Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a strip continuous processing line for continuous annealing, plating equipment, pickling equipment, etc., there is welding work of a preceding coil and a following coil in an entry side section, and the strip is temporarily decelerated and stopped. Also, in the output side section, the strip is temporarily decelerated when the winding coil is switched. Therefore, an inlet horizontal looper device and an outlet horizontal looper device are provided in the line so that the central section can be continuously operated.

As shown in FIG. 3, the entrance horizontal looper device 27 and the exit 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
There are provided movable carriages 21 and 22 for moving, a wire 25 for moving the movable carriage, a wire drum 26, and wire drum rotation drive devices 23 and 24.

[0004]

However, in the above-mentioned prior art, two moving carriages are required on the entrance side and the exit side, and a moving device using two sets of wires for moving the carriages is required. It was Further, from the viewpoint of installation space, the installation space for the two moving carriages and the wire drum for the moving device requires a dozen meters in the line direction.
Therefore, there is a problem that the storage amount of the looper must be restricted.

The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to share a deflector roll moving carriage for the entrance side horizontal looper device and the exit side 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 structure and does not occupy an installation space.

[0006]

According to the present invention, such a purpose is to move a deflector roll that shares and moves a moving deflector roll for an incoming horizontal looper device and a moving deflector roll for an outgoing horizontal looper device. This is achieved by providing a dolly.

[0007]

[Function] Since the deflector roll moving carriage that shares and moves 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, the deflector rolls of the entrance and exit side horizontal looper devices are provided. A mobile trolley can be shared, and only one is required. And
By controlling the tension of the strip on the input side and the strip on the output side,
The mobile carriage can be moved. Therefore, a moving device using two sets of wires for moving the moving carriage is unnecessary. Further, it is possible to reduce the installation space for installing the moving device by a dozen meters in the line direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An 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. The strip 1 to be transferred in the normal operation enters in the direction of the arrow, and the payoff reel 16, No. 1 Bridle roll 2, fixed deflector roll 3, deflector roll 4-1 of movable carriage 4, fixed deflector roll 5, movable carriage 4
Deflector roll 4-2, fixed deflector roll 6, No. 2 through a bridle roll 7 and a fixed deflector roll 8 to a central section 19.

Further, the strip 1 discharged from the central section 19 has a fixed deflector roll 9, No. No. 3 bridle roll 10, fixed deflector roll 11, deflector roll 4-3 of movable carriage 4, fixed deflector roll 12, deflector roll 4-4 of movable carriage 4, fixed deflector rolls 13, 14, No. Four
The tension reel 17 passes through the bridle roll 15 and is wound up.

Next, the basic concept of operation operation will be described below. First, during normal operation, the entry side section,
The strip speed is the same in both the central section and the exit section, and the moving carriage 4 of the horizontal looper device is stopped at the home position shown in FIG.

Next, when welding the coil of the entry side section, the entry strip is stopped. At the same time, the take-up tension reel strip winding is interrupted, and the take-out strip is almost stopped. At that time, the tension of the strip on the entrance side is made higher than the tension of the strip on the exit side, and
To the entry side and eject the entry side strip into the central section. Therefore, the strips are threaded in the central section at normal line speeds.

Next, when the coil of the output side section is switched, the output side line is decelerated, and the input side section and the central section are operated at a constant line speed. At that time,
The tension of the strip on the outgoing side is made higher than the tension on the strip on the incoming side, and the movable carriage 4 is moved to the outgoing side to store the strip on the incoming side.

When the traveling carriage reaches the traveling limit of the exit side, the entrance line is stopped, the tension of the strip on the entrance side is made higher than the tension of the strip on the exit side, the carriage is moved to the entrance side, and the strip is removed. To the central section.

The tension of the strip is adjusted to N
o. 1 and No. 2 Bridle rolls 2 and 7 are used, and No. 2 on the exit side. 3 and No. 4 bridle rolls 10,1
Do in 5. The tension for tension adjustment is detected by the tension meter 36 provided on the fixed deflector rolls 5 and 12. Regarding the determination of the horizontal looper capacity, because it is a shared looper, it is determined by either the entry side or the exit side section, whichever has the longer strip stop time.

The moving carriage is basically designed to move due to the difference in strip tension on the inlet side and the outlet side. However, under operating conditions where fluctuations in strip tension are not stable, the moving carriage can be moved more reliably. In order to do so, an auxiliary drive mechanism may be provided on the moving carriage. An example of the auxiliary drive mechanism is shown in FIG. In this system, the pinion 32 is rotationally driven by the auxiliary drive motor 30, and the pinion 32 is meshed with the rack 33 installed on the ground to perform auxiliary drive of the moving carriage.
The movable carriage is provided with a shock absorber 31 for alleviating abrupt changes in strip tension on the inlet side and the outlet side.

[0016]

According to the present invention, the conventional entrance side looper,
Also, by sharing the exit looper, it is possible to expect significant effects such as a significant reduction in weight of machine-made works, deletion of electrical components, reduction of building space, and reduction of civil engineering costs.
