Description

  The present invention relates to a flocking device.

In general, a toothbrush is produced by sequentially planting a hair bundle of hairs in a plurality of flock holes provided on a flocked surface of a head portion. As a hair bundle flocking device, for example, a flocking device is known in which a hair bundle for bristles is folded in half, a pinning tool called a flat wire is sandwiched between them and driven into a flocking hole of a brush to plant the hair bundle. (For example, Patent Document 1). Such a flocking device includes a flocking machine for flocking hair bundles and a hair conveying machine for supplying hair to the flocking machine. The flocking machine includes a flocking head that is moved and moved in a direction that allows contact with and away from the flocking hole of the head portion of the toothbrush, and drives the bristled bunch into a flocking hole together with a flat line. A hair bundle supplying means for supplying the hair and a flat wire supplying means for supplying a flat wire to the flocking head are used. As a hair conveying machine, a storage part such as a so-called hair dish that stores a hair group composed of a plurality of hairs, and a pusher that pushes the hair group of the storage part from its rear end toward the hair transplanter; The thing provided with, is used.
In the said hair transplantation apparatus, while picking up the hair bundle of a predetermined number from the hair group of the storage part by the picker by which the hair scraping groove | channel was formed in the outer periphery part, the scraped hair bundle is supplied to the hair transplant head.

  On the other hand, hair used for flocking tends to generate static electricity during the manufacturing process. Therefore, for the purpose of suppressing a reduction in handleability of the hair due to static electricity, the hair is subjected to an oil treatment in which a lubricant is applied to the surface thereof. However, if there is a portion where the amount of lubricant applied is large in the hair group of the reservoir, the hair in that portion may become sticky, or the hair may be closely adhered to form a lump. In this case, scraping of the hair bundle by the picker is partly difficult, the number of hair bundles supplied to the flocking head is temporarily reduced, and the number of hair bundles to be flocked to the brush head is uneven. The quality of the product may deteriorate.

'I will be loosened. Thereby, even when the hairs of the hair group B ′ are closely adhered to each other by the lubricating oil to form a lump, the lump of the hair is loosened and eliminated. Therefore, a predetermined number of hair bundles B can be stably scraped from the hair group B ′ stored in the storage section 50 by the hair scraping groove 31a of the picker 31.

The sliding portion 70 only needs to be such that the contact surface slides the hair tip b of the hair group B ′ in the direction of supplying the hair, and in this example, the hair tip b of the hair group B ′. Is a belt conveyor that rotates so that the hair surface b of the hair group B ′ slides in the hair supply direction.
The material of the belt of a belt conveyor can use the same material as a general belt conveyor, and an elastomer and a silicon | silicone are preferable on hygiene.
The driving method of the belt conveyor is not particularly limited, and general use such as an electric motor type can be applied.
However, the sliding portion 70 is not limited to the belt conveyor, and for example, the contact surface with the hair tip b of the hair group B ′ moves the hair tip b of the hair group B ′ in the supply direction of the hair. A sliding roller or the like may be used.

The width of the contact surface of the sliding portion 70 with the hair group B ′ (belt width of the belt conveyor) is preferably equal to the width of the concave strip 51 of the storage portion 50.
The length _{d 1} of the contact surface with the use bristle group B 'of the sliding portion 70 (the length of the belt conveyor, to FIG. 3 (B)) is preferably from 15～100Mm, 30 to 50 mm is more preferable.

The sliding portion 70 has an end portion on the side of the hair transplanter 2 that is closer to the end portion on the side of the hair transplanter 2 of the hair group B ′ (in this embodiment, the end portion on the side of the hair transplanter 2 of the concave strip 51). It is preferable that it is located on the 2 side.
If the sliding part 70 is arranged in this way, the contact surface of the sliding part 70 with the bristle tip b also slides the bristle tip b located in the bristle scraping groove 31a of the picker 31. . As a result, the hair is scraped by the hair scraping groove 31a more quickly while being loosened by the sliding portion 70.

The distance d ₂ (FIG. 3 (B)) between the end of the sliding portion 70 on the side of the hair transplanter 2 and the end of the hair group B ′ on the side of the hair transplanter 2 is the hair group B ′ (hair bundle B ) Is preferably 1/30 to 1/3 times, more preferably 1/15 to 1/5. If the distance d ₂ 1/30 times or more with respect to the length of use hair, can be supplied to use bristle scraping grooves 31a to use the hair more stably. Also, the long distance d ₂ 1/3 times or less the length of use hair, use hair use hair group B 'is excessively pulled out to planting machine 2 side by the sliding portion 70, use hair It is easy to suppress loss without being supplied to the scraping groove 31a.
The length of the hair is preferably 20-50 mm.

Further, as shown in FIG. 3A, the sliding portion 70 reciprocates in the hair axis direction of the hair group B ′ (up and down movement in the present embodiment), and the hair tip b of the hair group B ′. It is preferable to contact intermittently. That is, it is preferable that the sliding portion 70 has a hair tapping function of tapping the hair tip b of the hair group B ′.
In the hair group B ′ of the reservoir 50, the hair may jump out in some places due to vibration or the like, and the hair ends of the hair group B ′ may be distorted and may not be aligned. By reciprocating the sliding portion 70 in the direction of the hair axis and hitting the hair tip b of the hair group B ′, the hair that has jumped out of the hair group B ′ (the hair β in FIG. 3A) is obtained. The hair ends b can be aligned by returning to the hair group B ′. Thereby, the good quality products (toothbrush etc.) by which the hair | bristle bundle B with which the bristles arranged were planted can be manufactured more stably.

  The amplitude of reciprocation along the hair axis direction of the hair group B 'for the sliding portion 70 is preferably 0.5 to 10 mm, and more preferably 1 to 5 mm. If the amplitude of the reciprocating motion of the sliding part 70 is 0.5 mm or more, it is easy to align the hair tips b of the hair group B ′. If the amplitude of the reciprocating motion of the sliding part 70 is 10 mm or less, the effect of loosening the hair group B ′ by the sliding part 70 can be easily obtained, and the hair bundle B can be supplied more stably.

  The reciprocating movement of the sliding portion 70 may be performed by using a drive unit 71 that can reciprocate the sliding portion 70 in the direction of the hair axis of the hair of the hair group B ′. The drive unit 71 is not particularly limited, and examples thereof include a motor and a vibration air valve.

Hereinafter, the effect | action of the hair transplantation apparatus 1 is demonstrated.
First, in the bristle carrier 3, as shown in FIGS. 1-3, the bristle group B 'by which the several bristle was arranged upright was stored in the concave strip 51 of the storage part 50, and the extrusion part 60, the hair group B ′ is pushed toward the hair transplanter 2 in a direction perpendicular to the hair axis direction of the hair. Further, on the side of the hair transplanter 2 of the storage unit 50, the contact surface with the hair tip b of the sliding portion 70 (belt conveyor) disposed in contact with the hair tip b of the hair group B ′ is the hair group B. The hair tip b for 'is slid in the direction of supplying the hair. The contact surface of the sliding portion 70 slides on the hair tip b of the hair group B ′, so that even if the hairs are in close contact with each other by a lubricant, the hair group B ′ The hair is loosened and supplied to the hair transplanter 2 stably.
The sliding speed of the contact surface of the sliding portion 70 (belt speed of the belt conveyor) is preferably 25 to 250 mm / min. If the said speed | rate is 25 mm / min or more, the effect which loosens hair group B 'with the sliding part 70 will be fully easy to be acquired. If the said speed is 250 mm / min or less, it will be easy to suppress that the hair | bristle tip of the hair group B 'is disturbed.

  Further, the sliding portion 70 reciprocates in the direction of the hair axis of the hair, and strikes the surface (upper surface) of the hair group B 'on the hair tip b side at a constant cycle. As a result, the hair that has jumped out in some places due to vibration or the like is returned to the hair group B ', and the ends of the hair group B' are aligned. Then, the hair bundle B to be planted is supplied to the picker 31 with its hair tips aligned.

  Next, in the hair bundle supply means 30 of the hair transplanter 2, the picker 31 rotates around the support shaft 31 b to scrape a predetermined number of hair bundles B from the hair group B ′ of the storage unit 50 and the hair transplantation head. The hair bundle B that has entered the 20 slits 23 and scraped off is supplied to the hair bundle guide groove 24. Further, the flat wire supply means 40 supplies the belt-like flat wire H ′ to the flocking head 20, cuts the tip thereof to a predetermined length with a cutter, and supplies the flat wire H cut into the flat wire guide groove 25. To do.

On the other hand, the brush handle 101 is held by the chuck mechanism 12 of the brush holding means 10, and the head portion 102 is fixed by the fixture 11.
The flocking head 20 to which the hair bundle B and the flat wire H are supplied moves in a direction approaching the flocking surface 102a of the head portion 102. And the front-end | tip part 20a of the flocking head 20 is faced | matched with the flocking surface 102a of the head part 102, and the hair | bristle bundle B is sent out in the direction corresponded with the axis line of the flocking hole 103 from the state. That is, the flocking needle 21 moves in the flocking needle guide groove 22 toward the distal end portion 20a and presses the flat wire H supplied to the flat wire guide groove 25 by the flocking needle 21 together with the flat wire H. Then, the hair bundle B supplied to the hair bundle guide groove 24 is sent out to the distal end portion 20a of the flocking head 20. The hair bundle B sent out from the tip 20a of the flocking head 20 is folded in half by a flat wire H, and is driven into the flocked hole 103 together with the flat wire H sandwiched therebetween to plant the hair.
After the flocking, the flocking head 20 moves backward in a direction away from the head portion 102. Thereby, the hair | bristle bundle B is extracted from the front-end | tip part 20a of the flocking head 20, and returns to the position before flocking again.
The flocking device 1 performs such a series of flocking operations a plurality of times while changing the position of the head unit 102, and sequentially flocks the hair bundle B into the plurality of flocking holes 103 provided in the head unit 102.

The hair transplanting apparatus 1 described above can stably supply a predetermined number of hair bundles B from the hair conveying machine 3 to the hair transplanting machine 2, and can uniformly plant the hair bundles B on the brush. The said effect in the hair transplanting apparatus 1 originates in the bristle carrier 3 being equipped with the sliding part 70. FIG.
The extruding unit 60 presses with the same force whether the number of hairs in the hair group B ′ is large or small. Therefore, only in the extrusion part 60, when the hair is sticky with a lubricant or when a lump is formed in close contact with the surrounding hair, the hair can be scraped off from that portion of the hair group B ′. It becomes difficult temporarily, and the number of hair bundles scraped off by the hair scraping grooves 31a may become uneven. On the other hand, in the flocking device 1, the hair group B ′ is loosened by sliding the sliding part 70 while pushing the hair group B ′ of the storage part 50 by the pushing part 60. That is, the hair group B ′ is supplied toward the hair transplanter 2 while being loosened by the sliding portion 70. As a result, even if the hair of the hair group B ′ is sticky with a lubricant, or the surrounding hairs closely adhere to each other to form a lump, the loosened hair quickly enters the hair scraping groove 31a. Since the scrapes are scraped off, a predetermined number of hair bundles B are stably supplied to the hair transplanter 2. Therefore, the number of hair bundles B to be planted becomes uniform, and a brush product with good quality can be obtained. In addition, by hitting the hair tips of the hair group with the sliding portion, the hair bundle is supplied to the hair transplanter in a state where the hair tips are aligned, so that a good product can be obtained.

In addition, this invention is not limited to the flocking apparatus 1 used for manufacture of the toothbrush 100 mentioned above. For example, the sliding portion may not reciprocate in the direction of the hair axis of the hair group, and may not have the function of tapping the hair tip of the hair group of the storage portion.
Moreover, if the hair conveying machine is provided with the sliding part mentioned above, it will not be limited to the hair transplantation apparatus 1, It can apply widely to the hair transplantation apparatus which drives a hair bundle into a flocking hole with a flat line, and implants. Further, the present invention is not limited to a flocking apparatus that implants hair by driving a hair bundle into a flocking hole together with a flat line, and can also be applied to a flocking apparatus that includes a flocking machine for flocking by other methods.
