Definitions

  • the subject matter of the present disclosure broadly relates to the art of tire manufacturing and, more particularly, to tire retreading systems that include reprogrammable RFID tire tracking devices as well as methods of retreading tires that utilize such reprogrammable RFID tire tracking devices.
  • a used tire is typically inspected to identify areas in need of repair and any foreign objects that may be embedded with the tire tread layer and/or tire casing. Once the inspection is complete, the used tire has the worn tread layer removed, such as by way of a grinding or abrading process that is sometimes referred to as “buffing”. The resulting tread-free tire casing can then be repaired and/or reconditioned, such as to repair small holes and/or remove foreign objects, for example. Thereafter, a new layer of uncured or “green” tread rubber is applied around the tire casing in place of the original, worn tread layer.
  • the retreaded tire assembly undergoes a curing process in which the layer of uncured tread material is vulcanized or otherwise cured as well as permanently bonded to the tire casing to form a completed retread tire.
  • used tires are commonly received at retreading facilities together with instructions and/or specifications from the tire owner to be used during the retreading process. For example, certain tire owners may select specific details and/or performance characteristics for the finished retread tire. Additionally, or in the alternative, information relating to areas of a given used tire identified as needing repair and/or internal specifications particular to processing used tires of a specific type, construction and/or size can also be associated with specific tires undergoing a retreading process. As such, it is typical for certain information and/or details specific to a given used tire to follow that particular tire through the retreading process. In conventional processes, identifying information is typically applied on or along an outer sidewall of each tire being processed. For example, in some cases, identifying information is applied by manually marking the identifying information on the tire sidewall with a writing instrument. In other cases, identifying information can be applied by attaching a label to the outer sidewall of the tire.
  • identifying information can, in some cases, become visually unreadable as the used tire or tire casing thereof is transported through the processing facility and/or handled during individual processing operations, such as by being visually obscured by extraneous material and/or by being partially removed (e.g., smudged, scraped), for example.
  • the retreading system can be operable to process an associated pneumatic tire casing that includes an associated tire cavity and an associated magnetic layer.
  • the retreading system can include a processing system that includes a system processor and a system memory communicatively coupled with the system processor.

Abstract

Des systèmes de rechapage de pneu peuvent être utilisés pour traiter des enveloppes de pneumatique qui comprennent une cavité de pneu et une couche magnétique incorporée dans cette dernière. Des dispositifs de suivi RFID reprogrammables comprennent une base magnétique et une antenne radiofréquence ainsi qu'une mémoire de dispositif utilisable pour stocker des enregistrements de données et un processeur de dispositif. Une station de rechapage comprend un dispositif de communication radiofréquence couplé en communication à un système de traitement. Le dispositif de communication radiofréquence est utilisable pour communiquer des enregistrements de données présentant une relation avec les enveloppes de pneu et/ou la performance de processus de rechapage sur l'enveloppe de pneu vers et/ou à partir du dispositif de suivi RFID reprogrammable tandis que le dispositif de suivi RFID reprogrammable est positionné à l'intérieur de la cavité de pneu et fixé à l'enveloppe de pneu par attraction magnétique vers la couche magnétique. L'invention concerne également des procédés de rechapage de pneus comprenant de tels dispositifs de suivi RFID reprogrammables.
