BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus for cutting a strip without a backing sheet at predetermined intervals and sticking it to an adherend.

[0002]

2. Description of the Related Art Labels are roughly classified into two types: one is a strip-shaped backing sheet on which a plurality of labels are temporarily attached at predetermined intervals, and the other is a strip-shaped backing sheet when used. There is a backing-less band-shaped label (hereinafter referred to as a band-shaped label) in which an adhesive layer is formed on the back side (adhering side). Since the band-shaped label does not require a band-shaped backing sheet, it has recently been used as a label suitable for resource saving.

[0003] This strip-shaped label has a release agent layer such as silicone on the surface side, which is the printing surface, so that the outer surface and the inner surface which are overlapped when wound in a roll form are not stuck. In a conventional label sticking apparatus for band labels, a band label is wound in a roll shape, fed out from a supply reel to a printing unit, transported, and the end of the band label printed in the printing unit is placed between a pair of upper and lower cutting blades. A label piece is formed by feeding and cutting the same number of sheets. The leading edge of the cut label is back-fed to the printing unit. When returning to the printing start position, a single leaf label piece is formed by repeating the above printing operation, and the pulling roller pulls out the label piece from the cut portion.
It is sucked by a suction disk or the like and is attached to an adherend by a predetermined operation.

By the way, in order to improve the transportability of the back label when printing, it is necessary to transfer the printed label slightly downward. However, when the printed band-like label is transported slightly downward, there is a problem that the leading end of the label hangs down and does not enter between the pair of upper and lower draw-out rollers.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. When a printed label is transported slightly downward, the upper and lower pair of pull-out rollers can be used without hanging the leading end of the label. And a label sticking device for guiding between the rollers.

[0006]

SUMMARY OF THE INVENTION The present invention focuses on guiding the leading end of a hanging label upward, without a backing sheet having an adhesive layer formed on one side and a release agent layer formed on the other side. A belt-shaped label, a transfer means for transporting the band-shaped label, a cutting unit for cutting the band-shaped label, and a draw-out roller, and between the cutting unit and the draw-out roller, facing the adhesive layer surface of the band-shaped label. A label sticking device comprising a blowing means for blowing air.

According to the present invention, since the air is blown toward the adhesive layer surface at the leading end of the band-shaped label printed on the printing section, the air is guided between the pair of rollers of the pull-out roller. There is no problem such as that the leading end of the label hangs down and the label is not sucked to the suction disk, and the label can be printed and attached smoothly.
