Function
The spring feeder facilitates the disentangling and feeding of springs. With an airflow, which
is to turn-on or turn-off in a determined rhythm, the springs are spinning in the housing and
disentangled. Springs that are blocked in the output are blown back into the housing by the
airflow. The blown-in air in the housing, which can only escape by the output, conveys the
springs into the conveyor tube. With a supplementary airflow the springs are conveyed to the
output. The control unit is equipped with an automatic cut-in device that switches on the
spring feeder only as required. A ring initiator may effect scanning. Units that are equipped
with a hopper can be filled up automatically. The tappet of the hopper conveys the springs on
the chute by means of a lifting movement in front of the slide. If the drum is empty (is
controlled by a light barrier), the slide is opening automatically; the springs slide into the unit.
As soon as the slide is closed, the unit begins again to work. Simultaneously and without loss
of time, the chute is filled up again with springs by an exactly defined quantity of lifting s.
The process begins again.
Remarks:
The unit is factory set from Meto-Fer for the corresponding springs.
The springs must be clean and dry.
The unit is supplied with a matching nuzzle, tube mount and 2 meter tube.
Operation Instruction
Switch off the unit=> push up the toggle switch
Fill up the drum with springs; ca. 0.3- 0.5 Liter
Connect current supply=> 24V DC
Check slide to make sure it is properly closed
Connect compressed air, set approximately 6 bar
Switch on the unit=> push down the toggle switch (green light on)
If all is switched on correctly and the ring initiator is not initialized, the unit will automatically
start functioning

Setting of timer and counter
With the integrated control system the Timer T1 (spinning time), T2 (blowing time), T3 (pause
1), T7 (pause 2) as well as the Counter C1 (light barrier) and C2 (filling up) can be changed
during working of the machine. Immediately after confirmation, the changed parameter is
taken on, the optimation becomes very easy and has to be carried out in eight steps. If at the
same time more than one timer or counter are being matched, step 7 is always followed by step
4 and continues as usual (from top to bottom). For leaving the menu, press ESC.
