Vertical Packaging Machine: 5 Critical Installation Mistakes Even Senior Electricians Make — Do Not Unpack Immediately Upon Delivery

New‑equipment arrival does not mean you can simply unbox, power‑on and run. Wrong installation location doubles future failure rates.

When a new vertical packaging machine arrives at your facility, the workshop team is eager to get production started. Forklifts unload crates, wooden cases get opened, and technicians rush to connect power and perform trial runs — many hope to have the machine operational within half an hour.

However, improper site selection for installation will significantly increase long‑term breakdown frequency. Chapter 3 of the equipment manual covers installation specifications and clearly lists five installation prohibitions. Below is a detailed breakdown.

Machine Installation Site Checklist

Mistake 1: Installing on a Non‑Level Surface

Manual specification excerpt:

For machine installation, take the top mating surface of the rear end‑sealing knife‑holder bracket as the reference plane. Place a spirit level on this reference surface. Adjust the four bottom levelling screws of the machine until the reference plane sits perfectly horizontal. Ensure the casters are lifted off the ground with clearance.

Why use this exact reference surface? The flatness of the end‑sealing knife holder directly defines sealing quality. If this reference plane is out‑of‑level, front and rear knife holders will not close in perfect parallel alignment during sealing. One side compresses firmly while the other side applies insufficient pressure, resulting in partially sealed, leak‑prone finished bags.

Casters must be off the floor. Many operators leave casters resting on ground for convenience. Since casters swivel freely, operating vibration generates tiny positional shifts, and horizontal alignment drifts within days. Best practice: levelling screws support the full machine weight; casters hang suspended without ground contact.

Level‑check frequency: Perform full levelling at initial installation; re‑inspect after one month of runtime; conduct quarterly checks thereafter.

Mistake 2: Placing Machine Under Direct Sunlight

Manual specification excerpt:

Installing the machine in locations with direct sunlight or intense ambient light will cause photo‑eye malfunction.

Why strong light damages photo‑eyes Color‑mark photo‑eyes work by emitting light onto packaging film and measuring reflected light intensity. Dark color‑marks absorb light and return weak reflection; light‑colored base film reflects strongly. The sensor detects differences in reflected light to locate color‑mark positions.

What happens under direct sunlight? Intense natural sunlight strikes film surfaces and photo‑eye receivers, similar to scanning a QR‑code outdoors under bright sunshine with heavy screen glare. Strong background ambient light overwhelms signal differences between color‑marks and base film. The photo‑eye becomes “blind”, triggering constant error alarms or completely wrong bag‑cut positions.

Do not position the machine beside windows or under skylights where strong light falls onto equipment. If relocation is impossible within workshop layout constraints, fit a light‑shield cover over the photo‑eye assembly.

Mistake 3: Extreme Operating Temperatures or Over‑confined Space

Official technical specifications from equipment manual:

Issues caused by out‑of‑range temperature:

• Below 0 °C: Lubricating oil thickens, cylinder response slows down, heating efficiency of temperature controllers drops.
• Above 45 °C: Electrical components age rapidly, solid‑state relays suffer poor heat dissipation, temperature‑control precision degrades.

Problems caused by insufficient space: ‑ Operators cannot stand in the correct ergonomic working position ‑ Safety guards cannot be fully opened for cleaning and maintenance ‑ Limited clearance for film‑roll replacement

Recommended operator working position: Stand directly in front of HMI control panel, 30‑50 cm away. Eyes level with temperature‑display screens. This position allows simultaneous observation of control panel, forming former and end‑sealing zones.

Mistake 4: Installation Close to Vibration Sources

Manual specification excerpt: Do not install the machine in areas with strong vibration sources.

Common vibration sources inside workshops: punch presses, large air compressors, crushers, heavy‑duty industrial fans. Their operating vibration transmits through concrete floors to the packaging machine.

Negative impacts of vibration: ‑ Degraded dosing accuracy (weight‑based measuring units show unstable readings under vibration) ‑ Unstable film‑pull length; swing‑arm mechanisms disturbed by ground vibration ‑ Seam misalignment as knife‑holders shift during the sealing cycle

Keep minimum distance of 3 meters from vibration‑generating machinery. If relocation is impractical, install anti‑vibration damping pads under machine base.

Mistake 5: Installation Near Ventilation Outlets or Corrosive / Dusty Atmosphere

Manual specification excerpt: Avoid installation near air‑conditioning / ventilation outlets, or environments filled with corrosive gas or heavy dust.

Dangers of direct airflow from ventilation outlets: Cold air blowing continuously onto sealing zones creates unstable thermal conditions. Even if temperature controller shows target set‑point, actual sealing‑surface temperature drops due to airflow, leading to weak, unreliable bag seals.

Dangers of corrosive gas and heavy dust: ‑ Corrosive fumes (for example vapours from acidic workshop cleaning agents) corrode metal component pins and printed‑circuit‑board copper traces. ‑ Dust accumulates inside electrical cabinets covering circuit boards and heat sinks, causing overheating and creepage‑current risks.
