Switchable magnet systems for stacking pieces of sheet metal
These magnet systems, comprising permanent magnets and a coil, are used
in particular for transporting suspended ferromagnetic items of sheet metal.
These systems can be used especially cost-effectively wherever there is
at least a 50% condition of „magnetically adhering“. This ensures
that the switch-on period of the coil is not greater than 50%. This condition
is always met for applications involving stacking systems. These systems
are optimized in respect of high levels of adhesive power, a mean deep action
and a low compensation current. These components effect an electrical time
constant on the part of the systems of approx. 50 ms to 120 ms. It is markedly
less than in the case of pure electromagnets. Given today’s usual
stacking speed, it is necessary to provide the magnet systems with control
electronics which allow a switching frequency of up to 200 switches per
minute and more. Such a high switching frequency can, however, only be realized
if the falling sheet metal is subjected to an additional force so that the
depositing process is accelerated such as is the case with destacking systems.
