Abstract

A method of manufacturing tetrahedral-shaped extract bags (6) made from a sheet (5) adapted to manufacture the extract bags and formed as a tubular body to be filled with contents. In the method, the sheet (5) is alternately fusion bonded and fusion cut in directions crossing each other in a plan view to form first side seals and second side seals, and, while the first side seals and the second side seals are alternately formed, the insides of tubular bodies made from the sheet (5) are filled with contents. Rockable plates (91a, 91b, 91c, 91d) rockably installed inside the tubular body of the sheet (5) are rocked before each side seal is formed, and this forms each side seal with the seal portions alternately extended flat in their respective seal directions. Electromagnets (92a, 92b, 92c, 92d) or, alternatively, gas injections (nozzles (94a, 94b, 94c, 94d)) are used as drive sources for rocking the rockable plates (91a, 91b, 91c, 91d). The extract bags of a tetrahedral shape are manufactured without causing wrinkles in the seal portions.

Description

抽出バッグの製造方法Extraction bag manufacturing method

　本発明は、帯状の抽出バッグ用シートから四面体形状の抽出バッグを製造する方法及びその方法を実施する抽出バッグ用充填包装機に関する。 The present invention relates to a method for producing a tetrahedral-shaped extraction bag from a belt-shaped extraction bag sheet and a filling and packaging machine for the extraction bag for carrying out the method.

　紅茶、緑茶、ハーブ等のティーバッグ、煮干し、鰹節等のだしの抽出バッグとして、不織布等の通水濾過性の抽出バッグ用シートを四面体形状の袋体に形成すると共に、その内部に茶葉等の抽出材料を充填し、外表面にタグ付き吊し糸を取り付けたものが使用されている。 As a tea bag for black tea, green tea, herbs, etc., as a bag for extracting dried stock such as dried and dried bonito, a water filterable extraction bag sheet such as non-woven fabric is formed into a tetrahedron-shaped bag body, and tea leaves are formed inside it. And the like, which are filled with an extraction material and the like and attached with a hanging thread with a tag on the outer surface are used.

　このような抽出バッグの製造としては、抽出バッグ用シートとして、帯状の通水濾過性シートに、吊し糸となる糸材とタグとを配置したもの（特許文献１、特許文献２）を製造し、その対向縁部を互いに接着することにより筒状に成形した後、その筒状体を押し潰して幅方向に溶着溶断する第１の横シールの形成と、それと交差する幅方向に溶着溶断する第２の横シールの形成とを交互に行うと共に、これらの横シールの形成の間に内容物を充填する方法が行われている（特許文献１、特許文献２）。 As a manufacture of such an extraction bag, as a sheet for an extraction bag, a belt-shaped water-permeable filterable sheet in which a thread material and a tag serving as a hanging thread are arranged (Patent Document 1, Patent Document 2) is manufactured. And forming the first horizontal seal that crushes the cylindrical body and welds and cuts it in the width direction, and welds and cuts in the width direction that intersects it. A method of alternately performing the formation of the second horizontal seal and filling the contents during the formation of these horizontal seals is performed (Patent Document 1, Patent Document 2).

　しかしながら、このような抽出バッグの製造方法では、横シール時に抽出バッグ用シートにシワが発生し易い。そこで、横シール時にシワが発生することを防止するため、抽出バッグ用シートを筒状に成形した後、その抽出バッグ用シートの筒状体の内側に位置する十字状の噴射ノズルから、横シール直前に抽出バッグ用シートにガスを噴射することによりその筒状体を扁平にし、扁平にした状態で横シールをすることが提案されている（特許文献３）。 However, in such a method for manufacturing an extraction bag, wrinkles are likely to occur on the sheet for the extraction bag during horizontal sealing. Therefore, in order to prevent wrinkles from occurring during the horizontal sealing, after forming the extraction bag sheet into a cylindrical shape, the horizontal sealing is performed from the cross-shaped injection nozzle located inside the cylindrical body of the extraction bag sheet. It has been proposed that the cylindrical body is flattened by injecting gas onto the extraction bag sheet immediately before, and then laterally sealed in a flattened state (Patent Document 3).

　また、筒状体に成形した抽出バッグ用シートの外側に位置するガス噴射ノズルから、横シール直前にその筒状体にガスを噴射することにより筒状体を扁平にし、扁平にした状態で横シールすることが提案されている（特許文献４）。 In addition, the cylindrical body is flattened by injecting gas from the gas injection nozzle located outside the extraction bag sheet formed into a cylindrical body into the cylindrical body immediately before the horizontal seal, and in the flattened state, Sealing has been proposed (Patent Document 4).

　この他、筒状体に成形した抽出バッグ用シートの内部に内容物を送り込む供給筒に、特定形状の帯板状のバネを摺動自在に取り付け、その帯板状のバネを供給筒から押し下げることにより、筒状体に成形した抽出バッグ用シートを扁平化する方法も知られている（特許文献５）。

Thus, a method of flattening the extraction bag sheet formed into a cylindrical body is also known (Patent Document 5).

　しかしながら、噴射したガスは抽出バッグ用シートを容易に通り抜けるため、特許文献３に記載の従来の抽出バッグの製造方法では、通水濾過性シートの筒状体を十分に扁平にすることができない。また、噴射ノズルからガスを強く噴射させると、抽出バッグの内容物とする茶葉等が舞い上がるという不都合が発生する。 However, since the injected gas easily passes through the extraction bag sheet, the conventional extraction bag manufacturing method described in Patent Document 3 cannot sufficiently flatten the tubular body of the water-permeable filter sheet. In addition, when gas is strongly jetted from the jet nozzle, there is a disadvantage that tea leaves or the like as the contents of the extraction bag rise.

　また、特許文献４に記載の方法では、ガスの噴射による茶葉等の舞い上がりは低減するものの、シワの発生を解消することはできない。 In the method described in Patent Document 4, the rise of tea leaves and the like due to gas injection is reduced, but the generation of wrinkles cannot be eliminated.

　特許文献５に記載の方法では、帯板状のバネが、常に供給筒に押しつけられている状態で摺動するので、帯板状のバネが摩滅し易く、耐久性に欠ける。 In the method described in Patent Document 5, since the strip-shaped spring slides while being always pressed against the supply cylinder, the strip-shaped spring is easily worn out and lacks durability.

　これに対し、本発明は、シール部分にシワのない四面体形状の抽出バッグを安定して製造できるようにすることを目的とする。 On the other hand, an object of the present invention is to make it possible to stably manufacture a tetrahedral-shaped extraction bag having no wrinkles in a seal portion.

　本発明者は、四面体形状の抽出バッグを製造するにあたり、筒状体に成形した抽出バッグ用シートの内側に揺動プレートが位置するようにし、その揺動プレートを揺動させて機械的に抽出バッグ用シートの筒状体を扁平にすると、それに続く横シールでのシワの発生を確実に防止できることを見いだした。 In manufacturing the tetrahedral extraction bag, the inventor mechanically moves the swing plate so that the swing plate is positioned inside the extraction bag sheet formed into a cylindrical body. It has been found that if the cylindrical body of the extraction bag sheet is flattened, wrinkles can be reliably prevented from occurring in the subsequent horizontal seal.

　即ち、本発明は、筒状体に成形された抽出バッグ用シートを、上面視で互いに交差する方向に交互に溶着溶断することにより第１の横シールと第２の横シールを交互に形成すると共に、
第１の横シールの形成と第２の横シールの形成を交互に繰り返す間に、抽出バッグ用シートの筒状体の内部に内容物を充填する四面体形状の抽出バッグの製造方法であって、

With

　本発明によれば、筒状体に成形した抽出バッグ用シートを、揺動プレートで確実に扁平にした後に横シールを行うので、横シールにシワのない綺麗な四面体形状の抽出バッグを製造することができる。 According to the present invention, since the sheet for the extraction bag formed into a cylindrical body is securely flattened with the swing plate and then laterally sealed, the laterally sealed wrinkle-free extraction bag having a beautiful tetrahedral shape is manufactured. can do.

　この場合、抽出バッグの扁平化は、筒状体に成形した抽出バッグ用シートの内側で揺動プレートを揺動させることにより行うため、抽出バッグ用シートを筒状体に成形した後、第１の横シールとそれに交差する方向の第２の横シールを交互に行うことにより抽出バッグを製造するという公知の抽出バッグ用充填包装機で広く適用することができる。 In this case, the flattening of the extraction bag is performed by swinging the swinging plate inside the extraction bag sheet formed into a cylindrical body. Therefore, after the extraction bag sheet is formed into a cylindrical body, the first The present invention can be widely applied to known extraction bag filling and packaging machines in which an extraction bag is manufactured by alternately performing a horizontal seal and a second horizontal seal in a direction crossing the horizontal seal.

　また、揺動プレートの揺動は、第１の横シールと第２の横シールのシール速度を高めた場合でも各横シールに容易に同期させることができるので、抽出バッグの生産速度を向上させることができ、さらにこのような揺動により揺動プレートの耐久性が損なわれることもない。 Further, since the swing of the swing plate can be easily synchronized with each horizontal seal even when the sealing speed of the first and second horizontal seals is increased, the production speed of the extraction bag is improved. Further, the durability of the swing plate is not impaired by such swinging.

　また、揺動プレートの揺動により、筒状体に成形した抽出バッグ用シート内で内容物が舞い上がることもない。 Also, the contents do not soar in the extraction bag sheet formed into a cylindrical body by the swinging of the swinging plate.

　以下、図面を参照しつつ、本発明を具体的に説明する。なお、各図中、同一符号は同一又は同等の構成要素を表している。 Hereinafter, the present invention will be specifically described with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

　図１は、本発明の抽出バッグの製造方法を実施する一実施例の抽出バッグ用充填包装機７０の模式図であり、図２は、その充填包装機７０において横シールを行う横シール装置７６付近の側面図である。また、図３は、筒状に形成した抽出バッグ用シートを、横シールに先立って扁平にする扁平手段９０の模式図であり、図４Ａ、図４Ｂは、扁平手段の断面図である。 FIG. 1 is a schematic view of an extraction bag filling and packaging machine 70 according to an embodiment for carrying out the extraction bag manufacturing method of the present invention, and FIG. 2 is a horizontal sealing device 76 that performs horizontal sealing in the filling and packaging machine 70. FIG. FIG. 3 is a schematic view of the flat means 90 for flattening the extraction bag sheet formed in a cylindrical shape prior to the horizontal seal, and FIGS. 4A and 4B are cross-sectional views of the flat means.

　この充填包装機７０は、抽出バッグ用シート５を用いて四面体形状の抽出バッグ６を製造する機械であって、概略、抽出バッグ用シート５を案内するフォーマーガイド７２を備えた筒体７３、筒体７３に巻き付けた抽出バッグ用シート５を一定速度で下方に走行させるシート送り手段（送りローラ７４）、抽出バッグ用シート５の長手方向の両側縁部を溶着することにより筒状体に形成する縦シール装置７５、筒状体に形成した抽出バッグ用シートを、上面視で互いに交差する方向に溶着溶断することにより第１の横シールと第２の横シールを交互に形成する横シール装置７６、第１の横シールの形成と第２の横シールの形成を交互に繰り返す間に、抽出バッグの内容物となる茶葉等を筒体７３に所定量ずつ送り込み、抽出バッグ用シート５の筒状体の内部に茶葉等を充填するオーガ充填装置８０を有している。また、縦シール装置７５と横シール装置７６の間には、本発明に特徴的な扁平手段９０を有している。この扁平手段９０は、後述するように、筒状に形成した抽出バッグ用シート５を、横シールに先立って扁平にし、横シール時にシワが発生することを防止する。 This filling and packaging machine 70 is a machine for producing a tetrahedral-shaped extraction bag 6 using the extraction bag sheet 5, and is roughly a cylinder 73 having a former guide 72 for guiding the extraction bag sheet 5. A sheet feeding means (feeding roller 74) for causing the extraction bag sheet 5 wound around the cylinder 73 to travel downward at a constant speed, and by welding both side edges in the longitudinal direction of the extraction bag sheet 5 to the cylindrical body The vertical seal device 75 to be formed, and the horizontal seal that alternately forms the first horizontal seal and the second horizontal seal by welding and cutting the sheet for the extraction bag formed in the cylindrical body in a direction crossing each other in a top view. While repeating the formation of the apparatus 76 and the formation of the first horizontal seal and the formation of the second horizontal seal alternately, the tea leaves or the like as the contents of the extraction bag are fed into the cylinder 73 by a predetermined amount, and the sheet for the extraction bag And a auger filling device 80 for filling the tea leaves or the like in the interior of the tubular body. Further, a flat means 90 characteristic of the present invention is provided between the vertical sealing device 75 and the horizontal sealing device 76. As will be described later, the flat means 90 flattens the extraction bag sheet 5 formed in a cylindrical shape prior to the horizontal seal, and prevents wrinkles from occurring during the horizontal seal.

　縦シール装置７５としては、超音波溶着溶断装置を備えており、縦シール形成時に生じる不要な縁部（耳部）を巻き取るスクラップ巻き取り手段７７を備えている。 As the vertical seal device 75, an ultrasonic welding fusing device is provided, and a scrap winding means 77 is provided for winding up an unnecessary edge (ear portion) generated when the vertical seal is formed.

　横シール装置７６としては、各横シールの形成毎に、抽出バッグ用シート５の筒状体の軸Ｌを中心に溶着溶断方向が所定角度、好ましくは９０°、揺動し、図１において実線で記載した位置と破線で記載した位置を交互にとる一つの超音波溶着溶断装置760を備えている。この超音波溶着溶断装置760は、先端が先細に突出したシールヘッド７６ａと、筒状体に形成されている抽出バッグ用シートを横シールの形成時に平坦に押し潰す押さえ７８とを有する。 As the horizontal sealing device 76, the welding fusing direction is swung by a predetermined angle, preferably 90 °, around the axis L of the cylindrical body of the extraction bag sheet 5 every time the horizontal seal is formed. And an ultrasonic welding fusing device 760 that alternately takes the position described by the broken line and the position described by the broken line. This ultrasonic welding fusing device 760 has a seal head 76a having a tapered tip and a presser 78 that flatly crushes an extraction bag sheet formed on a cylindrical body when a horizontal seal is formed.

　シールヘッド７６ａは、先端が先細に突出しており、それを走行させることにより任意の長さにシールを形成することができる所謂走行式のものである。走行式のシールヘッドを用いることにより、シールヘッドを小型軽量化することができるので、高速で駆動させることが容易となり、また、その駆動機構をコンパクトに構成することが可能となる。 The seal head 76a is a so-called traveling type in which the tip protrudes in a tapered manner and a seal can be formed to an arbitrary length by traveling the seal head 76a. By using a traveling type seal head, the seal head can be reduced in size and weight, so that it can be easily driven at a high speed and the drive mechanism can be made compact.

　押さえ７８は、横シールの形成幅を有しており、横シール形成時に、抽出バッグ用シートと共に下方に走行する。シールヘッド７６ａは、押さえ７８が抽出バッグ用シート５の筒状体を平坦に押し潰している状態で、その抽出バッグ用シート５に当接し、その押し潰されている筒状体の幅方向に走行すると共に、下方にも走行し、これにより、抽出バッグ用シート５の下方への走行を停止させることなく、一定の走行速度を維持しつつ横シールを形成する。そして該横シールの形成後、シールヘッド７６ａは、その横シールを形成する間の抽出バッグ用シート５の下方への走行距離をキャンセルする位置に戻し走行する。 The presser 78 has a width for forming a horizontal seal, and travels downward together with the extraction bag sheet when the horizontal seal is formed. The seal head 76a is in contact with the extraction bag sheet 5 in a state where the presser 78 flatly crushes the cylindrical body of the extraction bag sheet 5, and in the width direction of the crushed cylindrical body. While traveling, it also travels downward, thereby forming a horizontal seal while maintaining a constant traveling speed without stopping traveling downward of the extraction bag seat 5. After the formation of the horizontal seal, the seal head 76a travels back to a position where the downward travel distance of the extraction bag seat 5 during the formation of the horizontal seal is canceled.

　したがって、シールヘッド７６ａのトータルの動きとしては、第１の横シールの形成時には、上述の幅方向と下方の動きの合成により、矢印ａのように斜め下方に走行する。そして、該横シールを形成後、該横シールを形成する間の抽出バッグ用シート５の下方への走行距離をキャンセルすると共に軸Ｌを中心に９０°揺動した位置に矢印ｂのように戻し走行する。その後、第１の横シールと同様に、シールヘッドを矢印ｃのように斜め下方に走行することにより第２の横シールを形成し、その後、矢印ｄのように戻し走行する。この場合、シールヘッド７６ａに対向するアンビル７６ｂも、第１の横シールの形成時には抽出バッグ用シート５と共に矢印ａ’のように下方に走行し、その後、第１の横シールを形成するの間の下方への走行距離をキャンセルすると共に軸Ｌを中心に９０°揺動した位置に矢印ｂ’のように戻し走行し、第２の横シールを形成する間は矢印ｃ’のように下方に走行し、その後矢印ｄ’のように戻し走行する。以降、この第１の横シールの形成と第２の横シールの形成を繰り返す。 Therefore, as a total movement of the seal head 76a, when the first horizontal seal is formed, the seal head 76a travels obliquely downward as indicated by an arrow a by combining the above-described width direction and downward movement. Then, after the horizontal seal is formed, the downward travel distance of the extraction bag seat 5 during the formation of the horizontal seal is canceled and returned to the position swung by 90 ° about the axis L as shown by the arrow b. Run. Thereafter, similarly to the first horizontal seal, the seal head travels obliquely downward as indicated by an arrow c to form a second horizontal seal, and then travels back as indicated by an arrow d. In this case, the anvil 76b facing the seal head 76a also travels downward as indicated by the arrow a ′ together with the extraction bag sheet 5 when the first horizontal seal is formed, and then forms the first horizontal seal. The travel distance below is canceled and the vehicle travels back as indicated by the arrow b 'to the position swung by 90 ° about the axis L. While forming the second horizontal seal, it moves downward as indicated by the arrow c'. Travel and then travel back as indicated by arrow d '. Thereafter, the formation of the first horizontal seal and the formation of the second horizontal seal are repeated.

　扁平手段９０は、縦シール装置７５で抽出バッグ用シート５を筒状体に形成した後、横シール装置７６で第１、第２の各横シールを形成するのに先立ち、抽出バッグ用シート５の筒状体を各横シールの方向に伸ばして扁平にするものであり、図３に示すように、４個の揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄからなっている。より具体的には、図３、図４Ａに示すように、４個の揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄは、筒状体に成形された抽出バッグ用シート５の内部に内容物を送り込む筒体７３の下端部において該筒体７３の外側表面のみの切欠部分に、軸Ｌを中心に９０°間隔でピン９３によって揺動可能に取り付けられており、このうち２個の揺動プレート９１ａ、９１ｂは第１の横シール方向に配列し、残り２個の揺動プレート９１ｃ、９１ｄは第２の横シール方向に配列している。 The flat means 90 forms the extraction bag sheet 5 into a cylindrical body by the vertical sealing device 75 and then forms the first and second horizontal seals by the horizontal sealing device 76 before the extraction bag sheet 5. This cylindrical body is flattened by extending in the direction of each horizontal seal, and as shown in FIG. 3, it is composed of four swing plates 91a, 91b, 91c, 91d. More specifically, as shown in FIGS. 3 and 4A, the four swing plates 91a, 91b, 91c, 91d feed the contents into the extraction bag sheet 5 formed into a cylindrical body. At the lower end portion of the cylindrical body 73, it is attached to a notch portion only on the outer surface of the cylindrical body 73 so as to be swingable by pins 93 at an interval of 90 ° about the axis L, of which two swing plates 91a 91b are arranged in the first horizontal sealing direction, and the remaining two swing plates 91c, 91d are arranged in the second horizontal sealing direction.

　各揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄは、く字型に屈曲した板状部材からなり、これにより、各揺動プレートは、それに格別外力が加えられない状態では、その下端部９１ｐが軸Ｌの近傍寄りに位置し、軽微な外力で容易に動く。このため、第１の揺動プレート９１ａ、９１ｂが矢印のように揺動して抽出バッグ用シートの筒状体を扁平に伸ばすときには、第２の揺動プレート９１ｃ、９１ｄがその扁平化の妨げになることはなく、同様に第２の９１ｃ、９１ｄが揺動して抽出バッグ用シートの筒状体を扁平に伸ばすときには、第１の揺動プレート９１ａ、９１ｂがその扁平化の妨げになることはない。 Each oscillating plate 91a, 91b, 91c, 91d consists of a plate-like member bent in a square shape, so that each oscillating plate has its lower end 91p pivoted when no special external force is applied thereto. It is located near L and moves easily with a slight external force. For this reason, when the first swing plates 91a and 91b swing as shown by the arrows and the cylindrical body of the extraction bag sheet is flattened, the second swing plates 91c and 91d prevent the flattening. Similarly, when the second 91c, 91d swings and the cylindrical body of the extraction bag sheet is flattened, the first swing plates 91a, 91b hinder the flattening. There is nothing.

　また、各揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄは、揺動により過度にその下端部９１ｐが、筒状体に成形されている抽出バッグ用シートの外側に突出すると、抽出バッグ用シート５が下方に走行しなくなる。そのため、このような揺動プレートの下端部９１ｐの過度の突出を防止するため、揺動により、各揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄの上端部９１ｑが筒体７３の下端部の切欠残存部分に突き当たり、それ以上の揺動が起きないようにしている。なお、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄの過度の揺動を押さえる方法としては、後述するように、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄを筒体７３の下端部に該筒体７３の全厚を切り欠くことにより取り付け、揺動プレートの上端部９１ｑがオーガ充填装置８０のファネルの管状の足８１に突き当たるようにしてもよい（図９）。 Further, when the swing plate 91a, 91b, 91c, 91d excessively protrudes the lower end portion 91p of the swing bag 91 to the outside of the extraction bag sheet formed into a cylindrical body, the extraction bag sheet 5 is It will not run downward. Therefore, in order to prevent such an excessive protrusion of the lower end portion 91p of the swing plate, the upper end portion 91q of each swing plate 91a, 91b, 91c, 91d is notched at the lower end portion of the cylindrical body 73 by swinging. It strikes the part and prevents further swinging. In addition, as a method of suppressing excessive rocking of the rocking plates 91a, 91b, 91c, and 91d, the rocking plates 91a, 91b, 91c, and 91d are attached to the lower end portion of the cylinder 73 as described later. The upper end portion 91q of the swing plate may abut against the funnel tubular leg 81 of the auger filling device 80 (FIG. 9).

　扁平手段９０は、上述の揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄを揺動させる駆動源として、抽出バッグ用シートの筒状体の外側に合計４個の電磁石９２ａ、９２ｂ、９２ｃ、９２ｄを有している。このうち２個の電磁石９２ａ、９２ｂは、第１の横シール方向に配列し、揺動プレート９１ａ、９１ｂと対向している。また、他の２個の電磁石９２ｃ、９２ｄは、第２の横シール方向に配列し、揺動プレート９１ｃ、９１ｄと対向している。 The flat means 90 has a total of four electromagnets 92a, 92b, 92c, 92d on the outside of the cylindrical body of the extraction bag sheet as a drive source for swinging the swing plates 91a, 91b, 91c, 91d. is doing. Of these, the two electromagnets 92a and 92b are arranged in the first horizontal sealing direction and face the swing plates 91a and 91b. The other two electromagnets 92c and 92d are arranged in the second lateral seal direction and face the swing plates 91c and 91d.

　揺動プレート９１ａ、９１ｂを揺動させて第１の横シール用の扁平状態を形成する場合には、第１の横シール方向に配列した電磁石９２ａ、９２ｂをＯＮとし、第２の横シール方向に配列した電磁石９２ｃ、９２ｄをＯＦＦとする。これにより、図４Ｂに示すように、第１の横シール方向に配列した電磁石９２ａ、９２ｂで揺動プレート９１ａ、９１ｂを引きつけ、その下端部９１ｐを矢印ｋのように、抽出バッグ用シート５の筒状体の外側方向に移動させ、抽出バッグ用シート５の筒状体を扁平にする。 When the swing plates 91a and 91b are swung to form a flat state for the first side seal, the electromagnets 92a and 92b arranged in the first side seal direction are turned on, and the second side seal direction The electromagnets 92c and 92d arranged in the are turned off. Accordingly, as shown in FIG. 4B, the swinging plates 91a and 91b are attracted by the electromagnets 92a and 92b arranged in the first lateral sealing direction, and the lower end portion 91p of the extraction bag sheet 5 is indicated by the arrow k. It moves to the outer side of a cylindrical body, and the cylindrical body of the sheet | seat 5 for extraction bags is made flat.

　なお、電磁石９２ａ、９２ｂの配設位置としては、図４Ｂに示したように揺動プレート９１ａ、９１ｂが最も大きく揺動したときでも、この揺動プレート９１ａ、９１ｂ上の抽出バッグ用シート５と接しない限りで、非揺動時の揺動プレート９１ａ、９１ｂに近接した位置とすることが好ましい。揺動プレート９１ａ、９１ｂが抽出バッグ用シート５の筒状体を、その筒状体の外側方向に伸ばしている時に、電磁石９２ａ、９２ｂが抽出バッグ用シートに接触すると、抽出バッグ用シート５の下方への走行に支障がきたされるからである。 The electromagnets 92a and 92b are disposed at the positions of the extraction bag sheet 5 on the swing plates 91a and 91b even when the swing plates 91a and 91b swing the largest as shown in FIG. 4B. As long as they are not in contact with each other, the position is preferably close to the swing plates 91a and 91b when not swinging. When the swinging plates 91a and 91b extend the cylindrical body of the extraction bag sheet 5 in the outward direction of the cylindrical body, the electromagnets 92a and 92b come into contact with the extraction bag sheet, and This is because it hinders traveling downward.

　こうして第１の横シール方向に抽出バッグ用シート５の筒状体を扁平化した後、上述の横シール装置７６で第１の横シールを形成する。 Thus, after flattening the cylindrical body of the extraction bag sheet 5 in the first lateral seal direction, the first lateral seal is formed by the lateral seal device 76 described above.

　これに引き続き、第２の横シール方向に配列した揺動プレート９１ｃ、９１ｄを揺動させて第２の横シール用の扁平状態を形成する場合には、第１の横シール方向に配列した電磁石９２ａ、９２ｂはＯＦＦとし、第２の横シール方向に配列した電磁石９２ｃ、９２ｄをＯＮとし、この電磁石９２ｃ、９２ｄで第２の横シール方向に配列した揺動プレート９１ｃ、９１ｄを引きつけ、その下端部９１ｐを抽出バッグ用シート５の筒状体の外側方向に移動させ、この筒状体５を扁平にする。こうして第２の横シール方向に抽出バッグ用シート５の筒状体を扁平化した後は、上述の横シール装置７６で第２の横シールを形成する。 Subsequently to this, when the flat state for the second horizontal seal is formed by swinging the swing plates 91c, 91d arranged in the second horizontal seal direction, the electromagnets arranged in the first horizontal seal direction. 92a and 92b are turned off, the electromagnets 92c and 92d arranged in the second transverse seal direction are turned on, and the swing plates 91c and 91d arranged in the second transverse seal direction are attracted by the electromagnets 92c and 92d, and the lower ends thereof The portion 91p is moved in the outer direction of the cylindrical body of the extraction bag sheet 5, and the cylindrical body 5 is flattened. After flattening the cylindrical body of the extraction bag sheet 5 in the second lateral sealing direction in this way, the second lateral seal is formed by the lateral sealing device 76 described above.

　扁平手段９０は、このように第１の横シール方向に配列した電磁石９２ａ、９２ｂのＯＮと第２の横シール方向に配列した電磁石９２ｃ、９２ｄのＯＦＦ、及び第１の横シール方向に配列した電磁石９２ａ、９２ｂのＯＦＦと第２の横シール方向に配列した電磁石９２ｃ、９２ｄのＯＮを交互に繰り返すことにより、横シール手段７６が第１の横シールを行う直前には抽出バッグ用シートの筒状体を第１の横シール方向に伸ばして扁平にし、第２の横シールを行う直前には、抽出バッグ用シートの筒状体を第２の横シール方向に伸ばして扁平にする。したがって、この充填包装機７０によれば、抽出バッグ用シート５の筒状体を揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄで確実に扁平にした状態で第１、第２のそれぞれの横シールを形成するので、横シール形成時のシワの発生を解消することができ、きれいな四面体状の抽出バッグ６を得ることができる。 The flat means 90 is arranged in the first transverse seal direction, the electromagnets 92a and 92b arranged in the first transverse seal direction are turned on, the electromagnets 92c and 92d arranged in the second transverse seal direction are turned off, and the first transverse seal direction. By alternately turning off the electromagnets 92a and 92b and turning on the electromagnets 92c and 92d arranged in the second lateral seal direction, the cylinder of the extraction bag sheet immediately before the lateral seal means 76 performs the first lateral seal. The cylindrical body of the extraction bag sheet is extended and flattened in the second horizontal sealing direction immediately before the second horizontal sealing is performed. Therefore, according to this filling and packaging machine 70, the first and second horizontal seals are provided in a state where the cylindrical body of the extraction bag sheet 5 is securely flattened by the swing plates 91a, 91b, 91c, 91d. Since it forms, the generation | occurrence | production of the wrinkle at the time of horizontal seal formation can be eliminated, and the beautiful tetrahedral extraction bag 6 can be obtained.

　この場合、電磁石９２ａ、９２ｂ、９２ｃ、９２ｄのＯＮ、ＯＦＦは、容易に第１の横シールの形成や第２の横シールの形成に同期させることができるので、抽出バッグ用シートの筒状体の扁平化により抽出バッグの生産速度が低下することはなく。また、この扁平化に伴い、抽出バッグ用シートの筒状体内に充填する内容物が舞い上がることもない。 In this case, since the ON / OFF of the electromagnets 92a, 92b, 92c, and 92d can be easily synchronized with the formation of the first horizontal seal and the second horizontal seal, the cylindrical body of the extraction bag sheet The flattening of the extraction bag does not reduce the production speed of the extraction bag. Further, with this flattening, the contents filled in the cylindrical body of the extraction bag sheet do not rise.

　この充填包装機７０において、上述の扁平手段９０及び横シール装置７６の動きは、図２に示す駆動機構により行われる。即ち、充填包装機７０は、ベースプレート上下駆動用サーボモータ761と、このサーボモータ761に接続したクランク762とリンク763により上下動を繰り返すベースプレート764を有している。また、９０°揺動用サーボモータ770と、このサーボモータ770とスプライン軸771で接続され、９０°揺動を繰り返す９０°揺動プレート772を有している。この９０°揺動プレート772は、上述のベースプレート764上に設けられているため、上下動も繰り返す。 In the filling and packaging machine 70, the above-described flat means 90 and the lateral seal device 76 are moved by the drive mechanism shown in FIG. That is, the filling and packaging machine 70 includes a base plate vertical drive servo motor 761 and a base plate 764 that repeats vertical movement by a crank 762 and a link 763 connected to the servo motor 761. Further, the servo motor 770 for 90 ° swing and a 90 ° swing plate 772 that is connected to the servo motor 770 by a spline shaft 771 and repeats 90 ° swing are provided. Since the 90 ° swing plate 772 is provided on the base plate 764 described above, the vertical movement is repeated.

　９０°揺動プレート772上には、シールヘッド７６ａの上述の幅方向の走行と、筒状体に形成されている抽出バッグ用シート５を平坦に押し潰す押さえ７８の横シール位置に対する前後の動きと、アンビル７６ｂの横シール位置に対する前後の動きを担う水平駆動用サーボモータ780を有している。即ち、サーボモータ780の回転は、歯車781によってカム782に伝えられ、カム782の上面に形成された溝を従動するカムフォロア783が、リンク機構784を矢印ｐ（図５）のように揺動させ、それによりアンビル７６ｂが横シール位置に対して水平面内で前後に動く。また、このリンク機構784と接続したロッド785が、押さえ７８の基台786を動かすことにより、押さえ７８を横シール位置に対して水平面内で前後に動かす。 On the 90 ° swing plate 772, the seal head 76a travels in the width direction described above, and the back-and-forth movement of the presser 78 that flatly crushes the extraction bag sheet 5 formed in the cylindrical body with respect to the lateral seal position. And a horizontal drive servo motor 780 that carries forward and backward movement with respect to the lateral seal position of the anvil 76b. That is, the rotation of the servo motor 780 is transmitted to the cam 782 by the gear 781, and the cam follower 783 driven by the groove formed on the upper surface of the cam 782 swings the link mechanism 784 as shown by the arrow p (FIG. 5). This causes the anvil 76b to move back and forth in a horizontal plane relative to the lateral seal position. Further, the rod 785 connected to the link mechanism 784 moves the base 786 of the presser 78, thereby moving the presser 78 back and forth within the horizontal plane with respect to the lateral seal position.

　さらに、カム782の下面にも溝が形成されており、この溝を従動するカムフォロア790がリンク機構791を矢印ｑ（図５）のように揺動させ、これにより、シールヘッド７６ａが幅方向に動く。 Further, a groove is also formed on the lower surface of the cam 782, and a cam follower 790 driven by the groove swings the link mechanism 791 as indicated by an arrow q (FIG. 5), whereby the seal head 76a is moved in the width direction. Move.

　一方、扁平手段９０の電磁石９２ａ、９２ｂ、９２ｃ、９２ｄは、上下動や９０°揺動をしないフレームに、前述の配設位置で固定されている。 On the other hand, the electromagnets 92a, 92b, 92c, and 92d of the flat means 90 are fixed to the frame that does not move up and down or swing by 90 ° at the above-described arrangement position.

　このような駆動機構において、ベースプレート上下駆動用サーボモータ761、９０°揺動サーボモータ770、水平駆動用サーボモータ780は、連動駆動を可能とする制御装置（図示せず）により制御され、制御盤にてそれぞれの回転速度が制御される。また、扁平手段９０の電磁石９２ａ、９２ｂ、９２ｃ、９２ｄのＯＮ、ＯＦＦもこの制御装置で制御される。したがって、横シールの形成直前に電磁石９２ａ、９２ｂ、９２ｃ、９２ｄのＯＮ、ＯＦＦで抽出バッグ用シート５の筒状体を横シール方向に扁平にすることができる。また、横シールの形成時に抽出バッグ用シート５と接する、シールヘッド７６ａ、アンビル７６ｂ及び押さえ７８の走行速度を、抽出バッグ用シート５の走行方向の速度成分について、完全に抽出バッグ用シート５と同速に制御することができる。よって、抽出バッグ用シート５の走行速度に脈動が生じたり、蛇行が生じたりすることを解消でき、綺麗な四面体形状の抽出バッグ６を製造することができる。 In such a drive mechanism, the base plate vertical drive servo motor 761, the 90 ° swing servo motor 770, and the horizontal drive servo motor 780 are controlled by a control device (not shown) capable of interlocking drive. Each rotation speed is controlled by. Moreover, ON / OFF of the electromagnets 92a, 92b, 92c, 92d of the flat means 90 is also controlled by this control device. Therefore, the cylindrical body of the extraction bag sheet 5 can be flattened in the lateral seal direction by turning on and off the electromagnets 92a, 92b, 92c, and 92d immediately before the lateral seal is formed. Further, the traveling speed of the seal head 76a, the anvil 76b, and the presser 78 that are in contact with the extraction bag sheet 5 when the lateral seal is formed is completely the same as that of the extraction bag sheet 5 with respect to the speed component in the traveling direction of the extraction bag sheet 5. It can be controlled at the same speed. Therefore, it is possible to eliminate the occurrence of pulsation or meandering in the running speed of the extraction bag sheet 5, and the extraction bag 6 having a beautiful tetrahedral shape can be manufactured.

　なお、縦シール装置７５及び横シール装置７６を構成する溶着溶断装置としては、超音波によるものの他、加熱によるものを使用してもよい。 In addition, as the welding fusing device constituting the vertical sealing device 75 and the horizontal sealing device 76, a device using heating may be used in addition to a method using ultrasonic waves.

　この抽出バッグ用充填包装機７０にかける抽出バッグ用シート５としては、抽出バッグ製造用の織物、不織布又はこれらの積層体からなる長尺のシートからなり、必要に応じて糸タグを貼着したもの等を種々使用することができる。 The extraction bag sheet 5 to be applied to the extraction bag filling and packaging machine 70 is composed of a long sheet made of a woven fabric, a nonwoven fabric or a laminate thereof for producing an extraction bag, and a thread tag is attached as necessary. Various things can be used.

　例えば、糸材としては、ポリプロピレン、ポリエチレン等の熱可塑性合成繊維をはじめとして超音波溶着や熱溶着が可能な素材から形成されたものを使用することができ、タグとしては、紙、プラスチックシート等から形成されたものを使用することができる。また、通水濾過性シートとしては、ポリエステル、ナイロン、ポリエチレン、ポリプロピレン等の合成繊維、レーヨン等の半合成繊維、コウゾ、ミツマタ等の天然繊維の単独又は複合繊維からなる織布、不織布、紙類、多くの孔を開けたフィルム等を使用することができる。 For example, as a thread material, one formed from a material capable of ultrasonic welding or heat welding including thermoplastic synthetic fibers such as polypropylene and polyethylene can be used, and as a tag, paper, plastic sheet, etc. Can be used. In addition, as the water-permeable filter sheet, synthetic fibers such as polyester, nylon, polyethylene, and polypropylene, semi-synthetic fibers such as rayon, woven fabrics, non-woven fabrics, and papers made of natural fibers such as Kozo and Mitsuma A film having many holes can be used.

　通水濾過性シート上のタグや糸材の配置についても特に制限はない。
　さらに、抽出バッグ用シート５としては、ロール状に巻き回されたものを使用してもよく、抽出バッグ用シートを構成する通水濾過性シートに吊し糸やタグを貼着して抽出バッグ用シートを製造する任意の機械を本発明の抽出バッグ用充填包装機７０と組み合わせて使用してもよい。 There are no particular restrictions on the arrangement of tags and thread materials on the water-permeable filterable sheet.
Furthermore, as the extraction bag sheet 5, a sheet wound in a roll shape may be used, and a hanging thread or tag is attached to a water-permeable filterable sheet constituting the extraction bag sheet. Any machine that produces sheet for use may be used in combination with the extraction bag filling and packaging machine 70 of the present invention.

　本発明の抽出バッグ用充填包装機は、上述した実施例の他、種々の態様をとることができる。例えば、図６に示す抽出バッグ用充填包装機７０Ｂは、横シール装置７６として、前述の９０°揺動プレート772上に設けた溶着溶断装置760に代えて、溶着溶断方向が上面視で交差するように配置した２つの溶着溶断装置760A、760Bをベースプレート764に直接的に設けたものである。この場合、２つの溶着溶断装置760A、760Bを交互に使用する。また、各溶着溶断装置760A、760Bによる横シールの形成方法としては、第１の横シールの形成時には、一方の溶着溶断装置760Aを用いて、図１の抽出バッグ用充填包装機７０の場合と同様に、シールヘッド７６ａを矢印ａのように斜め下方に走行させる。その後、矢印ｂのように、第１の横シールを形成する間の抽出バッグ用シート５の下方への走行距離をキャンセル位置に戻し走行させる。一方、他の溶着溶断装置760Bを用いて矢印ｃのようにシールヘッドを斜め下方に走行させることにより第２の横シールを形成し、その後、矢印ｄのように、第２の横シールを形成する間の抽出バッグ用シート５の加工への走行距離をキャンセル位置に戻し走行させる。 The extraction bag filling and packaging machine of the present invention can take various forms in addition to the above-described embodiments. For example, an extraction bag filling and packaging machine 70B shown in FIG. 6 replaces the welding fusing device 760 provided on the above-described 90 ° swing plate 772 as the horizontal sealing device 76, and the welding fusing directions intersect in a top view. The two welding fusing devices 760A and 760B arranged as described above are provided directly on the base plate 764. In this case, two welding fusing devices 760A and 760B are used alternately. In addition, as a method of forming the horizontal seal by each welding fusing device 760A, 760B, when forming the first horizontal seal, one welding fusing device 760A is used, and in the case of the filling bag packing machine 70 for the extraction bag of FIG. Similarly, the seal head 76a is caused to travel obliquely downward as indicated by an arrow a. Thereafter, as indicated by an arrow b, the travel distance downward of the extraction bag seat 5 during the formation of the first horizontal seal is returned to the cancel position for travel. On the other hand, the second horizontal seal is formed by running the seal head obliquely downward as indicated by arrow c using another welding fusing device 760B, and then the second horizontal seal is formed as indicated by arrow d. During this time, the travel distance for processing the extraction bag sheet 5 is returned to the cancel position and travels.

　このように９０°揺動プレート772を使用しない場合も、前述のように９０°揺動プレート772を使用する場合も、扁平手段としては、図７に示す扁平手段９０Ｂのように、２個の電磁石９２ａ、９２ｂを用い、第１の横シール方向の揺動プレート９１ａ、９１ｂに対向する実線の位置と、第２の横シール方向の揺動プレート９１ｃ、９１ｄに対向する破線の位置を交互にとらせ、その位置で電磁石９２ａ、９２ｂをＯＮとしてもよい。 In this way, both when the 90 ° swing plate 772 is not used and when the 90 ° swing plate 772 is used as described above, the flat means includes two flat means 90B as shown in FIG. Using the electromagnets 92a and 92b, the position of the solid line facing the swing plates 91a and 91b in the first lateral seal direction and the position of the broken line facing the swing plates 91c and 91d in the second lateral seal direction are alternated. The electromagnets 92a and 92b may be turned on at that position.

　この場合、抽出バッグ用充填包装機７０Ｂには、図２の上下動するベースプレート764上の９０°揺動プレート772とは別に、上下動しない９０°揺動プレートを設け、その９０°揺動プレートに電磁石９２ａ、９２ｂを固定することが、電磁石９２ａ、９２ｂと抽出バッグ用シート５との接触をなくす点から好ましい。 In this case, in addition to the 90 ° swing plate 772 on the base plate 764 that moves up and down in FIG. 2, the extraction bag filling and packaging machine 70B is provided with a 90 ° swing plate that does not move up and down. It is preferable to fix the electromagnets 92a and 92b to the extraction bag sheet 5 because contact between the electromagnets 92a and 92b and the extraction bag sheet 5 is eliminated.

　揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄを揺動させる駆動源としては、上述の電磁石に代えて、ガス噴射を使用することもできる。図８は、噴射孔９４ａ、９４ｂ、９４ｃ、９４ｄからのガス噴射で揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄを揺動させる扁平手段９０Ｃの模式図であり、図９はその断面図である。 As a drive source for swinging the swing plates 91a, 91b, 91c, 91d, gas injection can be used instead of the above-described electromagnet. FIG. 8 is a schematic view of flat means 90C for swinging the swing plates 91a, 91b, 91c, 91d by gas injection from the injection holes 94a, 94b, 94c, 94d, and FIG. 9 is a cross-sectional view thereof.

　なお、この扁平手段９０Ｃでは、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄは筒体７３の下端部に、その全厚を切り欠くことにより揺動可能に取り付けてあり、最も大きく揺動したときに揺動プレートの上端部がオーガ充填装置８０のファネルの管状の足８１に突き当たるようにしている。 In this flat means 90C, the swing plates 91a, 91b, 91c, 91d are attached to the lower end portion of the cylindrical body 73 so as to be swingable by cutting out the entire thickness thereof. The upper end portion of the swing plate abuts on the funnel tubular leg 81 of the auger filling device 80.

　この扁平手段９０Ｃは、筒体７３の壁厚の中にガス流路９５が形成されており、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄの上端部９１ｑに対向する位置に、ガス流路９５の末端がガスの噴射孔９４ａ、９４ｂ、９４ｃ、９４ｄとして形成されている。また、ガス噴射の有無を切り替えるバルブを有している（図示せず）。 In the flat means 90C, a gas flow path 95 is formed in the wall thickness of the cylindrical body 73, and the gas flow path 95 is located at a position facing the upper end portion 91q of the swing plates 91a, 91b, 91c, 91d. The ends are formed as gas injection holes 94a, 94b, 94c, 94d. Moreover, it has the valve which switches the presence or absence of gas injection (not shown).

　ここで、噴射するガスの種類としては、窒素、二酸化酸素、空気等を使用することができるが、製造した抽出バッグを外装材の中に窒素ガスと共に充填密封する場合には、その外装材内の窒素置換効率をあげるため、噴射ガスとして、窒素ガスを使用することが好ましい。 Here, nitrogen, oxygen dioxide, air, or the like can be used as the type of gas to be injected. However, when the manufactured extraction bag is filled and sealed with nitrogen gas in the exterior material, the interior of the exterior material is used. In order to increase the nitrogen substitution efficiency, it is preferable to use nitrogen gas as the injection gas.

　この扁平手段９０Ｃの使用方法としては、第１の横シールの直前においては、第１の横シール方向の揺動プレート９１ａ、９１ｂに、噴射孔９４ａ、９４ｂからガスを噴射することによりその揺動プレート９１ａ、９１ｂの上端部９１ｑを抽出バッグ用シート５の筒状体の軸Ｌ方向に揺動させる。これにより、揺動プレート９１ａ、９１ｂの下端部９１ｐが抽出バッグ用シート５の筒状体の外側方向に揺動し、抽出バッグ用シート５の筒状体は、第１の横シール方向に伸ばされ扁平となる。同様に第２の横シールの直前においては、第２の横シール方向の揺動プレート９１ｃ、９１ｄの上端部に、噴射孔９４ｃ、９４ｄからガスを噴射することにより、その揺動プレート９１ｃ、９１ｄの上端部を軸Ｌ方向に揺動させ、その下端部９１ｐを抽出バッグ用シート５の筒状体の外側方向に揺動させ、抽出バッグ用シート５の筒状体を第２の横シール方向に伸ばして扁平とする。 As a method of using the flat means 90C, immediately before the first lateral seal, the oscillation is performed by injecting gas from the injection holes 94a, 94b onto the oscillation plates 91a, 91b in the first lateral seal direction. The upper ends 91q of the plates 91a and 91b are swung in the direction of the axis L of the cylindrical body of the extraction bag seat 5. As a result, the lower end portions 91p of the swing plates 91a and 91b swing in the outer direction of the cylindrical body of the extraction bag seat 5, and the cylindrical body of the extraction bag seat 5 extends in the first lateral sealing direction. It becomes flat. Similarly, immediately before the second horizontal seal, by injecting gas from the injection holes 94c and 94d to the upper end portions of the swing plates 91c and 91d in the second horizontal seal direction, the swing plates 91c and 91d. The upper end portion of the extraction bag is swung in the direction of the axis L, the lower end portion 91p is swung in the outer direction of the tubular body of the extraction bag seat 5, and the tubular body of the extraction bag seat 5 is swung in the second lateral sealing direction. And flatten out.

　なお、この扁平手段９０Ｃでは、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄを揺動させる駆動源として、ガス噴射を使用するが、ガスを抽出バッグ用シート５に直接噴射するのではなく、揺動プレート９１ａ、９１ｂ、９１ｃ、９１ｄに対して噴射するので、抽出バッグ用シート５に直接噴射する場合のようにガスが噴射対象を通り抜けて扁平化が不十分になるという問題は生じない。また、噴射位置を揺動プレートの上端部としているので、抽出バッグ用シート５の筒状体内に充填された内容物がガス噴射により舞い上げられることはない。 In this flat means 90C, gas injection is used as a drive source for swinging the swing plates 91a, 91b, 91c, 91d. However, the gas is not sprayed directly onto the extraction bag sheet 5, but swings. Since it injects with respect to plate 91a, 91b, 91c, 91d, the problem that gas passes through the injection | pouring object and flattening becomes insufficient like the case where it injects directly to the sheet | seat 5 for extraction bags does not arise. Further, since the injection position is the upper end of the swing plate, the contents filled in the cylindrical body of the extraction bag sheet 5 are not lifted by the gas injection.

　本発明の充填包装機は、縦シール装置や横シール装置等には特に制限はなく、例えば、横シール装置としては、先端が先細に突出したシールヘッド７６ａを有する走行式の溶着溶断装置に代えて、シールヘッドの先端部が、横シールの形成幅に扁平に成形されている直押式の溶着溶断装置を使用してもよい。この場合には、横シールの形成時に、横シール装置７６を抽出バッグ用シート５の筒状体の幅方向に走行させることが不要となる。 The filling and packaging machine of the present invention is not particularly limited to a vertical sealing device, a horizontal sealing device, or the like. Thus, a direct-pressing welding fusing device in which the tip portion of the seal head is formed flat in the width of the horizontal seal may be used. In this case, it is not necessary to run the horizontal seal device 76 in the width direction of the tubular body of the extraction bag sheet 5 when forming the horizontal seal.

　本発明の抽出バッグ用シートの製造機械は、紅茶、緑茶、ハーブ等のティーバッグ、煮干し、鰹節等のだしの抽出バッグを生産ラインで連続的に製造するために有用である。 The machine for producing a sheet for an extraction bag of the present invention is useful for continuously producing tea bags such as black tea, green tea and herbs, and extraction bags for dried stock such as dried and dried bonito on the production line.
