Description

本発明は、製袋、製函などの紙加工の分野で用いられる糊塗布技術に関し、特に凹凸のあるような被接着対象物に対する糊塗布に有効な糊塗布装置に関する。   The present invention relates to a glue application technique used in the field of paper processing such as bag making and box making, and more particularly, to a glue application apparatus effective for applying glue to an object to be bonded having unevenness.

紙は、袋、封筒、箱、帳票など様々な形態に加工され、日常生活の多岐にわたる分野で用いられている。このような紙加工品の多くは糊付けにより組み立てられており、低コスト、大量生産のため、紙加工のための機械も多様なものが用いられる。その中で糊塗布は紙加工にあっては基本となる技術であるが、特に量産のための紙加工機械ではローラー方式の糊塗布装置が多用されている。   Paper is processed into various forms such as bags, envelopes, boxes, and forms, and is used in various fields of daily life. Many of these paper processed products are assembled by gluing, and various machines for paper processing are used for low cost and mass production. Among them, glue application is a basic technique in paper processing, but roller-type glue application devices are frequently used especially in paper processing machines for mass production.

ローラー方式の糊塗布装置は、第1のローラーの表面に延ばした糊を、第２のローラーの糊版に移し取り、これをさらに紙などの対象物（被塗布媒体）に転写する、といった構造を持つ。   The roller-type glue applicator has a structure in which the glue extended to the surface of the first roller is transferred to the glue plate of the second roller and further transferred to an object (medium to be applied) such as paper. have.

このように、ローラー方式の糊塗布装置は、構造が簡単であり、しかも連続して供給される被塗布媒体に対して効率的に糊を塗布できることが特徴として挙げられる。さらに、糊版の形状により糊塗布のパターンを自在に設定できるので、多様な形状の品目に迅速に対応できるのが大きな特徴である。また、通常は、糊が対象物（被塗布媒体）に均一に塗布されるよう工夫されている。   As described above, the roller-type glue application device has a simple structure, and is characterized in that the glue can be efficiently applied to a continuously supplied medium to be applied. Furthermore, since the paste application pattern can be freely set according to the shape of the paste plate, it is a great feature that it can quickly cope with items of various shapes. Moreover, usually, it has been devised so that the glue is uniformly applied to an object (medium to be applied).

特許文献１は、ローラー方式の糊塗布装置における糊供給の安定化のための発明であり、糊供給の制御装置について述べている。
特許文献２は、ローラー方式の塗布を、糊以外かつ紙以外に適用したものであるが、一様な塗布を実現する技術を開示している。 Patent Document 1 is an invention for stabilizing glue supply in a roller-type glue application device, and describes a glue supply control device.
Patent Document 2 discloses a technique for realizing uniform application, although a roller-type application is applied to materials other than glue and paper.

特開平６−１７０２９５号公報JP-A-6-170295 特開平９−３８５５１号公報Japanese Patent Laid-Open No. 9-38551

ところが、ローラー方式の糊塗布装置は、糊版と被塗布媒体の接触圧により糊を移行させるので、被塗布媒体の表面に凹凸があったり、強度の低いものである場合は、十分な接触圧がかけられず、糊版と被塗布媒体の接触が不完全になり安定した塗布状態が得られない。   However, since the roller-type glue applicator moves the glue by the contact pressure between the glue plate and the medium to be coated, if the surface of the medium to be coated is uneven or has a low strength, the contact pressure is sufficient. The contact between the adhesive plate and the medium to be coated becomes incomplete and a stable coating state cannot be obtained.

そこで本発明は、上記のように凹凸のある被塗布媒体であっても安定した塗布状態が得られる糊塗布装置を提供することを課題とする。   Therefore, an object of the present invention is to provide a glue application device that can obtain a stable application state even with a medium to be coated having irregularities as described above.

本発明の糊塗布装置は、糊を溜める容器である糊パンから糊をかき上げる糊供給ローラーと、糊を塗布する領域の形状に凸状に形成された糊版を外周上に設けた糊版ローラーを持ち、前記糊供給ローラーの回転によりかき上げた糊を前記糊版上に移し、さらに糊版上の糊を媒体に転写する糊塗布装置において、前記糊供給ローラーと前記糊版ローラーとが相反する回転方向となるローラー駆動部を有し、前記ローラー駆動部は、前記糊供給ローラーの周速と糊版の表面の周速とに速度差を生ぜしめる周速調整機構を有し、前記速度差により、前記糊供給ローラー上の糊が前記糊版に移行する際に糊溜りを生じせしめることを特徴とする。

The glue application device of the present invention includes a glue supply roller that scrapes glue from a glue pan, which is a container for storing glue , and a glue plate provided on the outer periphery with a glue plate formed in a convex shape in the shape of the area to which the glue is applied. In a glue application apparatus that has a roller, transfers glue glued up by rotation of the glue supply roller onto the glue plate, and further transfers the glue on the glue plate to a medium, the glue supply roller and the glue plate roller include has a roller driving section to be opposite the direction of rotation, the roller driving unit may have a peripheral speed adjusting mechanism causing a difference in speed and the peripheral speed of the peripheral speed and glue plate surface of said glue feed roller, wherein Due to the speed difference, when the paste on the paste supply roller moves to the paste plate, a glue pool is generated .

また、前記糊版が前記糊版上の糊を前記媒体に転写する際に、前記糊版の移動速度および移動方向が、前記媒体の移動方向および移動速度と同一であることを特徴とする。 Further, when the paste plate transfers the paste on the paste plate to the medium, the moving speed and moving direction of the paste plate are the same as the moving direction and moving speed of the medium.

本発明の糊塗布装置によれば、糊版に糊を移行させる際に、前記糊供給ローラーの周速と糊版ローラーの周速に速度差を設けることで糊溜りが形成されることにより、糊版から被塗布媒体への糊の移行がより確実になるため、凹凸を持つ表面や強度の低い表面に塗布することができ、広範な被塗布媒体への糊塗布が可能となる。   According to the paste application apparatus of the present invention, when transferring the paste to the paste plate, a paste pool is formed by providing a speed difference between the peripheral speed of the paste supply roller and the peripheral speed of the paste plate roller. Since the transfer of the glue from the paste plate to the medium to be coated becomes more reliable, the paste can be applied to a surface having unevenness or a surface with low strength, and the paste can be applied to a wide range of medium to be coated.

＜従来のローラー方式の糊塗布装置の構成＞
図１は、従来のローラー方式の糊塗布装置の基本構成を表わす。
図１（ａ）に示すように、糊供給ローラー１１は連続して回転する円筒形状の回転体であり（図例では時計回りに回転）、外周の一部が糊パン１６内の糊１５に浸されている。糊供給ローラー１１の回転に伴ない、糊１５がかき上げられ、ドクター１５により余分な糊が落とされ、略一定な膜厚に均される。なお、糊パン１６とは糊１５を溜める容器である。 <Configuration of conventional roller-type glue application device>
FIG. 1 shows a basic configuration of a conventional roller-type glue application device.
As shown in FIG. 1A, the glue supply roller 11 is a cylindrical rotating body that rotates continuously (rotates clockwise in the illustrated example), and a part of the outer periphery is used as the glue 15 in the glue pan 16. Soaked. As the glue supply roller 11 rotates, the glue 15 is lifted up, and excess glue is removed by the doctor 15, and the film is leveled to a substantially constant thickness. The glue pan 16 is a container for storing the glue 15.

糊版ローラー１２は、円筒形状の回転体であり、周上に糊版１３を持つ。糊版１３は糊を塗布する形状に成型されており、糊版ローラー１２の回転（図例では反時計方向）とともに糊供給ローラー１１に接し、糊供給ローラー１１上の糊を移し取る。図１（ｂ）は、糊供給ローラー１１上の糊が糊版１３に移行する様子を表わす。
さらに、糊版１３は、糊版ローラー１２と同期して同方向に動く被塗布媒体（媒体１８）に接し、糊１７を媒体１８に移行させる。図１（ｃ）は、糊版１３の糊が媒体１８に移行する様子を表わす。 The paste roller 12 is a cylindrical rotating body and has a paste plate 13 on the periphery. The paste plate 13 is formed in a shape to apply the paste, and contacts the paste supply roller 11 with the rotation of the paste plate roller 12 (counterclockwise in the illustrated example) to transfer the paste on the paste supply roller 11. FIG. 1B shows how the glue on the glue supply roller 11 moves to the glue plate 13.
Furthermore, the paste plate 13 contacts the application medium (medium 18) that moves in the same direction in synchronization with the paste roller 12, and transfers the paste 17 to the medium 18. FIG. 1C shows a state in which the glue on the glue plate 13 moves to the medium 18.

このようにして媒体１８に塗布された糊１７の態様を図２に示す。
図２は、糊１７が、媒体１８上に、所定の形状で、均一な膜厚で転写されていることを表わす。
また、糊供給ローラー１１上の糊が糊版１３に安定的に移行するよう、通常は、糊供給ローラー１１の周速と糊版１３の表面速度は等しくなるよう設定され、また、糊版１３の糊が糊版１３に安定的に移行するよう、通常は、糊版１３の表面速度と媒体１８の移動速度は等しくなるよう設定されている。 An embodiment of the glue 17 applied to the medium 18 in this way is shown in FIG.
FIG. 2 shows that the glue 17 is transferred onto the medium 18 in a predetermined shape and with a uniform film thickness.
Also, the peripheral speed of the glue supply roller 11 and the surface speed of the glue plate 13 are normally set to be equal so that the glue on the glue supply roller 11 is stably transferred to the glue plate 13. Usually, the surface speed of the paste plate 13 and the moving speed of the medium 18 are set to be equal to each other so that the paste can be stably transferred to the paste plate 13.

図３は、本発明の糊塗布装置による糊塗布の態様を示す図であり、図３（ａ）は糊供給ローラー３１上の糊が糊版１３に移行する様子を表わし、図３（ｂ）は、媒体１８に塗布された糊の態様を表わす。
図３（ａ）に示すように、本発明の糊塗布装置による糊塗布では、糊供給ローラー３１上の糊が糊版１３に移行する際に、糊溜り３５が形成される。
さらに、糊版１３上の糊が媒体１８に転写されると、図３（ｂ）に示すように、媒体１８には、平坦に塗布された糊３７とともに、膨らみを持つ糊溜り３５が形成される。この糊溜り３５を形成するところが本発明の糊塗布装置の特色である。 FIG. 3 is a view showing an aspect of glue application by the glue application device of the present invention. FIG. 3 (a) shows how the glue on the glue supply roller 31 moves to the glue plate 13, and FIG. 3 (b). Represents the mode of the glue applied to the medium 18.
As shown in FIG. 3A, in the glue application by the glue application device of the present invention, the glue reservoir 35 is formed when the glue on the glue supply roller 31 moves to the glue plate 13.
Further, when the paste on the paste plate 13 is transferred to the medium 18, as shown in FIG. 3B, the medium 18 is formed with a paste 37 having a bulge together with the paste 37 applied flatly. The The place where the glue pool 35 is formed is a feature of the glue application device of the present invention.

図３（ａ）における糊溜り３５は、平坦な糊３７より高く盛り上っており、糊版１３上の糊が媒体１８に移行する際に、いち早く媒体１８に接触するため、これが導入となり、媒体１８への確実な塗布が実現できる。これにより、糊版１３と媒体１８との間の押圧を従来の方式より弱めることができるため、媒体１８の表面がエンボスなどで凹凸があっても、また、媒体１８の表面の強度が低いものであっても、ローラー方式での糊塗布が可能となる。
同様に、媒体１８に塗布された糊溜り３５は、平坦に塗布された糊３７より高く盛り上っているため、媒体１８と糊付けされる他の媒体の表面に凹凸や強度不足があっても、安定した接着が得られる。 The glue reservoir 35 in FIG. 3A is raised higher than the flat glue 37, and when the glue on the glue plate 13 is transferred to the medium 18, it quickly comes into contact with the medium 18. A reliable application to the medium 18 can be realized. As a result, the pressure between the paste plate 13 and the medium 18 can be weakened as compared with the conventional method. Therefore, even if the surface of the medium 18 is uneven due to embossing or the like, the strength of the surface of the medium 18 is low. Even so, it is possible to apply glue in a roller system.
Similarly, since the glue reservoir 35 applied to the medium 18 is raised higher than the paste 37 applied flatly, even if the surface of the other medium to be glued with the medium 18 has irregularities or insufficient strength. Stable adhesion can be obtained.

糊溜り３５は、図３（ａ）に示すように、糊供給ローラー３１上の糊が糊版１３に移行する時点で形成される。このとき、糊供給ローラー３１上の糊の移動速度と糊版１３の表面の移動速度の間には僅かな差が生じるように設定されており、両者のズレにより糊溜り３５が生じる。すなわち、糊供給ローラー３１上の糊の移動速度をＶ１、糊版１３の表面の移動速度をＶ２とすると、
Ｖ１＜Ｖ２ または Ｖ１＞Ｖ２
の関係にある。なお、図３（ａ）の例は、Ｖ１＜Ｖ２の場合であり、このとき、糊溜り３５は糊版１３の移動方向の前側に形成される。 As shown in FIG. 3A, the glue reservoir 35 is formed when the glue on the glue supply roller 31 moves to the glue plate 13. At this time, it is set so that there is a slight difference between the movement speed of the glue on the glue supply roller 31 and the movement speed of the surface of the paste plate 13, and the glue pool 35 is generated due to the deviation between the two. That is, when the movement speed of the glue on the glue supply roller 31 is V1, and the movement speed of the surface of the glue plate 13 is V2,
V1 <V2 or V1> V2
Are in a relationship. The example of FIG. 3A is a case where V1 <V2, and at this time, the glue reservoir 35 is formed on the front side in the moving direction of the paste plate 13.

＜本発明の糊塗布装置の構成＞
図４は、本発明の糊塗布装置の構成例を示す斜視図である。
糊塗布装置１は、糊供給ローラー３１、糊版ローラー３２を持ち、糊供給ローラー３１により糊パン１６からかき上げた糊を、糊版ローラー３２の糊版１３に移し、さらに媒体１８に転写することは図１の構成と同様である。
図４に示す本発明の糊塗布装置１では、糊供給ローラー３１、糊版ローラー３２は、それぞれギアを介して駆動されており、糊供給ローラー３１は、糊供給ローラーギア４６を介してギアＡ４５ａにより、また、糊版ローラー３２は、糊版ローラーギア４７を介してギアＢ４５ｂにより回転力を伝達されている。 <Configuration of glue applying device of the present invention>
FIG. 4 is a perspective view showing a configuration example of the glue application device of the present invention.
The glue application device 1 has a glue supply roller 31 and a glue plate roller 32, and transfers the glue that has been lifted from the glue pan 16 by the glue supply roller 31 to the glue plate 13 of the glue plate roller 32 and further transfers it to the medium 18. This is the same as the configuration of FIG.
In the glue application device 1 of the present invention shown in FIG. 4, the glue supply roller 31 and the glue plate roller 32 are each driven via gears, and the glue supply roller 31 is gear A 45 a via the glue supply roller gear 46. Thus, the rotational force of the paste roller 32 is transmitted by the gear B 45 b via the paste roller gear 47.

本発明の糊塗布装置１は、Ａギア４５ａとＢギア４５ｂの間に周速調整機構４１が設けられている。
周速調整機構４１には、調整用モーター４２が付帯しており、周速調整機構４１は、調整用モーター４２が静止の状態ではＡギア４５ａとＢギア４５ｂの回転速度は等しく、調整用モーター４２が回転した場合は、この回転に応じてＡギア４５ａとＢギア４５ｂの間に回転速度の差が生じるよう構成された機械的機構である。このような機構としては、自動車に用いられることで知られる差動ギアがある。 In the glue applying device 1 of the present invention, a peripheral speed adjusting mechanism 41 is provided between the A gear 45a and the B gear 45b.
An adjustment motor 42 is attached to the peripheral speed adjustment mechanism 41. The peripheral speed adjustment mechanism 41 has the same rotational speed of the A gear 45a and the B gear 45b when the adjustment motor 42 is stationary, and the adjustment motor 42 When 42 rotates, it is a mechanical mechanism comprised so that a difference in rotational speed may arise between A gear 45a and B gear 45b according to this rotation. As such a mechanism, there is a differential gear known to be used in an automobile.

＜差動ギア＞
ここで図５を用いて差動ギアの説明を加える。
差動ギア５は、３つの入出力軸と遊星ギアを組み合わせて構成される。
差動ギア５の入出力軸のうち、対となる２つの軸、Ａ軸５６ａおよびＢ軸５６ｂはそれぞれａギア５５ａ、ｂギア５５ｂを持ち、ｃギア５７ａ、ｄギア５７ｂと噛み合っている。なお、ｃギア５７ａ、ｄギア５７ｂは遊星ギアであり、フレーム５１に固定された軸を芯にして回転する。
フレーム５１と一体となったｅギア５２はｆギア５３と噛み合い、ｆギア５３はＭ軸５４に回転力を伝える。 <Differential gear>
Here, a description of the differential gear will be added with reference to FIG.
The differential gear 5 is configured by combining three input / output shafts and a planetary gear.
Of the input / output shafts of the differential gear 5, two pairs of shafts, the A shaft 56a and the B shaft 56b, have an a gear 55a and a b gear 55b, respectively, and mesh with the c gear 57a and the d gear 57b. The c gear 57a and the d gear 57b are planetary gears, and rotate around an axis fixed to the frame 51.
The e gear 52 integrated with the frame 51 meshes with the f gear 53, and the f gear 53 transmits a rotational force to the M shaft 54.

自動車の場合は、Ｍ軸５４がエンジンユニットに繋がり回転力を得る。まずＭ軸５４からｅギア５２に伝達された回転力は、フレーム５１を経て、遊星ギアであるｃギア５７ａ、ｄギア５７ｂを介して伝達され、ａギア５５ａ、ｂギア５５ｂが回転することによりＡ軸５６ａ、Ｂ軸５６ｂ（すなわちタイヤ）を駆動する。このとき、ｃギア５７ａ、ｄギア５７ｂが不回転（自転しない）の状態であれば、Ａ軸５６ａ、Ｂ軸５６ｂは同方向に等速で回転する。Ａ軸５６ａ、Ｂ軸５６ｂに回転差が生じると、遊星ギア（ｃギア５７ａ、ｄギア５７ｂ）が回転差に応じて回転（自転）する。
なお、図示のａギア５５ａ、ｂギア５５ｂ、ｃギア５７ａ、ｄギア５７ｂ、ｅギア５２、ｆギア５３はベベルギアであり、噛み合うギアの軸は互いに直交関係をなす。 In the case of an automobile, the M shaft 54 is connected to the engine unit to obtain a rotational force. First, the rotational force transmitted from the M shaft 54 to the e gear 52 is transmitted through the frame 51 via the planetary gears c gear 57a and d gear 57b, and the a gear 55a and b gear 55b rotate. The A axis 56a and the B axis 56b (that is, tires) are driven. At this time, if the c gear 57a and the d gear 57b are in a non-rotating state (not rotating), the A shaft 56a and the B shaft 56b rotate at the same speed in the same direction. When a rotation difference occurs between the A shaft 56a and the B shaft 56b, the planetary gears (c gear 57a and d gear 57b) rotate (spin) according to the rotation difference.
Note that the illustrated a gear 55a, b gear 55b, c gear 57a, d gear 57b, e gear 52, and f gear 53 are bevel gears, and the shafts of the meshing gears are orthogonal to each other.

＜本発明の糊塗布装置の作用＞
図４の糊塗布装置について説明を続ける。
糊塗布装置１の周速調整機構４１に、図５に示す作動ギアを適用した場合、図５におけるＡ軸５６ａ、Ｂ軸５６ｂが糊塗布装置１のＡギア４５ａ、Ｂギア４５ｂの軸に対応し、Ｍ軸５４に相当する軸に調整用モーター４２が繋がる。 <Operation of the glue application device of the present invention>
The description of the glue application device of FIG. 4 will be continued.
When the operating gear shown in FIG. 5 is applied to the peripheral speed adjusting mechanism 41 of the glue applying device 1, the A shaft 56a and the B shaft 56b in FIG. 5 correspond to the axes of the A gear 45a and the B gear 45b of the glue applying device 1. Then, the adjustment motor 42 is connected to an axis corresponding to the M axis 54.

例えば、原動（図示せず）からの駆動によりＢギア４５ｂが回転し、調整用モーター４２が不回転の場合、周速調整機構４１内の遊星ギアが自転し、ギアＡ４５ａの軸はＢギア４５ｂの軸と逆方向に等速で回転する。このとき、糊供給ローラーギア４６と糊版ローラーギア４７は互いに相反する方向に回転するので、糊供給ローラー１１上の糊の移動方向と糊版１３の表面の移動方向は同一となり、糊の移行は円滑に行われる。   For example, when the B gear 45b is rotated by driving from a driving force (not shown) and the adjusting motor 42 is not rotated, the planetary gear in the peripheral speed adjusting mechanism 41 rotates, and the shaft of the gear A45a is the B gear 45b. It rotates at the same speed in the opposite direction to the axis. At this time, since the glue supply roller gear 46 and the glue plate roller gear 47 rotate in directions opposite to each other, the movement direction of the glue on the glue supply roller 11 and the movement direction of the surface of the glue plate 13 are the same, and the transition of the glue is performed. Is done smoothly.

一方、Ｂギア４５ｂが回転し、調整用モーター４２も回転する場合、周速調整機構４１内では、図５のフレーム５１に相当する部分が回転し、Ａギア４５ａの軸とＢギア４５ｂの軸との間には調整用モーター４２の回転速度に応じた回転速度の差が生じるため、糊供給ローラー１１上の糊の移動速度と糊版１３の表面の移動速度との差から糊溜り３５が得られる。
調整用モーター４２が一定速度で回転していれば、前記移動速度の差は一定であり、安定した糊溜り３５が得られる。 On the other hand, when the B gear 45b rotates and the adjustment motor 42 also rotates, the portion corresponding to the frame 51 in FIG. 5 rotates in the peripheral speed adjustment mechanism 41, and the shaft of the A gear 45a and the shaft of the B gear 45b Since a difference in rotational speed according to the rotational speed of the adjustment motor 42 occurs between the two and the glue reservoir 35 from the difference between the movement speed of the glue on the glue supply roller 11 and the movement speed of the surface of the glue plate 13. can get.
If the adjustment motor 42 is rotating at a constant speed, the difference in the moving speed is constant, and a stable glue pool 35 is obtained.

なお、前記移動速度の差は微小であるので、調整用モーター４２は減速機構を内蔵したギアドモーターが好適である。
また、糊版１３が媒体１８と所定の位置で接するよう、搬送部４８と糊版ローラー３２は同期する必要があるため、糊版ローラー３２の回転力は搬送部４８の動力と同一の原動から得ることが望ましい。 Since the difference in the moving speed is very small, the adjustment motor 42 is preferably a geared motor with a built-in speed reduction mechanism.
Further, since it is necessary to synchronize the conveyance unit 48 and the paste plate roller 32 so that the paste plate 13 contacts the medium 18 at a predetermined position, the rotational force of the paste plate roller 32 is generated from the same driving force as the power of the conveyance unit 48. It is desirable to obtain.
