Packaging machines for confectionery and snacks

Packaging confectionery with more flexibility

Modular packaging machines for your diverse product portfolio

With so many different and frequently changing products, flexibility is the key to success in confectionery packaging. For over 50 years, Schubert has been developing and producing modular automation technology for the flexible packaging of confectionery such as chocolate, biscuits, bars, pralines, ice cream, nibbles and savoury snacks. Our passion for innovation drives us to continuously develop new and even better solutions – delivering a clear competitive advantage to our customers.

We know that the confectionery sector is facing a number of changes. Rising costs for raw materials and energy are having a significant impact on the already fierce competition. Consumers’ growing health and environmental awareness is creating new demand for sugar-free varieties and more environmentally friendly packaging. The implementation of legal requirements such as the Health Claims Regulation is another contributing factor.

Confectionery manufacturers not only need to adapt to new types of products and packaging, they also have to establish highly efficient, adaptable packaging processes. With our intelligent and highly flexible automation solutions, you can master these complex requirements when packaging your confectionery.

Automation and robotics

Mastering flexibility with modular solutions

In confectionery packaging, machines and lines should adapt to your processes – not the other way round. This is why we focus on modular, robot-based automation solutions. Our packaging machines for confectionery and snacks support your production process with flexibility and outstanding efficiency.

Our robot-assisted top-loading machines (TLM) dependably perform all the operations involved in picking and packing chocolate bars, pralines, biscuits, cakes, crackers, crisps and many other products.

Customised robotic tools ensure gentle and efficient handling of products, reliable and continuous line operation, and minimal waste due to breakage or incorrect positioning.

Whether for primary or secondary packaging, our systems can easily handle frequently changing formats and different packaging materials – ranging from conventional to fully recyclable.

 

 

Fully automated handling with a pick & place line

Automation with pick & place machines enables you to benefit from a cost-effective and competitive process when packaging confectionery and snacks. Schubert’s packaging lines also ensure an entirely future-proof solution thanks to their flexible conversion and expansion options as well as their long service life.

With proven innovative strength and in-depth industry knowledge, we can achieve the very best for you with our pick & place technology. All components from a single source, as well as perfectly coordinated and integrated solutions, ensure long-term competitive advantages for your company.

Robots are at the heart of every pick & place packaging line. Depending on specific requirements, they are selected from variants in either Scara or Delta design and equipped with customised, quick-change tools.

The counterflow principle in picker lines, patented by Schubert back in 1996, is now standard throughout the industry. Tray destackers and chain conveyors complete the overall system. Special image processing systems ensure optimal quality assurance.

Assortment configuration and design with packing lines from Schubert

Our packing lines for packaging confectionery work with several lateral feed belts. This allows you to run a variety of products in the packaging line simultaneously. The pick & place robots can be flexibly programmed to always pick the right products from the infeed belt, always place them in the right position in the pack – and therefore pack a wide variety of assortment packs quickly and easily. This technology has proved extremely successful, for example, when packaging praline or biscuit assortments. The advantages of pick & place machines, such as simple scalability and optical quality control through image processing systems, can of course also be applied to our packing lines.

Processintegration

Confectionery packaging with seamless processes

In addition to the final packaging of confectionery, Schubert offers solutions for the integration of primary confectionery packaging tasks by combining both processes into one compact system.

For example, our Flowmodul flow-wrapping unit can be seamlessly integrated into the TLM line to pack both bare and tray-packed confectionery into flowpacks.

To integrate other primary packaging solutions into the TLM technology, the Transmodul transport robot seamlessly bridges the interfaces between the respective packaging processes.

As a key technology, the Transmodul also offers the possibility of linking packaging functions from different machine manufacturers.

An example of a packaging process: versatile, flexible and fully integrated.

A possible structure of a Schubert packaging solution

Up to 1620 freshly baked biscuits are conveyed per minute on a wide product belt directly from the production line to the 72m-long TLM packaging line. It consists of two identical flowpackers connected in series for primary packaging of the biscuits into flowpacks, as well as two identical sub-machines, each consisting of a cartonpacker and a Flowmodul, for secondary packaging either into cartons or into multipack flowpacks.

The biscuits are stacked in each of the two flow-wrapping machines using pick & place robots and placed into the Flowmodul’s feed chains. Schubert’s image processing system, developed in-house, ensures that only products of flawless quality are picked up and placed into the feed chains.

Immediately after being packed into flowpacks, the products are transported on belts to the sub-machines for secondary packaging – which are also fully integrated into the line – where they are packed either into flowpack multipacks or cartons.

A total of 32 different packaging formats can currently be accommodated on the line. The customer can easily have the line set up for additional or other formats at any time.

Scaling, combining, checking, varying

These integrated process steps can be adapted in many ways:

  • Scalability: Simple upscaling or downscaling of the system – production capacities can be flexibly adapted thanks to the modular design.
  • Combinability: Quick changes to the product range – with TLM packaging machines, a wide variety of products can be easily combined to create product assortments in changing packaging sizes.
  • Quality: Reliability thanks to image processing software – cameras for detecting rejects and defects can be easily integrated into each process step, ensuring virtually 100 per cent quality.
  • Variants: Quick adaptation to new materials – whether plastic, paper, non-adhesive cardboard boxes or recycled materials: Schubert machines and systems are equipped for any material.

The Flowpacker – the flow-wrapping machine for maximum packaging variety

The Flowpacker combines two key benefits in confectionery packaging: easy handling of a wide variety of packaging types and trouble-free processing of new, sustainable materials. With the Flowpacker flow-wrapping machine, you can achieve the quickest response times and very quick adjustments with minimal effort. As a fully integrated solution, the Flowpacker saves up to 70 per cent space – with extraordinary flexibility. You can switch between sealing technologies, product formats, or proven and new packaging materials virtually at will, easily and quickly. This makes the Flowpacker the tool of choice for positioning yourself for the future: flexible, durable and reliable.

Compared to mechanical flow-wrapping machines with conventional feeding, the packaging system from Schubert offers unique customer advantages when it comes to confectionery packaging. A TLM frame from Schubert seamlessly combines pick & place robots with a horizontally positioned flow-wrapping unit to create a single line. The infeed system features pick & place robots, replacing long infeed belts. This enables the flow-wrapping process to be compactly and completely integrated into the line. State-of-the-art image processing technology in interaction with the entire line enables machine efficiency levels of up to 99 per cent and virtually 100 per cent product quality.

Image processing

Automated quality control via advanced optical systems

In addition to robot technology, state-of-the-art vision systems are also at the heart of our machines. Vision systems ensure high and reliable machine performance at every stage of the process – from pick & place to end-of-line inspection. Confectionery manufacturers therefore benefit from both high process speed and precision.

A continuous process flow without unplanned downtimes is an important factor when it comes to the competitiveness of any production. Especially confectionery packaging, with its high number of variants, slight deviations in product appearance and high assortment flexibility, needs a good eye for fast-running processes – a job that is no longer possible for humans at modern line speeds.

Image processing for confectionery

In the future, Schubert will also use neural networks and AI to control products such as confectionery and snacks. A simple and clear allocation is not always a given – especially for products with many process parameters. Statistical processes with a complex system of random samples and inspections are therefore replaced by 100 per cent control.

The vision system’s AI achieves what humans and conventional systems can no longer do. Without programming, it recognises relevant product characteristics and automatically determines evaluation parameters.

Packaging development

Getting the most out of your cartons

The market trend for sustainable packaging materials will continue in the future. In confectionery packaging, plastic can now often be replaced by cardboard – for both primary and secondary packaging. For example, dividers for stacks of biscuits can also be easily created in a cardboard tray. Carton trays for wrap-around save plastic film and create additional space for marketing communications.

To automate the packaging process, you need materials that are machine-compatible. At Schubert, we are experts in cardboard packaging of all kinds. Wherever the use of plastics is not urgently required for reasons of impermeability or product shelf life, packaging made of cardboard is already being used today: for example, perforated masks for cups, trays with integrated dividers, scaling ramps for biscuits, inserts for product fixing or wrap-around cartons for bottles.

We are convinced that although plastic film have their justification for certain applications, it is often possible to develop a machine-compatible functional alternative made of cardboard for the confectionery packaging. For your packaging development, we at Schubert draw on a pool of basic designs and a variety of packaging types. Drafts are created and coordinated using a CAD system. During this process, we also manage communication and coordination with the manufacturer and packaging supplier.
