本発明は、青果物用包装袋を用いた青果物包装方法及びこれに用いる青果物用包装袋の製造方法に関する。さらに詳しくは、包装装置と青果物用包装袋とを備え、袋本体部と、この袋本体部の袋開口部の片側から張り出す張出体とを有し、この張出体を前記袋開口部に沿って横断する易切断加工部を設けることで、この張出体を前記袋本体部側の張出部と包装機に取り付けられる耳部とに区切ってある青果物用包装袋を用いた青果物包装方法及びこれに用いる青果物用包装袋の製造方法に関する。 The present invention relates to a fruit and vegetable packaging method using a fruit and vegetable packaging bag and a method for manufacturing a fruit and vegetable packaging bag used thereto. More specifically, it is provided with a packaging device and a packaging bag for fruits and vegetables, and has a bag main body and an overhanging body that projects from one side of the bag opening of the bag main body, and the overhanging body is referred to as the bag opening. By providing an easy-to-cut processing portion that crosses along the above, fruit and vegetable packaging using a fruit and vegetable packaging bag that separates the overhanging body into an overhanging portion on the bag body side and an ear portion attached to a packaging machine. The present invention relates to a method and a method for manufacturing a packaging bag for fruits and vegetables used therein.

上述のような包装袋を用いる青果物用包装装置としては、次の特許文献1、2に記載のものが知られている。同文献1の装置によれば、図4,9に示すように、保持部303の係止孔305を1本のピンに貫通させて、包装袋を支持している。そして、開口302から風が送られて袋が膨らみ、青果物を開口302から包装袋に投入して、ミシン目304で包装袋がちぎれて封入が完了する。特許文献2の図2,4,5に示すものもピンの数は2本であるが同様である。また、特許文献2の図7~9に示すものは、幅広の包装袋が横に配置されて風が吹き込まれる形式となっている。 As the packaging device for fruits and vegetables using the packaging bag as described above, the ones described in the following Patent Documents 1 and 2 are known. According to the apparatus of the same document 1, as shown in FIGS. 4 and 9, the locking hole 305 of the holding portion 303 is penetrated through one pin to support the packaging bag. Then, wind is sent from the opening 302 to inflate the bag, and fruits and vegetables are put into the packaging bag through the opening 302, and the packaging bag is torn at the perforation 304 to complete the encapsulation. The number of pins shown in FIGS. 2, 4 and 5 of Patent Document 2 is the same, though the number of pins is two. Further, in the case shown in FIGS. 7 to 9 of Patent Document 2, a wide packaging bag is arranged sideways and a wind is blown into the bag.

ところで、図5(b)に比較例を掲載するが、ミシン目15だけを設けた場合には、このミシン目15の部分からフィルムが引き裂かれ、符合13axに示すようなフィルム断片が不規則に現れるおそれがある(写真9~10参照)。このような場合、フィルム断片13axが風Bが袋開口部12に届かずに、包装袋が開かないこととなる不都合があった。また、手で袋の口を開けて青果物等を挿入する場合も、フィルム断片が発生した場合は、袋の開口部をふさぎ、作業効率の低下するおそれがあっった。 By the way, although a comparative example is shown in FIG. 5B, when only the perforation 15 is provided, the film is torn from the perforation 15 portion, and the film fragment as shown by the sign 13ax is irregularly formed. It may appear (see photos 9 to 10). In such a case, the film fragment 13ax has the inconvenience that the wind B does not reach the bag opening 12 and the packaging bag does not open. Further, even when the mouth of the bag is opened by hand and fruits and vegetables are inserted, if a film fragment is generated, the opening of the bag may be blocked and the work efficiency may be lowered.

By providing an easy-to-cut portion that crosses along the bag opening, the overhanging body is divided into an overhanging portion on the bag main body side and an ear portion attached to the packaging machine. A melt-processed portion is provided along the easy-cutting-processed portion at the protruding portion.

同構成によれば、図5(a)に示すように溶融加工部を設けたことにより、例えミシン目等の易切断部から引き裂きが発生しても、その引き裂きは溶融加工部によりストップされる。その結果、図5(b)、図9に示すように、耳部にフィルム断片が残ることもない。したがって、袋開口部から風が吹き込まれ、包装袋はより確実に膨らむこととなる。また、手で袋開口部を広げて内容物を挿入する場合においてもフィルム断片が妨げになることもない。 According to the same configuration, by providing the melt-processed portion as shown in FIG. 5 (a), even if tearing occurs from an easily cut portion such as a perforation, the tearing is stopped by the melt-processed portion. .. As a result, as shown in FIGS. 5 (b) and 9, no film fragment remains in the selvage. Therefore, the wind is blown from the opening of the bag, and the packaging bag is inflated more reliably. Further, even when the bag opening is widened by hand and the contents are inserted, the film fragment does not interfere.

上記構成において、前記易切断加工部はミシン目により形成するとよい。また、溶融加工部はヒーターにより溶融されたものとすることで、加工を容易に行うことができる。この包装袋は、袋開口部に風が吹き込まれて前記袋本体が拡張し、または、袋開口部が手で押し広げられて、内容物が前記袋本体に挿入されるものである。 In the above configuration, the easy-to-cut portion may be formed by perforations. Further, by making the melt-processed portion melted by a heater, the processing can be easily performed. In this packaging bag, wind is blown into the bag opening to expand the bag body, or the bag opening is manually expanded to insert the contents into the bag body.

一方、上記目的を達成するための青果物用包装袋の製造方法の特徴は、袋本体部と、この袋本体部の袋開口部の片側から張り出す張出体とを有し、この張出体を前記袋開口部に沿って横断する易切断加工部を設けることで、この張出体を前記袋本体部側の張出部と包装機に取り付けられる耳部とに区切ってあり、第1フィルム、第2フィルムを上部が張り出すようにずらせて重ね、張出体と連続する袋本体部を形成してある方法であって、溶融加工機により前記張出部に前記易切断加工部に沿って溶融加工部を設け、サイドシール切断機により前記第1、第2フィルムの突き合わせ体を溶断すると共にサイドシールがなされて袋が形成され、複数の青果物用包装袋を積層して前記耳部で貼り合わせることにある。
On the other hand, a feature of the method for manufacturing a packaging bag for fruits and vegetables for achieving the above object is to have a bag main body and an overhanging body overhanging from one side of the bag opening of the bag main body, and this overhanging body. This overhanging body is divided into an overhanging portion on the bag main body side and an ear portion attached to a packaging machine by providing an easy-cutting processed portion that crosses the bag opening. , The second film is overlapped by shifting it so that the upper part is overhanging, and a bag main body portion continuous with the overhanging body is formed. A melt-processed portion is provided, and the butted bodies of the first and second films are melted by a side seal cutting machine, and side seals are made to form a bag. It is to stick them together.

同製造方法において、前記易切断加工部をミシン目カッターによりミシン目として形成するとよい。また、同製造方法において、前記溶融加工機は、前記張出部にヒーターを当接させて溶融させることにより前記溶融加工部を形成するとよい。この製造方法に用いられる包装袋は、袋開口部には風が吹き込まれて前記袋本体部が拡張し、内容物が前記袋本体部に挿入されるものである。 In the same manufacturing method, the easily cut portion may be formed as a perforation by a perforation cutter. Further, in the same manufacturing method, the melting processing machine may form the melting processing portion by bringing a heater into contact with the overhanging portion to melt the melting processing portion. In the packaging bag used in this manufacturing method, wind is blown into the bag opening to expand the bag main body, and the contents are inserted into the bag main body.

また、青果物用包装袋を用いた青果物包装方法の特徴は、包装装置と青果物用包装袋とを備え、袋本体部と、この袋本体部の袋開口部の片側から張り出す張出体とを有し、この張出体を前記袋開口部に沿って横断する易切断加工部を設けることで、この張出体を前記袋本体部側の張出部と包装機に取り付けられる耳部とに区切ってある青果物用包装袋を用いる方法であって、前記張出部には前記易切断加工部に沿って前記袋開口部と前記易切断加工部との間に溶融加工部を設けておき、前記包装装置は下部に向かうに従い順次窄まる円筒形状を呈し、下部では作業者側部分に近接する側に送風側部分が傾斜するホッパーを有し、前記溶融加工部の設けられた前記青果物用包装袋を前記耳部で複数積層して前記送風側部分の湾曲に前記耳部を沿わせて取り付け、前記袋開口部に風を吹き込んで前記袋本体部を拡張させ、開口された前記袋開口部から前記袋本体部に青果物を投入すると共に前記易切断加工部に沿って前記青果物の挿入された前記袋本体部を前記張出部と共に前記青果物の重さで切断し離脱させることにある。 In addition, the feature of the fruit and vegetable packaging method using the fruit and vegetable packaging bag is that it is equipped with a packaging device and a fruit and vegetable packaging bag, and has a bag main body and an overhanging body protruding from one side of the bag opening of the bag main body. By providing an easily cut processing portion that crosses the overhanging body along the opening of the bag, the overhanging body can be attached to the overhanging portion on the bag main body side and the ear portion attached to the packaging machine.

次に、図1~10を参照しながら、本発明の実施形態をさらに詳しく説明する。
本発明に係る青果物包装装置1は、図2,4に示すように、上部21から投入される青果物Vを下部22に取り付けられた包装袋10へ誘導するホッパー2と、ホッパー2の下部22へ向けて気体としての風(気流、空気)を送る送風部3とを備える。送風部3は装置本体部4と内部で連通し、装置本体部4に内蔵された送風手段5によって吸気口6から取り込んだ風が供給送風される。また、送風部3の下方には、包装袋10をホッパー2の下端近傍でホッパー2へ向けて押圧する支持具40が設けられている。
Next, an embodiment of the present invention will be described in more detail with reference to FIGS. 1 to 10.
As shown in FIGS. It is provided with a blower unit 3 for sending wind (air flow, air) as a gas toward the air. The air blowing unit 3 communicates with the device main body 4 internally, and the air taken in from the intake port 6 is supplied and blown by the air blowing means 5 built in the device main body 4. Further, below the blower portion 3, a support tool 40 for pressing the packaging bag 10 toward the hopper 2 near the lower end of the hopper 2 is provided.

本実施形態において、投入される青果物Vとしては、例えば、ニラ、青ネギや白ネギ等の長尺の青果物や、ほうれん草、青梗菜などの葉物が挙げられる。係る場合、青果物包装装置1は、例えば三脚100A等によって所定高さに設置されるほか、固定板7を利用してテーブル等に取り付けられる。 In the present embodiment, examples of the fruits and vegetables V to be introduced include long fruits and vegetables such as garlic chives, green onions and white onions, and leaves such as spinach and bok choy. In such a case, the fruit and vegetable packaging device 1 is installed at a predetermined height by, for example, a tripod 100A or the like, and is attached to a table or the like by using a fixing plate 7.

包装袋10は、図3に示すように、袋開口部12から突出する張出体13と、本実施形態では、短冊状の第一フィルム17及び第二フィルム18をその周縁部で溶着して袋状に形成している。また、第一フィルム17を第二フィルム18よりも長く形成することで、第一フィルム17に袋開口部12より突出する張出体13を一体に形成する。張出体13には、ホッパー2の取付ピン25に貫通させる一対の貫通孔14と、袋開口部12近傍に易切断部としてのミシン目15が形成されている。なお、第一、第二フィルム17,18の材質は特に限定されるものではないが、本実施形態では、例えば二軸延伸ポリプロピレンフィルムを用いる。 As shown in FIG. 3, the packaging bag 10 is formed by welding the overhanging body 13 protruding from the bag opening 12 and the strip-shaped first film 17 and the second film 18 at the peripheral portions thereof in the present embodiment. It is formed in a bag shape. Further, by forming the first film 17 longer than the second film 18, the overhanging body 13 protruding from the bag opening 12 is integrally formed with the first film 17. The overhanging body 13 is formed with a pair of through holes 14 to penetrate through the mounting pin 25 of the hopper 2 and a perforation 15 as an easy-to-cut portion in the vicinity of the bag opening 12. The materials of the first and second films 17 and 18 are not particularly limited, but in the present embodiment, for example, a biaxially stretched polypropylene film is used.

各包装袋10は複数枚が張出体13の耳部13bで融着されて、包装袋束10xを形成する。装袋束10xは、ミシン目15で袋がちぎれると、張出体13の耳部13bは積層して残る。ミシン目(易切断加工部)15と袋開口部12との間には後述の溶融加工部16が設けられている。この溶融加工部16により、ミシン目15を起点とする引き裂きはストップされ、張出部13aが耳部13bから裂けることなく離脱する。したがって、ミシン目15を基点とする引き裂きが連続することを防止するために、溶融加工部16は袋開口部12よりもミシン目15により近いことが望まれる。 A plurality of each packaging bag 10 is fused at the selvage portion 13b of the overhanging body 13 to form a packaging bag bundle 10x. In the bag bundle 10x, when the bag is torn off at the perforation 15, the selvage portion 13b of the overhanging body 13 remains laminated. A melt processing portion 16 described later is provided between the perforation (easy cutting processing portion) 15 and the bag opening portion 12. The melt-processed portion 16 stops the tearing starting from the perforation 15, and the overhanging portion 13a separates from the selvage portion 13b without tearing. Therefore, in order to prevent continuous tearing from the perforation 15 as a base point, it is desired that the melt-processed portion 16 is closer to the perforation 15 than the bag opening 12.

ここで、図6と図3とを対照しながら、製袋機100の構造と工程について説明する。製袋機100の構造には、まず、第一、第二フィルム17,18がロール状体で供給され、ローラーR1で付き合わされる。上述の張出体13部分が第一フィルムだけが例えば図6手前側にずらされて形成される。第一、第二フィルム17,18が付き合わされた状態で後端シール切断機101に入り、第一、第二フィルム17,18ともに溶断され、包装袋の下端が連続的に形成される。ミシン目形成機102は、間欠的に刃が円周部に形成されたカッターと、下部のバックアップローラーよりなり、張出体13にミシン目(易切断加工部)15を連続形成する。続いて、抜きプレス機103により一対の貫通孔14を形成する。 Here, the structure and process of the bag making machine 100 will be described with reference to FIGS. 6 and 3. In the structure of the bag making machine 100, first, the first and second films 17 and 18 are supplied in a roll form and are associated with each other by the roller R1. The above-mentioned overhanging body 13 portion is formed by shifting only the first film to, for example, the front side of FIG. The first and second films 17 and 18 are joined to the rear end seal cutting machine 101, and both the first and second films 17 and 18 are fused to continuously form the lower end of the packaging bag. The perforation forming machine 102 includes a cutter whose blade is intermittently formed on the circumferential portion and a backup roller at the lower portion, and continuously forms perforations (easy cutting processing portions) 15 on the overhanging body 13. Subsequently, a pair of through holes 14 are formed by the punching press 103.

そして、溶融加工機104により上述の溶融加工部16をミシン目(易切断加工部)15と袋開口部12との間に形成する。その後、サイドシール切断機105により,第一、第二フィルム17,18の突き合わせ体が溶断されるとともに、サイドシールがなされて包装袋10が形成され、コンベア106でスタッカー107に運ばれて積層される。積層された包装袋10の束は適宜枚数毎に上述の耳部13bで貼り合わされる。なお、包装袋10の束を形成せずに個別の包装袋を包装装置にセットしてもよいが、束のほうが包装袋10の交換が容易である。
Then, the above-mentioned melting processing portion 16 is formed between the perforation (easy cutting processing portion) 15 and the bag opening 12 by the melting processing machine 104. After that, the butted bodies of the first and second films 17 and 18 are melted by the side seal cutting machine 105, and the side seals are made to form the packaging bag 10, which is carried to the stacker 107 by the conveyor 106 and laminated. To. The bundles of the laminated packaging bags 10 are appropriately bonded to each other at the selvage portion 13b described above. Although individual packaging bags may be set in the packaging device without forming a bundle of packaging bags 10, the bundles are easier to replace the packaging bags 10.

図7は、溶融加工機104の断面図である。溶融加工機104は、シリンダーにより間欠的に上下するヒーター部110と、受け部120とを備えている。ヒーター部110は、ブロック111の下端にくさび形の溶融部112を取付け、ブロック111内に紙面前後に貫通形成した長孔に、シースヒーター等のヒーター113を挿入している。ボルト115で固定される熱電対114によりヒーター113の温度は管理され、第一フィルム17が溶断されずに溶融されて、フィルムの引き裂きをストップさせる溶融加工部16を形成できるようになっている。 FIG. 7 is a cross-sectional view of the melting machine 104. The melting machine 104 includes a heater portion 110 that is intermittently moved up and down by a cylinder, and a receiving portion 120. The heater portion 110 has a wedge-shaped melting portion 112 attached to the lower end of the block 111, and a heater 113 such as a sheath heater is inserted into a long hole formed through the block 111 in front of and behind the paper surface. The temperature of the heater 113 is controlled by the thermocouple 114 fixed by the bolt 115, and the first film 17 is melted without being melted so that the melt-processed portion 16 that stops the tearing of the film can be formed.

なお、溶融加工機104のヒーター部110は、ローラー状のヒーターや超音波シール機を用いて連続加工することも可能である。しかし、幅方向に圧力を分散させて、上述の機能を溶融加工させるには、上下動するヒーター部110の上下動する溶融加工機104が優れている。 The heater portion 110 of the melting processing machine 104 can be continuously processed by using a roller-shaped heater or an ultrasonic sealing machine. However, in order to disperse the pressure in the width direction and melt the above-mentioned functions, the melting machine 104 that moves up and down of the heater unit 110 that moves up and down is excellent.

製袋機100において、後端シール切断機101、ミシン目形成機102、抜きプレス機103、溶融加工機104は適宜前後させて設けても構わない。ただし、後端シール切断機101及びミシン目形成機102の後に溶融加工機104を配置することで、ミシン目15に溶融加工部16をより近接させるように微調整することが容易となる利点がある。 In the bag making machine 100, the rear end seal cutting machine 101, the perforation forming machine 102, the punching press machine 103, and the melting processing machine 104 may be provided back and forth as appropriate. However, by arranging the melting machine 104 after the rear end seal cutting machine 101 and the perforation forming machine 102, there is an advantage that it becomes easy to make fine adjustments so that the melting machine 16 is closer to the perforation 15. be.

送風部3は、図1,2に示すように、吸気口6から空気を取り込み送風手段5のブロア5aにより放出口31から空気Bを下部に向けて放出し、この放出口31と装置本体部4とを連通させる連通部32を備えている。送風手段5の調整器5bはブロア5aのモーター等と接続される可変抵抗器であり、ノブ5b1を回動させることにより抵抗値を変更させて、ブロア5aの送風量を調整する。連通部32の側面32aには、後述の固定手段24aを螺合させるねじ孔33が形成されている。また、送風部3には、鉛直方向Zに沿って垂下する板状の垂下部34が設けられている。 As shown in FIGS. 1 and 2, the blower portion 3 takes in air from the intake port 6 and discharges the air B from the discharge port 31 toward the lower part by the blower 5a of the blower means 5, and the discharge port 31 and the device main body portion. A communication unit 32 for communicating with 4 is provided. The regulator 5b of the blower means 5 is a variable resistor connected to the motor or the like of the blower 5a, and the resistance value is changed by rotating the knob 5b1 to adjust the blower amount of the blower 5a. A screw hole 33 for screwing the fixing means 24a, which will be described later, is formed on the side surface 32a of the communication portion 32. Further, the blower portion 3 is provided with a plate-shaped hanging portion 34 that hangs down along the vertical direction Z.

Both the neck 71c and the notch 72c prevent the flaps 71 and 72 from falling out of the slits 26 and 27.

ここで、図1~5を参照しながら青果物Vの包装工程について説明する。
まず、図4(a)に示すように、支持具40をホッパー2から離隔させた状態で、複数枚の包装袋束10xを張出体13の貫通孔14を介してホッパー2の取付ピン25にそれぞれ掛止させて取り付ける。この時、包装袋10は第一フィルム17によって鉛直方向Zに吊り下げられ、袋開口部12はホッパー2の下開口部の直下に位置する。ここで、包装袋10をホッパー2の外周面20のうち送風部側部分22aに密着して沿うように傾斜させて、図4(b)に示すように、支持具40をホッパー2側へ揺動させる。これにより、上支持体41がホッパー2の下部22で包装袋束10xの耳部13bの端に近い部分P,Pを、先の押圧部41a,41aを送風部側部分22aに押圧して保持する。P,P間の内側にもさらに押圧部を設けてもよい。
Here, the packaging process of fruits and vegetables V will be described with reference to FIGS. 1 to 5.
First, as shown in FIG. 4A, with the support 40 separated from the hopper 2, a plurality of packaging bag bundles 10x are placed through the through holes 14 of the overhanging body 13 and the mounting pins 25 of the hopper 2 are inserted. Attach to each of them by hanging them. At this time, the packaging bag 10 is suspended in the vertical direction Z by the first film 17, and the bag opening 12 is located directly below the lower opening of the hopper 2. Here, the packaging bag 10 is tilted so as to be in close contact with the blower portion side portion 22a of the outer peripheral surface 20 of the hopper 2, and the support 40 is rocked toward the hopper 2 as shown in FIG. 4 (b).

As a result, the upper support 41 holds the portions P and P near the end of the selvage portion 13b of the packaging bag bundle 10x at the lower portion 22 of the hopper 2 by pressing the previous pressing portions 41a and 41a against the blower portion side portion 22a. do. A pressing portion may be further provided inside between P and P.

次に、青果物包装装置1の電源を入れ、風Bを送風手段5のブロア5aにより送風部3へ供給し、放出口31からホッパー2の下部22へ向けて放出する。ホッパーの下部22、耳部13b,袋開口部12及びミシン目15の関係は図2,5(a)のようになる。通気切欠28を設け、しかも、通気路は、送風部3の放出口31から連続してホッパーの一部と共同して筒状空間を形成する幅広垂下部34aと、通気切欠28近傍以下に連続する幅狭垂下部34bとを備え、幅狭垂下部34bとホッパー2との間に横開口部34cを形成してあるため、図5(a)に示すように、風Bは袋開口部12に容易に吹き込み、包装袋10は斜めに傾斜して膨らむこととなる。 Next, the power of the fruit and vegetable packaging device 1 is turned on, the wind B is supplied to the blower portion 3 by the blower 5a of the blower means 5, and is discharged from the discharge port 31 toward the lower portion 22 of the hopper 2. The relationship between the lower portion 22 of the hopper, the selvage portion 13b, the bag opening portion 12, and the perforation portion 15 is as shown in FIGS. A ventilation notch 28 is provided, and the ventilation passage is continuous from the discharge port 31 of the air blower 3 to the wide hanging lower portion 34a which forms a tubular space jointly with a part of the hopper, and is continuous below the vicinity of the ventilation notch 28. Since the width narrowing lower portion 34b is provided and the lateral opening portion 34c is formed between the width narrowing lower portion 34b and the hopper 2, the wind B is the bag opening portion 12 as shown in FIG. 5 (a). The packaging bag 10 is slanted and inflated.

そして、図2,図4(b)に示すように、作業者が青果物Vをホッパー2の上部21から投入(落下)すると、青果物Vはホッパー2によって鉛直方向Zに誘導される。ホッパー2の下部22直下では、風Bにより袋開口部12が開口しており、先の両フラップ71,72で誘導されるので、青果物Vを包装袋10、スムースに充填することができる。そして、青果物Vの重さにより、包装袋10はミシン目15で切断されると共に風Bによって、次の包装袋10が開口される。このように、作業者はホッパー2の上部21から青果物Vを投入すれば、投入された青果物Vはほぼ自動的に包装袋10へ投入され、包装が完了する。 Then, as shown in FIGS. 2 and 4, when the worker throws (falls) the fruit and vegetable V from the upper portion 21 of the hopper 2, the fruit and vegetable V is guided in the vertical direction Z by the hopper 2. Immediately below the lower portion 22 of the hopper 2, the bag opening 12 is opened by the wind B and is guided by both flaps 71 and 72, so that the fruit and vegetable V can be smoothly filled in the packaging bag 10. Then, the packaging bag 10 is cut at the perforation 15 due to the weight of the fruits and vegetables V, and the next packaging bag 10 is opened by the wind B. In this way, if the worker throws the fruits and vegetables V from the upper portion 21 of the hopper 2, the put fruits and vegetables V are almost automatically put into the packaging bag 10 and the packaging is completed.
