Abstract

Providing quality management and intelligent manufacturing with labels and smart tags in event-based product manufacturing. Some of the disclosed embodiments include a system, method, and computer-readable media for storing, during a process, data associated with a material. Also disclosed are a method of collecting, storing, and reporting machine productivity, waste, and delay information on an event basis in a manufacturing system, a method of capturing and storing material history, a method of automating tracking of positions of components used in a process and correlating portions of a component with production problems, an improved inventory management system, and a method of tracking and recording actions of specific operators of a process performed by a machine. The embodiments are operable in an intelligent manufacturing system including a process for converting raw materials to a product, a process control system including one or more sensors capable of generating an alarm in response to an event that results in one of waste, machine delay, or decrease product quality, a data logger associated with the process control system for obtaining event parameters associated with the event, a database on a server for recording event parameters obtained by the data logger, and a reporting system cooperatively associated with the database for reporting productivity parameters regarding the process derived at least in part from the event parameters.

Claims

1. A method for collecting, storing, and reporting machine productivity, waste, and delay information on an event basis in a manufacturing system, the method comprising:

monitoring an event via a process sensor;

detecting an event trigger in response to the monitoring;

obtaining data in response to the detecting, the data comprising a process variable from a control system, a measure of the waste, delay, or quality loss associated with the event, and operator input;

automatically validating the obtained data;

formatting and recording the validated data; and

generating a report based on the recorded data.

2. The method of claim 1, further comprising assuring quality of the recorded data by performing error checking on the recorded data.

3. The method of claim 1, further comprising:

embedding a plurality of identification devices in a material;

monitoring the plurality of identification devices as the material passes through a component in the manufacturing system, wherein obtaining the data comprises obtaining material position data indicating a position of the material with respect to the component;

storing the material position data in a database comprising or operatively associated with the obtained data; and

correlating the stored material position data with a quality control issue to identify corrective action.

4. The method of claim 3, wherein the embedding comprises embedding a plurality of identification devices at various locations in a material, and wherein the monitoring comprises monitoring by a scanning device in a machine.

5. The method of claim 3, wherein the correlating comprises correlating via fuzzy logic.

6. The method of claim 3, wherein the correlating comprises correlating the stored material position data with the quality control issue to identify one or more of the following:

repairs, modification to production methods, and modifications to the component.

7. The method of claim 3, wherein monitoring the plurality of identification devices comprises monitoring the plurality of identification devices as the material passes through one or more of the following in the manufacturing system:

a moving device, a belt, and a wire.

8. The method of claim 3, wherein the plurality of identification devices comprises a smart tag.

9. The method of claim 1, wherein monitoring the event comprises monitoring at least one identification device associated with a material from a first process, and further comprising:

determining a physical location of the material in response to the monitoring to use the material in a second process; and

associating the determined physical location of the material with the obtained data.

10. The method of claim 9, wherein generating the report comprises generating at least one report based on the determined physical location.

11. The method of claim 9, wherein monitoring the at least one identification device comprises monitoring the at least one identification device associated with one or more of the following:

a roll, a pallet, and a box of materials.

12. The method of claim 9, wherein the identification device comprises an ultra-wide band transmitter emitting a signal, and the determining comprises triangulating the physical location of the material based on the emitted signal.

13. The method of claim 9, wherein the identification device comprises a smart tag emitting a radio frequency signal, and the monitoring comprises receiving, from a scanning device, the emitted radio frequency signal.

14. The method of claim 1, wherein one or more computer-readable media have computer-executable instructions for performing the method of claim 1.

15. A system comprising:

a memory area for storing a data structure in an event-based manufacturing system, said data structure representing event data for a material, the data structure comprising one or more fields for storing data describing characteristics of the material and the event; and

a processor configured to execute computer-executable instructions for;

monitoring the event via a process sensor;

detecting an event trigger in response to the monitoring;

obtaining data in response to the detecting, said obtained data describing characteristics of the material and the event;

populating the fields of the data structure stored in the memory area with the obtained data;

automatically validating the data stored in the fields of the data structure;

formatting and recording the validated data; and

generating a report based on the recorded data.

16. The system of claim 15, wherein the obtained data comprises one or more of the following:

a process variable from a control system;

a measure of the waste, delay, or quality loss associated with the event; and

operator input.

17. The system of claim 15, wherein the material comprises one or more of the following:

an intermediate product and a raw material.

18. The system of claim 15, wherein the characteristics comprise one or more of the following:

product waste, machine down time, machine slow downs, product maintenance, and machine failure.

19. The system of claim 15, wherein the one or more fields comprise an output table storing one or more of the following:

a machine reference field identifying the machine, a timestamp field defining the date and time of the event data, a delay code field identifying a type of delay, a delay trigger field indicating an origin of delay, a grade shift field representing a shift in production parameters, operator comments, and a duration field representing a delay length.

20. The system of claim 15, wherein the one or more fields comprise a support table interpreting the characteristics, the support table comprising one or more of the following:

a delay code field identifying a type of delay, a description field describing the delay code, a programmable logic controller field associated with the delay code, a section field identifying a machine section relating to the event data, a machine type field identifying a type of machine, an alarm source field indicating alarm origin.
