Abstract

PURPOSE:To enable a safe and sure visual inspection of both sides of a strip by a worker and to facilitate reduction in working time and scrap process. CONSTITUTION:A coiled strip 52 is unwound by a pay-off reel 40, the leading end is put through a shear 30 and a roller table 20, sent under a deflector roll 2, abutted on a guide plate 3 and advanced upward curvedly. The strip 52 is pressed to the deflector roll 2 to be wound on the deflector roll by rotating a snapper roll 4, the leading end of the strip is inserted, by rotating the snapper roll and the deflector roll, into the grip groove 11a of a reel 11 to be gripped, and a visual inspection is performed on the upper surface B of the strip between the reel and the deflector roll. The strip is rewound, and simultaneously wound on a tension reel 10 and a visual inspection is performed on the reverse surface A on the roller table.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface inspection equipment for a metal strip wound into a coil.

[0002]

2. Description of the Related Art FIG. 3 is a side view showing the concept of an example of a conventional strip material inspection facility. As shown in FIG. 3, in the conventional surface inspection equipment for coiled metal strip material, the strip material 52 is rewound from the coil 51 by the pay-off reel 40 and moved onto the table 70 by the belt conveyor 60. Visual inspection is performed from the back surface of the strip 52 at the back surface inspection position A above the belt conveyor 60, and the rotating coil 50 at the machine side surface inspection position B of the payoff reel 40.
Is visually inspected from the side surface of the strip, that is, the surface of the strip 52.

If there is a scratch on the strip 52, the shear 30
The part is cut by and scrapped and discarded.

[0004]

By the way, in the conventional device as described above, there is a limit to the length for inspecting the strip 52.

If the defective portion of the strip 52 is long, it is difficult to process the defective portion, so that there is a problem that it requires a long working time.

Furthermore, since the worker must be placed at the surface inspection position B where the coil 51 on the machine side of the payoff reel 40 rotates, it is dangerous and there is a problem that the safety is lowered.

The present invention has been proposed in order to solve each of the above-mentioned problems, and it is possible to inspect both sides of a strip at the same time, easily dispose of the strip scrap, and have a high safety. The purpose is to provide inspection equipment.

[0008]

[Means for Solving the Problems] As a structure for achieving the above-mentioned object, in a strip material inspection equipment of the present invention, after winding the strip material into a coil shape, the strip material is rewound to remove the front and back surfaces thereof. In a facility for visual inspection, a payoff reel for mounting and rewinding a coil that winds a strip, a conveyor arranged on the exit side of this payoff reel, and a length direction of the strip on the exit side of this conveyor. To the deflector roll, an arc-shaped guide plate for winding the strip on the exit side of the deflector roll from below the deflector roll, and a strip wound around the deflector roll from below by the guide plate. A snubber roll that is pressed from above to advance in the horizontal direction and a gripper that grips the end of the strip are provided on the reel so that the strip width of the strip is increased in the strip width direction at the entrance side of the deflector roll. Tension reel, a scrap coil transfer device that moves in parallel with the conveyor between the tension reel and the conveyor, and a cutting machine interposed between the payoff reel and the conveyor or between the conveyor and the deflector roll. It is characterized by having and.

[0009]

In the strip material inspection equipment of the present invention configured as described above, when the strip material coil is mounted on the pay-off reel and rewound, and the leading end portion is fed below the deflector roll by the conveyor, the strip material The tip portion contacts the guide plate and advances while curving upward.

Then, the strip material is pressed from above by the snubber roll toward the deflector roll, and when the snubber roll is rotated, the strip material is wound around the deflector roll, and further,
The snubber roll and the deflector roll are rotated to horizontally advance the strip material and feed it to the tension reel, and the tip end thereof is gripped by the gripper of the reel.

Next, while rotating the snubber roll and the deflector roll and moving the deflector roll to the exit side (anti-tension reel side) while rewinding the strip material by the pay-off reel, the strip between the deflector roll and the tension reel. An inspection position for one surface is formed on the upper surface of the material.

In this state, the strip material is rewound by the pay-off reel and wound by the tension reel, and the strip material is inspected from both sides at an arbitrary length at the inspection position on the one surface and the inspection position on the other surface on the conveyor. inspect.

If the strip material has a defective portion, it is cut by a shear and wound by a tension reel, and the tension reel is retracted to move the wound scrap coil to above the scrap coil transport path to scrap it. The scrap reel is supported by a coil carrier, the tension reel is further retracted to remove the reel from the scrap coil, and the scrap coil is carried by the scrap coil carrier.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a strip material inspection equipment which is an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG.

In FIGS. 1 and 2, reference numeral 1 is a dolly,
A deflector roll 2 is rotatably mounted on the trolley, and a snubber roll 4 and a guide plate 3 provided with a motor (not shown) for rotating the snubber roll 4 at its tip end are rotated by a hydraulic cylinder 6 and a lever 5. The carriage 1 is rotatably mounted so that the carriage 1 is moved by the hydraulic cylinder 7 on the rail 9 in the longitudinal direction of the strip 52.

A tension reel 10 is provided with a reel 11 provided with a grip groove 11a, which is axially mounted on the guide rail 14 by a hydraulic cylinder 13 shown in FIG. It is configured to move in the plate width direction of the material 52.
