Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a measuring device for a strip material, and more specifically,
For example, the present invention relates to a measuring device for obtaining quality information of strip materials in a continuous processing line for strip materials such as thin steel sheets manufactured in a steel mill.

[Prior Art 1] Conventionally, in a continuous processing line for thin steel sheets, for example, an annealing surface treatment line, various measuring instruments are used in order to determine the processing results in each zone in the processing line.

That is, many measuring instruments are used to detect flaws on the surface of steel sheets and to obtain quality information such as the thickness of coating agents.

A total of 7 measurements were taken using these measuring devices on continuously conveyed steel plates! 1++ instruments are measured either contact or non-contact, but the majority of them are non-contact. Some quality information requires continuous measurement of the steel plate surface, while others require intermittent sampling.

In conventional measurement, the measurement equipment is fixed and each quality of the steel plate being transported is measured, so the measurement means are limited, measurement is difficult, and necessary quality information cannot be measured. there were.

In addition, there are examples in which a measuring device is incorporated into the conveyor roll of the steel plate and the temperature, plate thickness, etc. of the steel plate are determined 1 lill through the roll, but since the measurement is carried out through the shell of the roll, There were many errors in the measured values, or it was necessary to calibrate the measured values, and measurements were also limited to temperature, plate thickness, etc., and the measuring devices were equipped with only a single function.

[Problem to be Solved by the Invention 1] The present invention solves the above-mentioned problems, and simultaneously and intermittently collects a plurality of pieces of quality information on a continuously processed strip material to be measured.
It is an object of the present invention to provide a measuring device for measuring a strip material that can be accurately measured.

[Means for Solving the Problems] The present invention solves two problems, and employs the following technical means. In order to wind the strip material to be measured on the surface, open one or more measurement windows in the shell of the roll that rotates as the strip material to be measured runs, and insert the measurement window inside the 11 window. Wave Meter-j1 This is a measuring device for strip material, characterized in that it is equipped with a measuring device for obtaining quality information on strip material.

Note that the quality information measuring instruments include a surface roughness meter, a surface heat needle, a surface gloss meter, a hue needle, a sharpness meter, and the like.

[Operation 1] While the strip material to be measured is wound around the roll, the relative speed between the strip material to be measured and the roll is zero and is considered to be in a stationary state.

According to the present invention, quality information of a strip material can be obtained by using periods of quiescent relative speed between the measuring device and the strip material to be measured, which occur intermittently due to the rotation of the roll. In addition, one or more 7!111 windows in total are opened in the shell of the roll,
Since the roll is equipped with one or more measuring instruments, one or more accurate quality information can be obtained at the same time.

[Embodiment] FIG. 1 is a perspective view of a measuring device showing an embodiment of the present invention. 1 is a roll body, 2 is a shaft, and 3 is a flange to which the shaft 2 is attached on both sides of the roll body 1. 4 is total -1
One window is provided on the outer periphery of the roll body 1, and one or more locations are provided.

Reference numeral 5 denotes a measuring device, which is installed inside the roll main body 1 by means of a mounting seat 6 inside the measurement window 4, and is mounted toward the outer periphery of the roll main body 1. 7 jl in total by trolley! II machine 2a
This is for the power supply and signal electric circuit for 5. 8 is a trolley shoe current collection box, which is connected to the trolley 7 by a shoe. A rotary joint 9 supplies power to the air source and hydraulic power source necessary for the measuring device 5.

FIGS. 2 and 3 show how the roll body 1 is installed when measuring the quality of the back and front surfaces of a steel plate in a continuous processing line.

10 is a roll, 11 is a steel plate, and L is the length of the steel plate 11 wound around the outer periphery of the roll body 1. Measuring equipment 5
is installed in the roll body 1, and as shown in FIGS. 2 and 3, when the roll body I is incorporated into the line and the steel plate 11 is conveyed, the roll body I is moved so that the steel plate 11 is lengthened by the action of the front and rear rolls 10. It rotates with L wrapped around it. Then, the measurement window 4 provided on the roll body 1 rotates while the steel plate 11 and the measurement window 4 are relatively stationary during the angle corresponding to the length of the wrapped steel plate 11 due to the rotation of the roll body 1. do. During a period corresponding to this length measurement, the measuring device 5 attached to the measuring window 4 can measure the steel plate 11 in a stationary state. Moreover, the steel plate 11 is pressed against the outer periphery of the roll body 1 by the tension of the line. Therefore,
The measuring device 5 can measure the steel ill without contacting it.

In addition, as shown in FIG. 1, the power source, air source, or hydraulic source for operating the measuring device 5, the 7y11 constant result, and the control signal are provided by the trolley 7, the trolley shoe current collection box 8,
It can be supplied or taken out via the rotary joint 9, allowing connection to a host computer or an external control panel.

In this way, the quality information of each of the continuously processed thin steel plates can be measured intermittently, but without contact with the steel plate II and in a stationary state.

In the case of a steel plate, the measuring instruments 5 include a surface roughness meter, a surface heat needle, a surface gloss meter, a hue needle, a sharpness meter, and the like.

In the roll main body 1, it is possible to incorporate I or a plurality of types of measuring devices 5 among the above-mentioned measuring devices.

Also, although not shown, it would be very convenient from an operational point of view if the roll body I, together with its bearings, could be installed on a trolley and moved in and out of the line using the trolley, and the francines 3 and shafts 2 on both sides could be removed. A measuring device is constructed. Furthermore, devices other than those shown in the drawings, such as slip rings and guided radios, can be used to connect the power source to the measuring device 5, the signal line, etc. inside the rotating roll body 1 and the outside. Furthermore, it is also possible to shield the cooling inside the roll, the barge, and the measurement window with glass or the like.

Although the example of steel plates has been mainly explained above, it goes without saying that the present invention can also be applied to other strip products other than steel plates, such as paper and copper.

[Effects of the Invention] The present invention accurately measures multiple pieces of quality information of the strip material after each process in the line using a measuring device, feeds it back to line operation control in real time, and maintains a predetermined quality. It becomes easy to determine whether or not the product is being used, and to obtain data and information for quality control, which has an excellent effect on improving productivity.
