Problems solved by technology
While the actual friction, or coefficient of friction, between the item and the conveyor in this system is measured based on instantaneous operating conditions and used to apply the desired amount of lubricant to the conveyor surface, the small housing that keeps the measurement item The use significantly interferes with the "normal" transport of items on the conveyor along the conveyor path, which results in a reduction in throughput time
Also, it has been found in practice, however, that the measurements are based on instantaneous operating conditions in some cases, for example, where bottles transported on conveyors can tip over and cannot even overcome small inclinations

Embodiment Construction
[0075] Note that the invention will be described with reference to the example of a conveyor and a lubrication system, but it is to be noted that the invention can also be used in a conveyor system without a lubricant spreading device. In such a conveyor system, the control means are arranged for providing a further signal dependent on a signal representing the measured quantity proportional to the coefficient of friction provided by the friction measuring device. When the measured quantity, which is proportional to the coefficient of friction, exceeds a threshold value, a further signal is generated by the control device, which can be used, for example, as an indication that the conveyor surface needs to be cleaned.
[0076] exist figure 1 An embodiment of a conveyor and lubrication system according to the invention is schematically shown in . The system 1 comprises an endless conveyor 2 having an upper conveyor surface 3 on which items 4, in this example bottles, are transp...

In a conveyor system a conveyor (2) having a conveyor surface (3) transports items. An optional lubricant dispensing device (5) dispenses a lubricant composition on the conveyor surface. A friction coefficient measuring device (6) measures a quantity proportional to the friction coefficient of said conveyor surface and provides a signal indicative for said measured quantity proportional to the friction coefficient. The friction coefficient measuring device comprises a contact portion (11) for contacting the conveyor surface. A control means (7) receives the signal indicative for said measured quantity. The control means can be arranged for providing a further signal when said 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. The measuring device comprises a replacement device for automatically replacing the contact portion of the friction coefficient measuring device.
