本発明はカレンダ成形時において、カレンダパンク量、
即ち、カレンダロール上における原料溜り量の制御方法
に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for controlling the amount of calender puncture,
That is, the present invention relates to a method of controlling the amount of raw material accumulated on a calender roll.
カレンダ成形においてカレンダロール上ヘノ原料を適正

レンダロール上の溜り量を目視あるいは、光切断によら
ない撮像法で測定していた。In calender molding, it is important to control the quality of the product by keeping the appropriate amount of raw material on the calender roll. Conventionally, the amount of accumulation on a calender roll was measured visually or by an imaging method that does not involve optical cutting.
特に原料が低位レベル即ち少なくなった場合、カレンダ
ロールに隠れて見えない、あるいはレベル検出不能など
の問題があった。In particular, when the raw material is at a low level, that is, when the raw material becomes low, there are problems such as it is hidden behind the calender roll and cannot be seen, or the level cannot be detected.
本発明は上記欠点を解消し、低位レベルま、でレベル検

とを目的とする。The object of the present invention is to eliminate the above-mentioned drawbacks, detect levels down to low levels, and supply an appropriate amount of raw material onto the calender rolls.
本発明は上記目的を達成するために、スリット光を垂直

ことを特徴とするものである。In order to achieve the above object, the present invention irradiates the slit light in the range of vertical to 30 degrees, and irradiates the slit light in the range of 15 degrees to
The method is characterized in that a light section of the irradiated light is imaged by an area sensor camera at an angle of 45°, and the raw material accumulation on the calender roll is measured, so that the appropriate amount of raw material is supplied onto the calender roll. It is something.
以下、本発明の一実施例を図面について説明する。 An embodiment of the present invention will be described below with reference to the drawings.

正レベルの原料供給が可能になる。Since the illuminator 4 is installed so as to illuminate the center of the calender roll, it is possible to measure down to the low level of the resin material between the rolls. Furthermore, since the imaged slit image is subjected to image processing and extraction for the slit edge contour, the resin raw material level can be measured at multiple points of the roll length address. Further, by configuring the system so that a slit image can be captured by one or more sensor cameras over the entire length of the roll, the level of the resin raw material over the entire length of the roll can also be measured. By feeding back these measurement data to the raw material supply device, it becomes possible to supply raw materials at an appropriate level.

範囲に設定される。FIG. 2 is a drawing showing a comparison with the conventional method. By setting the angle of the area sensor camera 3.3A at 15° to 45°, it is possible to measure the raw material level to a lower level than in the conventional method where the imaging angle F without light cutting is large. The floodlight is set in the range of θ° to 30° so that it can illuminate even low-level raw materials.

が、製品フィルムの品質管理上望ましいとされている。It is considered desirable for the quality control of the product film to control the supply level of the resin raw material to the calender roll from σAXI/3 to 0AX2/3 in FIG.

It becomes possible.
