3. Leaf springs β. Inclination of leaf springs
5.2 Functional description of the LF
The LF is a module which transforms electromagnetic oscillations to use them
to feed component. The magnet, connected to the support, creates a force
which attracts reps. releases the oscillating plate dependent on the oscillation
frequency of the power supply.
As the magnetic anchor is connected to the feed bowl, it also follows the
frequenting movement. As a result, the conveyed material, due to the angle of
inclination of the leaf spring, lifts off with each oscillation and performs small
jumping-off movements in a direction perpendicular to the leaf spring plane.
On a cycle of the 50Hz alternating current supply, the magnet achieves twice its
maximum pulling force while this is independent of the direction of current flow.
The magnet thereby produces an oscillating frequency of 100 Hz. This 100 Hz
oscillation is necessary to achieve a smooth or gentle transport.
With heavy or large workpieces however, it is necessary to use an oscillating
frequency of 50 Hz. A half wave of the mains supply is thereby blocked.

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 linear feeder. This can be achieved through suitable
protective measures (e.g., enclosure, light grid).
When the system is running in special operating modes, it must be ensured that
there is no danger to the operator.
The system operator is responsible for the installation of the linear feeder in
a system!
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
Installation instructions 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 power supply before assembly and disassembly work and
when making changes to the installation!

6.2.2 Fastening the module
The LF is firmly bolted to the foundation by means of the holes drilled in the
floor. For the LF9, two screws are inserted from below. With the help of mounting
plates (chap. 3.3.1), optional mounting from above is possible.
Fig. 4 Attachment of the LF11 (exemplary illustration)
For operation, the linear feeder must always be mounted on a base that is
sufficiently dimensioned for the intended mass. The base construction must be
designed to be vibration-resistant (slab or block construction) to be able to
absorb the vibration forces that occur.
Mounting holes
