Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-purpose coating machine that combines a top-feed type coater and a bottom-feed type coater so that the coater can be used according to the purpose of coating.

[Prior Art and its Problems] A multipurpose coating machine is known in which a plurality of coaters are combined to suitably correspond to a plurality of coating purposes.

In such a multi-purpose coating machine, for example,
As shown in FIG. 4, two types of top-feed type coaters, a comma coater 2 and a knife coater 8, are attached to the upper part of the coating machine body 4, and a gravure coater 3, which is a bottom-feed type coater, is attached to the lower part of the coating machine body 4. An operation floor 5 is arranged at the middle height of the coating machine main body 4.

Here, the top-feed type coater is a type of coater in which a coating resin is supplied from above, and the resin used generally has a high viscosity. Examples of this type of coater include the aforementioned knife coater and comma coater. The knife coater is a knife-shaped coater, as shown in FIG. 5, which is placed so as to be pressed against the base material 11 from above, and is suitable for coating the base material 11 thinly with resin. However, as shown in Figure 6, there are cases where a knife coater is placed on top of the roll (so-called knife over roll), and in that case, if the viscosity of the resin used is particularly high, the liquid pressure of the resin will cause the knife to coat the roll. There is a disadvantage that the coating thickness is not uniform due to bending. The comma coater was devised to eliminate this drawback, and is so called because the roll resembles the shape of a comma, as shown in Figure 7. It is used to coat resin thickly and evenly. Are suitable. However, it is not possible to apply a thin coating of resin by disposing the comma coater so as to press it against the base material from above as shown in FIG.

A bottom-feed coater is a type of coater that supplies coating resin from below, and the resin used generally has a low viscosity. An example of this type of coater is a gravure coater as shown in FIG.

In the multi-purpose coating machine shown in Fig. 4, the operator 10
stands on the operation floor 5 and operates the two types of top-feed coaters 2 and 8. When using the knife coater 8 on the back side, the comma coater 2 on the front side is used.
The drawback is that it gets in the way, makes it difficult to operate, and is highly dangerous. Further, when using the gravure coater 3, the operation floor 5 becomes an obstacle, and the operator 10 must operate from the back side of the coating machine main body 4.

An object of the present invention is to provide a multipurpose coating machine in which each coater is easy to operate and has high safety.

[Means for Solving the Problems] The multipurpose coating machine 1 of the present invention includes a top feed type coater 2 and a bottom feed type coater 3 on the upper and lower sides of the coating machine body 4, and the intermediate height of the coating machine body 4 is An operation floor 5 is arranged in the center, and the front end side 6 of the operation floor 5 closer to the coating machine main body 4 is connected to the base material 1 with respect to the rear end side 7.
