  • the control unit 21 separates the front end 12a of the label 12 from the backing paper 11 and removes the sheet 10 . is reversed to start a preliminary peeling operation to return the label 12 onto the backing paper 11 , and after the preliminary peeling operation, the sheet feeding mechanism 16 is controlled to peel off the front end 12 a of the label 12 from the backing paper 11 .
  • the label applicator 3 can start the preliminary peeling operation at the timing when the tension of the backing paper 11 becomes smaller as the outer diameter of the take-up roll 26 increases and label 12 sticking failure tends to occur. , the occurrence of label 12 sticking failure can be prevented. Moreover, the label sticking device 3 can improve the sticking efficiency of the labels 12 by avoiding performing the preliminary peeling operation on all the labels 12 on the roll sheet.
  • the control unit 21 of the label applying device 3 of the embodiment detects the winding speed based on the rotation speed of the winding roll 26 detected by the rotation detection unit 44. It is determined whether or not the tension of the backing paper 11 wound on the take-up roll 26 at the starting end side has reached or exceeded a predetermined tension.
  • the rotation detection unit 44 serves both to detect the outer diameter of the take-up roll 26 and to detect the tension of the backing paper 11 when the backing paper 11 starts to be wound. An increase in the number of detection units can be suppressed, and the configuration of the sheet feeding mechanism 16 can be simplified.
  • control unit 21 of the label application device 3 of the embodiment controls the feeding speed of the sheet 10 when the outer diameter of the take-up roll 26 detected by the rotation detection unit 44 reaches or exceeds a predetermined outer diameter threshold value. Control the sheet feeding mechanism 16 to change. As a result, the operation of peeling the front end 12a of the label 12 by the peeling member 18 by the reference peeling amount can be corrected according to the tension of the backing paper 11, and the occurrence of label 12 sticking failure can be further suppressed.

Abstract

Le dispositif de pose d'étiquette comprend : un mécanisme d'alimentation qui présente un rouleau d'alimentation ayant enroulée dessus une feuille dans laquelle des étiquettes sont disposées sur un matériau de base ayant un matériau adhésif interposé entre eux, et un rouleau de prélèvement pour prélever le matériau de base de la feuille alimentée depuis le rouleau d'alimentation ; une unité d'impression qui effectue une impression sur les étiquettes ; un élément de libération qui libère les étiquettes du matériau de base de la feuille alimentée par le mécanisme d'alimentation ; un mécanisme de pose qui pose, au niveau de la surface circonférentielle externe d'un corps cylindrique, chacune des étiquettes ayant son extrémité avant dans le sens d'alimentation de la feuille libérée du matériau de base ; une unité de détection pour détecter le diamètre externe du rouleau de prélèvement autour duquel le matériau de base est enroulé ; et une unité de commande qui commande le mécanisme d'alimentation. Lorsque l'unité de détection détecte que le diamètre externe du rouleau de prélèvement est devenu supérieur ou égal à un diamètre externe prédéterminé, l'unité de commande commande au mécanisme d'alimentation de démarrer une opération de libération préliminaire pour libérer l'extrémité avant d'une étiquette du matériau de base, et déplacer la feuille vers l'arrière de sorte que l'étiquette est renvoyée au matériau de base, et, après l'opération de libération préliminaire, libère l'extrémité avant de l'étiquette du matériau de base.
