Special options
Below you will find a list of various integrable functions. Click on the respective item to display further explanations. Please note that this is only a small selection and that further options are available. We would be happy to assist you in configuring a machine for your products and requirements.
Optionally, a horizontal bag conveyor magazine can be selected instead of the standard stack magazine, into which the bags are inserted in a fanned-out arrangement. Separation is carried out by means of driven PU round belts and rotating brush rollers.
Automatic central lubrication minimizes maintenance requirements and ensures constant lubrication of the mechanics, reducing wear and downtime and enabling a long service life.
A printing system can be integrated as an option to label the bags with the expiration date, batch number, and other production-specific information. You can choose between hot stamp printers and continuous inkjet printers, e.g., from KEYENCE or Videojet.
If you have preferences for a specific printer model or would like to use an existing model from your production, we will be happy to check the compatibility of your desired device with our packaging machine and integrate the system into your new plant if possible.
If the zippers on the bags are to be opened by machine, we integrate a mechanical zipper opener at the second station of the machine, which first pulls apart the bag flap at the top using vacuum suction cups, then lowers the zipper tool and pulls the flap apart so that the closed zipper is opened.
For heavy package weights, this optional roller conveyor integrated into the machine relieves the lateral bag grippers to enable safe handling of the bags.
The product vibrator pneumatically taps the bag from below at the filling station to distribute and compact the product more evenly, preventing excessive fill levels and product contamination between the sealing jaws.
When filling at high speeds, dividing the filling process into two steps using an additional filling station can increase performance and prevent blockages in the filling hopper. Alternatively, different products can be used with separate dosing systems at the filling stations (e.g., a chunky product and a liquid additive).
If the zippers on the prepackaged products are to be sealed, a mechanical zipper sealer is integrated into the machine. A sealed zipper reliably prevents fine-grained products from becoming lodged in the pressure seal, for example, which can mean that the package can no longer be resealed by the end consumer if the zippers are open.
Bags that could not be filled, for example due to an error during opening, are ejected from the machine before sealing by means of the optional empty bag ejection system using a separate ejection chute and can be returned to the magazine or filled manually.
Similar to the ejection of empty bags, the optional empty bag circulation function ensures that empty, unfilled packages are not sealed and are discharged via the integrated discharge conveyor belt together with the regular finished packages. However, the packages are not released from the machine via an ejection chute, but remain inside the machine and are automatically fed back into the packaging process.
In order to reduce the packaging volume and thus the transport volume, an optional bag air exhaust system can be integrated so that the bags are pressed together by two pneumatically driven exhaust sponges before sealing, thereby forcing air out of the bag.
To reduce the packaging volume or the oxygen content in the package in order to protect the product from oxidation, the optional simple vacuuming process using an air lance and vacuum pump removes most of the air from the package before the bag is sealed. Alternatively, complex vacuum chamber carousel can be used for maximum vacuuming.
Vorgestanzte Eurolöcher können beim Öffnen von Beuteln speziell in Verbindung mit geschlossenen Zippern, die maschinell geöffnet werden müssen, zu Prozessfehlern führen. In dem Fall empfiehlt es sich, das Aufhängeloch erst im letzten Schritt des Abfüllprozesses herzustellen. Der optional integrierbare Eurolochkrimper stanzt hierbei ein Euroloch oder ein — Aufhängeloch mit beliebiger Form — in die Siegelnaht des Beutels.
Our rotary pouch filling machines are based on 8–10 stations arranged in a circular configuration, where the respective process steps are executed sequentially.
The pouches, which are loaded into the magazine by the operator, are mechanically picked up (or fed) and transferred to the rotary mechanism. At the first station, the pouches are held by side grippers that secure (or fixate) the pouch until the last station (the One-Touch principle—without repeated gripping and releasing).
The width adjustment of the grippers for new pouch widths is performed tool-free by manually adjusting a central setting handwheel. The grippers at all stations automatically adapt the width, which significantly reduces changeover times and allows for retooling without requiring highly specialized technical expertise.
The operator-friendliness continues with the intuitive menu navigation, while a traffic light beacon indicates the respective operating status. The display, optionally available in German or English, allows for the activation and deactivation of individual functions (e.g., Zipper Opener ON / OFF), simple creation and saving of new programs, testing of individual machine functions, and a test menu for monitoring the inputs and outputs of the PLC (Programmable Logic Controller).
The machine is fully equipped with transparent safety doors and interlock mechanisms (or interlock guards) to ensure the safety of the operating personnel.
The product-contact parts as well as most components manufactured from stainless steel are executed with a mirror-polished finish for hygienic reasons, ensuring minimal product adhesion.
Die rotierenden Einzelbeutelmaschinen ist mit unterschiedlichsten Beuteln kompatibel, wie etwa Doypacks oder Flachbeuteln sowie Klotzbodenbeutel, Kreuzbodenbeutel oder Blockbodenbeuteln kompatibel (ohne rechteckige Beutelöffnung — keine Seitenfaltenbeutel).
The filling of the pouches can be done either automatically, for example via multihead weighers or counting machines, or semi-automatically (manually).
Rotary packaging machines are suitable for a wide range of products. In the field of bulk goods and granulated products they reliably process animal feed such as dog and cat treats, dry food, and chews, as well as nuts, beans, and dried fruit. Coffee, coffee beans, cocoa nibs, confectionery, snacks, chips, croutons, spices, grains, rice pellets, and muesli can also be filled efficiently and precisely.
For coarse or chunky products such as frozen vegetables, seafood, ready meals, fruit pieces, potato products, meat, and fish products, the machines also offer a high level of process reliability. Baked goods such as bread chips, as well as chemical granulates, fertilizers, and pellets in the non-food sector can also be processed without any problems.
In addition, the systems are well suited for moist or pickled products such as olives, cucumbers, kimchi, wet pet food, marinated goods, ready-made sauces and pastes, especially in combination with a suitable pump station.
For vacuum-sealable products such as smoked goods, dried specialties, or generally sensitive products that require special protection, the optional vacuum chamber extension and venting functions offer an optimal solution.
For Powders based on its linear design and the option to integrate a checkweighing station for automatic readjustment of our screw feeder, as well as the optional lift-fill function for dust reduction, we recommend our Machine Series Mini Linear.
