Description
本発明は液体食品を充填する紙容器の紙粉除去に関し、詳しくは帯状の包材を用いて液体食品を連続充填して紙容器を製造する紙容器充填装置に設ける紙粉除去方法とその紙粉除去方法を用いた紙粉除去装置に関する。 The present invention relates to removing paper dust from a paper container filled with liquid food, and more specifically, to a paper dust removing method provided in a paper container filling apparatus for continuously filling liquid food using a band-shaped packaging material to produce a paper container and the paper The present invention relates to a paper dust removing device using a powder removing method.
従来、ジュース、牛乳等の液体食品などを充填する紙容器充填装置の紙粉除去装置に関する従来技術として特許文献１の内容が知られている。特許文献１によれば、充填機において帯状の包材を用いて、長手方向に縦シール部を形成して成るチューブ状包材に内容液を充填し所定間隔毎に横シール部で密封且つ切断して紙容器が形成される。ところが、包材が帯電すると静電気力によって紙粉の付着力が大きくなるので紙粉を除去するのが困難であるという問題があった。 Conventionally, the content of patent document 1 is known as a prior art regarding the paper dust removal apparatus of the paper container filling apparatus filled with liquid foods, such as juice and milk. According to Patent Document 1, a strip-shaped packaging material is used in a filling machine to fill a tube-shaped packaging material formed by forming a longitudinal seal portion in the longitudinal direction, and sealed and cut by a lateral seal portion at predetermined intervals. Thus, a paper container is formed. However, when the packaging material is charged, there is a problem that it is difficult to remove the paper dust because the adhesive force of the paper dust is increased by the electrostatic force.
そこで、図７に示すように、紙粉除去装置２１は包材２２の表側及び裏側を除電する除電装置２３、２４と、除電した紙粉を除去する集塵装置２５とで構成され、集塵装置２５には集塵ノズル２６を備える。除電装置２３、２４は直流型のイオナイザの場合、図示しない正電極針及び負電極針から成る放電針と、各放電針に高電圧を印加するための高圧電源を備え、高電圧が印加されて放電針から放出されたイオンが包材２２に照射される。これによって包材２２の除電が行われるので静電気力が小さくなり紙粉の付着力が減少するので集塵効果が向上する。 Therefore, as shown in FIG. 7, the paper dust removing device 21 is composed of static eliminating devices 23 and 24 that neutralize the front and back sides of the packaging material 22, and a dust collecting device 25 that removes the neutralized paper dust. The device 25 includes a dust collection nozzle 26. In the case of a DC type ionizer, the static eliminators 23 and 24 are provided with a discharge needle composed of a positive electrode needle and a negative electrode needle (not shown), and a high voltage power source for applying a high voltage to each discharge needle. The packaging material 22 is irradiated with ions released from the discharge needle. As a result, the packaging material 22 is neutralized, the electrostatic force is reduced, and the adhesion of paper dust is reduced, thereby improving the dust collection effect.
ところが、包材２２の端部２２ａに付着した紙粉を除電によって確実に除去するのは難しく、クリーンチャンバーや成型用ガイドローラーが紙粉汚染して稀であるが紙容器内部に紙粉が混入する可能性があった。このため、目視やサンプリング等による紙粉混入検査を実施すると費用が嵩むので紙容器の製造コストが高くなるという問題があった。 However, it is difficult to reliably remove the paper dust adhering to the end 22a of the packaging material 22 by static elimination, and the clean chamber and the molding guide roller are rarely contaminated with paper dust, but paper dust is mixed inside the paper container. There was a possibility. For this reason, if paper dust mixing inspection by visual inspection or sampling is carried out, there is a problem that the cost increases, and the manufacturing cost of the paper container increases.
そこで、本発明は、従来の紙容器充填装置に設ける紙粉除去装置の問題点を解決して、紙容器への紙粉混入を確実に防止し、紙容器の製造コストを低減することができる紙粉除去方法と紙粉除去装置を提供することを目的とする。 Therefore, the present invention solves the problems of the paper dust removing device provided in the conventional paper container filling device, reliably prevents the paper dust from being mixed into the paper container, and can reduce the manufacturing cost of the paper container. An object is to provide a paper dust removing method and a paper dust removing device.
請求項１の発明は、熱可塑性樹脂を両面に備える帯状紙基材を縦シール部で筒状にして内容液を充填し、横シール部でシール且つ切断して枕状の原型容器を連続形成し、この原型容器の二対のフラップ部を折込み熱圧着で頂面と底面を形成して成る紙容器成形用の紙基材の紙粉除去方法である。そして、この紙粉除去方法は前記帯状紙基材の両端部に付着する紙粉を燃焼する燃焼手段と燃焼した残渣物を収集する収集手段とから成ることを特徴としている。 According to the first aspect of the present invention, a strip-shaped paper base material provided with a thermoplastic resin on both sides is formed into a cylindrical shape at a vertical seal portion, filled with a content liquid, and sealed and cut at a horizontal seal portion to continuously form a pillow-shaped prototype container. In this method, paper powder is removed from the paper base material for forming a paper container, in which two pairs of flap portions of the original container are folded and a top surface and a bottom surface are formed by thermocompression bonding. The paper dust removing method is characterized by comprising combustion means for burning the paper dust adhering to both ends of the belt-like paper base material and collecting means for collecting the burned residue.
請求項２の発明は、請求項１に記載の紙粉除去方法であって、前記燃焼手段は火炎式で前記収集手段はバキューム式であることを特徴としている。 A second aspect of the present invention is the paper dust removing method according to the first aspect, wherein the combustion means is a flame type and the collecting means is a vacuum type.
請求項３の発明は、請求項１又は請求項２に記載の紙粉除去方法で用いられる紙粉除去装置であって、前記紙粉除去装置は親ロールを裁断して複数の前記帯状紙基材を形成する裁断工程で前記帯状紙基材の両端部に備えることを特徴としている。 Invention of Claim 3 is a paper dust removal apparatus used with the paper dust removal method of Claim 1 or Claim 2, Comprising: The said paper dust removal apparatus cuts a parent roll, and is a plurality of said strip-shaped paper bases. It is characterized in that it is provided at both ends of the belt-like paper base material in a cutting step of forming a material.
請求項１の発明によれば、熱可塑性樹脂を両面に備える帯状紙基材を縦シール部で筒状にして内容液を充填し、横シール部でシール且つ切断して枕状の原型容器を連続形成し、この原型容器の二対のフラップ部を折込み熱圧着で頂面と底面を形成して成る紙容器成形用の紙基材の紙粉除去方法である。そして、この紙粉除去方法は前記帯状紙基材の両端部に付着する紙粉を燃焼する燃焼手段と燃焼した残渣物を収集する収集手段とから成る。このため、燃焼手段によって前記帯状紙基材の両端部を燃焼することで両端部に付着する紙粉を容易に燃焼し、収集手段によって燃焼した残渣物を確実に収集することができるので、紙容器内に紙粉が混入するのを確実に防止することができる。 According to the first aspect of the present invention, a strip-shaped paper base material provided with thermoplastic resin on both sides is formed into a cylindrical shape at the vertical seal portion, filled with the content liquid, sealed and cut at the horizontal seal portion, and a pillow-shaped prototype container is obtained. This is a method for removing paper dust from a paper base material for forming a paper container, which is formed continuously and folded into two pairs of flap portions of the original container to form a top surface and a bottom surface by thermocompression bonding. This paper dust removing method comprises a combustion means for burning paper dust adhering to both ends of the belt-like paper base material and a collecting means for collecting the burned residue. For this reason, it is possible to easily burn the paper powder adhering to both ends by burning both ends of the belt-like paper base material by the combustion means, and to reliably collect the residue burned by the collecting means. It is possible to reliably prevent paper dust from being mixed into the container.
目視やサンプリング等による紙粉混入検査を実施する必要がないので作業が簡素化するので、紙容器の歩留りが向上すると同時に紙容器の製造コストを低減できる。 Since it is not necessary to carry out a paper dust mixing inspection by visual inspection or sampling, the operation is simplified, so that the yield of paper containers can be improved and the manufacturing cost of paper containers can be reduced.
請求項２の発明によれば、前記燃焼手段は火炎式であるので、前記帯状紙基材の両端部の紙粉を非接触で燃焼する簡単な構造なので両端部を損傷することが無く製作コストも安価である。そして、燃焼した紙粉が前記紙粉収集手段のバキューム力により非接触で確実に収集できる。このため、請求項１の効果と同様の効果をさらに確実に得ることができる。 According to the invention of claim 2, since the combustion means is a flame type, since it is a simple structure that burns paper dust at both ends of the belt-like paper base material in a non-contact manner, both ends are not damaged and the production cost is reduced. Is also cheap. The burned paper dust can be reliably collected in a non-contact manner by the vacuum force of the paper dust collecting means. For this reason, the effect similar to the effect of Claim 1 can be acquired more reliably.
請求項３の発明によれば、前記紙粉除去装置は親ロールを裁断して複数の前記帯状紙基材を形成する裁断工程で前記帯状紙基材の両端部に備え、この裁断工程で紙粉発生と同時に紙粉を非接触で除去できるので紙粉の除去効果に優れ紙粉を確実に除去することができる。 According to the invention of claim 3, the paper dust removing device is provided at both ends of the belt-like paper substrate in a cutting step of cutting a parent roll to form a plurality of the belt-like paper substrates. Since the paper dust can be removed in a non-contact manner at the same time as the generation of the powder, it is excellent in the effect of removing the paper dust and can be reliably removed.
以下に、本発明の実施形態を図１〜図６に基づいて説明する。
＜紙粉除去装置の構成＞
Embodiments of the present invention will be described below with reference to FIGS.
<Configuration of paper dust removal device>
図１、図２、図３に示すように、紙容器成形装置１において、紙基材２に熱可塑性材料層３とバリヤー層４を備える帯状の包材５が図示しない繰出機から連続的に繰出される。帯状の包材５は図示しない複数のガイドローラーに案内され、上方から下方に下降しながら両端部６を矢印Ａに示すように寄せ重ねて熱圧着により縦シール７をして筒状に形成される。そして、この筒状部８に充填パイプ９を介して内容液９ａが連続的に充填される。なお、この紙容器成形装置１は図示しないクリーンチャンバー内に設置されている。 As shown in FIGS. 1, 2, and 3, in the paper container forming apparatus 1, a strip-shaped wrapping material 5 including a thermoplastic material layer 3 and a barrier layer 4 on a paper base 2 is continuously fed from a feeder (not shown). It is paid out. The belt-like wrapping material 5 is guided by a plurality of guide rollers (not shown), and is formed into a cylindrical shape by vertically sticking both end portions 6 as indicated by an arrow A while descending from the upper side and by vertical compression 7 by thermocompression bonding. The The cylindrical portion 8 is continuously filled with the content liquid 9a through the filling pipe 9. The paper container forming apparatus 1 is installed in a clean chamber (not shown).
筒状部８は紙容器一個分に相当する位置において遂次横シール１０で密封し且つ切断すると連続的に枕状の原型容器１１が形成される。そして、原型容器１１の一対のフラップ部１１ａと一対のフラップ部１１ｂを折込み熱圧着で頂面１２ａと底面１２ｂを形成し、他の四組の側面１２ｃと共に外形直方体形状の紙容器１２が形成される。なお、筒状部８の縦シール７における内側端部は図示しないストリップテープで覆われるので内容液９ａに触れることはない。 When the cylindrical portion 8 is successively sealed with a horizontal seal 10 and cut at a position corresponding to one paper container, a pillow-shaped prototype container 11 is continuously formed. Then, a pair of flap portions 11a and a pair of flap portions 11b of the original container 11 are folded to form a top surface 12a and a bottom surface 12b by thermocompression bonding, and a paper container 12 having a rectangular parallelepiped shape is formed together with the other four sets of side surfaces 12c. The In addition, since the inner side edge part in the vertical seal | sticker 7 of the cylindrical part 8 is covered with the strip tape which is not shown in figure, it does not touch the content liquid 9a.
帯状の包材５における一個分の紙容器１２を形成する領域Ｐには縦方向、横方向、斜め方向に折り目５ａ、５ｂ、５ｃが各々複数形成されているので、この折り目を折込むことで矩形の頂面１２ａと底面１２ｂと四組の側面１２ｃから成る直方体形状の紙容器１２が容易に形成される。 A plurality of folds 5a, 5b, and 5c are formed in the vertical direction, the horizontal direction, and the diagonal direction in the region P in the belt-shaped packaging material 5 in which the paper container 12 for one piece is formed. A rectangular parallelepiped paper container 12 including a rectangular top surface 12a, bottom surface 12b, and four sets of side surfaces 12c is easily formed.
図４に示すように、帯状の包材５は幅広の親包材１６を裁断して形成される。裁断装置１５の図示しない繰出機に取付けたロール状の親包材１６を繰出しながら４組の回転刃１７で裁断して所定幅Ｑの帯状の包材５を三組リール状に形成する。親包材１６の両端部１６ａは不要なので切り離し除去される。そして、各帯状の包材５の両端部に、裁断時に発生した紙粉を燃焼する燃焼手段１８と、その下流側に紙粉を収集する収集手段１９とから成る紙粉除去装置２０が設けられる。なお、図において紙粉除去装置２０は一組だけ示し、その他は図示されない。 As shown in FIG. 4, the band-shaped packaging material 5 is formed by cutting a wide parent packaging material 16. The roll-shaped parent wrapping material 16 attached to a feeding machine (not shown) of the cutting device 15 is cut by the four sets of rotary blades 17 while being fed to form the strip-shaped wrapping material 5 having a predetermined width Q in a three-reel shape. Since both end portions 16a of the parent packaging material 16 are unnecessary, they are separated and removed. A paper dust removing device 20 comprising a combustion means 18 for burning paper dust generated at the time of cutting and a collecting means 19 for collecting the paper powder is provided at both ends of each band-shaped packaging material 5. . In the figure, only one set of paper dust removing device 20 is shown, and the others are not shown.
図５、図６に示すように、帯状の包材５の詳細構成は、紙基材２に熱可塑性材料層３（３ａ、３ｂ、３ｃ、３ｄ）とバリヤー層４を備えて形成され、外側から内側に向かって外側層３ａ、紙基材２、接着層３ｂ、バリヤー層４、二層の内側層３ｃ、３ｄから成り、紙基材２の外側面にデザイン等２ａが予め印刷される。外側層３ａ、内側層３ｄは低密度ポリエチレン樹脂、内側層３ｃはポリエチレン或いはエチレン共重合体等の樹脂、バリヤー層４はアルミ箔等で形成される。 As shown in FIGS. 5 and 6, the detailed configuration of the band-shaped packaging material 5 is formed by providing the paper base material 2 with the thermoplastic material layer 3 (3 a, 3 b, 3 c, 3 d) and the barrier layer 4. The inner layer 3a, the paper substrate 2, the adhesive layer 3b, the barrier layer 4, and the two inner layers 3c and 3d are printed in advance on the outer surface of the paper substrate 2 in advance. The outer layer 3a and the inner layer 3d are formed of a low density polyethylene resin, the inner layer 3c is formed of a resin such as polyethylene or an ethylene copolymer, and the barrier layer 4 is formed of an aluminum foil or the like.
このため、親包材１６から所定幅Ｑに裁断して形成された帯状の包材５に発生する粉紙には、熱可塑性材料層３であるポリエチレン等の樹脂粉、バリヤー層４のアルミニウム等の箔粉が含まれる。 For this reason, the powder paper generated on the band-shaped packaging material 5 formed by cutting the parent packaging material 16 to a predetermined width Q includes resin powder such as polyethylene as the thermoplastic material layer 3, aluminum of the barrier layer 4, etc. Of foil powder.
ガス管１８ａを介して送られた燃焼手段１８のバーナーの炎１８ｂは帯状の包材５の端部６である端面Ｔとその近傍の両面Ｓを覆って燃焼するので、回転刃１７で切断した際に発生し付着している紙粉を容易且つ確実に燃焼することができる。なお、紙基材５の繰出される速度とバーナーの炎１８ｂの燃焼量との関係は、紙基材５に付着する紙粉は焦げるが紙基材５には影響を与えない状態に設定される。そして、燃焼した紙粉は収集手段１９の吸引流１９ｂに運ばれて吸引管１９ａで確実に排出される。
＜紙粉除去装置の作用＞
The burner flame 18b of the combustion means 18 sent through the gas pipe 18a burns while covering the end surface T, which is the end portion 6 of the strip-shaped wrapping material 5, and the both surfaces S in the vicinity thereof, and thus is cut by the rotary blade 17. It is possible to easily and reliably burn the paper dust generated and adhered. The relationship between the feeding speed of the paper base 5 and the amount of combustion of the burner flame 18b is set so that the paper dust adhering to the paper base 5 is burned but does not affect the paper base 5. The The burned paper dust is conveyed to the suction flow 19b of the collecting means 19 and is surely discharged by the suction pipe 19a.
<Operation of paper dust removing device>
燃焼手段１８のバーナーの炎１８ｂで紙基材５の端部６である端面Ｔ及びその近傍の両面Ｓを直接炙るので、熱によって活性化した紙粉は確実に燃焼すると同時に燃焼後の焦げた残渣物は炎１８ｂの風圧によって容易に離反して吹飛ばされ、燃焼手段１８の下流直後に備えるバキューム式の収集手段１９の吸引管１９ａを介して確実且つ容易に排出することができる。燃焼手段１８と収集手段１９は紙基材５に直接接触しないので端部６に物理的な影響を与えることなく焦げた紙粉を効率良く除去できる。 The end face T, which is the end portion 6 of the paper base material 5, and the both sides S in the vicinity thereof are directly blown by the burner flame 18b of the combustion means 18, so that the paper powder activated by heat burns reliably and at the same time is burnt after burning. The residue is easily separated and blown away by the wind pressure of the flame 18b, and can be reliably and easily discharged through the suction pipe 19a of the vacuum type collecting means 19 provided immediately after the combustion means 18. Since the burning means 18 and the collecting means 19 do not directly contact the paper base material 5, the burnt paper powder can be efficiently removed without physically affecting the end portion 6.
紙容器１２は紙粉の影響による接着不良が発生しないので容器としての成形性が向上する。紙粉が紙容器１２に混入する恐れがなくなる。紙粉の清掃不足等による人為的トラブルも減少するので、充填装置の稼働率が向上して歩留りが良くなり紙容器のコストを低減することができる。作業員による紙粉の付着状態や混入状況等の監視を目視や抜取検査等によって行う必要がなくなるので作業が簡素化できる。 Since the paper container 12 does not have poor adhesion due to the influence of paper dust, the moldability as a container is improved. There is no risk of paper dust mixing into the paper container 12. Since human trouble due to insufficient cleaning of paper dust and the like is reduced, the operating rate of the filling device is improved, the yield is improved, and the cost of the paper container can be reduced. Since it is not necessary for a worker to monitor the adhesion state and mixing state of paper dust by visual inspection or sampling inspection, the operation can be simplified.
さらに、焦げた残渣物は色が黒色系に変化するので容易に識別できるため除去等の処理作業が容易に判断できるので、成型ローラーへの紙粉付着、クリーンルーム内の紙粉汚染を回避して紙容器内への紙粉の混入を確実に防止できる。 In addition, since the burnt residue changes color to black, it can be easily identified, so it is easy to determine the processing operations such as removal, avoiding paper dust adhering to the molding roller and paper dust contamination in the clean room. It is possible to reliably prevent paper dust from mixing into the paper container.
以上、本発明の実施例を図面に基づいて説明したが、具体的な構成はこの実施例に限られるものではなく本発明の要旨を逸脱しない範囲の設計変更等があっても本発明に含まれる。たとえば、収集手段１９の設置位置は燃焼手段１８から離れて帯状の紙基材５を巻き取る直前に設けても構わない。バキューム式の収集手段１９に空気圧で紙粉を吹き飛ばすノズルを補うと収集効果が更に上がる。紙粉除去装置２０は紙容器成形装置１に設置することもできる。燃焼手段１８の燃焼効果で紙基材５の両端部６に付着する紙粉の残渣物が低減できるので状況により収集手段１９を省略することもできる。さらに、燃焼手段１８と収集手段１９は、４側面と底面を形成して内容液を充填した後に頂面を形成する屋根型紙容器の紙基材に対しても適用できる。
なお、本発明は前記実施の形態に限定されるものではなく、本発明の趣旨に基づいて種々変形させることが可能であり、それらを本発明の範囲から排除するものではない。
The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is. For example, the installation position of the collecting means 19 may be provided immediately before winding the belt-shaped paper substrate 5 away from the combustion means 18. If the vacuum collecting means 19 is supplemented with a nozzle that blows off paper dust by air pressure, the collecting effect is further improved. The paper dust removing device 20 can also be installed in the paper container forming device 1. Because of the combustion effect of the combustion means 18, paper dust residue adhering to both ends 6 of the paper substrate 5 can be reduced, so that the collection means 19 can be omitted depending on the situation. Furthermore, the combustion means 18 and the collection means 19 can be applied to the paper base material of the roof-type paper container that forms the top surface after forming the four side surfaces and the bottom surface and filling the content liquid.
In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
この発明は、ジュース、牛乳などの飲料を包装容器で包装充填する製造に適用することができる。 The present invention can be applied to the production of packaging and filling beverages such as juice and milk in packaging containers.
