Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for producing a resin sandwich type metal plate containing a conductive filler.

[Prior Art and Its Problems] It is known that iron powder, nickel powder, stainless powder, etc. are added as a conductive filler into the resin of a resin sandwich type metal plate to impart conductivity and ensure weldability. (JP-A-59-145142, etc.). Such a conductive filler is arranged on the entire surface, and the weldability is good in any range (position).

However, for example, in the case of manufacturing a container-shaped part or the like, a body is formed, flanges are formed above and below the body, and the flange and another member are welded. In such a case, the conductive fuller-added resin may be arranged at both ends in the steel sheet rolling direction, and the filler-free resin may be arranged in the central part. That is, if the filler-added resin is placed in the non-welded area, the adhesiveness between the metal plate and the resin, and the damping property are a little inferior to the placement area of the filler-free resin, which is disadvantageous and the filler is wasted. Since it is used, especially if it is expensive such as nickel powder, there is a drawback that the cost is significantly increased.

[Means for Solving the Problems] The gist of the present invention is that a resin supply path is divided into a central portion and both end portions in the resin table width direction, and a conductive filler-added resin circuit is provided for these supply paths. A conductive filler-containing resin sandwich type in which a conductive filler-free resin circuit is configured between resin tanks, and a separator is placed at the boundary position between the resin coater roll and the pick-up roll It is in a metal plate manufacturing device.

[Operation] Thus, for example, in the case of imparting weldability only to the upper and lower parts of a container-shaped part, the resin with additive of conductive filler is supplied to both ends of the resin table from the resin tank, and the resin with no filler is added to the center. Supply from another resin tank, applied to one metal plate surface through the pickup roll and coater roll, each surplus resin, without mixing with each other by the separator placed between the pickup roll and coater roll, Return to resin tank. In addition, when imparting weldability to the central portion in the metal width direction such as connecting parts to each other, supplying conductive filler added resin to the central part,
Supply resin without filler to both ends.

Further, various forms can be adopted, such as supplying the conductive filler-added resin to both ends and the central part and supplying the filler-free resin between the both ends and the central part.

[Examples] Next, examples of the present invention will be described.

In FIGS. 1 and 2, a resin tank 1 is filled with a conductive filler-added resin 2, and a supply circuit 4 is provided via a pump 3.
To the resin table 5 Masu 6,6a arranged at both ends in the width direction
Resin 2 through a branch supply path 7 to the cells 6, 6a
It is picked up from the pick-up roll 8 and applied to both ends of the metal plate (band) 10 through the coater roll 9.
Excess resin 2 is passed from the measure 6 through the gutters 11 and 11a to the circuit 4a.
Return to resin tank 1.

On the other hand, another resin tank 1a is filled with conductive filler-free resin 2a, and the resin 2a is supplied from the supply circuit 7 to the table 5 at the widthwise central portion of the resin table 5 via the pump 3a from the supply path 7a to pick up. The roll 8 is picked up and applied to the central portion of the metal plate (band) 10 via the coater roll 9, and then the applied resins 2 and 2a are dried to apply another metal plate (band) (not shown) to the resin. The resin sandwich type metal plate is arranged on the surface and pressure-bonded.

Then, the surplus resin 2a supplied to the central portion of the table 5
Drops into the container 13 and returns from the container 13 to the resin tank 1a via the circuit 12a.

In order to prevent the conductive filler-added resin 2 at both ends in the width direction from the pick-up roll 8 and the coater roll 9 and the conductive filler-free resin 2a in the central part from falling into each other, the separator 14 is filled with a filler as shown in the figure. It is arranged at the boundary position between the unadded resin 2a and the filler-added resin 2, that is, it is arranged at both ends in the width direction of the gutters 11 and 11a as shown in FIG.

As described above, the resin supply passages 7 and 7a are divided into the central portion and both end portions in the width direction of the table 5, and the resin 2, 2a circuits 4, 4a 12 and 12a are connected to the supply passages 7 and 7a. , 1a, and the separator 14 is disposed at the resin boundary position between the pickup roll 8 and the coater roll 9.

[Advantages of the Invention] By doing so, the application position of the conductive filler-added resin and the additive-free resin can be arbitrarily changed in the width direction of the metal plate, and the resin sandwich type metal plate is provided with the weldable portion according to the manufacturing member. Therefore, the adhesion between the metal plate and the resin is improved, and the workability is improved.

Further, when the vibration damping resin is used, the vibration damping property can be improved, the amount of the filler used can be reduced, and the cost can be reduced. Further, upon application, it is possible to bring about an excellent effect such that the excess resins can be reused without being mixed with each other.
