DU - Automatic transparent label dispenser

DU25, DU45 & DU60 Transparent and Opaque Label Dispensers

The DU25, DU45, and DU60 are electronic dispensers designed for the rapid and repetitive distribution of self-adhesive roll labels. Their mechanical sensor system automatically separates the label from its liner and presents it directly to the operator.

Particularly suited to transparent labels, these dispensers offer a reliable solution where optical detection systems may be less effective.

Automatic liner distribution and separation

The DU25/45/60 allow:

• automatic label removal

• immediate presentation to the operator

• the automatic rewinding of the liner

This system ensures a smooth and continuous distribution to the labeling stations.

Detection by mechanical probe

The system relies on an adjustable mechanical probe which allows:

• to detect the presence of the label

• to work effectively with transparent labels

• to adjust the stroke according to the length of the labels

• to ensure a constant distribution

This detection method makes these devices particularly versatile.

Compatibility and capacity

The DU range is available in three models:

• DU25: up to 63 mm wide

• DU45: up to 114 mm wide

• DU60: up to 152 mm wide

These distributors accept:

• reels up to 225 mm in diameter

• a standard 76 mm chuck

They are compatible with both transparent and opaque labels.

Key Benefits

• automatic label dispensing

• reliable mechanical detection

• automatic liner retrieval

• compact and robust solution

• suitable for industrial positions

Advantages of DU25, DU45 & DU60 label dispensers

The DU25, DU45 and DU60 were designed to offer a simple, reliable and efficient solution for the distribution of transparent or opaque self-adhesive labels in an industrial environment.

Thanks to their mechanical probe detection system and robust design, these unwinders facilitate the operator's work and improve productivity on repetitive labeling stations.

Automated distribution and time saving

The main advantage of the DU25/45/60 range lies in its automated dispensing system using a mechanical sensor:

• The label is automatically separated from its liner

• A new label is presented after each removal.

• continuous and regular distribution

• Reduction of manual handling

The operator no longer needs to peel off the labels one by one, which saves time and improves efficiency at the workstation.

Mechanical detection ideal for transparent labels

Unlike optical detection systems, the DU range operates using an adjustable mechanical probe, which allows:

• A reliable distribution of transparent labels

• An adaptation to different label formats

• A simple adjustment of the stroke according to the length of the thumbnails.

This system guarantees consistent distribution even with labels that are difficult to detect optically.

Automatic liner separation and clean workstation

The DU25/45/60 unwinder incorporates an automatic recovery of the backing film system.

The liner is:

• automatically separated from the label

• directed towards a retrieval reel

• automatically rewinds during use

This device helps to maintain a clean and organized work area, while preventing the accumulation of waste around the labeling station.

Ease of use and ergonomics

The DU25, DU45 and DU60 dispensers are designed for simple and intuitive use:

• Can be used with one hand

• Quick coil installation

• Easy adjustment of the mechanical probe

Their compact size and light weight also make it easy to move the device from one workstation to another.

Robustness and industrial stability

The DU25/45/60 distributors are designed to withstand demanding industrial environments:

• robust and durable structure

• Resistance to wear and repeated handling

• Retaining flanges ensuring coil stability

This design ensures a smooth and stable distribution even during intensive use.

Versatility and reel capacity

The DU25 – DU45 – DU60 range offers broad compatibility with different roll formats:

• Three widths available: 63 mm, 114 mm and 152 mm

• Maximum outer diameter: 225 mm

• Standard chuck: 76 mm

This versatility allows the dispenser to be easily adapted to the different consumables used on production lines.

Productivity and performance

• Automatic dispensing of transparent or opaque labels

• Direct presentation of the label ready to be applied

• Reduction of repetitive handling

• Suitable for industrial labeling stations

Simple, robust and efficient, the DU25, DU45 and DU60 provide a reliable solution for optimizing the distribution of self-adhesive labels in industrial environments.

Use of DU25, DU45 & DU60

The DU25/45/60 are designed for the automatic dispensing of roll labels at production, packaging, and logistics stations. Once the roll is installed, the device automatically presents the next label as soon as the previous one is removed.

Setting up and loading the reel

1. Place the spool on the hub with the unwinding direction upwards

2. Tighten the knob on the rear rod to secure the spool

3. Cut off the ends of the labels and the liner

4. Pass the belt under the first drive roller

5. Position the strip between the metal washers of the second roll

6. Separate the first label from its liner, then pass the label under the last roller, between it and the recovery surface.

7. Guide the liner towards the lower reel and secure it with the retaining rod.

8. The dispenser is ready

Using the label dispenser

1. Plug in the device and then turn it on with the ON/OFF button.

2. Retrieve the first label: the next one will appear automatically.

3. Adjust the mechanical probe to set the stroke and adapt to the length of the labels
