Wedge Conveyors 101


In any warehouse or production facility, finding enough space for your conveyor systems can be a challenge. Wedge conveyors are flexible options that elevate your production flow, allowing you to reclaim valuable floor space in your facility.

In this article, we will explore wedge conveyor systems, including their benefits and possible applications.

What Is a Wedge Conveyor?

A wedge conveyor, also known as an elevator conveyor, is a specialized material handling system designed to move products between the production floor and other levels of your facility. They are most often found in distribution centers and warehouses and can be easily integrated with existing material handling systems because of their flexibility and ability to handle high-capacity projects. Wedge conveyors provide smooth, continuous transport of packages and products throughout your facility, making them an essential component in many material handling operations.

Benefits of Wedge Conveyors

Manufacturers can face many challenges, including the logistics of moving products around their facility. Vertical conveyors, including wedge conveyors, are a valuable tool in facilities where multiple elevations are used in production processes.

Wedge conveyors offer many benefits, including:

  • Easy to construct
  • Lightweight
  • Rapid transfer rate
  • Made from durable stainless steel or aluminum
  • Multiple configuration options
  • Meet strict hygiene standards for packaging lines

Wedge Conveyors

How Does a Wedge Conveyor Work?

Span Tech’s Wedge Conveyors are designed to provide vertical movement in a durable, compact and all-mechanical design. Products are fed from a horizontal conveyor belt onto the wedge conveyor with about one product length between them, allowing enough space for products to negotiate the curves. As an item reaches the wedge conveyor, two parallel conveyors use urethane gripper chains to wedge the sides of the product from either side. This action lifts or lowers it from the horizontal conveyor onto a receiving conveyor.

Our wedge conveyors with pressure relief can be operated at variable speed ranges and are available in a variety of chain types and widths to accommodate different sizes and shapes of products. There are no computers or logic/software components needed because the almost-silent vertical conveyor system is designed with all-mechanical movement, gripping products on their sides and sending them on their way. Depending on your facility’s needs, you can choose from the standard “positionable” or fully-adjustable wedge conveyor.

Applications for Wedge Conveyors

Because of their flexibility, wedge conveyors are perfect for use in a variety of applications including:

  1. Packaging
  2. Manufacturing
  3. Food & Beverage

Wedge conveyor systems are frequently used over walkways, under other conveyor lines, or to quickly change the orientation of a product or container (flip it over or face the opposing direction).

Guide to Metal Detection and How to Create a Metal-Free Zone

Conveyor Safety Standards


Product safety is a top priority in manufacturing, especially when it comes to food and pharmaceutical products. The right conveyor belt metal detector can give you the peace of mind that your line is safe and free from metal contamination.

In this article, we will look at the basics of metal detection on your conveyor line and how you can create a metal-free zone in your facility.

What Is Metal Contamination?

Metal contamination occurs when any pieces of metal make their way into a product during the manufacturing process. A conveyor metal detector is designed to alert you to any possible metal contaminants that make their way into your product.

There are three primary types of metallic contaminants:

  • Ferrous metals are easily detected, as they are both magnetic and conductive.
  • Non-ferrous metals are non-magnetic, but they are good conductors, so it is relatively easy to detect them.
  • Stainless steel is, for most grades, both non-magnetic and a poor conductor, making it difficult to detect.

Metal Detector Conveyors

What Is a Metal-Free Zone?

A metal-free zone is an area near the metal detector in your conveyor system where no metal is allowed. Metal detectors are constructed with high-frequency magnetic fields built into the device’s metal casing. In spite of this careful construction, it is still possible for the magnetic field to leak out of the detector’s aperture. Because of this, a metal-free zone must be created in the area surrounding the aperture.

If metal is placed too near the metal detector in the metal-free zone, the detector’s signal may spike, causing a false positive and unnecessarily disrupting your production.

How Can You Create a Metal-Free Zone in Your Facility?

To create a metal-free zone, you will need to do some calculations based on the type of metal being used and the aperture size of your conveyor belt metal detector. If the metal is non-moving, it should be at least 1.5 times the aperture height away from the opening; moving metal should be at least 2 times the height away from the opening.

What Should You Consider When Choosing Metal Detection Conveyor Products?

When you are choosing a metal detector for your conveyor system and establishing a metal-free zone, you want equipment that can do the job quickly, spot contamination in your system and provide options for product disposal. The three factors to consider are:

1. Aperture Size

Most apertures are 8 inches high by 14 inches wide, but customization is possible if necessary to meet your product specifications.

2. Sanitation

If sanitation measures are included in the conveyors, your employees will be able to quickly and easily clean the conveyor surfaces, observe products flagged as containing metal and remove them so your line can continue operating.

3. Reject Mechanisms

If metal is detected, reject mechanisms are necessary to prevent further contamination and quickly remove the product.

The three types of reject mechanisms available include:

  1. Push-on detect. When a metal detector flags a product, a pusher mechanism mounted to the side of the conveyor removes the product from the line for disposal.
  2. Air blast. A blast of air is used to remove rejected products from the line.
  3. Diverter arms. An arm swings across the conveyor belt to remove rejected products from the line.

Common Conveyor Belt Problems & How To Fix Them

Common Conveyor Belt Problems

With many conveyor systems running 24/7 in critical operations, common conveyor belt problems can cause serious trouble, leading to damaged equipment, unnecessary downtime and employee injuries.

Conveyor belt systems play a crucial role in today’s manufacturing and warehousing facilities, and it’s important to know how to keep them working properly, without the entire system breaking down.

With years of expertise across numerous industries, Span Tech has a comprehensive knowledge of conveyors. In this article, we’ll look at common conveyor problems and how to troubleshoot and prevent them.

6 Common Conveyor Belt Problems

The global conveyor market is expected to reach $10.6 billion by 2025. It’s a big business and one that touches a wide range of operations. Despite the market’s size, even small conveyor belt problems can have a domino effect, creating issues throughout a company’s system. The most common conveyor belt problems include:

  1. Conveyor Belt Tracking Problems
  2. Belt Slippage
  3. Blockages
  4. Carryback
  5. Material Spillage
  6. Seized Rollers

Here’s a closer look at each of these common conveyor belt issues.

Span Tech Conveyor Belt System

1. Conveyor Belt Tracking Problems

Conveyor belt tracking issues, often referred to as conveyor belt mistracking, are some of the most common conveyor problems. Belt mistracking occurs when the belt is no longer aligned with the proper path and pulls to one side or the other.

Possible causes of conveyor belt mistracking include belt damage, a crooked splice or off-center loading. There are also other areas of concern, such as:

  • A crooked or angled conveyor frame
  • Snub rollers that are out of alignment or not tensioned properly
  • Dirt or residue on the belt or pulleys, which can force the belt off track

If left undetected, mistracking can cause further belt damage and the shut down of the entire system.

To perform conveyor belt alignment troubleshooting, you should regularly inspect these areas and check for tell-tale signs of mistracking, like frayed edges on the belt. Keep the belt clean, repair damage as it arises and make sure loads are properly centered to avoid major issues and a long shut-down period.

2. Belt Slippage

Conveyor belt slippage is another of the most common conveyor belt problems. Conveyor belts require an exact balance of tension to operate correctly. Having too little or too much tension can cause belt slippage. Besides slippage, improper tension and insufficient traction also can create a strain or stretch on the belts, along with loud squealing and grating noises.

If the belt slips entirely off the pulleys, the result can be serious damage, like a motor failure.

While a range of issues can force a belt to slip, here are the most common causes:

  • Cold temperatures, which lower the grip between the pulleys and the belt
  • Overweight loads, which strain the belt, causing it to slip
  • Pulley issues, which can include a worn head pulley or pulleys that are too smooth

Lagging is often installed on pulleys to create the proper tension, but pulley lagging itself can cause belt slippage if the lagging is improperly implemented.

If you’re wondering how to make a belt stop slipping, the best defense is a good offense. Ensure your belt’s weight range matches the weight of the products you’re moving, and regularly inspect the belt and pulleys for the common causes of belt slippage. Repair these as soon as you find them.

3. Blockages

A conveyor belt line is supposed to transport products smoothly from one location to another. But sharp edges, corners and surfaces can snag an object, causing a pile-up as items begin to gather.

An unexpected accumulation of products can damage items and force the entire system to shut down.

To prevent blockages, regularly inspect your conveyor line for anything that could interfere with product movement and correct it promptly.

4. Carryback

Material carryback is a common conveyor belt problem for material handling systems that carry loose material. Carryback occurs when extra material sticks to the transporting belt, pulleys, idlers and rollers. Humidity and condensation can exacerbate the issue. Material caught like this requires extra cleanup and can lead to overly worn components.

One way to prevent carryback is to install belt cleaners or brushes that dislodge stuck material before it becomes an issue.

5. Material Spillage

It’s not uncommon for material to slide off a conveyor belt, particularly at points where loading and transferring occur. The lost material increases equipment wear and lowers productivity. It also presents a significant safety hazard since loose material can cause employees to slip or fall.

Some spillage is inevitable, but you can prevent excess material spillage by installing impact beds or skirt clamps. Since a poorly aligned conveyor system can increase the likelihood of spillage, it’s helpful to regularly check for and correct alignment issues.

6. Seized Rollers

Another common conveyor belt problem is seized rollers, which lead to sharp edges on the rollers that can:

  • Cause the belt to mistrack
  • Create a safety hazard
  • Damage the objects being transported
  • Close down the entire system

Regular inspections can help you identify rollers that are likely to seize, allowing you to replace them before issues arise.

How to Combat Common Conveyor Belt Problems

Common conveyor belt problems cause many issues, ranging from lost production to damaged products to employee injuries and shut-down operations. They often require time-consuming maintenance and repair operations to resolve the problems.

The most comprehensive approach to reducing common conveyor problems is to institute a regular preventive maintenance program. Preventive maintenance is a cost-effective way to catch conveyor problems when they’re easier to address and before they become major issues.

Of course, it’s always important to follow all the best safety advice when working on conveyors, including proper lock-out/tag-out procedures, which ensure that the power is turned off on the equipment you’re repairing.

Guide to Conveyor Belt Tracking

Conveyor Belt Tracking

If your business relies on conveyor belts, you want them to be up and running when you need them. One of the most important factors to keeping a conveyor belt running properly is conveyor belt tracking.

Mis-tracking conveyor belts means downtime for your conveyor systems, and no matter what industry you are in, downtime means lost money. This article will look at what tracking is, how to track a conveyor belt and how to fix issues that can impact the proper tracking of a belt.

What Is Conveyor Belt Tracking?

Conveyor belt tracking is the process of aligning and controlling a conveyor belt so that it follows the desired path. Tracking is a process of adjusting idlers, pulleys and loading conditions to adjust and fix any tendency of the belt to run any way other than intended.

How to Track a Conveyor Belt

Conveyor belt tracking is important but it doesn’t have to be complicated. Here are three easy steps for tracking a conveyor belt.

  1. While the conveyor is operating, loosen the bolts closest to the tail pulley. That will loosen the primary method of steering the conveyor belt, the snub roller.
  2. Using a rubber mallet, gently tap the bolts in whatever direction you want the conveyor belt to move. This will cause the snub roller to move. After the snub roller has been adjusted, be sure to re-tighten the bolts so it will be locked into the new position.
  3. Steps 1 and 2 should be repeated until the center of your conveyor belt is within a quarter inch of the tail pulley’s center. Be careful not to make any large adjustments. A small adjustment can make a huge change. Make sure to start with the snub rollers closest to the ends of the conveyor and work your way towards the center.
Conveyor Tracking

How to Fix Conveyor Belt Tracking

When tracking conveyor belts, there are steps you can take to maintain your conveyor belts as well as steps you should take when there are issues with conveyor tracking. The following tips are things to watch for if you are having trouble with conveyor belt alignment.

Make Sure The Conveyor Frame Is Level and Square

A large percentage of conveyor belt tracking issues are caused by the track being out of level or square. If your conveyor is out of level or square, the belt will move to one side or the other.

Using a standard level, you can quickly check your conveyor system’s levelness. It’s important to check both the pulleys and the frames for levelness. To check that your conveyor bed is square, snap dimensions from one corner to the opposite corner on each side of the conveyor belt. The measurements should be equal. If they are not, squaring rods on the bottom of the conveyor can be used to pull the frame into alignment.

Confirm the End Pulleys Are Square

Sometimes conveyor belt installers will steer the end pulley to track the conveyor belt. Unfortunately, this can make the problem worse. Instead, use the snub rollers or idlers to track the belt, as intended.

Check for Any Debris in Your System

It’s important to inspect conveyor belts for not just mechanical issues, but also cleanliness. If tape or other debris builds up on one or both of the end pulleys, it can lead to a crown or a raised portion on the pulley. This will result in problems with conveyor belt tracking.

Ensure Your Conveyor Belt Has Been Cut Straight

Problems with your conveyor tracking may be a result of manufacturing defects. During the manufacturing process, the belts can be cut improperly leaving a curvature or arc. If you have reason to think this may be the problem, remove the belt and lay it out flat to see if it looks straight.

Because there are very few limitations to designing injection molded parts, modern engineering methods allow them to be designed to optimize strength and thus are surprisingly durable. Molded plastic conveyor parts are designed to handle the most rigorous loading for the application.

More Consistency

Welded metal parts often have issues with warping, which is oftentimes unpredictable and can be hard to control. Molded plastic conveyor belt parts are more uniform than their metal counterparts.

Less QC is Required

Manufactured parts often have to go through several steps during the manufacturing process (such as sawing, milling, turning, welding, coating, etc.). When replacing parts that are coated (like an LPI chain guide), there’s less chance of losing parts due to additional steps in manufacturing, so less quality checking is required.

Improved Material Characteristics

Plastics come in a wide range of material properties. Parts can be made rigid or flexible, high-friction or low-friction. Depending on the design requirements, there’s a plastic material that’s best suited for the application.

Better Design

Molded plastic parts can be engineered with features that are much more ergonomic and safe compared to traditionally manufactured metal parts.

Types of Molded Plastic Parts on a Conveyor Belt

  • Liners
  • Bins

Frequently Asked Questions About Custom-Molded Plastic Conveyor Belt Parts

Because they are such a departure from traditional metal and rubber components, people frequently have questions about custom-molded plastic conveyor belt parts.

What Are the Parts of a Conveyor System?

A conveyor system has three main components:

  • Belt Guides: This keeps the belt taut and moving smoothly and efficiently.
  • Pulleys/Sprockets: Conveyor systems have at least two pulleys – one that operates when the unit is powered up, the other when it’s idling. Pulleys control the conveyor belt’s movement.
  • Drive Unit: This enables the system to move efficiently, forward and backward.

What Is a Modular Conveyor System?

A modular belt conveyor contains plastic modules that link together with rods. Sprockets drive the modular belt. Unlike most fabric/plastic belts, modular belts can be made to be pulled through curves and vertical bends. Also, fabric/plastic belts require a tensioning system – modular plastic belts do not. And because they’re more rugged, plastic modular belts are especially useful for moving hot workpieces or items with sharp edges. Chain modules are permeable to air, making modular conveyor equipment the best choice for cooling lines. And due to its simpler design, a modular conveyor system has the added benefit of easy maintenance.

What Is a Plastic Modular Belt?

Modular plastic belting is an alternative to traditional fabric conveyor belt systems. It’s positive-driven, has low tension and eliminates slippage on drives. A plastic modular belt is also durable and simple to maintain, making it ideal for applications in nearly every major industry.
