Printer drive control systems
Solucions for printing lines from 1 to 12 colours, with mechanical transmission and register (cachepit), or with independent motors (gearless).
Digital synchronisms (Gearless drive systems)
Systems to virtually shynchronize virtually the machine shafts.
These solutions replace old mechanical transmissions between shafts. An encoder is mounted In the master shaft (main), while in the slave shafts (secondary) the conventional motors are replaced with servomotors driven by a Motion Control system.
With the digital synchronism an electronic ratio is established between shafts in a virtual and flexible form, that can be changed at any time, even when the machine is operating.
The elimination of mechanical transmissions offers a wide range of advantages:
- Avoid printing inaccuracies originated when the gears start wearing off.
- Minimizes stopping time for format changeover.
- Allows increasing the machine speed with total precision and maximum printing quality.
Multishaft drive systems
Drive systems to synchronise multiple shafts in position and speed between them and with the main machine shaft.
This system implements one main virtual shaft to synchronize the rest of machine shafts in position and speed, enabling very high precision register controls without mechanical gear ratios, and allowing modifications on the virtual ratios with the machine in operation.
Register control
Allows to perform a modification on a material, taking as a reference a printed mark (register) in the material itself.
With the register control, the reference mark poistion in the material is detected, and upon the reading corrections in the systema are done automatically to maintain its position in respect to the original. This technology allows:
- Printing several colours keeping the posiction between them.
- Reprint on an existing printing in the same material side or the reversed.
- Apply a product (glue, adhesive, background,...) in a particular point in the material.
- Cut the material according to the printed size.
- To collage several sheets together in the same position.
- And in many other situations, where it is necessary to repeatedly perform a task in a concrete point in the material.
