Abstract
A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.
Claims20
A converting machine used to convert sheet material into packaging templates for assembly into boxes or other packaging, the converting machine comprising:
- a converting assembly configured to perform one or more transverse conversion functions and one or more longitudinal conversion functions on the sheet material as the sheet material moves through the converting machine in a feed direction, the one or more transverse conversion functions and the one or more longitudinal conversion functions being selected from the group consisting of creasing, bending, folding, perforating, cutting, and scoring, to create the packaging templates;
- and
- a fanfold crease sensing mechanism configured to detect the presence and location of fanfold creases that exist in the sheet material, the fanfold crease sensing mechanism comprising one or more sensors, the one or more sensors being configured to detect the presence and location of the fanfold creases and distinguish between the presence and location of a fanfold crease and movement of the sheet material closer to or further away from the one or more sensors.
A method of converting sheet material into packaging templates for assembly into boxes or other packaging, the method comprising:
- detecting with one or more sensors the presence and location of a fanfold crease in the sheet material,
- distinguishing between the presence and location of a fanfold crease and movement of the sheet material closer to or further away from the one or more sensors;
- determining that the fanfold crease is within a predetermined or user configurable distance of a leading edge of the sheet material;
- cutting off a predetermined or user configurable length from a leading end of the sheet material to remove the fanfold crease;
- and
- performing one or more conversion functions on remaining sheet material to form the packaging template.
A method of converting sheet material into packaging templates for assembly into boxes or other packaging, the method comprising:
- detecting the presence and location of a fanfold crease in the sheet material;
- predicting the location of a subsequent fanfold crease in the sheet material;
- determining that the subsequent fanfold crease would be within a predetermined distance of a trailing edge of a packaging template formed from the sheet material;
- cutting off a predetermined length from a leading end of the sheet material to move the subsequent fanfold crease further from the trailing edge than the predetermined distance;
- and
- performing one or more conversion functions on remaining sheet material to form the packaging template.
A converting machine used to convert sheet material into packaging templates for assembly into boxes or other packaging, the converting machine comprising:
- a converting assembly configured to perform one or more transverse conversion functions and one or more longitudinal conversion functions on the sheet material as the sheet material moves through the converting machine in a feed direction, the one or more transverse conversion functions and the one or more longitudinal conversion functions being selected from the group consisting of creasing, bending, folding, perforating, cutting, and scoring, to create the packaging templates;
- a fanfold crease sensing mechanism configured to detect the presence and location of fanfold creases that exist in the sheet material, the fanfold crease sensing mechanism comprising one or more sensors, the one or more sensors being configured to detect the presence and location of the fanfold creases and distinguish between the presence and location of a fanfold crease and movement of the sheet material closer to or further away from the one or more sensors;
- and
- a control system configured to receive readings from the one or more sensors and cause the converting assembly to cut off a leading end of the sheet material if:
- the sensing mechanism detects the presence of a fanfold crease within a predetermined or user configurable range of a leading edge of the sheet material;
- or
- the control system predicts that a fanfold crease will be within a predetermined or user configurable range of a trailing edge of a packaging template.
