Plastic beer bottle labeling technology

All signs indicate that the strong sales of polyester bottled beer will come. So what kind of labeling technology is suitable? What are the options?

First, the characteristics of the component labeler

1. Cold labeling, hot melt labeling and self-labelling It should be said that the component labeler will lead the development of future labeling technology. This multi-function labeler has opened up a new design space for product marketing in terms of promotion and profitability with the diversity of its labeling. The options are almost unlimited. Glass bottles, plastic bottles, wide-mouth bottles, and special-shaped bottles can be affixed with different kinds of labels, including body marks, shoulder labels, back labels, ring labels, and tapered ring necks. Standards, etc., can be labelled cold glue accurately, cylindrical body, can also be affixed to the body ring thermosol. For pressure-sensitive pressure gauges, they can also be labeled with Krones' component labellers after they are removed from the liner. For example, a waterproof plastic label may be applied to the bottle, or the transparent label may add a visually unappealing effect.
The Krones component labeler is based on a new design that allows cold glue labeling, hot sol labelling and self-labeling on one machine. With this set of equipment, the Krones Group company can be close to the beverage industry's highly flexible requirements for different bottles. This kind of multi-function labeler is user-configurable due to the unit module structure. This type of labeling machine has different sizes and is suitable for a variety of different speed ranges. Due to its compact structure, this type of labeling machine needs a lot of space and can easily approach the device from various angles. The performance of the novel machine design in frequently changing labeling not only improves the production efficiency, but also allows the user to obviously feel the cost savings.

2. Up to four sets of labeling systems can be mounted on a single machine Krones modular labelling machines can be equipped with multiple sets of the same or different labelling systems, with up to four labelling systems. Each independent labeling station is affixed to the chassis of the labeling machine and is simply replaced as needed. They are all equipped with independent drive motors, each of which is coupled to the main motor. The variable speed rotation of the bottle is accomplished by a servo motor unit. By eliminating the traditional desktop, it is easier to access the internal structure of the machine to make operation and maintenance more convenient. At the front of the labeling machine, the incoming and outgoing starwheels are available, and they can be disassembled from the large 960-mm bottle turntable.
This labeler can be easily converted to different bottles and labels of different sizes. If it is necessary to replace a set of labeling stations, first loosen the fixed locks, and then fix the pulleys under the mounting station and send them to the storage location for maintenance and testing. Similarly, the new rebranding station and the station's pulleys are pushed onto the plane and fixed.

3. Cold glue labeling station for pre-cut labels The Krones cold labeling station is suitable for pre-cut labels. It is equipped with an inverter-controlled motor. The shell of the labeling station is a stainless steel structure, and the head cover is equipped with a clever locking mechanism. The labeling control device of the target turntable uses a special sealing ring to prevent the influence of external water spray, cleaning agent or spatter.
All bearings in cold labeling stations are lubricated by a recirculating oiler. The oil level indicator determines the viscosity of the oil as needed and prompts the operator for the next oil change. When other labels and bottles are replaced, they can be completed quickly without the use of tools.

4. The Canmatic hot glue labeling station for pre-cut rings is used for pre-cut ring labels. This standard station is equipped with two independent thermosol devices, each operating independently, and the thermostat sets the temperature of the adhesive.
The first thermosol device coats the bottles with adhesive strips in the vertical direction. The adhesive strip next to the bottle leads the label out of the label box to a label during rotation of the bottle. At the same time, the second hot melt device was coated with viscose at the end of the label.
After the label has been rotated with the bottle for one full week, the lap joints stick together. Both thermosol devices and label boxes can be rotated on the bottle table, and the desired position of the bottles of different diameters can be adjusted by the scale ruler on the machine. The label box can hold up to 9000 pieces, and the labeling height can be precisely set by a quick adjustment mechanism.

5. The Contiroll type labeling station for roll-to-roller rings can accurately cut the roll-type ring label and attach it to the bottle body. The standard station is driven by a variable-frequency control motor. Its structural components include a label feed control and cutting device, a glue application station, and a vacuum-type cylinder label transfer drum that transfers the label to the bottle body. The conveyor roller continuously pulls the label from the roll. Here the transmission speed matches the length of the label, and the parallel mounted trajectory tracking controller ensures that the label strip remains in a straight line. Rotary knife with separate electric heating cut labels. A computer-controlled servomotor ensures the correct cutting position of the label.
Each end of the label has a narrow edge of hot glue. After aligning the two narrow sides, heat the roller to attach the label. The label is transferred to the bottle by adhesive tape at the top. This tape also ensures precise positioning and avoids misalignment of the label. As the bottle rotates while the label is being transferred, the label is straightened.
The adhesive surface at the end of the label also ensures reliable adhesion. When the bottle diameter changes, the labeling station adjusts its position on the horizontal slide. If the paste height changes, the labeling station motor adjusts the height. Due to the use of digital counters, the repeatability of various settings when changing products is high.

Second, self-adhesive APS2 labeling station

The self-adhesive APS2 labeling station is dedicated to the precise labeling of adhesive labels. It is equipped with a low-wear servo motor to match the labeling station with the labeling speed. The bottom station tapes and labels are fed to the bottle via an infeed and pull roller assembly. Two separate motor-driven label unwinding and winding mechanisms for the backing tape, buffer systems at the entrance and exit continuously rewind the label roll.
The label is peeled off at its broken edge and then it is accurately displaced onto the bottle. In order to adjust the position of the label and when changing different labels, the entire labeling station together with the label roll can be moved through four or six axes. Because each shaft has a reference scale, the repeatability after adjustment is high. The two label reels inside the station are mounted horizontally, so there is no need to consider the replacement of the bottom tape.
An additional device can be used to automatically switch the labelling tape from reel 1 to reel 2 . The reel carriage can be moved up to a vertical position and it is very convenient to replace the reel.
The label component labeler is the future investment direction of the beer industry.
