PURPOSE:To make it possible to simply change over the rotary speed of a bottle transfer disc, in transmitting the rotation of a drive shaft to the transfer disc, by fixing a connection ring body to the upper position of a rotary shaft to directly trasmit the rotation of the drive shaft and fixing the same to the lower position of said rotary shaft to transmit the rotation of said drive shaft at a reduced speed. CONSTITUTION:In driving a bottle transfer disc 1 for a large bottle, the bolt 18 of a connection ring body 17 is threaded with the screw hole 15b of a bearing holder 15 to fix said ring body 17 to the upper position side of a rotary shaft 4 while the lower side engaging projection 17b of the connection ring body 17 is engaged with the groove 22a to be engaged with the connection disc 22 integrally formed to the connection shaft part 11b of a drive shaft 11, and the rotation of the drive shaft 11 is transmitted to the rotary shaft 4 in a ratio of 1:1. In the case of the disc 1 for a small bottle, the bolt 18 of the ring body 17 is threated with the screw hole 15c of the holder 15 to fix the ring body 17 to the lower position side of the rotary shaft 4 and the projection 17b of the ring body 17 is brought into engagement with the connection disc 27 cooperated with a reduction gear mechanism 24 to transmit reduced speed rotation to the rotary shaft 4. By this mechanism, the inspection efficiency of different kind of bottles can be enhanced. |
