Moreover, at least one of the first support mount and the second support mount is displaced in the thickness direction by the displacement means, thereby adjusting the position at which the protective label is attached to the label.

(Effects of the Invention) According to the present invention, since the position at which the protective label is attached to the label can be adjusted by the displacement means, the position at which the protective label is attached to the label can be easily adjusted.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is an illustrative diagram showing an embodiment of the present invention. This protective label pasting apparatus IO includes a base 12, and the base 12 includes a guide roller 14a.

14b, 14C and 14d are rotatably supported at intervals.

A continuous label body 16 is guided to these guide rollers 14a-14d. This label series 16 is particularly suitable for the second
As shown in FIG. A and FIG. 2B, a strip-shaped release mount 18 is included as a first support mount, and a release mount 18 is included.
includes a belt-shaped sheet material such as paper 1 synthetic resin, and a release agent layer (not shown) is formed on the surface of the sheet material by applying a release agent such as silicone. Labels 20 are temporarily attached to the release mount 18 at predetermined intervals in the longitudinal direction thereof with an adhesive layer 2Qa made of, for example, a pressure-sensitive adhesive. Note that a printed layer 20b is formed on the surface of the label 20 by printing, for example, characters 9 and figures thereon.

As shown in FIG.
is guided between a feeder roller 26 and a nip roller 28, which constitute part of the first transfer means and pressing means. This feeder roller 26 is connected to a motor (not shown) via, for example, a belt. Further, the nip roller 28 is urged toward the feeder roller 26 by a spring 30. Therefore, by rotating the feeder roller 26, the hollow continuous body 16 can be transported in its longitudinal direction.

Note that the guide roller 14b described above is supported by the base 12 so as to be vertically displaceable, and when the continuous label body 16 is being transported with normal tension, it is placed downward by its own weight. Therefore, when the continuous label body 16 is pulled with an abnormally large force, for example, when the continuous label body 16 is not transported, the guide roller 14b
Displaced upwards. Furthermore, guide roller 14b' (7)
A limit switch (not shown) is provided on the travel path. This limit switch is connected to the above-mentioned motor for transporting the label series 16.

Therefore, if the label continuous body 16 is pulled with an abnormally large force, the limit switch is activated to stop the transport of the label continuous body 16, thereby cutting the label continuous body 16 with an abnormally large tensile force. It is possible to prevent this from happening.

In the protective label pasting device 10 of this embodiment, the label continuous body 16 can be displaced in the transport direction by a displacement means including the roller 22, so the displacement means will be explained next.

The roller 22 is rotatably mounted on a shaft 32, as shown in FIG. This shaft 32 has a collar 34 formed at one end thereof, and a male threaded portion 36 formed at one end thereof. The male threaded portion 36 of the shaft 32 is inserted into a vertically long hole 12a formed in the lower part of the base 12. The male threaded portion 36 is screwed into a female threaded portion 38a of a rectangular plate-shaped female threaded member 38 on the back side of the base 12. This shaft 32 and roller 22 are therefore attached to the base 12.

Furthermore, stopper members are formed on both sides of the hole 12a on the back surface of the base 12, and the female screw member 38 is held by these stopper members so as not to rotate. On the other hand, a knob 42 for rotating the shaft 32 is formed at the other end of the shaft 32. Therefore, by rotating the knob 42, the male threaded portion 36 of the shaft 32 can be loosened from the female threaded portion 38a of the female threaded member 38. In this state, the roller 22 can be displaced along the hole 12a of the base 12 in the direction shown by arrows A and B in FIG. 1 (vertical direction).

When the roller 22 is displaced in the vertical direction, the label continuous body 16 hooked on the roller 22 is displaced in its thickness direction, and therefore the feeder roller 2
6 and the nip roller 28 in the direction of transport thereof. For example, if the roller 22 is displaced in the direction indicated by arrow A in FIG. 1 (upward), the label continuous body 16 is displaced in the advancing direction of its transport direction. Conversely, if the roller 22 is displaced in the direction shown by arrow B in FIG. 1 (downward), the continuous label body 16 will be displaced in the return direction of its transport direction. Note that when displacing the continuous label body 16, the nip roller 28 may be separated from the feeder roller 26 against the spring force of the spring 30. In this case, the cam 31 provided between the nip roller 28 and the spring 30 is
This is done by rotating a shaft 31a fixed to the cam 31.

Furthermore, this protective label pasting apparatus 10 is provided with a holding reel 44 on the top of the base 12. A continuous protective label 46 is attached to this holding reel 44.
is held in a roll. This protective label series 46 includes, in particular, a strip-shaped release mount 48 as a second support mount, as shown in FIGS. 4A and 4B. This release mount 48 includes a belt-shaped sheet material such as paper 3 synthetic resin, and a release agent layer (not shown) is formed on the surface of the sheet material by applying a release agent such as silicone. has been done. Protective labels 50 for protecting the surface of the label 20 described above are temporarily attached to the release mount 48 at predetermined intervals in the longitudinal direction with an adhesive layer 50a made of, for example, a pressure-sensitive adhesive. There is.

Note that this protective label 50 allows the label 20 to be seen through it.
In order to make the printed layer 20b visible, it is made of a transparent or translucent material such as synthetic resin.

As shown in FIG. 1, one end of the protective label continuous body 46 is unwound from the holding reel 44, and is passed through guide rollers 52a, 52b, and 52c to a roller 54 that constitutes a part of the displacement means. It is further guided to a peeling plate 58 as a peeling means via a guide roller 56.

On the peeling plate 58, as shown in FIG.
Thereby, the protective label 50 is peeled off from the peeling mount 48 toward the label 20 described above.

A protective label 50 is then pasted onto the label 20 between the feeder roller 26 and the nip roller 28, as shown in FIGS. 6A and 6B.

Furthermore, as shown in FIG. 1, the sharply folded release liner 48 is guided through a guide roller 60 between a feeder roller 62 and a nip roller 64, which constitute a part of the second transport means. This feeder roller 62 is connected to a motor (not shown) via a belt (not shown), for example.
is connected to. Further, the nip roller 64 is urged toward the feeder roller 62 by a spring 66. Therefore, the release liner 48 is conveyed in the longitudinal direction while being sandwiched between the feeder roller 62 and the nip roller 64. Then, the transferred release mount 4
8 is guided to a take-up reel 70 provided on the upper part of the base 12 via a guide roller 6B, and is wound there into a roll shape.

Furthermore, in the protective label pasting device 10 of this embodiment,
Protective label series 4 by displacement means including rollers 54
6 can be displaced in its transport direction, then,
The displacement means will be explained.

Like the roller 22 described above, the roller 54 is also attached to the base 12 so as to be movable in the directions shown by arrows C and D in FIG. 1 (up and down). That is, this roller 54
is rotatably attached to a shaft 80, as shown in FIG. This shaft 80 also has a collar 82 formed at one end thereof, and a male threaded portion 84 at one end thereof.

The male threaded portion 84 of this shaft 80 is inserted into a vertically long hole 12b formed in the upper part of the base 12.

Furthermore, this male threaded portion 84 is screwed into a female threaded portion 86a of a rectangular plate-shaped female threaded member 86 on the back side of the base 12, thereby attaching the shaft 80 and the roller 54 to the base 12. Further, on the back surface of the base 12, on both sides of the hole 12b, there are formed a bar member for preventing the female screw member 86 from rotating. Furthermore, a knob 90 for rotating the shaft 80 is formed at the other end of the shaft 80.

Therefore, by loosening the male threaded portion 84 of the shaft 80 from the female threaded portion 86a of the female threaded member 86 with the knob 90,
The roller 54 can also be displaced in the vertical direction along the hole 12b of the base 12.

By displacing the roller 54 in the vertical direction, the protective label continuous body 46 hooked on the roller 54 can be displaced in its thickness direction, and the feeder roller 26
and nip rollers 28 in the transport direction. For example, move the roller 54 to arrow C in FIG.
If it is displaced in the direction indicated by (downward), the protective label continuous body 46 is displaced in the advancing direction of its transport direction. Conversely, if the roller 54 is displaced in the direction indicated by the arrow in FIG. 1 (upward), the protective label continuous body 46 is displaced in the return direction of its transport direction. In addition, when displacing the protective label continuous body 46, the nip roller 64 may be separated from the feeder roller 62 against the spring force of the spring 66.

With this label attachment device W10, if the position of the protective label 50 deviates from the position of the label 20, the positions can be easily adjusted.

For example, as shown by the one-dot chain line in FIG.
If the protection label 50 is delayed too much, the roller 22 of the displacement means is displaced in the direction shown by arrow B in FIG. 1 to displace the label continuous body 16 in the return direction of the transport direction,
The protective label continuous body 46 may be displaced in the advancing direction of the transport direction by displacing the roller 54 of the displacing means in the direction shown by arrow C in FIG. By doing so, the protective label 50 can be attached to the label 20 of the label continuous body 16.

Conversely, as shown by the two-dot chain line in FIG.
If the label 20 lags behind the label 20 too much or if the protective label 50 advances too far relative to the label 20, the roller 22 of the displacement means is displaced in the direction indicated by the arrow in FIG. 1 to transport the label continuous body 16. Alternatively, the roller 54 of the displacement means may be displaced in the direction indicated by the arrow in FIG. 1 to displace the protective label continuous body 46 in the return direction of the transport direction.

In addition, in the above-mentioned embodiment, the displacement means is the label continuous body 16.
The displacing means is provided in one of the transfer paths of the peel-off mount 18 of the label continuous body 16 and the peel-off mount of the protective label continuous body 46, respectively. All you have to do is stay there. in this case,
To adjust the position of the protective label 50 relative to the label 20, the label continuum 16 and the protective label continuum 46 are
This is done by adjusting the position of one of the transport directions.
