Publication number: 20230125161Abstract: An electrically operated pumping assembly for a plural component spray system includes an electric motor (14) having a stator (88) and a rotor (90). The rotor is disposed coaxially with first and second pumps (26a, 26b) and is configured to cause pumping by each of the first and second pumps. The first and second pumps are configured to pump different component materials to an applicator (34) for forming a plural component spray material. A drive mechanism (86) is disposed between and connected to each of the rotor and the fluid displacement members (70a, 70b) of the first and second pumps.

Patent number: 10632494Abstract: An adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas provided to the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller is in electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.Type: GrantFiled: February 21, 2018Date of Patent: April 28, 2020Assignee: Graco Minnesota Inc.Inventors: Robert J.

Patent number: 10555905Abstract: A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.Type: GrantFiled: March 22, 2019Date of Patent: February 11, 2020Assignee: Graco Minnesota Inc.Inventors: Paul R. Quam, Matthew R. Theisen, Parker J. Haffley

Patent number: 9884331Abstract: A bellow seal of a fluid dispensing system is disclosed. The bellow seal having a generally circular cross section includes a first end having a first diameter. The bellow seal further includes a second end having a second diameter that is smaller than the first diameter of the first end. The bellow seal further includes a contoured external surface extending between the first end and the second end. The external surface includes a cylindrical portion extending from the first end, an undulating portion, (which includes a convex portion extending from the cylindrical portion and a concave portion extending from the convex portion), and a tapered portion extending from the concave portion to the second end. The bellow seal further includes a flexible region defined between a first point located on the cylindrical portion and a second point located on the concave portion.Type: GrantFiled: October 29, 2015Date of Patent: February 6, 2018Assignee: Graco Minnesota Inc.Inventors: Parker J.

Publication number: 20130112073Abstract: Enclosure (16) for housing a coupler (18) between a driving rod (20) and a driven rod (22) comprises a first and a second preferably cylindrical pieces (30, 28). Said pieces are sized so that the first piece (30) is able to slide telescopically within the second piece (28) and are threaded to engage each other when in operation the enclosure (16) is in a close position, thereby the enclosure (16) being able to retain lubricant in the inside. For service, after having drained the lubricant from the enclosure (16), the two pieces are loosened by screwing the first piece (30) until the end of the thread is reached, and then the first piece (30) is slideably telescoped into the second piece (28), thereby setting the enclosure (16) in an open position an enabling easy access to the rod coupler (18).Type: ApplicationFiled: November 19, 2010Publication date: May 9, 2013Inventors: Nicholas K.
