  • the bag making and packaging machine 100A is different from the bag making and packaging machine 100 according to the first embodiment in the arrangement position of the first sensor 91.
  • the first sensor 91 is disposed downstream of the vertical seal mechanism 70 and upstream of the cutting mechanism 80.
  • the cutting mechanism 80 can use the detection signal of the first sensor 91 arranged upstream of the cutting mechanism 80 itself and in the vicinity of the cutting mechanism 80 in order to determine the timing for performing the cutting operation. . Therefore, since the length of the conveyance path from the first sensor 91 to the cutting mechanism 80 is short, the measurement error is less likely to affect the position of the film F grasped by the control circuit 200. As a result, the cutting mechanism 80 can operate with more accurate timing.

  • the third sensor 93 is for detecting the mark M in order to specify the timing for operating the print inspection mechanism 40.
  • the third sensor 93 is disposed upstream of the print inspection mechanism 40 in the transport path, and specifically, is disposed between the print inspection mechanism 40 and the print mechanism 30.
  • the bag making and packaging machine 100B includes a print inspection mechanism 40 and a third sensor 93 corresponding thereto. Therefore, the information printed on the film F by the printing mechanism 30 can be confirmed with high accuracy.

Abstract

La présente invention concerne une machine de fabrication et d'emballage de sacs (100) qui comporte un mécanisme d'alimentation (10), une unité de maintien de rouleau (20), un mécanisme d'impression (30), un formeur (60), un mécanisme de joint longitudinal (70), un mécanisme de joint transversal (75), un mécanisme de coupe (80), un premier capteur (91) et un second capteur (92). Le mécanisme d'impression (30) imprime des informations sur un film (F). Le formeur (60) superpose deux côtés longitudinaux du film (F). Le mécanisme de joint longitudinal (70) crée un tube de film (FT) en liant les deux côtés longitudinaux. Le mécanisme de joint transversal (75) pince et joint le tube de film (FT), créant ainsi une section de joint transversal. Le mécanisme de coupe (80) coupe le tube de film (FT) au niveau de la section de joint transversal. Le premier capteur (91) détecte une marque sur le film (F) pour spécifier une position de coupe à laquelle le tube de film (FT) doit être coupé. Le second capteur (92) détecte une marque sur le film (F) pour indiquer une position d'impression à laquelle des informations prédéterminées doivent être imprimées.
