Operating instructions 

The first step in adjusting the linear feeders is always to balance the masses and then to 
adjust the natural frequency. 

 

4.1

 

Feeder track design 

The  linear  tracks  must  be  unyielding  so  that  the  transport  pulses  generated  by  the  unit 
are  fully  transferred  to  the  work  pieces  and  no  superimposed  natural  vibration  can  ad-
versely  affect  the  transport  process.  This  requirement  has  priority  over  mass  reduction 
measures. The preferred material for linear tracks is tool steel (e.g. 1.2842, 90MnCrV8). 
Linear  track  design  should  adhere  to  the  useful masses  specified  in  chapter  2  Table  1: 
Technical data 
and Table 4: Obligatory values for the working weight 

The following size ratio should be aimed for with regard to the feeder track cross-section:

The  recommended  dimensions  are  listed  in  Table  3: 

Linear  track  dimensions

.  The  di-

mensions  are  for  one  vibrating  section  and  can  be  applied  to  each  of  the  two  vibrating 
sections.

Balance of weights 

The  oscillating  forces  in  the  base  plate  of  the  Afag  Linear  Feeder  are  compensated  al-
most completely due to the principle of opposing oscillations (push-pull). This balance of 
oscillating forces is however only achieved if: 

1.

  The  working  weight  and  the  counterweight  are  balanced  as  closely  as  possible.This 

means  that  the  working  weight  and  the  counterweight  are  equal.  The  working  weights 
specified for respective sizes are listed in Table 4 below. The working weight is the total 
weight  of  all  components  attached  to  the  mounting  plate  including  the  side  plate.  The 
balance of weight is verified by simply weighing the working weight. 

2.

 The centre of gravity of the working weight is located in the range represented in  Fig-

ure 3. 

 

Both conditions have to be taken into consideration at the construction stage of the feed-
er  track.  An  optimal  balance  of  weight  is  achieved  when  almost  no  residual  vibrations 
can be detected in the substructure.
