Conveyor system comprising a friction coefficient measuring device

摘要

In a conveyor system, a conveyor having a conveyor surface transports items. An optional lubricant dispensing device dispenses a lubricant composition on the conveyor surface. A friction coefficient measuring device measures a quantity proportional to the friction coefficient of the conveyor surface and provides a signal indicative for the measured quantity proportional to the friction coefficient. A control receives the signal indicative for the measured quantity. In one embodiment, the control provides a further signal when the measured quantity exceeds a threshold value or for regulating the lubricant amount to be dispensed based on the measured quantity in order to maintain the measured quantity proportional to the friction coefficient within a predetermined range.
