moduLAN® 800

For almost limitless flexibility LANGGUTH offers its moduLAN® rotary labeler with up to four labeling stations encompassing hot melt, wet glue, and pressure sensitive formats for nearly any container and label shape. Customers appreciate the opportunity to select a combination of label types using single modules, multiple modules, or combination modules. The moduLAN® is offered in three different speed ranges.

Advantages:

  • Highest engineering quality
  • Labelling modules can be combined
  • Tool-less changeovers with quick release components
  • High operator accessibility and easy cleaning
  • Wet glue stations use LANGGUTH’s direct label transfer FVT18 magazine without glue pallets
  • Versatile and simple operation
  • Maximum flexibility and customization
  • Quick changeover

LANGGUTH has developed three moduLAN® modules with distinct number of container plates to achieve both speed and required labelling functions. Plate rotation necessary for the labelling process is performed in continuous mode by a central drive or by individual servo drives tied to each plate. Cameras or special sensors within the labelers ensure non-contact container orientation. Furthermore supplementary coding and control devices can be integrated easily.

Glue pallet – wet glue with traditional glue pallet label transfer

When direct label transfer with the FVT18 is not possible, the moduLAN® is equipped with traditional glue pallets reliably used by the beverage industry for the application for the front, back, patch, shoulder or neck ring labels.

Technical data: (basic)

Speed: Up to 24.000/hour depending on container specs
Labelling: Front, back, shoulder, neck ring
Label length: Up to 180 mm possible
Labels: Rectangular or shaped labels

FVT 18 – wet glue technology

In contrast to the glue pallet technology the LANGGUTH wet glue magazine FVT 18 permits the processing of labels which are longer than 200 mm. Furthermore the FVT 18 offers a significant cost savings and simplicity by eliminating the need for change parts for different size labels.

Technical data: (basic)

Speed: Up to 15.000/hour depending on container specs
Labelling: Mainly wraparound or partly wraparound for cylindrical jars
Label length: Min. 80 mm – max. 400 mm
Label height: Up to 210 mm
Labels: Rectangular or shaped labels

Hotmelt Technology


The glue-saving spray hotmelt system permits speeds up to 60.000 containers per hour and applies wraparound labels onto all kinds of cylindrical containers.

Technical data: (basic)

Speed: Up to 60.000/hour depending on container specs
Labelling: Mainly wraparound onto cylindrical and angular containers
Label length: More than 500 mm possible
Label height: Max. 235 mm
Labels: Rectangular labels made of paper or plastic

Self-adhesive labellers

In addition to product labels, also applies special labels for promotional activities, coloured stickers or ID labels can be applied by self-adhesive dispensers.

Technical data: (basic)

Labelling: Front-, back-, seal Labels and coloured stickers, special labels for promotional activities or ID labels
Label height: Max. 320 mm
Labels: Rectangular or shaped labels made of paper or plastic

Operation:

The labeller works on a rotary principle and can be equipped with different labelling modules. The infeed worm controls the container infeed and creates a defined gap between the containers which matches the pitch of the infeed star. The infeed star guides containers onto the centering plates of the carousel. Then the centering heads fix the containers on the centering plates.

Wet glue module FVT18

In the glueing device of the wet glue module FVT18 the glue is pumped and recirculated over the rotating glue roller and returned via a hose. An even glue film covers the glue roller. The labels are positioned vertically in the stationary label magagine. A vacuum bar picks up the label from the magazine and transfers the label to transports belts. After moving through the belt transport section the label meets the glue roller which applies an even thin film to the entire backside of the label. The label edge is deflected off the glue roller onto the container. The entire label wraps around the container and is wiped tightly to the container.

Wet glue module pallet labelling

In the glueing device of the wet glue module pallet labelling, the glue is guided by the glue pump onto the rotating glue roll via a hose. An even glue film covers the glue roller. The labels are positioned vertically in the label magazine. The glue pallets pick up labels from the magazine; then they are transfered to the pincer roller (or gripper cylinder). The pincer roller transfers glued Labels to the container.

Self-adhesive module

The label is located at the dispensing edge of the self-adhesive module where it is ready for release. The passing container removes the label from the dispensing edge and the self-adhesive labeller transports the next label to the waiting position located at the dispensing edge.

Hotmelt module

During the pick-up glueing process, dots of glue are sprayed onto the container by the hotmelt module. The labels are positioned vertically in the hotmelt label magazine. The passing container pulls the leading label edge out of the magazine using the adhesive force of the first glue dots. Because of container rotation the label is wound around the container. During the lap glueing process the label trailing edge has hot melt extruded from an overlap bar as the label is pulled from the label magazine. During container rotation the overlap adheres to the designated spot on the label body.

To pull the label tight the container is conveyed through wipe-on brushes/press-on rolls which smooth and press the label onto the container surface. Shortly before reaching the discharge starwheel the centering heads release the containers again. Then the discharge starwheel guides the containers from the centering plates back to the conveyor.
