Abstract

Disclosed embodiments provide a liquid product dispensing system. Cans are transported onto a weigh plate. The weigh plate is coupled to a dispensing system such that, when the can is filled with product to a predetermined weight, the dispensing system stops the flow of product into the can. A transport system then moves the filled cans from the weigh plate and moves another set of empty cans onto the weigh plate, and the process continues, enabling high-speed production of canned beverages.

Claims

1. A liquid product dispensing system, comprising:

a balance apparatus, the balance apparatus comprising;

a balance arm;

a weigh plate disposed on a distal end of the balance arm;

a counterweight adjustably disposed on the balance arm;

a fulcrum block disposed at an intermediate position on the balance arm, wherein the balance arm is configured and disposed to pivot at the fulcrum block;

a sensor configured and disposed to generate a trigger event in response to a predetermined weight being loaded on the weigh plate;

a dispensing system comprising a liquid dispensing port, and wherein the dispensing system is configured and disposed to stop dispensing upon detecting the trigger event from the sensor.

2. The liquid product dispensing system of claim 1, wherein the sensor comprises a contact sensor.

3. The liquid product dispensing system of claim 1, wherein the sensor comprises a proximity sensor.

4. The liquid product dispensing system of claim 1, wherein the sensor comprises an optical sensor.

5. The liquid product dispensing system of claim 1, further comprising a weigh plate lockdown mechanism configured and disposed to secure the weigh plate in a horizontal orientation.

6. The liquid product dispensing system of claim 5, wherein the weigh plate lockdown mechanism comprises an actuator configured and disposed to contact the balance arm on an opposite side of the fulcrum block from the weigh plate.

7. The liquid product dispensing system of claim 5, further comprising a controller configured and disposed to control the liquid product dispensing system, the controller comprising:

a processor;

an input/output interface coupled to the processor;

a memory coupled to the processor, wherein the memory contains instructions, that when executed by the processor, perform steps including;

activating the weigh plate lockdown mechanism;

operating a transport mechanism to place a can on the weigh plate;

deactivating the weigh plate lockdown mechanism;

starting product dispensing;

in response to detecting a full condition via the input/output interface, ending product dispensing;

reactivating the weigh plate lockdown mechanism; and

operating the transport mechanism to remove the can from the weigh plate.

8. The liquid product dispensing system of claim 7, wherein the transport mechanism comprises a feed screw.

9. The liquid product dispensing system of claim 1, further comprising a stopping block configured and disposed to prevent downward travel of the weigh plate when the weigh plate is in a horizontal orientation.

10. The liquid product dispensing system of claim 1, wherein the counterweight is coupled to a slide block, wherein the slide block is configured and disposed to adjustably attach to the balance arm.

11. The liquid product dispensing system of claim 10, further comprising a screw coupled to the counterweight and the slide block, wherein the screw is configured and disposed to adjust a position of the counterweight relative to the fulcrum block.

12. The liquid product dispensing system of claim 11, wherein the screw has a thread count ranging from 20 threads per inch to 40 threads per inch.

13. The liquid product dispensing system of claim 1, wherein the weigh plate has a rectangular top surface.

14. The liquid product dispensing system of claim 13, wherein the weigh plate top surface has a surface area ranging from 9 square inches to 16 square inches.

15. A liquid product dispensing system, comprising:

a product weighing system, comprising;

a weigh plate;

a strain gauge mechanically coupled to the weigh plate;

an electronic circuit configured and disposed to generate a trigger event in response to a predetermined strain indicated by the strain gauge;

a dispensing system comprising a liquid dispensing port, and wherein the dispensing system is configured and disposed to stop dispensing upon detecting the trigger event from the electronic circuit.

16. The liquid product dispensing system of claim 15, further comprising a controller configured and disposed to control the liquid product dispensing system, the controller comprising:

a processor;

an input/output interface coupled to the processor and the strain gauge;

a memory coupled to the processor, wherein the memory contains instructions, that when executed by the processor, perform steps including calibrating the strain gauge for a can volume.

17. The liquid product dispensing system of claim 16, wherein the memory further contains instructions, that when executed by the processor, perform steps including:

operating a transport mechanism to place a can of the can volume on the weigh plate;

starting product dispensing;

in response to detecting the trigger event, ending product dispensing; and

operating the transport mechanism to remove the can from the weigh plate.

18. The liquid product dispensing system of claim 15, wherein the weigh plate has a rectangular top surface.

19. The liquid product dispensing system of claim 18, wherein the weigh plate top surface has a surface area ranging from 9 square inches to 16 square inches.

20. A computer-implemented method for dispensing liquid product, comprising:

activating a weigh plate lockdown mechanism for a weigh plate;

operating a transport mechanism to place a can on the weigh plate;

deactivating the weigh plate lockdown mechanism;

starting product dispensing into the can;

in response to detecting a full condition for the can, ending product dispensing;

reactivating the weigh plate lockdown mechanism; and

operating the transport mechanism to remove the can from the weigh plate.
