Description

  The present invention relates to a roller guide device capable of adjusting the distance between guide rollers for guiding a rolled material.

  When the rolled material passes between the guide rollers, the space between the guide rollers is expanded. In order to prevent the rolling material from collapsing, the distance between the guide rollers can be adjusted by remote control to ensure optimum holding force. A roller guide device having an inter-surface adjusting mechanism that can be used has been proposed.

  For example, a rolling induction device (hereinafter referred to as “conventional example 1”) disclosed in Japanese Patent Application Laid-Open No. 2009-17239 is a pair of roller holders attached to a guide box so as to be slidable. A pair of guide rollers that are rotatably provided, a drive motor unit that can be operated remotely, a drive cylinder that is linked to the drive motor unit, and a center adjustment mechanism that is driven by the drive cylinder are provided. The drive motor unit includes a drive unit serving as a drive source, an adjustment screw to which driving force from the drive unit is transmitted, and an adjustment rod that is screw-coupled to the adjustment screw and that can be moved along with its rotation. It is comprised from the adjustment body which has. The drive cylinder has a cylinder rod that can be brought into and out of contact with the adjustment rod on one end side. The inter-center adjustment mechanism includes a rack, a gear wheel that meshes with the rack, and an eccentric shaft that interlocks with the gear wheel. The rack is connected to the other end side of the cylinder rod. The distance between the guide roller cores is adjusted through an eccentric shaft and a roller holder that move as the gear wheel rotates.

  Also in the roller guide disclosed in Japanese Patent Application Laid-Open No. 2011-92987 (hereinafter referred to as “conventional example 2”), an interval adjusting mechanism for adjusting the interval between the guide rollers is disclosed. This spacing adjustment mechanism is an eccentric roller pin that is attached to a guide box and has a pair of guide rollers with the center of rotation as the center of rotation, and a gear that is provided on the eccentric shaft portion above each eccentric roller pin. A drive cylinder provided in the guide box for adjusting the distance and holding force between the pair of guide rollers, and a spur gear attached to one end of a piston of the drive cylinder. The gears move back and forth due to the movement of the piston in the front-rear direction, and with this movement, the pair of gears rotate to the opposite side or to the opposite side to open and close the gap between the guide rollers and adjust the interval.

  Also in the roller guide disclosed in Japanese Unexamined Patent Publication No. 2007-125597 (hereinafter referred to as “Conventional Example 3”), a surface interval adjusting mechanism for adjusting the interval between the guide rollers is disclosed. That is, in the inter-surface adjusting mechanism, both center pinions that are in a reverse screw relationship with each other are rotatably attached, and each center pinion meshes with a gear. For this reason, the distance between the surfaces of the guide roller can be adjusted with the rotation of the gear meshing with the center pinion.

  Also in the rolling mill guide device (hereinafter referred to as “conventional example 4”) disclosed in Japanese Patent Application Laid-Open No. 2013-116491, an interval adjusting mechanism for adjusting the interval between the pair of guide rollers is disclosed. That is, in this distance adjusting mechanism, a pair of support arms is provided with a rotation shaft and an eccentric shaft, and these shafts operate in accordance with driving of a worm and a worm gear (or a rack and a pinion). For this reason, the pair of support arms are simultaneously rotated by the same angle by the distance adjusting mechanism, so that the inter-surface distance can be adjusted.

  However, in the conventional example 1 and the conventional example 2, since there is a limitation on the movement stroke of the rack, there is a case where it is not possible to cope with a new roll gap generated by changing the size of the rolled material only by adjusting the surface. In such a case, the rack teeth had to be changed and the efficiency was poor. Further, in Conventional Example 3 and Conventional Example 4, due to the characteristics of the worm and the worm gear (center pinion), even if a reaction force is applied to the roller from the passing rolling material, the roller cannot be adjusted while the surface is fixed. It was.

  That is, not only the suspension of the operation line due to the rack change and the manual movement of the roller guides decreases the operation efficiency, but the replacement work by the workers decreases the operation efficiency.

The provided impact relaxation part 20 is provided.

In FIG. 1 to FIG. 3, the inter-surface adjustment drive motor 13 and the rotary encoder 14 communicate with a control device in a management room (not shown) that can be remotely controlled.
For example, a hydraulic motor is used as the inter-surface adjustment drive motor 13. The rotational speed of the inter-surface adjustment drive motor 13 is adjusted by adjusting the amount of hydraulic oil supplied from a hydraulic hose (not shown) by remote control. The inter-surface adjustment drive motor 13 is fixed on a support case 21 attached to the right end surface of the guide box 5 in FIG. A worm 13 a is attached to the drive shaft of the inter-surface adjustment drive motor 13.
As shown in FIGS. 1 and 2, the rotary encoder 14 is provided on the support case 21 adjacent to the inter-surface adjustment drive motor 13. A transmission wheel 14 a is provided on the shaft of the rotary encoder 14. The transmission wheel 14 a meshes with the transmission wheel 13 b of the drive shaft of the inter-surface adjustment drive motor 13. The rotary encoder 14 can detect the rotation speed and the rotation direction of the center surface adjustment shaft 15 transmitted through the transmission wheel 13b and the transmission wheel 14a. The drive motor 13 is controlled.

In FIG. 1 and FIG. 4, the center surface adjusting shaft 15 is attached rotatably and forwardly or backwardly via a bearing 22 fixed to the side wall 5 a of the guide box 5. A slide body 23 is attached to the center surface adjustment shaft 15 shown in FIG. 4 with a gap on the tip side, and the center surface adjustment shaft and the slide body are rotatably connected to each other. Each slide body 23 is fitted in the bearing 22 so as to be movable, and serves as a guide means for smoothly moving the center surface adjusting shaft 15 forward or backward (back and forth movement).
Further, a stopper 24 for preventing forward movement of the center surface adjusting shaft 15 is provided on the tip side of the center surface adjusting shaft 15. The slide body 23 on the tip end side of the center surface adjusting shaft 15 is in contact with the stopper 24 so as to be separated.
The center surface adjusting shaft 15 has a receiving plate 26 rotatably attached to a rear end portion (right end portion in FIG. 4). The receiving plate 26 is movably fitted in the impact relaxation portion 20. In FIG. 4, a spline 15 a is formed at a position on the rear end side of the center surface adjusting shaft 15, and a worm wheel 25 is provided in mesh with the spline. The worm wheel 25 meshes with the worm 13a of the inter-surface adjustment drive motor 13 (FIG. 3). For this reason, the rotation of the worm 13a allows the center surface adjusting shaft 15 to move back and forth through the worm wheel 25 while rotating.

In the example shown in FIGS. 1 and 4, the transmission unit includes a center pinion 16 and a pair of idle gears 17.
The center pinion 16 is provided on the center surface adjusting shaft 15 and is disposed between the bearings 22. Specifically, the center pinion 16 is connected to the center surface adjusting shaft 15 by a hexagon socket sleeve.
The pair of idle gears 17 are arranged opposite to each other with the center surface adjusting shaft 15 interposed therebetween. The idle gears 17 on both the upper and lower sides in FIG. 1 mesh with the center pinion 16.

1 and 2, the front side guide guide eccentric gear 18 and the rear side (right side) eccentric gear 19 are both out of the side wall 5 a of the guide box 5. Are provided at the protruding end portions (lower end portions in FIG. 2) of the eccentric shafts 11 and 12 protruding in the direction. The eccentric shafts 11 and 12 move eccentrically around the center of each eccentric gear as the two pairs of eccentric gears 18 and 19 rotate.
In FIG. 1, the eccentric gear 18 and the eccentric gear 19 positioned on the upper side of the drawing are arranged to face each other along the rolling pass line. Similarly, the eccentric gear 18 and the eccentric gear 19 positioned on the lower side are arranged on the rolling pass line. Are arranged opposite to each other.

According to the example shown in FIG. 4, the impact relaxation unit 20 includes a cylindrical body 20 a and a disc spring 20 b housed in the cylindrical body.
The disc spring 20b is in contact with the receiving plate 26 at the rear end of the center surface adjusting shaft 15 and is always pressed toward the tip end side against the center surface adjusting shaft through the receiving plate. An elastic force is applied to the guide 6 in a direction in which the distance h between the surfaces of the guide roller 8 is reduced.

1 and 4, when the inter-surface adjustment drive motor 13 in the inter-surface adjustment mechanism 9 is actuated, the driving force is transmitted as a rotational force to the worm 13a, and the center inter-surface adjustment is performed through the worm wheel 25 engaged with the worm. Since the shaft 15 is rotationally driven, the pair of idle gears 17 meshing with the center pinion 16 of the center surface adjustment shaft also rotates, and the pair of eccentric gears 18 located on the left side of FIG. Since the pair of eccentric gears 19 positioned on the right side rotate simultaneously, the eccentric shafts 11 and 12 positioned eccentrically with respect to each of these pairs rotate eccentrically, and this eccentric rotation causes the opposite pair of sides. The guides 6 approach and separate while moving in the front-rear direction at the same time across the rolling pass line. It is possible to adjust the distance h between the surfaces of the guide roller 8 in conjunction with such approach and separation of the side guide 6.
Further, the rotation speed and rotation direction of the center surface adjusting shaft 15 are the worm wheel 25,
It is detected by the rotary encoder 14 via the worm 13a and the transmission wheel 13b, and the detection signal can be acquired by the control device of the management room. An operator in the management room can confirm the inter-surface h of the guide roller 8 based on the acquired detection signal.

The pass line alignment adjusting mechanism 4 will be described with reference to FIGS. 1 to 3 and FIG.
The pass line alignment adjusting mechanism 4 is a mechanism for adjusting the core of the guide roller 8 so as to follow the pass line of the rolled material. 1 and 3, the pass line alignment adjustment mechanism 4 is an adjustment axis drive motor 28 that is an adjustment axis drive means, and a position detection means of the roller guide body 1 (guide box 5) that is linked to the adjustment axis drive motor. A rotary encoder 29, a pass line alignment adjustment shaft 30 to which the rotational driving force from the adjustment shaft drive motor is transmitted, and a slide nut 31 engaged with the pass line alignment adjustment shaft are provided.
The adjusting shaft drive motor 28 and the rotary encoder 29 communicate with a control device in a management room that can remotely control them.
1 to 3, a worm 28 a and a transmission wheel 28 b are attached to the drive shaft of the adjustment shaft drive motor 28. A transmission wheel 29 a is attached to the shaft of the rotary encoder 29. The transmission wheel 29 a meshes with the transmission wheel 28 b of the adjustment shaft drive motor 28. The rotational speed and direction of the adjustment shaft drive motor 28 are detected by the rotary encoder 29 through the transmission wheel 29a and the transmission wheel 28b, and the detection signal is transmitted to the control device of the management room.
1 and 5, the pass line alignment adjusting shaft 30 is inserted at a position substantially in the middle of the saddle 2 so as to traverse the inside of the saddle in the lateral direction of FIGS. The pass line alignment adjusting shaft 30 is rotatably supported by bearings 32 at the left end and the right end in FIG. A gear wheel 33 is attached to the left end of the pass line alignment adjusting shaft 30 in FIG. 5, and this gear wheel meshes with a worm 28 a of the drive shaft of the adjustment shaft drive motor 28.
Further, as shown in FIG. 5, a storage hole 34 is opened downward from the upper surface of the saddle 2, and a pass line alignment adjusting shaft 30 passes through the storage hole in the left-right direction in the figure. A portion of the pass line alignment adjusting shaft 30 that straddles the storage hole 34 is a screw portion 30a. The threaded portion 30a meshes with the slide nut while penetrating through the slide nut 31 fixed to the guide box 5 so as to protrude from the bottom portion of the guide box 5 into the storage hole 34. The accommodation hole 34 has a space in which the slide nut 31 can move to the left and right in FIG.
Since the rotational force of the adjusting shaft drive motor 28 is transmitted to the pass line alignment adjusting shaft 30 via the worm 28a and the worm wheel 33, when the pass line alignment adjusting shaft rotates, the slide nut 31 meshing with the threaded portion 30a. However, the guide box 5 that fixes the slide nut 31 slides and the side guide 6 moves along with the movement of the guide box 5, so that the guide roller 8 moves. It is possible to adjust so that the path core is positioned along the path line.

Next, the usage will be described.
In the roller guide apparatus shown in FIGS. 1 to 3, the inter-surface adjustment mechanism 9 adjusts the inter-surface adjustment mechanism 9 so as to correspond to the size of the rolling material S (FIG. 6).
At the time of adjustment, the operator adjusts the rotation speed of the inter-surface adjustment drive motor 13 based on the detection signal of the rotary encoder 14 in the management room according to the amount of hydraulic oil to be supplied, and adjusts the rotation direction. The number of rotations and the direction of rotation of the inter-surface adjustment shaft 15 are determined, and at the same time, two sets of front and rear gears engaged with each of the idle gears via both idle gears 17 engaged with the center pinion 16 of the center-surface adjustment shaft. The number of rotations and the direction of rotation of the pair of eccentric gears 18 and 19 are adjusted, and finally, the distance between the side guides 6 facing each other and the distance h between the surfaces of the pair of guide rollers 8 are adjusted.
In the guide process of the rolling material S traveling in the direction of the arrow (left side) in FIG. 6, when both the front and rear ends Sa and Sb where the rolling material bulges pass between both guide rollers 8, a large load is applied to both guide rollers. For this reason, when these guide rollers are pushed outward, the pair of side guides 6 opens in the direction of the arrow in the figure, and when the eccentric shafts 11 and 12 move outward along with this opening, they are positioned on the upper side of the figure. The eccentric gears 18 and 19 are respectively rotated in the direction of the arrow (clockwise) around the central axis, and simultaneously the lower eccentric gears 18 and 19 are respectively rotated in the direction of the arrow (counterclockwise) about the central axis. As the eccentric gear rotates clockwise, the upper idle gear 17 turns counterclockwise, and at the same time as the lower eccentric gear rotates counterclockwise, the lower idle gear 17 turns clockwise. Since rotating the causes movement up and down of the idle gear 17 center plane between the adjustment shaft 15 through the center pinion 16 to the rear (Figure right) (backward). At this time, the center surface adjusting shaft 15 is retracted against the spring force of the disc spring 20 b (FIG. 4) in the impact relaxation portion 20 via the receiving plate 26.
When the end portions Sa and Sb of the rolled material S pass between the guide rollers 8, both guide rollers are released from the load, so that the center surface adjusting shaft 15 moves forward to the position at the time of adjustment by the elastic force of the disc spring 20b. To do. The return operation of the side guide 6 by the advancement of the center surface adjusting shaft 15 is opposite to the operations of the center pinion 16 under load, the upper and lower idle gears 17, the eccentric gears 18 and 19, and the eccentric shafts 11 and 12.

The product size change will be described while using the rolling rolls R1 and R2 as they are.
In the roller guide apparatus shown in FIG. 7 showing a state in which the adjustment between the roll gap and the surface of the guide roller 8 has been completed so as to correspond to a new rolled material by resizing, the adjustment-side rolling roll R2 is a solid line in FIG. From the position to the chain line position (the position of the solid line in FIG. 7), it moves downward in the figure (left side in FIG. 7), and is adjusted to an enlarged roll gap ga from the original roll gap g. Further, the pair of side guides 6 are moved away from the solid line position of FIG. 1 to the position of the solid line of FIG. By these adjustments, the core is aligned between the roll gap ga and the inter-surface ha.
Therefore, along with the size change, the vertical dimension of the rolled material S shown in FIG. 3, that is, the space h between the surfaces of the pair of guide rollers 8 is enlarged and adjusted to the space ha shown in FIG. 7, and both rolling rolls R1 shown in FIG. , R2 roll gap g is enlarged to the roll gap ga shown in FIG. 7, and a method for adjusting the core between the face-to-face ha and the roll gap ga will be described.
(Adjustment between guide roller faces)
In order to correspond to the rolling material whose size of the guide roller 8 is changed to a size larger than the rolling material S, the center pinion is driven by operating the inter-surface adjustment driving motor 13 and driving the center-surface adjusting shaft 15. 16 rotates, the space between the side guides 6 opens, and the space between the guide rollers 8 opens along with this opening operation. Therefore, the opening adjustment is stopped when the surface space h reaches the surface space ha shown in FIG.
In this inter-surface adjustment, data from the adjustment shaft drive motor 13 is sent to the rotary encoder 14, and therefore remote control is performed in the management room based on a detection signal from the rotary encoder.
(Adjusting the lead core to the guide roller)
By adjusting the size, the adjustment-side rolling roll R2 is moved to the lower side in FIG. 2 (left side in FIG. 7) to adjust the roll gap g to the target roll gap ga. This adjustment moves the rolling pass line to the left side of FIG.
Thereafter, by using the pass line alignment adjusting mechanism 4, the guide box 5 shown in FIG. 7 is adjusted to the left side of the figure by a half of the gap difference obtained by subtracting the original roll gap g from the adjusted roll gap ga (ga−g) / 2. To
For this purpose, the adjustment shaft drive motor 28 is driven to rotate the pass line alignment adjustment shaft 30, and the guide box 5 is moved from the position of the chain line in FIG. 7 through the slide nut 31 engaged with the pass line alignment adjustment shaft. Move to the position of the solid line, that is, (ga-g) / 2 to the left side of the figure.
The adjustment by the pass line alignment adjusting mechanism 4 is performed remotely in the management room based on the detection signal from the rotary encoder because the rotation speed of the adjustment shaft drive motor 28 is transmitted to the rotary encoder 29.
As a result, the face gap ha of the guide roller 8 faces the roll gap ga, and at the same time, the core is matched, and both the face-to-face adjustment and the roll gap adjustment are finished. After the adjustment, induction and rolling work of a new rolled material whose size has been changed is started.
As shown in the above example, as the adjustment order, it is not necessary to adjust the alignment between the surfaces of the guide roller 8 and adjust the roll gap g to the roll gap ga. As a result of the movement of the line to the left side of FIG. 7, the roller guide body 1 is also moved to the left side and the pass line is moved to the left side so that both rolling pass lines are matched. From the above, adjustment of the surface of the guide roller 8 in the roller guide body may be performed.

According to the illustrated roller guide device, when changing the size of the product, without adjusting the roller guide body 1 from the saddle 2, the inter-surface adjustment and roll gap adjustment of the guide roller 8 can be simplified by remote operation. The burden on the operator in the operation line can be reduced, and the non-operation time can be shortened, which contributes to the improvement of the operation efficiency.
According to the illustrated roller guide device, since it includes the impact relaxation portion 20 that imparts an elastic force in the direction of reducing the space between the guide rollers 8, dimensional abnormalities at the front and rear end portions Sa and Sb of the rolled material S are provided. Since the impact on the guide roller 8 by the portion can be avoided, the durability of the apparatus can be ensured.

  Both the inter-surface adjustment drive motor 13 and the adjustment shaft drive motor 28 are not limited to hydraulic motors. Further, the impact relaxation portion 20 in the guide roller 8 has a disc spring 20b built in the cylinder 20a. However, instead of the disc spring, the hydraulic oil is sealed in the cylinder, and the hydraulic pressure is maintained between the center surfaces by hydraulic pressure. An elastic force may be applied to the adjustment shaft 15 through a piston instead of the receiving plate 26.
