Krones Contiroll labeler with obvious advantages

Labeling is one of the widely used labeling methods in the beverage industry. Whether it is glass, plastic or metal containers, the ring logo can provide more places for various advertisements and product introductions. The labeling machine can automatically affix the ring body to round, oval, square, rectangular, and polygonal containers. The label materials are mostly different types of plastic films, and paper labels can also be used.

The Krones Contiroll labeler enables hot or cold adhesive labels. And this labeling machine adopts a rotary labeling method, and equipped with a labeling station with excellent performance. The labeling station can cut reel labels very accurately, as well as transport and paste the ring labels. Computer-controlled supply rollers and rotary cutters can cut labels cleanly and accurately. Depending on the material of the label, use hot glue or cold glue.

Advantages of the Contiroll labeler system ● Large capacity label rolls reduce the operator's labor intensity to the minimum;
● Accurately position the container by centering and centering the bottle holder to ensure accurate labeling;
● The glue consumption is very low;
● Short time for changing containers or labels;
The modular structure has a very high degree of flexibility;
● Can be updated at any time.

Contiroll labeler operating principle This labeling machine is a continuous operation of the device can automatically adjust the container's inlet and outlet flow conditions. The containers conveying the fruit material from the inlet conveyor belt are separated by the inlet screw by a certain distance in accordance with the pitch of the inlet starwheel, and then the inlet starwheel conveys the containers to the container turntable. When the container is fixed to the middle holder and the bottle holder, the container starts to rotate.
The speed of the indexing roller can be adjusted according to the required length of the tag to ensure continuous tag pull. The standard cross roller device ensures optimal feeding of the label film. Computer-controlled servomotors provide the correct position for the label cutting. At the same time, the independent heating of the rotary drum can ensure the correct cutting.
The glue roller applies hot glue strips only to the leading and trailing edges of the label, so that the glue consumption is lowest. The tape applied to the first side can accurately and effectively transfer the label to the container. Since the container is always in the rotating state during the conveyance of the label, the label can be smoothly and closely attached to the container. Strips applied to the trailing edge can form a good label lap seal.

Applying hot glue on the front and back side This is the standard method of applying glue. Since only a narrow strip of hot glue is applied on the first and the trailing edge of the label, the glue used for this glue application has the lowest consumption.
Apply cold glue to the entire surface When pasting paper labels, you can use cold glue on the entire surface. Practice has proved that this paste method is effective. The label on the container can be lap sealed or not.

Labeling station The labelling station for this device is controlled by a servo motor. Equipped with a marking roller for controlling cutting points, a cutting device, a glue station and a vacuum label drum for conveying labels.
You can add a labeling station when running at high speed or pasting two labels.

Container turntables Round containers This labelling machine is equipped with the same bottle holder on a spoke wheeled turntable. Practice has proved that this design of the Krones rotary labeler is a very effective structure. Depending on the requirements, it can be equipped with 32 bottle holders. When labeling a round container, a servo motor drives the bottle holder through a toothed belt. When sticking containers of different diameters, the speed of the toothed belt can be easily adjusted on the touch screen. The shape of the surface of the bottle holder matches the shape of the base of the container; when changing a new container, the bottle holder can be replaced without using a tool.
Special Shape Containers In addition to accurate centering, when special shape containers are attached, special control of the rotation of the bottle holder is required to ensure a good label attachment position. In order to achieve a high degree of accuracy, it is possible to use a turnaround and an interchangeable cam-shaped bottle holder.

Operation A large, high-contrast color touch screen makes operation easier and more convenient. During operation, current production data such as container and label types, machine speed, and operating hours are displayed on the screen, and data can be input into the production line storage system through the interface or printed out through the printer. All functions are displayed in concise graphical form and can be selected in the relevant language. Access to important production settings requires a password, and only designated personnel can access it.
The operation of the labeling station takes place via a liquid display with keys. All settings and functions can be restored or changed.

Interchanging and Converting Label Volumes Manually Attaching Label Volumes When converting a label volume, the operator needs to connect the end of the first label volume with the head of the second label volume so that each conversion does not Need to re-assemble the label roll into the machine. The cutting table is mounted on the labeling station for manual cutting.
Automatically lapped the label roll The label roll can be fully automated with an additional device. The machine does not need to be stopped. The end of the first label roll can be attached to the head of the second label roll.
Conversion This labelling machine can be easily converted to different container and label types. For the first use of the tag, all parameters can be programmed and stored via the auxiliary menu on the liquid display screen.
When the labeling height changes, the entire labeling station can be vertically adjusted; when the container diameter changes, the entire labeling station can be moved horizontally. Through a crank with a counter. The labeling station can be adjusted very accurately and repeatedly.
Thanks to the patented system of marking stop machines, the container guides can also be quickly adjusted according to the inlet screw that conveys the different container diameters. Each set of transmission parts is marked with colored dots and numerals; the star wheel and the center guide are equipped with a quick-release locking mechanism. The height adjustment of the device is electric and can be locked automatically. The middle collar and the bottle holder are equipped with one-handed locks. Due to the above equipment, the conversion time is greatly shortened.

Additional Devices This labeler can add additional devices to achieve special labeling requirements. Different attachments can satisfy the user's different labeling effects.

Stabilizers Prior to filling, compressed air is filled with relatively flexible containers using specially constructed centering sleeves to enhance the stability of the container.

Clamping Star Wheels The use of the inlet and outlet star wheels of the clamping structure has obvious advantages. The center guide plate is not only omitted, but the star wheel does not need to be replaced when the diameter of the container does not differ by more than 20 mm. Clamping stars can also be used for container exclusion in automatic labeling inspections.

Heat Shrink Device The heat shrink device is mainly used for the shrinkage of a round container or container. It is heated by a heat fan so that the label can be thermally shrunk according to the shape of the container. The container is always in a rotating state during the heat shrinking process, the heat shrinkable turret is assembled at the outlet of the apparatus, or the heat shrinking station is assembled on the conveyor belt.

Self-adhesive labeling station Thanks to Krones' modular component system, an AUTOCOL self-adhesive labeling station can be added to this labeling machine. In this way, sealing labels or similar labels can be glued very accurately.

Garantomat type labeling station The labeling station can directly put a set of label on the container, and the heat shrinkable label can seal the bottle. As an auxiliary device, the installation position of this labeling station can be either at the inlet or outlet.

Blocking Pressure Relief Devices For specially shaped or unstable containers, a plugging pressure depressurization station and a clutchable screw need to be fitted at the machine's inlet. In this way, the container can be smoothly fed into the labeler.

Checkmat-type inspection station This photoelectric detection device prevents unlabeled containers from entering the product stream. This device can also detect filling and capping conditions. By removing the star wheel, clip wheel, or push block, it is very easy to get rid of unqualified products.
