- the green tire may be positioned at a predetermined position by expanding the diameter in synchronization with the tire radial direction.
- tire information including a green tire identification symbol is added to the information label.
- the identification symbol and the weight value of the green tire measured by the weighing scale may be recorded in association with each other.
- FIG. 1 is a schematic view showing a part of a tire molding facility 10 in which a green tire inspection device 20 according to an embodiment of the present invention is used
- FIG. 2 is a green tire inspection device.
- 20 is a front view
- FIG. 3 is a plan view of the green tire inspection apparatus 20.
- This tire molding apparatus 10 is a molding apparatus for molding an unvulcanized green tire T having a structure as illustrated in FIG. 4, and is, for example, on a rubber layer including an inner liner 1 and a chiefer 4.
- the carcass ply constituting the carcass layer 6 is laminated to form a cylindrical carcass node, and thereafter, the bead body 8 is set to the carcass band, turned up, etc., and then the cylindrical green case before shaving.
- the green tire T is molded by laminating rubber members constituting the belt layer 7 and the tread 2 and the like on the green case.
- the completed green tire T is moved to the take-out position with the inside of the bead body 8 supported by the drum D, released from being held by the drum D, and taken out.
- the take-out device 12 By being gripped from the outer periphery by the device 12, it is delivered to the take-out device 12.
- the green tire T passed to the take-out device 12 is rotated so that the central axis of the green tire T coincides with the vertical direction, it is transferred to the inspection device 20 by the conveying means 14, and then transferred to the table 50. Is taken out from the tire molding facility 10.
- the green tire inspection apparatus 20 includes a mounting table 30 supported by a weighing scale 22, and a mounting table 30 on which the green tire T is mounted.
- a green tire T mounted on the mounting surface 32 with a labeling device 24 disposed below the mounting surface 32.
- the bar code label as an information label is affixed to the side wall 3 of the green tire T.
- the mounting table 30 includes a supporting shaft 36, which is erected from a bottom plate 34 disposed on the measurement surface 22a of the weighing scale 22, and supports the mounting surface 32.
- the weight of the green tire T mounted on the mounting surface 32 is measured by the weigh scale 22 by the guide 28 fixed to the housing 26 of the 20 supporting the support shaft 36 slidably in the vertical direction. I am able to do that.
- the measured weight of the green tire T is transferred to the external data processor 16
- a through hole 38 is formed at a position corresponding to the inside of the bead body 8 of the green tire T, and a label sticking device 24 controlled by the data processing device 16 is disposed below the through hole 38.
- a barcode label is affixed to the sidewall 3 of the green tire T placed on the placement surface 32.
- Information including a tire identification symbol which is an identification symbol of the green tire T to which the label is attached, is given to the barcode label as tire information, and the tire identification symbol indicates the tire type, year of manufacture. Recorded in the database in the data processing device 16 in association with information related to the molding device that was molded, and in the database in association with the measured weight that is the measurement result of the weighing scale 22 described above. .
