Utilizing a Vacuum Pump for Automated Material Handling with Robots

From electronics to logistics, packaging, food processing, printing, paper, construction, and more, robotic material handling stands out as the swiftest, most precise, and efficient method for moving materials.

Every manufacturing process requires careful consideration when it comes to material handling. Alongside selecting the right industrial robots and software programming, choosing the appropriate gripping technology to handle specific packages or products is crucial.

While physical handling by human employees is the simplest method for picking and placing objects, alternative options include automated robotic handling using vacuum pumps, mechanical grippers, or Venturi pumps that utilize compressed air to create a vacuum.

This article focuses on the selection of the correct vacuum pump for automated robotic material handling applications.

Vacuum Pumps for Robotic Material Handling

The fundamental process of robotic handling utilizes a vacuum pump to create vacuum pressure, which temporarily holds an item using an end-of-arm tool (EOAT) for movement or modification. The most common application is placing products in boxes or moving the boxes themselves. However, pick-and-place methods can also be used for accurately positioning small electronic components on circuit boards or relocating heavy concrete blocks in construction projects.

This process involves connecting the vacuum pump to tubes or piping, which are then linked to EOATs like vacuum cups that pick up, hold, and release products at the desired location.

Challenges in Material Handling

When selecting a handling method, several challenges must be addressed. Human employees have limited productivity levels and may face high labor costs. They can also be at risk of injury from heavy loads or exposure to hazardous materials in the manufacturing environment.

Mechanical gripping, although an option, can be slower and may require high gripping strength, potentially damaging delicate items. Furthermore, hazards from products or manufacturing processes can harm mechanical handling equipment, especially when dealing with corrosive chemicals.

Vacuum Pumps: An Effective Solution

Robotic applications using vacuum technology simplify the process of picking and placing objects, making it faster, safer, and less physically demanding for employees. Vacuum pumps are often a safer choice compared to mechanical handling, particularly in hazardous environments or when handling dangerous materials.

There are two main types of pumps used in automated robotic material handling systems: mechanical vacuum pumps and Venturi pumps.

While Venturi pumps may have a lower initial cost, they require access to a compressed air source, resulting in higher overall costs due to increased energy consumption and lower efficiency compared to mechanical vacuum pumps.

Mechanical vacuum pumps provide the necessary vacuum for grasping, holding, positioning, and moving objects. Compact pumps can be positioned near the assembly line and robot, requiring only short tubes or pipes to supply the necessary vacuum flow to the robot's EOAT.

Selecting a Vacuum Pump for Robotic Material Handling

Different types of vacuum pumps, such as dry rotary vane, hook and claw, regenerative blower, and oil-lubricated pumps, offer specific benefits for various applications in robotic material handling.

Considerations such as the type of product, required action and accuracy, product surface material, weight, porosity, available gripping surface, type of gripping tool (EOAT), and machine movement speed/force are crucial in choosing the right vacuum pump. Consulting with experts can ensure the selection of the most effective and efficient vacuum solution for specific needs.

The Most Valuable Feature of High-Quality Vacuum Pumps

While you expect most quality vacuum pumps to offer performance, reliability, and ease of use right out of the box, you won’t find the most valuable feature of leading brand pump equipment listed on a spec sheet.

That’s because only the leading vacuum pump manufacturers deliver superior post-sale technical support and customer service as standard on every pump they sell.

Below we take a look at what it takes to deliver long-term support of vacuum pump equipment supplied to an OEM or end user.

We’ll consider why just a select few companies are able to add this valuable “extra feature” to every pump they ship when so many others fall by the wayside.

ARE YOU GETTING SERVICE WITH A SELL-BY DATE?

If you’re a manufacturer or user of secondary packaging equipment, the vacuum pumps powering your application are not just standalone gear that can be installed, operated, and maintained in isolation from the rest of your line.

They’re mission-critical pieces of equipment with physical footprints, power ratings, and pump-down curves that are optimized for your process and product.

Why then do so many industrial suppliers try to sell you an off-the-shelf vacuum pump product promising good-enough performance and little to no support if things don’t pan out?

ONE SIZE FITS NONE

One size fits all might work well for a baseball cap, but it’s a bad fit for any at-scale precision manufacturing process. If you’re packaging in bulk, minor efficiencies will quickly add up to expensive overruns or maintenance headaches.

Despite this, many equipment makers rely heavily on independent distribution networks to place standard equipment with customers. 

This approach depends heavily on the knowledge and dedication of the distributor and makes it difficult to optimize equipment to your needs, especially if you are an end-user looking to design or upgrade a line. 

TROUBLE DOWN THE LINE

If you’re being offered a “convenient” off-the-shelf solution for your particular production challenge by a supplier or distributor, it makes sense to ask how much skin your supplier really has in the game, and what you can expect when the sale is done and the equipment has been delivered. 

It also makes sense to consider whether any money you save on the deal now is going to translate into long-term value if you are going to struggle to find parts or need to invest in expensive third-party support down the line.

If you are an OEM evaluating a unit for your products, it’s important to consider whether your equipment supplier has the capacity to continue to produce and support their product for years to come, or if you are going to be left scrambling for parts or trying to retrofit existing equipment.

ARE YOU BEING SERVED, OR SOLD?

While you will usually receive plenty of attention from salespeople if you are in the market for pumps for existing or new-to-the-market equipment, in many cases that interest declines significantly once you’ve agreed to buy.

Failing to check out what after-sale service you might receive before agreeing to a deal can put you in a difficult position months or even years after the sale, potentially leaving you with:

• Pumps that are poorly suited to or even incompatible with your equipment

• No technical support or troubleshooting

• Difficulting sourcing replacement parts

• Difficulty finding trained service personal

• Difficulty getting pumps repaired or overhauled

In a worst-case scenario, you could be left with equipment that is no longer even manufactured, or is made overseas but not supported by local dealers.

7 KEY QUESTIONS TO ASK YOUR SUPPLIER

It can be difficult to know if a supplier can provide good quality products and support services that will help you meet your goals and add value to your operation in the long run. 

Here are some important questions to ask before you commit to buying a new vacuum pump: 

1. Is your supplier the original manufacturer or a licensed or independent dealer?

2. Is the supplier available to answer questions during the sale process?

3. Is your supplier offering standard products or can they be customized?

4. Has a manufacturer’s representative visited your plant?

5. Does your supplier support both OEMs and end users?

6. Does your supplier support their own products or outsource this to a third party?

7. Does your supplier offer installation support, maintenance services, or on-site repairs?

Your answers should give you some idea as to whether your supplier has the knowledge, experience, and market clout to guide you through the sales process, supply you with the quality products you need, and support your equipment in the long run.

How to Use a Vacuum Pump for Robotic Material Handling

Whether it’s electronics, logistics, packaging & food processing, printing & paper, construction, or another production process, robotic material handling can be the fastest, most accurate, and most efficient method of picking and placing materials.

Every manufacturing process has its requirements for handling materials. In addition to selecting industrial robots and software programming, choosing the right technology for gripping and holding the specific package or product is critical.

The simplest solution for picking and placing objects is physical handling by human employees. Alternative choices include using vacuum pumps for automated robotic handling, mechanical grippers, or Venturi pumps (using compressed air to create vacuum).

In this article, we focus on selecting the right vacuum pump for automated robotic material handling applications. 

VACUUM PUMPS FOR ROBOTIC MATERIAL HANDLING 

The basic process of robotic handling uses vacuum created by a vacuum pump to temporarily hold an item with an end-of-arm tool (EOAT) to move or modify it. The most common application is placing a product in a box and/or moving the box itself. But pick & place also can be used to accurately place tiny electronic elements on a circuit board or move heavy concrete blocks for construction.

Moving an object this way requires the vacuum pump to be hooked to tubes or piping which are connected to EOATs such as vacuum cups that pick up and hold the product, then release it in the correct location. 

MATERIAL HANDLING CHALLENGES

However, there are challenges to handling materials that must be addressed when selecting the method to use. For example, human employees are limited in the amount of work each can accomplish in a day, and the payroll cost can be high. Employees may also be susceptible to injury from heavy loads or exposure to hazardous materials, processes, or equipment.

Mechanical gripping is slower and sometimes a high gripping strength is needed, which can damage sensitive or delicate items. Hazards from the product or the manufacturing environment, such as corrosive chemicals also may damage any mechanical handling equipment.

VACUUM PUMPS: AN EFFECTIVE SOLUTION 

Robotic applications using vacuum make picking and placing objects easier, faster, and often safer, with less physical work for employees. Vacuum pumps typically are a safer alternative to mechanical or physical handling, especially in hazardous locations or when dealing with hazardous materials.

Two types of pumps can supply vacuum to an automated robotic material handling system: mechanical vacuum pumps and Venturi pumps.

While Venturi pumps may cost less upfront, they require access to a compressed air source, making them overall more costly with higher energy consumption and lower efficiency than mechanical vacuum pumps.

Mechanical vacuum pumps provide the vacuum source needed to grasp, hold, position, and/or move an object. Compact pumps can be located quite close to the assembly line and robot so that only a short tube or pipe is needed to supply the robot’s EOAT with the necessary vacuum flow. 

CHOOSING A VACUUM PUMP FOR ROBOTIC MATERIAL HANDLING 

Dry rotary vane, hook and claw, regenerative blower, and oil-lubricated vacuum pumps all have traits that are needed for specific applications in robotic material handling. 

Oil-lubricated pumps typically are not used in the most common robotic material handling applications due to potential contamination from oil mist exhaust from the pump. But oil-lubricated pumps are ideal for moving moist or oily products and dense materials like glass or sheet metal with small suction cups.

REQUIRED PRODUCT SPECIFICATIONS

To determine the right vacuum pump type and model for a particular material handling application, the following factors are critical:

• Type of product to be moved

• Required action and accuracy

• Product surface material

• Product weight

• Product porosity

• Available gripping surface

• Type of gripping tool (EOAT)

• Speed/force of machine movement

Each of these factors should be discussed in detail with the Becker team to ensure that the most effective and efficient vacuum solution is recommended for your needs. We offer several pump types and models appropriate for automated systems handling a range of materials in a robotic pick and place system.

What You Need to Know about Progressing Cavity Pumps

How are progressing cavity pumps constructed? What advantages and disadvantages do they have? How do progressing cavity pumps work? For which applications are they particularly suitable? NETZSCH Pumps & Systems, the world market leader in the field of progressing cavity pumps, has the answers to your questions.

We can draw on more than 70 years of expertise in developing, producing and distributing progressing cavity pumps worldwide. Everything you need to know about this proven technology can be found here.

Construction of progressing cavity pumps

Progressing cavity pumps are suitable for efficiently pumping a wide variety of media. Due to their inventor, René Moineau, they are also known by other names such as Moineau pumps, Mohno pumps, Moyno pumps or mono pumps and consist of several components. The main components of progressive cavity pumps at a glance:

• Rotor

• Stator

• Pump housing

• Inlet and outlet openings

• Drive unit

The rotor is the central moving component of the pump. It has an eccentric arrangement in the pump housing. The rotor can be described as a feeding screw or spiral. The second elementary component of progressing cavity pumps is the stator. It is the stationary, elastic housing that encloses the rotor. The stator has a unique internal geometry corresponding to the rotor's external form. It is often made of rubber-like materials to ensure a tight seal between the rotor and stator. The pump housing, on the other hand, is usually made of metal. It is the outer frame of the pump enclosing the stator. It contains the stator and allows the pumped liquid to enter and exit. In addition, progressing cavity pumps, like all other pumps, have inlet and outlet openings through which the fluid enters and exits the pump. Another component is the drive unit that moves the rotor. This can be an electric motor, a hydraulic motor or other drive mechanisms.

Function of progressing cavity pumps

Progressing cavity pumps work on the positive displacement principle, in which an eccentrically rotating rotor forms a progressive cavity within an elastic stator. In the inlet phase, the pumped medium is sucked into this cavity. During the pumping process, the rotor pushes the medium in front of it as it rotates, transporting it continuously and precisely from the inlet to the outlet opening. The precise fit between the rotor and stator ensures a tight seal and enables viscous, abrasive media to be pumped efficiently with low pulsation and without damaging the pump.

Advantages of progressing cavity pumps

Progressing cavity pumps offer several advantages, making them attractive for various industrial applications. Thanks to the principle of positive displacement, progressing cavity pumps can be used to pump a wide range of viscous media, slurries, and suspensions gently and precisely. Their low degree of pulsation minimises wear on pump components and, at the same time, enables you to achieve consistent pumping. The tight fit between the rotor and the stator ensures efficient sealing, minimising pressure loss. You can also use progressing cavity pumps to pump sensitive media without damage. Their versatility, high efficiency and easy maintenance make them a favourite choice in various industries and applications.

Disadvantages of progressing cavity pumps

Despite their advantages, progressing cavity pumps also have some potential disadvantages. Due to their positive displacement, they can be sensitive to dry running if not sufficiently lubricated, leading to increased wear. Another factor is the limited pumping speed compared to other pump types such as multi screw pumps, which can make them difficult to adapt to high flow rate applications. In addition, certain media require unique materials for the rotor and stator to minimise corrosion and abrasion. The complex geometry of the pump can also make cleaning and maintenance more difficult. Despite these aspects, the disadvantages compared to the advantages are often highly dependent on the specific application, and many of these challenges can be minimised through careful selection, installation and maintenance. Our experts are on hand to advise and support you in choosing the right technology. And our service and support do not end with the purchase. From advice, maintenance and spare parts to repairing and modernising your pump, we are at your side. Thanks to our worldwide service network, we are ready for you around the clock in an emergency.

8 Symptoms of Underperforming Secondary Packaging Pumps

Strange noises, slipping production, and inconsistent suction can all be signs a vacuum pump is not keeping up with the demands of a secondary packaging application.

We take a look at eight telltale signs that indicate a secondary packaging pump is underperforming and what you, as a packaging equipment supplier or end user, can do about it.

In many cases, timely maintenance or a factory repair by the manufacturer can fix the problem. In others, it might be time for a conversation about a replacement pump better suited to the demands of your application and production schedule. Read on to learn how to spot equipment that’s falling behind.

FLAGGING PUMP TROUBLE: 8 TELLTALE SIGNS

If you’re an end user or OEM relying on vacuum pumps for secondary packaging applications from tray forming to palletizing, then you know how important strong, consistent vacuum pressure is to maintain production and ensure the final quality of your product.

Problems with a vacuum pump may start small but can begin to affect the efficiency of your line before you know it, especially if you’re not using equipment designed specifically for the needs of your application.

Here are eight symptoms to look out for that might indicate an underperforming secondary vacuum pump.

1. INCREASED OR UNUSUAL NOISE

Changes in the amount or type of noise a vacuum pump produces can be the first indication of trouble—indicating wear, internal damage, or another malfunction.

2. VACUUM FLUCTUATIONS

Falling or inconsistent vacuum will immediately affect your operation. Slipping or misaligned cartons, improperly formed trays, or dropped boxes are just some signs that a pump vacuum could be low or fluctuating.

3. LOWER PRODUCTION

Slowing operation or unexpected downtime can indicate a pump that’s struggling to maintain the required suction pressure. At this point, pump problems are already directly affecting your production, so it’s time to take action.

4. INCREASED ENERGY CONSUMPTION

Vacuum pumps are major drivers of operating costs. Spiking consumption may be the first indication that a unit is struggling to do its job. Act now to keep energy overheads under control.

5. OVERHEATING

A pump running hotter than usual is a classic sign of internal stress. It’s also a serious safety hazard. The longer you let an overheating pump run, the greater the chance of serious damage or a complete pump failure.

6. LONGER PUMP-DOWN TIMES

Rapid pump-down times are a key performance variable for hard-working secondary packaging pumps. While cheaper pumps generally have longer pump-down times, if your unit is taking longer to reach working pressure after a restart, you may have a problem.

7. INCREASED OIL MIST

Quality oil-flooded pumps should produce little or no “oil mist “ when operating. Excessive oil mist may be a sign of increased internal heat and pressure. Take action to remedy the problem and prevent further contamination of your work area.

8. INCREASED MAINTENANCE

If a pump starts to burn through replacement parts like filters, separators, or gaskets faster than it should, it may indicate an underlying problem. Keeping an eye on recommended maintenance intervals might help you flag potential problems early.

COMMON CAUSES OF PUMP UNDERPERFORMANCE

Multiple symptoms often point to just a few causes of pump stress. These can include both maintenance and design issues, as well as problems with your line setup or design. Here are some of the common causes of secondary packaging vacuum pump underperformance.

MISSED MAINTENANCE

Skipping or delaying scheduled maintenance checks can lead to wear and tear that goes unnoticed until it becomes a bigger issue. Clogged internal air filters and oil separators can allow a unit to overheat, damaging pump vanes and bearings and potentially leading to a pump failure.

DUSTY ENVIRONMENTS

Atmospheric dust from bulk food products or packaging fibers is common in food packaging environments and poses a particular threat to pumps if filters are not maintained. 

Accumulated dust can damage the vanes in rotary vacuum pumps and clog oil lines in flooded units, causing overheating, wear, and inefficiency.

IMPROPER CLEANING

Inappropriate cleaning methods or materials, such as using water without proper protection, can also introduce contaminants into the pump and lead to malfunctions. This is a particular risk in food packaging plants that need to be kept sanitary.

INCORRECT PUMP CAPACITY

Choosing a pump with either too much or too little capacity for the job can lead to inefficiency and wear, thereby increasing maintenance needs and reducing equipment life. It’s crucial to work with your pump’s manufacturer to match its capacity with the needs of your packaging application.

INCORRECT PUMP DESIGN

Pump performance needs to be matched to the unique needs of your application. Using an off-the-shelf pump that is not designed for your specific operation can also lead to early wear, reduced performance, and increased maintenance.

The best equipment suppliers work closely with pump manufacturers to match equipment specs to the demands of a particular process.

INCORRECT PLUMBING SIZING

If the piping or tubing connected to the pump is not correctly sized, it can restrict flow or create unnecessary resistance, diminishing the pump’s effectiveness while increasing wear and potentially causing long-term damage to your equipment. 

Pump equipment needs to be integrated with the correct inlet size to ensure an effective and efficient vacuum across the entire connected system.

POOR QUALITY EQUIPMENT

There’s no substitute for professional-grade, purpose-designed equipment. Opting for cheaper, off-the-shelf equipment might seem like a short-term win, but can cost you more in maintenance, downtime, and equipment overhauls in the long run.

If you’re committed to delivering safe, efficient secondary packaging at scale, you need reliable, industrial-grade vacuum pumps designed for the task at hand.

PUMP UNDERPERFORMANCE: WHAT YOU CAN DO

Here’s what you can do to prevent a pump from failing prematurely or to get equipment that is already underperforming back to peak condition.

1. STICK TO MANDATED MAINTENANCE SCHEDULES

Consult your manuals or check with the manufacturer about the ideal maintenance intervals for your equipment. Or even better, sign up for a scheduled maintenance service. 

Make sure filters, separators, and oil are all changed as required and check that your pump’s gaskets and vanes are in good condition. Some manufacturers even supply ready-packaged maintenance and repair kits to make upkeep as easy as possible.

2. VANE REPLACEMENT

Where damage to your pump’s vanes has already occurred and is affecting performance, replacing these vanes can be cheaper than replacing or rebuilding a unit and should restore your machine to optimum performance.

Higher-quality units are generally easier to service in this way and reputable manufacturers are more likely to have original replacement parts available years or even decades after your pump was installed.

3. FACTORY REPAIRS 

Where bearings or the electric motor itself have been damaged due to contamination or a lack of maintenance, it may be necessary to rebuild the entire pump. While this may be necessary to extend the life of a unit, it might be more cost-effective to replace some older or cheaper pumps.

On the other hand, leading equipment manufacturers including Becker offer vacuum pump overhauls and rebuilds at their facilities by their own trained technicians.

4. PUMP REPLACEMENT

Where a unit has been irretrievably damaged, has become too inefficient, or is just unsuitable for the application it was being used for, it may become necessary to replace the unit.

You can invest in the long-term efficiency and profitability of equipment by ensuring the replacement pump is up to the job. Choose high-quality equipment that’s designed for your application and is backed up by after-sale service and support from a reputable supplier.

5. PLANT-WIDE AUDITS

Where a pump is experiencing repeated problems or more than one pump unit is failing, it might help to have experts from your pump manufacturer visit your plant. Companies like Becker can help you pinpoint plant-wide problems like dust or inadequate plumbing. They can also predict, prevent, and mitigate continuing pump underperformance.

How To Prevent Cavitation In Centrifugal Pumps

Centrifugal pumps play a crucial role in various industries, yet they are susceptible to cavitation, a damaging phenomenon that reduces efficiency and harms the pump's components. This article explores preventive measures to safeguard centrifugal pumps from cavitation, covering factors influencing cavitation, its symptoms, detection tools, case studies, and advancements in prevention techniques.

Understanding Cavitation

Cavitation arises when liquid pressure falls below its vapor pressure, leading to the formation and collapse of vapor bubbles within the pump. This process can occur in different pump sections like the impeller, volute, or suction pipe. Factors such as pump design, operational conditions, and liquid properties contribute to cavitation, impacting pump efficiency and longevity.

Symptoms of Cavitation in Centrifugal Pumps

Recognizable signs of cavitation include unusual noises like rattling or clicking, vibrations felt in the pump or connected piping, reduced liquid flow, lowered pressure output, damage to pump components over time, and overheating due to energy conversion from collapsing bubbles.

Prevention Strategies for Cavitation

To prevent cavitation effectively, several strategies can be employed:

1. Ensure proper suction conditions: Maintain optimal inlet pressure, straight suction lines, appropriate sizing, and clean strainers to prevent blockages.

2. Optimize impeller design: Design impellers for uniform flow, avoiding turbulence and pressure drops.

3. Control fluid temperature: Keep fluid temperatures within recommended ranges to avoid vapor pressure changes.

4. Use a NPSH margin: Maintain a positive suction head margin to prevent cavitation onset.

5. Check for leaks: Regularly inspect and repair leaks to prevent air entry and subsequent cavitation.

6. Use appropriate materials: Select materials resistant to cavitation to enhance pump durability.

7. Regular maintenance: Conduct routine checks, lubricate components, and ensure proper alignment to mitigate cavitation risks.

Detecting Cavitation in Pumps

Various detection methods exist, including visual inspection for component damage, vibration analysis for abnormal pump vibrations, acoustic analysis to detect collapsing bubble noise, pressure sensors to monitor pressure drops, temperature sensors for detecting temperature changes, flow visualization techniques, and thermal imaging to observe temperature fluctuations.

Understanding cavitation and employing preventive measures are crucial for maintaining centrifugal pump efficiency and longevity. Utilizing optimal pump designs, monitoring conditions, conducting regular maintenance, and leveraging technological advancements can significantly reduce cavitation risks and improve overall pump performance.
