Title: Intermediate friction belt drive for bulk conveyor - has vertically adjustable support rollers governed by load sensors
Inventor: JUENGEL HEINRICH DIPL ING
IPC: B65G23/14
Filed: 1974-03-14
Abstract: A conveyor belt for bulk material is equipped with intermediate friction drive units. The drive consists of a friction belt which is placed between the upper and lower conveyor belt section. The power that can be transmitted through the friction drives is a function of the coefficient of friction and the load on the conveyor. By using vertically adjustable support rollers, the tension in the drive belt and the contact area between drive belt and drive rollers can be varied. Sensors which detect the conveyor load and any slip that occurs between drive belt and conveyor are used to govern the power transmission of the intermediate drive units. Their size and number can therefore be kept to a minimum.
