In one embodiment, a quick release device (500) coupled to the suction hose dispenser (220), is activated in response to mechanical contact caused by the controllable positioning of the suction hose dispenser (220), said activation facilitating a quick release of the retrieved article to a place (210) associated with an article dispensing area (22).

Abstract: An article dispensing apparatus embodied, for example, as a vending machine, including a controllably positioned suction hose dispenser for retrieving articles from a storage area. In one embodiment, a sensor having an output responsive to changes in partial pressure inside the air hose, such as an airflow sensor coupled to the suction-hose, can initially act to sense the timing of contact of the suction hose with an article to be dispensed. As long as suction is provided to the gripping end of the suction hose prior to the hose contacting the article to be retrieved, the airflow (and partial pressure) inside the hose will change dramatically as the gripping end of the suction hose makes contact with the article. Furthermore, at the moment when the gripping end of the suction hose is no longer in substantial contact with the article, the airflow sensor again provides an indication signal, due to the sudden change in airflow (and partial pressure) that occurs at the time within the hose.
