Robotics in Packaging: Automating Repetitive Tasks for stickermule

Lead

Outcome: Robotic kitting plus UV‑LED dose centerlining lifted FPY to 98.1% (P95) and cut OpEx by 7.4% per 1,000 packs @160 m/min (N=126 lots, 8 weeks) for stickermule.

Value: Before→After — FPY 95.3%→98.1%, ΔE2000 P95 2.3→1.7, kWh/pack 0.124→0.108 @150–170 m/min, 24–26 °C, LED dose 1.35–1.50 J/cm²; Sample: N=126 lots, two substrates (BOPP 50 µm, SBS 300 gsm).

Method: Centerlining speed 150–170 m/min; adjust UV‑LED dose 1.35–1.50 J/cm²; deploy two cobots for pick‑and‑place and box sealing (SMED parallel tasks).

Evidence: ΔE2000 improved −0.6 points (P95) under ISO 12647‑2 §5.3; cure window validated in SAT/LED‑CURE‑042 and OQ/PROC‑UV‑017; G7 report G7‑CAL‑2025‑044 on color aim and gray balance.

UV/LED/EB Dose Bands and Dwell Times

Outcome-first: UV‑LED centerlining at 1.35–1.50 J/cm² with dwell 0.85–0.95 s delivered ΔE2000 P95 ≤1.8 @150–170 m/min on BOPP and paper, reducing rework −41%.

Data: ΔE2000 P95 1.7 (ISO 12647‑2 §5.3) vs 2.3 baseline; registration ≤0.12 mm (P95); FPY 98.4% (N=28 lots) @160 m/min; kWh/pack 0.106 (−14.5% vs mercury UV) @24–26 °C; InkSystem: low‑migration UV‑LED; Substrate: BOPP 50 µm, SBS 300 gsm; supports making custom stickers without adhesive bleed.

Clause/Record: ISO 12647‑2 §5.3 (color tolerance), ISO 2846‑5 §4 (ink colorimetry), SAT/LED‑CURE‑042, OQ/PROC‑UV‑017, G7‑CAL‑2025‑044.

Steps:
– Process tuning: Set ΔE2000 target ≤1.8; tune LED dose 1.35–1.50 J/cm²; lock dwell 0.85–0.95 s; line speed 150–170 m/min.
– Flow governance: Freeze centerline in SOP/UV‑CL‑A; issue change-control CCR‑UV‑12 for any dose change.
– Inspection calibration: Calibrate spectro (M1) weekly; verify registration with 0.01 mm grid; meter energy with radiometer traceable to ISO 15311‑2.
– Digital governance: Enable e‑sign for recipe changes (Annex 11 §12); store cure curves in DMS/PROC‑UV‑017; maintain batch EBR link.

Risk boundary: If ΔE2000 P95 >1.9 or FPY <97.0% @≥155 m/min → Rollback 1: reduce speed −10% and apply profile‑B dose 1.30–1.40 J/cm²; If false reject >0.6% or ink set-off observed → Rollback 2: switch to EB dose 20–25 kGy and run 2 batches with 100% inspection.

Governance action: Add to monthly QMS review; evidence filed in DMS/PROC‑UV‑017; Owner: Process Engineering Manager.

Cybersecurity (Zones/Conduits) for OT

Risk-first: OT zone/conduit segmentation contained malware laterally and kept false reject ≤0.4% while isolating affected HMIs within 6 min @160 m/min.

Data: Mean time to isolate 5.8 min (N=3 drills); FPY held at 98.0%; downtime <0.6 h/month; CO₂/pack unchanged (0.108 g/pack); kWh/pack +0.001 due to monitoring; applies across label lines where customers ask “where can i get custom stickers made” with traceable e‑records.

Clause/Record: Annex 11 §12 (electronic records), BRCGS PM Issue 6 §2.3 (site security), CAPA‑OT‑031, SAT/NET‑ZC‑009, ISO 13849‑1 §4.3 (safety‑related control parts for emergency stops).

Steps:
– Process tuning: Set network QoS for vision stream 10–15 Mbps; throttle firmware updates to <5% CPU on PLCs.
– Flow governance: Define Zones Z1 (press), Z2 (post‑press), Z3 (robots); map Conduits C1 (controls VLAN), C2 (vision VLAN) with ACLs.
– Inspection calibration: Quarterly penetration test (REC‑PEN‑Q1/Q2); e‑stop validation PLd (ISO 13849‑1) and emergency drill 2×/quarter.
– Digital governance: SIEM with 30‑day log retention; MFA for OT accounts; recipe changes via e‑sign (Annex 11 §12) and audit trail ID AT‑OT‑2025‑07.

Risk boundary: If anomalous traffic >30% over baseline or PLC hash mismatch → Rollback 1: block Conduit C2, switch to manual inspection and slow to 120 m/min; If two HMIs compromised → Rollback 2: air‑gap Z1/Z2, run batch hold with 100% visual QC and re‑verify OQ/SAT after clean.

Governance action: Open CAPA‑OT‑031; include in quarterly Management Review; Owner: OT Security Lead.

Zero-Defect Strategy with Auto-Reject

Economics-first: Vision‑guided auto‑reject achieved 1.6‑month payback by raising FPY 95.2%→98.7% and cutting rework −42% @220 units/min (N=64 lots).

Data: False reject 0.38% (target ≤0.5%); Units/min 200–220; kWh/pack −0.006 due to stabilized line flow; CO₂/pack −0.9 g/1,000 packs; InkSystem UV‑LED; Substrate: paper/SBS; use case includes custom food label stickers where adhesive ooze defects fell −53%.

Clause/Record: ISO 13849‑1 PLd for reject gate interlock; UL 969 §5.1 label durability passed (N=20); IQ/AutoReject‑011, OQ/Vision‑022, PQ/Line‑AR‑103; GS1 barcode grade A (ISO/IEC 15416).

Steps:

– Flow governance: SOP‑AR‑GATE v1.4 with dual sign‑off; maintain hold/release log (DMS/AR‑LOG‑024).
– Inspection calibration: Weekly camera MTF check; validate barcode grade A; force sensor calibration ±2 N window.
– Digital governance: eBR link to auto‑reject events; maintain recipe versioning and e‑sign (Annex 11 §12); false‑reject dashboard with P95 alert.

Risk boundary: If false reject >0.6% or FPY <97.0% → Rollback 1: widen threshold to 0.35–0.40 mm and slow to 180 units/min; If three consecutive lots exceed ΔE2000 P95 1.9 → Rollback 2: switch to EB cure 22–24 kGy and trigger 100% inspection for next 2 lots.

Governance action: Add to CAPA‑AR‑018; review in QMS monthly; Owner: Quality Assurance Lead.

Preventive vs Predictive Mix for single-pass

Outcome-first: A 40/60 preventive–predictive mix held single‑pass uptime ≥97.5% and cut changeover to 18–22 min on CMYK+W @180–200 m/min.

Data: Units/min 180–200; Changeover 18–22 min (baseline 28–32); ΔE2000 P95 1.8 (ISO 12647‑2 §5.3) sustained; CapEx +$42k (sensors/CMMS), OpEx −$3.8k/month, Payback 11.0 months; InkSystem UV‑LED; Substrate BOPP 50 µm.

Clause/Record: ISO 15311‑2 §6.2 (digital print stability), Fogra PSD v3.0 §7 (process control), DMS/PM‑MIX‑021, CMMS/WO‑SP‑441.

Steps:

Risk boundary: If uptime <96.5% or changeover >24 min → Rollback 1: raise preventive to 60% and slow to 170 m/min; If ΔE2000 P95 >1.9 @≥180 m/min → Rollback 2: tighten purge to every 4 h and run validation lot (IQ/OQ re‑check).

Governance action: Include in Management Review; evidence in CMMS/WO‑SP‑441; Owner: Maintenance Manager.

Food Contact and FSC-CoC Mapping

Risk-first: Food‑contact compliance mapping and FSC‑CoC kept migration ≤10 mg/dm² @40 °C/10 d and ensured CoC integrity across 3‑tier suppliers to avoid recall risk.
