In a vibrator bowl are springs which move by vibrations on spirals to the exit on top. To avoid that more than one spring is transported to the exit there is an adjustable chicane integrated. The feeding speed can be regulated electronically. Because springs have the bad behavior to tangle they may pass the chicane. To avoid that tangled springs reach the exit there is a sensor. This sensor detects single springs or tangled springs. That the sensor can detect single or double springs with small wire diameter as well the sensor must have an adjustable distance to the springs. To adjust easily the distance to the spring a micrometer screw is fixed at the end of the sensor. To find the correct distance a lightband composed of ten LED segments is used as tuning aid. The correct distance to let only pass one single spring can be adjusted by the distance to the spring and the zero signal of the sensor.
When two hooked springs pass the sensor the electrical output of the sensor rises and an indicator light flashes. At the same time a pneumatic valve is opened and an airblast blowes the tangeled springs off the feeding system and back into the vibrator bowl. Only single springs reach the exit of the vibrator bowl. A ringsensor can indicate whether springs should be feed in the following stock tube or whether it is full. As soon as the storage tube is full a yellow lamp flashes to indicate „storage full“ and the vibrator bowl is switched off. When the ringsensor detects no spring the feeder is switched on to continue filling the storage tube.
The feeder requires 220 V 50 Hz and compressed air with 6 bar pressure.

There are 3 different sizes of bowls:
FZ-2 vibrator dia 200 mm, springs de 2 mm to 6 mm
FZ-3 vibrator dia 300 mm, springs de 4 mm to 12 mm
FZ-4 vibrator dia 450 mm, springs de 10 mm to 25 mm

With the detangler EW 1 it is possible to detangle parts which could not be dentangled before.
- for cylindrical or conical compression springs
outside diameter: appr. 2 mm - 10 mm
length: appr. 35 mm
diameter of wire: 0,3 mm - 1,0 mm

Please contact us if you have other parts or send us some samples for a test.

Max. filling capacity 0,1 l dependent on form and size of the spring.

Operation cycle:
The springs are filled manual into the detangler. The rotation of the wheel in the detangler make an air cushion. This air cushion blows the dentangled springs on top into a container. There the springs can be taken away.
For an optimal dentangling of the different springs the rotation speed of the detangler wheel can be varied with a speed regulator.

Possibilities of use:
FEW 1, Springs with diameter 2 mm - 7 mm, free length max 35 mm.
FEW 2, Springs with diameter 5 mm - 12 mm, free length max 35 mm.

With the integrated detangler springs which were up to now impossible to process automatically can be feed in spring grinders, scragg and testing machines or automatic mounting stations in a production line.
With this spring detangler and feeder you have the possibility to change over to a different spring-type without changing parts. You have only to adjust the tangle sensor and the separator that it fits for the required diameter of spring.
It can be used with cylindrical, conical and barrel shape compression springs. To handle other shapes or dimensions of parts please contact us. Possibly simple changes of the system can enable the detangling of these parts as well.

Description od function:
The springs are filled into the vibrator feeder bowl manual or over a storage bunker. The vibration moves the springs over the feeding spirals to an adjustable chicane at the top of the bowl which presorts the springs. Afterwards the springs pass a sensor which detects tangled springs. Tangled springs are rejected by an airblast and fall back into the bowl where they are detangled and supplied again over the spirals to the sensor. Detangled springs leave the detangler and can be filled in a tube or can be transported over linear conveyors to the following machine.
