XTS with No Cable Technology (NCT)

Power supply and synchronous real-time data communication on XTS movers

Contactless energy and data transfer to the XTS movers

Beckhoff achieves a further quantum leap in terms of machine flexibility with a new type of technology for the XTS: No Cable Technology (NCT) enables contactless, continuous power supply and synchronous real-time data transmission to the XTS movers. The XTS modular system has been expanded to include a special motor module and electronics that can be mounted on the mover. The hardware required for NCT is fully integrated into the motor module, so that the existing functions and compact design are retained. No additional connections or supply lines are required.

With NCT, processing steps and quality control are possible for the first time directly on the mover during the running process. Sufficient power and fast communication with the TwinCAT control system make the connection of sensors and actuators easy. Data communication with each mover is real-time capable and, in conjunction with EtherCAT, synchronizes system-wide events with µs precision so that a specific event can be triggered at an exact position. Especially in the areas of product handling, processing and measuring parallel to transport as well as machine adaptations for quickly changing production batches, NCT offers users new solution possibilities.

XTS function extension with NCT enables new dimension of machine flexibility

With the No Cable Technology extension of the XTS system, production companies can tap into the advantages of highly flexible systems with minimal effort in order to meet current market trends. The increasing number of variants with shorter product life cycles and limited production space require the most versatile use of the machine possible. To meet this challenge, the XTS offers numerous possibilities to replace complex external mechanics with individual movements of the XTS movers, and thus with pure software functionality. In addition to the previous purely passive product transport, NCT enables additional process sequences directly on the mover itself – both during movement and when at a standstill.

XTS with NCT increases production output: through mobile processing stations

NCT transfers energy wirelessly to the mover. This energy is available to realize different motion sequences directly on the mover with the help of motors. The CNC-based motion sequence is synchronized with the positioning of the mover in real time. The central software approach in TwinCAT allows simple synchronization with external processing stations. In this way, the mover becomes an active part of the manufacturing process as a mobile processing station, e.g. by performing a product alignment by means of a rotary movement or by manipulating a product in order to position a carton or screw on a screw cap. The process times for feeding and removal at alternative processing stations are eliminated and the product flow no longer needs to be interrupted. Consequently, the efficiency of the machine increases and the production output increases.

Application examples:

  • alignment of products, e.g. aligning a workpiece holder to processes
  • processing of products, e.g. drilling of small holes or pinching
  • rotation of products, e.g. mixing of products, 360° product detection by a camera
  • manipulation of products, e.g. positioning a carton

XTS with NCT reduces the footprint: through highly flexible multi-robot systems

With NCT, every mover becomes a moving handling system. By means of electric motor-driven grippers, electric lifting magnets or vacuum suction units, a mover can pick up, deposit, transfer, align and stack products. Individual pick-up from an unsorted and irregular product flow as well as subsequent sorting, e.g. into good and bad parts or orderly product placement in the final packaging, is also possible. XTS achieves a particularly high sorting performance through a circulating travel movement, i.e. without movement against the product flow, as is necessary with robot arms.

The throughput is increased without further space requirement by a large number of movers with integrated product pick-up. Each mover can perform multi-axis movements and thus allows product alignment in the X, Y and Z directions, whereby one axis is already taken over by the travel movement of the movers. Additional degrees of freedom can be achieved by rotary movements. TwinCAT controls the interaction of the axes via CNC functions. This integration turns XTS into a flexible multi-robot system that increases sorting performance while reducing the required installation space to a minimum.

Application examples:

  • divide and reunite product flows, e.g. by mechatronic transfers between two movers
  • sorting out products, e.g. by means of an integrated pusher on the mover
  • product alignment in X, Y and Z direction, e.g. for synchronization with external process steps
  • electrically operated tool changer e.g. by mechanical coupling
  • adaptation of the mover attachment, e.g. to different product sizes
  • picking up and depositing of products, e.g. for product sorting by means of vacuum suction units

XTS with NCT increases quality: through on-the-fly measurement technology

The supply voltage on the mover enables the temperature control of the product during transport. In addition to the generation of physical quantities, measurement tasks can be carried out not only inline during the ongoing production process, but also in process and in parallel to the processing station or during the transport movement. For this purpose, the mover is equipped with sensors for recording measured variables. For measurements at standstill, the mover can be fixed via a holding brake. The measured values can be directly and easily linked to the product, which supports its complete traceability from the order through the production process to delivery.

A fully monitored and controlled dosing process can be carried out, for example, with a load cell for recording the product weight, since a comparison of the target and actual fill quantity is carried out in real time on the basis of the transmitted process data. This 100 percent monitoring enables the early detection of abnormalities and thus the direct initiation of appropriate countermeasures. A filling station with a suddenly reduced flow rate can be recognized immediately by its filling curve, which is too flat; however, complete filling is still possible. It remains locked to the production process until the next maintenance to ensure product quality and production performance throughout the process. This "on the fly" quality assurance eliminates additional process steps and the product can remain on the mover throughout the entire production process. Overall, this significantly increases machine efficiency.

Application examples:

  • determining the weight of products, e.g. for controlling filling processes
  • measurement of products, e.g. mover as moving measuring unit
  • presence check of products, e.g. material loading of the mover
  • condition monitoring of products and mover attachments
  • display of product states on the mover, e.g. to differentiate between OK and NOK
  • fixing of movers by means of a holding brake, e.g. to prevent damage in the event of an unexpected power failure
  • functional testing of products, e.g. testing of electronic components
  • temperature control of products, e.g. heating liquids

XTS with NCT enables a wide variety of process solutions: through open interfaces

NCT offers the user integrated data communication and thus access to the electronics of the mover. Production data or system configurations can be stored directly in a memory, thus ensuring unambiguous mover, tool and product identification. The mover also offers condition monitoring of the tools on it.

The data communication of the mover also provides an open interface with direct linking to the TwinCAT control system. This enables the connection of standardized devices on the moving mover. One example is the cyclic reading of an ultrasonic sensor via an RS485 communication interface, which can be used for distance control. All in all, a broad product portfolio – sensors and actuators – can be integrated on the movers.

Application examples:

  • unambiguous identification of movers and products, e.g. for product tracking
  • control of a print head mounted on the mover, e.g. for digital printing
  • storing and reading out information on the product, e.g. electronic storage of configuration settings or production information
