For the purpose of multiple machine assignment, continuation of production during breaks as well as for unmanned production, for years Hüller Hille offers optimized modules with its flexible production cells and systems.
- Multi-pallet storage system (MPS)
- Flexible pallet container (FPC)
- Multi-level pallet storage system
- Robot and gantry loader automation
An indispensable requirement for trouble-free, unmanned production are the following field-tested monitoring systems:
- Maintime-parallel drill breakage supervision
- Feed force and torque monitoring
- Tool time monitoring
- Workpiece measuring
- Flexible tool management and tool handling
- CNC tool management with automatic twin tool strategy
- Machine status display via mobile
- Video surveillance
The standard (NBH 95) version of the multi-pallet storage system (MPS) has been designed for 7 pallets in the system (NBH 170: 8 pallets). A manipulator arranged in the center of the system just moves one pallet only. This means:
- Low masses
- Low wear
- High reliability
The rotating loading and set-up station (standard) allows in-process loading and unloading. The set-up station can also be supplied as tiltable version (option) for large and badly accessible clamping fixtures. Extremely compact and space saving is the solution with two levels accepting 12 pallets in the system (NBH 170: 14 pallets).
Flexible pallet container
The flexible pallet container is the ideal, reasonably priced alternative if the space conditions do not allow the installation of a pool.
- Container in welded construction with openings for container loading station and NBH interface
- Rack (multi-level pallet storage system) in all welded steel construction (2 levels) with coolant drip pans below the pallet deposit places
- Welded machine/rack operating device in rigid frame structure
- Loading equipment with parallelogram mechanism moving in direction rack and machine interface
- Container loading station with manual rotary pallet table
- For pallet size 500 x 630 mm, 10 storage places at 2 levels
- Can be extended by max. 2 basic containers resp. mini containers
In case of an even larger parts spectrum or application of several Hüller Hille centers as flexible production system, multi-level pallet storage systems will be used. Thanks to efficient space utilization the capacity of the storage system will only be limited through the infrastructure of the hall.
The advantages at a glance:
- Compact, modular design
- Longer, unmanned production due to large storage capacity at minimal floor space
- Extensible from one production cell to flexible manufacturing system
- No additional linking facilities for FMS, transport to other machining stations through rack feeders
- Fast installation and commissioning
Flexible production system for machining of cylinder heads. Direct loading of clamping fixture in set-up station of NBH 95 machining center with robot automation (see photos at right).
Flexible production system for machining of different truck gear cases. Direct loading of clamping fixture from top with gantry loader automation. The gantry loader automation with several carriages can cover four NBH 145 machining centers.
