DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a commodity takeout unit of an automatic vending machine used to vend a commodity finished by cramming contents into a vessel such as a bottle, can, or PET bottle.
BACKGROUND ART
An example of this type of the commodity takeout unit of an automatic vending machine is disclosed in the official gazette of Japanese Utility Model Laid-Open No. Hei 1-147483. The commodity takeout unit successively takes out commodities from a commodity string on a tilted commodity rack, including a reciprocatively rotatable control member. Commodities are successively taken out from a commodity rack starting with one present at an end of a commodity string by reciprocatively rotating the control member and alternately protruding the both ends of the member onto a commodity rack.
Another example of this type of the commodity takeout unit of an automatic vending machine is disclosed in Japanese Patent Laid-Open No. Hei 5-197877. The commodity takeout unit includes two hinge-type stoppers rotatably connected each other. Commodities stored in a commodity route in line are successively taken out starting with one present at an end of a commodity string by alternately protruding the curved portions of two stoppers to the commodity route.
However, malfunction may occur that not only the commodity at the end of the commodity string but also an adjacent commodity are taken out by getting over the control member or stopper.
Therefore, it is an object of the present invention to provide an commodity takeout unit of an automatic vending machine capable of securely taking out only the commodity at an end of a commodity string.
DISCLOSURE OF THE INVENTION
According to an aspect of the present invention, it is possible to obtain a commodity takeout unit of an automatic vending machine provided with a pair of arm movable between the work position protruding to a commodity route and the retreat position retreating from the commodity route and a driving member for driving the arms with a time difference.
Because the commodity takeout unit of an automatic vending machine is provided with a driving member for driving a pair of arms with a time difference, it is possible to move one arm to a position nearby the work position while holding the other at the work position and then, move the other arm to the retreat position and the one arm to the work position. Resultingly, the commodity at an end of a commodity string stored in a commodity route and the commodity at the second position from the end of the commodity string are temporarily held by the arms at the same time and then, the commodity at the end of the commodity string loses the support by the other arm and it is taken out of the commodity route.
Moreover, after taking out the commodity at an end of a commodity string, the commodity takeout unit of an automatic vending machine can move one arm from the retreat position to the work position when the other arm slightly moves from the retreat position to the work position and then, move the other arm to the retreat position. Resultingly, the commodity located at the end of the commodity string loses the support by the other arm and moves toward one arm, other commodities of the commodity string also move toward one arm, the commodity at the end of the commodity string is held by one arm present at the work position, and resultingly every commodity of the commodity string is held by one arm present at the work position.
Moreover, according to another aspect of the present invention, it is possible to obtain a commodity takeout unit of an automatic vending machine provided with a boxy case in which a first aperture is formed at one end of its apex and a second aperture is formed at the other end of its apex; a first arm set in the case, supported by the case so as to be rotatable about the axis line passing through the proximal portion, and movable between the work position passing through the first aperture and standing above the case and the retreat position falling into the case; an inte
