Stainless Steel Belts for Automated Dairy Farm Robotics Application

Recently, we were approached by an OEM producing automated robotic equipment for the dairy industry. The client came to the metal belt experts to troubleshoot an issue they were having with the metal bands in their robotic milking arms. 

Stainless Steel Timing Belts, Drive Tapes & Attachments for Robotics Applications

There are many benefits to choosing stainless steel timing belts and drive tapes for robotics applications. They have a high strength-to-weight ratio, are virtually non-stretchable, do not require lubrication, and can operate with near zero backlash for maximum, repeatable accuracy. Belt Technologies has produced metal drive tapes for numerous robotics applications including medical and pharmaceutical applications, packaging, industrial automation, and robotic arm actuators. 

All of our metal drive tapes and timing belts are fabricated using the same high-quality stainless steel materials as our endless metal conveyor belts. Drive tapes and timing belts can also be specialized as required with custom perforation patterns, locating pins, end tabs, and attachments. They are ideal for maintaining positional accuracy throughout the operational lifespan of your equipment.

Engineering & Design Service Support

The customer’s equipment included a robotic arm that was approximately 3ft long with 18in joints which controlled milking attachments designed to gently connect to the cow’s udders using a visually guided system. The attachments milked the cow and sent the dairy product through a processing system where it would be tested to affirm the health of the animals and assess the quality before moving on to pasteurization. 

The automated milking system was designed to support a large industrial dairy farm that could hold up to 1,200 cows or more. It would need to be highly durable as well as accurate in order to sustain operations at that scale. Unfortunately, a metal band component that moved the arm of the machine was experiencing a high rate of failure due to poor attachment points and high torque. Belt Technologies was able to provide the client with engineering & design services to redesign the assembly to remove high bending loads and perform a stress optimization analysis to reduce overall stresses to extend belt life.

How to Achieve the Maximum Metal Belt Conveyor Lifespan

To get the most out of your metal belts, there are a few design considerations to keep in mind; these will help prevent unnecessary wear and tear and ensure that your belts have the longest lives possible.

Design Considerations to Keep in Mind Before You Install

The most unexpected difference between metal belts and conventional conveyor belt types is the ratio between pulley diameter and belt thickness that must be maintained. While metal belts are typically made of stainless steel, pulleys can be manufactured from stainless steel, aluminum, or plastic, depending on the design specifications. Most metal belt pulleys are either round stock, I-beam, or capped tube and can be designed with drive lug timing pockets, relief channels, conventional timing teeth, or Belt Technologies’ patented ball bearing timing teeth. For metal belts to perform as well as they can, it is imperative to use the largest possible pulley diameter in relation to the thickness of the belt. The minimum ratio that we recommend at Belt Technologies is a strictly maintained 625:1.

Reverse bends in metal belts should be avoided unless absolutely necessary, as they will compromise the lifespan of the belts. Along the same lines, there should be as few pulleys as possible included in the conveyor system to limit unnecessary stress on the belt.

Handle with Care

Although metal belts provide a higher resistance to temperature, chemical corrosion, and physical damage, they must be handled carefully during installation; particularly in the case of thinner metal belts. Damage can occur at the edges and at the weld joint of the belts during installation and maintenance.

The tension of the belt is another factor that can contribute to the lifespan of a belt. Belt tension should be kept as low as possible to improve belt life and reduce wear on the system. When tension is too high, the system frame can warp or the belt itself may fracture. Our engineers can help by providing guidelines to determine the right belt tension.

Keep It Clean

Metal belt conveyor systems should be designed with easy access to one side of the system. This reduces downtime during maintenance and sanitization procedures by making it easier to access the inner workings of the metal belt conveyor system. To prevent excessive damage to the belt, the interior and exterior diameter of the belt should be kept free of debris as much as possible.

By following these guidelines during the design phase of your metal belt conveyor system, you will maximize the lifespan of your stainless steel belt. Regular maintenance and proper cleaning should be part of your routine operations once the belt is installed. These measures will maximize the lifespan of the belt and reduce the chance of excessive damage from debris or misuse.

Our engineers have over 50 years of experience in designing, manufacturing, and installing endless metal belt conveyor systems. While every one of our customers and every one of our projects is unique, there are some common factors that affect every metal belt conveyor system design. Our team put together a few of the most important points to consider before upgrading to an endless metal belt; the following should help give you an idea of what to expect from the design process.

Define the Application and Conveyor System Requirements

It’s important to understand the unique requirements of your application. Typically, customers approach us for a metal belt because they need to:

  • Solve a problem with their current automated conveyor system.
  • Develop a new product
  • Increase manufacturing speed
  • Improve end product quality

Our engineers will work with you to determine which elements of your manufacturing process are relevant to the end design of your new, endless metal belt conveyor system. They will take into consideration factors such as available space, desired processing speed, special material handling needs, and sanitation requirements of the overall system.

Collaboration with you is a key part of our manufacturing and design process. We make it a priority to keep you informed to ensure the end result is a metal belt conveyor system that meets and exceeds your expectations for performance.

Understand the Unique Capabilities of Stainless Steel Belts

There is a long list of reasons why metal belts are a superior automated conveyor system design option. Metal belts are able to perform in environments that standard metal belts simply cannot. Stainless steel metal belts are more resistant to extreme temperatures and potential damage that may be caused by friction or sharp objects. The unique properties of metal belts make them ideal for use in clean rooms or vacuum environments. They will not transmit particulates and they discharge static electricity, making them an excellent choice for a manufacture of electronics.

Design Considerations That Will Maximize the Lifespan of Your Belt

You can easily maximize the lifespan of your metal belt conveyor system when the initial design incorporates elements that will prevent unnecessary wear and tear. Metal belts require a certain pulley diameter based on belt thickness; to maximize belt life use the largest possible pulley diameter and keep the ratio between pulley diameter and belt thickness at 625:1 or greater. The number of pulleys included in the system should be kept to a minimum (fig. 1a) and reverse bends (fig. 1b) should be avoided whenever possible.

It is also important to apply the proper tension to the belt without over-tensioning or causing the frame to bow. Our engineers can provide you with specific guidelines for the type and style of metal belt you will be using.

Choose the Best Material for Your Automated Manufacturing Application

Our metal belts are made of stainless steel for long-lasting, durable operation. Depending on your system’s needs, pulleys may be made from stainless steel, aluminum, or plastic. There is a wide variety of surface coating options available to further specialize your metal belt to suit your specific needs. Some of the available coating options include:

  • Non-stick TeflonⓇ
  • GATORCOATⓇ
  • Urethane or neoprene
  • Silicone

Belt Technologies, Inc. is able to apply a wide range of additional surface treatments, from fluorocarbon compounds to gold plating and powdered diamond bonding. Perforations can easily be implemented to metal belt designs. Precision perforations are made mechanically or with other non-impact methods for timing, carriage positions, indexing, or vacuum conveying purposes.
