DRIVER FOR SPIRAL CONVEYOR SYSTEM

摘要

PURPOSE:To stabilize the feeding of belt by supporting the conveyor belt at the lowest stage in the slipping position of spiral section through a bele receiver of a guide drum thereby blocking the conveyor belt at the spiral section from lowering when the train lowers. CONSTITUTION:The conveyor belt 3 at the lowermost stage in the slipping position of spiral section is supported by a belt receiver 26 projected from a guide drum 18 and a belt supporting rail 30. Consequently, even if the supporting train 14 for entirely supporting the spiral section 6 of the conveyor belt 3 along a recess in a guide rail 13 is lowered at the slipping position to eliminate the supporting function for said spiral section 6, said spiral section 6 will never slip down resulting in stable feeding of belt.
