The film supply unit 100b conveys the film F unwound from the film roll along a predetermined path and supplies it to the molding unit 10 of the bag making / packaging unit 100a (see FIG. 2).

（２－２）製袋包装ユニット
製袋包装ユニット１００ａは、図１～図３に示すように、成形部１０と、筒状部材２０と、プルダウンベルト機構３０と、縦シール機構４０と、ゲート機構５０と、横シール機構８０と、これらを支える支持フレーム４とを有する。 (2-2) Bag-making and packaging unit As shown in FIGS. 1 to 3, the bag-making and packaging unit 100a includes a molding portion 10, a tubular member 20, a pull-down belt mechanism 30, a vertical sealing mechanism 40, and a gate. It has a mechanism 50, a lateral sealing mechanism 80, and a support frame 4 for supporting them.

成形部１０、筒状部材２０、プルダウンベルト機構３０、縦シール機構４０、ゲート機構５０、及び横シール機構８０について概説する。 The molded portion 10, the tubular member 20, the pull-down belt mechanism 30, the vertical sealing mechanism 40, the gate mechanism 50, and the horizontal sealing mechanism 80 will be outlined.

成形部１０は、フィルム供給ユニット１００ｂから搬送されてくるシート状のフィルムＦを筒状に成形する。言い換えれば、成形部１０は、フィルム供給ユニット１００ｂから搬送されてくるシート状のフィルムＦから、筒状フィルムＦｔを成形する。筒状部材２０は、成形部１０の上方から、成形部１０の下方まで鉛直方向に延びるように配置される。筒状部材２０の上端部の開口は、組合せ計量器２が排出する物品Ｃを受け入れる。筒状部材２０の上端部の開口に投入された物品Ｃは、筒状部材２０の内部を落下搬送される。プルダウンベルト機構３０は、成形部１０が成形した筒状フィルムＦｔを下方に搬送する。縦シール機構４０は、筒状フィルムＦｔの重なり部分を縦方向にシールする。ゲート機構５０は、筒状部材２０の下端部に配置されている。ゲート機構５０は、筒状フィルムＦｔの底部に物品Ｃが直接落下することを避けるため、筒状部材２０の内部を落下してくる物品Ｃを受け止めて貯留し、所定のタイミングで物品Ｃを筒状フィルムＦｔの底部に落下させる。横シール機構８０は、下方に向かって搬送される筒状フィルムＦｔを横方向にシールすることで、袋Ｂの上下端を封止する。言い換えれば、横シール機構８０は、下方に向かって搬送される筒状フィルムＦｔを、筒状フィルムＦｔの搬送方向と交差する方向に沿ってシールすることで、袋Ｂの上下端を封止する。 The molding unit 10 molds the sheet-shaped film F conveyed from the film supply unit 100b into a cylindrical shape. In other words, the molding unit 10 molds the tubular film Ft from the sheet-shaped film F conveyed from the film supply unit 100b. The tubular member 20 is arranged so as to extend in the vertical direction from above the molding portion 10 to below the molding portion 10. The opening at the upper end of the tubular member 20 receives the article C discharged by the combination measuring instrument 2. The article C thrown into the opening at the upper end of the tubular member 20 is dropped and conveyed inside the tubular member 20. The pull-down belt mechanism 30 conveys the tubular film Ft formed by the forming unit 10 downward. The vertical sealing mechanism 40 seals the overlapping portion of the tubular film Ft in the vertical direction. The gate mechanism 50 is arranged at the lower end of the tubular member 20. The gate mechanism 50 receives and stores the article C falling inside the tubular member 20 in order to prevent the article C from falling directly on the bottom of the tubular film Ft, and stores the article C in a cylinder at a predetermined timing. Drop it on the bottom of the Cylinder Ft. The lateral sealing mechanism 80 seals the upper and lower ends of the bag B by laterally sealing the tubular film Ft conveyed downward. In other words, the lateral sealing mechanism 80 seals the upper and lower ends of the bag B by sealing the tubular film Ft conveyed downward along the direction intersecting the conveying direction of the tubular film Ft. ..

以下に、成形部１０、筒状部材２０、プルダウンベルト機構３０、縦シール機構４０、ゲート機構５０、及び横シール機構８０の詳細を説明する。 The details of the molded portion 10, the tubular member 20, the pull-down belt mechanism 30, the vertical sealing mechanism 40, the gate mechanism 50, and the horizontal sealing mechanism 80 will be described below.

（２－２－１）成形部
成形部１０は、フォーマ１２を主に含む。 (2-2-1) Molding part The molding part 10 mainly contains the former 12.

フォーマ１２は、筒状部材２０を取り囲むように配置されている。フォーマ１２は、シート状のフィルムＦを、左右方向に延びる幅方向に、フィルムＦの左端部および右端部が重なるように曲げて、筒状フィルムＦｔを成形する。 The former 12 is arranged so as to surround the tubular member 20. The former 12 bends the sheet-shaped film F so that the left end portion and the right end portion of the film F overlap each other in the width direction extending in the left-right direction to form the tubular film Ft.

（２－２－２）筒状部材
筒状部材２０は、上下方向に延び、上下端に開口を有する筒状の部材である。具体的には、筒状部材２０は、成形部１０のフォーマ１２の上方から、成形部１０のフォーマ１２の下方まで、鉛直方向に延びる。筒状部材２０は、少なくとも部分的に成形部１０の下方に配置される。限定するものではないが、成形部１０のフォーマ１２は、図示しないブラケットを介して、筒状部材２０に固定されている。 (2-2-2) Cylindrical member The tubular member 20 is a tubular member that extends in the vertical direction and has openings at the upper and lower ends. Specifically, the tubular member 20 extends in the vertical direction from above the former of the molding portion 10 to below the former of the molding portion 10. The tubular member 20 is at least partially arranged below the molded portion 10. Although not limited, the former 12 of the molding portion 10 is fixed to the tubular member 20 via a bracket (not shown).

筒状部材２０は、単一の部材で形成されてもよいし、複数の部材で形成されてもよい。 The tubular member 20 may be formed of a single member or may be formed of a plurality of members.

筒状部材２０の断面形状は、例えば円形である。添付した図面では、筒状部材２０の断面形状が円形であるとして描画している。ただし、筒状部材の断面形状は、円形に限定されるものではなく、他の形状、例えば楕円形状等であってもよい。筒状部材２０の断面形状は、例えば製袋包装機１００が製袋する袋Ｂの形状等に応じ、適宜設計されればよい。 The cross-sectional shape of the tubular member 20 is, for example, a circle. In the attached drawing, it is drawn assuming that the cross-sectional shape of the tubular member 20 is circular. However, the cross-sectional shape of the tubular member is not limited to a circular shape, and may be another shape such as an elliptical shape. The cross-sectional shape of the tubular member 20 may be appropriately designed according to, for example, the shape of the bag B produced by the bag making / packaging machine 100.

なお、以下の説明では、筒状部材２０の周方向という語を用いる場合がある。筒状部材２０の断面形状が円形である場合には、筒状部材２０の周方向は、筒状部材２０の円周方向である。一方、筒状部材２０の断面形状が円形でない場合には、平面視において筒状部材２０の内周面に沿う方向を、筒状部材２０の周方向と呼ぶ。 In the following description, the term "circumferential direction" of the tubular member 20 may be used. When the cross-sectional shape of the tubular member 20 is circular, the circumferential direction of the tubular member 20 is the circumferential direction of the tubular member 20. On the other hand, when the cross-sectional shape of the tubular member 20 is not circular, the direction along the inner peripheral surface of the tubular member 20 in a plan view is referred to as the circumferential direction of the tubular member 20.

また、以下で、筒状部材２０の中心という語を用いる場合がある。筒状部材２０の断面形状が円形である場合には、筒状部材２０の中心は、平面視における筒状部材２０の円の中心を意味する。一方、筒状部材２０の断面形状が円形でない場合には、平面視における筒状部材２０の重心を筒状部材２０の中心と呼ぶ。 Further, in the following, the term center of the tubular member 20 may be used. When the cross-sectional shape of the tubular member 20 is circular, the center of the tubular member 20 means the center of the circle of the tubular member 20 in a plan view. On the other hand, when the cross-sectional shape of the tubular member 20 is not circular, the center of gravity of the tubular member 20 in a plan view is referred to as the center of the tubular member 20.

筒状部材２０の上端の開口は、漏斗形状になっている。組合せ計量器２が製袋包装機１００に供給する物品Ｃは、図２に示すように、筒状部材２０の漏斗形状の上部の開口から投入され、筒状部材２０の内部を通過して落下する。つまり、物品Ｃは、筒状部材２０の内部を落下搬送される。 The opening at the upper end of the tubular member 20 has a funnel shape. As shown in FIG. 2, the article C supplied by the combination measuring instrument 2 to the bag making / packaging machine 100 is loaded from the upper opening of the funnel shape of the tubular member 20 and falls through the inside of the tubular member 20. do. That is, the article C is dropped and conveyed inside the tubular member 20.

（２－２－３）プルダウンベルト機構
プルダウンベルト機構３０は、筒状部材２０に巻き付いた筒状フィルムＦｔを吸着して下方に搬送する。プルダウンベルト機構３０は、筒状部材２０の左右両側に筒状部材２０を挟むように配置された一対のベルト３２を有する（図１参照）。ベルト３２は、吸着機能を有する。ベルト３２が、図示しないモータにより駆動される駆動ローラ３４と、従動ローラ３６とによって回転駆動されることで、ベルト３２によって吸着された筒状フィルムＦｔは下方に搬送される（図２参照）。 (2-2-3) Pull-down belt mechanism The pull-down belt mechanism 30 attracts the tubular film Ft wound around the tubular member 20 and conveys it downward. The pull-down belt mechanism 30 has a pair of belts 32 arranged so as to sandwich the tubular member 20 on both the left and right sides of the tubular member 20 (see FIG. 1). The belt 32 has a suction function. When the belt 32 is rotationally driven by a drive roller 34 driven by a motor (not shown) and a driven roller 36, the tubular film Ft adsorbed by the belt 32 is conveyed downward (see FIG. 2).

（２－２－４）縦シール機構
縦シール機構４０は、筒状部材２０に巻き付いた筒状フィルムＦｔの重なりあう部分を縦方向（ここでは鉛直方向）に沿ってシールする。 (2-2-4) Vertical Sealing Mechanism The vertical sealing mechanism 40 seals the overlapping portions of the tubular films Ft wound around the tubular member 20 along the vertical direction (here, the vertical direction).

縦シール機構４０は、筒状部材２０の正面側に配置されている（図２参照）。縦シール機構４０は、図示されないヒータと、筒状フィルムＦｔの重なり部分に接触するヒータベルト４２と、ヒータベルト４２を駆動する駆動機構（図示せず）と、を有する。ヒータは、ヒータベルト４２を加熱する。駆動機構は、ヒータベルト４２を筒状部材２０に近づくように、あるいは、筒状部材２０から遠ざかるように前後方向に駆動する。ヒータベルト４２が、駆動機構により筒状部材２０に近づくように駆動されることで、筒状部材２０に巻き付いた筒状フィルムＦｔの重なり部分が、ヒータベルト４２と筒状部材２０との間に挟まれる。縦シール機構４０は、加熱されたヒータベルト４２で、筒状フィルムＦｔの重なり部分を一定の圧力で筒状部材２０に押しつけることで、筒状フィルムＦｔの重なり部分を熱シールする。 The vertical sealing mechanism 40 is arranged on the front side of the cylindrical member 20 (see FIG. 2). The vertical seal mechanism 40 includes a heater (not shown), a heater belt 42 that comes into contact with an overlapping portion of the tubular film Ft, and a drive mechanism (not shown) that drives the heater belt 42. The heater heats the heater belt 42. The drive mechanism drives the heater belt 42 in the front-rear direction so as to approach the tubular member 20 or move away from the tubular member 20. By driving the heater belt 42 closer to the tubular member 20 by the drive mechanism, the overlapping portion of the tubular film Ft wound around the tubular member 20 is placed between the heater belt 42 and the tubular member 20. Sandwiched. The vertical sealing mechanism 40 heat-seals the overlapping portion of the tubular film Ft by pressing the overlapping portion of the tubular film Ft against the tubular member 20 with a heated heater belt 42.

（２－２－５）ゲート機構
ゲート機構５０について、図４～図９を更に参照して説明する。図４は、ゲート部材５２を開いた状態のゲート機構５０の概略側面図である。図５は、ゲート部材５２を閉じた状態のゲート機構５０の概略側面図である。図６は、ゲート部材５２を開いた状態のゲート機構５０の概略正面図である。図７は、ゲート機構５０の連結部６０の概略斜視図である。図８は、図６中の楕円VIIIで囲んだ部分の拡大図である。図９は、ゲート機構５０の連結部６０を上方から見た概略平面図である。図９では、平面図に合わせて、筒状部材２０の中心Ｏ側から各連結部６０を見た概略側面図を、概略平面図の上下に描画している。図９では、第１面６２ａ及び第２面６２ｂの場所が分かりやすいよう、第１面６２ａ及び第２面６２ｂにハッチングを付している。 (2-2-5) Gate Mechanism The gate mechanism 50 will be described with reference to FIGS. 4 to 9. FIG. 4 is a schematic side view of the gate mechanism 50 with the gate member 52 open. FIG. 5 is a schematic side view of the gate mechanism 50 in a state where the gate member 52 is closed. FIG. 6 is a schematic front view of the gate mechanism 50 with the gate member 52 open. FIG. 7 is a schematic perspective view of the connecting portion 60 of the gate mechanism 50. FIG. 8 is an enlarged view of the portion surrounded by the ellipse VIII in FIG. FIG. 9 is a schematic plan view of the connecting portion 60 of the gate mechanism 50 as viewed from above. In FIG. 9, a schematic side view of each connecting portion 60 seen from the center O side of the tubular member 20 is drawn above and below the schematic plan view in accordance with the plan view. In FIG. 9, the first surface 62a and the second surface 62b are hatched so that the locations of the first surface 62a and the second surface 62b can be easily understood.

ゲート機構５０は、図２のように、筒状部材２０の下端部に設けられている。ゲート機構５０は、所定のタイミングで物品Ｃの落下経路を塞ぎ、筒状部材２０の内部を落下してくる物品Ｃを受け止めて一旦貯留する。ゲート機構５０は、その後、所定のタイミングで、貯留した物品Ｃを筒状フィルムＦｔの底部に落下させる。要するに、ゲート機構５０は、物品Ｃが組合せ計量器２から、筒状フィルムＦｔの底部に物品Ｃが直接落下することを防止する。ゲート機構５０は、筒状フィルムＦｔ上に物品Ｃが直接落下し、筒状フィルムＦｔを傷付ける等の不具合を避けることができる。 The gate mechanism 50 is provided at the lower end of the tubular member 20 as shown in FIG. The gate mechanism 50 closes the fall path of the article C at a predetermined timing, receives the article C falling inside the tubular member 20, and temporarily stores the article C. The gate mechanism 50 then drops the stored article C onto the bottom of the tubular film Ft at a predetermined timing. In short, the gate mechanism 50 prevents the article C from falling directly from the combination measuring instrument 2 onto the bottom of the tubular film Ft. The gate mechanism 50 can avoid problems such as the article C falling directly on the tubular film Ft and damaging the tubular film Ft.

ゲート機構５０は、一対のゲート部材５２と、各ゲート部材５２と筒状部材２０とを連結する連結部６０と、一対のアーム５４と、アーム５４を駆動するアーム駆動機構５６と、を備える（図２～図４参照）。一対のアーム５４のそれぞれは、一対のゲート部材５２の一方と対応して設けられている（図２参照）。各アーム５４は、筒状フィルムＦｔを介して対応するゲート部材５２に当接し、ゲート部材５２を揺動させる部材である。 The gate mechanism 50 includes a pair of gate members 52, a connecting portion 60 that connects each gate member 52 and the cylindrical member 20, a pair of arms 54, and an arm drive mechanism 56 that drives the arms 54 ( (See FIGS. 2 to 4). Each of the pair of arms 54 is provided corresponding to one of the pair of gate members 52 (see FIG. 2). Each arm 54 is a member that abuts on the corresponding gate member 52 via the tubular film Ft and swings the gate member 52.

ゲート部材５２は、揺動部材の一例である。一対のゲート部材５２は、筒状部材２０の周方向に、互いに離間して配置されている。具体的には、ゲート部材５２は、筒状部材２０の中心Ｏを挟むように、互いに対向して配置されている。ゲート部材５２は、筒状部材２０の下端部に配置されている。ゲート部材５２は、連結部６０により、筒状部材２０に揺動可能に連結されている。一対のゲート部材５２は、その内面が互いに対向するように配置されている。本実施形態では、一対のゲート部材５２の一方は前方に配置され、一対のゲート部材５２の他方は後方に配置されている。 The gate member 52 is an example of a swing member. The pair of gate members 52 are arranged apart from each other in the circumferential direction of the tubular member 20. Specifically, the gate members 52 are arranged so as to face each other so as to sandwich the center O of the tubular member 20. The gate member 52 is arranged at the lower end of the tubular member 20. The gate member 52 is swingably connected to the tubular member 20 by a connecting portion 60. The pair of gate members 52 are arranged so that their inner surfaces face each other. In this embodiment, one of the pair of gate members 52 is arranged in the front, and the other of the pair of gate members 52 is arranged in the rear.

ゲート機構５０は、ゲート部材５２を筒状部材２０に対して揺動させることで、ゲート部材５２が開いた第１状態（図４参照）と、ゲート部材５２が閉じた第２状態（図５参照）と、を取ることが可能に構成されている。言い換えれば、ゲート部材５２は、筒状部材２０に対して揺動し、図４に示すような第１位置と、図５に示すような第２位置と、の間を移動可能に構成されている。第１位置に配置されているゲート部材５２は、物品Ｃの落下経路に張り出さない。具体的には、平面視において、第１位置に配置されているゲート部材５２は、筒状部材２０の内側には配置されない。または、平面視において、第１位置に配置されているゲート部材５２は、筒状部材２０の内側にはほとんど配置されない。一方、第２位置に配置されているゲート部材５２は、物品Ｃの落下経路に張り出している。具体的には、平面視において、第２位置に配置されているゲート部材５２は、筒状部材２０の内側に配置される。そして、一対のゲート部材５２は、第２位置に配置されている時に、落下してくる物品Ｃを下方に落下させずに受け止めるような形状・構造に形成されている。具体的には、本実施形態のゲート部材５２は、円筒形の筒状部材２０の内面形状と曲率が一致するような曲面状の部材である。また、本実施形態のゲート部材５２の下部は、図６のように、下方に向かって左右方向の幅が次第に小さくなるような形状を有する。そして、ゲート部材５２は、互いに第２位置に配置された時に、図５のように物品Ｃの落下経路を塞ぐように構成されている。ただし、ここで説明したゲート部材５２の形状・構造は一例に過ぎず、ゲート部材の形状・構造は、第２位置に配置された時に物品Ｃの落下経路を塞ぐように構成されていれば適宜決定されればよい。 The gate mechanism 50 swings the gate member 52 with respect to the cylindrical member 20 so that the gate member 52 is opened in the first state (see FIG. 4) and the gate member 52 is closed in the second state (FIG. 5). See) and is configured to be able to take. In other words, the gate member 52 swings with respect to the cylindrical member 20 and is configured to be movable between a first position as shown in FIG. 4 and a second position as shown in FIG. There is. The gate member 52 arranged at the first position does not project into the fall path of the article C. Specifically, in a plan view, the gate member 52 arranged at the first position is not arranged inside the tubular member 20. Alternatively, in a plan view, the gate member 52 arranged at the first position is hardly arranged inside the tubular member 20. On the other hand, the gate member 52 arranged at the second position overhangs the drop path of the article C. Specifically, in a plan view, the gate member 52 arranged at the second position is arranged inside the tubular member 20. The pair of gate members 52 are formed in a shape and structure so as to receive the falling article C without dropping it downward when it is arranged at the second position. Specifically, the gate member 52 of the present embodiment is a curved member having a curvature that matches the inner surface shape of the cylindrical tubular member 20. Further, as shown in FIG. 6, the lower portion of the gate member 52 of the present embodiment has a shape such that the width in the left-right direction gradually decreases toward the lower side. The gate members 52 are configured to block the fall path of the article C as shown in FIG. 5 when they are arranged at the second positions of each other. However, the shape / structure of the gate member 52 described here is only an example, and the shape / structure of the gate member is appropriate as long as it is configured to block the fall path of the article C when it is arranged at the second position. It should be decided.

アーム５４は、アーム駆動機構５６により駆動されて前後方向に移動する部材である。具体的には、アーム５４は、アーム駆動機構５６により駆動されて、対応するゲート部材５２に近づいて、筒状フィルムＦｔを介してゲート部材５２に接触するゲート部材閉鎖位置と、対応するゲート部材５２から離れて、ゲート部材５２に接触しないゲート部材開放位置との間を移動する。ゲート部材閉鎖位置に移動したアーム５４は、例えば、対応するゲート部材５２の下部（下端部の近傍）に接触する。 The arm 54 is a member that is driven by the arm drive mechanism 56 and moves in the front-rear direction. Specifically, the arm 54 is driven by the arm drive mechanism 56, approaches the corresponding gate member 52, and comes into contact with the gate member 52 via the tubular film Ft, and the corresponding gate member. It moves away from the gate member 52 to a gate member open position that does not come into contact with the gate member 52. The arm 54 that has moved to the gate member closed position comes into contact with, for example, the lower portion (near the lower end portion) of the corresponding gate member 52.

一対のアーム５４のそれぞれがゲート部材開放位置にあるとき、ゲート部材５２は第１位置に配置され、ゲート機構５０はゲート部材５２が開いた第１状態になる。なお、一対のアーム５４のそれぞれがゲート部材開放位置にあるとき、ゲート部材５２が第１位置に確実に配置されやすくするため、ゲート機構５０には、ゲート部材５２を第１位置に付勢する弾性部材（例えばバネ、図示省略）が設けられてもよい。一対のアーム５４のそれぞれがゲート部材閉鎖位置に移動するとき、一対のアーム５４のそれぞれは、筒状フィルムＦｔを介して対応するゲート部材５２に接触し、ゲート部材５２は第２位置に移動し、ゲート機構５０はゲート部材５２が閉じた第２状態（図５参照）なる。 When each of the pair of arms 54 is in the gate member open position, the gate member 52 is arranged in the first position, and the gate mechanism 50 is in the first state in which the gate member 52 is open. When each of the pair of arms 54 is in the gate member open position, the gate member 52 is urged to the first position in the gate mechanism 50 so that the gate member 52 can be reliably arranged in the first position. An elastic member (eg, a spring, not shown) may be provided. When each of the pair of arms 54 moves to the gate member closed position, each of the pair of arms 54 contacts the corresponding gate member 52 via the tubular film Ft, and the gate member 52 moves to the second position. The gate mechanism 50 is in a second state (see FIG. 5) in which the gate member 52 is closed.

アーム５４を駆動するアーム駆動機構５６は、例えばエアシリンダである。ただし、アーム駆動機構５６の種類は、エアシリンダに限定されるものではなく、モータ等、エアシリンダとは別の種類の駆動機構であってもよい。 The arm drive mechanism 56 that drives the arm 54 is, for example, an air cylinder. However, the type of the arm drive mechanism 56 is not limited to the air cylinder, and may be a drive mechanism of a different type from the air cylinder such as a motor.

連結部６０は、筒状部材２０の下端部に、筒状部材２０の内部側に張り出すように取り付けられている。言い換えれば、連結部６０は、筒状部材２０の内面よりも、筒状部材２０の中心Ｏ側に配置されるよう、筒状部材２０の下端部に取り付けられている。 The connecting portion 60 is attached to the lower end portion of the tubular member 20 so as to project toward the inside of the tubular member 20. In other words, the connecting portion 60 is attached to the lower end portion of the tubular member 20 so as to be arranged on the center O side of the tubular member 20 with respect to the inner surface of the tubular member 20.

連結部６０は、ゲート部材５２を筒状部材２０に対して揺動可能に連結している。具体的には、連結部６０は、ヒンジ機構６８を含む。ヒンジ機構６８は、筒状部材２０の下端部と、ゲート部材５２の上端部に固定された連結部材６６とを連結し、ゲート部材５２を筒状部材２０に対して前後方向に揺動可能に支持する。なお、連結部６０は、ヒンジ機構６８を覆うよう、ヒンジ機構６８の上方を覆う上面６２と、上面６２から下方に延び、ヒンジ機構６８の側方を覆う側面６４と、を有する。側面６４は、略鉛直面である。 The connecting portion 60 connects the gate member 52 to the cylindrical member 20 so as to be swingable. Specifically, the connecting portion 60 includes a hinge mechanism 68. The hinge mechanism 68 connects the lower end portion of the tubular member 20 and the connecting member 66 fixed to the upper end portion of the gate member 52 so that the gate member 52 can swing in the front-rear direction with respect to the tubular member 20. To support. The connecting portion 60 has an upper surface 62 that covers the upper part of the hinge mechanism 68 so as to cover the hinge mechanism 68, and a side surface 64 that extends downward from the upper surface 62 and covers the sides of the hinge mechanism 68. The side surface 64 is a substantially vertical face.

各連結部６０の上面６２の形状について説明する。 The shape of the upper surface 62 of each connecting portion 60 will be described.

本実施形態の連結部６０の上面６２は、第１面６２ａと、第１面６２ａと交差する第２面６２ｂとを含む。本実施形態では、第１面６２ａ及び第２面６２ｂは平面である。第１面６２ａ及び第２面６２ｂは、いずれも水平面に対して傾斜している。 The upper surface 62 of the connecting portion 60 of the present embodiment includes a first surface 62a and a second surface 62b that intersects the first surface 62a. In this embodiment, the first surface 62a and the second surface 62b are flat surfaces. Both the first surface 62a and the second surface 62b are inclined with respect to the horizontal plane.

第１面６２ａは、平面視において、筒状部材２０の中心Ｏ（本実施形態では円筒状の筒状部材２０の中心Ｏ）と上面６２の重心Ｇ（上面６２を水平面に投影した時の図形の重心）とを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って、水平面に対して傾斜する（図９参照）。具体的には、第１面６２ａは、第１方向Ｄ１に沿って次第に低くなるように、水平面に対して傾斜する（図９参照）。言い換えれば、第１面６２ａの高さは、筒状部材２０の周方向に沿って変化する。また、第１面６２ａは、好ましくは、第１直線Ｌに沿う方向において、筒状部材２０の中心Ｏ側が低くなる。つまり、本実施形態では、第１面６２ａは、筒状部材２０の周方向に沿って高さが変化し、筒状部材２０の中心Ｏ側ほど高さが低くなる。また、本実施形態では、第１面６２ａは、第１方向Ｄ１における下流側ほど幅が広くなる（図７及び図９参照）。そのため、筒状部材２０の中心Ｏの側から第１面６２ａを水平方向に見た時に、第１面６２ａは、平面視において第１直線Ｌに直交する第２方向Ｄ２に沿って低くなるとともに、上下方向の幅が広くなる（図８及び図９参照）。 The first surface 62a is a figure when the center O of the cylindrical member 20 (center O of the cylindrical member 20 in this embodiment) and the center of gravity G of the upper surface 62 (the upper surface 62 is projected onto a horizontal plane) in a plan view. It is inclined with respect to the horizontal plane along the first direction D1 intersecting the first straight line L connecting the center of gravity of the above (see FIG. 9). Specifically, the first surface 62a is inclined with respect to the horizontal plane so as to gradually decrease along the first direction D1 (see FIG. 9). In other words, the height of the first surface 62a changes along the circumferential direction of the tubular member 20. Further, the first surface 62a is preferably lower on the center O side of the tubular member 20 in the direction along the first straight line L. That is, in the present embodiment, the height of the first surface 62a changes along the circumferential direction of the tubular member 20, and the height becomes lower toward the center O side of the tubular member 20. Further, in the present embodiment, the width of the first surface 62a becomes wider toward the downstream side in the first direction D1 (see FIGS. 7 and 9). Therefore, when the first surface 62a is viewed horizontally from the side of the center O of the tubular member 20, the first surface 62a becomes lower along the second direction D2 orthogonal to the first straight line L in a plan view. , The width in the vertical direction becomes wider (see FIGS. 8 and 9).

第１面６２ａは、好ましくは、第１方向Ｄ１に沿って、水平面に対し１０°以上８５°未満の角度で傾斜している。より好ましくは、第１面６２ａは、第１方向Ｄ１に沿って、水平面に対し４５°以上８５°未満の角度で傾斜している。 The first surface 62a is preferably inclined at an angle of 10 ° or more and less than 85 ° with respect to the horizontal plane along the first direction D1. More preferably, the first surface 62a is inclined at an angle of 45 ° or more and less than 85 ° with respect to the horizontal plane along the first direction D1.

第２面６２ｂは、第１直線Ｌに沿う方向において筒状部材２０の中心Ｏ側が低くなる。限定するものではないが、本実施形態では、第２面６２ｂの高さは、筒状部材２０の周方向に沿って変化しない。本実施形態では、第２面６２ｂは、下方側ほど幅が広くなる（図７参照）。 The second surface 62b is lower on the center O side of the tubular member 20 in the direction along the first straight line L. Although not limited, in the present embodiment, the height of the second surface 62b does not change along the circumferential direction of the tubular member 20. In the present embodiment, the width of the second surface 62b becomes wider toward the lower side (see FIG. 7).

第２面６２ｂは、好ましくは、水平面に対し１０°以上８５°未満の角度で傾斜している。より好ましくは、第２面６２ｂは、水平面に対し４５°以上８５°未満の角度で傾斜している。 The second surface 62b is preferably inclined at an angle of 10 ° or more and less than 85 ° with respect to the horizontal plane. More preferably, the second surface 62b is inclined at an angle of 45 ° or more and less than 85 ° with respect to the horizontal plane.

次に、一対の連結部６０の関係について説明する。 Next, the relationship between the pair of connecting portions 60 will be described.

本実施形態では、連結部６０は、筒状部材２０の中心Ｏを挟んで対向する位置に配置されている。そして、一対の連結部６０の第１面６２ａは、筒状部材２０の周方向において同一方向に傾斜している。具体的には、図９の例では、後方側に配置される連結部６０の第１面６２ａは、上面視において反時計方向に、次第に高さが低くなるように水平面に対して傾斜している。言い換えれば、第１面６２ａは、上面視における反時計方向に沿って下り勾配となっている。また、前方側に配置される連結部６０の第１面６２ａも、上面視において反時計方向に、次第に高さが低くなるように水平面に対して傾斜している。言い換えれば、第１面６２ａは、上面視における反時計方向に沿って下り勾配となっている。本実施形態では、一対の連結部６０は、筒状部材２０の中心Ｏに対して互いに回転対称の関係にある。 In the present embodiment, the connecting portion 60 is arranged at a position facing each other with the center O of the tubular member 20 interposed therebetween. The first surface 62a of the pair of connecting portions 60 is inclined in the same direction in the circumferential direction of the tubular member 20. Specifically, in the example of FIG. 9, the first surface 62a of the connecting portion 60 arranged on the rear side is inclined counterclockwise with respect to the horizontal plane so that the height gradually decreases in the top view. There is. In other words, the first surface 62a has a downward slope along the counterclockwise direction in the top view. Further, the first surface 62a of the connecting portion 60 arranged on the front side is also inclined with respect to the horizontal plane in the counterclockwise direction in the top view so that the height gradually decreases. In other words, the first surface 62a has a downward slope along the counterclockwise direction in the top view. In the present embodiment, the pair of connecting portions 60 are rotationally symmetric with respect to the center O of the tubular member 20.

次に、連結部６０の上面６２が、上述のような形状の第１面６２ａを含む理由について説明する。 Next, the reason why the upper surface 62 of the connecting portion 60 includes the first surface 62a having the above-mentioned shape will be described.

まず、比較のため、連結部６０の上面６２の全体が水平面である場合を想定する。この場合、筒状部材２０の内部を落下し、上面６２に当たった物品Ｃや、（物品Ｃが小袋に包装された物品でない場合には）物品Ｃの欠片等は、上面６２に引っ掛かる可能性がある。特に、物品Ｃの長さが比較的長い場合には、物品Ｃが対向する連結部６０の２つの上面６２にまたがって引っ掛かり、落下しないおそれがある。このような事態が発生した場合には、物品Ｃの一部が袋Ｂに落下供給されず、袋Ｂに目標量の物品Ｃが収容されない可能性がある。 First, for comparison, it is assumed that the entire upper surface 62 of the connecting portion 60 is a horizontal plane. In this case, the article C that falls inside the tubular member 20 and hits the upper surface 62, or a fragment of the article C (if the article C is not an article packaged in a pouch) may be caught on the upper surface 62. There is. In particular, when the length of the article C is relatively long, the article C may be caught over the two upper surfaces 62 of the connecting portion 60 facing each other and may not fall. When such a situation occurs, a part of the article C may not be dropped and supplied to the bag B, and the target amount of the article C may not be accommodated in the bag B.

これに対し、本実施形態の製袋包装機１００では、連結部６０の上面６２が、第１面６２ａを含んでいる。第１面６２ａは、筒状部材２０の周方向に沿って高さが変化する面であるため、第１面６２ａ上に落下してくる物品Ｃに対し、筒状部材２０の周方向の力を作用させることができる。さらに、本実施形態では、第１面６２ａは、その連結部６０が取り付けられている筒状部材２０の内周面側よりも筒状部材２０の中心側の高さが低くなる、水平面に対する傾斜面である。言い換えれば、第１面６２ａは、筒状部材２０の内周面側よりも筒状部材２０の中心側の高さが低くなる下り勾配となっている。さらに言い換えれば、第１面６２ａは、筒状部材２０の径方向に沿って、筒状部材２０の中心側の高さが次第に低くなる下り勾配となっている。そのため、本実施形態では、第１面６２ａは、第１面６２ａ上に落下してくる物品Ｃに対し、前述の第１直線Ｌに沿う方向において、筒状部材２０の中心Ｏ側に向かう力も作用させることができる。より詳しく説明する。 On the other hand, in the bag making / packaging machine 100 of the present embodiment, the upper surface 62 of the connecting portion 60 includes the first surface 62a. Since the first surface 62a is a surface whose height changes along the circumferential direction of the tubular member 20, the force in the circumferential direction of the tubular member 20 with respect to the article C falling on the first surface 62a. Can be made to act. Further, in the present embodiment, the first surface 62a is inclined with respect to a horizontal plane so that the height of the central side of the tubular member 20 is lower than that of the inner peripheral surface side of the tubular member 20 to which the connecting portion 60 is attached. It is a face. In other words, the first surface 62a has a downward slope in which the height on the center side of the tubular member 20 is lower than that on the inner peripheral surface side of the tubular member 20. Further, in other words, the first surface 62a has a downward slope in which the height on the center side of the tubular member 20 gradually decreases along the radial direction of the tubular member 20. Therefore, in the present embodiment, the first surface 62a also has a force toward the center O side of the tubular member 20 in the direction along the first straight line L described above with respect to the article C falling on the first surface 62a. Can act. I will explain in more detail.

一般に、面に対し物品が衝突する場合、物品には面の法線方向（面に垂直な方向）に力が作用する。 Generally, when an article collides with a surface, a force acts on the article in the normal direction of the surface (direction perpendicular to the surface).

そのため、仮に連結部６０の上面が水平面であるとすれば、連結部６０の上面に落下してくる物品Ｃには、鉛直上向きの力が作用することとなる。つまり、仮に連結部６０の上面が水平面であるとすれば、連結部６０の上面に落下してくる物品Ｃには、水平方向の力が作用しない、又はほとんど作用しない。そのため、水平面である連結部６０の上面に落下してくる物品Ｃは、水平方向には位置や姿勢が変化しない可能性があり、連結部６０の上面に引っ掛かりやすい。 Therefore, if the upper surface of the connecting portion 60 is a horizontal plane, a vertically upward force acts on the article C falling on the upper surface of the connecting portion 60. That is, if the upper surface of the connecting portion 60 is a horizontal plane, no horizontal force acts on the article C falling on the upper surface of the connecting portion 60, or almost no force acts on the article C. Therefore, the article C that falls on the upper surface of the connecting portion 60 that is a horizontal plane may not change its position or posture in the horizontal direction, and is likely to be caught on the upper surface of the connecting portion 60.

一方で、本実施形態の第１面６２ａは、筒状部材２０の周方向に沿って高さが変化する面である。そのため、第１面６２ａ上に落下した物品Ｃには筒状部材２０の周方向（水平方向）にも力が作用しやすい。また、本実施形態の第１面６２ａは、その連結部６０が取り付けられている筒状部材２０の内周面側よりも筒状部材２０の中心側の高さが低くなる、水平面に対する傾斜面であるため、平面視において、物品Ｃには筒状部材２０の中心Ｏに向かう向き（水平方向）にも力が作用しやすい。そのため、本実施形態の第１面６２ａは、物品Ｃを水平方向に移動させて、物品Ｃが連結部６０の第１面６２ａに引っ掛かりにくくすることができる。 On the other hand, the first surface 62a of the present embodiment is a surface whose height changes along the circumferential direction of the tubular member 20. Therefore, a force is likely to act on the article C that has fallen on the first surface 62a also in the circumferential direction (horizontal direction) of the tubular member 20. Further, the first surface 62a of the present embodiment is an inclined surface with respect to a horizontal plane in which the height of the central side of the tubular member 20 is lower than that of the inner peripheral surface side of the tubular member 20 to which the connecting portion 60 is attached. Therefore, in a plan view, a force is likely to act on the article C also in the direction (horizontal direction) toward the center O of the tubular member 20. Therefore, the first surface 62a of the present embodiment can move the article C in the horizontal direction so that the article C is less likely to be caught on the first surface 62a of the connecting portion 60.

なお、第２面６２ｂも、その連結部６０が取り付けられている筒状部材２０の内周面側よりも筒状部材２０の中心側の高さが低くなる、水平面に対する傾斜面であるため、第２面６２ｂが水平面である場合に比べれば、物品Ｃを連結部６０の第２面６２ｂに引っ掛かりにくくすることができる。 Since the second surface 62b is also an inclined surface with respect to the horizontal plane, the height of the central side of the tubular member 20 is lower than that of the inner peripheral surface side of the tubular member 20 to which the connecting portion 60 is attached. Compared with the case where the second surface 62b is a horizontal plane, the article C can be made less likely to be caught on the second surface 62b of the connecting portion 60.

ただし、連結部６０の上面６２が、その連結部６０が取り付けられている筒状部材２０の内周面側よりも筒状部材２０の中心側の高さが低くなる第２面６２ｂだけしか有さないとすれば（第１面６２ａを有さないとすれば）、物品Ｃが比較的長さの長い物品である場合には、物品Ｃが一対の連結部６０の上面６２（第２面６２ｂ）上に同時に落下した場合には、連結部６０の上面６２（第２面６２ｂ）が物品Ｃに与える水平方向の力は互いに打ち消しあう。そのため、物品Ｃが連結部６０の上面６２（第２面６２ｂ）に引っ掛かるおそれがある。しかし、本製袋包装機１００では、連結部６０の上面６２が筒状部材２０の周方向に沿って高さが変化する第１面６２ａを有し、さらに、第１面６２ａは、筒状部材２０の周方向において同一方向に傾斜しているため、連結部６０の第１面６２ａ上に物品Ｃが落下した場合には、物品Ｃには、平面視において回転する力が作用する。その結果、連結部６０に物品Ｃが引っ掛かる不具合の発生が特に抑制される。 However, the upper surface 62 of the connecting portion 60 has only the second surface 62b whose height on the center side of the tubular member 20 is lower than that on the inner peripheral surface side of the tubular member 20 to which the connecting portion 60 is attached. If not (assuming it does not have the first surface 62a), if the article C is a relatively long article, the article C is the upper surface 62 (second surface) of the pair of connecting portions 60. 62b) When dropped onto the article C at the same time, the horizontal forces exerted by the upper surface 62 (second surface 62b) of the connecting portion 60 on the article C cancel each other out. Therefore, the article C may be caught on the upper surface 62 (second surface 62b) of the connecting portion 60. However, in the present bag making and packaging machine 100, the upper surface 62 of the connecting portion 60 has a first surface 62a whose height changes along the circumferential direction of the tubular member 20, and the first surface 62a is tubular. Since the member 20 is inclined in the same direction in the circumferential direction, when the article C falls on the first surface 62a of the connecting portion 60, a rotating force acts on the article C in a plan view. As a result, the occurrence of a problem that the article C is caught in the connecting portion 60 is particularly suppressed.

（２－２－６）横シール機構
横シール機構８０は、成形部１０、プルダウンベルト機構３０、縦シール機構４０及びゲート機構５０の下方に配置されている（図２参照）。横シール機構８０は、ヒータを内蔵する一対のシールジョー８２を含む機構である（図２参照）。 (2-2-6) Horizontal Seal Mechanism The horizontal seal mechanism 80 is arranged below the molded portion 10, the pull-down belt mechanism 30, the vertical seal mechanism 40, and the gate mechanism 50 (see FIG. 2). The lateral seal mechanism 80 is a mechanism including a pair of seal jaws 82 having a built-in heater (see FIG. 2).

一対のシールジョー８２は、限定するものではないが、図示されないモータにより駆動され、例えば、互いに対称な軌跡を描きながら略Ｄ字状に旋回する。このような旋回移動の駆動機構としては、例えば特開平１０－５３２０６号公報に開示されているような機構が用いられる。略Ｄ字状に旋回する一対のシールジョー８２は、互いに押しつけ合う状態で筒状フィルムＦｔを挟持し、袋Ｂの上下の端部となる筒状フィルムＦｔの一部分に圧力および熱を加えてシールを施す。一対のシールジョー８２は、縦シール機構４０により縦シールされた筒状フィルムＦｔを、筒状フィルムＦｔの搬送方向に交差する方向に横シールする。言い換えれば、横シール機構８０の一対のシールジョー８２は、筒状フィルムＦｔを、上下方向に交差する横方向に横シールする。特に本実施形態では、一対のシールジョー８２は、縦シール機構４０により縦シールされた筒状フィルムＦｔを、筒状フィルムＦｔの搬送方向に直交する方向に横シールする。また、シールジョー８２の片方の内部には、図示しないカッターが内蔵されている。カッターは、シールジョー８２による横シール部分の高さ方向の中心位置において、袋Ｂと後続の筒状フィルムＦｔとを切り離す。 The pair of seal jaws 82 are, but are not limited to, driven by a motor (not shown) and, for example, rotate in a substantially D shape while drawing symmetrical trajectories. As the driving mechanism for such turning movement, for example, a mechanism disclosed in Japanese Patent Application Laid-Open No. 10-53206 is used. A pair of seal jaws 82 that swivel in a substantially D shape hold the tubular film Ft in a state of being pressed against each other, and apply pressure and heat to a part of the tubular film Ft that is the upper and lower ends of the bag B to seal. To give. The pair of seal jaws 82 laterally seal the tubular film Ft vertically sealed by the vertical sealing mechanism 40 in a direction intersecting the conveying direction of the tubular film Ft. In other words, the pair of seal jaws 82 of the lateral sealing mechanism 80 laterally seal the tubular film Ft in the lateral direction intersecting in the vertical direction. In particular, in the present embodiment, the pair of seal jaws 82 laterally seal the tubular film Ft vertically sealed by the vertical sealing mechanism 40 in a direction orthogonal to the transport direction of the tubular film Ft. Further, a cutter (not shown) is built in one of the seal jaws 82. The cutter separates the bag B from the subsequent tubular film Ft at the center position in the height direction of the lateral seal portion by the seal jaw 82.

（３）製袋包装機の動作
以下に、コントローラ９０により制御される製袋包装機１００の動作について概説する。 (3) Operation of the bag-making / packaging machine The operation of the bag-making / packaging machine 100 controlled by the controller 90 will be outlined below.

製袋包装機１００では、プルダウンベルト機構３０が駆動されると、シート状のフィルムＦがフィルム供給ユニット１００ｂのフィルムロールから繰り出され、成形部１０に送られる。成形部１０では、シート状のフィルムＦは、フォーマ１２と筒状部材２０との隙間を通り抜ける間に筒状部材２０の外表面に巻き付けられ、筒状フィルムＦｔとなる。筒状フィルムＦｔは、プルダウンベルト機構３０により、筒状部材２０の外表面に沿って下方へと搬送される。シート状のフィルムＦが筒状部材２０に巻き付けられると、その横方向の両縁部が縦方向に重ね合わせられた状態となる。縦シール機構４０では、筒状フィルムＦｔの重ね合わせ部分が、縦方向に熱シールされる。その後、筒状フィルムＦｔは、筒状部材２０を抜けて横シール機構８０へと降りていく。 In the bag making / packaging machine 100, when the pull-down belt mechanism 30 is driven, the sheet-shaped film F is unwound from the film roll of the film supply unit 100b and sent to the molding unit 10. In the molding portion 10, the sheet-shaped film F is wound around the outer surface of the tubular member 20 while passing through the gap between the former 12 and the tubular member 20, and becomes the tubular film Ft. The tubular film Ft is conveyed downward along the outer surface of the tubular member 20 by the pull-down belt mechanism 30. When the sheet-shaped film F is wound around the tubular member 20, both lateral edges thereof are in a state of being overlapped in the vertical direction. In the vertical sealing mechanism 40, the overlapped portion of the tubular film Ft is heat-sealed in the vertical direction. After that, the tubular film Ft passes through the tubular member 20 and descends to the lateral sealing mechanism 80.

この際、組合せ計量器２から筒状部材２０を通って落下し、ゲート機構５０により一旦貯留されていた物品Ｃが、適切なタイミングで筒状フィルムＦｔの底部に対して供給される。具体的には、コントローラ９０は、適切なタイミングで、アーム駆動機構５６の動作を制御して、アーム５４をゲート部材閉鎖位置からゲート部材開放位置に移動させ、ゲート部材５２を第２位置から第１位置へと移動させ、ゲート機構５０を、ゲート部材５２を閉じた状態から、ゲート部材５２を開いた状態に変化させる。その結果、ゲート機構５０により一旦貯留されていた物品Ｃが、筒状フィルムＦｔの底部に対して供給される。 At this time, the article C that has fallen from the combination measuring instrument 2 through the tubular member 20 and has been temporarily stored by the gate mechanism 50 is supplied to the bottom of the tubular film Ft at an appropriate timing. Specifically, the controller 90 controls the operation of the arm drive mechanism 56 at an appropriate timing to move the arm 54 from the gate member closed position to the gate member open position, and moves the gate member 52 from the second position to the second position. It is moved to one position, and the gate mechanism 50 is changed from the state where the gate member 52 is closed to the state where the gate member 52 is opened. As a result, the article C once stored by the gate mechanism 50 is supplied to the bottom of the tubular film Ft.

なお、この後、コントローラ９０は、適切なタイミングで、アーム駆動機構５６の動作を制御して、アーム５４をゲート部材開放位置からゲート部材閉鎖位置に移動させ、ゲート部材５２を第１位置から第２位置へと移動させ、ゲート機構５０を、ゲート部材５２を開いた状態から、ゲート部材５２を閉じた状態に変化させ、ゲート機構５０に組合せ計量器２から筒状部材２０を通って落下する物品Ｃを受け取らせる。ゲート機構５０に落下してきた物品Ｃは、一対のゲート部材５２により受け取られ、貯留される。ゲート機構５０に貯留された物品Ｃは、次の袋Ｂが製袋される際に、上記のように、所定のタイミングで筒状フィルムＦｔの底部に対して供給される。 After that, the controller 90 controls the operation of the arm drive mechanism 56 at an appropriate timing to move the arm 54 from the gate member open position to the gate member closed position, and moves the gate member 52 from the first position to the first position. It is moved to two positions, the gate mechanism 50 is changed from the state where the gate member 52 is open to the state where the gate member 52 is closed, and it is combined with the gate mechanism 50 and falls from the measuring instrument 2 through the tubular member 20. Receive article C. The article C that has fallen into the gate mechanism 50 is received and stored by the pair of gate members 52. The article C stored in the gate mechanism 50 is supplied to the bottom of the tubular film Ft at a predetermined timing as described above when the next bag B is manufactured.

物品Ｃの入った袋Ｂの製造についての説明に戻る。横シール機構８０は、筒状フィルムＦｔ内にゲート機構５０が落下させた物品Ｃが存在する状態で、筒状フィルムＦｔを一対のシールジョー８２で横方向に熱シールし、先行する袋Ｂの上シール部分と、後続の袋Ｂの下シール部分とを同時に形成する。この時、一対のシールジョー８２の一方に内蔵されているカッター（図示省略）により、先行する袋Ｂと後続の袋Ｂ（筒状フィルムＦｔ）とが切り離される。 Returning to the description of the manufacture of the bag B containing the article C. In the horizontal sealing mechanism 80, the tubular film Ft is heat-sealed laterally with a pair of seal jaws 82 in a state where the article C dropped by the gate mechanism 50 is present in the tubular film Ft, and the preceding bag B The upper seal portion and the lower seal portion of the subsequent bag B are formed at the same time. At this time, the preceding bag B and the succeeding bag B (cylindrical film Ft) are separated from each other by a cutter (not shown) built in one of the pair of seal jaws 82.

（４）製袋包装機の特徴
（４－１）
本実施形態の製袋包装機１００は、成形部１０と、筒状部材２０と、揺動部材の一例としてのゲート部材５２と、連結部６０と、横シール機構８０と、を備える。成形部１０は、シート状のフィルムＦを筒状に成形する。筒状部材２０は、少なくとも部分的に成形部１０の下方に配置され、内部を物品Ｃが落下搬送される。ゲート部材５２は、筒状部材２０の下端部に配置されている。連結部６０は、筒状部材２０の内部側に張り出すように配置され、ゲート部材５２を筒状部材２０に対して揺動可能に連結する。横シール機構８０は、ゲート部材５２の下方に配置され、筒状に成形されたフィルムＦｔを上下方向に交差する横方向にシールする。連結部６０は、上面６２を有する。上面６２は、第１面６２ａを含む。第１面６２ａは、平面視において、筒状部材２０の中心Ｏと上面６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って、水平面に対して傾斜する。 (4) Features of bag making and packaging machine (4-1)
The bag-making / packaging machine 100 of the present embodiment includes a molding portion 10, a tubular member 20, a gate member 52 as an example of a swing member, a connecting portion 60, and a horizontal sealing mechanism 80. The molding unit 10 forms the sheet-shaped film F into a cylindrical shape. The tubular member 20 is at least partially arranged below the molding portion 10, and the article C is dropped and conveyed inside. The gate member 52 is arranged at the lower end of the tubular member 20. The connecting portion 60 is arranged so as to project toward the inside of the tubular member 20, and connects the gate member 52 to the tubular member 20 so as to be swingable. The lateral sealing mechanism 80 is arranged below the gate member 52, and seals the tubular film Ft in the lateral direction intersecting in the vertical direction. The connecting portion 60 has an upper surface 62. The upper surface 62 includes the first surface 62a. The first surface 62a is inclined with respect to the horizontal plane along the first direction D1 intersecting the first straight line L connecting the center O of the tubular member 20 and the center of gravity G of the upper surface 62 in a plan view.

本実施形態の製袋包装機１００では、平面視において、筒状部材２０を落下してきて連結部６０の第１面６２ａに接触した物品Ｃに回転力が作用しやすい。そのため、物品Ｃが連結部６０に引っ掛かりにくく、物品Ｃが袋Ｂ内に供給されない不具合の発生が抑制されやすい。 In the bag-making and packaging machine 100 of the present embodiment, in a plan view, a rotational force tends to act on the article C that has dropped the tubular member 20 and has come into contact with the first surface 62a of the connecting portion 60. Therefore, it is difficult for the article C to get caught in the connecting portion 60, and it is easy to suppress the occurrence of a problem that the article C is not supplied into the bag B.

（４－２）
本実施形態の製袋包装機１００では、筒状部材２０の中心Ｏ側から第１面６２ａを水平方向に見た時に、第１面６２ａは、平面視において第１直線Ｌに直交する第２方向Ｄ２に沿って低くなるとともに、上下方向の幅が広くなる。 (4-2)
In the bag making / packaging machine 100 of the present embodiment, when the first surface 62a is viewed horizontally from the center O side of the tubular member 20, the first surface 62a is a second surface orthogonal to the first straight line L in a plan view. As it becomes lower along the direction D2, the width in the vertical direction becomes wider.

本実施形態の製袋包装機１００では、連結部６０の第１面６２ａの上部側の幅が小さく形成されているため、物品Ｃは第１面６２ａの上部に引っ掛かりにくく、物品Ｃが袋Ｂ内に供給されない不具合の発生が抑制されやすい。 In the bag making / packaging machine 100 of the present embodiment, since the width of the upper side of the first surface 62a of the connecting portion 60 is formed to be small, the article C is less likely to be caught on the upper part of the first surface 62a, and the article C is the bag B. It is easy to suppress the occurrence of problems that are not supplied inside.

上記の実施形態や、以下に説明する変形例は、本発明の具体例であって、本発明の技術的範囲を限定するものではない。本発明の趣旨及び範囲から逸脱することなく、形態や詳細の多様な変更が可能なことが理解されるであろう。 (5) Modifications The above embodiments and the modifications described below are specific examples of the present invention and do not limit the technical scope of the present invention. It will be appreciated that various modifications of form and detail are possible without departing from the spirit and scope of the invention.

以下に上記実施形態の変形例について説明する。なお、以下の変形例のそれぞれは、矛盾の無い範囲で、他の各変形例の一部又は全部の特徴と適宜組み合わされてもよい。 A modified example of the above embodiment will be described below. In addition, each of the following modified examples may be appropriately combined with a part or all of the features of each of the other modified examples as long as there is no contradiction.

（５－１）変形例Ａ
上記実施形態では、連結部６０の上面６２は、第１面６２ａと第２面６２ｂとを含む。ただし、これに限定されるものではなく、後述する変形例Ｂのように、平面視において、連結部１６０，２６０の上面１６２，２６２は、筒状部材２０の中心Ｏと上面１６２，２６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って水平面に対して傾斜する第１面１６２ａ，２６２ａだけを有してもよい。また、連結部の上面は、筒状部材２０の中心Ｏと連結部の上面の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って水平面に対して傾斜する第１面を含む、互いに交差する３つ以上の面を含んでいてもよい。 (5-1) Modification A
In the above embodiment, the upper surface 62 of the connecting portion 60 includes a first surface 62a and a second surface 62b. However, the present invention is not limited to this, and as in the modified example B described later, in a plan view, the upper surfaces 162 and 262 of the connecting portions 160 and 260 are the centers of gravity of the center O of the tubular member 20 and the upper surfaces 162 and 262. It may have only first surfaces 162a, 262a that are inclined with respect to the horizontal plane along the first direction D1 that intersects the first straight line L connecting G. Further, the upper surface of the connecting portion is a first surface inclined with respect to the horizontal plane along the first direction D1 intersecting the first straight line L connecting the center O of the tubular member 20 and the center of gravity G of the upper surface of the connecting portion. It may include three or more faces that intersect each other, including.

（５－２）変形例Ｂ
上記実施形態では、連結部６０の上面６２の第１面６２ａは、筒状部材２０の中心Ｏと上面６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って水平面に対して傾斜するとともに、第１直線Ｌに沿う方向において筒状部材２０の中心Ｏ側が低くなっている。 (5-2) Modification B
In the above embodiment, the first surface 62a of the upper surface 62 of the connecting portion 60 is in a horizontal plane along the first direction D1 intersecting the first straight line L connecting the center O of the tubular member 20 and the center of gravity G of the upper surface 62. On the other hand, it is inclined and the center O side of the tubular member 20 is lowered in the direction along the first straight line L.

しかし、これに限定されるものではなく、図１０のように、連結部１６０の上面１６２は、筒状部材２０の中心Ｏと上面１６２の重心Ｇとを結ぶ第１直線Ｌに交差する（ここでは直交する）第１方向Ｄ１に沿って水平面に対して傾斜し、第１直線Ｌに沿う方向においては高さが変化しない第１面１６２ａを有していてもよい。なお、連結部１６０の上面１６２が、上記実施形態のように互いに交差する複数の面を含む場合であっても、各面は、第１直線Ｌに沿う方向においては高さが変化していなくてもよい。 However, the present invention is not limited to this, and as shown in FIG. 10, the upper surface 162 of the connecting portion 160 intersects the first straight line L connecting the center O of the tubular member 20 and the center of gravity G of the upper surface 162 (here). It may have a first surface 162a that is inclined with respect to the horizontal plane along the first direction D1 and whose height does not change in the direction along the first straight line L. Even when the upper surface 162 of the connecting portion 160 includes a plurality of surfaces that intersect each other as in the above embodiment, the height of each surface does not change in the direction along the first straight line L. You may.

ただし、物品Ｃを連結部の上面に引っ掛かりにくくするという観点からは、上記実施形態のように、連結部６０の上面６２は、筒状部材２０の中心Ｏと上面６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って水平面に対して傾斜するとともに、第１直線Ｌに沿う方向において筒状部材２０の中心Ｏ側が低くなっていることが好ましい。例えば、図１１のように、連結部２６０の上面２６２が第１面２６２ａのみを有する場合、連結部２６０の上面２６２の第１面２６２ａは、筒状部材２０の中心Ｏと上面２６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向Ｄ１に沿って水平面に対して傾斜するとともに、第１直線Ｌに沿う方向において筒状部材２０の中心Ｏ側が低くなっていることが好ましい。 However, from the viewpoint of making it difficult for the article C to be caught on the upper surface of the connecting portion, the upper surface 62 of the connecting portion 60 connects the center O of the tubular member 20 and the center of gravity G of the upper surface 62, as in the above embodiment. It is preferable that the cylindrical member 20 is inclined with respect to the horizontal plane along the first direction D1 intersecting the first straight line L, and the center O side of the tubular member 20 is lower in the direction along the first straight line L. For example, as shown in FIG. 11, when the upper surface 262 of the connecting portion 260 has only the first surface 262a, the first surface 262a of the upper surface 262 of the connecting portion 260 has the center O of the tubular member 20 and the center of gravity G of the upper surface 262. It is preferable that the cylindrical member 20 is inclined with respect to the horizontal plane along the first direction D1 intersecting the first straight line L and the center O side of the tubular member 20 is lower in the direction along the first straight line L.

なお、図１０、図１１では、第１面１６２ａ，２６２ａの場所が分かりやすいよう、第１面１６２ａ，２６２ａにハッチングを付している。 In FIGS. 10 and 11, the first surfaces 162a and 262a are hatched so that the locations of the first surfaces 162a and 262a can be easily understood.

（５－３）変形例Ｃ
上記実施形態では、連結部６０の上面６２の第１面６２ａは平面である。ただし、これに限定されるわけではない。例えば、図１２のように、連結部３６０の上面３６２の第１面３６２ａは、筒状部材２０の中心Ｏと上面６２の重心Ｇとを結ぶ第１直線Ｌに交差する第１方向に沿って水平面に対して傾斜するとともに、第１直線Ｌに沿う方向において筒状部材２０の中心Ｏ側が低くなっている曲面であってもよい。なお、曲面では、傾きの方向が場所により変化するため、図１２中には第１方向を描画していない。また、図１２では、第１面３６２ａの場所が分かりやすいよう、第１面３６２ａにハッチングを付している。 (5-3) Modification C
In the above embodiment, the first surface 62a of the upper surface 62 of the connecting portion 60 is a flat surface. However, it is not limited to this. For example, as shown in FIG. 12, the first surface 362a of the upper surface 362 of the connecting portion 360 is along the first direction intersecting the first straight line L connecting the center O of the tubular member 20 and the center of gravity G of the upper surface 62. It may be a curved surface that is inclined with respect to the horizontal plane and the center O side of the tubular member 20 is lowered in the direction along the first straight line L. Since the direction of inclination of the curved surface changes depending on the location, the first direction is not drawn in FIG. Further, in FIG. 12, hatching is attached to the first surface 362a so that the location of the first surface 362a can be easily understood.

ただし、第１面３６２ａが曲面である場合、第１面３６２ａは、筒状部材２０の周方向に沿って、第１面３６２ａが（傾斜の角度は変わっても）同一方向に傾斜していることが好ましい。例えば、図１２の例であれば、連結部３６０の上面３６２の第１面３６２ａは、平面視における筒状部材２０の中心Ｏに対する反時計方向に沿って、高さが次第に低くなることが好ましい。 However, when the first surface 362a is a curved surface, the first surface 362a is inclined in the same direction (even if the angle of inclination changes) along the circumferential direction of the tubular member 20. Is preferable. For example, in the case of FIG. 12, it is preferable that the height of the first surface 362a of the upper surface 362 of the connecting portion 360 gradually decreases along the counterclockwise direction with respect to the center O of the tubular member 20 in a plan view. ..

なお、連結部の製造のしやすさや、連結部に物品Ｃが引っ掛かりにくくするという目的からは、連結部の上面の第１面は、例えば上記実施形態の第１面６２ａのように平面であることが好ましい。 The first surface of the upper surface of the connecting portion is a flat surface, for example, as in the first surface 62a of the above embodiment, for the purpose of facilitating the manufacture of the connecting portion and preventing the article C from being caught in the connecting portion. Is preferable.

（５－４）変形例Ｄ
上記実施形態では、連結部６０の上面６２の第１面６２ａは、第１方向における下流側ほど幅が広くなっている。そして、筒状部材２０の中心側から第１面６２ａを水平方向に見た時に、第１面６２ａは、平面視において第１直線Ｌに直交する第２方向Ｄ２に沿って低くなるとともに、上下方向の幅が広くなっている。 (5-4) Modification D
In the above embodiment, the first surface 62a of the upper surface 62 of the connecting portion 60 has a wider width toward the downstream side in the first direction. Then, when the first surface 62a is viewed horizontally from the center side of the tubular member 20, the first surface 62a becomes lower along the second direction D2 orthogonal to the first straight line L in a plan view, and is up and down. The width of the direction is wide.

ただし、これに限定されるものではない。例えば、図１１の連結部２６０ように、筒状部材２０の中心側から連結部２６０の上面２６２の第１面２６２ａを水平方向に見た時に、第１面２６２ａは、平面視において第１直線Ｌに直交する第２方向Ｄ２に沿って低くなるが、上下方向の幅は一定であってもよい。 However, the present invention is not limited to this. For example, as in the connecting portion 260 of FIG. 11, when the first surface 262a of the upper surface 262 of the connecting portion 260 is viewed horizontally from the center side of the tubular member 20, the first surface 262a is the first straight line in a plan view. It becomes lower along the second direction D2 orthogonal to L, but the width in the vertical direction may be constant.

（５－５）変形例Ｅ
上記実施形態では、ゲート機構５０のゲート部材５２が２つである場合を例に説明したが、ゲート部材５２の数は２つ限定されない。例えば、ゲート機構は、単一のゲート部材で物品Ｃの移動経路を閉鎖するものであってもよいし、３つ以上のゲート部材で物品Ｃの移動経路を閉鎖するものであってもよい。 (5-5) Modification E
In the above embodiment, the case where the gate mechanism 50 has two gate members 52 has been described as an example, but the number of the gate members 52 is not limited to two. For example, in the gate mechanism, a single gate member may close the movement path of the article C, or three or more gate members may close the movement path of the article C.

この場合にも、連結部６０の上面６２が上述したような形状を有することで、物品Ｃが連結部６０に引っ掛かる不具合を抑制できる。なお、３つ以上のゲート部材を設ける場合には、複数の連結部６０の第１面６２ａに当たった物品Ｃに平面視において物品Ｃに回転する力を与えるように、複数の連結部の第１面は、周方向において同一方向に傾斜していることが好ましい。 Also in this case, since the upper surface 62 of the connecting portion 60 has the shape as described above, it is possible to suppress the problem that the article C is caught in the connecting portion 60. When three or more gate members are provided, the first of the plurality of connecting portions is provided so as to give a rotating force to the article C in a plan view to the article C hitting the first surface 62a of the plurality of connecting portions 60. It is preferable that one surface is inclined in the same direction in the circumferential direction.

（５－６）変形例Ｆ
上記実施形態では、揺動部材が、筒状部材内を落下してくる物品Ｃを受け止めるゲート部材５２である場合を例に説明した。つまり、上記実施形態では、揺動部材が、平面視において筒状部材２０の外側に入り込むように揺動する場合を例に説明した。 (5-6) Modification F
In the above embodiment, the case where the rocking member is the gate member 52 that receives the article C falling in the tubular member has been described as an example. That is, in the above embodiment, the case where the swinging member swings so as to enter the outside of the tubular member 20 in a plan view has been described as an example.

ただし、これに限定されるものではなく、本発明の揺動部材は、図１３に示されるような、成形部１０により筒状に成形されて筒状部材２０の外面に沿って搬送されてくる筒状フィルムＦｔを押し広げるスプレッダ４５２であってもよい。つまり、本発明の揺動部材は、平面視において筒状部材２０の外側に広がるように揺動する部材であってもよい。また、製袋包装機１００は、ゲート部材５２に加えて、スプレッダ４５２を有していてもよい。 However, the present invention is not limited to this, and the rocking member of the present invention is formed into a cylindrical shape by the forming portion 10 and is conveyed along the outer surface of the tubular member 20 as shown in FIG. It may be a spreader 452 that spreads the tubular film Ft. That is, the swinging member of the present invention may be a member that swings so as to spread outside the tubular member 20 in a plan view. Further, the bag making / packaging machine 100 may have a spreader 452 in addition to the gate member 52.

この場合にも、筒状部材２０の内部側に張り出すように配置され、筒状部材２０とスプレッダ４５２とを連結する連結部４６０の上面４６２が、図６から図９を用いて説明した上面６２と同様の第１面６２ａを有する場合、上記実施形態と同様の効果が得られる。また、筒状部材２０とスプレッダ４５２とを連結する連結部４６０の上面４６２は、図１０～図１２を用いて説明したような第１面１６２ａ，２６２ａ，３６２ａと同様の形状を有するものであってもよい。 Also in this case, the upper surface 462 of the connecting portion 460, which is arranged so as to project to the inner side of the tubular member 20 and connects the tubular member 20 and the spreader 452, is the upper surface described with reference to FIGS. 6 to 9. When the first surface 62a similar to 62 is provided, the same effect as that of the above embodiment can be obtained. Further, the upper surface 462 of the connecting portion 460 that connects the tubular member 20 and the spreader 452 has the same shape as the first surface 162a, 262a, 362a as described with reference to FIGS. 10 to 12. You may.

なお、スプレッダ４５２は、例えば特許文献１（特開２０１３－３５６０１号公報）に記載された四角成形用スプレッダ４１やシール用スプレッダ４７と同様の部材であり、筒状フィルムＦｔの外側からプッシャ（図示せず）に押されることで図１３（ａ）のような閉じた状態から、図１３（ｂ）のような開いた状態に変化する。スプレッダ４５２は、袋Ｂを所望の形状に成形すること等を目的として、筒状フィルムＦｔを内側から押し広げる部材である。 The spreader 452 is, for example, a member similar to the square forming spreader 41 and the sealing spreader 47 described in Patent Document 1 (Japanese Unexamined Patent Publication No. 2013-35601), and is a pusher from the outside of the tubular film Ft (FIG. By being pushed by (not shown), the closed state as shown in FIG. 13 (a) changes to the open state as shown in FIG. 13 (b). The spreader 452 is a member that spreads the tubular film Ft from the inside for the purpose of forming the bag B into a desired shape and the like.

なお、スプレッダ４５２を利用する場合、製袋包装機１００に、上記実施形態で説明した以外の袋Ｂの成形用の機構が設けられる場合がある。しかし、スプレッダ４５２の機能や、スプレッダ４５２を利用した袋Ｂの成形については広く知られていること（例えば特許文献１（特開２０１３－０３５６０１号公報）参照）、本発明は、スプレッダ４５２の構造・機能や、スプレッダ４５２を利用した袋Ｂの成形方法よりも、筒状部材２０とスプレッダ４５２とを連結する連結部４６０の形状に特徴があることから、ここではスプレッダ４５２の機能や、スプレッダ４５２を利用した袋Ｂの成形のための機構についての詳細な説明は省略する。 When the spreader 452 is used, the bag making / packaging machine 100 may be provided with a mechanism for forming the bag B other than that described in the above embodiment. However, the function of the spreader 452 and the molding of the bag B using the spreader 452 are widely known (see, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2013-305601)), and the present invention has the structure of the spreader 452. -Since the function and the shape of the connecting portion 460 that connects the tubular member 20 and the spreader 452 are more characteristic than the method of forming the bag B using the spreader 452, here, the function of the spreader 452 and the spreader 452 are characterized. A detailed description of the mechanism for forming the bag B using the above will be omitted.

（５－７）変形例Ｇ
上記実施形態では、第１面６２ａは、上面視において反時計方向に、次第に高さが低くなるように水平面に対して傾斜している。言い換えれば、第１面６２ａは、上面視における反時計方向に沿って下り勾配となっている。ただし、傾斜の方向は、上記実施形態に記載の内容に限定されない。 (5-7) Modification G
In the above embodiment, the first surface 62a is inclined counterclockwise with respect to the horizontal plane so that the height gradually decreases in the top view. In other words, the first surface 62a has a downward slope along the counterclockwise direction in the top view. However, the direction of inclination is not limited to the content described in the above embodiment.

例えば、第１面６２ａは、上面視において時計方向に、次第に高さが低くなるように水平面に対して傾斜していてもよい。言い換えれば、第１面６２ａは、上面視における時計方向に沿って下り勾配となっていてもよい。 For example, the first surface 62a may be inclined with respect to the horizontal plane in the clockwise direction in the top view so that the height gradually decreases. In other words, the first surface 62a may have a downward slope along the clockwise direction in the top view.

本発明は、内部を物品が落下搬送される筒状部材の下端部に揺動部材が配置される製袋包装機に広く適用でき有用である。 INDUSTRIAL APPLICABILITY The present invention is useful because it can be widely applied to a bag-making and packaging machine in which a swing member is arranged at the lower end of a tubular member to which an article is dropped and conveyed inside.
