  • Spiral conveyor drive control and lubrication
    Patent number: 11008173
    Abstract: The bottom tier (24) of a conveyor belt (22) arranged in a spiral stack (26) is supported by and driven by inner and outer drive chains (28) and (30). The inner and outer drive chains are supported on and ride along support rails (32) and (34). The inner and outer drive chains are driven by a drive system (35) composed of inner and outer drive systems (36) and (38), each including a drive motor with a drive gear engaged with the inner and outer drive chains. Each of the motors is controlled by a separate variable frequency drive unit (114) and (116) which in turn are controlled by a control system (44). The control system (44) also controls the operation of a lubrication system (40) that supplies lubricant to the drive chains.

  • SUPPORT RAIL FOR A SPIRAL CONVEYOR
    Publication number: 20200283031
    Abstract: A longitudinally curved support rail (56) for supporting and moving a drive chain assembly (52) at the base of a spiral conveyor belt (34) to drive the bottom tier (30) of the spiral conveyor belt while being supported by the support rail. The support rail including an upright web section (80) and a support flange (78) cantilevered outwardly from the web section to provide a platform or shelf to support a chain drive assembly (52), thereon during travel of the chain drive assembly along the support rail.
