Automatický balicí stroj na EPS a sendvičové panely: Specifikace a nastavení

Shrnutí Our automatic panel wrapping machine spirals stretch film around EPS panels, sandwich panels and boards as they pass through a rotating ring on a conveyor. It handles packages 1000–1500 mm wide, 300–1400 mm high and 2000–3000 mm long at a 20 50–XNUMX XNUMX ot./min ring speed. It runs online with a panel line or offline. This guide covers the process, specifications, ring sizing, film setup and wrap time.

How we wrap an EPS or sandwich panel, step by step

We built the machine in this 217 s video for EPS and sandwich panels. Each step below adds the setting behind it:

  1. 0–48 s, přísuv. The panel enters on the motor-driven infeed conveyor under the press rollers, with side guides centring it on the ring axis. On our EPS machine a belt conveyor protects the panel face, and a sensor detects the panel before the wrap starts.
  2. 48–104 s, film start. Our operator draws the film tail from the roll and leads it over the panel front at the infeed, where the press rollers hold it in place.
  3. 104–200 s, spiral wrapping. The conveyor carries the panel through the turning ring. The ratio of ring speed to conveyor speed sets the overlap, adjustable from 20% to 90%; inverters drive both, so overlap is a setting on the HMI. Guide rollers hold the panel straight for its full length.
  4. 200–217 s, finished panel. The wrapped panel is stood upright, covered along its full length.

The panel never turns. Long, flat panels stay supported on the conveyor for the whole cycle, which protects edges and faces.

Our EPS packing machine is a separate, lighter machine for EPS panels, with its own size range:

EPS variant Hodnota
Velikost objektu W 1000–1250 mm, H 600–1200 mm, L over 2000 mm
Infeed / outfeed conveyor 2 000 mm každý, motoricky poháněný
Rychlost zvonění 20 60–XNUMX XNUMX ot./min
Výkon / hmotnost about 3.5 kW / about 1850 kg
film width 200–250 mm, OD 100–200 mm, ID 76 mm

The two machines have different length ranges: the panel machine is specified for 2000–3000 mm packages, the EPS machine for panels over 2000 mm. | Panel holding | two press-down devices and left/right side protection |

Ring sizing for panel stacks

The ring must clear the diagonal of the package cross-section plus the film carriage. Work it out like this:

  • Úhlopříčka = √(W² + H²). The largest standard package, 1500 × 1400 mm, has a 2052 mm diagonal.
  • Our design rule from a board-stack project: a W 1.2 × H 1.5 m stack, 1921 mm diagonal, needed a ring OD above 2300 mm. That figure is the ring outer diameter. We build each wrapper to order, so the same model can carry different parameters from one project to the next.
  • Výška stohu: stacking panels raises H quickly. Size the ring for the tallest stack you ship, not a single panel.

Stretch film setup for EPS and sandwich panels

The panel machine runs a standard film format:

Parametr filmu Panel machine
Typ filmu Stretch film / polyethylene
Tloušťka 20–40 µm
Šířka 300 – 500 mm
Vnější průměr válce 100 – 180 mm
ID jádra 76 mm

Pravidla výběru, která používáme:

  • EPS panels: soft faces dent under high tension. Run lower tension and film from the thin end of the 20–40 µm range, with more overlap rather than more force.
  • Sandwich panels with steel faces: sharp edges cut thin film. Use film from the thick end of the range and add edge protection before wrapping.
  • Film width: wider film cuts wrap time; narrower film follows short packages more closely.

Wrap time per panel package

Wrap time follows from film width, overlap and ring speed:

  1. Výška tónu na otáčku prstence = film width × (1 − overlap). 500 mm film at 50% overlap gives a 250 mm pitch.
  2. Otáčky prstence = package length ÷ pitch. A 3000 mm package needs 12 turns.
  3. Doba obalu = turns ÷ ring speed. At 20–50 r/min that is 36 s down to 14.4 s of spiral wrapping, before head and tail wraps.

On the EPS variant, 250 mm film at 50% overlap gives a 125 mm pitch. A 3000 mm panel needs 24 turns, which is 24 s at 60 r/min. Add head and tail wraps, the film cut and the infeed and discharge transfer for the full cycle.

Surface protection and panel holding

Light EPS panels move under film tension unless they are held. Our machines fix the package in three ways:

  • Press-down devices with soft contact material hold the stack from above, so the top face is not marked.
  • Side guides and supporting rollers keep the package centred and straight through the ring.
  • Belt conveyors on the EPS variant protect the product surface where rollers would mark it.

Line integration, installation and delivery

The machine works online behind a panel line or offline as a standalone station:

  • Ovládání: PLC and HMI with automatic programs, connectable to the production line. Manual and automatic modes for changeovers.
  • Conveyor height: we match the infeed height to your line at the connection point and fix it on the layout drawing.
  • Umístění: photo-sensors detect the package and set the wrapping position.
  • Bezpečnost: light beam, emergency stop, safety enclosures and warning signals. Alarms trigger automatically when a fault occurs.
  • Dodací lhůta: standard horizontal wrappers ship in about 45 days, customised machines in about 60 days.

ISO 12100 sets the risk-assessment method and EN 415-10 the general packaging machine requirements. Which standards apply depends on the destination market.

Často kladené otázky k inženýrství

Q: Which panel sizes does the machine take? A: Packages 1000–1500 mm wide, 300–1400 mm high and 2000–3000 mm long. Our EPS variant takes W 1000–1250 mm, H 600–1200 mm and lengths over 2000 mm.

Q: How long does one panel package take to wrap? A: A 3000 mm package with 500 mm film at 50% overlap needs 12 ring turns. That is 14.4–36 s at 20–50 r/min, plus transfer time.

Q: How do I stop EPS panels from being crushed? A: Lower the film tension and use film from the thin end of the 20–40 µm range, with more overlap. Hold the stack with soft press-down devices instead of film force.

Q: What ring size do I need for stacked panels? A: Take the cross-section diagonal √(W² + H²) and add carriage clearance. On a W 1.2 × H 1.5 m stack, our ring OD was above 2300 mm.

Q: Can the wrapper connect to our panel production line? A: Yes. PLC and HMI control connects to the line, and we match the infeed conveyor to your line height on the layout drawing. Standard machines ship in about 45 days.
