明細書 Specification
段ボ一ルの製造方法及び段ポ―ルの製造装置 技術分野 TECHNICAL FIELD The present invention relates to a method for manufacturing a step ball and an apparatus for manufacturing a step ball.
この発明は、 一般的には段ボールの製造方法及び段ボールの製造装置に関する ものである。 The present invention generally relates to a cardboard manufacturing method and a cardboard manufacturing apparatus.
さらに具体的には、 この発明は中芯原紙に傾斜した段を有する段ボールの製造 方法、 及び、 幅方向に対して傾斜した段を有する片面段ボールや、 貼り合わせた 段付中芯相互の段がクロスした状態の複両面段ボールを製造する方法及び装置に 関するものである。 背景技術 More specifically, the present invention relates to a method for producing a corrugated cardboard having a step inclined on a core base paper, and a single-sided cardboard having a step inclined with respect to the width direction, and a step between the laminated stepped cores. The present invention relates to a method and an apparatus for producing a double-faced double-faced cardboard in a crossed state. Background art
普通の段ボールは、 段付中芯の段が幅方向に沿って形成されているので、 幅方 向の垂直荷重に対する圧縮強度は大きレ、が、 長さ方向の垂直荷重に対する圧縮強 度は極めて小さい。 したがって、 このような段ボールを使用した段ボール箱は、 底面と天面、 両方の長さ面、 両方の幅面のそれぞれに対する垂直荷重への圧縮強 度に大きな差が生じるために、 物品を包装した段ボール箱を積み上げる際、 縦積 み (幅面が上下に位置する状態で積み上げること) したり横積み (長さ面が上下 に位置する状態で積み上げること) したりすることができない。 Since ordinary corrugated cardboard has a stepped core formed along the width direction, the compressive strength against vertical load in the width direction is large, but the compressive strength against vertical load in the length direction is extremely high. small. Therefore, a cardboard box using such cardboard has a large difference in the compressive strength to the vertical load on each of the bottom surface and top surface, both length surfaces, and both width surfaces. When stacking boxes, it is not possible to stack vertically (stacking with the width side up and down) or side by side (stacking with the length side up and down).
このような課題を解決するために、 幅方向に対して斜めの段を有する段ボール の製造方法が提案されている。 In order to solve such a problem, a method of manufacturing a corrugated cardboard having a step oblique to the width direction has been proposed.
斜め段を有する段ボールの製造方法及び製造装置には、 例えば特開昭 5 4一 7 6 3 9 3号公報に記載されているの発明がある。 A method and an apparatus for manufacturing a corrugated cardboard having an oblique step include, for example, an invention described in Japanese Patent Application Laid-Open No. 54-76393.
前記公報に記載されている段ボールの製造方法及び装置は、 相互に嚙み合う一 対の段ロールの段成形歯を螺旋状(ヘリカル) に形成している。 そして、 段ロー ルの嚙合線に対して側方へ傾斜した挿入角を形成した状態で中芯原紙を前記段口 ールに挟み込ませ、 前記段ロ-ルの嚙み合い線に対する中芯原紙の挿入角を調整 することによって、 段ロールから繰り出される段付中芯を段ロールの嚙合線に対 して直角方向へ走行させるように構成している。
また、 この従来の段ボールの製造方法及び装置では、 製造された片面段ボール の移送方向を逆方向へ変換する場合、 成形された段の方向を無視して方向変換す ることができるように、 曲率の大きい円弧状のガイドを使用している。 In the corrugated cardboard manufacturing method and apparatus described in the above publication, the corrugated teeth of a pair of corrugated rolls are formed in a spiral shape (helical shape). Then, the core base paper is sandwiched between the step rolls while forming an insertion angle inclined sideways with respect to the line of connection of the step roll, and the core base paper with respect to the connection line of the step roll is formed. By adjusting the insertion angle of the step roll, the stepped core unwound from the step roll is caused to travel in a direction perpendicular to the line of connection of the step roll. Further, in the conventional method and apparatus for manufacturing corrugated cardboard, when the transport direction of the manufactured single-faced corrugated cardboard is changed to the opposite direction, the curvature is changed so that the direction of the formed corrugated cardboard can be ignored ignoring the direction of the formed corrugated cardboard. Uses a large arc guide.
中芯原紙に斜め段を成形する場合、 中芯原紙はその幅方向と長さ方向に収縮す るが、 前述した従来の斜め段を有する段ボールの製造方法及び装置は、 以下のよ うな欠点がある。 When the oblique step is formed on the core base paper, the core base paper shrinks in the width direction and the length direction, but the above-described conventional method and apparatus for manufacturing corrugated cardboard having oblique steps have the following disadvantages. is there.
その欠点の一"" ^ま、 段ロールの段成形歯がヘリカルに成形されているので、 中 芯原紙を回転する両段ロール間に挟み込んだ場合、 中芯原紙は段口ールによつて 挟まれている部分が当該段ロールの嚙合線に沿って一気に収縮する。 この一気の 収縮により、 中芯原紙の段ロールで挟まれている部分が破れるため、 段の成形は 不可能ないし極めて困難であることである。 One of the drawbacks is that, because the corrugated teeth of the corrugated roll are formed helically, if the corrugated core paper is sandwiched between both rotating corrugated rolls, the corrugated core paper will be The sandwiched portion contracts at a stretch along the joining line of the step roll. This sudden shrinkage breaks the part of the core paper that is sandwiched by the step rolls, making it impossible or extremely difficult to form the steps.
その欠点の他の 3は、 ヘリ力ノレな段成形歯を精密に形成するのは、 ロールの 軸心と平行な段成形歯が成形された普通の段口ールょりはるかに高価になるので 、 製造設備が高価になることである。 Another drawback is that the precise formation of the helicopter stepped teeth is much more expensive than the ordinary stepped teeth formed with the stepped teeth parallel to the roll axis. Because the manufacturing equipment is expensive.
この発明の目的は、 中芯原紙の幅方向に対して侯斜した段をより円滑に、 しか もより安価に成形することができる段ボールの製造方法を提供することにある。 この発明の他の目的は、 斜め段を有する片面段ボ一ルゃ両面段ボールをより円 滑にかつ安価に製造することができる段ボールの製造方法及び製造装置を提供す る とにのる。 発明の開示 An object of the present invention is to provide a method of manufacturing a corrugated cardboard, which can form a step inclined in the width direction of a core base paper more smoothly and at a lower cost. It is another object of the present invention to provide a cardboard manufacturing method and a cardboard manufacturing method capable of manufacturing a single-sided cardboard having a diagonal step and a double-sided cardboard more smoothly and inexpensively. Disclosure of the invention
この発明による段ポールの製造方法の一つは、 前述の目的を達成するために、 一定幅の中芯原紙を連続的に繰り出しながら、 段成形歯が軸方向に沿って形成さ れた一対の段ロールの間に、 当該段ロールの嚙合線に対して側方へ 1 5〜8 4。 の挿入角を形成する状態で前記中芯原紙を挟み込ませることにより、 幅方向に対 して傾斜した段を有する段付中芯を製造するように構成している。 One of the methods for manufacturing a step pole according to the present invention is as follows. In order to achieve the above-described object, a pair of stepped teeth formed along the axial direction while continuously feeding out a constant-width base core paper. Between the corrugated rolls, 15 to 84 laterally to the joint line of the corrugated roll. By inserting the core base paper in a state where the insertion angle is formed, a stepped core having a step inclined with respect to the width direction is manufactured.
段付中芯を前述のように製造すると、 中芯原紙が一対の段ロールに順次挟み込 まれるとき、 当該中芯原紙は雨段ロールの嚙合線に沿う部分では縮まらず、 最初 に雨段口一ルに挟まれる幅方向の側部から他方の側部へと順次縮まる。 したがつ
て、 中芯原紙が破れることなく当該中芯原紙へ円滑に斜め段が形成される。 When the stepped core is manufactured as described above, when the core base paper is successively sandwiched between a pair of step rolls, the core base paper does not shrink at a portion along the joining line of the rain step roll, and firstly the rain step is performed. It gradually shrinks from the side in the width direction sandwiched by the mouth to the other side. According to Thus, the oblique step is smoothly formed on the core base paper without breaking the core base paper.
両段ロールの嚙合線に対する中芯原紙の挿入角は、 製造しょうとする段付中芯 の段の傾斜角に基づいて選択する。 The insertion angle of the core base paper with respect to the joining line of both rolls is selected based on the inclination angle of the step of the stepped core to be manufactured.
ただし、 中芯原紙に傾斜した段を成形する場合、 中芯原紙は長さ方向のみなら ず幅方向にも収縮するので、 段ロールの嚙合線に対する中芯原紙の挿入角と、 製 造される段付中芯の段の傾斜角とは一致せず、 前者より後者の方が小さくなる。 両者の相違は、 主として形成する段のサイズ (A段, B段, C段及び E段の別) によって異なる。 However, when an inclined step is formed on the core base paper, the core base paper shrinks not only in the length direction but also in the width direction, so the insertion angle of the core base paper with respect to the joint line of the step roll is produced. The angle of inclination of the stepped core does not match, and the latter is smaller than the former. The difference between the two depends mainly on the size of the steps to be formed (A, B, C and E).
前述の段ボールの製造方法においては、 中芯原紙が段ロールに挟み込まれる直 前に、 最初に設定した挿入角が変化しないように当該中芯原紙の姿勢を制御する のが好ましい。 その理由は、 段ロールの嚙合線に対して横方向に傾斜した挿入角 を形成する状態で当該段ロールへ中芯原紙を連続して挿入した場合、 その中芯原 紙が、 段口 -ルの嚙合線の部分にぉ 、て当該嚙合線に対し直角になる方向へ移動 し易いことによる。 In the corrugated cardboard manufacturing method described above, it is preferable to control the posture of the core base paper so that the insertion angle initially set does not change immediately before the core base paper is sandwiched between the corrugated rolls. The reason is that, when the core base paper is continuously inserted into the corresponding step roll in a state where the insertion angle is inclined in the horizontal direction with respect to the joining line of the step roll, the core base paper is This is due to the fact that it is easy to move in the direction perpendicular to the joint line.
前述のように製造された段付中芯を、 当該段付中芯の段が前記段ロールと平行 する状態で連続的に移送しながら、 当該段付中芯の一方の面の段頂へ連続的に糊 付けし、 次いで、 前記段付中芯の糊付けされた段頂へライナを連続的に貼り合わ せることにより、 斜めの段を有する片面段ボ一ルが製造される。 While the stepped core manufactured as described above is continuously transferred while the step of the stepped core is parallel to the step roll, the stepped core is continuously transferred to the step top on one surface of the stepped core. A single-sided stepped ball having an oblique step is manufactured by continuously laminating the liner to the stepped core of the stepped core.
段付中芯を移送する途中で、 当該段付中芯へ糊付けしその段頂へライナを張り 合わせる工程では、 前記成形口一ルの段成形歯のピッチで当該段成形歯より低レ、 歯丈の案内歯が形成されたライダロールにより、 前記案内歯相互の間に前記段付 中芯の一方の面の段が挿入された状態で移送するのが好ましい。 In the process of gluing the stepped core and attaching the liner to the top of the stepped core during the transfer of the stepped core, the pitch is lower than the stepped tooth at the pitch of the stepped tooth of the forming port. It is preferable that the transfer is performed in a state in which the step of the one surface of the stepped core is inserted between the guide teeth by a rider roll formed with length guide teeth.
また、 前述の方法によって製造された一の片面段ボールを、 段頂が上方へ向く 状態で一方から連続して送り出し、 当該一の片面段ボールを段の方向に沿って曲 げながら段頂が下方を向く状態に連続して方向変換し、 この方向変換の工程の途 中又は前記方向変換後において、 前記一の片面段ボールの段頂に連続して糊付け し、 前述の方法によって製造された他の片面段ボールを、 段頂が上方に向き、 か つ当該片面段ボールの段が前記一の片面段ボールの段に対して逆方向に傾斜した 状態で他方から連続して繰り出しながら、 当該他の片面段ボールを前記一の片面
段ボールの下面と順次重ね合わて、 両片面段ボールの段頂相互を連続して接着す れば、 接合された段付中芯の段相互が所定の角度で交差した複両面段ボールが製 造される。 In addition, one single-faced cardboard manufactured by the above-described method is continuously sent out from one side with the top facing upward, and the one-sided cardboard is bent downward while bending the single-sided cardboard along the direction of the step. In the middle of this direction change step or after the direction change, the direction is continuously glued to the top of the one-sided corrugated cardboard, and the other one side manufactured by the method described above. The other single-sided corrugated cardboard is continuously fed from the other while the corrugated cardboard is upwardly directed and the single-sided corrugated cardboard is inclined in the opposite direction with respect to the one single-sided corrugated cardboard. One side When the tops of both single-sided cardboards are successively adhered to each other by successively overlapping the lower surface of the cardboard, a double-sided corrugated cardboard in which the steps of the joined stepped cores intersect at a predetermined angle is manufactured.
この発明による段ボールの製造方法の他の一つによれば、 一定幅の中芯原紙を 一定間隔に力ットすることにより、 平行四辺形の一定サイズの中芯片を製造する 工程と、 この中芯片を、 互いに平行で直線伏に段成形歯が形成された一対の段成 形機の間に、 当該中芯片のー側辺が当該段成形機の段形成歯に対して側方へ 1 5 〜8 4 ° の挿入角を形成するように挟み込ませることにより、 当該中芯片の幅方 向に対して傾斜した段を有する段付中芯を製造する工程とを含む段ボールの製造 方法が提供される。 According to another one of the methods for manufacturing a cardboard according to the present invention, a step of manufacturing a parallelogram-shaped core piece of a constant size by pressing a core paper having a constant width at a constant interval; The core piece is placed between a pair of step forming machines in which the step forming teeth are formed in parallel with each other in a straight line, and the side of the core piece is lateral to the step forming teeth of the step forming machine. A step of manufacturing a stepped core having a step inclined with respect to the width direction of the core piece by sandwiching the core piece so as to form an insertion angle of about 84 °. You.
段付中芯をこのように製造すると、 中芯片が一対の段ロールに順次挟み込まれ るとき、 当該中芯片は段成形機の段成形歯に沿う部分では縮まらず、 最初に段成 形機に挟まれる幅方向の側部から他方の側部へと順次縮まる。 したがって、 中芯 片が破れることなく当該中芯辺へ円滑に斜め段が形成される。 When the stepped core is manufactured in this way, when the core piece is successively sandwiched between a pair of step rolls, the core piece does not shrink at a portion along the step forming teeth of the step forming machine, and is first formed by the step forming machine. It gradually shrinks from the side in the width direction to the other side. Therefore, the oblique step is smoothly formed on the side of the core without breaking the core piece.
段成形機の段成形歯に対する中芯原紙の挿入角は、 製造しょうとする段付中芯 の段の煩斜角に基づレ、て選択する。 The insertion angle of the core base paper into the step forming teeth of the step forming machine is selected based on the oblique angle of the step of the stepped core to be manufactured.
ただし、 段成形機の段成形歯に対する中芯片の幅方向の一側辺の挿入角と、 製 造される段付中芯の幅方向に対する段の傾斜角とは一致せず、 前者より後者の方 が小さくなる。 両者の相違は、 主として形成する段のサイズ(A段, B段, C段 及び E段の別) によって異なる。 However, the insertion angle of one side in the width direction of the core piece with respect to the step forming teeth of the step forming machine does not match the inclination angle of the step with respect to the width direction of the stepped core to be manufactured. Is smaller. The difference between the two depends mainly on the size of the steps to be formed (A, B, C and E).
前記中芯片の一の対角を鋭角に形成するとともに、 この中芯片を一の鋭角の部 分から前記一対の段成形機の間に挟み込ませ、 かつ、 この挟み込みのときの前記 挿入角と前記鋭角とを適切に選択すれば、 方形の段付中芯が製造される。 One diagonal of the core piece is formed at an acute angle, and the core piece is sandwiched between the pair of step forming machines from one acute angle portion, and the insertion angle and the acute angle at the time of this sandwiching are formed. With appropriate choices, a square stepped core is produced.

And a plurality of cam pieces including a plurality of cam pieces closely arranged in a state where the stepped teeth face the molding surface of the molding table. The core piece is sucked and held on the molding surface of the molding table, and each of the cam pieces is sequentially inserted from one end of the force piece in the parallel direction to the other end between the step molding teeth of the molding table. According to this, a stepped core having a step inclined in the width direction can be manufactured.

BEST MODE FOR CARRYING OUT THE INVENTION
先ず、 この発明による段ボールの製造方法のうち、 ミルロールスタンドから操 り出される帯状の中芯原紙に対して、 斜めの段を連続的に成形するための実施例 を説明する。 First, in the method for manufacturing corrugated cardboard according to the present invention, an embodiment for continuously forming an oblique step on a band-shaped core base paper fed from a mill roll stand will be described.
第 1図の符合 2 0は図示されていない加熱手段を有する上下一対の段ロールで あり、 1 3は吸引機能を有するコンペャからなる姿勢制御手段である。 一対の段 ロール 2 0には、 それぞれ軸心と平行な図示されていない段成形歯が形成されて いる。 Reference numeral 20 in FIG. 1 denotes a pair of upper and lower step rolls having a heating means (not shown), and reference numeral 13 denotes a posture control means comprising a conveyor having a suction function. Each of the pair of step rolls 20 has step forming teeth (not shown) parallel to the axis.
図示されていないミルロールスタンドから繰り出される帯状の中芯原紙 1は、 姿勢制御手段 1 3によって直進するように姿勢制御されながら、 段ロール 2 0の 嚙合線 2 1に対して側方へ約 7 4 0 の挿入角 θ 1を形成するように段ロール 2 0 へ挟み込まれる。 The belt-shaped core base paper 1 unwound from a mill roll stand (not shown) is controlled by the posture control means 13 so as to move straight, while being approximately 7 laterally to the joining line 21 of the step roll 20. sandwiched to corrugating roll 2 0 to form an insertion angle theta 1 of 4 0.
段ロール 2 0へ挟み込まれた中芯原紙 1は、 当該段ロール 2 0によって、 長さ 方向に対し約 6 5 ° (幅方向に対しては 2 5 ° ) の傾斜角 Θ 2 (又は繰り出し角 ) をもつ段 1 1 (A段) が連続的に形成されつつ繰り出されることにより、 段付 中芯 1 0が連続して製造される。 The core paper 1 sandwiched between the step rolls 20 is inclined by about 65 ° in the length direction (25 ° in the width direction) Θ 2 (or the feeding angle) by the step rolls 20. ) Are continuously formed and fed out while continuously forming the stepped core 10.
中芯原紙 1は、 段ロール 2 0によって段 1 1が形成されるとき、 長さ方向へ収
縮するとともに幅方向にも収縮する。 The core base paper 1 is collected in the length direction when the step 11 is formed by the step roll 20. It shrinks as well as in the width direction.
中芯原紙 1は段ロール 2 0に対して斜め方向から挟み込まれるので、 中芯原紙 1が幅方向に収縮するときは、 挿入角 0 1が形成されている方の側部から順次他 方の側部の方向 (図において下側部から順次上側部の方向) へ収縮する。 Since the core paper 1 is sandwiched from the oblique direction with respect to the step roll 20, when the core paper 1 contracts in the width direction, the core paper 1 is sequentially inserted from the side where the insertion angle 01 is formed on the other side. It contracts in the direction of the side (in the figure, in order from the lower part to the upper part).
段成形時における中芯原紙 1の幅方向への収縮により、 段ロール 2から繰り出 される段付中芯 1 0は、 当該段ロール 2 0の嚙合線 2 1の位置から挿入角 0 1よ りもさらに約 9 ° 曲がった状態で繰り出される。 その結果、 段付中芯 1 0の長さ 方向に対する段 1 1の傾斜角 0 2は、 前述のように約 6 5 ° ( 7 4 ° — 9。 ) に なる。 Due to the shrinkage of the core base paper 1 in the width direction during the step forming, the stepped core 10 fed from the step roll 2 moves from the position of the joint line 21 of the step roll 20 to the insertion angle 0 1. It is fed out with a further 9 ° turn. As a result, the inclination angle 02 of the step 11 with respect to the length direction of the stepped core 10 is about 65 ° (74 ° -9) as described above.
段 1 1の成形による、 中芯原紙 1の幅 w lから段付中芯 1 0の幅 w 2への収縮 率は、 長さ方向に対する傾斜角 0 2が 6 5。 の A段(3 0 0讓当たりの段数 3 4 ± 2、 段ピッチ長 8 . 3 3 3〜9 . 3 7 5鯽、 段高さ 4 . 5〜4 . 8鯽) の段付 中芯 1 0を製造する場合、 ほぼ 5 %前後である。 The shrinkage ratio from the width w l of the core base paper 1 to the width w 2 of the stepped core 10 by the molding of the step 11 is 65 at an inclination angle of 0 2 with respect to the length direction. A core (number of stages per 300 rows 3 4 ± 2, step pitch length 8.3 3 3 to 9.3 7 5 鯽, step height 4.5 to 4.8 鯽) When manufacturing 0, it is about 5%.
挿入角 θ 1と傾斜角 Θ 2の差、 段 1 1の成形による中芯原紙 1の輻 w 1から段 付中芯 1 0の幅 w 2への収縮率は、 成形される段 1 1のサイズ( A段, B段, C 段及び E段のいずれか、 又は段繰り率の差) 、 成形しょうとする段 1 1の傾斜角 0 2などによってそれぞれ異なっており、 これらは実験によって求めることがで きる。 The difference between the insertion angle θ1 and the inclination angle Θ2, the shrinkage from the radiation w1 of the core base paper 1 to the width w2 of the stepped core 10 due to the molding of the step 11 It differs depending on the size (one of A-stage, B-stage, C-stage, and E-stage, or the difference in repetition rate), and the inclination angle 0 2 of the stage 11 to be molded. I can do it.
ちなみに、 段 1 1が A段でその長さ方向に対する傾斜角 0 2が 4 5 ° の中芯原 紙 1 0を製造する場合、 挿入角 0 1は 5 8 ° 強、 中芯原紙 1の幅 w 1から段付中 芯 1 0の幅 w 2への収縮率は 1 4〜1 5 %である。 段 1 1を成形することによる 原紙幅の収縮率は、 中芯原紙 1の段ロール 2 0に対する挿入角 0 1の大きさに反 比例し、 原紙長さの収縮率は挿入角 6> 1の大きさに比例する。 By the way, when manufacturing the core base paper 10 in which the column 11 is the A stage and the inclination angle 0 2 with respect to the length direction is 2 45 °, the insertion angle 0 1 is more than 58 ° and the width of the core base paper 1 The shrinkage from w1 to the width w2 of the stepped core 10 is 14 to 15%. The shrinkage ratio of the base paper width due to the molding of step 11 is inversely proportional to the insertion angle 0 1 of the core base paper 1 with respect to the step roll 20, and the contraction rate of the base paper length is 6> 1 It is proportional to the size.
この実施例による段ボールの製造方法によれば、 中芯原紙 1が幅方向に収縮す るとき、 挿入角 0 1が形成されている方の側部から順次他方の側部の方向へ収縮 するので、 中芯原紙 1が破れることなく斜めの段 1 1を有する段付中芯 1 0が円 滑にかつ連続的に製造される。 According to the cardboard manufacturing method of this embodiment, when the core base paper 1 contracts in the width direction, it contracts sequentially from the side where the insertion angle 01 is formed toward the other side. Thus, the stepped core 10 having the oblique step 11 is produced smoothly and continuously without breaking the core base paper 1.
この実施例の方法で段ボールを製造する場合、 中芯原紙 1の段ロール 2 0によ つて嚙み合わされた部分は、 段ロール 2 0の嚙合線 2 1に対して直角になろうと
する方向、 すなわち第 1図の矢印 aの方向へ移動する場合があるので、 姿勢制御 手段 1 3は、 中芯原紙 1に対して矢印 aの反対方向へ付勢するように構成するの が好ましい。 次に、 前述の段成形方法を利用した段ボールの製造方法及び製造装置の実施例 を、 第 2図〜第 6図を参照しながら説明する。 In the case of manufacturing corrugated cardboard by the method of this embodiment, the portion joined by the corrugated rolls 20 of the core base paper 1 tends to be perpendicular to the joining line 21 of the corrugated rolls 20. In this case, the attitude control means 13 is preferably configured to urge the core base paper 1 in the direction opposite to the arrow a, since it may move in the direction of arrow a in FIG. .

As shown in FIG. 6, guide teeth 30 having the same pitch as the step forming teeth 24 of the lower step roll 23 are formed on the rider roll 3 and have a lower height than the step forming teeth 24.
この実施例におけるライダロール 3は、 前述のように下部段ロール 2 3と嚙み 合っているが、 下部段ロール 2 3と嚙み合わせずにその下方へ離れていても差し 支えない。 Although the rider roll 3 in this embodiment is engaged with the lower stage roll 23 as described above, the rider roll 3 may be separated from the lower stage roll 23 without being engaged therewith.
糊付け装置 4は、 前記アプリケ一夕ロール 4 0、 グルーパン 4 2及びドクター ロール 4 1などによって構成されている。 The gluing device 4 includes the apricot roll 40, glue pan 42, doctor roll 41, and the like.
前記両シングルフエーサ 2 , 2 aの段ロール 2 2, 2 2の軸心相互は、 それぞ れのシングルフヱ一サ 2, 2 aから送り出される片面段ボール 1 2 , 1 2 aが、
両シングルフエ—サ 2, 2 aの対向領域において上下に離れた状態で重なって交 差するように、 上方より見て所定の開き角 03を形成している。 The axial centers of the corrugated rolls 22 and 22 of the two single facers 2 and 2a are arranged so that the single-sided corrugated cardboards 12 and 12a sent from the respective single rollers 2 and 2a are: A predetermined opening angle 03 is formed when viewed from above so that the two single-fusers 2 and 2a overlap and cross each other in an opposing area in a vertically separated state.

Designed back and forth.
両シングルフエーサ 2, 2 aの図示されていないミルロールスタンドから操り 出される同じ幅 wlの中芯原紙 1, 1 aは、 それぞれ姿勢制御手段 1 3, 1 3に より、 各上下の段ロール 22, 23の間に直進するように移送され、 この上下の 各段ロール 22, 23に対して 74。 の挿入角 01で連繞的に挟み込まれる。 このようにして、 各上下の段ロール 22, 23の回転により、 長さ方向に対し て約 65° の傾斜角 02をもつ段 1 1, 1 1 a (A段) が成形された各段付中芯 1 0, 1 0 aがそれぞれ連続して製造される。 The core base papers 1 and 1a of the same width wl, which are driven from a mill roll stand (not shown) of both single facers 2 and 2a, are respectively controlled by the attitude control means 13 and 13 to form upper and lower step rolls. It is transported so as to go straight between 22, 23, and 74 for the upper and lower rolls 22, 23. Is inserted continuously at an insertion angle of 01. In this way, by rotating the upper and lower step rolls 22, 23, the steps 11, 1, 1a (step A) having an inclination angle 02 of about 65 ° with respect to the length direction are formed. The cores 10 and 10a are manufactured continuously.
前述のように繰り出される各段付中芯 1 0, 1 0 aは、 図示されていないフィ ンガにより、 それぞれの下部段ロール 23, 23及びライダロール 3, 3の回転 転方向へ追随して S字状に走行するようにガイドされる。 Each of the stepped cores 10 and 10a fed out as described above is driven by a finger (not shown) so as to follow the rotation direction of each of the lower step rolls 23 and 23 and the rider rolls 3 and 3, respectively. It is guided to run in a character shape.
前述のように、 ロール 23及びロール 3により段付中芯 1 0, 1 08を3字状 に走行させる場合、 段付中芯 1 0, 1 0 a及び中芯原紙 1, 1 aには、 第 2図の 矢印 bの逆方向へ移動する力が作用し易い。 したがって、 各下部段ロール 23, 23及び各ライダロール 3, 3には、 段付中芯 1 0, 1 0 aが繰り出される側の 面に、 姿勢制御手段 25, 3 1をそれぞれ設置し、 これらの姿勢制御手段 25, 3 1により、 S字状に走行している段付中芯 1 0, 1 0 aに対し第 2図及び第 4 図の矢印 bの方向へ適当な力で常時付勢している。 As described above, when the stepped cores 10 and 108 are run in a three-character shape by the rolls 23 and 3, the stepped cores 10 and 10 a and the core base papers 1 and 1 a The force that moves in the direction opposite to arrow b in FIG. 2 is likely to act. Therefore, each lower step roll 23, 23 and each rider roll 3, 3 are provided with attitude control means 25, 31 on the side where the stepped core 10, 10a is fed out, respectively. The posture control means 25, 31 at all times constantly urges the stepped cores 10, 10a running in an S-shape with an appropriate force in the direction of the arrow b in FIGS. 2 and 4. are doing.
この実施例の各姿勢制御手段 25は、 第 3図及び第 4図のように、 一対のブー リ 32, 33へ緊張して取り付けたゴム又は弾性を有する合成樹脂製のベルト 3 4で構成されている。 このベルト 34は、 第 4図のように矢印 bの方向へ先下が り状に傾斜し、 かつ、 各段付中芯 1 0を下部段ロール 23の表面にやや押しつけ るようになっており、 第 2図では反時計方向、 第 5図では時計方向へ回転するこ とにより、 段付中芯 1 0を矢印 bの方向へ付勢する。 As shown in FIGS. 3 and 4, each of the attitude control means 25 of this embodiment is constituted by a rubber or elastic synthetic resin belt 34 attached to a pair of burries 32, 33 under tension. ing. The belt 34 is inclined downward in the direction of arrow b as shown in FIG. 4 and slightly presses each stepped core 10 against the surface of the lower step roll 23. By rotating counterclockwise in FIG. 2 and clockwise in FIG. 5, the stepped core 10 is urged in the direction of arrow b.
他の姿勢制御手段 31, 3 1も同様にゴムベルトとブーリによって構成されて
いる。 The other attitude control means 31, 3 1 are also composed of rubber belts and burries. I have.
前述の姿勢制御手段 2 5 , 3 1は、 前述のような構成に代えて、 ゴムローラ又 は柔軟な合成樹脂のローラによつて構成することもできる。 The above-mentioned attitude control means 25, 31 may be constituted by a rubber roller or a roller of a flexible synthetic resin instead of the above-mentioned constitution.
下方へ S字走行するようにガイドされる段付中芯 1 0, 1 0 aの一方の段頂に は、 それぞれのアプリケ一夕ロール 4 0 , 4 0により連続的に糊付けされる。 こ のとき、 ライダロール 3の案内歯 3 0は第 6図のように歯丈が低く形成されてい るので、 糊が案内歯 3 0に付着しない。 One of the tops of the stepped cores 10 and 10a, which are guided so as to travel downward in an S-shape, is continuously glued by respective apricot rolls 40 and 40, respectively. At this time, since the guide teeth 30 of the rider roll 3 are formed to have a low tooth height as shown in FIG. 6, the glue does not adhere to the guide teeth 30.
他方、 各糊付け装置 4の下方には図示されていないミルロールスタンドがそれ ぞれ設置されており、 これらのミルロールスタンドからは、 テンションロール 5 3を経て段付中芯 1 0, 1 0 aと同じ幅のライナ 1 4, 1 4 aが前記段付中芯 1 0 , 1 0 aの移送速度とと同調して操り出される。 これらのライナ 1 4 , 1 4 a が、 プレスロール 5により段付中芯 1 0, 1 0 aの糊付けされた段頂に順次貼り 付けられて、 片面段ボール 1 2 , 1 2 aが連続的に製造される。 On the other hand, mill roll stands (not shown) are provided below the respective gluing devices 4. From these mill roll stands, stepped cores 10 and 10 a are provided via tension rolls 53. The liners 14 and 14a having the same width as the above are driven in synchronization with the transfer speed of the stepped cores 10 and 10a. These liners 14, 14 a are sequentially pasted on the stepped cores 10, 10 a to which the stepped cores 10, 10 a are glued by the press roll 5, and the single-sided cardboards 12, 12 a are continuously formed. Manufactured.
このように製造された片面段ボール 1 2, 1 2 aは、 段 1 1 , 1 1 aが上方を 向いた状態でそれぞれの移送装置 5 1 , 5 2により水平方向へ移送され、 一方の 片面段ボール 1 2が他方の片面段ボール 1 2 aより上方に位置する状態で両者の 交差部位 cに達する。 このとき、 片面段ボール 1 2 , 1 2 3の段1 1 , 1 1 aは 互レゝに逆方向に領斜している。 The single-sided cardboards 12 and 12a manufactured in this manner are transferred horizontally by the respective transfer devices 51 and 52 with the steps 11 and 11a facing upward. In a state where 12 is located above the other single-sided cardboard 12a, it reaches the intersection c between the two. At this time, the steps 11 and 11a of the single-sided cardboards 12 and 12 are mutually inclined in the opposite direction.
前記交差部位 cにおける両片面段ボール 1 2 , 1 2 aの間には、 上方の片面段 ボール 1 2の段 1 1に沿うように方向変換用のライダロール 6が設置されており 、 上方の片面段ボール 1 2は、 このライダロール 6により段 1 1に沿ってその移 送方向が逆方向へ変換される。 方向変換後の片面段ボール 1 2は、 段 1 1が他方 の片面段ボール 1 2 aの段 1 1 aと向き合って交差する状態で他方の片面段ボー ル 1 2 aと重なった姿勢になる。 Between the two single-sided cardboards 12 and 12a at the intersection portion c, a lider roll 6 for direction change is installed along the step 11 of the upper single-sided cardboard 12 and the upper single-sided cardboard The transfer direction of the cardboard 12 is changed by the rider roll 6 along the step 11 in the reverse direction. The one-sided corrugated cardboard 12 after the direction change has a posture in which the corrugated cardboard 11 overlaps the other single-sided corrugated cardboard 12a in a state where the corrugated cardboard 11 faces and intersects with the corrugated cardboard 11a of the other one-side corrugated cardboard 12a.
方向変換用のライダロール 6の近傍には、 下方を通過する片面段ボール 1 2 a と干渉しない位置に、 当該ライダロール 6に沿うアプリケ一夕ロール 6 1、 ドク 夕ロール 6 2及びグルーパン 6 3を含む糊付け装置 6 0が設置されている。 したがって、 一方の片面段ボール 1 2の段頂には、 当該段ボール 1 2の方向変 換中に T アプリケ一夕ロール 6 1により順次糊付けされる。 この片面段ボール
1 2は、 その方向変換によって下方の片面段ボール 1 2 aの上に順次重ねられ、 後方に設置されたプレスロール 5 0、 ヒーティングパート 5 4で下方の片面段ボ ール 1 2 aと貼り合わされることにより、 複両面段ボール 1 5が連続的に製造さ れる。 In the vicinity of the direction-changing rider roll 6, the applicator roll 61, the doctor roll 62, and the glue pan 63 along the rider roll 6 are positioned so as not to interfere with the single-sided cardboard 12 a passing below. A gluing device 60 is installed. Therefore, the one-sided corrugated cardboard 12 is sequentially glued to the corrugated top by the T-Apriquet overnight roll 61 while the direction of the corrugated cardboard 12 is changed. This one side cardboard 12 is sequentially stacked on the lower single-sided corrugated cardboard 12a by the change of direction, and is attached to the lower single-sided corrugated ball 12a by the press roll 50 and the heating part 54 installed at the rear. By being combined, the double-sided corrugated cardboard 15 is continuously produced.
第 7図には、 前述のように製造された複両面段ボール 1 5が拡大して例示され ている。 FIG. 7 is an enlarged view of the double-faced corrugated cardboard 15 manufactured as described above.
この複両面段ボール 1 5の各段付中芯 1 0 , 1 0 3の段1 1 , 1 1 aは、 その 幅方向 Wdに対する傾斜角 0 4と 0 5は共に 2 5 ° であり、 幅方向 Wdにおける 段 1 1 , 1 1 a相互の交差角は 5 0。 である。 In the double-sided corrugated cardboard 15, the stepped cores 10, 11 a of each of the stepped cores 10, 10 3 have an inclination angle of 0 4 and 0 5 with respect to the width direction Wd of 25 °. The crossing angle between steps 11 and 11a in Wd is 50. It is.
この複両面段ボール 1 5は、 相互の段頂の各交差部で互いに貼合された段 1 1 , 1 1 aによって形成される多数の菱形ないし平行四辺形が規則正しく網状に連 続する状態になり、 各段 1 1, 1 1 aが幅方向 Wdに対しても長さ方向 L dに対 しても多数の貼合部で突つ張り合い、 外力に対して有機的に協力し合っているの で、 幅方向 W d及び長さ方向 L dへの垂直荷重に対する圧縮強度は、 普通の復両 面段ボ一ルに比べてはるかに大きい。 This double-sided corrugated cardboard 15 is in a state where a large number of rhombuses or parallelograms formed by the steps 11 and 11a bonded to each other at the intersections of the steps are regularly connected in a mesh form. However, each of the steps 11 and 11a is stuck at a large number of bonding parts in both the width direction Wd and the length direction Ld, and organically cooperates with external force. The compressive strength against the vertical load in the width direction W d and the length direction L d is much larger than that of a normal double-sided stepped ball.
片面段ボール 1 2 , 1 2 a相互を貼り合わせるときに普通より強く加圧し、 第 8図のように段 1 1 , 1 1 aの交差部 1 6における段頂相互が圧縮された状態に すれば、 段ボールの幅方向及び長さ方向への垂直荷重に対する圧縮強度はより大 きくなる。 このように構成する場合、 交差部 1 6における段 1 1, 1 1 aの圧縮 率 (段高さに対する圧縮の割合) は、 5〜4 0 %の範囲であるのが好ましい。 複両面段ボール 1 5は、 段付中芯 1 0の段 1 1と段付中芯 1 0 aの段 1 1 aと が、 それぞれ段サイズを異にするように製造することができるほか、 幅方向 W d に対する傾斜角 0 4及び 0 5を異にするように製造することもできる。 第 9図及び第 1 0図は、 第 2図〜第 6図で示されている段ボール製造装置の一 部を変更した段ボール製造装置である。 When the single-sided corrugated cardboard 1 2, 1 2a is bonded to each other with a stronger pressure than usual, as shown in Fig. 8, if the tops at the intersection 16 of the steps 11, 11 a are compressed, However, the compressive strength of the cardboard against the vertical load in the width and length directions becomes larger. In such a configuration, the compression ratio (ratio of compression to the height of the step) of the steps 11 and 11a at the intersection 16 is preferably in the range of 5 to 40%. The double-sided corrugated cardboard 15 can be manufactured so that the step 11 of the stepped core 10 and the step 11a of the stepped core 10a have different step sizes, respectively. It can also be manufactured so that the inclination angles 04 and 05 with respect to the direction W d are different. 9 and 10 show a cardboard manufacturing apparatus in which a part of the cardboard manufacturing apparatus shown in FIGS. 2 to 6 is modified.
