Enhanced automated food making apparatus
A method for operating an automated food making apparatus having a motor, actuator arm, and an apparatus. The apparatus may be a paddle with flexible fins. The method rotates the paddle with a pin-shaft mechanism to dispense an ingredient placed in a canister, controls the motor automatically based on weight sensor readings, and locates a position of the actuator arm with position sensors. The same motor dispenses ingredients from a plurality of canisters. The method may have a plurality of paddle rotation and weight measurement steps until a target weight is reached. The plurality of paddle rotation steps may be unidirectional or bidirectional paddle rotation. The paddle may be rotated according to one or more paddle rotation algorithms, an error recovery algorithm, or different algorithms based on the amounts of ingredients remaining in the canister. The paddle may be rocked until the target weight is achieved.
1. A method of operating an automated food making apparatus comprising:
rotating an actuator arm with a motor;
rotating, with the actuator arm, a pin coupled to a shaft;
rotating, with the pin and the shaft, a plurality of rollers distributed circumferentially around the shaft to dispense a liquid placed in a bottle of a canister; and
controlling the motor automatically based on weight sensor readings,
wherein the motor is configured to dispense ingredients from a plurality of canisters, and
wherein the pin is located on the canister and is coupled to the shaft, which extends into an interior of the canister.
2. The method of claim 1 , wherein the plurality of rollers form a peristaltic pumping apparatus for dispensing the liquid.
3. The method of claim 1 , further comprising:
maintaining the bottle in a predetermined position with supports.
4. The method of claim 1 , further comprising transporting the liquid to with tubing.
5. The method of claim 1 , further comprising:
monitoring the weight sensor readings after different dispensing motions and providing feedback to the motor.
6. The method of claim 1 , further comprising:
dispensing the liquid from the bottle through a flexible tube; and
compressing the flexible tube with the plurality of rollers to control the dispensing of the liquid.
7. The method of claim 6 , further comprising:
reducing dripping of the liquid with a one way valve added to an end of the flexible tube.
8. The method of claim 1 , wherein the plurality of rollers compress a tube through which the liquid is dispensed from the bottle.
9. The method of claim 1 , further comprising reversing the flow in the canister to reduce drips.
10. The method of claim 1 , further comprising:
dispensing a desired amount of liquid;
detecting a drip from the canister; and
activating a liquid pullback step.
11. The method of claim 10 , wherein detecting the drip from the canister comprises detecting a weight increase between dispensing.
12. The method of claim 1 , wherein the actuator arm comprises a first arm and a second arm, and wherein rotating the pin comprises engaging the first arm with a first end of the pin and the second arm with a second end of the pin.
13. The method of claim 1 , wherein the pin extends perpendicularly to the shaft.
14. A method of operating an automated food making apparatus comprising:
rotating an actuator arm with a motor;
rotating, with the actuator arm, a pin coupled to a shaft;
rotating, with the pin and the shaft, a plurality of rollers distributed circumferentially around the shaft to dispense a liquid placed in a bottle of a canister; and
controlling the motor automatically based on weight sensor readings,
wherein the motor is configured to dispense ingredients from a plurality of canister, and
wherein the actuator arm comprises a first arm and a second arm, and wherein rotating the pin comprises engaging the first arm with a first end of the pin and the second arm with a second end of the pin.
15. A method of operating an automated food making apparatus comprising:
rotating an actuator arm with a motor;
rotating, with the actuator arm, a pin coupled to a shaft;
rotating, with the pin and the shaft, a plurality of rollers distributed circumferentially around the shaft to dispense a liquid placed in a bottle of a canister; and
controlling the motor automatically based on weight sensor readings,
wherein the motor is configured to dispense ingredients from a plurality of canisters, and
wherein the pin extends perpendicularly to the shaft.
