Patent number: 9731566Abstract: A tire changer with a controller includes a with a mount assembly adapted for contacting a wheel assembly to mount the wheel to a rotating spindle. The tire changer controller is configured to regulate the operation of a motor, and which is operatively connected to the rotating spindle to rotate the wheel assembly. A sensor coupled to the controller provides a data representative of the rotational position of the wheel assembly about a rotational axis. The controller is further configured to engage a load roller with the wheel assembly to apply a radial force to a tire mounted on a rim of the wheel assembly during rotation of the wheel, and to regulate the operation of a tire handling means and mount assembly, enabling identification, optional marking, and adjustment of the tire angular mounting position relative to the wheel rim.Type: GrantFiled: November 3, 2014Date of Patent: August 15, 2017Assignee: Hunter Engineering CompanyInventors: David A. Voeller, Douglas S. Hanneken, Steve Molbach, Joel Clasquin, Michael D. Gerdes

Patent number: 9283820Abstract: A center clamping mechanism for a wheel assembly service machine such as a tire changer machine includes a back cone centering element projecting outwardly from a platen and configured to engage a center bore of the wheel rim hub mount pad from an inner side of the hub mount pad. The centering element may include a compliant element configured to at least partially support the weight of the wheel rim and tire when being clamped. A pivot arm defines a contact surface for the inner side of the wheel rim hub mount pad, and when the tire is rotated by an operator with the inner side in contact with the contact surface, an anti-rotate pin carried on the pivot arm may be adjusted in radial position relative to the drive axis to accommodate different lug holes at varying lug bolt circle diameters.Type: GrantFiled: April 19, 2012Date of Patent: March 15, 2016Assignee: Hunter Engineering CompanyInventor: Douglas S. Hanneken

Patent number: 9073394Abstract: Tire changing machines including force and position sensors facilitating automated detection of wheel rim and tire features by a controller. Dimensional and location information for features of interest may be detected and recorded for use by the controller to perform tire change procedures. Positioning error and malfunctioning machine components, including feedback sensors, may also be detected in an automated manner.Type: GrantFiled: March 13, 2013Date of Patent: July 7, 2015Assignee: HUNTER ENGINEERING COMPANYInventors: Joel Clasquin, Steven K. Molbach, Douglas S. Hanneken, Charles Polster

Patent number: 8985178Abstract: Automated tire changer machines, control systems and methods therefor utilize positive contact and contact force generation between wheel rims and bead breaker devices to break tire bead seals. The bead breaker devices may accordingly follow different geometries of wheel rims without prior knowledge or identification of the specific rim configuration by the machine.Type: GrantFiled: April 20, 2011Date of Patent: March 24, 2015Assignee: Hunter Engineering CompanyInventors: Micah N. Vaninger, Douglas S. Hanneken, Charlie Polster, Joel Clasquin, Steven K. Molbach

Patent number: 8973640Abstract: A tire changer machine and tire demounting methodology includes a demount tool assembly having a demount tool selectively positionable relative to a support and configured to extract a bead of the tire from the wheel rim. A guide element is mounted to the support, and the guide element is operable to provide a limited degree of freedom of the distal end from a predetermined path of motion in a tire demount procedure, thereby allowing the distal end to reliably grip the tire bead while the support arm is maintained in a stationary position relative to the wheel rim.Type: GrantFiled: December 6, 2011Date of Patent: March 10, 2015Assignee: Hunter Engineering CompanyInventor: Douglas S. Hanneken

Patent number: 8770254Abstract: A tire changer machine includes a control system that monitors a rotational position of a sensitive feature associated with a wheel rim and tire during a tire change procedure. The system adjusts operation of the machine to avoid damaging the sensitive feature, which may be a valve stem or a wheel sensor such as a tire pressure monitoring system (TPMS) sensor.Type: GrantFiled: October 26, 2010Date of Patent: July 8, 2014Assignee: Hunter Engineering CompanyInventors: Douglas S. Hanneken, Micah N. Vaninger, Steven K. Molbach, Joel Clasquin

Patent number: 8613303Abstract: Tire changing machines having force feedback and position control systems are described that may be used to control operation of one or more components of the machine during a tire change procedure. Information may be provided to a machine operator concerning detected operating conditions during the procedure. Excessive or abnormal forces or component positions can be detected and corrective action may be taken at any point in the tire change procedure. Successful component position profiles may be saved for future recall and execution by the machine.Type: GrantFiled: July 16, 2009Date of Patent: December 24, 2013Assignee: Hunter Engineering CompanyInventors: Douglas S. Hanneken, David A. Voeller, Charlie Polster, Joel Clasquin, Michael D. Gerdes, Nicolas J. Colarelli, III

Patent number: 6651306Abstract: A truss manufacturing apparatus and method. The apparatus includes a conveyor for moving upper and lower chords thru a series of assembly stations of the apparatus. A board is inserted between the chords at one station and secured in place forming a trimmable end of a truss. One or more web boards can be inserted between the chords at a second station and secured in place by connector nail plates forming a opening in the truss for ductwork or the like. Metal web members are secured to opposite side edges of the truss at a third station to form a web between the chords. The chords are positioned in a generally vertical plane with one above the other in the apparatus and the board, web boards and web members are moved into position from one or both sides of the chords.Type: GrantFiled: June 16, 2000Date of Patent: November 25, 2003Assignee: MiTek Holdings, Inc.Inventors: Robert A.
