Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for attaching a label for sealing an opening of an envelope or a bag (hereinafter simply referred to as an envelope in the present invention) to an opening of an envelope. In this case, the attached label has a separate paper attached to the adhesive part for sealing.

[Prior art]

Envelope sealing methods include gluing and double-faced tape (double-sided adhesive tape). There are two types of gluing: those that create an adhesive effect by applying water, and those that can be sealed directly by pressure bonding.Double-face adhesives are adhesives that are bonded by peeling off the separate paper. However, gluing is sensitive to humidity and pressure and has poor retention. Adhesion is also weak. Additionally, double faces have the disadvantage of being expensive.

[Object of the present invention]

In the present invention, a folded part (so-called tongue) is integrally provided at the opening of the envelope, and glue is applied there.
Instead of attaching a double face, the envelope or bag does not have a folded part, and a separately prepared sealing label with one side of the adhesive side is attached to this area to form the sealing part, and the sealing label is attached to the envelope. Regarding how to install.

[Means for achieving the present invention]

Three kinds of cuts (X, Y, and Z) are made in advance in a strip made of a strip of label base paper with adhesive on one side and a strip of separate paper pasted. It consists of the process of cutting out individual sealing labels with separate paper from the strip by simply making cuts, and simultaneously attaching the labels to the openings of envelopes that have been separately transported there.

[Explanation of Examples]

The method of the present invention will be specifically explained along with the sealing label roll used in the present invention and an automatic label attaching device using the same.

Figures 2 and 3 show sealed labels 1 by the method of the present invention.
The sealing label 1 is shown attached to the opening of the envelope 2, and the sealing label 1 is attached by adhesive using an adhesive portion 3 having a predetermined width. Note that symbol 4 indicates the label body, and symbol 5 indicates the separate paper.

The envelope 2 provided with the sealing label 1 in this manner is used as shown in FIGS. 4 and 5. That is, after the separate paper 5 is peeled off from the label body 4 to expose the adhesive surface of the label, it is folded and pasted on the opposite side of the opening as shown in the figure to close the opening.

Sealing with a label eliminates the need to create a cumbersome folded part (tongue) on the envelope side, and also has the advantage that various instructions and commercials can be printed on the label. It has been widely used in general bags.

FIG. 6 shows a sealing label roll used in the present invention, which is a band-shaped body 7 made by pasting a separate paper 5 similar to but slightly wider on a band-shaped label base paper 6.
is wound into a roll. An adhesive is applied to one side (lower side in the figure) of the label base paper, and a separate paper is pasted to that side. Figure 7 shows a concrete example of the strip, with separate paper 5
Since the label base paper 6 is attached with one side in the longitudinal direction aligned (referred to as the base line), a first fin portion 8 (width b) consisting only of the separate paper 5 is formed on the opposite side. Furthermore, three types of score lines X, Y, and Z are formed in advance on the strip 7. Cut line X
is applied in the longitudinal direction of the strip 7 parallel to the base line at a position a width c from the base line, that is, at the overlapping portion of the separate paper and the label base paper, and only the separate paper 5 is cut. As a result, the second fin portion 9 of width c
is formed. Note that the width c is equal to the width of the adhesive part of the label exposed when the second fin part 9 is peeled off, that is, the width of the adhesive part 3 to the envelope. Cut line Y is the strip 7
They are arranged in the transverse direction for each width w required for sealing, and both the separate paper 5 and the label base paper 6 are cut. However, as shown in the figure, the length is longer than the width a of the strip 7 by d on both sides. The cut line Z is continuous with the cut line Y and crosses the second fin portion 9, and cuts only the label base paper 6. That is, in the strip 7, the label base paper 6
is cut into individual labels in advance along cutting lines Y and Z, and a second fin portion 9 is formed on the separate paper 5 along cutting lines X. However, since the separate paper 5 is cut in the longitudinal direction and the label base paper 6 is cut in the transverse direction, as long as both are stuck together, they will not come apart.

Now, this formed strip 7 can be used as a sealing label.
It is wound up into a roll and loaded into an automatic label attaching machine (FIG. 1). The strip 7 pulled out from the roll is set in a rewinder 10. The presence or absence of the strip 7 is detected by the sensor 11, and if it is not detected, the motor 12 rotates for a certain period of time and the strip 7 is sent out. At the same time as the strip 7 is fed by the feeding belt 13, the first fin 8 of the separate paper 5 is cut in the longitudinal direction of the strip by the slitter 15 on the slitter receiving roll 14 (line X' in FIG. 7). . The line X' passes inside the width d and intersects the cut line Y. However, a hook portion 16 (FIG. 8) is formed with the edge of the label base paper 6 by leaving a width e. That is, d>e. The cut first fin portion 8 is pulled out downward by a pulling roll. The other second fin portion 9 is pulled out and peeled off by the slitter receiving roll 14 and the presser roll 17. As a result, the first and second fins 8 and 9 are removed from the strip 7 and separated into individual sealing labels 18 along the cut lines Y and Z. The sealing label 18 alone includes a label, a separate paper provided with a hook portion, and an adhesive portion 3 formed by peeling off the second fin portion 9. The sealed label 18 is fed by a label feeding roll 19 with a one-way clutch, and stops when detected by a sensor 20.

The envelope 2 to which the sealing label 18 is to be attached is fed automatically or manually through the insertion port 21, placed on a belt by the pull roll 22, and conveyed. At the same time as the sensor 23 detects the bag, the sealing label 18 starts, and the sealing label and the bag merge with the adhesive roll 24 to form the sealing label 1.
8 is attached to the opening of the envelope 2 (see also Figures 2 and 3). The sealing label 18 is thus indicated by the symbol 1 in FIGS. The attached sealing label 18 is ejected at the same time as the envelope, but the conveyance speed of the envelope is faster than the sealing label 18.
In other words, since the transport speed is higher than the conveyance speed of the strip 7, after the sealed label 18, which is continuous as a strip, is slitted (after the cut of 25 to stop. Note that since the label feed roller 19 is a one-way clutch, it follows the speed of the bag.

The envelope 2 and sealing label 18 are conveyed by a drive motor 26. The sealing label 18 is conveyed and stopped via a clutch brake, which is turned on and off. Of course, an independent motor may be used for conveying the sealed label 18.

As described above, the method of the present invention is achieved by making X, Y, and Z score lines in advance on the above-mentioned strip 7, and then making the X' score lines with a slitter when using the strip. The label base paper 6 is divided into individual sealed labels 18 on the separate paper 5, and the first and second fins 8 and 9 formed on both sides of the strip 7 are pulled in and separated, thereby transporting the strip 7. At the same time, the adhesive portion 3 and the hook portion 16 are formed on the sealed label 18. Then, the individual sealing labels 18 are attached to the envelopes sent there.

[Effects of the present invention]

In the present invention, X, Y, Z
Since the cut is made in advance, even if the automatic label attaching device is a conventional one, it can be implemented by simply modifying the slitter 15 and the slitter receiving roll 14 by newly arranging it. Moreover, the attached label main body 4 has separate paper 5 stuck to the necessary places, and has a hook part 16, which makes it convenient for peeling off the separate paper.

Since normal adhesive base paper can be used as the label base paper, low-cost sealed labels can be obtained.

Since the slitter in the automatic label attaching device cuts only the separate paper of the strip, no adhesive or the like adheres to the blade.
