Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a steel material for displaying information on the steel material such as an attribute number and an identification number of the steel material such as a thick steel plate.

[0002]

2. Description of the Related Art Steel materials such as thick steel plates are widely used as structural members of ships, bridges, pressure vessels, steel structures, and the like.
These are selected from a wide variety of steel materials having different materials, thicknesses, lengths, and the like, and are assembled by performing processing such as cutting, drilling, and welding.

[0003] The selection of a steel material is performed by confirming the display of information about the steel material such as the attribute of the steel material and the identification number. For example, an attribute, an identification number and the like are sprayed and displayed on a surface of a steel plate by spraying a white paint, and further engraved by an engraving machine or the like. Further, in a processing plant, a label stating necessary items may be attached to a side surface or an end surface of a steel sheet so that the steel sheet can be easily identified even in a stacked state.

[0004]

However, the label attached to the side surface or the end surface of the steel plate is apt to be torn, easily peeled off by touching the object, and once dropped off, when checking the steel plate, it is difficult to remove it. The steel plates stacked on the plate must be lifted with a crane or the like and checked by spraying or engraving, or the steel plates must be stacked in the longitudinal direction so that the display part or the transcribed identification number etc. can be seen,
There is a problem that the work is troublesome. Accordingly, the present invention provides a steel display device which does not fall off even when touched.

[0005]

According to the present invention, there is provided a display device for a steel material, wherein a magnetically attached portion for magnetically attaching the steel material is connected to one end of a plate-like display portion for displaying information on the steel material such as the attribute and identification number of the steel material. The magnetically attached portion is characterized in that the magnetically attached surface is opened by a yoke made of a soft magnetic material by opening a magnetically attached surface where the magnet is magnetically attached to the steel material, and the magnetically attached surface protrudes from both end surfaces of the yoke. I do.

[0006] The display unit may include spelling means for spelling a label for displaying information on the steel material such as an attribute of the steel material and an identification number.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a steel display device of the present invention, in which (a) is a plan view, (b) is a side view and a partially enlarged view thereof, and FIG. 2 is a steel display device of the present invention. FIG. 4 is an exploded perspective view showing a state where a label is attached.

The steel display device 1 comprises a plate-like display portion 2 and a magnetically attached portion 3 at one end of which the magnetic display device 1 is magnetically bonded to a steel material.

The plate-shaped display section 2 has a hole 6 through which a binding tool 5 for binding a label 4 carrying information on a steel material such as an attribute and an identification number is formed. As the label 4, it is preferable to use a synthetic resin label having durability and weather resistance.

As the means for binding the label 4, other well-known binding means can be applied other than the combination of the binding tool 5 and the hole 6 shown in FIG. Items may be posted. The plate-shaped display unit 2 uses a metal plate or a synthetic resin plate.

[0011] One end of the display unit 2 is joined by welding, an adhesive, or the like.
Alternatively, the magnetically bonded portion 3 formed integrally is surrounded by a yoke 8 made of a soft magnetic material by opening a magnetically bonded surface 7a on which a magnet 7 having a rectangular cross section is magnetically bonded to a thick plate.

A ferrite magnet,
A ferromagnetic material such as an Nd-Fe-B magnet or a rare earth magnet is used. By surrounding the magnet 7 with the yoke 8, the magnetic adhesion to the steel plate can be increased.

FIG. 3 is a perspective view for explaining a state in which the steel display device of the present invention is restored from an inclined state.

In the present invention, it is very important that the level of the magnetized surface 7a of the magnet 7 be higher than the level of both end surfaces 8a of the yoke 8.

That is, when the level of the magnetically attached surface 7a of the magnet 7 is equal to or lower than the level of the both end surfaces 8a of the yoke 8, the magnetically attached surface of the magnet may be brought into contact with the steel display device. When inclined with respect to S, the magnetically attached surface separates from the steel sheet S and falls off. In particular, it is often found in thick steel plates having arc-shaped end faces.

However, if the level of the magnetically attached surface 7a is higher than the level of both end surfaces 8a of the yoke, even if the magnetically attached surface 7a of the magnet 7 is inclined to the position shown by the dashed line in FIG. To the original state shown by the solid line
Does not fall off the steel sheet S. The height at which the magnetized surface 7a of the magnet 7 projects from both end surfaces 8a of the yoke 8 in order to restore the inclined steel display device 1 is, for example, 3.5 mm in the depth of the yoke and 4.0 mm in the height of the magnet. In the case of, project it by 0.5 mm.

FIG. 4 is a perspective view showing a state in which the steel display device of the present invention is applied to a steel plate.

[0018] A steel material display device 1 in which a label 4 on which necessary information on the stacked steel plates S is posted is bound by a binding device 5.
Is magnetically attached to the stacked corresponding steel plates S.

For example, even if the steel display 1 that is overlapped by touching the uppermost label is tilted downward, the steel display 1 does not fall off from the end face of the steel plate S and is strongly magnetized. Restore the original state that has been. In addition, even if the upper display 1 for steel material is grasped and opened to see the label between the display 1 for steel materials, the upper display 1 for steel does not fall off and is restored to the original state when released. I do.

[0020]

According to the present invention, there is provided a display device for a steel material, in which a magnetized surface of a magnet is opened and the magnetized surface is surrounded by a yoke made of a soft magnetic material, and the magnetized surface protrudes from both end surfaces of the yoke. Because of the magnetically attached portion, the steel indicator can be magnetically attached to the steel with a strong magnetic force, and does not fall off even if the steel indicator touches the object and opens up and down.
