(Operation of Example 1)
In the label sticking device U of Example 1 having the above-described configuration, the label member L at the temporary peeling position is temporarily peeled (see ST11 (2) and ST12 (2) in FIG. 6), and the temporarily peeled label. The label member L is peeled from the release sheet S by subjecting the member L to main peeling at the peeling position (see ST11 (1), ST12 (1), ST13 in FIG. 6). Therefore, in the label sticking device U of Example 1, when the adhesive L2 has a higher adhesive force than when the temporary peeling process is not performed, or when the label member main body L1 is softly peeled off. Even when the material is difficult, the label member L can be reliably peeled from the release sheet S.

Moreover, in the label sticking apparatus U of Example 1, it peels temporarily by the ejection of air, this peels in the state which adsorb | sucked the upper surface of the label member L of the said peeling position by the suction of air, or the said label sticking member H Since the adhesive L2 of the label member L and the temporary peeling device KHS or the peeling and sticking device HHS are non-contact, temporary peeling, main peeling, and sticking can be performed. Therefore, in the label sticking device U of Example 1, each member of the temporary peeling device KHS and the peeling sticking device HHS is soiled by the pressure-sensitive adhesive L2, or the pressure-sensitive adhesive L2 is soiled and the adhesiveness is reduced. Further, it is possible to reduce the subsequent label member L from being contaminated by the respective members.
Moreover, in the label sticking apparatus U of Example 1, in the temporary peeling process, air is ejected to the label member L while being pressed by the label pressing member 4 except for the temporary peeling portion Lb of the label member L. Compared with the case where a strong force is applied to the entire label member L by squeezing, pushing up the lower surface, or squeezing it as in the prior art, the label member L is damaged by bending wrinkles or the like. Can be reduced.

Moreover, in the label sticking apparatus U of Example 1, since the said temporary peeling position is arrange | positioned in the said label conveyance direction Ya upstream of the said peeling position, the said temporary peeling which peels the label member L of the said temporary peeling position temporarily The process and the main peeling process for peeling the label member L at the peeling position can be performed in parallel (see ST11 and ST12 in FIG. 6). Therefore, in the label sticking apparatus U of Example 1, the delay of the timing of the label sticking process due to the temporary peeling process is reduced, and the label sticking process (see ST1 to ST6 in FIG. 5) is the flow of the production process. The temporary peeling process can be executed without affecting the process work time when viewed as work, the so-called tact time.
Moreover, in the label sticking apparatus U of Example 1, the label conveying direction Ya from which the temporary peeling portion Lb of the label member L is first peeled at the time of final peeling by the temporary peeling portion retracting groove 4b of the label pressing member 4 is provided. Since it is set to the right end portion (+ Y end portion) that is the upstream side, it can be reliably peeled off from the temporary peeling portion Lb during the main peeling.
