Abstract
Description
本発明は、パウチパックに対する流動性充填物の充填の有無を確認する方法及び装置に関する。 The present invention relates to a method and an apparatus for confirming whether or not a fluid packing is filled in a pouch pack.
液状乃至ゲル状若しくはクリーム状等の流動性化粧料や流動性洗剤、流動性調味料等の流動性充填物を充填してなるパウチパックは、今日、省資源、低価格等の観点から一般消費者の間にも浸透し、広く普及するに至っている。 Pouch packs filled with fluid cosmetics such as liquids, gels, or creams, fluid detergents, fluid seasonings, etc. are generally consumed today from the viewpoint of resource saving and low cost. It has also penetrated among people and has become widespread.
従来のパウチパックは、例えば、略方形状のフィルム二枚を重ね合わせ、その上辺部を除く周囲三方が略コ字形に熱シールされて袋状に形成された状態で、この上辺部の開口から流動性充填物が充填され、その後、前記開口が熱シールされることによって密閉される。このような熱シール工程及び充填工程は、例えば、特許文献１に記載されているように、従来、熱シールによる製包と充填を行う製包／充填装置によって、包装材の作製、即ち製包とその包装材への充填が一つの装置内で完結されるように構成されている。 A conventional pouch pack, for example, is formed by overlapping two substantially rectangular films and heat-sealing in a substantially U shape around the three sides excluding the upper side, forming a bag shape, and opening from the upper side opening. The fluid filling is filled and then the opening is sealed by heat sealing. For example, as described in Patent Document 1, such a heat sealing process and a filling process are conventionally performed by a packaging / filling apparatus that performs packaging and filling by heat sealing, that is, packaging. And filling of the packaging material is completed in one apparatus.
特許文献１の装置は、互いに逆回転するように近接的に併設された一対の側部熱シールローラと、これらの側部熱シールローラの間を通って、それらの下方まで延設された充填ノズルと、充填ノズルの先端の下方に回転軸を持って互いに逆回転するように近接的に併設された一対の上下部熱シールローラとを備える。特許文献１の装置による製包及び充填は、ロール状の二つのフィルム材から巻き出されたフィルム同士を、これらフィルム同士の間に充填ノズルを位置させて重ね合わせ、二つの側部熱シールローラの間に通して、これらのフィルムの左右両縁部を熱シールし、その下方に位置する上下部熱シールローラによって左右両縁部がシールされたフィルム材の下部を熱シールして上部が開口した略コ字形の半製状態の包装材に、充填ノズルから流動性充填物を所定量充填し、その後、上下部熱シールローラの回転に合わせて、充填が停止され、流動性充填物が充填されたフィルム材の上部が上下部熱シールローラによって熱シールされることによって、一包が完成されるように構成されている。 The device of Patent Document 1 includes a pair of side heat seal rollers that are arranged close to each other so as to rotate reversely, and a filling that extends between these side heat seal rollers and extends below them. A nozzle, and a pair of upper and lower heat seal rollers disposed adjacent to each other so as to rotate reversely to each other with a rotating shaft below the tip of the filling nozzle. The packaging and filling by the apparatus of Patent Document 1 are performed by superimposing films unwound from two roll-shaped film materials with a filling nozzle positioned between the two films, and two side heat sealing rollers. The left and right edges of these films are heat-sealed, and the lower part of the film material whose left and right edges are sealed by the upper and lower heat-sealing rollers located below is heat-sealed and the upper part is opened. The semi-finished packaging material in a substantially U-shape is filled with a predetermined amount of fluid filler from a filling nozzle, and then filling is stopped and fluid filler is filled in accordance with the rotation of the upper and lower heat seal rollers. The upper part of the formed film material is heat-sealed by the upper and lower heat seal rollers, so that one package is completed.
従来の製包／充填装置は、パウチパックを連続的に製造出来る上、製包と共に各パウチパックに流動性充填物を充填し、且つ密閉することが出来るため、生産効率が高く、今日のパウチパックの生産手段として欠かせない物となっている。ところが、従来この種の製包／充填装置を用いたパウチパックの製包／充填工程では、パウチパックに正常に流動性充填物が充填されず、空の状態で密閉されてしまう所謂空充填品が出来てしまうという問題がある。 Conventional packaging / filling devices can produce pouch packs continuously, and each pouch pack can be filled with a fluid filler and sealed together with the packaging. It is an indispensable means for producing packs. However, in the conventional packaging / filling process of a pouch pack using this type of packaging / filling device, the so-called empty-filled product in which the pouch pack is not normally filled with a fluid filler and is sealed in an empty state. There is a problem that can be made.
この空充填の発生は、作業者が誤って空充填品を正常品として扱ってしまったり、充填ノズルに流動性充填物を供給する供給元の流動性充填物が空になっていることに気が付かないなどといった人的要因によるものや充填ノズルに流動性充填物を供給する供給手段等の故障や動作不良といった機械的要因の他、高粘性の流動性充填物などにおいては、流動性充填物の供給手段上において流動性充填物に空気等のガスが混入し、これによって空充填が発生するといった流動性充填物的要因等によるものがある。 This empty filling occurs when an operator mistakenly handles an empty filling product as a normal product, or notices that the fluid filling material of the supplier supplying the fluid filling material to the filling nozzle is empty. In addition to mechanical factors such as failure due to human factors such as the absence or malfunction of the supply means for supplying the fluid filler to the filling nozzle and malfunction, fluid fillers with high viscosity There is a fluid filler-like factor in which a gas such as air is mixed into the fluid filler on the supply means, thereby causing empty filling.
このような空充填の検出を行うため、従来は、特許文献２に開示されているように、パウチパックの重量測定を行って空充填品の検出や選別を行う重量選別手段を用いたり、或いは、レーザー寸法測定器や超音波測定器等を利用してパウチパックの厚みを計測して空充填品の検出や選別を行う品厚選別手段を用いたり、透過型センサーを利用してパウチパックの内部に収容された流動性充填物の有無を直接観測して空充填品の検出や選別を行う透過選別手段を用いたものが検討されてきた。
ところが、重量選別手段では、小さくて軽い製品の場合には上手く検出できず、空充填品であっても検出されずに正常品として扱われてしまうことがあり、品厚選別手段では、薄手の製品の場合には上手く検出できず、空充填品であっても検出されずに正常品として扱われてしまうことがあり、透過選別手段ではアルミパウチ等のような不透明のパウチパックの場合には、用いることが出来ないという問題があった。 However, the weight sorting means cannot detect well in the case of a small and light product, and even an empty filling product may be detected as a normal product without being detected. In the case of a product, it cannot be detected well, and even an empty filling product may be detected as a normal product without being detected.In the case of an opaque pouch pack such as an aluminum pouch, etc. There was a problem that it could not be used.
本発明は、上記問題点に鑑みてなされたものであり、軽薄不透明なパウチパックであっても空充填品を高精度に検出することが出来るパウチパックにおける充填物の確認方法及び確認装置を提供せんとするものである。 The present invention has been made in view of the above problems, and provides a confirmation method and a confirmation device for a filling material in a pouch pack that can detect an empty filling product even with a light and opaque pouch pack. It is something to be done.
上記課題を解決するために本発明のパウチパックの充填物の確認方法において採った手段は、パウチパック内部に流動性充填物を充填しパウチパックを製包する工程において、流動性充填物をパウチパックに充填した後に、放射温度計測手段を用いてパウチパックの外表面の温度を計測し、該パウチパックの外表面の温度によって充填物の有無を判定することを特徴とする。 In order to solve the above-mentioned problem, the means employed in the method for confirming the filling of the pouch pack according to the present invention is the step of filling the pouch pack with the flowable filling and packaging the pouch pack. After filling the pack, the temperature of the outer surface of the pouch pack is measured using a radiation temperature measuring means, and the presence or absence of the filler is determined by the temperature of the outer surface of the pouch pack.
熱放射温度計測手段によるパウチパックの外表面における温度計測部位が、パウチパックの外表面の中心部であることを特徴とする。 The temperature measurement site on the outer surface of the pouch pack by the thermal radiation temperature measuring means is the center of the outer surface of the pouch pack.
計測された温度による充填物の有無の判定は、計測された温度が特定の設定温度以下の場合には充填物有りとし、計測された温度が前記設定温度よりも一定温度以上高い場合には充填物無しとするものであることを特徴とする。 The determination of the presence or absence of a filler based on the measured temperature is determined to be that there is a filler when the measured temperature is equal to or lower than a specific set temperature, and filling is performed when the measured temperature is higher than the set temperature by a certain temperature or more. It is characterized by nothing.
計測された温度が、設定温度よりも１０℃以上高い場合には充填物無しと判定し、設定温度以下である場合には充填物有りと判定するようにしたことを特徴とする。 When the measured temperature is higher than the set temperature by 10 ° C. or more, it is determined that there is no filler, and when it is equal to or lower than the set temperature, it is determined that there is a filler.
パウチパックが複数個連なる製包工程において、その連続しているパウチパックの或一つのパウチパックが充填物無しと判定された場合には、充填物無しと判定されたパウチパックの前後一包ずつが、当該充填物無しのパウチパックから切り離されず、連包状態で繰り出されることを特徴とする。 In a packaging process in which a plurality of pouch packs are connected, if one pouch pack of the continuous pouch packs is determined to have no filling, one pack before and after each pouch pack determined to have no filling However, it is not cut off from the pouch pack without the filling but is fed out in a bundled state.
また、本発明のパウチパックの充填物の確認装置において採った手段は、パウチパックの外表面の温度を計測する放射温度計測手段と、この放射温度計測手段によって計測された温度と予め設定された設定温度とを比較して充填物の有無を判定する判定処理部とを備え、放射温度計測手段の配設位置が、パウチパック包装装置の熱シール工程位置よりも後の工程位置で、且、パウチパックに流動性充填物を充填するための充填ノズルの工程位置よりも後の工程位置に配置されていることを特徴とする。 Further, the means adopted in the pouch pack filling confirmation device of the present invention is a radiation temperature measuring means for measuring the temperature of the outer surface of the pouch pack, and a temperature measured by the radiation temperature measuring means is preset. A determination processing unit that compares the set temperature and determines the presence or absence of a filler, and the location of the radiation temperature measuring means is a process position after the heat sealing process position of the pouch pack packaging device, and It is arranged at a process position after the process position of the filling nozzle for filling the pouch pack with the fluid filler.
また、充填物の有無の判定結果に対応して、連包状態のパウチパックを切り離すための切断手段の作動制御を行うように構成されることを特徴とする。 Moreover, it is comprised so that the action | operation control of the cutting | disconnection means for cut | disconnecting the pouch pack of a continuous package state may be performed according to the determination result of the presence or absence of a filling.
本発明は、パウチパックに対する流動性充填物の有無を確認する手段として、パウチパックの外表面の中心部の温度を、充填と製包の後に、熱放射温度計測手段によって計測し、予め設定された正常温度の上限値との比較上、計測された温度が、設定温度よりも１０℃以上高い場合には充填物無しと判定し、設定温度以下である場合には充填物有りと判定するようにして空充填の判定を行うようにしたので、軽薄不透明なパウチパックであっても空充填品を高精度に検出することが出来る。 In the present invention, as a means for confirming the presence or absence of a fluid filling material for the pouch pack, the temperature of the central portion of the outer surface of the pouch pack is measured by a thermal radiation temperature measuring means after filling and packaging, and is set in advance. In comparison with the upper limit of the normal temperature, if the measured temperature is 10 ° C. or more higher than the set temperature, it is determined that there is no filler, and if it is lower than the set temperature, it is determined that there is a filler. Thus, the determination of empty filling is performed, so that even a light and opaque pouch pack can detect an empty filling product with high accuracy.
また、充填物の有無を判定する判定処理部の判定結果に対応させて、連包状のパウチパック同士を切り離す切断手段の作動制御を行うように構成し、或一包が空充填品と判定された場合にはその前後一包ずつを切断せずに連包状態として繰り出すようにしたことによって、見た目にも明らかに空充填品であることが判断でき、効率的に空充填品を排除することが出来る。 In addition, in accordance with the determination result of the determination processing unit for determining the presence or absence of the filling, it is configured to control the operation of the cutting means for separating the continuous pouch packs, or one package is determined to be an empty filling product In this case, it is possible to judge that it is clearly an empty filling product by removing it as a continuous packaging state without cutting the front and back of each package, and efficiently eliminating the empty filling product. I can do it.
本発明の実施の形態を、以下に添付図面（図１〜３）を参照しながら詳細に説明する。本実施態様のパウチパック(１)の充填物の確認装置(10)は、ロール状に巻回された二つのフィルム材(2a)(2b)を、熱シールして連包状に半製包しつつ、半製包状の各パウチパック(１)に、流動性充填物(図示省略)を充填し、その後、密封して製包を完成させ、次いで、パウチパック(１)が縦横に連なっている縦横連包体(３)を切断して個々のパウチパック(１)に切り離す製包装置(20)／充填装置／切断装置(40)に併設されるものである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings (FIGS. 1 to 3). The packing confirmation device (10) of the pouch pack (1) of this embodiment is a semi-wrapping in a continuous form by heat-sealing two film materials (2a) and (2b) wound in a roll shape.

本実施態様のパウチパック(１)の充填物の確認装置(10)は、製包装置(20)の横シールローラ(22a)(22b)の下方に配設される放射温度計(11a)(11b)(11c)と、これらの放射温度計(11a)(11b)(11c)によって計測された計測温度と、予め設定された設定温度とを比較して充填物の有無を判定する判定処理部と、放射温度計(11a)(11b)(11c)を配設するための架台(12)とを備える。放射温度計(11a)(11b)(11c)は、物体の表面温度をその物体から放射される赤外線等を捉えることによって表面温度を計測するように構成された物であればよく、従来公知の物を採用することが出来る。この放射温度計(11a)(11b)(11c)は、一列のパウチパック(１)に放射温度計(11a)(11b)(11c)一台が対応するように配設される。 The filling confirmation device (10) of the pouch pack (1) of this embodiment is a radiation thermometer (11a) (11a) disposed below the horizontal sealing rollers (22a) (22b) of the packaging device (20). 11b) (11c) and a determination processing unit that determines the presence or absence of a filler by comparing the measured temperature measured by these radiation thermometers (11a), (11b), and (11c) with a preset set temperature. And a gantry (12) for disposing the radiation thermometers (11a), (11b), and (11c). The radiation thermometers (11a), (11b), and (11c) may be any object that is configured to measure the surface temperature by capturing the surface temperature of the object by capturing infrared rays or the like emitted from the object. Things can be adopted. The radiation thermometers (11a), (11b), and (11c) are arranged so that one radiation thermometer (11a), (11b), and (11c) corresponds to one row of pouch packs (1).
これらの放射温度計(11a)(11b)(11c)は、各放射温度計(11a)(11b)(11c)が横シールローラ(22a)(22b)の下方に位置するように架設された架台(12)に固定され、幅方向に一列に配設される。判定処理部は、各パウチパック(１)の外表面の中心部の温度を測温するように、縦横連包体(３)の繰り出し速度に対応させ、各パウチパック(１)の外表面の中心部が測温位置となるタイミングに同期させて測温するように、放射温度計(11a)(11b)(11c)の作動制御を行うように構成される。また、判定処理部は、放射温度計(11a)(11b)(11c)による計測温度と予め設定された設定温度とを比較し、計測温度が設定温度よりも１０℃以上高温となった場合に、そのパウチパック(１)を充填物無しと判定し、計測温度が設定温度以下である場合には充填物有りと判定するように構成される。また、判定処理部は、充填物無しと判定が出た場合に、切断装置(40)の横方向切断手段の作動を一定量停止するように制御するように構成される。即ち、充填物無しと判定された場合には、切断装置(40)から繰り出されるパウチパック(１)は、充填物無しと判定された生産ラインだけ、縦方向にパウチパック(１)が幾つか連なった連包状のものとなる。 These radiation thermometers (11a), (11b), and (11c) are mounted on the base so that each of the radiation thermometers (11a), (11b), and (11c) is positioned below the horizontal seal rollers (22a) and (22b). It is fixed to (12) and arranged in a line in the width direction. The determination processing unit corresponds to the feeding speed of the vertical and horizontal continuous bodies (3) so as to measure the temperature of the center part of the outer surface of each pouch pack (1), and the outer surface of each pouch pack (1). The radiation thermometers (11a), (11b), and (11c) are configured to perform operation control so that the temperature is measured in synchronism with the timing at which the central portion becomes the temperature measurement position. In addition, the determination processing unit compares the temperature measured by the radiation thermometer (11a) (11b) (11c) with a preset temperature, and when the measured temperature is higher than the set temperature by 10 ° C or more. The pouch pack (1) is determined as having no filling, and when the measured temperature is equal to or lower than the set temperature, it is determined that there is a filling. The determination processing unit is configured to control the operation of the lateral cutting means of the cutting device (40) to be stopped by a certain amount when it is determined that there is no filler. That is, when it is determined that there is no filling, the pouch pack (1) fed out from the cutting device (40) has several pouch packs (1) in the vertical direction only for the production line determined as having no filling. It becomes a continuous package.
本実施態様のパウチパック(１)の充填物の確認装置(10)は、以上説明したように構成され、上記製包装置(20)／充填装置／切断装置(40)上におけるその確認方法は、先ず、ロール状に巻回された二つフィルム材(2a)(2b)が、繰り出し可能に、製包装置(20)の縦シールローラ(21a)(21b)の上方から巻き出され、二つの縦シールローラ(21a)(21b)間に通される。このとき、充填装置の充填ノズル(30a)(30b)(30c)がフィルム材(2a)(2b)の間に位置するように設定される。更に、下方に繰り出されるフィルム材(2a)(2b)は、縦シールローラ(21a)(21b)を通過する際に、適宜間隔をもってフィルム材(2a)(2b)の長手方向に連なる四つの帯状の熱シール部(４)(４)(４)(４) が形成され、二枚のフィルム材(2a)(2b)同士が縦方向に熱シールされる。 The filling confirmation device (10) of the pouch pack (1) of the present embodiment is configured as described above, and its confirmation method on the packaging device (20) / filling device / cutting device (40) is as follows. First, the two film materials (2a) and (2b) wound in a roll shape are unwound from above the vertical seal rollers (21a) and (21b) of the packaging apparatus (20) so as to be fed out. Passed between the two vertical sealing rollers (21a) (21b). At this time, the filling nozzles (30a), (30b), and (30c) of the filling device are set so as to be positioned between the film materials (2a) and (2b). Further, the film material (2a) and (2b) fed downward are four strips continuous in the longitudinal direction of the film material (2a) and (2b) at an appropriate interval when passing through the vertical seal rollers (21a) and (21b). The heat seal portions (4), (4), (4) and (4) are formed, and the two film materials (2a) and (2b) are heat sealed in the longitudinal direction.
更に、下方に繰り出されたフィルム材(2a)(2b)は、横シールローラ(22a)(22b)のシール部(28a)(28b)によって、横方向の熱シール部(５)が形成され、二枚のフィルム材(2a)(2b)同士が横方向に熱シールされる。この状態で、充填ノズル(30a)(30b)(30c)先端から流動性充填物が、各半製包状態のパウチパック(１)の内部に充填される。充填されながら更に下方に繰り出されたフィルム材(2a)(2b)は、横シールローラ(22a)(22b)の他方のシール部(28a)(28b)によって、横方向の熱シール部(５)が形成され、各半製包状態であったパウチパック(１)の上方の開口が閉じられ、密閉されて製包されたパウチパック(１)が得られる。但しこの時点では、各パウチパック(１)は、縦方向においても横方向においても連包状態となっている。 Further, the film material (2a) (2b) fed downward is formed with a horizontal heat seal portion (5) by the seal portions (28a) (28b) of the horizontal seal rollers (22a) (22b), The two film materials (2a) and (2b) are heat-sealed in the lateral direction. In this state, the fluid filler is filled from the tip of the filling nozzles (30a), (30b), and (30c) into each semi-wrapped pouch pack (1). The film material (2a) (2b) which is further drawn out while being filled is transferred to the transverse heat seal portion (5) by the other seal portions (28a) (28b) of the transverse seal rollers (22a) (22b). And the upper opening of each pouch pack (1) that has been in a semi-wrapped state is closed to obtain a sealed and wrapped pouch pack (1). However, at this time, each pouch pack (1) is in a bundled state both in the vertical direction and in the horizontal direction.
縦横連包体(３)は、更に下方に繰り出され、横シールローラ(22a)(22b)の下方に位置する熱放射温度計(11a)(11b)(11c)によって、各パウチパック(１)の外表面の中心部の温度が計測される。この計測は、判定処理部によって計測タイミングが制御されるものであり、パウチパック(１)の外表面の中心部が放射温度計(11a)(11b)(11c)の測温領域に一致するタイミングで計測されるように構成される。計測された計測温度は、直ちに、充填物の確認装置(10)の判定処理部において、予め設定された設定温度と比較される。ここで、設定温度とは、パウチパック(１)に充填される流動性充填物やパウチパック(１)を構成する素材やサイズ、フィルム材(2a)(2b)の繰り出し速度等によって決定されるものであり、概ね３６℃から５８℃以下に設定される。 The vertical / horizontal continuous package (3) is further drawn downward, and each pouch pack (1) is provided by thermal radiation thermometers (11a), (11b), and (11c) positioned below the horizontal seal rollers (22a) and (22b). The temperature at the center of the outer surface of the is measured. In this measurement, the determination processing unit controls the measurement timing, and the timing when the central portion of the outer surface of the pouch pack (1) coincides with the temperature measurement region of the radiation thermometer (11a) (11b) (11c). It is comprised so that it may be measured by. The measured temperature is immediately compared with a preset temperature in the determination processing unit of the filling confirmation device (10). Here, the set temperature is determined by the flowable filling material filled in the pouch pack (1), the material and size constituting the pouch pack (1), the feeding speed of the film materials (2a) and (2b), and the like. The temperature is generally set to 36 ° C. to 58 ° C. or less.
設定温度と計測温度との比較は、計測温度から設定温度を差し引いた際の温度差を求めるものであり、設定温度よりも１０℃以上高い場合には充填物無しと判定し、設定温度以下である場合には充填物有りと判定するようにして空充填の判定を行うようにしている。勿論、この温度差は、パウチパック(１)に充填される流動性充填物やパウチパック(１)を構成する素材やサイズ、フィルム材(2a)(2b)の繰り出し速度等によって決定されるものである。 The comparison between the set temperature and the measured temperature is to obtain the temperature difference when the set temperature is subtracted from the measured temperature. If the set temperature is higher than the set temperature by 10 ° C or more, it is determined that there is no filling, and below the set temperature. In some cases, it is determined that there is a filling, and the determination of empty filling is performed. Of course, this temperature difference is determined by the fluid filling material to be filled in the pouch pack (1), the material and size of the pouch pack (1), the feeding speed of the film materials (2a) and (2b), etc. It is.
充填物の確認装置(10)による確認結果が正常、即ち充填物有りと判定されている間は、滞りなく以上の工程を経て、縦横連包体(３)をなすパウチパック(１)は更に下方の切断装置(40)に送られる。切断装置(40)では、縦方向の切断を行う縦方向切断手段によって、縦横連包体(３)の縦方向の熱シール部(４) の中央部を切断すると共に、横方向切断手段によって、縦横連包体(３)の横方向の熱シール部(５)の中央部を切断し、縦横連包体(３)から各パウチパック(１)が切り離される。この切り離した状態を図１に示してある。 While the confirmation result by the filling confirmation device (10) is normal, that is, it is determined that there is a filling, the pouch pack (1) forming the vertical and horizontal continuous package (3) is further processed through the above steps without delay. Sent to the lower cutting device (40). In the cutting device (40), the vertical cutting means for cutting in the vertical direction cuts the center of the vertical heat seal portion (4) of the vertical and horizontal continuous package (3), and the horizontal cutting means The center part of the heat seal part (5) of the horizontal direction of a vertical / horizontal continuous package (3) is cut | disconnected, and each pouch pack (1) is cut off from the vertical / horizontal continuous package (3). This disconnected state is shown in FIG.
仮に、図１に示す充填物の確認装置(10)における左端に位置する放射温度計(11a)によって一包分だけ空充填が検出されると、判定処理部が作動して切断装置(40)における左端の横方向切断手段が制御され、空充填の一包(６)部分が繰り出されて来るタイミングに同期して、その一包(６)の前後一包(７)(８)ずつを空充填の一包(６)から切断せず、切断を見送るように構成される。つまり、この場合の空充填の一包(６)は、図３に示すように、上下に一包(７)(８)ずつが連なった三連包体(９)となって切断装置(40)から繰り出される。このように、三連包体(９)で繰り出されることにより、作業者は空充填の一包(６)を容易に判定することができ、三連包体(９)の先端の一包(７)と後端の一包(８)を切り離して、中央部分の空充填の一包(６)を容易に取り除くことが出来る。なお、連包数は、任意に設定可能であることは言うまでもない。
If the
空充填が発生した列以外の縦横連包体(３)は、通常通り、縦と横の熱シール部(４)、(５)が切断され一つ一つの独立したパウチパック(１)となる。尚、一生産ライン上において二包連続で、空充填が検出された場合には、その二包の上下の一包ずつが連なった四連包体となって切断装置(40)から繰り出されるように設定される。更に、三包連続で空充填品と判定された際などには、警告を発すると共に、製包装置(20)／充填装置／確認装置(10)／切断装置(40)の装置全体の作動を停止するように設定することもできる。 As usual, the vertical and horizontal continuous packages (3) other than the rows where empty filling has occurred are cut into vertical and horizontal heat sealing portions (4) and (5) to form individual pouch packs (1). . In addition, when empty filling is detected continuously in two packages on one production line, it is drawn out from the cutting device (40) as a four-packed package in which the upper and lower packages of the two packages are connected. Set to Furthermore, when it is determined that three packages are continuously empty, a warning is issued and the overall operation of the packaging device (20) / filling device / checking device (10) / cutting device (40) is activated. It can also be set to stop.
以上説明したように、本発明のパウチパック(１)の充填物の確認方法及び確認装置(10)は、パウチパック(１)の製包装置(20)／充填装置／切断装置(40)に併設され、充填／製包後に、パウチパック(１)の外表面の温度を熱放射温度計(11a)(11b)(11c)によって計測し、その計測温度と予め設定される設定温度との温度の比較によって充填物の有無を判定すると共に、この判定結果に基づいて、切断装置(40)を制御するように構成したものであって、その主旨を逸脱しない範囲において様々な形態で実施することができる。 As described above, the pouch pack (1) filling confirmation method and confirmation device (10) according to the present invention is the same as the pouch pack (1) packaging device (20) / filling device / cutting device (40). After filling / packaging, the temperature of the outer surface of the pouch pack (1) is measured by the thermal radiation thermometers (11a), (11b), and (11c), and the temperature between the measured temperature and a preset set temperature. It is configured to determine the presence or absence of a filler by comparison of the above, and to control the cutting device (40) based on the determination result, and in various forms without departing from the gist thereof Can do.
以下に、本実施態様において説明したように構成された製包／充填／確認／切断の各装置を用いて、以下の通り実験した結果を示す。この実験の目的は、パウチパックの生産ライン上で、各パウチパックの外表面の中心部の温度を放射温度計で計測することによって充填物の有無を検出することが出来るか否かを検証するものであり、また充填の有無の判定結果が、パウチパックに充填される流動性充填物やパウチパックの素材やサイズ、或いは、フィルム材の繰り出し速度、即ちパウチパックの生産速度にどの程度影響を受けるのかを定量的に検証するものである。 The results of experiments as follows using each of the packaging / filling / confirmation / cutting apparatuses configured as described in the present embodiment will be shown below. The purpose of this experiment is to verify whether the presence or absence of a filler can be detected by measuring the temperature at the center of the outer surface of each pouch pack with a radiation thermometer on the production line of the pouch pack. In addition, the determination result of whether or not filling has an effect on the flowable filling material and the material and size of the pouch pack or the feeding speed of the film material, that is, the production speed of the pouch pack. This is a quantitative verification of whether or not it is received.
実験は、流動性充填物として、化粧水、乳液、洗顔フォーム、クリームを使用した。フィルム材は、シーラント層をポリエチレン、ポリエチレンテレフタレートとした。パウチパックのサイズは、４０×４０ｍｍ、５０×８０ｍｍとした。生産速度は、３０包／分、５０包／分、８０包／分とした。このように各種実験を設定し、充填物有りのパウチパック（以下、充填品と呼ぶ。）と充填物無しのパウチパック（以下、空充填品と呼ぶ。）とのそれぞれの外表面の中心部の温度を放射温度計によって計測し、充填品と空充填品との温度差を算出した。これらの実験結果をまとめたものを表１に示す。
表１から明らかな通り、各種テスト条件の結果からは、充填品の温度が３３〜５８℃であるのに対して、空充填品はそれらの温度より１７〜４０℃高くなっていて、容易に充填品と空充填品の判定が出来ることが判る。 As is clear from Table 1, from the results of various test conditions, the temperature of the filled product is 33 to 58 ° C., whereas the empty product is 17 to 40 ° C. higher than those temperatures. It can be seen that it is possible to determine whether the product is filled or empty.
このような結果、即ち充填品と空充填品とで、それらの外表面の中心部の温度として表１に示すような有意の温度差が得られるのは、充填された後にそのパウチパックの上縁の開口を熱シールして密閉した際に、流動性充填物が充填されている場合には、熱容量が大きくなってパウチパックの外表面の中心に熱が伝達されるのが弱く遅くなるのに対して、空充填品の場合には、上縁の開口を熱シールしたときの残熱が、吸収される熱容量物質が殆ど無いために、強く早くパウチパックの外表面の中心部に伝達されるという違いがあることによるものと考えられる。 Such a result, that is, a significant temperature difference as shown in Table 1 as the temperature at the center of the outer surface between the filled product and the empty-filled product is obtained after the pouch pack is filled. When the edge opening is heat-sealed and sealed, if it is filled with a fluid filler, the heat capacity increases and the heat transfer to the center of the outer surface of the pouch pack is weak and slow. On the other hand, in the case of an empty-filled product, the residual heat when the upper edge opening is heat-sealed is transmitted to the center of the outer surface of the pouch pack strongly and quickly because almost no heat capacity material is absorbed. This is probably due to the difference.
