CONVEYOR Russian patent published in 1995 - IPC

FIELD: materials handling; continuous transportation of loads. SUBSTANCE: conveyor has roller support 1 with drive member, roller support 2 for tensioning belt 3, and roller supports 4 for supporting belt 3. Belt 3 is wound inside frame 5 over screw line in form of tube with belt edges tightly fitting each other. Belt moves inside frame along screw line forming transportation channel for load. Frame 5 is arranged along conveyor axis. To increase strength of frame, its members are connected by rods 6. To provide minimum clearance between belt coils, side rollers 7 holding belt 3 from sides are installed at the beginning and at the end of conveyor. Rollers 7 are secured on conveyor frame 5. Roller supports 4 are secured on frame 5 square to belt coils. With drive of roller support 1 switched on, belt 3 moves along screw line, thus transporting load inside. When loose load is transported, it moves from one coil of belt to the other, thus being conveyed to discharge point. Unit loads held by belt are transported without slipping and rolling. EFFECT: enlarged operating capabilities. 3 cl, 2 dwg
