The shaft end supported by 71c and protruding from the bearing member 71a is connected via a coupling 75 to a drive shaft 74 protruding from the bearing member 73 of the drive motor 72.

Like the brush roller 61, the brush roller 81 is also constructed of horse hair or resin bristles on its outer peripheral surface, and its rotation axis is attached to a base 83, as shown in FIG. A pulley 85 is bonded to the end of a rotary shaft that is supported by a pair of bearing members 84 and protrudes from one of the bearing members 84 . A belt 88 is wound around this pulley 85 and a pulley 87 attached to a drive shaft of a drive motor 86.
Although only one brush roller 81 is provided in this embodiment, a plurality of brush rollers 81 may be provided in series along the outer periphery of the rotary disk 4 and each may be rotated by a separate drive motor. Although the upper surface of the portion 2a is slidably contacted, the lower surface may be similarly slidably contacted.

Next, the operation of the above embodiment will be explained.

When the drive shaft 3 is rotated by a motor (not shown), the rotary disks 4, 48 and star wheels 5, 6 are rotated in forward and reverse directions, respectively. Also, due to the rotation of the star wheels 5 and 6, the wheel shafts 14 and 1
The V-belt 24 wound around the pulleys 19, 20 and the pulley 23 attached to the rotary disk 4 also rotates, and the pedestal 12, which is sequentially moved together with the rotary disk 4 and comes into contact with the belt 24, is rotated. Ru.

On the other hand, when the rotation shaft 35 of the supply roller 37 is rotated by the motor connected via the V-belt 43, the intermediate roller 36 is rotated in the opposite direction to the supply roller 37 via the gears 40 and 41, and the coating roller 28 is rotated in the opposite direction to the supply roller 37. Rotating disk 4 via V belt 39
The motors 72 and 86 are rotated in the same direction as the
When the brush rollers 61 and 81 are driven, the brush rollers 61 and 81 are rotated.

In the above, the bottles 2 sent through the conveyor path 1 by the conveyor 1' are separated from each other by the required time by the inlet star wheel 5 and the guide frame 7, as shown in FIG. Bottle holder 1
2 through the plate 13, during which the bottle body 2a is brought into contact by the rotating wheel 5 between the teeth 5' of said wheel 5 in its recess 5'' and against the elastic friction material 9. It moves while rotating.
After that, the lifting rod 50 is pushed down by the cam part 57, and the head 49 holds the upper part of the bottle 2, so that the upper part of the bottle 2 and the lower part are connected to the head 49 and the pedestal 1.
2 is completely retained.

Next, when the bottle 2 held as described above advances to the position of the brush roller 61, the pulley 11 of the pedestal 12
comes into contact with the V-belt 24, the bottle 2 rotates several times, and during this period, the rotating brush roller 61 removes the condensed water adhering to the lower surface of the body 2a over the entire circumference. removed. On this occasion,
Since the brush roller 61 driven by a single motor 72 removes the condensed water over a relatively long distance, that is, over a plurality of bottles 2, there is almost no unevenness in removal.

Next, when the bottle 2 advances to the coating section C, the body section 2a comes into sliding contact with the coating section 28a of the coating roller 28, and is supplied from the coating section 28a to the coating roller 28 via the nozzle, the supply roller 37, and the intermediate roller 36. The coating liquid is applied to the scratches generated on the upper and lower parts of the body 2a. Since the bottle 2 rotates on its own axis due to frictional contact with the coating roller 28, this application is performed evenly over the entire circumference. Furthermore, if uneven coating occurs during coating, it can be adjusted by changing the attachment position of the tip of the arm 31 to the coating roller 28 and adjusting the eccentricity e.

When the bottle 2 further advances to the position of the brush roller 81, the bottle 2 is moved to the position where the pulley 11 of the pedestal 12 is
Since it comes into contact with the belt 24, it rotates several times, and during this period, the rotating brush roller 81 polishes the upper surface of the body 2a coated with the coating liquid. That is, the upper surface coated with the coating liquid normally contains moisture and has fine irregularities, but the brush roller 81
By polishing, the coating liquid is rubbed in and the water is removed, resulting in a smooth surface all around the coated surface.

After finishing the surface, the bottles 2 are moved from the pedestal 12 of the rotary disk 4 to the transfer path 1 via the crossing plate 13 by the outlet star wheel 6 and the guide frame 8, with the distance between the bottles being the same as described above. separated and discharged.

The scratches generated on the bodies 2a of the large quantity of bottles conveyed on the conveyor 1' as described above are continuously coated to cover the entire circumference.

This invention is as described above, and it is possible to quickly and effectively apply the coating to a large number of worn bottles.
Scratches that occur on the surface of the bottle body can be covered all around, but during the application, the first rotating brush roller reliably removes the condensed water that adheres to the lower surface of the bottle body. To obtain a high-quality scratch-proof bottle by polishing the surface of the bottle body after coating with a second rotating brush roller to make the coated surface smooth. I can do it. In addition, the first and second rotating brush rollers, which rotate sideways to the coating surface of the bottle body, remove condensed water and polish as described above, making high-speed operation possible. It has excellent effects such as being able to synchronize with
