Description

本発明は、自動製袋機の底貼り工程における袋筒体の底開き装置に関し、特に、最内層袋にプラスチック素材を用い、外層袋に紙素材を用いた多層底貼り袋の製作工程における多層袋筒体の底開き装置に関する。   The present invention relates to a bottom opening apparatus of a bag cylinder in a bottom attaching process of an automatic bag making machine, and in particular, a multilayer material in a manufacturing process of a multilayer bottom attaching bag using a plastic material for an innermost layer bag and a paper material for an outer layer bag. The present invention relates to a bottom opening device of a bag cylinder.

主に製品の輸送や貯蔵などを目的として使用される多層袋(重包装袋)として、最内層(製品充填部分)にポリエチレン等のプラスチック素材からなる袋を用い、外層(1層〜3層)にクラフト紙等の紙素材を用いた袋であって、底の部分を方形状に貼り合せて形成する袋が常用されている。   Outer layer (1 to 3 layers) using a bag made of a plastic material such as polyethylene as the innermost layer (the product filled portion) as a multilayer bag (heavy packaging bag) mainly used for the purpose of transportation and storage of products A bag made of a paper material such as kraft paper is commonly used which is formed by laminating bottom portions in a square shape.

このように最内層にプラスチック素材からなる袋を用いる目的は、主に内容物に対して湿度の影響を遮断することによって防湿効果が得られることや、密閉効果が得られることによって異物混入の可能性を低減することができるところにある。また、底部を方形状(例えば六角形状)に貼り合わせた底貼り袋とするのは、製品充填時に自立し易いため作業性に優れ、製品充填後には荷姿が立方体になるので積載効率が良いところにある。   The purpose of using a bag made of a plastic material for the innermost layer in this way is that the moisture-proof effect can be obtained mainly by blocking the influence of humidity on the contents, and foreign matter can be mixed in by obtaining a sealing effect. It is in the place where it can reduce the In addition, it is easy to stand at the time of product filling because it is easy to stand at the time of product filling, and it is excellent in workability because the bottom part is pasted in a square shape (for example, hexagonal shape). It is in the place.

この種の多層底貼り袋を製作するには、先ず、ロール状の外層原紙とプラスチック筒体を引き出し、外層原紙によりプラスチック筒体を内装するとともに、外層原紙の胴貼部に糊付けして袋幅に成形することによって連続した多層筒体を形成し、所定長さに切断して各層間の底部及び口部に必要な箇所が開けるよう所定位置に接着剤を点付けして多層筒体を造った後にプラスチック筒体の底部をヒートシールして封着する(図8参照)。   In order to produce this type of multi-layered bottom attachment bag, first, the roll-like outer layer base paper and the plastic cylinder are pulled out, the plastic cylinder is embedded with the outer layer base paper, and the bag width of the outer layer base paper is glued Forming a continuous multi-layered cylinder by forming into a multi-layered cylinder by cutting into a predetermined length and spotting an adhesive at a predetermined position so as to open the necessary places in the bottom and the mouth between each layer After that, the bottom of the plastic cylinder is heat sealed and sealed (see FIG. 8).

次に、前記多層筒体の底部を開き、開いた底部分を所定の底幅が得られるよう方形状に整えて折り畳み、折り畳んだ各片の重合面に接着剤を点付けして貼着する。そして、必要に応じ底面に補強紙を貼る等して底貼りを完成させる(図9、図10参照)。   Next, open the bottom of the multilayer cylinder, arrange the open bottom portion in a square shape so as to obtain a predetermined bottom width, fold it, and place an adhesive on the polymerization surface of each folded piece and stick it . Then, reinforcing paper is attached to the bottom as needed to complete bottom attachment (see FIGS. 9 and 10).

上記底貼り工程において、多層筒体の底を開く時には筒体の底を2方向に開く必要があるが、プラスチック筒体の底部分はヒートシールされ袋状に封着されているため開くことが出来ないので、外層紙筒体の上側又は下側のいずれか一方側の内側面にシール済みプラスチック袋体を点糊貼着して、プラスチック袋体と外層紙筒体の一方側を一体とした状態で筒体底を開き底貼りをすることになる(図9,図10参照)。   In the bottom attaching step, when the bottom of the multilayer cylinder needs to be opened, it is necessary to open the bottom of the cylinder in two directions. However, the bottom of the plastic cylinder is heat sealed and sealed in a bag shape. Since it can not be done, a sealed plastic bag is attached to the inner side surface of either the upper side or the lower side of the outer layer paper cylinder, and one side of the plastic bag and the outer layer paper cylinder is integrated. In the state, the bottom of the cylinder is opened and the bottom is attached (see FIGS. 9 and 10).

従来の自動底貼り機で多く採用されている底開き装置について、図6及び図7を用いて説明すると、水平方向に配置された左右一対の回転軸50、50のそれぞれに回転アーム51、51の一方端を固定し、回転アーム51、51の他方端間にピン52、52で回動自在に軸支され水平状態を保って円運動する支持アーム53を連結し、該支持アーム53の下部に吸盤54を取り付けてなる吸着機構を、水平横方向に移送されてくる袋筒体の上側と下側とに対向して二組配設した構成からなる。
かかる構成からなる従来装置にあっては、吸盤54、54の動作は円運動となるので、上側吸盤54の最下降時で下側吸盤54の最上昇時に袋筒体の上下面をそれぞれ吸着し、下死点、上死点から先は上下吸盤54,54が袋筒体の底を開くよう動作する。そのため、袋筒体の進行に対して上下吸盤54,54が同調する範囲は上側吸盤54の最下降点で下側吸盤54の最上昇点の一点しかなく、吸着のための最適範囲は限られていて十分な吸着作用が得られていない。
The bottom opening device often adopted in the conventional automatic bottoming machine will be described with reference to FIGS. 6 and 7. The rotating arms 51, 51 are respectively provided on the pair of left and right rotary shafts 50, 50 arranged in the horizontal direction. And one end of the rotating arm 51, 51 is rotatably supported by the pins 52, 52 between the other ends of the rotating arms 51, 51, and supports the horizontally movable supporting arm 53 connected to the lower portion of the supporting arm 53; The suction mechanism having the suction cups 54 attached thereto is arranged in two sets facing the upper and lower sides of the bag cylinder transferred in the horizontal direction.
In the conventional apparatus having such a configuration, the motions of the suction cups 54, 54 are circular motions, and the upper and lower surfaces of the bag cylinder are respectively adsorbed when the lower suction cup 54 is lifted ascending at the highest descent of the upper sucker 54. From the bottom dead center and the top dead center, the upper and lower suction cups 54 and 54 operate to open the bottom of the cylinder. Therefore, the range in which the upper and lower suction cups 54 and 54 are synchronized with the movement of the bag cylinder is only the lowest point of the upper suction cup 54 and only one point of the highest rise point of the lower suction cup 54, and the optimum range for adsorption is limited. And sufficient adsorption effect is not obtained.

しかしながら、最内層袋材としてプラスチック材を使用した多層袋にあっては、内層プラスチック筒体をヒートシールする工程で外層紙材と内層プラスチック材とを共に加熱し圧着するため、内層プラスチック筒体と分離して開くべき外層紙筒体が内層プラスチック材とラミネートしたような状態で付着(内着)してしまい、この付着が底貼り機で多層筒体の底を開く時の障害になっている。前記従来底貼り機のように、吸着に使える時間が短く筒体相互の内着を引き剥がす程の吸着力を発揮できないと、結果として、底開き動作の途中で吸盤が筒体を離してしまい底開きが十分できないトラブルが頻発する。このため従来底貼り機を使用する場合、内層プラスチック筒体底のヒートシールが終わった多層筒体を一旦自動製袋ラインから外し、手作業で一袋ずつ外層紙材と内層プラスチック材とのヒートシール部の付着を剥がし、その後に、改めて底貼り機に掛けて底貼りをしなければならないという問題がある。   However, in the case of a multilayer bag using a plastic material as the innermost layer bag material, the outer layer paper material and the inner layer plastic material are both heated and crimped together in the step of heat sealing the inner layer plastic cylinder, The outer layer paper cylinder that should be opened separately is attached (internally attached) in a state of being laminated with the inner layer plastic material, and this adhesion is an obstacle when opening the bottom of the multilayer cylinder with the bottom sticking machine . As in the conventional bottom attachment machine, if the time available for adsorption is short and can not exert an adsorption power enough to pull off the inner sleeves of the cylinders, as a result, the sucker separates the cylinders in the middle of the bottom opening operation. Frequent problems occur that can not be fully opened. For this reason, when using a conventional bottom attachment machine, the multilayer cylinder whose heat seal at the inner plastic cylinder bottom has been finished is temporarily removed from the automatic bag-making line, and manually heats the outer layer paper material and the inner layer plastic material one bag at a time. There is a problem that it is necessary to peel off the adhesion of the sealing portion and then to put it on the bottom sticking machine again to paste the bottom.

本発明は、上記従来底貼り機による問題点に鑑みなされ、吸盤による筒体への吸着力を強化することによって、手作業に頼ることなく、確実な底開きを可能とした装置の提供を目的としたものである。   The present invention has been made in view of the problems caused by the above-described conventional bottom sticking machine, and aims to provide an apparatus capable of reliably opening the bottom without relying on manual work by strengthening the suction force to the cylinder by the suction cup. The

上記目的を達成するために、請求項1に記載の発明は、筒体底部を折りたたみ貼着して角底の底貼り袋を成形する自動製袋機において、水平横方向に送られて来る筒体の進行に同期して回転する左右一対のスプロケットを所定の軸間距離にて配設し、これにローラチェーンを巻掛してなる伝動機構と、前記ローラチェーンの走行に連動して循環運動する吸盤を備える吸着機構からなるユニット二組を、筒体底部を間にして上下に対向設置した袋筒体の底開き装置であって、前記吸着機構における上側吸盤の最下降点で下側吸盤の最上昇点にあっては、筒体の上下面を上下吸盤のそれぞれが吸着し、上側吸盤の上昇開始点で下側吸盤の下降開始点からは、筒体の上下面を上下吸盤のそれぞれが吸引して筒体底部を開くよう構成したことを特徴とするものである。   In order to achieve the above object, the invention according to claim 1 is an automatic bag making machine that folds and adheres the bottom of a cylinder to form a bottom-attached bag with a square bottom, and a cylinder that is fed in a horizontal direction. A transmission mechanism comprising a pair of left and right sprockets that rotate in synchronization with the movement of the body at a predetermined axial distance, and a roller chain wound around it, and a circulation motion linked to the travel of the roller chain A bottom opening device of a bag cylinder in which two sets of units comprising a suction mechanism including a suction cup are vertically opposed with the bottom portion of the cylinder interposed therebetween, the lower suction cup at the lowest point of the upper suction cup in the suction mechanism The top and bottom surfaces of the cylinder are adsorbed by the upper and lower suction cups, respectively, and the upper and lower surfaces of the upper and lower suction cups are attracted from the upper and lower suction cups, respectively. Is configured to open the bottom of the cylinder by suction. Is shall.

請求項2に記載の発明は、請求項1記載の構成において、循環運動する上下吸盤に対し、上下運動を制御するエアーシリンダー等の昇降機構をそれぞれ組み込んだ構成からなり、上下吸盤がローラチェーン走行に連動して水平移動する同調区間での十分な時間の中で、上下吸盤と筒体上下面とのそれぞれの吸着及び吸引動作のより強力且つ正確な実施を可能にして、動作シーケンスの自由度を大幅に拡げたことを特徴とするものである。   The invention according to claim 2 has a construction according to claim 1 in which a lifting mechanism such as an air cylinder for controlling the up and down movement is incorporated into the up and down suction cups moving in circulation. To allow more powerful and accurate implementation of the suction and suction operations of the upper and lower suction cups and the upper and lower surfaces of the cylinder within a sufficient time in the synchronized section moving horizontally in conjunction with the It is characterized in that the

請求項3に記載の発明は、請求項1及び請求項2に記載の構成に置いて、スプロケットとローラチェーンからなる伝動機構を、所定間隔を空け上下平行に二基配設したことを特徴とするものである。   The invention according to claim 3 is characterized in that, in the configuration according to claim 1 and claim 2, two transmission mechanisms consisting of a sprocket and a roller chain are provided in parallel in the vertical direction at predetermined intervals. It is

本発明は上記構成よりなり、請求項1に係る発明は、水平横方向に送られて来る筒体の進行に同調して回転する一対のスプロケットを、所定の軸間距離にて左右水平に配設したことにより、左右スプロケットの軸間ではローラチェーンの走行は水平となり、これに連動する吸盤の循環運動も水平移動(筒体面に対して平行移動)することになるため、その分、上下吸盤と筒体上下面との吸着に適した時間(区間)も長くなって、十分な吸着効果を得ることができる。   The present invention has the above-described configuration, and the invention according to claim 1 distributes a pair of sprockets, which rotate in synchronization with the progress of a cylinder sent in the horizontal direction, horizontally and horizontally at a predetermined axial distance. Since the roller chain travels horizontally between the shafts of the left and right sprockets and the circular movement of the suction cup linked to this is also moved horizontally (parallel movement with respect to the cylinder surface), the upper and lower suction cups The time (section) suitable for the adsorption between the cylinder and the upper and lower surfaces of the cylinder also becomes long, and a sufficient adsorption effect can be obtained.

請求項2に係る発明は、循環運動する上下吸盤に対し、その上下運動を制御するエアーシリンダー等の昇降機構を組み込んだことにより、昇降機構の昇降動作により吸盤の上下動が制御される。これによって、上下吸盤と筒体上下面との吸着及び吸引動作のより強力で正確な実施が可能となり、動作シーケンスの自由度を大幅に拡げることも可能とした。   According to the second aspect of the present invention, the vertical movement of the suction cup is controlled by the vertical movement of the vertical movement mechanism by incorporating a vertical movement mechanism such as an air cylinder for controlling the vertical movement of the vertical suction disk which circulates. As a result, the suction and suction operations between the upper and lower suction cups and the upper and lower surfaces of the cylinder can be performed more strongly and accurately, and the degree of freedom of the operation sequence can be greatly expanded.

以上の本発明の作用効果により、特に、最内層袋にプラスチック材を使用し、外層袋に紙材を使用した多層袋にあって、最内層のプラスチック材からなる袋筒体と外層の紙材からなる袋筒体との底開口附近で、ヒートシールによる内着が生じてしまった場合であっても、上下吸盤がローラチェーン走行に連動して水平移動する同調区間内での十分な時間(区間)の中で上下吸盤と多層筒体面との吸着ができ、これによって、確実且つ強力な吸着及び吸引力で袋筒体の底開きが実施できるため、従来装置のように手作業に頼ることなく袋筒体の連続した自動底開きが可能となった。     In the multi-layer bag using a plastic material for the innermost layer bag and using a paper material for the outer layer bag by the above-described effects of the present invention, in the multi-layered bag using the innermost layer plastic material Even if the inner seal by heat sealing occurs near the bottom opening with the bag cylinder consisting of the upper and lower suction cups, sufficient time in the synchronized section where the upper and lower suction cups move horizontally in conjunction with the roller chain travel ( The upper and lower suction cups and the multi-layer cylinder surface can be adsorbed within the section), which allows the bottom opening of the bag cylinder to be carried out with reliable and strong adsorption and suction power, so manual operation is required as in the conventional device. It became possible to open the bottom of the bag cylinder continuously.

Hereinafter, embodiments of the present invention will be described based on the drawings.
FIG. 1 is an explanatory front view showing an example of a bottom opening device of a bag cylinder, FIG. 2 is an explanatory plan view of the same device, and FIG. 3 is an explanatory view of the right side of the same device.
First, in a cylinder making machine (not shown), the roll-like outer layer base paper and the inner layer plastic cylinder are drawn out, and the plastic cylinder is internally fitted with the outer layer base paper, and is glued to the body-sticking portion of the outer layer base paper to form a bag width. To form a continuous multi-layered cylinder. Next, this continuous multilayer cylinder is cut into a predetermined length, and an adhesive is spotted at a predetermined position so as to open a necessary place in the bottom and the mouth between the respective layers (Fig. 8 to 10)).

本実施形態の底開き装置1による前記多層筒体Aの搬送経路について、図1及び図2に基づき説明すると、先ず、ローラコンベア2によって多層筒体Aの底部を前にして水平縦方向に間欠的に搬送する。このローラコンベア2は、平行に配置された左右のサイドフレーム3,3間に複数の駆動又は従動の回転ローラ4が所定間隔で回転可能に軸支されている。そして、搬送方向先端部には、多層筒体Aが停止する基準位置を決める固定ガイド板5がサイドフレーム3,3間に架設されている。また、この基準位置に載置された多層筒体Aを底開き機構部10へ水平方向に移送すための送り爪6は、スプロケット8a、8b、8cによって循環駆動されるローラチェーン7に等間隔に設置され、ローラコンベア2とチェーンカバー7上の多層筒体Aを横に押して移送できる高さに突設されている。
すなわち、多層筒体Aは、筒体底部をローラコンベア2で固定ガイド板5に寄せられた状態でローラチェーン7に押され、水平右方向に移送される。
The conveyance path of the multilayer cylinder A by the bottom opening device 1 of the present embodiment will be described based on FIGS. 1 and 2. First, the roller conveyor 2 intermittently cuts in the horizontal and vertical directions with the bottom of the multilayer cylinder A facing forward. Transport. In the roller conveyor 2, a plurality of driven or driven rotary rollers 4 are rotatably supported at predetermined intervals between left and right side frames 3 arranged in parallel. A fixed guide plate 5 for determining a reference position at which the multilayer cylinder A stops is bridged between the side frames 3 and 3 at the leading end in the transport direction. Further, the feed pawls 6 for horizontally transferring the multilayer cylindrical body A placed at the reference position to the bottom opening mechanism 10 are equally spaced on the roller chain 7 cyclically driven by the sprockets 8a, 8b and 8c. The roller conveyor 2 and the multi-layered cylindrical body A on the chain cover 7 can be pushed to the side to be transported at a height where they can be transported.
That is, the multilayer cylindrical body A is pushed by the roller chain 7 in a state where the cylindrical bottom portion is brought close to the fixed guide plate 5 by the roller conveyor 2 and transferred in the horizontal right direction.

続いて、前記送り爪6の右方向への移送動作により、水平横方向に強制的に押し出された多層筒体Aは、ローラ9、9間を通り、上下一対の移送ベルト11、11により挟持されながら後述する底開き機構部10へと移送される。移送ベルト11、11は、移送台12の後方(図2の上方)に立設された伝動装置取付板13の後方に設置されている。なお、この際の多層筒体Aの移送周期は、後述する底開き機構部10の周期と同期するよう設定されている。   Subsequently, the multilayer tubular body A forcibly pushed out in the horizontal direction by the transfer operation of the feed claw 6 in the right direction passes between the rollers 9 and 9 and is nipped by the upper and lower transfer belts 11. It is transported to the bottom opening mechanism 10 to be described later. The transfer belts 11, 11 are installed behind a transmission mounting plate 13 which is provided at the rear (upper side in FIG. 2) of the transfer base 12. The transfer cycle of the multilayer cylinder A at this time is set to be synchronized with the cycle of the bottom opening mechanism 10 described later.

底開き機構部10による多層筒体Aの底開き工程(後述)が終了すると、多層筒体Aはローラ14、14間を通り、底貼り機構部(図示せず)へと送り出される。なお、符号11a、11aは移送ベルト11を巻掛する左右一対のプーリー、符号11bはテンションローラ、符号15は底開きが十分でなかった筒体を製造ラインから取り除くための底剥がし不良筒体排除坂である。   When the bottom opening process (described later) of the multilayer cylinder A by the bottom opening mechanism 10 is completed, the multilayer cylinder A passes between the rollers 14 and is sent out to the bottom pasting mechanism (not shown). The reference numerals 11a and 11a denote a pair of left and right pulleys around which the transfer belt 11 is wound, the reference numeral 11b denotes a tension roller, and the reference numeral 15 denotes a bottom peeling defective cylinder for removing a cylinder whose opening is insufficient. It is a slope.

次に、底開き機構部10について図4及び図5に基づき説明する。
底開き機構部10は、水平横方向に送られてくる多層筒体Aを間にして上下に対向するよう配設された二組のユニットからなり、それぞれが同一の構成からなる伝動装置(伝動機構)10Aと吸着装置(吸着機構)10Bとを備える。
Next, the bottom opening mechanism 10 will be described based on FIGS. 4 and 5.
The bottom opening mechanism portion 10 is composed of two sets of units disposed to face each other vertically with the multilayer cylindrical body A sent in the horizontal direction in between, and each has a transmission device (a transmission (a transmission) Mechanism) 10A and an adsorption device (adsorption mechanism) 10B.

上側ユニットについて説明すると、伝動装置取付板13に所定の軸間距離を空けて左右水平に配設された一対のスプロケット16、16にローラチェーン17を巻掛けしてなる二基の伝動装置が、図示の如く所定間隔をもって上下平行に配設されていて、同期装置(図示せず)により、スプロケット16の回転、ローラチェーン17の走行及び後述する吸盤18の循環が、前記ローラコンベア2から移送ベルト11、11によって水平横方向に送られて来る多層筒体Aの進行に同期するよう予め設定されている。   Regarding the upper unit, two transmissions formed by winding a roller chain 17 around a pair of sprockets 16 and 16 horizontally disposed horizontally with a predetermined axial distance between the transmission attachment plate 13 are as follows: As shown in the drawing, they are disposed vertically in parallel at predetermined intervals, and rotation of the sprocket 16, rotation of the roller chain 17, and circulation of the suction cups 18 described later are transferred from the roller conveyor 2 by the synchronization device (not shown). It is preset to be synchronized with the progress of the multilayer cylindrical body A sent in the horizontal direction by 11, 11.

なお、本実施態様においては上下ユニットのそれぞれに二基の伝動装置10A、10Aを設けているが、いずれか一方の伝動装置10A(本実施態様では、上側ユニットにおける図示上部の伝動装置、下側ユニットにおける図示下部の伝動装置)は、後述する吸着装置10Bのより安定した動作を実現するためであって、伝動装置が一基であっても請求項1及び2に記載の発明の実施については必要不可欠な構成要素ではない。   In the present embodiment, although the two transmissions 10A and 10A are provided in each of the upper and lower units, one of the transmissions 10A (in the present embodiment, the transmission in the upper portion of the upper unit shown in the drawing, the lower side) The transmission in the lower part of the unit (in the lower part of the drawing) is for realizing more stable operation of the adsorption device 10B described later, and even if there is only one transmission, the invention according to claims 1 and 2 is not It is not an essential component.

吸着装置(吸着機構)10Bは、吸盤18及びエアシリンダー19等を備えていて、前記伝動装置10Aの動作と連係する。すなわち、その一方端がローラチェーン17と回動可能に連結し、他方側が後述するシリンダー取付フレーム23と連結するアタッチメント27を伝動装置10Aと吸着装置10B間に介装する。このアタッチメント27の一方端部にはローラチェーン17のブッシュを回動可能に貫通するピン28が設けられていて、これにより、ローラチェーン17とアタッチメント27とは回動可能に連結されている。上記構成によって、ローラチェーン17の走行軌跡がアタッチメント27を介して吸着装置10Bに伝わり、ローラチェーン17の循環走行に連動して吸着装置10Bは、スプロケット16、16の軸巾間で左右水平に移動し、ローラチェーン17の張設巾間で半円軌跡を描くように上昇又は下降移動する。   The adsorption device (adsorption mechanism) 10B is provided with a suction cup 18, an air cylinder 19 and the like, and cooperates with the operation of the transmission 10A. That is, an attachment 27 is rotatably connected at one end to the roller chain 17 and is connected at the other end to a cylinder mounting frame 23 described later, interposed between the transmission device 10A and the suction device 10B. A pin 28 rotatably penetrates the bush of the roller chain 17 is provided at one end of the attachment 27, whereby the roller chain 17 and the attachment 27 are rotatably coupled. With the above configuration, the traveling path of the roller chain 17 is transmitted to the suction device 10B via the attachment 27, and the suction device 10B moves horizontally between the axial widths of the sprockets 16, 16 in conjunction with the circulation travel of the roller chain 17.

そして、本実施態様に係る袋筒体の底開き装置にあっては、左右一対のスプロケット16、16の軸間でのローラチェーン17、17の走行は水平状態が保たれており、これに連動する上下吸盤18、18もこの区間は多層筒体Aとの平行状態を保ちながらその進行に同調して水平移動する。このような水平移動する十分な同調区間(時間)の中で、上下吸盤18、18と多層筒体Aの上下面との確実な吸着が実施され、上側吸盤18の上昇開始点で下側吸盤18の下降開始点からの強力な吸引が実施される。したがって、本装置をヒートシール機の後部で底貼り機の底開き装置の前に設置し接続することにより、外層紙筒体A1と内層プラスチック筒体A2シール内着を確実に剥がしてから底貼り機に多層筒体Aを供給することができるので、手作業に頼ることなく、製袋工程の完全自動化を実現することができる。   And in the bottom opening device of the bag cylinder according to the present embodiment, the traveling of the roller chains 17, 17 between the shafts of the pair of left and right sprockets 16, 16 is kept horizontal and interlocked with this The upper and lower suction cups 18, 18 also move horizontally in synchronization with the progress of the section while maintaining the parallel state with the multilayer cylindrical body A. In such a sufficiently synchronized section (time) to move horizontally, reliable suctioning between the upper and lower suction cups 18, 18 and the upper and lower surfaces of the multilayer cylinder A is carried out, and the lower suction cup at the rising start point of the upper suction cup 18 A strong aspiration is performed from the 18 descent start points. Therefore, by installing and connecting this device at the rear of the heat sealing machine and in front of the bottom opening device of the bottom attaching machine, the outer layer paper cylinder A1 and the inner layer plastic cylinder A2 seal are securely peeled off and then attached to the bottom. Since the multilayer cylinder A can be supplied to the machine, full automation of the bag making process can be realized without relying on manual work.
