The amount of metal strip 2. In addition, if the looper wire 15a is successively released by the looper winch 20, the looper 17 is moved toward the inlet side by the pulling force acting on the metal strip 2 by the winding drive of the coil 2a. Therefore, even if no pulling force is applied, the interval between the winding roller 8 and the fixed roller 7 will be narrowed, thereby reducing the amount of metal strip 2 accumulated in the horizontal looper device 6 .

FIG. 5( a ) is a front view of the main support roller car 26 , and FIG. 5( b ) is a side view of the main support roller car 26 . The support rollers 9 are rotatably provided between the long side portions of the relatively long rectangular frame 21 in the up-down direction, and a plurality of supporting rollers 9 are arranged at appropriate intervals in the up-down direction. Near the center of the frame 21 in the up-down direction, there are bases 22 protruding on both sides toward the outside of the frame 21 along the axial direction of the support roller 9. The support roller 9 is a roller that supports the metal strip 2 from below to prevent the slack of the metal strip 2 that spans between the fixed roll 7 and the winding roll 8, and its diameter is larger than the fixed roll 7 and the winding roll 8. The diameter is small, and in order to support the metal strip 2 tensioned above and below the fixed roll 7 and the winding roll 8, there are twice the number of the fixed roll 7 and the winding roll 8.

Wheels 23 that support the frame 21 and can travel are respectively arranged on the side surfaces of the base 22, and the first wire 24a and the second wire 24b stretched in the horizontal direction are arranged side by side on the base 22 respectively. The pulley 25a and the second pulley 25b. Among them, the support roller 9 , the frame 21 , the base 22 , the wheel 23 , the first pulley 25 a and the second pulley 25 b correspond to the main support roller car 26 .

The main support roller car 26 mounts the wheels 23 on the running rail 18, and is supported at the center of gravity with the frame 21 erected by the triangular member 37 so as to be movable in the conveying direction. The plurality of wheels 23 are arranged in the conveying direction, and are configured so as not to tip over in the conveying direction. In addition, the running track 18 can share the running track 18 of the looper car 17 . Additional tracks can also be set. The upper half of the main support roller unit 26a constituted by the frame 21 is located above the upper surface 18a of the running rail 18, and the lower half of the main supporting roller unit 26a is located above the running rail 18. 18a is the lower position.

On the left and right two first pulleys 25a on the base 22, on the outlet side of the frame body 21, respectively, at a winding angle of 90°, there are outlets arranged on the outlet side of the horizontal looper device 6. The first wire 24a that can be drawn out from the side winch 27 and can be wound, and the end portion of the first wire 24a is fixed to the fixing portion 36 on the outlet side of the horizontal looper 6 .

On the left and right second pulleys 25b on the base 22, on the inlet side of the frame body 21, the inlets provided on the inlet side of the horizontal looper device 6 are respectively wound at a winding angle of 90°. The second wire 24b that can be drawn out from the side winch 28 and can be wound, and the end portion of the second wire 24b is fixed to the fixing portion 38 on the inlet side of the horizontal looper device 6 .

The main backup roll car 26 moves toward the exit side by winding up the first wire 24a by the exit winch 27, and feeding out the second wire 24b by the entrance winch 28. Further, the second wire 24b is wound by the inlet side winch 28, and the first wire 24a is successively drawn out by the outlet side winch 27, thereby moving the main backup roll car 26 toward the inlet side.

The horizontal looper device 6 of the present embodiment is provided with four auxiliary support roller cars 29, which are connected to the looper car 17 driven by the looper car winch 20, the outlet side winch 27 and the inlet side winch. The main support roller car 26 driven by 28 and the support column 11 provided with the fixed roller 7 are passively moved. The sub-backup roll car 29 is different from the main back-up roll car 26 in that the first and second pulleys 25 a and 25 b are not provided, and the other configuration is the same as that of the main back-up roll car 26 . The backup rollers 10 provided on the sub-backup roller carriage 29 are equivalent to the backup rollers 9 of the main backup roller carriage 26 . In addition, in the sub-back-up roll car 29 , the sub-back-up roll unit 29 a in which the plurality of back-up rolls 10 are provided on the frame 33 corresponds to the main back-up roll unit 26 a of the main back-up roll car 26 . The four sub-backup roller carts 29 are connected between the pillar 11 provided with the fixed roller 7 and the main back-up roller cart 26, and the wheels 30 provided on the side surfaces of the base 34 are placed on the running rails 18, respectively. Side by side in a supported state at the center of gravity.

The main support roller car 26 and the four auxiliary support roller cars 29 are connected with the adjacent support roller cars 26 and 29 by the connecting chain 31 (refer to FIG. 2 , FIG. 3 , and FIG. 6 ). 26 When traveling toward the exit side by the exit side winch 27 and the entrance side winch 28, when the connecting chain 31 is tensioned, the adjacent sub-support roller carts 29 are pulled in sequence to move toward the exit side (refer to FIG. 6(b) → 6(a)), when moving toward the entrance side, the main support roller cart 26 contacts the adjacent sub support roller cart 29, pushes the sub support roller cart 29 while moving toward the entrance side, and by this movement It moves toward the side of the support|pillar 11 provided in the entrance side while increasing the number of the auxiliary|assistant support roller 29 accompanying it (refer FIG.6(a)→FIG.6(b)).

At this time, the looper car 17 and the main back-up roll car 26 are driven by the looper car winches 20 , the outlet side winches 27 , and the inlet side winches 28 , which are different from each other. In addition, the distance C between the looper car 17 and the main support roller car 26 is measured by the position detector 39 provided thereon.

Furthermore, in FIG. 2 , a position detector 39 (eg, a beam sensor of a light-receiving type) is installed on both the looper car 17 and the main support roller car 26 , but the looper car 17 may also be installed. A structure in which a sensor of a reflection type or an eddy current type is installed in any one of the main support roller cars 26 .

As shown in FIG. 6( b ), after the looper cart 17 starts to move toward the exit side, when the position detector 39 detects that a predetermined distance interval (eg, the length of the connecting chain 31 ) is reached, the main support roller cart 26 moves to the exit side. The looper trolley 17 starts to move toward the exit side at the same speed as the looper trolley 17 and travels at a predetermined distance interval. When all the link chains 31 of the backup roller trolleys 26 and 29 become tensioned, the main backup roller trolley 26 stops, and The looper 17 stops at a moment when the distance is farther than a predetermined distance interval (in FIG. 2, the position of S). Such control is performed according to the distance (interval C) measured by the position detector 39 . Furthermore, the exchange of the roll 2a has been completed so far.

Further, as shown in FIG. 6( a ), after the looper 17 starts to move toward the entrance from the stop state on the exit side, it is also when the position detector 39 detects that a predetermined distance interval is reached (for example, the looper 17 is about to move Before contacting the main back-up roll car 26), the main back-up roll car 26 starts to move toward the entrance side at the same speed as the looper car 17, so that the looper car 17 and the main back-up roll car 26 can be made not in contact with each other. state moves.

In this way, according to the horizontal looper device 6 of the present embodiment, the looper car 17 that moves in order to change the interval between the fixed roller 7 and the winding roller 8 and the The main support rollers 26 of the support rollers 9 of the metal strip 2 between the two are driven independently and can move without contacting each other, so the action of the looper 17 that applies tension to the metal strip 2 will not be supported by the main support. The movement of the roller car 26 is affected.

More specifically, since the looper cart 17 does not collide with the main back-up roller cart 26 and is impacted, in addition, the looper cart 17 does not pull the main back-up roller cart 26, so there is no impact at the beginning of pulling, so The tension of the metal strip 2 is not easily changed. Therefore, a horizontal looper device 6 that suppresses fluctuations in the tension of the metal strip 2 can be provided.

In addition, in addition to the main support roll car 26 , the sub-backup roll car 29 having the support roll 10 supporting the metal strip 2 is provided, so that the bending of the metal strip 2 can be suppressed more effectively. In addition, the secondary support roller cart 29 is moved by the traction of the main support roller cart 26 , so the movement of the secondary support roller cart 29 also hardly affects the movement of the looper cart 17 . Therefore, it is possible to provide a horizontal looper device 6 capable of suppressing both the bending of the metal strip 2 and the fluctuation of the tension of the metal strip 2 .

In addition, since the winding roller unit 17a of the looper car 17, the main backup roller unit 26a of the main backup roller car 26 and the sub backup roller unit 29a of the sub backup roller car 29 are supported at the positions of the respective centers of gravity, Therefore, the winding roller unit 17a, the main backup roller unit 26a, and the sub-backup roller unit 29a can be moved in a more stable state. For example, compared with the case where wheels are provided on the upper end or the lower end of the winding roller unit 17a, the main backup roller unit 26a, and the sub backup roller unit 29a for movement, the shaking can be suppressed smaller. Therefore, a horizontal looper device 6 capable of further suppressing fluctuations in the tension of the metal strip 2 can be constructed.

At this time, by the driving of the main back-up roller cart 26, although the sub-back-up roller cart 29 collides in sequence, or is pulled by the connecting chain 31 and moves while being collided, the gap between the fixed roller 7 and the winding roller 8 is not affected. The tension of the metal strip 2 does not change, and it will not cause adverse effects on the product. This situation has actually been confirmed.

In addition, the looper car 17 and the main back-up roll car 26 are connected to the looper wire 15a, the first wire 24a and the looper wire 15a, the first wire 24a and As the second wire 24b moves, for example, like a self-propelled looper or a main back-up roller vehicle equipped with a motor, the motor or the drive unit of the motor does not move, and the winches 20, 27, 28 are the driving source. always in a fixed position. Therefore, it can be used as the horizontal looper device 6 which is easy to repair or maintain.

In addition, the above-mentioned embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the interpretation of the present invention. The present invention can be changed or improved as long as it does not exceed the essential content, and it is needless to say that equivalents are also included in the present invention.
