Description of the device
2.1
General
Afag Type HLF
-P
Linear Feeders are used to remove parts from upstream machines
and/or feed parts to downstream machines. Afag Linear Feeders are also used for
sorting parts, with due consideration of various criteria. Linear feeders are fitted in in-
dividual feeding units as well as in complex assembly systems.
The different types of Linear Feeders vary in size and application (see Table 1:
Technical data)
NOTE
The HLF-P may only be operated with the Afag Piezo controller PSG-
1. The PSG1 is adapted to the specific operating parameters of the
Piezo element. Operation with another controller will result in de-
struction of the Piezo element.

Functional description
HLF
-P
devices consist of two oscillating parts arranged on top of each other which
oscillate asynchronously. Slotted leaf springs connect these to a common base plate
at which the opposing oscillating forces virtually cancel each other out. The oscillat-
ing part on top is used as a structure (working weight) for attaching the feeder track.
The lower oscillating part is the counterweight.
A Piezo drive unit is mounted horizontally between the two oscillating parts. The fa-
vourable characteristics of the HLF-P linear conveyors are based on the high operat-
ing frequency which enables smaller amplitudes of oscillation and thus a smoother
conveyance with utmost precision. A further advantage of this device is the mass
balance between useful mass and opposing mass which eliminates free reactive
forces directly at the unit.
