Abstract

PURPOSE:To read a bar code regardless of the direction of an article. CONSTITUTION:A bar code member 10 is equipped a cylindrical tube 12. A bard code 13 is printed on the outer peripheral face of the tube 12. Also, the bar code member 10 is equipped with a slit 11. For example, at the time of loading the bar code member 10 on a hanger, the bar code member 10 is fixed by using the slit 11. The bar code 13 is printed along almost the entire periphery. The bar code 13 can be read by a bar code reader regardless of the direction of the article.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code member having a bar code.

[0002]

2. Description of the Related Art Conventional bar code members have a flat label shape. The bar code reader recognizes the information and the like of the article attached to the bar code reader by reading the brightness of the reflected light of the laser light emitted on the bar code label.

[0003]

The bar code readers currently used cannot receive the reflected light when the bar code label is tilted by a certain angle or more. This tilt angle is called a skew angle. As shown in FIG. 12, in the general barcode reader R, the skew angle is + 10 ° to
It is about −30 °. Therefore, the bar code label L cannot read the bar code because the bar code label L does not fit within the skew angle within a certain range depending on the orientation of the article (not shown).

This problem is particularly serious in the following cases. (1) When the article has a cylindrical or columnar shape such as a bottle: FIG.
As shown in FIG. 3, the barcode label L is not provided on the entire circumference of the bottle B, but only on a part of the bottle B.
Is not attached. Therefore, the barcode cannot be read at an arbitrary position, and it is necessary to regulate the position of the bottle B so that the barcode label L faces the barcode reader R from the front. The position regulation is, for example, work for aligning articles. (2) When an article hangs on a hanger or the like and rotates: As shown in FIG. 14, the barcode label L is a mail bag P.
Is attached to a part of an article such as. When the mail bag P is hung on a hanger (not shown) and the hanger rotates, the bar code reader cannot read the bar code.

[0005]

The present invention has solved the above-mentioned problems by a bar code member having a plurality of bar codes provided in the circumferential direction of a cylindrical surface having an outer peripheral surface as a curved surface.

[0006]

Since the bar code is marked in the circumferential direction of the cylindrical surface, when the bar code reader faces the bar code member, the bar code is always positioned within the skew angle range of the bar code reader. Also, when the goods move,
For example, if the article is conveyed on a conveyor, the bar code member will always pass within the skew angle of the bar code reader. The same applies when an article is hung on a hanger and rotationally moved. That is, as long as the article has a posture in which the scanning line of the barcode reader and the barcode intersect at a substantially right angle, the barcode reader always reads the barcode regardless of the orientation of the article. Information can be obtained.

[0007]

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

FIG. 1 shows a first embodiment of a bar code member 10 according to the present invention. The barcode member member of the present embodiment is a cylindrical tube 12 having a slit 11 in the axial direction. The barcode 13 is printed on the outer peripheral surface of the tube 12. The bar code 13 is marked almost all around. Margins 14 and 1 on the outer peripheral surface at the top and bottom
There is 5.

2 and 3 show an example of using the bar code member 10. FIG. 2 shows an example of attachment to the hanger 16, which is pushed into the root of the hook 17 using the slit 11. FIG. 3 shows an example of being attached to the mail bag 18,
The bar code member 10 is passed through the cord 19 using the slit 11.

FIG. 4 shows an example of reading the bar code member shown in FIG. R is a fixed bar code reader. Figure 2
Also, as shown in FIG. 3, the bar code member 10 attached to the article (not shown) is moving in the arrow direction together with the article. During the movement, the barcode on the barcode member 10 always passes through the scanning line of the barcode reader R within the range of the skew angle regardless of the orientation of the article. The shaded area is the reading range of the barcode reader R.

Even when the slit 11 faces the bar code reader, the bar code can be read as long as the bar code exists within the range of the skew angle. 5 and 6 show the case where the bar code member 10 having the slit 11 crosses the scanning line S of the bar code reader. The arrow indicates the moving direction of the article. The trajectory of the scan line zigzag across the barcode of the barcode member 10 that moves with the article. Even if there is a slit 11 in a part, it is possible to read in the other part.
Unless the width of 1 is extremely large, it does not hinder reading.

FIG. 7 shows a second embodiment of the bar code member 20 according to the present invention. Bar code member 2 of this embodiment
0 is a cylindrical tube 22. The barcode 23 is printed on the outer peripheral surface of the tube 22. Margins 24 and 25 are provided on the outer peripheral surfaces of the upper and lower ends. The bar code member 20 of this embodiment is used by being inserted into a string or the like.

FIG. 8 shows a third embodiment of the bar code member 30 according to the present invention. Bar code member 3 of this embodiment
0 is a cylindrical member 32 having a groove 31. The barcode 33 is printed on the outer peripheral surface of the cylindrical member 32. Margins 34 and 35 are provided on the outer peripheral surfaces of the upper and lower ends. The bar code member 30 of this embodiment is suitable for being used by being snap-fitted to a hanger.

FIG. 9 shows a bar code member 40 according to a fourth embodiment of the present invention. Bar code member 4 of this embodiment
0 is the flexible sheet 42. The flexible sheet 42 is used by being rolled into a cylindrical shape. The barcode 43 is printed on the outer peripheral surface of the flexible sheet 42. Margins 44 and 45 are provided on the outer peripheral surfaces of the upper and lower ends. The bar code member 40 of the present embodiment is used by being inserted into a string or the like, as in the second embodiment.

FIG. 10 shows a bar code member 50 according to the present invention.
5 shows a fifth embodiment of the present invention. The member 50 of this embodiment is a flexible sheet 52. The flexible sheet 52 has a protrusion 51 at one end and a notch 51 ′ at the other end. A cylindrical surface is provided by inserting the protrusion 51 into the notch 51 '. The barcode 53 is printed on the surface of the flexible sheet 52.

FIG. 11 shows a bar code member 60 according to the present invention.
The 6th Example of is shown. The barcode member of this embodiment is the flexible sheet 62. The flexible sheet 62 has a notch 61 connected to the lower side at one end and a notch 61 ′ connected to the upper side at the other end. Notch 61,6
The engagement of the 1's provides a cylindrical surface. The barcode 63 is printed on the surface of the flexible sheet 62.

In the above embodiment, the cylindrical shape is exemplified, but the outer peripheral surface may be a curved surface and may have an elliptical cross section.

[0018]

Since the present invention has the above-described structure, the bar code reader can read the bar code regardless of the orientation of the article. Especially when articles are conveyed on a conveyor or when they are hung on a hanger and conveyed, the bar code always crosses the scanning line of the bar code reader. No need for alignment work.
