Automatic Bag Placer – The Industry Standard for Reliable Bag Placing

Welcome to the next generation of packaging automation. Our Automatic Bag Placer (also known as the Automatic Bag Placing and Packaging Machine.mp4) is designed to automatically pick, open, and place empty bags onto filling spouts or packaging machine outlets. Whether you pack dry mortar, chemicals, animal feed, or food products, this machine eliminates manual bag handling – boosting speed, consistency, and safety.

If you are still placing bags by hand, you are losing money every shift. Read on to discover why hundreds of factories have switched to our Automatic Bag Placing and Packaging Machine.


What Is an Automatic Bag Placer?

An Automatic Bag Placer is an electro-pneumatic or servo-driven machine that performs three tasks automatically:

  1. Pick – A vacuum cup system picks one bag from a stack magazine

  2. Open – The bag mouth is opened by suction cups or mechanical fingers

  3. Place – The opened bag is placed onto a filling spout, discharge chute, or packaging machine outlet

When integrated with a filling scale, bag sealer, and conveyor, the same equipment becomes a complete Automatic Bag Placing and Packaging Machine – a fully automated solution from empty bag to sealed, finished package.

Key Features of Our Automatic Bag Placing and Packaging Machine

Every Automatic Bag Placer we ship includes the following standard features:

1. Heavy-Duty Industrial Construction

Built for 24/7 operation in dusty, harsh environments (cement, dry mortar, chemicals). Stainless steel contact surfaces and sealed bearings ensure long life.

2. User-Friendly Touchscreen HMI

The 7-inch color screen stores up to 50 bag recipes. Changeover between different bag sizes takes under 5 minutes – no tools required for most adjustments.

3. Automatic Bag Magazine

Holds 150–300 bags (depending on thickness). Low-bag sensor triggers an alert or automatically switches to a secondary magazine for continuous operation.

4. Vacuum Cup Pick-and-Place System

Gentle on bags but extremely reliable. Double-cup design handles misaligned or slightly wrinkled bags without dropping.

5. Bag Mouth Opening Verification

A photoelectric sensor confirms the bag mouth is fully open before the placement cycle begins. This prevents misfeeds and product spillage.

6. Spout Compatibility

Works with round, square, or tapered filling spouts. Optional silicone ring adapter for dusty products (reduces dust escape during placement).

7. Safety Features

  • Full enclosure with interlocked doors

  • Emergency stop buttons on both sides

  • Overload protection on all servos

  • CE, UL, or CSA certification available


Why Upgrade to an Automatic Bag Placer?

Companies that replace manual bag placing with our Automatic Bag Placing and Packaging Machine typically see:

MetricBefore (Manual)After (Automatic)Improvement

“Our old line needed three people just to place bags. Now the automatic bag placer does it perfectly every time. We paid for the machine in 9 months.”
— Production Manager, dry mortar plant, Germany


Bag Types Our Automatic Bag Placing and Packaging Machine Can Handle

One machine – multiple bag styles. Our Automatic Bag Placer adapts to:

  • Valve bags (paper or plastic) – The bag is placed onto a valve spout; the product flows through the valve opening.

  • Open-mouth bags – The bag mouth is held open while the product drops or is blown in.

  • Pinch-bottom bags – Bags with pre-applied adhesive that is activated by heat after filling.

  • Gusseted bags – Side gussets are opened fully before placement.

Simply change the bag grippers and adjust the magazine – no mechanical modifications needed for most size changes.


 Industries That Benefit Most

Our Automatic Bag Placing and Packaging Machine is used worldwide in:

IndustryTypical ProductBag Type
Dry mortar & constructionCement, plaster, grout, tile adhesiveValve bag, open-mouth
ChemicalsPowders, granules, flakesPinch-bottom, valve
FoodFlour, sugar, rice, pet foodOpen-mouth, gusseted
Feed & agricultureAnimal feed, seeds, fertilizerWoven PP, paper
MineralsSand, perlite, calcium carbonateHeavy-duty paper
Building materialsInsulation, perlite, gypsumValve bag

If your product is dry, free-flowing, or semi-free-flowing, an Automatic Bag Placer will work for your line.


 Optional Upgrades for Your Automatic Bag Placing and Packaging Machine

Customize your Automatic Bag Placer with these add-ons:

  • Automatic bag top trimmer – Cuts ragged bag tops before sealing

  • Integrated heat sealer – For pinch bags or polyethylene inner liners

  • Bag flattener / shaper – Creates uniform, pallet-ready bags

  • Inkjet or thermal transfer printer – Prints date, lot number, or barcode on each bag

  • Bag kicker / reject station – Automatically removes poorly placed bags

  • Second bag magazine – For continuous operation (zero downtime for reloading)

  • Dust extraction hood – Connects to plant dust collection system

  • Remote diagnostic module – Real-time support from our engineers

  • Bag presence sensor after filling – Confirms bag remains on spout during fill cycle


How the Automatic Bag Placing Cycle Works

Here is the step-by-step sequence of our Automatic Bag Placing and Packaging Machine:

  1. Magazine feed – Bags are stacked on an inclined or horizontal magazine

  2. Bag pick – Vacuum cups pick the front bag from the stack

  3. Bag transfer – The bag is moved to the opening station

  4. Bag mouth opening – Upper and lower suction cups pull the bag mouth open

  5. Opening verification – Sensor confirms the opening width is correct

  6. Spout insertion – Mechanical fingers or a pusher places the bag onto the filling spout

  7. Bag release – Grippers release the bag; it is now held by the spout only

  8. Fill cycle starts – Filling scale or auger discharges product into the bag

  9. Cycle repeats – While one bag is filling, the placer prepares the next bag

Total cycle time: 3–6 seconds depending on bag size and product.


Integration with Your Existing Line

Our Automatic Bag Placing and Packaging Machine is designed to be a drop-in replacement for manual bag placing stations. It connects to:

  • Upstream – Filling scale, net weigher, auger filler, or blow filler

  • Downstream – Belt conveyor, bag sealer (heat, sewing, or adhesive), bag flattener, palletizer

Standard communication protocols (Profinet, EtherNet/IP, Modbus TCP) ensure easy integration with your existing PLC or line controller. We also provide I/O wiring diagrams and ladder logic examples for popular brands (Siemens, Allen‑Bradley, Mitsubishi).

 Frequently Asked Questions (FAQ)

Q1: What is the difference between an Automatic Bag Placer and an Automatic Bag Placing and Packaging Machine?

A: An Automatic Bag Placer only places the bag onto the spout. An Automatic Bag Placing and Packaging Machine includes bag placement plus downstream functions like filling, sealing, and conveying – though in common usage, the terms are often used interchangeably.

Q2: Can your Automatic Bag Placer handle dirty or dusty bags?

A: Yes. We offer a dust extraction hood and reinforced vacuum cups for dusty environments (cement, carbon black, etc.).

Q3: How long does a bag size changeover take?

A: Typically 3–5 minutes. Adjust the magazine guides, change the suction cup positions, and select the new recipe on the HMI.

Q4: What is the power requirement?

A: 380V / 50Hz / 3-phase (208V, 400V, 415V, 460V available). Compressed air: 6 bar, 300 L/min.

Q5: Do you offer a trial or rental program?

A: Yes. We can ship a demo unit to your plant for a 30-day trial. Contact us for terms.

Q6: What is the typical payback period?

A: Most customers recover their investment in 6–12 months through labor savings and reduced waste.
