Abstract

An automated food making apparatus is described. An automated food making apparatus can include: a carousel; a dispensing apparatus shared among a plurality of canisters on the carousel, wherein at least one canister includes a paddle; and wherein the dispensing apparatus is configured to rotate the canister's paddle to dispense ingredients stored in the canister. A dispensing mechanism for an automated food making apparatus can include: an actuator arm; a motor that is adapted to rotate the actuator arm; one or more magnets embedded in the actuator arm; and one or more sensors configured to detect position of the actuator arm; wherein the actuator arm dispenses ingredients by rotating a pin located on a canister.

Claims (23)

1. A dispensing mechanism for an automated food making apparatus, comprising:

an actuator arm having a top arm and a bottom arm;

a motor having a motor shaft, the motor adapted to rotate the top arm and the bottom arm of the actuator arm;

a pin located on a canister and configured to engage with the actuator arm;

a top magnet and a bottom magnet, each embedded in the actuator arm, wherein the top magnet is aligned with the top arm and the bottom magnet is aligned with the bottom arm; and

one or more sensors configured to detect a position of the actuator arm based on a position of the top magnet or the bottom magnet,

wherein the actuator arm dispenses ingredients by rotating the pin with the top arm and the bottom arm.

2. The dispensing mechanism of claim 1 , wherein:

the one or more sensors comprise hall sensors.

3. The dispensing mechanism of claim 1 , wherein:

the motor comprises a stepper motor.

4. The dispensing mechanism of claim 1 , wherein:

the motor comprises a servo motor.

5. The dispensing mechanism of claim 1 , wherein the motor shaft is configured to rotate the actuator arm.

6. The dispensing mechanism of claim 1 , wherein the position of the actuator arm is based on a position of the top magnet or the bottom magnet with respect to the one or more sensors.

7. The dispensing mechanism of claim 1 , wherein the one or more sensors provides feedback to a printed circuit board.

8. The dispensing mechanism of claim 1 , wherein the one or more sensors are configured to determine a rest position of the pin after a dispensing operation is complete.

9. The dispensing mechanism of claim 1 , further comprising a dispenser motor assembly comprising the actuator arm, the motor shaft, a plate, and a motor cover.

10. The dispensing mechanism of claim 9 , wherein the one or more sensors are located in the plate.

11. The dispensing mechanism of claim 1 , wherein the pin is coupled to a paddle, the paddle configured to dispense ingredients from the canister upon rotation by the actuator arm.

12. The dispensing mechanism of claim 1 , wherein the one or more sensors comprise a plurality of sensors.

13. The dispensing mechanism of claim 1 , wherein the one or more sensors comprise two hall sensors.

14. The dispensing mechanism of claim 1 , wherein the one or more sensors comprise a single hall sensor.
