Finding solutions to efficiently lift, drop, and roll products through your press line is a fundamental part of SparTek’s strategy to improve the efficiency and profitability of your manufacturing process.
Direct vs. Staged Loading/Unloading
Direct Method – Smaller Footprint
- Direct Loader (assisted or automatic) indexes down the infeed side of the open press loading each opening.
- Unloaders automatically "follow" the direct loader receiving the pressed panel as each opening is loaded.
- Press closes to begin pressing cycle, next stack shuttles from pre-press to loader.
- Press opens at end of cycle.
- Once the press is empty the unloader moves the pressed stack down and shuttles the panels to trim saw.
- Process repeats.
Direct vs. Staged Loading/Unloading
Staged Method – More Press Cycles Per Hour
- Press closes to “bake” current load of panels.
- Charger feeder moves to the top of the charger and travels downward loading each charger opening, receives and holds the next stack from the pre-press.
- Rack unloader simultaneously begins unloading the receiving rack from the top down.
- When charger is full, charger feeder receives next stack from pre-press
- When the receiving rack is empty, unloader moves down and shuttles pressed panels to the trim saw.
- Press completes cycle and opens.
- All openings on the press are simultaneously loaded by the charger and pressed panels are simultaneously unloaded from the press.
- Process repeats.
