螺子部(2b)を所定方向に揃えるようにしである。As shown in FIG. 3, the stud pole (1) has threaded portions (2a) (2b) at both ends, and a threaded portion (2b) on either one of the threaded portions (2a) (2b).
A sealing agent (3) is applied to the surface of the cylinder block, and the screw portion (2b) of the stud bolt (1) coated with the sealing agent (3) is inserted and fixed into the working hole of the cylinder block. Therefore, the direction of the stud bolt (1) is determined in a step before the work hole closing step, and the threaded portion (2b) coated with the sealant (3) is aligned in a predetermined direction.

た。Incidentally, conventionally, the direction of the stud bolt (1) has been determined by a beam sensor (4) having a light emitting part and a light receiving part arranged side by side on the front surface, as shown in FIG. That is, a stud bolt (1) is installed in front of the beam sensor (4).
) After holding the screw part (2a) or (2b),
When the projection light is projected from the light projection part of the beam sensor (4) onto the threaded part (2a) or (2b), the projected light is transmitted to the threaded part (2a) or (2b).
2a) or the sealant applied to the threaded part (2b) (
After being reflected on the surface of 3), the light is received by the light receiving section. At this time, since the threaded part (2a) of the stud bolt (1) and the sealant (3) have different light reflectances, the beam sensor (4)
The reflected light received by the light receiving part of the stud bolt (1)
There is a difference in strength between the threaded part (2a) and the sealant (3), and the presence or absence of the sealant (3) is detected based on the difference in the strength of this reflected light, and the direction of the stud bolt (1) can be determined. Was.

ができないという問題があった。(Problems to be Solved by the Invention) According to the conventional discrimination method, the presence or absence of the sealant (3) was detected based on the difference in intensity of reflected light received by the light receiving part of the beam sensor (4). Due to dirt, discoloration, etc. on the surface of the sealant (3) of the stud bolt (1), the sealant (3)
) has the same light reflectance as the threaded part (2a),
There is no difference in the strength of the reflected light received by the light receiving part of the beam sensor (4), which causes the problem that the direction of the stud bolt (1) may be misjudged or cannot be determined. Additionally, if the holding position of the stud bolt (1) is slightly misaligned, the direction of reflection of the reflected light reflected by the surfaces of the threaded portion (2a) and the sealant (3) changes, and the reflected light is reflected by the beam sensor (4). ), so there was a problem that the direction of the stud bolt (1) could not be determined.

On the other hand, since the projected light projected onto the threaded portion coated with the sealant passes along the sealant, a difference in appearance occurs in the amount of the projected light passing through the threaded portions at both ends, and this light! The presence or absence of sealant is detected based on the difference.

Projection light (13) is projected toward. Then the projected light (
Since the projection width dimension of 13) is set larger than the diameter dimension of the stud bolt (1), the center part of the projection light (13) is directed to the threaded part (2a) or threaded part (2b) of the stand bolt (1). The projected light (13) is blocked by the applied sealant (3) and protrudes from the stud bolt (1) on both sides (
13a) (13a) is the thread groove (
2a') or along the surface of the sealant (3) applied to the threaded part (2b), the light is received by the light receiver (12), and the projected light (13) passes through the stud bolt (1). The amount of passing light is detected, and the value of the amount of passing light is displayed, for example, digitally, by a discriminator (14) based on this detection signal.

塗布した螺子部(2b)を同一方向に保持する。Then, the passing light amount value of the projected light (13) and the sealant (3
), the amount of passing light is compared with a preset reference value, and the presence or absence of the sealant (3) is detected. Therefore, for example, the threaded portion (2a) of the stud bolt (1)
If a sealant is not applied to the projection light (13), as shown in Fig. 2(a), the passage area of the projection light (13) becomes large, so that the projection light (13) received by the receiver (12) becomes smaller. The amount of transmitted light increases, and it is determined that the threaded portion (2a) of the stud bolt (1) is not coated with sealant, and the threaded portion (2b) of the stud bolt (1) is coated with sealant (3). ), as shown in Figure 2(b), the sealant (3)
Since the area through which the projected light (13) passes is reduced by the applied area, the amount of transmitted light of the projected light (13) received by the receiver (12) becomes smaller, and the sealant (3) is applied. It is determined that there is. In this way, the above sealant (3)
The direction of the stud bolt (1) is determined by the presence or absence of the
If the directions are different, use appropriate means to change the direction of the stud bolt (1) and hold the threaded portion (2b) coated with the sealant (3) in the same direction.

とができる。According to the present invention, the presence or absence of the sealant is detected based on the difference in the amount of transmitted light of the projected light that has passed through the stud bolt. Even if the holding position is slightly misaligned, it is possible to reliably detect the presence or absence of sealant, and as a result, the direction of the stud bolt can be determined accurately and reliably, greatly improving work efficiency. It is possible to make significant improvements.
