A frequent and repeated maintenance of the doffer as well as checking and resetting the system has a significant impact on the machine efficiency, especially in the mid and long-term. If the doffing cycle is delayed, for instance due to an elongated servo disc belt the productivity of the spinning machine will drop and impact costs.
Productivity and performance of ring spinning machines highly depend on the auto doffer function. A quick and reliable doffing operation results in a better spinning mill performance.
The auto doffer works at a standard doffing cycle time of around 180 seconds. Being on time will make he spinning process more viable and optimizes costs. In addition, it leads to a smooth restarting of the machine with a higher starting spindle speed.
Rieter field data has shown that a complete doffer mainte-nance every eight years can extend machine lifetime by sev-eral years. To extend machine lifetime and safe money in the end, Rieter recommends to conduct regularly and repeatedly all the necessary maintenance activities such as lubricating, cleaning, re-setting and checking of parts
Rieter after-sales solutions for ring spinning machines enhance productivity at Hanif Spinning Mills and contribute to sustainability through extended machine lifetimes.
Keeping the doffing cycle time at its standard level of 180 seconds positively impacts production by several tons per year. In addition, it increases the machine lifetime.
