することにより行つている。(B) Prior Art When blow molding is performed, air is blown from a blow nozzle into a parison that is built into a blow mold in a temperature-controlled manner. In order to smoothly blow air through the blow nozzle and obtain a good molded product, the center position of the blow nozzle must be aligned with the center position of the mouthpiece of the blow mold. For this reason, the position of the blow nozzle is adjusted before the start of blow molding. Conventionally, the position of the blowing nozzle has been adjusted by lowering the blowing nozzle, bringing it into contact with the mouthpiece of the blowing mold, and visually observing the state of contact.

That is, according to the method for adjusting the position of a blow nozzle in a blow molding machine according to the present invention, a jig having a symmetrical shape with respect to the central axis is placed in the mouthpiece of the blowing mold so that the central axis of the jig is aligned with the central axis of the mouthpiece. The center position of the jig is measured from two intersecting directions using a position detector, and before or after measuring the jig, move the blowing nozzle close to the nozzle without the jig installed. The center position of the blow nozzle is measured from two intersecting directions using the position detector, and the difference between the measurement result of the center position of the jig and the measurement result of the center position of the blow nozzle is set to 0. Adjust the blow nozzle position as follows.

Therefore, by detecting the center position of the jig, the center position of the mouthpiece can be detected. The center position of the blow nozzle is detected by the same position detector, and the position of the blow nozzle is adjusted so that the measurement result of the blow nozzle matches the measurement result of the jig. This will correspond exactly to the center position of the section. Therefore, the position of the blow nozzle can be adjusted accurately without visual inspection by the operator.

じ機構により微調整可能である。 As shown in FIG. 1, a die plate 12 having a conical surface is attached to the center of the upper part of a blowing mold 10 to form a mouthpiece. A position detector 14 is provided on the upper surface of the blowing mold 10 so as to surround the die plate 12. As shown in FIG. 2, the position detector 14 includes two light emitting sections 16a and 16b and a corresponding light receiving section 18a.
and 18b, and the optical axis of the light emitting part 16a and the light receiving part 18a, and the optical axis of the light emitting part 16b and the light receiving part 18
They are arranged so as to be perpendicular to each other with the optical axes of b. The blowing nozzle 20 is provided above the die plate 12 so as to be movable up and down, and descends to a position where it contacts the die plate 12 during blowing.
Further, the horizontal position of the blow nozzle 20 can be finely adjusted by, for example, a screw mechanism.

ル２２以外のものとすることもできる。 When adjusting the horizontal position of the blow nozzle 20, first the ball 22, which is a jig, is placed on the die plate 12 as shown in FIG. The ball 22 contacts the conical surface of the die plate 12, and the ball 22
The center position of the die plate 12 coincides with the center position of the die plate 12. In this state, the position of the ball 22 is measured by the position detector 14. That is, the light emitting section 16a and the light receiving section 18a measure the position in the X direction, and the light emitting section 16b and the light receiving section 18b measure the position in the Y direction. Next, the ball 22
is removed and the blowing nozzle 20 is lowered to the blowing position as shown in FIG. In this state, the position detector 14 similarly measures the position of the blow nozzle 20 in the X direction and the Y direction. Next, the difference between both measurement results is calculated, and the horizontal position of the blow nozzle 20 is adjusted so that the center position of the blow nozzle 20 coincides with the center position of the ball 22. The amount of adjustment in the X direction and Y direction at this time is indicated numerically as the difference between the two measurement results, so it is only necessary to adjust the position of the blowing nozzle 20 by this numerical value using, for example, a screw mechanism, which is very simple. It will be a lot of work. This allows the center position of the blow nozzle 20 to be adjusted to the die plate 12.
can be precisely aligned with the center position. In this embodiment, the ball 22 was measured first and then the blow nozzle 20 was measured, but it is clear that this order may be reversed. Further, in this embodiment, the ball 22 was used as the jig, but any other jig may be used as long as it matches the center position of the die plate 12, that is, it is a rotating body centered on the vertical axis. can.
