【従来の技術】[Prior Art]

図3は、従来の冷間圧延における通板装置を示す。同図において1は鋼帯であ り、この鋼帯1は圧延ロール群10a,10bに上下方向から押されて圧延され る。 2は鋼帯のコイルであり、このコイル2はコイル状に巻くことにより生ずる巻 きずれを防止するために鋼帯間に紙5を挾んで巻いている。3はコイル2の巻き リールであり、4は方向変換用のロール、6は紙用のリールである。 また、7a,7b,7c,7dは鋼帯1および紙5の進行方向を示している。 FIG. 3 shows a conventional strip passing apparatus in cold rolling. In the figure, 1 is a steel strip, and this steel strip 1 is pressed by the rolling roll groups 10a and 10b from the vertical direction and rolled. Reference numeral 2 is a coil of a steel strip, and the coil 2 has a paper 5 sandwiched between the steel strips in order to prevent a winding deviation caused by winding in a coil shape. 3 is a winding reel of the coil 2, 4 is a roll for changing direction, and 6 is a reel for paper. Moreover, 7a, 7b, 7c, and 7d have shown the advancing direction of the steel strip 1 and the paper 5.

【0003】 この図3で示す進行方向は、コイル2を巻きほどき鋼帯1を左方向に送り出し 、圧延ロール群10a,10bを通過させ、リール13で鋼帯1を再度紙15と 共に巻き、コイル12を形成することを示している。 コイル2から送り出された鋼帯1は、圧延油ノズル9a,9bから供給される 圧延油11を浴びて圧延ロール群10a,10bを通過しつつ圧延される。ここ で、圧延油11は圧延に伴う熱を除去すると共に鋼帯1の酸化を防止するための ものである。 18a,18bは圧延油ワイパであり、コイル状に鋼帯を巻く際に障害となる 過剰な圧延油を除去する。 14は鋼帯の方向変換ロールである。In the traveling direction shown in FIG. 3, the coil 2 is unwound, the steel strip 1 is sent out to the left, passed through the rolling roll groups 10a and 10b, and the steel strip 1 is rewound with the paper 15 by the reel 13. , Forming the coil 12. The steel strip 1 sent out from the coil 2 is bathed with the rolling oil 11 supplied from the rolling oil nozzles 9a and 9b, and is rolled while passing through the rolling roll groups 10a and 10b. Here, the rolling oil 11 is for removing heat associated with rolling and for preventing oxidation of the steel strip 1. Reference numerals 18a and 18b denote rolling oil wipers, which remove excess rolling oil which is an obstacle when winding the steel strip in a coil shape. Reference numeral 14 is a steel strip direction changing roll.

【0004】 矢印17a,17b,17c,17dは鋼帯1および紙15の進行方向を示し ている。鋼帯1はリール13によりコイル12に巻かれるが、前述のごとく巻き ずれ防止のため紙15も鋼帯1と共に巻かれることになる。 16は紙15を供給する紙リールである。Arrows 17 a, 17 b, 17 c, 17 d indicate the traveling directions of the steel strip 1 and the paper 15. The steel strip 1 is wound around the coil 12 by the reel 13, but as described above, the paper 15 is also wound together with the steel strip 1 to prevent the winding deviation. Reference numeral 16 is a paper reel that supplies the paper 15.

【0005】 圧延動作は鋼帯1を図の左方向と右方向とに交互に走らせて行なわれる。この 図3の説明では矢印7b,17bのように図の左方向に走らせる場合を述べたが 、コイル2がコイル12に巻きとられた後には逆転させて鋼帯1を矢印7b,1 7bと逆方向に進行させる。 この際には圧延油ワイパ18a,18bおよび圧延油ノズル9a,9bは休止 させて、圧延油ワイパ8a,8bおよび圧延油ノズル19a,19bを作動させ る。The rolling operation is performed by running the steel strip 1 alternately in the left direction and the right direction in the figure. In the description of FIG. 3, the case where the steel strip 1 is run to the left as shown by arrows 7b and 17b has been described. And proceed in the opposite direction.

【考案が解決しようとする課題】[Problems to be solved by the device]

上述の図3に示す装置にあっては、鋼帯1を紙5と分離するに当り不具合が発 生する。すなわち、紙5には鋼帯1に付着した圧延油がしみ込んでいるので、紙 リール6に巻き取る際に破断しやすく、破断が起きて、作業員がこれを見すごす と、紙5は鋼帯1に付着したまま、圧延ロール群10a部に侵入し、圧延作業の 中断を引き起こすという問題がある。この場合、圧延油ワイパ8a,8bを閉じ て紙5の侵入を防止しようとしても、今度は圧延油ワイパ8a,8bの故障を引 き起こし、いずれにせよ圧延作業の支障となるという問題がある。 In the apparatus shown in FIG. 3 described above, a problem occurs when the steel strip 1 is separated from the paper 5. That is, since the rolling oil adhering to the steel strip 1 has soaked into the paper 5, the paper 5 easily breaks when it is wound on the paper reel 6, and when a break occurs and a worker looks at it, the paper 5 becomes steel. There is a problem in that it sticks to the strip 1 and enters the rolling roll group 10a to interrupt the rolling operation. In this case, even if the rolling oil wipers 8a and 8b are closed to prevent the invasion of the paper 5, this time, the rolling oil wipers 8a and 8b will be out of order, which will hinder the rolling operation in any case. ..

【0007】 本考案は、鋼帯への紙の付着を防止した通板装置の提供を目的とする。An object of the present invention is to provide a threading device which prevents paper from adhering to a steel strip.

【0008】[0008]

【課題を解決するための手段】[Means for Solving the Problems]

上述の目的を達成する本考案は、紙を挾んで巻かれた鋼帯を巻きほどき紙と鋼 帯とを分離する通板装置において、上記紙と鋼帯との分離後のこの鋼帯の通板ラ イン近傍に紙センサを備え、この紙センサによる紙検出にて鋼帯上にエアジェッ トを吹き付けるエアノズルを備えたことを特徴とする。 The present invention that achieves the above-mentioned object is to provide a stripping device for unwinding a steel strip wound by sandwiching a paper and separating the paper and the steel strip from each other. A paper sensor is provided in the vicinity of the threading line, and an air nozzle that blows an air jet onto the steel strip by the paper detection by the paper sensor is provided.

【0009】[0009]

【作用】[Action]

鋼帯に紙が付着しても光学センサからの信号にてエアノズルからエアジェット が吹き付けられ、このため鋼帯から紙が引きはがされる。この結果、紙の破断が 発生しても圧延作業は続行できる。 Even if the paper adheres to the steel strip, an air jet is blown from the air nozzle by the signal from the optical sensor, which causes the paper to be stripped from the steel strip. As a result, the rolling operation can be continued even if the paper breaks.

【0010】[0010]

【実施例】【Example】

ここで、図1、図2を参照して本考案の実施例を説明する。図1、図2は図3 の右側に示す鋼帯1の送り出し側の構造を示し、同一部分には同一符号を付す。 図1において、1は鋼帯、2は鋼帯1と紙5が相互にまかれたコイル、3はリ ールである。方向変換用ロール4の上方には、鋼帯1を監視するようにセンサ2 0が配置されている。このセンサ20は、発光素子と反射光センサとにより構成 され、鋼帯1へ光が照射され鋼帯1の表面での反射光の変化により紙5の付着を 検出するものである。 An embodiment of the present invention will now be described with reference to FIGS. 1 and 2 show the structure on the delivery side of the steel strip 1 shown on the right side of FIG. 3, and the same parts are designated by the same reference numerals. In FIG. 1, 1 is a steel strip, 2 is a coil in which the steel strip 1 and the paper 5 are mutually wound, and 3 is a reel. A sensor 20 is arranged above the direction changing roll 4 so as to monitor the steel strip 1. The sensor 20 is composed of a light emitting element and a reflected light sensor, and detects the adhesion of the paper 5 by the change of the reflected light on the surface of the steel strip 1 when the steel strip 1 is irradiated with light.

【0011】 一方、方向変換用ロール4の接線方向に向ってエアジェットを吹き出す向きに エアノズル22が配置されている。このエアノズル22は、圧縮空気ラインにつ ながっており、この圧縮空気ラインの電磁バルブ21にて開閉制御される。電磁 バルブ21は、センサ20に接続され、センサ20により紙5の付着が検出され ると電磁バルブ21があけられ、エアジェット23が吹き出す。 したがって、鋼帯1への紙5の付着によりその付着面へエアジェット23が作 用して、紙5が鋼帯1から吹きはがされ除去される。On the other hand, the air nozzle 22 is arranged so as to blow out an air jet toward the tangential direction of the direction changing roll 4. The air nozzle 22 is connected to a compressed air line, and the electromagnetic valve 21 of the compressed air line controls opening / closing. The electromagnetic valve 21 is connected to the sensor 20, and when the attachment of the paper 5 is detected by the sensor 20, the electromagnetic valve 21 is opened and the air jet 23 blows out. Therefore, when the paper 5 adheres to the steel strip 1, the air jet 23 operates on the adhered surface, and the paper 5 is blown off from the steel strip 1 and removed.

【0012】 今、鋼帯1をコイル2より巻きほどいて圧延ロール群10a,10bに供給し 、圧延するものとする。このとき、鋼帯1及び紙5は矢印7a,7b,7c,7 dの方向に進行する。したがって、コイル2は巻きほどかれ、紙5はリール6に 巻かれて鋼帯1から分離される。そして、方向変換用ロール4では鋼帯1は圧延 ロール群10a,10bへの角度を保っている。 ここで、紙5が破れ、鋼帯1へ紙の付着が生じた場合、センサ20にてこの付 着が検出され、電磁バルブ21があけられて圧縮空気ラインにつながるエアノズ ル22よりエアジェットが吹き出す。この結果、鋼帯1より紙5が吹きはがされ る。Now, it is assumed that the steel strip 1 is unwound from the coil 2 and supplied to the rolling roll groups 10a and 10b for rolling. At this time, the steel strip 1 and the paper 5 advance in the directions of the arrows 7a, 7b, 7c, 7d. Therefore, the coil 2 is unwound and the paper 5 is wound around the reel 6 and separated from the steel strip 1. Then, in the direction changing roll 4, the steel strip 1 maintains the angle to the rolling roll groups 10a and 10b. Here, when the paper 5 breaks and the paper adheres to the steel strip 1, the sensor 20 detects the adhesion, and the electromagnetic valve 21 is opened to generate an air jet from the air nozzle 22 connected to the compressed air line. Blow out. As a result, the paper 5 is blown off from the steel strip 1.

【0013】 実施例ではセンサ20として検知光照射・反射光検知式の光学式センサを用い たが、単に鋼帯からの反射光を検知する方式のものや、電磁式センサ等非接触方 式のものの他、接触方式のセンサも代替として採用することができる。In the embodiment, an optical sensor of detection light irradiation / reflected light detection type is used as the sensor 20, but a sensor that simply detects the reflected light from the steel strip or a non-contact type sensor such as an electromagnetic sensor. In addition to the above, a contact type sensor can be adopted as an alternative.

【0014】 また、センサ20により紙5を検知したときに電磁バルブ21を開とする方式 を示したが、常時も少量の空気をノズル22から吹きだし紙5と鋼帯1の分離を 助勢しており、紙5を検知した時には、電磁バルブ21の開度を増して、破断し た紙5を吹きはがすものでも良い。Further, although the method of opening the electromagnetic valve 21 when the paper 5 is detected by the sensor 20 is shown, a small amount of air is constantly blown out from the nozzle 22 to assist the separation of the paper 5 and the steel strip 1. Therefore, when the paper 5 is detected, the opening degree of the electromagnetic valve 21 may be increased to remove the broken paper 5.

【考案の効果】[Effect of the device]

以上説明したように本考案によれば、紙の付着を検知した際には、ノズルより エアジェットを鋼帯表面に吹きつけ、鋼帯に付着した紙を吹きはがすことになり 、圧延ロール群への紙の侵入が防止される。この結果、紙の破断が発生しても圧 延作業は高速のまま継続でき圧延作業が効率化されると共に、圧延作業が一定ラ イン速度で行なわれるため製品の表面性状が一様になり品質が保たれる。また従 来の紙除去にともなう作業員の危険性が軽減される。 As described above, according to the present invention, when paper adhesion is detected, an air jet is blown from the nozzle onto the surface of the steel strip, and the paper attached to the steel strip is blown off. Of paper is prevented. As a result, even if the paper breaks, the rolling work can be continued at a high speed to improve the efficiency of the rolling work, and since the rolling work is performed at a constant line speed, the surface texture of the product becomes uniform and the quality is improved. Is maintained. It also reduces the risk to workers associated with conventional paper removal.
