solutions for heavy and damage-sensitive workpieces

 

 

NSM now offers two different concepts for taking metallic workpieces out of containers

for bulk materials, such as steel boxes or lattice boxes:

 

The conventional portal unloader, which can be utilised for workpieces weighing up to approx. 2 kg each,

and the new belt unloader, which has been specially developed for gentle workpiece handling

with high emptying performance.

 

 

Both systems are designed to be extremely space saving and by virtue of their independent

control function, they are also suitable for retrofitting in existing machines.

 

 

 

 

The bulk container is positioned with the help of a manual lifting trolley or

stacker on the floor under the magnetic unloader. The magnet dips into

the box at six defined positions. The contact of the magnet with the

workpiece is detected by a sensor. The magnet is switched on and raised

by the lifting mechanism to the required transfer height. The trolley moves

the magnet together with the attached cluster of workpieces and takes

them to the customer's handover position and released by switching off

the magnet.

 

 

 

The bulk container is placed by the operator into the take-up frame of a tilting

device. After confirmation, an angular magnetic conveyor belt then dips into

the box. Via the magnetic deflection roller on the conveyor head, the workpieces

are attracted and pulled off vertically upwards by the circulating belt by means

of integrated permanently magnetic adhesion strips. With progressive emptying

of the box, the tilting device assists the clustering of the bulk material and

makes possible, in combination with the automatically self-adapting conveyor

orientation, a system performance which is as homogeneous as possible

throughout the entire process.

After redirection onto the horizontal conveyor segment, the workpieces lie

chaotically distributed on the belt and are fed to the next process. With the

integrated demagnetising coil, undesired magnetising effects can be

neutralised in many cases already before passing the workpieces to the

subsequent processing line.
