Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a labeling method using a label having a back surface coated with a water-soluble adhesive and a labeling machine therefor.

[0002]

2. Description of the Related Art Conventionally, for labeling with a labeling machine, a gluing label which is glued by a gluing mechanism, a heat sensitive label and a pressure sensitive label have been used.

[0003]

However, each of the conventionally used labels has its drawbacks. In the case of gluing labels, problems such as the trouble of controlling the amount of glue to be applied, the poor workability of cleaning the glue container of the gluing mechanism, the trouble of glue supply and workability, the trouble of purchasing and storing the glue, etc. However, a heat-sensitive label is a label that is difficult to manufacture because it is coated with hot melt on the back side and is expensive and expensive. Also, a pressure-sensitive label is coated with hot melt, and since a label paper is used in addition to the label paper, a heat-sensitive label It becomes more expensive than that, and since hot melt is used when recycling the container, there is a drawback that peeling of the label becomes difficult, which is an environmental problem.

[Means for Solving the Problems] In order to solve the above problems, when water-soluble glue is applied to the back surface of the label production and dried to produce a label, and when the label is attached by a labeling machine, moisture is not applied. Is applied or sprayed, the paste is activated, and then the paste is attached to the container. Therefore, the first means is a label magazine that stores a single-wafer label coated with water-soluble glue on the back side, a transfer mechanism that takes out the labels one by one and transfers them to the sticking section, and keeps the moisture on the adhesive surface of the label. A labeling machine is composed of a watering mechanism for applying or spraying. The second means is a feeding mechanism that feeds a strip-shaped label with a water-soluble adhesive applied to the back surface, a separating mechanism that separates individual labels, a transfer mechanism that transfers the separated labels to a sticking portion, and a label. The labeling machine is composed of a watering mechanism that applies or sprays water on the glue surface of the.

[0005]

The first means is to apply a water-soluble glue to the back surface of the label in the manufacturing process, store the individual labels processed into individual labels in the label magazine, and apply the vacuum force to the labels one by one from the label magazine. The label is transferred to the container transfer mechanism by the label transfer mechanism, and water is applied to or sprayed on the paste surface by the water addition mechanism to activate the dry paste, and then the label sticking unit is used. And attach it to the container that is carried by the container transport mechanism. The second means is to set a strip-shaped label, which is coated with water-soluble glue on the back surface of the label in the manufacturing process, in the label supply section, and feed the strip-shaped label to the separating mechanism in synchronization with the feeding mechanism. Individual labels separated from the strip-shaped label by the separation mechanism are held by the label transfer mechanism by vacuum force or the like and transferred to the sticking part, and water is applied or sprayed on the paste surface by the water adding mechanism in the middle thereof. After activating the dried glue, it is carried to the container transport mechanism unit, and attached to the container transported by the container transport mechanism.

EXAMPLES Examples of the present invention will be described below. FIG. 1 shows a plan view of a labeling machine using a single-wafer label. The labeling machine shown in FIG. 1 includes a label magazine 11 for storing single-wafer labels and a drum 21 for a label 1 transfer mechanism.
And a watering mechanism 3 for giving water to the back of the label, and a container 4
It is composed of a container transport mechanism 4 for transporting 1. Drum 2
1 is provided with a large number of suction holes for holding the sheet 1 by a vacuum force, and the vacuum force is appropriately generated in each suction hole as the drum 21 rotates.

Next, the operation of the labeling machine of FIG. 1 will be described. A drum 21 in which the label 1 at the leading end of the label magazine 11 is continuously rotated by the swing motion of the label magazine 11.
, Is held by suction on the outer periphery of the drum 21 by the vacuum force of the drum 21, and is conveyed to the container transport mechanism 4 by the rotation of the drum 21. On the way, water is applied to the dried glue surface on the back of the label 1 by the adjacent watering mechanism 3 on the outer periphery of the drum 21 or the spraying glue is activated, and then it is carried to the container transport mechanism 4 and attached to the container 41. Attached.

FIG. 2 shows a plan view of a labeling machine using a strip-shaped label. The labeling machine shown in FIG. 2 includes a label supply mechanism 12 for supplying a label 1a in a band shape, a feeding mechanism 5 for feeding the label 1a in a band shape by a driving roller and a pressure roller, and a label 1a in the band shape. Separation mechanism 6 for cutting or punching the label to separate it, drum 21 of the transfer mechanism for label 1, and water adding mechanism 3 for supplying water to the back surface of the label.
And a container transport mechanism 4 for transporting the container 41.

Next, the operation of the labeling machine of FIG. 2 will be described. The strip-shaped label 1a sent from the label supply mechanism 12 by the rotation of the drive roller of the feeding mechanism 5 is transferred to the separating mechanism 6 while synchronizing. It is fed, cut or punched by the separating mechanism 6 and separated from the belt-shaped label 1a, sucked and held on the outer periphery of the drum 21 by the vacuum force of the drum 21, and conveyed to the container conveying mechanism portion by the rotation of the drum 21. On the way, water is applied to the dried glue surface on the back of the label 1 by the adjacent watering mechanism 3 on the outer circumference of the drum 21 or the sprayed glue is activated, and then it is carried to the container transport mechanism 4 and attached to the container 41. Attached.

FIG. 3 shows a watering mechanism 3 using a sponge roller 31 for supplying water to the adhesive surface of the label 1. This causes water to permeate the outer circumference of the sponge roller 31, and the outer circumference of the sponge roller 31 is brought into rolling contact with the adhesive surface of the label 1 to give water to activate the adhesive. Also sponge roller
Instead of 31, a water absorbent material such as a cloth or paper roller may be used.

FIG. 4 shows a watering mechanism 3 for applying water to the glue surface by applying the spraying principle. This is because when air is sent to the nozzle 322, the water 34 in the tank 324 is sucked up by the water pipe 323 to be atomized and sprayed on the adhesive surface of the label 1 to activate the adhesive. If the water temperature is high, the activation of the glue will be quick.

FIG. 5 shows a heater for the water 34 in the tank 324.
The plurality of nozzles 3 are heated by 325 to generate steam, and the steam is sent from the air-pipe 326.
22 shows a watering mechanism 3 which is ejected from 22 to give water to the glue surface of the label 1. A belt conveyor may be used as the transfer mechanism for the label 1 instead of the drum 21.

EFFECTS OF THE INVENTION The labeling method and labeling machine of the present invention have the drawbacks of a gluing label, such as time and effort for managing the amount of glue to be applied, poor workability in cleaning the glue container of the gluing mechanism, and glue supply. It eliminates the troubles such as labor and workability, and the trouble of purchasing and storing the glue, and it is difficult to manufacture because hot melt, which is a drawback of heat sensitive labels, is applied to the back side, and the manufacturing cost is high. It is more expensive than a heat-sensitive label because it is coated with melt and a backing paper is used in addition to the label paper. Also, since hot melt is used when the container is recycled, peeling of the label becomes difficult, which is an environmental problem. Although it was also a problem, the label could be washed off by washing with water using a water-soluble glue, and many defects could be eliminated.
