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 lower electric welding mechanisms (4) for spot welding the longitudinal wires of the upper and lower wire meshes (18,24) with the first and second supporting members (26,28) to form a finished construction panel (10).
