Abstract

Claims (50)

1 . A method for automatically filling skived areas on a tire carcass, the method comprising:

analyzing, by a computer system, a surface of the tire carcass with a sensor;

identifying, by the computer system, a first skived area of the tire carcass;

determining, by the computer system, whether to perform a filling operation to fill the first skived area;

communicating, by the computer system, a location of the first skived area to a filling device responsive to a determination to perform the filling operation;

translating the filling device to a position proximate the location of the first skived area, the filling device coupled with a circumferential rail extending circumferentially around the tire carcass such that the filling device circumferentially translates along the surface of the tire carcass; and

filling, by the filling device, the first skived area.

2 . The method of claim 1 , wherein determining whether to perform the filling operation to fill the first skived area comprises:

determining, by the computer system, a first depth of the first skived area; and

determining, by the computer system, that the first depth of the first skived area is greater than a predetermined depth threshold.

3 . The method of claim 2 , further comprising:

determining, by the computer system, a second depth of a second skived area;

determining, by the computer system, that the second depth of the second skived area is greater than the predetermined depth threshold; and

filling, by the filling device, the second skived area responsive to determining that the second depth of the second skived area is greater than the predetermined depth threshold.

4 . The method of claim 1 , further comprising:

identifying, by the computer system, a plurality of skived areas of the tire carcass;

mapping, by the computer system, the plurality of skived areas to create a coordinate map of the plurality of skived areas;

generating, by the computer system, a filling path based on the coordinate map;

sending, by the computer system, the filling path to the filling device; and

automatically filling the plurality of skived areas with the filling device, the filling device following the filling path by translating along the circumferential rail.

5 . The method of claim 4 , wherein the filling path includes a shortest tool path for the filling device to fill in the plurality of skived areas.

6 . The method of claim 4 , wherein the filling path is generated such that operation of the filling device is offset from operation of a skiving device.

7 . A system for automatically filling skived areas on a tire carcass, the system comprising:

a scanner;

a filling device;

a circumferential rail that extends circumferentially around the tire carcass, the filling device configured to couple with and translate along the circumferential rail such that the filling device circumferentially translates along a surface of the tire carcass; and

a controller communicatively coupled to the scanner and the filling device, the controller comprising a processor and a memory configured to store instructions to cause the controller to perform operations comprising:

analyze, using the scanner, the surface of the tire carcass;

identify a first skived area of the tire carcass;

determine whether to perform filling of the first skived area; and

provide an instruction to the filling device to fill the first skived area.

8 . The system of claim 7 , wherein the filling device is operably coupled to an industrial robot having a robotic arm configured to position the filling device circumferentially about the surface of the tire carcass when the tire carcass is operably coupled to the system.

9 . The system of claim 7 , further comprising a mandrel configured to couple to the tire carcass and configured to rotate the tire carcass in response to receiving a rotational signal from the controller.

10 . The system of claim 7 , wherein the instructions further cause the controller to:

cause the filling device to be positioned in confronting relation to the tire carcass; and

translate the filling device circumferentially and axially about the tire carcass.

11 . The system of claim 7 , wherein the instructions further cause the controller to:

determine a first depth of the first skived area;

determine whether the first depth of the first skived area is greater than a predetermined depth threshold; and

provide an instruction to the filling device to fill the first skived area responsive to determining that the first depth of the first skived area is greater than the predetermined depth threshold.

12 . The system of claim 11 , wherein the instructions further cause the controller to:

determine a second depth of a second skived area;

determine whether the second depth of the second skived area is greater than the predetermined depth threshold; and

provide an instruction to the filling device to fill the second skived area responsive to determining that the second depth of the second skived area is greater than the predetermined depth threshold.

13 . The system of claim 7 , wherein the instructions further cause the controller to:

generating a filling path for filling the first skived area;

sending the filling path to the filling device; and

providing an instruction to the filling device to perform a filling operation to fill the first skived area by the filling device by following the filling path.

14 . The system of claim 13 , wherein the filling path corresponds to a shortest tool path the filling device travels during filling.

15 . The system of claim 13 , wherein the instructions are configured to determine a timing of the filling operation based at least in part on a timing of a skiving operation by a skiving device such that the filling operation is offset from the skiving operation.
