Description

本発明は、手提げ袋の製造方法に関する。さらに詳しくは、本発明は、長方形に折り畳んだ状態で保管することができ、使用時には長方形の底面を有する直方体形状の袋体部と、大きい重量に耐える手提げ部が形成されるプラスチックフィルム製の手提げ袋の製造方法に関する。   The present invention relates to a method for manufacturing a handbag. More specifically, the present invention is a plastic film handbag that can be stored in a folded state in a rectangular shape and has a rectangular parallelepiped-shaped bag body portion and a handbag portion that can withstand a large weight when used. It relates to the manufacturing method.

新聞、折り込み広告、雑誌、包装紙などの古紙の回収と再利用は、パルプ原木資源の節約と国内外の森林資源の温存につながる。また、古紙を回収し再利用することにより、固形廃棄物としての自治体によるゴミ収集と処理への負担を軽減することができる。古紙の利用は、パルプの代替として有意義であるのみならず、資源環境問題への寄与が大きい。このために、新聞販売店、自治体、町内会、PTAなどにより、各家庭からの新聞などの古紙の回収が積極的に進められている。
しかし、古紙の市場は需給バランスの変動が激しく、古紙の価格が低迷を続ける時代も訪れるので、回収袋も安価であることが極力求められる。一方、新聞と折り込み広告を合わせると半月分で5kg程度の重量となり、回収袋にもこの重量に耐えて運搬し得るだけの強度が要求される。さらに、回収される古紙の種類は各団体により異なり、例えば、新聞、折り込み広告と雑誌類とを分別し、紙ひもでしばって出すことに定めている自治体もある。回収された古紙は、古紙集荷段階において選別が行われるが、この工程は人手に頼らざるを得ず、古紙のコストアップの一因となり、以後の機械的処理や古紙パルプの品質への影響が大きい。各家庭においても、定められた分別方法にしたがって古紙を出すとともに、ワックス加工紙、感熱記録紙などの禁忌品の混入を絶対に避けなければならない。このために、新聞雑誌などの回収に用いる手提げ袋は、収納された古紙が識別できる程度の半透明性を有することが好ましい。
Collection and reuse of used paper such as newspapers, insert advertisements, magazines, and wrapping papers will save raw pulp resources and preserve forest resources at home and abroad. In addition, by collecting and reusing waste paper, it is possible to reduce the burden on garbage collection and disposal by local governments as solid waste. The use of waste paper is not only meaningful as a substitute for pulp, but also contributes greatly to resource environment problems. For this reason, newspapers, local governments, neighborhood associations, PTAs, etc. are actively collecting used paper such as newspapers from households.
However, since the used paper market is experiencing a volatile fluctuation in the supply and demand balance and the price of used paper continues to stagnate, it is required that the collection bags be inexpensive. On the other hand, when combined with newspapers and insert advertisements, the weight is about 5 kg in half a month, and the collection bag is required to have enough strength to withstand this weight. Furthermore, the type of used paper collected varies from group to group. For example, some local governments stipulate that newspapers, insert advertisements and magazines are separated and put out with paper strings. The recovered used paper is sorted at the used paper collection stage, but this process must be relied on manually, which contributes to the cost increase of the used paper and affects the subsequent mechanical processing and quality of the used paper pulp. large. In each household, waste paper must be taken out according to a specified separation method, and incompatible products such as wax-processed paper and heat-sensitive recording paper must be avoided. For this reason, it is preferable that the handbag used for collecting newspapers and the like has a translucency that allows the stored used paper to be identified.

本発明は、長方形に折り畳んだ状態で保管することができ、使用時には長方形の底面を有する直方体形状の袋体部と、大きい重量に耐える手提げ部が形成されるプラスチックフィルム製の手提げ袋の製造方法を提供することを目的としてなされたものである。   The present invention provides a method for producing a handbag made of a plastic film that can be stored in a folded state in a rectangular shape, and has a rectangular parallelepiped-shaped bag body portion having a rectangular bottom surface and a handbag portion that can withstand a large weight when used.

Next, the feeding of the belt-like film is switched to pitch transfer by a transfer means (not shown), and the film 4 is cut by the punching blade 5 and the punching receiving plate 6 for each width of the bag body at the side edge where the inner center fold is cut. A sheet is punched out to form a hand-held part. The weld receiving plate 7 is inserted between the gusset folds on both side edges, the substantially V-shaped heat welding blades 8 are pressed on both side ends of the boundary line between adjacent bags, and two gusset-folded films are used as side edges. It is welded in the form of a diagonal line. Finally, the band-shaped film is melted by pressing the hot fusing blade 9 for each width of the bag body to complete the handbag 10.

本発明方法においては、(1)ガゼット折りから(5)溶断までを2工程に分け、例えば、(1)両側縁に一対のW字形のガゼット折りを有する帯状フィルムを形成していったん巻き取り、あるいは、(1)両側縁に一対のW字形のガゼット折りを有する帯状フィルムを形成し、(2)一方のガゼット折りの内部中央の折り目を切断していったん巻き取り、以後の工程の原反フィルムとして用いることもできる。
本発明方法においては、(1)ガゼット折りが最初の工程、(5)溶断が最後の工程となるが、中間の(2)折り目の切断、(3)打ち抜き及び(4)溶着の各工程は、任意の順序に入れ替えることができる。本発明方法においては、(5)帯状フィルムを袋体の幅ごとに熱溶断刃を押し付けて溶断する工程の代わりに、(5')帯状フィルムを袋体の幅ごとに熱溶着刃を押し付けて2本の平行な熱溶着線で熱溶着し、次いで切断刃により2本の熱溶着線の間を切断することもできる。また、図1に示す態様においては、(4)溶着工程において、上側のフィルム2枚と下側のフィルム2枚をそれぞれ同時に熱溶着しているが、上側のフィルム2枚と下側のフィルム2枚の溶着を別々に分けて行うこともできる。
本発明方法において、内部中央の折り目を切断した方の側縁において、袋体の幅ごとにフィルム4枚を打ち抜く工程に用いる打抜刃の形状に特に制限はなく、例えば、図2に示す刃部分の側面形状が直線形である打抜刃、図3〜6に示す刃部分の側面形状が波形である打抜刃、図7に示す刃部分が間隔をおいて刃をつぶした点24を有する打抜刃などを挙げることができる。これらの中で、刃部分の側面形状が波形形状である打抜刃を用い、打抜刃が嵌入する凹形状を有する打抜受け板又は硬質弾性体からなる打抜受け板を使用することが好ましい。
In the method of the present invention, (1) from gusset folding to (5) fusing is divided into two steps. For example, (1) a band-shaped film having a pair of W-shaped gusset folds on both side edges is formed and wound up; Alternatively, (1) a band-shaped film having a pair of W-shaped gusset folds on both side edges is formed, and (2) a fold at the center of one gusset fold is cut and wound up once, and the raw film of the subsequent process Can also be used.
In the method of the present invention, (1) gusset folding is the first step, (5) fusing is the last step, but the intermediate (2) fold cutting, (3) punching and (4) welding steps are , Can be replaced in any order. In the method of the present invention, instead of the step of (5) pressing the hot film cutting blade for each width of the bag to melt the band film, (5 ′) pressing the hot film cutting blade for the width of the bag film. It is also possible to perform heat welding with two parallel heat welding wires and then cut between the two heat welding wires with a cutting blade. Further, in the embodiment shown in FIG. 1, in the (4) welding step, two upper films and two lower films are thermally welded at the same time, but two upper films and two lower films 2 are simultaneously welded. The welding of the sheets can also be performed separately.
In the method of the present invention, there is no particular limitation on the shape of the punching blade used in the step of punching four films for each width of the bag at the side edge of the inner center fold cut, for example, the blade shown in FIG. A punching blade whose side surface shape is linear, a punching blade whose side surface shape is corrugated as shown in FIGS. 3 to 6, and a point 24 where the blade portion shown in FIG. The punching blade etc. which have can be mentioned. Among these, it is possible to use a punching blade having a corrugated shape on the side surface of the blade portion and use a punching receiving plate having a concave shape into which the punching blade is fitted or a punching receiving plate made of a hard elastic body. preferable.

本発明方法において、打抜刃の刃部分の波形の側面形状に特に制限はなく、例えば、図3に示す鋸歯状、図4に示す三角形状、図5に示す大小の三角形が交互に配列した形状、図6に示す曲線形状などを挙げることができる。打抜刃の刃部分には、波形の先端から凹部にかけて刃付けがなされている。側面形状が波形の打抜刃でプラスチックフィルムを打ち抜くとき、まず波形の先端がフィルムと接触するので、フィルムが刃先から逃げることがない。そして、打抜刃が下降するにつれて、波形の先端から凹部にいたる傾斜部分の刃でフィルムを切断するので、フィルムは鋭利に切断され、糸引きなどを生ずることがなく、美麗に打ち抜くことができる。打抜刃の波形の先端間の間隔は、2〜20mmであることが好ましく、4〜10mmであることがより好ましい。波形の先端間の間隔が2mm未満であると、打ち抜きの際にフィルムに逃げを生ずるおそれがある。波形の先端間の間隔が20mmを超えると、打ち抜き部分の形状が不揃いになるおそれがある。
本発明方法に用いる打抜刃の材質に特に制限はなく、例えば、炭素工具鋼、合金工具鋼、ステンレス鋼、セラミックス、硬質樹脂成形品などを挙げることができる。本発明方法においては、打抜刃が金属製の打抜受け板と衝突することがないので、打抜刃に耐衝撃性は不要である。打抜刃の製造方法に特に制限はなく、例えば、薄い板金の端縁を機械的に研削して図3〜6に示すような刃付けをしたのち、打抜形状に曲げて台金に溶接し、打抜刃とすることができ、あるいは、塊状の鉄から中ぐり盤などを用いて刃先形状を削りだし、先端に刃付けをしたのち、焼き入れして硬化させ、メッキをして打抜刃を仕上ることができる。打抜刃を打抜機の台板に固定する方法に特に制限はなく、例えば、台板にネジで固定することができ、あるいは、台板に設けた溝に嵌合することができる。
In the method of the present invention, the shape of the corrugated side surface of the blade portion of the punching blade is not particularly limited. For example, the sawtooth shape shown in FIG. 3, the triangular shape shown in FIG. 4, and the large and small triangles shown in FIG. Examples thereof include a shape and a curved shape shown in FIG. The blade portion of the punching blade is bladed from the tip of the corrugation to the recess. When a plastic film is punched with a corrugated punching blade, the corrugated tip first comes into contact with the film, so that the film does not escape from the blade edge. Then, as the punching blade is lowered, the film is cut with the blade of the inclined portion from the leading end of the corrugation to the recess, so that the film is cut sharply and can be punched beautifully without causing stringing or the like. . The interval between the corrugated tips of the punching blade is preferably 2 to 20 mm, and more preferably 4 to 10 mm. If the distance between the tips of the corrugations is less than 2 mm, the film may escape during punching. If the interval between the tips of the corrugations exceeds 20 mm, the shape of the punched portion may become uneven.
There is no restriction | limiting in particular in the material of the punching blade used for this invention method, For example, carbon tool steel, alloy tool steel, stainless steel, ceramics, a hard resin molded product etc. can be mentioned. In the method of the present invention, since the punching blade does not collide with the metal punch receiving plate, the punching blade does not need impact resistance. There is no particular limitation on the manufacturing method of the punching blade. For example, after the edge of a thin sheet metal is mechanically ground and the blade is attached as shown in FIGS. 3 to 6, it is bent into a punching shape and welded to the base metal. It can be used as a punching blade, or the shape of the cutting edge is cut out from a lump of iron using a boring machine, and the tip is sharpened, hardened by hardening, plated and punched. The punching blade can be finished. There is no restriction | limiting in particular in the method of fixing a punching blade to the base plate of a punching machine, For example, it can fix to a base plate with a screw, or it can fit in the groove | channel provided in the base plate.

図8は、打抜刃が嵌入する凹形状を有する打抜受け板の一態様の部分断面図である。本態様においては、打抜受け板11上に硬質ゴム板12が敷かれ、上方から下降してくる打抜刃13が嵌入する溝14が凹形状として設けられている。上方から下降してくる打抜刃は、刃部分で積層されたフィルム15を切断して溝に嵌入し、刃先は打抜受け板とは接触しないので、打抜刃が打抜受け板に衝突する従来の打抜機に比べて発生する騒音がはるかに小さい。また、打抜刃の刃部分は、軟らかいプラスチックフィルムのみと接触するので、刃先の傷みが少なく、打抜刃は長寿命を保つ。さらに、打抜受け板上に硬質ゴム板を敷いておくことにより、打抜刃の刃先が万一打抜受け板と接触しても、大きな破損の発生を防ぐことができる。
図9は、硬質弾性体からなる打抜受け板の一態様の部分断面図である。本態様においては、硬質弾性体からなる打抜受け板16に上方から打抜刃13が下降し、硬質弾性体がわずかに弾性変形することにより、打抜受け板上の積層されたフィルム15が切断される。硬質弾性体と打抜刃との接触によっては、大きな騒音は発生しない。また、硬質弾性体の弾性変形量はわずかであるので、打抜刃の刃先の傷みが少なく、打抜刃は長寿命を保つ。使用する硬質弾性体に特に制限はなく、例えば、硬質ゴム、ポリカーボネート、ポリアミド、メタクリル樹脂、耐衝撃性ポリスチレン、ABS樹脂、硬質塩化ビニル、ポリエーテルエーテルケトン、ポリエーテルスルホン、ボリアミドイミド、軟鉄、超弾性合金などを挙げることができる。硬質弾性体からなる打抜受け板は、表面に荒れが生じた場合には交換が必要であるが、打抜刃の形状に対応して多種類の打抜受け板を作製する必要がなく、複数種の打抜刃に対して同一の打抜受け板を使用することができる。また、打抜刃と打抜受け板の厳密な位置合わせも不要である。
FIG. 8 is a partial cross-sectional view of one embodiment of a punching receiving plate having a concave shape into which a punching blade is fitted. In this embodiment, the hard rubber plate 12 is laid on the punch receiving plate 11, and the groove 14 into which the punching blade 13 descending from above is fitted is provided as a concave shape. The punching blade descending from above cuts the film 15 laminated at the blade portion and fits into the groove, and the cutting edge does not contact the punching receiving plate, so the punching blade collides with the punching receiving plate. Compared to conventional punching machines, the generated noise is much smaller. In addition, since the blade portion of the punching blade comes into contact with only the soft plastic film, there is little damage to the blade edge, and the punching blade maintains a long life. Furthermore, by placing a hard rubber plate on the punching receiving plate, even if the cutting edge of the punching blade comes into contact with the punching receiving plate, it is possible to prevent the occurrence of major damage.
FIG. 9 is a partial cross-sectional view of one embodiment of a punch receiving plate made of a hard elastic body. In this embodiment, the punching blade 13 descends from above on the punching receiving plate 16 made of a hard elastic body, and the hard elastic body is slightly elastically deformed, whereby the laminated film 15 on the punching receiving plate is formed. Disconnected. A large noise does not occur depending on the contact between the hard elastic body and the punching blade. Further, since the amount of elastic deformation of the hard elastic body is small, there is little damage to the cutting edge of the punching blade, and the punching blade maintains a long life. There are no particular restrictions on the hard elastic body used, for example, hard rubber, polycarbonate, polyamide, methacrylic resin, impact-resistant polystyrene, ABS resin, hard vinyl chloride, polyether ether ketone, polyether sulfone, polyamidoimide, soft iron, super elastic An alloy etc. can be mentioned. The punching receiving plate made of a hard elastic body needs to be replaced when the surface becomes rough, but it is not necessary to produce various types of punching receiving plates corresponding to the shape of the punching blade. The same punching receiving plate can be used for a plurality of types of punching blades. Further, it is not necessary to strictly align the punching blade and the punch receiving plate.

本発明方法において、打抜刃により打ち抜かれたフィルムの打抜屑は、空気輸送、機械的手段などにより帯状フィルム面から除去することができる。例えば、打抜刃を台金とともに筒状に形成して減圧ラインに接続し、フィルム4枚を打ち抜くと同時に、打抜刃の内部を減圧にして、フィルムの打抜屑を打抜刃の筒内に吸い込むことができ、あるいは、打抜受け板に圧縮空気吹き出し口を設け、打抜刃を台金とともに筒状に形成し、フィルム4枚を打ち抜くと同時に、圧縮空気吹き出し口から圧縮空気を吹き出し、フィルムの打抜屑を打抜刃の筒内に吹き飛ばすこともできる。また、打抜受け板の凹形状の内側に筒状の空間を形成し、フィルム4枚を打ち抜くと同時に該筒状の空間を減圧にし、フィルムの打抜屑を筒状の空間内に吸い込むことができ、フィルム4枚を打ち抜くと同時に台金とともに筒状に形成した打抜刃から圧縮空気を送って打抜屑を筒状の空間内に吹き飛ばすことができ、あるいは、打抜刃に付随して上下運動する突き棒を設け、フィルム4枚を打ち抜くと同時に突き棒を下降させて打抜屑を筒状の空間に突きこむこともできる。   In the method of the present invention, the punching scraps of the film punched by the punching blade can be removed from the belt-like film surface by pneumatic transportation, mechanical means or the like. For example, a punching blade is formed in a cylindrical shape together with a base metal and connected to a decompression line, and at the same time as punching four films, the inside of the punching blade is decompressed to remove punching scraps from the film. Can be sucked into, or provided with a compressed air outlet on the punching receiving plate, the punching blade is formed in a cylindrical shape together with the base metal, and at the same time the four films are punched out, the compressed air is discharged from the compressed air outlet. It is also possible to blow off blown film and punched film scraps into the cylinder of the punching blade. In addition, a cylindrical space is formed inside the concave shape of the punching receiving plate, and at the same time when four films are punched, the cylindrical space is depressurized and the punching waste of the film is sucked into the cylindrical space. The punching blade can be blown away into the cylindrical space by sending compressed air from the punching blade formed in a cylindrical shape with the base metal at the same time as the four films are punched, or attached to the punching blade. It is also possible to provide a thrust bar that moves up and down, punch the four films, and lower the thrust bar at the same time to thrust the punched waste into the cylindrical space.

下側の溶着線18が、帯状フィルムの側縁となす角度αは、略45度であることが好ましい。角度αが45度であると、手提げ袋を開いたときに、図11に示すように、直方体の袋の側面の下部に直角二等辺三角形の折り重ね部分が形成される。図10において、cが手提げ袋を開いたときに形成される直方体形状の袋体の深さとなる。cは、収納する物品の量に応じて適宜選択することができるが、新聞古紙専用の回収袋として用いるときは、30〜40cmであることが好ましい。
本発明方法において、下側の溶着線は、手提げ袋の両側端にあたる溶着線の先端部25において、側縁と平行になる方向に湾曲していることが好ましい。したがって、(4)ガゼット折りされたフィルム2枚ずつを溶着する工程において用いる略V字形の熱溶着刃は、このような溶着線の形状に対応する形状であることが好ましい。先端部において側縁と平行になる方向に湾曲した溶着線は、手提げ袋を開いて直方体形状の袋としたとき、先端部において水平方向に湾曲するので、手提げ袋に新聞古紙などを収納して運搬するときにかかる応力を水平方向に分散し、溶着線の先端部への応力の集中を防ぐので、溶着線の先端部における手提げ袋の破損を防止することができる。
FIG. 10 is a plan view of an embodiment of the handbag manufactured by the method of the present invention and an end view taken along the line AA, and FIG. 11 is a perspective view showing a state in which the handbag is opened. Since the handbag manufactured by the process shown in FIG. 1 becomes a finished product in a folded state as shown in FIG. 10, it can be packed and stored and transported as it is.
When the handbag shown in FIG. 10 is opened, the uncut gusset fold 17 is opened to form a rectangular bottom surface having a short side length 2a and a long side length b. When the handbag of the present invention is used as a newspaper magazine collection bag, when one side of a newspaper is folded into four, it becomes a rectangle with a short side length of about 20 cm and a long side length of about 27 cm. Since it is slightly broken, a, that is, the depth of the gusset fold that is not cut is preferably 10.5 to 12 cm, and b is preferably 28 to 32 cm.
The angle α formed by the lower welding wire 18 and the side edge of the belt-like film is preferably about 45 degrees. When the angle α is 45 degrees, when the handbag is opened, a folded portion of a right-angled isosceles triangle is formed at the lower part of the side surface of the rectangular parallelepiped bag as shown in FIG. In FIG. 10, c is the depth of the rectangular parallelepiped bag formed when the handbag is opened. c can be appropriately selected according to the amount of articles to be stored, but is preferably 30 to 40 cm when used as a collection bag exclusively for used newspaper.
In the method of the present invention, it is preferable that the lower welding wire is curved in a direction parallel to the side edge at the distal end portion 25 of the welding wire corresponding to both side ends of the handbag. Therefore, it is preferable that the substantially V-shaped heat welding blade used in the step of (4) welding two gusset-folded films each has a shape corresponding to the shape of such a welding line. The welding line that is curved in the direction parallel to the side edge at the front end is bent horizontally when the handbag is opened to form a rectangular parallelepiped bag. Since sometimes stress is dispersed in the horizontal direction and stress concentration on the tip of the weld line is prevented, damage to the handbag at the tip of the weld line can be prevented.

図10において、内部中央の折り目が切断されたガゼット折り19は、手提げ袋を開いたときに、手提げ部20を形成し、打ち抜き部21に手を入れて2条の手提げ部を把持し、手提げ袋を運搬することができる。手提げ部を形成するガゼット折りの深さに特に制限はなく、収納する物品の重量、プラスチックフィルムの厚さ、手提げ袋の使い勝手などに応じて適宜選択することができるが、開かれた手提げ袋の開口部において、2条の手提げ部が重なり合わないように、手提げ部を形成するガゼット折りの深さは、切断されない底面を形成するガゼット折りの深さよりも浅いことが好ましい。
図10において、上側の溶着線22が帯状フィルムの側縁となす角度βは、側縁近傍においては略45度であることが好ましく、溶着線の先端部23において、側縁と平行になる方向に湾曲していることが好ましい。したがって、(4)ガゼット折りされたフィルム2枚ずつを溶着する工程において用いる略V字形の熱溶着刃は、このような溶着線の形状に対応する形状であることが好ましい。先端部において側縁と平行になる方向に湾曲した溶着線は、手提げ袋を開いて直方体形状の袋としたとき、先端部において水平方向に湾曲するので、回収袋に新聞古紙などを収納して運搬するときにかかる応力を水平方向に分散し、溶着線の先端部への応力の集中を防ぐので、溶着線の先端部における手提げ袋の破損を防止することができる。
