The foamable core material is cured by being heated from hot air flowing through the hot air passage 43 for a predetermined time, for example, 25 minutes, under an atmosphere of a predetermined temperature, for example, about 60 ° C., based on a control signal from the CPU 5. The laminated core P is formed by converting the core material into resin.

Thereafter, the flat plate 1 (temporary assembled panel Po) is similarly carried into the intermediate molding machine 40 and the rear molding machine 40 to form the laminated panel P.

After forming the laminated panel P after a predetermined time has elapsed in the molding machine 40, the pressurization is released, and then the lifting / lowering means 50 is lowered to move the lifting / lowering means 50 to the position of the lowermost mounting shelf 42. The carry-out part 62 is moved. Then, the hooks 99 of the unloading member 98 are hooked on the upright wall 1b of the flat plate 1, and the unloading member 98 is moved to the unloading unit 62 side.

The flat board 1 (the laminated panel P) is carried out to the carry-out section 62 by the operation of the carry-out conveyor 68. The flat board 1 (laminated panel P) carried out to the carry-out section 62 is carried out by the carry-out conveyor 68 onto the upper conveyor 80B of the conveying means 80.

After unloading the flat plate 1 (laminated panel P) on the lowermost mounting shelf 42, the lower conveyor 80 of the lifting / lowering means 50 is moved.
The flat board 1 (temporary assembly panel Po) is carried in on A. In this state, the lifting / lowering means 50 is raised, and the lower loading section 61 is moved to the position of the lowermost loading shelf 42 and the upper loading section 62
Is placed at the position of the second shelf 42. Then, the flat plate 1 (laminated panel P) on the second-stage mounting shelf 42 is unloaded to the unloading section 62 by the unloading member 98 and the unloading conveyor 68 in the same manner as described above. The flat board 1 (temporary assembly panel Po) on the unloading section 62 is
5 and the carry-in member 91 are carried into the lowermost mounting shelf 42.

Hereinafter, similarly, the mounting shelves 42 of the third and subsequent stages
Of the flat board 1 (laminated panel P) from the pallet and the loading of the flat board 1 (temporarily assembled panel Po) to the second and subsequent mounting shelves 42. Therefore, the unloading of the laminated panel P and the temporary assembly panel P
o can be carried in at the same time, and the molding machine 40
Can be carried out of the molding machine 40 in the order in which they are carried in.
Such loading and unloading operations are performed by each molding machine 40 and the lifting / lowering means 5.
Since it is set to 0, the productivity of the laminated panel P can be improved.

After the laminated panel P formed by the front molding machine 40 is carried out as described above, the laminated panel P is carried out in the order of the intermediate molding machine 40 and the rear molding machine 40, The molding machine 40 in front of which the laminated panel P has been carried out
The flat board 1 (temporary assembly panel Po) is sequentially carried in from. Therefore, a large number of laminated panels P can be continuously formed.

Flat plate 1 conveyed to upper conveyor 80B
(Laminated panel P) is separated by a transport unit 80 into a separation unit 70.
A, the stacked panel P is sucked by suction by the suction pad 76 of the separating means 70 in the separating section 70A, and is transferred to the stacked panel carrying-out section 62. On the other hand, the separated flat plate 1 is transported to the flat plate setting section 10 for a panel to be manufactured next.

In the above-described embodiment, a case has been described in which a plurality of elevating means 50 are provided in front of a plurality of, for example, three molding machines 40. However, one elevating means 50 is moved in front of each molding machine 40. By forming it as possible, the number of components of the manufacturing apparatus can be reduced.

In the above embodiment, the case where the flat board 1 (temporary assembly panel Po) is carried in only by the carrying-in section 61 of the lifting / lowering means 50 has been described. By providing the function, when the flat board 1 (temporary assembly panel Po) is first loaded into the molding machine 40, two sets of flat boards 1 (temporary assembly panel Po) can be loaded simultaneously, and the loading time Can be reduced.
