Abstract

(57) [Abstract] [Purpose] The barcode label 30 is easily attached to and detached from the pipe material 10 to prevent the barcode label 30 attached to the pipe material 10 from being accidentally detached from the pipe material 10. Further, the fixing plug 20 used for mounting the barcode label 30 can be reused. [Structure] A fixing plug 20 is used whose outer peripheral surface is tapered toward one end so that one end is fitted into the end of the pipe 10. Then, the barcode label 30 is wrapped around the fixed plug 20 so that the barcode printed portion 31 of the barcode label 30 is exposed from the pipe material 10, and one end of the fixed plug 20 is pushed into the end of the pipe material 10. The bar code label 30 is fixed to the pipe material 10. When the fixing plug 20 is removed from the pipe material 10, the barcode label 30 is removed from the pipe material 10 without a trace, and the removed fixing plug 20 is repeatedly used for fixing the barcode label 30 to another pipe material 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fixing a bar code label on a pipe material and a fixing plug used for the method.

[0002]

2. Description of the Related Art For a nuclear fuel clad tube that needs to be identified one by one, a bar code has been conventionally attached to each tube. As a technique for applying a bar code to a tube, a method of directly marking a bar code on the tube is disclosed in JP-A-2-6782. Further, a method of fitting an end plug having a bar code engraved into the inside of a pipe end is disclosed in Japanese Patent Publication No. 57-4916. Further, although there is no particular publication, a method of sticking a barcode label on which a barcode is printed on the tube surface is also widely used.

[0003]

However, the method of directly marking the bar code on the tube has a problem that the display remains on the tube even after the bar code is no longer needed. Further, in the method of attaching the bar code label to the pipe, the label can be removed for the time being, but it takes time to remove it, and if the label is easily peeled off, the label may be lost. In this respect, the method of fitting the end plug having the bar code engraved into the tube end portion ensures that the bar code is applied to the tube when necessary, and can be easily removed when unnecessary. However, the end plug with the bar code engraved cannot be reused for other pipe materials, which is not economical.

An object of the present invention is to attach a bar code label to a pipe material easily, to prevent the installed bar code label from being accidentally detached, and to attach a bar code label which is extremely economical. And to provide a stopper.

[0005]

A method of fixing a bar code label according to the present invention is a method of fixing a bar code label having a bar code printed on a pipe material.
After winding a bar code label on the fixed plug so that the bar code printing portion is located at the other end of the fixed plug, one end of which is fitted into the end of the pipe, the one end of the fixed plug is attached to the end of the pipe. It is characterized by being fitted into the end portion.

The bar code label fixing plug of the present invention is a fixing plug used in the above bar code label fixing method, and is made of a hard elastic material such as resin so that one end can be fitted into the end of the pipe material. The outer peripheral surface is tapered toward one end.

[0007]

According to the bar code label fixing method and the fixing plug of the present invention, the bar code label wound around the fixing plug is fixed to the pipe material by fitting one end portion of the fixing plug into the end portion of the pipe material. . In the barcode label fixed to the pipe material, the barcode printing portion is located at the other end of the fixing plug and is exposed to the outside of the pipe material, so that the barcode printing portion can be read. By tightly inserting the fixing plug for fixing the barcode label on the pipe material into the pipe end, the barcode label is prevented from being separated from the pipe material.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a fixing state of a barcode label according to the present invention, FIG. 2 is a sectional view of a pipe material to which the barcode label is fixed, FIG. 3 is a plan view of a barcode label fixed to the pipe material, and FIG. FIG. 4 is a side view of a fixing plug used for fixing a barcode label.

The fixing plug 20 is a cylindrical solid body made of a relatively hard elastic material such as synthetic resin or hard rubber.
The outer peripheral surface is a tapered surface whose diameter is gradually reduced toward one end. The fixing plug 20 has an outer diameter D1 at one end smaller than the inner diameter d of the pipe 10 and an outer diameter D at the other end so that almost half of the entire length L is fitted into the end of the pipe 10.
2 is set to be larger than the inner diameter d of the pipe material 10. The inclination angle of the outer peripheral surface of the fixing plug 20 with respect to the center line is preferably set to about 1 to 3 degrees in order to prevent the fixing plug 20 from coming off from the inside of the tube end and to facilitate the attachment / detachment.

The bar code label 30 fixed to the pipe member 10 by the fixing plug 20 has substantially the same length as the total length L of the fixing plug 20, and the width is such that the bar code label 30 can be wrapped around the entire circumference of the fixing plug 20. As described above, the length is larger than the circumferential length of the fixed plug 20 at the large-diameter end. And
The barcode is printed on a substantially half area of the barcode label 30 in the length direction. The length L2 of the bar code printing part 31 in the bar code label 30 is fixed to the end of the pipe material 10 in order to prevent the bar code printing part 31 from interfering with the end part of the pipe material 10 when reading the bar code.
The length L1 is shorter than the length L1 of the other end of the fixing plug 20 exposed from the pipe material 10 when one end of 0 is fitted.

Next, a method of fixing the bar code label according to the present invention will be described. First, the bar code printing portion 31 of the bar code label 30 is positioned on the large-diameter side end of the fixing plug 20, and the bar code label 30 is wound around the fixing cap 20. Next, the small-diameter side end of the fixing plug 20 is fitted into the end of the pipe material 10. Since the fixing plug 20 is made of a relatively hard elastic material such as synthetic resin or hard rubber, the pipe material 10
The inner peripheral edge of the pipe end is fixed by pushing it into the end of the stopper 2
The outer peripheral surface of No. 0 is bitten, and the fixing plug 20 is securely fixed to the pipe material 10. By fixing the fixing plug 20 to the pipe material 10, the barcode label 30 wound around the fixing plug 20 is fixed to the pipe material 10. The bar code label 30 fixed to the pipe member 10 has a bar code printing section 31 with a fixing plug 2
Since it is located at the other end of 0 and is exposed to the outside of the pipe material 10, the barcode can be read without any trouble.

When the bar code label 30 becomes unnecessary, the fixing plug 20 is pulled out from the pipe material 10. This allows
The bar code label 30 is easily removed from the tubing 10. There is no possibility that traces of the barcode label 30 will remain on the pipe material 10 from which the barcode label 30 has been removed. Tubing 10
Since the fixing plug 20 extracted from the device has no barcode, it is repeatedly reused for fixing the barcode label 30.

[0013]

[Table 1]

Table 1 shows a specification example of the fixing plug 20 and the bar code label 30 together with the specification of the pipe material 10. The pipe material 10 is made of a zirconium alloy, the fixing plug 20 is made of hard polyethylene, and the barcode label 30 is made of paper.

[0015]

As is apparent from the above description, according to the present invention, the bar code label is easily fixed to the pipe material by pushing the fixing plug into the pipe material. The bar code label fixed to the pipe material is reliably read because the bar code printing portion is exposed from the pipe material and is supported by the fixing plug from the back side to prevent distortion and the like. By removing the fixing plug from the tubing, the bar code label can be easily removed from the tubing without leaving any trace, and the removed fixing plug can be reused repeatedly. In particular, since the fixing plug of the present invention has a taper shape that does not easily come off from the pipe material, it can reliably prevent the bar code label fixed to the pipe material from being accidentally removed.
