Description

【０００１】
【発明の属する技術分野】
本発明は、例えば印刷紙やシート等の表紙とボール紙や段ボール紙等の台紙とを重合して貼着する合紙機に係り、とりわけ表紙が薄い場合に用いられる合紙機の改良に関する。
【０００２】
【従来の技術】
従来、この種の合紙機としては、例えば特公昭４９−３５０３９号、実公昭５６−３９６２７号、実開昭６１−１７６３００号、実開昭６２−９８６６４号、実開昭６３−１６１２４５号等に記載された所謂吸着ドラム式のものが知られている。
当該合紙機は、基本的には、所定寸法に裁断された表紙を一枚づつ所定のタイミングで供給する表紙供給装置と、これからの表紙の裏面に糊付する糊付装置と、これからの表紙を吸着して一方向に回転する吸着ドラム装置と、所定寸法に裁断された台紙を一枚づつ所定のタイミングで供給する台紙供給装置と、吸着ドラム装置に依り吸着されつつ回転されて来た表紙の裏面に台紙供給装置からの台紙を重合して貼着する貼合装置と、から構成されている。
而して、この様なものは、糊付装置に依り糊付された表紙を吸着ドラム装置に的確に吸着させる為に、糊付装置には、糊転写ローラから表紙を剥離する為の剥離爪や剥離糸が設けられている。
【０００３】
【発明が解決しようとする課題】
ところが、この様なものは、剥離爪や剥離糸が設けられているので、当該部分の糊が除去されて筋が付き、表紙が厚い場合には、問題がないものの、表紙が薄い場合には、この筋が透き通って見える為に、見栄えが悪くなって商品価値が低下するという難点があった。
本発明は、叙上の問題点に鑑み、これを解決する為に創案されたもので、その課題とする処は、表紙が薄くても、見栄えを良くして商品価値を高める事ができる合紙機を提供するにある。
【０００４】
【課題を解決するための手段】
本発明の合紙機は、基本的には、所定寸法に裁断された表紙を一枚づつ所定のタイミングで供給する表紙供給装置と、表紙供給装置からの表紙の前端を掴持して一方向に回転する掴持ドラム装置と、掴持ドラム装置に依り回転される表紙の裏面に糊付する糊付装置と、所定寸法に裁断された台紙を一枚づつ所定のタイミングで供給する台紙供給装置と、掴持ドラム装置に依り掴持されつつ回転されて来た表紙の裏面に台紙供給装置からの台紙を重合して貼着する貼合装置と、から構成した事に特徴が存する。
【０００５】
表紙は、表紙供給装置に依り所定のタイミングで掴持ドラム装置へ供給される。掴持ドラム装置へ供給された表紙は、その前端が掴持されて一方向に回転される。掴持ドラム装置に依り回転される表紙は、回転の途中でその裏面に糊付装置に依り糊付される。
他方、台紙は、台紙供給装置に依り表紙供給装置に呼応した所定のタイミングで貼合装置へ供給される。
そして、掴持ドラム装置に依り掴持されつつ回転されて来た表紙と台紙供給装置から供給された台紙とは、貼合装置に於て表紙の裏面に台紙の表面が重合すべく貼着される。
掴持ドラム装置に依り表紙の前端を掴持した後にこの表紙の裏面に糊付装置に依り糊付けする様にしたので、従来の如く、剥離爪や剥離糸を用いて糊付装置から表紙を剥離する必要がなくなり、剥離爪や剥離糸に依って筋が付くのを防止する事ができる。
【０００６】
掴持ドラム装置は、一方向に回転されるドラムと、ドラムの外周の一部に設けられて径方向に開閉可能で表紙供給装置からの表紙を受止めて掴持し得る掴持体と、掴持体を常時閉状態に付勢するスプリングと、表紙を台紙に重合させるまでは掴持体を閉状態にすると共にそれ以外では開状態にする為のカム機構と、掴持体に依り掴持される表紙の前端部分のみをドラムの外周より若干突出させる為の隆起部とを具有していても良い。この様にすれば、ドラムの回転を利用して掴持体を開閉できるので、専用の開閉駆動機を設ける必要がない。又、隆起部を設けたので、これ以外のドラムの外周に糊が転写される事がないと共に、その設ける範囲も小さいので、合理的である。
【０００７】

【００１１】
糊付装置４は、掴持ドラム装置３に依り回転される表紙Ａの裏面に糊付するもので、この例では、掴持ドラム装置３の他側下位（図１に於て左側下位）に設けられて居り、掴持ドラム装置３に掴持された表紙Ａに接触して糊を転写し得る糊転写ローラ２１と、これに遠近可能に設けられて糊量を調整する為の糊量調整ローラ２２と、糊転写ローラ２１と糊量調整ローラ２２との上部に貯溜する糊を供給する糊供給管（図示せず）等から成っている。
而して、糊付装置４は、掴持ドラム装置３のドラム１１に対して遠近可能に設けられていると共に、表紙供給装置２から掴持ドラム装置３への表紙Ａの供給の有無を検出するセンサ（光センサ）２３を備えて居り、表紙供給装置２から掴持ドラム装置３へ表紙Ａが供給されない時には、掴持ドラム装置３のドラム１１から糊転写ローラ２１が離間してこれに糊が転写されない様にしてある。
【００１２】
台紙供給装置５は、所定寸法に裁断された台紙Ｂを一枚づつ所定のタイミングで供給するもので、この例では、掴持ドラム装置３の他側上位（図１に於て左側上位）に設けられて表面を下にしたボール紙や段ボール紙等の厚さが比較的厚い台紙Ｂを送給するものにしてあり、表紙供給装置２と略同様、台紙Ｂを前方（掴持ドラム装置３側、図１に於て右方）に送るベルトコンベア２４と、これの上方に設けられて台紙Ｂを押える為の適数の押えローラ２５と、ベルトコンベア２４の前方に設けられてこれからの台紙Ｂを停止させる前当板２６と、ベルトコンベア２４と前当板２６との間に設けられて停止された台紙Ｂを無回転状態で上下から挾持した後に前当板２６の退避と同時に送出方向へ回転される送出ローラ２７と、これからの台紙Ｂを案内する上下一対の案内ローラ２８とから成っている。而して、台紙供給装置５の前段位置（図１に於て左側）には、図略しているが、表面を下にして多数積層された台紙Ｂを一枚づつ供給する給紙装置が設けられている。

【００１４】
次に、この様な構成に基づいて作用を述解する。
表紙Ａは、給紙装置に依り一枚づつ給紙されて表紙供給装置２のベルトコンベア７と押えローラ８に依り搬送されてその前端が前当板９に当たって停止される。停止された表紙Ａは、送出ローラ１０に依り無回転状態で上下から挾持された後、所定のタイミングで前当板８の退避と同時に送出ローラ１０が送出方向へ回転される事に依り掴持ドラム装置３へ供給される。
表紙供給装置２から供給された表紙Ａは、開状態で下位付近に位置する掴持ドラム装置３の掴持体１２の可動爪１７に依り受止められた後、ドラム１１の回転に伴って掴持体１２の可動爪１７と固定爪１６に依り掴持される。つまり、ドラム１１が図２及び図３の状態から時計方向に若干回動すると、掴持体１２の可動爪１７がカム機構１４を介してスプリング１３に依り閉状態にされるので、表紙Ａの前端が掴持体１２の可動爪１７と固定爪１６に依り掴持される。
【００１５】
掴持ドラム装置３の掴持体１２に依り前端が掴持された表紙Ａは、隆起部１５がある先端部分の裏面が糊付装置４の糊転写ローラ２１に接触して糊付されると共に、それ以降の部分が糊の粘着力に依り糊転写ローラ２１に引っ付く事に依り糊付される。糊付された表紙Ａは、その前端が掴持ドラム装置３の掴持体１２に依り掴持されているので、糊付装置４の糊転写ローラ２１から簡単に剥離されて行き、ドラム１１の時計方向の回転に依り表紙Ａの前端がドラム１１の上位に位置される。そして、ドラム１１が回転して行き、表紙がＡない箇所が糊付装置４に対向しても、その外周面は隆起部１５の箇所より外径が小さいので、糊付装置４の糊転写ローラ２１に接触して糊付けされる事がない。
【００１６】
他方、台紙Ｂは、給紙装置に依り一枚づつ給紙されて台紙供給装置５のベルトコンベア２４と押えローラ２５に依り搬送されてその前端が前当板２６に当たって停止される。停止された台紙Ｂは、送出ローラ２７に依り無回転状態で上下から挾持された後、表紙供給装置２に呼応した所定のタイミングで前当板２６の退避と同時に送出ローラ２７が送出方向へ回転される事に依り案内ローラ２８を経て貼合装置６へ供給される。
そして、掴持ドラム装置３に依り掴持されつつ回転されて来た表紙Ａと台紙供給装置５から供給された台紙Ｂとは、貼合装置６の貼合ローラ２９とドラム１１とに依り強圧されて表紙Ａの裏面に台紙Ｂの表面が重合すべく貼着される。
この時、掴持ドラム装置３の掴持体１２は、カム機構１４を介してスプリング１３に依り開状態にされて表紙Ａの前端の掴持を開放している。
【００１７】
貼合装置６に依り貼合された表紙Ａと台紙Ｂとの貼合物Ｃは、圧着搬出装置３０の案内ローラ３１を経て上下のベルトコンベア３２に依り圧着されて搬出される。
搬出された貼合物Ｃは、表紙Ａの表面が下で台紙Ｂの裏面が上になっている。この様な一連の動作に依り、表紙Ａと台紙Ｂとは貼合されて貼合物Ｃが連続的に製造される。
表紙Ａの前端を掴持ドラム装置３に依り掴持した後に糊付装置４に依り糊付けする様にしたので、従来の如く、剥離爪や剥離糸を用いて糊付装置４の糊転写ローラ２１から表紙Ａを剥離する必要がなくなり、剥離爪や剥離糸に依って筋が付くのを防止する事ができる。
【００１８】
尚、表紙供給装置２と台紙供給装置５は、先の例では、掴持ドラム装置３を境にして表紙供給装置２を下位にすると共に、台紙供給装置５を上位にしたが、これに限らず、例えばこれらを逆にしても良い。
掴持ドラム装置３は、先の例では、掴持体１２の可動爪１７が直線移動するものであったが、これに限らず、例えば搖動するものであっても良い。
掴持ドラム装置３は、先の例では、隆起部１５が表紙Ａの前端部分だけの大きさであったが、これに限らず、例えば表紙Ａの長さに等しい大きさであっても良い。
【００１９】
【発明の効果】
以上、既述した如く、本発明に依れば、次の様な優れた効果を奏する事ができる。
（１）表紙供給装置、掴持ドラム装置、糊付装置、台紙供給装置、貼合装置とで構成し、とりわけ表紙供給装置からの表紙の前端を掴持して一方向に回転する掴持ドラム装置と、掴持ドラム装置に依り回転される表紙の裏面に糊付する糊付装置とを設け、所謂掴持ドラム式にし、糊付装置で従来必要であった剥離爪や剥離糸を省略できる様にしたので、表紙が薄くても、見栄えを良くして商品価値を高める事ができる。

The bonded product C of the cover A and the mount B bonded by the bonding device 6 is pressure-bonded by the upper and lower belt conveyors 32 through the guide roller 31 of the pressure-carrying-out device 30, and is carried out.
The pasted product C carried out has the front surface of the cover A on the bottom and the back surface of the mount B on the top. According to such a series of operations, the cover A and the mount B are bonded together, and the bonded product C is continuously manufactured.
Since the front end of the cover sheet A is gripped by the gripping drum device 3 and then glued by the gluing device 4, the glue transfer roller 21 of the gluing device 4 is used using a peeling claw or a peeling thread as in the past. Therefore, it is not necessary to peel off the cover A, and it is possible to prevent streaking due to peeling nails and peeling threads.
[0018]
In the above example, the cover sheet supply device 2 and the mount sheet supply device 5 have the cover sheet supply device 2 at the lower position and the mount sheet supply device 5 at the upper position with the gripping drum device 3 as a boundary. For example, these may be reversed.
In the previous example, the gripping drum device 3 is such that the movable claw 17 of the gripping body 12 moves linearly. However, the gripping drum device 3 is not limited to this, and may be, for example, swinging.
In the previous example, the gripping drum device 3 has the protruding portion 15 that is only the size of the front end portion of the cover A. However, the gripping drum device 3 is not limited thereto, and may have a size equal to the length of the cover A, for example. .

【The invention's effect】
As described above, according to the present invention, the following excellent effects can be obtained.
(1) Gripping drum composed of a cover sheet supply device, a gripping drum device, a gluing device, a mount sheet supply device, and a bonding device, and in particular, grips the front end of the cover sheet from the cover sheet supply device and rotates in one direction. The device and a gluing device for gluing on the back surface of the cover that is rotated by the gripping drum device are provided so as to be a so-called gripping drum type, so that it is possible to omit the peeling claw and peeling thread that were conventionally required for the gluing device. Because of this, even if the cover is thin, it can improve the appearance and increase the product value.
