To keep pace with consumer expectations and enable direct-to-consumer delivery, retailers and manufacturers are rapidly evolving their distribution center strategies. Many are migrating their fulfillment operations toward mega-cities and high-population centers to enable on-time delivery, making the efficiency of these DCs more important than ever. But things are also evolving inside the four walls to maximize the available space and optimize product and employee workflows. This "warehousing compression" strategy requires better utilization of vertical spaces and new automation equipment to support this upward trend in high-density facilities.
Some innovative approaches to vertical expansion include facility upgrades to include mezzanines, multiple floors and, most importantly, vertical conveyors to facilitate the movement of product throughout these various levels. Whether it's footprint, flexibility, throughput or ergonomic consideration, each facility has different requirements for its vertical conveyors.
In Intelligrated's most recent On The Move webinar titled, "Vertical solutions: elevating your products to the next level," I discussed the available vertical conveyor options to meet these challenges. While the concept of vertical conveyance is relatively simple - moving product in a carton or tote to a different level in the warehouse - the variety of options to accomplish this can address varying degrees of process complexity. To select the best option for your operations, it's important to understand the pros and cons of each option.
As I presented in the webinar, vertical conveyors fall into four basic categories:
Continuous flow - Comprised of either incline or spiral options, continuous flow conveyors feature belt or motor-driven rollers and offer simple control systems. While incline conveyors provide high throughput rates, they are limited to single entry and exit points, and take up a lot of floor space. Similarly, spiral conveyors also provide high throughput rates and a relatively large footprint, but offer multiple entry and exit points.
Suspended shelf - As the name implies, suspended shelf conveyors employ a vertical shelf design to achieve multiple product elevations. Continuous suspended shelf options utilize a simple control system, provide single entry and exit points, offer medium throughput rates and still require medium to large space allotments.
Indexing suspended shelf - These servo-control systems have similar characteristics to suspended shelf conveyors while adding the benefits of multiple entry and exit points, and vertical merging and sorting.
Reciprocating conveyor - Vertical reciprocating conveyors (VRC) offer maximum flexibility in conveyor / shelving configurations and take up very little floor space. Also driven by a servo-control system, VRCs integrate with single-, double- or triple-zone conveyors; offer over- or under-conveyor configurations; and can be utilized in speciality zones such as transfers or turntables to deliver product to the most ergonomic position for workers. Since the shelf returns to the start position for product induction, VRCs operate at lower throughput rates. Regardless, the flexibility and small footprint of VRCs are making it an increasingly popular option.
Ultimately, selecting a vertical conveyor depends on your specific business objectives. To learn more about the possibilities of vertical conveyance and better understand which option is right for you, please view this webinar on our website.
Online shoppers are hungry for selection and speed. They want a strip mall worth of products at their fingertips, ready for delivery by their next meal. In fact, a recent survey shows that 87 percent of online shoppers identified shipping speed as a crucial factor in whether they were going to shop with a brand again, and 47 percent of those surveyed said they would pay more money to get same-day delivery.
The high volumes of smaller, individual orders flooding out of warehouses as a result of these e-commerce trends has spurred changes throughout distribution networks that have real consequences for material handling systems. For example, as carriers and shippers look to make the most efficient use of available delivery capacity, automated equipment must handle a wide range of packaging types - such as polybags.
How do I prepare for polybags?
To cut costs that come with dimensional weight pricing, more companies are using polybags or envelopes to ship individual e-commerce orders. For many omnichannel distribution centers, this means handling a variety of packaging types - polybags, corrugated boxes, totes - in one operating space.
Polybags, with their tendency to bunch up on themselves, bring a unique set of handling challenges. They need to move along a conveyor system with minimal contact and catchpoints to avoid jams and keep product moving. Motor driven roller (MDR) conveyor is the conveyor system of choice.
What are the advantages of MDR?
With the growing pressure to quickly ship items ranging in size from pill bottles to bed frames, the material handling industry is facing new challenges. To keep up with e-commerce order fulfillment, ask yourself: Are my conveyors ready for e-commerce? If you're using conventional conveyor systems designed to handle only cases or totes, the answer is probably no.
No matter the order size or packaging type, effective e-commerce order fulfillment requires moving high volumes of items through distribution processes quickly and efficiently - without damage. Zero-contact MDR technology enables individually-powered zones to instantly stop, maximizing product control, eliminating back pressure and reducing the risk of product damage.
This technology maximizes the amount of items on the conveyor, allowing operations to make the most of available space and optimize accumulation density. For e-commerce operations challenged to house an ever-expanding inventory, efficient use of space is critical, ultimately resulting in more orders fulfilled, greater customer satisfaction and a growing business.
MDR systems also use fewer conveyor parts, helping lower maintenance requirements and reducing the risk of downtime. Its modular design can scale as operational demand dictates and easily adapt to existing layouts and footprints for easy installation, along with providing the flexibility to change configurations as business needs (and online shopping patterns) shift.
But that's only part of the MDR story
The versatility of MDR conveyor means it is not just limited to e-commerce order fulfillment and polybag handling. An array of advanced features such as a full width belt, an array eye and more can take operations to the next level - to say nothing of MDR conveyor's essential role as part of sophisticated automated material handling solutions. Keep an eye out for these aspects and more in part two and three of Intelligrated's MDR conveyor blog series.

Modern DC operators face a common dilemma: the space they need to meet omnichannel demands is running out. As direct-to-consumer order fulfillment requirements continue to push the limits of service level expectations, the physical constraints of their warehouses have them feeling boxed in. Typical options to solve this problem - such as expansion, new facility construction or outsourcing - are often impractical and require significant capital expenditures. But there is another direction operators often overlook to maximize the use of their existing operations; upward!
Our next On The Move webinar will explore the vertical conveyor solutions available to solve the challenge of diminishing space in the DC. This complimentary webinar is titled, "Vertical solutions: elevating your products to the next level," and will take place on Thursday, March 23, 2 p.m. EDT / 11 a.m. PDT.

Think of conveyor as the streets and canals of the distribution center. Automated conveyor solutions are the essential infrastruture required to keep orders flowing to the right place at the right time. From pallet transport conveyor to case, tote and polybag varieties, each component - even down to conveyor parts and accessories - plays a critical role to meet operational requirements.
And just as city streets must accommodate motorcycles, cars, trucks, pedestrians and bicycles, every industry must accommodate more variety thanks to SKU proliferation. Big box retailers are expected to sell every brand of every product, from toothpaste to refrigerators. Every food and beverage distributor must offer year-round variety, seasonal specialites and health-conscious options. But besides product, packaging makes a difference, too. With the advent of dimensional weight pricing, most conveyor and transmission solutions must handle packaging types like polybags and bubble mailers that represent a significant departure from the rigid corrugate cases for which they were originally designed.
This places a premium on flexible conveyor solutions capable of fueling a facility's high-speed sorting procedure reliably and efficienctly. This means picking the right technology - conveyor belts and parts - matched to the requirements of the application.
And just like avoiding road closures and construction detours keeps traffic flowing, minimizing unplanned downtime and ensuring system availability is critical. This means a preventive maintenance program to head off issues before they happen and quick-response, 24X7 support in the event of an outage. Working with an OEM lifecycle management group and a computerized maintenance management system provides data-driven decisions and the necessary level of detail - even covering how to aggregate conveyor parts.

The increase in e-commerce home deliveries, combined with the advent of dimensional (or DIM) pricing in 2015 on some carrier ground deliveries, has translated to increased shipping costs associated with order fulfillment. As e-commerce continues to fuel the growth in small item home deliveries, last-mile carriers were quick to adopt this volumetric pricing strategy. To keep shipping costs low and ensure that web shoppers kept clicking the Submit Order button, retailers have since began the transition from traditional, corrugated cartons (boxes) to alternative shipping containers such as bubble mailers and polybags. In our most recent On The Move Webinar, “Goodbye cartons, hello polybags,” I explored the impacts this packaging shift has had on fulfillment strategies.
I kicked off the Webinar with a brief explanation of DIM pricing, including specific examples of how larger, yet lighter items are more expensive to ship than heavier, smaller products. I then shared two key statistics that demonstrated the impacts of this pricing change:
- 33 percent of all ground shipments are affected by DIM pricing
- Shipping costs increased 42 percent in 2015 compared to 2014
The first live Webinar poll question confirmed that 50 percent of attendees have already made changes to their organization to address the DIM pricing change. The second question revealed that 61 percent of attendees have already incorporated polybags into their packaging mix, with cartons still the most common packaging option at 93 percent. Clearly, there will always be a place for traditional packaging, but the pliable nature of polybags makes them ideal for irregular-shaped items or softer apparel-type products. But the rule of thumb with packaging is: the more pliable the packaging, the lower the DIM weight and shipping costs. Conversely, the more pliable the packaging, the more challenges it presents to the automated material handling system.
The remainder of the Webinar discussed the many ways retailers can lower shipping weights. Note that the first four items on this list precede addressing actual conveyance/sortation strategies:
- Re-negotiate with carriers
- Utilize on-demand packaging solutions via machines that create cartons based on order profile
- Install cartonization software that tells packers the optimal size package to use
- Deploy rate shopping software that selects the optimal carrier based on size, weight, destination and negotiated rates
- Perform pre-sortation at the fulfillment center to skip shipping zones and dramatically cut costs
- Reduce packaging sizes either with new systems designed to accommodate polybag flow from pack-out operations to shipping or by investigating opportunities to handle polybags with existing equipment
The two primary methods for incorporating polybags into fulfillment centers are singulated and bulk flow systems. I discussed the pros and cons of each method and explained that the bulk flow system eventually requires automated or manual singulation prior to final sortation in the fulfillment center.
I then explained some of the challenges associated with conveying polybags through the DC, including: the potential for extra catch points; the difficulty conveyor cameras have detecting the leading and trailing edges of an item; and the challenge of barcode identification due to package irregularities.
Finally, I addressed the variety of conveyor and sortation equipment types and their ability to handle these pliable polybags. There are a multitude of factors to consider and as many equipment options to evaluate, from rollers and belt zones to diverters and sweep sorters. With so many considerations, it’s vitally important for retailers to consult with an experienced material handling solution provider.
