Publication number: 20040182681Abstract: A low pressure blower operated airknife having a housing with an elongated primary air discharge orifice for directing a narrow width curtain of air. The airknife includes an air-augmenting shroud which defines auxiliary discharge orifices on opposite longitudinal sides of the primary air discharge orifice such that air discharging from the primary discharge orifice creates a low pressure condition adjacent the auxiliary air discharge orifices for drawing additional air through the auxiliary discharge orifices which augments the velocity and volume of the discharging air current without the necessity for increasing the air inlet pressure or blower size. The shroud may take alternative forms, including pairs of wings disposed on opposite sides of the primary discharge orifice or hollow structures that surround the airknife housing. The airknife further is adapted for low pressure direction and application of air laden particles, such as preatomized liquid particles.Type: ApplicationFiled: January 27, 2004Publication date: September 23, 2004Applicant: Spraying Systems Co.Inventors: James Haruch, Wai Y.

Patent number: 6766895Abstract: In a work conveying system including at least a work holder for holding a work and a horizontal mover for moving the work holder horizontally in an upper ceiling space within a clean room, the work being conveyed to each of plural processing apparatuses. The horizontal mover has at least one linear moving mechanism including a duct with an internal guide, a traveling body engaging the guide and traveling through the traveling path defined by the duct, and a slider connected to the traveling body for travel with the traveling body on the exterior of the traveling path. The work holder is attached to the slider. Air cleaners are disposed at suitable intervals in the traveling path to clean the air therein and to discharge the cleaned air to the exterior. The traveling path accommodates a drive source, a drive mechanism, and a power supply.Type: GrantFiled: August 29, 2002Date of Patent: July 27, 2004Assignee: Hirata CorporationInventor: Kazuyuki Matsumura

Patent number: 6740172Abstract: A modular conveyor belt passes over and around at least one sprocket carried on a non-rotating hollow shaft and causes rotation of the sprocket. The sprocket includes a first pair of diametrically opposed sectors and a second pair of diametrically opposed sectors that are laterally staggered in relation to the first pair of sectors. Each sprocket is flanked by a pair of nozzles, each of which produces a fan-shaped spray. The fan-shaped sprays overlap one another across the lateral extent of the belt so that the entire breadth of the belt is cleaned. Adjacent fan-shaped sprays are angled relative to one another so that their respective sprays do not interfere with one another. The staggered sector design ensures that all sections of the belt are exposed to the spray. The nozzles are positioned to clean hinges of the belt when the hinges are open.Type: GrantFiled: November 21, 2002Date of Patent: May 25, 2004Inventors: Terry Cemlyn Griffiths, Braiden Thomas Griffiths

Patent number: 6732854Abstract: A bristle cleaner station for a conveyorized sheet material cutting machine includes a plurality of air jets that direct pressurized air between downwardly extending bristles of a bristle bed to dislodge debris; and a vacuum chamber adjacent to the bristles to draw away the dislodged debris. The preferred embodiment uses air needles that extend into downward extending bristles to riffle or bend the bristles, making an enlarged space between them. The air needles direct pressurized air into the enlarged space to dislodge debris, and an upwardly open vacuum channel adjacent to the air needles and bristles collects the dislodged debris. A method to clean bristle beds is also disclosed whereby pressurized air is directed between the bristles and vacuum draws away dislodged debris.Type: GrantFiled: November 15, 2001Date of Patent: May 11, 2004Assignee: Gerber Technology, Inc.Inventors: Richard Kuchta, Tim Vander Vos, Steve Venditti, Joseph Vivirito, John Genereux

Patent number: 6695122Abstract: A chip conveyer including an endless conveying member (18) that circulates in a predetermined direction for receiving chips discharged from a machine tool in a receiving zone, conveying the chips to a discharge position (E2) spaced from the receiving zone at a predetermined interval, and discharging the chips at the discharge position. A conveying member (18) travels along a forward route (R2) from an end (E1) of the receiving zone to a turning point (E2) of the conveying member (18), discharges the chips at the turning point (E2), and travels along a return route (R3) from the turning point (E2) to a return point (E3) where the conveying member (18) is returned to the receiving zone. The conveying member (18) enters the liquid reservoir (31) while moving along the return route (R3) such that the chips adhered to the conveying member due to an oil component are separated in liquid in the liquid reservoir (31). A liquid supply device supplies the liquid to the liquid reservoir (31).Type: GrantFiled: March 14, 2002Date of Patent: February 24, 2004Assignee: Enomoto Industry Company, Ltd.Inventor: Yukio Enomoto

Publication number: 20040026213Abstract: A cleaning system for a particulate material conveyor comprises a sprocket (22) having one or more radial through-channels (25a, 25b, 25c). This or these channels connect with an inlet for a cleaning fluid supply and each has one or more fluid outlets exiting from the surface of the sprocket, whereby when the sprocket rotates, fluid provided through the inlet is distributed through the radial channel and out of the fluid outlets. The fluid is dispersed in a turbulent manner about the cavity (29) surrounding the sprocket.Type: ApplicationFiled: June 24, 2003Publication date: February 12, 2004Inventor: Andrew John Blue

Publication number: 20040020748Abstract: A self-cleaning oscillating conveyor includes a vertical tube and a conveyor channel that is helically wound upwardly around the vertical tube with a corresponding electromagnetic oscillating unit and a casing tube, which surrounds the exterior of the conveyor channel. The chamber between the vertical tube and the casing tube can be sprayed by several nozzles, which penetrate the interior of the vertical tube, or the exterior of the casing tube, with a liquid detergent, sprayed under pressure and using a delivery pump. The cleaning liquid runs onto the collection plate and over the rim thereof into a collection channel having a drain. In a preferred embodiment, semi-tubes, or half-tubes, are longitudinally mounted onto the casing tube in a sealed manner and a row of nozzles penetrates the casing tube from the chamber between the interior of the semi-tubes and the casing tube towards the interior.Type: ApplicationFiled: May 7, 2003Publication date: February 5, 2004Inventor: Paul Kramer

Patent number: RE39186Abstract: A sprocket for an endless conveyor is disclosed having a plurality of fluid outlet passages arranged radially between the center of the sprocket and its outer circumferential surface. The outlet passages are positioned along the length of the sprocket in a helical path and are in fluid communication with an annular fluid conduit extending lengthwise along the center of the sprocket. A fluid inlet connected to the conduit supplies fluid under pressure to the conduit, the fluid spraying radially outwardly through the outlet passages to impinge on the inside surface of the endless conveyor and remove any accumulated debris. Nozzles are positioned within the outlet passages to control the fluid spray.Type: GrantFiled: April 8, 2004Date of Patent: July 18, 2006Inventor: Preston D. Montgomery
