DEVICE FOR TRANSPORTATION OF LONG-CUT MATERIAL Russian patent published in 1995 - IPC

FIELD: processing equipment. SUBSTANCE: device has housing with sides 1, two U-shaped roller conveyors 2, 3 arranged equidistantly in housing and drive shaft 4. Transportation rollers 5 of conveyors 2, 3 are driven ones. Secured on shafts of driven rollers are gear wheels 6, 7, 8, one wheel per shaft, grouped in layers in n parallel planes, where n = 1, 2, 3 ... N. Installed on drive shaft 4 are n identical gear wheels 9, 10, 11 on wheel being arranged in one of n planes. Gear wheels 6, 7, 8 of each layer are installed for engagement only with self-sustained endless flexible member 12, 13, 14. Each flexible member 12, 13, 14 couples in series and alternately gear wheels 6, 7, 8 of two roller conveyors. Flexible members 12, 13, 14 pass over gear wheels 6, 7, 8 of different roller conveyors from outer sides relative to pair of roller conveyors 2, 3. Inner U-shaped roller conveyor on section of its turning is formed by transportation rollers of smaller diameter, as compared with transportation rollers of outer roller conveyor. Relative arrangements of transportation rollers of roller conveyors 2, 3 on turning sections and straight-line sections are identical. Torque from drive 4 is conveyed to gear wheels 9, 10, 11 which set into motion flexible members 12, 13, 14 and the latter, drive gear wheels 6, 7, 8, which transmit rotary motion to transportation rollers 5. EFFECT: simplified design of roller driving mechanism irrespective of shape of roller conveyor. 3 cl, 7 dwg
