Patent

CA 2323480

A labeler for objects, such as fruit or vegetables, has a pickup head that includes a firing piston, and a larger piston that is coupled to the firing piston. The pickup head, along with other pickup heads, are provided on an assembly that rotates the heads in a circular manner. When each pickup head is at the 6 o'clock position, a burst of air pressure is provided to the firing piston, thereby causing it to fire and to cause the larger piston to move in an outward direction. This causes the pickup head to extend fully, to thereby cause a label positioned on an applicator at a distal end of the pickup head to contact an object and thereby apply the label to the object. At other positions besides the 6 o'clock position, a vacuum source provides a vacuum to the pickup heads, thereby maintaining the pickup heads in a fully retracted position, as well as providing a way for keeping the label on the applicator of the pickup head while the pickup head is rotating.

L'invention porte sur un étiqueteur d'objets tels que des fruits ou légumes comportant une tête collectrice comportant un piston percuteur et un piston plus gros lui étant couplé. La tête ainsi que d'autres têtes sont montées sur un élément leur imprimant un mouvement tournant. Lorsqu'une tête arrive à la position "6 heures" le piston percuteur reçoit une décharge d'air comprimé qui le lance et entraîne le gros piston vers l'extérieur. Cela provoque le déploiement intégral de la tête collectrice qui entraîne une étiquette déposée sur un applicateur lui-même placé à l'extrémité distale de la tête collectrice venant au contact d'un objet. Dans les positions autres que "6 heures", les têtes sont soumises à une dépression qui les maintient en position rétractée, tout en maintenant l'étiquette sur l'applicateur de la tête pendant sa rotation.
