5.1 Structure of the vibrating refill hopper
Fig. 3 Design of the NVB (vibratory refill hopper)
5.2 Functional description
The vibrating refill hopper (NVB) is used to storage bulk materials. The transport
movement is generated by vibration.
Electromagnetic vibrations are converted in the NVB to store and convey piece
goods. The parts are moved in the conveying direction by micro-jumps.
The vibrating refill hoppers NVB consist of a vibrating trough and an Afag linear
feeder from the HLF-M series.
The HLF consist of two vibrating parts arranged on top of each other which
vibrate asynchronously. Slotted leaf springs connect these to a common base
plate at which the opposing vibrating forces virtually cancel each other out.
The upper vibrating part is used as payload for fastening the conveyor rail. The
vibrating part at the bottom forms the counterweight. A magnet system
(armature-magnet core) is installed horizontally between the two vibrating parts.
Due to the adjustable mass compensation between the payload and
counterweight, the free vibrating forces can be eliminated directly in the unit.

6 Installation, assembly and setting
For safe operation, the module must be integrated into the safety concept of the
system in which it is installed.
During normal operation, it must be ensured that the user cannot interfere with
the working area of the module. This can be achieved through suitable
protective measures (e.g., enclosure, light grid).
6.1 Safety instructions
No liability for damages can be assumed for damages caused by improper
installation on the part of the operator.
Observe the safety instructions in chap. 2 "Safety instructions" of this
manual as well as the instructions in chap. 6.3.
WARNING
Danger! Risk of electric shock!
If work on electrical components is required, ensure that the work is carried
out properly, failure to do so will cause serious or fatal injuries.
Work on the machine's electrical equipment may only be performed by
skilled electrician or trained personnel under the supervision of a skilled
electrician in accordance with all relevant electrical regulations.
Disconnect the supply voltage before starting work!

Ensure that the protective earthing of the power supply is in perfect
condition.
CAUTION
Danger of injury by moving components!
The module must not be started up by unauthorised persons during
installation and adjustment work. Limbs can be crushed by moving parts and
cause serious injuries.
Attach clearly visible signs before starting work!
