Automatic Description

  • Operators load wheels onto the Wheel conveyor (2) based on the broadcast information provided by the plant.
  • Wheels are transported on Powered Roller conveyor until they come to the Stemming Station. An escapement is provided prior to the Stemmer to ensure only one wheel enters the station each cycle.
  • The wheel enters the Stemmer (4 and 6) where either a standard stem or a TPMS stem is automatically installed in the wheel.
    • The drawing shows two TPMS/Standard Dual Head Stemmers (4 and 6). This is due to the cycle time. The TPMS process takes 14 seconds to complete. Therefore if the production rate is greater than 250 wheels per hour, two units are required.
  • When the wheel is released from the Stemmer, it enters the Tire and Wheel Assembly Machine. At the beginning of the Tire and Wheel Assembly Machine, a TPMS reader (7) is installed to determine if the TPMS sensor is functional and if it is in the proper orientation for mounting. If there is a problem, the wheel is removed prior to the Mounter for repair.
    • This TPMS reader is a GO/NO GO sensor only
    • Wheels that do not pass the GO/ NO GO process can be repaired at the TPMS Repair Bench (1). The location of this bench is independent of the Tireline and can be installed in the location best suited for an operator to do repairs.
  • The wheel is assembled to the tire, matched, inflated and load simulated before exiting the Tire and Wheel Assembly Machine.
  • After the wheel exits the Tire and Wheel Assembly Machine, it passes under the TPMS End of Tireline Reader (13). This reader has some options:
    • Option #1 - GO/NO GO signal to let the process know that the sensor was not damaged during assembly and inflation.
    • Option #2 100% Tire pressure can be monitored. This data can be used for SPC reasons or can be linked back to the inflator to make the inflation process more robust.
  • The tire and Wheel are transported to the Balance Area.

Note: this is one variation of many configurations. Dominion would be happy to assist in the development of specific configurations.
