Clear door vending machine
Vending machine product is moved by the use of an “X-Y mechanism” having two stationary electronically controlled drive “motors”. These motors drive (directly or indirectly) tension elements (belt, chain, cable, etc.) that position horizontally and vertically sliding components. A separation and selection system uses a “rotator” to release a product from a tray and a “gate” to separate the products into two columns on the tray. A “lever” (centered by springs) mechanically links these components. Products move off the tray by a spring powered “slider” (one slider for each product column) on the tray. There is only one “rotator-gate-lever” mechanism per pair of product columns in each display tray. That is, when a “cup” engages the “lever” moving to the right, a product from the left side of the display tray is pushed into the “cup” and vice versa. Adjustable side walls in each tray accommodate different sized packages. The delivery mechanism uses the “cup” for transport. A lower surface of the cup engages a sliding “door” to a balanced delivery “port” for delivery of product from the cup to the port. Delivery is made from the cup to the port simultaneously with the opening of the door.
1. A product separation and selection tray system for a vending machine having a plurality of shelves, said product separation and selection tray system comprising
a tray for holding two columns of product to be mounted on the shelves in the vending machine,
a central wall for separating the two columns of product on opposite sides of the wall,
two side walls located on opposite sides of the central wall, and
a support assembly mounted on the central wall, the support assembly adjustably controlling a separation distance between the two side walls.
2. The product separation and selection tray system as claimed in claim 1 , wherein the two sidewalls are laterally adjustable towards and away from the central wall by release and actuation of the support assembly so as to accommodate different sized products.
3. The product separation and selection tray system as claimed in claim 1 , further comprising a spring and a pushbar, the push bar slides on the tray by the force of the spring to move product along the tray.
4. The product separation and selection tray system as claimed in claim 3 , wherein the spring comprises a wound tape which biases the push bar.
5. The product separation and selection tray system as claimed in claim 3 , wherein the spring is rotatably mounted on a push tray.
6. The product separation and selection tray system as claimed in claim 5 , wherein the spring further comprises and elongated portion extended to create a bias force for return of the push tray to an at rest position.
7. The product separation and selection tray system as claimed in claim 1 , wherein the support assembly includes indicia for relative identical positioning of each of the two side walls from the central wall.
8. The product separation and selection tray system as claimed in claim 1 , wherein said support assembly controls a relative positioning of an upper portion and a lower portion of each side wall with respect to said central wall.
9. The product separation and selection tray system as claimed in claim 7 , wherein said indicia is fixed in position and the system further comprise two straps extending between the side walls of the central wall are moveable to vary the separation distance between the central wall and the side walls.
10. The product separation and selection tray system as claimed in claim 9 , wherein said two straps are fixed at the side walls and movable with respect to the support assembly.
