Abstract

Adhesive matter remaining at the end of a cuboid metal material is reliably removed in a relatively short time while suppressing the decrease in yield rate of the metal material. Distances of the upper surface and the lower surface of a cuboid metal material from a reference position are measured using a distance measurement device in the longitudinal direction of the slab including the longitudinal end of the slab. On the basis of the measurement results, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the slab is comprehended. On the basis of the state of remaining of adhesive matter, the amount and position of cutting by a cutting tool is determined. Corner removing cutting is performed on the upper and lower surfaces of the longitudinal end of the slab using the cutting tool in accordance with the determined amount and position of cutting.

First claim

1 .- 6 . (canceled)

7 . An adhesive matter cutting and removing method of removing adhesive matter remaining on upper and lower surfaces of a longitudinal end of a cuboid metal material by corner removing cutting, comprising:
measuring distances of the upper surface and the lower surface of the cuboid metal material from a reference position using a distance measurement device in the longitudinal direction of the cuboid metal material including the longitudinal end of the cuboid metal material; comprehending on the basis of measurement results a state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material; determining on the basis of the state of remaining of adhesive matter an amount and position of cutting by a cutting tool; and performing corner removing cutting on the upper and lower surfaces of the longitudinal end of the cuboid metal material using the cutting tool in accordance with the determined amount and position of cutting.

8 . The method according to claim 7 , wherein comprehending the state of remaining of the adhesive matter is performed by:
determining a reference line of the upper surface and the lower surface of the cuboid metal material on the basis of distribution of distance of the upper surface and the lower surface of the cuboid metal material from the reference position measured over a predetermined length or more in the longitudinal direction of the cuboid metal material, determining a corner position of the cuboid metal material from the reference line and the distribution of distance, determining a position at which the distance is smaller than the distance from the reference line by a predetermined value or more to be a place where adhesive matter remains, and determining the amount and the position of cutting by the cutting tool on the basis of the distance of the place where adhesive matter remains from the end of the cuboid metal material and the corner position.

9 . The method according to claim 7 , wherein the cuboid metal material is divided in a width direction into a plurality of sections,
for each of the plurality of sections, distances of the upper surface and the lower surface thereof including the end thereof from a reference position are measured using a distance measurement device in the longitudinal direction thereof, on the basis of the measurement results, for each of the plurality of sections, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material is comprehended, and on the basis of the state of remaining of adhesive matter of each of the plurality of sections, the amount and position of cutting by a cutting tool of each of the plurality of sections are determined.

10 . An adhesive matter cutting and removing apparatus of removing adhesive matter remaining on upper and lower surfaces of a longitudinal end of a cuboid metal material by corner removing cutting, comprising:
a cutting tool that performs corner removing cutting on the upper and lower surfaces of the longitudinal end of the cuboid metal material; a distance measurement device that measures distances of the upper surface and the lower surface of the cuboid metal material from a reference position; and a controller that causes the distance measurement device to measure distances of the upper surface and the lower surface of the cuboid metal material from a reference position in the longitudinal direction of the cuboid metal material including the longitudinal end of the cuboid metal material, comprehends on the basis of the measurement results a state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material, determines on the basis of the state of remaining of adhesive matter the amount and position of cutting by a cutting tool, and causes the cutting tool to perform corner removing cutting on the upper and lower surfaces of the longitudinal end of the cuboid metal material in accordance with the determined amount and position of cutting.

11 . The apparatus according to claim 10 , wherein the controller comprehends the state of remaining of the adhesive matter by determining a reference line of the upper surface and the lower surface of the cuboid metal material on the basis of distribution of distance of the upper surface and the lower surface of the cuboid metal material from the reference position measured over a predetermined length or more in the longitudinal direction of the cuboid metal material, then determining a corner position of the cuboid metal material from this reference line and the distribution of distance, and determining a position at which the distance is smaller than the distance from the reference line by a predetermined value or more to be a place where adhesive matter remains, and
determines the amount and position of cutting by the cutting tool on the basis of the distance of the place where adhesive matter remains from the end of the cuboid metal material and the corner position.

12 . The apparatus according to claim 10 , wherein the controller divides the cuboid metal material in a width direction into a plurality of sections,
causes the distance measurement device to measure, for each of the plurality of sections, distances of the upper surface and the lower surface thereof from a reference position in the longitudinal direction thereof including the end thereof, comprehends, on the basis of the measurement results, for each of the plurality of sections, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material, and determines, on the basis of the state of remaining of adhesive matter of each of the plurality of sections, the amount and position of cutting by a cutting tool of each of the plurality of sections.

13 . The method according to claim 8 , wherein the cuboid metal material is divided in a width direction into a plurality of sections,
for each of the plurality of sections, distances of the upper surface and the lower surface thereof including the end thereof from a reference position are measured using a distance measurement device in the longitudinal direction thereof, on the basis of the measurement results, for each of the plurality of sections, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material is comprehended, and on the basis of the state of remaining of adhesive matter of each of the plurality of sections, the amount and position of cutting by a cutting tool of each of the plurality of sections are determined.

14 . The apparatus according to claim 11 , wherein the controller divides the cuboid metal material in a width direction into a plurality of sections,
causes the distance measurement device to measure, for each of the plurality of sections, distances of the upper surface and the lower surface thereof from a reference position in the longitudinal direction thereof including the end thereof, comprehends, on the basis of the measurement results, for each of the plurality of sections, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the cuboid metal material, and determines, on the basis of the state of remaining of adhesive matter of each of the plurality of sections, the amount and position of cutting by a cutting tool of each of the plurality of sections.
