Description
本発明は、多数の段ボール箱等を製造する際の原材料となる段ボール素材に折罫を付与する装置に関する。
The present invention relates to an apparatus for applying a crease to a corrugated cardboard material which is a raw material when manufacturing a large number of corrugated cardboard boxes and the like.
本発明が解決しようとする課題は、連続した両面段ボール素材に、両面方向に均等に折ることができる折罫を付与する装置を提供することである。
The problem to be solved by the present invention is to provide an apparatus for applying a crease that can be folded evenly in both directions to a continuous double-sided cardboard material.
本発明に係る両面段ボール素材への折罫付与装置では、両面段ボール素材は、その幅方向（JIS-Z0104段ボール用語3006）においては全幅に亘る長さで、流れ方向（JIS-Z0104段ボール用語3005）においてはその厚さの0.5〜2倍の長さで第１押圧部と第２押圧部により押圧される。このようにして形成された折罫は、対象とする両面段ボール素材の両面において僅かの（その厚さの0.5〜2倍以内の）位置的差異はあるものの、そこで一方の側に折ったときと他方の側に折ったときの厚さには差がない。また、その間の折り罫も1本だけであるため、折り畳み厚さも小さい。従って、両面段ボール素材をジャバラ状に折り畳んだとき、均等かつ高密度に折り畳むことができる。なお、本発明に係る折罫付与装置が対象とする両面段ボール素材は、紙製のもののほか、プラスチック製のものであってもよい。
In the crease imparting device for a double-sided cardboard material according to the present invention, the double-sided cardboard material has a length over the entire width in the width direction (JIS-Z0104 cardboard term 3006) and the flow direction (JIS-Z0104 cardboard terminology 3005). Is pressed by the first pressing portion and the second pressing portion with a length 0.5 to 2 times the thickness. The crease formed in this way has a slight positional difference (within 0.5 to 2 times its thickness) on both sides of the target double-sided cardboard material, but when folded on one side there There is no difference in thickness when folded to the other side. Also, since there is only one crease between them, the folding thickness is small. Therefore, when the double-sided cardboard material is folded in a bellows shape, it can be folded evenly and with high density. Note that the double-sided cardboard material targeted by the crease imparting apparatus according to the present invention may be made of plastic in addition to paper.
また、第１押圧部及び第２押圧部は、それぞれ押罫ローラの表面に設けてもよい。この場合、前記駆動手段は各押罫ローラを回転させることにより第１押圧部と第２押圧部を駆動する。
Moreover, you may provide a 1st press part and a 2nd press part in the surface of a ruled roller , respectively. In this case, the driving means drives the first pressing portion and the second pressing portion by rotating each ruler roller .
さらには、第１押圧部を押罫ローラの表面に設けて回転させ、第２押圧部をそれに対向した位置に配置しておき、第１押圧部の回転押圧に従動して弾性的に退避するような構造としてもよい。なお、第１押圧部の回転押圧に従動して弾性的に退避するのではなく、第１押圧部の回転押圧に同期して移動するように制御されるものであってもよい。
Further, the first pressing portion is provided on the surface of the ruled roller and rotated, and the second pressing portion is disposed at a position facing the first pressing portion, and is elastically retracted following the rotational pressing of the first pressing portion. It is good also as such a structure. In addition, it may be controlled so as to move in synchronization with the rotational pressing of the first pressing part, instead of elastically retracting following the rotational pressing of the first pressing part.
両面段ボール素材の厚さが大きい場合、上記のように片面に1本の折罫のみを付与するだけでは、180°折り曲げたときに折りの外側に大きな引張力がかかり、段ボール素材の外面が割れることがある。そのような場合には、上記のような折罫を近接して2本形成してもよい。
すなわち、上記折罫付与装置は、更に、
c) 前記第１押圧部及び前記第２押圧部の押圧箇所から前記両面段ボール素材の厚さの2〜4倍の距離を置いて同様に押圧するように設けられた第３押圧部及び第４押圧部と、
d) 前記第３押圧部と第４押圧部を前記第１押圧部と第２押圧部と同様に駆動する第２駆動手段と
を備えることを特徴とする。
If the thickness of the double-sided cardboard material is large, applying only one crease on one side as described above will cause a large tensile force on the outside of the fold when folded 180 °, and the outer surface of the cardboard material will break. Sometimes. In such a case, two creases as described above may be formed close to each other.
That is, the crease providing device further includes:
c) Third and fourth pressing portions provided so as to be pressed in the same manner at a distance of 2 to 4 times the thickness of the double-sided cardboard material from the pressing locations of the first pressing portion and the second pressing portion. A pressing part;
d) Second driving means for driving the third pressing portion and the fourth pressing portion in the same manner as the first pressing portion and the second pressing portion.
両面段ボール素材にこのように近接して2本の折罫を形成することで、両面段ボール素材をジャバラ状に折り畳む際にはこれらの近接した折罫がそれぞれ折れ曲がる。これにより、1つの罫における折れ曲がり角度はほぼ90°となり、両面段ボール素材の外面の破れを防ぐことができる。
By forming two creases so close to the double-sided cardboard material, when the double-sided cardboard material is folded in a bellows shape, these adjacent creases are bent respectively. As a result, the bending angle of one ruled line is approximately 90 °, and the outer surface of the double-sided cardboard material can be prevented from being broken.
本発明に係る両面段ボール素材への折罫付与装置によれば、連続した両面段ボール素材に、両面方向に均等に折ることができる折罫を付与することができる。
According to the crease imparting device for a double-sided cardboard material according to the present invention, a crease that can be folded evenly in the double-side direction can be imparted to a continuous double-sided cardboard material.
図１により、両面段ボール素材の製造工程の一例を説明する。表ライナー紙６１のロール１２、中しん紙６２のロール１４、裏ライナー紙６３のロール１６からそれぞれ原紙６１、６２、６３が引き出され、まず、シングルフェイサ２０においてコルゲータ２１により中しん紙６２に波形の段が形成され、表ライナー紙６１と接着されて片面段ボール１７が製造される。次にダブルフェイサ３０において、この片面段ボール１７の波板側に裏ライナー紙６３が接着され、両面段ボール素材６０が製造される。なお、各原紙は接着剤による貼合前にヒータ２２、３１、３２により加熱され、製造された両面段ボール素材６０もヒータ３３により加熱され、接着が養生（固定）される。
An example of the manufacturing process of the double-sided cardboard material will be described with reference to FIG. The base papers 61, 62, and 63 are drawn out from the roll 12 of the front liner paper 61, the roll 14 of the medium liner paper 62, and the roll 16 of the back liner paper 63, respectively. First, the corrugator 21 in the single facer 20 forms the intermediate paper 62. Corrugated steps are formed and bonded to the front liner paper 61 to produce a single-sided cardboard 17. Next, in the double facer 30, the back liner paper 63 is adhered to the corrugated side of the single-sided cardboard 17, and the double-sided cardboard material 60 is manufactured. Each base paper is heated by the heaters 22, 31, and 32 before being bonded with the adhesive, and the manufactured double-sided cardboard material 60 is also heated by the heater 33 to cure (fix) the adhesion.
製造された両面段ボール素材６０は、本発明に係る折罫付与装置１００により所定の長さ毎に両面側から折罫が形成される。その後、スタッカー４２において交互に折り込まれ、ジャバラ状に折り畳まれる。その様子を図２に示す。図２(a)の紙面の左から折罫が付与された両面段ボール素材６０が供給される。両面段ボール素材６０に付与された折罫Aは、両面段ボール素材６０に押しだされることで図２(b)に示すように折れ曲がり、ジャバラ状に積み重ねられる。
The manufactured double-faced cardboard material 60 is formed with creases from both sides at every predetermined length by the crease applying apparatus 100 according to the present invention. Thereafter, the sheets are alternately folded in the stacker 42 and folded into a bellows shape. This is shown in FIG. A double-sided cardboard material 60 to which a crease is given is supplied from the left side of the paper surface of FIG. The crease A given to the double-sided cardboard material 60 is bent and stacked in a bellows shape as shown in FIG.
本発明に係る折罫付与装置の第１の実施形態について、図３から図６を参照しつつ説明する。本実施形態の折罫付与装置１００は折罫の付与対象である両面段ボール素材６０の表面側に配置された第１押圧部１１１と、両面段ボール素材６０の裏面側に配置された第２押圧部１１２と、第１押圧部１１１を駆動する第１駆動部１２１と、第２押圧部１１２を駆動する第２駆動部１２２と、第１及び第２駆動部１２１、１２２に接続されこれらの動作を制御する制御部１３０で構成される。
A first embodiment of a crease applying apparatus according to the present invention will be described with reference to FIGS. 3 to 6. The crease providing device 100 according to the present embodiment includes a first pressing portion 111 disposed on the front surface side of the double-faced cardboard material 60 that is a crease application target, and a second pressing portion disposed on the back surface side of the double-faced cardboard material 60. 112, a first driving unit 121 that drives the first pressing unit 111, a second driving unit 122 that drives the second pressing unit 112, and the first and second driving units 121 and 122 connected to perform these operations. It is comprised by the control part 130 to control.
図４に第１及び第２押圧部１１１、１１２の構造を示す。第１押圧部１１１及び第２押圧部１１２は、それぞれ第１傾斜面１１１ａ及び第２傾斜面１１２ａを有し、これらの傾斜面の幅は両面段ボール素材６０の厚さwと同一である。また、第１及び第２傾斜面１１１ａ、１１２ａは両面段ボール素材６０の表面及び裏面に対する角度θ=45°を有する。第１及び第２押圧部１１１、１１２の、両面段ボール素材６０の幅方向に沿う方向の長さは、図３(b)に示すように、両面段ボール素材６０よりも長いため、両面ダンボール素材６０の全幅に亘って折罫を付与することができる。また、第１押圧部１１１と第２押圧部１１２は、両面段ボール素材６０を押圧した際に傾斜面１１１ａ及び１１２ａが対向するように、両面段ボール素材６０の流れ方向にずらした位置に配置されている。
FIG. 4 shows the structure of the first and second pressing portions 111 and 112. The first pressing portion 111 and the second pressing portion 112 have a first inclined surface 111a and a second inclined surface 112a, respectively, and the width of these inclined surfaces is the same as the thickness w of the double-faced cardboard material 60. The first and second inclined surfaces 111 a and 112 a have an angle θ = 45 ° with respect to the front and back surfaces of the double-faced cardboard material 60. The length of the first and second pressing portions 111 and 112 in the direction along the width direction of the double-sided cardboard material 60 is longer than the double-sided cardboard material 60 as shown in FIG. the Orikei can and grant child over the full width. Further, the first pressing portion 111 and the second pressing portion 112 are arranged at positions shifted in the flow direction of the double-sided cardboard material 60 so that the inclined surfaces 111a and 112a face each other when the double-sided cardboard material 60 is pressed. Yes.
なお、両面段ボール素材６０が押圧される幅は第１及び第２傾斜面１１１ａ、１１２ａの幅により決まる。この幅が短すぎると折罫からずれた位置が折れ曲がることがある。この幅が長すぎると段ボール箱として組み立てた際に折罫が段ボール箱の面に折罫が位置した場合、強度が低下したり見た目が良くないため好ましくない。各傾斜面の幅は両面段ボール素材の厚さの0.5から2倍程度の範囲とすることで、折罫に沿って折りたたむことができ、且つ段ボール箱とした際に強度を維持し、見た目が悪くなることを防ぐことができる。
Note that the width with which the double-faced cardboard material 60 is pressed is determined by the widths of the first and second inclined surfaces 111a and 112a. If this width is too short, the position deviated from the crease may be bent. If this width is too long, when the crease is positioned on the surface of the cardboard box when it is assembled as a cardboard box, the strength is lowered or the appearance is not good. The width of each inclined surface is in the range of about 0.5 to 2 times the thickness of the double-sided corrugated cardboard material, so that it can be folded along the crease and maintains strength when used as a corrugated cardboard box. Can be prevented.
また、両面段ボール素材６０の高さのずれ幅ｄは、第１又は第２傾斜面１１１ａ、１１２ａと両面段ボール素材６０がなす角度θに影響される。θが大きい場合にはずれ幅ｄを大きくすることができる一方で、両面段ボール素材６０に対して直角に近い面で押圧するため、両面段ボール素材６０のライナー紙が破れてしまう可能性がある。また、θが小さい場合には上述の両面段ボール素材６０の高さのずれ幅ｄが小さくなるため、折り曲げ難くなる。角度θを30°から60°程度とすることで、適当なずれ幅ｄを形成しつつ、ライナー紙が破れないように押圧することができる。
Further, the height deviation width d of the double-sided cardboard material 60 is affected by the angle θ formed by the first or second inclined surfaces 111a, 112a and the double-sided cardboard material 60. While it is possible to increase the deviated width d when θ is large, for pressing at nearly a right angle surface with respect to both surfaces cardboard material 60, it is possible that the liner paper sided cardboard material 60 will be torn. When θ is small, the height deviation width d of the double-sided corrugated cardboard material 60 is small, which makes it difficult to bend. By setting the angle θ to about 30 ° to 60 °, it is possible to press the liner paper so as not to break while forming an appropriate shift width d.
第１押罫ローラ２４１及び第２押罫ローラ２４２は、それぞれ両面段ボール素材６０の幅方向に延設され、両面段ボール素材６０よりも広い幅を有する。また、これらの表面には軸方向に延設された第１押圧部２１１及び第２押圧部２１２がそれぞれ設けられている。第１押圧部２１１及び第２押圧部２１２の形状は、第１の実施形態と同一である。なお、第１押圧部２１１が第１押罫ローラ２４１の下端に位置し、第２押圧部２１２が第２押罫ローラ２４２の上端に位置するときに、第１及び第２押圧部２１１、２１２にそれぞれ設けられた傾斜面が対向するように、第１押罫ローラ２４１と第２押罫ローラ２４２は、回転中心を両面段ボール素材６０の流れ方向にずらして配置されている。
The first ruler roller 241 and the second ruler roller 242 are each extended in the width direction of the double-sided cardboard material 60 and have a wider width than the double-sided cardboard material 60. Moreover, the 1st press part 211 and the 2nd press part 212 extended in the axial direction were each provided in these surfaces. The shape of the 1st press part 211 and the 2nd press part 212 is the same as 1st Embodiment. When the first pressing portion 211 is positioned at the lower end of the first ruler roller 241 and the second pressing portion 212 is positioned at the upper end of the second ruler roller 242, the first and second pressing portions 211 and 212 are arranged. The first ruled roller 241 and the second ruled roller 242 are arranged so that the rotation center is shifted in the flow direction of the double-sided cardboard material 60 so that the inclined surfaces provided on the opposite sides face each other.
上記実施形態の変形例として、図７(b)に示すように、第１及び第２押罫ローラの一方を平板にすることもできる。この変形例では両面段ボール素材６０の裏面側に第２押圧部３１２を有する平板３４２を配設し、表面側に第１押圧部３１１を有する第１押罫ローラ３４１を設けている。平板３４２には両面段ボール素材６０の流れ方向にリニアガイド３４２ａ（本発明におけるガイド）が設けられており、第２押圧部３１２はリニアガイド３４２ａ上を移動可能な構成となっている。また、第２押圧部３１２はバネ３４２ｂにより両面段ボール素材６０の流れ方向とは逆の方向に付勢されており、外力が加わらない状態では図７(b)に示す位置に配置される。なお、第１押圧部３１１と第２押圧部３１２は、第１押圧部３１１が第１押罫ローラ３４１の下端に位置し、第２押圧部３１２が図７(b)に示す位置にあるときに、互いの傾斜面が対向するように、それぞれ配置されている。
As a modification of the above embodiment, as shown in FIG. 7B, one of the first and second ruled rollers can be a flat plate. In this modification, a flat plate 342 having a second pressing portion 312 is provided on the back side of the double-sided cardboard material 60, and a first ruled roller 341 having a first pressing portion 311 is provided on the front side. The flat plate 342 is provided with a linear guide 342a (guide in the present invention) in the flow direction of the double-sided cardboard material 60, and the second pressing portion 312 is configured to be movable on the linear guide 342a. Further, the second pressing portion 312 is urged by a spring 342b in a direction opposite to the flow direction of the double-sided cardboard material 60, and is disposed at a position shown in FIG. 7B when no external force is applied. The first pressing portion 311 and the second pressing portion 312 are such that the first pressing portion 311 is positioned at the lower end of the first ruler roller 341 and the second pressing portion 312 is at the position shown in FIG. 7B. Further, they are arranged so that the inclined surfaces face each other.
次に本変形例の動作について説明する。制御部３３０からの制御指示により第１駆動部３２１が第１押罫ローラ３４１を回転駆動することで、第１押圧部３１１が第１押罫ローラ３４１の外周面に沿って移動する。第１押圧部３１１が下端にくると、両面段ボール素材６０が第１押圧部３１１と第２押圧部３１２の傾斜面に挟まれて押圧され、折罫が付与される。さらに第１押罫ローラ３４１が回転して第１押圧部３１１が第２押圧部３１２に近づくと、第２押圧部３１２が第１押圧部３１１に押され、バネ３４２ｂの付勢力に抗して両面段ボール素材６０の流れ方向にリニアガイド３４２ａに沿って移動する。これにより、両面段ボール素材６０は第１押圧部３１１と第２押圧部３１２の傾斜面の間に挟まれた状態で移動する。さらに第１押罫ローラ３４１が回転して第１押圧部３１１が両面ダンボール素材６０から離間すると、第２押圧部３１２に対する第１押圧部３１１からの力がなくなるため、第２押圧部３１２はバネ３４２ｂの付勢力によって図７（ｂ）に示す位置に戻る。本変形例でも、第１の実施形態と同様に図６に示すような折罫が形成される。
Next, the operation of this modification will be described. The first driving unit 321 rotates the first ruled roller 341 in accordance with a control instruction from the control unit 330, so that the first pressing unit 311 moves along the outer peripheral surface of the first ruled roller 341. When the 1st press part 311 comes to a lower end, the double-sided cardboard raw material 60 will be pinched | interposed into the inclined surface of the 1st press part 311 and the 2nd press part 312, and a crease will be provided. When the first ruler roller 341 further rotates and the first pressing portion 311 approaches the second pressing portion 312, the second pressing portion 312 is pressed by the first pressing portion 311 and resists the biasing force of the spring 342b. It moves along the linear guide 342a in the flow direction of the double-sided cardboard material 60. As a result, the double-sided cardboard material 60 moves while being sandwiched between the inclined surfaces of the first pressing portion 311 and the second pressing portion 312. Further, when the first pressing roller 341 rotates and the first pressing portion 311 is separated from the double-sided cardboard material 60, the force from the first pressing portion 311 to the second pressing portion 312 disappears, so the second pressing portion 312 is a spring. It returns to the position shown in FIG. 7B by the urging force of 342b. Also in this modified example, a crease as shown in FIG. 6 is formed as in the first embodiment.
第１押圧部４１１の押圧箇所からと第３押圧部４１３までの間隔、すなわち折罫の間隔はジャバラ状に折り畳んだ際の両面段ボール素材６０の折りの厚さに影響する。この間隔が短いと、折り厚さを小さくすることができるが、折りの外側のライナー紙の近い位置2つの折罫の力がかかるため、ライナー紙が破れ易くなる。前記折罫の間隔が長いと折りの厚さが大きくなるため、ジャバラ状に積み上げたときに高く積み上がることになり、広い保管場所が必要となる。前記折罫の間隔を両面段ボール素材６０の厚さの2から4倍とすることで折の厚さを抑えつつ、ライナー紙にかかる力を分散させることができる。
The distance from the pressing location of the first pressing portion 411 to the third pressing portion 413, that is, the interval between the creases, affects the folding thickness of the double-sided cardboard material 60 when folded in a bellows shape. When this interval is short, the fold thickness can be reduced, but the liner paper is easily torn because the force of the two creases near the outside of the fold liner paper is applied. If the interval between the creases is long, the thickness of the folds increases, and therefore, when stacked in a bellows shape, the folds are stacked high, and a large storage space is required. By setting the interval between the creases to 2 to 4 times the thickness of the double-sided cardboard material 60, the force applied to the liner paper can be dispersed while suppressing the thickness of the folds.
上記実施形態の両面段ボール素材は、紙を原材料とするもので説明したが、プラスチックシートを用いたプラダンについても、両面段ボール素材を製造する工程を従来のプラダンを製造する工程で置き換えれば、そのまま適用することができる。
The double-sided corrugated cardboard material of the above embodiment has been described using paper as a raw material, but it can also be applied to a Pradan using a plastic sheet if the process for producing the double-sided cardboard material is replaced with a process for producing a conventional pladan. can do.
別の参考として図１１(a)から(c)に示すように両面段ボール素材の片側に平板を用いることもできる。図１１(a)に示す構成では、両面段ボール素材６０の裏面側に平板７４２を配設し、表面側に凸条７１１ｂを有する第１押罫ローラ７４１を設けている。第１押罫ローラ７４１が第１駆動部７２１により回転駆動されることで両面段ボール素材６０が凸条７１１ｂと平板７４２により押圧され、折罫が付与される。この場合、表用の罫と裏用の罫を別々に形成する必要があり、それぞれに図１１(a)のような設備を設ける必要があるが、罫ローラの寿命は長くなる。
図１１(b)の構成では、平板８４２に凹条８１２ｃが設けられている。両面段ボール素材６０は第１駆動部８２１により回転駆動される第１押罫ローラ８４１の凸条８１１ｂと凹条８１２ｃにより押圧され、折罫が付与される。
図１１(c)の構成では、平板９１２に凸条９１２ｂが設けられている。両面段ボール素材６０は第１駆動部９２１により回転駆動される第１押罫ローラ９４１の凸条９１１ｂと凸条９１２ｂにより押圧され、折罫が付与される。As another reference, a flat plate may be used on one side of the double-sided cardboard material as shown in FIGS. In the configuration shown in FIG. 11A, a flat plate 742 is disposed on the back side of the double-sided cardboard material 60, and a first ruled roller 741 having a ridge 711b is provided on the front side. The first ruled roller 741 is rotationally driven by the first drive unit 721, whereby the double-sided cardboard material 60 is pressed by the ridges 711b and the flat plate 742, and a crease is given. In this case, it is necessary to form the front ruler and the rear ruler separately, and it is necessary to provide the equipment as shown in FIG. 11A, but the life of the ruler roller becomes longer.
In the configuration of FIG. 11B, the flat plate 842 is provided with a recess 812 c. The double-faced cardboard material 60 is pressed by the convex strips 811b and the concave strips 812c of the first ruled roller 841 that is rotationally driven by the first driving unit 821, and a crease is given.
In the configuration of FIG. 11 (c), the ridge 912 b is provided on the flat plate 912. The double-faced corrugated cardboard material 60 is pressed by the ridges 911b and ridges 912b of the first ruler roller 941 that is rotationally driven by the first drive unit 921 to give creases .
