Description

本発明は、帯状包材を袋に成形しながらその袋に物品を充填して袋詰め商品を連続生産する製袋包装機に関し、物品包装の技術分野に属する。   The present invention relates to a bag making and packaging machine that continuously forms a bag-packed product by filling a bag with an article while forming a band-shaped packaging material into a bag, and belongs to the technical field of article packaging.

一般に、ポテトチップスのようなスナック菓子等の物品を包材で袋状に包装した商品を連続生産する製袋包装機は、チューブの周囲に帯状包材を巻き付けて筒状に曲成し、該筒状包材を搬送しながら重ね合わせ部を長手方向に縦シールしたのち、所定の間隔を置いて幅方向に横シール及び切断を行って製袋しつつ、その製袋過程において、例えば組合せ計量装置等から排出されて前記チューブに順次投入される物品を個々の袋に充填するものである。   In general, a bag making and packaging machine for continuously producing products in which articles such as snacks such as potato chips are packaged in a bag shape with a packaging material is wound around a tube by winding a belt-shaped packaging material, In the bag making process, for example, a combination weighing device, after vertically stacking the overlapping portion in the longitudinal direction while conveying the packaging material, making a bag by performing horizontal sealing and cutting in the width direction at a predetermined interval Each bag is filled with articles that are discharged from the gas etc. and sequentially put into the tube.

このような製袋包装機に備えられて筒状包材を横シールする横シール装置は、対接することによって前記包材を両側から挟み付けて溶着する一対のシールジョーを有しており、該シールジョーには、例えば特許文献１〜特許文献３に開示のものがある。   A lateral sealing device that is provided in such a bag making and packaging machine and laterally seals a cylindrical packaging material has a pair of sealing jaws that sandwich and weld the packaging material from both sides, Examples of the sealing jaw include those disclosed in Patent Documents 1 to 3.

まず、図１４に示すように、特許文献１に記載の一対のシールジョー６１０，６２０は、包材Ｆを挟み付ける対接面に、先端が平坦な複数の凸条６１１…６１１，６２１…６２１と比較的深い凹溝６１２…６１２，６２２…６２２とがそれぞれ対向して設けられている。また、各シールジョー６１０，６２０は、熱源としてヒータ６１３，６２３をそれぞれ内蔵している。   First, as shown in FIG. 14, the pair of sealing jaws 610 and 620 described in Patent Document 1 has a plurality of protrusions 611 to 611 to 621 that have flat tips on the contact surfaces that sandwich the packaging material F therebetween. And relatively deep concave grooves 612... 612, 622. Each of the sealing jaws 610 and 620 incorporates heaters 613 and 623 as heat sources.

これにより、横シール時には二点鎖線で示すように、両シールジョー６１０，６２０に設けられた凸条６１１…６１１，６２１…６２１同士が包材Ｆを挟み付けて加熱しつつ圧接し、包材Ｆは上下方向に複数箇所で線状に溶着されることになる。   Thereby, as shown by a two-dot chain line at the time of horizontal sealing, the protruding strips 611... 611, 621, 621 provided on both seal jaws 610, 620 are pressed against each other while sandwiching the packaging material F and heated, F is welded linearly at a plurality of locations in the vertical direction.

次に、図１５に示すように、特許文献２に記載の一対のシールジョー７１０，７２０は、包材Ｆを挟み付ける対接面が互いに噛合可能とされており、複数の略Ｖ字状の凸条７１１…７１１，７２１…７２１とＶ字状の凹溝７１２…７１２，７２２…７２２とが設けられている。その場合、一方（図例上左側）のシールジョー７１０の凸条７１１…７１１の先端は面取りされており、他方（図例上右側）のシールジョー７２０の凸条７２１…７２１の先端は略台形状とされている。また、一方のシールジョー７１０の凸条７１１…７１１及び凹溝７１２…７１２の傾斜角度は約９０度に設定されており、他方のシールジョー７２０の凸条７２１…７２１及び凹溝７２２…７２２の傾斜角度は約６０度に設定されている。そして、各シールジョー７１０，７２０は、熱源として上下一対のヒータ７１３，７１３，７２３，７２３をそれぞれ内蔵している。   Next, as shown in FIG. 15, the pair of sealing jaws 710 and 720 described in Patent Document 2 are configured such that the contact surfaces sandwiching the packaging material F can be engaged with each other, and a plurality of substantially V-shaped Ridges 711... 711, 721, 721, and V-shaped grooves 712, 712, 722, 722, 722 are provided. In this case, the tip of the convex strips 711... 711 of the seal jaw 710 on one side (left side in the figure) is chamfered, and the tip of the convex strips 721. It is made into a shape. In addition, the inclination angle of the convex strips 711... 711 and the concave grooves 712... 712 of one seal jaw 710 is set to about 90 degrees, and the convex strips 721 ... 721 and the concave grooves 722. The inclination angle is set to about 60 degrees. Each sealing jaw 710, 720 incorporates a pair of upper and lower heaters 713, 713, 723, 723 as heat sources.

これにより、横シール時には二点鎖線で示すように、一方のシールジョー７１０の傾斜角度が大きい凹溝７１２…７１２と他方のシールジョー７２０の傾斜角度が小さい凸条７２１…７２１とが包材Ｆを挟み付けて対接すると、符号ａ，ａ′で示す前記凹溝７１２…７１２の内部両側面と前記凸条７２１…７２１の略台形状の先端の両端部とで包材Ｆを加熱しつつ圧接し、包材Ｆは上下方向に複数箇所で線状に溶着されることになる。   As a result, as shown by a two-dot chain line at the time of horizontal sealing, the concave grooves 712... 712 having a large inclination angle of one sealing jaw 710 and the ridges 721. , While the packaging material F is heated with both inner side surfaces of the concave grooves 712... 712 indicated by symbols a and a ′ and both ends of the substantially trapezoidal tips of the convex strips 721. The wrapping material F is welded linearly at a plurality of locations in the vertical direction.

そして、図１６に示すように、特許文献３に記載の一対のシールジョー８１０，８２０は、包材Ｆを挟み付けるシールヘッド８１１とシリコンゴム板８２１とをそれぞれ備えている。前記シールヘッド８１１は、対接面が平坦面とされており、前記シリコンゴム板８２１は、対接面が包材Ｆ方向に突出する曲面とされている。   As shown in FIG. 16, the pair of sealing jaws 810 and 820 described in Patent Document 3 includes a sealing head 811 that sandwiches the packaging material F and a silicon rubber plate 821. The sealing head 811 has a flat contact surface, and the silicon rubber plate 821 has a curved surface protruding in the packaging material F direction.

これにより、横シール時には、二点鎖線で示すように、シールヘッド８１１とシリコンゴム板８２１とが包材Ｆを挟み付けて対接すると、柔軟性のあるシリコンゴム板８２１の突出した曲面が次第に上下方向に拡がるように変形しつつ他方のシールヘッド８１１との間で包材Ｆを圧接し、包材Ｆは面状に溶着されることになる。   As a result, at the time of horizontal sealing, as shown by a two-dot chain line, when the sealing head 811 and the silicon rubber plate 821 are in contact with each other with the packaging material F sandwiched therebetween, the curved surface of the flexible silicon rubber plate 821 is gradually projected. The packaging material F is pressed against the other seal head 811 while being deformed so as to expand in the vertical direction, and the packaging material F is welded in a planar shape.

ところで、充填する物品があられやピーナッツ等の場合、対接する一対のシールジョーによって挟み付けられて圧接される箇所の包材に、味付け用に前記物品に付着された通常石こうと同程度の硬さといわれる塩の結晶や硬い物品の破片、微粉等の粒子が噛み込まれ、袋の包材を損傷させてピンホールを生じさせることがある。   By the way, in the case where the article to be filled is a peanut or the like, the packaging material at the place to be sandwiched between the pair of sealing jaws that come into contact with each other and pressed is almost as hard as normal gypsum attached to the article for seasoning. Particles such as salt crystals, fragments of hard articles, fine powders, and the like may be caught, causing damage to the packaging material of the bag and generating pinholes.

例えば、前記特許文献１に記載のシールジョー６１０，６２０の場合には、図１４に二点鎖線で示すように、対向する一対の平坦かつ比較的上下方向の寸法が大きい凸条６１１，６２１間の包材Ｆ内に硬い粒子Ｘが挟み付けられると、近傍に逃げ場がないため該粒子Ｘは前記凸条６１１，６２１による捕捉から逃げようがなく、当該箇所の包材Ｆに粒子Ｘが噛み込まれるおそれがある。   For example, in the case of the sealing jaws 610 and 620 described in Patent Document 1, as shown by a two-dot chain line in FIG. 14, a pair of opposed flat and relatively large vertical dimensions between the protruding strips 611 and 621. When the hard particle X is sandwiched in the packaging material F, the particle X does not escape from being caught by the ridges 611 and 621 because there is no escape area in the vicinity, and the particle X bites into the packaging material F at the location. There is a risk of being caught.

また、前記特許文献２に記載のシールジョー７１０，７２０の場合には、図１５に拡大して二点鎖線で示すように、比較的深いＶ字状の凹溝７１２と略Ｖ字状の凸条７２１とによる符号ａで示す包材Ｆの圧接箇所に硬い粒子Ｘが挟み付けられると、同様に近傍に逃げ場がないため該粒子Ｘは前記凹溝７１２と凸条７２１とによる捕捉から逃げようがなく、当該箇所の包材Ｆに粒子Ｘが噛み込まれる可能性がある。   Further, in the case of the seal jaws 710 and 720 described in Patent Document 2, as shown in an enlarged double-dashed line in FIG. 15, a relatively deep V-shaped groove 712 and a substantially V-shaped protrusion. When the hard particle X is sandwiched in the pressure contact portion of the packaging material F indicated by the symbol a by the strip 721, the particle X similarly escapes from being captured by the concave groove 712 and the convex strip 721 because there is no escape area in the vicinity. And there is a possibility that the particles X are bitten into the packaging material F at the location.

また、前記特許文献３に記載のシールジョー８１０，８２０の場合には、図１６に二点鎖線で示すように、シールヘッド８１１とシリコンゴム板８２１とによる面状の圧接箇所に硬い粒子Ｘが挟み付けられると、前記特許文献１に記載のシールジョー６１０，６２０における場合と事情はほぼ同じであって、当該箇所の包材Ｆに粒子Ｘが噛み込まれるおそれがある。   Further, in the case of the sealing jaws 810 and 820 described in Patent Document 3, the hard particles X are present at the surface pressure contact portion between the sealing head 811 and the silicon rubber plate 821 as shown by a two-dot chain line in FIG. When sandwiched, the situation is almost the same as in the case of the seal jaws 610 and 620 described in Patent Document 1, and there is a possibility that the particles X are bitten by the packaging material F at the location.

そして、図１７に示すように、物品Ｍ…Ｍを充填した袋詰め商品Ｇの包材Ｆにおける非シール部Ｆ１と横シール部Ｆ２，Ｆ２との境界で硬い粒子Ｘの噛み込みが生じることにより、当該箇所の包材Ｆが損傷してピンホールが発生すると、該ピンホールを介して袋詰め商品Ｇ内部の空気や不活性ガス等の気体が漏出するというシール不良を招くことがある。なお、非シール部Ｆ１と横シール部Ｆ２，Ｆ２との境界以外、例えば横シール部Ｆ２，Ｆ２における上下方向の中央部で粒子Ｘの噛み込みがあったとしても、近傍に線状の溶着箇所が存在するので、ピンホールの発生には通常は直結しない。   And as shown in FIG. 17, the biting of the hard particles X occurs at the boundary between the non-seal portion F1 and the lateral seal portions F2, F2 in the packaging material F of the bag-filled product G filled with the articles M ... M. If the packaging material F at the location is damaged and a pinhole is generated, a sealing failure may occur in which air such as air or inert gas in the bag-filled product G leaks through the pinhole. In addition, even if there is a bite of the particle X in the vertical center of the horizontal seal portions F2 and F2 other than the boundary between the non-seal portion F1 and the horizontal seal portions F2 and F2, for example, a linear welded portion in the vicinity Therefore, pinholes are not usually directly connected.

そこで、本発明は、包材の横シール部における味付け用に物品に付着された硬い塩の結晶や硬い物品の微粉等の粒子の噛み込みを回避することにより、ピンホールの発生を防止可能な製袋包装機の提供を課題とする。   Therefore, the present invention can prevent the occurrence of pinholes by avoiding biting of particles such as hard salt crystals attached to the article for seasoning in the transverse seal portion of the packaging material or fine powder of the hard article. The issue is to provide a bag making and packaging machine.

前記課題を解決するため、本発明は次のように構成したことを特徴とする。   In order to solve the above problems, the present invention is configured as follows.

即ち、本発明は、帯状包材の両側縁部を重ね合わせて筒状に曲成し、該筒状包材を重ね合わせ部で長手方向に縦シールしたのち、該筒状包材を挟んで対接離反可能に配設された一対のシールジョーによって幅方向に横シールして袋に成形する製袋包装機であって、前記一対のシールジョーのうちの一方のシールジョーの対接面には平行に複数の凸条が設けられ、他方のシールジョーの対接面には、前記一方のシールジョーの対接面に設けられた凸条の対向位置に噛合可能に複数の凹溝が設けられていると共に、該凹溝の深さは前記凸条の高さより浅くされており、かつ、前記凸条は略台形とされ、該凸条と前記凹溝とは、凹溝の内部両側面と凸条の両側部との２箇所で前記筒状包材を挟み付けて圧接する形状とされていると共に、前記凸条と凹溝との間に前記筒状包材を挟み付けて圧接するとき、両端部の各圧接箇所の外側に該圧接箇所から開いた空間が設けられるように構成されていることを特徴とする。 That is, according to the present invention , both side edges of the belt-like packaging material are overlapped and bent into a cylindrical shape, and the cylindrical packaging material is longitudinally sealed in the longitudinal direction at the overlapping portion, and then sandwiched between the cylindrical packaging materials. A bag making and packaging machine that forms a bag by laterally sealing in a width direction by a pair of seal jaws arranged so as to be able to contact and separate from each other, on a contact surface of one of the pair of seal jaws A plurality of ridges are provided in parallel, and a plurality of concave grooves are provided on the contact surface of the other seal jaw so as to be able to mesh with the opposed positions of the ridges provided on the contact surface of the one seal jaw. In addition, the depth of the groove is shallower than the height of the ridge, and the ridge is substantially trapezoidal, and the ridge and the groove are on both inner side surfaces of the groove. And the shape of the cylindrical wrapping material sandwiched at two locations on both sides of the ridge and the ridge, When pressed by sandwiching the tubular packaging material between the grooves, and a space opened from piezoelectric contact point on the outside of each pressure contact points at both end portions are configured so that provided.

上記の構成により、本発明によれば、包材を両側から挟み付けて圧接することにより、幅方向に平行に延びる線状の複数の溶着箇所を有する横シール部を形成するとき、両端部の各圧接箇所の外側には該圧接箇所から開いた空間が設けられているので、例えば味付け用の塩が付着されたおかきやピーナッツ等の物品を包材内に充填する場合にも、硬い塩の結晶や硬い物品の微粉等の粒子は、この空間が存在するために、拘束されることなく包材内を逃げることができる。したがって、前記圧接箇所に硬い粒子が捕捉されて包材に噛み込むことが回避され、もって包材の損傷ひいてはピンホールの発生を防止可能となる。 With the above configuration, according to the present invention, by pressure contact sandwiching the packaging material from both sides, when forming the transverse seal portion with a linear multiple welding portions extending parallel to the width direction, both ends Since a space opened from the pressure contact point is provided on the outside of each pressure contact point, for example, when filling the packaging material with items such as rice crackers or peanuts to which seasoning salt is adhered, Particles such as crystals and fine powder of a hard article can escape from the packaging material without being constrained because of this space. Therefore, it is possible to prevent hard particles from being caught at the pressure contact portion and bite into the packaging material, thereby preventing the packaging material from being damaged and thus generating pinholes.

そして、本発明によれば、一方のシールジョーの対接面に設けられた凸条は略台形とされ、該凸条と他方のシールジョーの対接面に設けられた凹溝とは、一噛合箇所当り２箇所で包材を圧接することになる。 Then, according to the present invention, protrusions provided on the abutment surface of one of the sealing jaws is substantially trapezoidal, the grooves provided on the abutment surface of the ridge and the other sealing jaw is one The packaging material is pressed at two locations per meshing location.

その場合、例えば一噛合箇所当り一箇所で包材を圧接する場合に比較して、通常は包材の折り畳みが軽減される結果、包材にいたずらに大きな張力が作用することはない。したがって、仮に包材に硬い粒子の噛み込みが生じたとしても、該包材の損傷ひいてはピンホールの発生を防止する効果がある。   In this case, for example, as compared with the case where the packaging material is press-contacted at one place per meshing position, the folding of the packaging material is usually reduced, so that a large tension does not act on the packaging material. Therefore, even if hard particles are caught in the packaging material, there is an effect of preventing the packaging material from being damaged and thus generating pinholes.

また、凹溝の深さが深いと、粒子は該凹溝に対応する箇所の包材内に閉じ込められて、前記空間方向に逃げ難くなるが、本発明によれば、凹溝の深さを浅く設定することにより、この懸念が解消されるようになる。 Further, when the depth of the groove is deep, the particles are confined in the packaging material corresponding to the groove, making it difficult to escape in the spatial direction. According to the present invention, the depth of the groove is reduced. By setting it shallow, this concern will be resolved.

次に、本発明の実施の形態に係る製袋包装機について説明する。 Next, the bag making and packaging machine according to the embodiment of the present invention will be described.

図１に示すように、この製袋包装機１は縦型タイプのもので、本体１１に上流側から順に、包材ロールＲから帯状包材Ｆを繰出す繰出機構１２と、上部が漏斗形状とされると共に下部が円筒形状とされて、図示しない直上方の組合せ計量装置によって目標重量に計量された塩で味付けされたあられのような物品が投入されるチューブ１３と、該チューブ１３の比較的上部に取り付けられて、包材Ｆの左右両縁部を重ね合わせて筒状とするセーラ部材１４と、該チューブ１３の正面視で左右両側に配置されて、包材Ｆを該チューブ１３の左右両側面に押し付けながら下方に搬送する一対のプルダウンベルト機構（一方のみ示す）１５，１５と、該チューブ１３の前面に設けられて前記重ね合わせ部を長手方向に縦シールして筒状に成形する縦シール装置１６と、物品が収容された筒状包材Ｆを幅方向に横シールすると共に図示しない内蔵したカッタによって横シール部の中央で幅方向に切断する横シール装置１７とが組み付けられており、物品が充填された袋詰め商品Ｇを連続的に製造することができるようになっている。   As shown in FIG. 1, the bag making and packaging machine 1 is of a vertical type, and a feeding mechanism 12 that feeds a band-shaped packaging material F from a packaging material roll R to a main body 11 in order from the upstream side, and a funnel-shaped upper portion. Comparison between the tube 13 and the tube 13 into which the lower portion has a cylindrical shape and into which an article such as a bean seasoned with salt measured to a target weight by a combination weighing device directly above (not shown) is put. A sailor member 14 that is attached to the upper part and is formed in a cylindrical shape by superimposing the left and right edges of the packaging material F, and disposed on the left and right sides of the tube 13 in front view. A pair of pull-down belt mechanisms (only one is shown) 15 and 15 that are transported downward while being pressed against the left and right side surfaces, and are formed on the front surface of the tube 13 so that the overlapping portion is vertically sealed in the longitudinal direction to form a cylinder Vertical And a horizontal sealing device 17 that horizontally seals the cylindrical packaging material F containing articles in the width direction and cuts in the width direction at the center of the horizontal sealing portion by a built-in cutter (not shown). The bag-packed goods G filled with the articles can be continuously manufactured.

横シール装置１７は、筒状包材Ｆを挟み付けて加熱しつつ圧接することによって該包材Ｆを横シールする前後一対のシールジョー２０，３０を有しており、該シールジョー２０，３０は、図示しない回転機構によって二点鎖線で示すような側面視で略Ｄ字状の軌道を描くように移動する。   The lateral sealing device 17 includes a pair of front and rear sealing jaws 20 and 30 that laterally seal the packaging material F by sandwiching and heating the cylindrical packaging material F, and the sealing jaws 20 and 30. Is moved so as to draw a substantially D-shaped trajectory in a side view as indicated by a two-dot chain line by a rotation mechanism (not shown).

さらに詳しく説明すると、図２に示すように、横シール装置１７は、前記シールジョー２０，３０に加えて前後一対のシャッタ機構４０，４０と前後一対のしごき機構５０，５０とを備えている。なお、説明において「前」、「後」とあるのは、図中に矢印で示した方向に対応する。   More specifically, as shown in FIG. 2, the horizontal sealing device 17 includes a pair of front and rear shutter mechanisms 40 and 40 and a pair of front and rear ironing mechanisms 50 and 50 in addition to the sealing jaws 20 and 30. In the description, “front” and “rear” correspond to directions indicated by arrows in the drawing.

まず、シャッタ機構４０，４０は、シールジョー２０，３０に先んじて筒状包材Ｆを挟み付けることにより、該包材Ｆ内に投入される物品やその破片等の落下を規制し、前記シールジョー２０，３０による横シール時における物品やその破片等の噛み込みを抑制するものである。   First, the shutter mechanisms 40, 40 regulate the fall of articles or fragments thereof put into the packaging material F by sandwiching the cylindrical packaging material F ahead of the seal jaws 20, 30. It prevents biting of articles, fragments thereof, etc. during lateral sealing by the jaws 20 and 30.

ヒータ２１，３１を内蔵した左右（図例では奥方側と手前側）に延びるシールジョー２０，３０は、それぞれ一対の支持ブロック（手前側のみ示す）２２，２２，３２，３２に固定支持されており、該一対の支持ブロック２２，２２，３２，３２は、それぞれ連結板２３，３３で一体的に連結されている。   The seal jaws 20 and 30 extending in the right and left (in the illustrated example, the rear side and the front side) incorporating the heaters 21 and 31 are fixedly supported by a pair of support blocks (only the front side is shown) 22, 22, 32 and 32, respectively. The pair of support blocks 22, 22, 32, 32 are integrally connected by connecting plates 23, 33, respectively.

各シャッタ機構４０は、左右に延びる上部シャッタ板４１ａと下部シャッタ板４１ｂとを有している。上部シャッタ板４１ａは、側面視で略Ｖ字状とされ、基面と該基面から上方に折り曲げられて上部ほど筒状包材Ｆから離間する受け面とを有している。下部シャッタ板４１ｂは、側面視で略コ字状とされ、基面と該基面から下方に折り曲げられたのち反包材Ｆ方向に若干折り返された対接面とを有している。そして、両シャッタ板４１ａ，４１ｂはそれぞれの基面を介して結合されると共に、包材Ｆに接触する箇所に柔軟な緩衝シート４１ｃが貼着されている。なお、該緩衝シート４１ｃとしては、例えば面ファスナにおける柔らかいループ面側の素材が好ましく適用可能である。   Each shutter mechanism 40 has an upper shutter plate 41a and a lower shutter plate 41b extending in the left-right direction. The upper shutter plate 41a is substantially V-shaped in a side view, and has a base surface and a receiving surface that is bent upward from the base surface and is separated from the cylindrical packaging material F toward the top. The lower shutter plate 41b is substantially U-shaped in a side view, and has a base surface and a contact surface that is bent downward from the base surface and then slightly folded back in the anti-wrapping material F direction. The shutter plates 41a and 41b are coupled to each other through their respective base surfaces, and a flexible cushioning sheet 41c is attached to a portion that contacts the packaging material F. In addition, as the buffer sheet 41c, for example, a material on the soft loop surface side in the surface fastener is preferably applicable.

前記両シャッタ板４１ａ，４１ｂは、取付部材４２に支持されている。前記各連結板２３，３３には、それぞれ側面視で略Ｌ字状とされた固定部材４３が固定されており、該固定部材４３の上方端部にベース部材４４が取り付けられている。そして、該ベース部材４４と前記取付部材４２との間に、前記両シャッタ板４１ａ，４１ｂを進退可能に支持する一対の連結ロッド（手前側のみ示す）４５，４５が備えられており、また、該連結ロッド４５，４５を挟んで両側に、前記取付部材４２つまり両シャッタ板４１ａ，４１ｂを包材Ｆ方向に付勢するバネ４６，４６が介設されており、通常、各下部シャッタ板４１ｂの対接面は、各シールジョー２０，３０の対接面より包材Ｆ方向に突出している。   Both the shutter plates 41a and 41b are supported by a mounting member. A fixing member 43 that is substantially L-shaped in a side view is fixed to each of the connecting plates 23 and 33, and a base member 44 is attached to an upper end portion of the fixing member 43. Between the base member 44 and the mounting member 42, there are provided a pair of connecting rods 45 (shown only on the front side) 45 and 45 that support the shutter plates 41a and 41b so as to be able to advance and retreat. On both sides of the connecting rods 45, 45, springs 46, 46 for urging the mounting member 42, that is, both shutter plates 41a, 41b in the direction of the packaging material F are interposed, and usually each lower shutter plate 41b. These contact surfaces protrude from the contact surfaces of the seal jaws 20 and 30 in the direction of the packaging material F.

前記取付部材４２，４２の左右両端部に、補助ブロック（手前側のみ示す）４７ａ，４７ａ，４７ｂ，４７ｂが取り付けられており、前側シールジョー２０の補助ブロック４７ａ，４７ａにはウレタンゴム製の円柱状の緩衝部材４８ａ，４８ａが、後側シールジョー３０の補助ブロック４７ｂ，４７ｂにはボルト４８ｂ，４８ｂが突設されている。対向配置された緩衝部材４８ａとボルト４８ｂとは、包材Ｆを挟んで当接することにより、前後一対のシャッタ機構４０，４０間つまり上部シャッタ板４１ａ，４１ａ間及び下部シャッタ板４１ｂ，４１ｂ間の間隔を生成するもので、前記ボルト４８ｂのねじ込み位置の調整によって該間隔を適宜設定することができるようになっている。   Auxiliary blocks (shown only on the front side) 47a, 47a, 47b, 47b are attached to the left and right ends of the mounting members 42, 42. The auxiliary blocks 47a, 47a of the front seal jaw 20 are made of urethane rubber. Bolts 48b and 48b project from columnar buffer members 48a and 48a, and auxiliary blocks 47b and 47b of the rear seal jaw 30, respectively. The shock-absorbing member 48a and the bolt 48b that are arranged to face each other are in contact with each other with the packaging material F interposed therebetween, whereby a pair of front and rear shutter mechanisms 40 and 40, that is, between the upper shutter plates 41a and 41a and between the lower shutter plates 41b and 41b. The interval is generated, and the interval can be appropriately set by adjusting the screwing position of the bolt 48b.

次に、しごき機構５０，５０は、シールジョー２０，３０に先んじて筒状包材Ｆを挟み付けることにより、横シールされることになる該包材Ｆをしごいて該包材Ｆ内の物品を下方に移動させて、前記シールジョー２０，３０による横シール動作を円滑かつ良好に行なわせるためのものである。   Next, the squeezing mechanisms 50 and 50 sandwich the cylindrical packaging material F prior to the sealing jaws 20 and 30 to squeeze the packaging material F to be laterally sealed, By moving the article downward, the lateral sealing operation by the sealing jaws 20 and 30 is performed smoothly and satisfactorily.

各しごき機構５０は、左右に延びると共に側面視で先端ほど厚みが薄くなる形状とされたしごき板５１を有しており、該しごき板５１の包材Ｆに接触する先端部に前述したと同様の素材の緩衝シート５１ｃが貼着されている。   Each ironing mechanism 50 has a ironing plate 51 that extends in the left-right direction and has a thickness that decreases toward the tip when viewed from the side, and is similar to that described above at the tip of the ironing plate 51 that contacts the packaging material F. The buffer sheet 51c of the material is affixed.

各シールジョー２０，３０に備えられた各支持ブロック２２，３２の下面に取付部材５２が備えられている。前記しごき板５１の反包材Ｆ側に連結された左右一対の連結ロッド（手前側のみ示す）５３，５３が前記取付部材５２，５２内に部分的に嵌入されており、該連結ロッド５３，５３に前記しごき板５１を包材Ｆ方向に付勢するバネ５４，５４が外装されており、通常、各しごき板５１の先端は、各シールジョー２０，３０の対接面より包材Ｆ方向に突出している。   An attachment member 52 is provided on the lower surface of each support block 22, 32 provided in each seal jaw 20, 30. A pair of left and right connecting rods 53 (shown only on the front side) 53 and 53 connected to the anti-wrapping material F side of the ironing plate 51 are partially inserted into the mounting members 52 and 52, and the connecting rod 53, 53, springs 54 and 54 for urging the ironing plate 51 in the packaging material F direction are packaged. Normally, the leading ends of the ironing plates 51 are arranged in the packaging material F direction from the contact surfaces of the seal jaws 20 and 30, respectively. Protruding.

横シール動作に入ると、図３に示すように、シールジョー２０，３０と共に前記シャッタ機構４０，４０及びしごき機構５０，５０は筒状包材Ｆに接近し、下部シャッタ板４１ｂ，４１ｂ及びしごき板５１，５１は、シールジョー２０，３０に先んじて、筒状包材Ｆを挟み付けるようになる。   When the horizontal sealing operation is started, as shown in FIG. 3, the shutter mechanisms 40 and 40 and the ironing mechanisms 50 and 50 together with the seal jaws 20 and 30 approach the cylindrical packaging material F, and the lower shutter plates 41b and 41b and ironing are performed. The plates 51 and 51 sandwich the tubular packaging material F prior to the seal jaws 20 and 30.

すなわち、シャッタ機構４０，４０の下部シャッタ板４１ｂ，４１ｂで包材Ｆを挟み付けて、該包材Ｆ内に投入される物品Ｍ…Ｍやその破片等の落下を規制して、シールジョー２０，３０による横シール時における物品Ｍ…Ｍやその破片等の噛み込みを抑制することができると共に、上部シャッタ板４１ａ，４１ａで前記下部シャッタ板４１ｂ，４１ｂによる挟み付け位置より上方の物品Ｍ…Ｍが収容された包材Ｆ部分を良好に支持することができるようになる。   That is, the packaging material F is sandwiched by the lower shutter plates 41b and 41b of the shutter mechanisms 40 and 40, and the dropping of the articles M... , 30 can prevent the articles M... M and their fragments from being caught, and the upper shutter plates 41a and 41a can be used to prevent the articles M above the clamping position of the lower shutter plates 41b and 41b. The packaging material F portion in which M is accommodated can be favorably supported.

一方、しごき機構５０，５０のしごき板５１，５１で包材を挟み付けて、横シールされることになる該包材Ｆをしごいて該包材Ｆ内の物品Ｍ…Ｍを下方に移動させて、シールジョー２０，３０による横シール動作を円滑かつ良好に行なわせることができるようになる。そののち、太い二点鎖線で示すようにシールジョー２０，３０が包材Ｆを挟み付けて対接することにより、横シールが行なわれる。   On the other hand, the packaging material 51 is sandwiched between the squeezing plates 51 and 51 of the squeezing mechanisms 50 and 50, and the packaging material F to be laterally sealed is squeezed to move the articles M ... M in the packaging material F downward. Thus, the lateral sealing operation by the sealing jaws 20 and 30 can be performed smoothly and satisfactorily. After that, as shown by the thick two-dot chain line, the sealing jaws 20 and 30 sandwich the packaging material F and come into contact with each other, thereby performing the horizontal sealing.

その場合、シャッタ機構４０，４０における上部及び下部シャッタ板４１ａ，４１ａ，４１ｂ，４１ｂに緩衝シート４１ｃ，４１ｃを貼着したので、例えば硬い物品Ｍ…Ｍを挟み付け始めるときに、該物品Ｍ…Ｍやその破片等による包材Ｆの損傷を効果的に軽減することができる。また、しごき機構５０，５０においても、しごき板５１，５１に緩衝シート５１ｃ，５１ｃを貼着したので、同様に物品Ｍ…Ｍやその破片等による包材Ｆの損傷を良好に軽減することができる。   In this case, since the buffer sheets 41c and 41c are attached to the upper and lower shutter plates 41a, 41a, 41b and 41b in the shutter mechanisms 40 and 40, for example, when the hard article M. Damage to the packaging material F due to M or fragments thereof can be effectively reduced. Also, in the ironing mechanisms 50, 50, since the buffer sheets 51c, 51c are attached to the iron plates 51, 51, damage to the packaging material F due to the articles M ... M or fragments thereof can be reduced well. it can.

次に、本発明の特徴部分であるシールジョー２０，３０の構成について説明すると、図３において概ね点線の丸印で囲んだ部分、つまり図示しないカッタが出没するスリットを挟んで上下に分割された対接面の下側部分を拡大して図４に示すように、各シールジョー２０，３０の包材Ｆを挟み付ける対接面は特徴的な形状とされている。つまり、前側（図例上左側）シールジョー２０の対接面には、５つの比較的浅い円弧状の凹溝２０ａ…２０ａが設けられており、後側（図例上右側）シールジョー３０の対接面には、前記凹溝２０ａ…２０ａの対向位置に同数の略台形状の凸条３０ｂ…３０ｂが設けられており、これら凹溝２０ａ…２０ａと凸条３０ｂ…３０ｂとが互いに噛合可能とされている。その場合、一組の凹溝２０ａと凸条３０ｂとは、凹溝２０ａの内部両側面と凸条３０ｂの両側部との符号ａ，ａで示す２箇所で包材Ｆを挟み付けて圧接するようにそれらの形状が設定されている。   Next, the structure of the seal jaws 20 and 30 which are the characteristic part of the present invention will be described. In FIG. 3, the seal jaws 20 and 30 are divided into upper and lower parts with a portion surrounded by a dotted circle, that is, a slit in which a cutter (not shown) appears. As shown in FIG. 4 by enlarging the lower portion of the contact surface, the contact surface that sandwiches the packaging material F of each of the seal jaws 20 and 30 has a characteristic shape. That is, five relatively shallow arc-shaped concave grooves 20a... 20a are provided on the contact surface of the front side (left side in the figure) seal jaw 20, and the rear (right side in the figure) seal jaw 30 The contact surface is provided with the same number of substantially trapezoidal convex ridges 30b ... 30b at positions facing the concave grooves 20a ... 20a, and these concave grooves 20a ... 20a and ridges 30b ... 30b can mesh with each other. It is said that. In that case, the pair of concave grooves 20a and the ridges 30b are pressed against each other by sandwiching the packaging material F at two locations indicated by the symbols a and a between the inner side surfaces of the concave grooves 20a and the both side portions of the ridges 30b. So that their shape is set.

さらに、最下方の圧接箇所ａの下側には、該圧接箇所ａから開いた空間Ｓが設けられるように、前側シールジョー２０の対接面の下端部は角部が面取りされて丸味が形成され、後側シールジョー３０の対接面の下端部は角部が大きく切り欠かれている。   Further, the lower end portion of the contact surface of the front seal jaw 20 is chamfered at its lower end portion so that a roundness is formed so that a space S opened from the pressure contact location a is provided below the lowermost pressure contact location a. In addition, the lower end portion of the contact surface of the rear seal jaw 30 is largely cut off at the corner.

なお、シールジョー２０，３０の上下に分割された対接面の上側部分においては、最上方の圧接箇所の上側に、該圧接箇所から開いた空間が設けられるように構成されている点を除き、事情は前述した下側部分と同じであるので、説明を省略する。   It should be noted that the upper portion of the contact surface divided into the upper and lower portions of the seal jaws 20 and 30 is configured such that a space opened from the press contact location is provided above the uppermost press contact location. Since the situation is the same as that of the lower part described above, the description is omitted.

ここで、この製袋包装機１の作用について説明する。   Here, the effect | action of this bag making packaging machine 1 is demonstrated.

すなわち、図１に示したように、繰出機構１２から繰り出された帯状包材Ｆの左右両縁部が重ね合わされて筒状とされ、この重ね合わせ部が縦シール装置１６によって縦方向にシールされたのち、横シール装置１７によって物品Ｍ…Ｍが収容された筒状包材Ｆが幅方向にシールされると共に横シール部の中央で幅方向に切断されて、物品Ｍ…Ｍが充填された袋詰め商品Ｇが得られることになる。   That is, as shown in FIG. 1, the left and right edges of the belt-like packaging material F fed from the feeding mechanism 12 are overlapped to form a cylinder, and the overlapping portion is sealed in the vertical direction by the vertical sealing device 16. After that, the cylindrical packaging material F in which the articles M... M are accommodated by the lateral seal device 17 is sealed in the width direction and cut in the width direction at the center of the lateral seal portion, and the articles M. The bag-packed product G will be obtained.

その場合に、前述したシャッタ機構４０，４０及びしごき機構５０，５０に後続して、図４に一部を示した構成のシールジョー２０，３０で包材Ｆを両側から挟み付けて圧接することにより、幅方向に平行に延びる線状の複数の溶着箇所を有する横シール部を形成するとき、最下方の圧接箇所ａの下側には該圧接箇所ａから開いた空間Ｓが設けられているので、例えば味付け用の塩が付着されたおかき等の物品Ｍ…Ｍを包材Ｆ内に充填する場合に、硬い塩の結晶や硬い物品Ｍの微粉等の粒子Ｘは、この空間Ｓが存在するために、矢印ｂで示すように拘束されることなく包材Ｆを押し退けつつ逃げることができる。したがって、前記圧接箇所ａに硬い粒子Ｘが捕捉されて包材Ｆに噛み込むことが回避され、もって包材Ｆの損傷ひいてはピンホールの発生を防止可能となる。   In that case, following the shutter mechanisms 40 and 40 and the ironing mechanisms 50 and 50 described above, the packaging material F is clamped from both sides by the sealing jaws 20 and 30 partially shown in FIG. Thus, when forming a horizontal seal portion having a plurality of linear weld locations extending in parallel to the width direction, a space S opened from the press contact location a is provided below the lowest press contact location a. Therefore, for example, when filling the packaging material F with an article M... M with the salt for seasoning attached thereto, the particles S such as hard salt crystals and fine powder of the hard article M have this space S. Therefore, it is possible to escape while pushing away the packaging material F without being restrained as shown by the arrow b. Therefore, it is possible to avoid the hard particles X from being caught at the pressure contact point a and biting into the packaging material F, thereby preventing the packaging material F from being damaged and thus generating pinholes.

なお、粒子Ｘは、矢印ｂ方向とは反対の矢印ｂ′方向に逃げることもでき、仮に該粒子Ｘが上方の圧接箇所ａで噛み込まれたとしても、前述したように下方の圧接箇所ａが良好に圧接されるので、シール不良に直結することはない。   Note that the particle X can escape in the direction of the arrow b ′ opposite to the direction of the arrow b, and even if the particle X is caught in the upper pressure contact point a, the lower pressure contact point a as described above. Is not welded directly to the seal.

そして、後側シールジョー３０の対接面に設けられた凸条３０ｂ…３０ｂと前側シールジョー２０の対接面に設けられた凹溝２０ａ…２０ａとは、一噛合箇所当り符号ａ，ａで示す２箇所で包材Ｆを圧接することになる。   Further, the protrusions 30b... 30b provided on the contact surface of the rear seal jaw 30 and the concave grooves 20a... 20a provided on the contact surface of the front seal jaw 20 are represented by symbols a and a per meshing portion. The packaging material F is press-contacted at the two locations shown.

その場合、例えば一噛合箇所当り一箇所で包材Ｆを圧接する場合に比較して、通常は包材Ｆの折り畳みが軽減される結果、包材Ｆにいたずらに大きな張力が作用することはない。したがって、仮に包材Ｆに硬い粒子Ｘの噛み込みが生じたとしても、ピンホールの発生を防止する効果がある。   In this case, for example, as compared with the case where the packaging material F is press-contacted at one place per meshing position, the folding of the packaging material F is normally reduced, so that a large tension does not act on the packaging material F. . Therefore, even if the hard particles X are caught in the packaging material F, there is an effect of preventing the generation of pinholes.

なお、本実施の形態では、凹溝２０ａは円弧状とされていたが、略台形状であってもよく、その場合にも前述した作用と同様の作用が得られる。   In the present embodiment, the concave groove 20a has an arc shape. However, the groove 20a may have a substantially trapezoidal shape, and in this case, the same operation as described above can be obtained.

次に、本発明に関連するさまざまな形態について説明するが、その場合の製袋包装機や横シール装置は、いずれも前述した実施の形態に係る製袋包装機１や横シール装置１７と基本構成が共通し、ただシールジョーの構成のみが異なっている。 Next, various forms related to the present invention will be described. In that case, the bag making and packaging machine and the horizontal sealing device are basically the same as the bag making and packaging machine 1 and the horizontal sealing device 17 according to the embodiment described above. The configuration is common, only the configuration of the seal jaws is different.

まず、本発明に関連する第１の形態に係るシールジョーについて説明する。 First, the seal jaw according to the first embodiment related to the present invention will be described.

図５に示すように、前後一対のシールジョー１２０，１３０のうち、前側シールジョー１２０の対接面には、５つの比較的浅い円弧状の凹溝１２０ａ…１２０ａが設けられており、後側シールジョー１３０の対接面には、前記凹溝１２０ａ…１２０ａの対向位置に同数の円弧状の先端を有する凸条１３０ｂ…１３０ｂが設けられており、これら凹溝１２０ａ…１２０ａと凸条１３０ｂ…１３０ｂとが互いに噛合可能とされている。その場合、前記凹溝１２０ａと凸条１３０ｂとは、一噛合箇所当り凹溝１２０ａの底部と凸条１３０ｂの先端とで、符号ａで示す一箇所で包材Ｆを挟み付けて圧接するようにそれらの形状が設定されている。   As shown in FIG. 5, among the pair of front and rear seal jaws 120, 130, the contact surface of the front seal jaw 120 is provided with five relatively shallow arc-shaped concave grooves 120a ... 120a, and the rear side The contact surface of the seal jaw 130 is provided with ridges 130b... 130b having the same number of arcuate tips at positions opposed to the grooves 120a... 120a. The grooves 120a. 130b can be engaged with each other. In that case, the groove 120a and the ridge 130b are in pressure-contact with the bottom of the groove 120a and the tip of the ridge 130b at one meshing position, with the packaging material F sandwiched at one location indicated by symbol a. Their shape is set.

さらに、最下方の圧接箇所ａの下側には、該圧接箇所ａから開いた空間Ｓが設けられるように、前側シールジョー１２０の対接面の下端部は角部が面取りされて丸味が形成され、後側シールジョー１３０の対接面の下端部は角部が大きく切り欠かれている。   Furthermore, the lower end portion of the contact surface of the front seal jaw 120 is chamfered at the lower end portion of the contact surface of the front seal jaw 120 to form a roundness so that a space S opened from the pressure contact location a is provided below the lowermost pressure contact location a. In addition, the lower end portion of the contact surface of the rear seal jaw 130 has a large cutout corner.

これによれば、後側シールジョー１３０の対接面に設けられた凸条１３０ｂ…１３０ｂと前側シールジョー１２０の対接面に設けられた凹溝１２０ａ…１２０ａとが、一噛合箇所当り符号ａで示す一箇所で包材Ｆを圧接することになる。   According to this, the ridges 130b... 130b provided on the contact surface of the rear seal jaw 130 and the concave grooves 120a. The packaging material F is press-contacted at one place indicated by.

その場合、筒状包材Ｆの長手方向に沿う凸条１３０ｂの先端の寸法を小さく設定することにより、粒子Ｘは接近する該凸条１３０ｂの先端で効果的に弾かれて、前記空間Ｓが存在するために、圧接箇所ａから矢印ｂで示すように拘束されることなく包材Ｆを押し退けつつ速やかに逃げるようになる。また、凹溝１２０ａの深さが深いと、粒子Ｘは該凹溝１２０ａに対応する箇所の包材Ｆ内に閉じ込められて、前記空間Ｓ方向に逃げ難くなるが、凹溝１２０ａの深さを浅く設定することにより、この懸念が解消されるようになる。   In that case, by setting the size of the tip of the ridge 130b along the longitudinal direction of the cylindrical packaging material F to be small, the particles X are effectively repelled at the tip of the approaching ridge 130b, and the space S is formed. Since it exists, it comes to escape quickly from the press contact location a while pushing away the packaging material F without being restrained as shown by the arrow b. Further, when the depth of the concave groove 120a is deep, the particles X are trapped in the packaging material F at a location corresponding to the concave groove 120a and are difficult to escape in the direction of the space S, but the depth of the concave groove 120a is reduced. By setting it shallow, this concern will be resolved.

なお、粒子Ｘが矢印ｂ方向とは反対の矢印ｂ′方向に逃げることもでき、仮に該粒子Ｘが上方の圧接箇所ａで噛み込まれたとしても、下方の圧接箇所ａが良好に圧接されるので、シール不良に直結しないことは前述したとおりである。   The particle X can also escape in the direction of the arrow b ′ opposite to the direction of the arrow b. Even if the particle X is bitten by the upper pressure contact point a, the lower pressure contact point a is well pressed. Therefore, as described above, it is not directly connected to the seal failure.

次に、本発明に関連する第２の形態に係るシールジョーについて説明する。 Next, a seal jaw according to a second embodiment related to the present invention will be described.

図６に示すように、前後一対のシールジョー２２０，２３０のいずれの対接面にも、互いに対向するように５つの円弧状の先端を有する凸条２２０ｂ…２２０ｂ，２３０ｂ…２３０ｂが設けられており、これらの凸条２２０ｂ…２２０ｂ，２３０ｂ…２３０ｂ同士で符号ａ…ａで示す箇所で包材Ｆを挟み付けて圧接するようにそれらの形状が設定されている。   As shown in FIG. 6, convex surfaces 220b... 220b, 230b... 230b having five arcuate tips are provided on both contact surfaces of the pair of front and rear seal jaws 220 and 230 so as to face each other. These ridges 220b ... 220b, 230b ... 230b are set in shape so that the packaging material F is sandwiched and press-contacted at the locations indicated by the symbols a ... a.

さらに、最下方の圧接箇所ａの下側には、該圧接箇所ａから開いた空間Ｓが設けられるように、両シールジョー２２０，２３０の対接面の下端部は角部が大きく切り欠かれている。   Further, the lower end portion of the contact surfaces of the seal jaws 220 and 230 is notched at the corner so that a space S opened from the pressure contact location a is provided below the lowest pressure contact location a. ing.

これによれば、左側シールジョー２２０の対接面に設けられた凸条２２０ｂ…２２０ｂと右側シールジョー２３０の対接面に設けられた凸条２３０ｂ…２３０ｂとが包材Ｆを圧接することになる。   According to this, the ridges 220b... 220b provided on the contact surface of the left seal jaw 220 and the ridges 230b... 230b provided on the contact surface of the right seal jaw 230 press-contact the packaging material F. Become.

その場合、硬い粒子Ｘは接近する両側の凸条２２０ｂ，２３０ｂの先端で弾かれて、圧接箇所ａから矢印ｂ，ｂ′で示す方向に拘束されることなく包材Ｆを押し退けつつさらに速やかに逃げるようになる。しかも、両側の凸条２２０ｂ…２２０ｂ，２３０ｂ…２３０ｂ同士で包材Ｆを挟み付けるので、通常は包材Ｆの折り畳みがなくなる結果、包材Ｆにいたずらに大きな張力が作用するのを一層抑制することができる。   In that case, the hard particles X are bounced at the tips of the protruding ridges 220b and 230b on both sides approaching, and more rapidly while pushing away the packaging material F without being restrained in the direction indicated by the arrows b and b 'from the press contact point a. I will escape. Moreover, since the packaging material F is sandwiched between the ridges 220b... 220b, 230b... 230b on both sides, the packaging material F is usually not folded. be able to.

次に、本発明に関連する第３の形態に係るシールジョーについて説明する。 Next, a seal jaw according to a third embodiment related to the present invention will be described.

図７に示すように、前後一対のシールジョー３２０，３３０のうち、前側シールジョー３２０の対接面は平坦面３２０ｃとされており、後側シールジョー３３０の対接面には、５つの円弧状の先端を有する凸条３３０ｂ…３３０ｂが設けられており、平坦面３２０ｃと凸条３３０ｂの先端とにより、符号ａ…ａで示す箇所で包材Ｆを挟み付けて圧接するようになっている。   As shown in FIG. 7, of the pair of front and rear seal jaws 320, 330, the contact surface of the front seal jaw 320 is a flat surface 320 c, and the contact surface of the rear seal jaw 330 has five circles. Projections 330b... 330b having arcuate tips are provided, and the packaging material F is sandwiched and pressed by the flat surface 320c and the tips of the projections 330b at locations indicated by reference signs a. .

さらに、最下方の圧接箇所ａの下側には、該圧接箇所ａから開いた空間Ｓが設けられるように、前側シールジョー３２０の対接面の下端部は角部が面取りされて丸味が形成され、後側シールジョー３３０の対接面の下端部は角部が大きく切り欠かれている。   Furthermore, the lower end portion of the contact surface of the front seal jaw 320 is chamfered at its lower end portion so that a round space is formed so that a space S opened from the pressure contact location a is provided below the lowermost pressure contact location a. In addition, the lower end portion of the contact surface of the rear seal jaw 330 is largely cut off at the corner.

これによれば、後側シールジョー３３０の対接面に設けられた凸条３３０ｂ…３３０ｂと前側シールジョー３２０の平坦面３２０ｃとが包材Ｆを圧接することになる。   According to this, the ridges 330b... 330b provided on the contact surface of the rear seal jaw 330 and the flat surface 320c of the front seal jaw 320 come into pressure contact with the packaging material F.

その場合、前側シールジョー３２０の構成が単純化されており、低コスト化を維持することができる。その上で、前側シールジョー３２０の対接面には、硬い粒子Ｘを閉じ込める可能性のある凹溝が存在しないので、粒子Ｘの噛み込みはさらに効果的に防止される。   In that case, the configuration of the front seal jaw 320 is simplified, and the cost can be kept low. In addition, since there is no concave groove that may confine the hard particle X on the contact surface of the front seal jaw 320, the biting of the particle X is further effectively prevented.

しかも、後側シールジョー３３０の対接面に設けられた凸条３３０ｂ…３３０ｂと左側シールジョー３２０の平坦面３２０ｃとが包材Ｆを挟み付けるので、通常は包材Ｆの折り畳みがなくなる結果、包材Ｆにいたずらに大きな張力が作用するのを一層抑制することができる。   Moreover, since the ridges 330b... 330b provided on the contact surface of the rear seal jaw 330 and the flat surface 320c of the left seal jaw 320 sandwich the packaging material F, normally the folding of the packaging material F is eliminated. It is possible to further suppress the large tension acting on the packaging material F.

次に、本発明に関連する第４の形態に係るシールジョーについて説明する。 Next, a seal jaw according to a fourth embodiment related to the present invention will be described.

図８〜図１０に示すように、前後一対のシールジョー４２０，４３０はそれぞれ熱源としてのヒータ４２１，４３１を内蔵しており、そのうち、前側シールジョー４２０の対接面のほぼ全面にわたり、平坦面を有する厚みが約２ｍｍとされたシリコンゴム板４２４が備えられており、後側シールジョー４３０の上下に分割された各対接面には、前述した凸条１３０ｂ…１３０ｂに類似の先端が円弧状とされた５つの凸条（図１０に下側のもののみ示す）４３０ｂ…４３０ｂが設けられている。その場合、平坦なシリコンゴム板４２４と凸条４３０ｂ…４３０ｂの先端とで包材Ｆを挟み付けて符号ａ…ａで示す箇所で圧接するようになっている。   As shown in FIGS. 8 to 10, the pair of front and rear seal jaws 420 and 430 incorporate heaters 421 and 431 as heat sources, respectively, of which a flat surface over almost the entire contact surface of the front seal jaw 420. A silicon rubber plate 424 having a thickness of about 2 mm is provided, and a tip similar to the above-described protrusion 130b... 130b is circular on each of the contact surfaces divided up and down of the rear seal jaw 430. Five arcs (shown only in the lower side in FIG. 10) 430b... 430b are provided. In that case, the packaging material F is sandwiched between the flat silicon rubber plate 424 and the tips of the ridges 430b to 430b, and pressed at the locations indicated by the symbols a to a.

ところで、前側シールジョー４２０のように対接面のほぼ全面に熱伝導性の良くないシリコンゴム板４２４が備えられていると、通常、前側シールジョー４２０にヒータを備えなくても、ヒータ４３１を備えた後側シールジョー４３０と協働して包材Ｆを挟み付けたとき、該包材Ｆを溶着するには十分な熱が圧接箇所において確保されるが、包材Ｆの前後両側の温度が微妙に異なることがあり、その結果、横シール部にカールが生じ、見栄えが悪く商品価値を損なうことがある。そのような場合に、前側シールジョー４２０にもヒータ４２１が備えたことにより、対接時に挟み付けた包材Ｆの前後両側の温度をほぼ同じにすることができ、もってカールの発生が防止されるようになる。   By the way, when the silicon rubber plate 424 having poor heat conductivity is provided on almost the entire contact surface like the front seal jaw 420, the heater 431 is usually provided even if the front seal jaw 420 is not provided with a heater. When the packaging material F is sandwiched in cooperation with the rear seal jaw 430 provided, sufficient heat is secured in the pressure contact area to weld the packaging material F. May be slightly different. As a result, curling may occur in the horizontal seal portion, resulting in poor appearance and loss of commercial value. In such a case, since the front seal jaw 420 is also provided with the heater 421, the temperatures of the front and rear sides of the packaging material F sandwiched at the time of contact can be made substantially the same, thereby preventing the occurrence of curling. Become so.

前記シリコンゴム板４２４は正面視で矩形とされ、中央部にカッタが出没可能に矩形のスリット４２４ａが設けられている。このシリコンゴム板４２４は、側断面視でＬ字状の上下一対の固定金具４２５，４２５と複数のビス４２６…４２６とで前側シールジョー４２０の対接面に固定されている。該固定金具４２５，４２５は、シリコンゴム板４２４に図９において二点鎖線で示すように対接する後側シールジョー４３０に干渉しないように配設されている。   The silicon rubber plate 424 is rectangular when viewed from the front, and a rectangular slit 424a is provided at the center so that the cutter can protrude and retract. The silicon rubber plate 424 is fixed to the contact surface of the front seal jaw 420 with a pair of upper and lower fixing brackets 425, 425 and a plurality of screws 426,. The fixing brackets 425 and 425 are disposed so as not to interfere with the rear seal jaw 430 that contacts the silicon rubber plate 424 as shown by a two-dot chain line in FIG.

さらに、最下方の圧接箇所ａの下側には、該圧接箇所ａから開いた空間Ｓが設けられるように、後側シールジョー４３０の上側対接面の上端部及び下側対接面の下端部は、それぞれ角部が大きく切り欠かれている。   Furthermore, the upper end portion of the upper contact surface and the lower end of the lower contact surface of the rear seal jaw 430 are provided below the lowermost press contact location a so that a space S opened from the press contact location a is provided. Each part has a large cut-out corner.

これによれば、前記第３の形態における作用と同様の作用が得られるのに加えて、図１０に示すように、後側シールジョー４３０の対接面に設けられた凸条４３０ｂの先端と前側シールジョー４２０の対接面に備えられた平坦なシリコンゴム板４２４とが包材Ｆを挟み付けて対接しようとしたとき、仮に捕捉から逃げ切れなかった硬い粒子Ｘがあったとしても、シリコンゴム板４２４は凸条４３０ｂの先端に押圧されて該凸条４３０ｂの先端の両側方向に弾性的に変形するので、前記粒子Ｘはこの変形方向に導かれて矢印ｂ，ｂ’で示すように当該圧接箇所ａから逃げることができるようになる。前記粒子Ｘが矢印ｂ方向に逃げる場合、前記空間Ｓが存在するために、拘束されることなく包材Ｆを押し退けつつ逃げ易くなる。 According to this, in addition to obtaining the same operation as the operation in the third embodiment, as shown in FIG. 10, the tip of the ridge 430b provided on the contact surface of the rear seal jaw 430, Even if there is a hard particle X that could not escape from being caught when the flat silicon rubber plate 424 provided on the contact surface of the front seal jaw 420 is sandwiched with the packaging material F and tries to make contact, Since the rubber plate 424 is pressed against the tip of the ridge 430b and elastically deforms in both directions of the tip of the ridge 430b, the particles X are guided in this deformation direction as indicated by arrows b and b ′. It becomes possible to escape from the pressure contact point a. When the particle X escapes in the direction of the arrow b, the space S exists, so that it is easy to escape while pushing away the packaging material F without being restrained.

そして、両シールジョー４２０，４３０の対接面のほぼ全面において、圧接箇所ａ…ａにおける硬い粒子Ｘの噛み込みを防止することができ、横シール部のシール性の面でのさらなる品質向上を図ることができる。   In addition, almost all of the contact surfaces of the seal jaws 420 and 430 can prevent the hard particles X from being caught at the pressure contact points a ... a, and further improve the quality of the horizontal seal portion in terms of the sealing performance. Can be planned.

なお、シリコンゴム板４２４の厚みは１〜５ｍｍ程度のものが適用可能で、本形態の場合には約２ｍｍのものが好ましい。また、シリコンゴム板４２４に代えてフッ素ゴム板としてもよく、さらに適度な弾性、剛性、耐熱性等を兼ね備えた材質のものが好ましく適用可能である。 Note that a thickness of the silicon rubber plate 424 of about 1 to 5 mm is applicable, and in the case of this embodiment , a thickness of about 2 mm is preferable. Further, a fluorine rubber plate may be used in place of the silicon rubber plate 424, and a material having suitable elasticity, rigidity, heat resistance, etc. is preferably applicable.

次に、本発明に関連する第５の形態に係るシールジョーについて説明する。 Next, a seal jaw according to a fifth embodiment relating to the present invention will be described.

図１１〜図１３に示すように、前後一対のシールジョー５２０，５３０はそれぞれ熱源としてのヒータ５２１，５３１を内蔵しており、そのうち、前側シールジョー５２０の上下に分割された対接面には、少なくとも後側シールジョー５３０の上下に分割された対接面に設けられた、前述した第５の実施の形態における凸条４３０ｂ…４３０ｂと同じ複数の円弧状の先端を有した凸条５３０ｂ…５３０ｂのうちの上方端及び下方端のものの対向位置に、それぞれ平坦面を有するシリコンゴム板５２４，５２４が備えられている。   As shown in FIGS. 11 to 13, the pair of front and rear seal jaws 520 and 530 incorporate heaters 521 and 531 as heat sources, respectively. , Ridges 530b having a plurality of arcuate tips, which are the same as the ridges 430b ... 430b in the fifth embodiment described above, provided at least on the contact surfaces divided vertically in the rear seal jaw 530. Silicon rubber plates 524 and 524 each having a flat surface are provided at positions opposed to the upper end and the lower end of 530b.

前記各シリコンゴム板５２４は、側断面形状が矩形とされ、かつ前側シールジョー５２０に沿って延びており、前側シールジョー５２０の平坦面５２０ｃの上下角部が所定長さにわたって設けられた切り欠き部５２０ｃ′，５２０ｃ′に嵌め込まれた上で、同様に側断面形状が矩形とされて前側シールジョー５２０に沿って延びる固定部材５２５，５２５を介して、複数のボルト５２６…５２６で固定されている。その場合、図１２に示すように、前記固定部材５２５，５２５は、前側シールジョー５２０に対接する二点鎖線で示す後側シールジョー５３０に干渉しないように配設されている。   Each of the silicon rubber plates 524 has a rectangular cross-sectional shape, extends along the front seal jaw 520, and a notch in which the upper and lower corners of the flat surface 520c of the front seal jaw 520 are provided over a predetermined length. After being fitted into the portions 520c ′ and 520c ′, the side cross-sectional shape is similarly rectangular and is fixed by a plurality of bolts 526... 526 via fixing members 525 and 525 extending along the front seal jaw 520. Yes. In this case, as shown in FIG. 12, the fixing members 525 and 525 are disposed so as not to interfere with the rear seal jaw 530 indicated by a two-dot chain line in contact with the front seal jaw 520.

そして、前側シールジョー５２０の平坦なシリコンゴム板５２４，５２４と後側シールジョー５３０の上方端及び下方端の凸条５３０ｂ，５３０ｂの先端とで、符号ａで示す箇所で包材Ｆを挟み付けて圧接すると共に、上下方向の中間部では、前記シリコンゴム板５２４，５２４に代わって前側シールジョー５２０の平坦面５２０ｃと後側シールジョー５３０の凸条５３０ｂ…５３０ｂの先端とで、符号ａ…ａで示す箇所で包材Ｆを挟み付けて圧接するようになっている。   The packaging material F is sandwiched between the flat silicon rubber plates 524 and 524 of the front seal jaw 520 and the upper ends of the rear seal jaws 530 and the tips of the protrusions 530b and 530b at the lower ends at the locations indicated by the symbol a. In the middle portion in the vertical direction, the flat surface 520c of the front seal jaw 520 and the tips of the ridges 530b ... 530b of the rear seal jaw 530 are used in place of the silicon rubber plates 524, 524. The wrapping material F is sandwiched between the parts indicated by a and pressed.

さらに、前述した第４の形態におけると同様に、最下方の圧接箇所ａから開いた空間Ｓが設けられるように、後側シールジョー５３０の上側対接面の上端部及び下側対接面の下端部は、それぞれ角部が大きく切り欠かれている。 Further, as in the fourth embodiment described above, the upper end portion of the upper contact surface and the lower contact surface of the rear seal jaw 530 are provided so that a space S opened from the lowest pressure contact point a is provided. The lower end portion is largely cut off at the corner.

これによれば、同じく前記第３の形態における作用と同様の作用が得られるようになる。そして、図１３に示すように、後側シールジョー５３０の対接面に設けられた凸条５３０ｂの先端と前側シールジョー５２０の対接面の所定箇所に備えられた平坦なシリコンゴム板５２４とが包材Ｆを挟み付けて対接しようとしたとき、仮に捕捉から逃げ切れなかった硬い粒子Ｘがあったとしても、シリコンゴム板５２４は凸条５３０ｂの先端に押圧されて該凸条５３０ｂの先端の両側方向に弾性的に変形するので、前記粒子Ｘはこの変形方向に導かれて矢印ｂ，ｂ’で示すように当該圧接箇所ａから逃げることができるようになる。前記粒子Ｘが矢印ｂ方向に逃げる場合、前記空間Ｓが存在するために、拘束されることなく包材Ｆを押し退けつつ逃げ易くなる。 According to this, the same operation as that in the third embodiment can be obtained. Then, as shown in FIG. 13, a flat silicon rubber plate 524 provided at a predetermined portion of the front end of the protrusion 530 b provided on the contact surface of the rear seal jaw 530 and the contact surface of the front seal jaw 520, However, even if there are hard particles X that could not escape from the trapping when sandwiching the packaging material F, the silicon rubber plate 524 is pressed against the tip of the ridge 530b and the tip of the ridge 530b. Thus, the particles X are guided in this deformation direction and can escape from the pressure contact point a as indicated by arrows b and b ′. When the particle X escapes in the direction of the arrow b, the space S exists, so that it is easy to escape while pushing away the packaging material F without being restrained.

また、シリコンゴム板５２４，５２４を、少なくとも後側シールジョー５３０の対接面に設けられた凸条のうちの両端のものの対向位置、つまり硬い粒子Ｘの噛み込みが生じるとピンホール不良に直結する可能性のある圧接箇所に対応した位置に備えるようにすることにより、シリコンゴム部材５２４の使用量を必要最小限にとどめることができ、低コスト化が維持されるようになる。   Further, when the silicon rubber plates 524 and 524 are opposed to at least the opposite ends of the protrusions provided on the contact surface of the rear seal jaw 530, that is, when the hard particles X are caught, the pinhole defect is directly connected. By providing the position corresponding to the pressure contact location where there is a possibility of being used, the usage amount of the silicon rubber member 524 can be kept to the minimum necessary, and the cost reduction can be maintained.

そして、この場合にも、シリコンゴム板５２４に代えてフッ素ゴム板としてもよく、さらに適度な弾性、剛性、耐熱性等を兼ね備えた材質のものが好ましく適用可能である。   In this case, a fluorine rubber plate may be used instead of the silicon rubber plate 524, and a material having suitable elasticity, rigidity, heat resistance, etc. is preferably applicable.
