Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flocking unit for performing a flocking operation on a wig base in a wig flocking machine for automatically transplanting hair to 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, and in particular, it is practically impossible to perform a three-dimensional flocking operation of a flocking needle according to various flocking methods by a single machine.

In view of the above points, the present invention makes it possible to perform hair transplantation with a single hair transplanter while appropriately mixing various hair transplantation methods, such as V planting, single planting, and bread single planting, and to obtain a desired hair flow. Wig flocking that can be attached to the wig base and can hold any wig base fixedly and bring any position on the surface to a predetermined flocking position without disturbing hair that has already been planted. The purpose is to provide a flocking unit in a machine.

[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 for transplanting the hair supplied by the hair supply unit to a predetermined position of a wig base; and a controller for controlling each of these units by a preprogrammed procedure. The flocking needles of the flocking unit are arranged on a straight line that is inclined with respect to the flocking position of the head portion that is brought in during flocking, and the flocking needles are pivotally driven around the straight line and this straight line is It is configured so as to be translationally driven in three axial directions about the axis, and the translational drive in the linear direction is performed by a plurality of, preferably two, drive mechanisms. It is achieved by.

According to the present invention, the hair-implanting needles are arranged on a straight line inclined with respect to the hair-implanting position of the wig base, and the hair-implanting needles can be translationally driven in a three-dimensional direction while rotating, so that various hair-implanting methods can be performed. Regardless of the above, the hair transplant needle can move in any direction according to a preset operation sequence, and hair is automatically transplanted by hooking the hair supplied from the hair supply unit.

Furthermore, by using a plurality of drive mechanisms for allowing the flocking needle to move forward and backward, it is possible to start and end the flocking operation and speed up the flocking operation.

〔Example〕

Hereinafter, the present invention will be described in detail based on one embodiment shown in the drawings.

FIG. 1 shows an embodiment of a wig flocking machine provided with a flocking unit according to the present invention. This wig flocking machine 10
Are the head unit 21, the hair supply unit 31, the hair transplant unit 41
And a hair brushing unit 51, each of which is preferably fixedly arranged on a movable frame 11.

Note that each of these units does not necessarily need to be disposed on the frame 11 as a single unit as long as it has a configuration and a function to be described later.Each unit includes, for example, a hair feeding portion and a hair transplant portion. It is also possible to constitute them by being integrated as one unit, and these arrangements can be arbitrarily changed variously without departing from the spirit of the present invention.

 First, the head unit 21 will be described.

The head unit 21 has a substantially hemispherical head portion 22 for fixing and holding a wig base (not shown) to be planted.
A wig base made of, for example, a soft synthetic resin separately made of polyurethane, silicone, or the like or made of a net having a fine mesh is fixed on the head portion 22 by an appropriate method such as tacking or sticking. Is done. The head section 22 is pivotally driven by a motor 24 about a center axis A 'perpendicular to the head section 22 with respect to the center A of the substantially hemispherical shape, and together with the rotation drive mechanism about the center axis A', the head section 22 is rotated. The motor 23 is driven to rotate around a horizontal axis (this is defined as an X axis).

Further, in the illustrated embodiment, the head unit 22 including the above-mentioned turning drive mechanism is driven by the motor 25 in the vertical direction (that is, the Z-axis direction).
, And the entire head unit 21 is turned around the Z axis by the motor 26.

Thus, the head section 22 of the head unit 21 is
By the operation of 23, 24 and 25, any position on the surface
It is brought to the shaft implantation position B on the shaft and can be set in a desired direction by the operation of the motor 26.

Here, in the above embodiment, the head unit 21 includes:
The head 22 including the rotation drive mechanism of the motors 23 and 24 is
Although it is configured to be driven in translation in the vertical direction at 5, even if the entire head unit 21 is driven to translate as in the wig flocking machine disclosed by the present applicant in Japanese Patent Application No. 62-106590. Good. Further, in the above embodiment, the entire head unit 21 is configured to be swiveled around the Z axis, thereby enabling the setting of the flocking direction, that is, the setting of the hair flow. When it is not necessary to automatically adjust the head unit 21, the motor 26 for rotating the head unit 21 as a whole is unnecessary.

Above the head portion 22, an optical position sensor portion 27 is fixedly arranged on the frame 11 as a positioning means for detecting the height of the wig base at the flocking position and adjusting the height. . As a result, the surface of the wig base at the position on the Z-axis of the wig base is adjusted by the motor 25 before the flocking operation based on the detection signal from the position sensor unit 27, and the flocking position B is accurately determined.
Can be brought to

Here, the position sensor unit 27 is disposed on the frame 11 above the head unit 22.
The set position is arbitrary as long as the surface at the position on the axis can be adjusted in height. Further, the position sensor unit 27 is not limited to the optical detector shown in the figure, and various means may be selected. For example, the position sensor unit 27 may be constituted by a limit switch, a stopper provided at a predetermined position of the flocking machine 10, or the like.

The head portion 22 is formed of, for example, an epoxy resin or a rubber material so that a flocked needle described later is not broken, and the substantially hemispherical surface has a concave curved portion of a wig base manufactured according to a user's head shape. It is preferably shaped to have a convex curved surface that conforms to the inner surface and is removably supported and secured on a base.

As shown in the enlarged view of FIG. 2, the hair supply unit 31 has a main body fixedly arranged obliquely with respect to the frame 11 and hair supplied from a hair supply unit (not shown). A hair gripping portion 32 provided with two clamp portions 32a and 32b for gripping H on the opposite side in the diameter direction, and the hair H gripped by the two clamp portions 32a and 32b are placed near the flocking position B of the head portion 22. It has two parallel hair feeding rods 33 each having a fork-shaped tip to be brought (see FIG. 2 (C)).

The hair gripper 32 is a motor with a clutch brake.
34, the hair is intermittently driven in the direction of arrow C by 180 degrees every one flocking operation, so that the two clamp portions 32a, 32a,
32b is stopped by, for example, a click mechanism or the like so as to be located side by side so as to face the head portion 22.

Each of the clamp portions 32a and 32b has two frustoconical disks 3
5a and 35b are vertically opposed and the lower disk 35a is fixed to the hair gripper 32, and the upper disk 35b is along the center axis of the lower disk 35a with respect to the lower disk 35a. It is slidably held up and down, and a lower disk 35a is held by a spring 36.
Is abutted against A rod 35 extending downward from the center of the upper disk 35b in the central axis direction.
The lower end of c is always in contact with the annular cam surface 37 formed on the upper surface of the main body of the hair supply unit 31 in accordance with the rotation of the hair gripper 32, so that the clamps 32a and 32b The hair H is firmly gripped at a position in front (that is, the position of the clamp portion 32b), and the other one of the clamp portions 32 is held.
In the position a, the hair H is loosely gripped so that the supplied hair H is kept in tension, and the hair H is opened to grip the hair H in a position rearward with respect to the head portion 22. It has become.

The hair supply rod 33 is moved in the thrust direction by the operation of the cylinder 38, and the two fork-shaped tips of the hair supply rod 33 respectively hook the hair H while the head portion of the head unit 21 is moved.
22 and reaches the position sandwiching the flocking position B,
Abuts the surface of the wig base attached to 22. Further, one or both of the hair supply rods 33 are telescopically constructed so as to be telescopic as shown in FIG. 2D, for example, and are held in an extended state by a spring or the like. Accordingly, when the two hair supply rods 33 come into contact with the wig base near the flocking position B, they can surely come into contact with the wig base. In FIG. 2 (B), reference numeral 300 denotes a cutting means comprising a burning iron or a cutter for cutting the hair H after the hair implantation.

Thus, the hair supply rod 33 supplies the hair H gripped by the clamps 32a, 32b of the hair gripper 32 by the operation of the cylinder 38 to the vicinity of the flocking position B of the head 22 of the head unit 21, which will be described later. So that the flocking unit 41 V
In conjunction with the flocking operation such as planting, bread single planting, single planting, etc., the hair H is transplanted to the flocking position B by operating the cylinder 39.
And constitute a part of the flocking operation.

Next, a preferred example of the flocking unit 41 according to the present invention will be described.

The main body of the flocking unit 41 is fixedly arranged with respect to the frame 11, and the head portion 22 of the head unit 21 is
The flocked needle 42 is provided on a straight line P inclined with respect to the flocked position B. The flocking needle 42 is configured to be translationally driven in each of the three axes P, Q and R with the straight line P as one axis.

That is, the flocking needle 42 is brought from the retracted position to the vicinity of the flocking position by being largely translated by the motor 43 in the direction of the straight line P along the guide 43b via the crank 43a, and the flocking needle 42 is also moved. In order to align the hair with an appropriate flocking position, the motor 44 moves the motor 45 in the direction of the straight line P.
In the direction of the horizontal axis Q perpendicular to the straight line P, and
46, the R direction perpendicular to the P direction and the Q direction,
Are driven in translation in three axial directions. 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.

Here, in the above example, the operation of the flocking needle 42 in the direction of the straight line P, that is, in the front-back direction is configured to advance and retreat by the two motors 43 and 44 as the first and second drive mechanisms. As a result, it is possible to increase the forward / backward movement speed by driving the motor 44 at the same time while the flocking needle 42 is largely forward / backward by the motor 43. Therefore, the motor 44 complements the motor 43 in order to increase the forward / backward movement speed of the flocking needle 42, and also functions for accurate alignment to the flocking position described above.

The flocking needle 42 does not necessarily have to be provided on a straight line that is inclined with respect to the flocking position B of the head portion 22, and may be arranged, for example, along a horizontal axis. , Will be translationally driven in three axial directions with respect to the central axis of the needle which coincides with the horizontal axis.

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. However, in the case of such a configuration, when the flocking needle 42 performs the flocking operation, the other head unit 21 and the bristle feeding unit 31 are also adjusted.

The wig flocking machine provided with the flocking unit according to the present invention is configured as described above, and according to the above-described embodiment, the flocking machine further includes the hair removing unit 51.

As shown in the enlarged view of FIG. 3, the hair removing unit 51 has a substantially wedge-shaped guide main body 52, a cylindrical tip 52a of which is on the lower side of the hair transplanting unit 41, and a hair transplanting needle 42 of which the hair is transplanted. It is supported so as to extend to a position beyond the flocking position B at which the operation is performed, and further behind the guide body 52,
A swing arm 55 having a roller 54 driven to rotate by a motor 53 is provided. This swing arm 55 is a guide body.
The cylinder 52 can be rotated around a horizontal shaft 55a by a cylinder 56 so that the tip 52a of the 52 can be vertically swung, and the whole body is horizontally guided by a cylinder 57 in the longitudinal direction of the guide body 52.
It can be moved along 58.

A belt-shaped brush 59 is wound around the guide body 52 and the roller 54 as shown in the figure. When the roller 54 rotates through the motor 53, the end of the guide body 52
It may be circularly driven to move from top to bottom as indicated by the arrow at 52a. 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 below the flocking unit 41 to a position beyond the flocking position B where the flocking needle 42 performs the flocking operation, and then the cylinder 52 is actuated to swing the tip 52a of the guide body 52 downward 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 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.

The head unit 21, the hair feeding unit 31, the hair transplanting unit 41, and the hair brushing unit 51 described above are connected to a control device (not shown), and the control device operates the motor 34, Cylinder 38,
By controlling the motors 39 to 43 and the motors 43 to 47 of the flocking unit 41, for example, any one of V planting, single planting, pan single planting, and insertion planting based on the data of the flocking system input in advance to the controller. 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 in the Z-axis direction by the motor 25 on the basis of a signal from the position sensor 27, and the arbitrary position to be implanted is height-adjusted on the Z-axis so that the implantation position is B and the entire motor 26
Is driven to rotate around the Z axis and set in an arbitrary direction. As a result, the wig base attached to the head portion 22 of the head unit 21 is brought in the desired direction at the flocking position B on the Z-axis at the desired position for flocking.

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 implanted at 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 further, the motor 34 of the hair feeding unit 31 is operated, and the hair gripping portion 32 is pointed by an arrow. The clamp portion 32a is moved to the position of the illustrated clamp portion 32b, and the clamp portion 32b is moved to the position of the illustrated clamp portion 32a. At this time, the clamp portion 32a firmly grips the hair H. The hair H is pulled along with the turning motion, whereby the hair H is stretched between the clamp portions 32b and 32a.

Lastly, by operating the cylinders 56 and 57 of the hair brushing unit 51, the tip of the brush 59 of the hair brushing unit 51 is implanted next to the wig base attached to the head section 22 of the head unit 21. The brush 59 is brought to a position beyond the expected position and is 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)). The already planted hair under the head is pulled out.

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 head unit is not limited to the above-described parts such as the hair supply and hair removal units, and it is obvious that various types can be applied.

〔The invention's effect〕

As described above, according to the present invention, the flocking needle of the flocking unit is arranged on a straight line that is inclined with respect to the flocking position of the wig base that is fixedly held by the head portion that is brought in during flocking. Is driven around the above straight line and is translationally driven in three axial directions with the straight line as one axis, and the translational drive in the straight line direction is performed by a plurality of, preferably two, drive mechanisms. Therefore, the hair transplanting needle hooks the hair supplied from the hair supplying unit, so that the hair transplanting operation is sequentially performed at the predetermined positions of the wig base based on the predetermined input hair transplanting position and the data of the hair transplanting method. It will be automatically carried out by a predetermined flocking method such as planting, bread single planting or insertion planting.

Further, by providing a plurality of drive mechanisms, for example, two drive mechanisms for allowing the flocked needle to move forward and backward, it is possible to further improve the operation speed of the flocking operation and the operation speeds of its start and end.

For example, a configuration may be adopted in which the flocking needle is largely translated by the first drive mechanism between the retracted position and the flocking position, and the flocking needle is simultaneously translated by the second drive mechanism during the driving. For example, the flocking needle can move back and forth at a higher speed.
