ABSTRACT:
Expandable powered conveyors featuring a number of roller power motors located externally of the rollers. The conveyors include a pair of lazy tong trusses which may be supplemented, as desired, by telescoping rigid frames, leg structures or other structures. The motors are mounted between the trusses so that their drive pulleys are located substantially coaxial to the middle connection points of the scissor bars in the trusses and thus maintain a substantially constant distance from rollers connected to those scissor bars. Drive belts connect the motor drive pulleys to power such rollers. The conveyors also include a number of transfer pulleys which are also mounted substantially coaxial to corresponding middle connection points of the trusses. A single motor may thus power one or more rollers directly, and other rollers indirectly via motor drive belts and transfer drive belts. Use of a number of motors allows grouping of rollers into zones with the same advantages enjoyed in more expensive internally powered roller conveyors, but with greater reliability, ease of maintenance and savings and expense. Among those advantages are independent control of roller zones for accumulation of product and other purposes.
