  • Conveyor belt systems have long been used to transfer objects, such as materials, objects, substrates, and workpieces.
  • the transfer belt is suspended between a plurality of rollers, wherein one of the rollers, i.e. a drive roller, is typically connected to a drive mechanism, e.g. a motor, such that rotational movement of the drive mechanism results in rotational movement of the drive roller, which moves the belt with respect to the rollers, providing linear movement.

  • ceramic tiles are arranged upon a conveyor belt, and are moved through a print zone, which typically includes a plurality of print bars, wherein each of the print bar assemblies comprise a plurality of print heads that are arranged to controllably deliver ink onto the tiles as they are moved through the print zone.

  • some recent transfer belts have been manufactured with internal cables, such as comprising metal, e.g. stainless steel, which are required to be accurately welded. While such transfer belt materials may initially have favorable dimensional specifications, e.g. resistance to elongation, the dimensional stability of such belts is often lost during one or more joining processes, e.g. pressing, clamping and/or welding.
  • Enhanced roller registration systems and associated structures provide improved registration for a transfer belt that is driven between rollers. Improved belt materials and construction techniques provide improved dimensional stability over prior transfer belts.
  • one or more sensors provide signals that sense one or more workpieces at one or more locations on the transfer belt. The signals are sent to a controller, which is configured to integrate the detected location of the workpieces with one or more processes that are carried out with respect to the workpieces.

Abstract

On décrit des systèmes améliorés d'alignement de rouleaux et des structures associées, qui assurent un alignement amélioré d'une courroie de transfert menée entre des rouleaux. Des matériels à courroie et techniques de construction améliorés assurent une meilleure stabilité dimensionnelle par rapport à des courroies de transfert de la technique antérieure. Dans certains modes de réalisation des systèmes améliorés d'alignement de rouleaux, un ou plusieurs capteurs émettent des signaux de détection d'une ou de plusieurs pièces à usiner au niveau d'un ou de plusieurs emplacements sur la courroie de transfert. Ces signaux sont envoyés à une unité de commande conçue pour intégrer les informations d'emplacement dans un ou plusieurs processus exécutés en rapport avec les pièces à usiner. Bien que ledit système amélioré d'alignement de rouleaux et lesdites structures puissent être utilisés avantageusement pour une large gamme de convoyeurs, certains modes de réalisation courants sont adaptés à des systèmes d'impression, notamment pour distribuer de l'encre sur des carreaux céramiques.
