FIG. 2 is a temperature diagram of the sheet in the case of FIG. 1. In the figure, 1 is a die that extrudes thermoplastic resin into a sheet, and cools the sheet 3 by blowing pressurized air from an air knife 2. A first cooling roll 4 is rotatably supported by a side plate (not shown), and supplies cooling water thereinto to cool the sheet 3 uniformly.

る。 A second cooling roll 5 has the same structure as the first cooling roll 4, and nips the sheet 3 at a point with the first cooling roll 4 to polish both sides of the sheet 3. 6 and a cooling drum 8 in a water tank 7, the sheet 3 is sequentially cooled. Note that the second cooling roll 5 and the third cooling roll 6 are movable in the direction A and the direction C, respectively.

The sheet 3 is taken up between the nip roll 11 and supplied to a subsequent process device such as a tenter. Further, the nip roll 11 is movable in two directions.

る。 However, in FIG. 1, if the production amount of the sheet 3 extruded from the die 1, that is, the general feeding speed, or the thickness of the sheet 3 is changed, the nip point between the first cooling roll 4 and the second cooling roll 5 will change. Since the temperature of the sheet 3 at point A also fluctuates, it is necessary to adjust the cooling capacity of the first cooling roll 4 and the second cooling roll 5 in response to fluctuations in sheet temperature. Further, if it is impossible to adjust the cooling capacity of the first cooling roll 4 and the second cooling roll 5, it may not be possible to achieve a sheet temperature that allows both sides to be polished.

に、表面に皺が発生することがある。 Furthermore, when temperature changes are measured on surfaces A and B of the sheet 3 and the center of thickness C, as shown in FIG. 2, surface A is first rapidly cooled by the first cooling roll 4 (section).
However, when it is transferred onto the second cooling roll 5, the temperature rises rapidly and it re-melts (section), and the gloss formed by the first cooling roll 4 disappears and wrinkles appear on the surface. There are things to do.

Not only does it take a long time for the temperatures of B and center C to approximate each other, but also a third cooling roll 6 is required in addition to the first cooling roll 4 and the second cooling roll 5.
This has the disadvantage of increasing costs.

ある。 The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and in a double-sided gloss sheet forming apparatus for thermoplastic synthetic resin, a second cooling roll having a smaller diameter than the first cooling roll is used as the first cooling roll. The outer periphery of the roll is movable, a guide roller is provided to directly guide the sheet away from the second cooling roll into the water tank, and the water level of the water tank is variable, making it possible to polish both sides. It is an object of the present invention to provide a sheet forming apparatus that can easily form sheets.

FIG. 5 is a side sectional view showing a different operating state from FIG. 3.

抱き角θ1，θ2が可変となつている。 In the figure, 21 is a second cooling roll, and a water tank 22
It is rotatably supported on the upper part and nip the sheet 3 at a point opposite to the first cooling roll 4 to polish both sides of the sheet 3. Further, the second cooling roll 21
The first roller has a smaller diameter than the outer diameter of the cooling roll 4.
The outer periphery of the cooling roll 4 is movable in the direction of arrow H by a driving means (not shown), and the embracing angles θ 1 and θ 2 of the sheet 3 are variable.

じであるので、これらの詳細な説明は省略する。 22 is a water tank, and guide rolls 23, 24, 25
is rotatably supported, and the water surface level L is variable. The above is a description of the differences from FIG. 1, but the die 1, air knife 2, draining device 9, take-up roll 10, and nip roll 11 in FIG. Therefore, detailed explanations of these will be omitted.

次に作用を説明すると、ダイ１から押出された

浸漬されるまで昇温される（区間）。 Next, to explain the operation, the sheet 3 extruded from the die 1 moves from the first cooling roll 4 to the second cooling roll 21 via the nip point I.
The A side and the B side are cooled, and both sides A and B are polished. At this time, the surface A is rapidly cooled by the first cooling roll 4 (section) as shown in FIG. ).

水槽２２から出ると、再度昇温するが、シート厚
さの中心Ｃの温度に近似して行く（区間）。 Also, when immersed in the water tank 22, the temperature drops rapidly,
While moving through the guide rolls 23, 24, and 25 in the water tank 22, the temperature continues to decrease (section). Next, when the sheet comes out of the water tank 22, the temperature rises again, but the temperature approximates the temperature at the center C of the sheet thickness (section).

一方面Ｂはニツプ点イを過ぎると急速に降温

）。 On the other hand, the temperature of side B rapidly decreases after passing the nip point A, and the temperature decreases until the sheet 3 separates from the second cooling roll 21 (section '). Further, the temperature is increased until the surface is separated from the second cooling roll 21 and immersed in the water tank 22 (section ''). When immersed in the water tank 22, the temperature rapidly decreases to the same temperature as surface A, and thereafter, The state will be similar to that of surface A (section,
).

ところで第２冷却ロール２１から点ヘで離れ

れはシート３のヘ点における表面温度が180℃を

めである。 By the way, the surface temperature of the sheet 3 at the point where it leaves the second cooling roll 21 and enters the water tank 22 usually needs to be limited to 180° C. or less. This is because when the surface temperature at point B of sheet 3 exceeds 180°C, the cooling water near point T boils, causing sheet 3 to boil.
This is because there is a risk that a pock-like pattern may appear on the surface of the product.

き角θ2は大となる。 In this embodiment, the above-described embrace angle θ 1 is selected to be an appropriate angle for cooling the sheet 3 and obtaining a double-sided glossy sheet. If the extrusion rate is constant, the sheet thickness tends to be large and the hugging angle tends to be large. The embracing angle θ 2 changes as the embracing angle θ 1 changes, and when the embracing angle θ 1 is large, the embracing angle θ 2 becomes large.

に、水面レベルを上昇させて、これに対応させる
（第４図区間のシートＡ面の冷却カーブ参照）。 On the other hand, it is necessary to prevent the sheet surface temperature from increasing by guiding the sheet into the water tank at a temperature below which the sheet leaves the second cooling roll 21 at a temperature at which the sheet does not re-melt and wrinkles do not occur. For example, when the second cooling roll 21 in FIG. 3 is moved in the direction of arrow H, the distance from point A to point T becomes longer. Therefore, in order to minimize the distance from point A to point T in Figure 3, the water surface level is raised to accommodate this (see the cooling curve for the sheet A side in the section in Figure 4).

を容易に成形できる。 Since the present invention is configured as described above in detail, the second cooling roll is moved around the outer circumference of the first cooling roll as shown in FIG . By adjusting L and suppressing the rise in the surface temperature of the sheet, the surface temperature of the sheet at point T can be limited to 180°C or less, making it possible to adjust the cooling capacity of the first cooling roll and the second cooling roll. , the time required for the temperatures of surfaces A and B and center C to approximate each other is reduced, and a double-sided glossy sheet can be easily formed.

可能としてもよい。 Furthermore, by moving the second cooling roll to the left side of the first cooling roll as shown in Fig. 5, the embrace angle θ 1 of the sheet of the first cooling roll can be increased. It becomes possible to make the size smaller, and cost reduction is achieved. Since the roll diameter of the second cooling roll is smaller than the roll diameter of the first cooling roll, the distance from which the sheet leaves the second cooling roll to entering the water tank can be shortened, thereby reducing the re-rise of the sheet surface temperature. can. Furthermore, since the path length between rolls can be shortened in an unstable state where the sheet is not completely solidified, stable molding can be achieved. Note that the second cooling roll 2
1. The water tank 22 and the guide rolls 23, 24, 25 may be integrally configured so that the outer periphery of the first cooling roll 4 can be moved.
