Abstract: The machine for manufacturing a construction panel has a plurality of clamping mechanisms (32) for holding fixed a subassembly including a plate-shaped heat insulating core (12) and upper and lower wire meshes (18,24) with predetermined gaps between them; a reciprocating carriage (44) mounted slidably in a longitudinal direction on a main frame (30); carriage driving mechanism (46) for moving the carriage (44) on the main frame (30) including a driving motor (140), an electromagnetic clutch (142) and a ball screw (144); a subassembly guide (34) for maintaining the predetermined gaps; first and second supporting member feeding and inserting mechanisms (36,38), each of which include feeding units (82) having hoppers (86) for discharging one-by-one a plurality of pre-cut first and second supporting members (26,28) and a plurality of inserting units (84), each of the inserting units including a pneumatic cylinder (92) having a piston rod (94) and a plunger (96) connected to the piston rod (94); and upper and lowe

Abstract: A supporting member feeding device utilized for manufacturing a construction panel of three dimensional structure, has gears whose teeth partially extend into an interior of an inclined wall of a hopper containing supporting members and rotating in an opposite direction from the direction of the ascending supporting members to smoothly discharge the supporting members toward a chute, and the supporting members discharged from the outlet of the hopper are kept at a predetermined distance by a spiral conveyor whose teeth extend into the chute through a hole of the chute forming member so as to forcibly and exactly feed the supporting members toward an inclined discharging outlet of the chute.
