Description

[Detailed description of the invention] [Industrial application field]

The present invention is an apparatus for manufacturing a sanderch panel in which a synthetic resin foam is filled between the outer skins, in which a side conveyor that can be replaced in accordance with the thickness of the sanderch panel can be stored.

[Prior art]

Conventionally, upper and lower strips such as metal plates are supplied between upper and lower conveyors, and in this upper and lower conveyor section, foamed synthetic resin is injected and foamed between the upper and lower strips to create a synthetic resin foam between the upper and lower strips. Devices are known for producing sanderch panels filled with.
In this case, in order to prevent the foamed synthetic resin from leaking outward from between the side edges of the upper and lower strips when foaming, paper, synthetic resin sheets, or metal foil should be placed between the side edges of the upper and lower strips between the upper and lower conveyors. A side conveyor is placed between the side edges of the upper and lower conveyors in order to supply side sealing material such as packing material, and to correctly position and convey this side sealing material between the side edges of the upper and lower belt plates. Ta. In other words, the foamed synthetic resin injected between the upper and lower strips at the upper and lower conveyor portions foams, but the area between the ends of the strips is closed by the side conveyor via the side sealing material, so it leaks outward. In this case, the side sealing material is adhesively integrated with the synthetic resin foam by the self-adhesive force of the foamed synthetic resin. Incidentally, a sanderch panel is formed using the above-mentioned device, and this type of sanderch panel has a wall thickness of, for example, 22 mm or 35 mm.
To manufacture sanderch panels with different wall thicknesses, there are many types such as mm, 45mm, 60mm, 100mm, 120mm, etc.
At least one of the upper and lower conveyors is moved in the vertical direction to change the distance between the upper and lower conveyors, and the side conveyor is replaced with one having a different thickness in the vertical direction.

[Problems to be solved by the invention]

In the conventional example described above, the side conveyor that was replaced to manufacture sandwich panels with different wall thicknesses is currently left as is and piled up on the floor of the workshop. However, piling it up on the floor of the workplace is not only a hindrance to the work, but also poses a safety problem.
Furthermore, since there are many types of side conveyors with different thicknesses piled up in the open, if you want to replace them,
There was a problem that it was difficult to find a side conveyor of the required size, and it was time-consuming to take it out.
