Description

本発明は、ティーバッグなどのように、熱溶着方式で袋を作製しながら同時に茶葉等の被充填物を充填して製品化する製袋充填装置および製袋充填方法に関するものである。   The present invention relates to a bag making and filling apparatus and a bag making filling method for producing a product by filling a filling material such as tea leaves at the same time while producing a bag by a heat welding method such as a tea bag.

この種の製袋充填装置としては、例えば本出願人による特許文献１に記載のものが知られている。装置構成としては、装置本体の上部に計量部が設けられ、計量された被充填物を縦方向に延びる筒状のシュート部材を介して落下させ、既に縦シール部と下側の横シール部が形成されて袋状になってシュート部材の下方に位置する包装材内に充填し、所定量送った後、上側の横シール部を形成して切り離すようになっている。
包装材はシュート部材の外面を覆う筒状の状態で送られ、前段の袋の上側の横シール部の形成と同時に次段の袋の下側の横シール部が形成され、次段の袋に対する計量済みの被充填物の落下・充填が可能となり、これを繰り返すことにより、連続的にティーバッグ等を生産することができる。 As this type of bag making and filling apparatus, for example, the one described in Patent Document 1 by the present applicant is known. As a device configuration, a weighing unit is provided at the upper part of the device body, and the weighed material is dropped via a cylindrical chute member extending in the vertical direction, and the vertical seal portion and the lower horizontal seal portion are already provided. After being formed into a bag shape and filled in a packaging material positioned below the chute member and fed a predetermined amount, an upper lateral seal portion is formed and separated.

上記のように、特許文献１等に開示された従来方式では、下側の横シール部が形成された後、すなわち包装材が被充填物を収容可能な袋状に形成された後、計量された被充填物をシュート部材に投入して落下させるため、被充填物は、下側の横シール部のシールが終了したタイミングを開始基準として、シュート部材の縦方向の距離を落下することになる。
このため、下側の横シール部が形成された後、上記距離を被充填物が落下する時間が必ず必要となり、これがロスタイムとなって生産効率の低下を来たしていた。

Thus, it has the inclined surface 23c which guides to the vertical direction downward. The inclined surface 23c is formed in a smooth curved surface.
Since the pad 23 is connected to the rod-shaped member 21 via the end portion away from the center portion thereof, the rod-shaped member 21 is positioned in the charging chute 7 so as not to prevent the fall of the filling material as much as possible, that is, the charging chute 7 It can arrange | position in the inner peripheral surface vicinity.

次に、製袋充填装置１によって抽出用バッグとしてのティーバッグを製造する方法を説明する。
ロール状に巻き取られた包装材Ｓは繰出しホイール（図示せず）に装着され、その始端を繰出して図示しないガイドローラにガイドされ、投入シュート７の外面に沿うように案内される。
投入シュート７の外面を覆う状態で上側の対向ローラ対９によって送られ、その側縁同士が重ね合わされた状態で保持され筒状となる。
次いで超音波シール装置１１の超音波ホーン１１ａと受けロール装置１１ｂによって超音波シールされて縦シール部が形成される。 Next, a method for manufacturing a tea bag as an extraction bag by the bag making and filling apparatus 1 will be described.
The packaging material S wound up in a roll shape is mounted on a feeding wheel (not shown), fed out at its starting end, guided by a guide roller (not shown), and guided along the outer surface of the charging chute 7.
It is fed by the upper opposing roller pair 9 in a state of covering the outer surface of the charging chute 7, and is held in a state in which the side edges are overlapped to form a cylinder.
Next, ultrasonic sealing is performed by the ultrasonic horn 11a of the ultrasonic sealing device 11 and the receiving roll device 11b to form a vertical seal portion.

図４に示すように、筒状になった包装材Ｓは下側の対向ローラ対９によって送られ、その下端が投入シュート７の下側開口７ｃの下方における所定位置に来たところで、超音波シール装置４１の超音波ホーン４１ａと受けロール装置４１ｂとによってシールアンドカットされて、下側の横シール部Ｓｂ１が形成される。
この時、既に投入シュート７の下端部内方には計量された茶葉ＴＬが落下して貯留されている。下側の横シール部Ｓｂ１のシールアンドカットが完了すると、その信号を受けて開閉駆動部材２５が動作し、棒状部材２１を下方に移動させて投入シュート７の下側開口７ｃを開放する。
下側開口７ｃが開放されると、投入シュート７の下端部内方に貯留・待機していた茶葉ＴＬは、従来の落下距離Ｔａに比べて極めて短い高さＴｂ（図１参照）を落下し、袋状になった包装材Ｓの充填部Ｂｊに充填される。 As shown in FIG. 4, the cylindrical packaging material S is fed by the lower opposed roller pair 9, and the ultrasonic wave is received when the lower end of the packaging material S reaches a predetermined position below the lower opening 7 c of the input chute 7. Sealing and cutting is performed by the ultrasonic horn 41a and the receiving roll device 41b of the sealing device 41 to form the lower horizontal sealing portion Sb1.
At this time, the weighed tea leaves TL have already fallen and stored inside the lower end of the charging chute 7. When the seal and cut of the lower side seal portion Sb1 is completed, the opening / closing drive member 25 operates in response to the signal, and moves the bar-like member 21 downward to open the lower opening 7c of the closing chute 7.
When the lower opening 7c is opened, the tea leaves TL stored and waiting inside the lower end of the charging chute 7 fall at a height Tb (see FIG. 1) that is extremely shorter than the conventional drop distance Ta. The filling portion Bj of the packaging material S in a bag shape is filled.

図示しない制御手段により、開閉駆動部材２５が動作してから所定の時間が経過して充填が完了したと判断されると、開閉駆動部材２５が動作して棒状部材２１を上方に移動させ、投入シュート７の下側開口７ｃを閉じる。下側開口７ｃが閉じられると、次袋用の計量済みの茶葉ＴＬが投入シュート７に投入され、下端部内方に貯留される。
上記充填完了に伴って、包装材ＳがティーバッグＢ１の高さ寸法分のピッチで送られる。この送りが完了すると、超音波シール装置４１による前袋の上側の横シール部と次袋の下側の横シール部のシールアンドカットが開始される。図４はこの時の状態を示している。 When it is determined by a control means (not shown) that the filling has been completed after the opening / closing drive member 25 has been operated, the opening / closing drive member 25 is operated to move the rod-shaped member 21 upward, The lower opening 7c of the chute 7 is closed. When the lower opening 7c is closed, the weighed tea leaves TL for the next bag are put into the feeding chute 7 and stored in the lower end portion inside.
With the completion of the filling, the packaging material S is sent at a pitch corresponding to the height of the tea bag B1. When this feed is completed, the ultrasonic sealing device 41 starts sealing and cutting of the upper side seal portion of the front bag and the lower side seal portion of the next bag. FIG. 4 shows the state at this time.

図５に示すように、前袋の上側の横シール部Ｓｂ２と次袋の下側の横シール部Ｓｂ３のシールアンドカットが完了すると、前袋は切り離されて上記排出シュート１９から機外に排出されるとともに、上記と同様に投入シュート７の下側開口７ｃが開放され、貯留・待機していた茶葉ＴＬが高さＴｂを落下して次袋の充填部Ｂｊに充填される。
投入シュート７の下端部内方に貯留していた茶葉ＴＬは、パッド２３の傾斜面２３ｃによって径方向に拡がるように案内される。これにより、塊となって偏った位置に充填されることはなく、良好にバラケあるいはほぐされ、均一状態に分散・充填される。 As shown in FIG. 5, when the seal and cut of the upper side seal portion Sb2 of the front bag and the lower side seal portion Sb3 of the next bag is completed, the front bag is separated and discharged from the discharge chute 19 to the outside of the machine. At the same time, the lower opening 7c of the charging chute 7 is opened in the same manner as described above, and the tea leaves TL that have been stored and waiting fall down the height Tb and are filled in the filling portion Bj of the next bag.
The tea leaves TL stored inside the lower end of the charging chute 7 are guided by the inclined surface 23c of the pad 23 so as to expand in the radial direction. As a result, it is not filled in uneven positions as a lump, but is well separated or loosened and dispersed and filled in a uniform state.

図６は、製袋充填工程における本発明と従来方式との比較タイミングチャートである。図６（ａ）の「開」はシュート開閉手段１７による下側開口７ｃの開動作を、「閉」はその閉じ動作を示している。
図６に示すように、本発明では、投入シュート７の下端部内方に計量された茶葉を予め落下させて貯留し、待機させる時間を、送りと横シールの工程時間内に吸収させることができる。
すなわち、下側のシール部のシール終了を待たずに計量された茶葉を落下させて貯留することができる。
したがって、連続工程の中で実際に生じるのは、Ｔａよりもかなり低いＴｂの高さを落下する時間だけであり、従来方式に比べてロスタイムを大幅に低減することができる。
従来方式に比べて１袋毎に図６に符号Ｍで示すような時間短縮が可能となり、生産数が多ければ多い程その効率を向上させることができる。 FIG. 6 is a comparison timing chart of the present invention and the conventional method in the bag making and filling process. “A” in FIG. 6A indicates the opening operation of the lower opening 7c by the chute opening / closing means 17, and “CLOSE” indicates the closing operation.
As shown in FIG. 6, in the present invention, the tea leaves weighed in the lower end portion of the charging chute 7 are previously dropped and stored, and the waiting time can be absorbed within the process time of feeding and lateral sealing. .
That is, the measured tea leaves can be dropped and stored without waiting for completion of the seal of the lower seal portion.
Therefore, what actually occurs in the continuous process is only the time for dropping the height of Tb which is considerably lower than Ta, and the loss time can be greatly reduced as compared with the conventional method.
Compared to the conventional method, it is possible to shorten the time as indicated by the symbol M in FIG. 6 for each bag, and the greater the number of production, the higher the efficiency.

投入シュート７内で静電気が発生して棒状部材２１やパッド２３に茶葉が付着する懸念があるが、本実施形態ではこれを防止すべく、上記のように投入シュート７内で除電エアーを供給するようにしている。
除電エアーは直流式コロナ放電等により空気をイオン化したもので、この除電エアーを供給することにより、静電気は中和される。
これにより、投入シュート７内でシュート開閉手段１７が動作したり棒状部材２１等に茶葉が接触することによって発生する、茶葉が凝集したり棒状部材２１やパッド２３に付着して落下しなかったりするなどの静電気による不具合を良好に防止することができる。 There is a concern that static electricity is generated in the charging chute 7 and the tea leaves adhere to the rod-shaped member 21 or the pad 23. In this embodiment, in order to prevent this, the static elimination air is supplied in the charging chute 7 as described above. I am doing so.
The static elimination air is ionized air by DC corona discharge or the like, and the static electricity is neutralized by supplying this static elimination air.
As a result, the chute opening / closing means 17 operates in the charging chute 7 or the tea leaves are brought into contact with the bar-shaped member 21 or the like, and the tea leaves are not aggregated or adhered to the bar-shaped member 21 or the pad 23 and do not fall. It is possible to satisfactorily prevent malfunctions caused by static electricity.

以上、本発明の実施の形態について詳述してきたが、具体的構成は、この実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における設計の変更などがあっても発明に含まれる。
例えば、シュート開閉手段１７の構成において、パッド２３に代えて投入シュート７の下側開口７ｃにヒンジ構成の開閉自在な蓋を設け、ワイヤを介してこの蓋を小型モータ等の開閉駆動源で開閉するようにしてもよい。
また、縦シール手段及び横シール手段として超音波シール装置を用いたが、熱源を有する周知のヒートシール装置でシールしてもよい。
また、被充填物として茶葉を例示したが、線状体、粉状体、粒状体、破砕片等においても同様に実施することができる。 The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, in the configuration of the chute opening / closing means 17, a hinged openable / closable lid is provided in the lower opening 7 c of the closing chute 7 in place of the pad 23, and this lid is opened and closed by an open / close drive source such as a small motor via a wire. You may make it do.
Moreover, although the ultrasonic sealing apparatus was used as the vertical sealing means and the horizontal sealing means, sealing may be performed with a known heat sealing apparatus having a heat source.
Moreover, although the tea leaf was illustrated as a to-be-filled object, it can implement similarly in a linear body, a powdery body, a granular material, a crushing piece, etc.
