  • Patent number: 11536647
    Abstract: A measurement system and a method for measuring a coefficient of friction on a slidable conveyor belt in a direction of movement are provided. The system includes a disk floatingly placed on the conveyor belt and having a bottom surface, wherefrom projects at least one rounded element that rests on the conveyor belt, having a shape that, regardless of the relative orientation of the disk and the conveyor belt, at least one rounded element extends along a direction not parallel to the direction of movement, a pair of abutment elements maintaining the disk fixed with respect to the direction of movement of the conveyor belt, and a pair of load cells operatively associated with the abutment elements and with the disk, to measure a thrust force exerted by the disk on each load cell by effect of the relative sliding of the conveyor belt with respect to the disk.

  • Patent number: 9415943
    Abstract: Various embodiments of conveyor system devices, such as sprockets and idlers, are disclosed. The conveyor components can comprise axial and/or radial openings that facilitate the discharging of debris and other contaminants, which can reduce wear and/or prolong component life. In some embodiments, the conveyor component ramps convey the debris and contaminants to the openings.

  • Publication number: 20120061213
    Abstract: Module, for conveyor presenting connected modules, having upper and lower surfaces, two lateral walls, front and opposing rear walls and, projecting from front wall and rear wall module connecting elements. Connection elements each comb shaped, so one module's elements insertable between next or preceding module elements, and having through holes mutually coaxial for receiving transverse pin for removably connecting at least two modules. Each module has element blocking pin longitudinal movements including locking element removably insertable into seat in module. Seat communicates with through holes and extends from module upper to lower surface. In positions corresponding with each surface an aperture for inserting or removing locking element into or from seat. Locking element elastically deformable portion, only if deformed, enabling inserting and snap-retaining locking element in seat, preventing pin longitudinal movements.

  • Publication number: 20120061209
    Abstract: A module for forming a conveyor, particularly a band conveyor, presenting a plurality of modules connected together, each module including: an upper surface, a lower surface, conventional elements for removably connecting the modules together to form the conveyor, and connection element for removably connecting additional members, particularly a thrust bar, to the upper surface; in which the connection element includes, on the exposed face of the upper surface of the module, at least one predefined identification mark, the module presenting, below the upper surface in a position corresponding with the at least one predefined mark, at least one connection element extending from and closed by the upper surface and provided with, or in which there can be provided, a seat or hole adapted to cooperate with means, to removably connect the additional member to the upper surface of the module.
