Cable guides for reliable media supply for large-format printers

Heleva is not just a sheet feeder for large format printers. Behind the machine is an intelligent management system that carries out loading commands from the printer or sends it information about the media to be processed.
However, the focus is on transporting the print media, which can weigh up to 20 kg and be 20 mm thick, from the pallet to the large-format digital printer. A lifting table automatically adjusts to the height of the stack. The suction cups take the sheets from the stack, place them on the table and align them perfectly for feeding. This cycle is repeated until the print queue is complete or the material on the pallet has been used up. Once the workflow is configured, the process can run fully automatically and unattended.
As large format printers have reached a very high level of productivity and require a full-time operator due to their high speed, the feeding systems run around the clock. For this reason, the repetitive feeding process must function completely failure-free, which also affects the cables and cable guides on the lift table. Every time the suction cups move to the pallet and back, the cable routing moves with them.

Heleva boosts the potential of the most advanced digital printers, making them productive around the clock while minimising the need for monitoring and increasing productivity. The automation of the relatively simple and repetitive process significantly increases the efficiency of print shops.
As the process runs autonomously and the necessary productivity can be achieved first, a reliable solution for the line feed also had to be found. Many cycles required low-wear parts that support the smooth and precise movement of the lift table and grippers. Only in this way can the media supply systems be operated profitably.
Lightweight plastic-energy chains are used to guide the chainflex® cable to the power supply, even in tight installation situations and bend radius. They enable Heleva's particularly short feeding times and therefore more competitive processes in the printing industry.
