DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for checking individual rolls when changing a ground roll transported from a roll shop to a mill.

[0002]

2. Description of the Related Art When changing the rolls of a milled roll transported from a roll shop to a mill, when the rolls of the mill are changed using a roll changing cart before the mill, for example, a work roll and a multi-stage mill are used. Separate intermediate rolls, and
Each of them must be rearranged so as not to mistake the stand, the top and bottom, the drive side and the work side. For example, 5
In the stand tandem mill, there are 20 work rolls and intermediate rolls alone, and there are 40 fixed positions including the drive side and the work side. It is extremely important to incorporate the correct positions by confirming the positions.

[0003] The incorporation of rolls having different predetermined roll diameters causes a failure of the rolling device, and when the surface roughness or the finished state is different, not only the difference in the surface roughness of the sheet but also from the expected one, Causes a rolling abnormality due to the difference in the coefficient of friction of the steel sheet, leading to a sheet break. Furthermore, an error in the position of the drive side and the work side hinders the control of the plate shape, leading to a plate shape defect or a plate breakage, which leads to a rolling accident, or extremely large because rolling at a predetermined quality cannot be performed. This is a problem, and this role-specific perception is extremely important.

Conventionally, this roll has been confirmed by directly engraving characters on the end face of the roll, and performing roll tracking by a computer. Signs, letters, and numbers written on the end face of the roll set on the cart were directly viewed by a person.

[0005] This conventional recognition of each roll by direct viewing of humans requires not only manual labor but also the improvement of the identification symbol, but the flaws are found in the drive walker, the roll grinder face plate, and the guides during transportation. And recognition may be difficult.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a means for efficiently performing roll recognition at the time of changing a ground roll transferred from a roll shop to a mill without manual operation. It is in.

[0007]

According to the present invention, there is provided a roll actuality checking apparatus for assembling rolls transported from a roll shop into a mill.
Before embedding, a means for confirming the roll-specific recognition display displayed on the roll end face or end portion, a means for comparing with the roll-specific recognition display previously input to the program, and an alarm signal corresponding to the comparison are generated. Means for emitting light.

As the roll-specific recognition transmitting means provided on the roll end face, a method of providing different transmitting signals for each roll, a method of character recognition using a roll-specific recognition display symbol provided on the roll end face, or the like can be adopted. .

In addition, an electric receiving device, a character recognizing device such as a TV camera, or the like is used in combination as a receiving device in accordance with the roll-based recognition transmitting device.

Further, the alarm signal is not limited to simply issuing a caution signal to the operator, but can be a signal transmitted to the automatic recombining apparatus.

[0011]

According to the present invention, it is possible to confirm individual rolls without requiring any manual operation, and it is possible to achieve automatic conveyance of a grinding roll between a roll shop and a mill.

[0012]

FIG. 1 shows an example of the arrangement of an actual item checking device in a roll changing equipment according to the present invention.

In FIG. 1, an actual item checking apparatus 1 according to the present invention is provided on a track d for a roll transporting vehicle c which moves from a roll shop to a position of a roll changing vehicle b beside a rolling mill a. ing.

FIG. 2 shows an actual item checking device 1 of the present invention.
An example of a method of reading a roll display provided on a roll end face by a TV camera will be described.

In FIG. 2, reference numeral 2 denotes a TV camera for displaying a display symbol of the roll end face. An image from the camera showing the display of the end face of the roll R is subjected to signal conversion processing by an image processing device 3 to obtain roll tracking information. Is compared with the signal from the computer 4 to which the input signal is inputted, and an alarm signal is issued in the case of a different kind of signal.

FIG. 3 shows an example of displaying a roll-specific symbol on the roll end face in the method of reading by the TV camera. As shown in FIG. 3 (b), a concave portion 6 is formed on the roll end face. In this type, a display plate or a bar code plate 7 as shown in FIG. 3A is embedded, and the characters on the roll end face do not have flaws. Since a dial with a surface roughness and a color tone can be used, the reading accuracy of characters is improved.

FIG. 3 (b) shows the actual item checking device 1 described above.
By providing a transmitter for transmitting a signal for each roll in the end face concave portion 6 of the roll R, providing a receiving device in place of the TV camera, and performing a signal recognition process in place of the image processing device, a more accurate Roll in-kind recognition can be performed.

[0018]

According to the present invention, the following effects can be obtained.

(1) It is possible to automatically and unmannedly perform the actual operation of checking the actual roll-in roll of a mill, which was conventionally performed by a person.
The automation of the automatic transfer system for the grinding roll can be further advanced.

(2) Even in a normal roll shop in which rolls are manually conveyed, confirmation of each roll can be performed more accurately before the rolls are incorporated into the mill, and a final check mistake by a human can be prevented.

(3) Particularly, in an automatic roll shop, the actual roll can be checked before the roll conveyed by the computer is assembled into the rolling mill, so that the erroneous roll installation can be prevented.
