Abstract
Description
本発明は、偏平な製袋用の合成樹脂チューブ体における出来上がった袋体に内容物を袋詰めしたときに袋体の表裏面及び両側面になる部位への印刷方法及びその合成樹脂製チューブ体による袋体の製造方法に関するもので、精米、肥料、園芸用の土や水苔、その他各種袋詰めしたときにその袋体の側面全体に文字・模様・図柄その他諸々の表示物が袋体の側面幅の全体にわたって大きくグラビヤ印刷によって連続表示できるようにすると共に、チューブ体の巻き取り工程中にその側面幅内に脱気用の微細孔を設けられるようにしたことを目的とする。 The present invention relates to a method for printing on the front and back surfaces and both side surfaces of a bag body when the contents are packed into the finished bag body in a flat synthetic resin tube body for bag making, and the synthetic resin tube body This is related to the method of manufacturing bags by using rice, fertilizer, soil for gardening, moss, and other various types of bags. An object of the present invention is to enable continuous display by gravure printing over the entire side width and to provide deaeration fine holes in the side width during the winding process of the tube body.
一般にこの種の袋体は、その表面に広告表示を施し、裏面に品名・品質・原料等の表示や製造メーカー等を表示することが行われている。
また、袋詰めした側面にも広告等の表示を施すことが行われている。そして、その袋体に前記の表示を施すのに、両側の折り目を境にして扁平にした袋体の表面と裏面に分けて印刷表示を行うのが普通である。そして、袋詰めしたときの側面部位にも広告等の表示が施される。
In general, this type of bag body has an advertisement display on its front surface and displays the name, quality, raw materials, etc., and the manufacturer on the back surface.
In addition, advertisements and the like are also displayed on the side of the bag. In order to display the above-mentioned display on the bag body, it is common to perform print display separately on the front and back surfaces of the bag body flattened with folds on both sides as a boundary. An advertisement or the like is also displayed on the side portion when the bag is packed.
一方で、内容物を袋詰めしたときに、袋体内に空気が残留していると、その分嵩張ると共に、これを段積みしたときに安定性に欠けて滑落する危険がある。そのため、従来においても合成樹脂製の包装袋に脱気用の孔を設けることは行われている。 On the other hand, when the contents are packed in the bag, if air remains in the bag body, it becomes bulky, and there is a risk of slipping due to lack of stability when stacked. Therefore, conventionally, providing a hole for deaeration in a packaging bag made of synthetic resin has been performed.
そのうち、脱気孔が大きいと内容物が零れるので蓋が必要となる。そこで、最近は、ポリエチレン製の収容袋にレーザー光線加工によって無数の微細の孔を設けることが行われている。 Of these, if the deaeration holes are large, the contents are spilled and a lid is required. Therefore, recently, innumerable fine holes have been provided in a polyethylene container bag by laser beam processing.
ところが、前記の袋体において、側面に広告等の表示を施すのに従来は、扁平の折り目を境にしてその表面部と裏面部とに分けて印刷表示が行われるのが普通である。そのため、前記の折り目を境に片側だけの表示は小さく目につきにくい（図７参照）。 However, in order to display advertisements or the like on the side surfaces of the bag body, conventionally, printing display is usually performed by dividing the flat fold into a front surface portion and a back surface portion. For this reason, the display on only one side of the fold line is small and difficult to see (see FIG. 7).
また、折り目を境にして両側にわたって連続する表示を施すと、表示物が大きくなって目につきやすいが、折り目には印刷ができないので、その連続表示物の出来映えは完全ではなく、筋目が不体裁に目立って良好な表示物が得られない。
なお、袋体の折り目にも印刷表示できるようにしたものは、従来においても公表されてはいる。例えば、特許文献１の特開昭62−183377号、同文献２の特開昭62−268643号、同文献３の特開昭63−182180号の各公報の袋状物の縦筋の部位にも胴周方向に連続する模様が施せる発明が表示されている。
In addition, if continuous display is performed on both sides with a crease as the boundary, the display object becomes large and easily noticeable, but printing is not possible on the crease, so the result of the continuous display object is not perfect, and the streak is not good In this case, a good display cannot be obtained.
In addition, what can be printed and displayed on the folds of the bag has also been publicly disclosed. For example, in the longitudinal muscles of the bag-like material of Japanese Patent Application Laid-Open Nos. Sho 62-183377, No. 62-268643, and No. 63-182180, the same document. Also, an invention that can give a continuous pattern in the waist circumference direction is displayed.
しかしながら、前記３件の公知技術は、いずれも袋体物の中に角柱又は円柱ないし板状に弾性変形できるようにしたアンダープレートを挿入し、その袋状物の正面又は背面にスクリーン印刷を行うものである。
従って、ロール巻きされている長尺のチューブ体を繰り出して連続且つ自動的に印刷表示することを狙いとしているものではなく、1袋づつ手作業で印刷することを前提としていて、本願発明の目的とは異なる。
However, each of the three known techniques inserts an under plate that can be elastically deformed into a prism or cylinder or plate into the bag body, and performs screen printing on the front or back of the bag. Is.
Therefore, it is not intended to continuously and automatically print and display a long tube body that has been rolled up, and is based on the premise that printing is performed manually one bag at a time. Is different.
そこで、本願発明者ら及び出願人が特許文献４の特許発明を提供して、段積みした米袋の側面に従来の広告表示（図７）に比べて相当に大きな広告を表示できるようになった（図６参照） Therefore, the inventors of the present application and the applicant have provided the patented invention of Patent Document 4 so that a considerably larger advertisement can be displayed on the side surface of the stacked rice bag than the conventional advertisement display (FIG. 7). (See Figure 6)
一方、最近は袋体の側面にレーザー加工により無数の微細孔を設けるものが主流になっている。そして、従来の微細孔の加工は、グラビア印刷を行ったそのチューブ体の扁平状態で行う。ちなみに、レーザー（LASER）は、Light Amplification by Stimulated Emission of Radiationの略であり、人工の光で自然光とは異なる特性を活かし、その人工光線の照射することで微細孔が設けられる。 On the other hand, recently, the one that has innumerable fine holes by laser processing on the side surface of the bag has become mainstream. And the process of the conventional micropore is performed in the flat state of the tube body which performed the gravure printing. By the way, laser (LASER) is an abbreviation for Light Amplification by Stimulated Emission of Radiation, and it uses artificial light to take advantage of characteristics that are different from natural light.
すなわち、上記従来の工法は、成形加工時にレーザー光の照射で複数の微細孔を開けておき、その後にチューブ体に所定の印刷を施し、袋体加工を行って製品としている。 That is, in the above-described conventional method, a plurality of fine holes are formed by laser light irradiation during molding, and then a predetermined printing is performed on the tube body to process the bag body to obtain a product.
これに対して上記特許文献４に係る袋体成形にあっては、チューブ体成形工程で、所定の側面幅を成形するために当該チューブ体内に空気を送り込んで膨らます必要がある。しかしながら、その前工程で扁平状態のチューブ体に微細な穿孔を設けると、空気をチューブ体内に空気を送り込んでも微細孔から空気が漏れて膨らますことができない。 On the other hand, in the bag forming according to the above-mentioned Patent Document 4, it is necessary to inflate air into the tube body in order to form a predetermined side width in the tube body forming step. However, if fine holes are provided in the flat tube body in the previous process, even if air is fed into the tube body, the air cannot leak and swell from the fine holes.
そのため、ポリエチレン製チューブ体に所定の側面幅を成形する袋体の成形工程中にレーザー加工で微細孔を設けることはできないとされていた。 For this reason, it has been said that fine holes cannot be formed by laser processing during the forming process of the bag body for forming a predetermined side width on the polyethylene tube body.
本発明者らは鋭意研究の結果、あらかじめチューブ体の成形・印刷した後、チューブ体内に空気を注入して膨らましながら、両側面に所定のマチ幅を成形する折り目を形成した後に再度扁平にして巻き取りを行う途中でレーザー光の照射穿孔により無数の微細孔を設けることができるようにした。 As a result of diligent research, the present inventors have formed and printed the tube body in advance, and then inflated it by injecting air into the tube body, and then forming a crease that forms a predetermined gusset width on both sides, and then flattening again. Innumerable fine holes can be formed by laser beam irradiation drilling during winding.
本発明の第１は、偏平な製袋用合成樹脂チューブ体における出来上がった袋体に内容物を袋詰めしたときに袋体の表裏面及び両側面になる部位への印刷方法において、インフレーション方式により得た長尺の薄肉のチューブ体に折り目を付けて偏平にしながらロール状に巻取ってロール巻きを形成し、該ロール巻きから繰り出した偏平なチューブ体の表裏面における、出来上がった袋体に内容物を袋詰めしたときに袋体の表面になる部位及び一側面になる部位に同時にグラビヤ印刷を施すと共に、前記表裏面における、出来上がった袋体に内容物を袋詰めしたときに袋体の裏面になる部位及び他側面になる部位に同時にグラビヤ印刷を施した後に、印刷済みの偏平なチューブ体をロール状に巻き取る第１工程と、第１工程によって巻き取った偏平なチューブ体のロール巻きからチューブ体を第１の押圧ローラーを介して繰り出し、この繰り出し開始時に、偏平になっていたチューブ体の開口端からチューブ体内部に圧縮空気を注入してチューブ体を膨らませ、前記開口端を第２の押圧ローラーで挟圧することにより前記一側面となる部位の胴周方向中央および前記他側面となる部位の胴周方向中央に折り目を付けて再度偏平にすることにより注入された空気によりふくらんでいるチューブ体の部分をドーム状にし、以後、第１の押圧ローラを介して偏平なチューブ体を繰り出しながら、チューブ体のドーム状の部分を胴周方向にずらしながら、第２の押圧ローラーの挟圧によりふくらんでいるチューブ体の前記一側面となる部位の胴周方向中央及び前記他側面となる部位の胴周方向中央に折り目を付けてチューブ体を再度偏平にしながら、再度偏平になったチューブ体をロール状に巻き取る第２工程の途中に配置したレーザー光線照射装置によって、微細孔をチューブ体の長手側面に沿って単一列又は複数列に設けたものである。 A first aspect of the present invention is a method for printing on the front and back surfaces and both side surfaces of a bag body when the contents are packed in a completed bag body in a flat synthetic resin tube body for bag making, by an inflation method. The obtained long and thin tube body is creased and flattened, wound into a roll shape to form a roll roll, and the contents of the finished bag body on the front and back surfaces of the flat tube body fed out from the roll winding Gravure printing is performed simultaneously on the front surface and one side surface of the bag when the product is packaged, and the back surface of the bag when the contents are packed in the completed bag on the front and back surfaces. After the gravure printing was simultaneously performed on the part to become and the part to become the other side, the printed flat tube body was wound up in a roll shape, and wound up by the first process The tube body is fed out from the roll of the flat tube body through the first pressing roller, and at the start of the feeding, the compressed air is injected into the tube body from the open end of the flat tube body to remove the tube body. By inflating and clamping the opening end with a second pressing roller to crease and flatten the center of the body circumferential direction of the part serving as the one side surface and the center of the body circumferential direction of the part serving as the other side surface again The portion of the tube body that is inflated with the injected air is made into a dome shape, and then the dome-shaped portion of the tube body is shifted in the circumferential direction while the flat tube body is fed out via the first pressing roller. The trunk circumference direction center of the part that becomes the one side surface of the tube body that is inflated by the clamping pressure of the second pressing roller and the circumference direction of the part that becomes the other side surface The micropores are formed along the longitudinal side surface of the tube body by a laser beam irradiation device disposed in the middle of the second step of winding the tube body flattened again in a roll shape while making the tube body flat again with a crease in the center. Provided in a single row or multiple rows.
本発明の第２は、偏平な製袋用合成樹脂チューブ体における出来上がった袋体に内容物を袋詰めしたときに袋体の表裏面及び両側面になる部位への印刷方法において、インフレーション方式により得た長尺の薄肉のチューブ体に折り目を付けて偏平にしながらロール状に巻取ってロール巻きを形成し、該ロール巻きから繰り出した偏平なチューブ体の表裏面における、出来上がった袋体に内容物を袋詰めしたときに袋体の表面になる部位および一側面になる部位に同時にグラビヤ印刷を施すと共に、前記表裏面における、出来上がった袋体に内容物を袋詰めしたときに袋体の裏面になる部位及び他側面になる部位に同時にグラビヤ印刷を施した後に、印刷済みの偏平なチューブ体をロール状に巻き取る第１工程と、第１工程によって巻き取った偏平なチューブ体のロール巻きからチューブ体を第１の押圧ローラーを介して繰り出し、この繰り出し開始時に、偏平になっていたチューブ体の開口端からチューブ体内部に圧縮空気を注入してチューブ体をふくらませ、前記開口端を第２の押圧ローラーで挟圧することにより前記一側面となる部位の胴周方向中央及び前記他側面となる部位の胴周方向中央に折り目を付けて再度偏平にすることにより注入された空気によりふくらんでいるチューブ体の部分をドーム状にし、以後、第１の押圧ローラーを介して偏平なチューブ体を繰り出しながら、チューブ体のドーム状の部分を胴周方向にずらしながら、第２の押圧ローラーの挟圧によりふくらんでいるチューブ体の前記一側面となる部位の胴周方向中央および前記他側面となる部位の胴周方向中央に折り目を付けてチューブ体を再度偏平にしながら、再度偏平になったチューブ体をロール状に巻き取る第２工程の途中に配置したレーザー光線照射装置によって、微細孔をチューブ体の長手側面に沿って単一列又は複数列に設け、第２工程でロール状に巻き取ったチューブ体を再度繰り出してその所定の長さの位置において、幅方向にわたって偏平なチューブ体を溶着して底部を形成した後、その溶着部の外側に沿って裁断する第３工程とから成り、出来上がった袋体に内容物を袋詰めした状態における表裏面及び両側面にグラビヤ印刷した表示物が表示されるようにしたものである。 The second aspect of the present invention is a method for printing on the front and back surfaces and both side surfaces of the bag body when the contents are packed in the completed bag body in a flat synthetic resin tube body for bag-making. The obtained long and thin tube body is creased and flattened, wound into a roll shape to form a roll roll, and the contents of the finished bag body on the front and back surfaces of the flat tube body fed out from the roll winding Gravure printing is performed simultaneously on the surface and one side of the bag when the product is packed, and the back of the bag when the contents are packed into the finished bag on the front and back surfaces. After the gravure printing is simultaneously performed on the part to become and the part to become the other side, the printed flat tube body is wound up in a roll shape, and wound up by the first process. The tube body is fed out from the roll of the flat tube body through the first pressing roller, and at the start of the feeding, the compressed air is injected into the tube body from the open end of the flat tube body. By inflating and clamping the opening end with a second pressing roller, crease the flat part in the trunk circumferential direction of the part that becomes the one side surface and the central part in the trunk circumferential direction of the part that becomes the other side surface. While making the portion of the tube body which is inflated by the injected air into a dome shape, and then feeding out the flat tube body through the first pressing roller, shifting the dome shape portion of the tube body in the circumferential direction, The center of the body circumferential direction of the portion that becomes the one side surface of the tube body that is inflated by the clamping pressure of the second pressing roller and the body that becomes the other side surface The micropores are formed in the longitudinal side surface of the tube body by a laser beam irradiation device arranged in the middle of the second step of winding the tube body flattened again in a roll shape while making the tube body flat again by making a crease in the center of the direction. The tube body which is provided in a single row or a plurality of rows along and rolled up in the second step is drawn out again, and at the position of the predetermined length, a flat tube body is welded in the width direction to form a bottom portion. After that, it consists of a third step of cutting along the outside of the welded portion, and gravure-printed display items are displayed on the front and back surfaces and both side surfaces in the state in which the contents are packed in the completed bag body. Is.
本発明は上記の構成であるから、袋体の表面には、メイン広告が表示され、且つ裏面にはブランド、キャラクタ、品名、メーカー名等の表示が表示されると共に、その両側面にも幅方向の全面にわたって広告が表示される。これによって、製品を袋詰めした袋体を多段に積み上げたときでも下から袋体の側面の広告が一目ではっきりと視認でき、その宣伝広告の効果が倍加する。 Since the present invention is configured as described above, the main advertisement is displayed on the front surface of the bag body, and the display of brand, character, product name, manufacturer name, etc. is displayed on the back surface, and the width is also provided on both side surfaces thereof. Ads are displayed across the entire direction. As a result, even when the bags packed with products are stacked in multiple stages, the advertisement on the side of the bag can be clearly seen at a glance from the bottom, and the effect of the advertisement is doubled.
そして、その側面に印刷する手段は、折り目が入っていない扁平の状態において表面部の印刷又は裏面部の印刷と同時に行うから、その印刷、製袋、裁断、繰り出し、巻取り等の一連の作業を機械によって自動的に行うのに適し、量産が可能である。 And since the means for printing on the side surface is performed simultaneously with the printing of the front surface part or the back surface part in a flat state without a crease, a series of operations such as printing, bag making, cutting, feeding, winding, etc. It is suitable for performing automatically by a machine, and mass production is possible.
さらに、チューブ体の印刷時点においては、側面の印刷表示が表面又は／及び裏面に位置しているが、製袋のための繰り出し途中において当該チューブ体を胴周方向に設定した寸法だけずらして折り目を付けることによって、その表示が製袋の側面に位置することができる。 Furthermore, at the time of printing the tube body, the side printed display is located on the front surface and / or the back surface. However, the tube body is shifted by a dimension set in the circumferential direction in the middle of feeding for bag making. The display can be positioned on the side of the bag making.
また、その袋体側面の広告は、その表示の中央に筋目が入っているが、これは印刷した後に、胴周方向にずらして付けられたものであるから、その印刷部分が筋目にかかっていても、印刷が飛んで途切れたりすることはなく、文字、模様、キャラクタ、その他の各種の広告が連続してきれいに表示され、商品価値を高めることができる。 Also, the advertisement on the side of the bag body has a streak in the center of the display, but since this is printed and shifted in the circumferential direction, the printed part is striking. However, printing does not skip and is not interrupted, and characters, patterns, characters, and other various advertisements are continuously displayed neatly, and the product value can be increased.
そして、チューブ体をふくらませて所定の側面マチ幅を成形し、その後、再度チューブ体を扁平させながら巻き取り移動する途中で、当該側面の長手に沿ってレーザー加工機からのレーザー光を照射して穿孔することにより、無数の微細孔を設けることができる。 Then, the tube body is expanded to form a predetermined side gusset width, and then the laser beam from the laser processing machine is irradiated along the length of the side surface while the tube body is wound up while being flattened again. Innumerable fine holes can be provided by drilling.

「具体的な印刷・所定側面幅・微細孔の工程例」
次に、合成樹脂製チューブ体側面に印刷表示した袋体の製造工程を説明する。
（１） 第1工程（グラビヤ印刷工程）図示省略インフレーション方式により得た超長尺の薄肉チューブ体に折り目を付けてロール状に巻取っておき、前記ロール巻きから繰り出して扁平の表面部に当該表面部位と一側面部位及び扁平の裏面に当該裏面部位と他側面部位に公知のグラビヤ印刷方法によって所定の表示物を施した後にロール状に巻き取る。前記のチューブ体は、一袋の長さに相当するピッチで自動的に送り、且つその一袋に相当する部位にグラビヤ印刷６〜９を自動且つ連続して行うものである。
（２） 第２工程（印刷側面ずらし工程）第１工程における、ロール状に巻きとられているロール巻きＲから繰り出した扁平薄肉チューブ体１０を、図４に示すように第１の押圧ローラー２１を介して送ると共に、この繰り出し開始時に該チューブ体の開口端から内部に圧縮空気を注入してドーム状を形成し、以後、偏平薄肉チューブ体１０を第1押圧ローラーで送りながら、ドーム状のチューブ体表面２の一側面幅ｗlと、裏面３の他側面幅ｗ2を胴周方向に前記幅の２分の１だけずらしながら、その両側面幅ｗl・ｗ2の中央線位置cに沿って折り、ガイド部材２２を介し、さらに別のローラー２３を介して巻き取り角度を変えながら、且つ第２の押圧ローラー２４で挟圧して折り目１０３・１０４を付けて扁平チューブ体を次のロール状に巻き取る工程に送る。
（３） チューブ体の送る途中においてレーザー光照射装置２７によって、チューブ体１０の側面幅の長さ方向の縁辺に照射し、当該チューブ体の巻き取り移動しながら連続して微細孔１２を穿設する。当該微細孔１２の径は、米袋にあける場合は、大きくても米粒がこぼれない径とするが、実際には無数に穿孔するため、好ましくは直径５０〜３００μｍの微細孔１２を長さ方向の間隔l′＝４〜６ｍｍ、２列の横幅方向の間隔w′＝２〜４ｍｍを可とする（図４参照）。また、その微細孔は、扁平チューブ体の上面側の１枚だけに穿孔するものである。その理由は、上下２枚に穿孔すると、その２枚が溶着してしまうので好ましくない。
（４） 微細孔１２を穿孔し終わった扁平チューブ体１０はロール状に巻き取られてロール巻きＲ′を形成する。
（５） 第３工程（製袋工程）図示省略： チューブ体１０を巻き取ったロール巻Ｒ′を再度繰り出して所定の長さLの位置において、幅Ｗの方向にわたって溶着し、その溶着部１１で底部を形成した後、その溶着部の外側に沿って裁断すると、その裁断個所が開口となって１枚分の袋体１が作製される。
そして、製品を袋詰めしたあとは開口を溶着して接着部１１′を形成して閉塞する。
"Specific printing, predetermined side width, and micro-hole process examples"
Next, the manufacturing process of the bag body printed and displayed on the side surface of the synthetic resin tube body will be described.
(1) First step (gravure printing step) The ultra-long thin tube body obtained by the inflation method not shown is creased and wound into a roll shape, and the surface portion is drawn out from the roll winding to the surface portion of the flat surface. And after giving a predetermined display thing to the said back surface part and other side part by the well-known gravure printing method to one side surface part and a flat back surface, it winds up in roll shape. The tube body automatically feeds at a pitch corresponding to the length of one bag and automatically and continuously performs gravure printing 6 to 9 on a portion corresponding to the one bag.
(2) Second step (printing side shifting step) In the first step, the flat thin-walled tube body 10 drawn out from the roll R wound in the form of a roll, as shown in FIG. At the start of the feeding, compressed air is injected from the open end of the tube body to form a dome shape. Thereafter, the flat thin-walled tube body 10 is fed by the first pressing roller, The center line position c of both side surface widths w l and w 2 while shifting one side surface width w l of the tube body surface 2 and the other side surface width w 2 of the back surface 3 in the body circumferential direction by a half of the width. The flat tube body is formed by attaching the folds 10 3 and 10 4 with the second pressing roller 24 while changing the winding angle through the guide member 22 and further through another roller 23, and by pressing with the second pressing roller 24. Wound into the next roll Send to scraping process.
(3) During the feeding of the tube body, the laser beam irradiation device 27 irradiates the edge in the length direction of the side surface width of the tube body 10 and continuously drills the fine holes 12 while winding and moving the tube body. To do. The diameter of the fine holes 12 is a diameter at which rice grains are not spilled even when they are large, but in practice, the holes are perforated innumerably. The interval l ′ = 4 to 6 mm and two rows in the horizontal width direction w ′ = 2 to 4 mm are allowed (see FIG. 4). Moreover, the micropore is perforated only in one sheet on the upper surface side of the flat tube body. The reason is that if two holes are perforated, the two sheets are welded, which is not preferable.
(4) The flat tube body 10 that has finished drilling the fine holes 12 is wound into a roll to form a roll R ′.
