Bag forming, filling and sealing machines

Flow-wrapping machines package products quickly and efficiently in pouch packaging - regardless of whether they are food, pharmaceutical or non-food products.

lubrication-free and low-maintenance motion plastic are the problem solvers in many areas of these machines, e.g. in the drive of the sealing bars, in the bag folder or in the format adjustment of the bag width.

Overview of flow-wrapping machines and products used

Vertical packaging machine with igus hoses and guides shown schematically.
Vertical bag forming, filling and sealing machines (VFFS)
Tubular bag machine with web guidance and two vertical modules for film processing.
Horizontal bag forming, filling and sealing machines (HFFS)

Vertical form, fill and seal machines (VFFS)

Tubular bag packaging machines quickly pack products, whether they are food, pharmaceutical or non-food products.
Vertically aligned, they can also be used in confined spaces. lubrication-free and low-maintenance bearing components such as profile rail systems or spindle lifting tables are used at various stations in these machines.

Products used and application examples
The stations of pouch packaging machines and the products we use are shown below as examples. Among other things, drylin® profile guides, spindle linear tables or iglidur® plastic plain bearings are used in the sealing bar, bag folder or in the format adjustment of the bag width.

1. product dosing

2. bottom film unwinding

3. film run correction | web edge detection

4. film deflection

5. transverse sealing tool (sealing bar)

6. longitudinal sealing tool (sealing bar)

Metal dosing system with articulated arms and brackets for precise motion guidance.

1. product dosing

Wear-resistant and lubrication- and maintenance-free iglidur ® J plain bearings and igubal ® spherical plain bearings in the flap bearing enable reliable product dosing.

2. unwinding of tubular film

At the start of the packaging process, xiros ball bearings enable the reliable and durable unwinding of the tubular film. They enable maximum running performance in continuous operation.

Sensor on a tubular packaging machine monitors the hose guide.

3. film run correction | web edge detection

The format adjustment for film run correction enables maintenance-free dryspin® lead screw technology and drylin® linear tables. drylin® linear guide guide the sensors for checking the print mark and web edge.

Film deflection with several rollers for web guidance in a technical application.

4. film deflection

xiros plastic ball bearings in the film deflector are a cost-effective alternative to metal ball bearings. They are lubrication-free, corrosion-free and low-noise.

Gearbox with e-chain-supported guide and push rods for linear motion.

5. transverse sealing tool**(sealing bar)**

In combination with drylin® R shaft guide and igubal ® rod end, drylin® linear plain films enable maximum running performance when supporting the sealing bars.

Longitudinal sealing tool in a production system with guiding and clamping mechanism.

6. longitudinal sealing tool**(sealing bar)**

In combination with drylin® R shaft guide and igubal ® rod end, drylin® linear sliding foils enable maximum running performance when supporting the sealing bars.

Horizontal flow-wrapping machines (HFFS)

In horizontal flow-wrapping machines, a wide variety of products such as food, pharmaceutical products or non-food products are fed into pouch packaging and packaged. Our linear products such as profile rail systems or spindle lifting tables are used at various stations of these systems to ensure a smooth packaging process.

Products used and application examples
The stations of pouch packaging machines and the products we use are shown below as examples. Among other things, drylin® profile guides, spindle linear tables or iglidur® plastic plain bearings are used in the sealing bar, bag folder or in the format adjustment of the bag width.

1. positioning of the film roll

2. format adjustment of the filling station

3. positioning of the hole punch

4. guidance of the bag folder

5. format adjustment of the labeller

Automated production system with multiple transparent modules and a conveyor system.

User report: Veprotech

A total of 13 drylin® SHTaxes are used in Veprotec's pouch packaging machine for format adjustments and positioning tasks.

1. positioning of the film roll

Manual positioning of the film roll is ensured by means of a drylin® SHT -20-EWM-axis with a driven and a pulled carriage as well as the torque support via a drylin® floating bearing.

Automated machine setup with igus components and a gripping module in a production environment.

2. format adjustment of the****filling station

Automated adjustment in the filling station area is carried out using a reverse drylin® SHT spindle-linear system with a flange-mounted NEMA 17 motor.

4. guidance of the bag folder

drylin® R linear plain bearings guide the movement (opposite directions) during the bag folding process.

Packaging machine with film and conveyor for automated packing.

5. format adjustment of the labeller

The automatic format adjustment of the labeller is performed by a drylin® SHT -20 with NEMA 23 motor.
