Electronic position indicators with radio data transmission

EN  9153 digital position indicators with data transmission via radio frequency are particularly suited for frequent format adjustments and can be mounted quickly and easily. They are connected to the EN  9150 control unit by radio frequency as a wireless system for quick positioning.

EN 9150 control units are required for the system to function. They form the interface between the position indicator and the machine control. A target position value is sent by the machine control to the control unit, which transmits this via radio frequency to the position indicator. The position indicator signals its current position value back to the control unit.

In combination with the machine control, this makes it possible to ensure that the production cycle does not start when the position set on the position indicator is incorrect, which can prevent errors in the production process.

Increased efficiency in warehouse automation

Published

on

E-commerce is booming and with it warehouse automation. Flexible storage systems are also in demand in warehouses of large food chains, which require environmentally friendly, sustainable and intelligent drive concepts. The drive specialist NORD DRIVESYSTEMS knows exactly the needs of the industry and offers a variety of dynamic drive solutions that meet different applications and requirements in warehouse logistics.

The company offers customized drive solutions for warehouse logistics for an optimal compromise between investment, operating and maintenance costs. The drive units with motor efficiency class IE4 and system efficiency class IES2 achieve excellent efficiencies especially in the partial load and partial speed range. With the latest generation IE5+ permanent magnet synchronous motor, even higher energy efficiency can be achieved and energy consumption significantly reduced. The constant torque over a wide speed range also enables targeted variant reduction. In this way, administrative expenses can be minimized and manufacturing, logistics, storage and service processes can be streamlined.

The decentralized frequency inverter 

The NORDAC ON decentralized frequency inverter was developed specifically for the requirements of horizontal conveyor technology in the warehouse area and the NORDAC ON+ variant for interaction with the new IE5+ synchronous motor. It is characterized by an integrated Ethernet interface, its ease of maintenance due to complete pluggability, and extremely compact design, and offers an economical as well as intelligent plug-and-play solution for IIoT environments. The compact, smart frequency inverter for decentralized use can be mounted directly on the gearmotor. It covers smaller power ranges up to 2.2 kW and offers an energy-saving function in the partial load range. The integrated Ethernet interface reduces the effort required for integration into modern automation systems: Whether ProfiNET, EtherNET IP or EtherCAT, the desired protocol can be easily set via parameters.

More efficiency in conveyor technology

The NORDAC FLEX SK 205E series is also ideal for applications in warehouse logistics. The compact, decentralized, and energy-efficient frequency inverter offers a wide power range up to 22 kW and enables energy savings across the entire load range. The inverter can be used to control standard asynchronous motors, high-efficiency synchronous motors and brake motors. It can be installed close to the drive in the field or mounted on the motor.

Power and data cables can be connected in a plug-in manner. The decentralized system allows short motor and encoder cables as well as short supply cables to sensors. Encoder feedbacks can be implemented, for example, for position-controlled transport systems. Since the NORDAC FLEX SK 205E offers a high overload capacity, dynamic movements with short start and stop times or cycle operation are also possible. The integrated control enables high accuracy in synchronous and positioning applications.

Modular system for optimum drive solutions

Overall, the company impresses with a wide range of products for the warehouse sector, including both established basic and high-efficiency products. The user benefits from customized and reliable drive solutions that ensure optimum system availability. The modular drive system thus enables an optimum compromise between investment, operating and maintenance costs.

Collaboration to develop innovative 3D printing technology

Published

on

3D printing solutions manufacturer BCN3D Technologies and global leader in adhesives, sealants and functional coatings Henkel Adhesive Technologies today announced a collaboration to develop formulations for the recently introduced Viscous Lithography Manufacturing (VLM)™ 3D printing technology. This official announcement is the latest step in an alliance between the two teams that has been in place since 2020.

With more than 100 years of experience in cross-industry applications, Henkel is more than qualified to provide end-to-end engineering solutions for additive manufacturing (AM), largely through its well-known Loctite brand. Accordingly, the company will use the collaboration to develop new materials for printing technology, advancing its vision of manufacturing autonomy to give manufacturers full control over every stage of the production process with AM.

The joint work is expected to leverage the properties to develop new solutions for high-performance resins. The technology is a patented lithography-based 3D printing process that laminates thin layers of high-viscosity resins onto a transparent transfer film to quickly and cost-effectively produce high-performance components. What sets the printing technology apart from other resin technologies on the market is its ability to process resins that are 50 times more viscous than the industry standard. By eliminating the strict restriction of low viscosity, a whole new range of ingredients and modifiers can be added to the resin to achieve the desired effect on thermal and mechanical properties.

The materials currently being developed by the two companies cannot yet be fully disclosed; however, one of the main areas of research is elastomeric applications – an area that will undoubtedly benefit from high-viscosity resins. These materials can contain a high proportion of oligomers to provide a loosely cross-linked polymer network: a structure that can flexibly withstand mechanical loads, behave like an industrially molded elastomer, and exhibit improved mechanical properties.

“BCN3D has introduced a breakthrough technology that enables printing of highly viscous resins. Thermal and mechanical properties are improved by additives that normally increase the viscosity of resins, which in other cases makes them difficult to print. The team has developed a novel technology that removes viscosity limitations and enables printing of a wide range of new materials, which we have seen firsthand over the past few years of collaboration. We look forward to seeing the tremendous impact this technology, along with Henkel Industrial’s new resins, will have on the additive market.”

– Sam Bail, Director of 3D Printing & Partnerships

Henkel’s 3D printing resins will be used in the new application center where the program will take place. Participants, along with renowned companies Saint Gobain and Prodrive, will be the first to discover the VLM and experience its full potential for themselves with real 3D-printed parts, accompanied by personalized support to meet their exact printing needs.

The first official highlight of this joint venture will take place at Rapid, May 17-19, 2022, at booth 1535, Huntington Place, Detroit, Michigan, where both companies will explain and illustrate the benefits of such collaboration while demonstrating 3D-printed parts produced with VLM.
