Abstract

PURPOSE:To measure tire width accurately in a short period of time. CONSTITUTION:Two pieces of mobile reflectors 6a, 6b set on one side part of a conveyor 2 are lifted up and down by a lifting device 4 vertically orthogal with a tire conveyance direction X while counting lifting position against a tire W conveyed on a conveyor 2 and reflected to a reflector 10 set on the other side part of the conveyor 2 by way of reflecting an optical axis Q projected from optical detectors 9a, 9b provided with light projection and reception functions under it to the mobile reflectors 6a, 6b. The mobile reflectors 6a, 6b lift up and down back and forth between an upper limit proximity switch SW1 and a lower limit proximity switch SW2 by the lifting device 4, and when the conveyed tire W shields an optical axis Qa, position of the mobile reflectors 6a, 6b at this time of shielding is detected by an encoder 5. This value is processed by a centralized processing unit and tire width is measured.
