Embodiments of the present invention will be described below with reference to the drawings.

<A> Non-Contact Inspection Apparatus The non-contact inspection apparatus 1 measures and inspects the length of a steel material such as a sheet pile or H-steel without contact, and for example, a truck 7 or the like. The length is measured in a non-contact manner without unloading a large number of materials 6 loaded from the carrier, and the materials 6 are received.

As shown in FIG. 1, for example, as shown in FIG. 1, a non-contact inspection device 1 has a stage 3 arranged on both sides or one side using a premises road 2 such as a factory, and a tent cover 4 of a tent ground is provided on an upper portion.
do. Inside the tent cover 4, for example, two light irradiation devices 10 are arranged so as to be movable back and forth, left and right, and up and down, and a position measuring device 30 for measuring an interval between the two light irradiation devices 10 is provided. The measured data is sent to the measurement room 5 and the length of the material 6 is calculated. The inspection data of the material 6 is input by the input device 20 and sent to the measurement room 5 together with the length of the material 6.

<B> Light Irradiation Apparatus The light irradiation apparatus 10 can irradiate a beam of visible light, and an apparatus that can irradiate in a fan shape is more convenient. For example, a laser marker (laser marking by Riken Shokai) can be used.

In order to measure the length of the material 6, it is convenient to use two or more light irradiation devices 10 as much as possible.
For example, as shown in FIG. 2, the beam of one light irradiation device 10 is irradiated on one end of a material 6 such as a steel material, and the beam of the other light irradiation device 10 is irradiated on the other end of the material 6. The position of each light irradiation device 10 is determined by the position measurement device 30, and the length of the material 6 is determined by the calculation device 40. Note that the computing device 40 may be a personal computer or a dedicated device.

<C> Position measuring device The position measuring device 30 is, for example, as shown in FIG.
The position of 0 is detected. The beam of the light irradiation device 10 is irradiated on the material 6, and the light irradiation device 10 is moved so that the light mark 11 is displayed on one end of the material 6. The moving distance is measured by position measuring means such as encoders 31 and 32, and the position of the light irradiation device 10 in the length direction of the material 6 is measured.

The light irradiation device 10 is mounted, for example, so as to rotate with respect to the measurement direction of the material 6 and to move left and right and up and down. In particular, when a balance mechanism such as the spring balancer 33 is used for the vertical mechanism, the light irradiation device 1
0 can be treated as weightless. Travel motor 34
Utilizing can make the movement of the light irradiation device 10 easier.

<D> Input Device and Output Device The input device 20 inputs inspection data such as scrap names and extra contents of the material 6 such as steel. Input device 2
For 0, a handy terminal is convenient. Input device 20
By using the optical cable 21 and the optical communication device 22, data can be transmitted at high speed. In order to eliminate the need for wiring, a wireless system may be used. For example, optical space transmission is performed between the input device 20 and the optical communication device 22, and the optical communication device 22 is connected to the computing device 40 with the cable 23. By arranging the input device 20 at a plurality of locations, the input operation can be enhanced.

When outputting at high speed, the output device 50 can use a laser printer, and can output an inspection slip for collectively displaying the length and input data of each material 6.

Hereinafter, the operation of the non-contact inspection device will be described.

<A> Measurement of Material Length Taking H steel as an example of the material 6 as shown in FIGS. 3 and 4, for each H steel, the light beam mark 11 of the light irradiation device 10
Is moved to the end of the H steel so that the position of the light irradiation device 10 is input to the calculation device 40. By inputting the positions of both ends of the H steel, the length of the H steel can be obtained.

Even if the H steel is located below the mountain, by moving the light irradiating device 10 to an appropriate position, a light beam can be made to enter from a gap between the steel materials and can be irradiated to the end of the H steel. Can be measured accurately without contact. When the stage 3 is used, the side surface can be easily measured.

<B> Input of inspection data and output of inspection slip The length and number of the H steel measured are displayed on the display screen of the input device 20, so that the inspection data such as scrap name and extra contents of the H steel are displayed. Enter

The length of each H steel measured and the acceptance data are as follows:
The data is edited in a predetermined format by the calculation device 40 and is output from the output device 50 as, for example, an inspection slip as shown in FIG.

[0020]

According to the present invention, the following effects can be obtained. <B> Even if the material is piled up on the mountain, the length of the material below can be accurately measured by using the light beam. <B> Since a light beam may be applied to a predetermined position (for example, both ends) of the material, it can be measured by one person.
