Device and method for storing information relating to the operation of a roll or wheel and the obtained roll or the obtained wheel

Abstract

The present invention relates to a roll or a wheel, wherein the roll or the wheel is provided with (i) a stiff, essentially cylindrical roll core or wheel core that Is provided at its lateral surfacewith a surface that is subject to wear; (ii) a data logger, that is positioned on said roll core or said wheel core of said surface, provided with at least (a) a sensor for monitoring information relating to the operation of said roll or said wheel or said surface; (b) a processor for processing said information; (c) tangible, non-volatile memory for storing said information; (d) a wireless network interface for sending and receiving data comprising said information; (e) program data stored in said memory for controlling said processor; (g) a battery or equivalent energy source for feeding (a)and / or (b) and / or (c) and / or (d); wherein said data comprise roll or wheel related data, such as e.g. a unique serial number and / or dimensions for identification of the roll or the wheel.

Description

technical field [0001] The invention relates to rollers, wheels and rollers for handling, processing and / or transporting goods. Background technique [0002] Rollers, wheels and rollers are used in very harsh industrial environments that are subjected to long-term use and are subjected to high loads and tensions. They have different applications in handling, processing and transporting goods. Often the rollers or wheels are part of a larger industrial installation which in many cases comprises a plurality of rollers and / or wheels tuned to each other. [0003] A typical design of a roll starts with a hollow or filled metal core. On the side surfaces of the roll core, a roll surface is applied or not. In one aspect, the roll surface may consist of fouling on the roll core, for example, by depositing a polymer on the roll surface and then "curing" it in an oven. On the other hand, the roll surface can be applied to the roll core as a prefabricated roll cover, for example by...

AI Technical Summary

Problems solved by technology

In this case, the presence of sensors can cause severe local perturbations of the characteristics and even result in perturbed surface profiles

A third disadvantage of the described concept is that it is not specifically designed to measure rotational speed

A fourth disadvantage is the lack of information security; since the information sent by the sending unit is not encrypted, it can be read by every receiver located in the vicinity, even if the receiver is not authorized to do so

A fifth disadvantage is that these sensors cannot be applied under very thin surfaces, such as those made of tungsten carbide with a typical thickness between 100 and 300 μm, or those made of hard chrome layers with lower thicknesses

The sixth disadvantage is that it is also not possible to install rolls or wheels such as those made of steel without any coating, because the sensor interferes with the roll surface

First, the concept lacks autonomy, which can lead to loss of information

Secondly, the proposal is too complex and may lead to disturbed operation, since the integration of sensors in the roll jacket can negatively affect the characteristics of the roll

Third, the concept is not specifically designed to measure rotational speed

Fifth, the physical application of these sensors in specific embodiments is extremely complex and difficult to replicate industrially
