Abstract

The present invention provides for a vending system wherein a monitoring system verifies that a product ordered by a vending customer is actually delivered through a delivery area to the customer. If the product ordered is unavailable either because of an out of stock situation or a blockage of the delivery path for that product, the present invention allows the customer to request a refund or order a second product. Additionally, the present invention helps to prevent theft of product from the vending system.

Claims

1. An apparatus for facilitating delivery of a product from a vending machine, the vending machine having an ordering system for accepting a customer order of the product, at least one delivery mechanism associated with the product and a delivery path for delivering the product, the delivery mechanism moving from and returning to a home position in response to the customer order, the apparatus comprising:

a monitoring system located about the delivery path, the monitoring system determining if a product passes along the delivery path; and

a circuitry communicatively coupled to the monitoring system, the circuitry determining a failure if the product does not pass along the delivery path in response to a customer order, and in response to detection of movement of the delivery mechanism from and return of the delivery mechanism to the home position, the circuitry instructing the at least one delivery mechanism to move from the home position in response to the failure and to subsequently stop in response to the product passing along the delivery path.

2. The apparatus of claim 1 wherein the at least one delivery mechanism returns to the home position when a subsequent order is placed for the product.

3. The apparatus of claim 2 wherein the circuitry instructs the at least one delivery mechanism to stop at the home position if a delivery associated with the subsequent order is not detected by the monitoring system.

4. The apparatus of claim 2 wherein the circuitry instructs the at least one delivery mechanism to move beyond the home position if a delivery associated with the subsequent order is not detected by the monitoring system.

5. The apparatus of claim 1 wherein the monitoring system comprises a set of signal emitters and a set of signal detectors.

6. The apparatus of claim 5 wherein the monitoring system sequentially activates each of the signal emitters in the set of signal emitters.

7. The apparatus of claim 6 wherein the circuitry determines the passing of the product through the delivery path when at least one signal detector associated with one of the set of signal emitters is not illuminated when the one of the set of signal emitters is activated.

8. A method of facilitating the delivery of a product from a vending machine, the vending machine having an ordering system for accepting a customer order of the product, at least one delivery mechanism associated with the product and a delivery path for delivering the product, the at least one delivery mechanism moving from and returning to a home position in response to the customer order, the method comprising:

monitoring the delivery path with a monitoring system located about the delivery path;

instructing the at least one delivery mechanism to move in response to a failure of the product to pass along the delivery path in response to the customer order and despite detection of movement of the delivery mechanism from and return of the delivery mechanism to the home position; and

instructing the at least one delivery mechanism to stop moving in response to a subsequent passing of the product along the delivery path.

9. The method of claim 8, the method further comprising:

instructing the at least one delivery mechanism to return to the home position in response to a subsequent customer order.

10. The method of claim 9, the method further comprising:

instructing the at least one delivery mechanism to continue beyond the home position if a delivery is not detected in response to the subsequent customer order.

11. The method of claim 9 wherein the monitoring system comprises a set of signal emitters and a set of signal detectors.

12. The method of claim 11 the method further comprising:

sequentially activating each of the signal emitters in the set of signal emitters.

13. The method of claim 12 wherein the circuitry determines the passing of the product through the delivery path when at least one signal detector associated with one of the set of signal emitters is not illuminated when the one of the set of signal emitters is activated.

14. A vending machine for delivering at least one product in response to a customer order, the vending machine comprising:

an ordering system for accepting the customer order of the product;

at least one delivery mechanism associated with the at least one product, the at least one delivery mechanism moving from and returning to a home position in response to the customer order;

a delivery path for delivering the product;

a monitoring system located about the delivery path, the monitoring system determining if a product passes along the delivery path; and

a circuitry communicatively coupled to the monitoring system and the at least one delivery mechanism, the circuitry instructing the at least one delivery mechanism to move beyond the home position if movement of the delivery mechanism from and return of the delivery mechanism to the home position in the response to the customer order is detected but does not cause the product to pass along the delivery path, and to subsequently stop in response to the product passing along the delivery path.

15. The vending machine of claim 14 wherein the at least one delivery mechanism returns to the home position when a subsequent order is placed for the product.

16. The vending machine of claim 14 wherein the circuitry instructs the at least one delivery mechanism to move beyond the home position if a product delivery associated with the subsequent order is not detected.

17. The vending machine of claim 14 wherein the monitoring system comprises a set of signal emitters and a set of signal detectors, the monitoring system sequentially activating each of the signal emitters in the set of signal emitters.
