うものである。Conventional Techniques Technological means for opening and removing the wrapping paper of the web wrapping paper, which is performed mechanically without relying on manual labor, is disclosed, for example, in Japanese Patent Application Laid-Open No. 63-1999.
218034, JP 63-307030, JP 63-317431, etc.; The technical content of both methods is to roll up the folded edges of the outer wrapping paper that has been folded inward from the periphery of both ends of the web, and then cut and open the outer wrapping paper along the axis of the web. The technical content disclosed in Publication No. 63-307030 is as follows:
Without rolling up the folded edge of the wrapping paper, the wrapping paper covering the outer periphery of the web is cut with a laser beam, and the tongue piece of the wrapping paper peeling means is inserted into the cut opening to forcibly rotate the web. By moving the wrapping paper, the folded edge of the wrapping paper is also forcibly broken, and the wrapping paper is peeled off and removed.

かりでなく、外装紙が燃えるという危険もあった。Problems to be Solved by the Invention The former prior art described above is a complex system that includes a gripper mechanism for rolling up the folded side edge of the wrapping paper and a cutting/unsealing cutter inserted into the back side of the folded side edge. Not only does it require an opening head with a special mechanism, but it also avoids the overlapping parts of the starting and trailing ends where the wrapping paper is wrapped twice, and selects the single-layered part that can be easily opened and cut. Requires detection means etc. for cutting,
The opening and cutting operation is extremely troublesome and complicated, and since the latter conventional technology uses a laser beam to cut the outer wrapping paper, the thermal influence of the laser beam extends to the surface of the web, and even several sheets of the surface of the web are exposed. Not only was there a risk of the paper being cut, but there was also a risk that the outer wrapping paper would catch fire.
課題を解決するための手段
そこで、本発明は上述した従来技術の課題を解決するた
め、巻取紙を被包している外装紙の外周部分に巻取紙軸

紙をスリット部分より切断し開封させるものである。Means for Solving the Problems Therefore, in order to solve the above-mentioned problems of the prior art, the present invention creates slits such as tears, scars, or perforations in the axial direction of the web in the outer peripheral portion of the outer wrapping paper that encloses the web. grant,
By blocking the outer paper on one side of the slit line from rotating with a pressure pad and forcibly rotating the other side with a drive roller, a tensile force is applied to the slit line and the outer paper is slit. The package is cut into parts and opened.
作 用
外装紙の表面にスリット付与カッタで裂傷痕又はミシン
目を付けることにより分断し易くしたので、裂傷痕又は
ミシン目等のスリットを挾んで一側を押えパッドで押圧
固定し、他側を該スリットに分断方向の張力をかけると
、容易にスリットに沿って外装紙が分断される。Function: By creating lacerations or perforations on the surface of the outer wrapping paper with a slit-forming cutter, it was made easy to separate.The slits at the lacerations or perforations were held in between, and one side was pressed and fixed with a presser pad, and the other side was fixed. When tension is applied to the slit in the cutting direction, the wrapping paper is easily cut along the slit.
そして、分断後に前記押えパッドを外装紙表面より離隔
すると、外装紙はスリットより分断して開封されて下方
に展開するから、巻取紙を回動させて展開した外装紙の
分断端縁を引出し搬送することにより、外装紙を巻取紙
より除去するものである。Then, when the presser pad is separated from the surface of the outer wrapping paper after dividing, the outer wrapping paper is divided through the slit, unsealed, and unfolded downward, so the rolled paper is rotated and the divided edges of the unfolded outer wrapping paper are pulled out and conveyed. By doing so, the wrapping paper is removed from the web.

下端は外装紙面当接ローラ４ｃの下端に対して切り込み
深さに相当する分だけ僅かに下方に突出している。The opening head 4 suspended from the lower ends of the lifting drive rods 8a and 8b is provided with a slitter rotary blade 4a and a drive motor 4b for the blade 4a, and an exterior paper surface contact roller 4C is provided at a position opposite to the blade 4a. The lower end of the slitter rotary blade 4a slightly protrudes downward by an amount corresponding to the cutting depth with respect to the lower end of the outer paper surface abutting roller 4c.
そして、開封ヘッド４の側部には、外装紙面当接ローラ
４ｃが外装紙表面に当接したことを検知する検知ローラ
９が垂設され、該検知ローラからの検知信号により開封
ヘッド４の降下動作は停止する。A detection roller 9 is installed vertically on the side of the unsealing head 4 to detect when the outer packaging paper surface contact roller 4c has come into contact with the outer packaging paper surface, and the unsealing head 4 is lowered by a detection signal from the detection roller. The operation stops.
そこで、外装紙に包装された巻取紙１が支承ローラ３ａ

向の裂傷痕が刻設される。Then, when the screw shaft 10 screwed onto the cart 8 is driven to rotate in the normal direction by the motor M, the cart 8 moves forward on the guide rail 5 and the unsealing head 4 moves along the paper roll axis. 4b to rotate the slitter rotary blade 4a, the rotary blade 4a inscribes tear marks in the wrapping paper in the axial direction of the web.
なお、スリッタ回転刃４ａがミシン目刻設刃であるとき
は、駆動モータ４ｂを不要とし、開封ヘッド４の走行に
伴って回転刃が回動し、外装紙上にミシン目を刻設する
ことができる。Note that when the slitter rotary blade 4a is a perforation-carving blade, the drive motor 4b is not required, and the rotary blade rotates as the opening head 4 travels to carve perforations on the outer wrapping paper. can.

部も破断せしぬられる。Next, the paper presser cylinder 7C is extended to press the outer paper presser pad 7a to one side of the tear mark, and then the support rollers 3a and 3b are driven in normal rotation to cut the slit at the tear mark or perforation. When the roll paper 1 is rotated in the direction in which tension is applied, that is, in the clockwise direction (direction of arrow A) in FIG. Since the other side is blocked and cannot be rotated, the outer wrapping paper is divided along the slit edge, and the outer wrapping paper is cut and opened. At this time, the folded edges on both sides of the wrapping paper are also sewn without being broken.

By driving, the slit end of the wrapping paper on the presser pad side unfolds and falls onto the paper discharge belt conveyor 11, and is sent to a shredder or the like by the conveyor 11 and shredded.
なお、該コンベヤ１１には裁断カッタ等を付設して外装
紙の長さを適量分断してシュレ・ソダに送ってもよい。Note that the conveyor 11 may be provided with a cutting cutter or the like to cut the wrapping paper into appropriate lengths and send it to the shret/soda.

化に画期的な役割を果すことができるものである。Effects of the Invention In the present invention, the cutting edge of the pickpocket/vine rotating blade attached to the opening head slightly protrudes from the circumferential surface of the outer paper surface contact roller, so that the cutting edge of the pickpocket/vine rotating blade does not touch the wrapping paper. There is no risk of scratching the surface of the wrapped paper because it does not reach the surface of the wrapped paper, and the degree of pickpocketing and soto engraving on the surface of the wrapping paper by the cutting edge of the pickpocket rotary blade is limited depending on the undulations of the surface of the wrapping paper. Even if there is a part where slits are not engraved due to insufficient cutting, the slit engraved line of the outer wrapping paper is held between the slit engraved lines and one tearing tension is applied to both sides, so the outer wrapping paper is reliably divided along the slit line. Furthermore, even if the outer packaging paper is opened and unfolded due to being cut and dropped,
It can be easily ejected by forward and reverse rotation of the web support roller and removed from the web, and the wrapping paper surrounding the web can be mechanically opened and removed without relying on manual means. In particular, it can play a revolutionary role in automating the newspaper printing process.
