Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a label pasting device for pasting a label on the circumferential surface of a cylindrical or cylindrical article.

BACKGROUND ART Labels printed with the manufacturer, product name, trade name, etc. are affixed to the containers of dry batteries and tablet medicines that are currently widely used. Taking a small dry battery of AA size or smaller as an example, as shown in Figure 1, prepare a label 1 with a trade name etc. printed on one side in advance, and label it on one side (back side).
As shown in Figure 2, the adhesive 2 made of glue was applied in two or three stripes, and the surface to which the adhesive was applied was wrapped around the finished unit cell 3, which was the article. .

It is inefficient to manually apply labels to cylindrical or cylindrical articles of this type, not just dry cells, so a dedicated label applicator is generally used. This label pasting machine uses a transfer roller to transfer an adhesive made of starch paste from labels stacked on a hopper to the end surface of an attachment provided on a segment, and uses the adhesive strength of the adhesive to remove the labels from the hopper. Draw out one by one,
After that, it is transferred upside down while being peeled off with a nail to a rotary disk that rotates at the same circumferential speed as the segment. Thereafter, labels were attached to the articles carried by an index disk-shaped article supply roller that rotated cross-rotated with the rotary disk while rotating the articles.

Problems to be Solved by the Invention However, in this method, since the adhesive is starch paste, it is necessary to press the label onto the article until the adhesive strength is sufficiently exerted. Therefore, it is not suitable for increasing the speed of label pasting, and requires a claw mechanism, a crimping mechanism, etc., making it mechanically complex and requiring a lot of time for maintenance and maintenance of the machine. .

The present invention aims to solve such conventional problems and to attach labels to articles at high speed by using a hot melt adhesive as an adhesive.

Means for Solving the Problems In order to achieve the above object, the present invention is characterized in that a label pasting device is constructed from the following elements. In other words, there is a manganese for stacking and storing a large number of labels, a star-shaped segment with a plurality of arm-shaped attachments that have a vacuum suction mechanism and a swinging mechanism, and that takes out labels one by one from the bottom of the manganese, and a star-shaped segment that is adsorbed to the attachment. a pasting roller that transfers the printed label onto its surface using a built-in vacuum suction mechanism, a transfer roller that transfers the hot melt adhesive to the label on the pasting roller, and a label that has the hot melt adhesive transferred thereon. A cylindrical or cylindrical article to be labeled at a position is held in an arc-shaped article holder,
It consists of an index disk-shaped article supply roller that rotates at a rotational peripheral speed faster than the rotational peripheral speed of the pasting roller, intersecting with the pasting roller.

Function: With a device configured like this, a label transferred from a hot-melt adhesive is affixed to an item, so there is almost no waiting time for the adhesive to develop, and the label can be affixed to the item at high speed. can be done.

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

FIG. 4 is a diagram showing an outline of a label pasting device according to an embodiment of the present invention, and 4 is a manganese for storing labels, and a claw 5 is provided at the lower end for peeling off and taking out the labels one by one. ing. A segment 6 is equipped with a vacuum suction mechanism and a swinging mechanism, and has a plurality of star-shaped arm-like attachments 6a for taking out the labels 1 one by one from the manganese 4. As shown in FIG. 5, the label 4 is inserted into the underside of the manganese 4 by pushing open the claw 5, and the label 4 is attached to the segment itself. By means of a swinging mechanism in which the arm-shaped attachment is swung by a grooved cam, the arm-shaped attachment 6a that has attracted the label 1 swings from side to side in a oscillating manner to push open the gap between the claws 5 and pull out the label 1.

The star-shaped segment 6 that has attracted the label 1 to the tip of the arm-like attachment 6a in the state shown in FIG. 5 rotates in the direction of the arrow in FIG. The front side of the label is attracted and the label is transferred from the attachment to the roller 7 with the back side facing the front side. On the back side of the label 1 adsorbed on the pasting roller 7, the hot melt adhesive 2 is transferred in two stripes. Figure 6 shows the adhesive application section, which includes a transfer roller 8 that stores hot-melt adhesive 2 inside and is placed so that a portion thereof is immersed in it, and the adhesive on the surface of the transfer roller that is applied according to the size of the label. It is equipped with a scraper 10 that leaves two or three streaks and scrapes off the rest. This transfer roller 8
As shown in FIG. 4, when the transfer roller 8 faces the pasting roller 7 and faces the back surface of the label 1, it comes into contact with the roller 8 to transfer and coat the adhesive onto the back surface of the label 1. After the adhesive is applied to the back side of the label, the pasting roller 7 further rotates and passes through the article supply roller 9.
The cylindrical article 11 transferred from a is held in the semicircular recess and comes into contact with the cylindrical article 11 of the article supply roller 9b, which has a faster circumferential rotational speed than the roller 7. This state is as shown in FIG. 7, and when the article 11 comes into contact with the label 1 of the roller 7, the adsorption function of the label 1 is canceled and the rotation peripheral speed of the article 11 is faster than the moving speed of the label 1. The label 1 is wrapped around the article 11, and labeling is completed instantly.

Reference numeral 12 in FIG. 7 is a fork-shaped jig that lifts the cylindrical article 11 from the concave portion of the roller 9b and brings it into contact with the label 1, and also serves as a guide for carrying out the article 11 after the label has been attached.

Effects of the Invention According to the label pasting device of the present invention, the vacuum suction mechanism of the arm-shaped attachment and the swinging motion left and right move the claws as a stopper at the bottom of the magazine from the lower part of the magazine where the labels are stored. The push-open oscillation mechanism allows the label to be taken out without bending, and by transfer-coating hot-melt adhesive onto the taken-out label, it is possible to attach labels to cylindrical or cylindrical articles at high speed. Depending on the rotational speed of the rollers and article supply rollers, it is possible to apply 600 to 700 labels per minute. Furthermore, since the mechanism is simple, maintenance can be easily performed.
