【発明の詳細な説明】
本発明は鋼帯の処理設備において、鋼帯の進行
方向を変更する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for changing the traveling direction of a steel strip in a steel strip processing facility.
鋼帯は幾つかの処理工程を通板されて製造され
るが、前の処理工程と次の処理工程が同一直線上
に配置されていない場合、前記前の処理工程から
次の処理工程に通板するさいは、鋼帯の進行方向
を変更する必要がある。 Steel strips are manufactured by being passed through several processing steps, but if the previous processing step and the next processing step are not arranged on the same straight line, the passing from the previous processing step to the next processing step is difficult. When plating, it is necessary to change the direction of progress of the steel strip.
このような進行方向変更は例えば第１図に示す
ような場合である。即ち第１図イの如く、鋼帯１
の第１処理設備Ａと第２処理設備B1とが90度向
きを異にする場合、あるいは第１図ロの如く、第
１処理設備Ａと、次工程の第２処理設備B2のそ
れぞれのパスラインがある距離だけずれている場
合である。 Such a change in direction of travel is, for example, as shown in FIG. That is, as shown in Fig. 1A, the steel strip 1
When the first processing equipment A and the second processing equipment B 1 are oriented 90 degrees apart, or as shown in Figure 1 B, the first processing equipment A and the second processing equipment B 2 of the next process are each This is a case where the path line of is shifted by a certain distance.
従来の鋼帯の進行方向変向手段は第２図に示す
フリーループ方式、第３図の如きツイストロール
方式等である。 Conventional means for changing the traveling direction of a steel strip include a free loop system as shown in FIG. 2, a twist roll system as shown in FIG. 3, and the like.
しかしながらフリーループ方式は鋼帯の通板速
度が高速になるに伴つて鋼帯のフリーループ部分
の揺動が激しくなり応用範囲は限られ、最近の高
速製造ラインでは１つのネツクである。 However, in the free loop method, as the steel strip passes through the steel strip at a higher speed, the free loop portion of the steel strip swings more violently, which limits its range of application, and is one of the drawbacks in recent high-speed production lines.
またツイストロール方式では、その機構上ロー
ルは大きな凸クラウン（楕円の円弧）を有してい
るから、鋼帯の進行方向変更時に、鋼帯の幅方向
で周速度が異なり、大きなスリツプを発生する。
従つて鋼帯の幅が極く狭い場合のみしか適用でき
ず問題であつた。 In addition, in the twist roll method, the roll has a large convex crown (elliptical arc) due to its mechanism, so when changing the direction of movement of the steel strip, the circumferential speed differs in the width direction of the steel strip, causing large slips. .
Therefore, this method was problematic because it could only be applied when the width of the steel strip was extremely narrow.
本発明はかかる従来装置の問題点を解決すべく
なされたもので、鋼帯の通板速度が高速であつて

In a device that changes the traveling direction of a steel strip while contacting a group of rotors, each of multiple helical curves with the same slope along the outer peripheral surface of a virtual cylinder has a diameter of the rotor. If d is the width of the rotor, b is the radius of curvature of the rotor cross section, and S is the slip ratio between the rotor and the steel strip, then S=b 2 /4ρd×100≦3(%) is satisfied. A plurality of rotors each having a shape of Steel strip traveling direction changing device 2, characterized in that the steel strip is supported by a child support and a curved surface formed by the envelope surface of the rotor is used as a traveling path of the steel strip. In a device that changes the rotor while in contact with the outer peripheral surface of the virtual cylinder, each of a plurality of spiral curves having the same slope along the outer circumferential surface of a virtual cylinder has the diameter of the rotor d, the width of the rotor b, and the radius of curvature of the rotor cross section ρ. If the slip rate between the rotor and the steel strip is S, then we can construct a plurality of rotors whose shapes satisfy S=b 2 /4ρd×100≦3(%) so that the rotors are orthogonal to the spiral curve. , and are arranged at intervals so as to be perpendicular to the diameter of the virtual cylinder, the rotation axis of the rotor group is supported by the outer periphery of the rotatable cylinder, and the rotor is formed by an envelope surface of the rotor. A device for changing the traveling direction of a steel strip, characterized in that a curved surface is used as a traveling path for the steel strip. a container is provided near the traveling path of the steel strip,

以下第４，５，６，７，８，９，１０，１１図
を参照して本発明を詳細に説明する。 The present invention will be described in detail below with reference to FIGS. 4, 5, 6, 7, 8, 9, 10, and 11.
第４図において１は鋼帯、２は回転子、３は回
転子の配列方方法を説明するための仮想円筒であ
る。 In FIG. 4, 1 is a steel strip, 2 is a rotor, and 3 is a virtual cylinder for explaining the method of arranging the rotors.
らせん曲線４は仮想円筒３面の周方向に対しφ

るため鋼帯１は滑かにらせん曲線４に沿つてその
進行方向を変更されるのである。 The spiral curve 4 is φ with respect to the circumferential direction of the three surfaces of the virtual cylinder.
It forms a helical angle along the three faces of the virtual cylinder. The rotors 2 are arranged at intervals with their rotational axes 2 -1 perpendicular to the spiral curve 4 and also perpendicular to the diameter direction of the virtual cylinder 3. Due to this arrangement, the direction of the rotor circumferential speed at the point where the rotor 2 contacts the steel strip 1 always coincides with the tangential direction of the helical curve 4, so the steel strip 1 smoothly changes its traveling direction along the helical curve 4. It will be done.
第５図は回転子２の配列についての理解を助け

る。 FIG. 5 is a developed view of the rotor arrangement along the spiral curve 4 to help understand the arrangement of the rotors 2. FIG. Assuming that the diameter of the virtual cylinder 3 is D and the winding angle of the spiral curve 4 with respect to the virtual cylinder 3 is α, the rotor 2 has a width B and a length αD/
The axis of rotation 2 -1 is connected to the steel strip 1 within the parallelogram of 2cosφ.
They will be arranged perpendicular to the direction of travel.
また該回転子２の配列は鋼帯１の進行方向から

く、スムーズに鋼帯１の進行方向を変更すること
ができる。 Furthermore, since the arrangement of the rotors 2 is a bird-like arrangement when viewed from the traveling direction of the steel strip 1, the tangential direction of the helical curve corresponding to the direction of the rotor circumferential speed and the direction of changing the traveling direction of the steel strip 1 mentioned above is Coupled with the fact that each rotor 2 is in agreement with the above, each rotor 2 can smoothly change the traveling direction of the steel strip 1 without receiving an unbalanced load.
次に本発明による装置についてさらに具体的に
説明する。 Next, the apparatus according to the present invention will be explained in more detail.
鋼帯１の進行方向を変更するさいは、第６図に

めなければならない。そこで鋼帯１に対する最大
曲げ応力は回転子２と鋼帯１とが接する点におい
て仮想円筒３の周方向（すなわち鋼帯の曲率が最
大となる方向）に生じる。 When changing the traveling direction of the steel strip 1, the diameter of the virtual cylinder 3 and the arrangement pitch of the rotors 2 must be determined so that the steel strip 1 does not bend as shown in FIG. Therefore, the maximum bending stress on the steel strip 1 occurs in the circumferential direction of the virtual cylinder 3 (that is, the direction in which the curvature of the steel strip is maximum) at the point where the rotor 2 and the steel strip 1 contact.

帯１を回転子２に沿つて捲きつかせるためには第
４図に示すような張力Ｔが必要である、このとき
張力Ｔの仮想円筒周方向分力はＴ／cosφとな
る。 FIG. 7 is a cross-sectional view perpendicular to the virtual cylinder axis, and in order to wrap the steel strip 1 along the rotor 2, a tension T as shown in FIG. 4 is required. The virtual cylinder circumferential direction component force is T/cosφ.

となる。 The arrangement pitch (angle) of rotor 2 is θ, the diameter is d,
If the virtual cylinder diameter is D, the thickness of steel strip 1 is h, the width is B, Young's modulus is E, and the helical angle is φ, the maximum bending stress is MAX becomes.
前記(1)式を用いて計算した最大曲げ応力〓MAX
の例を第８図に示す。 Maximum bending stress calculated using equation (1) above = MAX
An example is shown in FIG.
ここでの計算条件は鋼帯１の厚みｈ＝4.5mm、
ヤング率Ｅ＝2.1×104Kg／mm2、張力Ｔ／hB＝１
Kg／mm2とした。 The calculation conditions here are: thickness h of steel strip 1 = 4.5 mm;
Young's modulus E=2.1×10 4 Kg/mm 2 , tension T/hB=1
Kg/ mm2 .

鋼帯１の進行方向変更時に折れ曲りが生じないた
めの回転子２の配列ピツチθが仮想円筒直径に応
じて求められる。 Maximum bending stress to prevent bending in the steel strip 1 The MAX allowable value depends on the speed of the steel strip 1 and cannot be determined uniquely, but it is usually 2 to 3 times the yield stress (for example, 50 to 75 kg/ mm 2 ). from now,
The arrangement pitch θ of the rotor 2 to prevent the steel strip 1 from bending when changing its traveling direction is determined according to the virtual cylinder diameter.
次に回転子２の寸法であるが、まずその直径ｄ

だけ大きい方がよいけれども、相隣れる回転子２

い範囲
ｄ＜Ｄθ／2cosφ
で、できるだけ大きくすることが好ましい。 Next, regarding the dimensions of rotor 2, first, its diameter d
Considering the lifespan due to rotor 2 wear, it is better to make it as large as possible.
Since it is undesirable if the two contact with each other, it is preferable to make the range as large as possible so that d<Dθ/2cosφ does not come into contact with each other.
回転子２の幅ｂについては次のような条件を考
慮する必要がある。 Regarding the width b of the rotor 2, it is necessary to consider the following conditions.
回転子断面の曲率半径ρ（第９図参照）は、回
転子２と鋼帯１とが均一に接するためには、直径
Ｄ＋ｄなる仮想円筒３面上においてらせん曲線４
に直交する曲線の曲率半径に一致しなければなら
ないので、該曲率半径ρはρ＝Ｄ＋ｄ／２ｓｉｎ２φで
与えら
れる。 The radius of curvature ρ (see FIG. 9) of the rotor cross section is determined by the spiral curve 4 on the 3 plane of the virtual cylinder with diameter D + d in order for the rotor 2 and the steel strip 1 to be in uniform contact with each other.
The radius of curvature ρ is given by ρ=D+d/2sin 2 φ.
ところで鋼帯１は第９図において紙面に垂直方
向に進むので点Ａと点Ｂとにおける速度は同じで

いて異なるため滑りを生ずる。この滑り率Ｓは
Ｓ＝ｂ２／４ρ／ｄ＝ｂｓｉｎ２φ／２（Ｄ＋ｄ）
ｄ
で与えられる。 By the way, since the steel strip 1 advances in the direction perpendicular to the plane of the paper in FIG. 9, the speeds at points A and B are the same. However, since the circumferential speed of the rotor 2 is different at both points, slippage occurs. This slip rate S is S=b 2 /4ρ/d=bsin 2 φ/2(D+d)
It is given by d.
滑り率Ｓの許容限度は鋼帯にかかる張力、回転
子の材質、許容できる疵の程度等を考慮して３％
以下とする。たとえば冷間圧延に供される鋼帯の
場合もＳは３％以下とする。 The permissible limit for the slip rate S is 3%, taking into account the tension on the steel strip, the material of the rotor, the allowable degree of flaws, etc.
The following shall apply. For example, in the case of a steel strip subjected to cold rolling, the S content is set to 3% or less.
従つて通板される鋼帯１の許容滑り率Ｓにより
回転子２の幅ｂが決定される。 Therefore, the width b of the rotor 2 is determined by the permissible slip ratio S of the steel strip 1 being threaded.

ら軸受け（図示しない）を介して取付け、その保
守、点検を容易にしている。 FIG. 10 shows a specific embodiment of the traveling direction changing device according to the present invention. The rotor 2 is a rotor support,
For example, bearings (not shown) are placed at intervals on the helical curve 4 of the same slope on the helical surface frame 5.
It is arranged through. The envelope surface of the rotor 2 forms a helical curved surface, and since the steel strip 1 is passed along this helical curved surface, the direction of movement can be changed smoothly. Further, when the rotor 2 is disposed on the helical frame 5, it is attached from the back side of the helical frame 5 via a bearing (not shown) to facilitate maintenance and inspection.
なお、回転子２の軸受け（図示しない）は極力
滑かなものがよい。これは鋼帯１にかかる通板時
の張力がその幅方向に不均一な場合、鋼帯１と回
転子２との接触圧が不充分となる個所を生じスリ
ツプを起こすのを防ぐためである。 Note that the bearing (not shown) of the rotor 2 is preferably as smooth as possible. This is to prevent slippage from occurring where the contact pressure between the steel strip 1 and the rotor 2 is insufficient if the tension applied to the steel strip 1 during threading is uneven in its width direction. .
以上述べたように本発明によると鋼帯１の進行
方向を、折け曲り、スリツプ疵等損傷を生じるこ
となく、また鋼帯１の板幅が大であつてもまた小
さくてもスムーズに変更することができる。 As described above, according to the present invention, the traveling direction of the steel strip 1 can be changed smoothly without causing damage such as bending or slipping, and even if the width of the steel strip 1 is large or small. can do.
たとえば第１図に破線で示した部分に本発明の
装置を使用すれば、90度の方向転換あるいは進行
方向のシフトを達成できることが容易に理解でき
る。 For example, it is easy to understand that if the device of the present invention is used in the area indicated by the broken line in FIG. 1, a 90 degree change in direction or a shift in the direction of travel can be achieved.
次に鋼帯１の蛇行修正機能を有する進行方向変

隔をおいて配列されたものである。 Next, a traveling direction changing device having a meandering correction function for the steel strip 1 will be explained with reference to FIG. 11. In FIG. 11, reference numeral 6 denotes a cylinder that can be locked and rotated freely, and rotors 2 are arranged around the entire circumference of the cylinder 6. The rotor 2 is arranged so that the rotational axis 2 -1 of the rotor 2 is perpendicular to the spiral curve 4 along the 6th surface of the cylinder and also perpendicular to the diameter of the cylinder 6, so that the rotation axis 2 -1 of the rotor 2 is spaced apart. It is arranged in the following manner.
７は前記円筒６の回転用電動機で、８は鋼帯１
の蛇行量を検出する蛇行検出器例えばフオトセル
等であり、９は前記回転用電動機７の制御装置で
ある。なお１０は軸受けである。 7 is an electric motor for rotating the cylinder 6; 8 is a steel strip 1;
A meandering detector for detecting the amount of meandering is, for example, a photo cell, and 9 is a control device for the rotating electric motor 7. Note that 10 is a bearing.
次にこの作用について述べる。鋼帯１が蛇行す
ることなく通板されてきた場合は、円筒６は静止
状態で、回転子２の作用により、鋼帯１の進行方
向が変更される。 Next, we will discuss this effect. When the steel strip 1 is passed through without meandering, the cylinder 6 is in a stationary state, and the direction of movement of the steel strip 1 is changed by the action of the rotor 2.
そこで、いま鋼帯１に蛇行が生じて、鋼帯１の
進行方向変更後の方向を矢印Ｘの方向に修正する

９に入力され、回転用電動機７を作動させて、円
筒６を矢印Ａの方向に、蛇行検出量に応じて回転
させる。この円筒６の回転により、進行方向変更
後の方向は修正される。 Therefore, when a meandering occurs in the steel strip 1, in order to correct the direction after changing the traveling direction of the steel strip 1 to the direction of the arrow X, the meandering detection amount from the meandering detector 8 is input to the control device 9, The rotating electric motor 7 is operated to rotate the cylinder 6 in the direction of arrow A in accordance with the meandering detected amount. By this rotation of the cylinder 6, the direction after changing the traveling direction is corrected.
また鋼帯１の蛇行が前記と逆方向であつた場合
には、円筒６を逆方向に蛇行検出量に応じて回転
させると、進行方向変更後の方向が修正される。 Further, if the meandering of the steel strip 1 is in the opposite direction to that described above, by rotating the cylinder 6 in the opposite direction according to the meandering detection amount, the direction after the change in the traveling direction is corrected.
このように係止、回転自在な円筒６の全周に回
転子２を前述の如く配列すると、鋼帯１に蛇行が
生じても、進行方向変更後の方向を修正すること
ができる。 By arranging the rotors 2 as described above around the entire circumference of the cylinder 6 which can be locked and rotated in this manner, even if the steel strip 1 meanders, the direction after the direction of travel can be corrected.
鋼帯１の処理設備の配置を合理的、効率的なも

多く、本発明はこのような目的に対し極めて有益
なものといえる。 There are many cases where it is necessary to change the direction of movement of the processing equipment for the steel strip 1 in order to make the arrangement rational and efficient, and the present invention can be said to be extremely useful for such purposes.
なお本発明は鋼帯１のみならず、回転子２と帯
