The “classic,” low-cost solution for a machine tool chip conveyor is usually a model that features a top-mounted gearmotor, a torque limiter (slip clutch), and a drive chain that connects the two. On budget conveyors, the gearmotor is wired directly to an on/off control. There are several limitations to this setup.
An improvement to the “classic” chip conveyor is to add a push-button control box, making the conveyor safety feature the torque limiter. One improvement the push-button control box offers is the ability to have the conveyor run in both forward and reverse, assisting operators in clearing jams. If the jam is not cleared, however, the operator will still need to shut down the conveyor. An emergency stop (E-Stop) button is also added for additional safety.
Due to the ever-increasing demand for improved chip conveyor functionality and efficiency, Hennig has offered VFD's (Variable Frequency Drives) as a standard for most new conveyor products for several years.
Hennig standard conveyors feature a direct drive motor with a VFD control, providing many advantages over the “classic” solution:
Variable Frequency Drive (VFD) with a yellow emergency stop button stops the conveyor only.
Variable Frequency Drive (VFD) with a red emergency stop button stops the conveyor and the machine.
