Project Brief

End-of-Line Packaging Systems: Case Packers, Master Baggers & Palletizers

Automate case erection, drop/robotic case loading, woven-PP/PE master bagging, cobot/robotic palletizing, and rotary stretch wrapping.

Turning Loose Primary Packs Into Warehouse-Ready Unit Loads

End-of-line packaging is typically the last manual island in food, chemical, and consumer-goods plants—often tying up 4 to 8 operators per shift erecting RSC boxes, hand-packing pouches, taping flaps, and lifting 12–25 kg cartons onto wooden pallets. Within our packaging line systems architecture, end-of-line modules replace repetitive manual lifting with synchronized case packers, secondary master balers, robotic palletizers, and automatic pallet wrappers.

Depending on shipping distribution channels, primary packs either load into corrugated RSC/shelf-ready trays or group inside heavy-duty 140–180 μm PE / woven-PP secondary master bags.

Every downstream station is sized with progressive speed headroom so minor tape or blank reloads never halt primary filling.

End-of-Line Equipment Architecture Comparison

Compare shipping containment and palletizing modules by speed and payload:

End-of-Line Module Throughput Range Container / Payload Spec Floor Footprint Advantage
RSC Case Erector + Loader + Sealer 8–25 cases/min Corrugated RSC / HSC / SRP trays Inline linear or compact monoblock
Secondary PE / Woven-PP Master Bagger 6–18 master bales/min 650–900 × 350–450 mm (140–180 μm PE) Cuts corrugated board spend 50–65%
WP30 Cobot Carton Palletizer Up to 8–12 cartons/min Dual pallet bays; fenceless scanner option Fits 2.5 × 3.2 m tight retrofit aisles
4-Axis Articulated Robotic Palletizer 15–35+ cartons or bags/min Multi-pick vacuum/fork + slip-sheet Services 2–3 lines simultaneously

Flexible pouches require flatteners and orientation control before case loading, whereas rigid bottles use lane dividers.

System Integration Engineering Notes

  • Tape vs Nordson-Class Hot-Melt Case Sealing: Hot-melt EVA/metallocene glue seals faster above 15 cases/min and adds structural stacking rigidity in humid cold-storage warehouses.
  • Automatic Empty-Pallet Dispenser + Slip-Sheet: Pair high-speed robotic cells with a 15-pallet magazine dispenser and rotary arm stretch wrapper for 2+ hours of forklift-free autonomy.
  • GS1-128 Print-and-Apply Pallet/Case Labeling: Dual-panel corner-wrap applicators verify SSCC-18 pallet barcodes before warehouse WMS scan-in.

Scope Your End-of-Line Automation Cell

Provide case/bale dimensions (L × W × H), gross weight, cases/minute, and pallet Ti × Hi pattern via Project Brief.

V-curve over-speed cascade ratios from 100% process feed to 130% end-of-line palletizing
Designing secondary case packers at 120–125% of primary output allows buffer conveyors to drain automatically after micro-stops.
