Abstract

PROBLEM TO BE SOLVED: To eliminate the positional slipping or dropping of an adhesive label, and accurately affix the adhesive label at a specified location on an apparatus to be affixed by a method wherein the suction mechanism which is drawing the adhesive label is moved by a carrying actuator, then, the adhesive label is peeled, and moved to a specified location by an affixing actuator, and the adhesive label is pressed to the apparatus to be affixed. SOLUTION: A suction mechanism 12 which is drawing an adhesive label 1 is carried at a synchronized speed by a carrying actuator 8 and a label support paper feeding mechanism 3 which are controlled by a synchronous carrying control unit 14. When the adhesive label 1 reaches a corner part 5a of an adhesive label peeling plate 5 by the carrying, a label support paper 2 is peeled, and only the adhesive label 1 being drawn by the suction mechanism 12 is fed. Then, the suction mechanism 12 being equipped with a pressing mechanism 13 and an affixing actuator 7 are accurately stopped at specified locations. Then, by driving the affixing actuator 7, the suction mechanism 12 is pressed to an apparatus 9 to be affixed, and by doing so, the adhesive label 1 is affixed on the apparatus 9 to be affixed. For this reason, a favorable affixing precision can be obtained.

Reference numeral 12 denotes a suction mechanism, and the suction surface 12a is provided with a plurality of suction holes 12b.
The negative pressure is applied by, for example, a vacuum pump (not shown) to suck the adhesive label 1. The suction mechanism 12 is provided with a pressurizing mechanism 13 capable of varying the applied pressure. When the pressure-sensitive adhesive label 1 is sucked, the pressure mechanism 13 appropriately brings the suction-side surface 12a close to the pressure-sensitive adhesive label 1 and also makes the suction-side surface 12a close to the pressure-sensitive adhesive label 1a.
