Abstract
A method and system are provided for performing vend operations on articles selected by a purchaser. Articles to be dispensed are stored in a storage section, and purchased articles are transferred from the storage section to a vend section. A vend mechanism is provided for rapidly moving a given article from a vend-destined section to the vend section. A helical transfer member holds the articles in the storage section and is rotatable in a dispensing direction to transfer the given article from a position adjacent the vend-destined section to the vend-destined section. The helical transfer member is also rotatable in a reverse direction opposite the dispensing direction. A driver is coupled to each helical transfer member, and is actuable to rotate the helical transfer member in either the dispensing direction or the reverse direction. A controller is operable during each vend operation to control the driver to first rotate the helical transfer member in the dispensing direction by a first amount until the given article is fully transferred to the vend-destined section. The controller then controls the driver to then rotate the helical transfer member in the reverse direction by a second amount until an article immediately following the given article is securely held in the storage section.
