Patent number: 7556140Abstract: A bulk material handling accessory such as a conveyor belt cleaner for use in connection with a bulk material handling system. The bulk material handling accessory includes a main frame, a scraping member including an arm and a scraper blade pivotally attached to the main frame, and a damper mechanism coupled at one end to the main frame and at another end to the scraping member. A mounting mechanism is attached to the main frame for providing linear and rotational movement of the main frame and the associated scraping member and damper mechanism. The damper mechanism includes a damper having a piston and a housing having a fluid chamber. The viscosity of the fluid within the fluid chamber is selectively changeable to change the damping characteristics of the damper mechanism to accommodate changes in operating conditions.Type: GrantFiled: August 15, 2007Date of Patent: July 7, 2009Assignee: Martin Engineering CompanyInventors: R. Todd Swinderman, Cristian Vava

Patent number: 7549532Abstract: A wiper blade for removing material from a conveyor belt attached to the conveyor belt frame near the nose roller such that the belt will not have material on the belt during the return portion of the loop. The wiper blade is easily attached to and removed from the conveyor frame for installing and replacing the wiper blades when they become worn. The wiper blade is slid out from its slot on the support bar and a new blade inserted into the slot and slid into a locking position for a quick and low cost change of blades. The support bar is rotatably attached to the conveyor frame to adjust the edge of the wiper blade to be proximate the conveyor belt. The wiper blade is made of an elastomeric material without any metal parts for ease of recycling.Type: GrantFiled: July 17, 2007Date of Patent: June 23, 2009Assignees: Nelson Williams Linings, Inc.Inventor: Arthur C. Ostman

Publication number: 20090133990Abstract: A secondary system for cleaning a belt running between conveyor pulleys. The secondary system is comprised of a frame bar on which cleaning blades are mounted, two bracket assemblies to which the frame bar is adjustably mounted and an adjustment system mounted on the external sides of the bracket assemblies. In one embodiment, the bracket assemblies each include a pair of slotted arms over which two or more clamps are joined together. In another embodiment, each bracket assembly is comprised of an inner tube member that telescopes into two outer tube members, i.e., and an upper member that can be adjustably clamped to the inner tube and a lower tube member to which the frame bar is mounted and that is attached to said upper member by the adjustment system. The frame bar and bracket assemblies have rectangular cross-section so that, when mounted to each other, rotational movement of frame bar about its longitudinal axis is prohibited.Type: ApplicationFiled: October 9, 2008Publication date: May 28, 2009Inventor: William Metzner

Patent number: 7516837Abstract: An ink-jet recording apparatus has rollers, a conveyor belt, a conveyor belt driving mechanism, an ink-jet head, an absorber, a scraper, a supplier, and a supply controller. The conveyor belt spans the rollers. The driving mechanism rotates the rollers to move a record medium disposed on one surface of the conveyor belt in a predetermined conveyance direction. The absorber absorbs cleaning fluid and contacts and applies the cleaning fluid to the one surface of the conveyor belt. The scraper comes into contact with the one surface of the conveyor belt and scrapes the cleaning fluid attached to the one surface. The supplier supplies cleaning fluid to the absorber. The supply controller controls a supply of cleaning fluid from the supplier to the absorber, so that the supply controller makes the supplier supply cleaning fluid to the absorber in response to a print command, for a first period of time before the driving mechanism rotates the rollers to make the conveyor belt start traveling.Type: GrantFiled: March 17, 2006Date of Patent: April 14, 2009Assignee: Brother Kogyo Kabushiki KaishaInventors: Hideaki Teshima, Atsuhisa Nakashima

Publication number: 20090032371Abstract: A wiper for a conveyor belt (8) is described having a rubber-elastic wiper strip (4) replaceably inserted into a retainer (3) and possibly assembled from individual strip sections arrayed adjacent to one another, which forms a wiper edge (6) between a rear (9) facing away from the conveyor belt (8) and a flank (10) facing toward the conveyor belt (8) and running out into a free surface (11), and which tapers toward the front ends starting from a central longitudinal section. To lengthen the service life of the wiper strip, it is suggested that the wiper strip (4) be tapered by a flank setback (12) in a wear area adjoining the free surface (11).Type: ApplicationFiled: July 29, 2008Publication date: February 5, 2009Inventor: Peter Hoessl

Patent number: 7472784Abstract: A conveyor belt cleaner scraper blade for cleaning the surface of a conveyor belt and a method of manufacture of the scraper blade. The scraper blade includes a body having a base member adapted to be attached to a cross shaft of a conveyor belt cleaner and a scraping member which extends outwardly from the base member to a scraping tip. The scraper blade includes one or more electrical sensors that are embedded in an insert member. The insert member and the sensors are molded and embedded within the body of the scraper blade. Each of the sensors is adapted to provide an electrical output signal representing a physical condition of the scraper blade sensed by the sensor. A variety of sensor embodiments are described, as well as two embodiments of control and monitoring systems for use in conjunction with the various blade and sensor combinations.Type: GrantFiled: September 27, 2006Date of Patent: January 6, 2009Assignee: Martin Engineering CompanyInventors: R.

Patent number: RE42844Abstract: A pump for transporting particulate material includes an inlet, an outlet, a passageway, a first and second load beam, a first and second scraper seal, and a first and second drive assembly. The inlet introduces the particulate material into the passageway and the outlet expels the particulate material from the passageway. The passageway is defined by a first belt assembly and a second belt assembly that are opposed to each other. The first and second load beams are positioned within the first belt assembly and the second belt assembly, respectively. The first scraper seal and a second scraper seal are positioned proximate the passageway and the outlet. The first drive assembly is positioned within an interior section of the first belt assembly and drives the first belt assembly and the second drive assembly is positioned within an interior section of the second belt assembly and drives the second belt assembly.Type: GrantFiled: December 1, 2008Date of Patent: October 18, 2011Assignee: Pratt & Whitney Rocketdyne, Inc.Inventors: Kenneth M. Sprouse, David R. Matthews
