Gantry storage beams

Typical applications

These magnetic beams provide a solution for baking tray storage systems, in automated bakeries. The system picks multiple trays from storage and deposits them onto the production line. Once the production of a particular bread type has finished, the trays are returned into storage and the next tray type is brought out with no changes to the magnetic picking head. Coverage / length ofbeam: 8 metres.

The beam
Manufactured from a 100mm x 100mm x 6mm mild steel box section. All service pipe work is fully enclosed along one side of the beam. An identical enclosure along the other side houses the signal wiring, both services terminate in their own central connection point.


Magnetic heads
High-energy magnets retain their magnetism indefinitely, the magnet arrangement is determined taking into account, all tray types to be moved. The magnetic face is supplied with a stainless steel contact / wear plate. Rigidity and long life is guaranteed by the use of high quality components.


Air pressure required: 5 bar min, 10 bar max.


Compliance assemblies
Vertical compliance assemblies integrated into the beam to ensure that the magnets are correctly seated on the trays and provide up to 100mm of vertical movement.


Over travel sensors
Crash protection is provided on each vertical compliance assembly.


Part present sensors
Each magnet has part-present sensing.

Product case study

Problem


Products to be moved are baking trays, the sizes of which vary dependent upon bread type and size. The trays can be handled as individual trays, single strap and double strap. The contact area is limited to the roll edge at the top opening of each individual tray. Every tray type has a different pick up profile.

Solution
Eclipse Magnetics designed and manufactured single span, lightweight beams, supplied with the optimum number of pneumatically operated permanent magnetic heads to suit the required length of beam. The beams require compressed air for operation and electrical connections for sensing, and are supplied complete with all safety and positional feed back sensors for integration into any transfer gantry.
