FIG. 1 is a side view of the automatic hair transplanting device, and FIG. 2 is a front view of the automatic hair transplanting device. As shown in FIGS. 1 and 2, the automatic flocking device 120 includes an eccentric 10, a flocking hook 20, a pull-out hook 30, a stocker 40, a thread positioning bar 50, a thread dropping bar 60, a thread pulling bar 70, a reversing roller 80, It includes a magnet, a drive mechanism, a control device, etc. (not shown). In the side views and front views shown in FIGS. 1 to 4, the left-right direction in the figures is the horizontal direction, and the up-down direction is the vertical direction.

The hair material 100a is artificial hair (fiber, synthetic fiber), human hair (hair collected from humans), animal hair (hair collected from animals other than humans), or a mixture thereof. Any hair or hair-like material that can be implanted by device 120 is included. Further, the flocked net 200 has a mesh shape including, for example, a plurality of warp threads 201 and a plurality of weft threads 202.

As shown in FIGS. 1 and 2, a hair material bundle 100b consisting of a plurality of hair materials 100a that have been trimmed in advance is placed in the stocker 40. Hereinafter, in the horizontal plane, the direction in which the pull-out hook 30 is located when viewed from the eccentric 10 will be referred to as the rear, and the opposite direction will be referred to as the front, and these will be collectively referred to as the front-rear direction. In addition, the direction perpendicular to the front-rear direction in a horizontal plane is called the depth direction, and when looking from the front to the rear, the left side is the back side (back side of the paper in Figure 1), and the right side is the front side (Figure 1 (front side of the paper).

The flocked net 200 is set so as to cover the net hanging part 11 of the eccentric 10 from above, and also contacts the reversing roller 80 to regulate its position. The stocker 40 has a bottom portion 41 and a pair of opposing side plates 43, and the hair material bundle 100b is placed on the bottom portion 41. Note that, as shown in FIG. 2, only one stocker 40 may be provided, or a plurality of stockers 40 may be provided. Further, the hair materials 100a placed in the stocker 40 may be a mixture of hair materials having different types, such as color, thickness, hardness (elasticity), etc.

The flocking hook 20 includes a hook 21 at the tip and a latch 22 that opens and closes the needle opening of the hook 21. The flocking hook 20 is driven by a drive mechanism controlled by a control device, and ties the hair material 100a to the flocking net 200 for flocking. The pull-out hook 30 is a member that captures the hair material 100a from the stocker 40, and is provided with a hook 31 at its tip that can capture one (or more than one) hair material 100a.

The thread positioning bar 50 is a member that guides the hair material 100a drawn out from the stocker 40 by the drawing hook 30 to a predetermined position. The thread dropping bar 60 is a drive mechanism controlled by a control device that vibrates in the vertical direction, and brushes off the hair material 100a drawn in by the thread pulling bar 70. The thread pulling bar 70 is moved in the front-rear direction by a drive mechanism controlled by a control device, and hooks the flocked hair material 100a on the flocked net 200 and draws it forward.

Next, the operation of the automatic hair transplantation device will be explained. The automatic hair transplanting device operates as follows, with the state shown in FIG. 1 as the initial state. (1) The yarn pull-in bar 70 advances rearward to a position beyond the outlet 42 of the stocker 40. (2) The withdrawal hook 30 ascends until the tip including the hook 31 enters the stocker 40 from the extraction port 42, captures the hair material 100a, and descends. (3) The flocking hook 20 advances toward the rear, and the hook 21 passes under the weft thread 202-1. (4) The shaft portion 13 is rotated 90 degrees so that the relief portion 12 of the eccentric 10 faces upward. (5) As shown in FIG. 3, the hair transplant hook 20 advances toward the rear. (6) The hair flocking hook 20 is rotated so that the needle opening of the hook 21 is facing upward to the state facing the hair material 100a (facing the back side), and the hair material 100a is inserted with the needle opening. Capture. (7) After the flocking hook 20 rotates so that the needle opening of the hook 21 faces upward, it advances forward and passes below the weft thread 202-1. At this time, the latch 22 comes into contact with the weft thread 202-1 and the needle opening is closed, but then the latch 22 is attracted by a magnet (not shown) and the needle opening is opened. (8) The hair transplanting hook 20 moves backward, rises, rotates, and twists the hair material 100a to form a loop. (9) As shown in FIG. 4, the flocking hook 20 advances toward the rear. (10) The hair transplanting hook 20 is rotated so that the needle opening of the hook 21 is directed upward to the hair material 100a (facing the back side), and the hair material 100a is inserted with the needle opening. Capture. (11) After the hair transplanting hook 20 rotates so that the needle opening of the hook 21 faces upward, it advances forward and passes through the loop of the hair material 100a. At this time, the latch 22 contacts the loop of the hair material 100a and the needle opening is closed. (12) The thread pulling bar 70 moves forward to pull the hair material 100a forward and returns to the initial state. The eccentric 10 and the flocked hook 20 return to their initial states. At this time, the latch 22 is attracted by a magnet (not shown) and the needle opening is opened. The thread drop bar 60 moves downward to style the hair material 100a downward, and then moves upward to return to the initial state.

In the above operation (2), after the tip of the withdrawal hook 30 is inserted into the extraction port 42, it moves slightly to the front side (the side where the needle opening 32 of the hook 31 is opened), and the hair is removed from the hook 31. The hair material 100a may be easily captured. In the operations (6) and (10) above, in order to make it easier to introduce the hair material 100a into the needle opening of the hook 21, the pull-out hook 30 may be moved to the front side, or the pull-out hook 30 and the flocked hook 20 may be moved to the front side. may move toward each other. Further, in FIGS. 3 and 4, the flocking hook 20 is shown to capture the front part of the hair material 100a folded in half by the operation (6) above, and capture the rear part by the operation (10) above. However, in each movement, either the front or the rear may be captured. In the operation (7) above, the flocking hook 20 does not need to rise. Further, in this operation, the flocking hook may rotate one or more rotations, or may rotate half a rotation. In the operation (11) above, when the flocking hook 20 passes through the loop of the hair material 100a, the pulling hook 30 may move up and down little by little. Thereby, the hook 31 comes off from the hair material 100a, and peeling in which the hair material 100a curls due to friction is prevented.

<<Configuration of hair material bundle and stocker>>
The configurations of the hair material bundle 100b and the stocker 40 will be described below.
