Abstract

A marking device of the present invention includes a sequence of two belt conveyers for conveying a tire after undergoing a test by a tire testing machine, a pair of laser sensors each installed in a predetermined position in a conveyance direction of the tire by the belt conveyer, and adapted to detect an edge of the tire, and a controller for controlling a motor for driving the belt conveyer based on an output from the laser sensor. The controller is operable to convey the tire by a conveyance distance calculated based on a distance from an installing position of the laser sensor to a print position, an outer diameter of the tire and a predetermined mark position when the edge of the tire is detected by the laser sensor, and then to stop the tire, whereby the mark position of the tire is aligned with the print position.

First claim

What is claimed is:

1 . A marking device installed side by side with respect to a tire testing machine for testing a tire, the marking device comprising:
a marking head for printing a mark in a mark position on the tire after undergoing the test by the tire testing machine, the mark being based on a result of the test performed by the tire testing machine; a sequence of a plurality of tire conveyance devices for conveying the tire after undergoing the test by the tire testing machine to the marking head; a tire detector installed in a position in a width direction of the tire perpendicular to a conveyance direction of the tire by the sequence of the tire conveyance devices so as not to interrupt the tire, the tire detector being adapted to detect the tire conveyed to the marking device after the test by the tire testing machine; and a control unit for controlling the sequence of the tire conveyance devices based on a distance from an installing position of the tire detector to a print position and information on the tire in a radial direction thereof in such a manner that the tire is stopped with the mark position aligned with the print position.

2 . The marking device according to claim 1 ,
wherein the tire detector is installed at the tire conveyance device passing through the marking head among the sequence of the tire conveyance devices.

3 . The marking device according to claim 1 ,
wherein the tire detector is installed in the print position in the conveyance direction of the tire by the sequence of the tire conveyance devices.

4 . The marking device according to claim 1 ,
wherein the tire detector is installed in a position on an upstream side with respect to the print position in the conveyance direction of the tire by the sequence of the tire conveyance devices, and wherein the control unit is adapted to decrease a conveyance speed of the tire after the tire detector detects the tire.

5 . The marking device according to claim 1 ,
wherein the tire conveyance device is a belt conveyer.

6 . The marking device according to claim 1 ,
wherein the tire detector is a laser sensor.

7 . The marking device according to claim 6 ,
wherein the tire detector is installed to have a scanning direction thereof forming an angle with respect to a tire conveyance surface.
