FIG. 3 is a front view showing a schematic structure of the label sticking apparatus used in the present embodiment, and FIG. 4 is a plan view showing a schematic structure of the label sticking apparatus.

As shown in FIG. 3 or 4, the label sticking device 30 of the present embodiment is for sticking the scale label 10 to each glass tube 1, and is a delivery mechanism 3 for the glass tube 1.
1, a transport mechanism 32 for the scale label 10, and a winding mechanism 33.
Is roughly divided into

The delivery mechanism 31 of the glass tube 1 drops the glass tubes 1 from the glass tube storage box 31a into the transport path 31b one by one, and the value is detected by the optical sensor 31c at the boundary 2a of the medicine 2 of the glass tube 1 to the value detected by the optical sensor 31c. Accordingly, the pushing member 31d slides the glass tube 1 so that the glass tube 1 is fed to the winding mechanism 33 while aligning the glass tube 1 at the target fixed position of the reference line 12a of the scale label 10. .

In the transport mechanism 32 of the scale label 10, the peeling portion 32a peels the scale label 10 one by one from the scale sheet 20 wound in a roll, and the transport portion 32b holds the scale label 10 by air suction. Meanwhile, it is configured to be transported to the winding mechanism 33.

The wrapping mechanism 33 contacts the scale label 10 sent from the transport mechanism 32 of the scale label 10 while the pressing roller 33a is rotating, while the glass tube 1 sent from the sending mechanism 31 of the glass tube 1 is in contact. On the other hand, while being held by the pair of guide rollers 33b, the scale label 10 is pressed against the pressing roller 33a while sandwiching it.

Hereinafter, a preferred embodiment of the method of applying a scale label according to the present invention will be described in detail with reference to the drawings, taking the case of using a label sticking device as an example.

FIGS. 5 (a) and 5 (b) are views for explaining the method of sticking the scale label according to the present embodiment. Figure 6
It is a front view which shows schematic structure of the detection tube of this Embodiment.

As shown in FIG. 5A, the scale label 10
With the edge on the side of the display unit 12 as the tip, the pressing roller 33
It is fed toward the glass tube 1 rotating between a and the guide roller 33b, and the tip edge thereof is sandwiched between the pressing roller 33a and the glass tube 1.

In this case, since the position of the glass tube 1 in the longitudinal direction is adjusted, the reference line 12a of the scale label 10 is adjusted.
Comes on the boundary 2a of the medicine 2.

Then, by rotating the glass tube 1 almost once, the display portion 12 of the scale label 10 is attached while being wrapped around the surface of the glass tube 1, and further the glass tube 1 is rotated once more. The margin portion 13 of the scale label 10 is wrapped around the display portion 12 and attached.

Further, the peeling prevention portion 14 of the scale label 10
After wrapping around the scale label 10, the guide roller 3
Lower 3b.

As a result, as shown in FIG. 5B or FIG. 6, in the detection tube 40 in which the scale label 10 is attached to the glass tube 1, the display portion 12 of the scale label 10 has the scale label 1 attached thereto.
0 of the scale label 10 while being covered by the blank portion 13 of itself, crosses the generatrix of the side surface of the detection tube 40, that is, each of the peaks and valleys forming the elements of the peeling prevention portion 14. It is attached in a state where the side intersects with the bus bar on the side surface of the detection tube 40.

As described above, according to this embodiment,
Since the graduation label 10 on which the display part 12 such as the scale and the name of the object to be measured is provided with the margin part 13 and the margin part 13 covers the display part 12 of itself, the display part 12 is rubbed. Since the edge portion of the blank portion 13 is formed in a sawtooth shape as the peeling prevention portion 14, even if there is some unevenness on the surface of the glass tube 1, each of the peeling prevention portion 14 can be prevented. Since the sides are in close contact with each other along such a surface, it is possible to prevent the scale label 10 from being peeled off from the edge.

As a result, even if the scale label 10 is attached to the glass tube 1 and the surface is rubbed, the display portion such as the scale is not erased, and the label having the display portion 12 is peeled off. It is possible to obtain a detector tube 40 which is not present.

Further, according to the present embodiment, since the scale label 10 is additionally wrapped around the glass tube 1 by adding the margin portion 13 for smoothing only the display portion 12, some impact load is generated in the detection tube 40. Even if the glass tube 1 is broken due to this, there is an advantage that the glass fragments and the chemicals 2 do not scatter.

Further, according to the present embodiment, the peeling prevention portion 14 is formed at the end portion of the scale label 10 so that the scale label 10 can be wound around the glass tube 1 multiple times. The surface roughness of the glass tube 1 is mitigated by interposing the scale label 10, and each side of the peeling prevention portion 14 adheres to such a surface, so that there is an advantage that the surface finish of the glass tube 1 may be rough. .

Furthermore, according to the present embodiment, since the display portion 12 printed on the scale label 10 is covered with the blank portion 13, the display portion 12 is not exposed, so that the glass tube 1 is directly printed. The method is not limited to such a method as screen printing, and any method can be used as long as it can print on a label.

The present invention is not limited to the above-described embodiment, but various modifications can be made. For example,
In the above-described embodiment, the peeling prevention portion 14 of the scale label 10 has a sawtooth shape in which peaks and valleys are continuous, but in the case of the present invention, the peeling arming portion 14 forms a bus bar on the side surface of the glass tube 1. Any shape may be used as long as elements including intersecting straight lines or curved lines are continuous.

7 (a) and 7 (b) are enlarged views showing another shape of the peeling prevention portion of the scale label of the present invention, the shape of the peeling prevention portion 14 is shown in FIG. ), The shape may be continuous with pentagons as elements,
As shown in FIG. 7 (b), a continuous shape may be used in which a point of a curved line is used as an element.

Further, in the above-described embodiment, the portion printed on the scale label 10 is covered with the blank portion 13 of itself, but in the case of the present invention, it is provided on the back surface side (adhesive side) of the scale label 10. If the display portion 12 such as the scale is reversely printed, the display portion 12 is not exposed when the scale label 10 is wound around the glass tube 1, so that it is not necessary to additionally secure the blank portion 13.

[0063]

As described above, according to the present invention, even if the surface is rubbed, the display portion such as the scale does not disappear, and the label printed on the display portion does not come off. Can be obtained.
