Automation adapts to manufacturing needs
Autonomous machine technology in the future will enable the adaptive machine to achieve mass customization cost-effectively
It seems inevitable that the amount of innovative technology in machine and factory automation will continue to escalate out of necessity. “We are going to need more automation as our planet’s demographics give us more people to take care of and fewer people to do the work," says John Kowal, director, business development at B&R Industrial Automation.The automation will move from the low-hanging-fruit types of applications to those more difficult to automate. And it sounds like that will change the face of automation. "We will need to be more efficient and automate tasks that aren’t cost-effective to automate today," says Kowal. "Therefore, the automation tools are going to have to become more sophisticated, so that they can be…

Safety relay or safety-rated PLC?
Safety Applications Become More Complex When More Than Three Inputs Must Be Monitored and Controlled
Machine and robot builders often need safety-rated monitoring and control, which can be accomplished with safety-rated relays or PLCs. "Many applications could use either a safety relay or PLC, but the choice depends on four main considerations: complexity, flexibility, availability and footprint," says George Schuster, senior industry specialist for the automotive team at Rockwell Automation.

Safety applications become complex when more than about three inputs must be monitored and controlled, or when communication over a digital network is required. "Safety relays are hardwired to perform simple diagnostics and logic, and work well when the amount of safety points in the application…

Are servo and stepper functionalities merging?
How many differences still remain between these motors?
With the advancement of motor control and construction, the operational difference between servo motors and stepper motors has become minimal. Theoretically, a servo motor can move to an infinitely small fraction of a rotational degree, whereas a stepper motor is limited by the number of individual stator windings that create each step. Practically, these limitations do not exist.In general, a servo motor is just a part of a servo system. The system consists of a motor, a drive and a feedback device.The drive, or amplifier, takes the incoming ac power and rectifies it to supply a dc voltage to the drive circuitry. The drive can be a simple rectifier with power relays controlled by external control circuitry. This type of drive relies on…

Once clean, dry air at the proper pressure is connected and safe, get control of the pneumatic cylinders, actuators and motors with proper valve selection and flow control.
Supplying clean, dry air is an important starting point to long and reliable valve operation in industrial machines and equipment. However, switching the air through the proper type of valve to control the cylinder, actuator or air motor is where is where fluid power is controlled.
Pneumatics are a great choice for many machine linear and rotary applications. Unless the machine requires accurate, programmable motion-positioning electric motors or the high-force capabilities of hydraulics, a pneumatic solution is often the best and most popular choice. Instead of electricity, design in some pneumatic air preparation hardware, tubing, valves, solenoids and flow controls, connect to the pneumatic cylinders, actuators and motors and get the…

3D machine vision systems give robots the ability to act without the need for CAD data
Remember the gold or blue dress debate? The human eye is undoubtedly impressive, but it has some limitations. Luckily, machine vision is rapidly taking responsibility for inspection, validation and motion control processes.Robots bring the most value to dull, repetitive and mundane tasks. Pick-and-place applications, for example, require little skill. However, these tasks do put repetitive strain on the employee. That said, the dexterity and accuracy needed to pick an item out of a bin and place it onto a conveyor cannot be taken for granted—not just any old robot can do this job.Automating this process becomes challenging when you consider the random assortment of parts in a bin, a common challenge for food-and-beverage manufacturing.

The challenge in any design is to incorporate all the features that your customer desires without making a whole new design each time. Previously, I’ve discussed ways we can modularize our designs to leverage the experience we gained in previous projects. While this approach is good, sometimes it can lead to designs that don’t take advantage of the technical advances the hardware itself can provide. A good design is a healthy mix of tried and true with new and innovative.As a contract packager, we come upon challenges on a daily basis. Some can be solved by reusing solutions from similar opportunities, while others need a new approach. One such application is a means by which to sense product dropping from a quad cup filler. A cup…

Another challenge is how to convey the myriad facets of compliance comprehensibly to end customers and integrators for issues such as knowing when a robot system is really compliant or what the requirements to which the robot and robot system have to comply are.
The first thing, which has to be clarified for the topic of compliance, is always in what industry and for which purpose the robot system will be used. Compliance requirements differ from…
