[0002]

2. Description of the Related Art As a protruding state detecting device for a rod-shaped body, there is one disclosed in JP-A-53-49265. In this conventional technique, the wiring terminals on the back surface of the printed circuit board are irradiated with a laser beam, and the presence or absence of an abnormal protruding state of the wiring terminals is detected by a change in the amount of transmitted light.

[0003]

However, in the prior art, when the adjacent wiring terminals are both abnormally protruding, the adjacent wiring terminals are arranged so as to form a line on the optical axis of the laser beam. If there is one, the amount of transmitted light of the laser beam is indistinguishable from the case where there is only one abnormal protruding terminal that is not adjacent to other terminals, and two or more abnormal protruding terminals are adjacent. Cannot be detected.

Therefore, for example, even if the conventional technique is used for extracting the operating condition for trimming the protruding portion of the bristle protruding from the standard bristle implantation level by the irradiation of the laser beam in the hair straightening device of the brush, the standard It is indistinguishable whether or not there are two or more adjacent hairs protruding from the flocking level. This means that two or more adjacent hairs are irradiated with the laser beam in order to align the protruding hairs with the standard flocking level, and as a result, the protruding hairs of the two or more hairs are cut. This means that there is a possibility that the subsequent fused portions may be fused to each other to produce a defective brush.

An object of the present invention is to make it possible, when detecting the presence or absence of a rod-shaped body protruding from a rod-shaped body group, to determine whether or not two or more rod-shaped bodies are adjacently projected.

[0006]

According to a first aspect of the present invention, there is provided a rod-shaped protruding state detecting device for detecting a rod-shaped body protruding from a rod-shaped body group, wherein the rod-shaped body protruding state detection device faces each other with a detection region interposed therebetween. Use two or more sets of photodetectors that can detect the light blocking state of a rod-shaped body, and arrange the photodetectors of each set so that the detection optical axes of the photodetectors of each set are not parallel to each other. Then, a discriminating means for discriminating the protruding state of the rod-shaped body is provided based on the detection results of the photodetectors of each set.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the light-shielding state by the rod-shaped body is detected under the state where the photodetectors of each set move relative to the rod-shaped body. It was made possible.

According to a third aspect of the present invention, in addition to the first or second aspect of the present invention, the operating condition of the rod-shaped body trimming device that the determination result of the determination means aligns the rod-shaped body group to a substantially constant standard level. It is intended to be used as.

[0009]

According to the present invention, there are the following actions.

Since the detection optical axes of two or more photodetectors are not parallel to each other, they are arranged in a line so as to overlap each other, and the protruding state of two or more adjacent rod-shaped bodies is set to the light of each set. It can be determined based on the detection result (detection pattern) of the detector.

By configuring the photodetectors of each set to move relative to the rod-shaped body, the protruding state of the rod-shaped body can be continuously detected.

By using the determination result of the determination means as the operating condition of the rod-shaped trimming device, only the protruding portions of the rod-shaped bodies which are not adjacent to each other are trimmed, and the protruding portions of two or more adjacent rod-shaped bodies need not be trimmed. Can be processed as

The set of laser beam detectors 31 and 32 is fixed.
The movable inspection table 34 includes a drive motor 35, and the operation of the drive motor 35 causes each set of the laser beam detectors 31 and 32 to be held by the toothbrush holding jig 22. In contrast to this, the light blocking state by the bristles 11 can be detected under the state of relative movement. In FIG. 1, S is a moving stroke of the movable inspection table 34.

The discrimination result of the discriminator 33 indicates that the hair 1

However, at the timing when the hair straightening position 20D is reached, it is automatically controlled to execute the hair straightening operation by scanning the laser beam 13.

Therefore, the discriminator 33 of the top protrusion detector 25
The discriminating operation is performed as follows (see FIGS. 6 and 7). First, the basic detection pattern of the top surface projection detector 25 is as shown in FIGS. In FIG. 7, L
Indicates a threshold value for detecting a light shielding state by one or more protruding portions of the hair 11 and H indicates a threshold value for detecting a light shielding state by two or more protruding portions of the hair 11. And, in (A), two adjacent hairs 11A and 11B are laser beam detectors 3.

And the laser beam detector 32 detects the amount of light shielding exceeding L and H, (E) is adjacent 2
When the hairs 11A and 11B of the book are parallel to the detection optical axis of the laser beam detector 31, and the two hairs 11A and 11C that are not adjacent to each other are parallel to the detection optical axis of the laser beam detector 32 In addition, the laser beam detector 31 detects only the light shielding amount exceeding L, and the laser beam detector 32

There are two or more protruding hairs 11, and it is determined that the trimming cannot be corrected. (2) The output of the laser beam detector 31 exceeds L or the output of the laser beam detector 32 is L. When it exceeds, it is determined that there is a hair 11 that protrudes independently, but does not protrude adjacent to the other, and that the trimming correction is necessary. (3) The laser beam detectors 31 and 32 When both outputs do not exceed L, there is no protruding hair 11,
It is determined as a good product. The discriminator 33 uses the above (1) to
After the determination of (3), the movable inspection table 34 is stopped, and the determination result is transferred to the laser device 27 as described above and used as the trimming operating condition.

It is possible to easily determine that the adjacent two or more bristle hairs 11 are both in a protruding state exceeding the standard hair transplantation level, and it can be determined that the trimming cannot be corrected. In addition, even though the pattern of FIG. 7D is a product that requires trimming correction, three sets of laser beam detectors are used as the top protrusion detector 25 in order to prevent the defective product from being determined.

As a result, compared to the case where two sets of laser beam detectors 31 and 32 are used,
More accurate discrimination is possible.

Next, the operation of the above embodiment will be described.

Two or more sets of laser beam detectors 31,
Since the detection optical axes of 32 and 36 are not parallel to each other, they are arranged in a line so as to overlap each other, and the protruding state of two or more adjacent hairs 11 is determined by the laser beam detector 3 of each set.
It can be determined based on the detection results (detection patterns) of 1, 32, and 36.

Each set of laser beam detectors 31, 3
By configuring 2 and 36 to move relative to the bristle 11, the protruding state of the bristle 11 can be continuously detected.

By using the discrimination result of the discriminator 33 as the operating condition of the laser device 27 in the hair straightening device 20, only the protruding portion of the hair 11 which is not adjacent to the other is trimmed, and two or more adjacent hairs 11 are trimmed. It is possible to process the protruding portions of No need to trim.

That is, in the hair styling device 20, the trimming correction is necessary only when there is one independently protruding hair 11, and two or more adjacent hairs 11 protruding adjacently are determined. In some cases, it is determined as a defective product that cannot be trimmed and corrected. Therefore, a defective brush is manufactured in which the protruding portions of two or more adjacent bristles 11 are cut and their fused portions are fused to each other. Therefore, the end portions of all the bristles 11 can be aligned at the standard bristle implant level and can be maintained in a bulging state.

In the practice of the present invention, the photodetector does not necessarily have to be a laser beam detector.
