Shrnutí

An online labeling, sealing, and shrinking machine applies identification labels, forms a continuous film package, seals the enclosure, and shrinks the film uniformly—fully integrated into the continuous conveyor line without manual intervention. Designed for rolls of nonwovens, paper, textiles, boxes, and bulk packs, this automated configuration provides a pristine, moisture-resistant, and dust-tight wrap. Our engineered solution pairs an industrial automatic labeler with a high-speed motion sealer and a dual-zone hot-air shrink tunnel. This technical guide outlines the inline station progression, geometric capacity check calculations, and per-pack film consumption formulas to streamline your packaging line integration.

Automated converting and packaging lines transport hollow-core nonwoven or paper rolls on motorized roller beds directly through an integrated packaging cell. Pneumatic alignment guides and centering pushers square each cylindrical core along the centerline, feeding it through an unwinding cradle loaded with center-folded polyolefin (POF) or polyethylene (PE) film. Synchronized horizontal motion cutters seal and separate each wrapped unit without stopping the conveyor. The wrapped roll enters a digitally modulated hot-air shrink tunnel that activates bi-axially oriented film tension, enclosed by perimeter safety guarding with LOTO-compliant interlocks. Every finished roll emerges structurally rigid, dust-sealed, and barcoded for inventory management.

Proč označovat a zmenšovat v řadě

Offline labeling and wrapping create an engineering bottleneck: they demand manual palletizing, buffer staging, and secondary manual feeding into standalone shrink wrappers. This multi-touch workflow escalates labor overhead and introduces scuffing, edge curling, and core contamination.

By integrating labeling, sealing, and thermal shrinking directly into the converting or slitting outfeed:

  • Zero Buffer Staging: Each product is labeled and sealed immediately as it exits the core-winding or converting station, eliminating WIP (work-in-progress) floor clutter.
  • Data Integrity & Traceability: PLC-tracked print-and-apply applicators sync directly with your MES/ERP, guaranteeing that variable barcodes, lot numbers, and net weights correspond to the active roll.
  • Immediate Barrier Protection: Instant encapsulation protects delicate nonwovens, medical rolls, fine paper, or optical films from environmental moisture, particulate dust, and handling damage right from the first minute of production.

Stanice v pořadí

[Infeed & Centering] → [Precision Labeling] → [Continuous Motion Sealing] → [Dual-Air Shrink Tunnel] → [Cooling & Outfeed]
  1. Přísun a umístění: Pneumatic centering guides and motorized side-belts square the incoming roll or carton along the conveyor centerline, eliminating skew before entering the film envelope.
  2. Značení: An industrial wipe-on or tamp-blow label applicator applies high-density 1D/2D barcodes or branding labels at a fixed datum point on the package perimeter or face.
  3. Těsnění: A continuous-motion horizontal sealer uses center-folded film. A mechanical pin-wheel micro-perforates the film for air venting, while a servo-driven cross-seal carriage tracks product motion, cutting and impulse-welding the film with zero conveyor stop.
  4. Zmenšování: The loosely bagged package enters a circulating hot-air convection tunnel. Controlled thermal cross-flow triggers biaxial shrink forces (up to 50%–60% shrinkage in POF), pulling the skin-tight membrane across the contours and over the roll core rims.
  5. Chlazení a výstup: Ambient air blowers or high-velocity cooling fans rapidly set the polymer weld and tension the film skin, ensuring dimensional stability before robotic transfer or case packing.

Film advance length is monitored by an integrated optical photocell and rotary encoder loop, ensuring uniform film cut-off and consistent tail lengths across varying line speeds.

The decision to apply the label directly onto the product substrate prior to wrapping or on the exterior shrink film depends on downstream scanning distances and physical exposure.

Pozice štítku Inženýrské výhody Operational Caveats & Mitigations
Pod filmem (Pre-wrap application) Absolute tamper resistance; 100% protection against surface abrasion, moisture, grease, and industrial dust during transit. Film optical glare can impede wide-angle barcode reading; requires high-clarity POF film and matte thermal labels.
Přes film (Post-shrink application) Zero optical glare; crisp 1D/2D scanner readability for high-speed logistics routing; labels can be modified at the palletizer. Label adhesive must bond reliably to PE/POF shrink film; labeler must be stationed po the cooling conveyor to prevent heat curling.

For consumer retail rolls and sterile nonwovens, applying under the film preserves pristine label typography. For dynamic high-bay distribution warehouses utilizing fixed overhead vision cameras, labeling over the film eliminates specular reflection risks.

Technical parameters for standard industrial continuous-motion sealers and paired shrink tunnels:

Technické parametry MO-350 MO-600
Max. Sealing Width až do 350 mm až do 600 mm
Max. Sealing Height až do 200 mm až do 250 mm
Max. Film Roll Specs 580 mm web width × 280 mm OD 860 mm web width × 280 mm OD
Připojená energie 10.5 kW 12.5 kW
Pneumatické napájení 0.5–0.6 MPa (Clean, dry air) 0.5–0.6 MPa (Clean, dry air)
Vlastní hmotnost stroje Cca. 600 kg Cca. 900 kg

Both platforms operate on standard 380 V, 50–60 Hz, 3-phase industrial power with an adjustable operational pass-line height of 780–820 mm to match upstream lines. Compatible consumables include center-folded Polyolefin (POF, 12–25 µm) and low-density Polyethylene (LDPE, 25–50 µm). The internal tunnel conveyor utilizes heavy-duty transport chains fitted with freely rotating, silicone-sleeved steel rods to eliminate hot-spot marks on the bottom film.

Geometric envelope rule for the MO-350: Product Width + Product Height must not exceed 400 mm. Specific labeler dispensing speeds, thermal heating power, and line belt speeds are calibrated to target cycle outputs during project quoting.

To verify machine envelope compatibility, evaluate three critical geometric parameters:

  1. Šířka výrobku versus rated Sealing Bar Width
  2. Výška výrobku versus rated Clearance Throat Opening
  3. Cross-Sectional Enveloping Perimeter Check: Product Width + Product Height ≤ Machine Envelope Limit

Příklad technického výpočtu:

Consider a hollow nonwoven roll with an Outer Diameter (Width) of 250 mm and a Face Length (Height) of 150 mm, conveyed flat in an eye-to-sky orientation:

Hodnotící kritérium Hodnota produktu MO-350 Operational Limit Inženýrské posouzení
Cross-Conveyor Width 250 mm 350 mm Přejít (100 mm lateral clearance)
Vertical Clearance Height 150 mm 200 mm Přejít (50 mm vertical head room)
Cross-Sectional Sum 250 + 150 = 400 mm 400 mm Marginal Limit (Zero engineering tolerance)

Verdikt inženýrství: While mathematically acceptable, operating at the exact limit of 400 mm eliminates lateral tracking tolerances and risks film web snagging during high-speed cross-sealing. For continuous high-throughput roll conversion lines, sizing up to the MO-600 platform is recommended to maintain a reliable 20–30 mm operating margin.

Accurate film budgeting prevents web blowout and minimizes trim scrap. Calculate your center-folded film requirements using the following standard packaging equations:

  • Required Center-Folded Film Width: Film Width ≈ Product Width + Product Height + Safety Allowance
  • Linear Film Web Cut-Off Length Per Unit: Film Length ≈ Product Length + Product Height + Sealing Allowance

Using our standard test cylinder (Diameter/Width = 250 mm, Length = 250 mm, Axial Height = 150 mm) with a conservative 50 mm engineering allowance for corner tucks, weld margins, and shrink draw:

  • Film Roll Web Width: 250 mm + 150 mm + 50 mm = 450 mm (Well within the MO-350 maximum web width limit of 580 mm).
  • Linear Cut-Off Length per Cycle: 250 mm + 150 mm + 50 mm = 450 mm (0.45 m) per roll.

To determine annual film procurement volume: Total Mass (kg) = Total Annual Cycles × Cut-Off Length (m) × Film Width (m) × Film Density (g/cm³) × Thickness (µm) × 10⁻³

  3. Labeling Architecture: What are the label dimensions, barcode density, and orientation (perimeter face, end-disc, or core-adjacent)?
  4. Label Sequence: Does the application mandate label adhesion directly onto the product substrate (under the film) or over the finished shrink-wrapped package (over the film)?
  5. Specifikace filmu: Are you running high-clarity biaxial POF (15–19 µm) or puncture-resistant industrial LDPE (30–50 µm)?
  6. Následná integrace: Does the shrink tunnel feed directly into automatic cartoning, case packing, manual sorting, or a robotic palletizing cell?

Bezpečnost

The integrated labeling, sealing, and shrink packaging line complies with mandatory European and international equipment safety directives:

  • ČSN EN ISO 12100:2010: Risk assessment and risk reduction principles across all mechanical and pneumatic handling assemblies.
  • A 415-10: Specific safety standard governing packaging machines, forming systems, and horizontal wrapping machinery.
  • A 60204-1: Electrical safety, insulation testing, and control circuit grounding.

Hazard Zones and Risk Controls:

  • Hot-Knife Transverse Sealer: Heated impulse and continuous hot-wire cutting blades reach temperatures exceeding 180 °C – 220 °C. The sealing head is fully shielded by interlocked acrylic and steel enclosures, fitted with dual-channel category-4 interlock switches.
  • Thermal Shrink Oven: Internal heating coils maintain operating air temperatures between 140 °C and 180 °C. Perimeter heat-shielded access panels, visual temperature warnings, and automatic tunnel cool-down safety delays prevent conveyor belt burning during planned or sudden line stops.

Často kladené otázky k inženýrství

Q: Can this machine package and shrink-wrap rolls that have an open center core? A: Yes. The center-folded film wraps the outer circumference, and during cross-sealing and tunnel transit, the balanced shrink draw pulls the film symmetrically over the roll shoulders, creating clean, reinforced end rings while leaving the center core accessible for shaft handling.

Q: How does the system handle trapped air during high-speed thermal shrinking? A: Prior to entering the sealing bar, the film passes over an integrated adjustable needle-wheel micro-perforator. This mechanism introduces micro-pores that release trapped air as the film contracts in the oven, eliminating ballooning while preserving full dust resistance.

Q: Which film polymer formulation delivers the best structural results? A: Center-folded cross-linked Polyolefin (POF, 15–25 µm) is ideal for light-to-medium rolls and retail display packs due to its exceptional clarity and high tensile puncture resistance. For heavy industrial rolls or long transit routes, low-density Polyethylene (LDPE, 35–60 µm) is preferred for superior tear strength.

Q: Can the automated labeler be relocated downstream of the shrink tunnel? A: Yes. For logistics-heavy applications where barcodes must be read without film interference, the labeler can be mounted over the outfeed conveyor immediately following the fan-forced cooling zone, once the film surface temperature drops below 35 °C.
