Abstract
The present invention relates to a blank joining module for a converting machine. The blank joining module comprises an upper feeder device configured to feed and transport an upper blank (2b) and a lower blank (2a) towards a junction point (J) where the upper blank is superposed onto the lower blank. The blank joining module comprises a register control system comprising a sensing system and a position correction device (86) configured to displace the upper blank to be aligned to the lower blank.
Claims15
A blank joining module comprising:
- an upper feeder device configured to feed an upper blank,
- a lower feeder device configured to feed a lower blank,
- an upper conveyor system configured to transport the upper blank from the upper feeder device,
- a lower conveyor system configured to transport the lower blank from the lower feeder device, the upper and lower conveyor systems being configured to transport the upper and lower blanks towards a junction point where the upper blank is positioned onto the lower blank, and
- a register control arrangement comprising a sensing system and a position correction device,
- wherein the sensing system comprises an upper transfer sensor configured to detect a passage of the upper blank and a lower transfer sensor configured to detect a passage of the lower blank, and
- wherein the register control arrangement further comprises a control unit and a memory, the control unit being configured to receive detection signals from the upper and lower transfer sensors and calculate a total relative displacement between the upper blank and the lower blank, the control unit being further configured to activate the position correction device to provide a correction displacement to the upper blank such that the upper blank is displaced to be aligned to the lower blank, and
- wherein the position correction device comprises a cleat belt provided with an abutment, and wherein the control unit is configured to either position the abutment to abut against a front edge or a rear edge of the upper blank such as to modify a position of the upper blank in a direction of transportation.
