This spouted bouch reduces the air content to a predetermined amount to prevent bag breakage due to falling while the contents are filled, and is a low-acid food or product that requires retort sterilization. In order to ensure perfect sealing of beverages, inner seal material such as aluminum foil is applied to the spout mouth and sealed. In addition, the inner seal material is protected by a cap, and its sealing performance is ensured. The spout mouth is sealed with the inner seal material by temporarily sealing the inner seal material to the spout mouth portion of the spout with the contents filled, and the temporarily sealed inner seal material. The process of removing unnecessary portions and the primary sealing process and the secondary sealing process for completely sealing the inner seal material temporarily sealed in the spout opening are performed.
上記したィンナーシール材によるスパゥ ト口部の密封は、ィンナーシ 一ル材を仮シールする工程の善し悪しにより、スパゥ ト付パゥチ内の含 気量の調整不全や空気の吸込現象が発生して、その後の工程に大きな影 響を及ぼし、 最終的にはスパゥト付バウチの内容物の品質に影響し、且つ 含気量の増加により外部衝撃の緩衝力の低下をきたすことになる。 この ような状況から、スパゥ ト口部にィンナーシール材を仮シールする方法 を改善したものとして、以下のようなものが提案されている。 Sealing of the spout mouth with the inner seal material described above may result in improper adjustment of the air content in the spout pouch or air suction due to the quality of the temporary seal of the inner seal material. A big shadow on the process It will affect the quality of the contents of the spouted vouch, and the buffering capacity of external impact will be reduced by increasing the air content. Under these circumstances, the following has been proposed as an improved method of temporarily sealing the inner seal material at the spout opening.

[発明が解決しようとする課題]  [Problems to be solved by the invention]
しかしながら、上記先行文献 1のインナーシール材によるスパゥトロ部の密 封では、スパゥト口部にィンナーシ一ル材を完全シールするまで、 スパゥト付パ ゥチを規制部材に収容し続けなければならず、各工程が複雑になり余分な規制 部材も装備しなければならない不都合さがある。  However, in the sealing of the spout portion with the inner seal material of the above-mentioned prior art document 1, the spouted pouch must be accommodated in the regulating member until the inner seal material is completely sealed in the spout mouth portion. There is a disadvantage that the process becomes complicated and an extra restriction member must be provided.
また、 上記先行文献 2のインナーシール材によるスパゥトロ部の密封では、部 分的に仮シールしているので、スパゥト付パゥチの側面を脱気板により押圧し ても、 次のインナーシ一ル材の完全シール工程にスパゥト付バウチを移動する 際に、自重によりスパゥト付バウチ下部が膨らみ、 それに連れて若干空気を吸い 込んでしまうことになり、含気量の調整不全や空気の吸込現象を規制すること が困難な状況となる。  In addition, in the sealing of the spout portion with the inner seal material of the above-mentioned prior art document 2, since the temporary seal is partially performed, even if the side surface of the pouch with a spout is pressed by the deaeration plate, the next inner seal material When moving the spout with a spout during the complete sealing process, the lower part of the spout with a spout swells due to its own weight, and as a result, a little air is sucked in, which regulates the adjustment of air content and the phenomenon of air suction. This is a difficult situation.
また、 上記先行文献 3の充填密封装置を用いる密封は、スパゥトロ部にインナ 一シール材を仮シールする際、 仮シールバーでスパゥトロ部全面を均一に押圧 できるように調整できる点で優れているが、 全周シールが出来るようにシール へッドとスパゥトロ部上端部の平行度を調整するという手段はかなりの時間が かかる作業が要求される。  In addition, the sealing using the filling and sealing device of the above-mentioned prior art document 3 is excellent in that it can be adjusted so that the entire surface of the supertro part can be uniformly pressed with a temporary seal bar when temporarily sealing the inner sealing material to the supertro part. The method of adjusting the parallelism of the seal head and the upper end of the supertro part so that all-round sealing can be performed requires work that requires a considerable amount of time.
その結果、 仮の全周シールが出来ないことになつて、シール工程にスパゥト付 バウチを移動する際、 上記先行文献 2と同様に若干の空気を吸い込んでしまう 虞があり、含気量の調整不全や空気の吸込現象を規制することが困難な状況と なる虞がある。 そこで本発明の目的は、 工程を複雑にすることなく、余分な規制部材を不必要 とし、 スパゥト付バウチ内の含気量を調整してその状態を保持でき、且つ空気の 吸込現象も規制することが出来るィンナーシール材の仮シール方法およびその 方法を提供することにある。 As a result, there is a possibility that a slight amount of air may be inhaled when moving the spouted bouch in the sealing process, as in the case of the above-mentioned prior art document 2. There is a risk that it will be difficult to regulate the failure and the phenomenon of air suction. Therefore, an object of the present invention is to eliminate the need for an extra regulating member without complicating the process, to adjust the air content in the spouted bouch and maintain the state, and to regulate the air suction phenomenon. It is an object of the present invention to provide a temporary sealing method for an inner seal material and a method for the same.

[発明を実施するための最良の形態] [Best Mode for Carrying Out the Invention]
以下に、 図面を参照して本発明を実施するための最良の形態を説明する。 ぐ実施形態 1 >  The best mode for carrying out the present invention will be described below with reference to the drawings. Embodiment 1>
図において、 Aはスパゥト付バウチ充填機を示し、 このスパゥト付パゥチ充 填機 Aは、 以下のような工程を経て、 スパゥト付バウチ内に内容物を充填し、 密封するものである。 1はスパゥト付パゥチ 2 0の供給工程であり、 この供給 工程 1にて、保持部材 2 1にスパゥト付バウチ 2 0を吊り下げ保持する。次に、 印字'印字検查工程 2にて、 必要事項がスパゥト付バウチに印字され、 その印 字が正しくなされているかを検査する。  In the figure, A indicates a spouted pouch filling machine, and this spouted pouch filling machine A is filled with the contents in the spouted pouch through the following process and sealed.

次の予備開口 ·プレ置換工程 3にてスパゥト付バウチ 2 0内の空気を一度バ キュームポンプ等で除去した後に窒素を吹き込みバウチ内の空気を窒素で置換 すると共に、 内容物の充填前にバウチを膨らませることでバウチの開口性を向 上させている。 次の脱気 ·充填工程 4にて、 充填時の泡立ちを低減する目的で スパゥト付バウチ 2 0内のエアー脱気板でエアーを除去した後に内容物を充填 する。バウチ内の脱気は必ずしも脱気板の押圧によるものでなくとも、例えば、 棒状のものであっても脱気の目的が達成できるものであればよい。  Next preliminary opening · In the pre-replacement step 3, the spouted bout 20 is once removed with a vacuum pump, etc., and then nitrogen is blown in to replace the air in the bouch with nitrogen and before filling the contents. The opening of the bouch is improved by inflating. In the next degassing / filling step 4, the air is removed with the air degassing plate in the spouted bouch 20 for the purpose of reducing foaming during filling, and then the contents are filled. The deaeration in the bouch is not necessarily due to the pressing of the deaeration plate. For example, it may be a rod-like one as long as the purpose of deaeration can be achieved.
次の口部洗浄 ·窒素置換工程 5にて、 スパゥト付バウチ 2 0のスパゥト口部 2 2外側を洗浄し、 且つスパゥト付バウチ 2 0の内容物上に溜まっているエア 一を不活性ガスの窒素により置換する。 次の口部エア一乾燥 ·窒素置換工程 6 にて、 スパゥトロ部 2 2の外側をエアー乾燥し、 さらに窒素置換を繰り返して バウチ内の酸素量を低減させる。  In the next mouth cleaning and nitrogen replacement step 5, the outside of the spout mouth part 2 2 of the spout bouch 20 is washed, and the air accumulated on the contents of the spout bouch 20 is removed with inert gas. Replace with nitrogen. In the next mouth air-drying / nitrogen replacement step 6, the outside of the super-portion 22 is air-dried, and further nitrogen replacement is repeated to reduce the amount of oxygen in the bouch.

Adjust the air content. After the deaeration, temporary sealing of the inner seal material 2 3, which will be described in detail later, is performed on the supertro section 2 2, and the necessary inner seal material 2 3 is punched out. In the next first sealing step 8 and second sealing step 9, the inner sealing material 23 is sufficiently heated at the opening end of the super-portion 22 and fully sealed to be completely sealed. In the next seal cooling step 10, the heated inner seal material 2 3 is cooled. In the next inner seal inspection process 1 1, check the seal condition. In the next cap tightening step 1 2, the cap 2 4 is screwed onto the supertro part 2 2. In the next cap inspection process 1 3, the screwed state of the cap 2 4 is detected. Next product take-out process 14 Normal product 25 is taken out from pouch filling machine A with spout in 4 and then defective product in each inspection process 2 5 in the next defective product discharge process 1 5 Is discharged.
次に、 脱気 ·仮シール ·打ち抜き工程 7における仮シール手段について詳述 する。  Next, the temporary sealing means in the degassing / temporary sealing / punching step 7 will be described in detail.
まず、 インナーシール材の仮シール装置 3 0によりスパゥト付バウチ 2 0の スパゥトロ部 2 2上にィンナーシール材 2 3が仮シールされる。 この仮シール 装置 3 0は先端が外方に凸形状に形成されてなるシールバー 3 2を有する仮シ ール機構 3 1と、 仮シール時に内容物を充填した状態のスパゥト付バウチ 2 0 における内容物面 2 7より上に位置するバウチ部位 2 0 aを押圧する脱気板機 構 3 4 (第 3図及び第 4図参照） と、 を少なくとも具備してなる。 シールはシ 一ルバ一の加熱によるのが最も適した方法であるが、 例えば、 弱接着性の糊材 による貼付であっても、 シール材を加圧することによる貼付であってもよレ、。 前記仮シール機構 3 1は、 上記のシールバー 3 2と、 このシールバー 3 2と ァクチユエータ（図示せず）とを連結してシールバー 3 2を垂直に往復運動させ るロッド 3 5と、 スパゥト口部 2 2上にィンナーシール材 2 3を仮シールする 際の加熱源となるヒーター 3 6と、 仮シール温度を制御するためにシールパー 3 2の温度を測定する温度センサ 3 7と、 必要なィンナーシール材 2 3を打ち 抜く筒状カッター 3 8と、 を主要な構成要素としてなるものである。 First, the inner seal material 23 is temporarily sealed onto the spout portion 22 of the spouted bouch 20 by the temporary seal device 30 for the inner seal material. This temporary sealing device 30 includes a temporary sealing mechanism 31 having a sealing bar 32 having a tip protruding outward and a spouted bouch 20 filled with contents during temporary sealing. And a deaeration plate mechanism 3 4 (see FIGS. 3 and 4) for pressing the bouch portion 20 a located above the contents surface 27. The most suitable method for sealing is by heating the seal. For example, it can be applied with a weak adhesive paste or by applying pressure to the seal. The temporary seal mechanism 3 1 includes the above-described seal bar 3 2, a rod 3 5 that connects the seal bar 3 2 and an actuator (not shown) to reciprocate the seal bar 3 2 vertically, and a spout. Heater 3 6 serving as a heating source for temporarily sealing the inner seal material 2 3 on the mouth 2 2 and a seal part for controlling the temporary seal temperature The main components are a temperature sensor 37 that measures the temperature of 32, and a cylindrical cutter 38 that punches out the necessary inner seal material 23.
前記シールパー 3 2は、 その先端部近くまでヒーター 3 6が揷入され、 さら に、 先端部のヒーター 3 6近傍の孔に温度センサ 3 7も埋込設置されている。 シールバー先端面の外方に凸形状とは、 例えば、 第 5図に示す先端面の縁部の みを面取りした状態、第 6図に示す先端面の縁部を R状にした状態、あるいは、 第 7図に示す先端面全体を球面状に形成した状態が例示される。 また、 このシ 一ルバ一 3 2は、 その先端の凸形状 3 3部分がヒーター 3 6により加熱され、 温度センサ 3 7により逐一シール凸形状 3 3の温度が計測されて、 スパゥトロ 部 2 2上にインナーシール材 2 3を仮シールする際の温度管理がなされている。 なお、 インナーシール材 2 3の材質としては、 ァノレミ箔、 アルミ積層体、 また は蒸着フィルム等のパリア性シート等が採択される。 また。 第 2図中、 3 9は 温度センサ 3 7のリード線 3 7 aを止めるためのパンドである。  The seal par 32 has a heater 36 inserted in the vicinity of the tip thereof, and a temperature sensor 37 is also embedded in a hole near the heater 36 at the tip. The convex shape outward of the seal bar tip surface means, for example, a state where only the edge of the tip surface shown in FIG. 5 is chamfered, a state where the edge of the tip surface shown in FIG. A state in which the entire front end surface shown in FIG. 7 is formed into a spherical shape is illustrated. In addition, the convex part 3 3 of the tip of the seal bar 3 2 is heated by the heater 3 6, and the temperature of the convex part 3 3 of the seal is measured one by one by the temperature sensor 3 7, and the top part 2 2 In addition, the temperature is controlled when the inner seal material 23 is temporarily sealed. As the material of the inner seal material 23, an aluminum foil, an aluminum laminate, or a pariatic sheet such as a vapor deposition film is adopted. Also. In FIG. 2, 3 9 is a panda for stopping the lead wire 3 7 a of the temperature sensor 3 7.
したがって、 供給工程 1にて、 保持部材 2 1にスパゥト付パゥチ 2 0を吊り 下げ保持する際、 多少のズレが生じて、 スパゥトロ部 2 2上端部が水平になる ように吊り下げ保持されていなくても、 シールバー 3 2先端面のシール凸形状 3 3はスパゥトロ部 2 2の開口端部における内端全周 2 2 aに当接して、 全周 シールを実現することが可能となる。  Therefore, in the supply process 1, when the pouch with spout 20 is suspended and held on the holding member 21, there is a slight deviation, and the spout portion 2 2 is not suspended and held so that the upper end is horizontal. However, the seal convex shape 33 on the front end surface of the seal bar 3 2 abuts on the entire inner periphery 2 2 a at the opening end of the supertro section 22 2, so that it is possible to realize the all-round seal.
前記ロッド 3 5は、 一端がァクチユエータ （図示せず） に連結し、 他端がシ 一ルバ一 3 2に連結して、 さらに、 ロッ ド 3 5内を前記ヒーター 3 6が貫通し ている。 また、 前記筒状カッター 3 8はァクチユエータ （図示せず） に連結さ れており、 ロッド 3 5の外側を同心状に摺動し、 仮シールに必要なィンナーシ 一ル材をインナーシール材 2 3から打ち抜くことが可能になる。  One end of the rod 35 is connected to an actuator (not shown), the other end is connected to a seal bar 32, and the heater 36 passes through the rod 35. The cylindrical cutter 38 is connected to an actuator (not shown). The cylindrical cutter 38 slides concentrically on the outside of the rod 35, and the inner seal material 2 3 is used as a temporary seal material for temporary sealing. It becomes possible to punch from.
前記脱気板機構 3 4は、 スパゥト付バウチ 2 0内の内容物面 2 7より上に位 置するバウチ部位 2 0 aを押圧する上部脱気板 4 0と、 押圧動作を実現するァ クチユエータ 4 1と、 該ァクチユエータ 4 1と上部脱気板 4 0とを連結する連 結バー 4 2とで構成し、 制御部から送られてくるタイムスケジュールに基づい て、 ァクチユエータ 4 1が往復運動を行い、 連結パー 4 2を経て上部脱気板 4 0にて上記内容物面 2 7いり上に位置するバウチ部位 2 0 aの押圧 ·解除を 繰り返す。 内容物面 2 7より上に位置するパゥチ部位 2 0 aを押圧する理由は、 脱気工程時の内容物面の昇降がないため、 バウチの変形を防止でき、 縮小変形 状態を保持することが出来、 さらに、 スパゥト付バウチ 2 0内の含気量を調整 出来、 且つ空気の吸込現象を規制することも出来るからである。 なお、 第 3図 はスパゥト付のガセットバウチを上部脱気板 4 0にて押圧する場合を示し、 第 4図はスタンディングバウチを上部脱気板 4 0にて押圧する場合を示している。 次に図面を参照して、 上記構成になるインナーシール材の仮シール装置 3 0 により、 仮シール方法について説明する。 The deaeration plate mechanism 34 includes an upper deaeration plate 40 that presses the bouch part 20 a positioned above the contents surface 27 in the spouted bouch 20, and a pressing operation. The actuator 4 1 is composed of a coupling bar 4 2 that connects the actuator 4 1 and the upper deaeration plate 40, and the actuator 4 1 reciprocates based on the time schedule sent from the control unit. And repeatedly press and release the bout portion 20 a located above the contents surface 27 by the upper deaeration plate 40 through the connecting par 42. The reason for pressing the pouch part 2 0a located above the contents surface 2 7 is that the contents surface does not move up and down during the deaeration process, so that the deformation of the bouch can be prevented and the reduced deformation state can be maintained. This is because the air content in the spouted bouch 20 can be adjusted, and the air suction phenomenon can be regulated. 3 shows the case where the spouted gusset bouch is pressed by the upper deaeration plate 40, and FIG. 4 shows the case where the standing bouch is pressed by the upper deaeration plate 40. Next, a temporary sealing method will be described with reference to the drawings, using the inner seal material temporary sealing device 30 having the above-described configuration.
まず、 脱気 ·充填工程 4にて内容物を充填されたスパゥト付バウチ 2 0は、 口部洗浄 ·窒素置換工程 6を順次経て、 脱気 ·仮シール ·打ち抜き工程 7に送 られる。 この工程 7でィンナーシール材の仮シール装置 3 0における脱気板機 構 3 4の上部脱気板 4 0にて、 スパゥト付バウチ 2 0内の含気量を適生に調整 する。  First, the spouted bouch 20 filled with the contents in the degassing / filling process 4 is sequentially sent to the degassing / temporary seal / punching process 7 through the mouth cleaning / nitrogen replacement process 6.
