Drive and automation specialist Baumüller has extended its new SAF 002/003 safety modules of the b Maxx 5000 converter series with a freely parameterizable delay time. The delay time is switched between a safety function and the associated error reaction Safe Torque Off (STO). This provides optimum protection for the machine mechanics against damage in the event of a fault and minimizes downtimes.

Typically, the safety modules are equipped with various safety functions that can be used for safe monitoring when required. For example, if a limit value violation is detected during the safe monitoring of a speed, the system reacts by triggering the STO function, which switches the drive torque-free. However, in this case the motor may not come to a controlled standstill, which means it may coast down.

The benefits: risk prevention and increased productivity

Baumüller has now developed an innovation for the SAF 002/003 safety modules: The parameterizable delay time is a time window, individually user-programmable depending on the safety function, which is switched between the safety functions and the STO function.

For example, if during active Safe Limited Speed (SLS) speed monitoring the previously parameterized speed is exceeded, the delay time is started. The safety module simultaneously sends a signal to the converter to perform a specific action. This action can be parameterized in advance; for example, the converter decelerates the drive in a controlled manner within the set time. Only when the machine has come to a standstill is the drive safely switched torque-free.

Application: embroidery machine

One typical area of application for this function is in the textile industry. If a machine operator moves within the danger zone of a machine, it can automatically start safe monitoring and reduce the speed (SLS).

If the active speed monitoring SLS detects that the set speed limit has been exceeded, the safety module automatically switches on the previously parameterized delay time before triggering the STO function.

The controller receives the signal to remove the needle from the fabric within this time before STO is executed and the drive is switched torque-free. This functionality can, for example, prevent needle breakage or an error in the embroidery pattern and allow production to resume swiftly.

With its campus networks, Deutsche Telekom offers an infrastructure for the smart factory of tomorrow. Together with partners from industry, Europe’s largest telecommunications company wants to further expand its 5G ecosystem for industry. In process automation, Deutsche Telekom is now cooperating with Endress + Hauser.

The aim of the cooperation is to develop joint offers in the field of measurement and automation technology for the process industry. This involves the integration of measuring instruments and accessories into the next generation of mobile communication networks as well as digital services based on them. Both companies have signed a corresponding memorandum of understanding and are now working on a coordinated timetable.

Measuring instruments with mobile communication module

Endress + Hauser is one of the first manufacturers to equip its field devices with mobile communication modules and to connect existing installations to 5G networks via newly developed Hart gateways. This enables a large number of instruments to transmit a wealth of process and device data in parallel and in real time. These can, for example, be used in cloud applications for predictive maintenance of process plants.

Campus networks open second signal path

“In addition to the actual measured values, our instruments record a wealth of information from the process and about the sensor. 5G campus networks open up a second signal path that is independent of the plant’s control system and thus make it possible to tap this potential. This will enable us to link value chains more closely across company boundaries and make industrial processes more efficient.”

Matthias Altendorf, CEO of Endress + Hauser

Strong partners for smart production

“Building a complete 5G ecosystem for industry will accelerate the pace of digitalization in industry,” explains Claudia Nemat, member of the Deutsche Telekom Board of Management, Technology and Innovation. “We look forward to working with renowned and experienced partners.” In addition to the partnership with network supplier Ericsson, the telecommunications company now also cooperates with E&K Automation, a manufacturer of driverless transport systems, and Konica Minolta, which offers augmented reality glasses, among other products.

Coperion K-Tron is proud to announce a completely new K3 line of vibratory feeders for dry bulk solids.  The innovative new feeder design features a unique, patent-pending drive system combined with an advanced control package.  The new K3 vibratory feeder is able to achieve accuracies averaging 35% better over traditional vibratory technologies. This revolutionary new generation of Coperion K-Tron loss-in-weight vibratory feeders offers gentle handling of the bulk material, higher accuracy and faster product changeover, resulting in less product waste, less downtime and better end product quality as well as improved sustainability.

New technology brings significant advantages

These advantages are possible thanks to groundbreaking new technology. The key to achieving high accuracy is the ability to deliver a continuous, even product discharge with minimal pulsations. The new K3 vibratory drive is able to do this thanks to a completely new shock absorber design. Conventional vibratory feeders use rubber or spring shock absorbers, which allow movement of the drive in all directions, resulting in rotational motion. In contrast to these conventional shock absorbers, the new K3 line uses a unique flexible pendulum technology which provides shock absorption only parallel to the desired direction of motion, eliminating rotational movement. This parallel motion ensures an even material flow of the product along the entire length of the tray.

The advanced control system and feeder electronics include internal sensors which measure acceleration, displacement, load, current and temperature at rates of up to 25,000 times per second. The fast-acting controller then adjusts the vibratory drive signal to maintain clean sinusoidal displacement for optimal mass flow. The combination of this unique drive with the Coperion K-Tron SmartConnex control system also results in extremely low energy consumption as compared to other feeding technologies. Power consumption can be as low as 20 Watts for feed rates as high as 6,000 kg/h, thus making it ideal for improved production sustainability and minimal heat dissipation.

The typical feeder package consists of a feed hopper, vibratory tray and vibratory drive mounted on a weighing system featuring patented, high accuracy Smart Force Transducer weighing technology and combined with SmartConnex controls. The mechanical package is modular in design, and versatile in that it can accommodate custom tray configurations and lengths, offering the user more flexibility.  A special quick-release clamp mechanism on the feeder tray allows for quick product changeover. The absence of mechanical wear parts results in lower maintenance requirements and ensures gentle handling of the bulk material. In addition to the standard design, a line of hygienic, easy-clean configurations is also available. These include a hygienic silicone cover to enclose the complete drive assembly, making it also suitable for food and pharmaceutical applications.

Ideal for gentle handling of difficult bulk materials

Vibratory feeders are ideal for the gentle handling of a wide variety of materials, including friable products, abrasive products, products with non-uniform shapes, and glass fibers. They are ideally suited to applications such as the high accuracy feeding of finished food products to packaging lines, uncoated tablets to coating lines, as well as difficult feeding of pellets or regrind to plastic extrusion lines, for example in plastic recycling applications.. Vibratory feeders can often be a viable alternative to screw feeders for difficult materials, where gentle vibratory feeding may allow feeding without build-up which can occur on screws and screw tubes.
