Portal payoff with remaining length mode

Another key component of the safety concept is the integrated machine guard, equipped with bumper strips (switch contact strips) that are secured with fail safe control assemblies. In the event of a collision with an object or person, the strip ensures an immediate stop of the traversing movement without halting the winding process. The absence of fixed fencing during winding operations without traversal also results in space savings. The pintles, the take-up bar and the take up pins can be exchanged with just a few simple steps, without any tools. Spare parts with complementary sizes are stored directly near the work area. The winder processes products with diameters ranging from 1 to 22mm.

Kurre Systems, a German provider of mechanical engineering solutions for the cable and wire industry, is enhancing its portal payoff with a new “remaining length” operation mode, to improve both safety and tool-free machine set-up. “In certain production and process steps, it is unavoidable to enter the winding area,” said sales engineer René Püschel. “However, from a safety perspective, this presents a challenge. Kurre Systems now offers an optimised payoff specifi- cally designed for such cases.” Using a special safety concept, the machine can be safely entered during operation to manually guide remaining lengths. By intentionally activating the mode with a key switch, the machine is set to “Remaining Length Operation”. In this mode, the system adjusts to predefined parameters and aligns with safety requirements: the rotational speed is reduced, the traversing movement is stopped and the pulling forces are limited. “In this state, the operator can perform tasks within the machine,” explained Mr Püschel. “This is made possible through the use of safety assemblies that ensure redundant protective mechanisms.” increases flexibility and sustainability in cable production without compromising safety. Particularly, the waste of the last few metres of usable length – for example, due to mechanical influences – is eliminated by manual guidance. Delicate products can also be precisely processed to the very end. As a result, the process avoids significant amounts of production scrap while simultaneously increasing efficiency.
