2. Description of the Related Art In the case of a label for full-circle winding in which a label is attached to the entire peripheral surface of a container, the front edge of the label is adhered to the peripheral surface of the container, and then the container is forcibly rotated to rotate around the container. Finally, the back surface of the rear edge of the label is superimposed on and adhered to the surface of the front edge of the label. In such a label for full-circle winding, an adhesive layer made of various adhesives is continuously formed on the front edge and the rear edge of the back surface of the label in the label transverse direction (the direction orthogonal to the label longitudinal direction).

[0003]

The section of the label, on which the adhesive layer is not formed, over substantially the entire length is wound around the peripheral surface of the container without the support member. For this reason, the rear portion of the label is lowered, and the rear end and the start end of the label are not aligned on the same line, causing a vertical displacement, or the label is easily loosened and the label sticking accuracy is low. Means for maintaining the attitude of the label may be to increase the thickness of the label to increase the rigidity of the label, or to form an adhesive layer on the entire back surface of the label. Poor. Also, in the method of applying the adhesive immediately before cutting the drawn-out roll label, there is a problem that the adhesive is easily attached to the cutting device and the cutting becomes impossible. At present, there is a long-awaited desire to attach a label for all-around winding at a high speed.

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

<A> Labeling Machine FIG. 2 is a plan view of a known labeling machine. The present invention is characterized in that a roll label 1 described later is used. Referring to the illustrated labeling machine, a tape 2 drawn from a roll label 1 is wound around a plurality of tension rollers 3 for keeping the tension of the tape 2 constant, and further, a drawing device 4 composed of a pair of rollers.
, So that the tape 2 can be continuously supplied to a cutting device 5 that cuts the tape 2 at a predetermined size.

In the vicinity of the cutting device 5, a transfer drum 6 of a negative pressure suction type is rotatably disposed. The transfer drum 6 is a drum for sucking the back surface side of the label 7 manufactured by cutting the tape 3 to the peripheral surface and transferring the label 7 to the sticking drum 8.
The negative pressure on the peripheral surface is cut off when it comes closest to the sticking drum 8. The transfer drum 6 may be omitted in some cases.

The sticking drum 8 is constituted by a drum capable of sucking and transferring the surface side of the label 7 over a section from a label receiving point of the transfer drum 6 to a label sticking point to the container 9. In the vicinity of the sticking drum 8, a heating device 10 capable of heating the rear surface of the label is provided. Heating device 1
No. 0 is capable of blowing hot air at a predetermined temperature toward the peripheral surface of the sticking drum 8.

The container 9 can be transported in the tangential direction of the sticking drum 8 by a transport device 11 indicated by an arrow. Also, the container 9 can be forcibly rotated at the time of label attachment. As means for giving rotation to the container 9, for example, the upper and lower portions of the container 9 shown in FIG.
And lower chuck 13 forcibly rotating at the time of label attachment.
Means can be adopted.

The present invention is not limited to the labeling machine described above, but may be any machine provided with at least a label cutting means and a label backside heating means.

<B> Roll Label The roll label 1 is made of, for example, a non-heat-shrinkable or heat-shrinkable film or paper as shown in FIG. 1, and is continuous at least along the longitudinal direction of the back surface 14 of the tape 2. The heat-sensitive adhesive band 15 is formed in advance.

The reason why the heat-sensitive adhesive band 15 is formed continuously along the longitudinal direction of the tape 2 is to maintain the attitude of the label 7. That is, the heat-sensitive adhesive band 15 functions to maintain the adhesive relationship with the peripheral surface of the container 9 and to increase the overall rigidity of the label 7 due to the rigidity of the heat-sensitive adhesive band 15. In FIG. 1, the heat-sensitive adhesive strip 1 is narrowly attached to the upper and lower edges of the tape 2.
5 and 15 and a form in which the heat-sensitive adhesive portions 16 are formed in the transverse direction of the tape 2 at intervals equal to the label pitch P and straddling the expected label cutting position. The heat-sensitive adhesive portion 16 is formed intermittently as shown.

The heat-sensitive adhesive band 15 and the heat-sensitive adhesive portion 16 are made of a heat-sensitive adhesive material in which an adhesive is sealed in a known fusible capsule that does not exhibit adhesiveness at room temperature and is not heated, and exhibits adhesiveness at heat. A known transfer method can be employed.

[0015]

Next, a method for attaching a label will be described.

<A> Tape Extraction Step As shown in FIG. 2, the tape 2 is continuously extracted from the roll label 1 by the operation of the extraction device. This tape 2
As described above, the heat-sensitive adhesive band 15 and the heat-sensitive adhesive portion 16 are formed on the back surface 14.

<B> Cutting Step Next, the center of the heat-sensitive adhesive portion 16 of the tape 2 is cut by the cutting device 5 to produce a predetermined label 7 shown in FIG. Since the heat-sensitive adhesive band 15 and the heat-sensitive adhesive portion 16 on the back surface 14 of the tape 2 have no adhesive property at room temperature, the cutting device 5 does not become uncut.

<C> Heating Step The cut label 7 is adsorbed on the peripheral surface of the transfer drum 6,
It is transferred to the sticking drum 8. The sticking drum 8 receives the label 7 from the transfer drum 6 and transfers the label 7 to a sticking point on the container 9. The label 7 adsorbed on the peripheral surface of the sticking drum 8 receives hot air from the heating device 10, and the heat-sensitive adhesive band 15 and the heat-sensitive adhesive portion 16 are provided with adhesiveness.

<D> Sticking Step When the start end of the label 7 meets the container 9, the container 9 is forcibly rotated. As a result, the heat-sensitive adhesive bands 15, 15 at the beginning of the label 7
After the heat-sensitive adhesive portion 16 starts bonding to the peripheral surface of the container 9, continuous bonding to the peripheral surface of the container 9 by the heat-sensitive adhesive bands 15 on the upper and lower edges of the label 7 proceeds.

In the past, if the entire length of the label was long, the rear part of the label was in a state of being lowered, but in the present invention, the label 7 is wound around the peripheral surface of the container 9 while maintaining the horizontality. Finally, the heat-sensitive adhesive band 15, 1 at the rear end of the label 7
The label 5 and the heat-sensitive adhesive portion 16 are superimposed and bonded to the front side of the leading edge of the attached label 7.

[0021]

Second Embodiment In FIG. 4, a heat-sensitive adhesive band 15 continuous along the longitudinal direction of the tape 2 may be additionally provided at the center of the back surface 14 of the tape 2 constituting the roll label 1.
Further, as shown in the figure, the heat-sensitive adhesive portion 16 may be formed continuously in the transverse direction of the tape.

[0022]

As described above, the present invention has the following effects. <B> On the back surface of the tape constituting the roll label, a heat-sensitive adhesive band is formed continuously along the longitudinal direction. Therefore, the adhesive relationship with the peripheral surface of the container can be maintained at the time of sticking, the rigidity of the entire label is increased, and a stable posture of the label can be maintained. Therefore, it is possible to adhere with high accuracy even at high speed. <B> The heat-sensitive adhesive band formed on the back surface of the label has no adhesive property at room temperature. Therefore, the operation of the machine can be performed smoothly without the tape or the label being adhered to the various drums or the cutting device being unable to be cut by the adhesive.
