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.
An Automatic Bag Placer is an electro-pneumatic or servo-driven machine that performs three tasks automatically:
Pick – A vacuum cup system picks one bag from a stack magazine
Open – The bag mouth is opened by suction cups or mechanical fingers
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.

Every Automatic Bag Placer we ship includes the following standard features:
Built for 24/7 operation in dusty, harsh environments (cement, dry mortar, chemicals). Stainless steel contact surfaces and sealed bearings ensure long life.
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.
Holds 150–300 bags (depending on thickness). Low-bag sensor triggers an alert or automatically switches to a secondary magazine for continuous operation.
Gentle on bags but extremely reliable. Double-cup design handles misaligned or slightly wrinkled bags without dropping.
A photoelectric sensor confirms the bag mouth is fully open before the placement cycle begins. This prevents misfeeds and product spillage.
Works with round, square, or tapered filling spouts. Optional silicone ring adapter for dusty products (reduces dust escape during placement).
Full enclosure with interlocked doors
Emergency stop buttons on both sides
Overload protection on all servos
CE, UL, or CSA certification available
Companies that replace manual bag placing with our Automatic Bag Placing and Packaging Machine typically see:
| Metric | Before (Manual) | After (Automatic) | Improvement |
|---|---|---|---|
| Bags per hour | 300–400 | 900–1200 | +200% |
| Labor per shift | 3–4 workers | 0–1 supervisor | -70% |
| Bag placement failure rate | 2–5% | <0.5% | -90% |
| Product spillage | Frequent | Almost zero | -95% |
| Workplace injuries | Back/shoulder strains | None | -100% |
“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
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.
Our Automatic Bag Placing and Packaging Machine is used worldwide in:
| Industry | Typical Product | Bag Type |
|---|---|---|
| Dry mortar & construction | Cement, plaster, grout, tile adhesive | Valve bag, open-mouth |
| Chemicals | Powders, granules, flakes | Pinch-bottom, valve |
| Food | Flour, sugar, rice, pet food | Open-mouth, gusseted |
| Feed & agriculture | Animal feed, seeds, fertilizer | Woven PP, paper |
| Minerals | Sand, perlite, calcium carbonate | Heavy-duty paper |
| Building materials | Insulation, perlite, gypsum | Valve bag |
If your product is dry, free-flowing, or semi-free-flowing, an Automatic Bag Placer will work for your line.
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
Here is the step-by-step sequence of our Automatic Bag Placing and Packaging Machine:
Magazine feed – Bags are stacked on an inclined or horizontal magazine
Bag pick – Vacuum cups pick the front bag from the stack
Bag transfer – The bag is moved to the opening station
Bag mouth opening – Upper and lower suction cups pull the bag mouth open
Opening verification – Sensor confirms the opening width is correct
Spout insertion – Mechanical fingers or a pusher places the bag onto the filling spout
Bag release – Grippers release the bag; it is now held by the spout only
Fill cycle starts – Filling scale or auger discharges product into the bag
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.
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).

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.
A: Yes. We offer a dust extraction hood and reinforced vacuum cups for dusty environments (cement, carbon black, etc.).
A: Typically 3–5 minutes. Adjust the magazine guides, change the suction cup positions, and select the new recipe on the HMI.
A: 380V / 50Hz / 3-phase (208V, 400V, 415V, 460V available). Compressed air: 6 bar, 300 L/min.
