（考案の対象、産業上の利用分野）
本考案は、溶融合成樹脂をダイスから押出し、
空中または水中でカツタ刃により切断し、ペレツ
トを作る装置の分野で利用される。[Detailed explanation of the invention] (Target of invention, industrial application field) This invention extrudes molten synthetic resin from a die,
It is used in the field of equipment that makes pellets by cutting with a cutter blade in the air or underwater.
本考案は、合成樹脂造粒装置のカツタ刃とダイ
スの間隙を調整する装置に関し、特に、カツタ刃
とダイスの間隙を直接測定できる装置に関する。 The present invention relates to a device for adjusting the gap between a cutter blade and a die in a synthetic resin granulation device, and more particularly to a device that can directly measure the gap between a cutter blade and a die.

をフエザータツチカツトという）。このように、
ダイスとカツタ刃との間隙は０〜0.2mm前後の微
少な範囲に保持する必要がある。(Prior art, its problems, and technical analysis) There is an optimal value for the gap between the die and the cutter blade. If the cutter blade and the die are in contact and the cutter blade is constantly polished with a surface-hardened die, pellets with a good cut shape can be obtained, but the cutter blade will wear out quickly and the cutter blade will need to be replaced frequently. It will stop happening. On the other hand, if the gap between the die and the cutter blade is too large, the cut shape of the pellets will be poor. The gap between the die and the cutter blade that allows a good cutting shape to be obtained varies depending on the type of synthetic resin.
For example, for low-density polyethylene, a gap of about 0.2 mm may be sufficient (such cutting conditions are called clearance cuts), but for polypropylene, it is desirable to have a gap of 0.02 mm or less (such cutting conditions are called feather touch cuts). . in this way,
The gap between the die and the cutter blade must be kept within a very small range of about 0 to 0.2 mm.

ればならない。 Furthermore, once the gap between the die and the cutter blade is set, it does not remain unchanged. Cutting the pellets gradually wears out the cutter blade itself. Furthermore, it is also affected by the operating environment, such as the gap changing due to the difference in thermal expansion of each part due to temperature changes around the die, and the gap changes due to the amount of deflection due to the propeller effect of the cutter blade due to changes in the rotation speed of the cutter blade. It is also affected by operating conditions such as Therefore, the gap between the die and the cutter blade must be inspected and readjusted periodically.
従来、ダイスとカツタ刃の間隙の調整はベテラ
ンオペレータの経験によるところが大であり、こ
の間隙を検知し調整できる装置が望まれるに至つ
た。 Conventionally, adjustment of the gap between the die and the cutter blade has largely depended on the experience of experienced operators, and there has been a desire for a device that can detect and adjust this gap.

理由は、カツタ刃とダイスの接触点しか直接確認
できないということにある。 Such a device is shown in Japanese Patent Publication No. 56-46966. In other words, an insulated electrode is embedded in the die so that its tip is flush with the die, the contact between the cutter blade and the die is detected, the position where the gap becomes 0 is confirmed, and the cutter is cut by a predetermined amount from that position. There is a contact confirmation type in which the blade is moved back to ensure the necessary clearance. However, in this contact confirmation method, (a) the gap is adjusted by the amount of mechanical retraction of the cutter blade from the point where the die and the cutter blade contact, so the gap changes due to wear of the cutter blade or changes in the operating environment and operating conditions. cannot be directly confirmed. Therefore, it is often necessary to bring the cutter blade into contact with the die. (b) When the gap is small, such as in a feather tatsuchi cut, the optimal gap cannot be maintained unless the cutter blade and die are brought into frequent contact, which causes the problem that the cutter blade wears out more quickly. The reason for this is that only the point of contact between the cutter blade and the die can be directly confirmed.

168640 proposes a direct confirmation type that uses a displacement sensor to directly measure the gap between the sensor and the cutter blade. However, even with this direct confirmation type, the following practical problems remain. There is a certain distance l between the die surface and the sensor end (or the detection end embedded in the sensor) (see Figure 1), and if this l is not subtracted, there will be no gap between the cutter blade and the die, but in this case, It is necessary to adjust and confirm this l in units of several hundredths of a millimeter. There is a problem in that it is difficult to do this with a general meter such as a dial gauge. or,
There is also the problem that l changes because the die surface also wears, albeit slightly. The reason for this is that the die and the sensor detection end cannot be set exactly on the same surface.

In other words, when the drive shaft is advanced and the cutter blade and die come into contact, the gap between the cutter blade and the non-contact sensor does not change despite the drive shaft moving forward due to the means that elastically holds the cutter blade on the drive shaft. This allows the zero point position to be confirmed.
Next, the positions of the die and the cutter blade are calculated using the detected zero point position as a starting point, and the cutter blade can be held at an arbitrary position.

By detecting the cutter blade, the position can be adjusted due to wear of the cutter blade or changes in the operating environment/conditions without the cutter blade coming into contact with the die.

A number of cutter blades 4 are attached on the circumference, and the signal from the non-contact sensor becomes a pulse signal 50.
The minimum value 51 of this pulse signal indicates the gap between the cutter blade 4 and the die. Place the cutter blade 4 against the die surface,
When approaching at high speed and then at low speed, the signal appears in the order a→b→c. However, when the cutter blade comes into contact with the die surface and is further advanced on the drive shaft 6, a section c→d in which the signal does not change is detected. Thereby, no matter how long the gap l between the die surface and the non-contact sensor surface is, it can be detected as a zero point between the die surface and the cutter blade. The position of the cutter blade is controlled based on a set position a certain distance away from this zero point. In the illustrated example, an upper and lower dead zone is provided for this set position, and the cutter position is moved when the dead zone exceeds this limit.
