  • Publication number: 20230347611
    Abstract: A dual tire buffing apparatus includes a turntable having a first end and an opposite second end. The turntable is rotatable about a central axis between first and second positions. A first expandable hub is rotatably coupled to the turntable proximate the first end. The first expandable hub is configured to receive a first tire casing. A second expandable hub is rotatably coupled to the turntable proximate the second end. The second expandable hub is configured to receive a second tire casing. A rasp head is positioned to operatively engage the first tire casing on the first expandable hub when the turntable is in the first position to perform a buffing operation on the first tire casing, and to operatively engage the second tire casing on the second expandable hub when the turntable is in the second position to perform a buffing operation on the second tire casing.

  • Patent number: 10213975
    Abstract: A loader device includes a support pedestal movable over a range of longitudinal travel along a longitudinal axis, a support carriage movably mounted to the support pedestal, a loader actuator, and a dismount actuator. The support carriage is movable over a range of vertical travel along a normal axis, which is perpendicular to the longitudinal axis. The support carriage has a support arm adapted to support a tire casing. The loader actuator and dismount actuator are respectively adapted to selectively move: (1) at least a portion of a tire casing supported upon the support carriage in a loading direction along the longitudinal axis off of the support arm onto the expandable rim hub and (2) at least a portion of a tire casing supported upon the expandable rim hub in an opposing unloading direction off of the expandable rim hub and onto the support arm of the loader device.

  • Publication number: 20170176175
    Abstract: Systems and methods of identifying and buffing tire casings are provided. A tire buffing machine includes an expandable rim, a buffer, a measurement sensor configured to generate measurement data, and a controller. The controller maintains a database of a plurality of casing profiles, where each casing profile includes known casing measurements and corresponding buffing parameters. The controller receives measurement data from the measurement sensor, identifies the casing mounted onto the expandable rim, and operates the buffer to buff the casing in accordance with buffing parameters in the matching casing profile.

  • Patent number: 8813550
    Abstract: A tire inspection machine includes an incoming conveyor adapted to transport tires to the machine and also align the tires in a transverse direction. An inspection table of the machine includes a table conveyor system that is responsive to a controller. The table and table conveyor are together arranged to permit scanning of both sidewall portions of a tire disposed thereon. A sensor detects a longitudinal position of the tire and stops the table conveyor when the tire is longitudinally aligned. A controller operates the table conveyor based on the longitudinal position of the tire.

  • Patent number: 8662134
    Abstract: A system and method for removing an outer layer of resilient material from an object to achieve a target outer dimension includes performing an initial cut at a cutting depth to remove an outer layer of the material. A parameter indicative of a work input to a cutter that performed the cut is acquired and used to determine the cutting depth that will be used for performing a subsequent cut to remove an additional layer. In this way, subsequent cuts are performed until the target outer dimension is achieved.
