Patent number: 9984551Abstract: A system for anticipating low-speed bearing failure triggers a notification when a noise generated by the low-speed bearing exceeds a threshold. The system predicts failure far in advance of the actual failure. The system includes an accelerometer for detecting the noise generated by the bearing. The signal produced by the accelerometer is processed using a band pass filter, an amplifier/rectifier, an averaging filter, and a voltage to current converter. The signal and raw data are transmitted to a remote monitoring system, such as a computer. The signal is further analyzed, such as to produce a best-fit line. When the signal exceeds a predetermined threshold, such as when the amount or the slope of the best-fit line exceeds a value, the remote system notifies a monitor to schedule maintenance.Type: GrantFiled: March 15, 2016Date of Patent: May 29, 2018Assignee: Ashworth Bros., Inc.Inventors: Joseph M.

Patent number: 9908654Abstract: An apparatus for storing, transporting and dispensing conveyor belts is described. The apparatus, in the form of a crate, has top and bottom conventional pallets, allowing for easy handling and strength for additional stacked crates. The center of the crate holds a hub assembly that moves rotationally, and allows smooth transition from consecutive layers of the conveyor belt wrapped thereon. During shipment, the roll of conveyor belt lies on its side. In one embodiment, a center pipe axle of the spool passes through holes in the top and bottom pallets. Alternatively, the center pipe axle passes through channels created between planks of the top and bottom pallets. These configurations secure the roll in the crate, and allow it to turn freely when loaded or unloaded.Type: GrantFiled: May 28, 2013Date of Patent: March 6, 2018Assignee: ASHWORTH BROS., INC.Inventors: Paul Steinhoff, Joseph Allen Bowen, Darroll Joseph Neely

Patent number: 9157160Abstract: An electropolishing or electroplating system and method for metal conveyor belts is described. As opposed to conventional polishing processes in which the product is guided around rollers which direct the product into and out of an electrolyte bath, embodiments of the present invention pass the product through a housing supplied with a continuous directional flow of electrolyte. Thus, the electroplating or electropolishing can be targeted to specific areas of the product, such as the edges and/or the center of a conveyor belt, and straight products can pass through the housing without deformation.Type: GrantFiled: August 22, 2013Date of Patent: October 13, 2015Assignee: ASHWORTH BROS., INC.Inventors: Matthew James Kovalchick, Jay F.

Patent number: 8857608Abstract: A link member having a replaceable wear component and a conveyor belt comprising a link member having a replaceable wear component are described. One aspect of the present invention provides a sacrificial or replaceable wear component that is attached to a conveyor belt. The conveyor belt can be any type of conveyor belt, such as a grid-type or flat-wire conveyor belt. The wear component is attached by mechanical or other means to allow its removal after a certain wear limit has been achieved. A new component can be installed to bring the conveyor belt to nearly new condition. This will extend belt life because only the wear component needs to be replaced, rather than the entire belt.Type: GrantFiled: July 31, 2012Date of Patent: October 14, 2014Assignee: Ashworth Bros., IncInventors: Joseph M.
