Such a pouch has a pouch in its hand as disclosed in, for example, the following Patent Document 1 after the two side films and the folded bottom film are sealed by the side seal part and the bottom seal part. In order to prevent the fingers from coming into contact with the edge part of the pouch, the side seal part is bent and the edge is turned inside, or as disclosed in Patent Document 2, a spout is provided on the pouch. Compression molding is performed in which the three-dimensional molding is performed cold.
そして、パウチを前述した加工、或いは成形に供する際には、その加工ラインにパウチを１枚ずつ搬送する必要がある。このような加工ラインにパウチを１枚ずつ搬送するシステムとして、パウチ群の最上位のパウチを分離し前方に送り出す分離手段と、パウチの先端が当接する位置決め用ストッパーと、パウチ分離手段が送り出したパウチに接触してさらに前方に送り出し、ストッパーに当接させる爪車と、ストッパーに位置決めされたパウチの上面を吸着して持ち上げる吸着部材を備え、揺動アームに支持された前記爪車が、送り出し位置と退避位置の間を揺動して移動し、前記送り出し位置がストッパーと吸着部材の間に設定され、前記退避位置がストッパーの停止面を越えた前方側に設定されているコンベアマガジン式空袋供給装置が提案されている（特許文献３）。 When the pouch is subjected to the above-described processing or molding, it is necessary to convey the pouch one by one to the processing line. As a system for conveying pouches one by one to such a processing line, separating means for separating the uppermost pouch of the pouch group and feeding it forward, a positioning stopper with which the tip of the pouch abuts, and the pouch separating means sent out A claw wheel that contacts the pouch and feeds further forward and comes into contact with the stopper, and a suction member that sucks and lifts the upper surface of the pouch positioned by the stopper, and the claw wheel supported by the swing arm is fed The conveyor magazine type empty space is moved between the position and the retracted position, the feed position is set between the stopper and the suction member, and the retracted position is set on the front side beyond the stop surface of the stopper. A bag supply device has been proposed (Patent Document 3).
しかしながら、特許文献３に開示されているコンベアマガジン式空袋供給装置は、以下のような解決すべき課題が存在する。即ち、（１）吸着手段によりパウチを吸着してパウチを取り出す際には、パウチ群から複数枚のパウチを同時に吸着して取り出してしまう虞がある。（２）パウチ群が前後方向にずらして積載されていることに起因して、パウチ群を支持する支持手段が過剰に大きくなり装置が大型化し、且つその装置を構成する手段、部材等を多数要し、装置が複雑化する虞がある。 However, the conveyor magazine type empty bag supply device disclosed in Patent Document 3 has the following problems to be solved. That is, (1) when a pouch is adsorbed by an adsorbing means and a pouch is taken out, a plurality of pouches may be adsorbed and taken out from the pouch group at the same time. (2) Due to the fact that the pouch group is stacked shifted in the front-rear direction, the support means for supporting the pouch group becomes excessively large, the apparatus becomes large, and there are a large number of means, members, etc. constituting the apparatus. In short, there is a risk that the apparatus becomes complicated.

以下、添付図面を参照して、本発明のパウチ搬送システムの好適実施形態について詳述する。 Hereinafter, a preferred embodiment of a pouch conveyance system of the present invention will be described in detail with reference to the accompanying drawings.
図１は、本発明のパウチ搬送システムを示し、パウチ２を１枚ずつ搬送するパウチ搬送システム全体の概略を示している。そして、図１の右側をパウチの搬送方向上流側とし、左側をパウチの搬送方向下流側として、パウチは、図１の右側から左側へ順次搬送される。パウチ取り出し供給部１６は、パウチ２を積載して支持する支持手段１８、支持手段１８からパウチ２を取り出す吸着手段２０、及び取り出したパウチ２を送り出す送り手段２２を有している。本実施形態においては、送り手段は相互に密接して回転自在の一対のニップロールから成る送出ロール２２である。 FIG. 1 shows a pouch conveyance system of the present invention, and shows an outline of the entire pouch conveyance system for conveying the pouches 2 one by one. The right side of FIG. 1 is the upstream side in the pouch transport direction and the left side is the downstream side of the pouch transport direction, and the pouches are sequentially transported from the right side to the left side in FIG. The pouch take-out supply unit 16 includes support means 18 for loading and supporting the pouch 2, suction means 20 for taking out the pouch 2 from the support means 18, and feed means 22 for sending out the taken out pouch 2. In this embodiment, the feeding means is a feeding roll 22 composed of a pair of nip rolls that are rotatable in close contact with each other.
支持手段１８は、底面１９に矩形形状の開口部２６が形成され、積載されたパウチ群をその支持部１９ａ、１９ｂで支持する。
また、吸着手段２０は、ロッド３０、及びロッド３０の先端に取り付けられた吸着部３２を有し、パウチを吸着する吸着部３２が、前述した支持手段１８の底面１９の開口部２６から最下部のパウチを取り出すことができるように、適宜カム機構、クランク機構等によって駆動される。また、吸着部３２は図示しない真空ポンプに接続され、適宜、吸着、非吸着状態とされる。
そして、吸着手段２０の吸着部３２を、支持手段１８内のパウチ群の最下方のパウチに吸着させ、上流側に水平移動してパウチを屈曲させた後（屈曲位置）、前記吸着部３２を下方に移動して屈曲させたパウチを支持部材１８の開口部２６から引き下ろし（引き下ろし位置）、前記吸着部３２をパウチの搬送方向下流側に移動して（送り出し位置）、送り出しロール２２間に供給する（図２参照）。
このように、パウチを下方に屈曲して支持手段１８の開口部２６内から引き下ろすことにより、最下方のパウチを重複することなく一枚ずつ取り出して下流側に搬送することができる。
The support means 18 is formed with a rectangular opening 26 on the bottom surface 19 and supports the stacked pouch group by the support portions 19a and 19b.
Further, the suction means 20 includes a rod 30 and a suction portion 32 attached to the tip of the rod 30, and the suction portion 32 that sucks the pouch is the lowermost part from the opening 26 of the bottom surface 19 of the support means 18 described above. It is appropriately driven by a cam mechanism, a crank mechanism or the like so that the pouch can be taken out. Further, the suction unit 32 is connected to a vacuum pump (not shown) and is appropriately in a suction and non-adsorption state.
Then, the suction portion 32 of the suction means 20 is attracted to the lowermost pouch of the pouch group in the support means 18 and horizontally moved upstream to bend the pouch (bending position), and then the suction portion 32 is moved. The pouch moved downward and bent is pulled down from the opening 26 of the support member 18 (down position), and the suction part 32 is moved downstream in the conveyance direction of the pouch (out position) to be supplied between the supply rolls 22. (See FIG. 2).
Thus, by bending the pouch downward and pulling it down from the opening 26 of the support means 18, the lowermost pouch can be taken out one by one without being overlapped and conveyed downstream.
さらに、送出ロール２２は、支持手段１８よりもパウチの搬送方向下流側に位置し、送出ロール２２間の搬送位置は、支持手段１８の底面１９の開口部２６よりも低い位置に位置する。そして、送出ロール２２は、前述した支持手段１８から吸着手段２０によって取り出したパウチ２を下流側に送り出す。 Further, the delivery roll 22 is located downstream of the support means 18 in the pouch conveyance direction, and the delivery position between the delivery rolls 22 is located at a position lower than the opening 26 of the bottom surface 19 of the support means 18. Then, the delivery roll 22 sends out the pouch 2 taken out from the support means 18 by the suction means 20 to the downstream side.
本発明のパウチの搬送システムにおいては、図１に示すように、前述したパウチ取り出し供給部１６の下流側に、重複パウチ除去部３６を配設することが好ましい。
この重複パウチ除去部３６は案内手段４８を有し、送出ロール２２から送出されたパウチを下流側に送り出す第一案内ロール５０、第一案内ロール５０から送り出されたパウチ２の進行方向を下方に屈曲させて案内する第一案内部材５２、及び第一案内部材５２により案内されたパウチを、後述する吸盤ロール４０と吸着発生ロール４４の間に送り出す第二案内ロール５４を有する。この第一案内ロール５０及び第二案内ロール５４はいずれも相互に密接して回転する一対のニップロールである。図示の実施形態においては、重複パウチ除去部３６には、外周面に吸盤３８を有する吸盤ロール４０、吸盤ロール４０の下流側に順次配設された吸着解除ガイド４２、吸着発生ロール４４、及び吸着発生ロール４４の下流側に配設された排出ロール４６を有する。
図３に示すように、吸盤ロール４０は複数列設けられ、その外周面に吸盤３８を幅方向、外周方向に等間隔に有している。図示の実施形態においては各吸盤ロール４０のロール幅に対して３個形成している。
また、吸着発生ロール４４は、吸盤ロール４０の右側（上流側）下方位置で、吸盤ロール４０の吸盤３８に搬送されるパウチと密着して回転する。
さらに、吸着解除ガイド４２は、前述した各吸盤ロール４０の側面にそれぞれ一対で固定され、側面視で略三角形状を呈する板状部材である。そして、それぞれ一対の板状部材（吸着解除ガイド４２）に補助ロール５６を、吸盤ロール４０の左側（下流側）上方位置に位置するように回転自在に取り付けられている。また、図１に示すように、補助ロール５６の左側（下流側）上方には、搬送されるパウチの進行方向を上方に屈曲させて案内する第二案内部材５８が配設されている。また、吸着発生ロール４４の下流側に配設される排出ロール４６は、吸盤ロール４０による主搬送路から分岐した位置に配設され、相互に密接して回転する一対のニップロールであり、下方には排出パウチ回収具６０が設置されている。
In the pouch conveyance system of the present invention, as shown in FIG. 1, it is preferable to dispose a duplicate pouch removal unit 36 on the downstream side of the pouch take-out supply unit 16 described above.
This overlapping pouch removing unit 36 has a guide means 48, and the first guide roll 50 that sends the pouch delivered from the delivery roll 22 to the downstream side, and the traveling direction of the pouch 2 delivered from the first guide roll 50 downward. A first guide member 52 that is bent and guided, and a second guide roll 54 that sends out a pouch guided by the first guide member 52 between a suction cup roll 40 and a suction generation roll 44 described later. The first guide roll 50 and the second guide roll 54 are both a pair of nip rolls that rotate in close contact with each other. In the illustrated embodiment, the overlapping pouch removal unit 36 includes a suction cup roll 40 having a suction cup 38 on the outer peripheral surface, a suction release guide 42 sequentially disposed downstream of the suction cup roll 40, a suction generation roll 44, and a suction A discharge roll 46 is provided on the downstream side of the generation roll 44.
As shown in FIG. 3, the suction cup rolls 40 are provided in a plurality of rows, and the suction cups 38 are provided on the outer peripheral surface thereof at equal intervals in the width direction and the outer peripheral direction. In the illustrated embodiment, three pieces are formed for the roll width of each sucker roll 40.
Further, the suction generation roll 44 rotates in close contact with the pouch conveyed to the suction cup 38 of the suction cup roll 40 at a position below the right side (upstream side) of the suction cup roll 40.
Further, the suction release guides 42 are plate-like members that are fixed in pairs to the side surfaces of the respective suction cup rolls 40 and have a substantially triangular shape in a side view. The auxiliary roll 56 is rotatably attached to the pair of plate-like members (adsorption release guide 42) so as to be positioned on the left side (downstream side) of the suction cup roll 40. As shown in FIG. 1, a second guide member 58 is provided on the left side (downstream side) of the auxiliary roll 56 to guide the traveling direction of the pouch to be bent upward. The discharge roll 46 disposed on the downstream side of the suction generation roll 44 is a pair of nip rolls disposed at a position branched from the main conveyance path by the suction cup roll 40 and rotating in close contact with each other. A discharge pouch collection tool 60 is installed.
さらに、本発明のパウチの搬送システムにおいては、図１に示すように、前述した重複パウチ除去部３６の下流には間隔調整部６２が配設されているのが好ましい。
この間隔調整部６２は、図４示すように上流側の入口ロール６４、入口ロール６４よりも周速度が低速の下流側の出口ロール６６、及び入口ロール６４と出口ロール６６間に屈曲制限手段６８を有する。入口ロール６４及び出口ロール６６は、共に相互に密接して回転する一対のニップロールである。入口ロール６４と出口ロール６６の周速度は、出口ロール６６が低速で、その速度比は１．２乃至１．４が好ましい。入口ロール６４と出口ロール６６間の距離はパウチ２の搬送方向長さの３０乃至６０％が好ましい。このように、入口ロール６４と出口ロール６６の周速度の速度比、入口ロール６４と出口ロール６６間の距離を規定することにより、出口ロール６６から送出された後に行う図示しない加工、成形を行う全体としての加工ラインの省スペース化を実現できると共に、間隔調整部６２におけるパウチの蛇行が防止される。また、間隔調整部６２は、２箇所等の複数箇所配設しもて良く、この場合、前述した速度比の範囲中で低い速度比に設定することが可能となり、よりパウチの蛇行が防止される。
尚、前述した屈曲制限手段６８は、入口ロール６４と出口ロール６６による仮想搬送位置よりも僅かに低い位置に設けられ、入口ロール６４と出口ロール６６間に水平に延びる屈曲制限面７０を有する。
Further, in the pouch conveyance system of the present invention, as shown in FIG. 1, it is preferable that a distance adjusting unit 62 is disposed downstream of the above-described overlapping pouch removing unit 36.
As shown in FIG. 4, the gap adjusting unit 62 includes an upstream inlet roll 64, a downstream outlet roll 66 having a lower peripheral speed than the inlet roll 64, and a bending limiting means 68 between the inlet roll 64 and the outlet roll 66. Have The inlet roll 64 and the outlet roll 66 are a pair of nip rolls that rotate in close contact with each other. As for the peripheral speed of the inlet roll 64 and the outlet roll 66, the outlet roll 66 is low, and the speed ratio is preferably 1.2 to 1.4. The distance between the inlet roll 64 and the outlet roll 66 is preferably 30 to 60% of the length of the pouch 2 in the conveying direction. In this way, by defining the speed ratio of the peripheral speeds of the inlet roll 64 and the outlet roll 66 and the distance between the inlet roll 64 and the outlet roll 66, processing and molding (not shown) performed after being sent from the outlet roll 66 are performed. Space saving of the processing line as a whole can be realized, and meandering of the pouch in the interval adjusting unit 62 is prevented. Further, the interval adjusting unit 62 may be arranged at a plurality of places such as two places. In this case, it is possible to set a low speed ratio within the range of the speed ratio described above, and the meandering of the pouch is further prevented. The
The bending limiting means 68 described above is provided at a position slightly lower than the virtual conveying position by the inlet roll 64 and the outlet roll 66 and has a bending limiting surface 70 extending horizontally between the inlet roll 64 and the outlet roll 66.
本発明のパウチ搬送システムは以上のように構成されており、以下そのシステムを用いて、積載されたパウチ群からパウチを１枚ずつ取り出すパウチの搬送システムについて説明する。
先ず、パウチ２を適宜手段により支持手段１８内に積載し、パウチ群として収容する。
The pouch conveyance system according to the present invention is configured as described above, and a pouch conveyance system that takes out one pouch at a time from the stacked pouch group using the system will be described below.
First, the pouch 2 is loaded into the support means 18 by appropriate means and accommodated as a pouch group.
次いで、図２に示すように、吸着着手段２０の吸着部３２を吸着状態とし、支持部１８の開口部２６の下流側（パウチの搬送方向下流側）に位置させ（図２（ａ）参照）、ニュートラル位置の吸着部３２を上方に移動し、支持部材１８の開口部２６内に位置させと共に、最下方のパウチを吸着する（図２（ｂ）参照）。次いで、前記吸着部３２を、パウチを吸着した状態で上流側に水平移動させ、吸着部３２とパウチとの吸着力、及び支持手段１８の上流側の内側壁面によるパウチの移動規制により、パウチを下方に屈曲する（図２（ｃ）参照）。その後、前記吸着部３２を下方に移動し、屈曲させたパウチを前記開口部２６から引き下ろす（図２（ｄ）参照）。次いで、前記吸着部３２によりパウチの搬送方向下流側に移動して、前記吸着部を非吸着状態とし、パウチ２を送り出しロール２２間に送り出す（図２（ｅ）参照）。その後、前記吸着手段２０の吸着部３２をニュートラル位置に戻し（図２（ａ）参照）、前記工程を順次繰り返す。 Next, as shown in FIG. 2, the suction portion 32 of the suction attachment means 20 is brought into the suction state, and is positioned downstream of the opening 26 of the support portion 18 (downstream in the pouch conveyance direction) (see FIG. 2A). ), The suction portion 32 at the neutral position is moved upward to be positioned in the opening portion 26 of the support member 18 and the lowermost pouch is sucked (see FIG. 2B). Next, the suction part 32 is horizontally moved to the upstream side while the pouch is sucked, and the pouch is moved by the suction force between the suction part 32 and the pouch and the movement restriction of the pouch by the inner wall surface on the upstream side of the support means 18. Bends downward (see FIG. 2C). Thereafter, the suction portion 32 is moved downward, and the bent pouch is pulled down from the opening portion 26 (see FIG. 2D). Next, the suction unit 32 moves to the downstream side in the conveyance direction of the pouch, puts the suction unit into a non-adsorption state, and sends out the pouch 2 between the delivery rolls 22 (see FIG. 2E). Thereafter, the suction portion 32 of the suction means 20 is returned to the neutral position (see FIG. 2A), and the above steps are sequentially repeated.
送出ロール２２に送出されたパウチ２は、次いで重複パウチ除去部３６に搬送される。
まず、送出ロール２２から送出されたパウチ２は、案内手段４８に案内される。即ち、送出ロール２２から送出されたパウチ２は、第一案内ロール５０によりパウチの搬送方向下流側に送出され、第一案内部材５２によりその進行方向が下方に屈折される。そして、パウチは、第二案内ロール５４を介して吸盤ロール４０と吸着発生ロール４４との間に搬送され、吸盤ロール４０の外周面に形成された吸盤３８に吸着される。これにより、吸盤ロール４０と吸着発生ロール４４との間を通過したパウチ２は、吸盤ロール４４の外周面の吸盤３８に吸着した状態で時計方向、即ちパウチの搬送方向下流側に搬送される（主搬送路）。そして、吸盤３８に吸着したパウチ２は、所定角度、時計方向に回転して搬送された後に、吸着解除ガイド４２の底面と吸盤ロール４０とが交差する剥離地点Ｐ（図１参照）において、パウチ２の先端から吸着解除ガイド４２の下面に漸次係合して吸盤３８から漸次剥離されると共に、補助ロール５６を介して第二案内部材５８によりその進行方向が水平方向に屈折させられる。
The pouch 2 delivered to the delivery roll 22 is then conveyed to the duplicate pouch removal unit 36.
First, the pouch 2 delivered from the delivery roll 22 is guided to the guide means 48. That is, the pouch 2 delivered from the delivery roll 22 is delivered to the downstream side of the pouch conveyance direction by the first guide roll 50, and the traveling direction thereof is refracted downward by the first guide member 52. The pouch is conveyed between the suction cup roll 40 and the suction generation roll 44 via the second guide roll 54 and is sucked by the suction cup 38 formed on the outer peripheral surface of the suction cup roll 40. As a result, the pouch 2 that has passed between the suction cup roll 40 and the suction generation roll 44 is conveyed in the clockwise direction, that is, downstream in the conveyance direction of the pouch while being adsorbed by the suction cup 38 on the outer peripheral surface of the suction cup roll 44 ( Main transport path). The pouch 2 adsorbed on the suction cup 38 is rotated clockwise by a predetermined angle, and then conveyed at a peeling point P (see FIG. 1) where the bottom surface of the suction release guide 42 and the suction cup roll 40 intersect. 2 is gradually engaged with the lower surface of the suction release guide 42 and gradually separated from the suction cup 38, and its traveling direction is refracted in the horizontal direction by the second guide member 58 via the auxiliary roll 56.
また、支持手段１８より吸着手段２０を用いてパウチ２を取り出し、送出ロール（送り手段）２２より送出したパウチ２が上下に重複していた場合であっても、吸盤ロール４０に形成された吸盤３８は上側のパウチのみに吸着し、下側のパウチは吸盤３８により吸着されることがなく、主搬送路から吸盤ロール４０と吸着力発生ロール４４の下流側に配設された排出ロール４６に案内され、その下方に位置する排出パウチ回収具６０に回収される。 Further, even when the pouch 2 is taken out from the support means 18 using the suction means 20 and the pouch 2 sent out from the sending roll (feeding means) 22 overlaps vertically, the sucker formed on the sucker roll 40. 38 is adsorbed only on the upper pouch, and the lower pouch is not adsorbed by the suction cup 38, and is discharged from the main conveyance path to the discharge roll 46 disposed downstream of the suction cup roll 40 and the suction force generation roll 44. It is guided and collected by the discharge pouch collection tool 60 located below.
次いで、前述した第二案内部材５８により屈折されたパウチ２は、間隔調整部６２に搬送される。
第二案内部材５８により屈折されたパウチ２は、その先端が入口ロール６４に到達すると共に、漸次パウチの搬送方向下流側に送出される。そして、入口ロール６４から送出されたパウチ２の先端が出口ロール６６に到達すると、出口ロール６６の周速度が入口ロール６４の周速度よりも低速で、入口ロール６４と出口ロール６６間の距離をパウチ２の搬送方向長さよりも短く、さらに、入口ロール６４と出口ロール６６間に屈曲制限面７０を有する片側屈曲制限手段６８が配設されており、出口ロール６６に到達したパウチ２は上側に凸形状に屈曲される（図１参照）。これにより、搬送されるパウチ２に遅延が生じても、出口ロール６６から送出された後のパウチの搬送間隔ｙは、入口ロール６４に到達する前のパウチ搬送間隔ｘよりも短くなる。このため、前述したように出口ロール６６から送出された後に行う図示しない加工、成形を行う全体としての加工ラインの省スペース化を実現できる。
Next, the pouch 2 refracted by the second guide member 58 described above is conveyed to the interval adjustment unit 62.
The pouch 2 refracted by the second guide member 58 reaches the inlet roll 64 and is sent out gradually downstream in the conveying direction of the pouch. When the tip of the pouch 2 delivered from the inlet roll 64 reaches the outlet roll 66, the peripheral speed of the outlet roll 66 is lower than the peripheral speed of the inlet roll 64, and the distance between the inlet roll 64 and the outlet roll 66 is increased. One-side bending limiting means 68 having a bending limiting surface 70 is disposed between the inlet roll 64 and the outlet roll 66 and is shorter than the length of the pouch 2 in the conveying direction. Bent into a convex shape (see FIG. 1). Thereby, even if a delay occurs in the transported pouch 2, the transport interval y of the pouch after being sent out from the outlet roll 66 is shorter than the pouch transport interval x before reaching the inlet roll 64. For this reason, as described above, it is possible to realize space saving of the processing line as a whole for performing processing and molding (not shown) performed after being fed from the outlet roll 66.
図５は、本発明のパウチ搬送システムにおけるパウチ取り出し供給部１６の他の実施形態を示し、支持手段１８の下面に形成された開口部２６内に屈曲手段７２を配設している。この屈曲手段７２は、回転ロール部７４と、回転ロール部７４の外周面の特定領域に、回転軸方向に延びる係止突部７６から構成されている。また、屈曲手段７２は図示しないサーボモータ等の適宜駆動手段により、所定の周速度で時計方向に回転し、係止突部７６の先端部が支持手段１８内の最下方のパウチ２と開口部２６内で接触する。 FIG. 5 shows another embodiment of the pouch take-out supply unit 16 in the pouch conveyance system of the present invention, and a bending means 72 is disposed in an opening 26 formed in the lower surface of the support means 18. The bending means 72 includes a rotating roll portion 74 and a locking protrusion 76 extending in the rotation axis direction in a specific region on the outer peripheral surface of the rotating roll portion 74. Further, the bending means 72 is rotated clockwise at a predetermined peripheral speed by an appropriate driving means such as a servo motor (not shown), and the distal end portion of the locking projection 76 is the lowermost pouch 2 and the opening in the support means 18. 26 in contact.
そして、このパウチ取り出し供給部１６は、吸着手段２０の吸着部３２がニュートラル位置（図５（ａ））から上昇してパウチを吸着する前に、屈曲手段７２を時計方向に回転させて係止突部７６を支持手段１８の最下方のパウチ２に接触させ、前記係止突部７６とパウチの摩擦力、及び支持手段１８の上流側の内側壁面によるパウチの移動規制により、パウチを下方に屈曲させた後、前記パウチ２を吸着部３２により吸着する（図５（ｂ））。次いで、さらに、屈曲手段７２を時計方向に回転させ、係止突部７６とパウチ２との接触を開放すると共に、吸着部３２を引き下ろし位置に降下させ、パウチ２を１枚だけ引き下ろす（図５（ｃ））。次いで、この状態から、吸着部３２を送り出し位置に水平に下流側に移動させ、吸着部３２を非吸着状態として、パウチ２を搬送方向下流側の送出ロール２２に送り出す（図５（ｄ））。その後、前記吸着手段２０の吸着部３２をニュートラル位置に、屈曲手段７４を時計方向に回転して回転初期の位置にそれぞれ戻し、前記工程を順次繰り返す（図５（ａ））。
このように構成することにより、最下方のパウチを重複することなく、より確実に一枚ずつ取り出して下流側に搬送することができる。
また、屈曲手段７２は、少なくとも係止突部７６を摩擦係数の比較的大きい材質、例えばシリコン等で構成することが好ましい。
Then, the pouch take-out supply unit 16 is engaged by rotating the bending unit 72 clockwise before the suction unit 32 of the suction unit 20 rises from the neutral position (FIG. 5A) and sucks the pouch. The protrusion 76 is brought into contact with the lowermost pouch 2 of the support means 18, and the pouch is moved downward by the frictional force between the locking protrusion 76 and the pouch and the movement of the pouch by the inner wall surface on the upstream side of the support means 18. After being bent, the pouch 2 is adsorbed by the adsorbing portion 32 (FIG. 5B). Next, the bending means 72 is further rotated in the clockwise direction to release the contact between the locking projection 76 and the pouch 2, and the suction portion 32 is lowered to the lower position, so that only one pouch 2 is pulled down (see FIG. 5 (c)). Next, from this state, the suction portion 32 is moved horizontally to the delivery position downstream, the suction portion 32 is brought into a non-adsorption state, and the pouch 2 is sent to the delivery roll 22 on the downstream side in the transport direction (FIG. 5D). . Thereafter, the suction portion 32 of the suction means 20 is rotated to the neutral position, and the bending means 74 is rotated clockwise to return to the initial rotation position, and the above steps are sequentially repeated (FIG. 5A).
With this configuration, the lowermost pouches can be taken out one by one more reliably and conveyed downstream without overlapping.
Further, the bending means 72 preferably comprises at least the locking projection 76 made of a material having a relatively large friction coefficient, such as silicon.
尚、本実施形態においては、パウチ２を下方に屈曲させ、パウチ２を吸着部３２で吸着した後（図５（ｂ）参照）、吸着部３２を吸着位置から水平に上流側に移動させても良い。これにより、吸着部３２と係止突条７６との距離が相対的に短くなり、吸着部３２と係止突部７６との間（下流側）にも、パウチ２が下方に屈曲した状態とすることができ、より一層確実に、最下方のパウチが重複することなく一枚ずつ取り出して下流側に搬送することができる。 In this embodiment, after the pouch 2 is bent downward and the pouch 2 is adsorbed by the adsorbing portion 32 (see FIG. 5B), the adsorbing portion 32 is moved horizontally from the adsorption position to the upstream side. Also good. As a result, the distance between the suction portion 32 and the locking projection 76 becomes relatively short, and the pouch 2 is bent downward between the suction portion 32 and the locking projection 76 (downstream side). The lowermost pouches can be taken out one by one and transported downstream without fail.
図６は、本発明のパウチ搬送システムにおけるパウチ取り出し供給部１６の更に他の実施形態を示し、屈曲手段７２を時計方向に回転させた後、屈曲手段７４を反時計方向に回転させ、前記屈曲手段７２の回転ロール７４の外周面に設けた係止突部７６を揺動させている。
そして、このパウチ取り出し供給部１６は、吸着手段２０の吸着部３２がニュートラル位置（図６（ａ））から上昇してパウチを吸着する前に、屈曲手段７２を時計方向に回転させて係止突部７６を支持手段１８の最下方のパウチ２に接触させ、前記係止突部７６とパウチの摩擦力、及び支持手段１８の上流側の内側壁面によるパウチの移動規制により、パウチを下方に屈曲させた後、前記パウチ２を吸着部３２により吸着し（図６（ｂ））、次いで、前記屈曲手段７２を反時計方向に回転させて、前記係止突部７６とパウチの摩擦力、及び吸着部３２とパウチとの吸着力により、パウチ２を吸着部３２と係止突条７６との間でも下方に屈曲させる（図６（ｃ））。次いで、この状態から、吸着部３２を下方に引き下ろし位置に降下させ、屈曲手段７２を反時計方向に回転させて係止突部７６とパウチ２との接触を開放した後（図６（ｄ））、吸着部３２を送り出し位置に水平に下流側に移動させ、吸着部３２を非吸着状態として、パウチ２を搬送方向下流側の送出ロール２２に送り出す（図６（ｅ））。その後、前記吸着手段２０の吸着部３２をニュートラル位置に、屈曲手段７４を時計方向に回転して回転初期の位置にそれぞれ戻し（図６（ａ）参照）、前記工程を順次繰り返す。このように構成することにより、最下方のパウチを重複することなく、より一層確実に一枚ずつ取り出して下流側に搬送することができる。
FIG. 6 shows still another embodiment of the pouch take-out and supply unit 16 in the pouch conveyance system of the present invention. After the bending means 72 is rotated in the clockwise direction, the bending means 74 is rotated in the counterclockwise direction, and the bending is performed. The locking projection 76 provided on the outer peripheral surface of the rotating roll 74 of the means 72 is swung.
Then, the pouch take-out supply unit 16 is engaged by rotating the bending unit 72 clockwise before the suction unit 32 of the suction unit 20 rises from the neutral position (FIG. 6A) and sucks the pouch. The protrusion 76 is brought into contact with the lowermost pouch 2 of the support means 18, and the pouch is moved downward by the frictional force between the locking protrusion 76 and the pouch and the movement of the pouch by the inner wall surface on the upstream side of the support means 18. After bending, the pouch 2 is adsorbed by the adsorbing portion 32 (FIG. 6B), and then the bending means 72 is rotated counterclockwise so that the frictional force between the locking projection 76 and the pouch, The pouch 2 is bent downward between the suction portion 32 and the locking protrusion 76 by the suction force between the suction portion 32 and the pouch (FIG. 6C). Next, from this state, after the suction portion 32 is pulled down and lowered to the position, the bending means 72 is rotated counterclockwise to release the contact between the locking projection 76 and the pouch 2 (FIG. 6D). ), The suction part 32 is moved horizontally downstream to the delivery position, the suction part 32 is brought into a non-suction state, and the pouch 2 is sent to the delivery roll 22 on the downstream side in the transport direction (FIG. 6E). Thereafter, the suction portion 32 of the suction means 20 is rotated to the neutral position, and the bending means 74 is rotated clockwise to return to the initial rotation position (see FIG. 6A), and the above steps are sequentially repeated. By configuring in this way, the lowermost pouches can be taken out one by one more reliably and conveyed downstream without overlapping.
尚、本実施形態においては、前述した屈曲手段７２を反時計方向に回転させて、パウチ２を吸着部３２と係止突条７６との間でも下方に屈曲させる際に（図６（ｃ）参照）、前記屈曲と同時に、或いは屈曲後に吸着部３２を吸着位置からパウチの搬送方向上流側に水平移動させても良い。これにより、吸着部３２と係止突条７６との距離が相対的に短くなり、係止突部７６とパウチ２との接触部より搬送方向下流部分の下側に屈曲がより一層屈曲した状態となるため、最下方のパウチを重複することなく、より一層確実に一枚ずつ取り出して下流側に搬送することができる。 In the present embodiment, when the bending means 72 described above is rotated counterclockwise, the pouch 2 is bent downward even between the suction portion 32 and the locking protrusion 76 (FIG. 6C). Reference), the suction portion 32 may be horizontally moved from the suction position to the upstream side in the conveyance direction of the pouch simultaneously with the bending or after the bending. As a result, the distance between the suction portion 32 and the locking protrusion 76 becomes relatively short, and the bending is further bent below the downstream portion in the transport direction from the contact portion between the locking protrusion 76 and the pouch 2. Therefore, the lowermost pouches can be taken out one by one more reliably and conveyed downstream without overlapping.
