Below, manufacture method and manufacturing installation about such toothbrush (brush) mainly illustrate the processing of bristle.
Making toothbrush (brush) at 10 o'clock, and at first, forming shank 11 and head 12, planting pore 16 planting to form on the hair side 15 thereafter by resin being carried out injection molded etc.Thereafter, unshowned in the drawings planting in portion's (planting operation), the pieces 17 of having tied up many bristles 13 is pressed into from central doubling is formed on the hole one by one of planting pore 16 of planting on the hair side 15, be fixed in by anchor 18 and plant in the pore 16, thus bristle 13 is planted hair on head 12.
Below, the toothbrush (brush) 10 before bristle 13 processing that form is like this dropped into bristle treating apparatus (bristle treatment process) 20 shown in Figure 4 one by one continuously.Bristle treating apparatus (bristle treatment process) 20 keeps and carries the delivery section (conveying operation) 26 of toothbrush (brush) 10 to constitute by pruning portion (pruning operation) the 21, the 1st～the 4th grind section (grinding step) 22～25 and at these each inter processes.
In pruning portion (pruning operation) 21, the tip that will just plant the bristle 13 of hair with cutter etc. trims precedent such as flat condition.The tip of having passed through the bristle 13 after such pruning portion (pruning operation) 21 becomes most advanced and sophisticated smooth and the shape at angle is arranged as shown in Figure 5.
Most advanced and sophisticated keep by delivery section 26 and be fed into the 1st grind section 22 by pruning portion (pruning operation) 21 bristles that trim 13.In the 1st grind section 22, use is ground abrasive particle and is formed for example abrasive roller of striated (spin finishing body) 31 on the surface of columnar cylinder, bristle 13 is ground.Abrasive roller 31 rotates (rotation) along the axle 31a of cylinder center on the side face direction, the bearing 31b rotation of supporting this central shaft 31a by order axle simultaneously makes abrasive roller 31 be rotation (revolution) on the direction of 360 ° of rotations at central shaft 31a.Make the bristle 13 of toothbrush (brush) 10 contact, carry out the grinding of bristle 13 with the abrasive roller 31 of rotation and revolution like this.
The grinding abrasive particle of the abrasive roller 31 of the 1st grind section 22 is wished granularity below #2000, preferably about #60～#800.If than the fine size of above-mentioned scope, then grinding efficiency significantly descends.In addition as if the coarse size than above-mentioned scope, the then roughness of machining surface of bristle, outward appearance and bad.Rotary speed is preferably rotation 200rpm～2500rpm, revolution 10rpm～500rpm.Rotation 500rpm～2000rpm more preferably, revolution 20rpm～250rpm.If get the speed faster than this scope, defectives such as burr or high-quality green tea fracture then appear.If get the speed slower than this scope in addition, then grinding efficiency significantly descends.
The amount of contact of abrasive roller 31 and bristle 13 preferably from the tip of bristle 13 to the root direction to the total length of bristle 13 80% till, be more preferably total length 70% till.According to such contact amount, can carry out taper processing from the deep of bristle 13, can make the toothbrush 10 of soft cone-shaped.On the other hand, if order more contacts with abrasive roller 31 to the bristle 13 in deep than above-mentioned scope, then might produce defectives such as the burr of bristle 13 or high-quality green tea fracture.
As shown in Figure 6, in the 1st grind section 22, bristle 13 most advanced and sophisticated and plant between mao portion (planting portion) and ground by interim, is removed the angle in pruning portion (pruning operation) 21 generations in 20%～70% scope of bristle total length.Carry out taper processing at tip portion then.At this moment, some burrs (バ リ) that produce during grinding remain in the surface of bristle 13.
Carried out toothbrush 10 after the thick taper processing of tip portion is transferred portion 26 and keeps and dropped into the 2nd grind section 23 by the 1st grind section 22.In the 2nd grind section 23, use abrasive roller (spin finishing body) 32 grind bristles 13, this abrasive roller 32 has formed a plurality of overshooting shapes on the surface of columnar cylinder 32a abrasive body promptly grinds projection 32b.
Abrasive roller 32 (spin finishing body) rotates (rotation) along the central shaft 32c of cylinder on the side face direction, the bearing 32d rotation of supporting this central shaft 32c by order axle simultaneously makes abrasive roller 32 be rotation (revolution) on the direction of 360 ° of rotations at central shaft 32c.Make the bristle 13 of toothbrush (brush) 10 contact, carry out the grinding of planting a mao portion (planting portion) of bristle 13 with the abrasive roller 32 of rotation and revolution like this.
The grinding projection 32b spacing each other of abrasive roller 32 that use, that be formed with a plurality of grinding projection 32b is preferably 0.5～10.0mm in the 2nd grind section 23 of having carried out with the 1st grind section 22 the thick taper processing back of the tip portion of bristle 13 being carried out.Be more preferably 1.0～6.0mm.If it is narrower to grind this scope of projection 32b gap ratio each other, the making difficulty of abrasive roller 32 then, cost increases.Otherwise if spacing is wide, then the contacting efficiency of bristle 13 and grinding projection 32b is poor, and increase process time.
And the granularity of formed grinding abrasive particle is below the #2000 on the surface of the grinding projection 32b of this moment, more preferably about #60～#800.If this scope of fineness ratio is thin, then grinding efficiency significantly descends.If this scope of fineness ratio is thick in addition, then the roughness of machining surface of bristle 13, outward appearance and bad.
The length of the grinding projection 32b of abrasive roller 32 is preferably 2.0mm～10.0mm, more preferably 3.0mm～8.0mm.Can carry out thus bristle 13 up to the attrition process in deep more.
The rugosity of grinding projection 32b is preferably 0.2mm～5.0mm, more preferably 0.5mm～3.0mm.If it is thicker than this scope to grind projection 32b, then the grinding projection 32b of abrasive roller 32 does not contact equably with the integral body of bristle 13, produces inhomogeneous in the taper attitude.Thinner if grind projection 32b in addition than this scope, the weakened of grinding projection 32b itself, the durability variation when then producing increases manufacturing cost.
The shape of grinding projection 32b can be any one in cylinder, polygon prism, circular cone, polygonal pyramid, the frustum of a cone, the polygonal pyramid platform.Rotary speed with abrasive roller 32 of so a plurality of grinding projection 32b is preferably rotation 300rpm～2000rpm, the scope of revolution 10rpm～300rpm.Be more preferably rotation 500rpm～1500rpm, revolution 20rpm～150rpm.
If rotation, the revolution speed of abrasive roller 32 are faster than above-mentioned velocity interval, then excessive to the pressure of bristle 13, produce burr or produce fracture at the tip of bristle 13.If get the speed slower than this scope in addition, then grinding efficiency significantly descends.The rotation of such abrasive roller 32, revolution speed be along with changing to the contact amount of bristle 13, if reduce then can be with the more speed spin finishing for the contact amount.Bristle 13 and the amount of contact of grinding projection 32b be preferably from the tip of bristle 13 to root side upward to the bristle total length 80% till, more preferably till 70%.If make grind projection 32b contact to bristle 13 than this scope deep more, then excessive and become the reason that produces burr to the pressure of bristle 13.
As shown in Figure 7, in the 2nd grind section 23, bristle 13 in 35～80% scope of bristle total length, interimly to most advanced and sophisticated and plant between mao portion (planting portion) and grind, makes the rugosity of bristle 13 reduce from planting a mao portion (planting portion) to abrading tip.In this stage, the some burrs that produce during grinding also remain on the surface of tip portion of bristle 13.
Be transferred portion 26 and keep and be fed into the 3rd grind section 24 planting the toothbrush 10 that has carried out more coarse taper processing between a mao portion (planting portion) and the tip by the 2nd grind section 23.In the 3rd grind section 24, use abrasive roller (spin finishing body) 33 grind bristles 13, this abrasive roller 33 promptly grinds projection 33b on the surface of columnar cylinder 33a with the abrasive body that set width forms a plurality of overshooting shapes off and on.
Abrasive roller (spin finishing body) 33 rotates (rotation) along the central shaft 33c of cylinder on the side face direction, the bearing 33d rotation of supporting this central shaft 33c by order axle simultaneously makes abrasive roller 33 be rotation (revolution) on the direction of 360 ° of rotations at central shaft 33c.The bristle 13 of toothbrush (brush) 10 is contacted with the abrasive roller 33 of rotation and revolution like this, carry out the grinding at the tip of bristle 13.
The grinding projection 33b spacing each other that forms off and on set width on the abrasive roller 33 of the 3rd grind section 24 is preferably 0.5mm～10.0mm.More preferably be 1.0mm～6.0mm.If its narrow, as then to grind projection 33b making difficulty of gap ratio, cost increases.Otherwise if spacing is wide, the contacting efficiency that then grinds projection 33b and bristle 13 is poor, and the time of the taper processing of bristle 13 increases.And the granularity of formed grinding abrasive particle is below the #2000 on the surface of grinding projection 33b, more preferably about #100～#800.If get the granularity thinner than this scope, then grinding efficiency significantly descends.If select the granularity thicker, the then roughness of machining surface of bristle 13, outward appearance and bad in addition than this scope.
The length of the grinding projection 33b of abrasive roller 33 is preferably 1.0mm～8.0mm, more preferably 2.0mm～6.0mm.Can carry out attrition process from the tip of bristle 13 thus.The rugosity of grinding projection 33b is preferably 0.5mm～4.0mm, more preferably 0.7mm～2.5mm.If get the grinding projection 33b thicker than this scope, then grind projection 33b and do not contact equably with the integral body of bristle 13, in the taper attitude of grinding projection 3 3b, produce inhomogeneous.If thinner than this scope in addition grinding projection 33b, the weakened of then grinding projection 33b itself, the durability variation when then producing increases manufacturing cost.
The shape of grinding projection 33b can be any one in cylinder, polygon prism, circular cone, polygonal pyramid, the frustum of a cone, the polygonal pyramid platform.The rotary speed of the abrasive roller 33 with a plurality of grinding projection 33b like this is preferably rotation 500rpm～2500rpm, revolution 10rpm～300rpm.Be more preferably rotation 1000rpm～2000rpm, revolution 20rpm～150rpm.
If speed is faster than above-mentioned velocity interval, then excessive to the pressure of bristle 13, bristle 13 produces burr or produces fracture at the tip of bristle 13.If speed is slower than this scope, then grinding efficiency significantly descends in addition.This rotary speed is along with changing to the contact amount of bristle 13, if reduce then can be with the more speed spin finishing for the contact amount.Bristle 13 and the amount of contact of grinding projection 33b are preferably 60%, more preferably 50% the position that begins from the tip of bristle 13 up to total length.Grind the darker deep of projection 33b contact if further make, then excessive and become the reason that produces burr to the pressure of bristle 13.In the 3rd grind section 24, the amount of contact that reduces bristle 13 interimly and grind projection 33b may make sharpizationer of high-quality green tea of bristle 13 thus.
As shown in Figure 8, in the 3rd grind section 24, bristle 13 in 5～60% scope of bristle total length, interimly most advanced and sophisticated and plant between mao portion (planting portion) and grind, makes the rugosity of bristle 13 reduce from planting a mao portion (planting portion) to abrading tip.In this stage, the some burrs that produce during grinding remain on the surface of tip portion of bristle 13.
The toothbrush 10 that has carried out more coarse taper processing in the tip region of bristle 13 by the 3rd grind section 24 is transferred portion's 26 maintenances and is fed into the 4th grind section 25.In the 4th grind section 25, use abrasive roller (spin finishing body) 34 to remove the burr of bristle 13 remained on surface, the surface of fine finishining bristle 13 and make it smooth, described abrasive roller 34 is equipped with the swing roller of fiber, the swing roller that has planted fiber and minute surface cylinder etc. by the surface and constitutes.Abrasive roller 34 (spin finishing body) rotates (rotation) along the central shaft 34a of cylinder on the side face direction, the bearing 34b rotation of supporting this central shaft 34a by order axle simultaneously makes abrasive roller 34 be rotation (revolution) on the direction of 360 ° of rotations at central shaft 34a.The bristle 13 of toothbrush (brush) 10 is contacted with the abrasive roller 34 of rotation and revolution like this, carry out the smooth grinding of bristle 13.
On the surface of abrasive roller 34 is under the situation of fiber, as preferred fiber, can list the chemical fibre of natural fibers such as cotton, fiber crops, silk, wool and polyurethane, polyamide, polyester, polyolefin, polypropylene, propylene etc.On the surface of abrasive roller 34 is under the situation of minute surface, and the surface is made of metal alloy such as stainless steel, titanium, aluminium, copper or pottery at least, but also is not limited to this.
The rotary speed of the abrasive roller 34 that such fine finishining is used is preferably rotation 500rpm～3000rpm, revolution 10rpm～500rpm.Be more preferably rotation 1000rpm～2500rpm, revolution 20rpm～250rpm.If speed is faster than above-mentioned scope, then produce the defectives such as fusion of the burr or the hair of bristle 13.If speed is slower than this scope, then burr is removed efficient and is significantly descended in addition.In addition, the amount of contact of the surface of abrasive roller 34 and bristle 13 is preferably from the tip of bristle to 50～80% of root direction bristle total length and contacts with the surface of abrasive roller 34.Like this, burr to the surface, coarse can be removed from the deep of bristle 13, good bristle shape can be accessed.
As shown in Figure 9, in the 4th grind section 25, the burr on the surface of bristle 13 is removed, and wears into taper with the deep from bristle 13 to the mode lappingout that the tip reduces the rugosity of bristle 13 smoothly.
Behind such smooth grinding, further can carry out the pruning of bristle tips part.And then, as subsequent handling, taper can be processed in the bristle tips zone.
Manufacture method and manufacturing installation according to the brush that describes in detail above, the burr on bristle 13 surfaces is removed, grind to make to reduce smoothly to the rugosity of tip bristles 13, form more than one at least flex point to portion's of planting (root) direction from the tip of bristle 13 from the deep of bristle 13.Then, the surface roughness Ra of these bristles 13 forms less than 0.5 μ m, prevents that damage is by sweeping face.And, after on the head 12 that this bristle is planted at brush 10, bristle 13 is trimmed to shape arbitrarily, afterwards, carry out sharpization, the taper processing of the high-quality green tea end of bristle 13, can on the pointed shape of bristle 13, add various variation thus, can carry out design, the manufacturing of the functional higher brush after sharpization of high-quality green tea of bristle 13.
Planting before the hair to handle and make under the situation of sharpization of bristle high-quality green tea in the past by medicine, the influence of factors such as volume pressure that most advanced and sophisticated cone-shaped is subjected to treatment temperature, time, tie up the band of bundle bristle tuft, the control of the formation of cone-shaped is very difficult.And because utilize capillarity that medicine is drawn into bristle tuft, at the high-quality green tea two ends adequate relief of planting the Mao Qiancong bristle tuft into a cone shape, so short more as the total length of the bristle tuft of processing object, the control of the cone-shaped at high-quality green tea two ends is difficult more.But, according to the manufacture method and the manufacturing installation of above-mentioned brush, can freely control the cone-shaped of bristle, and also can be simply and promptly make sharpization of high-quality green tea of bristle 13 for the short bristle of total length.
And, in order after planting hair, to carry out sharpization of bristle 13, be not limited to anchor and plant hair, also can plant in the hair at the no anchor that mold formed and hot melt graft hair etc., make the brush of bristle 13 with sharp cone-shaped.
And, before planting bristle like that, make under the situation of sharpization of high-quality green tea by the medicine processing in the past, its yield rate generally is lower than 50%, and only utilize capillarity to carry out under the situation by medicine processing carrying out sharpization processing, therefore have limitation at aspects such as the formation of cone-shaped, sharpization speed, operation needs a lot of times.But, according to the manufacture method and the manufacturing installation of brush of the present invention, after bristle 13 planted hair and pruning, carry out sharpization processing, so productivity increasing substantially by grinding step, yield rate also improves.
And in the manufacture method and manufacturing installation of general in the past brush, bristle tuft after the sharpization processing is unstable and easily be scattered the extremely difficult feather planting machine that supplies to automatically of the bristle tuft after this sharpization processing.But, by as the manufacture method of brush of the present invention and manufacturing installation, after planting hair, carrying out sharpization processing, the automatic supply of bristle 13 becomes easy, and do not produce the most advanced and sophisticated uneven situation that produces defective work that in the past can not avoid owing to bristle, therefore do not need the operation of biochemical (correction) again, the man-hour in the time of can suppressing the brush manufacturing significantly.
And planting in mao operation of in the past bristle, when the bristle that tapered shape sharp changed was planted mao, the situation that the bristle that this speed of production has to compare not sharpization processing is planted hair was low.But, according to the manufacture method and the manufacturing installation of brush of the present invention, plant mao operation and use the not bristle of sharpization processing, therefore can not reduce and plant hair quality and use common apparatus to realize planting at a high speed hair.
And, can not reduce the bristle quality and be easy to plant multiple bristle (color/bristle diameter etc.).Therefore, can be with the wider brush of the variation of more low-cost manufacturing bristle.And owing to do not need special-purpose feather planting machine, increase and decrease that therefore can be according to demand and handling neatly can be made brush with low cost.
And, the brush of making by mechanical lapping in the past, because of the bristle wearing and tearing, bristle surface is coarse, burr is a lot, consequently as under the situation of toothbrush, might injure the grade oral cavity in by sweeping face.But, manufacture method and manufacturing installation according to brush of the present invention, undertaken after grinding of bristle surface cut by mechanical lapping, surface grinding gets very smooth in finishing step, the machining accuracy on surface is good, consequently can provide to enter the gap easily and safe toothbrush when using as toothbrush.
In addition, bristle 13 of the present invention can be any material, preferably enumerates the bristle that is formed by polyamide (6-10 nylon, 6-12 nylon etc.) and mylar (PET, PBT, PTT etc.).
And, the shape of the bristle after grinding in the manufacture method of brush of the present invention and the manufacturing installation is except shown in above-mentioned embodiment, grinding the deep that makes from bristle reduces smoothly to the rugosity of tip bristles, also can shown in for example Figure 10 A～10D, grind to form the bristle of various cross sectional shapes.The grinding shape of these each bristles can realize by shape and rotary speed, the direction of rotation of control abrasive roller.By according to the grinding shape that is changed bristle by the shape of sweeping face like this, can produce according to the brush of being brought into play best sweeping ability by the sweeping thing.
And, make under the situation of toothbrush in the manufacture method of for example using brush of the present invention and manufacturing installation, except shown in above-mentioned embodiment will plant the global shape at the tip of the bristle tuft of head make smooth, also for example shown in Figure 11 A～11D, make and have concavo-convex shape.Thus, can give distinctive sweeping ability to various toothbrushes.

According to the result shown in the table 1,, all be good to the contiguous sense and the overall merit of gum for the toothbrush of making by any embodiment.And for the toothbrushes by embodiment 1,4,6 and 7 manufacturings, the between cog entering is also good.Relative therewith, the between cog entering and the overall merit of the toothbrush of being made by comparative example 1～4 are not good.And comparative example 1,2 and 4 the contiguous sense to gum are not good yet.
According to the present invention, after bristle being planted the head of hair, bristle is trimmed to shape arbitrarily at brush, afterwards, carry out sharpization and the taper processing of the high-quality green tea of bristle, can can design, make the functional high brush of most advanced and sophisticated sharpization of bristle to the additional multiple variation of the pointed shape of bristle thus.
And, can freely control the cone-shaped of bristle, and also can be simply and promptly make sharpization of high-quality green tea of bristle for the short bristle of total length.
And, in order after planting hair, to carry out sharpization of bristle, be not limited to anchor and plant hair, mold formed and hot melt graft the hair etc. no anchor plant in the hair, also can make the brush of bristle with sharp cone-shaped.
And, after bristle planted hair and pruning, carry out sharpization processing, so productivity increasing substantially by grinding step, yield rate also improves.
And owing to be to carry out sharpization processing after planting hair, the automatic supply of bristle becomes easily, and can therefore not need biochemical (correction) again operation, the man-hour in the time of can suppressing the brush manufacturing significantly owing to the most advanced and sophisticated uneven defective work that produces of bristle.
And,, therefore can not reduce and plant hair quality and use common apparatus to realize that high speed plants hair because it is identical with the common mao operation of planting to plant mao operation.
And, can not reduce the bristle quality and be easy to plant multiple class bristle (color, bristle diameter etc.).Therefore, can be with the wider brush of the variation of more low-cost manufacturing bristle.And owing to do not need special-purpose feather planting machine, increase and decrease that therefore can be according to demand and handling neatly can be made brush with low cost.
