ある。 When manufacturing steel plates, several processing steps must be performed. On the other hand, in recent years, as part of the rationalization of steel sheet manufacturing, various studies have been conducted on the serialization of multiple processing steps, that is, equipment and equipment. Because of this problem, attempts have been made to change the direction in which the steel plates travel in order to enable equipment layout that does not waste space. This is also necessary for the continuity of existing equipment.

しか適用できないという問題があつた。 Conventionally, a free loop method, a twist roll method, and the like have been proposed as means for changing the traveling direction of a steel plate. As shown in Fig. 1, the free loop method is such that two rolls 01 and 02 are installed with different orientations, and the steel plate 03 is given slack between them, and the orientation of the steel plate 03 is changed by twisting it. The twist roll method is a system in which a large number of rolls 04 are twisted and arranged, and these rolls 04 are
The orientation of the steel plate 03 can be changed by aligning the steel plate 03 along the line 4. However, in the above-mentioned free-loop method, the plate passing speed is limited by the swinging of the free-loop portion, that is, the slack portion, so the range of application thereof is limited. Also, in the twist roll method,
Technically, the roll 04 is provided with a large convex crown, so when the steel plate 03 moves direction is changed, the steel plate 04
There was a problem that the circumferential speed of the steel plate 03 differs in the width direction of the steel plate 3, which causes slips, so that it can only be applied to the narrow steel plate 03.

質の低下を来たすこととなり好ましくない。 Recently, however, a steel strip traveling direction changing device as shown in FIG. 3 has been proposed as a means for solving the problems of the conventional steel plate traveling direction changing means as described above. This device has a virtual cylindrical surface 05
A plurality of guide rollers 06 are arranged on the spiral curve of the steel plate 03, and the direction of the steel plate 03 is changed by moving the steel plate 03 in a spiral shape along these guide rollers 06. This device has a mechanical characteristic that the surface of the steel plate 03 on the entry side is on the lower side on the exit side. By the way, more scratches occur on both sides of the steel plate 03 than on the front side due to the guides and the like. Therefore, during the manufacturing process of steel plate 03,
It is not preferable for the front and back sides of the steel plate 03 to be reversed as described above, as this will result in a decrease in quality.

を目的とする。 The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to enable the traveling direction of a strip material to be changed without changing its front and back sides, and to impart self-centering properties to the strip material to prevent it from meandering. With the goal.

It is characterized in that it is rotatably arranged around an axis having a guide rotor, and the conical surface formed by the envelope surface of these guide rotating bodies is used as a traveling path of the strip material.

方向を変更させることとなる。 In FIG. 4 showing the basic concept of the present invention, 1 is a virtual conical surface as a virtual conical surface, 2 is a plurality of virtual spiral curves along the virtual conical surface 1, and the virtual conical curves 2 are at the point where they start winding around the virtual conical surface 1. It forms a helical angle of 1 with respect to the generatrix 3 of the conical surface 1. A plurality of guide rollers 4 as guide rotors are arranged on each helical curve 2 on the virtual conical surface 1 with their rotational axes 4a having an inclination angle θ with respect to an axis orthogonal to the helical curve 2. The inclination angles θ of the rotating shafts 4a of the guide rollers 4 on each helical curve 2 other than the central part, that is, the rotation shafts 4a of the guide rollers 4 on both sides with respect to the center line G, are set so as to face the center line G. They are arranged almost line-symmetrically with respect to line G. The belt-shaped steel plate 5 is moved along the conical curved surface formed by the envelope surface of the guide roller 4 as a traveling path. By arranging the guide rollers 4 in this way, the direction of the circumferential speed of the rollers at the point where the guide rollers 4 contact the steel plate 5 coincides with the tangential direction of the helical curve 2 in the roller group on the center line G, but In the roller groups on both sides sandwiching the , the inclination angle θ is set so that the rotation axis 4a is directed toward the center line G with respect to the axis perpendicular to the spiral curve 2. Therefore, the roller rotation direction of these roller groups is set at the inclination angle θ. As a result, a lateral force toward the center acts on the steel plate 5. As a result, the steel plate 5 is pushed toward the center line G from both sides and a self-aligning function occurs, so that the steel plate 5 is fed without meandering and its direction of movement is changed.
図中、Ｂは帯状鋼板５の幅である。 In the figure, B is the width of the strip steel plate 5.
第５図には第４図を展開した様子を示す。ガイ
ドローラ４群は仮想円錐面１と鋼板５とが接触し
始める母線３と角度1をなした幅Ｂを持つ帯状
台形ACFEの中にあり、その回転軸４ａは鋼板５
の進行方向に直交する軸に対して中心線Ｇに向う
よう傾斜角がθとなるよう配列されている。 FIG. 5 shows an expanded version of FIG. 4. The 4 groups of guide rollers are located in a band-shaped trapezoid ACFE having a width B that forms an angle 1 with the generatrix 3 where the virtual conical surface 1 and the steel plate 5 begin to contact, and the rotation axis 4a thereof
They are arranged so that the inclination angle is θ toward the center line G with respect to the axis perpendicular to the direction of travel.
尚、帯状台形ACFEを外れたところの鋼板５の
部分は平面となるが、この部分にもガイドローラ
を設ける場合にはガイドローラの回転軸が上記同
様の傾斜角をもつよう説定すれば良い。 Note that the part of the steel plate 5 outside the band-shaped trapezoid ACFE is a flat surface, but if a guide roller is provided in this part as well, the rotating shaft of the guide roller should have the same inclination angle as above. .
次に、進行方向の変更角度と仮想円錐面１の頂
角αとの関係について検討する。 Next, the relationship between the change angle of the traveling direction and the apex angle α of the virtual conical surface 1 will be considered.
まず、第４図を参照して、仮想円錐面１への入
側と出側とで鋼板５の進行方向が90゜をなす場合
（β＝90゜の場合）を考えると、仮想円錐面１への
鋼板５の入側５ａと出側５ｂにおける鋼板５と母
線３とのなす角度1，2との和は90゜となるため、
第５図より仮想円錐面１の展開図における頂角α

板５の出側５ｂの進行方向を入側５ａと同一平面
においてその進行方向に対して角度βだけ変更し
たい場合には、仮想円錐面１の展開図の頂角をα
＝βに選び、その仮想円錐面に鋼板５を１周巻き
付ければよいことになる。 First, with reference to FIG. 4, if we consider the case where the advancing direction of the steel plate 5 forms 90 degrees between the entrance and exit sides of the virtual conical surface 1 (when β = 90 degrees), the virtual conical surface 1 Since the sum of the angles 1 and 2 between the steel plate 5 and the generating line 3 at the entrance side 5a and exit side 5b of the steel plate 5 is 90°,
From Fig. 5, the apex angle α in the developed view of the virtual conical surface 1
It can be seen that the angle is also 90°. Considering the same way, if you want to change the traveling direction of the exit side 5b of the steel plate 5 by an angle β with respect to the traveling direction on the same plane as the entrance side 5a, the apex angle of the developed view of the virtual conical surface 1 should be α
= β and wrap the steel plate 5 around the virtual conical surface once.
もちろんα≠βの場合でも、仮想円錐面に巻き
付き付ける量を調整することにより、即ち仮想円
錐面上を丁度１周ではなく、１周以上又は１周以

５の入出側の両進行方向のなす角度を見かけ上β
に選ぶことにより、鋼板５の進行方向を任意に設
定することができる。ただし、この場合は鋼板５
は入側５ａと出側５ｂとは同一平面にないため、
鋼板５を方向転換した後、必要に応じて鋼板５の
進行方向を水平、垂直等に再修正する必要がある
ことは言うまでもない。 Of course, even in the case of α≠β, by adjusting the amount of wrapping around the virtual conical surface, that is, by wrapping it around the virtual conical surface more than one time or less than one time, instead of just one time around the virtual conical surface. The apparent angle between the two advancing directions on the entrance and exit sides of the steel plate 5 is β
By selecting , the traveling direction of the steel plate 5 can be arbitrarily set. However, in this case, the steel plate 5
Since the entrance side 5a and the exit side 5b are not on the same plane,
It goes without saying that after changing the direction of the steel plate 5, it is necessary to readjust the traveling direction of the steel plate 5 to horizontal, vertical, etc. as necessary.
又、仮想円錐面１での鋼板５の入出側を同一平
面上に選ぶ必要がない場合には、仮想錐状面を、
第６図に示すように底面１ａがらせん曲線をなす
ようならせん円錐面１′として、ここに鋼板５を
巻き付けても同様の効果を得ることができる。 In addition, if it is not necessary to select the entrance and exit sides of the steel plate 5 on the same plane on the virtual conical surface 1, the virtual conical surface is
As shown in FIG. 6, the same effect can be obtained even if the bottom surface 1a is formed into a spiral conical surface 1' forming a spiral curve, and the steel plate 5 is wound around the spiral conical surface 1'.

れば、それぞれのガイドローラ４に作用する力
FL，FRとの間には次式が成り立つ。 In this way, the rotating shaft 4a of the guide roller 4 is connected to the steel plate 5.
By providing an inclination angle θ toward the center line G with respect to the axis Z perpendicular to the traveling direction of the steel plate 5, the force acting on the steel plate 5 becomes as shown in FIG. That is, if the force that moves the steel plate 5 forward is F, and it is supported by a pair of guide rollers 4 sandwiching the center line G, the force acting on each guide roller 4 is
The following equation holds true between F L and FR .
Ｆ＝FL＋FR
このとき、ガイドローラ４の回転軸４ａが軸Ｚ
に対して傾斜角θが０であれば、通常、軸Ｚ方向
の力は作用しないが、傾斜角θが設けてあるので
側方力fL，fRがそれぞれガイドローラ４の回転軸
４ａ方向に向つて作用するとともにその値は次式
で表わすことができる。 F=F L +F R At this time, the rotating shaft 4a of the guide roller 4 is aligned with the axis Z.
If the inclination angle θ is 0, normally no force will act in the direction of the axis Z, but since the inclination angle θ is provided, the lateral forces f L and f R will be applied in the direction of the rotation axis 4a of the guide roller 4, respectively. The value can be expressed by the following equation.
fL＝FL・sinθ，fR＝FR・sinθ
したがつて、鋼板５の進行方向と直角方向には
求心力f′L，f′Rが生じることとなり、その値は次
式となる。 f L = F L · sin θ, f R = F R · sin θ Therefore, centripetal forces f' L and f' R are generated in the direction perpendicular to the traveling direction of the steel plate 5, and their values are expressed by the following equation.
f′L＝FL・sinθ・cosθ，f′R＝FR・sinθ・cosθ
今、中心線Ｇに対し鋼板５の中心がずれたとす
れば左右の求心力f′L，f′Rに差が生じ、例えば左
側に鋼板５が片寄つた場合にはf′L＞f′Rとなり鋼
板５に対してf′L−f′Rの求心力が作用することと
なり鋼板５は右側に戻され、中心に戻つたときに
f′L＝f′Rとなりバランスが取れて中心位置を保つ
こととなる。すなわち、自己調心機能を有するこ
ととなる。 f′ L = F L・sinθ・cosθ, f′ R =F R・sinθ・cosθ Now, if the center of the steel plate 5 is shifted with respect to the center line G, there will be a difference between the left and right centripetal forces f′ L and f′ R. For example, if the steel plate 5 is shifted to the left side, f′ L > f′ R and a centripetal force of f′ L − f′ R will act on the steel plate 5, and the steel plate 5 will be returned to the right side and centered. when I get back
f′ L = f′ R , and the balance is maintained and the center position is maintained. In other words, it has a self-centering function.

仮想円錐用フレーム６上に取付けている。 FIG. 8 shows a specific example of the traveling direction changing device according to the present invention. A plurality of virtual cone frames 6 are arranged along the generatrix 3 of the virtual cone surface 1 via bearings (not shown). The guide roller 4 is supported on the virtual cone frame 6 so that its rotation axis 4a has an inclination angle θ with respect to an axis orthogonal to the spiral curves 2 on the plurality of spiral curves 2 along the virtual cone surface 1. However, in this specific example, four groups of guide rollers arranged on the same generatrix 3 are assembled into the base 7 to form a guide roller assembly 8, which is mounted on the virtual cone frame 6.

検は容易となる。 The envelope surface of the guide roller 4 forms a spiral surface, and the steel plate 5 is threaded along this spiral surface, so that the traveling direction can be changed smoothly without changing the front and back sides, and the steel plate 5 can be smoothly changed from the guide roller group 4. Since the steel plate 5 has a self-centering function that always positions the steel plate 5 at the center by the centripetal force, the steel plate 5 does not meander. Further, in this device, since the four groups of guide rollers are assembled, maintenance and inspection thereof are easy.

Further, in the above specific example, a regular cone is used as an example of the virtual conical surface, but it goes without saying that the present invention may be applied to a general cone or pyramid that is not a regular cone. Furthermore, in the above specific example, the guide roller 4 whose rotating shaft 4a has an inclination angle θ with respect to the axis perpendicular to the spiral curve 2 is used as the guide rotor, but in addition to that, the guide roller 4 whose surface has a strip material and a point or It is also possible to use a spherical object or the like that makes surface contact.
