形成され、この横シールFS箇所により包装袋Pとなる有底筒状の底部が形成され、これにより有底筒状に形成された包装フィルムF内に後述する被包装物充填機構7によって粉粒体である被包装物Wが充填され、続いて包装フィルムFを送り出した後に前記横シール機構6の横シールロール6Aに設けられた横シール部材6Bにより包装フィルムFの袋口部となる箇所を横ヒートシールし、この横ヒートシールによる横シールFSによって内容物Wが封止され、次々と連続した状態で四方シールされた包装袋Pが下方へ連続搬送されるように構成されている。
【0023】
また、前記横シール機構6の下方には、上下に連続した状態の包装袋Pの横シールFS箇所のほぼ中央部を切り離して搬出することのできるカッタ刃を備えた切断機構8が配設されている。
【0024】
ところで、この第1実施例における粉粒体の供給装置として、フィルムFを二つ折りに折り返すためのフィルム製袋折返し機構4の下流側に、被包装物(粉粒体)Wを供給するための供給装置である被包装物充填機構7が設けられている。この被包装物充填機構7には、粉粒体からなる被包装物Wを貯留する逆円錐形のホッパー部材11が設けられるとともに、このホッパー部材11の側方には粉粒体である被包装物Wを投入可能な投入口12が設けられるとともに、ホッパー部材11の下端側には被包装物Wを送り込む筒状の供給用開口部13が設けられている。この筒状の供給用開口部13と同軸上にスクリューフィーダ14が設けられ、このスクリューフィーダ14の軸14Aにはホッパー部材11の内壁に付着する粉粒体Wを掻き落とすスクレーパ15が前記軸14Aと同軸上にして回転可能にホッパー部材11の内壁に沿って設けられている。
【0025】
なお、前記スクリューフィーダ14と前記スクレーパ15とは軸14A側と連結された駆動用モータ16を介して回転可能に設けられるとともに、スクリューフィーダ14の回転方向とスクレーパ15の回転方向とは互いに逆回転で回転駆動するように設定されており、粉粒体Wの送りを安定にし、粉粒体Wの攪拌を助長することをねらいとしている。
【0026】
またホッパー部材11の下端側に設けられた供給用開口部13の下方側には、その供給用開口部13側と連接されて搬送用トラフ17が所定の角度に傾斜して配置され、その搬送用トラフ17と接して配設されたバイブレータ17Aの作動によって搬送用トラフ17上に搬送されてきた粉粒体Wを送り出すことができるように構成している。
【0027】
また搬送用トラフ17の搬出端側には、その搬送用トラフ17側と連接されて粉粒体受入口である受入部18が備え付けられた粉粒体移送筒状部材19を横向きに配置している。
【0028】
またホッパー部材11の供給用開口部13から送り出された粉粒体Wは、搬送用トラフ17を経て粉粒体W(被包装物W)が粉粒体受入口である受入部18を介して粉粒体移送筒状部材19へと送り込まれる。粉粒体移送筒状部材19の筒状内部側には、スクリューコンベア部材20が配設されており、このスクリューコンベア部材20には螺旋状のスクリュー搬送羽根20Aが設けられるとともに、被包装部Wである粉粒体Wの粉体,粒体などの粒の大きさなどの条件に合わせてその螺旋状のスクリュー搬送羽根20Aのピッチや外形寸法などを設定することにより、良好に粉粒体Wである被包装物Wを送り出すことが可能となるように構成されている。
【0029】
また螺旋状のスクリュー搬送羽根20Aからなるスクリューコンベア部材20の端部側と連結され、そのスクリューコンベア部材20を回転駆動することによって前記被包装物(粉粒体)Wを包装袋P内の充填部へと移送するための駆動手段21であるサーボモータが備えられ、その駆動手段21の回転数あるいは回転速度などを設定することによって粉粒体Wの供給充填量を制御する制御手段22が設けられている。
【0030】
また粉粒体Wを送り出す粉粒体移送筒状部材19の筒状端部側には、その下側に粉粒体搬出口23が設けられるとともに、この粉粒体搬出口23に金属製材料からなる平板状の弾性を有する開閉弁部材24が閉じ塞ぐように設けられている。この場合、第1実施例にあっては、開閉弁部材24は粉粒体Wの加圧によって一方側を支点として開閉可能に設けられている。
【0031】
また粉粒体Wの性質に合わせて粉粒体Wの供給状態を任意に設定可能とする調整機構25が設けられている。この調整機構25としては、粉粒体移送筒状部材19の軸線方向に沿って移動可能に調整駒部材26が取り付けられるとともに、この調整駒部材26に前記開閉弁部材24がプレート状の調整支持部材27を介してビスなどの固定部材28にて固定支持されている。
【0032】
また粉粒体Wを送り出す粉粒体移送筒状部材19の筒状端部側に位置した粉粒体搬出口23を閉塞している開閉弁部材24の周囲を取り巻いて、その筒状端部の下側に位置した粉粒体搬出口23から送り出される粉粒体Wを、包装フィルムFが折り返されて製袋されながら縦シールされた包装袋Pの充填部箇所に供給するための投入シュート29が設置されている。
【0033】
この第1実施例では、ホッパー部材11の供給用開口部13から送り出された粉粒体Wは、搬送用トラフ17を経て粉粒体W(被包装物W)が粉粒体受入口である受入部18を介して粉粒体移送筒状部材19へと送り込まれるように構成されている。この際、粉粒体受入口である受入部18は四方が周壁30にて囲まれて外部へと粉粒体Wがこぼれ落ちないように形成されている。
【0034】
受入部18を構成する四方が囲まれて形成された粉粒体受入口となる周壁30は、図4に示されているように粉粒体移送筒状部材19の筒状内部側に配置されているスクリュー搬送羽根20Aの回転方向と対峙している壁部30Aがスクリュー搬送羽根20Aの回転方向と反対側にオーバーハングした状態に鋭角に設置されている。
【0035】
またスクリュー搬送羽根20Aの回転駆動による粉粒体Wの移送方向と対峙する粉粒体受入口となる周壁30の一部を構成する壁部30Bはほぼ垂直に設置されている。また搬送用トラフ17の搬出端側に位置した粉粒体受入口となる周壁30の一部を構成する壁部30Cは、搬送用トラフ17の傾斜にほぼ倣って鈍角に傾斜状態にして設置されている。
【0036】
また粉粒体受入口となる周壁30の外部側には、バイブレータなどからなる振動発生装置31が配設されている。
【0037】
従って、上記構成からなる本発明の充填包装機においては、フィルム巻反1から引き出された包装フィルムFは、フィルム案内機構3を介して引き出し案内され、次いで充填包装機の上部側に設けられたフィルム製袋折返し機構4によって包装フィルムFが二つ折りに折り返されて下方へと引き出し案内され、縦シール機構5によって筒状にヒートシールされた後、横シール機構6によって包装袋Pの底部となる箇所がヒートシールされる。
【0038】
このように横シールFS箇所によって包装袋Pの底部が形成されて充填可能となったところへ、被包装物充填機構7に設けられたホッパー部材11の内部側に配置されたスクリューフィーダ14とスクレーパ15とを回転駆動する駆動用モータ16の作動によって、ホッパー部材11の内部に貯留されている粉粒体Wがスクリューフィーダ14とスクレーパ13とにより攪拌されながら供給用開口部13から送り出される。
【0039】
この送り出された粉粒体Wは、搬送用トラフ17上に載せられ、バイブレータ17Aの作動によって搬送用トラフ17の傾斜に沿って搬送され、搬送用トラフ17の搬出側に配設された受入部18を備えた粉粒体移送筒状部材19内へと供給される。
【0040】
そして、粉粒体移送筒状部材19の内部へと供給された粉粒体Wは、粉粒体移送筒状部材19の内部に配設されているスクリューコンベア部材20が駆動手段21であるサーボモータの作動によって回転動作し、螺旋状のスクリュー搬送羽根20Aにより送り出されて一方向に供給案内される。
【0041】
すなわち、スクリューコンベア部材20に設けられた螺旋状のスクリュー搬送羽根20Aの回転作動によって送られながら粉粒体Wが粉粒体移送筒状部材20の一方側に向けて圧送され、この圧送により粉粒体移送筒状部材20の下側に設けられた粉粒体搬出口23から粉粒体Wが下側に向けて押し出される。
【0042】
この時、粉粒体Wの押し圧によって粉粒体搬出口23を閉じ塞いでいた開閉弁部材24が撓んで粉粒体搬出口23が開放され、この開放作動によって粉粒体移送筒状部材19の搬出側(粉粒体搬出口23)から投入シュート29を介して包装袋Pの充填部へと粉粒体Wが移送供給される。
【0043】
ところで、ホッパー部材11の内部に貯留されている粉粒体Wがスクリューフィーダ14とスクレーパ13とにより攪拌されながら供給用開口部13から送り出され、この送り出された粉粒体Wは、搬送用トラフ17を介して受入部18を構成する四方が囲まれて形成された粉粒体受入口となる周壁30へと送り込まれる。
【0044】
送り込まれた粉粒体Wは、スクリューコンベア部材20の回転動作によって螺旋状のスクリュー搬送羽根20Aの回転に連れて粉粒体Wが粉粒体受入口となる受入部18を介して粉粒体移送筒状部材19の内部側へと送り込まれるように作用する。すなわち、スクリュー搬送羽根20Aの回転駆動に伴い、粉粒体Wが搬送羽根20Aの動きに連れてスクリュー搬送羽根20Aの回転方向と対峙する粉粒体受入口となる受入部18の壁部30A側へと送り込まれながら螺旋状のスクリュー搬送羽根20Aの向きに沿って粉粒体移送筒状部材19の内部にて粉粒体Wが水平方向に移送される。
【0045】
この際、スクリュー搬送羽根20Aの回転方向と対峙する粉粒体受入口である受入部18の壁部30Aが搬送羽根20Aの回転方向と反対側にオーバーハングした状態に鋭角に設置されているため、粉粒体Wが粉粒体受入口となる受入部18(粉粒体受入口となる周壁30)の内壁面に付着しようとしても壁面が若干オーバーハングしているため多少は付着はするものの堆積することもなくスクリュー搬送羽根20Aによって粉粒体Wが押されながら一方向に供給案内され、粉粒体移送筒状部材19に設けられた粉粒体搬出口23を介して粉粒体移送筒状部材19の搬出側から投入シュート29を介して包装袋Pの充填部へと粉粒体Wが送り出されて供給される。
【0046】
またスクリュー搬送羽根20Aの回転駆動による粉粒体Wの移送方向と対峙する粉粒体受入口の壁部30Bをほぼ垂直に設置してなることにより、螺旋状のスクリュー搬送羽根20Aによってその回転駆動に伴い、粉粒体Wが粉粒体受入口である受入部18を介して粉粒体移送筒状部材19へと送り込まれる際に、粉粒体Wの移送方向と対峙する粉粒体受入口の壁部30Bをほぼ垂直に設置することによって送り出された粉粒体Wがその壁部30Bに向かって押された際に粉粒体Wの自重などにより堆積することなく落下して粉粒体移送筒状部材19の内部側へと供給され、これにより従来の問題点であった粉粒体受入口の壁部への粉粒体付着によるブリッジ現象の発生を未然に予防することができる。
【0047】
また粉粒体受入口となる周壁30の外部側からバイブレータなどからなる振動発生装置31によって連続的な振動による衝撃を与えてなることにより、粉粒体受入口となる周壁30、特に螺旋状のスクリュー搬送羽根20Aの回転作動によって付着しやすくなる壁部30A,30Bの内面部分に付着する粉粒体Wを、振動発生装置31による衝撃によって事前に落下させることができ、粉粒体受入口の壁部30A,30Bの取り付け角度による設置条件と相まって壁部30A,30Bへの粉粒体Wの付着、架橋などの現象をさらに抑制することができる。
【0048】
なお、図示はしないが、取り扱う粉粒体Wの性質、たとえば粉粒体Wの粒径や粘性や付着性の高い粉粒体Wあるいは流動性の良い粉粒体Wなどの諸条件に合わせて粉粒体受入口となる周壁30(壁部30A,30B)の取り付け角度を任意に変更可能に設定することにより、粉粒体Wの付着を抑制しつつ良好に粉粒体Wを送り出すことが可能となる。
【0049】
このようにして粉粒体移送筒状部材19の筒状内部側に螺旋状のスクリュー搬送羽根20Aの回転作動によって送り込まれた粉粒体W(被包装物W)は、粉粒体移送筒状部材19に設けられた粉粒体搬出口23の位置へと送られてくると、スクリューコンベア部材20の回転動作によって送り出される際に生じる粉粒体Wの加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23を閉じ塞いでいた開閉弁部材24に加わることによって開閉弁部材24が撓んで粉粒体搬出口23が開放され、この開放によって粉粒体Wがその隙間から流れ落ちることにより、開閉弁部材24に加わる粉粒体Wの加圧力がなくなることによって開閉弁部材24が元の状態に復帰しようとして作用し、続いてスクリューコンベア部材20の回転動作が継続している間は、粉粒体Wの加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23を閉じ塞いでいた開閉弁部材24に加わったりあるいは軽減したりする状態の繰り返しにより、開閉弁部材24が細かく開閉作動することによって粉粒体Wが順次供給される。
【0050】
次いで、駆動手段21であるサーボモータの作動が停止することにより、スクリュー搬送羽根20Aの回転作動も停止することとなり、これにより粉粒体Wの圧送による加圧力がなくなるため、開閉弁部材24が最初の状態へと復帰して粉粒体搬出口23が閉じられ、粉粒体Wの供給が停止する。
【0051】
従って、開閉弁部材24の開閉作動によって所定量の粉粒体Wが包装袋P内へと供給されるとともに、スクリュー搬送羽根20Aの回転作動による加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23に作用しなくなると開閉弁部材24が粉粒体搬出口23を閉じ塞ぐ状態(遮断状態)となるため、粉粒体Wが粉粒体搬出口23からこぼれ落ちることがなくなり、この結果、横シール機構6によって包装袋Pの底部となる箇所がヒートシールする際に包装袋P内に粉粒体Wを噛み込むことを抑制することができ、包装袋Pの横シールFSの状態を良好に保ちながらヒートシールを行うことができる。
【0052】
また粉粒体Wの性質に合わせて、たとえば流動性がよくフラッシングを起こしやすい性質を持つ粉粒体Wにあっては、調整機構25の一部を構成する調整駒部材26を粉粒体移送筒状部材19の軸線方向に沿って移動調整して粉粒体搬出口23を開閉弁部材24によって閉じ塞ぐように配置することにより、粉粒体Wのフラッシング現象によって粉粒体Wが粉粒体搬出口23からこぼれ落ちることを未然に防ぐことができるものであり、また粉粒体Wの粒径や形状によっては粉粒体W同士が付着し易くなってブリッジング現象が生じやすい場合にあっては、粉粒体搬出口23を開口するように設定することで粉粒体Wの詰まりなどを防ぎつつ送り出すことも可能であり、また粉粒体Wの形状や粒径、湿り気などの諸条件による性質の違いによって、粉粒体搬出口23の開口度合いや開閉弁部材24の弾性度合いを任意に設定することにより、安定した状態にて粉粒体Wを送り出すことが可能となる。
【0053】
また、製袋された包装袋Pの包装仕様に合わせて粉粒体Wの供給充填量を制御手段22によって設定することで、所定の充填量を簡単に変更することができるものであり、その設定条件として、たとえば駆動手段21であるサーボモータの回転数や回転速度あるいは回転時間の設定などによって粉粒体Wの供給量の調整、設定が可能となるものである。
【0054】
また図5から図7は本発明の第2実施例を示すものであり、この第2実施例では、一枚の包装フィルムFを半折り状態に折り返しながら引き出し案内し、この半折りに折り返された折返し端部と折り返されたフィルムFの中央部および折返し端縁(左右両縁部と中間部)とが縦シール機構5の対をなす縦シールロール5Aにそれぞれ設けられた三つの縦シール部材5Bによって縦方向に縦シールFHして二列に筒状に製袋された包装袋Pを成形し、その一方の列に被包装物充填機構7に設けられた粉粒体移送筒状部材19の搬出側に投入シューター29を臨ませて配置して粉粒体Wを充填供給可能とし、他方の列に被包装物充填機構7に設けられた液状供給用の液状充填ノズル32を臨ませて配置して液状の被包装物W1を充填供給するようにしている。(図5参照)
【0055】
また第2実施例では、ホッパー部材11の内部側には、攪拌用のスクレーパ15を配設することなく、送り出しのためのスクリューフィーダー14のみが配設され、それを回転駆動するための駆動用モータ16が設けられている。またホッパー部材11の下端側には、粉粒体Wを送り込む筒状の供給用開口部13が設けられ、この供給用開口部13の下方側には、その供給用開口部13側と連接して粉粒体受入口である受入部18が形成された粉粒体移送筒状部材19が横向きに配置されている。
【0056】
この場合、粉粒体受入口である受入部18は四方が周壁30にて囲まれてホッパー部材11の供給用開口部13から外部へと粉粒体Wがこぼれ落ちないように形成されている。
【0057】
受入部18を構成する四方が囲まれて形成された粉粒体受入口となる周壁30は、図 に示されているように粉粒体移送筒状部材19の筒状内部側に配置されているスクリュー搬送羽根20Aの回転方向と対峙している壁部30Aがスクリュー搬送羽根20Aの回転方向と反対側にオーバーハングした状態に鋭角に設置されている。
【0058】
またスクリュー搬送羽根20Aの回転駆動による粉粒体Wの移送方向と対峙する粉粒体受入口となる周壁30の一部を構成する壁部30Bは、その粉粒体Wの移送方向と反対側に鋭角に設置されている。
【0059】
また粉粒体受入口となる周壁30の外部側には、シリンダによるピストンの往復作動によって粉粒体受入口側に間欠的に衝撃を与える振動発生装置31Aが配設されている。この場合、たとえば粉粒体Wの供給時において所定の間隔にて粉粒体受入口となる周壁30の外部側に衝撃を与えるように構成している。
【0060】
また第2実施例においては、被包装物充填機構7に設けられた粉粒体移送筒状部材19の先端側壁部に粉粒体搬出口23が設けられ、その粉粒体搬出口23に開閉弁部材24が閉じ塞ぐように設けられている。この場合、開閉弁部材24は粉粒体Wの性質、すなわち、粉粒体Wの流動性に合わせて粉粒体搬出口23の開口度合いを調整可能に取り付けたり、粉粒体Wの性質によっては、若干の湿り気がある場合などでは、粉粒体搬出口23にプレート状の開閉弁部材24を取り付けることなく開放状態に設け、スクリュー搬送羽根20Aの送りのみにて粉粒体Wを投入シュート29側へと供給するように配設することもある。
【0061】
従って、上記構成からなる本発明の充填包装機においては、前述した第1実施例と同様にして横シールFS箇所によって包装袋Pの底部が形成されて充填可能となったところへ、被包装物充填機構7の駆動手段21であるサーボモータが作動して、ホッパー部材11の内部に貯留されている粉粒体Wが粉粒体移送筒状部材19の内部に配設されているスクリューコンベア部材20の回転動作によって送り出されて一方向に供給案内される。
【0062】
続いて、粉粒体Wの押し圧によって粉粒体搬出口23を閉じ塞いでいた開閉弁部材24が上方側を支点として下側が横方向に向けて撓んで粉粒体搬出口23が開放され、この開放作動によって粉粒体移送筒状部材19の先端側から投入シュート29を介して包装袋Pの充填部へと粉粒体Wが供給される。
【0063】
ところで、ホッパー部材11の内部に貯留されている粉粒体Wがスクリューフィーダ14により攪拌されながら供給用開口部13から送り出され、この送り出された粉粒体Wは、供給用開口部13と連結された受入部18を構成する四方が囲まれて形成された粉粒体受入口となる周壁30へと送り込まれ、送り込まれた粉粒体Wは、スクリューコンベア部材20の回転動作によって螺旋状のスクリュー搬送羽根20Aの回転に連れて粉粒体Wが粉粒体受入口となる受入部18を介して粉粒体移送筒状部材19の内部側へと送り込まれるように作用する。
【0064】
すなわち、スクリュー搬送羽根20Aの回転駆動に伴い、粉粒体Wが搬送羽根20Aの動きに連れてスクリュー搬送羽根20Aの回転方向と対峙する粉粒体受入口となる受入部18の壁部30A側へと送り込まれながら螺旋状のスクリュー搬送羽根20Aの向き(送り方向)に沿って粉粒体移送筒状部材19の内部にて粉粒体Wが水平方向に移送される。
【0065】
この際、前述した第1実施例と同様にして、スクリュー搬送羽根20Aの回転方向と対峙する粉粒体受入口である受入部18の壁部30Aが搬送羽根20Aの回転方向と反対側にオーバーハングした状態に鋭角に設置されているため、粉粒体Wが粉粒体受入口となる受入部18(粉粒体受入口となる周壁30)の内壁面に付着しようとしても壁面が若干オーバーハングしているため多少は付着はするものの堆積することもなくスクリュー搬送羽根20Aによって粉粒体Wが押されながら一方向に供給案内され、粉粒体移送筒状部材19に設けられた粉粒体搬出口23を介して粉粒体移送筒状部材19の搬出側から投入シュート29を介して包装袋Pの充填部へと粉粒体Wが送り出されて供給される。
【0066】
またスクリュー搬送羽根20Aの回転駆動による粉粒体Wの移送方向と対峙する粉粒体受入口の壁部30Bが粉粒体Wの移送方向と反対側に鋭角に設置されていることにより、螺旋状のスクリュー搬送羽根20Aによってその回転駆動に伴い、粉粒体Wが粉粒体受入口である受入部18を介して粉粒体移送筒状部材19へと送り込まれる際に、粉粒体Wの移送方向と対峙する粉粒体受入口の壁部30Bを粉粒体Wの移送方向と反対側に鋭角に設置することによって送り出された粉粒体Wがその壁部30Bに向かって押された際に壁部30Bの斜面に倣って送り込まれるため、粉粒体Wの自重などにより堆積することなく落下して粉粒体移送筒状部材19の内部側へと安定した状態にて供給されるものであり、これにより従来の問題点であった粉粒体受入口の壁部への粉粒体付着によるブリッジ現象の発生を未然に予防することができる。
【0067】
また粉粒体受入口となる周壁30の外部側からピストンの往復作動による振動発生装置31Aによって間欠的に衝撃を与えることにより、粉粒体受入口である周壁30、特に螺旋状のスクリュー搬送羽根20Aの回転作動によって付着しやすくなる壁部30A,30B箇所の内面部分に付着する粉粒体Wを、振動発生装置31による衝撃によって事前に落下させることができ、粉粒体受入口の壁部30A,30Bの取り付け角度による設置条件と相まって壁部30A,30Bへの粉粒体Wの付着、架橋などの現象をさらに抑制することができる。
【0068】
この際、前述した第1実施例とほぼ同様に、螺旋状のスクリュー搬送羽根20Aの回転作動によって送られてくる粉粒体Wは、粉粒体移送筒状部材19の先端側に設けられた粉粒体搬出口23の位置へと送られてくると、スクリューコンベア部材20の回転動作によって送り出される際に生じる粉粒体Wの加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23を閉じ塞いでいた開閉弁部材24に加わることによって開閉弁部材24が撓んで粉粒体搬出口23が開放され、この開放によって粉粒体Wがその粉粒体搬出口23の隙間から流れ落ちることにより、開閉弁部材24に加わる粉粒体Wの加圧力がなくなることによって開閉弁部材24が元の状態に復帰するように作用し、続いてスクリューコンベア部材20の回転動作が継続している間は、粉粒体Wの加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23を閉じ塞いでいた開閉弁部材24に加わったりあるいは軽減したりする状態の繰り返しにより、開閉弁部材24が細かく開閉作動することによって粉粒体Wが順次供給される。
【0069】
従って、開閉弁部材24の開閉作動によって所定量の粉粒体Wが包装袋P内へと供給されるとともに、スクリュー搬送羽根20Aの回転作動による加圧力あるいは粉粒体W自体の重さによる加圧力が粉粒体搬出口23に作用しなくなると開閉弁部材24が粉粒体搬出口23を閉じ塞ぐ状態(遮断状態)となるため、粉粒体Wが粉粒体搬出口23からこぼれ落ちることがなく、この結果、横シール機構6によって包装袋Pの底部となる箇所がヒートシールする際に包装袋P内に粉粒体Wを噛み込むことを抑制することができ、包装袋Pの横シールFSの状態を良好に保ちながらヒートシールすることができる。
【0070】
なお、本発明は上述した実施例に限定されるものでなく本発明の要旨の範囲において種々の変形実施が可能であり、前述した第1実施例および第2実施例においてはホッパー部材の内部側には、粉粒体Wの送り出しのためのスクリューフィーダー14や攪拌用のスクレーパ15を配設した例を示したが、場合によってはホッパー部材11の内部側に、攪拌用のスクレーパ15や送り出しのためのスクリューフィーダー14を配設することなく、粉粒体Wの自由落下を利用して送り出す構造を採用してもよいものであり、この場合、ホッパー部材11の下端側には粉粒体Wを送り出す筒状の供給用開口部13が設けられ、この供給用開口部13の下方側に連接状態にして粉粒体受入口となる受入部18と粉粒体を送り出す粉粒体搬出口23を備えた粉粒体移送筒状部材19において、少なくともスクリュー搬送羽根20Aの回転方向と対峙する粉粒体受入口の壁部を垂直あるいはスクリュー搬送羽根20Aの回転方向と反対側に鋭角に設置してなる構造を採用することにより、粉粒体受入口の壁部への粉粒体Wの付着現象あるいは粉粒体Wの架橋によるブリッジ現象を防ぐことが可能となるものであり、壁部の長さや形状、あるいは壁部の取り付け角度や向きの設定など適宜変更可能である。また充填包装機として、たとえば縦型の充填包装機においては、セーラー板によって筒状に製袋しつつ粉粒体を供給して充填包装するものや、横型の充填包装機において、それぞれ得られる包装袋の製袋過程において、粉粒体を充填するタイプのものなど適宜実施することも可能である。
【0071】
【発明の効果】
以上詳述したように、本発明による粉粒体の供給装置においては、スクリュー搬送羽根の回転方向と対峙する粉粒体受入口の壁部を垂直あるいはスクリュー搬送羽根の回転方向と反対側に鋭角に設置してなることにより、粉粒体が粉粒体受入口の内壁面に付着しようとしても壁面が垂直あるいは若干オーバーハングしているため多少は付着はするものの堆積することなくスクリュー搬送羽根によって粉粒体が押されながら一方向に供給案内され、粉粒体移送筒状部材に設けられた粉粒体搬出口を介して粉粒体移送筒状部材の搬出側から充填部へと粉粒体を安定した状態にて供給することができる。また、スクリュー搬送羽根の回転駆動による粉粒体の移送方向と対峙する粉粒体受入口の壁部をほぼ垂直あるいは粉粒体の移送方向と反対側に鋭角に設置してなることにより、同様に壁部に堆積することを未然に予防することができるものであり、これにより粉粒体受入口の壁部への粉粒体Wの付着現象あるいは粉粒体Wの架橋によるブリッジ現象を防ぐことが可能となるものであり、初期の目的を達成することができる。

[0033]
In the first embodiment, the granular material W sent out from the supply opening 13 of the hopper member 11 passes through the trough 17 for conveyance, and the granular material W (package W) is the granular material receiving port. It is configured to be fed into the granular material transfer cylindrical member 19 through the receiving portion 18. At this time, the receiving portion 18 that is a powder particle receiving port is surrounded by the peripheral wall 30 so that the powder particles W are not spilled to the outside.
[0034]
The peripheral wall 30 which becomes the granular material receiving port formed by surrounding the four sides constituting the receiving portion 18 is arranged on the cylindrical inner side of the granular material transfer cylindrical member 19 as shown in FIG. The wall portion 30A facing the rotation direction of the screw conveying blade 20A is installed at an acute angle in a state where it is overhanging on the opposite side to the rotation direction of the screw conveying blade 20A.
[0035]

Further, the wall portion 30 </ b> C constituting a part of the peripheral wall 30 serving as the granular material receiving port located on the carry-out end side of the conveying trough 17 is installed in an obtuse angle inclined state substantially following the inclination of the conveying trough 17. ing.
[0036]
Further, a vibration generating device 31 made of a vibrator or the like is disposed on the outer side of the peripheral wall 30 serving as a powder particle receiving port.
[0037]
Therefore, in the filling and packaging machine of the present invention having the above-described configuration, the packaging film F drawn out from the film roll 1 is guided through the film guide mechanism 3 and then provided on the upper side of the filling and packaging machine. After the packaging film F is folded in half by the film bag folding mechanism 4 and drawn and guided downward, it is heat sealed in a cylindrical shape by the vertical sealing mechanism 5 and then becomes the bottom of the packaging bag P by the horizontal sealing mechanism 6. The part is heat sealed.
[0038]
Thus, the screw feeder 14 and the scraper disposed on the inner side of the hopper member 11 provided in the package filling mechanism 7 are formed where the bottom portion of the packaging bag P is formed by the position of the lateral seal FS and can be filled. 15, the powder W stored in the hopper member 11 is sent out from the supply opening 13 while being stirred by the screw feeder 14 and the scraper 13.
[0039]
The delivered granular material W is placed on the transport trough 17, transported along the inclination of the transport trough 17 by the operation of the vibrator 17 </ b> A, and a receiving portion disposed on the transport side of the transport trough 17. 18 is supplied into the granular material transfer cylindrical member 19 having 18.
[0040]
The granular material W supplied to the inside of the granular material transfer cylindrical member 19 is a servo in which the screw conveyor member 20 disposed inside the granular material transfer cylindrical member 19 is the drive means 21. The motor is rotated by the operation of the motor, is fed out by the spiral screw conveying blade 20A, and is supplied and guided in one direction.
[0041]
That is, the granular material W is pumped toward one side of the granular material transporting cylindrical member 20 while being sent by the rotational operation of the helical screw conveying blade 20A provided on the screw conveyor member 20, and the powder is fed by this pressure feeding. The granular material W is extruded toward the lower side from the granular material outlet 23 provided on the lower side of the granular material transfer cylindrical member 20.
[0042]
At this time, the opening / closing valve member 24 that closes and closes the granular material outlet 23 by the pressing force of the granular material W is bent to open the granular material outlet 23, and the granular material transfer cylindrical member is opened by this opening operation. The granular material W is transported and supplied from the unloading side 19 (the granular material outlet 23) to the filling portion of the packaging bag P through the charging chute 29.
[0043]
By the way, the granular material W stored inside the hopper member 11 is fed out from the supply opening 13 while being stirred by the screw feeder 14 and the scraper 13, and the fed granular material W is used as a transportation trough. 17 is sent to a peripheral wall 30 serving as a granular material receiving port formed by surrounding four sides constituting the receiving unit 18 through 17.
[0044]
The granular material W fed in is granular material through the receiving part 18 in which the granular material W becomes a granular material receiving port with the rotation of the spiral screw conveying blade 20A by the rotation operation of the screw conveyor member 20. It acts so as to be fed into the inside of the transfer cylindrical member 19. That is, with the rotational drive of the screw conveying blade 20A, the wall portion 30A side of the receiving portion 18 serving as the granular material receiving port facing the rotational direction of the screw conveying blade 20A as the conveying blade 20A moves. The granular material W is transferred in the horizontal direction inside the granular material transfer cylindrical member 19 along the direction of the spiral screw conveying blade 20A.
[0045]
At this time, the wall portion 30A of the receiving portion 18 which is a granular material receiving port facing the rotation direction of the screw conveying blade 20A is installed at an acute angle in an overhanging state opposite to the rotation direction of the conveying blade 20A. Even if the granular material W tries to adhere to the inner wall surface of the receiving portion 18 (peripheral wall 30 serving as the granular material receiving port) serving as the granular material receiving port, the wall surface is slightly overhanging, but is somewhat adhered. The granular material W is fed and guided in one direction while being pushed by the screw conveying blade 20A without being deposited, and the granular material is transferred through the granular material outlet 23 provided in the granular material transfer cylindrical member 19. From the carrying-out side of the cylindrical member 19, the granular material W is sent and supplied to the filling part of the packaging bag P through the charging chute 29.
[0046]
Further, the wall portion 30B of the granular material receiving port facing the transfer direction of the granular material W by the rotational driving of the screw conveying blade 20A is installed substantially perpendicularly, so that the rotational driving is performed by the helical screw conveying blade 20A. Accordingly, when the granular material W is sent to the granular material transfer cylindrical member 19 through the receiving portion 18 which is the granular material receiving port, the granular material reception which opposes the transfer direction of the granular material W. When the granular material W fed out by installing the wall portion 30B of the entrance almost vertically is pushed toward the wall portion 30B, it falls without being deposited due to its own weight, etc. It is supplied to the inner side of the body transfer cylindrical member 19, thereby preventing the occurrence of a bridging phenomenon due to the adhesion of the granular material to the wall portion of the granular material receiving port, which has been a conventional problem. .
[0047]
Moreover, the peripheral wall 30 used as a granular material entrance, especially helical shape by giving the impact by continuous vibration by the vibration generator 31 which consists of vibrators etc. from the outer side of the peripheral wall 30 used as a granular material entrance. The granular material W adhering to the inner surface portions of the wall portions 30A and 30B that are easily adhered by the rotation operation of the screw conveying blade 20A can be dropped in advance by an impact by the vibration generating device 31, and Coupled with the installation conditions depending on the mounting angles of the wall portions 30A, 30B, it is possible to further suppress phenomena such as adhesion of the granular material W to the wall portions 30A, 30B and crosslinking.
[0048]
In addition, although not shown in figure, according to conditions, such as the particle size W of the granular material W to handle, for example, the granular material W of a granular material W with high viscosity and adhesiveness, or the granular material W with good fluidity. By setting the attachment angle of the peripheral wall 30 (wall portions 30A, 30B) serving as the granular material receiving port to be arbitrarily changeable, the granular material W can be sent out satisfactorily while suppressing the adhesion of the granular material W. It becomes possible.
[0049]
Thus, the granular material W (package W) fed into the cylindrical inner side of the granular material transfer cylindrical member 19 by the rotational operation of the spiral screw conveying blade 20A is the granular material transfer cylindrical shape. When it is sent to the position of the granular material outlet 23 provided in the member 19, the pressure of the granular material W generated when it is sent out by the rotational operation of the screw conveyor member 20 or the weight of the granular material W itself. The pressure applied by the pressure is applied to the opening / closing valve member 24 that has closed and closed the granular material outlet 23, whereby the opening / closing valve member 24 is bent and the granular material outlet 23 is opened. By flowing down from the gap, the pressure of the granular material W applied to the on-off valve member 24 is eliminated, so that the on-off valve member 24 acts to return to the original state, and then the screw conveyor member 20 rotates. During the duration, the pressure applied by the granular material W or the pressure due to the weight of the granular material W itself is applied to or reduced by the on-off valve member 24 closing and closing the granular material outlet 23. By repeating the state, the on-off valve member 24 is finely opened and closed, whereby the granular materials W are sequentially supplied.
[0050]
Next, when the operation of the servo motor which is the driving means 21 is stopped, the rotation operation of the screw conveying blade 20A is also stopped. As a result, the pressurizing force due to the pressure feeding of the granular material W is eliminated. Returning to the initial state, the granular material outlet 23 is closed, and the supply of the granular material W is stopped.
[0051]
Accordingly, a predetermined amount of the granular material W is supplied into the packaging bag P by the opening / closing operation of the on-off valve member 24, and the pressure due to the rotational operation of the screw conveying blade 20A or the weight of the granular material W itself is applied. When the pressure no longer acts on the granular material outlet 23, the on-off valve member 24 closes and closes the granular material outlet 23 (blocking state), so that the granular material W falls down from the granular material outlet 23. As a result, when the part which becomes the bottom part of the packaging bag P is heat-sealed by the horizontal sealing mechanism 6, it is possible to suppress the biting of the granular material W into the packaging bag P. Heat sealing can be performed while keeping the state of the lateral seal FS good.
[0052]
Further, according to the properties of the granular material W, for example, in the case of the granular material W having a good fluidity and a tendency to cause flushing, the adjusting piece member 26 constituting a part of the adjusting mechanism 25 is transferred to the granular material. By moving and adjusting along the axial direction of the cylindrical member 19 and disposing the granular material outlet 23 so as to be closed and closed by the on-off valve member 24, the granular material W becomes granular due to the flushing phenomenon of the granular material W. It is possible to prevent spilling from the body outlet 23, and depending on the particle size and shape of the powder W, the powder W easily adheres and bridging phenomenon is likely to occur. Then, it is possible to send out while preventing the clogging of the granular material W by setting the granular material outlet 23 to open, and the shape, particle size, wetness, etc. of the granular material W are also possible. Due to differences in properties due to various conditions Te, by arbitrarily setting the elastic degree of opening degree and closing valve member 24 of the granular material outlet port 23, it is possible to feed the granular material W at a stable state.
[0053]
Moreover, the predetermined filling amount can be easily changed by setting the supply filling amount of the granular material W by the control means 22 in accordance with the packaging specification of the packaged packaging bag P. As the setting condition, for example, the supply amount of the granular material W can be adjusted and set by setting the rotation speed, rotation speed, or rotation time of the servo motor which is the driving means 21.
[0054]

A motor 16 is provided. Further, a cylindrical supply opening 13 through which the granular material W is fed is provided at the lower end side of the hopper member 11, and the supply opening 13 side is connected to the lower side of the supply opening 13. A granular material transfer cylindrical member 19 in which a receiving portion 18 that is a granular material receiving port is formed is disposed sideways.
[0056]
In this case, the receiving part 18 that is a granular material receiving port is surrounded by a peripheral wall 30 so that the granular material W is not spilled from the supply opening 13 of the hopper member 11 to the outside.
[0057]
A peripheral wall 30 serving as a granular material receiving port formed by surrounding four sides constituting the receiving portion 18 is disposed on the cylindrical inner side of the granular material transfer cylindrical member 19 as shown in the figure. The wall portion 30A facing the rotation direction of the screw conveying blade 20A is installed at an acute angle so as to overhang on the opposite side to the rotation direction of the screw conveying blade 20A.
[0058]
Further, the wall portion 30B that constitutes a part of the peripheral wall 30 serving as the granular material receiving port opposite to the conveying direction of the granular material W by the rotational driving of the screw conveying blade 20A is opposite to the conveying direction of the granular material W. It is installed at an acute angle.
[0059]
In addition, a vibration generator 31A is provided on the outer side of the peripheral wall 30 serving as the granular material receiving port, and a vibration generator 31A that intermittently applies an impact to the granular material receiving side by the reciprocating operation of the piston by the cylinder. In this case, for example, when supplying the granular material W, an impact is applied to the outer side of the peripheral wall 30 serving as the granular material receiving port at a predetermined interval.
[0060]
In the second embodiment, a granular material outlet 23 is provided on the tip side wall portion of the granular material transfer cylindrical member 19 provided in the package filling mechanism 7, and the granular material outlet 23 is opened and closed. The valve member 24 is provided so as to be closed and closed. In this case, the on-off valve member 24 is attached depending on the nature of the granular material W, that is, the degree of opening of the granular material outlet 23 in accordance with the fluidity of the granular material W, or depending on the nature of the granular material W In a case where there is a slight amount of moisture, the granular material W is provided in an open state without attaching a plate-shaped on-off valve member 24 to the granular material outlet 23, and the granular material W is charged by only feeding the screw conveying blade 20A. It may be arranged to supply to the 29 side.
[0061]
Therefore, in the filling and packaging machine of the present invention having the above-described configuration, the bottom of the packaging bag P is formed by the side seal FS portion in the same manner as in the first embodiment described above, so that the package can be filled. The screw conveyor member in which the powder motor W stored in the hopper member 11 is disposed in the granular material transporting cylindrical member 19 by operating the servo motor which is the driving means 21 of the filling mechanism 7. It is fed out and guided in one direction by 20 rotational movements.
[0062]
Subsequently, the opening / closing valve member 24 that closes and closes the granular material carry-out port 23 by the pressing force of the granular material W is bent laterally with the upper side as a fulcrum, and the granular material carry-out port 23 is opened. By this opening operation, the granular material W is supplied from the front end side of the granular material transfer cylindrical member 19 to the filling portion of the packaging bag P through the charging chute 29.
[0063]
By the way, the granular material W stored inside the hopper member 11 is fed out from the supply opening 13 while being stirred by the screw feeder 14, and the fed granular material W is connected to the supply opening 13. The granular material W fed into the peripheral wall 30 serving as the granular material receiving port formed by surrounding the four sides constituting the receiving part 18 is spirally formed by the rotational operation of the screw conveyor member 20. With the rotation of the screw conveying blade 20A, the granular material W acts so as to be sent to the inside of the granular material transfer cylindrical member 19 via the receiving portion 18 serving as the granular material receiving port.
[0064]
That is, with the rotational drive of the screw conveying blade 20A, the wall portion 30A side of the receiving portion 18 serving as the granular material receiving port facing the rotation direction of the screw conveying blade 20A as the conveying blade 20A moves. The granular material W is transferred in the horizontal direction inside the granular material transfer cylindrical member 19 along the direction (feeding direction) of the spiral screw conveying blade 20A.
[0065]
At this time, in the same manner as in the first embodiment described above, the wall portion 30A of the receiving portion 18 which is a powder particle receiving port facing the rotation direction of the screw conveying blade 20A is over the opposite side to the rotation direction of the conveying blade 20A. Since it is installed at an acute angle in a hung state, the wall surface is slightly over even if the granular material W tries to adhere to the inner wall surface of the receiving portion 18 (peripheral wall 30 serving as the granular material receiving port) serving as the granular material receiving port. Since it is hung, it adheres somewhat, but does not accumulate, and is supplied and guided in one direction while the powder W is pushed by the screw conveying blade 20A, and the powder provided in the granular material transfer cylindrical member 19 The granular material W is sent out from the carry-out side of the granular material transfer cylindrical member 19 to the filling portion of the packaging bag P via the charging chute 29 via the body outlet 23 and supplied.
[0066]
Further, the wall 30B of the granular material receiving port facing the transfer direction of the granular material W by the rotational drive of the screw conveying blade 20A is installed at an acute angle on the opposite side to the transfer direction of the granular material W, thereby causing a spiral. When the granular material W is fed into the granular material transfer cylindrical member 19 through the receiving portion 18 which is the granular material receiving port in accordance with the rotational drive by the screw conveying blade 20A in the form of a powder, the granular material W The granular material W fed out by placing the wall portion 30B of the granular material receiving port opposite to the conveying direction of the particle at an acute angle opposite to the conveying direction of the granular material W is pushed toward the wall portion 30B. Since it is fed along the slope of the wall 30B when it is dropped, it falls without being deposited due to its own weight or the like, and is supplied in a stable state to the inside of the granular material transfer tubular member 19 This is a conventional problem. It is possible to prevent the occurrence of the bridge phenomenon by residual particle on the wall portion of the granules receiving port in advance.
[0067]
Further, by intermittently applying an impact from the outside of the peripheral wall 30 serving as the granular material receiving port by the vibration generating device 31A by the reciprocating operation of the piston, the peripheral wall 30 serving as the granular material receiving port, particularly the helical screw conveying blade. The granular material W adhering to the inner surface portions of the wall portions 30A and 30B that are easily adhered by the rotation operation of 20A can be dropped in advance by an impact by the vibration generator 31, and the wall portion of the granular material receiving port Coupled with the installation conditions depending on the attachment angles of 30A and 30B, it is possible to further suppress phenomena such as adhesion of the granular material W to the walls 30A and 30B and cross-linking.
[0068]
At this time, in substantially the same manner as in the first embodiment described above, the granular material W sent by the rotational operation of the helical screw conveying blade 20A was provided on the distal end side of the granular material transfer cylindrical member 19. When the powder is delivered to the position of the powder carry-out port 23, the pressure applied by the powder W or the pressure applied by the weight of the powder W itself generated when the screw conveyor member 20 is rotated is reduced. By adding to the on-off valve member 24 that closed and closed the granular material outlet 23, the on-off valve member 24 bends to open the granular material outlet 23, and by this opening, the granular material W becomes the granular material outlet 23. By flowing down from the gap, the pressure force of the granular material W applied to the on-off valve member 24 is eliminated, so that the on-off valve member 24 returns to its original state, and the rotational operation of the screw conveyor member 20 continues. During the duration, the pressure applied by the granular material W or the pressure due to the weight of the granular material W itself is applied to or reduced by the on-off valve member 24 closing and closing the granular material outlet 23. By repeating the state, the on-off valve member 24 is finely opened and closed, whereby the granular materials W are sequentially supplied.
[0069]
Accordingly, a predetermined amount of the granular material W is supplied into the packaging bag P by the opening / closing operation of the on-off valve member 24, and the pressure due to the rotational operation of the screw conveying blade 20A or the weight of the granular material W itself is applied. When the pressure no longer acts on the granular material outlet 23, the on-off valve member 24 closes and closes the granular material outlet 23 (blocking state), so that the granular material W falls down from the granular material outlet 23. As a result, it is possible to prevent the granular material W from being bitten into the packaging bag P when the portion that becomes the bottom of the packaging bag P is heat-sealed by the horizontal sealing mechanism 6, Heat sealing can be performed while keeping the state of the lateral seal FS good.
[0070]
