分ける方法も提案されている。(Conventional technology) A tire manufacturing factory has tens to hundreds of tire vulcanizers installed, and various tires with different specifications (size, tread pattern, number of plies, usage conditions, etc.) are being processed in parallel. vulcanized. In that case, when the tires are cured, the vulcanized tires are sorted by specification based on the rod number that is transferred from the mold to the tire, or the vulcanized tires sent out from each tire vulcanizer are stored in dedicated racks. and store them according to their specifications. In addition, as shown in Figures 2 and 3, in the unvulcanized stage, multiple stripes of color paint G are applied in the circumferential direction on the outer peripheral surface of the tire G (usually applied at the tread extrusion line stage), or magnetic tape is applied. A method has also been proposed in which vulcanized tires are sorted by specification by pasting them on tires and detecting the same color paint C or magnetic tape after vulcanization.

を生じるという問題があつた。(Problems to be Solved by the Invention) When applying multiple stripes of color paint C in the circumferential direction on the outer circumferential surface of the tire G in the unvulcanized stage as described above, a tread pattern is formed on the outer circumferential surface of the tire. When molding, color paint C is applied to the rubber from the air vent hole.
The color paint C flows out onto the surface and becomes scattered, causing problems in detection after vulcanization. In addition, when attaching magnetic tape to the outer circumferential surface of a tire, if the base of the magnetic tape is made of rubber, it will break or deform during vulcanization, and if the base is made of a material that does not easily deform during vulcanization, Since this will have a negative effect on the engraving pattern and the lifespan of the tire, it is unavoidable for the operator to distinguish them and sort them according to specifications as described above. However, in that case, there were problems in that work efficiency was poor and discrimination errors occurred.

との比較が行われる。 Next, the operation of the vulcanized tire specification number discriminating device will be specifically explained. Paint (color paint)
is applied in multiple strips in the circumferential direction on the outer circumferential surface of an unvulcanized tire, and the specification number for each tire is displayed.Then, it is vulcanized, and the vulcanized tire T with the same multiple strips of paint dotted thereon is transported. The conveyor 1 transports the vulcanized tire to below the specification number discriminating device and stops. Next, each shoe 5 and detector 6 whose diameter is reduced
is lowered, and the detector 6 comes into contact with the sidewall portion T2 of the vulcanized tire T. At this time, the lowering of each shoe 5 and detector 6 is stopped. The detection signal from the detector 6 is then sent to the control device to calculate the tire width. Then each show 5
moves inward in the radial direction, and the claws 5 of each shoe 5
1 grabs the bead portion T 3 of the vulcanized tire T, and then each shoe 5 and detector 6 rise to lift the vulcanized tire T. When the center of the vulcanized tire T is lifted up to a predetermined height based on the above calculation results, each shoe 5 and detector 6 stop, and then the bracket 7 moves radially inward and the optical sensor ( Color sensor) 8 approaches the outer peripheral surface T1 of the tread portion of the vulcanized tire T. When the rod 9 comes into contact with the surface T1 of the vulcanized tire T and the detector provided on the rod 9 is activated, the bracket 7 stops, the rod 9 moves radially outward, and the vulcanized tire T is activated. Tread part outer circumferential surface of finished tire T 1
The vulcanized tire T is then rotated through each shoe 5, and an optical sensor (color sensor) detects the presence or absence of scattered paint (color paint) and its color.
8. When the optical sensor (color sensor) 8 completes the detection, each shoe 5 descends, the claws 51 provided on each shoe 5 release the vulcanized tire T, and the vulcanized tire T is transported. Placed on the conveyor 1, each shoe 5 is then raised. At this time, the detection signal from the optical sensor (color sensor) 8 is converted into specification data of the vulcanized tire T, and displayed on the control device. A comparison is made.
