Utmost in Attractiveness and Safety

Made Possible by the New Generation of Innoket Roland Labelers

Dr. Joachim von Meyer*

For some the focus is on an attractive appearance, for others safety is top priority. We're talking about suitable dressings for small containers. While a good looking and attractive outward appearance of small bottles is of prime importance to the perfume industry and beverage trade, the requirements of the pharmaceutical industry extend far way beyond these criteria where in extreme cases labels are bearers of vital information. It goes without saying that it is essential that the labeling system implemented have the proper precision capabilities. The new generation of Innoket Roland labelers from KHS Anker are capable of producing the utmost in labeling precision and superlative eye-catching appearance.

All Kinds of Little Containers

All sizes of small containers with diameters of 15 mm and up can be labeled without difficulty. Beginning with phials. Container conveying, and in this context, container spacing in the labeler presents a challenge when labeling small containers.

Special Solution for Exact Spacing

Normally, the containers pass through a feedscrew in the direction of the infeed starwheel. Separation and thus exact spacing is the problem area of small container processing. The second difficulty: As a rule, a screw cannot convey extremely small and very short containers since even the screw bearings are too high for processing miniature bottles. For the reasons mentioned, KHS Anker has developed a very special system that makes it possible to space containers without the need of a feedscrew.

The special solution: An S-shaped curve guides the containers to the infeed starwheel. This curve can be individually adapted to various container sizes. The containers are fanned out. Gaps are created. A saw-toothed infeed starwheel engages in these gaps. Small round as well as small square containers are thus separated with ease.

Double Flowgate

A double flowgate makes allowances for the sensitivity of the small containers as they enter the Innoket Roland. Two flowgates installed in succession reduce the accumulation pressure and ensure reliable conveying.

Fast Format Part Changeover

Various infeed starwheels are used depending on the diameter of the containers to be processed. Quick-action fasteners make starwheel changing absolutely trouble-free and thus fulfill the so very important customer demand for fast format part changing.

Turntables must also be changed when changing over to other sized containers. Maximum labeling quality can be achieved – for square containers in particular – if there is no "twisting" on the turrets. For this reason, the exact container dimensions are cut into the container turrets. Only star grip locking screws are used to fasten the turrets. No longer needed turrets can be removed and replaced with new product-specific turrets simply be releasing the star grips. A fast and easy method.

All considered, the time required to change over the new-generation Innoket Roland labeler proves to be shorter than that of traditional machine equipment due to the lack of a feedscrew. The Innoket Roland is ready for new labeling options within a period of 15 minutes at the most.

Wet Glue Labeling...

This new generation of labelers is capable of wet glue labeling as well as self-adhesive labeling and a combination of both. The wet glue labeling process removes the label materials from the label magazine by a glue segment to which glue has already been applied by the glue drum. The glue segment runs past a gripper drum. The gripper drum pulls the label off the glue segment by means of special grippers and transfers it by its glued side to the container. The gluing technique in this instance applies glue over the entire label surface. It goes without saying that maximum labeling reliability is ensured.

... Or Self-adhesive Labeling?

Rollfeed label materials are used for adhesive labeling. This material is fed to the dispensing edge by reversing rollers. A final extremely sharp bend causes the label to peel off the label web for transfer to the container. A sensor scans the containers to determine the label dispensing time point. The moment it completely recognizes a container, the label web is advanced and a label is dispensed. A second sensor located in the labeling station regulates the exact distance between label applications.

Autosplice System for Increased Productivity

Automatic reel changing by means of an autosplice system is available as an option. The beginning of the spare reel is automatically attached to the spent reel as soon as the end of a label reel is reached. Uninterrupted production operation can thus continue without decreasing the output. The result is a significant increase in productivity.

Best possible labeling quality is thus guaranteed for both wet glue as well as self-adhesive labeling. The containers are held securely in place at the top and bottom in the rotary part of the machine. Maximum labeling precision is achieved.

Post-applicator Belt Unnecessary

Labels applied by means of the wet glue labeling process are normally pressed firmly in place by a post-applicator belt. A post-applicator belt is not required to ensure that labels of rectangular containers are properly seated. When a post-applicator belt is used for small, round containers, there is a likelihood that mini containers will fall over as soon as they begin to rotate. The special KHS Anker solution: Labels of the wet glue labeling process are applied by brushes and rollers installed in the machine. In any case, a post-applicator belt is not required for self-adhesive labels due to their strong adhesiveness.

Label Check

The labels are inspected after the labeling process. There is a choice of two options here. The first option checks for missing labels and if the labels are properly seated. Camera inspection is the second option. The label of each container is compared with a model image stored in a computer. This makes certain that the correct label has been applied to the container. A very important aspect for the pharmaceutical industry. Wrong labels inadvertently placed in the labeler by a machine operator are thus unfailingly identified. This rules out in advance the disastrous consequences of erroneously marked medicine.

Stability Through Neck Guidance

The lack of stability and the nature of thin-walled materials of miniature containers present a problem when it comes to transferring them to downstream machines. In order to ensure container stability, it is possible to implement special neck guides at the transfer points in the system and to the following line components. When implemented, this option holds the containers securely by their necks during conveying.

Integrated Control Cabinet

All of the components mounted on the base plate of this new-generation labeler are made of stainless steel. Among the advantages are long service life, easy cleaning, and high hygienic safety. A further advantage of this new generation of labelers is the integration of the control cabinet in the machine paneling. The lack of additional wiring between the machine and the control cabinet facilitates machine installation and reduces possible sources of error.

Continuous Signal Exchange

The new-generation Innoket Variant RF labeler is frequency controlled. The labeler speed is automatically adapted. There is a constant exchange of signals among the machines installed upstream and downstream to the labeler. The labeling speed is increased if, for example, there is an insufficient number of containers on the way from the labeler to the packer. Conversely, the output speed is reduced accordingly in case of container backups.

Integrated Safety Clutch

Both the infeed and discharge starwheels are equipped with safety clutches. If, for example, the labeler is blocked by broken glass then a safety switch automatically switches off the machine. This prevents labeler damage and wear.

A Versatile Labeler

The various machine sizes of the Innoket Roland product line are designed for an output capacity range of 2,000 to 36,000 containers per hour. Up to four labeling stations can be installed. From phials to rectangular and round containers of various diameters, from glass containers to small PET bottles – they're all doable. A truly versatile labeler for miniature containers – with maximum labeling precision and best possible labeling reliability.
