Description

本願発明は袋詰め包装方法及び装置に関する。より具体的には、袋の左右縁部を挟持する左右一対のグリッパを等間隔に複数組設け、これらグリッパで袋を袋口が上を向いた吊り下げ状態で保持しながら所定の平面軌道に沿って順次間欠的又は連続的に移送しながら、袋口の開口、被包装物の充填、スチーム脱気、袋口のシールなど、所定の包装処理を施す袋詰め包装方法及び装置に関する。   The present invention relates to a bagging and packaging method and apparatus. More specifically, a plurality of pairs of left and right grippers that sandwich the left and right edge portions of the bag are provided at equal intervals, and the bag is held in a predetermined plane orbit while being held in a suspended state with the bag mouth facing upward. The present invention relates to a bagging and packaging method and apparatus for performing a predetermined packaging process such as opening of a bag mouth, filling of an object to be packaged, steam deaeration, sealing of a bag mouth, etc., while being intermittently or continuously transferred along.

食品などの袋詰め包装を行う際に、被包装物を充填したのちに袋内の空気をスチームで置換して脱気するスチーム置換脱気を行う場合がある。例えば特開平９−９５３１１号にはそのようなスチーム置換脱気を行う装置が開示されている。スチーム置換脱気を行う場合には、被包装物が充填された袋をスチーム置換脱気工程のステーションに移動し、袋内にスチーム噴出ノズルを挿入し、袋の両側縁部を挟持する一対のグリッパを所定距離互いに遠ざけて袋口を緊張させた状態でスチームをノズル先端の噴出口から噴出させる。そして袋口を緊張させた状態のままでノズルを引き抜き、スチーム噴射も停止し、その袋口を緊張させた状態のままでシール工程を行うステーションへ袋を移動するようにしている。その際、通常スチーム噴出ノズルは袋内に挿入する挿入部を断面において扁平に形成されているノズルを使用するなどして、袋口を緊張させたときにノズルの左右縁部近くで袋口の両側のシートが離れて開いている部分が狭くなるようにし、また、袋口を緊張した状態のままでシールステーションへ移送してそのままシールするようにして、袋内へ外部から空気が入りこむのを防止するようにしている。   When performing bagging and packaging of foods or the like, steam replacement deaeration may be performed in which the air in the bag is replaced with steam after the package is filled. For example, Japanese Patent Laid-Open No. 9-95311 discloses an apparatus for performing such steam replacement deaeration. When performing steam replacement deaeration, the bag filled with the article to be packaged is moved to the station for the steam replacement deaeration process, a steam jet nozzle is inserted into the bag, and a pair of sandwiching both side edges of the bag Steam is ejected from the nozzle outlet at the tip of the nozzle while the grippers are kept apart from each other by a predetermined distance. Then, the nozzle is pulled out with the bag mouth kept in tension, the steam injection is stopped, and the bag is moved to the station where the sealing process is performed with the bag mouth kept in tension. At that time, the normal steam jet nozzle uses a nozzle that is formed flat in the cross section of the insertion portion to be inserted into the bag, and when the bag mouth is tensioned, the nozzle of the bag mouth is near the left and right edges of the nozzle. Make sure that the sheet on both sides is separated and the open part is narrowed, and that the bag mouth is kept in tension and is transferred to the sealing station and sealed as it is to prevent air from entering the bag from the outside. I try to prevent it.

ところが、袋内へ吹込まれたスチームにより後のシール工程で行われる袋口のシールに悪影響が生じる場合がある。すなわち、袋内へ噴射されたスチームは空気よりも比重が軽いために袋内で上昇し、袋の外へ流れる傾向にある。そのように上昇するスチームにより袋口のシール予定部をふくんだ袋の袋口の部分が温められて膨張し、袋口の縁部において、両側のシートが互いに離れる方向に傾倒して袋口がカール（湾曲）した状態になる場合がある。この状態で袋口のシール予定部をシールすると、シール予定部が折れ曲がったり、しわが寄ったりして見栄えが悪くなり、さらにはシール不良を引き起こす原因となる。 However, the steam blown into the bag may adversely affect the sealing of the bag mouth performed in the later sealing step. That is, since the steam injected into the bag has a specific gravity lighter than air, the steam rises in the bag and tends to flow out of the bag. The portion of the bag mouth of the bag containing the planned seal portion of the bag mouth is heated and expanded by the steam that rises in this way, and at the edge of the bag mouth, the sheets on both sides are tilted away from each other and the bag mouth May be curled (curved). If the planned seal portion of the bag mouth is sealed in this state, the planned seal portion will be bent or wrinkled, resulting in poor appearance and further causing a sealing failure.

従来このような問題に対処するためにカールした部分より下側でシールするなどしていたが、袋口縁部がシールされていないために製品の見栄えが悪くなり、また、密着していない袋口縁部に埃が入り込むなどして、好ましいものではなかった。また、シール幅が狭くなるところからシール強度に問題を生じる場合もあった。 Conventionally, in order to deal with such problems, sealing was performed below the curled part, but the bag mouth edge was not sealed, so the appearance of the product deteriorated, and the bag was not closely attached It was not preferable because dust entered the edge of the mouth. Further, there is a case where a problem occurs in the seal strength because the seal width becomes narrow.

特開平９−９５３１１号公報Japanese Patent Laid-Open No. 9-95311

本願発明は上記従来技術の問題点に鑑みなされたものであり、脱気工程で袋口縁部がカールした状態でもシールが適正に行えるようにし、或いはカールする度合いを低く抑えてシールに支障が生じないようにする袋詰め包装方法及び装置を提供する。 The present invention has been made in view of the above-mentioned problems of the prior art, so that the sealing can be performed properly even when the bag mouth edge is curled in the deaeration process, or the degree of curling is kept low, and the sealing is hindered. Provided is a bagging and packaging method and apparatus for preventing the occurrence.

A printer 6 is arranged at the printing station II, and the date of manufacture is printed on the bag B. Station III is an opening station, and the bag mouth of bag B is opened by a pair of opening suction cups 7. Station IV is a filling station that fills the bag B with the article to be packaged via the hopper 8. The deaeration station V is provided with a deaeration device 9 having a nozzle 10 connected to a steam source (not shown). The nozzle 10 is inserted into the bag B, and steam is ejected to replace and remove the air in the bag. I care. This will be further described later. In each of the stations VI and VII, a first sealing device 11 and a second sealing device 13 each having a pair of hot plates 12 and 14 arranged to face the planned sealing portion set in the bag mouth of the bag B are arranged. . Note that the second sealing device 13 is not necessarily required, and in each of the embodiments described later, the first sealing device 11 is used as a representative, and only the sealing device 11 will be described. Station VIII is a cooling and discharging station. After cooling the planned sealing portion with a pair of cooling plates 15, bag B is discharged onto product bag discharge chute 16.

次に図２乃至図４を参照して本願発明の第１の実施の形態を説明する。図２乃至４はガイド式袋口矯正装置２１（以下、単に「矯正装置２１」という。）により、脱気工程でスチームの影響により膨張して左右外側へ倒れた袋口を矯正する状態を示す図で、図２は脱気ステーションＶにおいてスチームを用いて袋内の空気を置換脱気された袋Ｂが矯正装置２１の近くへ移動してきた状態を示す図で、図３は矯正装置２１により矯正している途中の状態と矯正が終了した状態を示す図で、図４は図２，３におけるＡ−Ａ，Ｂ−Ｂ，Ｃ−Ｃ断面を示している。なお、本実施の形態では、袋口縁部ＢＭから袋の上下方向所定の幅の範囲がシール予定部Ｓとなっている。   Next, a first embodiment of the present invention will be described with reference to FIGS. 2 to 4 show a state in which a bag mouth that has expanded due to the influence of steam in the deaeration process and has fallen to the right and left sides is corrected by a guide-type bag mouth correction device 21 (hereinafter simply referred to as “correction device 21”). FIG. 2 is a view showing a state where the bag B, which has been degassed by replacing the air in the bag with steam at the deaeration station V, has moved closer to the correction device 21, and FIG. FIGS. 4A and 4B are cross-sectional views taken along lines AA, BB, and CC in FIGS. 2 and 3, respectively. In the present embodiment, the range of a predetermined width in the vertical direction of the bag from the bag edge BM is the scheduled seal portion S.

図２において、（イ）は平面図、（ロ）は正面図である。この矯正装置２１は、図１に示す脱気ステーションＶとシールステーションＶＩとの間に設けられ、一対の棒状のガイド部材２２を備えている。ガイド部材２２は、図から分る通り、移動してくる袋Ｂを保持するグリッパ３より上の位置で、袋Ｂの移動方向で所定の距離だけ延びている。そして、袋Ｂの移動方向で見て上流側から下流側に向かうにつれて上方へ延び、且つ互いの間隔が狭くなるように形成されている。すなわち図２に示すように、上下方向では、正常な状態でのシール予定部Ｓの下縁部より少し下の位置から袋口縁部ＢＭより少し上の位置までの範囲で延びており、間隔としては、入口側（図中左側）は移動してくる袋Ｂが確実に入り込むだけの広さを有し、出口側（図中右側）では、袋Ｂの厚みよりもわずかに広く、袋がスムーズに移動できる間隔となっている。 2A is a plan view, and FIG. 2B is a front view. The correction device 21 is provided between the deaeration station V and the seal station VI shown in FIG. 1 and includes a pair of rod-shaped guide members 22. As can be seen from the drawing, the guide member 22 extends a predetermined distance in the moving direction of the bag B at a position above the gripper 3 that holds the moving bag B. And it is formed so that it may extend upward and may mutually become narrow as it goes to the downstream from the upstream side seeing in the moving direction of the bag B. That is, as shown in FIG. 2, in the up-down direction, it extends in a range from a position slightly below the lower edge of the seal scheduled portion S in a normal state to a position slightly above the bag mouth edge BM, and the interval As for the entrance side (left side in the figure), the bag B that is moving is wide enough to enter, and the outlet side (right side in the figure) is slightly wider than the thickness of the bag B. The intervals are smooth.

袋Ｂがさらに進むと図３の（イ）及び図４（ロ）に示すように、袋Ｂの袋口縁部ＢＭは図中右側へ進むにつれて倒れた状態から次第に起こされて、袋口の両側のシートがきわめて近寄った状態まで矯正される。そして、袋Ｂがこの矯正装置２１を通過したときには袋口は全幅にわたって矯正されており、その状態でシールステーションＶＩに到達し、図示してない熱板によりシールされる。   When the bag B further advances, as shown in FIGS. 3 (a) and 4 (b), the bag mouth edge BM of the bag B is gradually raised from the collapsed state as it advances to the right side in the figure, The sheets on both sides are corrected to a very close state. When the bag B passes through the correction device 21, the bag mouth is corrected over the entire width, reaches the sealing station VI in this state, and is sealed by a hot plate (not shown).

上記の実施の形態によれば、仮に脱気工程においてスチームの影響により袋口がカールしても、袋口矯正工程においてそのカールが矯正され、その状態のままでシール工程でシールされるので、良好なシールを行うことができ、また、袋口縁部ＢＭまでシールすることができる。   According to the above embodiment, even if the bag mouth curls due to the influence of steam in the deaeration process, the curl is corrected in the bag mouth correction process and is sealed in the sealing process in that state. Good sealing can be performed, and the bag mouth edge BM can be sealed.

次に第２の実施の形態について図５、６を参照して説明する。この実施の形態での袋口矯正装置２５は、第１の実施の形態での一対の棒状のガイド部材２２に代えて一対のガイドローラ２７を使用している点で異なるのみで、脱気ステーションＶとシールステーションＶＩの間に設けられる点などの他の構成は第１の実施の形態と同じであるので、異なる点についてのみ説明する。 Next, a second embodiment will be described with reference to FIGS. The bag mouth correcting device 25 in this embodiment differs only in that a pair of guide rollers 27 is used instead of the pair of rod-shaped guide members 22 in the first embodiment, and a deaeration station. Since other configurations such as a point provided between V and the seal station VI are the same as those in the first embodiment, only different points will be described.

図５は第１の実施の形態の図２に対応し、（イ）は平面図、（ロ）は正面図である。図６は図３に対応し、（イ）は袋口の矯正されている状態を、（ロ）は矯正されてシール工程へ送られた状態を示している。前述のとおり、この実施の形態での矯正装置２５は、袋Ｂの両側に位置する一対のガイドローラ２７を備えており、それらは、袋詰め包装機１の基台（図示せず）に取付けられたローラ取付け軸２６に固定された回転軸２８に水平面内で回転自在に取付けられている。これらのガイドローラ２７は、図示のとおりグリッパ３より上方に位置し、シール部予定Ｓに対向する高さ位置に位置しており、二つのガイドローラ２７の間には袋Ｂの厚みよりわずかに広い隙間が設けられている。なお、ガイドローラ２７の厚み（上下方向寸法）はシール予定部の下縁部からわずかに下の位置から、袋口縁部ＢＭをわずかに超えた位置までの寸法としてもよい。上記構成から明らかなとおり、本実施の形態によれば、第１の実施の形態と同じ手順で袋口のカールが矯正される。 FIG. 5 corresponds to FIG. 2 of the first embodiment, (A) is a plan view, and (B) is a front view. FIG. 6 corresponds to FIG. 3, (A) shows a state where the bag mouth is corrected, and (B) shows a state where the bag mouth is corrected and sent to the sealing process. As described above, the correction device 25 in this embodiment includes a pair of guide rollers 27 located on both sides of the bag B, which are attached to a base (not shown) of the bag filling and packaging machine 1. The rotating shaft 28 fixed to the roller mounting shaft 26 is rotatably mounted in a horizontal plane. These guide rollers 27 are located above the gripper 3 as shown in the figure, and are located at a height position opposite to the seal portion schedule S. The gap between the two guide rollers 27 is slightly smaller than the thickness of the bag B. A wide gap is provided. The thickness (vertical dimension) of the guide roller 27 may be a dimension from a position slightly below the lower edge of the planned seal portion to a position slightly beyond the bag mouth edge BM. As is clear from the above configuration, according to the present embodiment, the curl of the bag mouth is corrected by the same procedure as in the first embodiment.

次に図７を参照して第３の実施の形態について説明する。この実施の形態では、脱気装置９に、スチーム置換脱気を行う際に袋口縁部ＢＭにカールが生じないように、或いは生じたとしてもそのカールが最少となるための構成が採用されている。図７において（イ）は袋Ｂが脱気ステーションＶへ移送されて停止し、ノズル１０の下端の噴出口側が袋Ｂ内へ挿入され、グリッパ３を互いに所定距離だけ互いに遠ざけて袋口を緊張させた状態を示している。ノズル１０は支持板３１に取付けられ、図示しない駆動源により支持板３１ごと上下動できるようになっている。そしてスチーム供給源３２に供給ライン３４を介して接続され、この供給ライン３４には切換え弁３３が設けられている。そしてこの脱気装置９には、ノズル１０が挿入された状態で袋Ｂのシール予定部Ｓを両側から押さえる一対の押さえ部材３５が設けられている。この一対の挟圧部材は例えばゴムなどの弾性材料で作られた、図示のような細長い断面方形の棒状の部材で構成されているが、素材及び形状はこれに限定はされず、ノズル１０の形状（本実施の形態では断面が扁平な形状になっているが、これに限定されない。）に倣ってノズル１０の外表面に両側から袋Ｂのシール予定部Ｓを密着させた状態で押さえ付けることができればよい。 Next, a third embodiment will be described with reference to FIG. In this embodiment, the deaeration device 9 is configured so that curl does not occur at the bag mouth edge BM when performing steam replacement deaeration, or the curl is minimized even if it occurs. ing. 7 (a), the bag B is transported to the deaeration station V and stopped, the lower end of the nozzle 10 is inserted into the bag B, the grippers 3 are moved away from each other by a predetermined distance, and the bag mouth is tensioned. It shows the state that was made to. The nozzle 10 is attached to a support plate 31 and can be moved up and down together with the support plate 31 by a drive source (not shown). The steam supply source 32 is connected via a supply line 34, and a switching valve 33 is provided in the supply line 34. The deaeration device 9 is provided with a pair of pressing members 35 that press the planned sealing portion S of the bag B from both sides with the nozzle 10 inserted. The pair of pinching members are made of a rod-like member having an elongated cross-sectional square shape as shown in the figure made of an elastic material such as rubber, but the material and shape are not limited to this, and the nozzle 10 According to the shape (in this embodiment, the cross section is a flat shape, but is not limited to this), the outer surface of the nozzle 10 is pressed with the planned seal portion S of the bag B in close contact from both sides. I can do it.

一対の押さえ部材３５は、図７（イ）に示される袋Ｂから離れた退避位置と、（ロ）に示される袋Ｂを介してノズル１０を両側から押さえ、この部分で袋Ｂのシール予定部Ｓをノズル１０の側面に密着させている押さえ位置との間で移動可能になっている。すなわち、図の（イ）の状態から押さえ部材３５を（ロ）に示される押さえ位置へ移動する。これにより袋Ｂの幅方向で中央部においてシール予定部Ｓがノズル１０の外表面に密着する（ノズル１０は通常袋の幅方向でその中央部に挿入される。）。従ってスチームが噴射されてもスチームはこの密着している部分には入り込むことができず、袋口はその中央部において膨張することが防止される。ノズル１０の両側ではスチームが袋Ｂの外へと流れるのでその部分において膨張する可能性があるが、中央部において膨張が抑えられるので、袋口全体としてのカールは小さく抑えられるので、後工程でのシールには支障を生じない。押さえ部材３５はノズル１０を袋Ｂから引き抜くのに先立ち、退避位置へ移動させられる。なお、ノズル１０からのスチームの噴射のタイミングは適宜決定される。噴射開始はノズル１０が袋Ｂに挿入されると同時、或いは挿入後、さらには押さえ部材３５で押さえたのちに開始することができる。また噴射の停止は、押さえ部材３５の退避位置への移動前、或いは移動後、さらにはノズル１０の袋Ｂから引き抜きと同時とすることができる。なお、押さえ部材３５は袋口のシール予定部Ｓを袋口縁部ＢＭまで確実にシールできるようにするために、シール部予定Ｓの下縁部より下の位置から袋口縁部ＢＭを上に越えた位置までの範囲で当接面を設けることが望ましい。 The pair of pressing members 35 press the nozzle 10 from both sides through the retracted position away from the bag B shown in FIG. 7A and the bag B shown in FIG. 7B, and the bag B is scheduled to be sealed at this portion. It can move between the pressing position where the portion S is in close contact with the side surface of the nozzle 10. That is, the pressing member 35 is moved from the state shown in (a) to the pressing position shown in (b). Thereby, the seal | sticker planned part S closely_contact | adheres to the outer surface of the nozzle 10 in the center part in the width direction of the bag B (The nozzle 10 is normally inserted in the center part in the width direction of a bag). Therefore, even when steam is sprayed, the steam cannot enter the close contact portion, and the bag mouth is prevented from expanding at the center portion. Since steam flows out of the bag B on both sides of the nozzle 10, there is a possibility of expansion at that portion, but since expansion is suppressed at the central portion, curl as the entire bag mouth can be suppressed small, This will not interfere with the seal. Prior to pulling out the nozzle 10 from the bag B, the pressing member 35 is moved to the retracted position. Note that the timing of jetting steam from the nozzle 10 is appropriately determined. The injection can be started simultaneously with the insertion of the nozzle 10 into the bag B or after the nozzle 10 is pressed with the pressing member 35 after the insertion. Further, the injection can be stopped before or after the pressing member 35 is moved to the retracted position, and at the same time as the nozzle 10 is pulled out from the bag B. In order to ensure that the pressure seal member 35 can seal the bag mouth seal portion S up to the bag mouth edge portion BM, the upper portion of the bag mouth edge portion BM is raised from a position below the lower edge portion of the seal portion schedule S. It is desirable to provide the contact surface in a range up to a position exceeding the distance.

上記の説明から明らかなとおり、この実施の形態では袋口のカールが生じないように、或いは生じても程度が最少となるようにされているので、後工程でのシール工程でシールする際にカールした部分が折り重なってシールされたりすることがなく、良好なシールを行うことができる。また、袋口の縁部まで確実にシールすることができる。 As is clear from the above description, in this embodiment, the curl of the bag mouth does not occur, or even if it occurs, the degree is minimized, so when sealing in the sealing process in the subsequent process The curled portion is not folded and sealed, and good sealing can be performed. Moreover, it can seal reliably to the edge part of a bag mouth.

次に図８を参照して第４の実施の形態を説明する。この実施の形態の特徴は、脱気工程においてノズル１０を袋内へ挿入したのちに、ノズル１０の両側において袋を部分的に仮シールする部分シール行うことにある。すなわち図８に示されるように、この実施の形態での脱気装置９は、ノズル１０の両側でシール予定部Ｓを部分的に仮シールする二組の仮シール用熱板４１と４２とを備えている。   Next, a fourth embodiment will be described with reference to FIG. A feature of this embodiment is that after the nozzle 10 is inserted into the bag in the degassing step, partial sealing is performed to partially temporarily seal the bag on both sides of the nozzle 10. That is, as shown in FIG. 8, the deaeration device 9 in this embodiment includes two sets of temporary sealing hot plates 41 and 42 that partially seal the planned sealing portion S on both sides of the nozzle 10. I have.

図８の（イ）は袋Ｂが脱気ステーションＶへ移送されて停止し、ノズル１０が挿入された状態を示している。この状態では仮シール用熱板４１、４２は退避位置にある。グリッパ３が移動して袋口を緊張させた後、図（ロ）に示すように仮シール用熱板４１，４２が互いに接近したシール位置へ移動し、シール予定部Ｓのノズル１０の両側の部分をシールする。熱板４１，４２の袋Ｂを挟み込む当接面は、図に示されるように袋口縁部ＢＭを挟んで上下にまたがっている。これによりシール予定部Ｓの中央部はノズル１０の外表面に密着するか、密着しなくても隙間がきわめて狭くなり、スチームがこの隙間に入り込むのが制限され、スチームの影響が小さくなる。また、ノズル１０の両側で仮シールがされているので、中央部の開口の幅が狭いために、その部分がカールしてもきわめて小さい。また、仮シールしている部分と袋の両側縁部との間の幅も狭くなるため、この部分でのカールも小さい。従ってこの状態でシールしても、カール部分が折り重なってシールされることはなく、良好なシールを行うことができる。また、袋口縁部ＢＭまで完全にシールすることができる。なお、この実施の形態では、スチームの噴出開始のタイミングは、仮シールを施した後が望ましい。   FIG. 8A shows a state in which the bag B is transferred to the deaeration station V and stopped, and the nozzle 10 is inserted. In this state, the temporary sealing hot plates 41 and 42 are in the retracted position. After the gripper 3 is moved and the bag mouth is tensioned, the temporary sealing hot plates 41 and 42 are moved to the sealing positions close to each other as shown in FIG. Seal the part. As shown in the drawing, the contact surface that sandwiches the bag B of the hot plates 41 and 42 extends over the bag mouth edge BM. As a result, the central portion of the planned seal portion S is in close contact with the outer surface of the nozzle 10 or even if it is not in close contact, the gap is extremely narrow, and the entry of steam into the gap is restricted, thereby reducing the influence of steam. In addition, since temporary sealing is performed on both sides of the nozzle 10, the width of the opening at the center is narrow, so even if the portion is curled, it is extremely small. Further, since the width between the temporarily sealed portion and the side edge portions of the bag is narrowed, the curl at this portion is also small. Therefore, even if sealing is performed in this state, the curled portion is not folded and sealed, and good sealing can be performed. Further, it is possible to completely seal up to the bag mouth edge BM. In this embodiment, it is desirable that the timing of the start of steam ejection is after provisional sealing.

次に図９，１０を参照して第５の実施の形態について説明する。この実施の形態では、スチーム置換脱気を行った後に袋口を冷却して、膨張してカールした袋口を元の状態に戻すようにしている。すなわちこの実施の形態では、脱気ステーションＶとシールステーションＶＩとの間に冷却ステーションが設けられており、そこに冷却装置４５が配置されている。図９は冷却装置４５を示す平面図、図１０は側面図であり、脱気ステーションＶにおいて脱気装置９によりスチーム置換脱気を施された袋Ｂがこの冷却装置４５の間を移動している状態を示している。 Next, a fifth embodiment will be described with reference to FIGS. In this embodiment, after the steam replacement deaeration is performed, the bag mouth is cooled, and the bag mouth that has been inflated and curled is returned to its original state. That is, in this embodiment, a cooling station is provided between the deaeration station V and the seal station VI, and the cooling device 45 is arranged there. FIG. 9 is a plan view showing the cooling device 45, and FIG. 10 is a side view. In the degassing station V, the bag B that has been subjected to steam replacement degassing by the degassing device 9 moves between the cooling devices 45. It shows the state.

冷却装置４５は、移動中の袋Ｂの両側で袋Ｂより多少上方に位置した一対の細長い冷却用ノズル４６を備えている。ノズル４６は袋Ｂの移動方向に沿って延びている。ノズル４６はその長手方向に所定の間隔で設けられた複数のガス噴出口４７を備え、配管４９を介して冷却ガス供給源４８に繋がっている。噴出口４７は図から分るとおり、斜め下方を向いて、袋Ｂの主としてカールしている袋口縁部ＢＭを含んだシール予定部Ｓに向けて冷却用のガスを吹付けるようになっている。このように冷却用のガスを吹付けることにより、膨張して傾いてカールしているシール予定部Ｓが冷却されて元のカールしていない状態に戻ることとなる。この状態でシールステーションＶＩに袋Ｂは移送され、シールされるので、良好なシールを行うことができる。冷却用ガスとしては空気などを使用できる。 The cooling device 45 includes a pair of elongated cooling nozzles 46 positioned slightly above the bag B on both sides of the moving bag B. The nozzle 46 extends along the moving direction of the bag B. The nozzle 46 includes a plurality of gas ejection ports 47 provided at predetermined intervals in the longitudinal direction, and is connected to a cooling gas supply source 48 through a pipe 49. As can be seen from the figure, the spout 47 is directed obliquely downward and sprays a cooling gas toward the planned sealing portion S including the bag mouth edge BM that is curled mainly of the bag B. Yes. By spraying the cooling gas in this manner, the planned seal portion S that is expanded and inclined and curled is cooled and returned to the original uncurled state. In this state, the bag B is transferred to the sealing station VI and sealed, so that good sealing can be performed. Air or the like can be used as the cooling gas.

次に図１１，１２を参照して第６の実施の形態について説明する。この実施の形態では、シール工程で使用される熱板を用いて袋口のカールを矯正する構成となっている。すなわちこの実施の形態では、シール装置１１の一対の熱板１２は、その当接面１２aの上縁部が、袋Ｂのカールしたシール予定部Ｓの上縁部（この実施の形態では袋口縁部ＢＭから所定の幅でシール予定部Ｓを設けるので、シール予定部Ｓの上縁部は袋口縁部ＢＭとなる。）より下の位置（図示した例では、袋口のカールしている部分の一番下の部分（袋幅のほぼ中央となる場合が多い。）にほぼ対応する位置にしてある。）で、袋Ｂを挟んで互いに所定の距離離れている待機位置（図１１（イ））に最初位置し、次いで互いに接近して互いの間隔が袋Ｂの厚みよりわずかに広い規制距離となる規制位置へ移動する（図１１（ロ））。次いでその間隔を維持したまま上方へ移動し（図１２（ハ））、袋Ｂのシール部予定Ｓに当接面１２aが対向するシール待機位置へ向かって移動し（図１２（ニ））、次いで互いに接近して袋Ｂのシール予定部Ｓを挟圧するシール位置へ移動してシール予定部Ｓをシールする。熱板１２が規制位置からシール待機位置へ移動するときに、カールして左右に傾いている袋口縁部ＢＭ或いはシール予定部Ｓを互いに近接して向かい合うように矯正し、その後にシールするので、良好なシールを行うことができる。なお、熱板１２の規制位置は図示の位置に限定されることはなく、熱板１２がシール待機位置へ移動する際にカールした袋口を矯正できる位置であればよい。また、上記の例では熱板１２を上方へ移動してシール待機位置へ移動させたが、グリッパ３を下方へ移動させ、袋Ｂを下へ移動するようにしてもよい。
Next, a sixth embodiment will be described with reference to FIGS. In this embodiment, the curl of the bag mouth is corrected using a hot plate used in the sealing step. That is, in this embodiment, the pair of heat plates 12 of the sealing device 11 has an upper edge portion of the contact surface 12a at the upper edge portion of the curled scheduled portion S curled on the bag B (in this embodiment, the bag mouth Since the planned sealing portion S is provided with a predetermined width from the edge BM, the upper edge of the planned sealing portion S becomes the bag mouth edge BM. In the illustrated example, the bag mouth curls 11 at a position corresponding to the lowermost part of the part (in many cases, approximately the center of the bag width). (B)), then move closer to each other and move to a regulation position where the distance between them is a regulation distance slightly wider than the thickness of the bag B (FIG. 11 (b)). Next, it moves upward while maintaining the interval (FIG. 12 (C)), and moves toward the seal standby position where the contact surface 12a faces the planned seal portion S of the bag B (FIG. 12 (D)). Next, they move closer to each other and move to a sealing position for clamping the planned sealing portion S of the bag B to seal the planned sealing portion S. When the hot plate 12 moves from the regulation position to the seal standby position, the bag mouth edge BM or the planned seal portion S that is curled and tilted to the left and right is corrected so as to face each other and then sealed. Good sealing can be performed. The restricting position of the hot plate 12 is not limited to the position shown in the figure, and any position that can correct the curled bag mouth when the hot plate 12 moves to the seal standby position may be used. In the above example, the hot plate 12 is moved upward and moved to the seal standby position. However, the gripper 3 may be moved downward and the bag B may be moved downward.
