A tire inspection device is disclosed. The disclosed tire inspection device for inspecting at least one tire being transferred from a tire sub-line to a tire mounting process along a transfer conveyor, may include i) a frame mounted to an outside of the transfer conveyor, ii) a first camera fixedly secured to the frame over the transfer conveyor configured to capture data from a surface of the at least one tire placed on the transfer conveyor, and iii) a controller configured to analyze the data captured by the first camera, detect a position of a balance marker on the surface of the at least one tire, and determine an orientation of the at least one tire based on the detected position of the balance marker.

1. A tire inspection device for inspecting at least one tire being transferred from a tire sub-line to a tire mounting process along a transfer conveyor, comprising: a frame mounted to an outside of the transfer conveyor;a first camera fixedly secured to the frame over the transfer conveyor configured to capture data from a surface of the at least one tire placed on the transfer conveyor; anda controller configured to analyze a vision data captured by the first camera, detect a position of a balance marker on the surface of the at least one tire, and determine an orientation of the at least one tire based on the detected position of the balance marker. 2. The device of claim 1, wherein the controller is further configured to determine that the at least one tire is in a correct orientation if, upon processing the data obtained from the first camera, the balance marker is recognized. 3. The device of claim 1, further comprising a second camera mounted to the frame on an outside of the transfer conveyor, the second camera configured to be movable to capture data regarding a tread portion color line. 4. The device of claim 3, wherein the controller is configured to analyze the vision data obtained by the second camera and compare a color of the tread portion color line to a reference color corresponding to a tire specification to determine the specification of the tire. 5. The device of claim 3, wherein the second camera is configured to be moveable in a vertical direction such that it can capture data regarding the tread portion color line of each at least one tire in a stack of tires on the transfer conveyor in multistage. 6. The device of claim 3, further comprising a laser displacement sensor fixedly secured to the frame over the transfer conveyor, the laser displacement sensor configured to measure a height of the stack of tires on the transfer conveyor in multistage. 7. The device of claim 6, wherein the frame has a mover mounted thereto for moving the second camera in a vertical direction. 8. The device of claim 7, wherein the mover includes;a servo motor fixedly mounted to the frame,a lead screw arranged on the frame in an vertical direction connected to the servo motor,a guide rail mounted to the frame parallel to the lead screw, anda slider screw coupled to the lead screw to be slideable on the guide rail for fixedly securing the second camera thereto. 9. The device of claim 7, wherein the controller is configured to control the mover according to the measured value of the laser displacement sensor. 10. A method for inspection of a tire comprising the steps of: providing a tire inspection device for inspecting at least one tire being transferred from a tire sub-line to a tire mounting process along a transfer conveyor;capturing, with a first camera, data regarding a surface of the at least one tire placed on the transfer conveyor, and forwarding a vision data to a controller;analyzing the vision data;detecting a position of a balance marker on the surface of the at least one tire; anddetermining an orientation of the tire based on the detected position of the balance marker. 11. The method of claim 10, further comprising the steps of: measuring a height of the tire placed on the transfer conveyor by a laser displacement sensor; andforwarding a measured value to a controller. 12. The method of claim 11, further comprising the step of controlling a position of the second camera by controlling a mover according to the measured value measured by the laser displacement sensor. 13. The method of claim 12, further comprising the steps of: capturing, with a second camera, data regarding a tread portion color line of the at least one tire placed on the transfer conveyor; andforwarding the data to the controller. 14. The method of claim 13, further comprising the steps of: analyzing the data; anddetermining a specification of the at least one tire based on the analysis of the data. 15. The method of claim 10, further comprising the step of displaying the orientation of the at least one tire. 16. The method of claim 14, further comprising the steps of comparing the tread portion color line to a reference color corresponding to a reference specification to determine the specification of the at least one tire, and displaying whether the color of the tread portion color line is substantially the same as the reference color. 17. The device of claim 1, wherein the surface is an outside wall of the tire. 18. The device of claim 1, wherein the balance marker is a sticker.
