DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal looper for a continuous strip processing line having an inlet looper and an outlet looper.

[0002]

2. Description of the Related Art In a continuous strip processing line for continuous annealing, plating equipment, pickling equipment, etc., there is a welding operation of a leading coil and a trailing coil in an inlet section, and the strip is temporarily decelerated and stopped. Also, in the output section, the strip is temporarily decelerated when the winding coil is switched. For this purpose, an inlet horizontal looper device and an outlet horizontal looper device are provided in each line, so that the central section can be operated continuously.

[0003] As shown in FIG. 3, the inlet horizontal looper device 27 and the outlet horizontal looper device 28 can store the strip 1 independently of each other. Therefore, each of the looper devices has a moving deflector roll 4
, And wires 25 and wire drums 26 for moving the carts, and wire drum rotation driving devices 23 and 24 are provided.

[0004]

However, in the above-mentioned prior art, two moving trucks are required for the entrance horizontal looper device and the exit horizontal looper device , and two sets of wires for moving the truck are required. A moving device was needed. Furthermore, from the viewpoint of the installation space, the installation space for the two movable trolleys and the wire drum for the moving device requires as much as ten and several meters in the line direction, so that the storage amount of the looper must be restricted. There was a point.

[0005] The present invention has been devised in order to solve such disadvantages of the prior art, and a main object thereof is to share a deflector roll moving carriage of an entrance horizontal looper device and an exit horizontal looper device. An object of the present invention is to provide a horizontal looper device for a continuous strip processing line that has a simple device configuration and requires no installation space.

[0006]

SUMMARY OF THE INVENTION According to the present invention, it is an object of the present invention to provide a moving deflector roll for an incoming horizontal looper device and a moving deflector roll for an outlet horizontal looper device. This is achieved by providing a cart.

[0007]

[Function] A deflector roll moving carriage for sharing and moving the moving deflector roll for the entrance side horizontal looper device and the moving deflector roll for the exit side horizontal looper device is provided, so that the deflector roll movement of the entrance side and exit side horizontal looper devices is provided. The trolley can be shared, and only one is needed. And
By controlling the tension of the strip entry side section and egress section, the cart can be moved. Therefore, there is no need for a moving device using two sets of wires for moving the moving cart. Further, it is possible to reduce an installation space of ten and several meters in the line direction for installing the moving device.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows the entire line layout in consideration of the horizontal looper device according to the present invention. In a normal operation, the transported strip 1 enters in the direction of the arrow, and the payoff reel 16, No. 1 deflector roll 4-1, fixed deflector roll 5, movable cart 4 of movable cart 4 via 1 bridle roll 2, fixed deflector roll 3
No. 4-2, fixed deflector roll 6, No. It is fed through a two bridle roll 7 and a fixed deflector roll 8 to a central section 19.

The strip 1 discharged from the central section 19 is provided with a fixed deflector roll 9, no. No. 3 bridle roll 10, fixed deflector roll 11, deflector roll 4-3 of mobile trolley 4, fixed deflector roll 12, deflector roll 4-4 of mobile trolley 4, fixed deflector rolls 13, 14, no. 4
Winding is performed on the tension reel 17 through the bridle roll 15.

Next, the basic concept of the operation operation will be described below. First, during normal operation, the entrance section 3
7 , the strip speed is the same for the center section 19 and the exit section 38, and the moving cart 4 of the horizontal looper device is used.
Is stopped at the home position shown in FIG.

[0011] Next, when welding the coil entry side section 37, the strip entry side section 37 is stopped. At the same interrupts the strip winding tension reel 17 of the exit-side section 38 at the same time, the delivery side section 38
The strip also stops . At that time, the entry section 37
Is higher than the strip tension of the outgoing section 38 , the carriage 4 is moved in the direction of the incoming section, and the strip of the incoming section 37 is moved to the central section.
Release to 19 . Thus, in the central section 19 the strip is threaded at normal line speed.

Next, when the coil of the output section 38 is switched, the strip of the output section 38 is switched.
Decelerate to the fly speed. At the same time the entry section 37
Also decelerates, but the central section 19 operates at a steady line speed. At that time, the tension of the strip of the entry section 37 is made higher than the strip tension of the exit section 38 , and the carriage 4 is moved in the direction of the entry section to move the strip of the entry section 37 to the central section 19.
Release .

Incidentally, the melting of the coil in the inlet section 37 is performed.
Contact or coil switching in outlet section 38 is completed.
Therefore, the mobile trolley 4 is close to the traveling limit in the entry section direction.
At the moment, the strike in the entry section
The lip is almost discharged. Enter in this state
Center the strip passing speed in the side and exit sections
The outgoing section as well as the section
The strip tension of the incoming section to the strip tension of the incoming section.
If higher, the mobile trolley 4 moves toward the exit section
And return to normal operation when it reaches the home position.
Then, the state shown in FIG. 1 is obtained again.

The tension adjustment of the strip is performed in the entry section.
In No. 37 , No. 1 and No. 1 2 bridle rolls 2,
No. 7 in the exit section 38 . 3 and No. 3
This is performed with four bridle rolls 10 and 15. The tension detection for adjusting the tension is performed by a tension meter 36 provided on the fixed deflector rolls 5 and 12. Regarding the determination of the horizontal looper capacity for shared looper, entry side sections
Down time for coil welding in
Of coil switching time for coil switching
Whichever is longer is determined.

[0015] The movable cart is basically an entrance / exit section.
Although it adapted to move by the difference of the strip tension down 37 and 38, in the case of operating conditions that the tension variations in the strip is not stabilized, in order to ensure the movement of the movable carrier, auxiliary drive mechanism to the movable carrier May be provided. FIG. 2 shows an example of the auxiliary drive mechanism. In this case, the pinion 32 is rotationally driven by the auxiliary driving motor 30 and meshes with the rack 33 installed on the ground to perform the auxiliary driving of the movable cart. Entry section and exit section
A shock absorber 31 is provided to alleviate sudden fluctuations in strip tension of the components 37 and 38 .

[0016]

According to the present invention, the conventional entrance looper,
By using a common exit looper, it is possible to expect significant effects such as a significant reduction in the weight of mechanical products, the elimination of electrical components, a reduction in building space, and a reduction in civil engineering costs.
