Small Sorters, many Destinations

Mobile sorters can make outstanding use of limited space – what’s more, they’re flexible in what you can use them for.

For over 200 years; from the first railway lines to the Eiffel Tower lifts and industry 4.0, Fives has been at the heart of industrial revolutions by designing the breakthrough solutions and technologies that make up industry and that the world needs. As the world’s leading partner in supply chain performance, Fives, through its Intralogistics Business Unit, provides and integrates world-class solutions for sorting, warehousing, material handling and advanced automation, serving a wide range of industries.

As a pioneer of digitalization, Fives is always one innovation ahead thanks to its ability to anticipate customer needs and the commitment of its passionate and expert employees, including Fabio Sacchi, New Application Director for the GENI-AntTM sorter. In 2016, he joined Fives with the mission to develop robotic solutions for intralogistics. Since then, he has led a team of expert engineers with the goal to build the next generation of the world’s most flexible robotic sorters. The result is the development of the AMR-based GENI-AntTM sorter, entirely designed and manufactured at Fives Intralogistics SpA in Italy.

What is the thinking behind the GENI-AntTM sorter? “ Due to the pandemic and the acceleration in the switch to ecommerce, retailers and 3PLs need to transform their supply chains, modernise their warehouses and improve their delivery network, especially in urban areas,” he says. “They must now manage unpredictable, more fragmented, and smaller orders in their distribution centres and warehouses, as well as an increasing number of returns.”

Mobile sorters

The GENI-AntTM sorter is the most scalable and flexible solution available on the market today. It can be easily reconfigured and relocated due to its compact design and small footprint. “The implementation of autonomous mobile sorters, capable of making decisions and speeding up processing, allows our customers to move to the next level of integrated automation to improve efficiency and productivity in their facilities. This is the perfect solution for any company facing increasing logistics complexity and labour shortage.”

He goes on to list the benefits that he says the GENI-AntTM sorter can offer to beat its competitors. “Compared to a traditional sorter, a GENI-Ant TM -based system requires 20% less space, over 25% less operation and maintenance costs, and 40% less labour costs, while offering high productivity, and can serve many more destinations. It can be adapted to building constraints and is therefore suitable for postal agency and express courier depots as a stand-alone solution for last sorting points, as well as for retail and distribution centres for shipping to the point of sale or to end customers. At the same time, it can be integrated with other material handling equipment, as an extension of an existing sorter for multiple processing within larger hubs and warehouses.”

The ability and capacity to handle multiple varieties of items is crucial. “It is equipped with two stand-alone cross-belts sorters to transport and sort multiple items. It is capable of handling a wide range of products, such as parcels, flyers, fragile and non-standard items, as well as unusually large parcels up to 1.2 metres long. This range of sortable products also includes extremely small and irregular items that are difficult to sort with other conventional systems, such as soft goods, oddly shaped and unstable packages.”

Fives is about a lot more than sorters, of course, with a product range including conveyors, diverters, sorters, singulators, ASRS and software systems. Mr Sacchi says it was this holistic know-how that led to the genesis of the GENI-AntTM sorter.

He visualises many opportunities for GENI-AntTM sorter customers, describing it as “a future-proof solution that can be easily and quickly adapted to ever-changing requirements. Thanks to its flexibility and modularity it can be adapted to new environments and intralogistics challenges.”

Drive solutions for the bulk goods industry

Whether storing, conveying, weighing and dosing, or loading and unloading, Nord Drivesystems says it develops and produces scalable drive solutions for all sectors of the bulk goods industry. The drives are individually tailored to the customised application, and offer high energy efficiency paired with a robust design.

Large temperature fluctuations, abrasive ambient media, rough operating conditions: Demanding ambient conditions are common in the bulk goods industry. Drive systems used in this sector must be adequately resistant. At the same time, they should operate as energy efficiently as possible, provide easy maintenance and high reliability, and achieve a long service life. Different bulk goods require different plant arrangements that need customised drives.

Bulk goods handling from a single source

Being a long-time partner of the industry, Nord Drivesystems says it knows precisely the specific requirements of the bulk goods industry. The drive specialist globally supports operators of systems for storing, conveying, weighing, dosing, loading and unloading of bulk goods with optimised drive solutions, profound application expertise and technical support.

The powerful drive systems are characterised by maximum reliability, safety and robustness, and ensure smooth operation even in the harshest ambient conditions. Fully featured Nord drive solutions based on a modular system, consisting of frequency inverter, motor, gear unit, couplings, and brakes are selected as the basis. They are combined with solutions individually developed and designed according to customer requirements.

Ultimate reliability

Nord manufactures all gear units – even the industrial gear units up to 282kNM – with a UNICASE housing. An enclosed gear unit housing, which combines all elements of the gear unit is produced from a single piece of material. All bearing points are integrated in the housing block so that there are no sealing surfaces, which are subject to torque and radial loads. This way, the Nord gear units achieve a longer bearing life than gear casings manufactured from jointed parts and ensure efficient power transmission and high tolerance for peak loads and impacts.

Large low-friction roller bearings ensure extremely high axial and radial load capacities; high-precision axis alignment ensures quiet running.

Future-proof

Nord drives are highly reliable, have a long life, are easy to maintain and have a low energy consumption. They thereby help to reduce operating costs and minimise CO2 emissions. The system solutions also meet the requirements for Industry 4.0 applications, and with their integrated PLC functionality allow for condition monitoring and predictive maintenance.

 

Rollers for Energy Efficiency

A warehouse optimised for maximum efficiency isn’t always optimised for minimal energy use, but a veteran rollers manufacturer has a solution.

Founded in 1946 as a specialist maker of motors for fans and washing machines, Itoh Denki became a pioneer in the industry when its founder invented the Motorised Drive Roller (MDR). By putting the motor and gearbox inside the body of the roller, the company was launched into the intralogistics industry. US Post chose to adopt this new roller technology, and then Itoh Denki’s future as a major player was sealed when it introduced brushless 24V technology to conveyor systems. This meant considerably higher safety levels, as the rollers neither snarled body parts nor did they impart potentially life-threatening electric shocks to unwary operatives – unlike the brutal 400V AC motor-driven rollers they replaced.

“The rollers have just enough torque that, if you want, you can stop one roller with your hand,” says Tatsuya Akashi, president of Itoh Denki’s European operations. “But its biggest advantage is that you can make each one-metre-long conveyor independent. In the past, an entire 200m conveyor would be powered to move just one small part, which was a waste of energy. Now we can move only the section of the conveyor which the part is on, saving up to 60% in electric energy.”

Describing MDR deployment as “new technology”, Mr Akashi says half of the existing conveyors in the world are old technology. “Right now, they are being replaced, so our growth potential is huge.” Ecommerce is the sector most suited to benefit, as ambitious short lead times can only be met thanks to the widespread use of MDRs in large DCs.

Wider rollers

But whilst the majority of sales are to businesses handling small parts (up to 50kg) in plastic totes or carton boxes, Itoh Denki also produces a roller with a wider diameter, making it attractive to the automotive sector as it can convey parts weighing up to 500kg as well as pallets weighing up to a tonne.

Mr Akashi believes the company’s claimed 60% energy saving is the highest in the sector, fuelling its growth. “Only in Europe, we were slightly behind our largest competitor in market share,” he says. “In the past five years, we’re doing four times more sales than before, so I think we are now in equal number one position.”

Offering modules featuring 90° right-angle transfer and free angle diverters, Itoh Denki evangelises a diverter-centric approach to sorting. “I have nothing against the crossbelt sorter,” says Mr Akashi, “but we’re talking about a new way of sorting. Today, there are still a lot of old theory believers from the crossbelt era who are stuck to just one way of layout thinking, which can be extremely costly. Take ASRS technology. You replace pickers walking and climbing stairs with a stacker crane weighing sometimes a few tonnes. It can run several hundred metres and acceleration is extremely fast, but the energy used just to take one box or one pallet from the end of the warehouse is very high. I would say that, if you do a circle and use our technology to have a conveyor with lifter storage, you don’t need to run such a big train. So if everybody thinks about energy, we can change. We can think from scratch and make something much more fitting to the need.

Micro Fulfilment

“We don’t just sell the MDR, but have a mindset of helping customers understand and adopt more efficient solutions to improve logistic processes and energy consumption. While the market adapts globally, it can sometimes be hard for well implanted companies that have inventory and engineers experienced on one technology, to adopt a new model.” With the trend moving towards smaller and more local micro fulfilment centres, Itoh Denki seems well-placed to capitalise of the growth of facilities where smaller, more nimble material handling is required.

Durable drives for belt conveyor systems

Nord Drivesystems has specially developed the MAXXDRIVE XT industrial gear unit for the requirements for conveyor technology drives in the bulk goods and mineral industries. It provides output torques of 15 to 75kNm with speed ratios from 6.3 to 22.4 and is offered in seven sizes for powers from 22 to 2,100kW.

The power and speed ranges of the two-stage right-angle gear unit have been specially designed for industries in which low speed ranges are required in combination with high powers – such as the bulk goods and mineral industries. Its robust design makes the MAXXDRIVE XT resistant to dirt and reliable in rough operating conditions. A special sealing concept reduces maintenance. Large roller bearings and centre distances increase the load capacity and service life of the components.

As standard, the industrial gear unit is equipped with a heavily ribbed UNICASE housing and an integrated axial fan. Due to the increased surface and the airflow covers, the cooling airflow is optimised and a very high thermal limiting power is achieved. In many cases, additional cooling is not required.

Individually configured drives

“As with other application areas, our drive solutions for the industry are individually configured for customers according to the modular principle,” emphasises Jörg Niermann, Head of Marketing at Nord Drivesystems. This is based on a comprehensive range of frequency inverters, motors and gear units, as well as coupling and brake systems, each with a wide variety of options. Features such as hydraulic couplings tailored to the particular process or Taconite seals, which effectively protect radial shaft seals against abrasive dust and corrosion, ensure smooth operation.

Nord also offers innovative predictive maintenance concepts for heavy industrial gear units. Nord drives networked via the frequency inverter communicate their status data via the control system or directly into a secure cloud. With optional vibration monitoring, condition changes can be detected at an early stage and predictive maintenance can be scheduled in good time. Performance data recording also ensures optimal system dimensioning as well as continuous condition monitoring of the drives.

 

Solutions for Food and Beverage Logistics

Thousands of installed drive systems are making NORD Drivesystems one of the world’s leading suppliers of drive solutions across all branches of the food and beverage industry. Based on their extensive knowledge of applications and the versatile modular system, NORD drive experts are providing complete drive solutions for all branches of the industry from a single source.

Reliable drive solutions are an essential requirement for the entire value creation chain throughout the food and beverage industry. From storing, conveying and processing of raw materials to process engineering and filling right up to packaging and logistics – drive systems tailored to the specific application are required. They need to balance hygiene requirements, technological requirements and energy efficiency with product protection and demanding environmental conditions such as heat, cold or moisture in an economical way. In order to meet these requirements, NORD Drivesystems designs reliable and high-quality complete systems consisting of geared motors, frequency inverters and intelligent software.

Gentle and powerful pumping

Amongst others, NORD supplies pump drives with special functions tailored to the pumping medium such as high starting torques or soft start. Wall or motor-mounted frequency inverters facilitate decentralised automation concepts and mobile pumps with intelligent control concepts. In combination with the nsd tupH surface treatment, smooth surface motors and two-stage bevel gear unit based drives are created that combine light weight and high efficiency in a large number of variants with corrosion protection and hygienic smooth surfaces that are easy to clean. Even without a fan, they are achieving a considerably better heat dissipation than stainless steel drives while still featuring a similar corrosion protection. These properties are also required for drives in machines and systems for cutting and dosing as well as in CIP and SIP areas. Whether it comes to heating, cooling or freezing – NORD drive solutions are at home in all temperature zones and can be designed for extreme application conditions in cooking and baking lines or deep-freeze systems.

Agitating in all sizes

For processing steps such as agitating, mixing or kneading, NORD is building high-performance gear motors in all sizes with especially resilient output shaft bearings for high loads. For this application area, MAXXDRIVE® industrial gear units with output torques from 15 to 282 kNm are especially suitable. They can now also be equipped with the new SAFOMI adapter: a flange with an integrated oil expansion tank, increasing operational reliability and requiring fewer wearing parts. NORD offers application-specific equipment options that combine high performance and efficiency, specifically designed for pumps, agitators and mixers with high process-related radial and axial bearing loads.

Perfect conveying, filling and packaging

Synchronous motors with frequency inverter and encoder feedback via absolute or incremental encoders enable highly economic and precise positioning applications and dynamic movement of small and large packaging units. NORD implements versatile solutions for horizontal, vertical and inclined conveyors as well as palletising systems, as well as customised drives for filling systems. With the intelligent NORD frequency inverters, soft start, braking ramp, braking and STO functions can be implemented. Multi-encoder operation, during which a frequency inverter can control up to four motors with encoders, is also possible. For intralogistic systems, NORD also offers the LogiDrive concept: a modular system for individual, economical drive concepts that achieve an optimal balance between energy efficiency and reduction of variants.

Space and Speed at Scale

Ecommerce in Europe is expected to be worth €717 billion at the end of 2020. Distribution warehouses and fulfilment centres need to be ready, says an emerging player in the space, writes Paul Hamblin.

In the race for bigger market share, e-commerce companies are opening more locations across Europe. At the same time, offline businesses are increasing their online presence. It follows that the fulfilment centres of today need to get ready to meet increasing demand, not only from online and offline shops but also from the person at the end of the line, the e-commerce consumer.

According to Hristo Urumov, owner of Sofia-based storage technology and material handling specialist STAMH, this is going to be tricky for some DCs unless their managers make changes,
because many are going to receive more orders per day than they can physically fulfil. “Already, a typical online customer is likely to fill their check-out cart with more than one item per online order and it’s a fair bet that they will expect their new purchases to arrive within two days, at most, of making that order,” he points out. “And guess what – they don’t care where the fulfilment centre is located.”

It’s not just the number of online shops that is growing either. The total of items in each product line to be stored and distributed is on the rise, too. Warehouses need to accommodate a growing list of inventory, in some cases without switching location. Businesses know all too well that customer satisfaction is essential to success in the online space, which means a well functioning fulfilment and logistics centre is a vital piece of the jigsaw. Limited picking, sorting and logistics capacity can prevent business expansion because fulfilment centres simply can’t meet the demand.
E-commerce businesses need to act in order to get ready for the upcoming growth.

“There are two ways to grow – to expand the range of products offered or to enter new markets,” says Hristo Urumov. “It’s better to do both.” To solve the puzzle, growing e-commerce business can opt for 3PL or scalable automation solutions to stay in control, he says.

“Outsourcing the problem means losing control over the quality of the fulfilment process,” he argues. “If you use a 3PL, it actually means handing over the satisfaction and retention of your hard-won customers. The ability to affect and control your service to your customers is outsourced to a new partner and you are relying completely on that partner.” STAMH’s owner predicted several years ago that the next step in warehouse development would lie in the refinement of picking automation as a way to meet growing demand and to boost a DC’s capacity to prepare new orders.

He recognises that full automation can be an expensive solution. “In this context, scalable automated modules may be the answer to the growing demand,” he points out. “The engineering solutions of modern warehouses offer space optimisation and picking automation at a speed step by step and hand in hand with the growth of your business.”

STAMH’s engineering team already knows that the modularity of these solutions offer businesses the possibility to make scalable investments, according their optimisation needs. “A lot of companies are opting for partial automaton. They proceed to a full solution only when they actually see the results,” he says. Successful automated e-commerce solutions need to offer space
optimisation, productivity and 100 % picking accuracy, he argues. “They are here to stay and can offer e-commerce business the possibility to break though the wall of growing demand.”
