カートンブランクと鋸刃カッターの組合体 技 術 分 野  Union of carton blanks and saw blade cutters
本発明は， アルミホイル、 ラッピングフィルム等を収容する鋸刃カッター付力 一トンの製造に当たって、 カートンブランクへ鋸刃カッターを接着する方法、 そ の鋸刃力ッターとして用いるのに好適な鋸刃力ッター、 および力一トンブランク と鋸刃力ッターの組合体に関する。  The present invention relates to a method for bonding a saw blade cutter to a carton blank in the production of one ton in which a saw blade cutter for accommodating aluminum foil, wrapping film, etc. And a combination of a one-ton blank and a saw blade power cutter.
背 景 技 術  Background technology
従来、 巻取状態のアルミホイル、 プラスチックのラッピングフィルム等を収容 した直方体状のカートンに、 側縁に鋸刃を形成した金属製の鋸刃力ッターを取り 付けておき、 アルミホイルやラッピングフィルム等を引き出し、 その鋸刃カツタ 一を用いて切り離すように構成したものが広く使用されている。 しかし、 金属製 の鋸刃カッターは焼却できず、 廃棄に問題があった。 そこで、 金属製の鋸刃カツ ターに代えて紙等の非金属の鋸刃カッター、 例えばバルカナイズドファイバー製 の鋸刃カッターを用いること力《提案されており、 例えば、 特開平 6— 4 8 4 2 8 号公報、 特開平 6— 1 4 4 4 2 5号公報に開示されている。  Conventionally, a metal saw blade power cutter with a saw blade formed on the side edge is attached to a rectangular parallelepiped carton containing rolled aluminum foil, plastic wrapping film, etc. It is widely used to pull out and to separate it using a saw blade cutter. However, metal saw blade cutters could not be incinerated, and had problems with disposal. Therefore, a non-metallic saw blade cutter such as paper, for example, a vulcanized fiber saw blade cutter has been proposed in place of a metal saw blade cutter (for example, see Japanese Patent Application Laid-Open No. 6-48482). No. 8 and Japanese Patent Application Laid-Open No. 6-144424.
バルカナイズドフアイバー製等の非金属の鋸刃力ッターをカートンブランクに 接着するには、 金属製の鋸刃カッターのようにかしめを利用することができない ので、 "^に鋸刃カッター全体をホットメルト系或いはェマルジヨンタイプの接 着剤 （糊） で接着していた。 また、上記の特開平 6— 4 8 4 2 8号公報では鋸刃 力ッター全体を超音波溶着で接着しており、 特開平 6 - 1 4 4 4 2 5号公報では まず、 鋸刃カッターを超音波溶着或いは接着剤でスポット的に仮接着し、 その後 全体を超音 着またはヒートシールしていた。 To glue a non-metal saw blade power cutter made of Vulcanized Fiber to a carton blank, caulking cannot be used like a metal saw blade cutter. Alternatively, in the above-mentioned Japanese Patent Application Laid-Open No. 6-48428, the entire saw blade power cutter is bonded by ultrasonic welding. According to Kaihei 6-1 4 4 4 25, first, the saw blade cutter is temporarily bonded by ultrasonic welding or spot bonding with an adhesive. The whole was supersonic or heat sealed.
しかし、 接着剤を用いて鋸刃力ッ夕一全体をカートンブランクに接着した場合 には、 使用中に鋸刃カッターの両端が浮き上がって見栄えが悪くなつたり、剥が れて^できなくなることがあるという P題があつた。 この問題の原因を検討し た結果、 次の事項を見出した。 すなわち、 接着剤で鋸刃カッターをカートンブラ ンクに接着する場合、接着剤が圧着により広がり、 鋸刃カッターの外に漏れるの を防止するため、接着剤の塗布幅および塗布長さを鋸刃力ッターの幅および長さ よりも小さくしており、 このため接着剤のつかない部分が生じており、特に鋸刃 力ッターの両端に接着剤の無い部分力生じている。 このような部分は剥がれやす く、 特に鋸刃カッターが吸水性を有していた場合、 ¾τ によって伸びようとして 剥がれることがある。 しかも、 鋸刃カッターでアルミホイル或いはラッピングフ イルム等を切断する際に、鋸刃カッターの端部に大きい力が加わり、 この点から も剥がれやすい。 このため、 使用中に鋸刃カッターの両端に浮き上がりや剥がれ が多く発生していた。  However, if the entire saw blade is glued to the carton blank using an adhesive, both ends of the saw blade cutter may rise during use, resulting in poor appearance or peeling off. There was a P title. After examining the cause of this problem, we found the following. In other words, when gluing the saw blade cutter to the carton blank with adhesive, the width and length of the adhesive applied must be adjusted to prevent the adhesive from spreading by crimping and leaking out of the saw blade cutter. It is smaller than the width and length of the cutter, which results in adhesive-free parts, especially adhesive-free partial forces at both ends of the saw blade. Such a part is easy to peel off, especially when the saw blade cutter has water absorbency, and may peel off due to Δτ. Moreover, when cutting the aluminum foil or the wrapping film with the saw blade cutter, a large force is applied to the end of the saw blade cutter, and it is easy to peel from this point. For this reason, many lifting and peeling occurred at both ends of the saw blade cutter during use.
また、 特開平 6 - 4 8 4 2 8号公報および特開平 6 - 1 4 4 4 2 5号公報に示 されるように、鋸刃カッター全面を超音波溶着する場合には、 シールに使うボー ンの形状が横長となり、耐久性に欠けるとか、 大きい面積をシールするために大 出力を要する等の問題があった。 なお、 特開平 6 - 1 4 4 4 2 5号公報に示され るように円 ホーンを用いることも可能であるが、 この場合には装置力《複雑と なるという問題があった。 また、 鋸刃カッター全面をヒー卜シールする場合にも、 大出力を^とすると共にヒートシ一ル面が細長くなるので^の均一化や均等 な押圧が困難で、 接着力にむらが生じやすく、 し力、も、 ヒートシールに時間がか かり、 ： ^性が悪いという問題があった。  Also, as disclosed in JP-A-6-48428 and JP-A-6-144425, when ultrasonic welding is performed on the entire surface of a saw blade cutter, a boll used for sealing is used. There are problems such as that the shape of the housing becomes oblong and lacks durability, and a large output is required to seal a large area. It is also possible to use a circular horn as disclosed in Japanese Patent Application Laid-Open No. 6-144425, but in this case, there is a problem that the device power becomes complicated. Also, when the entire surface of the saw blade cutter is heat-sealed, it is difficult to equalize and evenly press the ^ because the large heat output and the heat seal surface are elongated, and the adhesive strength is likely to be uneven. The heat sealing took a long time, and there was a problem of poor properties.

以下、本発明の な^例を説明する。  Hereinafter, examples of the present invention will be described.
図 6は、 後述する本発明の一 例による接着方法によつて接着するカートン ブランク 1と非金属の鋸刃カッター 2を示すものである。 鋸刃カッター 2は、 長 尺の原反の先端を鋸刃状に切断して切り離すことにより作られており、 その両側 縁に鋸刃 2 a , 2 bを有している。 この鋸刃カッター 2をカートンブランク 1の 表面の斜線で示す領域 3に貼り付け、 その後、 カートンブランク 1を箱状に組み 立てることにより、 図 7に示すように、 鋸刃カッター 2を一方の鋸刃 2 a力角部 から突出するように取り付けたカートン 1 Aを形成でき、 このカートン 1 Aにァ ルミホイル、 ラッピングフィルム等を収容しておき、 使用時にそれを引き出し、 鋸刃カッター 2の鋸刃 2 aで切り離すことができる。 なお、鋸刃カッター 2の力 一トンブランク 1に対する貼り付け位置は図 6に示す位置に限らず、 例えば、 図 8に示すようにカートンブランク 1の掩蓋片 1 aの裏面側の領域 3 A (開封用の ミシン目 4に沿った領域） といしてもよい。  FIG. 6 shows a carton blank 1 and a non-metal saw blade cutter 2 bonded by a bonding method according to an example of the present invention described later. The saw blade cutter 2 is made by cutting and cutting the end of a long web into a saw blade shape, and has saw blades 2a and 2b on both side edges. This saw blade cutter 2 is attached to the hatched area 3 on the surface of the carton blank 1, and then the carton blank 1 is assembled in a box shape, as shown in FIG. Blade 2a Carton 1A attached to project from the corner of force can be formed. This carton 1A contains aluminum foil, wrapping film, etc., and pulls it out when used, and the saw blade of saw blade cutter 2 2a can be separated. Note that the position of the saw blade cutter 2 to be applied to the one-ton blank 1 is not limited to the position shown in FIG. 6 .For example, as shown in FIG. 8, the area 3 A ( (The area along the perforation 4 for opening).
鋸刃カッター 2を形成するための原反としては、 鋸刃として^するための適 度な硬さと、超音波シールやヒートシール可能な溶着性を有する非金属材料が使 用される。 な原反材料としては、 長 i¾iitの木材パルプを主原料とし、無サイ ズで若しくは のサイ ^を添加して抄造した原紙に樹脂を含浸させてなる樹 脂含^ ftを挙げることができる。 ここで、 樹脂含浸紙の樹脂含 としては、 含 浸用原紙 1 0 0 部に対して榭脂 5 0〜8 0 MS部が好適である。 すなわち、 樹脂分が 5 0 M*部よりも小さいと、 が低くて鋸刃力ッターとしての効果が 悪くなり、 一方、 8 0SS部を越えると棚旨含浸が困難となるから、 上記の範囲 が である。 なお、 原紙の抄造の際に添加するサイ の量としては、 上記範 囲の樹脂分を含浸させることができる原紙を抄造できるように定めるものであり、 サイズ剤の添加量を調整してサイズ度 （液の浸透に対する抵抗度合い） を調整す ることにより、 樹脂含浸量をコントロールすることができる。 As a raw material for forming the saw blade cutter 2, a nonmetallic material having a suitable hardness for forming a saw blade and a welding property capable of ultrasonic sealing and heat sealing is used. The main raw material is wood pulp made from long i¾iit, Resin impregnated resin obtained by impregnating a resin into a base paper formed by adding a size or adding a resin. Here, the resin content of the resin-impregnated paper is preferably 50 to 80 MS parts per 100 parts of the base paper for impregnation. That is, if the resin content is less than 50 M *, the resin content is low, and the effect as a saw blade power meter is deteriorated.On the other hand, if the resin content exceeds 80 SS, it becomes difficult to impregnate the shelves. It is. The size of the paper to be added during the papermaking of the base paper is determined so that the base paper that can be impregnated with the resin component in the above range can be formed, and the amount of the sizing agent is adjusted to adjust the size. By adjusting (the degree of resistance to liquid penetration), the resin impregnation amount can be controlled.
樹脂含^ の厚みは、 鋸刃カッターとして使用する際の切れ味、 等を確保 するため、 0. 2〜0. 4 mmg¾が好適である。 また、榭脂含浸成分としては、 硬質水溶性アクリル樹脂で、例えば、 アクリル酸メチル、 アクリル酸ェチル、 ァ クリル酸プチル、 メタクリル酸メチル、 メタクリル酸ェチル、 メタクリル酸プチ ル等を挙げることができる。 なお、 樹脂含浸紙は、 表面に樹脂被膜を形成する等 の二 »]ェを行うことなく鋸刃カッターの原反として使用される。  The thickness of the resin content is preferably 0.2 to 0.4 mmg in order to ensure sharpness and the like when used as a saw blade cutter. Examples of the resin-impregnated component include hard water-soluble acrylic resins, such as methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, ethyl methacrylate, and butyl methacrylate. The resin-impregnated paper is used as a raw material of a saw blade cutter without performing a second step such as forming a resin film on the surface.
鋸刃力ッターの原反の他の例としては、 バルカナイズドフアイバを挙げること ができる。 但し、 バルカナイズドファイバは、 それ自体では溶着性を有していな いので、 少なくともカートンブランク 1と接着する側の表面に樹脂を被 Sして溶 着性を与えるもの力《使用される。 ここで使用する樹脂としては、 エチレン ·ァク リル酸コポリマー （アイオノマー） 、 エチレン ·プロピレンコポリマー、酢酸ビ 二ル系共重合ポリオレフィン等を挙げることができ、 これらをグラビアコーター 等で^ Xすればよい。 丁量 しては、 望ましくは 3〜6 g/m2 (乾燥状態） である。 Another example of a saw blade power cutter is Vulcanized Fiber. However, since the vulcanized fiber itself does not have a welding property, it is used to provide a welding property by applying a resin to at least the surface on the side to be bonded to the carton blank 1.

First, as shown in Fig. 1 (a), the predetermined position S of the carton plank 1 The adhesive 6 is discharged from the adhesive nozzle 5 and applied. This adhesive application can be performed by moving the carton blank 1 with respect to the adhesive nozzle 5 in the direction indicated by the arrow. Alternatively, the carton blank 1 may be stopped, and the adhesive nozzle 5 may be moved in the direction opposite to the arrow. The adhesive used here may be any one of a hot melt adhesive, an emulsion adhesive, and the like. For example, as a hot melt adhesive, EVA (ethylene-vinyl acetate copolymer resin), APP (actic-polypropylene) ), PE (polyethylene), SIS (styrene / isoprene copolymer resin), SBS (styrene / butadiene copolymer resin), polyamide resin, etc., and the emulsion adhesive is vinyl peroxylate. • An acryl copolymer resin, a modified acrylate copolymer resin, an acryl copolymer resin, a vinyl acetate resin, and the like can be given.
接着剤 6の塗布領域は、 その上の鋸刃力ッター 2を押し付けて接着した状態に おいて、 図 5に斜線で示すように接着剤 6が鋸刃力ッター 2のほぼ全長に渡って 存在するように定められる。 ただし、 鋸刃カッター 2を押し付けて加圧した時に、 接着剤 6力鋸刃力ッター 2の外側に漏れ出すことがないようにするため、 接着剤 6は鋸刃力ッター 2の全面積よりもかなり小さ t、®¾に塗布されており、 このた め、鋸刃カッター 2を貼り付けた忧態において、 その鋸刃カッター 2の両端には、 接着剤 6の存在しない領域 （端部） 2 c力、'少し、 例えば 2〜5 mmgJ^じる。 次に、 図 1 (b ) に示すように、 原反 7の先端を所定形状に打ち抜いた鋸刃力 ッターを形成し、 それをカートンブランク 1に塗布した接着剤 6の上に押し付け て接着する。 鋸刃カッターの打ち抜きおよび接着は図 2に示す装置によって行わ れる。 すなわち、 図 2において、 8はカートンブランク 1を搬送する搬送ローラ、 9はカートンブランク 1の鋸刃カッター貼り付け部分を支持する支持台、 1 0は 先端に鋸刃 1 0 aを備えた固定ダイ、 1 1は先端に前記鋸刃 1 0 aに嚙み合う鋸 刃 1 1 aを備えた移動ダイ、 1 2は移動ダイ 1 1を上下動させるシリンダ 1 3は原反 7を lg刃力ッター 2の幅に相当する長さづっ送り出す原反搬送ローラ である。 この装 Sによる動作は次のように行われる。 まず、 図 2 ( a ) に示すよ うに、 原反 7がその先端を、 固定ダイ 1 0の鋸刃 1 0 aより鋸刃カッター 2の幅 に等しい量だけ突出させた状態で停止しているものとする。 この時、 固定ダイ 1 0はその上の原反 7を吸着^^している。 なお、 吸着 する代わりに適当な クランプ手段で ί¾«的に固定してもよい。 The adhesive 6 is applied over almost the entire length of the saw blade power cutter 2 as shown by the diagonal lines in FIG. It is determined to be. However, to prevent the adhesive 6 from leaking out of the saw blade power cutter 2 when the saw blade cutter 2 is pressed and pressed, the adhesive 6 is larger than the entire area of the saw blade power cutter 2. It is applied to a very small surface, and therefore, when the saw blade cutter 2 is attached, both ends of the saw blade cutter 2 have no adhesive 6 at both ends (ends) 2 c force, a little, for example, 2-5 mmgJ ^ Next, as shown in FIG. 1 (b), a saw blade force cutter is formed by punching the end of the raw material 7 into a predetermined shape, and the adhesive is pressed onto the adhesive 6 applied to the carton blank 1 and adhered. . The punching and bonding of the saw blade cutter are performed by the apparatus shown in FIG. That is, in FIG. 2, 8 is a transport roller for transporting the carton blank 1, 9 is a support for supporting a portion of the carton blank 1 to which the saw blade cutter is attached, and 10 is a fixed die having a saw blade 10a at its tip. Reference numeral 1 1 denotes a moving die having a saw blade 11 a at the tip thereof, which engages with the saw blade 10 a. Reference numeral 12 denotes a cylinder for moving the moving die 11 up and down. Reference numeral 13 denotes a material transfer roller for feeding the material 7 by a length corresponding to the width of the lg blade force cutter 2. The operation by the device S is performed as follows. First, as shown in Fig. 2 (a), the web 7 is stopped with its tip protruding from the saw blade 10a of the fixed die 10 by an amount equal to the width of the saw blade cutter 2. Shall be. At this time, the fixed die 10 adsorbs the raw material 7 thereon. Instead of being adsorbed, it may be fixed temporarily by a suitable clamp means.
この状態で、接着剤 6を塗布されたカートンブランク 1が支持台 9の上に送り 込まれ、所定位置に位置決めされて固定される。 次に、 図 2 (b) に示すように、 移動ダイ 1 1力下降し、 固定ダイ 1 0と協働して原反 7の先端を鋸刃力ッター 2 として切り離し、 その雜刃カッター 2を真空吸着した状態で、 その下方に位置し ているカートンブランク 1の接着剤 6上に押し付ける。 これにより、 鋸刃カツ夕 一 2が接着剤 6によってカートンブランク 1に接着される。 その後、 移動ダイ 1 1が上昇して元の位置に戻り、 カートンプランク 1は次の工程に送られる。 ま た、原反搬送ローラ 1 3が原反 7を鋸刃カッター 2の幅に相当する長さだけ送り 出し、 次の動作に備える。 以下、 同様の動作を繰り返して、 カートンブランク 1 に対する鋸刃力ッター 2の接着が次々と行われる。 このようにしてカートンブラ ンク 1に接着された鋸刃カッター 2は、 図 5に示すようにそのほぼ全長を接着剤 6で接着されているが、 その両端には、 小面積ではあるが接着剤の無い領域 （端 部 2 c ) 力生じている。  In this state, the carton blank 1 to which the adhesive 6 has been applied is sent onto the support 9 and is positioned and fixed at a predetermined position. Next, as shown in FIG. 2 (b), the moving die 11 is lowered by 1 force, and the tip of the raw material 7 is cut off as a saw blade force cutter 2 in cooperation with the fixed die 10 and the blade 2 is removed. In the state of vacuum suction, press it onto the adhesive 6 of the carton blank 1 located below. Thereby, the saw blade cut 1 is bonded to the carton blank 1 by the adhesive 6. Thereafter, the moving die 11 rises and returns to the original position, and the carton plank 1 is sent to the next step. In addition, the raw material transport roller 13 sends out the raw material 7 by a length corresponding to the width of the saw blade cutter 2, and prepares for the next operation. Hereinafter, the same operation is repeated, and the bonding of the saw blade force cutter 2 to the carton blank 1 is performed one after another. The saw blade cutter 2 glued to the carton blank 1 in this way is glued almost entirely with adhesive 6, as shown in Fig. There is no area (end 2c).
次に、 図 1 ( c ) に示すように、 カートンブランク 1に接着剤によって接着し た鋸刃カッター 2の両端を超音波ホーン 2 0を用いて超音波シールする。 この動 作は図 3、 図 4に示す超音波シール装置で行う。 すなわち、 図 3、 図 4において、 1 5はカートンブランク 1を搬送する 1 ^ローラ、 1 6は所定位置に停止した力 一トンブランク 1の鋸刃力ッター 2の両端の下方に位置するように設けられた一 対のアンビル、 1 7は定位置に設けられた装置フレーム、 1 8はその装置フレー ム 1 7に固定された支持台、 1 9は支持台 1 8に上下に移動可能に^^されたホ ーン^具、 2 0はホーン^具 1 9に取り付けられた超音波ホーンであり、 コ ンバ一夕 2 0 a、 ブースター 2 0 b、 ホーン 2 0 c等を備えている。 2 2はホー ン^具 1 9を上下動させるエアシリンダである。 Next, as shown in FIG. 1 (c), both ends of the saw blade cutter 2 bonded to the carton blank 1 with an adhesive are ultrasonically sealed using an ultrasonic horn 20. This operation is performed by the ultrasonic sealing device shown in Figs. That is, in FIGS. 3 and 4, 15 is a 1 ^ roller for transporting the carton blank 1, 16 is a force stopped at a predetermined position, and 16 is a force stopped at a predetermined position. A pair of anvils provided, 17 is an equipment frame installed in a fixed position, and 18 is an equipment frame. The support 17 is fixed to the support 17, 19 is a horn that can be moved up and down on the support 18, and 20 is an ultrasonic horn attached to the horn 19. , A combo 20a, a booster 20b, and a horn 20c. 22 is an air cylinder for moving the horn 19 up and down.
ここで、 超音波ホーン 2 0は、 所定位置に停止したカートンプランク 1に貼り 付けられている鋸刃力ッター 2の両端をそれぞれシールしうるよう 2偭設けられ ている。 また、 その超音波ホーン 2 0は、 ホーン 2 0 cの TS (超音波シールを 行う面）が、図 5に 2点鎖線で示すように、 鋸刃カッター 2の端部 2 cおよびそ の少し外側を押圧するように配置されている。 ホーン 2 0 cの T¾の大きさは、 鋸刃カッター 2の端部 2 cの 5〜2 0 mmg¾の長さ部分、 好ましくは 1 0 mm 程度の長さ部分をシールしうるように定められている。 ここで、 超音波ホーン 2 0による鋸刃カッター 2の端部 2 cのシーノレ長さが 5 mmよりも短いと、 超音 波シールの効果が小さくて鋸刃カッター 2の端部 2 cが剥がれやすくなり、一方、 2 0 mmよりも長くなると超音波シールの効果はあまり向上しないにも係わらず 超音波ホーン 2 0が^化し好ましくない。 このため、上記の範囲が好ましい。 シーノレ条件としては、 例えば、 シール面積 1 O x l 5 mmに対して、 2 0 K H z で 3 k gZ c m2 の圧力で、 0. 1秒程度の発振でよい。 Here, two ultrasonic horns 20 are provided so as to be able to seal both ends of the saw blade force cutter 2 attached to the carton plank 1 stopped at a predetermined position. In addition, the ultrasonic horn 20 has a TS (surface on which ultrasonic sealing is performed) of the horn 20c, as shown by a two-dot chain line in FIG. It is arranged to press the outside. The size of T¾ of the horn 20c is determined so that the end portion 2c of the saw blade cutter 2 can seal a length of 5 to 20 mmg¾, preferably a length of about 10 mm. I have. Here, if the length of the edge 2c of the saw blade cutter 2 by the ultrasonic horn 20 is shorter than 5 mm, the effect of the ultrasonic seal is small and the end 2c of the saw blade cutter 2 peels off. On the other hand, if the length is longer than 20 mm, the ultrasonic horn 20 is undesirably reduced because the ultrasonic sealing effect is not so much improved. Therefore, the above range is preferable. For example, the shearing condition may be an oscillation of about 0.1 second at a pressure of 3 kgZcm2 at 20 KHz with respect to a sealing area of 1 Oxl 5 mm.
この超音波シール装置による動作は次のように行われる。 図 3、 図 4において、 上面に鋸刃力ッター 2を接着したカートンブランク 1カ<送られてきて、 所定位置 に位置決めされて固定される。 次に、 エアシリンダ 2 2, 2 2カ^して超音波 ホーン 2 0 , 2 0を鋸刃カッター 2の両端部 2 cにそれぞれ押し当て、 超音波シ ールする。 所定時間の超音波シールを行った後、 超音波ホーン 2 0, 2 0が上昇 し、 カートンブランク 1は次の工程に送り出され、 新たなカートンブランク 1が 送り込まれる。 以下、 同様な動作を繰り返すことにより、 カートンブランク 1に 対する鋸刃カッター 2の両端部 2 cのシールが行われ、 図 5に示すように、 接着 剤 6の存在しな tゝ部分を鋸刃力ッター 2の端部が力一トンブランク 1に強く溶着 される。 なお、锯刃カッター 2の鋸刃 2 aは、 カートンブランク 1に接着しては いけないが、 カートンブランク 1のうち鋸刃 2 aの下に位置する領域 1 bには剥 離性の O Pニスを塗布しており、 超音波シールを行っても溶着することはない。 もし、溶着する恐れがある場合には、 アンビル 1 6が鋸刃 2 aの下を外れるよう にしておけばよい。 The operation of the ultrasonic sealing device is performed as follows. In FIGS. 3 and 4, one carton blank with a saw blade force cutter 2 adhered to the upper surface is sent in, and is positioned and fixed at a predetermined position. Next, the ultrasonic horns 20, 20 are pressed against both ends 2 c of the saw blade cutter 2 by air cylinders 22, 22 to perform ultrasonic sealing. After performing the ultrasonic sealing for a predetermined time, the ultrasonic horns 20 and 20 are raised, the carton blank 1 is sent out to the next step, and a new carton blank 1 is sent in. Thereafter, by repeating the same operation, the both end portions 2c of the saw blade cutter 2 are sealed to the carton blank 1, and as shown in FIG. The end of the saw blade power cutter 2 is strongly welded to the blank 1 at the t ゝ portion where the agent 6 does not exist. The saw blade 2a of the blade cutter 2 must not be glued to the carton blank 1, but a peelable OP varnish is used in the area 1b of the carton blank 1 located below the saw blade 2a. It is applied and does not weld even if ultrasonic sealing is performed. If there is a risk of welding, the anvil 16 should be kept under the saw blade 2a.
上記した工程を経たカートンブランク 1は、 その後、 次の工程に送ら 図 7 に示すように箱状のカートン 1 Aに組み立てられ且つ内部にロール伏のアルミホ ィルゃラッピングフィルムが収容され、 使用される。 ここで、鋸刃カッター 2は、 そのまま全長に渡つて接着剤 6によってカートンブランク 1に接着した後、剥が れやすい両端部 2 cを超音波シールしているので、 鋸刃カッター 2の両端部 2 c の接着が確実であり、 ^中に剥がれたり、 浮き上がったりすることなく、長時 間に渡って安定して できる。 しかも、 鋸刃カッター 2の両端部 2 cは超音波 シール時の発熱により、 含浸樹脂分が溶融し、 更に圧力力かかるため密度カ ま つて ¾¾¾カ<上がっており、鋸刃両端部の切 »H4が向上している。 このため、 アル ミホイルゃラッビングフィルム等の切断に際し、 切断初期に最も力のかかる両端 部 2 cの切れ味が良いため、 フィルムの切断が容易である。鋸刃カッター 2の切 れ味を確認するため、 引張り試験機に、 X Y Z軸方向にそれぞれ 4 5、 4 5、 3 0度の角度を付けて鋸刃カッター付のカートンをセットし、 フィルムを一 度 （5 0 0 mmZ分） で引っ張り、 切断時の最大荷重 （切れ始めの最大荷重） を 測定したところ、通^ ¾着部では 3 0 8 gであるのに対し、超音波シール部 （超 音波シール条件は、 シール 1 0 x l 5 mm、 発振周波数 2 0 K H z、圧力 3 k g/ c m2 、 発振時間 0. 1秒） では 2 2 5 gとなっており、 切れ味の良い ことカ《¾¾できた。 The carton blank 1 that has undergone the above-mentioned steps is then sent to the next step, assembled into a box-shaped carton 1A as shown in Fig. 7, and a roll-down aluminum foil wrapping film is housed inside and used. You. Here, the saw blade cutter 2 is bonded to the carton blank 1 with the adhesive 6 over the entire length as it is, and then the both ends 2 c that are easily peeled off are ultrasonically sealed. The bonding of c is reliable, and it can be stable for a long time without peeling or floating inside. In addition, the impregnated resin is melted by the heat generated during ultrasonic sealing at both ends 2 c of the saw blade cutter 2, and the pressure is further increased due to the application of pressure. H4 has improved. For this reason, when cutting aluminum foil-rubbing film, etc., the film is easy to cut because both ends 2c where the most force is applied at the beginning of cutting are sharp. To check the sharpness of the saw blade cutter 2, set a carton with a saw blade cutter on the tensile tester at 45, 45, and 30 degrees in the X, Y, and Z directions, respectively, and remove the film. When the maximum load at the time of cutting (maximum load at the beginning of cutting) was measured, the weight was 308 g at the through-bonded part, whereas the ultrasonic seal part (ultra The sonic sealing conditions are as follows: seal 10 xl 5 mm, oscillation frequency 20 KHz, pressure 3 kg / cm 2 , oscillation time 0.1 sec. did it.
なお、上記 例では、 鋸刃力ッター 2を接着剤 6でカートンブランク 1に接 着した後、 その箱刃カッター 2の両端部 2 cのみを超音波シールしている力 必 要に応じ、両端部 2 cのみならず、 その中間の適当な小領域を超音波シールとし てもよい。 また、上記 Hife例では真っ直ぐな鋸刃カッター 2を用いた場合を説明 したが、 図 9に示すように、 全体が浅い V字状をなした鋸刃カッター 2 Aをカー トンプランク 1の掩^ 1 aの ¾®に貼り付けて用いる場合にも本発明は適用可 能である。 すなわち、 このような形 の鋸刃カッター 2 Aを用いる場合にも、 そ のほぼ全長を接着剤によってカートンプランク 1に貼り付けた後、鋸刃カッター 2 Aの両端 （二点鎖線 2 5で示す領域） を超音波シールすればよい。 In the above example, the saw blade force cutter 2 is connected to the carton blank 1 with the adhesive 6. After mounting, the ultrasonic sealing force is applied only to both ends 2 c of the box blade cutter 2 .If necessary, not only both ends 2 c but also an appropriate small area in the middle can be ultrasonically sealed. Good. Also, in the above Hife example, the case where the straight saw blade cutter 2 was used was described, but as shown in Fig. 9, the whole saw blade cutter 2A having a shallow V-shape was covered with a carton plank 1 cover. The present invention is also applicable to the case where the present invention is used by attaching it to the ¾® of 1a. That is, even when using the saw blade cutter 2 A having such a shape, after attaching almost the entire length to the carton plank 1 with an adhesive, both ends of the saw blade cutter 2 A (indicated by a two-dot chain line 25). Region) may be ultrasonically sealed.
更に、 鋸刃カッター 2 Aを用いる場合、 そのほぼ全長を接着剤によってカート ンブランク 1に貼り付けた後、鋸刃力ッター 2 Aの両端部 （二点鎖線 2 5で示す 領域） を超音波シールすると共に、 V字の尖端の部分 （二 線 2 6で示す V字 部） を超音波シールしてもよい。 このようにすると、 鋸刃カッター 2 Aの剥がれ やすい両端部 2 5および V字部 2 6の確実な接着を確保でき、 長期間に渡って一 層安定して使用できる。  Furthermore, when using the saw blade cutter 2A, the entire length of the saw blade cutter 2A is attached to the carton blank 1 with an adhesive, and then both ends of the saw blade force cutter 2A (the area indicated by the two-dot chain line 25) are ultrasonically sealed. At the same time, the tip of the V-shaped part (the V-shaped part indicated by two-lined line 26) may be ultrasonically sealed. In this way, the two ends 25 and the V-shaped part 26 of the saw blade cutter 2 A, which are easily peeled, can be reliably bonded, and can be used more stably over a long period of time.
なお、 £Lhの Hlfe例では、 鋸刃カッター 2の両端部 2 c、 或いは鋸刃カッター 2 Aの両端部 2 5および V字部 2 6を超音波シールした場合を説明したが、 超音 波シールに代えてヒートシールを用いてもよい。  In the case of Hlfe of £ Lh, the case where both ends 2 c of the saw blade cutter 2 or both ends 25 and the V-shaped portion 26 of the saw blade cutter 2 A are ultrasonically sealed has been described. A heat seal may be used instead of the seal.
説明したように、 本 明によれば、 鋸刃カッターを、 そのほぼ全長に渡 つて接着剤によってカートンブランクに接着した後、 少なくとも両端部を超音波 シールまたはヒートシールする構成としたことにより、 鋸刃カッターの剥がれや すい両端部を確実に且つ強く接着することができ、 使用中に剥がれるということ がなく、 し力、も、 鋸刃カッターの両端部は単に小面積を接着すればよいので、 そ の接着に用いる超音波シール装置またはヒートシール装置は小出力の、 簡単な構 造のものでよく、 しかも確実な接着力河能であるという効果を有している。 更に、 鋸刃カッターの両端部を超音波シールまたはヒートシールしたことにより、 その 部分が加圧加熱されて樹脂密度か Ί¾まり、 このため鋸刃力ッ夕一によつてラッピ ングフィルム等を切断する際にもっとも力のかかる両端部の切 »ί¾が向上し、 切 断力容易となるという効果も得られる。 As described above, according to the present invention, the saw blade cutter is bonded to the carton blank with an adhesive over almost the entire length thereof, and then at least both ends are ultrasonically sealed or heat-sealed. Both ends of the blade cutter can be securely and strongly adhered to each other, so that they do not come off during use. The ultrasonic sealing device or heat sealing device used for the bonding may have a small output and a simple structure, and has an effect that the bonding force is reliable. In addition, by ultrasonically sealing or heat sealing both ends of the saw blade cutter, The part is heated under pressure and the resin density is reduced, so that when cutting wrapping film, etc., with a saw blade force, the cutting force at both ends where the most force is applied is improved, and the cutting force is increased. The effect that it becomes easy is also obtained.
また、 樹脂含浸紙で雜刃カッターを構成したことにより、 含浸樹脂による溶着 性を利用でき、 換言すれば、 樹脂含' にポリエチレンコート等の二 MO!を行 うことなく、超音波シールやヒートシールを行うことができ、 このため、 超音波 シールやヒートシールを用いてカートンプランクに接着しうる鋸刃カッターを安 価に製造でき、 しかも、樹脂含浸紙は吸湿性がほとんど無いため、 中におい て吸湿して劣化したり、 剥がれるということがないという効果を有している。  In addition, because the blade is made of resin-impregnated paper, the weldability of the impregnated resin can be used.In other words, ultrasonic sealing and heat-sealing can be performed without applying two MO! Sealing can be performed, so that a saw blade cutter that can be adhered to carton plank using ultrasonic sealing or heat sealing can be manufactured at low cost, and because resin-impregnated paper has almost no hygroscopicity, It has the effect of not deteriorating or peeling off due to moisture absorption.
