Description
本発明は、黒緑豆もやし、緑豆もやし、大豆もやし、アルファルファもやし、その他各種の芽もの野菜、裁断野菜、その他の野菜類、麺類や菓子などの各種食品、各種惣菜などの包装品を所定量ずつ袋に開口部から充填し、袋の開口部をシールして包装する袋による包装方法及び包装装置に関する。 The present invention includes black mung bean sprout, mung bean sprout, soy bean sprout, alfalfa sprout, other various sprout vegetables, cut vegetables, other vegetables, various foods such as noodles and confectionery, and packaged products such as various side dishes. The present invention relates to a packaging method and a packaging apparatus using a bag that fills a bag from an opening and seals and seals the opening of the bag.
前記した各種の芽もの野菜、細断野菜、麺類や菓子などの各種の包装品が袋詰めされ、その開口部をシールして包装された形の商品として流通されるものが多くなっている。このような袋詰め商品に用いられる袋が厚手で自立性のあるものの場合は、その包装品充填袋の開口部をきれいにシールすることは容易であるが、その包装袋が薄手の場合は、袋の開口部は皺のない状態で自立し難いので、包装品を充填した袋の開口部を横方向にシールした場合に、シール部に皺が生ずる状態となって、皺のない綺麗な状態でシールがなされた袋詰め商品とすることが難しい。 Various types of packaged products such as the above-mentioned various bud vegetables, shredded vegetables, noodles and confectionery are packaged, and the products that are packaged in the form of being packaged with their openings sealed are increasing. When the bag used for such a bag-packed product is thick and self-supporting, it is easy to cleanly seal the opening of the package-filled bag, but when the packaging bag is thin, the bag Since the opening of the bag is difficult to stand on its own with no wrinkles, when the opening of the bag filled with the package is sealed in the lateral direction, wrinkles are generated in the sealed portion, and there is no wrinkle in a clean state. It is difficult to make a packaged product with a seal.
袋に充填される包装品の重量が軽い場合、その包装に使われる袋は薄手のものとなることが多いので、包装品を充填した後の袋の開口部を皺のない状態で綺麗にシールすることが難しい場合が多い。包装品を充填した袋の開口部をシールして形成されたシール部に皺を生成させずにシールするため、従来はシールする袋の開口内に２本の拡開口バーを挿入し、その２本の拡開口バーを互いに離間させることにより袋開部を横方向に平たく緊張された状態にしてシーラで挟んで加圧してシールすることが行われて来た（特許文献１）。しかしながら、拡開口バーには細くて可撓性を持つバーなどが使用されるため、拡開口バーは使用により損傷し易く、劣化によって折損するような事が起ると、その破損した部材が包装品に混入する恐れもあるため、常に点検を行うとともに定期的な交換を必要とするなど、メンテナンスに手数と費用を要する欠点があった。 If the weight of the package filled in the bag is light, the bag used for the package is often thin, so the bag opening after filling the package is neatly sealed without wrinkles. It is often difficult to do. In order to seal the sealing portion formed by sealing the opening portion of the bag filled with the packaged product without generating wrinkles, conventionally, two expanded-opening bars are inserted into the opening of the bag to be sealed. It has been practiced that the bag opening portion is flattened in the lateral direction by separating the open-opening bars of the book from each other so as to be pressed and sealed with a sealer (Patent Document 1). However, a thin and flexible bar or the like is used for the wide opening bar. Therefore, the wide opening bar is easily damaged by use, and if it breaks due to deterioration, the damaged member is wrapped. Since there is a possibility that it may be mixed into the product, there are disadvantages that require maintenance and labor, such as constant inspection and regular replacement.
また、包装品を充填した袋の開口部を回転するブラシ体で撫で上げて伸ばした状態にしてシーラで両側から挟んでシールする構成としたものが提案されたが、回転するブラシ体からブラシ材が折れて脱落すると、それら破断部材が包装品の充填された包装袋内に入ってしまう事態が懸念され、この構成のものを採用可能な包装品には自ずと制約があり、シール部における皺生成防止のためにこの方式の皺取り手段を食品包装に使用することは避けたい。
袋による従来の包装技術が上記した問題点を有していたのに鑑み、本発明は、上向きに開口している袋内に包装品を充填したのち、その開口部を皺生成のない状態でシールして密閉することを安定して行わせることができ、しかも、部品の損傷や磨耗に備えた煩雑なメンテナンスを必要とせずに、包装品充填袋の開口部をシール可能とした、袋による包装方法及び包装装置を提供することを課題としている。 Considering that the conventional packaging technology using bags has the above-mentioned problems, the present invention fills a packaged product in an upwardly opened bag, and then keeps the opening in a state without generating wrinkles. With a bag that can be sealed and sealed stably, and the opening of the packaged bag can be sealed without the need for complicated maintenance in preparation for damage or wear of parts. It is an object to provide a packaging method and a packaging apparatus.

Reference numeral 16 denotes a gas inlet pipe. A gas such as air supplied from an appropriate sirocco fan or the like is formed from the plastic film F by the bag making machine 1 through the input unit 10 and the middle cylinder 3 of the bag making machine 1. Into a cylindrical bag. The gas to be fed may be an appropriate gas depending on the type of the packaged product other than air, and the supply pressure and the air volume may be appropriately determined according to the thickness of the plastic film F forming the packaged product or the bag. As an example, in the case of a plastic bag with a film thickness of 25 μm, the supply pressure (maximum static pressure) was 450 Pa and the air volume was 5.0 m 3 / min.
図示した袋による包装装置は以上説明した構成を有しており、この装置による包装品の包装は次のように行われる。先ず、製袋機１ではフォーマー２によって丸められて中筒３の周りに導かれたプラスチックフィルムＦは、重ねられた両側の縁部分が縦シーラ４によって筒状体に成形され、中筒３の周りに沿って下方に送られる。このように製袋機１によって成形されたプラスチックフィルム製の筒状体の中には、計量機９によって計量された所定量のもやしなどの包装品が、ホッパー８、投入部１０、中筒３を経て供給される。併せて、プラスチックフィルム製の筒状体の中には投入部１０と中筒３を経てガス送入管１６からの空気が送入され、これによって、筒状体内の底部に所定量の包装品が安定的に充填される。 The illustrated bag packaging apparatus has the above-described configuration, and packaging of packages by this apparatus is performed as follows. First, in the bag making machine 1, the plastic film F rounded by the former 2 and guided around the inner cylinder 3 is formed into a cylindrical body by the vertical sealer 4 at the edge portions on both sides, and the inner cylinder 3 Sent down along the circumference. In the cylindrical body made of plastic film formed by the bag making machine 1 in this way, a predetermined amount of bean sprout such as sprouts weighed by the weighing machine 9 is contained in the hopper 8, the input unit 10, and the middle cylinder 3. Supplied via At the same time, air from the gas inlet pipe 16 is fed into the cylindrical body made of plastic film through the input section 10 and the middle cylinder 3, whereby a predetermined amount of packaged product is placed at the bottom of the cylindrical body. Is stably filled.
筒状体内に充填されるもやしなどの包装品は、短辺方向に沿って水平方向に往復して変位するように加振機１４によって加振されている細長い通路を形成されている加振用枠体１１を通過する際に、その長さ方向を加振用枠体１１の長辺に沿う方向に向けられて筒状体内に落下送入されるので、筒状体内には、もやしなどの包装品の長さ方向が、加振用枠体１１によって細長い扁平状態にされた筒状体が形成する袋のプラスチックフィルムＦの面に沿う方向、に向けられた状態になる。従って、このようにプラスチックフィルムＦの面に沿う方向になって筒状体が形成する袋内に充填されているもやしなどの包装品は、脱気板６によって両側から押圧されても、長さ方向に直角方向な方向に押されることとなり、内部の包装品が折れる割合が少ない。また、このように袋のプラスチックフィルムＦの面に沿う方向、に向けられた状態にして袋詰めされた包装品は、物流の過程で重ねられたり移送途中に振動を与えられても折れる割合が少なくて済む。 The packaged product such as bean sprouts filled in the cylindrical body is provided with an elongate passage that is vibrated by the shaker 14 so as to reciprocate in the horizontal direction along the short side direction. When passing through the frame body 11, the length direction thereof is directed in the direction along the long side of the vibration frame body 11 and dropped into the cylindrical body. The longitudinal direction of the packaged product is directed to the direction along the surface of the plastic film F of the bag formed by the cylindrical body that is elongated and flattened by the vibration frame 11. Therefore, even if the packaged product such as bean sprouts filled in the bag formed by the cylindrical body in the direction along the surface of the plastic film F is pressed from both sides by the deaeration plate 6, the length It will be pushed in the direction perpendicular to the direction, and the rate of breakage of the internal package will be small. In addition, a packaged product packed in a bag oriented in the direction along the surface of the plastic film F of the bag in this way has a ratio of being folded even if it is piled up in the course of physical distribution or given vibration during transfer. Less is enough.
包装品が内部に充填された筒状体は横シーラ及びカッター５の横シーラによって横シールされてカッターにより切り離されるが、包装品充填部分の上部が、横シーラ及びカッター５で横シールされて切り離される筒状体には、ガス送入管１６から送入されたガスが送り込まれ、筒状体は膨らまされた状態で加振用枠体１１を通って細長い扁平状態にされた上で、脱気板６で両側から押圧されて上方に送り出される内部のガスによって扁平状態に張られて伸ばされることになり、その状態で横シーラによって挟まれて横シールされるので、その横シール部は伸ばされて皺のない状態で形成される。このように、製袋機１の中筒３を通して空気などのガスを、袋を形成する筒状体内に常時供給する構成を採用することによって、袋の開口部を塞ぐ横シール部には皺を発生させることなく袋詰めした包装品を得ることができる。 The cylindrical body filled with the packaged product is laterally sealed by the horizontal sealer and the horizontal sealer of the cutter 5 and separated by the cutter, but the upper part of the packed product is laterally sealed by the horizontal sealer and the cutter 5 and separated. The gas fed from the gas feed pipe 16 is fed into the cylindrical body that is inflated and passed through the vibration frame 11 in an inflated state, and then removed. It is stretched in a flat state by an internal gas that is pressed from both sides by the air plate 6 and fed upward, and in this state, it is sandwiched by a lateral sealer and laterally sealed, so that the lateral seal portion is stretched It is formed without any wrinkles. In this way, by adopting a configuration in which a gas such as air is constantly supplied to the cylindrical body forming the bag through the middle cylinder 3 of the bag making machine 1, the lateral seal portion that closes the opening of the bag is padded. The packaged product can be obtained without generating it.
以上、本発明の容器による包装装置を図示した実施例に基づいて具体的に説明したが、本発明はこの実施例に限定されないことはいうまでもない。
例えば、図示した実施例では、製袋機１で成形される筒状体内にガスを送給して袋詰め包装する場合について説明したが、予め製造された袋の開口部を上方に向けて開口させて包装品を充填する場合であってもよく、その袋の開口部に適宜の手段でガスを送給しつつ袋開口部を横シールすることにより皺の生成ない横シールされた包装品を得ることができる。
また、図示した装置では、加振用枠体１１を採用して袋内に充填される包装品の長さ方向を袋の面に沿う方向に揃えた状態にして包装する場合について説明したが、包装品によっては、このような揃え操作は必要が無く、要は、包装品を充填した袋内に袋の開口部からガスを供給しつつ横シールするだけで皺のない横シールがなされた包装が行われるようにするだけの構成としてよい。
As mentioned above, although the packaging apparatus by the container of this invention was demonstrated concretely based on the illustrated example, it cannot be overemphasized that this invention is not limited to this Example.
For example, in the illustrated embodiment, the case where gas is fed into a cylindrical body formed by the bag making machine 1 to be packed in a bag has been described, but the opening of a bag manufactured in advance is opened upward. The package may be filled with a package, and a side-sealed package that does not generate wrinkles is formed by laterally sealing the bag opening while feeding gas to the bag opening by an appropriate means. Obtainable.
Further, in the illustrated apparatus, the case has been described in which the vibration frame 11 is used for packaging in a state where the length direction of the packaged product filled in the bag is aligned in the direction along the surface of the bag. Depending on the package, there is no need for such an aligning operation. In short, a package that has a horizontal seal with no wrinkles by simply performing a horizontal seal while supplying gas from the bag opening into the bag filled with the package. The configuration may be such that only is performed.
また、図示した実施例では、包装品を充填する袋内に送給するガスとして空気を採用しているが、包装品に応じて、品質劣化防止成分を有するガス、不活性ガス、殺菌作用のあるガスなど適宜のガスであってよい。また、図示した実施例では、包装品を充填した袋を脱気板６で挟んで脱気する場合について説明したが、包装品充填袋の脱気は上記した脱気板６による構成のものに限らず、他の適宜の脱気手段で両側から押圧して脱気する機構のものを採用してよく、包装品を充填した袋にガスを供給しつつ、両側から押圧して脱気し、その開口部を横シールし、作用するガス圧によってその横シール部に皺生成を起らないようにして包装することができる。 In the illustrated embodiment, air is used as the gas to be fed into the bag filled with the packaged product. However, depending on the packaged product, a gas having a quality deterioration preventing component, an inert gas, and a sterilizing action. An appropriate gas such as a certain gas may be used. In the illustrated embodiment, the case where the bag filled with the packaged product is deaerated by being sandwiched by the degassing plate 6 is described. However, the degassing of the packaged product filled bag is performed by the above-described degassing plate 6. Not limited to this, a mechanism that degass by pressing from both sides with other appropriate degassing means may be adopted, while degassing by pressing from both sides while supplying gas to the bag filled with the packaged product, The opening can be laterally sealed and packaged in such a manner that no soot formation occurs in the lateral seal due to the acting gas pressure.
また、図示した実施例では、包装品に対して横断面が細長くて扁平な包装品投入通路を与えるための加振用枠体１１に対して、その短辺に沿う方向に往復運動を与えるため、加振機１４によって水平方向の振動を与えているが、水平方向に限らず、円運動など、水平方向成分を持つ往復動を与えるものであってよい。 Further, in the illustrated embodiment, the vibration frame 11 for providing a package input passage having a long and narrow cross section with respect to the package product is provided with a reciprocating motion in the direction along the short side thereof. Although the vibration in the horizontal direction is given by the vibration exciter 14, the vibration is not limited to the horizontal direction, and a reciprocating motion having a horizontal direction component such as a circular motion may be given.
