次に完全密封動作について説明する。前記通常動作では、包装するフイルムＦ，Ｆの横方向と縦方向の接着部間に僅かな隙間ができるので、これを完全に密封するため完全密封動作が行なわれる。
（１）〜（９）は通常動作と同じである。
（１０）接着ヒータ１００で一度融着した後に電磁ブレーキ７３をＯＦＦしメインモータ８０を起動させて新聞紙Ｐを僅かに搬送させ、停止した後再び電磁ブレーキ７３をＯＮし第２ソレノイド９１，９１を励磁してフイルムＦ，Ｆを長手方向に位置をずらして融着する。
（１１）下方へ搬送される包装された新聞紙Ｐは第４センサー７１でその後端を検知されると、次の新聞紙Ｐの受入状態に戻る。
着ヒータ１００で加圧・加熱して接着する。
（１２）フイルム包装を完成した新聞紙Ｐは架台３の排出ガイド８２に落下して滑り落ち、ホッパー８５に受け止められて堆積する。
【００２７】
前記各第１センサー５４ａ，５４ｂ、第２センサー５５ａ，５５ｂ、第４センサー７１，７１ａは、第１送りテーブル１３及び第２送りテーブル１４を搬送される新聞紙Ｐが途中で詰りトラブルを起した場合、それらを検知する機能を備えており、次にこれらを順に詳しく説明する。
【００２８】
通常、挿入口５から新聞紙Ｐが投入されると、該新聞紙Ｐは第１センサー５４ａ，５４ｂで検出され、サブモータ５０が起動し開閉ガイド部材１５を開き新聞紙Ｐを自重で落下させようとするが、この際、前記新聞紙Ｐが傾いて投入され詰り、その後第２センサー５５ａ，５５ｂが前記新聞紙Ｐを検知しないとき（表の（Ａ）の位置）操作パネル１２にエラーを表示すると共にブザーを鳴らす。この対処としては、前記新聞紙Ｐを再び真っすぐにして入れ直す。
【００２９】
前記自重で落下する新聞紙Ｐはその後端を第１センサー５４ａ，５４ｂまたは第２センサー５５ａ，５５ｂが検知した後、所定の時間経過後にメインモータ８０が停止して第１・第２ソレノイド９０，９０，９１，９１が励磁されるが、この際、前記新聞紙Ｐの後端が第１センサー５４ａ，５４ｂより上方または第１センサー５４ａ，５４ｂと第２センサー５５ａ，５５ｂとの間で停止して新聞紙Ｐが詰ったとき（表の（Ｂ）の位置）、第１センサー５４ａ，５４ｂ及び第２センサー５５ａ，５５ｂが共にＯＮ状態のままとなるか、第２センサー５５ａ，５５ｂのみがＯＮ状態となる。そこで、これらの場合も前記と同様に新聞紙Ｐが詰っていることを知らせるため操作パネル１２にエラーを表示すると共にブザーを鳴らす。この対処としては、包装機本体１内を開けメンテナンスを行う。
【００３０】
また、新聞紙Ｐが第２送りテーブル１４側に搬送され、フイルムＦ，Ｆを融着・切断した後は、下方へ搬送され、第４センサー７１が包装された新聞紙Ｐの後端を検知して、次の新聞紙投入の準備に入るが、そこで詰ったとき（表の（Ｃ）の位置）、第４センサー７１がＯＮ状態のままとなる。この場合も詰っていることを知らせるため操作パネル１２にエラーが表示される。そこで、この場合操作パネル１２の強制排出スイッチボタン１０７を押して排出を行う。しかし、なお搬送されないときは操作パネル１２に未だ詰っていることを表示することとなる。因に、この場合は、包装機本体１内を開けてメンテナンスを行う。
【００３１】
【発明の効果】
以上に述べたように本発明に係わる新聞紙のフイルム包装機は、４つ折りした新聞紙を挿入口から順次垂直に落下させ、その両側面を挟むようにフイルムを供給して新聞紙の上下左右でフイルムを加熱融着し、かつ上下で切断して包装するものであるから、包装機本体をコンパクトな縦型に形成することができ広い設置場所を必要としない。しかも、高速度にて連続的に運転して包装することができるので作業能率が向上すると共に、キャスターにより移動も自由である。
【００３２】
また、フイルムはロール巻きしたものを駆動軸と従動軸とで回転支持させるようにしたから大径ロール巻きのものを使用することができてフイルム補充の手間を減らすことができる。
【００３３】
さらに、包装機本体内で新聞紙が詰るなどのトラブルが起きても、各第１・第２・第４センサーで検知されるので、詰るなどのトラブルの箇所が簡単に解り対処もし易く、作業上有益である。

These are provided with a function for detecting them, and these will be described in detail below.
[0028]
Normally, when newspaper P is inserted from the insertion slot 5, the newspaper P is detected by the first sensors 54a and 54b, and the sub motor 50 is activated to open the open / close guide member 15 and attempt to drop the newspaper P by its own weight. At this time, when the newspaper P is thrown and clogged and the second sensors 55a and 55b do not detect the newspaper P (position (A) in the table), an error is displayed on the operation panel 12 and a buzzer is sounded. . As a countermeasure, the newspaper P is straightened again.
[0029]
The newspaper P that falls under its own weight has its rear end detected by the first sensor 54a, 54b or the second sensor 55a, 55b, and then the main motor 80 stops after a predetermined time has elapsed, and the first and second solenoids 90, 90 , 91, 91 are excited. At this time, the rear end of the newspaper P stops above the first sensors 54a, 54b or between the first sensors 54a, 54b and the second sensors 55a, 55b, and the newspaper is stopped. When P is clogged (position (B) in the table), both the first sensors 54a and 54b and the second sensors 55a and 55b remain in the ON state, or only the second sensors 55a and 55b are in the ON state. . In these cases, an error is displayed on the operation panel 12 and a buzzer is sounded to notify that the newspaper P is jammed in the same manner as described above. As a countermeasure, the inside of the packaging machine body 1 is opened and maintenance is performed.
[0030]
Further, after the newspaper P is conveyed to the second feed table 14 side and the films F and F are fused and cut, the newspaper P is conveyed downward, and the fourth sensor 71 detects the rear end of the wrapped newspaper P. The preparation for the next newspaper insertion starts, but when it is jammed there (position (C) in the table), the fourth sensor 71 remains in the ON state. In this case as well, an error is displayed on the operation panel 12 to notify that it is clogged. Therefore, in this case, the forced discharge switch button 107 on the operation panel 12 is pressed to perform discharge. However, when it is still not conveyed, it is displayed that the operation panel 12 is still clogged. In this case, the inside of the packaging machine body 1 is opened for maintenance.

【The invention's effect】
As described above, the newspaper film wrapping machine according to the present invention sequentially drops four folded newspapers vertically from the insertion slot, and supplies the film so as to sandwich the both sides thereof, and the film is placed on the upper, lower, left and right sides of the newspaper. Since it is heat-fused and cut and packaged at the top and bottom, the packaging machine main body can be formed into a compact vertical shape, and a wide installation place is not required. Moreover, since it can be continuously operated and packaged at a high speed, the work efficiency is improved, and movement is also possible by a caster.
[0032]
In addition, since the roll-wrapped film is rotationally supported by the drive shaft and the driven shaft, it is possible to use a large-diameter roll-wrap and reduce the trouble of film replenishment.
[0033]
Furthermore, even if a trouble such as a newspaper jam in the packaging machine occurs, it is detected by each of the first, second and fourth sensors, so the trouble location such as a jam can be easily solved and dealt with easily. It is beneficial.
