Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for hooking the hook once it is pulled up onto the base and formed, or in the case of a double knotting method, the hair ring is pulled up onto the base a second time and formed and then penetrated again or again. This invention relates to a device for preventing damage to the hair ring and the base when the hook of a hair flocking sewing machine is raised and lowered again, which is characterized by holding the existing hair ring flat against the base surface when the hair ring is raised and lowered.

The present inventor completed the invention of a method and device for mechanically transplanting hair suitable for wigs, etc. using a sewing machine equipped with a two-stage hook needle, and the invention was published in Japanese Patent Application No. 50-53751. Patent No. 1055208) and Japanese Patent Application No. 52-45523 (Patent No. 1045522). When the hook moves up and down, the natural state of the hair ring is that it is pulled upward and shaped, and then left as it is when the hook changes downward, and the hair ring moves diagonally upward. Since the hook is floating in an elongated, approximately elliptical shape, when the hook needle passes through the hair ring and ascends and descends again, the hook may come into contact with the hair ring on the way, or may catch the base as it rises. This may damage or break the hair, which poses a serious hindrance to the hair transplant operation.
However, the present invention eliminates this hindrance and prevents such damage from occurring, which is highly effective. Now, to explain this in detail with reference to the attached drawings showing an example of its implementation, 1.
passes vertically through the hook rod 3 which serves as a lifting rod and supports the hook needle 2, and a restraining member 4 is attached to the lower end in a state surrounding the outer periphery of the hook needle 2. The restraint 4 is conveniently made of a spring, a rubber or plastic ring, a pipe, or the like. 5 is a control rod, and the proximal end of the control rod is pivoted to the needle rod 3 6
The base end is formed into a forked shape 7 and the upper part of the lifting rod 1 is engaged with it, and the tip comes into contact with and separates from a plate cam 10 having a concave surface which is fixed to a support frame 9 via a cam roll 8. The upper and lower ends of the cam are fixed to a support frame 9 that supports the hook rod 3 in a vertically movable manner. It is a plate cam with different surfaces. Reference numeral 11 denotes a stop fixed to the upper part of the lifting rod 1, and a fork-shaped portion 7 at the base end of the control rod 5 is activated when the plate cam 10 having a concave surface and the cam roll 8 come into contact with each other and separate from each other.
It contacts the upper surface and serves as a contact fulcrum and determines the position and timing of the restraint 4, and the cam roll 8 of the control rod 5 is connected to the plate cam 1 having the concave surface.
When the stopper 11 and the lifting rod 1 are in a position facing the concave surface 10a of 0 and are not in contact with the plate cam 10, they are lowered as shown in FIG. 8A, and the lower end of the lifting rod 1 is restrained. The tool 4 is lowered, the lower surface of the retainer 4 is fixedly positioned on the upper surface of the base 17, the hair ring 18 and the base 17 are pressed and supported under the retainer, and when the hook needle 2 is raised, the base 17 and the hair ring are This has the effect of preventing problems such as 18 being caught and damaged. However, the base 17 in the present invention is a net-like base commonly known as a wig base, and does not have a dense structure like woven fabric, but has gaps through which the hook needle can move up and down.

Next, as shown in FIG. 8B, when the hook rod 3 further rises, the control rod 5 which is pivoted to the hook rod 3 rises at the same time, and the cam roll 8 comes into contact with the protruding surface 10b of the plate cam 10 and rises. Then, the prongs 7 of the control rod 5 push up the catch 11 slightly from below to above, and the lifting rod 1 also rises.
The lower end of the restraint 4 is raised to a position where the large hook 19 of the hook needle 2 is exposed.At this point, the large hook 19 has come out above the hair ring and the base, and the large hook 19 is attached to the large hook 19. This serves to prevent damage to the ring, base 17, etc. Reference numeral 12 denotes a support member which is fixed within the hook rod 3 and passes through the upper part of the lifting rod 1. A stop 13 is provided at the bottom of the lifting bar 1, and a spring 14 is interposed between the stop 13 and the support member 12.

The hair ring and base damage prevention device of the present invention has the above-described configuration. First, as shown in FIGS. As the hook hook rod 3 rises, the hair is lifted onto the base 17 by the hook needle and raised to form the first hair ring 18. As shown in Fig. 3, the hook needle 3 descends again as the sewing machine operates, and the hook needle 3
The lifting rod 1, which is associated with the lifting rod 1, is also lowered together. At this time, the restraint 4 attached to the lower end of the lifting rod 1 is also lowered. In this case, on the upper surface of the base 17, there is a hair ring 18 formed by the first raising of the hook needle 2, which surrounds the hook needle 2 on the base 17, so that when the retainer 4 descends, The hair ring 18, which originally floats vaguely in the shape of an oblique oblong in space, is pressed flatly against the surface of the base 17 with its lower surface, and is forced to float vaguely in the shape of a oblique oblong in space. It is.

Next, when the hook 2 rises, the hook passes through and rises into the bristles 18 which have been pressed into a flat shape, so that even if the bristles 18 etc. are caught, they will not be damaged.
Since the lifting rod 1 is attached to the hook rod 3 via the spring 14, the restraint 4 is resisted by the base 17 and stops descending, and the hook rod 3 descends by itself. Meanwhile, as shown in Figure 3, the first
It is possible to stop on base 17 while compressing 4. Next, as shown in FIG. 3 to FIG.
21, when the lower end of the hook 2 is raised to the base 17 position, the lifting rod 1 is stopped by the extension of the spring 14, and therefore the hair ring 18 is held by the restraint 4. Since it continues to be pressed flat, even though the hook 2 passes through the hair ring 18 and rises as described above, the large hook gets caught on the hair ring 18 and scratches around the base as it passes. There is no risk of damage or breakage, and the purpose of this device is achieved. Once knotted, the hook rod 3 further rises from the state shown in Fig. 4 to connect the hairs 20 and 21 to the base 1.
7 is completed by pulling it upward, but in the case of double knotting, by appropriately changing the groove of the elevating cam, the hook rod 3 undergoes the elevating and lowering process as shown in Figs. 5 to 7. It is something. In this case the fifth
As shown in the figure, the second hair ring 22 created by the hair feet 20 and 21 is attached to the lowered restraint 4 in the same way as described above.
The hook needle 2 further hooks and hooks the bristles 20 and 21 to form a bristly ring 22.
There is no risk that the hook will catch the hair ring 22 or scratch the area around the base, damaging or breaking the hair ring 22 even when the hook passes through the base and rises.

Next, when the lifting rod 1 rises further together with the hook rod 3, the lower end of the hook hook, which is hooked with the second hair, is surrounded by the restraint 4.
There is a risk that even when the bristles are at the rising end, it is difficult to separate from the hook. However, until then, the cam roll 8 of the control rod 5 had been rising without touching the cam 10 in order to face the concave surface 10a of the cam, but as shown in FIG.
The cam roll 8 is attached to the protruding surface portion 10b of the cam due to the curvature of the cam.
The two sides collide, resulting in a downward slope. Therefore, the prongs 7 at the base of the control rod 5 push the catch 11 upward from below, and this pushing-up operation causes the lifting rod 1 to rise slightly apart from the hook rod 3. The restrainer 4 stops surrounding the lower end of the hook needle and changes to an exposed state, so that the exposed bristles 20 and 21 can be easily released from the hook needle by blowing air or the like. It is possible.
