Title
(EN) APPARATUS FOR CONTROLLING THERMAL TRANSFER RIBBON
(FR) APPAREIL DE COMMANDE D'UN RUBAN DE TRANSFERT THERMIQUE
Abstract
(EN)
An apparatus for use in a thermal printer for printing bar code symbols onto a paper substrate material is provided which utilizes a ribbon (5) having a multi-transfer ink layer. The thermal printer enables the ink ribbon (5) to be transported at a rate that is selectively lower than the transporting rate of the paper substrate (7). The thermal printer comprises a platen (20) and a thermal head (32) disposed adjacent to the platen (20) having a region defined therebetween through which the paper substrate material (7) is transported at a first rate. Images or symbols are imprinted onto the paper substrate material (7) by operation of the thermal head (32) in cooperation with ink from the multi-transfer ink ribbon (5) advanced to the region. A supply hub (42) carries a supply of the ribbon (5), and a first motor (10) is mechanically linked to the supply hub (42). The first motor (60) rotates the hub (42) in a direction opposite to a direction of advancement of the ribbon (5). A roller (46) is mechanically linked to the first motor (60) and has a surface engaging the ribbon provided with a friction coefficient sufficient to prevent slippage of the ribbon (5) across the surface. A second motor (70) applies a tension on the ribbon, and a clutch interposed between the first motor (60) and the supply hub (42) permits controlled slippage of the supply hub (42) to permit advancement of the ribbon. A take-up hub (44) mechanically linked to the second motor (70) receives the ribbon (5) after its passage through the region between the platen (20) and the thermal head (32).

Appareil annexe d'une imprimante thermique de codes-barres sur un substrat de papier utilisant un ruban (5) à couche d'encre multitransfert. L'imprimante thermique assure le transport du ruban (5) à une vitesse sélectionnable moindre que celle du papier. Elle comporte une platine (20) et une tête thermique (32) contiguë à la platine (20) et une zone les séparant à travers laquelle le substrat de papier se déplace à une première vitesse. L'impression sur le substrat se fait au moyen de la tête thermique (32) et du ruban encreur (5) qui pénètre dans cette zone. Une bobine d'alimentation (42) à laquelle est couplé un premier moteur (60) contient une réserve de ruban. Ledit moteur fait tourner la bobine dans un sens opposé à l'avance du ruban (5). Un rouleau relié mécaniquement audit moteur (60) présente une surface de contact avec le ruban dont le coefficient de frottement est suffisant pour empêcher le glissement du ruban. Un deuxième moteur exerce une tension sur le ruban et un embrayage placé entre le premier moteur (60) et la bobine (42) provoque un glissement contrôlé de la bobine (42) permettant l'avancement du ruban. Une bobine réceptrice(44) couplée au deuxième moteur récupère le ruban (5) après son passage dans la zone séparant la platine (20) de la tête thermique (32).
