Abstract
In a commodity discharge apparatus for a vending machine, an endless chain (2) extends on a vertical plane to form an endless loop and is engaged with a first and a second sprocket (1a, 1b) which are spaced from each other in a horizontal direction. The endless chain is adapted to circulate through the first and the second sprockets and through a lower and an upper traveling path each extending between the first and the second sprockets. A hook (3) is unrotatably attached to a part of the endless chain and is for hooking a commodity (100) only when the part is placed at the lower traveling path. In addition, a fall preventing member (7) is provided to extend in parallel to the lower traveling path beside the hook for preventing a fall of the commodity from the hook.
Claims16
A commodity discharge apparatus for a vending machine, comprising:
- fist and second sprockets spaced from each other in a horizontal direction;
- an endless chain engaged with said first and second sprockets and extending on a vertical plane to form an endless loop, said endless chain being adapted to circulate through said first and second sprockets and through a lower and an upper traveling path each extending between said first and second sprockets;
- a hook unrotatably attached to a part of said endless chain for hooking a commodity only when said part is placed at said lower traveling path;
- a fall preventing member extending parallel to said lower traveling path and beside said hook for preventing a fall of said commodity from said hook, said fall preventing member being movable between an operating position and a retracted position which is retracted over said operating position, said operating position having a level substantially equal to a level of a fee end of said hook;
- and
- a driving member connected to said fall preventing member for driving the movement of said fill preventing member from said operating position to said retracted position.
A commodity discharge apparatus for a vending machine, comprising:
- first and second sprockets spaced from each other in a horizontal direction;
- an endless chain engaged with said first and second sprockets and extending on a vertical plane to form an endless loop, said endless chain being adapted to circulate through said first and second sprockets and through a lower and an upper traveling path each extending between said first and second sprockets;
- a hook unrotatably attached to a part of said endless chain for hooking a commodity only when said part is placed at said lower traveling path, said hook being moved from said first sprocket towards said second sprocket when said part of said endless chain passes through said lower traveling path;
- a fall preventing member extending parallel to said lower traveling path. beside said hook for preventing a fall of said commodity from said hook;
- and
- a release promoting member placed in a vicinity of said second sprocket for promoting a release of said commodity from said hook in cooperation with movement of said hook, said release promoting member having an edge portion that extends in a substantially vertical direction and engages said commodity to remove said commodity from said hook.
A commodity discharge apparatus for a vending machine, comprising:
- first and second sprockets spaced from each other in a horizontal direction;
- an endless chain engaged with said first and second sprockets and extending on a vertical plane to form an endless loop, said endless chain being adapted to circulate through said first and second sprockets and through a lower and an upper traveling path each extending between said first and second sprockets;
- a hook unrotatably attached to a part of said endless chain for hooking a commodity only when said part is placed at said lower traveling part, said hook being moved from said first sprocket towards said second sprocket when said part of said endless chain passes through said lower traveling path;
- a fall preventing member extending parallel to said lower traveling path beside said hook for preventing a fall of said commodity from said hook;
- and
- a release promoting member placed in the vicinity of said second sprocket for promoting a release of said commodity from said hook in cooperation with movement of said hook, said release promoting member having an edge portion which is engaged with said commodity to remove said commodity from said hook when said part of the endless chain passes through said second sprocket, a free end of said hook being movable to define a locus when said part of the endless chain passes through said second sprocket, said edge portion extending in a vicinity of said locus, and said edge portion extending in a vertical direction in a vicinity of a farthest point on said locus, said farthest point being farthest from said second sprocket in said horizontal direction among other points on said locus.
