Description

[Detailed description of the invention] [Industrial application field] The present invention is designed to continuously supply hoop material in a continuous processing line such as an annealing, pressing, and plating line.
The present invention relates to a hoop material supply device that can quickly connect a trailing hoop material.

[Conventional technology]

FIG. 3 is a diagram showing an example of the configuration of a conventional hoop material supply device. In the figure, 1 is a processing line such as an annealing, pressing, and plating line, 2 is a shear/welding unit that integrates a shear 5 for cutting the hoop material, and a welding device for welding, and 3 is a shear/welding unit for cutting the hoop material. A pinch roll 4 for feeding the material to the line 1 is a material clamping device, which is composed of input side clamps 4a, 4b and line side clamps 4c, 4d. 5 is a shear for cutting the hoop material, 6 is a chute for discharging residual material attached to the line side of the shear 5 position of the shear/welding unit 2, 7 is an uncoiler for the leading hoop, and 8 is the trailing hoop. These uncoilers 7 and 8 are mutually rotated 180 degrees around the rotation shaft 11, so that
It is now possible to swap the leading and trailing rows.
9 is a free roller. With the above configuration, the hoop material wound around the preceding uncoiler 7 is pulled out from the uncoiler 7 and is drawn between the free rollers 9, between the input side clamps 4a and 4b, between the shears 5, between the line side clamps 4c and 4d, and between the pinch rolls 3. , and is continuously supplied to the processing line 1 by the driving force of the pinch rolls 3. When the leading hoop material runs out and the end of the hoop material comes before the shear 5, the line is stopped, the hoop material wound around the trailing hoop uncoiler 8 is pulled out, and the hoop material is pulled out between the free rollers 9 and the shear 5. through it and let its tip hang down to the discharge chute 6. In this state, all the clamping devices 4 are clamped, and the shear 5 simultaneously cuts the leading hoop material and the trailing hoop material while holding the hoop material. At this time, the tip remaining material of the trailing hoop material falls by the chute 6 and is automatically removed, but the remaining material of the leading hoop material is removed manually. Thereafter, the shear/welding unit 2 is shifted, the welding device is positioned at the shear cut portion of the preceding material and the succeeding material, and the preceding material and the succeeding material are welded and connected. Thereafter, all of the clamping devices 4 are opened, and the uncoiler 7 and the uncoiler 8 are rotated about the pivot shaft 11 to replace each other, and after making the trailing uncoiler 8 the leading uncoiler, the line is started, and the uncoiler 8
The hoop material is supplied to the line from

[Problem that the invention attempts to solve]

However, with such conventional equipment, the trailing hoop material cannot be set in advance on the welding equipment, which increases the line's downtime, and increases the amount of work required to manually discharge the remaining material from the leading hoop material. The line down time will also be extended. If this residual material is to be automatically discharged, a device having at least three functions of hold, shift, and up/down is required, which is complicated and expensive. The present invention aims to overcome the drawbacks of such conventional devices.

[Means for solving problems]

FIG. 1 is a diagram showing an example of the configuration of a hoop material supply device according to the present invention. In the figure, 1 is a processing line, 2 is a shear/welding unit, 3 is a pinch roll for feeding the hoop material to line 1, and 4 is a material clamp device, including input side clamps 4a, 4b and line side clamps 4c, 4d. However, according to this invention,
Lower clamp 4b among input side clamps 4a and 4b
A vacuum suction chamber is provided in the vacuum unit 10, and the trailing hoop material 8 is
can be fixed by vacuum adsorption. 5 is a shear for cutting the hoop material, 6 is a chute for discharging the remaining material attached to the line side of the shear 5 position of the shear/welding unit 2, 7 is an uncoiler for the leading hoop, and 8 is the trailing hoop. These uncoilers 7 and 8 are designed so that their leading and trailing positions can be swapped by mutually rotating 180 degrees about a pivot shaft 11 as a rotation axis. 7 is a leading hoop material, 8 is a trailing hoop material, and 9 is a free roller. FIG. 2 is a configuration diagram of the welding device when the hoop materials 7 and 8 are cut by the shear 5 and then the welding device is positioned at the cut portion and welded. In the figure, 2 is a shear/welding unit, 21 is a welding torch, 22 is a welding clamp, 2
3 is a welding back bar.

[Effect]

With the above configuration, first, while the line is operating, the trailing hoop material 8 wound around the trailing hoop uncoiler 8 is pulled out, and its tip is connected between the free rollers 9, between the input side clamps 4a and 4b, and between the shear 5. Pass it through so that it is below the preceding hoop material, guide it to the discharge chute 6, and let it hang down to the discharge chute 6. Then, when the preceding hoop material 7 is supplied to the line 1 and the remaining amount becomes small, the line is stopped, and at the same time, the input side clamps 4a, 4b and the line side clamp 4
c and 4d are clamped to fix the hoop materials 7 and 8 , and the shears 5 cut the hoop materials 7 and 8 .
After that, only the upper clamp 4a of the input side clamps 4a and 4b is opened, and the lower clamp 4b is in a state where the trailing hoop material 8 is fixed by vacuum suction,
The remaining material of the preceding hoop material 7 is removed by rewinding the preceding hoop uncoiler 8 in the reverse direction. At this time, the remaining material of the trailing hoop material 8 has already been automatically removed through the discharge chute 6 at the same time as cutting. After this, the shear/welding unit 2 is shifted to weld the cut portion of the hoop materials 7 and 8 in the state shown in Fig. 2, the hoop materials 7 and 8 are connected, the line is started, and the hoop The supply of materials will be resumed. At this time, the uncoilers 7 and 8 are rotated 180 degrees about the rotation axis 11, so that the trailing uncoiler 8 is used as a leading uncoiler and the leading uncoiler 7 is used as a trailing uncoiler.

[Effect of idea]

Trailing material can be set during line operation,
Since the remaining material of the preceding material can be automatically removed by the uncoiler, the line stop time is shortened (about 30 seconds) and there is no need for manpower or special equipment for removing the remaining material.
