Log Accumulator Chain Lubrication system

A Tissue manufacturer wanted to improve the performance and reliability of their converting area and in doing so turned to Rotalube Systems Limited for assistance. The operating conditions of the Tissue manufacturing plant was dust laden, so the use of the machines conventional oil drip lubrication system was ineffective as the lubricant was absorbed by the dust and consequently not allow the oil to penetrate the chain links. The customer decided to replace the system with a brush application system, only to find that the dust collected around the brush very quickly, making this system ineffective also. The problem experienced at this tissue converting company was particularly prevalent on a log accumulator where large logs of wound tissue paper collect before being cut to size by high speed log cutters.Improper lubrication led to the chains losing flexibility causing uneven wear of the chains, resulting in the chains, regularly, having to be re- tensioned and chain linkages being replaced this meant machine downtime and loss in productivity. Rotalube Systems improved the lubrication on the log accumulator by installing two unique Rotalube applicators one for each chain on the accumulator. The two applicators were fed lubricant from a pump mounted outside the machine guard. The system delivered fine accurate amounts of oil/air onto the chain link exactly where and when required irrespective of chain speed or stretch.The applicators and system were supplied as a retro fit system, so installation could be done with ease and speed during a Planned shutdown period.When the Rotalube System was installed, the tissue company saw immediate improvements with the chain flexibility, logs running parallel, fewer rejects and less unscheduled maintenance stops.
