Abstract

A wheel balancing system determines a type of corrective weight for application to an edge of a rim of a wheel for correcting imbalance of the wheel. One or more corrective weights are identified from a varied inventory of corrective weights. An inventory database is incremented or decremented for each identified corrective weight. Database reports can be generated that specify weight usage and inventory status. One or more wheel balancers may be coupled to a network.

Claims

1. A wheel balancing system comprising:

a scanning device for providing measured dimensions of a wheel rim configuration;

a memory; and

a controller coupled to the scanning device and the memory and configured to identify a corrective weight appropriate for application to the wheel rim and to increment or decrement an inventory database, stored in the memory, in correspondence with the identified corrective weight.

2. A system as recited in claim 1, wherein the database comprises an inventory of a plurality of types and values of corrective weights, including clip-on weight types, adhesive weight types, and weights identified by color code.

3. A system as recited in claim 1, wherein the controller is coupled to a network.

4. A system as recited in claim 3, further comprising a plurality of said scanning devices with respective memories and controllers, the plurality of controllers coupled to the network.

5. An apparatus as recited in claim 4, further comprising a display device coupled to each controller for displaying weight inventory information.

6. An apparatus as recited in claim 5, wherein the weight inventory information comprises a report specifying weight usage during a set time period.

7. An apparatus as recited in claim 5, wherein the weight inventory information comprises an alert identifying a low inventory condition.

8. An apparatus as recited in claim 7, wherein the network is coupled to a remote site for transmission of weight inventory information.

9. An apparatus as recited in claim 4, wherein the controller is configured to transmit to a network site an order for resupply of inventory.

10. An apparatus as recited in claim 4, further comprising a printer coupled to the network and shared by the plurality of controllers.

11. A method for tracking wheel balance corrective weight usage comprising the steps of:

identifying, from a variety of corrective weights, one or more corrective weights to be applied to a wheel during each wheel balancing procedure; and

generating a cumulative account of types, weight amounts and quantities of weights that have been identified in the identifying step for a plurality of wheel balancing procedures.

12. A method as recited in claim 11, wherein the step of generating comprises incrementing or decrementing a corrective weight database, and the steps of identifying and generating are performed by a wheel balancing apparatus.

13. A method as recited in claim 12, wherein the corrective weight database is shared by a plurality of wheel balancing apparatuses.

14. A method as recited in claim 11, the variety of corrective weights comprise clip-on weight types, adhesive weight types, and weights identified by color code.

15. A method as recited in claim 11, wherein the variety of corrective weights comprises a plurality of types of corrective weights and weight values for each weight type, and the generating step comprises formulating a database report specifying corrective weight inventory status.

16. A method as recited in claim 15, wherein the report specifies the total amount incremented or decremented for each weight type and weight value during a set time period.

17. A method as recited in claim 16, wherein the step of generating further comprises defining adjustable recurring report periods.

18. A method as recited in claim 15, wherein the step of generating further comprises downloading the report to a network site.

19. A method as recited in claim 12, further comprising the step of generating an alert when the database has been incremented or decremented to a specified threshold.

20. A method as recited in claim 19, further comprising transmitting to a network site an order for resupply of corrective weights in response to the alert.
