Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head unit for fixing and holding a wig base in a wig planting machine for automatically implanting hair on a wig base.

[Conventional technology]

Generally, when hair made of human hair and / or artificial hair is implanted on a wig base, a portion of the wig, such as a frontal portion, a parietal portion, a temporal region, and an occipital region, is used in order to realize a natural hair volume and flow. It is necessary to perform the flocking operation while appropriately mixing several types of flocking methods according to the conditions.

As such a flocking method, typically, a method such as V-planting, single-planting, bread-single-planting, or insertion-planting is known.

By the way, conventionally, the hair transplanting operation of the wig has been performed manually one by one according to these hair transplanting methods. However, this manual flocking operation is heavy labor and requires a high level of skill, so that one wig is required. Even a skilled technician takes a long time of about 10 to 20 days to finish a wig.

For this reason, as disclosed in, for example, JP-A-59-36707 to JP-A-59-36711 by the present applicant, a new wig flocking machine for automating the manual flocking operation has been proposed. I have.

[Problems to be solved by the invention]

However, each of these wig flocking machines can perform only one type of flocking, V-planting, single-planting, and pan-single planting, with a single device. In order to complete one wig, It is necessary to prepare a plurality of types of wig flocking machines, and to set the wig base to another wig flocking machine during the flocking operation every time the flocking method is changed according to the wig portion. In addition, there is a problem in terms of operability, in particular, because the wig base is fixed and held, and an arbitrary position on the surface is brought to a predetermined flocking position, preferably in a predetermined direction to give a desired hair flow. Head unit was needed.

In view of the above, the present invention can be carried out by a single hair transplanter while appropriately mixing various hair transplanting methods, for example, V planting, single planting, bread single planting, and the like. A wig flocking machine that can be attached to the wig base and can bring an arbitrary position on the surface of the wig base to a predetermined flocking position without the already planted hair interfering with the next flocking operation. The purpose of the present invention is to provide a head unit.

[Means and actions for solving the problems]

According to the present invention, the above object is to provide a head unit having a head portion for fixing and holding a wig base, a hair supply unit for supplying hair to a position where hair is to be fixedly fixed on the head portion, and a hair feeding unit. A wig hair transplanter comprising: a hair transplant unit having a hair transplant needle that transplants the hair supplied by the hair supply unit to a predetermined position of a wig base; and a controller that controls each of these units by a preprogrammed procedure. The head portion of the head unit is pivotally driven about a horizontal axis passing through the center of the head portion, and is pivotally driven about the central axis of the head portion while being pivoted about the horizontal axis, and at least the entire unit or at least The head portion is translationally driven in the vertical direction, and preferably the entire unit is also pivotally driven around a vertical axis, and further, When the head unit is translated in the vertical direction, the positioning means provided on the body of the hair transplanter brings the surface position of the wig base fixedly held by the head unit on the vertical axis to the hair transplant position where the hair transplant operation is performed. It is achieved by making it come.

According to this invention, prior to the flocking operation, the head portion is first rotated about the horizontal axis, and in this state, it is rotated about the central axis of the head portion, and further by the height positioning means,
By automatically adjusting the surface position of the wig base to the height at which flocking is performed and translating in the vertical direction, any position of the wig base fixedly held on the head is automatically adjusted to the height at which flocking is performed. Can be brought to
The flocking position is automatically set for the next flocking operation.

It is configured to be. Further, the flocking needle 42 is configured to perform a predetermined flocking operation by being rotationally driven by the motor 47 in the axial direction, that is, around the straight line P.

The flocking needle 42 does not necessarily have to be provided on a straight line inclined with respect to the flocking position B of the head portion 22, and may be arranged, for example, along a horizontal axis. Furthermore, the direction in which the flocking needle 42 is driven to translate is not limited to the triaxial direction. For example, the hair implantation operation may be performed by moving the head portion 22 up and down by the motor 25 without moving the hair implantation needle 42 up and down in the R direction. But,
In the case of such a configuration, when the flocking needle 42 performs the flocking operation, the other head unit 21 or the bristle feeding unit 31
Will be adjusted accordingly.

The hair transplanter equipped with the head unit according to the present invention is configured as described above. According to the above-described embodiment, the hair transplanter further includes the hair removing unit 51.

As shown in an enlarged view in FIG. 3, the hair removing unit 51 includes a substantially wedge-shaped guide body 52, a cylindrically formed tip 52a having a lower side under the flocking unit 41, and a flocking needle 42 having a flocking needle 42. The swing arm has a roller 54 that is supported so as to extend to a position beyond the flocking position B where the operation is performed, and further has a roller 54 that is rotationally driven by a motor 53 behind the guide body 52.

Can be pivoted around a horizontal axis 55a by a cylinder 56 so that the tip 52a of the
Can be moved along.

A belt-shaped brush 59 is wound around the guide body 52 and the roller 54 as shown in the figure, and the roller 54 is rotated by the motor 53, whereby the tip 52a of the guide body 52 is indicated by an arrow. So as to move from top to bottom. At this time, in order to restrict the displacement of the brush 59 to the side, the swing arm 55 is provided with side guides 55b on both sides at the end thereof.

Preferably, in order to eliminate the slack of the brush 59, the guide body 52 is supported so as to be slightly slidable in the longitudinal direction with respect to the swing arm 55, and is pressed in the direction of its tip by the spring 52b. As a result, the brush 59 can always be stretched. In addition, if the tip of the guide body 52 is formed to be flexible along the convex curved surface of the head portion 22, the planted hair can be effectively aligned.

Thus, the hair removing unit 51 moves the tip of the guide body 52 by the operation of the cylinder 57 before the flocking operation of the flocking unit 41.
52a is brought to the position below the flocking position B where the flocking needle 42 performs the flocking operation on the lower side of the flocking unit 41, and then the tip 52a of the guide body 52 is swung downward by the operation of the cylinder 56 to move the head. The surface of a wig base (not shown) attached to the head portion 22 of the unit 21 is brought into contact with the surface of the wig base. The hair that has already been transplanted to the wig base at is pulled out to the front, and after brushing, the guide body 52 is retracted. Note that the hair brushing unit 51 may be configured by a comb-shaped brush instead of the belt-shaped brush, or may be configured by blowing air with a blower or the like.

A hair transplant operation of a system is performed. By controlling the motors 23, 24, 25, and 26 of the head unit 21, the head portion 22 of the head unit 21 The wig base attached to the head section 22 of the head unit 21 is already planted near the flocking position by controlling the motor 53 and the cylinders 56 and 57 of the hair brushing unit 51. Pull out the set hair and align it.

The wig hair-implanting machine equipped with the head unit according to the present invention is configured as described above, and the hair-implanting operation thereof is performed as follows.

First, before starting the hair transplanting operation, the hair transplantation data of the wig corresponding to the user's depilation state or various hairstyles, that is, the flocking position relating to the wig base to be transplanted and the flocking method at the flocking position (V planting, single planting, pan single planting) , Etc.), and data on the direction of hair flow are input to the control device in advance. Then, a wig base (not shown) to be implanted is set on the head section 22 of the head unit 21, and the hair H is set on the hair supply unit 31 from a hair supply section (not shown) as shown in the drawing.

From this state, the flocking operation of the present wig flocking machine 10 is started.

First, the motors 23, 24, 25 and 26 of the head unit 21 are operated based on the data of the flocking position, respectively.
The head section 22 is rotated by a motor 23 around the X axis.
Is driven around the central axis A'and in the Z-axis direction by the motor 25 on the basis of the signal from the position sensor unit 27, and the height of the arbitrary position to be planted is automatically adjusted on the Z-axis. Is brought to the bristle implanting position B, and the whole is rotationally driven around the Z axis by the motor 26 to be set in an arbitrary direction. As a result, the head section of the head unit 21
The wig base attached to 22 is brought in a desired direction at the desired bristle implantation position B on the Z axis at the bristle implantation position B.

Subsequently, when the cylinder 38 of the hair supply unit 31 is operated, the hair H in which the hair supply rod 33 is stretched between the clamp portions 32a and 32b is implanted into the head portion 22 by the fork-shaped point. Bring it near position B.

Simultaneously, by operating the motors 43 and 44 of the flocking unit 41, the flocking needle 42 is brought to the flocking position B, penetrates the wig base, and the needle tip is exposed to the surface. And
When the hair H stretched on the hair supply rod 33 is hooked on the hair implantation needle 42, the hair supply rod 33 is returned to the position shown in FIG.

Here, the motors 44, 45, 46, 47 of the flocking unit 41 and the cylinder 39 of the bristle feeding unit 31 are each operated according to a procedure programmed in advance based on the data of the flocking method, so that the flocking needle 42 is It is driven in translation in the P, Q, and R directions, and is pivotally driven about its axis P, and thus, at a predetermined flocking position of the wig base set on the head portion 22 of the head unit 21, a predetermined flocking method, that is, V The planting is performed in a predetermined planting direction by planting, single planting, bread single planting, or insertion planting.

After flocking, the cutting means 300 (see FIG. 2 (B))
The hair H that has been transplanted to a predetermined position on the wig base is cut near the clamp portion 32a of the hair gripping portion of the hair feeding unit 31, and the motor 34 of the hair feeding unit 31 is actuated so that the hair gripping portion 32 is indicated by an arrow. The clamp portion 32a is driven to rotate in the direction C, and the clamp portion 32a moves to the position of the clamp portion 32b shown in the drawing, and the clamp portion 32b moves to the position of the clamp portion 32a shown in the drawing. At this time, the clamp portion 32a firmly grips the hair H. The hair H is pulled along with the swiveling motion, and the hair H is thus stretched between the clamp portions 32a and 32b.

Finally, the cylinders 56 and 57 of the hair removing unit 51 are respectively actuated, so that the tip end of the brush 59 of the hair removing unit 51 causes the hair to be transplanted next to the wig base attached to the head portion 22 of the head unit 21. The brush 59 is brought to a position beyond its proper position and brought into contact with the surface of the wig base, and the rotation of the motor 53 drives the brush 59 to circulate in the direction of the arrow (see FIG. 3 (B)) to tip the brush 59. The hair that has already been planted underneath is pulled out toward you.

In this manner, one flocking operation is completed, and the above operation is performed again based on the next flocking data. Thus, the head portion of the head unit 21 is repeated by repeating the flocking operation.
Wig base flocking set at 22 is completed.

It should be noted that the components such as the hair transplanting, the hair feeding and the hair brushing units are not limited to those described above, and it is obvious that various components can be applied.

〔The invention's effect〕

As described above, according to the present invention, the substantially hemispherical head portion of the head unit for fixing and holding the wig base is
The head is pivotally driven around a horizontal axis passing through the center of the head portion and further pivotally driven around the central axis of the head portion while being pivoted around the horizontal axis. The height positioning means is configured such that the surface position on the vertical axis of the wig base fixedly held by the head portion is translationally driven in the vertical direction to the position where the hair transplanting operation is performed.

Therefore, if the flocking data, that is, the flocking position and the flocking method are input to the control device in advance, the head portion of the head unit is set to a predetermined flocking position and automatically brought to the height at which the flocking is performed. Based on the input flocking position and the data of the flocking method, the next step of flocking operation is performed at the predetermined positions of the wig in sequence, V planting, single planting, pan single planting or inserting planting. It will be automatically performed by a predetermined flocking method such as.

Furthermore, if the entire head unit is driven to rotate around the vertical axis, the wig base can be directed in a predetermined flocking direction, so that the flocking can be performed with a desired programmed hair flow. It becomes possible.
