- the handle clamp 29 chucks the brush handle 14 delivered from the above-mentioned brushless / handle supply device with its tip end downward and moves it up and down.
- radial blades 1 are manufactured from hair bundles 4 at the blade manufacturing position.
- the manufacturing method is substantially the same as the method described above.
- the welding head 5 descends and the bossed Radial blades 1 are manufactured.
- the rotary table 25 and the bristle bundle penetrating the processing bed 6 are once pulled down to the lowering point indicated by 4B.
- the rotary table 25 rotates until the processing bed 6 moves to the blade stacking position.
- the manufactured radial blade 1 remains on the processing bed 6, and the boss portion (annular projection 3) formed on the lower surface of the welded portion 2 is used for positioning and fixing the radial blade 1 and improving stability. Contribute.
- the brush handle 14 When a predetermined number of radial blades 1 are fitted into the brush handle 14 at the blade stacking position at the blade manufacturing position, the brush handle 14 is transferred to the radial blade fixing device (FIG. 18). Specifically, the brush handle 14 is passed to the lifting chuck 30 of the fixing device. The lifting chuck 30 holds the brush nozzle 14 with the radial blades 1 mounted thereon, with the tip thereof down, and is driven up and down by a cylinder 31. A welding table 32 is provided beside the cylinder 31, and a welding machine 15 is mounted on the welding table 32.
- Root 1 is fixed.
- a 360-degree toothbrush having a cylindrical brush head at the tip end on which a predetermined number of radial blades 1 are stacked is manufactured with high efficiency in a fully automatic manner.
- the cylindrical brush head formed by laminating a predetermined number of radial blades 1 can be integrated into a boss by welding the inner peripheral surface. If this boss-type integrated cylindrical brush head is configured to be inserted into the tip of the brush handle, a head-replaceable 360-degree toothbrush is constructed.
- An antibacterial toothbrush is formed by manufacturing a radial blade by kneading an abrasive material having an antibacterial action into a thread material.
- the boss-type integrated cylindrical brush head has extremely high strength.
- the results of the tensile test are shown in Table 1 in comparison with the normal flocking type rotary brush and the radial blade with boss. Radial blades with bosses are also sufficiently strong, but boss-type integrated cylindrical brush heads are even stronger.
- the lower limit of the tensile test of the implanted toothbrush is defined as 8 N or more from the JIS ⁇ ISO ⁇ standard. (Reference) Brief description of drawings
