Abstract
There is provided n article storage/dispensing device for a vending machine. Each article rack for storing articles has an article passage for storing the articles in a horizontal row, and a dispensing opening formed at one end of the article passage for dispensing the articles. Each article-dispensing mechanism is provided for the corresponding article rack in a manner movable between a dispensing position and a holding position. A single drive source causes each article-dispensing mechanism to move between the dispensing position and the holding position. Each linkage is capable of connecting the drive source to the corresponding article-dispensing mechanism and disconnecting the former from the latter, for causing the corresponding article-dispensing mechanism to move from the holding position to the dispensing position when the drive source is connected to the corresponding article-dispensing mechanism. Driving means actuates a linkage corresponding to an article selected by a purchaser, thereby connecting the drive source to an article-dispensing mechanism corresponding to the selected article, for vending the article.

-
a plurality of article racks each for storing a plurality of articles, each of said plurality of article racks having an article passage formed therein for storing said plurality of articles in a horizontal row, and a dispensing opening formed at one end of said article passage for dispensing said articles therefrom;
a plurality of article-dispensing mechanisms each provided for one of said plurality of article racks corresponding thereto in a manner movable between a dispensing position for dispensing said articles from said dispensing opening and a holding position for holding said articles within said article passage;
a single drive source for causing said plurality of article-dispensing mechanisms to move between said dispensing position and said holding position;
a plurality of linkages each capable of connecting said drive source to one of said plurality of article-dispensing mechanisms corresponding thereto and disconnecting said drive source from said one of said plurality of article-dispensing mechanisms, for causing said one of said plurality of article-dispensing mechanisms to move from said holding position to said dispensing position when said drive source is connected to said one of said plurality of article-dispensing mechanisms; and
driving means for selectively actuating one of said plurality of linkages which corresponds to an article selected by a purchaser, thereby connecting said drive source to one of said plurality of article-dispensing mechanisms which corresponds to said article selected by said purchaser, for vending said article selected by said purchaser. - View Dependent Claims (2, 3, 4, 5, 6)
said plurality of linkages each including a reciprocating member which can be connected to or disconnected from said motor, said reciprocating member being driven for reciprocating motion interlocked with rotation of said motor when said reciprocating member is connected to said motor, thereby causing said one of said plurality of article-dispensing mechanisms which corresponds to said article selected by said purchaser to reciprocate between said holding position and said dispensing position, and said driving means connecting said reciprocating member of said one of said plurality of linkages which corresponds to said article selected by said purchaser to said motor, for vending said article selected by said purchaser. -
4. An article storage/dispensing device according to claim 3, wherein each of said plurality of linkages further includes a gear mechanism,
said gear mechanism comprising a first gear driven by said motor for rotation, and a second gear formed with gear teeth which can mesh with said first gear, and a cut-away portion formed by cutting away a portion of said gear teeth for inhibiting said second gear from engaging with said first gear via said cut-away portion, said reciprocating member being connected to said second gear such that said reciprocating member performs one cycle of reciprocating motion in accordance with one rotation of said second gear, and said driving means including second gear-driving means for normally positioning said second gear at a rotational angle position in which said cut-away portion is opposed to said first gear, and causing said second gear of said gear mechanism of said one of said plurality of linkages which corresponds to said article selected by said purchaser to rotate to a rotational angle position in which said gear teeth of said second gear are brought into meshing engagement with said first gear, for vending said article selected by said purchaser. -
5. An article storage/dispensing device according to any one of claims 1 to 4, further comprising an elevator arranged within a body of said vending machine at a location outward of said one end of said article passage of each of said plurality of article racks in a manner movable upward and downward, for stopping in a stop position close to said dispensing opening to receive said article selected by said purchaser,
said driving means comprising a plurality of push rods provided in a manner corresponding to said plurality of article-dispensing mechanisms, respectively, and each extending in a front-rear direction between a vicinity of said dispensing opening and a vicinity of a corresponding one of said plurality of linkages, and urging means arranged in said elevator for urging one end of one of said plurality of push rods which corresponds to said article selected by said purchaser in said front-rear direction toward said corresponding one of said plurality of linkages when said elevator stops in said stop position, said corresponding one of said plurality of linkages being driven by engagement with another end of said one of said plurality of push rods which corresponds to said article selected by said purchaser, for connecting said drive source to said one of said plurality of article-dispensing mechanisms which corresponds to said article selected by said purchaser. -
6. An article storage/dispensing device according to any one of claims 1 to 4, further comprising a shelf having said drive source and said plurality of linkages provided therefor, and said plurality of article racks placed thereon,
wherein a plurality of mounting portions are arranged vertically within a body of said vending machine which accommodates said plurality of article racks, so as to allow said shelf to be selectively mounted to one of said plurality of mounting portions.
