Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an adhesive activation device for a label without a mount, and more particularly to an adhesive activation device for a label without a mount that activates an adhesive by light irradiation.
[0002]
[Prior art]
In a label printer (not shown) for printing a bar code or the like, a label continuous body (not shown) in which a label is temporarily attached to a belt-like mount at a predetermined interval is used as a recording medium for normal use. It is loaded into the supply unit and printed on the label surface of the label continuum fed from the supply unit to the transfer path.
In this continuous label body, a release agent such as silicon is applied to one surface of a belt-like mount, and this surface and a surface coated with a pressure-sensitive adhesive are temporarily attached to one surface of the label at a predetermined interval. The other side of the label has a recordable printing surface.
Since the pressure-sensitive adhesive applied to the label is adhesive at room temperature, a mount is required to protect the pressure-sensitive adhesive until just before using the label.
[0003]
In addition, there are heat seal type labels and delayed type labels that activate the pressure sensitive adhesive by heating, but the heat seal type labels and delayed type label adhesives are used at room temperature. Because it is not sticky, no mount is required.
Further, when using such a label while printing, it is necessary to provide a heating device such as a heater for activating the adhesiveness toward the adhesive surface of the label inside the label printer.
[0004]
However, the label having the pressure-sensitive adhesive described above requires a mount on which a release agent is applied. Since the release agent is applied, high-quality paper is used, and the mount itself is expensive. In addition, after the label is peeled off from the mount and pasted on a product or the like, the mount becomes unnecessary and there is a problem that the mount is wasted.
[0005]
The adhesive for heat-seal type labels and delayed type labels is not sticky at room temperature and therefore does not require a mount, but a heating device is required inside the label printer. The surroundings become hot and there is a risk of human injury such as burns, and in order to prevent this, a shielding board for shielding heat is required.
Further, a large power source is required for heating, and thus the problem arises that the apparatus itself becomes large.
In addition, a standby time is required for the heat of the heating device to reach a predetermined temperature at the start of the work, and it is necessary to always preheat, resulting in a problem that the economic burden increases.
[0006]
[Problems to be solved by the invention]
The present invention has been considered in view of the above problems, and it is an object of the present invention to provide an adhesive activation device for a label without a mount, which does not require a mount, reduces the size of the entire device, and does not cause human damage such as burns. To do.
[0007]
Another object of the present invention is to provide an adhesive activation device for a label without a mount, which can improve work efficiency and further reduce the economic burden because no waiting time is required at the start of work. To do.
[0008]
[Means for Solving the Problems]
That is, the present invention pays attention to the fact that a mount is not required and that an adhesive that is activated by light is provided on the back surface of the label. The first invention is a label without a mount that is transported through a predetermined transport path. A photoactive adhesive is used as the adhesive provided on the back surface of the paper, a feeding means for feeding the label without the mount at a predetermined pitch, and an endless belt for transferring the label without the mount upstream of the feeding means are wound around a pair of rollers. The endless belt is provided with an opening in an appropriate shape at a predetermined interval, and a light irradiation means is provided between the rollers so that the photoactive adhesive is irradiated with light through the opening. An adhesive activation device for a label without a mount.
[0009]
A second invention is an adhesive activation device for a label without a mount, wherein the light irradiation means is infrared or ultraviolet.
[0010]
In the first and second inventions, the label without a mount can be cut and fed out.
Thus, the use of a photoactive adhesive eliminates the need for a mount, and the adhesive is activated by a simple method of light irradiation, so that the apparatus itself can be enlarged by providing a heating device or the like as in the prior art. It can be mounted on a small label printer. Furthermore, human injury such as burns is eliminated, workability is improved, and the economic burden is reduced.

Although not shown in any one of the pair of feeding rollers 31, 31, it is rotatably provided as the stepping motor is driven.
[0016]
Further, the single-sheet non-mounting label 6 cut at a predetermined pitch is controlled so as to be transported by a predetermined pitch by the feeding rollers 31 and 31 and stopped so that the strip-shaped non-mounting label 1 is removed. The length to be cut at a predetermined pitch is the length corresponding to the pitch of a black mark (not shown) provided on the label without mount, and the length is at least between the cutting means 11 and the feeding means 12. Are substantially the same or longer.
[0017]
Next, the operation will be described.
When the thermal head 15 is in the closed state, that is, when the label 1 without the mount and the ink film 17 are sandwiched, a desired print pattern such as a bar code and a character is sent to the thermal head. 15, the ink is transferred to the printing surface 4 of the label 1 without mount according to the printing pattern.
The label 1 without the mount is rotated while the platen roller 14 is rotated by a driving device (not shown) while being printed, and the label 1 without the mount is transferred by the cutting means 11. Are cut in the width direction (cutting step) to form a single-sheet non-mounting label 6.
[0018]
The single-sheet non-mounting label 6 is transferred toward the take-out port 13 by a pair of feeding rollers 31 and 31 which are feeding means 12 provided downstream of the transfer path 8 (feeding process), and is also a single-sheet mounting. Infrared light is irradiated to the surface of the photoactive adhesive 3 of the none label 6 by the light source 30 as the light irradiating means, and the photoactive adhesive 3 of the single-sheet mountless label 6 is activated (light irradiation step). .
The single-sheet non-mounting label 6 transferred to the outlet 13 can be taken out and pasted on a target product (not shown) because the light irradiation adhesive 3 is activated.
Further, the surface of the pair of feeding rollers 31 and 31 is subjected to a peeling treatment such as silicon so that the activated photoactive adhesive 3 is not attached.
A surrounding plate (not shown) or the like may be provided so as to surround the light source 30 so that the light from the light source 30 does not leak to the periphery except the adhesive surface.
[0019]
In this way, the photoactive adhesive that activates the adhesive by light is provided on the label without the mount, and by providing a simple means of light irradiation in the label printer, there is no human damage such as burns due to the conventional overheating device, In addition, even a small printer can be mounted, and no waiting time is required at the start of work, thereby improving work efficiency and reducing the economic burden.
