のフィルム巻製品を得る技術に関する。Metal Foil 9 Relates to a method for winding synthetic resin films such as webs, sheets, films, etc., and a quality control method for rolled products. More specifically, when winding a web or sheet (hereinafter referred to as film) into a roll, the relationship between the winding length of the film being wound and the number of sheets stacked in the roll is measured, and a constant winding length is determined. Whether the measured value of the number of laminated layers at the time of passing is within the acceptable range of the relationship between the standard winding length and the number of laminated layers for a good product, and the winding of the film according to the difference from the standard value. This invention relates to a technique for obtaining a substantial film-wound product by modifying conditions, that is, controlling winding tension and winding contact pressure.

た。2) The problem to be solved by the invention The rolled film product is generally manufactured into a roll by slitting a wide and long roll of original film into a predetermined width and winding it into a predetermined length. There was no means to control the winding condition during the layering process from the core to the outermost layer, and when unraveling with a special camphor tree, defects were exposed from the inner layer, resulting in a large amount of loss.
内層に欠陥が発現する原因は、８層する際のフィルム層
間圧巻込まれる空気層の厚さ斑であり、良好な巻状態を
保つ為には積層過程の空気層厚さを精度よく調整するこ
とが最大の要件である。The cause of defects in the inner layer is the uneven thickness of the air layer that is trapped between the 8 film layers, and in order to maintain a good winding condition, the thickness of the air layer during the layering process must be adjusted with precision. is the biggest requirement.

れてくることからその影響は増大する結果となる。The most important thing for the winding quality of film-like materials is adjusting the thickness of the air layer drawn between the layers during the lamination process, and in any winding mechanism, this is controlled by tension and contact pressure conditions as a means of determining the winding quality. However, since many products are processed at the same time or rolled up repeatedly, it is difficult to avoid small fluctuations in the conditions of individual winding rolls. As the values are added, the effect increases.

縦シワ欠陥が発生することが知られている。If the air thickness between the eyebrows is more than the standard value, excess air will be released after hoisting, resulting in horizontal wrinkle defects when unraveling, and if the air thickness is less than the standard value, the air will cause elasticity. It is known that the effect is lost and vertical wrinkle defects occur in areas where the thickness distribution in the width direction is thin.

However, this method does not comprehensively control the entire process from the start of rolling to the winding of the rolled product (it is a control at individual points in time, and cannot be applied to quality control of the rolled product as a whole). be.

品質を連続管理するものである。4) Structure of the Invention The method of the present invention involves actually measuring the number of laminated sheets (rotation speed of the winding shaft) from the beginning to the end of each film roll wound into a roll, and taking out the number of laminated sheets for each fixed winding length. Comparing with the standard number of laminated sheets for good winding quality, the winding between the start of winding and the end of winding =

という状態にある。In the winding management method of the present invention, when the number of sheets measured when passing through a predetermined winding length is compared with the standard value, it is found that when the number of layers is large for a 700-roll film, Because the diameter is small and the interlayer air thickness is thin, vertical wrinkles are likely to occur.When the number of laminated layers is small...The winding diameter is large and the air thickness is thick, so the air escapes over time and horizontal wrinkles occur. It is in a state where it is easy to do.

である。Therefore, the present invention (first invention) increases or decreases the tension of the film during winding and the contact pressure (pressure) of the roll-shaped object, so that the relationship between the winding length and the number of laminated layers matches the standard value. It is something to control.

A film winding device that adjusts the winding tension of the film during winding or the pressing force of the film laminated in a roll shape by increasing or decreasing the winding tension of the film during winding or the pressing force of the film laminated in a roll according to the difference between the measured value and the standard value. This is the way to take it.

に調節するものである。To explain this first invention, a film is rolled into a rolled product in a state shown in the embodiment shown in FIG. 1 horizontally. The film 1 is pressed by two rolls 3 when being wound onto a film roll 2. The air value between the film layers is adjusted based on the conditions of this pressing state and the winding tension of the film. During winding, the sensor 4, which is a means for measuring the number of layers, measures the number of layers on the side of the film roll, and the counter 5 clearly indicates the number of eight layers. FIG. 2 is a graph showing the film winding length (product winding length) and the number of laminated sheets. By specifying the film thickness, winding hardness, and air space between the film layers, the standard winding length and product J-number are determined. FIG. 2 shows an upper limit value 7 and a lower limit value 6 (lower limit number of laminated sheets) as management standards. A good film roll has a value close to the standard value, which is an average value between the upper limit value and the lower limit value. During the winding process, if the number of laminated layers in a particular winding length is too small, increase the film winding tension (slightly change the winding speed) or increase the pressure load of the tube roll to increase the contact pressure. The winding length and the product j-number are adjusted to standard values using a winding method or a combination of these methods.
